Basis of Presentation

Basis of Presentation [Abstract]
Basis of Presentation	Basis of Presentation Computer Sciences Corporation (CSC or the Company) has prepared the interim unaudited Condensed Consolidated Financial Statements included herein pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for quarterly reports and, therefore, omit or condense certain note disclosures and other information required by generally accepted accounting principles in the United States (GAAP) for complete financial statements. These financial statements should therefore be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company's Annual Report on Form 10-K for the fiscal year ended April 1, 2016 (fiscal 2016 ). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts and disclosures reported in the financial statements and accompanying notes. As a result, actual results may be different from these estimates. In the opinion of the Company's management, the accompanying unaudited Condensed Consolidated Financial Statements of CSC contain all adjustments necessary, including those of a normal recurring nature, to present fairly the Company's financial position as of July 1, 2016 and April 1, 2016 and its results of operations and cash flows for the three months ended July 1, 2016 and July 3, 2015 . The results of operations for such interim periods are not necessarily indicative of the results for the full year ending March 31, 2017 . Certain prior year amounts have been reclassified to conform to the current year presentation. During fiscal 2016 , the Company adopted ASU 2016-09 which, among other elements, requires the excess tax benefits and deficiencies related to employee share-based payment awards and related dividends to be recorded in the statement of operations during the reporting period in which they occur. ASU 2016-09 also requires that all tax-related cash flows resulting from share-based payments, including the excess tax benefits related to the settlement of stock-based awards, be classified as cash flows from operating activities, and that cash paid by directly withholding shares for tax withholding purposes be classified as a financing activity in the unaudited Condensed Consolidated Statements of Cash Flows. CSC elected to early adopt ASU 2016-09 in the fourth quarter of fiscal 2016 which requires us to reflect any adjustments as of April 4, 2015, the beginning of the annual period that includes the adoption. Amendments requiring recognition of excess tax benefits and tax deficiencies within the unaudited Condensed Consolidated Statements of Operations were adopted prospectively and resulted in the recognition of $14 million , or $0.10 per share, of excess tax benefits within income tax (benefit) expense for the three months ended July 3, 2015. ASU 2016-09 amendments related to presentation within the Consolidated Statements of Cash Flows were applied retrospectively, and resulted in the reclassification of $14 million of excess tax benefits related to the settlement of stock-based awards from financing to operating activities, and $24 million of taxes paid related to net share settlements of stock-based compensation awards from operating activities to financing activities for the three months ended July 3, 2015 . The Company reports its results based on a fiscal year convention that comprises four thirteen-week quarters. Every fifth year includes an additional week in the first quarter to prevent the fiscal year from moving from an approximate end of March date. Separation of NPS During fiscal 2016, the Company completed the separation of its U.S. public sector business (NPS) (the Separation) and merger of NPS with SRA International to form a new independent publicly traded Company: CSRA Inc. (CSRA). As a result of the Separation, the unaudited Condensed Consolidated Statements of Operations and related financial information reflect NPS's operations as discontinued operations for the first three months of fiscal 2016. However, the cash flows and comprehensive income of NPS have not been segregated and are included in the unaudited Condensed Consolidated Statements of Cash Flows and Statements of Comprehensive Income for the first three months of fiscal 2016. Furthermore, CSC reduced the number of its reportable segments from three to two : Global Infrastructure Services (GIS) and Global Business Services (GBS). Refer to Note 4 Divestitures and Note 15 Segment Information for further information.

Recent Accounting Pronouncement

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements New Accounting Standards During the first three months of fiscal 2017 , the Company adopted the following Accounting Standard Updates (ASUs): ASU 2015-16, Business Combinations (Topic 805), "Simplifying the Accounting for Measurement Period Adjustments" requires an acquirer in a business combination to account for a measurement-period adjustment during the period in which the amount is determined, instead of retrospectively. CSC adopted this ASU effective April 2, 2016 and has not had any measurement-period adjustments since adoption. As a result, there has been no impact to CSC's financial statements. ASU 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs" as clarified by ASU 2015-15, "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements—Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting" (ASU 2015-15) states that debt issuance costs are presented in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Presentation of fees under line of credit (LOC) arrangements had not been specified in this ASU; as a result, ASU 2015-15 was issued. ASU 2015-15 states that the SEC staff would not object to an entity deferring LOC commitment fees as an asset and subsequently amortizing ratably over the term of the underlying LOC arrangement, regardless of whether there are outstanding borrowings under that LOC arrangement. CSC adopted both ASUs effective April 2, 2016 and the impact upon the unaudited Condensed Consolidated Financial Statements was immaterial. ASU 2015-05, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement" issued guidance about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement does not contain a software license, the customer should account for the arrangement as a service contract. If the arrangement includes software licenses, it should be accounted for consistent with other licenses of intangible assets. CSC elected to adopt this ASU prospectively effective April 2, 2016. Adoption of this ASU did not have a material impact on the unaudited Condensed Consolidated Financial Statements. Standards Issued But Not Yet Effective The following ASUs were recently issued but have not yet been adopted by CSC: In June 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): "Measurement of Credit Losses on Financial Instruments", which is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this update replace the existing incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 will be effective for CSC in fiscal 2020. This ASU must be adopted using a prospective transition approach for debt securities for which an other-than-temporary impairment had been recognized before the effective date. CSC is currently evaluating the impact of the adoption of ASU 2016-13 may have on its unaudited Condensed Consolidated Financial Statements in future reporting periods. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)". This amendment is intended to increase transparency and comparability among organizations by recognizing virtually all lease assets and lease liabilities on the balance sheet and disclosing key information about lease arrangements. ASU 2016-02 will be effective for CSC in fiscal 2020 and early adoption is permitted. This ASU must be adopted using a modified retrospective transition and provides for certain practical expedients. CSC is currently evaluating the impact that the adoption of ASU 2016-02 may have on its unaudited Condensed Consolidated Financial Statements in future reporting periods. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities", which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 will be effective for CSC in fiscal 2019. This ASU should be applied prospectively to equity investments that exist as of the date of adoption for equity securities without readily determinable fair values. CSC is currently evaluating the impact of the adoption of ASU 2016-01 may have on CSC's unaudited Condensed Consolidated Financial Statements in future reporting periods. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (ASU 2014-09). ASU 2014-09 supersedes the revenue recognition requirements in ASC Topic 605, “Revenue Recognition” and some cost guidance included in ASC Subtopic 605-35, "Revenue Recognition - Construction-Type and Production-Type Contracts.” The core principle of ASU 2014-09 is that revenue is recognized when the transfer of goods or services to customers occurs in an amount that reflects the consideration to which CSC expects to be entitled in exchange for those goods or services. ASU 2014-09 requires the disclosure of sufficient information to enable readers of CSC’s financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09 also requires disclosure of information regarding significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 provides two methods of retrospective application. The first method would require CSC to apply ASU 2014-09 to each prior reporting period presented. The second method would require CSC to retrospectively apply ASU 2014-09 with the cumulative effect recognized at the date of initial application. ASU 2014-09 will be effective for CSC beginning in fiscal 2019 as a result of ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date" (ASU 2015-14) which was issued by the FASB in August 2015 and extended the original effective date by one year. CSC is currently evaluating the impact of adopting the available methodologies of ASU 2014-09 and 2015-14 upon its unaudited Condensed Consolidated Financial Statements in future reporting periods. There have been three new ASUs issued amending certain aspects of ASU 2014-09. ASU 2016-08 "Principal versus Agent Considerations (Reporting Revenue Gross Versus Net)," was issued in March, 2016 to clarify certain aspects of the principal versus agent guidance in ASU 2014-09. In addition, ASU 2016-10 "Identifying Performance Obligations and Licensing" issued in April 2016, amends other sections of ASU 2014-09 including clarifying guidance related to identifying performance obligations and licensing implementation. Finally, ASU 2016-12, "Revenue from Contracts with Customers - Narrow Scope Improvements and Practical Expedients" provides amendments and practical expedients to the guidance in ASU 2014-09 in the areas of assessing collectability, presentation of sales taxes received from customers, noncash consideration, contract modification and clarification of using the full retrospective approach to adopt ASU 2014-09. With its evaluation of the impact of ASU 2014-09, CSC will also consider the impact related to the updated guidance provided by these three new ASUs. Other recently issued ASUs effective after July 1, 2016 are not expected to have a material effect on CSC's unaudited Condensed Consolidated Financial Statements in future reporting periods.

