PRA HEALTH SCIENCES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

(UNAUDITED)

(1) Basis of Presentation

The Company

PRA Health Sciences, Inc. and its subsidiaries, or the Company, is a full-service global contract research organization providing a broad range of product development and data solution services to pharmaceutical and biotechnology companies around the world. The Company’s integrated services include data management, statistical analysis, clinical trial management, and regulatory and drug development consulting.

Unaudited Interim Financial Information

The interim consolidated condensed financial statements include the accounts of the Company and variable interest entities where the Company is the primary beneficiary. These financial statements are prepared in conformity with U.S. generally accepted accounting principles, or GAAP, and are unaudited. In the opinion of the Company’s management, all adjustments of a normal recurring nature necessary for a fair presentation have been reflected. Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been omitted. The accompanying interim consolidated condensed financial statements and related notes should be read in conjunction with the Company’s consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

The preparation of the interim consolidated condensed financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim consolidated condensed financial statements and the reported amounts of revenues and claims and expenses during the reporting period. Actual results could differ from those estimates.

Recently Implemented Accounting Pronouncements

On January 1, 2019, the Company adopted Accounting Standards Codification, or ASC, Topic 842, ~~“Leases” (“~~“Leases,” or ASC ~~842”)~~842, using the revised modified retrospective approach provided by ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements.” The revised modified retrospective approach recognizes the effects of initially applying the new leases standard as a cumulative effect adjustment to retained earnings as of the adoption date. Under this election, the provisions of ASC 840 apply to the accounting and disclosures for lease arrangements in the comparative periods in the Company's financial statements.

The adoption of ASC 842 resulted in the recognition of lease liabilities of $211.7 million (recorded as $31.9 million in short-term lease liabilities and $179.8 million in long-term lease liabilities) and $187.1 million of lease right-of-use, ~~("ROU")~~or ROU, assets as of January 1, 2019. Upon adoption of ASC 842, the Company had lease obligations associated with deferred rent, lease loss liabilities, above market lease liabilities, and tenant improvement allowances, totaling $25.7 million, that were reclassified to the lease right-to-use assets. The Company had prepaid rent balances, totaling $1.1 million, that were reclassified toas a reduction of the current portion of operating lease liabilities. The adoption of ASC 842 did not impact the consolidated condensed statement of operations for the ~~three~~nine months ended ~~March 31,~~September 30, 2019, consolidated condensed statement of cash flows, or earnings per share. See ~~Note~~"Note 2 ~~"Significant~~- Significant Accounting Policies" for further disclosures regarding the adoption of ASC 842.

In August 2017, the Financial Accounting Standards Board, or FASB, issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities," in order to simplify certain aspects of hedge accounting and improve disclosures of hedging arrangements. ASU No. 2017-12 eliminates the need to separately measure and report hedge ineffectiveness and generally requires the entire change in fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Entities must apply the amendments to cash flow and net investment hedge relationships that exist on the date of adoption using a modified retrospective approach. The presentation and disclosure requirements must be applied prospectively. The Company adopted this standard effective January 1, 2019 and the application of ASU No. 2017-12 did not have a material impact on the Company's consolidated condensed financial statements.

In February 2018, the FASB issued ASU No. 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects

resulting from the Tax Cuts and Jobs Act of 2017, or the Act. The amendments in this update also require entities to disclose their accounting policy for releasing income tax effects from accumulated other comprehensive income. The Company adopted this standard effective January 1, 2019 and the application of ASU No. 2018-02 resulted in a reclassification of $1.4 million from accumulated other comprehensive loss to retained earnings for the stranded tax effects resulting from the Act.

In October 2018, the FASB issued ASU No. 2018-16, "Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes," which amends ASC 815, Derivatives and Hedging. This ASU adds the OIS rate based on SOFR to the list of permissible benchmark rates for hedge accounting purposes. The Company adopted ASU No. 2018-16 concurrent with adoption of ASU No. 2017-12, on January 1, 2019, and the application of ASU No. 2018-16 did not have a material impact on the Company’s consolidated condensed financial statements.

Recently Issued Accounting Pronouncements

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other: Simplifying the Test for Goodwill Impairment,” in order to simplify the subsequent measurement of goodwill by eliminating the Step 2 goodwill impairment test. Under the amendments in this ASU, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity will then recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The ~~amendments to ASU No. 2017-04 are~~guidance is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The adoption of ASU No. 2017-04 is not expected to have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract," in order to expand on the FASB's guidance of capitalized costs incurred in a cloud computing arrangement. The amendments in this update require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The ~~amendments to ASU No. 2018-15 are~~guidance is effective for the reporting period beginning after December 15, 2019, and interim periods therein, with early adoption permitted. The adoption of ASU No. 2018-15 is not expected to have a material impact on the Company's consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The provisions of ASU 2016-13 modify the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology and require consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance is effective for the reporting period beginning after December 15, 2019, and the interim periods therein. The adoption of ASU 2016-13 is not expected to have a material impact on the Company’s consolidated financial statements.

Cash, Cash Equivalents, and Restricted Cash

The Company receives cash advances from its customers to be used for the payment of investigator fees and other pass-through expenses. The terms of certain customer contracts require that such advances be maintained in separate escrow accounts; thus, these accounts are not commingled with the Company’s cash and cash equivalents. These accounts are presented separately in the consolidated condensed balance sheets as restricted cash.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the consolidated condensed balance sheets that sum to the total of the same amounts shown in the consolidated condensed statements of cash flows (in thousands):


	March 31,				December 31,				September 30,				December 31,
	2019		2018		2018		2017		2019		2018		2018		2017

(2) Significant Accounting Policies

Significant accounting policies are detailed in "Note 2: Significant Accounting Policies" of the Annual Report on Form 10-K for the year ended December 31, 2018. Significant changes to the Company's accounting policies as a result of adopting ASC 842 are discussed below:

On January 1, 2019, the Company adopted ASC 842 using the revised modified retrospective approach. The revised modified retrospective approach recognizes the effects of initially applying the new leases standard as a cumulative effect adjustment to retained earnings as of the adoption date. Under this election, the provisions of ASC 840 apply to the accounting

and disclosures for lease arrangements in the comparative periods in an entity’s financial statements. In addition, the Company elected the package of practical expedients permitted under the transition guidance within ASC 842, in which the Company need not reassess (i) the historical lease classification, (ii) whether any expired or existing contract is or contains a lease, or (iii) the initial direct costs for any existing leases.

The Company’s material lease obligations are operating leases for office and other facilities in which the Company conducts business. The facility leases generally provide an initial lease term ranging from ~~five~~three to 20 years and include one or more optional extensions. The Company's leases have remaining lease terms of one year to 17 years. The leases typically include rent escalation clauses and for some markets the leases frequently include periodic market adjustments to the base rent over the term of the lease. In certain instances, the Company subleases space that has been exited or is no longer required. The Company’s sublease income is immaterial.

Upon the initial application of ASC 842 on January 1, 2019, ~~(the “transition date”),~~or the transition date, lease liabilities were measured by using the remaining minimum rental payments under ASC 840. The Company’s ASC 840 minimum rental payments include executory costs and rental payments that depend on an index or rate are calculated based on the rate in effect at the transition date. The lease liability is measured at the present value of future lease payments, discounted using the discount rate as of the transition date. In addition to recognizing the lease liability, the Company recognized a corresponding asset representing its right to use the underlying asset over the lease term, referred to as the lease ROU asset. The ROU asset is initially measured as the amount of lease liability, adjusted for any initial lease costs or lease payments made before or at the commencement of the lease, and reduced by any lease incentives and deferred rent. As of the transition date, the Company’s leases consisted of only operating leases and upon recognition of the lease liability and ROU assets, there was no adjustment to retained earnings.

