SYNOPSYS, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Description of Business

Synopsys, Inc. (Synopsys or the Company) provides products and services used across the entire silicon to software spectrum, from engineers creating advanced semiconductors to software developers seeking to ensure the security and quality of their code. The Company is a global leader in supplying the electronic design automation (EDA) software that engineers use to design and test integrated circuits (ICs), also known as chips. The Company also offers semiconductor intellectual property (IP) products, which are pre-designed circuits that engineers use as components of larger chip designs rather than designing those circuits themselves. The Company provides software and hardware used to validate the electronic systems that incorporate chips and the software that runs on them. To complement these offerings, the Company provides technical services and support to help its customers develop advanced chips and electronic systems. These products and services are part of the Company’s Semiconductor & System Design segment.

The Company is also a leading provider of software tools and services that improve the security and quality of software code in a wide variety of industries, including electronics, financial services, media, automotive, medicine, energy and industrials. These tools and services are part of the Company’s Software Integrity segment.

Note 2. Summary of Significant Accounting Policies

The Company has 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, the Company has condensed or omitted certain information and footnote disclosures it normally includes in its annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). In management’s opinion, the Company has made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary to fairly present its unaudited condensed consolidated balance sheets, results of operations, comprehensive income, stockholders' equity and cash flows. The Company’s 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 Synopsys’ Annual Report on Form 10-K for the fiscal year ended October 31, 2019 as filed with the SEC on December 20, 2019.

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 the Company’s operating results and financial position. In addition, the Company has considered the potential impact of the COVID-19 pandemic on the business operations. Although no material impairment or other effects have been identified to date related to the COVID-19 pandemic, there is substantial uncertainty in the nature and degree of its continued effects over time. This uncertainty affects management’s accounting estimates and assumptions, which could result in greater variability in a variety of areas that depend on these estimates and assumptions as additional events and information are known.

Principles of Consolidation. The unaudited condensed consolidated financial statements include the accounts of the Company and all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Fiscal Year End. The Company’s fiscal year generally ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that approximately every five years, the Company has a 53-week year. When a 53-week year occurs, the Company includes the additional week in the first quarter to realign fiscal quarters with calendar quarters. Fiscal 2020 and 2019 are both 52-week years. Fiscal 2020 will end on October 31, 2020. Fiscal 2019 ended on November 2, 2019. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.

Leases. In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, "Leases (Topic 842)," which supersedes the previous lease requirements in Topic 840. Topic 842 was subsequently amended by several ASUs. The new guidance requires a lessee to recognize a right-of-use (ROU) asset and a lease liability for most operating leases in the consolidated balance sheets. These ASUs also made minor changes to lessor accounting and aligns key aspects of the lessor accounting model with the new

6

revenue recognition guidance. The new standard did not have a material impact on the unaudited condensed consolidated financial statements for arrangements in which the Company is the lessor.

The Company adopted Topic 842 at the beginning of fiscal 2020 using the modified retrospective method without restatement of comparative periods. The Company elected the package of practical expedients permitted under the transition guidance, which allows the carryforward of historical assessments about (1) lease classification, (2) whether a contract is or contains a lease, and (3) which costs qualify as initial direct costs for leases that existed prior to the adoption. The Company did not elect either the use of hindsight or land easements practical expedients available in transition.

The adoption of the standard did not have an impact on the Company’s beginning retained earnings, results of operations, or cash flows. The operating lease liabilities equaled the present value of the remaining Topic 840 minimum rental payments for those leases, discounted at the Company’s incremental borrowing rate as of the date of adoption. The ROU assets were measured at the amount of the related lease liabilities plus any prepaid rental payments and less any unamortized lease incentives such as tenant improvement allowances. The Company recognized ROU assets of $475 million and operating lease liabilities of $540 million on the unaudited condensed consolidated balance sheets.

After adoption, the Company determines if a contract is or contains a lease at inception. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make payments arising from the lease. Lease liabilities for operating and finance leases are recognized at the lease commencement date based on the present value of future lease payments over the remaining lease terms. ROU assets are derived from the carrying amount of the related lease liability plus any prepaid lease payments, less any lease incentives such as tenant improvement allowances. The Company primarily uses its incremental borrowing rate, determined as of the lease commencement date, to measure the present value of its future lease payments, as the rate implicit in the lease is generally not readily determinable. The Company uses a benchmark senior unsecured yield curve for debt instruments and considers specific credit quality, market conditions, tenor of lease arrangements, and quality of collateral to determine the incremental borrowing rate.

Operating lease expense is recognized on a straight-line basis over the lease term of each lease. Variable payments, such as for maintenance, property taxes or insurance, are recognized on our unaudited condensed consolidated statements of operations as incurred.

The Company has adopted both (1) the practical expedient to not separate lease from non-lease components and (2) the short-term lease exemption. The Company has elected the practical expedient to not separate lease from non-lease components for all classes of underlying assets and the short-term lease exemption for all classes of underlying assets except real estate leases, with terms 12 months or less.

Revenue Recognition. In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Codification (ASC 606), "Revenue from Contracts with Customers," which the Company adopted in fiscal 2019. See Note 2. Summary of Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended October 31, 2019 for revenue recognition policies under the new revenue guidance ASC 606.

Contract balances are as follows:

	As of
	April 30, 2020		October 31, 2019
	(in thousands)
Contract assets	$	193,651	$	210,557
Unbilled receivables	$	40,827	$	38,175
Deferred revenue	$	1,521,664	$	1,302,578

During the six months ended April 30, 2020, the Company recognized $795.9 million of revenue that was included in the deferred revenue balance as of October 31, 2019. During the six months ended April 30, 2019, the Company recognized $674.6 million of revenue that was included in the deferred revenue balance as of October 31, 2018.

Contracted but unsatisfied or partially unsatisfied performance obligations were approximately $4.7 billion as of April 30, 2020, which includes $652.6 million in non-cancellable Flexible Spending Account (FSA) commitments from customers where actual product selection and quantities of specific products or services are to be determined by customers at a later date. The Company has elected to exclude future sales-based royalty payments from the remaining performance obligations. The contracted but unsatisfied or partially unsatisfied performance obligations expected to be recognized over the next 12 months are approximately 57%, with the remainder recognized thereafter.

During the three and six months ended April 30, 2020, the Company recognized $34.2 million and $52.1 million, respectively, from performance obligations satisfied from sales-based royalties earned during the periods. During the three and six months ended April 30, 2019, the Company recognized $28.5 million and $47.3 million, respectively, from performance obligations satisfied from sales-based royalties earned during the periods.

Costs of Obtaining a Contract with Customer

The incremental costs of obtaining a contract with a customer, which consist primarily of direct sales commissions earned upon execution of the contract, are required to be capitalized under ASC 340-40 and amortized over the estimated period of which the benefit is expected to be received. As direct sales commissions paid for renewals are commensurate with the amounts paid for initial contracts, the deferred incremental costs will be recognized over the contract term. Total capitalized direct commission costs as of April 30, 2020 were $94.4 million and are included in other assets in the Company’s unaudited condensed consolidated balance sheets. Amortization of these assets was $14.5 million and $28.3 million during the three and six months ended April 30, 2020, respectively, and are included in sales and marketing expense in the Company’s unaudited condensed consolidated statements of operations. Amortization of these assets was $15.6 million and $28.4 million during the three and six months ended April 30, 2019, respectively, and are included in sales and marketing expense in the Company’s unaudited condensed consolidated statements of operations.

Note 4. Business Combinations

During the second quarter of fiscal 2020, the Company completed an acquisition for an aggregate consideration of $105.7 million; including cash consideration of $75.7 million and $30.0 million equal to the fair value of the Company’s products exchanged in connection with the acquisition.

The consideration of $105.7 million was preliminary allocated to $20.6 million of identifiable intangible assets, $4.2 million of net tangible assets, and $80.9 million in goodwill. The fair value of these intangible assets was estimated using the income method. These transactions are not considered to be material to the Company’s unaudited condensed consolidated statements of operations. The acquisition was attributable to the Semiconductor & System Design reporting segment.

Concurrent to this transaction, the Company executed a design service arrangement and recognized an asset of $10.7 million for the off-market component. The $10.7 million contract asset is expected to be amortized over the contractual period of the agreement of five years.

Other Fiscal 2020 Acquisitions

As of April 30, 2020, the Company completed several other acquisitions for an aggregate cash consideration of $79.8 million, net of cash acquired. The Company does not consider these acquisitions to be material, individually or in the aggregate, to the Company's unaudited condensed consolidated statements of operations. The preliminary purchase allocations are $25.2 million of identifiable intangible assets and $55.9 million in goodwill of which $12.9 million is attributable to the Software Integrity reporting segment. The fair value of these intangible assets and goodwill are estimated using the income method.

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.

Restricted cash. The Company includes amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the consolidated statements of cash flows. All restricted cash is primarily associated with office leases and has no material impact on the Company’s unaudited condensed consolidated statements of cash flows.

The following table provides a reconciliation of cash, cash equivalents and restricted cash included in the unaudited condensed consolidated balance sheets:

	As of
	April 30, 2020		October 31, 2019

Restricted cash included in Other long-term assets	725		756
Total cash, cash equivalents and restricted cash	$	858,418	$	730,527

Non-marketable equity securities. The Company’s strategic investment portfolio consists of non-marketable equity securities in privately held companies. The investments that the Company have less than 20% equity interests or do not have the ability to exercise significant influence are accounted using the measurement alternative when the fair value of the investment is not readily determinable. Securities accounted for as equity method investments are recorded at cost plus the proportional share of the issuers’ income or loss, which is recorded in the Company’s other income (expense), net. The cost basis of securities sold is based on the specific identification method. See Note 7. Fair Value Measures.

Derivatives

In the first quarter of 2020, the Company adopted ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedge Activities, which amends the hedge accounting recognition and presentation requirements of ASC 815. Pursuant to the provisions of ASU 2017-12, the Company is not required to separately measure and report hedge ineffectiveness, which was previously recorded in Other income (expense), net in our unaudited condensed consolidated statements of operations. Also, prior to the adoption of ASU 2017-12, the forward point components of the Cash Flow hedges were excluded from assessing effectiveness of the hedging relationship and were recorded on the unaudited condensed consolidated statements of operations in other income (expense), net. Upon adoption of ASU 2017-12, the Company presents the related earning impact of the Cash Flow hedges in the same income statement section as the hedged items. Also, adoption of the guidance did not impact opening retained earnings or have a material impact on our financial statements.

The Company recognizes derivative instruments as either assets or liabilities in the unaudited condensed consolidated balance sheets at fair value and provides qualitative and quantitative disclosures about such derivatives. The Company operates internationally and is exposed to potentially adverse movements in foreign currency exchange rates. The Company enters into hedges in the form of foreign currency forward contracts to reduce its exposure to foreign currency rate changes on non-functional currency denominated forecasted transactions and balance sheet positions 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.

11

The duration of forward contracts ranges from approximately one month to 22 months, the majority of which are short-term. The Company does not use foreign currency forward contracts for speculative or trading purposes. The Company enters into foreign exchange forward contracts with high credit quality financial institutions that are rated ‘A’ or above and to date has not experienced nonperformance by counterparties. In addition, the Company mitigates credit risk in derivative transactions by permitting net settlement of transactions with the same counterparty and anticipates 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 22 months or less. Certain forward contracts are rolled over periodically to capture the full length of exposure to the Company’s 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. The Company expects a majority of the hedge balance in OCI to be reclassified to the statements of operations within the next 12 months.

The Company did not have any gains or losses related to discontinuation of cash flow hedges during the three and six months ended April 30, 2020 and 2019.

Prior to adoption of ASU 2017-12, hedge effectiveness is evaluated monthly using spot rates, with any gain or loss caused by hedging ineffectiveness recorded in other income (expense), net. During the three and six months ended April 30, 2020 and 2019, the amounts recognized in other income (expense) for ineffectiveness and excluded component were immaterial.

Upon adoption of ASU 2017-12, the Company elected to use the forward method to measure hedge effectiveness for its Japanese yen revenue and foreign currency expense cash flow hedges. The Company did not change the process for its backlog cash flow hedges and continues to measure hedging effectiveness on a monthly basis.

Non-designated Hedging Activities

The Company’s 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 the Company’s balance sheet exposure is approximately one month.

The Company also has 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 the Company’s hedging program is to minimize the impact of currency fluctuations on its net income over its fiscal year.

12

The effects of the non-designated derivative instruments on the Company's unaudited condensed consolidated statements of operations is summarized as follows:

	Three Months Ended   April 30,					Six Months Ended   April 30,
	2020			2019		2020			2019
	(in thousands)
Gain (loss) recorded in other income (expense), net	$	(1,349	)	$	5,035	$	(1,104	)	$	3,135

The notional amounts in the table below for derivative instruments provide one measure of the transaction volume outstanding:

	(in thousands)
Total gross notional amount	$	896,477		$	817,441
Net fair value	$	(7,982	)	$	3,494

The Company’s exposure to market gain or loss 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.

The following table represents the unaudited condensed consolidated balance sheets location and amount of derivative instrument fair values segregated between designated and non-designated hedge instruments:

Note 7. Fair Value Measures

Accounting Standards Codification (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, the Company measures the fair value of certain of its assets and liabilities, which include cash equivalents, non-qualified deferred compensation plan assets, and foreign currency derivative contracts.

The Company’s cash equivalents 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.

The Company’s 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.

14

The Company’s 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.

The Company’s borrowings under its 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 to the Company for debt with similar terms and maturities. See Note 9. Credit and Term Loan Facilities for more information on these borrowings.

Assets/Liabilities Measured at Fair Value on a Non-Recurring Basis

Non-Marketable Equity Securities

Equity investments in privately-held companies, also called non-marketable equity securities, are accounted for using either the alternative method or equity method of accounting.

The non-marketable equity securities are measured and recorded at fair value when an event or circumstance which impacts the fair value of these securities indicates an other-than-temporary decline in value has occurred. In such events, these equity investments would be classified within Level 3 as they are valued using significant unobservable inputs or data in an inactive market, and the valuation requires management judgment due to the absence of market price and inherent lack of liquidity. The Company monitors these investments and generally uses the income approach to assess impairments based primarily on the financial conditions of these companies.

The Company did not recognize any impairment during the three months ended April 30, 2020 and recognized immaterial impairment during the six months ended April 30, 2020. The Company did not recognize any impairment during the three and six months ended April 30, 2019.

Note 8. Liabilities and Restructuring Charges

In the second quarter of fiscal 2019, the Company initiated a restructuring plan for involuntary and voluntary employee termination and facility closure actions as part of a business reorganization to better position the Company for future growth by reallocating resources to priority areas, and to a lesser extent, eliminating operational redundancy. The total charges under the 2019 restructuring plan were $86.0 million and consisted primarily of severance, termination, and retirement benefits under the 2019 Voluntary Retirement Program (VRP).

During the three and six months ended April 30, 2020, the Company incurred restructuring charges of approximately $29.7 million and $38.4 million, respectively, for involuntary employee termination actions and the VRP related to the 2019 restructuring plan. These charges consisted primarily of severance, termination, and retirement benefits. During the three and six months ended April 30, 2020, the Company made payments of $24.7 million and $30.7 million, respectively, related to the 2019 employee termination actions. As of April 30, 2020, $30.3 million remained outstanding and was recorded in accounts payable and accrued liabilities as payroll and related benefits in the unaudited condensed consolidated balance sheets. The remaining balance will be paid in fiscal 2020.

During the three and six months ended April 30, 2019, the Company incurred restructuring charges of approximately $14.7 million for involuntary employee termination actions.

Note 9. Credit and Term Loan Facilities

On November 28, 2016, the Company entered into an amended and restated credit agreement with several lenders (the Credit Agreement) providing for (i) a $650.0 million senior unsecured revolving credit facility (the Revolver) and (ii) a $150.0 million senior unsecured term loan facility (the Term Loan). The Credit Agreement amended and restated the Company’s previous credit agreement dated May 19, 2015, in order to increase the size of the revolving credit facility from $500.0 million to $650.0 million, provide a new $150.0 million senior unsecured term loan facility, and extend the termination date of the revolving credit facility from May 19, 2020 to November 28, 2021. Subject to obtaining additional commitments from lenders, the principal amount of the loans provided under the Credit Agreement may be increased by the Company by up to an additional $150.0 million. The Credit Agreement contains financial covenants requiring the Company to operate within a maximum leverage ratio and maintain a minimum interest coverage ratio, as well as other non-financial covenants. As of April 30, 2020, the Company was in compliance with all financial covenants.

