								Basis of Presentation and Principles of Consolidation
	Computer Sciences Corporation (CSC or the Company) has prepared the interim period unaudited Consolidated Condensed Financial Statements included herein, as of and for the quarters ended June 28, 2013 and June 29, 2012, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (GAAP) have been condensed or omitted pursuant to such rules and regulations. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Condensed Financial Statements and the accompanying notes. It is recommended that these Consolidated Condensed Financial Statements be read in conjunction with the financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended March 29, 2013 (fiscal 2013). In the opinion of management, the unaudited Consolidated Condensed Financial Statements included herein reflect all adjustments necessary, including those of a normal recurring nature, to present fairly the financial position, the results of operations and the cash flows for such interim periods. The results of operations for such interim periods are not necessarily indicative of the results for the full year ending March 28, 2014 (fiscal 2014).
								The accompanying consolidated financial statements and notes are those of Computer Sciences Corporation, its subsidiaries, and those business entities in which the Company maintains a controlling interest, hereafter collectively referred to as “CSC” or “the Company.” Investments in business entities in which the Company does not have control, but has the ability to exercise significant influence over operating and financial policies, are accounted for by the equity method. Other investments are accounted for by the cost method. All intercompany transactions and balances have been eliminated.
	With the beginning of fiscal 2014, the Company began operating under new reportable segments. The new reportable segments are North American Public Sector (NPS), Global Infrastructure Services (GIS) and Global Business Services (GBS) (see Note 13). All prior period segment disclosures have been recast to reflect the Company's change in reportable segments.
								The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC).
	The Consolidated Condensed Statements of Operations, of Comprehensive Income (Loss) and of Changes in Equity, along with the related notes, for the quarter ended June 29, 2012, have been recast from those presented in the previously filed Form 10-Q to reflect discontinued operations of the two businesses sold in fiscal 2014, the three businesses sold in fiscal 2013 (see Note 3), as well as the business that CSC has committed to a plan to sell (see Notes 3 and 18).
								Effective at the beginning of fiscal 2014, the Company began operating under new reportable segments. The new reportable segments are Global Business Services (GBS), Global Infrastructure Services (GIS) and North American Public Sector (NPS) (see Note 16). All prior period segment disclosures have been recast to reflect the Company's change in reportable segments.
	The Consolidated Condensed Balance Sheet for the year ended March 29, 2013 has not been recast to reflect the assets and liabilities divested as a result of the two fiscal 2014 discontinued operations. The Consolidated Condensed Statements of Cash Flows for the quarters ended June 28, 2013 and June 29, 2012 include both continuing and discontinued operations.
								The Consolidated Statements of Operations, Consolidated Statements of Comprehensive Income, and related notes, for the fiscal years ended March 29, 2013, March 30, 2012 and April 1, 2011, have been recast from those presented in the previously filed Form 10-K to reflect discontinued operations of the three businesses sold in fiscal 2014, as well as the business that CSC has committed to a plan to sell (see Notes 3 and 21).
	The Company's income from continuing operations, before taxes and noncontrolling interest, and diluted earnings per share (EPS) from continuing operations included the following adjustments due to changes in estimated profitability on fixed price contracts accounted for under the percentage-of-completion method for the quarters presented:
								The Consolidated Balance Sheets for the years ended March 29, 2013 and March 30, 2012 have not been recast to reflect the assets and liabilities divested as a result of sale of the two businesses. The Consolidated Statements of Cash Flows for all the fiscal years presented include both continuing and the discontinued operations.

	(Amounts in millions, except per-share data)	June 28, 2013			June 29, 2012			Use of Estimates
	Gross favorable	$	17		$	9
								GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. These estimates are based on management’s best knowledge of historical experience, current events, and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from these estimates. Amounts subject to significant judgment and estimates include, but are not limited to, contracts accounted for using the percentage-of-completion method, cash flows used in the evaluation of impairment of goodwill and other long-lived assets, intangible assets, certain deferred costs, collectability of receivables, reserves for uncertain tax benefits, valuation allowances on deferred tax assets, loss accruals for litigation, pension related liabilities, inputs used for computing stock-based compensation and the fair value of derivative instruments.

	Unbilled recoverable amounts under contracts in progress do not have an allowance for credit losses, and therefore, any adjustments to unbilled recoverable amounts under contracts in progress related to credit quality would be accounted for as a reduction of revenue. Unbilled recoverable amounts under contracts in progress resulting from sales, primarily to the United States (U.S.) and other governments, that are expected to be collected after one year totaled $44 million and $48 million as of June 28, 2013 and March 29, 2013, respectively.

								(2)	Quarterly changes in estimated profitability on the same fixed price contract are disclosed gross as either favorable or unfavorable.
								Revenue Recognition
								The Company's primary service offerings are information technology (IT) outsourcing, and both IT and other professional services. Revenues are recognized when persuasive evidence of an arrangement exists, services or products have been provided to the client, the sales price is fixed or determinable, and collectability is reasonably assured. For non-software arrangements that include multiple-elements, revenue recognition involves the identification of separate units of accounting after consideration of combining and/or segmenting contracts and allocation of the arrangement consideration to the units of accounting on the basis of their relative selling price. Revenue under such contracts is recognized based upon the levels of services delivered in the periods in which they are provided. Upfront fees for the contract set-up activities are deferred and recognized ratably over the period of performance. Costs are expensed as incurred except for direct and incremental set-up costs that are capitalized and amortized over the life of the agreement (see Outsourcing Contract Costs below). See the section below regarding software transactions that include multiple elements.
								The Company provides these services under time and materials, cost-reimbursable, unit-price and fixed-price contracts, the revenue for which is recognized in the following manner:
								Time and materials contracts - Revenue is recorded at agreed-upon billing rates at the time services are provided.
								Cost-reimbursable contracts - Revenue is recorded at the time costs are incurred and associated fees are recognized when probable and estimable by applying an estimated factor to costs as incurred, such factor being determined by the contract provisions and prior experience.
								Unit-price contracts - Revenue is recognized on unit-price contracts based on unit metrics multiplied by the agreed upon contract unit price or when services are delivered.
								Fixed-price contracts - For certain fixed-price contracts, revenue is recognized under the percentage-of-completion method as described below; these include certain software development projects, all long-term construction-type contracts, and certain fixed-price arrangements with the U.S. federal government. For other fixed-price contracts, revenue is recognized based on the proportion of the services delivered to date as a percentage of the total services to deliver over the contract term. If output or input measures are not available or cannot be reasonably estimated, revenues are recognized ratably over the contract term.
								Under the percentage-of-completion method, progress towards completion is measured based on either achievement of specified contract milestones, costs incurred as a proportion of estimated total costs, or other measures of progress when available. Profit in a given period is reported at the estimated profit margin to be achieved on the overall contract. This method can result in the recognition of unbilled receivables, the deferral of costs as work in process, or deferral of profit on these contracts. Contracts that require estimates at completion using the percentage-of-completion method accounted for approximately 17.9% of the Company's revenues for fiscal 2013. Management regularly reviews project profitability and underlying estimates. Revisions to the estimates at completion are reflected in results of operations as a change in accounting estimate in the period in which the facts that give rise to the revision become known by management. Provisions for estimated losses at completion, if any, are recognized in the period in which the loss becomes evident. The provision includes estimated costs in excess of estimated revenue and any profit margin previously recognized.
								Multiple-element software sales - For multiple-element arrangements that involve the sale of CSC proprietary software, post contract customer support, and other software-related services, vendor-specific objective evidence (VSOE) of fair value is required to allocate and recognize revenue for each element. VSOE of fair value is determined based on the price charged where each deliverable is sold separately. In situations where VSOE of fair value exists for all undelivered elements but not a delivered element (typically the software license element), the residual method is used to allocate revenue to the undelivered elements equal to their VSOE value with the remainder allocated to the delivered element. If significant customization is required, and VSOE is available to support accounting for the software as a separate unit of account, software revenue is recognized as the related software customization services are performed in accordance with the percentage-of-completion method described above. In situations where VSOE of fair value does not exist for all of the undelivered software-related elements, revenue is deferred until only one undelivered element remains and then recognized following the pattern of delivery of the final undelivered element.
								Depreciation and Amortization
								The Company’s depreciation and amortization policies are as follows:
								Property and Equipment:
								Buildings	Up to 40 years
								Computers and related equipment	3 to 5 years
								Furniture and other equipment	2 to 15 years
								Leasehold improvements	Shorter of lease term or useful life
								Software	2 to 10 years
								Outsourcing contract costs	Contract life, excluding option years
								Customer related intangibles	Expected customer service life
								Acquired contract related intangibles	Contract life and first contract renewal, where applicable
								The cost of property and equipment, less applicable residual values, is depreciated using predominately the straight-line method. Depreciation commences when the specific asset is complete, installed and ready for normal use. Depreciation expense for fiscal years 2013, 2012, and 2011 was $709 million, $754 million, and $685 million, respectively.
								Software and outsourcing contract costs are amortized using predominately the straight-line method. Acquired contract related and customer related intangible assets are amortized in proportion to the estimated undiscounted cash flows projected over the estimated life of the asset or on a straight-line basis if such cash flows cannot be reliably estimated.
								Software Development Costs
								The Company capitalizes costs incurred to develop commercial software products after technological feasibility has been established. Costs incurred to establish technological feasibility are charged to expense as incurred. Enhancements to software products are capitalized where such enhancements extend the life or significantly expand the marketability of the products. Amortization of capitalized software development costs is determined separately for each software product. Annual amortization expense is calculated based on the greater of (a) the ratio of current gross revenues for each product to the total of current anticipated future gross revenues for the product or (b) the straight-line method over the estimated economic life of the product.
								Unamortized capitalized software costs associated with commercial software products are regularly evaluated for impairment on a product-by-product basis by a comparison of the unamortized balance to the product’s net realizable value. The net realizable value is the estimated future gross revenues from that product reduced by the related estimated future costs. When the unamortized balance exceeds the net realizable value, the unamortized balance is written down to the net realizable value and an impairment charge is recorded.
								The Company capitalizes costs incurred to develop internal-use computer software. Internal and external costs incurred in connection with development of upgrades or enhancements that result in additional functionality are also capitalized. These capitalized costs are amortized on a straight-line basis over the estimated useful life of the software. Purchased software is capitalized and amortized over the estimated useful life of the software.
								Outsourcing Contract Costs
								Costs on outsourcing contracts, including costs incurred for bid and proposal activities, are generally expensed as incurred. However, certain costs incurred upon initiation of an outsourcing contract are deferred and expensed over the contract life. These costs represent incremental external costs or certain specific internal costs that are directly related to the contract acquisition or transition activities. Such capitalized costs can be separated into two principal categories: contract acquisition costs and transition/set-up costs. The primary types of costs that may be capitalized include labor and related fringe benefits, subcontractor costs, travel costs, and premiums on asset purchases.
								Premiums are amounts paid to customers in excess of the fair market value of assets acquired. Fixed assets acquired in connection with outsourcing transactions are capitalized at fair value and depreciated consistent with the fixed asset policies described above. Premiums paid are capitalized as outsourcing contract costs and amortized over the contract life. The amortization of outsourcing contract cost premiums is accounted for as a reduction in revenue. The second principal category of capitalized outsourcing costs is transition/set-up costs. Such costs are primarily associated with the installation of systems and processes and are amortized over the contract life.
								In the event indications exist that an outsourcing contract cost balance related to a particular contract may be impaired, undiscounted estimated cash flows of the contract are projected over its remaining term and compared to the associated long-lived asset group including the unamortized outsourcing contract cost balance. If the projected cash flows are not adequate to recover the unamortized cost balance of the asset group, the balance would be adjusted based on the fair value of the long-lived assets group in the period such a determination is made. The primary indicator used to determine when impairment testing should be performed is when a contract is materially underperforming, or is expected to materially underperform in the future, as compared to the original bid model or subsequent annual budgets.
								Terminations of outsourcing contracts, including transfer of assets either back to the customer or to another IT provider, prior to the end of their committed contract terms, are infrequent due to the complex transition of personnel, assets, methodologies, and processes involved with outsourcing transactions. In the event of an early termination, the Company and the customer, pursuant to certain contractual provisions, engage in discussions to determine the recovery of unamortized contract costs, lost profits, transfer of personnel, rights to implemented systems and processes, as well as other matters.
								Stock-Based Compensation
								The Company provides different forms of stock-based compensation to its employees and nonemployee directors. For awards settled in shares, the Company recognizes compensation expense based on the grant-date fair value net of estimated forfeitures. For awards settled in cash, the Company recognizes compensation expense based on the fair value at each reporting date net of estimated forfeitures. The Company recognized stock-based compensation expense for fiscal 2013, fiscal 2012, and fiscal 2011 as follows:
										Twelve Months Ended
								(Amounts in millions)		March 29, 2013				March 30, 2012			April 1, 2011
								Cost of services		$	22			$	15		$	12
							Selling, general and administrative		27				21			44
							Total		$	49			$	36		$	56
							Total, net of tax		$	31			$	23		$	35
							The Company’s overall stock-based compensation granting practice has not changed year-over-year, except that with fiscal 2012's long-term incentive program, service-based restricted stock units (RSUs) and performance-based RSUs represent a larger portion of total stock-based compensation awards than in the past.
							The increase in fiscal 2013 stock-based compensation expense was primarily due to performance-based RSUs granted in fiscal 2013 that increased the expense by $15 million. This increase was partially offset by a $3 million reduction of expense as a result of adjustments for expected achievement of the specified performance criteria for performance-based RSUs granted in previous fiscal years. Fiscal 2012 stock-based compensation expense included a $12 million reduction to expense for expected achievement of the specified performance criteria for performance-based RSUs granted in previous fiscal years. There were no such adjustments in fiscal 2011.
							The Company periodically evaluates its significant assumptions used in the fair value calculation. Beginning in fiscal 2011, the Company modified certain underlying assumptions in the fair value calculations, which did not have a material impact on the fair value calculations, as described below.
							The Company uses the Black-Scholes-Merton model in determining the fair value of options granted. The expected term is calculated based on the Company’s historical experience with respect to its stock plan activity in combination with an estimate of when vested and unexercised option shares will be exercised. The Company uses separate assumptions for the expected term of options granted based on two separate job tier classifications which had distinct historical exercise behavior. This resulted in separate fair value calculations by job tier. The risk-free interest rate is based on the zero coupon interest rate of U.S. government issued Treasury strips with a period commensurate with the expected term of the options. In determining the overall risk-free interest rate for fiscal 2013, a range of interest rates from 0.82% to 1.44% was applied depending on the expected life of the grant. The Company continued to base expected volatility on a blended approach using an equal weighting of implied volatility and historical volatility. However, beginning with the first quarter of fiscal 2011, the historical volatility calculation was based on the Company’s six-year and seven-year historical daily closing price, rather than the ten-year historical used in prior periods, in order to bring this factor more closely into alignment with the expected terms of the stock options. The range of volatility used for fiscal 2013 was 32% to 38%. The dividend yield assumption was added concurrent with the introduction of a cash dividend in fiscal 2011 and is based on the respective fiscal year dividend payouts. Forfeitures are estimated based on historical experience and adjustments are made annually to reflect actual forfeiture experience.
							The weighted average grant date fair values of stock options granted during fiscal 2013, fiscal 2012, and fiscal 2011 were $7.37, $10.17, and $12.95 per share, respectively. In calculating the compensation expense for its stock incentive plans, the Company used the following weighted average assumptions:
								Fiscal Year
								2013			2012			2011
							Risk-free interest rate	1.15	%		1.8	%		2.37	%
							Expected volatility	36	%		31	%		28	%
							Expected term (in years)	6.59			6.11			5.85
							Dividend yield	2.86	%		1.79	%		1.17	%
							During fiscal 2013, fiscal 2012, and fiscal 2011, the Company's actual tax benefit realized for tax deductions from exercising stock options was of $9 million, $7 million, and $11 million, respectively, and an excess tax benefit of $3 million, $2 million, and $6 million, respectively, related to all of its stock incentive plans.
							Acquisition Accounting and Goodwill
							Under acquisition accounting, the purchase price is allocated to the underlying tangible and intangible assets acquired and liabilities assumed based upon their respective fair market values, with the excess recorded as goodwill. Acquisition-related costs are expensed in the periods in which the costs are incurred, and the results of operations of acquired businesses are included in the Consolidated Financial Statements from the acquisition date.
							The Company tests goodwill for impairment on an annual basis, as of the first day of the second fiscal quarter, and between annual tests if circumstances change, of if an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. A significant amount of judgment is involved in determining whether an event indicating impairment has occurred between annual testing dates. Such indicators may include: a significant decline in expected future cash flows; a significant adverse change in legal factors or in the business climate; unanticipated competition; the disposal of a significant component of a reporting unit; and the testing for recoverability of a significant asset group within a reporting unit.
							The goodwill impairment test initially involves the assessment of qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is not more likely than not, then the subsequent two-step process is not required, although the Company has the option to bypass this initial qualitative assessment and proceed directly to step one of the two-step process. If the Company determines that it is more likely than not, then it proceeds with the subsequent two-step goodwill impairment testing process. The first step is to compare each reporting unit’s fair value to its carrying value. If the reporting unit’s fair value exceeds its carrying value, no further procedures are required. However, if a reporting unit’s fair value is less than its carrying value, an impairment of goodwill may exist, requiring a second step to measure the amount of impairment loss. In the second step, the reporting unit’s fair value is allocated to all of the assets and liabilities of the reporting unit, including any unrecognized intangible assets, in a hypothetical analysis to calculate the implied fair value of goodwill in the same manner as if the reporting unit was being acquired in a business acquisition. If the implied fair value of goodwill is less than the recorded goodwill, an impairment charge is recorded in operations for the difference.
							The Company estimates the fair value of each reporting unit using a combination of the income approach and the market approach. The income approach incorporates the use of a discounted cash flow method in which the estimated future cash flows and terminal values for each reporting unit are discounted to a present value using a discount rate. Cash flow projections are based on management's estimates of economic and market conditions, which drive key assumptions of revenue growth rates, operating margins, capital expenditures and working capital requirements. The discount rate in turn is based on the specific risk characteristics of each reporting unit, the weighted-average cost of capital and its underlying forecasts. The market approach estimates fair value by applying performance-metric multiples to the reporting unit's prior and expected operating performance. The multiples are derived from comparable publicly traded companies that have operating and investment characteristics similar to the reporting unit. If the fair value of the reporting unit derived using the income approach is significantly different from the fair value estimate using the market approach, the Company reevaluates its assumptions used in the two models. The fair values determined by the market approach and income approach, as described above, are weighted to determine the fair value for each reporting unit. The weighted values assigned to each reporting unit are driven by two primary factors: 1) the number of comparable publicly traded companies used in the market approach, and 2) the similarity of the operating and investment characteristics of the reporting units to the comparable publicly traded companies used in the market approach.
							In order to assess the reasonableness of the calculated reporting unit fair values, the Company also compares the sum of all of its reporting units’ fair values to the Company's market capitalization (per-share stock price multiplied by the number of shares outstanding) and calculates an implied control premium (the excess of the sum of the reporting units’ fair values over the market capitalization). The Company evaluates the reasonableness of the control premium by comparing it to control premiums of recent comparable transactions. If the implied control premium is not reasonable in light of these recent transactions, the Company reevaluates its fair value estimates of the reporting units by adjusting the discount rates and/or other assumptions. As a result, when CSC’s stock price is low, this reevaluation can result in lower estimated fair values of the reporting units.
							Fair Value
							The Company uses the fair value measurement guidance to value certain of its assets and liabilities. Under this guidance, assets and liabilities are required to be valued based on assumptions used by a market participant, consistent with the following hierarchy of inputs:
							Level 1—	Quoted prices unadjusted for identical assets or liabilities in an active market.
							Level 2—	Inputs other than quoted prices that are observable, either directly or indirectly, for similar assets or liabilities.
							Level 3—	Unobservable inputs that reflect the entity’s own assumptions which market participants would use in pricing the asset or liability.
							The assets and liabilities which are valued using the fair value measurement guidance, on a recurring basis, include the Company’s money market funds and money market deposits, time deposits, short-term investments, pension assets, and foreign currency derivatives comprised of forward and option contracts. The fair value of the forward contracts is based on quoted prices for similar but not identical derivative financial instruments; as such, the inputs are considered Level 2 inputs. Option contracts are valued using inputs which are based on quoted pricing intervals from external valuation models, which do not involve management judgment and as such, these inputs are considered Level 2 inputs. Certain pension assets are valued using model based pricing methods that use observable market data; as such these inputs are considered Level 2 inputs. There were no significant assets or liabilities measured at fair value on a recurring basis using significant unobservable (Level 3) inputs.
							Certain assets and liabilities are measured at fair value on a non-recurring basis. These include acquired assets and liabilities in a business combination, equity method investments, asset retirement obligations, long-lived assets and goodwill, which are recognized at fair value to the extent that they are deemed to be impaired or are classified as long-lived assets held to be disposed of by sale. The fair value in these instances is determined using Level 3 inputs.
							Receivables
							Receivables consist of amounts billed and currently due from customers, amounts earned but unbilled (including contracts measured under the percentage-of-completion method of accounting), amounts retained by the customer until the completion of a specified contract, completion of U.S. federal government audit activities audit activities, negotiation of contract modification, and claims.
							Allowances for uncollectible billed trade receivables are estimated based on a combination of write-off history, aging analysis and any specific known collectability issues. Unbilled amounts under contracts in progress that are recoverable do not have an allowance for credit losses. Adjustments to unbilled amounts under contracts in progress related to credit quality, should they occur, would be recorded as a reduction of revenue.
							Impairment of Long-Lived Assets
							Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be recoverable. Recoverability of long-lived assets or groups of assets is assessed based on a comparison of the carrying amount to the estimated future net cash flows. If estimated future undiscounted net cash flows are less than the carrying amount, an expense is recorded in the amount, if any, required to reduce the carrying amount to fair value. Fair value is determined based on a discounted cash flow approach or, when available and appropriate, to comparable market values. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.
							Income Taxes
							Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities. The Company maintains valuation allowances when, based on the weight of available evidence, it is more likely than not that all or a portion of a deferred tax asset will not be realized. Changes in valuation allowances from period to period are included in the Company’s tax provision in the period of change. In determining whether a valuation allowance is warranted, the Company takes into account such factors as prior earnings history, expected future earnings, carryback and carryforward periods, and tax strategies that could potentially enhance the likelihood of realization of a deferred tax asset.
							The Company recognizes uncertain tax positions in the financial statements when it is more likely than not that the tax position will be sustained upon examination. Uncertain tax positions are measured based on the probabilities that the uncertain tax position will be realized upon final settlement (see Note 10).
							Cash and Cash Equivalents
							The Company considers investments with an original maturity of three months or less to be cash equivalents. The Company’s cash equivalents consist of time deposits, money market funds and money market deposit accounts with a number of institutions that have high credit ratings.
							Cash Flows
							Cash payments for interest on indebtedness and cash payments for taxes on income are as follows:

							Capital expenditures through capital lease obligations		181				270			289
							Assets acquired under long-term financing		26				32			115
							Non-cash financing activities include common stock dividends of $30 million which are declared but not yet paid as of March 29, 2013.
							Foreign Currency
							The Company has determined that, generally, the local currency of its foreign affiliates is their functional currency. Accordingly, the assets and liabilities of the foreign affiliates are translated from their respective functional currency to U.S. dollars using year-end exchange rates, income and expense accounts are translated at the average rates in effect during the year, and equity accounts are translated at historical rates. The resulting translation adjustment is reported in the Statement of Other Comprehensive Income and recorded as part of accumulated other comprehensive income (AOCI). The amount of currency translation adjustment included in AOCI, for the years ended March 29, 2013, March 30, 2012 and April 1, 2011, was $(83) million (net of taxes of $12 million), $(124) million (net of taxes of $1 million) and $261 million (net of taxes of $3 million), respectively.
							To manage the exposure to movements in foreign currency exchange rates, the Company uses foreign currency forward contracts and option contracts (see Note 7). The use of these derivative instruments is intended to offset, to the extent possible, the gains and losses from remeasurement of the Company’s foreign currency denominated monetary assets and liabilities. Gains and losses from remeasurement of the Company’s foreign currency denominated assets and liabilities, and remeasurement and settlement of the related foreign currency derivatives are recorded in Other (income) expense.
							Earnings (Loss) Per Share
							Basic earnings (loss) per common share (EPS) are computed using the weighted average number of common shares outstanding during the period. Diluted EPS reflect the incremental shares issuable upon the assumed exercise of stock options and equity awards.

