BUSINESS AND 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 customers located around the world, primarily in North America, Europe, Asia and Australia. The Company’s industry expertise includes financial services, travel and consumer, software and hi-tech, business information and media, life sciences and healthcare, as well as other emerging industries. The Company is incorporated in Delaware with headquarters in Newtown, PA.Pennsylvania.
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” or “U.S. GAAP”) and Article 10 of Regulation S-X under the Securities Exchange Act of 1934, as amended. The unaudited 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, 20182019 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 management’s 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.
As previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, certain amounts recorded in the prior-period consolidated statement of cash flows presented have been reclassified to conform to the current-period financial statement presentation. These reclassifications had no effect on previously reported results of operations.
Adoption of New Accounting Standards
Unless otherwise discussed below, the adoption of new accounting standards did not have ana material impact on the Company’s consolidated financial position, results of operations, changes in stockholders’ equity and cash flows.
Leases Measurement of Credit Losses on Financial Instruments— In FebruaryJune 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, LeasesAccounting Standards Update (“Topic 842”). The standard supersedes previously existing lease guidance (“Topic 840”ASU”) and requires entities to recognize all leases, with the exception2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of leases with a term of twelve months or less,Credit Losses on the balance sheet as right-of-use assets (“RoU Assets”) and lease liabilities. The guidance also changes disclosure requirements with a focus on providing information that will enable users of financial statements to assess the amount, timing and uncertainty of cash flows arising from leases.Financial Instruments.
The amendments in this update changed how companies measure and recognize credit impairment for many financial assets. The new credit loss model requires 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. The Company adopted Topic 842,326, effective January 1, 2019,2020, using the optional transitiona modified-retrospective approach which allows the Companythrough a cumulative effect adjustment to apply the provisionsretained earnings as of the standard at the effective date without adjusting the comparable periods and carry forward disclosures under previously existing guidance for those periods presented within the Company’s financial statements.
The Company determines if an arrangement is a lease or contains a lease at inception. The Company performs an assessment and classifies the lease as either an operating lease or a financing lease at the lease commencement date with a right-of-use asset and a lease liability recognized in the statement of financial position under both classifications. The Company does not have finance leases that are material to the Company’s condensed consolidated financial statements.
Lease liabilities are initially measured at the present value of lease payments not yet paid. The present value is determined by applying the readily determinable rate implicit in the lease or, if not available, the incremental borrowing ratebeginning of the lessee. The Company determines the incremental borrowing rateperiod of adoption. As a result of the lessee on a lease-by-lease basis by developing an estimated centralized U.S. dollar borrowing rate for a fully collateralized obligation with a term similar to the lease term, and adjusts the rate to reflect the incremental risk associated with the currency in which the lease is denominated. Lease agreements of the Company may include options to extend or terminate the lease and the Company includes such options in the lease term when it is reasonably certain that the Company will exercise that option. RoU Assets are recognized based on the initial measurement of the lease liabilities plus initial direct costs less lease incentives and, according to the guidance for long-lived assets, RoU Assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Lease expense for operating leases is recognized on a straight-line basis over the lease term.

The Company elected a practical expedient to account for lease and non-lease components together as a single lease component. The Company also elected the short-term lease recognition exemption for all classes of lease assets with an original term of twelve months or less. As part of the transition, the Company elected a package of practical expedients allowing it to carry forward historical accounting for any expired or existing contracts that are or contain lease contracts, including classification of such contracts and initial direct costs associated with them.
The adoption of Topic 842 on January 1, 2019 resulted in326, the recognition of RoU AssetsCompany recorded an immaterial reduction to its allowance for operating leases of $177,597doubtful accounts for trade receivables and operating lease liabilities of $173,863. The adoption of Topic 842 did not have an impact on the condensed consolidated statement of income and comprehensive income, condensed consolidated statement of changes in stockholders’ equity or the condensed consolidated statement of cash flows.
See Note contract assets6 “Leases” in the condensed consolidated interim financial statements for additional information regarding leases..
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.
Measurement of Credit Losses on Financial Instruments — Effective January 1, 2020, the Company will be required to adopt the amended guidance of FASB 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 and will adopt the standard on January 1, 2020.

During 2018, the Company adjusted initially recognized intangible assets acquired with Continuum and their useful livesfinancial services as well as recognized an additional intangible asset in the form of a favorable lease, removed a noncurrent liability associated with an initially recognized unfavorable lease and revised the initial fair value of contingent consideration. The Company also finalized a working capital adjustment that resulted in cash collection in the amount of $76 reducing the original amount of the net assets acquired. These adjustments resulted in a corresponding decrease to the originally recognized value of acquired goodwill. During the first quarter of 2019, the Company finalized the fair value of the assets acquired and liabilities assumed in the acquisition of Continuum and no additional adjustments were recorded.
For the acquisitions of Think and test IO, estimated fair values of the assets acquired and liabilities assumed remain provisional and based on the information that was available as of the acquisition dates. The Company expects to complete the purchase price allocations as soon as practicable but no later than one year from the acquisition dates. During the six months ended June 30, 2019, there were no adjustments recorded related to the estimated fair values of the assets acquired and liabilities assumed at the date of the acquisition of Think.
As of June 30, 2019, the following table presents the estimated fair values and useful livesadded $6,300 of intangible assets, acquired from Continuum, Think and test IO:

The foreign exchange derivatives are valued using pricing models and discounted cash flow methodologies based on observable foreign exchange data at the measurement date. See Note 5 “Derivative Financial Instruments” in the condensed consolidated interim financial statements for additional information regarding derivative financial instruments.

