Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business	Business Our Company Alteryx, Inc. and its subsidiaries, or we, our, or us, is a leader in Analytic Process Automation, or APA. The Alteryx APA software platform unifies analytics, data science and business process automation in one self-service platform to accelerate digital transformation, deliver high-impact business outcomes, accelerate the democratization of data and rapidly upskill modern workforces. Data workers, regardless of technical acumen, are empowered to be curious and solve problems. With the Alteryx APA software platform, users can automate the full range of analytics, data science and processes, embed intelligent decision-making and actions, and empower their organization to deliver faster and better business outcomes. Basis of Presentation Our unaudited interim condensed consolidated financial statements are presented in accordance with accounting standards generally accepted in the United States of America, or U.S. GAAP, for interim financial information. Certain information and disclosures normally included in consolidated financial statements presented in accordance with U.S. GAAP have been condensed or omitted. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission, or SEC, on February 14, 2020. The unaudited interim condensed consolidated financial statements have been prepared on a basis consistent with that used to prepare the audited annual consolidated financial statements and reflect all adjustments which are, in the opinion of our management, of a normal recurring nature and necessary for a fair statement of the condensed consolidated financial statements. All intercompany accounts and transactions have been eliminated in consolidation. The operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results expected for the full year ending December 31, 2020.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies There have been no changes to our accounting policies disclosed in our audited consolidated financial statements and the related notes for the year ended December 31, 2019, other than, during the three months ended March 31, 2020, we adopted new accounting guidance related to the measurement of credit losses and implementation costs incurred in cloud computing arrangements. See Recently Adopted Accounting Pronouncements below and Note 6, Allowance for Doubtful Accounts and Sales Reserves , for additional information. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates and assumptions. On an ongoing basis, our management evaluates these estimates and assumptions, including those related to determination of standalone selling prices of our products and services, allowance for doubtful account and sales reserves, income tax valuations, stock-based compensation, goodwill, and intangible assets valuations and recoverability. We base our estimates on historical data and experience, as well as various other factors that our management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities. Due to the COVID-19 pandemic, there has been uncertainty and disruption in the global economy and financial markets. Except for the increase in expected credit losses as discussed in Note 6, Allowance for Doubtful Accounts and Sales Reserves, and recognition of a full valuation allowance against our deferred tax assets as discussed in Note 12, Income Taxes , we are not aware of any specific event or circumstance that would require an update to our estimates or assumptions or a revision of the carrying value of our assets or liabilities as of the date of this Quarterly Report on Form 10-Q. These estimates and assumptions may change as new events occur and additional information is obtained. As a result, actual results could differ materially from these estimates and assumptions. Operating Segments Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the Chief Operating Decision Maker, or CODM, who is our chief executive officer, in deciding how to allocate resources and assess our financial and operational performance. Our CODM evaluates our financial information and resources and assesses the performance of these resources on a consolidated and aggregated basis. As a result, we have determined that our business operates in a single operating segment. Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2016-13, Financial Instruments - Credit Losses , or ASC 326. The new standard amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology. As a result, we are now required to use a forward-looking expected credit loss model for accounts receivables and other commitments to extend credit. Through December 31, 2019, we calculated our allowance for credit losses using a single pool of trade receivables as the basis for our credit loss rate. Effective January 1, 2020, we adopted ASC 326 and made changes to our accounting policies related to credit loss calculations, including the consideration of forecasted economic data and the pooling of financial assets with similar risk profiles, and now recognize credit losses associated with our available-for-sale securities. We adopted the new allowance for credit losses accounting standard on January 1, 2020 by means of a cumulative-effect adjustment, where we recognized the cumulative effect of initially applying the guidance as a $0.6 million addition to our contract asset reserve with an offsetting adjustment to retained earnings. See Note 5, Fair Value Measurements and Note 6, Allowance for Doubtful Accounts and Sales Reserves , for additional details. In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract , which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing costs incurred to develop or obtain internal-use software. We adopted this standard prospectively effective January 1, 2020. As a result of the adoption, we are required to capitalize additional costs related to the implementation of cloud computing arrangements that we have historically expensed as incurred, particularly costs incurred during the application development phase. This policy aligns the accounting for implementation costs associated with cloud computing arrangements with our existing policy related to internal-use software. Capitalized costs related to cloud computing arrangements for the six months ended June 30, 2020, which are included in prepaid expenses and other current assets on our condensed consolidated balance sheets, were not material.