As of April 30, 2020, the Company had $111.4 million outstanding balance, net of debt issuance costs, under the Term Loan, of which $90.0 million was classified as long-term liabilities. Outstanding principal payments under the Term Loan are due as follows:

Fiscal year	(in thousands)
Remainder of fiscal 2020	$	9,376
2021	27,187
2022	75,000
Total	$	111,563

In July 2018, the Company entered into a 220.0 million RMB (approximately $33.0 million) credit agreement with a lender in China to support its facilities expansion. Borrowings bear interest at a floating rate based on the Chinese Central Bank rate plus 10% of such rate. As of April 30, 2020, the Company had $24.4 million outstanding under the agreement.

As of October 31, 2019, the Company had $119.8 million outstanding balance, net of debt issuance costs, under the Term Loan, of which $102.2 million was classified as long-term liabilities. There was no outstanding balance under the Revolver as of October 31, 2019.

There was $100.0 million outstanding balance under the Revolver as of April 30, 2020. The Company expects its borrowings under the Revolver will fluctuate from quarter to quarter. Borrowings bear interest at a floating rate based on a margin over the Company’s choice of market observable base rates as defined in the Credit Agreement. As of April 30, 2020, borrowings under the Term Loan bore interest at LIBOR +1.125% and the applicable interest rate for the Revolver was LIBOR +1.000%. In addition, commitment fees are payable on the Revolver at rates between 0.125% and 0.200% per year based on the Company’s leverage ratio on the daily amount of the revolving commitment.

The carrying amount of the short-term and long-term debt approximates the estimated fair value. These borrowings under the Credit Agreement have a variable interest rate structure and are classified within Level 2 of the fair value hierarchy.

Note 12. Stock Repurchase Program

The Company’s Board of Directors (the Board) previously approved a stock repurchase program pursuant to which the Company was authorized to purchase up to $500.0 million of its common stock, and has periodically replenished the stock repurchase program to such amount. The Board replenished the stock repurchase program up to $500.0 million on June 14, 2019. The program does not obligate the Company to acquire any particular amount of common stock, and the program may be suspended or terminated at any time by the Company's Chief Financial Officer or the Board. The Company repurchases shares to offset dilution caused by ongoing stock issuances from existing equity plans for equity compensation awards and issuances related to acquisitions, and when management believes it is a good use of cash. Repurchases are transacted in accordance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended (the Exchange Act) and may be made through any means, including, but not limited to, open market purchases, plans executed under Rule 10b5-1(c) of the Exchange Act and

19

structured transactions. As of April 30, 2020, $200.0 million remained available for future repurchases under the program.

In December 2019, the Company entered into an accelerated share repurchase agreement (the December 2019 ASR) to repurchase an aggregate of $100.0 million of the Company's common stock. Pursuant to the December 2019 ASR, the Company made a prepayment of $100.0 million to receive initial share deliveries of shares valued at $80.0 million. The remaining balance of $20.0 million was settled in February 2020. Total shares purchased under the December 2019 ASR were approximately 0.7 million shares, at an average purchase price of $149.75 per share.

In February 2020, the Company entered into an accelerated share repurchase agreement (the February 2020 ASR) to repurchase an aggregate of $100.0 million of the Company's common stock. Pursuant to the February 2020 ASR, the Company made a prepayment of $100.0 million to receive initial share deliveries of shares valued at $80.0 million. The remaining balance of $20.0 million was settled in May 2020. Total shares purchased under the February 2020 ASR were approximately 0.7 million shares, at an average purchase price of $140.41 per share.

Intrinsic value of awards exercised	$	77,912	$	50,426	$	102,311	$	58,578

Note 14. Net Income Per Share

The Company computes basic net income per share by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted net income per share reflects the dilution from potential common shares outstanding such as stock options and unvested restricted stock units and awards during the period using the treasury stock method.

The table below reconciles the weighted average common shares used to calculate basic net income per share with the weighted average common shares used to calculate diluted net income per share:

	Three Months Ended   April 30,				Six Months Ended   April 30,

⁽¹⁾  These stock options and unvested restricted stock units were anti-dilutive for the respective periods and are excluded in calculating diluted net income per share. While such awards were anti-dilutive for the respective periods, they could be dilutive in the future.

Note 15. Segment Disclosure

Segment reporting is based upon the “management approach,” i.e., how management organizes the Company’s 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. Synopsys’ CODMs are its two Co-Chief Executive Officers.

The Company has 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.

21

Information by reportable segment was as follows:

	Three Months Ended   April 30,						Six Months Ended   April 30,

Certain operating expenses are not allocated to the segments and are managed at a consolidated level. The unallocated expenses managed at a consolidated level, including amortization of intangible assets, stock compensation and other operating expenses, are presented in the table below to provide a reconciliation of the total adjusted operating income from segments to the Company's consolidated operating income:

	Three Months Ended   April 30,						Six Months Ended   April 30,

Total operating income	$	125,895		$	115,502		$	213,411		$	262,916

The CODMs do not use total assets by segment to evaluate segment performance or allocate resources. 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 the Company’s products are located. Revenue is defined as revenue from external customers. Revenue related to operations in the United States and other geographic areas were:

Geographic revenue data for multi-regional, multi-product transactions reflect internal allocations and are therefore subject to certain assumptions and to the Company’s methodology.

22

One customer, including its subsidiaries, accounted for greater than 10% of the Company's total revenue for the three and six months ended April 30, 2020 and for the three and six months ended April 30, 2019, respectively.

Note 17. Income Taxes

Effective Tax Rate

The Company estimates its annual effective tax rate at the end of each fiscal quarter. The effective tax rate takes into account the Company's 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 presents the provision (benefit) for income taxes and the effective tax rates:

	Three Months Ended   April 30,						Six Months Ended   April 30,
	2020			2019			2020			2019
	(in thousands)
Income before income taxes	$	110,166		$	133,917		$	209,739		$	280,972
Provision (benefit) for income taxes	$	246		$	15,707		$	(4,242	)	$	9,248
Effective tax rate	0.2		%	11.7		%	(2.0		)%	3.3		%

Beginning in the Company's fiscal 2019, the annual statutory federal corporate tax rate is 21%.

The Company’s effective tax rate for the six months ended April 30, 2020 is lower than the statutory federal corporate tax rate of 21.0% primarily due to U.S. federal and California tax research credits, foreign-derived intangible income deduction, excess tax benefits from stock-based compensation, and the realizability of 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.

The Company's effective tax rate decreased in the three months ended April 30, 2020 as compared to the same period in fiscal 2019, primarily due to an increase in excess tax benefits from stock based compensation and inclusion of unrecognized foreign tax benefits for the three months ended April 30, 2019. The Company's effective tax rate decreased in the six months ended April 30, 2020, as compared to the same period in fiscal 2019, primarily due to an increase in excess tax benefits from stock-based compensation and the realization of U.S. foreign tax credits.

The U.S. Treasury Department has issued proposed regulations that could impact the calculation of income taxes. While the Company continues to evaluate the potential impact on its estimated annual tax rate, certain regulations have not been finalized and are subject to change.

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. The Company believes that in the coming 12 months, it is reasonably possible that either certain audits and ongoing tax litigation

23

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 $62 million.

Intra-Entity Transfers of Assets

In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory.” This ASU requires the immediate recognition of current and deferred income tax effects of intra-entity transfers of assets other than inventory. This ASU was adopted on the first day of fiscal 2019. As a result of the adoption, the Company recorded a decrease of approximately $130.5 million in retained earnings as of the beginning of the period of adoption, with a corresponding decrease in prepaid taxes related to the unamortized tax expense attributed to intra-entity transfers of assets other than inventory previously deferred. The Company will recognize the income tax consequences of new intra-entity transfers of assets other than inventory in the consolidated statements of operations in the period when the transaction takes place.

Non-U.S. Examinations

Hungarian Tax Authority

In July 2017, the Hungarian Tax Authority (the HTA) issued a final assessment against the Company’s Hungarian subsidiary (Synopsys Hungary) for fiscal years 2011 through 2013. The HTA has applied withholding taxes on certain payments made to affiliates, resulting in an aggregate tax assessment of approximately $25.0 million and interest and penalties of $11.0 million (at current exchange rates). On August 2, 2017, Synopsys Hungary filed a claim contesting the final assessment with the Hungarian Administrative Court (the Court). In the first quarter of fiscal 2018, Synopsys Hungary paid the assessments, penalties and interest as required by law and recorded these amounts as prepaid taxes on its balance sheet, while continuing its challenge to the assessment through the Court. On April 30, 2019, the Court ruled against Synopsys Hungary. The Court's opinion was received on May 16, 2019 and Synopsys Hungary filed an appeal with the Hungarian Supreme Court on July 5, 2019. In the second quarter of 2019, as a result of the Court's decision, the Company recorded a tax expense due to an unrecognized tax benefit of $17.4 million, which is net of estimated U.S. foreign tax credits for the tax assessments. A Hungarian Supreme Court hearing date set for April 16, 2020 was postponed due to the COVID-19 pandemic. As of April 30, 2020, Synopsys Hungary has requested but not yet received a new hearing date, which would be granted at the discretion of the Hungarian Supreme Court.

In the second quarter of fiscal 2020, the Company reached a final settlement with the HTA for fiscal years 2014 through 2018 and recognized a net $6.9 million in previously unrecognized tax benefits.

National Taxation Bureau of Taipei

In the first quarter of fiscal 2019, the Company reached final settlement with the National Taxation Bureau of Taipei for fiscal year 2017 and recognized $5.5 million in previously unrecognized tax benefits.

The Company is also under examination by the tax authorities in certain other jurisdictions. No material assessments have been proposed in these examinations.

Note 18. Contingencies

Legal Proceedings

The Company is subject to routine legal proceedings, as well as demands, claims and threatened litigation that arise in the normal course of its business. The ultimate outcome of any litigation is often uncertain and unfavorable outcomes could have a negative impact on the Company’s results of operations and financial condition. The Company regularly 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 is estimable, the Company accrues 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.

The Company has determined that, except as set forth below, no disclosure of estimated loss is required for a claim against the Company 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 the Company’s Annual Report on Form 10-K for the fiscal year ended October 31, 2019 (the Annual Report). See Note 7. Commitments and Contingencies of the Annual Report for further information.

Tax Matters

The Company undergoes 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 is 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, the Company would accrue a liability for the estimated expense.

In addition to the foregoing, the Company is, from time to time, party to various other claims and legal proceedings in the ordinary course of its business, including with tax and other governmental authorities. See Note 17. Income Taxes for a description of certain of these other matters.

Note 19. Effect of New Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13) and subsequently issued amendments to the initial guidance: ASU 2018-19, ASU 2019-04 and ASU 2019-05 (collectively, Topic 326). Topic 326 requires measurement and recognition of expected credit losses for financial assets held. Topic 326 is effective for fiscal 2021, and earlier adoption is permitted beginning in the first quarter of fiscal 2020. The adoption of Topic 326 will not have material impact to the Company's consolidated financial statements.

Overview

Business Summary

Synopsys, Inc. provides products and services used across the entire silicon to software spectrum, from engineers creating advanced semiconductors to software developers seeking to ensure the security and quality of their code. We are a global leader in supplying the electronic design automation (EDA) software that engineers use to design and test integrated circuits (ICs), also known as chips. We also offer semiconductor intellectual property (IP) products, which are pre-designed circuits that engineers use as components of larger chip designs rather than designing those circuits themselves. We provide software and hardware used to validate the electronic systems that incorporate chips and the software that runs on them. To complement these offerings, we provide technical services and support to help our customers develop advanced chips and electronic systems. These products and services are part of our Semiconductor & System Design segment.

We are also a leading provider of software tools and services that improve the security and quality of software code in a wide variety of industries, including electronics, financial services, media, automotive, medicine, energy and industrials. These tools and services are part of our Software Integrity segment.

Our EDA and IP customers are generally semiconductor and electronics systems companies. Our solutions help these companies overcome the challenges of developing increasingly advanced electronics products while also helping them reduce their design and manufacturing costs. While our products are an important part of our customers’ development process, our sales could be affected based on their research and development budgets, and our customers' spending decisions may be affected by their business outlook and willingness to invest in new and increasingly complex chip designs.

Our Software Integrity business delivers products and services that enable software developers to test their code - while it is being written - for known security vulnerabilities and quality defects, as well as testing for open source

26

security vulnerabilities and license compliance. Our Software Integrity customers are software developers across many industries, including, but also well beyond, the semiconductor and systems industries. Our Software Integrity products and services form a platform that helps our customers build security into the software development lifecycle and across the entire cyber supply chain.

We have consistently grown our revenue since 2005, despite periods of global economic uncertainty. We achieved these results because of our solid execution, leading technologies and strong customer relationships, and because we recognize our revenue for the software licenses over the arrangement period, which typically approximates three years. See Note 2 of Notes to Unaudited Condensed Consolidated Financial Statements for discussion on our revenue recognition policy. Time-based revenue consists of time-based products, maintenance and service revenue. The revenue we recognize in a particular period generally results from selling efforts in prior periods rather than the current period. As a result, decreases as well as increases in customer spending do not immediately affect our revenues in a significant way.

Our growth strategy is based on building on our leadership in our EDA products, expanding and proliferating our IP offerings, and driving growth in the software security and quality market. As we continue to expand our product portfolio and our total addressable market, for instance in the software security and quality space, we expect to experience increased variability in our total revenue. In addition, due to our adoption of ASC 606 in the beginning of fiscal 2019, the way in which we are required to account for certain types of arrangements has increased the variability in our total revenue from period to period. Nevertheless, the accounting impact has not affected our cash generated from our business. Based on our leading technologies, customer relationships, business model, diligent expense management, and acquisition strategy, we believe that we will continue to execute our strategies successfully.

COVID-19 Pandemic

Although the COVID-19 pandemic has caused minor disruptions to our business operations, it has had a limited impact on our operating results thus far. Given the unpredictable nature of the COVID-19 pandemic's impact on the global economy, historical results may not be an indication of future performance.

The extent to which the COVID-19 pandemic impacts our business operations in future periods will depend on multiple uncertain factors, including the duration and scope of the pandemic, its overall negative impact on the global economy generally and the semiconductor and electronics industries specifically, and continued responses by governments and businesses to COVID-19. We have not identified trends that we expect will materially impact our future operating results at this time. As we recognize our revenue for software licenses over the arrangement period, any potential impact related to COVID-19 may be delayed. We have not observed any changes in the design activity of customers, but we have experienced a slowdown in customer commitments in our Software Integrity segment. We have also experienced minor disruptions in our hardware supply chain, which we have been able to address with minimal impact to our business operations to date.

We will continue to consider the potential impact of the COVID-19 pandemic on our business operations. Although no material impairment or other effects have been identified to date related to the COVID-19 pandemic, there is substantial uncertainty in the nature and degree of its continued effects over time. That uncertainty affects management’s accounting estimates and assumptions, which could result in greater variability in a variety of areas that depend on these estimates and assumptions as additional events and information become known.

See Part II, Item 1A, Risk Factors for further discussion of the possible impact of the COVID-19 pandemic on our business, operations and financial condition.

Business Segments

The CODMs regularly review disaggregated information for the following two reportable segments: (1) Semiconductor & System Design, which includes EDA tools, IP products, system integration solutions and other associated revenue categories, and (2) Software Integrity, which includes a comprehensive solution for building integrity—security, quality and compliance testing—into our customers’ software development lifecycle and supply chain.

Semiconductor & System Design. This segment includes our advanced silicon design, verification products and services, and semiconductor IP portfolio, which encompasses products and services that serve companies primarily in the semiconductor and electronics industries. EDA includes digital, custom and Field Programmable Gate Array (FPGA) IC design software, verification products, and manufacturing software products. Designers use these

27

products to automate the highly complex IC design process and to reduce defects that could lead to expensive design or manufacturing re-spins or suboptimal end products. For IP, we are a leading provider of high-quality, silicon-proven IP solutions for system-on-chips (SoCs). This includes IP that has been optimized to address specific application requirements for the mobile, automotive, digital home, internet of things, and cloud computing markets, enabling designers to quickly develop SoCs in these areas.

