Basis of Presentation and Summary of Significant Accounting Policies [Text Block]	'
	1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	The accompanying Condensed Consolidated Financial Statements have been prepared by NCR Corporation (NCR, the Company, we or us) without audit pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC) and, in the opinion of management, include all adjustments (consisting of normal, recurring adjustments, unless otherwise disclosed) necessary for a fair statement of the consolidated results of operations, financial position, and cash flows for each period presented. The consolidated results for the interim periods are not necessarily indicative of results to be expected for the full year. The 2012 year-end Condensed Consolidated Balance Sheet was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States (GAAP). These financial statements should be read in conjunction with NCR’s Form 10-K for the year ended December 31, 2012.
	On February 6, 2013, the Company completed the acquisition of Retalix Ltd. (Retalix). As a result of the acquisition, the results of Retalix are included for the period from February 6, 2013 to September 30, 2013. See Note 4, "Acquisitions," for additional information.
	Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates.
	Evaluation of Subsequent Events The Company evaluated subsequent events through the date that our Condensed Consolidated Financial Statements were issued. Except as described below, no matters were identified that required adjustment of the Condensed Consolidated Financial Statements or additional disclosure.
	Employee Benefit Plans On October 1, 2013, the Company made a $100 million discretionary contribution to the U.S. qualified pension plan.
	Reclassifications Certain prior-period amounts have been reclassified in the accompanying Condensed Consolidated Financial Statements and Notes thereto in order to conform to the current period presentation.
	Related Party Transactions In 2011, concurrent with the sale of a noncontrolling interest in our subsidiary, NCR Brasil - Indústria de Equipamentos para Automação S.A., to Scopus Tecnologia Ltda. (Scopus), we entered into a Master Purchase Agreement (MPA) with Banco Bradesco SA (Bradesco), the parent of Scopus. Through the MPA, Bradesco agreed to purchase up to 30,000 ATMs from us over the 5-year term of the agreement. Pricing of the ATMs will adjust over the term of the MPA using certain formulas which are based on prevailing market pricing. We recognized revenue related to Bradesco totaling $24 million and $101 million during the three and nine months ended September 30, 2013, respectively, as compared to $40 million and $95 million during the three and nine months ended September 30, 2012, respectively. As of September 30, 2013 and December 31, 2012, we had $17 million and $9 million, respectively, in receivables outstanding from Bradesco.
	Recent Accounting Pronouncements
	Adopted
	In February 2013, the Financial Accounting Standards Board (FASB) issued an accounting standards update requiring new disclosures about reclassifications from accumulated other comprehensive loss to net income. These disclosures may be presented on the face of the consolidated financial statements or in the notes thereto. The standards update is effective for fiscal years beginning after December 15, 2012. We adopted this standards update and included the additional disclosure, as required, in the first quarter of 2013. See Note 16, "Accumulated Other Comprehensive Income (Loss)," for additional information.
	Issued
	In February 2013, the FASB issued changes to the accounting for obligations resulting from joint and several liability arrangements. These changes require an entity to measure those joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. The total amount of the obligation is determined as the sum of (i) the amount the reporting entity agreed to pay on the basis of its arrangement with its co-obligors, and (ii) any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance also requires an entity to disclose the nature and amount of the obligation as well as other information about the obligation. Examples of obligations subject to these requirements include debt arrangements, settled litigation and judicial rulings. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, with early adoption permitted. The implementation of the amended accounting guidance on January 1, 2014 is not expected to have a material impact on our consolidated financial statements.
	In March 2013, the FASB issued amendments to address the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The amendments are effective prospectively for fiscal years, and interim reporting periods within those years, beginning after December 15, 2013, with early adoption permitted. The initial adoption on January 1, 2014 is not expected to have a material impact on our consolidated financial statements.

Pension Benefit Plan Accounting Methodology Changes	'
	2. PENSION BENEFIT PLAN ACCOUNTING METHODOLOGY CHANGES
	Effective in the first quarter of 2013, we elected to change our accounting methodology for recognizing costs for all of our company-sponsored U.S. and international pension benefit plans. Previously, net actuarial gains or losses (except those differences not yet reflected in the market-related value) were only amortized to the extent that they exceeded 10% of the higher of the market-related value or the projected benefit obligation of each respective plan. Beginning in 2012, the losses associated with the U.S. qualified pension plan and our largest UK pension plan were amortized over the expected remaining lifetime of plan participants instead of the expected service period of active plan participants, because almost all of the participants were inactive. For our other U.S. and international plans, the gains or losses were amortized over the expected service period of the active plan participants. Further, the expected return on plan assets component of pension expense for our U.S. pension plan was previously determined using the expected rate of return and a calculated value of assets, referred to as the “market-related value.” Differences between the assumed and actual returns were reflected in market-related value on a straight-line basis over a 5-year period. Differences in excess of 10% of the market value were recognized immediately. Similar approaches were employed in determining expense for NCR's international plans.
	Under our new accounting methods, we will recognize changes in the fair value of plan assets and net actuarial gains or losses upon remeasurement, which is at least annually in the fourth quarter of each year. These new accounting methods will result in changes in the fair value of plan assets and net actuarial gains and losses being recognized in expense faster than under our previous amortization method. The remaining components of pension expense, primarily net service cost, interest cost, and the expected return on plan assets, will be recorded on a quarterly basis as ongoing pension expense. While our previous policy of recognizing pension expense was acceptable, we believe that these new policies are preferable as they accelerate the recognition in our operating results of changes in the fair value of plan assets and actuarial gains and losses.
	These changes have been reported through retrospective application of the new policies to all periods presented.
	In its Quarterly Reports on Form 10-Q for the quarters ended March 31 and June 30, 2013, the Company reported that it recorded a cumulative reduction of retained earnings as of December 31, 2012 (the most recent measurement date prior to the change) of $1,050 million related to these changes in accounting methodology. However, during the third quarter of 2013, the Company determined that there was an error in the calculation of the cumulative reduction of retained earnings as of December 31, 2012 under the new method of accounting that did not affect total stockholders' equity but required an adjustment between retained earnings and accumulated other comprehensive loss. As a result, the previously reported cumulative reduction in retained earnings as of December 31, 2012 should instead have been $1,205 million. The December 31, 2012 retained earnings and accumulated other comprehensive income balances set forth in this Quarterly Report on Form 10-Q reflect the correction of this error as well as an adjustment to the retained earnings balance to reflect a change in the value of plan assets. These adjustments also impact the Company’s previously reported retained earnings and accumulated other comprehensive income balances for the first and second quarter of 2013. The impact of the these adjustments on the Company’s previously reported retained earnings and comprehensive income balances for and March 31, and June 30, 2013 is as follows:
		30-Jun-13						31-Mar-13
	Condensed Consolidated Balance Sheets (Unaudited):	Previously Reported			Revised			Previously Reported			Revised
	Retained earnings	1,231			1,076			1,145			990
	Accumulated other comprehensive loss	(222	)		(62	)		(192	)		(32	)
	The revised adjustment does not impact the Company’s Condensed Statement of Operations, of Comprehensive Income or of Cash Flows for the first or second quarter of 2013, or for the nine months ended September 30, 2013. The Company has determined that the impact of the adjustments was not material to its previously reported interim 2013 financial statements.
	The impact of all adjustments made to the financial statements presented resulting of the change in accounting methodology is summarized below (amounts in millions, except per share data):

