Recent Developments

Changes in Board composition and executive leadership transition

In February 2018, the Board approved the appointment of Mr. Ciaran Murray (Executive Chairman) as non-Executive Chairman of ICON plc with effect from May 12, 2018.

Acquisitions

On July 27, 2017, a subsidiary of the Company, ICON Clinical Research Limited acquired Mapi Development SAS ('Mapi') and its subsidiaries ("Mapi Group"). 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. Total cash outflows on acquisition were $145.8 million. The acquisition of Mapi Group strengthens ICON’s existing commercialization and outcomes research business adding significant commercialization presence, analytics, real world evidence generation and strategic regulatory services.

Share repurchase program

A resolution was passed at the Company’s Annual General Meeting (“AGM”) on July 22, 2016, which authorizes the Directors to purchase (buyback) up to 10% of the outstanding shares in the Company. On October 3, 2016, the Company commenced the share buyback program of up to $400 million. At December 31, 2017, a total of 3,018,414 ordinary shares were redeemed by the Company under the buyback program for a total consideration of $243.1 million. At March 31, 2018 a total of 3,363,526 ordinary shares were redeemed by the Company under this buyback program for a total consideration of $281.3 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 by Irish Company law.

New accounting pronouncements

The new revenue recognition standard (ASU No. 2014-09 ‘ Revenue from Contracts with Customers ’) was released in 2014 and becomes effective for ICON plc with effect from January 1, 2018. ICON has elected to adopt the new standard (ASC 606 - ' Revenue from Contracts with Customers ') under the cumulative effect transition method. Under this transition method, the new standard is applied from January 1, 2018 without restatement of comparative period amounts. The cumulative effect of initially applying the new standard is reflected as an adjustment to opening equity at the date of application ($48.1 million). Results for the three months ended March 2017 are therefore presented under the previous revenue recognition accounting principles, ASC 605. See ' Note 13-Impact of change in accounting policie s' for details of implications of adoption.

ASU 2016-16, ' Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory' was issued in October 2016 and requires entities to recognize at the transaction date the income tax consequences of intercompany asset transfers other than inventory. The effective date of the standard for public companies is for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The Company has adopted the modified retrospective approach, as required by the standard, in determining the cumulative impact in retained earnings at January 1, 2018. The cumulative impact recognized in retained earnings as at January 1, 2018 is nil and the new guidance has no impact on the financial statements as at March 31, 2018.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

March 31, 2018

1. Basis of Presentation

These condensed consolidated financial statements which have been prepared in accordance with United States Generally Accepted Accounting Principles (“US GAAP”) have not been audited. The condensed consolidated financial statements reflect all adjustments, which are, in the opinion of management, necessary to present a fair statement of the operating results and financial position for the periods presented. The preparation of the condensed consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect reported amounts and disclosures in the condensed consolidated financial statements. Actual results could differ from those estimates.

The condensed consolidated financial statements should be read in conjunction with the accounting policies and notes to the consolidated financial statements included in ICON’s Form 20-F for the year ended December 31, 2017 . Operating results for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the fiscal period ending December 31, 2018 .

2. Significant accounting policies

The Company adopted ASC 606, ‘ Revenue from Contracts with Customers’ , with a date of initial application of January 1, 2018. The revenue recognition accounting policy applied in preparation of the results for the three months ended March 31, 2018 therefore reflect application of ASC 606. ICON has elected to adopt the standard using the cumulative effect transition method. Under this transition method, ICON has applied the new standard as at the date of initial application (i.e. January 1, 2018), without restatement of comparative amounts. The cumulative effect of initially applying the new standard (to revenue, costs and tax) is recorded as an adjustment to the opening balance of equity at the date of initial application. See 'Note 13 - Impact of changes in accounting policies' for details. The comparative information has not been adjusted and therefore continues to be reported under ASC 605, ‘Revenue Recognition’ .

