Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The Company has prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Pursuant to these rules and regulations, the Company has condensed or omitted certain information and footnote disclosures it normally includes in its annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (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, 2015 as filed with the SEC on December 14, 2015. 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 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. Fiscal 2016 and 2015 are both 52-week years. The second fiscal quarters of fiscal 2016 and 2015 ended on April 30, 2016 and May 2, 2015, respectively, and the prior fiscal year ended on October 31, 2015. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.

Business Combinations [Abstract]
Business Combinations	Business Combinations During the six months ended April 30, 2016, the Company completed several acquisitions. The aggregate total purchase consideration was $40.4 million , net of cash acquired. The Company does not consider these acquisitions to be material, individually or in the aggregate, to the Company’s consolidated balance sheet and results of operations. The preliminary purchase price allocations resulted in $27.2 million of goodwill, of which $6.1 million is deductible for tax purposes, and $16.9 million of acquired identifiable intangible assets valued using an income method. The intangible assets are being amortized over their respective useful lives ranging from one to seven years. The acquisition-related costs for these acquisitions totaling $2.0 million were expensed as incurred in the condensed unaudited consolidated statement of operations. The Company funded the acquisitions with existing cash. The preliminary fair value estimates for the assets acquired and liabilities assumed for all fiscal 2016 acquisitions are not yet finalized and may change as additional information becomes available during the respective measurement periods. The primary areas of those preliminary estimates relate to certain tangible assets and liabilities, identifiable intangible assets, and taxes. Additional information, which existed as of the acquisition date but is not yet known to the Company, may become known to the Company during the remainder of the measurement period, a period not to exceed 12 months from the acquisition date. Changes to the provisional amounts recorded as assets or liabilities during the measurement period may result in an adjustment to goodwill.

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 sheets 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.

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 6. 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 12 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 Six Months Ended 2016 2015 2016 2015 (in thousands) Gain (loss) recorded in other income (expense), net $ 1,914 $ (235 ) $ (1,849 ) $ (2,993 ) The notional amounts in the table below for derivative instruments provide one measure of the transaction volume outstanding: As of April 30, 2016 As of October 31, 2015 (in thousands) Total gross notional amount $ 719,816 $ 781,752 Net fair value $ (9,203 ) $ (3,819 ) 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.

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 8. Credit Facility . Assets and Liabilities Measured at Fair Value on a Recurring Basis Assets and liabilities measured at fair value on a recurring basis are summarized below as of April 30, 2016 : Fair Value Measurement Using Description Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in thousands) Assets Cash equivalents: Money market funds $ 308,004 $ 308,004 $ — $ — Commercial paper 600 — 600 — Certificates of deposit 4,901 — 4,901 — U.S. government agency securities 3,399 — 3,399 — Short-term investments: U.S. government agency securities 11,612 — 11,612 — Municipal bonds 1,402 — 1,402 — Certificates of deposit 13,598 — 13,598 — Commercial paper 12,010 — 12,010 — Corporate debt securities 66,811 — 66,811 — Asset-backed securities 20,589 — 20,589 — Non-U.S. government agency securities 1,004 — 1,004 — Other 4,950 4,950 — — Prepaid and other current assets: Foreign currency derivative contracts 5,284 — 5,284 — Other long-term assets: Deferred compensation plan assets 157,135 157,135 — — Total assets $ 611,299 $ 470,089 $ 141,210 $ — Liabilities Accounts payable and accrued liabilities: Foreign currency derivative contracts $ 14,487 $ — $ 14,487 $ — Other long-term assets: Deferred compensation plan liabilities 157,135 157,135 — — Total liabilities $ 171,622 $ 157,135 $ 14,487 $ — Assets and liabilities measured at fair value on a recurring basis are summarized below as of October 31, 2015 : Fair Value Measurement Using Description Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in thousands) Assets Cash equivalents: Money market funds $ 233,839 $ 233,839 $ — $ — Commercial paper 1,834 — 1,834 — Certificates of deposit 3,500 — 3,500 — Asset-backed securities 299 — 299 — Short-term investments: U.S. government agency securities 12,614 — 12,614 — Municipal bonds 1,403 — 1,403 — Certificates of deposit 9,800 — 9,800 — Commercial paper 12,129 — 12,129 — Corporate debt securities 67,188 — 67,188 — Asset-backed securities 24,608 — 24,608 — Non-U.S. government agency securities 1,005 — 1,005 — Prepaid and other current assets: Foreign currency derivative contracts 6,462 — 6,462 — Other long-term assets: Deferred compensation plan assets 158,462 158,462 — — Total assets $ 533,143 $ 392,301 $ 140,842 $ — Liabilities Accounts payable and accrued liabilities: Foreign currency derivative contracts $ 10,281 $ — $ 10,281 $ — Other long-term liabilities: Deferred compensation plan liabilities 158,462 158,462 — — Total liabilities $ 168,743 $ 158,462 $ 10,281 $ — 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 six months ended April 30, 2016 and 2015 , respectively. As of April 30, 2016 , the fair value of the Company’s non-marketable securities was $8.7 million , of which $6.2 million and $2.5 million were accounted for under the cost method and equity method, respectively. As of October 31, 2015 , the fair value of non-marketable securities was $10.3 million , of which $6.6 million and $3.7 million were accounted for under the cost method and equity method, respectively.