Acquisitions	'
	4. ACQUISITIONS
	Acquisition of Retalix Ltd. On February 6, 2013, NCR completed its acquisition of Retalix, for which it paid an aggregate cash purchase price of $791 million which includes $3 million to be recognized as compensation expense within selling, general and administrative expenses over a period of approximately three years from the acquisition date. The purchase price was paid from the net proceeds of the December 2012 offer and sale of NCR's 4.625% senior unsecured notes and borrowing under NCR's senior secured credit facility. As a result of the acquisition, Retalix became an indirect wholly owned subsidiary of NCR.
	Retalix is a leading global provider of innovative retail software and services that transact billions of dollars in annual retail sales across its platform. The acquisition is consistent with NCR's continued transformation to a hardware-enabled, software-driven business. Retalix's strength with blue-chip retailers is highly complementary and provides additional sales opportunities across the combined installed base.
	Recording of Assets Acquired and Liabilities Assumed
	The fair value of consideration transferred to acquire Retalix was allocated to the identifiable assets acquired and liabilities assumed based upon their estimated fair market values as of the date of the acquisition as set forth below. The Company's purchase price allocation for Retalix is preliminary and subject to revision as additional information about fair value of the assets and liabilities becomes available. Additional information that existed as of the acquisition date but at that time was unknown to the Company, may become known to the Company during the remainder of the measurement period, a period not to exceed 12 months from the acquisition date. Adjustments in the purchase price allocation may require a recasting of the amounts allocated to goodwill retroactive to the period in which the acquisition occurred.
	The adjusted preliminary allocation of the purchase price for Retalix is as follows:
	In millions	Fair Value
	Cash and cash equivalents	$	127
	Accounts receivable	107
	Other tangible assets	60
	Acquired goodwill	452
	Acquired intangible assets other than goodwill	205
	Deferred tax liabilities	(43		)
	Liabilities assumed	(120		)
	Total purchase consideration	$	788
	Goodwill represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The goodwill arising from the acquisition consists of the margin and cost synergies expected from combining the operations of NCR and Retalix. It is expected that approximately $35 million of the goodwill recognized in connection with the acquisition will be deductible for tax purposes. The goodwill arising from the acquisition has been allocated to the Retail Solutions segment. Refer to Note 5, "Goodwill and Purchased Intangible Assets" for the carrying amounts of goodwill by segment as of September 30, 2013.
	The intangible assets acquired in the acquisition include the following:
			Estimated		Weighted Average Amortization Period(1)
			Fair Value
		(In millions)			(years)
	Direct customer relationships		$	121	20
	Technology - Software		74		5
	Trademarks		10		6
	Total acquired intangible assets		$	205	14
	(1)	Determination of the weighted average amortization period of the individual categories of intangible assets was based on the nature of the applicable intangible asset and the expected future cash flows to be derived from the intangible asset. Amortization of intangible assets with definite lives is recognized over the period of time the assets are expected to contribute to future cash flows.
	The Company has incurred a total of $9 million of transaction expenses to date relating to the acquisition, of which $6 million are included in selling, general and administrative expenses in the Company's Condensed Consolidated Statement of Operations for the nine months ended September 30, 2013.

	As of September 30, 2013, the Company’s total debt was $2.23 billion, with $15 million included in short-term borrowings and $2.21 billion included in long-term debt, as follows:
	In millions	30-Sep-13		31-Dec-12

