Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business DoorDash, Inc. (the “Company”), is incorporated in Delaware with headquarters in San Francisco, California. The Company provides a local logistics platform that enables local businesses to address consumers’ expectations of ease and immediacy and thrive in today’s convenience economy. The Company’s local logistics platform connects merchants, consumers, and Dashers. The Company operates the DoorDash Marketplace, which enables merchants to establish an online presence and expand their reach by connecting them with consumers (the “Marketplace”). Merchants can fulfill this demand with independent contractors who use the Company’s platform to deliver orders (“Dashers”). As part of the Marketplace, the Company also offers Pickup, which allows consumers to place advance orders, skip lines, and pick up their orders conveniently with no consumer fees, as well as DoorDash for Work, which provides merchants on the Company’s platform with large group orders and catering orders for businesses and events. The Marketplace also includes DashPass, the Company’s membership product, which was formerly referred to the Company's subscription product, which provides consumers with unlimited access to eligible merchants with zero delivery fees and reduced service fees. In addition to the Marketplace, the Company offers Platform Services, which primarily includes DoorDash Drive, or Drive, a white-label logistics service that enables merchants that have generated consumer demand through their own channels to fulfill this demand using the Company’s local logistics platform, and DoorDash Storefront, or Storefront, that enables merchants to create their own branded online ordering experience, providing them with a turnkey solution to offer consumers on-demand access to e-commerce without investing in in-house engineering or logistics capabilities.

Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of DoorDash, Inc. and its wholly-owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim reporting. All intercompany transactions have been eliminated in consolidation. These unaudited condensed consolidated interim financial statements reflect all normal recurring adjustments that are, in the opinion of management, necessary to fairly present the information set forth herein. They should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. Interim results are not necessarily indicative of the results for a full year. Reclassifications Certain amounts from prior periods have been reclassified to conform to the current period presentation. Use of Estimates The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Estimates include, but are not limited to, revenue recognition, allowances for credit losses, gift card breakage, estimated useful lives of property and equipment, capitalized software and website development costs, intangible assets, stock-based compensation, valuation of investments and other financial instruments, valuation of acquired intangible assets and goodwill, the incremental borrowing rate applied in lease accounting, insurance reserves, loss contingencies, and income and indirect taxes. Actual results could differ from these estimates. Significant Accounting Policies There have been no material changes to the Company's significant accounting policies from its Annual Report on Form 10-K for the fiscal year ended December 31, 2020, except for one policy noted below, which changed as a result of a change in accounting estimates. Gift Cards The Company sells gift cards to consumers that can be redeemed through its Marketplace. Those gift cards have no expiration date and administrative fees are not charged on unused gift cards. In prior periods, with limited history as to consumers' redemption patterns, proceeds from the sale of gift cards were fully deferred and recorded as contract liabilities until consumers use the card to place orders on its platform. When gift cards are redeemed, revenue is recognized on a net basis as the difference between the amounts collected from consumers less amounts remitted to merchants and Dashers. During the third quarter of 2021, the Company concluded that it had developed sufficient historical evidence regarding the pattern of consumer redemptions of gift cards to have the ability to estimate the portion of outstanding gift cards that will never be redeemed (“breakage”) and for which there is no legal obligation to remit the value of the unredeemed gift cards to the relevant jurisdiction as unclaimed or abandoned property. The Company recognizes the breakage amounts as revenue, proportionate to the pattern of revenue recognition for the gift card redemptions. As a result of this change in estimate, the Company recorded $36 million of gift card breakage revenue during the three months ended September 30, 2021. Estimating future breakage rates requires judgment based on current and historical patterns of redemption, and the actual breakage rates may vary from the estimate.