Acquisitions

Business Combinations [Abstract]
Acquisitions	Acquisitions Fiscal 2017 Acquisition Xchanging Acquisition On December 29, 2015, CSC invested in Xchanging plc (Xchanging), a provider of technology-enabled business solutions to organizations in global insurance and financial services, healthcare, manufacturing, real estate and the public sector. Xchanging was listed on the London Stock Exchange under the symbol “XCH”. CSC purchased 24,636,553 shares of common stock of Xchanging for a purchase price of $2.83 per share for a total initial investment of approximately $70 million . The investment represented a 9.99% non-controlling equity interest in the outstanding shares of Xchanging. On May 5, 2016, CSC acquired the remaining shares of Xchanging, for a purchase price of $2.76 per share, or approximately $623 million , resulting in total cash consideration paid to and on behalf of the Xchanging shareholders of $693 million (or $492 million net of cash acquired) in the aggregate, which was funded from existing cash balances and borrowings under our $2.9 billion credit facility. Subsequent to the acquisition, the Company repaid the $254 million of acquired debt. Transaction costs associated with the acquisition of $17 million are included within selling, general and administrative expenses in the Company's unaudited Condensed Consolidated Statements of Operations. The acquisition will expand CSC's market coverage in the global insurance industry and will enable the Company to offer access to a broader, partner-enriched portfolio of services including property and casualty insurance and wealth management business processing services.

Discontinued Operations and Disposal Groups [Abstract]
Divestitures	Divestitures During fiscal 2016, the Company completed the separation of NPS. As a result, the operating results for NPS were reclassified to discontinued operations. The following table details the components of discontinued operations: Three months ended (in millions) July 3, 2015 Revenues $ 957 Costs of services (754 ) Selling, general and administrative (16 ) Depreciation and amortization (33 ) Separation and merger costs (15 ) Interest expense (5 ) Other income, net 22 Total income from discontinued operations, before income taxes 156 Income tax expense (54 ) Total income from discontinued operations $ 102 There was no gain or loss on disposition recognized as a result of the Separation. The following selected financial information of NPS is included in the unaudited Condensed Consolidated Statements of Cash Flows: Three months ended (in millions) July 3, 2015 Depreciation $ 28 Amortization $ 5 Capital expenditures $ (16 ) Significant operating non-cash items: Net gain on disposition of business $ 22 Significant investing non-cash items: Capital expenditures in accounts payable $ (9 ) J. Michael Lawrie currently serves as CSC's Chief Executive Officer and as a member of its Board of Directors. Since the Separation became effective on November 27, 2015, Mr. Lawrie also has served as Chairman of the Board of Directors of CSRA. Due to Mr. Lawrie's leadership positions at the Company and CSRA, CSRA is considered a related party under ASC 850 "Related Party Disclosures." On June 23, 2016, Mr. Lawrie announced that he will resign as chairman and as a member of the board of directors of CSRA on August 9, 2016 at CSRA's scheduled annual meeting. Implementation of the Separation and CSC's post-Separation relationship with CSRA is governed by several agreements, including a master separation and distribution agreement and intellectual property (IP) matters, real estate matters, tax matters, non-U.S. agency and employee matters agreements. Pursuant to the IP matters agreement, which grants CSRA perpetual, royalty-free, non-assignable licenses to certain software products, trademarks and workflow and design methodologies owned by CSC, CSRA agreed to pay CSC an annual net maintenance fee of $30 million per year for each of the five years following the Separation in exchange for maintenance services. Under the IP matters agreement, CSC recognized $8 million of related party revenue in its unaudited Condensed Consolidated Statements of Operations for the three months ended July 1, 2016 . An additional $12 million is included in deferred revenue and advance contract payments on CSC's unaudited Condensed Consolidated Balance Sheets as of July 1, 2016 , which will be amortized to revenue over the two successive quarters. In addition, CSC is also party to various other commercial agreements with CSRA totaling $13 million of revenue during the three months ended July 1, 2016 . As of July 1, 2016 , related party accounts receivable of approximately $23 million was due from CSRA.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per common share (EPS) and diluted EPS are calculated as follows: Three months ended (in millions, except per-share amounts) July 1, 2016 July 3, 2015 (1) Net income attributable to CSC common stockholders From continuing operations $ (21 ) $ 65 From discontinued operations — 98 $ (21 ) $ 163 Common share information: Weighted average common shares outstanding for basic EPS 138.98 137.92 Dilutive effect of stock options and equity awards — 3.47 Weighted average common shares outstanding for diluted EPS 138.98 141.39 Earnings per share – basic and diluted: Basic EPS: Continuing operations $ (0.15 ) $ 0.47 Discontinued operations — 0.71 Total $ (0.15 ) $ 1.18 Diluted EPS: Continuing operations $ (0.15 ) $ 0.46 Discontinued operations — 0.69 Total $ (0.15 ) $ 1.15 (1) The Company adopted ASU 2016-09 during the fourth quarter of fiscal 2016 , effective as of the beginning of the fiscal year. As a result, weighted average diluted shares outstanding has been adjusted from the amount previously reported for the three months ended July 3, 2015 to exclude excess tax benefits from the assumed proceeds in the diluted shares calculation. The adoption of this standard resulted in diluted weighted average shares outstanding of 141.39 million for the three months ended July 3, 2015 versus 140.80 million as calculated under the previous guidance. Stock options and RSUs with an exercise price greater than the average market price of the shares for the full year would have been anti-dilutive, and therefore were excluded from the diluted earnings per share computation. For the three months ended July 1, 2016 , stock options of 1,507,757 , performance stock units of 1,070,917 and restricted stock units (RSUs) of 876,785 were excluded from the computation of diluted EPS due to the Company's net loss. For the three months ended July 3, 2015 , stock options of 1,534,173 and RSUs of 80,994 were excluded in the computation of diluted EPS, which if included, would have been anti-dilutive.

