Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies We have prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Pursuant to these rules and regulations, we have condensed or omitted certain information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). In management’s opinion, we have made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary to fairly present our unaudited condensed consolidated balance sheets, results of operations, comprehensive income, stockholders’ equity and cash flows. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended October 31, 2021 as filed with the SEC on December 13, 2021 (our Annual Report). Use of Estimates. To prepare financial statements in conformity with U.S. GAAP, management must make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates and may result in material effects on our operating results and financial position. Principles of Consolidation. The unaudited condensed consolidated financial statements include our accounts and the accounts of our subsidiaries. All intercompany accounts and transactions have been eliminated. Fiscal Year End. Our fiscal year generally ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that approximately every five years, we have a 53-week year. When a 53-week year occurs, we include the additional week in the first quarter to realign fiscal quarters with calendar quarters. Fiscal 2022 and 2021 are both 52-week years. Fiscal 2022 will end on October 29, 2022. Fiscal 2021 ended on October 30, 2021. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end. Significant Accounting Policies. There have been no material changes to our significant accounting policies included in our Annual Report, other than our accounting policy for redeemable non-controlling interest . Redeemable Non-controlling Interest. Non-controlling interest that is not solely redeemable within our control is reported as the temporary equity in our unaudited condensed consolidated balance sheets. The carrying value of the redeemable non-controlling interest equals the redemption value at the end of each reporting period, after giving effect to the change from the net income (loss) attributable to the redeemable non-controlling interest. We adjust the redemption value of the non-controlling interest on a quarterly basis and changes in the estimated redemption value are recorded with corresponding adjustments against retained earnings. Recently Adopted Accounting Pronouncements In December 2019, FASB issued Accounting Standards Update (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. We adopted the standard as of the beginning of fiscal 2022 on a prospective basis and the adoption of this standard did not have a material impact on our unaudited condensed consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The new guidance requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers, as if the acquirer had originated the contracts. We early adopted the standard in the second quarter of fiscal 2022 and the adoption had no material retrospective impact on our unaudited condensed consolidated financial statements for acquisitions completed in fiscal 2022. Any future impact will be dependent on the facts and circumstances of future acquisitions.

Business Combinations [Abstract]
Business Combinations	Business Combinations During the three months ended January 31, 2022, we completed an acquisition for purchase consideration of $20.0 million, net of cash acquired. The preliminary purchase price allocations were $4.3 million of identifiable intangible assets and $15.7 million of goodwill, which were attributable to the Semiconductor & System Design reporting segment. There was no tax deductible goodwill related to the acquisition. Acquisition of Equity Interest in OpenLight Photonics, Inc. (OpenLight) During the three months ended April 30, 2022, we acquired 75% equity interest in OpenLight for $90.0 million in cash consideration. The remaining 25% equity interest in OpenLight is held by Juniper Networks, Inc. (the Minority Investor) from their contribution of IP and certain tangible assets. The preliminary purchase price allocations were $94.0 million of identifiable intangible assets and $45.1 million of goodwill, which were attributable to the Semiconductor & System Design reporting segment. The goodwill was mainly attributable to the assembled workforce and planned growth in new markets. There was no tax deductible goodwill related to the acquisition. The agreement with the Minority Investor contains redemption features whereby the interest held by the Minority Investor is redeemable either (i) at the option of the Minority Investor on or after the third anniversary of the acquisition or sooner in certain circumstances or (ii) at our option beginning on the third anniversary of the acquisition. This option is exercisable at the greater of fair value at the time of redemption or $30.0 million and was valued at $10.1 million, resulting in a total consideration of $100.1 million. As of April 30, 2022, the carrying amount of the redeemable non-controlling interest was recorded at its estimated fair value of $43.5 million in the unaudited condensed consolidated balance sheet. We have included the financial results of these acquisitions in our unaudited condensed consolidated financial statements from the date of acquisition. We do not consider these acquisitions to be material, individually or in the aggregate, to our unaudited condensed consolidated financial statements. Preliminary Fair Value Estimates The preliminary fair value estimates for the assets acquired and liabilities assumed for all acquisitions completed within 12 months from the applicable acquisition date are not yet finalized and may change as additional information becomes available during the respective measurement periods. The primary areas of those preliminary estimates relate to certain tangible assets and liabilities, identifiable intangible assets, and income taxes. Acquisition-Related Transaction Costs Transaction costs were $4.0 million and $6.1 million during the three and six months ended April 30, 2022, respectively. Transaction costs were $2.3 million and $5.9 million during the three and six months ended April 30, 2021, respectively. These costs mainly consisted of professional fees and administrative costs and were expensed as incurred in our unaudited condensed consolidated statements of income.

