4. Income Taxes

Income taxes recognized during the three and six months ended June 30, 2015 comprise:

	Three Months Ended				Six Months Ended
	June 30,		June 30,		June 30,		June 30,
	2015		2014		2015		2014
	(In thousands)				(In thousands)
Provision for income taxes	$	9,537	$	7,467	$	20,338	$	14,361

As at June 30, 2015 the Company maintains a $28.2 million liability (December 31, 2014: $25.6 million) for unrecognized tax benefit, which is comprised of $25.4 million (December 31, 2014: $23.2 million) related to items generating unrecognized tax benefits and $2.8 million (December 31, 2014: $2.4 million) for interest and related penalties to such items. The Company recognizes interest accrued on unrecognized tax benefits as an additional income tax expense.

The Company has analyzed 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 2009 through 2014 tax years. The Company does not believe that the outcome of any examination will have a material impact on its financial statements.

5. 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				Six Months Ended
	June 30,		June 30,		June 30,		June 30,
	2015		2014		2015		2014
Weighted average number of ordinary shares outstanding for basic net income per ordinary share		60,244,982		61,934,923		60,263,021		61,855,783
Effect of dilutive share options outstanding		1,556,705		1,408,346		1,586,305		1,434,509
Weighted average number of ordinary shares for diluted net income per ordinary share		61,801,687		63,343,269		61,849,326		63,290,292

6. 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.

Each option granted under the 2008 Employee Plan or the 2008 Consultants Plan (together 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.

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 400,000 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 July 21, 2018.

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, 2015 is eight years.

The following table summarizes option activity for the six months ended June 30, 2015:

	Options Outstanding Number of Shares			Weighted Average Exercise Price		Weighted Average Fair Value		Weighted Average Remaining Contractual Life
Outstanding at December 31, 2014		2,227,700		$	28.00	$	10.40

The following table summarizes the movement in non-vested share options for the six months ended June 30, 2015:

	Options Outstanding Number of Shares			Weighted Average Exercise Price		Weighted Average Fair Value
Non vested outstanding at December 31, 2014		1,203,150		$	30.54	$	10.98
Granted		259,059		$	68.25	$	19.75

Fair value of Stock Options Assumptions

The weighted average fair value of options granted during the six months ended June 30, 2015 and June 30, 2014 was calculated using the Black-Scholes option pricing model.  The weighted average fair values and assumptions used were as follows:

	Six Months Ended
	June 30,			June 30,
	2015			2014
Weighted average fair value	$	19.75		$	12.24
Assumptions:
Expected volatility		30	%		32	%
Dividend yield		0	%		0	%
Risk-free interest rate		1.58	%		1.54	%
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.

12

On April 23, 2013 the Company adopted the 2013 Employees Restricted 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 Restricted Share Units (“RSUs”) and/or Performance Share Units (“PSUs”) 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 six months ended June 30, 2015:

	PSU Outstanding Number of Shares			PSU Weighted Average Fair Value		PSU Weighted Average Remaining Contractual Life		RSU Outstanding Number of Shares			RSU Weighted Average Fair Value		RSU Weighted Average Remaining Contractual Life
Outstanding at December 31, 2014		669,171		$	39.78		1.77		1,038,996		$	35.19		1.67
Granted		269,875		$	68.07				378,804		$	66.85

Outstanding at June 30, 2015		935,065		$	47.24		1.72		1,155,318		$	47.32		1.92

PSUs were awarded to certain key executives of the Company during the six months ended 30 June, 2015. PSUs vest based upon both a service basis and performance basis. The performance element is contingent upon cumulative EPS performance of the Company over a three year period (i.e. for the three year financial period ending December 31, 2018). PSUs with similar EPS performance targets were awarded during the years ended December 31, 2013 and December 31, 2014. 460,553 of the 935,065 PSUs outstanding at June 30, 2015 vest upon the achievement of EPS performance targets.

8. Business Segment Information

The Company determines and presents operating segments based on the information that is internally provided to the Chief Executive Officer, Chief Operating Officer and Chief Financial Officer, who together are considered the Company’s chief operating decision makers, in accordance with FASB ASC 280-10 Disclosures about Segments of an Enterprise and Related Information.

