Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview and Basis of Presentation	1. Overview and Basis of Presentation Nature of Operations Barracuda Networks, Inc., also referred to in this report as “we,” “our,” “us,” “Barracuda” or “the Company,” is headquartered in Campbell, California, and designs and delivers powerful yet easy-to-use security and storage solutions. We offer cloud-connected solutions that help our customers address security threats, improve network performance and protect and store their data. Our solutions are designed to simplify IT operations for our customers, allowing them to enhance their return on technology investments. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We evaluate our estimates on an ongoing basis, including those related to the fair values of stock-based awards, income taxes and contingent liabilities, among others. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates and such differences could be material to our condensed consolidated financial position and results of operations. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP, and follow the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP are condensed or omitted. In management’s opinion, the unaudited condensed financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of our financial information. The results for the three and nine months ended November 30, 2015 are not necessarily indicative of the results expected for the full fiscal year. The condensed consolidated balance sheet as of February 28, 2015 has been derived from audited financial statements at that date but does not include all of the information required by GAAP. The accompanying unaudited condensed consolidated financial statements include the accounts of Barracuda Networks, Inc. and our wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited financial statements and related footnotes included in our most recent Annual Report on Form 10-K. There have been no material changes in our significant accounting policies from those that were disclosed in our Annual Report on Form 10-K for the fiscal year ended February 28, 2015. Foreign Currency We have foreign subsidiaries that operate and sell our products and services in various countries and jurisdictions around the world. As a result, we are exposed to foreign exchange risks. We utilize foreign exchange forward contracts to manage foreign currency risk associated with foreign currency denominated monetary assets and liabilities, primarily trade receivables, and to reduce the volatility of earnings and cash flows related to foreign currency transactions. The fair values of our contracts as of November 30, 2015 and February 28, 2015 were not significant. The change in the fair value of these foreign currency forward contracts is recorded as gain (loss) in other expense, net in the condensed consolidated statement of operations. For those subsidiaries whose functional currency is not the U.S. dollar, assets and liabilities are translated into U.S. dollar equivalents at the exchange rate in effect on the balance sheet date and revenues and expenses are translated into U.S. dollars using the average exchange rate over the period. Resulting currency translation adjustments are recorded in accumulated other comprehensive loss in the condensed consolidated balance sheets. We recorded net losses resulting from foreign exchange transactions of $0.4 million and $0.9 million for the three and nine months ended November 30, 2015, respectively. We recorded net losses resulting from foreign exchange transactions of $1.7 million and $2.4 million for the three and nine months ended November 30, 2014, respectively. Recent Accounting Pronouncements In January 2016, the Financial Accounting Standards Board (the “FASB”) issued an accounting standard to enhance the reporting model for financial instruments by amending certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The standard update is effective for fiscal years beginning after December 15, 2017 and interim periods within those years. Early application to financial statements of fiscal years or interim periods that have not yet been issued is permitted by presenting separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk if we elected to measure the liability at fair value in accordance with the fair value option for financial instruments, otherwise, early adoption is not permitted. The standard is to be applied with a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements. In November 2015, the FASB issued an accounting standard to simplify the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current in a classified statement of financial position, which would be a change from our historical presentation whereby certain of our deferred tax assets and liabilities were classified as current and the remainder were classified as non-current. The standard update is effective for fiscal years beginning after December 15, 2016 and interim periods within those years, and early adoption is permitted. The standard is to be applied either prospectively to all deferred tax assets and liabilities or retrospectively to all periods presented. We do not expect the adoption of this standard to have a material impact on our condensed consolidated financial statements. In September 2015, the FASB issued an accounting standard to simplify the accounting for measurement period adjustments in connection with business combinations by requiring that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The standard update is effective for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years. The standard update is to be applied prospectively to adjustments of provisional amounts that occur after the effective date with earlier application permitted for financial statements that have not been issued. We do not expect the adoption of this standard to have an impact on our condensed consolidated financial statements. In July 2015, the FASB issued an accounting standard to simplify the measurement of inventory by changing the subsequent measurement guidance from the lower of cost or market to the lower of cost and net realizable value for inventory. The standard update is effective for fiscal years beginning after December 15, 2016 and interim periods within those years, and early adoption is permitted. The standard is to be applied prospectively. We do not expect the adoption of this standard to have an impact on our condensed consolidated financial statements. In May 2014, the FASB issued an accounting standard which completes the joint effort by the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and improving financial reporting by creating common revenue recognition guidance for GAAP and International Financial Reporting Standards. The core principle of this update is that an entity should 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 goods or services. The original effective date would have required us to adopt this update in the first quarter of fiscal 2018. However, in July 2015, the FASB amended the standard to provide a one-year deferral of the effective date, as well as providing the option to early adopt the standard on the original effective date. Accordingly, we may adopt the standard in either the first quarter of fiscal 2018 or the first quarter of fiscal 2019. The standard allows for full retrospective adoption applied to all periods presented or retrospective adoption with the cumulative effect of initially applying this update recognized at the date of initial application. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements.

