Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Fiscal Year End. The Company’s fiscal year generally ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that every five or six years, the Company has a 53-week year. When a 53-week year occurs, the Company includes the additional week in the first quarter to realign fiscal quarters with calendar quarters. Fiscal 2019 and fiscal 2017 were 52-week years ending on November 2, 2019 and October 28, 2017, respectively. Fiscal 2018 was a 53-week year and ended on November 3, 2018. For presentation purposes, the consolidated financial statements and accompanying notes refer to the closest calendar month end. Fiscal 2020 will be a 52-week year. Principles of Consolidation. The consolidated financial statements include the accounts of the Company and all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated. Use of Estimates. To prepare financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP), management must make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and may result in material effects on the Company’s operating results and financial position. Segment Reporting. Effective in fiscal 2019, the Company realigned its business to evaluate the results of its Software Integrity business separately from the Company's traditional EDA and semiconductor IP business. The Chief Operating Decision Makers (CODMs) now regularly review disaggregated information for the following two reportable segments: (1) Semiconductor & System Design, which includes EDA tools, IP products, system integration solutions and other revenue categories, and (2) Software Integrity, which includes a comprehensive solution for building integrity—security, quality and compliance testing—into the customers’ software development lifecycle and supply chain. Synopsys' CODMs are the Company's two co-Chief Executive Officers. The Company's historical results have been recast to retrospectively reflect the change from one to two reportable segments. Foreign Currency Translation. The functional currency of the majority of the Company’s active foreign subsidiaries is the foreign subsidiary’s local currency. Assets and liabilities that are not denominated in the functional currency are remeasured into the functional currency with any related gain or loss recorded in earnings. The Company translates assets and liabilities of its non-U.S. dollar functional currency foreign operations into the U.S. dollar reporting currency at exchange rates in effect at the balance sheet date. The Company translates income and expense items of such foreign operations into the U.S. dollar reporting currency at average exchange rates for the period. Accumulated translation adjustments are reported in stockholders’ equity, as a component of accumulated other comprehensive income (loss). Foreign Currency Contracts. The Company operates internationally and is exposed to potentially adverse movements in currency exchange rates. The Company enters into hedges in the form of foreign currency forward contracts to reduce its exposure to foreign currency rate changes on non-functional currency denominated forecasted transactions and balance sheet positions. The assets or liabilities associated with the forward contracts are recorded at fair value in other current assets or accrued liabilities in the consolidated balance sheets. The accounting for gains and losses resulting from changes in fair value depends on the use of the foreign currency forward contract and whether it is designated and qualifies for hedge accounting. See Note 5. Financial Assets and Liabilities. Fair Values of Financial Instruments. The Company’s cash equivalents and foreign currency contracts are carried at fair value. The fair value of the Company’s accounts receivable and accounts payable approximates the carrying amount due to their short duration. Non-marketable equity securities are carried at cost, net of impairments. The Company performs periodic impairment analysis on these non-marketable equity securities. The carrying amount of the short-term debt approximates the estimated fair value. See Note 6. Fair Value Measures. Cash and Cash Equivalents. The Company classifies investments with original maturities of three months or less when acquired as cash equivalents. Concentration of Credit Risk. Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash equivalents, marketable securities, foreign currency contracts, and accounts receivable from trade customers. The Company maintains cash equivalents primarily in highly rated taxable and tax-exempt money market funds located in the U.S. and in various overseas locations. The Company sells its products worldwide primarily to customers in the global electronics market. The Company performs on-going credit evaluations of its customers’ financial condition and does not require collateral. The Company establishes reserves for potential credit losses and such losses have been within management’s expectations and have not been material in any year presented. Accounts Receivable, Net. The balances consist of accounts receivable billed and unbilled. Unbilled accounts receivable represent amounts recorded as revenue which will be invoiced within one year of the balance sheet date. The following table represents the components of accounts receivable, net:
| October 31,
| 2019 |  | 2018
| (in thousands)
Accounts receivable | $ | 524,766 |  |  | $ | 495,763 |
Unbilled accounts receivable | 38,175 |  |  | 64,067 |
Total accounts receivable | 562,941 |  |  | 559,830 |
Less allowance for doubtful accounts | (9,046 | ) |  | (5,613 | )
Total accounts receivable, net | $ | 553,895 |  |  | $ | 554,217 |
Allowance for Doubtful Accounts. Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains allowances for doubtful accounts to reduce the Company’s receivables to their estimated net realizable value. The Company provides a general reserve on all accounts receivable based on a review of customer accounts. The following table presents the changes in the allowance for doubtful accounts:
Fiscal Year | Balance at Beginning of Period |  | Provisions |  | Write-offs(1) |  | Balance at End of Period

(1) | Balances written off, net of recoveries.
