Promises offered to the customer are not distinct within the context of the contract. We have concluded that ICON is the contract principal in respect of both direct services and in the use of third parties (principally investigator services) that support the clinical research project. The transaction price is determined by reference to the contract or change order value (total service revenue and pass-through/ reimbursable expenses) adjusted to reflect a realizable contract value. Revenue is recognized as the single performance obligation is satisfied. The progress towards completion for clinical service contracts is measured based on an input measure being total project costs incurred (inclusive of third party costs) at each reporting period as a percentage of forecasted total project costs.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Contracting services revenue&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company has availed of the practical expedient which results in recognition of revenue on a right to invoice basis. Application of the practical expedient reflects the right to consideration from the customer in an amount that corresponds directly with the value to the customer of the performance completion to date. This reflects hours performed by contract staff. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Consulting services revenue&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;We have concluded that our consulting services contracts represent a single performance obligation satisfied over time. The transaction price is determined by reference to contract or change order value. Revenue is recognized as the performance obligation is satisfied. The progress towards completion for consulting contracts is measured based on total project inputs (time) at each reporting period as a percentage of forecasted total project inputs.  &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Laboratory services revenue&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the products or services are transferred to the customer. Revenue for laboratory services is measured as the amount of consideration we expect to receive in exchange for transferring products or services. Where contracts with customers contain multiple performance obligations, the transaction price is allocated to each performance obligation based on the estimated relative selling price of the promised good or service. Service revenue is recognized over time as the services are delivered to the customer based on the extent of progress towards completion of the performance obligation. The determination of the methodology to measure progress requires judgment and is based on the nature of services provided. This requires an assessment of the transfer of value to the customer. The right to invoice measure of progress is generally related to rate per unit contracts, as the extent of progress towards completion is measured based on discrete service or time-based increments, such as samples tested or labor hours incurred. Revenue is recorded in the amount invoiced since that amounts corresponds to the value of the Company's performance and the transfer of value to the customer.   &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Data services revenue&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company provides data reports and analytics to customers based on agreed-upon specifications, including the timing of delivery, which is typically either weekly, monthly, or quarterly. If a customer requests more than one type of data report or series of data reports within a contract, each distinct type of data report is a separate performance obligation. The contracts provide for the Company to be compensated for the value of each deliverable. The transaction price is determined using list prices, discount agreements, if any, and negotiations with the customers, and generally includes any out-of-pocket expenses. Typically, the Company bills in advance of services being provided with the amount being recorded as unearned revenue.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;When multiple performance obligations exist, the transaction price is allocated to performance obligations on a relative standalone selling price basis. In cases where the Company contracts to provide a series of data reports, or in some cases data, the Company recognizes revenue over time using the &#x201c;units delivered&#x201d; output method as the data or reports are delivered. Expense reimbursements are recorded to revenue as the expenses are incurred as they relate directly to the services performed.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Commissions&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Incremental costs of obtaining a contract are recognized as an asset on the Condensed Consolidated Balance Sheet in respect of those contracts that exceed one year. Where commission costs relate to contracts that are less than one year, the practical expedient is applied as the amortization period of the asset which would arise on deferral would be one year or less.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:15pt;text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:700;line-height:120%"&gt;Business Combinations&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:15pt;text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The cost of a business combination is measured as the aggregate of the fair values at the date of exchange of assets given, liabilities incurred or assumed and equity instruments issued in exchange for control. Where a business combination agreement provides for an adjustment to the cost of the acquisition which is contingent upon future events, the amount of the estimated adjustment is recognized at the acquisition date at the fair value of the contingent consideration. Any changes to this estimate outside the measurement period will depend on the classification of the contingent consideration. If the contingent consideration is classified as equity it shall not be re-measured and the settlement shall be accounted for within equity. If the contingent consideration is classified as a liability any adjustments will be accounted for through the Consolidated Statement of Operations or Other Comprehensive Income depending on whether the liability is considered a financial instrument.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The assets, liabilities and contingent liabilities of businesses acquired are measured at their fair values at the date of acquisition. In the case of a business combination which is completed in stages, the fair values of the identifiable assets, liabilities and contingent liabilities are determined at the date of each exchange transaction. When the initial accounting for a business combination is determined provisionally, any subsequent adjustments to the provisional values allocated to the identifiable assets, liabilities and contingent liabilities are made within twelve months of the acquisition date and presented as adjustments to goodwill in the reporting period in which the adjustments are determined.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company allocates a share of net income to the noncontrolling interest holders based on percentage ownership. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:15pt;text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:700;line-height:120%"&gt;Intangible Assets&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:15pt;text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Intangible assets are amortized on a straight line basis over their estimated useful life.&lt;/span&gt;&lt;/div&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