							The computation of diluted EPS does not include stock options which are antidilutive, as their exercise price exceeded the average market price of the Company’s common stock. The number of shares related to such stock options were 14,755,024, 17,592,316, and 9,431,834, for the years ended March 29, 2013, March 30, 2012, and April 1, 2011, respectively. In addition, the computation of diluted EPS for the year ended March 30, 2012, excluded options to purchase 442,228 shares of common stock and 1,064,959 RSUs whose effect, if included, would have been anti-dilutive due to the Company’s net loss.
							New Accounting Standards
							During fiscal year 2013, the Company adopted the following recent Accounting Standard Updates (ASUs):
							On June 16, 2011, the FASB issued ASU 2011-05, “Presentation of Comprehensive Income,” which revises the manner in which entities present comprehensive income in their financial statements. The new guidance removes the presentation options in ASC 220 "Comprehensive Income" and requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. The Company adopted the amendments in this update effective at the beginning of fiscal 2013 using the two-statement approach.
							On September 15, 2011, the FASB issued ASU 2011-08, “Testing Goodwill for Impairment,” which revises guidance on testing goodwill for impairment. The amendments in the ASU allow an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If an entity determines that it is not more likely than not, then performing the two-step impairment is unnecessary. However, if the entity concludes that fair value is more likely than not less than carrying value, then it is required to perform the first step of the two-step impairment test and calculate the fair value of the reporting unit to compare with the carrying value of the reporting unit as described in ASC 350-20-35-4. The entity may bypass the initial qualitative assessment for any reporting unit in any period and proceed directly to the first step of the two-step impairment test. The entity may resume performing the qualitative assessment in any subsequent period. The Company adopted the amendments in the update effective at the beginning of fiscal 2013 on a prospective basis, and they did not have a material effect on CSC's Consolidated Financial Statements.
							In December 2011, the FASB issued ASU 2011-11, “Disclosures about Offsetting Assets and Liabilities,” which was subsequently amended in January 2013 when the FASB issued ASU 2013-01 “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities”. Together, these ASUs provide guidance on disclosure of information pertaining to the offsetting (netting) of assets and liabilities in the financial statements. The amendments in these ASUs affect all entities that have financial instruments and derivative instruments that either (1) offset in accordance with either ASC 210-20-45 or ASC 815-10-45, or (2) are subject to an enforceable master netting arrangement or similar agreement. ASU 2011-11 amends the existing disclosure requirements on offsetting in ASC 210-20-50 by requiring disclosures relating to gross amounts of recognized assets and liabilities, the amounts that are offset, net amounts presented in the balance sheet, and amounts subject to an enforceable master netting arrangement or similar agreement. The amendments in these updates became effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The Company adopted the amendments in this update during the first quarter of fiscal 2014 and included additional disclosures in the Consolidated Condensed Financial Statements (see Note 7).
							Standards Issued But Not Yet Effective
							The following ASUs were recently issued but have not yet been adopted by CSC:
							On February 6, 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income”, which requires entities to report the effect of significant reclassifications out of AOCI on the respective line items in net income unless the amounts are not reclassified in their entirety to net income. For amounts that are not required to be reclassified in their entirety to net income in the same reporting period, entities are required to cross-reference other disclosures that provide additional detail about those amounts. The amendments are effective prospectively for fiscal years and interim periods within those years, beginning after December 15, 2012. The Company is currently evaluating the impact of the adoption of these amendments.
							In February 2013, the FASB issued ASU No. 2013-04, "Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date” which requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in this ASU also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. CSC will be required to adopt the amendments in this ASU beginning in fiscal 2015. We are currently evaluating the impact that the adoption may have on CSC's Consolidated Financial Statements.
							In March 2013, the FASB issued ASU No. 2013-05, Foreign Currency Matters (Topic 830): “Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity” which resolves the diversity in practice about whether Subtopic 810-10, Consolidation - Overall, or Subtopic 830-30, Foreign Currency Matters - Translation of Financial Statements, applies to the release of the cumulative translation adjustment into net income when a parent either sells a part of or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. In addition, the amendments resolve the diversity in practice for the treatment of business combinations achieved in stages (i.e. step acquisitions) involving a foreign entity. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. CSC will be required to adopt the amendments in this ASU beginning in fiscal 2015. The adoption of the amendments of these updates is not expected to have a material effect on CSC's Consolidated Financial Statements.

	As previously disclosed, the Company initiated an investigation into out of period adjustments resulting from certain accounting errors in our former Managed Services Sector (MSS) segment, primarily involving accounting irregularities in the Nordic region. Initially, the investigation was conducted by Company personnel, but outside Company counsel and forensic accountants retained by such counsel later assisted in the Company's investigation. On January 28, 2011, the Company was notified by the SEC's Division of Enforcement that it had commenced a formal civil investigation relating to these matters, which investigation has been expanded to other matters subsequently identified by the SEC, including matters specified in subpoenas issued to the Company from time to time by the SEC's Division of Enforcement as well as matters under investigation by the Audit Committee, as further described below. The Company is cooperating in the SEC's investigation.

The Company is cooperating in the SEC's investigation.
	On May 2, 2011, the Audit Committee commenced an independent investigation into the matters relating to the former MSS segment and the Nordic region, matters identified by subpoenas issued by the SEC's Division of Enforcement, and certain other accounting matters identified by the Audit Committee and retained independent counsel to represent CSC on behalf of, and under the exclusive direction of, the Audit Committee in connection with such independent investigation. Independent counsel retained forensic accountants to assist with their work.

Independent counsel retained forensic accountants to assist with their work. Independent counsel also represents CSC on behalf of, and under the exclusive direction of, the Audit Committee in connection with the investigation by the SEC's Division of Enforcement.
	The Audit Committee’s investigation was expanded to encompass (i) the Company’s operations in Australia, (ii) certain aspects of the Company’s accounting practices within its Americas Outsourcing operation, and (iii) certain of the Company’s accounting practices that involve the percentage-of-completion accounting method, including the Company’s contract with the U.K. National Health Service (NHS). In the course of the Audit Committee's expanded investigation, accounting errors and irregularities were identified. As a result, certain personnel have been reprimanded, suspended, terminated and/or have resigned. The Audit Committee determined in August 2012 that its independent investigation was complete. The Audit Committee instructed its independent counsel to cooperate with the SEC's Division of Enforcement by completing production of documents and providing any further information requested by the SEC's Division of Enforcement.

	In addition to the matters noted above, the SEC's Division of Enforcement is continuing its investigation involving its concerns with certain of the Company's prior disclosure and accounting determinations with respect to the Company's contract with the NHS and the possible impact of such matters on the Company's financial statements for years prior to the Company's current fiscal year. The Company and the Audit Committee and its independent counsel are continuing to respond to SEC questions and to cooperate with the SEC's Division of Enforcement in its investigation of prior disclosures of the Company's contract with the NHS.

	Fiscal 2014 Adjustments
															Fiscal 2013 Adjustments Financial Impact Summary
	During the first quarter of fiscal 2014, the Company identified and recorded net adjustments increasing income from continuing operations, before taxes by $9 million that should have been recorded in prior fiscal years. This net impact on income from continuing operations before taxes comprised of the following:
															During fiscal 2013, the Company identified and recorded net adjustments decreasing income from continuing operations before taxes by $6 million that should have been recorded in prior fiscal years. This net impact on income from continuing operations before taxes for fiscal 2013 is comprised of the following:
	•	net adjustments decreasing income from continuing operations before taxes by $13 million resulting primarily from revenues and costs in its GBS segment;													•	net adjustments decreasing fourth quarter pre-tax income by $9 million resulting primarily from the correction of inappropriately capitalized operating costs originating from the Company's GIS segment, a software revenue recognition correction originating from the Company's GBS segment and the correction of understated payroll and related expenses at Corporate;
	•	net adjustments increasing income from continuing operations before taxes by $8 million resulting from the correction of payroll expenses within its GBS segment; and													•	net adjustments decreasing third quarter pre-tax income by $1 million primarily resulting from the correction of useful lives of property and equipment in service at a GIS contract that were inconsistent with established CSC accounting conventions;
	•	net adjustments increasing income from continuing operations before taxes by $14 million resulting primarily from adjustments identified by the Company late in the fiscal 2013 closing process.													•	net adjustments increasing second quarter pre-tax income by $5 million primarily resulting from the correction of accounting errors identified by the Company related to costs incurred under the NHS contract (see below for more discussion of out of period adjustments related to the Company's NHS contract); and
	Adjustments recorded during the first quarter of fiscal 2014 that should have been recorded in prior fiscal years decreased income from continuing operations by $2 million. The difference is attributable to the tax effect of the adjustments described above, and $2 million of tax expense related to net adjustments that should have been recorded in prior periods.														•	net adjustments decreasing first quarter pre-tax income by $1 million primarily resulting from the corrections of fiscal 2012 revenue recognized on a software contract in the Company's GBS segment, corrections of fiscal 2012 restructuring cost accruals originating primarily from the Company's GBS and GIS segments and corrections to record adjustments that were identified late in the close process but not included in the Company's consolidated fiscal 2012 financial statements
	The impact of out of period adjustments recorded during the first quarter of fiscal 2014 on select line items of the Consolidated Condensed Statements of Operations for the quarter ended June 28, 2013, using the rollover method, is shown below:														Adjustments recorded during fiscal 2013 that should have been recorded in prior fiscal years increased income from continuing operations by $7 million. This increase is attributable to the tax effect of the adjustments described above and $5 million of discrete tax benefits that should have been recorded in prior fiscal years. The discrete tax benefits are primarily attributable to the adjustment of the deferred tax liability related to intellectual property assets.

			Quarter Ended June 28, 2013
	(Amounts in millions, except per-share amounts)		As Reported			Adjustments			Amount Adjusted						As previously disclosed in fiscal 2012 and in the first quarter of fiscal 2013, the Company had identified certain additional items related to the investigation of the Company's use of the percentage-of-completion accounting method used on the NHS contract. During the second quarter of fiscal 2013, based on its analysis of these items, the Company recorded net credits of $9 million in pre-tax out of period adjustments impacting prior fiscal years. During the third quarter of fiscal 2013, the Company identified additional prior period errors. Such errors identified in the third quarter, which were self-correcting in the third quarter of fiscal 2012, have no impact on income from continuing operations before taxes for fiscal 2013. The accounting errors identified during fiscal 2013 are primarily related to either costs incurred under the contract or the estimation of contract revenues and costs at completion, which resulted in the overstatement of income from continuing operations before taxes. The Company has concluded that there is no cumulative impact of this overstatement as a result of the $1.5 billion specified contract charge recorded as of December 30, 2011 being overstated by the same amount.
						Increase/			for Removal
						(Decrease)			of Errors						The Company has concluded that the errors identified during fiscal 2013 do not appear to have any impact on amounts charged to the NHS. Based on information provided by independent counsel, the Company believes that a small portion of such adjustments should be characterized as intentional accounting irregularities. The impact on income (loss) from continuing operations before taxes of the out of period adjustments identified in fiscal 2013 related to the Company's NHS contract is attributable to the following prior fiscal years:
	Revenue		$	3,254		$	19		$	3,273

	The out of period adjustments impacting income from continuing operations before taxes recorded by the Company in the three months ended June 28, 2013 are related to the following consolidated balance sheet line items:														Out of period adjustments recorded in fiscal 2013 had the following impact on select line items of the Consolidated Statements of Operations for the twelve months ended March 29, 2013 under the rollover method:
	•	Accounts receivable ($1 million decrease);
																	Twelve Months Ended March 29, 2013
	•	Prepaid expenses and other current assets ($2 million increase);													(Amounts in millions, except per-share amounts)		As Reported			Adjustments			Amount Adjusted

The Company has determined that the impact of the consolidated out of period adjustments recorded during the first quarter of fiscal 2014 is immaterial to the consolidated results, financial position and cash flows for the first quarter of fiscal 2014 and prior years. Consequently, the cumulative effect of these adjustments was recorded during the first quarter of fiscal 2014.
														Restructuring costs		264			5			269
Fiscal 2013 Adjustments
														Interest expense		183			—			183
During the first quarter of fiscal 2013, the Company recorded net adjustments primarily in its NPS and GBS segments reducing income from continuing operations before taxes by $1 million that should have been recorded in prior fiscal years. The out of period adjustments recorded in the first quarter of fiscal 2013 consisted of $17 million of charges reducing income from continuing operations before taxes and $16 million of adjustments increasing income from continuing operations before taxes. These net adjustments increased income from continuing operations by $5 million. The difference is attributable to the tax effect of the adjustments described above, and a $2 million tax benefit recorded in the first quarter of fiscal 2013 but related to prior periods.
														Other (income) expense		(25		)	—			(25		)
During subsequent periods, the Company recorded out of period adjustments primarily in its GBS and GIS segments that should have been recorded in the first quarter of fiscal 2013. Had such adjustments been recorded in the first quarter of fiscal 2013, income from continuing operations before taxes would have decreased by $2 million, of which $4 million relates to adjustments identified during the first quarter of fiscal 2014. Had such adjustments been recorded in the first quarter of fiscal 2013, there would have been no net effect on income from continuing operations.

														Fiscal 2012 Adjustments Financial Impact Summary
The out of period adjustments impacting income from continuing operations before taxes recorded by the Company in the three months ended June 29, 2012 are related to the following consolidated balance sheet line items:
														During fiscal 2012, the Company recorded various pre-tax adjustments that should have been recorded in prior fiscal years. The aggregate fiscal 2012 adjustments increased the loss from continuing operations before taxes by $79 million ($63 million net of tax) and were comprised of $13 million of charges relating to operations in the Nordic region, $23 million of charges relating to the Company's operations in Australia, and $25 million of charges originating from the NHS contract in the Company's GBS segment. Additionally, $16 million and $2 million of charges were recorded in the NPS segment and other operations of the Company, respectively. The fiscal 2012 out of period adjustments primarily related to the Company’s GIS and GBS segments, with $24 million and $39 million of adjustments within GIS and GBS, respectively. Further adjustments were identified and recorded in fiscal 2013 related to fiscal 2012 that increased the net error by $7 million.
•	Accounts receivable ($2 million increase);
														Nordic Region
•	Prepaid expenses and other current assets ($2 million decrease);													The Company attributes the $13 million in pre-tax adjustments recorded in the Nordic region in fiscal 2012 to miscellaneous errors and not to any accounting irregularities or intentional misconduct other than a $1 million operating lease adjustment noted in the first quarter of fiscal 2012 which was a refinement of an error previously corrected and reported in fiscal 2011.
•	Property and equipment ($3 million decrease);													Australia
														As previously disclosed, in the course of the Australia investigation initiated in fiscal 2012, accounting errors and irregularities were identified. As a result, certain personnel in Australia have been reprimanded, terminated and/or resigned. The Company attributes the $23 million of pre-tax adjustments recorded in fiscal 2012 to either intentional accounting irregularities (intentional irregularities) or other accounting errors (Other Errors). Other Errors include both unintentional errors and errors for which the categorization is unclear. The categorizations were provided to the Company through the independent investigation. The impact of the adjustments on income (loss) from continuing operations before taxes is attributable to the following prior fiscal years:
•	Accrued payroll and related costs ($1 million decrease)
•	Deferred revenue ($7 million increase); and															Increase/(Decrease)
														(Amounts in millions)		Fiscal 2008 &			Fiscal 2009 (unaudited)			Fiscal 2010			Fiscal 2011			Total
•	Accrued expenses and other current liabilities ($10 million decrease).															Prior (unaudited)
														Intentional irregularities		$	10		$	(7	)	$	(4	)	$	1		$	—
The Company determined that the impact of the consolidated out of period adjustments recorded in the first quarter of fiscal 2013 was immaterial to the consolidated results, financial position and cash flows for the first quarter of fiscal 2013 and prior years. Consequently, the cumulative effect of these adjustments was recorded during the first quarter of fiscal 2013.
														Other Errors		(7		)	(16		)	3			(3		)	(23		)
																$	3		$	(23	)	$	(1	)	$	(2	)	$	(23	)
														NHS
														As previously disclosed, in fiscal 2012, $25 million of out of period adjustments reducing income from continuing operations related to the Company's NHS contract were identified and recorded. During the course of the investigation in fiscal 2012 of the percentage-of-completion accounting method used on the Company's NHS contract, certain accounting errors were identified related to costs incurred under the contract, which resulted in errors in the recognition of income from continuing operations that would have reduced by approximately $24 million the $1.5 billion write-off recorded by the Company in the third quarter of fiscal 2012. Although the Company has concluded that these errors do not appear to have any impact on amounts charged to the NHS, the errors have impacted the operating income recognized on the NHS contract. The exclusion of certain costs incurred under the contract caused the estimated margin at completion, which determines the operating income that is booked when revenue milestones are achieved, to be overstated. Although the Company has concluded that there is no cumulative impact as a result of the $1.5 billion charge relating to the NHS contract recorded as of December 30, 2011, operating income from fiscal year 2007 through and including fiscal 2011 has been overstated by a total of approximately $24 million and, therefore, the charge taken by the Company as of December 30, 2011 was overstated by approximately the same amount.
														Certain additional items had been identified related to the NHS contract that could have had an effect on the amount and the allocation of the out of period adjustments for fiscal 2012 and prior fiscal years. These additional items were subject to further investigation and therefore were not recorded in fiscal 2012. See our discussion of fiscal 2013 adjustments above for further information regarding the impact of such items.
														Certain CSC finance employees based in the U. K. were aware prior to fiscal 2012 of the aforementioned errors, but those employees failed to appropriately correct the errors. Therefore, the Company has classified these errors as intentional. Such categorization was provided to the Company through the independent investigation. As a result, certain personnel have been suspended.
														The impact on income (loss) from continuing operations before taxes of the $25 million of out of period adjustments identified in fiscal 2012 related to the Company's NHS contract is attributable to the following prior fiscal years:
															Increase/(Decrease)
														(Amounts in millions)	Fiscal 2012 Adjustments
														Fiscal 2012	$	25
														Fiscal 2011	(7		)
														Fiscal 2010	(4		)
														Prior fiscal years (unaudited)	(14		)
														NPS
														As previously reported, in fiscal 2012 the Company identified and recorded pre-tax adjustments reducing income from continuing operations before taxes by $16 million. Such adjustments were identified by the Company and were primarily related to the percentage-of-completion accounting adjustments.
														Americas Outsourcing
														As previously disclosed, in the course of the independent investigation of Americas Outsourcing accounting practices, accounting conventions used by Americas Outsourcing relating to intraperiod cost allocations were determined to be unintentional accounting errors. The errors did not have an impact on a fiscal year basis. The Company also determined that other operating units employed similar practices and made necessary corrections.
														The following table summarizes the cumulative effect on the fiscal 2012 net loss attributable to CSC common shareholders of the consolidated out of period adjustments recorded during fiscal 2012 and fiscal 2013 under the rollover method. The amounts noted below also include certain adjustments that only impacted quarters (unaudited) within fiscal 2012, but had no net impact on the full year fiscal 2012 results:

														The out of period adjustments affecting loss from continuing operations before taxes during the twelve months ended March 30, 2012 under the rollover method are related to the following consolidated balance sheet line items:
														•	Accounts receivable ($66 million decrease);
														•	Prepaid expenses and other current assets ($44 million increase);
														•	Other assets ($6 million increase);
														•	Property and equipment ($29 million decrease);
														•	Accrued payroll and related costs ($2 million decrease);
														•	Accrued expenses and other current liabilities ($46 million increase); and
														•	Deferred revenue ($3 million decrease).
														The Company has determined that the impact of the consolidated out of period adjustments recorded in fiscal 2012 and fiscal 2013 is immaterial to the consolidated results, financial position and cash flows for fiscal 2012 and prior years. Consequently, the cumulative effect of these adjustments was recorded during fiscal 2012 and fiscal 2013.
														Fiscal 2011 Adjustments Financial Impact Summary
														During fiscal 2011, the Company recorded $52 million of pre-tax adjustments that should have been recorded in prior fiscal years. The total out of period adjustments recorded in fiscal 2011 were comprised of $92 million of charges reducing income from continuing operations before taxes originating out of the Company’s GBS and GIS operations in the Nordic region, and $40 million of adjustments increasing income from continuing operations before taxes, with $27 million of the $40 million within GIS. Further adjustments were identified and recorded in fiscal 2012 and 2013 related to fiscal 2011 that reduced the net error by $29 million and $22 million, respectively.
														Nordic Region
														As noted above, during fiscal 2011, the Company commenced an investigation into accounting irregularities in the Nordic region. Based upon the Company's investigation, review of underlying documentation for certain transactions and balances, review of contract documentation and discussions with Nordic personnel, the Company attributes the majority of the $92 million of pre-tax adjustments recorded in the Nordic region in fiscal 2011 to accounting irregularities arising from suspected intentional misconduct by certain former employees in our Danish subsidiaries. These accounting irregularities included the inappropriate capitalization of operating costs, the misapplication of U.S. GAAP and miscellaneous errors.
														The following table summarizes the cumulative effect on the fiscal 2011 net income attributable to CSC common shareholders of the consolidated out of period adjustments recorded during fiscal 2011, 2012 and 2013.

	Divestitures
	Discontinued Operations
	During fiscal 2013, CSC completed the divestiture of three businesses within its GBS Segment: the U.S.-based credit services business, the Italian consulting and system integration business, and an enterprise systems integration business in Malaysia and Singapore. These divestitures reflect the Company's ongoing service portfolio optimization initiative to focus on next-generation technology services and are presented in the Company's Consolidated Statements of Operations as discontinued operations.
	The Company received cash proceeds of $1,001 million for the sale of its U.S. based credit services business, including a $1 million working capital adjustment. For its sale of the enterprise system integration business, the Company received $90 million in cash and expects to receive another $14 million for working capital and other adjustments. For the disposal of its Italian consulting and system integration business, the Company paid $35 million (plus $8 million of cash included in the divested entity's net assets sold), but expects to receive $6 million back from the buyer for a purchase price adjustment. Both, the $14 million and $6 million described above were recorded as receivables.
	These three divestitures resulted in a total pre-tax gain of $769 million (after-tax gain of $417 million), representing the excess of the net proceeds over the carrying value of the net assets of the divested businesses and transaction costs of $11 million. The divested assets and liabilities included current assets of $129 million, property and equipment and other long-lived assets of $11 million, goodwill of $241 million, and liabilities of $85 million.
	During fiscal 2012, CSC recorded a pre-tax loss from discontinued operations of $2 million to reflect purchase price adjustments in accordance with the purchase agreement related to the fourth quarter fiscal 2011 divestiture discussed below. In fiscal 2012, CSC also recorded a $3 million adjustment to the taxes on gain on discontinued operations recorded in fiscal 2011. The adjustment reflects a change in the estimated tax provision made in fiscal 2011.
	During fiscal 2011, CSC completed the divestiture of two businesses within its NPS segment whose ultimate customer was the U.S. federal government. One divestiture resulted in cash consideration of $56 million, and the second divestiture resulted in cash consideration of $65 million, of which $63 million was received in fiscal 2011 and the remaining $2 million was collected in fiscal 2012. Both of the divestitures were driven by the Governmental Organizational Conflict of Interest concerns. The divestitures resulted in total pre-tax gains of $59 million (after-tax gains of approximately $28 million) representing the excess of the proceeds over the carrying value of the net assets of the divested businesses (which included current assets of $38 million, property and equipment and other long-lived assets of $8 million, goodwill of $23 million, liabilities of $12 million), net of transaction costs of $5 million.
	Following is the summary of the results of the discontinued operations (1):
		Twelve Months Ended

	Gain on disposition, net of taxes	417		1			28
	Income from discontinued operations, net of taxes	$	481	$	166		$	126
	(1) The results of discontinued operations noted above include the operating results of two businesses divested in fiscal 2014, as well as the business that CSC has committed to a plan to sell, that qualified to be presented as discontinued operations in fiscal 2014. See Note 21 for additional information regarding these three fiscal 2014 discontinued operations.
	In fiscal 2013, the primary difference between the book and tax gain on the sale of the U.S.-based credit services business was the write-off of approximately $241 million of goodwill, a majority of which was non-deductible for tax purposes. The income tax expense recorded includes an allocation of a deferred tax charge related to such goodwill. In addition, there was a significant tax benefit realized on the divestment of the Italian consulting and system integration business. The gain from the sale of the enterprise systems integration business in Malaysia and Singapore was exempt from income tax. In fiscal 2011, the primary difference between the book and tax gain on the sale of an NPS business was related to goodwill that was not tax deductible for tax purposes.
	For fiscal 2012, discontinued operations reflects a tax benefit of approximately $82 million due to the change in tax status of one of the Company's foreign subsidiaries. This change in tax status resulted in a deemed liquidation for U.S. tax purposes and triggered various deductions which resulted in an income tax benefit. This benefit was allocable to discontinued operations as such foreign subsidiary was disposed of during the current fiscal year.
	Other Divestiture
	In fiscal year 2013, the Company also sold Paxus, its Australian information technology staffing business unit, which was included in the Company's GBS Segment. This divestiture did not qualify to be presented as discontinued operations due to CSC's significant continuing business relationship with the divested entity.
	The total consideration for this divestiture was $79 million, of which $63 million was received in cash and $16 million was recorded as a receivable. This sale resulted in a pre-tax gain of $38 million, representing the excess of the proceeds over the carrying value of the net assets divested, net of transaction costs of $3 million. The divested assets and liabilities included current assets of $41 million, property and equipment and other long-lived assets of $2 million, and liabilities of $5 million. There was no tax expense or benefit on the gain on sale of Paxus because the Company had sufficient capital losses in its Australian business unit to completely offset the capital gain.