All leases entered into after January 1, 2019 are accounted for under ASC 842. Under ASC 842, a contract is or contains a lease when (i) explicitly or implicitly identified assets have been deployed in the contract and (ii) the customer obtains substantially all of the economic benefits from the use of that underlying asset and directs how and for what purpose the asset is used during the term of the contract. The Company also considers whether its service arrangements include the right to control the use of an asset. The Company determines if an arrangement is a lease at inception of the contract, which is the date on which the terms of the contract are agreed to and the agreement creates enforceable rights and obligations. The commencement date of the lease is the date that the lessor makes an underlying asset available for use by a lessee.

At the lease commencement date, a lease liability is recognized based on the present value of the lease payments not yet paid, discounted using the discount rate for the lease at lease commencement. When readily determinable, the discount rate used to calculate the lease liability is the rate implicit in the lease. As the Company's leases typically do not provide an implicit rate, the Company uses its incremental borrowing rate based on the lease term and economic environment at the lease commencement date. The lease term used to calculate the lease liability includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. With limited exceptions, the nature of the Company's facility leases is such that there are not economic or other conditions that would indicate that it is reasonably certain at lease commencement that the Company will exercise options to extend the term.

The Company determines if its lease obligations are operating or finance leases at the lease commencement date and considers whether the lease grants an option to purchase the underlying asset that it is reasonably certain to exercise, the remaining economic life of the underlying asset, the present value of the sum of the remaining lease payments and any residual value guaranteed, and the nature of the asset.

The initial measurement of the lease liability is determined based on the future lease payments, which may include lease payments that depend on an index or a rate (such as the consumer price index or other market index). The Company initially measures payments based on an index or rate by using the applicable rate at lease commencement and subsequent changes in such rates are recognized as variable lease costs. Variable payments that do not depend on a rate or index are not included in the lease liability and are recognized as they are incurred. The Company’s contracts that include a lease component generally include additional services that are transferred to the lessee (e.g., common-area maintenance services), which are

nonlease components. Contracts typically also include other costs and fees that do not provide a separate service to the lessee, such as costs paid by the lessee to reimburse the lessor for administrative costs or payment for the lessor’s costs for property taxes, insurance related to the leased asset, and other lessor costs. The Company elected the practical expedient to account for the lease and nonlease components as a single lease component. At the lease commencement date, the Company recognizes a ROU asset representing its right to use the underlying asset over the lease term. If significant events, changes in circumstances, or other events indicate that the lease term has changed, the Company would reassess lease classification, remeasure the lease liability by using revised inputs as of the reassessment date, and adjust the ROU asset. These reassessment events are typically related to the exercise of optional renewals or significant new investments in leasehold improvements. The costs of services and costs related to reimbursements of the lessor’s cost are generally variable rent obligations, which are excluded from the

future lease payments included in the lease liability. For leases with a term of one year or less, (“or short-term ~~leases”),~~leases, the Company has elected to not recognize the lease liability for these arrangements and the lease payments are recognized in the consolidated statement of operations on a straight-line basis over the lease term.

The total expense for the operating lease liability is recognized on a straight-line basis over the lease term, beginning on the lease commencement date. The Company classifies the lease costs within operating expenses consistent with the classification policies for all other operating costs.

The components of lease expense were as follows for the three and nine months ended ~~March 31,~~September 30, 2019 (in thousands):


	Three Months Ended March 31, 2019			Three Months Ended September 30, 2019			Nine Months Ended September 30, 2019

2022	30,238
2023	24,235
Thereafter	90,978
Total lease payments	$	267,543

(3) Fair Value Measurements

The Company records certain assets and liabilities at fair value. 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:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — 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.

Level 3 — Unobservable inputs that are supported by little or no market activity. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

The carrying amount of financial instruments, including cash and cash equivalents, accounts receivable, unbilled services, contract assets, accounts payable and advanced billings, approximate fair value due to the short maturities of these instruments.

Recurring Fair Value Measurements

The following table summarizes the fair value of the Company’s financial ~~assets~~liabilities that are measured on a recurring basis as of ~~March 31,~~September 30, 2019 (in thousands):


	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total
Assets:
Liabilities:
Interest rate swaps	$	—	$	908	$	—	$	908	$	—	$	3,805	$	—	$	3,805
Total	$	—	$	908	$	—	$	908	$	—	$	3,805	$	—	$	3,805

Non-recurring Fair Value Measurements

Certain assets and liabilities are carried on the accompanying consolidated condensed balance sheets at cost and are not remeasured 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 on October 1 or when a triggering event occurs.

As of ~~March 31,~~September 30, 2019, assets carried on the balance sheet and not remeasured to fair value on a recurring basis ~~totaling~~totaled approximately ~~$2,188.9~~$2,133.8 million and are identified as Level 3 assets. These assets are comprised of goodwill of ~~$1,499.9~~$1,484.5 million and identifiable intangible assets, net of ~~$689.0~~$649.3 million.

Refer to ~~Note~~"Note 7 - Revolving Credit Facilities and Long-Term ~~Debt,~~Debt" for additional information regarding the fair value of long-term debt balances.

(4) Concentration of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents, accounts receivable, unbilled services, and derivatives. As of ~~March 31,~~September 30, 2019, substantially all of the Company’s cash and cash equivalents and derivatives were held in or invested with large financial institutions. Accounts receivable include amounts due from pharmaceutical and biotechnology companies. The Company establishes an allowance for potentially uncollectible receivables. In management’s opinion, there is no additional material credit risk beyond amounts provided for such losses.

There were no individual customers for which revenue was greater than 10% of consolidated revenue in the three and nine months ended ~~March 31,~~September 30, 2019 and 2018.

Accounts receivable and unbilled ~~receivables~~services from individual customers that were equal to or greater than 10% of consolidated accounts receivable and unbilled ~~receivables~~services at the respective dates were as follows:


	March 31,		December 31,		September 30,		December 31,
	2019		2018		2019		2018
Customer A	11.8	%	12.2	%	10.6	%	12.2	%
Customer B	*		11.4	%	15.5	%	11.4	%

* Less than 10%

(5) Accounts Receivable, Unbilled Services and Advanced Billings

Accounts receivable and unbilled services were as follows (in thousands):


	March 31,			December 31,			September 30,			December 31,
	2019			2018			2019			2018
Accounts receivable	$	463,256		$	437,001		$	557,077		$	437,001
Unbilled services	136,252			133,147			147,952			133,147
Total accounts receivable and unbilled services	599,508			570,148			705,029			570,148
Less allowance for doubtful accounts	(2,296		)	(2,049		)	(2,393		)	(2,049		)
Total accounts receivable and unbilled services, net	$	597,212		$	568,099		$	702,636		$	568,099

Unbilled services as of ~~March 31,~~September 30, 2019 and December 31, 2018 includes ~~$69.2~~$75.1 million and $66.6 million, respectively, of contract assets where the Company’s right to bill is conditioned on criteria other than the passage of time. Impairment losses on contract assets were immaterial in the three and nine months ended ~~March 31,~~September 30, 2019 and 2018.

Advanced billings were as follows (in thousands):

March 31, December 31,
2019 2018
Advanced billings $ 432,482
$ 441,357



	September 30,		December 31,
	2019		2018
Advanced billings	$	474,999	$	441,357

The ~~$8.9~~$33.6 million ~~decrease~~increase in advanced billings from December 31, 2018 to ~~March 31,~~September 30, 2019 was primarily due to the timing of customer payments. During the ~~three~~nine months ended ~~March 31,~~September 30, 2019 and 2018, the Company recognized revenue of ~~$261.1~~$398.4 million and ~~$230.5~~$382.5 million related to advanced billings recorded as of January 1, 2019 and ~~2018.~~2018, respectively.

Performance Obligations

Revenue recognized ~~for the three months ended March 31, 2019~~from reimbursable expenses and ~~2018 from~~ services completed in prior periods was ~~$26.5~~$14.8 million and ~~$3.9~~$65.2 million for the three and nine months ended September 30, 2019, respectively, and $24.4 million and $57.3 million for the three and nine months ended September 30, 2018, respectively. This primarily relates to adjustments attributable to changes in estimates such as estimated total contract costs, and from contract modifications on long-term fixed price contracts executed in the current period, which results in changes to the transaction price.