Inventories. Inventories primarily include components and parts used in emulation and prototyping hardware systems. Inventory cost is computed using standard costs, which approximate actual costs, on a first-in, first-out basis and recorded at lower of cost or net realizable value. A charge is recorded to cost of product when inventory is determined to be in excess of anticipated demand or considered obsolete. Income Taxes. The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company accounts for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining whether it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. An uncertain tax position is considered effectively settled on completion of an examination by a taxing authority if certain other conditions are satisfied. Property and Equipment. Property and equipment is recorded at cost less accumulated depreciation. Assets, excluding land, are depreciated using the straight-line method over their estimated useful lives. Leasehold improvements are amortized using the straight-line method over the remaining term of the lease or the economic useful life of the asset, whichever is shorter. Depreciation expenses were $100.4 million, $72.8 million and $82.8 million in fiscal 2019, 2018 and 2017, respectively. Repair and maintenance costs are expensed as incurred and such costs were $52.5 million, $45.7 million and $40.6 million in fiscal 2019, 2018 and 2017, respectively. A summary of property and equipment, at cost less accumulated depreciation and amortization, as of October 31, 2019 and 2018 is as follows:
| October 31,
| 2019 |  | 2018
| (in thousands)
Computer and other equipment | $ | 678,901 |  |  | $ | 604,117 |
Buildings | 68,708 |  |  | 68,522 |
Furniture and fixtures | 72,437 |  |  | 61,070 |
Land | 18,849 |  |  | 18,849 |
Leasehold improvements | 273,985 |  |  | 183,430 |
| 1,112,880 |  |  | 935,988 |

Total | $ | 429,532 |  |  | $ | 309,310 |
(1) | Accumulated depreciation and amortization includes write-offs due to retirement of fully amortized fixed assets.
The useful lives of depreciable assets are as follows:
| Useful Life in Years
Computer and other equipment | 3-8
Buildings | 30
Furniture and fixtures | 5
Leasehold improvements | Shorter of the lease term or the estimated useful life
Goodwill. Effective in the first quarter of fiscal 2019, with the change in the Company’s reportable segment structure, the Company has determined there are now two reporting units. Goodwill is allocated to the two reporting units using a relative fair value method. Goodwill represents the excess of the aggregate purchase price over the fair value of the net tangible and identifiable intangible assets acquired by the Company. The carrying amount of goodwill at each reporting unit is tested for impairment annually as of October 31, or more frequently if facts and circumstances warrant a review. As a result of changes to the Company's segment reporting, the Company conducted a quantitative impairment test for each of its reporting units in the first quarter of fiscal 2019 and concluded that there was no impairment. The Company performs either a qualitative or quantitative analysis when testing a reporting unit’s goodwill for impairment. A qualitative goodwill impairment test is performed when the fair value of a reporting unit historically has significantly exceeded the carrying value of its net assets and based on current operations is expected to continue to do so. Otherwise, the Company is required to conduct a quantitative impairment test for each reporting unit and estimate the fair value of each reporting unit using a combination of an income approach based on discounted cash flow analysis and a market approach based on market multiples. The discount rate used in the income approach is based on the Company's weighted-average cost of capital and may be adjusted for the relevant risks pertaining to projecting future cash flows. If the fair value of a reporting unit is less than its carrying value, a goodwill impairment charge is recorded for the difference. As of October 31, 2019, the Company performed a qualitative impairment test on each of the reporting units and concluded no goodwill impairments. Intangible Assets. Intangible assets consist of acquired technology, certain contract rights, customer relationships, trademarks and trade names, capitalized software, and in-process research and development. These intangible assets are acquired through business combinations, direct purchases, or internally developed capitalized software. Intangible assets are amortized on a straight-line basis over their estimated useful lives which range from one to ten years, except for in-process research and development (IPR&D) projects not yet completed. IPR&D assets are amortized over their estimated useful lives upon completion or are written off upon abandonment. The Company continually monitors events and changes in circumstances that could indicate carrying amounts of long-lived assets, including property and equipment and intangible assets, may not be recoverable. When such events or changes in circumstances occur, the Company assesses the recoverability of long-lived assets by determining whether the carrying value of such asset group will be recovered through the undiscounted future cash flow. If the undiscounted future cash flow is