	Total debt	$	2,227	$	1,963
	Senior Secured Credit Facility On July 25, 2013, the Company amended and restated its senior secured credit facility with and among the lenders party thereto and JPMorgan Chase Bank, N.A., as the administrative agent, and refinanced its term loan facility and revolving credit facility thereunder (Senior Secured Credit Facility). The Senior Secured Credit Facility now consists of a term loan facility in an aggregate principal amount of $1.12 billion, and a revolving credit facility in an aggregate principal amount of $850 million. The revolving credit facility also allows a portion of the availability to be used for outstanding letters of credit, and as of September 30, 2013, outstanding letters of credit totaled approximately $17 million. The Company deferred approximately $9 million in additional debt issuance costs which are being amortized to interest expense over the life of the debt.
	The outstanding principal balance of the term loan facility is required to be repaid in equal quarterly installments in annual amounts equal to 5.0% of the original amount of the term loans beginning September 30, 2014, 7.5% of the original amount of the term loans beginning September 30, 2015, and 10.0% of the original amount of the term loans beginning September 30, 2016, with the balance being due at maturity on July 25, 2018. Borrowings under the revolving portion of the credit facility are due July 25, 2018. Amounts outstanding under the Senior Secured Credit Facility bear interest, at the Company's option, at a base rate equal to the highest of (i) the federal funds rate plus 0.50%, (ii) the administrative agent's “prime rate” and (iii) the one-month LIBOR rate plus 1.00% (the Base Rate) or LIBOR, plus a margin ranging from 0.25% to 1.25% for Base Rate-based loans that are either term loans or revolving loans and ranging from 1.25% to 2.25% for LIBOR-based loans that are either term loans or revolving loans, depending on the Company's consolidated leverage ratio. The terms of the Senior Secured Credit Facility also require certain other fees and payments to be made by the Company, including a commitment fee on the undrawn portion of the revolving credit facility.
	The Company's obligations under the Senior Secured Credit Facility are guaranteed by certain of its wholly-owned domestic subsidiaries. The Senior Secured Credit Facility and these guarantees are secured by a first priority lien and security interest in certain equity interests owned by the Company and the guarantor subsidiaries in certain of their respective domestic and foreign subsidiaries. These security interests would be released if the Company achieves an “investment grade” rating, and will remain released so long as the Company maintains that rating.
	The Senior Secured Credit Facility includes affirmative and negative covenants that restrict or limit the ability of the Company and its subsidiaries to, among other things, incur indebtedness; create liens on assets; engage in certain fundamental corporate changes or changes to the Company's business activities; make investments; sell or otherwise dispose of assets; engage in sale-leaseback or hedging transactions; repurchase stock, pay dividends or make similar distributions; repay other indebtedness; engage in certain affiliate transactions; or enter into agreements that restrict the Company's ability to create liens, pay dividends or make loan repayments. The Senior Secured Credit Facility also includes financial covenants that require us to maintain:
	•	a consolidated leverage ratio on the last day of any fiscal quarter, not to exceed (i) in the case of any fiscal quarter ending on or prior to December 31, 2014, (a) the sum of (x) 4.25 and (y) an amount (not to exceed 0.50) to reflect new debt used to reduce NCR's unfunded pension liabilities, to (b) 1.00, (ii) in the case of any fiscal quarter ending after December 31, 2014 and on or prior to December 31, 2016, (a) the sum of (x) 4.00 and (y) an amount (not to exceed 0.75) to reflect new debt used to reduce NCR's unfunded pension liabilities, to (b) 1.00, (iii) in the case of any fiscal quarter ending after December 31, 2016 and prior to December 31, 2017, 4.00 to 1.00 and (iv) in the case of any fiscal quarter ending on or after December 31, 2017, 3.75 to 1.00; and
	•	an interest coverage ratio of at least 3.50 to 1.00.
	At September 30, 2013, the maximum consolidated leverage ratio under the Senior Secured Credit Facility was 4.35 to 1.00.
	The Senior Secured Credit Facility also contains events of default, which are customary for similar financings. Upon the occurrence of an event of default, the lenders may, among other things, terminate the loan commitments, accelerate all loans and require cash collateral deposits in respect of outstanding letters of credit.
	The Company may request, at any time and from time to time, but the lenders are not obligated to fund, the establishment of one or more incremental term loans and/or revolving credit facilities (subject to the agreement of existing lenders or additional financial institutions to provide such term loan and/or revolving credit facilities) with commitments in an aggregate amount not to exceed the greater of (i) $150 million, and (ii) such amount as would not (a) prior to the date that the Company obtains an investment grade rating cause the leverage ratio under the Senior Secured Credit Facility, calculated on a pro forma basis including the incremental facility and assuming that it and the revolver are fully drawn, to exceed 2.50 to 1.00, and (b) on and after the date that the Company obtains an investment grade rating cause the leverage ratio under the Senior Secured Credit Facility, calculated on a pro forma basis including the incremental facility and assuming that it and the revolver are fully drawn, to exceed a ratio that is 0.50 less than the leverage ratio then applicable under the financial covenants of the Senior Secured Credit Facility, the proceeds of which can be used for working capital requirements and other general corporate purposes.
	Senior Unsecured Notes On September 17, 2012, the Company issued $600 million aggregate principal amount of 5.00% senior unsecured notes due in 2022 (the 5.00% Notes). The 5.00% Notes were sold at 100% of the principal amount and will mature on July 15, 2022. On December 18, 2012, the Company issued $500 million aggregate principal amount of 4.625% senior unsecured notes due in 2021 (the 4.625% Notes). The 4.625% Notes were sold at 100% of the principal amount and will mature on February 15, 2021. The 5.00% and 4.625% Notes are unsecured senior obligations of the Company and are guaranteed, fully and unconditionally, on a joint and several basis, by our subsidiaries, NCR International, Inc. and Radiant Systems, Inc., which also guarantee our obligations under the Senior Secured Credit Facility.
	We have the option to redeem the 5.00% Notes, in whole or in part, at any time on or after July 15, 2017, at a redemption price of 102.5%, 101.667%, 100.833% and 100% during the 12-month periods commencing on July 15, 2017, 2018, 2019 and 2020 and thereafter, respectively, plus accrued and unpaid interest to the redemption date. Prior to July 15, 2017, we may redeem the 5.00% Notes, in whole or in part, at a redemption price equal to 100% of the principal amount plus a make-whole premium and accrued and unpaid interest to the redemption date. Prior to July 15, 2015, we may redeem the 5.00% Notes in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the notes originally issued at a redemption price of 105% plus accrued and unpaid interest to the redemption date, with the net cash proceeds from one or more qualified equity offerings under certain further requirements.
	We have the option to redeem the 4.625% Notes, in whole or in part, at any time on or after February 15, 2017, at a redemption price of 102.313%, 101.156% and 100% during the 12-month periods commencing on February15, 2017, 2018 and 2019 and thereafter, respectively, plus accrued and unpaid interest to the redemption date. Prior to February 15, 2017, we may redeem the 4.625% Notes, in whole or in part, at a redemption price equal to 100% of the principal amount plus a make-whole premium and accrued and unpaid interest to the redemption date. Prior to February 15, 2016, we may redeem the 4.625% Notes in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the notes originally issued at a redemption price of 104.625% plus accrued and unpaid interest to the redemption date, with the net cash proceeds from one or more qualified equity offerings under certain further requirements.
	The terms of the indentures for these notes, among other things, limit the ability of the Company and certain of its subsidiaries to incur additional debt or issue redeemable preferred stock; pay dividends or make certain other restricted payments or investments; incur liens; sell assets; incur restrictions on the ability of our subsidiaries to pay dividends to us; enter into affliliate transactions; engage in sale and leaseback transactions; and consolidate, merge, sell or otherwise dispose of all or substantially all of our assets. These covenants are subject to significant exceptions and qualifications. For example, if these notes are assigned an investment grade rating by Moody's or S&P and no default has occurred or is continuing, certain covenants will be terminated.
	Additionally, in connection with the 5.00% Notes and the 4.625% Notes, the Company deferred approximately $11 million and $7 million of debt issuance costs, respectively, which are being amortized to interest expense over the life of the debt.
	Fair Value of Debt The fair value of debt is based on a discounted cash flow model that incorporates a market yield curve based on the Company’s credit rating with adjustments for duration. As of September 30, 2013 and December 31, 2012, the fair value of debt was $2.16 billion and $1.97 billion, respectively, and has been measured using significant other observable inputs (Level 2).

