GENERAL

As used herein, “ICON”, the “Company” and “we” refer to ICON plc and its consolidated subsidiaries, unless the context requires otherwise.

Business

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 Clinical Development - from compound selection to Phase I-IV clinical studies.

We believe that we are one of a select group of CROs with the capability and expertise to conduct clinical trials in most major therapeutic areas on a global basis. At September 30, 2011 we had approximately 8,350 employees, in 79 locations in 39 countries, providing Phase I - IV Clinical Trial Management, Drug Development Support Services, Data Management and Biostatistical, Central Laboratory, Imaging and Contract Staffing services. We have the operational flexibility to provide development services on a stand-alone basis or as part of an integrated “full service” solution.

Headquartered in Dublin, Ireland, we began operations in 1990 and have expanded our business through internal growth and strategic acquisitions. ICON plc’s principal executive office is located at: South County Business Park, Leopardstown, Dublin 18, Republic of Ireland. The contact telephone number of this office is 353 (1) 291 2000. For the three months ended September 30, 2011 we derived approximately 43.2%, 43.8% and 13.0% of our net revenue in the United States, Europe and Rest of World, respectively.

During the three months ended March 31, 2011 the Company commenced a review of its operations to improve resource utilization within the business and better align resources to current and future growth opportunities of the business.  This review resulted in the adoption of an initial restructuring plan (the “Q1 Restructuring Plan”), which resulted in the closure of the Company’s facility in Edinburgh, United Kingdom and resource rationalizations in certain of the more mature markets in which it operates.  A restructuring charge of $5.0 million in respect of this plan was recognized during the three months ended March 31, 2011, $1.0 million in respect of lease termination and exit costs associated with the closure of the Edinburgh facility and $4.0 million in respect of workforce reductions. $3.5 million of costs recognised under the Q1 Restructuring Plan related to the clinical research segment, while $1.5 million related to our central laboratory business.  During the three months ended September 30, 2011 the Company implemented a further restructuring plan (the “Q3 Restructuring Plan”) which resulted in the relocation of the Company’s facility in Maryland, USA; and further resource rationalizations.  A restructuring charge of $4.8 million was recognized during the three months ended September 30, 2011 in respect of this plan, $0.9 million in respect of lease termination and exit costs associated with the closure of the existing Maryland facility and $3.9 million in respect of workforce reductions.  All costs recognised under the Q3 Restructuring Plan related to the clinical research segment.

4. Income Taxes

As at September 30, 2011 the Company maintains a $8.3 million liability (December 31, 2010: $9.7 million) for unrecognized tax benefit, which is comprised of $6.7 million (December 31, 2010: $8.1 million) related to items generating unrecognized tax benefits and $1.6 million (December 31, 2010: $1.8 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 2006 through 2010 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				Nine Months Ended
	September 30,		September 30,		September 30,		September 30,
	2011		2010		2011		2010

6. Stock 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 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 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 may grant options to officers and other employees of the Company or its subsidiaries for the purchase of ordinary shares.  Each grant of an option under the 2003 Share Option Plan will be evidenced by a stock option agreement between the employee and the Company. The exercise price will be specified in each Stock Option Agreement.

An aggregate of 6.0 million ordinary shares have been reserved under the 2003 Share Option Plan; and, in no event will the number of ordinary shares that may be issued pursuant to options awarded under the 2003 Share Option 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 determines otherwise. Further, the maximum number of ordinary shares with respect to which options may be granted under the 2003 Share Option Plan during any calendar year to any employee shall be 400,000 ordinary shares.  No options can be granted after January 17, 2013.

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 September 30, 2011 is eight years.

The Company has granted options with fair values ranging from $3.68 to $13.93 per option or a weighted average fair value of $7.15 per option.  The Company issues new ordinary shares for all options exercised. The total amount of fully vested share options which remained outstanding at September 30, 2011 was 2,553,258.  Fully vested share options at September 30, 2011 have an average remaining contractual term of 3.6 years, an average exercise price of $19.64 and a total intrinsic value of $7.7 million. The total intrinsic value of options exercised during the nine months ended September 30, 2011 was $1.5 million (September 30, 2010: $11.4 million).

