	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 and nine months ended December 27, 2013 and December 28, 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 unaudited Consolidated Condensed Financial Statements and the accompanying notes. It is recommended that these unaudited 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).
	With 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 14). All prior period segment disclosures have been recast to reflect the Company's change in reportable segments.
	The Consolidated Condensed Statements of Operations, of Comprehensive Income (Loss) and of Changes in Equity, along with the related notes, for the quarter and nine months ended December 28, 2012, have been recast from those presented in the previously filed Form 10-Q to reflect discontinued operations of two businesses sold in fiscal 2014, a business that CSC has committed to a plan to sell in fiscal 2014 and one business sold in fiscal 2013 (see Note 3).
	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 December 27, 2013 and December 28, 2012 include both continuing and discontinued operations.
	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 and nine months ended December 27, 2013 and December 28, 2012.
		Quarter Ended						Nine Months Ended
	(Amounts in millions, except per-share data)	December 27, 2013			December 28, 2012			December 27, 2013			December 28, 2012
	Gross favorable	$	26		$	26		$	101		$	89
	Gross unfavorable	(12		)	(44		)	(38		)	(107		)
	Total net adjustments, before taxes and non-controlling interest	$	14		$	(18	)	$	63		$	(18	)
	Impact on diluted EPS from continuing operations	$	0.06		$	(0.18	)	$	0.26		$	(0.27	)
	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 $48 million as of both December 27, 2013 and March 29, 2013.
	Depreciation expense was $165 million and $498 million for the quarter and nine months ended December 27, 2013, respectively, and $174 million and $533 million for the quarter and nine months ended December 28, 2012, respectively.

Recent Accounting Pronouncements [Abstract]	'
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	New Accounting Standards
	During the first nine months of fiscal 2014, the Company adopted the following Accounting Standard Updates (ASUs):
	In January 2014, the FASB issued ASU No. 2014-05, "Service Concession Arrangements (Topic 853) (a consensus of the FASB Emerging Issues Task Force).” The objective of the amendments in this Update is to provide guidance on the accounting for service concession arrangements. A service concession arrangement is an arrangement between a public-sector entity grantor and an operating entity under which the operating entity operates the grantor’s infrastructure (for example, airports, roads, and bridges). The operating entity also may provide the construction, upgrading, or maintenance services of the grantor’s infrastructure. This ASU specifies that an operating entity should not account for a service concession arrangement, within the scope of this ASU, as a lease in accordance with Topic 840, Leases. The amendments also specify that the infrastructure used in a service concession arrangement should not be recognized as property, plant, and equipment of the operating entity. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. For CSC, the amendments of this ASU will be effective in fiscal 2016. The Company is in the process of evaluating the impact of adopting the ASU on CSC's unaudited Consolidated Condensed Financial Statements.
	In July 2013, the FASB issued ASU 2013-11, “Presentation of an Unrecognized Tax Benefit 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 unaudited 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 unaudited Consolidated Condensed Financial Statements (see Note 12).
	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 unaudited 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:
	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 unaudited 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. 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. 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 unaudited Consolidated Condensed Financial Statements.

	ServiceMesh Acquisition
	On November 15, 2013, CSC acquired ServiceMesh Inc. (ServiceMesh), a privately held enterprise cloud management company headquartered in Santa Monica, California, with operations in the United States, Australia and the United Kingdom, for total estimated purchase consideration of $300 million. The acquisition enhances CSC’s ability to help its clients migrate their applications into cloud computing environments, and automate the deployment and management of enterprise applications and platforms across private, public and hybrid cloud environments.
	The purchase consideration included cash of $163 million paid at closing for outstanding equity, vested stock options, and debt of $10 million that was repaid at the acquisition date and the preliminarily estimated fair value of contingent consideration of $137 million (see Note 6), which the Company expects to pay during the fourth quarter of fiscal 2014. The estimated amount of contingent consideration was based on a contractually defined multiple of ServiceMesh’s revenues during a specified period, as well as other considerations. Should the final amount of contingent consideration be different from the preliminary estimate of $137 million, the difference will be recorded as an other income or expense item in the future periods. The range of possible outcomes for the final fair value of the contingent consideration is $0 to $137 million. The acquisition was funded from CSC's existing cash balances. The Company incurred transaction costs of $4 million associated with this acquisition. These costs were expensed and are included within selling, general and administrative expenses.
	The results of ServiceMesh are included in the Company's consolidated financial statements from the date of acquisition, within its GIS segment.
	The preliminary allocation of the purchase price to the assets acquired and liabilities assumed is presented below:
	(Amounts in millions)	Estimated Fair Value
	Accounts receivable and other current assets	$	3
	Deferred tax assets	23
	Intangible asset - developed technology	94
	Intangible assets - customer relationships and trade names	10
	Property and equipment and other noncurrent assets	2
	Trade payables, accrued expenses and deferred revenue	(4		)
	Deferred tax liabilities	(39		)
	Total identifiable net assets acquired	89
	Goodwill	211
	Total estimated consideration	$	300
	The Company’s purchase price allocation for ServiceMesh is preliminary and subject to revision as additional information related to the fair value of assets and liabilities becomes available.
	The amortizable lives associated with the intangible assets acquired are as follows:
	Developed technology        9 years

	The goodwill recognized in the acquisition is attributable to the intellectual capital, the acquired assembled work force, and expected cost synergies, none of which qualify for recognition as a separate intangible asset. The goodwill arising from the acquisition was preliminarily allocated to the Company's reportable segments based on the relative fair value of the expected incremental cash flows that the acquisition is expected to provide to each reporting unit. Goodwill was allocated as follows: GBS: $31 million, GIS: $139 million, and NPS: $41 million. The goodwill is not expected to be deductible for tax purposes.
	Infochimps Acquisition
	On August 5, 2013, CSC acquired Infochimps, Inc. (Infochimps), a privately held company, in an all-cash transaction for $27 million. The acquisition complements CSC’s existing Big Data business by providing a flexible, scalable, platform-as-a-service offering. The purchase price has been allocated, on a preliminary basis, to net assets acquired and liabilities assumed based on estimates of fair value at the date of acquisition, resulting in recording current and other long-term assets of $2 million, current and long-term liabilities of $2 million, and goodwill of $27 million. The goodwill is associated with the Company's GBS segment and is not tax-deductible.
	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 to enhance CSC's capabilities in Big Data processing and analytics. 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.
	The financial results of the fiscal 2014 and fiscal 2013 acquired businesses were included in the Company’s unaudited Consolidated Condensed Financial Statements from their respective dates of acquisition. Pro forma financial information for these acquisitions was not presented as they were neither individually nor in the aggregate material to CSC’s consolidated results.
	Discontinued Operations
	Fiscal 2014 Divestitures
	In September 2013, CSC committed to a plan to sell a small software business, which is a part of the GBS segment's Industry Software & Solutions group. The Company is actively marketing this business for sale and expects the divestiture to be completed within the next nine months. As a result, the historical results of this business have been presented as discontinued operations in the Company's unaudited Consolidated Condensed Statement of Operations, and its assets and liabilities are classified as held-for-sale. The assets and liabilities classified as held-for-sale as of December 27, 2013 included: current assets of $23 million, property and equipment and other long-term assets of $30 million, current liabilities of $36 million, and long-term liabilities of $17 million. No goodwill was allocated to this business.
	On July 19, 2013, CSC completed the sale of its base operations, aviation and ranges services business unit, Applied Technology Division (ATD) within its NPS Segment, to a strategic investor for cash consideration of approximately $178 million plus a net working capital adjustment receivable of $6 million. This disposition reflects CSC's ongoing service portfolio optimization initiative, and the results of ATD are presented as discontinued operations in the unaudited Consolidated Condensed Statements of Operations. The pre-tax gain on disposal was $67 million, representing the excess of the sale price over the carrying value of the net assets of the divested business, less transaction costs of $3 million. The divested assets and liabilities included: current assets of $142 million (including cash of $7 million), goodwill of $41 million, other long-term assets of $11 million, current liabilities of $66 million, long-term liabilities of $35 million, and accumulated other comprehensive loss, net of noncontrolling interests of $21 million.
	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 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 recorded 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 unaudited Consolidated Condensed Statements of Operations as discontinued operations.
	Fiscal 2013 Divestitures
	During fiscal 2013, CSC completed the divestiture of three businesses within its GBS Segment: its U.S.-based credit services business, its Italian consulting and system integration business, and an enterprise systems integration business with operations in Malaysia and Singapore. These divestitures reflected the Company's ongoing service portfolio optimization initiative to focus on next-generation technology services and are presented in the Company's unaudited Consolidated Condensed Statements of Operations as discontinued operations.
	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 received another $13 million in the third quarter of fiscal 2014 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) in fiscal 2013. The Company received $6 million during the second quarter of fiscal 2014 from the buyer for a purchase price adjustment.
	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, an additional $2 million in pre-tax gain was recorded during the first quarter of fiscal 2014.
	The fiscal 2013 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.
	A summary of the results of the discontinued operations is presented below:
		Quarter Ended					Nine Months Ended

