Not applicable. Item 2. Offer Statistics and Expected Timetable. Not applicable. Item 3. Key Information. A. 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 financial statements and financial information in the sections following are prepared in accordance with the accounting policies (see note 2 - Significant accounting policies in the consolidated financial statements). The significant changes in accounting policies adopted during the years ended December 31, 2019 and December 31, 2018 are set-out in the paragraphs following. ASC 842 'Leases' became effective for ICON plc with effect from January 1, 2019. ICON plc adopted the new standard as of January 1, 2019 under the cumulative-effect adjustment approach. Under this transition method, the new standard is applied without restatement of comparative period amounts. A lease liability and right-of-use asset have been recorded on the Consolidated Balance Sheet as at January 1, 2019 of $106.5 million (see note 2 - Significant accounting policies in the consolidated financial statements). The net operating cost of leases recorded during the year ended December 31, 2019 was $33.0 million, (see note 22 - Operating leases in the consolidated financial statements). The Company adopted ASC 606 'Revenue from Contracts with Customers' (ASC 606) on 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 and the twelve months ended December 31, 2019. As ICON adopted the standard using the cumulative effect transition method, there was no restatement of comparative amounts. Therefore, the results for the year ended December 31, 2017 and previously reflect the provisions of ASC 605 'Revenue Recognition'. The most significant impact of application of the new standard was 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 Consolidated Statements 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 (exclusive of revenue from reimbursable expenses). This treatment is consistent with the adoption of ASC 606 from January 1, 2018 without restatement of comparatives. On May 23, 2019 a subsidiary of the Company, ICON Clinical Research (U.K.) Limited, acquired a majority shareholding in MeDiNova Research ("MeDiNova"), a site network with research sites in key markets in Europe and Africa. ICON has the right to acquire the remaining shares in the company during 2020. The vendors also have a right to sell the remaining shares to ICON during 2020. The acquisition of MeDiNova has been accounted for as a business combination in accordance with ASC 805 'Business Combinations'. The minority put/call arrangement is required to be presented separately as a redeemable noncontrolling interest on the Consolidated Balance Sheet. This classification reflects the assessment that the instruments are contingently redeemable and the change in the redemption value, above or below the amount recorded as net income attributable to noncontrolling interest, is recorded directly within retained earnings. In calculating basic and diluted earnings per share, the adjustment to reflect changes in the redemption amount of the noncontrolling interest is included in net income attributable to the Group (see note 26 - Net income per ordinary share in the consolidated financial statements). 2 Statement of Operations Data: Revenue/gross revenue Reimbursable expenses (1) Costs and expenses: Direct costs (1) Selling, general and administrative Depreciation and amortization Restructuring and other items (2),(3),(4) Total costs and expenses Income from operations Net interest expense Income before provision for income taxes Provision for income taxes Net income attributable to noncontrolling interest Net income attributable to the Group Net income per ordinary share attributable to the Group (5): Basic Diluted Adjusted net income per Ordinary Share attributable to the Group (6): Basic Diluted Weighted average number of ordinary shares outstanding: Basic Diluted Balance Sheet Data: Cash and cash equivalents Available for sale investments Working capital Total assets Non-current other liabilities Non-current government grants Ordinary share capital Additional paid-in capital Shareholders’ equity Year Ended December 31, 2019 2018 2017 2016 2015 (in thousands, except share and per share data) $ 2,805,839 $ 2,595,777 $ 2,402,321 $ 2,364,956 $ 2,161,618 — — (643,882) (698,469) (586,640) 1,758,439 1,666,487 1,574,978 1,974,135 1,818,220 1,027,310 336,748 61,550 325,794 65,916 323,741 61,297 961,333 325,726 59,575 908,979 326,786 57,677 — 12,490 7,753 8,159 — 2,372,433 2,222,420 1,420,101 1,354,793 1,293,442 433,406 (6,417) 426,989 (51,133) 373,357 (8,743) 364,614 (41,958) 338,338 (10,281) 328,057 (46,569) 311,694 (11,522) 300,172 (37,993) 281,536 (2,686) 278,850 (39,311) (1,870) — — — — $ 373,986 $ 322,656 $ 281,488 $ 262,179 $ 239,539 $ $ $ $ 6.85 $ 6.79 $ 5.96 $ 5.89 $ 5.20 $ 5.13 $ 4.75 $ 4.65 $ 6.94 $ 6.88 $ 5.96 $ 5.89 $ 5.20 $ 5.13 $ 4.75 $ 4.65 $ 4.08 3.97 4.08 3.97 53,859,537 54,118,764 54,129,439 55,248,900 58,746,935 54,333,461 54,790,663 54,849,046 56,407,136 60,290,033 Year Ended December 31, 2019 2018 2017 2016 2015 (in thousands) $ 520,309 $ 395,851 $ 282,859 $ 192,541 $ 103,911 49,628 493,728 59,910 719,560 77,589 534,960 68,046 463,552 85,990 290,939 2,907,512 2,354,255 2,146,618 1,825,843 1,717,209 17,512 813 4,635 13,446 877 4,658 17,111 966 4,664 577,961 529,642 481,337 1,618,055 1,354,281 1,191,000 23,752 887 4,692 438,126 945,174 12,224 959 4,719 383,355 763,096 3 (1) Reimbursable expenses are comprised of payments to investigators and certain other costs reimbursed by clients under terms specific to each of the Company’s contracts (see note 2 (e) - Significant accounting policies in the consolidated financial statements). (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 - Restructuring charges in the 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 - Restructuring charges in the 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 - Restructuring charges in the consolidated financial statements). (5) Net income per ordinary share is based on the weighted average number of outstanding ordinary shares. Diluted net income per share includes potential ordinary shares from the exercise of options, RSUs and PSUs. (6) Adjusted net income per ordinary share reflects the add back of the adjustment to bring the noncontrolling interest in MeDiNova to the expected redemption amount. The value of the accretion recorded directly to equity of $5.0 million has been excluded from net income for the year ended December 31, 2019 when calculating adjusted net income per ordinary share attributable to the Group (non-GAAP). This redemption value is required to be included in the calculation of EPS (GAAP). (See note 26 - Net Income per Ordinary Share in the consolidated financial statements). B. Capitalization and indebtedness Not applicable C. Reasons for the offer and use of proceeds Not applicable D. Risk Factors Various risk factors that are relevant to our business and the services we provide are outlined below. The occurrence of any of these events may materially and adversely affect our business operations, financial condition and results of operations and future prospects. 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, 2019 37.6% of our revenues were derived from our top five customers, with two customers contributing more than 10% of our revenues during the period (the largest contributing 12.5% and the second largest contributing 10.2%). 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 during this period (see note 16 - Disaggregation of revenue in the consolidated financial statements). 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%). No other customer contributed more than 10% of our revenues during this period. 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. 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 (see note 16 - Disaggregation of revenue in the consolidated financial statements). 4 Our financial results may be adversely impacted if we under price our contracts, overrun our cost estimates or fail to receive approval for or experience delays in documenting change orders. Many of our contracts are long-term fixed price or fixed unit price contracts for services. As a result, variations in the timing and progress of large contracts may materially adversely affect our results of operations. Revenue recognized on these service contracts are based on an assessment of progress towards completion being the cost of time and other third party costs as a percentage of total estimated time and other third party costs to deliver our services. As a result, variations in the timing and progress of large contracts may materially adversely affect our results of operations. Estimating time and costs to complete requires judgment and includes consideration of 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. We regularly review 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. We bear the risk of cost overruns unless the scope of activity is revised from the contract specifications and we are able to negotiate a contract modification. We endeavor to ensure that any changes in scope are appropriately monitored and change orders or contract modifications are promptly negotiated and documented for changes in scope. 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. The potential loss or delay of our large contracts or of multiple contracts could adversely affect our results 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 canceled 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. As a result, contract terminations, delays or other changes are part of our clinical services business. In the event of termination, our contracts often provide for fees for winding down the trial but these fees may not be sufficient for us to maintain our margins, and termination may result in lower resource utilization rates. In addition, we may not realize the full benefits of our backlog of contractually committed services if our clients cancel, delay or reduce their commitments under our contracts with them. Therefore, the loss, early termination or delay of a large contract or contracts could adversely affect our revenues and profitability. If we do not generate new business awards, or if new business awards are delayed, terminated, reduced in scope or fail to go to contract, our business, financial conditions, results of operations or cash flows may be materially adversely affected. Our business is dependent on our ability to generate new business awards from new and existing customers and maintain existing customer contracts. If we were unable to generate new business awards on a timely basis and contract for those awards, that could have a material impact on our business, financial condition, results of operations or cash flows. If we are unable to successfully develop and market new services or enter new markets, our growth, results of operations or financial condition could be adversely affected. A key element of our growth strategy is the successful development and marketing of new services or entering new markets that complement or expand our existing business. As we develop new services or enter new markets, we may not have or adequately build the competencies necessary to perform such services satisfactorily, may not receive market acceptance for such services or may face increased competition. If we are unable to succeed in developing new services, entering new markets or attracting a client base for our new services or in new markets, we will be unable to implement this element of our growth strategy, and our future business, reputation, results of operations could be adversely impacted. 5 If we fail to attract or retain key personnel, 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 people. 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, enrollment and retention. Our site and patient solutions group includes upfront planning of site and patient management including identification, enrollment 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 enrollment 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. During 2019, we further enhanced our site and patient recruitment abilities through the strategic acquisitions of MeDiNova and CRN Holdings, LLC (trading as Symphony Clinical Research ("Symphony"). We also use digital solutions to drive site performance, including pre-screening, eConsent, learning management, document tracking and management with key applications. 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. 6 Climate change, extreme weather events, earthquakes and other natural disasters could adversely affect our business. In recent years, extreme weather events and changing weather patterns such as storms, flooding, droughts and temperature changes have become more common. As a result, we are potentially exposed to varying natural disaster or extreme weather risks such as hurricanes, tornadoes, droughts or floods, or other events that may result from the impact of climate change on the environment, such as sea level rise. As a result, we could experience increased costs, business interruptions, destruction of facilities, and loss of life, all of which could have a material adverse effect on our business, financial condition, or results of operations. The potential impacts of climate change may also include increased operating costs associated with additional regulatory requirements and investments in reducing energy, water use and greenhouse gas emissions. A disease outbreak, epidemic or pandemic could adversely affect our business performance. A disease outbreak, such as influenza, coronavirus, or other biological attack could negatively impact our operations. We could experience restrictions on our ability to travel, or the ability of patients or other service providers to travel, to monitor our clinical trials and to ensure laboratory samples are collected and analyzed on time as a result of an outbreak. At this point in time, there is significant uncertainty relating to the potential effect of the coronavirus on our business. Infections may become more widespread, including to countries where we have operations, and travel restrictions may remain or worsen, all of which could have a material adverse effect on our business, financial condition or results of operations. The potential impact of an epidemic or pandemic may also result in increased operating costs and result in a requirement to increase investment in impact prevention. 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 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 the termination of one or more contracts, 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. 7 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. Failure to meet productivity objectives under our business improvement objectives could adversely impact our competitiveness and therefore our operating results. We continue to pursue business transformation initiatives to embed technology, innovation and deliver operational efficiencies. As part of these initiatives, we seek to improve our productivity, flexibility, quality, functionality and cost savings by our on-going investment in global technologies, continuous improvement of our business processes and functions to deliver economies of scale. These initiatives may not deliver their intended gains or be completed in a timely manner which may adversely impact our competitiveness and our ability to meet our growth objectives and therefore, could adversely affect our business and operating results, 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. A failure to identify and successfully close and integrate strategic acquisition targets could adversely impact our ongoing business and financial results. We have made a number of acquisitions and 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. 8 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. 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. 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 infringement or other legal processing related to intellectual property could have a material adverse effect on our operations and financial condition. We act as authorized representative and legal representative for some clients pursuant to certain EU legislation We act as authorized representative pursuant to Medical Devices Directive 93/42/EEC (“MDD”) and Active Implantable Medical Devices Directive 90/385/EEC (“AIMD”) for certain clients who are located outside of the European Union. Medical Devices Regulation 2017/745 (“MDR”) will replace MDD on May 26, 2020 and provides for increased responsibility, and accordingly increased risk, for authorized representatives. As authorized representative, we act on behalf of medical device manufacturers in relation to specified tasks with regard to their obligations under MDR. 9 We also act as legal representative pursuant to MDD and AIMD, and will continue to do so pursuant to MDR, for certain clients who are located outside of the European Union with respect to clinical trials being carried out by those clients in the European Union. As legal representative, we are responsible for ensuring compliance with the client’s obligations pursuant to MDR and we are the addressee for all communications with the client provided for under MDR. We provide these services subject to certain terms and conditions which are contained in our agreements with clients pertaining to these services. We aim to reduce any potential liability associated with these activities by seeking contractual indemnification from our clients and by maintaining an appropriate level of insurance cover. However, there is no guarantee that the specific insurance will be available or that a client will fulfill its obligations in relation to their indemnity. Risk Related to Our Industry Outsourcing trends in the pharmaceutical, biotechnology and medical device industries and changes in spending and research and development budgets could adversely affect our operating results and growth rates. 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. New entrants may also enter the market which would further increase competition and could adversely affect our business and operations. 10 We may be adversely affected by industry, customer or therapeutic concentration. We provide services to biopharmaceutical, biotechnology, medical device and government organizations and our revenue is dependent on expenditures by these customers. Our business could therefore be adversely impacted by mergers, consolidation, business failures, distress in financial markets or other factors resulting in a decrease in the number of potential customers or therapeutic products being developed through the drug development progress. There has been consolidation in the biopharmaceutical market in recent years. If the number of our potential customers were to decline in the future, they may be able to negotiate price discounts or other terms for services that are less favorable to us than they have been historically. 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. They may fall short of prior periods, our projections or the expectations of securities analysts or investors, which may adversely affect the market price of our stock. 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 backlog may not convert to revenue and the rate of conversion may slow. Our backlog is that element of 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 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 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. 11 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. In the year ended December 31, 2018 we applied ASC 606 'Revenue from contracts with customers' for the first time with effect from January 1, 2018. Under this 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 total project costs (inclusive of third party costs). That estimate is required to be updated on an on-going basis to project completion. 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' at January 1, 2019 results in the recognition of a lease liability and right-of-use asset on the Consolidated Balance Sheet (see note 28 - Impact of change in accounting policies in the consolidated financial statements). 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. 12 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 (EU). In October 2019, a Brexit deal was agreed in principle. The UK have left the EU with effect from January 31, 2020 and have entered an eleven month transition period which will end on December 31, 2020. The British government continues to negotiate the terms of the U.K.’s future relationship with the EU. The terms of the withdrawal agreement continue to be unknown however it is likely that there will be greater restrictions on trade and the transfer of goods and other items (including lab samples) between the U.K. and EU. 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 900 people in the U.K. The announcement of Brexit and continued uncertainty around the withdrawal terms caused volatility in global stock markets and exchange rates. Continued fluctuation in 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. 13 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. 14 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, 2019 and December 31, 2018, we had an outstanding principal amount of indebtedness of $350 million under our $350 million Note Purchase and Guarantee Agreement or ‘Senior Notes’ entered into on December 15, 2015. The Senior Notes will mature on December 15, 2020. 15 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, 2019. This facility bears interest at LIBOR plus a margin. We continue to monitor the phasing out of LIBOR which is currently scheduled for 2021. 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. We also continue to monitor the communications from the FASB in relation to this issue and await further communications following the issuance of the proposed accounting standards update - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting on September 5, 2019. 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. 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 in the Note Purchase and Guarantee Agreement. Our ability to comply with these financial covenants may be affected by events beyond our control. 16 Interest rate fluctuations may materially adversely affect our results of operations and financial conditions 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 the Revolving Credit Facility at December 31, 2019. We continue to monitor the phasing out of LIBOR which is 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 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: • • • • • • • • • • • • • • • general market and economic conditions; our results of operations; issuance of new or changed securities analysts’ reports or recommendations; developments impacting the industry or our competitors; introduction of new products or services by us or our competitors; the public's reaction to our press releases, our other public announcements and our filings with the SEC; guidance, if any, that we provide to the public, any changes in this guidance or failure to meet this guidance; changes in the credit rating of our debt; sale, or anticipated sale, of large blocks of our stock; additions or departures of key personnel; regulatory or political developments; litigation and governmental investigations; changing economic conditions; exchange rate fluctuations; and other events or factors, including those resulting from natural disasters, war, acts of terrorism or responses to those events. In addition, stock markets have from time to time experienced significant price and volume fluctuations unrelated to the operating performance of particular companies. Future fluctuations in stock markets may lead to volatility in the market price of our common stock which could lead to losses by investors. If securities analysts or industry analysts do not publish reports about our business or if they downgrade our stock or our sector, our stock price and trading volumes could decline. The trading market for common stock depends in part on the research and reports that industry or financial analysts publish about us, our business or industry. We do not control these analysts. If one or more of the analysts who do cover us downgrade our stock or our industry or the stock of any of our competitors, or publish inaccurate or unfavorable research about our business or industry, the price of our stock could decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, we could lose visibility in the market, which in turn could cause our stock price or trading volume to decline. 17 Your investment return may be reduced if we lose our foreign private issuer status. We are a “foreign private issuer,” as such term is defined in Rule 405 under the U.S. Securities Act 1933, and, therefore, we are not required to file quarterly reports on Form 10-Q or current reports on Form 8-K with the SEC. In addition, the proxy rules and Section 16 reporting and short-swing profit recapture rules are not applicable to us. If we lose our status as a foreign private issuer by our election or otherwise and we become subject to the full reporting regime of the United States securities laws, we will be subject to additional reporting obligations and proxy solicitation obligations under the Exchange Act and our officers, directors and 10% shareholders would become subject to the short-swing profit rules. The imposition of these reporting rules would increase our costs and the obligations of those affected by the short-swing rules. We do not expect to pay any cash dividends for the foreseeable future. We currently do not expect to declare dividends on our common stock and have not done so in the past. We continue to anticipate that our earnings will be used to provide working capital, to support operations and to finance the growth and development of our business. They may also be used to continue our share repurchase program. Any determination to declare or pay dividends in the future will be at the discretion of our board of directors, subject to relevant laws and dependent on a number of factors, including our earnings, capital requirements and overall financial condition. Therefore, the only opportunity for stockholders to achieve a return on their investment may be if the market price of our common stock appreciates and shares are sold at a profit. The market price for our common stock may not appreciate and may fall below the price stockholders paid for such common stock. Environmental, social and governance matters may impact our business and reputation. Increasingly, in addition to the importance of their financial performance, companies are being judged by their performance on a variety of environmental, social and governance ('ESG') matters, which are considered to contribute to the long-term sustainability of companies’ performance. A variety of organizations measure the performance of companies on such ESG topics, and the results of these assessments are widely publicized. In addition, investment in funds that specialize in companies that perform well in such assessments are increasingly popular, and major institutional investors have publicly emphasized the importance of such ESG measures to their investment decisions. Topics taken into account in such assessments include, among others, the company’s efforts and impacts on climate change and human rights, ethics and compliance with law, and the role of the company’s board of directors in supervising various sustainability issues. We actively manage a broad range of such ESG matters, taking into consideration their expected impact on the sustainability of our business over time, and the potential impact of our business on society and the environment. However, in light of investors’ increased focus on ESG matters, there can be no certainty that we will manage such issues successfully, or that we will successfully meet society’s perceived expectations as to our proper role. Any failure or perceived failure by us in this regard could have a material adverse effect on our reputation and on our business, share price, financial condition, or results of operations, including the sustainability of our business over time.

