Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements of Informatica Corporation (“Informatica,” or the “Company”) have been prepared in conformity with generally accepted accounting principles (“GAAP”) in the United States of America. However, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed, or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, the financial statements include all normal and recurring adjustments that are necessary to fairly present the results of the interim periods presented. All of the amounts included in this Quarterly Report on Form 10-Q related to the condensed consolidated financial statements and notes thereto as of June 30, 2015 and for the three and six months ended June 30, 2015 and 2014 are unaudited. The interim results presented are not necessarily indicative of results for any subsequent interim period, the year ending December 31, 2015 , or any other future period. The preparation of the Company's condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates, judgments, and assumptions. For example, the Company makes estimates, judgments, and assumptions in determining vendor-specific objective evidence ("VSOE") and, estimated selling price ("ESP") used in revenue recognition, the realizability of deferred tax assets, uncertain tax positions, fair value of acquired tangible and intangible assets and liabilities assumed during acquisitions, the number of reporting segments, the recoverability of intangible assets and their useful lives, the fair value of stock options and forfeiture estimates used in calculating stock-based compensations, number of performance-based restricted stock units that the Company expects to vest, and the collectability of accounts receivable. The Company believes that the estimates, judgments, and assumptions upon which it relies are reasonable based on information available at the time that these estimates, judgments, and assumptions are made. These estimates, judgments, and assumptions can affect the reported amounts of assets and liabilities as of the date of the financial statements as well as the reported amounts of revenues and expenses during the periods presented. Any material differences between these estimates and actual results will impact the Company's condensed consolidated financial statements. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require management's judgment in its application. There are also areas in which management's judgment in selecting any available alternative would not produce a materially different result. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated. These unaudited, condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto for the year ended December 31, 2014 included in the Company's Annual Report on Form 10-K, as amended, filed with the SEC. The consolidated balance sheet as of December 31, 2014 has been derived from the audited consolidated financial statements of the Company. The Company's significant accounting policies are described in Note 2 to the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014 . Certain reclassifications have been made within the condensed consolidated statements of cash flows to conform to the current year presentation. A change was made to present redemptions by issuers of debt securities held by the Company as part of net cash provided by maturities of investments to reflect that these redemptions are an acceleration of the maturity of the debt investment. Redemptions were previously presented as part of net cash provided by sales of investments. This change in presentation did not affect total net cash used in investing activities and conforming changes have been made for all prior periods presented. Net cash provided by redemptions of $26.4 million was reclassified from sales of investments to maturities of investments for the six months ended June 30, 2014 . Certain reclassifications have been made within the condensed consolidated statements of income. The Company previously presented $1.4 million of expenses related to the Merger (as defined below) and other stockholder matters as part of general and administrative expenses during the three months ended March 31, 2015 that have been reclassified and presented in acquisitions and other charges in the six months ended June 30, 2015. This change in presentation did not affect total operating expenses during the six months ended June 30, 2015. Merger Agreement On April 6, 2015, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Ithaca Holdco 2 LLC, a Delaware limited liability company (formerly known as Italics Inc., “Newco”) and Ithaca Merger Sub LLC, a Delaware limited liability company formerly known as Italics Merger Sub Inc. and wholly-owned subsidiary of Newco (“Merger Sub”), providing for the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Newco. At the effective time of the Merger, each share of the Company’s common stock issued and outstanding as of immediately prior to the effective time, subject to certain exceptions, will be canceled and extinguished and automatically converted into the right to receive cash in an amount equal to $48.75 , without interest thereon. Generally, all outstanding employee stock options immediately before the effective date of the transaction will be canceled and converted into a right to receive an amount in cash equal to $48.75 per stock option, without interest, less the exercise price. All stock options with an exercise price greater than $48.75 will be canceled without payment. Generally, the performance and market conditions for the performance restricted stock units ("PRSUs") granted during 2015 will be deemed achieved at 100% of the applicable target levels unless the applicable agreements governing the PRSUs specify a greater level of achievement, in which case this greater number of PRSUs will be deemed achieved. All vested RSUs and vested PRSUs (as determined by the Merger Agreement) will be canceled and converted into a right to receive cash in an amount equal to $48.75 per RSU and PRSU, without interest. Generally, the remaining unvested RSUs and PRSUs will be assumed and converted to a right to receive cash equal to $48.75 per award subject to continued employment through an accelerated vesting period. For purposes of the unvested RSUs and PRSUs, each vest date underlying the applicable awards will be accelerated by 12 months . See Note 8. Stock-Based Compensation of Notes to Condensed Consolidated Financial Statements in Part I, Item 1 of this Report. Newco and Merger Sub have secured committed financing, consisting of a combination of equity to be provided by the Canada Pension Plan Investment Board (“CPPIB”) and investment funds (the “Permira Funds”) advised by Permira Advisers LLC and debt financing from Bank of America, Goldman Sachs Bank, Credit Suisse Securities, Macquarie Capital, Morgan Stanley Senior Funding, Nomura Securities International, RBC Capital Markets and Deutsche Bank Securities, the aggregate proceeds of which, together with the Company’s available cash, cash equivalents or marketable securities will be sufficient for Newco and Merger Sub to pay the aggregate merger consideration and all related fees and expenses. The Merger is not subject to a financing condition. Consummation of the Merger is subject to customary closing conditions, including, without limitation, the absence of certain legal impediments, the expiration or termination of the required waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended ("HSR Act"), antitrust regulatory approval in the European Union, Turkey, Russia and Israel, and the receipt of written notice from the Committee on Foreign Investment in the United States ("CFIUS") that it has concluded its review of the joint voluntary notice that will be made by the parties to the Merger Agreement pursuant to Section 721 of the Defense Production Act, as amended, with a determination that there are no unresolved national security concerns with respect to the transaction contemplated by the Merger Agreement, and approval by the Company's stockholders. The Company has received antitrust regulatory approval (or the required waiting periods have expired or terminated) in the European