Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies References herein to “we,” “us,” “our,” the “Company” and “Conduent” refer to Conduent Incorporated and its consolidated subsidiaries unless the context suggests otherwise. Description of Business We are a global enterprise and leading provider of business process services with expertise in transaction-intensive processing, analytics and automation. We serve as a trusted business partner in both the front office and back office, enabling personalized, seamless interactions on a massive scale that improve end user experience. We create value for our commercial and government clients by applying our expertise, technology and innovation to help them drive customer and constituent satisfaction and loyalty, increase process efficiency and respond rapidly to changing market dynamics. Our portfolio includes industry-focused service offerings in attractive growth markets such as healthcare and transportation, as well as multi-industry service offerings such as transaction processing, customer care and payment services. Basis of Presentation Our Consolidated Financial Statements included the historical basis of assets, liabilities, revenues and expenses of the individual businesses of the Company, including joint ventures and partnerships over which the Company has a controlling financial interest. We have prepared the Consolidated Financial Statements pursuant to the rules and regulations of the SEC. Certain reclassifications have been made to prior years to conform to the current year presentation. All intercompany transactions and balances have been eliminated. We have also considered the impact of subsequent events on these consolidated financial statements. Separation from Xerox Corporation On December 31, 2016, Conduent spun-off from Xerox Corporation (Xerox), pursuant to the Separation and Distribution Agreement (Separation). The Separation was completed by way of a pro rata distribution of Conduent shares held by Xerox to Xerox’s shareholders. As a result, we operate as an independent, publicly traded company on the New York Stock Exchange, under the ticker "CNDT". Prior to December 31, 2016, the Financial Statements of the Company were derived from the financial statements and accounting records of Xerox as if the Conduent operated on a standalone basis. Historically, the Company consisted of the Business Process Outsourcing Operating segment within Xerox’s reportable Services segment and did not operate as a separate, standalone company. Accordingly, Xerox performed certain corporate overhead functions for the Company. Therefore, certain corporate costs, including compensation costs for corporate employees supporting the Company, were allocated from Xerox. It is not practicable to estimate actual costs that would have been incurred had the Company been a separate standalone company during the periods presented. Allocations for management costs and corporate support services provided to the Company totaled $165 million and $170 million for years ended December 31, 2016 and December 31, 2015, respectively. Management of the Company believes the assumptions regarding the allocated expenses reasonably reflect the utilization of services provided to or the benefit received by the Company during the periods prior to the Separation. The Consolidated Financial Statements for the periods prior to the Separation do not necessarily include all the expenses that would have been incurred or held by the Company had it been a separate, standalone company. Use of Estimates We prepared the Consolidated Financial Statements using financial information available at the time of preparation, which requires us to make estimates and assumptions that affect the amounts reported. Our most significant estimates pertain to the recognition of revenue for contracts based on the percentage of completion method of accounting, intangible and long-lived assets, valuation of goodwill, contingencies and litigation, income taxes and corporate allocations (for years ended December 31, 2016 and 2015). Our estimates are based on management's best knowledge of current events, historical experience, and on various other assumptions that are believed to be reasonable under the circumstances. As a result, actual results may be different from these estimates. New Accounting Standards Revenue Recognition: In May 2014, the Financial Accounting Standards Board (FASB) updated the accounting guidance related to revenue recognition to clarify the principles for recognizing revenue and replaced all existing revenue recognition guidance in U.S. GAAP with one accounting model. The core principle of the guidance is that an entity should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated guidance also requires additional qualitative and quantitative disclosures relating to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers largely on a disaggregated basis. We have evaluated the adoption impact of the updated accounting guidance on our consolidated financial statements and continue to evaluate the impact on disclosures and internal controls. The new guidance will impact: (1) revenue associated with postage, which will be recognized on a net basis versus the current gross treatment; (2) the timing of revenue recognition associated with fixed fees for certain contracts with more than one performance obligation; and (3) the timing of recognition of certain pricing discounts. We adopted this updated accounting guidance beginning January 1, 2018 using the modified retrospective method under which we will recognize a cumulative-effect adjustment of approximately $20 million at the date of adoption (the expected impact to 2018 revenues is approximately $15 million ), which excludes changes to our revenue associated with the reimbursement of postage. In addition, we recognized approximately $150 million of postage revenue in 2017 that will be recognized on a net basis (for all future periods) in Cost of services. Leases: In February 2016, the FASB updated the accounting guidance related to leases requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases except short term leases (lease term of 12 months or less). The accounting for lessors is largely unchanged. This updated guidance is effective for us beginning January 1, 2019. This guidance must be adopted using a modified retrospective approach through a cumulative-effect adjustment for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. While we are currently evaluating the impact of the updated accounting guidance on our consolidated financial statements; we do expect a material impact to the Company's Consolidated Balance Sheets. Cash Flows: In November 2016 the FASB issued updated accounting guidance regarding the presentation of restricted cash in the statement of cash flows. Specifically, this update requires that restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. At December 31, 2017 and 2016 , we had $9 million and $22 million of restricted cash, respectively, reported in other current assets. This update is effective for us beginning January 1, 2018. Business Combinations: In January 2017, the FASB issued clarifying accounting guidance related to the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This update is effective for us beginning January 1, 2018, with early adoption permitted. The amendment in this update will be applied prospectively. There will be no material impact from the adoption of this clarifying accounting