Overview and Summary of Significant Accounting Policies | Overview and Summary of Significant Accounting Policies Overview and Organization PayPal Holdings, Inc. (“PayPal,” the “Company,” “we,” “us,” or “our”) was incorporated in Delaware in January 2015 and is a leading technology platform and digital payments company that enables digital and mobile payments on behalf of merchants and consumers worldwide. PayPal is committed to democratizing financial services and empowering people and businesses to join and thrive in the global economy. Our goal is to enable our merchants and consumers to manage and move their money anywhere in the world, anytime, on any platform, and using any device. We also facilitate person-to-person payments through our PayPal, Venmo, and Xoom products. Our combined payment solutions, including our PayPal, PayPal Credit, Braintree, Venmo, Xoom, and iZettle products, comprise our proprietary Payments Platform. The terms “we,” “our,” “us,” “the Company,” and “PayPal” mean PayPal Holdings, Inc. and, unless otherwise expressly stated or the context requires, its subsidiaries. We operate globally and in a rapidly evolving regulatory environment characterized by a heightened regulatory focus on all aspects of the payments industry. That focus continues to become even more heightened as regulators on a global basis focus on important issues such as countering terrorist financing, anti-money laundering, privacy, cybersecurity, and consumer protection. Some of the laws and regulations to which we are subject were enacted recently, and the laws and regulations applicable to us, including those enacted prior to the advent of digital and mobile payments, are continuing to evolve through legislative and regulatory action and judicial interpretation. New or changing laws and regulations, including the way laws and regulations are interpreted and implemented, as well as increased penalties and enforcement actions related to non-compliance, could have a material adverse impact on our business, results of operations, and financial condition. Therefore, we monitor these areas closely to design compliant solutions for our customers who depend on us. Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include the financial statements of PayPal and our wholly- and majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Noncontrolling interest reported as a component of equity on our consolidated balance sheets represents the equity interests not owned by PayPal and is recorded for consolidated entities we control in which we own less than 100%. Noncontrolling interest is not presented separately on our consolidated statements of income as the amount is de minimis. Investments in entities where we 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 investee’s results of operations is included in other income (expense), net on our consolidated statements of income and our investment balance is included in long-term investments on our consolidated balance sheets. Investments in entities where we do not have the ability to exercise significant influence over the investee are accounted for at fair value or cost minus impairment, if any, adjusted for changes resulting from observable price changes, which are included in other income (expense), net on our consolidated statements of income. Our investment balance is included in long-term investments on our consolidated balance sheets. In the opinion of management, these consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair statement of the consolidated financial statements for all periods presented. Certain amounts for prior years have been reclassified to conform to the financial statement presentation as of and for the year ended December 31, 2019 . Reclassifications Beginning with the first quarter of 2019, we reclassified certain operating expenses within the consolidated statements of income. Prior period amounts have been reclassified to conform to this presentation. These changes have no impact on our previously reported consolidated net income for prior periods, including total operating expenses, financial position, or cash flows for any periods presented. The classification changes related primarily to the combination of costs incurred to develop and operate our Payments Platform into a new caption entitled technology and development. This new caption includes: (a) costs incurred in operating, maintaining, and enhancing our Payments Platform, including network and infrastructure costs, which were previously classified in the customer support and operations caption, and (b) costs incurred in developing new and improving existing products, which were previously classified in the product development caption on our consolidated statements of income. In addition, we eliminated the presentation of depreciation and amortization expense as a separate financial statement caption by reclassifying these expenses into financial statement captions aligned with the internal organizations that are the primary beneficiaries of the depreciation and amortization of such assets. The following tables present the effects of the changes on the presentation of these operating expenses to the previously reported consolidated statements of income: Year Ended December 31, 2018 (In millions) As Previously Reported (*) Adjustments Reclassified Transaction expense $ 5,581 $ — $ 5,581 Transaction and loan losses 1,274 — 1,274 Customer support and operations 1,482 (75 ) 1,407 Sales and marketing 1,313 1 1,314 Product development 1,071 (1,071 ) — Technology and development — 1,831 1,831 General and administrative 1,451 90 1,541 Depreciation and amortization 776 (776 ) — Restructuring and other charges 309 — 309 Total operating expenses $ 13,257 $ — $ 13,257 (*) As reported in our 2018 Form 10-K dated February 7, 2019. Year Ended December 31, 2017 (In millions) As Previously Reported (*) Adjustments Reclassified Transaction expense $ 4,419 $ — $ 4,419 Transaction and loan losses 1,011 — 1,011 Customer support and operations 1,364 (99 ) 1,265 Sales and marketing 1,128 14 1,142 Product development 953 (953 ) — Technology and development — 1,740 1,740 General and administrative 1,155 