Revenue	Revenue Disaggregation of Revenue The disaggregation of revenue by region was as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Revenue by region: United States $ 65,969 $ 57,782 $ 146,504 $ 110,678 International 30,264 24,261 58,560 47,385 Total $ 96,233 $ 82,043 $ 205,064 $ 158,063 Revenue attributable to the United Kingdom comprised 10.4% of total revenue for the three months ended June 30, 2020. Other than the United Kingdom for the three months ended June 30, 2020, no other countries outside the United States comprised more than 10% of revenue for any of the periods presented. Our operations outside the United States include sales offices in Australia, Canada, the Czech Republic, France, Germany, Japan, Singapore, the United Arab Emirates, and the United Kingdom, and a research and development center in Ukraine and the Czech Republic. Revenue by location is determined by the billing address of the customer. Revenue recognized on our subscription-based software licenses is recognized at a point in time when the platform is first made available to the customer, or the beginning of the subscription term, if later. Revenue recognized related to post-contract support, or PCS, service, and hosted services is recognized ratably over the subscription term, with the exception of professional services related to training services. Revenue related to professional services is recognized at a point in time as the services are performed and represents 5% or less of total revenue for all periods presented. Contract Assets and Contract Liabilities Timing may differ between the satisfaction of performance obligations and the invoicing and collection of amounts related to our contracts with customers. Contract assets primarily relate to unbilled amounts for contracts with customers for which the amount of revenue recognized exceeds the amount billed to the customer. Contract assets are transferred to accounts receivable when the right to invoice becomes unconditional. Contract liabilities, or deferred revenue, are recorded for amounts that are collected in advance of the satisfaction of performance obligations. These liabilities are classified as current and non-current deferred revenue. As of June 30, 2020, our contract assets are expected to be transferred to receivables within the next 12 to 24 months and, with respect to these contract assets, $24.7 million is included in prepaid expenses and other current assets and $57.4 million is included in other assets on our condensed consolidated balance sheet. As of December 31, 2019, we had contract assets of $18.5 million included in prepaid expenses and other current assets and $39.3 million included in other assets on our consolidated balance sheet. There were no impairments of contract assets during the three and six months ended June 30, 2020. During the six months ended June 30, 2020 and 2019, we recognized $59.8 million and $58.0 million, respectively, of revenue related to amounts that were included in deferred revenue as of December 31, 2019 and 2018, respectively. Assets Recognized from the Costs to Obtain our Contracts with Customers We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. This primarily consists of sales commissions and partner referral fees that are earned upon execution of the related contracts. We amortize these deferred commissions, which include partner referral fees, proportionate with related revenues over the benefit period. A summary of the activity impacting our deferred commissions during the six months ended June 30, 2020 is presented below (in thousands): Balances at December 31, 2019 $ 43,035 Additional deferred commissions 15,862 Amortization of deferred commissions (16,077) Effects of foreign currency translation (681) Balances at June 30, 2020 $ 42,139 As of June 30, 2020, $19.0 million of our deferred commissions are expected to be amortized within the next 12 months and therefore are included in prepaid expenses and other current assets. The remaining amount of our deferred commissions is included in other assets. There were no impairments of assets related to deferred commissions during the six months ended June 30, 2020. There were no assets recognized related to the costs to fulfill contracts during the six months ended June 30, 2020 as these costs were not material. Remaining Performance Obligations Transaction price allocated to the remaining performance obligations represents contracted revenue that has not yet been recognized, which includes deferred revenue on our condensed consolidated balance sheets and unbilled amounts that will be recognized as revenue in future periods. As of June 30, 2020, we had an aggregate transaction price of $410.0 million allocated to unsatisfied performance obligations related primarily to PCS, cloud-based offerings, and subscriptions to third-party syndicated data. We expect to recognize $366.3 million as revenue over the next 24 months, with the remaining amount recognized thereafter.