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Disaggregated Revenue Information All revenue recognized during the periods presented was related to the Company's core business, which is primarily comprised of Marketplace and Drive. Revenue by geographic area is determined based on the address of the merchant, or in the case of DashPass, the address of the consumer. Revenue by geographic area was as follows (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2020 2021 2020 2021 United States $ 875 $ 1,275 $ 1,912 $ 3,577 International 4 — 4 11 Total revenue $ 879 $ 1,275 $ 1,916 $ 3,588 Contract Liabilities The timing of revenue recognition may differ from the timing of invoicing to or collections from customers. The Company’s contract liabilities balance, which is included in accrued expenses and other current liabilities on the condensed consolidated balance sheets, is primarily comprised of unredeemed gift cards, prepayments received from consumers and merchants, certain consumer credits as well as other transactions for which the revenue is recognized over time. A summary of activities related to contract liabilities for the nine months ended September 30, 2021 was as follows (in millions): Contract Liabilities Beginning balance $ 108 Addition to contract liabilities 815 Reduction of contract liabilities (1)(2)(3) (799) Ending balance $ 124 (1) Gift cards and certain consumer credits can be redeemed through the Company's online Marketplace. When they are redeemed, revenue is recognized on a net basis as the difference between the carrying amount of the gift cards and consumer credits and the amount due to merchants and Dashers for those transactions. Therefore, the amount recognized as revenue related to the reduction of gift cards and certain consumer credits is less than the amount presented in the table above. Net revenues associated with gift cards and certain consumer credits is not tracked by the Company as it is impracticable to do so. (2) Included in the beginning balance of contract liabilities was $22 million associated with unearned prepayments received by the Company, all of which was recognized as revenue during the nine months ended September 30, 2021. (3) During the three months ended September 30, 2021, the Company recorde d $36 million o f gift card breakage revenue, which represented the estimate of cumulative gift card breakage through September 30, 2021 based on the Company's accounting policy discussed in Note 2. Deferred Contract Costs Deferred contract costs represent direct and incremental costs incurred to acquire or fulfill the Company’s contracts, consisting of sales commissions and costs related to merchant onboarding, which the Company expects to recover. Deferred contract costs are amortized on a straight-line basis over the expected period of benefit, which the Company determined by considering historical attrition rates and other factors. Deferred contract costs are recorded in prepaid expenses and other current assets and other assets on the condensed consolidated balance sheets. Amortization of deferred contract costs related to sales commissions is recognized in sales and marketing expense and amortization of deferred contract costs related to merchant onboarding is recognized in cost of revenue, exclusive of depreciation and amortization in the condensed consolidated statements of operations. A summary of activities related to deferred contract costs was as follows (in millions): Nine Months Ended September 30, 2020 2021 Beginning balance $ 21 $ 43 Capitalization of deferred contract costs 21 26 Amortization of deferred contract costs (6) (15) Ending balance $ 36 $ 54 Deferred contract costs, current $ 11 $ 22 Deferred contract costs, non-current 25 32 Total deferred contract costs $ 36 $ 54 Allowance for Credit Losses The allowance for credit losses related to accounts receivable and changes for the nine months ended September 30, 2021 were as follows (in millions): Nine Months Ended September 30, 2021 Beginning balance $ 13 Additions to the provision for expected credit losses 31 Writeoffs charged against the allowance (5) Ending balance $ 39

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings From time to time, the Company may be a party to litigation and subject to claims incidental to its business. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these matters will not have a material adverse effect on its business. Regardless of the outcome, litigation can have an adverse impact on the Company because of judgment, defense and settlement costs, diversion of management resources, and other factors. At each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable, requiring recognition of a loss accrual, or whether the potential loss is reasonably possible, requiring potential disclosure. Legal fees are expensed as incurred. The Company has been and continues to be involved in numerous legal proceedings related to Dasher classification, and such proceedings have increased in volume since the California Supreme Court’s 2018 ruling in Dynamex Operations West, Inc. v. Superior Court (“Dynamex”) . The California Legislature passed legislation (“AB 5”), that was signed into law in September 2019 and became effective on January 1, 2020. AB 5 codified the Dynamex standard regarding contractor classification, expanded its application and created numerous carve-outs, which may have an adverse effect on the Company’s business, financial condition, and results of operations, and may lead to increased legal proceedings and related expenses and may require the Company to significantly alter its existing business model and operations. Further, an increasing number of jurisdictions are considering implementing standards similar to the test set forth in Dynamex to determine worker classification. The Company is currently the subject of regulatory and administrative investigations, audits, and inquiries conducted by federal, state, or local governmental agencies concerning the Company’s business practices, the classification and compensation of delivery providers, the Dasher pay model, and other matters. For example, we are currently under audit by the