The Company does not disclose the value of the transaction price allocated to unsatisfied performance obligations on contracts that have an original contract term of less than one year. These contracts are short in duration and revenue recognition generally follows the delivery of the promised services. The total transaction price for the undelivered performance obligation

on contracts with an original initial contract term greater than one year is ~~$4.9~~$5.2 billion as of ~~March 31,~~September 30, 2019. This amount includes reimbursement revenue. The Company expects to recognize revenue over the remaining contract term of the individual projects, with contract terms generally ranging from one to five years.

(6) Goodwill and Intangible Assets

Goodwill

2016 Credit Facilities

~~The senior secured credit facilities, or 2016 Credit Facilities, provide senior secured financing up to $1,400.0 million, consisting of:~~

•~~a first lien term loan in an aggregate principal amount of up to $1,175.0 million; and~~

•~~revolving credit facilities, or the 2016 Revolver, in an aggregate principal amount of up to $225.0 million~~

As collateral for borrowings under the senior secured credit facilities, or 2016 Credit Facilities, the Company granted a pledge on primarily all of its assets, and the stock of wholly-owned U.S. restricted subsidiaries. The Company is subject to certain financial covenants, which require the Company to maintain certain debt-to-EBITDA and interest expense-to-EBITDA ratios. The 2016 Credit Facilities also contain covenants that, among other things, restrict the Company’s ability to create any liens, make investments and acquisitions, incur or guarantee additional indebtedness, enter into mergers or consolidations and other fundamental changes, conduct sales and other dispositions of property or assets, enter into sale-leaseback transactions or hedge agreements, prepay subordinated debt, pay dividends or make other payments in respect of capital stock, change the line of business, enter into transactions with affiliates, enter into burdensome agreements with negative pledge clauses, and make subsidiary distributions. After giving effect to the applicable restrictions on the payment of dividends under the 2016 Credit Facilities, subject to compliance with applicable law, as of ~~March 31,~~September 30, 2019 and December 31, 2018, all amounts in retained earnings were free of restriction and were available for the payment of dividends. The 2016 Credit Facilities also contain customary representations, warranties, affirmative covenants, and events of default. The variable interest rate is a rate equal to the London Interbank Offered Rate, or LIBOR, or the adjusted base rate, or ABR, at the election of the Company, plus a margin based on the ratio of total indebtedness to EBITDA. The margin ranges from 1.00% to 2.00%, in the case of LIBOR loans, and 0.00% to 1.00%, in the case of ABR loans. The Company has the option of 1, 2, 3 or 6 month base interest rates. For the ~~three~~nine months ended ~~March 31,~~September 30, 2019, the weighted average interest rate on the first lien term loan was ~~3.96%~~3.75%.

On September 3, 2019, the Company received the proceeds from a $300.0 million incremental term loan under the 2016 Credit Facilities, or the Incremental Borrowing. The Incremental Borrowing was used to fund the share repurchase which is discussed further in "Note 8 - Stockholders' Equity". In accordance with the guidance in ASC 470-50, "Debt - Modifications and Extinguishments," the Incremental Borrowing was accounted for as a debt modification. The Incremental Borrowing resulted in a $1.9 million loss on modification of debt, which consists of third-party fees associated with the transaction. The Company's voluntary term loan prepayments made during 2018 and 2019 fully satisfied all required quarterly principal payments through maturity.

2016 Revolver

The revolving credit facility under the 2016 Credit Facilities, or 2016 Revolver, provides for $225.0 million of potential borrowings and expires on December 6, 2021. The interest rate on the 2016 Revolver is based on the LIBOR with a 0% LIBOR floor or ABR, at the election of the Company, plus an applicable margin, based on the leverage ratio of the Company. The Company, at its discretion, may elect interest periods of 1, 2, 3 or 6 months. The Company is required to pay to the lenders a commitment fee for unused commitments of 0.2% to 0.4% based on the Company’s debt-to-EBITDA ratio. At ~~March 31,~~September 30, 2019 and December 31, 2018, the Company had no0 outstanding borrowings under the 2016 Revolver. In addition, at ~~March 31,~~September 30, 2019 and December 31, 2018, the Company had ~~$5.5~~$5.2 million and $5.4 million, respectively, in letters of credit outstanding, which are secured by the 2016 Revolver.

Accounts Receivable Financing Agreement

The Company had $~~170.0~~200.0 million and $170.0 million outstanding on its accounts receivable financing agreement as of ~~March 31,~~September 30, 2019 and December 31, ~~2018.~~2018, respectively.

Loans under the accounts receivable financing agreement accrue interest at either a reserve-adjusted LIBOR or a base rate, plus 1.25%. The Company may prepay loans upon one business day's prior notice and may terminate the accounts receivable financing agreement with 15 days’ prior notice. For the ~~three~~nine months ended ~~March 31,~~September 30, 2019, the weighted average interest rate on the accounts receivable financing agreement was ~~4.00%~~3.86%.

The accounts receivable financing agreement contains various customary representations and warranties and covenants, and default provisions that provide for the termination and acceleration of the commitments and loans under the agreement in circumstances including, but not limited to, failure to make payments when due, breach of representations, warranties or covenants, certain insolvency events or failure to maintain the security interest in the trade receivables, and defaults under other material indebtedness.

At ~~March 31, 2019 and~~ December 31, 2018, there was $30.0 million of remaining capacity available under the accounts receivable financing agreement. At September 30, 2019, there was no remaining capacity available under the accounts receivable financing agreement.

Fair Value of Debt

The estimated fair value of the Company’s debt and outstanding borrowings under its revolving credit facilities was $1,390.0 million and $1,084.2 million at ~~March 31,~~September 30, 2019 and December 31, ~~2018.~~2018, respectively. The fair values of the term loans, borrowings under credit facilities, and accounts receivable financing agreement were determined based on Level 2 inputs, which are primarily based on rates at which the debt is traded among financial institutions adjusted for the Company's credit standing.

(8) Stockholders’ Equity

Authorized Shares

The Company is authorized to issue up to ~~one billion~~1000000000 shares of common stock, with a par value of $0.01. The Company is authorized to issue up to ~~one hundred million~~100 shares of preferred stock, with a par value of $0.01.

Share Repurchase Program

On August 30, 2019, the Company's Board of Directors, or the Board, approved a share repurchase program, or the Repurchase Program, authorizing the repurchase of up to $500.0 million of the Company's common stock in open market purchases, privately-negotiated transactions, secondary offerings, block trades or otherwise in accordance with all applicable securities laws and regulations, including through Rule 10b5-1 trading plans and pursuant to Rule 10b-18 under the Securities Exchange Act of 1934, as amended, or the Exchange Act. The Repurchase Program does not obligate the Company to repurchase any particular amount of its common stock, and it may be modified, suspended or terminated at any time at the Board's discretion. The Repurchase Program expires on December 31, 2021.

On September 6, 2019, KKR PRA Investors L.P., or KKR, sold 6,666,684 shares of the Company's common stock as part of a secondary offering, or the Secondary Offering, of which the Company repurchased from the underwriter, and subsequently retired, 3,079,765 shares at a price of $97.41 per share, for an aggregate purchase price of approximately $300.0 million. The Company incurred expenses in connection with the Secondary Offering of $0.6 million during the three and nine months ended September 30, 2019. The expenses are included in transaction-related costs in the accompanying consolidated condensed statement of operations.

As of September 30, 2019, the Company has remaining authorization to repurchase up to $200.0 million of its common stock under the Repurchase Program.

The joint venture transaction was effectuated through the creation of a new legal entity, Takeda PRA Development Center KK, or the TDC joint venture. On May 31, 2019, per the terms of the agreement, the TDC joint venture dissolved and the Company acquired Takeda's interest for $4.1 million.