	Fiscal 2013 Acquisition					Fiscal 2013 Acquisition
	In the second quarter of fiscal 2013, CSC acquired a privately-held entity for $35 million in an all-cash transaction. The entity was acquired primarily to enhance CSC's capabilities in Big Data processing and analytics, a next-generation service offering. The purchase price was allocated to net assets acquired based on estimates of fair value at the date of acquisition: $4 million to current assets, $8 million to acquired intangible assets, $2 million to liabilities, and $25 million to goodwill. The goodwill is associated with the Company's NPS segment and is tax-deductible.					In the second quarter of fiscal 2013, CSC acquired a privately-held entity for $35 million in an all-cash transaction. The entity was acquired primarily to enhance CSC's strategy of offering customers greater value through data expertise and intellectual property. The purchase price was allocated to net assets acquired based on their estimated fair values at the date of acquisition as: $4 million to current assets, $8 million to acquired intangible assets, $2 million to liabilities, and $25 million to goodwill. The goodwill is associated with the NPS segment and is expected to be tax deductible. The pro forma financial information for this acquisition is not presented as this acquisition is not material to CSC’s consolidated results.
	The financial results of the acquired business have been included in the Company’s Consolidated Condensed Financial Statements from the date of acquisition. Pro forma financial information for this acquisition is not presented as it is not material to CSC’s consolidated results.					Fiscal 2012 Acquisitions
	Divestitures					iSOFT Acquisition
	Discontinued Operations					On July 29, 2011, CSC completed the acquisition of iSOFT Group Limited (iSOFT), a publicly-held company listed on the Australian Securities Exchange. iSOFT is a global healthcare information technology company providing advanced application solutions principally to secondary care providers across both the public and private sectors. The acquisition complements and strengthens CSC’s software products, healthcare integration and services portfolio, and its healthcare research and development capabilities.
	Fiscal 2014					CSC acquired all of the outstanding shares in iSOFT for cash consideration of $200 million and the assumption of debt of $315 million, of which $298 million was repaid immediately after the acquisition.  The acquisition was funded through CSC’s existing cash balances.
	On May 26, 2013, CSC entered into an agreement to sell its base operations, aviation and ranges services business unit, Applied Technology Division (ATD) within its NPS Segment, to a strategic investor. This disposition reflects CSC's ongoing service portfolio optimization initiative, and the results of ATD are presented as discontinued operations in the Consolidated Condensed Statements of Operations. As the transaction had not closed as of June 28, 2013, the assets and liabilities of ATD have been classified as held-for-sale in the Company's Consolidated Condensed Balance Sheet as follows: $144 million of current assets included within prepaid expenses and other current assets, $62 million of non-current assets including, $43 million of goodwill and $19 million other long-term assets included within other assets, $69 million of current liabilities included within accrued expenses and other current liabilities, and $37 million of non-current liabilities included within other long-term liabilities. The divestiture of ATD was completed on July 19, 2013 (see Note 18).					Prior to the acquisition, the Company and iSOFT had a subcontracting agreement related to the development and delivery of software and IT services under the Company’s NHS contract. The agreement was effectively settled upon the completion of the acquisition. The Company determined that the subcontract was at market and no settlement gain or loss was recognized on the pre-existing relationship.
	On May 21, 2013, CSC completed the divestiture of its flood insurance-related business process outsourcing practice (flood insurance BPO) to a financial investor for cash consideration of $43 million plus a net working capital adjustment receivable of $4 million, for a pre-tax gain on disposal of $25 million, representing the excess of the net proceeds over the carrying value of the net assets of the divested business and the related transaction costs. The divested assets and liabilities included current assets of $9 million included within prepaid expenses and other current assets, $14 million of non-current assets including, $12 million of goodwill and $2 million of other long-lived assets included within other assets, and current liabilities of $1 million included within accrued expenses and other current liabilities. This business was included in CSC's GBS Segment. The divestiture reflects CSC's focus on next-generation product and service offerings, and the results of this business have been included in the Company's Consolidated Condensed Statements of Operations as discontinued operations.					The results of iSOFT have been included in the Company’s consolidated financial statements from the date of acquisition within its GBS segment. For the twelve months ended March 30, 2012, iSOFT contributed revenues of $123 million and an operating loss of $79 million, including the effect of purchase accounting adjustments, primarily relating to amortization of intangibles. The operating loss was offset by currency gains of $18 million, resulting in an effective loss of $61 million before interest and taxes. The currency gains, which resulted from unhedged inter-company loans, are included in other income. The following unaudited pro forma summary presents consolidated information of the Company as if the acquisition of iSOFT had occurred on April 3, 2010 for all periods presented:

	The Company received cash proceeds of $1,003 million for the sale of its U.S.-based credit services business of which $2 million was received in the first quarter of fiscal 2014 for a subsequent net working capital adjustment. For its sale of the enterprise system integration business, the Company received $90 million in cash and expects to receive another $14 million for net working capital and other adjustments. For the disposal of its Italian consulting and systems integration business, the Company paid $35 million (plus $8 million of cash included in the divested entity's net assets sold) but expects to receive $5 million back from the buyer for a purchase price adjustment. Both the $14 million and $5 million described above are recorded as receivables.

	These three divestitures resulted in a total fiscal 2013 pre-tax gain of $769 million (after-tax gain of $417 million), representing the excess of the proceeds over the carrying value of the net assets of the divested businesses, net of transaction costs of $11 million. As noted above, there was an additional $2 million pre-tax gain recorded during the first quarter of fiscal 2014.

	The tax expense for the quarters ended June 28, 2013 and June 29, 2012 approximates the U.S. federal and state statutory income tax rate applied to income before tax as the operations were located in the U.S. The primary difference between the book and tax gains on the sale of the flood insurance BPO business was the write-off of approximately $12 million of goodwill, the majority of which was not deductible for tax purposes.

	During the fourth quarter of fiscal 2013, the Company sold Paxus, its Australian information technology staffing business unit. This divestiture did not qualify to be presented as discontinued operations because of CSC's significant continuing business relationship with the divested entity. The total consideration for this divestiture was $79 million, of which $63 million was received in cash and $16 million was recorded as a receivable at the end of fiscal 2013. Of the total receivable, the Company received, during the first quarter for fiscal 2014, cash of $10 million and offset $6 million against a current payable due to the buyer. This sale resulted in a pre-tax gain of $38 million, representing the excess of proceeds over the carrying value of the net assets divested, net of transaction costs of $3 million. The divested assets and liabilities included current assets of $41 million, property and equipment and other long-lived assets of $2 million, and liabilities of $5 million. There was no tax expense or benefit on the gain on sale of Paxus because the Company had sufficient capital losses in its Australian business unit, for which a valuation allowance had previously been provided, that completely offset the capital gain.					Total cash purchase price	$	200
						As of the acquisition date, the fair value of receivables approximated book value, which included billed and unbilled receivables and the historical allowance for uncollectible amounts of $10 million.

						Customer relationships	$	92		13-Oct
						Software	102			7-Feb
						Trade names	4			1
						Total intangible assets	$	198
						The entire amount of goodwill is associated with the Company’s GBS segment, and is attributable to expected increases in the Company’s market capabilities, synergies from combining operations, and the value of the acquired workforce. Of the estimated total goodwill, $71 million was estimated to be tax deductible.
						AppLabs Acquisition
						On September 13, 2011, CSC acquired AppLabs Technologies Private Limited (AppLabs), a Company headquartered in India which significantly enhances CSC’s capabilities in application testing services as well as shortening time-to-market. The AppLabs acquisition will complement CSC’s expertise in financial services, healthcare, manufacturing, chemical, energy and natural resources and technology and consumer verticals.
						CSC acquired all outstanding shares of AppLabs for cash consideration of $171 million, which was funded through CSC’s existing cash balances.
						The results of AppLabs have been included in the Company’s consolidated financial statements from the date of acquisition as part of the GBS segment. For the twelve months ended March 30, 2012, AppLabs contributed revenues of $60 million and net income of $2 million, including the effect of purchase accounting adjustments, primarily relating to amortization of intangibles. The pro forma financial information for this acquisition is not presented as this acquisition is not material to CSC’s consolidated results.
						The fair values of the assets acquired and liabilities assumed at the date of acquisition, including adjustments to the valuation of net assets acquired based on additional information that subsequently became available during fiscal 2012, are summarized as follows:

					(Amounts in millions)	Estimated			Estimated Useful Lives
						Fair Value			(Years)
					Customer relationships	$	25		8-Feb

					Total intangible assets	$	26
					The entire amount of goodwill is associated with the Company’s GBS segment and is attributable to expected increases in the Company’s market capabilities and the value of the acquired workforce. None of the goodwill was tax deductible.
					Other Acquisitions
					During fiscal 2012, CSC also acquired two other small privately-held entities for $28 million in all-cash transactions plus additional consideration of up to $2 million contingent on achievement of agreed revenue targets for future periods through the end of May 2014. The acquisitions will enhance CSC’s offerings in the healthcare information technology and financial services industries.
					The results of the acquired businesses have been included in the Company’s consolidated financial statements from the dates of acquisition. The pro forma financial information for these acquisitions is not presented as these acquisitions, both individually and in the aggregate, are not material to CSC’s consolidated results.
					The purchase prices were allocated to net assets acquired based on estimates of fair values at the dates of acquisition as: $8 million to current assets, $2 million to property and equipment, $7 million to intangible assets, $6 million to liabilities and $17 million to goodwill. Identified intangible assets consist primarily of customer related intangibles with useful lives of 4-10 years. Of the $17 million goodwill, $14 million is associated with the NPS segment and $3 million with the GBS segment. The $14 million goodwill associated with the NPS segment is expected to be tax deductible.
					During fiscal 2011, CSC acquired four privately-held companies for $156 million. Two of the acquisitions were related to CSC's NPS segment and enhance the Company's cyber security, intelligence and analysis capabilities that support the national security and intelligence communities. Two of the acquisitions were related to CSC's GBS segment and augment the Company's healthcare business process outsourcing, software design and development, and our consulting practice within the chemical, energy and natural resources markets. The purchase consideration for the acquisitions was allocated to the assets acquired and liabilities assumed, based on their respective fair values at the date of acquisition. The total purchase consideration was allocated as $17 million to current assets, $5 million to property and equipment and other long term assets, $22 million to customer-related intangible assets, $19 million to other intangible assets, $20 million to liabilities assumed, and $113 million to goodwill. Identified other intangible assets include software, noncompetition agreements, trade names and in-process research and development. The weighted average amortization period for the customer-related intangible assets ranges from seven to ten years, and for other intangible assets it ranges from three to eight years. Of the total goodwill, $72 million is associated with CSC’s NPS segment and $41 million with the GBS segment; $69 million of the total goodwill was tax deductible. The aggregate amount of acquisition costs for the transactions amounted to $1 million and was expensed as incurred.
					Pro forma financial information is not presented as the impact of these acquisitions was immaterial to CSC’s consolidated results.

	The Company's money market funds, money market deposit accounts and time deposits are reported in cash and cash equivalents; short-term investments and derivative assets are included in prepaid expenses and other current assets; and derivative liabilities are included in other accrued expenses. Gains and losses from changes in the fair value of derivative assets and liabilities are included in earnings and reported in other (income) expense. There were no transfers between Level 1 and Level 2.
	Derivative assets and liabilities include foreign currency forward contracts and currency options. The fair value of foreign currency forward contracts represents the estimated amount required to settle the contracts using current market exchange rates, and is based on the month-end foreign currency exchange rates and forward points. The fair value of currency options is estimated based on valuation models that use the original strike price, movement and volatility in foreign currency exchange rates, and length of time to expiration as inputs.

The fair value of currency options is estimated based on external valuation models that use the original strike price, movement and volatility in foreign currency exchange rates, and length of time to expiration as inputs.
	Assets and liabilities measured at fair value on a nonrecurring basis include goodwill, tangible assets, intangible assets, and other contract related long-lived assets. Such assets are reviewed quarterly for impairment indicators. If a triggering event has occurred, the assets are remeasured when the estimated fair value of the corresponding asset or asset group is less than the carrying value. The fair value measurements, in such instances, are based on significant unobservable inputs (Level 3). There were no significant impairments recorded during the quarter ended June 28, 2013.									Fair value measurements on a non-recurring basis
	Financial Instruments									Assets and liabilities measured at fair value on a nonrecurring basis include goodwill, tangible assets, intangible assets and other contract related long-lived assets. Such assets are reviewed quarterly for impairment indicators. If a triggering event has occurred, the assets are remeasured when the estimated fair value of the corresponding asset or asset group is less than the carrying value. The fair value measurements, in such instances, are based on significant unobservable inputs (Level 3). There were no significant impairments recorded during the fiscal year ended March 29, 2013.
	The carrying amounts of the Company’s financial instruments with short-term maturities are deemed to approximate their market values. The carrying amount of the Company’s long-term debt, excluding capital leases was $2,096 million and $2,119 million, and the estimated fair value was $2,270 million and $2,324 million, as of June 28, 2013, and March 29, 2013, respectively. The fair value of long-term debt is estimated based on the current interest rates offered to the Company for instruments with similar terms and remaining maturities and are classified as Level 2.									During fiscal 2012, as a result of annual and interim goodwill impairment assessments, goodwill was impaired with a charge of $2,745 million (see Note 9). The Company used the combination of the income and the market approach techniques to measure fair value of its reporting units, and a combination of the income, cost and market approach techniques to determine the fair value of the assets and liabilities comprising reporting units. The fair value adjustment to goodwill was computed as the difference between the fair value of the reporting unit and the fair value of underlying assets and liabilities. The unobservable inputs used to fair value the reporting units were based on Company-specific information such as revenue and cost growth rates, profit margins and discount rates. The unobservable inputs used to fair value the underlying assets and liabilities were also based on Company-specific information such as estimates of revenue and cost growth rates, profit margins, discount rates, cost estimates and guideline transactions data.
	The primary financial instruments other than derivatives (see Note 7) that potentially subject the Company to concentrations of credit risk are accounts receivable. The Company’s customer base includes Fortune 500 companies, the U.S. federal and other governments and other significant, well-known companies operating in North America, Europe and the Pacific Rim. Credit risk with respect to accounts receivable is minimized because of the nature and diversification of the Company’s customer base. Furthermore, the Company continuously reviews its accounts receivable and records provisions for doubtful accounts as needed.									Additionally, during fiscal 2012, due to performance issues on certain of its outsourcing contracts, the Company recorded impairment of primarily long-lived assets of $156 million. The Company used the income approach technique to fair value the assets. The unobservable inputs used were based on Company specific information and included, primarily, estimates of revenue and cost growth rates, profit margins and discount rates.
	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 June 28, 2013, the Company had $15 million of accounts receivable, $10 million of related allowance for doubtful accounts, and $1 million of other assets with customers involved in bankruptcy proceedings.									Financial Instruments
										The carrying amounts of the Company’s financial instruments with short-term maturities are deemed to approximate their market values. The carrying amount of the Company’s long-term debt, excluding capital leases and including mandatorily redeemable preferred stock outstanding, was $2,119 million and $1,073 million and the estimated fair value was $2,324 million and $1,190 million as of March 29, 2013, and March 30, 2012, respectively.

	As a large global organization, the Company faces exposure to adverse movements in foreign currency exchange rates. During the ordinary course of business, the Company enters into certain contracts denominated in foreign currency. Potential foreign currency exposures arising from these contracts are analyzed during the contract bidding process. The Company generally manages these transactions by incurring costs to service such contracts in the same currency in which revenue is received. Short-term contract financing requirements are met by borrowing in the same currency. By generally matching revenues, costs and borrowings to the same currency, the Company has been able to substantially mitigate foreign currency risk to earnings. However, as business practices evolve, the Company is increasing its use of offshore support and is therefore becoming more exposed to currency fluctuations.

However, as business practices evolve, the Company is increasing its use of offshore support and is therefore becoming more exposed to currency fluctuations.
	The Company established policies and procedures to manage the exposure to fluctuations in foreign currency by using short-term foreign currency forward and option contracts to hedge certain foreign currency assets and liabilities, including intercompany loans and certain revenues denominated in non-functional currencies. For accounting purposes, these foreign currency contracts are not designated as hedges, as defined under ASC 815, “Derivatives and Hedging,” and all changes in fair value are reported as part of other (income) expense. The Company uses these instruments as economic hedges and not for speculative or trading purposes.

	As a result of the use of derivative instruments, the Company is subject to counterparty credit risk. To mitigate this risk, the Company enters into forward and option contracts with several financial institutions and regularly reviews its credit exposure and the creditworthiness of the counterparties. As of June 28, 2013, there were seven counterparties with concentration of credit risk. The maximum amount of loss, based on gross fair value of the foreign currency derivative instruments that the Company could incur, is $7 million.

	Estimated amortization related to intangible assets, including amortization of contract cost premium, as of March 29, 2013, for fiscal 2014 through fiscal 2018, is as follows: $351 million, $292 million, $211 million, $158 million, and $112 million, respectively.
	Purchased and internally developed software, net of accumulated amortization, consisted of the following:
	(Amounts in millions)	March 29, 2013		March 30, 2012
	Purchased software	$	297	$	353
	Internally developed commercial software	304		293

	Amortization expense related to purchased software was $143 million, $149 million, and $135 million, for the years ended March 29, 2013, March 30, 2012, and April 1, 2011, respectively. Amortization expense related to internally developed commercial software was $53 million, $47 million, and $34 million, for the years ended March 29, 2013, March 30, 2012, and April 1, 2011, respectively. Amortization expense related to internally developed internal-use software was $2 million, $4 million, and $6 million, for the years ended March 29, 2013, March 30, 2012, and April 1, 2011, respectively.
	During fiscal 2012, the Company recorded $75 million as an impairment of its intangible assets, primarily due to performance issues on certain long-term outsourcing contracts within its GIS segment. The intangible assets impacted included primarily, software and capitalized transition costs. The Company used the income approach technique to fair value the assets. The unobservable inputs used were based on Company specific information and included, primarily, estimates of revenue and cost growth rates, profit margins and discount rates. The impairment was recorded as a part of cost of services.

	The following table summarizes the changes in the carrying amount of goodwill by segment for the three months ended June 28, 2013:

	Balance as of June 28, 2013, net	$	616		$	78		$	750		$	1,444
	* Both the gross goodwill and accumulated impairment losses amounts have been adjusted by $19 million, to reflect the fully impaired goodwill associated with the fiscal 2013 divested enterprise systems integration business.
	As described in Note 13, at the beginning of fiscal 2014, the Company changed its operating model, which resulted in changes to the Company's reportable segments. Concurrent with the change in the reportable segments, the Company reassigned goodwill to its reporting units, using a relative fair value allocation approach. As a result of this reassignment, $47 million of goodwill was reallocated from the former MSS segment to the new GBS segment. The reallocated goodwill is reflected in the goodwill balances as of March 29, 2013, noted above.
	The deductions in goodwill relate to classification of a portion of NPS' goodwill to assets held for sale in connection with the sale of ATD and the divestiture of GBS' flood insurance BPO business (see Notes 3 and 18). 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, and between annual tests 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.
	Due to the segment reorganization described above, the Company performed the first step of the goodwill impairment test for all reporting units as of the beginning of the first quarter of fiscal 2014. Based on the results of the first step of the impairment test, the Company concluded that the fair value of each reporting unit exceeded its carrying value and therefore the second step of the goodwill impairment test was not required.
	Due to the disposal of the flood insurance BPO business during May 2013, the Company performed an assessment to determine whether the remaining goodwill of GBS' Industry Software and Solutions (IS&S) reporting unit, which contained the divested business, might be impaired. The Company determined that no impairment existed. In addition, due to the classification of the ATD as discontinued operations during May 2013, CSC performed the first step of the goodwill impairment test for the remaining business of the NPS reporting unit. The fair value of the reporting unit exceeded its carrying value, and the second step of the goodwill impairment test was not required.
	At the end of the first quarter of fiscal 2014, the Company assessed whether there were events or change in circumstances that would more likely than not reduce the fair value of any of its reporting units below their carrying amounts. There were no such indicators for any of the reporting units with goodwill, and therefore, it was unnecessary to perform the first step of the two-step impairment testing process as of June 28, 2013. The fair values of all of our reporting units were substantially in excess of their carrying values based on the step one performed in conjunction with our first quarter fiscal 2014 goodwill reallocation and impairment testing. None of our reporting units were at risk of failing step one at that time.

														Effective at the beginning of fiscal 2014, the Company began operating under its new reportable segments, GBS, GIS and NPS (see Note 16). The following tables summarize the changes in the carrying amount of goodwill, by segment, for the years ended March 29, 2013, and March 30, 2012, respectively, assuming that the segment change occurred at the beginning of fiscal year 2012.

														The fiscal 2013 addition to goodwill of $25 million relates to an acquisition in the NPS segment (see Note 4). The reduction of $241 million relates to the divestiture of a business within the GBS segment (see Note 3). The foreign currency translation amount relates to the impact of currency movements on non-U.S. dollar denominated goodwill balances.
														The fiscal 2012 additions to goodwill of $476 million consisted of: 1) $475 million related to the acquisition of four new businesses, two within the GBS segment, 1 that was allocated between GBS and GIS segments, and one within the NPS segment; and 2) $1 million of contingent consideration paid upon the achievement of contractually-defined revenue target relating to a fiscal 2009 NPS acquisition (see Note 4).
														As noted in Note 1, the Company tests goodwill for impairment on an annual basis, as of the first day of the second fiscal quarter, and between annual tests 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.
														During the second quarter of fiscal 2013, the Company performed its annual impairment test of goodwill, choosing to bypass the initial qualitative assessment and proceeding directly to the first step of the impairment test for all reporting units, and concluded that no impairment had occurred.
														Due to the divestiture of the credit services business in the third quarter of fiscal 2013, which caused the allocation of $241 million of goodwill from the GBS-Industry Software & Solutions (GBS-IS&S) reporting unit to that disposed business, we assessed the goodwill remaining on the GBS-IS&S balance sheet for potential impairment. The Company performed the first step of the two-step of the goodwill impairment test and concluded that the goodwill remaining on the GBS-IS&S balance sheet, after allocation of goodwill to the divested business, was not impaired.
														During the fourth quarter of fiscal 2013, the Company assessed whether there were events or change in circumstances that would more likely than not reduce the fair value of any of its reporting units below their carrying amounts. The Company considered, among other factors, any significant changes in the Company's fiscal 2013 forecast since the annual impairment test was performed, the outlook for the Company's business and industry, including the impact of sequestration by the U.S. federal government, the Company's market capitalization, and the current economic environment and outlook. Based on that assessment, the Company determined that there have been no events or changes in circumstances that would more likely than not reduce the fair value of any of its reporting units below their carrying amounts, and, as a result, it was unnecessary to perform the first step of the two-step impairment testing process as of March 29, 2013. Any adverse changes in the business climate or in CSC's operating results could result in the need to perform additional impairment analyses of goodwill prior to the next annual test, which may result in impairment charges.
														During fiscal 2012, the Company initiated its annual goodwill analysis in the second quarter and concluded that fair value was below carrying value for three reporting units: GIS, GBS-Consulting and GBS-IS&S. Management believed that the decline in the estimated fair values of these reporting units during the second quarter was a result of a number of factors, including: the significant decline in the Company’s overall stock price over the first six months of fiscal 2012; an overall decline in the broader stock market which resulted in reduced performance metric multiples at comparable public companies; uncertainty caused by concerns about the ongoing SEC investigation into reported errors and irregularities; concerns about the Company’s growth prospects in light of operational issues at its GIS reporting unit; uncertainty over the continuation of the Company’s NHS contract in light of comments made by government officials in the U.K.; and government budget pressures on customers worldwide. Lower than forecast operating performance also impacted the reporting units’ fair value calculations. Prior to the second quarter of fiscal 2012, the Company's stock price declines were considered temporary. In addition, an evaluation of historical and forecast operating results did not indicate it was more likely than not that the fair value of any reporting unit had fallen below carrying value, and therefore no interim goodwill impairment test was warranted prior to the second quarter.
														At the end of the second quarter and subsequent to the date of the annual goodwill impairment test, the Company determined that sufficient indicators existed to require performance of an additional interim goodwill impairment analysis as of September 30, 2011. These indicators included: a further significant and sustained decline in CSC’s stock price which resulted in a market capitalization, adjusted for control premium, decreasing to an amount less than book value and remaining there for some time; further decreases in the performance metric multiples of comparable public companies, driving the market approach valuations lower; and additional evidence of certain reporting units’ performance which fell short of forecasts used in the annual market- and income-based tests. In this interim goodwill impairment test, the GBS-Consulting reporting unit again failed step one of the two-step test.
														During the process of conducting the second step of the annual goodwill impairment tests, the Company identified significant previously unrecognized intangible assets, primarily relating to customer relationships and technology. The unrecognized intangible assets, estimated at approximately $1.3 billion, were predominantly attributable to unrecognized customer relationship assets in the GIS reporting unit and were driven by the Company’s high customer retention rates in this business. The combination of these previously unrecognized intangible assets and other unrecognized fair value changes to the carrying values of other assets and liabilities, together with the lower reporting unit fair values calculated in step one, resulted in an implied fair value of goodwill substantially below the carrying value of goodwill for the GIS, GBS-Consulting and GBS-IS&S reporting units. As a result, the Company recorded its best estimate of the goodwill impairment charge of $2,685 million, of which $2,074 million related to the GIS reporting unit, $453 million related to the GBS-Consulting reporting unit, and $158 million related to the GBS-IS&S reporting unit.
														The September 30, 2011 interim goodwill test indicated that the fair value of the GBS-IS&S reporting unit passed step one (after the impairment charges discussed above) but was not considered to be substantially in excess of carrying value, and as noted above had a remaining goodwill balance, after impairments recorded in the second quarter, of $60 million at September 30, 2011.
														During the third quarter of fiscal 2012, the Company completed all analyses related to its annual and second quarter interim goodwill impairment tests and reduced the impairment loss recorded in the second quarter by $3 million. The entire adjustment was in the GBS-IS&S reporting unit, and resulted from finalizing tax estimates and customer/technology asset fair values. Thus, the total second quarter goodwill impairment loss was $2,682 million, with $3 million of it recorded in the third quarter.
														At the end of the third quarter of fiscal 2012, the Company assessed whether there were any events or circumstances that would more likely than not reduce the fair value of a reporting unit below its carrying value. The Company concluded that such indicators were present for its GBS-IS&S reporting unit due to the loss of a significant customer, the failure to win some major bids for new business, developments on the NHS contract, and reduction in forecasted earnings was considered a triggering event for an interim goodwill impairment test (see Note 18). There were no triggering events for the remaining reporting units with goodwill.
														In conducting step one of the goodwill impairment test for the GBS-IS&S reporting unit in the third quarter of fiscal 2012, the factors stated above resulted in a reassessment of forecasted cash flow assumptions under an income approach, as well as a revised valuation using a market-multiples fair value approach, which resulted in the weighted-average fair value of the reporting unit being lower than its carrying value. This required the Company to perform the second step of the two-step test process, as noted below.
														During the process of conducting step two of the interim goodwill impairment test for GBS-IS&S, the Company estimated the fair value of its tangible assets and the unrecognized intangible assets, primarily customer relationship and technology assets, and recorded an impairment charge of $63 million.
														The Company tested its long-lived assets for impairment in conjunction with the annual and the second and third quarter interim goodwill impairment tests and concluded that these assets were not impaired.
														At the end of the fourth quarter of 2012, the Company assessed whether there were events or change in circumstances that would more likely than not reduce the fair value of any of its reporting units below their carrying amounts. There were no such indicators for any of the reporting units with goodwill, and therefore, an interim goodwill test was not required.

	The Company's effective tax rate (ETR) was 31.3% and 47.5% for the first quarters ended June 28, 2013 and June 29, 2012, respectively. The primary drivers of the ETR for the first quarters ended June 28, 2013 and June 29, 2012, respectively, were the change in valuation allowances in non-U.S. jurisdictions and the global mix and amount of income. For the tax impact of discontinued operations, see Note 3.	The sources of (loss) income from continuing operations, before income taxes, classified between domestic entities and those entities domiciled outside of the United States, are as follows:
	There were no material changes to uncertain tax positions in the first quarter of fiscal 2014 compared to the fiscal 2013 year-end.

