NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

Note 1 — ACCOUNTING POLICIES
Unaudited Interim Financial Information
We have prepared the accompanying consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting. These consolidated financial statements are unaudited and, in our opinion, include all adjustments, consisting of normal recurring adjustments and accruals necessary for a fair presentation of our consolidated balance sheets, operating results, and cash flows for the periods presented. Operating results for the periods presented are not necessarily indicative of the results that may be expected for 20172018 due to seasonal and other factors. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been omitted in accordance with the rules and regulations of the SEC. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes in Item 8 of Part II, “Financial Statements and Supplementary Data,” of our 20162017 Annual Report on Form 10-K.
Prior Period Reclassifications
Certain prior period amounts have been reclassified to conform to the current period presentation, including the addition of restricted cash to cash and cash equivalents on the consolidated statements of cash flows as a result of the adoption of new accounting guidance.
Principles of Consolidation
The consolidated financial statements include the accounts of Amazon.com, Inc., its wholly-owned subsidiaries, and those entities in which we have a variable interest and of which we are the primary beneficiary, including certain entities in India and China and that support our seller lending financing activities (collectively, the “Company”). Intercompany balances and transactions between consolidated entities are eliminated. The financial results of Whole Foods Market, Inc. (“Whole Foods Market”) have been included in our consolidated financial statements from the date of acquisition on August 28, 2017.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures of contingent liabilities in the consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, determining the selling price of products and services in multiple element revenue arrangements and determining the amortization period of these elements, incentive discount offers, sales returns, vendor funding, stock-based compensation forfeiture rates, income taxes, valuationcommitments and impairment of investments, inventory valuation and inventory purchase commitments, collectability of receivables,contingencies, valuation of acquired intangibles and goodwill, depreciable lives of propertystock-based compensation forfeiture rates, vendor funding, and equipment, internal-use software and website development costs, acquisition purchase price allocations, investments in equity interests, and contingencies.inventory valuation. Actual results could differ materially from those estimates.
Earnings per Share
Basic earnings per share is calculated using our weighted-average outstanding common shares. Diluted earnings per share is calculated using our weighted-average outstanding common shares including the dilutive effect of stock awards as determined under the treasury stock method. In periods when we have a net loss, stock awards are excluded from our calculation of earnings per share as their inclusion would have an antidilutive effect.
The following table shows the calculation of diluted shares (in millions):

Accounting Pronouncements Recently Adopted
In July 2015, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) modifying the accounting for inventory. Under this ASU, the measurement principle for inventory changed from lower of cost or market value to lower of cost and net realizable value. The ASU defines net realizable value as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The ASU is

applicable to inventory thatRevenue
Revenue is accounted for under the first-in, first-out method. We adopted this ASU in Q1 2017 with no material impact to our consolidated financial statements.
In March 2016, the FASB issued an ASU amending the accounting for stock-based compensation and requiring excess tax benefits and deficiencies to be recognized as a component of income tax expense rather than equity. The inclusion of excess tax benefits and deficiencies as a component of our income tax expense will increase volatility within our provision for income taxes asmeasured based on the amount of excess tax benefitsconsideration that we expect to receive, reduced by estimates for return allowances, promotional discounts, and rebates. Revenue also excludes any amounts collected on behalf of third parties, including sales and indirect taxes. In arrangements where we have multiple performance obligations, the transaction price is allocated to each performance obligation using the relative stand-alone selling price. We generally determine stand-alone selling prices based on the prices charged to customers or deficiencies from stock-based compensation awards dependsusing expected cost plus a margin.
A description of our principal revenue generating activities is as follows:
Retail sales - We offer consumer products through our online and physical stores. Revenue is recognized when control of the goods is transferred to the customer, which generally occurs upon our delivery to the carrier or the customer.
Third-party seller services - We offer programs that enable sellers to sell their products on our stock pricewebsites and their own branded websites, and fulfill orders through us. We are not the seller of record in these transactions. The commissions and any related fulfillment and shipping fees we earn from these arrangements are recognized as the services are rendered.
Subscription services - Our subscription sales include fees associated with Amazon Prime memberships and access to content including audiobooks, e-books, digital video, digital music, and other non-AWS subscription services. Prime memberships provide our customers with access to an evolving suite of benefits that represent a single stand-ready obligation. Subscriptions are paid for at the datetime of or in advance of delivering the awards vest. This guidance also requires excess tax benefitsservices. Revenue from such arrangements is recognized over the subscription period.
AWS - Our AWS sales arrangements include global sales of compute, storage, database, and other service offerings. Revenue is allocated to be presentedthe services provided based on stand-alone selling prices and is recognized as an operating activity on the statementservices are rendered. Sales commissions we pay in connection with contracts that exceed one year are capitalized and amortized over the contract term.
Other - Other revenue primarily includes sales of cash flowsadvertising services and allows an entity to make an accounting policy election to either estimate expected forfeitures or to accountis recognized as the services are rendered.
Return Allowances
Return allowances, which reduce revenue and cost of sales, are estimated using historical experience. Liabilities for them as they occur. We adopted this ASUreturn allowances are included in Q1 2017 by recording the cumulative impact through an increase in retained earnings of $687“Accrued expenses and other” and were $468 million and $355 million as of December 31, 2017 and June 30, 2018. Included in “Inventories” on our consolidated balance sheets are assets totaling $406 million and $287 million as of December 31, 2017 and June 30, 2018, for the rights to recover products from customers associated with our liabilities for return allowances.
Cost of Sales
Cost of sales primarily consists of the purchase price of consumer products, digital media content costs, including video and music, packaging supplies, sortation and delivery centers and related equipment costs, and inbound and outbound shipping costs, including where we will continueare the transportation service provider. Shipping costs to estimate expected forfeitures. Additionally, we retrospectively adjustedreceive products from our suppliers are included in our inventory, and recognized as cost of sales upon sale of products to our customers. Payment processing and related transaction costs, including those associated with seller transactions, are classified in “Fulfillment” on our consolidated statements of cash flowsoperations.
Vendor Agreements
We have agreements with our vendors to reclassify excess tax benefitsreceive funds primarily for cooperative marketing efforts, promotions, incentives, and volume rebates. We generally consider these amounts received from vendors to be a reduction of $113 million, $320the prices we pay for their goods, including property and equipment, or services, and are recorded as a reduction of the cost of inventory, cost of services, or cost of property and equipment. Volume rebates typically depend on reaching minimum purchase thresholds. We evaluate the likelihood of reaching purchase thresholds using past experience and current year forecasts. When volume rebates can be reasonably estimated, we record a portion of the rebate as we make progress towards the purchase threshold.
Accounts Receivable, Net and Other
Included in “Accounts receivable, net and other” on our consolidated balance sheets are amounts primarily related to customers, vendors, and sellers. As of December 31, 2017 and June 30, 2018, customer receivables, net, were $6.4 billion and $6.9 billion, vendor receivables, net, were $2.6 billion and $2.2 billion, and seller receivables, net, were $692 million and $323$640 million. Seller receivables are amounts due from sellers related to our seller lending program, which provides funding to sellers primarily to procure inventory.

We estimate losses on receivables based on known troubled accounts and historical experience of losses incurred. Receivables are considered impaired and written-off when it is probable that all contractual payments due will not be collected in accordance with the terms of the agreement. The allowance for doubtful accounts was $348 million forand $403 million as of December 31, 2017 and June 30, 2018.
Unearned Revenue
Unearned revenue is recorded when payments are received or due in advance of performing our service obligations and is recognized over the three months,service period. Unearned revenue primarily relates to prepayments of Amazon Prime memberships and AWS services. Our total unearned revenue as of December 31, 2017 was $6.1 billion, of which $3.9 billion was recognized as revenue during the six months, and twelve months ended June 30, 2016 from financing activities2018, including adjustments related to the new revenue recognition guidance. Included in “Other long-term liabilities” on our consolidated balance sheets was $1.0 billion and $1.2 billion of unearned revenue as of December 31, 2017 and June 30, 2018.
Additionally, we have performance obligations, primarily related to AWS, associated with commitments in customer contracts for future services that have not yet been recognized in our financial statements. For contracts with original terms that exceed one year, the amount of revenue not yet recognized was $16.0 billion as of June 30, 2018. The weighted average remaining life of our long-term contracts is 3.5 years. However, the timing of revenue recognition is largely driven by customer activity, some of which can extend beyond the original contractual term.
Accrued Expenses and Other
Included in “Accrued expenses and other” on our consolidated balance sheets are amounts primarily related to unredeemed gift cards, customer liabilities, leases and asset retirement obligations, current debt, acquired digital media content, and other operating activities.expenses.
As of December 31, 2017 and June 30, 2018, our liabilities for unredeemed gift cards were $3.0 billion and $1.8 billion. We reduce the liability for a gift card when redeemed by a customer. The portion of gift cards that we do not expect to be redeemed is recognized based on customer usage patterns.
Accounting Pronouncements Not YetRecently Adopted
In May 2014, the FASB issued an ASUAccounting Standards Update (“ASU”) amending revenue recognition guidance and requiring more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB deferred the effective date of the revenue recognition guidance to reporting periods beginning after December 15, 2017. Early adoption is permitted for reporting periods beginning after December 15, 2016. As we evaluate the impact ofWe adopted this ASU on January 1, 2018 for all revenue contracts with our customers using the more significant changes that we have identified relatemodified retrospective approach and increased retained earnings by approximately $650 million. The adjustment primarily relates to the timing of when we recognize revenue and the gross amount of revenue that we present. These timing changes will include Amazon-branded electronic devices sold through retailers, which will be recognized upon sale to the retailer rather than to end customers, and the unredeemed portion of our gift cards, which we will begin to recognizeare now recognized over the expected customer redemptionusage period which is substantially within nine months, rather than waiting until gift cards expire or when the likelihood of redemption becomes remote, generally two years fromremote. We changed the daterecognition and classification of issuance. In addition, certainAmazon Prime memberships, which are now accounted for as a single performance obligation and recognized ratably over the membership period as service sales. Previously, Prime memberships were considered to be arrangements with multiple deliverables and were allocated among product sales and service sales. Other changes relate primarily to the presentation of revenue. Certain advertising services will beare now classified as revenue rather than a reduction in cost of sales. Wesales, and sales of apps, in-app content, and certain digital media content are continuing to evaluate thepresented on a net basis.
The impact thatof applying this ASU for the six months ended June 30, 2018 primarily resulted in a decrease in product sales and related amendmentsan increase in service sales driven by a reclassification of Prime membership fees of approximately $1.7 billion, which are now accounted for as a single performance obligation and interpretive guidance, will have on our consolidatedrecognized over the membership period. Service sales also increased by approximately $1.2 billion for the six months ended June 30, 2018 due to the reclassification of certain advertising services that were previously classified as a reduction of cost of sales.
In January 2016, the FASB issued an ASU that updates certain aspects of recognition, measurement, presentation, and disclosure of financial statements, including the related disclosures. We plan to adoptinstruments. Under this ASU, beginningcertain equity investments are measured at fair value with changes recognized in net income. We adopted this ASU in Q1 2018 with no material impact to our consolidated financial statements.
In October 2016, the FASB issued an ASU amending the accounting for income taxes. The new guidance requires the recognition of the income tax consequences of an intercompany asset transfer, other than transfers of inventory, when the transfer occurs. For intercompany transfers of inventory, the income tax effects will continue to be deferred until the inventory has been sold to a cumulative adjustmentthird party. We adopted this ASU in Q1 2018 with an increase of approximately $250 million to retained earnings as opposedand deferred tax assets net of valuation allowances.