103 1,258 Depreciation and amortization 805 (805 ) — Restructuring and other charges 132 — 132 Total operating expenses $ 10,967 $ — $ 10,967 (*) As reported in our 2018 Form 10-K dated February 7, 2019. Use of estimates The preparation of 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 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 and loan losses, loss contingencies, income taxes, revenue recognition, and the valuation of goodwill and intangible assets. We base our estimates on historical experience and various other assumptions which we believe to be reasonable under the circumstances. Actual results could differ from those estimates. Cash and cash equivalents Cash and cash equivalents are short-term, highly liquid investments with original maturities of three months or less when purchased and are composed of primarily bank deposits, government and agency securities, and commercial paper. Investments Short-term investments include time deposits, government and agency securities, and corporate debt securities with original maturities of greater than three months but less than one year when purchased or maturities of less than one year on the reporting date. Long-term investments include government and agency securities and corporate debt securities with maturities exceeding one year, and our strategic investments. Government and agency securities and corporate debt securities 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 estimated tax provisions or benefits. We elect to account for foreign currency denominated available-for-sale investments underlying funds receivable and customer accounts, short-term investments, and long-term investments under the fair value option as further discussed in “Note 9—Fair Value Measurement of Assets and Liabilities.” The changes in fair value related to initial measurement and subsequent changes in fair value are included in earnings as a component of other income (expense), net. Our strategic investments consist of marketable equity securities, which are publicly traded, and non-marketable equity securities, which are investments in privately held companies. Marketable equity securities have readily determinable fair values with changes in fair value recorded in other income (expense), net. Non-marketable equity securities include investments that do not have a readily determinable fair value and equity method investments. The investments that do not have readily determinable fair value are measured at cost minus impairment, if any, adjusted for changes resulting from observable price changes in orderly transactions for an identical or similar investment in the same issuer (the “Measurement Alternative”). All gains and losses on these investments, realized and unrealized, are recognized in other income (expense), net on our consolidated statements of income. Our investments where we have the ability to exercise significant influence, but not control, over the investee are accounted for as equity method investments and our share of the investee’s results of operations is included in other income (expense), net. We assess whether an impairment loss on our non-marketable equity securities and an other-than-temporary impairment loss on our debt securities and equity method investments has occurred due to declines in fair value or other market conditions. If any impairment is identified for non-marketable equity securities or impairment is considered other than temporary for our debt securities and equity method investments, we write down the investment to its fair value and record the corresponding charge through other income (expense), net in our consolidated statements of income. With respect to our debt securities, this assessment takes into account the severity and duration of the decline in value, our intent to sell the security, whether it is more likely than not we will be required to sell the security before recovery of its amortized cost basis, and whether we expect to recover the entire amortized cost basis of the security (that is, whether a credit loss exists). Loans and interest receivable, net Loans and interest receivable, net represents merchant receivables originated under our PayPal Working Capital (“PPWC”) product and PayPal Business Loan (“PPBL”) product and international consumer loans originated under PayPal Credit product. In the U.S., we partner with independent chartered financial institutions that extend credit to the merchant using our PPWC product or PPBL product, and purchase the related receivables extended by the independent chartered financial institutions. For our consumer credit products outside the U.S., we extend credit through our Luxembourg banking subsidiary. For our merchant credit products outside the U.S., we extend working capital advances in the U.K. and loans in Germany through our Luxembourg banking subsidiary, and we extend working capital loans in Australia through an Australian subsidiary. As part of our arrangements with independent chartered financial institutions in the U.S., we sell back a participation interest in the pool of merchant receivables. For these arrangements, gains or losses on the sale of the participation interest are not material as the carrying amount of the participation interest sold approximates the fair value at time of transfer. The independent chartered financial institutions have no recourse against us related to their participation interests for failure of debtors to pay when due. The participation interests held by the chartered financial institutions have the same priority to the interests held by us and are subject to the same credit, prepayment, and interest rate risk associated with this pool of merchant receivables. All risks of loss are shared pro rata based on participation interests held among all participating stakeholders. We apply a control-oriented, financial-components approach and account for the asset transfer as a sale and derecognize the portion of the participation interest for which control has been surrendered. Loans, advances, and interest and fees receivable are reported at their outstanding principal balances, net of any participation interest sold and pro