Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and description of business	1. Organization and description of business Description of business Udemy, Inc. (“Udemy” or the “Company”) was incorporated in January 2010 under the laws of the state of Delaware. The Company is headquartered in San Francisco, California. Udemy is a global marketplace platform for teaching and learning, connecting millions of learners to the skills they need to succeed. The Company’s platform allows learners all over the world to access affordable and relevant content from expert instructors. Udemy combines high-quality content, insights and analytics, and technology into a single, unified platform that is purpose-built to meet the specific needs of both individual learners and enterprise customers. Initial public offering On October 29, 2021, the Company completed its initial public offering ("IPO") of common stock, in which it sold 14,500,000 shares. The shares were sold at a price to the public of $29.00 per share for net proceeds of $397.4 million, after deducting underwriting discounts and commissions of $23.1 million. Underwriters were granted an option for a period of 30 days to purchase up to 2,175,000 additional shares of common stock. Upon the completion of the IPO, deferred offering costs of $6.8 million were reclassified into additional paid-in capital as a reduction of the net proceeds received from the IPO. Upon the closing of the IPO, all outstanding shares of the Company’s redeemable convertible preferred stock automatically converted into 85,403,933 shares of common stock on a one-for-one basis. On November 24, 2021, the underwriters exercised the right to purchase 650,000 additional shares of common stock from the Company, resulting in additional net proceeds of $17.8 million, after deducting underwriting discounts and commissions of $1.0 million. The remaining option to purchase additional shares expired unexercised at the end of the 30 day period.

Accounting Policies [Abstract]
Summary of significant accounting policies	2. Summary of significant accounting policies Basis of consolidation and presentation —The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation, and all other normal and recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results of the periods presented have been made. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which was originally filed with the SEC on March 25, 2022. Segment information —The Company defines its segments as those operations the chief operating decision maker (“CODM”), determined to be the Chief Executive Officer of the Company, regularly reviews to allocate resources and assess performance. For the three and six months ended June 30, 2022 and 2021, the Company operated under two operating and reportable segments: Consumer and Enterprise. The Company continually monitors and reviews its segment reporting structure in accordance with Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting, to determine whether any changes have occurred that would impact its reportable segments. For further information on the Com pany’s segment reporting, see Note 16 – Segment and geographic information. Use of estimates —The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the condensed consolidated financial statements and the results of operations during the reporting periods. Significant estimates and assumptions reflected in the condensed consolidated financial statements include, but are not limited to, allowance for doubtful accounts, useful lives of property and equipment, capitalization of internally developed software and associated useful lives, the carrying value of operating lease right-of-use assets, stock-based compensation, determination of the income tax valuation allowance and the potential outcome of uncertain tax positions, estimated instructor withholding tax obligations, estimated period of consumption for consumer learners’ single course purchases, the period of benefit for deferred commissions, the fair value and associated useful lives of intangible assets and goodwill acquired via business combinations, and the valuation of privately-held strategic investments, including impairments. Management periodically evaluates such estimates and assumptions for continued reasonableness. Actual results may ultimately differ from management’s estimates and such differences could be material to the financial position and results of operations. Coronavirus disease 2019 (“COVID-19”) —In March 2020, the World Health Organization declared the outbreak of the coronavirus disease named COVID-19 a pandemic. The COVID-19 pandemic has created and may continue to create significant uncertainty in global financial markets. This uncertainty may positively or adversely impact certain aspects of the business, including but not limited to customer demand and spending, the ability to raise capital, impairment of assets, and cash collections. While the Company has not experienced a material negative impact to its business, results of operations, financial position, and liquidity, the future duration, impact, and disruption of the COVID-19 outbreak to the Company’s operations is uncertain. Concentration of credit risk —Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, and accounts receivable. For cash, cash equivalents, and restricted cash, the Company is exposed to credit risk in the event of default by the financial institutions to the extent the amounts recorded on the accompanying condensed consolidated balance sheets are in excess of federal insurance limits. The Company generally does not require collateral or other security in support of accounts receivable. To reduce credit risk, management performs ongoing evaluations of its customers’ financial condition. The Company analyzes the need for reserves for potential credit losses and records allowances for doubtful accounts when necessary . No customer accounted for more than 10% of total accounts receivable as of June 30, 2022, or December 31, 2021. No customer accounted for more than 10% of total revenue during the three and six months ended June 30, 2022 and 2021. Summary of significant accounting policies —Except as described below, there were no significant changes to the Company’s significant accounting policies disclosed in Note 2 – Summary of significant accounting policies of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which was originally filed with the SEC on March 25, 2022 . Restricted cash —Restricted cash primarily consists of cash restricted in connection with lease agreements for the Company’s facilities. Restricted cash is included in current assets for leases that expire within one year from the balance sheet date and in non-current assets for leases that expire in more than one year from the balance sheet date. June 30, December 31, Reconciliation of cash, cash equivalents and restricted cash 2022 2021 Cash and cash equivalents $ 512,166 $ 533,868 Restricted cash, non-current 3,629 2,900 Total cash, cash equivalents and restricted cash $ 515,795 $ 536,768 Accounts receivable and allowance for doubtful accounts— Accounts receivable primarily represent amounts owed to the Company for Enterprise subscriptions. Also included in accounts receivable are amounts due from payment processors or mobile application store partners that settle over a period longer than five business days. Accounts receivable balances are recorded at the invoiced amount and are non-interest-bearing. Accounts receivable are presented net of allowances for doubtful accounts. Management assesses the Company’s ability to collect outstanding receivables and records allowances when collection becomes doubtful. The