Software Integrity. This segment includes a broad portfolio of products and services such as leading quality testing technologies, automated analysis, and consulting experts. Beginning in fiscal 2019, we launched the Polaris Software Integrity Platform™, an integrated cloud-based solution that unites key elements to provide an even more valuable way for developers to better develop personalized approaches for open source license compliance and detect and remediate known security vulnerabilities and quality defects early in the development process, thereby minimizing risk and maximizing productivity.

Fiscal Year End

Our fiscal year 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 2020 and 2019 are 52-week years ending on October 31, 2020 and November 2, 2019, respectively.

Our results of operations for the three and six months of fiscal 2020 and 2019 ended on May 2, 2020 and May 4, 2019, respectively. For presentation purposes, this Form 10-Q refers to the closest calendar month end.

Financial Performance Summary

In the second quarter of fiscal 2020 compared to the same period of fiscal 2019, our financial performance reflects the following:

• Revenues were $861.3 million, an increase of $25.1 million, primarily due to our continued organic growth.

• Total cost of revenue and operating expenses were $735.5 million, an increase of $14.7 million, primarily due to increases in employee-related costs of $33.0 million resulting from increases in organic growth and acquisitions, and restructuring costs of $15.3 million, partially offset by lower deferred compensation expenses of $34.8 million.

• Operating income was $125.9 million, an increase of $10.4 million or 9%.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial results under Results of Operations below are based on our unaudited condensed consolidated financial statements, which we have prepared in accordance with U.S. GAAP. In preparing these financial statements, we make assumptions, judgments and estimates that can affect the reported amounts of assets, liabilities, revenues and expenses, and net income. On an ongoing basis, we evaluate our estimates based on historical experience and various other assumptions we believe are reasonable under the circumstances. Our actual results may differ from these estimates. See Note 2 of Notes to Unaudited Condensed Consolidated Financial Statements for further information on our significant accounting policies.

The accounting policies that most frequently require us to make assumptions, judgments and estimates, and therefore are critical to understanding our results of operations, are:

• Revenue recognition;

• Valuation of business combinations; and

• Income taxes.

See Critical Accounting Policies and Estimates in our Annual Report on Form 10-K for the year ended October 31, 2019 for further information.

Results of Operations

Revenue

Our revenues are generated from two business segments: the Semiconductor & System Design segment and the Software Integrity segment. See Note 15 of Notes to Unaudited Condensed Consolidated Financial Statements for additional information about our reportable segments and revenue by geographic regions.

Further disaggregation of the revenues into various products and services within these two segments is summarized as follows:

Semiconductor & System Design Segment

This segment is comprised of the following:

• EDA software includes digital, custom and Field Programmable Gate Array (FPGA) IC design software, verification products and obligations to provide unspecified updates and support services. EDA products and services are typically sold through TSL arrangements that grant customers the right to access and use all of the licensed products at the outset of an arrangement and software updates are generally made available throughout the entire term of the arrangement, which is typically three years. Under ASC 606, we have concluded that the software licenses in TSL contracts are not distinct from the obligation to provide unspecified software updates to the licensed software throughout the license term, because the multiple software licenses represent inputs to a single, combined offering, and timely, relevant software updates are integral to maintaining the utility of the software licenses. We recognize revenue for the combined performance obligation under TSL contracts ratably over the term of the license.

• IP & System Integration includes our DesignWare® IP portfolio and system-level products and services. Under ASC 606, these arrangements generally have two performance obligations which consist of transferring of the licensed IP and providing related support, which includes rights to technical support and software updates that are provided over the support term and are transferred to the customer over a time. Revenue allocated to the IP licenses is recognized at a point in time upon the later of the delivery date or the beginning of the license period, and revenue allocated to support is recognized over the support term. Royalties are recognized as revenue in the quarter in which the applicable customer sells its products that incorporate our IP. Payments for IP contracts are generally received upon delivery of the IP. Revenue related to the customization of certain IP is recognized as “Professional Services.”

• In the case of arrangements involving the sale of Hardware products, we generally have two performance obligations. 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 the 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 portion of 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. We have 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 portion of the transaction price allocated to the maintenance obligation is recognized as revenue ratably over the maintenance term.

• Revenue from Professional Service contracts is recognized over time, generally using costs incurred or hours expended to measure progress. We have a history of reasonably 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.

Software Integrity Segment

• We sell Software Integrity products in arrangements that provide customers the right to software licenses, maintenance updates and technical support. Over the term of these arrangements, the customer expects us to provide integral maintenance updates to the software licenses, which help

29

customers protect their own software from new critical quality defects and potential security vulnerabilities. The licenses and maintenance updates serve together to fulfill our commitment to the customer as both work together to provide the functionality to the customer and represent a combined performance obligation. We will recognize revenue for the combined performance obligation over the term of the arrangement.

Most of our customer arrangements are complex, involving hundreds of products and various license rights, and our customers bargain with us over many aspects of these arrangements. For example, they often demand a broader portfolio of solutions, support and services and seek more favorable terms such as expanded license usage, future purchase rights and other unique rights at an overall lower total cost. No single factor typically drives our customers’ buying decisions, and we compete on all fronts to serve customers in highly competitive markets. Customers generally negotiate the total value of the arrangement rather than just unit pricing or volumes.

Total Revenue

Total	$	1,695.7	$	1,656.6	$	39.1	2	%

The overall growth of our business has been the primary driver of the increase in our revenue. Our revenues are subject to fluctuations, primarily due to customer requirements including the timing and value of contract renewals. For example, we experience fluctuations in our revenue due to factors such as the timing of IP product sales, consulting projects, FSA drawdowns, royalties, and hardware sales. As revenue from IP products sales and hardware sales are recognized upfront, customer demand and timing requirements for such IP products and hardware have resulted in increased variability of our total revenue.

The increase in total revenue for the three months ended April 30, 2020 compared to the same period in fiscal 2019 was primarily attributable to the continued organic growth of the business in time-based and upfront license products, and to a lesser extent, higher maintenance and service revenue. The increase was partially offset by a decrease in the sale of hardware products driven by timing of customer requirements.

The increase in total revenue for the six months ended April 30, 2020 compared to the same period in fiscal 2019 was primarily attributable to the continued organic growth of the business in time-based and upfront license products. The increase was partially offset by a decrease in the sale of hardware products, and maintenance and service revenue due to a decrease in the volume of arrangements that include maintenance.

See Note 15 of Notes to Unaudited Condensed Consolidated Financial Statements for a discussion of revenue by geographic areas.

Six months ended	$	1,146.5		$	1,112.0		$	34.5	3	%
Percentage of total revenue	68		%	67		%

The increase in time-based products for the three and six months ended April 30, 2020 compared to the same periods in fiscal 2019 was primarily attributable to an increase in TSL license revenue from arrangements booked in prior periods.

Upfront Products Revenue

	April 30,
	2020			2019			$ Change			% Change
	(dollars in millions)
Three months ended	$	129.8		$	143.4		$	(13.6	)	(9	)%
Percentage of total revenue	15		%	17		%
Six months ended	$	280.5		$	273.9		$	6.6		2	%
Percentage of total revenue	16		%	17		%

Changes in upfront products revenue are generally attributable to normal fluctuations in the extent and timing of customer requirements, which can drive the amount of upfront orders and revenue in any particular period.

The decrease in upfront products revenue for the three months ended April 30, 2020 compared to the same period in fiscal 2019 was primarily due to a decrease in the sale of hardware products driven by timing of customer requirements. The decrease was partially offset by an increase in the sale of IP products driven by higher demand from customers and to a lesser extent contributions from acquisitions.

The increase in upfront products revenue for the six months ended April 30, 2020 compared to the same period in fiscal 2019 was primarily due to an increase in the sale of IP products driven by higher demand from customers and contributions from acquisitions. The increase was partially offset by a decrease in the sale of hardware products driven by timing of customer requirements.

Upfront products revenue as a percentage of total revenue will likely fluctuate based on the timing of IP products and hardware sales. Such fluctuations will continue to be impacted by the timing of shipments or FSA drawdowns due to customer requirements.

Maintenance and Service Revenue

	April 30,
	2020			2019			$ Change			% Change
	(dollars in millions)
Three months ended
Maintenance revenue	$	44.9		$	39.4		$	5.5		14	%
Professional services and other revenue	96.6			95.1			1.5			2	%

Total maintenance and service revenue	$	268.7		$	270.7		$	(2.0	)	(1	)%
Percentage of total revenue	16		%	16		%

The increase and decrease, respectively, in maintenance revenue for the three and six months ended April 30, 2020 compared to the same periods in fiscal 2019 were primarily due to changes in the volume of arrangements that include maintenance.

The increase in professional services and other revenue for the three and six months ended April 30, 2020 compared to the same periods in fiscal 2019 was primarily due to the timing of IP consulting projects.

Cost of Revenue

	April 30,
	2020			2019			$ Change			% Change
	(dollars in millions)
Three months ended
Cost of products revenue	$	108.2		$	116.0		$	(7.8	)	(7	)%
Cost of maintenance and service revenue	62.2			59.8			2.4			4	%
Amortization of intangible assets	13.8			14.9			(1.1		)	(7	)%
Total	$	184.3		$	190.7		$	(6.4	)	(3	)%
Percentage of total revenue	21		%	23		%
Six months ended
Cost of products revenue	$	226.0		$	232.6		$	(6.6	)	(3	)%
Cost of maintenance and service revenue	124.1			118.6			5.5			5	%
Amortization of intangible assets	27.0			32.3			(5.3		)	(16	)%
Total	$	377.1		$	383.6		$	(6.5	)	(2	)%
Percentage of total revenue	22		%	23		%

We divide cost of revenue into three categories: cost of products revenue, cost of maintenance and service revenue, and amortization of intangible assets. We segregate expenses directly associated with consulting and training services from cost of products revenue associated with internal functions providing license delivery and post-customer contract support services. We then allocate these group costs between cost of products revenue and cost of maintenance and service revenue based on products and maintenance and service revenue reported.

Cost of products revenue. Cost of products revenue includes costs related to products sold and software licensed, allocated operating costs related to product support and distribution costs, royalties paid to third-party vendors, and the amortization of capitalized research and development costs associated with software products that had reached technological feasibility.

Cost of maintenance and service revenue. Cost of maintenance and service revenue includes operating costs related to maintaining the infrastructure necessary to operate our services and costs to deliver our consulting services, such as hotline and on-site support, production services and documentation of maintenance updates. We

32

expect our cost of maintenance and service revenue to increase in future periods because of recent acquisitions, but we do not expect the impact to be material to our total cost of revenue.

Amortization of intangible assets. Amortization of intangible assets, which is recorded to cost of revenue and operating expenses, includes the amortization of core/developed technology, trademarks, trade names, customer relationships, covenants not to compete related to acquisitions and certain contract rights related to acquisitions.

The decrease in cost of revenue for the three months ended April 30, 2020 compared to the same period in fiscal 2019 was primarily due to a decrease of $7.5 million in hardware costs and lower deferred compensation expenses of $3.7 million, partially offset by an increase of $3.0 million in personnel-related expenses as a result of headcount increase from organic hiring and acquisitions.

The decrease in cost of revenue for the six months ended April 30, 2020 compared to the same period in fiscal 2019 was primarily due to a decrease of $15.0 million in hardware costs and lower deferred compensation expenses of $2.8 million, partially offset by increases of $8.6 million in personnel-related costs as a result of headcount increases from organic hiring and acquisitions, $3.1 million in depreciation and maintenance expenses, $2.4 million in facility expenses, and $2.0 million in consulting costs primarily related to servicing IP consulting arrangements.

Changes in other cost of revenue categories for the above-mentioned periods were not individually material.

Six months ended	$	299.1		$	314.6		$	(15.5	)	(5	)%
Percentage of total revenue	18		%	19		%

The decrease in sales and marketing expenses for the three months ended April 30, 2020 compared to the same period in fiscal 2019 was primarily due to lower deferred compensation expenses of $6.8 million and a decrease of $5.8 million in travel and marketing communication expenses as a result of travel restrictions related to COVID-19, partially offset by an increase in personnel-related costs of $1.1 million.

33

The decrease in sales and marketing expenses for the six months ended April 30, 2020 compared to the same period in fiscal 2019 was primarily due to decreases of $7.7 million in travel and marketing communication expenses as a result of travel restrictions related to COVID-19, $2.8 million in personnel-related costs and lower deferred compensation expenses of $5.2 million.

Changes in other sales and marketing expense categories for the above-mentioned periods were not individually material.

Percentage of total revenue	8		%	6		%

The increase in general and administrative expenses for the three months ended April 30, 2020 compared to the same period in fiscal 2019 was primarily due to increases of $3.6 million in personnel-related costs and $1.6 million in professional service costs primarily due to additional legal services related to various projects, partially offset by lower deferred compensation expenses of $3.9 million.

The increase in general and administrative expenses for the six months ended April 30, 2020 compared to the same period in fiscal 2019 was primarily due to a legal settlement of $18.3 million in our favor in the first quarter of fiscal 2019 and increases of $8.0 million in personnel-related expenses and $5.6 million in depreciation and maintenance expenses, partially offset by lower deferred compensation expenses of $2.9 million.

Changes in other general and administrative expense categories for the above-mentioned periods were not individually material.

Amortization of Intangible Assets

Amortization of intangible assets includes the amortization of contract rights and the amortization of core/developed technology, trademarks, trade names, customer relationships, and in-process research and development related to acquisitions completed in prior years. Amortization expense is included in the unaudited condensed consolidated statements of operations as follows:

The decrease in amortization of intangible assets for the three and six months ended April 30, 2020 compared to the same periods in fiscal 2019 was primarily due to intangible assets that were fully amortized, partially offset by additions of acquired intangible assets.

Restructuring Charges

In the second quarter of fiscal 2019, our management approved, committed and initiated a restructuring plan (the Plan) as part of a business reorganization. Total charges under the Plan was $86.0 million and consisted primarily of severance, termination, and retirement benefits under the 2019 Voluntary Retirement Program (VRP).

During the three and six months ended April 30, 2020, we incurred restructuring charges of approximately $29.7 million and $38.4 million, respectively, for involuntary employee termination actions and the VRP related to the 2019 restructuring plan. As of April 30, 2020, $30.3 million remained outstanding.

During the three and six months ended April 30, 2019, we incurred restructuring charges of approximately $14.7 million as part of a business realignment under both the 2019 VRP and the 2018 restructuring plan.

The net decrease in other income (expense) for the three and six months ended April 30, 2020 as compared to the same periods in fiscal 2019 was primarily due to a loss in the market value of our executive deferred compensation plan assets compared to a gain in the corresponding periods.

Segment Operating Results

We do not allocate certain operating expenses managed at a consolidated level to our reportable segments. These unallocated expenses consist primarily of stock-based compensation expense, amortization of intangible assets, restructuring, litigation and acquisition-related costs. See Note 15 of Notes to Unaudited Condensed Consolidated Financial Statements for more information.

The increase in adjusted operating income for the three and six months ended April 30, 2020 compared to the same periods in fiscal 2019 was primarily due to an increase in revenue from arrangements booked in prior periods.

Income Taxes

Our effective tax rate decreased in the three months ended April 30, 2020 as compared to the same period in fiscal 2019, primarily due to an increase in excess tax benefits from stock-based compensation and inclusion of unrecognized foreign tax benefits for the three months ended April 30, 2019. Our effective tax rate decreased in the six months ended April 30, 2020, as compared to the same period in fiscal 2019, primarily due to an increase in excess tax benefits from stock-based compensation and the realization of U.S. foreign tax credits.

See Note 17 of Notes to Unaudited Condensed Consolidated Financial Statements for further discussion of the provision for income taxes and impacts related to the Tax Act.

Liquidity and Capital Resources

Our sources of cash and cash equivalents are funds generated from our business operations and funds that may be drawn down under our revolving credit and term loan facilities.