The balance sheet classifications of the Company's derivative instruments are presented in Note 7 Derivative Instruments . There were no transfers between any of the levels during the periods presented. Financial instruments not measured at fair value The carrying amounts of the Company’s financial instruments with short-term maturities are deemed to approximate their market values. As of July 1, 2016 , the carrying amount of the Company’s long-term debt, excluding capital leases, and the estimated fair value was $2.5 billion . The fair value of long-term debt is estimated based on current interest rates offered to the Company for instruments with similar terms and remaining maturities and classified as Level 2. The Company is subject to counterparty risk in connection with its derivative instruments (see Note 7 Derivative Instruments ). With respect to its foreign currency derivatives, as of July 1, 2016 there were five counterparties with concentration of credit risk. Based on gross fair value of these foreign currency derivative instruments, the maximum amount of loss that the Company could incur is approximately $43 million . The Company’s credit risk is also affected by customers in bankruptcy proceedings; however, because most of these proceedings involve business reorganizations rather than liquidations and the nature of the Company’s services are often considered essential to the operational continuity of these customers, the Company is generally able to avoid or mitigate significant adverse financial impact in these cases. As of July 1, 2016 , the Company had $17 million of accounts receivable, $11 million of related allowance for doubtful accounts, $1 million of other assets and $4 million of accounts payable with customers involved in bankruptcy proceedings.

These instruments were designated as cash flow hedges of the variability of cash outflows for interest payments on certain floating interest rate debt, which effectively converted the debt into fixed interest rate debt. The Company has designated certain foreign currency forward contracts as cash flow hedges, to reduce risks related to certain Indian Rupee denominated intercompany obligations and forecasted transactions. The notional amount of foreign currency forward contracts designated as cash flow hedges as of July 1, 2016 was $418 million and the related forecasted transactions extend through March 2018 . For the three months ended July 1, 2016 , the Company performed an assessment at the inception of the cash flow hedge transactions that determined all critical terms of the hedging instruments and hedged items match; therefore, there is no ineffectiveness to be recorded and all changes in the hedging instruments’ fair value are recorded in accumulated other comprehensive loss (OCI) and subsequently reclassified into earnings in the period during which the hedged transactions are recognized in earnings. The Company performs an assessment of critical terms on an on-going basis throughout the hedging period. During the three months ended July 1, 2016 , the Company had no cash flow hedges for which it was probable that the hedged transaction would not occur. As of July 1, 2016 , approximately $5 million of the existing losses related to the cash flow hedges reported in accumulated OCI are expected to be reclassified into earnings within the next 12 months. Derivatives not designated for hedge accounting Foreign currency derivatives The Company manages exposure to fluctuations in foreign currencies by using short-term foreign currency forward contracts to economically hedge certain foreign currency denominated assets and liabilities, including intercompany accounts and loans. For accounting purposes, these foreign currency option and forward contracts are not designated as hedges, as defined under ASC 815, “Derivatives and Hedging,” and all changes in their fair value are reported in current period earnings within the other income (expense) line of the unaudited Consolidated Condensed Statements of Operations. The notional amount of the foreign currency forward contracts outstanding as of July 1, 2016 was $2.0 billion . The following table presents the amounts included within income from continuing operations, before taxes not designated for hedge accounting, net of remeasurement gains and losses: Three Months Ended (in millions) Statement of Operations line item July 1, 2016 July 3, 2015 Foreign currency forwards Other Income (Expense), net $ (2 ) $ 3 Other risks As discussed further in Note 7 Derivative Instruments , the Company is exposed to the risk of losses in the event of non-performance by the counterparties to its derivative contracts. To mitigate counterparty credit risk, the Company regularly reviews its credit exposure and the creditworthiness of the counterparties. The Company also enters into enforceable master netting arrangements with some of its counterparties. However, for financial reporting purposes it is the Company’s policy to not offset derivative assets and liabilities despite the existence of enforceable master netting arrangements with some of its counterparties.

Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill The following table summarizes the changes in the carrying amount of goodwill by segment for the three months ended July 1, 2016 : (in millions) GBS GIS Total Goodwill, gross $ 1,615 $ 2,424 $ 4,039 Accumulated impairment losses (701 ) (2,061 ) (2,762 ) Balance as of April 1, 2016, net 914 363 1,277 Additions 590 31 621 Foreign currency translation (77 ) (4 ) (81 ) Goodwill, gross 2,128 2,451 4,579 Accumulated impairment losses (701 ) (2,061 ) (2,762 ) Balance as of July 1, 2016, net $ 1,427 $ 390 $ 1,817 The fiscal 2017 additions to goodwill are due to the acquisition of Xchanging. The foreign currency translation amount reflects the impact of currency movements on non-U.S. dollar-denominated goodwill balances. The Company tests goodwill for impairment on an annual basis, as of the first day of the second fiscal quarter. An impairment test is also performed if an event occurs, or circumstances change, that would more likely than not reduce the fair value of a reporting unit below its carrying amount. At the end of the first three months of fiscal 2017 , the Company assessed whether there were events or changes in circumstances that would more likely than not reduce the fair value of any of its reporting units below their carrying amount. The Company concluded that there have been no such indicators and, therefore, it was unnecessary to perform an interim goodwill impairment test as of July 1, 2016 . Other Intangible Assets A summary of amortizable intangible assets is as follows: As of July 1, 2016 (in millions) Gross Carrying Value Accumulated Amortization Net Carrying Value Software $ 2,414 $ 1,560 $ 854 Outsourcing contract costs 834 503 331 Customer and other intangible assets 928 217 711 Total intangible assets $ 4,176 $ 2,280 $ 1,896 As of April 1, 2016 (in millions) Gross Carrying Value Accumulated Amortization Net Carrying Value Software $ 2,243 $ 1,531 $ 712 Outsourcing contract costs 828 494 334 Customer and other intangible assets 485 203 282 Total intangible assets $ 3,556 $ 2,228 $ 1,328 Total intangible assets amortization was $80 million and $71 million for the three months ended July 1, 2016 and July 3, 2015 , respectively. These estimates included reductions of revenue for amortization of outsourcing contract cost premiums of $3 million and $3 million , respectively. Amortization expense related to capitalized software, included within total intangible amortization, was $43 million and $41 million for the three months ended July 1, 2016 and July 3, 2015 , respectively. Estimated future amortization expense related to intangible assets as of July 1, 2016 is as follows: Fiscal year (in millions) Remainder of 2017 $ 285 2018 $ 315 2019 $ 287 2020 $ 245 2021 $ 196 During the three months ended July 3, 2015 , CSC sold certain fully amortized intangible assets to a third party and recorded a $31 million gain on sale as a reduction of cost of sales in its GIS segment.

(2) Drawings under the lease credit facility convert into individual term notes of variable terms up to sixty months , depending on the nature of the underlying equipment being financed. Borrowings under the lease credit facility are classified as short-term debt if the Company intends to repay within 12 months and as long-term debt otherwise. During the first three months of fiscal 2017 , the Company amended its existing $2.5 billion credit facility by expanding its borrowing capacity to $2.9 billion , which was further expanded to $3.0 billion subsequent to July 1, 2016 (see Note 20 Subsequent Events). Additionally, the Company drew down $920 million on the credit facility and repaid $199 million . During the first three months of fiscal 2017 , the loan payable due May 2016 was replaced with borrowings under the credit facility. During the first three months of fiscal 2017 , the Company increased the maximum size of its existing European commercial paper program (the ECP Program) from €500 million to €1 billion or its equivalent in alternative currencies. The Company had borrowings of $511 million and repayments of $511 million under the ECP Program during the first three months of fiscal 2017 . Additionally, during the three months ended July 1, 2016 , the Company amended its existing master loan and security agreement which reduced the aggregate commitment under our lease credit facility from $250 million to $150 million . The drawdown availability period of the lease credit facility expires November 29, 2016 and, once drawn, converts into individual term notes of varying terms not to exceed 60 months, depending upon the nature of the underlying equipment being financed. The Company was in compliance with all financial covenants associated with its borrowings as of July 1, 2016 .