Union, Turkey, Russia, Israel, and under the HSR Act. In addition, the Company has received the required written notice from CFIUS. Furthermore, on June 23, 2015, the Company held a special meeting of stockholders, who voted on and approved the Merger. The Company has made customary representations and warranties in the Merger Agreement and have agreed to customary covenants regarding the operation of the Company’s business prior to the effective time of the Merger. The Company is also subject to customary restrictions on its ability to solicit alternative acquisition proposals from third parties and to provide non-public information to, and participate in discussions and engage in negotiations with, third parties regarding alternative acquisition proposals, with customary exceptions for a Superior Proposal (as such term is defined in the Merger Agreement). The Merger Agreement contains certain termination rights for the Company and Newco. Under specified circumstances, the Company will be required to pay Newco a termination fee of $160 million . This fee will become payable by the Company, in each case subject to the terms and conditions of the Merger Agreement, if before receiving stockholder approval of the Merger the Company terminates the Merger Agreement in connection with a competing acquisition transaction or Newco terminates the Merger Agreement in connection with a breach of covenant by the Company that would cause a failure of our closing conditions to be satisfied, in each case a competing acquisition transaction has been publicly announced, and within one year of termination the Company completes a competing acquisition transaction, or enters into an agreement for a competing acquisition transaction that is subsequently consummated, the Company terminates the Merger Agreement to take a Superior Proposal, or Newco terminates the Merger Agreement in connection with the Company’s board of directors failing to make, or withdrawing, its recommendation of the Merger. Under other specified circumstances, Newco will be required to pay the Company a termination fee of $320 million . This fee will become payable by Newco, in each case subject to the terms and conditions of the Merger Agreement, if the Company terminates the Merger Agreement, provided that Newco is not permitted to terminate the Merger Agreement at such time, in connection with a breach by Newco that would cause a failure of Newco’s closing conditions to be satisfied, or if the Company terminates the Merger Agreement in connection with the Termination Date (as defined below), and at the time of termination we would have been entitled to terminate due to Newco’s breach such that Newco’s closing conditions would not be satisfied or due to Newco’s failure to close the Merger notwithstanding the satisfaction of our closing conditions and Newco’s obligation to close. CPPIB and the Permira Funds have provided the Company with a fee funding agreement in favor of Informatica (the “Fee Funding Agreement”). In the aggregate, the Fee Funding Agreement guarantees the payment of the termination fee payable by Newco, any interest that may be due thereon and certain reimbursement obligations that may be owed by Newco to the Company pursuant to the Merger Agreement. The Merger Agreement also provides that either party may specifically enforce the other party’s obligations under the Merger Agreement, provided that the Company may only cause Newco to fund the equity financing if certain conditions are satisfied, including the funding or availability of the debt financing at closing. In addition to the foregoing termination rights, and subject to certain limitations, the Company or Newco may terminate the Merger Agreement if the Merger is not consummated on or before the first business day after October 6, 2015 (the “Termination Date”). The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of such agreement attached as an exhibit to the Current Report on Form 8-K filed with the SEC on April 7, 2015. Recent Accounting Pronouncements In April 2015, the FASB issued Accounting Standards Update ("ASU") 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, as part of its simplification initiative and clarifies how customers in cloud computing arrangements should determine whether the arrangement includes a software license. Existing GAAP does not include explicit guidance about a customer's accounting for fees paid in a cloud computing arrangement. This ASU eliminates the current requirement that customers analogize to the leases standard when determining the assets acquired in a software license arrangement. If a cloud computing arrangement includes a software license, then the customer should account for the software licenses 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 should account for the arrangement as a service contract. As a result of this ASU, all software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. The ASU is effective for us beginning in 2016, with early adoption permitted. An entity can elect to adopt the ASU either (1) prospectively to all arrangements entered into or materially modified after the effective date; or (2) retrospectively. For prospective transition, the only disclosure requirements at transition are the nature of and reason for the change in accounting principle, the transition method, and a qualitative description of the description of the financial statement line items affected by the change. For retrospective transition, the disclosure requirements at transition include the requirements for prospective transition and quantitative information about the effects of the accounting change. The Company is currently assessing its pending adoption of ASU 2015-05 on its consolidated financial statements and disclosures. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest (Subtopic 835-30), Simplifying the Presentation of Debt Issuance Costs, that requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct reduction from the debt liability, consistent with debt discounts, rather than as an asset. The recognition and measurement guidance for debt issuance costs is not affected by the amendments in this update. This ASU is part of the FASB's initiative to reduce complexity in accounting standards and is effective for the Company beginning in 2016 and early adoption is permitted. The standard requires full retrospective adoption, meaning the standard is applied to all periods presented. The Company is currently assessing its pending adoption of ASU 2015-03 on its consolidated financial statements and disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those good and services. T he FASB decided to delay the effective date of this ASU for reporting periods beginning after December 15, 2017, with early adoption permitted as of the original effective date. As a result, the proposed new effective date for calendar year public companies will be January 1, 2018. ASU 2014-09 allows for two methods of adoption: (a) "full retrospective" adoption, meaning the standard is applied to all periods presented, or (b) "modified retrospective" adoption, meaning the cumulative effect of applying ASU 2014-09 is recognized as an adjustment to the 2017 opening retained earnings balance. The Company has not yet selected a transition method and is currently evaluating the impact of its pending adoption of ASU 2014-09 on its consolidated financial statements and disclosures. In June 2014, the FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period . ASU 2014-12 requires that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 is effective for the Company in its first quarter of 2016 with early adoption permitted. The Company does not expect its pending adoption of ASU 2014-12 to have a material impact on its consolidated financial statements and disclosures. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for the Company in the first quarter of 2017 with early adoption permitted. The Company does not expect its pending adoption of ASU 2014-15 to have an impact on the consolidated financial statements and disclosures. There have been no other changes to the Company's significant accounting policies since the end of 2014 .