provision for bad debt is recorded in general and administrative expenses in the accompanying condensed consolidated statements of operations. These estimates are based on the assessment of the credit worthiness of the Company’s customers based on multiple sources of information and analysis of such factors as the Company’s historical collection experience and industry and geographic concentrations of credit risk. Accounts receivable deemed to be uncollectible are written off, net of any amounts that may be collected. Balance at Beginning of Period Charged to Expenses Charges Utilized/Written-off Balance at End of Period Allowance for doubtful accounts Six months ended June 30, 2022 $ 678 $ 517 $ (117) $ 1,078 Six months ended June 30, 2021 $ 643 $ 170 $ (310) $ 503 Fair value of financial instruments— The Company considers fair value as the exchange price that would be received for an asset or paid to transfer a liability, an exit price, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Valuation techniques used to measure fair value are either observable or unobservable. Observable inputs reflect assumptions that market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity’s pricing based on their own market assumptions. The Company utilizes the following three-level fair value hierarchy to establish the priorities of the inputs used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Inputs are observable, unadjusted quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data; and Level 3—Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable. The carrying amounts of cash, cash equivalents, restricted cash, and accounts receivable, as well as accounts payable, approximate fair value due to the relatively short-term maturities and are classified as short-term assets and liabilities, respectively, in the accompanying condensed consolidated balance sheets. The fair value of assets that are measured at fair value on a recurring basis are as follows (in thousands): Fair Value Hierarchy Level 1 Level 2 Level 3 June 30, 2022 Strategic investments $ — $ — $ 15,000 Total as of June 30, 2022 $ — $ — $ 15,000 December 31, 2021 Strategic investments $ — $ — $ 10,000 Total as of December 31, 2021 $ — $ — $ 10,000 The fair value of liabilities that are measured at fair value on a recurring basis are as follows (in thousands): Fair Value Hierarchy Level 1 Level 2 Level 3 June 30, 2022 Cash settled stock appreciation rights $ — $ — $ 419 Total as of June 30, 2022 $ — $ — $ 419 December 31, 2021 Cash settled stock appreciation rights $ — $ — $ 818 Total as of December 31, 2021 $ — $ — $ 818 During the six months ended June 30, 2021, the remaining outstanding 12,595 warrants to purchase Series A-1 redeemable convertible preferred stock were exercised for an immaterial amount of cash proceeds at an exercise price of $0.196 per share. The Company reclassified the $0.2 million fair value of the warrants into Series A-1 redeemable convertible preferred stock on the condensed consolidated balance sheet. The change in fair value of the warrants during six months ended June 30, 2021 was immaterial. A summary of the changes in the fair value of Level 3 financial instruments, of which remeasurement of stock appreciation rights are recognized in the condensed consolidated statements of operations, is as follows (in thousands): Warrants Stock Appreciation Rights Strategic Investments Balance— March 31, 2022 $ — $ 508 $ 15,000 Vesting and remeasurement of stock appreciation rights, net of exercises — (89) — Balance— June 30, 2022 $ — $ 419 $ 15,000 Balance— March 31, 2021 $ — $ 674 $ — Vesting and remeasurement of stock appreciation rights — 117 — Balance— June 30, 2021 $ — $ 791 $ — Balance— December 31, 2021 $ — $ 818 $ 10,000 Vesting and remeasurement of stock appreciation rights, net of exercises — (399) — Purchases of strategic investments — — 5,000 Balance— June 30, 2022 $ — $ 419 $ 15,000 Balance— December 31, 2020 $ 160 $ 268 $ — Exercise of redeemable convertible preferred stock warrants (160) — — Vesting and remeasurement of stock appreciation rights — 523 — Balance— June 30, 2021 $ — $ 791 $ — Operating leases— The Company leases real estate facilities under non-cancelable operating leases with various expiration dates through fiscal year 2026. The Company determines if an arrangement contains a lease at inception based on whether there is an identified tangible asset and whether the Company controls the use of the identified asset throughout the period of use. The Company adopted Accounting Standard Update (“ASU”) No. 2016-02, Leases (Topic 842) on January 1, 2022. Operating leases are included in operating lease right-of-use (“ROU”) assets and in operating lease liabilities in the accompanying condensed consolidated balance sheet. Operating lease ROU assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The Company measures its operating lease liabilities at lease inception date based on the present value of total lease payments over the lease term. Total lease payments are discounted to present value using the more readily determinable of (i) the rate implicit in the lease or (ii) the Company’s incremental borrowing rate (which is the estimated rate the Company would be required to pay for a collateralized borrowing equal to the total lease payments over the term of the lease). Because the Company’s operating leases generally do not provide an implicit rate, the Company estimates its incremental borrowing rate using information available at the lease commencement date, including but not limited to credit rating, lease term, and the currency in which the arrangement is denominated. The Company’s operating lease ROU assets are equal to the corresponding operating lease liability, adjusted for payments made to the lessor at or before the commencement date, initial direct costs incurred, and tenant incentives under the lease. The Company does not assume renewals or early terminations unless it is reasonably certain to exercise these options at commencement. The Company does not allocate consideration between lease and non-lease components. Variable lease payments, such as those for common area maintenance or property taxes, are not included in the measurement of operating lease liabilities and are expensed as incurred. In addition, the Company does not recognize operating ROU assets or operating lease liabilities for leases with a term of 12 months or less for all asset classes. Operating lease expense is recognized on a straight-line basis over the lease term. Lease accounting prior to the adoption of Topic 842 The Company recorded total rent expense on a straight-line basis over the lease term consistent with Topic 840. The Company recorded the difference between cash rent payments and straight-line rent expense, generally due to rent escalations and tenant improvement allowances, as a deferred rent liability within accrued expenses and other current liabilities and other liabilities, non-current, each of which were immaterial as of December 31, 2021. Recently Adopted Accounting Pronouncements —In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted the standard with an effective date of January 1, 2021 using the prospective transition adoption approach. Capitalized implementation costs are recorded in prepaid expenses and other current assets and other assets in the condensed consolidated balance sheet. The adoption of this ASU did not have a material impact on the condensed consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires a lessee to record an asset representing the lessees’ right to use the underlying asset and a liability to make lease payments. At inception, lessees must classify all