Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company and Summary of Significant Accounting Policies	The Company and Summary of Significant Accounting Policies The Company eBay Inc. is a global commerce leader, which includes our Marketplace, StubHub and Classifieds platforms. Our Marketplace platforms include our online marketplace located at www.ebay.com, its localized counterparts and the eBay mobile apps. Our StubHub platforms include our online ticket platform located at www.stubhub.com, its localized counterparts and the StubHub mobile apps. Our Classifieds platforms include a collection of brands such as Mobile.de, Kijiji, Gumtree, Marktplaats, eBay Kleinanzeigen and others. When we refer to “we,” “our,” “us” or “eBay” in this Quarterly Report on Form 10-Q, we mean the current Delaware corporation (eBay Inc.) and its California predecessor, as well as all of our consolidated subsidiaries, unless otherwise expressly stated or the context otherwise requires. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“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 date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those related to provisions for transaction losses, legal contingencies, income taxes, revenue recognition, stock-based compensation, goodwill and the recoverability of intangible assets. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from those estimates. Principles of Consolidation and Basis of Presentation The accompanying condensed financial statements are consolidated and include the financial statements of eBay Inc., our wholly and majority-owned subsidiaries and variable interest entities (“VIE”) where we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. Minority interests are recorded as a noncontrolling interest. A qualitative approach is applied to assess the consolidation requirement for VIEs. Investments in entities where we hold at least a 20% ownership interest and have the ability to exercise significant influence, but not control, over the investee are accounted for using the equity method of accounting. For such investments, our share of the investees’ results of operations is included in interest and other, net and our investment balance is included in long-term investments. Investments in entities where we hold less than a 20% ownership interest are generally accounted for using the cost method of accounting, and our share of the investees’ results of operations is included in our condensed consolidated statement of income to the extent dividends are received. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2016. We have evaluated all subsequent events through the date these condensed consolidated financial statements were issued. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for fair statement of the condensed consolidated financial position, results of operations and cash flows for these interim periods. Recently Adopted Accounting Pronouncements In 2016, the FASB issued new guidance to revise certain aspects of stock-based compensation guidance which includes income tax consequences, classification of awards as equity or liabilities, and classification on the statement of cash flows. We adopted the new standard in the first quarter of 2017. Adoption of this standard did not have a material impact on our consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In 2014, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance related to revenue recognition. This new standard will replace all current GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition guidance provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. In 2016, the FASB issued several amendments to the standard, including principal versus agent considerations when another party is involved in providing goods or services to a customer and the application of identifying performance obligations. While we continue to assess all potential impacts of the standard, we currently identified one performance obligation related to the core service offered to sellers in our Marketplace platform and believe additional services mainly to promote or feature listings at the option of sellers are not distinct within the context of the contract. Accordingly, certain fees paid by sellers for these services will be recognized when the single performance obligation is satisfied resulting, in some cases, in a change in the timing of recognition from current guidance. We do not anticipate that the principal versus agent considerations under ASU 2016-08 Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) will materially change how we present revenue. Further, we believe certain incentives such as coupons and rewards provided to our users could potentially be recognized as an expense, which we generally record as a reduction of revenue under current guidance. The standard is required to be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application. We continue to evaluate the transition method upon adoption. The Company will adopt the new revenue standards in its first quarter of 2018. In 2016, the FASB issued new guidance related to accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements. In 2016, the FASB issued new guidance related to accounting for leases. The new guidance requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements. In 2016, the FASB issued new guidance that requires credit losses on financial assets measured at amortized cost basis to be presented at the net amount expected to be collected, not based on incurred losses. Further, credit losses on available-for-sale debt securities should be recorded through an allowance for credit losses limited to the amount by which fair value is below amortized cost. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 is permitted. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements. In 2016, the FASB issued new guidance that clarifies the classification of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs, settlement of contingent consideration arising from a business combination, insurance settlement proceeds, and distributions from certain equity method investees. Additionally, the FASB issued new guidance to include restricted cash with cash and cash equivalents when reconciling the beginning-of-the-period and end-of-the-period total amounts shown on the statement of cash flows. The new standards are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. While we continue to assess the potential impact of this standard, we do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In 2016, the FASB issued new guidance that requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. This removes the exception to postpone recognition until the asset has been sold to an outside party. This standard is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods, with early adoption permitted. It is required to be applied on a modified retrospective basis through a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements. In 2017, the FASB issued new guidance that narrows the application of when an integrated set of assets and activities is considered a business and provides a framework to assist entities in evaluating whether both an input and a substantive process are present to be considered a business. It is expected that the new guidance will reduce the number of transactions that would need to be further evaluated and accounted for as a business. This standard is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods, with early adoption permitted. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements. In 2017, the FASB issued new guidance to simplify the subsequent measurement of goodwill by removing the requirement to perform a hypothetical purchase price allocation to compute the implied fair value of goodwill to measure impairment. Instead, any goodwill impairment will equal the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Further, the guidance eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. This standard is effective for annual or any interim goodwill impairment test in fiscal years beginning after December 15, 2019, with early adoption permitted for impairment tests performed after January 1, 2017. While we continue to assess the potential impact of this standard, we do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In 2017, the FASB issued new guidance to clarify the scope and application of the sale or transfer of nonfinancial assets to noncustomers, including partial sales and also defines what constitutes an “in substance nonfinancial asset” which can include financial assets. The new guidance eliminates several accounting differences between transactions involving assets and transactions involving businesses. Further, the guidance aligns the accounting for derecognition of a nonfinancial asset with that of a business. This standard is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements. In 2017, the FASB issued new guidance that will shorten the amortization period for certain callable debt securities held at a premium to the earliest call date to more closely align with expectations incorporated in market pricing. The new guidance will not impact debt securities held at a discount. Adoption of this standard will be made on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. This standard is effective for annual reporting periods beginning after December 15, 2018, including interim reporting periods within those annual reporting periods, with early adoption permitted. While we continue to assess the potential impact of this standard, we do not expect the adoption of this standard to have a material impact on our consolidated financial statements In 2017, the FASB issued new guidance to amend the scope of modification accounting for share-based payment arrangements. The amendments in the update provide guidance on types of changes to the terms or conditions of share-based payment awards would be required to apply modification accounting under ASC 718, Compensation-Stock Compensation. The amendments are effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements.