The Company is a contract 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 customer 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.  As such it 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 net 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, 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.

Segment information as at June 30, 2015 and December 31, 2014 and for the three and six months ended June 30, 2015 and June 30, 2014 is as follows:

ICON plc

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, 2014. The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States.

Overview

We are a contract 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 CRO’s 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 June 30, 2015, we employed approximately 11,343 employees, in 81 locations in 37 countries. During the six months ended June 30, 2015 we derived approximately 40.5%, 49.2% and 10.3% of our net revenue in the United States, Europe and Rest of World, respectively.

Revenue consists primarily 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 achievement of certain performance targets or "milestones". Revenue from contracts is recognized on a proportional performance method based on the relationship between time incurred and the total estimated duration of the trial or on a fee-for-service basis according to the particular circumstances of the contract. As is customary in the CRO industry, we contract with third party investigators in connection with clinical trials. All investigator fees and certain other costs, where reimbursed by clients, are, in accordance with industry practice, deducted from gross revenue to arrive at net revenue. As these costs vary from contract to contract, we view net revenue as our primary measure of revenue growth.

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

Termination or delay in the performance of an individual contract may occur for various reasons, including, but not limited to, unexpected or undesired results, production problems resulting in shortages of the drug, adverse patient reactions to the drug, the client’s decision to de-emphasize a particular trial or inadequate patient 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 net revenue yet to be earned from projects awarded by clients. At June 30, 2015 we had a backlog of approximately $3.7 billion, compared with approximately $3.6 billion at December 31, 2014. 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 underlying the backlog, and no assurances can be given on the extent to which we will be able to realize this backlog as net 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.

18

In addition to translationn 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 and usually negotiate currency fluctuation clauses in our contracts which allow for price negotiation if changes in the relative value of those currencies exceed predetermined tolerances.

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.

Results of Operations

Three Months Ended June 30, 2015 compared with Three Months Ended June 30, 2014

The following table sets forth for the periods indicated certain financial data as a percentage of net 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
	June 30, 2015			June 30,  2014			2015 to 2014
							Percentage
	Percentage of Net Revenue						Increase/ (Decrease)
Net revenue		100.0	%		100.0	%		3.4	%
Costs and expenses:
Direct costs		57.9	%		60.4	%		(1.0	)%
Selling, general and administrative		20.9	%		23.3	%		(7.2	)%
Depreciation		2.5	%		2.8	%		(5.7	)%
Amortization		1.2	%		0.7	%		74.3	%
Income from operations		17.5	%		12.8	%		41.1	%

19

Net revenue for the period increased by $12.7 million, or 3.4%, from $376.0 million for the three months ended June 30, 2014 to $388.7 million for the three months ended June 30, 2015. A primary driver of the increase in net revenues during the three months ended June 30, 2015 was net revenues from the acquisition of MediMedia Pharma solutions which was acquired on February 27, 2015 and a full quarter’s revenue during 2015 from the acquisition of Aptiv Solutions which was acquired on May 7, 2014.  In addition, during the three months ended June 30, 2015 $197.8 million or 50.9% of our net revenues were derived from our top 5 customers compared to $184.3 million or 52.7% of net revenues derived from our top 5 customers during the three months ended June 30, 2014. The increased use of strategic partnerships arrangements in recent years has resulted in a greater value of our net revenues being derived from our top five customers, although the addition of new customer accounts over recent quarters has resulted in a reduction in this concentration. For the three months ended June 30, 2015 we derived approximately 42.3%, 47.3% and 10.4% of our net revenue in the United States, Europe and Rest of World, respectively. 