The following table summarizes the movement in non-vested share options during the nine months ended September 30, 2011:

	Options Outstanding Number of Shares			Weighted Average Exercise Price		Weighted Average Fair Value
Non vested outstanding at December 31, 2010		2,673,674		$	24.76	$	9.48

Stock Option Fair Values and Assumptions

The weighted average fair value of options granted during the period ended September 30, 2011 and September 30, 2010 was calculated using the Black-Scholes option pricing model.  The weighted average fair values and assumptions used were as follows:

	Nine Months Ended
	September 30,		September 30,
	2011		2010
Weighted average fair value	$	8.53	$	9.15
Assumptions:
Expected volatility		45%		45%
Dividend yield		0%		0%
Risk-free interest rate		1.5% - 2.3%		1.7%
Expected life	5 years		4.05 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

The Company has awarded restricted Share Units (“RSU’s”) to certain key executives of the Group.  Details of RSU’s granted during the nine months ended September 30, 2011 were as follows:

RSU’s Awarded	Date of Award	Vesting Date	Market Price on Date of Award
100,000	February 10, 2011	February 10, 2016	$22.11
120,000	March 3, 2011	March 3, 2014	$20.28
10,000	June 7, 2011	June 7, 2014	$24.60

The Company also awarded RSU’s in prior periods.  On August 7, 2008 the Company awarded 6,280 RSU’s to certain key employees of the Group.  These RSU’s vested over periods ranging from February 26, 2009 to February 26, 2011.  The market value of the Company’s ordinary shares on date of award was $41.95.  On August 16, 2010 the Company issued 2,512 ordinary shares relating to certain of these RSU awards.  On May 20, 2011 the Company issued a further 3,768 ordinary shares relating to the remaining RSU awards.

7. Segment Information

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

The Company operates predominantly in the contract clinical research industry providing a broad range of clinical research and integrated product development services on a global basis for the pharmaceutical and biotechnology industries. Historically, the Company organized, operated and assessed its business in two segments, the clinical research segment and the central laboratory segment, which includes the Company’s central laboratories located in Dublin, New York, India, Singapore and China. During the year ended December 31, 2009 management determined that its clinical research and central laboratory businesses operate in the same clinical research market, have a similar customer profile, are subject to the same regulatory environment, support the development of new clinical therapies and are so economically similar, reporting their results on an aggregated basis would be more useful to users of the Company’s financial statements. In addition, the central laboratory division did not reach the thresholds of net revenue, income from operations and total assets as a requirement for being reported as a separate segment.  Accordingly, the Company consolidated and reclassified the results of the former central laboratory segment into the clinical research segment for the three and nine months ended September 30, 2010.

During the year ended December 31, 2010 the Company incurred losses in its central laboratory business, which in accordance with FASB ASC 280-10 Disclosures about Segments of an Enterprises and Related Information requires it to be reported as a separate segment.  Accordingly the Company has disclosed two reportable segments for the three and nine months ended September 30, 2011.  The Company has reclassified the results of the central laboratory segment from the clinical research segment for three and nine months ended September 30, 2011.

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

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, 2010. 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 Clinical Development - from compound selection to Phase I-IV clinical studies. We have the operational flexibility to provide development services on a stand-alone basis or as part of an integrated “full service” solution. Our preferred approach is to use dedicated teams to achieve optimum results, but we can implement a range of resourcing models to suit client requirements, and increasingly our teams are flexibly applied to minimize costs for our clients.

In a highly fragmented industry, we are one of a small number of companies with the capability and expertise to conduct clinical trials in all major therapeutic areas on a global basis. Currently, we have approximately 8,350 employees, in 79 locations in 39 countries, providing Phase I - IV Clinical Trial Management, Drug Development Support Services, Data Management, Biostatistics, Central Laboratory, Imaging and Contract Staffing services.

