Accounting Policies [Abstract]
Summary of Business and Significant Accounting Policies	Summary of Business and Significant Accounting Policies Description of Business Salesforce.com, inc. (the “Company”) is a leading provider of enterprise software, delivered through the cloud, with a focus on customer relationship management, or CRM. The Company introduced its first CRM solution in 2000, and has since expanded its service offerings into new areas and industries with new editions, features and platform capabilities. The Company's core mission is to empower its customers to connect with their customers in entirely new ways through cloud, mobile, social, blockchain, voice, advanced analytics and artificial intelligence (“AI”) technologies. Salesforce’s Customer 360 is an integrated platform that unites sales, service, marketing, commerce, integration, analytics and more to give companies a single, shared view of their customers. Fiscal Year The Company’s fiscal year ends on January 31. References to fiscal 2021, for example, refer to the fiscal year ending January 31, 2021. Basis of Presentation The accompanying condensed consolidated balance sheet as of October 31, 2020 and the condensed consolidated statements of operations, condensed consolidated statements of comprehensive income (loss), condensed consolidated statements of stockholders' equity and condensed consolidated statements of cash flows for the three and nine months ended October 31, 2020 and 2019 are unaudited. These financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the financial information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of the Company’s management, the unaudited condensed consolidated financial statements include all adjustments necessary for the fair presentation of the Company’s balance sheet as of October 31, 2020, and its results of operations, including its comprehensive income (loss), stockholders' equity and its cash flows for the three and nine months ended October 31, 2020 and 2019. All adjustments are of a normal recurring nature. The results for the three and nine months ended October 31, 2020 are not necessarily indicative of the results to be expected for any subsequent quarter or for the fiscal year ending January 31, 2021. These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2020, filed with the Securities and Exchange Commission (the “SEC”) on March 5, 2020. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions in the Company’s condensed consolidated financial statements and notes thereto. Significant estimates and assumptions made by management include the determination of: • the fair value of assets acquired and liabilities assumed for business combinations; • the standalone selling price (“SSP”) of performance obligations for revenue contracts with multiple performance obligations; • the valuation of privately-held strategic investments, including impairments; • the recognition, measurement and valuation of current and deferred income taxes and uncertain tax positions; • the average period of benefit associated with costs capitalized to obtain revenue contracts; • the useful lives of intangible assets; and • the fair value of certain stock awards issued. Actual results could differ materially from those estimates. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the result of which forms the basis for making judgments about the carrying values of assets and liabilities. In December 2019, the novel coronavirus and resulting disease (“COVID-19”) was reported and in March 2020 the World Health Organization declared it a pandemic. The extent of the impact of the COVID-19 pandemic on the Company’s operational and financial performance depends on certain developments, including the duration of the pandemic, impact on the Company’s customers and its sales and renewal cycles, and impact on the Company’s employees, as discussed in more detail in Part I, Item 2 “Management’s Discussion and Analysis of Financial Condition and Results of Operations”. These estimates may change, as new events occur and additional information is obtained, and such changes will be recognized in the condensed consolidated financial statements as soon as they become known. Actual results could differ from these estimates and any such differences may be material to the Company’s financial statements. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Segments The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”), in deciding how to allocate resources and assess performance. Over the past few years, the Company has completed a number of acquisitions. These acquisitions have allowed the Company to expand its offerings, presence and reach in various market segments of the enterprise cloud computing market. While the Company has offerings in multiple enterprise cloud computing market segments, including as a result of the Company's acquisitions, and operates in multiple countries, the Company’s business operates in one operating segment because most of the Company's offerings operate on its single Customer 360 Platform and most of the Company's products are deployed in a nearly identical way, and the Company’s CODM evaluates the Company’s financial information and resources and assesses the performance of these resources on a consolidated basis. Concentrations of Credit Risk, Significant Customers and Investments The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities and accounts receivable. Collateral is not required for accounts receivable. The Company maintains an allowance for its doubtful accounts receivable due to estimated credit losses. This allowance is based upon historical loss patterns, the number of days that billings are past due, an evaluation of the potential risk of loss associated with delinquent accounts and current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss patterns. The Company records the allowance against bad debt expense through the condensed consolidated statement of operations up to the amount of revenues recognized to date. Any incremental allowance is recorded as an offset to unearned revenue on the condensed consolidated balance sheet. Receivables are written-off and charged against the recorded allowance when the Company has exhausted collection efforts without success. No single customer accounted for more than five percent of accounts receivable at October 31, 2020 and January 31, 2020. No single customer accounted for five percent or more of total revenue during the nine months ended October 31, 2020 and 2019. As of October 31, 2020 and January 31, 2020, assets located outside the Americas were 13 percent and 12 percent of total assets, respectively. As of October 31, 2020 and January 31, 2020, assets located in the United States were 85 percent and 87 percent of total assets, respectively. The Company is also exposed to concentrations of risk in its strategic investment portfolio. As of October 31, 2020, the Company held one publicly traded investment with a carrying value that was individually greater than 35 percent of its total strategic investments, one publicly traded investment with a carrying value that was individually approximately 20 percent of its total strategic investments and one privately held investment individually greater than five percent of its total strategic investments. As of January 31, 2020, the Company held five investments that were individually greater than five percent of its total strategic investments, of which one was publicly traded and four were privately held. The publicly traded investments held as of October 31, 2020 are different than the publicly traded investment that was held as of January 31, 2020. Revenue Recognition The Company derives its revenues from two sources: (1) subscription revenues, which are comprised of subscription fees from customers accessing the Company’s enterprise cloud computing services (collectively, “Cloud Services”), software licenses, and from customers paying for additional support beyond the standard support that is included in the basic subscription fees; and (2) related professional services such as process mapping, project management and implementation services. Other revenue consists primarily of training fees. Revenue is recognized upon transfer of control of promised products and services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. If the consideration promised in a contract includes a variable amount, for example, overage fees, contingent fees or service level penalties, the Company includes an estimate of the amount it expects to receive for the total transaction price if it is probable that a significant reversal of cumulative revenue recognized will not occur. The Company determines the amount of revenue to be recognized through the application of the following steps: • Identification of the contract, or contracts, with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when or as the Company satisfies the performance obligations. The Company’s subscription service arrangements are non-cancelable and do not contain refund-type provisions. Subscription and Support Revenues Subscription and support revenues are comprised of fees that provide customers with access to Cloud Services, software licenses and related support and updates during the term of the arrangement. Cloud Services allow customers to use the Company's multi-tenant software without taking possession of the software. Revenue is generally recognized ratably over the contract term. With the May 2018 acquisition of MuleSoft, Inc. (“MuleSoft”) and the August 2019 acquisition of Tableau Software, Inc. (“Tableau”), subscription and support revenues also includes revenues associated with software licenses. These licenses for on-premises software provide the customer with a right to use the software as it exists when made available. Customers purchase these term licenses through a subscription. Revenues from distinct licenses are generally recognized upfront when the software is made available to the customer. In cases where the Company allocates revenue to software updates and support revenue, the allocated revenue is recognized as the updates are provided, which is generally ratably over the contract term. The Company typically invoices its customers annually. Typical payment terms provide that customers pay within 30 