Net revenue in Ireland increased from $88.7 million for the three months ended June 20, 2014to $105.4 million for the three months ended June 30, 2015. Net revenue in Ireland is principally a function of the Company’s global transfer pricing model (see note 8 Business Segmental Information for further details).  Net revenue in our Rest of Europe region decreased from $98.1 million for the three months ended June 30, 2014 to $78.5 million for the three months ended June 30, 2015, while net revenue in our Other region decreased marginally from $41.8 million for the three months ended June 30, 2014 to $40.4 million for the three months ended June 30, 2015.  Net revenues in both of these regions were impacted by the continued strengthening of the U.S. dollar during the period which saw a decrease in their reported value when translated to U.S. dollars. This reduction was offset by a full three months revenue contribution from Aptiv Solutions which was acquired on May 7, 2014.  Net revenue in the U.S. region increased from $147.4 million for the three months ended June 30, 2014 to $164.3 million for the three months ended June 30, 2015.  The increase in net revenue in this region arose primarily from a full three months contribution from the acquisition of Aptiv Solutions and net revenue from MediMedia Pharma Solutions which was acquired on February 27, 2015.

Direct costs for the period decreased by $2.3 million, or 1.0%, from $227.2 million for the three months ended June 30, 2014 to $225.0 million for the three months ended June 30, 2015. 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 decrease in direct costs during the period was driven primarily from the continued strengthening of the U.S. dollar versus exchange rates such as the Euro, amongst others, which has seen a decrease in the reported value of direct costs for operations outside of the United States when translated to U.S. dollars. This decrease was offset by an increase in direct headcount of approximately 600, additional costs from the acquisition of MediMedia Pharma Services and a full quarter’s costs for Aptiv Solutions.  As a percentage of net revenue, direct costs have decreased from 60.4% for the three months ended June 30, 2014 to 57.9% for the three months ended June 30, 2015.

Selling, general and administrative expenses for the period decreased by $6.3 million, or 7.2%, from $87.6 million for the three months ended June 30, 2014 to $81.3 million for the three months ended June 30, 2015. 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. A primary driver of the decrease in selling, general and administrative expenses during the period has been the continued strengthening of the U.S. dollar versus exchange rates such as the Euro, amongst others.  This strengthening has seen a reduction in the reported value of selling, general and administrative expenses during the period for regions outside of the United States. This reduction was offset by increased costs from the acquisition of MediMedia Pharma Solutions and the inclusion of a full three months costs for Aptiv Solutions in the current period.  As a percentage of net revenue, selling, general and administrative expenses, decreased from 23.3% for the three months ended June 30, 2014 to 20.9% for the three months ended June 30, 2015.

Depreciation expense for the period decreased by $0.6 million, or 5.7%, from $10.4 million for the three months ended June 30, 2014 to $9.8 million for three months ended June 30, 2015. Depreciation expense arises principally arises from an investment in facilities, information systems and equipment to support the Company’s growth. As a percentage of net revenue, depreciation expense decreased from 2.8% of net revenues for the three months ended June 30, 2014to 2.5% of net revenues for the three months ended June 30, 2015.  Amortization expense for the period increased by $1.9 million, or 74.3%, from $2.6 million for the three months ended June 30, 2014to $4.5 million for the three months ended June 30, 2015. Amortization expense represents the amortization of intangible assets acquired on business combinations. The increase in amortization expense during the period arises predominately from amortization expense associated with the Company’s estimate of intangible assets arising on the acquisition of MediMedia Pharma Solutions.  As a percentage of net revenue, amortization expense increased from 0.7% of net revenues for the three months ended June 30, 2014to 1.2% for the three months ended June 30, 2015.

20

As a result of the above, income from operations for the three months increased by $19.8 million, or 41.1%, from $48.3 million for the three months ended June 30, 2014to $68.1 million for the three months ended June 30, 2015. As a percentage of net revenue, income from operations increased from 12.8% of net revenues for the three months ended June 30, 2014to 17.5% of net revenues for the three months ended June 30, 2015.