Employment Development Department, State of California for payroll tax liabilities. The Company believes that Dashers are, and have been, properly classified as independent contractors, and thus plans to vigorously contest any adverse assessment or determination. The Company’s chances of success on the merits is uncertain. In October 2019, the Company made an offer, and in November 2019 it filed a settlement agreement, of $40 million with the representatives of Dashers that had filed actions in the States of California and Massachusetts in order to settle claims under the Private Attorney General Act and class action claims alleging worker misclassification of Dashers against the Company. These actions were filed by and on behalf of Massachusetts Dashers that utilized the DoorDash platform since September 2014 and California Dashers that utilized the DoorDash platform since August 2016. On June 8, 2020, the Company entered into an amended settlement agreement to increase the total amount to be paid by the Company from $40 million to $41 million. In October 2020, the Company entered into an amended settlement agreement to increase the total amount to be paid by the Company from $41 million to $89 million. In April 2021, the Company entered into an amended settlement agreement increasing the total amount to be paid by the Company to $100 million. In March 2020, the Company reached an agreement to resolve worker misclassification claims associated with certain Dashers and Caviar delivery providers who have entered into arbitration agreements with the Company. Under the agreement, certain Dashers and Caviar delivery providers are eligible for settlement payments, subject to a threshold number of the covered individuals entering into individual settlement agreements. The Company anticipated that the aggregate amount of payments to Dashers and Caviar delivery providers under these individual settlement agreements, including attorneys’ fees, would be approximately $70 million. In July 2020, the Company transferred $69 million into an escrow account, the settlement amount to be released and paid to claimants and claimants’ attorneys if a minimum number of claimants agreed to release their claims against the Company by the date specified within the settlement agreement. In December 2020, the number of claimants who agreed to release their claims against the Company exceeded the minimum, and the Company committed to release the settlement amount in the escrow account to claimants and claimants' attorneys. In the nine months ended September 30, 2021, the $69 million in the escrow account was fully distributed to the claimants and claimants' attorneys. In July and August 2020, the Company reached additional agreements to resolve worker misclassification claims associated with certain Dashers and Caviar delivery providers who have entered into arbitration agreements with the Company. Under these agreements, certain Dashers and Caviar delivery providers are eligible for settlement payments, subject to a threshold number of the covered individuals entering into individual settlement agreements. The Company anticipates that the aggregate amount of payments to Dashers and Caviar delivery providers under these individual settlement agreements, including attorneys’ fees, will be approximately $14 million, of which $11 million was paid in the nine months ended September 30, 2021. In June 2020, the San Francisco District Attorney filed an action in the Superior Court of California, County of San Francisco, alleging that the Company misclassified Dashers as independent contractors as opposed to employees in violation of the California Labor Code and the California Unfair Competition Law, among other allegations. This action is seeking both restitutionary damages and a permanent injunction that would bar the Company from continuing to classify Dashers as independent contractors. In August 2020, the San Francisco District Attorney filed a motion for preliminary injunction that would bar the Company from continuing to classify Dashers in California as independent contractors during the pendency of this case. In December 2020, the San Francisco District Attorney withdrew its request for preliminary injunction. It is a reasonable possibility that a loss may be incurred; however, the possible range of losses is not estimable given the status of the case. Indemnification The Company enters into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent, or other intellectual property infringement claim by any third-party with respect to its technology. The terms of these indemnification agreements are generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable because it involves claims that may be made against the Company in the future, but have not yet been made. The Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. The Company has entered into or will enter into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of the individual. No liability associated with such indemnifications was recorded as of December 31, 2020 and September 30, 2021. Bank Commitments and Letters of Credit In November 2019, the Company entered into a revolving credit and guaranty agreement which provides for a $300 million unsecured revolving credit facility maturing on November 19, 2024. Loans under the credit facility bear interest, at the Company’s option, at (i) a base rate equal to the highest of (A) the prime rate, (B) the higher of the federal funds rate or a composite overnight bank borrowing rate plus 0.50%, or (C) an adjusted LIBOR rate for a one-month interest period