Credit Facility	Apr. 30, 2016
Debt Disclosure [Abstract]
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 in October 2016. The Company can elect to make prepayments on the Term Loan, in whole or in part, without premium or penalty. On May 19, 2015, the Credit Agreement was amended and restated in order to increase the size of the Revolver from $350.0 million to $500.0 million and to extend the termination date of the Revolver from October 14, 2016 to May 19, 2020 . The amended and restated Credit Agreement also replaced a financial covenant requiring the Company to maintain a minimum specified level of cash with a covenant requiring a minimum interest coverage ratio. Subject to obtaining additional commitments from lenders, the principal amount of the loans provided under the amended and restated Credit Agreement may be increased by the Company by up to an additional $150.0 million through May 2019. The amended and restated Credit Agreement contains financial covenants requiring the Company to operate within a maximum leverage ratio and a minimum interest coverage ratio, as well as other non-financial covenants. As of April 30, 2016 , the Company is in compliance with all financial covenants. As of April 30, 2016 , the Company had a $30.0 million outstanding balance under the Term Loan and a $220.0 million outstanding balance under the Revolver, all of which are considered short-term liabilities. As of October 31, 2015 , the Company had a $45.0 million outstanding balance under the Term Loan and a $160.0 million outstanding balance under the Revolver, all of which are considered short-term liabilities. 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 amended and restated Credit Agreement. As of April 30, 2016 , borrowings under the Term Loan bore interest at LIBOR +1.125% and the applicable interest rate for the Revolver was LIBOR +1.000% . In addition, commitment fees are payable on the Revolver at rates between 0.125% and 0.200% per year based on the Company’s leverage ratio on the daily amount of the revolving commitment. Subsequent to the end of the quarter, the Company drew down an additional $125.0 million under the Revolver. The total outstanding balance of the Revolver as of May 24, 2016 is $335.0 million , net of repayments. The carrying amount of the short-term and long-term debt approximates the estimated fair value. These borrowings under the amended and restated 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 (the Board) previously approved a stock repurchase program pursuant to which the Company was authorized to purchase up to $500.0 million of its common stock, and has periodically replenished the stock repurchase program to such amount. The Board replenished the stock repurchase program up to $500.0 million on September 1, 2015. 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, 2016 , $300.0 million remained available for further repurchases under the program. In August 2015, the Company entered into an accelerated share repurchase agreement (the August 2015 ASR) to repurchase an aggregate of $100.0 million of the Company’s common stock. Pursuant to the August 2015 ASR, the Company made a prepayment of $100.0 million and received an initial share delivery of shares valued at $80.0 million . The remaining balance of $20.0 million was settled in the first quarter of fiscal 2016. Total shares purchased under the August 2015 ASR were approximately 2.1 million shares, at an average purchase price of $48.06 per share. In December 2015, the Company entered into two simultaneous accelerated share repurchase agreements (the December 2015 ASRs) to repurchase an aggregate of $200.0 million of the Company’s common stock. Pursuant to the December 2015 ASRs, the Company made a prepayment of $200.0 million and received initial share deliveries of shares valued at $160.0 million . The December 2015 ASRs expired on April 29, 2016 with $20.0 million settled in April 2016 and the final $20.0 million settled in May 2016. Total shares purchased under the December 2015 ASRs were approximately 4.5 million shares, at an average purchase price of $44.40 per share. In May 2016, the Company entered into an accelerated share repurchase agreement (the May 2016 ASR) to repurchase an aggregate of $125.0 million of the Company’s common stock. Pursuant to the May 2016 ASR, the Company will make a prepayment of $125.0 million to receive initial share deliveries of shares valued at $100.0 million . The remaining balance of $25.0 million is anticipated to be settled on or before August 15, 2016, upon completion of the repurchase. Under the terms of the May 2016 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 Six Months Ended 2016 2015 2016 2015 (in thousands) Total shares repurchased (1) 515 — 4,364 3,290 Total cost of the repurchased shares(1) $ 20,000 $ — $ 200,000 $ 144,000 Reissuance of treasury stock 1,261 1,597 1,462 2,379 (1) Does not include the final 517,410 shares and $20.0 million equity forward contract, respectively, from the December 2015 ASRs settled in May 2016.

