NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Description of Business

Synopsys, Inc. (Synopsys or the Company) is a global leader in providing software, intellectual property and services used to design integrated circuits and electronic systems. The Company supplies the electronic design automation (EDA) software that engineers use to design, create prototypes for and test integrated circuits, also known as chips. The Company also offers 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 develop the electronic systems that incorporate chips and the software that runs on them. To complement these product offerings, the Company provides technical services to support these solutions and help its customers develop chips and electronic systems. The Company is also a leading provider of software tools that developers use to improve the quality, security and time-to-market of software code in a wide variety of industries, including electronics, financial services, energy, and industrials.

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 (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 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, 2014 as filed with the SEC on December 15, 2014.

Use of Estimates. To prepare financial statements in conformity with 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.

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 2015 and 2014 are both 52-week years. The second fiscal quarters, and first six months, of fiscal 2015 and 2014 ended on May 2, 2015 and May 3, 2014, respectively, and the prior fiscal year ended on November 1, 2014. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.

Subsequent Events. The Company has evaluated subsequent events through the date that these unaudited condensed consolidated financial statements were issued.

Note 4. Financial Assets and Liabilities

Cash equivalents and short-term investments. The Company classifies time deposits and other investments with maturities less than three months as cash equivalents. Debt securities and other investments with maturities longer than three months are classified as short-term investments. The Company’s investments generally have a term of less than three years and are classified as available-for-sale carried at fair value, with unrealized gains and losses included in the unaudited condensed consolidated balance sheet as a component of accumulated other comprehensive income (loss), net of tax. Those unrealized gains or losses deemed other than temporary are reflected in other income (expense), net. The cost of securities sold is based on the specific identification method and realized gains and losses are included in other income (expense), net.

During the first fiscal quarter of 2015, the Company made investments in available-for-sale securities. As of April 30, 2015, the balances of these investments are:

	Cost		Gross Unrealized Gains		Gross Unrealized Losses Less Than 12 Months			Gross Unrealized Losses 12 Months or Longer		Estimated Fair Value(1)

(1) See Note 5. Fair Value Measures for further discussion on fair values of cash equivalents and short-term investments.

As of April 30, 2015, the stated maturities of the Company's short-term investments are:

	Amortized Cost		Fair Value
	(in thousands)
Due in 1 year or less	$	74,812	$	74,818
Due in 1-5 years	61,737		61,761
Total	$	136,549	$	136,579

Non-marketable equity securities. The Company’s strategic investment portfolio consists of non-marketable equity securities in privately-held companies. The securities accounted for under cost method investments are reported at cost net of impairment losses. Securities accounted for under 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. Refer to Note 5. Fair Value Measures.

Derivatives. The Company recognizes derivative instruments as either assets or liabilities in the unaudited condensed consolidated financial statements 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

8

rated ‘A’ or above and to date has not experienced nonperformance by counterparties. Further, the Company 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.

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 effective portion of 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 (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 twelve months.

Hedging effectiveness is evaluated monthly using spot rates, with any gain or loss caused by hedging ineffectiveness recorded in other income (expense), net. The premium/discount component of the forward contracts is recorded to other income (expense), net, and is not included in evaluating hedging effectiveness.

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.

The effects of the changes in the fair values of non-designated forward contracts are summarized as follows:

	Three Months Ended   April 30,					Six Months Ended   April 30,
	2015			2014		2015			2014
	(in thousands)
Gain (loss) recorded in other income (expense), net	$	(235	)	$	330	$	(2,993	)	$	(613	)

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

	As of April 30, 2015			As of October 31, 2014
	(in thousands)
Total gross notional amount	$	702,008		$	793,937
Net fair value	$	(5,436	)	$	(2,455	)

The notional amounts for derivative instruments do not represent the amount of the Company’s exposure to market gain or loss. 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 represents the unaudited condensed consolidated balance sheet location and amount of derivative instrument fair values segregated between designated and non-designated hedge instruments:

Note 5. 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, short-term investments, non-qualified deferred compensation plan assets, and foreign currency derivative contracts.

The Company’s cash equivalents and short-term investments are classified within Level 1 or Level 2 because they are valued using quoted market prices in an active market or alternative independent pricing sources and models utilizing market observable inputs.

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. Refer to Note 7. Credit Facility.

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 cost 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 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. 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 and six months ended April 30, 2015 and 2014, respectively.

As of April 30, 2015, the fair value of the Company’s non-marketable securities was $10.9 million, of which $6.7 million and $4.2 million were accounted for under the cost method and equity method, respectively. As of October 31, 2014, the fair value of non-marketable securities was $10.9 million, of which $6.7 million and $4.2 million were accounted for under the cost method and equity method, respectively.

Note 6. Liabilities and Restructuring Charges

In November 2014, the Company initiated a restructuring program that included a voluntary retirement program (VRP) and a minimal headcount reduction program. The VRP was offered to certain eligible employees in the United States and enrollment for those employees was completed on November 21, 2014. The total cost of the restructuring program was $15.3 million, of which $1.7 million and $14.3 million were paid during the three and six months ended April 30, 2015, respectively. As of April 30, 2015, the remaining balance of $1.0 million is recorded in accounts payable and accrued liabilities in the unaudited condensed balance sheets and will be paid during fiscal 2015.

Total	$	197,529	$	158,972

Note 7. Credit Facility

On February 17, 2012, the Company entered into an agreement with several lenders (the Credit Agreement) providing for (i) a $350.0 million senior unsecured revolving credit facility (the Revolver) and (ii) a $150.0 million senior unsecured term loan facility (the Term Loan). Principal payments on a portion of the Term Loan are due in equal quarterly installments of $7.5 million, with the remainder due when the Credit Agreement expires in October 2016. The Company can elect to make prepayments on the Term Loan, in whole or in part, without premium or penalty. 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 through October 13, 2015. The Credit Agreement contains financial covenants requiring the Company to operate within a maximum leverage ratio and maintain specified levels of cash, as well as other non-financial covenants.

In December 2014, the Company drew down $250.0 million under the Revolver, primarily to finance an accelerated share repurchase agreement. See Note 9. Stock Repurchase Program. During the six monthsended April 30, 2015, the Company made a principal payment of $15.0 million under the Term Loan and $90.0 million under the Revolver. As of April 30, 2015, the Company had a $60.0 million outstanding balance under the Term Loan, of which $30.0 million is classified as long term, and a $160.0 million outstanding balance under the Revolver, which is all considered short term. As of October 31, 2014, the Company had a $75.0 million outstanding balance under the Term Loan, of which $45.0 million was classified as long term, and no outstanding balance under the Revolver. 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, 2015, borrowings under the Term Loan bore interest at LIBOR +1.125% and the applicable interest rate for the Revolver was LIBOR +0.975%. In addition, commitment fees are payable on the Revolver at rates between 0.150% and 0.300% per year based on the Company’s leverage ratio on the daily amount of the revolving commitment.

The Credit Agreement was amended and restated on May 19, 2015. See Note 16. Subsequent Events for details.

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 9. Stock Repurchase Program

The Company’s Board of Directors (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 December 3, 2013, as announced on December 4, 2013. The program does not obligate Synopsys to acquire any particular amount of common stock, and the program may be suspended or terminated at any time by Synopsys’ 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, 2015, $200.3 million remained available for further repurchases under the program.

In December 2014, the Company entered into an accelerated share repurchase agreement (2015 ASR) to repurchase an aggregate of $180.0 million of the Company’s common stock. Pursuant to the 2015 ASR, the Company made a prepayment of $180.0 million and received an initial share delivery of shares valued at $144.0 million with an average purchase price of $43.77 per share. The remaining balance of $36.0 million will be settled within 6 months or earlier upon completion of the repurchase and is included within stockholders' equity as the forward instrument meets the criteria in the Financial Accounting Standards Board (FASB) authoritative guidance for equity treatment. Under the terms of the 2015 ASR, the specific number of shares that the Company ultimately repurchases will be based on the volume-weighted average share price of the Company’s common stock during the repurchase period, less a discount.

Stock repurchase activities are as follow:

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

Note 10. Stock Compensation

The compensation cost recognized in the unaudited condensed consolidated statements of operations for the Company’s stock compensation arrangements was as follows:

	Three Months Ended   April 30,						Six Months Ended   April 30,
	2015			2014			2015			2014
	(in thousands)

Stock compensation expense after taxes	$	15,616		$	14,553		$	31,461		$	28,559

As of April 30, 2015, there was $123.4 million of unamortized share-based compensation expense, which is expected to be amortized over a weighted-average period of approximately 2.5 years.

The intrinsic values of equity awards exercised during the periods are as follows:

	Three Months Ended   April 30,				Six Months Ended   April 30,
	2015		2014		2015		2014
	(in thousands)
Intrinsic value of awards exercised	$	13,114	$	3,648	$	24,631	$	19,847

Note 11. Net Income per Share

The Company computes basic net income per share by dividing net income available to common stockholders 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.

17

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,
	2015		2014		2015		2014
	(in thousands)

Anti-dilutive employee stock-based awards excluded(1)	1,190		1,998		1,859		1,674

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

Note 12. Segment Disclosure

Certain disclosures are required for operating segments, products and services, geographic areas of operation and major customers. 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 the Company’s two Co-Chief Executive Officers.

The Company operates in a single segment to provide software products and consulting services in the EDA software industry. In making operating decisions, the CODMs primarily consider consolidated financial information, accompanied by disaggregated information about revenues by geographic region. Specifically, the CODMs consider where individual “seats” or licenses to the Company’s products are located in allocating revenue to particular geographic areas. Revenue is defined as revenues from external customers. Goodwill is not allocated since the Company operates in one reportable operating segment. Revenues related to operations in the United States and other geographic areas were:

	Three Months Ended   April 30,				Six Months Ended   April 30,
	2015		2014		2015		2014
	(in thousands)
Revenue:
United States	$	286,113	$	243,603	$	563,700	$	477,230
Europe	75,025		71,110		146,908		137,764
Japan	53,242		58,382		114,094		122,702
Asia-Pacific and Other	142,824		144,602		274,545		258,952
Consolidated	$	557,204	$	517,697	$	1,099,247	$	996,648

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

18

One customer accounted for 12.3% and 10.0% of the Company’s unaudited condensed consolidated revenue in the three months ended April 30, 2015 and 2014, respectively, and accounted for 11.8% and 10.8% of the Company’s unaudited condensed consolidated revenue in the six months ended April 30, 2015 and 2014, respectively.

Note 13. Other Income (Expense), net

The following table presents the components of other income (expense), net:

Note 14. Taxes

Effective Tax Rate

The Company estimates its annual effective tax rate at the end of each fiscal quarter. The Company’s estimate takes into account estimations of annual pre-tax income, the geographic mix of pre-tax income and the Company’s interpretations of tax laws and possible outcomes of audits.

The following table presents the provision for income taxes and the effective tax rates:

	Three Months Ended   April 30,						Six Months Ended   April 30,
	2015			2014			2015			2014
	(in thousands)
Income before income taxes	$	83,884		$	68,059		$	160,499		$	139,243
Provision (benefit) for income tax	$	28,288		$	4,742		$	39,714		$	8,230
Effective tax rate	33.7		%	7.0		%	24.7		%	5.9		%

The Company’s effective tax rate for the three and six months ended April 30, 2015 is lower than the statutory federal income tax rate of 35% primarily due to the lower tax rates applicable to its non-U.S. operations and U.S. federal and California research tax credits, partially offset by state taxes, non-deductible stock compensation, and the integration of acquired technologies.

The Company's effective tax rate increased in the three and six months ended April 30, 2015, as compared to the same periods in fiscal 2014, primarily due to the integration of acquired technologies, partially offset by the reinstatement of the U.S. federal research tax credit in the first quarter of fiscal 2015. The effective tax rate for the three and six months ended April 30, 2014 was lower due to the tax benefits of settlements with the Taiwan tax authorities for fiscal 2010 and 2009 and with the IRS for fiscal 2012.

On December 19, 2014, the president signed into law the Tax Increase Prevention Act of 2014 which reinstated the research tax credit retroactive to January 1, 2014 and extended the credit through December 31, 2014. As a result of the new legislation, the Company recognized a benefit in the first quarter of fiscal 2015 related to ten months of fiscal 2014 as well as a benefit to the annual effective tax rate for two months of fiscal 2015. During fiscal 2015 the Company estimates the benefit of the reinstatement of the research tax credit to be approximately $12.4 million.

The Company’s total gross unrecognized tax benefits at April 30, 2015 are $129.9 million exclusive of interest and penalties. If the total gross unrecognized tax benefits at April 30, 2015 were recognized in the future, approximately $129.9 million would decrease the effective tax rate.

19

The timing of the resolution of income tax examinations is highly uncertain as well as the amounts and timing of various tax payments that are part of the settlement process. This could cause large fluctuations in the balance sheet classification of current and non-current assets and liabilities. The Company believes that in the coming twelve months, it is reasonably possible that either certain audits 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 $37 million.

IRS Examinations

In the first quarter of fiscal 2014, the Company reached final settlement with the Examination Division of the IRS on the remaining fiscal 2012 issues and recognized approximately $10.0 million in unrecognized tax benefits.

Non-U.S. Examinations

In the first quarter of fiscal 2015, the Company reached final settlement with the Taiwan tax authorities for fiscal 2012, with regard to certain transfer pricing issues. As a result of the settlement the Company recognized approximately $1.1 million in unrecognized tax benefits.

In the second quarter of fiscal 2014, the Company reached settlements with the Taiwan tax authorities for fiscal 2010 and 2009, with regard to certain transfer pricing issues. As a result of the settlements and the application of the settlements to other open fiscal years, the Company's unrecognized tax benefits decreased by $5.1 million. The net tax benefit resulting from the settlements and the application to other open fiscal years was $3.9 million.