(iv) Included in accrued liabilities on the condensed consolidated balance sheets. (v) Included in accrued liabilities and other liabilities on the consolidated balance sheets. Money Market Funds, Time Deposits, and Marketable Debt Securities The Company uses a market approach for determining the fair value of all its Level 1 and Level 2 money market funds, time deposits, and marketable securities. The Company's marketable securities consist of municipal securities. To value its money market funds and time deposits, the Company values the funds at $1 stable net asset value, which is the market pricing convention for identical assets that the Company has the ability to access. To value its certificates of deposit and commercial paper, the Company uses mathematical calculations to arrive at fair value for these securities, which generally have short maturities and infrequent secondary market trades. For example, in the absence of any observable transactions, the Company may accrete from purchase price at purchase date to face value at maturity. In the event that a transaction is observed on the same security in the marketplace, and the price on that subsequent transaction clearly reflects the market price on that day, the Company will adjust the price in the system to the observed transaction price and follow a revised accretion schedule to determine the daily price. To determine the fair value of its municipal securities, the Company uses a third party pricing source for each security. If the market price is not available from the third party source, pricing from the Company's investment custodian is used. Foreign Currency Derivatives and Hedging Instruments The Company uses the income approach to value the derivatives using observable Level 2 market inputs at the measurement date and standard valuation techniques to convert future amounts to a single present value amount, assuming that participants are motivated but not compelled to transact. Level 2 inputs are limited to quoted prices that are observable for the derivative assets and liabilities. The Company records its derivative assets and liabilities at gross in the condensed consolidated balance sheet and uses mid-market pricing as a practical expedient for fair value measurements. Key inputs for foreign currency derivatives are the spot rates, forward rates, interest rates, and credit derivative market rates. The spot rate for each foreign currency is the same spot rate used for all balance sheet translations at the measurement date and is sourced from the Federal Reserve Bulletin. The following values are interpolated from commonly quoted intervals available from Bloomberg: forward points and the London Interbank Offered Rate (“LIBOR”) used to discount and determine the fair value of assets and liabilities. Credit default swap spread curves identified per counterparty at month end in Bloomberg are used to discount derivative assets for counterparty non-performance risk, all of which have terms of nine months or less. The Company discounts derivative liabilities to reflect the Company’s own potential non-performance risk to lenders and has used the spread over LIBOR on its most recent corporate borrowing rate. The counterparties associated with the Company’s foreign currency forward contracts are large credit-worthy financial institutions, and the derivatives transacted with these entities are relatively short in duration; therefore, the Company does not consider counterparty concentration and non-performance to be material risks at this time. Both the Company and the counterparties are expected to perform under the contractual terms of the instruments. There were no transfers between Level 1, Level 2 and Level 3 categories during the three and six months ended June 30, 2015 and 2014 . See Note 5.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company’s earnings and cash flows are subject to fluctuations due to changes in foreign currency exchange rates. The Company uses derivative instruments to manage its exposures to fluctuations in certain foreign currency exchange rates which exist as part of ongoing business operations. The Company and its subsidiaries do not enter into derivative contracts for speculative purposes. Cash Flow Hedges The Company enters into certain cash flow hedge programs in an attempt to reduce the impact of certain foreign currency fluctuations. These contracts are designated and documented as cash flow hedges. The purpose of these programs is to reduce the volatility of identified cash flow and expenses caused by movement in certain foreign currency exchange rates, in particular, the Indian rupee. The Company is currently using foreign exchange forward contracts to hedge the foreign currency anticipated expenses of its subsidiary in India. The Company releases the amounts accumulated in other comprehensive income into earnings in the same period or periods during which the forecasted hedge transaction affects earnings. The Company will reclassify all amounts accumulated in other comprehensive income into earnings within the next 12 months . The Company has forecasted the amount of its anticipated foreign currency expenses based on its historical performance and its projected financial plan. As of June 30, 2015 , the remaining open foreign exchange contracts, carried at fair value, are hedging Indian rupee expenses and have a maturity of nine months or less. These foreign exchange contracts mature monthly as the foreign currency denominated expenses are paid and any gain or loss is offset against operating expense. Once the hedged item is recognized, the cash flow hedge is de-designated and subsequent changes in value are recognized in other income (expense) to offset changes in the value of the resulting non-functional currency monetary assets or liabilities. The notional amounts of these foreign exchange forward contracts in U.S. dollar equivalents were to buy $26.1 million and $45.9 million of Indian rupees as of June 30, 2015 and December 31, 2014 , respectively. Balance Sheet Hedges Balance Sheet hedges consist of cash flow hedge contracts that have been de-designated and non-designated balance sheet hedges. These foreign exchange contracts are carried at fair value and either did not or no longer qualify for hedge accounting treatment and are not designated as hedging instruments. Changes in the value of the foreign exchange contracts are recognized in other income (expense) and offset the foreign currency gain or loss on the underlying net monetary assets or liabilities. The notional amounts of foreign currency contracts open at period end in US dollar equivalents were to buy $16.0 million and $10.6 million of Indian rupees at June 30, 2015 and December 31, 2014 , respectively. The notional amounts of foreign currency contracts open at period end in U.S. dollar equivalents were to sell $3.7 million of Indian rupees and $57.1 million of Euros at June 30, 2015 and December 31, 2014 , respectively. The following table reflects the fair value amounts for the foreign exchange contracts designated and not designated as hedging instruments at June 30, 2015 and December 31, 2014 (in thousands): June 30, 2015 December 31, 2014 Fair Value Derivative Assets (i) Fair Value Derivative Liabilities (ii) Fair Value Derivative Assets (i) Fair Value Derivative Liabilities (iii) Derivatives designated as hedging instruments $ 116 $ 74 $ 141 $ 761 Derivatives not designated as hedging instruments 83 118 169 154 Total fair value of derivative instruments $ 199 $ 192 $ 310 $ 915 ____________________ (i) Included in prepaid expenses and other current assets on the condensed consolidated balance sheets.