less than the carrying amount of the asset group, the Company recognizes an impairment loss based on the excess of the carrying amount over the fair value of the asset group. The Company had no material impairment charges for long-lived assets in fiscal 2019 and 2018, and none in fiscal 2017. Restructuring Charges. In the second quarter of fiscal 2019, the Company initiated restructuring plans for involuntary and voluntary employee termination and facility closure actions as part of a business reorganization to better position the Company for future growth by reallocating resources to priority areas, and to a lesser extent, eliminating operational redundancy. The total charges under the 2019 restructuring plans are expected to be $56 million to $65 million and consist primarily of severance, termination, and retirement benefits under the 2019 Voluntary Retirement Program (VRP). The actual total charges depend, in part, on the number of eligible employees accepting offers of the VRP. The 2019 restructuring plans are anticipated to be completed by the second quarter of fiscal 2020. During fiscal 2019, the Company incurred restructuring charges of approximately $47.2 million for involuntary employee termination actions and the VRP. These charges consist primarily of severance, termination, and retirement benefits, of which $24.6 million was paid in fiscal 2019. As of October 31, 2019, $22.6 million remained outstanding and was recorded in accounts payable and accrued liabilities as payroll and related benefits in the consolidated balance sheets. The remaining balance will be paid in fiscal 2020. During fiscal 2018, the Company recorded $12.9 million of restructuring charges for severance and benefits due to involuntary employee termination actions. The restructuring actions were undertaken to position the Company for future growth, reallocate resources to priority areas and, to a lesser extent, eliminate operational redundancy. These charges consisted primarily of severance benefits. As of October 31, 2018, there was an $8.1 million outstanding balance remaining in accounts payable and accrued liabilities in the consolidated balance sheets. The majority of remaining balance was paid in fiscal 2019. During fiscal 2017, the Company recorded $36.6 million of restructuring charges for severance and benefits due to involuntary employee termination actions. The restructuring actions were undertaken to position the Company for future growth, reallocate resources to priority areas, and to a lesser extent, eliminate operational redundancy. These charges consist primarily of severance and retirement benefits. As of October 31, 2017, there was a $17.5 million outstanding balance remaining in accounts payable and accrued liabilities in the consolidated balance sheets, which was paid in fiscal 2018.

Other Comprehensive Income (Loss). Other comprehensive income (loss) (OCI) includes all changes in equity during a period, such as accumulated net translation adjustments, unrealized gain (loss) on certain foreign currency forward contracts that qualify as cash flow hedges, reclassification adjustments related to cash flow hedges and unrealized gain (loss) on investments. See Note 8. Accumulated Other Comprehensive Income (Loss). Revenue Recognition. In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Codification ASC 606 which supersedes the revenue recognition requirements in ASC 605. The new guidance creates a single, principle-based model for revenue recognition that is intended to expand and improve companies' revenue disclosures. For revenue recognition policies under ASC 605, refer to Note 2 - Summary of Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended October 31, 2018. ASC 606 requires a company to recognize revenue when goods are transferred or services are provided to customers in an amount that reflects the consideration to which the company expects to be entitled to in exchange for those goods or services. ASC 606 also requires disclosures enabling users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The FASB has issued several amendments to ASC 606, including amendments that deferred the initially proposed adoption date and clarified accounting for licenses of intellectual property and identifying performance obligations. The Company adopted ASC 606 at the beginning of fiscal 2019 using the modified retrospective transition method. Under this method, periods prior to the adoption date are not adjusted and continue to be reported under the revenue accounting literature in effect during those periods. The Company evaluated contracts that were in effect at the beginning of fiscal 2019 as if they had been accounted for under ASC 606 from the contract inception and summarized the most significant adoption impacts as follows:
• | Revenue for certain ongoing contracts that was previously deferred would have been recognized in the periods prior to adoption under ASC 606. Therefore, upon adoption, the Company recorded the following adjustments to the beginning balances to reflect the amount of revenue that will no longer be recognized in future periods for such contracts: an increase to retained earnings of $265.1 million, a decrease to unbilled receivables of $27.4 million, an increase to contract assets of $126.9 million, and a decrease in deferred revenue of $165.6 million.