days of invoice. Amounts that have been invoiced are recorded in accounts receivable and in unearned revenue or revenue, depending on whether transfer of control to customers has occurred. Professional Services and Other Revenues The Company’s professional services contracts are either on a time and materials, fixed fee or subscription basis. These revenues are recognized as the services are rendered for time and materials contracts, on a proportional performance basis for fixed price contracts or ratably over the contract term for subscription professional services contracts. Training revenues are recognized as the services are performed. Significant Judgments - Contracts with Multiple Performance Obligations The Company enters into contracts with its customers that may include promises to transfer multiple Cloud Services, software licenses, premium support and professional services. A performance obligation is a promise in a contract with a customer to transfer products or services that are distinct. Determining whether products and services are distinct performance obligations that should be accounted for separately or combined as one unit of accounting may require significant judgment. Cloud Services and software licenses are distinct because such offerings are often sold separately. In determining whether professional services are distinct, the Company considers the following factors for each professional services agreement: availability of the services from other vendors, the nature of the professional services, the timing of when the professional services contract was signed in comparison to the subscription start date and the contractual dependence of the service on the customer’s satisfaction with the professional services work. To date, the Company has concluded that professional services included in contracts with multiple performance obligations are distinct. The Company allocates the transaction price to each performance obligation on a relative SSP basis. The SSP is the price at which the Company would sell a promised product or service separately to a customer. Judgment is required to determine the SSP for each distinct performance obligation. The Company determines SSP by considering its overall pricing objectives and market conditions. Significant pricing practices taken into consideration include the Company’s discounting practices, the size and volume of the Company’s transactions, the customer demographic, the geographic area where services are sold, price lists, the Company's go-to-market strategy, historical sales and contract prices. In instances where the Company does not sell or price a product or service separately, the Company determines relative fair value using information that may include market conditions or other observable inputs. As the Company’s go-to-market strategies evolve, the Company may modify its pricing practices in the future, which could result in changes to SSP. In certain cases, the Company is able to establish SSP based on observable prices of products or services sold or priced separately in comparable circumstances to similar customers. The Company uses a single amount to estimate SSP when it has observable prices. If SSP is not directly observable, for example when pricing is highly variable, the Company uses a range of SSP. The Company determines the SSP range using information that may include pricing practices or other observable inputs. The Company typically has more than one SSP for individual products and services due to the stratification of those products and services by customer size and geography. Costs Capitalized to Obtain Revenue Contracts The Company capitalizes incremental costs of obtaining non-cancelable Cloud Services subscription, ongoing Cloud Services support and license support revenue contracts. For contracts with on-premises software licenses where revenue is recognized upfront when the software is made available to the customer, costs allocable to those licenses are expensed as they are incurred. Capitalized amounts consist primarily of sales commissions paid to the Company’s direct sales force. Capitalized amounts also include (1) amounts paid to employees other than the direct sales force who earn incentive payouts under annual compensation plans that are tied to the value of contracts acquired, (2) commissions paid to employees upon renewals of subscription and support contracts, (3) the associated payroll taxes and fringe benefit costs associated with the payments to the Company’s employees, and (4) to a lesser extent, success fees paid to partners in emerging markets where the Company has a limited presence. Costs capitalized related to new revenue contracts are amortized on a straight-line basis over four years, which, although longer than the typical initial contract period, reflects the average period of benefit, including expected contract renewals. In arriving at this average period of benefit, the Company evaluated both qualitative and quantitative factors which included the estimated life cycles of its offerings and its customer attrition. Additionally, the Company amortizes capitalized costs for renewals and success fees paid to partners over two years. The capitalized amounts are recoverable through future revenue streams under all non-cancelable customer contracts. The Company periodically evaluates whether there have been any changes in its business, the market conditions in which it operates or other events which would indicate that its amortization period should be changed or if there are potential indicators of impairment. Amortization of capitalized costs to obtain revenue contracts is included in marketing and sales expense in the accompanying condensed consolidated statements of operations. During the nine months ended October 31, 2020, the Company capitalized $973 million of costs to obtain revenue contracts and amortized $768 million to marketing and sales expense. During the same period a year ago, the Company capitalized $543 million of costs to obtain revenue contracts and amortized $647 million to marketing and sales expense. During the three months ended April 30, 2020, the Company offered its direct sales force a partial minimum commission guarantee that would pay the greater of actual commissions earned or a fixed amount of their variable compensation that would have been otherwise paid during the three months ended April 30, 2020 if incremental new business was not impacted by the COVID-19 pandemic. As these payments were guaranteed, and not a cost to obtain a revenue contract, the amounts were immediately expensed and are reflected in the Company’s condensed consolidated statement of operations for the nine months ended October 31, 2020. Costs capitalized to obtain a revenue contract, net on the Company's condensed consolidated balance sheets totaled $2.5 billion as of October 31, 2020 and $2.3 billion as of January 31, 2020. There were no impairments of costs to obtain revenue contracts for the three and nine months ended October 31, 2020 and 2019, respectively. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents are stated at fair value. Marketable Securities The Company considers all of its marketable debt securities as available for use in current operations, including those with maturity dates beyond one year, and therefore classifies these securities within current assets on the condensed consolidated balance sheets. Securities are classified as available for sale and are carried at fair value, with the change in unrealized gains and losses, net of tax, reported as a separate component on the condensed consolidated statements of comprehensive income until realized. Fair value is determined based on quoted market rates when observable or utilizing data points that are observable, such as quoted prices, interest rates and yield curves. Securities with an amortized cost basis in excess of estimated fair value are assessed to determine what amount of the excess, if any, is caused by expected credit losses, as required by new accounting pronouncement, Accounting Standards Update No. 2016-13 (“ASU 2016-13”), discussed in further detail below. Expected credit losses on securities are recognized in other income (expense), net on the condensed consolidated statements of operations, and any remaining unrealized losses, net of taxes, are included in accumulated other comprehensive loss in stockholders' equity. For the purposes of computing realized and unrealized gains and losses, the cost of securities sold is based on the specific-identification method. Interest on securities classified as available for sale is included as a component of investment income. Strategic Investments The Company holds strategic investments in privately held debt and equity securities and publicly held equity securities in which the Company does not have a controlling interest. Privately held equity securities which the Company does not have a controlling financial interest in but does exercise significant influence over the investee are accounted for under the equity method. Privately held equity securities not accounted for under the equity method are recorded at cost and adjusted for observable transactions for same or similar investments of the same issuer (referred to as the measurement alternative) or impairment. All gains and losses on privately held equity securities, realized and unrealized, are recorded through gains on strategic investments, net on the condensed consolidated statement of operations. Privately held debt securities are recorded at fair value with changes in fair value recorded through accumulated other comprehensive income on the condensed consolidated balance sheet. Valuations of privately held securities are inherently complex due to the lack of readily available market data and require the Company's use of judgment. The carrying value is not adjusted for the Company's privately held equity securities if there are no observable price changes in a same or similar security from the same issuer or if there are no identified events or changes in circumstances that may indicate impairment, as discussed below. In determining the estimated fair value of its strategic investments in privately held companies, the Company utilizes the most recent data available to the Company. The Company assesses its