BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Jun. 30, 2023
Accounting Policies [Abstract]
BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES EPAM Systems, Inc. (the “Company” or “EPAM”) is a leading digital transformation services and product engineering company, providing digital platform engineering and software development services to customers located around the world, primarily in North America, Europe, and Asia. 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 several other industries. The Company is incorporated in Delaware with headquarters in Newtown, 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, 2022 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 unaudited 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, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position as of June 30, 2023 and the results of its operations and its cash flows for the periods presented. Risks and Uncertainties — As a result of its global operations, the Company may be subject to certain inherent risks. Concentration of Credit — Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents, short-term investments and trade receivables. The Company maintains cash, cash equivalents and short-term investments with financial institutions. The Company believes its credit policies reflect normal industry terms and business risk and there is no expectation of non-performance by the counterparties. The Company has cash in several countries, including Ukraine, Belarus and Russia, which have been impacted by the invasion of Ukraine and 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, 2023, the Company had $50.9 million of cash and cash equivalents in banks in Ukraine, $38.5 million of cash and cash equivalents in banks in Belarus, and $24.8 million of cash and cash equivalents in banks in Russia. Cash in Ukraine and Belarus is used for the operational needs of the local entities and cash balances change with the expected operating needs of these entities. The Company regularly monitors cash held in these countries and, to the extent the cash held exceeds amounts required to support its operations in these countries, the Company distributes the excess funds into markets with more developed banking sectors to the extent it is possible to do so. Due to restrictions imposed by the Russian government, our ability to distribute excess funds from Russia to other countries is limited. The Company places its cash and cash equivalents with financial institutions considered stable in the region, limits the amount of credit exposure with any one financial institution and conducts ongoing evaluations of the credit worthiness of the financial institutions with which it does business. However, a banking crisis, bankruptcy or insolvency of banks that process or hold the Company’s funds, or sanctions may result in the loss of deposits or adversely affect the Company’s ability to complete banking transactions, which could adversely affect the Company’s business and financial condition. See Note 2 “Impact of the Invasion of Ukraine” for further discussion of the Company’s response to the invasion of Ukraine and sale of its operations in Russia. Trade receivables are generally dispersed across many customers operating in different industries; therefore, concentration of credit risk is limited. Historically, credit losses and write-offs of trade receivables have not been material to the consolidated financial statements. If any of the Company’s customers enter bankruptcy protection or otherwise take steps to alleviate their financial distress, the Company’s credit losses and write-offs of trade receivables could increase, which would negatively impact its results of operations. Foreign currency risk — The Company’s global operations are conducted predominantly in U.S. dollars. Other than U.S. dollars, the Company generates revenues in various currencies, principally, euros, British pounds, Swiss francs and Canadian dollars and incurs expenditures principally in euros, Polish zlotys, Indian rupees, British pounds, Swiss francs, Hungarian forints, Mexican pesos, Canadian dollars, Colombian pesos and Chinese yuan renminbi. The Company’s international operations expose it to risk of adverse fluctuations in foreign currency exchange rates through the remeasurement of foreign currency denominated assets and liabilities (both third-party and intercompany) and translation of earnings and cash flows into U.S. dollars. 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 Polish zloty, Indian rupee and Hungarian forint transactions. See Note 6, “Derivative Financial Instruments ” for further discussion regarding the Company’s termination of the hedging program for the Russian ruble. Interest rate risk — The Company is exposed to market risk from changes in interest rates. Exposure to interest rate risk results primarily from variable rates related to cash and cash equivalent deposits, short-term investments and the Company’s borrowings, mainly under the 2021 Credit Agreement, which is subject to a variety of rates depending on the type and timing of funds borrowed (See Note 8 “Debt”). The Company does not believe it is exposed to material direct risks associated with changes in interest rates related to these deposits, investments and borrowings. Adoption of New Accounting Standards There were no recently adopted accounting standards which had a material impact on the Company’s consolidated financial position, results of operations, changes in stockholders’ equity and cash flows. 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. 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.