	The IRS is examining the Company's federal income tax returns for fiscal years 2008 through 2010. During the first quarter of fiscal 2014, the IRS indicated they need additional time to complete the examination. Therefore, the Company now expects to reach a resolution during fiscal year 2015. In addition, the statute of limitation for these fiscal years is currently expected to close during fiscal year 2015. The significant item subject to examination primarily relates to foreign exchange losses. In addition, the Company may settle certain other tax examinations, have lapses in statutes of 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 through payment. It is reasonably possible that during the next twelve months the Company's liability for uncertain tax positions may change by a significant amount. The Company believes the outcomes which are reasonably possible within the next twelve months may result in a reduction in the liability for uncertain tax positions of up to $9 million, excluding interest, penalties, and tax carryforwards.

		In fiscal 2013, the ETR was primarily driven by:
		•	The Company executed an internal restructuring whereby a significant operating subsidiary was recapitalized. Certain securities issued pursuant to the recapitalization were subsequently sold to a third party. The sale resulted in the recognition of a capital loss of approximately $640 million, which reduced tax expense and the ETR by $248 million and 55.2%, respectively.
		•	A valuation allowance recorded for certain of the Company's German subsidiaries related to net operating losses and other net deferred tax assets. The impact to tax expense and the ETR was an increase of $77 million and 17.2%, respectively.
		•	An increase in the valuation allowance determined on a tax jurisdictional basis due to several factors including: (i) a shift in the global mix of income which increased tax expense and the ETR by $27.6 million and 6.1%, respectively (ii) capital gains from the sale of certain other assets which decreased tax expense and the ETR by $11.5 million and 2.6%, respectively and (iii) state capital losses and credits not expected to be fully utilized within the carryforward period which increased tax expense and the ETR by $29.6 million and 6.6%, respectively.
		•	Local losses on investment write-downs in Luxembourg (i) increased the valuation allowance and the ETR by $240.5 million and 53.5%, respectively, and (ii) decreased the foreign rate differential and ETR by $240.5 million and by 53.5%, respectively.
		For the tax impact of discontinued operations, see Note 3.

	Income tax related assets are included in the accompanying balance sheet as follows:
	•	Prepaid expenses and other current assets include the current portion of deferred tax assets of $24 million and $19 million as of March 29, 2013 and March 30, 2012, respectively.
	•	Receivables include income taxes receivable of $239 million and $98 million as of March 29, 2013 and March 30, 2012, respectively, and the current portion of the receivable for uncertain tax positions of $8 million and $0 million as of March 29, 2013 and March 30, 2012, respectively.
	•	Other assets include non-current deferred tax assets of $184 million and $272 million as of March 29, 2013 and March 30, 2012, respectively, and non-current income taxes receivable and prepaid taxes of $70 million and $154 million as of March 29, 2013 and March 30, 2012, respectively.
	Income tax related liabilities are included in the accompanying balance sheet as follows:
	•	Income taxes payable and deferred income taxes consist of the current portion of deferred tax liabilities of $0 million and $46 million as of March 29, 2013 and March 30, 2012, respectively, the current portion of income taxes payable of $41 million and $11 million as of March 29, 2013 and March 30, 2012 respectively.
	•	Income tax liabilities and deferred income taxes included in non-current liabilities consist of non-current liability for uncertain tax positions of $270 million and $257 million as of March 29, 2013 and March 30, 2012, respectively, and the non-current portion of deferred tax liabilities of $231 million and $99 million as of March 29, 2013 and March 30, 2012, respectively, the non-current portion of income taxes payable of $0 million and $1 million as of March 29, 2013 and March 30, 2012, respectively.
	In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized and adjusts the valuation allowance accordingly. In determining whether the deferred tax assets are realizable, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, taxable income in prior carryback years, projected future taxable income, tax planning strategies and recent financial operations. Valuation allowances are evaluated periodically and will be subject to change in each future reporting period as a result of changes in one or more of these factors. The change in the valuation allowance was $347 million in fiscal year 2013. This change is primarily due to the following:
	•	a full valuation allowance recorded in Germany for certain subsidiaries due to expected cumulative losses;
	•	a decrease in the valuation allowance in the U.K. related to current year income;
	•	an increase in the valuation allowance in Luxembourg due to local losses on investment write-downs; and
	•	a valuation allowance recorded against state capital loss carryforwards.
	The Company has available foreign net operating loss (NOL) carryforwards of $3,661 million and $3,272 million, federal NOL carryforwards of $5 million and $14 million, and state NOL carryforwards of $782 million and $467 million as of March 29, 2013 and March 30, 2012, respectively. The Company has foreign capital loss carryforwards of $45 million and $0 million as of March 29, 2013 and March 30, 2012, respectively. The Company also has state credit carryforwards of $67 million and $69 million and state capital loss carryforwards of $411 million and $0 million as of March 29, 2013 and March 30, 2012, respectively. The foreign NOL carryforwards as of March 29, 2013 can be carried over indefinitely, except for $122 million which expire at various dates through 2021. The federal NOL carryforwards as of March 29, 2013 expire at various dates through 2032. The state NOL and credit carryforwards as of March 29, 2013 expire at various dates through 2033. The state capital loss carryforwards as of March 29, 2013 expire in 2018.
	The Company is currently the beneficiary of tax holiday incentives in India, most of which expired in fiscal year 2011. The remaining tax holiday incentives in India will expire through 2026. As a result of the tax holiday incentives, the Company’s tax expense was reduced by approximately $3 million, $1 million, and $13 million, during fiscal years 2013, 2012, and 2011, respectively. The per share effects were $0.02, $0.01, and $0.08, for fiscal years 2013, 2012, and 2011, respectively.
	In general, it is the practice and intention of the Company to reinvest the earnings of its non-U.S. subsidiaries in those operations. As of March 29, 2013, the Company has not made a provision for U.S. income tax or additional foreign withholding taxes with respect to accumulated taxable earnings of foreign subsidiaries where the foreign investment of such earnings is essentially permanent in duration. Generally, such amounts would become subject to U.S. taxation upon the remittance of dividends and under certain other circumstances. The cumulative undistributed positive earnings of the Company's foreign subsidiaries were approximately $2,977 million as of March 29, 2013. It is not practicable to estimate the tax cost of repatriating the cumulative undistributed taxable earnings of these foreign subsidiaries to the United States.
	The Company accounts for income tax uncertainties in accordance with ASC 740-10, which prescribes a recognition threshold and measurement criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. ASC 740 also provides guidance on the accounting for and disclosure of liabilities for uncertain tax positions, interest and penalties.
	As of March 29, 2013, the Company’s liability for uncertain tax positions was $262 million, including interest of $38 million, penalties of $17 million, and net of tax attributes of $32 million. As of March 30, 2012, the Company’s liability for uncertain tax positions was $257 million, including interest of $31 million, penalties of $15 million, and net of tax attributes of $76 million.
	The following table summarizes the activity related to the Company’s uncertain tax positions (excluding interest and penalties and related tax attributes):

	Balance at End of Fiscal Year		$	241			$	287			$	426
	The Company’s liability for uncertain tax positions at March 29, 2013, March 30, 2012, and April 1, 2011, includes $148 million, $155 million, and $266 million, respectively, related to amounts that, if recognized, would affect the effective tax rate (excluding related interest and penalties).
	The Company recognizes interest accrued related to uncertain tax positions and penalties as a component of income tax expense. During the year ended March 29, 2013, the Company accrued interest expense of $7 million ($5 million net of tax) and accrued penalties of $2 million, and as of March 29, 2013, has recognized a liability for interest of $38 million ($28 million net of tax) and penalties of $17 million. During the year ended March 30, 2012, the Company had a net reduction of interest of $56 million ($36 million net of tax) and had a net reduction of penalties of $14 million, and as of March 30, 2012, recognized a liability for interest of $31 million ($23 million net of tax) and penalties of $15 million. During the year ended April 1, 2011, the Company accrued interest expense of $3 million ($2 million net of tax) and accrued penalties of $2 million, and as of April 1, 2011, recognized a liability for interest of $88 million ($58 million net of tax) and penalties of $29 million.
	Tax Examination Status:
	The Company is currently under examination in several tax jurisdictions. A summary of the tax years that remain subject to examination in certain of the Company’s major tax jurisdictions are:
	Jurisdiction:		Tax Years that Remain Subject to Examination
			(Fiscal Year Ending):
	United States – Federal		2008 and forward
	United States – Various States		2001 and forward
	Australia		2009 and forward
	Canada		2006 and forward
	Denmark		2007 and forward
	France		2009 and forward
	Germany		2006 and forward
	India		2007 and forward
	United Kingdom		2010 and forward
	It is reasonably possible that during the next twelve 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 year 2008 through 2010, and the Company expects to reach a settlement during fiscal year 2014. The significant items subject to examination primarily include foreign income inclusion under subpart F and related foreign tax credits. In addition, the Company may settle certain other tax examinations, have lapses in statutes 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 twelve months may result in a reduction in liability for uncertain tax positions of up to $92 million, excluding interest and penalties.

	Term notes and term loan credit facility
	On September 18, 2012, the Company issued $700 million of senior unsecured and unsubordinated notes (new term notes) comprised of $350 million of 2.50% Senior Notes due September 15, 2015 and $350 million of 4.45% Senior Notes due September 15, 2022. The new term notes were recorded net of debt discount of $1 million. The Company also incurred deferred debt issuance costs of $5 million, which along with the debt discount will be amortized over the respective terms of the new term notes using the effective interest method. The new term notes are senior unsecured and unsubordinated obligations and rank equally with all other existing and future senior unsecured and unsubordinated indebtedness, including any borrowings under the existing $1.5 billion Credit Facility (discussed below), and senior to all future subordinated debt. Interest is payable semi-annually on September 15 and March 15 beginning March 15, 2013. The proceeds from the new term notes were used to redeem a portion of the 5.50% term notes due March 2013 and the 5.00% term notes due February 2013, as described below.
	In addition, on September 18, 2012, the Company entered into a four-year, unsecured, delayed-draw $250 million term loan maturing on September 18, 2016. Under the term loan, the Company has an option to request an increase in the commitment up to a maximum amount of $350 million. Interest on borrowings under the new facility is based on prime rate or LIBOR plus a daily margin, and is payable quarterly. Quarterly principal repayments of 2.5% of borrowings commence December 31, 2013. Costs associated with establishing the term loan of $1 million have been deferred and will be amortized over the term of the agreement. On October 17, 2012, the Company borrowed $250 million under the term loan and used the proceeds to redeem a portion of the 5.50% and 5.00% term notes due in the fourth quarter of 2013, as described below.
	On September 12, 2012, the Company delivered a notice of early redemption with respect to the Company’s outstanding $700 million 5.50% Senior Notes due March 2013 and $300 million 5.00% Senior Notes due February 2013. On October 19, 2012, the Company used the proceeds received from the issuance of new term notes and the $250 million drawn from the term loan credit facility to fund the early redemption of the 5.00% and 5.50% term notes due February 2013 and March 2013, respectively, resulting in the recognition of a $19 million loss recorded to interest expense.
	Both the new term notes and the new term loan credit facility agreement contain representations, warranties, and covenants customary for arrangements of these types, as well as customary events of default, including a cross-default to payment defaults on principal payments aggregating $125 million or to other events if the effect is to accelerate or permit acceleration of such debt.
	Both the term loan credit facility and the $1.5 billion Credit Facility (see below) require the Company to: (1) maintain a minimum interest coverage ratio of consolidated Earnings Before Interest, Taxes, Depreciation and Amortization adjusted for other non-cash charges as defined by the credit agreement (EBITDA), to consolidated interest expense for the period of four consecutive fiscal quarters ending on or immediately prior to such period not to be less than 3.00 to 1.00; and (2) not permit at the end of any quarterly financial reporting period the ratio of consolidated total debt to consolidated EBITDA for the period of four consecutive fiscal quarters ending on or immediately prior to such date, to exceed 3.00 to 1.00. The Company was in compliance with these financial covenants as of March 29, 2013 and March 30, 2012.
	Mandatorily redeemable preferred stock and note payable of a consolidated subsidiary
	Mandatorily redeemable preferred stock
	In March 2013, CSC entered into a financing agreement with a bank involving the sale of the Company's interest in mandatorily redeemable preferred stock (the preferred stock) of one of its wholly-owned subsidiaries (the Subsidiary). Such preferred stock is mandatorily redeemable on the tenth anniversary of its issuance (in 2023) but can be optionally redeemed by the Subsidiary at any time after the fifth anniversary of issuance. Therefore, the preferred stock was accounted for as a liability and is presented as long-term debt within the consolidated balance sheet.
	The preferred stock has a stated value of $63 million (the initial liquidation preference) and was recorded at its issue date fair value of $59 million. The difference between the initial fair value and the stated value will be accreted over the term of the preferred stock. The Company incurred debt issuance costs of $1 million associated with the issuance of the preferred stock. These costs have been deferred and will be amortized over ten years using the effective interest method.
	The preferred stock requires payment of cumulative preferred dividends at 3.48% per annum for the first five years. In addition, the holder of the preferred stock has a remarketing option, exercisable by the holder after five years from initial issuance, that if exercised, requires the assistance of the Subsidiary to remarket the Series A preferred stock, which under certain circumstances, may result in changes to the thereafter dividend rate in order to successfully remarket the securities. Dividends are payable on a quarterly basis and any unpaid dividends are subject to an incremental interest rate margin of 2.50%. The preferred shares also participate at 3.80% in 1) dividends paid on the Subsidiary's common stock and in 2) any future appreciation (as defined in the agreement) of the Subsidiary's common stock equity value (variable redemption premium). The liquidation preference of the preferred stock is the sum of the stated value of the shares, accrued but unpaid dividends, and any unpaid variable redemption premium.
	Note payable
	Concurrent with the financing agreement mentioned above, the Company entered into a separate credit agreement with a bank to sell the Company's interest in a five-year note receivable due 2018 issued by the Subsidiary for cash consideration of £41 million ($62 million as of March 29, 2013). The Company incurred $1 million of debt issuance costs associated with the note payable. These costs have been deferred and will be amortized over five years using the effective interest method.
	The note bears interest in British pounds at a variable rate based on LIBOR and is payable on a quarterly basis. Although the note is due in five years, the Subsidiary has the option to repay the principal amount of the note plus any unpaid accrued interest beginning upon its third anniversary from issuance. As part of the sale of the note to the bank, the Company became a guarantor of the Subsidiary's note payable. The financing agreement and the credit agreement require the Subsidiary to retain a minimum amount of assets. The Company and the Subsidiary were in compliance with all financial covenants at March 29, 2013.
	Capital lease liabilities
	Capitalized lease liabilities represent obligations due under capital leases for the use of computers and other equipment. The gross amount of assets recorded under capital leases was $1,095 million with accumulated amortization of $465 million, as of March 29, 2013, and $940 million with accumulated amortization of $341 million, as of March 30, 2012.
	Borrowings for assets acquired under long-term financing
	Certain asset purchases under outsourcing contracts were financed by borrowings from customers. These borrowings carry a rate of interest from 0.0% to 4.9% and will mature over the next five years. Gross amounts of assets purchased under long-term financings included $69 million and $44 million in property and equipment, $54 million and $45 million in software, $90 million and $86 million in outsourcing contract costs and $10 million and $10 million in other intangible assets as of March 29, 2013 and March 30, 2012, respectively.
	Other borrowings
	Several foreign subsidiaries of the Company had no borrowings outstanding, as of March 29, 2013, and $43 million of borrowings outstanding, as of March 30, 2012, under uncommitted lines of credit with certain foreign banks. CSC has provided parent guarantees for these short-term lines of credit which carry no commitment fees or significant covenants. In addition, the Company had $5 million and $43 million of other borrowings outstanding as of March 29, 2013 and March 30, 2012, respectively, consisting of other interest bearing debt and notes payable.
	Commercial paper
	The Company typically issues commercial paper with average maturities of one to three months. The commercial paper is backed by the $1.5 billion Credit Facility discussed below. As of both March 29, 2013 and March 30, 2012, the Company had no borrowings outstanding against commercial paper.
	Credit facility
	On March 18, 2011, the Company entered into a committed, unsecured line of credit for $1.5 billion (Credit Facility) that expires on March 18, 2015. The Credit Facility bears a variable rate of interest. The Company can elect to borrow at a prime rate, as published by the Bank of America, plus a margin or at a one, two, three, or six month LIBOR plus a margin. The margin varies with the credit ratings of the Company. As of both March 29, 2013 and March 30, 2012, the Company had no amounts outstanding under this Credit Facility.
	Expected maturities of long-term debt, including borrowings for asset financing but excluding future minimum capital lease payments, for years subsequent to March 29, 2013, are as follows:
	Fiscal Year	Amount (in millions)
	2014	$	52

	The Company and its subsidiaries offer a number of pension and postretirement benefits, life insurance benefits, deferred compensation, and other plans. The components of net periodic pension cost for U.S. and non-U.S. pension plans included the following components:													The Company and its subsidiaries offer a number of pension and postretirement benefits, life insurance benefits, deferred compensation, and other plans, as described below. All plans are accounted for using the guidance of ASC 710 "Compensation - General" and ASC 715 “Compensation—Retirement Benefits” and are measured as of the end of the fiscal year.
														Contributory, defined benefit pension plans have been generally available to U.S. and U.K. employees. However, the largest U.S. and U.K. defined benefit plans were frozen for most participants in prior years. Certain non-U.S. employees are enrolled in defined benefit pension plans in the country of domicile. In addition, the Company has two supplemental executive retirement plans (SERP), which are non-qualified, noncontributory pension plans. The Company provides subsidized healthcare and life insurance retirement benefits for certain U.S. employees and retirees, generally for those employed prior to August 1992, as well as healthcare, dental and life insurance benefits for certain non-U.S. employees. A significant number of employees outside the U.S. are covered by government sponsored programs at no direct cost to the Company other than related payroll taxes.
		Quarter Ended												CSC utilizes actuarial methods to recognize the expense for pension and other postretirement benefit plans. Inherent in the application of these actuarial methods are key assumptions, including, but not limited to, discount rates and expected long-term rates of return on plan assets. Changes in the related pension and other postretirement benefit costs may occur in the future due to changes in the underlying assumptions, changes in the number and composition of plan participants and changes in the level of benefits provided.

	(Amounts in millions)	June 28, 2013			June 29, 2012			June 28, 2013			June 29, 2012			As discussed in Note 17, the Company initiated restructuring activities in both fiscal 2013 and 2012. The Fiscal 2012 Plan restructuring resulted in contractual termination benefit charges for some employees participating in a certain U.K. pension plan. During fiscal 2012, the Company recognized $20 million in expected contractual termination benefits which are reflected in the projected benefit obligation at the end of fiscal 2012 and recognized as expense in net periodic pension cost during fiscal 2012. During fiscal 2013, the projected benefit obligation and the net periodic pension cost reflect adjustments to the original estimates for actual contractual termination benefits paid in relation to the Fiscal 2012 Plan in the amount of $(3) million. Additionally, the Fiscal 2013 Plan restructuring resulted in expected contractual termination benefits for some employees participating in this same U.K. pension plan. During fiscal 2013, the Company recognized $23 million in expected contractual termination benefits which are reflected in the projected benefit obligation at the end of fiscal 2013 and recognized as expense in net periodic pension cost during fiscal 2013.
	Service cost	$	2		$	3		$	7		$	8
														Effective July 1, 2012 a certain Norway pension plan was amended to change the index used to benchmark pension payment increases. The plan was remeasured at July 1, 2012 resulting in a reduction to the projected benefit obligation of $28 million, improving the plan's funded status. The plan's fiscal 2013 expense was also remeasured for the remaining 9 months of the fiscal year using a discount rate of 4%.
	Interest cost	38			40			30			31
														On December 31, 2012, the Company made a discretionary cash contribution of $400 million to its largest U.S. pension plan resulting in a remeasurement of the plan. The effects of this remeasurement were recorded during the fourth quarter of fiscal 2013 and resulted in a reduction of net periodic pension cost of $7.6 million for fiscal 2013 and additional plan liabilities of $379 million using a new discount rate of 4%.

	Contractual termination benefits	—			—			1			5			Effective December 31, 2012, a second U.S. pension plan was remeasured as a result of a plan amendment which ceased benefit accruals on or after January 5, 2013. The effects of this remeasurement were recorded during the fourth quarter of fiscal 2013 and resulted in a reduction of net periodic pension cost of $1.1 million for fiscal 2013 and additional plan liabilities of $3 million using a new discount rate of 4.2%
	Net periodic pension cost	$	—		$	14		$	7		$	18		On April 7, 2010, the Company announced an action to discontinue the accrual of future benefits for certain U.K. pension plans, effective July 1, 2010. As a result of this plan amendment, the Company recognized a curtailment loss of $0.4 million in the fourth quarter of fiscal 2010. In addition, the Company remeasured the amended U.K. plans’ pension expense for fiscal 2011 to reflect (a) a new discount rate of 5.6%, (b) the year-to-date increase in plan assets, and (c) the change in amortization basis to the expected average remaining life of plan participants. The U.K. plans’ discount rate was derived from a published rate: Markit iBoxx GBP Corporates AA 15+ Years Index. This remeasurement resulted in a $75 million reduction to the pension benefit obligation.
														In response to the passage of the Patient Protection and Affordable Care Act of 2010 (PPACA), a number of changes were made to the underlying healthcare coverage offered to certain US retirees. In conjunction with those changes, the Company established limits on the level of employer subsidy it will provide to some retirees. The plans were amended and the impact of these changes is first reflected on April 1, 2011. In addition, although many administrative provisions of PPACA have not yet been promulgated by regulatory agencies, CSC included its best estimate of their financial impact into the benefit obligation for its U.S. postretirement benefit plans as of March 30, 2012, and the impact on fiscal 2012’s net periodic benefit cost was immaterial. In 2012, the retiree medical plans were further amended to allow Medicare Part D subsidies from 2012 and beyond to be collected by the healthcare provider. This subsequent change is reflected as of March 30, 2012 and the impact on fiscal 2012's net periodic benefit cost was immaterial.
	The Company contributed $28 million to the defined benefit pension plans during the quarter ended June 28, 2013. In aggregate, the Company expects to contribute approximately $121 million during fiscal 2014.

													No plan assets are expected to be returned to the Company in the next fiscal year.
													Retirement Plan Asset Strategy
													The Company’s investment goals and risk management strategy for plan assets takes into account a number of factors, including the time horizon of the pension plans’ obligations. Plan assets are invested in various asset classes that are expected to produce a sufficient level of diversification and a reasonable amount of investment return over the long term. Sufficient liquidity is maintained to meet benefit obligations as they become due. Third party investment managers are employed to invest assets in both passively-indexed and actively-managed strategies. Equities are primarily invested broadly in domestic and foreign companies across market capitalizations and industries. Fixed income securities are invested broadly, primarily in government treasury, corporate credit, mortgage backed and asset backed investments.
													Risks include, but are not limited to, longevity risk, inflation risk, and the risk of other changes in market conditions that reduce the value of plan assets. Also, a decline in the yield of high quality corporate bonds may adversely affect discount rates resulting in an increase in the pension and other post retirement obligations. These risks, among others, could cause the plans’ funded status to deteriorate, increasing reliance on Company contributions. Generally, derivatives are permitted although their current use is limited. They are primarily used in the U.S. pension trust fixed income portfolios for duration and interest rate risk management and equity portfolios to gain market exposure, and are expected to be used in the U.K. pension schemes for inflation risk management. The Company also has investments in insurance contracts to pay plan benefits in certain countries.
													For the U.S. pension trust, an allocation range by asset class is developed. The allocation had a significant weighting to equity investments in part due to the relatively long duration of the plans’ obligations. For the majority of the fiscal year, the allocation range for the U.S. pension trust was 49% – 66% equities, 34% – 44% fixed income securities and 0% – 10% cash and other investments. Asset allocations are monitored closely and investment reviews are conducted regularly. The Company consults with internal and external advisors regarding asset strategy and on March 21, 2013 adopted an allocation range for the U.S. pension trust of 37% - 66% equities, 29% - 44% fixed income securities, 0% - 25% alternative investments, and 0% - 10% cash and other investments. The alternative investments allocation may include, but is not limited to, hedge funds, real estate, commodities, private equity and infrastructure investments.
													For the U.K. pension schemes, the Company's second largest pension plans by assets and projected liabilities, a target allocation by asset class is developed. The allocation had a significant weighting to equity investments in part due to the relatively long duration of the plans' obligations. For the majority of the fiscal year the allocation targets for the U.K. pension schemes were 40% equities, 31% fixed income securities, and 29% indexed-Gilts. Asset allocations are monitored closely by the schemes' trustees and investment reviews are conducted regularly.
													Retirement Plan Asset Valuation Techniques
													Cash equivalents are primarily short term money market commingled funds that are categorized as Level 2, except for funds that have quoted prices in active markets, which are classified as Level 1. They are valued at cost plus accrued interest which approximates fair value.
													Fixed income separate accounts are categorized as Level 2. These investments are generally priced using model-based pricing methods that use observable market data as inputs. Broker dealer bids or quotes of securities with similar characteristics may also be used.
													Domestic and global equity separate accounts are categorized as Level 1 if the securities trade on national or international exchanges and are valued at their last reported closing price.
													Insurance contracts purchased to cover benefits payable to retirees are valued using the assumptions used to value the projected benefit obligation. Most of the plans' insurance contracts are categorized as level 2 while one plan has a level 3 insurance contract.
													The fair value of our pension plan assets and postretirement benefit plans by investment category and the corresponding level within the fair value hierarchy as of March 29, 2013 are as follows:

													Return on Assets
													In the U.S., the Company uses a “building block” approach to compute the expected long-term rate of return using major asset classes expected in the plan. Starting with long run projected bond yields, an equity risk premium is added to estimate the equity long-term rate of return. Consideration is also given to the extent active management is employed in each asset class. A single expected long-term rate of return on plan assets is then calculated by weighting each asset class. Historical returns and peer data were also reviewed
													Retirement Plan Discount Rate
													The U.S. discount rate assumption is prepared with a two step process; the first step discounts the stream of expected annual benefit payments using high-quality corporate bond yields. In step two, the sum of each year’s discounted benefit payments are used to determine a single equivalent discount rate. In fiscal 2013, the discount rates for the U.S. pension and other postretirement plans were developed using a single yield curve, the Aon Hewitt AA Only Above Median Curve. This yield curve is a hypothetical AA or greater yield curve represented by a series of annualized individual spot discount rates going out 99 years. This curve provides a more transparent view to the underlying bonds and is available daily which provides for a discount rate to be calculated specific to the Company's fiscal year end. For years prior to fiscal 2013, the U.S. discount rates were determined using an average of two nationally recognized independent third party yield curves.
													In fiscal 2012 the UK pension plans began using the AA Corporate Bond Mercer Pension Discount Yield Curve to set the discount rate. This yield curve approach determines a single equivalent discount rate from a curve based on market data using sample scheme cash flow data as a proxy to scheme specific liability cash flows. The benefits of the Mercer Pension Discount Yield Curve over the iBoxx GBP Corporates AA +15 index is that it provides the flexibility to use cash flow data over the average duration of the pension scheme's liabilities rather than over a set time period of 15 years. For years prior to fiscal 2012, the U.K. discount rate assumption was set by reference to the yield on the iBoxx GBP AA rated +15 years corporate bond index with an appropriate adjustment for duration if necessary after considering yield curve models and conditions in credit markets.
													Other Benefit Plans
													The Company sponsors several defined contribution plans for substantially all U.S. employees and certain foreign employees. The plans allow employees to contribute a portion of their earnings in accordance with specified guidelines. At March 29, 2013, plan assets included 10,730,413 shares of the Company’s common stock. During fiscal 2013, fiscal 2012, and fiscal 2011, the Company contributed $213 million, $223 million, and $207 million, respectively.
													Pursuant to collective bargaining agreements, the Company makes contributions, generally at a stated hourly rate, to various multi-employer pension funds on behalf of its union-represented employees. All of these plans are within the Company's NPS segment. None of the contributions by the Company are individually significant to the multi-employer plans nor do they have a material impact on the Company's financial statements. The risks of participating in these multi-employer plans are different from single-employer plans. If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. The Company's contributions for fiscal years 2013, 2012, and 2011 were $11 million, $11 million, and $10 million, respectively.
													Effective August 14, 1995, the Company adopted the Computer Sciences Corporation Deferred Compensation Plan (the Plan). The Plan consists of two separate plans, one for the benefit of key executives and one for the benefit of non-employee directors. Pursuant to the Plan, certain management and highly compensated employees are eligible to defer all or a portion of their regular salary that exceeds the limitation set forth in Internal Revenue Section 401(a)(17) and all or a portion of their incentive compensation, and non-employee directors are eligible to defer up to 100% of their compensation. Each plan participant is fully vested in all deferred compensation and earnings credited to his or her account. The liability, which is included in “Other long-term liabilities” under the Plan, amounted to $125 million as of March 29, 2013 and $129 million as of March 30, 2012. The Company’s expense under the Plan totaled $8 million, $8 million, and $8 million, for fiscal 2013, fiscal 2012, and fiscal 2011, respectively.

