Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared by Cadence Design Systems, Inc. (“Cadence”) without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. However, Cadence believes that the disclosures contained in this Quarterly Report on Form 10-Q comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”) for a Quarterly Report on Form 10-Q and are adequate to make the information presented not misleading. These condensed consolidated financial statements are meant to be, and should be, read in conjunction with the consolidated financial statements and the Notes thereto included in Cadence’s Annual Report on Form 10-K for the fiscal year ended December 29, 2018 . The unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q reflect all adjustments (which include only normal, recurring adjustments and those items discussed in these Notes) that are, in the opinion of management, necessary to state fairly the results of operations, cash flows and financial position for the periods and dates presented. The results for such periods are not necessarily indicative of the results to be expected for the full fiscal year. Certain prior period balances have been reclassified to conform to the current year presentation. Management has evaluated subsequent events through the issuance date of the unaudited condensed consolidated financial statements. Use of Estimates Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Comparability Effective the first day of fiscal 2019, Cadence adopted multiple new accounting standards. Prior periods were not retrospectively restated, so the condensed consolidated balance sheet as of September 28, 2019 was prepared using accounting standards that were different than those in effect as of December 29, 2018 . Therefore, the condensed consolidated balance sheets as of September 28, 2019 and December 29, 2018 are not directly comparable. 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 assets and lease liabilities on the balance sheet. The most prominent of the changes in the standard is the recognition of right-of-use (“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 us 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 condensed consolidated financial statements for arrangements in which Cadence is the lessor. For additional information regarding Cadence’s leases, see Note 6 in the notes to condensed 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 condensed consolidated financial statements.

Debt Disclosure [Abstract]
DEBT	DEBT Cadence’s outstanding debt as of September 28, 2019 and December 29, 2018 was as follows: September 28, 2019 December 29, 2018 (In thousands) Principal Unamortized Discount Carrying Value Principal Unamortized Discount Carrying Value Revolving Credit Facility $ — $ — $ — $ 100,000 $ — $ 100,000 2024 Notes 350,000 (4,167 ) 345,833 350,000 (4,709 ) 345,291 Total outstanding debt $ 350,000 $ (4,167 ) $ 345,833 $ 450,000 $ (4,709 ) $ 445,291 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 1.25% 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 September 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 $376.8 million as of September 28, 2019 . 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 from Contract with Customer [Abstract]
REVENUE	REVENUE Cadence combines 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 the three and nine months ended September 28, 2019 and September 29, 2018 : Three Months Ended Nine Months Ended September 28, September 29, September 28, September 29, Functional Verification, including Emulation and Prototyping Hardware 1 20 % 22 % 22 % 24 % Digital IC Design and Signoff 30 % 30 % 30 % 29 % Custom IC Design and Simulation 26 % 26 % 26 % 26 % System Interconnect and Analysis 9 % 9 % 9 % 9 % IP 15 % 13 % 13 % 12 % Total 100 % 100 % 100 % 100 % _____________ 1 Includes immaterial amount of revenue accounted for under Topic 842. Revenue by product group 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 groups 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. Judgment is required to determine the standalone selling price (“SSP”) for each distinct performance obligation. Cadence rarely licenses or sells products on a standalone basis, so Cadence is required to estimate the SSP for each performance obligation. 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 condensed 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 condensed consolidated balance sheet and primarily relate to Cadence’s rights to consideration for work completed but not billed as of September 28, 2019 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 September 28, 2019 and December 29, 2018 were as follows: As of September 28, December 29, (In thousands) Contract assets $ 8,513 $ 10,055 Deferred revenue 392,136 401,174 Cadence recognized revenue of $44.4 million and $290.4 million during the three and nine months ended September 28, 2019 , and $39.9 million and $250.2 million during the three and nine months ended September 29, 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. 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. 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 $3.0 billion as of September 28, 2019 , which includes $212.1 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. Cadence expects to recognize approximately 60% of the revenue included in the contracted but unsatisfied performance obligations, excluding non-cancellable IPAA commitments, over the next 12 months and the remainder thereafter. Cadence recognized revenue of $10.0 million and $26.7 million during the three and nine months ended September 28, 2019 , and $10.8 million and $25.3 million during the three and nine months ended September 29, 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.