As of June 30, 2023, the Company had $67.7 million of Property and equipment, net in Ukraine consisting of a building classified as construction-in-progress located in Kyiv with a net book value of $51.5 million, laptops with a net book value of $9.5 million, most of which are in the possession of employees, various office furniture, equipment and supplies with a net book value of $5.1 million, and leasehold improvements located throughout Ukraine with a net book value of $1.6 million. Additionally, as of June 30, 2023, the Company had Operating lease right-of-use assets located throughout Ukraine with a net book value of $9.7 million. Through the issuance date of these interim financial statements, the Company is not aware of any damage to its long-lived assets in Ukraine and the Company expects to continue to use these assets as part of its global delivery model. On March 4, 2022, the Company announced a $100.0 million humanitarian commitment to support its employees and their families in and displaced from Ukraine. This humanitarian commitment is in addition to donations from EPAM's customers and employees and the work of EPAM volunteers on the ground. During the three and six months ended June 30, 2023, the Company expensed $3.9 million and $10.0 million, respectively, related to this commitment, which included special cash payments to support impacted employees, financial and medical support for impacted families, travel, meals and lodging expenses, and donations to third-party humanitarian organizations. Of the expensed amount for the three and six months ended June 30, 2023, $2.9 million and $5.3 million, respectively, is classified in Cost of revenues (exclusive of depreciation and amortization), and $1.0 million and $4.7 million, respectively, is classified in Selling, general and administrative expense on the condensed consolidated financial statements. During the three and six months ended June 30, 2022, the Company expensed $8.4 million and $34.0 million, respectively, related to this commitment, which included special cash payments to support impacted employees, financial and medical support for impacted families, travel, meals and lodging expenses, and donations to third-party humanitarian organizations. Of this expensed amount for the three and six months ended June 30, 2022, $3.3 million and $22.4 million, respectively, is classified in Cost of revenues (exclusive of depreciation and amortization), and $5.1 million and $11.6 million, respectively, is classified in Selling, general and administrative expense on the condensed consolidated financial statements. As of June 30, 2023, the Company has $45.2 million remaining to be expensed under this humanitarian commitment. The Company executed its business continuity plans following the invasion to assist relocating employees residing in Ukraine and the surrounding region impacted by the war and geopolitical uncertainty to other countries and to assign delivery personnel in locations outside of the region to serve in unbilled standby or backup capacities to ensure the continuity of delivery for its customers who have substantial delivery exposure to Ukraine or other delivery concerns resulting from the invasion and ongoing war. In addition to costs incurred as part of EPAM’s humanitarian commitment to Ukraine, during the three and six months ended June 30, 2023 the Company incurred expenses of $2.0 million and $9.4 million, respectively, related to these standby resources, classified as Cost of revenues (exclusive of depreciation and amortization). Also, during the three and six months ended June 30, 2023 the Company incurred expenses of $0.2 million and $0.4 million, respectively, related to its geographic repositioning efforts, classified as Selling, general and administrative expenses. During the three and six months ended June 30, 2022, the Company incurred expenses of $9.3 million and $11.8 million, respectively, related to these standby resources, classified as Cost of revenues (exclusive of depreciation and amortization) and $14.4 million and $33.1 million, respectively, related to its geographic repositioning efforts, classified as Selling, general and administrative expenses. During the six months ended June 30, 2022, the Company also recorded an impairment charge of $1.3 million, classified as Interest and other income, net related to a financial asset in Ukraine which the Company believed to be unrealizable due to the events in Ukraine. In response to the attacks on Ukraine, EPAM announced on March 4, 2022, it would discontinue services to customers located in Russia. Based on this change in facts and circumstances, the long-term cash flow forecast for the Company’s operations in Russia and its Russia reporting unit were significantly reduced. The reduction in the long-term cash flow forecasts indicated that the carrying amounts of goodwill and long-lived assets associated with the Company’s Russia reporting unit and operations in Russia may not be recoverable, and the carrying value of these assets was tested for impairment. The Company relied on the income approach to estimate the fair values of the Russia reporting unit and long-lived assets and considered multiple scenarios including the continuing operation and exit of operations in Russia. Reflecting the negative long-term cash flow forecasts that each of these scenarios produced for these assets, during the three months ended March 31, 2022, the Company recorded impairments of Property and equipment, net of $15.1 million, Operating lease right-of-use assets, net of $3.8 million, and Goodwill of $0.7 million. These asset impairment charges are included in Selling, general and administrative expenses in the condensed consolidated financial statements for the six months ended June 30, 2022. Additionally, the Company evaluated trade receivables and contract assets for estimated future credit losses from customers located in Russia and recorded a bad debt expense of $8.2 million reflecting the deterioration of creditworthiness of its customers in Russia during the six months ended June 30, 2022. Amounts recorded to bad debt expense during the three and six months ended June 30, 2023 and three months ended June 30, 2022 related to customers located in Russia were not material. On April 7, 2023, the Company amended and restated the agreement to sell substantially all of its remaining holdings in Russia to a third party. The timing and completion of the sale is subject to customary closing conditions, including regulatory approvals by the Russian and U.S. governments. The requisite regulatory approvals from the Russian government were received during the second quarter of 2023; however, the U.S. government had not provided the requisite approvals as of June 30, 2023. Due to the significant uncertainty of obtaining the necessary regulatory approvals as of June 30, 2023, the Company did not believe a sale was probable to be completed as of June 30, 2023 and has not reported the assets and liabilities to be sold as held for sale in its condensed consolidated balance sheet. Subsequent to June 30, 2023, the Company received the required approvals from the U.S. government to proceed with the sale and, on July 26, 2023, the sale of the remaining holdings in Russia was completed. The Company expects to record a loss on sale of approximately $18.4 million during the third quarter of 2023, including the recognition of the accumulated currency translation loss related to this subsidiary currently included in Accumulated other comprehensive loss. As of June 30, 2023, the Company had the following assets and liabilities in Russia: Cash and cash equivalents $ 24,451 Trade receivables and contract assets, net of allowance of $4,232 3,986 Prepaid and other current assets 264 Total assets in Russia $ 28,701 Accounts payable $ 88 Accrued compensation and benefits expenses 3,369 Accrued expenses and other current liabilities 1,169 Operating lease liabilities, current 86 Other noncurrent liabilities 51 Total liabilities in Russia $ 4,763