privately held debt and equity securities in its strategic investment portfolio at least quarterly for impairment. The Company’s impairment analysis encompasses an assessment of both qualitative and quantitative factors including the investee's financial metrics, market acceptance of the investee's product or technology and the rate at which the investee is using its cash. If the investment is considered impaired, the Company recognizes an impairment through the condensed consolidated statement of operations and establishes a new carrying value for the investment. Publicly held equity securities are measured at fair value with changes recorded through gains on strategic investments, net on the condensed consolidated statement of operations. Derivative Financial Instruments The Company enters into foreign currency derivative contracts with financial institutions to reduce foreign exchange risk. The Company uses forward currency derivative contracts to minimize the Company’s exposure to balances primarily denominated in the Euro, British Pound Sterling, Japanese Yen, Canadian Dollar and Australian Dollar. The Company’s foreign currency derivative contracts, which are not designated as hedging instruments, are used to reduce the exchange rate risk associated primarily with intercompany receivables and payables. The Company’s derivative financial instruments program is not designated for trading or speculative purposes. The Company generally enters into master netting arrangements with the financial institutions with which it contracts for such derivative contracts, which permit net settlement of transactions with the same counterparty, thereby reducing credit-related losses in the event of the financial institutions' nonperformance. Outstanding foreign currency derivative contracts are recorded at fair value on the condensed consolidated balance sheets. Foreign currency derivative contracts are marked-to-market at the end of each reporting period with gains and losses recognized as other expense to offset the gains or losses resulting from the settlement or remeasurement of the underlying foreign currency denominated receivables and payables. While the contract or notional amount is often used to express the volume of foreign currency derivative contracts, the amounts potentially subject to credit risk are generally limited to the amounts, if any, by which the counterparties’ obligations under the agreements exceed the obligations of the Company to the counterparties. Fair Value Measurement The Company measures its cash and cash equivalents, marketable securities and foreign currency derivative contracts at fair value. In addition, the Company measures its strategic investments, including its publicly held equity securities, privately held debt securities and privately held equity securities for which there has been an observable price change in a same or similar security, at fair value. The additional disclosures regarding the Company’s fair value measurements are included in Note 5 “Fair Value Measurement.” Property and Equipment Property and equipment are stated at cost. Depreciation is calculated on a straight-line basis over the estimated useful lives of those assets as follows: Computers, equipment and software 3 to 9 years Furniture and fixtures 5 years Leasehold improvements Shorter of the estimated lease term or 10 years Buildings and building improvements 10 to 40 years When assets are retired or otherwise disposed of, the cost and accumulated depreciation and amortization are removed from their respective accounts and any loss on such retirement is reflected in operating expenses. Capitalized Software Costs The Company capitalizes costs related to its enterprise cloud computing services and certain projects for internal use incurred during the application development stage. Costs related to preliminary project activities and post implementation activities are expensed as incurred. Internal-use software is amortized on a straight-line basis over its estimated useful life, which is generally three to five years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Intangible Assets Acquired through Business Combinations Intangible assets are amortized over their estimated useful lives. Each period, the Company evaluates the estimated remaining useful life of its intangible assets and whether events or changes in circumstances warrant a revision to the remaining period of amortization. Management tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Impairment Assessment The Company evaluates intangible assets and long-lived assets for possible impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. This includes but is not limited to significant adverse changes in business climate, market conditions, or other events that indicate an asset's carrying amount may not be recoverable. Recoverability of these assets is measured by comparing the carrying amount of each asset to the future undiscounted cash flows the asset is expected to generate. If the undiscounted cash flows used in the test for recoverability are less than the carrying amount of these assets, the carrying amount of such assets is reduced to fair value. The Company evaluates and tests the recoverability of its goodwill for impairment at least annually during its fourth quarter of each fiscal year or more often if and when circumstances indicate that goodwill may not be recoverable. There were no material impairments of intangible assets, long-lived assets or goodwill during the nine months ended October 31, 2020 and 2019, respectively. Business Combinations The Company uses its best estimates and assumptions to assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. The Company’s estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions, tax-related valuation allowances and pre-acquisition contingencies are initially recorded in connection with a business combination as of the acquisition date. The Company continues to collect information and reevaluates these estimates and assumptions quarterly and records any adjustments to the Company’s preliminary estimates to goodwill provided that the Company is within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s condensed consolidated statement of operations. In the event the Company acquires an entity with which the Company has a preexisting relationship, the Company will generally recognize a gain or loss to settle that relationship as of the acquisition date within operating income on the condensed consolidated statements of operations. In the event that the Company acquires an entity in which the Company previously held a strategic investment, the difference between the fair value of the shares as of the date of the acquisition and the carrying value of the strategic investment is recorded as a gain or loss and recorded within net gains (or losses) on strategic investments in the condensed consolidated statement of operations. Leases The Company determines if an arrangement is a lease at inception and classifies its leases at commencement. Operating leases are included in operating lease right-of-use (“ROU”) assets and current and noncurrent operating lease liabilities on the Company’s condensed consolidated balance sheets. Finance leases are included in property and equipment, accrued expenses and other liabilities, and other noncurrent liabilities on the Company’s condensed consolidated balance sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and the corresponding lease liabilities represent its obligation to make lease payments arising from the lease. Lease ROU assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The lease ROU asset is reduced for tenant incentives. As the Company’s leases typically do not provide an implicit rate, the net present value of future minimum lease payments is determined using the Company’s incremental borrowing rate. The Company's incremental borrowing rate is an estimate of the interest rate the Company would have to pay to borrow on a collateralized basis with similar terms and payments, in an economic environment where the leased asset is located. The Company’s lease terms may include options to extend or terminate the lease. These options are reflected in the ROU asset and lease liability when it is reasonably certain that the Company will exercise the option. The Company reassesses the lease term if and when a significant event or change in circumstances occurs within the control of the Company, such as construction of significant leasehold improvements that are expected to have economic value when the option becomes exercisable. Lease expenses for minimum lease payments for operating leases are recognized on a straight-line basis over the lease term. Amortization expense of the ROU asset for finance leases is recognized on a straight-line basis over the lease term and interest expense for finance leases is recognized based on the incremental borrowing rate. The Company has lease agreements which contain both lease and non-lease components, which it has elected to combine for all asset classes. In addition, the Company does not recognize ROU assets or lease liabilities for leases with a term of 12 months or less for any asset classes. On the lease commencement date the Company establishes assets and liabilities for the present value of estimated future costs to retire long-lived assets at the termination or expiration of a lease. Such assets are amortized over the lease term to operating expense. The Company additionally has entered into subleases for unoccupied leased office space. Any impairments to th