The fair value of the contingent consideration was determined using a probability-weighted expected return method and is based on the expected future payments to be made to the sellers of the acquired businesses in accordance with the provisions outlined in the respective purchase agreements. Although there is significant judgment involved, the Company believes its estimates and assumptions are reasonable. In determining fair value, the Company considered a variety of factors, including future performance of the acquired business using financial projections developed by the Company and market risk assumptions that were derived for revenue growth and earnings before interest and taxes. The Company estimated future payments using the earnout formula and performance targets specified in the purchase agreement and adjusted those estimates to reflect the probability of their achievement. Those weighted-average estimated future payments were then discounted to present value using a rate based on the weighted-average cost of capital of guideline companies. The discount rate used to determine the fair value of contingent consideration for the 2020 Acquisition was 17.5%. Changes in financial projections, market risk assumptions, discount rates or probability assumptions related to achieving the various earnout criteria would result in a change in the fair value of the recorded contingent liabilities. Such changes, if any, are recorded within Interest and other income, net in the Company’s consolidated statement of income and comprehensive income.
In connection with the Continuum acquisition, the Company committed to making a cash earnout payment subject to attainment of specified performance targets in the 12 months after the acquisition date. As of the acquisition date, the Company recorded a $2,400 contingent consideration liability related to this earnout payment and, subsequently, reduced this liability by $900 during the third quarter of 2018 and $396 during the second quarter of 2019 due to the change in its fair value. The Company extinguished the earnout obligation during the second quarter of 2019 by paying $1,104 in cash. In connection with the Think acquisition, the Company committed to making a cash earnout payment subject to attainment of specified performance targets in the 12 months after the acquisition date. As of the acquisition date, the Company recorded a $5,990 contingent consideration liability related to this earnout payment as contingent consideration and, subsequently, increased its fair value by $1,752 during the second quarter of 2019 due to the change in its fair value. See Note 2 “Acquisitions” in the condensed consolidated interim financial statements for additional information regarding business acquisitions.

Financial Assets and Liabilities Not Measured at Fair Value on a Recurring Basis
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 generally short maturities of certain assets and liabilities result 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. The following tables present the estimated fair values of the Company’s financial assets and liabilities not measured at fair value on a recurring basis as of the dates indicated:

5.DERIVATIVE FINANCIAL INSTRUMENTS
In the normal course of business, the companyCompany uses derivative financial instruments to manage the risk of fluctuations in foreign currency exchange rates. The Company has a hedging program whereby it enters into a series of foreign exchange forward contracts with durations of twelve months or less that are designated as cash flow hedges of forecasted Russian ruble, Polish zloty and Indian rupee transactions. As of June 30, 2019,March 31, 2020, all of the Company’s foreign exchange forward contracts were designated as hedges and there is no financial collateral (including cash collateral) required to be posted by the Company related to the foreign exchange forward contracts.
The fair value of derivative instruments on the Company’s consolidated balance sheets as of June 30, 2019March 31, 2020 and December 31, 20182019 were as follows:

The Company records changes in the fair value of its cash flow hedges in accumulated other comprehensive loss in the consolidated balance sheetsheets until the forecasted transaction occurs. When the forecasted transaction occurs, the Company reclassifies the related gain or loss on the cash flow hedge to cost of revenues (exclusive of depreciation and amortization). In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, the Company reclassifies the gain or loss on the related cash flow hedge into income. If the Company does not elect hedge accounting, or the contract does not qualify for hedge accounting treatment, the changes in fair value from period to period are recorded in income.

The changes in the fair value of foreign currency derivative instruments in our unaudited condensed consolidated statements of income and comprehensive income for the three and six months ended June 30,March 31, 2020 and 2019 and 2018 were as follows:

6. LEASES
6.LEASES
The Company leases office space, corporate apartments, office equipment, and vehicles. The Company leases office space in order to minimize risks associated with ownership such as fluctuations in real estate prices. The leasing of corporate apartments is used to minimize costs associated with business trips of Company personnel. Many of the Company’s leases contain variable payments including changes in base rent and charges for common area maintenance or other miscellaneous expenses. Due to this variability, the cash flows associated with these variable payments are not included in the minimum lease payments used in determining the RoU Assetsright-of-use assets and associated lease liabilities and are recognized in the period in which the obligation for such payments is incurred. The Company subleases a portion of its office space to third parties. The Company leases office equipment for those assets requiring extensive support including maintenance, repairs and replacement of obsolete parts. The Company leases vehicles in certain locations primarily as an employee benefit.
The Company’s leases have remaining lease terms ranging from 1 day0.1 years to 11.911.1 years. Certain lease agreements, mainly for office space, include options to extend or terminate the lease before the expiration date.

The number of awards to be issued is subject to attainment of specified performance targets in the 2 years after the acquisition date as well as the Company’s stock price at the time of formal issuance. The awards require continued service and vest over 3 years from the date of acquisition.

10.INCOME TAXES
In determining its interim provision for/(benefit from)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 rates for the three months ended June 30,March 31, 2020 and 2019 and 2018 were 16.6% and 12.0%, respectively, and 11.3% and (9.2)% during the six months ended June 30, 2019 and 2018,5.4%, respectively.
The Company’s effective tax rates benefited from excess tax benefits recorded upon vesting or exercise of stock-based awards of $4,741$11,697 and $5,440$11,513 during the three months ended June 30,March 31, 2020 and 2019, and 2018, respectively, and $16,254 and $10,130 during the six months ended June 30, 2019 and 2018, respectively.
The interim benefit from income taxes in the three and six months ended June 30, 2018 was favorably impacted by the recognition of $706 and $25,340, respectively, of net deferred tax assets resulting from the Company’s decision to change the tax status and to classify most of its foreign subsidiaries as disregarded for U.S. income tax purposes. This was partially offset by a provisional $2,157 increase in income taxes payable associated with the one-time transition tax on accumulated foreign subsidiary earnings not previously subject to U.S. income tax imposed by the Tax Cuts and Jobs Act (“U.S. Tax Act”) recorded in the first quarter of 2018 and impacting the six months ended June 30, 2018.
11.EARNINGS PER SHARE
Basic earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. For purposes of computing basic earnings per share, any nonvested shares of restricted stock that have been issued by the Company and are contingently returnable to the Company are excluded from the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing net 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:

12. COMMITMENTS AND CONTINGENCIES
12.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, infringement of third party intellectual property rights, data privacy violations, and certain tortious conduct in the course of providing services. The duration of these indemnifications varies, and in certain cases, is indefinite.
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 effect on the Company’s business, financial condition, results of operations or cash flows.
Building Acquisition Commitments — During the year ended December 31, 2019, the Company entered into an agreement to purchase office space in Ukraine intended to support the global delivery center in that country. The agreement is subject to completion of construction and other ordinary closing conditions. As of March 31, 2020, the Company has committed to making future payments totaling approximately $36,900 including VAT to the sellers upon transfer of the building.

13.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. 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 corporate expenses are not allocated to specific segments as these expenses are not controllable at the segment level. Such expenses include certain types of professional fees, non-corporate taxes, compensation to non-employee directors and certain other general and administrative expenses, including compensation of specific groups of non-production employees. In addition, the Company does not allocate amortization of acquisition-related intangible assets acquired through business combinations, goodwill and other asset impairment charges, stock-based compensation expenses, acquisition-related costs and certain other one-time charges. 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/(benefit from)for income taxes. Additionally, management has determined that it is not practical to allocate identifiable assets by segment since such assets are used interchangeably among the segments.
The Company manages its business primarily based on the managerial responsibility for its client base and market. As managerial responsibility for a particular customer relationship generally correlates with the customer’s geographic location, there is a high degree of similarity between customer locations and the geographic boundaries of the Company’s reportable segments. In some cases, managerial responsibility for a particular customer is assigned to a management team in another region and is usually based on the strength of the relationship between customer executives and particular members of EPAM’s senior management team. In such cases, the customer’s activity would be reported through the management team’s reportable segment.
During the fourth quarter of 2019, the Company changed its management reporting of segment revenue to exclude other income. Prior year amounts presented below have been changed to conform to the new presentation.

Revenues from external customers and operating profit, before unallocated expenses, by reportable segments for the three and six months ended June 30,March 31, 2020 and 2019, and 2018, were as follows:

Business Update Regarding COVID-19
During the first quarter of 2020, the spread of a new strain of coronavirus and the disease created by that virus, COVID-19, has created a global pandemic presenting substantial public health and economic challenges around the world. The global pandemic is affecting our employees, communities and business operations, as well as the global economy and financial markets. The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition will depend on future developments that are highly uncertain and cannot be accurately predicted, including new information that may emerge concerning COVID-19, the actions taken to contain it or treat its impact and the economic impact on local, regional, national and international markets.
The disclosure in the remainder of this Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is qualified by the disclosure in this section on the impacts of COVID-19 and, to the extent that the disclosure in the remainder of this MD&A refers to a financial or performance metric that has been affected by a trend or activity, that reference is in addition to any impact discussed in this section of the impacts of the COVID-19 pandemic. The effect of the COVID-19 pandemic is rapidly evolving and, as such, the information contained herein is accurate as of the date hereof, but may become outdated due to changing circumstances beyond our present awareness or control.

Our COVID-19 Pandemic Response
Our top priority during the COVID-19 pandemic continues to be the safety and well-being of our employees. As governments institute and relax restrictions on social distancing, commercial operations, and travel, we are working to ensure we comply with frequently changing requirements while maintaining the health and safety of our employees and our ability to continue to serve our customers during and after these challenging times. When COVID-19 first appeared in China and then as it spread globally, we rapidly implemented our business continuity plans to ensure the safety and well-being of more than 37,300 EPAM professionals, while continuing to support the operations of hundreds of customers around the world. As of May 6, 2020, approximately 96% of EPAM employees have switched to a secure and productive work from home delivery model with minimal service interruptions and in close collaboration with our customers.
Our Employees
Our senior leadership team is deeply engaged in keeping our employees safe. With the vast majority of our employees able to work productively from a remote location, we do not expect that social distancing requirements or restrictions on non-essential businesses will have a material adverse effect on our ability to operate our business or productively deliver services to our customers, nor on our financial reporting systems, internal control over financial reporting, or disclosure controls and procedures.
Restrictions on travel and immigration, including without limitation the April 22, 2020 Executive Order suspending some immigration into the United States for 60 days, may impact our operations. However, we do not believe that the immigration restrictions in place at this time or general travel restrictions initiated as a result of the COVID-19 pandemic will have a material adverse effect on our business or financial condition and we anticipate expediting immigration processing for our employees if and when the Executive Order is lifted.
Our Customers
Our traditional global delivery model, centralized support functions, and scale developed from shared fixed-cost resources enable us to deliver our services and solutions from our delivery centers to global customers across all geographies. The effective implementation of our business continuity plans allowed us to make the incremental change to deliver services and solutions to our customers from remote locations instead of from our delivery centers. We are committed to continuing to provide our customers with the products, services, and solutions they seek to deliver business results. We are working with our customers to assess their needs and future demand so that we can deploy resources accordingly and in compliance with local requirements for continued operations.
Despite our ability to productively provide our services and solutions remotely, deterioration in economic conditions for our customers could materially reduce our sales and profitability. Reduced demand from our customers or our customer’s customers, potential financial distress in our customer base due to deteriorating economic conditions, and volatile macroeconomic conditions could result in reduced sales and decreased collectability of accounts receivable which would negatively impact our results of operations. Based on currently available information and management’s current expectations, we believe that our revenues will decline in the second quarter of 2020 as compared to the first quarter of 2020. Depending on the duration of the COVID-19 pandemic and the timing and speed of economic recovery, reduced sales volume could extend beyond the second quarter of 2020.
Our Community
EPAM has a longstanding commitment to support the communities where we live and work and we have strengthened that commitment to assist our global and local communities by taking proactive measures, donating resources, and developing open source contributions to support COVID-19 relief efforts in our communities. EPAM and its employees have committed more than $1.0 million in resources, funds, personal protective equipment, materials, engineering services, and matching contributions to support COVID-19 healthcare and hunger relief efforts.