Compensation and Retirement Disclosure [Abstract]
Pension and Other Benefit Plans	Pension and Other Benefit Plans The Company sponsors a number of defined benefit plans and defined contribution plans for the benefit of eligible employees. The defined benefit plans comprise primarily pension plans and post-retirement medical benefit plans. The defined contribution plans include the Company's deferred compensation plan for executives and non-employee directors. Subsequent to the Separation, U.S. pension and other U.S. benefit plans represent an insignificant portion of the Company's pension and other post-retirement benefits. As a result, the disclosures below include the Company's U.S. and non-U.S. pension plans on a global consolidated basis. The net periodic pension benefit included the following components: Three months ended (in millions) July 1, 2016 July 3, 2015 Service cost $ 6 $ 6 Interest cost 21 23 Expected return on assets (43 ) (45 ) Amortization of prior service costs (5 ) (4 ) Net periodic pension benefit $ (21 ) $ (20 ) The weighted-average rates used to determine net periodic pension cost were as follows: Three months ended July 1, 2016 July 3, 2015 Discount or settlement rates 3.1 % 3.0 % Expected long-term rates of return on assets 6.3 % 6.3 % Rates of increase in compensation levels 2.6 % 2.8 % The Company contributed $3 million to the defined benefit pension plans and other post-retirement benefit plans during the first three months of fiscal 2017 . The Company expects to contribute an additional $66 million during the remainder of fiscal 2017 . Subsequent to the Separation, CSC had no assets in its other post-retirement benefit plans. The weighted-averages of the assumptions used to determine net periodic post-retirement income were as follows: Three months ended July 1, 2016 July 3, 2015 Discount or settlement rates 4.1 % 3.8 % Rates of increase in compensation levels 3.0 % 3.0 %

Income Taxes [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate (ETR) from continuing operations was 44.4% and 9.7% for the first three months of fiscal 2017 and 2016 , respectively. For the first three months of fiscal 2017 , the primary drivers of the ETR increase was the global mix of income, and excess tax benefits related to employee share-based payment awards, reduced by non-deductible transaction related costs. The primary driver of the ETR for the first three months of fiscal year 2016 was the global mix of income and the impact of ASU 2016-09. There were no material changes to uncertain tax positions in the first quarter of fiscal 2017 compared to the fiscal 2016 year-end. It is reasonably possible that during the next 12 months the Company's liability for uncertain tax positions may change by a significant amount. The IRS is examining the Company's federal income tax returns for fiscal 2008 through 2013. The Company entered into negotiations for a resolution of the fiscal 2008 through 2010 audit through settlement with the IRS Office of Appeals. The IRS examined several issues for this audit that resulted in various audit adjustments. The Company has agreed to extend the statute of limitations associated with the audit through March 31, 2017. During the fourth quarter of fiscal 2016, the Company and the IRS reached an agreement in principle as to the settlement terms and the Company remeasured its uncertain tax positions. In addition, the Company may settle certain other tax examinations, have lapses in statute limitations, or voluntarily settle income tax positions in negotiated settlements for different amounts than the Company has accrued as uncertain tax positions. The Company may need to accrue and ultimately pay additional amounts for tax positions that previously met a more likely than not standard if such positions are not upheld. Conversely, the Company could settle positions with the tax authorities for amounts lower than those that have been accrued or extinguish a position though payment. The Company believes the outcomes which are reasonably possible within the next 12 months may result in a reduction in liability for uncertain tax positions of between $18 million and $49 million , excluding interest, penalties, and tax carryforwards.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Incentive Plans	Stock Incentive Plans The Company recognized stock-based compensation expense (benefit) as follows: Three months ended (in millions) July 1, 2016 July 3, 2015 Cost of services $ 6 $ (11 ) Selling, general and administrative 8 (1 ) Total $ 14 $ (12 ) Total, net of tax $ 9 $ (8 ) Stock-based compensation for the first three months of fiscal 2016 was a benefit due to changes in the assumed forfeiture rates in fiscal 2015 . The Company uses the Black-Scholes-Merton model in determining the fair value of stock options granted. The weighted average grant-date fair values of stock options granted during the three months ended July 1, 2016 and July 3, 2015 were $12.40 and $20.10 per share, respectively. In calculating the compensation expense for its stock incentive plans, the Company used the following weighted-average assumptions: Three months ended July 1, 2016 July 3, 2015 Risk-free interest rate 1.56 % 1.80 % Expected volatility 29 % 32 % Expected term (in years) 6.19 6.22 Dividend yield 1.67 % 1.39 % As a result of the Separation, most stock awards issued by the Company were modified, including acceleration of vesting of certain awards and the issuance of new CSRA awards under the basket method, whereby awards granted prior to fiscal year 2016 in CSC equity were converted into two awards: an adjusted CSC equity award and a CSRA equity award. In the case of stock options, the number of options and the exercise price were adjusted for the impact of the Separation. The conversions were structured to generally preserve the intrinsic value of the awards immediately prior to the Separation. There was no incremental stock compensation expense recognized as a result of the modification of the awards. Employee Incentives The Company currently has two active stock incentive plans that authorize the issuance of stock options, restricted stock and other stock-based incentives to employees upon terms approved by the Compensation Committee of the Board of Directors. The Company issues authorized but previously unissued shares upon the exercise of stock options, the granting of restricted stock and the settlement of RSUs. As of July 1, 2016 , 6,817,452 shares of CSC common stock were available for the grant of future stock options, equity awards or other stock-based incentives to employees under such stock incentive plans. Stock Options The Company’s standard vesting schedule for stock options is one-third of the total stock option award on each of the first three anniversaries of the grant date. Stock options are generally exercisable for a term of ten years from the grant date. Information concerning stock options granted under the Company's stock incentive plans is as follows: Number of Option Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value (millions) Outstanding as of April 1, 2016 (1) 5,366,621 $ 24.83 7.06 $ 51 Granted 2,055,958 49.25 Exercised (1,716,447 ) 21.34 44 Canceled/Forfeited (187,097 ) 29.84 Expired (44,322 ) 23.19 Outstanding as of July 1, 2016 5,474,713 34.94 8.25 79 Vested and expected to vest in the future as of July 1, 2016 5,346,408 35.04 8.23 77 Exercisable as of July 1, 2016 2,041,272 $ 23.65 6.21 $ 53 (1) The amount of the weighted average exercise price and aggregate intrinsic value has been revised to reflect the impact of the Separation.

The cash received from stock options exercised during the three months ended July 1, 2016 and July 3, 2015 was $36 million and $24 million , respectively. As of July 1, 2016 , there was $34 million of total unrecognized compensation expense related to unvested stock options, net of expected forfeitures.