Income from operations in Ireland increased from $26.7 million for the three months ended June 30, 2014to $49.4 million for the three months ended June 30, 2015. Income from operations in Ireland is impacted by the Group’s global transfer pricing model (see note 8 Business Segmental Information for further details).   Income from operations in our Rest of Europe region decreased from $8.0 million for the three months ended June 30, 2014 to $3.5 million for the three months ended June 30, 2015, while income from operations in our Other region decreased marginally from $3.9 million for three months ended June 30, 2014 to $2.6 million for the three months ended June 30, 2015. Income from operations in both of these regions was impacted by the continued strengthening of the U.S. dollar during the period which saw a decrease in the reported value of both revenues and costs when translated to U.S. dollars.  This reduction was offset by a full three months contribution from Aptiv Solutions in the current period. Income from operations in the U.S. region increased from $9.6 million for the three months ended June 30, 2014 to $12.6 million for the three months ended June 30, 2015.  Income from operations in this region was positively impacted by the acquisition of MediMedia Pharma Solutions and a full three months contribution from Aptiv Solutions.

Interest expense for the period decreased by $0.07 million or 23%, from $0.3 million for the three months ended June 30, 2014 to $0.23 million for the three months ended June 30, 2015. Interest income decreased by $0.04 million or 15%, from $0.26 million for the three months ended June 30, 2014to $0.22 million for the three months ended June 30, 2015.

Provision for income taxes for the period increased from $7.5 million for the three months ended June 30, 2014to $9.5 million for the three months ended June 30, 2015.  The Company’s effective tax rate for the three months ended June 30, 2015 was 14.0% compared with 15.5% for the three months ended June 30, 2014. The Company’s effective tax rate is principally a function of the distribution of pre-tax profits amongst the territories in which it operates.

Net revenue for the period increased by $51.2 million, or 7.1%, from $725.7 million for the six months ended June 30, 2014 to $776.9 million for the six months ended June 30, 2015. The primary driver of the increase in net revenues during the six months ended June 30, 2015 was the inclusion of net revenues from the acquisition of Aptiv Solutions, which was acquired on May 7, 2014, together with net revenues from MediMedia Pharma Solutions which was acquired on February 27, 2015. During the six months ended June 30, 2015 $406.8 million or 52.4% of our net revenues were derived from our top 5 customers compared to $376.8 million or 51.9% of net revenues derived from our top 5 customers during the six months ended June 30, 2014. The increased use of strategic partnerships arrangements in recent years has resulted in a greater portion of our net revenues being derived from our top five customers.  While there has been a marginal increase in the percentage concentration for the six months ended June 30, 2015 compared to the six months ended June 30, 2014, the addition of new accounts in recent quarters has led a decrease in this overall percentage in the three month ended June 30, 2015.  For the six months ended June 30, 2015 we derived approximately 40.5%, 49.2% and 10.3% of our net revenue in the United States, Europe and Rest of World, respectively. 

Net revenue in Ireland increased from $174.1 million for the six months ended June 20, 2014to $219.5 million for the six months ended June 30, 2015. Net revenue in Ireland is principally a function of the Company’s global transfer pricing model (see note 8 Business Segmental Information for further details).  Net revenue in our Rest of Europe region decreased from $184.5 million for the six months ended June 30, 2014 to $162.6 million for the six months ended June 30, 2015, while net revenue in our Other region decreased marginally from $72.3 million for the six months ended June 30, 2014 to $75.3 million for the six months ended June 30, 2015.  Net revenues in both of these regions were impacted by the continued strengthening of the U.S. dollar during the period which saw a decrease in their reported value when translated to U.S. dollars. This reduction was offset by a full six months revenue contribution from Aptiv Solutions which was acquired on May 7, 2014.  Net revenue in the U.S. region increased from $272.7 million for the six months ended June 30, 2014 to $291.9 million for the six months ended June 30, 2015.  The increase in net revenue in this region arose primarily from a full six months contribution from the acquisition of Aptiv Solutions and net revenue from MediMedia Pharma Solutions which was acquired on February 27, 2015.

Direct costs for the period increased by $9.7 million, or 2.2%, from $443.3 million for the six months ended June 30, 2014 to $453.0 million for the six months ended June 30, 2015. 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 primarily from an increase in direct headcount of approximately 300 heads, additional costs from the acquisition of MediMedia Pharma Services and full quarter’s costs for Aptiv Solutions.  In addition, the continued strengthening of the U.S. dollar versus exchange rates such as the Euro, amongst others, has seen a decrease in the reported value of direct costs for operations outside of the United States when translated to U.S. dollars.  As a percentage of net revenue, direct costs have decreased from 61.1% for the six months ended June 30, 2014 to 58.3% for the six months ended June 30, 2015.