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 for contracts is recognized using 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.

Our backlog consists of potential net revenue yet to be earned from projects awarded by clients. At September 30, 2011 we had a backlog of approximately $2.2 billion, compared with approximately $1.9 billion at December 31, 2010.  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 that we will be able to realize this backlog as net revenue.

Direct costs consist primarily of compensation, associated fringe benefits and share based compensation expense for project-related employees and other direct project driven costs. Selling, general and administrative expenses comprise compensation, related fringe benefits and share based compensation expense for non project-related employees, recruitment expenditure, professional service costs, advertising costs and all costs related to facilities and information systems.

As the nature of our business involves the management of projects having a typical duration of one to three 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.

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.

21

In addition to translation exposures, we are also subject to transaction exposures because the currency in which contracts are priced can be different from the currencies in which costs relating to those contracts are incurred.  Our operations in the United States are not materially exposed to such currency differences as the majority of our revenues and costs are in U.S. dollars. However, outside the United States the multinational nature of our activities means that contracts are usually priced in a single currency, most often U.S. dollars, Euros or pounds Sterling, 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 of operations 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.

Direct costs in our clinical research segment increased by $20.8 million, or 16.7%, from $124.7 million for the three months ended September 30, 2010 to $145.5 million for the three months ended September 30, 2011.  The Company has entered a number of strategic relationships with sponsors in recent months and further expanded operations in certain territories. This has necessitated significant upfront investment in personnel and related infrastructure in advance of anticipated revenue flows from this business.  In our central laboratory business, direct costs decreased by $2.0 million, or 13.5%, from $14.8 million for the three months ended September 30, 2010 to $12.8 million for the three months ended September 30, 2011. The decrease in direct costs in our central laboratory business during the three months ended September 30, 2011 has resulted principally from a reduction in personnel related costs and laboratory costs during the period, a result of restructuring activities undertaken during the three months ended March 31, 2011 and ongoing cost management. Direct costs as a percentage of net revenue increased to 65.8% for the three months ended September 30, 2011 from 61.9% for the three months ended September 30, 2010.

Selling, general and administrative expense for the period increased by $11.6 million, or 19.3%, from $60.0 million for the three months ended September 30, 2010 to $71.6 million for the three months ended September 30, 2011. The increase in selling, general and administrative expense for the period arose primarily from an increase in personnel related expenditure of $6.5 million, including increases in recruitment expenditure, travel costs for non project-related employees and key employee retention costs, an increase in facility and information systems costs of $4.7 million, an increase in professional service costs of $3.2 million, and an increase in other general overhead costs of $0.6million.  As a percentage of net revenue, selling, general and administrative expenses increased from 26.7% for the three months ended September 30, 2010 to 29.7% for the three months ended September 30, 2011.

Depreciation and amortization expense for the period increased by $1.7 million, or 21.3%, from $8.0 million for the three months ended September 30, 2010 to $9.7 million for the three months ended September 30, 2011. As a percentage of net revenue, depreciation and amortization expense increased from 3.6%  for the three months ended September 30, 2010 to 4.0% for the three months ended September 30, 2011.

During the three months ended March 31, 2011 the Company commenced a review of its operations to improve resource utilization within the business and better align resources to current and future growth opportunities of the business.  This review resulted in the adoption of an initial restructuring plan (the “Q1 Restructuring Plan”), the closure of the Company’s facility in Edinburgh, United Kingdom and resource rationalizations in certain of the more mature markets in which it operates.  A restructuring charge of $5.0 million in respect of this plan was recognized during the three months ended March 31, 2011, $1.0 million in respect of lease termination and exit costs associated with the closure of the Edinburgh facility and $4.0 million in respect of workforce reductions.  $3.5 million of costs recognised under the Q1 Restructuring Plan related to the clinical research segment, while $1.5 million related to our central laboratory business.  During the three months ended September 30, 2011 the Company implemented a further restructuring plan (the “Q3 Restructuring Plan”) which resulted in the relocation of the Company’s facility in Maryland, USA; and further resource rationalizations.  A restructuring charge of $4.8 million was recognized during the three months ended September 30, 2011 in respect of this plan, $0.9 million in respect of lease termination and exit costs associated with the closure of the existing Maryland facility and $3.9 million in respect of workforce reductions. All costs recognised under the Q3 Restructuring Plan related to the clinical research segment.