The transaction price is determined by reference to the contract or change order value (total service revenue and pass-through/ reimbursable expenses) adjusted to reflect a realizable contract value. Revenue is recognized as the single performance obligation is satisfied. The progress towards completion for clinical service contracts is measured based on an input measure being total project costs incurred (inclusive of third party costs) at each reporting period as a percentage of forecasted total project costs.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Contracting services revenue&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company has availed of the practical expedient which results in recognition of revenue on a right to invoice basis. Application of the practical expedient reflects the right to consideration from the customer in an amount that corresponds directly with the value to the customer of the performance completion to date. This reflects hours performed by contract staff. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Consulting services revenue&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;We have concluded that our consulting services contracts represent a single performance obligation satisfied over time. The transaction price is determined by reference to contract or change order value. Revenue is recognized as the performance obligation is satisfied. The progress towards completion for consulting contracts is measured based on total project inputs (time) at each reporting period as a percentage of forecasted total project inputs.  &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Laboratory services revenue&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the products or services are transferred to the customer. Revenue for laboratory services is measured as the amount of consideration we expect to receive in exchange for transferring products or services. Where contracts with customers contain multiple performance obligations, the transaction price is allocated to each performance obligation based on the estimated relative selling price of the promised good or service. Service revenue is recognized over time as the services are delivered to the customer based on the extent of progress towards completion of the performance obligation. The determination of the methodology to measure progress requires judgment and is based on the nature of services provided. This requires an assessment of the transfer of value to the customer. The right to invoice measure of progress is generally related to rate per unit contracts, as the extent of progress towards completion is measured based on discrete service or time-based increments, such as samples tested or labor hours incurred. Revenue is recorded in the amount invoiced since that amounts corresponds to the value of the Company's performance and the transfer of value to the customer.   &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Data services revenue&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company provides data reports and analytics to customers based on agreed-upon specifications, including the timing of delivery, which is typically either weekly, monthly, or quarterly. If a customer requests more than one type of data report or series of data reports within a contract, each distinct type of data report is a separate performance obligation. The contracts provide for the Company to be compensated for the value of each deliverable. The transaction price is determined using list prices, discount agreements, if any, and negotiations with the customers, and generally includes any out-of-pocket expenses. Typically, the Company bills in advance of services being provided with the amount being recorded as unearned revenue.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;When multiple performance obligations exist, the transaction price is allocated to performance obligations on a relative standalone selling price basis. In cases where the Company contracts to provide a series of data reports, or in some cases data, the Company recognizes revenue over time using the &#x201c;units delivered&#x201d; output method as the data or reports are delivered. Expense reimbursements are recorded to revenue as the expenses are incurred as they relate directly to the services performed.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Commissions&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Incremental costs of obtaining a contract are recognized as an asset on the Condensed Consolidated Balance Sheet in respect of those contracts that exceed one year. Where commission costs relate to contracts that are less than one year, the practical expedient is applied as the amortization period of the asset which would arise on deferral would be one year or less.&lt;/span&gt;&lt;/div&gt;</us-gaap:RevenueFromContractWithCustomerPolicyTextBlock>