	7. INCOME TAXES
	Income tax provisions for interim (quarterly) periods are based on estimated annual income taxes calculated separately from the effect of significant, infrequent or unusual items. Income tax expense was $19 million for the three months ended September 30, 2013 compared to $33 million for the three months ended September 30, 2012. The decrease in income tax expense was driven by tax on a favorable mix of earnings and the release of a $10 million valuation allowance due to the implementation of a tax planning strategy which enabled the Company to access certain deferred tax assets.
	Income tax expense was $44 million for the nine months ended September 30, 2013 compared to $68 million for the nine months ended September 30, 2012. The change in income tax is primarily driven by tax on a favorable mix of earnings, favorable tax legislation, and the release of a valuation allowance offset by a less favorable change in uncertain tax positions. The nine months ended September 30, 2013 included a one-time benefit of approximately $16 million in connection with the American Taxpayer Relief Act of 2012 that was signed into law in January 2013 and the related retroactive tax relief for certain law provisions that expired in 2012. The nine months ended September 30, 2013 also included the release of a $10 million valuation allowance due to the implementation of a tax planning strategy which enabled the Company to access certain deferred tax assets. The nine months ended September 30, 2012 included a $13 million favorable settlement with Japan for the 2001 through 2006 tax years and a $14 million favorable settlement with the Canada Revenue Agency for the 2003 tax year.

During the three and nine months ended September 30, 2013, the Company did not grant any stock options. During the three and nine months ended September 30, 2012, the Company granted stock options and the weighted average fair value of option grants was estimated based on the below weighted average assumptions, which was $8.24 for the nine months ended September 30, 2012.

	Risk-free interest rate	0.64%	0.78%
	Expected volatility	40.60%	40.10%
	Expected holding period (years)	5	5
	Expected volatility incorporates a blend of both historical volatility of the Company’s stock over a period equal to the expected term of the options and implied volatility from traded options on the Company’s stock, as management believes this is more representative of prospective trends. The Company uses historical data to estimate option exercise and employee terminations within the valuation model. The expected holding period represents the period of time that options are expected to be outstanding. The risk-free interest rate for periods within the contractual life of the option is based on the five-year U.S. Treasury yield curve in effect at the time of grant.
	As of September 30, 2013, the total unrecognized compensation cost of $62 million related to unvested restricted stock grants is expected to be recognized over a weighted average period of approximately 1.6 years. As of September 30, 2013, the total unrecognized compensation cost of $1 million related to unvested stock option grants is expected to be recognized over a weighted average period of approximately 0.6 years.