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

The most significant impact of application of the standard relates to our assessment of performance and percentage of completion in respect of our clinical trial service revenue. Prior to application of ASC 606, the revenue attributable to performance was determined based on both input and output methods of measurement. We have concluded that under the new standard, a clinical trial 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 trial. 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 therefore based on on an input measure being total project costs (inclusive of third party costs) at each reporting period

See 'Note 13 - Impact of changes in accounting policies' for details of the impact of application of the provisions of ASC 606 in the three months ended March 31, 2018 and in respect of the position at March 31, 2018.

3. Revenue

Revenue disaggregated by customer profile is as follows:

	Three months ended — March 31, 2018	March 31, 2017
	(in thousands)
Top client	$ 65,818	$ 104,682
Clients 2-5	164,301	90,265
Clients 6-10	98,539	55,341
Clients 11-25	117,271	70,364
Other	174,196	111,302
Total	$ 620,125	$ 431,954

4. Trade accounts receivable, unbilled services and payments on account

Trade accounts receivables and unbilled revenue are as follows:

	March 31, 2018		December 31, 2017
	(in thousands)
Contract assets:
Billed services (accounts receivable)	$ 403,893		$ 388,431
Unbilled services (unbilled revenue)	292,688		268,509
Trade accounts receivable and unbilled revenue	696,581		656,940
Allowance for doubtful accounts	(9,953	)	(8,930	)
Trade accounts receivable and unbilled revenue, net	$ 686,628		$ 648,010

Unbilled services and payments on account were as follows:

(in thousands, except percentages)	March 31, 2018		December 31, 2017		$ Change		% Change
Unbilled services (unbilled revenue)	$ 292,688		$ 268,509		$ 24,179		9.0 %
Unearned revenue (payments on account)	(332,353	)	(298,992	)	(33,361	)	11.2 %
Net balance	$ (39,665	)	$ (30,483	)	$ (9,182	)	30.1 %

Unbilled services as of March 31, 2018 , increased by $24.2 million as compared to December 31, 2017 . Adoption of ASC 606 as at January 1, 2018 resulted in a net reduction in unbilled revenue of $42 million . Unbilled services/revenue balances arise where invoicing or billing is based on the timing of agreed milestones related to service contracts for clinical research. Payments on account increased by $33.4 million over the same period resulting in a decrease of $9.2 million in the net balance of unbilled services and payments on account between December 31, 2017 and March 31, 2018 . These fluctuations are primarily due to timing of payments and invoicing related to the Group's clinical trial management contracts.

The bad debt expense recognized on the Group's receivables and unbilled services was de minimis for the three months ended March 31, 2018.

As of March 31, 2018 approximately $4.9 billion of revenue is expected to be recognized in the future in respect of unrealized performance obligations. The Company expects to recognize revenue on approximately 40% of the unrealized performance obligation over the next 12 months, with the remainder recognized thereafter over the duration of the customer contracts.

5. Goodwill

*Goodwill represents the acquisition of an established workforce with experience in preclinical through Phase IV support of clinical research and clinical trial services for biologics, drugs and devices. Goodwill related to the US portion of the business acquired is tax deductible. In finalizing the goodwill on acquisition of CRM in the twelve month period from acquisition, fair value adjustments were made which resulted in an increase to unbilled revenue ( $1.1 million ) and other liabilities ( $1.1 million ) and in a decrease to accounts receivable ( $0.3 million ) and accounts payable ( $0.5 million ). Customer list, order backlog and brand intangible asset values were also finalized.

	(in thousands)
Provision for income taxes	$ 10,650	$ 11,625

As at March 31, 2018 the Company maintains a $ 26.0 million liability ( December 31, 2017 : $ 26.1 million ) for unrecognized tax benefit, which is comprised of $ 23.6 million ( December 31, 2017 : $ 23.7 million ) related to items generating unrecognized tax benefits and $ 2.4 million ( December 31, 2017 : $ 2.4 million ) for interest and related penalties to such items.