There were no impairments of non-marketable equity securities during the three and six months ended April 30, 2022. There were no impairments of non-marketable equity securities during the three and six months ended April 30, 2021. Derivatives We recognize derivative instruments as either assets or liabilities in the unaudited condensed consolidated balance sheets at fair value and provide qualitative and quantitative disclosures about such derivatives. We operate internationally and are exposed to potentially adverse movements in foreign currency exchange rates. We enter into hedges in the form of foreign currency forward contracts to reduce our exposure to foreign currency rate changes on non-functional currency denominated forecasted transactions and balance sheet positions including: (1) certain assets and liabilities, (2) shipments forecasted to occur within approximately one month, (3) future billings and revenue on previously shipped orders, and (4) certain future intercompany invoices denominated in foreign currencies. The duration of forward contracts ranges from approximately one month to 25 months, the majority of which are short-term. We do not use foreign currency forward contracts for speculative or trading purposes. We enter into foreign exchange forward contracts with high credit quality financial institutions that are rated "A" or above and to date have not experienced nonperformance by counterparties. In addition, we mitigate credit risk in derivative transactions by permitting net settlement of transactions with the same counterparty and anticipate continued performance by all counterparties to such agreements. The assets or liabilities associated with the forward contracts are recorded at fair value in other current assets or accrued liabilities in the unaudited condensed consolidated balance sheets. The accounting for gains and losses resulting from changes in fair value depends on the use of the foreign currency forward contract and whether it is designated and qualifies for hedge accounting. The cash flow impact upon settlement of the derivative contracts will be included in net cash provided by operating activities in the unaudited condensed consolidated statements of cash flows. Cash Flow Hedging Activities Certain foreign exchange forward contracts are designated and qualify as cash flow hedges. These contracts have durations of approximately 25 months or less. Certain forward contracts are rolled over periodically to capture the full length of exposure to our foreign currency risk, which can be up to three years. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedge, and the hedges must be highly effective in offsetting changes to future cash flows on the hedged transactions. The related gains or losses resulting from changes in fair value of these hedges is initially reported, net of tax, as a component of other comprehensive income (loss) (OCI) in stockholders’ equity and reclassified into revenue or operating expenses, as appropriate, at the time the hedged transactions affect earnings. We expect a majority of the hedge balance in OCI to be reclassified to the statements of income within the next 12 months. We did not record any gains or losses related to discontinuation of cash flow hedges during the six months ended April 30, 2022 and 2021. Non-designated Hedging Activities Our foreign exchange forward contracts that are used to hedge non-functional currency denominated balance sheet assets and liabilities are not designated as hedging instruments. Accordingly, any gains or losses from changes in the fair value of the forward contracts are recorded in other income (expense), net. The gains and losses on these forward contracts generally offset the gains and losses associated with the underlying assets and liabilities, which are also recorded in other income (expense), net. The duration of the forward contracts for hedging our balance sheet exposure is approximately one month. We also have certain foreign exchange forward contracts for hedging certain international revenues and expenses that are not designated as hedging instruments. Accordingly, any gains or losses from changes in the fair value of the forward contracts are recorded in other income (expense), net. The gains and losses on these forward contracts generally offset the gains and losses associated with the foreign currency in operating income. The duration of these forward contracts is usually less than one year. The overall goal of our hedging program is to minimize the impact of currency fluctuations on the net income over the fiscal year. The effects of the non-designated derivative instruments on our unaudited condensed consolidated statements of income were summarized as follows: Three Months Ended Six Months Ended 2022 2021 2022 2021 (in thousands) Gains (losses) recorded in other income (expense), net $ (5,707) $ 1,128 $ (5,261) $ 2,257 The notional amounts in the table below for derivative instruments provided one measure of the transaction volume outstanding: As of April 30, 2022 October 31, 2021 (in thousands) Total gross notional amounts $ 1,290,445 $ 1,176,152 Net fair value $ 6,580 $ 13,404 Our exposure to the market gains or losses will vary over time as a function of currency exchange rates. The amounts ultimately realized upon settlement of these financial instruments, together with the gains and losses on the underlying exposures, will depend on actual market conditions during the remaining life of the instruments.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC 820-10, Fair Value Measurements and Disclosures, defines fair value, establishes guidelines and enhances disclosure requirements for fair value measurements. The accounting guidance requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The accounting guidance also establishes a fair value hierarchy based on the independence of the source and objective evidence of the inputs used. There are three fair value hierarchies based upon the level of inputs that are significant to fair value measurement: Level 1 —Observable inputs that reflect quoted prices (unadjusted) for identical instruments in active markets; Level 2 —Observable inputs other than quoted prices included in Level 1 for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-driven valuations in which all significant inputs and significant value drivers are observable in active markets; and Level 3 —Unobservable inputs to the valuation derived from fair valuation techniques in which one or more significant inputs or significant value drivers are unobservable. On a recurring basis, we measure the fair value of certain of our assets and liabilities, which include cash equivalents, non-qualified deferred compensation plan assets, and foreign currency derivative contracts. Our cash equivalents and short-term investments are classified within Level 1 or Level 2 because they are valued using quoted market prices in an active market or alternative independent pricing sources and models utilizing market observable inputs. Our non-qualified deferred compensation plan assets consist of money market and mutual funds invested in domestic and international marketable securities that are directly observable in active markets and are therefore classified within Level 1. Our foreign currency derivative contracts are classified within Level 2 because these contracts are not actively traded, and the valuation inputs are based on quoted prices and market observable data of similar instruments. Our borrowings under the credit and term loan facilities are classified within Level 2 because these borrowings are not actively traded and have a variable interest rate structure based upon market rates currently available for our debt with similar terms and maturities. See Note 10. Credit and Term Loan Facilities for more information on these borrowings.