leases as either finance or operating based on five criteria. Balance sheet recognition of finance and operating leases is similar, but the pattern of expense recognition in the income statement, as well as the effect on the statement of cash flows, differs depending on the lease classification. The Company adopted Topic 842 on January 1, 2022, using the modified retrospective approach. The Company elected the package of practical expedients, the use of hindsight in determining the lease term, and the practical expedient to not recognize an operating ROU asset or operating lease liability for leases with a term of 12 months or less. Upon adoption, the Company recognized $17.6 million in operating ROU assets and $20.0 million in operating lease liabilities in its condensed consolidated balance sheets. The difference between the amounts of operating ROU assets and operating lease liabilities consisted of deferred rent and prepaid rent that were derecognized upon transition. There was no adoption date impact to accumulated deficit, and adoption of the new standard did not have a material impact on the Company’s condensed consolidated statements of operations or cash flows. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which aims to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to (1) recognition of an acquired contract liability and (2) payment terms and their effect on subsequent revenue recognized by the acquirer. The Company elected to early adopt this standard on a prospective basis on January 1, 2022. There has been no impact of adoption to date, as the Company has not entered into any business combinations since adoption. The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, EGCs can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, the condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. Based on the market value of its common stock held by non-affiliates as of the last business day of the second fiscal quarter ended June 30, 2022, the Company will cease to be an EGC on December 31, 2022. New accounting pronouncements not yet adopted —In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. The FASB issued ASU 2019-10 in November 2019, which deferred the effective date for nonpublic entities, including EGCs, that had not yet adopted the original ASU. The Company will meet the criteria to become a large accelerated filer as of December 31, 2022, upon which time the ASU will become effective for the fiscal year ending on December 31, 2022. The Company is currently assessing the potential impact of the new standard on the Company’s condensed consolidated financial statements. In December 31, 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles of income taxes and reducing the cost and complexity in accounting for income taxes. The ASU is effective for the Company’s fiscal year beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company is currently assessing the potential impact of the new standard on the Company’s condensed consolidated financial statements.

Investments, All Other Investments [Abstract]
Strategic investments	6. Strategic investments In the fiscal year ended December 31, 2021, the Company made a strategic investment of $10.0 million in cash for preferred shares of privately held online education platform technology company. On February 28, 2022, the Company completed the second tranche purchase of this investment, which resulted in an incremental cash investment of $5.0 million, for a total value of $15.0 million. The estimation of fair value for this investment requires the use of significant unobservable inputs, and as a result, the Company classifies this investment as Level 3 within the fair value hierarchy. The carrying value of this investment is adjusted based on price changes from observable transactions of identical or similar securities of the same issuer (referred to as the measurement alternative) or for impairment. Any changes in carrying value are recorded within other expense, net in the condensed consolidated statements of operations. As of June 30, 2022, there have been no observable transactions that would cause the Company to adjust the carrying amount of the investment, resulting in no realized or unrealized gains or losses for the three and six months ended June 30, 2022. The Company evaluates this investment for impairment at each reporting period. This evaluation consists of several potential qualitative and quantitative impairment indicators including, but not limited to, the investee's financial metrics, whether there were any significant adverse changes in the economic environment or general market conditions of the geographies and industries in which the investee operates, and any other publicly available information that may affect the value of the investment. Based on the assessment performed as of June 30, 2022, the Company did not recognize any impairment losses during the three and six months ended June 30, 2022. The Company did not own any strategic investments during the three and six months ended June 30, 2021.

Business Combination and Asset Acquisition [Abstract]
Business combinations	7. Business combinations On August 24, 2021, the Company completed its acquisition of CorpU, an online learning platform and content catalog focused on blended executive training. The acquisition is intended to deepen the Company’s UB offerings through CorpU’s cohort-based learning in scalable, virtual environments. The transaction has been accounted for as a business combination. The purchase price was $28.6 million, of which $27.1 million was paid at closing with the remaining balance recorded in the accrued expenses and other current liabilities caption of the accompanying condensed consolidated balance sheets. The remaining balance is expected to be paid in August 2022 after adjustment for any indemnification losses incurred by the Company for which it is entitled to recover. The Company issued 61,300 shares of restricted common stock to a former executive of CorpU, which is not included in the calculation of the acquisition purchase price and is accounted for as post-acquisition stock-based compensation over a three-year term. The total purchase consideration of the CorpU acquisition was allocated to the tangible and intangible assets acquired, and liabilities assumed, based upon their respective fair values as of the date of the acquisition. Management determined the preliminary fair values based on a number of factors, including a valuation from an independent third-party valuation firm. The excess of the purchase price over the net assets acquired was recorded as goodwill. Goodwill is attributable t o the assembled workforce and anticipated synergies arising from the acquisition, and has been allocated to the Enterprise reporting segment for the purposes of annual impairment testing. The goodwill recorded in the acquisition is not expected to be deductible for income tax purposes. The assets acquired and liabilities assumed were recorded at fair value as follows (in thousands): Cash and cash equivalents $ 2,641 Accounts receivable, net 250 Prepaid expenses and other current assets 67 Property and equipment, net 133 Intangible assets 15,100 Goodwill 12,646 Accounts payable and other liabilities (596) Deferred revenue (1,610) Total acquisition consideration $ 28,631 The Company has included the financial results of CorpU in the condensed consolidated financial statements from the date of acquisition, which for the three and six months ended June 30, 2022, were not material. The business combination does not qualify as an acquisition of a significant business, and therefore pro forma financial statements were not required.