As a result of the above, income from operations for the period decreased by $21.3 million, from $17.6 million for the three months ended September 30, 2010 to ($3.7) million for the three months ended September 30, 2011. As a percentage of net revenue, income from operations decreased from 7.8% for the three months ended September 30, 2010 to (1.5)% for the three months ended September 30, 2011. In our clinical research segment, income from operations decreased from 12.0% of net revenue for the three months ended September 30, 2010 to (1.7)% of net revenue for the three months ended September 30, 2011, a result of our significant upfront investment in personnel in this business. In our central laboratory business, income/(loss) from operations was (50.9)% for the three months ended September 30, 2010 compared to a 0.6% for the three months ended September 30, 2011.  The improvement in performance in our central laboratory business during the three months ended September 30, 2011 has resulted from a combination of revenue flows from increased business wins in recent quarters, restructuring activities undertaken during the three months ended March 31, 2011 and ongoing cost management.

Excluding the impact of restructuring charges recognized during the three months ended September 30, 2011, income from operations decreased by $16.5 million, from $17.6 million for the three months ended September 30, 2010 to $1.1 million for the three months ended September 30, 2011.  As a percentage of net revenue, income from operations excluding restructuring costs decreased from 7.8% for the three months ended September 30, 2010 to 0.5% for the three months ended September 30, 2011.  In our clinical research segment, income from operations excluding restructuring costs decreased from 12.0% of net revenue for the three months ended September 30, 2010 to 0.5% of net revenue for the three months ended September 30, 2011.

Interest expense for the period decreased from $0.3 million for the three months ended September 30, 2010 to $0.2 million for the three months ended September 30, 2011.  This decrease arose from reduced commitment fees payable on negotiated facilities, arising from the reduction in amounts available to draw under such facilities over the period since September 30, 2010. Interest income for the three months ended September 30, 2011 decreased from $0.5 million for the three months ended September 30, 2010 to $0.4 million for the three months ended September 30, 2011.

Provision for income taxes for the period decreased from a net tax credit of $2.0 million for the three months ended September 30, 2010 to a net tax credit of $0.9 million for the three months ended September 30, 2011.  During the three months ended September 30, 2011 the Company released $2.0 million in provisions for unrecognized tax benefits, arising from both the settlement of positions with the relevant tax authorities and the expiration of the relevant statute of limitations in certain jurisdictions, allowing for the recognition of these benefits during the three months ended September 30, 2011.  During the three months ended September 30, 2010, the Company released $6.0 million in provisions for unrecognized tax benefits, arising from both the settlement of positions with the relevant tax authorities and the expiration of the relevant statute of limitations in certain jurisdictions, allowing for the recognition of these benefits during the three months ended September 30, 2010.

The Company has entered a number of strategic relationships with sponsors in recent months and further expanded operations in certain territories. This has necessitated significant upfront investment in personnel and related infrastructure in advance of anticipated revenue flows from this business.  In our central laboratory business, direct costs increased by $3.2 million, or 9.4%, from $33.9 million for the nine months ended September 30, 2010 to $37.1 million for the nine months ended September 30, 2011.

The increase in selling, general and administrative expense for the period arose primarily from an increase in facilities and information costs of $10.5 million, an increase in personnel related expenditure of $6.4 million, including increases in recruitment expenditure, travel costs associated with non project-related employees and key employee retention costs, an increase in professional service costs of $8.7 million and an increase in other general overhead costs of $0.5 million. These increases were offset by the release of certain non-recurring tax related provisions of approximately $6.0 million in both our clinical research and central laboratory businesses, arising from the receipt of additional information in relation to these items    As a percentage of net revenue, selling, general and administrative expense, increased from 25.6% for the nine months ended September 30, 2010 to 26.9% for the nine months ended September 30, 2011.