plus 1.00%, or (ii) an adjusted LIBOR rate plus a margin equal to 1.00%. The Company is also obligated to pay other customary fees for a credit facility of this size and type, including letter of credit fees, an upfront fee, and an unused commitment fee of 0.10%. The credit agreement contains customary affirmative covenants, such as financial statement reporting requirements and restrictions on the use of proceeds, as well as customary negative covenants that restrict its ability and its subsidiaries’ ability to, among other things, incur additional indebtedness, incur liens, declare cash dividends in the entirety or make certain other distributions, merge or consolidate with other companies or sell substantially all of its assets, make investments, loans and acquisitions, and engage in transactions with affiliates. In August 2020, the Company amended and restated its existing revolving credit and guaranty agreement to provide for $100 million of incremental revolving loan commitments, effective upon the consummation of an initial public offering of the Company’s common stock on or prior to August 7, 2021, for total revolving commitments of $400 million. The amendment and restatement also extended the maturity date for the revolving credit facility from November 19, 2024 to August 7, 2025. As of December 31, 2020 and September 30, 2021, the Company was in compliance with the covenants under the credit agreement. As of December 31, 2020 and September 30, 2021, no amounts were drawn and the Company had $44 million and $39 million of issued letters of credit outstanding from the revolving credit and guaranty agreement.

Equity [Abstract]
Common Stock	Common Stock 2014 Equity Incentive Plan In March 2014, the Company adopted the 2014 Stock Option Plan, as amended, or the 2014 Plan, which provided for the granting of stock options to employees, consultants, and advisors of the Company. Options granted under the 2014 Plan are either incentive stock options or nonqualified stock options. Options under the 2014 Plan were granted at prices no less than 100% of the estimated fair value of the shares on the date of grant as determined by the Company’s board of directors; provided, however, that the exercise price of an incentive stock option granted to a greater than 10% stockholder could not be less than 110% of the estimated fair value of the shares on the date of grant. Options granted generally vest over four years. The 2014 Plan allowed for the early exercise of options. Under the terms of the 2014 Plan, option holders, upon early exercise, were required to sign a restricted stock purchase agreement that gave the Company the right to repurchase any unvested shares, at the original exercise price, in the event the grantees’ employment terminated for any reason. The repurchase right lapses over time as the shares vest at the same rate as the original option vesting schedule. Stock-based awards forfeited, cancelled, or repurchased generally were returned to the pool of shares of common stock available for issuance. In connection with the Company's initial public offering (the "IPO"), the 2014 Plan was terminated effective immediately prior to the effectiveness of the 2020 Equity Incentive Plan ("2020 Plan") and the Company ceased granting any additional awards under the 2014 Plan. All outstanding awards under the 2014 Plan at the time of the termination of the 2014 Plan remain subject to the terms of the 2014 Plan, and any shares underlying stock options that expire or terminate or are forfeited or repurchased by the Company under the 2014 Plan were automatically transferred to the 2020 Plan. 2020 Equity Incentive Plan In November 2020, the Company's board of directors adopted, and the Company's stockholders approved, the 2020 Plan, which became effective one business day prior to the effective date of the IPO Registration Statement. The 2020 Plan provides for the granting of nonstatutory stock options, restricted stock, restricted stock units ("RSUs"), stock appreciation rights, performance units, and performance shares for the Company's Class A common stock to the Company's employees, directors, and consultants. Stock-based awards under the 2020 Plan that expire or are forfeited, canceled, or repurchased generally are returned to the pool of shares of Class A common stock available for issuance under the 2020 Plan. In addition, the number of shares of the Company's Class A common stock reserved for issuance under the 2020 Plan will automatically increase on January 1 of each calendar year, starting on January 1, 2021 in an amount equal to the least of (i) 32,493,000 shares, (ii) five percent (5%) of the total number of all classes of common stock outstanding on December 31 of the fiscal year before the date of each automatic increase, or (iii) such other number of shares determined by the Company's board of directors prior to the applicable January 1. The exercise price of the options granted under the 2020 Plan will at least be equal to the fair market value of the Company's Class A common stock on the date of grant. The options may be granted for a term of up to ten years (or five years if the option is an incentive stock option granted to a greater than 10% stockholder) and at prices no less than 100% of the fair market value of the shares on the date of grant, provided, however, that the exercise price of an incentive stock option granted to a greater than 10% stockholder shall not be less than 110% of the estimated fair value of the shares on the date of grant. Options granted under the 2020 Plan generally vest over four years.

