Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Presentation	Basis of Presentation
	The accompanying unaudited Condensed Consolidated Financial Statements of Symantec Corporation (“Symantec,” “we,” “us,” “our,” and “the Company” refer to Symantec Corporation and all of its subsidiaries) as of January 2, 2015 and March 28, 2014, and for the three and nine months ended January 2, 2015 and December 27, 2013 have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S.”) for interim financial information and with the instructions on Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In accordance with those rules and regulations, we have omitted certain information and notes normally provided in our annual Consolidated Financial Statements. In the opinion of management, the unaudited Condensed Consolidated Financial Statements contain all adjustments, consisting only of normal recurring items, except as otherwise noted, necessary for the fair presentation of our financial position, results of operations, and cash flows for the interim periods. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in our Annual Report on Form 10-K for the fiscal year ended March 28, 2014. The results of operations for the three and nine months ended January 2, 2015 are not necessarily indicative of the results expected for the entire fiscal year.
	We have a 52/53-week fiscal accounting year. Unless otherwise stated, references to three and nine month ended periods in this report relate to fiscal periods ended January 2, 2015 and December 27, 2013. The nine months ended January 2, 2015 consisted of 40 weeks, whereas the nine months ended December 27, 2013 consisted of 39 weeks. Our 2015 fiscal year consists of 53 weeks and ends on April 3, 2015.
	There have been no material changes in our significant accounting policies for the three and nine months ended January 2, 2015, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended March 28, 2014. Certain immaterial amounts in our 2014 Condensed Consolidated Financial Statements within operating expenses have been reclassified to be comparable with classifications used in our 2015 Condensed Consolidated Financial Statements.
	The planned separation of Information Management from the Security Business
	On October 9, 2014, we announced plans to separate our business into two independent publicly-traded companies: one focused on security and one focused on information management. The transaction is intended to take the form of a tax-free distribution to Symantec shareholders of all of the capital stock of our information management business. We expect to complete the transaction by the end of December 2015, subject to market, regulatory and certain other conditions. John Gannon has been appointed as General Manager of the information management business, and Don Rath has been appointed as acting Chief Financial Officer. After the transaction, Michael Brown and Thomas Seifert will continue to lead Symantec as Chief Executive Officer and Chief Financial Officer, respectively. For additional cost information for restructuring actions being taken in connection with the planned separation, see Note 5.
	Segment reporting change
	In fiscal 2015, we are focused on managing our businesses as a portfolio and optimizing certain businesses for margin or growth. As a result, beginning from the second quarter of fiscal year 2015, we modified our segment reporting structure to match our new operating structure and how our Chief Operating Decision Maker ("CODM") reviews the business and allocates resources. The CODM function is comprised of our Chief Executive Officer and Chief Financial Officer. Reclassifications of prior period segment information have been made to conform to the current period presentation. This change does not impact our previously reported Condensed Consolidated Financial Statements. See Note 8 for additional information on our segment reporting change.
	Recently issued authoritative guidance
	On April 10, 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-08, Presentation of Financial Statements and Property, Plant and Equipment, that provides new guidance related to reporting discontinued operations. This new standard raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The new standard is effective for the Company April 4, 2015, and is expected to impact the treatment of the planned separation of our information management business that is expected to occur by the end of December 2015. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. We are evaluating the impact of adopting this new accounting guidance on our Condensed Consolidated Financial Statements and related disclosures.
	On May 28, 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers, that requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers, and will replace most existing revenue recognition guidance in U.S. GAAP. The new standard is effective for the Company April 1, 2017, and early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that the standard will have on our Condensed Consolidated Financial Statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.
	There was no other recently issued authoritative guidance that has a material impact to our Condensed Consolidated Financial Statements through the reporting date.

Fair_Value_Measurements

Fair Value Measurements	9 Months Ended
	Jan. 02, 2015
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	For assets and liabilities measured at fair value, such amounts are based on an expected exit price representing the amount that would be received on the sale of an asset or paid to transfer a liability, as the case may be, in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs, used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value:
	•	Level 1:  Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
	•	Level 2:  Observable inputs that reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.
	•	Level 3:  Unobservable inputs reflecting our own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.
	Assets measured and recorded at fair value on a recurring basis
	Cash equivalents. Cash equivalents consist of money market funds that are classified as Level 1, and corporate securities and commercial paper classified as Level 2, all of which have an original maturity of three months or less, and the carrying amount is a reasonable estimate of fair value.
	Short-term investments. Short-term investments consist of U.S. government securities with original maturities greater than three months and are classified as recurring Level 1. Also included in short-term investments are commercial paper, federal agency and corporate and international government securities with original maturities greater than three months, which are classified as Level 2. Short-term investments are priced using inputs such as actual trade data, benchmark yields, broker/dealer quotes, and other similar data, which are obtained from quoted market prices, independent pricing vendors, or other sources, to determine the fair value of these assets. Marketable equity securities are classified as Level 1 and are recorded at fair value using quoted prices in active markets for identical assets.
	There have been no transfers between fair value measurement levels during the nine months ended January 2, 2015. The following table summarizes our assets measured at fair value on a recurring basis, by level, within the fair value hierarchy:
		January 2, 2015						March 28, 2014