The Company has analyzed the filing positions in all of the significant federal, state and foreign jurisdictions where it is required to file income tax returns, as well as open tax years in these jurisdictions. The only periods subject to examination by the major tax jurisdictions where the Company does business are 2013 through 2017 tax years. The Company does not believe that the outcome of any examination will have a material impact on its financial statements.

9. Net income per ordinary share

Basic net income per ordinary share has been computed by dividing net income available to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. Diluted net income per ordinary share is computed by adjusting the weighted average number of ordinary shares outstanding during the period for all potentially dilutive ordinary shares outstanding during the period and adjusting net income for any changes in income or loss that would result from the conversion of such potential ordinary shares. There is no difference in net income used for basic and diluted net income per ordinary share.

The reconciliation of the number of shares used in the computation of basic and diluted net income per ordinary share is as follows:

	Three Months Ended — March 31, 2018	March 31, 2017
Weighted average number of ordinary shares outstanding for basic net income per ordinary share	53,925,560	54,372,931
Effect of dilutive share options outstanding	1,060,230	998,895
Weighted average number of ordinary shares outstanding for diluted net income per ordinary share	54,985,790	55,371,826

10. Share-based Awards

Share Options

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

On February 14, 2017, both the 2008 Employee Plan and the 2008 Consultants Plan (together the “2008 Option Plans”) were amended and restated in order to increase the number of options that can be issued under the 2008 Consultants Plan from 400,000 to 1.0 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 400,000 ordinary shares. There is no individual limit under the 2008 Consultants Plan. No options may be granted under the 2008 Option Plans after February 14, 2027.

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

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

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

The following table summarizes option activity for the three months ended March 31, 2018 :

	Options Outstanding Number of Shares		Weighted Average Exercise Price	Weighted Average Grant Date Fair Value	Weighted Average Remaining Contractual Life
Outstanding at December 31, 2017	1,171,393		$ 56.02	$ 17.15
Granted	107,794		$ 115.11	$ 35.10
Exercised	(21,574	)	$ 33.53	$ 11.72
Forfeited	(5,855	)	$ 39.13	$ 12.74
Outstanding at March 31, 2018	1,251,758		$ 61.57	$ 18.81	4.95
Exercisable at March 31, 2018	594,051		$ 45.17	$ 14.54	3.73

The Company has outstanding options with fair values ranging from $ 8.53 to $ 35.10 per option or a weighted average fair value of $ 13.75 per option. The Company issues ordinary shares for all options exercised. The total amount of fully vested share options which remained outstanding at March 31, 2018 was 594,051 . Fully vested share options at March 31, 2018 have an average remaining contractual term of 3.73 years , an average exercise price of $ 45.17 and a total intrinsic value of $ 43.3 million . The total intrinsic value of options exercised during the three months ended March 31, 2018 was $ 1.8 million ( March 31, 2017 : $ 7.4 million ).

The following table summarizes the movement in non-vested share options for the three months ended March 31, 2018 :

Non-vested outstanding at December 31, 2017	Options Outstanding Number of Shares — 694,727		Weighted Average Exercise Price — $ 68.06	Weighted Average Grant Date Fair Value — $ 20.03
Granted	107,794		$ 115.11	$ 35.10
Vested	(142,109	)	$ 65.43	$ 19.31
Forfeited	(2,705	)	$ 56.58	$ 16.84
Non-vested outstanding at March 31, 2018	657,707		$ 76.38	$ 22.67

Fair value of Stock Options Assumptions

The weighted average fair value of options granted during the three months ended March 31, 2018 and March 31, 2017 was calculated using the Black-Scholes option pricing model. The weighted average grant date fair values and assumptions used were as follows:

	Three Months Ended — March 31, 2018	March 31, 2017
Weighted average grant date fair value	$ 35.10	$ 24.49
Assumptions:
Expected volatility	29 %	29 %
Dividend yield	— %	— %
Risk-free interest rate	2.63 %	2.05 %
Expected life	5 years	5 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 July 21, 2008, the Company adopted the 2008 Employees Restricted Share Unit Plan (the “2008 RSU Plan”) pursuant to which the Compensation and Organization Committee of the Company’s Board of Directors may select any employee, or any Director holding a salaried office or employment with the Company, or a Subsidiary to receive an award under the plan. An aggregate of 1.0 million ordinary shares have been reserved for issuance under the 2008 RSU Plan.