Mapi Group has over 40 years of experience supporting Life-Science companies as the world leading Patient-Centered Research Company in commercializing novel treatments through Real-World Evidence, Strategic Regulatory Services, Pharmacovigilance, Market Access and Language Services. Mapi Group is the premier provider of Health Research and Commercialization services to Life-Science companies enabling Market Authorization, Market Access and Market Adoption of novel therapeutics. Cash outflows on acquisition were $145.8 million (see note 4 - Goodwill in the consolidated financial statements). The acquisition of Mapi Group strengthened commercialization presence, analytics, real world evidence generation and strategic regulatory services. ICON’s existing commercialization and outcomes research business adding significant Business Overview ICON is a leading global provider of outsourced development and commercialization services to pharmaceutical, biotechnology, medical device, and government and public health organizations. We offer a full range of clinical, consulting and commercial services that range from clinical development strategy, planning and trial design, to full study execution, and post-market commercialization. ICON provides its services across a range of clinical outsourcing operating models including strategic partnerships, preferred provider, full service delivery to functional service provision and stand-alone services. 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. We earn revenue by providing a number of different services to our customers. Those services are integral components of the clinical development process, include clinical trial management, consulting, contract staffing and laboratory services. 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 the 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, 2019, we employed approximately 14,650 employees in 97 locations in 40 countries. During the year ended December 31, 2019, we derived approximately 31.8%, 58.5% and 9.7% of our revenue in the United States, Europe and Rest of World, respectively (see note 19 - Business Segment and Geographical Information in the consolidated financial statements). The ICON Strategy We have achieved strong growth since our foundation in 1990, as a global provider of outsourced development and commercialization services to pharmaceutical, biotechnology, medical device and government and public health organizations. We focus our innovation on those factors that are critical to our clients - reducing time to market, reducing cost and increasing quality. Our global team has extensive experience in a broad range of therapeutic areas. ICON has been recognized as one of the world's leading Contract Research Organizations (''CROs") through a number of high-profile industry awards. 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. 20 We expect that continued 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 Market Focus We continue to focus on expanding and deepening our partnerships with existing customers, while also developing new customer relationships. 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. During the year, the Group acquired MMD, MeDiNova and Symphony who will enhance ICON’s capabilities across multiple platforms and strengthen our value proposition to clients; particularly in our laboratory and site network services. ICON has a focused patient, site and data strategy, which is helping us to improve site identification, study placement and patient recruitment and retention. A successful element of our strategy has been our integrated site network made up of PMG, MeDiNova and Symphony and our ability to grow alliances with third party sites and healthcare institutions in the US and Europe. These acquisitions further enhance ICON’s site network in the US and EMEA and strengthen our patient recruitment capabilities to help recruit patients into studies faster. Please refer to Item 4 Information on the Company, for further details of these acquisitions. 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. 21 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. ADDPLAN is used by regulatory agencies (FDA, EMA (Europe) and PMDA (Japan), top pharmaceuticals, medical device companies, and academia. Finding and engaging suitable patients to conduct clinical trials is one of the biggest issues facing the 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, MeDiNova and Symphony 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. One Search is our intuitive, integrated workflow and interrogation tool that enables access to multiple data sources and provides the visualization and tools necessary for optimum site identification based on ICON and industry data of capability, experience and performance. Scoring on enrollment performance, speed of start-up and quality supports better site selection. 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 also deploy 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 enables us to enhance the service levels across these support areas whilst driving down the costs of the 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 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. 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. 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 2019, 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. 22 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 2019 with the acquisitions of MeDiNova and Symphony during the year along with the 2018 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 Innovation at ICON is focused on the factors that are critical to our clients. We develop integrated technologies to significantly enhance the efficiency and productivity of clients’ drug and device development programs, providing true transparency across all areas of a study. 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. In addition to our ICONIK platform and ADDPLAN software (see details on page 22), 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. For additional details on our information systems and applied innovation see the Information System section on page 35. 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.