Segment Information [Abstract]
Segment Information	Segment Information Due to the Separation, on November 27, 2015, North American Public Sector is no longer included as a reportable segment and its results have been reclassified to discontinued operations, net of taxes, for the three months ended July 3, 2015 . CSC now operates in two reportable segments, as follows: • Global Business Services - GBS provides innovative technology solutions including consulting, applications services and software, which address key business challenges within the customer’s industry. GBS strives to help clients understand and exploit industry trends of IT modernization and virtualization of the IT portfolio (hardware, software, networking, storage and computing assets). GBS has four primary focus areas: industry aligned next-generation software and solutions, end-to-end applications services, consulting services, and big data services. Industry aligned next-generation software and solutions is centered on the insurance, banking, healthcare and life sciences industries, as well as manufacturing and other diversified industries. Activities are primarily related to vertical alignment of software solutions and process-based intellectual property that power mission-critical transaction engines, in addition to the provision of tailored business process services (BPS). Applications services optimize and modernize clients' business and technical environments, enabling clients to capitalize on emerging services such as cloud and mobility as well as big data within new commercial models including "as a Service." The consulting services business helps organizations innovate, transform and create sustainable competitive advantage through a combination of industry, business process, technology, systems integration and change management expertise. Key competitive differentiators for GBS include its global scale, solution objectivity, depth of industry expertise, strong partnerships, vendor and product independence and end-to-end solutions and capabilities. Changing business issues such as globalization, fast-developing economies, government regulation and growing concerns around risk, security and compliance drive demand for these GBS offerings. • Global Infrastructure Services – GIS provides managed and virtual desktop solutions, unified communications and collaboration services, data center management, cyber security, compute and managed storage solutions to commercial clients globally. GIS also delivers CSC's next-generation cloud offerings, including Infrastructure as a Service (IaaS), private cloud solutions and Storage as a Service. GIS provides a portfolio of standard offerings that have predictable outcomes and measurable results while reducing business risk and operational costs for clients. To provide clients with differentiated offerings, GIS maintains a select number of key alliance partners to make investments in developing unique offerings and go-to-market strategies. This collaboration helps CSC determine the best technology, develop road maps and enhance opportunities to differentiate solutions, expand market reach, augment capabilities and jointly deliver impactful solutions. The following table summarizes operating results by reportable segment: (in millions) GBS GIS Corporate Total Three months ended July 1, 2016 Revenues $ 1,049 $ 881 $ — $ 1,930 Operating income (loss) (1) $ 73 $ (4 ) $ (17 ) $ 52 Depreciation and amortization $ 36 $ 114 $ 16 $ 166 Three months ended July 3, 2015 Revenues $ 919 $ 885 $ — $ 1,804 Operating income (loss) (1) $ 97 $ 53 $ (6 ) $ 144 Depreciation and amortization $ 30 $ 135 $ 9 $ 174 (1) Operating income (loss) is a non-GAAP financial measure which management believes assists investors in comparing the Company's performance across reporting periods on a consistent basis by excluding items that management does not believe are indicative of the Company's core operating performance, and are considered important measures by financial analysts covering CSC and its peers. Operating income (loss) provides useful information to the Company’s management for assessment of the Company’s performance and results of operations and is one of the financial measures utilized to determine executive compensation.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidated Variable Interest Entities	Consolidated Variable Interest Entities On November 2, 2015, CSC entered into a partnership with HCL Technologies Ltd. (HCL) structured as two private limited companies, incorporated in the United Kingdom: CeleritiFinTech Limited and CeleritiFinTech Services Limited. The subsidiaries were formed to operate and further invest in and expand banking products with the combined objective to promote and generate revenues from banking and other customers. CSC holds a 49% membership interest in CeleritiFinTech Limited and a 51% membership interest in CeleritiFinTech Services Limited. During the three months ended July 1, 2016 , results of operations conducted within these entities were not material to the Company's unaudited Condensed Consolidated Statements of Operations. As of July 1, 2016 , no assets were pledged by the Company as collateral and there was no additional exposure to the Company for loss due to its involvement with these entities. The assets and liabilities attributable to these entities were not material to the Company's unaudited Condensed Consolidated Balance Sheets. The Company determined that it is the primary beneficiary of these entities and, as such, follows accounting treatment for variable interest entities that properly meet the criteria for consolidation.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments The Company signed long-term purchase agreements with certain software, hardware, telecommunication and other service providers to obtain favorable pricing and terms for services and products that are necessary for the operations of business activities. Under the terms of these agreements, the Company is contractually committed to purchase specified minimums over periods ranging from one to seven years . If the specified minimums are not met, the Company would have an obligation to pay the service provider all or a portion of the shortfall. Minimum purchase commitments as of July 1, 2016 were $317 million for fiscal 2017 , $343 million for fiscal 2018 and $1.2 billion for fiscal 2019 and thereafter. In the normal course of business, the Company may provide certain clients with financial performance guarantees, which are generally backed by letters of credit or surety bonds. In general, CSC would only be liable for the amounts of these guarantees in the event that its nonperformance permits termination of the related contract by the Company’s client. The Company believes it is in compliance with its performance obligations under all service contracts for which there is a financial performance guarantee and the ultimate liability, if any, incurred in connection with these guarantees will not have a material adverse effect on its consolidated results of operations or financial position. The Company also uses stand-by letters of credit, in lieu of cash, to support various risk management insurance policies. These letters of credit represent a contingent liability and the Company would only be liable if it defaults on its payment obligations towards these policies. Generally, such guarantees have a one -year term and are renewed annually. The following table summarizes the expiration of the Company’s financial guarantees and stand-by letters of credit outstanding as of July 1, 2016 : (in millions) Fiscal 2017 Fiscal 2018 Fiscal 2019 and thereafter Total Surety bonds $ 21 $ — $ — $ 21 Letters of credit 12 2 32 46 Stand-by letters of credit 43 — 17 60 Total $ 76 $ 2 $ 49 $ 127 The Company generally indemnifies licensees of its proprietary software products against claims brought by third parties alleging infringement of their intellectual property rights (including rights in patents, with or without geographic limitations), copyrights, trademarks and trade secrets). CSC’s indemnification of its licensees relates to costs arising from court awards, negotiated settlements and the related legal and internal costs of those licensees. The Company maintains the right, at its own costs, to modify or replace software in order to eliminate any infringement. Historically, CSC has not incurred any significant costs related to licensee software indemnification. Contingencies Unless otherwise noted, the Company is unable to develop a reasonable estimate of a possible loss or range of losses associated with the following contingent matters at this time. Vincent Forcier v. Computer Sciences Corporation and The City of New York On October 27, 2014, the United States District Court for the Southern District of New York unsealed a qui tam complaint that had been filed under seal over two years prior in a case entitled United States of America and State of New York ex rel. Vincent Forcier v. Computer Sciences Corporation and The City of New York, Case No. 1:12-cv-01750-DAB. The original complaint was brought by Vincent Forcier, a former employee of Computer Sciences Corporation, as a private party qui tam relator on behalf of the United States and the State of New York. The relator’s amended complaint, dated November 15, 2012, which remained under seal until October 27, 2014, alleged civil violations of the federal False Claims Act, 31 U.S.C. § 3729 et seq., and New York State’s False Claims Act, NY. Finance L, Art. 13, § 187 et seq., arising out of certain coding methods employed with respect to claims submitted by the Company to Medicaid for reimbursements as fiscal agent on behalf of its client, New York City’s Early Intervention Program (EIP). EIP is a federal program promulgated by the Individuals with Disabilities in Education Act, 20 U.S.C. § 1401 et seq. (IDEA), that provides early intervention services for infants and toddlers who have, or are likely to have, developmental delays. Prior to the unsealing of the complaint on October 27, 2014, the United States Attorney’s Office for the Southern District of New York investigated the allegations in the qui tam relator’s complaint. That investigation included requests for information to the Company concerning the Company’s databases, software programs and related documents regarding EIP claims submitted by the Company on behalf of New York City. The Company produced documents and information that the government requested and cooperated fully with the government’s investigation regarding this matter at all times. In addition, the Company conducted its own investigation of the matter and openly shared its findings and worked constructively with all parties to resolve the matter. At the conclusion of its investigation, the Company concluded that it had not violated the law in any respect. On October 27, 2014, the United States Attorney’s Office for the Southern District of New York and the Attorney General for the State of New York filed complaints-in-intervention on behalf of the United States and the State of New York, respectively. The complaints allege that, from 2008 to 2012, the Company and New York City used the automatic defaulting capabilities of a computerized billing system that the Company developed for New York City’s EIP in order to orchestrate a billing fraud against Medicaid and failed to comply with Medicaid requirements regarding submission of claims to private insurance. The New York Attorney General’s complaint also alleges that the Company failed to reimburse Medicaid in certain instances where insurance had paid a portion of the claim. The lawsuits seek damages under the federal False Claims Act, the New York False Claims Act and common law theories in an amount equal to three times the sum of an unspecified amount of damages the United States and New York State allegedly sustained, plus civil penalties together with attorneys’ fees and costs. On January 26, 2015, the Company and the City of New York filed motions to dismiss Forcier’s amended complaint and the federal and state complaints-in-intervention. On April 28, 2016, the Court issued a decision on the motions. The Court dismissed Forcier’s amended complaint, some claims related to allegations of fraudulent defaulting practices and