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

The Company has awarded RSUs and PSUs to certain key individuals of the Group. The following table summarizes RSU and PSU activity for the three months ended March 31, 2018 :

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

11. Share Capital

On October 3, 2016, the Company commenced a previously announced share buyback program of up to $ 400 million . The Company can acquire up to 10% of 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.

The buyback program gives a broker authority to acquire the Company’s ordinary shares from time to time on the open market in accordance with agreed terms and limitations. The acquisition of shares pursuant to the buyback program was effected by way of redemption and cancellation of the shares, in accordance with the Constitution of the Company.

During the three months ended March 31, 2018 345,112 ordinary shares were redeemed by the Company under this buyback program for a total consideration of $ 38.2 million . At March 31, 2018 a total of 3,363,526 ordinary shares were redeemed by the Company under this buyback program for a total consideration of $ 281.3 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 an other undenominated capital reserve as required under Irish Company Law.

12. Business Segment Information

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

The Company determines and presents operating segments based on the information that is provided to the CODM. The Company operates as one single business segment, which is the provision of outsourced development services on a global basis to the pharmaceutical, biotechnology and medical devices industries. There have been no changes to the basis of segmentation or the measurement basis for the segment results in the period.

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 is generally awarded projects based upon responses to requests for proposals received from companies in the pharmaceutical, biotechnology and medical device industries or work orders executed under our strategic partnership arrangements. Contracts with customers are generally entered into centrally, in most cases with ICON Clinical Research Limited (“ICON Ireland”), the Company’s principal operating subsidiary in Ireland. Revenues, which consist primarily of fees earned under these contracts, are allocated to individual entities within the Group, based on where the work is performed in accordance with the Company’s global transfer pricing model.

ICON Ireland acts as the group entrepreneur under the Company’s global transfer pricing model given its role in the development and management of the group, it’s ownership of key intellectual property and customer relationships, its key role in the mitigation of risks faced by the group and its responsibility for maintaining the Company’s global network. ICON Ireland enters into the majority of the Company’s customer contracts.

ICON Ireland remunerates other operating entities 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 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.

The geographic split of revenue disclosed for each region outside Ireland is the cost plus revenue attributable to these entities. The residual revenues of the Group, once each ICON entity has been paid its respective intercompany service fee, generally fall to be retained by ICON Ireland. As such revenues and income from operations in Ireland are a function of this global transfer pricing model and comprise revenues of the Group 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, France, Germany, Italy, Spain, The Netherlands, Sweden, Turkey, Poland, Czech Republic, Latvia, Russia, Ukraine, Hungary, Israel, Romania, Switzerland, Canada, Mexico, Brazil, Colombia, Argentina, Chile, Peru, India, China, South Korea, Japan, Thailand, Taiwan, Singapore, The Philippines, Australia, New Zealand, and South Africa.

13. Impact of change in accounting policies - revenue recognition

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 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) 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 therefore based on on an input measure being total project costs (inclusive of third party costs) at each reporting period

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

Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the unaudited Condensed Consolidated Financial Statements and accompanying notes included elsewhere herein and the Consolidated Financial Statements and related notes thereto included in our Form 20-F for the year ended December 31, 2017 . The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States.

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, 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 March 31, 2018 we employed approximately 13,380 employees, in 98 locations in 38 countries. During the three months ended March 31, 2018 we derived approximately 36.4% , 53.2% and 10.4% of our revenue in the United States, Europe and Rest of World respectively.

As the nature of our business involves the management of projects having a typical duration of a few weeks to several 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 clients from year to year.