In November 2016, the FASB issued an ASU amending the presentation of restricted cash within the consolidated statements of cash flows. The new guidance requires that restricted cash be added to retrospectively adjusting prior periods.cash and cash equivalents on the consolidated statements of cash flows. We adopted this ASU in Q1 2018 on a retrospective basis with the following impacts to our consolidated statements of cash flows (in millions):

Accounting Pronouncements Not Yet Adopted
In February 2016, the FASB issued an ASU amending the accounting for leases. The new guidance requires the recognition of lease assets and liabilities for operating leases with terms of more than 12 months, in addition to those currently recorded, on our consolidated balance sheets. Presentation of leases within the consolidated statements of operations and consolidated statements of cash flows will be generally consistent with the current lease accounting guidance. The ASU is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. We plan to adopt this ASU beginning in Q1 2019. We are currently evaluatingcontinuing to evaluate the impact and expect the ASU will have a material impact on our consolidated financial statements, primarily to the consolidated balance sheets and related disclosures.
In October 2016, the FASB issued an ASU amending the accounting for income taxes. The new guidance requires the recognition of the income tax consequences of an intercompany asset transfer, other than transfers of inventory, when the transfer occurs. For intercompany transfers of inventory, the income tax effects will continue to be deferred until the inventory has been sold to a third party. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. We expect the ASU will have a material impact on our consolidated financial statements, including retained earnings, deferred taxes, and related disclosures. The amount of the impact will depend on results for 2017.
In November 2016, the FASB issued an ASU amending the presentation of restricted cash within the statement of cash flows. The new guidance requires that restricted cash be included within cash and cash equivalents on the statement of cash flows. The ASU is effective retrospectively for reporting periods beginning after December 15, 2017, with early adoption permitted.
Note 2 — CASH, CASH EQUIVALENTS, RESTRICTED CASH, AND MARKETABLE SECURITIES
As of December 31, 2016,2017 and June 30, 2017,2018, our cash, cash equivalents, restricted cash, and marketable securities primarily consisted of cash, U.S. and foreign government and agency securities, AAA-rated money market funds, and other investment grade securities. Cash equivalents and marketable securities are recorded at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs to valuation methodologies used to measure fair value:
Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets.

Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
Level 3—Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.
We measure the fair value of money market funds and equity securities based on quoted prices in active markets for identical assets or liabilities. All other financial instruments were valued either based on recent trades of securities in inactive markets or based on quoted market prices of similar instruments and other significant inputs derived from or corroborated by observable market data. We did not hold any cash, cash equivalents, restricted cash, or marketable securities categorized as Level 3 assets as of December 31, 2016,2017 and June 30, 2017.2018.

Other Contingencies
In 2016, we determined that we processed and delivered orders of consumer products for certain individuals and entities located outside Iran covered by the Iran Threat Reduction and Syria Human Rights Act or other United States sanctions and export control laws. The consumer products included books, music, other media, apparel, home and kitchen, health and beauty, jewelry, office, consumer electronics, software, lawn and patio, grocery, and automotive products. Our review is ongoing and we have voluntarily reported these orders to the United States Treasury Department’s Office of Foreign Assets Control and the United States Department of Commerce’s Bureau of Industry and Security. We intend to cooperate fully with OFAC and BIS with respect to their review, which may result in the imposition of penalties. For additional information, see Item 5 of Part II, “Other Information — Disclosure Pursuant to Section 13(r) of the Exchange Act.”
We are subject to claims related to various indirect taxes (such as sales, value added, consumption, service, and similar taxes), including in jurisdictions in which we already collect and remit such taxes. If the relevant taxing authorities were successfully to pursue these claims, we could be subject to significant additional tax liabilities. For example, in June 2017, the State of South Carolina issued an assessment for uncollected sales and use taxes for the period from January 2016 to March 2016, including interest and penalties. South Carolina is alleging that we should have collected sales and use taxes on transactions by our third-party sellers. We believe the assessment is without merit. If South Carolina or other states were successfully to seek additional adjustments of a similar nature, we could be subject to significant additional tax liabilities. We intend to defend ourselves vigorously in this matter.

20172018 Acquisition Activity
On MayApril 12, 2017,2018, we acquired Souq Group Ltd.Ring Inc. (“Souq”Ring”), an e-commerce company, for cash consideration of approximately $586$853 million, net of cash acquired, to expand our retail presence.product and service offerings. During the six months ended June 30, 2017,2018, we also acquired certain other companies for an aggregate purchase price of $86$39 million. The primary reason for our other 20172018 acquisitions was to acquire

technologies and know-how to enable Amazon to serve customers more effectively.
Acquisition-related costs were expensed as incurred and were not significant. Due to the limited amount of time since the Ring acquisition, of Souq, the valuation of certain assets and liabilities is preliminary and subject to change.

In May 2016,April 2018, we entered into anestablished a commercial paper program (the “Commercial Paper Program”) under which we may from time to time issue unsecured commercial paper up to a total of $7.0 billion at any time, with individual maturities that may vary but will not exceed 397 days from the date of issue. There were no borrowings outstanding under the Commercial Paper Program as of June 30, 2018.

As of June 30, 2017,2018, there was $6.6$7.6 billion of net unrecognized compensation cost related to unvested stock-based compensation arrangements. This compensation is recognized on an accelerated basis with approximately half of the compensation expected to be expensed in the next twelve months, and has a weighted-average recognition period of 1.21.1 years. The estimated forfeiture rate as of December 31, 20162017 and June 30, 2017,2018 was 28% and 27%. Changes in our estimates and assumptions relating to forfeitures may cause us to realize material changes in stock-based compensation expense in the future.
Note 7 — INCOME TAXES
Our tax provision or benefit from income taxes for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter we update our estimate of the annual effective tax rate, and if our estimated tax rate changes, we make a cumulative adjustment.
Our quarterly tax provision, and our quarterly estimate of our annual effective tax rate, is subject to significant variation due to several factors, including variability in accurately predicting our pre-tax and taxable income and loss and the mix of jurisdictions to which they relate, intercompany transactions, the applicability of special tax regimes, changes in how we do business, acquisitions (including integrations) and investments, audit-related developments, changes in our stock price, changes in our deferred tax assets and liabilities and their valuation, foreign currency gains (losses), tax law developments (including changes in statutes, regulations, case law, and administrative practices),practices, principles, and interpretations related to tax, accounting, and other areas, including European Union state aid rules, and relative changes of expenses or losses for which tax benefits are not recognized. Additionally, our effective tax rate can be more or less volatile based on the amount of pre-tax income or loss. For example, the impact of discrete items and non-deductible expenses on our effective tax rate is greater when our pre-tax income is lower.
The 2017 Tax Act was signed into law on December 22, 2017. The 2017 Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering the statutory corporate tax rate from 35% to 21%, eliminating certain deductions, imposing a mandatory one-time tax on accumulated earnings of foreign subsidiaries, introducing new tax regimes, and changing how foreign earnings are subject to U.S. tax. The 2017 Tax Act also enhanced and extended through 2026 the option to claim accelerated depreciation deductions on qualified property. We have not completed our determination of the accounting implications of the 2017 Tax Act on our tax accruals. However, we reasonably estimated the effects of the 2017 Tax Act and recorded provisional amounts in our financial statements as of December 31, 2017. We recorded a provisional tax benefit for the impact of the 2017 Tax Act of approximately $789 million. This amount was primarily comprised of the remeasurement of federal net deferred tax liabilities resulting from the permanent reduction in the U.S. statutory corporate tax rate to 21% from 35%, after taking into account the mandatory one-time tax on the accumulated earnings of our foreign subsidiaries. The amount of this one-time tax is not material. As we complete our analysis of the 2017 Tax Act, collect and prepare necessary data, and interpret any additional guidance issued by the U.S. Treasury Department, the IRS, and other standard-setting bodies, we may make adjustments to the provisional amounts. Those adjustments may materially impact our provision for income taxes in the period in which the adjustments are made.
For 2017,2018, we estimate that our effective tax rate will be favorably affected by the impact of excess tax benefits from stock-based compensation and the U.S. federal research and development credit and adversely affected by the recordinglosses incurred in certain foreign jurisdictions for which we may not realize a tax benefit. Losses for which we may not realize a related tax benefit, primarily due to losses of foreign subsidiaries, reduce our pre-tax income without a corresponding reduction in our tax expense, and therefore increase our effective tax rate. We record valuation allowances against the deferred tax assets associated with losses for which we may not realize a related to net operating losses generated in Luxembourg and state income taxes.tax benefit.
Our income tax provision for the six months ended June 30, 2016 was $782 million, which included $70 million of discrete tax benefits primarily attributable to audit-related and tax law developments. Our income tax provision for the six months ended June 30, 2017 was $695 million, which included $197 million of net discrete tax benefits primarily attributable to excess tax benefits from stock-based compensation, partially offset by a valuation allowance we recorded against the deferred tax assets related to net operating losses generated in Luxembourg and the estimated impact of audit-related developments.
We regularly assess whether it is more likely than not that we will realize our deferred Our income tax assets in each taxing jurisdiction inprovision for the six months ended June 30, 2018 was $361 million, which we operate. In performing this assessment with respectincluded $964 million of net discrete tax benefits primarily attributable to each jurisdiction, we review all available evidence, including recent cumulative loss experience and expectations of future earnings, capital gains, and investment in such jurisdiction, the carry-forward periods available to us forexcess tax reporting purposes, and other relevant factors. In Q2 2017, we recognized an estimated charge to tax expense of $600 million to record a valuation allowance against the net deferred tax assets in Luxembourg.benefits from stock-based compensation.
Cash paid for income taxes, net of refunds was $88$447 million and $447$300 million in Q2 20162017 and Q2 2017,2018, and $226$693 million and $693$813 million for the six months ended June 30, 20162017 and 2017.2018.
As of December 31, 2016,2017 and June 30, 2017,2018, tax contingencies were approximately $1.72.3 billion and $1.9$3.3 billion. We expect the total amount of tax contingencies will grow in 2017.2018. In addition, changes in state, federal, and foreign tax laws may increase our tax contingencies. The timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ from the amounts accrued. It is reasonably possible that within the next 12 months we will receive additional assessments by various tax authorities or possibly reach resolution of income tax examinations in one or more jurisdictions. These assessments or settlements could result in changes to our contingencies related to positions on tax filings on prior years’ tax filings.
We are under examination, or may be subject to examination, by the Internal Revenue Service (“IRS”) for the calendar year 2005 and thereafter. These examinations may lead to ordinary course adjustments or proposed adjustments to our taxes or

our net operating losses with respect to years under examination as well as subsequent periods. As previously disclosed, we have received Notices of Proposed Adjustment (“NOPAs”) from the IRS for transactions undertaken in the 2005 and 2006

calendar years relating to transfer pricing with our foreign subsidiaries. The IRS is seeking to increase our U.S. taxable income by an amount that would result in additional federal tax of approximately $1.5 billion, subject to interest. On March 23, 2017, the U.S. Tax Court issued its decision regarding the issues raised in the IRS NOPAs. The Tax Court rejected the approach from the IRS NOPAs in determining transfer pricing adjustments in 2005 and 2006 for the transactions undertaken with our foreign subsidiaries and adopted, with adjustments, our suggested approach. TheIn September 2017, the IRS appealed the decision is subject to appeal.the U.S. Court of Appeals for the Ninth Circuit. We will continue to defend ourselves vigorously in this matter. If the Tax Court decision were reversed on appeal or if the IRS were to successfully assert transfer pricing adjustments of a similar nature to the NOPAs for transactions in subsequent years, we could be subject to significant additional tax liabilities.
Certain of our subsidiaries are under examination or investigation or may be subject to examination or investigation by the French Tax Administration (“FTA”) for calendar year 2006 and thereafter. These examinations may lead to ordinary course adjustments or proposed adjustments to our taxes. In September 2012, we received proposed tax assessment notices for calendar years 2006 through 2010 relating to the allocation of income between foreign jurisdictions. In June 2015, we received final tax collection notices for these years assessing additional French tax of €196 million, including interest and penalties through September 2012. We disagree with the assessment and intend to contest it vigorously. We plan to pursue all available administrative remedies, and if we are not able to resolve this matter, we plan to pursue judicial remedies. In addition to the risk of additional tax for years 2006 through 2010, if this litigation is adversely determined or if the FTA were to seek adjustments of a similar nature for subsequent years, we could be subject to significant additional tax liabilities. In addition, in October 2014, the European Commission opened a formal investigation to examine whether decisions by the tax authorities in Luxembourg with regard to the corporate income tax paid by certain of our subsidiaries comply with European Union rules on state aid. IfOn October 4, 2017, the European Commission announced its decision that determinations by the tax authorities in Luxembourg did not comply with European Union rules on state aid. Based on that decision the European Commission announced an estimated recovery amount of approximately €250 million, plus interest, for the period May 2006 through June 2014, and ordered Luxembourg tax authorities to calculate the actual amount of additional taxes subject to recovery. Luxembourg computed an initial recovery amount, consistent with the European Commission’s decision, that we deposited into escrow in March 2018, subject to adjustment pending conclusion of all appeals. In December 2017, Luxembourg appealed the European Commission’s decision. In May 2018, we appealed. We believe the European Commission’s decision to be without merit and will continue to defend ourselves vigorously in this matter is adversely resolved, Luxembourg may be required to assess, and we may be required to pay, additional amounts with respect to current and prior periods from 2003 onwards and our taxes in the future could increase.matter. We are also subject to taxation in various states and other foreign jurisdictions including Canada, China, Germany, India, Italy, Japan, Luxembourg, and the United Kingdom. We are under, or may be subject to, audit or examination and additional assessments by the relevant authorities in respect of these particular jurisdictions primarily for 2008 and thereafter.
Note 8 — SEGMENT INFORMATION
We have organized our operations into three segments: North America, International, and AWS. We allocate to segment results the operating expenses “Fulfillment,” “Marketing,” “Technology and content,” and “General and administrative” based on usage, which is generally reflected in the segment in which the costs are incurred. The majority of technology infrastructure costs are allocated to the AWS segment based on usage. The majority of the remaining non-infrastructure technology costs are incurred in the U.S. and are allocated to our North America segment. In Q1 2017, we combined stock-based compensation and “Other operating expense, net” with operating expensesThe results of Whole Foods Market are included in our presentation of segment results.North America and International segments based on physical location. There are no internal revenue transactions between our reportable segments. These segments reflect the way our chief operating decision maker evaluates the Company’s business performance and manages its operations.
North America
The North America segment primarily consists of amounts earned from retail sales of consumer products (including from sellers) and subscriptions through North America-focused websites such as www.amazon.com, www.amazon.ca, and www.amazon.com.mx.physical stores. This segment includes export sales from these websites.
International
The International segment primarily consists of amounts earned from retail sales of consumer products (including from sellers) and subscriptions through internationally-focused websites such as www.amazon.com.au, www.amazon.com.br, www.amazon.cn, www.amazon.fr, www.amazon.de, www.amazon.in, www.amazon.it, www.amazon.co.jp, www.amazon.nl, www.amazon.es, and www.amazon.co.uk.websites. This segment includes export sales from these internationally-focused websites (including export sales from these sites to customers in the U.S., Mexico, and Canada), but excludes export sales from our North AmericanAmerica-focused websites.
AWS
The AWS segment consists of amounts earned from global sales of compute, storage, database, and other service offerings for start-ups, enterprises, government agencies, and academic institutions.

