Summary of Significant Accounting Policies	Jan. 02, 2021
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Cadence and its subsidiaries after elimination of intercompany accounts and transactions. All consolidated subsidiaries are wholly owned by Cadence. Cadence’s fiscal years are 52- or 53-week periods ending on the Saturday closest to December 31. Fiscal 2020 was a 53- week year, while 2019 and 2018 were each 52-week fiscal years. Use of Estimates Preparation of the consolidated financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Recently Adopted Accounting Standards Credit Losses In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” which required the establishment of an allowance for estimated credit losses on financial assets, including trade and other receivables, at each reporting date. Cadence adopted the new standard on December 29, 2019, the first day of fiscal 2020, and recorded a cumulative-effect adjustment to decrease retained earnings in the amount of $2.0 million for expected credit losses on financial assets at the adoption date. The adoption of this standard required Cadence to modify its existing process for establishing credit losses on trade receivables, including receivables derived from leasing arrangements for its emulation and prototyping hardware. Goodwill Impairment In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” that eliminates “Step 2” from the goodwill impairment test. Cadence adopted the new standard on December 29, 2019, the first day of fiscal 2020. The new standard did not have an impact on Cadence’s consolidated financial statements and related disclosures. Fair Value Measurements In August 2018, the FASB issued ASU 2018-13, “Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement,” which modifies the disclosure requirements on fair value measurements. Cadence adopted the new standard on December 29, 2019, the first day of fiscal 2020. The new standard did not have a material impact on Cadence’s consolidated financial statements and related disclosures. Implementation Costs Incurred in a Cloud Computing Arrangement In August 2018, the FASB issued ASU 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” which clarifies the accounting for implementation costs in cloud computing arrangements. The new standard aligns the treatment of implementation costs incurred by customers in cloud computing arrangements that are service contracts with the treatment of similar costs incurred to develop or obtain internal-use software. Under the new standard, implementation costs are deferred and presented in the same financial statement caption on the condensed consolidated balance sheet as a prepayment of related arrangement fees. The deferred costs are recognized over the term of the arrangement in the same financial statement caption in the condensed consolidated income statement as the related fees of the arrangement. Cadence adopted the new standard on December 29, 2019, the first day of fiscal 2020. The new standard did not have a material impact on Cadence’s condensed consolidated financial statements and related disclosures. New Accounting Standards Not Yet Adopted Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes,” which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. The new standard is effective for fiscal years beginning after December 15, 2020. Most amendments within the standard are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. Cadence is currently evaluating the impacts of the provisions of this standard on its financial condition, results of operations and cash flows. Foreign Operations Cadence transacts business in various foreign currencies. The United States dollar is the functional currency of Cadence’s consolidated entities operating in the United States and certain of its consolidated subsidiaries operating outside the United States. The functional currency for Cadence’s other consolidated entities operating outside of the United States is generally the country’s local currency. Cadence translates the financial statements of consolidated entities whose functional currency is not the United States dollar into United States dollars. Cadence translates assets and liabilities at the exchange rate in effect as of the financial statement date and translates income statement accounts using an average exchange rate for the period. Cadence includes adjustments from translating assets and liabilities into United States dollars, and the effect of exchange rate changes on intercompany transactions of a long-term investment nature in stockholders’ equity as a component of accumulated other comprehensive income. Cadence reports gains and losses from foreign exchange rate changes related to intercompany receivables and payables that are not of a long-term investment nature, as well as gains and losses from foreign currency transactions of a monetary nature in other income, net, in the consolidated income statements. Concentrations of Credit Risk Financial instruments, including derivative financial instruments, that may potentially subject Cadence to concentrations of credit risk, consist principally of cash and cash equivalents, accounts receivable, investments and forward contracts. Credit exposure related to Cadence’s foreign currency forward contracts is limited to the realized and unrealized gains on these contracts. Cash and Cash Equivalents Cadence considers all highly liquid investments with original maturities of three months or less on the date of purchase to be cash equivalents. Book overdraft balances are recorded in accounts payable and accrued liabilities in the consolidated balance sheets and are reported as a component of cash flows from financing activities in the consolidated statement of cash flows. Receivables Cadence’s receivables, net includes invoiced accounts receivable and the current portion of unbilled receivables. Unbilled receivables represent amounts Cadence has recorded as revenue for which payments from a customer are due over time and Cadence has an unconditional right to the payment. Cadence’s accounts receivable and unbilled receivables were initially recorded at the transaction value. Cadence’s long-term receivables balance includes receivable balances to be invoiced more than one year after each balance sheet date. Allowances for Doubtful Accounts Cadence assesses its ability to collect outstanding receivables and provides customer-specific allowances, allowances for credit losses and general allowances for the portion of its receivables that are estimated to be uncollectible. The allowances are based on the current creditworthiness of its customers, historical experience, expected credit losses, changes in customer demand and the overall economic climate in the industries that Cadence serves. Provisions for these allowances are recorded in general and administrative expense in Cadence’s consolidated income statements. Inventories Inventories are computed at standard costs which approximate actual costs and are valued at the lower of cost or net realizable value based on the first-in, first-out method. Cadence’s inventories include high technology parts and components for complex emulation and prototyping hardware systems. These parts and components are specialized in nature and may be subject to rapid technological obsolescence. While Cadence has programs to minimize the required inventories on hand and considers technological obsolescence when estimating required reserves to reduce recorded amounts to market values, it is reasonably possible that such estimates could change in the near term. Cadence’s policy is to reserve for inventory in excess of 12-month demand or for other known obsolescence or realization issues. Property, Plant and Equipment Property, plant and equipment is stated at historical cost. Depreciation and amortization are generally provided over the estimated useful lives, using the straight-line method, as follows: Computer equipment and related software 2-7 years Buildings 25-32 years Leasehold improvements Shorter of the lease term or the estimated useful life Building improvements and land improvements Up to 32 years Furniture and fixtures 3-5 years Equipment 3-5 years Cadence capitalizes certain costs of software developed for internal use. Capitalization of software developed for internal use begins at the application development phase of the project. Amortization begins when the computer software is substantially complete and ready for its intended use. Amortization is recorded on a straight-line basis over the estimated useful life. Cadence capitalized costs of software developed for internal use of $0.9 million, $2.4 million, and $3.6 million during fiscal 2020, 2019 and 2018, respectively. Cadence recorded depreciation and amortization expense of $67.6 million, $63.3 million and $60.4 million during fiscal 2020, 2019 and 2018, respectively, for property, plant and equipment. Software Development Costs Software development costs are capitalized beginning when a product’s technological feasibility has been established by completion of a working model of the product and amortization begins when a product is available for general release to customers. The period between the achievement of technological feasibility and the general release of Cadence’s products has typically been of short duration. Costs incurred during fiscal 2020, 2019 and 2018 were not material. Deferred Sales Commissions Cadence records an asset for the incremental costs of obtaining a contract with a customer, including direct sales commissions that are earned upon execution of the contract. Cadence uses the portfolio method to recognize the amortization expense related to these capitalized costs related to initial contracts and renewals and such expense is recognized over a period associated with the revenue of the related portfolio, which is generally two to three years for Cadence’s software arrangements and upon delivery for its hardware and IP arrangements. Incremental costs related to initial contracts and renewals are amortized over the period of the arrangement in each case because Cadence pays the same commission rate for both new contracts and renewals. Deferred sales commissions are tested for impairment on an ongoing basis when events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment is recognized to the extent that the amount of deferred sales commission exceeds the remaining expected gross margin (remaining revenue less remaining direct costs) on the goods and services to which the deferred sales commission relates. Total capitalized costs were $36.7 million and $31.6 million as of January 2, 2021, and December 28, 2019, respectively, and are included in other assets in Cadence’s consolidated balance sheet. Amortization of these assets was $34.6 million, $29.4 million and $26.5 million during fiscal 2020, 2019 and 2018, respectively, and is included in sales and marketing expense in Cadence’s consolidated income statement. Goodwill Cadence conducts a goodwill impairment analysis annually and as necessary if changes in facts and circumstances indicate that the fair value of Cadence’s single reporting unit may be less than its carrying amount. To assess for impairment, Cadence compares the estimated fair value of its single reporting unit to the carrying value of the reporting unit’s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further analysis is required. If the fair value of the reporting unit is less than the carrying value of its net assets, Cadence would be required to record an impairment charge. Long-Lived Assets, Including Acquired Intangibles Cadence’s long-lived assets consist of property, plant and equipment, and acquired intangibles. Acquired intangibles with definite lives are amortized on a straight-line basis over the estimated economic life of the underlying products and technologies, which range from three Cadence reviews its long-lived assets, including acquired intangibles, for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset or asset group may not be recoverable. Recoverability of an asset or asset group is measured by comparison of its carrying amount to the expected future undiscounted cash flows that the asset or asset group is expected to generate. If it is determined that the carrying amount of an asset group is not recoverable, an impairment loss is recorded in the amount by which the carrying amount of the asset or asset group exceeds its fair value. Leases Cadence adopted ASU 2016-02, “Leases (Topic 842)” (“Topic 842”) on the first day of fiscal 2019 and the adoption of the standard did not have a material impact on Cadence’s results from operations or cash flows. Lessee Considerations Cadence has operating leases primarily consisting of facilities with remaining lease terms of approximately one year to fifteen years. Cadence has options to terminate many of its leases early. The lease term represents the period up to the early termination date unless it is reasonably certain that Cadence will not exercise the early termination option. For certain leases, Cadence has options to extend the lease term for additional periods ranging from one year to ten years. These renewal options are not considered in the remaining lease term unless it is reasonably certain that Cadence will exercise such options. At inception of a contract, Cadence determines an arrangement contains a lease if the arrangement conveys the right to use an identified asset and Cadence obtains substantially all of the economic benefits from the asset and has the ability to direct the use of the asset. Leases with an initial term of twelve months or less are not recorded on the balance sheet. For lease agreements entered into or reassessed after the adoption of Topic 842, Cadence combines the lease and non-lease components in determining the lease liabilities and right-of-use (“ROU”) assets. Non-lease components primarily include common-area maintenance and other management fees. Operating lease expense is generally recognized evenly over the term of the lease. Payments under Cadence's lease agreements are primarily fixed; however, certain agreements contain rental payments that are adjusted periodically based on changes in consumer price and other indices. Changes to payments resulting from changes in indices are expensed as incurred and not included in the measurement of lease liabilities and ROU assets. Cadence’s lease agreements do not provide an implicit borrowing rate, therefore an internal incremental borrowing rate is determined based on information available at lease commencement date for purposes of determining the present value of lease payments. The incremental borrowing rate represents a comparable rate to borrow on a collateralized basis over a similar term and in the economic environment where the leased asset is located. Cadence used the incremental borrowing rate on the effective date of adoption of Topic 842 for all leases that commenced prior to that date. Lessor Considerations Although most of Cadence’s revenue from its hardware business comes from sales of hardware, Cadence also leases its hardware products to some customers. Cadence determines the existence of a lease when the customer controls the use of the identified hardware for a period of time defined in the lease agreement. Cadence’s leases range in duration up to three years with payments generally collected in equal quarterly installments. Cadence’s leases do not include termination rights or variable pricing and typically do not include purchase rights at the end of the lease. Short-term leases are usually less than two years and are classified as operating leases with revenue recognized and depreciation expensed on a straight-line basis over the term of the lease. Long-term leases are typically for three years and are classified as sales-type leases with revenue and cost of sales recognized upon delivery. Cadence’s operating leases and sales-type leases contain both lease and non-lease components. Because the pattern of revenue recognition is the same for both the lease and non-lease components in Cadence’s operating leases, Cadence has elected the practical expedient to not separate lease and related non-lease components and accounts for both components under Topic 842. Cadence allocates value to the lease and non-lease components in its sales-type leases using standalone selling prices (“SSPs”) similar to those used under ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” the current accounting standard governing revenue recognition. When Cadence leases its hardware in the same arrangement as software or IP, Cadence allocates value to each performance obligation using SSPs. Investments in Equity Securities Cadence’s investments in marketable equity securities are carried at fair value as a component of prepaid expenses and other in the consolidated balance sheets. Cadence records realized and unrealized holding gains or losses as part of other income, net in the consolidated income statements. Cadence’s non-marketable investments include its investments in privately held companies. These investments are initially recorded at cost and are included in other assets in the consolidated balance sheets. Cadence accounts for these investments using the measurement alternative when the fair value of the investment is not readily determinable and Cadence does not have the ability to exercise significant influence or the equity method of accounting when it is determined that Cadence has the ability to exercise significant influence. For investments accounted for using the equity method of accounting, Cadence records its proportionate share of the investee’s income or loss, net of the effects of any basis differences, to other income, net on a one-quarter lag in Cadence’s consolidated income statements. Cadence reviews its non-marketable investments on a regular basis to determine whether its investments in these companies are impaired. Cadence considers investee financial performance and other information received from the investee companies, as well as any other available estimates of the fair value of the investee companies in its review. If Cadence determines the carrying value of an investment exceeds its fair value, the book value of the investment is adjusted to its fair value. Cadence records investment write-downs in other income, net, in the consolidated income statements. Derivative Financial Instruments Cadence enters into foreign currency forward exchange contracts with financial institutions to protect against currency exchange risks associated with existing assets and liabilities. A foreign currency forward exchange contract acts as a hedge by increasing in value when underlying assets decrease in value or underlying liabilities increase in value due to changes in foreign exchange rates. Conversely, a foreign currency forward exchange contract decreases in value when underlying assets increase in value or underlying liabilities decrease in value due to changes in foreign exchange rates. The forward contracts are not designated as accounting hedges and, therefore, the unrealized gains and losses are recognized in other income, net, in advance of the actual foreign currency cash flows. The fair value of these forward contracts is recorded in accrued liabilities or in other current assets. These forward contracts generally have maturities of 90 days or less. Nonqualified Deferred Compensation Trust Executive officers, senior management and members of Cadence’s Board of Directors may elect to defer compensation payable to them under Cadence’s Nonqualified Deferred Compensation Plan (“NQDC”). Deferred compensation payments are held in investment accounts and the values of the accounts are adjusted each quarter based on the fair value of the investments held in the NQDC. The selected investments held in the NQDC accounts are carried at fair value, with the unrealized gains and losses recognized in the consolidated income statements as other income, net. These securities are classified in other assets in the consolidated balance sheets because they are not available for Cadence’s use in its operations. Cadence’s obligation with respect to the NQDC trust is recorded in other long-term liabilities on the consolidated balance sheets. Increases and decreases in the NQDC trust liability are recorded as compensation expense in the consolidated income statements. Treasury Stock Cadence generally issues shares related to its stock-based compensation plans from shares held in treasury. When treasury stock is reissued at an amount higher than its cost, the difference is recorded as a component of capital in excess of par in the consolidated statements of stockholders’ equity. When treasury stock is reissued at an amount lower than its cost, the difference is recorded as a component of capital in excess of par to the extent that gains exist to offset the losses. If there are no accumulated treasury stock gains in capital in excess of par, the losses upon reissuance of treasury stock are recorded as a component of retained earnings in the consolidated statements of stockholders’ equity. There were no losses recorded as a component of retained earnings by Cadence on the reissuance of treasury stock during fiscal 2020, 2019 or 2018. Revenue Recognition Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration to which Cadence expects to be entitled in exchange for promised goods or services. Cadence’s performance obligations are satisfied either over time or at a point in time. In any fiscal year, between 85% and 90% of revenue is characterized as recurring revenue. Revenue characterized as recurring includes revenue recognized over time from Cadence’s software arrangements, services, royalties, maintenance on IP licenses and hardware, and operating leases of hardware and revenue recognized at varying points in time over the term of our IP Access Agreements (“IPAA”). The remainder of Cadence’s revenue is characterized as up-front revenue. Up-front revenue is primarily generated by sales of emulation and prototyping hardware and individual IP licenses. Product and maintenance revenue includes Cadence’s licenses of software and IP, sales of emulation hardware and the related maintenance on these licenses and sales. Service revenue includes revenue received for performing engineering services (which are generally not related to the functionality of other licensed products), customized IP on a fixed fee basis, and sales from cloud-based solutions that provide customers with software and services over a period of time. Cadence enters into contracts that can include various combinations of licenses, products and services, some of which are distinct and are accounted for as separate performance obligations. For contracts with multiple performance obligations, Cadence allocates the transaction price of the contract to each performance obligation, generally on a relative basis using its SSP. We generate revenue from contracts with customers and apply judgement in identifying and evaluating any terms and conditions in contracts which may impact revenue recognition. Revenue is recognized net of any taxes collected from customers that are subsequently remitted to governmental authorities. Software Revenue Recognition Cadence’s time-based license arrangements grant customers the right to access and use all of the licensed products at the outset of an arrangement and updates are generally made available throughout the entire term of the arrangement, which is generally two to three years. Cadence’s updates provide continued access to evolving technology as customers’ designs migrate to more advanced nodes and as its customers’ technological requirements evolve. In addition, certain time-based license arrangements include remix rights and unspecified additional products that become commercially available during the term of the agreement. Payments are generally received in equal or near equal installments over the term of the agreement. Multiple software licenses, related updates, and technical support in these time-based arrangements constitute a single, combined performance obligation and revenue is recognized over the term of the license, commencing upon the later of the effective date of the arrangement 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 time-based pattern of transfer to the customer. Hardware Revenue Recognition Cadence generally has two performance obligations in arrangements involving the sale or lease of hardware products. The first performance obligation is to transfer the hardware product (which includes software integral to the functionality of the hardware product). The second performance obligation is to provide maintenance on hardware and its embedded software, which includes 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 transaction price allocated to the hardware product is generally recognized as revenue at the time of delivery because the customer obtains control of the product at that point in time. Cadence has concluded that control generally transfers at that point in time because the customer has title to the hardware, physical possession, and a present obligation to pay for the hardware. The transaction price allocated to maintenance is recognized as revenue ratably over the maintenance term. Payments for hardware contracts are generally received upon delivery of the hardware product. Shipping and handling costs are considered fulfillment costs and are included in cost of product and maintenance in Cadence’s consolidated income statements. IP Revenue Recognition Cadence generally licenses IP under nonexclusive license agreements that provide usage rights for specific designs. In addition, for certain of Cadence’s IP license agreements, royalties are collected as customers ship their own products that incorporate Cadence IP. These arrangements generally have two performance obligations—transferring the licensed IP and associated maintenance, which includes rights to technical support, and software updates that are all provided over the maintenance term and have a time-based pattern of transfer to the customer. Some customers enter into a non-cancellable IPAA 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 IP products or services. These arrangements do not meet the definition of a revenue contract until the customer executes a separate selection form to identify the products and services that they are purchasing. Each separate selection form under the IPAA is treated as an individual contract and accounted for based on the respective performance obligations. Revenue allocated to the IP license is recognized at a point in time upon the later of the delivery of the IP or the beginning of the license period and revenue allocated to the maintenance is recognized over the maintenance term. Royalties are recognized as revenue in the quarter in which the applicable Cadence customer ships its products that incorporate Cadence IP. Payments for IP contracts are generally received upon delivery of the IP. Cadence customizes certain IP and revenue related to this customization is recognized as services revenue as described below. Services Revenue Recognition Revenue from service contracts is recognized over time, generally using costs incurred or hours expended to measure progress. Cadence 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 and specification and testing requirement changes. Payments for services are generally due upon milestones in the contract or upon consumption of the hourly resources. Stock-Based Compensation Cadence recognizes the cost of awards of equity instruments granted to employees in exchange for their services as stock-based compensation expense. Stock-based compensation expense is measured at the grant date based on the value of the award and is recognized as expense over the requisite service period, which is typically the vesting period. Cadence recognizes stock-based compensation expense on the straight-line method for awards that only contain a service condition and on the graded-vesting method for awards that contain both a service and performance condition. Cadence recognizes the impact of forfeitures on stock-based compensation expense as they occur. The fair value of stock options and purchase rights issued under Cadence’s Employee Stock Purchase Plan (“ESPP”) are calculated using the Black-Scholes option pricing model. The computation of the expected volatility assumption used for new awards is based on implied volatility when the remaining maturities of the underlying traded options are at least one year. When the remaining maturities of the underlying traded options are less than one year, expected volatility is based on a weighting of historical and implied volatilities. When determining the expected term, Cadence reviews historical employee exercise behavior from options having similar vesting periods. The risk-free interest rate for the period within the expected term of the option is based on the yield of United States Treasury notes for the comparable term in effect at the time of grant. The expected dividend yield used in the calculation is zero because Cadence has not historically paid and currently does not expect to pay dividends in the foreseeable future. Advertising Cadence expenses the costs of advertising as incurred. Total advertising expense, including marketing programs and events, was $7.1 million, $8.4 million and $7.6 million during fiscal 2020, 2019 and 2018, respectively, and is included in marketing and sales in the consolidated income statements. Restructuring Charges Cadence records personnel-related restructuring charges with termination benefits when the costs are both probable and estimable. Cadence records personnel-related restructuring charges with non-customary termination benefits when the plan has been communicated to the affected employees. Cadence records facilities-related restructuring charges in the period in which the affected facilities are vacated. In connection with facilities-related restructuring plans, Cadence has made a number of estimates and assumptions related to losses on excess facilities that have been vacated or consolidated, particularly the timing of subleases and sublease terms. Closure and space reduction costs included in the restructuring charges include payments required under leases less any applicable estimated sublease income after the facilities are abandoned, lease buyout costs and certain contractual costs to maintain facilities during the period after abandonme