Indirect tax payables also include withholding taxes on payments made to the Company’s instructors before remitting these amounts to the taxing authorities. Indirect tax reserves primarily relate to instructor withholding tax reserves. Instructor withholding tax reserves —The Company conducts operations in many tax jurisdictions throughout the United States and the rest of the world. The Company has an obligation to comply with information reporting and tax withholding requirements with regards to certain payments made to its U.S. and non-U.S. instructors. Under United States federal tax rules, in the case where the Company withholds less than the correct amount of tax or fails to report it, it is liable for the correct amount that it was required to withhold, plus interest and potential penalties. The Company may be entitled to relief on certain payments if the Company can obtain documentation (e.g. taxpayer identification forms) from instructors establishing that the instructor payee qualifies for reduced withholding tax rates, or that the instructor payee reported the payments and paid the corresponding taxes owed. Prior to March 2020, the Company had not obtained appropriate taxpayer identification forms from instructors, nor remitted applicable tax withholding amounts to the U.S. Internal Revenue Service (“IRS”) where required. In accordance with GAAP, the Company recorded a provision for its tax exposure when it was both probable that a liability had been incurred and the amount of the exposure could be reasonably estimated. Given the significant quantity of instructor payments the Company makes in its operations, the Company has applied a statistical sampling approach that is analogous to methods commonly used by the IRS when determining the extent of withholding tax obligations during IRS audits for the historical instructor payments. The instructor withholding provision estimate includes several key assumptions including, but not limited to, the tax characterization of the Company’s payments made to instructors, the historical lookback practices and scoping precedents of the IRS, the methods for sourcing of instructor payments to U.S. and non-U.S. jurisdictions, and management’s estimate of the penalty relief on certain instructor payments it will be entitled to. Beginning in March 2020, the Company began collecting appropriate taxpayer identification forms from its instructors, assessing whether the forms justified a reduced rate of withholding or withholding exemption, and remitting withholding tax payments to the IRS where required. The Company also began reporting payments to its non-U.S. instructors and the IRS annually where required to do so. As of June 30, 2022, the Company determined that it was probable that it would owe an estimated $15.9 million for withholding taxes related to historical payments to its instructors. The Company has recorded this amount in accrued expenses and other liabilities in the accompanying condensed consolidated balance sheets. Changes in the estimated amount the Company has determined it will owe are recorded in general and administrative expenses in the accompanying condensed consolidated statements of operations. Estimated interest is recorded in interest income (expense), net in the accompanying condensed consolidated statement of operations. Changes to the instructor withholding tax reserve are as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Balance, beginning of period $ 15,693 $ 22,334 $ 17,036 $ 22,166 Amounts charged to (released from) expense 157 200 (1,186) 368 Net payments and settlements — — — — Balance, end of period $ 15,850 $ 22,534 $ 15,850 $ 22,534 In 2020, the Company approached the IRS to address the historical tax withholding amounts for instructors. Final settlement of the matter could differ materially from the estimate recorded in the accompanying condensed consolidated balance sheets, and there exists a reasonable possibility that the Company could incur losses that are significantly more or significantly less than the Company has accrued as of June 30, 2022 and December 31, 2021. As of June 30, 2022, the Company estimated $15.9 million as its best estimate of the potential loss.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	10. Commitments and contingencies Noncancellable purchase commitments —The Company has contractual commitments with its cloud infrastructure provider, network service providers and paid advertising vendors that are noncancellable. As of June 30, 2022, the Company had ap proximately $18.8 million worth of future minimum payments under the Company’s noncancellable purchase commitments which are expected to be paid through 2024. Indemnification —The Company enters into indemnification provisions under agreements with other parties in the ordinary course of business, including certain business partners, investors, contractors, and the Company’s officers, directors, and certain employees. The Company has agreed to indemnify and defend the indemnified party’s claims and related losses suffered or incurred by the indemnified party resulting from actual or threatened third-party claims because of the Company’s activities or, in some cases, non-compliance with certain representations and warranties made by the Company. In general, the Company does not record any liability for these indemnities in the accompanying condensed consolidated balance sheets as the amounts cannot be reasonably estimated and are not considered probable. The Company does, however, accrue for losses for any known contingent liability, including those that may arise from indemnification provisions, when future payment is probable. To date, losses recorded in the Company’s condensed consolidated statements of operations in connection with the indemnification provisions have not been material. Litigation —From time to time, in the ordinary course of business, the Company is subject to legal proceedings, claims, investigations, and other proceedings, including claims of alleged infringement of third-party patents and other intellectual property rights, and commercial, employment, and other matters. In accordance with generally accepted accounting principles, the Company makes a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least annually and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. The outcome of such litigation is not expected to have a material effect on the financial position, results of operation and cash flows of the Company. The Company has recorded an immaterial amount related to all outstanding litigation matters as of June 30, 2022.