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations
Forward-Looking Statements
This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact, including statements regarding guidance, industry prospects, or future results of operations or financial position, made in this Quarterly Report on Form 10-Q are forward-looking. We use words such as anticipates, believes, expects, future, intends, and similar expressions to identify forward-looking statements. Forward-looking statements reflect management’s current expectations and are inherently uncertain. Actual results could differ materially for a variety of reasons, including, among others, fluctuations in foreign exchange rates, changes in global economic conditions and customer spending, world events, the rate of growth of the Internet, online commerce, and cloud services, the amount that Amazon.com invests in new business opportunities and the timing of those investments, the mix of products and services sold to customers, the mix of net sales derived from products as compared with services, the extent to which we owe income or other taxes, competition, management of growth, potential fluctuations in operating results, international growth and expansion, the outcomes of legal proceedings and claims, fulfillment, sortation, delivery, and data center optimization, risks of inventory management, seasonality, the degree to which we enter into, maintain, and develop commercial agreements, proposed and completed acquisitions and strategic transactions, payments risks, and risks of fulfillment throughput and productivity. In addition, the current global economic climate amplifies many of these risks. These risks and uncertainties, as well as other risks and uncertainties that could cause our actual results to differ significantly from management’s expectations, are described in greater detail in Item 1A of Part II, “Risk Factors.”
For additional information, see Item 7 of Part II, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Overview” of our 20162017 Annual Report on Form 10-K.
Critical Accounting Judgments
The preparation of financial statements in conformity with GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities in the consolidated financial statements and accompanying notes. The SEC has defined a company’s critical accounting policies as the ones that are most important to the portrayal of the company’s financial condition and results of operations, and which require the company to make its most difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Based on this definition, we have identified the critical accounting policies and judgments addressed below. We also have other key accounting policies, which involve the use of estimates, judgments, and assumptions that are significant to understanding our results. For additional information, see Item 8 of Part II, “Financial Statements and Supplementary Data — Note 1 — Description of Business and Accounting Policies,” of our 20162017 Annual Report on Form 10-K and Item 1 of Part I, “Financial Statements — Note 1 — Accounting Policies,” of this Form 10-Q. Although we believe that our estimates, assumptions, and judgments are reasonable, they are based upon information presently available. Actual results may differ significantly from these estimates under different assumptions, judgments, or conditions.
Inventories
Inventories, consisting of products available for sale, are primarily accounted for using the first-in first-out method, and are valued at the lower of cost and net realizable value. This valuation requires us to make judgments, based on currently-available information, about the likely method of disposition, such as through sales to individual customers, returns to product vendors, or liquidations, and expected recoverable values of each disposition category. These assumptions about future disposition of inventory are inherently uncertain and changes in our estimates and assumptions may cause us to realize material write-downs in the future. As a measure of sensitivity, for every 1% of additional inventory valuation allowance as of June 30, 2017,2018, we would have recorded an additional cost of sales of approximately $130$160 million.
In addition, we enter into supplier commitments for certain electronic device components.components and certain products. These commitments are based on forecasted customer demand. If we reduce these commitments, we may incur additional costs.
Income Taxes
We are subject to income taxes in the U.S. (federal and state) and numerous foreign jurisdictions. Tax laws, regulations, and administrative practices in various jurisdictions may be subject to significant change, with or without notice, due to economic, political, and other conditions, and significant judgment is required in evaluating and estimating our provision and accruals for these taxes. There are many transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. Our effective tax rates could be affected by numerous factors, such as intercompany transactions, the relative amount of our foreign earnings, including earnings being lower than anticipated in jurisdictions where we have lower statutory rates and higher than anticipated in jurisdictions where we have higher statutory rates, the applicability

of special tax regimes, losses incurred in jurisdictions for which we are not able to realize the related tax benefit, changes in foreign currency exchange rates,

entry into new businesses and geographies, and changes to our existing businesses and operations, acquisitions (including integrations) and investments and how they are financed, changes in our stock price, changes in our deferred tax assets and liabilities and their valuation, and changes in the relevant tax, accounting, and other laws, regulations, administrative practices, principles, and interpretations related to tax, accounting, and other areas, including fundamentalEuropean Union state aid rules. In addition, a number of countries are actively pursuing changes to thetheir tax laws applicable to corporate multinationals.multinationals, such as the recently enacted U.S. tax reform legislation commonly referred to as the U.S. Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”). Finally, foreign governments may enact tax laws in response to the 2017 Tax Act that could result in further changes to global taxation and materially affect our financial position and results of operations.
The 2017 Tax Act significantly changes how the U.S. taxes corporations. The 2017 Tax Act requires complex computations to be performed that were not previously required in U.S. tax law, significant judgments to be made in interpretation of the provisions of the 2017 Tax Act and significant estimates in calculations, and the preparation and analysis of information not previously relevant or regularly produced. The U.S., Treasury Department, the European UnionIRS, and its member states, and a number of other countries are actively pursuing changes in this regard.
Except as required under U.S. tax laws, we do not provide for U.S. taxesstandard-setting bodies could interpret or issue guidance on our undistributed earnings of foreign subsidiaries that have not been previously taxed since we intend to invest such undistributed earnings indefinitely outsidehow provisions of the U.S. If2017 Tax Act will be applied or otherwise administered that is different from our intent changes or if these fundsinterpretation. As we complete our analysis of the 2017 Tax Act, collect and prepare necessary data, and interpret any additional guidance, we may make adjustments to provisional amounts that we have recorded that may materially impact our provision for income taxes in the period in which the adjustments are needed for our U.S. operations, we would be required to accrue or pay U.S. taxes on some or all of these undistributed earnings and our effective tax rate would be adversely affected. made.
We are also currently subject to audit in various jurisdictions, and these jurisdictions may assess additional income tax liabilities against us. Developments in an audit, litigation, or the relevant laws, regulations, administrative practices, principles, and interpretations could have a material effect on our operating results or cash flows in the period or periods for which that development occurs, as well as for prior and subsequent periods. For instance, the IRS is seeking to increase our U.S. taxable income related to transfer pricing with our foreign subsidiaries for transactions undertaken in 2005 and 2006, and we have been contesting the matter in U.S. Tax Court. On March 23, 2017, the U.S. Tax Court issued its decision regarding the issues raised in the IRS Notices of Proposed Adjustment (“NOPAs”). The Tax Court rejected the approach from the IRS NOPAs in determining transfer pricing adjustments in 2005 and 2006 for the transactions undertaken with our foreign subsidiaries and adopted, with adjustments, our suggested approach. The decision is subject to appeal. If the Tax Court decision were reversed on appeal or if the IRS were to successfully assert transfer pricing adjustments of a similar nature to the NOPAs for transactions in subsequent years, we could be subject to significant additional tax liabilities. In addition, in October 2014, the European Commission opened a formal investigation to examine whether decisions by the tax authorities in Luxembourg with regard to the corporate income tax paid by certain of our subsidiaries comply with European Union rules on state aid. If this matter is adversely resolved, Luxembourg may be required to assess, and we may be required to pay, additional amounts with respect to current and prior periods and our taxes in the future could increase. Although we believe our tax estimates are reasonable, the final outcome of tax audits, investigations, and any related litigation could be materially different from our historical income tax provisions and accruals.

Our principal sources of liquidity are cash flows generated from operations and our cash, cash equivalents, and marketable securities balances, which, at fair value, were $26.0$31.0 billion and $21.5$27.1 billion as of December 31, 2016,2017 and June 30, 2017.2018. Amounts held in foreign currencies were $9.1$11.1 billion and $7.3$7.9 billion as of December 31, 2016,2017 and June 30, 2017,2018, and were primarily Euros, Japanese Yen, and British Pounds.
Cash provided by (used in) operating activities was $3.6$3.9 billion and $3.8$7.4 billion for Q2 20162017 and Q2 2017,2018, and $1.6$2.2 billion and $2.2$5.7 billion for the six months ended June 30, 20162017 and 2017.2018. Our operating cash flows result primarily from cash received from our consumer, seller, developer, enterprise, and content creator customers, advertising agreements, and our co-branded credit cardadvertising agreements, offset by cash payments we make for products and services, employee compensation (less amounts capitalized related to internal-use software that are reflected as cash used in investing activities), payment processing and related transaction costs, operating leases, and interest payments on our long-term obligations. Cash received from our customers and other activities generally corresponds to our net sales. Because consumers primarily use credit cards to buy from us, our receivables from consumers settle quickly. The increase in operating cash flow for the trailing twelve months ended June 30, 2017,2018, compared to the comparable prior year period, was primarily due to the increase in net income, excluding non-cash charges such as depreciation, amortization, and stock-based compensation. Cash provided by (used in) operating activities is also subject to changes in working capital. Working capital at any specific point in time is subject to many variables, including seasonality, inventory management and category expansion, the timing of cash receipts and payments, vendor payment terms, and fluctuations in foreign exchange rates.
Cash provided by (used in) investing activities corresponds with cash capital expenditures, including leasehold improvements, internal-use software and website development costs, cash outlays for acquisitions, investments in other companiesincentives received from property and equipment vendors, intellectual property rights, and purchases, sales, and maturities of marketable securities. Cash provided by (used in) investing activities was $(2.4)$(5.3) billion and $(5.1)$(2.7) billion for Q2 20162017 and Q2 2017,2018, and $(3.1)$(6.6) billion and $(6.7)$(3.2) billion for the six months ended June 30, 20162017 and 2017,2018, with the variability caused primarily by our decision to purchase or lease property and equipment, and purchases, maturities, and sales of marketable securities, and changes in cash paid for acquisitions.securities. Cash capital expenditures were $1.7$2.5 billion and $2.5$2.9 billion during Q2 20162017 and Q2 2017,2018, and $2.9$4.4 billion and $4.4$5.7 billion for the six months ended June 30, 20162017 and 2017,2018, which primarily reflect additional capacity to support our fulfillment operations and additional investments in support of continued business growth due to investments in technology infrastructure (the majority of which is to support AWS). Capital expenditures included $118$90 million and $90$58 million for internal-use software and website development during Q2 20162017 and Q2 2017,2018, and $229$164 million and $164$118 million for the six months ended June 30, 20162017 and 2017.2018. Stock-based compensation capitalized for internal-use software and website development costs does not affect cash flows. We made cash payments, net of acquired cash, related to acquisition and other investment activity of $14$633 million and $633866 million during Q2 20162017 and Q2 2017,2018, and $30$678 million and $678$879 million for the six months ended June 30, 20162017 and 2017.2018.
Cash provided by (used in) financing activities was $(1.2)$(1.3) billion and $(1.3)$(1.4) billion for Q2 20162017 and Q2 2017,2018, and $(2.1)$(2.2) billion and $(2.2)$(3.6) billion for the six months ended June 30, 20162017 and 2017.2018. Cash outflows from financing activities result from principal repayments on obligations related to capital leases and finance leases and repayments of long-term debt and other. Principal repayments on obligations related to capital leases and finance leases and repayments of long-term debt and other, which were $1.2$1.3 billion and $1.3$1.5 billion in Q2 20162017 and Q2 2017,2018, and $2.2 billion and $2.3$3.8 billion for the six months ended June 30, 20162017 and 2017.2018. Property and equipment acquired under capital leases was $1.4$2.7 billion and $2.7$2.3 billion during Q2 20162017 and Q2 2017, and $2.3 billion2018, and $4.6 billion for the six months ended June 30, 20162017 and 2017,2018, reflecting investments in support of continued business growth primarily due to investments in technology infrastructure for AWS, which investments we expect to continue over time. Cash inflows from financing activities primarily result from proceeds from long-term debt and other. Proceeds from long-term debt and other were $66$49 million and $66$96 million in Q2 20162017 and Q2 2017,2018, and $75$70 million and $90$221 million for the six months ended June 30, 20162017 and 2017.2018.
In April 2018, we established a commercial paper program (the “Commercial Paper Program”) under which we may from time to time issue unsecured commercial paper up to a total of $7.0 billion at any time, with individual maturities that may vary but will not exceed 397 days from the date of issue. There were no borrowings outstanding under the Commercial Paper Program as of June 30, 2018.