Debt Disclosure [Abstract]
DEBT	DEBT Cadence’s outstanding debt as of January 2, 2021 and December 28, 2019 was as follows: January 2, 2021 December 28, 2019 (In thousands) Principal Unamortized Discount Carrying Value Principal Unamortized Discount Carrying Value Revolving Credit Facility $ — $ — $ — $ — $ — $ — 2024 Notes 350,000 (3,207) 346,793 350,000 (3,981) 346,019 Total outstanding debt $ 350,000 $ (3,207) $ 346,793 $ 350,000 $ (3,981) $ 346,019 Revolving Credit Facility In January 2017, Cadence entered into a five-year senior unsecured revolving credit facility with a group of lenders led by JPMorgan Chase Bank, N.A., as administrative agent. The credit facility provides for borrowings up to $350.0 million, with the right to request increased capacity up to an additional $250.0 million upon the receipt of lender commitments, for total maximum borrowings of $600.0 million. The credit facility expires on January 28, 2022 and has no subsidiary guarantors. Any outstanding loans drawn under the credit facility are due at maturity on January 28, 2022. Outstanding borrowings may be paid at any time prior to maturity. Interest accrues on borrowings under the credit facility at either LIBOR plus a margin between 1.250% and 1.875% per annum or at the base rate plus a margin between 0.25% and 0.875% per annum. Interest is payable quarterly. A commitment fee ranging from 0.15% to 0.30% is assessed on the daily average undrawn portion of revolving commitments. The credit facility contains customary negative covenants that, among other things, restrict Cadence’s ability to incur additional indebtedness, grant liens, make certain investments (including acquisitions), dispose of certain assets and make certain payments, including share repurchases and dividends. In addition, the credit facility contains financial covenants that require Cadence to maintain a funded debt to EBITDA ratio not greater than 3.00 to 1, with a step up to 3.50 to 1 for one year following an acquisition by Cadence of at least $250.0 million that results in a pro forma leverage ratio between 2.75 to 1 and 3.25 to 1. As of January 2, 2021 and December 28, 2019, Cadence was in compliance with all financial covenants associated with the revolving credit facility. 2024 Notes In October 2014, Cadence issued $350.0 million aggregate principal amount of 4.375% Senior Notes due October 15, 2024 (the “2024 Notes”). Cadence received net proceeds of $342.4 million from the issuance of the 2024 Notes, net of a discount of $1.4 million and issuance costs of $6.2 million. Both the discount and issuance costs are being amortized to interest expense over the term of the 2024 Notes using the effective interest method. Interest is payable in cash semi-annually in April and October. The 2024 Notes are unsecured and rank equal in right of payment to all of Cadence’s existing and future senior indebtedness. The fair value of the 2024 Notes was approximately $393.2 million as of January 2, 2021. Cadence may redeem the 2024 Notes, in whole or in part, at a redemption price equal to the greater of (a) 100% of the principal amount of the notes to be redeemed and (b) the sum of the present values of the remaining scheduled payments of principal and interest, plus any accrued and unpaid interest, as more particularly described in the indenture governing the 2024 Notes. The indenture governing the 2024 Notes includes customary representations, warranties and restrictive covenants, including, but not limited to, restrictions on Cadence’s ability to grant liens on assets, enter into sale and lease-back transactions, or merge, consolidate or sell assets, and also includes customary events of default.