We have considered the potential impact of the COVID-19 pandemic on our liquidity and capital resources. Although we have not observed any material effects on our liquidity, collections from customers or other working capital requirements due to the COVID-19 pandemic to date, there is substantial uncertainty that could result in greater variability as additional events and information become known. We believe that our existing balances of cash and cash equivalents will be sufficient to satisfy our working capital needs, capital asset purchases, share repurchases, acquisitions, debt repayments and other liquidity requirements associated with our existing operations. We are continuously evaluating the COVID-19 pandemic’s effects and taking steps to mitigate known risks, including potential constraints on our liquidity and capital resources as a result of customers’ reduced

36

expenditures or disruptions to our supply chain. In light of that ongoing assessment, we may choose to temporarily defer certain expenditures due to the effects of the COVID-19 pandemic.

As of April 30, 2020, we held an aggregate of $313.1 million in cash and cash equivalents in the United States and an aggregate of $543.3 million in our foreign subsidiaries. As a result of the Tax Act, if we decide to repatriate the undistributed earnings of our foreign subsidiaries for use in the U.S. in the future, the earnings made after December 31, 2017 would not be subject to further U.S. federal tax. In addition, we have provided foreign deferred taxes on our undistributed earnings, which is sufficient to address the incremental tax that would be due on future foreign earnings.

The following sections discuss changes in our unaudited condensed consolidated balance sheets and statements of cash flows, and other commitments of our liquidity and capital resources during the six months ended April 30, 2020.

Cash and Cash Equivalents

	April 30, 2020		October 31, 2019		$ Change		% Change
	(dollars in millions)
Cash and cash equivalents	$	856.4	$	728.6	$	127.8	18	%

Cash and cash equivalents increased primarily due to cash from our operations and net proceeds from our credit facilities. The increase in cash and cash equivalents was partially offset by stock repurchases, repayment of debt, cash used for acquisitions, and purchases of property and equipment.

Cash Flows

	Six Months Ended   April 30,
	2020			2019			$ Change
	(dollars in millions)
Cash provided by operating activities	$	389.7		$	208.8		$	180.9
Cash used in investing activities	(236.7		)	(66.3		)	(170.4		)
Cash used in financing activities	(20.7		)	(237.6		)	216.9

Cash Provided by Operating Activities

We expect cash from our operating activities to fluctuate as a result of a number of factors, including the timing of our billings and collections, our operating results, and the timing and amount of tax and other liability payments. Cash provided by our operations is dependent primarily upon the payment terms of our license agreements. We generally receive cash from upfront arrangements much sooner than from time-based products revenue, in which the license fee is typically paid either quarterly or annually over the term of the license.

Cash provided by operating activities for the six months ended April 30, 2020 was higher compared to the same period in fiscal 2019, primarily attributable to higher deferred revenue due to timing of contracts and invoicing and lower disbursements in operations, including vendors and tax payments.

Cash Used in Investing Activities

Cash used in investing activities for the six months ended April 30, 2020 was higher compared to the same period in fiscal 2019, primarily due to higher cash paid for acquisitions of $151.2 million.    

Cash Used in Financing Activities

Cash used in financing activities for the six months ended April 30, 2020 was lower compared to the same period in fiscal 2019, primarily due to lower debt repayments of $188.1 million and higher proceeds of $87.7 million from credit facilities drawdowns, partially offset by higher stock repurchase activities of $70.8 million.

37

Accounts Receivable, net

	April 30, 2020		October 31, 2019		$ Change		% Change
	(dollars in millions)
Accounts Receivable, net	$	634.8	$	553.9	$	80.9	15	%

Changes in our accounts receivable balance are primarily driven by the timing of customer billing and collection activities.

Working Capital

Working capital is comprised of current assets less current liabilities, as shown on our unaudited condensed consolidated balance sheets:

	April 30, 2020			October 31, 2019			$ Change			% Change
	(dollars in millions)
Current assets	$	1,960.8		$	1,738.9		$	221.9		13	%
Current liabilities	2,054.2			1,752.5			301.7			17	%
Working capital (deficit)	$	(93.4	)	$	(13.6	)	$	(79.8	)	587	%

Increases in our working capital deficit were primarily due to an increase in deferred revenue of $184.0 million, an increase in short-term debt of $103.8 million, an increase in current operating lease liabilities of $72.5 million, partially offset by an increase in cash and cash equivalents of $127.8 million, an increase in accounts receivable of $80.9 million and a decrease in accounts payable and accrued liabilities of $59.4 million. We did not see an impact on our working capital deficit during this period from the COVID-19 pandemic.

Other Commitments — Credit and Term Loan Facilities

On November 28, 2016, we entered into an amended and restated credit agreement with several lenders (the Credit Agreement) providing for (i) a $650.0 million senior unsecured revolving credit facility (the Revolver) and (ii) a $150.0 million senior unsecured term loan facility (the Term Loan). The Credit Agreement amended and restated our previous credit agreement dated May 19, 2015, in order to increase the size of the revolving credit facility from $500.0 million to $650.0 million, provide a new $150.0 million senior unsecured term loan facility, and extend the termination date of the revolving credit facility from May 19, 2020 to November 28, 2021. Subject to obtaining additional commitments from lenders, the principal amount of the loans provided under the Credit Agreement may be increased by us by up to an additional $150.0 million. The Credit Agreement contains financial covenants requiring us to operate within a maximum leverage ratio and maintain a minimum interest coverage ratio, as well as other non-financial covenants. As of April 30, 2020, we were in compliance with all financial covenants.

As of April 30, 2020, we had $111.4 million outstanding balance, net of debt issuance costs, under the Term Loan, of which $90.0 million was classified as long-term liabilities. Outstanding principal payments under the Term Loan are due as follows:

Fiscal year	(in thousands)
Remainder of fiscal 2020	$	9,376
2021	27,187
2022	75,000
Total	$	111,563

In July 2018, we entered into a 220.0 million RMB (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 Chinese Central Bank rate plus 10% of such rate. As of April 30, 2020, we had $24.4 million outstanding under the agreement.

As of October 31, 2019, we had $119.8 million outstanding balance, net of debt issuance costs, under the Term Loan, of which $102.2 million was classified as long-term liabilities. There was no outstanding balance under the Revolver as of October 31, 2019.

38

There was $100.0 million outstanding balance under the Revolver as of April 30, 2020. We expect our borrowings 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, 2020, borrowings under the Term Loan bore interest at LIBOR +1.125% and the applicable interest rate for the Revolver was 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.

Other

As of April 30, 2020, our cash equivalents consisted of taxable money market mutual funds. We follow an established investment policy and set of guidelines to monitor, manage and limit our exposure to interest rate and credit risk.

We proactively manage our cash equivalents balances and closely monitor our capital and stock repurchase expenditures to ensure ample liquidity. Additionally, we believe the overall credit quality of our portfolio is strong, with our global excess cash, and our cash equivalents, invested in banks and securities with a weighted-average credit rating exceeding AA. The majority of our investments are classified as Level 1 or Level 2 investments, as measured under fair value guidance. See Notes 6 and 7 of Notes to Unaudited Condensed Consolidated Financial Statements.

We believe that our current cash and cash equivalents, cash generated from operations, and available credit under our Revolver will satisfy our routine business requirements for at least the next 12 months and the foreseeable future.

Contractual Obligations

Contractual obligations as of April 30, 2020 are as follows:

	Total		Remainder of Fiscal 2020		Fiscal 2021/ Fiscal 2022		Fiscal 2023/ Fiscal 2024		Thereafter		Other
	(in thousands)
Operating leases	$	603,017	$	43,314	$	155,359	$	109,844	$	294,500	$	—
Purchase obligations(1)	365,500		186,721		169,234		9,545		—		—
Other obligations(2)	237,226		134,176		103,050		—		—		—
Long-term accrued income taxes(3)	24,589		—		—		—		24,589		—
Total	$	1,230,332	$	364,211	$	427,643	$	119,389	$	319,089	$	—

⁽¹⁾  Purchase obligations represent an estimate of all open purchase orders and contractual obligations in the ordinary course of business for which we have not received the goods or services as of April 30, 2020. Although open purchase orders are considered enforceable and legally binding, the terms generally allow us the option to cancel, reschedule, and adjust our requirements based on our business needs prior to the delivery of goods or performance of services.

⁽²⁾  These other obligations include our Term Loan, Revolver, credit facilities, and associated fees.

⁽³⁾  Long-term accrued income taxes represent uncertain tax benefits as of April 30, 2020. Currently, a reasonably reliable estimate of timing of payments related to uncertain tax benefits in individual years beyond fiscal 2020 cannot be made due to uncertainties in timing of the commencement and settlement of potential tax audits.

The expected timing of payments of the obligations discussed above is estimated based on current information. Timing of payment and actual amounts paid may be different depending on the time of receipt of goods or services or changes to agreed-upon amounts for some obligations.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

See Other Commitments — Credit and Term Loan Facilities, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations, regarding borrowings under our senior unsecured revolving credit facility.

As of April 30, 2020, our exposure to market risk has not changed materially since October 31, 2019. For more information on financial market risks related to changes in interest rates, reference is made to Item 7A. Quantitative and Qualitative Disclosures about Market Risk contained in Part II of our Annual Report on Form 10-K for the fiscal year ended October 31, 2019, filed with the SEC on December 20, 2019.

40

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures. As of April 30, 2020, Synopsys carried out an evaluation under the supervision and with the participation of Synopsys’ management, including the Co-Chief Executive Officers and Chief Financial Officer, of the effectiveness of the design and operation of Synopsys’ disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). There are inherent limitations to the effectiveness of any system of disclosure controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable, not absolute, assurance of achieving their control objectives. Our Co-Chief Executive Officers and Chief Financial Officer have concluded that, as of April 30, 2020, Synopsys’ disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports Synopsys files and submits under the Exchange Act is recorded, processed, summarized and reported as and when required, and that such information is accumulated and communicated to Synopsys’ management, including the Co-Chief Executive Officers and Chief Financial Officer, to allow timely decisions regarding its required disclosure.

(b) Changes in Internal Control over Financial Reporting. There were no additional changes in Synopsys’ internal control over financial reporting during the fiscal quarter ended April 30, 2020 that have materially affected, or are reasonably likely to materially affect, Synopsys’ internal control over financial reporting.

41

PART II. OTHER INFORMATION

Item 1. 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. Regardless of outcome, litigation can have an adverse impact on Synopsys because of the defense costs, diversion of management resources and other factors.

We regularly review the status of each significant matter and assess its 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.

In July 2017, the Hungarian Tax Authority (HTA) issued a final assessment against our Hungarian subsidiary (Synopsys Hungary) for fiscal years 2011 through 2013. The HTA has disallowed Synopsys Hungary's tax positions taken during these years regarding the timing of the deduction of research expenses and applied withholding taxes on certain payments made to affiliates, resulting in an aggregate tax assessment of approximately $44.5 million and interest and penalties of $18.0 million. On August 2, 2017, Synopsys Hungary filed a claim contesting the final assessment with the Hungarian Administrative Court (the Court). On November 16, 2017, Synopsys Hungary paid the assessment as required by law, while continuing its challenge to the assessment in court. Hearings were held in February and July 2018, February 26, 2019 and April 30, 2019. On December 10, 2018, Synopsys Hungary withdrew its claim contesting the final assessment with regard to the timing of the deduction of research expenses, resulting in a remaining disputed tax assessment of approximately $25.0 million and interest and penalties of $11.0 million. On April 30, 2019, the Court ruled against Synopsys Hungary. The Court's opinion was received on May 16, 2019. Synopsys Hungary filed an appeal with the Hungarian Supreme Court on July 5, 2019. In the second quarter of 2019, as a result of the Court's decision, we recorded a tax expense due to an unrecognized tax benefit of $17.4 million, which is net of estimated U.S. foreign tax credits for the tax assessments. A Hungarian Supreme Court hearing date set for April 16, 2020 was postponed due to the COVID-19 pandemic. As of April 30, 2020, we have requested but not yet received a new hearing date, which would be granted at the discretion of the Hungarian Supreme Court.

Item 1A. Risk Factors

A description of the risk factors associated with our business is set forth below. Investors should carefully consider these risks and uncertainties before investing in our common stock.

The COVID-19 pandemic could have a material adverse effect on our business, operations and financial condition.

The COVID-19 pandemic has caused minor disruptions to our business operations to date and could have a material adverse effect on our business, operations and financial condition in the future. For example, we have experienced limited hardware supply chain and logistical challenges as well as a slowdown in customer commitments in our Software Integrity segment. In response to the COVID-19 novel coronavirus pandemic, governments and businesses have taken unprecedented actions to contain the virus, including social distancing, travel restrictions, shelter-in-place orders and restrictions on non-essential businesses. These restrictions have significantly curtailed global economic activity and have caused substantial volatility and disruption in global financial markets. We have transitioned most of our employees in affected regions to work remotely in order to comply with applicable restrictions, and have implemented travel restrictions and other changes to our business operations. It is unclear when a return to our offices in affected regions will be permitted, or what limitations will be in place once our employees return to our offices. We have modified, and may further modify, our business practices in response to the risks and negative impacts caused by the COVID-19 pandemic, but we cannot be certain that these measures will be successful.

The extent to which the COVID-19 pandemic impacts our business operations in future periods will depend on multiple uncertain factors, including the duration and scope of the pandemic, its overall negative impact on the global economy, continued responses by governments and businesses to COVID-19, the ability to secure timely payment from customers, the ability to accurately estimate customer demand, reduced willingness of current and potential customers to purchase our products and services due to their own business and market uncertainties, the ability of our business partners and third-party providers to fulfill their responsibilities and commitments, the ability to secure adequate and timely supply of equipment and materials from suppliers for our hardware products, and the ability to develop and deliver our products. In addition, continued weak economic conditions may result in impairment in value of our tangible and intangible assets. The impact of the COVID-19 pandemic may also have the effect of heightening many of the other risks and uncertainties described in this “Risk Factors” section.

The growth of our business depends primarily on the semiconductor and electronics industries.

The growth of the electronic design automation (EDA) industry as a whole, our Semiconductor & System Design segment product sales, and to some extent our Software Integrity segment product sales, is dependent on the semiconductor and electronics industries. A substantial portion of our business and revenue depends upon the commencement of new design projects by semiconductor manufacturers, systems companies, and their customers. The increasing complexity of designs of systems-on-chips, integrated circuits, electronic systems and customers’ concerns about managing costs have previously led and in the future could lead to a decrease in design starts and design activity in general, with some customers focusing more on one discrete phase of the design process or opting for less advanced, but less risky, manufacturing processes that may not require the most advanced EDA products. Demand for our products and services could decrease and our financial condition and results of operations could be adversely affected if growth in the semiconductor and electronics industries slows or stalls, including due to the impact of the COVID-19 pandemic. Additionally, as the EDA industry has matured, consolidation has resulted in stronger competition from companies better able to compete as sole source vendors. This increased competition may cause our revenue growth rate to decline and exert downward pressure on our operating margins, which may have an adverse effect on our business and financial condition.

Furthermore, the semiconductor and electronics industries have become increasingly complex ecosystems. Many of our customers outsource the manufacture of their semiconductor designs to foundries. Our customers also frequently incorporate third-party IP, whether provided by us or other vendors, into their designs to improve the efficiency of their design process. We work closely with major foundries to ensure that our EDA, IP, and manufacturing solutions are compatible with their manufacturing processes. Similarly, we work closely with other major providers of semiconductor IP, particularly microprocessor IP, to optimize our EDA tools for use with their IP designs and to assure that their IP and our own IP products, which may each provide for the design of separate components on the same chip, work effectively together. If we fail to optimize our EDA and IP solutions for use with major foundries’ manufacturing processes or major IP providers’ products, or if our access to such foundry

43

processes or third-party IP products is hampered, then our solutions may become less desirable to our customers, resulting in an adverse effect on our business and financial condition.

Consolidation among our customers and within the industries in which we operate, as well as our dependence on a relatively small number of large customers, may negatively impact our operating results.