Selling, general and administrative expenses for the period decreased by $5.7 million, or 3.4%, from $166.6 million for the six months ended June 30, 2014 to $160.9 million for the six months ended June 30, 2015. 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. A primary driver of the decrease in selling, general and administrative expenses during the period has been the continued strengthening of the U.S. dollar versus exchange rates such as the Euro, amongst others.  This strengthening has seen a reduction in the reported value of selling, general and administrative expenses during the period for regions outside of the United States. This reduction was offset by increased costs from the acquisition of MediMedia Pharma Solutions and the inclusion of a full six months costs for Aptiv Solutions in the current period.  As a percentage of net revenue, selling, general and administrative expenses, decreased from 23.0% for the six months ended June 30, 2014 to 20.7% for the six months ended June 30, 2015.

Depreciation expense for the period decreased by $0.3 million, or 1.8%, from $20.0 million for the six months ended June 30, 2014 to $19.7 million for the six months ended June 30, 2015. Depreciation expense arises principally arises from an investment in facilities, information systems and equipment to support the Company’s growth. As a percentage of net revenue, depreciation expense decreased from 2.9% of net revenues for the six months ended June 30, 2014 to 2.5% for the six months ended June 30, 2015.  Amortization expense for the period increased by $4.1million, or 91.6%, from $4.5 million for the six months ended June 30, 2014 to $8.5 million for the six months ended June 30, 2015. Amortization expense represents to the amortization of intangible assets acquired on business combinations. The increase in the amortization expense for the period relates to the acquisition of Aptiv Solution, together with the amortization expense associated with the Company’s estimate of intangible assets arising on the acquisition of MediMEdia Pharma Solutions. As a percentage of net revenue, amortization expense increased from 0.6% of net revenues for the six months ended June 30, 2014 to 1.1% for the six months ended June 30, 2015.

22

As a result of the above, income from operations for the six months ended June 30, 2015 increased by $43.5 million, or 47.6%, from $91.3 million for the six months ended June 30, 2014 to $134.8 million for the six months ended June 30, 2015. As a percentage of net revenue, income from operations increased from 12.4% of net revenues for the six months ended June 30, 2014 to 17.4% of net revenues for the six months ended June 30, 2015.

Income from operations in Ireland increased from $54.9 million for the six months ended June 30, 2014to $97.0 million for the six months ended June 30, 2015. Income from operations in Ireland is impacted by the Group’s global transfer pricing model (see note 8 Business Segmental Information for further details).   Income from operations in our Rest of Europe region decreased from $14.4 million for the six months ended June 30, 2014 to $10.4 million for the six months ended June 30, 2015, while income from operations in our Other region decreased marginally from $5.7 million for six months ended June 30, 2014 to $5.1 million for the six months ended June 30, 2015. Income from operations in both of these regions was impacted by the continued strengthening of the U.S. dollar during the period which saw a decrease in the reported value of both revenues and costs when translated to U.S. dollars.  This reduction was offset by a full six months contribution from Aptiv Solutions in the current period. Income from operations in the U.S. region increased from $16.3 million for the six months ended June 30, 2014 to $22.4 million for the six months ended June 30, 2015.  Income from operations in this region was positively impacted by the acquisition of MediMedia Pharma Solutions during the period and a full six months contribution from Aptiv Solutions.

Interest expense for the period decreased from $0.56 million for the six months ended June 30, 2014 to $0.51 million for the six months ended June 30, 2015. Interest income increased from $0.6 million for the six months ended June 30, 2014 to $0.5 million for the six months ended June 30, 2015.

Provision for income taxes for the period increased from $14.4 million for the six months ended June 30, 2014 to $20.3 million for the six months ended June 30, 2015.  The Company’s effective tax rate for the six months ended June 30, 2014 was 15.1% compared with 15.7% for the six months ended June 30, 2014. The Company’s effective tax rate is 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 and revenue recognized on contracts.