Revenue

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE Cadence groups its products into five categories related to major design activities. The following table shows the percentage of product and related maintenance revenue contributed by each of Cadence’s five product categories and services for fiscal 2020 and 2019: 2020 2019 2018 Custom IC Design and Simulation 25 % 25 % 26 % Digital IC Design and Signoff 29 % 30 % 29 % Functional Verification, including Emulation and Prototyping Hardware* 22 % 23 % 24 % IP 14 % 13 % 12 % System Design and Analysis 10 % 9 % 9 % Total 100 % 100 % 100 % _____________ * Includes immaterial amount of revenue accounted for under leasing arrangements. Revenue by product category fluctuates from period to period based on demand for products and services, and Cadence’s available resources to deliver them. Certain of Cadence’s licensing arrangements allow customers the ability to remix among software products. Cadence also has arrangements with customers that include a combination of products, with the actual product selection and number of licensed users to be determined at a later date. For these arrangements, Cadence estimates the allocation of the revenue to product categories based upon the expected usage of products. Significant Judgments Cadence’s contracts with customers often include promises to transfer to a customer multiple software and/or IP licenses and services, including professional services, technical support services, and rights to unspecified updates. Determining whether licenses and services are distinct performance obligations that should be accounted for separately, or not distinct and thus accounted for together, requires significant judgment. In some arrangements, such as most of Cadence’s IP license arrangements, Cadence has concluded that the licenses and associated services are distinct from each other. In others, like Cadence’s time-based software arrangements, the licenses and certain services are not distinct from each other. Cadence’s time-based software arrangements include multiple software licenses and updates to the licensed software products, as well as technical support, and Cadence has concluded that these promised goods and services are a single, combined performance obligation. The accounting for contracts with multiple performance obligations requires the contract’s transaction price to be allocated to each distinct performance obligation based on relative SSP. Judgment is required to determine SSP for each distinct performance obligation because Cadence rarely licenses or sells products on a standalone basis. In instances where the SSP is not directly observable because Cadence does not sell the license, product or service separately, Cadence determines the SSP using information that maximizes the use of observable inputs and may include market conditions. Cadence typically has more than one SSP for individual performance obligations due to the stratification of those items by classes of customers and circumstances. In these instances, Cadence may use information such as the size of the customer and geographic region of the customer in determining the SSP. Revenue is recognized over time for Cadence’s combined performance obligations that include software licenses, updates, technical support and maintenance that are separate performance obligations with the same term. For Cadence’s professional services, revenue is recognized over time, generally using costs incurred or hours expended to measure progress. Judgment is required in 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 and specification and testing requirement changes. For Cadence’s other performance obligations recognized over time, revenue is generally recognized using a time-based measure of progress reflecting generally consistent efforts to satisfy those performance obligations throughout the arrangement term. If a group of agreements are so closely related that they are, in effect, part of a single arrangement, such agreements are deemed to be one arrangement for revenue recognition purposes. Cadence exercises significant judgment to evaluate the relevant facts and circumstances in determining whether the separate agreements should be accounted for separately or as, in substance, a single arrangement. Cadence’s judgments about whether a group of contracts comprise a single arrangement can affect the allocation of consideration to the distinct performance obligations, which could have an effect on results of operations for the periods involved. Cadence is required to estimate the total consideration expected to be received from contracts with customers. In limited circumstances, the consideration expected to be received is variable based on the specific terms of the contract or based on Cadence’s expectations of the term of the contract. Generally, Cadence has not experienced significant returns or refunds to customers. These estimates require significant judgment and the change in these estimates could have an effect on its results of operations during the periods involved. Contract Balances The timing of revenue recognition may differ from the timing of invoicing to customers, and these timing differences result in receivables, contract assets, or contract liabilities (deferred revenue) on Cadence’s consolidated balance sheets. For certain software, hardware and IP agreements with payment plans, Cadence records an unbilled receivable related to revenue recognized upon transfer of control because it has an unconditional right to invoice and receive payment in the future related to those transferred products or services. Cadence records a contract asset when revenue is recognized prior to invoicing and Cadence does not have the unconditional right to invoice or retains performance risk with respect to that performance obligation. Cadence records deferred revenue when revenue is recognized subsequent to invoicing. For Cadence’s 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 contract assets indicated below are presented as prepaid expenses and other in the consolidated balance sheet and primarily relate to Cadence’s rights to consideration for work completed but not billed as of the balance sheet date on services and customized IP contracts. The contract assets are transferred to receivables when the rights become unconditional, usually upon completion of a milestone. Cadence’s contract balances as of January 2, 2021 and December 28, 2019 were as follows: As of January 2, December 28, (In thousands) Contract assets $ 9,709 $ 10,209 Deferred revenue 553,921 428,883 Cadence recognized revenue of $345.9 million, $311.8 million and $284.3 million during fiscal 2020, 2019 and 2018, respectively, that was included in the deferred revenue balance at the beginning of each fiscal year. All other activity in deferred revenue is due to the timing of invoices in relation to the timing of revenue as described above. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 60 days. In instances where the timing of revenue recognition differs from the timing of invoicing, Cadence has determined that its contracts generally do not include a significant financing component. The primary purpose of invoicing terms is to provide customers with simplified and predictable ways of purchasing Cadence’s products and services, and not to facilitate financing arrangements. Remaining Performance Obligations Revenue allocated to remaining performance obligations represents the transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied, which includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods. Cadence has elected to exclude the potential future royalty receipts from the remaining performance obligations. Contracted but unsatisfied performance obligations were approximately $3.9 billion as of January 2, 2021, which included $133.6 million of non-cancellable IPAA commitments from customers where actual product selection and quantities of specific products or services are to be determined by customers at a later date. Contracted but unsatisfied performance obligations were approximately $3.6 billion as of December 28, 2019, which included $205.7 million of non-cancellable IPAA commitments from customers. As of January 2, 2021, Cadence expected to recognize approximately 55% of the contracted but unsatisfied performance obligations, excluding non-cancellable IPAA commitments, as revenue over the next 12 months and the remainder thereafter. Cadence recognized revenue of $51.2 million, $40.4 million and $34.3 million during fiscal 2020, 2019 and 2018, respectively, from performance obligations satisfied in previous periods. These amounts represent royalties earned during the period and exclude contracts with nonrefundable prepaid royalties. Nonrefundable prepaid royalties are recognized upon delivery of the IP because Cadence’s right to the consideration is not contingent upon customers’ future shipments.