• | The Company capitalized $73.8 million of incremental costs for obtaining contracts with customers at the adoption date with a corresponding adjustment to retained earnings and is amortizing these costs over the contract term.
• | The Company recorded an increase in its opening deferred tax liability of $81.4 million, with a corresponding adjustment to retained earnings, to record the tax effect of the above adjustments.
The impacts of adopting ASC 606 on the Company's consolidated financial statements for fiscal 2019 are summarized in the tables below. Balance Sheet Accounts The following table summarizes the effects of adopting ASC 606 on certain account balances of the consolidated balance sheets that were impacted as of October 31, 2019:

Statements of Cash Flows Adoption of ASC 606 had no impact to cash from or used in operating, financing, or investing activities on the consolidated statements of cash flows. Revenue Policy The core principle of ASC 606 is to recognize revenue for the transfer of services or products to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services or products. The principle is achieved through the following five-step approach:
• | Identification of the contract, or contracts, with the customer
• | Identification of the performance obligation in the contract
• | Determination of the transaction price
• | Allocation of the transaction price to the performance obligations in the contract
• | Recognition of revenue when, or as, the Company satisfies a performance obligation
Nature of Products and Services The Company generates revenue from the sale of products that include software licenses and, to a lesser extent, hardware products, maintenance and services. The various types are set forth below. Electronic Design Automation Software license revenue consists of fees associated with the licensing of the Company's software primarily through Technology Subscription License (TSL) contracts. TSLs are time-based licenses for a finite term and generally provide the customer with limited rights to receive, or to exchange certain quantities of licensed software for, unspecified future technology. The majority of the Company's arrangements are TSLs due to the nature of its business and customer requirements. In addition to the licenses, the arrangements also include: post-contract customer support, which includes providing frequent updates and upgrades to maintain the utility of the software due to rapid changes in technology; other intertwined services such as multiple copies of the tools; assisting the Company's customers in applying the Company's technology in the customers' development environment; and rights to remix licenses for other licenses. Payments are generally received in equal or near equal installments over the term of the arrangement. Under ASC 605, these arrangements were qualified to be recognized ratably over the contract terms. Under ASC 606, the Company has concluded that its software licenses in TSL contracts are not distinct from its obligation to provide unspecified software updates to the licensed software throughout the license term. Such updates represent inputs to a single, combined performance obligation, commencing upon the later of the arrangement effective date or transfer of the software license. Remix rights are not an additional promised good or service in the contract, and where unspecified additional software product rights are part of the contract with the customer, such rights are accounted for as part of the single performance obligation that includes the licenses, updates, and technical support because such rights are provided for the same period of time and have the same pattern of transfer to the customer over the duration of the subscription term. IP & System Integration The Company generally licenses IP under nonexclusive license agreements that provide usage rights for specific applications. Additionally, for certain IP license agreements, royalties are collected as customers sell their own products that incorporate the Company’s IP. Under ASC 605, the Company recognized revenue either upfront if certain criteria in ASC 605 were met, or over the contractual period for IP licensing and support arrangements if such arrangements were combined with other TSL arrangements. Under ASC 606, these arrangements generally have two distinct performance obligations that consist of transferring the licensed IP and the support service. Support services consist of a stand-ready obligation to provide technical support and software updates over the support term. Revenue allocated to the IP license is recognized at a point in time upon the later of the delivery date or the beginning of the license period, and revenue allocated to support services is recognized ratably over the support term. Royalties are recognized as revenue is earned, generally when the customer sells its products that incorporate the Company’s IP. Software Integrity Products Software Integrity product arrangements provide customers the right to software licenses, software updates and technical support. Under the term of these arrangements, the customer expects to receive integral updates to the software licenses that protect the customer’s software from potential security vulnerabilities. The licenses and software updates together serve to fulfill the Company’s commitment to the customer, as they represent inputs to a single, combined performance obligation that commences upon the later of the arrangement effective date or transfer of the software license. Software updates are part of the contract with the customer, and