Accounting Policies [Abstract]
ACCOUNTING POLICIES	NOTE A – ACCOUNTING POLICIES Basis of Presentation: The accompanying unaudited Condensed Consolidated Financial Statements of CA, Inc. (Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP), as defined in Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 270, for interim financial information and with the instructions to Rule 10-01 of Securities and Exchange Commission Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the Company’s Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2015 ( 2015 Form 10-K). In the opinion of management, all adjustments considered necessary for a fair presentation have been included. All such adjustments are of a normal, recurring nature. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Although these estimates are based on management’s knowledge of current events and actions it may undertake in the future, these estimates may ultimately differ from actual results. Operating results for the three and six months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2016 . Divestitures: In the second quarter of fiscal year 2015, the Company sold its CA arcserve data protection solution assets (arcserve). In the fourth quarter of fiscal year 2014, the Company identified its CA ERwin Data Modeling solution assets (ERwin) as available for sale. The results of operations associated with these businesses have been presented as discontinued operations in the accompanying Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Cash Flows. The effects of the discontinued operations were immaterial to the Company’s Condensed Consolidated Balance Sheets at September 30, 2015 and March 31, 2015 . See Note C, “Divestitures,” for additional information. Cash and Cash Equivalents: The Company’s cash and cash equivalents are held in numerous locations throughout the world, with approximately 78% being held by the Company’s foreign subsidiaries outside the United States at September 30, 2015 . New Accounting Pronouncements: In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers (Topic 606) , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In July 2015, the FASB issued a one-year deferral of the effective date of the new revenue recognition standard. The new standard will be effective for the Company's first quarter of fiscal year 2019 and early application for fiscal year 2018 would be permitted. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. ASU 2014-09 is expected to have a significant impact on the Company’s revenue recognition policies and disclosures. The Company has not yet selected a transition method nor has it determined when it will adopt the standard and the effect of the standard on its ongoing financial reporting.

Acquisitions

Business Combinations [Abstract]
ACQUISITIONS	NOTE B – ACQUISITIONS On July 8, 2015, the Company completed its acquisition of Rally Software Development Corp. (Rally), a provider of Agile development software and services. The acquisition of Rally broadens the Company’s solution set and capabilities to better serve customers in the application economy. Pursuant to the terms of the acquisition agreement and related tender offer, the Company acquired 100% of the outstanding shares of Rally common stock for approximately $519 million . The preliminary purchase price allocation for Rally is provided within the table below. The preliminary purchase price allocation for the Company’s other acquisitions during fiscal year 2016, including the second quarter acquisition of Xceedium, Inc. (Xceedium), is included within the “Other Fiscal Year 2016 Acquisitions” column below. The acquisition of Xceedium and the Company’s other acquisitions during fiscal year 2016 were immaterial, both individually and in the aggregate. (dollars in millions) Rally Other Fiscal Year 2016 Acquisitions Estimated Useful Life Finite-lived intangible assets (1) $ 78 $ 14 1-15 years Purchased software 190 93 5-7 years Goodwill 256 60 Indefinite Deferred tax liabilities, net (56 ) (23 ) — Other assets net of other liabilities assumed (2) 51 2 — Purchase price $ 519 $ 146 (1) Includes customer relationships and trade names. (2) Includes approximately $13 million of cash acquired and approximately $48 million of short-term investments acquired relating to Rally. The excess purchase price over the estimated value of the net tangible and identifiable intangible assets was recorded to goodwill. The preliminary allocation of the purchase price to goodwill was predominantly due to synergies the Company expects to achieve through integration of the acquired technology with the Company’s existing product portfolio and the intangible assets that are not separable, such as assembled workforce and going concern. The goodwill relating to the Company’s acquisition of Rally is not expected to be deductible for tax purposes and is allocated to the Enterprise Solutions segment. The allocation of purchase price to acquired identifiable assets, including intangible assets, is preliminary due to the ongoing analysis to determine the fair value of acquired intangibles and the tax basis of acquired assets and liabilities. The goodwill relating to the Company’s other fiscal year 2016 acquisitions is not expected to be deductible for tax purposes and is allocated to the Enterprise Solutions segment. Transaction costs for the Company’s fiscal year 2016 acquisitions, which are primarily included in “General and administrative” in the Company’s Condensed Consolidated Statements of Operations, were $17 million and $20 million for the three and six months ended September 30, 2015 , respectively. The pro forma effects of the Company’s fiscal year 2016 acquisitions on the Company’s revenues and results of operations during fiscal years 2016 and 2015 were considered immaterial. The Condensed Consolidated Statements of Operations for the three and six months ended September 30, 2015 included total revenue of $25 million and net loss of $13 million since the date of acquisition through September 30, 2015 for the Company’s fiscal year 2016 acquisitions of Rally and Xceedium. Revenues and results of operations since the date of acquisition for the Company’s other fiscal 2016 acquisitions were considered immaterial. The Company had approximately $7 million and $27 million of accrued acquisition-related costs at September 30, 2015 and March 31, 2015 , respectively, related to purchase price amounts withheld subject to indemnification protections.