Termination or delay in the performance of an individual contract may occur for various reasons, including, but not limited to, unexpected or undesired results, production problems resulting in shortages of the drug, adverse patient reactions to the drug, the client’s decision to de-emphasize a particular trial or inadequate patient enrolment 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 backlog consists of potential revenue yet to be earned from projects awarded by clients. At March 31, 2018 we had an unrealized performance obligation of approximately $4.9 billion (see Note 4). We believe that our remaining or unrealized performance obligation as of any date is not necessarily a meaningful predictor of future results, due to the potential for cancellation or delay of revenue.

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 of 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.

As we conduct operations on a global basis, our effective tax rate depends 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.

Results of Operations

Three Months Ended March 31, 2018 compared with Three Months Ended March 31, 2017

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.

	Three Months Ended — March 31, 2018	March 31, 2017	2018 to 2017
			Percentage
	Percentage of Revenue		Increase/ (Decrease)
Revenue	100.0 %	100.0 %	7.3	%
Costs and expenses:
Direct costs	43.8 %	43.3 %	8.5	%
Reimbursable expenses	25.6 %	25.3 %	8.7	%
Selling, general and administrative	13.1 %	14.1 %	(0.6	)%
Depreciation	1.9 %	1.7 %	18.3	%
Amortization	0.8 %	0.8 %	14.0	%
Income from operations	14.8 %	14.8 %	7.1	%

Revenue for the period increased by $42 million, or 7.3% , from $578.1 million for the three months ended March 31, 2017 to $620.1 million for the three months ended March 31, 2018 . Revenue increased by 4.3% in constant currency and decreased by 1.9% in constant dollar organic terms. The increase in revenues in the three months ended March 31, 2018 can be explained by both continued organic growth, and the additional revenues from the acquisition of Mapi on July 27, 2017. The Company changed its accounting policy for revenue recognition on the adoption of ASC 606, ‘ Revenue from Contracts with Customers’ , with a date of initial application of January 1, 2018 ( see Notes 2 and 13 ).

During the three months ended March 31, 2018 we derived approximately 36.4% , 53.2% and 10.4% of our revenue in the United States, Europe and Rest of World respectively. During the three months ended March 31, 2018 $230.1 million or 37.1% of our revenues were derived from our top 5 customers. The largest of these customers related to a Strategic Partnership with a large global pharmaceutical company. Revenue from this customer contributed 10.6% of revenue for the quarter. Revenue from our second largest customer contributed 10% for the quarter. Q1 2018 net revenue (reported under ASC 605 see Note 13) derived from our top 5 customers were $170.3 million or 36.8%, compared to $194.9 million or 45.1% of net revenues (ASC 605) derived from our top 5 customers during the three months ended March 31, 2017. Net revenue from our top customer (reported under ASC 605 see Note 13) was 11.9% at the end of March 31, 2018 and 24.2% of net revenue (ASC 605 - Note 13) in respect of the three months ended March 31, 2017. The addition of new customer accounts, particularly mid-tier pharma customers and biotech customers continues to result in a reduction in concentration of revenues from our top five customers.

Revenue in Ireland increased from $232.3 million for the three months ended March 31, 2017 to $235.1 million for the three months ended March 31, 2018 . Revenue in Ireland is principally a function of the Company’s global transfer pricing model ( see note 12 Business Segmental Information for further details ). Revenue in our Rest of Europe region increased from $72.6 million for the three months ended March 31, 2017 to $95.0 million for the three months ended March 31, 2018 , principally reflecting the acquisition of Mapi in July 2017. Revenue in our Rest of World region increased from $50.1 million for the three months ended March 31, 2017 to $64.3 million for the three months ended March 31, 2018 . Revenue in the U.S. region increased from $223.1 million for the three months ended March 31, 2017 to $225.7 million for the three months ended March 31, 2018 .

Direct costs for the period increased by $21.3 million, or 8.5% , from $250.5 million for the three months ended March 31, 2017 to $271.8 million for the three months ended March 31, 2018 . Direct costs consist primarily of compensation, associated fringe benefits and share based compensation expense for project-related employees and other direct project driven costs. The increase in direct costs during the period arose from an increase in headcount and a corresponding increase in personnel related expenditure of $24.2 million. This increases was offset by a decrease in other direct project related costs of $2.9 million. As a percentage of revenue, direct costs have increased from 43.3% for the three months ended March 31, 2017 to 43.8% for the three months ended March 31, 2018 .

