Basis of Presentation and Summary of Significant Accounting Policies | Note 1—Basis of Presentation and Summary of Significant Accounting Policies Description of Business Etsy operates two-sided online marketplaces that connect millions of passionate and creative buyers and sellers around the world. These marketplaces - which collectively create a “House of Brands” - share the Company’s mission, common levers for growth, similar business models, and a strong commitment to use the power of business and technology to strengthen communities and empower people. The Company’s primary marketplace, Etsy.com, is the global destination for unique and creative goods. The Company generates revenue primarily from marketplace activities, including transaction, listing, and payments processing fees, and fees for optional seller services, which include on-site advertising and shipping label services. Basis of Consolidation The consolidated financial statements include the accounts of Etsy, Inc. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. On July 12, 2021, Etsy acquired all of the issued share capital of Depop Limited (“Depop”) pursuant to a share purchase, and on July 2, 2021, Etsy acquired all the outstanding shares of Elo7 Serviços de Informática S.A. (“Elo7”) by means of a merger. The financial results of Depop and Elo7 have been included in Etsy’s consolidated financial statements from the dates of acquisition. See “Note 5—Business Combinations.” Reclassification Certain items in the prior years consolidated financial statements have been reclassified to conform to the current year presentation reflected in the consolidated financial statements. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires the Company to make estimates and judgments that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and judgments. The accounting estimates that require management’s most subjective judgments include: stock-based compensation; income taxes; the valuation of acquired intangible assets, developed technology, and goodwill as part of purchase price allocations for business combinations; valuation of goodwill; leases; and fair value of convertible senior notes. As of December 31, 2022, the Company continues to monitor the effects of global macroeconomic and geopolitical uncertainty, including COVID-19 pandemic related factors and general market, political, and economic conditions, on the Company’s business, results of operations, and financial condition. As a result, many of the Company’s estimates and judgments require increased judgment and carry a higher degree of variability and volatility. As additional information becomes available, the Company’s estimates may change materially in future periods. Revenue Recognition The Company’s revenue is diversified; generated from a mix of marketplace activities and other optional services the Company provides to sellers to help them generate more sales and scale their businesses. Revenues are recognized as the Company transfers control of promised goods or services to sellers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company evaluates whether it is appropriate to recognize revenue on a gross or net basis based upon its evaluation of whether the Company obtains control of the specified goods or services by considering if it is primarily responsible for fulfillment of the promise, has inventory risk, and has the latitude in establishing pricing and selecting suppliers, among other factors. Based on its evaluation of these factors, revenue is recorded either gross or net of costs associated with the transaction. The Company’s revenues are recognized on a gross basis, with the primary exception being shipping label revenue, which is recorded on a net basis. Sales and usage-based taxes are excluded from revenues. Marketplace revenue: As members of the Etsy.com marketplace, Etsy sellers receive the benefit of marketplace activities, including listing items for sale, completing sales transactions, and payments processing, which represents a single stand-ready performance obligation. Etsy marketplace sellers pay a fixed listing fee of $0.20 for each item listed on Etsy.com, and the listing fee is recognized ratably over a four-month listing period, unless the item is sold or the seller re-lists it, at which time any remaining listing fee is recognized. Listing fees are nonrefundable. Variable fees include transaction fees and payments processing fees. Etsy marketplace sellers pay a 6.5% transaction fee, which was increased from 5% effective April 11, 2022, for each completed transaction, inclusive of shipping fees charged. In May 2020, the Etsy marketplace started charging sellers for Offsite Ads, whereby sellers pay a transaction fee of 12% or 15% of the value of a sale based on the seller’s volume of sales, if such sale is generated from an advertisement placed by Etsy on third-party internet platforms. The corresponding expense is recorded in marketing. Etsy marketplace sellers pay Etsy Payments processing fees, which typically vary between 3.0% and 4.5% of an item’s total sale price, including shipping, plus a flat fee per order that depends on the country in which a seller’s bank account is located, plus an additional transaction fee for foreign currency payments. The transaction fee, Offsite Ads transaction fee, and Etsy Payments processing fees are recognized when the corresponding transaction is consummated, and are recorded net of refunds. Reverb, Depop, and Elo7 marketplace revenue is comprised of seller transaction fees and payments processing fees, which are recognized when the transaction is consummated, and are recorded net of refunds. Reverb, Elo7, and Depop sellers pay a 5%, 7%, and 10% transaction fee, respectively, for each completed transaction. The Reverb and Depop transaction fee is inclusive of shipping fees charged. Services revenue: Services revenue is derived from optional services