A number of business combinations, including mergers, asset acquisitions and strategic partnerships, among our customers in the semiconductor and electronics industries have occurred over the last several years, and more could occur in the future. Consolidation among our customers could lead to fewer customers or the loss of customers, increased customer bargaining power, or reduced customer spending on software and services. Furthermore, we depend on a relatively small number of large customers, and on such customers continuing to renew licenses and purchase additional products from us, for a large portion of our revenue. Reduced customer spending or the loss of a small number of customers, particularly our large customers, could adversely affect our business and financial condition. In addition, we and our competitors from time to time acquire businesses and technologies to complement and expand our respective product offerings. If any of our competitors consolidate or acquire businesses and technologies which we do not offer, they may be able to offer a larger technology portfolio, additional support and service capability, or lower prices, which could negatively impact our business and operating results.

The global nature of our operations exposes us to increased risks and compliance obligations that may adversely affect our business.

We derive roughly half of our revenue from sales outside the United States, and we expect our orders and revenue to continue to depend on sales to customers outside the U.S. We have also continually expanded our non-U.S. operations. This strategy requires us to recruit and retain qualified technical and managerial employees, manage multiple remote locations performing complex software development projects and ensure intellectual property protection outside of the U.S. Our international operations and sales subject us to a number of increased risks, including:

• Ineffective or weaker legal protection of intellectual property rights;

• Uncertain economic and political conditions in countries where we do business;

• Government trade restrictions, including tariffs, export licenses, or other trade barriers, and changes to existing trade arrangements between various countries;

• Difficulties in adapting to cultural differences in the conduct of business, which may include business practices in which we are prohibited from engaging by the Foreign Corrupt Practices Act or other anti-corruption laws;

• Financial risks such as longer payment cycles and difficulty in collecting accounts receivable;

• Inadequate local infrastructure that could result in business disruptions;

• Additional taxes, interest, and potential penalties, and uncertainty around changes in tax laws of various countries; and

• Other factors beyond our control such as natural disasters, terrorism, civil unrest, war, and infectious diseases and pandemics, including COVID-19.

Furthermore, if any of the foreign economies in which we do business deteriorate or if we fail to effectively manage our global operations, our business and results of operations will be harmed.

There is inherent risk, based on the complex relationships between certain Asian countries and the United States, that political, diplomatic, or military events could result in trade disruptions, including tariffs, trade embargoes, export restrictions and other trade barriers. A significant trade disruption, export restriction, or the establishment or increase of any trade barrier in any area where we do business could reduce customer demand and cause customers to search for substitute products and services, make our products and services more expensive or unavailable for customers, increase the cost of our products and services, have a negative impact on customer confidence and spending, make our products less competitive, or otherwise have a materially adverse impact on our future revenue and profits, our customers' and suppliers’ businesses, and our results of operations.

44

For example, beginning in May 2019, the United States government placed certain entities on the “Entity List,” restricting the sale of U.S. technologies to the named entities. As a result of this government action, we are not able to book new business with these entities, and revenue associated with these entities is put “on hold” until either the contract expires, or the restriction is lifted. In addition, in May 2020, the United States government placed further restrictions on certain entities on the Entity List to prevent them from sharing designs developed using U.S. software or technology with other entities on the Entity List and obtaining semiconductors manufactured with processes that use U.S. software and technology. The impact of this latest restriction on our business is unclear at this time. In response to these actions or similar actions taken by the United States, other countries may adopt tariffs and trade barriers that could limit our ability to offer our products and services. Current and potential customers who are concerned or affected by such tariffs or restrictions may respond by developing their own products or replacing our solutions, which would have an adverse effect on our business. In addition, government or customer efforts, attitudes, laws, or policies regarding technology independence may lead to non-U.S. customers favoring their domestic technology solutions that could compete with or replace our products, which would also have an adverse effect on our business.

In addition to tariffs and other trade barriers, our global operations are subject to numerous U.S. and foreign laws and regulations, including those related to anti-corruption, tax, corporate governance, imports and exports, financial and other disclosures, privacy and labor relations. These laws and regulations are complex and may have differing or conflicting legal standards, making compliance difficult and costly. In addition, there is uncertainty regarding how proposed, contemplated or future changes to these complex laws and regulations could affect our business. We may incur substantial expense in complying with the new obligations to be imposed by these laws and regulations, and we may be required to make significant changes in our business operations, all of which may adversely affect our revenues and our business overall. If we violate these laws and regulations, we could be subject to fines, penalties or criminal sanctions, and may be prohibited from conducting business in one or more countries. Although we have implemented policies and procedures to help ensure compliance with these laws and regulations, there can be no assurance that our employees, contractors, agents or partners will not violate such laws and regulations. Any violation individually or in the aggregate could have a material adverse effect on our operations and financial condition.

Our financial results are also affected by fluctuations in foreign currency exchange rates. A weakening U.S. dollar relative to other currencies increases expenses of our foreign subsidiaries when they are translated into U.S. dollars in our consolidated statements of operations. Likewise, a strengthening U.S. dollar relative to other currencies, including the renminbi or Yen, reduces revenue of our foreign subsidiaries upon translation and consolidation. Exchange rates are subject to significant and rapid fluctuations, and therefore we cannot predict the prospective impact of exchange rate fluctuations. Although we engage in foreign currency hedging activity, we may be unable to hedge all of our foreign currency risk, which could have a negative impact on our results of operations.

Uncertainty in the global economy, and its potential impact on the semiconductor and electronics industries in particular, may negatively affect our business, operating results and financial condition.

Uncertainty caused by the recent challenging global economic conditions, including due to the effects of the COVID-19 pandemic, could lead some of our customers to postpone their decision-making, decrease their spending and/or delay their payments to us. Such caution by customers could, among other things, limit our ability to maintain or increase our sales or recognize revenue from committed contracts. Outside of a slowdown in customer commitments in our Software Integrity segment, we have not seen evidence of impacts on customer orders from the COVID-19 pandemic to date.

We cannot predict the stability of the economy as a whole or the industries in which we operate. Further economic instability could adversely affect the banking and financial services industry and result in credit downgrades of the banks we rely on for foreign currency forward contracts, credit and banking transactions, and deposit services, or cause them to default on their obligations. There is uncertainty regarding how proposed, contemplated or future changes to the complex laws and regulations governing our industry, the banking and financial services industry, and the economy could affect our business. In addition, economic conditions could deteriorate in the future, and, in particular, the semiconductor and electronics industries could fail to grow, including as the result of any disruption of international trade relationships or the effects of the COVID-19 pandemic. In the event of future improvements in economic conditions for our customers, the positive impact on our revenues and financial results may be deferred due to our business model. Any of the foregoing could cause adverse effects on our business, operating results and financial condition, and could cause our stock price to decline.

45

Our operating results may fluctuate in the future, which may adversely affect our stock price.

Our operating results are subject to quarterly and annual fluctuations, which may adversely affect our stock price. Our historical results should not be viewed as indicative of our future performance due to these periodic fluctuations.

Many factors may cause our revenue or earnings to fluctuate, including:

• Changes in demand for our products—especially products, such as hardware, generating upfront revenue—due to fluctuations in demand for our customers’ products and due to constraints in our customers’ budgets for research and development and EDA products and services;

• Changes in demand for our products due to customers reducing their expenditures, whether as a cost-cutting measure or a result of their insolvency or bankruptcy, and whether due to the COVID-19 pandemic or other reasons;

• Product competition in the EDA industry, which can change rapidly due to industry or customer consolidation and technological innovation;

• Our ability to innovate and introduce new products and services or effectively integrate products and technologies that we acquire;

• Failures or delays in completing sales due to our lengthy sales cycle, which often includes a substantial customer evaluation and approval process because of the complexity of our products and services;

• Our ability to implement effective cost control measures;

• Our dependence on a relatively small number of large customers, and on such customers continuing to renew licenses and purchase additional products from us, for a large portion of our revenue;

• Changes to the amount, composition and valuation of, and any impairments to or write-offs of, our inventory;

• Changes in the mix of our products sold, as increased sales of our products with lower gross margins, such as our hardware products, may reduce our overall margins;

• Expenses related to our acquisition and integration of businesses and technology;

• Changes in tax rules, as well as changes to our effective tax rate, including the tax effects of infrequent or unusual transactions and tax audit settlements;

• Delays, increased costs or quality issues resulting from our reliance on third parties to manufacture our hardware products, which includes a sole supplier for certain hardware components;

• Natural variability in the timing of IP drawdowns, which can be difficult to predict;

• General economic and political conditions that affect the semiconductor and electronics industries, such as disruptions to international trade relationships, including tariffs, export licenses, or other trade barriers affecting our or our suppliers' products, as well as impacts due to the COVID-19 pandemic; and

• Changes in accounting standards, which may impact the way we recognize our revenue and costs and impact our earnings.

The timing of revenue recognition may also cause our revenue and earnings to fluctuate. The timing of revenue recognition is affected by factors that include:

• Cancellations or changes in levels of orders or the mix between upfront products revenue and time-based products revenue;

• Delay of one or more orders for a particular period, particularly orders generating upfront products revenue, such as hardware;

46

• Delay in the completion of professional services projects that require significant modification or customization and are accounted for using the percentage of completion method;

• Delay in the completion and delivery of IP products in development as to which customers have paid for early access;

• Customer contract amendments or renewals that provide discounts or defer revenue to later periods;

• The levels of our hardware and IP revenues, which are recognized upfront and are primarily dependent upon our ability to provide the latest technology and meet customer requirements; and

• Changes in our revenue recognition model.

These factors, or any other factors or risks discussed herein, could negatively impact our revenue or earnings and cause our stock price to decline. Additionally, our results may fail to meet or exceed the expectations of securities analysts and investors, or such analysts may change their recommendation regarding our stock, which could cause our stock price to decline. Our stock price has been, and may continue to be, volatile, which may make it more difficult for our stockholders to sell their shares at a time or a price that is favorable to them.

We operate in highly competitive industries, and if we do not continue to meet our customers’ demand for innovative technology at lower costs, our products may become uncompetitive and obsolete, and our business and financial condition may be harmed.

In our Semiconductor & System Design segment, we compete against EDA vendors that offer a variety of products and services, such as Cadence Design Systems, Inc. and Mentor Graphics Corporation (now part of Siemens AG). We also compete with other EDA vendors, including new entrants to the marketplace, that offer products focused on one or more discrete phases of the IC design process. Moreover, our customers internally develop design tools and capabilities that compete with our products, including internal designs that compete with our IP products. In the area of IP products, we compete against numerous other IP providers as well as our customers' internally developed IP.

In our Software Integrity segment, we compete with numerous other solution providers, many of which focus on specific aspects of software security or quality analysis. We also compete with frequent new entrants, which include start-up companies and more established software companies.

The industries in which we operate are highly competitive and the demand for our products and services is dynamic and depends on a number of factors, including demand for our customers’ products, design starts and our customers’ budgetary constraints. Technology in these industries evolves rapidly and is characterized by frequent product introductions and improvements as well as changes in industry standards and customer requirements. Semiconductor device functionality requirements continually increase while feature widths decrease, substantially increasing the complexity, cost and risk of chip design and manufacturing. At the same time, our customers and potential customers continue to demand an overall lower total cost of design, which can lead to the consolidation of their purchases with one vendor. In order to succeed in this environment, we must successfully meet our customers’ technology requirements and increase the value of our products, while also striving to reduce their overall costs and our own operating costs.

We compete principally on the basis of technology, product quality and features (including ease-of-use), license or usage terms, post-contract customer support, interoperability among products, and price and payment terms. Specifically, we believe the following competitive factors affect our success:

• Our ability to anticipate and lead critical development cycles and technological shifts, innovate rapidly and efficiently, improve our existing software and hardware products, and successfully develop or acquire such new products;

• Our ability to offer products that provide both a high level of integration into a comprehensive platform and a high level of individual product performance;

• Our ability to enhance the value of our offerings through more favorable terms such as expanded license usage, future purchase rights, price discounts and other differentiating rights, such as multiple tool copies, post-contract customer support, “re-mix” rights that allow customers to

47

exchange the software they initially licensed for other Synopsys products, and the ability to purchase pools of technology;

• Our ability to compete on the basis of payment terms; and

• Our ability to provide engineering and design consulting for our products.

If we fail to successfully manage these competitive factors, fail to successfully balance the conflicting demands for innovative technology and lower overall costs, or fail to address new competitive forces, our business and financial condition will be adversely affected.

Cybersecurity threats or other security breaches could compromise sensitive information belonging to us or our customers and could harm our business and our reputation, particularly that of our security testing solutions.

We store sensitive data, including intellectual property, our proprietary business information and that of our customers, and confidential employee information, in our data centers and on our networks. Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions that could result in unauthorized disclosure or loss of sensitive information. As a result of the COVID-19 pandemic and shelter-in-place orders, most of our employees in affected areas are working remotely, which magnifies the importance of the integrity of our remote access security measures.

For example, we discovered unauthorized third-party access to our products and product license files hosted on our SolvNet customer license and product delivery system in 2015. We determined that no customer project or design data had been accessed. No personally identifiable information or payment card information is stored on the system. While we identified and closed the method used to gain access, it is possible that our security measures may be circumvented again in the future, and such a breach could harm our business and reputation. The techniques used to obtain unauthorized access to networks, or to sabotage systems, change frequently and generally are not recognized until launched against a target. We may be unable to anticipate these techniques or to implement adequate preventative measures. Furthermore, in the operation of our business we also use third-party vendors that store certain sensitive data, including confidential information about our employees, and these third parties are subject to their own cybersecurity threats. While our standard vendor terms and conditions include provisions requiring the use of appropriate security measures to prevent unauthorized use or disclosure of our data, as well as other safeguards, a breach may still occur. Any security breach of our own or a third-party vendor’s systems could cause us to be non-compliant with applicable laws or regulations, subject us to legal claims or proceedings, disrupt our operations, damage our reputation, and cause a loss of confidence in our products and services, any of which could adversely affect our business.

Our software products, including our hosted solutions as well as our software security and quality testing solutions, may also be vulnerable to cyber attacks. An attack could disrupt the proper functioning of our software, cause errors in the output of our customers’ work, allow unauthorized access to our or our customers’ proprietary information, and other destructive outcomes. As a result, our reputation could suffer, customers could stop buying our products, we could face lawsuits and potential liability, and our financial performance could be negatively impacted.

We offer software security and quality testing solutions. If we fail to identify new and increasingly sophisticated methods of cyber attacks, or fail to invest sufficient resources in research and development regarding new threat vectors, our security testing products and services may fail to detect vulnerabilities in our customers’ software code. An actual or perceived failure to identify security flaws may harm the perceived reliability of our security testing products and services, and could result in a loss of customers or sales, or an increased cost to remedy a problem. Furthermore, our growth and recent acquisitions in the software security and quality testing space may increase our visibility as a security-focused company and may make us a more attractive target for attacks on our own information technology infrastructure. Successful attacks could damage our reputation as a security-focused company.

If we fail to protect our proprietary technology, our business will be harmed.

Our success depends in part upon protecting our proprietary technology. Our efforts to protect our technology may be costly and unsuccessful. We rely on agreements with customers, employees and other third-parties as well as intellectual property laws worldwide to protect our proprietary technology. These agreements may be breached, and we may not have adequate remedies for any breach. Additionally, despite our measures to prevent piracy, other

48

parties may attempt to illegally copy or use our products, which could result in lost revenue. Some foreign countries do not currently provide effective legal protection for intellectual property and our ability to prevent the unauthorized use of our products in those countries is therefore limited. Our trade secrets may also be stolen, otherwise become known, or be independently developed by competitors.

We may need to commence litigation or other legal proceedings in order to:

• Assert claims of infringement of our intellectual property;

• Defend our products from piracy;

• Protect our trade secrets or know-how; or

• Determine the enforceability, scope and validity of the propriety rights of others.

If we do not obtain or maintain appropriate patent, copyright or trade secret protection, for any reason, or cannot fully defend our intellectual property rights in certain jurisdictions, our business and operating results would be harmed. In addition, intellectual property litigation is lengthy, expensive and uncertain. Legal fees related to such litigation will increase our operating expenses and may reduce our net income.

We may not be able to realize the potential financial or strategic benefits of the acquisitions we complete, or find suitable target businesses and technology to acquire, which could hurt our ability to grow our business, develop new products or sell our products.