We are using our intellectual property, engineering roots, and design acumen to put technology to work towards understanding and fighting COVID-19. For example:
EPAM Continuum introduced the GENTL™ Mask, an open source solution for manufacturers designed to address the supply shortage of protective masks that medical professionals need amid the coronavirus outbreak.    
EPAM used its implementation services to help Curogram scale its two-way texting and video chat telemedicine platform to address the COVID-19 pandemic so that healthcare institutions can quickly deploy mass screening and testing services.
EPAM developed COVID Resistance, an open source mobile app that can be customized for specific countries or regions for digital contact-tracing that anonymously tracks risk exposure to COVID-19.
Moving Forward
There is uncertainty around the impacts the pandemic will have on our business, financial condition, and results of operations. We will continue to actively monitor our business and the needs of our employees, customers, and communities to determine the appropriate actions to protect the health and safety of our employees and our ongoing operations. This includes actions informed by the requirements and recommendations of federal, state and local authorities.
Economic and demand uncertainty in the current environment may impact our future results. We are monitoring the demand for our services including the duration and degree to which we will see declines or delays in new customer projects. We continue to assess how the effects of COVID-19 on the economy may impact human capital allocation, revenue, profitability, and operating expenses.

The key highlights of our consolidated results for the three and six months ended June 30, 2019,March 31, 2020, as compared to the corresponding periods of 2018,2019, were as follows:
Revenues for the secondfirst quarter of 20192020 were $551.6$651.4 million, or a 23.8%24.9% increase from $445.6$521.3 million reported in the same period last year. The secondfirst quarter of 20192020 was negatively impacted by $6.0$5.4 million or 1.3%1.1% due to changes in certain foreign currency exchange rates as compared to the corresponding period last year. Think and test IO acquisitionsAcquisitions completed within the prior 12 months contributed $4.0$11.0 million ofto our revenues toin the total revenues for the secondfirst quarter of 2019. Revenues for the first half of 2019 were $1,072.9 million, or a 23.4% increase from $869.8 million reported in the corresponding period last year. The first half of 2019 was negatively impacted by $20.4 million or 2.3% due to changes in certain foreign currency exchange rates as compared to the corresponding period last year. Think and test IO acquisitions contributed $7.9 million of revenues to the total revenues for the six months ended June 30, 2019.2020.
Income from operations grew 34.4% and 33.6%35.3% to $72.9 million and $137.5$87.5 million during the three and six months ended June 30, 2019, respectively,March 31, 2020, as compared to the corresponding periods in 2018.2019. Expressed as a percentage of revenues, income from operations for the secondfirst quarter of 20192020 was 13.2%13.4% compared to 12.2%12.4% in the secondfirst quarter last year and 12.8% and 11.8% for the first half of 2019 and 2018, respectively.year. The increase as a percentage of revenues for the first three months of 2020 was primarily driven by lower selling, general and administrative expenses as a percentage of revenuesassociated with stock-based compensation largely attributable to the mark-to-market for cash-settled RSUs as compared to the same period last year.
Our effective tax rate was 11.3% in the first sixthree months of 20192020 compared to (9.2)%5.4% in the corresponding period last year. The interim benefit fromOur effective tax rate during the period was impacted by lower excess tax benefits recorded upon vesting or exercise of stock-based awards as a percentage of pre-tax income taxes in the sixthree months ended June 30, 2018 was favorably impacted byMarch 31, 2020 as compared to the recognition of $25.3 million of net deferred tax assets resulting from the Company’s decision to change the tax status and to classify most of its foreign subsidiaries as disregarded for U.S. income tax purposes.corresponding period last year.
Net income increased 17.0%40.8% to $58.8$85.6 million for the three months ended June 30, 2019,March 31, 2020, compared to $50.3$60.8 million reported in the corresponding period last year. Expressed as a percentage of revenues, net income was 10.7%13.1%, a decreasean increase of 0.6%1.4% compared to 11.3%11.7% reported in the corresponding period of 2018.2019. This trendincrease is largely driven by the lower effective tax rate during the second quarter of 2018 partially offset by the improvement inhigher income from operations as a percentage of revenues. Net income grew 4.2%well as an improvement in foreign exchange gain/(loss) during the six months ended June 30, 2019 as compared to the corresponding period last year primarily due to the improvement in income from operations partially offset by the increase in our effective tax rate.first quarter of 2020.

This increase is largely driven by the improvement in net income as well as a $27.7 million benefit coming from delayed annual payments of certain variable compensation related to the prior performance year shifting into the second quarter of 2020 where similar payouts in 2019 occurred during the first quarter of 2019.
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, goodwill and right-of-use assets, 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.
Other than as discussed below, duringDuring the three and six months ended June 30, 2019,March 31, 2020, there have been no material changes to our critical accounting policies or in the underlying accounting assumptions and estimates used in such policies as reported in our Annual Report on Form 10-K for the year ended December 31, 2018.
Leases — The Company determines if an arrangement is a lease or contains a lease at inception. The Company performs an assessment and classifies the lease as either an operating lease or a financing lease at the lease commencement date with a right-of-use asset (“RoU Assets”) and a lease liability recognized in the statement of financial position under both classifications.