	(1)  Additions due to an acquired business.
	(2)  Adjustments made to goodwill reflect foreign currency exchange rate fluctuations.
	Effective in the second quarter of fiscal 2015, we evaluated our segment reporting structure and modified the reporting to match our new operating structure. Our reporting units for goodwill are the same as our reportable operating segments, and the net goodwill balance has been allocated to the reporting units based on their relative fair value. See Note 8 for information regarding the changes related to segment information.
	As a result of the change in our segments, we assessed goodwill for impairment immediately prior to the changes to the new reporting units and determined that the estimated fair value of our reporting units exceeded their respective carrying amount including goodwill. Based on the results of our impairment analysis, we do not believe that impairment existed as of the date of the change in our segments.

Restructuring and Related Activities [Abstract]
Restructuring, Separation, And Transition	Restructuring, Separation, and Transition
	Our restructuring, separation, and transition costs and liabilities consist primarily of severance, facilities, separation, transition and other related costs. Severance costs generally include severance payments, outplacement services, health insurance coverage, and legal costs. Facilities costs generally include rent expense and lease termination costs, less estimated sublease income. Separation and other related costs will include advisory, consulting and other costs incurred in connection with the separation of our information management business. Transition and other related costs consist of consulting charges associated with the implementation of new Enterprise Resource Planning systems. Restructuring, separation, and transition costs are managed at the corporate level and are not allocated to our reportable segments. See Note 8 of these Condensed Consolidated Financial Statements for information regarding the reconciliation of total segment operating income to total consolidated operating income.
	Restructuring plans
	Fiscal 2014 Plan
	We initiated a restructuring plan in the fourth quarter of fiscal 2013 to reduce management and redundant personnel resulting in headcount reductions across the Company. As of January 2, 2015, the related costs for severance and benefits are substantially complete, however we expect to incur immaterial adjustments to existing reserves in subsequent periods.
	Fiscal 2015 Plan
	Our Board of Directors has approved the strategic decision to separate our business into two independent publicly-traded companies: one focused on security and one focused on information management. We expect to complete this transaction by the end of December 2015, subject to market, regulatory and certain other conditions. In order to separate the business, we initiated a restructuring plan to properly align personnel and expect to incur associated severance and facilities costs. We also expect to incur separation costs in the form of advisory, consulting and disentanglement expenses. These actions are expected to be completed in fiscal 2016. We expect to incur total severance and facilities costs between $100 million and $120 million, more than half of which is expected to be incurred in fiscal 2015. We expect to incur separation costs between $80 million and $100 million, excluding any potential tax implications outside the U.S and potential advisor fees payable upon separation. Total restructuring and separation costs are expected to be between $180 million and $220 million. As of January 2, 2015, liabilities for excess facility obligations at several locations around the world are expected to be paid throughout the respective lease terms as we continue to occupy these facilities, the longest of which extends through fiscal 2016.