However, under the master netting agreements with the respective counterparties of the foreign exchange contracts, subject to applicable requirements, the Company is allowed to net settle transactions of the same currency with a single net amount payable by one party to the other. The derivatives held by the Company are not subject to any credit contingent features negotiated with its counterparties. The Company is not required to pledge nor is entitled to receive cash collateral related to the above contracts.

Stock Repurchase Program [Abstract]
Stock Repurchase Program	Stock Repurchase Program The Company's Board of Directors has approved a stock repurchase program for the Company to repurchase its common stock. The primary purpose of the program is to enhance shareholder value, including partially offsetting the dilutive impact of stock-based incentive plans. The number of shares to be purchased and the timing of the purchases are based on several factors, including the price of the Company's common stock, the Company's liquidity and working capital needs, general business and market conditions, and other investment opportunities. These purchases can be made from time to time in the open market and are funded from the Company’s available working capital. In each of January, July, and October of 2014, the Board of Directors approved the repurchase of up to an additional $100 million of the Company's outstanding common stock, with such authorizations aggregating to $300 million . In January 2015, we announced that the Board of Directors approved an additional $337 million to augment its existing authorization under our stock repurchase program. Subsequently in February 2015, we entered into separate accelerated stock repurchase ("ASR") agreements with two financial institutions to repurchase an aggregate of $300 million of our common stock. Under the terms of the ASR agreements, we paid an aggregate of $300 million in cash and received an initial delivery of approximately 5,725,000 shares on February 4, 2015. In June 2015, the ASR agreements were settled and the Company received an additional 773,000 shares, which were retired. In total, 6,498,000 shares were delivered under the ASR agreements at an average repurchase price of $46.17 per share. The repurchase program authorized by the Board of Directors does not have an expiration date. Repurchased shares are retired and reclassified as authorized and unissued shares of common stock. As of June 30, 2015, $200 million of the previous authorizations remained available for future repurchases. During the three and six months ended June 30, 2014 , the Company repurchased approximately 896,000 shares of its common stock at a cost of $32.5 million and approximately 1,478,000 shares of its common stock at a cost of $55.9 million , respectively.

Stock-Based Compensation

Stock-Based Compensation	6 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company grants stock options, restricted stock units (“RSUs”) and performance-based restricted stock units (“PRSUs”) under its 2009 Equity Incentive Plan. Eligible employees may elect to purchase shares of common stock through the Employee Stock Purchase Plan ("ESPP"). The fair value of each option award and ESPP share is estimated on the date of grant using the Black-Scholes-Merton option pricing model that uses the assumptions in the following table. The Company has consistently used a blend of average historical and market-based implied volatilities for calculating the expected volatilities for employee stock options, and uses market-based implied volatilities for its ESPP. The expected term of employee stock options granted is derived from historical exercise patterns of the options, and the expected term of ESPP is based on the contractual terms. The expected term of options granted to employees is derived from the historical option exercises, post-vesting cancellations, and estimates concerning future exercises and cancellations for vested and unvested options that remain outstanding. The risk-free interest rate for the expected term of the option and ESPP is based on the U.S. Treasury yield curve in effect at the time of grant. The Company recognizes its stock-based compensation related to options using a straight-line method over the vesting term of the awards. The Company recognizes its stock-based compensation related to ESPP using a straight-line method over the offering period, which is six months. The fair value of RSUs is the grant date closing price of our common stock. In the first quarter of 2015, the Company granted two types of PRSUs. The fair value of PRSUs, with service and performance conditions, is the grant date closing price of our common stock. The grant date fair value of the PRSUs requiring the satisfaction of service, performance, and market conditions was determined by using a Monte Carlo simulation model, which utilized multiple input variables that determined the probability of satisfying the market condition requirements. The Company recognizes expense related to RSUs using a straight-line method over the vesting term of the awards. The Company recognizes expense for PRSUs, with service and performance conditions, based on the probability of achieving the performance criteria, as defined in the PRSU agreements. The Company recognizes expense for PRSUs with service, performance, and market conditions based on the probability of achieving the performance conditions as long as the requisite service is rendered, even if the market conditions are not met. PRSUs are expensed using the graded vesting attribution method over the requisite service period. The Company records stock-based compensation for options, RSUs and PRSUs granted net of estimated forfeiture rates. The Company estimates forfeiture rates at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical forfeitures to estimate its future forfeiture rates. The fair value of the Company’s stock-based awards was estimated based on the following assumptions: Three Months Ended Six Months Ended 2015 2014 2015 2014 Option grants: Expected volatility 21 % 37 % 21% -31% 37 - 40% Expected dividends — — — — Expected term of options (in years) 3.5 3.5 3.5 3.5 Risk-free interest rate 1.2 % 1.3 % 1.1 % 1.1 % ESPP: (i) Expected volatility — % — % 29 % 36 % Expected dividends — — — — Expected term of ESPP (in years) — — 0.5 0.5 Risk-free interest rate — % — % 0.1 % 0.1 % PRSUs with market conditions: Expected volatility — % — % 30% - 39% — % Expected dividends — — — — Risk-free interest rate — % — % 1.0 % — % ____________________ (i) ESPP purchases are scheduled for the last day of January and July of each year.