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The Company carries certain assets and liabilities at fair value on a recurring basis on its condensed consolidated balance sheets. The following tables present the fair values of the Company’s financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2023 and December 31, 2022: As of June 30, 2023 Balance Level 1 Level 2 Level 3 Foreign exchange derivative assets $ 14,137 $ — $ 14,137 $ — Total assets measured at fair value on a recurring basis $ 14,137 $ — $ 14,137 $ — Foreign exchange derivative liabilities $ 10 $ — $ 10 $ — Contingent consideration 13,000 — — 13,000 Total liabilities measured at fair value on a recurring basis $ 13,010 $ — $ 10 $ 13,000 As of December 31, 2022 Balance Level 1 Level 2 Level 3 Foreign exchange derivative assets $ 12,191 $ — $ 12,191 $ — Rights to acquire noncontrolling interest in consolidated subsidiaries 334 — — 334 Total assets measured at fair value on a recurring basis $ 12,525 $ — $ 12,191 $ 334 Foreign exchange derivative liabilities $ 9,350 $ — $ 9,350 $ — Contingent consideration 24,308 — — 24,308 Total liabilities measured at fair value on a recurring basis $ 33,658 $ — $ 9,350 $ 24,308 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 6 “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 businesses 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 agreements 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 rates used to determine the fair value of contingent consideration both as of June 30, 2023 and December 31, 2022, were at a maximum of 20.0%, if a rate was applied. 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 condensed consolidated statement of income. A reconciliation of the beginning and ending balances of Level 3 contingent consideration using significant unobservable inputs for the six months ended June 30, 2023 is as follows: Amount Contingent consideration as of January 1, 2023 $ 24,308 Changes in fair value of contingent consideration included in Interest and other income, net 1,514 Payment of contingent consideration for previously acquired businesses (12,844) Effect of foreign currency exchange rate changes, net 22 Contingent consideration as of June 30, 2023 $ 13,000 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 condensed 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 condensed 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: Fair Value Hierarchy Balance Estimated Fair Value Level 1 Level 2 Level 3 June 30, 2023 Financial Assets: Cash equivalents: Money market funds $ 207,273 $ 207,273 $ 207,273 $ — $ — Time deposits 120,950 120,950 — 120,950 — Total cash equivalents $ 328,223 $ 328,223 $ 207,273 $ 120,950 $ — Restricted cash $ 1,858 $ 1,858 $ 1,858 $ — $ — Time deposits included in Short-term investments $ 71,376 $ 71,376 $ — $ 71,376 $ — Financial Liabilities: Borrowings under the 2021 Credit Agreement $ 25,000 $ 25,000 $ — $ 25,000 $ — Deferred consideration for asset acquisition $ 54,807 $ 54,807 $ — $ 54,807 $ — Fair Value Hierarchy Balance Estimated Fair Value Level 1 Level 2 Level 3 December 31, 2022 Financial Assets: Cash equivalents: Money market funds $ 312,321 $ 312,321 $ 312,321 $ — $ — Total cash equivalents $ 312,321 $ 312,321 $ 312,321 $ — $ — Restricted cash $ 2,292 $ 2,292 $ 2,292 $ — $ — Time deposits included in Short-term investments $ 60,336 $ 60,336 $ — $ 60,336 $ — Financial Liabilities: Borrowings under the 2021 Credit Agreement $ 25,000 $ 25,000 $ — $ 25,000 $ — Deferred consideration for asset acquisition $ 53,636 $ 53,636 $ — $ 53,636 $ — During the year ended December 31, 2022, the Company completed an asset acquisition of software licenses for use in the regular course of business for a purchase price of $66.1 million, which included an upfront payment of $13.3 million and fixed deferred consideration, payable in annual installments, with an acquisition-date fair value of $52.8 million. To estimate fair value, the future payments were discounted to present value using a discount rate based on the estimated borrowing rate of the Company. The weighted average discount rate used to determine the acquisition-date fair value was 5.2%. See Note 13 “Commitments and Contingencies” for more information regarding the deferred consideration. Non-Marketable Securities Without Readily Determinable Fair Values The Company holds investments in equity securities that do not have readily determinable fair values. These investments are recorded at cost and are remeasured to fair value based on certain observable price changes or impairment events as they occur. The carrying amount of these investments was $30.3 million and $28.4 million as of June 30, 2023 and December 31, 2022, respectively, and is classified as Other noncurrent assets in the Company’s condensed consolidated balance sheets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS In the normal course of business, the Company 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 Polish zloty, Indian rupee and Hungarian forint transactions. During the three months ended March 31, 2022, in response to the invasion of Ukraine, the Company de-designated its Russian ruble foreign exchange forward contracts as hedges and entered into offsetting foreign exchange forward contracts with the same counterparty. The Company determined it was probable the underlying forecasted foreign currency transactions which were hedged would not occur and reclassified the accumulated loss of $43.9 million on the underlying hedges into income which is classified as foreign exchange loss in the condensed consolidated statement of income. As of June 30, 2023, all of the Company’s Russian ruble foreign exchange forwards contracts had settled. As of June 30, 2023, 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.