Note 15. Effect of New Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, "Revenue from Contracts with Customers (Topic 606)," which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605).” This ASU requires an entity to recognize revenue when goods are transferred or services are provided to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. This ASU also requires disclosures enabling users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance will be effective for fiscal 2018 unless an extension of the effective date is granted by the FASB, including interim periods within that reporting period, using one of two prescribed retrospective methods. The Company is currently in the process of evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method, nor has it determined the effect of the standard on its ongoing financial reporting.

Note 16. Subsequent Events

On May 19, 2015, the Company entered into an amended and restated credit agreement with several lenders (the Restated Credit Agreement) providing for a $500.0 million senior unsecured revolving credit facility and a $150 million senior unsecured term loan facility. The Restated Credit Agreement amends and restates the Company’s previous Credit Agreement referred to in Note 7, in order to increase the size of the revolving credit facility from $350.0 million to $500.0 million and to extend the termination date of the revolving credit facility from October 14, 2016 to May 19, 2020. The Restated Credit Agreement also replaces a financial covenant requiring the Company to maintain a minimum specified level of cash with a covenant requiring a minimum interest coverage ratio. Otherwise, the terms and conditions of the Restated Credit Agreement are substantially similar to the previous Credit Agreement. The Company's outstanding Revolver and Term Loan borrowings under the previous Credit Agreement, described in Note 7, are carried over under the Restated Credit Agreement. The Company expects its borrowings under the Restated Credit Agreement will fluctuate from quarter to quarter.

Overview

Business Summary

Synopsys is a global leader in providing software, intellectual property and services used to design integrated circuits and electronic systems. We supply the electronic design automation (EDA) software that engineers use to design, create prototypes for and test integrated circuits, also known as chips. We also offer 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 develop the electronic systems that incorporate chips and the software that runs on them. To complement these product offerings, we provide technical services to support our solutions and help our customers develop chips and electronic systems. We are also a leading provider of software tools that developers use to improve the quality, security, and time-to-market of software code in a wide variety of industries, including electronics, financial services, energy, and industrials.

Our EDA and IP customers are generally semiconductor and electronics systems companies. Our solutions help them overcome the challenge of developing increasingly advanced electronics products while reducing their design and manufacturing costs. While our products are an important part of our customers’ development process, our customers’ research and development budget and spending decisions may be affected by their business outlook and their willingness to invest in new and increasingly complex chip designs.

Despite global economic uncertainty, we have maintained profitability and positive cash flow on an annual basis in recent years. We achieved these results not only because of our solid execution, leading technology and strong customer relationships, but also because of our time-based revenue business model. Under this model, a substantial majority of our customers pay for their licenses over time and we typically recognize this revenue over the life of the contract, which averages approximately three years. Time-based revenue, which consists of time-based license, maintenance and service revenue, generally represents approximately 90% of our total revenue. The revenue we recognize in a particular period generally results from selling efforts in prior periods rather than the

21

current period. Due to our business model, 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 quality and security market, which we entered with our acquisition of Coverity, Inc. (Coverity) as discussed below. As we continue to expand our product portfolio and our total addressable market, for instance in IP products, we may experience increased variability in our revenue, though we generally expect time-based revenue to continue to represent approximately 90% of our total revenue. Overall, our business outlook remains solid based on our leading technology, customer relationships, business model, diligent expense management, and acquisition strategy. We believe that these factors will help us continue to successfully execute our strategies.

Acquisition of Coverity

On March 24, 2014, we acquired Coverity, the leading provider of software quality, testing and security tools. We believe this acquisition has enabled us to enter into a new, growing market dedicated to helping companies deliver better software faster, by finding software code defects as the code is being developed rather than at the end of the process. Coverity’s customer base includes Synopsys’ semiconductor and systems customers, albeit different users and budgets, and extends well beyond to software developers such as independent software vendors and companies engaged in e-commerce. We believe the Coverity acquisition has expanded our total addressable market.

Financial Performance Summary

In the second quarter of fiscal 2015, compared to the same period of fiscal 2014:

• Our operating income of $75.9 million was higher by $12.1 million or 19% reflecting the following:

◦ Total revenue of $557.2 million, an increase of $39.5 million or 8%, primarily due to continued growth both organically and through our prior-year acquisitions.

◦ Total cost of revenue and operating expenses of $481.3 million, an increase of $27.4 million or 6%, primarily due to our operational growth and prior-year acquisitions resulting in higher employee-related costs.

• Our net income of $55.6 million was lower by $7.7 million or 12% as the increase in our operating income was more than offset by the increase in our tax provision resulting primarily from the integration of our acquired technologies in fiscal 2015.

We continued to derive more than 90% of our total revenue from time-based revenue.

New Accounting Pronouncements

See Note 15 of the Notes to Unaudited Condensed Consolidated Financial Statements.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial results under the heading “Results of Operations” below are based on our unaudited condensed consolidated financial statements, which we have prepared in accordance with 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.

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 stock compensation;

• Valuation of intangible assets; and

• Income taxes.

Our critical accounting policies and estimates are discussed in Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of our Annual Report on Form 10-K for the fiscal year ended October 31, 2014, filed with the SEC on December 15, 2014.

Results of Operations

Revenue Background

We generate our revenue from the sale of software licenses, maintenance and professional services and to a small extent, hardware products. Software license revenue consists of fees associated with the licensing of our software. Maintenance and service revenue consists of maintenance fees associated with perpetual and term licenses and professional services fees. Hardware revenue consists of FPGA-based emulation and prototyping products.

With respect to software licenses, we utilize three license types:

• Technology Subscription Licenses (TSLs). TSLs are time-based licenses for a finite term, and generally provide the customer limited rights to receive, or to exchange certain quantities of licensed software for, unspecified future technology. We bundle and do not charge separately for post-contract customer support (maintenance) for the term of the license.

• Term licenses. Term licenses are also for a finite term, but do not provide the customer any rights to receive, or to exchange licensed software for, unspecified future technology. Customers purchase maintenance separately for the first year and may renew annually for the balance of the term. The annual maintenance fee is typically calculated as a percentage of the net license fee.

• Perpetual licenses. Perpetual licenses continue as long as the customer renews maintenance plus an additional 20 years. Perpetual licenses do not provide the customer any rights to receive, or to exchange licensed software for, unspecified future technology. Customers purchase maintenance separately for the first year and may renew annually.

For the three software license types, we recognize revenue as follows:

• TSLs. We typically recognize revenue from TSL fees (which include bundled maintenance) ratably over the term of the license period, or as customer installments become due and payable, whichever is later. Revenue attributable to TSLs is reported as “time-based license revenue” in the unaudited condensed consolidated statements of operations.

• Term licenses. We recognize revenue from term licenses in full upon shipment of the software if payment terms require the customer to pay at least 75% of the license fee and 100% of the maintenance fee within one year from shipment and all other revenue recognition criteria are met. Revenue attributable to these term licenses is reported as “upfront license revenue” in the unaudited condensed consolidated statements of operations. For term licenses in which less than 75% of the license fee and 100% of the maintenance fee is payable within one year from shipment, we recognize revenue as customer payments become due and payable. Such revenue is reported as “time-based license revenue” in the unaudited condensed consolidated statements of operations.

• Perpetual licenses. We recognize revenue from perpetual licenses in full upon shipment of the software if payment terms require the customer to pay at least 75% of the license fee and 100% of the maintenance fee within one year from shipment and all other revenue recognition criteria are met. Revenue attributable to these perpetual licenses is reported as “upfront license revenue” in the unaudited condensed consolidated statements of operations. For perpetual licenses in which less than 75% of the license fee and 100% of the maintenance fee is payable within one year from shipment, we recognize revenue as customer installments become due and payable. Such revenue is reported as “time-based license revenue” in the unaudited condensed consolidated statements of operations.

Under current accounting rules and policies, we recognize revenue from orders we receive for software licenses, services and hardware products at varying times. In most instances, we recognize revenue on a TSL software license order over the license term and on a term or perpetual software license order in the quarter in which the license is delivered. The weighted-average license term of the TSLs and term licenses we entered into for the three months ended April 30, 2015 and 2014 was 2.5 and 2.8 years, respectively. Revenue on contracts requiring significant modification or development is accounted for using the percentage of completion method over the period of the development. Revenue on hardware product orders is generally recognized in full at the time the product is shipped. Contingent revenue is recognized if and when the applicable event occurs.

Revenue on maintenance orders is recognized ratably over the maintenance period (normally one year). Revenue on professional services orders is generally recognized after services are performed and accepted by the customer.

23

Our revenue in any period is equal to the sum of our time-based license, upfront license, maintenance and professional services for the period. We derive time-based license revenue largely from TSL orders received and delivered in prior quarters and to a smaller extent due to contracts in which revenue is recognized as customer installments become due and payable and from contingent revenue arrangements. We derive upfront license revenue directly from term and perpetual license and hardware product orders mostly booked and shipped during the period. We derive maintenance revenue largely from maintenance orders received in prior periods since our maintenance orders generally yield revenue ratably over a term of one year. We also derive professional services revenue primarily from orders received in prior quarters, since we recognize revenue from professional services as those services are delivered and accepted or on percentage of completion for arrangements requiring significant modification of our software, and not when they are booked. Our license revenue is sensitive to the mix of TSLs and perpetual or term licenses delivered during a reporting period. A TSL order typically yields lower current quarter revenue but contributes to revenue in future periods. For example, a $120,000 order for a three-year TSL delivered on the last day of a quarter typically generates no revenue in that quarter, but $10,000 in each of the twelve succeeding quarters. Conversely, a $120,000 order for perpetual and term licenses with greater than 75% of the license fee due within one year from shipment typically generates $120,000 in revenue in the quarter the product is delivered, but no future revenue. Additionally, revenue in a particular quarter may also be impacted by perpetual and term licenses in which less than 75% of the license fees and 100% of the maintenance fees are payable within one year from shipment as the related revenue will be recognized as revenue in the period when customer payments become due and payable.

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 a highly competitive EDA market. Customers generally negotiate the total value of the arrangement rather than just unit pricing or volumes.

Total Revenue

	April 30,
	2015		2014		$ Change		% Change
	(dollars in millions)
Three months ended	$	557.2	$	517.7	$	39.5	8	%
Six months ended	$	1,099.2	$	996.6	$	102.6	10	%

Our revenues are subject to fluctuations, primarily due to customer requirements, including payment terms and the timing and value of contract renewals. For example, we experience variability in our quarterly revenue due to factors such as the timing of renewals of maintenance contracts, timing of IP consulting projects and royalties, and certain contracts where revenue is recognized when customer installment payments are due, as well as variability in hardware sales.

The increase in total revenue for the three and six months ended April 30, 2015 compared to the same periods in fiscal 2014 was due to our overall growth and contributions from acquired companies.

Time-Based License Revenue

	April 30,
	2015			2014			$ Change		% Change
	(dollars in millions)
Three months ended	$	447.8		$	424.2		$	23.6	6	%
Percentage of total revenue	80		%	82		%
Six months ended	$	878.9		$	824.3		$	54.6	7	%
Percentage of total revenue	80		%	83		%

The increase in time-based license revenue for the three and six months ended April 30, 2015 compared to the same periods in fiscal 2014 was primarily attributable to an increase in TSL license revenue due to our overall growth, including contributions of revenue from acquired companies.

Upfront License Revenue

	April 30,
	2015			2014			$ Change		% Change
	(dollars in millions)
Three months ended	$	44.3		$	36.3		$	8.0	22	%
Percentage of total revenue	8		%	7		%
Six months ended	$	90.8		$	70.3		$	20.5	29	%
Percentage of total revenue	8		%	7		%

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

The increase in upfront license revenue for the three and six months ended April 30, 2015 compared to the same periods in fiscal 2014 was primarily attributable to an increase in the sale of hardware products and to a lesser extent the sale of perpetual licenses.

As our sales of hardware products grow, we expect upfront license revenue to increase as a percentage of total revenue but remain consistent with our business model in which approximately 90% of our total revenue consists of time-based revenue.

Maintenance and Service Revenue

	April 30,
	2015			2014			$ Change			% Change
	(dollars in millions)
Three months ended
Maintenance revenue	$	16.5		$	19.3		$	(2.8	)	(15	)%
Professional services and other revenue	48.5			37.9			10.6			28	%
Total maintenance and service revenue	$	65.0		$	57.2		$	7.8		14	%
Percentage of total revenue	12		%	11		%
Six months ended
Maintenance revenue	$	34.0		$	38.0		$	(4.0	)	(11	)%
Professional services and other revenue	95.6			64.0			31.6			49	%
Total maintenance and service revenue	$	129.6		$	102.0		$	27.6		27	%
Percentage of total revenue	12		%	10		%

Changes in maintenance revenue are generally attributable to timing of contract renewals and type of contracts that bundle maintenance.

The changes in professional services and other revenue for the three and six months ended April 30, 2015 compared to the same periods in fiscal 2014 were primarily due to the increase in, and timing of, IP consulting projects that are accounted for using the percentage of completion method.

	2015			2014			$ Change			% Change
	(dollars in millions)
Three months ended
Cost of license revenue	$	70.4		$	67.3		$	3.1		5	%
Cost of maintenance and service revenue	29.0			21.1			7.9			37	%
Amortization of intangible assets	25.6			25.7			(0.1		)	—	%
Total	$	125.0		$	114.1		$	10.9		10	%
Percentage of total revenue	22		%	22		%
Six months ended
Cost of license revenue	$	141.1		$	130.1		$	11.0		8	%
Cost of maintenance and service revenue	57.0			41.4			15.6			38	%
Amortization of intangible assets	51.5			48.4			3.1			6	%
Total	$	249.6		$	219.9		$	29.7		14	%
Percentage of total revenue	23		%	22		%

We divide cost of revenue into three categories: cost of license 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 license revenue associated with internal functions providing license delivery and post-customer contract support services. We then allocate these group costs between cost of license revenue and cost of maintenance and service revenue based on license and maintenance and service revenue reported.

