Overview and Basis of Presentation	Overview and Basis of Presentation Description of Business Eventbrite, Inc. (Eventbrite or the Company) has built a powerful, broad technology platform to enable creators to solve the challenges associated with creating live experiences. The Company’s platform integrates components needed to seamlessly plan, promote and produce live events, thereby allowing creators to reduce friction and costs, increase reach and drive ticket sales. Initial Public Offering In September 2018, the Company completed its initial public offering (IPO) in which the Company issued and sold 11,500,000 shares of Class A common stock at a public offering price of $23.00 per share, which included 1,500,000 shares sold pursuant to the exercise by the underwriters' option to purchase additional shares. The Company received aggregate net proceeds of $246.0 million from the IPO, net of underwriter discounts and commissions, before deducting offering costs of $5.5 million, net of reimbursements. Immediately prior to the closing of the IPO, (i) all shares of common stock then outstanding were reclassified as Class B Common Stock, (ii) 41,628,207 shares of redeemable convertible preferred stock outstanding converted into 42,188,624 shares of Class B common stock (including additional shares issued upon conversion of the Series G redeemable convertible preferred stock based on the IPO price of $23.00 per share) and (iii) warrants to purchase 933,269 shares of the Series G redeemable convertible preferred stock automatically exercised into 997,193 shares of Class B common stock. See Note 12 and Note 13 for additional details. Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and accounts have been eliminated. Prior Period Reclassification Beginning in the first quarter of 2019, the Company classified the amortization of acquired customer relationship intangible assets and certain other costs as sales, marketing and support expenses. Previously, these expenses were classified as general and administrative expenses. The Company has reclassified $13.6 million and $4.6 million of expenses for the years ended December 31, 2018 and 2017, respectively, to make the presentation consistent with the current year. There was no change to total operating expenses, loss from operations, loss before income taxes or net loss for the years ended December 31, 2018 or 2017 as a result of these reclassifications. Use of Estimates In order to conform with GAAP, the Company is required to make certain estimates, judgments and assumptions when preparing its consolidated financial statements. These estimates, judgments and assumptions affect the reported assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reported periods. These estimates include, but are not limited to, the recoverability of creator signing fees and creator advances, the capitalization and estimated useful life of internal-use software, certain assumptions used in the valuation of equity awards, determining the fair value of the Company's common stock and redeemable convertible preferred stock warrant liability prior to the IPO, fair value of the term loan derivative liability, assumptions used in determining the fair value of business combinations, the allowance for doubtful accounts, indirect tax reserves and contra-revenue amounts related to fraudulent events, customer disputed transactions and refunds. The Company evaluates these estimates on an ongoing basis. Actual results could differ from those estimates and such differences could be material to the Company’s consolidated financial statements. SEC Filer and Emerging Growth Company Status The Company became a large accelerated filer on December 31, 2019, based on the market value of the Company's Class A common stock held by non-affiliates as of the last day of the second quarter. Prior to that, the Company was an emerging growth company (EGC) as defined in the Jumpstart Our Business Startups Act (JOBS Act). Being an EGC allowed the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The Company had elected to use this extended transition period under the JOBS Act. The Company lost the ability to delay adoption of new or revised accounting pronouncements when it ceased to be an EGC and became a large accelerated filer as of December 31, 2019. As a result, the financial statements included in this Annual Report on Form 10-K reflect the adoption of new accounting standards effective for calendar year end public companies, including the adoption of ASU 2016-02, Leases (Topic 842) (ASC 842). The Company previously filed its 2019 quarterly interim financial statements on Form 10-Q accounting for its leases under ASC 840, Leases (ASC 840), and has recast its previously reported 2019 interim financial information to be reported under ASC 842 in this Annual Report on Form 10-K. Refer to the section titled Recently Adopted Accounting Pronouncements below for more information. Comprehensive Loss For all periods presented, comprehensive loss equaled net loss. Therefore, the consolidated statements of comprehensive loss have been omitted from the consolidated financial statements. Segment Information The Company’s Chief Executive Officer (CEO) is the chief operating decision maker. The Company's CEO reviews discrete financial information presented on a consolidated basis for purposes of allocating resources and evaluating the Company’s financial performance. Accordingly, the Company has determined that it operates as a single operating segment and has one reporting unit.