Americas revenue attributed to the United States was approximately 96 percent during the three and nine months ended October 31, 2020 and 2019, respectively. No other country represented more than ten percent of total revenue during the three and nine months ended October 31, 2020 and 2019, respectively. Contract Balances Contract Assets As described in Note 1, subscription and support revenue is generally recognized ratably over the contract term beginning on the commencement date of each contract. License revenue is recognized as the licenses are delivered. The Company records a contract asset when revenue recognized on a contract exceeds the billings. The Company's standard billing terms are annual in advance. Contract assets were $574 million as of October 31, 2020 as compared to $449 million as of January 31, 2020, and are included in prepaid expenses and other current assets on the condensed consolidated balance sheet. Impairments of contract assets were immaterial during the three and nine months ended October 31, 2020 and 2019, respectively. Unearned Revenue Unearned revenue represents amounts that have been invoiced in advance of revenue recognition and is recognized as revenue when transfer of control to customers has occurred or services have been provided. The unearned revenue balance does not represent the total contract value of annual or multi-year, non-cancelable subscription agreements. The Company generally invoices customers in annual installments. The unearned revenue balance is influenced by several factors, including seasonality, the compounding effects of renewals, invoice duration, invoice timing, dollar size and new business linearity within the quarter. The change in unearned revenue was as follows (in millions): Three Months Ended October 31, Nine Months Ended October 31, 2020 2019 2020 2019 Unearned revenue, beginning of period $ 8,711 $ 7,142 $ 10,662 $ 8,564 Billings and other (1) 4,561 3,886 12,498 9,996 Contribution from contract asset 66 61 125 112 Revenue recognized ratably over time (4,911) (4,047) (14,021) (11,270) Revenue recognized over time as delivered (192) (184) (573) (530) Revenue recognized at a point in time (316) (282) (841) (447) Unearned revenue from business combinations 4 282 73 433 Unearned revenue, end of period $ 7,923 $ 6,858 $ 7,923 $ 6,858 (1) Other includes, for example, the impact of foreign currency translation. Revenue recognized ratably over time is generally billed in advance and includes Cloud Services, the related support and advisory services. The majority of revenue recognized for these services is from the beginning of period unearned revenue balance. Revenue recognized over time as delivered includes professional services billed on a time and materials basis, fixed fee professional services and training classes that are primarily billed, delivered and recognized within the same reporting period. Revenue recognized at a point in time substantially consists of on-premises software licenses. Remaining Performance Obligation Remaining performance obligation represents contracted revenue that has not yet been recognized and includes unearned revenue and unbilled amounts that will be recognized as revenue in future periods. Transaction price allocated to the remaining performance obligation is influenced by several factors, including seasonality, the timing of renewals, the timing of software license deliveries, average contract terms and foreign currency exchange rates. Remaining performance obligation is also impacted by acquisitions. Unbilled portions of the remaining performance obligation denominated in foreign currencies are revalued each period based on the period end exchange rates. Unbilled portions of the remaining performance obligation are subject to future economic risks including bankruptcies, regulatory changes and other market factors. The Company excludes amounts related to performance obligations that are billed and recognized as they are delivered. This primarily consists of professional services contracts that are on a time-and-materials basis. The majority of the Company's noncurrent remaining performance obligation is expected to be recognized in the next 13 to 36 months. Remaining performance obligation consisted of the following (in billions): Current Noncurrent Total As of October 31, 2020 $ 15.3 $ 15.0 $ 30.3 As of January 31, 2020 $ 15.0 $ 15.8 $ 30.8

The Company does not believe any of the unrealized losses represent an indication of credit loss based on its evaluation of available evidence as of October 31, 2020. The Company does not intend to sell its investments in a loss position and it is not more likely than not that the Company will be required to sell the investments before recovery of the investment’s amortized basis. No credit allowances were recorded as of October 31, 2020. The Company expects to receive the full principal and interest on all of these marketable securities. Investment Income Investment income consists of interest income, realized gains and realized losses on the Company’s cash, cash equivalents and marketable securities.

In February 2020, the Company made a strategic investment of $150 million in cash for preferred shares of a technology company in a preferred stock financing. The investment was accounted for using the measurement alternative. In June 2020, the Company made a strategic investment of $100 million in cash for preferred shares of a different technology company in a preferred stock financing. The investment was accounted for using the measurement alternative. In July 2020, one of the Company’s investments, which was previously accounted for under the measurement alternative, completed its initial public offering (“IPO”), resulting in a change of accounting methodology to fair value and the recognition of an unrealized loss of $92 million for the three months ended October 31, 2020 and an unrealized gain of $525 million for the nine months ended October 31, 2020, which is reflected in the table below. The investment is subject to a lock-up agreement in which the Company’s ability to sell is restricted until January 2021. As of October 31, 2020, the Company’s carrying value of this investment was $759 million. In September 2020, one of the Company’s investments, which was previously accounted for under the measurement alternative, completed its IPO which resulted in a change of accounting methodology to fair value. Concurrent with the IPO, the Company invested an additional $250 million. As of October 31, 2020, the Company recognized an unrealized gain of $1.1 billion on this investment, which is reflected in the table below. The investment concurrent with the IPO is subject to a lock-up agreement in which the Company’s ability to sell is restricted until September 2021, while the remainder of the Company’s investment is subject to a lock-up agreement until March 2021. As of October 31, 2020, the Company’s carrying value of this investment was $1.5 billion. Since the adoption of Accounting Standards Update No. 2016-01 (“ASU 2016-01”), “Financial Instrument-Overall (Subtopic 825-10)” on February 1, 2018, cumulative impairments and downward adjustments were $184 million and cumulative upward adjustments were $540 million through October 31, 2020. Gains on strategic investments, net The components of gains and losses on strategic investments are presented below (in millions): 3 Three Months Ended October 31, Nine Months Ended October 31, 2020 2019 2020 2019 Unrealized gains (losses) recognized on publicly traded equity securities, net $ 997 $ (84) $ 1,620 $ 132 Unrealized gains recognized on privately held equity securities, net 25 77 1 199 Realized gains on sales of equity securities, net 11 14 299 76 Gains (losses) on debt securities, net 3 (1) (10) (11) Gains on strategic investments, net $ 1,036 $ 6 $ 1,910 $ 396 Realized gains on sales of equity securities, net reflects the difference between the sale proceeds and the carrying value of the equity security at the beginning of the period or the purchase date, if later. The cumulative net realized gain, measured as the sale price less the initial purchase price, for securities that were exited during the three and nine months ended October 31, 2020 was $18 million and $545 million, respectively. Cumulative net realized gains for the nine months ended October 31, 2020 includes approximately $147 million related to the Company’s acquisition of Vlocity in June 2020. See Note 6 “Business Combinations” for additional details on the acquisition. Cumulative net realized gains for the nine months ended October 31, 2020 also includes gains related to the Company’s sales of two of its publicly traded investments resulting in a realized gain of $222 million, and a cumulative net gain of $314 million. Net unrealized gains recognized in the three and nine months ended October 31, 2020 for strategic investments still held as of October 31, 2020 were $1.0 billion and $1.6 billion, respectively. These include approximately $8 million and $99 million of impairments on its privately held equity and debt securities during the three and nine months ended October 31, 2020, respectively.

Fair Value Measurement	Oct. 31, 2020
Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement The Company uses a three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: Level 1. Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2. Significant other inputs that are directly or indirectly observable in the marketplace. Level 3. Significant unobservable inputs which are supported by little or no market activity. All of the Company’s cash equivalents, marketable securities and foreign currency derivative contracts are classified within Level 1 or Level 2 because the Company’s cash equivalents, marketable securities and foreign currency derivative contracts are valued using quoted market prices or alternative pricing sources and models utilizing observable market inputs. The following table presents information about the Company’s assets and liabilities that are measured at fair value as of October 31, 2020 and indicates the fair value hierarchy of the valuation (in millions): Description Quoted Prices in Significant Other Significant Balance as of Cash equivalents (1): Time deposits $ 0 $ 1,055 $ 0 $ 1,055 Money market mutual funds 1,120 0 0 1,120 Marketable securities: Corporate notes and obligations 0 3,253 0 3,253 U.S. treasury securities 0 164 0 164 Mortgage backed obligations 0 407 0 407 Asset backed securities 0 1,143 0 1,143 Municipal securities 0 313 0 313 Foreign government obligations 0 89 0 89 U.S. agency obligations 0 101 0 101 Covered bonds 0 298 0 298 Strategic investments: Publicly held equity securities 2,261 0 0 2,261 Foreign currency derivative contracts (2) 0 24 0 24 Total assets $ 3,381 $ 6,847 $ 0 $ 10,228 Liabilities: Foreign currency derivative contracts (3) 0 41 0 41 Total liabilities $ 0 $ 41 $ 0 $ 41 ___________ (1) Included in “cash and cash equivalents” in the accompanying condensed consolidated balance sheet as of October 31, 2020, in addition to $1.5 billion of cash.