If certain performance goals are met, PRSUs would become eligible to vest, and vest ratably over four years on the annual anniversary dates of the vesting commencement date, contingent upon the recipient’s continued service to the company. Certain participants have the ability to receive up to 125% of the target number of shares originally granted. The Compensation Committee of the Board of Directors will certify actual performance achievement for these PRSUs in the first quarter of 2016. The weighted-average grant date fair value of these PRSUs was $43.06 per share. • Approximately 88,000 of these PRSUs have a performance period that is the three year period beginning with January 1, 2015 through December 31, 2017 with certain revenue based performance goals and the achievement of an objective relative total stockholder return against other companies in the S&P Software & Services Select Index measured over a three-year performance period. Participants have the ability to receive up to 188% of the target number of shares originally granted. The Compensation Committee of the Board of Directors will certify actual performance achievement for these PRSUs in the first quarter of 2018, after which they will vest immediately in full. The weighted-average grant date fair value of 2015 PRSUs was $46.93 per share, which was determined using a Monte Carlo simulation model. During the first quarter of 2014, the Company granted approximately 223,000 target PRSUs. The performance period for the PRSUs granted in 2014 was the 2014 fiscal year. In the first quarter of 2015, the Compensation Committee of the Board of Directors certified actual performance achievement for PRSUs granted in 2014, and as a result, 138,000 shares became eligible to vest. The achieved PRSUs vest ratably over two or four years on the annual anniversary dates of the grant, contingent upon the recipient’s continued service to the Company. Certain participants had the ability to receive up to 125% to 150% of the target number of shares originally granted. The weighted-average grant date fair value of PRSUs granted in 2014 was $38.25 per share.

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rates were 42% and 34% for the three months ended June 30, 2015 and 2014 , respectively, and 39% and 34% for the six months ended June 30, 2015 and 2014 , respectively. The rates for the three and six months ended June 30, 2015 were higher than the federal statutory rate of 35% mainly due to a change in management assertion with respect to our foreign undistributed earnings. The rates for the three and six months ended June 30, 2014 were similar to the federal statutory rate of 35% as the benefits of foreign earnings in lower-tax jurisdictions and the domestic manufacturing deduction were offset by nondeductible stock-based compensation, state income taxes, and the accrual of reserves related to unrecognized tax benefits. The tax rates for three and six months ended June 30, 2015 and 2014 do not include the federal research and development tax credit benefit as the credit was not reinstated for the respective interim periods. As of December 31, 2014 , the Company had approximately $128.2 million of undistributed earnings from its foreign subsidiaries for which the Company had not provided U.S. income or applicable foreign withholding taxes. During the three months ended June 30, 2015 , the Company changed its assertion for undistributed foreign earnings and expects to use its available cash that the Company holds in foreign jurisdictions as part of the acquisition consideration for the pending Merger. Consequently, the Company provided for U.S. income taxes (after the consideration of foreign tax credit) and applicable foreign withholding taxes on all foreign undistributed earnings as these earnings will be repatriated to the U.S. The repatriation is expected to generate a total of $5.6 million of additional U.S. income tax expense in 2015. This includes $7.4 million of U.S. income tax expense for the current year earnings generated by foreign subsidiaries and $1.8 million of net discrete tax benefit recorded for prior year cumulative undistributed earnings in the three months ended June 30, 2015 . The current and prior year income tax benefit from corresponding foreign tax credits are included in the computation of the U.S. income tax expenses provided on undistributed foreign earnings because the Company believes it is more-likely-than-not that it will realize the benefit from these foreign tax credits before they expire. ASC 740, Income Taxes , provides for the recognition of deferred tax assets if realization of such assets is more likely than not. In assessing the need for any additional valuation allowance for the three months ended June 30, 2015 , the Company considered all available evidence both positive and negative, including historical levels of income, legislative developments, expectations and risks associated with estimates of future taxable income, and ongoing prudent and feasible tax planning strategies. As a result of this analysis for the three months ended June 30, 2015 , consistent with prior periods, it was considered more likely than not that the Company's deferred tax assets would be realized except for any increase to the deferred tax assets related to the California research and development credit and certain operating losses incurred outside of the United States. A valuation allowance has been recorded against this portion of the state tax credit, even though this attribute has an indefinite life. In addition, the Company recorded a valuation allowance related to the deferred tax assets attributable to certain operating losses incurred outside of the United States. The unrecognized tax benefits related to ASC 740, if recognized, would impact the income tax provision by $28.2 million and $26.6 million as of June 30, 2015 and 2014 , respectively. The Company has elected to include interest and penalties as a component of income tax expenses. Accrued interest and penalties as of June 30, 2015 and 2014 were approximately $2.7 million and $3.7 million , respectively. As of June 30, 2015 , the gross unrecognized tax benefit was approximately $34.3 million . The Company files U.S. federal income tax returns as well as income tax returns in various states and foreign jurisdictions. The Company has been informed by certain state and foreign taxing authorities that it was selected for examination. Most state and foreign jurisdictions have three to six open tax years at any point in time. The field work for certain state and foreign audits have commenced and are at various stages of completion as of June 30, 2015 . Although the outcome of any tax audit is uncertain, the Company believes that it has adequately provided in its financial statements for any additional taxes that it may be required to pay as a result of these examinations. The Company regularly assesses the likelihood of outcomes resulting from these examinations to determine the adequacy of its provision for income taxes and believes its current reserve to be reasonable. If tax payments ultimately prove to be unnecessary, the reversal of these tax liabilities would result in tax benefits in the period that the Company had determined such liabilities were no longer necessary. However, if an ultimate tax assessment exceeds its estimate of tax liabilities, an additional tax provision might be required.