												The Company has three stock incentive plans which 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 awards and the settlement of restricted stock units (RSUs). There were no restricted stock awards outstanding in fiscal years 2013, 2012 and 2011. As of March 29, 2013, 11,977,359 shares of CSC common stock were available for the grant of future stock options, restricted stock or other stock-based incentives to employees.

	RSUs consist of equity awards with the right to receive one share of common stock of the Company issued at a price of $0. Upon the settlement date, RSUs are settled in shares of CSC common stock and dividend equivalents. If, prior to the vesting of the RSU in full, the employee's status as a full-time employee is terminated, then the RSU is automatically canceled on the employment termination date and any unvested shares are forfeited.
														15,140,567							10,694,088
	The Company grants RSUs with service and performance-based vesting terms. Service-based RSUs, generally vest over periods of three to five years. The number of performance-based RSUs that ultimately vest is dependent upon the Company's achievement of certain specified performance criteria over a three-year period. Awards are settled for shares of CSC common stock and dividend equivalents upon the filing with the SEC of the Annual Report on Form 10-K for the last fiscal year of the performance period if the specified performance criteria is met. In fiscal 2013, performance-based RSU awards granted include the potential for accelerated vesting of 25% of the shares granted after the first and second fiscal years if certain company performance targets are met early. Compensation expense during the performance period is estimated at each reporting date using management's expectation of the probable achievement of the specified performance criteria and is adjusted to the extent the expected achievement changes. In the first quarter of fiscal 2014, shares were released due to meeting the company performance targets in fiscal year 2013. The probable achievement was also increased to the maximum payout based on management's expectation of meeting the performance criteria resulting in additional expense recognized as previously discussed. In the table below, such awards are reflected at the number of shares to be settled upon achievement of target performance measures.
	During the three months ended June 28, 2013, certain executives were awarded service-based RSUs for which the shares are redeemable over the ten anniversaries following the executive’s separation from service as a full-time employee, provided the executive complies with certain non-competition covenants during the ten-year period following the executives separation of service. For the certain executives who joined the company in fiscal year 2013 and after, the awards vest at age 62, or 50% of the award partially vests at age 55 with 5 years service with an additional 10% vesting each additional year of service up to 10 years of service. Prior to fiscal year 2013, awards vested at age 65 or 55 and 10 years of service.											The total grant date fair value of stock options vested during fiscal 2013, fiscal 2012, and fiscal 2011, was $20 million, $27 million, and $40 million, respectively. The cash received from stock options exercised during fiscal 2013, fiscal 2012, and fiscal 2011, was $55 million, $15 million, and $73 million, respectively.
	Information concerning RSUs granted under stock incentive plans is as follows:											As of March 29, 2013, there was $27 million of unrecognized compensation expense related to unvested stock options, net of expected forfeitures.

The new operating model supports the execution of CSC's strategy by facilitating the effective development, sales and support of a portfolio of next generation offerings for commercial and government clients. The redesigned operating model resulted in a change to the Company's reportable segments effective at the beginning of fiscal 2014.
	CSC's applications development, testing, and maintenance businesses were transferred from the former MSS segment to the former Business Solutions and Services segment, resulting in the new GIS and GBS reportable segments, respectively. There were no changes to the NPS reportable segment.																		CSC's applications development, testing, and maintenance businesses were transferred from the former MSS segment to the former Business Solutions and Services segment, resulting in the new GIS and GBS reportable segments, respectively. Cloud was identified as a fourth operating segment and is aggregated within the GIS reportable segment due to its relatively small size. There were no changes to the NPS reportable segment.
	The Company’s new reportable segments are as follows:																		The Company's new reportable segments are as follows:
	•	GBS – The GBS segment comprises three units: Consulting, Industry Software & Solutions, and Applications Services.

Actions under the Fiscal 2012 Plan commenced in March 2012 were carried out through the third quarter of fiscal 2013, with only the payments against the liability continuing into fiscal 2014. There were no restructuring costs for the Fiscal 2012 Plan accrued during the first quarter of fiscal 2014.

			Interim Agreement Contract Change Note
	On August 31, 2012, the Company and the NHS entered into a binding interim agreement which has been approved by all required U.K. government officials ("interim agreement contract change note" or "IACCN"). The IACCN, which is described in greater detail below, amended the terms of the parties' then current contract under which the Company has developed and deployed an integrated patient records system using the Company's Lorenzo Regional Care software product. On March 28, 2013, the Company and the NHS signed a letter agreement that modified certain financial terms of the IACCN. The IACCN, and such letter agreement, forms the basis on which the parties will subsequently finalize a full restatement of the contract through a revised project agreement. The revised project agreement will consolidate the three regional contracts which comprise the Company's NHS contract into a single agreement. CSC and the NHS are in the process of negotiating the revised project agreement.

The revised project agreement will consolidate the three regional contracts which comprise the Company's NHS contract into a single agreement. CSC and the NHS are in the process of negotiating the revised project agreement.
	Under the IACCN, the parties redefined the scope of the Lorenzo products and established deployment and ongoing service pricing. CSC will deliver additional Lorenzo implementations based on demand from individual NHS trusts. A more flexible arrangement than under the contract terms existing prior to the IACCN has been established for these trusts to combine additional clinical modules with the core care management functionality of the Lorenzo solution to meet their specific requirements. CSC and the NHS also agreed to a process for trusts which wish to take the Lorenzo products within the NHS-designated North, Midlands and East regions of England (NME) to obtain central funding from the U.K. Department of Health for implementation of the Lorenzo products. Separately, CSC may offer the Lorenzo solution throughout the rest of England where trusts select CSC's solutions through separate competitive processes. Under the IACCN, the NHS is no longer subject to trust volume commitments and CSC has agreed to non-exclusive deployment rights in its designated regions. New trusts taking deployments of the Lorenzo product will receive ongoing managed services from CSC for a period of five years from the date of Lorenzo deployment by such trust, provided deployment is complete or substantially complete by July 2016. Beyond its Lorenzo offerings, CSC continues to provide a wide range of other solutions and services to the NHS, including general practitioner, ambulance and community systems, and other related services.

	Pursuant to the letter agreement signed on March 28, 2013, the parties agreed to modify a small number of financial terms of the IACCN and the NHS confirmed it would make a change compensation payment in accordance with the terms of the IACCN. The NHS paid the change compensation payment of £10 million($15 million) net of value added tax to CSC on March 28, 2013 in full and final satisfaction of all costs and claims by CSC arising from changes to the Lorenzo software product that CSC delivered up to a certain version of the product, in addition to a small number of other changes.

	Historical Background Concerning NHS Contract
			Historical Background Concerning NHS Contract
	The Company and the NHS are parties to a contract (originally having a value of £2.9 billion or approximately $5.4 billion at originally announced exchange rates) under which the Company has developed and deployed an integrated electronic patient records system. The NHS contract was amended in April 2009 and the parties entered into variation agreements subsequent to the 2009 amendment agreeing to various operational terms and conditions. The 2009 amendment included mutual releases of all claims existing at the time of the amendment.

The NHS contract was amended in April 2009 and the parties entered into variation agreements subsequent to the 2009 amendment agreeing to various operational terms and conditions. The 2009 amendment included mutual releases of all claims existing at the time of the amendment.
	In 2010, as part of the U.K. government's austerity program and to address delays in development and deployments, the Company and the NHS discussed modification of the contract scope in order to reduce the total contract value by £500 million. During the fourth quarter of fiscal year 2011, additional scope modification and total contract value reduction were discussed, bringing the combined total contract value reductions to £764 million, which would have reduced the total contract value to approximately £2.1 billion or $3.2 billion (at the June 28, 2013 exchange rate). Terms related to this scope modification and contract value reduction were included in a negotiated but unsigned non-binding memorandum of understanding (MOU), which MOU included a legally binding standstill agreement which provided that, while the parties were negotiating a contract amendment to implement the terms of the MOU, neither party would pursue any claims against the other party. Negotiation of the terms of the MOU was confirmed by the NHS to be substantially completed in May 2011, but CSC was subsequently informed by the NHS in December 2011 that neither the MOU nor the related contract amendment then under discussion would be approved by the U.K. government.

	Based on subsequent discussions between CSC and the NHS regarding proposals advanced by both parties reflecting significant scope modifications, a reduced commitment by the NHS for deployment of the Lorenzo software product, revised delivery and payment terms, payments by the NHS for CSC-incurred costs and commitment and contract value reductions that differed materially from those contemplated by the MOU, on March 2, 2012, CSC and the NHS entered into a non-binding letter of intent that included the statement of principles that would serve as the basis for an interim agreement between the parties. The letter of intent contemplated that under the interim agreement, the NHS would provide a commitment of a certain number of trusts to receive the Lorenzo software product, and the Lorenzo product was redefined into deployment units categorized as "Base Product" and "Additional Product" (in each case, as described below) for pricing purposes. The letter of intent also included a standstill agreement related to the Lorenzo product. While the parties originally intended to conclude a binding interim agreement by June 29, 2012, no agreement was reached by that date. On May 31, 2012, the standstill agreement was extended to August 31, 2012. On August 31, 2012, the parties entered into the IACCN. On March 28, 2013, the Company and the NHS signed a letter agreement that modified certain financial terms of the IACCN.

	The key terms introduced by the IACCN are as follows:
			The key terms introduced by the IACCN are as follows:
	1	Under contract terms existing prior to the IACCN, the NHS was committed to purchase the Lorenzo product for multiple trusts. In addition, the Company was the exclusive supplier of such software products and related services to two out of the three regions of the U.K. covered by the existing contract. Under the IACCN, the NHS is no longer subject to any trust volume commitment for the Lorenzo product (there were no changes in quantities for non-Lorenzo deployments), and the Company agreed to non-exclusive deployment rights for all products and services in those regions in which it previously enjoyed exclusivity. As a result, the individual trusts can choose third-party software vendors other than CSC to provide a software solution. CSC and the NHS have also agreed to a process for trusts which wish to take the Lorenzo products within the NME regions to obtain central funding from the U.K. Department of Health for implementation of the Lorenzo products. In addition, CSC may offer the Lorenzo solution throughout the rest of England where trusts select CSC's solutions through a separate competitive process.

While the funding is provided by the NHS, there is a far greater degree of interaction with the trusts under the IACCN, as the Company works with each individual trust to build a business case and seek NHS approval and central funding to proceed.

	3	The IACCN has not materially altered the terms relating to non-Lorenzo products.

	4	Under the IACCN, the Lorenzo product is redefined for pricing purposes, with Lorenzo Regional Care comprising the "Base Product," consisting of seven deployment units (or modules) and the "Additional Product," consisting of three other modules. The parties agreed that six of the Base Product's modules had completed the necessary NHS assurances and were ready to deploy to further trusts as of August 31, 2012. The remaining module of the Base Product was similarly accepted by the NHS as complete and ready to deploy to further trusts in early September 2012. The Additional Product's three modules are expected to complete NHS assurance during 2013. Although the NHS assurance of the Base Product's seven modules is complete and the Company and the NHS are committed to complete the assurance of the Additional Product modules, neither the NHS nor any trust is obligated to purchase or deploy any of those modules.

Under contract terms existing prior to the IACCN, all services were to expire upon the end of the contract term of July 7, 2016, subject to an optional one year extension and an exit transition period.

	Accounting
			Accounting
	Prior to the IACCN, the NHS contract has been accounted for using the percentage-of-completion method based on management's best estimates of total contract revenue and costs. Based on then existing circumstances, CSC revised its estimate of revenues and costs at completion during the third quarter of fiscal 2012 to include only those revenues reasonably assured of collection. As a result of that change, the Company recorded a $1.5 billion contract charge in that quarter, resulting in no material remaining net assets.

	The terms of the IACCN represent a significant modification to the prior agreement, including a significant reduction in additional product development and elimination of any commitment by the NHS to future Lorenzo deployments and the Company's exclusivity rights in two of the three contract regions. The Company concluded that it will account for the IACCN as a new contract and will recognize revenue as a services arrangement. Revenue recognition for each trust deployment will begin at the start of the trust's hosting period. Payments from the NHS for deployment of systems will be deferred and recognized over the service period. Direct costs incurred for deployment activities will be deferred and amortized to expense over the service period as well. The total up-front consideration of £78 million ($120 million), including the £68 million ($105 million) net settlement payment and a £10 million ($15 million) escrow release, is primarily attributed to future Lorenzo deployments and will be deferred and recognized into revenue ratably over the term of the contract ending July 2016. The £10 million ($15 million) payment received on March 28, 2013, as well as future consideration not noted above, when and if earned, will be deferred and amortized over the longer of the term of the contract or the estimated performance period.

Settlement of Claims with U.S. Government [Abstract]	'

	Settlement of Claims with U.S. Government
	During the second quarter of fiscal 2012, the Company reached a definitive settlement agreement with the U.S. government in its contract claims asserted under the Contract Disputes Act of 1978 (CDA). Under the terms of the settlement, the Company received $277 million in cash and a five-year extension (four base years plus one option year) with an estimated value of $1 billion to continue to support and expand the capabilities of the systems covered by the original contract scheduled to expire in December 2011. In exchange, the Government received unlimited rights to the Company’s intellectual property developed to support the services delivered under the contract, and CSC dismissed the claims and terminated legal actions against the Government and the Government dismissed its counter claims against CSC. The contract extension contained a Requirements portion (Federal Acquisition Regulation (“FAR”) 16.503) and an Indefinite Quantity portion (FAR 16.504) and is not subject to any minimum values. In December 2011, the Company signed the contract modification based on the terms described above.
	The Company recorded a pre-tax charge of $269 million during the second quarter of fiscal 2012 to write down its claim related assets (claim related unbilled receivables of $379 million and deferred costs of $227 million) to reflect the cash received of $277 million, the estimated fair value of the contract extension of $45 million, and previously unapplied payments of $15 million. Of the pre-tax charge of $269 million, $42 million was recorded as a reduction of revenue and $227 million as a separately itemized charge to cost of services. The fair value of the contract extension was recorded as a contract asset and will be amortized as a reduction of revenue over the four year fixed contract term in proportion to the expected revenues or on a straight line basis, whichever is greater.
	These claims relate to a contract that was awarded (the “Contract”) in December 1999 as a 10 year fixed price contract. In April 2004, the contract was extended by two additional years. Revenue recorded under the core Contract was initially recognized as a single profit center using the percentage-of-completion method based on the guidance in ASC 605-35, “construction-type and production-type contracts.”
	During the course of the contract, CSC incurred significant costs for out-of-scope work that was a result of Government directed changes and delays. Negotiations with the Government were initiated to recover the costs related to this work. During the second quarter of fiscal 2007, the Company filed its 14 interest bearing claims (collectively the “CDA Claims”), then totaling approximately $858 million, with the Government.  On September 11, 2007, the Company initiated litigation at the Armed Services Board of Contract Appeals (“ASBCA”), one of the two forums available for litigation of CDA claims.
	In accordance with accepted practice, the Company amended its CDA Claims twice to reflect adjustments to the total value of the CDA Claims.  On December 24, 2009, the Government made a partial payment of $35 million on one of the CDA Claims.  Thereafter, CSC filed a second amended complaint with the ASBCA reducing the value of its CDA Claims by $35 million. On November 19, 2010, the Government and the Company entered into a formal agreement to stay the CDA Claims litigation and engage in a non-binding alternate dispute resolution (“ADR”) process to resolve all outstanding CDA Claims and other issues associated with the contract. As of July 1, 2011, the Company had fourteen claims totaling approximately $675 million, excluding interest, asserted against the U.S. federal government under a single contract pending before the ASBCA.
	Prior to the settlement, the Company believed it had valid bases for pursuing recovery of the CDA Claims supported by outside counsel’s evaluation of the facts and assistance in the preparation of the claims. To verify its position, CSC requested that outside counsel analyze whether the first two conditions of Paragraph 31 of ASC 605-35-25 were satisfied with respect to the Company’s assertions of government breaches of the contract, government-caused delays and disruption to the Company’s performance of the contract, and unanticipated additional work performed by the Company under the contract. The outside counsel issued an opinion that the Company’s position met the criteria on April 22, 2005, and reiterated that opinion on May 20, 2011.

	In the normal course of business, the Company may provide certain clients, principally governmental entities, with financial performance guarantees, which are generally backed by stand-by letters of credit or surety bonds. In general, the Company would only be liable for the amounts of these guarantees in the event that nonperformance by the Company permits termination of the related contract by the Company’s client. As of June 28, 2013, the Company had $30 million of outstanding surety bonds and $131 million of outstanding letters of credit relating to these performance guarantees. 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 affect on its consolidated results of operations or financial position.									The Company has operating leases for the use of certain real estate and equipment. Substantially all operating leases are non-cancelable or cancelable only by the payment of penalties. All lease payments are based on the lapse of time but include, in some cases, payments for insurance, maintenance and property taxes. There are no purchase options on operating leases at favorable terms, but most real estate leases have one or more renewal options. Certain leases on real estate are subject to annual escalations for increases in utilities and property taxes. Lease rental expense amounted to $319 million, $324 million, and $330 million, for the years ended March 29, 2013, March 30, 2012, and April 1, 2011, respectively. In addition, the Company also has $18 million of sublease income to be received through fiscal 2020.
	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. As of June 28, 2013, the Company had $87 million of outstanding stand-by letters of credit.									Minimum fixed rentals required for the next five years and thereafter under operating leases in effect at March 29, 2013, are as follows:

	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), copyright, 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.									Thereafter	68		—

	The Company has a contract with the NHS to develop and deploy an integrated patient records system as a part of the U.K. Government's NHS IT program. On August 31, 2012, the Company and NHS entered into a binding interim agreement contract change note, or IACCN, which amends the terms of the current contract and forms the basis on which the parties will finalize a full restatement of the contract. On March 28, 2013, the Company and the NHS signed a letter agreement that modified certain terms of the IACCN. See Note 16 for further information relating to the NHS contract and the IACCN.
	As previously disclosed in fiscal 2012 and fiscal 2011, the Company initiated an investigation into out of period adjustments resulting from certain accounting errors in its former MSS segment, primarily involving accounting irregularities in the Nordic region. Initially, the investigation was conducted by Company personnel, but outside Company counsel and forensic accountants retained by such counsel later assisted in the Company's investigation. On January 28, 2011, the Company was notified by the SEC's Division of Enforcement that it had commenced a formal civil investigation relating to these matters, which investigation has been expanded to other matters subsequently identified by the SEC, including matters specified in subpoenas issued to the Company from time to time by the SEC's Division of Enforcement as well as matters under investigation by the Audit Committee, as further described below. The Company is cooperating in the SEC's investigation.									The Company has 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 five years. If the Company does not meet the specified minimums, the Company would have an obligation to pay the service provider all or a portion of the shortfall. Minimum purchase commitments are $478 million in fiscal 2014, $161 million in fiscal 2015, $132 million in fiscal 2016, $12 million in fiscal 2017, $2 million in fiscal 2018, and none thereafter.
	On May 2, 2011, the Audit Committee commenced an independent investigation into the matters relating to the MSS segment and the Nordic region, matters identified by subpoenas issued by the SEC's Division of Enforcement, and certain other accounting matters identified by the Audit Committee and retained independent counsel to represent CSC on behalf of, and under the exclusive direction of, the Audit Committee in connection with such independent investigation. Independent counsel retained forensic accountants to assist with their work. Independent counsel also represents CSC on behalf of, and under the exclusive direction of, the Audit Committee in connection with the investigation by the SEC's Division of Enforcement.									In the normal course of business, the Company may provide certain clients, principally governmental entities, with financial performance guarantees, which are generally backed by stand-by letters of credit or surety bonds. In general, the Company would only be liable for the amounts of these guarantees in the event that nonperformance by the Company permits termination of the related contract by the Company’s client. As of March 29, 2013, the Company had $122 million of outstanding letters of credit and surety bonds relating to these performance guarantees. 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 affect on its consolidated results of operations or financial position.
	The Audit Committee’s investigation was expanded to encompass (i) the Company’s operations in Australia, (ii) certain aspects of the Company’s accounting practices within its Americas Outsourcing operation, and (iii) certain of the Company’s accounting practices that involve the percentage-of-completion accounting method, including the Company’s contract with the NHS. In the course of the Audit Committee's expanded investigation, accounting errors and irregularities were identified. As a result, certain personnel have been reprimanded, suspended, terminated and/or have resigned. The Audit Committee determined in August 2012 that its independent investigation was complete. The Audit Committee instructed its independent counsel to cooperate with the SEC's Division of Enforcement by completing production of documents and providing any further information requested by the SEC's Division of Enforcement.									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. As of March 29, 2013, the Company had $183 million of outstanding stand-by letters of credit. Generally, such guarantees have a one-year term and are renewed annually.
	In addition to the matters noted above, the SEC's Division of Enforcement is continuing its investigation involving its concerns with certain of the Company's prior disclosure and accounting determinations with respect to the Company's contract with NHS and the possible impact of such matters on the Company's financial statements for years prior to the Company's current fiscal year. The Company and the Audit Committee and its independent counsel are continuing to respond to SEC questions and to cooperate with the SEC's Division of Enforcement in its investigation of prior disclosures of the Company's contract with the NHS. The SEC's investigative activities are ongoing.									The following table summarizes the expiration of the Company’s financial guarantees and stand-by letters of credit outstanding as of March 29, 2013:
	In addition, the SEC's Division of Corporation Finance has issued comment letters to the Company requesting, among other things, additional information regarding its previously disclosed adjustments in connection with the above-referenced accounting errors, the Company's conclusions relating to the materiality of such adjustments, and the Company's analysis of the effectiveness of its disclosure controls and procedures and its internal control over financial reporting. The SEC's Division of Corporation Finance's comment letter process is ongoing, and the Company is continuing to cooperate with that process.