Reimbursable expenses for the period increased by $12.7 million, or 8.7% , from $146.1 million for the three months ended March 31, 2017 to $158.8 million for the three months ended March 31, 2018 . As a percentage of revenue, reimbursable expenses have increased from 25.3% for the three months ended March 31, 2017 to 25.6% for the three months ended March 31, 2018 . The increase in reimbursable expenses is directly related to the increased activity.

Selling, general and administrative expenses for the period decreased by $0.5 million, or 0.6% , from $81.4 million for the three months ended March 31, 2017 to $80.9 million for the three months ended March 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. The net decrease in selling, general and administration expenses for the period of $0.5 million reflects a continued focus on personnel related expenditure and facilities and related costs. As a percentage of revenue, selling, general and administrative expenses, decreased from 14.1% for the three months ended March 31, 2017 to 13.1% for the three months ended March 31, 2018 .

Depreciation expense for the period increased by $1.9 million, or 18.3% , from $10.0 million for three months ended March 31, 2017 to $11.9 million for three months ended March 31, 2018 . Depreciation expense arises principally from continued investment in facilities, information systems and equipment to support the Company’s growth. As a percentage of revenue the depreciation expense for the three months ended March 31, 2018 ( 1.9% ) increased marginally on the percentage of revenue charge for the three months ended March 31, 2017 ( 1.7% ). Amortization expense for the period increased by $0.6 million, or 14.0% , from $4.4 million for the three months ended March 31, 2017 to $5.0 million for the three months ended March 31, 2018 . Amortization expense represents the amortization of intangible assets acquired on business combinations. The main reason for the increase in the amortization expense for the period relates to the additional amortization for the period related to the acquisition of Mapi in July 2017. As a percentage of revenue, amortization expense for the three months ended March 31, 2018 was 0.8% , which is in line with the three months ended March 31, 2017 .

As a result of the above, income from operations for the three months increased by $6.1 million, or 7.1% , from $85.6 million for the three months ended March 31, 2017 to $91.7 million for the three months ended March 31, 2018 . As a percentage of revenue, income from operations for the three months ended March 31, 2018 was 14.8% , which is in line with the three months ended March 31, 2017 .

Income from operations in Ireland increased from a profit of $64.0 million for the three months ended March 31, 2017 to a profit of $69.8 million for the three months ended March 31, 2018 . Income from operations in Ireland is impacted by the Group’s global transfer pricing model (see note 12 Business Segmental Information for further details). Income from operations in our Rest of Europe region increased from $3.7 million for the three months ended March 31, 2017 to $5.2 million for the three months ended March 31, 2018 , while income from operations in our Rest of World region decreased from $7.5 million for the three months ended March 31, 2017 to $4.9 million for the three months ended March 31, 2018 . Income from operations in the U.S. region increased from $10.5 million for the three months ended March 31, 2017 to $11.8 million for the three months ended March 31, 2018 . This reflects the income contribution since acquisition of Mapi, and the impact of refinements to the consideration earned by US subsidiaries under the Group’s global transfer pricing model, offset in part by increased amortization charges.

Interest expense for the period increase by $0.6 million, or 19.4%, from $3.2 million for the three months ended March 31, 2017 to $3.8 million for the three months ended March 31, 2018 . Interest income increased by $0.2 million or 48.3%, from $0.6 million for the three months ended March 31, 2017 to $0.8 million for the three months ended March 31, 2018 .

Provision for income taxes decreased from $11.6 million for the three months ended March 31, 2017 to $10.7 million for the three months ended March 31, 2018 . The Company’s effective tax rate for the three months ended March 31, 2018 was 12.0% compared with 14.0% for the three months ended March 31, 2017 . The Company’s effective tax rate remains principally a function of the distribution of pre-tax profits amongst the territories in which it operates.