We had no borrowings outstanding under ourthe Credit Agreement and $500$489 million of borrowings outstanding under our Credit Facility as of June 30, 2017.2018. See Item 1 of Part I, “Financial Statements — Note 5 — Long-Term Debt” for additional information.

In June 2017, we entered into a commitment letter (the “Commitment Letter”) with Goldman Sachs Bank USA, Goldman Sachs Lending Partners LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, and Bank of America, N.A. (collectively, the “Commitment Parties”), pursuant to which, subject to the terms and conditions set forth therein, the Commitment Parties have committed to provide a 364-day senior unsecured bridge term loan facility in an aggregate principal amount of up to $13.7 billion (the “Bridge Facility”), to fund the consideration for the acquisition of Whole Foods Market, Inc. To the extent we obtain funding for the acquisition by issuing debt securities or obtaining other loans, the availability of the Bridge Facility is correspondingly reduced. The funding of the Bridge Facility provided for in the Commitment Letter is contingent on the satisfaction of customary conditions, including (i) the execution and delivery of definitive documentation with respect to the Bridge Facility in accordance with the terms sets forth in the Commitment Letter, and (ii) the consummation of the acquisition of Whole Foods Market, Inc.
We recorded net tax provisions of $307$467 million and $467$74 million in Q2 20162017 and Q2 2017,2018, and $782$695 million and $695$361 million for the six months ended June 30, 20162017 and 2017. Except as required under U.S.2018. The 2017 Tax Act includes a mandatory one-time tax laws, we do not provide for U.S. taxes on our undistributedaccumulated earnings of foreign subsidiaries, thatand as a result, all previously unremitted earnings for which no U.S. deferred tax liability had been accrued have notnow been previously taxed sincesubject to U.S. tax. Notwithstanding the U.S. taxation of these amounts, we intend to continue to invest such undistributedmost or all of these earnings, as well as our capital in these subsidiaries, indefinitely outside of the U.S. If our intent changes or if these funds are needed for our U.S. operations, we would be requiredand do not expect to accrue or pay U.S.incur any significant, additional taxes on some or all of these undistributed earnings, and our effective tax rate would be adversely affected. related to such amounts.
We have tax benefits relating to excess stock-based compensation deductions and accelerated depreciation deductions that are being utilized to reduce our U.S. taxable income. In December 2015, U.S. legislation was enacted thatThe 2017 Tax Act extended through 2026 and enhanced the option to claim accelerated depreciation deductions on qualifying property through 2019.property. Cash taxes paid net(net of refundsrefunds) were $88$447 million and $447$300 million for Q2 20162017 and Q2 2017,2018, and $226$693 million and $693$813 million for the six months ended June 30, 20162017 and 2017.2018. As of December 31, 2016,2017, our federal net operating loss carryforward was approximately $76$226 million and we had approximately $608$855 million of federal tax credits potentially available to offset future tax liabilities. Our federal tax credits are primarily related to the U.S. federal research and development credit. WeAs we utilize our federal net operating losses and tax credits we expect cash paid for taxes to increase. We endeavor to manage our global taxes on a cash basis, rather than on a financial reporting basis. In connection with the European Commission’s October 2017 decision against us on state aid, Luxembourg computed an initial recovery amount, consistent with the European Commission’s decision, of approximately €250 million, that we deposited into escrow in March 2018, subject to adjustment pending conclusion of all appeals.
Our liquidity is also affected by restricted cash balances that are pledged as collateral for real estate leases, amounts due to third-party sellers in certain jurisdictions, debt, and standby and trade letters of credit, guarantees, debt, and real estate leases.credit. To the extent we process payments for third-party sellers or offer certain types of stored value to our customers, some jurisdictions may restrict our use of those funds. These restrictions would result in the reclassification of a portion of our cash and cash equivalents from “Cash and cash equivalents” to restricted cash, which is classified within “Accounts receivable, net and other” on our consolidated balance sheets. As of December 31, 2016,2017 and June 30, 2017,2018, restricted cash, cash equivalents, and marketable securities were $600 million$1.3 billion and $648$716 million. See Item 1 of Part I, “Financial Statements — Note 3 — Commitments and Contingencies” for additional discussion of our principal contractual commitments, as well as our pledged assets. PurchaseAdditionally, purchase obligations and open purchase orders, consisting of inventory and significant non-inventory commitments, were $12.9$14.4 billion as of June 30, 2017. Purchase2018. These purchase obligations and open purchase orders are generally cancellable in full or in part through the contractual provisions.
We expect to fund the acquisition of Whole Foods Market, Inc. with debt financing together with cash on hand. We believe that cash flows generated from operations and our cash, cash equivalents, and marketable securities balances, as well as our borrowing available under our credit agreements,arrangements, will be sufficient to meet our anticipated operating cash needs for at least the next 12 months. However, any projections of future cash needs and cash flows are subject to substantial uncertainty. See Item 1A of Part II, “Risk Factors.” We continually evaluate opportunities to sell additional equity or debt securities, obtain credit facilities, obtain capital, finance, and operating lease arrangements, repurchase common stock, pay dividends, or repurchase, refinance, or otherwise restructure our debt for strategic reasons or to further strengthen our financial position.
The sale of additional equity or convertible debt securities would likely be dilutive to our shareholders. In addition, we will, from time to time, consider the acquisition of, or investment in, complementary businesses, products, services, capital infrastructure, and technologies, which might affect our liquidity requirements or cause us to secure additional financing, or issue additional equity or debt securities. There can be no assurance that additional credit lines or financing instruments will be available in amounts or on terms acceptable to us, if at all.






Results of Operations
We have organized our operations into three segments: North America, International, and AWS. In Q1 2017, we combined stock-based compensation and “Other operating expense, net” with operating expensesOur results reflect the operations of Whole Foods Market from the date of acquisition in our presentation of segment results.August 2017. These segments reflect the way the Company evaluates its business performance and manages its operations. See Item 1 of Part I, “Financial Statements — Note 8 — Segment Information.”
Net Sales
Net sales include product and service sales. Product sales represent revenue from the sale of retail products and related shipping fees and digital media content where we record revenue gross. Service sales primarily represent retail third-party seller fees earned (including commissions) and related shipping fees, AWS sales, certain digital content subscriptions, certain advertising services, and our co-branded credit card agreements. Amazon Prime membership fees, are allocated between product salesadvertising services, and service sales and amortized over the life of the membership according to the estimated delivery of services.certain digital content subscriptions.

Cost of Sales
Cost of sales primarily consists of the purchase price of consumer products, digital media content costs where we record revenue gross, including Prime Videovideo and Prime Music,music, packaging supplies, sortation and delivery centerscenter and related equipment costs, and inbound and outbound shipping costs, including where we are the transportation service provider.
The increase in cost of sales in absolute dollars in Q2 20172018 and for the six months ended June 30, 2017,2018, compared to the comparable prior year periods, is primarily due to increased product and shipping costs resulting from increased sales.
Shipping costs to receive products from our suppliers are included in our inventory and recognized as cost of sales upon sale of products to our customers. Shipping costs, which include sortation and delivery center and transportation costs, were $3.4$4.6 billion and $4.6$6.0 billion in Q2 20162017 and Q2 2017,2018, and $6.6$9.0 billion and $9.0$12.1 billion for the six months ended June 30, 20162017 and 2017.2018. We expect our cost of shipping to continue to increase to the extent our customers accept and use our shipping offers at an increasing rate, we reduce shipping rates, we use more expensive shipping methods, and we offer additional services. We seek to mitigate costs of shipping over time in part through achieving higher sales volumes, optimizing our fulfillment network, negotiating better terms with our suppliers, and achieving better operating efficiencies. We believe that offering low prices to our customers is fundamental to our future success, and one way we offer lower prices is through shipping offers.
Costs to operate our AWS segment are primarily classified as “Technology and content” as we leverage a shared infrastructure that supports both our internal technology requirements and external sales to AWS customers.
Fulfillment
Fulfillment costs primarily consist of those costs incurred in operating and staffing our North America and International fulfillment andcenters, customer service centers, and physical stores and payment processing costs. While AWS payment processing and related transaction costs are included in fulfillment, AWS costs are primarily classified as “Technology and content.” Fulfillment costs as a percentage

of net sales may vary due to several factors, such as payment processing and related transaction

costs, our level of productivity and accuracy, changes in volume, size, and weight of units received and fulfilled, timing of fulfillment network and physical store expansion, the extent we utilize fulfillment services provided by third parties, mix of products and services sold, and our ability to affect customer service contacts per unit by implementing improvements in our operations and enhancements to our customer self-service features. Additionally, because payment processing and fulfillment costs associated with seller transactions are based on the gross purchase price of underlying transactions, and payment processing and related transaction and fulfillment costs are higher as a percentage of sales versus our retail sales, sales by our sellers have higher fulfillment costs as a percent of net sales.
The increase in fulfillment costs in absolute dollars in Q2 20172018 and for the six months ended June 30, 2017,2018, compared to the comparable prior year periods, is primarily due to variable costs corresponding with increased product and service sales volume and inventory levels, and costs from expanding our fulfillment network.network, which includes physical stores.
We seek to expand our fulfillment capacitynetwork to accommodate a greater selection and in-stock inventory levels and to meet anticipated shipment volumes from sales of our own products as well as sales by third parties for which we provide the fulfillment services. We regularly evaluate our facility requirements.
Marketing
We direct customers to our websites primarily through a number of targeted online marketing channels, such as our sponsored search, Associates program, sponsored search, social and online advertising, television advertising, and other initiatives. Our marketing costs are largely variable, based on growth in sales and changes in rates. To the extent there is increased or decreased competition for these traffic sources, or to the extent our mix of these channels shifts, we would expect to see a corresponding change in our marketing costs.
The increase in marketing costs in absolute dollars in Q2 20172018 and for the six months ended June 30, 2017,2018, compared to the comparable prior year periods, is primarily due to payroll and related expenses, as well as increased spending on online marketing channels.
While costs associated with Amazon Prime memberships and other shipping offers are not included in marketing expense, we view these offers as effective worldwide marketing tools, and intend to continue offering them indefinitely.
Technology and Content
Technology and content costs consist principally of research and development activities includinginclude payroll and related expenses for employees involved in application, production, maintenance, operation,the research and development of new and existing products and services, development, design, and maintenance of our websites, curation and display of products and services made available on our websites, and infrastructure costs. Infrastructure costs include servers, networking equipment, and data center related depreciation, rent, utilities, and other expenses necessary to support AWS, as well as AWSthese and other technology infrastructure costs. Contentefforts. Collectively, these costs consist principallyreflect the investments we make in order to offer a wide variety of payrollproducts and related expenses for employees involved in category expansion, editorial content, buying, and merchandising selection.services to our customers.
We seek to invest efficiently in severalnumerous areas of technology and content so we may continue to enhance the customer experience and improve our process efficiency through rapid technology developments, while operating at an ever increasing scale. Our technology and content investment and capital spending projects often support a variety of product and service offerings due to geographic expansion and the cross-functionality of our systems and operations. We expect spending in technology and content to increase over time as we continue to add employees and technology infrastructure. These costs are allocated to segments based on usage. The increase in technology and content costs in absolute dollars in Q2 20172018 and for the six months ended June 30, 2017,2018, compared to the comparable prior year periods, is primarily due to increased payroll and related costs associated with technical teams responsible for expanding our existing products and services and initiatives to introduce new products and service offerings, and an increase in spending on technology infrastructure.
Technology infrastructure costs consist of servers, networking equipment, and data center related depreciation, rent, utilities, and payroll expenses. These costs are allocated to segments based on usage. During Q2 2017, we expanded our technology infrastructure principally by increasing our capacity for AWS service offerings globally, compared to the comparable prior year period. Additionally, the costs associated with operating and maintaining our expanded infrastructure have increased over time, corresponding with increased usage. We expect these trends to continue over time as we invest in technology infrastructure to support increased usage. See Item 7 of Part II, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Overview” of our 20162017 Annual Report on Form 10-K for a discussion of how management views advances in technology and the importance of innovation.
During Q2 20162017 and Q2 2017,2018, we capitalized $145$111 million (including $27$20 million of stock-based compensation) and $111$75 million (including $20$17 million of stock-based compensation) of costs associated with internal-use software and website development. For the six months ended June 30, 20162017 and 2017,2018, we capitalized $280$206 million (including $51$41 million of stock-based compensation) and $206$148 million (including $41$30 million of stock-based compensation) of costs associated with internal-use software and website development. Amortization of previously capitalized amounts was $160$145 million and $145$102 million for Q2 20162017 and Q2 2017,2018, and $321$296 million and $296$216 million for the six months ended June 30, 20162017 and 2017.