offered to Etsy marketplace sellers, which primarily include on-site advertising and shipping labels. Each service represents an individual obligation that the Company must perform when a seller chooses to use the service. On-site advertising services consist of cost-per-click fees an Etsy marketplace seller pays for prominent placement of her listings. These fees are nonrefundable and are charged to a seller’s Etsy bill when the listing is clicked, at which time revenue is recognized. Revenue from shipping labels consists of fees an Etsy marketplace seller pays the Company when she purchases shipping labels through its platform, net of the cost the Company incurs in purchasing those shipping labels. The Company provides its sellers access to purchase shipping labels at discounted pricing due to the volume of purchases through its platform. The Company recognizes shipping label revenue when an Etsy marketplace seller purchases a shipping label. The Company recognizes shipping label revenue on a net basis as it is an agent in this arrangement and does not take control of shipping labels prior to transferring the labels to the Etsy marketplace seller. Etsy shipping label revenue is recorded net of refunds. The Reverb, Depop, and Elo7 marketplaces offer on-site advertising services (Depop as of the end of the third quarter of 2022), and shipping labels services. Each service represents an individual obligation that the Company must perform when a seller chooses to use the service. Shipping label revenue is recorded net of refunds. Contract balances: The Company records deferred revenues when cash payments are received or due in advance of the completion of the four-month listing period on Etsy.com, which represents the value of the Company’s unsatisfied performance obligations, unless the item is sold or the seller re-lists it, at which time any remaining listing fee is recognized. The amount of revenue recognized in the year ended December 31, 2022 that was included in the deferred balance at January 1, 2022 was $12.3 million. Cost of Revenue Cost of revenue primarily consists of the cost of interchange and other fees for payments processing services, and expenses associated with the operation and maintenance of the Company’s platforms, including hosting and bandwidth costs. Cost of revenue also includes chargebacks to support payments revenue, costs of refunds made to buyers that the Company is either not able to collect from sellers or are otherwise covered by us, and seller verification fees. Additionally, cost of revenue includes certain employee compensation-related expenses, depreciation and amortization, and third-party customer support services. Marketing Marketing expenses primarily consist of direct marketing expenses, which largely includes digital marketing and television ad and digital video expenses. Marketing expenses also include employee compensation-related expenses to support the Company’s marketing initiatives and amortization expense related to acquired customer relationship and trademark intangible assets. Advertising expenses are recognized as incurred, with the exception of certain production expenses related to television and display advertising which are deferred until the first time an advertisement airs or is published. If such advertising is not expected to occur, costs are expensed immediately. Advertising expenses related to direct marketing, included in marketing expenses on the Consolidated Statements of Operations, were $581.1 million, $559.3 million, and $442.2 million in the years ended December 31, 2022, 2021, and 2020, respectively. Product Development Product development expenses consist primarily of employee compensation-related expenses for engineering, product management, product design, and product research activities, net of costs capitalized to website development and internal-use software. Additional expenses include consulting costs related to the development, quality assurance, and testing of new technology and enhancement of the Company’s existing technology. Stock-Based Compensation Service-based stock options and restricted stock units (“RSUs”) are awarded to employees and members of the Company’s Board of Directors and performance-based restricted stock units (“PBRSUs”) are awarded to employees. All such awards are measured at fair value at each grant date. The PBRSUs include financial performance-based restricted stock units (“Financial PBRSUs”) and total shareholder return performance-based restricted stock units (“TSR PBRSUs”), both of which have performance and service vesting requirements. The Company recognizes forfeitures as they occur. The Company calculates the fair value of stock options on the date of grant using the Black-Scholes option-pricing model and the expense is recognized over the requisite service period. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The Company calculates expected volatility based on the historical volatility of Etsy’s stock price observations over a period equivalent to the expected term of the stock option grants. The Company estimates its expected term using historical option exercise behavior and expected post-vest cancellation data, averaged with an assumption that recently granted options will be exercised ratably from vesting to the expiration of the stock option. The fair value of RSUs and Financial PBRSUs is determined based on the closing price of the Company’s common stock on Nasdaq on the grant date. Additionally, the fair value of the Financial PBRSUs takes into consideration a vesting probability assessment as of each reporting date. The fair value of the TSR PBRSUs is determined using a Monte-Carlo simulation model on the grant date. The requisite service period for stock options and RSUs is generally four years from the grant date. For PBRSUs, the Company recognizes stock-based compensation expenses on a straight-line basis over the longer