Such realized gains and losses were insignificant for each of the three and nine months ended November 30, 2015 and 2014. We reflect these gains and losses as a component of other expense, net in the condensed consolidated statements of operations. The following tables present gross unrealized losses and fair values for those marketable securities that were in an unrealized loss position aggregated by investment category and the length of time that individual securities have been in a continuous loss position (in thousands): As of November 30, 2015 Less Than 12 Months 12 Months or Greater Total Fair Unrealized Fair Value Unrealized Fair Value Unrealized Asset-backed securities $ 2,833 $ (5 ) $ — $ — $ 2,833 $ (5 ) Corporate debt securities 11,180 (19 ) — — 11,180 (19 ) Foreign government bonds 206 (1 ) — — 206 (1 ) Mortgage-backed securities 1,576 (10 ) 207 (2 ) 1,783 (12 ) U.S. government agency securities 906 (11 ) 621 (14 ) 1,527 (25 ) U.S. government notes 3,090 (11 ) — — 3,090 (11 ) $ 19,791 $ (57 ) $ 828 $ (16 ) $ 20,619 $ (73 ) As of February 28, 2015 Less Than 12 Months 12 Months or Greater Total Fair Unrealized Fair Value Unrealized Fair Value Unrealized Asset-backed securities $ 2,385 $ (4 ) $ — $ — $ 2,385 $ (4 ) Corporate debt securities 11,346 (13 ) — — 11,346 (13 ) Equity securities 978 (32 ) — — 978 (32 ) Mortgage-backed securities 1,923 (10 ) — — 1,923 (10 ) U.S. government agency securities 4,331 (24 ) — — 4,331 (24 ) $ 20,963 $ (83 ) $ — $ — $ 20,963 $ (83 ) We periodically review our marketable securities for other-than-temporary impairment. We consider factors such as the duration, severity and the reason for the decline in value, the potential recovery period and whether we intend to sell. For marketable debt securities, we also consider whether (i) it is more likely than not that we will be required to sell the debt securities before recovery of their amortized cost basis, and (ii) the amortized cost basis cannot be recovered as a result of credit losses. Unrealized losses related to these investments are due to interest rate fluctuations as opposed to changes in credit quality. We do not intend to sell and it is not more likely than not that we would be required to sell these investments before recovery of their amortized cost basis, which may be at maturity. As of November 30, 2015, we have recognized no other-than-temporary impairment loss. The following table summarizes the estimated fair value of our investments in marketable debt securities by contractual maturities (in thousands): As of Due in 1 year $ 13,700 Due in 1 year through 5 years 14,023 Due in 5 years through 10 years 729 Due after 10 years 4,166 $ 32,618 Fair Value Measurements We determine fair value based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value assumes that the transaction to sell the asset or transfer the liability occurs in the principal or most advantageous market for the asset or liability and establishes that the fair value of an asset or liability shall be determined based on the assumptions that market participants would use in pricing the asset or liability. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. The fair value hierarchy prioritizes the inputs into three levels that may be used to measure fair value: Level 1: Inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2: Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3: Inputs are unobservable inputs based on our assumptions. Cash equivalents and marketable equity securities are classified within Level 1 because they are valued using quoted market prices or alternative pricing sources and models utilizing market observable inputs. Marketable debt securities and derivative assets are classified within Level 2 if the investments are valued using model driven valuations which use observable inputs such as quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. Our marketable securities are held by custodians who obtain investment prices from a third-party pricing provider that incorporates standard inputs in various asset price models. We estimated the fair value of our Level 3 contingent consideration liabilities based on a weighted probability assessment of achieving the milestones related to certain of our acquisitions. Significant increases (decreases) in the probability assumptions in isolation would result in a significantly higher (lower) fair value measurement.

