Selected Historical Consolidated Financial Data for ICON plc

The following selected financial data set forth below are derived from the Company’s consolidated financial statements and should 
be read in conjunction with, and are qualified by reference to, Item 5 “Operating and Financial Review and Prospects” and the 
Company’s consolidated financial statements and related notes thereto included elsewhere in this Form 20-F.

The Company adopted ASC 606 'Revenue from Contracts with Customers' ("ASC 606") with a date of initial application of January 
1, 2018.  The new revenue recognition policies were applied in the preparation and presentation of the results for the twelve months 
ended December 31, 2018. As ICON adopted the standard using the cumulative effect transition method, there is no restatement 
of comparative amounts. The results for the year ended December 31, 2017 and previously therefore reflect the provisions of ASC 
605 'Revenue Recognition'.  The most significant impact of application of the new standard reflects the measurement of a clinical 
trial service as a single performance obligation recognized over time.  We concluded that ICON is the contract principal in respect 
of both direct services and in the use of third parties (principally investigator services) that support the clinical trial.  The progress 
towards completion for clinical service contracts is measured based on total project costs (direct fees are therefore inclusive of 
third party costs). Revenue is our primary measure of performance on adoption of ASC 606.  In common with others in the sector, 
our results previously separately identified that revenue stream which related to services provided by third parties.  Those services 
were  previously  separately  identified  as  reimbursable  expenses  and  presented  separately  in  our  Statement  of  Operations.  
Reimbursable expenses are included within direct costs on adoption of ASC 606. Throughout the document revenue as reported 
on adoption of ASC 606 is referred to as revenue. Revenue as reported for the years ended December 31, 2017 and previously are 
gross revenues (inclusive of revenue from reimbursable expenses) or net revenues (excluding revenue from reimbursable expenses).  
This treatment is consistent with the adoption of ASC 606 from January 1, 2018 without restatement of comparatives. See note 
26 for impact of new accounting policy.

(2)  A restructuring charge of $12.5 million was recognized during the year ended December 31, 2018, under a restructuring 
plan adopted following a review of operations.  The restructuring plan reflected resource rationalization across the business 
to improve resource utilization. See Note 14 to the Audited Consolidated Financial Statements.

(3)  A restructuring charge of $7.8 million was recognized during the year ended December 31, 2017, under a restructuring 
plan adopted following a review of operations.  The restructuring plan reflected resource rationalization across the business 
to improve resource utilization. See Note 14 to the Audited Consolidated Financial Statements.

(4)  A restructuring charge of $8.2 million was recognized during the year ended December 31, 2016 under a restructuring 
plan  adopted  following  a  review  by  the  Company  of  its  operations. The  restructuring  plan  includes  resource 
rationalizations in certain areas of the business to improve resource utilization and improve operational effectiveness, 
resulting in a charge of $6.2 million, and office consolidation which resulted in the recognition of an onerous lease 
obligation of $2.0 million. See Note 14 to the Audited Consolidated Financial Statements.

income per share includes potential ordinary shares from the exercise of options.

Risk Factors

Various risk factors that are relevant to our business and the services we provide are outlined below. If any of these events were 
to occur, our business operations and financial results could be materially adversely affected.

Risk Related to Our Business and Operations

We depend on a limited number of customers and a loss of, or significant decrease in business from one or more of them could 
affect our business.

During the year ended December 31, 2018 39.5% of our revenues were derived from our top five customers, with one customer 
contributing more than 10% of our revenues during the period (13.6%). During the year ended December 31, 2017 42% of our  
revenues (including revenue from reimbursable expenses)  were derived from our top five customers, with one customer contributing 
more than 10% of our revenues (including revenue from reimbursable expenses) during the period (21.0%).  No other customer 
contributed more than 10% of our net revenues during this period. See note 16 Disaggregation of revenue.  

During the year ended December 31, 2016 45% of our net revenues (excluding revenue from reimbursable expenses) were derived 
from  our  top  five  customers,  with  one  customer  contributing  more  than  10%  of  our  net  revenues  (excluding  revenue  from 
reimbursable expenses) during the period (26%). No other customer contributed more than 10% of our net revenues during this 
period. The loss of, or a significant decrease in business from one or more of these key customers could have a material adverse 
impact on our results of operations and financial results.

Many of our contracts are long-term fixed-fee contracts. We would lose money in performing these contracts if the costs of 
performance exceed the fixed fees for these projects and we are unable to negotiate a change order for the value of work 
performed.

Many of our contracts are long-term fixed fee contracts. Revenues on these contracts are agreed in the contract between the 
Company  and  the  customer  and  are  based  on  an  assessment  of  progress  towards  completion  based  on  the  cost  of  time  and 
reimbursable  costs.  Factors  considered  in  estimating  time  requirements  include  the  complexity  of  the  study,  the  number  of 
geographical sites where trials are to be conducted and the number of patients to be recruited at each site. The Company regularly 
reviews the estimated hours on each contract to determine if the budget accurately reflects the agreed tasks to be performed taking 
into account the state of progress at the time of review. The Company also endeavors to ensure that changes in scope are appropriately 
monitored and change orders for additional revenue are promptly negotiated for additional work as necessary.  If we were to fail 
to successfully negotiate change orders for changes in the resources required or the scope of the work to be performed and the 
costs of performance of these contracts exceeded their fixed fees, it could materially adversely affect our operations and financial 
results.

If our customers discontinue using our services, or cancel or discontinue projects, our revenue will be adversely affected and/
or we may not receive their business in the future or may not be able to attract new clients.

Our clients may discontinue using our services completely or cancel some projects either without notice or upon short notice. The 
termination or delay of a large contract or of multiple contracts could have a material adverse effect on our revenue and profitability. 
Historically,  clients  have  cancelled  or  discontinued  projects  and  may  in  the  future  cancel  their  contracts  with  us  for  reasons 
including, amongst others:

• 

• 

• 

• 

• 

the failure of products being tested to satisfy safety or efficacy requirements;

unexpected or undesired clinical results of the product;

a decision that a particular study is no longer necessary or viable;

poor project performance, quality concerns, insufficient patient enrollment or investigator recruitment; and

production problems resulting in shortages of the drug.

If we lose clients, we may not be able to attract new ones and if we lose individual projects, we may not be able to replace them.

If we fail to attract or retain qualified staff, our performance may suffer.

Our business, future success and ability to continue to expand operations depends upon our ability to attract, hire, train and retain 
qualified professional, scientific and technical operating staff. We compete for qualified professionals with other Clinical Research 
Organizations “CROs”, temporary staffing agencies and the in-house departments of pharmaceutical, biotechnology and medical 
device companies. An inability to attract and retain a sufficient number of high caliber clinical research professionals (in particular, 
key personnel and executives) at an acceptable cost would impact our ability to provide our services, our future performance and 
results of operations.

Our ability to perform clinical trials is dependent upon the ability to recruit suitable willing patients.

The successful completion of clinical trials is dependent upon the ability to recruit suitable and willing patients on which to test 
the drug under study. The availability of suitable patients for enrollment on studies is dependent upon many factors including, 
amongst others, the size of the patient population, the design of the study protocol, eligibility criteria, the referral practices of 
physicians,  the  perceived  risks  and  benefits  of  the  drug  under  study  and  the  availability  of  alternative  medication,  including 
medication undergoing separate clinical trials. Insufficient or inappropriate patient enrollment may result in the termination or 
delay of a study which could have a material adverse impact on our results of operations. 

The Company is focused on continuing to develop its expertise in patient recruitment. The focus is on making it easier for the site 
and the patient to actively participate in a trial to ensure increased predictability, enrolment and retention. Our site and patient 
solutions group includes upfront planning of site and patient management including identification, enrolment and engagement.  

Improved site selection is achieved through:

• 

• 

• 

leading technology to identify where the patients are that match the protocol;

assessment of the qualification of sites based on real data;

partnerships with leading technology vendors such as Intel, EHR4CR and TriNeTX and developing the capability to 
enable EMR interrogation into clinical insights such as sub-populations and larger pre-screened pool where the technology 
and regulations are enabled.  

The burden on the site in ensuring patient enrolment and engagement is achieved through integrated site networks. ICON have a 
number of site alliance partners. During 2018, we enhanced our site and patient recruitment capabilities with an expansion of the 
PMG  Research  network  through  a  partnership  with  the  Du  Page  Medical  Group.  We  also  use  digital  solutions  to  drive  site 
performance, including pre-screening, eConsent, learning management, document tracking and management with key applications.  

5

 
 
 
 
 
 
 
Our ability to perform clinical trials is dependent upon our ability to recruit suitable willing investigators.

We contract with physicians located in hospitals, clinics or other similar sites, who serve as investigators in conducting clinical 
trials to test new drugs on their patients. Investigators supervise administration of the study drug to patients during the course of 
the clinical trial. The successful conduct of a clinical trial is dependent upon the integrity, experience and capabilities of the 
investigators conducting the trial. Insufficient investigator recruitment, which in turn may lead to insufficient or inappropriate 
patient enrollment, may result in the termination or delay of a study which could have a material adverse impact on our results of 
operations.

We rely on third parties for important products and services.

We depend on certain third parties to provide us with products and services critical to our business.  Such services include, amongst 
others, suppliers of drugs for patients participating in trials, suppliers of kits for use in our central laboratory business, suppliers 
of reagents for use in our testing equipment and providers of maintenance services for our equipment. The failure of any of these 
third parties to adequately provide the required products or services or the significant increase in the costs of such products and 
services could have a material adverse effect on our business.

Our business depends on the continued effectiveness and availability of our information systems, including the information 
systems we use to provide our services to our clients, and any system failures of, security breaches of or cyber-attacks to these 
systems may materially limit our operations or have a material adverse effect on our results of operations. 

Due to the global nature of our business and our reliance on information systems to provide our services, we use web-enabled and 
other integrated information systems in delivering our services. We will to continue to increase the use of these systems and such 
systems  will  either  be  developed  internally  or  provided  in  conjunction  with  third  parties. We  also  provide  access  to  similar 
information systems to certain clients in connection with the services we provide them. As the use, scope and complexity of our 
information systems continue to grow, we are exposed to and will increasingly be exposed to the risks inherent in the development, 
integration and ongoing operation of evolving information systems, including:

• 

• 

disruption or failure of data centers, telecommunications facilities or other key infrastructure platforms;

security  breaches,  cyber-attacks  or  other  failures  or  malfunctions  in  our  application  or  information  systems  or  their 
associated hardware or other systems that we have access to or that we rely upon or that have access to our systems; and

• 

excessive costs, excessive delays or other deficiencies in or problems with systems development and deployment.

The materialization of any of these risks may impede our ability to provide services, the processing of data, the delivery of databases 
and services and the day-to-day management of our business and could result in the corruption, loss or unauthorized disclosure 
of proprietary, confidential or other data, as well as reputational harm. While we have cybersecurity controls and disaster recovery 
plans in place, they might not adequately protect us in the event of a system failure, security breach or cyber-attack. Despite any 
precautions we take, damage from fire, floods, hurricanes, power loss, telecommunications failures, computer viruses, information 
system security breaches, cyber-attacks and similar events that impact on our various computer facilities could result in interruptions 
in the flow of data to our servers and from our servers to our clients. Corruption or loss of data may result in the need to repeat a 
trial at no cost to the client, but at significant cost to us, or result in one or more of the termination of a contract, legal proceedings 
or claims against us or damage to our reputation. Additionally, significant delays in system enhancements or inadequate performance 
of new or upgraded systems once completed could damage our reputation and harm our business. Long-term disruptions in the 
infrastructure caused by events such as security breaches, cyber-attacks, natural disasters, the outbreak of war, the escalation of 
hostilities and acts of terrorism, particularly involving cities in which we have offices, could adversely affect our business.

Unauthorized  disclosure  of  sensitive  or  confidential  data,  whether  through  system  failure  or  employee  negligence,  fraud  or 
misappropriation, could damage our reputation and cause us to lose clients. Similarly, despite investing in information and cyber-
security controls there is a risk that unauthorized access to or through our information systems or those we develop for our clients, 
whether by our employees or third parties, including a cyber-attack by computer programmers and hackers who may attack ICON 
systems, develop and deploy viruses, worms, ransomware or other malicious software programs could result in negative publicity, 
significant remediation costs, legal liability, loss of customers and damage to our reputation and could have a material adverse 
effect on our results of operations and financial results. In addition, our liability insurance might not be sufficient in type, the cover 
provided or amount to adequately cover us against claims related to security breaches, cyber-attacks and other related breaches.

Upgrading the information systems that support our operating processes and evolving the technology platform for our services 
pose risks to our business. 

Continued efficient operation of our business requires that we implement standardized global business processes and evolve our 
information systems to enable this implementation. We have continued to undertake significant programs to optimize business 
processes with respect to our services. A failure to effectively manage the implementation and adapt to new processes designed 
into these new or upgraded systems in a timely and cost-effective manner may result in disruption to our business and negatively 
affect our operations.

We have entered into agreements with certain vendors to provide systems development and integration services that develop or 
license to us the IT platform for programs to optimize our business processes. If such vendors fail to perform as required or if 
there are substantial delays in developing, implementing and updating the IT platform, our customer delivery may be impaired 
and we may have to make substantial further investments, internally or with third parties, to achieve our objectives. Additionally, 
our progress may be limited by parties with existing or claimed patents who seek to prevent us from using preferred technology 
or seek license payments from us.

Meeting our objectives is dependent on a number of factors which may not take place as we anticipate, including obtaining adequate 
technology-enabled services, creating IT-enabled services that our customers will find desirable and implementing our business 
model with respect to these services. If we do not keep pace with rapid technological changes in the CRO industry, our products 
and services may become less competitive or even obsolete. This applies in particular to our ICONIK, Firecrest and ADDPLAN 
and  One  Search  services. Also,  increased  requirements  for  investment  in  information  technology  may  negatively  impact  our 
financial condition, including profitability. 

We rely on our interactive response technologies to provide accurate information regarding the randomization of patients and 
the dosage required for patients enrolled in the trials. 

We develop and maintain computer run and web based interactive response technologies to automatically manage the randomization 
of patients in trials, assign the study drug and adjust the dosage when required for patients enrolled in trials we support. An error 
in the design, programming or validation of these systems could lead to inappropriate assignment or dosing of patients, which 
could give rise to patient safety issues, incorrect dosing of patients, invalidation of the trial and/or liability claims against the 
Company, amongst other things, any of which could have a material effect on our financial condition and operations.

Our operations might be impacted by a disruption to travel systems.

Many of our operations rely on the availability of air or other transportation for the distribution of clinical trial materials, study 
samples and personnel. While we have developed contingency plans to minimize the impact of such events, a disruption to the 
availability of air transportation or other travel systems could have a material adverse impact on our ability to provide services 
and results of operations.

We may make, or be unable to make, acquisitions in the future, which may lead to disruptions to our ongoing business.

We have made a number of acquisitions and will continue to review new acquisition opportunities. If we are unable to identify 
suitable acquisition targets, complete an acquisition or successfully integrate an acquired company or business, our business may 
be disrupted. The success of an acquisition will depend upon, among other things, our ability to:

• 

• 

• 

• 

effectively and quickly assimilate the operations and services or products of the acquired company or business; 

integrate acquired personnel; 

retain and motivate key employees; 

retain customers; and 

•  minimize the diversion of management's attention from other business concerns.

In the event that the operations of an acquired company or business do not meet our performance expectations, we may have to 
restructure the acquired company or business or write-off the value of some or all of the assets of the acquired company or business.
7

 
Improper performance of our services

The performance of clinical development services is complex and time-consuming. We may make mistakes in conducting a clinical 
trial that could negatively impact or damage the usefulness of the clinical trial or cause the results to be reported improperly.  If 
the clinical trial results are compromised, we could be subject to significant costs or liability, which could have an adverse impact 
on our ability to perform our services. Large clinical trials are costly, and while we endeavor to contractually limit our exposure 
to such risks, improper performance of our services could have an adverse effect on our financial condition, damage our reputation 
and result in the cancellation of current contracts or failure to obtain new contracts from affected or other clients. 

Our relationships with existing or potential customers who are in competition with each other may adversely impact the degree 
to which other customers or potential customers use our services, which may adversely affect our results of operations.

The  biopharmaceutical  industry  is  highly  competitive,  with  biopharmaceutical  companies  each  seeking  to  persuade  payers, 
providers and patients that their drug therapies are better and more cost-effective than competing therapies marketed or being 
developed by competing companies. In addition to the adverse competitive interests that biopharmaceutical companies have with 
each other, biopharmaceutical companies also have adverse interests with respect to drug selection and reimbursement with other 
participants in the health care industry, including payers and providers. Biopharmaceutical companies also compete to be first to 
market with new drug therapies. We regularly provide services to biopharmaceutical companies who compete with each other and 
we sometimes provide services to such customers regarding competing drugs in development. Our existing or future relationships 
with our biopharmaceutical customers may therefore deter other biopharmaceutical customers from using our services or may 
result in our customers seeking to place limits on our ability to serve other biopharmaceutical industry participants. In addition, 
our further expansion into the broader health care market may adversely impact our relationships with biopharmaceutical customers 
and such customers may elect not to use our services, reduce the scope of services that we provide to them or seek to place 
restrictions on our ability to serve customers in the broader health care market with interests that are adverse to theirs. Any loss 
of customers or reductions in the level of revenues from a customer could have a material adverse effect on our results of operations, 
business and prospects.

We have only a limited ability to protect our intellectual property rights and these rights are important to our success.

Our success depends, in part, upon our ability to develop, use and protect our proprietary methodologies, analytics, systems, 
technologies and other intellectual property. Existing laws of the various countries in which we provide services or solutions offer 
only limited protection of our intellectual property rights, and the protection in some countries may be very limited. We rely upon 
a combination of trade secrets, confidentiality policies, non-disclosure, invention assignment and other contractual arrangements 
and patent, copyright and trademark laws, to protect our intellectual property rights. These laws are subject to change at any time 
and  certain  agreements  may  not  be  fully  enforceable,  which  could  further  restrict  our  ability  to  protect  our  innovations.  Our 
intellectual property rights may not prevent competitors from independently developing services similar to or duplicative of ours. 
Further, the steps we take in this regard might not be adequate to prevent or deter infringement or other misappropriation of our 
intellectual property by competitors, former employees or other third parties and we might not be able to detect unauthorized use 
of,  or  take  appropriate  and  timely  steps  to  enforce  our  intellectual  property  rights.  Enforcing  our  rights  might  also  require 
considerable time, money and oversight and we may not be successful in enforcing our rights.

We may, in certain circumstances, grant a customer more expansive rights in intellectual property developed in connection with 
a contract than we would normally grant. In such situations, we may forego the use of all intellectual property rights we create or 
develop, which would limit our ability to reuse or deploy that intellectual property for other customers. Any limitation on our 
ability to provide a service or solution may result in us losing revenue-generating opportunities and may also result in us incurring 
additional expenses to develop or license new or modified solutions for other projects or customers.

The biopharmaceutical industry has a history of patent and other intellectual property litigation and we might be involved in 
costly intellectual property lawsuits.

The biopharmaceutical industry has a history of intellectual property litigation, and these lawsuits will likely continue in the future. 
Accordingly, we may face patent infringement legal proceedings by companies that have patents for similar business processes 
or other legal proceedings alleging infringement of their intellectual property rights. Legal proceedings relating to intellectual 
property could be expensive, take significant time and divert management’s attention from other business concerns, regardless of 
the outcome of the litigation. If we do not prevail in an infringement lawsuit brought against us, we might have to pay substantial 
damages and we could be required to stop the infringing activity or obtain a license to use technology on unfavorable terms. Any 

8

 
infringement or other legal processing related to intellectual property could have a material adverse effect on our operations and 
financial condition.

We act as legal representative for some clients.

We act as the legal representative for certain clients in certain jurisdictions. As we believe that acting as legal representative of 
clients exposes us to a higher risk of liability, this service is provided subject to our policy and requires certain preconditions to 
be met. The preconditions relate to obtaining specific insurance commitments and indemnities from the client to cover the nature 
of the exposure. However, there is no guarantee that the specific insurance will be available and provide cover or that a client will 
fulfill its obligations in relation to their indemnity.

Risk Related to Our Industry

We are dependent on the continued outsourcing of research and development by the pharmaceutical, biotechnology and medical 
device industries.

We are dependent upon the ability and willingness of the pharmaceutical, biotechnology and medical device companies to continue 
to spend on research and development and to outsource the services that we provide. We are therefore subject to risks, uncertainties 
and  trends  that  affect  companies  in  these  industries  that  we  do  not  control. We  have  benefited  to  date  from  the  tendency  of 
pharmaceutical,  biotechnology  and  medical  device  companies  to  outsource  clinical  research  projects. Any  downturn  in  these 
industries or reduction in spending or outsourcing could materially adversely affect our business. The following could each result 
in such a downturn:

• 

• 

if pharmaceutical, biotechnology or medical device companies expanded upon their in-house clinical or development 
capabilities, they would be less likely to utilize our services;

if governmental regulations were changed, it could affect the ability of our clients to operate profitably, which may lead 
to a decrease in research spending and therefore this could have a material adverse effect on our business; and

• 

if unfavorable economic conditions or disruptions in the credit and capital markets negatively impacted our clients.

Large  pharmaceutical  companies  are  increasingly  consolidating  their  vendor  base  and  entering  strategic  partnership 
arrangements with a limited number of outsource providers.

Large pharmaceutical companies are continually seeking to drive efficiencies in their development processes to both reduce costs 
associated with the development of new drug candidates and accelerate time to market. As a result, large pharmaceutical companies, 
in particular, are increasingly looking to consolidate the number of outsource providers with which they engage, with many entering 
strategic  partnership  arrangements  with  a  limited  number  of  outsource  providers. The  failure  to  enter  strategic  partnership 
arrangements with customers or the loss of existing customers as a result of them entering strategic partnership arrangements with 
our competitors could have a material adverse impact on our results of operations.

Increased collaboration amongst pharmaceutical companies in research and development activities may lead to fewer research 
opportunities.

Certain pharmaceutical companies have begun to collaborate in seeking to develop new drug candidates. Increased collaboration 
amongst  pharmaceutical  companies  may  lead  to  fewer  research  opportunities,  which  in  turn  may  lead  to  fewer  outsource 
opportunities  for  companies  within  the  CRO  industry. A  reduction  in  outsource  opportunities  as  a  result  of  this  increased 
collaboration could have a material adverse impact on our results of operations.

We operate in a highly competitive and dynamic market.

The CRO industry is highly competitive. In particular, we compete with other large global CROs for strategic relationships with 
large  pharmaceutical  companies.  If  we  are  unable  to  retain  and  renew  existing  strategic  relationships  and  win  new  strategic 
relationships, there would be a material adverse impact on our results. Similarly, we compete with other CROs for work which 
comes outside of these strategic relationships and being unable to win work outside of these strategic relationships would have a 
material adverse impact on our results.

The type and depth of services provided by CROs has changed in recent years. Failure to develop and market new services or 
expand existing service offerings could adversely affect our business and operations.

9

 
New entrants may also enter the market which would further increase competition and could adversely affect our business and 
operations.

Risk Related to Our Financial Results and Financial Position

Our quarterly results are dependent upon a number of factors and can fluctuate from quarter to quarter.

Our results of operations in any quarter can fluctuate or differ from expected or forecast results depending upon or due to, among 
other  things,  the  number  and  scope  of  ongoing  client  projects,  the  commencement,  postponement,  variation,   cancellation  or 
termination of projects in a quarter, the mix of activity, cost overruns, employee hiring and other factors. Our revenue in any period 
is directly related to the number of employees who were working on billable projects together with investigator activity during 
that period. We may be unable to compensate for periods of under-utilization during one part of a fiscal period by earning revenue 
during another part of that period. We believe that operating results for any particular quarter are not necessarily a meaningful 
indicator of future results.

Also, if in future quarters, we are unable to continue to deliver operational efficiencies and our expenses grow faster than our 
revenues, our operating margins, profitability and overall financial condition may be materially adversely impacted.

Our exposure to exchange rate fluctuations could adversely affect our results of operations.

Our contracts with clients are sometimes denominated in currencies other than the currency in which we incur expenses related 
to such contracts. Where expenses are incurred in currencies other than those in which contracts are priced, fluctuations in the 
relative value of those currencies could have a material adverse effect on our results of operations.

In addition, we are also subject to translation exposures as our consolidated financial results are presented in U.S. dollars, while 
the local results of certain of our subsidiaries are prepared in currencies other than U.S. dollars, including, amongst others, the 
pound sterling and the euro. Accordingly, changes in exchange rates between the U.S. dollar and those other currencies will affect 
the translation of subsidiary companies' financial results into U.S. dollars in reporting our consolidated financial results.

Our effective tax rate may fluctuate from quarter-to-quarter, which may adversely affect our results of operations.

Our quarterly effective tax rate has depended and will continue to depend on the geographic distribution of our taxable earnings 
amongst the multiple tax jurisdictions in which we operate and the tax law in those jurisdictions. Changes in the geographic mix 
of our results of operations amongst these jurisdictions may have a significant impact on our effective tax rate from quarter to 
quarter. Changes in tax law in one or more jurisdictions could also have a significant impact on our tax rate and results. In addition, 
as we operate in multiple tax jurisdictions, we may be subject to audits in certain jurisdictions. These audits may involve complex 
issues which could require an extended period of time for resolution. The resolution of audit issues may lead to differences, 
additional taxes, fines or penalties which could have a material adverse impact on our effective tax rate and our financial condition 
and results.

Our unsatisfied performance obligation (assessment of the realizable value of contracted awards) may not convert to revenue 
and the rate of conversion may slow.

Our remaining unsatisfied performance obligation is that element of contracted awards that has not yet converted to revenue. This 
value is not necessarily a meaningful predictor of future results, due to the potential for the cancellation or delay of projects 
included in the backlog.  No assurances can be given that we will be able to realize this backlog in full as revenue. A failure to 
realize these contracted awards could have a material adverse impact on our results of operations. In addition, as the length and 
complexity of projects increases, the rate at which contracted awards convert to revenue may be slower than in the past. A significant 
reduction in the rate of conversion could have a material impact on our results of operations.

The Company is exposed to various risks in relation to our cash and cash equivalents and short term investments.

The Company’s treasury function manages our available cash resources and invests significant cash balances in various financial 
institutions to try to ensure optimum returns for our surplus cash balances. These balances are classified as cash and cash equivalents 
or short term investments depending on the maturity of the related investment. Cash and cash equivalents comprise cash and highly 
liquid  investments  with  maturities  of  three  months  or  less. Short  term  investments  comprise  highly  liquid  investments  with 
maturities of greater than three months and minimum “A-” rated fixed and floating rate securities.

10

 
 
 
Given the global nature of our business, we are exposed to various risks in relation to these balances including liquidity risk, credit 
risk associated with the counterparties with whom we invest, interest rate risk on floating rate securities, sovereign risk (our 
principle sovereign risk relates to investments in U.S. Treasury funds) and other factors.

Although we have not recognized any significant losses to date on our cash and cash equivalents or short term investments, any 
significant declines in their market values could have a material adverse effect on our financial position and operating results.

Changes in accounting standards may adversely affect our financial statements 
.

We prepare our financial statements in accordance with generally accepted accounting principles in the United States of America 
('US GAAP') which is revised on an on-going basis by the authoritative bodies. It is possible that future accounting standard 
changes, may require additional changes to the accounting treatment that we apply in preparation of our financial statements.  
These changes may also require significant changes to our reporting systems. We applied ASC 606 - 'Revenue from contracts with 
customers' with effect from January 1, 2018. Under this new standard, the Company is required to recognize revenue in respect 
of our clinical trial services on a percentage of completion basis. The change in revenue recognition requires significant estimates 
of project costs that will need to be updated and adjusted on a regular basis. These updates may result in unexpected variability 
in the timing of recognition of revenue and therefore in our operating results. Application of ASC 842 - 'Leases' will result in the 
recognition of a lease liability and right-of-use asset on the Consolidated Balance Sheet at December 31, 2019. See Item 5 for our 
assessment of the impact of application.   

Risk Related to Political, Legal or Regulatory Environment

We may lose business opportunities as a result of health care reform and the expansion of managed care organizations.

Numerous governments, including the U.S. government have undertaken efforts to control growing health care costs through 
legislation, regulation and voluntary agreements with medical care providers and drug companies. If these efforts are successful, 
pharmaceutical,  biotechnology  and  medical  device  companies  may  react  by  spending  less  on  research  and  development  and 
therefore this could have a material adverse effect on our business.

In addition to health care reform proposals, the expansion of managed care organizations in the health care market may result in 
reduced spending on research and development. Managed care organizations' efforts to cut costs by limiting expenditures on 
pharmaceuticals and medical devices could result in pharmaceutical, biotechnology and medical device companies spending less 
on research and development. If this were to occur, we would have fewer business opportunities and our revenues could decrease, 
possibly materially.

Healthcare reform legislation, other changes in the healthcare industry and in healthcare spending could adversely affect our 
business model, financial condition or results of operations.

Our results of operations and financial conditions could be affected by changes in healthcare spending and policy.  The healthcare 
industry is subject to changing political, regulatory and other influences.  It is possible that legislation will be introduced and 
passed in the United States repealing, modifying or invalidating the current healthcare reform legislation, in whole or in part, and 
signed  into  law.  Because  of  the  continued  uncertainty  about  the  implementation  of  the  current  healthcare  reform  legislation, 
including the potential for further legal challenges or repeal of that legislation, we cannot quantify or predict with any certainty 
the likely impact of the current healthcare reform legislation or its repeal on the health care sector, on our customers and ultimately 
on our financial condition or results of operations, in particular the outsourcing of costs by our customer base to CROs. 

We may lose business as a result of changes in the regulatory environment.

Various regulatory bodies throughout the world may enact legislation, rules and guidance which could introduce changes to the 
regulatory environment for drug development and research. The adoption and implementation of such legislation, rules and guidance 
is difficult to predict and therefore could have a material adverse effect on our business.

11

 
Failure to comply with the regulations and requirements of the U.S. Food and Drug Administration and other regulatory 
authorities could result in substantial penalties and/or loss of business.

The U.S. Food and Drug Administration, or "FDA", and other regulatory and government authorities and agencies inspect and 
audit us from time to time to ensure that we comply with their regulations and guidelines, including environmental and health and 
safety matters, and other requirements imposed in connection with the performance of government contracts.  We must comply 
with the applicable regulatory requirements governing the conduct of clinical trials and contracting with the government in all 
countries in which we operate. If we fail to comply with any of these requirements we could suffer some or all of:

• 

• 

• 

• 

• 

• 

• 

termination of or delay in any research;

disqualification of data;

denial of the right to conduct business;

criminal penalties;

other enforcement actions including debarment from government contracts;

loss of clients and/or business; and

litigation from clients and/or patients and/or regulatory authorities and/or other affected third parties, and resulting material 
penalties, damages and costs.

We are subject to political, regulatory, operational and legal risks associated with our international operations.   

We are one of a small group of organizations with the capability and expertise to conduct clinical trials on a global basis. We 
believe that this capability to provide our services globally in most major and developing pharmaceutical markets enhances our 
ability to compete for new business from large multinational pharmaceutical, biotechnology and medical device companies. We 
have expanded geographically in the past and intend to continue expanding in regions that have the potential to increase our client 
base or increase our investigator and patient populations. We expect that revenues earned in emerging markets will continue to 
account for an increasing portion of our total revenues. However, emerging market operations may present several risks, including 
civil disturbances, health concerns, cultural differences such as employment, regulatory and business practices, compliance with 
economic sanctions, laws and regulations, volatility in gross domestic product, economic and governmental instability, the potential 
for nationalization of private assets and the imposition of exchange controls. In addition, operating globally means the Company 
faces the challenges associated with coordinating its services across different countries, time zones and cultures.

Changes in the political and regulatory environment in the international markets in which we operate such as price or exchange 
controls could impact our revenue and profitability and could lead to penalties, sanctions and reputational damages if we are not 
compliant with those regulations. Political uncertainty and a lack of institutional continuity in some of the emerging, developing 
or other countries in which we operate could affect the orderly operation of markets in these economies. In addition, in countries 
with a large and complicated structure of government and administration, national, regional, local and other governmental bodies 
may issue inconsistent decisions and opinions that could increase our cost of regulatory compliance and/or have a material adverse 
effect on our business.

On June 23, 2016, the United Kingdom, or U.K., held a referendum, referred to as “Brexit”, in which voters approved an exit from 
the European Union (E.U). As a result of the referendum, the British government continues to negotiate the terms of the U.K.’s 
future relationship with the E.U. The terms of the exit continue to be unknown however it is possible that there will be greater 
restrictions on trade and the transfer of goods and other items (including lab samples) between the U.K. and E.U. countries and 
increased regulatory complexities. At present, these changes are not expected to significantly affect our operations or financial 
results. Approximately 3% of our revenue is billed in Sterling. We currently employ approximately 700 people in the UK. The 
announcement of Brexit and continued uncertainty around the terms of exit is causing volatility in global stock markets and 
exchange rates. The fluctuation of currency exchange rates may expose us to gains and losses on non U.S. currency transactions.   