Discontinued Operations and Disposal Groups [Abstract]
DIVESTITURES	NOTE C – DIVESTITURES In the second quarter of fiscal year 2015, the Company sold arcserve for approximately $170 million and recognized a gain on disposal of approximately $20 million , including tax expense of approximately $77 million . The effective tax rate on the disposal was unfavorably affected by non-deductible goodwill of approximately $109 million . In the fourth quarter of fiscal year 2014, the Company identified ERwin as available for sale. The divestiture of arcserve and the planned divestiture of ERwin result from an effort to rationalize the Company’s product portfolio within the Enterprise Solutions segment. The income from discontinued operations relating to both ERwin and the sale of arcserve for the three and six months ended September 30, 2015 and 2014 consisted of the following: Three Months Ended (in millions) 2015 2014 Subscription and maintenance $ 5 $ 10 Software fees and other 2 5 Total revenue $ 7 $ 15 Income from operations of discontinued components, net of tax expense of $2 million and $2 million, respectively $ 2 $ 1 Gain on disposal of discontinued component, net of tax — 20 Income from discontinued operations, net of tax $ 2 $ 21 Six Months Ended (in millions) 2015 2014 Subscription and maintenance $ 11 $ 31 Software fees and other 4 15 Total revenue $ 15 $ 46 Income from operations of discontinued components, net of tax expense of $4 million and $6 million, respectively $ 7 $ 6 Gain on disposal of discontinued component, net of tax — 20 Income from discontinued operations, net of tax $ 7 $ 26

These evaluations require complex assumptions about key factors such as future customer demand, technology trends and the impact of those factors on the technology the Company acquires and develops for its products. Impairments or revisions to useful lives could result from the use of alternative assumptions that reflect reasonably possible outcomes related to future customer demand or technology trends for assets within the Enterprise Solutions segment.

