Interim Condensed Consolidated Financial Statements	Interim Condensed Consolidated Financial Statements
	The terms “Cognizant,” “we,” “our,” “us” and “the Company” refer to Cognizant Technology Solutions Corporation unless the context indicates otherwise. We have prepared the accompanying unaudited condensed consolidated financial statements included herein in accordance with generally accepted accounting principles in the United States of America, or U.S. GAAP, and Article 10 of Regulation S-X under the Securities Exchange Act of 1934, as amended. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements (and notes thereto) included in our Annual Report on Form 10-K for the year ended December 31, 2014. In our opinion, all adjustments considered necessary for a fair presentation of the accompanying unaudited condensed consolidated financial statements have been included, and all adjustments are of a normal and recurring nature. Operating results for the interim periods are not necessarily indicative of results that may be expected to occur for the entire year.
	During the three months ended March 31, 2015, we repurchased 400,000 shares of our Class A common stock for $25.0 million, inclusive of fees and expenses, under our existing stock repurchase program approved by our Board of Directors. As of March 31, 2015, the remaining available balance under the Board authorization was $788.9 million. Additional stock repurchases were made in connection with our stock-based compensation plans, whereby company shares were tendered by employees for payment of applicable statutory tax withholdings. During the three months ended March 31, 2015, such repurchases totaled 217,014 shares at an aggregate cost of $13.4 million.
	New Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board, or FASB, issued a standard on revenue from contracts with customers. The new standard sets forth a single comprehensive model for recognizing and reporting revenue. The standard also requires additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. The new standard will be effective for periods beginning on or after January 1, 2017. Early adoption is not permitted. The standard allows for two methods of adoption: the full retrospective adoption, which requires the standard to be applied to each prior period presented, or the modified retrospective adoption, which requires the cumulative effect of adoption to be recognized as an adjustment to opening retained earnings in the period of adoption. We are currently evaluating the effect the new standard will have on our consolidated financial statements and related disclosures.
	In April 2015, the FASB issued a standard related to the presentation of debt issuance costs. The standard requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying value of that debt liability. The recognition and measurement guidance for debt issuance costs are not affected by this standard. The amendment is effective on a retrospective basis for fiscal years, and interim periods within those years, beginning on or after January 1, 2016. The adoption of this standard will affect financial statement presentation only and is expected to have no effect on our financial condition or results of operations.
	In April 2015, the FASB issued a standard providing guidance to customers in evaluating whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the standard requires the customer to account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer is required to account for the arrangement as a service contract. The amendments are effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2016. The Company is currently in the process of evaluating the impact of adoption of the standard on our consolidated financial statements.

	The unrealized losses for the above securities as of March 31, 2015 and December 31, 2014 are primarily attributable to changes in interest rates. As of March 31, 2015, we do not consider any of the investments to be other-than-temporarily impaired. The gross unrealized gains and losses in the above tables were recorded, net of tax, in accumulated other comprehensive income (loss).
	The contractual maturities of our fixed income available-for-sale investment securities as of March 31, 2015 are set forth in the following table:
		Amortized			Fair
Cost			Value

Asset-backed securities	219.9			220.1
Fixed income available-for-sale investment securities	$	1,505.90		$	1,509.30
Asset-backed securities were excluded from the maturity categories because the actual maturities may differ from the contractual maturities since the underlying receivables may be prepaid without penalties. Further, actual maturities of debt securities may differ from those presented above since certain obligations provide the issuer the right to call or prepay the obligation prior to scheduled maturity without penalty.
Proceeds from sales of available-for-sale investment securities and the gross gains and losses that have been included in earnings as a result of those sales were as follows:

	On November 20, 2014, we entered into a credit agreement with a commercial bank syndicate providing for a $1,000.0 million unsecured term loan and a $750.0 million unsecured revolving credit facility. The term loan was used to pay a portion of the cash consideration in connection with the 2014 acquisition of TZ US Parent, Inc., or TriZetto. The revolving credit facility is available for general corporate purposes. The term loan and the revolving credit facility both mature on November 20, 2019. As of March 31, 2015 and December 31, 2014, we had notes outstanding under the revolving credit facility of $100.0 million and $650.0 million, respectively. We are required under the credit agreement to make scheduled quarterly principal payments on the term loan.

	Our Indian subsidiaries, collectively referred to as Cognizant India, are primarily export-oriented and are eligible for certain income tax holiday benefits granted by the government of India for export activities conducted within Special Economic Zones, or SEZs, for periods of up to 15 years. Our Indian profits ineligible for SEZ benefits are subject to corporate income tax at the rate of 33.99%. In addition, all Indian profits, including those generated within SEZs, are subject to the Minimum Alternative Tax, or MAT, at the current rate of approximately 21.0%, including surcharges. Any MAT paid is creditable against future Indian corporate income tax, subject to limitations.
	Our effective income tax rates were as follows:
		Three Months Ended
		March 31,
		2015		2014
	Effective income tax rate	25	%	26.3	%
	For the 2015 and 2014 periods, the principal difference between our effective income tax rates and the U.S. federal statutory rate is the effect of the Indian tax holiday and earnings taxed in countries that have lower rates than the United States. In 2015, our effective income tax rate decreased primarily due to discrete tax benefits recorded in 2015.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	We measure our cash equivalents, investments and foreign exchange forward contracts at fair value. The authoritative guidance defines fair value as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions.
	The fair value hierarchy consists of the following three levels:
	•	Level 1 – Inputs are quoted prices in active markets for identical assets or liabilities.
	•	Level 2 – Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.
	•	Level 3 – Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.
	The following table summarizes our financial assets and (liabilities) measured at fair value on a recurring basis as of March 31, 2015:

	We measure the fair value of money market funds and U.S. Treasury securities based on quoted prices in active markets for identical assets and therefore classify these assets as Level 1. The fair value of commercial paper, certificates of deposit, U.S. government agency securities, municipal debt securities, U.S. and international corporate bonds and foreign government debt securities is measured based on relevant trade data, dealer quotes, or model driven valuations using significant inputs derived from or corroborated by observable market data, such as yield curves and credit spreads. We measure the fair value of our asset-backed securities using model driven valuations based on significant inputs derived from or corroborated by observable market data such as dealer quotes, available trade information, spread data, current market assumptions on prepayment speeds and defaults and historical data on deal collateral performance. The value of the mutual funds invested in fixed income securities is based on the net asset value, or NAV, of the fund, with appropriate consideration of the liquidity and any restrictions on disposition of our investment in the fund. The carrying value of the time deposits approximated fair value as of March 31, 2015 and December 31, 2014.
	We estimate the fair value of each foreign exchange forward contract by using a present value of expected cash flows model. This model calculates the difference between the current market forward price and the contracted forward price for each foreign exchange contract and applies the difference in the rates to each outstanding contract. The market forward rates include a discount and credit risk factor. The amounts are aggregated by type of contract and maturity.
	During the three months ended March 31, 2015 and the year ended December 31, 2014, there were no transfers among Level 1, Level 2, or Level 3 financial assets and liabilities.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments
	In the normal course of business, we use foreign exchange forward contracts to manage foreign currency exchange rate risk. The estimated fair value of the foreign exchange forward contracts considers the following items: discount rate, timing and amount of cash flow and counterparty credit risk. Derivatives may give rise to credit risks from the possible non-performance by counterparties. Credit risk is generally limited to the fair value of those contracts that are favorable to us. We have limited our credit risk by entering into derivative transactions only with highly-rated global financial institutions, limiting the amount of credit exposure with any one financial institution and conducting ongoing evaluation of the creditworthiness of the financial institutions with which we do business. In addition, all the assets and liabilities related to our foreign exchange forward contracts set forth in the below table are subject to International Swaps and Derivatives Association, or ISDA, master netting arrangements or other similar agreements with each individual counterparty. These master netting arrangements generally provide for net settlement of all outstanding contracts with the counterparty in the case of an event of default or a termination event. We have presented all the assets and liabilities related to our foreign exchange forward contracts on a gross basis, with no offsets, in our accompanying unaudited condensed consolidated statements of financial position. There is no financial collateral (including cash collateral) posted or received by us related to our foreign exchange forward contracts.
	The following table provides information on the location and fair values of derivative financial instruments included in our unaudited condensed consolidated statement of financial position as of:

	Cash Flow Hedges
	We have entered into a series of foreign exchange forward contracts that are designated as cash flow hedges of Indian rupee denominated payments in India. These contracts are intended to partially offset the impact of movement of exchange rates on future operating costs and are scheduled to mature each month during 2015, 2016, 2017, and 2018. Under these contracts, we purchase Indian rupees and sell U.S. dollars. The changes in fair value of these contracts are initially reported in the caption “Accumulated other comprehensive income (loss)” in our consolidated statements of financial position and are subsequently reclassified to earnings in the same period the hedge contract matures. As of March 31, 2015, we estimate that $40.7 million, net of tax, of the net losses related to derivatives designated as cash flow hedges recorded in accumulated other comprehensive income (loss) is expected to be reclassified into earnings within the next 12 months.
	The notional value of our outstanding contracts by year of maturity and the net unrealized (loss) included in accumulated other comprehensive income (loss) for such contracts were as follows as of:

	Net unrealized (loss) included in accumulated other comprehensive income (loss), net of taxes	$	(44.5	)		$	(86.7	)
	Upon settlement or maturity of the cash flow hedge contracts, we record the related gain or loss, based on our designation at the commencement of the contract, with the hedged Indian rupee denominated expense reported within cost of revenues and selling, general and administrative expenses. Hedge ineffectiveness was immaterial for all periods presented.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	Commitments and Contingencies
	We are involved in various claims and legal actions arising in the ordinary course of business. We accrue a liability when a loss is considered probable and the amount can be reasonably estimated. In the opinion of management, the outcome of any existing claims and legal or regulatory proceedings, if decided adversely, is not expected to have a material adverse effect on our business, financial condition, results of operations and cash flows. Additionally, many of our engagements involve projects that are critical to the operations of our customers’ business and provide benefits that are difficult to quantify. Any failure in a customer’s systems or our failure to meet our contractual obligations to our clients, including any breach involving a customer’s confidential information or sensitive data, or our obligations under applicable laws or regulations could result in a claim for substantial damages against us, regardless of our responsibility for such failure. Although we attempt to contractually limit our liability for damages arising from negligent acts, errors, mistakes, or omissions in rendering our services, there can be no assurance that the limitations of liability set forth in our contracts will be enforceable in all instances or will otherwise protect us from liability for damages. Although we have general liability insurance coverage, including coverage for errors or omissions, there can be no assurance that such coverage will cover all types of claims, continue to be available on reasonable terms or will be available in sufficient amounts to cover one or more large claims, or that the insurer will not disclaim coverage as to any future claim. The successful assertion of one or more large claims against us that exceed or are not covered by our insurance coverage or changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a material adverse effect on our business, results of operations, financial condition and cash flows.
	In the normal course of business and in conjunction with certain client engagements, we have entered into contractual arrangements through which we may be obligated to indemnify clients or other parties with whom we conduct business with respect to certain matters. These arrangements can include provisions whereby we agree to hold the indemnified party and certain of their affiliated entities harmless with respect to third-party claims related to such matters as our breach of certain representations or covenants, or out of our intellectual property infringement, our gross negligence or willful misconduct or certain other claims made against certain parties. Payments by us under any of these arrangements are generally conditioned on the client making a claim and providing us with full control over the defense and settlement of such claim. It is not possible to determine the maximum potential amount under these indemnification agreements due to the unique facts and circumstances involved in each particular agreement. Historically, we have not made payments under these indemnification agreements and therefore they have not had any impact on our operating results, financial position, or cash flows. However, if events arise requiring us to make payment for indemnification claims under our indemnification obligations in contracts we have entered, such payments could have material impact on our business, results of operations, financial condition and cash flows.

Segment Reporting [Abstract]
Segment Information	Segment Information
	Our reportable segments are:
	•	Financial Services, which includes customers providing banking/transaction processing, capital markets and insurance services;
	•	Healthcare, which includes healthcare providers and payers as well as life sciences customers, including pharmaceutical, biotech and medical device companies;
	•	Manufacturing/Retail/Logistics, which includes consumer goods, manufacturers, retailers, travel and other hospitality customers, as well as customers providing logistics services; and
	•	Other, which is an aggregation of industry segments each of which, individually, represents less than 10% of consolidated revenues and segment operating profit. The Other reportable segment includes our information, media and entertainment services, communications and high technology operating segments. Our sales managers, account executives, account managers and project teams are aligned in accordance with the specific industries they serve.
	Our chief operating decision maker evaluates the company’s performance and allocates resources based on segment revenues and operating profit. Segment operating profit is defined as income from operations before unallocated costs. Generally, operating expenses for each operating segment have similar characteristics and are subject to the same factors, pressures and challenges. However, the economic environment and its effects on industries served by our operating segments may affect revenue and operating expenses to differing degrees. Expenses included in segment operating profit consist principally of direct selling and delivery costs as well as a per seat charge for use of the development and delivery centers. Certain selling, general and administrative expenses, excess or shortfall of incentive compensation for delivery personnel as compared to target, stock-based compensation expense, a portion of depreciation and amortization and the impact of the settlements of our cash flow hedges are not allocated to individual segments in internal management reports used by the chief operating decision maker. Accordingly, such expenses are excluded from segment operating profit and are separately disclosed as “unallocated” and adjusted only against our total income from operations. Additionally, management has determined that it is not practical to allocate identifiable assets by segment, since such assets are used interchangeably among the segments.
	Revenues from external customers and segment operating profit, before unallocated expenses, for the Financial Services, Healthcare, Manufacturing/Retail/Logistics, and Other reportable segments were as follows:

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recently Adopted Accounting Pronouncements	New Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board, or FASB, issued a standard on revenue from contracts with customers. The new standard sets forth a single comprehensive model for recognizing and reporting revenue. The standard also requires additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. The new standard will be effective for periods beginning on or after January 1, 2017. Early adoption is not permitted. The standard allows for two methods of adoption: the full retrospective adoption, which requires the standard to be applied to each prior period presented, or the modified retrospective adoption, which requires the cumulative effect of adoption to be recognized as an adjustment to opening retained earnings in the period of adoption. We are currently evaluating the effect the new standard will have on our consolidated financial statements and related disclosures.
	In April 2015, the FASB issued a standard related to the presentation of debt issuance costs. The standard requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying value of that debt liability. The recognition and measurement guidance for debt issuance costs are not affected by this standard. The amendment is effective on a retrospective basis for fiscal years, and interim periods within those years, beginning on or after January 1, 2016. The adoption of this standard will affect financial statement presentation only and is expected to have no effect on our financial condition or results of operations.
	In April 2015, the FASB issued a standard providing guidance to customers in evaluating whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the standard requires the customer to account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer is required to account for the arrangement as a service contract. The amendments are effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2016. The Company is currently in the process of evaluating the impact of adoption of the standard on our consolidated financial statements.