Acquisitions and strategic investments are an important part of our growth strategy. We have completed a significant number of acquisitions in recent years. We expect to make additional acquisitions and strategic investments in the future, but we may not find suitable acquisition or investment targets or we may not be able to consummate desired acquisitions or investments due to unfavorable credit markets, commercially unacceptable terms, or other risks, which could harm our operating results. Acquisitions and strategic investments are difficult, time-consuming, and pose a number of risks, including:

• Potential negative impact on our earnings per share;

• Failure of acquired products to achieve projected sales;

• Problems in integrating the acquired products with our products;

• Difficulties entering into new markets in which we are not experienced or where competitors may have stronger positions;

• Potential downward pressure on operating margins due to lower operating margins of acquired businesses, increased headcount costs and other expenses associated with adding and supporting new products;

• Difficulties in retaining and integrating key employees;

• Substantial reductions of our cash resources and/or the incurrence of debt;

• Failure to realize expected synergies or cost savings;

• Difficulties in integrating or expanding sales, marketing and distribution functions and administrative systems, including information technology and human resources systems;

• Dilution of our current stockholders through the issuance of common stock as part of the merger consideration;

• Difficulties in negotiating, governing and realizing value from strategic investments;

• Assumption of unknown liabilities, including tax and litigation, and the related expenses and diversion of resources;

• Disruption of ongoing business operations, including diversion of management’s attention and uncertainty for employees and customers, particularly during the post-acquisition integration process;

49

• Potential negative impacts on our relationships with customers, distributors and business partners;

• Exposure to new operational risks, regulations, and business customs to the extent acquired businesses are located in regions where we are not currently conducting business;

• The need to implement controls, processes and policies appropriate for a public company at acquired companies that may have lacked such controls, processes and policies;

• Negative impact on our net income resulting from acquisition or investment-related costs; and

• Requirements imposed by government regulators in connection with their review of an acquisition, including required divestitures or restrictions on the conduct of our business or the acquired business.

If we do not manage the foregoing risks, the acquisitions or strategic investments that we complete may have an adverse effect on our business and financial condition.

We pursue new product and technology initiatives from time to time, and if we fail to successfully carry out these initiatives, our business, financial condition, or results of operations could be adversely impacted.

As part of the evolution of our business, we have made substantial investments to develop new products and enhancements to existing products through our acquisitions and research and development efforts. If we are unable to anticipate technological changes in our industry by introducing new or enhanced products in a timely and cost-effective manner, or if we fail to introduce products that meet market demand, we may lose our competitive position, our products may become obsolete, and our business, financial condition or results of operations could be adversely affected.

Additionally, from time to time, we invest in expansion into adjacent markets, including software security and quality testing solutions. Although we believe these solutions are complementary to our EDA tools, we have less experience and a more limited operating history in offering software quality testing and security products and services, and our efforts in this area may not be successful. Our success in these new markets depends on a variety of factors, including the following:

• Our ability to attract a new customer base, including in industries in which we have less experience;

• Our successful development of new sales and marketing strategies to meet customer requirements;

• Our ability to accurately predict, prepare for, and promptly respond to technological developments in new fields, including, in the case of our software quality testing and security tools and services, identifying new security vulnerabilities in software code and ensuring support for a growing number of programming languages;

• Our ability to compete with new and existing competitors in these new industries, many of which may have more financial resources, industry experience, brand recognition, relevant intellectual property rights, or established customer relationships than we currently do, and could include free and open source solutions that provide similar software quality testing and security tools without fees;

• Our ability to skillfully balance our investment in adjacent markets with investment in our existing products and services;

• Our ability to attract and retain employees with expertise in new fields;

• Our ability to sell and support consulting services at profitable margins; and

• Our ability to manage our revenue model in connection with hybrid sales of licensed products and consulting services.

Difficulties in any of our new product development efforts or our efforts to enter adjacent markets, including delays or disruptions as a result of the COVID-19 pandemic, could adversely affect our operating results and financial condition.

50

We may have to invest more resources in research and development than anticipated, which could increase our operating expenses and negatively affect our operating results.

We devote substantial resources to research and development. New competitors, technological advances in the semiconductor industry or by competitors, our acquisitions, our entry into new markets, or other competitive factors may require us to invest significantly greater resources than we anticipate. If we are required to invest significantly greater resources than anticipated without a corresponding increase in revenue, our operating results could decline. Additionally, our periodic research and development expenses may be independent of our level of revenue, which could negatively impact our financial results. Finally, there can be no guarantee that our research and development investments will result in products that create additional revenue.

Product errors or defects could expose us to liability and harm our reputation and we could lose market share.

Software products frequently contain errors or defects, especially when first introduced, when new versions are released, or when integrated with technologies developed by acquired companies. Product errors, including those resulting from third-party suppliers, could affect the performance or interoperability of our products, could delay the development or release of new products or new versions of products and could adversely affect market acceptance or perception of our products. In addition, any allegations of manufacturability issues resulting from use of our IP products could, even if untrue, adversely affect our reputation and our customers’ willingness to license IP products from us. Any such errors or delays in releasing new products or new versions of products or allegations of unsatisfactory performance could cause us to lose customers, increase our service costs, subject us to liability for damages and divert our resources from other tasks, any one of which could materially and adversely affect our business and operating results.

Our hardware products, which primarily consist of prototyping and emulation systems, subject us to distinct risks.

The growth in sales of our hardware products subjects us to several risks, including:

• Increased dependence on a sole supplier for certain hardware components, which may reduce our control over product quality and pricing and may lead to delays in production and delivery of our hardware products, should our supplier fail to deliver sufficient quantities of acceptable components in a timely fashion;

• Increasingly variable revenue and decreasingly accurate revenue forecasts, due to fluctuations in hardware revenue, which is recognized upfront upon shipment, as opposed to most sales of software products for which revenue is recognized over time;

• Potential reductions in overall margins, as the gross margin for our hardware products is typically lower than those of our software products;

• Longer sales cycles, which create risks of insufficient, excess or obsolete inventory and variations in inventory valuation, which can adversely affect our operating results;

• Decreases or delays in customer purchases in favor of next-generation releases, which may lead to excess or obsolete inventory or require us to discount our older hardware products;

• Longer warranty periods than those of our software products, which may require us to replace hardware components under warranty, thus increasing our costs; and

• Potential impacts on our supply chain due to the effects of the COVID-19 pandemic.

Changes in United States Generally Accepted Accounting Principles (U.S. GAAP) could adversely affect our financial results and may require significant changes to our internal accounting systems and processes.

We prepare our consolidated financial statements in conformity with U.S. GAAP. These principles are subject to interpretation by the Financial Accounting Standards Board (FASB), the Securities and Exchange Commission (SEC) and various bodies formed to interpret and create appropriate accounting principles and guidance.

51

The FASB periodically issues new accounting standards on a variety of topics, including, for example, revenue recognition and accounting for leases. For information regarding new accounting standards, please refer to Note 19 of Notes to Unaudited Condensed Consolidated Financial Statements under the heading "Effect of New Accounting Pronouncements." These and other such standards generally result in different accounting principles, which may significantly impact our reported results or could result in variability of our financial results. For example, the new revenue recognition standard became applicable to us at the beginning of fiscal 2019 and there is an increased volatility in our total revenue with less predictability than the prior accounting standard.

Our results could be adversely affected by a change in our effective tax rate as a result of tax law changes and related new or revised guidance and regulations, changes in our geographical earnings mix, unfavorable government reviews of our tax returns, material differences between our forecasted and actual annual effective tax rates, future changes to our tax structure, or by evolving enforcement practices.

Our operations are subject to income and transaction taxes in the United States and in multiple foreign jurisdictions. Because we have a wide range of statutory tax rates in the multiple jurisdictions in which we operate, any changes in our geographical earnings mix, including those resulting from our intercompany transfer pricing or from changes in the rules governing transfer pricing, could materially impact our effective tax rate. Furthermore, a change in the tax law of the jurisdictions where we do business, including an increase in tax rates, an adverse change in the treatment of an item of income or expense or limitations on our ability to utilize tax credits, could result in a material increase in our tax expense and impact our financial position and cash flows. For example, in May 2020, the State of California proposed suspending certain corporate research and development tax credits for three years in response to the fiscal impact of the COVID-19 pandemic, which could result in an increase in our tax expense if enacted.

On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act (Tax Act), which significantly changed prior U.S. tax law and includes numerous provisions that affect our business. The Tax Act includes certain new provisions that began to affect our income from foreign operations in the first quarter of fiscal 2019. Since the beginning of fiscal 2019, the U.S. Treasury Department has issued proposed regulations that could have a material impact on our ability to claim certain tax benefits related to the Tax Act. While we continue to evaluate the potential impact on our estimated annual tax rate, certain of these regulations have not been finalized and are subject to change. As additional regulations and guidance evolve with respect to the Tax Act, and as we gather more information and perform more analysis, our results may materially differ from previous estimates, and those differences may materially affect our financial position. Accounting for certain of these provisions requires the exercise of significant judgment.

Further changes in the tax laws of foreign jurisdictions could arise as a result of the Programme of Work to Develop a Concensus Solution to the Tax Challenges Arising from the Digitalization of the Economy (Programme of Work) agreement by the Organisation for Economic Co-operation and Development (OECD), which represents a coalition of member countries, including the United States. The Programme of Work is evaluating potential changes to numerous long-standing tax principles. These changes, if enacted, by various countries in which we do business may increase our taxes in these countries. Changes to these and other areas in relation to international tax reform, including future actions taken by foreign governments in response to the Tax Act, could increase uncertainty and may adversely affect our tax rate and cash flow in future years.

Our income and non-income tax filings are subject to review or audit by the Internal Revenue Service and state, local and foreign taxing authorities. We exercise significant judgment in determining our worldwide provision for income taxes and, in the ordinary course of our business, there may be transactions and calculations where the ultimate tax determination is uncertain. We may also be liable for potential tax liabilities of businesses we acquire, including future taxes payable related to the transition tax on earnings from their foreign operations, if any, under the Tax Act. Although we believe our tax estimates are reasonable, the final determination in an audit may be materially different than the treatment reflected in our historical income tax provisions and accruals. An assessment of additional taxes because of an audit could adversely affect our income tax provision and net income in the periods for which that determination is made.

In July 2017, the Hungarian Tax Authority (HTA) issued a final assessment against our Hungarian subsidiary (Synopsys Hungary) for fiscal years 2011 through 2013. The HTA has applied withholding taxes on certain payments made to affiliates, resulting in an aggregate tax assessment of approximately $25.0 million and interest and penalties of $11.0 million. We paid the tax assessments, penalties and interest in the first quarter of fiscal 2018 as required by law and recorded these amounts as prepaid taxes on our balance sheet. On April 30, 2019, the Hungarian Administrative Court ruled against Synopsys Hungary. We filed an appeal with the Hungarian Supreme

52

Court on July 5, 2019. A Hungarian Supreme Court hearing date set for April 16, 2020 was postponed due to the COVID-19 pandemic. As of April 30, 2020, we have requested but not yet received a new hearing date, which would be granted at the discretion of the Hungarian Supreme Court. For further discussion of the Hungary audit, see Note 17 of Notes to Unaudited Condensed Consolidated Financial Statements under the heading "Non-U.S. Examinations."

We maintain significant deferred tax assets related to certain tax credits. Our ability to use these credits is dependent upon having sufficient future taxable income in the relevant jurisdiction and in the case of foreign tax credits, how such credits are treated under provisions of the Tax Act. Changes in our forecasts of future income could result in an adjustment to the deferred tax asset and a related charge to earnings that could materially affect our financial results.

Liquidity requirements in our U.S. operations may require us to raise cash in uncertain capital markets, which could negatively affect our financial condition.

As of April 30, 2020, approximately 63% of our worldwide cash and cash equivalents balance is held by our international subsidiaries. We intend to meet our U.S. cash spending needs, including the Tax Act provisional transition tax, primarily through our existing U.S. cash balances, ongoing U.S. cash flows, and available credit under our term loan and revolving credit facilities. Should our cash spending needs in the U.S. rise and exceed these liquidity sources, due to the impact of the COVID-19 pandemic or otherwise, we may be required to incur additional debt at higher than anticipated interest rates or access other funding sources, which could negatively affect our results of operations, capital structure or the market price of our common stock.

From time to time we are subject to claims that our products infringe on third-party intellectual property rights.

We are from time to time subject to claims alleging our infringement of third-party intellectual property rights, including patent rights. Under our customer agreements and other license agreements, we agree in many cases to indemnify our customers if our products infringe a third party’s intellectual property rights. Infringement claims can result in costly and time-consuming litigation, require us to enter into royalty arrangements, subject us to damages or injunctions restricting our sale of products, invalidate a patent or family of patents, require us to refund license fees to our customers or to forgo future payments or require us to redesign certain of our products, any one of which could harm our business and operating results.

We may be subject to litigation proceedings that could harm our business.

We may be subject to legal claims or regulatory matters involving stockholder, consumer, employment, customer, supplier, competition, and other issues on a global basis. Litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages or, in cases for which injunctive relief is sought, an injunction prohibiting us from manufacturing or selling one or more products. If we were to receive an unfavorable ruling on a matter, our business and results of operations could be materially harmed. Further information regarding certain of these matters is contained in Part II, Item 1, Legal Proceedings.

We may not be able to continue to obtain licenses to third-party software and intellectual property on reasonable terms or at all, which may disrupt our business and harm our financial results.

We license third-party software and other intellectual property for use in product research and development and, in several instances, for inclusion in our products. We also license third-party software, including the software of our competitors, to test the interoperability of our products with other industry products and in connection with our professional services. These licenses may need to be renegotiated or renewed from time to time, or we may need to obtain new licenses in the future. Third parties may stop adequately supporting or maintaining their technology, or they or their technology may be acquired by our competitors. If we are unable to obtain licenses to these third-party software and intellectual property on reasonable terms or at all, we may not be able to sell the affected products, our customers’ use of the products may be interrupted, or our product development processes and professional services offerings may be disrupted, which could in turn harm our financial results, our customers, and our reputation.

The inclusion of third-party intellectual property in our products can also subject us and our customers to infringement claims. Although we seek to mitigate this risk contractually, we may not be able to sufficiently limit our potential liability. Regardless of outcome, infringement claims may require us to use significant resources and may divert management's attention.

53

Some of our products and technology, including those we acquire, may include software licensed under open source licenses. Some open source licenses could require us, under certain circumstances, to make available or grant licenses to any modifications or derivative works we create based on the open source software. Although we have tools and processes to monitor and restrict our use of open source software, the risks associated with open source usage may not be eliminated and may, if not properly addressed, result in unanticipated obligations that harm our business.

If we fail to timely recruit and retain senior management and key employees, our business may be harmed.

We depend in large part upon the services of key members of our senior management team to drive our future success. If we were to lose the services of any member of our senior management team, our business could be adversely affected. To be successful, we must also attract and retain key technical, sales and managerial employees, including those who join us in connection with acquisitions. There are a limited number of qualified EDA and IC design engineers, and competition for these individuals is intense and has increased. Our employees are often recruited aggressively by our competitors and our customers. Any failure to recruit and retain key technical, sales and managerial employees could harm our business, results of operations and financial condition, and our recruiting and retention efforts may be negatively impacted by restrictions on travel and business activity due to the COVID-19 pandemic. Additionally, efforts to recruit and retain qualified employees could be costly and negatively impact our operating expenses.

We issue equity awards from employee equity plans as a key component of our overall compensation. We face pressure to limit the use of such equity-based compensation due to its dilutive effect on stockholders. If we are unable to grant attractive equity-based packages in the future, it could limit our ability to attract and retain key employees.

Our business is subject to evolving corporate governance and public disclosure regulations that have increased both our compliance costs and the risk of noncompliance, which could have an adverse effect on our stock price.

We are subject to changing rules and regulations promulgated by a number of governmental and self-regulatory organizations, including the SEC, the Nasdaq Stock Market, and the FASB. These rules and regulations continue to evolve in scope and complexity and many new requirements have been created in response to laws enacted by Congress, making compliance more difficult and uncertain. For example, our efforts to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act and other regulations, including "conflict minerals" regulations affecting our hardware products, have resulted in, and are likely to continue to result in, increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities.

There are inherent limitations on the effectiveness of our controls and compliance programs.