Income taxes

Income Tax Disclosure [Abstract]
Income taxes	11. Income taxes The provision for income taxes for interim periods is determined using an estimate of the Company’s annual effective tax rate, adjusted for discrete items, if any, that are taken into consideration in the relevant period. Each quarter, the Company updates the estimate of the annual effective tax rate, and if the estimated tax rate changes, the Company records a cumulative adjustment to the provision. The income tax provision resulted in an effective tax rate for the three months ended June 30, 2022 and 2021, of (1.1)% and (1.4)%, respectively, and (1.2)% and (3.7)% for the six months ended June 30, 2022 and 2021, respectively. During the three and six months ended June 30, 2022, as compared to the same periods in the prior year, the effective tax rate decreased primarily due to changes in foreign tax expense and foreign withholding taxes. The difference between the 21% statutory federal tax rate and the effective tax rate was primarily a result of income earned in jurisdictions with higher statutory tax rates, foreign withholding taxes, and tax credits offset by change in valuation allowance. As of June 30, 2022 and December 31, 2021, the Company has provided a valuation allowance against U.S. federal and state deferred tax assets. Management continues to evaluate the realizability of deferred tax assets and the related valuation allowance. If management's assessment of the deferred tax assets or the corresponding valuation allowance were to change, the Company would record the related adjustment to income during the period in which management makes the determination. The Company recognizes interest and penalties associated with uncertain tax benefits as part of the income tax provision. To date, the Company has not recognized any interest and penalties in its condensed consolidated statements of operations, nor has it accrued for or made payments for interest and penalties. The Company is subject to taxation in the U.S. and various foreign jurisdictions. Due to NOL carryforwards and tax credit carryforwards, the statutes of limitations remain open for tax years from inception of the Company through 2021. There are currently no income tax audits underway by U.S. federal or state taxing authorities.

Retirement Benefits [Abstract]
Employee retirement plan	12. Employee retirement plan The Company maintains a 401(k) retirement savings plan covering eligible employees.

Stockholders' equity	14. Stockholders' equity Preferred stock— In connection with the IPO, the Company’s amended and restated certificate of incorporation became effective, which authorized the issuance of 50,000,000 shares of undesignated preferred stock with a par value of $0.00001 per share with rights and preferences, including voting rights, designated from time to time by the board of directors. Common stock— Common stockholders are entitled to one vote per share. The Company had the following common stock reserved for future issuance as of June 30, 2022, and December 31, 2021, respectively: June 30, December 31, 2022 2021 Stock options to purchase common stock (1) 18,553,783 20,342,259 Shares available for future issuance under: 2021 Equity Incentive Plan 6,831,278 11,417,359 2021 Employee Stock Purchase Plan 2,273,246 2,800,000 Total shares of common stock reserved 27,658,307 34,559,618 (1) Excludes 104,880 and 106,155 cash-settled stock appreciation rights (“SARs”) outstanding as of June 30, 2022, and December 31, 2021, respectively. Equity incentive plans— In 2010, the Company adopted the 2010 Equity Incentive Plan (the “2010 Plan”). The 2010 Plan provided for incentive stock options (“ISOs”), non-statutory stock options (“NSOs”, collectively with ISOs, “stock options”), SARs, restricted stock, and restricted stock units (“RSUs”) to be granted to eligible employees, directors, and consultants. The 2010 Plan was terminated in October 2021 in connection with the IPO but continues to govern the terms and conditions of the outstanding awards granted pursuant to the 2010 Plan. No further equity awards will be granted under the 2010 Plan. The Company adopted the 2021 Equity Incentive Plan (the "2021 Plan") in September 2021, which became effective on October 28, 2021 (collectively with the 2010 Plan, the “Equity Incentive Plans”) and was approved by the Company’s stockholders. The 2021 Plan provides for the granting of ISOs, NSOs, SARs, restricted stock, RSUs, and performance awards to eligible employees, directors, and consultants. The Company initially reserved 13,800,000 shares for issuance under the 2021 Plan. The amount available for issuance is subject to an annual increase on the first day of each calendar year, beginning on January 1, 2023, in an amount equal to 5% of the outstanding shares of the Company’s common stock on the last day of the immediately preceding calendar year or a lesser amount determined by the Company’s Board of Directors or compensation committee. The amount available for issuance shall also include Returning Shares, which are any shares subject to awards granted under the 2010 Plan that, on or after October 29, 2021, expire or otherwise terminate without having been exercised in full, are tendered to or withheld by the Company for payment of an exercise price or for tax withholding obligations, or are forfeited to or repurchased by the Company due to failure to vest. Stock options —The Company may grant stock options at exercise prices not less than the fair market value at the date of grant. These options generally expire 10 years from the date of grant. The Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period for each award, which is generally even over four years. The following is a summary of activity for stock options under the Equity Incentive Plans (amounts in thousands, except share and per share amounts): Options Outstanding Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Balance - December 31, 2021 19,942,259 $ 9.70 8.14 $ 226,350 Granted — — Exercised (846,284) 4.30 Canceled (942,192) 13.80 Balance - June 30, 2022 18,153,783 $ 9.74 7.45 $ 67,812 Vested & expected to vest as of June 30, 2022 18,153,783 $ 9.74 7.45 $ 67,812 Exercisable as of June 30, 2022 10,042,942 $ 6.00 6.90 $ 50,941 There were no stock options granted during the six months ended June 30, 2022. Total aggregate intrinsic value of options exercised during the six months ended June 30, 2022 and 2021, was $7.6 million and $34.9 million, respectively. As of June 30, 2022, total unrecognized stock-based compensation expense related to unvested stock options was $72.8 million, which will be recognized over a weighted average period of 2.1 years. Stock appreciation rights— The Company may grant SARs at exercise prices not less than the fair market value at the date of grant. The SARs are liability-classified awards that generally expire 10 years from the date of grant. The Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period for each award, which is generally even over four years. The following is a summary of activity for SARs under the Equity Incentive Plans (amounts in thousands, except share and per share amounts): SARs Outstanding Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Balance - December 31, 2021 106,155 $ 8.45 8.25 $ 1,267 Granted — — Exercised (743) 3.63 Canceled (532) 10.02 Balance - June 30, 2022 104,880 $ 8.48 7.76 $ 392 Vested & expected to vest as of June 30, 2022 104,880 $ 8.48 7.76 $ 392 Exercisable as of June 30, 2022 63,358 $ 6.49 7.53 $ 283 There were no SARs granted during the six months ended