guidance on our consolidated financial statements. Recently Adopted Accounting Standards Goodwill: In January 2017, the FASB issued updated accounting guidance for simplifying the goodwill impairment test. Under the new guidance, an entity does not have to calculate the implied fair value of goodwill at the impairment testing date of its assets and liabilities as if those assets and liabilities had been acquired in a business combination. Instead the goodwill impairment test will compare the fair value of a reporting unit with its carrying amount and recognize as an impairment charge any amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit. We have elected to early adopt this new guidance for our goodwill impairment tests performed after January 1, 2017. Adoption did not have any effect on our financial condition, results of operations or cash flows. Summary of Accounting Policies Revenue Recognition We primarily generate revenue through services. Revenue is recognized when it is realized or realizable and earned. We consider revenue realized or realizable and earned when we have persuasive evidence of an arrangement, delivery has occurred, the transaction price is fixed or determinable and collectibility is reasonably assured. Delivery does not occur until services have been provided to the customer, risk of loss has transferred to the customer, and either customer acceptance has been obtained, customer acceptance provisions have lapsed or the company has objective evidence that the criteria specified in the customer acceptance provisions have been satisfied. The transaction price is not considered to be fixed or determinable until all contingencies related to the sale have been resolved. Outsourcing Services: Revenues associated with outsourcing services are generally recognized as services are rendered, which is generally on the basis of the number of accounts or transactions processed. In service arrangements where final acceptance of a system or solution by the customer is required, revenue is deferred until all acceptance criteria have been met. Revenues on cost reimbursable contracts are recognized by applying an estimated factor to costs as incurred, determined by the contract provisions and prior experience. Revenues on unit-price contracts are recognized at the contractual selling prices as work is completed and accepted by the customer. Revenues on time and material contracts are recognized at the contractual rates as the labor hours and direct expenses are incurred. Revenues on certain fixed price contracts where we provide system development and implementation services are recognized over the contract term based on the percentage of development and implementation services that are provided during the period compared with the total estimated development and implementation services to be provided over the entire contract using the percentage-of-completion accounting methodology. These services require that we perform significant, extensive and complex design, development, modification or implementation of our customers' systems. Performance will often extend over long periods, and our right to receive future payment depends on our future performance in accordance with the agreement. The percentage-of-completion methodology involves recognizing probable and reasonably estimable revenue using the percentage of services completed, on a current cumulative cost to an estimated total cost basis, using a reasonably consistent profit margin over the period. Revenues earned in excess of related billings are accrued, whereas billings in excess of revenues earned are deferred until the related services are provided. We recognize revenues for non-refundable, upfront implementation fees on a straight-line basis over the period between the initiation of the services through the end of the contract term. In connection with our services arrangements, we incur and capitalize costs to originate these long-term contracts and to perform the migration, transition and setup activities necessary to enable us to perform under the terms of the arrangement. Certain initial direct costs of an arrangement are capitalized and amortized over the contractual service period of the arrangement to cost of services. From time to time, we also provide inducements to customers in various forms, including contractual credits, which are capitalized and amortized as a reduction of revenue over the term of the contract. Spending associated with customer-related deferred set-up/transition and inducement costs were as follows: Year Ended December 31, (in millions) 2017 2016 2015 Set-up/transition and inducement expenditures $ 55 $ 63 $ 65 The capitalized amount of customer contract costs were as follows: Year Ended December 31, (in millions) 2017 2016 Capitalized customer contract costs (1) 126 137 __________ (1) The balance at December 31, 2017 and 2016 are expected to be amortized over a weighted average period of approximately nine and eight years, respectively. Amortization expense for the next five years and thereafter is expected to be as follows (in millions): 2018 2019 2020 2021 2022 Thereafter $ 54 $ 22 $ 13 $ 9 $ 6 $ 22 Long-lived assets used in the fulfillment of the arrangements are capitalized and depreciated over the shorter of their useful life or the term of the contract if an asset is contract specific. Multiple Element Arrangements: As described above, we enter into the following revenue arrangements that may consist of multiple deliverables including contracts for multiple types of outsourcing services, as well as professional and value-added services. For instance, we may contract for an implementation or development project and also provide services to operate the system which we implement or develop over a period of time; or we may contract to scan, manage and store customer documents. In substantially all of our multiple element arrangements, we are able to separate the deliverables since we normally will meet both of the following criteria: • The delivered item(s) has value to the customer on a stand-alone basis; and • If the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in our control. Consideration in a multiple-element arrangement is allocated at the inception of the arrangement to all deliverables on the basis of the relative selling price. When applying the relative selling price method, the selling price for each deliverable is primarily determined based on vendor-specific objective evidence (VSOE), third-party evidence (TPE), or our best estimate of the selling price. The above noted revenue policies are then applied to each separated deliverable, as applicable. Revenue Reporting: Revenue from sales of third-party vendor products or services is recorded net of costs when the Company is acting as an agent between the customer and the vendor or supplier, or gross when the Company is a principal to the transaction. Postage is generally recognized on a gross basis. Several factors are considered to determine whether the company is an agent or principal, most notably whether the Company is the primary obligor to the customer, or has inventory risk. Consideration is also given to whether the Company adds meaningful value to the vendor’s product or service, was involved in the selection of the vendor’s product or service, has latitude in establishing the sales price or has credit risk. Revenue-based Taxes: We report revenue net of any revenue-based taxes assessed by governmental authorities that are imposed on and concurrent with specific revenue-producing transactions. The primary revenue-based taxes are sales tax and value-added tax (VAT). Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand, including money market funds and investments with original maturities of three months or less. Receivable Sales We had transferred certain portions of our receivable portfolios in 2016 and 2015 and accounted for those transfers as sales based on meeting the criteria for derecognition. Losses on the sale of receivables depend, in part, on both (a) the cash proceeds and (b) the net non-cash proceeds received or paid. When we have sold receivables, we normally received beneficial interests in the transferred receivables from the purchasers as part of the proceeds. Refer to Note 4 – Accounts Receivable, Net for more details on our receivable sales . Assets/Liabilities Held for Sale We classify assets as held for sale in the period when the following conditions are met: (i) management, having the authority to approve the action, commits to a plan to sell the asset (disposal group); (ii) the asset (disposal group) is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets (disposal group); (iii) an active program to locate a buyer and other actions required to complete the plan to sell the asset (disposal group) have been initiated; (iv) the sale of the asset (disposal group) is probable, and transfer of the asset (disposal group) is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond our control extend the period of time required to sell the asset (disposal group) beyond one year; (v) the asset (disposal group) is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (vi) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. A long-lived asset (disposal group) that is classified as held for sale is initially measured at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset (disposal group) until the date of sale. The fair value of a long-lived asset (disposal group) less any costs to sell is assessed each reporting period it remains classified as held for sale and any subsequent changes are reported as an adjustment to the carrying value of the asset (disposal group), as long as the new carrying value does not exceed the carrying value of the asset at the time it was initially classified as held for sale. In the fourth quarter of 2017, Management approved for disposal through sale of certain assets and businesses. This action was taken as a result of our strategic evaluation of these businesses. As of December 31, 2017, these businesses qualified as assets held for sale. During the year ended December 31, 2017, we reclassified $757 million to assets held for sale and $169 million to liabilities held for sale, as we have an active program to locate buyers for these businesses and we expect these businesses to be sold within one year. Refer to Note 3 – Assets/Liabilities Held for Sale for further discussion. Land, Buildings and Equipment Land, buildings and equipment are recorded at cost. Buildings and equipment are depreciated over their estimated useful lives. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life. Significant improvements are capitalized and maintenance and repairs are expensed when incurred. Refer to Note 5 – Land, Buildings, Equipment and Software, Net for further discussion. Software - Internal Use and Product Internal Use: We capitalize direct costs associated with developing, purchasing or otherwise acquiring software for internal use and amortize these costs on a straight-line basis over the expected useful life of the software, beginning when the software is implemented (Internal Use Software). Costs incurred for upgrades and enhancements that will not result in additional functionality are expensed as incurred. Amounts expended for Internal Use Software are included in Cash Flows from Investing. Product: We also capitalize certain costs related to the development of software solutions to be sold to our customers upon reaching technological feasibility (Product Software). These costs are amortized on a straight-line basis over the estimated economic life of the software. Amounts expended for Product Software are included in Cash Flows from Operations. We perform periodic reviews to ensure that unamortized Product Software costs remain recoverable from estimated future operating profits (net realizable value or NRV). Costs to support or service licensed software are charged to Costs of outsourcing as incurred. Refer to Note 5 – Land, Buildings, Equipment and Software, Net for further information. Goodwill For acquired businesses, the Company records the acquired assets and assumed liabilities based on their relative fair values at the date of acquisitions (commonly referred to as the purchase price allocation). Goodwill represents the excess of the purchase price paid in excess of the fair value of net tangible and intangible assets acquired. For the Company’s business acquisitions, the purchase price is allocated to identifiable intangible assets separate from goodwill if they are from contractual or other legal rights, or if they could be separated from the acquired business and sold, transferred, licensed, rented or exchanged. We test goodwill for impairment annually or more frequent if an event or change in circumstances indicate the asset may be impaired. Impairment testing for goodwill is done at the reporting unit level. We determined the fair value of our reporting units utilizing a combination of both an Income Approach and a Market Approach. The Income Approach utilizes a discounted cash flow analysis based upon the forecasted future business results of our reporting units. The Market Approach utilizes the guideline public company method. If the fair value of a reporting unit is less than its carrying amount, an impairment charge would be recognized for amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit. Refer to Note 6 – Goodwill and Intangible Assets, Net for further information. Other Intangible Assets Other intangible assets primarily consist of assets acquired through business combinations, including installed customer base and distribution network relationships, patents and trademarks. Other intangible assets are amortized on a straight-line basis over their estimated economic lives unless impairment is identified. Refer to Note 6 – Goodwill and Intangible Assets, Net for further information. Impairment of Long-Lived Assets We review the recoverability of our long-lived assets, including buildings, equipment, internal use software, product software and other intangible assets, when events or changes in circumstances occur that indicate that the carrying value of the asset may not be recoverable. The assessment of possible impairment is based on our ability to recover the carrying value of the asset from the expected future pre-tax cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset, an impairment loss is recognized for the difference between estimated fair value and carrying value. Our primary measure of fair value is based on forecasted cash flows. Pension Obligations We sponsor various forms of defined benefit pension plans in several countries covering employees who meet eligibility requirements. Several statistical and other factors that attempt to anticipate future events are used in calculating the expense, liability and asset values related to our pension plans. These factors include assumptions we make about the discount rate, expected return on plan assets, the