1.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

EPAM Systems, Inc. (the “Company” or “EPAM”) is a leading global provider of digital platform engineering and software development services to clients located around the world, primarily in North America, Europe, Asia and Australia. The Company has expertise in various industries, including software and hi-tech, financial services, media and entertainment, travel and hospitality, retail and distribution and life sciences and healthcare. The Company is incorporated in Delaware and headquartered in Newtown, PA.

Basis of Presentation — The accompanying unaudited condensed consolidated financial statements of EPAM have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and Article 10 of Regulation S-X under the Securities Exchange Act of 1934, as amended. The condensed consolidated financial statements include the financial statements of EPAM Systems, Inc. and its subsidiaries with all intercompany balances and transactions eliminated.

These unaudited condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2016 included in its Annual Report on Form 10-K. The preparation of these condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates, and such differences may be material to the condensed consolidated financial statements. Operating results for the interim periods are not necessarily indicative of results that may be expected to occur for the entire year. In our opinion, all adjustments considered necessary for a fair presentation of the accompanying unaudited condensed consolidated financial statements have been included, and all adjustments are of a normal and recurring nature.

Table of Contents

Change in Presentation of Certain Financial Information — During the first quarter of 2017, the Company changed the presentation of geographic area information about its consolidated revenues. Historically, information about geographic location of revenues excluded reimbursable expenses and other revenues, which primarily consist of travel and entertainment costs that are chargeable to clients. Effective January 1, 2017, the Company began reporting reimbursable expenses and other revenues based on location of clients to which these costs are chargeable and allocating them to respective geographic locations. These changes did not result in any adjustments to the Company’s previously issued financial statements and were applied retrospectively beginning on January 1, 2015. Comparative information for the three and nine months ended September 30, 2016 follows:

Revenue Recognition — The Company recognizes revenue when the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred; (3) the sales price is fixed or determinable; and (4) collectability is reasonably assured. Determining whether and when some of these criteria have been satisfied often involves assumptions and judgments that can have a significant impact on the timing and amount of revenue reported.

The Company derives its revenues from a variety of service offerings, which represent specific competencies of its IT professionals. Contracts for these services have different terms and conditions based on the scope, deliverables, and complexity of the engagement, which require management to make judgments and estimates in determining the appropriate revenue recognition. Fees for these contracts may be in the form of time-and-materials or fixed-price arrangements. If there is an uncertainty about the project completion or receipt of payment for the services, revenue is deferred until the uncertainty is sufficiently resolved. At the time revenue is recognized, the Company provides for any contractual deductions and reduces the revenue accordingly. The Company reports gross reimbursable “out-of-pocket” expenses incurred as both revenues and cost of revenues in the condensed consolidated statements of income and comprehensive income.

The Company defers amounts billed to its clients for revenues not yet earned. Such amounts are anticipated to be recorded as revenues when services are performed in subsequent periods. Unbilled revenue is recorded when services have been provided but billed subsequent to the period end in accordance with the contract terms.

Fair Value of Financial Instruments — The Company makes assumptions about fair values of its financial assets and liabilities in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurement”, and utilizes the following fair value hierarchy in determining inputs used for valuation:

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

Level 2 — Inputs other than quoted prices within Level 1 that are observable either directly or indirectly, including quoted prices in markets that are not active, quoted prices in active markets for similar assets or liabilities, and observable inputs other than quoted prices such as interest rates or yield curves.

Level 3 — Unobservable inputs reflecting our view about the assumptions that market participants would use in pricing the asset or liability.

Table of Contents

Where the fair values of financial assets and liabilities recorded in the condensed consolidated balance sheets cannot be derived from an active market, they are determined using a variety of valuation techniques. These valuation techniques include a net present value technique, comparison to similar instruments with market observable inputs, option pricing models and other relevant valuation models. To the extent possible, observable market data is used as inputs into these models but when it is not feasible, a degree of judgment is required to establish fair values.

Changes in fair value could cause a material impact to, and volatility in the Company’s operating results. See Note 3 for disclosures related to fair value.

Business Combinations — The Company accounts for its business combinations using the acquisition accounting method, which requires it to determine the fair value of net assets acquired and the related goodwill and other intangible assets in accordance with the FASB ASC Topic 805, “Business Combinations.” A portion of the purchase price is usually allocated to goodwill and other intangible assets. The acquired assets typically consist of customer relationships, trade names, non-competition agreements, and assembled workforce. The Company identifies and attributes fair values and estimated lives to the intangible assets acquired and allocates the total cost of an acquisition to the underlying net assets based on their respective estimated fair values. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and involves the use of significant estimates, including projections of future cash inflows and outflows, discount rates, asset lives and market multiples. There are different valuation models for each component, the selection of which requires considerable judgment. These determinations will affect the amount of amortization expense recognized in future periods. The Company bases its fair value estimates on assumptions it believes are reasonable, but recognizes that the assumptions are inherently uncertain.

All acquisition-related costs, other than the costs to issue debt or equity securities, are accounted for as expenses in the period in which they are incurred. Changes in fair value of contingent consideration arrangements that are not measurement period adjustments are recognized in earnings. Payments to settle contingent consideration up to the acquisition-date fair value are reflected in cash flows used in financing activities and amounts paid in excess of acquisition-date fair value are reflected in cash flows from operating activities in the Company’s condensed consolidated statements of cash flows.

Goodwill and Other Intangible Assets — Goodwill and other intangible assets that have indefinite useful lives are accounted for in accordance with FASB ASC 350, “Intangibles - Goodwill and Other.” The Company conducts its evaluation of goodwill impairment at the reporting unit level on an annual basis during its fourth quarter, and more frequently if events or circumstances indicate that the carrying value of a reporting unit exceeds its fair value. A reporting unit is an operating segment or one level below. The Company does not have intangible assets that have indefinite useful lives.

Intangible assets that have finite useful lives are amortized over their estimated useful lives on a straight-line basis. When facts and circumstances indicate potential impairment of amortizable intangible assets, the Company evaluates the recoverability of the asset’s carrying value, using estimates of future cash flows over the remaining asset life. The estimates of future cash flows attributable to intangible assets require significant judgment based on the Company’s historical and anticipated results. Any impairment loss is measured by the excess of carrying value over fair value.

Stock-Based Compensation — The Company recognizes the cost of its stock-based incentive awards based on the fair value of the award at the date of grant, net of estimated forfeitures. The cost is expensed evenly over the service period. The service period is the period over which the employee performs the related services, which is normally the same as the vesting period. Over time, the forfeiture assumption is adjusted to the actual forfeiture rate and such change may affect the timing of the total amount of expense recognized over the vesting period. Equity-based awards that do not require future service are expensed immediately. Equity-based awards that do not meet the criteria for equity classification are recorded as liabilities and adjusted to fair value at the end of each reporting period.

Off-Balance Sheet Financial Instruments — The Company uses FASB ASC Topic 825, “Financial Instruments” to identify and disclose off-balance sheet financial instruments, which include credit instruments, such as commitments to make employee loans and related guarantees, standby letters of credit and certain guarantees issued under customer contracts. The face amount for these items represents the exposure to loss, before considering available collateral or the borrower’s ability to repay. Loss contingencies arising from off-balance sheet financial instruments are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. The Company does not believe such matters exist that will have a material effect on the condensed consolidated financial statements.

There were no accumulated impairment losses in the North America or Europe reportable segments as of September 30, 2017 or December 31, 2016 .