Investments in Non-Marketable Equity Security In the three months ended November 30, 2015, we invested approximately $1.0 million in stock of a privately-held company, which was accounted for under the cost method. As of February 28, 2015, we have invested approximately $1.3 million in stock of a private company, which was accounted for under the equity method. We recognize our proportional share of earnings and losses of the investee in our financial statements and adjust the carrying amount of our investment accordingly. In August 2015, we acquired additional shares of stock in the privately-held company for approximately $0.4 million to maintain our approximately 24% ownership interest. For the three and nine months ended November 30, 2015, our proportionate share of the investee’s losses was $0.1 million and $0.3 million, respectively. For the three and nine months ended November 30, 2014, our proportionate share was not material. The investment is classified in other non-current assets in our condensed consolidated balance sheets.

Business Combinations [Abstract]
Acquisitions	3. Acquisitions Intronis, Inc. In October 2015, we acquired Intronis, Inc. (“Intronis”), a leader in providing data protection solutions to managed service providers. We acquired all of the outstanding equity interests of Intronis for aggregate purchase consideration of $65.4 million in cash, subject to certain adjustments set forth in an Agreement and Plan of Merger. $7.0 million of the purchase consideration is being held back for potential indemnification obligations of the equityholders of Intronis. We recorded the assets acquired and liabilities assumed at their estimated fair value, with the difference between the fair value of the net assets acquired and the purchase consideration reflected as goodwill. The following table reflects the fair values of assets acquired and liabilities assumed as of the acquisition date (in thousands): Cash $ 2,327 Accounts receivable 376 Other current assets 654 Property and equipment 4,203 Other non-current assets 750 Developed technology 21,500 Customer relationships 11,870 Trade name 300 Goodwill 29,989 Accounts payable (685 ) Accrued expenses (1,149 ) Deferred revenue (current) (649 ) Deferred tax liabilities (4,046 ) Total value of assets acquired and liabilities assumed $ 65,440 The fair values of assets acquired and liabilities assumed were based on a preliminary valuation and our estimates and assumptions are subject to change within the measurement period of one year from the acquisition date. The primary areas of the purchase price allocation that are not yet finalized are related to the valuation of deferred income taxes and residual goodwill. As of the acquisition date, Intronis’ developed technology, customer relationships and trade name had weighted-average useful lives of 7.0 years, 7.0 years and 4.0 years, respectively. The total weighted-average useful life of these acquired intangible assets is 7.0 years. The goodwill is primarily attributed to the synergies expected to be realized following the acquisition. Goodwill is not expected to be deductible for income tax purposes. Included in our results of operations for the nine months ended November 30, 2015 are $3.2 million and $0.7 million of revenue and net loss, respectively, attributable to Intronis since the acquisition. The following unaudited pro forma information presents the combined results of operations of Barracuda and Intronis as if the acquisition had been completed on March 1, 2014, the beginning of the comparable prior annual reporting period. The unaudited pro forma information includes (i) amortization associated with preliminary estimates for the acquired intangible assets; and (ii) the associated tax impact on these unaudited pro forma adjustments and certain changes in judgment of valuation allowance as a combined business. The unaudited pro forma information does not reflect any cost saving synergies from operating efficiencies or the effect of the incremental costs incurred in integrating the two companies. Accordingly, this unaudited pro forma information is presented for informational purpose only and is not necessarily indicative of what the actual results of operations of the combined company would have been if the acquisition had occurred at the beginning of the period presented, nor are they indicative of future results of operations.

The goodwill is primarily attributed to the synergies expected to be realized following the acquisition and is expected to be deductible for income tax purposes. As of the acquisition date, customer relationships and developed technology had weighted-average useful lives of 7.0 years and 1.0 years, respectively. The results of operations, since the acquisition date, and pro forma information were not material to our condensed consolidated results of operations for the three and nine months ended November 30, 2015.

Amortization expense was $1.3 million and $2.5 million for the three and nine months ended November 30, 2015, respectively, and $0.8 million and $2.9 million for the three and nine months ended November 30, 2014, respectively. As of November 30, 2015, amortization expense for intangible assets in future periods was as follows: $1.8 million for the remainder of fiscal 2016, $7.1 million for fiscal 2017, $6.8 million for fiscal 2018, $5.9 million for fiscal 2019, $5.6 million for fiscal 2020 and $13.6 million thereafter.