2018.
General and Administrative
The increase in general and administrative costs in absolute dollars in Q2 20172018 and for the six months ended June 30, 2017,2018, compared to the comparable prior year periods, is primarily due to increases in payroll and related expenses and professional service fees.expenses.

Other Operating Expense, Net
Other operating expense, net was $5566 million and $66$80 million for Q2 20162017 and Q2 2017,2018, and $100$109 million and $109$143 million for the six months ended June 30, 20162017 and 2017,2018, and was primarily related to the amortization of intangible assets.
Interest Income and Expense
Our interest income was $24$44 million and $44$94 million during Q2 20162017 and Q2 2017,2018, and $45$83 million and $83$173 million for the six months ended June 30, 20162017 and 2017.2018. We generally invest our excess cash in investment grade short- to intermediate-term fixed income securities and AAA-rated money market funds. Our interest income corresponds with the average balance of invested funds based on the prevailing rates, which vary depending on the geographies and currencies in which they are invested.
Interest expense was $116$143 million and $143$343 million during Q2 20162017 and Q2 2017,2018, and $233$282 million and $282$673 million for the six months ended June 30, 20162017 and 2017.2018. The increase is primarily due to increases in our capital and finance lease arrangements and long-term debt.
Other Income (Expense), Net
Other income (expense), net was $(14)$137 million and $137$(129) million during Q2 20162017 and Q2 2017,2018, and $66$185 million and $185$109 million for the six months ended June 30, 20162017 and 2017.2018. The primary component of other income (expense), net is related to foreign currency and equity warrant valuation and other investment gains (losses).valuation.
Income Taxes
Our tax provision or benefit from income taxes for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter we update our estimate of the annual effective tax rate, and if our estimated tax rate changes, we make a cumulative adjustment.
Our quarterly tax provision, and our quarterly estimate of our annual effective tax rate, is subject to significant variation due to several factors, including variability in accurately predicting our pre-tax and taxable income and loss and the mix of jurisdictions to which they relate, intercompany transactions, the applicability of special tax regimes, changes in how we do business, acquisitions (including integrations) and investments, audit-related developments, changes in our stock price, changes in our deferred tax assets and liabilities and their valuation, foreign currency gains (losses), tax law developments (including changes in statutes, regulations, case law, and administrative practices),practices, principles, and interpretations related to tax, accounting, and other areas, including European Union state aid rules, and relative changes of expenses or losses for which tax benefits are not recognized. Additionally, our effective tax rate can be more or less volatile based on the amount of pre-tax income or loss. For example, the impact of discrete items and non-deductible expenses on our effective tax rate is greater when our pre-tax income is lower.
The 2017 Tax Act was signed into law on December 22, 2017. The 2017 Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering the statutory corporate tax rate from 35% to 21%, eliminating certain deductions, imposing a mandatory one-time tax on accumulated earnings of foreign subsidiaries, introducing new tax regimes, and changing how foreign earnings are subject to U.S. tax. The 2017 Tax Act also enhanced and extended through 2026 the option to claim accelerated depreciation deductions on qualified property. We have not completed our determination of the accounting implications of the 2017 Tax Act on our tax accruals. However, we have reasonably estimated the effects of the 2017 Tax Act and recorded provisional amounts in our financial statements as of December 31, 2017. We recorded a provisional tax benefit for the impact of the 2017 Tax Act of approximately $789 million. This amount was primarily comprised of the remeasurement of federal net deferred tax liabilities resulting from the permanent reduction in the U.S. statutory corporate tax rate to 21% from 35%, after taking into account the mandatory one-time tax on the accumulated earnings of our foreign subsidiaries. The amount of this one-time tax is not material. As we complete our analysis of the 2017 Tax Act, collect and prepare necessary data, and interpret any additional guidance issued by the U.S. Treasury Department, the IRS, and other standard-setting bodies, we may make adjustments to the provisional amounts. Those adjustments may materially impact our provision for income taxes in the period in which the adjustments are made.
For 2017,2018, we estimate that our effective tax rate will be favorably affected by the impact of excess tax benefits from stock-based compensation and the U.S. federal research and development credit and adversely affected by the recordinglosses incurred in certain foreign jurisdictions for which we may not realize a tax benefit. Losses for which we may not realize a related tax benefit, primarily due to losses of foreign subsidiaries, reduce our pre-tax income without a corresponding reduction in our tax expense, and therefore increase our effective tax rate. We record valuation allowances against the deferred tax assets associated with losses for which we may not realize a related to net operating losses generated in Luxembourg and state income taxes.tax benefit.
Our income tax provision for the six months ended June 30, 2016 was $782 million, which included $70 million of discrete tax benefits primarily attributable to audit-related and tax law developments. Our income tax provision for the six months ended June 30, 2017 was $695 million, which included $197 million of net discrete tax benefits primarily attributable to excess tax benefits from stock-based compensation, partially offset by a valuation allowance we recorded against the deferred tax assets related to net operating losses generated in Luxembourg and the estimated

impact of audit-related developments.
We regularly assess whether it is more likely than not that we will realize our deferred Our income tax assets in each taxing jurisdiction in which we operate. In performing this assessment with respect to each jurisdiction, we review all available evidence, including recent cumulative loss experience and expectations of future earnings, capital gains, and investment in such jurisdiction, the carry-forward periods available to us for tax reporting purposes, and other relevant factors. In Q2 2017, we recognized an estimated charge to tax expense of $600 million to record a valuation allowance against the net deferred tax assets in Luxembourg.
Equity-Method Investment Activity, Net of Tax
Equity-method investment activity, net of tax, was $(15) million and $(2) million during Q2 2016 and Q2 2017, and $(82) million and $(2) millionprovision for the six months ended June 30, 2016 and 2017. The primary components2018 was $361 million, which included $964 million of this activity were impairments recorded in Q1 2016 and our equity-method investment losses during the periods.

net discrete tax benefits primarily attributable to excess tax benefits from stock-based compensation.
Non-GAAP Financial Measures
Regulation G, Conditions for Use of Non-GAAP Financial Measures, and other SEC regulations define and prescribe the conditions for use of certain non-GAAP financial information. Our measures of free cash flows and the effect of foreign exchange rates on our consolidated statements of operations meet the definition of non-GAAP financial measures.
We provide multiple measures of free cash flows because we believe these measures provide additional perspective on the impact of acquiring property and equipment with cash and through capital and finance leases. As a result of the adoption of new accounting guidance, we retrospectively adjusted our consolidated statements of cash flows to reclassify excess tax benefitsadd restricted cash to cash and cash equivalents. See Item 1 of $323 million for the twelve months ended June 30, 2016 from financing activities to operating activities.Part I, “Financial Statements — Note 1 — Accounting Policies.”
Free Cash Flow
Free cash flow is cash flow from operations reduced by “Purchases of property and equipment, including internal-use software and website development, net of proceeds from property and equipment incentives,” which isboth are included in cash flow from investing activities. The following is a reconciliation of free cash flow to the most comparable GAAP cash flow measure, “Net cash provided by (used in) operating activities,” for the trailing twelve months ended June 30, 20162017 and 20172018 (in millions):

Free Cash Flow Less Finance Lease Principal Repayments and Assets Acquired Under Capital Leases
Free cash flow less finance lease principal repayments and assets acquired under capital leases is free cash flow reduced by “Principal repayments of finance lease obligations,” which is included in cash flow from financing activities, and property and equipment acquired under capital leases. In this measure, property and equipment acquired under capital leases is reflected as if these assets had been purchased with cash, which is not the case as these assets have been leased. The following is a reconciliation of free cash flow less finance lease principal repayments and assets acquired under capital leases to the most comparable GAAP cash flow measure, “Net cash provided by (used in) operating activities,” for the trailing twelve months ended June 30, 20162017 and 20172018 (in millions):

All of these free cash flows measures have limitations as they omit certain components of the overall cash flow statement and do not represent the residual cash flow available for discretionary expenditures. For example, these measures of free cash flows do not incorporate the portion of payments representing principal reductions of debt or cash payments for business acquisitions. Additionally, our mix of property and equipment acquisitions with cash or other financing options may change over time. Therefore, we believe it is important to view free cash flows measures only as a complement to our entire consolidated statements of cash flows.
Effect of Foreign Exchange Rates
Information regarding the effect of foreign exchange rates, versus the U.S. Dollar, on our net sales, operating expenses, and operating income is provided to show reported period operating results had the foreign exchange rates remained the same as those in effect in the comparable prior year periods. The effect on our net sales, operating expenses, and operating income from changes in our foreign exchange rates versus the U.S. Dollar is as follows (in millions):

Guidance
We provided guidance on July 27, 2017,26, 2018, in our earnings release furnished on Form 8-K as set forth below. This guidance excludes the impact of our proposed acquisition of Whole Foods Market, Inc. These forward-looking statements reflect Amazon.com’s expectations as of July 27, 2017,26, 2018, and are subject to substantial uncertainty. Our results are inherently unpredictable and may be materially affected by many factors, such as fluctuations in foreign exchange rates, changes in global economic conditions and customer spending, world events, the rate of growth of the Internet, online commerce, and cloud services, as well as those outlined in Item 1A of Part II, “Risk Factors.”
Third Quarter 20172018 Guidance
Net sales are expected to be between $39.25$54.0 billion and $41.75$57.5 billion, or to grow between 20%23% and 28%31% compared with third quarter 2016.2017. This guidance anticipates an unfavorable impact of approximately $125 million or 4030 basis points from foreign exchange rates.
Operating income (loss) is expected to be between $(400) million$1.4 billion and $300 million,$2.4 billion, compared with $575$347 million in third quarter 2016.2017.
This guidance assumes, among other things, that no additional business acquisitions, investments, restructurings, or legal settlements are concluded.