	In the normal course of business, NCR is subject to various proceedings, lawsuits, claims and other matters, including, for example, those that relate to the environment and health and safety, labor and employment, employee benefits, import/export compliance, intellectual property, data privacy and security, product liability, commercial disputes and regulatory compliance, among others. Additionally, NCR is subject to diverse and complex laws and regulations, including those relating to corporate governance, public disclosure and reporting, environmental safety and the discharge of materials into the environment, product safety, import and export compliance, data privacy and security, antitrust and competition, government contracting, anti-corruption, and labor and employment, which are rapidly changing and subject to many possible changes in the future. Compliance with these laws and regulations, including changes in accounting standards, taxation requirements, and federal securities laws among others, may create a substantial burden on, and substantially increase costs to NCR or could have an impact on NCR's future operating results. NCR believes the amounts provided in its Condensed Consolidated Financial Statements, as prescribed by GAAP, are currently adequate in light of the probable and estimable liabilities with respect to such matters, but there can be no assurances that the amounts required to satisfy alleged liabilities from such matters will not impact future operating results. Other than as stated below, the Company does not currently expect to incur material capital expenditures related to such matters. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various lawsuits, claims, legal proceedings and other matters, including but not limited to the Fox River and Kalamazoo River environmental matters and other matters discussed below, and to comply with applicable laws and regulations, will not exceed the amounts reflected in NCR's Condensed Consolidated Financial Statements or will not have a material adverse effect on its consolidated results of operations, capital expenditures, competitive position, financial condition or cash flows. Any costs that may be incurred in excess of those amounts provided as of September 30, 2013 cannot currently be reasonably determined, or are not currently considered probable.
	In 2012, NCR received anonymous allegations from a purported whistleblower regarding certain aspects of the Company's business practices in China, the Middle East and Africa. The principal allegations received in 2012 relate to the Company's compliance with the Foreign Corrupt Practices Act (FCPA) and federal regulations that prohibit U.S. persons from engaging in certain activities in Syria.  NCR promptly retained experienced outside counsel and began an internal investigation of those allegations that was completed in January 2013.  On August 31, 2012, the Board of Directors received a demand letter from an individual shareholder demanding that the Board investigate and take action in connection with certain of the whistleblower allegations. The Board formed a Special Committee to investigate those matters, and that Special Committee also separately retained experienced outside counsel, and completed an investigation in January 2013. On January 23, 2013, upon the recommendation of the Special Committee following its review, the Board of Directors adopted a resolution rejecting the shareholder demand. As part of its resolution, the Board determined, among other things, that the officers and directors named in the demand had not breached their fiduciary duties and that the Company will not commence litigation against the named officers and directors. The Board further resolved to review measures proposed and implemented by management to strengthen the Company's compliance with trade embargos, export control laws and anti-bribery laws. In March 2013, the shareholder who sent the demand filed a derivative action in a Georgia state court, naming as defendants three Company officers, five members of the Board of Directors, and the Company as a nominal defendant. The Company and the officers and directors removed the case to federal court in Georgia. In July 2013, the Board of Directors received a demand letter from another shareholder with respect to allegations similar to those contained in the prior demand letter. In September 2013, the Board of Directors rejected the demand contained in that letter.
	With respect to Syria, in 2012 NCR voluntarily notified the U.S. Treasury Department, Office of Foreign Assets Control (OFAC) of potential violations and ceased operations in Syria, which were commercially insignificant. The notification related to confusion stemming from the Company's failure to register in Syria the transfer of the Company's Syrian branch to a foreign subsidiary and to deregister the Company's legacy Syrian branch, which was a branch of NCR Corporation. The Company received a license from OFAC on January 3, 2013, and subsequent licenses on April 29, 2013 and July 12, 2013, that permit the Company to take measures required to wind down its past operations in Syria. The Company also submitted a detailed report to OFAC regarding this matter, including a description of the Company's comprehensive export control program and related remedial measures.
	With respect to the FCPA, the Company made a presentation in 2012 to the staff of the Securities and Exchange Commission (SEC) and the U.S. Department of Justice (DOJ) providing the facts known to the Company related to the whistleblower's FCPA allegations, and advising the government that many of these allegations were unsubstantiated. The Company is responding to subpoenas of the SEC and requests of the DOJ for documents and information related to the FCPA, including matters related to the whistleblower's FCPA allegations. The Company's investigations of the whistleblower's FCPA allegations identified a few opportunities to strengthen the Company's comprehensive FCPA compliance program, and remediation measures were proposed and are being implemented.
	The Company is fully cooperating with the authorities with respect to all of these matters. There can be no assurance that the Company will not be subject to fines or other remedial measures as a result of OFAC's, the SEC's or the DOJ's investigations.
	In relation to a patent infringement case filed by a company known as Automated Transactions LLC (ATL) the Company agreed to defend and indemnify its customers, 7-Eleven and Cardtronics. On behalf of those customers, the Company won summary judgment in the case in March 2011. ATL's appeal of that ruling was decided in favor of 7-Eleven and Cardtronics in 2012, and its petition for review by the United States Supreme Court was denied in January 2013. (There are further proceedings to occur in the trial court on the indemnified companies' counterclaims against ATL, such that the case is not fully resolved, although ATL's claims of infringement in that case have now been fully adjudicated.) ATL contends that Vcom terminals sold by the Company to 7-Eleven (Cardtronics ultimately purchased the business from 7-Eleven) infringed certain ATL patents that purport to relate to the combination of an ATM with an Internet kiosk, in which a retail transaction can be realized over an Internet connection provided by the kiosk. Independent of the litigation, the U.S. Patent and Trademark Office (USPTO) rejected the parent patent as invalid in view of certain prior art, although related continuation patents were not reexamined by the USPTO. ATL filed a second suit against the same companies with respect to a broader range of ATMs, based on the same patents plus a more recently issued patent; that suit has been consolidated with the first case.
	Environmental Matters NCR's facilities and operations are subject to a wide range of environmental protection laws, and NCR has investigatory and remedial activities underway at a number of facilities that it currently owns or operates, or formerly owned or operated, to comply, or to determine compliance, with such laws. Also, NCR has been identified, either by a government agency or by a private party seeking contribution to site clean-up costs, as a potentially responsible party (PRP) at a number of sites pursuant to various state and federal laws, including the Federal Water Pollution Control Act, the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and comparable state statutes. Other than the Fox River matter and the Kalamazoo River matter detailed below, we currently do not anticipate material expenses and liabilities from these environmental matters.
	Fox River NCR is one of eight entities that were formally notified by governmental and other entities, such as local Native American tribes, that they are PRPs for environmental claims (under CERCLA and other statutes) arising out of the presence of polychlorinated biphenyls (PCBs) in sediments in the lower Fox River and in the Bay of Green Bay in Wisconsin. The other Fox River PRPs that received notices are Appleton Papers Inc. (API; now known as Appvion, Inc.), P.H. Glatfelter Company, Georgia-Pacific Consumer Products LP (GP, successor to Fort James Operating Company), WTM I Co. (formerly Wisconsin Tissue Mills, now owned by Canal Corporation, formerly known as Chesapeake Corporation), CBC Corporation (formerly Riverside Paper Corporation), U.S. Paper Mills Corp. (owned by Sonoco Products Company), and Menasha Corporation. NCR was identified as a PRP because of alleged PCB discharges from two carbonless copy paper manufacturing facilities it previously owned, which were located along the Fox River. NCR sold its facilities in 1978 to API. Some parties contend that NCR is also responsible for PCB discharges from paper mills owned by other companies because NCR carbonless copy paper "broke" was allegedly purchased by those other mills as a raw material.
	The United States Environmental Protection Agency (USEPA) and Wisconsin Department of Natural Resources (together, the Governments) developed clean-up plans for the upper and lower parts of the Fox River and for portions of the Bay of Green Bay. On November 13, 2007, the Governments issued a unilateral administrative order (the 2007 Order) under CERCLA to the eight original PRPs, requiring them to perform remedial work under the Governments’ clean-up plan. In April 2009, NCR and API formed a limited liability company (the LLC), which entered into an agreement with an environmental remediation contractor to perform the work at the Fox River site. In-water dredging and remediation under the clean-up plan commenced shortly thereafter.
	NCR and API, along with B.A.T Industries p.l.c. (BAT), share a portion of the cost of the Fox River clean-up and natural resource damages (NRD) based upon a 1998 agreement (the Cost Sharing Agreement) and a 2005 arbitration award (subsequently confirmed as a judgment). The Cost Sharing Agreement and the arbitration resolved disputes that arose out of agreements relating to the Company's 1978 sale of its Fox River facilities to API. The agreement and award result in a 45% share for NCR of the first $75 million of such costs (a threshold that was reached in 2008), and a 40% share for amounts in excess of $75 million. The non-NCR balance is shared on a joint and several basis by API and BAT.
	Various litigation proceedings concerning the Fox River are pending. In a contribution action filed in 2008 seeking to determine allocable responsibility of several companies and governmental entities, a federal court in Wisconsin ruled that NCR and API did not have a right to obtain contribution from the other parties, but that those parties could obtain contribution from NCR and API with respect to certain moneys they had spent. Decisions in that action were issued in 2009, 2011, 2012 and 2013, with a final judgment entered in 2013. The final judgment held the Company liable in the approximate amount of $76 million; the Company prevailed on claims seeking to hold it liable under an “arranger” theory for the most upriver portion of the site, where claimed damages were approximately $95 million. The Company has secured a bond to stay execution on the judgment and has commenced an appeal from the aspects of the judgment that were not favorable to the Company. Other companies are also appealing from the judgment, including from those aspects that are favorable to the Company.
	In August 2013, GP filed a breach of contract action against the Company in a Wisconsin state court, seeking reimbursement of expenses incurred under Fox River-related agreements entered into by certain PRPs in the 1990s; the Wisconsin federal court had ruled the expenses could not be recovered in the context of the contribution action.  Any liability arising under those agreements would be subject to the cost-sharing obligations described herein pertaining to API, BAT, AT&T and Alcatel-Lucent.