Commitments and Contingencies

Commitments and Contingencies	6 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Lease Obligations The Company leases certain office facilities under various non-cancelable operating leases, which expire at various dates through 2024 and require the Company to pay operating costs, including property taxes, insurance, and maintenance. Future minimum lease payments as of June 30, 2015 under non-cancelable operating leases with original terms in excess of one year are summarized as follows (in thousands): Operating Leases Remaining 2015 $ 6,212 2016 10,420 2017 8,946 2018 7,774 2019 6,324 Thereafter 8,126 Total future minimum operating lease payments $ 47,802 Warranties The Company generally provides a warranty for its software products and services to its customers for a period of three to six months. The Company’s software products’ media are generally warranted to be free from defects in materials and workmanship under normal use, and the products are also generally warranted to substantially perform as described in certain Company documentation and the product specifications. The Company’s services are generally warranted to be performed in a professional manner and to materially conform to the specifications set forth in a customer’s signed contract. In the event there is a failure of such warranties, the Company generally will correct or provide a reasonable work-around or replacement product. To date, the Company’s product warranty expense has not been significant. The warranty accrual as of June 30, 2015 and December 31, 2014 was not material. Indemnification The Company's software license agreements generally include certain provisions for indemnifying the customer against losses, expenses, liabilities, and damages that may be awarded against the customer in the event the Company’s software is found to infringe upon a patent, copyright, trademark, or other proprietary right of a third party. The agreements generally limit the scope of and remedies for such indemnification obligations in a variety of industry-standard respects, including but not limited to certain time and scope limitations and a right to replace an infringing product with a non-infringing product. The Company believes its internal development processes and other policies and practices limit its exposure related to these indemnification provisions. In addition, the Company requires its employees to sign a proprietary information and inventions agreement, which assigns the rights to its employees’ development work to the Company. To date, the Company has not had to reimburse any of its customers for any losses related to these indemnification provisions, and no material claims against the Company are outstanding as of June 30, 2015 . The Company cannot determine the maximum amount of potential future payments, if any, related to such indemnification provisions due to the limited and infrequent history of prior indemnification claims. As permitted under Delaware law, the Company has agreements whereby the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was serving, at our request, in such capacity. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has director and officer insurance coverage that reduces the Company's exposure and enables the Company to recover a portion of any future amounts paid. The Company believes the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal. The Company accrues for loss contingencies when available information indicates that it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated in accordance with ASC 450, Contingencies . Derivative Financial Instruments The Company uses derivative instruments to manage its exposure to fluctuations in certain foreign currency exchange rates which exist as part of ongoing business operations. See Note 1. Summary of Significant Accounting Policies , Note 5. Accumulated Other Comprehensive Income (Loss) , and Note 6. Derivative Financial Instruments of Notes to Condensed Consolidated Financial Statements in Part I, Item 1 of this Report for a further discussion. Litigation The Company is a party to various legal proceedings and claims arising from the normal course of its business activities, including proceedings and claims related to patents and other intellectual property related matters. On April 16, 2015, two stockholder class action complaints were filed in the Court of Chancery of the State of Delaware on behalf of a putative class of the Company’s stockholders: Luciano Scotto v. Sohaib Abbasi et al. , Case No. 10913 (filed April 16, 2015) and Janice Ridgeway v. Informatica Corporation et al. , Case No. 10917 (filed April 16, 2015). The two complaints were then consolidated by court order on May 5, 2015 and re-captioned as In re Informatica Corporation Shareholder Litigation, Consolidated C.A. No. 10913-VCL (the “Consolidated Complaint”). On May 13, 2015, a third complaint, Janet Daniels v. Informatica Corp., et al. , Case No. 11016, was filed in the Court of Chancery of the State of Delaware (the “Daniels Complaint”) The complaints generally allege that, in connection with the acquisition of the Company by Newco, the Informatica directors breached their fiduciary duties owed to the Company’s stockholders by agreeing to sell the company for purportedly inadequate consideration, engaging in a flawed sales process, and agreeing to a number of purportedly preclusive deal protection devices. The complaints further allege that Newco, Merger Sub, the Permira Funds, CPPIB, and the Company aided and abetted the Board of Directors in the alleged breaches of fiduciary duties. The Consolidated Complaint and the Daniels Complaint also allege that the Informatica directors breached their fiduciary duties by omitting material information necessary for stockholders to make an informed vote. The complaints seek, among other things, an order enjoining the close of the transaction or, in the event that the transaction is consummated, an award of rescission and/or rescissory damages. The Company reviews the status of each matter and records a provision for a liability when it is considered both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed quarterly and adjusted as additional information becomes available. If both of the criteria are not met, the Company assesses whether there is at least a reasonable possibility that a loss, or additional losses, may be incurred. If there is a reasonable possibility that a material loss may be incurred, the Company discloses the estimate of the possible loss, range of loss, or a statement that such an estimate cannot be made. Litigation is subject to inherent uncertainties. Were an unfavorable outcome to occur, there exists the possibility of a material adverse impact on the Company's financial position and results of operation for the period in which the unfavorable outcome occurred, and potentially in future periods.