Lease liabilities are initially measured at the present value of lease payments not yet paid. The present value is determined by applying the readily determinable rate implicit in the lease or, if not available, the incremental borrowing rate of the lessee. The Company determines the incremental borrowing rate of the lessee on a lease-by-lease basis by developing an estimated centralized U.S. dollar borrowing rate for a fully collateralized obligation with a term similar to the lease term, and adjusts the rate to reflect the incremental risk associated with the currency in which the lease is denominated. Lease agreements of the Company may include options to extend or terminate the lease. The Company includes such options into the lease term when it is reasonably certain that the Company will exercise that option. RoU Assets are recognized based on the initial measurement of the lease liabilities plus initial direct costs less lease incentives. Lease expense for operating leases is recognized on a straight-line basis over the lease term. RoU Assets are subject to periodic impairment tests.
The Company has elected a practical expedient to account for lease and non-lease components together as a single lease component. In addition, the Company elected the short-term lease recognition exemption for all classes of lease assets.2019.

Revenues in the North American geography were negatively impacted by the reassignment of a certain customer’s revenues to the European geography as a result of a change in location where we serve that customer, along with a change in managerial responsibility for the customer relationship. Without this reassignment, revenue growth in North America would have been 32.0% and 34.4% for the three and six months ended June 30, 2019, respectively, compared to the same periods from the previous year.
The top three revenue contributing customer location countries in Europe were the United Kingdom, Switzerland and Netherlands, contributing $69.0$92.1 million, $35.4$47.2 million and $21.0$25.9 million, respectively, during the three months ended June 30, 2019.March 31, 2020.

Revenues in the European geography benefited from the reassignment of a certain customer’s revenues from North America as a result of a change in location where we serve that customer along with a change in managerial responsibility for the customer relationship. Without this reassignment, revenue growth in Europe would have been 8.8% and 7.4% for the three and six months ended June 30, 2019, respectively, compared to the same periods in the prior year.

During the three months ended June 30, 2019,March 31, 2020, revenues in the CIS geography included $22.5$22.0 million from customers in Russia, an increase of $5.6$6.1 million over the corresponding period of 2018.2019.

Cost of Revenues (Exclusive of Depreciation and Amortization)
The principal components of our cost of revenues (exclusive of depreciation and amortization) are salaries, bonuses, fringe benefits, stock-based compensation, expense, project-related travel costs and fees for subcontractors who are assigned to customer projects. Salaries and other compensation expenses of our revenue generatingdelivery professionals are reported as cost of revenues regardless of whether the employees are actually performing customer services during a given period. We manage the utilization levels of our professionals through strategic hiring and efficient staffing of projects. Our employees are a critical asset, necessary for our continued success and therefore we expect to continue hiring talented employees and providing them with competitive compensation programs.

During the three months ended June 30, 2019,March 31, 2020, cost of revenues (exclusive of depreciation and amortization) was $355.9$423.8 million representing an increase of 23.1%23.0% from $289.2$344.7 million in the corresponding period of 2018.2019. The increase was primarily due to an increase in compensation costs largely driven by the 19.4%20.2% growth in the average number of production professionals during the three months ended June 30, 2019March 31, 2020 as compared to the same period in 20182019, partially offset by a 1.7%2.4% favorable impact from changing foreign currency exchange rates. Expressed as a percentage of revenues, cost of revenues (exclusive of depreciation and amortization) remained stable at 64.5%was 65.1% and 64.9%66.1% in the secondfirst quarter of 2020 and 2019, and 2018, respectively.
During the six months ended June 30, 2019, cost of revenues (exclusive of depreciation and amortization) was $700.6 million representing an increase of 23.6% from $566.8 million in the corresponding period of 2018. The increase wasyear-over-year decrease is primarily due to an increasea decrease in stock-based compensation costsexpense largely attributable to the mark-to-market accounting for cash-settled RSUs granted to our delivery professionals, which is driven by the 18.8% growthmovements in the average number of production professionals and a higher level of accrued variable compensation during the first half of 2019 as compared to the same period in 2018 partially offset by a 3.1% favorable impact from changing foreign currency exchange rates. Expressed as a percentage of revenues, cost of revenues (exclusive of depreciation and amortization) remained stable at 65.3% and 65.2% for the first six months of 2019 and 2018, respectively.our stock price.
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, bonuses, fringe benefits, stock-based compensation, expense, severance, bad debt, travel, legal and auditaccounting services, insurance, facilities costs,including 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 High-Technologies Park. We expect our selling, general and administrative expenses to continue to increase in absolute terms as our business expands but generally to remain steady as a percentage of our revenues in the foreseeable future.
During the three months ended June 30, 2019,March 31, 2020, selling, general and administrative expenses were $111.8$125.1 million representing an increase of 19.8%22.9% as compared to $93.3$101.8 million in the corresponding period of 2018.2019. The increase in selling, general and administrative expenses was primarily driven by a $10.4$13.3 million increase in personnel-related costs including stock-based compensation, talent acquisition and development expenses and a $6.8$5.4 million increase in facilities and infrastructure relatedinfrastructure-related expenses to support our growth. Expressed as a percentage of revenues, selling, general and administrative expenses decreased 0.6%0.3% to 20.3%19.2% for the three months ended June 30, 2019March 31, 2020 as compared to the same period from the prior year, largely driven by lower bad debt expense and stock-based compensation expense as a percentage of revenues.
During the six months ended June 30, 2019, selling, general and administrative expenses were $213.5 million representing an increase of 16.7% as compared to $182.9 million reported in the corresponding period of 2018. Expressed as a percentage of revenues, selling, general and administrative expenses decreased 1.1% to 19.9% for the six months ended June 30, 2019 as compared to the same period from the prior year. The decrease was primarily driven by the slower growth of 18.0%decrease in personnel-related costs, including stock-based compensation expense as comparedlargely attributable to revenue growth of 23.4%.the mark-to-market accounting for cash-settled RSUs, which is driven by the movements in our stock price.