the claims related to the alleged failure to reimburse Medicaid. The Court denied the motions to dismiss claims based on other allegations of fraudulent defaulting practices and the alleged noncompliance with Medicaid requirements to bill private insurance, as well as the claims seeking damages under the common law. The Company believes that the remaining allegations are without merit and intends to vigorously defend itself. The United States and the State of New York have advised the Court that they are considering filing a further amended complaint. Their deadline to do so is August 24, 2016. Defendants’ deadline to answer, or move to dismiss, that amended complaint (if filed) is October 14, 2016. CSC v. Eric Pulier On May 12, 2015, the Company and its wholly owned subsidiary, ServiceMesh Inc. (SMI), filed a civil complaint in the Court of Chancery of the State of Delaware against Eric Pulier (C.A. No. 11011-VCP). The Company acquired SMI on November 15, 2013. The purchase consideration included a cash payment at closing, as well as additional contingent consideration based on a contractually defined multiple of SMI’s revenues during a specified period ending January 31, 2014 (the Earnout Payment), all as set forth in the purchase agreement governing the acquisition. Before the acquisition, Mr. Pulier was the chief executive officer, chairman and one of the largest equity holders of SMI. Following the acquisition, Mr. Pulier became employed by the Company, at which time he executed a retention agreement pursuant to which he received a grant of restricted stock units of the Company and agreed to be bound by the Company’s rules and policies, including the Company’s Code of Business Conduct. In March 2015, the Company became aware of, and began its own investigation into the circumstances surrounding, the arrests of two former employees of the Commonwealth Bank of Australia Ltd. (CBA) in connection with payments allegedly received by them, either directly or indirectly, from Mr. Pulier. SMI and CBA had entered into several contracts with each other, including contracts that contributed to the Earnout Payment. In April 2015, the Company was contacted by the Australian Federal Police regarding the alleged payments. The Company is cooperating with and assisting the Australian and U.S. authorities in their investigations of the conduct of various individuals involved in SMI transactions during the earnout period. The Company’s and SMI’s original complaint against Mr. Pulier asserted claims for (i) breach of the purchase agreement, (ii) breach of the implied covenant of good faith and fair dealing in the purchase agreement, (iii) fraud, (iv) fraud by omission, (v) breach of his retention agreement, (vi) breach of the implied covenant of good faith and fair dealing in his retention agreement and (vii) breach of fiduciary duty. Mr. Pulier filed a motion to dismiss the complaint on May 28, 2015 and an opening brief in support of such motion on July 7, 2015. The Company and SMI filed a First Amended Complaint on August 6, 2015, adding as defendants TechAdvisors, LLC (TechAdvisors), an entity controlled by Mr. Pulier and Shareholder Representative Services LLC (SRS). In addition to the claims asserted against Mr. Pulier, the First Amended Complaint asserted claims against TechAdvisors for (i) breach of the purchase agreement, (ii) breach of the implied covenant of good faith and fair dealing in the purchase agreement and (iii) fraud. The amended complaint added claims against SRS in its capacity as attorney-in-fact and representative of Mr. Pulier and TechAdvisors for breach of their indemnification obligations in the purchase agreement. Mr. Pulier, SRS and TechAdvisors filed motions to dismiss the First Amended Complaint on August 20, August 31 and September 8, 2015 respectively. On October 7, 2015, the Company filed its Second Amended Complaint against Mr. Pulier, TechAdvisors and SRS. In addition to the claims asserted against Mr. Pulier, TechAdvisors and SRS in the First Amended Complaint, the Second Amended Complaint asserts claims against SRS in its capacity as attorney-in-fact and representative of the former equityholders of ServiceMesh who are not current employees of CSC for breach of their indemnification obligations in the purchase agreement. The Second Amended Complaint seeks recovery of payments made to Mr. Pulier and TechAdvisors under the purchase agreement, the value of Mr. Pulier’s vested restricted stock units of the Company granted to him under his retention agreement and the full amount of the Earnout Payment, which was approximately $98 million . Defendants filed motions to dismiss the Second Amended Complaint on November 6, 2015. On December 17, 2015, the Company entered into a settlement agreement with the majority of the former equityholders of ServiceMesh, as well as SRS acting in its capacity as the agent and attorney-in-fact for the settling equityholders. Pursuant to the settlement agreement, the Company received $16.5 million , which amount was equal to the settling equityholders’ pro rata share of the funds remaining in escrow from the transaction, which was recorded as an offset to selling, general and administrative costs in our Consolidated Statements of Operations for the fiscal year ended April 1, 2016 . The Company also moved to dismiss its claims against the settling equityholders and SRS, in its representative capacity for those equityholders. The Court granted the motion to dismiss on January 11, 2016. On April 29, 2016, the Court orally ruled on Defendants’ motions to dismiss the Second Amended Complaint. It entered an Order granting the same relief on May 9, 2016. The Court largely denied Defendants’ motions and will allow the majority of the Company’s claims against Mr. Pulier, TechAdvisors and SRS to proceed. The Court dismissed the Company’s claim against Mr. Pulier for breach of the implied covenant of good faith and fair dealing in his retention agreement, one alternative factual basis for the Company’s claims for breach of the purchase agreement and fraud and another alternative factual basis for the Company’s claim against Mr. Pulier for fraud. On May 23, 2016, SRS filed its Answer to the Second Amended Complaint. On June 3, 2016, Mr. Pulier and TechAdvisors filed an Answer and Mr. Pulier filed a Counterclaim against the Company. Mr. Pulier asserts counter-claims for (i) breach of the purchase agreement, (ii) breach of the implied covenant of good faith and fair dealing in the purchase agreement, (iii) fraud, (iv) negligent representation, (v) rescission of the purchase agreement and (vi) breach of his retention agreement. On June 23, 2016, the Company filed a motion to dismiss Mr. Pulier’s counterclaims, and the Company filed its opening brief in support of its motion to dismiss on July 29, 2016. The parties are negotiating the remaining schedule for the briefing of that motion. Additionally, on February 17, 2016, Mr. Pulier filed a complaint against the Company and its subsidiary-CSC Agility Platform, Inc., formerly known as SMI-seeking advancement of his legal fees and costs in the case described above. The summary proceeding is in the Court of Chancery of the State of Delaware (C.A. No. 12005-CB). On May 12, 2016, the Court ruled that the Company is not liable to advance legal fees to Mr. Pulier because he was not an officer or director of the Company, but that its subsidiary-as the successor to SMI-is liable for advancing 80% of Mr. Pulier’s fees in the underlying action. The Court entered an Order granting the same relief on May 27, 2016. On July 7, 2016, Mr. Pulier requested advancement from CSC Agility Platform, Inc., as the successor to SMI, for his attorneys’ fees and expenses incurred in connection with criminal and regulatory investigations and prosecutions. CSC Agility Platform is investigating and analyzing that demand. Strauch et al. Fair Labor Standards Act Class Action On July 1, 2014, plaintiffs filed Strauch and Colby v. Computer Sciences Corporation in the U.S. District Court for the District of Connecticut, a putative nationwide class action alleging that CSC violated provisions of the Fair Labor Standards Act (FLSA) with respect to system administrators who worked for CSC at any time from June 1, 2011 to the present. Plaintiffs claim that CSC improperly classified its system administrators as exempt from the FLSA and that CSC therefore owes them overtime wages and associated relief available under the FLSA and various statutes, including the Connecticut Minimum Wage Act, the California Unfair Competition Law, California Labor Code, California Wage Order No. 4-2001 and the California Private Attorneys General Act. The relief sought by plaintiffs includes unpaid overtime compensation, liquidated damages, pre- and post-judgment interest, damages in the amount of twice the unpaid overtime wages due and civil penalties. CSC’s position is that its system administrators have the job duties, responsibilities and salaries of exempt employees and are properly classified as exempt from overtime compensation requirements. CSC’s Motion to Transfer Venue was denied in February 2015. On June 9, 2015, the Court entered an order granting the plaintiffs’ motion for conditional certification of the class of system administrators. The Strauch putative class includes more than 4,000 system administrators. Courts typically undertake a two-stage review in determining whether a suit may proceed as a class action under the FLSA. In its order, the Court noted that, as a first step, the Court examines pleadings and affidavits, and if it finds that proposed class members are similarly situated, the class is conditionally certified. Potential class members are then notified and given an opportunity to opt-in to the action. The second step of the class certification analysis occurs upon completion of discovery. At that point, the Court will examine all evidence then in the record to determine whether there is a sufficient basis to conclude that the proposed class members are similarly situated. If it is determined that they are, the case will proceed to trial; if it is determined they are not, the class is decertified and only the individual claims of the purported class representatives proceed. The Company’s position in this litigation continues to be that the employees identified as belonging to the conditional class were paid in accordance with the FLSA. Plaintiffs filed an amended complaint to add additional plaintiffs and allege violations under Missouri and North Carolina wage and hour laws. We do not believe these additional claims differ materially from those in the original complaint. On June 3, 2016, Plaintiffs filed a motion for Rule 23 class certification of California, Connecticut and North Carolina state-law classes and the Company filed its opposition to the motion on July 15, 2016. In addition to the matters noted above, the Company is currently party to a number of disputes which involve or may involve litigation. The Company accrues a liability when management believes that it is both probable that a liability has been incurred and the amount of loss can be reasonably estimated under ASC 450 "Contingencies." The Company believes it has appropriately recognized liabilities for any such matters. Regarding other matters that may involve actual or threatened disputes or litigation, the Company, in accordance with the applicable reporting requirements, provides disclosure of such matters for which the likelihood of material loss is at least reasonably possible. The Company assessed reasonably possible losses for all other such pending legal or other proceedings in the aggregate and concluded that the range of potential loss is not material. The Company also considered the requirements regarding estimates used in the disclosure of contingencies under ASC 275 "Risks and Uncertainties." Based on that guidance, the Company determined that supplemental accrual and disclosure was not required for a change in estimate that involves contingencies because the Company determined that it was not reasonably possible that a change in estimate will occur in the near term. The Company reviews contingencies during each interim period and adjusts its accruals to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular matter.