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. 24 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. 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. 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. 25 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 2019 was approximately $35 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 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. Leveraging differentiated technology solutions and data collaborations drives better execution in clinical trials. 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. See further details on our new technologies and innovations in the section on information systems on page 35. 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. 26 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 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. 27 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. 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. Sustainability and Environmental Management Environmental, Social and Governance Our mission is to help our customers accelerate the development of drugs and devices that save lives and improve the quality of life. We help our customers deliver life-changing medicines by being innovative in our solutions, collaborative in how we work as teams, accountable for the results we achieve and committed to doing the right thing for our customers and the patients they serve. Our business model is described in the sections preceding this. Our core values underpin our mission and drive a culture and mind-set of ownership at ICON. “Own it @ ICON” is how we define our culture. Our culture of ownership connects us to the core values at the heart of the Company and helps us differentiate how we work with our customers to achieve their goals. Our values are: Accountability & delivery: We take pride in what we do • • Collaboration: We are one team • • Partnership: We partner with our customers Integrity: We do the right thing 28 Our values underpin how we work together to deliver on our mission to help our customers accelerate the development of drugs and devices that save lives and improve the quality of life. These values and our Code of Ethical Conduct, which underpins these values, form the core of what we do and how we do it. It applies to all officers, directors, employees, consultants and agents globally. All employees and temporary workers are mandated to complete global ethics training. During 2019, ICON established an Environmental, Social, and Governance Committee ('ESG Committee'). The ESG Committee is chaired by the Chief Administrative Officer ('CAO') of the Group. The CAO is responsible for reporting to the ICON management leadership team and Board on ESG matters. The purpose of the ESG Committee is to support the Company's on-going commitment to the environment, social matters, health and safety, corporate social responsibility, corporate governance, sustainability and other public policy matters relevant to the Company. The ESG Committee is a cross-functional management committee of the Company with representation from facilities, corporate communications, finance, legal, investor relations and human resources departments. The Committee assists and supports executive management and the Board of the Company in; • • determining and setting the strategy relating to ESG matters and developing, implementing and monitoring initiatives and policies based on that strategy ICON is committed to delivering excellence and care to the communities in which we operate. This includes conducting our business in an environmentally sustainable manner as set out in our Global Code of Ethical Conduct. We achieve this by managing and improving our environmental performance across all business activities. Our employees, directors, officers, contractors, and temporary workers are expected to support our sustainability objectives. As a Clinical Research Organization, we recognize the impact of how we operate on the environment in the following key areas: • • • • • • energy use; waste generation; emissions to air/water; water use; transport; and procurement. Our Global Environmental Management Policy and Environmental Management Plan were approved during 2018. Our Environmental Management Plan and Performance Statement sets out the environmental actions and targets we will carry out to ensure compliance with our Global Environmental Management Policy and to engage our employees in supporting our objectives for continued improvement. Our Environmental Performance Statement is available to employees and our customers. The plan sets out our commitment to conducting our business in an environmentally sustainable manner by managing and improving our environmental performance across all business activities. Our plan sets out our initiatives and goals for the next four years. Responsibilities for the implementation of our objectives and co-ordination of our sustainability efforts and reporting on progress to the executive leadership is led by our facilities team, reporting to our Global Chief Administrative Officer and General Counsel, with input from our procurement, global legal, corporate communications and human resources teams through our ESG Committee. 29 We track, calculate and report our carbon footprint and use the information available to continue to improve our processes and reduce our impact. We follow the Greenhouse Gas (GHG) Protocol Corporate Standard, which is the global corporate accounting and reporting standard for calculating carbon emissions. We have more than 80 facilities globally which operate in office buildings, where the primary energy consumption is electricity for light and heating, ventilation and air conditioning systems. Our central laboratories also operate laboratory instruments. Where we have direct control over the buildings we operate, we ensure energy efficient lighting solutions. Where we do not have direct control over our facilities, we work with our landlords and other stakeholders to encourage energy efficient lighting solutions. We also work hard to extend the useful life of our equipment and ensure appropriate disposal of assets when decommissioned. Our people are expected to support our waste management and disposal programs and one of the goals of our environmental management policy is to reduce our impact. During 2018 we commenced the development of a global waste management system, which has been maintained during 2019. Reflecting our continued commitment to sustainable practices, we have included an annual 'sustainability month' in our calendar since 2017. The focus of the month is to promote best practices and highlight sustainable activities across all of our offices and locations. This focus together with the introduction of increased recycling facilities at our key sites contributed to our objectives to reduce waste during 2019. We continue to work to increase the number of our offices engaging in waste reduction strategies in all areas. We have replaced disposable coffee cups with reusable alternatives and developed objectives relating to reduced paper consumption through the use of electronic documents and signatures. We actively promote the use of technology and teleconferencing facilities in our efforts to reduce travel and commuting activities. During sustainability month, our people were encouraged to car share and utilize public transport. We include air travel miles in our carbon footprint monitoring. Our internal portals include a MyICON page on Environment and Sustainability which reflects policy, practice, promotions and updates on our commitment to sustainability. We also require our suppliers to abide by our Global Supplier Code of Conduct which includes a commitment to comply with applicable environmental laws and regulations, our expectations around waste management and sustainable use of resources. Corporate Social Responsibility Our Corporate Social Responsibility ('CSR') initiatives are aligned with ICON’s values. ICON supports a variety of CSR programs. Our programs aim to make a positive difference to the communities in which we work and live and also recognize the enthusiasm and creativity of our people in their efforts to give something back to their communities. Our CSR activities are focused on two core areas: • • Supporting education & building closer ties between industry & academia; and Improving the welfare of people in the communities in which we live. Supporting education & building closer ties between industry & academia ICON is a strong supporter of bridging the ties between industry and academia and inspiring the next generation of business and scientific leaders. • Benefactor through the Centuries of Trinity College Dublin - In February 2020, ICON was recognized as a benefactor of Trinity College Dublin in recognition of the creation of the ICON McKeon Research Fellowship in Motor Neuron Disease in recognition of Mr. Declan McKeon, former Board member, acting Chairman, Lead Independent Director and Chair of the ICON Audit committee. The ICON-McKeon Research Fellow in MND will carry out research in the areas of machine- learning and artificial intelligence to derive insights from multimodal clinical, imaging neuro-electric signaling, in the context of the neurodegenerative disease of ALS. • • Strategic Partnership with University College Dublin. ICON has been engaged in a strategic partnership with UCD since 2012, which has been heralded as a model for industry-academia collaboration. Scholarships supporting female GAA players. ICON has a partnership with the Women’s Gaelic Players Association, whereby we provide ICON-GPA Life Sciences Scholarships to inter-county football and camogie players engaged in undergraduate and post-graduate life sciences courses. ICON also provides mentoring to players to help them on their career journeys. 30 • • Partnership with Junior Achievement to inspire schoolchildren. ICON supports our people who take time out of their working day over a period of 5 weeks to deliver Junior Achievement educational programs. Junior Achievement encourages young people to remain in education and teaches them the skills they need to succeed in a changing world. Our volunteers teach primary and secondary level students valuable business, STEM and entrepreneurship skills that will stand them in good stead as they progress through education and beyond. Science Gallery Founding Partner. ICON has been a lead corporate supporter of the Science Gallery at Trinity College Dublin since its inception in 2008. Science Gallery aims to inspire and transform curious minds through engagement with science. Improving the welfare of people in the communities in which we live ICON employees across the world are making a positive difference to their communities. We support causes that are important to our employees and have a number of programs that support the welfare of people in our local communities. These include: • Corporate donations to employee-nominated charities. In 2019, ICON supported 10 charities across the world which are supporting people living in poverty, who are suffering from a variety of diseases, are the victims of domestic violence, or natural disasters. Over the last five years, ICON has supported over 60 charities across the world. • Donations in support of employee fundraising. ICON employees raise significant amounts for a variety of charities each year through in-house fundraising events. ICON recognizes the enormous effort and creativity of our employees who fundraise for causes that are important to them by supplementing monies raised through ICON’s Charitable Donation Program. At the core of our strategy is our people As set-out above, one of our four strategic pillars is 'Talent, Leadership Development and Culture'. 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. The training and development of our staff is a key focus for us We have a comprehensive curriculum in place to support our people in their roles. We have invested in creating an innovative learning environment delivered through ICON’s training and development group. All of our people are required to complete mandatory training in key areas which support our values and our way of working. They include (but are not limited to) the following areas: • Global ethics compliance; • Data protection and procedures; • • Confidentiality and maintaining communications; and • Social media usage. IT security; We have a well-established Graduate Development Program for our clinical teams, which now runs in the US, China, Japan, South Korea and also Australia where we take recent graduates and prepare them for careers in clinical monitoring and data management. We also have formed collaboration with University College Dublin which enables ICON to provide customized management and development programs for global employees. These programs are focused on leadership development for those people in 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. Our learning and development program is 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 program contribute to the enhanced retention of our employees, better project deliverables for our customers and the enhanced financial performance of the business. 31 Individual development is supported through formal learning with our personal effectiveness series and via access to our Career Hub portal. Our people can access a wealth of learning materials including courses, resources, toolkits, library items and blogs to support the development of key competencies and improving their eligibility for future roles through these tools. Career Hub also allows employees to understand and explore possible career paths and career opportunities available to them across the organization and provides full transparency to all levels, skills and capabilities required for every role in ICON. ICON is proud of this investment in our people. This investment translated to approximately four days training for each person during 2019. We are also committed to supporting the career aspirations of our people. Approximately 30% of all roles are filled internally. As an organization we are keen to hear directly from our employees Biennially we conduct a global employee engagement survey. Our most recent survey was conducted in October 2018 and had an 88% response rate. There are two key measures which we track closely. The first is Employee Engagement which scored well at 70%, and was on par with the General Industry benchmark. The second is Employee Enablement, which also scored at 70%, 3% above the General Industry benchmark. After each survey we engage in action planning with our people to address areas they have highlighted as important for improvement. The last five years have shown a positive trend for both our engagement and enablement scores. We completed an updated pulse survey during 2019 and a further global employee engagement survey will be completed in 2020. Difference drives innovative thinking and is critical to our success We believe difference drives innovative thinking, which is critical to our customers, and as a global company with approximately 14,650 employees in 40 countries, we encourage diversity of all kinds. We have grown rapidly, increasing our headcount by more than fifty percent over the past 7 years. As a truly global operation, we are deliberately structured as international teams so that we can support the delivery of our customers' clinical development programs across multiple geographies. Recruitment, selection and promotion decisions are merit-based and in line with the principles of reaching a wider talent pool and equal opportunity. Building an inclusive workplace We believe that difference drives innovative thinking and therefore is critical to our success. During 2019 we established the ICON Diversity & Inclusion Steering Group. This Steering Group is comprised of six members of our Group executive team. The executive leaders are supported by senior members of our human resources group. At ICON, our leadership team sees diversity and inclusion in the workplace as at the core of how we work. We recognize the importance of ensuring it is built into every aspect of the talent and employee life cycle. The three core principles which are grounded in our values are; • Diversity - we value difference of gender, race, ethnicity, culture and experience. We believe diversity of thought is what • • drives high performing teams to create better solutions and deliver better outcomes for our customers. Equality - we ensure all employees are treated fairly and equitably with no barriers to career opportunities. We are committed to equal opportunities for all employees and reflect this in our policies and practices. Inclusion - we are a values-driven organization that promotes dignity and respect in all interactions with our customers, our teams and each other. We take pride in our collaborative and inclusive culture where everyone can bring their best selves to their work and deliver the best performance for our customers and patients. The Executive leadership group defined areas of focus for our Diversity & Inclusion agenda for 2019, which continue into 2020 and against which success will be measured. These key areas of focus are around talent management, country level inclusion policies, reward, training, communications and a renewed focus on culture. Our immediate areas of focus around driving inclusion and diversity include: • Training and Development - Under our Diversity and Inclusion Program, we train all our people leaders to understand unconscious bias and similarity bias and also how to encourage diversity of thought and foster inclusion in their teams. Our diversity and inclusion initiatives were launched at our Company wide Wake up to Culture day during 2019. The fundamentals will be embedded into all people leader programs, and reflect the values upon which we assess performance behaviors. 32 • Talent - We recognize that more diversity in senior leadership increases organizational performance. In 2019 we launched our global Senior Director Leadership Program in addition to our Vice President High Potential program for those people who have been identified as High Performing & High Potential Leaders. These programs focus on core organizational skills that will enable these individuals to increase their readiness for promotion, as well as create a strong internal network of senior leaders who feel empowered to take hold of their careers. These programs will help build and support our development of a diverse and inclusive group of future leaders from within and complements existing senior level programs already in existence in the organization. Early in 2020, our top 100 employees attended 'Inclusive Leadership training'. This training will be rolled out to our wider employee group from 2020. • Recruitment and progression - We continue to strive to source the best talent in our industry from across the world to fill the highly specialized roles required to help bring new drugs to market. Our most senior roles are truly global in nature. Since 2018, we mandated gender balanced short lists for senior leadership appointments across the organization in all markets in which we are located. • Retention - We offer flexible working arrangements that help our people achieve balance. Approximately 45% of our employees work remotely. We also support and facilitate part time working arrangements. Approximately 16% of our people work part-time. We have a bonus program for all employees linked to individual and company performance and also operate a global recognition program where peer to peer recognition and awards take place for employees who go the extra mile. We also recognize and reward employees who reach significant service milestones within the company • Reward - The information relating to pay decisions is hosted through core technology, enabling our people leaders • and employees direct access to information which informs and supports equitable and consistent decision making. We have made significant investment in organization design structures, tools and communications which ensures that we have a gender neutral approach to pay decisions. We pay male and female employees equally for the same or equivalent work. We have worked hard to structure our pay principles to ensure that gender is not a factor in how we deliver rewards. Partnership with Trinity Centre for People with Intellectual Disabilities ('TCPID') - In 2019, we entered into a partnership with the Trinity Centre for people with intellectual disabilities. The TCPID situated within the School of Education, Trinity College Dublin, aims to promote the inclusion of people with intellectual disabilities in education and society. The Center provides people who have intellectual disabilities with the opportunity to participate in a higher education program designed to enhance their capacity to fully participate in society as independent adults. The 2-year education program includes work placements and internships to enable students to experience and participate in the work environment. Human rights ICON is committed to acting ethically and with integrity in all our business dealings. We are committed to human rights and the adoption and pursuit of compliance with the United Nations Guiding Principles on Human Rights. Our business model and our policies are intended to fully comply with applicable human rights legislation in the countries in which we operate. ICON’s Global Supplier Code of Conduct also addresses our zero tolerance stance to slavery and human trafficking. ICON is completely opposed to slavery and human trafficking and will not knowingly support or conduct business with any organization involved in such activities. ICON does not employ anyone below the minimum employment age in the jurisdictions in which we operate. In our Anti-Slavery and Human Trafficking Statement, we set out the measures we are taking to prevent modern slavery in our supply chains, in addition to our own operations. A copy of our Anti-Slavery and Human Trafficking Statement is available on our website at https://investor.iconplc.com. Anti-bribery and Corruption Our anti-bribery/anti-corruption program ('ABAC Program') is a key element of our compliance policy framework, with principles and requirements based on the underlying principal that we do not tolerate bribery or any other form of corruption or fraud. ICON and all ICON directors, employees, consultants and agents (“Covered Persons”) must act in compliance with international laws and regulations relating to bribery, corruption and illicit payments including, the US Foreign Corrupt Practices Act and the UK Bribery Act 2010. In April 2018, ICON was awarded the ISO 37001:2016 certification for its Anti-Bribery Management System having established, implemented, maintained, reviewed and improved an Anti-Bribery Management System that can prevent, detect and mitigate the risk of bribery. Our program is designed to ensure our compliance with anti-corruption laws, including due diligence, training, policies, procedures, and internal controls. 33 There are a number of policies and codes that make up the ABAC Management system including the Global Code of Ethical Conduct, the Global Anti Corruption Compliance Policy, the Ethics Line Charter and the Global Supplier Code of Conduct (together “the Codes”). The Codes are available on our website at https://investor.iconplc.com. All ICON employees are required to complete ICON’s annual Ethics online training, which incorporates the key principles of each of the Codes. The Global Code of Ethical Conduct addresses the core principles underpinning the behavior required of all Covered Persons in our internal interactions with each other and our external dealings with patients, clients, health care professionals, regulators, investors, vendors and other third parties. Violations of the Codes may result in a variety of corrective actions and in some cases may result in disciplinary action up to and including termination of employment. Bribery and corruption remains a business risk as we conduct our business across the globe and enter into partnerships and collaborations. There is no certainty that all employees and third party business partners (including our vendors, suppliers, agents, contractors, and other partners) will comply with anti-bribery laws. When working with third parties, we are committed to working with only those who embrace high standards of ethical behavior consistent with our own. Bribery and corruption risks are a focus of our third-party diligence and management process. We hold our suppliers accountable for meeting their contractual obligations with ICON, including commitments that are made with regard to our Global Supplier Code of Conduct and regulatory compliance. Contract non-compliance can result in termination of the business relationship with the supplier and exclusion from future business with ICON. Suspected violations of the Codes may be reported on a confidential (or anonymous, where permitted) basis in accordance with our Ethics Line Charter through ICON’s Ethics Line. ICON has open door, anti-retaliation policies in place to encourage and protect individuals who raise a concern. Ethics line reports are reported to the Board of ICON plc as appropriate. The Internal Audit team conducts ABAC program audits. Internal Audits focus on testing for compliance and design effectiveness of the overall ABAC program, Internal Audit incorporates an assessment of ABAC measures in all audits, as appropriate. In this approach, bribery and corruption risks are incorporated into the risk assessment and scoping process of each audit. 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 programs, 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. Competition also exists for acquisition candidates in addition to competition for customers. 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, 2019, revenue was earned from over 1,000 clients. During the year ended December 31, 2019, 37.6% of our revenues were derived from our top five customers, with two customers individually contributing more than 10% of our revenues during the period (The largest contributing 12.5% and the second largest contributing 10.2%). No other customer contributed more than 10% of our revenues during this period (see note 16 - Disaggregation of revenue in the consolidated financial statements). 34 During the year ended December 31, 2018, 39.5% of our revenues were derived from our top five customers, with one customer individually contributing more than 10% of our revenues during the period (13.6%). No other customer contributed more than 10% of our revenues during this period. During the year ended December 31, 2017, 42% of our revenues (including reimbursable expenses) were derived from our top five customers, with one customer individually contributing more than 10% of our revenues during the period (21%). No other customer contributed more than 10% of our 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, 2019 we had contracted unsatisfied performance obligations of $5.3 billion (see note 17 - Accounts receivable, unbilled revenue (contract assets) and unearned revenue or payments on account (contract liabilities) in the consolidated financial statements). We believe that our unsatisfied performance obligation 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 unsatisfied performance obligation, and no assurances can be given on the extent to which we will be able to realize this unsatisfied performance obligation as revenue. Information Systems Having access to accurate and timely information is critical in the management, delivery and quality of all aspects of drug development. ICON utilizes an extensive range of both on premise and cloud based applications that support its services including clinical trial design and planning, site start-up, patient consent, site payments, content management, real world evidence generation, customer relationship management (CRM), performance management, compliance and safety reporting and master data management. These solutions are to allow healthcare companies to manage, optimize and execute their clinical and commercial strategies in an orchestrated manner while addressing their regulatory obligations. 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. Data analysis from ICONIK Informatics Hub allows us to enhance the design and delivery of our projects, through stronger engagement with investigators and patients. 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 Dassault. 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 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. 35 We provide interactive response technology (IXR) to enable 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 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. 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 provides its Pharmacovigilance Services using Oracle’s ARGUS safety database, the system is FDA regulation 21 CFR Part 11 compliant and generates all the standard regulatory required reports as well the periodic reports required to support operations. ICON supports Population Pharmacokinetics & Pharmacokinetic Pharmacodynamic modeling though the use of its proprietary software NONMEM®. NONMEM® is a nonlinear mixed effects modeling tool that can be used to fit models to many different types of data. Statistical analysis with NONMEM® using the appropriate model helps pharmaceutical companies determine appropriate dosing strategies for their products, and increase their understanding of drug mechanisms and interactions. NONMEM® can also be accompanied with PDx-Pop proprietary software. 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. All of the Company’s global finance operations utilize Oracle’s eBusiness suite, with the integrated Excel4Apps reporting tool, 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 is evident 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 three data center hubs in Dublin, Ireland; Philadelphia, Pennsylvania and Singapore. These hubs reside within purpose built data center 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 biannually as part of maintaining ICON’s ISO27001:2013 certification. ICON enables its Patient Site and Data Strategy through the services delivered via PMG Research, MeDiNova and Symphony Research where we partner with biopharmaceutical companies and other life science providers (e.g. medical devices companies) to develop and deploy bespoke stakeholder engagement solutions. ICON’s Patient Engagement Services enable site staff to engage directly with patients to help improve their disease and medication understanding through interventional and non- interventional support. Through the acquisition of MMD, ICON now provides molecular diagnostic laboratory capabilities that enables the development and commercialization of precision medicines in oncology, MMD delivers this via the WINDOPATH LIMS software. Other key innovations and new technologies include; • • • 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. PubsHub brings speed and efficiency to medical teams by delivering easy-to-use, web-based solutions that bridge process gaps for system harmonization across companies. ICON utilizes PUBSHUB to automate medical and scientific communications and publications management. The ICON Patient Engagement Platform features an easy to navigate, user friendly website enabling patients to explore new and ongoing studies available, opt-in and connect with their nearest clinical research site. • One Search, an intuitive, integrated workflow and interrogation tool from ICON, enables access to multiple data sources and provides the visualization and tools necessary for optimum site identification based on ICON and industry data of capability, experience and performance. Scoring on enrollment performance, speed of start-up and quality supports better site selection. • 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)). 36 • • • 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. Virtual/Hybrid Trials. Utilizing a combination of ICON developed capabilities in conjunction with commercially available software, ICON brings trials directly to patients, thus allowing diverse and difficult to recruit patient populations to be accessed. APECS - for Investigator Payments ensures timely and accurate payments to sites for the work performed in the care and management of patients as they participate within clinical trials. 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. 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, 2019 and 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. 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 (See note 28-Impact of new accounting policies in the consolidated financial statements). 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. 37 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. 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.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 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. The information included in the discussion and analysis below provides details on the information for the years ended December 31, 2019 and December 31, 2018. Information related to the year ended December 31, 2017 has not been included. It can be found in the company's filing of the form 20-F for the year ended December 31, 2018. 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, 2019, we employed approximately 14,650 employees, in 97 locations in 40 countries. During the year ended December 31, 2019 we derived approximately 31.8%, 58.5% and 9.7% 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 performance method based on the relationship between cost incurred and the total estimated costs 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. 41 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, 2019 we had unsatisfied performance obligations 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. A. Operating Results The following table sets forth, for the periods indicated, certain financial data as a percentage of revenue and the percentage change in these items compared to the prior comparable period. The trends illustrated in the following table may not be indicative of future results. Revenue Costs and expenses: Direct costs Selling, general and administrative Depreciation Amortization Income from operations (excluding restructuring) Restructuring Income from operations (including restructuring) Year Ended December 31, 2019 2018 2019 Percentage of Revenue Percentage Increase/(Decrease) 100.0% 100.0% 8.1 % 70.4% 12.0% 1.6% 0.6% 15.4% —% 15.4% 70.0% 12.6% 1.9% 0.6% 14.9% 0.5% 14.4% 8.6 % 3.4 % (9.8)% 3.9 % 12.3 % (100.0)% 16.1 % 42 Year ended December 31, 2019 compared to year ended December 31, 2018 Revenue (dollars in thousands) Revenue Year Ended December 31, Change 2019 2018 $ % 2,805,839 2,595,777 210,062 8.1% Revenue for the year increased by $210.1 million, or 8.1%, to $2,805.8 million, compared to $2,595.8 million for the year ended December 31, 2018. Revenue increased by 9.6% in constant currency or 8.4% in constant dollar organic. The increase in revenues can be explained by both continued organic growth and the additional revenues from the acquisitions of MMD on January 25, 2019, MeDiNova on May 23, 2019 and Symphony on September 24, 2019. Revenues from our top five customers were $1,055.3 million in the year ended December 31, 2019 compared to $1,024.1 million in the year ended December 31, 2018 or 37.6% and 39.5% respectively. The largest of these customers related to a strategic partnership with a large global pharmaceutical company. Revenue from this customer contributed 13.6% of revenue for the year ended December 31, 2018, compared to 12.5% of revenue for the year ended December 31, 2019. The second largest customer, also a large global pharmaceutical company, accounted for 10.2% of the Group's revenue for the year ended December 31, 2019. 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 $186.6 million in the year ended December 31, 2019, to $1,252.8 million, compared to $1,066.2 million for the year ended December 31, 2018. Revenue in Ireland during the year ended December 31, 2019 increased by 17.5% compared to an overall increase in group revenue of 8.1%. Revenue in Ireland is principally a function of our global contracting model (see note 19 - Business segment and geographical information in the consolidated financial statements). Revenue for Rest of Europe increased by $9.0 million or 2.4%, to $388.9 million, compared to $379.9 million for the year ended December 31, 2018, principally reflecting the acquisition of MeDiNova in May 2019. Revenue in the U.S. decreased by $2.5 million or 0.3%, to $892.5 million, compared to $895.0 million for the year ended December 31, 2018. Revenue in our Rest of World (‘Other’) region increased by $16.9 million or 6.6%, to $271.6 million, compared 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 (dollars in thousands) Direct costs % of revenue Year Ended December 31, 2019 2018 Change $ 1,974,135 $ 1,818,220 $ 155,915 70.4% 70.0% 8.6% Direct costs for the year increased by $155.9 million, or 8.6%, to $1,974.1 million, compared to $1,818.2 million for the year ended December 31, 2018. Direct costs consists primarily of investigator and other reimbursable costs, 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 year relates to increases in third party investigator and other reimbursable costs, an increase in direct project related costs and personnel related expenditure. 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 $54.3 million combined with an increase in other direct project related costs of $1.8 million, increases in laboratory costs of $0.5 million, partly offset by a decrease in travel related costs of $0.4 million. 43 Selling, general and administrative expenses (dollars in thousands) Year Ended December 31, 2019 2018 Change Selling, general and administrative expenses $ 336,748 $ 325,794 $ 10,954 % of revenue 12.0% 12.6% 3.4% Selling, general and administrative expenses for the year increased by $11.0 million, or 3.4%, to $336.7 million, compared 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 to 12.0% of revenue, compared to 12.6% of revenue for the year ended December 31, 2018. During the year, general overhead costs net of foreign exchange costs increased by $8.1 million, acquisition costs increased by $3.3 million, marketing fees increased by $1.1 million, facilities related costs increased by $0.3 million, professional fees decreased by $1.0 million and personnel related costs decreased by $0.8 million. Share based compensation expense recognized during the years ended December 31, 2019 and December 31, 2018 was $26.8 million and $31.6 million respectively (see note 10 - Equity incentive Schemes and Stock Compensation Charges in the consolidated financial statements). Depreciation and amortization (dollars in thousands) Depreciation % of revenue Amortization % of revenue Year Ended December 31, 2019 2018 Change $ $ 45,603 $ 50,565 $ (4,962) 1.6% 1.9% 15,947 $ 15,351 $ 0.6% 0.6% (9.8)% 596 3.9 % Depreciation expense for the year decreased by $5.0 million or 9.8%, to $45.6 million, compared 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 decreased to 1.6% of revenues, compared to 1.9% for the year ended December 31, 2018. Amortization expense for the year increased by $0.6 million or 3.9%, to $15.9 million, compared 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 increase in amortization expense for the year reflects the amortization of newly acquired intangibles arising on the acquisition of MMD, MeDiNova and Symphony. These increases were partly offset by the completion of amortization on other assets. As a percentage of revenue, the amortization expense remained constant year on year at 0.6% of revenue. Restructuring costs (dollars in thousands) Restructuring % of revenue Year Ended December 31, 2019 — $ —% $ 2018 Change 12,490 $ (12,490) 0.5% (100.0)% 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. There was no restructuring charge during the year ended December 31, 2019 (see note 14 - Restructuring and other items to the consolidated financial statements). 44 Income from operations (dollars in thousands) Income from operations (incl. restructuring) % of revenue Income from operations (excl. restructuring) % of revenue Year Ended December 31, 2019 433,406 15.4% 433,406 15.4% $ $ $ $ 2018 Change 373,357 14.4% 385,847 $ $ 14.9% 60,049 16.1% 47,559 12.3% As a result of the above, income from operations increased by $60.0 million, or 16.1%, to $433.4 million, compared to $373.4 million ($385.8 million, excluding restructuring and other charges) for the year ended December 31, 2018. As a percentage of revenue, income from operations increased to 15.4% of revenues compared to 14.4% (14.9% excluding restructuring) of revenues for year ended December 31, 2018. Income from operations in Ireland increased by 22.2% (16.8% excluding restructuring) to $314.3 million, compared to $257.1 million ($269.2 million excluding restructuring) for the year ended December 31, 2018. Income from operations in Ireland and other geographic regions are reflective of the Company’s global transfer pricing model and the centralization of intragroup financing activities in Ireland. Continued strategic investment in personnel and infrastructure together with on-going enhancement of operating processes and the successful leverage of support costs in 2019 has continued to result in a decrease of the proportion of the Group’s revenue used to support other Group entities and a corresponding increase in income from operations in Ireland during 2019. In the Rest of Europe region, income from operations increased by $1.7 million ($1.1 million excluding restructuring), to $38.0 million, compared to $36.3 million ($36.9 million excluding restructuring) for the year ended December 31, 2018. As a percentage of revenues, income from operations in the Rest of Europe region increased to 9.8%, compared to 9.6% (9.7% excluding restructuring) for the year ended December 31, 2018. In the U.S. region, income from operations increased by $1.7 million ($1.9 million excluding restructuring), or 2.9%, to $60.3 million compared to $58.6 million for the year ended December 31, 2018 . As a percentage of revenues, income from operations in the U.S. region increased to 6.8% compared to 6.5% (6.5% excluding restructuring) for the year ended December 31, 2018. In other regions, income from operations decreased by $0.6 million ($0.6 million excluding restructuring), to $20.9 million, compared to $21.4 million ($21.4 million excluding restructuring) for the year ended December 31, 2018. As a percentage of revenues, income from operations in the other regions decreased to 7.7%, compared to 8.4% (8.4% excluding restructuring) for the year ended December 31, 2018. Interest income and expense (dollars in thousands) Interest income Interest expense Year Ended December 31, 2019 6,859 2018 4,759 (13,276) (13,502) Change $ 2,100 226 % 44.1 % (1.7)% Interest expense decreased to $13.3 million compared to $13.5 million for the year ended December 31, 2018. No amounts were drawn down on the revolving credit facility during the year ended December 31, 2019 or the year ended December 31, 2018. Interest income for the year ended December 31, 2019 increased to $6.9 million, compared to $4.8 million for the year ended December 31, 2018. 45 Income tax expense (dollars in thousands) Income tax expense Effective income tax rate Year Ended December 31, 2019 51,133 12.0% 2018 41,958 11.5% Change $ % 9,175 21.9% Provision for income taxes for the period increased to $51.1 million compared to $42.0 million for the year ended December 31, 2018. The Company’s effective tax rate for the year ended December 31, 2019 was 12% compared to 11.5% for the year ended December 31, 2018. The Company’s effective tax rate is principally a function of the distribution of pre-tax profits in the territories in which it operates. Net income per Ordinary Share attributable to the Group Basic net income per ordinary share attributable to the Group 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. Basic and diluted net income per ordinary share attributable to the Group includes the adjustment to reflect the accretion of the noncontrolling interest in MeDiNova to its redemption value. This adjustment to reflect changes in the redemption amount of the noncontrolling interest has been excluded from net income when calculating adjusted net income per ordinary share attributable to the Group (non-GAAP). See below section on non-GAAP financial measures. The reconciliation between net income attributable to the Group per the Statement of Operating Income and the net income used to calculate net income per ordinary share attributable to the Group is as follows: Year ended December 31, 2019 December 31, 2018 December 31, 2017 $ in thousands Net income attributable to the Group 373,986 322,656 281,488 Noncontrolling interest adjustment to redemption amount Net income attributable to the Group (including NCI redemption adjustment) (5,048) — — 368,938 322,656 281,488 The net income per Ordinary Share attributable to the Group and adjusted net income per Ordinary Share attributable to the Group reflecting the noncontrolling interest adjustment to redemption amount is as follows: December 31, 2019 December 31, 2018 December 31, 2017 Year ended Net income per Ordinary Share attributable to the Group (including NCI redemption adjustment): Basic (GAAP) Diluted (GAAP) Adjusted net income per Ordinary Share attributable to the Group (excluding NCI redemption adjustment): Adjusted basic (non-GAAP) Adjusted diluted (non-GAAP) 5.96 5.89 5.96 5.89 5.20 5.13 5.20 5.13 6.85 6.79 6.94 6.88 46 Non-GAAP Financial Measure We consider this non-GAAP financial measure to be a useful supplemental measure of our operating performance. A non- GAAP financial measure is a measure of historical or future financial performance, financial position or cash flows that excludes or includes amounts that are not so excluded from or included in the most directly comparable measure calculated and presented in accordance with GAAP. Described below is the non-GAAP financial measure used by management to evaluate our operating performance and that we consider more useful to investors. The non-GAAP financial measures we present in this Form 20-F may not be comparable to those presented by other companies due to the fact that not all companies use the same definitions. In Item 5, we have presented Net income per Ordinary Share attributable to the Group (GAAP) and Adjusted Net income per Ordinary Share attributable to the Group (non-GAAP). We have provided a reconciliation between the non-GAAP financial measure and its closest comparable GAAP measure being the Net income per Ordinary Share attributable to the Group. The reconciliation reflects one reconciling item for the adjustment of the MeDiNova noncontrolling interest balance to its redemption value. We believe providing the Adjusted Net income per Ordinary Share attributable to the Group (non-GAAP) provides better insight into the performance of the Company and enhances comparability with previous financial performance of the Company. The noncontrolling interest in MeDiNova is a non-recurring item which is expected to be concluded in the second quarter of the year ending December 31, 2020. In order to facilitate a clear understanding of our financial performance, you should examine this measure in conjunction with Net income per Ordinary Share attributable to the Group as presented in our Form 20-F. B. 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. Cash and cash equivalents and net borrowings Balance December 31, 2018 Drawn down/ (repaid) Net cash inflow/ (outflow) Other non- cash adjustments Effect of exchange rates Balance December 31, 2019 $ in thousands Cash and cash equivalents 395,851 Available for sale investments Private placement notes 59,910 (349,264) 106,497 — — — 125,108 — (650) 520,309 (12,028) — 113,080 1,746 (376) 1,370 — (650) 49,628 (349,640) 220,297 The Company’s cash and available for sale investments at December 31, 2019 amounted to $569.9 million compared with cash and available for sale investments of $455.8 million at December 31, 2018. The Company’s cash and short term investment balances at December 31, 2019 comprised cash and cash equivalents $520.3 million and short-term investments $49.6 million. 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. 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 bears interest at LIBOR plus a margin. We continue to monitor the phasing out of LIBOR which is 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. No amounts were drawn at December 31, 2019, or at December 31, 2018, in respect of the Revolving Credit Facility. Amounts available to the Group under the facility at December 31, 2019 and at December 31, 2018 were $150.0 million. 47 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 ASC 815 'Derivatives and Hedging'. The cash proceeds, representing the realized gain on the interest rate hedge, were received on maturity in November 2015. 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 continue to 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. In connection with the purchase consideration to acquire a 100% interest in Symphony Clinical Research in September 2019, the company has recognized a contingent liability of $2.5 million at December 31, 2019. This amount is payable to the vendors and is contingent upon Symphony Clinical Research attaining certain financial targets up to March 31, 2020. It is expected that this contingent consideration will be finalized during the second quarter of 2020. In connection with the acquisition of 60% of the share capital in MeDiNova in May 2019, the vendors have a right to sell the remaining shares exclusively to ICON during 2020. The cash consideration payable to redeem this 40% noncontrolling interest is linked to the earnings performance of MeDiNova for the twelve month period ending 31 March 2020. We expect to redeem this noncontrolling interest for cash consideration of approximately $43.9 million in 2020. Based on our current operating plan, the Group believes it has adequate liquidity to satisfy the cash needs for at least the next 12 months. The Group has historically funded its operations, including acquisitions, mainly with its working capital, cash flow generated from operations and debt facilities as appropriate. Cash flows Net cash from operating activities Net cash provided by operating activities was $412.5 million for the year ended December 31, 2019 compared with net cash provided by operating activities of $268.6 million for the year ended December 31, 2018. 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 in the previous financial year, 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 recorded as accrued to investigators and others in respect of reimbursable expenses were $142.6 million at December 31, 2019 and $85.6 million at December 31, 2018 (see note 7 - Other liabilities in the consolidated financial statements). 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 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, 2019 was 72 days compared to 67 days at December 31, 2018. This reflects both extended credit terms provided to a number of key accounts and the timing of cash collections. 48 Net cash used in investing activities Net cash used in investing activities was $162.0 million for the year ended December 31, 2019 compared to net cash used in investing activities of $37.3 million for the year ended December 31, 2018. Net cash used in investing activities the year ended December 31, 2019 was largely attributable to cash outflows on the acquisitions of MMD of $42.2 million on January 25, 2019, cash outflows on the acquisition of MeDiNova on May 23, 2019 of $54.1 million and cash outflows on the acquisition of Symphony on September 24, 2019 of $35.0 million. These were offset in part by cash acquired of $11.7 million. During the year, capital expenditure of $50.6 million, was made mainly related to investment in facilities and IT infrastructure. In addition, $21.7 million was generated by the sale of short term investments, $9.6 million was used for the purchase of short term investments and $3.9 million was used for the purchase of investments in equity. In December 2018, net cash used in investing activities of $37.3 million 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. Capital expenditure comprised mainly of expenditure on global infrastructure and information technology systems to support the Company’s growth. Net cash used in financing activities Net cash outflow from financing activities amounted to $125.4 million for the year ended December 31, 2019 compared with net cash outflow from financing activities of $113.0 million for the year ended December 31, 2018. Cash outflows in respect of financing activities includes consideration paid by the Company for share buybacks pursuant to the Company’s share repurchase program totaling $146.9 million in the year ended December 31, 2019 compared to $129.0 million in the year ended December 31, 2018 (see note 12 - Share Capital in the consolidated financial statements). Net cash outflow As a result of these cash flows, cash and cash equivalents increased by $124.5 million for the year ended December 31, 2019 compared to an increase of $113.0 million for the year ended December 31, 2018. Research and development, patents and licenses ICON plays a critical role in new drug development processes by undertaking activities in each of the different stages of the drug development process. Clinical trials result in an advancement in the field of medical science as they establish the safety and efficacy of new drugs thus resolving scientific uncertainty. As one of a number of world leaders in clinical research and commercialization, ICON is a trusted partner for pharmaceutical and medical device companies in helping them to accelerate the development of drugs and devices that save lives and improve the quality of life. ICON's role in ensuring that the trial design is scientifically valid is a crucial part of the design and involves scientists, medical doctors and biostatisticians. ICON works with the sponsors in designing the conduct of the clinical research trial. ICON's role in Ireland of conducting clinical trials is an integral part of the research and development process leading ultimately to a decision as to whether or not each drug is safe for human consumption, has the desired effect on targeted diseases and the best means of delivering that drug to the patient. Trend information Other than as disclosed elsewhere in this annual report, we are not aware of any trends, uncertainties, demands, or commitments or events since December 31, 2019 that are reasonably likely to have a material adverse effect on our revenues, income, profitability, liquidity or capital resources, or that would cause the reported financial information in this annual report to be not necessarily indicative of future operating results or financial conditions. A. Off-balance sheet arrangements Not applicable. 49 B.