Options granted are exercisable for periods not to exceed 10 years. Options and RSUs granted typically vest over four years contingent upon employment or service with us on the vesting date. As of November 30, 2015, net of forecasted forfeitures, there was $21.3 million of unrecognized compensation cost related to outstanding stock options, expected to be recognized over a weighted-average period of 2.67 years and $52.2 million of unrecognized compensation cost related to unvested RSUs, expected to be recognized over a weighted-average period of 3.19 years. To the extent the actual forfeiture rate is different from what management has anticipated, stock-based compensation expense related to these equity awards will be different from management’s expectations. Our 2015 Employee Stock Purchase Plan (the “ESPP”) allows eligible employee participants to purchase shares of our common stock at a discount through payroll deductions. The ESPP consists of offering periods that are approximately six months in length and employees may purchase shares in each period at 85% of the lower of the Company’s fair market value on the first trading day of each offering period or on the purchase date. The ESPP will continue until the earlier to occur of (i) the termination of the ESPP by our board of directors, or (ii) June 15, 2035. As of November 30, 2015, we had reserved 750,000 shares of our common stock for issuance under the ESPP and all such shares remain available for future issuance. Stock Repurchase Program In September 2015, our board of directors authorized a stock repurchase program to repurchase shares of our common stock for an aggregate purchase price not to exceed $50.0 million through September 30, 2017. The stock repurchase program does not obligate us to repurchase any specific dollar amount or to acquire any specific number of shares. Stock will be purchased from time to time, in the open market or through private transactions, subject to market condition, in compliance with applicable state and federal securities laws. The timing and amount of repurchases, if any, will depend upon several factors, including market and business conditions, the trading price of our common stock and the nature of other investment opportunities. The following table summarizes our common stock repurchases for the period presented (in thousands, except per share data): Three Months Ended November 30, 2015 Total number of shares repurchased 430 Dollar amount of shares repurchased $ 8,000 Average price paid per share $ 18.60 Remaining amount authorized as of November 30, 2015 $ 42,000 For additional information, see “Item 2 - Unregistered Sales of Equity Securities and Use of Proceeds” of this Quarterly Report on Form 10-Q.

Income Tax Disclosure [Abstract]
Income Taxes	6. Income Taxes For the three and nine months ended November 30, 2015, we recorded income tax benefits of $6.8 million and $2.3 million, respectively. For the three and nine months ended November 30, 2014, we recorded income tax benefits of $3.3 million and $3.0 million, respectively. In fiscal 2015, we established a valuation allowance against a significant portion of our deferred tax assets, including U.S. federal and state deferred tax assets and certain foreign deferred tax assets, because realization of these tax benefits through future taxable income did not meet the more-likely-than-not threshold. We intend to maintain the valuation allowances until sufficient positive evidence exists to support its reversal. The difference between the income tax benefit that would be derived by applying the statutory rate to our before tax loss for the nine months ended November 30, 2015 and the income tax benefit actually recorded is primarily due to the release of a portion of our valuation allowance equal to the Intronis net purchase accounting deferred tax liability associated with the acquired intangible assets which provide a source of future taxable income supporting the recognition of our existing deferred tax assets, the increase to a net operating loss carryback related to the prior year offset by temporary differences we did not benefit from during the period due to our valuation allowance.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	8. Commitments and Contingencies Legal Matters In late 2011, following a voluntary internal review of our compliance with U.S. export control and sanctions laws, our management team became aware that certain of our physical appliances had been sold indirectly into embargoed countries via our distributors and resellers, potentially in violation of U.S. export control and economic sanctions laws. In addition, certain of our solutions incorporate encryption components and may be exported from the United States only with the required approvals; in the past, we may have exported products prior to receiving these required authorizations. After completion of a comprehensive internal investigation conducted by outside counsel, we submitted voluntary disclosures regarding these matters to the U.S. Commerce Department, Bureau of Industry and Security (“BIS”), and to the U.S. Treasury Department, Office of Foreign Assets Control (“OFAC”). These disclosures summarized potential violations of export controls and economic sanctions laws, including reexports by third parties and provision of services to end users in embargoed countries including Iran, Sudan and Syria. In May 2015, we agreed to a settlement with OFAC pursuant to which we agreed to pay $38,930 as consideration for the final resolution of all issues related to the voluntary disclosure that we submitted to OFAC. In November 2015, we agreed to a settlement with BIS pursuant to which we agreed to pay $1.5 million as consideration for the final resolution of all issues related to the voluntary disclosure that we submitted to BIS. On January 23, 2015, Wetro Lan LLC (“Wetro Lan”) filed a lawsuit against us in the U.S. District Court for the Eastern District of Texas, Marshall Division, Wetro Lan LLC v. Barracuda Networks, Inc., Case No. 2:15-CV-46, alleging that certain of our products infringe U.S. Pat. No. 6,795,918. We were notified by RPX Corporation (“RPX”) that it had entered into a settlement and license agreement with Wetro Lan for the patents in the lawsuit. As a result, the lawsuit was dismissed with prejudice on November 11, 2015 and we did not pay any fees associated with the settlement and license. From time to time, we are party to litigation and subject to claims that arise in the ordinary course of our business, including actions with respect to employment claims and other matters. Although the results of litigation and claims are inherently unpredictable, we believe that the final outcome of such matters will not have a material adverse effect on our business, consolidated financial position, results of operations or cash flows.