Depreciation and amortization expense for the period increased by $3.0 million, or 12.0%, from $25.0 million for the nine months ended September 30, 2010 to $28.0 million for the nine months ended September 30, 2011. As a percentage of net revenue, depreciation and amortization expense increased from 3.7% for the nine months ended September 30, 2010 to 4.0% for the nine months ended September 30, 2011.

During the three months ended March 31, 2011 the Company commenced a review of its operations to improve resource utilization within the business and better align resources to current and future growth opportunities of the business.  This review resulted in the adoption of an initial restructuring plan (the “Q1 Restructuring Plan”), the closure of the Company’s facility in Edinburgh, United Kingdom and resource rationalizations in certain of the more mature markets in which it operates.  A restructuring charge of $5.0 million in respect of this plan was recognized during the three months ended March 31, 2011, $1.0 million in respect of lease termination and exit costs associated with the closure of the Edinburgh facility and $4.0 million in respect of workforce reductions. $3.5 million of costs recognised under the Q1 Restructuring Plan related to the clinical research segment, while $1.5 million related to our central laboratory business.  During the three months ended September 30, 2011 the Company implemented a further restructuring plan (the “Q3 Restructuring Plan”) which resulted in the relocation of the Company’s facility in Maryland, USA; and further resource rationalizations.  A restructuring charge of $4.8 million was recognized during the three months ended September 30, 2011 in respect of this plan, $0.9 million in respect of lease termination and exit costs associated with the closure of the existing Maryland facility and $3.9 million in respect of workforce reductions.  All costs recognised under the Q3 Restructuring Plan related to the clinical research segment.

As a result of the above, income from operations for the period decreased by $47.3 million, from $70.1 million for the nine months ended September 30, 2010 to $22.8 million for the nine months ended September 30, 2011.  As a percentage of net revenue, income from operations decreased from 10.5% for the nine months ended September 30, 2010 to 3.2% for the nine months ended September 31, 2011. In our clinical research segment, income from operations as a percentage of net revenue decreased from 12.7% for the nine months ended September 30, 2010 to 4.1% for the nine months ended September 30, 2011.  In our central laboratory business, income/(loss) from operations was (18.5)% for the nine months ended September 30, 2010 compared to (6.7)% for the nine months ended September 30, 2011.

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, 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 cash and short-term investment balances at September 30, 2011 amounted to $166.1 million compared with cash and short-term investment balances of $255.7 million at December 31, 2010.  The Company’s cash and short-term investment balances at September 30, 2011 comprised cash and cash equivalents $126.8 million and short-term investments $39.3 million.  The Company’s cash and short-term investment balances at December 31, 2010 comprised cash and cash equivalents $255.7 million.  Additional amounts available to the Group under negotiated facilities amounted to $150.0 million at September 30, 2011 compared to $55.9 million at December 31, 2010.

Net cash used in operating activities was $17.6 million for the nine months ended September 30, 2011 compared with net cash provided by operating activities of $55.5 million for the nine months ended September 30, 2010.  The most significant influence on our operating cash flow is revenue outstanding, which comprises accounts receivable and unbilled revenue, less payments on account. The dollar values of these amounts and the related days revenue outstanding can vary due to the achievement of contractual milestones, including contract signing, and the timing of cash receipts.  The decrease in cash flow from operating activities during the nine months ended September 30, 2011 arose primarily from a decrease in net income together with an increase in the number of days revenue outstanding during the period.  The number of days revenue outstanding at September 30, 2011 was 52 days compared to 37 days at December 31, 2010.