Debt Disclosure [Abstract]
Credit and Term Loan Facilities	Credit and Term Loan Facilities On January 22, 2021, we entered into a Fourth Extension and Amendment Agreement (the Fourth Amendment), which amended and restated our previous credit agreement, dated as of November 28, 2016 (as amended and restated, the Credit Agreement). Our outstanding borrowings under the previous credit agreement, which as of January 22, 2021 consisted of term loans in the aggregate principal amount of $97.5 million, were carried over under the Credit Agreement and fully repaid on November 26, 2021. The Fourth Amendment extended the termination date of the existing $650.0 million senior unsecured revolving credit facility (the Revolver) from November 28, 2021 to January 22, 2024, which could be further extended at our option. The Credit Agreement also provides an uncommitted incremental loan facility of up to $150 million in the aggregate principal amount. The Credit Agreement contains financial covenants requiring us to maintain a maximum consolidated leverage ratio and a minimum consolidated interest coverage ratio, as well as other non-financial covenants. As of April 30, 2022, we were in compliance with all financial covenants. There was no outstanding balance under the Revolver as of April 30, 2022 and October 31, 2021. We expect our borrowings, if any, under the Revolver will fluctuate from quarter to quarter. Borrowings bear interest at a floating rate based on a margin over our choice of market observable base rates as defined in the Credit Agreement. As of April 30, 2022, Revolver bore interest at LIBOR +1.000%. In addition, commitment fees are payable on the Revolver at rates between 0.125% and 0.200% per year based on our leverage ratio on the daily amount of the revolving commitment. In July 2018, we entered into a 12-year 220.0 million Renminbi (approximately $33.0 million) credit agreement with a lender in China to support our facilities expansion. Borrowings bear interest at a floating rate based on the 5 year Loan Prime Rate plus 0.74%. As of April 30, 2022, we had $23.8 million outstanding balance under the agreement.

These leases have various expiration dates through December 31, 2040, some of which include options to extend the leases for up to 10 years. Because we are not reasonably certain to exercise these renewal options, the options are not considered in determining the lease term and associated potential option payments are excluded from lease payments. The components of our lease expense during the period presented were as follows: Three Months Ended April 30, Six Months Ended April 30, 2022 2021 2022 2021 (in thousands) Operating lease expense (1) $ 22,159 $ 23,349 $ 44,191 $ 46,975 Variable lease expense (2) 2,870 1,842 4,993 3,177 Total lease expense $ 25,029 $ 25,191 $ 49,184 $ 50,152 (1) Operating lease expense includes immaterial amounts of short-term leases, net of sublease income.