Uncertainty of the legal environment in some emerging countries could also limit our ability to enforce our rights. In certain 
emerging and developing countries we enjoy less comprehensive protection for some of our rights, including intellectual property 
rights, which could undermine our competitive position.

If any of the above risks or similar risks associated with our international operations were to materialize, our results of operations 
and financial condition could be materially adversely affected.

12

 
 
We operate in many different jurisdictions and we could be adversely affected by violations of the Foreign Corrupt Practices 
Act of 1977 (FCPA), UK Bribery Act of 2010 and similar anti-corruption laws in other jurisdictions.

The  FCPA,  UK  Bribery  Act  of  2010  and  similar  anti-corruption  laws  in  other  jurisdictions  prohibit  companies  and  their 
intermediaries from making improper payments for the purpose of obtaining or retaining business. In addition, the FCPA imposes 
certain books, records and accounting control obligations on public companies and other issuers. Our internal policies mandate 
compliance with these anti-corruption laws. We operate in many jurisdictions that have experienced corruption to some degree 
and in certain circumstances, anti-corruption laws have appeared to conflict with local customs and practices. Despite our training 
and compliance programs, we cannot assure that our internal control policies and procedures will protect us from acts in violation 
of anticorruption laws committed by persons associated with us and our continued expansion, including in developing countries, 
could increase such risk in the future. Violations of the FCPA, the U.K. Anti-Bribery Act of 2010 or other similar anti-corruption 
laws in other jurisdictions, or even allegations of such violations, could disrupt our business and result in a material adverse effect 
on our financial condition, results of operations, cash flows and reputation. For example, violations of anti-corruption laws can 
result in restatements of, or irregularities in, our financial statements as well as severe criminal or civil sanctions. In some cases, 
companies that violate the FCPA might be debarred by the U.S. government and/or lose their U.S. export privileges. In addition, 
U.S. or other governments may seek to hold us liable for successor liability FCPA violations or violations of other anticorruption 
laws committed by companies that we acquire or in which we invest. Changes in anti-corruption laws or enforcement priorities 
could also result in increased compliance requirements and related costs which could materially adversely affect our business, 
financial condition, results of operations and cash flows.

Current and proposed laws and regulations regarding the protection of personal data could result in increased risks of liability 
or increased costs to us or could limit our service offerings.

The confidentiality, collection, use and disclosure of personal data, including clinical trial patient-specific information, is subject 
to governmental regulation generally in the country that the personal data was collected or used. For example, United States federal 
regulations under the Health Insurance Portability and Accountability Act of 1996, or HIPAA, and as amended in 2014 by the 
Health Information Technology for Economic and Clinical Health (“HITECH”) Act, require individuals’ written authorization, in 
addition to any required informed consent, before Protected Health Information may be used for research. Such regulations specify 
standards for de-identifications and for limited data sets. We are both directly and indirectly affected by the privacy provisions 
surrounding individual authorizations because many investigators with whom we are involved in clinical trials are directly subject 
to them as a HIPAA “covered entity” and because we obtain identifiable health information from third parties that are subject to 
such regulations. As there are some instances where we are a HIPAA “business associate” of a “covered entity”, we can also be 
directly liable for mishandling protected health information. Under HIPAA’s enforcement scheme, we can be subject to up to $1.5 
million in annual civil penalties for each HIPAA violation.

The European data protection framework was significantly revised in 2018 with the coming into force of the General Data Protection 
Regulation ('GDPR') containing new provisions specifically directed at the processing of health information, sanctions of up to 
4%  of  worldwide  gross  revenue  and  extra-territoriality  measures  intended  to  bring  non-EU  companies  under  the  proposed 
regulation. Post GDPR implementation we are receiving increased volumes and breadth of data protection/privacy queries from 
both sponsors and strategic alliance partners and anticipate that this will continue. 

For the regulators in the European Union, or EU, personal data includes any information that relates to an identified or identifiable 
natural person with health information carrying special obligations, including obtaining the explicit consent from the individual 
for collection, use or disclosure of the information. EU regulations also apply to the personal data of EU data subjects traveling 
or living outside the EU. In addition, we are subject to EU rules with respect to cross-border transfers of such data out of the EU. 
The United States, the EU and its member states and other countries where we have operations, such as Japan, South Korea, 
Malaysia, the Philippines, Russia and Singapore, continue to issue new privacy and data protection rules and regulations that relate 
to  personal  data  and  health  information.  Failure  to  comply  with  certain  certification/registration  and  annual  re-certification/
registration provisions associated with these data protection and privacy regulations and rules in various jurisdictions, or to resolve 
any serious privacy complaints, could subject us to regulatory sanctions, criminal prosecution or civil liability. Federal, state and 
foreign governments are contemplating or have proposed or adopted additional legislation governing the collection, possession, 
use or dissemination of personal data, such as personal health information and personal financial data as well as security breach 
notification rules for loss or theft of such data. Additional legislation or regulation of this type might, among other things, require 
us to implement new security measures and processes or bring within the legislation or regulation de-identified health or other 
personal data, each of which may require substantial expenditures or limit our ability to offer some of our services. Additionally, 
if we violate applicable laws, regulations or duties relating to the use, privacy or security of personal data, we could be subject to 
civil liability or criminal prosecution, be forced to alter our business practices or suffer reputational harm. 

13

The failure to comply with our government contracts or applicable laws and regulations could result in, among other things, 
fines or other liabilities, and changes in procurement regulations could adversely impact our business, results of operations 
or cash flows.

Revenues from our government customers are derived from sales to federal, state and local governmental departments and agencies 
through  various  contracts.  Sales  to  public  segment  customers  are  highly  regulated.  Noncompliance  with  contract  provisions, 
government procurement regulations or other applicable laws or regulations (including but not limited to the False Claims Act) 
could  result  in  civil,  criminal  and  administrative  liability,  including  substantial  monetary  fines  or  damages,  termination  of 
government contracts or other public segment customer contracts, and suspension, debarment or ineligibility from doing business 
with the government and other customers in the public segment. In addition, generally contracts in the public segment are terminable 
at any time for convenience of the contracting agency or upon default. The effect of any of these possible actions by any governmental 
department or agency could adversely affect our business, results of operations or cash flows. In addition, the adoption of new or 
modified procurement regulations and other requirements may increase our compliance costs and reduce our gross margins, which 
could have a negative effect on our business, results of operations or cash flows.

Liability claims brought against us could result in payment of substantial damages, costs and liabilities and decrease our 
profitability.

Customer Claims
If we breach the terms of an agreement with a customer (for example if we fail to comply with the agreement, all applicable 
regulations or Good Clinical Practice) this could result in claims against us for substantial damages which could have a material 
adverse effect on our business. As we are a “people business” in that we provide staff to provide our services in hospitals and other 
sites, there is a risk that our management, quality and control structures fail to quickly detect a failure by one or more employees 
or contractors to comply with all applicable regulations and Good Clinical Practice and our internal requirements and standard 
operating procedures thereby exposing us to the risk of claims by customers.

Claims relating to Investigators
We contract with physicians who serve as investigators in conducting clinical trials to test new drugs on their patients. This testing 
creates the risk of liability for personal injury to or death of the patients. Although investigators are generally required by law to 
maintain their own liability insurance, we could be named in lawsuits and incur expenses arising from any professional malpractice 
or other actions brought against the investigators with whom we contract.

Indemnification from Customers
Indemnifications provided by our customers  against the risk of liability for personal injury to or death of the patients arising from 
a study drug vary from customer to customer and from trial to trial and may not be sufficient in scope or amount, or our customer  
may not have the financial ability to fulfill their indemnification obligations. Furthermore, we would be liable for our own negligence 
and negligence of our employees which could lead to litigation from customers or action or enforcement by regulatory authorities.

Insurance
We maintain what we believe is an appropriate level of worldwide Professional Liability/Error and Omissions Insurance. In the 
future we may be unable to maintain or continue our current insurance coverage on the same or similar terms. If we are liable for 
a claim or settlement that is beyond the level of insurance coverage, we may be responsible for paying all or part of any award or 
settlement amount. Also, the insurance policies contain exclusions which mean that the policy will not respond or provide cover 
in certain circumstances.

Claims to Date
To date, we have not been subject to any liability claims that are expected to have a material effect on our business; however, there 
can be no assurance that we will not become subject to such claims in the future or that such claims will not have a material effect 
on our business.

Risk Related to Our Indebtedness

We have incurred debt, which could impair our flexibility and access to capital and adversely affect our financial position.

As of December 31, 2018 and December 31, 2017, we had an outstanding principal amount of indebtedness of $350 million under 
our $350 million Note Purchase and Guarantee Agreement or ‘Senior Notes’ that we entered into on December 15, 2015.  The 
Senior Notes will mature on December 15, 2020. We also have up to $150 million of additional borrowing capacity available 
under the Revolving Credit Facility which was entered into with Citibank, JP Morgan, Santander, HSBC Bank and Morgan Stanley 
International on March 12, 2018. No amounts were drawn under the Revolving Credit Facility as of December 31, 2018. This 
14

 
facility bears interest at LIBOR plus a margin. We are monitoring the phasing out of LIBOR currently scheduled for 2021. We 
have engaged with our lenders on the implications of the change. In the absence of an agreed new rate, documents continue to be 
negotiated using LIBOR. We will continue to engage with our lenders in respect of the requirement for a new rate and seek an 
amendment letter at that point. 

The cost and availability of credit are subject to changes in the global or regional economic environment. If conditions in the major 
credit  markets  deteriorate  our  ability  to  obtain  debt  financing  on  favorable  terms  may  be  negatively  affected. We  may  incur 
additional debt in the future. Our debt could have significant adverse consequences, including to:

• 

• 

• 

• 

• 

• 

• 

• 

• 

limit our ability to borrow additional funds for working capital, capital expenditures, acquisitions or other general business 
purposes;

limit our ability to use our cash flow or obtain additional financing for future working capital, capital expenditures, 
acquisitions or other general business purposes;

require us to use all or a portion of our cash flow from operations to make debt service payments;

require us to sell certain assets;

restrict us from making strategic investments, including acquisitions or cause us to make non-strategic divestitures;

place us at a competitive disadvantage compared to our competitors that have less debt;

cause us to incur substantial fees from time to time in connection with debt amendments or refinancing;

limit our flexibility to plan for, or react to, changes in our business and industry; and

increase our vulnerability to the impact of adverse economic and industry conditions.

Our ability to meet our debt service obligations will depend on our future performance, which will be subject to financial, business 
and other factors affecting our operations, many of which are beyond our control. If we do not have sufficient funds to meet our 
debt service obligations, we may be required to refinance or restructure all or part of our existing debt, sell assets, borrow more 
money or sell securities, none of which we can be assured that we would be able to do in a timely manner, or at all.

In addition, a failure to comply with the covenants under our indebtedness could result in an event of default under such indebtedness.  
In the event of an acceleration of amounts due under our existing indebtedness as a result of an event of default, we may not have 
sufficient funds or may be unable to arrange for additional financing to repay our indebtedness or to make any required accelerated 
payments.

In addition, we are required, under the terms of the Senior Notes, to offer to purchase all of the outstanding Senior Notes if we 
experience a change of control.  Similar requirements exist in the Revolving Credit Facility. These provisions may delay or prevent 
a change in control that our stockholders may consider desirable.

Covenants  in  our  credit  agreements  may  restrict  our  business  and  operations  and  our  financial  condition  and  results  of 
operations could be adversely affected if we do not comply with those covenants.

The Senior Notes and the Revolving Credit Facility credit agreements include certain customary covenants that limit our ability 
to, amongst other things, subject to certain exceptions:

• 

• 

• 

• 

incur or assume liens or additional debt;

dispose of assets;

engage in mergers or reorganizations; or

enter into certain types of transactions with affiliates.

The Senior Notes agreement also includes certain financial covenants that require us to comply with a consolidated leverage ratio, 
a minimum EBITDA to consolidated net interest charge ratio and a maximum amount of priority debt, each of which are defined 
15

in the Note Purchase and Guarantee Agreement. Our ability to comply with these financial covenants may be affected by events 
beyond our control.

These covenants may limit our operating and financial flexibility and limit our ability to respond to changes in our business or 
competitive activities.

In the event that we fail to pay principal or interest when due on the Senior Notes, or as a result of a material breach of any 
representation, warranty or covenant or any other event of default then all outstanding amounts could become immediately due 
and payable. If, in such a circumstance, any of the holders of the Senior Notes, accelerate the repayment of such indebtedness, 
there can be no assurance that we will have sufficient assets to repay our indebtedness.

Interest rate fluctuations may materially adversely affect our results of operations and financial condition in the event that the 
Company draws down on either Revolving Credit Facility or in respect of any future issuances of debt.

The interest rate in respect of the Senior Notes is fixed at 3.64% for the five year term of the agreement. The Revolving Credit 
Facility bears interest at LIBOR plus a margin. There were no amounts drawn on either Revolving Credit Facility or the short 
term uncommitted facility at December 31, 2018. The Company is therefore subject to interest rate volatility in respect of any 
future draw down on the Revolving Credit Facility or in respect of any future issuances of debt. 

Risk Related to Our Common Stock 

Volatility in the market price of our common stock could lead to losses by investors.

The market price of our common stock has experienced volatility in the past and may experience volatility in the future which 
could lead to losses for investors. Factors impacting volatility in the market price of our common stock include, amongst others:

Industry Overview

The CRO industry provides independent product development solutions and services for the pharmaceutical, biotechnology and 
medical device industries. Companies in these industries outsource services to CROs in order to manage the drug and device 
development process more efficiently and to bring both patent-protected bio-similars and medical devices to market faster to 
enhance patient well-being and maximize their return on investment. The CRO industry has evolved since the 1970s from a small 
number of companies that provided limited clinical development services to a larger number of CROs that offer a range of services 
that  encompass  the  entire  research  and  development  process,  including  pre-clinical  development,  clinical  trials  management, 
clinical data management, study design, biostatistical analyses, post market surveillance, regulatory affairs, central laboratory and 
market  access  services.  CROs  are  required  to  provide  services  in  accordance  with  good  clinical  and  laboratory  practices,  as 
governed by the applicable regulatory authorities.

The CRO industry is highly fragmented, consisting of several hundred small, limited-service providers, medium sized CROs and 
a small number of large CROs with global operations. Although there are few barriers to entry for small, specialist service providers, 
we believe there are significant barriers to becoming a CRO with global capabilities and expertise. These barriers include the 
infrastructure and experience necessary to serve the global demands of clients (sponsors), the ability to recruit sites and patients 
globally, the simultaneous management of complex clinical trials, the ability to offer customers a variety of delivery models, broad 
therapeutic expertise and the development and maintenance of the complex information technology systems required to integrate 
these capabilities. In recent years, the CRO industry has experienced consolidation, resulting in the emergence of a select group 
of CROs that have the capital, technical resources, integrated global capabilities, data and expertise to manage the development 
programs of pharmaceutical, biotechnology and medical device companies. We believe that large and medium sized pharmaceutical 
companies are selecting a limited number of CRO service providers with which they deal rather than utilizing many, in order to 
form strategic partnerships with global CROs in an effort to drive incremental development efficiencies and leverage the scientific 
and medical expertise. We believe that this trend will continue to concentrate the market share among the larger CROs with a track 
record of quality, speed, flexibility, responsiveness, global capabilities and access to patients and overall development experience 
and expertise.

New Drug Development – Ethical Pharmaceuticals and Biologics - An Overview

Before a new drug or biologic may be marketed, it must undergo extensive testing and regulatory review in order to determine 
that it is safe and effective. The following discussion primarily relates to the FDA approval process for such products. Similar 
procedures must be followed for product development with other global regulatory agencies. The stages of this development 
process are as follows: 

Preclinical Research “In vitro” (test tube) and animal studies must be conducted in accordance with applicable regulations to 
establish the relative toxicity of the drug over a wide range of doses and to detect any potential to cause birth defects, affect vital 
organs, cause mutations or cancer. Many of these tests must be performed before a new investigational therapy can progress into 
human studies. If results warrant continuing development of the drug or biologic, the sponsor or owner of the asset will file for 
an Investigational New Drug Application, or IND, which must be approved by the FDA before starting the proposed clinical trials.  
However, preclinical studies will continue to be conducted in parallel with the clinical trials, some of which can take up to 3 years 
to complete.

Clinical Trials (approximately 3.5 to 7 years).

Exploratory Development

Phase I (approximately 6 months to 1 year) consists of basic safety and tolerability testing in small numbers of human subjects, 
initially in healthy volunteers, and includes studies which may show the drug is having an effect on the body, if it is safe, how it 
is affected by other drugs, where it goes in the body, how long it remains active and how it is broken down by and eliminated from 
the body. After single and multiple dose studies have been conducted, the asset can progress into Phase II, however, Phase I studies 
will continue to be done to help support the development of the asset in new populations such as children or the elderly.

Phase II (approximately 2 to 3 years) includes basic efficacy and dose-range testing in a limited patient population (usually) 100 
to 200 patients to help provide preliminary safety and evidence that the drug is likely to be effective in the target disease. If the 
Phase II results are satisfactory the sponsor may decide to proceed to Phase III studies.

18

Confirmatory Development

Phase III (2 years or greater) consists of efficacy and safety studies in several hundred to a few thousand patients at multiple 
investigational sites (hospitals and clinics), often in multiple geographies. These studies look to definitively confirm the overall 
benefit of the agent and, if successful, will be used to provide the labelling claims for the drug. These studies can be placebo-
controlled trials, in which the new drug is compared with a “sugar pill”, or studies comparing the new drug with one or more drugs 
with established safety and efficacy profiles in the same therapeutic indication.

FDA approval, through submission of an investigational new drug (IND) application, is necessary for all clinical trials, regardless 
of the phase of development. In addition, parallel independent committee approval is also required.

NDA or BLA Preparation and Submission. Upon completion of Phase III trials, the sponsor assembles the statistically analyzed 
data from all phases of development into a single large submission along with the Chemistry, Manufacturing and Controls (CMC) 
and preclinical data and the proposed labeling into the New Drug Application (NDA), or Biologics License Application (BLA) 
and submits them for assessment and approval by the relevant division of the FDA.

Expanded Access Programs (EAPs), Sometimes a study drug may continue to be provided to subjects after completion of a 
clinical trial, also called compassionate use. EAPs refer to the regulated use of a study drug outside of a clinical trial by patients 
with serious or life-threatening conditions where there is no alternative therapy available. In this context the FDA may allow the 
sponsor to make the study drug available to a larger number of patients for treatment use. 

FDA Review and Approval of NDA or BLA (1 to 1.5 years). Data from all phases of development is scrutinized to confirm that 
the applicant company has complied with all applicable regulations and that the benefit to risk ratio for the drug or biologic is 
positive for the specific use (or “indication”) under study. The FDA may refuse to accept the NDA or BLA if the application has 
administrative or content criteria which do not meet FDA standards. The FDA may also deny approval of the drug or biologic 
product if applicable regulatory requirements are not satisfied, if the drug has not adequately shown to be effective or there are 
safety concerns. Often a company will be required to conduct specific studies after the approval of a drug. These are called post 
approval commitments.

Post-Market Surveillance, Phase IV Studies and Health Outcomes. Once approved by the FDA, the FDA requires the drug or 
biologic license holder to collect and periodically report to the FDA additional safety (and perhaps efficacy) data on the drug or 
biologic for as long as the license holder markets it (post-market surveillance, including pharmacovigilance). If the product is 
marketed outside the U.S., these reports must include data from all countries in which the drug is sold. Additional studies (Phase 
III and Phase IV) may be undertaken after initial approval to find new uses for the drug, to test new dosage formulations, or to 
confirm selected non-clinical benefits, e.g., increased cost-effectiveness or improved quality of life. Additionally, FDA and other 
regulatory agencies are requiring license holders of drugs or biologics to prepare risk management plans which are aimed at 
assessing areas of product risk and actively managing such risks throughout the product lifecycle.  

Key Trends Affecting the CRO Industry

CROs derive substantially all of their revenue from the research and development expenditures of pharmaceutical, biotechnology 
and medical device companies. Based on investment analyst research and our internal estimates, we estimate that development 
expenditures outsourced by pharmaceutical and biotechnology companies worldwide in 2018 was approximately $33 billion. We 
believe that the following trends create further growth opportunities for global CROs, although there is no assurance that growth 
will materialize.

Continued Innovation and Development of Enabling Technologies

Innovation Driving New Drug Development Activity. 

New technologies together with improved understanding of disease pathology (driven by scientific advances such as the mapping 
of the human genome) have increased the number of new drug candidates being investigated in early development. This has greatly 
broadened the number of biological mechanisms being targeted which increasingly include rare/orphan diseases that currently 
have no effective treatments. 

These developments should lead to increased activity in both Preclinical and Phase I development and in turn lead to more treatments 
in Phase II-III clinical trials. As the number of trials that need to be performed increases and these trials become focused in 
indications where finding suitable patients is increasingly challenging, we believe that drug developers will increasingly rely on 

19

 
CROs to manage these trials to leverage their global expertise and to continue to focus their own competences on drug discovery 
and sales and marketing.

New Technology Enabling More Efficient Development.

Technology innovation is playing an increasing important role in helping to support more efficient drug development. The larger 
CROs have been at the forefront of this innovation developing technology solutions that support the integration of trial data across 
multiple systems; data repositories that enable sponsors to get real time clinical insights on their drugs performance and tools that 
support better trial designs and operation. These include;

• 

• 

adaptive trial software, such as ICON’s ADDPLAN software, which is part of the ICONIK Informatics Hub and is the 
market leader for design, simulation and analysis of adaptive clinical trials spanning Phases I to IV. ADDPLAN has been 
used by regulatory agencies (FDA, EMA (Europe) and PMDA (Japan)) to assess adaptive trial submissions;

FLEX ADVANTAGE  is  our  interactive  response  technology  platform  (accessible  through  the  web  and  web-enabled 
mobile devices) for managing patient randomization, investigator sites and clinical suppliers;  

•  Data analysis from ICONIK Informatics Hub allows us to enhance the design and delivery of our projects, through 

stronger engagement with investigators and patients;

• 

• 

PDx-Pop software is a graphical interface for NONMEM which has its own automation methodology which expedites 
the iterative process of population pharmacokinetic modeling and analysis;

IMRA is a web based laboratory review application that allows global access to the latest laboratory data on a study - it 
facilitates detailed analysis of any trends, signals, alerts or patient specific data on a real-time basis.  

The emergence of M-health technologies that build on the global prevalence of mobile and digital technologies also have an 
influence on drug development. It is now possible to capture health data using mobile devices and wearables. This enables sponsors 
to  gather  new  clinical  and  “real-world”  patient  insights  and  will  also  be  used  to  enhance  patient  engagement  and  adherence 
throughout the development process. As these devices mature it will also be possible to complete more “virtual trials” based on 
remote monitoring of patients in their home environment which may drive further efficiencies in the trial process.

Social media is also becoming an important platform for life sciences companies to strengthen patient engagement programs and 
collaborate with other stakeholders in the health care system. Many sufferers of specific diseases are forming patient groups and 
actively collaborating using social media. These groups represent an important potential source of patients for new clinical studies 
but can also provide valuable insights into effectiveness and safety of new treatments. 

As the influence of technology on drug development grows, it broadens the potential number of partners that CROs will work 
with in the future. 

Expanded use of new patient data sources.  

Pharmaceutical companies are looking to access a variety of new health care data sources containing medical and prescribing 
records to help improve development programs and to get better evidence of the value their treatments are bringing to patients 
once they are launched in the market. The larger global CROs have significant data management experience which can be leveraged 
to support these efforts and have invested in analytics capabilities to help deliver better insights for customers during the product 
lifecycle. Global CROs are also forging collaborations to access specific data sets that can provide further patient insights to 
support better matching of patients to the clinical trial process. 

Improving Productivity and Operating Efficiencies 

Continuing focus on Productivity within Research and Development Programs.

Pharmaceutical and biotechnology companies continue to seek ways to improve the productivity of their development efforts and 
increasingly see the use of CROs as a strategic component of these efforts. They are leveraging the expertise with CROs to help 
identify the most promising drug candidates in early development and discontinue developing those that have safety issues, limited 
efficacy  or  that  will  have  significant  reimbursement  challenges. These  companies  are  also  initiating  programs  to  drive  more 
efficiency in their development programs. One example of this has been the efforts to achieve a more seamless transition across 
development phases, particularly Phase I-III. In parallel, regulatory initiatives such as the 21st Century Cures Act and the emergence 
20

of clinical trial techniques such as adaptive trial design and risk based clinical trial monitoring are enhancing development, allowing 
effective treatments to get to patients quicker at reduced development costs. 

Cost Containment Pressures. 

Over the past several years, drug companies have sought more efficient ways of conducting business due to margin pressures 
stemming from patent expirations, greater acceptance of generic drugs, pricing pressures caused by the impact of managed care, 
purchasing  alliances  and  regulatory  consideration  of  the  economic  benefit  of  new  drugs.  Consequently,  drug  companies  are 
centralizing research and development, streamlining their internal structures and outsourcing certain functions to CROs, thereby 
converting previously fixed costs to variable costs. Larger companies (and more recently medium sized companies) are actively 
entering strategic partnerships with a limited number of CROs in an effort to drive increased efficiencies. The CRO industry and 
in particular large CROs with global capabilities, considerable scientific knowledge and expertise are often able to perform the 
needed services with greater focus and at a lower cost than the client could perform internally, although CRO companies themselves 
are facing increased cost containment pressures as drug companies seek to further reduce their cost base.

Global trends influencing the CRO industry

Pressure to Accelerate Time to Markets and Globalization of the Marketplace. 

Reducing product development time maximizes the client’s potential period of patent exclusivity, which in turn maximizes potential 
economic returns. We believe that clients are increasingly using CROs that have the appropriate expertise and innovation to improve 
the speed of product development to assist them in improving economic returns. In addition, applying for regulatory approval in 
multiple markets and for multiple indications simultaneously, rather than sequentially, reduces product development time and 
thereby maximizes economic returns. We believe that CROs with global capabilities, considerable knowledge and experience in 
a broad range of therapeutic areas are key resources to support a global regulatory approval strategy. Alongside this, the increasing 
need to access pools of new patients is leading to the conduct of clinical trials in new “emerging regions” such as Eastern Europe, 
Latin America, Asia-Pacific and South America. We believe that having access to both traditional and emerging clinical research 
markets gives global CROs a competitive advantage.

Growth within the Biotechnology Sector.

The nature of the drugs being developed is continuing to change. Biotechnology is enabling the development of targeted drugs 
with diagnostic tests to determine whether a drug will be effective given a patient’s genomic profile. An increasing proportion of 
research and development (“R&D”) expenditure is being spent on the development of highly technical drugs to treat very specific 
therapeutic areas in areas of unmet medical need. Much of this discovery expertise is found in biotechnology firms. We believe 
that it is to these organizations that the large pharmaceutical companies will look for an increasing proportion of their new drug 
pipelines. Whether it is through licensing agreements, joint ventures or equity investment, we believe we may see the emergence 
of more strategic relationships between small discovery firms and the larger pharmaceutical groups. As the majority of these 
biotechnology companies do not have a clinical development infrastructure, we believe that the services offered by CROs will 
continue to be in demand from such companies providing they have the necessary funding.

Increasing Number of Large Long-Term Studies and an increasing requirement to show the Economic Value of New Treatments.

We believe that to establish competitive claims and demonstrate product value, to obtain reimbursement authorization from bodies 
such as the National Institute for Health and Clinical Excellence in the UK, and to encourage drug prescription by physicians in 
some large and competitive categories, more clients need to conduct outcome studies to demonstrate, for example, that mortality 
rates are reduced by certain drugs. To verify such outcomes, very large patient numbers are required and they must be monitored 
over long time periods. We believe that as these types of studies increase there will be a commensurate increase in demand for 
the services of CROs who have the ability to quickly assemble large patient populations, globally if necessary, and manage this 
complex process throughout its duration.

The rising costs of health care in most developed countries also means there is an increasing pressure to show that new medical 
treatments are more cost effective and deliver better patient outcomes than existing treatments regimes. This also means that 
sponsors need to increasingly generate outcomes data both as part of the product approval submissions and as part of post-approval 
research programs. This is creating opportunities for CROs who can offer support in developing and interpreting this data.

21

A Focus on Long-term Product Safety.

The clinical trial approval process can only detect major and common adverse side effects of drugs; less common but no less 
serious side effects may only become apparent after many years of use. As a result, there is an increase in the number of drugs 
given “conditional approvals” where further ‘post-approval’ studies are being mandated. In addition, prudent sponsors undertake 
similar studies to detect early warning signs of any potential problems with their products. Such studies may take the form of 
prospective long-term safety studies, simpler observational studies or registries where patients meeting specific criteria for disease 
or drug use are followed for long periods to detect any safety issues. CROs are well positioned to perform these studies on behalf 
of sponsors.  

Increasing Regulatory Demands. 

Regulatory agencies are requiring more data to support new drug approvals and are seeking more evidence that new drugs are 
safer and more effective than existing products. As a result, the complexity of clinical trials, the number of procedures required 
to be conducted in these trials and the size of regulatory submissions are driving the demand for services provided by CROs.

The ICON Strategy

ICON’s mission is to accelerate the development of drugs and devices that save lives and improve the quality of life. Our vision 
is to be the global CRO partner of choice in drug development by delivering best in class information, solutions and performance.

We have achieved strong growth since our foundation in 1990. The impact of the International Conference on Harmonization 
Good Clinical Practice, the resulting globalization of clinical research and the acceleration in the understanding of human and 
molecular biology which has led to many new treatment paths being explored were key catalysts of our early growth.

As our market has evolved, biopharmaceutical companies are tackling productivity challenges, increasing budget constraints and 
greater  demands  to  demonstrate  product  value;  all  of  which  are  placing  increased  pressure  on  their  revenues  and  levels  of 
profitability. However these trends have generally been positive for CROs, as increased outsourcing has been adopted by these 
companies as they seek to create greater efficiencies in their development processes, convert previously fixed costs to variable, 
and accelerate time to market for new treatments.

One consequence of the drive to accelerate time to market will be increased emphasis on making existing drug development phases 
more seamless, through the use of techniques such as adaptive trial designs to filter the most promising compounds and test these 
in parallel in several therapeutic indications or with other drug combinations.

Regulatory and reimbursement pressures will increase the emphasis on late stage (post marketing) research, while increasing 
requirements to demonstrate the economic value of new treatments. As a result, outcomes and comparative effectiveness research 
will most likely be required in order to secure on-going product reimbursement. Furthermore, we believe advances in molecular 
biology and genetics will drive further growth in innovation in the long term which in turn should create further growth opportunities 
for both biopharma companies and their outsource development partners.

We expect the increased adoption of outsourcing will be a core strategy of clients in the near term as they respond to the increased 
pressures on their revenues and profitability. Larger clients were the first to form strategic partnerships with global CROs in an 
effort  to  reduce  the  number  of  outsource  partners  with  whom  they  engage  and  to  reduce  inefficiencies  in  their  current  drug 
development models. More recently we have seen the increasing adoption of this partner model with mid-tier pharmaceutical and 
biotechnology firms as they also seek to drive development efficiencies. As outsourcing penetration increases, we believe clients 
may seek a greater level of integration of service offerings from CROs, although some will continue to purchase services on a 
stand-alone basis. Creating greater connectivity and “seamlessness” between our services and the sharing of “real-time” clinical, 
operational and “real world” data with clients will therefore become increasingly important for CROs. ICON will seek to benefit 
from this increased outsourcing by clients to grow our business by increasing market share with our existing client base and adding 
new clients within the Phase I-IV outsourced development services market; the aim being to ensure we will be considered for all 
major Phase I-IV projects.

Our strategy to achieve these objectives is focused on the following areas:

Partnerships, Customers and Markets

We continue to focus on expanding and deepening our partnerships with existing customers, while also developing new customer 
relationships.

22

Strategic client relationships will increasingly manifest themselves in many different forms. Many of these relationships will 
require innovative forms of collaboration across ICON service areas and departments and will therefore require increased flexibility 
to offer services on both a standalone functional basis and as part of a fully integrated service solution. To support this objective, 
we continue to evolve our collaboration and delivery models, invest in technology that will enable closer data integration across 
our service areas and enhance our project and program management capabilities.

We continue to enhance our capabilities through both organic service development and targeted acquisitions, to meet the evolving 
needs of both existing and new clients. In 2017 we acquired the Mapi Group, a leading Patient-Centered Health Outcomes Research 
and  Commercialization  company. This  acquisition  strengthened ICON’s  existing  Commercialization  and  Outcomes  Research 
business adding  significant  commercialization  presence,  analytics,  real  world  evidence  generation  and  strategic  regulatory 
expertise.  The  combined  organization  will  be  a  leader  for  real  world  evidence,  post  approval  research,  language  services, 
consultancy services supporting clinical outcomes assessments, pricing and market access and scientific communications.