Where a business combination agreement provides for an adjustment to the cost of the acquisition which is contingent upon future events, the amount of the estimated adjustment is recognized at the acquisition date at the fair value of the contingent consideration. Any changes to this estimate outside the measurement period will depend on the classification of the contingent consideration. If the contingent consideration is classified as equity it shall not be re-measured and the settlement shall be accounted for within equity. If the contingent consideration is classified as a liability any adjustments will be accounted for through the Consolidated Statement of Operations or Other Comprehensive Income depending on whether the liability is considered a financial instrument.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The assets, liabilities and contingent liabilities of businesses acquired are measured at their fair values at the date of acquisition. In the case of a business combination which is completed in stages, the fair values of the identifiable assets, liabilities and contingent liabilities are determined at the date of each exchange transaction. When the initial accounting for a business combination is determined provisionally, any subsequent adjustments to the provisional values allocated to the identifiable assets, liabilities and contingent liabilities are made within twelve months of the acquisition date and presented as adjustments to goodwill in the reporting period in which the adjustments are determined.&lt;/span&gt;&lt;/div&gt;The Company allocates a share of net income to the noncontrolling interest holders based on percentage ownership.</us-gaap:BusinessCombinationsPolicy>

satisfaction of performance obligations and the invoicing and collection of amounts related to our contracts with customers. We record assets for amounts related to performance obligations that are satisfied but not yet billed and/or collected. These assets are recorded as unbilled services and therefore contract assets rather than accounts receivables when receipt of the consideration is conditional on something other than the passage of time. Liabilities are recorded for amounts that are collected in advance of the satisfaction of performance obligations or billed in advance of the revenue being earned.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Unbilled services/revenue balances arise where invoicing or billing is based on the timing of agreed milestones related to service contracts for clinical research. Contractual billing arrangements in respect of certain reimbursable expenses (principally investigators) require billing by the investigator to the Company prior to billing by the Company to the customer. As there is no contractual right to set-off between unbilled services (contract assets) and unearned revenue (contract liabilities), each are separately presented gross on the Condensed Consolidated Balance Sheet. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Unbilled services as at March&#160;31, 2022 increased by $51.4 million compared to December&#160;31, 2021. Unearned revenue decreased by $23.0 million over the same period resulting in an increase of $74.4 million in the net balance of unbilled services and unearned revenue or payments on account between December&#160;31, 2021 and March&#160;31, 2022. These fluctuations are primarily due to timing of payments and invoicing related to the Group's clinical trial management contracts. Billings and payments are established by contractual provisions including predetermined payment schedules which may or may not correspond to the timing of the transfer of control of the Company's services under the contract. Unbilled services arise from long-term contracts when a cost-based input method of revenue recognition is applied and revenue recognized exceeds the amount billed to the customer.&lt;/span&gt;&lt;/div&gt;As of March&#160;31, 2022 approximately $13.6 billion (March&#160;31, 2021: $6.5 billion) of revenue is expected to be recognized in the future in respect of unsatisfied performance obligations. The Company expects to recognize revenue on approximately 49% of the unsatisfied performance obligation over the next 12 months, with the remainder recognized thereafter over the duration of the customer contracts.</us-gaap:RevenueFromContractWithCustomerTextBlock>

Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. A three-level fair value hierarchy that prioritizes the inputs used to measure fair value is described below. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-align:justify;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:14.85pt"&gt;Level 1 &#x2014; Quoted prices in active markets for identical assets or liabilities.&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-align:justify;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:14.85pt"&gt;Level 2 &#x2014; Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-align:justify;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:14.85pt"&gt;Level 3 &#x2014; Unobservable inputs that are supported by little or no market activity.