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. In the 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, 2019 and December 31, 2018 therefore reflect application of ASC 606. ICON adopted the standard using the cumulative effect transition method. 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. 50 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. 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 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, 2019 Leases The Company adopted ASC 842 'Leases' (ASC 842), with a date of initial application of January 1, 2019. The lease accounting policy applied in preparation of the results for the twelve months ended December 31, 2019 therefore reflect application of ASC 842. ICON adopted the standard using the cumulative-effect adjustment approach. Under this transition method, ICON has applied the new standard as at the date of initial application (i.e. January 1, 2019), without restatement of comparative period amounts. The cumulative effect of applying the new standard is recorded as an adjustment to the opening consolidated balance sheet as at the date of initial application (see note 28 - Impact of change in accounting policies for further details). The comparative information has not been adjusted and therefore the results for the twelve months ended December 31, 2018 continue to be reported under ASC 840 'Leases'. The new standard requires lessees to recognize the rights and obligations resulting from virtually all leases on the balance sheet as right-of-use (ROU) assets with corresponding lease liabilities. The most significant impact of application of the new standard for ICON relates to the recognition of right-of-use assets and lease liabilities on the Consolidated Balance Sheet for operating leases for certain property, vehicles and equipment. Prior to application of ASC 842, costs in respect of operating leases were charged to the Consolidated Statements of Operations on a straight-line basis over the lease term. A lease liability and right-of-use asset of $106.5 million have been recorded on the Consolidated Balance Sheet as at January 1, 2019 (see note 28 - Impact of change in accounting policies for further details). The net operating cost of leases recorded in the year ended December 31, 2019 is $33.0 million (see note 22 - Operating leases for further details). Pursuant to certain practical expedients available as part of adopting ASC 842, ICON has not reassessed; whether existing or expired contracts are or contain leases, the classification of existing or expired leases, or whether unamortized initial direct costs meet the new definition of initial direct costs under ASC 842. Additionally, ICON has elected to use hindsight in determining the lease term and in assessing impairment of ROU assets, if any. ICON determines if an arrangement is a lease at inception. Finance leases, if any, are depreciated on the same basis as property, plant and equipment. At December 31, 2019 and December 31, 2018, the Group did not account for any leases as finance leases. Operating leases are included in operating right-of-use assets, other liabilities and non-current operating lease liabilities on our Consolidated Balance Sheet with the lease charge recognized on a straight-line basis over the lease term. ROU assets and lease liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date or date of transition. Our lease terms may also include options to extend or terminate. ICON actively reviews options to extend or terminate leases and adjusts the ROU asset and lease liability when it is reasonably certain the option will be exercised. The ROU asset is adjusted for any prepayments made at the date of commencement and any initial direct costs incurred. As most of ICON's leases do not provide an implicit rate, the discount rate used is based on the rate of traded corporate bonds available at the commencement date adjusted for country risk, liquidity and lease term. 51 Leasehold improvements are amortized over the shorter of the depreciable lives of the corresponding fixed assets or the lease term including any applicable renewals. Certain property leases include variable lease payments resulting from periodic rent increases based on an index which are recognized as incurred on the Consolidated Statements of Operations. ICON accounts for lease and non-lease components separately with lease components flowing through the Consolidated Balance Sheet and non-lease components expensed directly to the Consolidated Statements of Operations. Other We have reviewed the FASB issued Accounting Standards Update (ASU) accounting pronouncements and interpretations thereof that have effective dates during the periods reported. The following relevant ASUs have also been adopted in 2019: In August 2017, the FASB issued ASU 2017-12, 'Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities (Topic 815)'. The updated guidance expands an entity’s ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. Entities will apply the amendments to cash flow and net investment hedge relationships that exist on the date of adoption using a modified retrospective approach. The presentation and disclosure requirements apply prospectively. This ASU was effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2018. The adoption of this ASU did not have a significant 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 was effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2018. The adoption of this ASU did not have a significant impact on the financial statements. 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, with early adoption permitted. The company early adopted this ASU from January 1, 2018. The adoption of this ASU did not have a significant impact on the financial statements. In July 2018, the FASB issued ASU 2018-09, 'Codification Improvements'. This amendment makes changes to a variety of topics to clarify, correct errors in, or make minor improvements to the Accounting Standards Codification (ASC). The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments do not require transition guidance and will be effective upon issuance of ASU 2018-09. The amendments effective upon issuance did not have a material impact on the Company's consolidated financial statements. A majority of the amendments do have transition guidance with effective dates for annual periods beginning after December 15, 2018. The adoption of this ASU did not have a significant impact on the financial statements. In June 2018, the FASB issued ASU 2018-07, which expands the scope of ASC 718 'Compensation—Stock Compensation' (ASC 718) to include share based payment transactions for acquiring goods and services from nonemployees and more closely aligns the accounting for employee and nonemployee share-based payments. This ASU was effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2018. The adoption of this ASU did not 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 was effective for all entities for annual and interim periods in fiscal years beginning after December 15, 2018. The adoption of this ASU did not have a significant impact on the financial statements. In February 2018, the FASB issued ASU 2018-03, which provided technical corrections and improvements to Accounting Standards Update No. 2016-01, 'Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities'. The amendments clarify certain aspects of the guidance issued in update 2016-01. The ASU was effective for public business entities for fiscal years beginning after December 15, 2017. The adoption of this ASU did not have a significant impact on the financial statements. 52 Impact of new accounting pronouncements which will be adopted during fiscal year ended December 31, 2020 In June 2016, the FASB issued ASU 2016-13 'Measurement of Credit Losses on Financial Instruments (Topic 326)', 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 update provides guidance on the measurement of credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The amendment replaces the current incurred loss impairment approach with a methodology to reflect expected credit losses and requires consideration of a broader range of reasonable and supportable information to explain credit loss estimates. The updated guidance is to be applied on a modified retrospective approach and is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 for public business entities that are SEC filers. The adoption of Topic 326 is not expected to have a significant impact on the financial statements. In August 2018, the FASB issued ASU No. 2018-15, 'Intangibles - Goodwill and Other - Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (Topic 350)'. The amendments in the update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The ASU is effective for public businesses, that are SEC filers for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years and is to be applied either retrospectively or prospectively to all implementation costs incurred after the adoption date. The adoption of ASU 2018-15 is not expected to have a significant impact on the financial statements. In August 2018, the FASB issued ASU 2018-13, 'Fair Value Measurement - Disclosure Framework (Topic 820)'. The updated guidance requires entities to disclose changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. Amendments in this guidance also require disclosure of transfers into and out of Level 3 of the fair value hierarchy, purchases and issues of Level 3 assets and liabilities, and clarify that the measurement uncertainty disclosure is about the uncertainty in measurement as of the reporting date. The guidance removes requirements to disclose the amounts and reasons for transfers between Level 1 and Level 2, policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurements. The updated guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for any removed or modified disclosures. The adoption of ASU 2018-13 is not expected to have a significant impact on the financial statements. In November 2019, the FASB issued ASU 2019-08 'Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606)'. The amendments in this update require that an entity measure and classify share based payment awards granted to a customer by applying the guidance in Topic 718. The amount recorded as a reduction of the transaction price is required to be measured on the basis of the grant-date fair value of the share-based payment award in accordance with Topic 718. The grant date is the date at which a grantor (supplier) and a grantee (customer) reach a mutual understanding of the key terms and conditions of a share-based payment award. The classification and subsequent measurement of the award are subject to the guidance in Topic 718 unless the share-based payment award is subsequently modified and the grantee is no longer a customer. The amendments in this update are effective for public business entities in fiscal years beginning after December 15, 2019. The adoption of ASU 2019-08 is not expected to have a significant impact on the financial statements. Impact of other new accounting pronouncements In August 2018, the FASB issued ASU 2018-14, 'Compensation - Retirement Benefits - Defined Benefit Plans (Topic 715)'. The updated guidance requires additional disclosures of weighted-average interest crediting rates for cash balance plans and an explanation of the reasons for significant gains and losses related to changes in the benefit obligation. Amendments in the guidance also clarify the requirement to disclose the projected benefit obligation (PBO) and fair value of plan assets for plans with PBOs in excess of plan assets. The same disclosure is needed for the accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. The guidance removes certain previous disclosure requirements no longer considered cost beneficial. The amendments are effective for fiscal years ending after December 15, 2020, with early adoption permitted. The Company is currently assessing the impact of adopting the updated provisions. In December 2019, the FASB issued ASU 2019-12 'Simplifying the Accounting for Income Taxes (Topic 740)'. The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The Company is currently assessing the impact of adopting the updated provisions. No other new accounting pronouncement issued or effective has had, or is expected to have, a material impact on the Company’s consolidated financial statements. Inflation We believe that the effects of inflation generally do not have a material adverse impact on our operations or financial conditions. 53 Item 6. Directors, Senior Management and Employees.