	In 2010, the Governments filed a lawsuit (the Government enforcement action) in Wisconsin federal court against the companies named in the 2007 Order. After a 2012 trial, in May 2013 the court held, among other things, that harm at the site is not divisible, and it entered a declaratory judgment against seven defendants (including NCR), finding them jointly and severally liable to comply with the applicable provisions of the 2007 Order. The court also issued an injunction against four companies (including NCR), ordering them to comply with the applicable provisions of the 2007 Order. Several parties, including NCR, have appealed from the judgment.
	In April 2012, the court ruled in the Government enforcement action that API did not have direct CERCLA liability to the Governments, without disturbing API’s continuing obligation to pay under the Cost Sharing Agreement, arbitration award and judgment. Following the court's decision and API's subsequent and disputed withdrawal from the LLC, API has refused to pay for remediation costs and the Company has funded the full cost of remediation activity ordered by the court. NCR has sought payment from API under the Cost Sharing Agreement, and NCR’s payment demands made upon API as of September 30, 2013 total to approximately $70 million. The Company believes that the court's decision dismissing the Governments' claims against API has no effect on API's independent contractual and judgment-based obligations to NCR. The Company and API are engaged in arbitration proceedings over API’s failure to pay; API has counterclaimed against NCR. In connection with the dispute, in public filings in August 2013 API states that the Wisconsin federal court's rulings “do not affect [API’s] rights or obligations to share defense and liability costs with NCR in accordance with the terms of a 1998 agreement [the Cost Sharing Agreement] and a 2005 arbitration determination . . .” Appleton also reports in the same filing that “[t]he current carrying amount of [API’s] liability under the [a]rbitration is $61.7 million, which represents [API’s] best estimate of amounts to be paid for 2012 and 2013.”
	The extent of NCR's potential Fox River liability remains subject to many uncertainties. NCR's eventual remediation liability, which is expected to be paid out over a period extending through approximately 2017, followed by long-term monitoring, will depend on a number of factors. In general, the most significant factors include: (1) the total clean-up costs, which are estimated at $827 million (there can be no assurances that this estimate will not be significantly higher as work progresses); (2) total NRD for the site, which may range from zero to $246 million (the government in one court filing in 2009 indicated claims could be as high as $382 million; in a September 2011 ruling the Wisconsin federal court ruled that the defendants in the contribution litigation could seek recovery against NCR for overpayments of NRD, although NRD recovery, if any, is a disputed issue that is not expected to be determined before 2014); (3) the share of future clean-up costs and NRD that NCR will bear, which under the current rulings by the federal court is assumed to be the full extent of clean-up activities other than for the most upriver portion of the site; (4) NCR's transaction and litigation costs to defend itself in this matter; and (5)  the share of NCR's payments that API or BAT will bear, which is established by the Cost Sharing Agreement, arbitration award and judgment. With respect to the last point, as a result of certain corporate transactions unrelated to NCR, API is itself indemnified by Windward Prospects Limited, which has funded and managed much of API's liability to date. NCR's analysis of this factor assumes that API and Windward Prospects are financially viable and pay their percentage share. This analysis also assumes that BAT would be financially viable and willing to pay the joint and several obligation if API does not.
	Calculation of the Company's Fox River reserve is subject to several complexities, and it is possible there could be additional changes to some elements of the reserve over upcoming periods, although the Company is unable to predict or estimate such changes at this time. There can be no assurance that the clean-up and related expenditures will not have a material effect on NCR's capital expenditures, earnings, financial condition, cash flows, or competitive position. As of September 30, 2013, the net reserve for the Fox River matter was approximately $101 million, compared to $115 million as of December 31, 2012. The decrease in the reserve is due to payments for clean-up activities and litigation costs. NCR contributes to the LLC in order to fund remediation activities and generally, by contract, funds three months' worth of remediation activities in advance. As of September 30, 2013 and December 31, 2012, approximately $5 million and $3 million, respectively, remained from this funding and was recorded in other current assets in the Condensed Consolidated Balance Sheets. NCR's reserve for the Fox River matter is reduced as the LLC makes payments to the remediation contractor and other vendors with respect to remediation activities.
	Under a 1996 agreement, AT&T and Alcatel-Lucent are responsible severally (not jointly) for indemnifying NCR for certain portions of the amounts paid by NCR for the Fox River matter over a defined threshold and subject to certain offsets. (The agreement governs certain aspects of AT&T Corp.'s divestiture of NCR and of what was then known as Lucent Technologies.) NCR's estimate of what AT&T and Alcatel-Lucent will be obligated to pay under the indemnity totaled approximately $62 million as of September 30, 2013 and $84 million as of December 31, 2012, and is deducted in determining the net reserve discussed above.
	In connection with the Fox River and other matters, through September 30, 2013, NCR has received a combined total of approximately $162 million in settlements reached with its principal insurance carriers. Portions of most of these settlements are payable to a law firm that litigated the claims on the Company's behalf. Some of the settlements cover not only the Fox River but also other environmental sites. Of the total amount collected to date, $9 million is subject to competing claims by API. As of September 30, 2013, NCR had reached settlement with all but one of the insurance companies against which it had advanced claims with respect to the Fox River.
	Kalamazoo River In November 2010, USEPA issued a "general notice letter" to NCR with respect to the Allied Paper, Inc./Portage Creek/Kalamazoo River Superfund Site (Kalamazoo River site) in Michigan. Three other companies - International Paper, Mead Corporation, and Consumers Energy - also received general notice letters at or about the same time. The EPA asserts that the site is contaminated by various substances, primarily PCBs, as a result of discharges by various paper mills located along the river. The EPA does not claim that the Company made direct discharges into the Kalamazoo River, but indicated that "NCR may be liable under Section 107 of CERCLA ... as an arranger, who by contract or agreement, arranged for the disposal, treatment and/or transportation of hazardous substances at the Site." The EPA stated that it "may issue special notice letters to [NCR] and other PRPs for future RI/FS [remedial investigation / feasibility studies] and RD/RA [remedial design / remedial action] negotiations."
	Also in connection with the Kalamazoo River site, in December 2010 the Company was sued in federal court by three companies in a contribution and cost recovery action for alleged pollution. The suit, pending in Michigan, asks that the Company pay a "fair portion" of these companies’ costs, which are represented in the complaint as $79 million to date; various removal and remedial actions remain to be performed at the Kalamazoo River site, the costs for which have not been determined. The suit alleges that the Company is liable as an "arranger" under CERCLA. The case was tried in a Michigan federal court in February 2013; on September 26, 2013 the court issued a decision that held NCR was liable as an “arranger,” at least as of March 1969. PCB-containing carbonless copy paper was produced from approximately 1954 to April 1971.  The Court did not determine NCR’s share of the overall liability or how NCR’s liability relates to the liability of other liable or potentially liable parties at the site. The amount of damages, if any, will be litigated in a subsequent phase of the case. If the Company is found liable for money damages with respect to the Kalamazoo River site, it would have claims against API and BAT under the Cost Sharing Agreement, arbitration award and judgment discussed above in connection with the Fox River matter and against AT&T and Alcatel-Lucent.
	Environmental Remediation Estimates It is difficult to estimate the future financial impact of environmental laws, including potential liabilities. NCR records environmental provisions when it is probable that a liability has been incurred and the amount or range of the liability is reasonably estimable. Provisions for estimated losses from environmental restoration and remediation are, depending on the site, based generally on internal and third-party environmental studies, estimates as to the number and participation level of other PRPs, the extent of contamination, estimated amounts for attorney and other fees, and the nature of required clean-up and restoration actions. Reserves are adjusted as further information develops or circumstances change. Management expects that the amounts reserved from time to time will be paid out over the period of investigation, negotiation, remediation and restoration for the applicable sites. The amounts provided for environmental matters in NCR's Condensed Consolidated Financial Statements are the estimated gross undiscounted amounts of such liabilities, without deductions for insurance, third-party indemnity claims or recoveries from the other PRPs, except as qualified in the following sentences. Except for the sharing agreement with API described above with respect to a particular insurance settlement, in those cases where insurance carriers or third-party indemnitors have agreed to pay any amounts and management believes that collectibility of such amounts is probable, the amounts are recorded in the Condensed Consolidated Financial Statements. For the Fox River site, as described above, assets relating to the AT&T and Alcatel-Lucent indemnity and to the API/BAT joint and several obligation are recorded as payment is supported by contractual agreements, public filings and/or payment history.
	Guarantees and Product Warranties Guarantees associated with NCR’s business activities are reviewed for appropriateness and impact to the Company’s Condensed Consolidated Financial Statements. As of September 30, 2013 and December 31, 2012, NCR had no material obligations related to such guarantees, and therefore its Condensed Consolidated Financial Statements do not have any associated liability balance.
	NCR provides its customers a standard manufacturer’s warranty and records, at the time of the sale, a corresponding estimated liability for potential warranty costs. Estimated future obligations due to warranty claims are based upon historical factors, such as labor rates, average repair time, travel time, number of service calls per machine and cost of replacement parts. When a sale is consummated, the total customer revenue is recognized, provided that all revenue recognition criteria are otherwise satisfied, and the associated warranty liability is recorded using pre-established warranty percentages for the respective product classes.
	From time to time, product design or quality corrections are accomplished through modification programs. When identified, associated costs of labor and parts for such programs are estimated and accrued as part of the warranty reserve.
	The Company recorded the activity related to the warranty reserve for the nine months ended September 30 as follows:
	In millions	2013		2012
	Warranty reserve liability
	Beginning balance as of January 1	$	26	$	23
	Accruals for warranties issued	27		32
	Settlements (in cash or in kind)	-31		-31
	Ending balance as of September 30	$	22	$	24
	In addition, NCR provides its customers with certain indemnification rights. In general, NCR agrees to indemnify the customer if a third party asserts patent or other infringement on the part of its customers for its use of the Company’s products subject to certain conditions that are generally standard within the Company’s industries. On limited occasions the Company will undertake additional indemnification obligations for business reasons. From time to time, NCR also enters into agreements in connection with its acquisition and divestiture activities that include indemnification obligations by the Company. The fair value of these indemnification obligations is not readily determinable due to the conditional nature of the Company’s potential obligations and the specific facts and circumstances involved with each particular agreement. The Company has not recorded a liability in connection with these indemnifications, and no current indemnification instance is material to the Company’s financial position. Historically, payments made by the Company under these types of agreements have not had a material effect on the Company’s condensed consolidated financial condition, results of operations or cash flows.