INCOME TAXES	INCOME TAXES Cadence’s income before provision (benefit) for income taxes included income from the United States and from foreign subsidiaries for fiscal 2020, 2019 and 2018, was as follows: 2020 2019 2018 (In thousands) United States $ 256,032 $ 139,306 $ 58,963 Foreign subsidiaries 376,716 339,662 317,427 Total income before provision (benefit) for income taxes $ 632,748 $ 478,968 $ 376,390 Cadence’s provision (benefit) for income taxes was comprised of the following items for fiscal 2020, 2019 and 2018: 2020 2019 2018 (In thousands) Current: Federal $ 15,083 $ 15,282 $ 902 State and local 6,401 2,716 (1,270) Foreign 46,737 48,729 42,657 Total current 68,221 66,727 42,289 Deferred: Federal (11,155) (9,001) (10,324) State and local (24,186) 6,593 886 Foreign 9,224 (574,330) (2,238) Total deferred (26,117) (576,738) (11,676) Total provision (benefit) for income taxes $ 42,104 $ (510,011) $ 30,613 During the third quarter of fiscal 2020, the State of California enacted legislation that, for a three-year period beginning in fiscal 2020, will limit Cadence’s utilization of California research and development tax credits to $5 million annually and will suspend the use of California net operating loss deductions. Cadence accounted for the effects of the California tax law change in the period of enactment. Cadence recognized a tax benefit of approximately $22.2 million due to a partial release of the valuation allowance on our California research and development tax credit deferred tax assets as a result of certain tax elections made in Cadence’s 2019 California tax return. During the fourth quarter of fiscal 2019, Cadence completed intercompany transfers of certain intangible property rights to its Irish subsidiary, which resulted in the establishment of a deferred tax asset and the recognition of an income tax benefit of $575.6 million. Cadence expected to realize the Irish deferred tax asset in future years and did not provide for a valuation allowance. Cadence considered all available positive and negative evidence, including its past operating results, forecasted earnings, future taxable income, and any prudent and feasible tax planning strategies in making this determination. The provision for income taxes differs from the amount estimated by applying the United States statutory federal income tax rates of 21% to income before provision (benefit) for income taxes for fiscal 2020, 2019, and 2018 as follows: 2020 2019 2018 (In thousands) Provision computed at federal statutory income tax rate $ 132,877 $ 100,583 $ 79,042 State and local income tax, net of federal tax effect 20,936 23,221 15,540 Intercompany transfers of intangible property rights — (575,618) — Foreign income tax rate differential (32,589) (37,786) (37,031) Deemed repatriation transition tax — — (1,409) U.S. tax on foreign entities 43,615 57,225 28,846 Stock-based compensation (51,226) (29,785) (13,539) Change in deferred tax asset valuation allowance (9,101) 16,796 13,234 Tax credits (89,684) (87,793) (72,815) Non-deductible research and development expense 5,163 4,363 4,700 Tax effects of intra-entity transfer of assets 392 895 79 Withholding taxes 17,189 15,865 11,535 Tax settlements, foreign 1,193 458 — Increase (decrease) in unrecognized tax benefits 159 (1,303) (1,545) Other 3,180 2,868 3,976 Provision (benefit) for income taxes $ 42,104 $ (510,011) $ 30,613 Effective tax rate 7 % (106) % 8 % The components of deferred tax assets and liabilities consisted of the following as of January 2, 2021 and December 28, 2019: As of January 2, December 28, (In thousands) Deferred tax assets: Tax credit carryforwards $ 197,436 $ 206,008 Reserves and accruals 60,272 47,562 Intangible assets 578,267 583,323 Capitalized research and development expense for income tax purposes 39,427 18,477 Operating loss carryforwards 5,935 6,201 Deferred income 21,170 16,704 Capital loss carryforwards 16,944 17,320 Stock-based compensation costs 14,656 15,097 Depreciation and amortization 4,402 8,721 Investments 2,521 2,459 Lease liability 31,278 25,016 Total deferred tax assets 972,308 946,888 Valuation allowance (116,419) (125,520) Net deferred tax assets 855,889 821,368 Deferred tax liabilities: Intangible assets (44,549) (24,907) Undistributed foreign earnings (41,957) (31,916) ROU assets (31,278) (25,016) Other (10,749) (8,350) Total deferred tax liabilities (128,533) (90,189) Total net deferred tax assets $ 727,356 $ 731,179 During fiscal 2020, 2019 and 2018 Cadence maintained valuation allowances of $116.4 million, $125.5 million, and $108.7 million, respectively, on certain federal, state and foreign deferred tax assets because the realization of these deferred tax assets require future income of a specific character or amount that Cadence considered uncertain. The valuation allowance primarily relates to the following: • Tax credits in certain states that are accumulating at a rate greater than Cadence’s capacity to utilize the credits and tax credits in certain states where it is likely the credits will expire unused; • Federal, state and foreign deferred tax assets related to investments and capital losses that can only be utilized against gains that are capital in nature; and • Foreign tax credits that can only be fully utilized if Cadence has sufficient income of a specific character in the future. The valuation allowance decreased by $9.1 million during fiscal 2020 and increased by $16.8 million and $13.2 million, during fiscal 2019 and fiscal 2018, respectively. The valuation allowance activity was primarily related to California research and development tax credits and certain foreign tax credits. As of January 2, 2021, Cadence’s operating loss carryforwards were as follows: Amount Expiration Periods (In thousands) Federal $ 743 from 2021 through 2029 California 27,093 from 2030 through 2039 Other states (tax effected, net of federal benefit) 1,564 from 2021 through 2037 Foreign (tax effected) 2,322 from 2025 through indefinite As of January 2, 2021, Cadence had tax credit carryforwards of: Amount Expiration Periods (In thousands) Federal* $ 96,417 from 2038 through 2040 California 63,130 indefinite Other states 12,023 from 2021 through indefinite Foreign 25,866 from 2035 through indefinite _____________ Certain of Cadence’s foreign tax credits have yet to be realized and as a result do not yet have an expiration period. Examinations by Tax Authorities Taxing authorities regularly examine Cadence’s income tax returns. As of January 2, 2021, Cadence’s earliest tax years that remain open to examination and the assessment of additional tax include: Jurisdiction Earliest Tax Year Open to Examination United States – Federal 2015 United States – California 2016 Ireland 2016 Unrecognized Tax Benefits The changes in Cadence’s gross amount of unrecognized tax benefits during fiscal 2020, 2019 and 2018 are as follows: 2020 2019 2018 (In thousands) Unrecognized tax benefits at the beginning of the fiscal year $ 106,041 $ 101,857 $ 110,179 Gross amount of the increases (decreases) in unrecognized tax benefits of tax positions taken during a prior year 5,037 (3,143) (4,183) Gross amount of the increases in unrecognized tax benefits as a result of tax positions taken during the current year 3,344 8,951 2,370 Amount of decreases in unrecognized tax benefits relating to settlements with taxing authorities, including the utilization of tax attributes (1,316) (380) — Reductions to unrecognized tax benefits resulting from the lapse of the applicable statute of limitations (676) (1,692) (5,179) Effect of foreign currency translation 591 448 (1,330) Unrecognized tax benefits at the end of the fiscal year $ 113,021 $ 106,041 $ 101,857 Total amounts of unrecognized tax benefits that, if upon resolution of the uncertain tax positions would reduce Cadence’s effective tax rate $ 66,010 $ 61,527 $ 58,022 _____________ * Includes unrecognized tax benefits of tax positions recorded in connection with acquisitions It is reasonably possible that the amount of unrecognized tax positions could decrease by approximately $10.5 million during the next 12 months. The potential decrease could be primarily driven by settlements with tax authorities. The actual amount could vary significantly depending on the ultimate timing and nature of any settlements. The total amounts of interest, net of tax, and penalties recognized in the consolidated income statements as provision (benefit) for income taxes for fiscal 2020, 2019 and 2018 were as follows: 2020 2019 2018 (In thousands) Interest $ 473 $ 490 $ 585 Penalties (3) 19 342 The total amounts of gross accrued interest and penalties recognized in the consolidated balance sheets as of January 2, 2021 and December 28, 2019 were as follows: As of January 2, December 28, (In thousands) Interest $ 3,555 $ 3,500 Penalties 12 12

Equity Method Investments and Joint Ventures [Abstract]
INVESTMENTS	INVESTMENTS Cadence has a portfolio of equity investments that includes investments in both marketable and non-marketable securities. These investments primarily consist of cash investments in companies with technologies or services that are potentially strategically important to Cadence.

Changes in the fair value of these investments is recorded to other income, net in Cadence’s consolidated income statements. Non-Marketable Equity Investments Cadence’s investments in non-marketable equity securities generally consist of stock, convertible debt or other instruments of privately held entities and are included in other assets on Cadence’s consolidated balance sheets. Cadence holds a 16% interest in a privately held company that is accounted for using the equity method of accounting. The carrying value of this investment was $130.7 million and $136.3 million as of January 2, 2021 and December 28, 2019, respectively. During fiscal 2020 and fiscal 2019, Cadence recorded losses of $4.6 million and $6.9 million, respectively, to other income, net in Cadence’s consolidated income statements, which represented Cadence’s proportionate share of net income from the investee, offset by amortization of basis differences.