	The investigation being conducted by the SEC's Division of Enforcement and the review of our financial disclosures by the SEC's Division of Corporation Finance are continuing and could identify other accounting errors, irregularities or other areas of review. As a result, CSC has incurred and may continue to incur significant legal and accounting expenditures. The Company is unable to predict how long the SEC's Division of Enforcement's investigation will continue or whether, at the conclusion of its investigation, the SEC will seek to impose fines or take other actions against the Company. In addition, the Company is unable to predict the timing of the completion of the SEC's Division of Corporation Finance's review of its financial disclosures or the outcome of such review. Publicity surrounding the foregoing or any enforcement action as a result of the SEC's investigation, even if ultimately resolved favorably for CSC, could have an adverse impact on the Company's reputation, business, financial condition, results of operations or cash flows. The Company is unable to estimate any possible loss or range of loss associated with these matter at this time. See Note 4 for further information.									Surety bonds	$	29	$	1	$	—	$	30
	Between June 3, 2011, and July 21, 2011, four putative class action complaints were filed in the United States District Court for the Eastern District of Virginia, entitled City of Roseville Employee's Retirement System v. Computer Sciences Corporation, et al. (No. 1:11-cv-00610-TSE-IDD), Murphy v. Computer Sciences Corporation, et al. (No. 1:11-cv-00636-TSE-IDD), Kramer v. Computer Sciences Corporation, et al. (No. 1:11-cv-00751-TSE-IDD) and Goldman v. Computer Sciences Corporation, et al. (No. 1:11-cv-777-TSE-IDD). On August 29, 2011, the four actions were consolidated as In re Computer Sciences Corporation Securities Litigation (No. 1:11-cv-610-TSE-IDD) and Ontario Teachers' Pension Plan Board was appointed lead plaintiff. A consolidated class action complaint was filed by plaintiff on September 26, 2011, and names as defendants CSC, Michael W. Laphen, Michael J. Mancuso and Donald G. DeBuck. A corrected complaint was filed on October 19, 2011. The complaint alleges violations of the federal securities laws in connection with alleged misrepresentations and omissions regarding the business and operations of the Company. Specifically, the allegations arise from the Company's disclosure of the Company's investigation into certain accounting irregularities in the Nordic region and its disclosure regarding the status of the Company's agreement with the NHS. Among other things, the plaintiff seeks unspecified monetary damages. The plaintiff filed a motion for class certification with the court on September 22, 2011, and the defendants filed a motion to dismiss on October 18, 2011. A hearing was held on November 4, 2011. On August 29, 2012, the court issued a Memorandum Opinion and Order granting in part and denying in part the motion to dismiss. The court granted the motion to dismiss with respect to the plaintiff's claims in connection with alleged misrepresentations and omissions concerning the Company's operations in the Nordic Region. The court granted in part and denied in part the motion to dismiss with respect to the plaintiff's claims in connection with alleged misrepresentations and omissions concerning the Company's internal controls and the Company's contract with the NHS. The court also granted the plaintiff leave to amend its complaint by September 12, 2012, and maintained the stay of discovery until the sufficiency of the amended complaint had been decided. The court further denied plaintiff's motion for class certification without prejudice. On September 12, 2012, the plaintiff filed a notice advising the Court that it had determined not to amend its complaint and renewed its motion for class certification. On September 21, 2012, the court issued an Order setting the hearing on the motion for class certification for October 12, 2012, directing the parties to complete discovery by January 11, 2013 and scheduling the final pretrial conference for January 17, 2013. On October 9, 2012, the defendants filed their answer to the plaintiff's complaint. On October 12, 2012, the hearing on the motion for class certification was rescheduled to November 1, 2012. On October 31, 2012, the parties filed a joint motion with the court requesting that the hearing on the motion for class certification be rescheduled to a later date. On November 1, 2012, the court issued an order setting the hearing for class certification for November 15, 2012. On November 30, 2012, the court granted plaintiff's motion for class certification. On December 14, 2012, defendants filed with the Fourth Circuit a petition for permission to appeal the class certification order pursuant to Federal Rule of Civil Procedure 23(f). Plaintiff's response to the petition was filed on February 20, 2013. On March 5, 2013, the Fourth Circuit denied the petition for permission to appeal the class certification order. On December 14, 2012, the court issued an order extending the expert discovery deadline to February 25, 2013. On December 20, 2012, the court issued an order extending the fact discovery deadline to February 11, 2013 and the expert discovery deadline to March 25, 2013. On January 13, 2013, the court issued an order extending the expert discovery deadline to April 1, 2013. Motions for summary judgment were filed on March 18, 2013. On May 15, 2013, the Company entered into a stipulation and agreement of settlement with the lead plaintiff to settle all claims in the lawsuit for $97.5 million, which was accrued for as of March 29, 2013 and included in accrued expenses and other current liabilities on the Company's Consolidated Balance Sheet. As of March 29, 2013, the Company has also recorded a receivable of $45 million, which represents the amount recoverable under the Company's corporate insurance policies, and is included in receivables on the Company's Consolidated Balance Sheet. The agreement is subject to approval by the court. On May 24, 2013, the Court entered a Preliminary Approval Order Providing for Notice and Hearing in Connection with Proposed Class Action Settlement. The Preliminary Approval Order scheduled a Settlement Hearing for September 19, 2013.									Letters of credit	58		1		33		92
	On September 13, 2011, a shareholder derivative action entitled Che Wu Hung v. Michael W. Laphen, et al. (CL 2011 13376) was filed in Circuit Court of Fairfax County, Virginia, against Michael W. Laphen, Michael J. Mancuso, the members of the Audit Committee and the Company as a nominal defendant asserting claims for breach of fiduciary duty and contribution and indemnification relating to alleged failure by the defendants to disclose accounting and financial irregularities in the MSS segment, primarily in the Nordic region, and the Company's performance under the NHS agreement and alleged failure to maintain effective internal controls. The plaintiff seeks damages, injunctive relief and attorneys' fees and costs. On October 24, 2011, the defendants removed the action to the United States District Court for the Eastern District of Virginia. On November 23, 2011, the plaintiff filed a motion to remand the case to state court. Argument was held on December 15, 2011. During argument the plaintiff voluntarily dismissed his complaint without prejudice to refiling the action in state court. The Court granted the plaintiff's request, dismissed the complaint without prejudice and denied the motion to remand as moot. On December 22, 2011, the plaintiff refiled his complaint in Circuit Court of Fairfax County, Virginia in a shareholder derivative action entitled Che Wu Hung v. Michael W. Laphen, et al. (CL 2011 18046). Named as defendants are Michael W. Laphen, Michael J. Mancuso, the members of the Audit Committee and the Company as a nominal defendant. The complaint asserts claims for (i) breach of fiduciary duty relating to alleged failure by the defendants to disclose accounting and financial irregularities in the MSS segment, primarily in the Nordic region, the Company's performance under the NHS agreement and alleged failure to maintain effective internal controls and (ii) corporate waste. The plaintiff seeks damages, injunctive relief and attorneys' fees and costs. On April 6, 2012, the state court stayed the action until the earlier of (i) entry of an order on the pending motion to dismiss In re Computer Sciences Corporation Securities Litigation (No. 1:11-cv-610-TSE-IDD) or (ii) July 5, 2012. On July 20, 2012, the state court renewed the stay until the earlier of (i) entry of an order on the pending motion to dismiss in In re Computer Sciences Corporation Securities Litigation or (ii) October 18, 2012. The stay expired on August 30, 2012 with the entry of the court's order in In re Computer Sciences Corporation Securities Litigation. On October 19, 2012, upon the joint motion of the parties, the state court issued an order staying the action while discovery proceeded in In re Computer Sciences Corporation Securities Litigation. The order required defendants to provide to the plaintiff certain of the discovery produced in the federal action. On May 10, 2013, the court continued the stay to May 31, 2013 upon joint motion of the parties. On June 1, 2013, the parties filed a joint motion to continue the stay. On June 28, 2013, the court denied the joint motion to continue the stay and set the matter for trial on January 6, 2014. The parties have been engaged in good faith settlement negotiations and are working towards a potential resolution of the matter. The Company is unable to estimate any possible loss or range of loss associated with this matter at this time.									Stand-by letters of credit	37		132		14		183
	On May 11, 2012, a separate shareholder derivative action entitled Judy Bainto v. Michael W. Laphen et al. (No. A-12-661695-C), was filed in District Court, Clark County, Nevada, against Messrs. Laphen and Mancuso, members of the Company's Board of Directors and the Company as a nominal defendant. The complaint is substantively similar to the second Hung complaint. On or about August 1, 2012, the court granted the parties' joint motion to extend the time for defendants to respond to the complaint to sixty days after the United States District Court for the Eastern District of Virginia's entry of an order on the pending motion to dismiss the complaint in In re Computer Sciences Corporation Securities Litigation. On September 5, 2012, Defendants notified the court of the Eastern District of Virginia's ruling in In re Computer Sciences Corporation Securities Litigation. On September 11, 2012, the parties filed a joint status report proposing a schedule for the filing of an amended complaint by plaintiff and for motion to dismiss briefing. Plaintiff filed an amended complaint on September 28, 2012. Upon stipulation of the parties, the court consolidated the Bainto case and Himmel case (described below) and deemed the amended complaint filed in Bainto the operative complaint. In addition, on November 8, 2012, upon joint motion of the parties, the court issued an order staying the action while discovery proceeded in In re Computer Sciences Corporation Securities Litigation. The order required Defendants to provide to the Plaintiffs certain of the discovery produced in the federal action. A status check is set for August 15, 2013. The parties have been engaged in good faith settlement negotiations and are working towards a potential resolution of the matter.

	On October 16, 2012, a separate shareholder derivative action entitled Daniel Himmel v. Michael W. Laphen et al. (No. A-12-670190-C), was filed in District Court, Clark County, Nevada, against Messrs. Laphen and Mancuso, members of the Company's Board of Directors and the Company as a nominal defendant. The Himmel complaint is substantively similar to the Bainto complaint, but includes a claim for unjust enrichment and seeks additional injunctive relief. Upon stipulation of the parties, the court consolidated the Bainto case (describe above) and the Himmel case and deemed the amended complaint filed in Bainto the operative complaint. In addition, on November 8, 2012, upon joint motion of the parties, the court issued an order staying the action while discovery proceeded in In re Computer Sciences Corporation Securities Litigation. The order required Defendants to provide to the Plaintiffs certain of the discovery produced in the federal action. A status check is set for August 15, 2013. The parties have been engaged in good faith settlement negotiations and are working towards a potential resolution of the matter. The Company is unable to estimate any possible loss or range of loss associated with this matter at this time.
										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), copyright, 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.
	On December 20, 2012, a separate shareholder derivative complaint entitled Shirley Morefield v Irving W. Bailey, II, et al, (Case No. 1:120V1468GBL/TCB) was filed in the United States District Court for the Eastern District of Virginia. The complaint names certain of CSC's current and former directors and officers as defendants and the Company as a nominal defendant. The complaint is similar to the Hung complaint but asserts only a claim for breach of fiduciary duty and alleges that the plaintiff made a demand on the CSC Board prior to commencing suit and that such demand was refused. Motions to dismiss were filed on March 18, 2013. On April 8, 2013, Plaintiff filed an amended complaint. Motions to dismiss the amended complaint were filed on April 17, 2013 and were heard on May 10, 2013. A decision is pending. The Company is unable to estimate any possible loss or range of loss associated with this matter at this time.									Contingencies
	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 consults with legal counsel on those issues related to litigation and seeks input from other experts and advisors with respect to such matters in the ordinary course of business. Whether any losses, damages or remedies ultimately resulting from such matters could reasonably have a material effect on the Company's business, financial condition, results of operation, or cash flows will depend on a number of variables, including, for example, the timing and amount of such losses or damages (if any) and the structure and type of any such remedies.  For these reasons, it is not possible to make reasonable estimates of the amount or range of loss that could result from these other matters at this time. Company management does not, however, presently expect any of such other matters to have a material impact on the consolidated financial statements of the Company.									The Company has a contract with the NHS to develop and deploy an integrated patient records system as a part of the U.K. Government's NHS IT program. On August 31, 2012, the Company and NHS entered into a binding interim agreement contract change note, or IACCN, which amends the terms of the current contract and forms the basis on which the parties will finalize a full restatement of the contract. On March 28, 2013, the Company and the NHS signed a letter agreement that modified certain terms of the IACCN. See Note 18 for further information relating to the NHS contract and the IACCN.

The Company is cooperating in the SEC's investigation.
										On May 2, 2011, the Audit Committee commenced an independent investigation into the matters relating to the MSS segment and the Nordic region, matters identified by subpoenas issued by the SEC's Division of Enforcement, and certain other accounting matters identified by the Audit Committee and retained independent counsel to represent CSC on behalf of, and under the exclusive direction of, the Audit Committee in connection with such independent investigation. Independent counsel retained forensic accountants to assist with their work. Independent counsel also represents CSC on behalf of, and under the exclusive direction of, the Audit Committee in connection with the investigation by the SEC's Division of Enforcement.
										The Audit Committee’s investigation was expanded to encompass (i) the Company’s operations in Australia, (ii) certain aspects of the Company’s accounting practices within its Americas Outsourcing operation, and (iii) certain of the Company’s accounting practices that involve the percentage-of-completion accounting method, including the Company’s contract with the NHS. In the course of the Audit Committee's expanded investigation, accounting errors and irregularities were identified. As a result, certain personnel have been reprimanded, suspended, terminated and/or have resigned. The Audit Committee determined in August 2012 that its independent investigation was complete. The Audit Committee instructed its independent counsel to cooperate with the SEC's Division of Enforcement by completing production of documents and providing any further information requested by the SEC's Division of Enforcement.
										In addition to the matters noted above, the SEC's Division of Enforcement is continuing its investigation involving its concerns with certain of the Company's prior disclosure and accounting determinations with respect to the Company's contract with NHS and the possible impact of such matters on the Company's financial statements for years prior to the Company's current fiscal year. The Company and the Audit Committee and its independent counsel are investigating these matters and are continuing to cooperate with the SEC's Division of Enforcement in its investigation of prior disclosures of the Company's contract with the NHS. The SEC's investigative activities are ongoing.
										In addition, the SEC's Division of Corporation Finance has issued comment letters to the Company requesting, among other things, additional information regarding its previously disclosed adjustments in connection with the above-referenced accounting errors, the Company's conclusions relating to the materiality of such adjustments, and the Company's analysis of the effectiveness of its disclosure controls and procedures and its internal control over financial reporting. The SEC's Division of Corporation Finance's comment letter process is ongoing, and the Company is continuing to cooperate with that process.
										The investigation being conducted by the SEC's Division of Enforcement and the review of our financial disclosures by the SEC's Division of Corporation Finance are continuing and could identify other accounting errors, irregularities or other areas of review. As a result, we have incurred and may continue to incur significant legal and accounting expenditures. We are unable to predict how long the SEC's Division of Enforcement's investigation will continue or whether, at the conclusion of its investigation, the SEC will seek to impose fines or take other actions against the Company. In addition, we are unable to predict the timing of the completion of the SEC's Division of Corporation Finance's review of our financial disclosures or the outcome of such review. Publicity surrounding the foregoing or any enforcement action as a result of the SEC's investigation, even if ultimately resolved favorably for us, could have an adverse impact on the Company's reputation, business, financial condition, results of operations or cash flows.

On December 20, 2012, the court issued an order extending the fact discovery deadline to February 11, 2013 and the expert discovery deadline to March 25, 2013. On January 13, 2013, the court issued an order extending the expert discovery deadline to April 1, 2013. Motions for summary judgment were filed on March 18, 2013. On May 15, 2013, the Company entered into a stipulation and agreement of settlement with the lead plaintiff to settle all claims in the lawsuit for $97.5 million, which was accrued for as of March 29, 2013 and included in accrued expenses and other current liabilities on the Company's Consolidated Balance Sheet. As of March 29, 2013, the Company has also recorded a receivable of $45 million, which represents the amount recoverable under the Company's corporate insurance policies, and is included in receivables on the Company's Consolidated Balance Sheet. The agreement is subject to approval by the court.
										On September 13, 2011, a shareholder derivative action entitled Che Wu Hung v. Michael W. Laphen, et al. (CL 2011 13376) was filed in Circuit Court of Fairfax County, Virginia, against Michael W. Laphen, Michael J. Mancuso, the members of the Audit Committee and the Company as a nominal defendant asserting claims for breach of fiduciary duty and contribution and indemnification relating to alleged failure by the defendants to disclose accounting and financial irregularities in the MSS segment, primarily in the Nordic region, and the Company's performance under the NHS agreement and alleged failure to maintain effective internal controls. The plaintiff seeks damages, injunctive relief and attorneys' fees and costs. On October 24, 2011, the defendants removed the action to the United States District Court for the Eastern District of Virginia. On November 23, 2011, the plaintiff filed a motion to remand the case to state court. Argument was held on December 15, 2011. During argument the plaintiff voluntarily dismissed his complaint without prejudice to refiling the action in state court. The Court granted the plaintiff's request, dismissed the complaint without prejudice and denied the motion to remand as moot. On December 22, 2011, the plaintiff refiled his complaint in Circuit Court of Fairfax County, Virginia in a shareholder derivative action entitled Che Wu Hung v. Michael W. Laphen, et al. (CL 2011 18046). Named as defendants are Michael W. Laphen, Michael J. Mancuso, the members of the Audit Committee and the Company as a nominal defendant. The complaint asserts claims for (i) breach of fiduciary duty relating to alleged failure by the defendants to disclose accounting and financial irregularities in the MSS segment, primarily in the Nordic region, the Company's performance under the NHS agreement and alleged failure to maintain effective internal controls and (ii) corporate waste. The plaintiff seeks damages, injunctive relief and attorneys' fees and costs. On April 6, 2012, the state court stayed the action until the earlier of (i) entry of an order on the pending motion to dismiss In re Computer Sciences Corporation Securities Litigation (No. 1:11-cv-610-TSE-IDD) or (ii) July 5, 2012. On July 20, 2012, the state court renewed the stay until the earlier of (i) entry of an order on the pending motion to dismiss in In re Computer Sciences Corporation Securities Litigation or (ii) October 18, 2012. The stay expired on August 30, 2012 with the entry of the court's order in In re Computer Sciences Corporation Securities Litigation. On October 19, 2012, upon the joint motion of the parties, the state court issued an order staying the action while discovery proceeds in In re Computer Sciences Corporation Securities Litigation. The order requires defendants to provide to the plaintiff certain of the discovery produced in the federal action. On May 10, 2013, the court continued the stay to May 31, 2013 upon joint motion of the parties. The Company is unable to estimate any possible loss or range of loss associated with this matter at this time.
										On May 11, 2012, a separate shareholder derivative action entitled Judy Bainto v. Michael W. Laphen et al. (No. A-12-661695-C), was filed in District Court, Clark County, Nevada, against Messrs. Laphen and Mancuso, members of the Company's Board of Directors and the Company as a nominal defendant. The complaint is substantively similar to the second Hung complaint. On or about August 1, 2012, the court granted the parties' joint motion to extend the time for defendants to respond to the complaint to sixty days after the United States District Court for the Eastern District of Virginia's entry of an order on the pending motion to dismiss the complaint in In re Computer Sciences Corporation Securities Litigation. On September 5, 2012, Defendants notified the court of the Eastern District of Virginia's ruling in In re Computer Sciences Corporation Securities Litigation. On September 11, 2012, the parties filed a joint status report proposing a schedule for the filing of an amended complaint by plaintiff and for motion to dismiss briefing. Plaintiff filed an amended complaint on September 28, 2012. Upon stipulation of the parties, the court consolidated the Bainto case and Himmel case (described below) and deemed the amended complaint filed in Bainto the operative complaint. In addition, on November 8, 2012, upon joint motion of the parties, the court issued an order staying the action while discovery proceeds in In re Computer Sciences Corporation Securities Litigation. The order requires Defendants to provide to the Plaintiffs certain of the discovery produced in the federal action. The Company is unable to estimate any possible loss or range of loss associated with this matter at this time.
										On October 16, 2012, a separate shareholder derivative action entitled Daniel Himmel v. Michael W. Laphen et al. (No. A-12-670190-C), was filed in District Court, Clark County, Nevada, against Messrs. Laphen and Mancuso, members of the Company's Board of Directors and the Company as a nominal defendant. The Himmel complaint is substantively similar to the Bainto complaint, but includes a claim for unjust enrichment and seeks additional injunctive relief. Upon stipulation of the parties, the court consolidated the Bainto case (describe above) and the Himmel case and deemed the amended complaint filed in Bainto the operative complaint. In addition, on November 8, 2012, upon joint motion of the parties, the court issued an order staying the action while discovery proceeds in In re Computer Sciences Corporation Securities Litigation. The order requires Defendants to provide to the Plaintiffs certain of the discovery produced in the federal action. The Company is unable to estimate any possible loss or range of loss associated with this matter at this time.
										On December 20, 2012, a separate shareholder derivative complaint entitled Shirley Morefield v Irving W. Bailey, II, et al, (Case No. 1:120V1468GBL/TCB) was filed in the United States District Court for the Eastern District of Virginia. The complaint names certain of CSC's current and former directors and officers as defendants and the Company as a nominal defendant. The complaint is similar to the Hung complaint but asserts only a claim for breach of fiduciary duty and alleges that the plaintiff made a demand on the CSC Board prior to commencing suit and that such demand was refused. Motions to dismiss were filed March 18, 2013. On April 8, 2013, Plaintiff filed an amended complaint. Motions to dismiss the amended complaint were filed on April 17, 2013 and were heard on May 10, 2013. A decision is pending. The Company is unable to estimate any possible loss or range of loss associated with this matter at this time.
										On October 19, 2012, a putative class action complaint was filed in the United States District Court of the Southern District of Indiana, entitled Andrea M. Childress v. Experian Information Services, Inc. and CSC Credit Services , Inc. The complaint alleges Fair Credit Reporting Act claims regarding reports prepared about consumers who filed for Chapter 13 bankruptcy protection and subsequently withdrew their bankruptcy filing before court approval of a bankruptcy plan. Plaintiff, on behalf of the class, seeks statutory and punitive damages, injunctive relief and attorneys' fees. On February 4, 2013, CSC was dismissed without prejudice from this lawsuit by plaintiff's notice filed with the court.
										The Company's net legal expenses associated with the SEC investigation and class action lawsuits were $33 million, $67 million, and $2 million, for fiscal years 2013, 2012 and 2011, respectively. During fiscal 2013, the Company incurred $78 million, which was partially offset by $45 million of insurance claims.
										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 consults with legal counsel on those issues related to litigation and seeks input from other experts and advisors with respect to such matters in the ordinary course of business. Whether any losses, damages or remedies ultimately resulting from such matters could reasonably have a material effect on the Company's business, financial condition, results of operation, or cash flows will depend on a number of variables, including, for example, the timing and amount of such losses or damages (if any) and the structure and type of any such remedies.  For these reasons, it is not possible to make reasonable estimates of the amount or range of loss that could result from these other matters at this time. Company management does not, however, presently expect any of such other matters to have a material impact on the consolidated financial statements of the Company.

								Basis of Presentation and Principles of Consolidation
	Computer Sciences Corporation (CSC or the Company) has prepared the interim period unaudited Consolidated Condensed Financial Statements included herein, as of and for the quarters ended June 28, 2013 and June 29, 2012, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (GAAP) have been condensed or omitted pursuant to such rules and regulations. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Condensed Financial Statements and the accompanying notes. It is recommended that these Consolidated Condensed Financial Statements be read in conjunction with the financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended March 29, 2013 (fiscal 2013). In the opinion of management, the unaudited Consolidated Condensed Financial Statements included herein reflect all adjustments necessary, including those of a normal recurring nature, to present fairly the financial position, the results of operations and the cash flows for such interim periods. The results of operations for such interim periods are not necessarily indicative of the results for the full year ending March 28, 2014 (fiscal 2014).
								The accompanying consolidated financial statements and notes are those of Computer Sciences Corporation, its subsidiaries, and those business entities in which the Company maintains a controlling interest, hereafter collectively referred to as “CSC” or “the Company.” Investments in business entities in which the Company does not have control, but has the ability to exercise significant influence over operating and financial policies, are accounted for by the equity method. Other investments are accounted for by the cost method. All intercompany transactions and balances have been eliminated.
	With the beginning of fiscal 2014, the Company began operating under new reportable segments. The new reportable segments are North American Public Sector (NPS), Global Infrastructure Services (GIS) and Global Business Services (GBS) (see Note 13). All prior period segment disclosures have been recast to reflect the Company's change in reportable segments.
								The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC).
	The Consolidated Condensed Statements of Operations, of Comprehensive Income (Loss) and of Changes in Equity, along with the related notes, for the quarter ended June 29, 2012, have been recast from those presented in the previously filed Form 10-Q to reflect discontinued operations of the two businesses sold in fiscal 2014, the three businesses sold in fiscal 2013 (see Note 3), as well as the business that CSC has committed to a plan to sell (see Notes 3 and 18).
								Effective at the beginning of fiscal 2014, the Company began operating under new reportable segments. The new reportable segments are Global Business Services (GBS), Global Infrastructure Services (GIS) and North American Public Sector (NPS) (see Note 16). All prior period segment disclosures have been recast to reflect the Company's change in reportable segments.
	The Consolidated Condensed Balance Sheet for the year ended March 29, 2013 has not been recast to reflect the assets and liabilities divested as a result of the two fiscal 2014 discontinued operations. The Consolidated Condensed Statements of Cash Flows for the quarters ended June 28, 2013 and June 29, 2012 include both continuing and discontinued operations.
								The Consolidated Statements of Operations, Consolidated Statements of Comprehensive Income, and related notes, for the fiscal years ended March 29, 2013, March 30, 2012 and April 1, 2011, have been recast from those presented in the previously filed Form 10-K to reflect discontinued operations of the three businesses sold in fiscal 2014, as well as the business that CSC has committed to a plan to sell (see Notes 3 and 21).
	The Company's income from continuing operations, before taxes and noncontrolling interest, and diluted earnings per share (EPS) from continuing operations included the following adjustments due to changes in estimated profitability on fixed price contracts accounted for under the percentage-of-completion method for the quarters presented:
								The Consolidated Balance Sheets for the years ended March 29, 2013 and March 30, 2012 have not been recast to reflect the assets and liabilities divested as a result of sale of the two businesses. The Consolidated Statements of Cash Flows for all the fiscal years presented include both continuing and the discontinued operations.

	Gross favorable	$	17		$	9
								GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. These estimates are based on management’s best knowledge of historical experience, current events, and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from these estimates. Amounts subject to significant judgment and estimates include, but are not limited to, contracts accounted for using the percentage-of-completion method, cash flows used in the evaluation of impairment of goodwill and other long-lived assets, intangible assets, certain deferred costs, collectability of receivables, reserves for uncertain tax benefits, valuation allowances on deferred tax assets, loss accruals for litigation, pension related liabilities, inputs used for computing stock-based compensation and the fair value of derivative instruments.