Net cash used in investing activities was $118.7 million for the nine months ended September 30, 2011 compared to net cash provided by investing activities of $21.9 million for the nine months ended September 30, 2010. Net cash used in/provided by investing activities comprises primarily of capital expenditure, the purchase and sale of short-term investments and cash paid for acquisitions.  Capital expenditure for the nine months ended September 30, 2011 amounted to $24.6 million, compared to $23.9 million for the nine months ended September 30, 2010 and comprised primarily of expenditure on global infrastructure and information technology systems to support the Company’s growth. During the nine months ended September 30, 2010 the Company realized a net $49.2 million from the sale of its short-term investments. Amounts realized from the sale of short-term investments during the nine months ended September 30, 2010 were reinvested in cash equivalents.  During the nine months ended September 30, 2011 the Company invested a net $39.6 million in short-term investments.

Cash paid for acquisitions during the nine months ended September 30, 2011 amounted to $62.8 million compared to cash paid for acquisitions of $3.4 million during the nine months ended September 30, 2010. On January 14, 2011 the Company acquired approximately 80% of the common stock of Oxford Outcomes Limited, a leading international health outcomes consultancy business, headquartered in Oxford, United Kingdom for an initial cash consideration of £17.8 million ($27.7 million). Cash acquired on the acquisition of Oxford amount to £4.0 million ($6.3 million).  Further consideration of up to £6.5 million ($10.2 million) may become payable during the period to 31 March 2012 if certain performance milestones are achieved. In July 2011 the Company paid £3.3 million ($5.2 million) in respect of the first element of this additional consideration. £3.2 million ($5.0 million) was accrued at September 30, 2011 in respect of the remaining performance milestones.  In addition, the acquisition agreement provided for certain working capital targets to be achieved by Oxford Outcomes Limited on completion.  In May 2011 the Company paid an additional £3.3 million ($5.5 million) on completion of this review.

On January 14, 2011 a put and call option was also agreed between the Company and the selling shareholders for the acquisition of the remaining common stock of Oxford Outcomes Limited during the year ended December 31, 2011 for cash consideration of £3.8 million ($6.0 million).  Further consideration of up to £1.5 million ($2.3 million) relating to this remaining common stock may become payable during the period to March 31, 2012 if certain performance milestones are achieved.  £3.8 million ($6.0 million) was accrued at September 30, 2011 in respect of the additional consideration payable relating to this option and a further £1.5 million ($2.3 million) was accrued relating to the potential additional consideration payable in respect of the performance milestones.  On October 20, 2011 this option was exercised and £3.8 million ($6.0 million) was paid by the Company to the selling shareholders together with a further £0.7 million ($1.1 million) in respect of the first element of amounts due in respect of the performance milestones.

26

On July 14, 2011 the Company acquired 100% of the common stock of Firecrest Clinical Limited (“Firecrest”), a market leading provider of technology solutions that boost investigator site performance and study management, for an initial cash consideration of €17.0 million ($24.4 million).  Cash acquired on the acquisition of Firecrest amounted to $2.0 million.  Further consideration of up to €33.0 million ($44.9 million) may become payable if certain performance milestones are achieved in the period to 30 June 2013.  At September 30, 2011 the Company has accrued €32.7 million ($44.4 million) in relation to these performance milestones.

On May 17, 2010 the Company acquired Timaq Medical Imaging, a European provider of advanced imaging services to the pharmaceutical and biotechnology industry, located in Zurich, Switzerland for an initial cash consideration of CHF 1.3 million ($1.2 million).  Certain performance milestones were built into the acquisition agreement requiring potential additional consideration of up to CHF 2.9 million ($3.1 million) if these milestones are achieved during the years ended 31 December 2010 to 31 December 2013. On 31 December 2010 CHF 0.3 million ($0.3 million) was paid to the former shareholders in respect of certain milestones for the year ended 31 December 2010.  CHF 2.6 million ($2.9 million) remains accrued in relation to the remaining milestones at 30 September 2011.