The carrying value of these investments was $1.6 million and $1.9 million as of January 2, 2021 and December 28, 2019, respectively. Gains and losses on these investments are recorded to other income, net in Cadence’s consolidated income statements and were not material to Cadence’s consolidated financial statements for fiscal 2020, 2019 or 2018.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS On January 15, 2020, Cadence acquired all of the outstanding equity of AWR Corporation (“AWR”). On February 6, 2020, Cadence also acquired all of the outstanding equity of Integrand Software, Inc. (“Integrand”). These acquisitions enhance Cadence’s technology portfolio to address growing radio frequency design activity, driven by expanding use of 5G communications. The aggregate cash consideration for these acquisitions was $195.6 million, after taking into account cash acquired of $1.5 million. The total purchase consideration was allocated to the assets acquired and liabilities assumed based on their respective estimated fair values on the acquisition dates. Cadence will also make payments to certain employees, subject to continued employment and other performance-based conditions, through the first quarter of fiscal 2023. With its acquisition of AWR and Integrand, Cadence recorded $101.3 million of definite-lived intangible assets, primarily related to existing technology and customer agreements and relationships. The weighted-average amortization period for definite-lived intangible assets acquired is approximately 9 years. Cadence also recorded $119.4 million of goodwill and $25.1 million of net liabilities, consisting primarily of deferred tax liabilities, assumed deferred revenue and trade accounts receivable. The recorded goodwill is primarily related to the acquired assembled workforce and expected synergies from combining operations of the acquired companies with Cadence. None of the goodwill related to the acquisitions of AWR and Integrand will be deductible for tax purposes. Cadence completed one additional acquisition during fiscal 2020. This acquisition is not material to the consolidated financial statements. Cadence has not presented pro forma financial information for any of the businesses it acquired during fiscal 2020 because the results of operations for these businesses are not material to Cadence’s consolidated financial statements. Acquisition-Related Transaction Costs Transaction costs associated with acquisitions were $2.4 million, $2.3 million and $0.6 million during fiscal 2020, 2019 and 2018, respectively. These costs consist of professional fees and administrative costs and were expensed as incurred in Cadence’s consolidated income statements.

STOCK COMPENSATION PLANS AND STOCK-BASED COMPENSATION	STOCK COMPENSATION PLANS AND STOCK-BASED COMPENSATION Equity Incentive Plans Cadence’s Omnibus Plan provides for the issuance of both incentive and non-qualified options, restricted stock awards, restricted stock units, stock bonuses and the rights to acquire restricted stock to both executive and non-executive employees. During fiscal 2020, Cadence’s stockholders approved an amendment to the Omnibus Plan to increase the number of shares of common stock authorized for issuance by 9.0 million. As of January 2, 2021, the total number of shares available for future issuance under the Omnibus Plan was 16.2 million. Options granted under the Omnibus Plan have an exercise price not less than the fair market value of the stock on the date of grant. Options and restricted stock generally vest over a period of three years to four years. Options granted under the Omnibus Plan expire seven years from the date of grant. Vesting of restricted stock awards granted under the Omnibus Plan may require the attainment of specified performance criteria. Cadence’s 1995 Directors Stock Incentive Plan (the “Directors Plan”) provides for the issuance of non-qualified options, restricted stock awards and restricted stock units to its non-employee directors. Options granted under the Directors Plan have an exercise price not less than the fair market value of the stock on the date of grant. As of January 2, 2021, the total number of shares available for future issuance under the Directors Plan was 0.5 million. Options granted under the Directors Plan expire after ten years, and options, restricted stock awards and restricted stock units vest one year from the date of grant. Cadence has assumed certain options granted to employees of acquired companies (“Acquired Options”). The Acquired Options were assumed by Cadence outside of its stock option plans, and each option is administered under the terms of the respective original plans of the acquired companies. All of the Acquired Options have been adjusted for the price conversion under the terms of the acquisition agreement between Cadence and the relevant acquired company. If the Acquired Options are canceled, forfeited or expire, they do not become available for future grant. Stock-Based Compensation Stock-based compensation expense and the related income tax benefit recognized in connection with stock options, restricted stock and the ESPP during fiscal 2020, 2019 and 2018 were as follows: 2020 2019 2018 (In thousands) Stock options $ 8,062 $ 6,806 $ 5,581 Restricted stock 173,193 164,078 153,348 ESPP 16,013 10,663 8,786 Total stock-based compensation expense $ 197,268 $ 181,547 $ 167,715 Income tax benefit $ 31,857 $ 30,118 $ 32,830 Stock-based compensation expense is reflected in Cadence’s consolidated income statements during fiscal 2020, 2019 and 2018 as follows: 2020 2019 2018 (In thousands) Cost of product and maintenance $ 2,922 $ 2,759 $ 2,631 Cost of services 3,720 3,510 3,714 Marketing and sales 42,096 39,088 34,665 Research and development 124,999 114,656 104,353 General and administrative 23,531 21,534 22,352 Total stock-based compensation expense $ 197,268 $ 181,547 $ 167,715 Stock Options The exercise price of each stock option granted under Cadence’s employee equity incentive plans is equal to or greater than the closing price of Cadence’s common stock on the date of grant. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. The weighted-average grant date fair value of options granted and the weighted-average assumptions used in the model for fiscal 2020, 2019 and 2018 were as follows: 2020 2019 2018 Dividend yield None None None Expected volatility 25.1 % 24.4 % 24.3 % Risk-free interest rate 1.36 % 2.47 % 2.54 % Expected term (in years) 4.8 4.8 4.8 Weighted-average fair value of options granted $ 19.38 $ 14.58 $ 10.24 A summary of the changes in stock options outstanding under Cadence’s equity incentive plans during fiscal 2020 is presented below: Weighted- Average Weighted- Average Remaining Contractual Terms Aggregate Intrinsic Shares Exercise Price (Years) Value (In thousands) (In thousands) Options outstanding as of December 28, 2019 4,933 $ 26.38 Granted 534 79.82 Exercised (1,497) 17.69 Forfeited (36) 49.97 Options outstanding as of January 2, 2021 3,934 $ 36.72 3.4 $ 392,240 Options vested as of January 2, 2021 2,974 $ 28.37 2.7 $ 321,425 Cadence had total unrecognized compensation expense related to stock option grants of $15.0 million as of January 2, 2021, which will be recognized over the remaining vesting period.

Stock-based compensation expense is recognized ratably over the vesting term. The vesting of certain restricted stock grants is subject to attainment of specified performance criteria. Each fiscal quarter, Cadence estimates the probability of the achievement of these performance goals and recognizes any related stock-based compensation expense using the graded-vesting method. The amount of stock-based compensation expense recognized in any one period can vary based on the attainment or expected attainment of the various performance goals. If such performance goals are not ultimately met, no compensation expense is recognized and any previously recognized compensation expense is reversed. Certain long-term, market-based performance stock awards granted to executives vest over three to five years and are subject to certain market conditions and the executive’s continuing service to Cadence. Stock-based compensation expense is recognized straight-line over the vesting term. If the market-based performance conditions are not ultimately met, compensation expense previously recognized is not reversed. As of January 2, 2021, Cadence had 1.8 million shares of unvested long-term, market-based performance stock awards outstanding.

During the fourth quarter of fiscal 2020, Cadence initiated a restructuring plan (the “2020 Restructuring Plan”) and recorded restructuring and other charges of $10.8 million related to severance payments, termination benefits and charges related to vacated facilities. As of January 2, 2021, total liabilities related to the 2020 Restructuring Plan were $8.6 million. Cadence has also initiated restructuring plans in prior years, including both fiscal 2019 and fiscal 2018 (the “prior restructuring plans”). During fiscal 2020, Cadence revised certain estimates made in connection with the prior restructuring plans and recorded credits of $1.6 million. As of January 2, 2021, total liabilities related to the prior restructuring plans were $0.1 million.

Earnings Per Share [Abstract]
NET INCOME PER SHARE	NET INCOME PER SHARE Basic net income per share is computed by dividing net income during the period by the weighted-average number of shares of common stock outstanding during that period, less unvested restricted stock awards. Diluted net income per share is impacted by equity instruments considered to be potential common shares, if dilutive, computed using the treasury stock method of accounting. The calculations for basic and diluted net income per share for fiscal 2020, 2019 and 2018 are as follows: 2020 2019 2018 (In thousands, except per share amounts) Net income $ 590,644 $ 988,979 $ 345,777 Weighted-average common shares used to calculate basic net income per share 273,728 273,239 273,729 Stock-based awards 5,913 7,276 7,415 Weighted-average common shares used to calculate diluted net income per share 279,641 280,515 281,144 Net income per share – basic $ 2.16 $ 3.62 $ 1.26 Net income per share – diluted $ 2.11 $ 3.53 $ 1.23 The following table presents shares of Cadence’s common stock outstanding for fiscal 2020, 2019 and 2018 that were excluded from the computation of diluted net income per share because the effect of including these shares in the computation of diluted net income per share would have been anti-dilutive: 2020 2019 2018 (In thousands) Long-term market-based awards 383 1,097 50 Options to purchase shares of common stock 201 359 637 Non-vested shares of restricted stock 58 727 290 Total potential common shares excluded 642 2,183 977