Compensation 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 equity incentive schemes. During 2019, 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: $335,490) annually. Mr. Rónán Murphy was appointed as Lead Independent Director with effect from January 1, 2019 and received 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 for 2019 ranging from 40% to 85% of salary based on group and individual performance. A total bonus of $1.2 million was awarded to the following individuals; Dr. Steve Cutler Chief Executive Officer ($0.9 million) and Mr. Brendan Brennan Chief Financial Officer ($0.3 million) to reflect their contribution to the performance of the Company during 2019. These amounts were approved by the Compensation and Organization Committee and will be paid during the year ended December 31, 2020. 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 equity award 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 median of comparable Irish companies and peer CRO companies. Contributions to this plan are recorded as an expense in the Consolidated Statement of Operations. 57 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).

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 nine 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 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 (10 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, 2019 the Board held five board meetings. All Directors allocated sufficient time to the Company during the year ended December 31, 2019 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 2020, it is anticipated that 4 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 to commence on the date that he/she 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. Rónán Murphy was appointed as Lead Independent Director with effect from that date. 62 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 during the year ended December 31, 2019 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 three independent Directors: Rónán Murphy (Chairperson), Professor Hugh Brady and Eugene McCague. Declan McKeon stepped down as Chairperson and Rónán Murphy assumed the position of Chairperson with effect from February 19, 2019. Declan McKeon stepped down as member of the Committee on July 22, 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 Rónán Murphy. Rónán Murphy stepped down as Chairperson of the Committee and Joan Garahy assumed the position of 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 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: Eugene McCague (Chairperson), Professor William Hall and Joan Garahy. Professor William Hall stepped down as Chairperson of the Committee and Eugene McCague assumed the position as Chairperson with effect from July 22, 2019. Declan McKeon, who served as a member of the Committee during 2019, stepped down as a member of the Committee on July 22, 2019. 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 Officers: Steve Cutler (Chairperson), Rónán Murphy and Brendan Brennan. On January 1, 2019, Declan McKeon stepped down as a member of the Execution Committee and Rónán Murphy joined the Committee. 63 Attendance at Board and Committee meetings Attendance at Board and Committee meetings by the Directors who held office during 2019 are set out as follows: Directors’ Attendance Table Director Ciaran Murray Dr. Steve Cutler Rónán Murphy (1) Prof. Hugh Brady (1) Dr. John Climax (1) Joan Garahy (1) Prof. William Hall (1) Prof. Dermot Kelleher (1) (5) Eugene McCague (1) (4) Declan McKeon (1) (2) (3) (4) Julie O'Neill (1) (6) Mary Pendergast (1) Board Audit Compensation and Organization Nominating and Governance Number of meetings attended / number of meetings eligible to attend as a Director 5/5 5/5 5/5 5/5 5/5 5/5 5/5 2/2 5/5 2/2 3/3 5/5 — — 4/4 4/4 — — — 4/4 2/2 — — — — 4/4 — — 4/4 4/4 — — — 4/4 — — — — — 5/5 4/5 — 3/3 2/2 — — (1) Independent Director as defined under NASDAQ Rule 5605(a)(2).

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 30 2019, the Company approved the 2019 Consultants and Directors Restricted Share Unit Plan (the “2019 Consultants RSU Plan”), which was effective as of May 16, 2019, pursuant to which the Compensation and Organization Committee of the Company’s Board of Directors may select any consultant, adviser or Non-Executive Director retained by the Company, or a Subsidiary to receive an award under the plan. 250,000 ordinary shares have been reserved for issuance under the 2019 Consultants RSU Plan. The awards are at par value and vest over a service period. Awards granted to Non-Executive Directors in May 2019 vest over twelve months. 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 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 0.4 million to 1.0 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 1.0 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 0.4 million 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. 68 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 0.4 million 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. Share options granted to Non-Executive Directors during 2018 vest over 12 months and expire eight years from the date of grant. Item 7. Major Shareholders and Related Party Transactions. A.

Memorandum and articles of association 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. 70 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. 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 EGMs. 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 their interest above or below 3% of the total issued share capital of the Company, they 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. 71 C. Material Contracts Not applicable. D. 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, South Sudan, the Central African Republic, Libya, Iraq, the Democratic People's Republic of Korea, Myanmar/Burma, Tunisia, Zimbabwe, Egypt, Venezuela, certain persons, entities and bodies in Syrian Arab Republic, the Republic of Guinea-Bissau, Nicaragua, Democratic Republic of Congo, Iran, Ukraine, associated with the Taliban in Afghanistan; associated with ISIL (Da’esh) and Al-Qaeda; associated with Turkey’s unauthorized drilling activities in the Eastern Mediterranean and certain known terrorists and terrorist groups and countries that harbor certain terrorist groups, without the prior permission of the Central Bank of Ireland. There are no restrictions under the Company’s Constitution or under Irish Law that limit the right of non-residents or foreign owners to hold the Company’s ordinary shares or vote at general meetings of the Company. E. 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%. 72 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”); 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 25%. 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. 73 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: • • • • • 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. 74 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; • 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/she made the settlement, or at the date of the gift or, if he/she is dead at the date of the gift, at the date of his/her 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 • €335,000 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 9, 2019. This threshold was €320,000 prior to October 9, 2019. 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. 75 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. 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. F. Dividends and paying agents Not applicable G. Statement by experts Not applicable H. 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 exhibits to such incorporated information that are not specifically incorporated by reference into such information). Requests for such copies should be directed to us at the following address: ICON plc, South County Business Park, Leopardstown, Dublin 18, Ireland, Attention: Erina Fox, telephone number: +353 1 2912000. I. Subsidiary Information Not applicable 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. 76 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 2019 Consultants and Directors Restricted Share Unit Plan, 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 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, 2019. The following significant exchange rates applied during the year: Euro:USD Pound Sterling:USD Average Rate Closing Rate 2019 1.1183 1.2735 2018 1.1846 1.3401 2019 1.1213 1.3257 2018 1.1467 1.2754 77 Interest Rate Risk 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 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 effective interest rate is reduced by the impact of 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 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%. The senior notes are due for repayment in December 2020. We regularly evaluate our debt arrangements, as well as market conditions, and during the year we will explore the opportunity to modify our existing arrangements or pursue additional financing arrangements that may result in the issuance of new debt securities by us or our affiliates. The sensitivity analysis below represents the hypothetical change in the net interest payable of a 1% movement in market interest rates.

Principal Accountant Fees and Services Our principal accountants for the years ended December 31, 2019 and December 31, 2018 were KPMG. The table below summarizes the fees for professional services rendered by KPMG for the audit of our annual financial statements for the years ended December 31, 2019 and December 31, 2018 and fees billed for other services rendered by KPMG.

At December 31, 2018 a total of 4,026,576 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 other undenominated capital as required under Irish Company law. 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. 81 Item 16F. Changes in Registrant's Certifying Accountant Not applicable.

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, 2019. 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, 2019 the Company's internal control over financial reporting was effective. There have been no changes in the Company's internal control over financial reporting during 2019 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, 2019, included herein, and has issued an audit report on the effectiveness of our internal control over financial reporting, which is included below. 84 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, 2019 and 2018, 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, 2019, 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, 2019 and 2018, and the results of its operations and its cash flows for each of the years in the three year period ended December 31, 2019, 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, 2019, 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 February 27, 2020 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 financial statements, the Company has changed its method of accounting for revenue recognition as of January 1, 2018 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. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgment. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Evaluation of progress towards completion and realizable contract value related to revenue recognition for clinical trial service contracts As described in Note 2(c) to the consolidated financial statements, clinical trial service revenue is recognized over time, using an input measure, being total project costs (inclusive of third party costs). The Company recognized revenue of US $2,805.8 million for the year ended 31 December 2019 (2018: US$2,595.8 million). A significant portion of this revenue relates to clinical trial service revenue. Clinical trial service revenue is recognized using project costs incurred to date relative to total estimated costs to complete to measure progress towards satisfying the Company’s performance obligation. 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 the change order. Furthermore, the transaction price is determined by adjusting the contract or change order value to reflect a realizable contract value. We identified the evaluation of progress towards completion and realizable contract value related to revenue recognition for clinical trial services contracts as a critical audit matter. Complex and subjective auditor judgment was required to 85 evaluate the Company’s estimate regarding the direct costs and costs that will be incurred by third parties to complete the contracts, based on historical experience and estimated realizable contract values on clinical trial service contracts. The primary procedures we performed to address this critical audit matter included the following: We tested certain internal controls over the Company’s revenue recognition for the clinical trial service contracts process. These included controls over the development of the estimated direct costs and costs that will be incurred by third parties to complete the contracts and estimated realizable contract values. We tested the estimated costs to complete and the realizable contract values for a sample of clinical trial service contracts, by evaluating: • • • Actual direct costs incurred, both during the year and life-to-date, to assess the consistency with the estimated direct costs for that time period. We compared actual direct costs incurred to source timesheet data and hourly rates to underlying contractual terms; Third-party costs incurred, to assess the consistency with the estimated third-party costs for that time period. We compared third-party costs incurred to invoices received; Findings from interviews with operational personnel of the Company to evaluate progress to date, the estimate of remaining costs to be incurred and factors impacting the amount of time and cost to complete the sampled contracts, including the assessment of the nature and complexity of the work to be performed; • Correspondence, if any, between the Company and the customer for the sampled contracts as part of our evaluation of contract progress; • Changes to estimated costs, including the amount and timing of the changes; and • The basis for the realizable contract value assumptions and challenging these assumptions. We confirmed contract terms with customers and assessed the realizable contract values by comparing the assumptions to underlying records, including final contract invoices received. We also evaluated the Company’s ability to accurately estimate costs to complete and realizable contract values, by comparing historical estimates developed at contract inception to actual results for a sample of contracts.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, 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, 2019 and 2018, 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, 2019, and the related notes (collectively, the “consolidated financial statements”), and our report dated February 27, 2020 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.