Business Combinations [Abstract]
Business Combinations	Business Combinations On April 4, 2019, we acquired 100% of the outstanding equity of ClearStory Data Inc., a Delaware corporation, or ClearStory Data, pursuant to an Agreement and Plan of Merger, or the ClearStory Merger Agreement, dated as of March 28, 2019. The acquisition was made to augment our research and development team and acquire certain developed technology. The aggregate consideration payable in exchange for all of the outstanding equity interests of ClearStory Data was $19.6 million in cash, subject to customary adjustments set forth in the ClearStory Merger Agreement. The acquisition of ClearStory Data included $3.0 million of cash consideration held back for customary indemnification matters for a period of 18 months following the acquisition date, which is included in accrued expenses and other current liabilities on our condensed consolidated balance sheets as of June 30, 2020. In connection with the acquisition, we entered into employment agreements with certain employees from ClearStory Data, which include up to $6.0 million in equity awards that vest over a three The condensed consolidated financial statements include the results of operations of ClearStory Data commencing as of the acquisition date. The purchase consideration for the acquisition of $19.6 million consisted of $10.7 million in developed technology, $9.5 million of goodwill, which is tax deductible, and $0.6 million of net liabilities assumed. Goodwill represents the excess of the purchase price consideration over the fair value of the underlying intangible assets and net liabilities assumed. We believe the amount of goodwill resulting from the acquisition is primarily attributable to expected synergies from an assembled workforce, increased development capabilities, offerings to customers, and enhanced opportunities for growth and innovation. We determined the fair value of the developed technology acquired using the replacement cost method which uses estimated costs to recreate the technology. This model utilizes certain unobservable inputs classified as Level 3 measurements as defined by ASC 820, Fair Value Measurements and Disclosures . Key inputs utilized in the models include a discount rate of 20% and estimated costs to recreate the technology. Based on the valuation model, we determined the fair value of the developed technology to be $10.7 million with an amortization period of 4.0 years.

Our fixed income securities, which are predominantly high-grade corporate bonds, U.S. Treasury bonds, and U.S. Agency bonds, hold similar risk characteristics in that they are traded infrequently, with contractual interest rates and maturity dates. Our certificates of deposit have infrequent secondary market trades and are priced mathematically based on accretion or amortization from purchase date to maturity. Money market funds are actively traded and short-term, and, as a result, the risk for these securities is lower than the risk associated with fixed income securities and certificates of deposit. As a result of our adoption of ASC 326 effective January 1, 2020, we determined that the gross unrealized losses of $0.1 million as of January 1, 2020 were not related to credit losses and, as a result, were recorded in accumulated other comprehensive income (loss) in our condensed consolidated balance sheets. As of June 30, 2020, we had gross unrealized losses of less than $0.1 million with respect to our available-for-sale securities, and we do not intend to sell, nor is it more likely than not that we will be required to sell, these investments before recovery of their amortized cost basis. Credit loss expense related to these unrealized losses was not material to our condensed consolidated statements of operations and comprehensive income (loss) for the six months ended June 30, 2020.

In May and June 2018, we sold $230.0 million aggregate principal amount of our 0.50% Convertible Senior Notes due 2023, or the 2023 Notes, including the initial purchasers’ exercise in full of their option to purchase an additional $30.0 million of the 2023 Notes, in a private offering to qualified institutional buyers pursuant to Rule 144A promulgated under the Securities Act of 1933, as amended, or the Act. The 2023 Notes are our senior, unsecured obligations, and interest is payable semi-annually in arrears on June 1 and December 1 of each year beginning December 1, 2018. In August 2019, we sold $400.0 million aggregate principal amount of our 0.50% Convertible Senior Notes due 2024, or the 2024 Notes, and $400.0 million aggregate principal amount of our 1.00% Convertible Senior Notes due 2026, or the 2026 Notes, including the initial purchasers’ exercise in full of their options to purchase an additional $50.0 million of the 2024 Notes and an additional $50.0 million of the 2026 Notes, in a private offering to qualified institutional buyers pursuant to Rule 144A promulgated under the Act. The 2024 & 2026 Notes are our senior, unsecured obligations, and interest is payable semi-annually in arrears on February 1 and August 1 of each year beginning February 1, 2020. Prior to the close of business on the business day immediately preceding March 1, 2023, or the 2023 Conversion Date, in the case of the 2023 Notes, or May 1, 2024, or the 2024 Conversion Date, in the case of the 2024 Notes, or May 1, 2026, or the 2026 Conversion Date, in the case of the 2026 Notes, the respective Notes are convertible at the option of holders only upon satisfaction of certain conditions and during certain periods, and thereafter, at any time until the close of business on the second scheduled trading day immediately preceding the relevant maturity date. The applicable conversion rate is subject to customary adjustments for certain events as described in the applicable indenture between us and U.S. Bank National Association, as trustee, or, collectively, the Indentures. Upon conversion, the Notes may be settled in shares of our Class A common stock, cash or a combination of cash and shares of our Class A common stock, at our election. It