Accounting Policies [Abstract]
Overview and Basis of Presentation	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 data protection solutions. We offer cloud-enabled 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 months ended May 31, 2016 are not necessarily indicative of the results expected for the full fiscal year. The condensed consolidated balance sheet as of February 29, 2016 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 29, 2016 . Foreign Currency 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 gains (losses) resulting from foreign exchange transactions of $0.5 million and $(0.6) million for the three months ended May 31, 2016 and 2015 , respectively, in other income (expense), net in the condensed consolidated statements of operations. We have foreign subsidiaries that operate and sell our products in various markets 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 May 31, 2016 and February 29, 2016 were not significant. The change in the fair value of these foreign currency forward contracts is recorded as gain (loss) in other income (expense), net in the condensed consolidated statements of operations. Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (the "FASB") issued an accounting standard which requires measurement and recognition of expected credit losses for financial assets held. The standard update is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, and early adoption is permitted as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The standard is to be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements. In March 2016, the FASB issued an accounting standard to simplify employee shared-based payment accounting. The standard update is effective for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years, and early adoption is permitted in any interim or annual period. If early adopted in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. Early adoption requires the adoption of all the amendments in the same period. Amendments related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements, and forfeitures should be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is adopted. Amendments related to the presentation of employee taxes paid on the statement of cash flows when an employer withholds shares to meet the minimum statutory withholding requirement should be applied retrospectively. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement and the practical expedient for estimating expected term should be applied prospectively. An entity may elect to apply the amendments related to the presentation of excess tax benefits on the statement of cash flows using either a prospective transition method or a retrospective transition method. We are currently evaluating the timing and the impact of adopting this update on our condensed consolidated financial statements. In March 2016, the FASB issued an accounting standard to eliminate the requirement to retroactively adopt the equity method of accounting for an investment that qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence. The standard update requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. For an available-for-sale equity security that becomes qualified for the equity method of accounting, an entity is required to recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income (loss) at the date the investment becomes qualified for use of the equity method. 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 upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. We do not expect the adoption of this update to have a material impact on our condensed consolidated financial statements. In February 2016, the FASB issued an accounting standard to amend lease accounting requirements and requires entities to generally recognize on the balance sheet operating and financing lease liabilities and corresponding right-of-use assets. The new standard will require significant additional disclosures about the amount, timing and uncertainty of cash flows from leases. The standard update is effective for fiscal years beginning after December 15, 2018 and interim periods within those years, and early adoption is permitted. The standard is to be applied using a modified retrospective approach and includes a number of optional practical expedients that entities may elect to apply. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements and expect that most of our operating lease commitments will be subject to the standard update and recognized as operating lease liabilities and right-of-use assets upon the adoption. In January 2016, 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 May 2014, the FASB issued an accounting standard which completed the joint effort by the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and improving financial reporting, and issued subsequent amendments to the initial guidance collectively under FASB Accounting Standards Codification Topic 606. Topic 606 supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of Topic 606 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. Topic 606 defines a five-step process to achieve this core principle, while more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation, among others. Topic 606 is effective for us as of 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 continuing to evaluate the timing and the impact of adopting this update on our condensed consolidated financial statements.

For the three months ended May 31, 2016 , we realized gross gains of $0.4 million and an insignificant amount of gross losses. For the three months ended May 31, 2015 , realized gains and losses were insignificant. We reflect these gains and losses as a component of other income (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 May 31, 2016 Less Than 12 Months 12 Months or Greater Total Fair Unrealized Fair Value Unrealized Fair Value Unrealized Corporate debt securities $ 10,924 $ (20 ) $ — $ — $ 10,924 $ (20 ) Mortgage-backed securities 1,345 (3 ) 234 (2 ) 1,579 (5 ) U.S. government agency securities 5,332 (27 ) 249 (2 ) 5,581 (29 ) U.S. government notes 570 (2 ) — — 570 (2 ) $ 18,171 $ (52 ) $ 483 $ (4 ) $ 18,654 $ (56 ) As of February 29, 2016 Less Than 12 Months 12 Months or Greater Total Fair Unrealized Fair Value Unrealized Fair Value Unrealized Asset-backed securities $ 1,788 $ (3 ) $ — $ — $ 1,788 $ (3 ) Corporate debt securities 12,088 (22 ) — — 12,088 (22 ) Mortgage-backed securities 1,746 (8 ) 385 (5 ) 2,131 (13 ) U.S. government agency securities 887 (10 ) 622 (4 ) 1,509 (14 ) $ 16,509 $ (43 ) $ 1,007 $ (9 ) $ 17,516 $ (52 ) 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 May 31, 2016 , 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 May 31, 2016 Due in 1 year $ 10,432 Due in 1 year through 5 years 22,147 Due in 5 years through 10 years 1,372 Due after 10 years 3,471 $ 37,422 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.