Strategic investments measured and recorded at fair value on a non-recurring basis The Company's privately held debt and equity securities and equity method investments are recorded at fair value on a non-recurring basis. The estimation of fair value for these investments requires the use of significant unobservable inputs, and as a result, the Company classifies these assets as Level 3 within the fair value hierarchy. For example, the Company's privately held equity securities that have been remeasured are classified within Level 3 in the fair value hierarchy because the value is based on valuation methods using the observable transaction price and other unobservable inputs including the volatility, rights, and obligations of the securities the Company holds. The Company's privately held debt and equity securities and equity method investments amounted to $1.7 billion as of October 31, 2020 and $1.6 billion as of January 31, 2020.

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity The fair value of the Company’s stock options and ESPP shares was estimated on the date of grant and the first day of the ESPP purchase period, respectively, using the Black-Scholes option pricing model. The weighted-average fair value per share for stock options grants, excluding assumed awards, was $59.54 and $40.52 in the three and nine months ended October 31, 2020, respectively compared to $35.31 and $39.65 in the three and nine months ended October 31, 2019, respectively. ESPP assumptions and the related fair value per share table are disclosed in the three month period in which there is ESPP activity, such as an ESPP purchase. The Company's ESPP allows for two purchases during the fiscal year, one during the second quarter and one during the fourth quarter. The estimated life of the ESPP will be based on the two purchase periods within each offering period. The weighted-average fair value per share for ESPP shares was $53.64 in the three months ended October 31, 2020.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Effective Tax Rate The Company computes its year-to-date provision for income taxes by applying the estimated annual effective tax rate to year-to-date pretax income or loss and adjusts the provision for discrete tax items recorded in the period. For the nine months ended October 31, 2020, the Company reported a tax benefit of $1.7 billion on a pretax income of $2.1 billion, which resulted in a negative effective tax rate of 78 percent. The Company’s effective tax rate differs from the U.S. statutory rate of 21 percent primarily due to a one-time discrete tax benefit of $2.0 billion recorded during the three months ended July 31, 2020. The Company changed its international corporate structure, which included the consolidation of certain intangible property in Ireland resulting in a net tax benefit related to foreign deferred tax assets. The Company believes that it is more likely than not the deferred tax assets will be realized in Ireland. For the nine months ended October 31, 2019, the Company reported a tax provision of $336 million on a pretax income of $710 million, which resulted in an effective tax rate of 47 percent. The Company's effective tax rate differs from the U.S. statutory rate of 21 percent primarily due to profitable jurisdictions outside of the United States subject to tax rates greater than 21 percent and certain effects from acquisitions, offset by excess tax benefits from stock-based compensation. Unrecognized Tax Benefits and Other Considerations The Company records liabilities related to its uncertain tax positions. Tax positions for the Company and its subsidiaries are subject to income tax audits by multiple tax jurisdictions throughout the world. Certain prior year tax returns are currently being examined by various taxing authorities in countries including the United States, France, Germany and Japan. The Company believes that it has provided adequate reserves for its income tax uncertainties in all open tax years. As the outcome of the tax audits cannot be predicted with certainty, if any issues arising in the Company's tax audits progress in a manner inconsistent with management's expectations, the Company could adjust its provision for income taxes in the future. In addition, the Company anticipates it is reasonably possible that a decrease of its unrecognized tax benefits up to approximately $6 million may occur in the next 12 months, as the applicable statutes of limitations lapse, ongoing examinations are completed, or tax positions meet the conditions of being effectively settled.

Diluted earnings per share is computed by giving effect to all potential weighted average dilutive common stock, including options and restricted stock units. The dilutive effect of outstanding awards and convertible securities is reflected in diluted earnings per share by application of the treasury stock method.

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings and Claims	Legal Proceedings and Claims In the ordinary course of business, the Company is or may be involved in various legal or regulatory proceedings, claims or purported class actions related to alleged infringement of third-party patents and other intellectual property rights, commercial, corporate and securities, labor and employment, wage and hour and other claims. The Company has been, and may in the future be put on notice or sued by third parties for alleged infringement of their proprietary rights, including patent infringement. In general, the resolution of a legal matter could prevent the Company from offering its service to others, could be material to the Company’s financial condition or cash flows, or both, or could otherwise adversely affect the Company’s operating results. The Company makes a provision for a liability relating to legal matters when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, estimated settlements, legal rulings, advice of legal counsel and other information and events pertaining to a particular matter. The outcomes of legal proceedings and other contingencies are, however, inherently unpredictable and subject to significant uncertainties. At this time, the Company is not able to reasonably estimate the amount or range of possible losses in excess of any amounts accrued, including losses that could arise as a result of application of non-monetary remedies, with respect to the contingencies it faces, and the Company’s estimates may not prove to be accurate. In management’s opinion, resolution of all current matters is not expected to have a material adverse impact on the Company’s condensed consolidated results of operations, cash flows or financial position. However, depending on the nature and timing of any such dispute or other contingency, an unfavorable resolution of a matter could materially affect the Company’s current or future results of operations or cash flows, or both, in a particular quarter. Tableau Litigation In July and August 2017, two substantially similar securities class action complaints were filed against Tableau and two of its now former executive officers. The first complaint was filed in the U.S. District for the Southern District of New York (the “Scheufele Action”). The second complaint was filed in the U.S. District Court for the Western District of Washington and was voluntarily dismissed on October 17, 2017. In December 2017, the lead plaintiff in the Scheufele Action filed an amended complaint, which alleged that between February 5, 2015 and February 4, 2016, Tableau and certain of its executive officers violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the "Exchange Act") and Rule 10b-5 promulgated thereunder, in connection with statements regarding Tableau’s business and operations by allegedly failing to disclose, among other things, that product launches and software upgrades by competitors were negatively impacting Tableau’s competitive position and profitability. The amended complaint sought unspecified damages, interest, attorneys’ fees and other costs. In February 2018, the lead plaintiff filed a second amended complaint (the "SAC"), which contains substantially similar allegations as the amended complaint, and added as defendants two more of Tableau’s now former executive officers and directors. Defendants filed a motion to dismiss the SAC in March 2018, which was denied in February 2019.

Related Party Transactions [Abstract]
Related-Party Transactions	Related-Party Transactions In January 1999, the Salesforce Foundation (the “Foundation”) was chartered on an idea of leveraging the Company’s people, technology and resources to help improve communities around the world. The Company calls this integrated philanthropic approach the 1-1-1 model. The Company’s Chair is the chair of the Foundation and holds one of the three Foundation board seats. The Company does not control the Foundation’s activities, and accordingly, the Company does not consolidate the Foundation’s statement of activities with its financial results. Since the Foundation’s inception, the Company has provided at no charge certain resources to the Foundation including general administrative support. The value of these resources to the Foundation has not been material. As a result of the fiscal 2020 business combination with Salesforce.org, which was a related party, the Company agreed to use its best efforts to make charitable cash commitments of up to $5 million quarterly to the Foundation for ten years beginning in the third quarter of fiscal 2020.

Accounting Policies [Abstract]
Fiscal Year	Fiscal Year The Company’s fiscal year ends on January 31. References to fiscal 2021, for example, refer to the fiscal year ending January 31, 2021.