(9) Stock-Based Compensation

Stock Option and RSA/RSU Activity

The 2018 Stock Incentive Plan, or the 2018 Plan, was approved by stockholders at the annual meeting on May 31, 2018. The 2018 Plan allows for the issuance of stock options, stock appreciation rights, restricted shares and restricted stock units, other stock-based awards, and performance compensation awards as permitted by applicable laws. The 2018 Plan authorized the issuance of 2,000,000 shares of common stock plus all shares that remained available under the prior plan on May 31, 2018.

Employee Stock Purchase Plan

In April 2017, the Board ~~of Directors~~ approved the PRA Health Sciences, Inc. 2017 Employee Stock Purchase Plan, or ESPP, which was approved by the Company’s shareholders on June 1, 2017. The ESPP allows eligible employees to authorize payroll deductions of up to 15% of their base salary or wages to be applied toward the purchase of shares of the Company’s common stock on the last trading day of any offering period. Participating employees will purchase shares of the Company's common stock at a discount of up to 15% on the lesser of the closing price of the Company's common stock on the NASDAQ Global Select Market (i) on the first trading day of the offering period or (ii) the last day of any offering period. Offering periods under the ESPP will generally be in six month increments, ~~commencing on January 1 and July 1 of each calendar year~~ with the administrator of the ESPP having the right to establish different offering periods. The Company recognized stock-based compensation expense of ~~$1.1~~$3.0 million and ~~$0.8~~$2.5 million associated with the ESPP during the ~~three~~nine months ended ~~March 31,~~September 30, 2019 and 2018, respectively. As of ~~March 31,~~September 30, 2019, there have been ~~154,019~~242,329 shares issued and ~~2,845,981~~2,757,671 shares reserved for future issuance under the ESPP.

(10) Income Taxes

The Company’s effective income tax rate was ~~38.9%~~25.1% and ~~31.1%~~40.0% for the ~~three~~nine months ended ~~March 31,~~September 30, 2019 and 2018, respectively. The effective tax rate for the ~~three~~nine months ended ~~March 31,~~September 30, 2018 included the effect of ~~a decrease~~an increase in the fair value of the earn-out liability related to the stock acquisition of Symphony Health, which iswas not included in taxable income, but instead ~~decreases~~increased tax stock basis. The variation between the Company’s effective income tax rate and the U.S. statutory rate of 21% for the ~~three~~nine months ended ~~March 31,~~September 30, 2019 is primarily due to (i) the U.S. inclusion of amounts related to the estimated tax on global intangible low-taxed income, or GILTI, (ii) state income taxes, and ~~(ii)~~(iii) the ~~U.S. inclusion~~effects of ~~amounts related to the estimated base erosion anti abuse~~other jurisdictional and permanent differences, including excess tax ~~or BEAT.~~benefits. Significant judgment is required related to the application of the recent U.S. tax reform, ~~(the “Act”),~~or the Act, particularly with respect to GILTI and the base erosion anti-abuse tax, or BEAT, provisions. If changes occur in the Company’s tax structure, the structure of its ~~customer~~ arrangements, or interpretations, ofor regulations that clarify these or other provisions of the Act, these changes could have a material effect on the Company’s tax provision. In the quarter ended September 30, 2019, the Company updated its analysis of BEAT and its impact on the annual estimated effective tax rate for the 2019 tax year to reflect revisions to contractual arrangements.

GAAP requires a two-step approach when evaluating uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence demonstrates that it is more likely than not that the position will be sustained upon audit, including resolution of any related appeals or litigation processes. The second step is to

quantify the amount of tax benefit to recognize as the amount that is cumulatively more than 50% likely to be realized upon ultimate settlement with the taxing authorities. ~~There were no material changes to~~During the ~~unrecognized tax benefits during the three~~nine months ended ~~March 31, 2019.~~September 30, 2019, the liability for uncertain tax positions increased by $18.7 million. This increase in the liability for uncertain tax positions had no impact on income tax expense for the nine months ended September 30, 2019 as it was previously accrued. If such uncertain positions were recognized, they would impact the effective tax rate.

(11) Commitments and Contingencies

Legal Proceedings

The Company is involved in legal proceedings from time to time in the ordinary course of its business, including employment claims and claims related to other business transactions. Although the outcome of such claims is uncertain, management believes that these legal proceedings will not have a material adverse effect on the financial condition or results of future operations of the Company.

The Company is currently a party to litigation with the City of Sao Paulo, Brazil. The dispute relates to whether the export of services provided by the Company is subject to a local tax on services. The Company has not recorded a liability associated with the claim, which totaled ~~$5.0~~$4.9 million at ~~March 31,~~September 30, 2019, given that it is not deemed probable the Company will incur a loss related to this case. However, a deposit totaling ~~$5.0~~$4.9 million has been made to the Brazilian court in order to annul the potential tax obligation and to avoid the accrual of additional interest and penalties. This balance is recorded in other assets on the consolidated condensed balance sheet. In June 2015, the Judiciary Court of Justice of the State of Sao Paulo ruled in the favor of the Company; however, the judgment was appealed by the City of Sao Paulo. In September 2017, a judge from the Superior Court of Justice of Brazil denied relief to the City of Sao Paulo's appeal and upheld the lower court's ruling in favor of the Company for the years 2005 to 2012, and in the period from January to October 2013. The judge from the Superior Court of Justice of Brazil also ruled that the Company must appeal the lower court's verdict for October 2013 and the subsequent periods as the Judiciary Court of Justice of the State of Sao Paulo only reviewed the facts that pertained to the period before October 2013. The Company expects to recover the full amount of the deposit when the case is settled.

(12) Derivatives

The Company is exposed to certain risks relating to its ongoing business operations. The primary risk that the Company seeks to manage by using derivative instruments is interest rate risk arising from movement in market interest rates. Accordingly, the Company has instituted an interest rate hedging program that uses interest rate swaps designated as cash flow hedges to mitigate interest rate volatility. The Company swaps the difference between fixed and variable interest amounts calculated by reference to an agreed-upon notional principal amount, at specified intervals. The Company’s interest rate contracts are designated as hedging instruments.

The following table presents the notional amounts and fair values (determined using Level 2 inputs) of the Company’s derivatives as of ~~March 31,~~September 30, 2019 and December 31, 2018 (in thousands):

~~While the hedge remains effective, the~~The Company records the change in the fair value of derivatives designated as hedging instruments under ASC 815 to accumulated other comprehensive loss in the Company's consolidated condensed balance sheet, net of deferred taxes, and will later reclassify into earnings, including the associated tax impact, when the hedged item affects earnings or is no longer expected to occur. For other derivative contracts that do not qualify or no longer qualify for hedge accounting, changes in the fair value of the derivatives are recognized in earnings each period.

The table below presents the effect of the Company's derivatives on the consolidated condensed statements of operations and comprehensive income for the three and nine months ended ~~March 31,~~September 30, 2019 and 2018 (in thousands):

Foreign Currency Translation

The change in the Company's foreign currency translation adjustment was due primarily to the movements in the British pound, Euro, Canadian dollar and Russian ruble exchange rates against the U.S. dollar. The U.S. dollar strengthened by ~~1.9%~~3.4% and 4.6% versus the British pound and Euro, respectively, and weakened by ~~2.5%~~3.0% and ~~6.7%~~7.3% versus the ~~British pound~~Canadian dollar and the Russian ruble, respectively, between December 31, 2018 and ~~March 31,~~September 30, 2019. The movement in the Euro and British pound ~~and Russian ruble~~ contributed to a ~~$5.0~~$15.7 million and ~~$1.5~~$7.4 million ~~decrease~~increase in ~~accumulated~~ other comprehensive loss, respectively, which was offset by ~~a $6.1 million increase~~decreases in ~~accumulated~~ other comprehensive loss of $1.6 million and $1.1 million due to ~~movements~~movement in the ~~Euro~~Russian ruble and Canadian dollar, respectively, during the ~~three~~nine months ended ~~March 31,~~September 30, 2019.

Derivative Instruments

See ~~Note~~"Note 12 - Derivatives" for further information on changes to accumulated other comprehensive ~~income~~loss related to the derivative instruments.