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, 2019 we had approximately 14,650 employees, in 97 locations in 40 countries. During the year ended December 31, 2019, we derived approximately 31.8%, 58.5% and 9.7% of our 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. ASC 606 - Revenue from Contracts with Customers (years ended December 31, 2019 and December 31, 2018) ICON adopted ASC 606 'Revenue from Contracts with Customers' (ASC 606) standard using the cumulative effect transition method for the first time in the year ended December 31, 2018. Under this transition method, ICON 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) was recorded as an adjustment to the opening balance of equity at the date of initial application. The comparative information, for the year ended December 31, 2017 is not adjusted and therefore continues to be reported under ASC 605 ‘Revenue Recognition’ (ASC 605) and therefore in accordance with previous accounting policies. 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. 94 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 incurred (inclusive of third party costs) at each reporting period as a percentage of total forecast project costs. 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 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. Commissions 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 on application of ASC 606 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. ASC 605 - Revenue recognition (year ended December 31, 2017) 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. 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. 95 Contract staffing revenue is recognized on a fee-for-service basis, over the time the related service is performed. 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. 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. (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. 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. 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 $8,088,451, $6,516,637 and $6,744,333 for the years ended December 31, 2019, December 31, 2018 and December 31, 2017 respectively. (g) Foreign currencies and translation of subsidiaries The Company's financial statements are prepared in United States dollars. Transactions in currencies other than the functional currency of the Company are recorded at the rate ruling at the date of the transaction. Monetary assets and liabilities denominated in currencies other than the functional currency of the Company are translated into the functional currency 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 Statements of Operations for the years ended December 31, 2019, December 31, 2018 and December 31, 2017 were as follows: Amounts charged/(credited) $ 590 $ (3,876) $ 7,760 2019 Year ended December 31, 2018 (in thousands) 2017 96 The financial statements of subsidiaries with other functional currencies are translated at period end rates for the Consolidated Balance Sheets and average rates for the Consolidated Statements 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/unearned revenue, 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 Sheets 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. 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, 2019, 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. The Company allocates a share of net income to the noncontrolling interest holders based on percentage ownership. 97 ICON acquired a majority ownership interest in MeDiNova. Included in the purchase agreement are put and call option arrangements with the noncontrolling interest holders that require (put option) or enable (call option) ICON to purchase the remaining minority ownership at a future date. The option is accounted for as temporary equity, which is presented separately as redeemable noncontrolling interest on the Consolidated Balance Sheet. This classification reflects the assessment that the instruments are contingently redeemable in accordance with ASC 480-10-S99 'Distinguishing Liabilities from Equity'. Redeemable noncontrolling interests are accreted to their redemption value over the period from the date of issuance to the first date on which the option is exercisable. The change in the option's redemption value is recorded against retained earnings. In a computation of earnings per share, the accretion of redeemable noncontrolling interests to their redemption value is a reduction of net income attributable to the Group. Basic and diluted net income per ordinary share attributable to the Group includes the adjustment to reflect the accretion of the noncontrolling interest to its redemption value. (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 'Intangibles - Goodwill and Other: Simplifying the test for goodwill impairment' 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, 2019, December 31, 2018 and December 31, 2017. (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 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. 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, 2019 meet the definition of equity securities without readily determinable fair values. Effective from January 1, 2018, the Company concluded that the interests held at December 31, 2018 and December 31, 2019 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. Where the Company enters into an agreement to sell certain portfolios of its accounts receivable balances, the sale is accounted for in accordance with ASC Topic 860 'Transfers and Servicing' (ASC 860). Agreements which result in true sales of the transferred receivables, as defined in ASC 860, which occur when receivables are transferred without recourse to ICON, are excluded from amounts reported in the Consolidated Balance Sheet. Cash proceeds received from such sales are included in operating cash flows. The associated finance costs are presented as interest expense. 98 (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, 2019 the carrying value of inventory, included within prepayments and other current assets on the Consolidated Balance Sheet, was $3.2 million (2018: $2.3 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) Leases The Company adopted ASC 842 'Leases' (ASC 842), with a date of initial application of January 1, 2019. The lease accounting policy applied in preparation of the results for the year ended December 31, 2019 therefore reflect application of ASC 842. ICON adopted the standard using the cumulative-effect adjustment approach. Under this transition method, ICON has applied the new standard as at the date of initial application (i.e. January 1, 2019), without restatement of comparative period amounts. The cumulative effect of applying the new standard is recorded as an adjustment to the opening consolidated balance sheet as at the date of initial application (see note 24 - Impact of new accounting pronouncements for further details). The comparative information has not been adjusted and therefore continues to be reported under ASC 840 'Leases' (ASC 840). The new standard requires lessees to recognize the rights and obligations resulting from virtually all leases on the Consolidated Balance Sheet as right-of-use (ROU) assets with corresponding lease liabilities. The most significant impact of application of the new standard for ICON relates to the recognition of right-of-use assets and lease liabilities on the Consolidated Balance Sheet for operating leases for certain property, vehicles and equipment. Prior to application of ASC 842, costs in respect of operating leases were charged to the Consolidated Statements of Operations on a straight-line basis over the lease term. Pursuant to certain practical expedients available as part of adopting ASC 842, ICON has not reassessed; whether existing or expired contracts are or contain leases, the classification of existing or expired leases, or whether unamortized initial direct costs meet the new definition of initial direct costs under ASC 842. Additionally, ICON has elected to use hindsight in determining the lease term and in assessing impairment of ROU assets, if any. ICON determines if an arrangement is a lease at inception. Finance leases, if any, are depreciated on the same basis as property, plant and equipment. At December 31, 2019 and December 31, 2018, the Group did not account for any leases as finance leases. Operating leases are included in operating right-of-use assets, other liabilities and non-current operating lease liabilities on our Consolidated Balance Sheet with the lease charge recognized on a straight-line basis over the lease term. ROU assets and lease liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date or date of transition. Our lease terms may also include options to extend or terminate. ICON actively reviews options to extend or terminate leases and adjusts the ROU asset and lease liability when it is reasonably certain the option will be exercised. The ROU asset is adjusted for any prepayments made at the date of commencement and any initial direct costs incurred. As most of ICON's leases do not provide an implicit rate, the discount rate used is based on the rate of traded corporate bonds available at the commencement date adjusted for country risk, liquidity and lease term. Leasehold improvements are amortized over the shorter of the depreciable lives of the corresponding fixed assets or the lease term including any applicable renewals. Certain property leases include variable lease payments resulting from periodic rent increases based on an index which are recognized as incurred on the Consolidated Statements of Operations. ICON accounts for lease and non-lease components separately with lease components flowing through the Consolidated Balance Sheet and non-lease components expensed directly to the Consolidated Statements of Operations. 99 In some cases, ICON enters into sublease agreements and becomes both a lessee and a lessor for the same underlying asset. Although subleases are accounted for separately from the lease they relate to, subleases are accounted for in the same way as other leases. The lease accounting policy applied in preparation of the results for the year ended December 31, 2018 reflected the application of ASC 840. Under this accounting policy, 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 for 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 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 'Defined Benefit Plans – Pension'. These plans are presented in accordance with the requirements of ASC 715-60 'Defined Benefit Plans – Other Postretirement'. (v) Net income per ordinary share Basic net income per ordinary share attributable to the Group 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. Basic and diluted net income per ordinary share attributable to the Group includes the adjustment to reflect the accretion of the noncontrolling interest in MeDiNova to its redemption value (see note 26 - Net income per ordinary share). 100 (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 ASC 718 'Compensation – Stock Compensation'. Share-based compensation expense for equity- 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, 2019 or December 31, 2018. We use derivative financial instruments to reduce exposure to fluctuations in foreign exchange rates. During the years ended December 31, 2018 and December 31, 2019 we entered into forward currency contracts in respect of identified exposure arising from euro payments. All contracts expired during the year in which the contract was entered into. 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 forecast 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 Consolidated 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. 101 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. 3. Investments (a) Available for sale investments Available for sale investments at start of year Purchases Sales and maturities Interest on short term investments Realized gain on sale of short term investments Unrealized capital gain/(loss) – investments December 31, 2019 December 31, 2018 (in thousands) $59,910 9,603 (21,686) 1,065 55 681 $77,589 80,956 (99,865) 1,329 56 (155) Available for sale investments at end of year $49,628 $59,910 The Company classifies its investment in short term investments as available for sale. Short term investments comprise highly liquid investments with maturities of greater than three months and minimum "A-" rated fixed and floating rate securities. Short term investments at December 31, 2019 have an average maturity of 0.65 years compared to 1.22 years at December 31, 2018. The investments are reported at fair value with unrealized gains or losses reported in a separate component of shareholders' equity. Any differences between the cost and fair value of investments are represented by accrued interest and unrealized gains/ losses. The fair value of short term investments are represented by level 1 fair value measurements – quoted prices in active markets for identical assets. The following table represents our available for sale short term investments by major security type as of December 31, 2019: US government debt securities Corporate securities Term deposits Total (U.S.$ in millions) Maturity by period Cost Total 14.91 32.57 1.91 $49.39 Unrealized gains / (losses) Fair Value Total Less than 1 year (U.S.$ in millions) 0.16 0.08 — $0.24 15.07 32.65 1.91 $49.63 6.01 29.64 0.68 $36.33 1 to 5 years 9.06 3.01 1.23 $13.30 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 at 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 $10.1 million had been advanced under the terms of the subscription agreements at December 31, 2019 (December 31, 2018: $6.2 million). The Company determined that the interests in the funds meet the definition of equity securities without readily determinable fair values. Effective from January 1, 2018, the Company concluded that the interests held at December 31, 2019 qualify for the NAV practical expedient in ASC 820 'Fair value measurements and disclosures'. There was a decrease in fair value of $0.8 million (December 31, 2018: increase in fair value of $0.8 million) recognized in net income during the year bringing the carrying value of the subscriptions to $10.1 million at December 31, 2019 (December 31, 2018: $7.0 million). The Company had committed to future investments of $22.5 million in respect of these funds. 102 4. Goodwill Opening goodwill Current year acquisitions Prior period acquisition (note 4 (d)) Foreign exchange movement Closing goodwill December 31, 2019 December 31, 2018 (in thousands) $ 756,260 $ 769,058 126,932 — (22) — 1,048 (13,846) $ 883,170 $ 756,260 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 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, 2019 during the year ended December 31, 2019 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. Acquisitions (a) Symphony On September 24, 2019 a subsidiary of the Company, ICON Clinical Research LLC, acquired a 100% interest in Symphony. Symphony is a leading provider of at-home trial services and site support services. The acquisition of Symphony further enhances our site & patient services offering. The acquisition resulted in the recognition of goodwill of $23.1 million. The acquisition of Symphony has been accounted for as a business combination in accordance with ASC 805 'Business Combinations'. The Company has made a provisional assessment of the fair value of assets acquired and liabilities assumed as at that date. Cash & cash equivalents Property, plant and equipment Operating right of use assets Goodwill * Customer relationships ** Order backlog ** Accounts receivable Unbilled revenue Prepayments and other current assets Other receivables Accounts payable Unearned revenue Other liabilities Current lease liabilities Non-current lease liabilities Net assets acquired Cash outflows Contingent consideration payable Working capital adjustment payable Total consideration 103 September 24, 2019 (in thousands) 3,292 $ 564 820 23,072 7,975 2,140 3,579 186 181 6 (799) (1,446) (933) (289) (531) $ $ $ 37,817 34,976 2,500 341 37,817 *Goodwill represents the acquisition of an established workforce and the capability to provide at-home trial services and site support solutions. The full amount of the goodwill recognized is expected to be deductible for income tax purposes. **The Company has made an estimate of separate intangible assets acquired, being customer relationships and order book assets. The fair value of Symphony’s intangible assets has been measured provisionally, pending receipt of a final independent valuation. This assessment will be finalized within 12 months of the date of acquisition. The contingent consideration is based on revenue targets set for the Company to the period ending March 31, 2020. The fair value of the contingent consideration on acquisition was $2.5 million based on an income approach. The payment of contingent consideration will be in the range of zero to a maximum of $2.5 million. Due to the short term nature of the contingent consideration, no discounting has been applied. There has been no movement in the value of the contingent consideration from the date of acquisition to the year ended December 31, 2019. As the fair value measure is based on significant inputs that are not observable in the market, the contingent consideration meets the definition of a level 3 financial instrument under ASC 820. The inputs that are not observable in the market are the expected revenue of the Company to the period ending March 31, 2020 and the probability of achievement of this revenue target by the Company. A positive or negative movement of these inputs by 10% would not result in a material change to the contingent consideration balance at December 31, 2019. If new information obtained within one year of the date of acquisition about facts and circumstances that existed at the date of acquisition identifies adjustments to the above amounts, or any additional amounts that existed at the date of acquisition, then the accounting for the acquisition will be revised. Since September 24, 2019, Symphony has earned revenue of $4.5 million and net income of $1.0 million in the year ended December 31, 2019. The proforma effect of the Symphony acquisition if completed on January 1, 2018 would have resulted in revenue, net income and earnings per share for the fiscal years ending December 31, 2019 and December 31, 2018 as follows: Revenue Net income Basic earnings per share Diluted earnings per share b) MeDiNova Year Ended 2019 2018 (in thousands) $ 2,818,280 $ 2,609,233 324,671 $ 6.00 $ 5.93 $ 376,636 $ 6.90 $ 6.84 $ On May 23, 2019 a subsidiary of the Company, ICON Clinical Research (U.K.) Limited acquired a 60% majority shareholding in MeDiNova, a site network with research sites in key markets in Europe and Africa.

The overall investment strategy is that approximately 20% of investments are in world equities, corporate bonds, high yield bonds, multi-asset credit fund and senior secured loans, respectively. There is no self-investment in employer related assets. The expected long-term rate of return on assets at December 31, 2019 of 4.0% 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 (including 50% high yield bonds) Equities Secured Loans and Multi Asset Credit Cash Expected long- term return per annum 3.4% 5.8% 3.6% 2.1% The long-term expected rate of return on cash is determined by reference to traditional corporate bond rates at the latest Balance Sheet date. The long-term expected returns on traditional corporate and government bonds are determined by reference to corporate bond yields and gilt yields respectively at the Balance Sheet date. The long-term expected returns on equities is based on the rate of return on government bonds with an allowance for out-performance. The long-term expected return on high yield bonds, secured loans and multi asset credit is based on the return on traditional corporate bonds with an allowance for out- performance. The underlying asset split of the fund is shown below. Asset Category Corporate Bonds (including 50% high yield bonds) Equities Secured Loans and Multi Asset Credit Gilts Cash December 31, 2019 40% 21% 39% —% —% 100% December 31, 2018 25% —% —% 71% 4% 100% Applying the above expected long term rates of return to the asset distribution at December 31, 2019, gives rise to an expected overall rate of return of scheme assets of approximately 4.0% per annum.

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. Aptiv Solutions pension plan On May 7, 2014 the Company acquired 100% of the common stock of Aptiv Solutions ("Aptiv"). The acquisition of Aptiv was accounted for as a business combination in accordance with ASC 805 'Business Combinations'. The Company has a defined benefit plan covering its employees in Switzerland as mandated by the Swiss government. Benefits are based on the employee's years of service and compensation. Benefits are paid directly by the Company when they become due, in conformity with the funding requirements of applicable government regulations. The plan is managed externally and the related pension costs and liabilities are assessed in accordance with the advice of a professionally qualified actuary. Plan assets at December 31, 2019 and December 31, 2018 consist of units held in independently administered funds.

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 0.4 million to 1.0 million and to extend the date for options to be granted under the 2008 Option Plans. 116 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 1.0 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 0.4 million 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 0.4 million 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.