Debt Disclosure [Abstract]
DEBT	NOTE H – DEBT Senior Notes: In August 2015, the Company issued $400 million of 3.600% Senior Notes due August 2020 (3.600% Notes) for proceeds of approximately $400 million , reflecting a discount of less than $1 million . The 3.600% Notes are senior unsecured obligations that rank equally in right of payment with all of the Company’s existing and future unsecured and unsubordinated obligations and are redeemable by the Company at any time, subject to a “make-whole” premium of 30 basis points. Interest on the 3.600% Notes is payable semiannually in February and August, beginning February 2016. In the event of a change of control, each note holder will have the right to require the Company to repurchase all or any part of the holder’s 3.600% Notes in cash at a price equal to 101% of the principal amount of such 3.600% Notes plus accrued and unpaid interest, if any, to the date of repurchase. This is subject to the right of holders of record on the relevant interest payment date to receive interest due. The 3.600% Notes contain customary covenants and events of default. The maturity of the 3.600% Notes may be accelerated by holders upon certain events of default, including failure to make payments when due and failure to comply with covenants. The Company capitalized transaction costs of approximately $3 million associated with the 3.600% Notes and will amortize these costs to “Interest expense, net” in the Company's Condensed Consolidated Statements of Operations. Revolving Credit Facility: In April 2015, the Company amended its revolving credit facility to extend the termination date from June 2018 to June 2019. The maximum committed amount available under the revolving credit facility is $1 billion . The facility also provides the Company with an option to increase the available credit by an amount up to $500 million . This option is subject to certain conditions and the agreement of the facility lenders. The Company capitalized transaction costs of less than $1 million associated with the April 2015 amendment of the revolving credit facility. These fees are being amortized to “Interest expense, net” in the Company’s Condensed Consolidated Statements of Operations. In July 2015 and in connection with the acquisition of Rally, the Company borrowed $400 million under its revolving credit facility. The interest rate applicable to the Company at the time of borrowing under the revolving credit facility was approximately 1.19% . In August 2015, the Company repaid the $400 million borrowing under its revolving credit facility with proceeds received from the Company’s issuance of the 3.600% Notes described above. Interest expense in connection with the borrowing under the revolving credit facility was less than $1 million for the three and six months ended September 30, 2015 . At September 30, 2015 and March 31, 2015 , there were no outstanding borrowings under the revolving credit facility. For additional information concerning the Company’s debt obligations, refer to the Company’s Consolidated Financial Statements and Notes thereto included in the Company’s 2015 Form 10-K.