	Income from discontinued operations, net of taxes	$	(5	)	$	399	$	72		$	442
	There was minimal tax on gain on the sale of ATD primarily due to the difference between the amount of the book and tax gains. 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.
	Other Divestiture
	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 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 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 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.

	Investigations and Out of Period Adjustments
	Summary of Audit Committee and SEC Investigations Related to the Out of Period Adjustments
	As previously disclosed, the Company initiated an investigation into out of period adjustments resulting from certain accounting errors in its 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.
	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 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. 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 the Company's 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. As the Company previously disclosed, certain of its non-U.S. employees and certain of its former employees, including certain former executives in the United States, have received Wells notices from the SEC’s Division of Enforcement in connection with its ongoing investigation of the Company. The Company, through outside counsel, has been in discussions with the SEC Enforcement Staff concerning a potential resolution of the investigation involving the Company. However, to date those discussions have not resulted in a resolution. The Company received a Wells notice from the SEC’s Division of Enforcement on December 11, 2013. A Wells notice is not a formal allegation or a finding of wrongdoing; it is a preliminary determination by the SEC Enforcement Staff to recommend that the Commission file a civil enforcement action or administrative proceeding against the recipient. Under SEC procedures, a recipient of a Wells notice has an opportunity to respond in the form of a Wells submission that seeks to persuade the Commission that such an action should not be brought. The Company is availing itself of the Wells process by making a Wells submission to explain its views concerning such matters, which are aided by the Company Audit Committee's independent investigation and certain expert opinions of outside professionals. The Company made such a submission on January 14, 2014. The Company is unable to estimate with confidence or certainty how long the SEC process will last or its ultimate outcome, including whether the Company will reach a settlement with the SEC and, if so, the amount of any related monetary fine and other possible remedies. 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.
	Out of Period Adjustments Financial Impact Summary
	The rollover impact on income (loss) from continuing operations before taxes of the recorded out of period adjustments in the first nine months of fiscal 2014, fiscal 2013 and fiscal 2012 is attributable to the following prior fiscal years:
			Increase/(Decrease)
	(Amounts in millions)		Fiscal 2012 Adjustments			Fiscal 2013 Adjustments			First Nine Months Fiscal 2014 Adjustments			Total Adjustments
	Fiscal 2014		$	—		$	—		$	(3	)	$	(3	)
	Fiscal 2013		—			6			(1		)	5
	Fiscal 2012		79			7			—			86
	Prior fiscal years (unaudited)		(79		)	(13		)	4			(88		)
	See Note 14 for a summary of the effect of the pre-tax out of period adjustments on the Company's segment results for the quarter and nine months ended December 27, 2013 and December 28, 2012, respectively.
	Fiscal 2014 Adjustments
	During the third quarter and through the first nine months of fiscal 2014, the Company recorded net pre-tax adjustments increasing income from continuing operations before taxes by $5 million and $3 million, respectively, that should have been recorded in prior fiscal years. The $5 million of pre-tax out of period adjustments consists of a $7 million increase to revenue (due to a $6 million adjustment to recognize revenue on previously delivered software products and services and a $1 million adjustment to recognize revenue on previously delivered outsourcing services), partially offset by a $2 million charge to cost of services (COS) (consisting of a $5 million increase to COS relating to previously delivered software products and services, offset by a $3 million decrease to COS as a result of a margin correction on long-term contracts accounted for under the percentage-of-completion method).
	Adjustments, net of tax, during the third quarter of fiscal 2014 that should have been recorded in prior fiscal years increased income from continuing operations by $4 million. Adjustments, net of tax, during the first nine months of fiscal 2014 that should have been recorded in prior fiscal years decreased income from continuing operations by $18 million. The difference between the pre-tax and after tax impact is attributable to the tax effect of the net pre-tax adjustments, and net out of period adjustments to tax expense that should have been recorded in prior fiscal years. The tax effect on the net pre-tax adjustments for the third quarter was a $1 million increase to tax expense and for the first nine months of fiscal 2014 was a $9 million increase in tax expense. The tax effect on the pre-tax adjustments for the first nine months of fiscal 2014 resulted in a disproportionate increase in tax expense due to taxes on increases in income in taxable jurisdictions, and absence of tax benefits on decreases in income in jurisdictions with net operating loss carry forwards. The out of period adjustments to tax expense for the third quarter and first nine months of fiscal 2014 resulted in no change and an increase to income tax expense of $12 million, respectively. The out of period adjustments to tax expense for the nine months ended December 27, 2013, consist primarily of a $10 million increase in liabilities for uncertain tax positions associated with a tax restructuring of one of the Company's operating subsidiaries recorded during the second quarter of fiscal 2014.
	In addition, during the third quarter of fiscal 2014, the Company recorded $7 million of pre-tax adjustments increasing income from continuing operations before taxes that should have been recorded in the first six months of fiscal 2014. The $7 million of pre-tax out of period adjustments consists primarily of a reduction of $7 million to COS (attributable to a $5 million reduction to accrued expenses, a $3 million reduction of costs related to a reversal of previously recognized software products and services, a $4 million pension accrual expense reduction, all partially offset by a $3 million reduction of margin on long-term contracts accounted for under the percentage-of-completion method, and a $2 million adjustment to recognize costs on previously delivered software products and services). In addition to the reduction to COS, a net $1 million adjustment was recorded to increase revenue on previously delivered software products and services and a $1 million increase in selling, general and administrative (SG&A) expenses was recognized related to a write-off of prepaid facility charges. Adjustments, net of tax, during the third quarter of fiscal 2014 increased income from continuing operations by $9 million that should have been recorded in the first six months of fiscal 2014. The difference between the pre-tax and after tax impact is attributable to the tax effect of the net pre-tax adjustments.
	During the second quarter of fiscal 2014, the Company recorded net pre-tax adjustments decreasing income from continuing operations before taxes by $11 million that should have been recorded in prior fiscal years. The $11 million of pre-tax out of period adjustments consists of a $9 million reversal of revenue (due to deferral of revenue for undelivered elements on software contracts lacking vendor specific objective evidence and margin corrections on contracts under percentage of completion accounting), a $1 million charge to cost of sales for reversal of previously deferred costs and a $1 million charge to SG&A expense reversing excess capitalization associated with internal systems development. Adjustments, net of tax, during the second quarter of fiscal 2014 that should have been recorded in prior fiscal years decreased income from continuing operations by $20 million. The difference between the pre-tax and after tax impact is attributable to the tax effect of the net pre-tax adjustments, and net out of period adjustments to tax expense that should have been recorded in prior fiscal years. The tax effect on the net pre-tax adjustments for the second quarter of fiscal 2014 was negligible. The out of period adjustments to tax expense for the second quarter of fiscal 2014 resulted in an increase to income tax expense of $9 million. The out of period adjustments to tax expense consist primarily of a $10 million increase in liabilities for uncertain tax positions associated with a tax restructuring of one of the Company's operating subsidiaries.
	In addition, during the second quarter of fiscal 2014, the Company recorded $17 million of pre-tax adjustments decreasing income from continuing operations before taxes that should have been recorded in the first quarter of fiscal 2014. The $17 million of pre-tax out of period adjustments consists of (1) a $13 million charge to cost of sales consisting of $6 million in adjustments to prepaid and accrued balances, a $4 million reversal of previously deferred costs and a $3 million reduction in work in process due to margin corrections on contracts under percentage-of-completion accounting; (2) a $3 million charge to SG&A expense primarily due to reversal of excess capitalization associated with internal systems development, partially offset by other adjustments; and (3) a $1 million charge to depreciation expense to correct the useful life for certain leasehold improvements. Adjustments, net of tax, during the second quarter of fiscal 2014 decreased income from continuing operations by $11 million that should have been recorded in the first quarter of fiscal 2014. The difference between the pre-tax and after tax impact is attributable to the tax effect of the net pre-tax adjustments.
	During the first quarter of fiscal 2014, the Company identified and recorded net pre-tax 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 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 increasing income from continuing operations before taxes by $8 million resulting from the correction of payroll expenses within its GBS segment; and
	•	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.
	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 between the pre-tax and after tax impact 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.
	The impact of out of period adjustments recorded during fiscal 2014 on select line items of the Consolidated Condensed Statements of Operations for the quarter and nine months ended December 27, 2013, respectively, using the rollover method, is shown below:

The out of period adjustments impacting income from continuing operations before taxes recorded by the Company in the nine months ended December 27, 2013 are related to the following consolidated balance sheet line items:
•	Accounts receivable ($1 million decrease);
•	Prepaid expenses and other current assets ($3 million increase);
•	Property and equipment ($1 million decrease);
•	Software ($1 million decrease);
•	Other assets ($1 million decrease);
•	Accrued payroll and related costs ($8 million decrease)
•	Deferred revenue ($21 million increase); and
•	Accrued expenses and other current liabilities ($17 million decrease).
The Company has determined that the impact of the consolidated out of period adjustments recorded in fiscal 2014 is immaterial to the consolidated results, financial position and cash flows for the third quarter and first nine months of fiscal 2014 and prior years. Consequently, the cumulative effect of these adjustments was recorded during fiscal 2014.
Fiscal 2013 Adjustments
As previously reported, during the third quarter and through the first nine months of fiscal 2013, the Company identified and recorded net pre-tax adjustments decreasing income from continuing operations before taxes by $3 million and increasing income from continuing operations before taxes by $4 million, respectively, that should have been recorded in prior fiscal years ($3 million and $13 million, net of tax and including discrete tax benefits). In addition, during the third quarter of fiscal 2013, the Company recorded $3 million of net pre-tax adjustments increasing income from continuing operations before taxes and $2 million of net pre-tax adjustments decreasing income from continuing operations before taxes that should have been recorded in the first and second quarters of fiscal 2013, respectively.
The $3 million pre-tax out of period adjustments recorded in the third quarter of fiscal 2013 that should have been recorded in prior fiscal years, resulted primarily from correcting the useful lives of property and equipment that were inconsistent with established CSC accounting conventions. This error occurred in connection with a GIS contract in France.
During the third quarter of fiscal 2013, the Company identified additional prior period errors related to the use of the percentage-of-completion accounting method on its NHS contract. Such errors, which were self-correcting, have no impact on income from continuing operations before taxes for fiscal 2013. Had such adjustments been recorded in fiscal 2012, income from continuing operations before taxes would have increased by $22 million. For fiscal 2011, income from continuing operations before taxes would have decreased by $3 million. For fiscal 2010, there would have been no impact on income from continuing operations before taxes. For fiscal 2009 and prior periods, income from continuing operations before taxes would have decreased by $19 million.
During the second quarter of fiscal 2013, the Company identified and recorded net pre-tax adjustments increasing income from continuing operations before taxes by $8 million that should have been recorded in prior fiscal years ($10 million, net of tax). In addition, during the second quarter of fiscal 2013, the Company recorded $2 million of net pre-tax adjustments increasing income from continuing operations before taxes that should have been recorded in the first quarter of fiscal 2013 and had no impact on prior fiscal years.
The $8 million pre-tax out of period adjustments recorded in the second quarter of fiscal 2013 consisted primarily of $9 million of net adjustments increasing income from continuing operations before taxes related to the Company's investigation of the use of percentage-of-completion accounting on the NHS contract. Such adjustments result primarily from accounting errors identified by the Company related to costs incurred under the NHS contract.
Based on information then known by the Company, the out of period adjustments recorded in the first quarter of fiscal 2013 were comprised of $6 million of net adjustments reducing income from continuing operations before taxes identified by the Company late in the fiscal 2012 closing process, which due to the immaterial amounts involved, were not included in the Company's consolidated fiscal 2012 financial statements. Also in the first quarter of fiscal 2013, the Company identified and recorded $5 million of net pre-tax adjustments increasing income from continuing operations that should have been recorded in prior fiscal years. The $5 million of net pre-tax adjustments consisted primarily of charges related to a $2 million software revenue recognition correction and a $2 million adjustment to prepaid expenses offset by credits primarily related to corrections of $10 million to reduce accrued expenses related to the restructuring costs recorded by the Company in fiscal 2012.
The Company also recorded a $2 million tax benefit in the first quarter of fiscal 2013 related to prior periods. The $2 million tax benefit was attributable to the adjustment of the deferred tax liability related to intellectual property assets.
During periods subsequent to December 28, 2012, the Company recorded out of period adjustments primarily in its GBS and GIS segments that should have been recorded in the first nine months of fiscal 2013. Had such adjustments been recorded in the appropriate period, income from continuing operations before taxes for the third quarter and first nine months of fiscal 2013 would have decreased by $2 million and increased by $2 million, respectively.
The impact of out of period adjustments recorded during fiscal 2013, and the first nine months of fiscal 2014, on select line items of the Consolidated Condensed Statements of Operations for the quarter and nine months ended December 28, 2012, respectively, using the rollover method, is shown below:

The out of period adjustments impacting income from continuing operations before taxes recorded by the Company in the nine months ended December 28, 2012 are related to the following consolidated balance sheet line items:
•	Accounts receivable ($5 million decrease);
•	Prepaid expenses and other current assets ($6 million increase);
•	Property and equipment ($7 million decrease);
•	Outsourcing contract costs ($1 million increase);
•	Other assets ($4 million increase);
•	Accrued payroll and related costs ($1 million decrease);
•	Deferred revenue ($4 million increase); and
•	Accrued expenses and other current liabilities ($6 million decrease).
The Company determined that the impact of the consolidated out of period adjustments recorded in the third quarter of fiscal 2013 was immaterial to the consolidated results, financial position and cash flows for the third quarter of fiscal 2013 and prior years. Consequently, the cumulative effect of these adjustments was recorded during fiscal 2013.