Subsequent Events [Abstract]
Subsequent Event	10. Subsequent Event In December 2015, we entered into an intellectual property settlement agreement (the “Agreement”), whereby we resolved all current and potential future claims between us and a third party. Under the terms of the Agreement, we agreed to make certain future settlement payments in exchange for a worldwide license for certain patents for the life of the patents, and related patents acquired within three years of the Agreement’s effective date; and a covenant not to sue for infringement of any such licensed patents. We accounted for the Agreement as a multiple-element arrangement and allocated the fair value of the consideration to the identifiable elements based on their estimated fair values. We determined that the primary benefit of the arrangement is avoided litigation costs and the release of any potential past claims. $2.3 million was allocated to the resolution of any past claims and recorded as a legal settlement charge within general and administrative expense in the three months ended November 30, 2015.

Overview and Basis of Present18

Overview and Basis of Presentation (Policies)	9 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations Barracuda Networks, Inc., also referred to in this report as “we,” “our,” “us,” “Barracuda” or “the Company,” is headquartered in Campbell, California, and designs and delivers powerful yet easy-to-use security and storage solutions. We offer cloud-connected solutions that help our customers address security threats, improve network performance and protect and store their data. Our solutions are designed to simplify IT operations for our customers, allowing them to enhance their return on technology investments.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We evaluate our estimates on an ongoing basis, including those related to the fair values of stock-based awards, income taxes and contingent liabilities, among others. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates and such differences could be material to our condensed consolidated financial position and results of operations.
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP, and follow the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP are condensed or omitted. In management’s opinion, the unaudited condensed financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of our financial information. The results for the three and nine months ended November 30, 2015 are not necessarily indicative of the results expected for the full fiscal year. The condensed consolidated balance sheet as of February 28, 2015 has been derived from audited financial statements at that date but does not include all of the information required by GAAP. The accompanying unaudited condensed consolidated financial statements include the accounts of Barracuda Networks, Inc. and our wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited financial statements and related footnotes included in our most recent Annual Report on Form 10-K. There have been no material changes in our significant accounting policies from those that were disclosed in our Annual Report on Form 10-K for the fiscal year ended February 28, 2015.