such rights are accounted for as part of the single performance obligation that includes the licenses, updates, and technical support because such rights are provided for the same period of time and have the same time-based pattern of transfer to the customer. Hardware The Company generally has two performance obligations in arrangements involving the sale of hardware products. The first performance obligation is to transfer the hardware product, which includes embedded software integral to the functionality of the hardware product. The second performance obligation is to provide maintenance on the hardware and its embedded software, including rights to technical support, hardware repairs and software updates that are all provided over the same term and have the same time-based pattern of transfer to the customer. The portion of the transaction price allocated to the hardware product is generally recognized as revenue at a point in time when the hardware is delivered to the customer. The Company has concluded that control generally transfers upon delivery because the customer has title to the hardware, physical possession of the hardware, and a present obligation to pay for the hardware. The portion of the transaction price allocated to maintenance is recognized as revenue that is ratable over the maintenance term. The adoption of ASC 606 did not change the timing of revenue recognition for hardware products and related services. Professional Services The Company's arrangements often include service elements (other than maintenance and support services). These services include training, design assistance, and consulting. Services performed on a time and materials basis are recognized over time, as the customer simultaneously receives and consumes the benefit provided. Certain arrangements also include the customization or modification of licensed IP. Revenue from these contracts is recognized over time as the services are performed, when the development is specific to the customer’s needs and Synopsys has enforceable rights to payment for performance completed. Performance is generally measured using costs incurred or hours expended to measure progress. The Company has a history of accurately estimating project status and the costs necessary to complete projects. A number of internal and external factors can affect these estimates, including labor rates, utilization and efficiency variances, specification and testing requirement changes, and changes in customer delivery priorities. Payments for services are generally due upon milestones in the contract or upon consumption of the hourly resources. Flexible Spending Accounts Some customers enter into a non-cancelable Flexible Spending Account arrangement (FSA) whereby the customer commits to a fixed dollar amount over a specified period of time that can be used to purchase from a list of Synopsys products or services. These arrangements do not meet the definition of a revenue contract until the customer executes a separate order to identify the required products and services that they are purchasing. The combination of the FSA arrangement and the subsequent order creates enforceable rights and obligations, thus meeting the definition of a revenue contract. Each separate order under the agreement is treated as an individual contract under the new standard and accounted for based on the respective performance obligations included within the FSA arrangements. Disaggregated Revenue The following table shows the percentage of revenue by product groups:
| Year Ended October 31,
| 2019 |  | 2018 |  | 2017
EDA | 59 | % |  | 62 | % |  | 66 | %
IP & System Integration | 31 | % |  | 29 | % |  | 28 | %
Software Integrity Products & Services | 10 | % |  | 9 | % |  | 6 | %
Other | — | % |  | — | % |  | — | %
Total | 100 | % |  | 100 | % |  | 100 | %
Judgments The Company’s contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether services and products are considered distinct performance obligations that should be accounted for separately versus together requires significant judgment. The Company has concluded that (1) its EDA software licenses in TSL contracts are not distinct from its obligation to provide unspecified software updates to the licensed software throughout the license term, because those promises represent inputs to a single, combined performance obligation, and (2) where unspecified additional software product rights are part of the contract with the customer, such rights are accounted for as part of the single performance obligation that includes the licenses, updates, and technical support, because such rights are provided for the same period of time and have the same time-based pattern of transfer to the customer. In reaching this conclusion, the Company considered the nature of the obligation to customers which is to provide an ongoing right to use the most up to date and relevant software. As EDA customers operate in a rapidly changing and competitive environment, satisfying the obligation requires providing critical updates to the existing software products, including ongoing iterative interaction with customers to make the software relevant to customers’ ability to meet the time to go to market with advanced products. Similarly, the Company also concluded that in its Software Integrity business, the licenses and maintenance updates serve together to fulfill the Company’s commitment to the customer as both work together to provide the functionality to the customer and represent a combined performance obligation because the updates are essential to the software’s central