Leases [Abstract]
LEASES	LEASESThe Company leases office space, corporate apartments, office equipment, and vehicles. 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 right-of-use assets and associated lease liabilities and are recognized in the period in which the obligation for such payments is incurred. The Company’s leases have remaining lease terms ranging from 0.1 to 8.6 years. Certain lease agreements, mainly for office space, include options to extend or terminate the lease before the expiration date. The Company considers such options when determining the lease term when it is reasonably certain that the Company will exercise that option. The Company leases and subleases a portion of its office space to third parties. Lease income and sublease income were immaterial for the three and six months ended June 30, 2023 and 2022. See Note 2 “Impact of the Invasion of Ukraine” for discussion of impairment of right-of-use assets in Russia.

As of June 30, 2023, $19.8 million of total remaining unrecognized stock-based compensation cost related to service-based liability-classified cash-settled RSUs, net of estimated forfeitures, is expected to be recognized over the weighted-average remaining requisite service period of 2.6 years. The liability associated with the service-based liability-classified RSUs as of June 30, 2023 and December 31, 2022, was $0.8 million and $10.2 million, respectively, and was classified as Accrued compensation and benefits expenses in the condensed consolidated balance sheets.

The purchase price is equal to 85% of the fair market value of a share of EPAM’s common stock on the first date of an offering or the date of purchase, whichever is lower. During the three and six months ended June 30, 2023, the ESPP participants purchased 77 thousand shares of common stock under the ESPP. During the three and six months ended June 30, 2022, the ESPP participants purchased 55 thousand shares of common stock under the ESPP. The Company recognizes compensation expense related to share issuances pursuant to the ESPP on a straight-line basis over the six-month offering period. For the three and six months ended June 30, 2023, the Company recognized $3.4 million and $6.5 million, respectively, of stock-based compensation expense related to the ESPP. For the three and six months ended June 30, 2022, the Company recognized $3.7 million and $5.4 million, respectively, of stock-based compensation expense related to the ESPP. As of June 30, 2023, total unrecognized stock-based compensation cost related to the ESPP was $4.3 million, which is expected to be recognized over a period of 0.3 years. Commitments for Future Equity Awards In connection with the Company’s acquisitions of businesses as discussed in Note 3 “Acquisitions”, EPAM enters into agreements that contractually commit it to granting equity awards at future dates. The agreements are unique to each acquisition and terms vary to specify the number of future awards to be issued or a monetary value that will be settled with equity awards valued at future stock prices. As of June 30, 2023, the Company has commitments to grant up to $26.2 million of equity awards with the number of awards to be determined based on future stock prices. These awards contain performance criteria that will determine the number of future awards to be issued and there is a service-based vesting requirement after the grant date associated with these awards. As these awards are considered granted for accounting purposes, in determining the expense, the Company adjusts the expected settlement based on the probability of achievement of the performance criteria. Related to these awards, the amount of stock-based compensation expense recorded in the condensed consolidated statements of income for the three months ended June 30, 2023 was not material. As of June 30, 2023, the Company has issued 2 thousand performance-based equity-classified RSUs which are not considered granted for accounting purposes as the future vesting conditions have not yet been determined. Share Repurchases On February 13, 2023, the Board of Directors authorized a share repurchase program for up to $500.0 million of the Company's outstanding common stock. EPAM may repurchase shares of its common stock on a discretionary basis from time to time through open market purchases, privately negotiated transactions or other means, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. The timing and total amount of stock