	Indemnification
	In the ordinary course of business, we may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners, subsidiaries and other parties with respect to certain matters, including, but not limited to, losses arising out of our breach of agreements or representations and warranties made by us. In addition, our bylaws contain indemnification obligations to our directors, officers, employees and agents, and we have entered into indemnification agreements with our directors and certain of our officers to give such directors and officers additional contractual assurances regarding the scope of the indemnification set forth in our bylaws and to provide additional procedural protections. We maintain director and officer insurance, which may cover certain liabilities arising from our obligation to indemnify our directors and officers. It is not possible to determine the aggregate maximum potential loss under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Such indemnification agreements might not be subject to maximum loss clauses. Historically, we have not incurred material costs as a result of obligations under these agreements and we have not accrued any liabilities related to such indemnification obligations in our Condensed Consolidated Financial Statements.
	We provide limited product warranties and the majority of our software license agreements contain provisions that indemnify licensees of our software from damages and costs resulting from claims alleging that our software infringes on the intellectual property rights of a third party. Historically, payments made under these provisions have been immaterial. We monitor the conditions that are subject to indemnification to identify if a loss has occurred.
	Litigation contingencies
	During the first quarter of fiscal 2013, we were advised by the Commercial Litigation Branch of the Department of Justice’s Civil Division and the Civil Division of the U.S. Attorney’s Office for the District of Columbia that the government is investigating our compliance with certain provisions of our U.S. General Services Administration (“GSA”) Multiple Award Schedule Contract No. GS-35F-0240T effective January 24, 2007, including provisions relating to pricing, country of origin, accessibility, and the disclosure of commercial sales practices.
	As reported on the GSA’s publicly-available database, our total sales under the GSA Schedule contract were approximately $222 million from the period beginning January 2007 and ending September 2012. We have fully cooperated with the government throughout its investigation and in January 2014, representatives of the government indicated that their initial analysis of our actual damages exposure from direct government sales under the GSA schedule is approximately $145 million; since the initial meeting, the government’s analysis of our potential damages exposure relating to direct sales has increased. The government has also indicated they are going to pursue claims for certain sales to New York, California, and Florida as well as sales to the federal government through reseller GSA Schedule contracts, which could significantly increase our potential damages exposure.
	In 2012, a sealed civil lawsuit was filed against Symantec related to compliance with the GSA Schedule contract and contracts with California, Florida, and New York. On July 18, 2014, the Court-imposed seal expired, and the government intervened in the lawsuit. On September 16, 2014, the states of California and Florida intervened in the lawsuit, and the state of New York notified the Court that it would not intervene. On October 3, 2014, the Department of Justice filed an amended complaint, which did not state a specific damages amount. On October 17, 2014, California and Florida combined their claims with those of the Department of Justice and the relator on behalf of New York in an Omnibus Complaint; the state claims also do not state specific damages amounts.
	It is possible that the litigation could lead to claims or findings of violations of the False Claims Act, and could be material to our results of operations and cash flows for any period. Resolution of False Claims Act investigations can ultimately result in the payment of somewhere between one and three times the actual damages proven by the government, plus civil penalties in some cases, depending upon a number of factors. Our current estimate of the low end of the range of the probable estimated loss from this matter is $25 million, which we have accrued. This amount contemplates estimated losses from both the investigation of compliance with the terms of the GSA Schedule contract as well as possible violations of the False Claims Act. There is at least a reasonable possibility that a loss may have been incurred in excess of our accrual for this matter, however, we are currently unable to determine a range of estimated losses resulting from this matter.
	We are also involved in a number of other judicial and administrative proceedings that are incidental to our business. Although adverse decisions (or settlements) may occur in one or more of the cases, it is not possible to estimate the possible loss or losses from each of these cases. The final resolution of these lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on our business, results of operations, financial condition or cash flow.

Segment Reporting [Abstract]
Segment Information	Segment Information
	In fiscal 2015, we are focused on managing our businesses as a portfolio and optimizing certain businesses for margin or growth. As a result, in the second quarter of fiscal 2015 we formed a new consumer group and modified our segment reporting structure to match our operating structure based on financial information reviewed by our CODM. Consumer Security consists of our consumer businesses that were previously reported in User Productivity & Protection. Enterprise Security consists of our enterprise security businesses that were previously reported in User Productivity & Protection and Information Security. Our Information Management segment was not impacted by the change in our operating structure. The three reporting segments, which are the same as our operating segments, are as follows:
	•	Consumer Security: Our Consumer Security segment focuses on making it simple for customers to be productive and protected at home and at work. Our Norton-branded services provide multi-layer security and identity protection on major desktop and mobile operating systems, to defend against increasingly complex online threats to individuals, families, and small businesses.
	•	Enterprise Security: Our Enterprise Security segment protects organizations so they can securely conduct business while leveraging new platforms and data. These products include our Secure Socket Layer ("SSL") Certificates, authentication, mail and web security, data center security, data loss prevention, information security services, endpoint security and management, encryption, and mobile offerings.
	•	Information Management: Our Information Management segment focuses on backup and recovery, archiving and eDiscovery, storage and high availability solutions, ensuring that our customers’ IT infrastructure and mission-critical applications are protected, managed and available.
	There were no intersegment sales during the three and nine months ended January 2, 2015 or December 27, 2013. Reclassifications of prior period information have been made to conform to the current period presentation. The following table summarizes the operating results of our reporting segments:

	Operating income	673		245		471		1,389
	Operating segments are based upon the nature of the business and how the business is managed. Our CODM uses financial information to evaluate the performance of, and to assign resources to, each of the operating segments. We do not allocate to the operating segments certain operating expenses, which we manage separately at the corporate level. These unallocated costs can include stock-based compensation expense, amortization of intangible assets, restructuring, separation, and transition charges, and acquisition-related charges.
	The reconciliation of total segment operating income to total consolidated operating income is as follows:

	Our Board of Directors appointed Michael A. Brown as our new President and Chief Executive Officer ("CEO"), effective September 24, 2014. During the second quarter of fiscal 2015, we granted 344,717 performance-based restricted stock units, ("PRUs") to our new CEO which had a fair value of $11 million. These PRUs are subject to vesting based on the Company’s achievement of (1) targeted non-GAAP earnings per share for fiscal 2015 and (2) the achievement of the total shareholder return ranking for the Company as compared to the S&P 500 for the 2 year period ending at the end of fiscal 2016 and for the three year period ending at the end of fiscal 2017. The fair value of these PRUs was calculated using a Monte Carlo simulation option pricing model. Additionally, we granted 147,736 restricted stock units (“RSUs”) to Mr. Brown that will vest in three annual installments beginning on September 1, 2015. The compensation expense is amortized ratably over the requisite service period.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes
	The effective tax rate was approximately 29% and 26% for the three and nine months ended January 2, 2015, and 27% and 21% for the three and nine months ended December 27, 2013, respectively.
	For the three and nine months ended January 2, 2015, the tax expense was reduced by $8 million and $28 million, respectively, in tax benefits primarily resulting from tax settlements, lapses of statutes of limitations, and prior year items. The tax provision was also reduced by $2 million in tax benefits for the three and nine months ended January 2, 2015 resulting from the extension of the U.S. federal research and development tax credit through 2014 ("R&D credit") as part of the Tax Increase Prevention Act of 2014. There was no benefit to the tax provision, in the three and nine months ended January 2, 2015, resulting from separation costs incurred in these periods.
	For the three and nine months ended December 27, 2013, the tax provision was reduced by a net tax benefit of $7 million related to certain foreign operations. The tax provision for the three and nine months ended December 27, 2013 was also reduced by $2 million and $13 million in tax benefits, respectively, primarily resulting from individually insignificant tax settlements, lapses of statutes of limitations, and prior year items. For the nine months ended December 27, 2013, the tax provision was further reduced by $33 million for the resolution of a tax matter related to the sale of our 49% ownership interest in the joint venture with Huawei during the fourth quarter of fiscal 2012, as well as by $24 million for tax benefits related to the settlement of the Symantec 2005 through 2008 Internal Revenue Service (“IRS”) audit. These tax benefits were partially offset by $12 million in tax expense, in the nine months ended December 27, 2013, resulting from the sale of short-term investments.
	The provision for the three and nine months ended January 2, 2015 and December 27, 2013 otherwise reflects a forecasted tax rate of 28% and 29%, for each period, respectively. The forecasted tax rates for all periods presented reflect the benefits of lower-taxed international earnings and domestic manufacturing incentives, and the R&D credit, partially offset by state income taxes. The forecasted tax rate for the period ended January 2, 2015 includes the partial benefit of the R&D credit which expired on December 31, 2014.
	We are a U.S.-based multinational company subject to tax in multiple U.S. and international tax jurisdictions. A substantial portion of our international earnings were generated from subsidiaries organized in Ireland and Singapore. Our results of operations would be adversely affected to the extent that our geographical mix of income becomes more weighted toward jurisdictions with higher tax rates and would be favorably affected to the extent the relative geographic mix shifts to lower tax jurisdictions. Any change in our mix of earnings is dependent upon many factors and is therefore difficult to predict.
	The timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. Although potential resolution of uncertain tax positions involve multiple tax periods and jurisdictions, it is reasonably possible that the gross unrecognized tax benefits related to these audits could decrease, whether by payment, remeasurement, and/or release in the next 12 months, by between $30 million and $150 million. Depending on the nature and timing of such settlements and expiration of statutes of limitations during the next 12 months, we estimate between $15 million and $70 million could affect our income tax provision and therefore benefit the resulting effective tax rate. As of January 2, 2015, we have $127 million on deposit with the IRS pertaining to U.S. tax matters in the Symantec fiscal 2009 through 2013 audit cycle, and it is reasonably possible that additional cash payments between $15 million and $65 million will be made in the next 12 months.
	We continue to monitor the progress of ongoing tax controversies and the impact, if any, of the expected expiration of the statute of limitations in various taxing jurisdictions.