We continue to target growth in under-penetrated CRO market segments, outsourcing penetration within Medical Device companies 
has lagged that of bio-pharma firms but is beginning to accelerate. EU Regulatory reform enacted in 2017 is a further catalyst to 
growth in this segment as it included stricter requirements to perform clinical evaluations and post sale surveillance. ICON is well 
positioned in this market having acquired strong device development capabilities in the acquisition of Aptiv Solutions in 2014. 
We continue to expand our presence in regions such as Asia-Pacific, in particular in China and Japan, building on our acquisition 
of Niphix, the Japanese subsidiary of Aptiv Solutions, in 2014 and BeijingWits Medical Limited, a leading Chinese CRO, in 2012.

Operational Excellence and Quality

We continue to enhance our operating processes and delivery models to gain competitive advantage.

Our proprietary ICONIK platform, which integrates clinical data across multiple systems allows us to access clinical and real 
world data to enhance protocol design, profile match patients to trials. It also facilitates collection of real-time data during the trial 
process enabling better decision making and project execution. The platform uses data and evidence based research to develop 
solutions that engage investigators and patients more effectively to improve patient recruitment and retention. 

ADDPLAN is part of the ICONIK Informatics Hub. The software provides industry leading statistical design, simulation and 
analysis for adaptive clinical trials, from phase I to IV and helps our customers identify the most promising drug candidates earlier 
in the development process and in parallel test these across several therapeutic indications and with other drug combinations.

Finding and engaging suitable patients to conduct clinical trials is one of the biggest issues facing drug development industry  
today. Less than 1% of the US population participates in clinical trials and the performance of investigative sites that do take part 
in research is uneven, hard to predict and many trials do not meet the initial recruitment goals. The current market challenge in 
patient enrollment creates an opportunity for ICON to differentiate its service offering and we are working to reduce patient 
recruitment times through enhanced site and investigator selection based on key performance metrics and through use of our 
proprietary Firecrest technology which is used to train and support sites during the development process. Our PMG site network 
alliances enhanced our ability to enroll patients onto the clinical studies we perform. We have also developed strategic alliances 
with investigator site groups and health care systems in all major global research markets. In partnership with others we are 
pioneering patient recruitment solutions that leverage cognitive computing to transform clinical trial matching and allow a data-
driven approach to deliver the right patients for trials.  

Quality project execution underpins all that we do and we have an ongoing focus on developing our people and processes to 
continue to enhance our service delivery. We are also deploying supporting technologies which we believe will enable faster and 
deeper insights into the quality of trial data.

We are focused on operational excellence across our support functions and we operate a global business support infrastructure 
across functions including finance, information technology, facilities, human resources and legal. This is enabling us to enhance 
the service levels across these support areas whilst driving down the costs of this service provision.

Talent, Leadership Development and Culture 

At the core of our strategy is our people. Within ICON we have highly qualified and experienced teams, the majority of whom 
have third level educational qualifications. The need to develop and retain this expertise and talent within the organization is 
fundamental in enabling us to be the global CRO partner of choice for our customers.  We have invested in creating an innovative 
learning  environment  delivered  through ICON’s  training  and  development  group,  who  have  formed  an  industry  leading 
collaboration with University College Dublin. This enables ICON to provide customized management and development programs 
23

for global employees. These programs are focused on leadership development for those people management roles and specific 
technical training in competencies that are core to our business, such as project and program management and clinical research 
associate development. We continue to invest to refine and develop these programs.

Within our training program we have also created a Clinical Research Academy and a unique Graduate Certificate in Clinical Trial 
Management which is enhancing the quality of graduate training in clinical research and increasing the pool of talent available to 
ICON that can support our customers’ drug development programs.

Our learning and development programs are complemented by advanced people development practices which incorporate rigorous, 
analytics based screening in the hiring process, global career frameworks, pay for performance aligned to our strategy, and on-
going talent review and succession planning.

Our leadership and talent programs contribute to the enhanced retention of our employees, better project deliverables for our 
customers and the enhanced financial performance of the business.

Our investment in people was reflected by our inclusion in 2018 for the second consecutive year, by Forbes in their list of the best 
employers in America. ICON was ranked the top CRO and amongst the top 10 employers in the Drugs and Biotechnology industry 
overall.

Enhance Capabilities & Expertise  

To meet the evolving needs of our clients we continue to enhance our capabilities through both organic service development and 
targeted acquisitions. During 2018, we continued to enhance our scientific and therapeutic expertise to support our customers in 
specific areas including Oncology, Orphan and Rare Diseases, CNS, Dermatology, Infectious Disease and Womens Health. 

We have continued to invest in building our capabilities in the gathering, analysis and application of real world patient data within 
both the clinical trial and post-trial observational study environments. Alongside expanding internal capabilities, we continue to 
develop innovative partnerships with providers of real world data including EHR4CR and Trinetx. During 2018, we signed an 
agreement with Intel to deploy the Intel® Pharma Analytics Platform for use in clinical trials. The Intel platform is an artificial 
intelligence solution that enables remote monitoring and continuous capture of clinical data from study subjects using sensors and 
wearable devices and can apply machine learning techniques to objectively measure symptoms and quantify the impact of new 
therapies.

We continued to enhance our site and patient recruitment capabilities during 2018 with the expansion of the PMG Research network 
through a partnership with the Du Page Medical Group. DuPage is the largest independent, multi-specialty physician group in the 
Chicagoland area with access to more than 700 physicians in over 50 clinical specialties ranging from primary to specialty care 
in areas such as cardiology and oncology. Through this agreement PMG assumed the research infrastructure at DuPage providing 
expanded investigator and patient access and bringing clinical research as a care option to the communities served. 

Applied Innovation

ICON is focused on applying innovation that can help our customers improve their development outcomes. We are focusing this 
innovation in three critical areas; improving clinical trial design and execution; faster and more predictable patient recruitment; 
and evolving clinical trials to be more patient centric which includes data collection and analysis directly from patient’s digital 
devices. Our approach to developing solutions to these challenges incorporates partnering with best in class technology providers 
but is also supported by a suite of differentiated ICON proprietary technologies.

Our ICONIK platform is a web-based information platform that facilitates the management, reporting, analysis and visualization 
of all data relating to drug development, and supports our risk based monitoring solution. This solution allows monitoring resources 
to be directed at specific sites based on real-time data analysis which can significantly reduce monitoring costs for clients.

Firecrest; ICON’s proprietary comprehensive site performance management system, is a web-based solution which enables accurate 
study  information,  including  protocol  information,  training  manuals  and  case  report  forms,  to  be  rolled  out  quickly  and 
simultaneously to investigative sites. It allows site behavior to be tracked to ensure training is understood, procedures are being 
followed and that timelines and study parameters are met. It can significantly reduce the number of data queries originated from 
investigator sites.

Our ADDPLAN software offers a leading statistical design, simulation and analysis software for adaptive clinical trials and helps 
our customers identify the most promising drug candidates earlier. ADDPLAN is used by FDA, EMA and Japan’s PMDA, as well 
24

as over fifty top pharmaceutical and medical device companies and academic researchers (see Information Systems on page 27 
for further information).

Alongside  the  application  of  these  technology  solutions  we  are  also  focused  on  innovation  through  the  redesign  and  where 
appropriate the automation of current clinical trial processes.

Sales and Marketing

Our marketing strategy is focused on building a differentiated brand position for ICON and supporting our business development 
efforts to develop and build relationships with pharmaceutical, biotechnology, medical device, and government and public health 
organizations. Our marketing activities are coordinated centrally to ensure a consistent and differentiated market positioning for 
ICON and to ensure all marketing efforts align to the overall strategic objectives of the business. Our business development teams 
are located throughout the Americas, Europe and Asia Pacific regions. Business development activities are carried out by account 
executives with assigned territories and global account directors supporting our large accounts. Specialized business development 
teams focus on growing each of our business areas. Collectively, our business development team, senior executives and project 
team leaders share responsibility for the maintenance of key client relationships. Our aim is to develop deeper relationships within 
our client base in order to gain repeat business and give us opportunities to penetrate into other therapeutic indications and adjacent 
service lines.

Competition

The CRO industry is fragmented, consisting of many small, niche service providers, a declining number of medium-sized providers 
and a smaller number of large CROs, including ICON, that are differentiated by the scale of their global operations, breadth of 
service portfolios and supporting technology infrastructure. The need to conduct complex research and access patients on a global 
basis is driving market share to these global CROs. When competing for large development programmes, ICON competes primarily 
with IQVIA, PAREXEL, Pharmaceutical Product Development ('PPD'), the Covance Drug Development business of LabCorp, 
PRA Health Sciences and Syneos Health. In some specific markets, for example biotech and mid-tier pharma, ICON may also 
compete against mid-tier CROs including Medpace.

CROs generally compete on the basis of previous product experience, the ability to recruit patients on a global basis, the depth of 
therapeutic and scientific expertise, the strength of project teams, price and increasingly on the ability to apply new innovation 
that can drive significant time and cost savings throughout the development process. An evolving area of competition is the need 
to provide services that can help generate the evidence of the economic value of new treatments that payers and regulators require. 
This requires access to new data sources which includes information to support the identification of suitable investigator sites and 
patient populations as well as data on the value delivered by new products following marketing approval. 

We believe that we compete favorably in all these areas and we continue to invest in our capabilities to ensure that we remain 
competitive in the future.

Customers

During the year ended December 31, 2018 revenue was earned from over 800 clients. During the year ended December 31, 2018
39.5% of our revenues were derived from our top five customers, with one customer contributing more than 10% of our revenues 
during the period (13.6%). No other customer contributed more than 10% of our revenues (including revenue from reimbursable 
expenses) during this period. During the year ended December 31, 2017 42.0% of our revenues were derived from our top five 
customers, with one customer contributing more than 10% of our revenues (including revenue from reimbursable expenses) during 
the period (21.0%).  No other customer contributed more than 10% of our revenues (including revenue from reimbursable expenses) 
during this period. See note 16 Disaggregation of Revenue.   

During the year ended December 31, 2016 45% of our net revenues (excluding reimbursable expenses) were derived from our top 
five customers, with one customer individually contributing more than 10% of our net revenues during the period (26%). No other 
customer contributed more than 10% of our net revenues during this period. 

The loss of, or a significant decrease in business from one or more of these key customers could have a material adverse impact 
on our results of operations.

Unsatisfied performance obligation

Our  unsatisfied  performance  obligation  consists  of  contracted  revenue  yet  to  be  earned  from  projects  awarded  by  clients. At 
December 31, 2018 we had contracted unsatisfied performance obligations of $5.3 billion (see note 17 Contract Balances). We 
believe that our backlog as of any date is not necessarily a meaningful predictor of future results due to the potential for cancellation 
or delay of the projects included in the backlog, and no assurances can be given on the extent to which we will be able to realize 
this backlog as net revenue.

Information Systems

Having  access  to  accurate  and  timely  information  is  critical  in  the  management,  delivery  and  quality  of  all  aspects  of  drug 
development. To enable this ICON has developed an Informatics strategy built around ICONIK, a web-based information platform 
that enables the management, reporting, analysis and visualization of all data relating to drug development. ICONIK collects, 
manages and standardizes study data from multiple sources, including Electronic Data Capture (EDC), patient diaries, central 
laboratories and imaging, to provide a single view of study information. ICONIK enables ICON to deliver new services such as 
ICONIK monitoring which uses near-real time clinical data to drive monitoring visit schedules thereby reducing overall cost and 
time to market.

In addition to managing clinical data, ICONIK collects operational data, such as project management, clinical trials management 
system (CTMS) and metric information to drive trial efficiency and transparency. Investigator data, such as payments, site details 
and  performance,  can  also  be  incorporated.  ICONIK  can  be  accessed  via  a  portal  that  allows  clients  access  to  study  related 
information via a secure web based environment. 

Firecrest, our site management and training technology, is another important component of our Informatics strategy. Firecrest 
provides an on-line web-based portal to access visit by visit study guides which drive site performance and quality. 

ICON also utilizes a range of enterprise applications that enable the delivery of our business services in a global environment. 
The focus is to provide ease of access and capture of study information for our staff and clients globally. Our current information 
systems are built on open standards and leading commercial business applications from vendors including Microsoft, Amazon, 
Oracle, Dell, SAS and Medidata. IT expenditure is authorized by strict IT governance policies requiring senior level approval of 
all strategic IT expenditure based on defined, measurable business benefits. 

In Clinical Operations, we have deployed a suite of software applications that assist in the management and tracking of our clinical 
trial activities. These software applications are both internally developed and commercially available applications from external 
vendors. These include a clinical trial management application that tracks all relevant data in a trial and automates all management 
and reporting processes. In our Data Management function, we have deployed leading clinical data management solutions including 
EDC and Clinical Data Warehouse solutions from external vendors. This allows us to guarantee the integrity of client data and 
provide  consolidated  information  across  client  studies.  In  our  clinical  trials  management  area  Firecrest  Clinical  provides  a 
comprehensive  site  performance  management  system  that  improves  compliance,  consistency  and  execution  of  activities  at 
investigative sites. The web-based solution enables accurate study information, including protocol information, training manuals 
and case report forms, to be rolled out quickly and simultaneously to sites. Site behaviour can then be tracked to ensure training 

27

is understood, procedures are being followed, timelines are met and study parameters are maintained. As well as meeting day to 
day operational requirements, these systems are feeder systems into the ICONIK platform.

We have also developed an interactive response technology (IXR) system which provides features such as centralized patient 
randomization, drug inventory management, patient diary collection and provides our clients with a fully flexible data retrieval 
solution which can be utilized via telephone, internet browser or a mobile device. In our central laboratory business, we utilize a 
comprehensive suite of software, including a laboratory information management system (LIMS), a kit / sample management 
system and a web interface system to allow clients to review results online. Our Laboratory also utilizes (IMRA) a web based 
laboratory application to facilitate detailed analysis of any potential trends, signal or alerts in Laboratory data. ICON provides 
imaging services through the use of it internally developed MIRA platform and also utilizes Medidata’s Rave Commercial Imaging 
for collecting, managing and processing data to support its imaging capabilities.  

ICON supports Population Pharmacokinetics & Pharmacokinetic Pharmacodynamic modeling though the use of its proprietary 
software NONMEM®. NONMEM® can also be accompanied with PDx-Pop proprietary software to provide graphical 
interfaces.

All of the Company’s global finance operations utilize Oracle’s eBusiness suite to serve the organization’s financial and project 
accounting requirements. Workday is used to fulfill our HR people management requirements.

The Company’s strategy of using technology to enhance our global processes can be seen from our deployment of platforms like 
ICONIK Metrics Stream EDMS/QMS our global SOP Document Management system, our Web-based training delivery solution, 
iLearn, workflow and automation platforms such as ServiceNow, Sailpoint for identity management and governance and Pega & 
Argus for pharmacovigilance. The Electronic Trial Master File is delivered via ICON’s proprietary software ICOMaster or the 
Wingspan software platform. Our business development and contracting teams use Salesforce.  

Our IT systems are operated from two Data Centre hubs in Dublin, Ireland and Philadelphia, Pennsylvania. These hubs reside 
within purpose built Data Centre facility locations. Other offices are linked to these hubs through a network managed by Verizon, 
a  tier  one  global  telecommunications  provider.  This  network  provides  global  connectivity  for  our  applications  and  allows 
collaboration and communication using tools like Cisco Jabber, WebEx, Sharepoint and Box. Mobile staff can also access all 
systems via secure remote access facilities. A global corporate intranet portal provides access to all authorized data and applications 
for our internal staff as well as providing an internal platform for company-wide communication. IT systems are protected with 
robust information security controls which are independently audited twice annually as part of maintaining ICON’s ISO27001:2013 
certification. 

Following the acquisition of Aptiv Solutions we have integrated and continue to enhance three new technology platforms into the 
ICON offerings. These comprise ADDPLAN for simulation and design of exploratory/pilot and confirmatory/ pivotal adaptive 
clinical trials (ADDPLAN® DF (Dose Finder), ADDPLAN® Base, ADDPLAN® MC (Multiple Comparison) and ADDPLAN® PE 
(Population Enrichment)); AptivAdvantage which is an integrated platform comprising EDC, randomization and drug supply 
management specifically created for execution of adaptive clinical trials and used to deliver risk-based monitoring; and Aptiv 
Insite which is a novel approach to risk-based monitoring, using Verification by Statistical Sampling (VSS) to manage data quality 
and site related risks. ICON utilizes PUBSHUB to automate medical and scientific communications and publications management.

Contractual Arrangements

We  are  generally  awarded  projects  based  upon  our  responses  to  requests  for  proposals  received  from  companies  in  the 
pharmaceutical, biotechnology and medical device industries, or work orders executed under our strategic partnership agreements.

Revenues on long term contracts are recognized based on an assessment of progress towards completion. Payment terms usually 
provide either for payments based on the delivery of certain identified milestones, units delivered or monthly payments, according 
to a contracted payment schedule over the life of the contract. Where clients request changes in the scope of a trial or in the services 
to be provided by us, a change order or amendment is issued which may result either in an increase or decrease in the contract 
value. We also contract on a "fee-for-service" or "time and materials" basis.

Contract periods may range from several weeks to several years depending on the nature of the work to be performed. In most 
cases, an upfront portion of the contract fee is paid at the time the study or trial is started. The balance of the contract fee is generally 
payable in installments over the study or trial duration and may be based on the completion of certain performance targets or 
"milestones", on units delivered, or on a fixed monthly payment schedule. For instance, installment payments may be based on 
patient enrollment dates or delivery of the database. 

28

On adoption of ASC 606 'Revenue from Contracts with Customers', we concluded that ICON is the contract principal in respect 
of both direct services and in the use of third parties (principally investigator services) that support the clinical trial. The progress 
towards completion for clinical service contracts is measured based on total project costs (direct fees are therefore inclusive of 
third party costs). Gross revenue or 'revenue' is therefore our primary measure of performance on adoption of ASC 606 and in 
presentation of our results for the year ended December 31, 2018. In common with others in the sector, our results previously 
separately  identified  that  revenue  stream  which  related  to  services  provided  by  third  parties. Those  services  were  previously 
separately identified as reimbursable expenses and presented separately in our Statement of Operations. Reimbursable expenses 
include payments to investigators, travel and accommodation costs and various other expenses incurred over the course of the 
clinical trial which are fully reimbursable by the client. Reimbursable expenses are included within direct costs on adoption of 
ASC 606. See note 26 for impact of new accounting policy. Reimbursable expenses are included within the contract and are 
invoiced on a monthly basis based on actual expenses incurred. Expenses incurred are determined by reference to activity. 

As the currency in which contracts are priced can be different from the currencies in which costs relating to those contracts are 
incurred, we usually negotiate currency fluctuation clauses in our contracts which allow for price adjustments if changes in the 
relative value of those currencies exceed predetermined tolerances.

Most of our contracts are terminable immediately by the client with justifiable cause or with 30 to 90 days’ notice without cause. 
In the event of termination, we are usually entitled to all sums owed for work performed and expenses incurred through the notice 
of termination and certain costs associated with termination of the study. Termination or delay in the performance of a contract 
occurs for various reasons, including, but not limited to, unexpected or undesired results, production problems resulting in shortages 
of the drug, adverse patient reactions to the drug, the client's decision to de-emphasize a particular trial, inadequate patient enrollment 
or investigator recruitment.

Government Regulation  

Regulation of Clinical Trials

The clinical investigation of new drugs is highly regulated by government agencies. The standard for the conduct of clinical 
research and development studies is Good Clinical Practice (“GCP”), which stipulates procedures designed to ensure the quality 
and integrity of data obtained from clinical testing and to protect the rights and safety of clinical subjects. 

The FDA and other prominent regulators have promulgated regulations and guidelines that pertain to applications to initiate trials 
of products, the approval and conduct of studies, report and record retention, informed consent, applications for the approval of 
drugs and post-marketing requirements. Pursuant to these regulations and guidelines, service providers that assume the obligations 
of a drug sponsor are required to comply with applicable regulations and are subject to regulatory action for failure to comply 
with such regulations and guidelines. In the United States and Europe, the trend has been in the direction of increased regulation 
and enforcement by the applicable regulatory authority. 

In providing services in the United States, we are obligated to comply with FDA requirements governing such activities. These 
include ensuring that the study is approved by an appropriate Independent Review Board (“IRB”) and Ethics Committee, obtaining 
patient informed consents, verifying qualifications of investigators, reporting patients’ adverse reactions to drugs and maintaining 
thorough and accurate records. We must maintain critical documents for each study for specified periods, and such documents 
may be reviewed by the study sponsor and the FDA.

The services we provide outside the United States are ultimately subject to similar regulation by the relevant regulatory authority. 
In addition, our activities in Europe are affected by the European Medicines Agency.

We must retain records for each study for specified periods for inspection by the client and by the applicable regulatory authority 
during audits. If we fail to comply adequately with applicable regulations and guidelines, it could result in a material adverse 
effect. In addition, our failure to comply with applicable regulations and guidelines, depending on the extent of the failure, could 
result in fines, debarment, termination or suspension of ongoing research, the disqualification of data or litigation by clients, any 
of which could also result in a material adverse effect.

Potential Liability and Insurance  

The nature of our business exposes us to potential liability including, but not limited to, potential liability for (i) breach of contract 
or negligence claims by our customers; (ii) non-compliance with regulatory or legal obligations including, but not limited to, anti-
bribery and anti-corruption laws; (iii) third party (such as patients) claims in respect of our performance of services.

29

 
In addition, although we do not believe we are legally responsible for acts of third party investigators (physicians running trials), 
we could be subject to claims arising as a result of the actions of these investigators.

We try to reduce this potential liability by:

• 

Seeking contractual indemnification from customers in relation to certain activities. However, the terms and scope of 
indemnification varies from customer to customer and project to project and the performance of these indemnities is not 
secured. As a result, we bear the risk that indemnification may not be relevant or sufficient or that the indemnifying party 
may not have the financial ability to fulfill its indemnification obligations. Furthermore this indemnification does not 
protect us against our own acts or omissions such as our negligence or where our performance does not reach the required 
contractual, industry or regulatory standard.

•  Maintaining worldwide professional liability insurance. While we believe our insurance coverage is adequate, there is 
no guarantee that we will continue to be able to maintain such insurance coverage on terms acceptable to us, if at all, or 
that the relevant policy will respond and provide cover when we want it to.

We could be materially adversely affected if ICON is required to pay damages or bear the costs of defending or settling any claim 
outside the scope of or in excess of a contractual indemnification provision, an indemnifying party does not fulfill its indemnification 
obligations, the claim is in excess of level of our insurance coverage or the relevant circumstances are not covered by our insurance 
policies.

The following discussion and analysis should be read in conjunction with our Consolidated Financial Statements, accompanying 
notes  and  other  financial  information,  appearing  in  Item  18.  The  Consolidated  Financial  Statements  have  been  prepared  in 
accordance with U.S. GAAP.

Overview

We are a CRO, providing outsourced development services on a global basis to the pharmaceutical, biotechnology and medical 
device industries. We specialize in the strategic development, management and analysis of programs that support all stages of the 
clinical development process - from compound selection to Phase I-IV clinical studies. Our vision is to be the Global CRO partner 
of choice in drug development by delivering best in class information, solutions and performance in clinical and outcomes research.

We believe that we are one of a select group of CROs with the expertise and capability to conduct clinical trials in most major 
therapeutic areas on a global basis and have the operational flexibility to provide development services on a stand-alone basis or 
as part of an integrated “full service” solution. At December 31, 2018, we employed approximately 13,670 employees, in 89
locations in 37 countries. During the year ended December 31, 2018 we derived approximately 34.5%, 55.7% and 9.8% of our 
revenue in the United States, Europe and Rest of World, respectively.

Revenue consists of fees earned under contracts with third-party clients. In most cases, a portion of the contract fee is paid at the 
time the study or trial is started, with the balance of the contract fee generally payable in installments over the study or trial duration, 
based on the delivery of certain performance targets or milestones. Revenue from long term contracts is recognized on a proportional 

34

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
performance method based on the relationship between time incurred and the total estimated duration of the trial or on a fee-for-
service basis according to the particular circumstances of the contract. As is customary in the CRO industry, we contract with third 
party investigators in connection with clinical trials. Investigator costs and certain other third party costs are included in our 
assessment of progress towards completion and costs incurred in measuring revenue. Where these costs are reimbursed by clients, 
they are included in the total contract value recognized over time based on our assessment of progress towards completion. 

As the nature of our business involves the management of projects, the majority of which have a duration of one to four years, 
the commencement or completion of projects in a fiscal year can have a material impact on revenues earned with the relevant 
clients in such years. In addition, as we typically work with some, but not all divisions of a client, fluctuations in the number and 
status of available projects within such divisions can also have a material impact on revenues earned from such clients from year 
to year.

Termination or delay in the performance of an individual contract may occur for various reasons, including, but not limited to, 
unexpected or undesired results, production problems resulting in shortages of the drug, adverse patient reactions to the drug, the 
client’s decision to de-emphasize a particular trial or inadequate patient enrollment or investigator recruitment. In the event of 
termination the Company is usually entitled to all sums owed for work performed through the notice of termination and certain 
costs associated with the termination of the study. In addition, contracts generally contain provisions for renegotiation in the event 
of changes in the scope, nature, duration, or volume of services of the contract.

Our unsatisfied performance obligation comprises our assessment of contracted revenue yet to be earned from projects awarded 
by clients. At December 31, 2018 we had a backlog of approximately $5.3 billion. We believe that our backlog as of any date is 
not necessarily a meaningful predictor of future results, due to the potential for cancellation or delay of the projects included in 
the backlog, and no assurances can be given on the extent to which we will be able to realize the backlog.

Although we are domiciled in Ireland, we report our results in U.S. dollars. As a consequence the results of our non-U.S. based 
operations, when translated into U.S. dollars, could be materially affected by fluctuations in exchange rates between the U.S. dollar 
and the currencies of those operations.

In addition to translation exposures, we are also subject to transaction exposures because the currency in which contracts are priced 
can be different from the currencies in which costs relating to those contracts are incurred. Our operations in the United States are 
not materially exposed to such currency differences as the majority of our revenues and costs are in U.S. dollars. However, outside 
the United States the multinational nature of our activities means that contracts are usually priced in a single currency, most often 
U.S. dollars or euro, while costs arise in a number of currencies, depending, among other things, on which of our offices provide 
staff for the contract and the location of investigator sites. Although many such contracts benefit from some degree of natural 
hedging, due to the matching of contract revenues and costs in the same currency, where costs are incurred in currencies other 
than those in which contracts are priced, fluctuations in the relative value of those currencies could have a material effect on our 
results of operations. We regularly review our currency exposures.

As we conduct operations on a global basis, our effective tax rate has depended and will depend on the geographic distribution of 
our revenue and earnings among locations with varying tax rates. Our results therefore may be affected by changes in the tax rates 
of the various jurisdictions. In particular, as the geographic mix of our results of operations among various tax jurisdictions changes, 
our effective tax rate may vary significantly from period to period.

The provisions of ASC 606 were applied in the preparation and presentation of the results for the twelve months ended December 
31, 2018. As ICON adopted the standard using the cumulative effect transition method, there is no restatement of comparative 
amounts. The results for the year ended December 31, 2017 and previously therefore reflect the provisions of ASC 605 'Revenue 
Recognition'. The most significant impact of application of the new standard reflects the measurement of a clinical trial service 
as a single performance obligation recognized over time. We have concluded that ICON is the contract principal in respect of both 
direct services and in the use of third parties (principally investigator services) that support the clinical trial. The progress towards 
completion for clinical service contracts is measured based on total project costs (direct fees are therefore inclusive of third party 
costs). Gross revenue is therefore our primary measure of performance on adoption of ASC 606. In common with others in the 
sector, our results previously separately identified that revenue stream which related to services provided by third parties. Those 
services were previously separately identified as reimbursable expenses and presented separately in our Statement of Operations. 
Reimbursable expenses are included within direct costs on adoption of ASC 606. See note 26 for impact of new accounting policy. 
Consistent with the provisions of ASC 606, our commentary and analysis in respect of the results for the year-ended December 
31, 2018 reflect our assessment of revenue as presented. Our commentary and analysis in respect of the results for the years ended 
December 31, 2017 and previously refer to net revenue unless otherwise stated (direct fee revenue excluding amounts reimbursable 
from third parties) as our primary measure of performance prior to the adoption of ASC 606.    

Year ended December 31, 2018 compared to year ended December 31, 2017

Revenue for the year increased by $193.5 million, or 8.1%, from $2,402.3 million (revenue including reimbursable expenses) for 
the year ended December 31, 2017 to $2,595.8 million for the year ended December 31, 2018. Revenue increased by 6.9% in 
constant currency or 3.7% in constant dollar organic. The increase in  revenues can be explained by both continued organic growth 
and the additional revenues from the acquisition of Mapi on July 27, 2017.

Revenues from our top five customers were $1,024.1 million in the year ended December 31, 2018 compared to $1,009.7 million 
in the year December 31, 2017 or 39.5% and 42% respectively. The largest of these customers related to a strategic partnership 
with a large global pharmaceutical company. Revenue (including revenue from reimbursables) from this customer contributed 
21% of revenue for the year ended December 31, 2017, compared to 14% of  revenue for the year ended December 31, 2018. The 
addition of new customer accounts, particularly large and mid-tier pharma customers and biotech customers have resulted in a 
reduction in this concentration of revenues from our top five customers.

Revenue in Ireland increased by $122.1 million in year ended December 31, 2018, from $944.1 million (gross revenue) for the 
year ended December 31, 2017 to $1,066.2 million for the year ended December 31, 2018. Revenue in Ireland during the year 
ended December 31, 2018 increased by 12.9% compared to an overall increase in group revenue of 8.1%.  Revenue in Ireland is 
principally a function of our global transfer pricing model. See note 19 Business Segment and Geographical Information for further 
details.

Revenue for Rest of Europe increased by $24.3 million or 6.8%, from $355.6 million for the year ended December 31, 2017 (gross  
revenue) to $379.9 million for the year ended December 31, 2018, principally reflecting the acquisition of Mapi in July 2017. 

Revenue in the U.S. increased by $13.1 million or 1.5%, from $881.8 million for the year ended December 31, 2017 (gross revenue) 
to $895.0 million for the year ended December 31, 2018. Revenues in the U.S. were positively impacted by both continued organic 
growth and by the full year impact of the acquisition of Mapi in July 2017.

Revenue in our Rest of World (‘Other’) region increased by $33.9 million or 15.4%, from $220.8 million for the year ended 
December 31,  2017  (gross  revenue)  to  $254.7  million  for  the  year  ended  December 31,  2018.  Revenues  in  non-U.S.  dollar 
operations in this region were impacted by foreign currency translation and the movement in local rates to the U.S. dollar over 
the comparative year.  

Direct costs for the year increased by $790.9 million, or 77.0%, from $1,027.3 million for the year ended December 31, 2017 to 
$1,818.2 million for the year ended December 31, 2018. Direct costs for the year ended December 31, 2018 include reimbursable 
expenses of $702.8 million. Other direct costs increased by $88.1 million from $1,027.3 million for the year ended December 31, 
2017  to  $1,115.4  million.  Other  direct  costs  primarily  consist  of  compensation,  associated  fringe  benefits  and  share  based 
compensation expense for project-related employees and other direct project driven costs. The increase in other direct costs during 
the period arose due to an increase in headcount and a corresponding increase in personnel related expenditure of $81.3 million
combined with an increase in other direct project related costs of $1.5 million, increases in laboratory costs of $4.3 million and 
an increase in travel related costs of $1.0 million.  

Selling, general and administrative expenses for the year increased by $2.1 million, or 0.6%, from $323.7 million for the year 
ended December 31, 2017 to $325.8 million for the year ended December 31, 2018. Selling, general and administrative expenses 
comprise  primarily  of  compensation,  related  fringe  benefits  and  share  based  compensation  expense  for  non-project-related 
employees, recruitment expenditure, professional service costs, advertising costs and all costs related to facilities and information 
systems. As a percentage of revenue, selling, general and administrative expenses decreased from 13.5% of  revenue for the year 
ended December 31, 2017 to 12.6% of  revenue for the year ended December 31, 2018. Personnel related costs increased by $2.7 
million in the year, facilities related costs increased by $4.3 million and general overhead costs net of foreign exchange costs 
decreased by $5.0 million. 

Share based compensation expense recognized during the years ended December 31, 2018 and December 31, 2017 was $31.6 
million and $30.6 million respectively.

Depreciation expense for the year increased by $7.1 million or 16.4%, from $43.4 million for the year ended December 31, 2017
to $50.6 million for the year ended December 31, 2018. The depreciation charge reflects investments in facilities, information 
systems  and  equipment  supporting  the  Company’s  continued  growth. As  a  percentage  of  revenue,  the  depreciation  expense 
increased  from  1.8%  for  the  year  ended  December 31,  2017  to  1.9%  of  revenues  for  the  year  ended    December 31,  2018.  
Amortization expense for the year decreased by $2.5 million or 14.1%, from $17.9 million for the year ended December 31, 2017
to $15.4 million for the year ended December 31, 2018. The amortization expense represents the amortization of intangible assets 
acquired on business combinations. The amortization expense for the year incorporates a full year's amortization of intangibles 
acquired in the Mapi acquisition on July 27, 2017. These increases were offset by the completion of amortization on other assets.  
As a percentage of revenue, the amortization expense decreased from 0.7% of revenue for the year ended December 31, 2017 to 
0.6% of revenues for the year ended December 31, 2018.