(14) Net Income Per Share

Basic net income per share is calculated by dividing net income by the weighted average number of common shares outstanding for the applicable period. Diluted net income per share is calculated after adjusting the denominator of the basic net income per share calculation for the effect of all potentially dilutive common shares, which, in the Company’s case, includes shares issuable under the stock option and incentive award plans.

The following table reconciles the basic to diluted weighted average shares outstanding (in thousands):


	Three Months Ended March 31,		Three Months Ended September 30,		Nine Months Ended September 30,
	2019	2018	2019	2018	2019	2018
Basic weighted average common shares outstanding	65,192	63,530	64,771	64,261	65,096	63,891
Effect of dilutive stock options and other awards under share-based compensation programs	1,655	2,631	1,442	2,245	1,511	2,367
Diluted weighted average common shares outstanding	66,847	66,161	66,213	66,506	66,607	66,258

Anti-dilutive shares	1,523	1,936	2,150	987	1,914	1,670

The dilutive and anti-dilutive shares disclosed above were calculated using the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of RSAs/RSUs, reduced by the repurchase of shares with the proceeds from the assumed exercises, and unrecognized compensation expense for outstanding awards.

(15) Segments

The Company is managed through ~~two~~2 reportable segments: (i) the Clinical Research segment and (ii) the Data Solutions segment. In accordance with the provisions of ASC 280, "Segment Reporting", the Company's chief operating decision-maker has been identified as the Chief Executive Officer, who reviews operating results to make decisions about allocating resources and assessing performance for the entire company.


•	Clinical Research Segment: The Clinical Research segment, which primarily serves biopharmaceutical clients, provides outsourced clinical research and clinical trial related services.


•	Data Solutions Segment: The Data Solutions segment provides data and analytics, technology solutions and real-world insights and services primarily to the Company’s life science customers.

The Company's chief operating decision-maker uses segment profit as the primary measure of each segment's operating results in order to allocate resources and in assessing the Company's performance. Asset information by segment is not presented, as this measure is not used by the chief operating decision-maker to assess the Company's performance.

(16) Subsequent Events

~~In April~~On October 28, 2019, the Company ~~made~~refinanced its 2016 Credit Facilities. The Company entered into a new credit agreement with a syndicate of banks for an aggregate principal amount of $1,000.0 million of first lien term debt due in 2024, or the ~~$83.2~~2019 First Lien Term Loan, and a five-year $750.0 million ~~payment associated~~revolving line of credit, collectively known as the 2019 Credit Facilities. The proceeds from the 2019 Credit Facilities were primarily used to repay the 2016 First Lien Term Loan principal balance of $1,191.5 million. The 2019 Credit Facilities also contain customary representations, warranties, affirmative covenants, and events of default. The variable interest rate is a rate equal to LIBOR or ABR, at the election of the Company, plus a margin based on the ratio of total indebtedness to EBITDA. The margin ranges from 1.0% to 2.0%, in the case of LIBOR loans, and 0.0% to 1.0%, in the case of ABR loans. The Company has the option of 1, 2, 3 or 6 month base interest rates. The 2019 First Lien Term Loan requires the Company to repay 2.5% of the original aggregate principal amount per annum in equal quarterly installments beginning on March 31, 2020 through September 30, 2024, with the year-end 2018 earnout to the sellers of Symphony Health Solutions Corporation, which was acquired by the Company in 2017. This payment was recorded in accrued expenses and other current liabilities in the Company's consolidated condensedremaining balance ~~sheets as of March 31, 2019 and December 31, 2018.~~due at maturity.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our consolidated condensed financial statements and the notes thereto included elsewhere in this Quarterly Report on Form 10-Q, with our audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018, ~~(the "Annual Report")~~or the Annual Report, and with the information under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report.

We use the terms “we,” “us,” “our,” or the "Company” in this report to refer to PRA Health Sciences, Inc. and its subsidiaries.

Overview

We are one of the world’s leading global contract research organizations, or CROs, by revenue, providing outsourced clinical development services to the biotechnology and pharmaceutical industries. We believe we are one of a select group of CROs with the expertise and capability to conduct clinical trials across major therapeutic areas on a global basis. Our therapeutic expertise includes areas that are among the largest in pharmaceutical development, and we focus in particular on oncology, immunology, central nervous system inflammation, respiratory, cardiometabolic and infectious diseases. We believe that we further differentiate ourselves from our competitors through our investments in medical informatics and clinical technologies designed to enhance efficiencies, improve study predictability and provide better transparency for our clients throughout their clinical development processes. Our Data Solutions segment allows us to better serve our clients across their entire product lifecycle by (i) improving clinical trial design, recruitment, and execution; (ii) creating real-world data solutions based on the use of medicines by actual patients in normal situations; and (iii) increasing the efficiency of healthcare companies' commercial organizations through enhanced analytics and outsourcing services.

How We Assess the Performance of Our Business

The Company is managed through two reportable segments: (i) the Clinical Research segment; and (ii) the Data Solutions segment. Our chief operating decision-maker uses segment profit as the primary measure of each segment's operating results in order to allocate resources and in assessing the Company's performance. In addition to our financial measures in conformity with U.S. generally accepted accounting principles, or GAAP, including revenue, costs and expenses and other measures discussed below, we review various financial and operational metrics. For our Clinical Research segment, we review new business awards, cancellations, and backlog.

Our gross new business awards for our Clinical Research segment for the ~~three~~nine months ended ~~March 31,~~September 30, 2019 and 2018 were ~~$747.6~~$2,300.3 million and ~~$744.1~~$2,286.7 million, respectively. New business awards arise when a client selects us to execute its trial and is documented by written or electronic correspondence, or for our Strategic Solutions offering when the amount of revenue expected to be recognized is measurable. The number of new business awards can vary significantly from year to year, and awards can have terms ranging from several months to several years. For our Strategic Solutions offering, the value of a new business award is the anticipated revenue to be recognized in the corresponding quarter of the next fiscal year. For the remainder of our Clinical Research segment, the value of a new award is the anticipated revenue over the life of the contract, which does not include reimbursable expenses.

In the normal course of business, we experience contract cancellations, which are reflected as cancellations when the client provides us with written or electronic correspondence that the work should cease. During the ~~three~~nine months ended ~~March 31,~~September 30, 2019 and 2018, we had ~~$83.0~~$295.6 million and ~~$93.9~~$309.3 million, respectively, of cancellations for which we received correspondence from the client for our Clinical Research segment. The number of cancellations can vary significantly from year to year. The value of the cancellation is the remaining amount of unrecognized service revenue, less the estimated effort to transition the work back to the client.

Our backlog consists of anticipated revenue from new business awards that either have not started or are in process but have not been completed for our Clinical Research segment. Backlog varies from period to period depending upon new business awards and contract modifications, cancellations, and the amount of revenue recognized under existing contracts. Our backlog at ~~March 31,~~September 30, 2019 and 2018 was ~~$4.4~~$4.6 billion and ~~$3.8~~$4.1 billion, respectively.

Sources of Revenue

Total revenues are comprised of revenues from the provision of our services and revenues from reimbursed expenses and reimbursable investigator grants that are incurred while providing our services. We do not have any material product revenues.

Costs and Expenses

Our costs and expenses are comprised primarily of our direct costs, selling, general and administrative costs, depreciation and amortization expense and income taxes.