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements of Informatica Corporation (“Informatica,” or the “Company”) have been prepared in conformity with generally accepted accounting principles (“GAAP”) in the United States of America. However, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed, or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, the financial statements include all normal and recurring adjustments that are necessary to fairly present the results of the interim periods presented. All of the amounts included in this Quarterly Report on Form 10-Q related to the condensed consolidated financial statements and notes thereto as of June 30, 2015 and for the three and six months ended June 30, 2015 and 2014 are unaudited. The interim results presented are not necessarily indicative of results for any subsequent interim period, the year ending December 31, 2015 , or any other future period. The preparation of the Company's condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates, judgments, and assumptions. For example, the Company makes estimates, judgments, and assumptions in determining vendor-specific objective evidence ("VSOE") and, estimated selling price ("ESP") used in revenue recognition, the realizability of deferred tax assets, uncertain tax positions, fair value of acquired tangible and intangible assets and liabilities assumed during acquisitions, the number of reporting segments, the recoverability of intangible assets and their useful lives, the fair value of stock options and forfeiture estimates used in calculating stock-based compensations, number of performance-based restricted stock units that the Company expects to vest, and the collectability of accounts receivable. The Company believes that the estimates, judgments, and assumptions upon which it relies are reasonable based on information available at the time that these estimates, judgments, and assumptions are made. These estimates, judgments, and assumptions can affect the reported amounts of assets and liabilities as of the date of the financial statements as well as the reported amounts of revenues and expenses during the periods presented. Any material differences between these estimates and actual results will impact the Company's condensed consolidated financial statements. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require management's judgment in its application. There are also areas in which management's judgment in selecting any available alternative would not produce a materially different result. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated. These unaudited, condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto for the year ended December 31, 2014 included in the Company's Annual Report on Form 10-K, as amended, filed with the SEC. The consolidated balance sheet as of December 31, 2014 has been derived from the audited consolidated financial statements of the Company. The Company's significant accounting policies are described in Note 2 to the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014 .
Reclassifications to Conform to Current Year Presentation	Certain reclassifications have been made within the condensed consolidated statements of cash flows to conform to the current year presentation. A change was made to present redemptions by issuers of debt securities held by the Company as part of net cash provided by maturities of investments to reflect that these redemptions are an acceleration of the maturity of the debt investment. Redemptions were previously presented as part of net cash provided by sales of investments. This change in presentation did not affect total net cash used in investing activities and conforming changes have been made for all prior periods presented. Net cash provided by redemptions of $26.4 million was reclassified from sales of investments to maturities of investments for the six months ended June 30, 2014 . Certain reclassifications have been made within the condensed consolidated statements of income. The Company previously presented $1.4 million of expenses related to the Merger (as defined below) and other stockholder matters as part of general and administrative expenses during the three months ended March 31, 2015 that have been reclassified and presented in acquisitions and other charges in the six months ended June 30, 2015. This change in presentation did not affect total operating expenses during the six months ended June 30, 2015.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2015, the FASB issued Accounting Standards Update ("ASU") 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, as part of its simplification initiative and clarifies how customers in cloud computing arrangements should determine whether the arrangement includes a software license. Existing GAAP does not include explicit guidance about a customer's accounting for fees paid in a cloud computing arrangement. This ASU eliminates the current requirement that customers analogize to the leases standard when determining the assets acquired in a software license arrangement. If a cloud computing arrangement includes a software license, then the customer should account for the software licenses 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 should account for the arrangement as a service contract. As a result of this ASU, all software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. The ASU is effective for us beginning in 2016, with early adoption permitted. An entity can elect to adopt the ASU either (1) prospectively to all arrangements entered into or materially modified after the effective date; or (2) retrospectively. For prospective transition, the only disclosure requirements at transition are the nature of and reason for the change in accounting principle, the transition method, and a qualitative description of the description of the financial statement line items affected by the change. For retrospective transition, the disclosure requirements at transition include the requirements for prospective transition and quantitative information about the effects of the accounting change. The Company is currently assessing its pending adoption of ASU 2015-05 on its consolidated financial statements and disclosures. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest (Subtopic 835-30), Simplifying the Presentation of Debt Issuance Costs, that requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct reduction from the debt liability, consistent with debt discounts, rather than as an asset. The recognition and measurement guidance for debt issuance costs is not affected by the amendments in this update. This ASU is part of the FASB's initiative to reduce complexity in accounting standards and is effective for the Company beginning in 2016 and early adoption is permitted. The standard requires full retrospective adoption, meaning the standard is applied to all periods presented. The Company is currently assessing its pending adoption of ASU 2015-03 on its consolidated financial statements and disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those good and services. T he FASB decided to delay the effective date of this ASU for reporting periods beginning after December 15, 2017, with early adoption permitted as of the original effective date. As a result, the proposed new effective date for calendar year public companies will be January 1, 2018. ASU 2014-09 allows for two methods of adoption: (a) "full retrospective" adoption, meaning the standard is applied to all periods presented, or (b) "modified retrospective" adoption, meaning the cumulative effect of applying ASU 2014-09 is recognized as an adjustment to the 2017 opening retained earnings balance. The Company has not yet selected a transition method and is currently evaluating the impact of its pending adoption of ASU 2014-09 on its consolidated financial statements and disclosures. In June 2014, the FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period . ASU 2014-12 requires that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 is effective for the Company in its first quarter of 2016 with early adoption permitted. The Company does not expect its pending adoption of ASU 2014-12 to have a material impact on its consolidated financial statements and disclosures. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for the Company in the first quarter of 2017 with early adoption permitted. The Company does not expect its pending adoption of ASU 2014-15 to have an impact on the consolidated financial statements and disclosures.