The Company’s net cash balances amounted to $132.2 million at June 30, 2015 compared to $216.0 million at December 31, 2014.  The Company’s net cash balances comprise cash and cash equivalent and short term investments, offset by amounts drawn under negotiated banking facilities.  At June 30, 2015 cash and cash equivalents amounted to $107.5 million, short term investments $84.7 million while amounts drawn under the Company’s negotiated banking facility amounted to $60.0 million.  At December 31, 2014 cash and cash equivalents amounted to $118.9 million, short term investments $97.1 million while no amounts were drawn under the Company’s negotiated banking facility. In February 2015, the Company completed the acquisition of MediMedia Pharma Solutions resulting in a cash outflow totalling $105.1 million, while the Company also paid $58.2 million to repurchases shares under its share repurchase program during the period.

On June 30, 2014 the Company entered into a five year committed multi-currency revolving credit facility for $100.0 million with Citibank, JP Morgan, Santander and Barclays Bank. Each bank subject to the agreement has committed $25 million to the facility, with equal terms and conditions in place with all institutions. The facility bears interest at LIBOR plus a margin and includes certain composite guarantees, indemnities and pledges in favour of the banks. At June 30, 2015, the company had drawn $60 million of this facility. Amounts available to the Group under the facility amounted to $40.0 million at June 30, 2015.

23

Net cash provided by operating activities was $89.2 million for the six months ended June 30, 2015 compared with cash used in operating activities of $16.3 million for the six months ended June 30, 2014. The increase in cash provided by operating activities during the six months ended June 30, 2015 arose primarily form an increase in both revenues and margins within the business, together with a lower increase in the number of days revenue outstanding over the comparative period.  Revenue outstanding which comprises accounts receivable and unbilled revenue, less payments on account.  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 achievement 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 achievement 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 day’s revenue outstanding at June 30, 2015 was 45 days compared to 40 days at December 31, 2014.  The number of day’s revenue outstanding at June 30, 2014was 40 days compared to 32 days at December 31, 2013.

Net cash used in investing activities was $114.7 million for the six months ended June 30, 2015 compared to net cash used in investing activities of $86.0 million for the six months ended June 30, 2014. Net cash used in the six months ended June 30, 2015 arose principally from cash paid to acquire MediMedia Pharma Solutions. Capital expenditure for the six months ended June 30, 2015 amounted to $24.1 million and comprised mainly of expenditure on global infrastructure and information technology systems to support the Company’s growth.  During the six months ended June 30, 2015 the Company received a net $12.5 million from the sale of short-term investments.

Net cash provided by financing activities during the six months ended June 30, 2015 amounted to $15.3 million compared to $1.5 million for the six months ended June 30, 2014.  During the six months ended June 30, 2015 the Company received $60.0 million from the drawdown of amounts under its negotiated banking facility, together with $13.5 million from the exercise of share options.  This was offset by $58.2 million paid to repurchase ordinary shares under the Company’s share repurchase program (including $0.3 million share repurchase costs).  During the six months ended June 30, 2014 the Company received $12.3 million from the sale of share options.  This was offset by $11.5 million paid by the Company to repurchase ordinary shares.

Inflation

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

Legal Proceedings

We are not party to any litigation or other legal proceedings that we believe could reasonably be expected to have a material adverse effect on our business, results of operations and financial condition.

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.

Each option granted under the 2008 Employee Plan or the 2008 Consultants Plan (together 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.

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 400,000 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 July 21, 2018.

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, 2015 is eight years.