Item 3.Quantitative and Qualitative Disclosures About Market Risk
We are exposed to market risk for the effect of interest rate changes, foreign currency fluctuations, and changes in the market values of our investments. Information relating to quantitative and qualitative disclosures about market risk is set forth below and in Item 2 of Part I, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources.”
Interest Rate Risk
Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio and our long-term debt. Our long-term debt is carried at amortized cost and fluctuations in interest rates do not impact our consolidated financial statements. However, the fair value of our debt, which pays interest at a fixed rate, will generally fluctuate with movements of interest rates, increasing in periods of declining rates of interest and declining in periods of increasing rates of interest. All of our cash equivalent and marketable fixed income securities are designated as available-for-sale and, accordingly, are presented at fair value on our consolidated balance sheets. We generally invest our excess cash in investment grade short- to intermediate-term fixed income securities and AAA-rated money market funds. Fixed income securities may have their fair market value adversely affected due to a rise in interest rates, and we may suffer losses in principal if forced to sell securities that have declined in market value due to changes in interest rates.
Foreign Exchange Risk
During Q2 2017,2018, net sales from our International segment accounted for 30%28% of our consolidated revenues. Net sales and related expenses generated from our internationally-focused websites, and from www.amazon.ca and www.amazon.com.mx (which are included in our North America segment), are primarily denominated in the functional currencies of the corresponding websites and primarily include Euros, Japanese Yen, and British Pounds. The results of operations of, and certain of our intercompany balances associated with, our internationally-focused websites and AWS are exposed to foreign exchange rate fluctuations. Upon consolidation, as foreign exchange rates vary, net sales and other operating results may differ materially from expectations, and we may record significant gains or losses on the remeasurement of intercompany balances. For example, as a result of fluctuations in foreign exchange rates throughout the period compared to rates in effect the prior year, International segment net sales in Q2 2017 decreased2018 increased by $480$727 million in comparison with Q2 2016.2017.
We have foreign exchange risk related to foreign-denominated cash, cash equivalents, and marketable securities (“foreign funds”). Based on the balance of foreign funds as of June 30, 2017,2018, of $7.3$7.9 billion, an assumed 5%, 10%, and 20% adverse change to foreign exchange would result in fair value declines of $365$395 million, $730$795 million, and $1.5$1.6 billion. All investmentscash equivalents and marketable fixed-income securities are classified as “available-for-sale.” Fluctuations in fair value are recorded in “Accumulated other comprehensive loss,” a separate component of stockholders’ equity. Equity securities with readily determinable fair values are included in “Marketable securities” on our consolidated balance sheets and are measured at fair value with changes recognized in net income.
We have foreign exchange risk related to our intercompany balances denominated in various foreign currencies. Based on the intercompany balances as of June 30, 2017,2018, an assumed 5%, 10%, and 20% adverse change to foreign exchange would result in losses of $220$240 million, $460$520 million, and $1.0$1.2 billion, recorded to “Other income (expense), net.”
See Item 2 of Part I, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations — Effect of Foreign Exchange Rates” for additional information on the effect on reported results of changes in foreign exchange rates.
Investment Risk
As of June 30, 2017,2018, our recorded value in equity and equity warrant investments in public and private companies was $623 million. We record our$1.0 billion. Our equity and equity warrant investments in publicly traded companies represent $593 million of our investments as of June 30, 2018, and are recorded at fair value, which is subject to market price volatility, and represents $338 million of our investments as of June 30, 2017.volatility. We evaluateperform a qualitative assessment for our equity and equity warrant investments in private companies forto identify impairment. If this assessment indicates that an impairment when events and circumstances indicate thatexists, we estimate the decline in fair value of such assets below the investment and, if the fair value is less than carrying value, is other-than-temporary.we write down the investment to fair value. Our analysisassessment includes a review of recent operating results and trends, recent sales/acquisitions of the investee securities, and other publicly available data. The current global economic climate provides additional uncertainty. Valuations of private companies are inherently more complex due to the lack of readily available market data. As such, we believe that market sensitivities are not practicable.

Item 4.Controls and Procedures
We carried out an evaluation required by the Securities Exchange Act of 1934 (the “1934 Act”), under the supervision and with the participation of our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rule 13a-15(e) of the 1934 Act, as of the end of the period covered by this report. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the 1934 Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and to provide reasonable assurance that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.
During the most recent fiscal quarter, there has not occurred any change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives as specified above. Management does not expect, however, that our disclosure controls and procedures will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.


PART II. OTHER INFORMATION
 
Item 1.Legal Proceedings
See Item 1 of Part I, “Financial Statements — Note 3 — Commitments and Contingencies — Legal Proceedings.”

Item 1A.Risk Factors
Please carefully consider the following risk factors. If any of the following risks occur, our business, financial condition, operating results, and cash flows could be materially adversely affected. In addition, the current global economic climate amplifies many of these risks.
We Face Intense Competition
Our businesses are rapidly evolving and intensely competitive, and we have many competitors in different industries, including physical, e-commerce, and omnichannel retail, e-commerce services, digital content and electronic devices, and web and infrastructure computing services.services, and across geographies, including cross-border competition. Some of our current and potential competitors have greater resources, longer histories, more customers, and/or greater brand recognition, particularly with our newly-launched products and services and in our newer geographic regions. They may secure better terms from vendors, adopt more aggressive pricing, and devote more resources to technology, infrastructure, fulfillment, and marketing.
Competition may intensify, including with the development of new business models and the entry of new and well-funded competitors, and as our competitors enter into business combinations or alliances and established companies in other market segments expand to become competitive with our business. In addition, new and enhanced technologies, including search, web and infrastructure computing services, digital content, and electronic devices, may increase our competition. The Internet facilitates competitive entry and comparison shopping, and increased competition may reduce our sales and profits.
Our Expansion Places a Significant Strain on our Management, Operational, Financial, and Other Resources
We are rapidly and significantly expanding our global operations, including increasing our product and service offerings and scaling our infrastructure to support our retail and services businesses. This expansion increases the complexity of our business and places significant strain on our management, personnel, operations, systems, technical performance, financial resources, and internal financial control and reporting functions. We may not be able to manage growth effectively, which could damage our reputation, limit our growth, and negatively affect our operating results.
Our Expansion into New Products, Services, Technologies, and Geographic Regions Subjects Us to Additional Business, Legal, Financial, and Competitive Risks
We may have limited or no experience in our newer market segments, and our customers may not adopt our new offerings. These offerings may present new and difficult technology challenges, and we may be subject to claims if customers of these offerings experience service disruptions or failures or other quality issues. In addition, profitability, if any, in our newer activities may be lower than in our older activities, and we may not be successful enough in these newer activities to recoup our investments in them. If any of this were to occur, it could damage our reputation, limit our growth, and negatively affect our operating results.
We May Experience Significant Fluctuations in Our Operating Results and Growth Rate
We may not be able to accurately forecast our growth rate. We base our expense levels and investment plans on sales estimates. A significant portion of our expenses and investments is fixed, and we may not be able to adjust our spending quickly enough if our sales are less than expected.
Our revenue growth may not be sustainable, and our percentage growth rates may decrease. Our revenue and operating profit growth depends on the continued growth of demand for the products and services offered by us or our sellers, and our business is affected by general economic and business conditions worldwide. A softening of demand, whether caused by changes in customer preferences or a weakening of the U.S. or global economies, may result in decreased revenue or growth.
Our sales and operating results will also fluctuate for many other reasons, including due to risks described elsewhere in this section and the following:

our ability to retain and increase sales to existing customers, attract new customers, and satisfy our customers’ demands;
our ability to retain and expand our network of sellers;
our ability to offer products on favorable terms, manage inventory, and fulfill orders;
the introduction of competitive stores, websites, products, services, price decreases, or improvements;
changes in usage or adoption rates of the Internet, e-commerce, electronic devices, and web services, including outside the U.S.;
timing, effectiveness, and costs of expansion and upgrades of our systems and infrastructure;
the success of our geographic, service, and product line expansions;
the extent to which we finance, and the terms of any such financing for, our current operations and future growth;
the outcomes of legal proceedings and claims, which may include significant monetary damages or injunctive relief and could have a material adverse impact on our operating results;
variations in the mix of products and services we sell;
variations in our level of merchandise and vendor returns;
the extent to which we offer free shipping, continue to reduce prices worldwide, and provide additional benefits to our customers;
the extent to which we invest in technology and content, fulfillment, and other expense categories;
increases in the prices of fuel and gasoline, as well as increases in the prices of other energy products and commodities like paper and packing supplies;
the extent to which our equity-method investees record significant operating and non-operating items;
the extent to which operators of the networks between our customers and our websites successfully charge fees to grant our customers unimpaired and unconstrained access to our online services;
our ability to collect amounts owed to us when they become due;
the extent to which use of our services is affected by spyware, viruses, phishing and other spam emails, denial of service attacks, data theft, computer intrusions, outages, and similar events; and
terrorist attacks and armed hostilities.
Our International Operations Expose Us to a Number of Risks
Our international activities are significant to our revenues and profits, and we plan to further expand internationally. In certain international market segments, we have relatively little operating experience and may not benefit from any first-to-market advantages or otherwise succeed. It is costly to establish, develop, and maintain international operations and websites, and promote our brand internationally. Our international operations may not be profitable on a sustained basis.
In addition to risks described elsewhere in this section, our international sales and operations are subject to a number of risks, including:
local economic and political conditions;
government regulation of e-commerce and other services, physical, e-commerce, and omnichannel retail, electronic devices, and competition, and restrictive governmental actions (such as trade protection measures, including export duties and quotas and custom duties and tariffs), nationalization, and restrictions on foreign ownership;
restrictions on sales or distribution of certain products or services and uncertainty regarding liability for products, services, and content, including uncertainty as a result of less Internet-friendly legal systems, local laws, lack of legal precedent, and varying rules, regulations, and practices regarding the physical and digital distribution of media products and enforcement of intellectual property rights;
business licensing or certification requirements, such as for imports, exports, web services, and electronic devices;
limitations on the repatriation and investment of funds and foreign currency exchange restrictions;
limited fulfillment and technology infrastructure;
shorter payable and longer receivable cycles and the resultant negative impact on cash flow;

laws and regulations regarding consumer and data protection, privacy, network security, encryption, payments, and restrictions on pricing or discounts;
lower levels of use of the Internet;
lower levels of consumer spending and fewer opportunities for growth compared to the U.S.;
lower levels of credit card usage and increased payment risk;
difficulty in staffing, developing, and managing foreign operations as a result of distance, language, and cultural differences;
different employee/employer relationships and the existence of works councils and labor unions;
compliance with the U.S. Foreign Corrupt Practices Act and other applicable U.S. and foreign laws prohibiting corrupt payments to government officials and other third parties;
laws and policies of the U.S. and other jurisdictions affecting trade, foreign investment, loans, and taxes; and
geopolitical events, including war and terrorism.
As international e-commerce and other online and web services grow, competition will intensify.intensify, including through adoption of evolving business models such as omnichannel retail. Local companies may have a substantial competitive advantage because of their greater understanding of, and focus on, the local customer, as well as their more established local brand names. We may not be able to hire, train, retain, and manage required personnel, which may limit our international growth.
The People’s Republic of China (“PRC”) and India regulate Amazon’s and its affiliates’ businesses and operations in country through regulations and license requirements that may restrict (i) foreign investment in and operation of the Internet, IT infrastructure, data centers, retail, delivery, and other sectors, (ii) Internet content, and (iii) the sale of media and other products and services. For example, in order to meet local ownership and regulatory licensing requirements, www.amazon.cn is operated by PRC companies that are indirectly owned, either wholly or partially, by PRC nationals. In addition, we provide certain technology services in China in conjunction with third parties that hold PRC licenses to provide services. In India, the government restricts the ownership or control of Indian companies by foreign entities involved in online multi-brand retail trading activities. For www.amazon.in, we provide certain marketing tools and logistics services to third-party sellers to enable them to sell online and deliver to customers, and we hold an indirect minority interestinterests in an entityentities that is aare third-party sellersellers on the www.amazon.in marketplace. Although we believe these structures and activities comply with existing laws, they involve unique risks, and the PRC is actively considering changes in its foreign investment rules that could impact these structures and activities. There are substantial uncertainties regarding the interpretation of PRC and Indian laws and regulations, and it is possible that these governments will ultimately take a view contrary to ours. In addition, our Chinese and Indian businesses and operations may be unable to continue to operate if we or our affiliates are unable to access sufficient funding or in China enforce contractual relationships with respect to management and control of such businesses. If our international activities were found to be in violation of any existing or future PRC, Indian or other laws or regulations or if interpretations of those laws and regulations were to change, our businesses in those countries could be subject to fines and other financial penalties, have licenses revoked, or be forced to shut down entirely.
If We Do Not Successfully Optimize and Operate Our Fulfillment Network and Data Centers, Our Business Could Be Harmed
If we do not adequately predict customer demand or otherwise optimize and operate our fulfillment network and data centers successfully, it could result in excess or insufficient fulfillment or data center capacity, or result in increased costs, impairment charges, or both, or harm our business in other ways. As we continue to add fulfillment and data center capability or add new businesses with different requirements, our fulfillment and data center networks become increasingly complex and operating them becomes more challenging. There can be no assurance that we will be able to operate our networks effectively.
In addition, a failure to optimize inventory in our fulfillment network will increase our net shipping cost by requiring long-zone or partial shipments. We and our co-sourcers may be unable to adequately staff our fulfillment network and customer service centers. If the other businesses on whose behalf we perform inventory fulfillment services deliver product to our fulfillment centers in excess of forecasts, we may be unable to secure sufficient storage space and may be unable to optimize our fulfillment network.
We rely on a limited number of shipping companies to deliver inventory to us and completed orders to our customers. If we are not able to negotiate acceptable terms with these companies or they experience performance problems or other difficulties, it could negatively impact our operating results and customer experience. In addition, our ability to receive inbound inventory efficiently and ship completed orders to customers also may be negatively affected by inclement weather, fire, flood, power loss, earthquakes, labor disputes, acts of war or terrorism, acts of God, and similar factors.