Changes in interest rates could affect the Company’s monetary assets and liabilities, and foreign exchange rate changes could affect the Company’s foreign currency denominated monetary assets and liabilities and forecasted transactions. The Company enters into derivative contracts with the intent of mitigating a portion of these risks. Interest Rate Swaps: At September 30, 2015 and March 31, 2015 , the Company had no interest rate swap derivatives outstanding. Foreign Currency Contracts: The Company enters into foreign currency option and forward contracts to manage foreign currency risks. The Company has not designated its foreign exchange derivatives as hedges. Accordingly, changes in fair value from these contracts are recorded as “Other expenses, net” in the Company’s Condensed Consolidated Statements of Operations. At September 30, 2015 , foreign currency contracts outstanding consisted of purchase and sale contracts with a total gross notional value of approximately $1,338 million and durations of less than six months . The net fair value of these contracts at September 30, 2015 was a net asset of approximately $7 million , of which approximately $19 million is included in “Other current assets” and approximately $12 million is included in “Accrued expenses and other current liabilities” in the Company’s Condensed Consolidated Balance Sheet. At March 31, 2015 , foreign currency contracts outstanding consisted of purchase and sale contracts with a total gross notional value of approximately $298 million and durations of less than three months . The net fair value of these contracts at March 31, 2015 was a net asset of approximately $2 million , of which approximately $5 million is included in “Other current assets” and approximately $3 million is included in “Accrued expenses and other current liabilities” in the Company’s Condensed Consolidated Balance Sheet. A summary of the effect of the interest rate and foreign exchange derivatives on the Company’s Condensed Consolidated Statements of Operations was as follows: Amount of Net (Gain)/Loss Recognized in the Condensed Consolidated Statements of Operations Three Months Ended Six Months Ended (in millions) 2015 2014 2015 2014 Interest expense, net – interest rate swaps designated as fair value hedges $ — $ (3 ) $ — $ (6 ) Other expenses, net – foreign currency contracts $ (8 ) $ (17 ) $ 3 $ (12 ) The Company is subject to collateral security arrangements with most of its major counterparties. These arrangements require the Company or the counterparty to post collateral when the derivative fair values exceed contractually established thresholds. The aggregate fair values of all derivative instruments under these collateralized arrangements were either in a net asset position or under the established threshold at September 30, 2015 and March 31, 2015 . The Company posted no collateral at September 30, 2015 or March 31, 2015 . Under these agreements, if the Company’s credit ratings had been downgraded one rating level, the Company would still not have been required to post collateral.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE K – COMMITMENTS AND CONTINGENCIES The Company, various subsidiaries, and certain current and former officers have been or, from time to time, may be named as defendants in various lawsuits and claims arising in the normal course of business. The Company may also become involved with contract issues and disputes with customers, including government customers. On March 24, 2014, the U.S. Department of Justice (DOJ) filed under seal in the United States District Court for the District of Columbia a complaint against the Company in partial intervention under the qui tam provisions of the civil False Claims Act (FCA). The underlying complaint was filed under seal by an individual plaintiff on August 24, 2009. On May 29, 2014, the case was unsealed. Both the DOJ and the individual plaintiff have filed amended complaints. The current complaints relate to government sales transactions under the Company’s General Services Administration (GSA) schedule contract, entered into in 2002 and extended until present through subsequent amendments. In sum and substance, the current complaints allege that the Company provided inaccurate commercial discounting information to the GSA during contract negotiations and that, as a result, the GSA’s contract discount was lower than it otherwise would have been. In addition, the complaints allege that the Company failed to apply the full negotiated discount in some instances and to pay sufficient rebates pursuant to the contract’s price reduction clause. In addition to FCA claims, the current complaints also assert common law causes of action. The DOJ complaint seeks an unspecified amount of damages, including treble damages and civil penalties. The complaint by the individual plaintiff alleges that the U.S. government has suffered damages in excess of $100 million and seeks an unspecified amount of damages, including treble damages and civil penalties. The Company filed motions to dismiss the current complaints. On March 31, 2015, the court issued decisions denying the Company's motion to dismiss the DOJ complaint, and granting in part and denying in part the Company's motion to dismiss the individual plaintiff's complaint. The discovery phase of the case is scheduled to conclude in April 2016. On October 30, 2014, the GSA Suspension and Debarment Division issued a Show Cause Letter to the Company in response to the complaints summarized above. In sum, the letter called on the Company to demonstrate why the U.S. government should continue to contract with the Company, given the litigation allegations made in these complaints. On December 19, 2014, the Company provided a detailed response to the Show Cause Letter. In July 2015, after the Company agreed to assume certain additional reporting requirements during the pendency of the litigation, the GSA Suspension and Debarment Division advised the Company that it had concluded its review and determined that the Company is a responsible contractor with which government agencies could continue to contract. The Company cannot predict the amount of damages likely to result from the litigation summarized above. Although the timing and ultimate outcome of this litigation cannot be determined, the Company believes that the material aspects of the liability theories set forth in the litigation complaints are unfounded. The Company also believes that it has meritorious defenses and intends to vigorously contest the lawsuit. Based on the Company’s experience, management believes that the damages amounts claimed in a case are not a meaningful indicator of the potential liability. Claims, suits, investigations and proceedings are inherently uncertain and it is not possible to predict the ultimate outcome of cases. The Company believes that it has meritorious defenses in connection with its current lawsuits and material claims and disputes, and intends to vigorously contest each of them. In the opinion of the Company’s management based upon information currently available to the Company, while the outcome of these lawsuits, claims and disputes is uncertain, the likely results of these lawsuits, claims and disputes are not expected, either individually or in the aggregate, to have a material adverse effect on the Company’s financial position, results of operations or cash flows, although the effect could be material to the Company’s results of operations or cash flows for any interim reporting period. For some of these matters, the Company is unable to estimate a range of reasonably possible loss due to the stage of the matter and/or other particular circumstances of the matter. For others, a range of reasonably possible loss can be estimated. For those matters for which such a range can be estimated, the Company estimates that, in the aggregate, the range of reasonably possible loss is from zero to $40 million . This is in addition to amounts, if any, that have been accrued for those matters. The Company is obligated to indemnify its officers and directors under certain circumstances to the fullest extent permitted by Delaware law. As a part of that obligation, the Company may, from time to time, advance certain attorneys’ fees and expenses incurred by officers and directors in various lawsuits and investigations, as permitted under Delaware law.