Fair Value Measurement of Financial Assets and Liabilities	Money Market Funds, Time Deposits, and Marketable Debt Securities The Company uses a market approach for determining the fair value of all its Level 1 and Level 2 money market funds, time deposits, and marketable securities. The Company's marketable securities consist of municipal securities. To value its money market funds and time deposits, the Company values the funds at $1 stable net asset value, which is the market pricing convention for identical assets that the Company has the ability to access. To value its certificates of deposit and commercial paper, the Company uses mathematical calculations to arrive at fair value for these securities, which generally have short maturities and infrequent secondary market trades. For example, in the absence of any observable transactions, the Company may accrete from purchase price at purchase date to face value at maturity. In the event that a transaction is observed on the same security in the marketplace, and the price on that subsequent transaction clearly reflects the market price on that day, the Company will adjust the price in the system to the observed transaction price and follow a revised accretion schedule to determine the daily price. To determine the fair value of its municipal securities, the Company uses a third party pricing source for each security. If the market price is not available from the third party source, pricing from the Company's investment custodian is used. Foreign Currency Derivatives and Hedging Instruments The Company uses the income approach to value the derivatives using observable Level 2 market inputs at the measurement date and standard valuation techniques to convert future amounts to a single present value amount, assuming that participants are motivated but not compelled to transact. Level 2 inputs are limited to quoted prices that are observable for the derivative assets and liabilities. The Company records its derivative assets and liabilities at gross in the condensed consolidated balance sheet and uses mid-market pricing as a practical expedient for fair value measurements. Key inputs for foreign currency derivatives are the spot rates, forward rates, interest rates, and credit derivative market rates. The spot rate for each foreign currency is the same spot rate used for all balance sheet translations at the measurement date and is sourced from the Federal Reserve Bulletin. The following values are interpolated from commonly quoted intervals available from Bloomberg: forward points and the London Interbank Offered Rate (“LIBOR”) used to discount and determine the fair value of assets and liabilities. Credit default swap spread curves identified per counterparty at month end in Bloomberg are used to discount derivative assets for counterparty non-performance risk, all of which have terms of nine months or less. The Company discounts derivative liabilities to reflect the Company’s own potential non-performance risk to lenders and has used the spread over LIBOR on its most recent corporate borrowing rate. The counterparties associated with the Company’s foreign currency forward contracts are large credit-worthy financial institutions, and the derivatives transacted with these entities are relatively short in duration; therefore, the Company does not consider counterparty concentration and non-performance to be material risks at this time. Both the Company and the counterparties are expected to perform under the contractual terms of the instruments.
Marketable Securities	The cost of securities sold was determined based on the specific identification method.
Derivatives, Offsetting Fair Value Amounts, Policy	The Company presents its derivative assets and derivative liabilities at gross fair values in the condensed consolidated balance sheets. However, under the master netting agreements with the respective counterparties of the foreign exchange contracts, subject to applicable requirements, the Company is allowed to net settle transactions of the same currency with a single net amount payable by one party to the other. The derivatives held by the Company are not subject to any credit contingent features negotiated with its counterparties. The Company is not required to pledge nor is entitled to receive cash collateral related to the above contracts.
Derivatives, Methods of Accounting, Hedge Effectiveness	The Company evaluates prospectively as well as retrospectively the effectiveness of its hedge programs using statistical analysis. Prospective testing is performed at the inception of the hedge relationship and quarterly thereafter. Retrospective testing is performed on a quarterly basis.
Stock-Based Compensation	The Company grants stock options, restricted stock units (“RSUs”) and performance-based restricted stock units (“PRSUs”) under its 2009 Equity Incentive Plan. Eligible employees may elect to purchase shares of common stock through the Employee Stock Purchase Plan ("ESPP"). The fair value of each option award and ESPP share is estimated on the date of grant using the Black-Scholes-Merton option pricing model that uses the assumptions in the following table. The Company has consistently used a blend of average historical and market-based implied volatilities for calculating the expected volatilities for employee stock options, and uses market-based implied volatilities for its ESPP. The expected term of employee stock options granted is derived from historical exercise patterns of the options, and the expected term of ESPP is based on the contractual terms. The expected term of options granted to employees is derived from the historical option exercises, post-vesting cancellations, and estimates concerning future exercises and cancellations for vested and unvested options that remain outstanding. The risk-free interest rate for the expected term of the option and ESPP is based on the U.S. Treasury yield curve in effect at the time of grant. The Company recognizes its stock-based compensation related to options using a straight-line method over the vesting term of the awards. The Company recognizes its stock-based compensation related to ESPP using a straight-line method over the offering period, which is six months. The fair value of RSUs is the grant date closing price of our common stock. In the first quarter of 2015, the Company granted two types of PRSUs. The fair value of PRSUs, with service and performance conditions, is the grant date closing price of our common stock. The grant date fair value of the PRSUs requiring the satisfaction of service, performance, and market conditions was determined by using a Monte Carlo simulation model, which utilized multiple input variables that determined the probability of satisfying the market condition requirements. The Company recognizes expense related to RSUs using a straight-line method over the vesting term of the awards. The Company recognizes expense for PRSUs, with service and performance conditions, based on the probability of achieving the performance criteria, as defined in the PRSU agreements. The Company recognizes expense for PRSUs with service, performance, and market conditions based on the probability of achieving the performance conditions as long as the requisite service is rendered, even if the market conditions are not met. PRSUs are expensed using the graded vesting attribution method over the requisite service period. The Company records stock-based compensation for options, RSUs and PRSUs granted net of estimated forfeiture rates. The Company estimates forfeiture rates at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical forfeitures to estimate its future forfeiture rates.