Cost of license revenue. Cost of license 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 have 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 training organization, and costs associated with the delivery of our consulting services, such as hotline and on-site support, production services and documentation of maintenance updates.

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, and certain contract rights related to acquisitions.

The increase in cost of revenue for the three months ended April 30, 2015 compared to the same period in fiscal 2014 was primarily due to increases of $7.8 million in costs related to our professional services revenue, $1.0 million in personnel-related costs driven by higher headcount, and $1.0 million in product costs due to increased sales.

The increase in cost of revenue for the six months ended April 30, 2015 compared to the same period in fiscal 2014 was primarily due to increases of $14.1 million in costs related to our professional services revenue, $6.9 million in personnel-related costs driven by higher headcount, $2.6 million in product costs due to increased sales, and $3.1 million in amortization due to the additions of intangible assets from our fiscal 2014 acquisitions and in-process research and development (IPR&D) projects completed since the second quarter of fiscal 2014.

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

Percentage of total revenue	34		%	34		%
Six months ended	$	369.9		$	345.6		$	24.3	7	%
Percentage of total revenue	34		%	35		%

The increase in research and development expenses for the three months ended April 30, 2015 compared to the same period in fiscal 2014 was primarily due to an increase of $5.6 million in personnel-related costs principally as a result of headcount increases, including those from acquisitions, and functionally allocated expenses that were higher by $4.1 million.

The increase in research and development expenses for the six months ended April 30, 2015 compared to the same period in fiscal 2014 was primarily due to an increase of $15.2 million in personnel-related costs principally as a result of headcount increases, including those from acquisitions, and functionally allocated expenses that were higher by $8.0 million.

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

Sales and Marketing

Percentage of total revenue	22		%	22		%
Six months ended	$	226.7		$	220.6		$	6.1	3	%
Percentage of total revenue	21		%	22		%

The increase in sales and marketing expenses for the three months ended April 30, 2015 compared to the same period in fiscal 2014 was primarily due to increases of $1.8 million in variable compensation due to higher sales, $1.9 million in personnel-related costs as a result of headcount increases, and $1.1 million in marketing activities.

The increase in sales and marketing expenses for the six months ended April 30, 2015 compared to the same period in fiscal 2014 was primarily due to increases of $6.9 million in personnel-related costs as a result of headcount increases and $1.0 million in variable compensation due to higher sales, which were partially offset by a $1.3 million decrease in consultant and contractor costs.

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

Percentage of total revenue	7		%	8		%

General and administrative expenses remained flat for the three months ended April 30, 2015 compared to the same period in fiscal 2014. Increases of $6.5 million in facilities and depreciation expenses and $1.4 million in personnel-related costs primarily due to higher headcount were partially offset by higher allocations of $6.7 million in expenses to other functions and a $1.2 million decrease in professional service costs.

The increase in general and administrative expenses for the six months ended April 30, 2015 compared to the same period in fiscal 2014 was primarily due to increases of $12.6 million in facilities and depreciation expenses, $4.0 million in personnel-related costs primarily due to higher headcount, and $4.3 million in other items that were not individually material. The increases were partially offset by higher allocations of $13.6 million in expenses to other functions compared to the same period in fiscal 2014, resulting from increased headcount in other functions and higher spending in allocated costs, and a $4.8 million decrease in professional service costs.

Amortization of intangible assets for the three months ended April 30, 2015 compared to the same period in fiscal 2014 was relatively flat as decreases due to certain fully amortized intangible assets in fiscal 2014 were offset by additions of intangibles assets from our fiscal 2015 acquisitions.

The increase in amortization of intangible assets for the six months ended April 30, 2015 compared to the same period in fiscal 2014 was primarily due to the additions of intangible assets from our fiscal 2014 and 2015 acquisitions and IPR&D projects completed since the second quarter of fiscal 2014. See Note 3 of the Notes to Unaudited Condensed Consolidated Financial Statements for a schedule of future amortization amounts.

Restructuring Charges

In November 2014, we initiated a restructuring program that included a voluntary retirement program (VRP) and a minimal headcount reduction program. The VRP was offered to certain eligible employees in the United States and enrollment for those employees was completed on November 21, 2014. The restructuring program is substantially complete and summarized below.  See Note 6 of the Notes to Unaudited Condensed Consolidated Financial Statements.

The following is a summary of our restructuring activities:

	Balance at Beginning of Period		Costs Incurred		Cash Payments			Balance at End of Period (1)

Other income (expense), net for the three months ended April 30, 2015 was higher compared to the same period in fiscal 2014 primarily due to (1) higher gains in the market value of our executive deferred compensation plan assets and (2) increased foreign currency exchange gains as a result of favorable fluctuations in foreign currency exchange rates.

Other income (expense), net for the six months ended April 30, 2015 was lower compared to the same period in fiscal 2014 primarily due to a gain from the sale of a non-marketable equity investment in the first quarter of fiscal 2014, which was partially offset by (1) increased foreign currency exchange gains in the current period as a result of favorable fluctuations in foreign currency exchange rates and (2) higher interest income in the current period.

Taxes

Our effective tax rate increased in the three and six months ended April 30, 2015, as compared to the same periods in fiscal 2014, primarily due to the integration of acquired technologies, partially offset by the reinstatement of the U.S. federal research tax credit in the first quarter of fiscal 2015. The effective tax rate for the three and six months ended April 30, 2014 was lower due to the tax benefits of settlements with the Taiwan tax authorities for

29

fiscal 2010 and 2009 and with the IRS for fiscal 2012. For further discussion of the provision for income taxes, see Note 14 of the Notes to Unaudited Condensed Consolidated Financial Statements.

Liquidity and Capital Resources

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

As of April 30, 2015, we held an aggregate of $155.6 million in cash, cash equivalents and short-term investments in the United States and an aggregate of $849.9 million in our foreign subsidiaries. Funds held in our foreign subsidiaries are generated from revenue outside North America. At present, such foreign funds are considered to be indefinitely reinvested in foreign countries to the extent of indefinitely reinvested foreign earnings. However, in the event funds from foreign operations were needed to fund cash needs in the U.S. and if U.S. taxes have not already been previously accrued, we would be required to accrue and pay additional U.S. taxes in order to repatriate these funds.

The following sections discuss changes in our unaudited condensed consolidated balance sheets and statements of cash flow, and other commitments of our liquidity and capital resources during the six months ended April 30, 2015.

Cash, Cash Equivalents and Short-Term Investments

	April 30, 2015		October 31, 2014		$ Change			% Change
	(dollars in millions)
Cash and cash equivalents	$	868.8	$	985.8	$	(117.0	)	(12	)%
Short-term investments	$	136.6	$	—	$	136.6		100	%
Total	$	1,005.4	$	985.8	$	19.6		2	%

Cash, cash equivalents and short-term investments increased primarily due to a lower amount of cash paid for acquisitions and intangible assets, higher cash collections, and proceeds from our senior unsecured revolving credit facility, which were partially offset by cash used for stock repurchases under our accelerated stock repurchase agreement entered into in December 2014 (the 2015 ASR), debt repayments, and purchases of property and equipment.

Cash Flows

	April 30,
	2015			2014			$ Change
	(dollars in millions)
Six months ended
Cash provided by operating activities	$	67.7		$	37.9		$	29.8
Cash used in investing activities	(184.3		)	(392.4		)	208.1
Cash provided by financing activities	18.5			157.4			(138.9		)

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 license revenue much sooner than from time-based license revenue, in which the license fee is typically paid either quarterly or annually over the term of the license.

Cash provided by operating activities. Cash provided by operating activities for the six months ended April 30, 2015 was higher compared to the same period in fiscal 2014 primarily due to higher cash collections, which were partially offset by higher disbursements and lower net income.

Cash used in investing activities. Cash used in investing activities for the six months ended April 30, 2015 was lower compared to the same period in fiscal 2014, primarily due to a decrease of $365.7 million in cash paid for acquisitions and intangible assets, net of cash acquired, which was offset by net purchases of short-term investments of $137.0 million.

30

Cash provided by financing activities. Cash provided by financing activities for the six months ended April 30, 2015 was lower compared to the same period in fiscal 2014 primarily due to an increase of $89.9 million for debt repayments and an increase of $100.3 million in cash used for stock repurchases, which were partially offset by an increase of $50.0 million in the proceeds from our senior unsecured revolving credit facility.

Accounts Receivable, net

	April 30, 2015		October 31, 2014		$ Change		% Change
	(dollars in millions)
Accounts Receivable, net	$	338.4	$	326.7	$	11.7	4	%

Our accounts receivable and days sales outstanding (DSO) are primarily driven by our billing and collections activities. Our DSO was 55 days at April 30, 2015, and 55 days at October 31, 2014. Accounts receivable increased primarily due to the timing of billings to customers and collections.

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

	April 30, 2015		October 31, 2014		$ Change			% Change
	(dollars in millions)
Current assets	$	1,545.0	$	1,504.7	$	40.3		3	%
Current liabilities	1,325.0		1,386.8		(61.8		)	(4	)%
Working capital	$	220.0	$	117.9	$	102.1		87	%

Increases in our working capital were primarily due to (1) an increase of $136.6 million in short-term investments, (2) a decrease of $100.7 million in current deferred revenue, (3) a decrease of $96.0 million in accounts payable and accrued liabilities due to timing of disbursements, and (4) an increase of $32.5 million in prepaid and other current assets. These increases in working capital were partially offset by (1) a decrease of $116.9 million in cash and cash equivalents, and (2) an increase of $160.0 million in short-term debt.

Other Commitments—Credit Facility

On February 17, 2012, we entered into an agreement with several lenders (the Credit Agreement) providing for (i) a $350.0 million senior unsecured revolving credit facility (the Revolver) and (ii) a $150.0 million senior unsecured term loan facility (the Term Loan). Principal payments on a portion of the Term Loan are due in equal quarterly installments of $7.5 million, with the remainder due when the Credit Agreement expires in October 2016. We can elect to make prepayments on the Term Loan, in whole or in part, without premium or penalty. 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 through October 13, 2015. The Credit Agreement contains financial covenants requiring us to operate within a maximum leverage ratio and maintain specified levels of cash, as well as other non-financial covenants.

In December 2014, we drew down $250.0 million under the Revolver primarily to finance an accelerated share repurchase agreement. During the six months ended April 30, 2015, we made principal payments of $15.0 million under the Term Loan and $90.0 million under the Revolver. As of April 30, 2015, we had a $60.0 million outstanding balance under the Term Loan, of which $30.0 million is classified as long term, and a $160.0 million outstanding balance under the Revolver, which is all considered short term. As of October 31, 2014, we had a $75.0 million outstanding balance under the Term Loan, of which $45.0 million was classified as long term, and no outstanding balance under the Revolver. 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, 2015, borrowings under the Term Loan bore interest at LIBOR + 1.125% and the applicable interest rate for the Revolver was LIBOR + 0.975%. In addition, commitment fees are payable on the Revolver at rates between 0.150% and 0.300% per year based on our leverage ratio on the daily amount of the revolving commitment.

On May 19, 2015, we entered into an amended and restated credit agreement with several lenders (the Restated Credit Agreement) providing for a $500.0 million senior unsecured revolving credit facility and a $150.0 million senior unsecured term loan facility. The Restated Credit Agreement amends and restates our previous Credit

31

Agreement discussed above in order to increase the size of the revolving credit facility from $350.0 million to $500.0 million and to extend the termination date of the revolving credit facility from October 14, 2016 to May 19, 2020. The Restated Credit Agreement also replaces a financial covenant requiring us to maintain a minimum specified level of cash with a covenant requiring a minimum interest coverage ratio. Otherwise, the terms and conditions of the Restated Credit Agreement are substantially similar to the previous Credit Agreement.  Our outstanding Revolver and Term Loan borrowings under the previous Credit Agreement, described above, are carried over under the Restated Credit Agreement. We expect our borrowings under the Restated Credit Agreement will fluctuate from quarter to quarter.

Other

Our available-for-sale securities as of April 30, 2015 consist of investment-grade U.S. government agency securities, asset-backed securities, corporate debt securities, commercial paper, certificates of deposit, money market funds, and others. We follow an established investment policy and set of guidelines to monitor, manage and limit our exposure to interest rate and credit risk. The policy sets forth credit quality standards and limits our exposure to any one issuer. As of April 30, 2015, we had no direct holdings in structured investment vehicles, sub-prime mortgage-backed securities or collateralized debt obligations and no exposure to these financial instruments through our indirect holdings in money market mutual funds. During the six months ended April 30, 2015, we had no impairment charge associated with our available-for-sale securities portfolio. While we cannot predict future market conditions or market liquidity, we regularly review our investments and associated risk profiles, which we believe will allow us to effectively manage the risks of our investment portfolio.

We proactively manage our cash equivalents and short-term investments 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 and fixed income portfolio 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 4 and 5 of the Notes to Unaudited Condensed Consolidated Financial Statements.

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

Item  3. Quantitative and Qualitative Disclosures about Market Risk

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

Interest Rate Risk. Our exposure to market risk for changes in interest rates has changed since October 31, 2014, due to the addition of our investments in the first quarter of fiscal 2015, which are classified as cash equivalents or short-term investments. The primary objective of our investment activities is to preserve the principal while at the same time maximizing yields without significantly increasing the risk. To achieve this objective, we maintain our portfolio of investments in a mix of tax-exempt and taxable instruments that meet high credit quality standards, as specified in our investment policy. None of these investments are held for trading purposes. Our policy also limits the amount of credit exposure to any one issue, issuer and type of instrument.