	Unbilled recoverable amounts under contracts in progress do not have an allowance for credit losses, and therefore, any adjustments to unbilled recoverable amounts under contracts in progress related to credit quality would be accounted for as a reduction of revenue. Unbilled recoverable amounts under contracts in progress resulting from sales, primarily to the United States (U.S.) and other governments, that are expected to be collected after one year totaled $44 million and $48 million as of June 28, 2013 and March 29, 2013, respectively.

								(2)	Quarterly changes in estimated profitability on the same fixed price contract are disclosed gross as either favorable or unfavorable.
								Revenue Recognition
								The Company's primary service offerings are information technology (IT) outsourcing, and both IT and other professional services. Revenues are recognized when persuasive evidence of an arrangement exists, services or products have been provided to the client, the sales price is fixed or determinable, and collectability is reasonably assured. For non-software arrangements that include multiple-elements, revenue recognition involves the identification of separate units of accounting after consideration of combining and/or segmenting contracts and allocation of the arrangement consideration to the units of accounting on the basis of their relative selling price. Revenue under such contracts is recognized based upon the levels of services delivered in the periods in which they are provided. Upfront fees for the contract set-up activities are deferred and recognized ratably over the period of performance. Costs are expensed as incurred except for direct and incremental set-up costs that are capitalized and amortized over the life of the agreement (see Outsourcing Contract Costs below). See the section below regarding software transactions that include multiple elements.
								The Company provides these services under time and materials, cost-reimbursable, unit-price and fixed-price contracts, the revenue for which is recognized in the following manner:
								Time and materials contracts - Revenue is recorded at agreed-upon billing rates at the time services are provided.
								Cost-reimbursable contracts - Revenue is recorded at the time costs are incurred and associated fees are recognized when probable and estimable by applying an estimated factor to costs as incurred, such factor being determined by the contract provisions and prior experience.
								Unit-price contracts - Revenue is recognized on unit-price contracts based on unit metrics multiplied by the agreed upon contract unit price or when services are delivered.
								Fixed-price contracts - For certain fixed-price contracts, revenue is recognized under the percentage-of-completion method as described below; these include certain software development projects, all long-term construction-type contracts, and certain fixed-price arrangements with the U.S. federal government. For other fixed-price contracts, revenue is recognized based on the proportion of the services delivered to date as a percentage of the total services to deliver over the contract term. If output or input measures are not available or cannot be reasonably estimated, revenues are recognized ratably over the contract term.
								Under the percentage-of-completion method, progress towards completion is measured based on either achievement of specified contract milestones, costs incurred as a proportion of estimated total costs, or other measures of progress when available. Profit in a given period is reported at the estimated profit margin to be achieved on the overall contract. This method can result in the recognition of unbilled receivables, the deferral of costs as work in process, or deferral of profit on these contracts. Contracts that require estimates at completion using the percentage-of-completion method accounted for approximately 17.9% of the Company's revenues for fiscal 2013. Management regularly reviews project profitability and underlying estimates. Revisions to the estimates at completion are reflected in results of operations as a change in accounting estimate in the period in which the facts that give rise to the revision become known by management. Provisions for estimated losses at completion, if any, are recognized in the period in which the loss becomes evident. The provision includes estimated costs in excess of estimated revenue and any profit margin previously recognized.
								Multiple-element software sales - For multiple-element arrangements that involve the sale of CSC proprietary software, post contract customer support, and other software-related services, vendor-specific objective evidence (VSOE) of fair value is required to allocate and recognize revenue for each element. VSOE of fair value is determined based on the price charged where each deliverable is sold separately. In situations where VSOE of fair value exists for all undelivered elements but not a delivered element (typically the software license element), the residual method is used to allocate revenue to the undelivered elements equal to their VSOE value with the remainder allocated to the delivered element. If significant customization is required, and VSOE is available to support accounting for the software as a separate unit of account, software revenue is recognized as the related software customization services are performed in accordance with the percentage-of-completion method described above. In situations where VSOE of fair value does not exist for all of the undelivered software-related elements, revenue is deferred until only one undelivered element remains and then recognized following the pattern of delivery of the final undelivered element.
								Depreciation and Amortization
								The Company’s depreciation and amortization policies are as follows:
								Property and Equipment:
								Buildings	Up to 40 years
								Computers and related equipment	3 to 5 years
								Furniture and other equipment	2 to 15 years
								Leasehold improvements	Shorter of lease term or useful life
								Software	2 to 10 years
								Outsourcing contract costs	Contract life, excluding option years
								Customer related intangibles	Expected customer service life
								Acquired contract related intangibles	Contract life and first contract renewal, where applicable
								The cost of property and equipment, less applicable residual values, is depreciated using predominately the straight-line method. Depreciation commences when the specific asset is complete, installed and ready for normal use. Depreciation expense for fiscal years 2013, 2012, and 2011 was $709 million, $754 million, and $685 million, respectively.
								Software and outsourcing contract costs are amortized using predominately the straight-line method. Acquired contract related and customer related intangible assets are amortized in proportion to the estimated undiscounted cash flows projected over the estimated life of the asset or on a straight-line basis if such cash flows cannot be reliably estimated.
								Software Development Costs
								The Company capitalizes costs incurred to develop commercial software products after technological feasibility has been established. Costs incurred to establish technological feasibility are charged to expense as incurred. Enhancements to software products are capitalized where such enhancements extend the life or significantly expand the marketability of the products. Amortization of capitalized software development costs is determined separately for each software product. Annual amortization expense is calculated based on the greater of (a) the ratio of current gross revenues for each product to the total of current anticipated future gross revenues for the product or (b) the straight-line method over the estimated economic life of the product.
								Unamortized capitalized software costs associated with commercial software products are regularly evaluated for impairment on a product-by-product basis by a comparison of the unamortized balance to the product’s net realizable value. The net realizable value is the estimated future gross revenues from that product reduced by the related estimated future costs. When the unamortized balance exceeds the net realizable value, the unamortized balance is written down to the net realizable value and an impairment charge is recorded.
								The Company capitalizes costs incurred to develop internal-use computer software. Internal and external costs incurred in connection with development of upgrades or enhancements that result in additional functionality are also capitalized. These capitalized costs are amortized on a straight-line basis over the estimated useful life of the software. Purchased software is capitalized and amortized over the estimated useful life of the software.
								Outsourcing Contract Costs
								Costs on outsourcing contracts, including costs incurred for bid and proposal activities, are generally expensed as incurred. However, certain costs incurred upon initiation of an outsourcing contract are deferred and expensed over the contract life. These costs represent incremental external costs or certain specific internal costs that are directly related to the contract acquisition or transition activities. Such capitalized costs can be separated into two principal categories: contract acquisition costs and transition/set-up costs. The primary types of costs that may be capitalized include labor and related fringe benefits, subcontractor costs, travel costs, and premiums on asset purchases.
								Premiums are amounts paid to customers in excess of the fair market value of assets acquired. Fixed assets acquired in connection with outsourcing transactions are capitalized at fair value and depreciated consistent with the fixed asset policies described above. Premiums paid are capitalized as outsourcing contract costs and amortized over the contract life. The amortization of outsourcing contract cost premiums is accounted for as a reduction in revenue. The second principal category of capitalized outsourcing costs is transition/set-up costs. Such costs are primarily associated with the installation of systems and processes and are amortized over the contract life.
								In the event indications exist that an outsourcing contract cost balance related to a particular contract may be impaired, undiscounted estimated cash flows of the contract are projected over its remaining term and compared to the associated long-lived asset group including the unamortized outsourcing contract cost balance. If the projected cash flows are not adequate to recover the unamortized cost balance of the asset group, the balance would be adjusted based on the fair value of the long-lived assets group in the period such a determination is made. The primary indicator used to determine when impairment testing should be performed is when a contract is materially underperforming, or is expected to materially underperform in the future, as compared to the original bid model or subsequent annual budgets.
								Terminations of outsourcing contracts, including transfer of assets either back to the customer or to another IT provider, prior to the end of their committed contract terms, are infrequent due to the complex transition of personnel, assets, methodologies, and processes involved with outsourcing transactions. In the event of an early termination, the Company and the customer, pursuant to certain contractual provisions, engage in discussions to determine the recovery of unamortized contract costs, lost profits, transfer of personnel, rights to implemented systems and processes, as well as other matters.
								Stock-Based Compensation
								The Company provides different forms of stock-based compensation to its employees and nonemployee directors. For awards settled in shares, the Company recognizes compensation expense based on the grant-date fair value net of estimated forfeitures. For awards settled in cash, the Company recognizes compensation expense based on the fair value at each reporting date net of estimated forfeitures. The Company recognized stock-based compensation expense for fiscal 2013, fiscal 2012, and fiscal 2011 as follows:

							The Company’s overall stock-based compensation granting practice has not changed year-over-year, except that with fiscal 2012's long-term incentive program, service-based restricted stock units (RSUs) and performance-based RSUs represent a larger portion of total stock-based compensation awards than in the past.
							The increase in fiscal 2013 stock-based compensation expense was primarily due to performance-based RSUs granted in fiscal 2013 that increased the expense by $15 million. This increase was partially offset by a $3 million reduction of expense as a result of adjustments for expected achievement of the specified performance criteria for performance-based RSUs granted in previous fiscal years. Fiscal 2012 stock-based compensation expense included a $12 million reduction to expense for expected achievement of the specified performance criteria for performance-based RSUs granted in previous fiscal years. There were no such adjustments in fiscal 2011.
							The Company periodically evaluates its significant assumptions used in the fair value calculation. Beginning in fiscal 2011, the Company modified certain underlying assumptions in the fair value calculations, which did not have a material impact on the fair value calculations, as described below.
							The Company uses the Black-Scholes-Merton model in determining the fair value of options granted. The expected term is calculated based on the Company’s historical experience with respect to its stock plan activity in combination with an estimate of when vested and unexercised option shares will be exercised. The Company uses separate assumptions for the expected term of options granted based on two separate job tier classifications which had distinct historical exercise behavior. This resulted in separate fair value calculations by job tier. The risk-free interest rate is based on the zero coupon interest rate of U.S. government issued Treasury strips with a period commensurate with the expected term of the options. In determining the overall risk-free interest rate for fiscal 2013, a range of interest rates from 0.82% to 1.44% was applied depending on the expected life of the grant. The Company continued to base expected volatility on a blended approach using an equal weighting of implied volatility and historical volatility. However, beginning with the first quarter of fiscal 2011, the historical volatility calculation was based on the Company’s six-year and seven-year historical daily closing price, rather than the ten-year historical used in prior periods, in order to bring this factor more closely into alignment with the expected terms of the stock options. The range of volatility used for fiscal 2013 was 32% to 38%. The dividend yield assumption was added concurrent with the introduction of a cash dividend in fiscal 2011 and is based on the respective fiscal year dividend payouts. Forfeitures are estimated based on historical experience and adjustments are made annually to reflect actual forfeiture experience.
							The weighted average grant date fair values of stock options granted during fiscal 2013, fiscal 2012, and fiscal 2011 were $7.37, $10.17, and $12.95 per share, respectively. In calculating the compensation expense for its stock incentive plans, the Company used the following weighted average assumptions:
								Fiscal Year
								2013			2012			2011
							Risk-free interest rate	1.15	%		1.8	%		2.37	%
							Expected volatility	36	%		31	%		28	%
							Expected term (in years)	6.59			6.11			5.85
							Dividend yield	2.86	%		1.79	%		1.17	%
							During fiscal 2013, fiscal 2012, and fiscal 2011, the Company's actual tax benefit realized for tax deductions from exercising stock options was of $9 million, $7 million, and $11 million, respectively, and an excess tax benefit of $3 million, $2 million, and $6 million, respectively, related to all of its stock incentive plans.
							Acquisition Accounting and Goodwill
							Under acquisition accounting, the purchase price is allocated to the underlying tangible and intangible assets acquired and liabilities assumed based upon their respective fair market values, with the excess recorded as goodwill. Acquisition-related costs are expensed in the periods in which the costs are incurred, and the results of operations of acquired businesses are included in the Consolidated Financial Statements from the acquisition date.
							The Company tests goodwill for impairment on an annual basis, as of the first day of the second fiscal quarter, and between annual tests if circumstances change, of if an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. A significant amount of judgment is involved in determining whether an event indicating impairment has occurred between annual testing dates. Such indicators may include: a significant decline in expected future cash flows; a significant adverse change in legal factors or in the business climate; unanticipated competition; the disposal of a significant component of a reporting unit; and the testing for recoverability of a significant asset group within a reporting unit.
							The goodwill impairment test initially involves the assessment of qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is not more likely than not, then the subsequent two-step process is not required, although the Company has the option to bypass this initial qualitative assessment and proceed directly to step one of the two-step process. If the Company determines that it is more likely than not, then it proceeds with the subsequent two-step goodwill impairment testing process. The first step is to compare each reporting unit’s fair value to its carrying value. If the reporting unit’s fair value exceeds its carrying value, no further procedures are required. However, if a reporting unit’s fair value is less than its carrying value, an impairment of goodwill may exist, requiring a second step to measure the amount of impairment loss. In the second step, the reporting unit’s fair value is allocated to all of the assets and liabilities of the reporting unit, including any unrecognized intangible assets, in a hypothetical analysis to calculate the implied fair value of goodwill in the same manner as if the reporting unit was being acquired in a business acquisition. If the implied fair value of goodwill is less than the recorded goodwill, an impairment charge is recorded in operations for the difference.
							The Company estimates the fair value of each reporting unit using a combination of the income approach and the market approach. The income approach incorporates the use of a discounted cash flow method in which the estimated future cash flows and terminal values for each reporting unit are discounted to a present value using a discount rate. Cash flow projections are based on management's estimates of economic and market conditions, which drive key assumptions of revenue growth rates, operating margins, capital expenditures and working capital requirements. The discount rate in turn is based on the specific risk characteristics of each reporting unit, the weighted-average cost of capital and its underlying forecasts. The market approach estimates fair value by applying performance-metric multiples to the reporting unit's prior and expected operating performance. The multiples are derived from comparable publicly traded companies that have operating and investment characteristics similar to the reporting unit. If the fair value of the reporting unit derived using the income approach is significantly different from the fair value estimate using the market approach, the Company reevaluates its assumptions used in the two models. The fair values determined by the market approach and income approach, as described above, are weighted to determine the fair value for each reporting unit. The weighted values assigned to each reporting unit are driven by two primary factors: 1) the number of comparable publicly traded companies used in the market approach, and 2) the similarity of the operating and investment characteristics of the reporting units to the comparable publicly traded companies used in the market approach.
							In order to assess the reasonableness of the calculated reporting unit fair values, the Company also compares the sum of all of its reporting units’ fair values to the Company's market capitalization (per-share stock price multiplied by the number of shares outstanding) and calculates an implied control premium (the excess of the sum of the reporting units’ fair values over the market capitalization). The Company evaluates the reasonableness of the control premium by comparing it to control premiums of recent comparable transactions. If the implied control premium is not reasonable in light of these recent transactions, the Company reevaluates its fair value estimates of the reporting units by adjusting the discount rates and/or other assumptions. As a result, when CSC’s stock price is low, this reevaluation can result in lower estimated fair values of the reporting units.
							Fair Value
							The Company uses the fair value measurement guidance to value certain of its assets and liabilities. Under this guidance, assets and liabilities are required to be valued based on assumptions used by a market participant, consistent with the following hierarchy of inputs:
							Level 1—	Quoted prices unadjusted for identical assets or liabilities in an active market.
							Level 2—	Inputs other than quoted prices that are observable, either directly or indirectly, for similar assets or liabilities.
							Level 3—	Unobservable inputs that reflect the entity’s own assumptions which market participants would use in pricing the asset or liability.
							The assets and liabilities which are valued using the fair value measurement guidance, on a recurring basis, include the Company’s money market funds and money market deposits, time deposits, short-term investments, pension assets, and foreign currency derivatives comprised of forward and option contracts. The fair value of the forward contracts is based on quoted prices for similar but not identical derivative financial instruments; as such, the inputs are considered Level 2 inputs. Option contracts are valued using inputs which are based on quoted pricing intervals from external valuation models, which do not involve management judgment and as such, these inputs are considered Level 2 inputs. Certain pension assets are valued using model based pricing methods that use observable market data; as such these inputs are considered Level 2 inputs. There were no significant assets or liabilities measured at fair value on a recurring basis using significant unobservable (Level 3) inputs.
							Certain assets and liabilities are measured at fair value on a non-recurring basis. These include acquired assets and liabilities in a business combination, equity method investments, asset retirement obligations, long-lived assets and goodwill, which are recognized at fair value to the extent that they are deemed to be impaired or are classified as long-lived assets held to be disposed of by sale. The fair value in these instances is determined using Level 3 inputs.
							Receivables
							Receivables consist of amounts billed and currently due from customers, amounts earned but unbilled (including contracts measured under the percentage-of-completion method of accounting), amounts retained by the customer until the completion of a specified contract, completion of U.S. federal government audit activities audit activities, negotiation of contract modification, and claims.
							Allowances for uncollectible billed trade receivables are estimated based on a combination of write-off history, aging analysis and any specific known collectability issues. Unbilled amounts under contracts in progress that are recoverable do not have an allowance for credit losses. Adjustments to unbilled amounts under contracts in progress related to credit quality, should they occur, would be recorded as a reduction of revenue.
							Impairment of Long-Lived Assets
							Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be recoverable. Recoverability of long-lived assets or groups of assets is assessed based on a comparison of the carrying amount to the estimated future net cash flows. If estimated future undiscounted net cash flows are less than the carrying amount, an expense is recorded in the amount, if any, required to reduce the carrying amount to fair value. Fair value is determined based on a discounted cash flow approach or, when available and appropriate, to comparable market values. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.
							Income Taxes
							Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities. The Company maintains valuation allowances when, based on the weight of available evidence, it is more likely than not that all or a portion of a deferred tax asset will not be realized. Changes in valuation allowances from period to period are included in the Company’s tax provision in the period of change. In determining whether a valuation allowance is warranted, the Company takes into account such factors as prior earnings history, expected future earnings, carryback and carryforward periods, and tax strategies that could potentially enhance the likelihood of realization of a deferred tax asset.
							The Company recognizes uncertain tax positions in the financial statements when it is more likely than not that the tax position will be sustained upon examination. Uncertain tax positions are measured based on the probabilities that the uncertain tax position will be realized upon final settlement (see Note 10).
							Cash and Cash Equivalents
							The Company considers investments with an original maturity of three months or less to be cash equivalents. The Company’s cash equivalents consist of time deposits, money market funds and money market deposit accounts with a number of institutions that have high credit ratings.
							Cash Flows
							Cash payments for interest on indebtedness and cash payments for taxes on income are as follows:
									Twelve Months Ended
							(Amounts in millions)		March 29, 2013				March 30, 2012			April 1, 2011
							Interest		$	186			$	177		$	173
							Taxes on income, net of refunds		214				139			219
							Non-cash investing activities include the following:
									Twelve Months Ended
							(Amounts in millions)		March 29, 2013				March 30, 2012			April 1, 2011
							Capital expenditures in accounts payable and accrued expenses		$	32			$	47		$	122
							Capital expenditures through capital lease obligations		181				270			289
							Assets acquired under long-term financing		26				32			115
							Non-cash financing activities include common stock dividends of $30 million which are declared but not yet paid as of March 29, 2013.
							Foreign Currency
							The Company has determined that, generally, the local currency of its foreign affiliates is their functional currency. Accordingly, the assets and liabilities of the foreign affiliates are translated from their respective functional currency to U.S. dollars using year-end exchange rates, income and expense accounts are translated at the average rates in effect during the year, and equity accounts are translated at historical rates. The resulting translation adjustment is reported in the Statement of Other Comprehensive Income and recorded as part of accumulated other comprehensive income (AOCI). The amount of currency translation adjustment included in AOCI, for the years ended March 29, 2013, March 30, 2012 and April 1, 2011, was $(83) million (net of taxes of $12 million), $(124) million (net of taxes of $1 million) and $261 million (net of taxes of $3 million), respectively.
							To manage the exposure to movements in foreign currency exchange rates, the Company uses foreign currency forward contracts and option contracts (see Note 7). The use of these derivative instruments is intended to offset, to the extent possible, the gains and losses from remeasurement of the Company’s foreign currency denominated monetary assets and liabilities. Gains and losses from remeasurement of the Company’s foreign currency denominated assets and liabilities, and remeasurement and settlement of the related foreign currency derivatives are recorded in Other (income) expense.
							Earnings (Loss) Per Share
							Basic earnings (loss) per common share (EPS) are computed using the weighted average number of common shares outstanding during the period. Diluted EPS reflect the incremental shares issuable upon the assumed exercise of stock options and equity awards.
									Twelve Months Ended
							(Amounts in millions, except per-share data)		March 29, 2013				March 30, 2012			April 1, 2011

							Shares for diluted earnings (loss) per share		$	155.557			$	155.012		$	156.605
							Earnings (loss) per share – basic and diluted:

							Discontinued operations		3.09				1.07			0.8
							Total		$	6.18			$	(27.37	)	$	4.73
							The computation of diluted EPS does not include stock options which are antidilutive, as their exercise price exceeded the average market price of the Company’s common stock. The number of shares related to such stock options were 14,755,024, 17,592,316, and 9,431,834, for the years ended March 29, 2013, March 30, 2012, and April 1, 2011, respectively. In addition, the computation of diluted EPS for the year ended March 30, 2012, excluded options to purchase 442,228 shares of common stock and 1,064,959 RSUs whose effect, if included, would have been anti-dilutive due to the Company’s net loss.
							New Accounting Standards
							During fiscal year 2013, the Company adopted the following recent Accounting Standard Updates (ASUs):
							On June 16, 2011, the FASB issued ASU 2011-05, “Presentation of Comprehensive Income,” which revises the manner in which entities present comprehensive income in their financial statements. The new guidance removes the presentation options in ASC 220 "Comprehensive Income" and requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. The Company adopted the amendments in this update effective at the beginning of fiscal 2013 using the two-statement approach.
							On September 15, 2011, the FASB issued ASU 2011-08, “Testing Goodwill for Impairment,” which revises guidance on testing goodwill for impairment. The amendments in the ASU allow an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If an entity determines that it is not more likely than not, then performing the two-step impairment is unnecessary. However, if the entity concludes that fair value is more likely than not less than carrying value, then it is required to perform the first step of the two-step impairment test and calculate the fair value of the reporting unit to compare with the carrying value of the reporting unit as described in ASC 350-20-35-4. The entity may bypass the initial qualitative assessment for any reporting unit in any period and proceed directly to the first step of the two-step impairment test. The entity may resume performing the qualitative assessment in any subsequent period. The Company adopted the amendments in the update effective at the beginning of fiscal 2013 on a prospective basis, and they did not have a material effect on CSC's Consolidated Financial Statements.
							In December 2011, the FASB issued ASU 2011-11, “Disclosures about Offsetting Assets and Liabilities,” which was subsequently amended in January 2013 when the FASB issued ASU 2013-01 “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities”. Together, these ASUs provide guidance on disclosure of information pertaining to the offsetting (netting) of assets and liabilities in the financial statements. The amendments in these ASUs affect all entities that have financial instruments and derivative instruments that either (1) offset in accordance with either ASC 210-20-45 or ASC 815-10-45, or (2) are subject to an enforceable master netting arrangement or similar agreement. ASU 2011-11 amends the existing disclosure requirements on offsetting in ASC 210-20-50 by requiring disclosures relating to gross amounts of recognized assets and liabilities, the amounts that are offset, net amounts presented in the balance sheet, and amounts subject to an enforceable master netting arrangement or similar agreement. The amendments in these updates became effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The Company adopted the amendments in this update during the first quarter of fiscal 2014 and included additional disclosures in the Consolidated Condensed Financial Statements (see Note 7).
							Standards Issued But Not Yet Effective
							The following ASUs were recently issued but have not yet been adopted by CSC:
							On February 6, 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income”, which requires entities to report the effect of significant reclassifications out of AOCI on the respective line items in net income unless the amounts are not reclassified in their entirety to net income. For amounts that are not required to be reclassified in their entirety to net income in the same reporting period, entities are required to cross-reference other disclosures that provide additional detail about those amounts. The amendments are effective prospectively for fiscal years and interim periods within those years, beginning after December 15, 2012. The Company is currently evaluating the impact of the adoption of these amendments.
							In February 2013, the FASB issued ASU No. 2013-04, "Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date” which requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in this ASU also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. CSC will be required to adopt the amendments in this ASU beginning in fiscal 2015. We are currently evaluating the impact that the adoption may have on CSC's Consolidated Financial Statements.
							In March 2013, the FASB issued ASU No. 2013-05, Foreign Currency Matters (Topic 830): “Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity” which resolves the diversity in practice about whether Subtopic 810-10, Consolidation - Overall, or Subtopic 830-30, Foreign Currency Matters - Translation of Financial Statements, applies to the release of the cumulative translation adjustment into net income when a parent either sells a part of or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. In addition, the amendments resolve the diversity in practice for the treatment of business combinations achieved in stages (i.e. step acquisitions) involving a foreign entity. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. CSC will be required to adopt the amendments in this ASU beginning in fiscal 2015. The adoption of the amendments of these updates is not expected to have a material effect on CSC's Consolidated Financial Statements.