During  the  year  ended  December 31,  2018  the  Company  implemented  a  restructuring  plan  to  improve  operating  efficiencies 
resulting  in  recognition  of  a  restructuring  charge  of  $12.5  million.  The  restructuring  plan  includes  the  cost  of  resource 
rationalizations in certain areas of the business to improve utilization. During the year ended December 31, 2017 the Company 
implemented a restructuring plan to improve operating efficiencies resulting in recognition of a restructuring charge of $7.8 million. 
See note 14 to the Audited Consolidated Financial Statements.

As a result of the above, income from operations increased by $35.0 million, or 10.4%, from $338.3 million ($346.1 million, 
excluding restructuring  and other charges) for the year ended December 31, 2017 to $373.4 million ($385.8 million excluding 
restructuring charges) for the year ended December 31, 2018 . As a percentage of revenue, income from operations increased from 
14.1% of revenues for year ended December 31, 2017 to 14.4% of revenues for year ended December 31, 2018.

Income from operations in Ireland increased by 10.8% from $232.0 million for the year ended December 31, 2017, to $257.1 
million for year ended December 31, 2018. Income from operations in Ireland and other geographic regions are reflective of the 
Company’s global transfer pricing model. Continued strategic investment in personnel and infrastructure together with on-going 
enhancement of operating processes and the successful leverage of support costs in 2018 has continued to result in a decrease of 
37

 
the proportion of the Group’s revenue used to support other Group entities and a corresponding increase in income from operations 
in Ireland during 2018.

In the Rest of Europe region, income from operations increased by $9.8 million, from $26.5 million for the year ended December 31, 
2017 to $36.3 million for the year ended December 31, 2018. Excluding restructuring charges recorded income from operations 
in the Rest of Europe increased by $10.6 million, from $26.4 million for the year ended December 31, 2017 to $36.9 million for 
the year ended December 31, 2018. As a percentage of  revenues income from operations in the Rest of Europe region increased
from 7.5% for the year ended December 31, 2017 to 9.6% for the year ended December 31, 2018.

In the U.S. region, income from operations increased by $0.3 million or 0.5%, from $58.3 million for the year ended December 31, 
2017 to $58.6 million for the year ended December 31, 2018. Excluding restructuring charges recorded income from operations 
in the U.S. increased by $0.2 million, from $58.2 million for the year ended December 31, 2017 to $58.3 million for the year ended 
December 31, 2018. As a percentage of revenues income from operations in the U.S. region decreased from 6.6% for the year 
ended December 31, 2017 to 6.5% for the year ended December 31, 2018.

In other regions, income from operations decreased by $0.1 million, from $21.5 million for the year ended December 31, 2017 to 
$21.4 million for the year ended December 31, 2018. Excluding restructuring charges recorded income from operations in other 
regions decreased by $0.1 million, from $21.5 million for the year ended December 31, 2017 to $21.4 million for the year ended 
December 31, 2018. As a percentage of  revenues, income from operations in the other regions decreased from 9.7% for the year 
ended December 31, 2017 to 8.4% for the year ended December 31, 2018.

Interest  expense  increased  from  $12.6  million  for  the  year  ended  December 31,  2017  to  $13.5  million  for  the  year  ended 
December 31, 2018.  No amounts were drawn down during the year ended December 31, 2017 or the year ended December 31, 
2018. Interest income for the year ended December 31, 2018 increased from $2.3 million for the year ended  December 31, 2017
to $4.8 million for the year ended December 31, 2018. 

Provision for income taxes for the period decreased from $46.6 million for the year ended December 31, 2017 to $42.0 million
for  the  year  ended  December 31,  2018. The  Company’s  effective  tax  rate  for  the  year  ended  December 31,  2018  was 
11.5% compared with 14.2% (12.0% excluding the impact of restructuring charges and non-recurring items including US tax 
reform) for the year ended December 31, 2017. The Company’s effective tax rate is principally a function of the distribution of 
pre-tax profits in the territories in which it operates.

Year ended December 31, 2017 compared to year ended December 31, 2016

Net revenue for the year increased by $91.9 million, or 5.5%, from $1,666.5 million for the year ended December 31, 2016 to 
$1,758.4 million for the year ended December 31, 2017. Revenue increased by 4.8% in constant currency. The increase in net 
revenues can be explained by both continued organic growth and the additional net revenues from the acquisition of Mapi on July 
27, 2017 and the full year impact of the acquisition of  ICON Government & Public Health Solutions (''GPHS'') (formerly Clinical 
Research Management) acquired on September 15, 2016.

Net revenues from our top five customers were $709.1 million in 2017 compared to $744.2 million in 2016, or 40% and 45% 
respectively.  The largest of these customers related to a strategic partnership with a large global pharmaceutical company.  Net 
revenue from this customer contributed 26% of net revenue for the year ended December 31, 2016, compared to 18% of net 
revenue for the year ended December 31, 2017.  The addition of new customer accounts, particularly large and mid-tier pharma 
customers and biotech customers have resulted in a reduction in this concentration of revenues from our top five customers. 

Net revenue in Ireland increased by $13.7 million in 2017, from $410.6 million for the year ended December 31, 2016 to $424.3 
million for the year ended December 31, 2017.  Net revenue in Ireland during the year ended December 31, 2017 increased by 
3.3% compared to an overall increase in Group revenue of 5.5%.  Net revenue in Ireland is principally a function of our global 
transfer pricing model.

Net revenue for Rest of Europe increased by $23.9 million or 7.6%, from $313.2 million for the year ended December 31, 2016 
to $337.1 million for the year ended December 31, 2017, principally reflecting the acquisition of Mapi in July 2017. Net revenue 
in the U.S. increased by $27.7 million or 3.6%, from $763.8 million for the year ended December 31, 2016 to $791.5 million for 
the year ended December 31, 2017. Net revenues in the U.S. were positively impacted by both continued organic growth and by 
the acquisition of Mapi on July 27, 2017 and the full year impact of the acquisition of ICON Government & Public Health Solutions 
(''GPHS'') on September 15, 2016. Net revenue in our Rest of World (‘Other’) region increased by $26.6 million or 14.9%, from 
$178.9 million for the year ended December 31, 2016 to $205.5 million for the year ended December 31, 2017.  Net revenues in 

38

non-U.S. dollar operations in this region were impacted by foreign currency translation and the movement in local rates to the 
U.S. dollar over the comparative year. 

Direct costs for the year increased by $66.0 million, or 6.9%, from $961.3 million for the year ended December 31, 2016 to 
$1,027.3 million for the year ended December 31, 2017. Direct costs consist primarily of compensation, associated fringe benefits 
and share based compensation expense for project-related employees and other direct project driven costs. The increase in direct 
costs during the period arose due to an increase in headcount and a corresponding increase in personnel related expenditure of 
$56.6 million combined with an increase in other direct project related costs of $11.7 million. These were offset by decreases in 
laboratory costs of $0.7 million and travel related costs of $1.7 million. As a percentage of net revenue, direct costs increased from 
57.7% of revenue for the year ended December 31, 2016 to 58.4% of net revenue for the year ended December 31, 2017.

Selling, general and administrative expenses for the year decreased by $2.0 million, or 0.6%, from $325.7 million for the year 
ended December 31, 2016 to $323.7 million for the year ended December 31, 2017. Selling, general and administrative expenses 
comprise  primarily  of  compensation,  related  fringe  benefits  and  share  based  compensation  expense  for  non-project-related 
employees, recruitment expenditure, professional service costs, advertising costs and all costs related to facilities and information 
systems. As a percentage of net revenue, selling, general and administrative expenses decreased from 19.5% of net revenue for 
the year ended December 31, 2016 to 18.4% of net revenue for the year ended December 31, 2017. Personnel related costs increased 
by $0.7 million in the year, facilities related costs decreased by $0.5 million and general overhead costs net of foreign exchange 
costs decreased by $2.1 million. During the year ended December 31, 2017, a credit of $6.0 million was recorded being the 
reduction in the assessment of the fair value of contingent consideration liability relating to the acquisition of (''GPHS'') (see note 
4 of the Financial Statements at Item 19). Once-off professional costs of $3.5 million related to a proposed transaction were also 
recorded. 

Share based compensation expense recognized during the years ended December 31, 2017 and December 31, 2016 was $30.6 
million and $40.3 million respectively.

Depreciation expense for the year increased by $1.3 million, or 3.1%, from $42.1 million for the year ended December 31, 2016 
to $43.4 million for the year ended December 31, 2017. The depreciation charge reflects investments in facilities, information 
systems and equipment supporting the Company’s continued growth.  As a percentage of net revenue, the depreciation expense 
remained unchanged at 2.5% of net revenues for the year ended December 31, 2016 and the year ended December 31, 2017.  
Amortization expense for the year increased by $0.4 million, or 2.3%, from $17.5 million for the year ended December 31, 2016 
to $17.9 million for the year ended December 31, 2017. The amortization expense represents the amortization of intangible assets 
acquired on business combinations. The amortization expense for the year includes amortization of intangibles acquired in the 
Mapi acquisition on July 27, 2017 and the impact of a full year’s amortization for GPHS acquired on September 15, 2016. These 
increases were offset by the cessation of amortization on other assets.  As a percentage of net revenue, the amortization expense 
decreased from 1.1% of net revenue for the year ended December 31, 2016 to 1.0% of net revenues for the year ended December 
31, 2017.

During the year ended December 31, 2017 the Company implemented a restructuring plan to improve operating efficiencies 
resulting in recognition of a restructuring charge of $7.8 million during 2017. The restructuring plan includes the cost of resource 
rationalizations in certain areas of the business to improve utilization. During the year ended December 31, 2016 the Company 
implemented a restructuring plan to improve operating efficiencies resulting in recognition of a restructuring charge of $8.2 million 
during  2016. The  restructuring  plan  includes  the  cost  of  resource  rationalizations  in  certain  areas  of  the  business  to  improve 
utilization (resulting in a charge of $6.2 million), and office consolidation (resulting in the recognition of an onerous lease obligation 
of $2.0 million). See note 14 to the Audited Consolidated Financial Statements.

As a result of the above, income from operations increased by $26.6 million, or 8.5%, from $311.7 million for the year ended 
December 31, 2016 to $338.3 million for the year ended December 31, 2017 ($26.2 million, or 8.2% excluding restructuring 
charges). As a percentage of net revenue, income from operations increased from 18.7% (19.2% excluding restructuring charges) 
of net revenues for year ended December 31, 2016 to 19.2% (19.7% excluding restructuring charges) of net revenues for year 
ended December 31, 2017.

Income from operations in Ireland increased by 7.4% from $216.1 million ($218.3 million excluding the impact of restructuring 
and other charges) for the year ended December 31, 2016, to $232.0 million ($240.1 million excluding the impact of restructuring 
and other charges) for year ended December 31, 2017. Income from operations in Ireland and other geographic regions are impacted 
by the Company’s global transfer pricing model. Continued strategic investment in personnel and infrastructure together with on-
going enhancement of operating processes and the successful leverage of support costs in 2017 has continued to result in a decrease 
of the proportion of the Group’s net revenue used to support other Group entities and a corresponding increase in income from 
operations in Ireland during 2017.

39

In the Rest of Europe region, income from operations decreased by $7.7 million, from $34.2 million for the year ended December 
31, 2016 to $26.5 million for the year ended December 31, 2017.  Excluding restructuring charges recorded income from operations 
in the Rest of Europe decreased by $10.1 million, from $36.5 million for the year ended December 31, 2016 to $26.4 million for 
the year ended December 31, 2017. As a percentage of net revenues income from operations in the Rest of Europe region decreased 
from 10.9% (11.7% excluding restructuring charges) for the year ended December 31, 2016 to 7.9% (7.8% excluding restructuring 
charges) for the year ended December 31, 2017. Income from operations in Europe and in Ireland in the three month period and 
year ended December 31, 2016 reflected the impact of a one-off intergroup transaction. This transaction resulted in an increase 
in income from operations in Europe and a decrease in income from operations in Ireland in that period.

In the U.S. region, income from operations increased by $17.0 million or 41.2%, from $41.3 million for the year ended December 
31, 2016 to $58.3 million for the year ended December 31, 2017. Excluding restructuring charges recorded income from operations 
in the U.S. increased by $13.6 million, from $44.6 million for the year ended December 31, 2016 to $58.2 million for the year 
ended December 31, 2017. As a percentage of net revenues income from operations in the U.S. region increased from 5.4% (5.8% 
excluding restructuring charges) for the year ended December 31, 2016 to 7.4% (7.3% excluding restructuring charges) for the 
year ended December 31, 2017, principally reflecting a credit of $6.0 million recorded on revaluation of the contingent consideration 
related to the acquisition of GPHS, the income contribution since acquisition of GPHS, and the impact of refinements to the 
consideration earned by US subsidiaries under the Group’s global transfer pricing model.  These increases were offset in part by 
increased amortization charges.

In other regions, income from operations increased by $1.5 million, from $20.0 million for the year ended December 31, 2016 to 
$21.5 million for the year ended December 31, 2017. Excluding restructuring charges recorded income from operations in other 
regions increased by $1.1 million, from $20.4 million for the year ended December 31, 2016 to $21.5 million for the year ended 
December 31, 2017. As a percentage of net revenues, income from operations in the other regions decreased from 11.2% (11.4% 
excluding restructuring charges) for the year ended December 31, 2016 to 10.4% (10.4% excluding restructuring charges) for the 
year ended December 31, 2017.

Interest expense decreased from $13.0 million for the year ended December 31, 2016 to $12.6 million for the year ended December 
31, 2017.  This decrease primarily reflects the drawdown of $53.0 million under the five year committed multi-currency Revolving 
Credit Facility in the year ended December 31, 2016. This facility bears interest at LIBOR plus a margin. No amounts were drawn 
down during the year ended December 31, 2017. Interest income for the year ended December 31, 2017 increased from $1.5 
million for the year ended December 31, 2016 to $2.3 million for the year ended December 31, 2017.

Provision for income taxes for the period increased from $38.0 million ($39.0 million excluding the impact of restructuring charges) 
for the year ended December 31, 2016 to $46.6 million ($47.5 million excluding the impact of restructuring charges) for the year 
ended December 31, 2017. The Company’s effective tax rate for the year ended December 31, 2017 was 14.2% (12.0% excluding 
the impact of restructuring charges and non-recurring items including US tax reform) compared with 12.7% (12.7% excluding 
the impact of restructuring charges) for the year ended December 31, 2016. The Company’s effective tax rate is principally a 
function of the distribution of pre-tax profits in the territories in which it operates.

Liquidity and Capital Resources

The CRO industry is generally not capital intensive. The Group’s principal operating cash needs are payment of salaries, office 
rents, travel expenditures and payments to investigators. Investing activities primarily reflect capital expenditures for facilities 
and information systems enhancements, the purchase and sale of short term investments and acquisitions.

Our clinical research and development contracts are generally fixed price with some variable components and range in duration 
from a few weeks to several years. Revenue from contracts is generally recognized as income on the basis of the relationship 
between costs incurred and the total estimated contract costs. The cash flow from contracts typically consists of a small down 
payment at the time the contract is entered into, with the balance paid in installments over the contract duration, in some cases on 
the achievement of certain milestones. Therefore, cash receipts do not correspond to costs incurred and revenue recognized on 
contracts.

The Company’s cash and available for sale investments at December 31, 2018 amounted to $455.8 million compared with cash 
and available for sale investments of $360.4 million at December 31, 2017. The Company’s cash and short term investment balances 
at  December 31,  2018  comprised  cash  and  cash  equivalents  $395.9  million  and  short-term  investments  $59.9  million.  The 
Company’s cash and short term investment balances at December 31, 2017 comprised cash and cash equivalents $282.9 million
and short-term investments $77.6 million.

On March 12, 2018, the Company entered into a five year committed multi-currency Revolving Credit Facility for $150.0 million 
with Citibank, JP Morgan, Santander, HSBC Bank and Morgan Stanley International (“Revolving Credit Facility”). Each bank 
subject to the agreement has committed $30.0 million to the facility, with equal terms and conditions in place with all institutions.  
The facility is guaranteed by ICON plc. The facility replaces the $100.0 million facility which was entered into in June 2014 due 
to mature in June 2019. The facility bears interest at LIBOR plus a margin. No amounts were drawn at December 31, 2018, or at  
December 31, 2017, in respect of the Revolving Credit Facility. Amounts available to the Group under the facility at December 31, 
2018 were $150.0 million and at December 31, 2017 were $100.0 million.

On July 27, 2017, a subsidiary of the Company, ICON Clinical Research Limited, acquired Mapi Development SAS ('Mapi'). 
Mapi is a leading patient-centered health outcomes research and commercialization company. Cash outflows on acquisition were 
$144.1 million.

On September 15, 2016, a subsidiary of the Company, ICON US Holdings Inc. acquired ICON Government & Public Health 
Solutions (''GPHS'') (formerly Clinical Research Management (ClinicalRM)) which resulted in net cash outflows of $52.4 million 
(including certain payments made on behalf of GPHS totaling $9.2 million).

On December 15, 2015, ICON Investments Five Unlimited Company issued Senior Notes for aggregate gross proceeds of $350.0 
million in a private placement. The Senior Notes will mature on December 15, 2020. Interest payable is fixed at 3.64%, and is 
payable semi-annually on the Senior Notes on each June 15 and December 15, which commenced on June 15, 2016. The Senior 
Notes are guaranteed by ICON plc. In October 2015, the Company entered into an interest rate hedge in respect of the planned 
issuance of the Senior Notes in December 2015. The interest rate hedge matured in November 2015 when the interest rate on the 
Senior Notes was fixed. The interest rate hedge was effective in accordance with Financial Accounting Standards Board (“FASB”) 
ASC 815, “Derivatives and Hedging”. The cash proceeds, representing the realized gain on the interest rate hedge, were received 
on maturity in November 2015.

On July 27, 2015 the Company entered into a 364 day bridge facility for $350.0 million with two financial institutions. The facility 
bore interest at LIBOR plus a margin and included certain guarantees and indemnities in favor of the two financial institutions. 
The bridge facility was repaid in full in December 2015.

Net cash provided by operating activities was $268.6 million for the year ended December 31, 2018 compared with net cash 
provided by operating activities of $383.1 million for the year ended December 31, 2017. 

41

The dollar value of these balances and the related number of days’ revenue outstanding (i.e. revenue outstanding as a percentage 
of revenue for the period, multiplied by the number of days in the period) can vary over a study or trial duration. Contract fees 
are generally payable in installments based on the achievement of certain performance targets or “milestones” (e.g. target patient 
enrollment rates, clinical testing sites initiated or case report forms completed), such milestones being specific to the terms of each 
individual contract, while revenues on contracts are recognized as contractual obligations as performed. Billed and unbilled revenue 
also includes amounts recoverable from customers in respect of reimbursable costs. On adoption of ASC 606, we concluded that 
ICON is the contract principal in respect of both direct services and in the use of third parties (principally investigator services) 
that support a clinical trial. The progress towards completion for clinical service contracts is measured based on total project costs 
(including reimbursable costs). Reimbursable expenses are included within direct costs on adoption of ASC 606 and are recorded 
based on activity undertaken by the third party. Amounts owed to investigators and others in respect of reimbursable expenses at 
December 31, 2018 were $85.6 million (see note 7 Other liabilities). Contractual terms with our customers require ICON to receive 
and discharge payment to third parties prior to billing the customer for these items. Days’ revenue outstanding will vary therefore 
due to, amongst others, the scheduling of contractual milestones over a study or trial duration, the achievement of a particular 
milestone during the period, the timing of receipt of invoices from third parties for reimbursable costs and or the timing of cash 
receipts from customers. A decrease in the number of days’ revenue outstanding during a period will result in cash inflows to the 
Company while an increase in days revenue outstanding will lead to cash outflows. The number of days’ revenue outstanding at 
December 31, 2018 was 67 days compared to 49 days at December 31, 2017 . This reflects both extended credit terms provided 
to a number of key accounts and timing of cash collections. The increase in days' revenue outstanding and a reduction in days 
payment outstanding resulted in a reduction in cash provided by operations.  

Net cash used in investing activities was $37.3 million for the year ended December 31, 2018 compared to net cash used in investing 
activities of $177.8 million for the year ended December 31, 2017. Net cash used in the year ended December 31, 2018 arose 
principally on the investment in capital expenditure of $48.4 million, offset in part by the net income on the sale of short-term 
investments of $18.9 million. In December 2017, net cash used in investing activities of $177.8 million was driven by cash paid 
for acquisitions of $144.1 million (excluding cash acquired with subsidiary undertaking of $19.6 million - see note 4 Business 
Combinations for further details), capital expenditures of $44.7 million and the purchase of short-term investments of $41.7 million 
offset by the sale of short-term investments of $33.1 million.  

Capital expenditure of $48.4 million for the year ended December 31, 2018 comprised mainly of expenditure on global infrastructure 
and information technology systems to support the Company’s growth. During the year ended December 31, 2018 the Company 
incurred a net cash outflow of $18.8 million in respect of the purchase and sale of short-term investments. This compares to receipt 
of a net $8.6 million during the year ended December 31, 2017. 

Net cash outflow from financing activities amounted to $113.0 million for the year ended December 31, 2018 compared with net 
cash outflow from financing activities of $119.3 million for the year ended December 31, 2017. Cash outflows in respect of 
financing activities includes consideration paid by the Company for share buybacks pursuant to the Company’s share repurchase 
program totalling $129.0 million in the year-ended December 31, 2018 (see note 12 Share Capital for further information). 
As a result of these cash flows, cash and cash equivalents increased by $113.0 million for the year ended December 31, 2018
compared to an increase of $90.3 million for the year ended December 31, 2017.

We expect to spend approximately $55 million in the next twelve months on further investments in information technology, the 
expansion of existing facilities and the addition of new offices. We believe that we will be able to fund our additional foreseeable 
cash needs for the next twelve months from cash flow from operations, existing cash balances and funds available under negotiated 
facilities. In the future, we may consider acquiring businesses to enhance our service offerings and global presence. Any such 
acquisitions could require additional external financing and we may from time to time seek to obtain funds from public or private 
issues of equity or debt securities. There can be no assurance that such financing will be available on terms acceptable to us.

Critical Accounting Policies

The preparation of consolidated financial statements in accordance with generally accepted accounting principles in the United 
States requires management to make estimates and judgments that affect the reported amounts of assets and liabilities at the date 
of the financial statements and the reported amounts of revenues and expenses during the reported period.

We base our estimates and judgments on historical experience and on the other factors that we believe are reasonable under current 
circumstances. Actual results may differ from these estimates if these assumptions prove to be incorrect or if conditions develop 
other than as assumed for the purposes of such estimates. The following is a discussion of the accounting policies used by us, 
which we believe are critical in that they require estimates and judgments by management.

Revenue Recognition

Significant management judgments and estimates must be made and used in connection with the recognition of revenue in any 
accounting period. Material differences in the amount of revenue in any given period may result if these judgments or estimates 
prove to be incorrect or if management’s estimates change on the basis of development of the business or market conditions. To 
date there have been no material differences arising from these judgments and estimates.

We earn revenues by providing a number of different services to our clients. These services, which are integral elements of the 
clinical development process, include clinical trials management, contract staffing, consulting, and laboratory services. Contracts 
range in duration from a number of months to several years. The criteria for revenue recognition is based on five steps: (1) identify 
the contract(s) with a customer; (2) identify the performance obligation in the contract; (3) determine the transaction price; (4) 
allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity 
satisfies the performance obligation.

The Company adopted ASC 606 ‘Revenue from Contracts with Customers’, with a date of initial application of January 1, 2018. 
The revenue recognition accounting policy applied in preparation of the results for the twelve months ended December 31, 2018
therefore reflect application of ASC 606. ICON has elected to adopt the standard using the cumulative effect transition method. 
See note 26 for details of adoption.  

The most significant impact of application of the standard relates to our assessment of performance and percentage of completion 
in respect of our clinical trial service revenue. Prior to application of ASC 606, the revenue attributable to performance was 
determined based on both input and output methods of measurement. We have concluded that under the new standard, a clinical 
trial  service  is  a  single  performance  obligation  satisfied  over  time  i.e.  the  full  service  obligation  in  respect  of  a  clinical trial 
(including those services performed by investigators and other parties) is considered a single performance obligation. Promises 
offered to the customer are not distinct within the context of the contract. We have concluded that ICON is the contract principal 
in respect of both direct services and in the use of third parties (principally investigator services) that support the clinical research 
project. The transaction price is determined by reference to the contract or change order value (total service revenue and pass-
through/ reimbursable expenses) adjusted to reflect a realizable contract value. An assessment of the realizable contract value is 
judgmental in nature. The realizable value assessment is updated at each reporting period, having regard to (i) contract terms and 
(ii) customer experience.  

Revenue is recognized on a percentage completion basis as the single performance obligation is satisfied. The progress towards 
completion for clinical service contracts is measured therefore based on an input measure being total project costs (inclusive of 
third party costs) at each reporting period. Measurement of the progress towards completion involves judgment and estimation.  
Assessment of completion requires an evaluation of labor and related time cost incurred at the reporting date and third party costs 
incurred at the reporting date. The assessment of third party costs incurred (principally investigator costs) requires a review of 
activity performed and recorded by the third party services providers. The timing of payments to third parties in respect of cost 
incurred reflect invoicing by third parties. The timing difference between the activity performed and receipt of invoices from third 
parties may result in significant accrued amounts at reporting periods.  

43

 
The assessment of progress towards completion also requires an up to date evaluation of the forecast costs to complete in respect 
of these projects. Given the long-term nature of the clinical trials, and the complex nature of those trials, the forecast costs to 
complete (being internal direct costs and costs that will be incurred by third parties (principally investigators)) is judgmental.  
Forecast time (and related costs) is determined by reference to (i) contract terms and (ii) past experience. Forecast third party costs 
to complete are determined by project by project reference to (i) contract terms and (ii) past experience.   

Our contracting services revenue is recognized on a right to invoice basis. Our consulting services revenue is recognized based 
on an assessment of progress towards completion at each reporting period. Laboratory services revenue is recognized when, or 
as, obligations under the terms of a contract are satisfied, which occurs when control of the products or services are transferred 
to the customer. Service revenue is recognized over time as the services are delivered to the customer based on an assessment of 
progress towards completion.  

Impact of New Accounting Pronouncements 

Impact of new accounting pronouncements adopted during fiscal year-ended December 31, 2018

The Company adopted ASC 606 ‘Revenue from Contracts with Customers’, with a date of initial application of January 1, 2018. 
The revenue recognition accounting policy applied in preparation of the results for the twelve months ended December 31, 2018 
therefore reflect application of ASC 606. ICON has elected to adopt the standard using the cumulative effect transition method. 
See note 26 for details of adoption.

The new standard requires application of five steps: (1) identify the contract(s) with a customer; (2) identify the performance 
obligation in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in 
the contract; and (5) recognize revenue when (or as) the entity satisfies the performance obligation.

The most significant impact of application of the standard relates to our assessment of performance and percentage of completion 
in respect of our clinical trial service revenue. Prior to application of ASC 606, the revenue attributable to performance was 
determined based on both input and output methods of measurement. We have concluded that under the new standard, a clinical 
trial  service  is  a  single  performance  obligation  satisfied  over  time  i.e.  the  full  service  obligation  in  respect  of  a  clinical trial 
(including those services performed by investigators and other parties) is considered a single performance obligation. Promises 
offered to the customer are not distinct within the context of the contract. We have concluded that ICON is the contract principal 
in respect of both direct services and in the use of third parties (principally investigator services) that support the clinical research 
project. 

Impact of new accounting pronouncements which will be adopted during fiscal year-ended December 31, 2019 

In February 2016, the FASB issued ASU 2016-02, 'Leases', requiring lessees to recognize a right-of-use asset and a lease liability 
on the Consolidated Balance Sheet for all leases with the exception of short-term leases. For lessees, leases will continue to be 
classified as either operating or finance leases in the income statement. Lessor accounting is similar to the current model but 
updated to align with certain changes to the lessee model. Lessors will continue to classify leases as operating, direct financing 
or sales-type leases. The effective date of the new standard for public companies is for fiscal years beginning after December 15, 
2018 and interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted using a modified 
retrospective transition and requires application of the new guidance at the beginning of the earliest comparative period presented. 
The updated standard is effective for us beginning in the first quarter of the year-ended December 31, 2019. We are currently 
evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures. See note 
15 Commitments and Contingencies for details of operating leases held during year-ended December 31, 2018. A lease liability 
and right-of-use asset will be recorded on the Consolidated Balance Sheet at December 31, 2019. We estimate the impact of the 
adoption of ASC 842 will be the recognition of a right-of use asset and of lease liabilities in the range of $100 million to $110 
million. Under the new standard we expect an insignificant change in net result due to the replacement of operating lease expenses 
with amortization of the lease asset and the interest expense.   

In July 2018, the FASB issued ASU 2018-11, which creates a new, optional transition method for implementing ASU 2016-02 
and a lessor practical expedient for separating lease and non-lease components.
This ASU is effective:
For entities that have not early adopted ASU 2016-02 with the effective date of ASU 2016-02.
• 
• 
For entities that have early adopted ASU 2016-02 upon issuance. However, it can only be adopted by entities either at 
(1) the beginning of the company’s first reporting period after issuance or (2) the entity’s mandatory ASC 842 effective date. The 
Company has elected to adopt this transition method for implementing ASU 2016-02 and the related practical expedient.  

44

In July 2018, the FASB issued ASU 2018-10 which clarifies and corrects errors in ASC 842. The effective date and transition 
requirements in ASU 2018-10 are the same as the effective date and transition requirements of ASU 2016-02.

In January 2018, the FASB issued ASU 2018-01, which clarifies that land easements are in the scope of ASU 2016-02, 'Leases', 
and provides transition relief. The effective date and transition requirements in ASU 2018-01 are the same as the effective date 
and transition requirements of ASU 2016-02. This clarification does impact on the impact assessment of the adoption of ASC 842.

In August 2017, the FASB issue ASU 2017-12 'Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for 
Hedging Activities' which changes the recognition and presentation requirements of hedge accounting, including:

•  Eliminating the requirement to separately measure and report hedge ineffectiveness; and
• 

Presenting all items that affect earnings in the same income statement line item as the hedged item.

The ASU also provides new alternatives for:

•  Applying hedge accounting to additional hedging strategies;
•  Measuring the hedged item in fair value hedges of interest rate risk;
•  Reducing the cost and complexity of applying hedge accounting by easing the requirements for effectiveness testing, 

hedge documentation and application of the critical terms match method; and

•  Reducing the risk of material error correction if a company applies the shortcut method inappropriately.

This ASU is effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 
2018. Early adoption is permitted any time after the issuance of the ASU, including in an interim period. If adopted at other than 
the beginning of a fiscal year, cumulative effect adjustments are reflected as of the beginning of the fiscal year. The adoption of 
the ASU is not expected to have a significant impact on the financial statements.  

In February 2017, the FASB issued ASU 2017-05 'Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets 
(Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets'.  
In February 2017, the FASB issued ASU 2017-05 which clarifies the guidance in Subtopic 610-20 on accounting for derecognition 
of a nonfinancial asset. The ASU also defines in-substance nonfinancial assets and includes guidance on partial sales of non-
financial assets. The adoption of ASU 2017-05 is not expected to have an impact on the financial statements. 

In July 2017, the FASB issued ASU 2017-11 'Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); 
Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part 
II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and 
Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception' under which down round features will not 
cause certain equity-linked financial instruments to be accounted for as derivatives. A company that presents EPS information 
will reflect the effect of a down round feature of free-standing equity-linked financial instruments in EPS only if it is triggered. 
The ASU is effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2018.   
The adoption of the ASU is not expected to have an impact on the financial statements.

In June 2016, the FASB issued ASU 2016-13 'Measurement of Credit Losses on Financial Instruments', which significantly changes 
the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses 
expected to occur over their remaining life. The ASU is effective for public business entities that are SEC filers for interim and 
annual periods in fiscal years beginning after December 15, 2019. The adoption of ASU 2016-13 is not expected to have a significant 
impact on the financial statements.

In  July  2018,  the  FASB  issued ASU  2018-09,  which  clarifies  and  corrects  unintended  application  of  guidance,  and  makes 
improvements to several Codification Topics.  The changes are part of an ongoing FASB project to make non-substantive technical 
corrections, clarifications, and improvements that are not expected to have a significant effect on accounting practice or create a 
significant administrative cost to most entities. Most of the amendments are effective immediately. 
Some of the amendments are effective for:
Public business entities for annual and interim periods in fiscal years beginning after December 15, 2018.
• 
• 
All other entities for annual periods in fiscal years beginning after December 15, 2019 and interim periods in fiscal years 
beginning after December 15, 2020.   Other amendments, which affect recently issued ASUs that are not yet effective, are effective 
with the original ASU. The impact of adoption of ASU 2018-09 is not expected to be significant.  