Fair Value

Fair Value	12 Months Ended
Fair Value	Jan. 02, 2021
Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE Inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Cadence’s market assumptions. These two types of inputs have created the following fair value hierarchy: • Level 1 – Quoted prices for identical instruments in active markets; • Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and • Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. The valuation techniques used to determine the fair value of Cadence’s 2024 Notes are classified within Level 2 of the fair value hierarchy. For additional information relating to Cadence’s debt arrangements, see Note 3 in the notes to consolidated financial statements. This hierarchy requires Cadence to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. Cadence recognizes transfers between levels of the hierarchy based on the fair values of the respective financial instruments at the end of the reporting period in which the transfer occurred. There were no transfers between levels of the fair value hierarchy during fiscal 2020. On a quarterly basis, Cadence measures at fair value certain financial assets and liabilities. The fair value of financial assets and liabilities was determined using the following levels of inputs as of January 2, 2021 and December 28, 2019: Fair Value Measurements as of January 2, 2021: Total Level 1 Level 2 Level 3 (In thousands) Assets Cash equivalents: Money market funds $ 541,386 $ 541,386 $ — $ — Marketable equity securities 4,452 4,452 — — Securities held in NQDC trust 42,769 42,769 — — Foreign currency exchange contracts 8,868 — 8,868 — Total Assets $ 597,475 $ 588,607 $ 8,868 $ — As of January 2, 2021, Cadence did not have any financial liabilities requiring a recurring fair value measurement. Fair Value Measurements as of December 28, 2019: Total Level 1 Level 2 Level 3 (In thousands) Assets Cash equivalents: Money market funds $ 445,942 $ 445,942 $ — $ — Marketable equity securities 4,600 4,600 — — Securities held in NQDC trust 34,096 34,096 — — Foreign currency exchange contracts 3,557 — 3,557 — Total Assets $ 488,195 $ 484,638 $ 3,557 $ — As of December 28, 2019, Cadence did not have any financial liabilities requiring a recurring fair value measurement. Level 1 Measurements Cadence’s cash equivalents held in money market funds, marketable equity securities and the trading securities held in Cadence’s NQDC trust are measured at fair value using level 1 inputs. Level 2 Measurements The valuation techniques used to determine the fair value of Cadence’s foreign currency forward exchange contracts and 2024 Notes are classified within Level 2 of the fair value hierarchy. For additional information relating to Cadence’s debt arrangements, see Note 3 in the notes to consolidated financial statements. Level 3 Measurements Cadence acquired intangible assets of $101.3 million during the first quarter of fiscal 2020 with its acquisition of AWR and Integrand. The fair value of the definite-lived intangible assets acquired with these acquisitions was determined using variations of the income approach, which include level 3 inputs. For existing technology, the fair value was determined by applying the relief-from-royalty method. This method is based on the application of a royalty rate to forecasted revenue to quantify the benefit of owning the intangible asset rather than paying a royalty for use of the asset. To estimate royalty savings over time, Cadence projected revenue from existing technology over the estimated remaining life of the technology, including the effect of technological obsolescence which was estimated at rate between 5% and 7.5% annually, before applying an assumed royalty rate of 20%. The present value of after-tax royalty savings were determined using discount rates ranging from 10% to 11.5%. The fair value for customer contracts and related relationships was determined by using the multi-period excess earnings method. This method reflects the present value of the projected cash flows that are expected to be generated from existing customers, less charges representing the contribution of other assets to those cash flows. Projected income from existing customer relationships considered customer retention rates ranging between 85% and 95%. The present value of operating cash flows from existing customers was determined using discount rates 10% and 11.5%. Cadence also assumed obligations related to deferred revenue of $6.9 million during the first quarter of fiscal 2020 with its acquisition of AWR. The fair value of these obligations was estimated using the cost build-up approach. The cost build-up approach determines fair value using estimates of the costs required to fulfill the contracted obligations plus an assumed profit margin, which approximates the amount that AWR would be required to pay a third party to assume the obligation. Cadence believes that its estimates and assumptions related to the fair value of its acquired intangible assets and deferred revenue obligations are reasonable, but significant judgment is involved.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Purchase Obligations Cadence had purchase obligations of $46.8 million as of January 2, 2021 that were associated with agreements or commitments for purchases of goods or services. Legal Proceedings From time to time, Cadence is involved in various disputes and litigation that arise in the ordinary course of business. These include disputes and lawsuits related to intellectual property, indemnification obligations, mergers and acquisitions, licensing, contracts, distribution arrangements and employee relations matters. At least quarterly, Cadence reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on Cadence’s judgments using the best information available at the time. As additional information becomes available, Cadence reassesses the potential liability related to pending claims and litigation matters and may revise estimates. Other Contingencies Cadence provides its customers with a warranty on sales of hardware products, generally for a 90-day period. Cadence did not incur any significant costs related to warranty obligations during fiscal 2020, 2019 or 2018. Cadence’s product license and services agreements typically include a limited indemnification provision for claims from third parties relating to Cadence’s intellectual property. If the potential loss from any indemnification claim is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. The indemnification is generally limited to the amount paid by the customer. Cadence did not incur any significant losses from indemnification claims during fiscal 2020, 2019 or 2018.

For employees in the United States, Cadence maintains a 401(k) savings plan to provide retirement benefits through tax-deferred salary deductions and may make discretionary contributions, as determined by the Board of Directors, which cannot exceed a specified percentage of the annual aggregate salaries of those employees eligible to participate. Cadence’s total contributions made to these plans during fiscal 2020, 2019 and 2018 were as follows: 2020 2019 2018 (In thousands) Contributions to defined contribution plans $ 27,152 $ 25,269 $ 25,731 Executive Officers and Directors may also elect to defer compensation payable to them under Cadence’s NQDC. Deferred compensation payments are held in investment accounts and the values of the accounts are adjusted each quarter based on the fair value of the investments held in the NQDC. These investments are classified in other assets in the consolidated balance sheets and gains and losses are recognized as other income, net in the consolidated income statements. Certain of Cadence’s international subsidiaries sponsor defined benefit retirement plans. The unfunded projected benefit obligation for Cadence’s defined benefit retirement plans is recorded in other long-term liabilities in the consolidated balance sheets.

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING Segment reporting is based on the “management approach,” following the method that management organizes the company’s reportable segments for which separate financial information is made available to, and evaluated regularly by, the chief operating decision maker in allocating resources and in assessing performance. Cadence’s chief operating decision maker is its CEO, who reviews Cadence’s consolidated results as one operating segment. In making operating decisions, the CEO primarily considers consolidated financial information, accompanied by disaggregated information about revenues by geographic region. Outside the United States, Cadence markets and supports its products and services primarily through its subsidiaries. Revenue is attributed to geography based upon the country in which the product is used, or services are delivered. Property, plant and equipment assets are attributed to geography based on the country where the assets are located. The following table presents a summary of revenue by geography for fiscal 2020, 2019 and 2018: 2020 2019 2018 (In thousands) Americas: United States $ 1,096,263 $ 982,380 $ 924,644 Other Americas 43,652 43,473 32,531 Total Americas 1,139,915 1,025,853 957,175 Asia: China 406,645 241,474 210,194 Other Asia 487,362 459,028 395,221 Total Asia 894,007 700,502 605,415 Europe, Middle East and Africa 469,804 433,314 406,877 Japan 179,165 176,650 168,555 Total $ 2,682,891 $ 2,336,319 $ 2,138,022 The following table presents a summary of property, plant and equipment assets by geography as of January 2, 2021, December 28, 2019 and December 29, 2018: As of January 2, December 28, December 29, (In thousands) Americas: United States $ 248,292 $ 220,023 $ 200,025 Other Americas 753 728 475 Total Americas 249,045 220,751 200,500 Asia: China 16,416 15,729 9,608 Other Asia 28,668 27,890 30,021 Total Asia 45,084 43,619 39,629 Europe, Middle East and Africa 16,304 10,474 11,784 Japan 692 1,011 717 Total* $ 311,125 $ 275,855 $ 252,630

SUBSEQUENT EVENTS	SUBSEQUENT EVENT On January 18, 2021, Cadence entered into a definitive agreement to acquire all of the outstanding equity of Belgium-based Numerical Mechanics Applications International SA (“NUMECA”), a leader in computational fluid dynamics (“CFD”), mesh generation, multi-physics simulation and optimization. This addition of NUMECA’s technologies and talent supports Cadence’s Intelligent System Design™ strategy and broadens its System Design and Analysis technology portfolio with the addition of CFD solutions. The acquisition of NUMECA is expected to close during the first quarter of fiscal 2021, subject to customary closing conditions, and is expected to be funded through cash on hand. Due to the timing of the acquisition, the initial accounting for the acquisition is incomplete. As such, Cadence is not able to disclose certain information relating to the acquisition, including the preliminary fair value of assets acquired and liabilities assumed.