of the derived, explicit, or implicit service period. As of interim and annual reporting periods, the Financial PBRSUs stock-based compensation expense is adjusted based on expected achievement of performance targets, while TSR PBRSUs stock-based compensation expense is not adjusted. Foreign Currency The Company has determined that the functional currency for each of its foreign operations is the currency of the primary cash flow of the operations, which is generally the local currency in which the operation is located. All assets and liabilities are translated into U.S. dollars using exchange rates in effect at the balance sheet date. Revenue and expenses are translated using average exchange rates during the period. Foreign currency translation adjustments are reflected in stockholders’ equity as a component of other comprehensive income (loss). Transaction gains and losses including intercompany balances denominated in a currency other than the functional currency of the entity involved are included in foreign exchange gain (loss) within other income (expense) in the Consolidated Statements of Operations. Income Taxes The income tax benefit is based on income before income taxes and is accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to settle. The Company recognizes future tax benefits, such as net operating losses and tax credits, to the extent that realizing these benefits is considered in its judgment to be more likely than not. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date. The Company regularly reviews the recoverability of its deferred tax assets by considering its historic profitability, projected future taxable income, timing of the reversals of existing temporary differences and the feasibility of its tax planning strategies. Where appropriate, the Company records a valuation allowance against deferred tax assets that are deemed not more likely than not to be realizable. The Company records tax expense related to Global Intangible Low Taxed Income (“GILTI”) as a current period expense when incurred using the period cost method. The Company accounts for uncertainty in income taxes using a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by the taxing authorities. The amount recognized is measured as the largest amount of benefit that has a greater than 50% likelihood of being realized upon ultimate audit settlement. The Company recognizes interest and penalties, if any, associated with income tax matters as part of the income tax provision and includes accrued interest and penalties with the related income tax liability in the Consolidated Balance Sheets. Net (Loss) Income Per Share Basic net (loss) income per share attributable to common stockholders is computed by dividing the net (loss) income attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Diluted net (loss) income per share is computed by dividing net (loss) income adjusted on an if-converted basis for the period by the weighted-average number of shares of common stock and potentially dilutive common stock outstanding during the period. Potentially dilutive shares, which are based on the weighted-average shares of common stock underlying outstanding stock-based compensation awards and convertible senior notes using the treasury stock method or the if-converted method, as applicable, are included when calculating net (loss) income per share of common stock attributable to common stockholders when their effect is dilutive. The calculation of diluted net income per share excludes all anti-dilutive shares of common stock. Segment Data The Company identifies operating segments as components of an entity for which discrete financial information is available and is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in making decisions regarding resource allocation and performance assessment. The Company’s CODM is its Chief Executive Officer. The Company has determined it has four operating segments, Etsy, Reverb, Depop, and Elo7, which qualify for aggregation as one reportable segment. Cash and Cash Equivalents, and Short- and Long-term Investments The Company considers all investments with an original maturity of three months or less at time of purchase to be cash equivalents. Cash restricted by third parties is not considered cash and cash equivalents. Short-term investments, consisting of certificates of deposit, commercial paper, corporate bonds, U.S. agency securities, and U.S. Government securities with original maturities of greater than three months but less than one year, are classified as available-for-sale and are reported at fair value using the specific identification method. Long-term investments, consisting of corporate bonds and U.S. Government securities with original maturities of greater than twelve months but less than 37 months, are classified as available-for-sale and are reported at fair value using the specific identification method. Unrealized gains and losses are excluded from earnings and reported as a component of other comprehensive income (loss), net of related tax (expense) benefit. Restricted Cash The Company classifies any cash balances that are legally restricted as to withdrawal or usage as restricted cash on the Consolidated Balance Sheets. In connection with the Company’s noncancellable Brooklyn lease agreement, which expires in 2039, the Company established a $5.3 million collateral account, which is reflected in the restricted cash balance as of December 31, 2022 and 2021. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, short- and long-term investments, and funds receivable and seller accounts. The Company reduces credit risk by placing its cash and cash equivalents with major financial institutions with high credit ratings. At times, to the extent eligible, such amounts may exceed federally insured limits. The Company believes that minimal credit risk exists with respect to these investments due to the credit ratings of the financial institutions that hold its short- and long-term investments. In addition, funds receivable settle relatively quickly, and the Company’s historical experience of losses has not been significant. Fair Value of Financial Instruments Management believes that the fair value of financial instruments, consisting of cash and cash equivalents, short- and long-term investments, accounts receivable, funds receivable and seller accounts, accounts payable, and funds payable and amounts due to sellers approximates carrying value due to the immediate or short-term maturity associated with these instruments or the Company’s ability to liquidate these instruments at short notice with minimal penalties. Prior to the adoption of ASU 2020-06 in the first quarter of 2021, in accounting for the issuance of the 0.125% Convertible Senior Notes due 2027 (the “2020 Notes”), the 0.125% Convertible Senior Notes due 2026 (the “2019 Notes”), and the 2018 Notes (collectively, the 0.25% Convertible Senior notes due 2028 (the “2021 Notes”), the 2020 Notes, the 2019 Notes, and the 2018 Notes, the “Notes”), and the extinguishment of the 2018 Notes, discussed in “Note 12—Debt,” management used estimates and assumptions to calculate the carrying amounts of the liability and equity components by measuring the fair value of similar securities. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. To measure the fair value of a similar liability that does not have an associated convertible feature, the Company discounted the contractual cash flows of each of the Notes at an estimated interest rate for a comparable liability. The carrying amount of the equity component, representing the conversion option, which does not meet the criteria for separate accounting as a derivative as it is indexed to the Company’s stock, was determined by deducting the fair value of the liability component from the par value of each of the Notes. Following the adoption of ASU 2020-06, there is no bifurcation of the liability and equity components of the Notes. Subsequent to their issuance, the Notes are not measured at fair value in the Consolidated Balance Sheets, but the Company estimates the fair value of the liability component of the Notes through inputs that are observable in the market or that could be derived from observable market data, corroborated with quoted market prices of similar instruments. See Note 8—Fair Value Measurements for additional information. Accounts Receivable and Provision for Expected Credit Losses The Company’s trade accounts receivable are recorded at amounts billed to sellers and are presented on the Consolidated Balance Sheets net of the provision for expected credit losses. The provision is determined by a number of factors, including age of the receivable, current economic conditions, historical losses, and management’s assessment of the financial condition of sellers. Receivables are written off once they are deemed uncollectible. Estimates of uncollectible accounts receivable are recorded to general and administrative expense. Payment terms: On the first day of every month, Etsy sellers receive a statement outlining the previous month’s charges. Payment is due within 15 days of the date of the monthly statement. The payment terms for Reverb, Depop, and Elo7 are also short-term in nature. For Etsy sellers using Etsy Payments, all charges are deducted from the funds credited to the seller’s shop payment account prior to settlement of those funds to the seller’s bank account. The following table provides a rollforward of the allowance for credit losses that is deducted from the amortized cost basis of accounts receivable to present the net amount expected to be collected (in thousands): Year Ended 2022 2021 2020 Balance as of the beginning of period $ 7,730 $ 9,757 $ 5,033 Provision for expected credit losses 12,464 16,031 15,033 Amounts written off, net of recoveries (11,891) (18,058) (10,309) Balance as of the end of period $ 8,303 $ 7,730 $ 9,757 Funds Receivable and Seller Accounts and Funds Payable and Amounts due to Sellers The Company records funds receivable and seller accounts and funds payable and amounts due to sellers as current assets and liabilities, respectively, on the Consolidated Balance Sheets. Funds receivable and seller accounts represent amounts received or expected to be received from buyers via third-party credit card processors, which flow through a bank account for payment to sellers. The amounts recorded to funds receivable and seller accounts is the same amount recorded to the funds payable and amounts due to sellers, the latter of which represents the total amount due to sellers, given the intent to use these funds to settle funds payable to sellers. For the Depop marketplace only, the amounts received from buyers which is owed to the sellers is paid to the sellers at point of sale, and therefore no funds receivable and seller accounts and no funds payable and amounts due to sellers are recorded related to the Depop marketplace. Property and Equipment Property and equipment, consisting principally of capitalized website development and internal-use software, building, leasehold improvements, and computer equipment, are recorded at cost. Depreciation and amortization begin at the time the asset is placed into service and is recognized using the straight-line method in amounts sufficient to relate the cost of depreciable and amortizable assets to the Consolidated Statements of Operations over their estimated useful lives. Repairs and maintenance are charged to the Consolidated Statements of Operations as incurred. Upon sale or retirement of assets, the cost and related accumulated depreciation or amortization are removed from the Consolidated Balance Sheet and the resulting gain or loss is reflected in the Consolidated Statement of Operations. Website Development and Internal-use Software Costs Costs incurred to develop the