rate of future compensation increases and mortality rates. The discount rate is used to present value our future anticipated benefit obligations. The discount rate reflects the current rate at which benefit liabilities could be effectively settled considering the timing of expected payments for plan participants. In estimating our discount rate, we consider rates of return on high-quality fixed-income investments adjusted to eliminate the effects of call provisions, as well as the expected timing of pension and other benefit payments. The expected rate of return on plan assets is the long-term rate of return we expect to earn on plan assets. When estimating the expected rate of return, in addition to assessing recent performance, we consider the historical returns earned on plan assets, the rates of return expected in the future, and our investment strategy and asset mix with respect to the plans’ funds. The expected rate of return on plan assets is reviewed annually and revised, as necessary, to reflect changes in financial markets and our investment strategy. Each year, the difference between the actual return on plan assets and the expected return on plan assets, as well as increases or decreases in the benefit obligation as a result of changes in the discount rate and other actuarial assumptions, are added to or subtracted from any cumulative actuarial gain or loss from prior years. This amount is the net actuarial gain or loss recognized in Accumulated other comprehensive loss. We amortize net actuarial gains and losses as a component of net pension cost for a year if, as of the beginning of the year, that net gain or loss (excluding asset gains or losses that have not been recognized in market-related value) exceeds 10% of the greater of the projected benefit obligation or the market-related value of plan assets (the "corridor" method). This determination is made on a plan-by-plan basis. If amortization is required for a particular plan, we amortize the applicable net gain or loss in excess of the 10% threshold on a straight-line basis in net periodic pension cost over the remaining service period of the employees participating in that pension plan. In plans where substantially all participants are inactive, the amortization period for the excess is the average remaining life expectancy of the plan participants. All changes are ultimately recognized as components of net periodic benefit cost, except to the extent they may be offset by subsequent changes. At any point, changes that have been identified and quantified but not recognized as components of net periodic benefit cost, are recognized in Accumulated other comprehensive loss, net of tax. Refer to Note 11 – Employee Benefit Plans for further information regarding our Pension Benefit Obligations . Income Taxes We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are based on differences between U.S. GAAP reporting and tax bases of assets or liabilities and based on current tax laws, regulations and rates. The recognition of deferred tax assets requires an assessment to determine the realization of such assets. Management establishes valuation allowances on deferred tax assets when it is determined “more-likely-than-not” that some portion or all of the deferred tax assets may not be realized. Management considers positive and negative evidence in evaluating the ability of the Company to realize its deferred tax assets, including its historical results and forecasts of future ability to realize its deferred tax assets, including projected future taxable income, the expected timing of the reversals of existing temporary differences and tax planning strategies. We are subject to ongoing tax examinations and assessments in various jurisdictions. We have unrecognized tax benefits for uncertain tax positions. We follow U.S. GAAP which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Our ongoing assessments of the more-likely-than-not outcomes of the examinations and related tax positions require judgment and can materially increase or decrease our effective tax rate, as well as impact our operating results. Refer to Note 12 – Income Taxes for further discussion. Foreign Currency Translation and Re-measurement The functional currency for most foreign operations is the local currency. Net assets are translated at current rates of exchange and income, expense and cash flow items are translated at average exchange rates for the applicable period. The translation adjustments are recorded in Accumulated other comprehensive loss. The U.S. Dollar is used as the functional currency for certain foreign subsidiaries that conduct their business in U.S. Dollars. A combination of current and historical exchange rates is used in re-measuring the local currency transactions of these subsidiaries and the resulting exchange adjustments are recorded in Currency (gains) and losses within other expenses, net together with other foreign currency re-measurements.

In February 2016, we reached an agreement with Atos on the final adjustments to the closing balance of net assets sold as well as the settlement of certain indemnifications and recorded an additional pre-tax loss on the disposal in 2015 of $ 24 million ($ 14 million after-tax). The additional loss was recorded in 2015 as the financial statements had not yet been issued when the agreement was reached with Atos. We made a payment in 2016 to Atos of approximately $ 52 million , representing a $ 28 million adjustment to the final sales price as a result of this agreement and a payment of $ 24 million due from closing. The payment is reflected in Investing cash flows as an adjustment of the sales proceeds.

Certain leases were accounted for as capital leases and the remaining net book value of those assets, included in Land, Buildings and Equipment, net were approximately $32 million and $42 million at December 31, 2017 and 2016 , respectively. Future minimum operating lease commitments that have initial or remaining non-cancelable lease terms in excess of one year at December 31, 2017 were as follows (in millions): 2018 2019 2020 2021 2022 Thereafter $ 163 $ 119 $ 80 $ 53 $ 31 $ 52 Internal Use and Product Software Additions to Internal Use and Product Software as well as year-end balances for these assets were as follows: (in millions) Year Ended December 31, Additions to: 2017 2016 2015 Internal use software $ 36 $ 39 $ 27 Product software 10 10 19 (in millions) December 31, Capitalized Costs, Net 2017 2016 Internal use software $ 106 $ 115 Product software 22 38 Useful lives of our internal use and product software generally vary from one to seven years. Included within product software at December 31, 2017 and 2016 were $2 million and $3 million , respectively, of capitalized costs associated with software system platforms developed for use in certain of our government services businesses. During 2016 we determined that it was probable that we would not fully complete our NY MMIS project in its current form. As a result of this decision an impairment charge of approximately $28 million was recorded in Cost of services. We also recorded an additional impairment charge in 2016 related to the 2015 HE charge of approximately $9 million in Restructuring and asset impairment. In 2015 we decided to discontinue certain future implementations of these software system platforms, and recorded an impairment charge of $160 million ( $14 million in Cost of services and $146 million in Restructuring and asset impairments).