utility, which is to identify security vulnerabilities and other threats. Judgment is also required to determine the standalone selling price (SSP) for each distinct performance obligation. For non-software performance obligations (IP, Hardware, and services), SSP is established based on observable prices of products and services sold separately. SSP for license (and related updates and support) in a contract with multiple performance obligations is determined by applying a residual approach whereby all other non-software performance obligations within a contract are first allocated a portion of the transaction price based upon their respective SSP, using observable prices, with any residual amount of the transaction price allocated to the license because the Company does not sell the license separately, and the pricing is highly variable. Contract Balances The timing of revenue recognition may differ from the timing of invoicing to customers, and these timing differences result in receivables (billed or unbilled), contract assets, or contract liabilities (deferred revenue) on the Company’s consolidated balance sheet. The Company records a contract asset when revenue is recognized prior to the right to invoice, or deferred revenue when revenue is recognized subsequent to invoicing. For time-based software agreements, customers are generally invoiced in equal, quarterly amounts, although some customers prefer to be invoiced in single or annual amounts. The Company records an unbilled receivable when revenue is recognized and it has an unconditional right to invoice and receive payment. The contract assets indicated below are presented as prepaid and other current assets in the consolidated balance sheet. The contract assets are transferred to receivables when the rights to invoice and receive payment become unconditional. Contract balances are as follows:
| Balance as of October 31, 2019 |  | Balance as of October 31, 2018
|  |  | as adjusted
| (in thousands)
Contract assets | $ | 210,557 |  |  | $ | 126,897 |
Unbilled receivables | 38,175 |  |  | 36,699 |
Deferred revenue | 1,302,578 |  |  | 1,104,110 |
During fiscal 2019, the Company recognized approximately $1 billion of revenue that was included in the deferred revenue balance at the beginning of the period, as adjusted for the adoption of ASC 606. Contracted but unsatisfied or partially unsatisfied performance obligations were approximately $4.4 billion as of October 31, 2019, which includes $494.3 million in non-cancellable FSA commitments from customers where actual product selection and quantities of specific products or services are to be determined by customers at a later date. The Company has elected to exclude future sales-based royalty payments from the remaining performance obligations. The contracted but unsatisfied or partially unsatisfied performance obligations, excluding non-cancellable FSA, expected to be recognized over the next 12 months is approximately 56%, with the remainder recognized thereafter. During fiscal 2019, the Company recognized $80.0 million from performance obligations satisfied from sales based royalties earned during the periods. Costs of Obtaining a Contract with Customer The incremental costs of obtaining a contract with a customer, which consist primarily of direct sales commissions earned upon execution of the contract, are required to be capitalized under ASC 340-40 and amortized over the estimated period of which the benefit is expected to be received. As direct sales commissions paid for renewals are commensurate with the amounts paid for initial contracts, the deferred incremental costs will be recognized over the contract term. Total capitalized direct commission costs as of October 31, 2019 were $86.4 million and are included in other assets in the Company’s consolidated balance sheet. Amortization of these assets was $62.8 million during fiscal 2019 and is included in sales and marketing expense in the Company’s consolidated statements of operations. Warranties and Indemnities. The Company generally warrants its products to be free from defects in media and to substantially conform to material specifications for a period of 90 days for software products and for up to six months for hardware systems. In certain cases, the Company also provides its customers with limited indemnification with respect to claims that their use of the Company’s software products infringes on United States patents, copyrights, trademarks or trade secrets. The Company is unable to estimate the potential impact of these commitments on the future results of operations. To date, the Company has not been required to pay any material warranty claims. Net Income Per Share. The Company computes basic income per share by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted net income per share reflects the dilution from potential common shares outstanding such as stock options and unvested restricted stock units and awards during the period using the treasury stock method. The table below reconciles the weighted average common shares used to calculate basic net income per share with the weighted average common shares used to calculate diluted net income per share:

Diluted | $ | 3.45 |  |  | $ | 2.82 |  |  | $ | 0.88 |
Anti-dilutive employee stock-based awards excluded(1) | 171 |  |  | 850 |  |  | 345 |
(1) These stock options and unvested restricted stock units were anti-dilutive for the respective periods and are excluded in calculating diluted net income per share. While such awards were anti-dilutive for the respective periods, they could be dilutive in the future.