June 30, 2022. As of June 30, 2022, total compensation cost related to unvested SARs not yet recognized was $0.2 million, which will be recognized over a weighted average period of 1.9 years. Restricted stock units— The Company first issued RSU awards in the fiscal year ended December 31, 2021. The fair value of RSUs is determined using the fair value of the Company’s common stock on the date of grant. The Company recognizes stock-based compensation expense for RSUs with service-based vesting conditions on a straight-line basis over the requisite service period for each award, which typically vest over a three A summary of RSU activity under the 2021 Plan is as follows: RSUs Outstanding Weighted Average Grant Date Fair Value Unvested - December 31, 2021 2,545,051 $ 27.64 Granted 6,033,535 $ 12.79 Released (85,226) $ 24.30 Canceled (505,242) $ 19.15 Unvested - June 30, 2022 7,988,118 $ 17.00 As of June 30, 2022, total unrecognized stock-based compensation expense related to unvested RSUs was $121.7 million, which will be recognized over a weighted average period of 3.6 years. Performance-based awards— U nder the Equity Incentive Plans, the Company may grant share-based awards whose vesting is contingent on meeting various departmental or company-wide performance goals, such as the achievement of certain sales targets or an IPO event, in lieu of or in addition to a service-based vesting condition (“Performance-Based Awards”). Such awards are generally granted with an exercise price equal to the fair market value of the underlying common stock share on the date of grant and have a contractual term of 10 years. If vesting is dependent on satisfying a performance condition that is probable of being achieved, the Company estimates the expected term as the midpoint between the time at which the performance conditions are probable of being satisfied and the contractual term of the award. If vesting is dependent on satisfying a performance condition that is not probable of being achieved and the service period is not explicitly stated, the Company estimates the expected term as the contractual term. The remaining inputs to the Black-Scholes option pricing model used to determine grant date fair value, including risk-free interest, expected volatility, and expected dividend yield, are calculated using the same method as that used for stock options with service-based vesting conditions. Grants for Performance-Based Awards are made out of the same pool of stock options available for future issuance under the Equity Incentive Plans. Compensation expense for Performance-Based Awards is based on the grant date fair market value. The Company recognizes expense for Performance-Based Awards having either (a) multiple performance-based vesting conditions, or (b) performance and graded service-based vesting conditions, by separately attributing each vesting tranche of the award over the requisite service period applicable to each vesting condition. Management’s estimate of the number of shares expected to vest is based on the anticipated achievement of the specified performance goals. If the performance-based vesting condition is considered probable of being achieved, the Company recognizes expense over the remaining service period based on the probable outcome of achievement. If the performance goals are not met, no compensation cost is recognized, and any previously recognized compensation cost is reversed. For awards with both performance and service-based vesting conditions where the performance condition is considered improbable of being achieved, the Company does not recognize expense until the performance condition is satisfied, after which time expense is recognized over the requisite service period. The Company had two Performance-Based Awards outstanding as of June 30, 2022, and December 31, 2021. In 2018, the Company granted an award of 50,000 stock options that was eligible to vest upon the closing of the Company’s IPO occurring prior to the sixth (6th) anniversary of the date the award was granted and subject to recipient’s continued service to the Company. Upon the completion of the IPO requirement, the options vest in 48 equal monthly installments thereafter, subject to the recipient continuing to provide service to the Company through each vesting date. Prior to the Company’s IPO on October, 29, 2021, management considered the performance-based vesting conditions improbable of being satisfied. Upon completion of the IPO, the performance condition was satisfied, and the Company recognized an immaterial amount of cumulative stock-based compensation expense. In 2020, the Company granted 350,000 stock options with performance-based vesting conditions, with 50% vesting when the Company achieves $230.0 million in UB Annual Recurring Revenue (“ARR”), and the other 50% vesting when the Company achieves $330.0 million in UB ARR. Management considered that both performance-based vesting conditions were probable of being satisfied during the performance period. As such, the Company began recognizing expense for each tranche of the award using the estimated time period by which the performance conditions are probable of being achieved. The $230.0 million UB ARR performance condition was achieved in the fourth quarter of fiscal year 2021, and the Board of Directors’ compensation committee formally certified satisfaction of the performance condition in February 2022. The following table summarizes the activities of Performance-Based Awards under the Equity Incentive Plans (amounts in thousands, except share and per share amounts): Performance-Based Awards Outstanding Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Balance - December 31, 2021 400,000 $ 10.12 8.60 $ 3,768 Granted — Exercised — Canceled — Balance - June 30, 2022 400,000 $ 10.12 8.11 $ 358 Vested & expected to vest as of June 30, 2022 400,000 $ 10.12 8.11 $ 358 Exercisable as of June 30, 2022 182,291 $ 10.81 8.30 $ 52 As of June 30, 2022, total compensation cost related to unvested Performance-Based Awards not yet recognized was $0.2 million, which will be recognized over a weighted average period of 0.5 years. Employee stock purchase plan— The 2021 Employee Stock Purchase Plan (the “ESPP”) became effective on October 29, 2021. The Company initially reserved 2,800,000 shares of the Company's common stock under the ESPP. Shares reserved for issuance shall increase on the first day of the fiscal year, beginning in fiscal 2023, in an amount equal to the least of 1% of the outstanding shares of common stock on the last day of the immediately preceding fiscal year, three times the initial number of shares reserved under the ESPP, or a lesser amount determined by the Company’s Board of Directors or compensation committee. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount of 15% during an offering period. Offering periods are 24-month periods beginning on the first trading day on or after May 20 or November 20 (defined as the enrollment date), except for the first offering period which commenced on October 29, 2021, and will end on November 20, 2023. Each offering period has four purchase periods which last approximately 6 months, or the length of time between exercise dates (defined as the first trading day on or after May 20 and November 20 of each purchase period), except that the first purchase period of any offering period is the time between the enrollment date and first exercise date. At the start of an offering period, eligible employees may elect to contribute up to 15% of their eligible compensation each payroll period during that offering period to purchase shares of common stock in accordance with the ESPP. On each exercise date, eligible employees will purchase the Company’s common stock at a price per share equal to 85% of the lesser of the fair market value of the Company’s common stock on (i) the enrollment date or (ii) the exercise date. In the event that the fair market value per share of the Company’s common stock at the end of a six-month purchase period is lower than the fair market value per share at the first day of the related offering period, a reset occurs that automatically cancels the current offering period and enrolls participants in a new offering period. During the six months ended June 30, 2022, 526,754 shares of common stock were issued under the ESPP. The following table summarizes the weighted-average assumptions used in the Black-Scholes option-pricing model to estimate the fair value of new employee stock purchase rights granted under the ESPP: Three and Six Months Ended June 30, 2022 Risk-free interest rate 2.1% Expected volatility 64.2% Expected life (in years) 1.3 Expected dividend yield —% As of June 30, 2022, total unrecognized compensation cost for the ESPP was $8.8 million, which will be recognized over a weighted average period of 1.9 years. Other equity transactions— During the first quarter of 2021, the Company facilitated a tender offer for certain eligible employees to sell 236,086 vested stock options and outstanding shares of common stock to an existing investor at a per share price of $23.75 per share. The Company recorded stock-based compensation of $1.6 million during the six months ended June 30, 2021, in its condensed consolidated statements of operations for the difference be tween the price paid and the fair value of the Company’s common stock on the date of the transaction. On August 24, 2021, the Company issued 61,300 shares of Udemy restricted common stock to a former executive of CorpU at a grant date fair value per share of $34.14. The total compensation cost recognized during the three and six months ended June 30, 2022 was $0.1 million and $0.3 million, respectively. As of June 30, 2022, total compensation cost related to the restricted stock not yet recognized was $1.5 million, which will be recognized over a weighted average period of 2.2 years.

Segment Reporting [Abstract]
Segment and geographic information	16. Segment and geographic information The Company’s Chief Executive Officer is its CODM. The CODM reviews separate financial information presented for the Company’s two segments, Consumer and Enterprise, in order to allocate resources and evaluate the Company’s financial performance. The Consumer segment targets individual learners seeking to obtain hands-on learning, gain valuable job skills to advance their professional careers, or learn a new personal skill. The Enterprise segment is focused on helping business and government customers upskill and reskill their employees and public servants. The CODM measures the performance of each segment primarily based on segment revenue and segment gross profit. Segment gross profit, as presented below, is defined as segment revenue less segment cost of revenue. Segment cost of revenue includes content costs, hosting and platform costs, customer support services, and payment processing fees that are allocable to each segment. Segment gross profit excludes amortization of capitalized software, depreciation, stock-based compensation, and amortization of intangible assets allocated to cost of revenue as the CODM does not include the information in his measurement of the performance of the operating segments. Additionally, the Company does not allocate sales and marketing expenses, research and development expenses, and general and administrative expenses because the CODM does not include the information in his measurement of the performance of the operating segments. The Udemy platform supports the operations of each segment. The CODM does not use asset information by segments to assess performance and make decisions regarding allocation of resources, and the Company does not track its long-lived assets by segment. The geographic identification of these assets is set forth below.

Summary of significant accoun_2

Summary of significant accounting policies (Policies)	6 Months Ended
	Jun. 30, 2022
Accounting Policies [Abstract]
Basis of consolidation and presentation	Basis of consolidation and presentation —The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation, and all other normal and recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results of the periods presented have been made. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which was originally filed with the SEC on March 25, 2022.
Segment information	Segment information —The Company defines its segments as those operations the chief operating decision maker (“CODM”), determined to be the Chief Executive Officer of the Company, regularly reviews to allocate resources and assess performance. For the three and six months ended June 30, 2022 and 2021, the Company operated under two operating and reportable segments: Consumer and Enterprise. The Company continually monitors and reviews its segment reporting structure in accordance with Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting, to determine whether any changes have occurred that would impact its reportable segments. For further information on the Com pany’s segment reporting, see Note 16 – Segment and geographic information.
Use of estimates	Use of estimates —The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the condensed consolidated financial statements and the results of operations during the reporting periods. Significant estimates and assumptions reflected in the condensed consolidated financial statements include, but are not limited to, allowance for doubtful accounts, useful lives of property and equipment, capitalization of internally developed software and associated useful lives, the carrying value of operating lease right-of-use assets, stock-based compensation, determination of the income tax valuation allowance and the potential outcome of uncertain tax positions, estimated instructor withholding tax obligations, estimated period of consumption for consumer learners’ single course purchases, the period of benefit for deferred commissions, the fair value and associated useful lives of intangible assets and goodwill acquired via business combinations, and the valuation of privately-held strategic investments, including impairments. Management periodically evaluates such estimates and assumptions for continued reasonableness. Actual results may ultimately differ from management’s estimates and such differences could be material to the financial position and results of operations.
Concentration of credit risk	Concentration of credit risk —Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, and accounts receivable. For cash, cash equivalents, and restricted cash, the Company is exposed to credit risk in the event of default by the financial institutions to the extent the amounts recorded on the accompanying condensed consolidated balance sheets are in excess of federal insurance limits.
Restricted cash	Restricted cash —Restricted cash primarily consists of cash restricted in connection with lease agreements for the Company’s facilities. Restricted cash is included in current assets for leases that expire within one year from the balance sheet date and in non-current assets for leases that expire in more than one year from the balance sheet date.