Earnings Per Share [Abstract]
INCOME FROM CONTINUING OPERATIONS PER COMMON SHARE	NOTE M – INCOME FROM CONTINUING OPERATIONS PER COMMON SHARE Basic net income per common share excludes dilution and is calculated by dividing net income allocable to common shares by the weighted average number of common shares outstanding for the period. Diluted net income per common share is calculated by dividing net income allocable to common shares by the weighted average number of common shares, as adjusted for the potential dilutive effect of non-participating share-based awards. The following table presents basic and diluted income from continuing operations per common share information for the three and six months ended September 30, 2015 and 2014 : Three Months Ended Six Months Ended 2015 2014 2015 2014 (in millions, except per share amounts) Basic income from continuing operations per common share: Income from continuing operations $ 172 $ 235 $ 379 $ 447 Less: Income from continuing operations allocable to participating securities (2 ) (2 ) (4 ) (4 ) Income from continuing operations allocable to common shares $ 170 $ 233 $ 375 $ 443 Weighted average common shares outstanding 436 440 436 440 Basic income from continuing operations per common share $ 0.39 $ 0.53 $ 0.86 $ 1.01 Diluted income from continuing operations per common share: Income from continuing operations $ 172 $ 235 $ 379 $ 447 Less: Income from continuing operations allocable to participating securities (2 ) (2 ) (4 ) (4 ) Income from continuing operations allocable to common shares $ 170 $ 233 $ 375 $ 443 Weighted average shares outstanding and common share equivalents: Weighted average common shares outstanding 436 440 436 440 Weighted average effect of share-based payment awards 1 1 1 1 Denominator in calculation of diluted income per share 437 441 437 441 Diluted income from continuing operations per common share $ 0.39 $ 0.53 $ 0.86 $ 1.00 For the three months ended September 30, 2015 and 2014 , respectively, approximately 2 million and 2 million shares of Company common stock underlying restricted stock awards and options to purchase common stock were excluded from the calculation because their effect on income per share was anti-dilutive during the respective periods. Weighted average restricted stock awards of approximately 5 million and 5 million for the three months ended September 30, 2015 and 2014 , respectively, were considered participating securities in the calculation of net income allocable to common stockholders. For the six months ended September 30, 2015 and 2014 , respectively, approximately 2 million and 2 million shares of Company common stock underlying restricted stock awards and options to purchase common stock were excluded from the calculation because their effect on income per share was anti-dilutive during the respective periods. Weighted average restricted stock awards of approximately 4 million and 4 million for the six months ended September 30, 2015 and 2014 , respectively, were considered participating securities in the calculation of net income allocable to common stockholders.

The value of performance share units (PSUs) is determined using the closing price of the Company’s common stock on the last trading day of the quarter until the awards are granted. Compensation costs for the PSUs are amortized over the requisite service periods based on the expected level of achievement of the performance targets. At the conclusion of the performance periods for the PSUs, the applicable number of shares of common stock, restricted stock awards (RSAs) or restricted stock units (RSUs) granted may vary based upon the level of achievement of the performance targets and the approval of the Company’s Compensation and Human Resources Committee (which may reduce any award for any reason in its discretion). For the six months ended September 30, 2015 and 2014 , the Company issued stock options for approximately 0.9 million shares and 0.6 million shares, respectively. The weighted average fair values and assumptions used for the options granted were as follows: Six Months Ended 2015 2014 Weighted average fair value $ 4.68 $ 5.87 Dividend yield 3.37 % 3.29 % Expected volatility factor (1) 23 % 29 % Risk-free interest rate (2) 1.9 % 2.1 % Expected life (in years) (3) 6.0 6.0 (1) Expected volatility is measured using historical daily price changes of the Company’s stock over the respective expected term of the options and the implied volatility derived from the market prices of the Company’s traded options. (2) The risk-free rate for periods within the contractual term of the stock options is based on the U.S. Treasury yield curve in effect at the time of grant. (3) The expected life is the number of years the Company estimates that options will be outstanding prior to exercise. The Company’s computation of expected life was determined based on the simplified method (the average of the vesting period and option term). The table below summarizes the RSAs and RSUs granted under the 1-year PSUs for the Company’s fiscal year 2015 and 2014 incentive plan years. The RSAs and RSUs were granted in the first quarter of fiscal years 2016 and 2015 , respectively. The RSAs and RSUs vest 34% on the date of grant and 33% on the first and second anniversaries of the grant date.