On February 11, 2008, the Company acquired 100% of the common stock of Healthcare Discoveries Inc. for an initial cash consideration of $11.1 million, excluding costs of acquisition.  Healthcare Discoveries, located in San Antonio, Texas, is engaged in the provision of Phase I clinical trial management services.  Certain performance milestones were built into the acquisition agreement requiring payment of additional consideration of up to $10.0 million if these milestones were achieved during the year ended December 31, 2008.  On September 3, 2010, $2.2 million was paid to the former shareholders of Healthcare Discoveries Inc. in full and final settlement of the outstanding consideration payable.

Net cash provided by financing activities during the nine months ended September 30, 2011 amounted to $3.4 million compared with net cash provided by financing activities of $13.7 million for the nine months ended September 30, 2010. Net cash provided by financing activities in both periods arose primarily from the exercise of stock options.

As a result of these cash flows, cash and cash equivalents decreased by $128.9 million during the nine months ended September 30, 2011 compared to an increase of $86.5 million during the nine months ended September 30, 2010.

On July 20, 2011 the Company agreed a three year committed multi currency revolving credit facility for $150.0 million with Citibank, JP Morgan, Ulster Bank, Deutsche Bank and Barclays Bank. Each bank subject to the agreement has committed an equal amount of $30 million to the facility, with equal terms and conditions in place with all institutions. The facility bears interest at LIBOR plus a margin and is secured by certain composite guarantees, indemnities and pledges in favour of the banks. This facility replaced all facilities previously in place with Bank of Ireland, AIB, Citibank and JP Morgan.

6. Stock 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 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 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 may grant options to officers and other employees of the Company or its subsidiaries for the purchase of ordinary shares.  Each grant of an option under the 2003 Share Option Plan will be evidenced by a stock option agreement between the employee and the Company. The exercise price will be specified in each Stock Option Agreement.

An aggregate of 6.0 million ordinary shares have been reserved under the 2003 Share Option Plan; and, in no event will the number of ordinary shares that may be issued pursuant to options awarded under the 2003 Share Option 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 determines otherwise. Further, the maximum number of ordinary shares with respect to which options may be granted under the 2003 Share Option Plan during any calendar year to any employee shall be 400,000 ordinary shares.  No options can be granted after January 17, 2013.

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 September 30, 2011 is eight years.

The Company has granted options with fair values ranging from $3.68 to $13.93 per option or a weighted average fair value of $7.15 per option.  The Company issues new ordinary shares for all options exercised.

The total intrinsic value of options exercised during the nine months ended September 30, 2011 was $1.5 million (September 30, 2010: $11.4 million).

The following table summarizes the movement in non-vested share options during the nine months ended September 30, 2011:

	Options Outstanding Number of Shares			Weighted Average Exercise Price		Weighted Average Fair Value
Non vested outstanding at December 31, 2010		2,673,674		$	24.76	$	9.48
Granted		809,449		$	20.29	$	8.53

Forfeited		(246,281	)	$	25.25	$	9.72
Non vested outstanding at September 30, 2011		2,429,305		$	23.75	$	9.28

Stock Option Fair Values and Assumptions

The weighted average fair value of options granted during the period ended September 30, 2011 and September 30, 2010 was calculated using the Black-Scholes option pricing model.  The weighted average fair values and assumptions used were as follows:

	Nine Months Ended
	September 30,		September 30,
	2011		2010
Weighted average fair value	$	8.53	$	9.15
Assumptions:
Expected volatility		45%		45%
Dividend yield		0%		0%
Risk-free interest rate		1.5% - 2.3%		1.7%
Expected life	5 years		4.05 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

The Company has awarded restricted Share Units (“RSU’s”) to certain key executives of the Group.  Details of RSU’s granted during the nine months ended September 30, 2011 were as follows:

10,000	June 7, 2011	June 7, 2014	$24.60

The Company also awarded RSU’s in prior periods.  On August 7, 2008 the Company awarded 6,280 RSU’s to certain key employees of the Group.  These RSU’s vested over periods ranging from February 26, 2009 to February 26, 2011.  The market value of the Company’s ordinary shares on date of award was $41.95.  On August 16, 2010 the Company issued 2,512 ordinary shares relating to certain of these RSU awards.  On May 20, 2011 the Company issued a further 3,768 ordinary shares relating to the remaining RSU awards.