Business Combinations [Abstract]
Acquisition	Acquisition Sookasa, Inc. In March 2016, we acquired Sookasa, Inc. ("Sookasa"), a provider of encryption, security, and compliance solutions for cloud-based integration partners. We acquired all of the outstanding equity interests of Sookasa for cash consideration of $0.3 million , which included the settlement of the outstanding indebtedness of Sookasa with SVB Financial Group ("SVB"), and the issuance of 10,000 shares of our common stock to SVB in connection with such settlement. The total aggregate consideration, inclusive of cash, debt settlement and equity, was approximately $0.4 million , of which $0.4 million was allocated to goodwill. The goodwill is primarily attributable to the acquired assembled workforce and is not expected to be deductible for income tax purposes. 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. Any changes to the preliminary estimates during the measurement period will be recorded as adjustments to those assets and liabilities and residual amounts will be allocated to goodwill. The final purchase price allocation is dependent upon the finalization of tax studies still in progress. The results of operations, since the acquisition date, were not material to our condensed consolidated results of operations for the three months ended May 31, 2016 . The following unaudited pro forma information presents the combined results of operations of Barracuda and Sookasa as if the acquisition had been completed on March 1, 2015, the beginning of the comparable prior annual reporting period. 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 purposes 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.

In addition to the above, we maintained other intangible assets not subject to amortization of $0.2 million as of May 31, 2016 and February 29, 2016 . Amortization expense, including impairment charges, was $1.9 million and $0.6 million for the three months ended May 31, 2016 and 2015 , respectively. As of May 31, 2016 , amortization expense for intangible assets in future periods was as follows: $5.4 million for the remainder of fiscal 2017 , $6.9 million for fiscal 2018 , $6.0 million for fiscal 2019 , $5.8 million for fiscal 2020 , $5.3 million for fiscal 2021 and $7.9 million thereafter.

Stockholders' Deficit	Stockholders’ Deficit Stock-Based Compensation Total stock-based compensation expense has been classified as follows in the accompanying condensed consolidated statements of operations (in thousands): Three Months Ended May 31, 2016 2015 Cost of revenue $ 298 $ 211 Research and development 2,464 1,835 Sales and marketing 1,848 1,550 General and administrative 3,327 2,948 $ 7,937 $ 6,544 Our 2012 Equity Incentive Plan (the "2012 Plan") authorizes the granting of stock options, stock appreciation rights, restricted stock and restricted stock units ("RSUs") to employees, directors and contractors. 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 May 31, 2016 , net of forecasted forfeitures, there was $15.6 million of unrecognized compensation cost related to outstanding stock options, expected to be recognized over a weighted-average period of 2.45 years and $53.2 million of unrecognized compensation cost related to unvested RSUs, expected to be recognized over a weighted-average period of 3.03 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 6 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 May 31, 2016 , we had reserved 750,000 shares of our common stock for issuance under the ESPP and 715,230 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 May 31, 2016 Total number of shares repurchased 18 Dollar amount of shares repurchased $ 280 Average price paid per share $ 15.91 Remaining amount authorized as of May 31, 2016 $ 30,504 For additional information, see "Part II — Other Information, 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	Income Taxes For the three months ended May 31, 2016 and 2015 , we recorded income tax provision of $3.3 million and $2.4 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 provision that would be derived by applying the statutory rate to our before tax income for the three months ended May 31, 2016 and the income tax provision actually recorded is primarily due to the temporary differences we do not expect to benefit from due to our valuation allowance, as well as non-deductible stock-based compensation expense and other currently non-deductible items.