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.

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: Three Months Ended Six Months Ended 2016 2015 2016 2015 (in thousands) Revenue: United States $ 297,388 $ 286,113 $ 572,318 $ 563,700 Europe 73,112 75,025 145,047 146,908 Japan 58,535 53,242 111,781 114,094 Asia-Pacific and Other 175,970 142,824 344,463 274,545 Consolidated $ 605,005 $ 557,204 $ 1,173,609 $ 1,099,247 Geographic revenue data for multi-region, multi-product transactions reflect internal allocations and are therefore subject to certain assumptions and the Company’s methodology. The aggregate revenue derived from one customer and its subsidiaries through multiple agreements accounted for 14.5% and 12.3% of the Company’s unaudited condensed consolidated revenue in the three months ended April 30, 2016 and 2015 , respectively, and accounted for 13.8% and 11.8% of the Company’s unaudited condensed consolidated revenue in the six months ended April 30, 2016 and 2015 , respectively.

Income Tax Disclosure [Abstract]
Taxes	Taxes Effective Tax Rate The Company estimates its annual effective tax rate at the end of each fiscal quarter. The effective tax rate takes into account the Company's estimations of annual pre-tax income, the geographic mix of pre-tax income and interpretations of tax laws and possible outcomes of audits. The following table presents the provision (benefit) for income taxes and the effective tax rates: Three Months Ended Six Months Ended 2016 2015 2016 2015 (in thousands) Income before income taxes $ 97,223 $ 83,884 $ 161,565 $ 160,499 Provision (benefit) for income taxes $ 27,847 $ 28,288 $ 32,154 $ 39,714 Effective tax rate 28.6 % 33.7 % 19.9 % 24.7 % The Company’s effective tax rate for the three and six months ended April 30, 2016 is lower than the statutory federal income tax rate of 35% primarily due to lower taxes on certain earnings considered as indefinitely reinvested in foreign operations and U.S. federal and California research tax credits, partially offset by state taxes and the tax effect of non-deductible stock compensation and the integration of acquired technologies. The integration of acquired technologies represents the income tax effect resulting from the transfer of certain intangible assets among company-controlled entities. The Company's effective tax rate decreased in the three and six months ended April 30, 2016 , as compared to the same periods in fiscal 2015 , primarily due to the permanent reinstatement of the U.S. federal research tax credit and an amendment to its intercompany cost-sharing arrangements to exclude stock-based compensation expense, partially offset by an increase in the valuation allowance on deferred tax assets. On December 18, 2015, the president signed into law the Protecting Americans from Tax Hikes Act of 2015 which permanently reinstated the research tax credit retroactive to January 1, 2015. As a result of the new legislation, the Company recognized a benefit in the first quarter of 2016 related to ten months of fiscal 2015 and two months of fiscal 2016 as well as a benefit to the annual effective tax rate for ten months of fiscal 2016. 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. On July 27, 2015, the Tax Court issued an opinion ( Altera Corp. et al. v. Commissioner ) regarding the treatment of stock-based compensation expense in intercompany cost-sharing arrangements. The U.S. Treasury has not withdrawn the requirement to include stock-based compensation from its regulations and the IRS has initiated an appeal of the Tax Court's opinion. As the final resolution with respect to historical cost-sharing of stock-based compensation, and the potential favorable benefits to the Company, is unclear, the Company is recording no impact at this time and will continue to monitor developments related to this opinion and the potential impact of those developments on the Company's prior fiscal years. Effective February 1, 2016, the Company amended its cost-sharing arrangement to exclude stock-based compensation expense on a prospective basis and has reflected the corresponding benefits in its effective annual tax rate. The Company’s total