Under some of our commercial agreements, we maintain the inventory of other companies, thereby increasing the complexity of tracking inventory and operating our fulfillment network. Our failure to properly handle such inventory or the inability of these other companies to accurately forecast product demand would result in unexpected costs and other harm to our business and reputation.
The Seasonality of Our Business Places Increased Strain on Our Operations
We expect a disproportionate amount of our net sales to occur during our fourth quarter. If we do not stock or restock popular products in sufficient amounts such that we fail to meet customer demand, it could significantly affect our revenue and our future growth. If we overstock products, we may be required to take significant inventory markdowns or write-offs and incur commitment costs, which could reduce profitability. We may experience an increase in our net shipping cost due to complimentary upgrades, split-shipments, and additional long-zone shipments necessary to ensure timely delivery for the holiday season. If too many customers access our websites within a short period of time due to increased holiday demand, we may experience system interruptions that make our websites unavailable or prevent us from efficiently fulfilling orders, which may reduce the volume of goods we sell and the attractiveness of our products and services. In addition, we may be unable to adequately staff our fulfillment network and customer service centers during these peak periods and delivery and other fulfillment companies and customer service co-sourcers may be unable to meet the seasonal demand. We also face risks described elsewhere in this Item 1A relating to fulfillment network optimization and inventory.
We generally have payment terms with our retail vendors that extend beyond the amount of time necessary to collect proceeds from our consumer customers. As a result of holiday sales, as of December 31 of each year, our cash, cash equivalents, and marketable securities balances typically reach their highest level (other than as a result of cash flows provided by or used in investing and financing activities). This operating cycle results in a corresponding increase in accounts payable as of December 31. Our accounts payable balance generally declines during the first three months of the year, resulting in a corresponding decline in our cash, cash equivalents, and marketable securities balances.
Our Business Could Suffer if We Are Unsuccessful in Making, Integrating, and Maintaining Commercial Agreements, Strategic Alliances, and Other Business Relationships
We provide e-commerce and other services to businesses through commercial agreements, strategic alliances, and business relationships. Under these agreements, we provide web services, technology, fulfillment, computing, digital storage, and other services, as well as enable sellers to offer products or services through our websites. These arrangements are complex and require substantial infrastructure capacity, personnel, and other resource commitments, which may limit the amount of business we can service. We may not be able to implement, maintain, and develop the components of these commercial relationships, which may include web services, fulfillment, customer service, inventory management, tax collection, payment processing, hardware, content, and third-party software, and engaging third parties to perform services. The amount of compensation we receive under certain of our commercial agreements is partially dependent on the volume of the other company’s sales. Therefore, if the other company’s offering is not successful, the compensation we receive may be lower than expected or the agreement may be terminated. Moreover, we may not be able to enter into additional commercial relationships and strategic alliances on favorable terms. We also may be subject to claims from businesses to which we provide these services if we are unsuccessful in implementing, maintaining, or developing these services.
As our agreements terminate, we may be unable to renew or replace these agreements on comparable terms, or at all. We may in the future enter into amendments on less favorable terms or encounter parties that have difficulty meeting their contractual obligations to us, which could adversely affect our operating results.
Our present and future e-commerce services agreements, other commercial agreements, and strategic alliances create additional risks such as:
disruption of our ongoing business, including loss of management focus on existing businesses;
impairment of other relationships;
variability in revenue and income from entering into, amending, or terminating such agreements or relationships; and
difficulty integrating under the commercial agreements.
Our Business Could Suffer if We Are Unsuccessful in Making, Integrating, and Maintaining Acquisitions and Investments
We have acquired and invested in a number of companies, and we may acquire or invest in or enter into joint ventures with additional companies. These transactions (such as our proposed acquisition of Whole Foods Market, Inc.) create risks such as:
disruption of our ongoing business, including loss of management focus on existing businesses;

problems retaining key personnel;
additional operating losses and expenses of the businesses we acquired or in which we invested;
the potential impairment of tangible and intangible assets and goodwill, including as a result of acquisitions;
the potential impairment of customer and other relationships of the company we acquired or in which we invested or our own customers as a result of any integration of operations;
the difficulty of completing such transactions and achieving anticipated benefits within expected timeframes, or at all;
the difficulty of incorporating acquired operations, technology, and rights into our offerings, and unanticipated expenses related to such integration;
the difficulty of integrating a new company’s accounting, financial reporting, management, information and information security, human resource, and other administrative systems to permit effective management, and the lack of control if such integration is delayed or not implemented;
for investments in which an investee’s financial performance is incorporated into our financial results, either in full or in part, the dependence on the investee’s accounting, financial reporting, and similar systems, controls, and processes;
the difficulty of implementing at companies we acquire the controls, procedures, and policies appropriate for a larger public company;
the risks associated with businesses we acquire or invest in, which may differ from or be more significant than the risks our other businesses face;
potential unknown liabilities associated with a company we acquire or in which we invest; and
for foreign transactions, additional risks related to the integration of operations across different cultures and languages, and the economic, political, and regulatory risks associated with specific countries.
As a result of future acquisitions or mergers, we might need to issue additional equity securities, spend our cash, or (such as for our proposed acquisition of Whole Foods Market, Inc.) incur debt, contingent liabilities, or amortization expenses related to intangible assets, any of which could reduce our profitability and harm our business or only be available on unfavorable terms, if at all. In addition, valuations supporting our acquisitions and strategic investments could change rapidly given the current global economic climate. We could determine that such valuations have experienced impairments or other-than-temporary declines in fair value which could adversely impact our financial results.
We Have Foreign Exchange Risk
The results of operations of, and certain of our intercompany balances associated with, our international websites and product and service offerings are exposed to foreign exchange rate fluctuations. Upon translation, operating results may differ materially from expectations, and we may record significant gains or losses on the remeasurement of intercompany balances. As we have expanded our international operations, our exposure to exchange rate fluctuations has increased. We also hold cash equivalents and/or marketable securities in foreign currencies including British Pounds, Euros, and Japanese Yen. If the U.S. Dollar strengthens compared to these currencies, cash equivalents, and marketable securities balances, when translated, may be materially less than expected and vice versa.
The Loss of Key Senior Management Personnel Could Negatively Affect Our Business
We depend on our senior management and other key personnel, particularly Jeffrey P. Bezos, our President, CEO, and Chairman. We do not have “key person” life insurance policies. The loss of any of our executive officers or other key employees could harm our business.

We Could Be Harmed by Data Loss or Other Security Breaches
As a result of our services being web-based and the fact that we process, store, and transmit large amounts of data, including personal information, for our customers, failure to prevent or mitigate data loss or other security breaches, including breaches of our vendors’ technology and systems, could expose us or our customers to a risk of loss or misuse of such information, adversely affect our operating results, result in litigation or potential liability for us, and otherwise harm our business. We use third-party technology and systems for a variety of reasons, including, without limitation, encryption and authentication technology, employee email, content delivery to customers, back-office support, and other functions. Some subsidiaries had past security breaches, and, although they did not have a material adverse effect on our operating results, there can be no assurance of a similar result in the future. Although we have developed systems and processes that are designed to protect customer information and prevent data loss and other security breaches, including systems and processes designed to reduce the impact of a security breach at a third-party vendor, such measures cannot provide absolute security.
We Face Risks Related to System Interruption and Lack of Redundancy
We experience occasional system interruptions and delays that make our websites and services unavailable or slow to respond and prevent us from efficiently fulfilling orders or providing services to third parties, which may reduce our net sales and the attractiveness of our products and services. If we are unable to continually add software and hardware, effectively upgrade our systems and network infrastructure, and take other steps to improve the efficiency of our systems, it could cause system interruptions or delays and adversely affect our operating results.
Our computer and communications systems and operations could be damaged or interrupted by fire, flood, power loss, telecommunications failure, earthquakes, acts of war or terrorism, acts of God, computer viruses, physical or electronic break-ins, and similar events or disruptions. Any of these events could cause system interruption, delays, and loss of critical data, and could prevent us from accepting and fulfilling customer orders and providing services, which could make our product and service offerings less attractive and subject us to liability. Our systems are not fully redundant and our disaster recovery planning may not be sufficient. In addition, we may have inadequate insurance coverage to compensate for any related losses. Any of these events could damage our reputation and be expensive to remedy.
We Face Significant Inventory Risk
In addition to risks described elsewhere in this Item 1A relating to fulfillment network and inventory optimization by us and third parties, we are exposed to significant inventory risks that may adversely affect our operating results as a result of seasonality, new product launches, rapid changes in product cycles and pricing, defective merchandise, changes in consumer demand and consumer spending patterns, changes in consumer tastes with respect to our products, spoilage, and other factors. We endeavor to accurately predict these trends and avoid overstocking or understocking products we manufacture and/or sell. Demand for products, however, can change significantly between the time inventory or components are ordered and the date of sale. In addition, when we begin selling or manufacturing a new product, it may be difficult to establish vendor relationships, determine appropriate product or component selection, and accurately forecast demand. The acquisition of certain types of inventory or components may require significant lead-time and prepayment and they may not be returnable. We carry a broad selection and significant inventory levels of certain products, such as consumer electronics, and we may be unable to sell products in sufficient quantities or during the relevant selling seasons. Any one of the inventory risk factors set forth above may adversely affect our operating results.
We May Not Be Able to Adequately Protect Our Intellectual Property Rights or May Be Accused of Infringing Intellectual Property Rights of Third Parties
We regard our trademarks, service marks, copyrights, patents, trade dress, trade secrets, proprietary technology, and similar intellectual property as critical to our success, and we rely on trademark, copyright, and patent law, trade secret protection, and confidentiality and/or license agreements with our employees, customers, and others to protect our proprietary rights. Effective intellectual property protection may not be available in every country in which our products and services are made available. We also may not be able to acquire or maintain appropriate domain names in all countries in which we do business. Furthermore, regulations governing domain names may not protect our trademarks and similar proprietary rights. We may be unable to prevent third parties from acquiring domain names that are similar to, infringe upon, or diminish the value of our trademarks and other proprietary rights.
We may not be able to discover or determine the extent of any unauthorized use of our proprietary rights. Third parties that license our proprietary rights also may take actions that diminish the value of our proprietary rights or reputation. The protection of our intellectual property may require the expenditure of significant financial and managerial resources. Moreover, the steps we take to protect our intellectual property may not adequately protect our rights or prevent third parties from infringing or misappropriating our proprietary rights. We also cannot be certain that others will not independently develop or otherwise acquire equivalent or superior technology or other intellectual property rights.