The ESPP offer period is semi-annual and allows participants to purchase the Company’s common stock at 95% of the closing price of the stock on the last day of the offer period. The ESPP is non-compensatory. For the six-month offer period ended June 30, 2015 , the Company issued approximately 0.1 million shares under the ESPP at $27.83 per share.

INCOME TAXES	NOTE O – INCOME TAXES Income tax expense for the three and six months ended September 30, 2015 was approximately $75 million and $163 million , respectively, compared with income tax expense for the three and six months ended September 30, 2014 of approximately $73 million and $160 million , respectively. For the three and six months ended September 30, 2014, the Company recognized a discrete tax benefit of approximately $19 million resulting from the resolutions of uncertain tax positions upon the completion of the examination of the Company's U.S. federal income tax returns for the tax years ended March 31, 2012 and 2011. The Company’s estimated annual effective tax rate, which excludes the impact of discrete items, for the six months ended September 30, 2015 and 2014 was 29.6% and 29.2% , respectively. Changes in tax laws, the outcome of tax audits and any other changes in potential tax liabilities may result in additional tax expense or benefit in fiscal year 2016 , which are not considered in the Company’s estimated annual effective tax rate. While the Company does not currently view any such items as individually material to the results of the Company’s consolidated financial position or results of operations, the impact of certain items may yield additional tax expense or benefit in the remaining quarters of fiscal year 2016 and the Company is anticipating a fiscal year 2016 effective tax rate between 28% and 29% .

For the six months ended September 30, 2015 and 2014 , the excess tax benefits from share-based incentive awards included in financing activities from continuing operations were approximately $3 million and $3 million , respectively. Non-cash financing activities for the six months ended September 30, 2015 and 2014 consisted of treasury common shares issued in connection with the following: share-based incentive awards issued under the Company’s equity compensation plans of approximately $41 million (net of approximately $27 million of income taxes withheld) and $42 million (net of approximately $27 million of income taxes withheld), respectively; and discretionary stock contributions to the CA, Inc. Savings Harvest Plan of approximately $24 million and $26 million , respectively. Non-cash financing activities for the six months ended September 30, 2015 and 2014 included approximately $2 million and $3 million , respectively, in treasury common shares issued in connection with the Company’s Employee Stock Purchase Plan. The Company uses a notional pooling arrangement with an international bank to help manage global liquidity. Under this pooling arrangement, the Company and its participating subsidiaries may maintain either cash deposit or borrowing positions through local currency accounts with the bank, so long as the aggregate position of the global pool is a notionally calculated net cash deposit. Because it maintains a security interest in the cash deposits and has the right to offset the cash deposits against the borrowings, the bank provides the Company and its participating subsidiaries favorable interest terms on both. The activity under this notional pooling arrangement for the six months ended September 30, 2015 and 2014 was as follows: Six Months Ended 2015 2014 (in millions) Total borrowings outstanding at beginning of period (1) $ 138 $ 139 Borrowings 2,494 2,703 Repayments (2,497 ) (2,647 ) Foreign exchange effect 4 (56 ) Total borrowings outstanding at end of period (1) $ 139 $ 139 (1) Included in “Accrued expenses and other current liabilities” in the Company’s Condensed Consolidated Balance Sheets.