In November 2020, the Company’s board of directors approved the grant of 10,379,000 RSUs to the Company's Chief Executive Officer (the “CEO Performance Award”). The CEO Performance Award vests upon the satisfaction of a service condition and achievement of certain stock price goals. As of September 30, 2021, unrecognized stock-based compensation expense related to the CEO Performance Award was $318 million, which is expected to be recognized over a period of 3.57 years. As of September 30, 2021, there was $1.4 billion of unrecognized stock-based compensation expense related to unvested RSUs, excluding the unrecognized stock-based compensation expense associated with the CEO Performance Award granted in November 2020. The Company expects to recognize this expense over the remaining weighted-average period of 2.68 years. 2020 Employee Stock Purchase Plan In November 2020, the Company's board of directors adopted, and the Company's stockholders approved, the 2020 Employee Stock Purchase Plan ("the ESPP"), which became effective on the business day immediately prior to the effectiveness of the registration statement on Form S-1 related to the IPO. A total of 6,498,600 shares of Class A common stock were initially reserved for sale under the ESPP. The number of shares of Class A common stock available for issuance under the ESPP will be increased on the first day of each fiscal year beginning with the fiscal year following the fiscal year in which the first enrollment date (if any) occurs equal to the least of (i) 6,498,600 shares of Class A common stock, (ii) one and one-half percent (1.5%) of the outstanding shares of all classes of common stock on the last day of the immediately preceding fiscal year, or (iii) an amount determined by the administrator of the ESPP.

Income Taxes

Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, the Company updates its estimate of the annual effective tax rate and, if the estimated annual effective tax rate changes, the Company makes a cumulative adjustment in such period. The Company recorded $1 million and zero of provision for income taxes for the three months ended September 30, 2020 and 2021, respectively. The Company recorded $2 million and $3 million of provision for income taxes for the nine months ended September 30, 2020 and 2021, respectively. The provision for income taxes for all the periods presented were primarily attributable to state franchise taxes and income taxes in foreign jurisdictions. The Company regularly assesses the realizability of its deferred tax assets and establishes a valuation allowance if it is more-likely-than-not that some, or all, of its deferred tax assets will not be realized in the future. The Company evaluates and weighs all available evidence, both positive and negative, including its historic operating results, future reversals of existing deferred tax liabilities, as well as projected future taxable income. The Company will continue to regularly assess the realizability of its deferred tax assets. Changes in earnings performance and future earnings projections, among other factors, may cause the Company to adjust the valuation allowance on deferred tax assets, which could materially impact the income tax expense in the period the Company determines that these factors have changed. As of September 30, 2021, the Company continues to maintain a full valuation allowance on its deferred tax assets except in certain foreign jurisdictions. As of September 30, 2021, the Company had $61 million of unrecognized tax benefits, which, if recognized, would result in adjustments to the valuation allowance. The Company is subject to income tax audits in the United States and in foreign jurisdictions. The Company recorded liabilities related to uncertain tax positions and believes that the Company has provided adequate reserves for income tax uncertainties in all open tax years. Due to the Company’s history of tax losses, all years remain open to tax audits.