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated balance sheet as of October 31, 2020 and the condensed consolidated statements of operations, condensed consolidated statements of comprehensive income (loss), condensed consolidated statements of stockholders' equity and condensed consolidated statements of cash flows for the three and nine months ended October 31, 2020 and 2019 are unaudited. These financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the financial information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of the Company’s management, the unaudited condensed consolidated financial statements include all adjustments necessary for the fair presentation of the Company’s balance sheet as of October 31, 2020, and its results of operations, including its comprehensive income (loss), stockholders' equity and its cash flows for the three and nine months ended October 31, 2020 and 2019. All adjustments are of a normal recurring nature. The results for the three and nine months ended October 31, 2020 are not necessarily indicative of the results to be expected for any subsequent quarter or for the fiscal year ending January 31, 2021. These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2020, filed with the Securities and Exchange Commission (the “SEC”) on March 5, 2020.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions in the Company’s condensed consolidated financial statements and notes thereto. Significant estimates and assumptions made by management include the determination of: • the fair value of assets acquired and liabilities assumed for business combinations; • the standalone selling price (“SSP”) of performance obligations for revenue contracts with multiple performance obligations; • the valuation of privately-held strategic investments, including impairments; • the recognition, measurement and valuation of current and deferred income taxes and uncertain tax positions; • the average period of benefit associated with costs capitalized to obtain revenue contracts; • the useful lives of intangible assets; and • the fair value of certain stock awards issued. Actual results could differ materially from those estimates. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the result of which forms the basis for making judgments about the carrying values of assets and liabilities. In December 2019, the novel coronavirus and resulting disease (“COVID-19”) was reported and in March 2020 the World Health Organization declared it a pandemic. The extent of the impact of the COVID-19 pandemic on the Company’s operational and financial performance depends on certain developments, including the duration of the pandemic, impact on the
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Segments	Segments The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”), in deciding how to allocate resources and assess performance. Over the past few years, the Company has completed a number of acquisitions. These acquisitions have allowed the Company to expand its offerings, presence and reach in various market segments of the enterprise cloud computing market.
Concentrations of Credit Risk, Significant Customers and Investments	Concentrations of Credit Risk, Significant Customers and Investments The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities and accounts receivable. Collateral is not required for accounts receivable. The Company maintains an allowance for its doubtful accounts receivable due to estimated credit losses. This allowance is based upon historical loss patterns, the number of days that billings are past due, an evaluation of the potential risk of loss associated with delinquent accounts and current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss patterns. The Company records the allowance against bad debt expense through the condensed consolidated statement of operations up to the amount of revenues recognized to date. Any incremental allowance is recorded as an offset to unearned revenue on the condensed consolidated balance sheet. Receivables are written-off and charged against the recorded allowance when the Company has exhausted collection efforts without success. No single customer accounted for more than five percent of accounts receivable at October 31, 2020 and January 31, 2020. No single customer accounted for five percent or more of total revenue during the nine months ended October 31, 2020 and 2019. As of October 31, 2020 and January 31, 2020, assets located outside the Americas were 13 percent and 12 percent of total assets, respectively. As of October 31, 2020 and January 31, 2020, assets located in the United States were 85 percent and 87 percent of total assets, respectively. The Company is also exposed to concentrations of risk in its strategic investment portfolio. As of October 31, 2020, the Company held one publicly traded investment with a carrying value that was individually greater than 35 percent of its total strategic investments, one publicly traded investment with a carrying value that was individually approximately 20 percent of its total strategic investments and one privately held investment individually greater than five percent of its total strategic investments. As of January 31, 2020, the Company held five investments that were individually greater than five percent of its total strategic investments, of which one was publicly traded and four were privately held. The publicly traded investments held as of October 31, 2020 are different than the publicly traded investment that was held as of January 31, 2020.
Revenue Recognition	Revenue Recognition The Company derives its revenues from two sources: (1) subscription revenues, which are comprised of subscription fees from customers accessing the Company’s enterprise cloud computing services (collectively, “Cloud Services”), software licenses, and from customers paying for additional support beyond the standard support that is included in the basic subscription fees; and (2) related professional services such as process mapping, project management and implementation services. Other revenue consists primarily of training fees. Revenue is recognized upon transfer of control of promised products and services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. If the consideration promised in a contract includes a variable amount, for example, overage fees, contingent fees or service level penalties, the Company includes an estimate of the amount it expects to receive for the total transaction price if it is probable that a significant reversal of cumulative revenue recognized will not occur. The Company determines the amount of revenue to be recognized through the application of the following steps: • Identification of the contract, or contracts, with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when or as the Company satisfies the performance obligations. The Company’s subscription service arrangements are non-cancelable and do not contain refund-type provisions. Subscription and Support Revenues Subscription and support revenues are comprised of fees that provide customers with access to Cloud Services, software licenses and related support and updates during the term of the arrangement. Cloud Services allow customers to use the Company's multi-tenant software without taking possession of the software. Revenue is generally recognized ratably over the contract term. With the May 2018 acquisition of MuleSoft, Inc. (“MuleSoft”) and the August 2019 acquisition of Tableau Software, Inc. (“Tableau”), subscription and support revenues also includes revenues associated with software licenses. These licenses for on-premises software provide the customer with a right to use the software as it exists when made available. Customers purchase these term licenses through a subscription. Revenues from distinct licenses are generally recognized upfront when the software is made available to the customer. In cases where the Company allocates revenue to software updates and support revenue, the allocated revenue is recognized as the updates are provided, which is generally ratably over the contract term. The Company typically invoices its customers annually. Typical payment terms provide that customers pay within 30 days of invoice. Amounts that have been invoiced are recorded in accounts receivable and in unearned revenue or revenue, depending on whether transfer of control to customers has occurred. Professional Services and Other Revenues The Company’s professional services contracts are either on a time and materials, fixed fee or subscription basis. These revenues are recognized as the services are rendered for time and materials contracts, on a proportional performance basis for fixed price contracts or ratably over the contract term for subscription professional services contracts. Training revenues are recognized as the services are performed. Significant Judgments - Contracts with Multiple Performance Obligations The Company enters into contracts with its customers that may include promises to transfer multiple Cloud Services, software licenses, premium support and professional services. A performance obligation is a promise in a contract with a customer to transfer products or services that are distinct. Determining whether products and services are distinct performance obligations that should be accounted for separately or combined as one unit of accounting may require significant judgment. Cloud Services and software licenses are distinct because such offerings are often sold separately. In determining whether professional services are distinct, the Company considers the following factors for each professional services agreement: availability of the services from other vendors, the nature of the professional services, the timing of when the professional services contract was signed in comparison to the subscription start date and the contractual dependence of the service on the customer’s satisfaction with the professional services work. To date, the Company has concluded that professional services included in contracts with multiple performance obligations are distinct. The Company allocates the transaction price to each performance obligation on a relative SSP basis. The SSP is the price at which the Company would sell a promised product or service separately to a customer. Judgment is required to determine the SSP for each distinct performance obligation. The Company determines SSP by considering its overall pricing objectives and market conditions. Significant pricing practices taken into consideration include the Company’s discounting practices, the size and volume of the Company’s transactions, the customer demographic, the geographic area where services are sold, price lists, the Company's go-to-market strategy, historical sales and contract prices. In instances where the Company does not sell or price a product or service separately, the Company determines relative fair value using information that may include market conditions or other observable inputs. As the Company’s go-to-market strategies evolve, the Company may modify its pricing practices in the future, which could result in changes to SSP. In certain cases, the Company is able to establish SSP based on observable prices of products or services sold or priced separately in comparable circumstances to similar customers. The Company uses a single amount to estimate SSP when it has observable prices. If SSP is not directly observable, for example when pricing is highly variable, the Company uses a range of SSP. The Company determines the SSP range using information that may include pricing practices or other observable inputs. The Company typically has more than one SSP for individual products and services due to the stratification of those products and services by customer size and geography. Costs Capitalized to Obtain Revenue Contracts The Company capitalizes incremental costs of obtaining non-cancelable Cloud Services subscription, ongoing Cloud Services support and license support revenue contracts. For contracts with on-premises software licenses where revenue is recognized upfront when the software is made available to the customer, costs allocable to those licenses are expensed as they are incurred. Capitalized amounts consist primarily of sales commissions paid to the Company’s direct sales force. Capitalized amounts also include (1) amounts paid to employees other than the direct sales force who earn incentive payouts under annual compensation plans that are tied to the value of contracts acquired, (2) commissions paid to employees upon renewals of subscription and support contracts, (3) the associated payroll taxes and fringe benefit costs associated with the payments to the Company’s employees, and (4) to a lesser extent, success fees paid to partners in emerging markets where the Company has a limited presence. Costs capitalized related to new revenue contracts are amortized on a straight-line basis over four years, which, although longer than the typical initial contract period, reflects the average period of benefit, including expected contract renewals. In arriving at this average period of benefit, the Company evaluated both qualitative and quantitative factors which included the estimated life cycles of its offerings and its customer attrition. Additionally, the Company amortizes capitalized costs for renewals and success fees paid to partners over two years. The capitalized amounts are recoverable through future revenue streams under all non-cancelable customer contracts. The Company periodically evaluates whether there have been any changes in its business, the market conditions in which it operates or other events which would indicate that its amortization period should be changed or if there are potential indicators of impairment. Amortization of capitalized costs to obtain revenue contracts is included in marketing and sales expense in the accompanying condensed consolidated statements of operations.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents are stated at fair value.