Accounting Policies [Abstract]
Commitments and Contingencies	At least quarterly, Cadence reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on Cadence’s judgments using the best information available at the time. As additional information becomes available, Cadence reassesses the potential liability related to pending claims and litigation matters and may revise estimates.
Fair Value of Financial Instruments	Inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Cadence’s market assumptions. These two types of inputs have created the following fair value hierarchy: • Level 1 – Quoted prices for identical instruments in active markets; • Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and • Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. The valuation techniques used to determine the fair value of Cadence’s 2024 Notes are classified within Level 2 of the fair value hierarchy. For additional information relating to Cadence’s debt arrangements, see Note 3 in the notes to consolidated financial statements.
Principles of Consolidation and Basis of Presentation	The consolidated financial statements include the accounts of Cadence and its subsidiaries after elimination of intercompany accounts and transactions. All consolidated subsidiaries are wholly owned by Cadence. Cadence’s fiscal years are 52- or 53-week periods ending on the Saturday closest to December 31. Fiscal 2020 was a 53- week year, while 2019 and 2018 were each 52-week fiscal years.
Use of Estimates	Preparation of the consolidated financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Recently Adopted Accounting Standards	Credit Losses In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” which required the establishment of an allowance for estimated credit losses on financial assets, including trade and other receivables, at each reporting date. Cadence adopted the new standard on December 29, 2019, the first day of fiscal 2020, and recorded a cumulative-effect adjustment to decrease retained earnings in the amount of $2.0 million for expected credit losses on financial assets at the adoption date. The adoption of this standard required Cadence to modify its existing process for establishing credit losses on trade receivables, including receivables derived from leasing arrangements for its emulation and prototyping hardware. Goodwill Impairment In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” that eliminates “Step 2” from the goodwill impairment test. Cadence adopted the new standard on December 29, 2019, the first day of fiscal 2020. The new standard did not have an impact on Cadence’s consolidated financial statements and related disclosures. Fair Value Measurements In August 2018, the FASB issued ASU 2018-13, “Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement,” which modifies the disclosure requirements on fair value measurements. Cadence adopted the new standard on December 29, 2019, the first day of fiscal 2020. The new standard did not have a material impact on Cadence’s consolidated financial statements and related disclosures. Implementation Costs Incurred in a Cloud Computing Arrangement In August 2018, the FASB issued ASU 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” which clarifies the accounting for implementation costs in cloud computing arrangements. The new standard aligns the treatment of implementation costs incurred by customers in cloud computing arrangements that are service contracts with the treatment of similar costs incurred to develop or obtain internal-use software. Under the new standard, implementation costs are deferred and presented in the same financial statement caption on the condensed consolidated balance sheet as a prepayment of related arrangement fees. The deferred costs are recognized over the term of the arrangement in the same financial statement caption in the condensed consolidated income statement as the related fees of the arrangement. Cadence adopted the new standard on December 29, 2019, the first day of fiscal 2020. The new standard did not have a material impact on Cadence’s condensed consolidated financial statements and related disclosures. New Accounting Standards Not Yet Adopted Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes,” which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. The new standard is effective for fiscal years beginning after December 15, 2020. Most amendments within the standard are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. Cadence is currently evaluating the impacts of the provisions of this standard on its financial condition, results of operations and cash flows.
Foreign Operations	Cadence transacts business in various foreign currencies. The United States dollar is the functional currency of Cadence’s consolidated entities operating in the United States and certain of its consolidated subsidiaries operating outside the United States. The functional currency for Cadence’s other consolidated entities operating outside of the United States is generally the country’s local currency. Cadence translates the financial statements of consolidated entities whose functional currency is not the United States dollar into United States dollars. Cadence translates assets and liabilities at the exchange rate in effect as of the financial statement date and translates income statement accounts using an average exchange rate for the period. Cadence includes adjustments from translating assets and liabilities into United States dollars, and the effect of exchange rate changes on intercompany transactions of a long-term investment nature in stockholders’ equity as a component of accumulated other comprehensive income. Cadence reports gains and losses from foreign exchange rate changes related to intercompany receivables and payables that are not of a long-term investment nature, as well as gains and losses from foreign currency transactions of a monetary nature in other income, net, in the consolidated income statements.
Concentrations of Credit Risk	Financial instruments, including derivative financial instruments, that may potentially subject Cadence to concentrations of credit risk, consist principally of cash and cash equivalents, accounts receivable, investments and forward contracts. Credit exposure related to Cadence’s foreign currency forward contracts is limited to the realized and unrealized gains on these contracts.
Cash and Cash Equivalents	Cadence considers all highly liquid investments with original maturities of three months or less on the date of purchase to be cash equivalents. Book overdraft balances are recorded in accounts payable and accrued liabilities in the consolidated balance sheets and are reported as a component of cash flows from financing activities in the consolidated statement of cash flows.
Receivables	Cadence’s receivables, net includes invoiced accounts receivable and the current portion of unbilled receivables. Unbilled receivables represent amounts Cadence has recorded as revenue for which payments from a customer are due over time and Cadence has an unconditional right to the payment. Cadence’s accounts receivable and unbilled receivables were initially recorded at the transaction value. Cadence’s long-term receivables balance includes receivable balances to be invoiced more than one year after each balance sheet date.
Allowance for Doubtful Accounts	Cadence assesses its ability to collect outstanding receivables and provides customer-specific allowances, allowances for credit losses and general allowances for the portion of its receivables that are estimated to be uncollectible. The allowances are based on the current creditworthiness of its customers, historical experience, expected credit losses, changes in customer demand and the overall economic climate in the industries that Cadence serves. Provisions for these allowances are recorded in general and administrative expense in Cadence’s consolidated income statements.
Inventories	Inventories are computed at standard costs which approximate actual costs and are valued at the lower of cost or net realizable value based on the first-in, first-out method. Cadence’s inventories include high technology parts and components for complex emulation and prototyping hardware systems. These parts and components are specialized in nature and may be subject to rapid technological obsolescence. While Cadence has programs to minimize the required inventories on hand and considers technological obsolescence when estimating required reserves to reduce recorded amounts to market values, it is reasonably possible that such estimates could change in the near term. Cadence’s policy is to reserve for inventory in excess of 12-month demand or for other known obsolescence or realization issues.
Property, Plant and Equipment	Property, plant and equipment is stated at historical cost. Depreciation and amortization are generally provided over the estimated useful lives, using the straight-line method, as follows: Computer equipment and related software 2-7 years Buildings 25-32 years Leasehold improvements Shorter of the lease term or the estimated useful life Building improvements and land improvements Up to 32 years Furniture and fixtures 3-5 years Equipment 3-5 years Cadence capitalizes certain costs of software developed for internal use. Capitalization of software developed for internal use begins at the application development phase of the project. Amortization begins when the computer software is substantially complete and ready for its intended use. Amortization is recorded on a straight-line basis over the estimated useful life. Cadence capitalized costs of software developed for internal use of $0.9 million, $2.4 million, and $3.6 million during fiscal 2020, 2019 and 2018, respectively. Cadence recorded depreciation and amortization expense of $67.6 million, $63.3 million and $60.4 million during fiscal 2020, 2019 and 2018, respectively, for property, plant and equipment.
Software Development Costs	Software development costs are capitalized beginning when a product’s technological feasibility has been established by completion of a working model of the product and amortization begins when a product is available for general release to customers. The period between the achievement of technological feasibility and the general release of Cadence’s products has typically been of short duration. Costs incurred during fiscal 2020, 2019 and 2018 were not material.
Deferred Sales Commisions	Cadence records an asset for the incremental costs of obtaining a contract with a customer, including direct sales commissions that are earned upon execution of the contract. Cadence uses the portfolio method to recognize the amortization expense related to these capitalized costs related to initial contracts and renewals and such expense is recognized over a period associated with the revenue of the related portfolio, which is generally two to three years for Cadence’s software arrangements and upon delivery for its hardware and IP arrangements. Incremental costs related to initial contracts and renewals are amortized over the period of the arrangement in each case because Cadence pays the same commission rate for both new contracts and renewals. Deferred sales commissions are tested for impairment on an ongoing basis when events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment is recognized to the extent that the amount of deferred sales commission exceeds the remaining expected gross margin (remaining revenue less remaining direct costs) on the goods and services to which the deferred sales commission relates. Total capitalized costs were $36.7 million and $31.6 million as of January 2, 2021, and December 28, 2019, respectively, and are included in other assets in Cadence’s consolidated balance sheet. Amortization of these assets was $34.6 million, $29.4 million and $26.5 million during fiscal 2020, 2019 and 2018, respectively, and is included in sales and marketing expense in Cadence’s consolidated income statement.
Goodwill	Cadence conducts a goodwill impairment analysis annually and as necessary if changes in facts and circumstances indicate that the fair value of Cadence’s single reporting unit may be less than its carrying amount. To assess for impairment, Cadence compares the estimated fair value of its single reporting unit to the carrying value of the reporting unit’s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further analysis is required. If the fair value of the reporting unit is less than the carrying value of its net assets, Cadence would be required to record an impairment charge.
Long-lived Assets, Including Acquired Intangibles	Cadence’s long-lived assets consist of property, plant and equipment, and acquired intangibles. Acquired intangibles with definite lives are amortized on a straight-line basis over the estimated economic life of the underlying products and technologies, which range from three
Lessee Considerations	Lessee Considerations Cadence has operating leases primarily consisting of facilities with remaining lease terms of approximately one year to fifteen years. Cadence has options to terminate many of its leases early. The lease term represents the period up to the early termination date unless it is reasonably certain that Cadence will not exercise the early termination option. For certain leases, Cadence has options to extend the lease term for additional periods ranging from one year to ten years. These renewal options are not considered in the remaining lease term unless it is reasonably certain that Cadence will exercise such options. At inception of a contract, Cadence determines an arrangement contains a lease if the arrangement conveys the right to use an identified asset and Cadence obtains substantially all of the economic benefits from the asset and has the ability to direct the use of the asset. Leases with an initial term of twelve months or less are not recorded on the balance sheet. For lease agreements entered into or reassessed after the adoption of Topic 842, Cadence combines the lease and non-lease components in determining the lease liabilities and right-of-use (“ROU”) assets. Non-lease components primarily include common-area maintenance and other management fees. Operating lease expense is generally recognized evenly over the term of the lease. Payments under Cadence's lease agreements are primarily fixed; however, certain agreements contain rental payments that are adjusted periodically based on changes in consumer price and other indices. Changes to payments resulting from changes in indices are expensed as incurred and not included in the measurement of lease liabilities and ROU assets. Cadence’s lease agreements do not provide an implicit borrowing rate, therefore an internal incremental borrowing rate is determined based on information available at lease commencement date for purposes of determining the present value of lease payments. The incremental borrowing rate represents a comparable rate to borrow on a collateralized basis over a similar term and in the economic environment where the leased asset is located. Cadence used the incremental borrowing rate on the effective date of adoption of Topic 842 for all leases that commenced prior to that date.
Lessor Considerations	Lessor Considerations Although most of Cadence’s revenue from its hardware business comes from sales of hardware, Cadence also leases its hardware products to some customers. Cadence determines the existence of a lease when the customer controls the use of the identified hardware for a period of time defined in the lease agreement. Cadence’s leases range in duration up to three years with payments generally collected in equal quarterly installments. Cadence’s leases do not include termination rights or variable pricing and typically do not include purchase rights at the end of the lease. Short-term leases are usually less than two years and are classified as operating leases with revenue recognized and depreciation expensed on a straight-line basis over the term of the lease. Long-term leases are typically for three years and are classified as sales-type leases with revenue and cost of sales recognized upon delivery.