Stock Repurchase Program [Abstract]
Stock Repurchase Program	Stock Repurchase Program Our Board of Directors (the Board) approved a stock repurchase program (the Program) with authorization to purchase up to $1.0 billion of our common stock in December 2021. As of April 30, 2022, $500.0 million remained available for future repurchases under the Program. In February 2022, we entered into an accelerated stock repurchase agreement (the February 2022 ASR) to repurchase an aggregate of $200.0 million of our common stock. Pursuant to the February 2022 ASR, we made a prepayment of $200.0 million to receive initial deliveries of shares valued at $160.0 million. The remaining balance of $40.0 million was settled in April 2022. Total shares purchased under the February 2022 ASR were approximately 0.7 million shares, at an average purchase price of $305.36 per share. During the three months ended April 30, 2022 , we also repurchased on the open market approximately 0.2 million shares of our common stock at an average price of $298.29 per share for an aggregate purchase price of $50.0 million. Stock repurchase activities as well as the reissuance of treasury stock for employee stock-based compensation purposes were as follows: Three Months Ended Six Months Ended 2022 (1) 2021 (2) 2022 2021 (in thousands) Total shares repurchased 984 756 1,685 1,593 Total cost of the repurchased shares $ 290,000 $ 195,211 $ 535,000 $ 398,082 Reissuance of treasury stock 683 946 1,578 1,529 (1) Included the 161,215 shares and $40.0 million equity forward contract from the December 2021 ASR settled in February 2022.

Under the award agreements, the vesting of the market-based RSUs is contingent on achieving total stockholder return (TSR) relative to a peer index as well as revenue growth metrics. The performance period during which the achievement goals will be measured is fiscal 2022 and fiscal 2023. The maximum potential awards that may be earned are 187.5% of the target number of the initial a wards. The awards will vest in equal increments in December 2023 and December 2024 if the TSR target, revenue growth metrics, and service conditions are achieved. The grant date fair value for the market-based RSUs of $280.82 was determined using a Monte Carlo simulation model with the following assumptions: expected volatility of 33.01%, risk-free interest rate of 1.33% and an expected term of 1.69 years. As of April 30, 2022, we had $937.6 million of total unrecognized stock-based compensation expense relating to options, RSUs and restricted stock awards, which is expected to be recognized over a weighted-average period of 2.3 years. As of April 30, 2022, we had $76.3 million of unrecognized stock-based compensation expense relating to our Employee Stock Purchase Plan (ESPP), which is expected to be recognized over a period of approximately 2.0 years.

Segment Reporting [Abstract]
Segment Disclosure	Segment Disclosure Segment reporting is based upon the “management approach,” i.e., how management organizes our operating segments for which separate financial information is (1) available and (2) evaluated regularly by the Chief Operating Decision Makers (CODMs) in deciding how to allocate resources and in assessing performance. The CODMs were our two Co-Chief Executive Officers. One of our Co-Chief Executive Officers transitioned out of this role effective May 1, 2022. Starting with the third quarter of fiscal 2022, our CODM will be our Chief Executive Officer. We have two reportable segments: (1) Semiconductor & System Design, which includes EDA tools, IP products, system integration solutions and other associated revenue categories, and (2) Software Integrity, which includes a comprehensive solution for building integrity—security, quality and compliance testing—into the customers’ software development lifecycle and supply chain. The financial information provided to and used by the CODMs to assist in making operational decisions, allocating resources, and assessing performance reflects consolidated financial information as well as revenue, adjusted operating income, and adjusted operating margin information for the Semiconductor & System Design and Software Integrity segments, accompanied by disaggregated information relating to revenue by geographic region. Information by reportable segment was as follows: Three Months Ended Six Months Ended 2022 2021 2022 2021 (in thousands) Total Segments: Revenue $ 1,279,229 $ 1,024,323 $ 2,549,484 $ 1,994,644 Adjusted operating income 470,153 317,240 929,544 604,060 Adjusted operating margin 37 % 31 % 36 % 30 % Semiconductor & System Design: Revenue $ 1,166,377 $ 930,427 $ 2,329,071 $ 1,808,795 Adjusted operating income 457,128 308,816 904,520 587,692 Adjusted operating margin 39 % 33 % 39 % 32 % Software Integrity: Revenue $ 112,852 $ 93,896 $ 220,413 $ 185,849 Adjusted operating income 13,025 8,424 25,024 16,368 Adjusted operating margin 12 % 9 % 11 % 9 % Certain operating expenses are not allocated to the segments and are managed at a consolidated level.