In June 2018, the FASB issued ASU 2018-08 which clarifies and improves current guidance about whether a transfer of assets (or 
the reduction, settlement, or cancellation of liabilities) is a contribution or an exchange transaction. For transactions in which an 
entity is either a public business entity or an NFP that has issued, or is a conduit bond obligor for securities that are traded, listed, 
or quoted on an exchange or an over-the-counter market and serves as a resource recipient, the entity should apply the amendments 
45

in this ASU on contributions received to annual and interim periods in fiscal years beginning after June 15, 2018. All other entities 
should apply the amendments for transactions in which the entity serves as the resource recipient to annual periods in fiscal years 
beginning after December 15, 2018, and interim periods in fiscal years beginning after December 15, 2019. For transactions in 
which an entity is either a public business entity or an NFP that has issued, or is a conduit bond obligor for securities that are 
traded, listed, or quoted on an exchange or an over-the-counter market and serves as a resource provider, the entity should apply 
the amendments in this ASU on contributions made to annual and interim periods in fiscal years beginning after December 15, 
2018. All other entities should apply the amendments for transactions in which the entity serves as the resource provider for annual 
periods in fiscal years beginning after December 15, 2019 and interim periods in fiscal years beginning after December 15, 2020.  
Early adoption of the amendments is permitted. The adoption of ASU 2018-08 is not expected to have a significant impact on the 
financial statements. 

In February 2018, the FASB issued ASU 2018-02 which allows a reclassification from accumulated other comprehensive income 
to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. This ASU is effective for all entities for 
annual and interim periods in fiscal years beginning after December 15, 2018. Early adoption is permitted, including adoption in 
any interim period, (1) for public business entities for reporting periods for which financial statements have not yet been issued 
and (2) for all other entities for reporting periods for which financial statements have not yet been made available for issuance.   
The adoption of ASU 2018-02 is not expected to have a significant impact on the financial statements. 

In December 2017, the FASB issued ASU 2017-15. The ASU eliminates Topic 995, which includes an exemption to the recognition 
of deferred taxes on certain statutory reserve deposits that were, but are no longer, tax deferred. This ASU is effective for all entities 
for annual and interim periods in fiscal years beginning after December 15, 2018. Early adoption is permitted for all entities, 
including adoption in an interim period. The adoption of ASU 2017-15 is not expected to have a significant impact on the financial 
statements. 

Impact of other new accounting pronouncements 

In January 2017, the FASB issued ASU 2017-04 'Intangibles - Goodwill and Other: Simplifying the test for goodwill impairment' 
which requires an entity to no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, 
impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. The ASU 
is effective for public businesses, that are SEC filers, for annual and interim periods in fiscal years beginning after December 15, 
2019. The adoption of ASU 2017-04 is not expected to have a significant impact on the financial statements.  

In August 2018, the FASB issued ASU 2018-15, which clarifies that implementation costs incurred by customers in cloud computing 
arrangements are deferred if they would be capitalized by customers in software licensing arrangements under the internal-use 
software guidance.
This ASU is effective for:
• 
• 

Public business entities for annual and interim periods in fiscal years beginning after December 15, 2019.
Early adoption is permitted. Our evaluation of the impact of adoption of ASU 2018-15 is on-going.

In August 2018, the FASB issued ASU 2018-13 which aims to improve the overall usefulness of disclosures to financial statement 
users and reduce unnecessary costs to companies when preparing fair value measurement disclosures. This ASU is effective for 
all entities for annual and interim periods in fiscal years beginning after December 15, 2019. Retrospective adoption is required 
except for the following changes, which are required to be applied prospectively for only the most recent interim or annual period 
presented in the initial fiscal year of adoption:
• 
• 
and
• 
Early adoption is permitted. An entity may early adopt any eliminated or modified disclosure requirements and delay adoption of 
the additional disclosure requirements until their effective date. In such cases, users should refer to the Codification for disclosure 
requirements. Our evaluation of the disclosure impact of adoption of ASU 2018-13 is on-going.

Changes in unrealized gains and losses included in other comprehensive income for Level 3 instruments;
The range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements; 

The narrative description of measurement uncertainty.

46

In August 2018, the FASB issued ASU 2018-12 which changes how insurance entities recognize, measure, present and disclose 
long-duration contracts. This ASU is effective for:
• 
• 

Public business entities for annual and interim periods in fiscal years beginning after December 15, 2020.
Early adoption is permitted. The adoption of ASU 2018-12 is not expected to impact on the financial statements.

In June 2018, the FASB issued ASU 2018-07 which more closely aligns the accounting for employee and nonemployee share-
based payments.
This ASU is effective for:
• 
• 

Public business entities for annual and interim periods in fiscal years beginning after December 15, 2018. 
The adoption of ASU 2018-07 is not expected to have a significant impact on the financial statements. 

Inflation

We believe that the effects of inflation generally do not have a material adverse impact on our operations or financial conditions.

Board Practices

Board of Directors

The business of the Company is managed by the Directors who may exercise all the powers of the Company which are not required 
by the Companies Act 2014 of Ireland or by the Constitution of the Company to be exercised by the Company in general meeting.  
A meeting of Directors at which a quorum is present may exercise all powers exercisable by the Directors. The Directors may 
delegate (with power to sub-delegate) to any Director holding any executive office and to any Committee consisting of one or 
more Directors, together with such other persons as may be appointed to such Committee by the Directors, provided that a majority 
of the members of each Committee appointed by the Directors shall at all times consist of Directors and that no resolution of any 
such Committee shall be effective unless two of the members of the Committee present at the meeting at which it was passed are 
Directors.

The Board comprises one executive and ten outside Directors at the date of this report. The outside Directors bring independent 
judgment to bear on issues of strategy, performance, resources, key appointments and standards. The Company considers all of 
its  outside  Directors  to  be  of  complementary  skills,  experience  and  knowledge  and  each  outside  Director  has  specific  skills, 
experience  and  knowledge  that  are  valuable  to  the  Company. The  Board  members  between  them  have  very  strong  financial, 
pharmaceutical, CRO, scientific, medical and other skills and knowledge which are harnessed to address the challenges facing 
the Group. The Board meets regularly throughout the year and all Directors have full and timely access to the information necessary 
for them to discharge their duties. The Directors have access to the advice and services of the Company Secretary and may seek 
external independent professional advice where required. The Board considers its current size (11 Directors) to be adequate but 
continues to look for suitable qualified potential candidates to join the Board.

As set out below, certain other matters are delegated to Board Committees and all Board Committees report to the Board. The 
Company maintains what it considers an appropriate level of insurance cover in respect of legal action against its Directors. The 
Board, through the Nominating and Governance Committee, engages in succession planning for the Board and in so doing considers 
the strength and depth of the Board and the levels of knowledge, skills and experience of the Directors necessary for the Company 
to achieve its objectives. The Board meets at least four times each year. During the year ended December 31, 2018 the Board held 
seven board meetings. All Directors allocated sufficient time to the Company during the year ended December 31, 2018 to effectively 
discharge their responsibilities to the Company.

Directors’ retirement and re-election

The Company’s Constitution provides that, unless otherwise determined by the Company at a general meeting, the number of 
Directors shall not be more than 15 nor less than 3. At each annual general meeting, one third of the Directors who are subject to 
retirement by rotation, rounded down to the next whole number if it is a fractional number, shall retire from office. The Directors 
to retire shall be those who have been longest in office, but as between persons who became or were last re-appointed on the same 
day, those to retire shall be determined, unless otherwise agreed, by lot. Any additional Director appointed by the Company shall 
hold office until the next annual general meeting and will be subject to re-election at that meeting. Accordingly, at the annual 
general meeting of the Company to be held in 2019, it is anticipated that three Directors will retire in accordance with the Constitution 
and offer themselves for re-election. The Board of Directors adopted a Non-Executive Director Policy for Service on April 24, 
2018 which provides that, subject to individual waiver by the Board, an outside director of ICON plc shall serve on the Board of 
the Directors for an initial term which expires at the fourth annual general meeting after their appointment. Each outside Director 
may serve for a further two terms of 3 years each subject to the Board’s approval.  After the final 3 year term the Board may request 
that the outside Director serve for a further 1 year term which may be renewed annually subject to the Board’s approval. For an 
outside director who previously served as an executive of the Company, the initial 3 year term referred to in this policy is deemed 
50

to commence on the date that he is determined to be independent as per the NASDAQ Rules. This policy does not apply to Dr. 
John Climax as he is a founder of the Company.  

Lead Independent Director 

The Board of Directors adopted a Lead Independent Director Charter on February 14, 2017 which provides that in circumstances 
where the Chairman of the Board is not independent, the independent members of the Board of Directors shall appoint, from 
among  their  number,  a  Lead  Independent  Director.  The  Lead  Independent  Director  shall  generally  assist  in  optimizing  the 
effectiveness and independence of the Board of Directors by performing such duties as described in the charter, on behalf of the 
Board of Directors, including coordinating the meetings of the other non-employee and independent directors, and such other 
duties as determined from time to time by the Board of Directors and/or its independent members. Mr. Declan McKeon, who 
served as Lead Independent Director since March 1, 2017 stepped down on January 1, 2019 and Mr. Ronan Murphy was appointed 
as Lead Independent Director with effect from that date. 

Board committees

The Board has delegated some of its responsibilities to Board Committees. There are four permanent Committees. These are the 
Audit Committee, the Compensation and Organization Committee, the Nominating and Governance Committee and the Execution 
Committee. Each Committee has been charged with specific responsibilities and each has written terms of reference that are 
reviewed periodically. Minutes of Committee meetings are available to all members of the Board. The Company Secretary is 
available to act as secretary to each of the Board Committees if required. Appropriate key executives are regularly invited to attend 
meetings  of  the  Board  committees. The Audit  Committee,  Compensation  and  Organization  Committee  and  Nominating  and 
Governance Committee each completed a self-evaluation of the performance of the committee in respect to the year ended December 
31, 2018 and each committee was satisfied with their performance.

Audit Committee

The Audit  Committee  meets  a  minimum  of  four  times  a  year.  It  reviews  the  quarterly  and  annual  financial  statements,  the 
effectiveness of the system of internal control and recommends the appointment and removal of the external auditors. It monitors 
the adequacy of internal accounting practices and addresses all issues raised and recommendations made by the external auditors.  
The Audit Committee pre-approves all audit and non-audit services provided to the Company by its external auditors on a quarterly 
basis. The Audit Committee, on a case by case basis, may approve additional services not covered by the quarterly pre-approval, 
as the need for such services arises. The Audit Committee reviews all services which are provided by the external auditor to review 
the  independence  and  objectivity  of  the  external  auditor,  taking  into  consideration  relevant  professional  and  regulatory 
requirements. The Chief Financial Officer, the Head of Internal Audit, the General Counsel and the external auditors normally 
attend all meetings of the Audit Committee and have direct access to the Committee Chairman at all times. The Audit Committee 
is currently comprised of four independent Directors: Ronan Murphy (Chairperson), Declan McKeon, Professor Hugh Brady and 
Eugene McCague. Professor Dermot Kelleher and Professor William Hall, who served as a members of the Committee during 
2018, stepped down  on May 1, 2018. Professor Hugh Brady and Eugene McCague joined the Committee on May 1, 2018. Declan 
McKeon stepped down as Chairperson and Ronan Murphy assumed the position of Chairperson of the Committee with effect 
from February 19, 2019. 

Compensation and Organization Committee

The Compensation and Organization Committee is responsible for senior executive remuneration. The committee aims to ensure 
that remuneration packages are competitive so that individuals are appropriately rewarded relative to their responsibility, experience 
and value to the Company. Annual bonuses for the executive Directors and senior executive management are determined by the 
committee based on the achievement of the Company’s objectives. The Committee also oversees succession planning for the 
Company’s  senior  management.  The  Compensation  and  Organization  Committee  is  currently  comprised  of  the  following 
independent Directors: Joan Garahy (Chairperson), Professor William Hall,  Mary Pendergast and Ronan Murphy. Declan McKeon, 
who served as a member of the Committee during 2018, stepped down as a member of the Committee on May 1, 2018. Joan 
Garahy joined the Committee on May 1, 2018. Ronan Murphy stepped down as Chairperson of the Committee and Joan Garahy 
assumed the position Chairperson with effect from February 19, 2019. 

Nominating and Governance Committee

The Nominating and Governance Committee reviews the membership of the Board of the Company and Board committees on an 
ongoing basis. As part of this it regularly evaluates the balance of skills, knowledge and experience on the Board and then, based 
on this evaluation, identifies and, if appropriate, recommends individuals to join the Board of the Company. The Committee uses 
51

an external search consultant as needed to assist it in identifying potential new outside Directors. Once potential suitable candidates 
are identified either by the external search consultants or by members of the Nominating and Governance Committee, the Committee 
then discusses and considers the skills, knowledge and experience of the potential candidate. The Committee will assess if the 
Board of the Company requires and would benefit from the potential candidate’s skills, knowledge and experience and, if it decides 
the potential candidate is suitable, the Committee would recommend to the Board of the Company that the potential candidate be 
appointed. The Board of the Company then decides whether or not to appoint the candidate. The Committee considers diversity 
of the Board members when making recommendations to the Board of the Company. The Nominating and Governance Committee 
currently comprises the following independent Directors: Professor William Hall (Chairperson), Declan McKeon and Joan Garahy. 
Ronan Murphy, who served as a member of the Committee during 2018, stepped down as a member of the Committee on May 1, 
2018. Joan Garahy joined the Committee on May 1, 2018. 

Execution Committee

The primary function of the Execution Committee is to exercise the powers and authority of the Board in intervals between meetings 
of the Board within the limits set out in the Charter of the Execution Committee. The Execution Committee exercises business 
judgment to act in what the committee members reasonably believe to be in the best interest of the Company and its shareholders. 
All powers exercised by the Execution Committee are ratified at board meetings. This Committee convenes as often as it determines 
to be necessary or appropriate. The Execution Committee is currently comprised of the following Directors and Officer: Steve 
Cutler (Chairperson), Ronan Murphy, and Brendan Brennan. On January 1, 2019, Declan McKeon stepped down as a member of

Executive Officers and Directors Remuneration

Compensation Discussion & Analysis

Remuneration policy

The Compensation and Organization Committee seeks to achieve the following goals with the Company’s executive compensation 
programs: to attract, motivate and retain key executives and to reward executives for value creation. The Committee seeks to foster 
a performance-oriented environment by ensuring that a significant portion of each executive’s cash and equity compensation is 
based on the achievement of performance targets that are important to the Company and its shareholders.

The Company’s executive compensation program has three main elements: base salary, a bonus plan and equity incentives in the 
form of share related awards granted under the Company’s equity incentive plans. All elements of key executives’ compensation 
are  determined  by  the  Compensation  and  Organization  Committee  based  on  the  achievement  of  the  Group’s  and  individual 
performance objectives. Base salary, bonus awards and Directors’ fees were determined by the Compensation and Organization 
Committee in U.S. dollars or euro. 

Outside Directors’ remuneration

Outside Directors are remunerated by way of Directors’ fees and are also eligible for participation in the share option scheme. 
During 2018, each Outside Director (excluding the Board Chairman) was paid an annual retainer of $65,000 and additional fees 
for Board Committee service.

Mr. Murray’s Executive Chairman term expired on May 12, 2018 and he transitioned to the Outside Director role of Non-Executive 
Chairman. The arrangements with the Non-Executive Chairman of the Board provide for payment of €300,000 (translated at 
average rate for the year: $355,380) annually.  During 2018, Mr. Declan McKeon served as Lead Independent Director and received 
an additional fee of $25,000 for this role. Mr. Ronan Murphy was appointed as Lead Independent Director with effect from 1 
January 2019 and he will receive an additional fee of $25,000 for this role.

Outside Directors are not eligible for performance related bonuses and no pension contributions are made on their behalf. The 
Compensation and Organization Committee sets non-Executive remuneration.

Executive Directors’ and Key Executive Officers’ remuneration

Total cash compensation is divided into a base salary portion and a bonus incentive portion. The Committee targets total cash 
compensation with regard to healthcare/ biopharmaceutical companies of similar market capitalization and peer CRO companies, 
adjusted upward or downward based on individual performance and experience and level of responsibility. The Compensation 
and Organization Committee believes that the higher the executive’s level of responsibility within the Company, the greater the 
percentage of the executive’s compensation that should be tied to the Company’s performance. Target bonus incentive for executive 
officers range between 50% and 100% with actual pay outs ranging from 25% to 100% of salary based on group and individual 
performance.

A total bonus of $1.4 million was awarded to the following individuals; Dr. Steve Cutler Chief Executive Officer ($1.1 million) 
and Mr. Brendan Brennan Chief Financial Officer ($0.3 million) to reflect their contribution to the performance of the Company 
during 2018. These amounts were approved by the Compensation and Organization Committee and will be paid during the year-
ended December 31, 2019.

The Company’s executives are eligible to receive equity incentives, including stock options, restricted share units and performance 
share units, granted under the Company’s equity incentive plans. If executives receive equity incentive grants, they are normally 
approved annually at the first scheduled meeting of the Committee in the fiscal year. The grant date is determined by the Committee, 
and grants are awarded at the closing price on the day of grant. Newly hired executives may receive sign-on grants. In addition, 
the Committee may, at its discretion, issue additional equity incentive awards to executives if the Committee determines such 
awards are necessary to ensure appropriate incentives are in place. The number of equity awards granted to each participant is 
determined primarily by the Committee at the start of each year based on peer groups and advice from independent compensation 
consultants.

All executive officers are eligible to participate in applicable pension plans. The Company’s contributions are generally a fixed 
percentage of their annual compensation, supplementing contributions by the executive. The Company has the discretion to make 
additional contributions if deemed appropriate by the Committee. The Company’s contributions are determined at the peer group 
53

median of comparable Irish companies and peer CRO companies. Contributions to this plan are recorded as an expense in the 
Consolidated Statement of Operations.

Third party Agreements and Arrangements

ICON has not identified any arrangements or agreements relating to compensation or other payments provided by a third party to 
ICON’s directors or director nominees in connection with their candidacy or board service as required to be disclosed pursuant 
to NASDAQ Rule 5250(b)(3).

In February 2018, the Board approved the appointment of Mr. Murray as non-Executive Chairman of the Board of Directors with 
effect from May 12, 2018. Mr. Murray ceased to be an employee of the Company as of this date. Mr. Murray was granted and 
held ordinary share options, Restricted Share units and Performance Share units as Chief Financial Officer, Chief Executive Officer 
and Executive Chairman. The vesting of the Ordinary Share Options and Restricted Share Units which were unvested on Mr. 
Murray ceasing to be an ICON plc employee (May 12, 2018) were accelerated and the outstanding Ordinary Share Options and 
Restricted Share Units vested on that date. The unvested Performance Share Units with vesting dates between May 12, 2018 and 
March 2019 were forfeit on Mr. Murray ceasing to be an ICON plc employee on May 12, 2018.     

Equity Incentive Plans

On April 23, 2013 the Company adopted the 2013 Employees Restricted Share Unit and Performance Share Unit Plan (the “2013 
RSU Plan”) pursuant to which the Compensation and Organization Committee of the Company’s Board of Directors may select 
any employee, or any Director holding a salaried office or employment with the Company, or a Subsidiary to receive an award 
under the plan. On May 11, 2015, the 2013 RSU Plan was amended and restated in order to increase the number of ordinary shares 
that can be issued under the RSU Plan by 2.5 million shares. Accordingly, an aggregate of 4.1 million ordinary shares have been 
reserved for issuance under the 2013 RSU Plan. The shares are awarded at par value and vest over a service period. Awards under 
the 2013 RSU Plan may be settled in cash or shares at the option of the Company.

On July 21, 2008 the Company adopted the 2008 Employees Restricted Share Unit Plan (the “2008 RSU Plan”) pursuant to which 
the Compensation and Organization Committee of the Company’s Board of Directors may select any employee, or any Director 
holding a salaried office or employment with the Company or a Subsidiary to receive an award under the plan. An aggregate of 
1.0 million ordinary shares have been reserved for issuance under the 2008 RSU Plan.

On July 21, 2008 the Company adopted the Employee Share Option Plan 2008 (the “2008 Employee Plan”) pursuant to which 
the Compensation and Organization Committee of the Company’s Board of Directors may grant options to any employee, or any 
Director holding a salaried office or employment with the Company or a Subsidiary for the purchase of ordinary shares. On the 
same date, the Company also adopted the Consultants Share Option Plan 2008 (the “2008 Consultants Plan”), pursuant to which 
the Compensation and Organization Committee of the Company’s Board of Directors may grant options to any consultant, adviser 
or non-executive Director retained by the Company or any Subsidiary for the purchase of ordinary shares.

On February 14, 2017 both the 2008 Employee Plan and the 2008 Consultants Plan (together the “2008 Option Plans”) were 
amended and restated in order to increase the number of options that can be issued under the 2008 Consultants Plan from 400,000 
to 1 million and to extend the date for options to be granted under the 2008 Option Plans. An aggregate of 6.0 million ordinary 
shares have been reserved under the 2008 Employee Plan as reduced by any shares issued or to be issued pursuant to options 
granted under the 2008 Consultants Plan under which a limit of 1 million shares applies.  Further, the maximum number of ordinary 
shares with respect to which options may be granted under the 2008 Employee Option Plan, during any calendar year to any 
employee shall be 400,000 ordinary shares.  There is no individual limit under the 2008 Consultants Plan. No options may be 
granted under the 2008 Option Plans after February 14, 2027.

Each option granted under the 2008 Option Plans will be a nonqualified stock option, or NSO and not an incentive stock option 
as described in Section 422 of the Internal Revenue Code. Each grant of an option under the 2008 Options Plans will be evidenced 
by a Stock Option Agreement between the optionee and the Company. The exercise price will be specified in each Stock Option 
Agreement, however option prices will not be less than 100% of the fair market value of an ordinary share on the date the option 
is granted.

On January 17, 2003 the Company adopted the Share Option Plan 2003 (the “2003 Share Option Plan”) pursuant to which the 
Compensation and Organization Committee of the Board could grant options to officers and other employees of the Company or 
its subsidiaries for the purchase of ordinary shares.  An aggregate of 6.0 million ordinary shares were reserved under the 2003 
Share Option Plan; and, in no event could the number of ordinary shares issued pursuant to options awarded under this plan exceed 
10% of the outstanding shares, as defined in the 2003 Share Option Plan, at the time of the grant, unless the Board expressly 
determined otherwise. Further, the maximum number of ordinary shares with respect to which options could be granted under the 
2003 Share Option Plan during any calendar year to any employee was 400,000 ordinary shares. The 2003 Share Option Plan 
expired on January 17, 2013.  No new options may be granted under this plan.

Share option awards are granted with an exercise price equal to the market price of the Company’s shares at date of grant. Share 
options typically vest over a period of five years from date of grant and expire eight years from date of grant. The maximum 
contractual term of options outstanding at December 31, 2018 is eight years.

Item 10. Additional Information.

Constitution 

We hereby incorporate by reference our Constitution, as amended, located under the heading “Constitution of the Company” in 
Exhibit 3.1.

The following is a summary of certain provisions of the current Constitution of the Company. This summary does not purport to 
be complete and is qualified in its entirety by reference to the complete text of the Constitution of the Company, which are included 
as an exhibit to this annual report.

Objects
The  Company  is  incorporated  under  the  name  ICON plc,  and  is  registered  in  Ireland  under  registered  number 145835.  The 
Company's objects, which are detailed in the Constitution of the Company, are broad and include, but are not limited to, the carrying 
on the business of an investment holding company.

Directors
Subject to certain exceptions, Directors may not vote on matters in which they have a material interest. Any Director who holds 
any executive office, serves on any committee or otherwise performs services, which, in the opinion of the Directors, are outside 
the scope of the ordinary duties of a Director, may be paid such extra remuneration as the Directors may determine. The Directors 
may  exercise  all  the  powers  of  the  Company  to  borrow  money. These  powers  may  be  amended  by  special  resolution  of  the 
shareholders. The Directors are not required to retire at any particular age. One-third of the Directors retire and offer themselves 
for re-election at each Annual General Meeting ("AGM") of the Company. The Directors to retire by rotation are those who have 
been longest in office since their last appointment or reappointment. As between persons who became or were appointed Directors 
on the same date, those to retire are determined by agreement between them or, otherwise, by lot. All of the shareholders entitled 
to attend and vote at the AGM may vote on the re-election of Directors. There is no requirement for Directors to hold shares set 
out in the Constitution.

Rights, Preferences and Dividends Attaching to Shares 
The Company has only one class of shares, Ordinary Shares with a par value of €0.06 per share. All such Ordinary Shares rank 
equally with respect to voting, payment of dividends and on any winding-up of the Company. Any dividend, interest or other sum 
payable to a shareholder that remains unclaimed for one year after having been declared may be invested by the Directors for the 
benefit of the Company until claimed. If the Directors so resolve, any dividend which has remained unclaimed for 12 years from 
the date of its declaration shall be forfeited and cease to remain owing by the Company. In the event of the Company being wound 
up, if the assets available for distribution among the Members shall be more than sufficient to repay the whole of the share capital 
paid up or credited as paid up at the commencement of the winding up, the excess shall be distributed among the Members in 
proportion to the capital at the commencement of the winding up paid up or credited as paid up on the said Ordinary Shares held 
by them respectively. An Ordinary Share shall be deemed to be a redeemable share in certain circumstances. The liability of 
shareholders to invest additional capital is limited to the amounts remaining unpaid on the shares held by them.

63

 
Action Necessary to Change the Rights of Shareholders 
The rights attaching to shares in the Company may be varied by special resolutions passed at class meetings of that class of 
shareholders of the Company.

Annual and General Meetings
The AGM shall be held in such place and at such time as shall be determined by the board, but no more than 15 months shall pass 
between the dates of consecutive AGMs. Directors may call an Extraordinary General Meeting (“EGM”) at any time. The members, 
in accordance with the Constitution of the Company and Irish Company law, may also requisition EGM’s. Notice of the AGM or 
an EGM passing any special resolution must be given at least 21 clear days prior to the scheduled date and, in the case of any 
other general meeting, not less than 14 clear days’ notice. All holders of Ordinary Shares are entitled to attend, speak at and vote 
at general meetings of the Company.

Limitations on the Right to Own Shares 
There are no limitations on the right to own shares in the Constitution of the Company.

Disclosure of Share Ownership 
Under Irish law, the Company can require parties to disclose their interests in shares. The Constitution of the Company entitle the 
Directors to require parties to provide details regarding their identity and the nature and extent of any interest which such parties 
hold in Ordinary Shares. Under Irish law, if a party acquires or disposes of Ordinary Shares so as to bring his interest above or 
below 3% of the total issued share capital of the Company, he must notify the Company of that. The Company would also need 
to be notified of the acquisition by an existing substantial (i.e. 3% plus) shareholder, of every movement of one whole percentage 
integer (e.g. 3.9% to 4.1% but not 4.1% to 4.9%) or more.

Other Provisions of the Constitution
There are no provisions in the Constitution of the Company:

(i) delaying or prohibiting a change in the control of the Company, but which operate only with respect to a merger, acquisition 
or corporate restructuring;

(ii) discriminating against any existing or prospective holder of shares as a result of such shareholder owning a substantial number 
of shares; or

(iii) governing changes in capital, in each case, where such provisions are more stringent than those required by law.

Material Contracts

Not applicable.

Exchange Controls and Other Limitations Affecting Security Holders 

Irish exchange control regulations ceased to apply from and after December 31, 1992. Except as indicated below, there are no 
restrictions  on  non-residents  of  Ireland  dealing  in  domestic  securities,  which  includes  shares  or  depository  receipts  of  Irish 
companies. Except as indicated below, dividends and redemption proceeds also continue to be freely transferable to non-resident 
holders of such securities.

The Financial Transfers Act, 1992 gives power to the Minister for Finance of Ireland to make provision for the restriction of 
financial transfers between Ireland and other countries and persons. Financial transfers are broadly defined, and include all transfers 
which would be movements of capital or payments within the meaning of the treaties governing the European Communities. The 
acquisition or disposal of shares issued by an Irish incorporated company and associated payments may fall within this definition. 
In addition, dividends or payments on redemption or purchase of shares and payments on a liquidation of an Irish incorporated 
company would fall within this definition.

The Financial Transfers Act, 1992 prohibits financial transfers involving a number of persons, entities and bodies, which is subject 
to amendment on an ongoing, regular basis and currently includes, but is not limited to: certain persons and activities in Sudan,

Taxation

General

The following discussion is based on existing Irish tax law, Irish court decisions and the practice of the Revenue Commissioners 
of Ireland, and the convention between the United States and Ireland for the Avoidance of Double Taxation and the Prevention of 
Fiscal Evasion with respect to income and capital gains (the "Treaty"). This discussion does not purport to deal with the tax 
consequences of owning the ordinary shares for all categories of investors, some of which may be subject to special rules. Prospective 
purchasers of ordinary shares are advised to consult their own tax advisors concerning the overall tax consequences arising in 
their own particular situations under Irish law. Each prospective investor should understand that future legislative, administrative 
and judicial changes could modify the tax consequences described below, possibly with retroactive effect.

As used herein, the term "U.S. Holder" means a beneficial owner of ordinary shares that (i) owns the ordinary shares as capital 
assets; (ii) is a U.S. citizen or resident, a U.S. corporation, an estate the income of which is subject to U.S. federal income taxation 
regardless of its source or a trust that meets the following two tests: (A) a U.S. court is able to exercise primary supervision over 
the administration of the trust, and (B) one or more U.S. persons have the authority to control all substantial decisions of the trust; 
and for the purpose of the discussion under Irish Taxation of U.S. Holders (A) is not a resident of, or ordinarily resident in, Ireland 
for the purposes of Irish tax; and (B) is not engaged in trade or business in Ireland through a permanent establishment.

AS USED HEREIN, REFERENCES TO THE ORDINARY SHARES SHALL INCLUDE SHARES HELD IN THE ACCOUNTS 
OF PARTICIPANTS THROUGH THE DEPOSITARY TRUST COMPANY (“THE DTC”).

Irish Taxation

Irish corporation tax on income

ICON is a public limited company incorporated and resident for tax purposes in Ireland by virtue of its place of central management 
and control being in Ireland.

Companies which are resident in the Republic of Ireland are subject to Irish corporation tax on their total profits (wherever arising 
and, generally, whether or not remitted to the Republic of Ireland). The question of residence, by virtue of management and control, 
is essentially one of fact. It is the present intention of the Company's management to continue to manage and control the Company 
from the Republic of Ireland, so that the Company will continue to be resident in the Republic of Ireland.

The standard rate of Irish corporation tax on trading income (with certain exceptions) is currently 12.5%.

A research and development tax credit is available in Ireland where an Irish resident company incurs qualifying expenditure on 
research and development activities. Qualifying expenditure incurred in a particular account period results in a tax credit of 25% 
of that expenditure.

Corporation tax is charged at the rate of 25% on a company's non-trading income and certain types of trading income not eligible 
for the lower rate of 12.5% referred to above.

Capital gains arising to an Irish resident company are liable to tax at 33%. However, a capital gains tax exemption is available in 
Ireland for qualifying Irish resident companies in respect of disposals of certain qualifying shareholdings.

The exemption from capital gains tax on the disposal of shares by an Irish resident company will apply where certain conditions 
are met. These conditions principally are:

•  The company claiming the exemption must hold (directly or indirectly) at least 5% of the ordinary share capital of the 
company in which the interest is being disposed of, throughout a continuous period of at least 12 months, within the two 
year period prior to disposal;

•  The shares being disposed of must be in a company, which at the date of disposal, is resident in a Member State of the 
European Communities or in a country with which Ireland has signed or made specific arrangements to sign a double 
tax agreement (together a “Relevant Territory”);

65

 
 
 
 
•  The shares must be in a company which is primarily a trading company or the company making the disposal together 

with its “5% plus subsidiaries” should be primarily a trading group; and

•  The shares must not derive the greater part of their value from land or mineral rights in the State.

Irish withholding tax on dividends

Unless specifically exempted, all dividends paid by the Company, will be subject to Irish withholding tax at the standard rate of 
income tax in force at the time the dividend is paid, which is currently 20%.

An individual shareholder who is neither resident nor ordinarily resident for tax purposes in Ireland, but is resident in a country 
with which Ireland has a double tax treaty, or in a member state of the European Union, other than Ireland (together, a Relevant 
Territory), will be exempt from withholding tax provided he or she makes the requisite declaration.

Irish resident corporate shareholders will be exempt from withholding tax. Where the shareholding held by the recipient Company, 
in the company paying the dividend is not 51% or greater a declaration must be made in order to avail of the exemption.