Leases

Leases [Abstract]
Leases [Text Block]	LEASES Lessee Considerations Under Topic 842, operating lease expense is generally recognized evenly over the term of the lease. 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. Certain leases include rental payments that are adjusted periodically based on changes in consumer price and other indices. 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. Activity related to Cadence’s leases was as follows: Three Months Ended Nine Months Ended September 28, September 28, (In thousands) Operating lease expense $ 8,409 $ 25,728 Cash paid for amounts included in the measurement of operating lease liabilities 8,174 22,416 ROU assets obtained in exchange for operating lease obligations 3,437 37,032 Cadence’s lease agreements generally 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. Cadence used the incremental borrowing rate on December 29, 2018 for all leases that commenced prior to that date. ROU lease assets and lease liabilities for Cadence’s operating leases were recorded in the condensed consolidated balance sheet as follows: As of September 28, 2019 (In thousands) Other assets $ 104,518 Accounts payable and accrued liabilities $ 27,717 Other long-term liabilities 90,506 Total lease liabilities $ 118,223 Weighted average remaining lease term (in years) 5.2 Weighted average discount rate 4.4 % Future lease payments included in the measurement of lease liabilities on the condensed consolidated balance sheet as of September 28, 2019 , for the following five fiscal years and thereafter were as follows: Operating Leases (In thousands) 2019 – remaining period $ 7,524 2020 31,960 2021 28,517 2022 20,680 2023 15,254 Thereafter 29,942 Total future lease payments 133,877 Less imputed interest (15,654 ) Total $ 118,223 As of December 29, 2018 , future minimum lease payments, as defined under the previous lease accounting guidance of ASC Topic 840, under non-cancelable operating leases for the following five fiscal years and thereafter were as follows: Operating Leases (In thousands) 2019 $ 26,252 2020 23,130 2021 19,778 2022 14,243 2023 11,510 Thereafter 17,100 Total lease payments $ 112,013 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 four 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 to four years and are classified as sales-type leases with revenue and cost of sales recognized upon delivery.

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 2 in the notes to condensed 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 the nine months ended September 28, 2019 . 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 September 28, 2019 and December 29, 2018 : Fair Value Measurements as of September 28, 2019 Total Level 1 Level 2 Level 3 (In thousands) Assets Cash equivalents: Money market funds $ 351,712 $ 351,712 $ — $ — Marketable equity securities 3,773 3,773 — — Securities held in Non-Qualified Deferred Compensation (“NQDC”) trust 31,196 31,196 — — Total Assets $ 386,681 $ 386,681 $ — $ — Total Level 1 Level 2 Level 3 (In thousands) Liabilities Foreign currency exchange contracts $ 2,075 $ — $ 2,075 $ — Total Liabilities $ 2,075 $ — $ 2,075 $ — Fair Value Measurements as of December 29, 2018 Total Level 1 Level 2 Level 3 (In thousands) Assets Cash equivalents: Money market funds $ 327,841 $ 327,841 $ — $ — Marketable equity securities 3,887 3,887 — — Securities held in NQDC trust 27,767 27,767 — — Foreign currency exchange contracts 101 — 101 — Total Assets $ 359,596 $ 359,495 $ 101 $ — As of December 29, 2018, Cadence did not have any financial liabilities requiring a recurring fair value measurement.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES 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 its hardware products, generally for a 90 -day period. Cadence did not incur any significant costs related to warranty obligations during the three and nine months ended September 28, 2019 and September 29, 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 the three and nine months ended September 28, 2019 and September 29, 2018 .

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.

Subsequent Events [Abstract]
SUBSEQUENT EVENT	SUBSEQUENT EVENT In October 2019, Cadence initiated a series of transactions involving an internal realignment of its international operating structure. Cadence expects that this realignment may significantly increase its foreign deferred tax assets. Cadence has not completed its analysis and is currently unable to estimate the impact to its consolidated financial statements or the related disclosures. Cadence expects to complete its analysis and record the impact to the consolidated financial statements during the fourth quarter of fiscal 2019.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of estimates	Use of Estimates Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Comparability	Comparability Effective the first day of fiscal 2019, Cadence adopted multiple new accounting standards. Prior periods were not retrospectively restated, so the condensed consolidated balance sheet as of September 28, 2019 was prepared using accounting standards that were different than those in effect as of December 29, 2018 . Therefore, the condensed consolidated balance sheets as of September 28, 2019 and December 29, 2018 are not directly comparable.
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 assets and lease liabilities on the balance sheet. The most prominent of the changes in the standard is the recognition of right-of-use (“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 us 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 condensed consolidated financial statements for arrangements in which Cadence is the lessor. For additional information regarding Cadence’s leases, see Note 6 in the notes to condensed 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 condensed consolidated financial statements.
Leases of lessee	Leases with an initial term of twelve months or less are not recorded on the balance sheet.
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 2 in the notes to condensed 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 the nine months ended September 28, 2019 .
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.