As of April 30, 2015, the stated maturities of our short-term investments are:

	Fair Value
	(in thousands)
Due in 1 year or less	$	74,818
Due in 1-5 years	61,761
Total	$	136,579

Actual maturities may differ from the stated maturities because borrowers may have the right to call or prepay certain obligations. These investments are classified as available-for-sale and are recorded on the balance sheet at fair market value with unrealized gains or losses, net of tax, reported as a component of accumulated other comprehensive income (loss), or OCI. The cost of securities sold is based on the specific identification method and realized gains and losses are included in other income (expense), net. Realized gains and losses on sales of available-for-sale securities have not been material in any period presented. The following table presents the amounts of our short-term investments that are subject to interest rate risk by fiscal year of expected maturity and average book yield:

	Maturing in Year Ending October 31,
	2015			2016			2017			2018			Total		Fair Value
	(in thousands)
Short-term investments (variable rate)	$	—		$	1,450		$	2,002		$	—		$	3,452	$	3,452
Average interest rate	—		%	0.54		%	0.54		%	—		%
Short-term investments (fixed rate)	$	61,678		$	64,374		$	5,584		$	1,491		$	133,127	$	133,127
Average interest rate	0.39		%	0.59		%	0.86		%	0.96		%

As of April 30, 2015, our exposure to market risk has not changed materially other than for the short-term investments discussed above, since October 31, 2014. For more information on financial market risks related to changes in interest rates, reference is made to Item 7A. Quantitative and Qualitative Disclosure about Market Risk contained in Part II of our Annual Report on Form 10-K for the fiscal year ended October 31, 2014, filed with the SEC on December 15, 2014.

Item  4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures. As of April 30, 2015, 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, 2015, 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 changes in Synopsys’ internal control over financial reporting during the three months ended April 30, 2015 that have materially affected, or are reasonably likely to materially affect, Synopsys’ internal control over financial reporting.

34

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 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.

Mentor Patent Litigation

We are engaged in complex patent litigation with Mentor Graphics Corporation (Mentor) involving several actions in different forums. We acquired Emulation & Verification Engineering S.A. (EVE) on October 4, 2012. At the time of the acquisition, EVE and EVE-USA, Inc. (collectively, the EVE Parties) were defendants in three patent infringement lawsuits filed by Mentor. Mentor filed suit against the EVE Parties in federal district court in the District of Oregon on August 16, 2010 alleging that EVE’s ZeBu products infringed Mentor’s United States Patent No. 6,876,962. Mentor filed an additional suit in federal district court in the District of Oregon on August 17, 2012 alleging that EVE’s ZeBu products infringed Mentor’s United States Patent No. 6,947,882. Both cases sought compensatory damages, including lost profits and royalties, and a permanent injunction. Mentor also filed a patent infringement lawsuit against Nihon EVE K.K. in Tokyo District Court in 2010 alleging that certain ZeBu products infringe Mentor’s Japanese Patent No. P3,588,324. This case seeks compensatory damages, a permanent injunction and destruction of inventory. On May 15, 2015, the Tokyo District Court ruled that such products did not infringe Mentor's patent.

On September 27, 2012, Synopsys and the EVE Parties filed an action for declaratory relief against Mentor in federal district court in the Northern District of California, seeking a determination that Mentor’s United States Patents Nos. 6,009,531; 5,649,176 and 6,240,376, which were the subject of a patent infringement lawsuit filed by Mentor against EVE in 2006 and settled in the same year, are invalid and not infringed by EVE’s products, and that Mentor is without right or authority to threaten or maintain suit against the plaintiffs on such patents. Mentor asserted patent infringement counterclaims in this action based on the same three patents and sought compensatory damages, including lost profits and royalties, and a permanent injunction. In April 2013, this action was transferred to the federal district court in Oregon and consolidated with the two Mentor lawsuits in that district (the Oregon Action).

The Oregon Action

In the Oregon Action, Synopsys and the EVE Parties further asserted patent infringement counterclaims against Mentor based on Synopsys’ United States Patents Nos. 6,132,109 and 7,069,526, seeking compensatory damages and a permanent injunction. On February 21, 2014, the court granted Mentor’s motion for partial summary judgment based on assignor estoppel, in which Mentor argued Synopsys was barred from challenging the validity of Mentor’s ‘376 patent. In July 2014, the court granted Synopsys’ motion for partial summary judgment on the ‘531 and ‘176 patents, finding that Mentor was barred from asserting those patents under the doctrine of res judicata. The court also granted cross-motions for partial summary judgment brought by both parties, finding that Mentor’s ‘962 and ‘882 patents and Synopsys’ ‘109 and ‘526 patents were non-infringed and/or invalid. As a result of these rulings, the only patent remaining at issue in the Oregon Action is Mentor’s ‘376 patent.

The Oregon Action went to trial on the remaining Mentor patent, and a jury reached a verdict on October 10, 2014 finding that certain features of the ZeBu products infringed the ‘376 patent and assessing damages of approximately $36 million. On March 12, 2015, the court entered an injunction prohibiting certain sales activities relating to the features found by the jury to infringe. Synopsys has released a new version of ZeBu software that does not include such features. Synopsys has appealed from the injunction, and both parties have appealed from the final judgment.

The California Action

On December 21, 2012, Synopsys filed an action for patent infringement against Mentor in federal district court in the Northern District of California, alleging that Mentor’s Veloce products infringe Synopsys’ United States Patents Nos. 5,748,488, 5,530,841, 5,680,318 and 6,836,420 (the California Action). This case seeks compensatory damages and a permanent injunction. The court stayed the action as to the ‘420 patent pending the U.S. Patent and Trademark Office's inter partes review of that patent (discussed below). On January 20, 2015, the court granted Mentor's motion for summary judgment on the '488, '841, and '318 patents, finding that such patents were invalid. Synopsys has appealed the court's ruling.

35

PTO Proceedings

On September 26, 2012, Synopsys filed two inter partes review requests with the U.S. Patent and Trademark Office (the PTO) challenging the validity of Mentor’s ‘376 and ‘882 patents. The PTO granted review of the ‘376 patent and denied review of the ‘882 patent. On February 19, 2014, the PTO issued its final decision in the review of the ‘376 patent, finding some of the challenged claims invalid and some of the challenged claims valid. On April 22, 2014, Synopsys appealed to the Federal Circuit from the PTO’s decision. Mentor filed a cross-appeal on May 2, 2014.

On December 21, 2013, Mentor filed an inter partes review request with the PTO challenging the validity of Synopsys’ ‘420 patent. On June 12, 2014, the PTO granted review of the ‘420 patent.

Item 1A. Risk Factors

We describe our risk factors below.

The continued 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.

While the global economy has shown improvement, there are still uncertainties surrounding the strength of the recovery in many regions. Weakness in the global economy has adversely affected consumer confidence and the growth of the semiconductor industry in recent years, causing semiconductor companies to behave cautiously and focus on their costs, including their research and development budgets, which capture spending on electronic design automation (EDA) products and services. Further uncertainty caused by a global recession could lead some of our customers to postpone their decision-making, decrease their spending and/or delay their payments to us. Continuing caution by semiconductor companies could, among other things, limit our ability to maintain or increase our sales or recognize revenue from committed contracts and in turn could adversely affect our business, operating results and financial condition.

We cannot predict when widespread global economic confidence will be restored. Events such as the timing and execution of the tapering of asset purchases by the U.S. Federal Reserve may continue to drive stock market and interest rate volatility, consumer confidence and product demand. In addition, should further economic instability 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, it could adversely affect our financial results and our business. Accordingly, our future business and financial results are subject to uncertainty, and our stock price is at risk of volatile change. If economic conditions deteriorate in the future, or, in particular, if the semiconductor industry does not grow, our future revenues and financial results could be adversely affected. Conversely, 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.

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

The growth of the EDA industry as a whole, and our business in particular, 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 and their customers. The increasing complexity of designs of systems-on-chips and integrated circuits, 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. Additionally, as the EDA industry matures, consolidation may result 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 intellectual property (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 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.

37

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 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 in the future, but we may not find suitable acquisition targets or we may not be able to consummate desired acquisitions due to unfavorable credit markets, commercially unacceptable terms, or other risks, which could harm our operating results. Acquisitions 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;

• 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;

• Potential negative impact 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 earnings resulting from the application of Accounting Standards Codification (ASC) 805, Business Combinations; 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 these risks, the acquisitions that we complete may have an adverse effect on our business and financial condition.

For example, we have recently acquired providers of software quality, testing, and security tools, including Coverity, Inc. This is a new, though adjacent, technology space for us. The customers for these tools are diverse and include industries with which we do not have experience. We may need to develop new sales and marketing strategies and meet new customer service requirements. At the same time, we will need to compete against new and unfamiliar competitors that may have more financial resources, industry experience or established customer relationships than we do. To successfully develop our software quality, testing, and security offerings, we will need to skillfully balance our investment in the space with investment in our existing products, as well as attract and retain employees with expertise in these new fields. If we fail to do so, we may not realize the expected benefits of our acquisitions, and it may have a negative effect on our earnings and financial condition.

38

Consolidation among our customers, as well as within the industries in which we operate, may negatively impact our operating results.

A number of business combinations, including mergers, asset acquisitions and strategic partnerships, among our customers and in the semiconductor and electronics industries have occurred recently, 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. The loss of customers or reduced customer spending 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, a larger support and service capability, or lower prices, which could negatively impact our business and operating results.

Changes in accounting principles or standards, or in the way they are applied, could result in unfavorable accounting charges or effects and unexpected financial reporting fluctuations, and could adversely affect our reported operating results.

We prepare our consolidated financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP). These principles are subject to interpretation by the Securities and Exchange Commission (SEC) and various bodies formed to interpret and create appropriate accounting principles and guidance. A change in existing principles, standards or guidance can have a significant effect on our reported results, may retroactively affect previously reported results, could cause unexpected financial reporting fluctuations, and may require us to make costly changes to our operational processes.

For example, the Financial Accounting Standards Board (FASB) is currently working together with the International Accounting Standards Board (IASB) to converge certain accounting principles and facilitate more comparable financial reporting between companies that are required to follow U.S. GAAP and those that are required to follow International Financial Reporting Standards (IFRS). In connection with this initiative, the FASB issued a new accounting standard for revenue recognition in May 2014 – Accounting Standards Update (ASU) 2014-09, "Revenue from Contracts with Customers (Topic 606)" – that supersedes nearly all existing U.S. GAAP revenue recognition guidance. Although we are currently in the process of evaluating the impact of ASU 2014-09 on our consolidated financial statements, it could change the way we account for certain of our sales transactions. Adoption of the standard could have a significant impact on our financial statements and may retroactively affect the accounting treatment of transactions completed before adoption.

Further efforts by the FASB and IASB to converge U.S. GAAP and IFRS accounting principles may have a material impact on the way we report financial results in areas including, but not limited to, lease accounting and financial statement presentation. In addition, the SEC may make a determination in the future regarding the incorporation of IFRS into the financial reporting system for U.S. companies. Changes in accounting principles from U.S. GAAP to IFRS, or to converged accounting principles, may have a material impact on our financial statements and may retroactively affect the accounting treatment of previously reported transactions.

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 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;

• 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;

39

• 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;

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

• Changes to our effective tax rate;

• Delays, increased costs or quality issues resulting from our reliance on third parties to manufacture our hardware products; and

• General economic and political conditions that affect the semiconductor and electronics industries.

The timing of revenue recognition may also cause our revenue and earnings to fluctuate, due to factors that include:

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

• Delay of one or more orders for a particular period, particularly orders generating upfront license revenue;

• 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 that customers have paid for early access to;

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

• The levels of our hardware revenues, which are recognized upfront and are primarily dependent upon our ability to provide the latest technology and meet customer requirements, and which may also impact our levels of excess and obsolete inventory expenses; and

• Changes in or challenges to 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.

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

We compete against EDA vendors that offer a variety of products and services, such as Cadence Design Systems, Inc. and Mentor Graphics Corporation. We also compete with other EDA vendors, including frequent new entrants to the marketplace, that offer products focused on one or more discrete phases of the integrated circuit (IC) design process, as well as vendors of IP products and system-level solutions. Moreover, our customers internally develop design tools and capabilities that compete with our products.

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 and 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 products, and successfully develop or acquire 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;

40

• 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 unique rights, such as multiple tool copies, post-contract customer support, “re-mix” rights that allow customers to exchange the software they initially licensed for other Synopsys products, and the ability to purchase pools of technology; and

• Our ability to compete on the basis of payment terms.

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.

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 others and on 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 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 some jurisdictions, our business and operating results would be harmed. In addition, intellectual property litigation is lengthy, expensive and uncertain and legal fees related to such litigation will increase our operating expenses and may reduce our net income.

Our operating results could be adversely affected by an increase in our effective tax rate as a result of tax law changes, changes in our geographical earnings mix, an unfavorable government review of our tax returns, or by material differences between our forecasted and actual annual effective tax rates.

Our operations are subject to income and transaction taxes in the United States and in multiple foreign jurisdictions, with a significant amount of our foreign earnings generated by our subsidiaries organized in Ireland and Hungary. 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, 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 or an adverse change in the treatment of an item of income or expense, could result in a material increase in our tax expense. In addition, U.S. income taxes and foreign withholding taxes have not been provided for on undistributed earnings for certain of our non-U.S. subsidiaries to the extent such earnings are considered to be indefinitely reinvested in the operations of those subsidiaries.

Further changes in the tax laws of foreign jurisdictions could arise as a result of the base erosion and profit shifting (BEPS) project being undertaken by the Organisation for Economic Co-operation and Development (OECD). The OECD, which represents a coalition of member countries, is contemplating changes to numerous long-standing tax principles. These contemplated changes, if finalized and adopted by countries, could increase tax uncertainty and may adversely affect our provision for income taxes. In the U.S., a number of proposals for broad reform of the corporate tax system are under evaluation by various legislative and administrative bodies, but it is not possible to accurately determine the overall impact of such proposals on our effective tax rate at this time.

Our 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 are also liable for potential tax liabilities of businesses we acquire. Although we believe our tax estimates are reasonable, the final determination in an audit may be materially different than the

41

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.