Reconciliation of Previously Reported Amounts	Reconciliation of Previously Reported Amounts During fiscal 2016 , the Company identified certain errors in previously issued financial statements related to income taxes. These errors resulted in adjustments to the unaudited Condensed Consolidated Financial Statements for the three months ended July 3, 2015. The Company considered the guidance in ASC 250-10-S99-2 “Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in the Current Year Financial Statements” in evaluating the effects of these misstatements on the Company's previously issued financial statements and concluded that the previously issued financial statements were not materially misstated. To correct these misstatements, the Company decreased income from continuing operations by $11 million for the three months ended July 3, 2015 . As described in Note 1 Basis of Presentation the Company adopted ASU 2016-09 in the fourth quarter of fiscal 2016 which requires us to reflect any adjustments as of April 4, 2015, the beginning of the annual period that includes the adoption. As described in Note 4 Divestitures , during fiscal 2016 , the Company completed the Separation and reclassified certain financial statement line items to discontinued operations. A reconciliation of the amounts previously reported on Form 10-Q for the first three months of fiscal 2016 to those as adjusted within the accompanying unaudited Condensed Consolidated Statements of Operations is shown in the table below for selected financial amounts: (in millions) Three Months Ended July 3, 2015 Condensed Consolidated Statement of Operations (unaudited) As Previously Reported Reclassification of Discontinued Operations Correction of Prior Period Misstatement (1) Adoption of ASU 2016-09 As Adjusted Income (loss) from continuing operations, before taxes $ 228 $ (156 ) $ — $ — $ 72 Income tax (benefit) expense $ 64 $ (54 ) $ 11 $ (14 ) $ 7 Income (loss) from continuing operations $ 164 $ (102 ) $ (11 ) $ 14 $ 65 Income from discontinued operations $ — $ 102 $ — $ — $ 102 Net income (loss) $ 164 $ — $ (11 ) $ 14 $ 167 Net income (loss) attributable to CSC common stockholders $ 160 $ — $ (11 ) $ 14 $ 163 (1) Reflects the correction of misstatements identified related to previously issued financial statements as described in Note 1 Basis of Presentation .