Marketable Securities	Marketable Securities The Company considers all of its marketable debt securities as available for use in current operations, including those with maturity dates beyond one year, and therefore classifies these securities within current assets on the condensed consolidated balance sheets. Securities are classified as available for sale and are carried at fair value, with the change in unrealized gains and losses, net of tax, reported as a separate component on the condensed consolidated statements of comprehensive income until realized. Fair value is determined based on quoted market rates when observable or utilizing data points that are observable, such as quoted prices, interest rates and yield curves. Securities with an amortized cost basis in excess of estimated fair value are assessed to determine what amount of the excess, if any, is caused by expected credit losses, as required by new accounting pronouncement, Accounting Standards Update No. 2016-13 (“ASU 2016-13”), discussed in further detail below. Expected credit losses on securities are recognized in other income (expense), net on the condensed consolidated statements of operations, and any remaining unrealized losses, net of taxes, are included in accumulated other comprehensive loss in stockholders' equity. For the purposes of computing realized and unrealized gains and losses, the cost of securities sold is based on the specific-identification method. Interest on securities classified as available for sale is included as a component of investment income.
Strategic Investments	Strategic Investments The Company holds strategic investments in privately held debt and equity securities and publicly held equity securities in which the Company does not have a controlling interest. Privately held equity securities which the Company does not have a controlling financial interest in but does exercise significant influence over the investee are accounted for under the equity method. Privately held equity securities not accounted for under the equity method are recorded at cost and adjusted for observable transactions for same or similar investments of the same issuer (referred to as the measurement alternative) or impairment. All gains and losses on privately held equity securities, realized and unrealized, are recorded through gains on strategic investments, net on the condensed consolidated statement of operations. Privately held debt securities are recorded at fair value with changes in fair value recorded through accumulated other comprehensive income on the condensed consolidated balance sheet. Valuations of privately held securities are inherently complex due to the lack of readily available market data and require the Company's use of judgment. The carrying value is not adjusted for the Company's privately held equity securities if there are no observable price changes in a same or similar security from the same issuer or if there are no identified events or changes in circumstances that may indicate impairment, as discussed below. In determining the estimated fair value of its strategic investments in privately held companies, the Company utilizes the most recent data available to the Company. The Company assesses its privately held debt and equity securities in its strategic investment portfolio at least quarterly for impairment. The Company’s impairment analysis encompasses an assessment of both qualitative and quantitative factors including the investee's financial metrics, market acceptance of the investee's product or technology and the rate at which the investee is using its cash. If the investment is considered impaired, the Company recognizes an impairment through the condensed consolidated statement of operations and establishes a new carrying value for the investment. Publicly held equity securities are measured at fair value with changes recorded through gains on strategic investments, net on the condensed consolidated statement of operations.
Derivative Financial Instruments	Derivative Financial Instruments The Company enters into foreign currency derivative contracts with financial institutions to reduce foreign exchange risk. The Company uses forward currency derivative contracts to minimize the Company’s exposure to balances primarily denominated in the Euro, British Pound Sterling, Japanese Yen, Canadian Dollar and Australian Dollar. The Company’s foreign currency derivative contracts, which are not designated as hedging instruments, are used to reduce the exchange rate risk associated primarily with intercompany receivables and payables. The Company’s derivative financial instruments program is not designated for trading or speculative purposes. The Company generally enters into master netting arrangements with the financial institutions with which it contracts for such derivative contracts, which permit net settlement of transactions with the same counterparty, thereby reducing credit-related losses in the event of the financial institutions' nonperformance. Outstanding foreign currency derivative contracts are recorded at fair value on the condensed consolidated balance sheets. Foreign currency derivative contracts are marked-to-market at the end of each reporting period with gains and losses recognized as other expense to offset the gains or losses resulting from the settlement or remeasurement of the underlying foreign currency denominated receivables and payables. While the contract or notional amount is often used to express the volume of foreign currency derivative contracts, the amounts potentially subject to credit risk are generally limited to the amounts, if any, by which the counterparties’ obligations under the agreements exceed the obligations of the Company to the counterparties.
Fair Value Measurement	Fair Value Measurement The Company measures its cash and cash equivalents, marketable securities and foreign currency derivative contracts at fair value. In addition, the Company measures its strategic investments, including its publicly held equity securities, privately held debt securities and privately held equity securities for which there has been an observable price change in a same or similar security, at fair value. The additional disclosures regarding the Company’s fair value measurements are included in Note 5 “Fair Value Measurement.”
Property and Equipment	Property and Equipment Property and equipment are stated at cost. Depreciation is calculated on a straight-line basis over the estimated useful lives of those assets as follows: Computers, equipment and software 3 to 9 years Furniture and fixtures 5 years Leasehold improvements Shorter of the estimated lease term or 10 years Buildings and building improvements 10 to 40 years When assets are retired or otherwise disposed of, the cost and accumulated depreciation and amortization are removed from their respective accounts and any loss on such retirement is reflected in operating expenses.
Capitalized Software Costs	Capitalized Software Costs The Company capitalizes costs related to its enterprise cloud computing services and certain projects for internal use incurred during the application development stage. Costs related to preliminary project activities and post implementation activities are expensed as incurred. Internal-use software is amortized on a straight-line basis over its estimated useful life, which is generally three to five years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.
Intangible Assets acquired through Business Combinations	Intangible Assets Acquired through Business Combinations Intangible assets are amortized over their estimated useful lives. Each period, the Company evaluates the estimated remaining useful life of its intangible assets and whether events or changes in circumstances warrant a revision to the remaining period of amortization. Management tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.
Impairment Assessment	Impairment Assessment The Company evaluates intangible assets and long-lived assets for possible impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. This includes but is not limited to significant adverse changes in business climate, market conditions, or other events that indicate an asset's carrying amount may not be recoverable. Recoverability of these assets is measured by comparing the carrying amount of each asset to the future undiscounted cash flows the asset is expected to generate. If the undiscounted cash flows used in the test for recoverability are less than the carrying amount of these assets, the carrying amount of such assets is reduced to fair value.