repurchases will depend upon business, economic and market conditions, corporate and regulatory requirements, prevailing stock prices, and other considerations. The share repurchase program has a term of 24 months, may be suspended or discontinued at any time, and does not obligate the company to acquire any amount of common stock. During the three and six months ended June 30, 2023, the Company repurchased 195 thousand and 225 thousand shares of its common stock for $41.4 million and $49.9 million, respectively, in cash. All of the repurchased shares have been retired. As of June 30, 2023, a remaining balance of $450.1 million was available for purchases of the Company’s common stock under the share repurchase program authorized by the Company’s Board of Directors.

INCOME TAXES	Jun. 30, 2023
Income Tax Disclosure [Abstract]
INCOME TAXES	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 rates for the three months ended June 30, 2023 and 2022 were 20.0% and (114.9)%, respectively, and 19.8% and 5.8% during the six months ended June 30, 2023 and 2022, respectively. The Company’s effective tax rates benefited from excess tax benefits recorded upon vesting or exercise of stock-based awards of $7.4 million during each of the three months ended June 30, 2023 and 2022, respectively, and $13.4 million and $20.5 million during the six months ended June 30, 2023 and 2022, respectively. Additionally, during the three months ended June 30, 2022, the Company’s effective tax rate benefited from the recognition of one-time benefits of $7.2 million resulting from the Company’s decision to change the tax status and to classify certain of its foreign subsidiaries as disregarded entities for U.S. income tax purposes.

EARNINGS PER SHARE	Jun. 30, 2023
Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHAREBasic 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, unvested equity-settled RSUs and the stock to be issued under the Company’s ESPP. 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 Six Months Ended 2023 2022 2023 2022 Numerator for basic and diluted earnings per share: Net income $ 120,033 $ 18,604 $ 222,325 $ 108,323 Numerator for basic and diluted earnings per share $ 120,033 $ 18,604 $ 222,325 $ 108,323 Denominator: Weighted average common shares for basic earnings per share 57,993 57,240 57,848 57,078 Net effect of dilutive stock options, restricted stock units, restricted stock awards and stock issuable under the ESPP 1,188 1,780 1,392 1,903 Weighted average common shares for diluted earnings per share 59,181 59,020 59,240 58,981 Net income per share: Basic $ 2.07 $ 0.33 $ 3.84 $ 1.90 Diluted $ 2.03 $ 0.32 $ 3.75 $ 1.84 The number of shares underlying equity-based awards that were excluded from the calculation of diluted earnings per share as their effect would be anti-dilutive was 519 thousand and 389 thousand during the three and six months ended June 30, 2023, respectively. The number of shares underlying equity-based awards that were excluded from the calculation of diluted earnings per share as their effect would be anti-dilutive was 461 thousand and 299 thousand during the three and six months ended June 30, 2022, respectively.

COMMITMENTS AND CONTINGENCIES	Jun. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	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. Ukraine Humanitarian Commitment — On March 4, 2022, EPAM announced that it has established a $100.0 million humanitarian commitment to support its employees in Ukraine and their families. See Note 2 “Impact of the Invasion of Ukraine” for more information regarding commitments to humanitarian aid for Ukraine. Deferred Consideration — During the year ended December 31, 2022, the Company purchased software licenses for use in the regular course of business in exchange for an upfront payment and fixed, future annual payments due over the next 4 years. As of June 30, 2023, the undiscounted deferred consideration amounts owed totaled approximately $60.0 million and are expected to be paid as follows: $14.2 million during the remainder of 2023, $14.0 million in 2024, $15.1 million in 2025, and $16.7 million in 2026. Contractual Commitment — On March 31, 2023, the Company entered into a 5-year agreement for cloud services through which it committed to spending at least $75.0 million over the term of the agreement. The Company has the ability to cancel the commitment whereby it would incur a cancellation penalty of 20% of the remaining contractual commitment.