	In connection with the acquisition of ServiceMesh, the Company recorded contingent consideration of $137 million at the acquisition date fair value (see Note 3). The fair value of this short-term liability, at December 27, 2013, is based on unobservable inputs, or Level 3 assumptions. The significant inputs used in the valuation of the contingent consideration include ServiceMesh's revenues during the earn-out measurement period and a multiple of these revenues, in accordance with the purchase agreement. Further, the determination of revenues earned during the measurement period is based on U.S. GAAP as laid out in ASC 605, Revenue Recognition.
	The sensitivity of the value of the contingent consideration is based on the revenues earned during the measurement period, per U.S. GAAP, and consequently the fair value of the contingent consideration can range between $0 - $137 million. During the third quarter of fiscal 2014, there were no changes to this liability due to payments or revaluation and therefore no gains or losses recognized in earnings related to this liability.
	The Company's money market funds, money market deposit accounts and time deposits are reported in cash and cash equivalents; short-term investments and foreign currency derivative instruments are included in prepaid expenses and other current assets; interest rate swap derivative assets are included in other assets; foreign currency derivative liabilities and contingent consideration are included in accrued expenses and other current liabilities and interest rate swap derivative liabilities are included in other long-term liabilities. 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 and no transfers into or out of Level 3.
	Derivative assets and liabilities include foreign currency forward and option contracts and interest rate swap contracts (see Note 7). 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 interest rate swaps is estimated based on valuation models that use interest rate yield curves as inputs. The inputs used to estimate the fair value of the Company's derivatives are classified as Level 2.
	Fair value measurements on a non-recurring basis
	Assets and liabilities measured at fair value on a non-recurring 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 nine months ended December 27, 2013 and December 28, 2012.
	Financial Instruments not measured at fair value
	The carrying amounts of the Company’s financial instruments with short-term maturities are deemed to approximate their market values. The carrying amount of the Company’s long-term debt, excluding capital leases was $1,856 million and $2,119 million, and the estimated fair value was $2,021 million and $2,324 million, as of December 27, 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.
	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.
	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 December 27, 2013, the Company had $15 million of accounts receivable, $10 million of related allowance for doubtful accounts, $1 million of other assets, and $4 million of accounts payable with customers involved in bankruptcy proceedings.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Foreign Currency Derivative Instruments	'
	Derivative Instruments
	The Company is exposed to market risks associated with movements in foreign currency exchange rates and changes in interest rates. Changes in foreign currency exchange rates can impact the Company's foreign currency denominated monetary assets and liabilities, whereas changes in benchmark interest rates can impact the fair value of the Company's term notes. The Company uses derivative instruments to mitigate the impact of these market risks, and not for trading or any speculative purpose.
	Foreign Currency Derivatives
	As a global organization, the Company enters into contracts denominated in foreign currencies. By generally matching revenues, costs and borrowings to the same currency, the Company is able to substantially mitigate foreign currency risk to earnings. In other instances, the Company manages the exposure to fluctuations in foreign currencies by using short-term option contracts to economically hedge certain revenues denominated in non-functional currencies, and short-term foreign currency forward contracts to economically hedge certain foreign currency denominated assets and liabilities, including intercompany accounts and loans. For accounting purposes, these foreign currency option and forward contracts are not designated as hedges, as defined under ASC 815, “Derivatives and Hedging,” and all changes in their fair value are reported in current period earnings within the other income (expense) line of the consolidated condensed statement of operations.
	The notional amount of the foreign currency forward contracts outstanding as of December 27, 2013 and March 29, 2013 was $1,526 million and $993 million, respectively. The notional amount of option contracts outstanding as of December 27, 2013 and March 29, 2013 was $210 million and $744 million, respectively.
	The estimated fair values of the foreign currency derivative assets and liabilities were $1 million and $16 million, respectively, as of December 27, 2013, and $5 million and $11 million, respectively, as of March 29, 2013 (see Note 6).
	The Company is subject to counterparty credit risk in connection with its foreign currency derivative instruments. To mitigate this risk, the Company enters into forward and option contracts from several financial institutions and regularly reviews its credit exposure and the creditworthiness of the counterparties. As of December 27, 2013, there were five 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 $1 million.
	It is the Company's policy to not offset derivative assets and liabilities despite the existence of enforceable master netting arrangements with some of its counterparties. The following table provides information about the potential effect of such netting arrangements on the Company's derivative instruments:
			Fair Value as of
			December 27, 2013				March 29, 2013
	(Amounts in millions)		Assets		Liabilities		Assets		Liabilities
	Gross amount of derivative instruments recognized in consolidated condensed balance sheets		$	1	$	16	$	5	$	11
	Gross amounts not offset in the consolidated condensed balance sheets (1)		—		—		2		2
	Net amount		$	1	$	16	$	3	$	9
	-1	These amounts represent the fair value of derivative instruments subject to enforceable master netting arrangements that the Company has elected to not offset. The Company's derivative contracts do not require it to hold or post financial collateral.
	Interest Rate Swaps
	Pursuant to its interest rate and risk management strategy, during the second quarter of fiscal 2014, the Company entered into multiple interest rate swap transactions to hedge the fair value of $275 million of the Company's 4.45% term notes, due 2022, which effectively converted the debt into floating interest rate debt.
	For accounting purposes, these interest rate swap transactions were designated as fair value hedges and qualified for short-cut method of hedge accounting, as defined under ASC 815, “Derivatives and Hedging.” Accordingly, changes in the fair values of the interest rate swaps were reported in earnings and fully offset changes in the fair value of the underlying debt (see Note 8). The cash flows associated with the interest rate swaps are reported in net cash provided by (used in) operating activities on the Consolidated Condensed Statements of Cash Flows.
	The estimated fair value of the interest rate swaps was under $1 million as of December 27, 2013 and this amount is reported as a derivative liability included within the other liabilities line on the Company's Consolidated Condensed Balance Sheets (see Note 6). The change in fair value of interest rate swaps was $6 million for the quarter ended December 27, 2013.
	Consistent with the Company's counterparty risk management strategy, the Company contracted with several financial institutions to execute the swap transactions.

	Total long-term debt	$	2,184	$	2,498
	Term loan facility
	During the third quarter of fiscal 2014, the Company's subsidiary, Computer Sciences Holdings (UK) Ltd., entered into a £250 million or $409 million (at the December 27, 2013 exchange rates; $408 million on the Consolidated Statement of Cash Flow due to the impact of movement in foreign currency exchange rates) short-term note payable, due December 2014, with a financial institution. The note bears interest at a variable rate based on LIBOR plus a margin of 17 basis points (bps) and is payable quarterly. The note is guaranteed by the Company, and financial covenants associated with the note are the same as those associated with the Company's $2.5 billion revolving credit facility, as mentioned below. The Company was in compliance with all covenants as of December 27, 2013.
	During the third quarter of fiscal 2014, the Company repaid the $250 million term loan, due September 2016 (2016 Term Loan), from its cash balances on hand. The Company recorded $1 million as additional interest expense to write-off previously deferred debt issuances expenses associated with the 2016 Term Loan.
	Term note exchanges
	During the third quarter of fiscal 2014, the Company entered into multiple exchange agreements to exchange an aggregate of $40 million original principal amount of its 6.50% term notes due 2018 for an aggregate of $47 million original principal amount of its 4.45% term notes, due 2022. During the second quarter of fiscal 2014, the Company entered into an exchange agreement with a noteholder to exchange $21 million original principal amount of its 6.50% term notes due 2018 for $25 million original principal amount of its 4.45% term notes due 2022. These term note exchanges were accounted for as a debt modification and as a result, the difference between the original principal value of term notes exchanged was accounted for as additional debt discount, which along with the existing unamortized discount and deferred financing costs, will be amortized to interest expense over the term of the 4.45% term notes, using the effective interest method.
	Interest rate swaps
	As disclosed in Note 7, during the second quarter of fiscal 2014, the Company entered into multiple interest rate swap transactions to hedge the fair value of $275 million of its 4.45% term notes, due 2022, which effectively converted the debt into floating interest rate debt. Under the terms of the swap transactions, the Company will receive semi-annual interest payments at the coupon rate of 4.45% and will pay monthly interest at the one month LIBOR rate, plus a weighted average contractual margin. The Company designated these interest rate swaps as fair value hedges and is accounting for them in accordance with the shortcut method under ASC Topic 815 (See Note 7). The change in the fair value of the interest rate swaps from inception to December 27, 2013 was under $1 million. The carrying value of the 4.45% term notes due 2022, recorded as long-term debt within the Consolidated Condensed Balance Sheets, was decreased by this amount.
	Revolving credit facility
	During the third quarter of fiscal 2014, the Company amended its unsecured $1.5 billion revolving credit facility by expanding its borrowing capacity to $2.5 billion and extending its maturity to January 15, 2019. The terms of the amended $2.5 billion facility allow for borrowings by both CSC and certain of its international subsidiaries within a $2 billion sub-limit for borrowings denominated in U.S. dollar, Euros and Pound Sterling, and a $0.5 billion sub-limit for borrowings denominated in U.S. dollar, Euros, Pounds Sterling, Japanese Yen, Australian Dollar and Singapore Dollar. The amended credit facility also provides, on an uncommitted basis, that the aggregate amount of the facility may be increased to up to $3 billion. The amended facility has a lower interest margin on drawn amounts and provides for lower commitment fees on undrawn amounts than the prior credit facility. The Company incurred costs of $4 million related to amendment and expansion of the credit facility. These costs have been deferred and will be amortized over the term of the facility. There were no borrowings outstanding against the $2.5 billion credit facility at December 27, 2013, and the Company was in compliance with all the financial covenants at December 27, 2013.