Forecasting our annual effective tax rate is highly complex, as it depends on forward-looking financial projections of our annual income and geographical mix of earnings, our interpretations of the tax laws of numerous jurisdictions, and the possible outcomes of tax audits, among other estimates and assumptions. Some items cannot be forecasted or may be treated as discrete to the future periods when they occur. If our estimates and assumptions prove incorrect, then there may be a material difference between our forecasted and actual effective tax rates, which could have a material impact on our results of operations. In addition, we maintain significant deferred tax assets related to federal research credits and certain state tax credits. Our ability to use these credits is dependent upon having sufficient future taxable income in the relevant jurisdiction. 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.

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 significant, or even any, revenue.

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

We derive more than 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. In addition, we have expanded our non-U.S. operations significantly in the past several years. 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 legal protection of intellectual property rights;

• International economic and political conditions, such as political tensions between countries in which we do business;

• Difficulties in adapting to cultural differences in the conduct of business, which may include business practices that we are prohibited from engaging in 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;

• Government trade restrictions, including tariffs, export licenses, or other trade barriers;

• Additional taxes and penalties; and

• Other factors beyond our control such as natural disasters, terrorism, civil unrest, war and infectious diseases.

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.

In addition, 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. 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 ensure compliance with these laws and regulations, there can be no assurance that our employees, contractors or agents will not violate these laws and regulations.

42

Any violation individually or in the aggregate could have a material adverse effect on our operations and financial condition.

Our financial statements 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 statement of operations. Likewise, a strengthening U.S. dollar relative to other currencies, especially the Japanese 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.

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, 2015, approximately 84.5% of our worldwide cash, cash equivalents and short-term investments balance is held by our international subsidiaries. At present, such foreign funds are considered to be indefinitely reinvested abroad, to the extent they derive from foreign earnings we have indefinitely reinvested in our foreign operations. We intend to meet our U.S. cash spending needs through our existing U.S. cash balances, ongoing U.S. cash flows, and available credit under our term loan and revolving credit facilities. As of April 30, 2015, we had outstanding debt of $60.0 million under our $150 million term loan facility and $160.0 million outstanding debt under our $350 million revolving credit facility. Should our cash spending needs in the U.S. rise and exceed these liquidity sources, 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. For example, we and Emulation & Verification Engineering S.A. (EVE), a company we acquired in October 2012, are party to ongoing patent infringement lawsuits involving Mentor Graphics Corporation. The jury in one of the lawsuits returned a verdict of approximately $36 million in assessed damages against us for patent infringement, and the court in the lawsuit has entered an injunction prohibiting certain sales activities relating to the features found by the jury to infringe. We have appealed the injunction and the final judgment in the case. Further information regarding the EVE lawsuits is contained in Part II, Item 1, Legal Proceedings. In addition, 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.

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 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, 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.

43

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 Coverity 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. Because 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. 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.

We recently began offering software quality and security testing solutions as a result of our acquisition of Coverity. Cybersecurity attacks are increasingly sophisticated, change frequently, and often go undetected until after an attack has been launched. If we fail to identify these new and complex methods of attack, or fail to invest sufficient resources in research and development regarding new threat vectors, our Coverity security testing products 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 Coverity products and could result in a loss of customers, sales, or an increased cost to remedy a problem. Furthermore, our acquisition of Coverity 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.

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, 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 material pending lawsuits, other than ordinary routine litigation incidental to our business, is contained in Part II, Item 1, Legal Proceedings.

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 Synopsys 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. Additionally, efforts to recruit and retain qualified employees could be costly and negatively impact our operating expenses.

We issue stock options and restricted stock units and maintain employee stock purchase 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. In addition, we are required under U.S. GAAP to recognize compensation expense in our results of operations for employee share-based equity compensation under our equity grants and our employee stock purchase plan, which increases the pressure to limit equity-based compensation. These factors may make it more difficult for us to grant attractive equity-based packages in the future, which could limit our ability to attract and retain key employees.

44

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 new 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 the deterioration of capital markets.

Our cash equivalent and short-term investment portfolio currently 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. 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.

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, 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.

45

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 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. 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.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

In December 2014, we entered into an accelerated share repurchase agreement (2015 ASR) to repurchase an aggregate of $180.0 million of our common stock. Pursuant to the 2015 ASR, we made a prepayment of $180.0 million and received an initial share delivery of shares valued at $144.0 million with an average purchase price of $43.77 per share. The remaining balance of $36.0 million will be settled within 6 months or earlier upon completion of the repurchase and is included within stockholders' equity as the forward instrument meets the criteria in the FASB authoritative guidance for equity treatment. Under the terms of the 2015 ASR, the specific number of shares that we ultimately repurchase will be based on the volume-weighted average share price of our common stock during the repurchase period, less a discount.

The table below sets forth information regarding repurchases of Synopsys' common stock by Synopsys during the three months ended April 30, 2015:

Period (1)	Total number of shares purchased	Average price paid per share		Total number of shares purchased as part of publicly announced programs	Maximum dollar value of shares that may yet be purchased under  the programs (1)

This SECOND AMENDMENT TO LEASE AGREEMENT (“Second Amendment”) is made and entered into as of the 2nd day of April, 2015, by and between KR 690 MIDDLEFIELD, LLC, a Delaware limited liability company (“Landlord”), and SYNOPSYS, INC., a Delaware corporation (“Tenant”), with reference to the following facts:

RECITALS :

A.     Landlord (as successor-in-interest to 690 E. Middlefield Road Fee, LLC, a Delaware limited liability company) and Tenant are parties to that certain 690 E. Middlefield Road Lease Agreement dated as of October 14, 2011 (the “Original Lease”), as amended by that certain First Amendment to Lease Agreement dated November 27, 2012 (the “First Amendment”), and that certain Acknowledgement of Commencement of Term dated of even date herewith (the “Commencement Acknowledgement”) (the Lease, the First Amendment, and the Commencement Acknowledgement are hereinafter collectively referred to as the “Lease”), whereby Landlord leases to Tenant and Tenant leases from Landlord the property located at 690 E. Middlefield Road, Mountain View, CA (the “Project”), as more particularly described in the Lease.

B.     Landlord and Tenant desire to amend and modify the Work Letter attached to the Original Lease as Exhibit B (the “Work Letter”), as more particularly set forth below.

AGREEMENT:

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1.    Capitalized Terms. All capitalized terms when used herein shall have the same respective meanings as are given such terms in the Lease unless expressly provided otherwise in this Second Amendment.

2.     Increase in Tenant Allowance. The Tenant Allowance, as set forth in Section 14 (a) of the Work Letter, is hereby increased by One Hundred Ninety-Two Thousand Five Hundred Sixty-Nine Dollars ($192,569.00), from Twenty-One Million Two Hundred Forty-Nine Thousand One Hundred Fifty Dollars ($21,249,150.00) to Twenty-One Million Four Hundred Forty-One Thousand Seven Hundred Nineteen Dollars ($21,441,719.00). Pursuant to the Tenant Expenditure Authorization (“TEA”) attached hereto as Exhibit A, the foregoing increase in the Tenant Allowance is attributable to the transfer of the obligation to construct certain components of Landlord’s Work, as set forth in the TEA as Items COR #22A, #24, #54, #55, and #56 (the “New Tenant’s Work Obligations”), from Landlord to Tenant, less the costs chargeable to Tenant for changes to Landlord’s Work which were previously implemented by Landlord at Tenant’s request (as set forth in the TEA as Items COR #13, #15, #16, #17, #18, #19, #21, #22, #23, #25, #26, #28, #29, #30, #31, #32, #33, #40, #44, #45, #46, and #47 (collectively, the “Additional Landlord’s Work Obligations”)).The New Tenant’s Work Obligations shall constitute part of Tenant’s Work and shall be constructed by Tenant in accordance with the Tenant’s Plans previously approved by Landlord. The parties’ agreement to increase the Tenant Allowance by the amount set forth in this Section 2, and to apply the amounts owing by Tenant to Landlord for the Additional Landlord’s Work Obligations as a credit against the amount of cost savings in the Landlord’s Work due to the New Tenant’s Work Obligations as set forth in the TEA, supersedes the terms of Section 13 of the Work Letter with respect to Tenant’s obligation to pay Landlord directly for Change Orders to Landlord’s Work or the Landlord’s Plans.

3.     Tenant’s Cost. The cost of Tenant’s Work is anticipated to be approximately Thirty-Nine Million Four Hundred Thousand Dollars ($39,400,000.00) (subject to additional change orders), as set forth in that certain Standard Form of Agreement Between Owner and Construction Manager as Constructor dated May 28, 2013 and the change orders which have been approved prior to the date of this Second Amendment, and therefore the cost of Tenant’s Work is anticipated to be less than Forty-Four Million Three Hundred Twenty-One Thousand Thirty Dollars ($44,321,030.00), as referenced in Section 14 (b) of the Work Letter.

4.    Landlord’s and Tenant’s Respective Payment Obligations for Tenant’s Work. In accordance with Section 14(b) of the Work Letter, effective as of the date hereof the following provisions shall apply to Landlord’s and Tenant’s respective obligations to pay for the costs of Tenant’s Work that are allowed to be funded by the Tenant Allowance:

4.1     Landlord shall pay Tenant fifty percent (50%) of the amount of each request submitted by Tenant for disbursement from the Tenant Allowance subject to the terms of Section 14(c) of the Work Letter (provided that such disbursement request qualifies for payment from the Tenant Allowance pursuant to the provisions of the Work Letter) until Landlord has disbursed a total of Seventeen Million Nine Hundred Fifty-Eight Thousand Two Hundred Eighty-One Dollars ($17,958,281.00) for such disbursement requests in the aggregate. The parties acknowledge that Landlord has previously disbursed the full $17,958,281.00 prior to the date of this Second Amendment.

4.2     Tenant shall pay from its own funds (directly to its contractors) fifty percent (50%) of the amount of each request submitted by Tenant for disbursement from the Tenant Allowance subject to the terms of Section 14(c) of the Work Letter (provided that such disbursement request qualifies for payment from the Tenant Allowance pursuant to the provisions of the Work Letter) until Tenant has paid Seventeen Million Nine Hundred Fifty-Eight Thousand Two Hundred Eighty-One Dollars ($17,958,281.00) for such disbursement requests in the aggregate. In no event shall the amounts payable by Tenant under this Section 4.2 be payable by Landlord from the Tenant Allowance. The parties acknowledge that Tenant has previously paid the full $17,958,281.00 prior to the date hereof.

4.3     In view of the fact that Landlord and Tenant have previously paid the full amounts required under Sections 4.1 and 4.2 above, Landlord shall hereafter pay one hundred percent (100%) of the amount of each request submitted by Tenant for disbursement from the Tenant Allowance subject to the terms of Section 14(c) of the Work Letter (provided that such disbursement request qualifies for payment from the Tenant Allowance pursuant to the provisions of the Work Letter), but in no event shall Landlord be required to disburse more than the remaining balance of the Tenant Allowance and any such disbursement from the Tenant Allowance shall be in accordance with Section 14(c) of the Work Letter. Based on the calculations set forth in Sections 2 and 3 above, the remaining balance of the Tenant Allowance following the disbursements and payments set forth in Sections 4.1 and 4.2 above was equal to Three Million Four Hundred Eighty Three Thousand Four Hundred Thirty-Eight Dollars ($3,483,438.00), but as the result of subsequent disbursements by Landlord of the Tenant Allowance, as of the date of this Second Amendment the remaining balance of the Tenant Allowance equals One Million Seven Hundred Nineteen Thousand Nine Hundred Sixty-Eight and 89/100 Dollars ($1,719,968.89).

5.Landlord’s Work. The parties hereby acknowledge and agree that (i) Landlord’s Work (including, without limitation, the Additional Landlord’s Work Obligations, but excluding the components of the originally contemplated Landlord’s Work which now constitute the New Tenant’s Work Obligations) has previously been completed by Landlord, and (ii) notwithstanding any contrary provision of the Lease or the Work Letter, Landlord shall have no obligation to construct the work comprising the New Tenant’s Work Obligations or the corresponding work that would have otherwise been part of Landlord’s Work. Further notwithstanding any contrary provision of the Lease, as amended hereby, or the Work Letter, Landlord shall, at Landlord’s sole cost, following Landlord’s receipt of notice from Tenant on or prior to March 20, 2020, (i) repair any structural defects in the concrete retaining wall located at the Project or cosmetic defects which are unsightly to an unreasonable extent in the event that a structural engineer selected by Landlord and reasonably approved by Tenant determines that such wall has structurally failed or has cosmetic defects which are unsightly to an unreasonable extent, and (ii) repair the decorative scored asphalt at the Project in the event that the deteriorating condition of such asphalt becomes unsightly to an unreasonable extent or there is a reasonable likelihood that such deteriorating condition will cause personal injury (collectively, “Landlord’s Extra Repair Obligations Through 3/20/20”).The parties agree that Landlord’s Extra Repair Obligations Through 3/20/20 shall not apply with respect to any matters for which Tenant fails to notify Landlord in writing on or prior to March 20, 2020. For purposes of Section 1938 of the California Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that the Premises have not undergone inspection by a Certified Access Specialist (CASp).

6.Tenant’s Removal Obligations at End of Lease Term. Notwithstanding any contrary provision of the Work Letter, Landlord hereby reserves the right to require Tenant, at Tenant’s sole cost, to remove the Tenant cafeteria prior to the expiration or sooner termination of the Lease, as amended, and restore such portion of the building to the condition that would have existed pursuant to Landlord’s Plans had such cafeteria not been constructed, upon written notice from Landlord to Tenant prior to the expiration or sooner termination of the Lease, as amended. Further notwithstanding any contrary provision of the Work Letter, Landlord hereby waives the right to require Tenant to remove any items of the New Tenant’s Work Obligations, and except for the Tenant cafeteria, any other items of the Additional Landlord’s Work Obligations, upon the expiration or sooner termination of the Lease.

7.No Brokers. Landlord and Tenant hereby warrant to each other that they have had no dealings with any real estate broker or agent in connection with the negotiation of this Second Amendment, and that they know of no real estate broker or agent who is entitled to a commission in connection with this Second Amendment. Each party agrees to indemnify and defend the other party against and hold the other party harmless from any and all claims, demands, losses, liabilities, lawsuits, judgments, and costs and expenses (including, without limitation, reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of the indemnifying party’s dealings with any real estate broker or agent in connection with this Second Amendment. The terms of this Section 7 shall survive the expiration or earlier termination of the term of the Lease.

8.Utility Billing Information. In connection with any electricity, gas and/or water services to the Premises which Tenant is permitted or required by the Lease to contract for directly with the third-party provider thereof, Tenant shall promptly following written request by Landlord provide Landlord with a copy of the invoices received by Tenant from such third-party providers. Tenant acknowledges that pursuant to California Public Resources Code Section 25402.10 and the regulations adopted pursuant thereto (collectively the “Energy Disclosure Requirements”), Landlord may be required to disclose information concerning Tenant’s energy usage at the Premises to certain third parties, including, without limitation, prospective purchasers, lenders and tenants of the Buildings (the “Tenant Energy Use Disclosure”). Tenant hereby (A) consents to all such Tenant Energy Use Disclosures, and (B) acknowledges that Landlord shall not be required to notify Tenant of any Tenant Energy Use Disclosure. Further, except to the extent of Landlord’s gross negligence in preparing the Tenant Energy Use Disclosure, Tenant hereby releases Landlord from any and all losses, costs, damages, expenses and liabilities relating to, arising out of and/or resulting from any Tenant Energy Use Disclosure. The terms of this Section 8 shall survive the expiration or earlier termination of the Lease, as amended.

9.Governing Law. This Second Amendment shall be construed according to the laws of the State of California, without regard to choice of law provisions thereof.

10.Attorneys’ Fees and Costs. In the event of any action at law or in equity between the parties to enforce any of the provisions of this Second Amendment, any unsuccessful party to such litigation shall pay to the successful party all costs and expenses, including reasonable attorneys’ fees (including costs and expenses incurred in connection with all appeals) incurred by the successful party, and these costs, expenses and attorneys’ fees may be included in and as part of the judgment. A successful party shall be any party who is entitled to recover its costs of suit, whether or not the suit proceeds to final, non-appealable judgment.

11.Counterparts. This Second Amendment may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument, and shall become effective when there exist copies hereof which, when taken together, bear the authorized, original signatures of each of the parties hereto.

12.Conflict; No Further Modification. In the event of any conflict between the Lease and this Second Amendment, the terms of this Second Amendment shall prevail. Except as specifically set forth in this Second Amendment, all of the terms and provisions of the Lease and all exhibits thereto shall remain unmodified and in full force and effect.

13.Waiver. No failure or delay by either party to insist upon the strict performance of any term, condition or covenant of this Second Amendment, or to exercise any right, power or remedy hereunder shall constitute a waiver of the same or any other term of this Second Amendment or preclude such party from enforcing or exercising the same or any such other term, conditions, covenant, right, power or remedy at any later time.

ATTACHMENTS: Appendix

2

The Company has awarded you a Restricted Stock Unit Award (the “Award”) pursuant to Section 7(b) of the Company’s 2006 Employee Equity Incentive Plan (the “Plan”) for the number of Restricted Stock Units as indicated on the first page of this Agreement. Subject to adjustment and the terms and conditions as provided herein and in the Plan, each Restricted Stock Unit shall represent the right to receive one (1) share of Common Stock.

The terms and conditions of your Award, in addition to those set forth above, are as follows.

1.NUMBER OF RESTRICTED STOCK UNITS AND SHARES OF COMMON STOCK.

(a)The number of Restricted Stock Units subject to your Award and the number of shares of Common Stock deliverable with respect to such Restricted Stock Units may be adjusted from time to time for Capitalization Adjustments as described in Section 9(a) of the Plan. You shall receive no benefit or adjustment to your Award with respect to any cash dividend or other distribution that does not result in a Capitalization Adjustment pursuant to Section 9(a) of the Plan; provided, however, that this sentence shall not apply with respect to any shares of Common Stock that are delivered to you in connection with your Award after such shares have been delivered to you.

(b)Any additional Restricted Stock Units, shares of Common Stock, cash or other property that becomes subject to the Award pursuant to this Section 1 shall be subject, in a manner determined by the Board, to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as applicable to the other Restricted Stock Units and Common Stock covered by your Award.

(c)Notwithstanding the provisions of this Section 1, no fractional Restricted Stock Units or rights for fractional shares of Common Stock shall be created pursuant to this Section 1. The Board shall, in its discretion, determine an equivalent benefit for any fractional Restricted Stock Units or fractional shares that might be created by the adjustments referred to in this Section 1.

2.VESTING.

Subject to the limitations contained in this Agreement and the Plan, the Restricted Stock Units shall vest as provided in the vesting schedule set forth above, provided that vesting shall cease upon the termination of your Continuous Service as determined in accordance with Section 11(h) below. Any Restricted Stock Units that have not yet vested shall be forfeited upon the termination of your Continuous Service.

3.DISTRIBUTION OF SHARES OF COMMON STOCK.

(a)    Subject to the provisions of this Agreement and the Plan, in the event one or more Restricted Stock Units vests, the Company shall deliver to you one (1) share of Common Stock for each Restricted Stock Unit that vests, subject to satisfaction of Tax-Related Items as described in Section 10 below. Except as set forth below, the delivery to you of the appropriate

3

number of vested shares of Common Stock shall be made on the applicable vesting date or as soon as practicably possible thereafter. The issuance date determined by this paragraph is referred to as the “Issuance Date.” If the Issuance Date falls on a date that is not a business day, delivery shall instead occur on the next following business day. The form of such delivery (e.g., a stock certificate or electronic entry evidencing such shares) shall be determined by the Company.

(b)    Notwithstanding the foregoing, if (i) the Issuance Date does not occur (1) during an “open window period” applicable to you, as determined by the Company in accordance with the Company’s Insider Trading Policy, or (2) on a date when you are otherwise permitted to sell shares of Common Stock on an established stock exchange or stock market, and (ii) the Company elects, prior to the Issuance Date, (1) not to satisfy the tax withholding obligations described in Section 10 by withholding shares of Common Stock from the shares otherwise due, on the Issuance Date, to you under this Agreement, and (2) not to permit or require you to enter into an immediate sale commitment with a broker-dealer pursuant to Section 10 of this Agreement (including but not limited to a commitment under a previously established Company-approved 10b5-1 trading plan), then such shares shall not be delivered on such Issuance Date and shall instead be delivered on the first business day of the next occurring open window period applicable to you or the next business day when you are not prohibited from selling shares of the Company’s Common Stock in the open public market, but in no event later than December 31 of the calendar year in which the Issuance Date occurs (that is, the last day of your taxable year in which the Issuance Date occurs), or, if permitted in a manner that complies with Treasury Regulation Section 1.409A-1(b)(4), in no event later than the date that is the 15th day of the third calendar month of the year following the year in which the shares of Common Stock under this Agreement are no longer subject to a “substantial risk of forfeiture” within the meaning of Treasury Regulation Section 1.409A-1(d).

4.PAYMENT BY YOU. Subject to Section 10 below, except as otherwise provided herein or under applicable law, you will not be required to make any payment to the Company with respect to your receipt of the Award, vesting of the Restricted Stock Units, or the delivery of the shares of Common Stock underlying the Restricted Stock Units.

5.SECURITIES LAW COMPLIANCE. You may not be issued any Common Stock under your Award unless the shares of Common Stock are either (i) then registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), or (ii) the Company has determined that such issuance would be exempt from the registration requirements of the Securities Act. Your Award must also comply with other applicable laws and regulations governing the Award, and you shall not receive such Common Stock if the Company determines that such receipt would not be in material compliance with such laws and regulations.

6.RESTRICTIVE LEGENDS. The Common Stock issued under your Award shall be endorsed with appropriate legends, if any, determined by the Company.

7.TRANSFER RESTRICTIONS. Prior to the time that shares of Common Stock have been delivered to you, you may not transfer, pledge, sell or otherwise dispose of the shares in respect of your Award. For example, you may not use shares that may be issued in respect of your Restricted Stock Units as security for a loan, nor may you transfer, pledge, sell or otherwise dispose of such shares. This restriction on transfer will lapse upon delivery to you of shares in respect of

4

your vested Restricted Stock Units. Your Award is not transferable, except by will or by the laws of descent and distribution. In the event of divorce, you are encouraged to discuss the proposed treatment of the Restricted Stock Units with the Company prior to finalizing any domestic relations order if you reside in the United States.

8.AWARD NOT A SERVICE CONTRACT. Your Award is not an employment or service contract, and nothing in your Award shall be deemed to create in any way whatsoever any obligation on your part to continue in the service of the Company or any Affiliate, or on the part of the Company or any Affiliate to continue such service. In addition, nothing in your Award shall obligate the Company or any Affiliate, their respective stockholders, boards of directors or employees to continue any relationship that you might have as an Employee or Consultant of the Company or any Affiliate. Finally, your participation in the Plan shall not create a right to further employment or service with the Employer (as defined in Section 10 below) and shall not interfere with the ability of the Employer to terminate your employment or service relationship at any time with or without cause.

9.UNSECURED OBLIGATION. Your Award is unfunded, and even as to any Restricted Stock Units which vest, you shall be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue Common Stock pursuant to this Agreement. You shall not have voting or any other rights as a stockholder of the Company with respect to the Common Stock acquired pursuant to this Agreement until such Common Stock is issued to you pursuant to Section 3 of this Agreement. Upon such issuance, you will obtain full voting and other rights as a stockholder of the Company with respect to the Common Stock so issuedand held by you. Nothing contained in this Agreement, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person.

10.WITHHOLDING OBLIGATIONS.

(a)You acknowledge that, regardless of any action the Company, or your employer, if different from the Company (whether current or former, the “Employer”) takes with respect to Tax-Related Items, the ultimate liability for any or all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related withholding related to your participation in the Plan and legally applicable to you (“Tax-Related Items”) is and remains your responsibility and may exceed the amount actually withheld by the Employer. You further acknowledge that the Employer (1) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Award, including the grant, vesting or settlement of the Award, the subsequent sale of shares delivered pursuant thereto and the receipt of any dividends; and (2) does not commit to structure the terms of the grant or any aspect of the Award to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result. Further, if you are or become subject to tax in more than one jurisdiction between the Date of Grant and the date of any relevant taxable event or tax withholding even, as applicable, you acknowledge that the Employer may be required to withhold, account for, and/or otherwise cause you to tender a payment to the Employer in the amount of the Tax-Related Items arising in each jurisdiction.

5

(b)On or before the time you receive a distribution of Common Stock pursuant to your Award, or at any time thereafter as requested by the Company, you hereby agree to make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, you hereby authorize the Employer or its respective agents, at their discretion, to withhold all applicable Tax-Related Items by one or a combination of the following: (1) withholding in shares of Common Stock issuable to you upon vesting of the Restricted Stock Units, the number of which shall be determined to comply with appropriate tax laws and as would be otherwise necessary or desirable; or (2) withholding from your wages or other cash compensation paid to you by the Employer and/or the Company; or (3) withholding from the proceeds of the sale of shares of Common Stock acquired upon vesting of the Restricted Stock Units, either through a mandatory sale arranged by the Company (on your behalf pursuant to this authorization without further consent) or a voluntary sale (including permitting or requiring you to enter into an immediate sale commitment with a broker-dealer that is a member of the Financial Industry Regulatory Authority). Notwithstanding that the Appendix for your country may specify a particular method by which the Company or the Employer intends to recover the Tax-Related Items from you, the Company reserves the right to recover Tax-Related Items by any of the methods set forth in Section 10 of this Agreement, except that if you are an executive or director within the meaning of Section 16 of the Exchange Act and the regulations thereunder, Tax-Related Items shall be recovered by withholding in shares of Common Stock as described in this Section 10(b)(1) above.

(c)Depending on the withholding method, the Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding rates or other applicable withholding rates, including maximum applicable rates, in which case you will receive a refund of any over-withheld amount in cash and will have no entitlement to the Common Stock equivalent. If the obligation for the Tax-Related Items is satisfied by withholding in shares of Common Stock, then you will be deemed to have been issued the full number of shares of Common Stock subject to the vested Restricted Stock Units, notwithstanding that a number of the shares are held back solely for the purpose of paying Tax-Related Items. You will have no further rights, title or interests in or to the number of shares of Common Stock that are held back solely for the purpose of paying the Tax-Related Items.

(d)You shall pay to the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold as a result of your receipt of the Award and/or the shares issuable pursuant thereto that cannot be satisfied by the means previously described. Unless the tax withholding obligations of the Company and/or the Employer are satisfied, the Company shall have no obligation to deliver to you any Common Stock or the proceeds from any sale of the shares of Common Stock.

(e)Finally, in the event the Company’s obligation to withhold arises prior to the delivery to you of Common Stock or it is determined after the delivery of Common Stock to you that the amount of the Company’s withholding obligation was greater than the amount withheld by the Company, you agree to indemnify and hold the Company harmless from any failure by the Company to withhold the proper amount.

Vesting. The following provision supplements Section 1 of the Agreement:

7

Notwithstanding any discretion or anything to the contrary in the Plan and/or the Agreement, the grant of the Restricted Stock Units does not provide any right for you to receive a cash payment and the vested Restricted Stock Units will be settled in shares only.

Withholding Obligations. The following provision supplements Section 10 of the Agreement:

If you do not pay or the Company or the Employer does not withhold from you the full amount of income tax that you owe within ninety (90) days of the event giving rise to the Tax-Related Items (the “Due Date”) or such other period specified in Section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions) Act 2003, the amount of any uncollected Tax-Related Items will constitute a loan owed by you to the Employer, effective on the Due Date. You agree that the loan will bear interest at the then-current official rate of Her Majesty’s Revenue and Customs (“HMRC”), it will be immediately due and repayable, and the Company or the Employer may recover it at any time thereafter by any of the means referred to in Section 10 of the Agreement. Notwithstanding the foregoing, if you are a director or executive officer of the Company (within the meaning of Section 13(k) of the U.S. Securities and Exchange Act of 1934, as amended), you will not be eligible for such a loan to cover the Tax-Related Items. In the event that you are a director or executive officer and the Tax-Related Items are not collected from or paid by you by the Due Date, the amount of any uncollected Tax-Related Items will constitute a benefit to you on which additional income tax and national insurance contributions may be payable. You will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for reimbursing the Company or the Employer, as applicable, for the value of any employee national insurance contributions due on this additional benefit, which the Company or the Employer may recover at any time thereafter by any of the means in Section 10 of the Agreement.

Joint Election. As a condition of your participation in the Plan, you agree to accept any liability for secondary Class 1 national insurance contributions (the “Employer’s Liability”) which may be payable by the Company and/or the Employer in connection with the Restricted Stock Units and any event giving rise to Tax-Related Items. Without prejudice to the foregoing, you agree to execute a joint election with the Company (the “Joint Election”) prior to vesting of the Restricted Stock Units, the form of such Joint Election being formally approved by HMRC and attached hereto as Exhibit A, and any other consent or elections required to accomplish the transfer of the Employer’s Liability to you. You further agree to execute such other joint elections as may be required between yourself and any successor to the Company and/or the Employer. You further agree that the Company and/or the Employer may collect the Employer’s Liability by any of the means set forth in Section 10 of the Agreement.

If you do not enter into a Joint Election prior to vesting of the Restricted Stock Units, if approval of the Joint Election has been withdrawn by HMRC or if such Joint Election is jointly revoked by you and the Company or the Employer, as applicable, the Company, in its sole discretion and without any liability to the Company or the Employer, may choose not to issue or deliver any shares to you upon vesting of the Restricted Stock Units.

2006 Employee Equity Incentive Plan Notice of Grant of Stock Options and Option Agreement	Synopsys, Inc.ID: 56-1546236690 East Middlefield Road Mountain View, CA 94043
%%FIRST_NAME%-% %%LAST_NAME%-%%%ADDRESS_LINE_1%-% %%ADDRESS_LINE_2%-% %%CITY%-%, %%STATE%-% %%ZIPCODE%-% %%COUNTRY%-%	Option Number: %%OPTION_NUMBER%-% ID: %%EMPLOYEE_IDENTIFIER%-%

Effective %%OPTION_DATE%-%, Synopsys, Inc. (the “Company”) has granted you a Nonstatutory Stock Option (the “Option”) under the 2006 Employee Equity Incentive Plan (the “Plan”) to buy %%TOTAL_SHARES_GRANTED%-% shares of the common stock of the Company (the “Common Stock”) at an exercise price of %%OPTION_PRICE%-% per share. This Option is subject to all of the terms and conditions set forth in this Notice of Grant of Stock Options and Option Agreement (including any special terms and conditions for your country, if any, in the Appendix hereto, the “Agreement”) and the Plan, which is incorporated by reference herein in its entirety. This Option is also subject to the Compensation Recovery Policy applicable to corporate staff, adopted by the Company in December 2008, as amended from time to time (the “Compensation Recovery Policy”) and any required compensation recovery provisions under applicable laws or regulations. Capitalized terms not explicitly defined in this Agreement but defined in the Plan shall have the same definitions as in the Plan.

This Option will vest, and may be exercised, in whole or in part, in accordance with the following vesting schedule, subject to your Continuous Service with the Company or any Affiliate.

Shares	Vest Type	Full Vest	Expiration
%%SHARES_PERIOD1%-%	On Vest Date	%%VEST_DATE_PERIOD1%-%	%%EXPIRE_DATE_PERIOD1%-%
%%SHARES_PERIOD2%-%	Quarterly	%%VEST_DATE_PERIOD2%-%	%%EXPIRE_DATE_PERIOD2%-%

1.Exercise.

(a)Right to Exercise. This Option is exercisable during its term in accordance with the vesting schedule set forth above and the applicable provisions of the Plan and this Agreement. In the event of your death, disability, or other cessation of Continuous Service, the exercisability of the Option is governed by the applicable provisions of the Plan and this Agreement. This Option may not be exercised for a fraction of a Share.

1

(b)Method of Exercise. You must exercise your Option through your account with the Company’s designated broker, which as of the date hereof is E*Trade Securities LLC, unless you are an officer subject to the reporting requirements of Section 16(a) of the U.S. Securities Exchange Act of 1934 (a “Section 16 Officer”). Using your account, you may select the grant to exercise, the number of shares to exercise, the type of exercise (subject to applicable provisions in the Appendix), and, if applicable based on the type of exercise, the sales order for the shares issuable upon exercise. You may sell the Common Stock underlying the Option through your account or you may transfer the shares of Common Stock to your stockbroker (except as provided in the Appendix). If you are a Section 16 Officer, you must exercise your Option in accordance with the Company’s Section 16 Officer and Director Trading Procedures. All Option exercises must be made in accordance with the Company’s Insider Trading Policy.

(c)Exercise by Another. If another person wants to exercise this Option after it has been transferred to him or her in accordance with the transferability restrictions provided in the Plan, that person must prove to the Company’s satisfaction that he or she is entitled to exercise this Option. That person must also pay the exercise price (as described below) and any applicable tax withholding due upon exercise of the Option (as described below).

(d)Method of Payment. Payment of the exercise price is due in full upon exercise of all or any part of the Option. Payment of the exercise price may be made in cash or by check or in any other manner permitted in the Plan (except as provided in the Appendix).

(e)Termination. In the event of termination of your Continuous Service for any reason other than Cause, you will be permitted to exercise the Option to the extent vested at the time of termination for ninety (90) days following your date of termination (except as provided in the Appendix); provided, however, that if your termination is due to death or disability, or if you die within ninety (90) days following your termination without “Cause”, the post-termination exercise period is twelve (12) months (except as provided in the Appendix); provided further that if your termination is for “Cause” as defined in the Plan, you shall not be permitted to exercise the Option in any respect. In each case, the date of the termination of your Continuous Service shall be determined in accordance with Section 3(j) below. In addition, if your Option is not exercisable during the applicable post-termination exercise period solely because the shares of Common Stock issuable upon such exercise are not then registered under the Securities Act and are not otherwise issuable under an exemption from the registration requirements of the Securities Act, this Option shall not expire until the earlier of the expiration date set forth above or until it shall have been exercisable for an aggregate period of at least ninety (90) days after the termination of your Continuous Service. You are responsible for keeping track of these exercise periods following your termination of Continuous Service for any reason. The Company will not provide further notice of such periods.

2.Responsibility for Taxes. Except as otherwise provided in the Appendix, the provisions of this Section 2 shall apply. You acknowledge that, regardless of any action the Company or your employer (if different from the Company) (the Company or your employer referred to hereinafter as the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related withholding related to your

2

participation in the Plan and legally applicable to you (“Tax-Related Items”), the ultimate liability for all Tax-Related Items is and remains your responsibility and may exceed the amount actually withheld by the Employer. You further acknowledge that the Employer (1) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option, including the grant, vesting or exercise of the Option, the subsequent sale of shares acquired pursuant to such exercise and the receipt of any dividends; and (2) does not commit to structure the terms of the grant or any aspect of the Option to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result. In particular, you acknowledge that this Option is exempt from Section 409A of the U.S. Internal Revenue Code only if the exercise price per share is at least equal to the “fair market value” per share of the Common Stock on the grant date and there is no other impermissible deferral of compensation associated with the Option. Further, if you have become subject to tax in more than one jurisdiction between the date of grant and the date of any relevant taxable event or tax withholding event, as applicable, you acknowledge that the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to exercise of the Option, you shall pay or make adequate arrangements satisfactory to the Employer to satisfy all Tax-Related Items. In this regard, you authorize the Employer or its respective agents, at their discretion, to withhold all applicable Tax-Related Items from your wages or other cash compensation paid to you by the Employer and/or from proceeds of the sale of the shares. Alternatively, or in addition, if permissible under local law, the Employer may, without your further consent, (1) sell or arrange for the sale of shares that you acquire, to meet the withholding obligation for Tax-Related Items, either through a mandatory sale arranged by the Company (on your behalf pursuant to this authorization) or a voluntary sale (including permitting you to enter into a “same day sale” commitment with a broker-dealer that is a member of the Financial Industry Regulatory Authority), and/or (2) withhold in shares of Common Stock issuable at exercise of the Option. Depending on the withholding method, the Employer may withhold or account for Tax-Related Items by considering applicable minimum withholding rates or other applicable withholding rates, including maximum applicable rates, in which case you will receive a refund of any over-withheld amount in cash and will have no entitlement to the share equivalent. If the obligation for the Tax-Related Items is satisfied by withholding in shares of Common Stock, then you will have no further rights, title or interests in or to the number of shares of Common Stock that are held back solely for the purpose of paying the Tax-Related Items, and you are deemed to have been issued the full number of shares of Common Stock subject to the vested exercised Option.

Finally, you shall pay to the Employer any amount of Tax-Related Items that the Employer may be required to withhold as a result of your receipt or exercise of the Option and your sale of the shares obtained pursuant to any exercise of the Option that cannot be satisfied by the means previously described. The Employer may refuse to honor the exercise and refuse to deliver the shares if you fail to comply with your obligations in connection with the Tax-Related Items as described in this section.

3.Nature of Grant. In accepting the grant of the Option, you acknowledge, understand and agree that:

(a)the Plan is established voluntarily by the Company, is discretionary in nature, and may be modified, amended, suspended or terminated by the Company as provided in the Plan;

(b)the grant of the Option and any other options or Awards under the Plan is voluntary and occasional and does not create any contractual or other right to receive future grants of options, shares, Awards or any other benefit or compensation in lieu of future options, even if options have been granted in the past;

(c)all decisions with respect to future Awards, if any, will be at the sole discretion of the Company;

(d)your participation in the Plan shall not create a right to employment or service or be interpreted as forming an employment or service contract with the Company, your employer (if different than the Company) or any Affiliate and shall not interfere with the ability of the Company, the employer or any Affiliate to terminate your employment or service relationship at any time with or without cause;

(e)you are voluntarily participating in the Plan;

(f)unless otherwise agreed with the Company, the Option and any shares of Common Stock subject to the Option, and the income and value of same, are not granted as consideration for, or in connection with, the service you may provide as a director of an Affiliate of the Company;

(g)the Option is an extraordinary item that does not constitute compensation of any kind for services of any kind rendered to the Employer, and that is outside the scope of your employment or service contract, if any;

(h)the Option and the shares of Common Stock subject to the Option are not intended to replace any pension rights or compensation;

(i)the Option and any income derived therefrom is not paid in lieu of any normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, life or accident insurance benefits, pension or retirement benefits or similar payments;

(j)for purposes of the Option, your Continuous Service will be considered terminated as of the date determined by the Company in its sole discretion;

(k)the future value of the shares underlying the Option is unknown and cannot be predicted with certainty;

(l)if the value of the underlying shares does not exceed the exercise price upon exercise, the Option will have no value and if you exercise the Option, the value of the shares acquired upon exercise may increase or decrease in value, even below the exercise price;

4

(m)you understand that should you die owning shares of Common Stock or the Option, such shares or the Option may subject your estate to United States federal estate taxes. You understand that you should seek your own tax advice regarding this potential tax;

(n)you disclaim any entitlement to compensation or damages arising from the termination of the Option, including as the result of termination of your employment or other service relationship with the Employer (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where you are employed or providing services or the terms of any employment or service agreement), or diminution in value of the shares of Common Stock, and in consideration of the grant of the Option to which you are not otherwise entitled, you hereby agree not to bring any claim against the Company, the Employer and any Affiliate, irrevocably waive your ability, if any to bring such claim, and release the Company, the Employer and any Affiliate from any such claim that may arise;

(o)the Plan and the Agreement set forth the entire understanding between you, the Company, the Employer, and any Affiliate thereof regarding the acquisition of the shares of Common Stock and supersedes all prior oral and written agreements pertaining to the Option; and

(p)the following provisions apply only if you are providing services outside the United States:

(i)    the Option and the shares of Common Stock subject to the Option, and the value and income of same, are not part of normal or expected compensation or salary for any purpose; and

(ii)    neither the Company, the Employer nor any Affiliate shall be liable for any foreign exchange rate fluctuation between your local currency and the United States Dollar that may affect the value of the Option or of any amounts due to you pursuant to the exercise of the Option or the subsequent sale of any shares of Common Stock acquired upon exercise.

4.Data Privacy. You hereby explicitly, voluntarily and unambiguously consent to the collection, use and transfer, in electronic or other form, of your personal data as described in this Agreement by and among, as applicable, the Company, the Employer and any Affiliate for the exclusive purpose of implementing, administering and managing your participation in the Plan.

You authorize the recipients to receive, possess, use, retain and transfer the Personal Data, in electronic or other form, for the purposes of implementing, administering and managing your participation in the Plan, including any requisite transfer of such Personal Data as may be required to a broker or other third party with whom you may elect to deposit any shares of stock acquired upon exercise of the Option. You understand that Personal Data will be held only as long as is necessary to implement, administer and manage your participation in the Plan.