Depreciation and Amortization Expense
During the three and six months ended June 30, 2019,March 31, 2020, depreciation and amortization expense was $11.0$14.9 million, and $21.2 million, respectively, as compared to $9.0$10.2 million and $17.1 million, respectively in the corresponding period last year. The increase in depreciation and amortization expense is primarily the result of increased investment in computer equipment used by our employees and amortization of acquired intangible assets, all of which have finite useful lives. Expressed as a percentage of revenues, depreciation and amortization expense remained consistentincreased to 2.3% during the three and six months ended June 30, 2019March 31, 2020 as compared to the 2.0% in the corresponding periodsperiod of 2018.2019.

Provision for/(Benefit from)for Income Taxes
Determining the consolidated provision for income tax expense, deferred income tax assets and liabilities and any potential related valuation allowances involves judgment. We consider factors that may contribute, favorably or unfavorably, to the overall annual effective tax rate in the current year as well as the future. These factors include statutory tax rates and tax law changes in the countries where we operate and excess tax benefits upon vesting or exercise of equity awards as well as consideration of any significant or unusual items.  

As a global company, we are required to calculate and provide for income taxes in each of the jurisdictions in which we operate. Our effective tax rate was 16.6% and 11.3%provision for income taxes during the three and six months ended June 30,March 31, 2020 and 2019 respectively, and 12.0% and (9.2)%, respectively, for the three and six months ended June 30, 2018.
Our effective tax rates benefited from excess tax benefits recorded upon vesting or exercise of stock-based awards of $4.7$11.7 million and $16.3$11.5 million, duringrespectively. Our effective tax rate was 11.3% for the three and six months ended June 30, 2019, respectively,March 31, 2020, and $5.4 million and $10.1 million during5.4% for the three and six months ended June 30, 2018, respectively.

The interim benefit fromincrease in the effective tax rate is attributable to the decrease, as a percentage of income before provision for income taxes, in excess tax benefits recorded upon vesting or exercise of stock-based awards in the six months ended June 30, 2018 was favorably impacted byfirst quarter of 2020 as compared to the recognition of $25.3 million of net deferred tax assets resulting fromcorresponding period in the Company’s decision to change the tax status and to classify most of our foreign subsidiaries as disregarded for U.S. income tax purposes. This was partially offset by a provisional $2.2 million increase in income taxes payable associated with the one-time transition tax on accumulated foreign subsidiary earnings not previously subject to U.S. income tax imposed by the Tax Cuts and Jobs Act (“U.S. Tax Act”).

Results by Business Segment
Our operations consist of three reportable segments: North America, Europe, and Russia. The segments represent components of EPAM for which separate financial information is available and used on a regular basis by our chief executive officer, who is also our chief operating decision maker (“CODM”), 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. 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 corporate expenses are not allocated to specific segments as these expenses are not controllable at the segment level. Such expenses include certain types of professional fees, non-corporate taxes, compensation to non-employee directors and certain other general and administrative expenses, including compensation of specific groups of non-production employees. In addition, the Company does not allocate stock-based compensation, amortization of acquisition-related intangible assets acquired through business combinations, goodwill and other asset impairment charges, stock-based compensation expenses, acquisition-related costs and certain other one-time charges. These unallocated amounts are combined with total segment operating profit to arrive at consolidated income from operations.

We manage our business primarily based on the managerial responsibility for its client base and market. As managerial responsibility for a particular customer relationship generally correlates with the customer’s geographic location, there is a high degree of similarity between customer locations and the geographic boundaries of our reportable segments. In some cases, managerial responsibility for a particular customer is assigned to a management team in another region and is usually based on the strength of the relationship between customer executives and particular members of EPAM’s senior management team. In such cases, the customer’s activity would be reported through the management team’s reportable segment.
Segment revenues from external customers and segment operating profit, before unallocated expenses, for the North America, Europe and Russia reportable segments for the three and six months ended June 30,March 31, 2020 and 2019 and 2018 were as follows:

This increase reflects the impact from depreciationdecrease is primarily attributable to lower utilization, particularly in higher-cost geographies, and an elevated level of foreign currencies in which our global delivery centers operate.
During the six months ended June 30, 2019, revenues for the North America segment increased $153.4 million, or 31.4%, compared to the same period last year and segment operating profit increased $38.6 million, or 40.6%, compared to the same period last year. During the six months ended June 30, 2019 and 2018, revenues from our North America segment were 59.8% and 56.1% of total segment revenues, respectively. As a percentage of North America segment revenues, the North America segment’s operating profit margin increased to 20.9%costs associated with certain employee benefits during the six months ended June 30, 2019 from 19.5% in the corresponding periodfirst quarter of 2018. This increase reflects the impact from depreciation of foreign currencies in which our global delivery centers operate.
Revenues were negatively impacted by the reassignment of a certain customer to the Europe segment from the North America segment as a result of a change in managerial responsibility. Without this reassignment, North America segment growth would have been 34.3% and 36.7% for the three and six months ended June 30, 2019, respectively, compared to the corresponding periods of 2018.2020.

Currency fluctuations of the Russian ruble typically impact the results in the Russia segment. Ongoing economic and geo-politicalgeopolitical uncertainty in the region and the volatility of the Russian ruble can significantly impact reported revenues and operating profitsprofitability in this geography.segment. We continue to monitor geo-politicalgeopolitical forces, economic and trade sanctions, and other issues involving this region.
Effects of Inflation
Economies in some countries where we operate, particularly Belarus, Russia, Kazakhstan, Ukraine and India have periodically experienced high rates of inflation. Periods of higher inflation may affect various economic sectors in those countries and increase our cost of doing business there. 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.
Liquidity and Capital Resources
Capital Resources
Our cash generated from operations has been our primary source of liquidity to fund operations and investments to support the growth of our business. As of June 30, 2019,March 31, 2020, our principal sources of liquidity were cash and cash equivalents totaling $777.4$916.3 million as well as $274.6$274.7 million of available borrowings under our revolving credit facility.