Direct Costs (Exclusive of Depreciation and Amortization)

For our Clinical Research segment, direct costs consist primarily of labor‑related charges. They include elements such as salaries, benefits and incentive compensation for our employees. In addition, we utilize staffing agencies to procure primarily part time individuals to perform work on our contracts. Labor-related charges as a percentage of the Clinical Research segment's total direct costs were ~~96.5%~~96.2% and ~~96.2%~~95.9% for the ~~three~~nine months ended ~~March 31,~~September 30, 2019 and 2018, respectively. The cost of labor procured through staffing agencies is included in these percentages and represents ~~3.0%~~3.1% and 4.5% of the Clinical Research segment's total direct costs for the ~~three~~nine months ended ~~March 31,~~September 30, 2019 and 2018, respectively. Our remaining direct costs are items such as travel, meals, postage and freight, patient costs, medical waste and supplies. The total of all these items as a percentage of the Clinical Research segment's total direct costs were ~~3.5%~~3.8% and ~~3.8%~~4.1% for the ~~three~~nine months ended ~~March 31, 2019 and 2018, respectively.~~

For our Data Solutions segment, direct costs consist primarily of data costs. Data costs as a percentage of the Data Solutions segment's total direct costs were 72.9% and 73.6% for the three months ended March 31, 2019 and 2018, respectively. Labor-related charges, such as salaries, benefits and incentive compensation for our employees, were 19.9% and 19.8% of the Data Solutions segment's total direct costs for the three months ended March 31, 2019 and 2018, respectively. Our remaining direct costs are items such as travel, meals, and supplies and were 7.2% and 6.6% of the Data Solutions segment's total direct costs for the three months ended March 31,September 30, 2019 and 2018, respectively.

Historically, direct costs have increased with an increase in revenues. The future relationship between direct costs and revenues may vary from historical relationships. Several factors will cause direct costs to decrease as a percentage of revenues. Deployment of our billable staff in an optimally efficient manner has the most impact on our ratio of direct cost to revenue. The most effective deployment of our staff is when they are fully engaged in billable work and are accomplishing contract related activities at a rate that meets or exceeds budgeted targets. We also seek to optimize our efficiency by performing work using the employee with the lowest cost. Generally, the following factors may cause direct costs to increase as a percentage of revenues: our staff are not fully deployed, as is the case when there are unforeseen cancellations or delays, or when our staff are accomplishing tasks at levels of effort that exceed budget, such as rework, as well as pricing pressure from increased competition.

For our Data Solutions segment, direct costs consist primarily of data costs. Data costs as a percentage of the Data Solutions segment's total direct costs were 73.3% and 73.0% for the nine months ended September 30, 2019 and 2018, respectively. Labor-related charges, such as salaries, benefits and incentive compensation for our employees, were 20.0% and 20.2% of the Data Solutions segment's total direct costs for the nine months ended September 30, 2019 and 2018, respectively. Our remaining direct costs are items such as travel, meals, and supplies and were 6.7% and 6.8% of the Data Solutions segment's total direct costs for the nine months ended September 30, 2019 and 2018, respectively.

Reimbursable Expenses

As is customary in our industry, we also routinely enter into separate agreements on behalf of our clients with independent physician investigators in connection with clinical trials. We also receive funds from our clients for investigator fees. We are not obligated either to perform the service or to pay the investigator in the event of default by the client. In addition, we do not pay the independent physician investigator until funds are received from the client. We include these investigator fees, as well as our out-of-pocket costs that are reimbursable by our customers, as reimbursable expenses in our consolidated condensed statements of operations.

Reimbursable expenses are not included in our backlog because they are pass-through costs to our clients.

We believe that the fluctuations in reimbursable expenses are not meaningful to the final economic performance as measured on a net basis given that such costs are passed through to the client. The reimbursable expenses are included in our measure of progress for our long-term contracts.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist of administration payroll and benefits, marketing expenditures, and overhead costs such as information technology and facilities costs. These expenses also include central overhead costs that are not directly attributable to our operating business and include certain costs related to insurance, professional fees and property.

Transaction-related Costs

Transaction-related costs ~~for three months ended March 31, 2018~~ include fees associated with our secondary offerings, stock-based compensation expense related to the transfer restrictions on vested options, the amendment to our accounts receivable financing agreement, costs associated with acquisition related earn-out liabilities, and expenses associated with our acquisitions.

Loss on Modification or Extinguishment of Debt

Loss on modification or extinguishment of debt consists of costs incurred in connection with incremental borrowings under our credit facilities and the ~~change in the fair value~~write-off of ~~acquisition-related contingent consideration.~~previously unamortized debt financing costs that were expensed as a result of voluntary debt repayments.

Depreciation and Amortization Expense

Depreciation expense represents the depreciation charged on our fixed assets. The charge is recorded on a straight-line method, based on estimated useful lives of three to seven years for computer hardware and software and five to seven years for furniture and equipment. Leasehold improvements are depreciated over the lesser of the life of the lease term or the useful life of the improvements.

Amortization expense consists of amortization recorded on acquisition-related intangible assets. Customer relationships, backlog and finite-lived trade names are amortized on an accelerated basis, which coincides with the period of economic benefit we expect to receive. All other finite-lived intangibles are amortized on a straight-line basis. In accordance with GAAP, we do not amortize goodwill and indefinite-lived intangible assets.

Income Taxes

Because we conduct operations on a global basis, our effective tax rate has depended and will continue to depend upon the geographic distribution of our pre‑tax earnings among several different taxing jurisdictions. Our effective tax rate can also vary based on changes in the tax rates of the different jurisdictions. Our effective tax rate is also impacted by tax credits and the establishment or release of deferred tax asset valuation allowances and tax reserves, as well as significant non‑deductible items such as portions of transaction‑related costs.

In addition, our effective income tax rate is influenced by U.S. tax law which has been substantially modified by the U.S. Tax Cuts and Jobs Act of 2017, or the Act. The following provisions of the Act could have an adverse effect on our tax rate:

global intangible low-taxed income, or GILTI;

limitations on the U.S. deductions for net business interest;

base erosion anti-abuse provisions, or BEAT; and

performance-based compensation subject to $1 million limit.

Significant judgment is required related to the application of the Act, particularly with respect to GILTI and BEAT provisions. If changes occur in the Company’s tax structure, the structure of its customer arrangements, or interpretations of regulations that clarify these or other provisions of the Act, these changes could have a material effect on the Company’s tax provision.

Foreign subsidiaries are taxed separately in their respective jurisdictions. We have foreign net operating loss carryforwards in some jurisdictions. The carryforward periods for these losses vary from four years to an indefinite carryforward period depending on the jurisdiction. Our ability to offset future taxable income with the net operating loss carryforwards may be limited in certain instances, including changes in ownership.

Exchange Rate Fluctuations

The majority of our foreign operations transact in the Euro, or EUR, or British pound, or GBP. As a result, our revenue and expenses are subject to exchange rate fluctuations with respect to these currencies. We have translated these currencies into U.S. dollars using the following average exchange rates:

Revenue increased by ~~$20.2~~$63.1 million, or ~~2.9%~~8.8%, from ~~$701.8~~$717.6 million during the three months ended ~~March 31,~~September 30, 2018 to ~~$722.0~~$780.7 million during the three months ended ~~March 31,~~September 30, 2019. Revenue for the three months ended ~~March 31,~~September 30, 2019 benefited from an increase in billable hours and volume-related increases in clinical activities as well as an increase in the effective rate of hours billed on our studies, offset by an unfavorable impact of ~~$8.0~~$6.3 million from foreign currency exchange rate fluctuations. The growth in revenue and the increase in billable hours were due largely to the increase in our backlog as we entered the year, the type of services we are providing on our active studies, which was driven by the life cycles of projects that were active during the period, the growth in new business awards as a result of higher demand for our services across the industries we serve, more effective sales efforts, and the growth in the overall CRO market. The increase in our effective rate of the hours billed on our studies is attributable to the contract pricing terms on our current mix of active studies and the mix of clients and services that we provide to those clients.

Direct costs, ~~decreased~~exclusive of depreciation and amortization, increased by ~~$3.5~~$17.9 million, or ~~0.9%~~4.8%, from ~~$381.4~~$371.4 million during the three months ended ~~March 31,~~September 30, 2018 to ~~$377.9~~$389.3 million during the three months ended ~~March 31,~~September 30, 2019. Salaries and related benefits in our Clinical Research segment increased ~~$11.5~~$19.8 million as we continue to hire billable staff to ensure appropriate staffing levels for our current studies and future ~~growth, which~~growth. Data costs in our Data Solutions segment increased

$4.5 million as we continue to expand our sources of data. This was offset by a favorable impact of ~~$14.8~~$6.7 million from foreign currency exchange rate fluctuations. Direct costs as a percentage of revenue were ~~52.3%~~49.9% and ~~54.3%~~51.8% during the three months ended ~~March 31,~~September 30, 2019 and 2018, respectively.