Non-Irish resident corporate shareholders will be exempt from withholding tax on the production of the appropriate certificates 
and declarations where they:

• 

• 

• 

• 

are resident in a Relevant Territory and are not controlled (directly or indirectly) by Irish residents;

are ultimately controlled (directly or indirectly) by residents of a Relevant Territory; or

have the principal class of their shares, or shares of a 75% parent, substantially and regularly traded on one or more 
recognized stock exchanges in a Relevant Territory (including Ireland) or Territories; or

are wholly owned by two or more companies, each of whose principal class of shares is substantially and regularly traded 
on one or more recognized stock exchanges in a Relevant Territory (including Ireland) or Territories.

U.S. holders of ordinary shares should note, however, that detailed documentation requirements may need to be complied with. 
Special arrangements are available in the case of an interest in shares held in Irish companies through a depositary or in accounts 
of participants through the DTC. In certain cases the depositary or the DTC can receive and pass on a dividend from an Irish 
company without deducting withholding tax, provided the depositary or the DTC is a qualifying intermediary, and provided the 
person beneficially entitled to the distribution would meet the same conditions outlined above for the withholding tax exemption 
to apply and has provided the qualifying intermediary with the appropriate declarations. The depositary or the DTC shall be 
regarded as a qualifying intermediary provided the following conditions are met:

• 

• 

• 

the depositary or the DTC is resident in a Relevant Territory; and

the depositary or the DTC have entered into a qualifying intermediary agreement with the Irish tax authorities; and

the depositary or the DTC have been authorized by the Irish Revenue Commissioners as a qualifying intermediary and 
such authorization has not expired or been revoked.

Irish income tax on dividends

Irish resident or ordinarily resident shareholders will generally be liable to Irish income tax on dividend income at their marginal 
rate of income tax. This income may also be liable to Pay Related Social Insurance (“PRSI”) of up to 4% and the Universal Social 
Charge (“USC”) of up to 11% (up to 15% in total).

Under certain circumstances, non-Irish resident shareholders will be subject to Irish income tax on dividend income. This liability 
is limited to tax at the standard rate of 20% and therefore, where withholding tax has been deducted, this will satisfy the tax liability. 
No PRSI or USC should apply in these circumstances.

However, a non-Irish resident shareholder will not have an Irish income tax liability on dividends from the Company if the holder 
is neither resident nor ordinarily resident in the Republic of Ireland and the holder is:

66

• 

• 

• 

• 

• 

an individual resident in the U.S. or in a Relevant Territory;

a corporation that is ultimately controlled by persons resident in the U.S. or in a Relevant Territory;

a corporation whose principal class of shares (or its 75% or greater parent’s principal class of shares) is substantially and 
regularly traded on a recognized stock exchange in an EU country or in a Relevant Territory;

a corporation resident in another EU member state or in a Relevant Territory, which is not controlled directly or indirectly 
by Irish residents; or

a corporation that is wholly owned by two or more corporations each of whose principal class of shares is substantially 
and regularly traded on a recognized stock exchange in an EU country or in a Relevant Territory.

U.S. Holders who do not qualify for the above income tax exemption may be able to obtain treaty benefits under the double tax 
treaty.

Irish domicile levy

Certain non-Irish resident individuals that are domiciled in Ireland will be subject to an annual levy of €200,000 if their Irish-
located property exceeds €5,000,000, their worldwide annual income exceeds €1,000,000 and their liability to Irish Income Tax 
in that year is less than €200,000.

Irish capital gains tax on disposal of shares

Irish resident or ordinarily resident shareholders will be liable to capital gains tax at 33% on gains arising from the disposal or 
part disposal of their shareholding.

A person who is not resident or ordinarily resident in Ireland, who has not been an Irish resident within the past five years and 
who does not carry on a trade in Ireland through a branch or agency will not be subject to Irish capital gains tax on the disposal 
of ordinary shares or shares held in accounts of participants through the DTC, so long as the shares do not derive the greater part 
of their value from Irish land or mineral rights.

There are provisions to subject a person who disposes of an interest in a company while temporarily being non-Irish resident, to 
Irish capital gains tax. This treatment will apply to Irish domiciled individuals:

•  who cease to be Irish resident;

•  who beneficially own the relevant assets when they cease to be resident;

• 

if there are not more than 5 years of assessment between the last year of Irish tax residence prior to becoming temporarily 
non-resident and the tax year that he/she resumes Irish tax residency;

•  who dispose of the relevant assets during this temporary non-residence; and

• 

the interest disposed of represents 5% or greater of the issued share capital of the company or is worth at least 
€500,000.

In these circumstances the person will be deemed, for Irish capital gains tax purposes, to have sold and immediately reacquired 
the interest in the company on the date of his or her departure and will be subject to tax at 33% of the taxable gain.

Irish capital acquisitions tax

Irish capital acquisitions tax (referred to as CAT) applies to gifts and inheritances. Subject to certain tax-free thresholds, gifts and 
inheritances are liable to tax at 33%.

Where a gift or inheritance is taken under a disposition made after December 1, 1999  it will be within the charge to CAT:

• 

to the extent that the property of which the gift or inheritance consists is situated in the Republic of Ireland at the date of 
the gift or inheritance;

67

•  where the person making the gift or inheritance is or was resident or ordinarily resident in the Republic of Ireland at the 

date of the disposition under which the gift or inheritance is taken;

• 

in the case of a gift taken under a discretionary trust where the person from whom the gift is taken was resident or ordinarily 
resident in the Republic of Ireland at the date he made the settlement, or at the date of the gift or, if he is dead at the date 
of the gift, at the date of his death; or

•  where the person receiving the gift or inheritance is resident or ordinarily resident in the Republic of Ireland at the date 

of the gift or inheritance. 

For these purposes a non-Irish domiciled individual will not be regarded as resident or ordinarily resident in the Republic of Ireland 
on a particular date unless they are resident or ordinarily resident in the Republic of Ireland on that date and have been resident 
for the 5 consecutive tax years immediately preceding the year of assessment in which the date falls.

The person who receives the gift or inheritance (“the beneficiary”) is primarily liable for CAT. In the case of an inheritance, where 
a beneficiary and personal representative of the deceased are both non-residents, a solicitor must be appointed to be responsible 
for paying inheritance tax. Taxable gifts or inheritances received by an individual since December 5, 1991 from donors in the 
same threshold class are aggregated and only the excess over a specified tax-free threshold is taxed. The tax-free threshold is 
dependent on the relationship between the donor and the donees and the aggregation since December 5, 1991 of all previous gifts 
and inheritances, within the same tax threshold.

The tax-free threshold amounts that apply are:

• 

• 

• 

€16,250 in the case of persons who are not related to one another;

€32,500 in the case of gifts or inheritances received from inter alia a brother or sister or from a brother or sister of a parent 
or from a grandparent; and

€320,000 in the case of gifts and inheritances received from a parent (or from a grandparent by a minor child of a deceased 
child) and specified inheritances received by a parent from a child for gifts or inheritances taken on or after October 10, 
2018. This threshold was €310,000 prior to October 10, 2018. 

Gifts and inheritances passing between spouses are exempt from CAT.

A gift or inheritance of ordinary shares or ADSs will be within the charge to Irish capital acquisitions tax, notwithstanding that 
the person from whom or by whom the gift or inheritance is received is domiciled or resident outside Ireland.

The Estate Tax Convention between Ireland and the United States generally provides for Irish capital acquisitions tax paid on 
inheritances in Ireland to be credited against U.S. Federal Estate tax payable in the United States and for tax paid in the United 
States to be credited against tax payable in Ireland, based on priority rules set forth in the Estate Tax Convention. The Estate Tax 
Convention does not apply to Irish capital acquisitions tax paid on gifts.

Irish stamp duty 

Irish stamp duty, which is a tax on certain documents, is payable on all transfers of ordinary shares (other than between spouses) 
whenever a document of transfer is executed. Where the transfer is attributable to a sale, stamp duty will be charged at a rate of 
1%, rounded to the nearest euro. The stamp duty is calculated on the amount or value of the consideration (i.e. purchase price) or, 
if the transfer is by way of a gift (subject to certain exceptions) or for consideration less than the market value, on the market value 
of the shares. Where the consideration for the sale is expressed in a currency other than euro, the duty will be charged on the euro 
equivalent calculated at the rate of exchange prevailing on the date of the transfer.

Transfers through the DTC of book entry interests in shares are not subject to Irish stamp duty.

A transfer of ordinary shares by a shareholder to a depositary or custodian for deposit and a transfer of ordinary shares from the 
depositary or the custodian for the purposes of the withdrawal of the underlying ordinary shares in accordance with the terms of 
a deposit agreement will be stampable at the ad valorem rate if the transfer relates to a sale, a contemplated sale, a gift or any other 
change in the beneficial ownership of such ordinary shares. However transfers of ordinary shares into or out of the DTC are not 
subject to Irish stamp duty provided that no change in beneficial ownership of the shares has occurred and provided a contract for 
sale in respect of the transferring shares is not in place.

68

The person accountable for payment of stamp duty is normally the transferee or, in the case of a transfer by way of gift, or for a 
consideration less than the market value, all parties to the transfer.

Transfers of ordinary shares between associated companies (broadly, companies within a 90% group relationship and subject to 
the satisfaction of certain conditions) are exempt from stamp duty in the Republic of Ireland. In the case of transfers of ordinary 
shares where no beneficial interest passes (e.g. a transfer of shares from a beneficial owner to his nominee), no stamp duty arises.

No stamp duty shall arise on the transfer of ordinary shares where the consideration for the transfer does not exceed €1,000, 
provided the instrument contains a statement certifying that the transaction does not form part of a larger transaction or a series 
of larger transactions, in respect of which the amount of the total consideration attributable to the shares would exceed €1,000.

Documents on Display 

We are subject to the informational requirements of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”) and 
file  reports  and  other  information  with  the  SEC. The  SEC  maintains  a  website  that  contains  reports,  proxy  and  information 
statements and other information regarding registrants that file electronically with the SEC at http://www.sec.gov.  

We “incorporate by reference” information that we file with the SEC, which means that we can disclose important information to 
you by referring you to those documents. The information incorporated by reference is an important part of this report and more 
recent information automatically updates and supersedes more dated information contained or incorporated by reference in this 
report. Our SEC file number for Exchange Act reports is 333-08704.

As a foreign private issuer, we are exempt from certain rules under the Exchange Act, including prescribing the furnishing and 
content of proxy statements to shareholders.

We will provide without charge to each person, including any beneficial owner, on the written or oral request of such person, a 
copy of any or all documents referred to above which have been or may be incorporated by reference in this report (not including

Exemptions From Corporate Governance Listing Requirements Under the NASDAQ Marketplace Rules 

NASDAQ may provide exemptions from certain NASDAQ corporate governance standards to a foreign private issuer if, among 
other reasons those standards are contrary to a law, rule or regulation of a public authority exercising jurisdiction over such issuer 
or contrary to generally accepted business practices in the issuer’s home country of domicile, provided, that, the foreign private 
issuer properly notifies NASDAQ and makes the required disclosure except to the extent that such exemptions would be contrary 
to United States federal securities laws. 

The exemptions that the Company relies on, and the practices the Company adheres to, are as follows:

•  The Company is exempt from provisions set forth in NASDAQ Rule 5620(c), which requires each issuer (other than limited 
partnerships) to provide for a quorum in its by-laws for any meeting of the holders of common stock, which shall in no 
case be less than 33.33% of the outstanding shares of the issuer’s common voting stock. The Company’s Constitution 
requires that only 3 members be present, in person or by proxy, at a shareholder meeting to constitute a quorum.  This 
quorum requirement is in accordance with Irish law and generally accepted business practices in Ireland.

•  The Company is exempt from provisions set forth in NASDAQ Rule 5635(c) which requires (other than for certain specified 
exceptions) shareholder approval prior to the establishment or material amendment of a stock option or purchase plan or 
other equity compensation arrangement made or materially amended, pursuant to which stock may be acquired by officers, 
Directors, employees or consultants.  Irish law does not require shareholder approval with respect to equity compensation 
arrangements. Accordingly, the 2013 Employees Restricted Share Unit Plan and the amendments to the Employee Share 
Option Plan 2008 and Consultants Share Option Plan 2008 were adopted by the Board of Directors without shareholder 
approval.

• 

The Company is exempt from provisions set forth in NASDAQ Rule 5605(b)(2), which requires independent Directors 
to hold regularly scheduled meetings at which only independent Directors are present.  Irish law does not require independent 
Directors to hold regularly scheduled meetings at which only independent Directors are present. The Company holds 
regularly scheduled meetings which all of the Directors may attend and the Lead Independent Director may call meetings 

69

of  the  independent  directors  and  non-employee  directors  of  the  Board,  as  appropriate,  in  accordance  with  the  Lead 
Independent Director Charter.   

Item 11 . Quantitative and Qualitative Disclosures about Market Risk.

The principal market risks (i.e. risk of loss arising from adverse changes in market rates and prices) to which we are exposed 
include foreign currency risk and interest rate risk.

Foreign Currency Exchange Risk

We are subject to a number of foreign currency risks given the global nature of our operations. The principal foreign currency 
risks to which the business is subject to includes both foreign currency translation risk and foreign currency transaction risk.

Although domiciled in Ireland, we report our results in U.S. dollars. As a consequence the results of our non-U.S. based operations, 
when translated into U.S. dollars, could be affected by fluctuations in exchange rates between the U.S. dollar and the currencies 
of those operations.

We are also subject to foreign currency transaction exposures as the currency in which our contracts are priced can be different 
from the currencies in which costs relating to those contracts are incurred. Our operations in the United States are not materially 
exposed to such currency differences as the majority of revenues and costs are in U.S. dollars. However, outside the United States 
the multinational nature of our activities means that contracts may be priced in a single currency, most often U.S. dollars, or euro, 
while costs arise in a number of currencies, depending, among other things, on which of our offices provide staff for the contract 
and the location of investigator sites. Although many such contracts benefit from some degree of natural hedging due to the 
matching of contract revenues and costs in the same currency, where costs are incurred in currencies other than those in which 
contracts are priced, fluctuations in the relative value of those currencies could have a material effect on our results of operations. 
We regularly review our foreign currency exposures and enter into forward currency contracts to manage our exposure. We had 
no open foreign currency contracts at December 31, 2018.

We are exposed to interest rate risk in respect of our cash and cash equivalents and available for sale investments. Our treasury 
function actively manages our available cash resources and invests significant cash balances to try to ensure optimum returns for 
the Company. Financial instruments are classified either as cash and cash equivalents or available for sale investments depending 
upon the maturity of the related investment. Funds may be invested in the form of floating rate notes and medium term minimum 
“A-” rated corporate securities. We may be subject to interest rate risk in respect of interest rate changes on amounts invested. 
Interest rate risk is managed by monitoring the composition of the Company’s investment portfolio on an ongoing basis having 
regard to current market interest rates and future trends.

In December 2015 we issued $350 million in the private placement market, the rate on these senior notes is fixed at 3.64% for the 
five year term. The interest rate is further reduced by an interest rate cash flow hedge which was entered into in advance of the 
rate fixing date. This cash flow hedge was deemed to be fully effective in accordance with Financial Accounting Standards Board 
(“FASB”) ASC 815 “Derivatives and Hedging”.  The realized gain related to this derivative is recorded within other comprehensive 
income and is amortized over the life of the Senior Notes. The effective rate on our 5 year Senior Notes is fixed at 3.37%. ICON 
did not have any short term borrowings in 2018 and were not exposed to changes in market interest rates as a result.

On October 3, 2016 the Company commenced a previously announced share buyback program of up to $400 million. During the 
year  ended  December 31,  2018,  the  Company  redeemed  a  total  of  1,008,162  ordinary  shares  under  this  program  for  total 
consideration of $129.0 million. At December 31, 2018 a total of 4,026,576 ordinary shares were redeemed by the Company under 
this buyback program for a total consideration of $372.1 million 

On January 8, 2019 the Company announced a share buyback program of up to 1 million shares to be executed opportunistically 
during 2019 depending on cash commitments. All ordinary shares that are redeemed under the buyback program will be canceled 
in  accordance  with  the  constitutional  documents  of  the  Company  and  the  nominal  value  of  these  shares  transferred  to  an 
undenominated capital fund as required under Irish Company law.  

73

 
 
 
Under the repurchase programs, a broker purchased the Company's shares from time to time on the open market or in privately 
negotiated transactions in accordance with agreed terms and limitations. The programs are designed to allow share repurchases 
during periods when the Company would ordinarily not be permitted to do so because it may be in possession of material non-
public or price-sensitive information, applicable insider trading laws or self-imposed trading blackout periods. The Company's 
instructions to the broker were irrevocable and the trading decisions in respect of the repurchase programs were made independently 
of and uninfluenced by the Company. The Company confirms that on entering the share repurchase plans it had no material non-
public, price-sensitive or inside information regarding the Company or its securities. Furthermore, the Company will not enter 
into additional plans whilst in possession of such information. The timing and actual number of shares acquired by way of the 
redemption will be dependent on market conditions, legal and regulatory requirements and the other terms and limitations contained 
in  the  programs.  In  addition,  acquisitions  under  the  programs  may  be  suspended  or  discontinued  in  certain  circumstances  in 
accordance with the agreed terms. Therefore, there can be no assurance as to the timing or number of shares that may be acquired 
under the programs.

Management's Report on Internal Control over Financial Reporting

Management 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 Securities Exchange Act of 1934.

The Company's internal control over financial reporting is a process designed by, or under the supervision of, the Company's 
executive and financial officers and effected by the Company's board of Directors, management and other personnel, to provide 
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting 
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, 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 
authorization of management and Directors of the company; and (iii) provide reasonable assurance regarding prevention or timely 
detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial 
statements.

Because of the inherent limitation due to, for example, the potential for human error or circumvention of control, 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 assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2018. In 
making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission 
(COSO) in Internal Control – Integrated Framework 2013. Based upon the assessment performed, we determined that, as of 
December 31, 2018 the Company's internal control over financial reporting was effective. Effective January 1, 2018, we adopted 
the new revenue standard, ASC Topic 606, Revenue from Contracts with Customers, and implemented a new clinical trial service 
revenue process and internal controls to assist in the application of the new revenue standard. There have been no changes in the 
Company's internal control over financial reporting during 2018 that have materially affected, or are reasonably likely to affect 
materially, the Group's internal control over financial reporting.

KPMG, an independent registered public accounting firm, has audited the consolidated financial statements of ICON plc and 
subsidiaries as of and for the year ended December 31, 2018, included herein, and has issued an audit report on the effectiveness 
of our internal control over financial reporting, which is included on pages 77 and 78 of Form - 20F.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors

ICON plc:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of ICON plc and subsidiaries ("the Company") as of 
December 31, 2018 and 2017, the related consolidated statements of operations, comprehensive income, shareholders' equity 
and comprehensive income, and cash flows for each of the years in the three-year period ended December 31, 2018, and the 
related notes (collectively, the “consolidated financial statements”). In our opinion, the consolidated financial statements 
present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results 
of its operations and its cash flows for each of the years in the three-year period ended December 31, 2018, in conformity with 
U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(“PCAOB”), 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 and our report dated March 1, 2019 expressed an unqualified opinion on the effectiveness of the Company's internal 
control over financial reporting.

Change in Accounting Principle 

As discussed in Note 2 to the consolidated financial statements, effective January 1, 2018, the Company has changed its method 
of accounting for revenue recognition, due to the adoption of ASC Topic 606, Revenue from Contracts with Customers.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an 
opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the 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 
audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether 
due to error or fraud. Our audits 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. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 1990.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors

ICON plc:

Opinion on Internal Control Over Financial Reporting 

We have audited ICON plc and subsidiaries’ (the “Company”) 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. 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 Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
("PCAOB"), the consolidated balance sheets of the Company as of December 31, 2018 and 2017, the related consolidated statements 
of operations, comprehensive income, shareholders' equity and comprehensive income, and cash flows for each of the years in 
the three-year period ended December 31, 2018, and the related notes, (collectively, the “consolidated financial statements”), and 
our report dated March 1, 2019 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment 
of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal 
Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial 
reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material 
respects. Our audit 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 audit also included performing such other procedures as we considered necessary 
in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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

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

ICON plc
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1. Description of business 

ICON plc and its subsidiaries ("the Company" or "ICON") is a clinical research organization ("CRO"), providing outsourced 
development services on a global basis to the pharmaceutical, biotechnology and medical device industries. We specialize in the 
strategic development, management and analysis of programs that support all stages of the clinical development process from 
compound selection to Phase I-IV clinical studies. Our vision is to be the Global CRO partner of choice in drug development by 
delivering best in class information, solutions and performance in clinical and outcomes research.

We believe that we are one of a select group of CROs with the expertise and capability to conduct clinical trials in most major 
therapeutic areas on a global basis and have the operational flexibility to provide development services on a stand-alone basis or 
as part of an integrated "full service" solution. At December 31, 2018 we had approximately 13,670 employees, in 89 locations 
in 37 countries. During the year ended December 31, 2018, we derived approximately 34.5%, 55.7% and 9.8% of our net revenue 
in the United States, Europe and Rest of World, respectively.

We began operations in 1990 and have expanded our business predominately through internal growth, together with a number of 
strategic  acquisitions  to  enhance  our  capabilities  and  expertise  in  certain  areas  of  the  clinical  development  process.  We  are 
incorporated in Ireland and our principal executive office is located at: South County Business Park, Leopardstown, Dublin 18, 
Republic of Ireland. The contact telephone number of this office is +353 1 2912000.

2. Significant Accounting Policies

The accounting policies noted below were applied in the preparation of the accompanying financial statements of the Company 
and are in conformity with accounting principles generally accepted in the United States.

(a)   Basis of consolidation

The consolidated financial statements include the financial statements of the Company and all of its subsidiaries. All significant 
intercompany profits, transactions and account balances have been eliminated. The results of subsidiary undertakings acquired in 
the period are included in the Consolidated Statement of Operations from the date of acquisition.

(b)   Use of estimates

The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires 
management to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent 
assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported 
period. Actual results could differ from those estimates. The principal management estimates and judgments used in preparing the 
financial statements relate to revenue recognition and taxation.

(c)   Revenue recognition

The Company primarily earns revenues by providing a number of different services to its customers. These services, which are 
integral  elements  of  the  clinical  development  process,  include  clinical  trials  management,  consulting,  contract  staffing,  and 
laboratory services. Contracts range in duration from a number of months to several years.

85

 
 
ASC 606 - Revenue from Contracts with Customers (year-ended December 31, 2018)

ICON adopted ASC 606 ' 'Revenue from Contracts with Customers' standard using the cumulative effect transition method. Under 
this transition method, ICON has applied the new standard as at the date of initial application (i.e. January 1, 2018), without 
restatement of comparative amounts. The cumulative effect of initially applying the new standard (to revenue, costs and tax) is 
recorded as an adjustment to the opening balance of equity at the date of initial application. The comparative information has not 
been adjusted and therefore continues to be reported under ASC 605 ‘Revenue Recognition’ and therefore in accordance with 
previous accounting policies. See note 26 Impact of change in accounting policies for details of the impact of adoption of the new 
accounting policy.   

The new standard requires application of five steps: (1) identify the contract(s) with a customer; (2) identify the performance 
obligation in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in 
the contract; and (5) recognize revenue when (or as) the entity satisfies the performance obligation.  

Clinical trial service revenue

The most significant impact of application of the standard relates to our assessment of performance and percentage of completion 
in respect of our clinical trial service revenue. Prior to application of ASC 606, the revenue attributable to performance was 
determined based on both input and output methods of measurement on a percentage of completion basis. We have concluded that 
under the new standard, a clinical trial service is a single performance obligation satisfied over time i.e. the full service obligation 
in respect of a clinical trial (including those services performed by investigators and other parties) is considered a single performance 
obligation. Promises offered to the customer are not distinct within the context of the contract. We have concluded that ICON is 
the contract principal in respect of both direct services and in the use of third parties (principally investigator services) that support 
the clinical research project. The transaction price is determined by reference to the contract or change order value (total service 
revenue and pass-through/ reimbursable expenses) adjusted to reflect a realizable contract value. Revenue is  recognized as the 
single performance obligation is satisfied. The progress towards completion for clinical service contracts is measured based on 
an input measure being total project costs (inclusive of third party costs) at each reporting period.

Contracting services revenue
On evaluation of the principles at (1) - (5) set-out above in respect of ASC 606, the Company has availed of the practical expedient 
which results in recognition of revenue on a right to invoice basis. Application of the practical expedient reflects the right to 
consideration from the customer in an amount that corresponds directly with the value to the customer of the performance completion 
to date. This reflects hours performed by contract staff. 

Consulting services revenue
On application of the ASC 606 'Revenue from Contracts with Customers' principles at (1) - (5) set-out above, we have concluded 
that  our  consulting  services  contracts  represent  a  single  performance  obligation  satisfied  over  time. The  transaction  price  is 
determined by reference to contract or change order value.  Revenue is recognized as the performance obligation is satisfied. The 
progress towards completion for consulting contracts is measured based on total project inputs (time) at each reporting period.  

Laboratory services revenue
Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the 
products or services are transferred to the customer. Revenue for laboratory services is measured as the amount of consideration 
we expect to receive in exchange for transferring products or services. Where contracts with customers contain multiple performance 
obligations, the transaction price is allocated to each performance obligation based on the estimated relative selling price of the 
promised good or service. Service revenue is recognized over time as the services are delivered to the customer based on the extent 
of progress towards completion of the performance obligation. The determination of the methodology to measure progress requires 
judgment and is based on the nature of services provided. This requires an assessment of the transfer of value to the customer.  
The right to invoice measure of progress is generally related to rate per unit contracts, as the extent of progress towards completion 
is measured based on discrete service or time-based increments, such as samples tested or labor hours incurred. Revenue is recorded 
in the amount invoiced since that amounts corresponds to the value of the Company's performance and the transfer of value to the 
customer.   

ASC 605 - Revenue recognition (years ended December 31, 2017 and December 31, 2016)

Revenue for services, as rendered, is recognized only after persuasive evidence of an arrangement exists, the sales price is fixed 
or determinable and collectability is reasonably assured.

86

Clinical trials management revenue is recognized on a proportional performance method. Depending on the contractual terms 
revenue is either recognized on the percentage of completion method based on the relationship between hours incurred and the 
total estimated hours of the trial or on the unit of delivery method. Contract costs equate to the product of labor hours incurred 
and compensation rates. For the percentage of completion method, the input (effort expended) method has been used to measure 
progress towards completion as there is a direct relationship between input and productivity. Contract revenue is the product of 
the aggregated labor hours required to complete the specified contract tasks at the agreed contract rates. The Company regularly 
reviews the estimate of total contract time to ensure such estimates remain appropriate taking into account actual contract stage 
of completion, remaining time to complete and any identified changes to the contract scope. Remaining time to complete depends 
on the specific contract tasks, the complexity of the contract and can include geographical site selection and initiation, patient 
enrollment, patient testing and level of results analysis required. While the Company may routinely adjust time estimates, the 
Company's estimates and assumptions historically have been accurate in all material respects in the aggregate. Where revenue is 
recognized on the unit of delivery method, the basis applied is the number of units completed as a percentage of the total number 
of contractual units.

Consulting revenue is recognized on a fee-for-service basis as each hour of the related service is performed. 

Contract staffing revenue is recognized on a fee-for-service basis, over the time the related service is performed, or in the case of 
permanent placement, once the candidate has been placed with the client. 

Laboratory service revenue is recognized on a fee-for-service basis. The Company accounts for laboratory service contracts as 
multiple element arrangements, with contractual elements comprising laboratory kits and laboratory testing, each of which can 
be sold separately. Sales prices for contractual elements are determined by reference to objective and reliable evidence of their 
sales price. Revenues for contractual elements are recognized on the basis of the number of deliverable units completed in the 
period.

Informatics revenue is recognized on a fee-for-service basis. Informatics contracts are treated as multiple element arrangements, 
with contractual elements comprising license fee revenue, support fee revenue and revenue from software services, each of which 
can be sold separately. Sales prices for contractual elements are determined by reference to objective and reliable evidence of their 
sales price. 

License and support fee revenues are recognized rateably over the period of the related agreement. Revenue from software services 
is recognized using the percentage of completion method based on the relationship between hours incurred and the total estimated 
hours required to perform the service.

Contracts generally contain provisions for renegotiation in the event of changes in the scope, nature, duration, or volume of services 
of the contract. Renegotiated amounts are recognized as revenue by revision to the total contract value arising as a result of an 
authorized customer change order.

(d)   Third party costs (Reimbursable expenses)

Reimbursable  expenses  comprise  investigator  payments  and  certain  other  costs  which  are  reimbursed  by  clients  under  terms 
specific to each contract to the investigators. Third party costs (Reimbursable expenses) and the related revenue were separately 
presented on the face of the Consolidated Statement of Operations for periods up to and including the year-ended December 31, 
2017.  See sections (c) and (e) for accounting policy in respect of the treatment of activity relating to reimbursable expenses on 
revenue (c) and costs (e) on adoption of ASC 606 'Revenue from Contracts with Customers'.  

(e)   Direct costs

Direct costs consist of compensation, associated employee benefits and share-based payments for project-related employees and 
other direct project-related costs.

On adoption of ASC 606 'Revenue from Contracts with Customers', reimbursable expenses are presented within direct costs. This 
presentation is to align the presentation of costs with our assessment that our clinical trial service is a single performance obligation 
satisfied over time i.e. the full service obligation is in respect of a clinical trial (including those services performed by investigators 
and other parties) is considered a single performance obligation. Reimbursable expenses are recorded once the activity which 
forms the basis for the cost has occurred. Direct costs for the year-ended December 31, 2018 are therefore inclusive of third party 
costs of $702.8 million.    

87

Investigator payment costs are recorded and reported reflecting investigator activity over the life of the contract. Investigator 
payments are made based on predetermined contractual arrangements. Payments may differ from the recording and reporting of 
the expense which is based on activity.

(f)   Advertising costs

All costs associated with advertising and promotion are expensed as incurred. The advertising and promotion costs were $6,516,637, 
$6,744,333 and $7,167,050 for the years ended December 31, 2018, December 31, 2017 and December 31, 2016 respectively.

(g)   Foreign currencies and translation of subsidiaries

The Company's financial statements are prepared in United States dollars. Transactions in currencies other than United States 
dollars are recorded at the rate ruling at the date of the transaction. Monetary assets and liabilities denominated in currencies other 
than United States dollars are translated into United States dollars at exchange rates prevailing at the Balance Sheet date. Adjustments 
resulting from these translations are charged or credited to income. Amounts charged or credited to the Consolidated Statement 
of Operations for the years ended December 31, 2018, December 31, 2017 and December 31, 2016 were as follows:

The financial statements of subsidiaries with other functional currencies are translated at period end rates for the Consolidated 
Balance Sheet and average rates for the Consolidated Statement of Operations. Translation gains and losses arising are reported 
as a movement on accumulated other comprehensive income. Foreign currency transaction gains and losses are reported in other 
comprehensive income rather than through income where the foreign currency transaction is 'long-term investment' in nature i.e. 
settlement is not planned or anticipated in the foreseeable future.  

(h)   Disclosure of fair value of financial instruments

Cash, cash equivalents, unbilled revenue, other receivables, available for sale investments, prepayments and other current assets, 
accounts  receivable,  accounts  payable,  investigator  payments,  payments  on  account,  accrued  liabilities,  accrued  bonuses  and 
income taxes payable have carrying amounts that approximate fair value due to the short term maturities of these instruments. 
Other liabilities' carrying amounts approximate fair value based on net present value of estimated future cash flows. Debt is 
measured at historical cost.  

Financial instruments are measured in the Consolidated Balance Sheet at fair value using a fair value hierarchy of valuation inputs. 
The hierarchy prioritizes the inputs into three levels based on the extent to which inputs used in measuring fair value are observable 
in the market. Each fair value measurement is reported in one of three levels, which is determined by the lowest level input that 
is significant to the fair value measurement in its entirety. These levels are:

Level 1:

Inputs are based upon unadjusted quoted prices for identical instruments traded in active markets.

Level 2:

Inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar 
instruments  in  markets  that  are  not  active  and  model-based  valuation  techniques  for  which  all  significant 
assumptions are observable in the market or can be corroborated by observable market data for substantially the 
full term of the assets or liabilities.

Level 3:

Inputs  are  generally  unobservable  and  typically  reflect  management’s  estimates  of  assumptions  that  market 
participants would use in pricing the asset or liability.

88

 
 
 
 
 
 
 
 
 
 
 
The Group's Senior notes (private placement debt) is carried at $350.0 million (prior to related financing costs).  The carrying 
value at December 31, 2018, closely approximates fair value.  

The Company classifies its investments in short term debt or equity investments as available for sale, as it does not actively trade 
such securities nor does it intend to hold them to maturity. The fair value of short term investments are represented by level 1 fair 
value measurements – quoted prices in active markets for identical assets. The unrealized movements in fair value are recognized 
in equity until disposal or sale, at which time, those unrealized movements from prior periods are recognized in Consolidated 
Statement of Operations. Losses other than temporary, which reduce the carrying amount below cost are recognized in Consolidated 
Statement of Operations.