Liquidity and Capital Resources

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

Our clinical research and development contracts are generally fixed price with some variable components and range in duration from a few weeks to several years. Revenue from contracts is generally recognized as income on the basis of the relationship between time incurred and the total estimated contract duration or on a fee-for-service basis. 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's duration, in some cases on the achievement of certain milestones. Accordingly, cash receipts do not correspond to costs incurred or revenue recognized on contracts.

	(66,029	)	—	(11,727	)	(92	)	869	(76,979	)

The Company’s cash and short term investment balances at March 31, 2018 amounted to $353.5 million compared with cash and short term investment balances of $360.5 million at December 31, 2017. The Company’s cash and short term investment balances at March 31, 2018 comprised of cash and cash equivalents of $272.0 million and short-term investments of $81.5 million. The Company’s cash and short term investment balances at December 31, 2017 comprised of cash and cash equivalents of $282.9 million and short-term investments of $77.6 million.

On December 15, 2015, ICON Investments Five Unlimited Company issued Senior Notes for aggregate gross proceeds of $350.0 million in a private placement. The Senior Notes will mature on December 15, 2020. Interest payable is fixed at 3.64%, and is payable semi-annually on the Senior Notes on each June 15 and December 15, commencing June 15, 2016. The Senior Notes are guaranteed by ICON plc.

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

The Group also has an uncommitted short-term revolving credit facility of $30 million. No amounts were drawn under this facility at December 31, 2017 or at March 31, 2018 .

Net cash provided by operating activities was $40.5 million for the three months ended March 31, 2018 compared with cash provided by operating activities of $159.3 million for the three months ended March 31, 2017 . This reflects the impact of the increase in revenues and underlying profitability of the Company offset by movements in working capital balances in the period. 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 instalments based on the delivery of certain performance targets or “milestones” (e.g. target patient enrolment 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 are performed. Days revenue outstanding can vary therefore due to, amongst others, the scheduling of contractual milestones over a study or trial duration, the delivery of a particular milestone during the period or the timing of cash receipts from customers. A decrease in the number of days revenue outstanding during a period will result in cash inflows to the Company while an increase in days revenue outstanding will lead to cash outflows. The number of days revenue outstanding at March 31, 2018 was 51 days (under ASC 606) compared to 49 days at December 31, 2017 (under ASC 605). The number of days revenue outstanding at March 31, 2017 was 47 days compared to 50 days at December 31, 2016 .

Net cash used in investing activities was $13.9 million for the three months ended March 31, 2018 compared to net cash used in investing activities of $21.6 million for the three months ended March 31, 2017 . Net cash used in the three months ended March 31, 2018 relates to capital expenditure of $8.3 million, which was mainly comprised of investment in facilities and IT infrastructure. During the three months ended March 31, 2018 $10.2 million was used for the purchase of short term investments, a final consideration payment of $1.6 million was made in respect of the purchase of Mapi and $6.3 million was generated by the sale of short term investments. Net cash used in investing activities during the three months ended March 31, 2017 relates to capital expenditure of $8.3 million, which was mainly comprised of investment in facilities and IT infrastructure. During the three months ended March 31, 2017 $18.0 million was used for the purchase of short term investments and $4.7 million was generated by the sale of short term investments.

Net cash used in financing activities during the three months ended March 31, 2018 amounted to $38.3 million compared to net cash provided by financing activities of $93.7 million for the three months ended March 31, 2017 . Cash outflows in respect of financing includes cash payments in respect of the Company’s share repurchase program totaling $38.2 million during the three months ended March 31, 2018 and financing costs of $0.8 million. In addition, $0.7 million was received by the Company from the exercise of share options. During the three months ended March 31, 2017 , $96.4 million was recognized in relation to the Company's share repurchase program. In addition, $2.8 million was received by the Company from the exercise of share options.

As a result of these cash flows, cash and cash equivalents decreased by $10.9 million for the three months ended March 31, 2018 compared to an increase of $44.8 million for the three months ended March 31, 2017 .