	Recent Accounting Pronouncements
	New Accounting Standards
	During the first quarter of fiscal year 2014, the Company adopted the following Accounting Standard Updates (ASUs):
	In July 2013, the FASB issued ASU 2013-11, “Presentation of an Unrecognized Tax Benefits When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists”, which requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The amendments in this update are consistent with CSC's existing practices and adoption of the amendments in this update did not have a material effect on CSC's Consolidated Condensed Financial Statements.
	In February 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (AOCI),” which requires entities to disclose the effect of significant reclassifications out of AOCI on the respective line items in net income unless the amounts are not reclassified in their entirety to net income. For amounts that are not required to be reclassified in their entirety to net income in the same reporting period, entities are required to cross-reference other disclosures that provide additional detail about those amounts. The amendments are effective for fiscal years and interim periods within those years, beginning after December 15, 2012. The Company adopted the amendments of this update during the first quarter of fiscal 2014 and included additional disclosures in the Consolidated Condensed Financial Statements (see Note 11).
	In December 2011, the FASB issued ASU 2011-11, “Disclosures about Offsetting Assets and Liabilities,” which was subsequently amended in January 2013 when the FASB issued ASU 2013-01 “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities”. Together, these ASUs provide guidance on disclosure of information pertaining to the offsetting (netting) of assets and liabilities in the financial statements. The amendments in these ASUs affect all entities that have financial instruments and derivative instruments that either (1) offset in accordance with either ASC 210-20-45 or ASC 815-10-45, or (2) are subject to an enforceable master netting arrangement or similar agreement. ASU 2011-11 amends the existing disclosure requirements on offsetting in ASC 210-20-50 by requiring disclosures relating to gross amounts of recognized assets and liabilities, the amounts that are offset, net amounts presented in the balance sheet, and amounts subject to an enforceable master netting arrangement or similar agreement. The amendments in these updates became effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods.

	Standards Issued But Not Yet Effective
	The following ASUs were recently issued but have not yet been adopted by CSC:
	In February 2013, the FASB issued ASU No. 2013-04, "Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date.” This ASU requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in this ASU also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. For CSC, the amendments of this ASU will be effective in fiscal 2015. The Company is in the process of evaluating the impact of adopting the ASU on CSC's Consolidated Condensed Financial Statements.
	In March 2013, the FASB issued ASU No. 2013-05, Foreign Currency Matters (Topic 830): “Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity,” which resolves the diversity in practice about whether Subtopic 810-10, Consolidation - Overall, or Subtopic 830-30, Foreign Currency Matters - Translation of Financial Statements, applies to the release of the cumulative translation adjustment into net income when a parent either sells a part of or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity.

Use of Estimates	'
	Use of Estimates
	GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. These estimates are based on management’s best knowledge of historical experience, current events, and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from these estimates. Amounts subject to significant judgment and estimates include, but are not limited to, contracts accounted for using the percentage-of-completion method, cash flows used in the evaluation of impairment of goodwill and other long-lived assets, intangible assets, certain deferred costs, collectability of receivables, reserves for uncertain tax benefits, valuation allowances on deferred tax assets, loss accruals for litigation, pension related liabilities, inputs used for computing stock-based compensation and the fair value of derivative instruments.
Revenue Recognition	'
	Revenue Recognition
	The Company's primary service offerings are information technology (IT) outsourcing, and both IT and other professional services. Revenues are recognized when persuasive evidence of an arrangement exists, services or products have been provided to the client, the sales price is fixed or determinable, and collectability is reasonably assured. For non-software arrangements that include multiple-elements, revenue recognition involves the identification of separate units of accounting after consideration of combining and/or segmenting contracts and allocation of the arrangement consideration to the units of accounting on the basis of their relative selling price. Revenue under such contracts is recognized based upon the levels of services delivered in the periods in which they are provided. Upfront fees for the contract set-up activities are deferred and recognized ratably over the period of performance. Costs are expensed as incurred except for direct and incremental set-up costs that are capitalized and amortized over the life of the agreement (see Outsourcing Contract Costs below). See the section below regarding software transactions that include multiple elements.
	The Company provides these services under time and materials, cost-reimbursable, unit-price and fixed-price contracts, the revenue for which is recognized in the following manner:
	Time and materials contracts - Revenue is recorded at agreed-upon billing rates at the time services are provided.
	Cost-reimbursable contracts - Revenue is recorded at the time costs are incurred and associated fees are recognized when probable and estimable by applying an estimated factor to costs as incurred, such factor being determined by the contract provisions and prior experience.
	Unit-price contracts - Revenue is recognized on unit-price contracts based on unit metrics multiplied by the agreed upon contract unit price or when services are delivered.
	Fixed-price contracts - For certain fixed-price contracts, revenue is recognized under the percentage-of-completion method as described below; these include certain software development projects, all long-term construction-type contracts, and certain fixed-price arrangements with the U.S. federal government. For other fixed-price contracts, revenue is recognized based on the proportion of the services delivered to date as a percentage of the total services to deliver over the contract term. If output or input measures are not available or cannot be reasonably estimated, revenues are recognized ratably over the contract term.
	Under the percentage-of-completion method, progress towards completion is measured based on either achievement of specified contract milestones, costs incurred as a proportion of estimated total costs, or other measures of progress when available. Profit in a given period is reported at the estimated profit margin to be achieved on the overall contract. This method can result in the recognition of unbilled receivables, the deferral of costs as work in process, or deferral of profit on these contracts. Contracts that require estimates at completion using the percentage-of-completion method accounted for approximately 17.9% of the Company's revenues for fiscal 2013. Management regularly reviews project profitability and underlying estimates. Revisions to the estimates at completion are reflected in results of operations as a change in accounting estimate in the period in which the facts that give rise to the revision become known by management. Provisions for estimated losses at completion, if any, are recognized in the period in which the loss becomes evident. The provision includes estimated costs in excess of estimated revenue and any profit margin previously recognized.
	Multiple-element software sales - For multiple-element arrangements that involve the sale of CSC proprietary software, post contract customer support, and other software-related services, vendor-specific objective evidence (VSOE) of fair value is required to allocate and recognize revenue for each element. VSOE of fair value is determined based on the price charged where each deliverable is sold separately. In situations where VSOE of fair value exists for all undelivered elements but not a delivered element (typically the software license element), the residual method is used to allocate revenue to the undelivered elements equal to their VSOE value with the remainder allocated to the delivered element. If significant customization is required, and VSOE is available to support accounting for the software as a separate unit of account, software revenue is recognized as the related software customization services are performed in accordance with the percentage-of-completion method described above. In situations where VSOE of fair value does not exist for all of the undelivered software-related elements, revenue is deferred until only one undelivered element remains and then recognized following the pattern of delivery of the final undelivered element.
Depreciation and Amortization	'
	Depreciation and Amortization
	The Company’s depreciation and amortization policies are as follows:
	Property and Equipment:
	Buildings	Up to 40 years
	Computers and related equipment	3 to 5 years
	Furniture and other equipment	2 to 15 years
	Leasehold improvements	Shorter of lease term or useful life
	Software	2 to 10 years
	Outsourcing contract costs	Contract life, excluding option years
	Customer related intangibles	Expected customer service life
	Acquired contract related intangibles	Contract life and first contract renewal, where applicable
	The cost of property and equipment, less applicable residual values, is depreciated using predominately the straight-line method. Depreciation commences when the specific asset is complete, installed and ready for normal use. Depreciation expense for fiscal years 2013, 2012, and 2011 was $709 million, $754 million, and $685 million, respectively.
	Software and outsourcing contract costs are amortized using predominately the straight-line method. Acquired contract related and customer related intangible assets are amortized in proportion to the estimated undiscounted cash flows projected over the estimated life of the asset or on a straight-line basis if such cash flows cannot be reliably estimated.
Software Development Costs	'
	Software Development Costs
	The Company capitalizes costs incurred to develop commercial software products after technological feasibility has been established. Costs incurred to establish technological feasibility are charged to expense as incurred. Enhancements to software products are capitalized where such enhancements extend the life or significantly expand the marketability of the products. Amortization of capitalized software development costs is determined separately for each software product. Annual amortization expense is calculated based on the greater of (a) the ratio of current gross revenues for each product to the total of current anticipated future gross revenues for the product or (b) the straight-line method over the estimated economic life of the product.
	Unamortized capitalized software costs associated with commercial software products are regularly evaluated for impairment on a product-by-product basis by a comparison of the unamortized balance to the product’s net realizable value. The net realizable value is the estimated future gross revenues from that product reduced by the related estimated future costs. When the unamortized balance exceeds the net realizable value, the unamortized balance is written down to the net realizable value and an impairment charge is recorded.
	The Company capitalizes costs incurred to develop internal-use computer software. Internal and external costs incurred in connection with development of upgrades or enhancements that result in additional functionality are also capitalized. These capitalized costs are amortized on a straight-line basis over the estimated useful life of the software. Purchased software is capitalized and amortized over the estimated useful life of the software.
Outsourcing Contract Costs	'
	Outsourcing Contract Costs
	Costs on outsourcing contracts, including costs incurred for bid and proposal activities, are generally expensed as incurred. However, certain costs incurred upon initiation of an outsourcing contract are deferred and expensed over the contract life. These costs represent incremental external costs or certain specific internal costs that are directly related to the contract acquisition or transition activities. Such capitalized costs can be separated into two principal categories: contract acquisition costs and transition/set-up costs. The primary types of costs that may be capitalized include labor and related fringe benefits, subcontractor costs, travel costs, and premiums on asset purchases.
	Premiums are amounts paid to customers in excess of the fair market value of assets acquired. Fixed assets acquired in connection with outsourcing transactions are capitalized at fair value and depreciated consistent with the fixed asset policies described above. Premiums paid are capitalized as outsourcing contract costs and amortized over the contract life. The amortization of outsourcing contract cost premiums is accounted for as a reduction in revenue. The second principal category of capitalized outsourcing costs is transition/set-up costs. Such costs are primarily associated with the installation of systems and processes and are amortized over the contract life.
	In the event indications exist that an outsourcing contract cost balance related to a particular contract may be impaired, undiscounted estimated cash flows of the contract are projected over its remaining term and compared to the associated long-lived asset group including the unamortized outsourcing contract cost balance. If the projected cash flows are not adequate to recover the unamortized cost balance of the asset group, the balance would be adjusted based on the fair value of the long-lived assets group in the period such a determination is made. The primary indicator used to determine when impairment testing should be performed is when a contract is materially underperforming, or is expected to materially underperform in the future, as compared to the original bid model or subsequent annual budgets.
	Terminations of outsourcing contracts, including transfer of assets either back to the customer or to another IT provider, prior to the end of their committed contract terms, are infrequent due to the complex transition of personnel, assets, methodologies, and processes involved with outsourcing transactions. In the event of an early termination, the Company and the customer, pursuant to certain contractual provisions, engage in discussions to determine the recovery of unamortized contract costs, lost profits, transfer of personnel, rights to implemented systems and processes, as well as other matters.
Stock-Based Compensation	'
	Stock-Based Compensation
	The Company provides different forms of stock-based compensation to its employees and nonemployee directors. For awards settled in shares, the Company recognizes compensation expense based on the grant-date fair value net of estimated forfeitures. For awards settled in cash, the Company recognizes compensation expense based on the fair value at each reporting date net of estimated forfeitures. The Company recognized stock-based compensation expense for fiscal 2013, fiscal 2012, and fiscal 2011 as follows:
			Twelve Months Ended
	(Amounts in millions)		March 29, 2013				March 30, 2012			April 1, 2011
	Cost of services		$	22			$	15		$	12
	Selling, general and administrative		27				21			44
	Total		$	49			$	36		$	56
	Total, net of tax		$	31			$	23		$	35
	The Company’s overall stock-based compensation granting practice has not changed year-over-year, except that with fiscal 2012's long-term incentive program, service-based restricted stock units (RSUs) and performance-based RSUs represent a larger portion of total stock-based compensation awards than in the past.
	The increase in fiscal 2013 stock-based compensation expense was primarily due to performance-based RSUs granted in fiscal 2013 that increased the expense by $15 million. This increase was partially offset by a $3 million reduction of expense as a result of adjustments for expected achievement of the specified performance criteria for performance-based RSUs granted in previous fiscal years. Fiscal 2012 stock-based compensation expense included a $12 million reduction to expense for expected achievement of the specified performance criteria for performance-based RSUs granted in previous fiscal years. There were no such adjustments in fiscal 2011.
	The Company periodically evaluates its significant assumptions used in the fair value calculation. Beginning in fiscal 2011, the Company modified certain underlying assumptions in the fair value calculations, which did not have a material impact on the fair value calculations, as described below.
	The Company uses the Black-Scholes-Merton model in determining the fair value of options granted. The expected term is calculated based on the Company’s historical experience with respect to its stock plan activity in combination with an estimate of when vested and unexercised option shares will be exercised. The Company uses separate assumptions for the expected term of options granted based on two separate job tier classifications which had distinct historical exercise behavior. This resulted in separate fair value calculations by job tier. The risk-free interest rate is based on the zero coupon interest rate of U.S. government issued Treasury strips with a period commensurate with the expected term of the options. In determining the overall risk-free interest rate for fiscal 2013, a range of interest rates from 0.82% to 1.44% was applied depending on the expected life of the grant. The Company continued to base expected volatility on a blended approach using an equal weighting of implied volatility and historical volatility. However, beginning with the first quarter of fiscal 2011, the historical volatility calculation was based on the Company’s six-year and seven-year historical daily closing price, rather than the ten-year historical used in prior periods, in order to bring this factor more closely into alignment with the expected terms of the stock options. The range of volatility used for fiscal 2013 was 32% to 38%. The dividend yield assumption was added concurrent with the introduction of a cash dividend in fiscal 2011 and is based on the respective fiscal year dividend payouts. Forfeitures are estimated based on historical experience and adjustments are made annually to reflect actual forfeiture experience.
	The weighted average grant date fair values of stock options granted during fiscal 2013, fiscal 2012, and fiscal 2011 were $7.37, $10.17, and $12.95 per share, respectively. In calculating the compensation expense for its stock incentive plans, the Company used the following weighted average assumptions:
		Fiscal Year
		2013			2012			2011
	Risk-free interest rate	1.15	%		1.8	%		2.37	%
	Expected volatility	36	%		31	%		28	%
	Expected term (in years)	6.59			6.11			5.85
	Dividend yield	2.86	%		1.79	%		1.17	%
	During fiscal 2013, fiscal 2012, and fiscal 2011, the Company's actual tax benefit realized for tax deductions from exercising stock options was of $9 million, $7 million, and $11 million, respectively, and an excess tax benefit of $3 million, $2 million, and $6 million, respectively, related to all of its stock incentive plans.
Acquisition Accounting and Goodwill	'
	Acquisition Accounting and Goodwill
	Under acquisition accounting, the purchase price is allocated to the underlying tangible and intangible assets acquired and liabilities assumed based upon their respective fair market values, with the excess recorded as goodwill. Acquisition-related costs are expensed in the periods in which the costs are incurred, and the results of operations of acquired businesses are included in the Consolidated Financial Statements from the acquisition date.
	The Company tests goodwill for impairment on an annual basis, as of the first day of the second fiscal quarter, and between annual tests if circumstances change, of if an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. A significant amount of judgment is involved in determining whether an event indicating impairment has occurred between annual testing dates. Such indicators may include: a significant decline in expected future cash flows; a significant adverse change in legal factors or in the business climate; unanticipated competition; the disposal of a significant component of a reporting unit; and the testing for recoverability of a significant asset group within a reporting unit.
	The goodwill impairment test initially involves the assessment of qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is not more likely than not, then the subsequent two-step process is not required, although the Company has the option to bypass this initial qualitative assessment and proceed directly to step one of the two-step process. If the Company determines that it is more likely than not, then it proceeds with the subsequent two-step goodwill impairment testing process. The first step is to compare each reporting unit’s fair value to its carrying value. If the reporting unit’s fair value exceeds its carrying value, no further procedures are required. However, if a reporting unit’s fair value is less than its carrying value, an impairment of goodwill may exist, requiring a second step to measure the amount of impairment loss. In the second step, the reporting unit’s fair value is allocated to all of the assets and liabilities of the reporting unit, including any unrecognized intangible assets, in a hypothetical analysis to calculate the implied fair value of goodwill in the same manner as if the reporting unit was being acquired in a business acquisition. If the implied fair value of goodwill is less than the recorded goodwill, an impairment charge is recorded in operations for the difference.
	The Company estimates the fair value of each reporting unit using a combination of the income approach and the market approach. The income approach incorporates the use of a discounted cash flow method in which the estimated future cash flows and terminal values for each reporting unit are discounted to a present value using a discount rate. Cash flow projections are based on management's estimates of economic and market conditions, which drive key assumptions of revenue growth rates, operating margins, capital expenditures and working capital requirements. The discount rate in turn is based on the specific risk characteristics of each reporting unit, the weighted-average cost of capital and its underlying forecasts. The market approach estimates fair value by applying performance-metric multiples to the reporting unit's prior and expected operating performance. The multiples are derived from comparable publicly traded companies that have operating and investment characteristics similar to the reporting unit. If the fair value of the reporting unit derived using the income approach is significantly different from the fair value estimate using the market approach, the Company reevaluates its assumptions used in the two models. The fair values determined by the market approach and income approach, as described above, are weighted to determine the fair value for each reporting unit. The weighted values assigned to each reporting unit are driven by two primary factors: 1) the number of comparable publicly traded companies used in the market approach, and 2) the similarity of the operating and investment characteristics of the reporting units to the comparable publicly traded companies used in the market approach.
Fair Value	'
	Fair Value
	The Company uses the fair value measurement guidance to value certain of its assets and liabilities. Under this guidance, assets and liabilities are required to be valued based on assumptions used by a market participant, consistent with the following hierarchy of inputs:
	Level 1—	Quoted prices unadjusted for identical assets or liabilities in an active market.
	Level 2—	Inputs other than quoted prices that are observable, either directly or indirectly, for similar assets or liabilities.
	Level 3—	Unobservable inputs that reflect the entity’s own assumptions which market participants would use in pricing the asset or liability.
	The assets and liabilities which are valued using the fair value measurement guidance, on a recurring basis, include the Company’s money market funds and money market deposits, time deposits, short-term investments, pension assets, and foreign currency derivatives comprised of forward and option contracts. The fair value of the forward contracts is based on quoted prices for similar but not identical derivative financial instruments; as such, the inputs are considered Level 2 inputs. Option contracts are valued using inputs which are based on quoted pricing intervals from external valuation models, which do not involve management judgment and as such, these inputs are considered Level 2 inputs. Certain pension assets are valued using model based pricing methods that use observable market data; as such these inputs are considered Level 2 inputs. There were no significant assets or liabilities measured at fair value on a recurring basis using significant unobservable (Level 3) inputs.
	Certain assets and liabilities are measured at fair value on a non-recurring basis. These include acquired assets and liabilities in a business combination, equity method investments, asset retirement obligations, long-lived assets and goodwill, which are recognized at fair value to the extent that they are deemed to be impaired or are classified as long-lived assets held to be disposed of by sale. The fair value in these instances is determined using Level 3 inputs.
Receivables	'
	Receivables
	Receivables consist of amounts billed and currently due from customers, amounts earned but unbilled (including contracts measured under the percentage-of-completion method of accounting), amounts retained by the customer until the completion of a specified contract, completion of U.S. federal government audit activities audit activities, negotiation of contract modification, and claims.
	Allowances for uncollectible billed trade receivables are estimated based on a combination of write-off history, aging analysis and any specific known collectability issues. Unbilled amounts under contracts in progress that are recoverable do not have an allowance for credit losses. Adjustments to unbilled amounts under contracts in progress related to credit quality, should they occur, would be recorded as a reduction of revenue.
Valuation of Long-Lived Assets	'
	Impairment of Long-Lived Assets
	Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be recoverable. Recoverability of long-lived assets or groups of assets is assessed based on a comparison of the carrying amount to the estimated future net cash flows. If estimated future undiscounted net cash flows are less than the carrying amount, an expense is recorded in the amount, if any, required to reduce the carrying amount to fair value. Fair value is determined based on a discounted cash flow approach or, when available and appropriate, to comparable market values. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.
Income Taxes	'
	Income Taxes
	Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities. The Company maintains valuation allowances when, based on the weight of available evidence, it is more likely than not that all or a portion of a deferred tax asset will not be realized. Changes in valuation allowances from period to period are included in the Company’s tax provision in the period of change. In determining whether a valuation allowance is warranted, the Company takes into account such factors as prior earnings history, expected future earnings, carryback and carryforward periods, and tax strategies that could potentially enhance the likelihood of realization of a deferred tax asset.
	The Company recognizes uncertain tax positions in the financial statements when it is more likely than not that the tax position will be sustained upon examination. Uncertain tax positions are measured based on the probabilities that the uncertain tax position will be realized upon final settlement (see Note 10).
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	The Company considers investments with an original maturity of three months or less to be cash equivalents. The Company’s cash equivalents consist of time deposits, money market funds and money market deposit accounts with a number of institutions that have high credit ratings.
Foreign Currency	'
	Foreign Currency
	The Company has determined that, generally, the local currency of its foreign affiliates is their functional currency. Accordingly, the assets and liabilities of the foreign affiliates are translated from their respective functional currency to U.S. dollars using year-end exchange rates, income and expense accounts are translated at the average rates in effect during the year, and equity accounts are translated at historical rates. The resulting translation adjustment is reported in the Statement of Other Comprehensive Income and recorded as part of accumulated other comprehensive income (AOCI). The amount of currency translation adjustment included in AOCI, for the years ended March 29, 2013, March 30, 2012 and April 1, 2011, was $(83) million (net of taxes of $12 million), $(124) million (net of taxes of $1 million) and $261 million (net of taxes of $3 million), respectively.
	To manage the exposure to movements in foreign currency exchange rates, the Company uses foreign currency forward contracts and option contracts (see Note 7). The use of these derivative instruments is intended to offset, to the extent possible, the gains and losses from remeasurement of the Company’s foreign currency denominated monetary assets and liabilities. Gains and losses from remeasurement of the Company’s foreign currency denominated assets and liabilities, and remeasurement and settlement of the related foreign currency derivatives are recorded in Other (income) expense.
Earnings per Share	'
	Earnings (Loss) Per Share
	Basic earnings (loss) per common share (EPS) are computed using the weighted average number of common shares outstanding during the period. Diluted EPS reflect the incremental shares issuable upon the assumed exercise of stock options and equity awards.

	Discontinued operations		3.09				1.07			0.8
	Total		$	6.18			$	(27.37	)	$	4.73
	The computation of diluted EPS does not include stock options which are antidilutive, as their exercise price exceeded the average market price of the Company’s common stock. The number of shares related to such stock options were 14,755,024, 17,592,316, and 9,431,834, for the years ended March 29, 2013, March 30, 2012, and April 1, 2011, respectively. In addition, the computation of diluted EPS for the year ended March 30, 2012, excluded options to purchase 442,228 shares of common stock and 1,064,959 RSUs whose effect, if included, would have been anti-dilutive due to the Company’s net loss.
New Accounting Pronouncements and Standards Not Yet Adopted	'
	New Accounting Standards
	During fiscal year 2013, the Company adopted the following recent Accounting Standard Updates (ASUs):
	On June 16, 2011, the FASB issued ASU 2011-05, “Presentation of Comprehensive Income,” which revises the manner in which entities present comprehensive income in their financial statements. The new guidance removes the presentation options in ASC 220 "Comprehensive Income" and requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. The Company adopted the amendments in this update effective at the beginning of fiscal 2013 using the two-statement approach.
	On September 15, 2011, the FASB issued ASU 2011-08, “Testing Goodwill for Impairment,” which revises guidance on testing goodwill for impairment. The amendments in the ASU allow an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If an entity determines that it is not more likely than not, then performing the two-step impairment is unnecessary. However, if the entity concludes that fair value is more likely than not less than carrying value, then it is required to perform the first step of the two-step impairment test and calculate the fair value of the reporting unit to compare with the carrying value of the reporting unit as described in ASC 350-20-35-4. The entity may bypass the initial qualitative assessment for any reporting unit in any period and proceed directly to the first step of the two-step impairment test. The entity may resume performing the qualitative assessment in any subsequent period. The Company adopted the amendments in the update effective at the beginning of fiscal 2013 on a prospective basis, and they did not have a material effect on CSC's Consolidated Financial Statements.
	In December 2011, the FASB issued ASU 2011-11, “Disclosures about Offsetting Assets and Liabilities,” which was subsequently amended in January 2013 when the FASB issued ASU 2013-01 “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities”. Together, these ASUs provide guidance on disclosure of information pertaining to the offsetting (netting) of assets and liabilities in the financial statements. The amendments in these ASUs affect all entities that have financial instruments and derivative instruments that either (1) offset in accordance with either ASC 210-20-45 or ASC 815-10-45, or (2) are subject to an enforceable master netting arrangement or similar agreement. ASU 2011-11 amends the existing disclosure requirements on offsetting in ASC 210-20-50 by requiring disclosures relating to gross amounts of recognized assets and liabilities, the amounts that are offset, net amounts presented in the balance sheet, and amounts subject to an enforceable master netting arrangement or similar agreement. The amendments in these updates became effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The Company adopted the amendments in this update during the first quarter of fiscal 2014 and included additional disclosures in the Consolidated Condensed Financial Statements (see Note 7).
	Standards Issued But Not Yet Effective
	The following ASUs were recently issued but have not yet been adopted by CSC:
	On February 6, 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income”, which requires entities to report the effect of significant reclassifications out of AOCI on the respective line items in net income unless the amounts are not reclassified in their entirety to net income. For amounts that are not required to be reclassified in their entirety to net income in the same reporting period, entities are required to cross-reference other disclosures that provide additional detail about those amounts. The amendments are effective prospectively for fiscal years and interim periods within those years, beginning after December 15, 2012. The Company is currently evaluating the impact of the adoption of these amendments.
	In February 2013, the FASB issued ASU No. 2013-04, "Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date” which requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in this ASU also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. CSC will be required to adopt the amendments in this ASU beginning in fiscal 2015. We are currently evaluating the impact that the adoption may have on CSC's Consolidated Financial Statements.
	In March 2013, the FASB issued ASU No. 2013-05, Foreign Currency Matters (Topic 830): “Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity” which resolves the diversity in practice about whether Subtopic 810-10, Consolidation - Overall, or Subtopic 830-30, Foreign Currency Matters - Translation of Financial Statements, applies to the release of the cumulative translation adjustment into net income when a parent either sells a part of or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. In addition, the amendments resolve the diversity in practice for the treatment of business combinations achieved in stages (i.e. step acquisitions) involving a foreign entity. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. CSC will be required to adopt the amendments in this ASU beginning in fiscal 2015. The adoption of the amendments of these updates is not expected to have a material effect on CSC's Consolidated Financial Statements.
