Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Dec. 28, 2019
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. 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.
Principles of Consolidation and Basis of Presentation | 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 2019, 2018 and 2017 were each 52-week fiscal years.
Use of Estimates | 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.
Comparability | Comparability Prior period balances for deferred tax assets in Cadence’s consolidated balance sheets have been reclassified to conform to the current period presentation. Effective the first day of fiscal 2019, Cadence adopted multiple new accounting standards. Prior periods were not retrospectively restated, so the consolidated balance sheet as of December 28, 2019 was prepared using accounting standards that were different than those in effect as of December 29, 2018. Therefore, the consolidated balance sheets as of December 28, 2019 and December 29, 2018 are not directly comparable. Cadence also adopted multiple new accounting standards on the first day of fiscal 2018, including standards related to revenue recognition and accounting for income taxes. Prior periods were not retrospectively restated, so the consolidated balance sheets as of December 28, 2019 and December 29, 2018, are not directly comparable to the consolidated balance sheet as of December 30, 2017, nor are the results of operations for fiscal 2019 and fiscal 2018 directly comparable to the results of operations for fiscal 2017.
Recently Adopted Accounting Standards | Recently Adopted Accounting Standards Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued accounting standards update (“ASU”) 2016-02, “Leases (Topic 842)” (“Topic 842”), which requires the recognition of right-of-use (“ROU”) assets and lease liabilities on the balance sheet. The most prominent of the changes in the standard is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Cadence adopted the new standard on December 30, 2018, the first day of fiscal 2019, and used the modified retrospective approach with the effective date as the date of initial application. Consequently, prior period balances and disclosures have not been restated. Cadence elected certain practical expedients, which among other things, allowed it to carry forward prior conclusions about lease identification and classification. Adoption of the standard resulted in the balance sheet recognition of additional lease assets and lease liabilities of approximately $80 million; however, the adoption of the standard did not have an impact on Cadence’s beginning retained earnings, results from operations or cash flows. Additionally, the new standard did not have a material impact on the consolidated financial statements for arrangements in which Cadence is the lessor. For additional information regarding Cadence’s leases, see Note 7 in the notes to consolidated financial statements. Income Tax Effects within Accumulated Other Comprehensive income In February 2018, the FASB issued ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which allows a reclassification of the income tax effects of the U.S. Tax Cuts and Jobs Act (the “Tax Act”) on items within accumulated other comprehensive income to retained earnings. This standard became effective for Cadence on December 30, 2018, the first day of fiscal 2019. The adoption of this standard did not have a material impact on Cadence’s consolidated financial statements.
Foreign Operations | 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 | 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 | 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 | 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 | Allowances for Doubtful Accounts Each fiscal quarter, Cadence assesses its ability to collect outstanding receivables, and provides allowances for a portion of its receivables when collection is not probable. Cadence analyzes the creditworthiness of its customers, historical experience, changes in customer demand and the overall economic climate in the industries that Cadence serves. Provisions are made based upon a specific review of customer receivables and are recorded in general and administrative expenses.
Inventories | Inventories Inventories are stated at the lower of cost or net realizable value. 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 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 $2.4 million, $3.6 million, and $2.2 million during fiscal 2019, 2018 and 2017, respectively. Cadence recorded depreciation and amortization expense of $63.3 million, $60.4 million and $52.9 million during fiscal 2019, 2018 and 2017, respectively, for property, plant and equipment.
Software Development Costs | 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 2019, 2018 and 2017 were not material.
Commissions Expense | 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 $31.6 million and $31.2 million as of December 28, 2019, and December 29, 2018, respectively, and are included in other assets in Cadence’s consolidated balance sheet. Amortization of these assets was $29.4 million and $26.5 million during fiscal 2019 and 2018, respectively, and is included in sales and marketing expense in Cadence’s consolidated income statement.
Goodwill | 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. Cadence’s goodwill impairment test consists of two steps. The first step requires that Cadence compare 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 testing 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 complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded.
Long-lived Assets, Including Acquired Intangibles | 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 two years to fourteen years. Acquired intangibles with indefinite lives, or in-process technology, consists of projects that had not reached technological feasibility by the date of acquisition. Upon completion of the project, the assets are amortized over their estimated useful lives. If the project is abandoned rather than completed, the asset is written off. In-process technology is tested for impairment annually and as necessary if changes in facts and circumstances indicate that the assets might be impaired. 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
Lessee Considerations | Lessee Considerations Cadence has operating leases primarily consisting of facilities with remaining lease terms of approximately one year to eleven 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 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 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. 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 | 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 other-than-temporarily 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, and that difference is other than temporary, Cadence writes down the value of the investment to its fair value. Cadence records investment write-downs in other income, net, in the consolidated income statements.
Derivative Financial Instruments | 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 | 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 | 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 2019, 2018 or 2017.
Revenue Recognition | 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. Revenue from performance obligations delivered to customers over time accounted for approximately 85% of Cadence’s total revenue for fiscal 2019 and 2018. 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. 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 IP Access Agreement (“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.
Revenue Net of Taxes Collected | Revenue is recognized net of any taxes collected from customers that are subsequently remitted to governmental authorities.
Shipping and Handling Cost | Shipping and handling costs are considered fulfillment costs and are included in cost of product and maintenance in Cadence’s consolidated income statements.
Stock-Based Compensation | 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 | Advertising Cadence expenses the costs of advertising as incurred. Total advertising expense, including marketing programs and events, was $8.4 million, $7.6 million and $7.4 million during fiscal 2019, 2018 and 2017, respectively, and is included in marketing and sales in the consolidated income statements.
Restructuring Charges | 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 lease loss accruals and severance and related benefits accruals, 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 | 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.