Foreign Currency	Foreign Currency We have foreign subsidiaries that operate and sell our products and services in various countries and jurisdictions around the world. As a result, we are exposed to foreign exchange risks. We utilize foreign exchange forward contracts to manage foreign currency risk associated with foreign currency denominated monetary assets and liabilities, primarily trade receivables, and to reduce the volatility of earnings and cash flows related to foreign currency transactions. The fair values of our contracts as of November 30, 2015 and February 28, 2015 were not significant. The change in the fair value of these foreign currency forward contracts is recorded as gain (loss) in other expense, net in the condensed consolidated statement of operations. For those subsidiaries whose functional currency is not the U.S. dollar, assets and liabilities are translated into U.S. dollar equivalents at the exchange rate in effect on the balance sheet date and revenues and expenses are translated into U.S. dollars using the average exchange rate over the period. Resulting currency translation adjustments are recorded in accumulated other comprehensive loss in the condensed consolidated balance sheets. We recorded net losses resulting from foreign exchange transactions of $0.4 million and $0.9 million for the three and nine months ended November 30, 2015, respectively. We recorded net losses resulting from foreign exchange transactions of $1.7 million and $2.4 million for the three and nine months ended November 30, 2014, respectively.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In January 2016, the Financial Accounting Standards Board (the “FASB”) issued an accounting standard to enhance the reporting model for financial instruments by amending certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The standard update is effective for fiscal years beginning after December 15, 2017 and interim periods within those years. Early application to financial statements of fiscal years or interim periods that have not yet been issued is permitted by presenting separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk if we elected to measure the liability at fair value in accordance with the fair value option for financial instruments, otherwise, early adoption is not permitted. The standard is to be applied with a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements. In November 2015, the FASB issued an accounting standard to simplify the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current in a classified statement of financial position, which would be a change from our historical presentation whereby certain of our deferred tax assets and liabilities were classified as current and the remainder were classified as non-current. The standard update is effective for fiscal years beginning after December 15, 2016 and interim periods within those years, and early adoption is permitted. The standard is to be applied either prospectively to all deferred tax assets and liabilities or retrospectively to all periods presented. We do not expect the adoption of this standard to have a material impact on our condensed consolidated financial statements. In September 2015, the FASB issued an accounting standard to simplify the accounting for measurement period adjustments in connection with business combinations by requiring that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The standard update is effective for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years. The standard update is to be applied prospectively to adjustments of provisional amounts that occur after the effective date with earlier application permitted for financial statements that have not been issued. We do not expect the adoption of this standard to have an impact on our condensed consolidated financial statements. In July 2015, the FASB issued an accounting standard to simplify the measurement of inventory by changing the subsequent measurement guidance from the lower of cost or market to the lower of cost and net realizable value for inventory. The standard update is effective for fiscal years beginning after December 15, 2016 and interim periods within those years, and early adoption is permitted. The standard is to be applied prospectively. We do not expect the adoption of this standard to have an impact on our condensed consolidated financial statements. In May 2014, the FASB issued an accounting standard which completes the joint effort by the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and improving financial reporting by creating common revenue recognition guidance for GAAP and International Financial Reporting Standards. The core principle of this update is that an entity should 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 goods or services. The original effective date would have required us to adopt this update in the first quarter of fiscal 2018. However, in July 2015, the FASB amended the standard to provide a one-year deferral of the effective date, as well as providing the option to early adopt the standard on the original effective date. Accordingly, we may adopt the standard in either the first quarter of fiscal 2018 or the first quarter of fiscal 2019. The standard allows for full retrospective adoption applied to all periods presented or retrospective adoption with the cumulative effect of initially applying this update recognized at the date of initial application. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements.
Fair Value Measurements	Fair Value Measurements We determine fair value based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value assumes that the transaction to sell the asset or transfer the liability occurs in the principal or most advantageous market for the asset or liability and establishes that the fair value of an asset or liability shall be determined based on the assumptions that market participants would use in pricing the asset or liability. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. The fair value hierarchy prioritizes the inputs into three levels that may be used to measure fair value: Level 1: Inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2: Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3: Inputs are unobservable inputs based on our assumptions. Cash equivalents and marketable equity securities are classified within Level 1 because they are valued using quoted market prices or alternative pricing sources and models utilizing market observable inputs. Marketable debt securities and derivative assets are classified within Level 2 if the investments are valued using model driven valuations which use observable inputs such as quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. Our marketable securities are held by custodians who obtain investment prices from a third-party pricing provider that incorporates standard inputs in various asset price models. We estimated the fair value of our Level 3 contingent consideration liabilities based on a weighted probability assessment of achieving the milestones related to certain of our acquisitions. Significant increases (decreases) in the probability assumptions in isolation would result in a significantly higher (lower) fair value measurement. In developing these estimates, we considered unobservable inputs that are supported by little or no market activity and reflect our own assumptions.
Investment in Non-Marketable Equity Security	Investments in Non-Marketable Equity Security In the three months ended November 30, 2015, we invested approximately $1.0 million in stock of a privately-held company, which was accounted for under the cost method. As of February 28, 2015, we have invested approximately $1.3 million in stock of a private company, which was accounted for under the equity method. We recognize our proportional share of earnings and losses of the investee in our financial statements and adjust the carrying amount of our investment accordingly. In August 2015, we acquired additional shares of stock in the privately-held company for approximately $0.4 million to maintain our approximately 24% ownership interest.
Segment Information	Our chief operating decision maker reviews the financial information presented on a consolidated basis for purposes of allocating resources and evaluating our financial performance. Accordingly, we have determined that we operate in a single reporting segment.