Goodwill and Intangible Assets, Net	Goodwill and Intangible Assets, Net Goodwill The following table presents the changes in the carrying amount of goodwill, by reportable segment: (in millions) Commercial Industries Public Sector Total Balance at December 31, 2015 $ 2,467 $ 2,405 $ 4,872 Foreign currency translation (24 ) (20 ) (44 ) Acquisitions (2 ) — (2 ) Disposition (2 ) — (2 ) Impairment (935 ) — (935 ) Balance at December 31, 2016 $ 1,504 $ 2,385 $ 3,889 Foreign currency translation 19 28 47 Dispositions (19 ) (14 ) (33 ) Assets held for sale (105 ) (432 ) (537 ) Balance at December 31, 2017 $ 1,399 $ 1,967 $ 3,366 Impairment Charge There was no impairment identified for the years ended December 31, 2017 and 2015. In 2016, due to the declining trends and projections in the Commercial Industries reporting unit, we concluded that the fair value of our Commercial Industries reporting unit was less than its carrying value. Accordingly, we recorded a pre-tax goodwill impairment charge of $935 million during the fourth quarter of 2016, which is separately presented in the Consolidated Statements of Income (Loss). There was no impairment identified for the Public Sector in 2016. Based on our quantitative assessments, we concluded that the fair value of our Commercial Industries and Public Sector reporting units exceeded their respective carrying values by 72% and 13% , respectively, at December 31, 2017. The most significant assumptions used in the goodwill analysis relate to a 3% long-term organic growth rate for both the Commercial Industries and Public Sector segments as well as a 9.25% and a 8.75% discount rate for the Commercial Industries and Public Sector segments, respectively. Intangible Assets, Net Net intangible assets were $891 million at December 31, 2017 of which $492 million and $399 million relate to our Commercial Industries and Public Sector segments, respectively.

Restructuring and Related Activities [Abstract]
Restructuring and Asset Impairment Charges	Restructuring Programs and Asset Impairment Charges We engage in a series of restructuring programs related to downsizing our employee base, exiting certain activities, outsourcing certain internal functions and engaging in other actions designed to reduce our cost structure and improve productivity. Prior to 2017, these initiatives primarily consist of severance actions that impacted all major geographies and segments. In 2017, the implementation of our strategic transformation program as well as various productivity initiatives reduced our real estate footprint across all geographies and segments resulting in increased lease cancellation and other related costs. Management continues to evaluate our business, therefore, in future years, there may be additional provisions for new plan initiatives as well as changes in previously recorded estimates as payments are made or actions are completed. Asset impairment charges were also incurred in connection with these restructuring actions for those assets sold, abandoned or made obsolete as a result of these programs. Costs associated with restructuring, including employee severance and lease termination costs are generally recognized when it has been determined that a liability has been incurred, which is generally upon communication to the affected employees or exit from the leased facility. In those geographies where we have either a formal severance plan or a history of consistently providing severance benefits representing a substantive plan, we recognize employee severance costs when they are both probable and reasonably estimable. A summary of our restructuring program activity during the two years ended December 31, 2017 is as follows: (in millions) Severance and Related Costs Lease Cancellation and Other Costs Asset Impairments Total Balance at December 31, 2015 4 — — 4 Restructuring provision 67 7 12 86 Reversals of prior accruals (13 ) — — (13 ) Total Net Current Period Charges 54 7 12 73 Charges against reserve and currency (43 ) (2 ) (11 ) (56 ) Balance at December 31, 2016 15 5 1 21 Restructuring provision 49 49 5 103 Reversals of prior accruals (8 ) (3 ) — (11 ) Total Net Current Period Charges 41 46 5 92 Charges against reserve and currency (42 ) (17 ) (6 ) (65 ) Liabilities held for sale — (4 ) — (4 ) Balance at December 31, 2017 $ 14 $ 30 $ — $ 44 We also recorded costs related to professional support services associated with the implementation of the strategic transformation program of $9 million and $28 million during the years ended December 31, 2017 and 2016 , respectively.

Credit Facility On December 7, 2016 , we entered into a senior secured credit agreement (Credit Agreement) among the Company, its subsidiaries: Conduent Business Services, LLC (CBS), Affiliated Computer Services International B.V. and Conduent Finance, Inc. (CFI), the lenders party and JP Morgan Chase Bank, N.A., as the administrative agent. The Credit Agreement contains senior secured credit facilities (Senior Credit Facilities) consisting of: (i) Senior Secured Term Loan A (Term Loan A) due 2021 with an aggregate principal amount of $700 million ; (ii) Senior Secured Term Loan B (Term Loan B) due 2023 with an aggregate principal amount of $850 million ; (iii) Senior Revolving Credit Facility (Revolving Credit Facility) due 2021 with an aggregate available amount of $750 million including a sub-limit for up to $300 million available for the issuance of letters of credit. Borrowings under the Term Loan A Facility and the Revolving Credit Facility bears interest at a rate equal to either the sum of a base rate plus a margin ranging from 1.00% and 1.50% or the sum of a Eurocurrency rate plus an applicable rate ranging from 2.00% to 2.50% , with either such margin varying according to the total net leverage ratio of CBS. Borrowing under Term Loan B Facility bears interest at a rate equal to the sum of a base rate plus 2.0% , or the sum of a Eurocurrency rate plus 3.0% . CBS is required to pay a quarterly commitment fee under the Revolving Credit Facility at a rate ranging from 0.35% to 0.40% per annum, with such rate varying according to the total net leverage ratio of CBS and the actual daily unused portion of the commitments during the applicable quarter. CBS is also required to pay a fee equal to the adjusted LIBOR on the aggregate face amount of outstanding letters of credit under the Revolving Credit Facility. The Credit Agreement permits us to incur incremental term loan borrowings and /or increase commitments under the Revolving Credit Facility, subject to certain limitations and satisfaction of certain conditions, in an aggregate amount not to exceed (i) $200 million plus, (ii) if the senior secured net leverage ratio of CBS and its subsidiaries does not exceed 2.25 to 1.00 on a pro forma basis (without giving effect to any incurrence under clause (i) that is incurred substantially simultaneously with amounts incurred under clause (ii)), an unlimited amount. All obligations under the Senior Credit Facilities are unconditionally guaranteed by the Company, CBS, CFI and the existing and future direct and indirect wholly owned domestic subsidiaries of CBS (subject to certain exceptions). All obligations under the Senior Credit Facilities, and the guarantees of those obligations, are secured, subject to certain exceptions, by substantially all of the assets of CBS and the guarantors under the Senior Credit Facilities (other than the Company and CFI), including a first-priority pledge of all the capital stock of CBS and the subsidiaries of CBS directly held by CBS or the guarantors (other than the Company and CFI) under the Senior Credit Facilities (which pledge, in the case of any foreign subsidiary, will be limited to 65% of the capital stock of any first-tier foreign subsidiary).