is our current intent to settle the principal amount of the Notes with cash. During the year ended December 31, 2019, a portion of the 2023 Notes were exchanged, as further discussed below. Prior to the close of business on the business day immediately preceding the applicable Conversion Date, the applicable series of Notes is convertible at the option of the holders under the following circumstances: • during any calendar quarter commencing after the calendar quarter subsequent to the calendar quarter in which the applicable series of Notes was issued (and only during such calendar quarter), if the last reported sale price of our Class A common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the applicable conversion price of the applicable series of Notes on each applicable trading day; • during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the applicable series of Notes for each day of that five day consecutive trading day period was less than 98% of the product of the last reported sale price of our Class A common stock and the applicable conversion rate of the applicable series of Notes on such applicable trading day; or • upon the occurrence of specified corporate events described in the applicable Indenture. For at least 20 trading days during the period of 30 consecutive trading days ending June 30, 2020, the last reported sale price of our Class A common stock was greater than or equal to 130% of the conversion price of the 2023 Notes on each applicable trading day. As a result, the 2023 Notes are convertible at the option of the holders during the quarter ending September 30, 2020 and were classified as current liabilities on the condensed consolidated balance sheet as of June 30, 2020. As of the date of this filing, we have not received a material number of requests for conversion. As of June 30, 2020, the if-converted value of the 2023 Notes exceeded its principal amount by $229.3 million. As of June 30, 2020, the 2024 & 2026 Notes were not currently convertible. We may not redeem any series of Notes prior to the relevant maturity date. Holders of any series of Notes have the right to require us to repurchase for cash all or a portion of their applicable series of Notes, at 100% of its respective principal amount, plus any accrued and unpaid interest, upon the occurrence of a fundamental change as defined in the applicable Indenture for such series of Notes. We are also required to increase the conversion rate for holders who convert their Notes in connection with certain corporate events occurring prior to the relevant maturity date. The Notes are our senior unsecured obligations and rank senior in right of payment to any of our indebtedness and other liabilities that are expressly subordinated in right of payment to the Notes, equal in right of payment among all series of Notes and to any other existing and future indebtedness and other liabilities that are not subordinated, effectively junior in right of payment to any of our secured indebtedness and other liabilities to the extent of the value of the assets securing such indebtedness and other liabilities, and structurally junior in right of payment to all of our existing and future indebtedness and other liabilities (including trade payables) of our current or future subsidiaries. Capped Call Transactions In connection with the pricing of the 2023 Notes, we entered into privately negotiated capped call transactions with an affiliate of one of the initial purchasers of the 2023 Notes and other financial institutions. In connection with the pricing of the 2024 & 2026 Notes, we entered into privately negotiated capped call transactions with other financial institutions. The capped call transactions are expected generally to reduce or offset potential dilution to holders of our common stock and/or offset the potential cash payments that we could be required to make in excess of the principal amount upon any conversion of the applicable series of Notes under certain circumstances, with such reduction and/or offset subject to a cap based on the cap price. Under the capped call transactions, we purchased capped call options that in the aggregate relate to the total number of shares of our Class A common stock underlying the applicable series of Notes, with an initial strike price of approximately $44.33 per share in the case of the 2023 Notes, which corresponds to the initial conversion price of the 2023 Notes, and approximately $189.36 per share in the case of the 2024 & 2026 Notes, which corresponds to the initial conversion price of each of the 2024 & 2026 Notes. Further, the capped call options are subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the applicable series of Notes, and have a cap price of $62.22 per share in the case of the 2023 Notes, and $315.60 per share in the case of the 2024 & 2026 Notes. The cost of the purchased capped calls of $19.1 million in the case of the 2023 Notes and $87.4 million in the case of the 2024 & 2026 Notes was recorded as a reduction to additional paid-in-capital. We elected to integrate the applicable capped call options with the applicable series of Notes for federal income tax purposes pursuant to applicable U.S. Treasury Regulations. Accordingly, the $19.1 million gross cost of the purchased capped calls in the case of the 2023 Notes and the $87.4 million gross cost of the purchased capped calls in the case of the 2024 & 2026 Notes will be deductible for income tax purposes as original discount interest over the term of the 2023 Notes and the applicable series of the 2024 & 2026 Notes, respectively. We recorded deferred tax assets of $4.6 million with respect to the 2023 Notes and $20.9 million with respect to the 2024 & 2026 Notes, which represent the tax benefit of these deductions with an offsetting entry to additional paid-in capital. In connection with the exchange agreements discussed below, we terminated a corresponding portion of the existing capped call transactions that we entered into in connection with the issuance of the 2023 Notes, which resulted in the net share settlement and our receipt and retirement of 285,466 shares of Class A common stock. Exchange of 2023 Notes In connection with the issuance of the 2024 & 2026 Notes discussed above, during the year ended December 31, 2019, we entered into exchange agreements with certain holders of our outstanding 2023 Notes and, using a portion of the net proceeds from the issuance of the 2024 & 2026 Notes, we exchanged $145.2 million principal amount, together with accrued and unpaid interest thereon, of the 2023 Notes for aggregate consideration of $145.4 million in cash, representing the principal and accrued interest of the exchanged 2023 Notes, and 2.2 million shares of Class A common stock.