Accounts receivable and allowance for doubtful accounts	Accounts receivable and allowance for doubtful accounts— Accounts receivable primarily represent amounts owed to the Company for Enterprise subscriptions. Also included in accounts receivable are amounts due from payment processors or mobile application store partners that settle over a period longer than five business days. Accounts receivable balances are recorded at the invoiced amount and are non-interest-bearing. Accounts receivable are presented net of allowances for doubtful accounts. Management assesses the Company’s ability to collect outstanding receivables and records allowances when collection becomes doubtful. The provision for bad debt is recorded in general and administrative expenses in the accompanying condensed consolidated statements of operations. These estimates are based on the assessment of the credit worthiness of the Company’s customers based on multiple sources of information and analysis of such factors as the Company’s historical collection experience and industry and geographic concentrations of credit risk. Accounts receivable deemed to be uncollectible are written off, net of any amounts that may be collected.
Fair value of financial instruments	Fair value of financial instruments— The Company considers fair value as the exchange price that would be received for an asset or paid to transfer a liability, an exit price, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Valuation techniques used to measure fair value are either observable or unobservable. Observable inputs reflect assumptions that market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity’s pricing based on their own market assumptions. The Company utilizes the following three-level fair value hierarchy to establish the priorities of the inputs used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Inputs are observable, unadjusted quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data; and Level 3—Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable. The carrying amounts of cash, cash equivalents, restricted cash, and accounts receivable, as well as accounts payable, approximate fair value due to the relatively short-term maturities and are classified as short-term assets and liabilities, respectively, in the accompanying condensed consolidated balance sheets.
Operating leases	Operating leases— The Company leases real estate facilities under non-cancelable operating leases with various expiration dates through fiscal year 2026. The Company determines if an arrangement contains a lease at inception based on whether there is an identified tangible asset and whether the Company controls the use of the identified asset throughout the period of use. The Company adopted Accounting Standard Update (“ASU”) No. 2016-02, Leases (Topic 842) on January 1, 2022. Operating leases are included in operating lease right-of-use (“ROU”) assets and in operating lease liabilities in the accompanying condensed consolidated balance sheet. Operating lease ROU assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The Company measures its operating lease liabilities at lease inception date based on the present value of total lease payments over the lease term. Total lease payments are discounted to present value using the more readily determinable of (i) the rate implicit in the lease or (ii) the Company’s incremental borrowing rate (which is the estimated rate the Company would be required to pay for a collateralized borrowing equal to the total lease payments over the term of the lease). Because the Company’s operating leases generally do not provide an implicit rate, the Company estimates its incremental borrowing rate using information available at the lease commencement date, including but not limited to credit rating, lease term, and the currency in which the arrangement is denominated. The Company’s operating lease ROU assets are equal to the corresponding operating lease liability, adjusted for payments made to the lessor at or before the commencement date, initial direct costs incurred, and tenant incentives under the lease. The Company does not assume renewals or early terminations unless it is reasonably certain to exercise these options at commencement. The Company does not allocate consideration between lease and non-lease components. Variable lease payments, such as those for common area maintenance or property taxes, are not included in the measurement of operating lease liabilities and are expensed as incurred. In addition, the Company does not recognize operating ROU assets or operating lease liabilities for leases with a term of 12 months or less for all asset classes. Operating lease expense is recognized on a straight-line basis over the lease term.
Recently Adopted Accounting Pronouncements and New accounting pronouncements not yet adopted	Recently Adopted Accounting Pronouncements —In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted the standard with an effective date of January 1, 2021 using the prospective transition adoption approach. Capitalized implementation costs are recorded in prepaid expenses and other current assets and other assets in the condensed consolidated balance sheet. The adoption of this ASU did not have a material impact on the condensed consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires a lessee to record an asset representing the lessees’ right to use the underlying asset and a liability to make lease payments. At inception, lessees must classify all leases as either finance or operating based on five criteria. Balance sheet recognition of finance and operating leases is similar, but the pattern of expense recognition in the income statement, as well as the effect on the statement of cash flows, differs depending on the lease classification. The Company adopted Topic 842 on January 1, 2022, using the modified retrospective approach. The Company elected the package of practical expedients, the use of hindsight in determining the lease term, and the practical expedient to not recognize an operating ROU asset or operating lease liability for leases with a term of 12 months or less. Upon adoption, the Company recognized $17.6 million in operating ROU assets and $20.0 million in operating lease liabilities in its condensed consolidated balance sheets. The difference between the amounts of operating ROU assets and operating lease liabilities consisted of deferred rent and prepaid rent that were derecognized upon transition. There was no adoption date impact to accumulated deficit, and adoption of the new standard did not have a material impact on the Company’s condensed consolidated statements of operations or cash flows. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which aims to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to (1) recognition of an acquired contract liability and (2) payment terms and their effect on subsequent revenue recognized by the acquirer. The Company elected to early adopt this standard on a prospective basis on January 1, 2022. There has been no impact of adoption to date, as the Company has not entered into any business combinations since adoption. The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, EGCs can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, the condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. Based on the market value of its common stock held by non-affiliates as of the last business day of the second fiscal quarter ended June 30, 2022, the Company will cease to be an EGC on December 31, 2022. New accounting pronouncements not yet adopted —In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. The FASB issued ASU 2019-10 in November 2019, which deferred the effective date for nonpublic entities, including EGCs, that had not yet adopted the original ASU. The Company will meet the criteria to become a large accelerated filer as of December 31, 2022, upon which time the ASU will become effective for the fiscal year ending on December 31, 2022. The Company is currently assessing the potential impact of the new standard on the Company’s condensed consolidated financial statements. In December 31, 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles of income taxes and reducing the cost and complexity in accounting for income taxes. The ASU is effective for the Company’s fiscal year beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company is currently assessing the potential impact of the new standard on the Company’s condensed consolidated financial statements.