CBS is required to maintain a total net leverage ratio not to exceed 4.25 to 1.00 (a quarterly test) for each quarter through September 30, 2018 and 3.75 to 1.00 for each quarter thereafter. The net proceeds of the borrowings under the Term Loan A of $700 million (approximately $278 million borrowed in Euros) and Term Loan B of $850 million , were used to purchase our international subsidiaries from Xerox Corporation, to pay a distribution to Xerox Corporation and for working capital and other general corporate purposes. At December 31, 2017 we had $1,574 million in outstanding borrowings under our Credit Agreement and had utilized $12 million of our Revolving Credit Facility capacity to issue letters of credit. Discounts and debt issuance costs of $47 million were deferred. Senior Notes On December 7, 2016 , CBS and CFI, each a wholly owned subsidiary of the Company, issued $510 million Senior Unsecured Notes due 2024 bearing interest at 10.5% (the "Senior Notes"). Interest is payable semi-annually, beginning on June 15, 2017. Discounts and debt issuance costs of $17 million were deferred. At the option of the Issuers, the Senior Notes are redeemable in whole or in part, at any time prior to December 15, 2020, at a price equal to 100% of the aggregate principal amount of the Senior Notes plus accrued and unpaid interest, if any, to, but excluding, the redemption date plus a “make-whole” premium.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	Financial Instruments We are exposed to market risk from changes in foreign currency exchange rates and interest rates, which could affect operating results, financial position and cash flows. We manage our exposure to these market risks through our regular operating and financing activities and, when appropriate, through the use of derivative financial instruments. These derivative financial instruments are utilized to hedge economic exposures, as well as to reduce earnings and cash flow volatility resulting from shifts in market rates. We enter into limited types of derivative contracts to manage foreign currency exposures that we hedge. Our primary foreign currency market exposures include the Philippine Peso, Indian Rupee and Mexican Peso. The fair market values of all our derivative contracts change with fluctuations in interest rates or currency exchange rates and are designed so that any changes in their values are offset by changes in the values of the underlying exposures. Derivative financial instruments are held solely as risk management tools and not for trading or speculative purposes. The related cash flow impacts of all of our derivative activities are reflected as cash flows from operating activities. We do not believe there is significant risk of loss in the event of non-performance by the counterparty associated with our derivative instruments because these transactions are executed with a major financial institution. Further, our policy is to deal only with counterparties having a minimum investment grade or better credit rating. Credit risk is managed through the continuous monitoring of exposures to such counterparties. Summary of Foreign Exchange Hedging Positions At December 31, 2017 , we had outstanding forward exchange with gross notional values of $160 million , which is typical of the amounts that are normally outstanding at any point during the year. The impact of our hedging program is not material to our balance sheet or income statement. Approximately 68% of these contracts mature within three months, 12% in three to six months, 15% in six to twelve months and 5% in greater than 12 months. The following is a summary of the primary hedging positions and corresponding fair values as of December 31, 2017 : (in millions) Gross Notional Value Fair Value Asset (Liability) (1) Currencies Hedged (Buy/Sell) Philippine Peso/U.S. Dollar $ 62 $ — Indian Rupee/U.S. Dollar 68 1 Mexican Peso/U.S. Dollar 9 — All Other 21 — Total Foreign Exchange Hedging $ 160 $ 1 ____________ (1) Represents the net receivable (payable) amount included in the Consolidated Balance Sheet at December 31, 2017 .