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Indemnification In the ordinary course of business, we enter into agreements in which we may agree to indemnify other parties with respect to certain matters, including losses resulting from claims of intellectual property infringement, damages to property or persons, business losses, or other liabilities. In addition, we have entered into indemnification agreements with our directors, executive officers, and certain other employees that will require us to indemnify them against liabilities that may arise by reason of their status or service as directors, officers, or employees. The term of these indemnification agreements with our directors, executive officers, and other employees are generally perpetual after execution of the agreement. The maximum potential amount of future payments we could be required to make under these indemnification provisions is unlimited; however, we maintain insurance that reduces our exposure and enables us to recover a portion of any future amounts paid. As of June 30, 2020 and December 31, 2019, we have not accrued a liability for indemnification provisions we agree to in the ordinary course of business or with our directors, executive officers and certain other employees pursuant to indemnification agreements because the likelihood of incurring a payment obligation, if any, in connection with these arrangements is not probable or reasonably estimable. Litigation From time to time, we may be involved in lawsuits, claims, investigations, and proceedings, consisting of intellectual property, commercial, employment, and other matters, which arise in the ordinary course of business. We are not currently party to any material legal proceedings or claims, nor are we aware of any pending or threatened legal proceedings or claims that could have a material adverse effect on our business, operating results, cash flows, or financial condition should such legal proceedings or claims be resolved unfavorably.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The following table presents details of the provision for (benefit of) income taxes and our effective tax rates (in thousands, except percentages): Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Provision for (benefit of) income taxes $ 12,533 $ (7,320) $ (3,864) $ (17,793) Effective tax rate 55.1 % (69.5) % (7.1) % (117.9) % We account for income taxes according to ASC 740, which, among other things, requires that we estimate our annual effective income tax rate for the full year and apply it to pre-tax income (loss) for each interim period, taking into account year-to-date amounts and projected results for the full year. We periodically evaluate whether we will recover a portion or all of our deferred tax assets. We record a valuation allowance against our deferred tax assets if and to the extent it is more likely than not that we will not recover our deferred tax assets. In evaluating the need for a valuation allowance, we weight all relevant positive and negative evidence, including among other factors, historical financial performance, forecasts of income over the applicable carryforward periods, and our market environment, with each piece weighted based on its reliability. As of June 30, 2020, we had insufficient objective positive evidence that we will generate sufficient future pre-tax income to overcome the negative evidence of cumulative losses. Accordingly, we recorded a full valuation allowance against our U.S. deferred tax assets as of June 30, 2020. Upon establishing the U.S. valuation allowance, we revised our annual effective income tax rate for the year ended December 31, 2020 and recorded the cumulative effect of the revised estimated tax rate through provision for income taxes during the three months ended June 30, 2020. We continue to record a full valuation allowance against our U.K. deferred tax assets as of June 30, 2020. We had a deferred tax liability of $5.6 million as of December 31, 2019, included in other liabilities in our condensed consolidated balance sheets. We account for the tax effects of discrete events in the interim period they occur. The provision for income taxes consists of federal, foreign, state, and local income taxes. Our effective tax rate differs from the statutory U.S. income tax rate due to the effect of state and local income taxes, differing tax rates imposed on income earned in foreign jurisdictions and in the United States, losses in foreign jurisdictions, certain nondeductible expenses, excess tax deductions, and the changes in valuation allowances against our deferred tax assets. Our effective tax rate could change significantly from quarter to quarter because of recurring and nonrecurring factors. The benefit of income taxes for the six months ended June 30, 2020 and 2019 was primarily attributable to discrete tax benefits related to excess tax deductions from settled stock options and RSUs. This was offset by the impact of establishing a valuation allowance against our U.S. deferred tax assets as of June 30,2020. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (CARES) Act, or the CARES Act, was signed into law. The CARES Act includes tax provisions applicable to businesses, such as net operating losses, enhanced interest deductibility, optional deferral of deposits of payroll taxes and a refundable employee retention payroll tax credit. We have determined that these provisions did not have an impact to our condensed consolidated financial statements for the six months ended June 30, 2020. Neither we nor any of our subsidiaries are currently under examination from tax authorities in the jurisdictions in which we do business.