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 six months ended June 30, 2015, we repurchased 2,800,000 shares of our Class A common stock for $177.9 million, inclusive of fees and expenses, under our existing stock repurchase program approved by our Board of Directors. As of June 30, 2015, the remaining available balance under the Board authorization was $636.0 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 six months ended June 30, 2015, such repurchases totaled 565,830 shares at an aggregate cost of $36.1 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. In July 2015, the FASB deferred the effective date of the standard by one year to periods beginning on or after January 1, 2018. Early adoption is permitted but not before the original effective date of periods beginning on or after January 1, 2017. 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.