Fair Value Disclosures [Abstract]
Fair Value of Financial Assets and Liabilities	Fair Value of Financial Assets and Liabilities Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. US. GAAP establishes a framework for measuring that includes a hierarchy used to classify the inputs used in measuring fair value. The levels of the fair value hierarchy are as follows: Level 1: Fair value is determined using an unadjusted quoted price in an active market for identical assets or liabilities. As at December 31, 2017 and 2016, the Company did not have any asset or liability that was measured using Level 1 inputs. Level 2: Fair value is estimated using inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly. All the Company's assets and liabilities that were measured at fair value on a recurring basis as at December 31, 2017 and 2016, were valued using Level 2 inputs. Level 3: Fair value is estimated using unobservable inputs that are significant to the fair value of the assets. As at December 31, 2017 and 2016, the Company did not have any asset or liability that was measured using Level 3 inputs. The following table represents assets and liabilities fair value measured on a recurring basis. The basis for the measurement at fair value in all cases is Level 2 – Significant Other Observable Inputs. As of December 31, (in millions) 2017 2016 Assets: Foreign exchange contracts - forwards $ 2 $ 1 Deferred compensation investments in cash surrender life insurance (1) — 99 Deferred compensation investments in mutual funds (1) — 10 Total $ 2 $ 110 Liabilities: Foreign exchange contracts - forwards $ 1 $ 3 Deferred compensation plan liabilities (1) 99 113 Total $ 100 $ 116 (1) In September 2017, the Company terminated the legacy deferred compensation plans (Plans) and the Company Owned Life Insurance (COLI), which held the Plans’ investments. The Company will make payments to Plan participants of approximately $100 million in the fourth quarter 2018. Fair value for our deferred compensation plan investments in company-owned life insurance is reflected at cash surrender value. Fair value for our deferred compensation plan investments in mutual funds is based on quoted market prices for actively traded investments similar to those held by the plan. Fair value for deferred compensation plan liabilities is based on the fair value of investments corresponding to employees’ investment selections, based on quoted prices for similar assets in actively traded markets. Summary of Other Financial Assets and Liabilities Fair Value Measured on a Nonrecurring Basis The estimated fair values of our other financial assets and liabilities fair value measured on a nonrecurring basis were as follows: December 31, 2017 December 31, 2016 (in millions) Carrying Amount Fair Value Carrying Amount Fair Value Cash and cash equivalents $ 658 $ 658 $ 390 $ 390 Restricted cash 9 9 22 22 Accounts receivable, net 1,104 1,104 1,286 1,286 Short-term debt 82 82 28 28 Long-term debt 1,979 2,070 1,913 1,933 The fair value amounts for Cash and cash equivalents, Restricted cash and Accounts receivable, net, approximate carrying amounts due to the short maturities of these instruments. The fair value of Short and Long-term debt was estimated based on the current rates offered to us for debt of similar maturities (Level 2). The difference between the fair value and the carrying value represents the theoretical net premium or discount we would pay or receive to retire all debt at such date. The fair value of the Goodwill impairment charge of $935 million recorded in 2016, was estimated based on a determination of the implied fair value of goodwill, leveraging discounted cash flows (level 3). Refer to Note 6 – Goodwill and Intangible Assets, Net for additional information regarding this impairment.

Defined Benefit Plan [Abstract]
Employee Benefit Plans	Employee Benefit Plans Our defined benefit pension plans are primarily associated with certain employees in our Human Resources and Consulting business located in the U.S., Canada and the United Kingdom (U.K.). Prior to an amendment to freeze future service benefits, these defined benefit pension plans had provided benefits for participating employees based on years of service and average compensation for a specified period before retirement (see Plan Amendment below for further information). Certain of our employees participate in post-employment medical plans. These plans are not material to our results of operations or financial position and are not included in the disclosures below. December 31 is the measurement date for all of our defined benefit pension plans.

Plan Amendments Pension Plan Freezes In 2015, we amended several of our major defined benefit pension plans to freeze current benefits and eliminate benefits accruals for future service, including our plans in the U.S., Canada and the U.K. The freeze of current benefits is the primary driver of the reduction in pension service costs since 2015. In certain non-U.S. plans, we are required to continue to consider salary increases and inflation in determining the benefit obligation related to prior service. Plan Assets Current Allocation As of the 2017 and 2016 measurement dates, the global pension plan assets were $222 million and $192 million , respectively. These assets were invested among several asset classes. The following tables presents the defined benefit plans assets measured at fair value and the basis for that measurement: December 31, 2017 (in millions) U.S. Plans Non-U.S. Plans Asset Class Level 1 Level 2 Level 3 Total % Level 1 Level 2 Level 3 Total % Cash and cash equivalents $ 1 $ — $ — $ 1 2 % $ 3 $ — $ — $ 3 2 % Equity Securities 12 31 — 43 69 % — 47 — 47 29 % Fixed Income Securities 18 — — 18 29 % — 46 — 46 29 % Other — — — — — % — 55 9 64 40 % Total Fair Value of Plan Assets $ 31 $ 31 $ — $ 62 100 % $ 3 $ 148 $ 9 $ 160 100 % December 31, 2016 (in millions) U.S. Plans Non-U.S. Plans Asset Class Level 1 Level 2 Level 3 Total % Level 1 Level 2 Level 3 Total % Cash and cash equivalents $ 3 $ — $ — $ 3 6 % $ — $ — $ — $ — — % Equity Securities 9 24 — 33 63 % — 61 — 61 44 % Fixed Income Securities 10 6 — 16 31 % — 60 — 60 43 % Other — — — — — % — 11 8 19 13 % Total Fair Value of Plan Assets $ 22 $ 30 $ — $ 52 100 % $ — $ 132 $ 8 $ 140 100 % Valuation Method Our primary Level 3 assets are Real Estate and Guaranteed Investment Contract investments which are individually