	The Company contributed $18 million and $72 million to the defined benefit pension plans during the quarter and nine months ended December 27, 2013, respectively. In aggregate, the Company expects to contribute approximately $87 million during fiscal 2014. Additional contributions may be required to meet funding levels as required by Section 430 of the Internal Revenue Code, as amended by the Pension Protection Act of 2006, the amount of which will be determined based upon actuarial valuations that will be performed in the fourth quarter of fiscal 2014.
	On July 19, 2013, CSC completed the sale of ATD (see Note 3), which had a pension and retiree medical plan. The plans were remeasured as of the date of the sale that resulted in settlement costs totaling $4 million that was recorded as part of gain on sale of ATD, and a reduction to long-term liabilities of $28 million. The net periodic pension cost, not including any settlement gain or loss, for the nine months ended December 27, 2013 and December 28, 2012 was $4 million and $6 million.
	On December 20, 2013 two U.K. pension plans were remeasured due to a plan amendment arising from a change in the index used to determine the level of pension increases, from the Retail Prices Index (RPI) to the Consumer Prices Index (CPI). A weighted average discount rate of 4.65% was used to remeasure the plans; an increase from 4.31% in the prior fiscal year. As a result of the remeasurement, the pension benefit obligation decreased by $443 million and the average funded status was 108%.
	During the third quarter of fiscal 2014, a pension plan in Switzerland recognized a settlement loss of $3 million as a result of restructuring activities. The plan was remeasured on September 30, 2013 using a discount rate of 2.3%, an increase from 2.05% in the prior fiscal year, which resulted in a reduction to the pension benefit obligation of $43 million, improving the plan's funded status.
	During the second quarter of fiscal 2013, a pension plan in Norway was amended to change the index used to benchmark pension payment increases. The plan was remeasured at July 1, 2012, the effective date of the amendment, resulting in a reduction to the projected benefit obligation by $28 million, improving the plan's funded status. The plan's fiscal 2013 expense was also remeasured for the remaining nine months of the fiscal year using a new discount rate of 4%.
	The components of net periodic benefit cost for other post-retirement benefit plans, reported on a global basis, included the following:
		Quarter Ended

	Income Taxes
	The Company's effective tax rate from continuing operations (ETR) was 31.7% and 31.8% for the quarter and nine months ended December 27, 2013, respectively, and 20.8% and 27.5% for the quarter and nine months ended December 28, 2012, respectively. The following are the primary drivers of the ETR for the nine months ended December 27, 2013 and December 28, 2012. For the tax impact of discontinued operations, see Note 3 to the Consolidated Condensed Financial Statements.
	•	During the third quarter and nine months ended December 27, 2013, the Company recorded an income tax benefit of approximately $5.6 million relating to the settlement of audits for certain of its non-US jurisdictions, which reduced the ETR by 2.5% and 0.9%, respectively.
	•	During the second quarter of fiscal 2014, the Company recorded an income tax expense of $10 million related to the previous restructuring of an operating subsidiary. This expense increased the ETR for the nine months ended December 27, 2013 by 1.5%.
	•	During the third quarter and nine months ended December 28, 2012, there was a decrease in valuation allowances in non-U.S. jurisdictions due to (i) a shift in the global mix of income which impacted the ETR by 7.6% and 3.2%, respectively and (ii) expected capital gains from the sale of certain other assets which impacted the ETR by 6.0% and 2.5%, respectively.
	•	During the second quarter of fiscal 2013, the Company released $6.4 million of its liability for uncertain tax positions related to prior year research and development credits which reduced the ETR for the nine months ended December 28, 2012 by 1.8%.
	There were no material changes to uncertain tax positions in the third 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 fiscal 2014, the IRS indicated they need additional time to complete the examination. Therefore, the Company now expects to reach a resolution no earlier than 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. 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 $8 million, excluding interest, penalties, and tax carryforwards.

	The Company’s overall stock-based compensation granting practice has not changed significantly year over year. The increase in stock-based compensation expense, for both the third quarter and the nine month period ended December 27, 2013, was primarily due to adjustments for actual and expected achievement of the specified performance criteria for certain performance-based RSUs. Stock-based compensation expense for the nine months ended December 27, 2013 and December 28, 2012 included an adjustment of $4 million and $3 million, respectively, to reflect actual forfeiture experience for the prior fiscal years.
	The Company uses the Black-Scholes-Merton model in determining the fair value of stock options granted. The weighted average grant date fair values of stock options granted during the three months ended December 27, 2013 and December 28, 2012 were $16.35 and $7.27 per share, respectively. In calculating the compensation expense for its stock incentive plans, the Company used the following weighted average assumptions:
		Nine Months Ended
		December 27, 2013			December 28, 2012
	Risk-free interest rate	1.97	%		1.14	%
	Expected volatility	34	%		36	%
	Expected term (in years)	6.23			6.59
	Dividend yield	1.52	%		2.88	%
	During the nine months ended December 27, 2013 and December 28, 2012, the Company's actual tax benefit realized for tax deductions from exercising stock options and RSU releases was $16 million and $3 million, respectively, and an excess tax benefit of $5 million and $1 million, respectively, related to all of its stock incentive plans.
	Employee Incentives
	The Company has three stock incentive plans that authorize the issuance of stock options, restricted stock and other stock-based incentives to employees upon terms approved by the Compensation Committee of the Board of Directors. The Company issues authorized but previously unissued shares upon the exercise of stock options, the granting of restricted stock and the settlement of RSUs. As of December 27, 2013, 17,793,692 shares of CSC common stock were available for the grant of future stock options, equity awards or other stock-based incentives to employees under such stock incentive plans.
	Stock Options
	The Company’s standard vesting schedule for stock options is one-third of the total stock option award on each of the first three anniversaries of the grant date. Stock options are generally exercisable for a term of ten years from the grant date. Information concerning stock options granted under the Company's stock incentive plans is as follows:
		As of December 27, 2013
		Number			Weighted				Weighted	Aggregate
		of Option Shares			Average				Average	Intrinsic
					Exercise				Remaining	Value