(i)   Business combinations

The cost of a business combination is measured as the aggregate of the fair values at the date of exchange of assets given, liabilities 
incurred or assumed and equity instruments issued in exchange for control. Where a business combination agreement provides 
for an adjustment to the cost of the acquisition which is contingent upon future events, the amount of the estimated adjustment is 
recognized  at  the  acquisition  date  at  the  fair  value  of  the  contingent  consideration. Any  changes  to  this  estimate  outside  the 
measurement period will depend on the classification of the contingent consideration. If the contingent consideration is classified 
as equity it shall not be re-measured and the settlement shall be accounted for within equity. If the contingent consideration is 
classified  as  a  liability  any  adjustments  will  be  accounted  for  through  the  Consolidated  Statement  of  Operations  or  Other 
Comprehensive Income depending on whether the liability is considered a financial instrument.

The assets, liabilities and contingent liabilities of businesses acquired are measured at their fair values at the date of acquisition. 
In the case of a business combination which is completed in stages, the fair values of the identifiable assets, liabilities and contingent 
liabilities are determined at the date of each exchange transaction. When the initial accounting for a business combination is 
determined provisionally, any subsequent adjustments to the provisional values allocated to the identifiable assets, liabilities and 
contingent  liabilities  are  made  within  twelve  months  of  the  acquisition  date  and  presented  as  adjustments  to  goodwill  in  the 
reporting period in which the adjustments are determined.

(j)   Goodwill and Impairment

Goodwill represents the excess of the cost of acquired entities over the net amounts assigned to assets acquired and liabilities 
assumed. Goodwill primarily comprises acquired workforce in place which does not qualify for recognition as an asset apart from 
goodwill. Goodwill is stated net of any provision for impairment. The Company tests goodwill annually for any impairments or 
whenever events occur which may indicate impairment. The Company applied the provisions of ASU 2017-04 with effect from 
January 1, 2018.  Under the amendment, the Company was required to perform its annual goodwill impairment test by comparing 
the fair value of a reporting unit with its carrying amount. An impairment charge would be recognized for any amount by which 
the carrying amount exceeds the reporting unit's fair value up to the amount of existing goodwill. The amendment allows an entity 
to perform a qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.  No impairment 
was recognized as a result of the impairment testing carried out for the years ended December 31, 2018, December 31, 2017 and 
December 31, 2016.

(k)   Intangible assets

Intangible assets are amortized on a straight line basis over their estimated useful life.

(l)   Cash and cash equivalents

Cash and cash equivalents include cash and highly liquid investments with initial maturities of three months or less and are stated 
at cost, which approximates market value.

(m)   Investments in debt, equity and other

Available for sale investments

The Company classifies short-term investments as available for sale in accordance with the terms of FASB ASC 320, Investments 
– Debt and Equity Securities. Realized gains and losses are determined using specific identification. The investments are reported 
at fair value, with unrealized gains or losses reported in a separate component of shareholders' equity. Any differences between 
the cost and fair value of the investments are represented by accrued interest and unrealized gains/losses.

89

Long term investments  

The Company classifies its interests in funds having considered the nature of its investment, the extent of influence over operating 
and financial decisions and the availability of readily determinable fair values. The Company determined that the interests in  funds 
at December 31, 2018 meet the definition of equity securities without readily determinable fair values. Effective from 1 January 
2018, the Company concluded that the interests held at December 31, 2018 qualify for the NAV practical expedient in ASC 820 
'Fair value measurements and disclosures'.  Any increases or decreases in fair value are recognized in net income in the period. 
These are therefore measured at Level 3 of the fair value hierarchy.  

(n) Accounts receivable, net

Accounts receivable are recorded at fair value less an allowance for doubtful accounts. The allowance is an estimate based on 
historical collection experience, current economic and market conditions, and a review of the current status of each customer's 
trade accounts receivable. Account balances are written-off against the allowance when the Group determines that it is probable 
that the receivable will not be recovered.

(o) Inventory

Inventory is valued at the lower of cost and net realizable value and after provisions for obsolescence. The cost of inventories 
comprises the purchase price and attributable costs, less trade discounts. At December 31, 2018 the carrying value of inventory, 
included within prepayments and other current assets on the Consolidated Balance Sheet, was $2.3 million (2017: $2.2 million).

(p) Property, plant and equipment

Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation of property, plant and equipment is 
computed using the straight line method based on the estimated useful lives of the assets as listed below: 

Building 
Computer equipment and software
Office furniture and fixtures
Laboratory equipment 
Motor vehicles

Years
40
2-8
8
5
5

Leasehold improvements are amortized using the straight line method over the estimated useful life of the asset or the lease term, 
whichever is shorter.

(q) Leased assets

Costs in respect of operating leases are charged to the Consolidated Statement of Operations on a straight line basis over the lease 
term.

Assets acquired under capital finance leases are included in the Consolidated Balance Sheet at the present value of the future 
minimum lease payments and are depreciated over the shorter of the lease term and their remaining useful lives. The corresponding 
liabilities are recorded in the Consolidated Balance Sheet and the interest element of the capital lease rental is charged to interest 
expense.

(r) Income taxes

The Company applies the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred 
tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement 
carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. 
Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which 
these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in 
tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation 
allowance to the amount more likely than not to be realized. The Company recognizes the effect of income tax positions only if 
those positions will more likely than not be sustained. Recognized income tax positions are measured at the largest amount of tax 

90

benefit that is greater than 50 percent likely of being realized upon settlement. Interest and penalties related to income taxes are 
included in income tax expense and classified with the related liability on the Consolidated Balance Sheet. The Company  accounts 
for the impact of GILTI (“global intangible low-taxed income”) as a period item in the period it arises and has therefore not 
provided for deferred taxes in respect of this item.

(s)   Government grants

Government grants received relating to capital expenditures are shown as deferred income and credited to income on a basis 
consistent with the depreciation policy of the relevant assets. Grants relating to categories of operating expenditures are credited 
to income in the period in which the expenditure to which they relate is charged.

Under the grant agreements amounts received may become repayable in full should certain circumstances specified within the 
grant agreements occur, including downsizing by the Company, disposing of the related assets, ceasing to carry on its business or 
the appointment of a receiver over any of its assets. The Company has not recognized any loss contingency having assessed as 
remote the likelihood of these events arising.

(t)   Research and development credits

Research and development credits are available to the Company under the tax laws in certain jurisdictions, based on qualifying 
research and development spend as defined under those tax laws. Research and development credits are generally recognized as 
a reduction of income tax expense. However, certain tax jurisdictions provide refundable credits that are not wholly dependent on 
the Company's ongoing income tax status or income tax position. In these circumstances the benefit of these credits is not recorded 
as a reduction to income tax expense, but rather as a reduction of operating expenditure.

(u)   Pension costs

The Company contributes to defined contribution plans covering all eligible employees. The Company contributes to these plans 
based upon various fixed percentages of employee compensation and such contributions are expensed as incurred.

The Company operates, through two subsidiaries, a defined benefit plan for certain of its United Kingdom and Swiss employees. 
The Company accounts for the costs of these plans in accordance with ASC 715-30. These plans are presented in accordance with 
the requirements of FASB ASC 715-60 Defined Benefit Plans – Other Post retirement.

(v)   Net income per ordinary share

Basic net income per ordinary share has been computed by dividing net income available to ordinary shareholders by the weighted 
average number of ordinary shares outstanding during the period. Diluted net income per ordinary share is computed by adjusting 
the weighted average number of ordinary shares outstanding during the period for all potentially dilutive ordinary shares outstanding 
during the period and adjusting net income for any changes in income or loss that would result from the conversion of such potential 
ordinary shares.

There is no difference in net income used for basic and diluted net income per ordinary share. The reconciliation of the number 
of shares used in the computation of basic and diluted net income per ordinary share is as follows:

Weighted average number of ordinary shares outstanding for basic net income 
per ordinary share
Effect of dilutive share options outstanding
Weighted average number of ordinary shares outstanding for diluted net income 
per ordinary share

(w)   Share-based compensation

The Company accounts for its share options, restricted share units ("RSUs") and performance share units ("PSUs") in accordance 
with the provisions of FASB ASC 718, Compensation – Stock Compensation. Share-based compensation expense for equity-

91

 
 
settled awards made to employees and Directors is measured and recognized based on estimated grant date fair values. These 
equity-settled awards include employee share options, RSUs and PSUs.

Share-based compensation expense for share options awarded to employees and Directors is estimated at the grant date based on 
each option's fair value as calculated using the Black-Scholes option-pricing model. Share-based compensation for RSUs and 
PSUs awarded to employees and Directors is calculated based on the market value of the Company's shares on the date of award 
of the RSUs and PSUs. The value of awards expected to vest is recognized as an expense over the requisite service periods. 
Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs materially from original 
estimates.

Estimating the grant date fair value of share options as of the grant date using an option-pricing model, such as the Black-Scholes 
model, is affected by the Company's share price as well as assumptions regarding a number of complex variables. These variables 
include, but are not limited to, the expected share price volatility over the term of the awards, risk-free interest rates and the 
expected term of the awards.

Liability classified awards are measured at the fair value of the award on the grant date and remeasured at each reporting period 
at fair value until the award is settled.  

(x)   Impairment of long-lived assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of 
an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount 
of the asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, 
the impairment to be recognized is measured at the amount by which the carrying amount of the asset exceeds the fair value of 
the asset. Assets to be disposed of are reported at the lower of the carrying amount of the asset or fair value less selling costs.

(y)   Derivative financial instruments

We enter into transactions in the normal course of business using various financial instruments in order to hedge against exposure 
to fluctuating exchange and interest rates. We use derivative financial instruments to reduce exposure to fluctuations in interest 
rates. A derivative is a financial instrument or other contract whose value changes in response to some underlying variable, which 
has an initial net investment smaller than would be required for other instruments that have a similar response to the variable and 
that will be settled at a future date. We do not enter into derivative financial instruments for trading or speculative purposes. We 
did not hold any interest rate swap contracts or forward currency contracts at December 31, 2018 or December 31, 2017. 

We use derivative financial instruments to reduce exposure to fluctuations in foreign exchange rates. During the years-ended 
December 31, 2017 and December 31, 2018 we entered into forward currency contracts in respect of identified exposure arising 
from euro payments. All contracts expired during the year ended December 31, 2018.

Our accounting policies for derivative financial instruments are based on whether they meet the criteria for designation as cash 
flow or fair value hedges. A designated hedge of the exposure to variability in the future cash flows of an asset or a liability, or of 
a forecasted transaction, is referred to as a cash flow hedge. A designated hedge of the exposure to changes in fair value of an asset 
or a liability is referred to as a fair value hedge. The criterion for designating a derivative as a hedge includes the assessment of 
the  instrument's  effectiveness  in  risk  reduction,  matching  of  the  derivative  instrument  to  its  underlying  transaction  and  the 
probability that the underlying transaction will occur. For derivatives with cash flow hedge accounting designation, we report the 
gain or loss from the effective portion of the hedge as a component of Other Comprehensive Income and reclassify it into earnings 
in the same period or periods in which the hedged transaction affects earnings and within the same Statement of Operations line 
item as the impact of the hedged transaction. For derivatives with fair value hedge accounting designation, we recognize gains or 
losses from the change in fair value of these derivatives, as well as the offsetting change in the fair value of the underlying hedged 
item, in earnings. Fair value gains and losses arising on derivative financial instruments not qualifying for hedge accounting are 
reported in our Consolidated Statement of Operations.

(z)   Financing costs and gain on interest rate hedge

The interest rate in respect of the Senior Notes is fixed at 3.64% for the five year term of the agreement. The associated interest 
cost is recognized in interest expense in the period since drawdown in December 2015.

Cash proceeds ($4.6 million) received in November 2015 in respect of the realized hedge gain are amortized to the Consolidated 
Statement of Operations, net against interest payable, over the period of the Senior Notes.

92

Deferred financing costs (including issue costs relating to the Senior Notes) are reported at cost less accumulated amortization 
and the related amortization expense is included in interest expense, in our Consolidated Statement of Operations.

(aa)   Reclassifications

Certain amounts in the consolidated financial statements have been reclassified where necessary to conform to the current year 
presentation.

The Company classifies its investment in short term investments as available for sale. Short term investments comprise highly 
liquid investments with maturities of greater than three months and minimum "A-" rated fixed and floating rate securities. Short 
term investments at December 31, 2018 have an average maturity of 1.22 years compared to 1.58 years at December 31, 2017. 
The investments are reported at fair value with unrealized gains or losses reported in a separate component of shareholders' equity. 
Any differences between the cost and fair value of investments are represented by accrued interest and unrealized gains/losses. 
The fair value of short term investments are represented by level 1 fair value measurements – quoted prices in active markets for 
identical assets.

The contractual maturity of certain investments in the portfolio is greater than 12 months; however, classification as short-term 
investments reflects the Company practice and intention in respect of these investments. The company recognizes the unrealized 
losses in fair value in equity as these unrealized losses on short term investments have been considered as temporary.

(b) 

Investments in equity - long term

The Company entered into subscription agreements with a number of funds. Capital totaling $6.2 million had been advanced under 
the terms of the subscription agreements at December 31, 2018.  The Company determined that the interests in the funds meet the 
definition of equity securities without readily determinable fair values. Effective from 1 January 2018, the Company concluded 
that the interests held at December 31, 2018 qualify for the NAV practical expedient in ASC 820 'Fair value measurements and 
disclosures'.  An increase in fair value of $0.8 million was recognized in net income during the period bringing the carrying value

of the subscriptions to $6.963  million at December 31, 2018. The Company had committed to future investments of $21.3 million

The Company has made a number of strategic acquisitions since inception to enhance its capabilities and experience in certain 
areas of the clinical development process. Goodwill arising on acquisition represents the excess of the cost of acquired entities 
over the net amounts assigned to assets acquired and liabilities assumed. Goodwill primarily comprises of the acquired workforce 
in place which does not qualify for recognition as an asset apart from goodwill.

The Company acquired Mapi Développement SAS ('Mapi') during the year-ended December 31, 2017 resulting in the recognition 
of goodwill of $130.3 million (note 4 (a)).

The Company tests goodwill annually for impairment or whenever events occur which may indicate impairment. The results of 
the Company's goodwill impairment testing assessed at September 30, 2018 during the year ended December 31, 2018 provided 
no evidence of impairment and indicated the existence of sufficient headroom such that a reasonably possible change to the key 
assumptions used would be unlikely to result in an impairment of the related goodwill.

(a) Acquisitions - Mapi Group

On July 27, 2017, a subsidiary of the Company, ICON Clinical Research Limited, acquired Mapi Group. Mapi Group is a leading 
patient-centered health outcomes research and commercialization company. Cash outflows on acquisition were $145.8 million. 
The acquisition agreement provided for working capital targets to be achieved. On March 26, 2018, the Company paid  $1.6 million 
in respect of these targets on completion of the working capital review. 

94

 
 
The  acquisition  of  Mapi  has  been  accounted  for  as  a  business  combination  in  accordance  with  FASB ASC  805  Business 
Combinations. The table following summarizes the Company’s assessment of the fair values of the assets acquired and liabilities

*Goodwill represents the acquisition of an established workforce with experience in late phase commercialization, analytics, real
world evidence generation and strategic regulatory services in clinical trial services for biologics, drugs and devices. Goodwill
related to the business acquired is not tax deductible. In finalizing the goodwill on acquisition of Mapi in the twelve month period
from acquisition, fair value adjustments were made which resulted in increases in other liabilities ($3.9 million), plant and equipment
($1.7 million) and accounts receivable ($1.7 million) and income taxes receivable ($1.5 million) and decreases in unbilled revenue
($4.8 million), prepayments and other current assets ($1.9 million) and other receivables ($1.0 million) and in payment on account
($2.6 million)  and non-current deferred tax liability ($9.1 million). Customer list and order backlog assets were also finalized.

The proforma effect of the Mapi acquisition if completed on January 1, 2016 would have resulted in net revenue, net income and 
earnings per share for the fiscal years ending December 31, 2017 and December 31, 2016 as follows:

(b) Acquisition of ICON Government & Public Health Solutions (formerly Clinical Research Management (ClinicalRM))

On September 15, 2016, a subsidiary of the Company, ICON US Holdings Inc. acquired ICON Government & Public Health 
Solutions (''GPHS'') (formerly Clinical Research Management (ClinicalRM)) which resulted in net cash outflows of $52.4 million
(including certain payments made on behalf of GPHS totaling $9.2 million). GPHS is a full-service CRO specializing in preclinical 
through Phase IV support of clinical research and clinical trial services for biologics, drugs and devices. The organization helps 

95

customers progress their products to market faster with a wide array of research, regulatory and sponsor services within the U.S.

Their extensive expertise extends across basic and applied research, infectious diseases, vaccines development, testing and the 
response to bio-threats. They have worked in collaboration with government and commercial customers to respond to the threat 
of global viral epidemics. Further consideration of up to $12.0 million was payable if certain performance milestones are achieved 
in respect of periods up to December 31, 2017. The fair value of the contingent consideration on acquisition and at March 31, 
2017, was estimated at $6.0 million. The evaluation of the performance and forecast performance of GPHS against performance 
milestones was updated as required at June 30, 2017. Arising from that evaluation, the fair value of the contingent consideration 
liability was determined as $Nil, resulting in a net credit of $6.0 million being recorded within selling, general & administrative 
expenses in the Consolidated Statement of Operations during the year ended December 31, 2017. 

The  acquisition  of  GPHS  has  been  accounted  for  as  a  business  combination  in  accordance  with  FASB ASC  805  Business 
Combinations. The table following summarizes the fair values of the assets acquired and liabilities assumed:

Certain Company employees are eligible to participate in a defined contribution plan (the "Plan"). Participants in the Plan may 
elect to defer a portion of their pre-tax earnings into a pension plan, which is run by an independent party. The Company 
matches participant's contributions typically at 8% of the participant's annual compensation. Contributions to the plan are 
recorded as an expense in the selling, general and administrative line in the Consolidated Statement of Operations. 
Contributions for the years ended December 31, 2018, December 31, 2017 and December 31, 2016 were $25,241,000, 
$20,355,000 and $20,952,000 respectively.

The Company's United States operations maintain a retirement plan (the "U.S. Plan") that qualifies as a deferred salary arrangement 
under Section 401(k) of the Internal Revenue Code. Participants in the U.S. Plan may elect to defer a portion of their pre-tax 
earnings, up to the Internal Revenue Service annual contribution limit. The Company matches participant's contributions up to 
3% and matches 50% of participant's contributions thereafter to a maximum Company contribution of 4.5% of the participant's 
annual compensation. Contributions to this U.S. Plan are recorded, in the year contributed, as an expense in the Consolidated 
Statement of Operations. Contributions for the years ended December 31, 2018, December 31, 2017 and December 31, 2016 were 
$15,532,000, $14,946,000 and $15,223,000 respectively.

The discount rate is determined by reference to UK long dated government and corporate bond yields at the Balance Sheet date. 
This is represented by the iboxx corporate bond over 15 year index plus 10 basis points.

Plan Assets

The assets of the scheme are invested with Legal and General and are held in a combination of: the Active Corporate Bond over 
10 Year fund, Gilt and Index Linked Gilt funds. The overall investment strategy is that approximately 75% of investments are in 
government bonds (both fixed interest and index linked), approximately 25% of investments are held in corporate bonds. There 
is no self-investment in employer related assets. The expected long-term rate of return on assets at December 31, 2018 of 2.1%
was calculated as the value of the fund after application of a market value reduction factor. The expected long term rates of return 
on different asset classes are as follows:

Asset Category

Corporate Bonds
Gilts
Cash

Expected long-
term return per
annum
2.9%
1.8%
2.9%

The long-term expected return on corporate bonds and gilts (fixed interest and index linked) is determined by reference to bond 
yields and gilt yields at the Balance Sheet date.

Applying the above expected long term rates of return to the asset distribution at December 31, 2018, gives rise to an expected 
overall rate of return of scheme assets of approximately 2.1% per annum.

The expected cash flows are estimated figures based on the members expected to retire over the next 10 years assuming no early 
retirements plus an additional amount based on recent average withdrawal experience. At the present time it is not clear whether 
annuities will be purchased when members reach retirement or whether pensions will be paid each month out of scheme assets. 
The cash flows above have been estimated on the assumption that pensions will be paid monthly out of scheme assets. If annuities 
are purchased, then the expected benefit payments will be significantly different from those shown above.

The discount rate is determined by reference to Swiss corporate bond yields at the Balance Sheet date.

Plan Assets

The pension plan is an insured arrangement with Swiss Life. The assets are an insurance contract whose value depends on the 
amount saved by employees and the interest granted by Swiss Life. The value of assets does not depend on the performance of 
any underlying assets. There is no self-investment in employer related assets. 

Cash Flows

The Company expects to contribute $0.1 million to its pension fund in the year ending December 31, 2019.

The following annual benefit payments, which reflect expected future service as appropriate, are expected to be paid.

The expected cash flows are estimated figures based on the members expected to retire over the next 10 years assuming no early 
retirements plus an additional amount based on recent average withdrawal experience. At the present time it is not clear whether 
annuities will be purchased when members reach retirement or whether pensions will be paid each month out of scheme assets. 
The cash flows above have been estimated on the assumption that pensions will be paid monthly out of scheme assets. If annuities 
are purchased, then the expected benefit payments will be significantly different from those shown above.

10. Equity Incentive Schemes and Stock Compensation Charges

Share Options

On July 21, 2008 the Company adopted the Employee Share Option Plan 2008 (the "2008 Employee Plan") pursuant to which the 
Compensation and Organization Committee of the Company's Board of Directors may grant options to any employee, or any 
Director holding a salaried office or employment with the Company or a Subsidiary for the purchase of ordinary shares. On the 
same date, the Company also adopted the Consultants Share Option Plan 2008 (the "2008 Consultants Plan"), pursuant to which 
the Compensation and Organization Committee of the Company's Board of Directors may grant options to any consultant, adviser 
or non-executive Director retained by the Company or any Subsidiary for the purchase of ordinary shares.

On February 14, 2017 both the 2008 Employee Plan and the 2008 Consultants Plan (together the "2008 Option Plans") were 
amended and restated in order to increase the number of options that can be issued under the 2008 Consultants Plan from 400,000
to 1 million and to extend the date for options to be granted under the 2008 Option Plans.

An aggregate of 6.0 million ordinary shares have been reserved under the 2008 Employee Plan, as reduced by any shares issued 
or to be issued pursuant to options granted under the 2008 Consultants Plan, under which a limit of 1 million shares applies. 

106

 
 
 
 
Further, the maximum number of ordinary shares with respect to which options may be granted under the 2008 Employee Option 
Plan, during any calendar year to any employee shall be 400,000 ordinary shares. There is no individual limit under the 2008 
Consultants Plan. No options may be granted under the 2008 Option Plans after February 14, 2027.

Each option granted under the 2008 Option Plans will be an employee stock option, or NSO, as described in Section 422 or 423 
of the Internal Revenue Code. Each grant of an option under the 2008 Options Plans will be evidenced by a Stock Option Agreement 
between the optionee and the Company. The exercise price will be specified in each Stock Option Agreement, however option 
prices will not be less than 100% of the fair market value of an ordinary share on the date the option is granted.

On January 17, 2003 the Company adopted the Share Option Plan 2003 (the "2003 Share Option Plan") pursuant to which the 
Compensation and Organization Committee of the Board could grant options to officers and other employees of the Company or 
its subsidiaries for the purchase of ordinary shares. An aggregate of 6.0 million ordinary shares were reserved under the 2003 
Share Option Plan; and in no event could the number of ordinary shares issued pursuant to options awarded under this plan exceed 
10% of the outstanding shares, as defined in the 2003 Share Option Plan, at the time of the grant, unless the Board expressly 
determined otherwise. Further, the maximum number of ordinary shares with respect to which options could be granted under the 
2003 Share Option Plan during any calendar year to any employee was 400,000 ordinary shares. The 2003 Share Option Plan 
expired on January 17, 2013. No new options may be granted under this plan.

Share option awards are granted with an exercise price equal to the market price of the Company's shares at date of grant. Prior 
to 2018, share options typically vest over a period of five years from date of grant and expire eight years from date of grant. Share 
options granted to non-executive directors during 2018 vest over 12 months and expire eight years from the date of grant.  The 
maximum contractual term of options outstanding at December 31, 2018 is eight years.

The following table summarizes the transactions for the Company's share option plans for the years ended December 31, 2018,

year ended December 31, 2019 (255,198 options were expected to vest during the year ended December 31, 2018).

The intrinsic value of options exercised during the year ended December 31, 2018 amounted to $38.2 million. The intrinsic value 
of options outstanding and options exercisable at December 31, 2018 amounted to $48.6 million and $28.3 million respectively. 
Intrinsic value is calculated based on the market value versus strike price of the Company's shares at the date of exercise.

Fair value of Stock Options Assumptions

The  weighted  average  fair  value  of  options  granted  during  the  years  ended  December 31,  2018,  December 31,  2017  and 
December 31, 2016 was calculated using the Black-Scholes option pricing model. The weighted average fair values and assumptions 
were as follows:

Expected volatility is based on the historical volatility of our common stock over a period equal to the expected term of the options; 
the  expected  life  represents  the  weighted  average  period  of  time  that  options  granted  are  expected  to  be  outstanding  given 
consideration to vesting schedules and our historical experience of past vesting and termination patterns. The risk-free rate is based 
on the U.S. government zero-coupon bonds yield curve in effect at time of the grant for periods corresponding with the expected 
life of the option.

Restricted Share Units and Performance Share Units

On July 21, 2008 the Company adopted the 2008 Employees Restricted Share Unit Plan (the "2008 RSU Plan") pursuant to which 
the Compensation and Organization Committee of the Company's Board of Directors may select any employee, or any Director 
holding a salaried office or employment with the Company, or a Subsidiary to receive an award under the plan. An aggregate of 
1.0 million ordinary shares have been reserved for issuance under the 2008 RSU Plan.

On April 23, 2013 the Company adopted the 2013 Employees Restricted Share Unit and Performance Share Unit Plan (the "2013 
RSU Plan") pursuant to which the Compensation and Organization Committee of the Company's Board of Directors may select 
any employee, or any Director holding a salaried office or employment with the Company, or a Subsidiary to receive an award 
under the plan. On May 11, 2015 the 2013 RSU Plan was amended and restated in order to increase the number of shares that can 
be issued under the RSU Plan by 2.5 million shares. Accordingly, an aggregate of 4.1 million ordinary shares have been reserved 
for issuance under the 2013 RSU Plan. The shares are awarded at par value and vest over a service period. Awards under the 2013 
RSU Plan may be settled in cash or shares at the option of the Company.

The Company has awarded RSUs and PSUs to certain key individuals of the Group. The following table summarizes RSU and

2021. Since 2013, 147,630 PSUs (net of forfeitures) have been granted. Depending on the actual amount of EPS from 2015 to 
2021, up to an additional 103,423 PSUs may also be granted.

Non-cash stock compensation expense

Income from operations for the year ended December 31, 2018 is stated after charging $31.6 million in respect of non-cash stock 
compensation expense. Non-cash stock compensation expense has been allocated as follows:

Total non-cash stock compensation expense not yet recognized at December 31, 2018 amounted to $43.1 million. The weighted 
average period over which this is expected to be recognized is 2.19 years. 

The amendments required by Accounting Standards Update (‘ASU’) 2016-09 ‘Improvements to Employee Share-Based Payment 
Accounting’ require the Company to record all tax effects related to share-based payments through the income statement rather 
than additional paid in capital. The Company has applied the updated standard prospectively in the twelve months of the year 
ended December 31, 2017. 

The income tax expense for the year ended December 31, 2018 reflects a net income tax benefit of $12.7 million in connection 
with stock compensation (including excess tax benefits) and the total tax benefit in connection with stock options exercised during 
2018 was $3.6 million. The income tax expense for the year ended December 31, 2017 reflects a net income tax benefit of $9.3 
million in connection with stock compensation (including excess tax benefits) and the total tax benefit in connection with stock 
options exercised during 2017 was $3.2 million.  The income tax expense for the year ended December 31, 2016 reflects a net 
income tax benefit of $3.5 million in connection with stock compensation (excluding excess tax benefits) and the cash tax benefit 
realized in connection with stock options exercised during 2016 was $3.4 million.

Capital grants received may be refundable in full if certain events occur. Such events, as set out in the related grant agreements, 
include sale of the related asset, liquidation of the Company or failure to comply with other conditions of the grant agreements. 
No loss contingency has been recognized as the likelihood of such events arising has been assessed as remote. Government grants 
amortized to the profit and loss account amounted to $47,000 for the year ended December 31, 2018. A net charge of $44,000 was 
recorded in respect of government grants during the year ended December 31, 2017. As at December 31, 2018 the Company had 
$3.2 million in restricted retained earnings, pursuant to the terms of grant agreements.

12. Share Capital

Holders of ordinary shares will be entitled to receive such dividends as may be recommended by the Board of Directors of the 
Company and approved by the shareholders and/or such interim dividends as the Board of Directors of the Company may decide. 
On liquidation or a winding up of the Company, the par value of the ordinary shares will be repaid out of the assets available for 
distribution among the holders of the ordinary shares of the Company. Holders of ordinary shares have no conversion or redemption 
rights. On a show of hands, every holder of an ordinary share present in person or proxy at a general meeting of shareholders shall 
have one vote, for each ordinary share held with no individual having more than one vote. 

During the year ended December 31, 2018, 408,699 options were exercised by employees at an average exercise price of $41.12
per share for total proceeds of $16.8 million. During the year ended December 31, 2018, 276,495 ordinary shares were issued in 
respect of certain RSUs and 215,826 ordinary shares were issued in respect of PSUs previously awarded by the Company.

During the year ended December 31, 2017, 458,243 options were exercised by employees at an average exercise price of $30.35
per share for total proceeds of $13.9 million. During the year ended December 31, 2017, 361,102 ordinary shares were issued in 
respect of certain RSUs and 320,640 ordinary shares were issued in respect of PSUs previously awarded by the Company.

During the year ended December 31, 2016, 393,240 options were exercised by employees at an average exercise price of $25.79
per share for total proceeds of $10.1 million. During the year ended December 31, 2016, 296,386 ordinary shares were issued in 
respect of certain RSUs and 311,492 ordinary shares were issued in respect of PSUs previously awarded by the Company.

(a)  Share Repurchase Program

On October 3, 2016 the Company commenced a previously announced share buyback program of up to $400 million. During the 
year  ended  December 31,  2018,  the  Company  redeemed  a  total  of  1,008,162  ordinary  shares  under  this  program  for  total 
consideration of $129.0 million.  At December 31, 2018 a total of 4,026,576 ordinary shares were redeemed by the Company 
under this buyback program for a total consideration of $372.1 million. All ordinary shares that were redeemed under the buyback 
program were canceled in accordance with the Constitution of the Company and the nominal value of these shares transferred to 
a other undenominated capital fund as required under Irish Company Law.

On July 31, 2015 the Company commenced a buyback program of up to $400 million under which the Company could acquire 
its outstanding ordinary shares (by way of redemption), in accordance with Irish law, the United States securities laws and the 
Company's constitutional documents through open market share acquisitions. A total of 5,316,062 ordinary shares were redeemed 
by the Company under this buyback program for a total consideration of $400 million. All ordinary shares that were redeemed 
under the buyback program were canceled in accordance with the Constitution of the Company and the nominal value of these 
shares transferred to a other undenominated capital reserve as required under Irish Company Law. The share buyback program 
was completed in December 31, 2015, with a total of 6,198,481 ordinary shares redeemed during the year ended December 31, 
2015 for total consideration of $457.9 million (including the programe for $400 million).

Under the repurchase program, a broker purchased the Company's shares from time to time on the open market or in privately 
negotiated transactions in accordance with agreed terms and limitations. The program was designed to allow share repurchases 
during periods when the Company would ordinarily not be permitted to do so because it may be in possession of material non-
public  or  price-sensitive  information  or  due  to  applicable  insider  trading  laws  or  self-imposed  trading  blackout  periods. The 
Company's instructions to the broker were irrevocable and the trading decisions in respect of the repurchase program were made 
independently of and uninfluenced by the Company. The Company confirms that on entering the share repurchase plans it had no 
material non-public, price-sensitive or inside information regarding the Company or its securities. Furthermore, the Company will 
not enter into additional plans whilst in possession of such information. The timing and actual number of shares acquired by way 
of the redemption will be dependent on market conditions, legal and regulatory requirements and the other terms and limitations 
contained in the program. In addition, acquisitions under the program may be suspended or discontinued in certain circumstances 
in accordance with the agreed terms. Therefore, there can be no assurance as to the timing or number of shares that may be acquired 
under the program.