3.	FAIR VALUE MEASUREMENTS

The Company carries certain liabilities at fair value on a recurring basis on its consolidated balance sheets. Changes in the fair values of these financial liabilities are recorded in cost of revenues and selling, general and administrative expenses on the Company’s consolidated statements of income and comprehensive income.

The following tables show the fair values of the Company’s financial liabilities measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016 :



	As of September 30, 2017
	Balance		Level 1		Level 2		Level 3
Cash-settled restricted stock units	$	2,890	$	2,890	—		—
Total liabilities measured at fair value on a recurring basis	$	2,890	$	2,890	$	—	$	—



	As of December 31, 2016
	Balance		Level 1		Level 2		Level 3
Performance-based equity awards	$	3,789	$	3,789	$	—	$	—
Cash-settled restricted stock units	2,111		2,111		—		—
Total liabilities measured at fair value on a recurring basis	$	5,900	$	5,900	$	—	$	—

Performance-based equity awards carried at fair value on a recurring basis represent contractual liabilities related to certain business combination transactions completed in 2014. All of these awards have vested as of September 30, 2017 and the related liabilities have been settled.

The fair value of cash-settled restricted stock units is measured using quoted stock market prices and thus represent Level 1 measurements within the fair value hierarchy.

Estimates of fair value of financial instruments not carried at fair value on a recurring basis on the Company’s consolidated balance sheets are generally subjective in nature, and are determined as of a specific point in time based on the characteristics of the financial instruments and relevant market information. The Company uses the following methods to estimate the fair values of its financial instruments:


•	for financial instruments that have quoted market prices, those quoted prices are used to estimate fair value;


•	for financial instruments for which no quoted market prices are available, fair value is estimated using information obtained from independent third parties, or by discounting the expected cash flows using an estimated current market interest rate for the financial instrument;


•	for financial instruments for which no quoted market prices are available and that have no defined maturity, have a remaining maturity of 360 days or less, or reprice frequently to a market rate, the Company assumes that the fair value of these instruments approximates their reported value, after taking into consideration any applicable credit risk.

Table of Contents

The generally short duration of certain of the Company’s assets and liabilities results in a number of assets and liabilities for which fair value equals or closely approximates the amount recorded on the Company’s consolidated balance sheets. These types of assets and liabilities which are reported on the Company’s condensed consolidated balance sheets include:


•	cash and cash equivalents;


•	restricted cash and time deposits;


•	long-term debt (Note 4 ).

The fair value of employee housing loans is estimated using information on the rates of return that market participants in Belarus would require when investing in unsecured U.S. dollar-denominated government bonds with similar maturities (a “risk-free rate”), after taking into consideration any applicable credit and liquidity risk.

The following tables present the reported amounts and estimated fair values of the financial assets and liabilities for which disclosure of fair value is required, as they would be categorized within the fair value hierarchy, as of the dates indicated:

4.	DEBT

Revolving Line of Credit — On May 24, 2017, the Company entered into a new unsecured credit facility (the “2017 Credit Facility”) with PNC Bank, National Association; PNC Capital Markets LLC; Wells Fargo Bank, National Association; Santander Bank, N.A.; Fifth Third Bank and Citibank N.A. (collectively the “Lenders”) to replace its former revolving credit facility (the “2014 Credit Facility”). The 2017 Credit Facility provides for a borrowing capacity of $300,000 , with potential to increase the credit facility up to $400,000 if certain conditions are met. The 2017 Credit Facility matures on May 24, 2022 .

Borrowings under the 2017 Credit Facility may be denominated in U.S. dollars or up to a maximum of $100,000 equivalent in British pounds sterling, Canadian dollars, euros or Swiss francs (or other currencies as may be approved by the Administrative Agent and the Lenders). Borrowings under the 2017 Credit Facility bear interest at either a base rate or Euro-rate plus a margin based on the Company’s leverage ratio. Base rate is equal to the highest of (a) the Overnight Bank Funding Rate, plus 0.5% , (b) the Prime Rate, and (c) the Daily LIBOR Rate, plus 1.0% .

The 2017 Credit Facility includes customary business and financial covenants that may restrict the Company’s ability to make or pay dividends (other than certain intercompany dividends) if a potential or an actual event of default has occurred or would be triggered. As of September 30, 2017 , the Company was in compliance with all covenants contained in the 2017 Credit Facility.

Table of Contents

As of September 30, 2017 , the outstanding debt of the Company under the 2017 Credit Facility was $25,000 . As of December 31, 2016 , the outstanding debt of the Company under the 2014 Credit Facility was $25,000 . Both borrowings are subject to a LIBOR-based interest rate, which resets regularly at issuance, based on lending terms.

As of September 30, 2017 , the Company had $1,289 of irrevocable standby letters of credit. As of December 31, 2016 , the Company had a $942 irrevocable standby letter of credit.

As of September 30, 2017 , the borrowing capacity of the Company under the 2017 Credit Facility was $273,711 . As of December 31, 2016 , the borrowing capacity of the Company under the 2014 Credit Facility was $74,058 .


5.	INCOME TAXES

In determining its interim provision for income taxes, the Company uses an estimated annual effective tax rate, which is based on expected annual profit before tax, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rates from quarter to quarter. The Company’s worldwide effective tax rate for the three months ended September 30, 2017 and 2016 was 15.7% and 21.3% , respectively and 15.2% and 21.1% during the nine months ended September 30, 2017 and 2016 , respectively. The decrease in the three and nine months ended September 30, 2017 as compared to the same periods last year was primarily due to the recognition of excess tax benefits in the provision for income taxes in 2017 following the adoption of ASU No. 2016-09 on January 1, 2017. Refer to Note 10 , “Recent Accounting Pronouncements,” for further information.

Our Belarus subsidiary is eligible for certain income tax holiday benefits granted by the local government for its export activities conducted within the Belarus Hi-Tech Park. The income tax holiday benefits are effective for 15 years starting from 2006. Other subsidiaries of the Company are primarily taxed at the jurisdictions’ statutory rate, which are lower than U.S. federal statutory rates.

2012 Long-Term Incentive Plan — On January 11, 2012, the Company approved the 2012 Long-Term Incentive Plan (“2012 Plan”) to be used to issue equity awards to company personnel. In June 2015, the 2012 Plan was discontinued; however, outstanding awards remain subject to the terms of the 2012 Plan and any shares that are subject to an award that was previously granted under the 2012 Plan and that expire or terminate for any reason prior to exercise will become available for issuance under the 2015 Plan. All of the stock option awards issued pursuant to the 2012 Plan expire 10 years from the date of grant.

Table of Contents

2006 Stock Option Plan — Effective May 31, 2006, the Board of Directors of the Company adopted the 2006 Stock Option Plan (the “2006 Plan”) to grant stock options to directors, employees, and certain independent contractors.

As of September 30, 2017 , a total of 44,423 shares underlying options exercised through September 30, 2017 , were in transfer with the Company’s transfer agent.

There were no material changes with respect to the assumptions used in the Black-Scholes option valuation model during the nine months ended September 30, 2017 , as compared with the assumptions disclosed in Note 14 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016 .

Restricted Stock and Restricted Stock Units

Under the Company’s 2012 Directors Plan, the Company granted awards of restricted stock until April 2017, and thereafter, grants restricted stock units (“RSUs”), to non-employee directors. Under the Company’s 2015 Plan (and prior to its approval, the 2012 Plan), the Company grants awards of RSUs to Company personnel. In addition, the Company has issued in the past, and may issue in the future its equity securities to compensate employees of acquired businesses for future services. Equity-based awards granted in connection with acquisitions of businesses are generally issued in the form of service-based awards with vesting dependent only on continuing employment and performance-based awards with vesting occurring only if certain specified performance conditions are met. The awards issued in connection with acquisitions of businesses are subject to the terms and conditions contained in the applicable award agreement and acquisition documents with a typical vesting period of three years , with 33.3% of the awards granted vesting in equal installments on the first, second and third anniversaries of the grant.

Table of Contents

As of September 30, 2017 , the Company determined that there is a remote probability of achieving the performance conditions underlying the unvested and outstanding performance-based equity-classified RSUs and therefore is not recognizing any compensation costs for these RSUs. The Company will continue to reassess the probability of achieving the performance criteria throughout the remaining performance period and will recognize compensation expense if the performance conditions become probable of being achieved.

Modifications

During the three months ended March 31, 2017, the Company modified certain awards held by a then named executive officer of the Company in connection with the execution of a separation agreement on February 28, 2017. Fair value of the modified awards immediately before and after modification was $0 and $563 , respectively. As a result of this modification, the Company recorded incremental share-based compensation expense of $78 and $563 for the three and nine months ended September 30, 2017, respectively.


7.	EARNINGS PER SHARE

Basic earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, unvested restricted stock and unvested equity-settled RSUs. The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method.

The following table sets forth the computation of basic and diluted earnings per share of common stock as follows:



	Three Months Ended September 30,				Nine Months Ended September 30,
	2017		2016		2017		2016
Numerator for basic and diluted earnings per share:
Net income	$	42,634	$	26,174	$	103,634	$	74,503
Numerator for basic and diluted earnings per share	$	42,634	$	26,174	$	103,634	$	74,503

Denominator:
Weighted average common shares for basic earnings per share	52,545		51,131		51,807		50,172
Net effect of dilutive stock options, restricted stock units and restricted stock awards	2,684		2,733		2,855		2,987
Weighted average common shares for diluted earnings per share	55,229		53,864		54,662		53,159

Net income per share:
Basic	$	0.81	$	0.51	$	2.00	$	1.48
Diluted	$	0.77	$	0.49	$	1.90	$	1.40

The number of shares underlying equity–based awards that was excluded from the calculation of diluted earnings per share as their effect would be anti–dilutive was 606 and 1,177 during the three and nine months ended September 30, 2017 , respectively. The number of shares underlying equity–based awards that was excluded from the calculation of diluted earnings per share as their effect would be anti–dilutive was 2,357 and 2,324 during the three and nine months ended September 30, 2016 , respectively.


8.	COMMITMENTS AND CONTINGENCIES

Indemnification Obligations — In the normal course of business, the Company is a party to a variety of agreements under which it may be obligated to indemnify the other party for certain matters. These obligations typically arise in contracts where the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations or covenants for certain matters such as title to assets and intellectual property rights associated with certain arrangements. The duration of these indemnifications varies, and in certain cases, is indefinite.

Table of Contents

The Company is unable to reasonably estimate the maximum potential amount of future payments under these or similar agreements due to the unique facts and circumstances of each agreement and the fact that certain indemnifications provide for no limitation to the maximum potential future payments under the indemnification. Management is not aware of any such matters that would have a material effect on the condensed consolidated financial statements of the Company.

Litigation — From time to time, the Company is involved in litigation, claims or other contingencies arising in the ordinary course of business. The Company accrues a liability when a loss is considered probable and the amount can be reasonably estimated. When a material loss contingency is reasonably possible but not probable, the Company does not record a liability, but instead discloses the nature and the amount of the claim, and an estimate of the loss or range of loss, if such an estimate can be made. Legal fees are expensed as incurred. In the opinion of management, the outcome of any existing claims and legal or regulatory proceedings, if decided adversely, is not expected to have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows.


9.	SEGMENT INFORMATION

The Company determines its business segments and reports segment information in accordance with how the Company’s chief operating decision maker (“CODM”) organizes the segments to evaluate performance, allocate resources and make business decisions. Segment results are based on the segment’s revenues and operating profit, where segment operating profit is defined as income from operations before unallocated costs. Generally, operating expenses for each reportable segment have similar characteristics and are subject to similar factors, pressures and challenges. Expenses included in segment operating profit consist principally of direct selling and delivery costs as well as an allocation of certain shared services expenses. Certain expenses are not allocated to specific segments as these expenses are not directly attributable to or controllable at the segment level. Further, stock based compensation expense is not allocated to individual segments in internal management reports used by the CODM. These unallocated amounts are combined with total segment operating profit to arrive at consolidated income from operations as reported below in the reconciliation of segment operating profit to consolidated income before provision for income taxes.

The Company manages its business primarily based on the managerial responsibility for its client base. As managerial responsibility for a particular client relationship generally correlates with the client’s geographic location, there is a high degree of similarity between client locations and the geographic boundaries of the Company’s reportable segments. In some cases, managerial responsibility for a particular client is assigned to a management team in another region and is usually based on the strength of the relationship between client executives and particular members of EPAM’s senior management team. In such cases, the client’s activity would be reported through the management team’s reportable segment.

The Company’s reportable segments are North America, Europe, Russia and Other. The revenues in the Other segment represented less than 1% of total segment revenues in 2015 due to the ending of certain customer relationships and contractual changes with other clients. As no substantial clients remained in the segment, during the first quarter of 2016, the Company shifted managerial responsibility for the remaining clients to the Russia segment. This change did not represent a change in the Company’s segments but rather a movement in responsibility for several clients that represented less than 1% of total segment revenue.

Revenues from external customers and operating profit, before unallocated expenses, for the North America, Europe, and Russia reportable segments for the three and nine months ended September 30, 2017 and 2016 , were as follows:



	Three Months Ended September 30,				Nine Months Ended September 30,
	2017		2016		2017		2016
Segment revenues:
North America	$	206,389	$	161,655	$	578,717	$	466,255
Europe	157,446		126,265		431,472		349,834
Russia	14,455		10,434		41,825		31,056
Total segment revenues	$	378,290	$	298,354	$	1,052,014	$	847,145
Segment operating profit:
North America	$	45,529	$	34,699	$	126,243	$	103,693
Europe	25,984		19,548		66,453		49,793
Russia	1,685		1,208		7,129		5,244
Total segment operating profit	$	73,198	$	55,455	$	199,825	$	158,730

Table of Contents

Intersegment transactions were excluded from the above on the basis that they are neither included in the measure of a segment’s profit and loss results, nor considered by the CODM during the review of segment results.

There were no customers that accounted for more than 10% of total revenues during the three and nine months ended September 30, 2017 . During the three and nine months ended September 30, 2016 , revenues from one customer, UBS AG , were $35,142 and $107,381 , respectively, and accounted for more than 10% of total revenues. Revenues from this customer were included in the Company’s Europe segment in the periods indicated.

Accounts receivable and unbilled revenues are generally dispersed across our clients in proportion to their revenues. As of September 30, 2017 , accounts receivable from one customer, UBS AG , individually exceeded 10% and accounted for 10.5% of our total accounts receivable. As of September 30, 2017 , unbilled revenues from one customer, Expedia , individually exceeded 10% and accounted for 10.9% of our total unbilled revenues.

10.	RECENT ACCOUNTING PRONOUNCEMENTS

Adoption of New Accounting Standards

Unless otherwise discussed below, the adoption of new accounting standards did not have an impact on the Company’s consolidated financial position, results of operations, and cash flows.

Table of Contents

Stock-Based Compensation — Effective January 1, 2017, the Company adopted Accounting Standard Update (“ASU”) No. 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . The provisions of the new guidance affecting the Company require excess tax benefits and tax deficiencies to be recorded in the income statement when the awards vest or are settled; remove the requirement to include hypothetical excess tax benefits in the application of the treasury stock method when computing earnings per share; and provide for a new policy election to either: (1) continue applying forfeiture rate estimates in the determination of compensation cost, or (2) account for forfeitures as a reduction of share-based compensation cost as they occur. The new guidance also requires cash flows related to excess tax benefits to be classified as an operating activity in the statement of cash flows and now requires shares withheld for tax withholding purposes to be classified as a financing activity.

As a result of this adoption:


•	the Company prospectively recognized discrete tax benefits of $2,620 and $8,452 in the provision for income taxes within the condensed consolidated statements of income and comprehensive income for the three and nine months ended September 30, 2017, respectively, related to excess tax benefits upon vesting and exercise of stock–based awards in those periods;


•	the Company recognized a $1,740 increase in retained earnings as of January 1, 2017 for previously unrecognized tax benefits using the modified retrospective method of transition, as required by the standard;


•	the Company elected to adopt the cash flow presentation of the excess tax benefits prospectively where these benefits are classified along with other income tax cash flows as operating cash flows. Accordingly, prior period information has not been restated;


•	the Company elected to continue to estimate the number of stock-based awards expected to forfeit, rather than electing to account for forfeitures as they occur to determine the amount of compensation cost to be recognized in each period; and


•	the Company excluded the excess tax benefits from the assumed proceeds available to repurchase shares in the computation of diluted earnings per share for the three and nine months ended September 30, 2017.

Simplifying the Measurement for Goodwill — Effective January 1, 2017, the Company early adopted the new accounting guidance simplifying the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The new guidance is adopted on a prospective basis. The adoption of this amended guidance did not have an impact on the Company’s financial results.

Pending Accounting Standards

From time to time, new accounting pronouncements are issued by the FASB or other standards-setting bodies that the Company will adopt according to the various timetables the FASB specifies. Unless otherwise discussed below, the Company believes the impact of recently issued standards that are not yet effective will not have a material impact on its consolidated financial position, results of operations and cash flows upon adoption.

Revenue Recognition — In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) . The core principle of Topic 606 is that an entity should recognize revenue to depict the transfer of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Topic 606 as amended, will replace most existing revenue recognition guidance in GAAP and requires expanded disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. The standard allows for two methods of adoption: the full retrospective method, which requires the standard to be applied to each prior period presented, or the modified retrospective method, which requires the cumulative effect of adoption to be recognized as an adjustment to opening retained earnings in the period of adoption as well as incremental disclosure comparing results presented under Topic 606 to results that would have been presented utilizing current accounting. The Company plans to adopt Topic 606 as issued and amended on January 1, 2018 using the modified retrospective method.

Table of Contents

The Company completed its initial assessment of the impact of Topic 606 and has developed a transition plan, which includes making necessary changes to policies, processes, internal controls and system enhancements to generate the information necessary to comply with the new standard. Based on the assessment procedures completed, the Company does not expect a significant change in the timing or pattern of revenue recognition upon adoption. Due to the complexity of certain of the Company’s contracts, actual revenue recognition treatment required under the new standard depends on contract-specific terms and may vary in some instances. For most of the Company’s time-and-materials contracts, EPAM expects to continue to recognize revenues as services are performed consistent with the Company’s current policy. For fixed-price contracts, the Company generally expects to continue to recognize revenues over time based on the measured progress of satisfaction of the performance obligations which is consistent with the Company’s current proportional performance method. The most impactful changes expected upon adoption include a delay in revenue recognition related to (1) cash collections on contracts when collectability is uncertain and (2) discounted services determined to represent material rights granted to certain customers. Upon adoption, EPAM expects to provide incremental disclosure in its consolidated financial statements related to revenue recognition including disaggregated information related to the Company’s key verticals, contract balances, remaining performance obligations, and significant judgments and estimates. The expected impact may change as the Company finalizes its overall assessment.

Leases — Effective January 1, 2019, the Company will be required to adopt the new guidance of ASC Topic 842, Leases (with early adoption permitted effective January 1, 2018.) This amendment supersedes previous accounting guidance (Topic 840) and requires all leases, with the exception of leases with a term of twelve months or less, to be recorded on the balance sheet as lease assets and lease liabilities. The standard requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. The transition guidance in Topic 842 also provides specific guidance for the amounts previously recognized in accordance with the business combinations guidance for leases. The Company has not yet completed its assessment of the impact of the new guidance on its consolidated financial statements, when it will adopt the standard, or concluded on whether it will elect to apply practical expedients.

Measurement of Credit Losses on Financial Instruments — Effective January 1, 2020, the Company will be required to adopt the amended guidance of ASC Topic 326, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , (with early adoption permitted effective January 1, 2019.) The amendments in this update change how companies measure and recognize credit impairment for many financial assets. The new expected credit loss model will require companies to immediately recognize an estimate of credit losses expected to occur over the remaining life of the financial assets (including trade receivables) that are in the scope of the update. The update also made amendments to the current impairment model for held-to-maturity and available-for-sale debt securities and certain guarantees. Entities are required to adopt the standard using a modified-retrospective approach through a cumulative effect adjustment to retained earnings as of the beginning of the period of adoption. The Company has not yet completed its assessment of the impact of the new guidance on its consolidated financial statements or concluded on when it will adopt the standard.

Derivatives and Hedging — Effective January 1, 2019, with early adoption permitted in any interim or annual period, the Company will be required to adopt ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities . The new guidance is intended to simplify and amend hedge accounting and reporting to better align and disclose the economic results of an entity’s risk management activities in its financial statements. The ASU makes more financial and non-financial hedging strategies eligible for hedge accounting. It also changes how companies assess effectiveness and amends the presentation and disclosure requirements by eliminating the requirement to separately measure and report hedge ineffectiveness and generally requires companies, for qualifying hedges, to present the entire change in the fair value of a hedging instrument in the same income statement line as the hedged item. The guidance also eases documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. Currently, the Company does not apply hedge accounting.

Summary of Results of Operations

The following table presents a summary of our results of operations for the three and nine months ended September 30, 2017 and 2016 :



	Three Months Ended September 30,										Nine Months Ended September 30,
	2017					2016					2017					2016

Diluted earnings per share	$	0.77				$	0.49				$	1.90				$	1.40

The key highlights of our consolidated results for the three and nine months ended September 30, 2017 , as compared to the corresponding periods of 2016 , were as follows:


•	Revenues for the third quarter of 2017 were $377.5 million , or a 26.6% increase from $298.3 million reported last year, aided by $5.8 million or 2.0% of improved currency translation as compared to last year.

•

Income from operations grew 45.3% and 25.5% during the three and nine months ended September 30, 2017 , respectively, as compared to the corresponding periods last year. Expressed as a percentage of revenues, income from operations for the third quarter of 2017 was 13.0% compared to 11.4% last year, and 11.5% and 11.4% for the first nine months of 2017 and 2016, respectively. This increase of 1.6% for the third quarter of 2017 compared to the same period of 2016 was principally due to a $3.7 million decrease in acquisition-related stock-based compensation expenses and the improvement in utilization.

•

Our effective tax rate was 15.7% in the third quarter of 2017 compared to 21.3% in the third quarter of last year. The income tax provision for the third quarter of 2017 included $2.6 million of credits associated with excess tax benefits upon vesting or exercise of equity awards following the adoption of ASU 2016-09 on January 1, 2017 which drove an improvement in the effective tax rate of 5.2% .

•

Net income increased 62.9% to $42.6 million for the three months ended September 30, 2017 , compared to $26.2 million reported in the corresponding period last year. Expressed as a percentage of revenues, net income was 11.3% , an increase of 2.5% compared to 8.8% reported in the corresponding period of 2016 . This was largely driven by the decrease in stock-based compensation expense accompanied by a decrease in foreign exchange loss and and an improved effective tax rate.


•	Diluted earnings per share increased by $0.28 to $0.77 in the third quarter of 2017 compared to the third quarter of 2016.


•	Cash provided by operations increased $12.8 million , or 11.5% , to $124.0 million during the nine months ended September 30, 2017 as compared to the corresponding period last year.

The operating results in any period are not necessarily indicative of the results that may be expected for any future period.

Critical Accounting Policies

The discussion and analysis of our financial position and results of operations is based on our condensed consolidated financial statements which have been prepared in accordance with U.S. GAAP. The preparation of these condensed consolidated financial statements in accordance with U.S. GAAP requires us to make estimates and judgments that may affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On a recurring basis, we evaluate our estimates and judgments, including those related to revenue recognition and related allowances, impairments of long-lived assets including intangible assets and goodwill, income taxes including the valuation allowance for deferred tax assets, and stock-based compensation. Actual results may differ materially from these estimates under different assumptions and conditions. In addition, our reported financial condition and results of operations could vary due to a change in the application of a particular accounting standard.

Table of Contents

Other than as discussed below, there have been no material changes to our critical accounting policies or in the underlying accounting assumptions and estimates used in such policies in the three and nine months ended September 30, 2017 . For further information, refer to our summary of significant accounting policies and estimates in our Annual Report on Form 10-K filed for the year ended December 31, 2016.

Goodwill and Other Intangible Assets — We assess goodwill for impairment as of October 31 each year or more frequently if events or changes in circumstances indicate that the fair value of a reporting unit has been reduced below its carrying value. Effective January 1, 2017, we early-adopted ASU 2017-04 which simplifies the subsequent measurement of goodwill by removing the requirement to calculate the implied fair value of goodwill when measuring an impairment. As a result, when conducting our annual goodwill impairment assessment, we use a two-step process. The first step is to perform an optional qualitative evaluation as to whether it is more likely than not that the fair value of a reporting unit is less than its carrying value using an assessment of relevant events and circumstances. In performing this assessment, we are required to make assumptions and judgments including but not limited to an evaluation of macroeconomic conditions as they relate to our business, industry and market trends, as well as the overall future financial performance of a reporting unit and future opportunities in the markets in which it operates. If we determine that it is not more likely than not that the fair value of our reporting unit is less than its carrying value, we are not required to perform any additional tests in assessing goodwill for impairment. However, if we conclude otherwise or elect not to perform the qualitative assessment, we perform a second step consisting of a quantitative assessment of goodwill impairment. This quantitative assessment requires us to estimate impairment by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized 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.

Historically, a significant portion of the purchase consideration related to our acquisitions was allocated to customer relationships. In valuing customer relationships, we typically utilize the multi-period excess earnings method, a form of the income approach. The principle behind this method is that the value of the intangible asset is equal to the present value of the after-tax cash flows attributable to the intangible asset only. We amortize our intangible assets that have finite lives using either the straight-line method or, if reliably determinable, the pattern in which the economic benefit of the asset is expected to be consumed utilizing expected discounted future cash flows. Amortization is recorded over the estimated useful lives that predominantly range from five to ten years. We do not have any intangible assets with indefinite useful lives.

We review our intangible assets subject to amortization to determine if any adverse conditions exist or a change in circumstances has occurred that would indicate impairment or a change in the remaining useful life. If the carrying value of an asset exceeds its undiscounted cash flows, we will write down the carrying value of the intangible asset to its fair value in the period identified. In assessing fair value, we must make assumptions regarding estimated future cash flows and discount rates. If these estimates or related assumptions change in the future, we may be required to record impairment charges. If the estimate of an intangible asset’s remaining useful life is changed, we will amortize the remaining carrying value of the intangible asset prospectively over the revised remaining useful life.

Stock-Based Compensation — Stock-based compensation expense relating to the issuance of share-based awards to employees is based on the fair value of the award at the date of grant which is expensed over the requisite service period, net of estimated forfeitures. Equity-based awards that do not require future service are expensed immediately.

Adjusting stock-based compensation expense for estimated forfeitures requires judgment. If we change our assumptions, stock-based compensation expense may differ significantly from what we have recorded in the past.

Stock-based compensation expense in a period could be impacted, favorably or unfavorably, by differences between forfeiture estimates and actual forfeitures. If there are any modifications or cancellations of the equity-based awards, we may be required to accelerate, decelerate, increase or decrease any remaining unvested stock-based compensation expense.

Equity-based awards that do not meet the criteria for equity classification are recorded as liabilities and adjusted to fair value based on the closing price of our stock at the end of each reporting period. Future stock-based compensation expense related to our liability-classified awards may increase or decrease as a result of changes in the market price of our stock, adding to the volatility in our operating results.

Adoption of ASU 2016-09 effective January 1, 2017 increased income tax expense volatility. Our future operating results will depend on the fluctuations in the stock price on the dates the awards vest or options are exercised and the magnitude of transactions occurring in each reporting period, among other factors.

Change in Presentation of Certain Financial Information — As part of our discussion and analysis, we analyze revenues by client location and by vertical. Prior to the first quarter of 2017, management did not include reimbursable expenses and other revenues in its discussion of revenue performance across locations and verticals. Effective in the first quarter of 2017, we have allocated reimbursable expenses and other revenues (which primarily include travel and entertainment costs chargeable to clients) to corresponding geographies and verticals. We believe this change allows us to more effectively analyze our verticals and geographies by streamlining the presentation of revenues, both internally and externally, using a standardized approach. These changes did not result in any adjustments to our previously issued financial statements and were applied retrospectively beginning on January 1, 2015. Comparative information for the three and nine months ended September 30, 2016 is presented in the following tables:

(1)	CIS, which stands for the Commonwealth of Independent States, includes revenue from Belarus, Kazakhstan, Russia and Ukraine. APAC, which stands for Asia Pacific, includes revenue from southeast Asia, India and Australia.


(2)	Includes reimbursable expenses of $4,134 and $3,159 for the three months ended September 30, 2017 and 2016 , respectively; and $12,226 and $8,731 for the nine months ended September 30, 2017 and 2016 , respectively.

During the three months ended September 30, 2017 , our total revenues grew 26.6% over the corresponding period in 2016 to $377.5 million . This growth is attributable to our ability to retain and increase the level of services we provide to our existing customers and our ability to produce revenues from new customer relationships. We continue expanding our presence in various verticals, both organically and through acquisitions.

During the three months ended September 30, 2017 , revenues in our largest geography, North America, were $218.1 million , growing 28.4% over the corresponding period in 2016 . Revenues from this geography accounted for 57.8% of total revenues in the third quarter of 2017, an increase of 0.9% from 56.9% reported in the corresponding period last year. During the nine months ended September 30, 2017 , revenues in the North America geography were $613.4 million , growing 26.5% over the corresponding period in 2016. We realized double digit growth from all of the verticals in the North American geography for the three and nine months ended September 30, 2017 , as compared to the corresponding period last year. Revenues from the Media and Entertainment, Financial Services, and Emerging verticals increased greater than 30% for both the three and nine months ended September 30, 2017 as compared to the corresponding period last year.

Revenues in our Europe geography were $135.5 million during the three months ended September 30, 2017 , an increase of $25.2 million or 22.8% over $110.3 million in the corresponding period last year. Revenues in this geography accounted for 35.9% of consolidated revenues in the third quarter of 2017 as compared to 37.0% last year. During the nine months ended September 30, 2017 , revenues in the Europe geography were $371.0 million , growing 19.8% over the corresponding period in 2016. Europe experienced strong growth of greater than 50% from each of the Media and Entertainment, Life Sciences and Healthcare, and Emerging verticals during the three and nine months ended September 30, 2017 as compared to the corresponding periods last year. Revenues in the Travel and Consumer vertical grew 15.6% and 22.9% during the three and nine months ended September 30, 2017 , respectively, as compared to the same period last year. The Financial Services vertical, the largest in the Europe geography, experienced 8.6% and 2.3% growth in revenue for the three and nine months ended September 30, 2017 , respectively, as compared to the corresponding periods last year. Excluding revenues from our top customer, the Financial Services vertical grew 16.3% and 15.0% for the three and nine months ended September 30, 2017 , respectively, compared to the corresponding periods last year.

During the three months ended September 30, 2017 , revenues in the CIS geography were $16.0 million increasing $4.9 million over the corresponding period of 2016. The revenue increase in the CIS geography came predominantly from customers in the Financial Services, Software and Hi-Tech, and Emerging verticals. The CIS region also benefited from currency fluctuations which contributed 9.9% to the growth in reported revenues in this geography in the third quarter of 2017 as compared to the same period last year. Ongoing economic and geo-political uncertainty in the region and the volatility of the Russian ruble can significantly impact reported revenue in this geography.

During the third quarter of 2017 , revenues from the APAC region increased by $0.9 million , or 12.6% , over the corresponding period of 2016 . We continue to remain focused on diversifying our business beyond the Financial Services vertical in the APAC region and revenues outside of this vertical now represent 51.2% of total revenues in the APAC geography in the third quarter of 2017 compared to 39.8% in the corresponding period last year.

Cost of Revenues (Exclusive of Depreciation and Amortization)

Our cost of revenues (exclusive of depreciation and amortization) consists primarily of salaries, employee benefits, stock-based compensation expense, project related travel costs and fees for subcontractors that are assigned to client projects. Salaries and other compensation expenses of our revenue generating professionals are reported as cost of revenues regardless of whether the employees are actually performing client services during a given period.

We manage the utilization levels of our professionals through strategic hiring and efficient staffing of projects. Some of our IT professionals are specifically hired and trained to work for specific clients or on specific projects and some of our offshore development centers are dedicated to specific clients or projects. Our staff utilization also depends on the general economy and its effect on our clients and their business decisions regarding the use of our services.

During the three months ended September 30, 2017 , cost of revenues (exclusive of depreciation and amortization) was $239.4 million representing an increase of 25.5% from $190.8 million reported in the corresponding period of 2016 . The increase was primarily due to an increase in compensation costs largely driven by the 13.1% growth in the average number of production headcount during the three months ended September 30, 2017 as compared to the same period in 2016 as well as 2.8% impact from appreciation of foreign currencies. Expressed as a percentage of revenues, cost of revenues (exclusive of depreciation and amortization) was 63.4% and 64.0% in the third quarter of 2017 and 2016, respectively.

During the nine months ended September 30, 2017 , cost of revenues (exclusive of depreciation and amortization) was $667.2 million representing an increase of 23.8% from $539.0 million reported in the corresponding period of 2016 . The increase was primarily due to an increase in compensation costs largely driven by the 14.7% growth in the average number of production headcount during the nine months ended September 30, 2017 as compared to the same period in 2016 as well as 1.6% impact from appreciation of foreign currencies. Expressed as a percentage of revenues, cost of revenues (exclusive of depreciation and amortization) was 63.5% and 63.7% during the first nine months of 2017 and 2016, respectively.

Selling, General and Administrative Expenses

Selling, general and administrative expenses represent expenses associated with promoting and selling our services and general and administrative functions of our business. These expenses include the costs of salaries and fringe benefits, stock-based compensation, commissions, travel, legal and audit services, insurance, operating leases, advertising and other promotional activities. In addition, we pay a membership fee of 1% of revenues generated in Belarus to the administrative organization of the Belarus Hi-Tech Park.

During the three months ended September 30, 2017 , selling, general and administrative expenses were $81.2 million representing an increase of 20.3% as compared to $67.5 million reported in the corresponding period of 2016 . Expressed as a percentage of revenue, selling, general and administrative expenses decreased 1.1% to 21.5% for the three months ended September 30, 2017 as compared to the same period from the prior year. The increase in selling, general and administrative expenses was driven by a number of factors, including a $9.8 million increase in personnel-related costs excluding stock-based compensation expense and a $3.9 million increase in spend on facilities and infrastructure to support the increased headcount. These costs were offset by a $3.7 million decrease in acquisition-related stock-based compensation expenses.

During the nine months ended September 30, 2017 , selling, general and administrative expenses were $240.1 million representing an increase of 24.2% as compared to $193.2 million reported in the corresponding period of 2016 . Expressed as a percentage of revenue, selling, general and administrative expenses did not change and remained at 22.8% for the nine months ended September 30, 2017 as compared to the same period from the prior year. The increase was primarily driven by a $24.7 million increase in personnel-related costs including higher stock–based compensation expense and a $12.3 million increase in spend on facilities and infrastructure to support the increased headcount.

Depreciation and Amortization Expense

During the three and nine months ended September 30, 2017 , depreciation and amortization expense was $7.2 million and $20.9 million as compared to $5.9 million and $17.2 million in the corresponding periods last year. The increase in depreciation and amortization expense is primarily due to the increase in computer equipment to support headcount growth. Depreciation and amortization expense includes amortization of acquired intangible assets, all of which have finite useful lives. Expressed as a percentage of revenues, depreciation and amortization expense remained consistent during the three and nine months ended September 30, 2017 as compared to the corresponding periods of 2016 .

Interest and Other Income, Net

Net interest and other income was $1.4 million and $2.8 million during the three and nine months ended September 30, 2017 , respectively, representing an increase of $0.3 million and a decrease of $0.6 million compared to the corresponding periods last year.

Provision for Income Taxes

Determining the consolidated provision for income tax expense, deferred income tax assets and liabilities and related valuation allowance, if any, involves judgment. As a global company, we are required to calculate and provide for income taxes in each of the jurisdictions in which we operate.

In determining our quarterly provision for income taxes, we use an estimated annual effective tax rate which is based on expected annual profit before tax, statutory tax rates and tax planning opportunities available in the various jurisdictions in which we operate. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rates from quarter to quarter. Our effective tax rate was 15.7% and 15.2% for the three and nine months ended September 30, 2017 , respectively, and 21.3% and 21.1% for the three and nine months ended September 30, 2016 . The change in the effective tax rate during 2017 was primarily due to the adoption of a new accounting standard in the first quarter of 2017 whereby excess tax benefits of $2.6 million and $8.5 million were recognized for the three and nine months ended September 30, 2017 , respectively, in the income tax provision rather than additional paid-in-capital.

As we continue to grow our onsite presence and expand the geographic footprint of our delivery centers, this may result in volatility in our effective tax rate. We will also consider other factors that may contribute, favorably or unfavorably, to the overall effective tax rate in 2017 and beyond. These factors include statutory tax rate changes proposed in the countries that are part of our geographic footprint and excess tax benefits upon vesting or exercise of equity awards.

Foreign Exchange Gain /Loss

For discussion of the impact of foreign exchange fluctuations see “Item 3. Quantitative and Qualitative Disclosures About Market Risk.”

Effects of Inflation

Economies in CIS countries, particularly Belarus, Russia, Kazakhstan and Ukraine, have periodically experienced high rates of inflation. Periods of higher inflation may slow economic growth in those countries and as a result negatively impact the business of our existing clients and decrease demand for our services. We do not rely on borrowed funds for operations in those locations; therefore, increases in interest rates typical for inflationary environments do not currently pose a risk to our business. Inflation may increase some of our expenses such as wages.

While inflation may impact our results of operations and financial condition and it is difficult to accurately measure the impact of inflation, we believe the effects of inflation on our results of operations and financial condition are not significant.

Results by Business Segment

Our operations consist of four reportable segments: North America, Europe, Russia and Other. There were no operations in the Other segment for the periods presented. The segments represent components of EPAM for which separate financial information is available and is used on a regular basis by our chief executive officer, who is also our chief operating decision maker to determine how to allocate resources and evaluate performance. Our CODM makes business decisions based on segment revenues and operating profit. Segment operating profit is defined as income from operations before unallocated costs. Generally, operating expenses for each reportable segment have similar characteristics and are subject to similar factors, pressures and challenges as we use globally integrated support organizations to realize economies of scale and efficient use of resources. Expenses included in segment operating profit consist principally of direct selling and delivery costs as well as an allocation of certain shared services expenses and facilities costs. These shared expenses include Delivery, Recruitment and Development, Sales and Marketing, and support functions such as IT, Finance, Legal, and Human Resources. Generally, shared expenses are allocated based on measurable drivers of expense, e.g., recorded hours or headcount. Certain expenses that are not controllable at the segment level are not allocated to specific segments and such expenses are reported as deductions against the Company’s total income from operations.

Table of Contents

Our reportable segments are based on managerial responsibility for a particular client. Because managerial responsibility for a particular client relationship generally correlates with the client’s geographic location, there is a high degree of similarity between client locations and the geographic boundaries of our reportable segments. In some specific cases, however, managerial responsibility for a particular client is assigned to a management team in another region, usually based on the strength of the relationship between client executives and particular members of our senior management team. In such cases, the client’s activity would be reported through the management team’s reportable segment.

Segment revenues from external clients and segment operating profit, before unallocated expenses, for the North America, Europe, and Russia reportable segments for the three and nine months ended September 30, 2017 and 2016 were as follows:

Liquidity and Capital Resources

Capital Resources

Cash generated from operations has historically been our primary source of liquidity to fund operations and investments to grow our business. As of September 30, 2017 , our principal sources of liquidity were cash and cash equivalents totaling $512.5 million and $273.7 million of available borrowings under our revolving line of credit.

The Company’s U.S. operations historically have generated and are expected to continue to generate substantial cash flows. In the United States, we believe the combination of our cash on hand, cash inflows and ability to borrow under the existing debt arrangements continues to be sufficient to fund our current domestic operations and obligations. Additionally, we believe we have access to the credit and equity markets and could borrow additional funds under acceptable terms and conditions or raise additional capital through an equity transaction.

Many of our operations are conducted outside the United States and significant portions of our total cash are held internationally. As of September 30, 2017 , $386.0 million of our cash and cash equivalents, time deposits and restricted cash was held outside the United States and of this amount, $183.7 million was held in U.S. dollar denominated accounts in Belarus. As of September 30, 2017 , our Cyprus subsidiary had a balance of $29.5 million U.S. dollars held in the United Kingdom. Our subsidiaries in the CIS and APAC regions had a total of $8.4 million of cash and cash equivalents, time deposits and restricted cash balances denominated in currencies other than U.S. dollars.

The cash and cash equivalents held at locations outside of the United States are for future operating needs and we have no intention of repatriating those funds. As part of our ongoing liquidity assessments, we regularly monitor the mix of domestic and international cash flows and cash balances and we may decide to repatriate some or all of our funds to the United States. If we decide to remit funds to the United States in the form of dividends, $385.0 million would be subject to foreign withholding taxes, of which $329.0 million would also be subject to U.S. corporate income tax.

Our ability to expand and grow our business in accordance with current plans and to meet our long-term capital requirements will depend on many factors, including the rate at which our cash flows increase, our continued intent not to repatriate earnings from outside of the U.S. and the availability of public and private debt and equity financing. To the extent we pursue one or more significant strategic acquisitions, we may incur debt or sell additional equity to finance those acquisitions.

(1)	We estimate our future obligations for interest on our floating rate 2017 Credit Facility by assuming the weighted average interest rates in effect on each floating rate debt obligation at September 30, 2017 remain constant into the future. This is an estimate, as actual rates will vary over time. In addition, for the 2017 Credit Facility, we assume that the balance outstanding as of September 30, 2017 remains the same for the remaining term of the agreement. The actual balance outstanding under our 2017 Credit Facility may fluctuate significantly in future periods, depending on the availability of cash flow from operations and future investing and financing considerations.
(2)	We estimate our future obligations for long-term incentive plan payouts by assuming the price per share of our common stock in effect at September 30, 2017 remains constant into the future. This is an estimate as actual prices will vary over time.

Letters of credit

As of September 30, 2017 , we had two irrevocable standby letters of credit totaling $1.3 million under the 2017 Credit Facility, which are required to secure commitments for certain insurance policies and office rent. The letters of credit expire on April 27, 2018 and August 20, 2018 with a possibility of automatic extension for an additional period of one year from the present or any future expiration date.

Future Capital Requirements

We believe that our existing cash and cash equivalents combined with our expected cash flow from operations will be sufficient to meet our projected operating and capital expenditure requirements for at least the next twelve months and that we possess the financial flexibility to execute our strategic objectives, including the ability to make acquisitions and strategic investments in the foreseeable future. However, our ability to generate cash is subject to our performance, general economic conditions, industry trends and other factors. To the extent that existing cash and cash equivalents and operating cash flow are insufficient to fund our future activities and requirements, we may need to raise additional funds through public or private equity or debt financing. If we issue equity securities in order to raise additional funds, substantial dilution to existing stockholders may occur. If we raise cash through the issuance of additional indebtedness, we may be subject to additional contractual restrictions on our business. There is no assurance that we would be able to raise additional funds on favorable terms or at all.