	Outstanding as of December 27, 2013	12,152,486			44.1				5.57	140
	Vested and expected to vest in the future as of December 27, 2013	11,970,829			44.15				5.52	138
	Exercisable as of December 27, 2013	8,315,470			47.2				4.06	70
	The total intrinsic value of options exercised during the nine months ended December 27, 2013 and December 28, 2012 was $27 million and $1 million, respectively. The cash received from stock options exercised during the nine months ended December 27, 2013 and December 28, 2012 was $112 million and $4 million, respectively.
	As of December 27, 2013, there was $36 million of total unrecognized compensation expense related to unvested stock options, net of expected forfeitures. The cost is expected to be recognized over a weighted-average period of 2.12 years.
	Restricted Stock Units
	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 and dividend equivalents are forfeited.
	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. Beginning 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 settled 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. In the table below, such awards are reflected at the number of shares to be settled upon achievement of target performance measures.
	During the nine months ended December 27, 2013, certain executives were awarded service-based RSUs for which the shares will settle 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 executive's separation of service. For certain executives who joined the company in fiscal year 2013 and after, (i)the awards vest at age 62, or (ii) 50% of the award vests at age 55 with 5 years service with an additional 10% vesting each additional year of service up to ten years of service. Prior to fiscal year 2013, awards vested at age 65 or age 55 with 10 years of service.
	Information concerning RSUs granted under stock incentive plans is as follows:
		As of December 27, 2013
		Number of			Weighted Average
		Shares			Fair Value per share
	Outstanding as of March 29, 2013	2,263,272				$	31.53
	Granted	1,995,451				48.93
	Released/Issued	(387,066	)			32.5
	Canceled/Forfeited	(561,316	)			37.87
	Outstanding as of December 27, 2013	3,310,341				41.06
	As of December 27, 2013, there was $106 million of total unrecognized compensation expense related to unvested RSUs, net of expected forfeitures. The unrecognized compensation expense is expected to be recognized over a weighted-average period of 2.41 years.
	Non-employee Director Incentives
	The Company has two stock incentive plans that authorize the issuance of stock options, restricted stock and other stock-based incentives to nonemployee directors upon terms approved by the Company’s Board of Directors. As of December 27, 2013, 197,400 shares of CSC common stock remained available for grant to non-employee directors as RSUs or other stock-based incentives.
	Generally, RSU awards to non-employee directors vest in full as of the next annual meeting of the Company’s stockholders following the date they are granted and are issued at a price of $0. Information concerning RSUs granted to non-employee directors is as follows:
		As of December 27, 2013
		Number of			Weighted Average
		Shares			Fair Value per share
Outstanding as of March 29, 2013	188,445				$	39.85
Granted	25,000				51.55
Released/Issued	(29,299	)			35.81
Canceled/Forfeited	—				—
Outstanding as of December 27, 2013	184,146				42.07
For awards granted in fiscal 2013 and prior, vested RSUs are automatically settled for shares of CSC common stock and dividend equivalents when the non-employee director ceases to be a director of the Company. The number of shares to be settled is equal to the number of RSUs that are vested at the time the holder ceases to be a director. At the holder’s election, the RSUs may be settled (i) in their entirety, upon the day the holder ceases to be a director, or (ii) in substantially equal amounts upon the first five, ten or fifteen anniversaries of such termination of service. For RSU awards granted in fiscal 2014, RSUs vest and settle at the earlier of (i) the one-year anniversary of the grant date, or (ii) the date of the Company's first Annual Meeting of the Stockholders held after the grant date. Alternatively, settlement of the RSU may be deferred per election of the non-employee director.

	Stock Repurchase Program
	In December 2010, the Company’s Board of Directors approved a share repurchase program authorizing up to $1 billion in share repurchases of the Company’s outstanding common stock. CSC has been implementing the program through purchases in compliance with Securities and Exchange Commission rules, market conditions and applicable federal and state legal requirements. The timing, volume, and nature of share repurchases are at the discretion of management and may be suspended or discontinued at any time. No end date was established for the repurchase program.
	During the third quarter and first nine months of fiscal 2014, 2,405,895 and 7,279,117 shares were purchased, respectively, through open market purchases for an aggregate consideration of $125 million and $354 million, respectively, at a weighted average price of $51.96 and $48.58 per share, respectively. The approximate amount for which shares may yet be purchased under this program at December 27, 2013 is $276 million. The Company paid $22 million during the first quarter of fiscal 2014 for shares purchased during the fourth quarter of fiscal 2013 that had not yet settled in cash by March 29, 2013. This amount is presented as a financing outflow in the unaudited Consolidated Condensed Statement of Cash Flows for the nine months ended December 27, 2013 and was reclassified from operating cash flows during the second quarter.
	During the quarter ended December 28, 2012, the Company repurchased 1,971,200 shares through open market purchases for an aggregate consideration of $77 million, at a weighted average price of $39.04 per share. Of the aggregate consideration of $77 million, $18 million was recorded as an accrued liability for shares purchased but not yet settled in cash by December 28, 2012.
	The shares repurchased under the approved plan are retired immediately and included in the category of authorized but unissued shares. The excess of purchase price over par value of the common shares was allocated between additional paid-in capital and retained earnings.

Segment Information	'
	Segment Information
	During fiscal 2013, the Company undertook numerous organizational and operational changes to align the Company's leadership, assets, and operating model with its strategy of leading the next generation of IT services and solutions. 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, which came into effect at the beginning of fiscal 2014, resulted in a change to the Company's reportable segments for 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. 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:
	•	GBS – The GBS segment comprises three units: Consulting, Industry Software & Solutions, and Applications Services. The Consulting business is a global leader in helping large organizations, public-sector entities, and local businesses innovate, transform, and create sustainable competitive advantage through a combination of industry, business process, technology, systems integration and change management expertise. Industry Software & Solutions is a leader in industry-based software, services, and business process services and outsourcing. Software solutions and process-based intellectual property power mission-critical transaction engines in insurance, banking, healthcare and life sciences. Applications Services optimizes and modernizes clients' application portfolio and information services sourcing strategy, enabling clients to capitalize on emerging services such as cloud, mobility, and big data within new commercial models such as the agile "as a Service - Economy" (aaS).
	•	GIS – GIS provides managed and virtual desktop solutions, mobile device management, unified communications and collaboration services, data center management, compute and managed storage solutions to commercial clients globally. GIS also delivers CSC's next generation Cloud offerings, including secure Infrastructure as a Service (IaaS), private Cloud solutions, CloudMail and Storage as a Service (SaaS). To provide clients with uniquely differentiated offerings and expanded market coverage, GIS also collaborates with a select number of strategic partners. This collaboration helps CSC determine the best technology, road map and opportunities to differentiate solutions, augment capabilities, and jointly deliver impactful solutions. CSC seeks to capitalize on an emerging market trend - to rebundle the IT stack on virtualized infrastructure. GIS offerings are designed for any enterprise - from national, multinational and global enterprises.
	•	NPS – NPS delivers IT, mission, and operations-related services to the Department of Defense, civil agencies of the U.S. federal government, as well as other foreign, state and local government agencies. Commensurate with the Company's strategy, NPS is leveraging CSC's commercial best practices and next-generation technologies to bring scalable and more cost-effective IT solutions to government agencies that are seeking efficiency through innovation. Evolving government priorities such as: 1) IT efficiency, which includes data center consolidation and next generation cloud technologies, 2) cyber security, 3) immigration reform, 4) mission intelligence driven by big data solutions, and 5) health IT and informatics, drive demand for NPS offerings.
	The following table summarizes operating results by reportable segment. Segment results for the quarter and nine months ended December 28, 2012 have been recast to reflect the change in reportable segments. In addition, segment results for the quarter and nine months ended December 28, 2012 have been adjusted from amounts previously reported to reflect discontinued operations (see Note 3).

	* Both the gross goodwill and accumulated impairment losses amounts for the GBS segment have been adjusted for a reduction of $19 million, to reflect the fully impaired goodwill associated with the enterprise systems integration business divested in fiscal 2013.
	As described in Note 14, at the beginning of fiscal 2014, the Company changed its operating model, which resulted in changes to the Company's reportable segments and to its reporting units. Concurrent with the change in the reportable segments, the Company reassigned goodwill among certain of 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 reallocation of goodwill is reflected in the goodwill balances as of March 29, 2013, noted above.
	The additions to goodwill are due to the third quarter acquisition of ServiceMesh and the second quarter acquisition of InfoChimps (see Note 3). The deductions to goodwill are due to the first quarter divestiture of GBS' flood insurance BPO business and the second quarter divestiture of NPS' ATD business (see Note 3). No goodwill was allocated to the software business within GBS that was classified as discontinued operations in the second quarter of fiscal 2014 (see Note 3).
	The foreign currency translation amount reflects the impact of currency movements on non-U.S. dollar-denominated goodwill balances.
	At the end of the third quarter of fiscal 2014, the Company assessed whether there were events or changes in circumstances that would more likely than not reduce the fair value of any of its reporting units below their carrying amounts. There were no such indicators for any of the reporting units. The fair values of all of CSC's reporting units were substantially in excess of their carrying values based on the step one test performed in conjunction with the Company's first quarter fiscal 2014 goodwill reallocation. None of the Company's reporting units were at risk of failing the step one test at that time.

	Restructuring Costs
	The Company recorded $11 million and $26 million of restructuring costs for the quarters ended December 27, 2013 and December 28, 2012, respectively. For the nine months ended December 27, 2013 and December 28, 2012, the Company recorded $33 million and $111 million, respectively. The costs recorded during the quarter and nine months ended December 27, 2013 and the December 28, 2012 were in connection with actions under both the Fiscal 2013 Plan and Fiscal 2012 Plan, as described below.
	Fiscal 2013 Plan
	In September 2012, the Company initiated restructuring actions (the Fiscal 2013 Plan) across its business segments. The objectives of the Fiscal 2013 Plan are to (i) further increase the use of lower cost off-shore resources, (ii) reduce headcount in order to align resources to support business needs, including the assessment of management span of control and layers, and (iii) optimize the use of facilities.
	Actions under the Fiscal 2013 Plan commenced in September 2012 and management expects that further actions will be taken during fiscal 2014, which could result in additional charges.
	The restructuring expense incurred during the third quarter of fiscal 2014 included costs related with voluntary staff terminations in Europe and exit costs related to certain leased facilities in the U.K., Canada and the U.S.
	The composition of the restructuring liability for the Fiscal 2013 Plan as of December 27, 2013 is as follows:
	(Amounts in millions)		Restructuring liability as of March 29, 2013		Costs expensed in fiscal 2014		Less: costs not affecting restructuring liability (1)			Cash paid			Other(3)		Restructuring liability as of December 27, 2013

	(2)	Other direct costs associated with the restructuring program.
	(3)	Foreign currency translation adjustments.
	Fiscal 2012 Plan
	In March 2012, the Company initiated restructuring actions (the Fiscal 2012 Plan) primarily impacting its GIS segment. The objectives of the Fiscal 2012 Plan are to (i) align the Company's workforce across various geographies with business needs, (ii) increase use of lower cost off-shore resources, and (iii) optimize utilization of facilities. Actions under the Fiscal 2012 Plan commenced in March 2012 and were substantially carried out through fiscal 2013. Management expects that further actions will be taken during fiscal 2014, which could result in additional charges.
	The composition of the restructuring liability for the Fiscal 2012 Plan as of December 27, 2013 is as follows:
	(Amounts in millions)		Restructuring liability as of March 29, 2013		Costs expensed in fiscal 2014		Cash paid			Other(1)			Restructuring liability as of December 27, 2013

	Of the total $97 million restructuring liability as of December 27, 2013, $93 million is a short-term liability and is included in accrued expenses and other current liabilities, and $4 million is included in other long-term liabilities.
	The composition of restructuring expenses for the third quarter and first nine months of fiscal 2014 and fiscal 2013 by segment is as follows:

	Contract with the U.K. National Health Service
	Revised Project Agreement
	The Company and the NHS are parties to a contract 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.
	On August 31, 2012, the Company and the NHS entered into a binding interim agreement which was approved by all required U.K. government officials ("interim agreement contract change note" or "IACCN"). The IACCN 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 and provided for a change compensation payment by NHS to the Company on that date in the amount of £10 million ($15 million) net of value added tax in full and final satisfaction of all costs and claims by CSC arising from changes to the Lorenzo software product that the Company delivered up to a certain version of the product. On October 4, 2013, the Company and the NHS finalized a full restatement of the contract through a "revised project agreement" (RPA). The RPA embodies and incorporates the principal terms of the IACCN and such letter agreement, makes certain other changes with respect the Company’s non-Lorenzo product deployments and consolidates the three regional contracts which comprised the Company's NHS contract into a single agreement. The RPA has been approved by all required U.K. government officials. Pursuant to the RPA, the parties have agreed to a mutual release of certain accrued claims under the contract through the date of the RPA, October 4, 2013.
	Principal Components of the IACCN and the RPA
	The key terms first agreed in the IACCN (and now embodied in the RPA) with respect to the delivery of the Lorenzo product and associated services 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 (and as now embodied in the RPA), the parties agreed that the NHS is no longer subject to any trust volume commitment for the Lorenzo product, 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.
	2	The IACCN (and as now embodied in the RPA) created pricing and payment terms for the Lorenzo product and new terms under which trusts in the contract's NME region that choose the Lorenzo product can access central funds for its deployment, subject to business case justification. While the funding is provided by the NHS, there is a far greater degree of interaction with the trusts under the terms agreed in the IACCN (and as now embodied in the RPA), as the Company works with each individual trust to build a business case and seek NHS approval and central funding to proceed.
	3	Under the IACCN (and as now embodied in the RPA), the Lorenzo product was 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. 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.
	4	New trusts taking deployments of the Lorenzo product will receive ongoing managed services from the Company for a period of five years from the date such deployment is complete, provided deployment is complete or substantially complete by July 7, 2016. The services include hosting of the software and trust data at the Company's data center as well as support and maintenance, including regulatory updates and other changes over the term of the contract. 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.
	The IACCN did not materially alter the terms relating to the deployment of non-Lorenzo products. However, the RPA reflects certain terms not included in the IACCN relating to the Company’s continued deployment, hosting and maintenance services for non-Lorenzo products and services as follows:
	1	The RPA provides that the NHS will no longer be subject to commitments to purchase additional volumes of non-Lorenzo products and will instead have a committed repurposed fund of the same value in the approximate amount of £47.5 million ($75 million) as of the October 4, 2013 RPA effective date. The NHS may use the repurposed fund to purchase a wide range of services and solutions from CSC under the RPA other than new deployments of Lorenzo products. Except as noted in point 2 below, the existing estate of deployed non-Lorenzo products are not affected by the RPA.
	2	The RPA also provides that the NHS may, subject to certain notice requirements and to the payment of certain decommissioning fees to CSC, require that certain services be removed, or decommissioned, from the scope of the contract and that the related service charges be adjusted accordingly. The NHS’s right to decommission services does not apply to Lorenzo services deployed after the October 4, 2013 RPA effective date or to ambulance services. The basis for decommissioning shall be either the complete closure of an NHS trust (or other NHS service recipient) or the cessation of relevant clinical services by a trust (or other NHS service recipient) (a “natural decommissioning”), or an NHS trust (or other NHS service recipient) determining that it no longer requires a particular service for any other reason (a “voluntary decommissioning”). The NHS is subject, during the remaining term of the contract, to an aggregate monetary limit on the ability to effect any voluntary decommissionings, which at the October 4, 2013 RPA effective date was approximately £19.6 million ($31 million). The NHS is also subject, during the remaining term of the contract, to aggregate monetary limits on the ability to effect any voluntary decommissionings with respect to individual modules of certain products, which limits at the October 4, 2013 RPA effective date, ranged from approximately £0.2 million to £4.4 million ($0.3 million to $6.9 million) (depending on the affected module in question).
	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 (and as now embodied in the RPA) represented 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 terms of the IACCN (and as now embodied in the RPA) 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. As of December 27, 2013, the amount of deferred costs and deferred revenues was $12 million and $197 million, respectively.

	Commitments
	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 December 27, 2013, the Company had $23 million of outstanding surety bonds and $102 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 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 December 27, 2013, the Company had $86 million of outstanding stand-by letters of credit.
	The following table summarizes the expiration of the Company’s financial guarantees and stand-by letters of credit outstanding as of December 27, 2013:
	(Amounts in millions)	Fiscal 2014		Fiscal 2015		Fiscal 2016 and thereafter		Total

	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.
	Contingencies
	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 amended the terms of the then current contract and formed the basis on which the parties finalized 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. On October 4, 2013, the Company and NHS finalized a full restatement of the contract through a revised project agreement (RPA). The RPA embodies and incorporates the principal terms of the IACCN and such letter agreement, makes certain other changes with respect the Company’s non-Lorenzo product deployments and consolidates the three regional contracts which comprised the Company's NHS contract into a single agreement. See Note 17 for further information relating to the foregoing matters.
	As previously disclosed, 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.
	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 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 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. 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 the Company's 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. As the Company previously disclosed, certain of its non-U.S. employees and certain of its former employees, including certain former executives in the United States, have received Wells notices from the SEC’s Division of Enforcement in connection with its ongoing investigation of the Company. The Company, through outside counsel, has been in discussions with the SEC Enforcement Staff concerning a potential resolution of the investigation involving the Company. However, to date those discussions have not resulted in a resolution. The Company received a Wells notice from the SEC’s Division of Enforcement on December 11, 2013. A Wells notice is not a formal allegation or a finding of wrongdoing; it is a preliminary determination by the SEC Enforcement Staff to recommend that the Commission file a civil enforcement action or administrative proceeding against the recipient. Under SEC procedures, a recipient of a Wells notice has an opportunity to respond in the form of a Wells submission that seeks to persuade the Commission that such an action should not be brought. The Company is availing itself of the Wells process by making a Wells submission to explain its views concerning such matters, which are aided by the Company Audit Committee's independent investigation and certain expert opinions of outside professionals. The Company made such a submission on January 14, 2014. The Company is unable to estimate with confidence or certainty how long the SEC process will last or its ultimate outcome, including whether the Company will reach a settlement with the SEC and, if so, the amount of any related monetary fine and other possible remedies. 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 with confidence or certainty any possible loss or range of loss associated with these matter at this time. See Note 4 for further information.
	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 sought 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.

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 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 sought 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 sought 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. On August 9, 2013, the plaintiff filed an amended complaint, which named as defendants Messrs. Laphen and Mancuso, members of the Company’s Board of Directors and the Company as a nominal defendant. On August 23, 2013, the parties, as well as the parties to the Bainto and Himmel cases, entered into a stipulation of settlement, which, if approved by the court, would require CSC to implement or maintain corporate governance reforms and pay to plaintiffs’ counsel an attorney fee and expense amount of $2 million and would release the claims asserted in the Hung, Bainto, Himmel and Morefield cases. The settlement was subject to approval by the Nevada state court. In accordance with the terms of the stipulation of settlement, on August 28, 2013, the plaintiff filed a motion for nonsuit, which was entered by the Virginia state court on September 11, 2013. On September 27, 2013, the Nevada state court entered an Order Preliminarily Approving Derivative Settlement and Providing for Notice. The Order scheduled a Settlement Hearing for November 6, 2013. On November 6, 2013, the Nevada state court entered a Final Judgment and Order of Dismissal with Prejudice, which, among other things, approved the settlement in all respects.
	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. On August 23, 2013, the parties, as well as the parties to the Hung and Himmel cases, entered into a stipulation of settlement, which, if approved by the court, would require CSC to implement or maintain corporate governance reforms and pay to plaintiffs’ counsel an attorney fee and expense amount of $2 million and would release the claims asserted in the Hung, Bainto, Himmel and Morefield cases. The settlement was subject to approval by the Nevada state court. On September 27, 2013, the Nevada state court entered an Order Preliminarily Approving Derivative Settlement and Providing for Notice. The Order scheduled a Settlement Hearing for November 6, 2013. On November 6, 2013, the Nevada state court entered a Final Judgment and Order of Dismissal with Prejudice, which, among other things, approved the settlement in all respects.
	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 included a claim for unjust enrichment and sought additional injunctive relief. Upon stipulation of the parties, the court consolidated the Bainto case (described 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. On August 23, 2013, the parties, as well as the parties to the Hung and Bainto cases, entered into a stipulation of settlement, which, if approved by the court, would require CSC to implement or maintain corporate governance reforms and pay to plaintiffs’ counsel an attorney fee and expense amount of $2 million and would release the claims asserted in the Hung, Bainto, Himmel and Morefield cases.

On September 27, 2013, the Nevada state court entered an Order Preliminarily Approving Derivative Settlement and Providing for Notice. The Order scheduled a Settlement Hearing for November 6, 2013. On November 6, 2013, the Nevada state court entered a Final Judgment and Order of Dismissal with Prejudice, which, among other things, approved the settlement in all respects.
	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. On August 7, 2013, the court granted the motions to dismiss with prejudice and entered judgment in favor of the defendants. On or about August 26, 2013, Plaintiff filed a Notice of Appeal to the United States Court of Appeals for the Fourth Circuit. On October 6, 2013, the parties reached an agreement to resolve the appeal. Plaintiff agreed to dismiss her appeal upon approval of the settlement in the Hung, Bainto and Himmel matters and agreed that, upon final approval of that settlement, her claims shall be released, fully, finally and forever. CSC agreed to pay to Plaintiff’s counsel an attorney fee and expense amount of $195,000. On November 6, 2013, the Nevada state court entered a Final Judgment and Order of Dismissal with Prejudice, which, among other things, approved the settlement of the Hung, Bainto and Himmel matters in all respects. Plaintiff’s appeal was dismissed on November 8, 2013.
	On March 1, 2012, the Company was competitively awarded the Maryland Medicaid Enterprise Restructuring Project (“MERP”) contract by the State of Maryland (the State) to modernize the Medicaid Management Information System ("MMIS"), a database of Medicaid recipients and providers used to manage Medicaid reimbursement claims. The MERP contract is predominately fixed price. Also, since awarded, federal government-mandated Medicaid information technology standards have been in considerable flux. The State has directed the Company to include additional functionality in the design to incorporate new federal mandates and guidance promulgated after the base scope of the Contract was finalized. Further, the State has declined to approve contract modifications to compensate the Company for the additional work.
	As a result of the State’s refusal to amend the MERP contract and equitably adjust the compensation to be paid to the Company and, in accordance with prescribed State statutes and regulations, the Company timely filed a certified claim with the State in the total estimated amount of approximately $61 million on September 27, 2013 (the Claim). The Company believes it has valid and reasonable factual and legal bases for the Claim and that the circumstances that have led or will lead to the Company’s additional costs set forth in the Claim were unforeseen as of the operative proposal submission dates and are not the result of deficiencies in CSC’s performance. However, the Company’s position is subject to the ongoing evaluation of new facts and information which may come to the Company’s attention should the Claim be denied and an appeal litigated before the Board.
	For service and non-construction State contracts, Maryland law does not impose any deadline upon a State procurement officer to render a decision. If the final decision of the State with regard to the Claim is unsatisfactory to the Company, the Company may file a Notice of Appeal with the Maryland State Board of Contact Appeals (the Board), which has exclusive initial jurisdiction of State contract claims concerning breach, performance, modification, or termination of contracts procured under Title II of Maryland's General Procurement Law.
	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.