Options exercisable represent options which have vested at December 31, 2019. From the date of grant, substantially all options vest over a five year period at 20% per annum. 118 Fair value of Stock Options Assumptions The weighted average fair value of options granted during the years ended December 31, 2019, December 31, 2018 and December 31, 2017 was calculated using the Black-Scholes option pricing model. The weighted average fair values and assumptions were as follows: Weighted average fair value Assumptions: Expected volatility Dividend yield Risk-free interest rate Expected life Year Ended December 31, 2019 December 31, 2018 December 31, 2017 $ 43.43 $ 36.84 $ 25.06 30% —% 30% —% 29% —% 2.55% 5.0 years 2.76% 5.0 years 1.93% 5.0 years 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 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. On April 30 2019, the Company approved the 2019 Consultants and Directors Restricted Share Unit Plan (the “2019 Consultants RSU Plan”), which was effective as of May 16, 2019, pursuant to which the Compensation and Organization Committee of the Company’s Board of Directors may select any consultant, adviser or non-executive Director retained by the Company, or a Subsidiary to receive an award under the plan. 250,000 ordinary shares have been reserved for issuance under the 2019 Consultants RSU Plan. The awards are at par value and vest over a service period. Awards granted to non-executive directors in May 2019 vest over twelve months. The Company has awarded RSUs and PSUs to certain key individuals of the Group. The following table summarizes RSU and PSU activity for the year ended December 31, 2019: PSU Outstanding Number of Shares PSU Weighted Average Grant Date Fair Value PSU Weighted Average Remaining Contractual Life RSU Outstanding Number of Shares RSU Weighted Average Grant Date Fair Value RSU Weighted Average Remaining Contractual Life Outstanding at December 31, 2018 251,053 $ 85.95 0.96 534,677 $ 89.50 1.22 Granted Shares vested Forfeited 60,182 $ 140.13 (118,611) $ (16,635) $ 71.45 91.94 160,237 $ (238,960) $ (66,054) $ 138.33 69.19 107.03 Outstanding at December 31, 2019 175,989 $ 110.79 1.04 389,900 $ 119.07 1.43 The fair value of RSUs vested for the year ended December 31, 2019 totaled $16.5 million (2018: $18.8 million). The fair value of PSUs vested for the year ended December 31, 2019 totaled $8.5 million (2018: $14.7 million). 119 The PSUs vest based on service and specified EPS targets over the period 2017 – 2019, 2018 – 2020 and 2019 – 2021. Depending on the actual amount of EPS from 2017 to 2021, up to an additional 75,615 PSUs may also be granted. Non-cash stock compensation expense Income from operations for the year ended December 31, 2019 is stated after charging $26.8 million in respect of non- cash stock compensation expense. Non-cash stock compensation expense has been allocated as follows: Direct costs Selling, general and administrative Total compensation costs December 31, 2019 Year ended December 31, 2018 (in thousands) December 31, 2017 $ $ 14,777 $ 17,408 $ 12,042 14,186 18,020 12,553 26,819 $ 31,594 $ 30,573 Total non-cash stock compensation expense not yet recognized at December 31, 2019 amounted to $42.4 million. The weighted average period over which this is expected to be recognized is 2.18 years. The income tax expense for the year ended December 31, 2019 reflects a net income tax benefit of $8.2 million in connection with stock compensation (including excess tax benefits) and the total tax benefit in connection with stock options exercised during 2019 was $1.9 million. 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 (excluding excess tax benefits) and the total tax benefit realized in connection with stock options exercised during 2017 was $3.2 million. 11.

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 $44,000 for the year ended December 31, 2019 (December 31, 2018: $47,000). As at December 31, 2019 the Company had $3.1 million (December 31, 2018: $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, 2019, 329,870 options were exercised by employees at an average exercise price of $65.54 per share for total proceeds of $21.6 million. During the year ended December 31, 2019, 237,119 ordinary shares were issued in respect of certain RSUs and 118,611 ordinary shares were issued in respect of PSUs previously awarded by the Company. 120 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, 273,742 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, 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. (a) Share Repurchase Program 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. 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 program for $400 million). A resolution was passed at the Company’s Annual General Meeting (“AGM”) on July 22, 2016, which authorized the Directors to purchase (buyback) up to 10% of the outstanding shares in the Company. This authorization was renewed at the Company's AGM on each of July 25, 2017, July 24, 2018 and July 23, 2019. On October 3, 2016, the Company commenced a share buyback program of up to $400 million. The share buyback program was completed during the year ended December 31, 2018 with a total of 4,026,576 ordinary shares redeemed for a total consideration of $372.1 million. On January 8, 2019, the Company commenced a further share buyback program of up to 1.0 million ordinary shares which was completed during the year ended December 31, 2019. These shares were redeemed by the Company for a total consideration of $141.6 million. On October 22, 2019, the Company commenced a further share buyback program. At December 31, 2019, 35,100 ordinary shares were redeemed by the Company for a total consideration of $5.3 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 other undenominated capital as required under Irish Company law. 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. 13. Income Taxes The Company's United States and Irish based subsidiaries file income tax returns in the United States and Ireland respectively. Other foreign subsidiaries are taxed separately under the laws of their respective countries. The components of income before income tax expense are as follows: Ireland United States Other December 31, 2019 Year ended December 31, 2018 (in thousands) December 31, 2017 $ 323,726 $ 243,988 $ 218,306 21,073 82,190 27,499 93,127 28,426 81,325 Income before income tax expense $ 426,989 $ 364,614 $ 328,057 121 The components of income tax expense are as follows: Income tax expense: Current tax expense: Ireland United States Other December 31, 2019 Year ended December 31, 2018 (in thousands) December 31, 2017 $ 35,955 $ 28,042 $ 20,084 5,073 11,642 2,885 9,379 5,792 9,964 Total current tax expense 52,670 40,306 35,840 Deferred tax (benefit)/expense: Ireland United States Other 2,833 (3,502) (868) 1,054 875 (277) 261 8,980 1,488 Total deferred tax (benefit)/expense (1,537) 1,652 10,729 Income tax expense allocated to continuing operations 51,133 41,958 46,569 Impact on other comprehensive income of the income tax consequence of : Currency impact on long term funding Fair value of cash flow hedge 25 — 119 (148) 973 148 Total $ 51,158 $ 41,929 $ 47,690 Ireland's statutory income tax rate is 12.5%.

The income tax expense recognized in respect of deemed repatriation of historic earnings of non-U.S. subsidiaries owned by our U.S. subsidiaries was $7.7 million. The income tax expense recognized in respect of the change in the US federal income tax rate from 35% to 21% was $0.5 million (included in “Effects of change in tax rates” above). 122 The tax effects of temporary differences that give rise to significant portions of deferred tax assets and deferred tax liabilities are presented below: Deferred tax liabilities: Property, plant and equipment Right-of-use-asset Goodwill Intangible assets Other Total deferred tax liabilities recognized Deferred tax assets: Operating loss and tax credits carryforwards Property, plant and equipment Lease Liabilities Accrued expenses and payments on account Stock compensation Deferred compensation Unearned revenue Other Total deferred tax assets Valuation allowance for deferred tax assets Deferred tax assets recognized Overall net deferred tax asset December 31, 2019 December 31, 2018 (in thousands) $ 1,102 $ 11,838 27,590 11,805 6,284 981 — 25,149 9,397 5,703 58,619 41,230 37,865 5,257 11,754 26,380 5,009 2,744 3,933 604 93,546 29,995 4,893 — 24,599 6,490 2,197 5,681 2 73,857 (27,721) (27,263) 65,825 46,594 $ 7,206 $ 5,364 At December 31, 2019 the Company has recognized a deferred tax asset of $11.8 million and a deferred tax liability of $11.8 million in respect of operating lease arrangements under which future tax deductions are attributable to the lease liability. At December 31, 2019 Ireland subsidiaries had tax credit carryforwards for income tax purposes that may be carried forward indefinitely, available for offset against future tax liabilities, if any, of $6.5 million. At December 31, 2019 U.S. subsidiaries had U.S. federal and state net operating loss ("NOL") carryforwards of approximately $22.2 million and $45.0 million, respectively. These NOLs are available for offset against future taxable income and the expiry dates are shown in the table below. Of the $22.2 million U.S. federal NOLs, approximately $7.0 million is available for offset against future U.S. federal taxable income in 2020. The subsidiary's ability to use the remaining U.S. federal and state NOL carryforwards is limited on an annual basis due to change of ownership in 2014, 2017, and 2019, as defined by Section 382 of the Internal Revenue Code of 1986, as amended. Of the U.S. federal NOLs, $20.2 million are limited by Section 382. Of the $20.2 million of losses, the amounts are available as follows: $10.0 million for the years 2020 - 2021, $9.8 million in 2022-2026, $0.4 million for the years 2027 – 2036. As at December 31, 2019, U.S subsidiaries also had disallowed interest carryforwards of $29.3 million that can be carried forward indefinitely. These carryforwards 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, 2019 other than those in the U.S. and Ireland, we had operating loss carryforwards for income tax purposes that may be carried forward indefinitely, available to offset against future taxable income, if any, of approximately $40.1 million. In addition at December 31, 2019 those subsidiaries had tax credit carryforwards for income tax purposes that may be carried forward indefinitely, available to offset against future tax liabilities, if any, of $5.1 million. At December 31, 2019 those subsidiaries also had additional operating loss carryforwards of $16.2 million which are due to expire between 2020 and 2026 and operating loss carryforwards of $19.1 million which are due to expire between 2027 and 2036. 123 The expected expiry dates of these US losses are as follows: 2022-2035 2037 Indefinite Federal NOL's (in thousands) State NOL's 18,866 $ 44,986 1,921 1,363 — 49 22,150 $ 45,035 $ $ In addition, US subsidiaries have alternative minimum tax credit carryforwards of approximately $0.3 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 general business tax credit carryforwards of approximately $1.0 million that are available to offset future U.S. federal and state income taxes. The general business tax credits are non-refundable and are due to expire between the years 2026-2038. The valuation allowance at December 31, 2019 was approximately $27.7 million. The valuation allowance for deferred tax assets as of December 31, 2018 and December 31, 2017 was $27.3 million and $22.4 million respectively. The net change in the total valuation allowance was an increase of $0.4 million during 2019 and an increase of $4.8 million during 2018. Of the total increase of $0.4 million in 2019, $Nil resulted in current year income tax benefit and $0.4 million was recognized in Other Comprehensive Income. Of the total increase of $4.8 million in 2018, $5.6 million resulted in a current year income tax expense, and $0.8 million was recognized in Other Comprehensive Income. The valuation allowances at December 31, 2019 and December 31, 2018 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 2018, the Company recognized a valuation allowance of $6.2 million in respect of disallowed interest carryforwards 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. During 2019, $3.4 million of this valuation allowance was released following a refinancing of the group's US subsidiaries. The Company has recognized a deferred tax liability of $5.4 million (2018: $4.9 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 considered 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 Ireland 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: Unrecognized tax benefits at start of year Increase related to prior year tax positions Decrease related to prior year tax positions Increase related to current year tax positions Settlements Lapse of statute of limitations December 31, 2019 December 31, 2018 (in thousands) December 31, 2017 $ 21,433 $ 23,720 $ 26,620 — — 1,588 (347) (2,518) 2,084 (2,915) 3,065 (182) (4,339) — (3,050) 4,765 (2,523) (2,092) Unrecognized tax benefits at end of year $ 20,156 $ 21,433 $ 23,720 The relevant statute of limitations for unrecognized tax benefits totaling $3.8 million could potentially expire during 2020. 124 Included in the balance of total unrecognized tax benefits at December 31, 2019 were potential benefits of $20.2 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, 2018 and December 31, 2017 included potential benefits which, if recognized, would affect the effective rate of income tax from continuing operations of $21.4 million and $23.7 million respectively. Interest and penalties recognized during the year ended December 31, 2019 amounted to $Nil (2018: net expense of $1.3 million, 2017: net expense of $0.9 million) and are included within the income tax expense. Total accrued interest and penalties as of December 31, 2019 and December 31, 2018 were $1.1 million and $1.1 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, 2016, December 31, 2017, December 31, 2018 and December 31, 2019. In Ireland, tax periods open to audit include the years ended December 31, 2015, December 31, 2016, December 31, 2017, December 31, 2018 and December 31, 2019. During such audits, local tax authorities may challenge the positions taken by us in our tax returns. 14.

Commitments and Contingencies Litigation The Company is not party to any litigation or other legal proceedings that the Company believes could reasonably be expected to have a material adverse effect on the Company's business, results of operations and financial condition. Operating Leases The Company has several non-cancelable operating leases, primarily for facilities, that expire over the next twelve years. These leases generally contain renewal options and require the Company to pay all executory costs such as maintenance and insurance. The Company transitioned to ASC 842 'Leases' (ASC 842) with effect from January 1, 2019 under the cumulative effect adjustment approach (see note 28 - Impact of changes in accounting policies). Under this transition method, ASC 842 is applied from January 1, 2019 without restatement of comparative period amounts. Results for the year ended December 31, 2018 and December 31, 2017 are therefore presented under the previous leasing accounting principles, ASC 840 'Leases' (ASC 840). Pursuant to ASC 840, the Company recognized $40.3 million and $44.0 million in rental expense, including rates, for the years ended December 31, 2018 and December 31, 2017 respectively. Future minimum rental commitments for operating leases with non-cancelable terms in excess of one year as of December 31, 2018 were as follows: 2019 2020 2021 2022 2023 Thereafter Total Minimum rental payments (in thousands) 32,634 26,839 21,306 15,781 10,829 19,194 126,583 See note 22 - Operating leases for rental expense and future minimum rental commitments pursuant to ASC 842 for the year ended and as of December 31, 2019. 126 16.

Revenue for the year ended December 31, 2017 reflects gross revenue (including reimbursable costs) under ASC 605. Our customers have similar profiles and economic characteristics, and therefore have similar degrees of risk and growth opportunities. 17. Accounts receivable, unbilled revenue (contract assets) and unearned revenue or payments on account (contract liabilities) Accounts receivable and unbilled revenue are as follows: Billed services (accounts receivable) Unbilled services (unbilled revenue) Accounts receivable and unbilled revenue Allowance for doubtful accounts (note 18) December 31, 2019 December 31, 2018 (in thousands) $ 535,088 $ 423,680 422,769 957,857 (7,380) 362,926 786,606 (8,889) Accounts receivable and unbilled revenue, net $ 950,477 $ 777,717 Unbilled services and unearned revenue or payments on account (contract assets and liabilities) were as follows: (in thousands, except percentages) December 31, 2019 December 31, 2018 $ Change % Change Unbilled services (unbilled revenue) Unearned revenue (payments on account) Net balance $ $ 422,769 $ 362,926 $ 59,843 (366,988) (274,468) (92,520) 16.5% 33.7% 55,781 $ 88,458 $ (32,677) 36.9% 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 revenue 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 or billed in advance of the revenue being earned. 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. As there is no contractual right of set-off between unbilled services (contract assets) and unearned revenue (contract liabilities), each are separately presented gross on the Consolidated Balance Sheet. 127 The most significant impact of application of ASC 606 was 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, 2019 and December 31, 2018 were $142.6 million and $85.6 million (see note 7 - Other liabilities). Unbilled services as at December 31, 2019 increased by $59.8 million as compared to December 31, 2018. Unearned revenue increased by $92.5 million over the same period resulting in a decrease of $32.7 million in the net balance of unbilled services and unearned revenue or payments on account between December 31, 2018 and December 31, 2019. 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 $0.4 million for the twelve months ended December 31, 2019. As of December 31, 2019 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 48% of the unrealized performance obligation over the next twelve months, with the remainder recognized thereafter over the duration of the customer contracts. 18. Provision for Doubtful Debts The Company does business with most major international pharmaceutical companies. Provision for doubtful debts at December 31, 2019 and December 31, 2018 comprises: Opening provision Amounts used during the year Amounts provided during the year Amounts released during the year Foreign exchange Closing provision December 31, 2019 December 31, 2018 (in thousands) $ 8,889 $ — 1,691 (3,226) 26 8,930 (995) 3,083 (2,355) 226 $ 7,380 $ 8,889 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, the (‘CODM’) in accordance with ASC 280 'Segment Reporting'. The Company determined that the CODM was comprised of the Chief Executive Officer and the Chief Financial Officer. 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 our global contracting model and the Group’s transfer pricing model. 128 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. The Company's areas of operation outside of Ireland include the United States, United Kingdom, Belgium, Bulgaria, France, Germany, Italy, Spain, Poland, Portugal, Czech Republic, Hungary, Israel, Latvia, Romania, Russia, Serbia, Sweden, The Netherlands, Turkey, Ukraine, Canada, Mexico, Argentina, Brazil, Chile, Colombia, Peru, India, China (including Hong Kong), Japan, Singapore, South Korea, The Philippines, Taiwan, Thailand, 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, 2019 and December 31, 2018 and for the years ended December 31, 2019, December 31, 2018 and December 31, 2017 is as follows: a) The distribution of revenue by geographical area was as follows: Ireland Rest of Europe U.S. Other Total Year ended December 31, 2019 December 31, 2018 December 31, 2017 (in thousands) $ 1,252,834 $ 1,066,200 $ 388,916 892,497 271,592 379,883 894,978 254,716 Restated* 944,130 355,552 881,829 220,810 $ 2,805,839 $ 2,595,777 $ 2,402,321 * 2017 restated to reflect gross revenue. b) The distribution of income from operations, including restructuring and other items, by geographical area was as follows: Ireland Rest of Europe U.S. Other Total December 31, 2019 Year ended December 31, 2018 (in thousands) December 31, 2017 $ 314,287 $ 257,089 $ 232,032 37,997 60,272 20,850 36,280 58,561 21,427 26,493 58,322 21,491 $ 433,406 $ 373,357 $ 338,338 129 c) The distribution of income from operations, excluding restructuring and other items, by geographical area was as follows: Ireland Rest of Europe U.S. Other Total December 31, 2019 Year ended December 31, 2018 (in thousands) December 31, 2017 $ 314,287 $ 269,196 $ 240,115 37,997 60,272 20,850 36,904 58,340 21,407 26,351 58,164 21,461 $ 433,406 $ 385,847 $ 346,091 d) The distribution of long-lived assets (including right-of-use assets (year ended December 31, 2019 only)), net, by geographical area was as follows: Ireland Rest of Europe U.S. Other Total December 31, 2019 December 31, 2018 (in thousands) $ 110,522 $ 106,206 41,970 72,578 44,994 9,807 25,535 17,121 $ 270,064 $ 158,669 e) The distribution of depreciation, amortization and reduction in carrying value of the right-of-use assets (year ended December 31, 2019 only) by geographical area was as follows: Ireland Rest of Europe U.S. Other Total f) The distribution of total assets by geographical area was as follows: Ireland Rest of Europe U.S. Other Total 130 December 31, 2019 Year ended December 31, 2018 (in thousands) December 31, 2017 $ 30,635 $ 34,721 $ 14,370 33,922 12,995 5,331 21,605 4,259 26,277 6,857 24,246 3,917 $ 91,922 $ 65,916 $ 61,297 Year Ended December 31, 2019 December 31, 2018 (in thousands) $ 1,323,181 $ 1,073,411 660,797 755,271 168,263 514,010 646,512 120,322 $ 2,907,512 $ 2,354,255 g) The distribution of capital expenditures (including right-of-use assets (year ended December 31, 2019 only)) by geographical area was as follows: Ireland Rest of Europe U.S. Other Total December 31, 2019 Year ended December 31, 2018 (in thousands) December 31, 2017 $ 32,526 $ 30,942 $ 13,971 18,638 15,010 2,590 9,311 5,554 24,468 2,819 11,027 6,403 $ 80,145 $ 48,397 $ 44,717 h) The following table sets forth the clients which represented 10% or more of the Company's revenue in each of the periods set out below.