rata allowances, including unamortized deferred origination costs and estimated collectible interest and fees. We maintain the servicing rights for the entire pool of consumer and merchant receivables outstanding and receive a fee approximating the fair value for servicing the assets underlying the participation interest sold. The terms of our consumer relationships require us to submit monthly bills to the consumer detailing loan repayment requirements. The terms also allow us to charge the consumer interest and fees in certain circumstances. Due to the relatively small dollar amount of individual loans and interest receivable, we do not require collateral on these balances. U.S. Consumer Credit Portfolio In November 2017, we reached an agreement to sell our U.S. consumer credit receivables portfolio to Synchrony Bank (“Synchrony”). Following the closing of this transaction in July 2018, Synchrony became the exclusive issuer of the PayPal Credit online consumer financing program in the U.S. We no longer hold an ownership interest in the receivables generated through the program (other than charged off or designated to be charged off receivables) and thus, no longer record these receivables on our consolidated financial statements. PayPal earns a revenue share on the portfolio of consumer receivables owned by Synchrony, which includes both the sold and newly generated receivables, and it is recorded in revenue from other value added services on our consolidated financial statements. See “Note 11—Loans and Interest Receivable” for additional information related to this arrangement. Until the transaction with Synchrony closed, we continued to work with independent chartered financial institutions to extend credit to U.S. consumers using our PayPal Credit product. We purchased the related receivables extended by independent chartered financial institutions until July 2018. As part of the arrangements we had with the independent chartered financial institutions in the U.S., we sold back a participation interest in the pool of U.S. consumer receivables outstanding under PayPal Credit consumer accounts. For these arrangements, gains or losses on the sale of the participation interest were not material as the carrying amount of the participation interest sold approximated the fair value at time of transfer. Allowance for loans and interest receivable The allowance for loans and interest receivable represents management’s estimate of incurred losses inherent in our loans and interest receivables. Increases to the allowance for loans receivables are reflected as a component of transaction and loan losses on our consolidated financial statements. The evaluation process to assess the adequacy of allowances is subject to numerous estimates and principle judgments. For our consumer loans receivable, the allowance is primarily based on forecasted principal balance delinquency rates (“roll rates”). Roll rates are the percentage of balances which we estimate will migrate from one stage of delinquency to the next based on our historical experience, as well as external factors such as estimated bankruptcies and levels of unemployment. Roll rates are applied to the principal amount of our consumer receivables for each stage of delinquency, from current to 180 days past the payment due date, in order to estimate the principal loans which have incurred losses and are probable to be charged off. We charge off consumer loan receivable balances in the month in which a customer’s balance becomes 180 days past the payment due date. In connection with our agreement to sell our U.S. consumer credit receivables to Synchrony and the designation of that portfolio as held for sale, in November 2017, we reversed the corresponding allowances against those loans and interest receivable balances. Such allowances on any newly originated U.S. consumer loans and interest receivables, held for sale were not established. Adjustments to the cost basis of this portfolio until the sale was completed, which were primarily driven by charge-offs, were recorded in restructuring and other charges in our consolidated statements of income. For merchant loans and advances receivable, the allowance is primarily based on principal balances, forecasted delinquency rates, and recoveries through the use of a vintage-based loss forecasting model. The determination of delinquency, from current to 180 days past due, for principal balances related to merchant receivables outstanding is based on the current expected or contractual repayment period of the loan or advance and interest or fixed fee as compared to the original expected or contractual repayment period. For our PPWC product, there is a general requirement that at least 10% of the original amount of the loan or advance plus the fixed fee must be repaid every 90 days. We calculate the repayment rate of the merchant’s future payment volume so that repayment of the loan or advance and fixed fee is expected to generally occur within 9 to 12 months from the date of the loan or advance. On a monthly basis, we recalculate the repayment period based on the repayment activity on the receivable. As such, actual repayment periods are dependent on actual merchant payment processing volumes. For our PPBL product, we receive fixed periodic payments over the contractual term of the loan which generally ranges from 3 to 12 months. We actively monitor receivables with repayment periods greater than the original expected or contractual repayment period. The allowance for loss against interest receivable is primarily determined by applying historical average customer account roll rates to the interest receivable balance in each stage of delinquency to project the value of accounts that have incurred losses and are probable to be charged off. The allowance for fees receivable is primarily based on fee balances, forecasted delinquency rates, and recoveries through the use of a vintage-based loss forecasting model. Increases to the allowance for interest receivable are reflected as a reduction of net revenues in our consolidated statements of income. Increases to the allowance for fees receivable are recognized as a reduction of deferred