Responsibility for Taxes. The following provision supplements Section 2 of the Agreement:

If you do not pay or the Company or the Employer does not withhold from you the full amount of any income tax that you owe within ninety (90) days of the event giving rise to the Tax-Related Items (the “Due Date”) or such other period specified in Section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions) Act 2003, the amount of any uncollected income tax will constitute a loan owed by you to the Employer, effective on the Due Date. You agree that the loan will bear interest at the then-current official rate of Her Majesty’s Revenue and Customs (“HMRC”), it will be immediately due and repayable, and the Company or the Employer may recover it at any time thereafter by any of the means referred to in Section 2 of the Agreement. Notwithstanding the foregoing, if you are a director or executive officer of the Company (within the meaning of Section 13(k) of the U.S. Securities and Exchange Act of 1934, as amended), you will not be eligible for such a loan to cover the income tax. In the event that you are a director or executive officer and the income tax is not collected from or paid by you by the Due Date, the amount of any uncollected income tax will constitute a benefit to you on which additional income tax and national insurance contributions (including the Employer’s Liability, as defined below) may be payable. You will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for reimbursing the Company or the Employer, as applicable, for the value of any employee national insurance contributions due on this additional benefit, which

6

the Company or the Employer may recover at any time thereafter by any of the means in Section 2 of the Agreement.

As a condition of participation in the Plan, you agree to accept any liability for secondary Class 1 national insurance contributions (the “Employer’s Liability”) which may be payable by the Company and/or the Employer in connection with the Option and any event giving rise to Tax-Related Items. Without prejudice to the foregoing, you agree to execute a joint election with the Company (the “Joint Election”) prior to exercising the Option, the form of such Joint Election being formally approved by HMRC and attached hereto as Exhibit A, and any other consent or elections required to accomplish the transfer of the Employer’s Liability to you. You further agree to execute such other joint elections as may be required between yourself and any successor to the Company and/or the Employer. You further agree that the Company and/or the Employer may collect the Employer’s Liability by any of the means set forth in Section 2 of the Agreement.

If you do not enter into a Joint Election prior to exercising the Option, if approval of the Joint Election has been withdrawn by HMRC or if such Joint Election is jointly revoked by you and the Company or the Employer, as applicable, this Option shall, at the discretion of the Company, without any liability to the Company or the Employer, not be exercisable and/or the Company may choose not to issue or deliver any shares upon exercise of the Option.

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 (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 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, 2014 as filed with the SEC on December 15, 2014.

Use of Estimates. To prepare financial statements in conformity with 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.

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 2015 and 2014 are both 52-week years. The second fiscal quarters, and first six months, of fiscal 2015 and 2014 ended on May 2, 2015 and May 3, 2014, respectively, and the prior fiscal year ended on November 1, 2014. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.

Subsequent Events. The Company has evaluated subsequent events through the date that these unaudited condensed consolidated financial statements were issued.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Effect of New Accounting Pronouncements

Effect of New Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, "Revenue from Contracts with Customers (Topic 606)," which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605).” This ASU requires an entity to recognize revenue when goods are transferred or services are provided to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. This ASU also requires disclosures enabling users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance will be effective for fiscal 2018 unless an extension of the effective date is granted by the FASB, including interim periods within that reporting period, using one of two prescribed retrospective methods. The Company is currently in the process of evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method, nor has it determined the effect of the standard on its ongoing financial reporting.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Apr. 30, 2015

Accounting Policies [Abstract]

Use of Estimates

Use of Estimates. To prepare financial statements in conformity with 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.

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 2015 and 2014 are both 52-week years. The second fiscal quarters, and first six months, of fiscal 2015 and 2014 ended on May 2, 2015 and May 3, 2014, respectively, and the prior fiscal year ended on November 1, 2014. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.

Subsequent Events

Subsequent Events. The Company has evaluated subsequent events through the date that these unaudited condensed consolidated financial statements were issued.

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 stockholders 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:

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, short-term investments, non-qualified deferred compensation plan assets, and foreign currency derivative contracts.

The Company’s cash equivalents and short-term investments are classified within Level 1 or Level 2 because they are valued using quoted market prices in an active market or alternative independent pricing sources and models utilizing market observable inputs.

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. Refer to Note 7. Credit Facility.

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 cost 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 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. 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 and six months ended April 30, 2015 and 2014, respectively.

As of April 30, 2015, the fair value of the Company’s non-marketable securities was $10.9 million, of which $6.7 million and $4.2 million were accounted for under the cost method and equity method, respectively. As of October 31, 2014, the fair value of non-marketable securities was $10.9 million, of which $6.7 million and $4.2 million were accounted for under the cost method and equity method, respectively.

Financial Assets And Liabilities [Abstract]

Financial Assets and Liabilities

Financial Assets and Liabilities

Cash equivalents and short-term investments. The Company classifies time deposits and other investments with maturities less than three months as cash equivalents. Debt securities and other investments with maturities longer than three months are classified as short-term investments. The Company’s investments generally have a term of less than three years and are classified as available-for-sale carried at fair value, with unrealized gains and losses included in the unaudited condensed consolidated balance sheet as a component of accumulated other comprehensive income (loss), net of tax. Those unrealized gains or losses deemed other than temporary are reflected in other income (expense), net. The cost of securities sold is based on the specific identification method and realized gains and losses are included in other income (expense), net.

During the first fiscal quarter of 2015, the Company made investments in available-for-sale securities. As of April 30, 2015, the balances of these investments are:

As of April 30, 2015, the stated maturities of the Company's short-term investments are:

	Amortized Cost		Fair Value
	(in thousands)

Due in 1-5 years	61,737		61,761
Total	$	136,549	$	136,579

Non-marketable equity securities. The Company’s strategic investment portfolio consists of non-marketable equity securities in privately-held companies. The securities accounted for under cost method investments are reported at cost net of impairment losses. Securities accounted for under 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. Refer to Note 5. Fair Value Measures.

Derivatives. The Company recognizes derivative instruments as either assets or liabilities in the unaudited condensed consolidated financial statements 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. Further, the Company 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.

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 effective portion of 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 (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 twelve months.

Hedging effectiveness is evaluated monthly using spot rates, with any gain or loss caused by hedging ineffectiveness recorded in other income (expense), net. The premium/discount component of the forward contracts is recorded to other income (expense), net, and is not included in evaluating hedging effectiveness.

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.

The effects of the changes in the fair values of non-designated forward contracts are summarized as follows:

	Three Months Ended   April 30,					Six Months Ended   April 30,
	2015			2014		2015			2014
	(in thousands)
Gain (loss) recorded in other income (expense), net	$	(235	)	$	330	$	(2,993	)	$	(613	)

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

	(in thousands)
Total gross notional amount	$	702,008		$	793,937
Net fair value	$	(5,436	)	$	(2,455	)

The notional amounts for derivative instruments do not represent the amount of the Company’s exposure to market gain or loss. 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 represents the unaudited condensed consolidated balance sheet location and amount of derivative instrument fair values segregated between designated and non-designated hedge instruments:

The Restated Credit Agreement amends and restates the Company’s previous Credit Agreement referred to in Note 7, in order to increase the size of the revolving credit facility from $350.0 million to $500.0 million and to extend the termination date of the revolving credit facility from October 14, 2016 to May 19, 2020. The Restated Credit Agreement also replaces a financial covenant requiring the Company to maintain a minimum specified level of cash with a covenant requiring a minimum interest coverage ratio. Otherwise, the terms and conditions of the Restated Credit Agreement are substantially similar to the previous Credit Agreement. The Company's outstanding Revolver and Term Loan borrowings under the previous Credit Agreement, described in Note 7, are carried over under the Restated Credit Agreement. The Company expects its borrowings under the Restated Credit Agreement will fluctuate from quarter to quarter.

Segment Reporting [Abstract]

Segment Disclosure

Segment Disclosure

Certain disclosures are required for operating segments, products and services, geographic areas of operation and major customers. 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 the Company’s two Co-Chief Executive Officers.

The Company operates in a single segment to provide software products and consulting services in the EDA software industry. In making operating decisions, the CODMs primarily consider consolidated financial information, accompanied by disaggregated information about revenues by geographic region. Specifically, the CODMs consider where individual “seats” or licenses to the Company’s products are located in allocating revenue to particular geographic areas. Revenue is defined as revenues from external customers. Goodwill is not allocated since the Company operates in one reportable operating segment. Revenues related to operations in the United States and other geographic areas were:

Credit Facility

Credit Facility

On February 17, 2012, the Company entered into an agreement with several lenders (the Credit Agreement) providing for (i) a $350.0 million senior unsecured revolving credit facility (the Revolver) and (ii) a $150.0 million senior unsecured term loan facility (the Term Loan). Principal payments on a portion of the Term Loan are due in equal quarterly installments of $7.5 million, with the remainder due when the Credit Agreement expires in October 2016. The Company can elect to make prepayments on the Term Loan, in whole or in part, without premium or penalty. 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 through October 13, 2015. The Credit Agreement contains financial covenants requiring the Company to operate within a maximum leverage ratio and maintain specified levels of cash, as well as other non-financial covenants.

In December 2014, the Company drew down $250.0 million under the Revolver, primarily to finance an accelerated share repurchase agreement. See Note 9. Stock Repurchase Program. During the six monthsended April 30, 2015, the Company made a principal payment of $15.0 million under the Term Loan and $90.0 million under the Revolver. As of April 30, 2015, the Company had a $60.0 million outstanding balance under the Term Loan, of which $30.0 million is classified as long term, and a $160.0 million outstanding balance under the Revolver, which is all considered short term. As of October 31, 2014, the Company had a $75.0 million outstanding balance under the Term Loan, of which $45.0 million was classified as long term, and no outstanding balance under the Revolver. 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, 2015, borrowings under the Term Loan bore interest at LIBOR +1.125% and the applicable interest rate for the Revolver was LIBOR +0.975%. In addition, commitment fees are payable on the Revolver at rates between 0.150% and 0.300% per year based on the Company’s leverage ratio on the daily amount of the revolving commitment.

The Credit Agreement was amended and restated on May 19, 2015. See Note 16. Subsequent Events for details.

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.

Stock Repurchase Program [Abstract]

Stock Repurchase Program

Stock Repurchase Program

The Company’s Board of Directors (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 December 3, 2013, as announced on December 4, 2013. The program does not obligate Synopsys to acquire any particular amount of common stock, and the program may be suspended or terminated at any time by Synopsys’ 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, 2015, $200.3 million remained available for further repurchases under the program.

In December 2014, the Company entered into an accelerated share repurchase agreement (2015 ASR) to repurchase an aggregate of $180.0 million of the Company’s common stock. Pursuant to the 2015 ASR, the Company made a prepayment of $180.0 million and received an initial share delivery of shares valued at $144.0 million with an average purchase price of $43.77 per share. The remaining balance of $36.0 million will be settled within 6 months or earlier upon completion of the repurchase and is included within stockholders' equity as the forward instrument meets the criteria in the Financial Accounting Standards Board (FASB) authoritative guidance for equity treatment. Under the terms of the 2015 ASR, the specific number of shares that the Company ultimately repurchases will be based on the volume-weighted average share price of the Company’s common stock during the repurchase period, less a discount.

Stock repurchase activities are as follow:

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

Effective Tax Rate

The Company estimates its annual effective tax rate at the end of each fiscal quarter. The Company’s estimate takes into account estimations of annual pre-tax income, the geographic mix of pre-tax income and the Company’s interpretations of tax laws and possible outcomes of audits.

The following table presents the provision for income taxes and the effective tax rates:

	Three Months Ended   April 30,						Six Months Ended   April 30,
	2015			2014			2015			2014
	(in thousands)
Income before income taxes	$	83,884		$	68,059		$	160,499		$	139,243
Provision (benefit) for income tax	$	28,288		$	4,742		$	39,714		$	8,230
Effective tax rate	33.7		%	7.0		%	24.7		%	5.9		%

The Company’s effective tax rate for the three and six months ended April 30, 2015 is lower than the statutory federal income tax rate of 35% primarily due to the lower tax rates applicable to its non-U.S. operations and U.S. federal and California research tax credits, partially offset by state taxes, non-deductible stock compensation, and the integration of acquired technologies.

The Company's effective tax rate increased in the three and six months ended April 30, 2015, as compared to the same periods in fiscal 2014, primarily due to the integration of acquired technologies, partially offset by the reinstatement of the U.S. federal research tax credit in the first quarter of fiscal 2015. The effective tax rate for the three and six months ended April 30, 2014 was lower due to the tax benefits of settlements with the Taiwan tax authorities for fiscal 2010 and 2009 and with the IRS for fiscal 2012.

On December 19, 2014, the president signed into law the Tax Increase Prevention Act of 2014 which reinstated the research tax credit retroactive to January 1, 2014 and extended the credit through December 31, 2014. As a result of the new legislation, the Company recognized a benefit in the first quarter of fiscal 2015 related to ten months of fiscal 2014 as well as a benefit to the annual effective tax rate for two months of fiscal 2015. During fiscal 2015 the Company estimates the benefit of the reinstatement of the research tax credit to be approximately $12.4 million.

The Company’s total gross unrecognized tax benefits at April 30, 2015 are $129.9 million exclusive of interest and penalties. If the total gross unrecognized tax benefits at April 30, 2015 were recognized in the future, approximately $129.9 million would decrease the effective tax rate.

The timing of the resolution of income tax examinations is highly uncertain as well as the amounts and timing of various tax payments that are part of the settlement process. This could cause large fluctuations in the balance sheet classification of current and non-current assets and liabilities. The Company believes that in the coming twelve months, it is reasonably possible that either certain audits 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 $37 million.

IRS Examinations

In the first quarter of fiscal 2014, the Company reached final settlement with the Examination Division of the IRS on the remaining fiscal 2012 issues and recognized approximately $10.0 million in unrecognized tax benefits.

Non-U.S. Examinations

In the first quarter of fiscal 2015, the Company reached final settlement with the Taiwan tax authorities for fiscal 2012, with regard to certain transfer pricing issues. As a result of the settlement the Company recognized approximately $1.1 million in unrecognized tax benefits.

In the second quarter of fiscal 2014, the Company reached settlements with the Taiwan tax authorities for fiscal 2010 and 2009, with regard to certain transfer pricing issues. As a result of the settlements and the application of the settlements to other open fiscal years, the Company's unrecognized tax benefits decreased by $5.1 million. The net tax benefit resulting from the settlements and the application to other open fiscal years was $3.9 million.