The Company determined that the interests in funds at March&#160;31, 2022 and December&#160;31, 2021 meet the definition of equity securities without readily determinable fair values. The Company concluded that the interests held at March&#160;31, 2022 and December&#160;31, 2021 qualify for the Net Asset Value (NAV) practical expedient in ASC 820 'Fair value measurements and disclosures'. Any increases or decreases in fair value are recognized in net income in the period. These are therefore measured at Level 3 of the fair value hierarchy. The value of these investments were $26.0 million at March&#160;31, 2022 and $22.6 million at December&#160;31, 2021.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Non-recurring Fair Value Measurements &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Certain assets and liabilities are carried on the accompanying Condensed Consolidated Balance Sheet at cost and are not re-measured to fair value on a recurring basis. These assets include finite-lived intangible assets that are tested for impairment when a triggering event occurs and goodwill and identifiable indefinite-lived intangible assets that are tested for impairment annually or when a triggering event occurs. As of March&#160;31, 2022, assets carried on the balance sheet and not re-measured to fair value on a recurring basis totaled approximately $13,620.6 million and are identified as Level 3 assets. These assets are comprised of goodwill of $9,028.0 million and identifiable intangible assets, net of $4,592.6 million.

"Senior Secured Credit Facilities"), which consists of a senior secured term loan and a revolving credit facility, and the senior secured notes (the "Senior Secured Notes").&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span

style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;In conjunction with the completion of the Merger agreement, on July 1, 2021, ICON entered into a credit agreement providing for a senior secured term loan facility of $5,515&#160;million and a senior secured revolving loan facility in an initial aggregate principal amount of $300&#160;million (the "Senior Secured Credit Facilities"). &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div

loan facility amortize in equal quarterly installments in an amount equal to 1.00% per annum of the principal amount, with the remaining balance due at final maturity. The interest rate margin applicable to borrowings under the senior secured term loan facility is LIBOR plus an applicable margin of 2.50%, in each case, with a step down of 0.25% if the first lien net leverage ratio is equal to or less than 4.00 to 1.00. On November&#160;10, 2021, the Company achieved a net leverage ratio of less than 4 times and the margin applicable to the senior secured term loan was reduced by 0.25%. The senior secured term loan facility is subject to a LIBOR floor of 0.50%.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:112%"&gt;The interest rate margin applicable to borrowings under the revolving loan facility will be, at the option of the borrower, either (i) the applicable base rate plus an applicable margin of 1.00%, 0.60% or 0.25% based on ICON&#x2019;s current corporate family rating assigned by S&amp;amp;P of BB- (or lower), BB or BB+ (or higher), respectively, or (ii) LIBOR (or an alternative reference rate) plus an applicable margin of 2.00%, 1.60% or 1.25% based on ICON&#x2019;s current corporate family rating assigned by S&amp;amp;P of BB- (or lower), BB or BB+ (or higher), respectively. In addition, lenders of under the revolving loan facility are entitled to commitment fees as a percentage of the applicable margin at the time of drawing and utilization fees dependent on the proportion of the facility drawn.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Borrowers&#x2019; (as defined in the credit agreement) obligations under the Senior Secured Credit Facilities are guaranteed by ICON and the subsidiary guarantors. The Senior Secured Credit Facilities are secured by a lien on substantially all of ICON&#x2019;s, the Borrowers&#x2019; and each of the subsidiary guarantor&#x2019;s assets (subject to certain exceptions), and the Senior Secured Credit Facilities will have a first-priority lien on such assets, which will rank pari passu with the lien securing the Senior Secured Notes (see below), subject to other permitted liens. Our long-term debt arrangements contain customary restrictive covenants and, as of March&#160;31, 2022, we were in compliance with our restrictive covenants in all material respects.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;On March&#160;31, 2022 the Company repaid $300.0&#160;million of the senior secured term loan facility and made a quarterly interest payment of $35.1&#160;million. These repayments resulted in an additional charge associated with previously capitalized fees of $3.2&#160;million. On December 29, 2021, the Company repaid $500.0&#160;million of the senior secured term loan facility.

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 through internal growth, together with a number of strategic acquisitions to enhance its expertise and capabilities in certain areas of the clinical development process.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The Company determines and presents operating segments based on the information that is internally provided to the chief operating decision maker, the (&#x2018;CODM&#x2019;) in accordance with ASC 280 &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;'Segment Reporting'&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;.

ICON Ireland enters into the majority of the Company&#x2019;s customer contracts. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;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 integration of entities acquired through the Merger into this global network and global transfer pricing model remains ongoing.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;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.