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On July 5, 2016, the Company completed the previously announced acquisition of Aspediens. Aspediens is a provider of technology-enabled solutions for the service-management sector and a preferred partner of ServiceNow. With headquarters in Switzerland, Aspediens has operations in Germany, France and Spain. Aspediens will join the CSC ServiceNow practice within Fruition Partners, a CSC company and ServiceNow platform that also includes UXC Keystone, Australia’s ServiceNow practice within UXC, a CSC company. On July 25, 2016, CSC exercised an option under its revolving credit agreement to incur incremental commitments in an aggregate amount of $100 million . The incurrence of the incremental commitments resulted in an increase in the aggregate outstanding facility size from $2.9 billion to $3.0 billion , of which $2.8 billion matures on January 15, 2021 and $150 million matures on January 15, 2020. In addition, the Company entered into conditional revolver commitments totaling $740 million that are contingent on the closing of its announced merger with the Enterprise Services segment of HPE which will further expand CSC's borrowing capacity to $3.7 billion , if the Company accepts such commitments. On July 25, 2016, the Company, through its CSC Australia PTY Limited (CSCA) subsidiary, entered into a $100 million AUD term loan credit facility maturing July 2021. The AUD term loan agreement permits the Company to request incremental term loans of up to $175 million AUD, which, if requested by the Company and agreed to by the lenders, would result in a maximum of $275 million AUD in total term facilities.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Basis of presentation	Computer Sciences Corporation (CSC or the Company) has prepared the interim unaudited Condensed Consolidated Financial Statements included herein pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for quarterly reports and, therefore, omit or condense certain note disclosures and other information required by generally accepted accounting principles in the United States (GAAP) for complete financial statements. These financial statements should therefore be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company's Annual Report on Form 10-K for the fiscal year ended April 1, 2016 (fiscal 2016 ). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts and disclosures reported in the financial statements and accompanying notes. As a result, actual results may be different from these estimates. In the opinion of the Company's management, the accompanying unaudited Condensed Consolidated Financial Statements of CSC contain all adjustments necessary, including those of a normal recurring nature, to present fairly the Company's financial position as of July 1, 2016 and April 1, 2016 and its results of operations and cash flows for the three months ended July 1, 2016 and July 3, 2015 . The results of operations for such interim periods are not necessarily indicative of the results for the full year ending March 31, 2017 . Certain prior year amounts have been reclassified to conform to the current year presentation.
Fiscal period	The Company reports its results based on a fiscal year convention that comprises four thirteen-week quarters. Every fifth year includes an additional week in the first quarter to prevent the fiscal year from moving from an approximate end of March date.
New Accounting Standards and Standards Issued But Not Yet Effective	New Accounting Standards During the first three months of fiscal 2017 , the Company adopted the following Accounting Standard Updates (ASUs): ASU 2015-16, Business Combinations (Topic 805), "Simplifying the Accounting for Measurement Period Adjustments" requires an acquirer in a business combination to account for a measurement-period adjustment during the period in which the amount is determined, instead of retrospectively. CSC adopted this ASU effective April 2, 2016 and has not had any measurement-period adjustments since adoption. As a result, there has been no impact to CSC's financial statements. ASU 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs" as clarified by ASU 2015-15, "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements—Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting" (ASU 2015-15) states that debt issuance costs are presented in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Presentation of fees under line of credit (LOC) arrangements had not been specified in this ASU; as a result, ASU 2015-15 was issued. ASU 2015-15 states that the SEC staff would not object to an entity deferring LOC commitment fees as an asset and subsequently amortizing ratably over the term of the underlying LOC arrangement, regardless of whether there are outstanding borrowings under that LOC arrangement. CSC adopted both ASUs effective April 2, 2016 and the impact upon the unaudited Condensed Consolidated Financial Statements was immaterial. ASU 2015-05, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement" issued guidance about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement does not contain a software license, the customer should account for the arrangement as a service contract. If the arrangement includes software licenses, it should be accounted for consistent with other licenses of intangible assets. CSC elected to adopt this ASU prospectively effective April 2, 2016. Adoption of this ASU did not have a material impact on the unaudited Condensed Consolidated Financial Statements. Standards Issued But Not Yet Effective The following ASUs were recently issued but have not yet been adopted by CSC: In June 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): "Measurement of Credit Losses on Financial Instruments", which is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this update replace the existing incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 will be effective for CSC in fiscal 2020. This ASU must be adopted using a prospective transition approach for debt securities for which an other-than-temporary impairment had been recognized before the effective date. CSC is currently evaluating the impact of the adoption of ASU 2016-13 may have on its unaudited Condensed Consolidated Financial Statements in future reporting periods. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)". This amendment is intended to increase transparency and comparability among organizations by recognizing virtually all lease assets and lease liabilities on the balance sheet and disclosing key information about lease arrangements. ASU 2016-02 will be effective for CSC in fiscal 2020 and early adoption is permitted. This ASU must be adopted using a modified retrospective transition and provides for certain practical expedients. CSC is currently evaluating the impact that the adoption of ASU 2016-02 may have on its unaudited Condensed Consolidated Financial Statements in future reporting periods. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities", which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 will be effective for CSC in fiscal 2019. This ASU should be applied prospectively to equity investments that exist as of the date of adoption for equity securities without readily determinable fair values. CSC is currently evaluating the impact of the adoption of ASU 2016-01 may have on CSC's unaudited Condensed Consolidated Financial Statements in future reporting periods. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (ASU 2014-09). ASU 2014-09 supersedes the revenue recognition requirements in ASC Topic 605, “Revenue Recognition” and some cost guidance included in ASC Subtopic 605-35, "Revenue Recognition - Construction-Type and Production-Type Contracts.” The core principle of ASU 2014-09 is that revenue is recognized when the transfer of goods or services to customers occurs in an amount that reflects the consideration to which CSC expects to be entitled in exchange for those goods or services. ASU 2014-09 requires the disclosure of sufficient information to enable readers of CSC’s financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09 also requires disclosure of information regarding significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 provides two methods of retrospective application. The first method would require CSC to apply ASU 2014-09 to each prior reporting period presented. The second method would require CSC to retrospectively apply ASU 2014-09 with the cumulative effect recognized at the date of initial application. ASU 2014-09 will be effective for CSC beginning in fiscal 2019 as a result of ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date" (ASU 2015-14) which was issued by the FASB in August 2015 and extended the original effective date by one year. CSC is currently evaluating the impact of adopting the available methodologies of ASU 2014-09 and 2015-14 upon its unaudited Condensed Consolidated Financial Statements in future reporting periods. There have been three new ASUs issued amending certain aspects of ASU 2014-09. ASU 2016-08 "Principal versus Agent Considerations (Reporting Revenue Gross Versus Net)," was issued in March, 2016 to clarify certain aspects of the principal versus agent guidance in ASU 2014-09. In addition, ASU 2016-10 "Identifying Performance Obligations and Licensing" issued in April 2016, amends other sections of ASU 2014-09 including clarifying guidance related to identifying performance obligations and licensing implementation. Finally, ASU 2016-12, "Revenue from Contracts with Customers - Narrow Scope Improvements and Practical Expedients" provides amendments and practical expedients to the guidance in ASU 2014-09 in the areas of assessing collectability, presentation of sales taxes received from customers, noncash consideration, contract modification and clarification of using the full retrospective approach to adopt ASU 2014-09. With its evaluation of the impact of ASU 2014-09, CSC will also consider the impact related to the updated guidance provided by these three new ASUs. Other recently issued ASUs effective after July 1, 2016 are not expected to have a material effect on CSC's unaudited Condensed Consolidated Financial Statements in future reporting periods.

As a result, weighted average diluted shares outstanding has been adjusted from the amount previously reported for the three months ended July 3, 2015 to exclude excess tax benefits from the assumed proceeds in the diluted shares calculation. The adoption of this standard resulted in diluted weighted average shares outstanding of 141.39 million for the three months ended July 3, 2015 versus 140.80 million as calculated under the previous guidance. Stock options and RSUs with an exercise price greater than the average market price of the shares for the full year would have been anti-dilutive, and therefore were excluded from the diluted earnings per share computation.