The following table summarizes option activity for the six months ended June 30, 2015:

	Options Outstanding Number of Shares			Weighted Average Exercise Price		Weighted Average Fair Value		Weighted Average Remaining Contractual Life
Outstanding at December 31, 2014		2,227,700		$	28.00	$	10.40

Exercisable at June 30, 2015		962,227		$	25.88	$	9.91		3.51

The Company has outstanding options with fair values ranging from $5.88 to $19.78 per option or a weighted average fair value of $11.70 per option. The Company issues ordinary shares for all options exercised. The total amount of fully vested share options which remained outstanding at June 30, 2015, was 962,227. Fully vested share options at June 30, 2015, have an average remaining contractual term of 3.51 years, an average exercise price of $25.88 and a total intrinsic value of $39.9 million. The total intrinsic value of options exercised during the six months ended June 30, 2015 was $12.6 million (June 30, 2014: $10.9 million).

The following table summarizes the movement in non-vested share options for the six months ended June 30, 2015:

	Options Outstanding Number of Shares			Weighted Average Exercise Price		Weighted Average Fair Value
Non vested outstanding at December 31, 2014		1,203,150		$	30.54	$	10.98
Granted		259,059		$	68.25	$	19.75
Vested		(377,436	)	$	28.22	$	10.48
Forfeited		(29,144	)	$	25.19	$	10.20
Non vested outstanding at  June 30, 2015		1,055,629		$	40.77	$	13.33

Fair value of Stock Options Assumptions

The weighted average fair value of options granted during the six months ended June 30, 2015 and June 30, 2014 was calculated using the Black-Scholes option pricing model.  The weighted average fair values and assumptions used were as follows:

	Six Months Ended
	June 30,			June 30,
	2015			2014
Weighted average fair value	$	19.75		$	12.24
Assumptions:
Expected volatility		30	%		32	%
Dividend yield		0	%		0	%
Risk-free interest rate		1.58	%		1.54	%
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 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 Restricted Share Units (“RSUs”) and/or Performance Share Units (“PSUs”) 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 six months ended June 30, 2015:

	PSU Outstanding Number of Shares			PSU Weighted Average Fair Value		PSU Weighted Average Remaining Contractual Life		RSU Outstanding Number of Shares			RSU Weighted Average Fair Value		RSU Weighted Average Remaining Contractual Life
Outstanding at December 31, 2014		669,171		$	39.78		1.77		1,038,996		$	35.19		1.67

Outstanding at June 30, 2015		935,065		$	47.24		1.72		1,155,318		$	47.32		1.92

PSUs were awarded to certain key executives of the Company during the six months ended 30 June, 2015. PSUs vest based upon both a service basis and performance basis. The performance element is contingent upon cumulative EPS performance of the Company over a three year period (i.e. for the three year financial period ending December 31, 2018). PSUs with similar EPS performance targets were awarded during the years ended December 31, 2013 and December 31, 2014. 460,553 of the 935,065 PSUs outstanding at June 30, 2015 vest upon the achievement of EPS performance targets.

Non-cash stock compensation expense

Non-cash stock compensation expense for the three and six months ended June 30, 2015 has been allocated as follows:

	Three Months Ended				Six Months Ended
	June 30,		June 30,		June 30,		June  30,
	2015		2014		2015		2014

	$	8,969	$	5,706	$	15,012	$	9,751

Total non-cash stock compensation expense not yet recognized at June 30, 2015 amounted to $83.4 million.  The weighted average period over which this is expected to be recognized is 2.4 years.  Total tax benefit recognized in additional paid in capital related to the non-cash compensation expense amounted to $2.5 million for the six months ended June 30, 2015 (June 30, 2014: $0.8 million).

Net income per ordinary share

Net income per ordinary share

5. 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				Six Months Ended
	June 30,		June 30,		June 30,		June 30,
	2015		2014		2015		2014

Effect of dilutive share options outstanding		1,556,705		1,408,346		1,586,305		1,434,509
Weighted average number of ordinary shares for diluted net income per ordinary share		61,801,687		63,343,269		61,849,326		63,290,292

Business Segment Information

8. Business Segment Information

The Company determines and presents operating segments based on the information that is internally provided to the Chief Executive Officer, Chief Operating Officer and Chief Financial Officer, who together are considered the Company’s chief operating decision makers, in accordance with FASB ASC 280-10 Disclosures about Segments of an Enterprise and Related Information.

The Company is a contract 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 customer 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.  As such it 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 net 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, 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.