Segment Reporting [Abstract]
SEGMENT INFORMATION	NOTE Q – SEGMENT INFORMATION The Company’s Mainframe Solutions and Enterprise Solutions segments comprise its software business organized by the nature of the Company’s software offerings and the platform on which the products operate. The Services segment comprises product implementation, consulting, customer education and customer training, including those directly related to the Mainframe Solutions and Enterprise Solutions software that the Company sells to its customers. Segment expenses do not include share-based compensation expense; amortization of purchased software; amortization of other intangible assets; certain foreign exchange derivative hedging gains and losses; charges relating to rebalancing initiatives that are large enough to require approval from the Company’s Board of Directors ( i.e., costs associated with the Company’s Fiscal 2014 Plan); and other miscellaneous costs. The Company considers all costs of internally developed software as segment expense in the period the costs are incurred and as a result, the Company excludes amortization of internally developed software costs previously capitalized from segment expenses. A measure of segment assets is not currently provided to the Company’s Chief Executive Officer and has therefore not been disclosed. The Company’s segment information for the three and six months ended September 30, 2015 and 2014 was as follows: Three Months Ended September 30, 2015 Mainframe Solutions Enterprise Solutions Services Total (dollars in millions) Revenue $ 554 $ 368 $ 83 $ 1,005 Expenses 212 357 79 648 Segment profit $ 342 $ 11 $ 4 $ 357 Segment operating margin 62 % 3 % 5 % 36 % Depreciation $ 9 $ 6 $ — $ 15 Reconciliation of segment profit to income from continuing operations before income taxes for the three months ended September 30, 2015 : (in millions) Segment profit $ 357 Less: Purchased software amortization 39 Other intangibles amortization 14 Internally developed software products amortization 28 Share-based compensation expense 23 Other gains, net (1) (6 ) Interest expense, net 12 Income from continuing operations before income taxes $ 247 (1) Other gains, net consists of costs associated with certain foreign exchange derivative hedging gains and losses, and other miscellaneous costs.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying unaudited Condensed Consolidated Financial Statements of CA, Inc. (Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP), as defined in Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 270, for interim financial information and with the instructions to Rule 10-01 of Securities and Exchange Commission Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the Company’s Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2015 ( 2015 Form 10-K). In the opinion of management, all adjustments considered necessary for a fair presentation have been included. All such adjustments are of a normal, recurring nature. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Although these estimates are based on management’s knowledge of current events and actions it may undertake in the future, these estimates may ultimately differ from actual results. Operating results for the three and six months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2016 .
Divestitures	Divestitures: In the second quarter of fiscal year 2015, the Company sold its CA arcserve data protection solution assets (arcserve). In the fourth quarter of fiscal year 2014, the Company identified its CA ERwin Data Modeling solution assets (ERwin) as available for sale. The results of operations associated with these businesses have been presented as discontinued operations in the accompanying Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Cash Flows. The effects of the discontinued operations were immaterial to the Company’s Condensed Consolidated Balance Sheets at September 30, 2015 and March 31, 2015 . See Note C, “Divestitures,” for additional information.
Cash and Cash Equivalents	Cash and Cash Equivalents: The Company’s cash and cash equivalents are held in numerous locations throughout the world, with approximately 78% being held by the Company’s foreign subsidiaries outside the United States at September 30, 2015 .
New Accounting Pronouncements	New Accounting Pronouncements: In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers (Topic 606) , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In July 2015, the FASB issued a one-year deferral of the effective date of the new revenue recognition standard. The new standard will be effective for the Company's first quarter of fiscal year 2019 and early application for fiscal year 2018 would be permitted. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. ASU 2014-09 is expected to have a significant impact on the Company’s revenue recognition policies and disclosures. The Company has not yet selected a transition method nor has it determined when it will adopt the standard and the effect of the standard on its ongoing financial reporting.

Finite-Lived Intangible Assets
Uncertainty, Continued marketability of goods and services	The Company evaluates the useful lives and recoverability of capitalized software and other intangible assets when events or changes in circumstances indicate that an impairment may exist. These evaluations require complex assumptions about key factors such as future customer demand, technology trends and the impact of those factors on the technology the Company acquires and develops for its products. Impairments or revisions to useful lives could result from the use of alternative assumptions that reflect reasonably possible outcomes related to future customer demand or technology trends for assets within the Enterprise Solutions segment.