Earnings Per Share [Abstract]
Net Loss per Share Attributable to Common Stockholders	Net Loss per Share Attributable to Common Stockholders The Company computes net loss per share attributable to common stockholders using the two-class method required for multiple classes of common stock and participating securities. The rights, including the liquidation and dividend rights, of the Class A common stock and Class B common stock are identical, other than voting rights. Accordingly, the Class A common stock and Class B common stock share equally in the Company’s net losses. Before the IPO, the Company’s outstanding securities also included redeemable convertible preferred stock. The holders of redeemable convertible preferred stock did not have a contractual obligation to share in the Company’s losses, and as a result, net losses were not allocated to these securities. The following table sets forth the calculation of basic and diluted net loss per share attributable to common stockholders during the periods presented. RSUs that vested but have not been settled are included in the denominator in calculating net loss per share for the three and nine months ended September 30, 2021 (in millions, except share amounts which are reflected in thousands, and per share data): Three Months Ended September 30, Nine Months Ended September 30, 2020 2021 2020 2021 Common Class A Class B Common Class A Class B Net loss $ (43) $ (92) $ (9) $ (149) $ (284) $ (29) Weighted-average number of shares outstanding used to compute net loss per share, basic and diluted 45,016 308,797 31,372 44,568 302,954 31,323 Net loss per share, basic and diluted $ (0.96) $ (0.30) $ (0.30) $ (3.34) $ (0.94) $ (0.94) The following outstanding shares of potentially dilutive securities were excluded from the computation of diluted net loss per share because including them would have had an anti-dilutive effect, or issuance of such shares is contingent upon the satisfaction of certain performance or market conditions which were not satisfied at the end of the respective periods (in thousands): As of September 30, 2020 2021 Redeemable convertible preferred stock (on an as-converted basis) 239,275 — Stock options to purchase common stock 34,554 21,428 Unvested restricted stock units 20,021 28,103 Convertible promissory notes 5,778 — Total 299,628 49,531

Use of Estimates	Use of EstimatesThe preparation of condensed consolidated financial statements in accordance with GAAP requires management to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Estimates include, but are not limited to, revenue recognition, allowances for credit losses, gift card breakage, estimated useful lives of property and equipment, capitalized software and website development costs, intangible assets, stock-based compensation, valuation of investments and other financial instruments, valuation of acquired intangible assets and goodwill, the incremental borrowing rate applied in lease accounting, insurance reserves, loss contingencies, and income and indirect taxes. Actual results could differ from these estimates.
Gift Cards, Contract Liabilities and Deferred Contract Costs	Gift Cards The Company sells gift cards to consumers that can be redeemed through its Marketplace. Those gift cards have no expiration date and administrative fees are not charged on unused gift cards. In prior periods, with limited history as to consumers' redemption patterns, proceeds from the sale of gift cards were fully deferred and recorded as contract liabilities until consumers use the card to place orders on its platform. When gift cards are redeemed, revenue is recognized on a net basis as the difference between the amounts collected from consumers less amounts remitted to merchants and Dashers. During the third quarter of 2021, the Company concluded that it had developed sufficient historical evidence regarding the pattern of consumer redemptions of gift cards to have the ability to estimate the portion of outstanding gift cards that will never be redeemed (“breakage”) and for which there is no legal obligation to remit the value of the unredeemed gift cards to the relevant jurisdiction as unclaimed or abandoned property. The Company recognizes the breakage amounts as revenue, proportionate to the pattern of revenue recognition for the gift card redemptions. As a result of this change in estimate, the Company recorded $36 million of gift card breakage revenue during the three months ended September 30, 2021. Estimating future breakage rates requires judgment based on current and historical patterns of redemption, and the actual breakage rates may vary from the estimate.
Fair Value	The fair value of the Company’s Level 1 financial instruments is based on quoted market prices for identical instruments in active markets. The fair value of the Company’s Level 2 fixed income securities is obtained from an independent pricing service, which may use quoted market prices for identical or comparable instruments in less active markets or model driven valuations using observable market data or inputs corroborated by observable market data.

Net revenues associated with gift cards and certain consumer credits is not tracked by the Company as it is impracticable to do so.