Company’s website and software for internal-use are capitalized and amortized over the estimated useful life of the software, generally three Capitalized website development and internal-use software costs are included in property and equipment, net within the Consolidated Balance Sheets. Business Combinations The Company accounts for business combinations using the acquisition method of accounting. If the assets acquired are not a business, the Company accounts for the transaction as an asset acquisition. Under both methods, the purchase price is allocated to the assets acquired and liabilities assumed using the fair values determined by management as of the acquisition date. The results of businesses acquired in a business combination are included in the Company’s consolidated financial statements from the date of acquisition. Acquisition-related expenses represent expenses incurred by the Company to effect a business combination, including expenses such as finder’s fees and advisory, legal, accounting, valuation, and other professional or consulting fees, and are not included as a component of consideration transferred, but are accounted for as an expense in the period in which the costs are incurred or the services are rendered. Goodwill Goodwill represents the excess of the aggregate fair value of the consideration transferred in a business combination over the fair value of the assets acquired, net of liabilities assumed. The Company performs its annual goodwill impairment test during the fourth quarter or more frequently if events or changes in circumstances indicate that the goodwill may be impaired. Management has determined that the Company has four operating segments, Etsy, Reverb, Depop, and Elo7, and each operating segment is determined to be a reporting unit. The Company has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, the Company determines it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then additional impairment testing is not required. However, if the Company concludes otherwise, then it is required to perform a quantitative assessment for impairment. The quantitative assessment involves comparing the estimated fair value of the reporting unit with its respective book value, including goodwill. If the estimated fair value exceeds book value, goodwill is not considered to be impaired. If, however, the book value of the reporting unit exceeds the fair value, an impairment loss is recognized in an amount equal to the excess, not to exceed the total amount of goodwill allocated to that reporting unit. See “Note 6—Goodwill and Intangible Assets” for further information. Intangible Assets Finite intangible assets are amortized using the straight-line method over the estimated useful life of the asset. Leases The Company’s lease arrangements generally include real estate and computer equipment assets. At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. At lease commencement, the Company evaluates whether the arrangement is a finance or operating lease, and accounts for it accordingly. Operating leases are included in other assets, other current liabilities, and other liabilities on the Company’s Consolidated Balance Sheets. Finance leases are included in property and equipment, net, finance lease obligations, current, and finance lease obligations, net of current portion on the Company’s Consolidated Balance Sheets. Leases with a term greater than one year are recognized on the Consolidated Balance Sheets as right-of-use (“ROU”) assets, lease obligations, and, if applicable, long-term lease obligations in the financial statement line items cited above. The Company has elected not to recognize leases with terms of one year or less on the Consolidated Balance Sheets. Lease obligations and their corresponding ROU assets are recorded based on the present value of lease payments over the expected lease term. As the interest rate implicit in lease contracts is typically not readily determinable, the Company utilizes the appropriate incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term in an amount equal to the lease payments in a similar economic environment. Certain adjustments to the ROU asset may be required for items such as initial direct costs paid or incentives received. The lease term may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The components of a lease are split into three categories: lease components, including land, building, or other similar components; non-lease components, including common area maintenance, maintenance, consumables, or other similar components; and non-components, including property taxes, insurance, or other similar components. However, the Company has elected to combine lease and non-lease components as a single component. The lease expense is recognized over the expected term on a straight-line basis. Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets held and used is measured by comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated from the use of the asset and its eventual disposition. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount exceeds the fair value of the impaired assets. Assets to be disposed of are reported at the lower of their carrying amount or fair value less cost to sell. The Company did not recognize any long-lived asset impairment charges in the years ended December 31, 2022, 2021, and 2020. See “Note 6—Goodwill and Intangible Assets” for further information. Contingencies The Company accrues for loss contingencies when losses become probable and are reasonably estimable. If the reasonable estimate of the loss is a range and no amount within the range is a better estimate, the minimum amount of the range is recorded as a liability. The Company does not accrue for contingent losses that, in its judgment, are considered to be reasonably possible, but not probable; however, it discloses the range of such reasonably possible losses. |