Other parties also may claim that we infringe their proprietary rights. We have been subject to, and expect to continue to be subject to, claims and legal proceedings regarding alleged infringement by us of the intellectual property rights of third parties. Such claims, whether or not meritorious, may result in the expenditure of significant financial and managerial resources, injunctions against us, or the payment of damages, including to satisfy indemnification obligations. We may need to obtain licenses from third parties who allege that we have infringed their rights, but such licenses may not be available on terms acceptable to us or at all. In addition, we may not be able to obtain or utilize on terms that are favorable to us, or at all, licenses or other rights with respect to intellectual property we do not own. These risks have been amplified by the increase in third parties whose sole or primary business is to assert such claims.
Our digital content offerings depend in part on effective digital rights management technology to control access to digital content. If the digital rights management technology that we use is compromised or otherwise malfunctions, we could be subject to claims, and content providers may be unwilling to include their content in our service.
We Have a Rapidly Evolving Business Model and Our Stock Price Is Highly Volatile
We have a rapidly evolving business model. The trading price of our common stock fluctuates significantly in response to, among other risks, the risks described elsewhere in this Item 1A, as well as:
changes in interest rates;
conditions or trends in the Internet and the industry segments we operate in;
quarterly variations in operating results;
fluctuations in the stock market in general and market prices for Internet-related companies in particular;
changes in financial estimates by us or securities analysts and recommendations by securities analysts;
changes in our capital structure, including issuance of additional debt or equity to the public;
changes in the valuation methodology of, or performance by, other e-commerce or technology companies; and
transactions in our common stock by major investors and certain analyst reports, news, and speculation.
Volatility in our stock price could adversely affect our business and financing opportunities and force us to increase our cash compensation to employees or grant larger stock awards than we have historically, which could hurt our operating results or reduce the percentage ownership of our existing stockholders, or both.
Government Regulation Is Evolving and Unfavorable Changes Could Harm Our Business
We are subject to general business regulations and laws, as well as regulations and laws specifically governing the Internet, e-commerce, electronic devices, and other services. Existing and future laws and regulations may impede our growth. These regulations and laws may cover taxation, privacy, data protection, pricing, content, copyrights, distribution, transportation, mobile communications, electronic device certification, electronic waste, energy consumption, environmental regulation, electronic contracts and other communications, competition, consumer protection, employment, trade and protectionist measures, web services, the provision of online payment services, information reporting requirements, unencumbered Internet access to our services or access to our facilities, the design and operation of websites, health and sanitation standards, the characteristics and quality of products and services, product labeling, and the commercial operation of unmanned aircraft systems. It is not clear how existing laws governing issues such as property ownership, libel, and personal privacy apply to the Internet, e-commerce, digital content, and web services. Jurisdictions may regulate consumer-to-consumer online businesses, including certain aspects of our seller programs. Unfavorable regulations and laws could diminish the demand for, or availability of, our products and services and increase our cost of doing business.
We Could Be Subject to Additional Sales Tax or Other Indirect Tax Liabilities
An increasing number of states and foreign jurisdictions have considered or adopted laws or administrative practices, with or without notice, that impose new taxes on all or a portion of gross revenue or other similar amounts or impose additional obligations on remote sellers and online marketplaces to collect transaction taxes such as sales, consumption, value added, or similar taxes. Additionally, a June 2018 U.S. Supreme Court decision held that states can require remote sellers to collect state and local sales taxes, which, given the scope of our operations, could increase the complexity and risks for us to comply with such laws. We may not have sufficient lead time to build systems and processes to collect these taxes.taxes properly, or at all. Failure to comply with such laws or administrative practices, or a successful assertion by such states or foreign jurisdictions requiring us to collect taxes where we do not, could result in substantial tax liabilities, including for past sales, as well as penalties and interest. In addition, if the tax authorities in jurisdictions where we are already subject to sales tax or other indirect tax obligations were successfully to challenge our positions, our tax liability could increase substantially. In the U.S., Supreme Court decisions restrict states’ rights to require remote sellers to collect state and local sales taxes (although some states are seeking to have the Supreme Court revisit these decisions). We support a federal law that would allow states to require sales tax collection by remote sellers under a nationwide system.

We are also subject to U.S. (federal and state) and foreign laws, regulations, and administrative practices that require us to collect information from our customers, vendors, merchants, and other third parties for tax reporting purposes and report such information to various government agencies. The scope of such requirements continues to expand, requiring us to develop and implement new compliance systems. Failure to comply with such laws and regulations could result in significant penalties.
We Could Be Subject to Additional Income Tax Liabilities
We are subject to income taxes in the U.S. (federal and state) and numerous foreign jurisdictions. Tax laws, regulations, and administrative practices in various jurisdictions may be subject to significant change, with or without notice, due to economic, political, and other conditions, and significant judgment is required in evaluating and estimating our provision and accruals for these taxes. There are many transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. Our effective tax rates could be affected by numerous factors, such as intercompany transactions, the relative amount of our foreign earnings, including earnings being lower than anticipated in jurisdictions where we have lower statutory rates and higher than anticipated in jurisdictions where we have higher statutory rates, the applicability of special tax regimes, losses incurred in jurisdictions for which we are not able to realize the related tax benefit, changes in foreign currency exchange rates, entry into new businesses and geographies, and changes to our existing businesses and operations, acquisitions (including integrations) and investments and how they are financed, changes in our stock price, changes in our deferred tax assets and liabilities and their valuation, and changes in the relevant tax, accounting, and other laws, regulations, administrative practices, principles, and interpretations related to tax, accounting, and other areas, including fundamentalEuropean Union state aid rules. In addition, a number of countries are actively pursuing changes to thetheir tax laws applicable to corporate multinationals.multinationals, such as the recently enacted U.S. tax reform legislation commonly referred to as the U.S. Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”). Finally, foreign governments may enact tax laws in response to the 2017 Tax Act that could result in further changes to global taxation and materially affect our financial position and results of operations.
The 2017 Tax Act significantly changes how the U.S. taxes corporations. The 2017 Tax Act requires complex computations to be performed that were not previously required in U.S. tax law, significant judgments to be made in interpretation of the provisions of the 2017 Tax Act and significant estimates in calculations, and the preparation and analysis of information not previously relevant or regularly produced. The U.S., Treasury Department, the European UnionIRS, and its member states, and a number of other countries are actively pursuing changes in this regard.
Except as required under U.S. tax laws, we do not provide for U.S. taxesstandard-setting bodies could interpret or issue guidance on our undistributed earnings of foreign subsidiaries that have not been previously taxed since we intend to invest such undistributed earnings indefinitely outsidehow provisions of the U.S. If2017 Tax Act will be applied or otherwise administered that is different from our intent changes or if these fundsinterpretation. As we complete our analysis of the 2017 Tax Act, collect and prepare necessary data, and interpret any additional guidance, we may make adjustments to provisional amounts that we have recorded that may materially impact our provision for income taxes in the period in which the adjustments are needed for our U.S. operations, we would be required to accrue or pay U.S. taxes on some or all of these undistributed earnings and our effective tax rate would be adversely affected. made.
We are also currently subject to audit in various jurisdictions, and these jurisdictions may assess additional income tax liabilities against us. Developments in an audit, litigation, or the relevant laws, regulations, administrative practices, principles, and interpretations could have a material effect on our operating results or cash flows in the period or periods for which that development occurs, as well as for prior and subsequent periods. For instance, the IRS is seeking to increase our U.S. taxable income related to transfer pricing with our foreign subsidiaries for transactions undertaken in 2005 and 2006, and we have been contesting the matter in U.S. Tax Court. On March 23, 2017, the U.S. Tax Court issued its decision regarding the issues raised in the IRS NOPAs. The Tax Court rejected the approach from the IRS NOPAs in determining transfer pricing adjustments in 2005 and 2006 for the transactions undertaken with our foreign subsidiaries and adopted, with adjustments, our suggested approach. The decision is subject to appeal. If the Tax Court decision were reversed on appeal or if the IRS were to successfully assert transfer pricing adjustments of a similar nature to the NOPAs for transactions in subsequent years, we could be subject to significant additional tax liabilities. In addition, in October 2014, the European Commission opened a formal investigation to examine whether decisions by the tax authorities in Luxembourg with regard to the corporate income tax paid by certain of our subsidiaries comply with European Union rules on state aid. If this matter is adversely resolved, Luxembourg may be required to assess, and we may be required to pay, additional amounts with respect to current and prior periods and our taxes in the future could increase. Although we believe our tax estimates are reasonable, the final outcome of tax audits, investigations, and any related litigation could be materially different from our historical income tax provisions and accruals.
Our Supplier Relationships Subject Us to a Number of Risks
We have significant suppliers, including licensors, and in some cases, limited or single-sources of supply, that are important to our sourcing, services, manufacturing, and any related ongoing servicing of merchandise and content. We do not have long-term arrangements with most of our suppliers to guarantee availability of merchandise, content, components, or services, particular payment terms, or the extension of credit limits. If our current suppliers were to stop selling or licensing merchandise, content, components, or services to us on acceptable terms, or delay delivery, including as a result of one or more supplier bankruptcies due to poor economic conditions, as a result of natural disasters, or for other reasons, we may be unable to procure alternatives from other suppliers in a timely and efficient manner and on acceptable terms, or at all. In addition, if our suppliers or other vendors violate applicable laws, regulations, our code of standards and responsibilities, or implement practices regarded as unethical, unsafe, or hazardous to the environment, it could damage our reputation, limit our growth, and negatively affect our operating results.

We May Be Subject to Risks Related to Government Contracts and Related Procurement Regulations
Our contracts with U.S., as well as state, local, and foreign, government entities are subject to various procurement regulations and other requirements relating to their formation, administration, and performance. We may be subject to audits and investigations relating to our government contracts, and any violations could result in various civil and criminal penalties and administrative sanctions, including termination of contract, refunding or suspending of payments, forfeiture of profits, payment of fines, and suspension or debarment from future government business. In addition, such contracts may provide for termination by the government at any time, without cause.

We May Be Subject to Product Liability Claims if People or Property Are Harmed by the Products We Sell or Manufacture
Some of the products we sell or manufacture may expose us to product liability or food safety claims relating to personal injury or illness, death, or environmental or property damage, and may require product recalls or other actions. Certain third parties also sell products using our e-commerce services that may increase our exposure to product liability claims, such as if these sellers do not have sufficient protection from such claims. Although we maintain liability insurance, we cannot be certain that our coverage will be adequate for liabilities actually incurred or that insurance will continue to be available to us on economically reasonable terms, or at all. In addition, some of our agreements with our vendors and sellers do not indemnify us from product liability.
We Are Subject to Payments-Related Risks
We accept payments using a variety of methods, including credit card, debit card, credit accounts (including promotional financing), gift cards, direct debit from a customer’s bank account, consumer invoicing, physical bank check, and payment upon delivery. For existing and future payment options we offer to our customers, we may become subject to additional regulations and compliance requirements (including obligations to implement enhanced authentication processes that could result in significant costs and reduce the ease of use of our payments products), as well as fraud. For certain payment methods, including credit and debit cards, we pay interchange and other fees, which may increase over time and raise our operating costs and lower profitability. We rely on third parties to provide certain Amazon-branded payment methods and payment processing services, including the processing of credit cards, debit cards, electronic checks, and promotional financing. In each case, it could disrupt our business if these companies become unwilling or unable to provide these services to us. We also offer co-branded credit card programs, which could adversely affect our operating results if terminated. We are also subject to payment card association operating rules, including data security rules, certification requirements, and rules governing electronic funds transfers, which could change or be reinterpreted to make it difficult or impossible for us to comply. If we fail to comply with these rules or requirements, or if our data security systems are breached or compromised, we may be liable for card issuing banks’ costs, subject to fines and higher transaction fees, and lose our ability to accept credit and debit card payments from our customers, process electronic funds transfers, or facilitate other types of online payments, and our business and operating results could be adversely affected.
In addition, we provide regulated services in certain jurisdictions because we enable customers to keep account balances with us and transfer money to third parties, and because we provide services to third parties to facilitate payments on their behalf. In these jurisdictions, we may be subject to requirements for licensing, regulatory inspection, bonding and capital maintenance, the use, handling, and segregation of transferred funds, consumer disclosures, and authentication. We are also subject to or voluntarily comply with a number of other laws and regulations relating to payments, money laundering, international money transfers, privacy and information security, and electronic fund transfers. If we were found to be in violation of applicable laws or regulations, we could be subject to additional requirements and civil and criminal penalties, or forced to cease providing certain services.
We Could Be Liable for Fraudulent or Unlawful Activities of Sellers
The law relating to the liability of providers of online payment services is currently unsettled. In addition, governmental agencies could require changes in the way this business is conducted. Under our seller programs, we may be unable to prevent sellers from collecting payments, fraudulently or otherwise, when buyers never receive the products they ordered or when the products received are materially different from the sellers’ descriptions. Under our A2Z Guarantee, we reimburse buyers for payments up to certain limits in these situations, and as our marketplacethird-party seller sales grow, the cost of this program will increase and could negatively affect our operating results. We also may be unable to prevent sellers on our sites or through other seller sites from selling unlawful goods, selling goods in an unlawful manner, or violating the proprietary rights of others, and could face civil or criminal liability for unlawful activities by our sellers.

We are unable to accurately to calculate the net profit attributable to these transactions. We do not plan to continue selling to these accounts in the future. Our review is ongoing and we are enhancing our processes designed to identify transactions associated with individuals and entities covered by the ITRA.