As a result, total assets by segment are not required to be disclosed. In allocating revenue to particular geographic areas, the CODMs consider where individual “seats” or licenses to our products are located. Revenue is defined as revenue from external customers.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Effective Tax Rate We estimate our annual effective tax rate at the end of each fiscal quarter. The effective tax rate takes into account our estimations of annual pre-tax income, the geographic mix of pre-tax income and interpretations of tax laws and possible outcomes of audits. The following table presented the provision for income taxes and the effective tax rates: Three Months Ended Six Months Ended 2022 2021 2022 2021 (in thousands) Income before income taxes $ 339,788 $ 215,995 $ 667,031 $ 393,099 Provision for income taxes $ 45,896 $ 21,193 $ 59,798 $ 36,269 Effective tax rate 13.5 % 9.8 % 9.0 % 9.2 % Our effective tax rate for the six months ended April 30, 2022 is lower than the statutory federal corporate tax rate of 21.0% primarily due to U.S. federal research tax credits, foreign-derived intangible income deduction, excess tax benefits from stock-based compensation, and U.S. foreign tax credits, partially offset by state taxes, the effect of non-deductible stock-based compensation, and higher taxes on certain foreign earnings. Our effective tax rate increased in the three months ended April 30, 2022 as compared to the same period in fiscal 2021, primarily due to less excess tax benefits from stock-based compensation. Our effective tax rate for the six months ended April 30, 2022 is consistent with the same period in fiscal 2021. The timing of the resolution of income tax examinations, and the amounts and timing of various tax payments that are part of the settlement process, are highly uncertain. Variations in such amounts and/or timing could cause large fluctuations in the balance sheet classification of current and non-current assets and liabilities. We believe that in the coming 12 months, it is reasonably possible that either certain audits and ongoing tax litigation will conclude or the statute of limitations on certain state and foreign income and withholding taxes will expire, or both. Given the uncertainty as to ultimate settlement terms, the timing of payment and the impact of such settlements on other uncertain tax positions, the range of the estimated potential decrease in underlying unrecognized tax benefits is between $0 and $40 million. Non-U.S. Examinations Hungarian Tax Authority In 2017, the Hungarian Tax Authority (the HTA) assessed withholding taxes of approximately $25.0 million and interest and penalties of $11.0 million, against our Hungary subsidiary (Synopsys Hungary). Synopsys Hungary contested the assessment with the Hungarian Administrative Court (Administrative Court). As required under Hungarian law, Synopsys Hungary paid the assessment and recorded a tax expense due to an unrecognized tax benefit of $17.4 million, which is net of estimated U.S. foreign tax credits. The Administrative Court found against Synopsys Hungary, and we appealed to the Hungarian Supreme Court. During 2021, the Hungarian Supreme Court heard our appeal and remanded the case to the Administrative Court for further proceedings. The Administrative Court once again ruled against Synopsys Hungary and we filed another appeal with the Hungarian Supreme Court. The Hungarian Supreme Court heard our appeal on January 27, 2022, vacated the lower court's decision and remanded the case back to the Administrative Court for further proceedings. On March 10, 2022, we received the written opinion from the Hungarian Supreme Court and submitted a brief with the Hungarian Administrative Court on May 4, 2022. Our next hearing with the Administrative Court is scheduled for June 30, 2022. We are also under examination by the tax authorities in certain other jurisdictions. No material assessments have been proposed in these examinations.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Legal Proceedings We are subject to routine legal proceedings, as well as demands, claims and threatened litigation that arise in the normal course of our business. The ultimate outcome of any litigation is often uncertain and unfavorable outcomes could have a negative impact on our results of operations and financial condition. We regularly review the status of each significant matter and assesses our potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount is estimable, we accrue a liability for the estimated loss. Legal proceedings are inherently uncertain and, as circumstances change, it is possible that the amount of any accrued liability may increase, decrease or be eliminated. We have determined that, except as set forth below, no disclosure of estimated loss is required for a claim against us because: (1) there is not a reasonable possibility that a loss exceeding amounts already recognized (if any) may be incurred with respect to such claim; (2) a reasonably possible loss or range of loss cannot be estimated; or (3) such estimate is immaterial. Legal Settlement There have been no changes to the disclosure related to Mentor Graphics Corporation (now part of Siemens AG) since our Annual Report. See Note 9. Contingencies of the Annual Report for further information. Tax Matters We undergo examination from time to time by U.S. and foreign authorities for non-income based taxes, such as sales, use and value-added taxes, and are currently under examination by tax authorities in certain jurisdictions. If the potential loss from such examinations is considered probable and the amount or the range of loss could be estimated, we would accrue a liability for the estimated expense. In addition to the foregoing, we are, from time to time, party to various other claims and legal proceedings in the ordinary course of our business, including with tax and other governmental authorities. For a description of certain of these other matters, see Note 18. Income Taxes .