Reimbursable expenses ~~decreased~~increased by ~~$0.4~~$27.2 million from ~~$141.0~~$142.7 million during the three months ended ~~March 31,~~September 30, 2018 to ~~$140.6~~$170.0 million during the three months ended ~~March 31,~~September 30, 2019. We believe that the fluctuations in reimbursable expenses from period to period are not meaningful to our underlying performance over the full terms of the relevant contracts.

Selling, general and administrative expenses increased by ~~$5.4~~$3.0 million, or ~~5.9%~~3.2%, from ~~$91.7~~$92.6 million during the three months ended ~~March 31,~~September 30, 2018 to ~~$97.1~~$95.5 million during the three months ended ~~March 31,~~September 30, 2019. The increase in selling, general and administrative expenses is primarily ~~due~~related to an increase in salaries and related benefits, including ~~a $2.1 million increase in~~ stock-based compensation expense, as we continue to hire staff and add additional office space to support our growing ~~business, and increased facility costs related to additional office space needed for our growth.~~business. Selling, general and administrative expenses as a percentage of revenue were ~~13.4%~~12.2% and ~~13.1%~~12.9% during the three months ended ~~March 31,~~September 30, 2019 and 2018, respectively. The ~~increase~~decrease in selling, general and administrative expenses as a percentage of revenue is primarily related ~~an increase in stock-based compensation during the current year.~~to our continued efforts to effectively leverage our selling and administrative functions.

Transaction-related costs for the three months ended September 30, 2019, totaling $0.6 million, consisted of costs incurred in connection with the September 2019 secondary offering of common stock. For the three months ended ~~March 31,~~September 30, 2018, we ~~recorded an $11.6~~incurred $43.8 million ~~reduction~~of transaction-related costs. These costs consisted of $42.6 million for changes in the estimated fair value of contingent consideration related to ~~transaction-related costs~~our acquisitions, $0.8 million of stock-based compensation expense related to the ~~fair value~~release of the ~~earn-out liability associated~~remaining portion of the transfer restrictions on vested options, and $0.5 million of expenses incurred in connection with ~~the Symphony Health acquisition.~~our August 2018 secondary offering of common stock.

Depreciation and amortization expense ~~increased by $0.3~~was $29.3 million ~~or 1.0%, from $27.3~~and $28.3 million during the three months ended ~~March 31,~~September 30, 2019 and 2018, ~~to $27.6 million during the three months ended March 31, 2019.~~respectively. Depreciation and amortization expense as a percentage of revenue was ~~3.8%~~3.7% during the three months ended ~~March 31,~~September 30, 2019 and 3.9% during the three months ended ~~March 31,~~September 30, 2018. The decrease in depreciation and amortization expense as a percentage of revenue is primarily due the continued amortization of our acquired intangibles which are primarily amortized on an accelerated basis.

Interest expense, net, decreased by ~~$2.5~~$1.4 million, or ~~16.6%~~10.0%, from ~~$14.8~~$14.4 million during the three months ended ~~March 31,~~September 30, 2018 to ~~$12.4~~$13.0 million during the three months ended ~~March 31,~~September 30, 2019. The change is primarily due to a decrease in the weighted average interest rate on our outstanding debt as well as a decrease in the average outstanding debt balance as compared to the three months ended September 30, 2018.

The loss on modification of debt was $1.9 million for the three months ended September 30, 2019, which consisted of costs incurred associated with the incremental borrowing under the senior secured credit facilities. The loss on extinguishment of debt incurred during the three months ended September 30, 2018, totaling $0.5 million, consisted of previously capitalized unamortized debt financing costs that were expensed as a result of voluntary ~~principal prepayments~~debt repayments made during ~~2018.~~the quarter.

Foreign currency gains (losses), net, changed by ~~$6.2~~$7.2 million from foreign currency losses of ~~$0.1~~$1.8 million during the three months ended ~~March 31,~~September 30, 2018 to foreign currency gains of ~~$6.1~~$5.4 million during the three months ended ~~March 31,~~September 30, 2019. Foreign ~~exchange~~currency gains and losses are due to fluctuations in the U.S. dollar, gains or losses that arise in connection with the revaluation of short-term inter-company balances between our domestic and international subsidiaries, and gains or losses from foreign currency transactions, such as those resulting from the settlement of third-party accounts receivables and payables denominated in a currency other than the local currency of the entity making the payment. During the three months ended ~~March 31,~~September 30, 2019, foreign currency gains were primarily due to movement of the U.S. dollar ~~strengthening against~~versus the British pound, the Euro, and Brazilian real.

Provision for income taxes decreased by $16.9 million from $20.2 million during the three months ended September 30, 2018 to $3.4 million during the three months ended September 30, 2019. Our effective tax rate was 91.8% and 3.9% during the three months ended September 30, 2018 and 2019, respectively. In the quarter ended September 30, 2019, we updated our analysis of the base erosion anti-abuse tax, or BEAT, and its impact on the annual estimated effective tax rate for the 2019 tax year to reflect revisions to contractual arrangements, which reduced the effective tax rate for the quarter. For the three months ended September 30, 2019, the annual estimated effective tax rate varied from the U.S. statutory rate of 21% primarily due to (i) the U.S. inclusion of amounts related to the estimated tax on global intangible low-taxed income, or GILTI, (ii) state income taxes, and (iii) the effects of other jurisdictional and permanent differences, including excess tax benefits. The effective tax rate for the three months ended September 30, 2018 was significantly impacted by the transaction costs associated with an increase in fair value of the earn-out liability related to the stock acquisition of Symphony Health, which is not

deductible for tax but instead increases tax stock basis. These quarter events contributed to the comparative reduction in the effective tax rate in the three months ended September 30, 2019 by 87.9%.

Revenue for the nine months ended September 30, 2019 benefited from an increase in billable hours and volume-related increases in clinical activities as well as an increase in the effective rate of hours billed on our studies, offset by an unfavorable impact of $27.0 million from foreign currency exchange rate fluctuations. The growth in revenue and the increase in billable hours were due largely to the increase in our backlog as we entered the year, the type of services we are providing on our active studies, which was driven by the life cycles of projects that were active during the period, the growth in new business awards as a result of higher demand for our services across the industries we serve, more effective sales efforts, and the growth in the overall CRO market.

Salaries and related benefits in our Clinical Research segment increased $44.9 million as we continue to hire billable staff to ensure appropriate staffing levels for our current studies and future growth. Data costs in our Data Solutions segment increased $6.3 million as we continue to expand our sources of data. These were offset by a favorable impact of $32.4 million from foreign currency exchange rate fluctuations. Direct costs as a percentage of revenue were 50.9% and 53.0% during the nine months ended September 30, 2019 and 2018, respectively.

Reimbursable expenses increased by $40.8 million from $430.9 million during the nine months ended September 30, 2018 to $471.7 million during the nine months ended September 30, 2019.

Selling, general and administrative expenses increased by $16.0 million, or 5.8%, from $275.4 million during the nine months ended September 30, 2018 to $291.4 million during the nine months ended September 30, 2019. The increase in selling, general and administrative expenses is primarily due to an increase in salaries and related benefits, including stock-based

compensation expense as we continue to hire staff and add additional office space to support our growing business. Selling, general and administrative expenses as a percentage of revenue were 12.9% during the nine months ended September 30, 2019 and 2018.