Regardless of how well designed and operated it is, a control system can provide only reasonable assurance that its objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Moreover, although we have implemented compliance programs and compliance training for employees, such measures may not prevent our employees, contractors or agents from breaching or circumventing our policies or violating applicable laws and regulations. Failure of our control systems and compliance programs to prevent error, fraud or violations of law could have a material adverse impact on our business.

Our investment portfolio may be impaired by any deterioration of capital markets.

From time to time, our cash equivalent and short-term investment portfolio consists of investment-grade U.S. government agency securities, asset-backed securities, corporate debt securities, commercial paper, certificates of deposit, money market funds, municipal securities and other securities, and bank deposits. Our investment portfolio carries both interest rate risk and credit risk and may be negatively impacted by the economic effects of the COVID-19 pandemic. Fixed rate debt securities may have their market value adversely impacted due to a credit downgrade or a rise in interest rates, while floating rate securities may produce less income than expected if interest rates fall or a credit downgrade occurs. As a result of capital pressures on certain banks, especially in Europe, and the continuing low interest rate environment, some of our financial instruments may become impaired.

54

Our future investment income may fall short of expectations due to changes in interest rates or if the decline in fair value of investments held by us is judged to be other-than-temporary. In addition, we may suffer losses in principal if we are forced to sell securities that decline in market value due to changes in the issuer’s credit quality or changes in interest rates.

In preparing our financial statements we make certain assumptions, judgments and estimates that affect amounts reported in our consolidated financial statements, which, if not accurate, may significantly impact our financial results.

We make assumptions, judgments and estimates for a number of items, including the fair value of financial instruments, goodwill, long-lived assets and other intangible assets, the realizability of deferred tax assets, the recognition of revenue and the fair value of stock awards. We also make assumptions, judgments and estimates in determining the accruals for employee-related liabilities, including commissions and variable compensation, and in determining the accruals for uncertain tax positions, valuation allowances on deferred tax assets, allowances for doubtful accounts, and legal contingencies. These assumptions, judgments and estimates are drawn from historical experience and various other factors that we believe are reasonable under the circumstances as of the date of the consolidated financial statements. Actual results could differ materially from our estimates, and such differences could significantly impact our financial results. In addition, we cannot predict the full impact of the COVID-19 pandemic on our business operations. The uncertainty affects management’s estimates and assumptions, which could result in greater variability in a variety of areas that depend on these estimates and assumptions.

Catastrophic events may disrupt our business and harm our operating results.

Due to the global nature of our business, our operating results may be negatively impacted by catastrophic events throughout the world. We rely on a global network of infrastructure applications, enterprise applications and technology systems for our development, marketing, operational, support and sales activities. A disruption or failure of these systems in the event of a major earthquake, fire, telecommunications failure, cybersecurity attack, terrorist attack, epidemic or pandemic (including the COVID-19 pandemic), or other catastrophic event could cause system interruptions, delays in our product development and loss of critical data and could prevent us from fulfilling our customers’ orders. In particular, foreign sales and our foreign infrastructure are vulnerable to regional or worldwide health conditions, including the effects of the outbreak of contagious diseases such as the COVID-19 pandemic. Moreover, our corporate headquarters, a significant portion of our research and development activities, our data centers, and certain other critical business operations are located in California, near major earthquake faults. A catastrophic event that results in the destruction or disruption of our data centers or our critical business or information technology systems would severely affect our ability to conduct normal business operations and, as a result, our operating results would be adversely affected.

Business Combinations [Abstract]

Business Combinations

Business Combinations

During the second quarter of fiscal 2020, the Company completed an acquisition for an aggregate consideration of $105.7 million; including cash consideration of $75.7 million and $30.0 million equal to the fair value of the Company’s products exchanged in connection with the acquisition.

The consideration of $105.7 million was preliminary allocated to $20.6 million of identifiable intangible assets, $4.2 million of net tangible assets, and $80.9 million in goodwill. The fair value of these intangible assets was estimated using the income method. These transactions are not considered to be material to the Company’s unaudited condensed consolidated statements of operations. The acquisition was attributable to the Semiconductor & System Design reporting segment.

Concurrent to this transaction, the Company executed a design service arrangement and recognized an asset of $10.7 million for the off-market component. The $10.7 million contract asset is expected to be amortized over the contractual period of the agreement of five years.

Other Fiscal 2020 Acquisitions

As of April 30, 2020, the Company completed several other acquisitions for an aggregate cash consideration of $79.8 million, net of cash acquired. The Company does not consider these acquisitions to be material, individually or in the aggregate, to the Company's unaudited condensed consolidated statements of operations. The preliminary purchase allocations are $25.2 million of identifiable intangible assets and $55.9 million in goodwill of which $12.9 million is attributable to the Software Integrity reporting segment. The fair value of these intangible assets and goodwill are estimated using the income method.

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.

Liabilities and Restructuring Charges [Abstract]

Liabilities and Restructuring Charges

Liabilities and Restructuring Charges

In the second quarter of fiscal 2019, the Company initiated a restructuring plan for involuntary and voluntary employee termination and facility closure actions as part of a business reorganization to better position the Company for future growth by reallocating resources to priority areas, and to a lesser extent, eliminating operational redundancy. The total charges under the 2019 restructuring plan were $86.0 million and consisted primarily of severance, termination, and retirement benefits under the 2019 Voluntary Retirement Program (VRP).

During the three and six months ended April 30, 2020, the Company incurred restructuring charges of approximately $29.7 million and $38.4 million, respectively, for involuntary employee termination actions and the VRP related to the 2019 restructuring plan. These charges consisted primarily of severance, termination, and retirement benefits. During the three and six months ended April 30, 2020, the Company made payments of $24.7 million and $30.7 million, respectively, related to the 2019 employee termination actions.

Stock Repurchase Program [Abstract]

Stock Repurchase Program

Stock Repurchase Program

The Company’s Board of Directors (the Board) previously approved a stock repurchase program pursuant to which the Company was authorized to purchase up to $500.0 million of its common stock, and has periodically replenished the stock repurchase program to such amount. The Board replenished the stock repurchase program up to $500.0 million on June 14, 2019. The program does not obligate the Company to acquire any particular amount of common stock, and the program may be suspended or terminated at any time by the Company's Chief Financial Officer or the Board. The Company repurchases shares to offset dilution caused by ongoing stock issuances from existing equity plans for equity compensation awards and issuances related to acquisitions, and when management believes it is a good use of cash. Repurchases are transacted in accordance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended (the Exchange Act) and may be made through any means, including, but not limited to, open market purchases, plans executed under Rule 10b5-1(c) of the Exchange Act and

structured transactions. As of April 30, 2020, $200.0 million remained available for future repurchases under the program.

In December 2019, the Company entered into an accelerated share repurchase agreement (the December 2019 ASR) to repurchase an aggregate of $100.0 million of the Company's common stock. Pursuant to the December 2019 ASR, the Company made a prepayment of $100.0 million to receive initial share deliveries of shares valued at $80.0 million. The remaining balance of $20.0 million was settled in February 2020. Total shares purchased under the December 2019 ASR were approximately 0.7 million shares, at an average purchase price of $149.75 per share.

In February 2020, the Company entered into an accelerated share repurchase agreement (the February 2020 ASR) to repurchase an aggregate of $100.0 million of the Company's common stock. Pursuant to the February 2020 ASR, the Company made a prepayment of $100.0 million to receive initial share deliveries of shares valued at $80.0 million. The remaining balance of $20.0 million was settled in May 2020. Total shares purchased under the February 2020 ASR were approximately 0.7 million shares, at an average purchase price of $140.41 per share.

Stock repurchase activities as well as the reissuance of treasury stock for employee stock-based compensation purposes are as follows:

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Apr. 30, 2020

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 the Company’s operating results and financial position. In addition, the Company has considered the potential impact of the COVID-19 pandemic on the business operations. Although no material impairment or other effects have been identified to date related to the COVID-19 pandemic, there is substantial uncertainty in the nature and degree of its continued effects over time. This uncertainty affects management’s accounting estimates and assumptions, which could result in greater variability in a variety of areas that depend on these estimates and assumptions as additional events and information are known.

Principles of Consolidation

Principles of Consolidation. The unaudited condensed consolidated financial statements include the accounts of the Company and all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Fiscal Year End

Fiscal Year End. The Company’s fiscal year generally ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that approximately every five years, the Company has a 53-week year. When a 53-week year occurs, the Company includes the additional week in the first quarter to realign fiscal quarters with calendar quarters. Fiscal 2020 and 2019 are both 52-week years. Fiscal 2020 will end on October 31, 2020. Fiscal 2019 ended on November 2, 2019. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.

Leases

Leases. In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, "Leases (Topic 842)," which supersedes the previous lease requirements in Topic 840. Topic 842 was subsequently amended by several ASUs. The new guidance requires a lessee to recognize a right-of-use (ROU) asset and a lease liability for most operating leases in the consolidated balance sheets. These ASUs also made minor changes to lessor accounting and aligns key aspects of the lessor accounting model with the new

revenue recognition guidance. The new standard did not have a material impact on the unaudited condensed consolidated financial statements for arrangements in which the Company is the lessor.

The Company adopted Topic 842 at the beginning of fiscal 2020 using the modified retrospective method without restatement of comparative periods. The Company elected the package of practical expedients permitted under the transition guidance, which allows the carryforward of historical assessments about (1) lease classification, (2) whether a contract is or contains a lease, and (3) which costs qualify as initial direct costs for leases that existed prior to the adoption. The Company did not elect either the use of hindsight or land easements practical expedients available in transition.

The adoption of the standard did not have an impact on the Company’s beginning retained earnings, results of operations, or cash flows. The operating lease liabilities equaled the present value of the remaining Topic 840 minimum rental payments for those leases, discounted at the Company’s incremental borrowing rate as of the date of adoption. The ROU assets were measured at the amount of the related lease liabilities plus any prepaid rental payments and less any unamortized lease incentives such as tenant improvement allowances. The Company recognized ROU assets of $475 million and operating lease liabilities of $540 million on the unaudited condensed consolidated balance sheets.

After adoption, the Company determines if a contract is or contains a lease at inception. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make payments arising from the lease. Lease liabilities for operating and finance leases are recognized at the lease commencement date based on the present value of future lease payments over the remaining lease terms. ROU assets are derived from the carrying amount of the related lease liability plus any prepaid lease payments, less any lease incentives such as tenant improvement allowances. The Company primarily uses its incremental borrowing rate, determined as of the lease commencement date, to measure the present value of its future lease payments, as the rate implicit in the lease is generally not readily determinable. The Company uses a benchmark senior unsecured yield curve for debt instruments and considers specific credit quality, market conditions, tenor of lease arrangements, and quality of collateral to determine the incremental borrowing rate.

Operating lease expense is recognized on a straight-line basis over the lease term of each lease. Variable payments, such as for maintenance, property taxes or insurance, are recognized on our unaudited condensed consolidated statements of operations as incurred.

The Company has adopted both (1) the practical expedient to not separate lease from non-lease components and (2) the short-term lease exemption. The Company has elected the practical expedient to not separate lease from non-lease components for all classes of underlying assets and the short-term lease exemption for all classes of underlying assets except real estate leases, with terms 12 months or less.

Revenue Recognition

Revenue Recognition. In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Codification (ASC 606), "Revenue from Contracts with Customers," which the Company adopted in fiscal 2019. See Note 2. Summary of Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended October 31, 2019 for revenue recognition policies under the new revenue guidance ASC 606.

Derivatives

In the first quarter of 2020, the Company adopted ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedge Activities, which amends the hedge accounting recognition and presentation requirements of ASC 815. Pursuant to the provisions of ASU 2017-12, the Company is not required to separately measure and report hedge ineffectiveness, which was previously recorded in Other income (expense), net in our unaudited condensed consolidated statements of operations. Also, prior to the adoption of ASU 2017-12, the forward point components of the Cash Flow hedges were excluded from assessing effectiveness of the hedging relationship and were recorded on the unaudited condensed consolidated statements of operations in other income (expense), net. Upon adoption of ASU 2017-12, the Company presents the related earning impact of the Cash Flow hedges in the same income statement section as the hedged items. Also, adoption of the guidance did not impact opening retained earnings or have a material impact on our financial statements.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

Effective Tax Rate

The Company estimates its annual effective tax rate at the end of each fiscal quarter. The effective tax rate takes into account the Company's 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 presents the provision (benefit) for income taxes and the effective tax rates:

	Three Months Ended   April 30,						Six Months Ended   April 30,
	2020			2019			2020			2019
	(in thousands)
Income before income taxes	$	110,166		$	133,917		$	209,739		$	280,972
Provision (benefit) for income taxes	$	246		$	15,707		$	(4,242	)	$	9,248
Effective tax rate	0.2		%	11.7		%	(2.0		)%	3.3		%

Beginning in the Company's fiscal 2019, the annual statutory federal corporate tax rate is 21%.

The Company’s effective tax rate for the six months ended April 30, 2020 is lower than the statutory federal corporate tax rate of 21.0% primarily due to U.S. federal and California tax research credits, foreign-derived intangible income deduction, excess tax benefits from stock-based compensation, and the realizability of 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.

The Company's effective tax rate decreased in the three months ended April 30, 2020 as compared to the same period in fiscal 2019, primarily due to an increase in excess tax benefits from stock based compensation and inclusion of unrecognized foreign tax benefits for the three months ended April 30, 2019. The Company's effective tax rate decreased in the six months ended April 30, 2020, as compared to the same period in fiscal 2019, primarily due to an increase in excess tax benefits from stock-based compensation and the realization of U.S. foreign tax credits.

The U.S. Treasury Department has issued proposed regulations that could impact the calculation of income taxes. While the Company continues to evaluate the potential impact on its estimated annual tax rate, certain regulations have not been finalized and are subject to change.

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. The Company believes 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 $62 million.

Intra-Entity Transfers of Assets

In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory.” This ASU requires the immediate recognition of current and deferred income tax effects of intra-entity transfers of assets other than inventory. This ASU was adopted on the first day of fiscal 2019. As a result of the adoption, the Company recorded a decrease of approximately $130.5 million in retained earnings as of the beginning of the period of adoption, with a corresponding decrease in prepaid taxes related to the unamortized tax expense attributed to intra-entity transfers of assets other than inventory previously deferred. The Company will recognize the income tax consequences of new intra-entity transfers of assets other than inventory in the consolidated statements of operations in the period when the transaction takes place.

Non-U.S. Examinations

Hungarian Tax Authority

In July 2017, the Hungarian Tax Authority (the HTA) issued a final assessment against the Company’s Hungarian subsidiary (Synopsys Hungary) for fiscal years 2011 through 2013. The HTA has applied withholding taxes on certain payments made to affiliates, resulting in an aggregate tax assessment of approximately $25.0 million and interest and penalties of $11.0 million (at current exchange rates). On August 2, 2017, Synopsys Hungary filed a claim contesting the final assessment with the Hungarian Administrative Court (the Court). In the first quarter of fiscal 2018, Synopsys Hungary paid the assessments, penalties and interest as required by law and recorded these amounts as prepaid taxes on its balance sheet, while continuing its challenge to the assessment through the Court. On April 30, 2019, the Court ruled against Synopsys Hungary. The Court's opinion was received on May 16, 2019 and Synopsys Hungary filed an appeal with the Hungarian Supreme Court on July 5, 2019. In the second quarter of 2019, as a result of the Court's decision, the Company recorded a tax expense due to an unrecognized tax benefit of $17.4 million, which is net of estimated U.S. foreign tax credits for the tax assessments. A Hungarian Supreme Court hearing date set for April 16, 2020 was postponed due to the COVID-19 pandemic. As of April 30, 2020, Synopsys Hungary has requested but not yet received a new hearing date, which would be granted at the discretion of the Hungarian Supreme Court.

In the second quarter of fiscal 2020, the Company reached a final settlement with the HTA for fiscal years 2014 through 2018 and recognized a net $6.9 million in previously unrecognized tax benefits.

National Taxation Bureau of Taipei

In the first quarter of fiscal 2019, the Company reached final settlement with the National Taxation Bureau of Taipei for fiscal year 2017 and recognized $5.5 million in previously unrecognized tax benefits.

The Company is also under examination by the tax authorities in certain other jurisdictions. No material assessments have been proposed in these examinations.