During the year ended December 31, 2019, the Group did not incur any costs related to variable lease payments. The adoption of ASC 842 resulted in the recognition of operating right-of-use assets and lease liabilities of $106.5 million at January 1, 2019. Additional right-of-use assets obtained in exchange for lease obligations during the year ended December 31, 2019 totaled $29.5 million. The weighted average remaining lease term and weighted-average discount rate at December 31, 2019 were 5.19 years and 2.91%, respectively. 132 Future minimum lease payments under non-cancelable leases as of December 31, 2019 were as follows: 2020 2021 2022 2023 2024 Thereafter Total future minimum lease payments Lease imputed interest Total Minimum rental payments (in thousands) 28,320 25,315 19,433 14,053 8,839 17,264 113,224 (8,311) 104,913 $ $ Operating lease liabilities are presented as current and non-current. Operating lease liabilities of $28.3 million have been included in other liabilities as at December 31, 2019. 23. Debt – Senior Notes 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 these Senior Notes is fixed at 3.64% for the five year term. The 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 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 Consolidated Statements of Operations over the term of the Senior Notes (net against interest payable). 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, 2019. The Senior Notes have not been 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. We regularly evaluate our financing arrangements and related market conditions. We are evaluating the opportunity to extend or modify our existing arrangements or pursue additional financing arrangements that may result in the issuance of new debt securities by us or our affiliates. Cash and short-term investments were $569.9 million at December 31, 2019. 24. Impact of New Accounting Pronouncements Impact of new accounting pronouncements adopted during fiscal year ended December 31, 2019 Leases The Company adopted ASC 842 'Leases' (ASC 842) with a date of initial application of January 1, 2019. The lease accounting policy applied in preparation of the results for the twelve months ended December 31, 2019 therefore reflect application of ASC 842. ICON adopted the standard using the cumulative-effect adjustment approach. Under this transition method, ICON has applied the new standard as at the date of initial application (i.e. January 1, 2019), without restatement of comparative period amounts. The cumulative effect of applying the new standard is recorded as an adjustment to the opening Consolidated Balance Sheet as at the date of initial application (see note 28 - Impact of change in accounting policies). The comparative information has not been adjusted and therefore the results for the years ended December 31, 2018 and December 31, 2017 continue to be reported under ASC 840 'Leases' (ASC 840). The new standard requires lessees to recognize the rights and obligations resulting from virtually all leases on the balance sheet as right-of-use (ROU) assets with corresponding lease liabilities. 133 The most significant impact of application of the new standard for ICON relates to the recognition of ROU assets and lease liabilities on the Consolidated Balance Sheets for operating leases for certain property, vehicles and equipment. Prior to application of ASC 842, costs in respect of operating leases were charged to the Consolidated Statements of Operations on a straight-line basis over the lease term. A lease liability and ROU asset have been recorded on the Consolidated Balance Sheet as at January 1, 2019 of $106.5 million (see note 28 - Impact of change in accounting policies). The net operating cost of leases recorded in the year ended December 31, 2019 is $33.0 million (see note 22 - Operating leases). Pursuant to certain practical expedients available as part of adopting ASC 842, ICON has not reassessed; whether existing or expired contracts are or contain leases, the classification of existing or expired leases, or whether unamortized initial direct costs meet the new definition of initial direct costs under ASC 842. Additionally, ICON has elected to use hindsight in determining the lease term and in assessing impairment of ROU assets, if any. ICON determines if an arrangement is a lease at inception. Finance leases, if any, are depreciated on the same basis as property, plant and equipment. At December 31, 2019 and December 31, 2018, the Group did not account for any leases as finance leases. Operating leases are included in operating ROU assets, other liabilities and non-current operating lease liabilities on our Consolidated Balance Sheets with the lease charge recognized on a straight-line basis over the lease term. ROU assets and lease liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date or date of transition. Our lease terms may also include options to extend or terminate. ICON actively reviews options to extend or terminate leases and adjusts the ROU asset and lease liability when it is reasonably certain the option will be exercised. The ROU asset is adjusted for any prepayments made at the date of commencement and any initial direct costs incurred. As most of ICON's leases do not provide an implicit rate, the discount rate used is based on the rate of traded corporate bonds available at the commencement date adjusted for country risk, liquidity and lease term. Leasehold improvements are amortized over the shorter of the depreciable lives of the corresponding fixed assets or the lease term including any applicable renewals. Certain property leases include variable lease payments resulting from periodic rent increases based on an index which are recognized as incurred in the Consolidated Statements of Operations. ICON accounts for lease and non-lease components separately with lease components flowing through the Consolidated Balance Sheets and non-lease components expensed directly to the Consolidated Statements of Operations. Other We have reviewed the FASB issued Accounting Standards Update (ASU) accounting pronouncements and interpretations thereof that have effective dates during the periods reported. The following relevant ASUs have also been adopted in 2019: In August 2017, the FASB issued ASU 2017-12 'Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities (Topic 815)'. The updated guidance expands an entity’s ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. Entities will apply the amendments to cash flow and net investment hedge relationships that exist on the date of adoption using a modified retrospective approach. The presentation and disclosure requirements apply prospectively. This ASU was effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2018. The adoption of this ASU did not have a significant 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 was effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2018. The adoption of this ASU did not impact on the financial statements. 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, with early adoption permitted. The Company early adopted this ASU from 1 January 2018. The adoption of this ASU did not have a significant impact on the financial statements. 134 In July 2018, the FASB issued ASU 2018-09 'Codification Improvements'. This amendment makes changes to a variety of topics to clarify, correct errors in, or make minor improvements to the Accounting Standards Codification (ASC). The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments do not require transition guidance and will be effective upon issuance of ASU 2018-09. The amendments effective upon issuance did not have a material impact on the Company's consolidated financial statements. A majority of the amendments do have transition guidance with effective dates for annual periods beginning after December 15, 2018. The adoption of this ASU did not have a significant impact on the financial statements. In June 2018, the FASB issued ASU 2018-07, which expands the scope of ASC 718 'Compensation—Stock Compensation' (ASC 718) to include share based payment transactions for acquiring goods and services from nonemployees and more closely aligns the accounting for employee and nonemployee share-based payments. This ASU was effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2018. The adoption of this ASU did not 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 was effective for all entities for annual and interim periods in fiscal years beginning after December 15, 2018. The adoption of this ASU did not have a significant impact on the financial statements. In February 2018, the FASB issued ASU 2018-03, which provided technical corrections and improvements to ASU No. 2016-01 'Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities'. The amendments clarify certain aspects of the guidance issued in update 2016-01. The ASU was effective for public business entities for fiscal years beginning after December 15, 2017. The adoption of this ASU did not have a significant impact on the financial statements. Impact of new accounting pronouncements which will be adopted during fiscal year ended December 31, 2020 In June 2016, the FASB issued ASU 2016-13 'Measurement of Credit Losses on Financial Instruments (Topic 326)', 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 update provides guidance on the measurement of credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The amendment replaces the current incurred loss impairment approach with a methodology to reflect expected credit losses and requires consideration of a broader range of reasonable and supportable information to explain credit loss estimates. The updated guidance is to be applied on a modified retrospective approach and is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 for public business entities that are SEC filers. The adoption of Topic 326 is not expected to have a significant impact on the financial statements. In August 2018, the FASB issued ASU No. 2018-15 'Intangibles - Goodwill and Other - Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (Topic 350)'. The amendments in the update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The ASU is effective for public businesses, that are SEC filers for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years and is to be applied either retrospectively or prospectively to all implementation costs incurred after the adoption date. The adoption of ASU 2018-15 is not expected to have a significant impact on the financial statements. In August 2018, the FASB issued ASU 2018-13 'Fair Value Measurement - Disclosure Framework (Topic 820)'. The updated guidance requires entities to disclose changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. Amendments in this guidance also require disclosure of transfers into and out of Level 3 of the fair value hierarchy, purchases and issues of Level 3 assets and liabilities, and clarify that the measurement uncertainty disclosure is about the uncertainty in measurement as of the reporting date. The guidance removes requirements to disclose the amounts and reasons for transfers between Level 1 and Level 2, policy for timing between of transfers between levels, and the valuation processes for Level 3 fair value measurements. The updated guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for any removed or modified disclosures. The adoption of ASU 2018-13 is not expected to have a significant impact on the financial statements. 135 In November 2019, the FASB issued ASU 2019-08 'Codification Improvements—Share-Based Consideration Payable to a Customer'. The amendments in this update require that an entity measure and classify share-based payment awards granted to a customer by applying the guidance in ASC 718. The amount recorded as a reduction of the transaction price is required to be measured on the basis of the grant-date fair value of the share-based payment award in accordance with ASC 718. The grant date is the date at which a grantor (supplier) and a grantee (customer) reach a mutual understanding of the key terms and conditions of a share-based payment award. The classification and subsequent measurement of the award are subject to the guidance in ASC 718 unless the share-based payment award is subsequently modified and the grantee is no longer a customer. The amendments in this update are effective for public business entities in fiscal years beginning after December 15, 2019. The adoption of ASU 2019-08 is not expected to have a significant impact on the financial statements. Impact of other new accounting pronouncements In August 2018, the FASB issued ASU 2018-14 'Compensation - Retirement Benefits - Defined Benefit Plans (Topic 715)'. The updated guidance requires additional disclosures of weighted-average interest crediting rates for cash balance plans and an explanation of the reasons for significant gains and losses related to changes in the benefit obligation. Amendments in the guidance also clarify the requirement to disclose the projected benefit obligation (PBO) and fair value of plan assets for plans with PBOs in excess of plan assets. The same disclosure is needed for the accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. The guidance removes certain previous disclosure requirements no longer considered cost beneficial. The amendments are effective for fiscal years ending after December 15, 2020, with early adoption permitted. The Company is currently assessing the impact of adopting the updated provisions. In December 2019, the FASB issued ASU 2019-12 'Simplifying the Accounting for Income Taxes (Topic 740)'. The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The Company is currently assessing the impact of adopting the updated provisions. No other new accounting pronouncement issued or effective has had, or is expected to have, a material impact on the Company’s consolidated financial statements. 25. Related Parties Subsidiaries of the Company earned revenue of $95,000 (December 31, 2018: $633,000) 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. $36,000 was recorded as due from DS Biopharma Limited at December 31, 2019 (December 31, 2018: $338,000). Dr Ronan Lambe resigned as a Director of ICON plc on July 24, 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. The terms of the consultancy agreement expired on July 31, 2019. A charge of $151,360 was recorded during 2019 in respect of consultancy services provided by a company controlled by Mr. Lynch (December 31, 2018: $274,519). There were no amounts due to Mr. Lynch at December 31, 2019 (December 31, 2018: $64,000). 26. Net income per ordinary share Basic net income per ordinary share attributable to the Group 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. Basic and diluted net income per ordinary share attributable to the Group includes the adjustment to reflect the accretion of the noncontrolling interest in MeDiNova to its redemption value. 136  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 December 31, 2019 December 31, 2018 December 31, 2017 53,859,537 473,924 54,118,764 671,899 54,129,439 719,607 54,333,461 54,790,663 54,849,046 The reconciliation between net income attributable to the Group per the Statement of Operating Income and the net income used to calculate net income per ordinary share attributable to the Group is as follows: December 31, 2019 December 31, 2018 December 31, 2017 (in thousands) Net income attributable to the Group $ 373,986 322,656 $ 281,488 Noncontrolling interest adjustment to redemption amount Net income attributable to the Group (including NCI redemption adjustment) (5,048) — — 368,938 322,656 281,488 Net income per Ordinary Share attributable to the Group (including NCI redemption adjustment): Basic Diluted $ $ 6.85 $ 6.79 $ 5.96 $ 5.89 $ 5.20 5.13 December 31, 2019 December 31, 2018 December 31, 2017 27. Subsequent Events On January 22, 2020 a subsidiary of the Company, ICON Investments Limited acquired 100% of the equity share capital of MedPass International ("MedPass"). The initial consideration on acquisition is $39.2 million. The opening balance sheet remains under preparation and our initial estimate of the net assets of MedPass is approximately $9.2 million. MedPass is the leading European medical device CRO, regulatory and reimbursement consultancy, that specializes in medical device development and market access. The acquisition of MedPass further enhances ICON’s Medical Device and Diagnostic Research Services, through the addition of new regulatory and clinical capabilities in Europe. The integration of MedPass’s services brings noted expertise in complex class 3 medical devices, interventional cardiology and structural heart devices. On January 14, 2020, the Company announced the intention to buyback up to 1.0 million shares during 2020 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. The Company has evaluated subsequent events from the Balance Sheet date through February 27, 2020, 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. 137  28. Impact of change in accounting policies Leases The new leasing standard (ASU No. 2016-02 'Leases') was issued in February 2016. ASC 842 'Leases' (ASC 842) supersedes the requirements in ASC 840 'Leases' (ASC 840) and requires that lessees recognize rights and obligations from virtually all leases (other than leases that meet the definition of a short-term lease) on their Balance Sheets as right-of-use assets with corresponding lease liabilities. The ASU also provides additional guidance on how to classify leases and how to determine the lease term for accounting purposes. In July 2018, the FASB issued ASU No. 2018-11 'Leases (Topic 842): Targeted Improvements', which provides the option to adopt the standard retrospectively for each prior period presented, as initially set out in ASU No. 2016-02, or as of the adoption date with a cumulative-effect adjustment to the opening balance of retained earnings. ASC 842 became effective for ICON plc with effect from January 1, 2019. ICON adopted the new standard as of January 1, 2019 under the cumulative effect adjustment approach. Under this transition method, the new standard is applied from January 1, 2019 without restatement of comparative period amounts. Results for the years ended December 31, 2018 and December 31, 2017 are therefore presented under the previous leasing accounting principles, ASC 840. Operating lease liabilities and right-of- use assets have been recorded on the Consolidated Balance Sheets as at January 1, 2019 of $106.5 million. There is no impact of adopting ASC 842 on opening retained earnings at January 1, 2019. Revenue In the previous financial year, the Company adopted ASC 606 'Revenue from Contracts with Customers' (ASC 606) on 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 and the twelve months ended December 31, 2019. As ICON adopted the standard using the cumulative effect transition method, there was no restatement of comparative amounts. Therefore, the results for the year ended December 31, 2017 and previously reflect the provisions of ASC 605 'Revenue Recognition'. The most significant impact of application of the new standard was 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 Consolidated Statements 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 (exclusive of revenue from reimbursable expenses). This treatment is consistent with the adoption of ASC 606 from January 1, 2018 without restatement of comparatives. 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. 138 SIGNATURES The Registrant hereby certifies that it meets all of the requirements for filing on Form 20-F and that it has duly caused and authorized the undersigned to sign this annual report on its behalf.