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates. To prepare financial statements in conformity with U.S. GAAP, management must make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates and may result in material effects on our operating results and financial position.
Principles of Consolidation	Principles of Consolidation. The unaudited condensed consolidated financial statements include our accounts and the accounts of our subsidiaries. All intercompany accounts and transactions have been eliminated.
Fiscal Year End	Fiscal Year End. Our fiscal year generally ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that approximately every five years, we have a 53-week year. When a 53-week year occurs, we include the additional week in the first quarter to realign fiscal quarters with calendar quarters. Fiscal 2022 and 2021 are both 52-week years. Fiscal 2022 will end on October 29, 2022. Fiscal 2021 ended on October 30, 2021. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.
Redeemable Non-controlling Interest	Redeemable Non-controlling Interest. Non-controlling interest that is not solely redeemable within our control is reported as the temporary equity in our unaudited condensed consolidated balance sheets. The carrying value of the redeemable non-controlling interest equals the redemption value at the end of each reporting period, after giving effect to the change from the net income (loss) attributable to the redeemable non-controlling interest. We adjust the redemption value of the non-controlling interest on a quarterly basis and changes in the estimated redemption value are recorded with corresponding adjustments against retained earnings.
Recently Adopted Accounting Pronouncements and Recent Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In December 2019, FASB issued Accounting Standards Update (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. We adopted the standard as of the beginning of fiscal 2022 on a prospective basis and the adoption of this standard did not have a material impact on our unaudited condensed consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The new guidance requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers, as if the acquirer had originated the contracts. We early adopted the standard in the second quarter of fiscal 2022 and the adoption had no material retrospective impact on our unaudited condensed consolidated financial statements for acquisitions completed in fiscal 2022. Any future impact will be dependent on the facts and circumstances of future acquisitions.

Under the award agreements, the vesting of the market-based RSUs is contingent on achieving total stockholder return (TSR) relative to a peer index as well as revenue growth metrics. The performance period during which the achievement goals will be measured is fiscal 2022 and fiscal 2023. The maximum potential awards that may be earned are 187.5% of the target number of the initial a wards. The awards will vest in equal increments in December 2023 and December 2024 if the TSR target, revenue growth metrics, and service conditions are achieved. The grant date fair value for the market-based RSUs of $280.82 was determined using a Monte Carlo simulation model with the following assumptions: expected volatility of 33.01%, risk-free interest rate of 1.33% and an expected term of 1.69 years.

[1]	(1) During the three and six months ended April 30, 2022, we recognized stock-based compensation expense relating to restricted stock units (RSUs), granted to senior executives in February 2022 with certain market, performance and service conditions (market-based RSUs). Under the award agreements, the vesting of the market-based RSUs is contingent on achieving total stockholder return (TSR) relative to a peer index as well as revenue growth metrics. The performance period during which the achievement goals will be measured is fiscal 2022 and fiscal 2023. The maximum potential awards that may be earned are 187.5% of the target number of the initial a wards. The awards will vest in equal increments in December 2023 and December 2024 if the TSR target, revenue growth metrics, and service conditions are achieved. The grant date fair value for the market-based RSUs of $280.82 was determined using a Monte Carlo simulation model with the following assumptions: expected volatility of 33.01%, risk-free interest rate of 1.33% and an expected term of 1.69 years.