At December 31, 2018 Ireland subsidiaries had tax credit carry-forwards for income tax purposes that may be carried forward 
indefinitely, available for offset against future tax liabilities, if any, of $4.0 million (2017: $4.5 million).

At December 31, 2018 U.S. subsidiaries had U.S. federal and state net operating loss ("NOL") carry-forwards of approximately 
$15.1 million and $32.6 million, respectively. These NOLs are available for offset against future taxable income and expire between 
2022 and 2037. Of the $15.1 million U.S. federal NOLs, approximately $2.2 million is available for offset against future U.S. 
federal taxable income. The subsidiary's ability to use the  remaining U.S. federal and state NOL carry-forwards is limited on an 
annual basis due to changes of ownership in 2000, 2010, 2014 and 2017, as defined by Section 382 of the Internal Revenue Code 
of 1986, as amended. Of the U.S. federal NOLs, $12.9 million are limited by Section 382. Of the $12.9 million of losses, the 
amounts are available as follows: $4.9 million for the years 2019 – 2020, $7.5 million in 2021-2025, $0.5 million for the years 
2026 – 2035. As at December 31, 2018 , U.S subsidiaries also had excess disallowed interest carry-forwards of $21.9 million. 
These carry-forwards are available for offset against future taxable income in the event that the U.S subsidiaries have excess 
capacity for interest deductions in future years. 

At December 31, 2018 other than those in the U.S. and Ireland, we had operating loss carry-forwards for income tax purposes that 
may be carried forward indefinitely, available to offset against future taxable income, if any, of approximately $72.9 million (2017: 
$77.2 million). In addition at December 31, 2018 those subsidiaries had tax credit carry-forwards for income tax purposes that 
may be carried forward indefinitely, available to offset against future tax liabilities, if any, of $4.9 million (2017: $4.8 million). 
At December 31, 2018 those subsidiaries also had additional operating loss carry forwards of $4.7 million which are due to expire 
between 2019 and 2025 (2017: $4.7 million) and operating carry-forwards of $3.2 million which are due to expire between 2026 
and 2035 (2017: $0 million).

In addition, US subsidiaries have alternative minimum tax credit carry-forwards of approximately $0.4 million that are available 
to reduce future U.S. federal regular income taxes through 2020. Any remaining alternative minimum tax credits will be fully 
refundable in 2021. We also have minimum tax credit carry-forwards of approximately $0.3 million that are available to offset 
future U.S. federal income taxes. These credits will be fully used or refunded before 2022.

The valuation allowance at December 31, 2018 was approximately $27.3 million. The valuation allowance for deferred tax assets 
as of December 31, 2017 and December 31, 2016 was $22.4 million and $20.3 million respectively. The net change in the total 
valuation allowance was an increase of $4.8 million during 2018 and an increase of $2.1 million during 2017. Of the total increase 
of  $4.8  million  in  2018,  $5.6  million  resulted  in  current  year  income  tax  expense  and  $0.8  million  was  recognized  in  Other 
Comprehensive Income. Of the total increase of $2.1 million in 2017, $0.5 million resulted in a current year income tax expense,   
and $1.6 million was recognized in Other Comprehensive Income.

The valuation allowances at December 31, 2018 and December 31, 2017 were primarily related to operating losses and tax credits 
carried forward that, in the judgment of management, are not more likely than not to be realized. In assessing the realizability of 
deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will 
not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during 
the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred 
tax liabilities and projected future taxable income in making this assessment. In respect of deferred tax assets not subject to a 
valuation allowance, management considers that it is more likely than not that these deferred tax assets will be realized on the 
basis that there will be sufficient reversals of deferred tax liabilities and taxable income in future periods. During 2017, there were 
no movements in the valuation allowance that had a material impact on the effective tax rate. During 2018, the Company recognized 
a valuation allowance of $6.2 million in respect of disallowed interest carry-forwards generated during the year as management 
does not consider it more likely than not that the Company will have sufficient capacity with which to utilize these losses.

The Company has recognized a deferred tax liability of $4.9 million (2017: $3.1 million) for investments in foreign subsidiaries 
where the Company does not consider the earnings to be indefinitely reinvested.  For the deferred tax liability not recognized in 
respect of temporary differences related to investments in foreign subsidiaries which are consider to be indefinitely reinvested, it 
is not practicable to calculate the exact unrecognized deferred tax liability, however it is not expected to be material as Ireland 
allows a tax credit in respect of distributions from foreign subsidiaries at the statutory tax rate in the jurisdiction of the subsidiary 
so that no material tax liability would be expected to arise in the event these earnings were ever remitted. In addition, withholding 
taxes applicable to remittances from foreign subsidiaries would not be expected to be material given Ireland’s tax treaty network 
and the EU parent subsidiary directive.

A reconciliation of the beginning and ending amount of total unrecognized tax benefits is as follows:

The relevant statute of limitations for unrecognized tax benefits totaling $1.3 million could potentially expire during 2019. 

Included in the balance of total unrecognized tax benefits at December 31, 2018 were potential benefits of $21.4 million, which 
if recognized, would affect the effective rate on income tax from continuing operations. The balance of total unrecognized tax 
benefits at December 31, 2017 and December 31, 2016 included potential benefits which, if recognized, would affect the effective 
rate of income tax from continuing operations of $23.7 million and $26.6 million respectively.

Interest and penalties recognized as a net benefit during the year ended December 31, 2018 amounted to $1.3 million (2017: net 
expense of $0.9 million, 2016: net expense of $0.1 million) and are included within the provision for income taxes. Total accrued 
interest and penalties as of December 31, 2018 and December 31, 2017 were $1.1 million and $2.4 million respectively and are 
included in closing income taxes payable at those dates.

Our major tax jurisdictions are the United States and Ireland. We may potentially be subjected to tax audits in both our major 
jurisdictions. In the United States tax periods open to audit include the years ended December 31, 2015, December 31, 2016, 
December 31, 2017 and December 31, 2018. In Ireland, tax periods open to audit include the years ended December 31, 2014,

Timing may differ between the satisfaction of performance obligations and the invoicing and collection of amounts related to our 
contracts with customers. We record assets for amounts related to performance obligations that are satisfied but not yet billed and/
or collected. These assets are recorded as unbilled receivables and therefore contract assets rather than accounts receivables when 
receipt of the consideration is conditional on something other than the passage of time. Liabilities are recorded for amounts that 
are collected in advance of the satisfaction of performance obligations.

Unbilled services/revenue balances arise where invoicing or billing is based on the timing of agreed milestones related to service 
contracts  for  clinical  research.  Contractual  billing  arrangements  in  respect  of  certain  reimbursable  expenses  (principally 
investigators) require billing by the investigator to the Company prior to billing by the Company to the customer.    

The most significant impact of application of ASC 606 is the measurement of a clinical trial service as a single performance 
obligation recognized over time. We concluded that ICON is the contract principal in respect of both direct services and in the use 
of third parties (principally investigator services) that support a clinical trial. The progress towards completion for clinical service 
contracts is measured based on total project costs (including reimbursable costs). Reimbursable expenses are included within 
direct costs on adoption of ASC 606 and are recorded based on activity undertaken by the third party.  Amounts owed to investigators 
and others in respect of reimbursable expenses at December 31, 2018 were $85.6 million (see note 7 Other liabilities).  

Payments on account decreased by $24.5 million over the same period resulting in an increase of $118.9 million in the net balance 
of unbilled services and payments on account between December 31, 2017 and December 31, 2018. These fluctuations are primarily 
due to timing of payments and invoicing related to the Group's clinical trial management contracts. Billings and payments are 
established by contractual provisions including predetermined payment schedules which may or may not correspond to the timing 
of the transfer of control of the Company's services under the contract.  Unbilled services arise from long-term contract when a 
cost-based input method of revenue recognition is applied and revenue recognized exceeds the amount billed to the customer. 

The bad debt expense recognized on the Group's receivables and unbilled services was $0.7 million for the twelve months ended 
December 31, 2018.

As of December 31, 2018 approximately $5.3 billion of revenue is expected to be recognized in the future in respect of unsatisfied 
performance  obligations.  The  Company  expects  to  recognize  revenue  on  approximately  40%  of  the  unrealized  performance 
obligation over the next 12 months, with the remainder recognized thereafter over the duration of the customer contracts.

19. Business Segment and Geographical Information

The Company is a clinical research organization ("CRO"), providing outsourced development services on a global basis to the 
pharmaceutical, biotechnology and medical device industries. It specializes in the strategic development, management and analysis 
of programs that support all stages of the clinical development process - from compound selection to Phase I-IV clinical studies. 
The Company has the expertise and capability to conduct clinical trials in most major therapeutic areas on a global basis and has 
the operational flexibility to provide development services on a stand-alone basis or as part of an integrated "full service" solution. 
The Company has expanded predominately through internal growth, together with a number of strategic acquisitions to enhance 
its expertise and capabilities in certain areas of the clinical development process.

The Company determines and presents operating segments based on the information that is internally provided to the chief operating 
decision maker, together the ('CODM') in accordance with FASB ASC 280-10 Disclosure about Segments of an Enterprise and 
Related Information.  The Chief Executive Officer, Chief Financial Officer and Chief Operating Officer, were together considered 
the Company's CODM in the period up to and including March 1, 2017. On March 1, 2017, Mr Ciaran Murray transitioned from 
his role as Chief Executive Officer to the role of Executive Chairman of the Board of Directors and Dr. Steve Cutler was appointed 
as Chief Executive Officer.  As of March 1, 2017, the Company determined that the CODM was comprised of the Chief Executive 
Officer and the Chief Financial Officer in accordance with the requirements of  ASC 280-10 Disclosures about Segments of an 
Enterprises and Related Information.

The Company operates as one business segment, which is the provision of outsourced development services on a global basis to 
the pharmaceutical, biotechnology and medical devices industries.

Revenues are allocated to individual entities based on where the work is performed in accordance with the Company's global 
transfer pricing model. Revenues and income from operations in Ireland are a function of this transfer pricing model.

Given ICON Clinical Research Limited's ("ICON Ireland") role in the development and management of the Group, it's ownership 
of key intellectual property, customer relationships, its key role in the mitigation of risks faced by the Group, plus the responsibility 
for maintaining the Group's global network, ICON Ireland acts as the group entrepreneur and enters into the majority of the 
Company's  customer  contracts. As  such,  ICON  Ireland  remunerates  most  of  the  other  operating  entities  ("cost  plus  service 
providers") in the ICON Group on the basis of a guaranteed cost plus mark up for the services they perform in each of their local 
territories.

The cost plus mark up for each ICON entity is established to ensure that each of ICON Ireland and the ICON entities in the various 
geographical areas that are involved in the conduct of services for customers, earn an appropriate arms-length return having regard 
to the assets owned, risks borne and functions performed by each entity from these intercompany transactions. The cost plus mark-
up policy is reviewed annually to ensure that it is market appropriate.

Under this method, the residual operating profits (or losses) of the Group, once the cost plus service providers have been paid 
their respective intercompany service fee, are retained by ICON Ireland. The geographic split of revenue disclosed for each region 
outside Ireland is the cost plus revenue attributable to these entities. The revenues disclosed as relating to Ireland are the net 
revenues after deducting the cost plus revenues attributable to the activities performed outside Ireland.

119

 
 
 
The Company's areas of operation outside of Ireland include the United States, United Kingdom, Belgium, France, Germany, Italy, 
Spain, The Netherlands, Sweden, Turkey, Poland, Czech Republic, Latvia, Russia, Ukraine, Hungary, Israel, Romania, Canada, 
Mexico, Brazil, Colombia, Argentina, Chile, Peru, India, China (including Hong Kong), South Korea, Japan, Thailand, Taiwan, 
Singapore, The Philippines, Australia, New Zealand, and South Africa.

There have been no changes to the basis of segmentation or the measurement basis for the segment results since the prior year.

Reportable segment information at December 31, 2018 and December 31, 2017 and for the years ended December 31, 2018,

In December 2015 the Company issued $350 million in the private placement market which is due for repayment in 2020. 

The interest rate in respect of the Senior Notes is fixed at 3.64% for the five year term of the agreement. The associated interest 
cost is recognized in interest expense in the period since drawdown in December 2015.

In October 2015, the Company entered into an interest rate hedge in respect of the planned issuance of the Senior Notes in December 
2015. The interest rate hedge matured in November 2015 when the interest rate on the Senior Notes was fixed. The interest rate 
hedge was effective in accordance with Financial Accounting Standards Board ("FASB") ASC 815, "Derivatives and Hedging". 
The cash proceeds ($4.6 million), representing the realized gain on the interest rate hedge, were received on maturity in November 
2015 and are recorded within Other Comprehensive Income. The realized gain is being amortized to the income statement, net 
against interest payable, over the period of the Senior Notes.

The Senior Notes agreement also includes certain financial covenants that require compliance with a consolidated leverage ratio, 
a minimum EBIT to consolidated net interest charge ratio and a maximum amount of priority debt, each of which are defined in 
the Note Purchase and Guarantee Agreement. The Company was in compliance with these covenants at December 31, 2018.  

The Senior Notes have not been, and will not be, registered under the Securities Act of 1933, as amended, and may not be offered 
or sold in the United States absent registration or an applicable exemption from registration requirements.

23. Impact of New Accounting Pronouncements

Impact of new accounting pronouncements adopted during fiscal year-ended December 31, 2018

ASC 606 'Revenue from Contracts with Customers'
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which provides that an 
entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the 
consideration to which the entity expects to be entitled in exchange for those goods or services. The updated standard replaces 
most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective 
or cumulative effect transition method. To achieve the core principle of the new standard, an entity should apply the following 
steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the 
transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when 
(or as) the entity satisfies a performance obligation. Subsequent to issuing ASU 2014-09, the FASB issued the following amendments 
concerning clarification of ASU 2014-09. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers 
(Topic 606), Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08”), which further clarifies 
the implementation guidance on principal versus agent considerations. The new guidance requires either a retrospective or a 
modified retrospective approach to adoption. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers 
(Topic  606),  Identifying  Performance  Obligations  and  Licensing  (“ASU  2016-10”),  which  clarifies  the  identification  of 
performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. In May 

123

 
 
2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and 
Practical Expedients (“ASU 2016-12”), which provides clarification on assessing the collectability criterion, presentation of sales 
taxes, measurement date for non-cash consideration and completed contracts at transition. 

The updated standard was effective for ICON in the first quarter of the year ended December 31, 2018. ICON elected to adopt 
the updated standard using the cumulative effect transition method. Under this transition method, ICON applied the new standard 
as of the date of initial application (i.e. January 1, 2018), without restatement of comparative period amounts. ICON  recorded 
the cumulative effect of initially applying the new standard (to revenue and cost) as an adjustment to the opening balance of equity 
at  the  date  of  initial  application. The  most  significant  impact  relates  to  our  assessment  of  measurement  of  performance  and 
percentage of completion in respect of our clinical trials service revenue. ICON applied the requirements of the new standard to 
those contracts not completed at the date of initial application. See note 26 Impact of New Accounting Policy for the impact of the 
adoption of the new accounting standard.  

In May 2017, the FASB issued ASU 2017-10 'Service Concession Arrangements (Topic 853): Determining the Customer of the 
Operation Services' which clarifies that the customer in a service concession arrangement is always the grantor. This ASU is 
effective at the same time as ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (the new revenue standard). 

• 

• 

If an entity had early adopted the new revenue standard before this ASU was issued (May 16, 2017), the entity may adopt 
this ASU on its effective date with certain specific transition provisions.
If an entity early adopts the new revenue standard after this ASU was issued, the entity must adopt this ASU at the same 
time as the new revenue standard with certain specific transition provisions. 

•  An entity may elect to early adopt this ASU before the adoption of the new revenue standard with certain specific transition 

provisions.

The adoption of the ASU did not have a significant impact on the financial statements. 

In January 2017, the FASB issued ASU 2017-01 'Business combinations - Clarifying the definition of a business' to provide a new 
framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses.  
This ASU was effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 
2017.  The ASU may be early adopted. The adoption of ASU 2017-01 did not have a significant impact on the financial statements.  

In March 2017, the FASB issued ASU 2017-07 'Compensation-Retirement Benefits (Topic 715): Improving the Presentation of 
Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost' which requires companies to present the service cost 
component of net benefit cost in the same line items in which they report compensation cost. Companies will present all other 
components of net benefit cost outside operating income, if this subtotal is presented. This ASU was effective for public business 
entities for annual and interim periods in fiscal years beginning after December 15, 2017. The adoption of ASU 2017-07 did not 
have a significant impact on the financial statements.  

In January 2016, the FASB issued ASU 2016-01 'Financial Instruments- Overall (Subtopic 825-10): Recognition and Measurement 
of the Financial Assets and Financial Liabilities' which will significantly change the income statement impact of equity investments 
and the recognition of changes in fair value of financial liabilities when the fair value option is elected. The ASU was effective 
for public business entities for interim and annual periods in fiscal years beginning after December 15, 2017. The adoption of 
ASU 2016-01did not have a significant impact on the financial statements.

In March 2016, the FASB issued ASU 2016-04, 'Recognition of Breakage for Certain Prepaid Stored-Value Products', which 
allows entities to recognize breakage on prepaid stored-value products consistent with how breakage is recognized under the new 
revenue standard. The exception applies to prepaid stored-value products in physical or digital form, with stored monetary values 
that are redeemable for goods and services, including those that can be redeemed for cash (e.g. prepaid gift cards issued on a 
specific  payment  network  and  redeemable  at  network-accepting  merchant  locations,  prepaid  telecommunication  cards,  and 
traveler's checks). The ASU was effective for public business entities for interim and annual periods in fiscal years beginning after 
December 15, 2017. The adoption of ASU 2016-04 did not have a significant impact on the financial statements.

In August 2016, the FASB issued ASU 2016-15, 'Classification of Certain Cash Receipts and Cash Payments', which addresses 
eight classification issues related to the statement of cash flows:

•  Debt prepayment or debt extinguishment costs;

• 

Settlement of zero-coupon bonds;

•  Contingent consideration payments made after a business combination;

• 

Proceeds from the settlement of insurance claims;

124

• 

Proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies;

•  Distributions received from equity method investees;

•  Beneficial interests in securitization transactions; and

• 

Separately identifiable cash flows and application of the predominance principle.

The ASU was effective for public business entities for interim and annual periods in fiscal years beginning after December 15, 
2017. The adoption of ASU 2016-15 did not have a significant impact on the financial statements.  Any contingent consideration 
payment arrangements arising on business combinations effected in the future will be reviewed for cash flow statement classification 
in line with ASU 2016-15. There were no contingent consideration payment arrangements during the year ended December 31, 
2018. 

In October 2016, the FASB issued ASU 2016-16, 'Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory',
which requires entities to recognize at the transaction date the income tax consequences of intercompany asset transfers other than 
inventory. This ASU  was  effective  for  public  business  entities  for  annual  and  interim  periods  in  fiscal  years  beginning  after 
December 15, 2017. For all other entities, the ASU is effective for annual periods in fiscal years beginning after December 15, 
2018,  and  interim  periods  in  fiscal  years  beginning  after  December  15,  2019. The  adoption  of ASU  2016-16  did  not  have  a 
significant impact on the financial statements.

In November 2016, the FASB issued ASU 2016-18, 'Statement of Cash Flows (Topic 230): Restricted Cash', which requires 
companies to include cash and cash equivalents that have restrictions on withdrawal or use in total cash and cash equivalents on 
the statement of cash flows. This ASU was effective for public business entities for annual and interim periods in fiscal years 
beginning after December 15, 2017. For all other entities, the ASU is effective for annual periods in fiscal years beginning after 
December 15, 2018, and interim periods in fiscal years beginning after December 15, 2019. The adoption of ASU 2016-18 did 
not have a material impact on the financial statements.

Financial statement effects of tax reform

H.R.1 was enacted on December 22, 2017.  The effective date of the law for most provisions is January 1, 2018 however the effects 
were required to be recognized in December 2017 financial statements.  In response, the SEC staff issued SAB 118, which allows 
registrants to record provisional amounts during a 'measurement period'. See Note 13 for assessment of impact of H.R.1 on the 
December 31, 2017 financial statements.    

Impact of new accounting pronouncements which will be adopted during fiscal year-ended December 31, 2019 

In February 2016, the FASB issued ASU 2016-02, 'Leases', requiring lessees to recognize a right-of-use asset and a lease liability 
on the Consolidated Balance Sheet for all leases with the exception of short-term leases. For lessees, leases will continue to be 
classified as either operating or finance leases in the income statement. Lessor accounting is similar to the current model but 
updated to align with certain changes to the lessee model. Lessors will continue to classify leases as operating, direct financing 
or sales-type leases. The effective date of the new standard for public companies is for fiscal years beginning after December 15, 
2018 and interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted using a modified 
retrospective transition and requires application of the new guidance at the beginning of the earliest comparative period presented. 
The updated standard is effective for us beginning in the first quarter of the year-ended December 31, 2019. We are currently 
evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures. See Note 
15 Commitments and Contingencies for details of operating leases held during year-ended December 31, 2018. A lease liability 
and right-of-use asset will be recorded on the Consolidated Balance Sheet at December 31, 2019. We estimate the impact of the 
adoption of ASC 842 will be the recognition of a right-of use asset and of lease liabilities in the range of $100 million to $110 
million. Under the new standard we expect an insignificant change in net result due to the replacement of operating leases expenses 
with amortization of the lease asset and the interest expense.

In July 2018, the FASB issued ASU 2018-11, which creates a new, optional transition method for implementing ASU 2016-02 
and a lessor practical expedient for separating lease and non-lease components.
This ASU is effective:
For entities that have not early adopted ASU 2016-02, with the effective date of ASU 2016-02.
• 
• 
For entities that have early adopted ASU 2016-02, upon issuance. However, it can only be adopted by entities either at 
(1) the beginning of the company’s first reporting period after issuance or (2) the entity’s mandatory ASC 842 effective date.  The 
Company has elected to adopt this transition method for implementing ASU 2016-02 and the related practical expedient.    

125

In July 2018, the FASB issued ASU 2018-10, which clarifies and corrects errors in ASC 842. The effective date and transition 
requirements in ASU 2018-10 are the same as the effective date and transition requirements of ASU 2016-02.

In January 2018, the FASB issued ASU 2018-01, which clarifies that land easements are in the scope of ASU 2016-02, Leases, 
and provides transition relief. The effective date and transition requirements in ASU 2018-01 are the same as the effective date 
and transition requirements of ASU 2016-02. 

In August 2017, the FASB issued ASU 2017-12 'Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for 
Hedging Activities' which changes the recognition and presentation requirements of hedge accounting, including:

•  Eliminating the requirement to separately measure and report hedge ineffectiveness; and
• 

Presenting all items that affect earnings in the same income statement line item as the hedged item.

The ASU also provides new alternatives for:

•  Applying hedge accounting to additional hedging strategies;
•  Measuring the hedged item in fair value hedges of interest rate risk;
•  Reducing the cost and complexity of applying hedge accounting by easing the requirements for effectiveness testing, 

hedge documentation and application of the critical terms match method; and

•  Reducing the risk of material error correction if a company applies the shortcut method inappropriately.

This ASU is effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 
2018. Early adoption is permitted any time after the issuance of the ASU, including in an interim period. If adopted at other than 
the beginning of a fiscal year, cumulative effect adjustments are reflected as of the beginning of the fiscal year. The adoption of 
the ASU is not expected to have a significant impact on the financial statements.  

In February 2017, the FASB issued ASU 2017-05 'Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets 
(Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets'.  
In February 2017, the FASB issued ASU 2017-05, which clarifies the guidance in Subtopic 610-20 on accounting for derecognition 
of a nonfinancial asset. The ASU also defines in-substance nonfinancial assets and includes guidance on partial sales of non-
financial assets. The adoption of ASU 2017-05 is not expected to have an impact on the financial statements. 

In July 2017, the FASB issued ASU 2017-11 'Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); 
Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part 
II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and 
Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception' under which down round features will not 
cause certain equity-linked financial instruments to be accounted for as derivatives. A company that presents EPS information 
will reflect the effect of a down round feature of free-standing equity-linked financial instruments in EPS only if it is triggered. 
The ASU is effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2018.   
The adoption of the ASU is not expected to have an impact on the financial statements.

In June 2016, the FASB issued ASU 2016-13, 'Measurement of Credit Losses on Financial Instruments', which significantly 
changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit 
losses expected to occur over their remaining life. The ASU is effective for public business entities that are SEC filers for interim 
and annual periods in fiscal years beginning after December 15, 2019. The adoption of ASU 2016-13 is not expected to have a 
significant impact on the financial statements.

In  July  2018,  the  FASB  issued ASU  2018-09,  which  clarifies  and  corrects  unintended  application  of  guidance,  and  makes 
improvements to several Codification Topics. The changes are part of an ongoing FASB project to make non-substantive technical 
corrections, clarifications, and improvements that are not expected to have a significant effect on accounting practice or create a 
significant administrative cost to most entities.
Most of the amendments are effective immediately. 
Some of the amendments are effective for:
Public business entities for annual and interim periods in fiscal years beginning after December 15, 2018.
• 
All other entities for annual periods in fiscal years beginning after December 15, 2019, and interim periods in fiscal years 
• 
beginning after December 15, 2020.  Other amendments, which affect recently issued ASUs that are not yet effective, are effective 
with the original ASU. The impact of adoption of ASU 2018-19 is not expected to be significant.  

In June 2018, the FASB issued ASU 2018-08, which clarifies and improves current guidance about whether a transfer of assets 
(or the reduction, settlement, or cancellation of liabilities) is a contribution or an exchange transaction.  For transactions in which 
an entity is either a public business entity or an NFP that has issued, or is a conduit bond obligor for securities that are traded, 
126

listed, or quoted on an exchange or an over-the-counter market and serves as a resource recipient, the entity should apply the 
amendments in this ASU on contributions received to annual and interim periods in fiscal years beginning after June 15, 2018.   
All other entities should apply the amendments for transactions in which the entity serves as the resource recipient to annual 
periods in fiscal years beginning after December 15, 2018 and interim periods in fiscal years beginning after December 15, 2019.  
For transactions in which an entity is either a public business entity or an NFP that has issued, or is a conduit bond obligor for 
securities that are traded, listed, or quoted on an exchange or an over-the-counter market and serves as a resource provider, the 
entity should apply the amendments in this ASU on contributions made to annual and interim periods in fiscal years beginning 
after December 15, 2018.  All other entities should apply the amendments for transactions in which the entity serves as the resource 
provider for annual periods in fiscal years beginning after December 15, 2019 and interim periods in fiscal years beginning after 
December 15, 2020. Early adoption of the amendments is permitted. The adoption of ASU 2018-08 is not expected to have a 
significant impact on the financial statements. 

In February 2018, the FASB issued ASU 2018-02, which allows a reclassification from accumulated other comprehensive income 
to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. This ASU is effective for all entities for 
annual and interim periods in fiscal years beginning after December 15, 2018. Early adoption is permitted, including adoption in 
any interim period, (1) for public business entities for reporting periods for which financial statements have not yet been issued 
and (2) for all other entities for reporting periods for which financial statements have not yet been made available for issuance.   
The adoption of ASU 2018-02 is not expected to have a significant impact on the financial statements. 

In December 2017, the FASB issued ASU 2017-15. The ASU eliminates Topic 995, which includes an exemption to the recognition 
of deferred taxes on certain statutory reserve deposits that were, but are no longer, tax deferred. This ASU is effective for all entities 
for annual and interim periods in fiscal years beginning after December 15, 2018. Early adoption is permitted for all entities, 
including adoption in an interim period. The adoption of ASU 2017-15 is not expected to have a significant impact on the financial 
statements. 

Impact of other new accounting pronouncements 

In January 2017, the FASB issued ASU 2017-04 'Intangibles - Goodwill and Other: Simplifying the test for goodwill impairment' 
which requires an entity to no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, 
impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. The ASU 
is effective for public businesses, that are SEC filers, for annual and interim periods in fiscal years beginning after December 15, 
2019. The adoption of ASU 2017-04 is not expected to have a significant impact on the financial statements.  

In August 2018, the FASB issued ASU 2018-15, which clarifies that implementation costs incurred by customers in cloud computing 
arrangements are deferred if they would be capitalized by customers in software licensing arrangements under the internal-use 
software guidance.
This ASU is effective for:
• 
• 

Public business entities for annual and interim periods in fiscal years beginning after December 15, 2019.
Early adoption is permitted. Our evaluation of the impact of adoption of ASU 2018-15 is on-going.

24. Related Parties 

Subsidiaries  of  the  Company  earned  revenue  of  $633,000  (2017:  $743,000)  from  DS  Biopharma  Limited  (formerly  Dignity 
Sciences Limited) during the year. Dr. John Climax is Chief Executive Officer and both Dr. John Climax and Dr. Ronan Lambe 
are  Directors  and  shareholders  of  DS  Biopharma  Limited.  $338,000  was  recorded  as  due  from  DS  Biopharma  Limited  at 
December 31, 2018. The contract terms were agreed on an arm’s length basis.

During the year ended December 31, 2017, personal expenses totaling $178,000 were settled by the Company on behalf of Mr. 
Ciaran  Murray.  Payment  was  received  in  advance  from  Mr.  Murray  in  respect  of  these  expenses. The  Company  transferred 
ownership of an asset at fair value ($77,000) to Mr. Ciaran Murray effective November 1, 2017. Payment was received in full in 
January 2018.  

On July 22, 2016, Mr. Thomas Lynch retired as a Director of the Company, having previously resigned as Chairman of the Company 
in March 2016. A charge of  €231,750 was recorded during 2018 in respect of consultancy services provided by a company 
controlled by Mr. Lynch. $64,000 was recorded as due to Mr. Lynch under the terms of the agreement at December 31, 2018. 

25.  Subsequent Events

On January 8, 2019 the Company announced a share buyback program of up to 1 million shares to be executed opportunistically 
during 2019 depending on cash commitments.  All ordinary shares that are redeemed under the buyback program will be cancelled 
in  accordance  with  the  constitutional  documents  of  the  Company  and  the  nominal  value  of  these  shares  transferred  to  an 
undenoninated capital fund as required under Irish Company law.  

On January 25, 2019 a subsidiary of the Company, ICON Laboratory Services Inc.  acquired 100% of the equity share capital of 
MolecularMD Corp. The initial consideration on acquisition is $42 million.   

The Company has evaluated subsequent events from the balance sheet date through March 1, 2019, the date at which the consolidated 
financial statements were available to be issued.  The Company has determined that there are no items , other than the item described 
above, to disclose.  

128

  
26.      Impact of change in accounting policies

The Company adopted ASC 606 ‘Revenue from Contracts with Customers’, with a date of initial application of January 1, 2018. 
The revenue recognition accounting policy applied in preparation of the results for the twelve months ended December 31, 2018
therefore reflect application of ASC 606. ICON has elected to adopt the standard using the cumulative effect transition method.  
Under this transition method, ICON has applied the new standard as at the date of initial application (i.e. January 1, 2018), without 
restatement of comparative amounts. The cumulative effect of initially applying the new standard (to revenue, costs and tax) is 
recorded as an adjustment to the opening balance of equity at the date of initial application. The comparative information has not 
been adjusted and therefore continues to be reported under ASC 605 ‘Revenue Recognition’. 

The new standard requires application of five steps: (1) identify the contract(s) with a customer; (2) identify the performance 
obligation in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in 
the contract; and (5) recognize revenue when (or as) the entity satisfies the performance obligation.  

The most significant impact of application of the standard relates to our assessment of performance and percentage of completion 
in respect of our clinical trial service revenue. Prior to application of ASC 606, the revenue attributable to performance was 
determined based on both input and output  methods of measurement. We have concluded that under the new standard, a clinical 
trial  service  is  a  single  performance  obligation  satisfied  over  time  i.e.  the  full  service  obligation  in  respect  of  a  clinical trial 
(including those services performed by investigators and other parties) is considered a single performance obligation. Promises 
offered to the customer are not distinct within the context of the contract. We have concluded that ICON is the contract principal 
in respect of both direct services and in the use of third parties (principally investigator services) that support the clinical research 
project. The transaction price is determined by reference to the contract or change order value (total service revenue and pass-
through/ reimbursable expenses) adjusted to reflect a realizable contract value. Revenue is  recognized as the single performance 
obligation is satisfied. The progress towards completion for clinical service contracts is measured based on an input measure being 
total project costs (inclusive of third party costs) at each reporting period.

Incremental costs of obtaining a contract were also considered on adoption of ASC 606. Commission costs of $12 million were 
recognized as an asset on the Consolidated Balance Sheet in respect of those contracts that exceed one year. Where commission 
costs relate to contracts that are less than one year, the practical expedient is applied as the amortization period of the asset which 
would arise on deferral would be one year or less. 

A deferred tax asset of $6.9 million was recognized in respect of the timing differences arising from cumulative impact of non tax 
adjustments recorded on adoption of ASC 606. These are expected to reverse in future periods.

The tables on the pages following summarize the impact of adopting ASC 606 on the consolidated financial statements for the  
twelve months ended December 31, 2018.