gross unrecognized tax benefits as of April 30, 2016 are $112.1 million exclusive of interest and penalties. If the total gross unrecognized tax benefits as of April 30, 2016 were recognized in the future, approximately $109.2 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 12 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 $20 million . During the first quarter of fiscal 2016, the Company early adopted Accounting Standards Update (ASU) 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (ASU 2015-17) on a retrospective basis. As required by ASU 2015-17, all deferred tax assets and liabilities are classified as non-current in the Company's unaudited condensed consolidated balance sheets, which is a change from the Company's prior period presentations whereby certain of its deferred tax assets were classified as current and the remainder were classified as non-current. Upon adoption of ASU 2015-17, current deferred tax assets of $95.0 million in the Company's October 31, 2015 consolidated balance sheet were reclassified as non-current. State Examinations In the first quarter of fiscal 2016, the Company reached final settlement with the California Franchise Tax Board for fiscal 2011, 2010 and 2009. As a result of the settlement, the Company reduced its deferred tax assets by $4.9 million , recognized $10.3 million in unrecognized tax benefits, and increased its valuation allowance by $5.4 million . Non-U.S. Examinations In the second quarter of fiscal 2016, the Company agreed to settle certain transfer pricing issues with the Indian tax authorities for fiscal years 2010 to 2015. As a result of the settlement, the Company recognized income tax expense, net of foreign tax credits, of $2.4 million . 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.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Effect of New Accounting Pronouncements	Effect of New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (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. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606), Deferral of the Effective Date.” With the issuance of ASU 2015-14, the new revenue guidance ASU 2014-09 will be effective for fiscal 2019, including interim periods within that reporting period, using one of two prescribed retrospective methods. In April 2016, the FASB issued ASU 2016-10, "Revenue from Contracts with Customer (Topic 606), Identifying Performance Obligations and Licensing." This ASU finalizes the amendments to the guidance on the new revenue standard on the identification of performance obligations and accounting for licenses of intellectual property. The Company is currently in the process of evaluating the impact of adoption on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-2, "Leases (Topic 842)," which supersedes the lease requirements in "Leases (Topic 840)." This ASU requires a lessee to recognize a right-of-use asset and a lease payment liability for most leases in the Consolidated Statement of Financial Position. This ASU also makes some changes to lessor accounting and aligns with the new revenue recognition guidance. This ASU will be effective for fiscal 2020, including interim periods within that reporting period, and earlier adoption is permitted. The Company is currently in the process of evaluating the impact of adoption on its consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU 2016-9, "Compensation-Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting." This ASU simplifies certain aspects of accounting for stock-based payment transactions, including the accounting for income taxes, provides an option to recognize gross stock-based compensation expense with actual forfeitures recognized as they occur and modifies the treatment of statutory tax withholding requirements, as well as certain classifications in the statement of cash flows. This ASU will be effective for fiscal 2018, including interim periods within that reporting period, and earlier adoption is permitted if all provisions are adopted in the same period. The Company is currently in the process of evaluating the impact of adoption on its consolidated financial statements and related disclosures.