	On February 3, 2015, our Board of Directors authorized a new $1.0 billion stock repurchase program which commenced immediately and does not have an expiration date. This is in addition to the previous program with $283 million remaining authorized for future repurchase.
	On December 8, 2010, Intellectual Ventures ("IV") sued Symantec for patent infringement in the U.S. District Court in Delaware. The complaint alleged infringement of four patents by various Symantec internet security products, including Norton security products, Symantec Endpoint Protection, and other Symantec email and web security products. In January 2014, one patent was dismissed from the case. On January 26, 2015, a jury trial began on the remaining three patents. At trial, IV requested a damages award of up to $299 million. Symantec offered evidence that the three patents were invalid and not infringed. Symantec also offered evidence that, even if any of the patents are found to be valid and infringed, any damages would be significantly lower than the amount requested by IV.  After a nine-day trial, on February 6, 2015, the jury issued a verdict finding that:  two of the three patents are valid and infringed and awarded damages in the amount of $17 million.  Symantec is considering its options to overturn all or part of the verdict, including the filing of post-trial motions for judgment as a matter of law and/or a motion for a new trial and/or filing an appeal to the Federal Circuit. Symantec does not believe that it is probable that it has incurred a material loss and, as a result, has not made an accrual for this matter.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	The accompanying unaudited Condensed Consolidated Financial Statements of Symantec Corporation (“Symantec,” “we,” “us,” “our,” and “the Company” refer to Symantec Corporation and all of its subsidiaries) as of January 2, 2015 and March 28, 2014, and for the three and nine months ended January 2, 2015 and December 27, 2013 have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S.”) for interim financial information and with the instructions on Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In accordance with those rules and regulations, we have omitted certain information and notes normally provided in our annual Consolidated Financial Statements. In the opinion of management, the unaudited Condensed Consolidated Financial Statements contain all adjustments, consisting only of normal recurring items, except as otherwise noted, necessary for the fair presentation of our financial position, results of operations, and cash flows for the interim periods. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in our Annual Report on Form 10-K for the fiscal year ended March 28, 2014. The results of operations for the three and nine months ended January 2, 2015 are not necessarily indicative of the results expected for the entire fiscal year.
	We have a 52/53-week fiscal accounting year. Unless otherwise stated, references to three and nine month ended periods in this report relate to fiscal periods ended January 2, 2015 and December 27, 2013. The nine months ended January 2, 2015 consisted of 40 weeks, whereas the nine months ended December 27, 2013 consisted of 39 weeks. Our 2015 fiscal year consists of 53 weeks and ends on April 3, 2015.
	There have been no material changes in our significant accounting policies for the three and nine months ended January 2, 2015, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended March 28, 2014. Certain immaterial amounts in our 2014 Condensed Consolidated Financial Statements within operating expenses have been reclassified to be comparable with classifications used in our 2015 Condensed Consolidated Financial Statements.
	The planned separation of Information Management from the Security Business
	On October 9, 2014, we announced plans to separate our business into two independent publicly-traded companies: one focused on security and one focused on information management. The transaction is intended to take the form of a tax-free distribution to Symantec shareholders of all of the capital stock of our information management business. We expect to complete the transaction by the end of December 2015, subject to market, regulatory and certain other conditions. John Gannon has been appointed as General Manager of the information management business, and Don Rath has been appointed as acting Chief Financial Officer. After the transaction, Michael Brown and Thomas Seifert will continue to lead Symantec as Chief Executive Officer and Chief Financial Officer, respectively. For additional cost information for restructuring actions being taken in connection with the planned separation, see Note 5.
Segment reporting change	In fiscal 2015, we are focused on managing our businesses as a portfolio and optimizing certain businesses for margin or growth. As a result, beginning from the second quarter of fiscal year 2015, we modified our segment reporting structure to match our new operating structure and how our Chief Operating Decision Maker ("CODM") reviews the business and allocates resources. The CODM function is comprised of our Chief Executive Officer and Chief Financial Officer. Reclassifications of prior period segment information have been made to conform to the current period presentation. This change does not impact our previously reported Condensed Consolidated Financial Statements. See Note 8 for additional information on our segment reporting change.
Recently issued authoritative guidance	On April 10, 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-08, Presentation of Financial Statements and Property, Plant and Equipment, that provides new guidance related to reporting discontinued operations. This new standard raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The new standard is effective for the Company April 4, 2015, and is expected to impact the treatment of the planned separation of our information management business that is expected to occur by the end of December 2015. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. We are evaluating the impact of adopting this new accounting guidance on our Condensed Consolidated Financial Statements and related disclosures.
	On May 28, 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers, that requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers, and will replace most existing revenue recognition guidance in U.S. GAAP. The new standard is effective for the Company April 1, 2017, and early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that the standard will have on our Condensed Consolidated Financial Statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.
	There was no other recently issued authoritative guidance that has a material impact to our Condensed Consolidated Financial Statements through the reporting date.