revenues included in other current liabilities in our consolidated balance sheets. We charge off the receivables under our PPWC product when the repayments are 180 days past our expectation of repayments and the merchant has not made a payment in the last 60 days or when the repayments are 360 days past due regardless of whether the merchant has made a payment within the last 60 days. We charge off the receivables under our PPBL product when the repayments are 180 days past due. Bankrupt accounts are charged off within 60 days for merchants and 90 days for consumers after receipt of notification of bankruptcy. Consumer loans receivable past the payment due date continue to accrue interest until such time as they are charged off. Charge-offs that are recovered are recorded as a reduction to our allowance for loans and interest receivable. Customer accounts We hold all customer balances, both in the U.S. and internationally, as direct claims against us which are reflected on our consolidated balance sheets as a liability classified as amounts due to customers. Certain jurisdictions where PayPal operates require us to hold eligible liquid assets, as defined by applicable regulatory requirements and commercial law in these jurisdictions, equal to at least 100% of the aggregate amount of all customer balances. Therefore, we restrict the use of the assets underlying the customer balances to meet these regulatory requirements and separately classify the assets as customer accounts in our consolidated balance sheets. We classify the assets underlying the customer balances as current based on their purpose and availability to fulfill our direct obligation under amounts due to customers. Customer funds whereby PayPal is an agent and custodian on behalf of our customers are not reflected on our consolidated balance sheet. These funds include U.S. dollar funds which are deposited at one or more third-party financial institutions insured by the Federal Deposit Insurance Corporation (“FDIC”) and are eligible for FDIC pass-through insurance (subject to applicable limits). In June 2018, the Luxembourg Commission de Surveillance du Secteur Financier (the “CSSF”) agreed that PayPal’s management may designate up to 35% of European customer balances held in our Luxembourg banking subsidiary to be used for European and U.S. credit activities. During the year ended December 31, 2019 , an additional amount of $500 million was designated by management to fund such credit activities. As of December 31, 2019 , the cumulative amount approved by management to be designated for credit activities aggregated to $2.0 billion and represented approximately 31% of European customer balances potentially available for corporate use by us at that date as determined by applying financial regulations maintained by the CSSF. On the date PayPal’s management designates the European customer balances held in our Luxembourg banking subsidiary to be used to extend credit, the balances are classified as cash and cash equivalents and no longer classified as customer accounts on our consolidated balance sheets. The remaining assets underlying the customer balances remain separately classified as customer accounts on our consolidated balance sheets. We do not commingle these customer accounts with corporate funds and maintain these assets separately in interest and non-interest bearing bank deposits, time deposits, corporate debt securities, and government and agency securities. See “Note 8—Funds Receivable and Customer Accounts and Investments” for additional information related to customer accounts. We have generally presented changes in funds receivable and customer accounts as cash flows from investing activities in our consolidated statements of cash flows based on the nature of the activity underlying our customer accounts. Funds receivable and funds payable Funds receivable and funds payable arise due to the time required to initiate collection from and clear transactions through external payment networks. When customers fund their PayPal account using their bank account, credit card, debit card, or withdraw funds from their PayPal account to their bank account or through a debit card transaction, there is a clearing period before the cash is received or settled, usually one to three business days for U.S. transactions and generally up to five business days for international transactions. In addition, a portion of our customers’ funds are settled directly to their bank account. These funds are also classified as funds receivable and funds payable and arise due to the time required to initiate collection from and clear transactions through external payment networks. These funds are classified differently on our consolidated statements of cash flows as operating activities based on the nature of this activity. Property and equipment Property and equipment consists primarily of computer equipment, software and website development costs, land and buildings, and leasehold improvements. Property and equipment are stated at historical cost less accumulated depreciation. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets; generally, one to three years for computer equipment and software, including capitalized software and website development costs, three years for furniture and fixtures, up to thirty years for buildings and building improvements, and the shorter of five years or the non-cancelable term of the lease for leasehold improvements. Leases We determine whether an arrangement is a lease for accounting purposes at contract inception. Operating leases are recorded as right-of-use (“ROU”) assets, which are included in other assets, and lease liabilities, which are included in accrued expenses and other liabilities and other long-term liabilities on our consolidated balance sheets. As of December 31, 2019 , we had no finance leases. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Our leases do not provide an implicit rate; we use an incremental borrowing rate for specific terms on a collateralized basis based on the information available on the commencement date in determining the present value of lease payments. The ROU asset calculation includes lease payments to be made and excludes lease incentives. The ROU asset and lease liability may include amounts attributed to options to extend or terminate the lease when it is reasonably certain we will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components. We have elected to apply the practical expedient and account for the lease and non-lease components as a single lease component for all leases. In addition, we have elected the practical expedients related to lease classification, hindsight, and land easement. We apply a single portfolio approach to account for the ROU assets and lease liabilities. Goodwill and intangible assets Goodwill is tested for impairment at a minimum on an annual basis at the reporting unit level by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. If the reporting unit does not pass the qualitative assessment, then the reporting unit’s carrying value is compared to its fair value. Goodwill is considered impaired if the carrying value of the reporting unit exceeds its fair value. The fair value of the reporting unit is estimated using income and market approaches. The discounted cash flow method, a form of the income approach, uses expected future operating results and a market participant discount rate. The market approach uses comparable company prices and other relevant information generated by market transactions (either publicly traded entities or mergers and acquisitions) to develop pricing metrics to be applied to historical and expected future operating results of the reporting unit. Failure to achieve these expected results, changes in the discount rate or market pricing metrics, may cause a future impairment of goodwill at the reporting unit level. We conducted our annual impairment test of goodwill as of August 31, 2019 and 2018 . We determined that no adjustment to the carrying value of goodwill of our reporting unit was required. As of December 31, 2019 , we determined that no events occurred, or circumstances changed from August 31, 2019 through December 31, 2019 that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Intangible assets consist of acquired customer-related intangible assets, marketing related intangibles, developed technology, and other intangible assets. Intangible assets are amortized over the period of estimated benefit using the straight-line method and estimated useful lives ranging from one to eight years . No significant residual value is estimated for intangible assets. Impairment of long-lived assets We evaluate long-lived assets (including intangible assets) for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset may not be recoverable. An asset is considered impaired if its carrying amount exceeds the future net cash flow the asset is expected to generate. Allowance for transaction losses and negative customer balances We are exposed to transaction losses due to credit card and other payment misuse as well as nonperformance of and credit losses from sellers who accept payments through PayPal. We establish an allowance for estimated losses arising from completing customer transactions, such as chargebacks for unauthorized credit card use and merchant-related chargebacks due to non-delivery of goods or services, Automated Clearing House (“ACH”) returns, buyer protection program claims, account takeovers, and account overdrafts. This allowance represents an accumulation of the estimated amounts necessary to provide for transaction losses incurred as of the reporting date, including those which we have not yet identified. The allowance is monitored regularly and is updated based on actual data received, including actual claims data reported by our claims processors. The allowance is based on known facts and circumstances, internal factors including experience with similar cases, historical trends involving loss payment patterns, and the mix of transaction and loss types. Additions to the allowance are reflected as a component of transaction and loan losses in our consolidated statements of income. At December 31, 2019 and 2018 , the allowance for transaction losses totaled $136 million and $129 million , respectively, and was included in accrued expenses and other current liabilities in our consolidated balance sheets. Negative customer balances occur primarily when there are insufficient funds in a customer’s PayPal account to cover charges applied for ACH returns, debit card transactions, and merchant-related chargebacks due to non-delivery or unsatisfactory delivery of goods or services. Negative customer balances can be cured by the customer by adding funds to their account, receiving payments, or through back-up funding sources. We also utilize third-party collection agents. For negative customer balances that are not expected to be cured or otherwise collected, we provide an allowance for uncollectible accounts. The allowance is estimated based on known facts and circumstances, internal factors including our experience with similar cases, and historical trends involving collection and write-off patterns. Negative customer balances are included in other current assets, net of the allowance on our consolidated balance sheets. Adjustments to the allowance for negative customer balances are recorded as a component of transaction and loan losses on our consolidated statements of income. The allowance for negative customer balances was $263 million and $215 million at December 31, 2019 and 2018 , respectively. Derivative instruments See “Note 10—Derivative Instruments” for information related to the derivative instruments. Fair value of financial instruments Our financial assets and liabilities are valued using market prices on both active markets (Level 1) and less active markets (Level 2). Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 instrument valuations are obtained from quoted prices for identical instruments in less active markets, readily available pricing sources for comparable instruments, or models using market observable inputs. As of December 31, 2019 and 2018 , we did not have any assets or liabilities requiring measurement at fair value without observable market values that would require a high level o |
