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 first fiscal quarters of fiscal 2016 and 2015 ended on January 30, 2016 and January 31, 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.

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 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. As of January 31, 2016 , the balances of our available-for-sale securities are: Cost Gross Gross Gross Estimated (in thousands) Cash equivalents: Money market funds $ 199,561 $ — $ — $ — $ 199,561 Commercial paper 1,199 — — — 1,199 Certificates of deposit 2,400 — — — 2,400 U.S. government agency securities 4,337 — — — 4,337 Total: $ 207,497 $ — $ — $ — $ 207,497 Short-term investments: U.S. government agency securities $ 13,718 $ 6 $ (6 ) $ — $ 13,718 Municipal bonds 1,402 1 — — 1,403 Certificates of deposit 8,297 — — — 8,297 Commercial paper 11,430 — — — 11,430 Corporate debt securities 65,160 8 (61 ) — 65,107 Asset-backed securities 22,009 5 (25 ) — 21,989 Non-U.S. government agency securities 1,006 — (2 ) — 1,004 Total: $ 123,022 $ 20 $ (94 ) $ — $ 122,948 (1) See Note 5.

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 1 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 2016 2015 (in thousands) Gain (loss) recorded in other income (expense), net $ (3,763 ) $ (2,758 ) The notional amounts in the table below for derivative instruments provide one measure of the transaction volume outstanding: As of January 31, 2016 As of October 31, 2015 (in thousands) Total gross notional amount $ 736,676 $ 781,752 Net fair value $ (16,412 ) $ (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. 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: Fair values of derivative instruments designated as hedging instruments Fair values of derivative instruments not designated as hedging instruments (in thousands) As of January 31, 2016 Other current assets $ 2,042 $ 1 Accrued liabilities $ 18,031 $ 424 As of October 31, 2015 Other current assets $ 6,461 $ 1 Accrued liabilities $ 10,141 $ 140 The following table represents the unaudited condensed consolidated statement of operations location and amount of gains and losses on derivative instrument fair values for designated hedge instruments, net of tax: Location of gain (loss) recognized in OCI on derivatives Amount of gain (loss) recognized in OCI on derivatives (effective portion) Location of gain (loss) reclassified from OCI Amount of gain (loss) reclassified from OCI (effective portion) (in thousands) Three months ended Foreign exchange contracts Revenue $ (1,491 ) Revenue $ 212 Foreign exchange contracts Operating expenses (11,268 ) Operating expenses (3,928 ) Total $ (12,759 ) $ (3,716 ) Three months ended Foreign exchange contracts Revenue $ 2,966 Revenue $ 2,381 Foreign exchange contracts Operating expenses (15,795 ) Operating expenses (3,436 ) Total $ (12,829 ) $ (1,055 ) The following table represents the ineffective portions and portions excluded from effectiveness testing of the hedge gains (losses) for derivative instruments designated as hedging instruments, which are recorded in other income (expense), net: Foreign exchange contracts Amount of gain (loss) recognized in income statement on derivatives (ineffective portion)(1) Amount of gain (loss) recognized in income statement on derivatives (excluded from effectiveness testing)(2) (in thousands) For the three months ended January 31, 2016 $ 254 $ 1,402 For the three months ended January 31, 2015 $ 740 $ 1,072 (1) The ineffective portion includes forecast inaccuracies.

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 .

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 months ended January 31, 2016 and 2015 , respectively. As of January 31, 2016 , the fair value of the Company’s non-marketable securities was $10.2 million , of which $6.6 million and $3.6 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.

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 January 31, 2016 , the Company is in compliance with all financial covenants. As of January 31, 2016 , the Company had a $37.5 million outstanding balance under the Term Loan and a $190.0 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 January 31, 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. 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 January 31, 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 included within stockholders' equity during fiscal 2015 and 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 (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 with an average purchase price of $46.08 per share. The remaining balance of $40.0 million is anticipated to be settled on or before April 29, 2016, upon completion of the repurchase. Under the terms of the December 2015 ASRs, 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 2016 2015 (in thousands) Total shares repurchased 3,849 3,290 Total cost of the repurchased shares(1) $ 180,000 $ 144,000 Reissuance of treasury stock 200 782 (1) The first quarter of fiscal 2016 includes the settlement of the $20.0 million equity forward contract related to the above-referenced August 2015 ASR and does not include the $40.0 million equity forward contract related to the above-referenced December 2015 ASRs.

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: Three Months Ended 2016 2015 (in thousands, except per share amounts) Numerator: Net income $ 60,035 $ 65,189 Denominator: Weighted-average common shares for basic net income per share 152,968 154,458 Dilutive effect of potential common shares from equity-based compensation 2,315 2,748 Weighted-average common shares for diluted net income per share 155,283 157,206 Net income per share: Basic $ 0.39 $ 0.42 Diluted $ 0.39 $ 0.41 Anti-dilutive employee stock-based awards excluded(1) 2,441 2,440 (1) These employee stock-based awards were anti-dilutive for the respective periods and are excluded in calculating diluted net income per share.

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 2016 2015 (in thousands) Revenue: United States $ 274,930 $ 277,587 Europe 71,935 71,883 Japan 53,246 60,852 Asia-Pacific and Other 168,493 131,721 Consolidated $ 568,604 $ 542,043 Geographic revenue data for multi-region, multi-product transactions reflect internal allocations and are therefore subject to certain assumptions and the Company’s methodology. One customer accounted for 12.2% and 11.3% of the Company’s unaudited condensed consolidated revenue in the three months ended January 31, 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 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 (benefit) for income taxes and the effective tax rates: Three Months Ended 2016 2015 (in thousands) Income before income taxes $ 64,342 $ 76,615 Provision (benefit) for income taxes $ 4,307 $ 11,426 Effective tax rate 6.7 % 14.9 % The Company’s effective tax rate for the three months ended January 31, 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 Company's effective tax rate decreased in the three months ended January 31, 2016 , as compared to the same period in fiscal 2015 , primarily due to the permanent reinstatement of the U.S. federal research tax credit, 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. However, U.S. Treasury has not withdrawn the requirement to include stock-based compensation from its regulations. Also, there is uncertainty related to the IRS response to the Tax Court opinion, the final resolution of this issue, and the potential favorable benefits to the Company. As such, no impact will be recorded at this time. The Company will continue to monitor developments related to this opinion and the potential impact of those developments on the Company’s current and prior fiscal years. The Company’s total gross unrecognized tax benefits at January 31, 2016 are $116.7 million exclusive of interest and penalties. If the total gross unrecognized tax benefits at January 31, 2016 were recognized in the future, approximately $113.9 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 $24 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 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.

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. The Company is currently in the process of evaluating the impact of adoption 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.