	11. EARNINGS PER SHARE AND SHARE REPURCHASES
	Basic earnings per share is calculated by dividing net income or loss attributable to NCR by the weighted average number of shares outstanding during the reported period. The calculation of diluted earnings per share is similar to basic earnings per share, except that the weighted average number of shares outstanding includes the dilution from potential shares added from unvested restricted stock awards and stock options. The holders of unvested restricted stock awards do not have nonforfeitable rights to dividends or dividend equivalents and therefore, such unvested awards do not qualify as participating securities.
	The components of basic and diluted earnings per share are as follows:

	For the three and nine months ended September 30, 2013, there were no anti-dilutive options. For the three and nine months ended September 30, 2012, outstanding options to purchase approximately 0.3 million and 1.2 million shares of common stock, respectively, were not included in the diluted share count because the options’ exercise prices were greater than the average market price of the underlying common shares and, therefore, the effect would have been anti-dilutive.
	For the three and nine months ended September 30, 2013 and 2012, the Company did not repurchase any shares of its common stock.

Derivative Instrument Detail [Abstract]	'
Derivatives and Hedging Instruments	'
	12. DERIVATIVES AND HEDGING INSTRUMENTS
	NCR is exposed to risks associated with changes in foreign currency exchange rates and interest rates. NCR utilizes a variety of measures to monitor and manage these risks, including the use of derivative financial instruments. NCR has exposure to approximately 50 functional currencies. Since a substantial portion of our operations and revenues occur outside the United States (U.S.), and in currencies other than the U.S. Dollar, our results can be significantly impacted, both positively and negatively, by changes in foreign currency exchange rates.
	Foreign Currency Exchange Risk
	The accounting guidance for derivatives and hedging requires companies to recognize all derivative instruments as either assets or liabilities at fair value in the Condensed Consolidated Balance Sheets. The Company designates foreign exchange contracts as cash flow hedges of forecasted transactions when they are determined to be highly effective at inception.
	Our risk management strategy includes hedging, on behalf of certain subsidiaries, a portion of our forecasted, non-functional currency denominated cash flows for a period of up to 15 months. As a result, some of the impact of currency fluctuations on non-functional currency denominated transactions (and hence on subsidiary operating income, as stated in the functional currency), is mitigated in the near term. The amount we hedge and the duration of hedge contracts may vary significantly. In the longer term (greater than 15 months), the subsidiaries are still subject to the effect of translating the functional currency results to U.S. Dollars. To manage our exposures and mitigate the impact of currency fluctuations on the operations of our foreign subsidiaries, we hedge our main transactional exposures through the use of foreign exchange forward and option contracts. This is primarily done through the hedging of foreign currency denominated inter-company inventory purchases by NCR’s marketing units and the foreign currency denominated inputs to our manufacturing units. The related foreign exchange contracts are designated as highly effective cash flow hedges. The gains or losses on these hedges are deferred in accumulated other comprehensive income (AOCI) and reclassified to income when the underlying hedged transaction is recorded in earnings. As of September 30, 2013, the balance in AOCI related to foreign exchange derivative transactions was zero. The gains or losses from derivative contracts related to inventory purchases are recorded in cost of products when the inventory is sold to an unrelated third party.
	We also utilize foreign exchange contracts to hedge our exposure of assets and liabilities denominated in non-functional currencies. We recognize the gains and losses on these types of hedges in earnings as exchange rates change. We do not enter into hedges for speculative purposes.
	Interest Rate Risk
	The Company is party to an interest rate swap agreement that fixes the interest rate on a portion of the Company's LIBOR indexed floating rate borrowings under its Senior Secured Credit Facility through August 22, 2016. The notional amount of the interest rate swap at inception was $560 million and amortizes to $341 million over the term. The Company designates the interest rate swap as a cash flow hedge of forecasted quarterly interest payments made on three-month LIBOR indexed borrowings under the Senior Secured Credit Facility. The interest rate swap was determined to be highly effective at inception.
	Our risk management strategy includes hedging a portion of our forecasted interest payments. These transactions are forecasted and the related interest rate swap agreement is designated as a highly effective cash flow hedge. The gains or losses on this hedge are deferred in AOCI and reclassified to income when the underlying hedged transaction is recorded in earnings. As of September 30, 2013, the balance in AOCI related to the interest rate swap agreement was a loss of $6 million, net of tax.