We have cash in banks in Belarus, Russia, Ukraine, Kazakhstan, Armenia and Uzbekistan, where the banking sector remains subject to periodic instability, banking and other financial systems generally do not meet the banking standards of more developed markets and bank deposits made by corporate entities are not insured. As of June 30, 2019,March 31, 2020, the total amount of cash held in these countries was $217.5$233.3 million and, of this amount, $149.6$161.1 million was locatedheld in Belarus. Cash in this region is used for operational needs and cash balances in those banks change with the operating needs of our entities in the region. We regularly monitor cash held in these countries and, to the extent the cash held exceeds amounts required to support our business operations, we distribute the excess funds into markets with more developed banking sectors.
As of June 30, 2019,March 31, 2020, we had $274.6outstanding borrowings of $25.0 million available for borrowing under our revolving credit facility, and our outstanding debt of $25.0 million represents the minimal required borrowing to keep the credit facility active. As of June 30, 2019, we were in compliance with all covenants specified under the credit facility and we anticipate being in compliance for the foreseeable future. See Note 7 “Long-Term Debt” of our condensed consolidated financial statements in “Part I. Item 1. Financial Statements (Unaudited)” for information regarding our long-term debt.

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 or decrease and the availability of public and private debt and equity financing. We may require additional cash resources due to changed business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If our resources are insufficient to satisfy our cash requirements, we may seek to sell additional equity or debt securities or obtain another credit facility.
Based on currently available information and management’s current expectations, we anticipate that we have sufficient cash on hand and sufficient access to capital to continue to fund our operations for a significant period of time. However, COVID-19 and related measures to contain its impact have caused material disruptions in both national and global financial markets and economies. The future impact of COVID-19 and the COVID-19 containment measures cannot be predicted with certainty and may increase our borrowing costs and other costs of capital and otherwise adversely affect our business, results of operations, financial condition and liquidity.

Investing Activities
Net cash used in investing activities during the sixthree months ended June 30, 2019March 31, 2020 was $47.4$59.5 million compared to $68.3$18.6 million used in the same period in 2018.2019. During the first sixthree months of 2019,2020, the cash used in investing activities was primarily attributable to capital expenditures which decreased by $5.7of $29.1 million and acquisitions of businesses net of cash acquired of $10.3 million compared to the same period last year. Also,cash used for capital expenditures was $13.4 million during the first sixthree months of 2019, $16.2 million was used for the acquisition of test IO whereas during the first six months of 2018, $50.3 million of cash was used in investing activities related to the acquisition of Continuum.2019.

Net cash provided byused in financing activities was $8.2$2.0 million in the first sixthree months of 20192020 compared to $11.6$10.2 million provided in the same period of 2018.2019. During the first sixthree months of both 2019 and 2018,2020, net cash received from the exercises of stock options issued under our long-term incentive plans was $22.4 million.$6.9 million compared to $11.4 million received in the corresponding period of 2019. These cash inflows were partially offset by payments for the withholding taxes related to net share settlements of restricted stock units of $1.0 million in the first three months of 2020, compared to $1.2 million paid in corresponding period of 2019 and payment of $7.9 million of contingent consideration related to acquisition of Think.

Contractual Obligations and 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.factors including the impact of the COVID-19 pandemic as described elsewhere in this MD&A. 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.
There have been no material changes with respect to the contractual obligations disclosedSee Note 12 “Commitments and Contingencies” of our condensed consolidated financial statements in “Part I. Item 1. Financial Statements (Unaudited)” of this Quarterly Report and “Part II. Item 7. Contractual Obligations and Future Capital Requirements” of our Annual Report on Form 10-K for the year ended December 31, 2018.2019 for information regarding contractual obligations.

Item 1. Financial Statements (Unaudited).” We have not entered into any transactions with unconsolidated entities where 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.

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 primarily result from changes in concentration of credit, foreign currency exchange rates and interest rates. In addition, our international operations are subject to risks related to differing economic conditions, changes in political climates, 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 and trade accounts receivable and unbilled revenues.receivables.
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 and we do not anticipate non-performance by the counterparties. We have cash in banks in countries such as Belarus, Russia, Ukraine, Kazakhstan, Armenia and Uzbekistan, where the banking sector remains subject to periodic instability, banking and other financial systems generally do not meet the banking standards of more developed markets, and bank deposits made by corporate entities are not insured. As of June 30, 2019, $217.5March 31, 2020, $233.3 million of our total cash was kept in banks in these countries, of which $149.6$161.1 million was held in Belarus. In this region, and 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 this region is used for short-term operational needs and cash balances in those banks movechange with the operating needs of those entities.our entities in the region. We regularly monitor cash held in these countries and, to the extent the cash held exceeds amounts required to support our business operations, we distribute the excess funds into markets with more developed banking sectors.
Accounts receivable and unbilled revenuesTrade receivables are generally dispersed across many customers operating in different industries; therefore, concentration of credit risk is limited. There were nolimited and we do not believe significant credit risk existed at March 31, 2020. Though our results of operations depend on our ability to successfully collect payment from our customers individually exceeding 10%for work performed, historically, credit losses and write-offs of trade receivables have not been material to our consolidated financial statements. If any of our accounts receivable, unbilled revenuescustomers enter bankruptcy protection or total revenues asotherwise take steps to alleviate their financial distress resulting from the COVID-19 pandemic, our credit losses and write-offs of and for the three and six months ended June 30, 2019.trade receivables could increase, which would negatively impact our results of operations.
Interest Rate Risk
Our exposure to market risk is influenced by the changes in interest rates 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 deposits and borrowings.
Foreign Exchange Risk
Our global operations are conducted predominantly in U.S. dollars. Other than U.S. dollars, we generate revenues principally in euros, British pounds, Swiss francs, Canadian dollars and Russian rubles. Other than U.S. dollars, we incur expenditures principally in Russian rubles, Hungarian forints, Polish zlotys, British pounds, Swiss francs, euros, Indian rupees and Chinese yuan renminbi. As a result, currency fluctuations, specifically the depreciation of the euro, British pound, and Canadian dollar and the appreciation of the Russian ruble, Hungarian forint, Polish zloty, Chinese yuan renminbi and Indian rupee relative to the U.S. dollar, could negatively impact our results of operations.
During the quarter ended June 30, 2019,March 31, 2020, foreign exchange lossgain was $3.6$6.5 million compared to a gainloss of $1.8$3.5 million reported in the corresponding period last year. DuringThis improvement is largely driven by the six months ended June 30, 2019, foreign exchange loss was $7.0 million compared to a gaindevaluation of $1.6 million in the corresponding period last year.Russian Ruble during the first quarter of 2020.
During the quarter ended June 30, 2019,March 31, 2020, approximately 32.4%30.6% of consolidated revenues and 39.6%45.4% of consolidated operating expenses were denominated in currencies other than the U.S. dollar.
To manage the risk of fluctuations in foreign currency exchange rates and hedge a portion of our forecasted foreign currency denominated operating expenses in the normal course of business, we implemented a hedging program through which we enter into a series of foreign exchange forward contracts with durations of twelve months or less that are designated as cash flow hedges of forecasted Russian ruble, Polish zloty and Indian rupee transactions. As of June 30, 2019,March 31, 2020, the net unrealized gainloss from these hedges was $2.7$10.4 million.

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 secondfirst quarter of 2019,2020, we reported revenue growth of 23.8%24.9% over the secondfirst quarter of 2018.2019. Had our consolidated revenues been expressed in constant currency terms using the exchange rates in effect during the secondfirst quarter of 2018,2020, we would have reported revenue growth of 25.1%26.0%. TheOur revenues have been mainly impacted from theby depreciation of the euro, and British pound and Russian ruble relative to the U.S. dollar. During the secondfirst quarter of 2019,2020, we reported a net income increase of 17.0%40.8% over the secondfirst quarter of 2018.2019. Had our consolidated results been expressed in constant currency terms using the exchange rates in effect during the secondfirst quarter of 2018,2019, we would have reported a net income increase of 15.6%34.1%. Net income has been most positively impacted by depreciation of the Hungarian forint, Russian ruble and Polish zloty relative to the U.S. dollar partially offset by the depreciation of the euro and British pound relative to the U.S. dollar.
Item 4. Controls and Procedures
Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Based on management’s evaluation, with the participation of our Chief Executive Officer and Chief Financial Officer, as of the end of the period covered by this report, these officers have concluded that our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), are effective to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.
Changes in Internal Control Over Financial Reporting
There has been no change in our internal control over financial reporting during the quarter ended June 30, 2019March 31, 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
From time to time, we are involved in litigation and claims arising out of our operations in the normal course of business. We are not currently a party to any material legal proceeding, nor are we aware of any material legal or governmental proceedings pending or contemplated to be brought against us.
Item 1A. Risk Factors
There have been no material changes with respect toFor a discussion of our potential risks and uncertainties, see the risk factor below and the risk factors disclosed inunder the heading “Part I. Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019.
Our results of operations have been adversely affected and could in the future be materially adversely affected by the globalcoronavirus pandemic (COVID-19).
The global coronavirus pandemic (COVID-19) has created significant volatility in the price of our common stock, uncertainty in customer demand for our services, and widespread economic disruption. The extent to which the coronavirus pandemic will further impact our business, operations and financial results will depend on numerous factors that are frequently changing or unknown, and that we may not be able to accurately predict, including: the duration and scope of the pandemic; governmental, business and individuals’ responses or planned responses to the pandemic; the impact of the pandemic on economic activity and any interventions intended to mitigate decreased economic activity; the effect on our customers and customer demand for our products, services, and solutions; our ability to sell and provide our products, services, and solutions, including as a result of travel restrictions, personnel working from home or with diminished technology and communication abilities, and social distancing; the ability of our customers to pay timely, if at all, for our services and solutions with or without discounts requested by our customers; and closures of our and our customers’ offices and facilities. The closure of our customers’ facilities, restrictions that prevent our customers from accessing those facilities or their own customers, and broad disruptions in our customers’ markets and customer base, has disrupted, and could in the future disrupt the demand for our products, services, and solutions and result in, among other things, termination of customer contracts, delays or interruptions in the performance of contracts, losses of revenues, and an increase in bad debt expense. Customers may also slow or halt decision making, delay planned work, or suspend, terminate, or reduce existing contracts or services. Travel and immigration restrictions may delay or prevent our personnel from accessing worksites, and work-from-home or remote working arrangements could reduce profitability or increase information security and connectivity vulnerabilities. In addition, when COVID-19-related restrictions on business are eased, our ability to deliver services to our customers could be affected by any outbreak of illness among employees returning to our facilities or to our customers'
facilities. Moreover, there may be additional costs that we will have to incur in connection with further changes to, or a return
to, normal operating conditions. To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in the risk factors included in the Annual Report on Form 10-K for the year ended December 31, 2018.2019, including, but not limited to, those relating to our operations in emerging markets, our ability to execute on our growth strategy through strategic acquisitions, our dependency on third parties for network infrastructure, attracting, hiring, and retaining personnel, the effects on movements in foreign currency exchange rates, and the effects that changes to fiscal, political, regulatory and other federal policies may have on EPAM, each of which could materially adversely affect our business, financial condition, results of operations and/or stock price.