Segment Reporting [Abstract]
Segment Information	Segment Information Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our chief executive officer. Our chief executive officer reviews financial information presented on a consolidated basis, accompanied by information about sales by geographic region, for purposes of allocating resources and evaluating financial performance. We have one business activity and there are no segment managers who are held accountable for operations, operating results and plans for levels or components below the consolidated level. Accordingly, we have determined that we have a single reportable segment and operating unit structure. Revenue by geographic region is presented as follows (in thousands): Three Months Ended May 31, 2016 2015 North America $ 65,097 $ 56,041 United States 61,593 52,804 Other 3,504 3,237 Latin America 1,125 1,016 Asia-Pacific 5,049 4,655 EMEA 15,383 16,262 $ 86,654 $ 77,974

Commitments and Contingencies	Commitments and Contingencies Legal Matters On April 18, 2016, R. David Hunt, as Seller Representative of stockholders of C2C Systems Limited ("C2C"), filed a lawsuit against us in the Court of Chancery of the State of Delaware, for alleged breach of contract of the Share Purchase Agreement dated August 13, 2014, pursuant to which we acquired all of the assets and liabilities of C2C. We intend to vigorously defend this lawsuit. Given the early stage of the litigation, we are unable to estimate a possible loss or range of possible loss, if any. We may, from time to time, be party to litigation and subject to claims that arise in the ordinary course of business. In addition, third parties may, from time to time, assert claims against us in the form of letters and other communications. We currently believe that these ordinary course matters will not have a material adverse effect on our business, consolidated financial position, results of operations or cash flows; however, the results of litigation and claims are inherently unpredictable. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Accounting Policies [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 data protection solutions. We offer cloud-enabled 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 months ended May 31, 2016 are not necessarily indicative of the results expected for the full fiscal year. The condensed consolidated balance sheet as of February 29, 2016 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 29, 2016 .
Foreign Currency	Foreign Currency 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 gains (losses) resulting from foreign exchange transactions of $0.5 million and $(0.6) million for the three months ended May 31, 2016 and 2015 , respectively, in other income (expense), net in the condensed consolidated statements of operations. We have foreign subsidiaries that operate and sell our products in various markets 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 May 31, 2016 and February 29, 2016 were not significant. The change in the fair value of these foreign currency forward contracts is recorded as gain (loss) in other income (expense), net in the condensed consolidated statements of operations.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (the "FASB") issued an accounting standard which requires measurement and recognition of expected credit losses for financial assets held. The standard update is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, and early adoption is permitted as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The standard is to be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements. In March 2016, the FASB issued an accounting standard to simplify employee shared-based payment accounting. The standard update is effective for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years, and early adoption is permitted in any interim or annual period. If early adopted in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. Early adoption requires the adoption of all the amendments in the same period. Amendments related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements, and forfeitures should be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is adopted. Amendments related to the presentation of employee taxes paid on the statement of cash flows when an employer withholds shares to meet the minimum statutory withholding requirement should be applied retrospectively. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement and the practical expedient for estimating expected term should be applied prospectively. An entity may elect to apply the amendments related to the presentation of excess tax benefits on the statement of cash flows using either a prospective transition method or a retrospective transition method. We are currently evaluating the timing and the impact of adopting this update on our condensed consolidated financial statements. In March 2016, the FASB issued an accounting standard to eliminate the requirement to retroactively adopt the equity method of accounting for an investment that qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence. The standard update requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. For an available-for-sale equity security that becomes qualified for the equity method of accounting, an entity is required to recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income (loss) at the date the investment becomes qualified for use of the equity method. 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 upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. We do not expect the adoption of this update to have a material impact on our condensed consolidated financial statements. In February 2016, the FASB issued an accounting standard to amend lease accounting requirements and requires entities to generally recognize on the balance sheet operating and financing lease liabilities and corresponding right-of-use assets. The new standard will require significant additional disclosures about the amount, timing and uncertainty of cash flows from leases. The standard update is effective for fiscal years beginning after December 15, 2018 and interim periods within those years, and early adoption is permitted. The standard is to be applied using a modified retrospective approach and includes a number of optional practical expedients that entities may elect to apply. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements and expect that most of our operating lease commitments will be subject to the standard update and recognized as operating lease liabilities and right-of-use assets upon the adoption. In January 2016, 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 May 2014, the FASB issued an accounting standard which completed the joint effort by the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and improving financial reporting, and issued subsequent amendments to the initial guidance collectively under FASB Accounting Standards Codification Topic 606. Topic 606 supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of Topic 606 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. Topic 606 defines a five-step process to achieve this core principle, while more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation, among others. Topic 606 is effective for us as of 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 continuing to evaluate the timing and 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.
Segment Information	Segment Information Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our chief executive officer. Our chief executive officer reviews financial information presented on a consolidated basis, accompanied by information about sales by geographic region, for purposes of allocating resources and evaluating financial performance. We have one business activity and there are no segment managers who are held accountable for operations, operating results and plans for levels or components below the consolidated level. Accordingly, we have determined that we have a single reportable segment and operating unit structure.