The following table summarizes the movement in non-vested RSU’s during the nine months ended September 30, 2011:

Segment Information

7. Segment Information

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

The Company operates predominantly in the contract clinical research industry providing a broad range of clinical research and integrated product development services on a global basis for the pharmaceutical and biotechnology industries. Historically, the Company organized, operated and assessed its business in two segments, the clinical research segment and the central laboratory segment, which includes the Company’s central laboratories located in Dublin, New York, India, Singapore and China. During the year ended December 31, 2009 management determined that its clinical research and central laboratory businesses operate in the same clinical research market, have a similar customer profile, are subject to the same regulatory environment, support the development of new clinical therapies and are so economically similar, reporting their results on an aggregated basis would be more useful to users of the Company’s financial statements. In addition, the central laboratory division did not reach the thresholds of net revenue, income from operations and total assets as a requirement for being reported as a separate segment.  Accordingly, the Company consolidated and reclassified the results of the former central laboratory segment into the clinical research segment for the three and nine months ended September 30, 2010.

During the year ended December 31, 2010 the Company incurred losses in its central laboratory business, which in accordance with FASB ASC 280-10 Disclosures about Segments of an Enterprises and Related Information requires it to be reported as a separate segment.  Accordingly the Company has disclosed two reportable segments for the three and nine months ended September 30, 2011.  The Company has reclassified the results of the central laboratory segment from the clinical research segment for three and nine months ended September 30, 2011.

The Company's areas of operation outside of Ireland principally include the United States, United Kingdom, France, Germany, Italy, Spain, The Netherlands, Sweden, Finland, Switzerland, Poland, Czech Republic, Lithuania, Latvia, Russia, Ukraine, Hungary, Israel, Romania, Canada, Mexico, Brazil, Colombia, Argentina, Chile, Peru, India, China, Hong Kong, South Korea, Japan, Thailand, Taiwan, Singapore, The Philippines, Australia, New Zealand, and South Africa. Segment information as at September 30, 2011 and December 31, 2010 and for the three and nine months ended September 30, 2011 and September 30, 2010 is as follows:

During the three months ended March 31, 2011 the Company commenced a review of its operations to improve resource utilization within the business and better align resources to current and future growth opportunities of the business.  This review resulted in the adoption of an initial restructuring plan (the “Q1 Restructuring Plan”), which resulted in the closure of the Company’s facility in Edinburgh, United Kingdom and resource rationalizations in certain of the more mature markets in which it operates.  A restructuring charge of $5.0 million in respect of this plan was recognized during the three months ended March 31, 2011, $1.0 million in respect of lease termination and exit costs associated with the closure of the Edinburgh facility and $4.0 million in respect of workforce reductions. $3.5 million of costs recognised under the Q1 Restructuring Plan related to the clinical research segment, while $1.5 million related to our central laboratory business.  During the three months ended September 30, 2011 the Company implemented a further restructuring plan (the “Q3 Restructuring Plan”) which resulted in the relocation of the Company’s facility in Maryland, USA; and further resource rationalizations.  A restructuring charge of $4.8 million was recognized during the three months ended September 30, 2011 in respect of this plan, $0.9 million in respect of lease termination and exit costs associated with the closure of the existing Maryland facility and $3.9 million in respect of workforce reductions.  All costs recognised under the Q3 Restructuring Plan related to the clinical research segment.

The Company does not believe that the outcome of any examination will have a material impact on its financial statements.

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				Nine Months Ended
	September 30,		September 30,		September 30,		September 30,
	2011		2010		2011		2010

Effect of dilutive share options outstanding		591,035		803,358		714,650		999,281
Weighted average number of ordinary shares for diluted net income per ordinary share		61,063,020		60,743,403		61,096,464		60,576,058

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, 2010. Operating results for the nine months ended September 30, 2011 are not necessarily indicative of the results that may be expected for the fiscal period ending December 31, 2011.