Investments in Equity Securities	Cadence’s investments in marketable equity securities are carried at fair value as a component of prepaid expenses and other in the consolidated balance sheets. Cadence records realized and unrealized holding gains or losses as part of other income, net in the consolidated income statements. Cadence’s non-marketable investments include its investments in privately held companies. These investments are initially recorded at cost and are included in other assets in the consolidated balance sheets. Cadence accounts for these investments using the measurement alternative when the fair value of the investment is not readily determinable and Cadence does not have the ability to exercise significant influence or the equity method of accounting when it is determined that Cadence has the ability to exercise significant influence. For investments accounted for using the equity method of accounting, Cadence records its proportionate share of the investee’s income or loss, net of the effects of any basis differences, to other income, net on a one-quarter lag in Cadence’s consolidated income statements.
Derivative Financial Instruments	Cadence enters into foreign currency forward exchange contracts with financial institutions to protect against currency exchange risks associated with existing assets and liabilities. A foreign currency forward exchange contract acts as a hedge by increasing in value when underlying assets decrease in value or underlying liabilities increase in value due to changes in foreign exchange rates. Conversely, a foreign currency forward exchange contract decreases in value when underlying assets increase in value or underlying liabilities decrease in value due to changes in foreign exchange rates. The forward contracts are not designated as accounting hedges and, therefore, the unrealized gains and losses are recognized in other income, net, in advance of the actual foreign currency cash flows. The fair value of these forward contracts is recorded in accrued liabilities or in other current assets. These forward contracts generally have maturities of 90 days or less.
Nonqualified Deferred Compensation Trust	Executive officers, senior management and members of Cadence’s Board of Directors may elect to defer compensation payable to them under Cadence’s Nonqualified Deferred Compensation Plan (“NQDC”). Deferred compensation payments are held in investment accounts and the values of the accounts are adjusted each quarter based on the fair value of the investments held in the NQDC. The selected investments held in the NQDC accounts are carried at fair value, with the unrealized gains and losses recognized in the consolidated income statements as other income, net. These securities are classified in other assets in the consolidated balance sheets because they are not available for Cadence’s use in its operations. Cadence’s obligation with respect to the NQDC trust is recorded in other long-term liabilities on the consolidated balance sheets. Increases and decreases in the NQDC trust liability are recorded as compensation expense in the consolidated income statements.
Treasury Stock	Cadence generally issues shares related to its stock-based compensation plans from shares held in treasury. When treasury stock is reissued at an amount higher than its cost, the difference is recorded as a component of capital in excess of par in the consolidated statements of stockholders’ equity. When treasury stock is reissued at an amount lower than its cost, the difference is recorded as a component of capital in excess of par to the extent that gains exist to offset the losses. If there are no accumulated treasury stock gains in capital in excess of par, the losses upon reissuance of treasury stock are recorded as a component of retained earnings in the consolidated statements of stockholders’ equity. There were no losses recorded as a component of retained earnings by Cadence on the reissuance of treasury stock during fiscal 2020, 2019 or 2018.
Stock-Based Compensation	Cadence recognizes the cost of awards of equity instruments granted to employees in exchange for their services as stock-based compensation expense. Stock-based compensation expense is measured at the grant date based on the value of the award and is recognized as expense over the requisite service period, which is typically the vesting period. Cadence recognizes stock-based compensation expense on the straight-line method for awards that only contain a service condition and on the graded-vesting method for awards that contain both a service and performance condition. Cadence recognizes the impact of forfeitures on stock-based compensation expense as they occur.The fair value of stock options and purchase rights issued under Cadence’s Employee Stock Purchase Plan (“ESPP”) are calculated using the Black-Scholes option pricing model. The computation of the expected volatility assumption used for new awards is based on implied volatility when the remaining maturities of the underlying traded options are at least one year. When the remaining maturities of the underlying traded options are less than one year, expected volatility is based on a weighting of historical and implied volatilities. When determining the expected term, Cadence reviews historical employee exercise behavior from options having similar vesting periods. The risk-free interest rate for the period within the expected term of the option is based on the yield of United States Treasury notes for the comparable term in effect at the time of grant. The expected dividend yield used in the calculation is zero because Cadence has not historically paid and currently does not expect to pay dividends in the foreseeable future.
Advertising	Cadence expenses the costs of advertising as incurred. Total advertising expense, including marketing programs and events, was $7.1 million, $8.4 million and $7.6 million during fiscal 2020, 2019 and 2018, respectively, and is included in marketing and sales in the consolidated income statements.
Restructuring Charges	Cadence records personnel-related restructuring charges with termination benefits when the costs are both probable and estimable. Cadence records personnel-related restructuring charges with non-customary termination benefits when the plan has been communicated to the affected employees. Cadence records facilities-related restructuring charges in the period in which the affected facilities are vacated. In connection with facilities-related restructuring plans, Cadence has made a number of estimates and assumptions related to losses on excess facilities that have been vacated or consolidated, particularly the timing of subleases and sublease terms. Closure and space reduction costs included in the restructuring charges include payments required under leases less any applicable estimated sublease income after the facilities are abandoned, lease buyout costs and certain contractual costs to maintain facilities during the period after abandonment. Cadence records estimated provisions for termination benefits and outplacement costs along with other personnel-related restructuring costs, asset impairments related to abandoned assets and other costs associated with the restructuring plan. Cadence regularly evaluates the adequacy of its restructuring liabilities and adjusts the balances based on actual costs incurred or changes in estimates and assumptions. Subsequent adjustments to restructuring accruals are classified in restructuring and other charges in the consolidated income statements.
Accounting for Income Taxes	Cadence accounts for the effect of income taxes in its consolidated financial statements using the asset and liability method. This process involves estimating actual current tax liabilities together with assessing carryforwards and temporary differences resulting from differing treatment of items, such as depreciation, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, measured using enacted tax rates expected to apply to taxable income in the years when those temporary differences are expected to be recovered or settled. Cadence accounts for the United States global intangible low-taxed income as a period expense. Cadence then records a valuation allowance to reduce the deferred tax assets to the amount that Cadence believes is more likely than not to be realized based on its judgment of all available positive and negative evidence. The weight given to the potential effect of negative and positive evidence is commensurate with the extent to which the strength of the evidence can be objectively verified. This assessment, which is completed on a taxing jurisdiction basis, takes into account a number of types of evidence, including the following: • the nature and history of current or cumulative financial reporting income or losses; • sources of future taxable income; • the anticipated reversal or expiration dates of the deferred tax assets; and • tax planning strategies. Cadence takes a two-step approach to recognizing and measuring the financial statement benefit of uncertain tax positions. The first step is to evaluate the tax position for recognition by determining whether the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement of the audit. Cadence classifies interest and penalties on unrecognized tax benefits as income tax expense or benefit. For additional discussion of income taxes, see Note 6 in the notes to the consolidated financial statements.
Revenue from Contract with Customer	Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration to which Cadence expects to be entitled in exchange for promised goods or services. Cadence’s performance obligations are satisfied either over time or at a point in time. In any fiscal year, between 85% and 90% of revenue is characterized as recurring revenue. Revenue characterized as recurring includes revenue recognized over time from Cadence’s software arrangements, services, royalties, maintenance on IP licenses and hardware, and operating leases of hardware and revenue recognized at varying points in time over the term of our IP Access Agreements (“IPAA”). The remainder of Cadence’s revenue is characterized as up-front revenue. Up-front revenue is primarily generated by sales of emulation and prototyping hardware and individual IP licenses. Product and maintenance revenue includes Cadence’s licenses of software and IP, sales of emulation hardware and the related maintenance on these licenses and sales. Service revenue includes revenue received for performing engineering services (which are generally not related to the functionality of other licensed products), customized IP on a fixed fee basis, and sales from cloud-based solutions that provide customers with software and services over a period of time. Cadence enters into contracts that can include various combinations of licenses, products and services, some of which are distinct and are accounted for as separate performance obligations. For contracts with multiple performance obligations, Cadence allocates the transaction price of the contract to each performance obligation, generally on a relative basis using its SSP. We generate revenue from contracts with customers and apply judgement in identifying and evaluating any terms and conditions in contracts which may impact revenue recognition. Revenue is recognized net of any taxes collected from customers that are subsequently remitted to governmental authorities. Software Revenue Recognition Cadence’s time-based license arrangements grant customers the right to access and use all of the licensed products at the outset of an arrangement and updates are generally made available throughout the entire term of the arrangement, which is generally two to three years. Cadence’s updates provide continued access to evolving technology as customers’ designs migrate to more advanced nodes and as its customers’ technological requirements evolve. In addition, certain time-based license arrangements include remix rights and unspecified additional products that become commercially available during the term of the agreement. Payments are generally received in equal or near equal installments over the term of the agreement. Multiple software licenses, related updates, and technical support in these time-based arrangements constitute a single, combined performance obligation and revenue is recognized over the term of the license, commencing upon the later of the effective date of the arrangement 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 time-based pattern of transfer to the customer. Hardware Revenue Recognition Cadence generally has two performance obligations in arrangements involving the sale or lease of hardware products. The first performance obligation is to transfer the hardware product (which includes software integral to the functionality of the hardware product). The second performance obligation is to provide maintenance on hardware and its embedded software, which includes 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 transaction price allocated to the hardware product is generally recognized as revenue at the time of delivery because the customer obtains control of the product at that point in time. Cadence has concluded that control generally transfers at that point in time because the customer has title to the hardware, physical possession, and a present obligation to pay for the hardware. The transaction price allocated to maintenance is recognized as revenue ratably over the maintenance term. Payments for hardware contracts are generally received upon delivery of the hardware product. Shipping and handling costs are considered fulfillment costs and are included in cost of product and maintenance in Cadence’s consolidated income statements. IP Revenue Recognition Cadence generally licenses IP under nonexclusive license agreements that provide usage rights for specific designs. In addition, for certain of Cadence’s IP license agreements, royalties are collected as customers ship their own products that incorporate Cadence IP. These arrangements generally have two performance obligations—transferring the licensed IP and associated maintenance, which includes rights to technical support, and software updates that are all provided over the maintenance term and have a time-based pattern of transfer to the customer. Some customers enter into a non-cancellable IPAA 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 IP products or services. These arrangements do not meet the definition of a revenue contract until the customer executes a separate selection form to identify the products and services that they are purchasing. Each separate selection form under the IPAA is treated as an individual contract and accounted for based on the respective performance obligations. Revenue allocated to the IP license is recognized at a point in time upon the later of the delivery of the IP or the beginning of the license period and revenue allocated to the maintenance is recognized over the maintenance term. Royalties are recognized as revenue in the quarter in which the applicable Cadence customer ships its products that incorporate Cadence IP. Payments for IP contracts are generally received upon delivery of the IP. Cadence customizes certain IP and revenue related to this customization is recognized as services revenue as described below. Services Revenue Recognition Revenue from service contracts is recognized over time, generally using costs incurred or hours expended to measure progress. Cadence 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 and specification and testing requirement changes. Payments for services are generally due upon milestones in the contract or upon consumption of the hourly resources.