Off-Balance Sheet Commitments and Arrangements

We do not have any obligations under guarantee contracts or other contractual arrangements that would constitute off-balance sheet arrangements other than as disclosed in Note 4 and Note 8 of our condensed consolidated financial statements in “Part I. Item 1. Financial Statements (Unaudited).” We have not entered into any transactions with unconsolidated entities whereby we have financial guarantees, subordinated retained interests, derivative instruments, or other contingent arrangements that expose us to material continuing risks, contingent liabilities, or any other obligation under a variable interest in an unconsolidated entity that provides financing, liquidity, market risk, or credit risk support to us, or engages in leasing, hedging, or research and development services with us.

Forward-Looking Statements

This quarterly report on Form 10-Q contains estimates and forward-looking statements, principally in “Part I. Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Part II. Item 1A. Risk Factors.” Our estimates and forward-looking statements are mainly based on our current expectations and estimates of future events and trends, which affect or may affect our businesses and operations. Although we believe that these estimates and forward-looking statements are based upon reasonable assumptions, they are subject to several risks and uncertainties and are made in light of information currently available to us. Important factors, in addition to the factors described in this quarterly report, may adversely affect our results as indicated in forward-looking statements. You should read this quarterly report and the documents that we have filed as exhibits hereto completely and with the understanding that our actual future results may be materially different from what we expect. The words “may,” “will,” “should,” “could,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “intend,” “potential,” “might,” “would,” “continue” or the negative of these terms or other comparable terminology and similar words are intended to identify estimates and forward-looking statements. Estimates and forward-looking statements speak only as of the date they were made, and, except to the extent required by law, we undertake no obligation to update, to revise or to review any estimate and/or forward-looking statement because of new information, future events or other factors. Estimates and forward-looking statements involve risks and uncertainties and are not guarantees of future performance. As a result of the risks and uncertainties described above, the estimates and forward-looking statements discussed in this quarterly report might not occur and our future results, level of activity, performance or achievements may differ materially from those expressed in these forward-looking statements due to, including, but not limited to, the factors mentioned above, and the differences may be material and adverse. Because of these uncertainties, you should not place undue reliance on these forward-looking statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to certain market risks in the ordinary course of our business. These risks result primarily from changes in concentration of credit risks, interest rates and foreign currency exchange rates. In addition, our international operations are subject to risks related to differing economic conditions, changes in political climate, differing tax structures, and other regulations and restrictions.

Concentration of Credit and Other Credit Risks

Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash and cash equivalents, trade accounts receivable and unbilled revenues.

We maintain our cash and cash equivalents and short-term investments with financial institutions. We believe that our credit policies reflect normal industry terms and business risk. We do not anticipate non-performance by the counterparties. We hold a significant balance of cash in banks in CIS countries where banking and other financial systems generally do not meet the banking standards of more developed markets and bank deposits made by corporate entities in the CIS region are not insured. As of September 30, 2017 , $225.8 million of total cash was held in CIS countries, of which $183.8 million was held in Belarus. The CIS banking sector remains subject to periodic instability and the transparency of the banking sector lags behind international standards. Particularly in Belarus, a banking crisis, bankruptcy or insolvency of banks that process or hold our funds, may result in the loss of our deposits or adversely affect our ability to complete banking transactions in the region, which could adversely affect our business and financial condition. Cash in other CIS locations is used for short-term operational needs and cash balances in those banks move with the needs of the entities.

Accounts receivable and unbilled revenues are generally dispersed across our clients in proportion to their revenues. As of September 30, 2017 , unbilled revenues from one customer, Expedia , individually exceeded 10% and accounted for 10.9% of our unbilled revenues. As of September 30, 2017 , accounts receivable from one customer, UBS AG , individually exceeded 10% and accounted for 10.5% of our accounts receivable as of September 30, 2017 .

There were no customers that accounted for more than 10% of total revenues during the three and nine months ended September 30, 2017 . During the three and nine months ended September 30, 2016 , revenues from one customer, UBS AG , were $35.1 million and $106.9 million , respectively, and accounted for more than 10% of total revenues. Indicated revenues include reimbursable expenses.

Historically, credit losses and write-offs of trade accounts receivable balances have not been material to our condensed consolidated financial statements.

Interest Rate Risk

Our exposure to market risk is mainly influenced by the changes in interest rates received on our cash and cash equivalent deposits and paid on any outstanding balance on our borrowings, mainly under our 2017 Credit Facility, which is subject to a variety of rates depending on the type and timing of funds borrowed. We do not believe we are exposed to material direct risks associated with changes in interest rates related to these borrowings.

We have not been exposed to material risks due to changes in market interest rates and we do not use derivative financial instruments to hedge our risk of interest rate volatility. However, our future interest expense may increase and interest income may fall due to changes in market interest rates.

Foreign Exchange Risk

Our global operations are conducted predominantly in U.S. dollars. Other than U.S. dollars, we generate a significant portion of our revenues in various currencies, principally, euros, British pounds, Canadian dollars, Swiss francs and Russian rubles and incur expenditures principally in Hungarian forints, Russian rubles, Polish zlotys, Swiss francs, British pounds, Indian rupees and Chinese yuan renminbi associated with the location of our delivery centers.

Our international operations expose us to foreign currency exchange rate changes that could impact translations of foreign denominated assets and liabilities into U.S. dollars and future earnings and cash flows from transactions denominated in different currencies. We are exposed to fluctuations in foreign currency exchange rates primarily on accounts receivable and unbilled revenues from sales in foreign currencies and cash outflows for expenditures in foreign currencies. Our results of operations, primarily revenues and expenses denominated in foreign currencies, can be affected if any of the currencies which we use materially in our business appreciate or depreciate against the U.S. dollar. Additionally, to the extent that we need to convert U.S. dollars into foreign currencies for our operations, appreciation of such foreign currencies against the U.S. dollar would adversely affect the amount of such foreign currencies we receive from the conversion.

Impact from foreign exchange was slightly unfavorable during the quarter ended September 30, 2017 and resulted in a loss of $0.1 million for the quarter compared to a loss of $1.7 million reported in the corresponding period last year. For the nine months ended September 30, 2017 , foreign exchange loss decreased $3.8 million to $1.5 million compared to the same period in 2016. The improvement in foreign exchange impact was primarily driven by movements in exchange rates relative to local currencies in our foreign operations, particularly Russian rubles and British pounds.

Management supplements results reported in accordance with United States generally accepted accounting principles, referred to as GAAP, with non-GAAP financial measures. Management believes these measures help illustrate underlying trends in our business and uses the measures to establish budgets and operational goals, communicated internally and externally, for managing our business and evaluating its performance. When important to management’s analysis, operating results are compared on the basis of “constant currency”, which is a non-GAAP financial measure. This measure excludes the effect of foreign currency exchange rate fluctuations by translating the current period revenues and expenses into U.S. dollars at the weighted average exchange rates of the prior period of comparison.

During the third quarter of 2017, we reported revenue growth of 26.6% over the third quarter of 2016. Had our consolidated revenues been expressed in constant currency terms using the exchange rates in effect during the third quarter of 2016, we would have reported revenue growth of 24.6% . The currency impact was primarily related to the depreciation of the British pound and, to a lesser extent, the euro relative to the U.S. dollar, partially offset by the appreciation of the Russian ruble.

During the quarter ended September 30, 2017 , approximately 36.4% of consolidated revenues and 40.9% of operating expenses were denominated in currencies other than the U.S. dollar. We are monitoring the developments relating to Brexit as we have a significant operating presence in the U.K. and collect revenues and incur expenses in currencies that may be affected.