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Our unaudited interim condensed consolidated financial statements are presented in accordance with accounting standards generally accepted in the United States of America, or U.S. GAAP, for interim financial information. Certain information and disclosures normally included in consolidated financial statements presented in accordance with U.S. GAAP have been condensed or omitted. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission, or SEC, on February 14, 2020. The unaudited interim condensed consolidated financial statements have been prepared on a basis consistent with that used to prepare the audited annual consolidated financial statements and reflect all adjustments which are, in the opinion of our management, of a normal recurring nature and necessary for a fair statement of the condensed consolidated financial statements. All intercompany accounts and transactions have been eliminated in consolidation. The operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results expected for the full year ending December 31, 2020.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates and assumptions. On an ongoing basis, our management evaluates these estimates and assumptions, including those related to determination of standalone selling prices of our products and services, allowance for doubtful account and sales reserves, income tax valuations, stock-based compensation, goodwill, and intangible assets valuations and recoverability. We base our estimates on historical data and experience, as well as various other factors that our management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities.
Operating Segments	Operating Segments Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the Chief Operating Decision Maker, or CODM, who is our chief executive officer, in deciding how to allocate resources and assess our financial and operational performance. Our CODM evaluates our financial information and resources and assesses the performance of these resources on a consolidated and aggregated basis. As a result, we have determined that our business operates in a single operating segment.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2016-13, Financial Instruments - Credit Losses , or ASC 326. The new standard amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology. As a result, we are now required to use a forward-looking expected credit loss model for accounts receivables and other commitments to extend credit. Through December 31, 2019, we calculated our allowance for credit losses using a single pool of trade receivables as the basis for our credit loss rate. Effective January 1, 2020, we adopted ASC 326 and made changes to our accounting policies related to credit loss calculations, including the consideration of forecasted economic data and the pooling of financial assets with similar risk profiles, and now recognize credit losses associated with our available-for-sale securities. We adopted the new allowance for credit losses accounting standard on January 1, 2020 by means of a cumulative-effect adjustment, where we recognized the cumulative effect of initially applying the guidance as a $0.6 million addition to our contract asset reserve with an offsetting adjustment to retained earnings. See Note 5, Fair Value Measurements and Note 6, Allowance for Doubtful Accounts and Sales Reserves , for additional details. In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract , which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing costs incurred to develop or obtain internal-use software. We adopted this standard prospectively effective January 1, 2020. As a result of the adoption, we are required to capitalize additional costs related to the implementation of cloud computing arrangements that we have historically expensed as incurred, particularly costs incurred during the application development phase. This policy aligns the accounting for implementation costs associated with cloud computing arrangements with our existing policy related to internal-use software. Capitalized costs related to cloud computing arrangements for the six months ended June 30, 2020, which are included in prepaid expenses and other current assets on our condensed consolidated balance sheets, were not material.
Income Taxes	We account for income taxes according to ASC 740, which, among other things, requires that we estimate our annual effective income tax rate for the full year and apply it to pre-tax income (loss) for each interim period, taking into account year-to-date amounts and projected results for the full year. We periodically evaluate whether we will recover a portion or all of our deferred tax assets. We record a valuation allowance against our deferred tax assets if and to the extent it is more likely than not that we will not recover our deferred tax assets. In evaluating the need for a valuation allowance, we weight all relevant positive and negative evidence, including among other factors, historical financial performance, forecasts of income over the applicable carryforward periods, and our market environment, with each piece weighted based on its reliability. As of June 30, 2020, we had insufficient objective positive evidence that we will generate sufficient future pre-tax income to overcome the negative evidence of cumulative losses. Accordingly, we recorded a full valuation allowance against our U.S. deferred tax assets as of June 30, 2020. Upon establishing the U.S. valuation allowance, we revised our annual effective income tax rate for the year ended December 31, 2020 and recorded the cumulative effect of the revised estimated tax rate through provision for income taxes during the three months ended June 30, 2020. We continue to record a full valuation allowance against our U.K. deferred tax assets as of June 30, 2020.