Business Combinations	Business Combinations The Company uses its best estimates and assumptions to assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. The Company’s estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions, tax-related valuation allowances and pre-acquisition contingencies are initially recorded in connection with a business combination as of the acquisition date. The Company continues to collect information and reevaluates these estimates and assumptions quarterly and records any adjustments to the Company’s preliminary estimates to goodwill provided that the Company is within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s condensed consolidated statement of operations. In the event the Company acquires an entity with which the Company has a preexisting relationship, the Company will generally recognize a gain or loss to settle that relationship as of the acquisition date within operating income on the condensed consolidated statements of operations. In the event that the Company acquires an entity in which the Company previously held a strategic investment, the difference between the fair value of the shares as of the date of the acquisition and the carrying value of the strategic investment is recorded as a gain or loss and recorded within net gains (or losses) on strategic investments in the condensed consolidated statement of operations.
Leases	Leases The Company determines if an arrangement is a lease at inception and classifies its leases at commencement. Operating leases are included in operating lease right-of-use (“ROU”) assets and current and noncurrent operating lease liabilities on the Company’s condensed consolidated balance sheets. Finance leases are included in property and equipment, accrued expenses and other liabilities, and other noncurrent liabilities on the Company’s condensed consolidated balance sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and the corresponding lease liabilities represent its obligation to make lease payments arising from the lease. Lease ROU assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The lease ROU asset is reduced for tenant incentives. As the Company’s leases typically do not provide an implicit rate, the net present value of future minimum lease payments is determined using the Company’s incremental borrowing rate. The Company's incremental borrowing rate is an estimate of the interest rate the Company would have to pay to borrow on a collateralized basis with similar terms and payments, in an economic environment where the leased asset is located. The Company’s lease terms may include options to extend or terminate the lease. These options are reflected in the ROU asset and lease liability when it is reasonably certain that the Company will exercise the option. The Company reassesses the lease term if and when a significant event or change in circumstances occurs within the control of the Company, such as construction of significant leasehold improvements that are expected to have economic value when the option becomes exercisable. Lease expenses for minimum lease payments for operating leases are recognized on a straight-line basis over the lease term. Amortization expense of the ROU asset for finance leases is recognized on a straight-line basis over the lease term and interest expense for finance leases is recognized based on the incremental borrowing rate. The Company has lease agreements which contain both lease and non-lease components, which it has elected to combine for all asset classes. In addition, the Company does not recognize ROU assets or lease liabilities for leases with a term of 12 months or less for any asset classes. On the lease commencement date the Company establishes assets and liabilities for the present value of estimated future costs to retire long-lived assets at the termination or expiration of a lease. Such assets are amortized over the lease term to operating expense. The Company additionally has entered into subleases for unoccupied leased office space. Any impairments to the ROU asset, leasehold improvements or other assets as a result of a sublease are recognized in the period the sublease is executed and recorded as an operating expense. Similar to other long-lived assets, management tests ROU assets for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. For leased assets, such circumstances would include subleases which do not fully recover the costs of the associated lease.
Stock-Based Expense	Stock-Based Expense Stock-based expenses related to stock options are measured based on grant date at fair value using the Black-Scholes option pricing model and restricted stock awards based on grant date at fair value using the closing stock price. The Company recognizes stock-based expenses related to stock options and restricted stock awards on a straight-line basis, net of estimated forfeitures, over the requisite service period of the awards, which is generally the vesting term of four years. Stock-based expenses related to the Company’s Amended and Restated 2004 Employee Stock Purchase Plan (“ESPP” or “2004 Employee Stock Purchase Plan”) are measured based on grant date at fair value using the Black-Scholes option pricing model. The Company recognizes stock-based expenses related to shares issued pursuant to the 2004 Employee Stock Purchase Plan on a straight-line basis over the offering period, which is 12 months. The ESPP allows employees to purchase shares of the Company's common stock at a 15 percent discount from the lower of the Company’s stock price on (i) the first day of the offering period or on (ii) the last day of the purchase period and also allows employees to reduce their percentage election once during a six month purchase period (December 15 and June 15 of each fiscal year), but not increase that election until the next one-year offering period. The ESPP also includes a re-set provision for the purchase price if the stock price on the purchase date is less than the stock price on the offering date. Stock-based expenses related to performance share grants, which are awarded to executive officers and other members of senior management, are measured based on grant date at fair value using a Monte Carlo simulation model and expensed on a straight-line basis, net of estimated forfeitures, over the service period of the awards, which is generally the vesting term of three years.
Income Taxes	Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on temporary differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax laws is recognized in the condensed consolidated statements of operations in the period that includes the enactment date. The Company’s tax positions are subject to income tax audits by multiple tax jurisdictions throughout the world. The Company recognizes the tax benefit of an uncertain tax position only if it is more likely than not that the position is sustainable upon examination by the taxing authority, solely based on its technical merits. The tax benefit recognized is measured as the largest amount of benefit which is greater than 50 percent likely to be realized upon settlement with the taxing authority. The Company recognizes interest accrued and penalties related to unrecognized tax benefits in the income tax provision. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts that are more likely than not expected to be realized based on the weighting of positive and negative evidence. Future realization of deferred tax assets ultimately depends on the existence of sufficient taxable income of the appropriate character (for example, ordinary income or capital gain) within the carryback or carryforward periods available under the applicable tax law. The Company regularly reviews the deferred tax assets for recoverability based on historical taxable income, projected future taxable income, the expected timing of the reversals of existing temporary differences and tax planning strategies. The Company’s judgments regarding future profitability may change due to many factors, including future market conditions and the ability to successfully execute its business plans. Should there be a change in the ability to recover deferred tax assets, the tax provision would increase or decrease in the period in which the assessment is changed.
Foreign Currency Translation	Foreign Currency Translation The functional currency of the Company’s major foreign subsidiaries is generally the local currency. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are recorded as a separate component on the condensed consolidated statement of comprehensive income. Foreign currency transaction gains and losses are included in other income in the condensed consolidated statement of operations for the period. All assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenues and expenses are translated at the average exchange rate during the period. Equity transactions are translated using historical exchange rates.
Warranties and Indemnification	Warranties and Indemnification The Company’s enterprise cloud computing services are typically warranted to perform in a manner consistent with general industry standards that are reasonably applicable and materially in accordance with the Company’s online help documentation under normal use and circumstances. The Company’s arrangements generally include certain provisions for indemnifying customers against liabilities if its products or services infringe a third party’s intellectual property rights. To date, the Company has not incurred any material costs as a result of such obligations and has not accrued any material liabilities related to such obligations in the accompanying condensed consolidated financial statements. The Company has also agreed to indemnify its directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlement amounts incurred by any of these persons in any action or proceeding to which any of those persons is, or is threatened to be, made a party by reason of the person’s service as a director or officer, including any action by the Company, arising out of that person’s services as the Company’s director or officer or that person’s services provided to any other company or enterprise at the Company’s request. The Company maintains director and officer insurance coverage that would generally enable the Company to recover a portion of any future amounts paid. The Company may also be subject to indemnification obligations by law with respect to the actions of its employees under certain circumstances and in certain jurisdictions.
New Accounting Pronouncements Adopted and Pending Adoption	New Accounting Pronouncement Adopted in Fiscal 2021 ASU 2016-13 In June 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost, and includes the Company's accounts receivable, certain financial instruments and contract assets. ASU 2016-13 replaces the prior incurred loss impairment model with an expected loss methodology, which results in more timely recognition of credit losses. Effective on February 1, 2020, the Company adopted the provisions and expanded disclosure requirements described in ASU 2016-13. The adoption of ASU 2016-13 was not material to the consolidated financial statements.