Credit and Term Loan Facilities

Credit and Term Loan Facilities

On November 28, 2016, the Company entered into an amended and restated credit agreement with several lenders (the Credit Agreement) providing for (i) a $650.0 million senior unsecured revolving credit facility (the Revolver) and (ii) a $150.0 million senior unsecured term loan facility (the Term Loan). The Credit Agreement amended and restated the Company’s previous credit agreement dated May 19, 2015, in order to increase the size of the revolving credit facility from $500.0 million to $650.0 million, provide a new $150.0 million senior unsecured term loan facility, and extend the termination date of the revolving credit facility from May 19, 2020 to November 28, 2021. Subject to obtaining additional commitments from lenders, the principal amount of the loans provided under the Credit Agreement may be increased by the Company by up to an additional $150.0 million. The Credit Agreement contains financial covenants requiring the Company to operate within a maximum leverage ratio and maintain a minimum interest coverage ratio, as well as other non-financial covenants. As of April 30, 2020, the Company was in compliance with all financial covenants.

As of April 30, 2020, the Company had $111.4 million outstanding balance, net of debt issuance costs, under the Term Loan, of which $90.0 million was classified as long-term liabilities. Outstanding principal payments under the Term Loan are due as follows:

Fiscal year	(in thousands)
Remainder of fiscal 2020	$	9,376
2021	27,187
2022	75,000
Total	$	111,563

In July 2018, the Company entered into a 220.0 million RMB (approximately $33.0 million) credit agreement with a lender in China to support its facilities expansion. Borrowings bear interest at a floating rate based on the Chinese Central Bank rate plus 10% of such rate. As of April 30, 2020, the Company had $24.4 million outstanding under the agreement.

As of October 31, 2019, the Company had $119.8 million outstanding balance, net of debt issuance costs, under the Term Loan, of which $102.2 million was classified as long-term liabilities. There was no outstanding balance under the Revolver as of October 31, 2019.

There was $100.0 million outstanding balance under the Revolver as of April 30, 2020. The Company expects its borrowings under the Revolver will fluctuate from quarter to quarter. Borrowings bear interest at a floating rate based on a margin over the Company’s choice of market observable base rates as defined in the Credit Agreement. As of April 30, 2020, borrowings under the Term Loan bore interest at LIBOR +1.125% and the applicable interest rate for the Revolver was LIBOR +1.000%. In addition, commitment fees are payable on the Revolver at rates between 0.125% and 0.200% per year based on the Company’s leverage ratio on the daily amount of the revolving commitment.

The carrying amount of the short-term and long-term debt approximates the estimated fair value. These borrowings under the Credit Agreement have a variable interest rate structure and are classified within Level 2 of the fair value hierarchy.

Segment Reporting [Abstract]

Segment Disclosure

Segment Disclosure

Segment reporting is based upon the “management approach,” i.e., how management organizes the Company’s 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. Synopsys’ CODMs are its two Co-Chief Executive Officers.

The Company has 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:

The CODMs do not use total assets by segment to evaluate segment performance or allocate resources. 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 the Company’s products are located. Revenue is defined as revenue from external customers. Revenue related to operations in the United States and other geographic areas were:

Contract Balances

The contract assets indicated below are presented as prepaid and other current assets in the unaudited condensed consolidated balance sheets. The contract assets are transferred to receivables when the rights to invoice and receive payment become unconditional.

Contract balances are as follows:

	As of
	April 30, 2020		October 31, 2019
	(in thousands)
Contract assets	$	193,651	$	210,557
Unbilled receivables	$	40,827	$	38,175
Deferred revenue	$	1,521,664	$	1,302,578

During the six months ended April 30, 2020, the Company recognized $795.9 million of revenue that was included in the deferred revenue balance as of October 31, 2019. During the six months ended April 30, 2019, the Company recognized $674.6 million of revenue that was included in the deferred revenue balance as of October 31, 2018.

Contracted but unsatisfied or partially unsatisfied performance obligations were approximately $4.7 billion as of April 30, 2020, which includes $652.6 million in non-cancellable Flexible Spending Account (FSA) commitments from customers where actual product selection and quantities of specific products or services are to be determined by customers at a later date. The Company has elected to exclude future sales-based royalty payments from the remaining performance obligations. The contracted but unsatisfied or partially unsatisfied performance obligations expected to be recognized over the next 12 months are approximately 57%, with the remainder recognized thereafter.

During the three and six months ended April 30, 2020, the Company recognized $34.2 million and $52.1 million, respectively, from performance obligations satisfied from sales-based royalties earned during the periods. During the three and six months ended April 30, 2019, the Company recognized $28.5 million and $47.3 million, respectively, from performance obligations satisfied from sales-based royalties earned during the periods.

Costs of Obtaining a Contract with Customer

The incremental costs of obtaining a contract with a customer, which consist primarily of direct sales commissions earned upon execution of the contract, are required to be capitalized under ASC 340-40 and amortized over the estimated period of which the benefit is expected to be received. As direct sales commissions paid for renewals are commensurate with the amounts paid for initial contracts, the deferred incremental costs will be recognized over the contract term. Total capitalized direct commission costs as of April 30, 2020 were $94.4 million and are included in other assets in the Company’s unaudited condensed consolidated balance sheets. Amortization of these assets was $14.5 million and $28.3 million during the three and six months ended April 30, 2020, respectively, and are included in sales and marketing expense in the Company’s unaudited condensed consolidated statements of operations. Amortization of these assets was $15.6 million and $28.4 million during the three and six months ended April 30, 2019, respectively, and are included in sales and marketing expense in the Company’s unaudited condensed consolidated statements of operations.

Fair Value Disclosures [Abstract]

Fair Value Measures

Fair Value Measures

Accounting Standards Codification (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, the Company measures the fair value of certain of its assets and liabilities, which include cash equivalents, non-qualified deferred compensation plan assets, and foreign currency derivative contracts.

The Company’s cash equivalents 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.

The Company’s 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.

The Company’s 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.

The Company’s borrowings under its 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 to the Company for debt with similar terms and maturities. See Note 9. Credit and Term Loan Facilities for more information on these borrowings.

Assets/Liabilities Measured at Fair Value on a Non-Recurring Basis

Non-Marketable Equity Securities

Equity investments in privately-held companies, also called non-marketable equity securities, are accounted for using either the alternative method or equity method of accounting.

The non-marketable equity securities are measured and recorded at fair value when an event or circumstance which impacts the fair value of these securities indicates an other-than-temporary decline in value has occurred. In such events, these equity investments would be classified within Level 3 as they are valued using significant unobservable inputs or data in an inactive market, and the valuation requires management judgment due to the absence of market price and inherent lack of liquidity. The Company monitors these investments and generally uses the income approach to assess impairments based primarily on the financial conditions of these companies.

The Company did not recognize any impairment during the three months ended April 30, 2020 and recognized immaterial impairment during the six months ended April 30, 2020. The Company did not recognize any impairment during the three and six months ended April 30, 2019.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

The Company has 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, the Company has condensed or omitted certain information and footnote disclosures it normally includes in its annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). In management’s opinion, the Company has made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary to fairly present its unaudited condensed consolidated balance sheets, results of operations, comprehensive income, stockholders' equity and cash flows. The Company’s 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 Synopsys’ Annual Report on Form 10-K for the fiscal year ended October 31, 2019 as filed with the SEC on December 20, 2019.

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 the Company’s operating results and financial position. In addition, the Company has considered the potential impact of the COVID-19 pandemic on the business operations. Although no material impairment or other effects have been identified to date related to the COVID-19 pandemic, there is substantial uncertainty in the nature and degree of its continued effects over time. This uncertainty affects management’s accounting estimates and assumptions, which could result in greater variability in a variety of areas that depend on these estimates and assumptions as additional events and information are known.

Principles of Consolidation. The unaudited condensed consolidated financial statements include the accounts of the Company and all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Fiscal Year End. The Company’s fiscal year generally ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that approximately every five years, the Company has a 53-week year. When a 53-week year occurs, the Company includes the additional week in the first quarter to realign fiscal quarters with calendar quarters. Fiscal 2020 and 2019 are both 52-week years. Fiscal 2020 will end on October 31, 2020. Fiscal 2019 ended on November 2, 2019. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.

Leases. In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, "Leases (Topic 842)," which supersedes the previous lease requirements in Topic 840. Topic 842 was subsequently amended by several ASUs. The new guidance requires a lessee to recognize a right-of-use (ROU) asset and a lease liability for most operating leases in the consolidated balance sheets. These ASUs also made minor changes to lessor accounting and aligns key aspects of the lessor accounting model with the new

revenue recognition guidance. The new standard did not have a material impact on the unaudited condensed consolidated financial statements for arrangements in which the Company is the lessor.

The Company adopted Topic 842 at the beginning of fiscal 2020 using the modified retrospective method without restatement of comparative periods. The Company elected the package of practical expedients permitted under the transition guidance, which allows the carryforward of historical assessments about (1) lease classification, (2) whether a contract is or contains a lease, and (3) which costs qualify as initial direct costs for leases that existed prior to the adoption. The Company did not elect either the use of hindsight or land easements practical expedients available in transition.

The adoption of the standard did not have an impact on the Company’s beginning retained earnings, results of operations, or cash flows. The operating lease liabilities equaled the present value of the remaining Topic 840 minimum rental payments for those leases, discounted at the Company’s incremental borrowing rate as of the date of adoption. The ROU assets were measured at the amount of the related lease liabilities plus any prepaid rental payments and less any unamortized lease incentives such as tenant improvement allowances. The Company recognized ROU assets of $475 million and operating lease liabilities of $540 million on the unaudited condensed consolidated balance sheets.

After adoption, the Company determines if a contract is or contains a lease at inception. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make payments arising from the lease. Lease liabilities for operating and finance leases are recognized at the lease commencement date based on the present value of future lease payments over the remaining lease terms. ROU assets are derived from the carrying amount of the related lease liability plus any prepaid lease payments, less any lease incentives such as tenant improvement allowances. The Company primarily uses its incremental borrowing rate, determined as of the lease commencement date, to measure the present value of its future lease payments, as the rate implicit in the lease is generally not readily determinable. The Company uses a benchmark senior unsecured yield curve for debt instruments and considers specific credit quality, market conditions, tenor of lease arrangements, and quality of collateral to determine the incremental borrowing rate.

Operating lease expense is recognized on a straight-line basis over the lease term of each lease. Variable payments, such as for maintenance, property taxes or insurance, are recognized on our unaudited condensed consolidated statements of operations as incurred.

The Company has adopted both (1) the practical expedient to not separate lease from non-lease components and (2) the short-term lease exemption. The Company has elected the practical expedient to not separate lease from non-lease components for all classes of underlying assets and the short-term lease exemption for all classes of underlying assets except real estate leases, with terms 12 months or less.

Revenue Recognition. In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Codification (ASC 606), "Revenue from Contracts with Customers," which the Company adopted in fiscal 2019. See Note 2. Summary of Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended October 31, 2019 for revenue recognition policies under the new revenue guidance ASC 606.

Restricted cash. The Company includes amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the consolidated statements of cash flows. All restricted cash is primarily associated with office leases and has no material impact on the Company’s unaudited condensed consolidated statements of cash flows.

The following table provides a reconciliation of cash, cash equivalents and restricted cash included in the unaudited condensed consolidated balance sheets:

	As of
	April 30, 2020		October 31, 2019
	(in thousands)
Cash and cash equivalents	$	856,424	$	728,597
Restricted cash included in Prepaid expenses and other current assets	1,269		1,174
Restricted cash included in Other long-term assets	725		756
Total cash, cash equivalents and restricted cash	$	858,418	$	730,527

Non-marketable equity securities. The Company’s strategic investment portfolio consists of non-marketable equity securities in privately held companies. The investments that the Company have less than 20% equity interests or do not have the ability to exercise significant influence are accounted using the measurement alternative when the fair value of the investment is not readily determinable. Securities accounted for as equity method investments are recorded at cost plus the proportional share of the issuers’ income or loss, which is recorded in the Company’s other income (expense), net. The cost basis of securities sold is based on the specific identification method. See Note 7. Fair Value Measures.

Derivatives

In the first quarter of 2020, the Company adopted ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedge Activities, which amends the hedge accounting recognition and presentation requirements of ASC 815. Pursuant to the provisions of ASU 2017-12, the Company is not required to separately measure and report hedge ineffectiveness, which was previously recorded in Other income (expense), net in our unaudited condensed consolidated statements of operations. Also, prior to the adoption of ASU 2017-12, the forward point components of the Cash Flow hedges were excluded from assessing effectiveness of the hedging relationship and were recorded on the unaudited condensed consolidated statements of operations in other income (expense), net. Upon adoption of ASU 2017-12, the Company presents the related earning impact of the Cash Flow hedges in the same income statement section as the hedged items. Also, adoption of the guidance did not impact opening retained earnings or have a material impact on our financial statements.

The Company recognizes derivative instruments as either assets or liabilities in the unaudited condensed consolidated balance sheets at fair value and provides qualitative and quantitative disclosures about such derivatives. The Company operates internationally and is exposed to potentially adverse movements in foreign currency exchange rates. The Company enters into hedges in the form of foreign currency forward contracts to reduce its exposure to foreign currency rate changes on non-functional currency denominated forecasted transactions and balance sheet positions 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 22 months, the majority of which are short-term. The Company does not use foreign currency forward contracts for speculative or trading purposes. The Company enters into foreign exchange forward contracts with high credit quality financial institutions that are rated ‘A’ or above and to date has not experienced nonperformance by counterparties. In addition, the Company mitigates credit risk in derivative transactions by permitting net settlement of transactions with the same counterparty and anticipates 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 22 months or less. Certain forward contracts are rolled over periodically to capture the full length of exposure to the Company’s 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. The Company expects a majority of the hedge balance in OCI to be reclassified to the statements of operations within the next 12 months.

The Company did not have any gains or losses related to discontinuation of cash flow hedges during the three and six months ended April 30, 2020 and 2019.

Prior to adoption of ASU 2017-12, hedge effectiveness is evaluated monthly using spot rates, with any gain or loss caused by hedging ineffectiveness recorded in other income (expense), net. During the three and six months ended April 30, 2020 and 2019, the amounts recognized in other income (expense) for ineffectiveness and excluded component were immaterial.

Upon adoption of ASU 2017-12, the Company elected to use the forward method to measure hedge effectiveness for its Japanese yen revenue and foreign currency expense cash flow hedges. The Company did not change the process for its backlog cash flow hedges and continues to measure hedging effectiveness on a monthly basis.

Non-designated Hedging Activities

The Company’s 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 the Company’s balance sheet exposure is approximately one month.

The Company also has 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 the Company’s hedging program is to minimize the impact of currency fluctuations on its net income over its fiscal year.

Earnings Per Share [Abstract]

Net Income per Share

Net Income Per Share

The Company computes basic net income per share by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted net income per share reflects the dilution from potential common shares outstanding such as stock options and unvested restricted stock units and awards during the period using the treasury stock method.

The table below reconciles the weighted average common shares used to calculate basic net income per share with the weighted average common shares used to calculate diluted net income per share:

⁽¹⁾ 

These stock options and unvested restricted stock units were anti-dilutive for the respective periods and are excluded in calculating diluted net income per share. While such awards were anti-dilutive for the respective periods, they could be dilutive in the future.

Commitments and Contingencies Disclosure [Abstract]

Contingencies

Contingencies

Legal Proceedings

The Company is subject to routine legal proceedings, as well as demands, claims and threatened litigation that arise in the normal course of its business. The ultimate outcome of any litigation is often uncertain and unfavorable outcomes could have a negative impact on the Company’s results of operations and financial condition. The Company regularly 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 is estimable, the Company accrues 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.

The Company has determined that, except as set forth below, no disclosure of estimated loss is required for a claim against the Company 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 the Company’s Annual Report on Form 10-K for the fiscal year ended October 31, 2019 (the Annual Report). See Note 7. Commitments and Contingencies of the Annual Report for further information.

Tax Matters

The Company undergoes 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 is 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, the Company would accrue a liability for the estimated expense.

In addition to the foregoing, the Company is, from time to time, party to various other claims and legal proceedings in the ordinary course of its business, including with tax and other governmental authorities. See Note 17. Income Taxes for a description of certain of these other matters.