	Concentration of Credit Risk
	NCR is potentially subject to concentrations of credit risk on accounts receivable and financial instruments such as hedging instruments and cash and cash equivalents. Credit risk includes the risk of nonperformance by counterparties. The maximum potential loss may exceed the amount recognized on the Condensed Consolidated Balance Sheets. Exposure to credit risk is managed through credit approvals, credit limits, selecting major international financial institutions (as counterparties to hedging transactions) and monitoring procedures. NCR’s business often involves large transactions with customers, and if one or more of those customers were to default on its obligations under applicable contractual arrangements, the Company could be exposed to potentially significant losses. However, management believes that the reserves for potential losses are adequate. As of September 30, 2013, NCR did not have any major concentration of credit risk related to financial instruments.

	***    Included in Other current assets in the Condensed Consolidated Balance Sheet.
	****    Included in Other current liabilities and Other liabilities in the Condensed Consolidated Balance Sheet.
	Deposits Held in Money Market Funds A portion of the Company’s excess cash is held in money market funds which generate interest income based on prevailing market rates. Money market fund holdings are measured at fair value using quoted market prices and are classified within Level 1 of the valuation hierarchy.
	Available-For-Sale Securities The Company has investments in mutual funds and equity securities that are valued using the market approach with quotations from the NASDAQ stock exchange and two stock exchanges in Japan. As a result, available-for-sale securities are classified within Level 1 of the valuation hierarchy.
	Interest rate swap As a result of our Senior Secured Credit Facility, we are exposed to risk from changes in LIBOR, which may adversely affect our financial condition. To manage our exposure and mitigate the impact of changes in LIBOR on our financial results, we hedge a portion of our forecasted interest payments through the use of an interest rate swap agreement. The interest rate swap is valued using the income approach inclusive of nonperformance and counterparty risk considerations and is classified within Level 2 of the valuation hierarchy.
	Foreign Exchange Contracts As a result of our global operating activities, we are exposed to risks from changes in foreign currency exchange rates, which may adversely affect our financial condition. To manage our exposures and mitigate the impact of currency fluctuations on our financial results, we hedge our primary transactional exposures through the use of foreign exchange forward and option contracts. The foreign exchange contracts are valued using the market approach based on observable market transactions of forward rates and are classified within Level 2 of the valuation hierarchy.
	Assets Measured at Fair Value on a Non-recurring Basis
	Certain assets have been measured at fair value on a nonrecurring basis using significant unobservable inputs (Level 3). NCR reviews the carrying values of investments when events and circumstances warrant and considers all available evidence in evaluating when declines in fair value are other-than-temporary declines. No impairment charges or material non-recurring fair value adjustments were recorded during the three and nine months ended September 30, 2013.
	During the nine months ended September 30, 2012, we measured the fair value of an investment utilizing the income approach based on the use of discounted cash flows. The discounted cash flows are based on unobservable inputs, including assumptions of projected revenues, expenses, earnings, capital spending, as well as a discount rate determined by management’s estimates of risk associated with the investment. As a result, for the nine months ended September 30, 2012, we recorded an other-than-temporary impairment charge of $7 million in other (expense), net in the Condensed Consolidated Statements of Operations based on Level 3 valuations.

Segment Information and Concentrations	'
	14. SEGMENT INFORMATION AND CONCENTRATIONS
	The Company manages and reports its businesses in the following four segments:
	•	Financial Services - We offer solutions to enable customers in the financial services industry to reduce costs, generate new revenue streams and enhance customer loyalty. These solutions include a comprehensive line of ATM and payment processing hardware and software and cash management software, and related installation, maintenance, and managed and professional services. We also offer a complete line of printer consumables.
	•	Retail Solutions - We offer solutions to customers in the retail industry designed to improve selling productivity and checkout processes as well as increase service levels. These solutions primarily include retail-oriented technologies, such as point of sale terminals and related software, bar-code scanners, as well as innovative self-service kiosks, such as self-checkout. We also offer installation, maintenance, managed and professional services and a complete line of printer consumables.
	•	Hospitality - We offer technology solutions to customers in the hospitality industry, serving businesses that range from a single store or restaurant to global chains and sports and entertainment venues.

	These segments represent components of the Company for which separate financial information is available that is utilized on a regular basis by the chief operating decision maker in assessing segment performance and in allocating the Company's resources. Management evaluates the performance of the segments based on revenue and segment operating income. Assets are not allocated to segments, and thus are not included in the assessment of segment performance, and consequently, we do not disclose total assets by reportable segment.
	The accounting policies used to determine the results of the operating segments are the same as those utilized for the consolidated financial statements as a whole. Intersegment sales and transfers are not material.
	In recognition of the volatility of the effects of pension expense on our segment results, and to maintain operating focus on business performance, pension expense, as well as other significant, non-recurring items, are excluded from the segment operating results utilized by our chief operating decision maker in evaluating segment performance and are separately delineated to reconcile back to total reported income from operations.
	The following table presents revenue and operating income by segment:
