	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 six months ended October 3, 2014 and September 27, 2013, 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 28, 2014 (fiscal 2014). 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 April 3, 2015 (fiscal 2015).
	The Company reports its results based on a fiscal year convention that comprises four thirteen-week quarters. Every fifth year includes an additional week in the first quarter to prevent the fiscal year from moving from an approximate end of March date. As a result, the first quarter of fiscal 2015 was a fourteen week quarter.
	During the first quarter of fiscal 2015, the Company changed its accounting policy for the recognition of actuarial gains and losses for its defined benefit pension and other post-employment benefit plans (see Note 2). These changes have been reported through retrospective application of the new accounting methods to all periods presented. As a result, the unaudited Consolidated Condensed Statements of Operations, Comprehensive Income, Cash Flows, and Changes in Equity for the quarter ended September 27, 2013, the Consolidated Condensed Balance Sheet for the year ended March 28, 2014, and all related notes to such financial statements have been recast from those presented in the previously filed Form 10-Q and Form 10-K to reflect this change (see Note 2).
	Effective fiscal 2015, the Company changed its inter-company accounting policy. Previously, inter-company transactions between segments were generally reflected as inter-company revenue. Under the new policy, inter-company transactions are now generally treated as cost transfers. The new inter-company policy has been applied retrospectively, adjusting the segment results for all prior periods (see Note 15).
	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 six months ended October 3, 2014 and September 27, 2013:
		Quarter Ended						Six Months Ended
	(Amounts in millions, except per-share data)	October 3, 2014			September 27, 2013			October 3, 2014			September 27, 2013
	Gross favorable	$	43		$	58		$	72		$	75
	Gross unfavorable	(7		)	(17		)	(17		)	(26		)
	Total net adjustments, before taxes and non-controlling interest	$	36		$	41		$	55		$	49
	Impact on diluted EPS from continuing operations	$	0.15		$	0.18		$	0.21		$	0.2
	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 $55 million and $46 million as of October 3, 2014 and March 28, 2014, respectively.
	Depreciation expense was $155 million and $324 million for the quarter and six months ended October 3, 2014, respectively, and $165 million and $333 million for the quarter and six months ended September 27, 2013, respectively.

	Defined Benefit Pension Plan Accounting Policy Changes
	During the first quarter of fiscal 2015, the Company changed its accounting policy for the recognition of actuarial gains and losses for its defined benefit pension and other post-retirement benefit plans and the calculation of expected return on pension plan assets. Historically, the Company recognized actuarial gains and losses in excess of 10% of the greater of the market-related value of plan assets or the plans’ projected benefit obligations (the “corridor”) as a component of accumulated other comprehensive loss in its Consolidated Condensed Balance Sheets and, depending on the benefit plan, the Company amortized these gains and losses to earnings either over the remaining average service period for the active participants or over the average remaining life expectancy of the inactive participants. Additionally, for the Company’s U.S. plans and the Australian plan, the Company previously used a calculated value for the market-related valuation of pension plan assets, reflecting changes in the fair value of plan assets over a three-year and a one-year period, respectively. Under the Company’s new accounting policies, the Company recognizes changes in actuarial gains and losses and the changes in fair value of plan assets in earnings at the time of plan remeasurement, typically annually during the fourth quarter of each year as a component of net periodic benefit expense (and the Company no longer applies a corridor and, therefore, no longer defers any gains or losses). The new accounting policies result in the changes in actuarial gains and losses and the changes in fair value of plan assets being recognized in earnings in the year they occur, rather than amortized over time, and therefore recognized earlier than under the Company’s previous methods of accounting. The Company believes the new pension accounting policies are preferable as they recognize the effects of plan investment performance, interest rate changes, changes in actuarial assumptions as a component of earnings in the year in which they occur rather than amortized over time, and additionally, conform all plans to a consistent policy for determining market-related value of plan assets. These changes have been reported through retrospective application of the new accounting methods to all periods presented. The remaining components of pension/post-retirement expense, primarily current period service and interest costs and expected return on plan assets, will continue to be recorded on a quarterly basis. The cumulative effect of the retrospective application of new accounting policies was a decrease of $1.5 billion in retained earnings and a corresponding decrease in accumulated other comprehensive losses as of the beginning of fiscal 2014.
	In addition to the above mentioned accounting policy changes, the Company also changed the way in which it allocates the elements of net periodic pension (benefit) cost to its reportable segments to be aligned with changes in how the Company's chief operating decision maker evaluates segment performance. Historically, total net periodic pension (benefit) cost, including the amortization of deferred actuarial losses/(gains) and changes in fair value of plan assets, were reported within operating income, as defined by the Company, and fully allocated to reportable segments. Under the new allocation approach, the net actuarial gains and losses component of the net periodic pension (benefit) cost is excluded entirely from the Company’s definition of operating income and not allocated to the reportable segments. All of the other elements of net periodic pension (benefit) cost, excluding actuarial gains and losses, will continue to be included within operating income of the Company’s reportable segments. The Company has applied the change in the allocation approach retrospectively, adjusting segment reporting for all prior periods presented (see Note 15).
	The following tables present the effects of retrospectively applying the change in the pension accounting policies, on select line items of the accompanying unaudited Consolidated Condensed Financial Statements:

New Accounting Standards
During the first six months of fiscal 2015, the Company adopted the following Accounting Standard Update (ASU):
In February 2013, the Financial Accounting Standards Board (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” (“ASU 2013-04”). ASU 2013-04 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 ASU 2013-04 also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments in ASU 2013-04 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Effective March 29, 2014, CSC adopted the amendments in ASU 2013-04 and determined that the they did not have a material effect on CSC’s Consolidated Condensed Financial Statements.
Standards Issued But Not Yet Effective
The following ASUs were recently issued but have not yet been adopted by CSC:
In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”). ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. This ASU provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The amendments are effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early adoption is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. ASU 2014-15 will be effective for CSC for fiscal 2017. CSC is currently evaluating the impact that the adoption of ASU 2014-15 may have on CSC's Consolidated Condensed Financial Statements.
In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). ASU 2014-09 supersedes the revenue recognition requirements in ASC Topic 605, “Revenue Recognition” and some cost guidance included in ASC Subtopic 605-35, Revenue Recognition - Construction-Type and Production-Type Contracts”. The core principle of ASU 2014-09 is that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which CSC expects to be entitled in exchange for those goods or services. ASU 2014-09 requires the disclosure of sufficient information to enable users of CSC’s financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. CSC will also be required to disclose information regarding significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. Early adoption is not allowed. ASU 2014-09 provides two methods of retrospective application. The first method would require CSC to apply ASU 2014-09 to each prior reporting period presented. The second method would require CSC to retrospectively apply with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application. ASU 2014-09 will be effective for CSC beginning in fiscal 2018. CSC is currently evaluating the impact that the adoption of ASU 2014-09 may have on CSC’s Consolidated Condensed Financial Statements.
In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” (“ASU 2014-08”), which changes the requirements for reporting discontinued operations in Subtopic 205-20 “Presentation of Financial Statements - Discontinued Operations.” ASU 2014-08 changes the definition of discontinued operations by limiting discontinued operations reporting to disposals that represent strategic shifts that have (or will have) a major effect on an entity’s operations and financial results. Under current GAAP, many disposals, some of which may be routine in nature and not representative of a substantive change in an entity’s strategy, are reported in discontinued operations. ASU 2014-08 requires expanded disclosures for discontinued operations designed to provide users of financial statements with more information about the assets, liabilities, revenues, expenses and cash flows related to discontinued operations. ASU 2014-08 also requires an entity to disclose the pretax profit or loss of an individually significant component of an entity that does not qualify for discontinued operations reporting. The amendments in ASU 2014-08 are effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2014. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. ASU 2014-08 will be effective for CSC beginning in fiscal 2016. CSC is currently evaluating the impact that the adoption of ASU 2014-08 may have on CSC's Consolidated Condensed Financial Statements.
In January 2014, the FASB issued ASU No. 2014-05, "Service Concession Arrangements (Topic 853) (a consensus of the FASB Emerging Issues Task Force)” (“ASU 2014-05”). ASU 2014-05 provides guidance on the accounting for service concession arrangements, which are arrangements between a public-sector entity grantor and an operating entity under which the operating entity operates the grantor’s infrastructure (e.g. airports, roads, or bridges). The operating entity also may provide the construction, upgrading, or maintenance services of the grantor’s infrastructure. ASU 2014-05 specifies that an operating entity should not account for a service concession arrangement that is within the scope of this ASU as a lease in accordance with Topic 840, "Leases." ASU 2014-05 also specifies 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. ASU 2014-05 will be effective for CSC beginning in fiscal 2016. CSC believes that the adoption of ASU 2014-05 will not have a material effect on CSC's Consolidated Condensed Financial Statements.

	Defined Benefit Pension Plan Accounting Policy Changes
	During the first quarter of fiscal 2015, the Company changed its accounting policy for the recognition of actuarial gains and losses for its defined benefit pension and other post-retirement benefit plans and the calculation of expected return on pension plan assets. Historically, the Company recognized actuarial gains and losses in excess of 10% of the greater of the market-related value of plan assets or the plans’ projected benefit obligations (the “corridor”) as a component of accumulated other comprehensive loss in its Consolidated Condensed Balance Sheets and, depending on the benefit plan, the Company amortized these gains and losses to earnings either over the remaining average service period for the active participants or over the average remaining life expectancy of the inactive participants. Additionally, for the Company’s U.S. plans and the Australian plan, the Company previously used a calculated value for the market-related valuation of pension plan assets, reflecting changes in the fair value of plan assets over a three-year and a one-year period, respectively. Under the Company’s new accounting policies, the Company recognizes changes in actuarial gains and losses and the changes in fair value of plan assets in earnings at the time of plan remeasurement, typically annually during the fourth quarter of each year as a component of net periodic benefit expense (and the Company no longer applies a corridor and, therefore, no longer defers any gains or losses). The new accounting policies result in the changes in actuarial gains and losses and the changes in fair value of plan assets being recognized in earnings in the year they occur, rather than amortized over time, and therefore recognized earlier than under the Company’s previous methods of accounting. The Company believes the new pension accounting policies are preferable as they recognize the effects of plan investment performance, interest rate changes, changes in actuarial assumptions as a component of earnings in the year in which they occur rather than amortized over time, and additionally, conform all plans to a consistent policy for determining market-related value of plan assets. These changes have been reported through retrospective application of the new accounting methods to all periods presented. The remaining components of pension/post-retirement expense, primarily current period service and interest costs and expected return on plan assets, will continue to be recorded on a quarterly basis. The cumulative effect of the retrospective application of new accounting policies was a decrease of $1.5 billion in retained earnings and a corresponding decrease in accumulated other comprehensive losses as of the beginning of fiscal 2014.
	In addition to the above mentioned accounting policy changes, the Company also changed the way in which it allocates the elements of net periodic pension (benefit) cost to its reportable segments to be aligned with changes in how the Company's chief operating decision maker evaluates segment performance. Historically, total net periodic pension (benefit) cost, including the amortization of deferred actuarial losses/(gains) and changes in fair value of plan assets, were reported within operating income, as defined by the Company, and fully allocated to reportable segments. Under the new allocation approach, the net actuarial gains and losses component of the net periodic pension (benefit) cost is excluded entirely from the Company’s definition of operating income and not allocated to the reportable segments. All of the other elements of net periodic pension (benefit) cost, excluding actuarial gains and losses, will continue to be included within operating income of the Company’s reportable segments. The Company has applied the change in the allocation approach retrospectively, adjusting segment reporting for all prior periods presented (see Note 15).
	The following tables present the effects of retrospectively applying the change in the pension accounting policies, on select line items of the accompanying unaudited Consolidated Condensed Financial Statements:

New Accounting Standards
During the first six months of fiscal 2015, the Company adopted the following Accounting Standard Update (ASU):
In February 2013, the Financial Accounting Standards Board (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” (“ASU 2013-04”). ASU 2013-04 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 ASU 2013-04 also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments in ASU 2013-04 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Effective March 29, 2014, CSC adopted the amendments in ASU 2013-04 and determined that the they did not have a material effect on CSC’s Consolidated Condensed Financial Statements.
Standards Issued But Not Yet Effective
The following ASUs were recently issued but have not yet been adopted by CSC:
In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”). ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. This ASU provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The amendments are effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early adoption is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. ASU 2014-15 will be effective for CSC for fiscal 2017. CSC is currently evaluating the impact that the adoption of ASU 2014-15 may have on CSC's Consolidated Condensed Financial Statements.
In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). ASU 2014-09 supersedes the revenue recognition requirements in ASC Topic 605, “Revenue Recognition” and some cost guidance included in ASC Subtopic 605-35, Revenue Recognition - Construction-Type and Production-Type Contracts”. The core principle of ASU 2014-09 is that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which CSC expects to be entitled in exchange for those goods or services. ASU 2014-09 requires the disclosure of sufficient information to enable users of CSC’s financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. CSC will also be required to disclose information regarding significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. Early adoption is not allowed. ASU 2014-09 provides two methods of retrospective application. The first method would require CSC to apply ASU 2014-09 to each prior reporting period presented. The second method would require CSC to retrospectively apply with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application. ASU 2014-09 will be effective for CSC beginning in fiscal 2018. CSC is currently evaluating the impact that the adoption of ASU 2014-09 may have on CSC’s Consolidated Condensed Financial Statements.
In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” (“ASU 2014-08”), which changes the requirements for reporting discontinued operations in Subtopic 205-20 “Presentation of Financial Statements - Discontinued Operations.” ASU 2014-08 changes the definition of discontinued operations by limiting discontinued operations reporting to disposals that represent strategic shifts that have (or will have) a major effect on an entity’s operations and financial results. Under current GAAP, many disposals, some of which may be routine in nature and not representative of a substantive change in an entity’s strategy, are reported in discontinued operations. ASU 2014-08 requires expanded disclosures for discontinued operations designed to provide users of financial statements with more information about the assets, liabilities, revenues, expenses and cash flows related to discontinued operations. ASU 2014-08 also requires an entity to disclose the pretax profit or loss of an individually significant component of an entity that does not qualify for discontinued operations reporting. The amendments in ASU 2014-08 are effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2014. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. ASU 2014-08 will be effective for CSC beginning in fiscal 2016. CSC is currently evaluating the impact that the adoption of ASU 2014-08 may have on CSC's Consolidated Condensed Financial Statements.
In January 2014, the FASB issued ASU No. 2014-05, "Service Concession Arrangements (Topic 853) (a consensus of the FASB Emerging Issues Task Force)” (“ASU 2014-05”). ASU 2014-05 provides guidance on the accounting for service concession arrangements, which are arrangements between a public-sector entity grantor and an operating entity under which the operating entity operates the grantor’s infrastructure (e.g. airports, roads, or bridges). The operating entity also may provide the construction, upgrading, or maintenance services of the grantor’s infrastructure. ASU 2014-05 specifies that an operating entity should not account for a service concession arrangement that is within the scope of this ASU as a lease in accordance with Topic 840, "Leases." ASU 2014-05 also specifies 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. ASU 2014-05 will be effective for CSC beginning in fiscal 2016. CSC believes that the adoption of ASU 2014-05 will not have a material effect on CSC's Consolidated Condensed Financial Statements.

	Fiscal 2015 Acquisition
	On July 31, 2014, CSC acquired a privately held entity for $35 million in an all cash transaction. CSC acquired this entity primarily to enhance its cyber security, systems engineering, and software development service offerings in the federal intelligence sector. The purchase price was allocated to assets acquired and liabilities assumed based on preliminary estimates of fair value at the date of acquisition, as follows: $4 million to current assets, $9 million to an intangible asset other than goodwill, $9 million to current liabilities, and $31 million to goodwill. The intangible asset, which is associated with the Company's customer relationships and government programs, will be amortized over 15 years. The goodwill is associated with the Company's North American Public Sector (NPS) segment and is expected to be tax deductible. Pro forma financial information for this acquisition is not presented as the effects of the acquisition are not material to CSC's consolidated results. The allocation of purchase price is preliminary and is subject to additional information related to the liabilities that existed as of the acquisition date.
	Fiscal 2014 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 to assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition: $2 million to current and other long-term assets, $2 million to current and long-term liabilities, and $27 million to goodwill. As of the acquisition date, the fair value of trade receivables approximated book value and was considered fully recoverable. The goodwill is associated with the Company's GBS segment and is not tax-deductible. Pro forma financial information for this acquisition was not presented as the effects of the acquisition were not material to CSC's consolidated results.
	Fiscal 2015 Divestiture
	On July 31, 2014, CSC completed the sale of a German software business to a strategic investor for cash consideration of $3 million. This divestiture, which was a part of the GBS segment's healthcare group, resulted in a pre-tax loss of $22 million, representing the excess of the carrying value of the net assets of the business and transaction costs over the net proceeds. The divested assets and liabilities included: current assets of $54 million (including $21 million of cash); goodwill of $0; other noncurrent assets of $25 million; current liabilities of $33 million; and noncurrent liabilities of $23 million. The historical results of this business have been presented as discontinued operations in the Company's unaudited Consolidated Condensed Statement of Operations.
	Fiscal 2014 Divestitures
	On July 19, 2013, CSC's NPS segment completed the sale of its base operations, aviation and range services business unit, Applied Technology Division (ATD), to a strategic investor for cash consideration of approximately $178 million, plus a net working capital adjustment receivable of $6 million, for a pre-tax gain on disposal of $77 million. During the first quarter of fiscal 2015, NPS recorded a $1 million final net working capital adjustment, which reduced the total gain on sale of ATD.
	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. During the fourth quarter of fiscal 2014, the Company received cash of $3 million, representing the final net working capital adjustment, and reduced the gain on disposal by $1 million. During the first quarter of fiscal 2015, CSC received an additional $2 million as a purchase price adjustment related to this divestiture, which was recorded as additional gain on sale on disposition.
	Pursuant to the pension accounting policy change (see Note 2), the income from discontinued operations, net of taxes, for the second quarter and first six months of fiscal 2014 increased $17 million and $19 million, respectively due to the reduced pension expense.
	A summary of the results of the discontinued operations is presented below:

	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 disclosures 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 and accounting determinations with respect to 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 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 has been availing itself of the Wells process by making a Wells submission to explain its views concerning such matters, which are aided by the Audit Committee's independent investigation and certain expert opinions of outside professionals. The Company made such a submission on January 14, 2014 and a supplemental submission on April 9, 2014. The Company, through outside counsel, has been in continuing discussions with the SEC Enforcement staff concerning a potential resolution of the staff’s investigation involving the Company, as previously disclosed. The SEC's staff is of the view that losses associated with the NHS contract should have been recognized prior to fiscal 2012 and continues to disagree with the Company's historical accounting and disclosures with respect to the NHS contract. Discussions are still ongoing but to date, those discussions have not resulted in a resolution. 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 SEC enforcement action or settlement 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 the pre-tax income (loss) from continuing operations of the recorded out of period adjustments in the first quarter of fiscal 2015, fiscal 2014 and fiscal 2013 is attributable to the following prior fiscal years:
		Increase/(Decrease)
	(Amounts in millions)	Fiscal 2013 Adjustments				Fiscal 2014 Adjustments			First Six Months Fiscal 2015 Adjustments			Total Adjustments
	Fiscal 2015	$	—			$	—		$	(12	)	$	(12	)
	Fiscal 2014	—				(2		)	13			11
	Fiscal 2013	6				4			(1		)	9
	Prior fiscal years (unaudited)	(6		)		(2		)	—			(8		)
	See Note 15 for a summary of the effect of the pre-tax out of period adjustments on the Company's segment results for the quarters ended October 3, 2014 and September 27, 2013, respectively.
	Fiscal 2015 Adjustments
	During the quarter and six months ended October 3, 2014, the Company identified and recorded net adjustments decreasing pre-tax income from continuing operations by $4 million and increasing pre-tax income from continuing operations $12 million, respectively, that should have been recorded in prior periods.
	The $4 million decrease in pre-tax income from continuing operations recorded during the second quarter of fiscal 2015 was primarily attributable to adjustments increasing cost of services partially offset by adjustments increasing revenue that should have been recorded in the first quarter of fiscal 2015. Out of period adjustments identified during the second quarter of fiscal 2015 that should have been recorded in prior fiscal years were not material.
	Adjustments recorded during the quarter ended October 3, 2014 increased net income attributable to CSC common shareholders by $2 million.
	The $12 million increase in pre-tax income from continuing operations recorded during the first six months of fiscal 2015 primarily included lower fiscal 2014 variable compensation partially offset by certain adjustments related to cost of services that were identified late in the 2014 close process and, therefore, were not included in the Company's fiscal 2014 Consolidated Financial Statements.Adjustments recorded during the six months ended October 3, 2014, that should have been recorded in prior fiscal years, increased net income attributable to CSC common shareholders by $7 million.
	The impact of out of period adjustments recorded during fiscal 2015 on select line items of the unaudited Consolidated Condensed Statements of Operations for the quarter and six months ended October 3, 2014, using the rollover method, is shown below:

For the six months ended October 3, 2014, the out of period impact on the unaudited Consolidated Condensed Balance Sheet of the adjustments included in income from continuing operations before taxes under the roll over method is shown below:
(Amounts in million)	Increase/(Decrease)		3-Oct-14
Receivable, net of allowance for doubtful accounts	Increase		$	5
Property and Equipment	Decrease		1
Software, net of accumulated amortization	Decrease		1
Outsourcing contract costs, net of accumulated amortization	Increase		2
Other assets	Decrease		3
Accrued expenses and other current liabilities	Decrease		14

The Company has determined that the impact of the consolidated out of period adjustments recorded in the six months ended October 3, 2014 is immaterial to the consolidated results, financial position and cash flows for the second quarter and first six months of fiscal 2015 and prior periods. Consequently, the cumulative effect of these adjustments was recorded during fiscal 2015.
Fiscal 2014 Adjustments
During the second quarter and through the first six months of fiscal 2014, the Company recorded net pre-tax adjustments decreasing income from continuing operations, before taxes by $11 million and $2 million, respectively, 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 selling, general and administrative (SG&A) expense reversing excess capitalization associated with internal systems development. Adjustments, net of tax, during the second quarter and through the first six months of fiscal 2014 that should have been recorded in prior fiscal years decreased income from continuing operations by $20 million and $22 million, respectively. The differences are 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 was negligible and for the first six months of fiscal 2014 was an $8 million increase in tax expense. The tax effect on the pre-tax adjustments for the first six months of fiscal 2014 resulted in an increase in tax expense despite the net reduction in income from continuing operations before taxes 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 second quarter and through the first six months of fiscal 2014 resulted in an increase to income tax expense of $9 million and $11 million, respectively. 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. The difference is attributable to the tax effect of the net pre-tax adjustments.
During periods subsequent to September 27, 2013, the Company recorded out of period adjustments with a net pre-tax impact to income from continuing operations of $3 million, primarily in the GIS segment, and $11 million, primarily in the GBS segment, that should have been recorded in the second quarter and first six months of fiscal 2014, respectively. Had such adjustments been recorded in the appropriate period, income from continuing operations before taxes for the second quarter and for the first six months of fiscal 2014 would have been higher by $3 million and $11 million, respectively.
The impact of out of period adjustments recorded during fiscal 2014, and the first six months of fiscal 2015, on select line items of the unaudited Consolidated Condensed Statements of Operations for the quarter and first six months ended September 27, 2013, using the rollover method, is shown below:

The Company determined that the impact of the consolidated out of period adjustments recorded in the second quarter of fiscal 2014 was immaterial to the consolidated results, financial position and cash flows for the second quarter of fiscal 2014 and prior periods. Consequently, the cumulative effect of these adjustments was recorded during fiscal 2014.

	The Company's money market funds, money market deposit accounts and time deposits are reported in cash and cash equivalents and short-term investments are included in prepaid expenses and other current assets. The balance sheet classifications of the Company's derivative instruments are presented in Note 8. 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, interest rate swap contracts and total return swaps (see Note 8). 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. Total return swaps are settled on the last day of every fiscal month. 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 quarters and six months ended October 3, 2014 and September 27, 2013.
	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 $1,954 million and $1,874 million, and the estimated fair value was $2,059 million and $2,057 million, as of October 3, 2014 and March 28, 2014, 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 Company is subject to counterparty risk in connection with its derivative instruments (see Note 8). With respect to its foreign currency derivatives, as of October 3, 2014 there were two counterparties with concentration of credit risk. Based on gross fair value of these foreign currency derivative instruments, the maximum amount of loss that the Company could incur is less than $1 million. With respect to its interest rate swaps, there were three counterparties with concentration of risk and the maximum amount of loss that the Company could incur was $7 million as of October 3, 2014.
	The primary financial instruments other than derivatives (see Note 8) 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 October 3, 2014, the Company had $16 million of accounts receivable, $11 million of related allowance for doubtful accounts, $1 million of other assets, and $4 million of accounts payable with customers involved in bankruptcy proceedings.

Derivative Instruments	'
	Derivative Instruments
	The Company is exposed to certain market risks including the effect of changes in interest rates and foreign currency exchange rates, and the value of notional investments underlying the Company's non-qualified deferred compensation plan. Changes in benchmark interest rates can impact the fair value of the Company's term notes, whereas changes in foreign currency exchange rates can impact the Company's foreign currency denominated monetary assets and liabilities and forecasted transactions in foreign currency. Market volatility of the notional investments underlying the Company's non-qualified deferred compensation plan can impact the Company's obligations under the plan. The Company uses derivative instruments to mitigate the impact of these market risks and not for trading or any speculative purpose.
	The Company designates certain derivative instruments as hedges, for purposes of hedge accounting. For such derivative instruments, the Company documents its risk management objectives and strategy for undertaking hedging transactions, as well as all relationships between hedging and hedged risks. The derivative instruments designated for hedge accounting consist mainly of interest rate swaps, and foreign currency forward contracts. Changes in the fair value measurements of the cash flow hedge derivative instruments are reflected as adjustments to other comprehensive income (OCI), while changes in fair value measurements of interest rate swaps are recorded in current period earnings.
	The derivative instruments not designated as hedges for purposes of hedge accounting include total return swaps and certain short-term foreign currency forward and option contracts. These instruments are recorded at their respective fair values and the change in their value is reported in current period earnings.
	All cash flows associated with the Company's derivative instruments are classified as operating activities in the Consolidated Condensed Statement of Cash Flows.
	The following table presents the fair values of derivative instruments included on the Consolidated Condensed Balance Sheets as of October 3, 2014 and March 28, 2014:

	Fair value hedges
	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 the short-cut method of hedge accounting, as defined under ASC Topic 815, “Derivatives and Hedging.” Accordingly, changes in the fair values of the interest rate swaps are reported in earnings and fully offset changes in the fair value of the underlying debt (see Note 9); therefore, no net gain or loss is recognized in the unaudited Consolidated Condensed Statement of Operations.
	The following table presents the pre-tax gains (losses) related to the fair value hedges and the related hedged items, for the quarters ended October 3, 2014 and September 27, 2013, respectively:

	Cash flow hedges
	During the first quarter of fiscal 2015, the Company designated certain foreign currency forward contracts as cash flow hedges, to reduce risks related to certain Indian Rupee denominated intercompany obligations and forecasted transactions for a nine-month period through March 2015. As of October 3, 2014, the notional amount of foreign currency forward contracts designated as cash flow hedges was $285 million.
	For the quarter ended October 3, 2014, the Company performed an assessment at the inception of the cash flow hedge transactions that determined all critical terms of the hedging instruments and hedged items match; therefore there is no ineffectiveness to be recorded and all changes in the hedging instruments’ fair value are recorded in accumulated Other Comprehensive Income (OCI) and subsequently reclassified into earnings in the period during which the hedged transactions are recognized in earnings. The Company performs an assessment of critical terms on an on-going basis throughout the hedging period. During the quarter ended October 3, 2014, the Company did not discontinue any cash flow hedge for which it was probable that the hedged transaction would not occur. As of October 3, 2014, $6 million of the existing amount of losses related to the cash flow hedge reported in accumulated OCI are expected to be reclassified into earnings within the next twelve months.
	The following table presents the pre-tax gains (losses) associated with the cash flow hedges, recognized in accumulated OCI, for the quarters ended October 3, 2014 and September 27, 2013, respectively:

	Total return swaps
	Beginning in the first quarter of fiscal 2015, the Company entered into total return swaps (TRS) derivative contracts to hedge market volatility of the notional investments underlying the Company's deferred compensation obligations. Changes in the fair value of these derivatives and changes in the associated hedged liabilities are recorded in cost of services and selling, general and administrative expenses. The TRS are entered into monthly and are settled on the last day of every fiscal month.
	Foreign currency derivatives
	The Company manages exposure to fluctuations in foreign currencies by using short-term foreign currency forward and option contracts to economically hedge certain foreign currency denominated assets and liabilities, including intercompany accounts and loans. For accounting purposes, these foreign currency option and forward contracts are not designated as hedges, as defined under ASC 815, “Derivatives and Hedging,” and all changes in their fair value are reported in current period earnings within the other income (expense) line of the unaudited Consolidated Statement of Operations. The notional amount of the foreign currency forward contracts outstanding as of October 3, 2014 and March 28, 2014 was $542 million and $816 million, respectively. The notional amount of option contracts outstanding as of October 3, 2014 and March 28, 2014 was $0 and $81 million, respectively.
	The following table presents the pretax amounts affecting income related to derivatives not designated for hedge accounting for the quarters ended October 3, 2014 and September 27, 2013, respectively:

	Other risks
	As discussed further in Note 7, the Company is exposed to the risk of losses in the event of non-performance by the counterparties to its derivative contracts. To mitigate counterparty credit risk, the Company regularly reviews its credit exposure and the creditworthiness of the counterparties. The Company also enters into enforceable master netting arrangements with some of its counterparties. However for financial reporting purposes it is the Company’s policy to not offset derivative assets and liabilities despite the existence of enforceable master netting arrangements with some of its counterparties.
	The following table provides information about the potential effect of such netting arrangements on the Company’s derivative instruments:
		Fair Value as of
		October 3, 2014								March 28, 2014
	(Amounts in millions)	Assets				Liabilities				Assets				Liabilities
	Gross amount of derivative instruments recognized in Consolidated Condensed Balance Sheets	$	7			$	11			$	5			$	4
	Gross amounts not offset in the Consolidated Condensed Balance Sheets (1)	—				—				—				—
	Net amount	$	7			$	11			$	5			$	4
	(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.

	Pension and Other Post-Retirement Benefit Plans
	The Company and its subsidiaries sponsor a number of pension and other post-retirement benefit plans. During the first quarter of fiscal 2015, the Company changed its accounting policies related to its defined benefit pension and other post-retirement benefit plans (see Note 2).
	The net periodic pension benefit for U.S. and non-U.S. pension plans included the following components:
		Quarter Ended

	Settlement loss (income)	2			(28		)	—			—
	Net periodic pension benefit	$	(40	)	$	(58	)	$	(33	)	$	(3	)
	The year-over-year decrease in net periodic pension benefit, both for the second quarter and the first six months of fiscal 2015, was primarily due to the fiscal 2014 settlement gain associated with the ATD sale (see Note 4) that did not recur in fiscal 2015, greater return on pension assets of the U.S. and U.K. plans, due to a higher amount of pension assets at the beginning of fiscal 2015 as compared to fiscal 2014 as well as higher than expected returns on the pension assets and a reduction in the accrual for contractual termination pension benefits.
	During the first quarter of fiscal 2015, a curtailment loss of $2 million was recorded. This curtailment charge was associated with one of the U.S. pension plans and resulted from amortization of the prior service cost. The plan was remeasured on April 30, 2014 using a discount rate of 4.14%, a decrease from 4.23% at the prior fiscal year end, which resulted in an increase to the fair value of actuarial pension benefit obligation of $1 million, increasing the plan’s unfunded obligations.
	On July 31, 2014, CSC completed the sale of a German software business, which had a pension plan (see Note 4). The plan was remeasured as of the date of the sale, resulting in settlement costs totaling $3 million, which has been reported within discontinued operations.
	On July 19, 2013, CSC completed the sale of ATD (See Note 4), which had a pension and a retiree medical plan. The plans were remeasured as of the date of the sale, resulting a in settlement benefit of $28 million associated with the pension plan and $8 million associated with the retiree medical plan, and a reduction to long-term liabilities of $28 million.
	The Company contributed $10 million and $46 million to the defined benefit pension plans during the second quarter and six months ended October 3, 2014, respectively. The Company expects to contribute $18 million during the remainder of fiscal 2015. 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 2015.
	The components of net periodic benefit cost for other post-retirement benefit plans, reported on a global basis, included the following:
		Quarter Ended
	(Amounts in millions)	October 3, 2014			September 27, 2013
	Service cost	$	1		$	1
	Interest cost	2			2
	Expected return on assets	(2		)	(1		)

	Amortization of prior service cost	(1		)	(2		)
	Settlement (gain)	—			(8		)
	Net provision for post-retirement benefits	$	2		$	(5	)
	The Company contributed $2 million and $4 million to the other post-retirement benefit plans during the quarter and six months ended October 3, 2014. The Company expects to contribute $4 million during the remainder of fiscal 2015.
	In September 2014, CSC initiated a pension lump sum or annuity distribution offer to U.S. terminated vested participants who earned benefits in a CSC sponsored pension plan. Eligible participants have the option to choose a distribution from the pension plan in the form of a single lump sum payment or annuity plan. Distributions to participants, who accept the offer, are expected during December 2014 (see Note 20).
	During the third quarter of fiscal 2015, the Company amended its retiree medical health plans to provide coverage to eligible Medicare retirees through a private insurance marketplace. The insurance marketplace will allow retirees to choose the health insurance terms, cost and coverage that best fit their needs. CSC will continue to provide financial support to the Medicare eligible participants in the form of a tax free contribution to a health reimbursement account (see Note 20).

	Income Taxes
	The Company's effective tax rate from continuing operations (ETR) was 27.8% and 26.8% for the quarter and six months ended October 3, 2014, respectively, and 32.2% and 31.7% for the quarter and six months ended September 27, 2013, respectively. The following are the primary drivers of the ETR for the six months ended October 3, 2014 and September 27, 2013, respectively. For the tax impact of discontinued operations, see Note 4.
	•	During the second quarter and six months ended October 3, 2014 and September 27, 2013, the ETR decreased due to the global mix of income and changes in valuation allowances in certain non-U.S. jurisdictions.
	•	During the second quarter and six months ended September 27, 2013, 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 second quarter and six months ended September 27, 2013 by 4.2% and 2.1%, respectively.
	There were no material changes to uncertain tax positions as of the second quarter of fiscal 2015 compared to the fiscal 2014 year-end.
	The Internal Revenue Service (IRS) examined several issues for the fiscal years 2008 through 2010 that resulted in audit adjustments to the Company's federal income tax returns. The Company does not agree with many of the proposed adjustments and has filed an Appeals brief. As a result, the Company expects to reach a resolution no earlier than fiscal year 2016. The significant items subject to appeal primarily relate to foreign exchange losses and other U.S. international tax issues. 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 $28 million, excluding interest, penalties, and tax carryforwards.
	Significant management judgment is required in determining the Company's provision for income taxes, deferred tax assets and liabilities, and any valuation allowance recorded against deferred tax assets. A valuation allowance has been recorded against certain deferred tax assets due to uncertainties related to the ability to utilize these assets. The valuation allowance is based on historical earnings, estimates of taxable income by jurisdiction and the period over which the deferred tax assets will be recoverable. Valuation allowances are evaluated periodically and will be subject to change in each future reporting period as a result of changes in various factors. Based on recent earnings in certain jurisdictions there is a reasonable possibility that, within fiscal 2015, sufficient positive evidence may become available to reach a conclusion that a portion of the valuation allowance will no longer be needed. As such, the Company may release a portion of its valuation allowance against its deferred taxes, which would result in the recognition of certain deferred tax assets and an income tax benefit for the period in which such release is recorded. Any such adjustment could result in a favorable impact that could be material to the Company's financial position and results of operations.

	For the quarters ended October 3, 2014 and September 27, 2013, the Company recognized stock-based compensation expense as follows:
			Quarter Ended							Six Months Ended
	(Amounts in millions)		October 3, 2014				September 27, 2013			October 3, 2014		September 27, 2013

	Total		$	16			$	16		$	35	$	33
	Total, net of tax		$	10			$	10		$	23	$	21
	Stock-based compensation for the first six months of fiscal 2015 increased $2 million when compared to the same period of the prior year. The increases included $8 million due to higher expense associated with the restricted stock units (RSUs) granted to the employees of ServiceMesh, which was acquired in the third quarter of fiscal 2014, and $7 million due to the fiscal 2015 option and RSU grants, impacted by the Company's higher stock price. These increases in expense were offset by $13 million of lower expense due to adjustments for forfeitures for terminating employees.
	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 six months ended October 3, 2014 and September 27, 2013 were $18.34 and $16.35 per share, respectively. In calculating the compensation expense for its stock incentive plans, the Company used the following weighted-average assumptions:
		Six Months Ended
		October 3, 2014			September 27, 2013
	Risk-free interest rate	2.07	%		2.08	%
	Expected volatility	33	%		35	%
	Expected term (in years)	6.21			6.7
	Dividend yield	1.5	%		1.67	%
	For the six months ended October 3, 2014 and September 27, 2013, the tax benefit realized from stock option exercises and RSU settlements was $30 million and $13 million, respectively, and the excess tax benefit was $12 million and $5 million, respectively.
	Employee Incentives
	The Company currently has two active stock incentive plans that authorize the issuance of stock options, restricted stock and other stock-based incentives to employees upon terms approved by the Compensation Committee of the Board of Directors. The Company issues authorized but previously unissued shares upon the exercise of stock options, the granting of restricted stock and the settlement of RSUs. As of October 3, 2014, 15,593,681 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:

	The total intrinsic value of options exercised during the six months ended October 3, 2014 and September 27, 2013 was $53 million and $19 million, respectively. The cash received from stock options exercised during the six months ended October 3, 2014 and September 27, 2013 was $125 million and $85 million, respectively.
	As of October 3, 2014, there was $39 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 2.02 years.
	Restricted Stock Units
	Information concerning RSUs granted under stock incentive plans is as follows:
		As of October 3, 2014

	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. During the first quarter of fiscal 2015, CSC completed this program and the Company's Board of Directors approved a new share repurchase program authorizing up to an additional $1.5 billion in share repurchases of the Company's outstanding common stock. CSC has been implementing these programs through purchases in compliance with SEC 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 current repurchase program.
	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.
	During the second quarter and first six months of fiscal 2015, 4,646,630 and 7,055,050 shares were purchased, respectively, through open market purchases for an aggregate consideration of $278 million and $428 million, respectively, at a weighted average price of $59.77 and $60.63 per share, respectively. The Company also paid $6 million during the first quarter of fiscal 2015 for shares purchased during the fourth quarter of fiscal 2014 that had not yet settled in cash by March 28, 2014. The approximate amount for which shares may yet be purchased under the share repurchase program at October 3, 2014 is $1.1 billion.
	During the second quarter of fiscal 2015, the Company entered into an accelerated share repurchase (ASR) agreement with a financial institution by advancing cash proceeds of $125 million. At inception, the ASR was initially settled by delivery of 1,258,651 shares to the Company, all of which were immediately retired. The actual number of shares required to be delivered to the Company was based on the trading prices of the Company's stock over a defined trading execution period under the agreement. Under certain circumstances, portions of the original amounts advanced to the financial counterparty could be returned to the Company.
	Subsequent to the end of the second quarter, after completion of the pricing period, the financial institution will return $50 million to the Company and deliver 31,830 additional shares. As a result, the Company will have repurchased under the ASR, 1,290,481 shares for a net consideration of $75 million, at an average price of $58.12 per share.
	During the second quarter and first six months ending September 27, 2013, the Company repurchased 2,044,109 and 4,873,222 shares through open market purchases for an aggregate consideration of $102 million and $229 million, respectively, at a weighted average price of $49.85 and $46.91 per share, respectively.

	Effective fiscal 2015, the Company changed its inter-company accounting policy. Previously, inter-company transactions were generally reflected as inter-company revenue. Under the new policy, inter-company transactions are now generally treated as cost transfers. The new inter-company policy has been applied retrospectively, adjusting the segment results for all prior periods presented (see Note 1). In addition, segment results for all prior periods presented have been recast to reflect the change in the Company's pension accounting policies (see Note 2).
	The following table summarizes operating results by reportable segment:
	(Amounts in millions)		GBS			GIS			NPS			Corporate			Eliminations		Total

	Operating income (loss) provides useful information to the Company’s management for assessment of the Company’s performance and results of operations, and is one of the financial measures utilized to determine executive compensation. As mentioned in Note 2, in conjunction with the change in its pension accounting policies, the net actuarial gains and losses component of the net periodic pension benefit/cost are excluded from the Company’s definition of operating income and not allocated to the reportable segments; but instead recorded at the corporate level. All of the other elements of net periodic pension benefit/cost continue to be included within operating income of the Company’s reportable segments. The Company has applied the change in the allocation approach retrospectively, adjusting all prior periods.
	A reconciliation of consolidated operating income to income from continuing operations before taxes is as follows:
			Quarter Ended						Six Months Ended
	(Amounts in millions)		October 3, 2014			September 27, 2013			October 3, 2014			September 27, 2013

	Income from continuing operations before taxes		$	245		$	239		$	459		$	473
	(1) The impact of the change in pension accounting policy was an increase in operating income of $21 million and $43 million for the second quarter and first six months ended of fiscal 2015, respectively, and an increase in operating income of $23 million and $46 million for the second quarter and first six months of fiscal 2014, respectively.
	During the second quarter and the first six months of fiscal 2015 and fiscal 2014, the Company recorded certain pre-tax out of period adjustments which should have been recorded in prior fiscal periods (see Note 5). The following tables summarize the effect of the pre-tax out of period adjustments on the GBS, GIS, and NPS segment results for the quarters and six months ended October 3, 2014 and September 27, 2013, as if the adjustments had been recorded in the appropriate period:

	Balance as of October 3, 2014, net	$	667		$	198		$	819	$	1,684
	The fiscal 2015 addition to goodwill is due to the second quarter NPS acquisition described in Note 4. The foreign currency translation amount reflects the impact of currency movements on non-U.S. dollar-denominated goodwill balances.
	As of the beginning of fiscal 2015, a reassignment of goodwill occurred because of changes to the way in which GBS segment leadership began to regularly review the operating results within the GBS segment and because of the availability of discrete financial information. Goodwill was reassigned using a relative fair value allocation approach. CSC performed a quantitative and qualitative goodwill impairment assessment for the changed reporting units and determined that there was no indication that goodwill was impaired for those reporting units as of the end of the first quarter of fiscal 2015.
	The Company tests goodwill for impairment on an annual basis, as of the first day of the second fiscal quarter, and between annual tests if an event occurs, or circumstances change, that would more likely than not reduce the fair value of a reporting unit below its carrying amount. For the Company’s annual goodwill impairment assessment as of July 5, 2014, the Company first assesses qualitative factors to determine whether events or circumstances existed that would lead the Company to conclude that it is more likely than not that the fair value of any of its reporting units was below their carrying amounts. If the Company determines that it is not more likely than not, then proceeding to step one of the two-step goodwill impairment test is not necessary. The Company determined that, based on its qualitative assessment of such factors for all reporting units, no reporting units met the more-likely-than-not threshold; accordingly, the Company did not perform further analysis.
	At the end of the second quarter of fiscal 2015, 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 and require an interim goodwill impairment test. The Company determined that there were no such indicators and, as a result, it was unnecessary to perform an interim impairment test as of October 3, 2014.
	Other Intangible Assets
	A summary of amortizable intangible assets is as follows:

Amortization expense related to capitalized software was $56 million and $45 million for the quarters ended October 3, 2014, and September 27, 2013, respectively.
	Amortization related to intangible assets was $222 million and $192 million for the six months ended October 3, 2014, and September 27, 2013, respectively, including reductions of revenue for amortization of outsourcing contract cost premiums of $17 million and $17 million and for amortization of contract related intangible assets of $5 million and $6 million, respectively. Amortization expense related to capitalized software was $110 million and $89 million for the six months ended October 3, 2014, and September 27, 2013, respectively.
	Estimated amortization expense related to intangible assets as of October 3, 2014, for the remainder of fiscal 2015 is $198 million, and for each of the fiscal years 2016, 2017, 2018 and 2019, is as follows: $325 million, $249 million, $200 million and $179 million, respectively.
	During the second quarter and first six months of fiscal 2015, CSC sold certain intangible assets to a third party for total consideration of $19 million and $43 million of which cash consideration was received of $10 million and $14 million, respectively. As a result, CSC recorded a gain on sale of $19 million and $43 million, respectively, as a reduction of cost of sales in its GIS segment. As of October 3, 2014, CSC had $29 million of outstanding receivables related to these sales, which will be paid in quarterly installments.

	Restructuring Costs
	The Company recorded $(7) million and $15 million of restructuring costs for the quarters ended October 3, 2014 and September 27, 2013, respectively. For the six months ended October 3, 2014 and September 27, 2013, the Company recorded $3 million and $22 million, respectively. The costs recorded during the quarter and six months ended October 3, 2014 were in connection with actions under the Fiscal 2015 Plan, Fiscal 2013 Plan and Fiscal 2012 Plan, as described below. The costs recorded during the quarter and six months ended September 27, 2013 were in connection with actions under both the Fiscal 2013 and Fiscal 2012 plans, as described below.
	Fiscal 2015 Plan
	In June 2014, the Company initiated restructuring actions (the Fiscal 2015 Plan) across its business segments. The objectives of the Fiscal 2015 Plan are to further reduce headcount in order to align resources to support business needs. Management expects that further actions will be taken during fiscal 2015, which could result in additional charges.
	The composition of the restructuring liability for the Fiscal 2015 Plan as of October 3, 2014 is as follows:
	(Amounts in millions)		Restructuring liability as of March 28, 2014			Costs expensed in fiscal 2015			Less: costs not affecting restructuring liability (1)			Cash paid			Other			Restructuring liability as of October 3, 2014
	Workforce reductions		$	—		$	15		$	—		$	(3	)	$	(1	)	$	11
	(1)	Charges primarily consist of pension benefit augmentations and are recorded as a pension liability.
	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 were 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 utilization of facilities. Actions under the Fiscal 2013 Plan commenced in September 2012 and continued through the end of fiscal 2014. The expense reduction in the first six months of fiscal 2015 was due to cancellation of a portion of a restructuring plan in a region, as well as revisions on plans that were executed at lower than expected costs.
	The composition of the restructuring liability for the Fiscal 2013 Plan as of October 3, 2014 is as follows:

	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 carried out in fiscal 2013 and fiscal 2014. There were no restructuring costs for the Fiscal 2012 Plan accrued during the first six months of fiscal 2015.
	The composition of the restructuring liability for the Fiscal 2012 Plan as of October 3, 2014 is as follows:
	(Amounts in millions)		Restructuring liability as of March 28, 2014			Costs expensed in fiscal 2015			Cash paid			Other(1)			Restructuring liability as of October 3, 2014

	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 the 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 CSC 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 and the overall availability of such funding. 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, but has no obligation to, 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 as 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 October 3, 2014, the amount of deferred costs and deferred revenues was $17 million and $188 million, respectively.

	Commitments and Contingencies
	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 October 3, 2014, the Company had $27 million of outstanding surety bonds and $80 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 effect on its consolidated results of operations or financial position.
	The Company also uses stand-by letters of credit, in lieu of cash, to support various risk management insurance policies. These letters of credit represent a contingent liability and the Company would only be liable if it defaults on its payment obligations towards these policies. As of October 3, 2014, the Company had $66 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 October 3, 2014:
	(Amounts in millions)	Fiscal 2015		Fiscal 2016		Fiscal 2017 and thereafter		Total
	Surety bonds	$	9	$	18	$	—	$	27

	Stand-by letters of credit	31		22		13		66

	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 18 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 disclosures 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 and accounting determinations with respect to 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's periodic filings 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 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 SEC 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 SEC that such an action should not be brought. The Company has been availing itself of the Wells process by making a Wells submission to explain its views concerning such matters, which are aided by the Audit Committee's independent investigation and certain expert opinions of outside professionals. The Company made such a submission on January 14, 2014 and a supplemental submission on April 9, 2014. The Company, through outside counsel, has been in continuing discussions with the SEC Enforcement staff concerning a potential resolution of the staff’s investigation involving the Company, as previously disclosed. The SEC's staff is of the view that losses associated with the NHS contract should have been recognized prior to fiscal 2012 and continues to disagree with the Company's historical accounting and disclosures with respect to the NHS contract. Discussions are still ongoing but to date, those discussions have not resulted in a resolution. 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 SEC enforcement action or settlement 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 matters at this time. See Note 5 for further information.
	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 contract claim with the State in the total estimated amount of approximately $61 million on September 27, 2013 (Contract Claim #1). On February 14, 2014, the Company filed Contract Claim #1A, which amends Contract Claim #1, to a claim of approximately $34 million. The Company believes it has valid and reasonable factual and legal bases for Contract Claims #1 and 1A and that the circumstances that have led or will lead to the Company’s additional costs set forth in Contract Claims #1 and 1A 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 an appeal of the State's denial of Contract Claims #1 and 1A be litigated before the Maryland State Board of Contract Appeals (the Board).
	On February 19, 2014, the State provided a recommended decision denying Contract Claims #1 and 1A to the Company. The February 19, 2014 recommended decision was not a final agency determination on the claims. On April 29, 2014, the State provided a final decision, dated April 25, 2014, denying the claims to the Company. On May 28, 2014, the Company filed a Notice of Appeal with 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. The appeal is currently pending before the Board.
	On August 22, 2014, the State unilaterally suspended performance under the Contract for 90 days. On September 12, 2014, the State modified its August 22nd suspension of the Contract and authorized CSC, during the remainder of the 90-day suspension, to assign up to nine full-time-equivalent staff to perform various analyses of cost and schedule.
	As the result of the 90-day suspension and other actions and inactions by the State in performance of its obligations under and management of the Contract, the Company filed a second set of Claims with the Board (Claims #2A-D). Claim #2A, in the amount of $77 million, asserts that the Company's contractual undertaking did not include an agreement to receive reduced and delayed payments, and the State's unilateral imposition of such reductions and delays, together with the other factors are a cardinal change to the Contract entitling the Company to compensation for all costs incurred to date, including all liabilities incurred, and fee, as well as expected profit under the full contract. Alternatively, Claim #2B, in the amount of $65 million, asserts that the Maryland General Assembly's reduction to the appropriations for the MERP Project for fiscal 2015 effectively cancels the MERP Contract, entitling the Company to recover all costs incurred to date including all liabilities incurred, and a reasonable allowance for profit on costs and liabilities. Similarly, Claims #2C, also in the amount of $65 million, asserts that the State's actions, inactions, and decisions amount to a constructive termination for convenience entitling the Company to recover all costs incurred to date including, all liabilities incurred, and reasonable allowance for profit on costs and liabilities. Claim #2D is a claim for suspension costs during the 90-day period of $3 million, including labor costs, facilities costs and other costs needed to remain ready to re-start program. Due to the new claims, management conducted an additional assessment of any asset impairments if the contract terminates.
	On October 27, 2014, the United States District Court for the Southern District of New York unsealed a qui tam complaint that had been filed under seal over two years prior in a case entitled United States of America and State of New York ex rel. Vincent Forcier v. Computer Sciences Corporation and The City of New York, Case No. 1:12-cv-01750-DAB. The original complaint was brought by Vincent Forcier, a former employee of Computer Sciences Corporation, as a private party qui tam relator on behalf of the United States and the State of New York. The relator’s amended complaint, dated November 15, 2012, which remained under seal until October 27, 2014, alleged civil violations of the federal False Claims Act, 31 U.S.C. § 3729 et seq., and New York State’s False Claims Act, NY. Finance L, Art. 13, § 187 et seq., arising out of certain coding methods employed with respect to claims submitted by the Company to Medicaid for reimbursements as fiscal agent on behalf of its client, New York City’s Early Intervention Program (“EIP”). EIP is a federal program promulgated by the Individuals with Disabilities in Education Act, 20 U.S.C. § 1401 et seq. (“IDEA”), that provides early intervention services for infants and toddlers who have, or are likely to have, developmental delays.
	Prior to the unsealing of the complaint on October 27, 2014, the United States Attorney’s Office for the Southern District of New York investigated the allegations in the qui tam relator’s complaint. That investigation included requests for information to the Company concerning the Company’s databases, software programs, and related documents regarding EIP claims submitted by the Company on behalf of New York City. The Company produced documents and information that the government requested and cooperated fully with the government’s investigation regarding this matter at all times. In addition, the Company conducted its own investigation of the matter, and openly shared its findings and worked constructively with all parties to resolve the matter. At the conclusion of its investigation, the Company concluded that it had not violated the law in any respect.
	On October 27, 2014, the United States Attorney’s Office for the Southern District of New York and the Attorney General for the State of New York filed complaints-in-intervention on behalf of the United States and the State of New York, respectively. The complaints allege that, from 2008 to 2012, the Company and New York City used the automatic defaulting capabilities of a computerized billing system that the Company developed for New York City’s EIP in order to orchestrate a billing fraud against Medicaid. The New York Attorney General’s complaint also alleges that the Company did not comply with Medicaid requirements regarding submission of claims to private insurance and failed to reimburse Medicaid in certain instances where insurance had paid a portion of the claim. The lawsuits seek damages under the False Claims Act and common law theories in an amount equal to three times the sum of an unspecified amount of damages the United States and New York State allegedly sustained, plus civil penalties together with attorneys’ fees and costs. The Company believes that the allegations are without merit and intends to vigorously defend itself.
	Publicity surrounding the foregoing could have an adverse impact on the Company’s reputation, 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 matters at this time.
	In addition to the matters noted above, the Company is currently party to a number of disputes which involve or may involve litigation. The Company accrues a liability when management believes that it is both probable that a liability has been incurred and the amount of loss can be reasonably estimated under ASC 450. The Company believes it has appropriately recognized liabilities for any such matters. Regarding other matters that may involve actual or threatened disputes or litigation, the Company, in accordance with the applicable reporting requirements, provides disclosure of such matters for which the likelihood of material loss is at least reasonably possible.
	The Company also considered the requirements regarding estimates used in the disclosure of contingencies under ASC Subtopic 275-10, Risks and Uncertainties. Based on that guidance, the Company determined that supplemental accrual and disclosure was not required for a change in estimate that involve contingencies because the Company determined that it was not reasonably possible that a change in estimate will occur in the near term. The Company reviews contingencies during each interim period and adjusts its accruals to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case.