Transaction-related costs for the nine months ended September 30, 2019, totaling $0.6 million, consisted of costs incurred in connection with the September 2019 secondary offering of common stock. For the nine months ended September 30, 2018, we recorded $32.7 million of transaction-related costs. These costs consisted of $30.9 million for changes in the estimated fair value of contingent consideration related to our acquisitions, $0.8 million of stock-based compensation expense related to the release of a portion of the transfer restrictions on vested options, $0.5 million of third-party fees associated with the amendment to our accounts receivable financing agreement and $0.5 million of expenses incurred in connection with our August 2018 secondary offering of common stock.

Depreciation and amortization expense increased by $1.3 million, or 1.5%, from $84.2 million during the nine months ended September 30, 2018 to $85.5 million during the nine months ended September 30, 2019. Depreciation and amortization expense as a percentage of revenue was 3.8% during the nine months ended September 30, 2019 and 3.9% during the nine months ended September 30, 2018.

Interest expense, net, decreased by $6.0 million, or 13.7%, from $43.9 million during the nine months ended September 30, 2018 to $37.8 million during the nine months ended September 30, 2019. The change is primarily due to the voluntary principal prepayments made during 2018 and 2019 which was partially offset by interest expense incurred on the September 2019 incremental borrowing.

The loss on modification of debt was $1.9 million for the nine months ended September 30, 2019, and consisted of costs incurred associated with the incremental borrowing under the senior secured credit facilities. The loss on extinguishment of debt incurred during the nine months ended September 30, 2018, totaling $0.5 million, consisted of previously capitalized unamortized debt financing costs that were expensed as a result of voluntary debt repayments made during the period.

Foreign currency gains and losses are due to fluctuations in the U.S. dollar, gains or losses that arise in connection with the revaluation of short-term inter-company balances between our domestic and international subsidiaries, and gains or losses from foreign currency transactions, such as those resulting from the settlement of third-party accounts receivables and payables denominated in a currency other than the local currency of the entity making the payment. During the nine months ended September 30, 2019, foreign currency gains were primarily due to movement of the U.S. dollar versus the British pound and the Euro.

Although our business is not generally seasonal, we typically experience a slight decrease in our revenue growth rate during the fourth quarter due to holiday vacations and a similar decrease in new business awards in the first quarter due to our clients’ budgetary cycles and vacations during the year-end holiday period.

Liquidity and Capital Resources

We assess our liquidity in terms of our ability to generate cash to fund our operating, investing and financing activities. Our principal source of liquidity is operating cash flows. As of ~~March 31,~~September 30, 2019, we had approximately ~~$177.1~~$181.8 million of cash and cash equivalents of which ~~$50.8~~$56.0 million was held by our foreign subsidiaries. Our expected primary cash needs on both a short and long-term basis are for capital expenditures, expansion of services, geographic expansion, debt repayments, acquisitions and other strategic transactions, and other general corporate purposes. We have historically funded our operations and growth, including acquisitions, with cash flow from operations, borrowings, and issuances of equity securities. We expect to continue expanding our operations through internal growth and strategic acquisitions and investments. We expect these activities will be funded from existing cash, cash flow from operations and, if necessary or appropriate, borrowings under our existing or future credit facilities. Our sources of liquidity could be affected by our dependence on a small number of industries and clients, compliance with regulations, international risks, and personal injury, environmental or other material litigation claims.

Cash Collections

Cash collections from accounts receivable were ~~$702.5~~$2,195.2 million during the ~~three~~nine months ended ~~March 31,~~September 30, 2019, including ~~$81.4~~$261.5 million of funds received from customers to pay independent physician investigators, or investigators, as compared to ~~$680.9~~$2,133.0 million during the ~~three~~nine months ended ~~March 31,~~September 30, 2018, including ~~$67.1~~$258.3 million of funds received from customers to pay investigators. The increase in cash collections during the ~~three~~nine months ended ~~March 31,~~September 30, 2019 is related to our increase in revenue, driven by an increase in new business awards and an increase in our backlog.

Discussion of Cash Flows

Cash Flow from Operating Activities

During the ~~three~~nine months ended ~~March 31,~~September 30, 2019, net cash provided by operations was ~~$41.0~~$66.0 million compared to ~~$34.6~~$198.6 million provided by operations for the same period of 2018. Cash ~~provided by~~from operating activities ~~increased~~decreased over the prior year primarily due to ~~a decrease~~an increase in cash outflows associated with acquisition related earn-out payments ~~offset by~~as well as an increase in cash outflows from working capital. The changes in working capital were driven by changes in our accounts receivable, unbilled services and advanced billings accounts, as a result of an increase in our days sales outstanding as compared to the prior year.

Cash Flow from Investing Activities

Net cash used in investing activities was ~~$19.1~~$59.7 million during the ~~three~~nine months ended ~~March 31,~~September 30, 2019 compared to ~~$14.2~~$39.7 million for the same period of 2018. Cash outflows from capital expenditures increased from ~~$13.8~~$40.1 million during the ~~three~~nine months ended ~~March 31,~~September 30, 2018 to ~~$19.9~~$61.2 million during the same period in 2019. The increase in capital expenditures is primarily related to leasehold improvements and furniture and fixtures associated with new office space added to support our growing business.

Cash Flow from Financing Activities

Net cash provided by financing activities was ~~$10.4~~$31.0 million during the ~~three~~nine months ended ~~March 31,~~September 30, 2019 compared to net cash used in financing activities of ~~$84.6~~$221.6 million for the same period of 2018. During the nine months ended September 30, 2019 our long-term debt balances increased by $305.0 million compared to a $155.9 million decrease for the same period of 2018. Additionally, cash flows for the nine months ended September 30, 2019 include an additional $10.9 million of cash inflows from our employee stock purchase plan as compared to the same period in the prior year. The remaining change in cash flows from financing activities is primarily attributable to cash outflows for the repurchase and retirement of common stock in the current year and the portion of acquisition related earn-out payments being classified as a financing activity in the prior year. Additionally, cash flows for the three months ended March 31, 2019 include cash inflows from our employee stock purchase plan. Our voluntary debt prepayments during 2018 fully satisfied all required quarterly principal payments through maturity.

Indebtedness

As of ~~March 31,~~September 30, 2019, we had ~~$1,086.5~~$1,391.5 million of total indebtedness. Additionally, our 2016 Revolver ~~provides~~provided $225.0 million of potential borrowings. At ~~March 31,~~September 30, 2019, we had no outstanding borrowings under our 2016 Revolver and had ~~$5.5~~$5.2 million in letters of credit outstanding, which ~~are~~were secured by the 2016 Revolver. We do not expect to pay dividends in the foreseeable future. Our long-term debt arrangements contain usual and customary restrictive covenants, and, as of ~~March 31,~~September 30, 2019, we were in compliance with these covenants.

On October 25, 2019, we refinanced our 2016 Credit Facilities by entering into the 2019 Credit Facilities. We entered into the 2019 First Lien Term Loan, with a syndicate of banks for an aggregate principal amount of $1,000.0 million of first lien term debt due in 2024, and a five-year $750.0 million revolving line of credit. The proceeds from the 2019 Credit Facilities were used to repay the 2016 First Lien Term Loan principal balance of $1,191.5 million and approximately $4.5 million in related fees and expenses.

Website and Social Media Disclosure

We use our website (www.prahs.com) as a channel of distribution of company information. The information we post through this channel may be deemed material.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Item 4. Controls and Procedures

As of ~~March 31,~~September 30, 2019, we carried out an evaluation under the supervision and with the participation of our management, including the principal executive officer and principal financial officer, of the effectiveness of the design and

operation of our disclosure controls and procedures. Regulations under the ~~Securities~~ Exchange Act ~~of 1934, as amended (the "Exchange Act")~~ require public companies, including us, to maintain “disclosure controls and procedures,” which are defined in Rule 13a-15(e) and Rule 15d-15(e) of the Exchange

Act to mean a company’s controls and other procedures that are designed to ensure that information required to be disclosed in reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including our principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required or necessary disclosures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective to accomplish their objective at a reasonable assurance level.

There were no changes in our internal control over financial reporting (as that term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended ~~March 31,~~September 30, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