SEGMENT INFORMATION

SEGMENT INFORMATION	6 Months Ended
SEGMENT INFORMATION	Jun. 30, 2023
Segment Reporting [Abstract]
SEGMENT INFORMATION	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, certain taxes included in operating expenses, 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 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 and benefits. 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. 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. See Note 2 “Impact of the Invasion of Ukraine” for more information regarding the Company’s decisions to no longer serve customers in Russia and the subsequent decision to exit its operations in Russia. Revenues from external customers and operating profit/(loss), before unallocated expenses, by reportable segment for the three and six months ended June 30, 2023 and 2022, were as follows: Three Months Ended Six Months Ended 2023 2022 2023 2022 Segment revenues: North America $ 680,071 $ 723,657 $ 1,390,028 $ 1,411,368 Europe 483,442 451,944 976,589 903,914 Russia 6,693 19,260 14,530 51,193 Total segment revenues $ 1,170,206 $ 1,194,861 $ 2,381,147 $ 2,366,475 Segment operating profit/(loss): North America $ 131,660 $ 127,420 $ 254,491 $ 254,154 Europe 64,801 35,396 124,705 92,107 Russia (2,743) 1,662 (5,748) (17,822) Total segment operating profit $ 193,718 $ 164,478 $ 373,448 $ 328,439 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.

BUSINESS AND SUMMARY OF SIGNI_2

BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2023
Accounting Policies [Abstract]
Nature of Operations	EPAM Systems, Inc. (the “Company” or “EPAM”) is a leading digital transformation services and product engineering company, providing digital platform engineering and software development services to customers located around the world, primarily in North America, Europe, and Asia. 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 several other industries. The Company is incorporated in Delaware with headquarters in Newtown, Pennsylvania.
Basis of Presentation	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.
Use of Estimates	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 unaudited 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, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position as of June 30, 2023 and the results of its operations and its cash flows for the periods presented.
Concentration of Credit And Interest Rate Risk	Concentration of Credit — Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents, short-term investments and trade receivables. The Company maintains cash, cash equivalents and short-term investments with financial institutions. The Company believes its credit policies reflect normal industry terms and business risk and there is no expectation of non-performance by the counterparties. Interest rate risk — The Company is exposed to market risk from changes in interest rates. Exposure to interest rate risk results primarily from variable rates related to cash and cash equivalent deposits, short-term investments and the Company’s borrowings, mainly under the 2021 Credit Agreement, which is subject to a variety of rates depending on the type and timing of funds borrowed (See Note 8 “Debt”). The Company does not believe it is exposed to material direct risks associated with changes in interest rates related to these deposits, investments and borrowings.
Foreign currency risk	Foreign currency risk — The Company’s global operations are conducted predominantly in U.S. dollars. Other than U.S. dollars, the Company generates revenues in various currencies, principally, euros, British pounds, Swiss francs and Canadian dollars and incurs expenditures principally in euros, Polish zlotys, Indian rupees, British pounds, Swiss francs, Hungarian forints, Mexican pesos, Canadian dollars, Colombian pesos and Chinese yuan renminbi. The Company’s international operations expose it to risk of adverse fluctuations in foreign currency exchange rates through the remeasurement of foreign currency denominated assets and liabilities (both third-party and intercompany) and translation of earnings and cash flows into U.S. dollars. 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 Polish zloty, Indian rupee and Hungarian forint transactions.
Adoption of New Accounting Standards and Pending Accounting Standards	Adoption of New Accounting Standards There were no recently adopted accounting standards which had a material impact on the Company’s consolidated financial position, results of operations, changes in stockholders’ equity and cash flows. 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. 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.
Fair Value of Financial Instruments	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 6 “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 businesses 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 agreements 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 rates used to determine the fair value of contingent consideration both as of June 30, 2023 and December 31, 2022, were at a maximum of 20.0%, if a rate was applied. 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 condensed consolidated statement of income.
Non-Marketable Securities Without Readily Determinable Fair Values	Non-Marketable Securities Without Readily Determinable Fair ValuesThe Company holds investments in equity securities that do not have readily determinable fair values. These investments are recorded at cost and are remeasured to fair value based on certain observable price changes or impairment events as they occur.