immaterial. The fair value of our real estate investment funds are based on the Net Asset Value (NAV) of our ownership interest in the funds. NAV information is received from the investment advisers and is primarily derived from third-party real estate appraisals for the properties owned. The fair value for our Guaranteed Investment Contract investments have been determined based on the higher of the surrender value of the contract or the present value of the cash flow of the related pension obligations. The valuation techniques and inputs for our Level 3 assets have been consistently applied for all periods presented. Investment Strategy The target asset allocations for our worldwide defined benefit pension plans were: 2017 2016 U.S. Non-U.S. U.S. Non-U.S. Equity investments 55% 28% 55% 41% Fixed income investments 23% 43% 25% 45% Real estate —% 4% —% 4% Other 22% 25% 20% 10% Total Investment Strategy 100% 100% 100% 100% We employ a total return investment approach whereby a mix of equities and fixed income investments are used to maximize the long-term return of plan assets for a prudent level of risk. The intent of this strategy is to minimize plan expenses by exceeding the interest growth in long-term plan liabilities. Risk tolerance is established through careful consideration of plan liabilities, plan funded status and corporate financial condition. This consideration involves the use of long-term measures that address both return and risk. The investment portfolio contains a diversified blend of equity and fixed income investments. Furthermore, equity investments are diversified across U.S. and non-U.S. stocks, as well as growth, value and small and large capitalizations. Other assets such as real estate, are used to improve portfolio diversification. Derivatives may be used to hedge market exposure in an efficient and timely manner; however, derivatives may not be used to leverage the portfolio beyond the market value of the underlying investments. Investment risks and returns are measured and monitored on an ongoing basis through annual liability measurements and quarterly investment portfolio reviews. Contributions In 2017 , we made cash contributions of $8 million ( $3 million U.S. and $5 million non-U.S.) to our defined benefit pension plans. In 2018 , based on current actuarial calculations, we expect to make contributions of approximately $8 million ( $8 million non-U.S. and none for U.S.) to our defined benefit pension plans. Estimated Future Benefit Payments The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid during the following years: Pension Benefits (in millions) U.S. Non-U.S. Total 2018 $ 2 $ 4 $ 6 2019 2 5 7 2020 2 5 7 2021 3 5 8 2022 3 5 8 Years 2023-2026 19 30 49 Assumptions Weighted-average assumptions used to determine benefit obligations at the plan measurement dates: Pension Benefits 2017 2016 2015 U.S. Non-U.S. U.S. Non-U.S. U.S. Non-U.S. Discount rate 3.8 % 2.9 % 4.2 % 3.2 % 4.3 % 3.9 % Rate of compensation increase n/a 0.8 % n/a 1.0 % n/a 1.0 % Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31: Pension Benefits 2018 2017 2016 2015 U.S. Non-U.S. U.S. Non-U.S. U.S. Non-U.S. U.S. Non-U.S. Discount rate 3.8 % 3.1 % 4.2 % 3.1 % 4.3 % 3.9 % 4.0 % 3.4 % Expected return on plan assets 7.8 % 4.8 % 7.8 % 4.8 % 7.8 % 5.7 % 7.8 % 5.8 % Rate of compensation increase n/a 0.8 % n/a 0.8 % n/a 1.0 % n/a 1.1 % Defined Contribution Plans We have post-retirement savings and investment plans in several countries, including the U.S., U.K. and Canada. In many instances, employees from those defined benefit pension plans that have been amended to freeze future service accruals (see "Plan Amendments" for additional information) were transitioned to an enhanced defined contribution plan. In these plans employees are allowed to contribute a portion of their salaries and bonuses to the plans, and we match a portion of the employee contributions. We recorded charges related to our defined contribution plans of $35 million in 2017 , $35 million in 2016 and $34 million in 2015 .

Income Tax Disclosure [Abstract]
Income and Other Taxes	Income Taxes Prior to the spin-off from Xerox Corporation, Conduent’s operating results were included in various Xerox consolidated U.S. federal and state income tax returns, as well as non-U.S. tax filings. For the purposes of the Company’s Consolidated and Combined Financial Statements for periods prior to the spin-off, income tax expense and deferred tax balances have been recorded as if the Company filed tax returns on a standalone basis, separate from Xerox. The Separate Return Method applies the accounting guidance for income taxes to the standalone financial statements as if the Company was a separate taxpayer and a standalone enterprise for fiscal 2016 and prior. On December 22, 2017, the Tax Reform was enacted. The effects of changes in tax rates and laws are recognized in the period in which the new legislation is enacted. In the case of US federal income taxes, the enactment date is the date the bill becomes law. The income tax effects of the Tax Reform have been initially accounted for on a provisional basis pursuant to the SEC staff guidance on income taxes. Reasonable estimates for all material tax effects of the Tax Reform (other than amounts related to accounting policy elections) have been provided and adjustments to provisional amounts will be made in subsequent reporting periods as information becomes available to complete provisional computations. With respect to this legislation, we recorded a provisional tax benefit of $198 million , which included a $210 million tax benefit due to the re-measurement of deferred tax assets and liabilities resulting from the decrease in the corporate U.S. federal income tax rate from 35% to 21% , and $12 million as a one-time-charge on the transition tax for Post-1986 undistributed and not previously taxed foreign earnings and profits. The impacts of Tax Reform on our 2017 Consolidated Financial Statements are provisional, and could change during 2018 as we further evaluate the impacts of the Tax Reform. The Company has provisionally adopted the policy of treating the Global Intangible Low Taxed Income (GILTI) regime as a period cost. The GILTI regime enacted as part of Tax Reform subjects certain post 2017 foreign earnings (i.e. amounts in excess of deemed return on net tangible assets of non-US subsidiaries) to US tax. In January 2018, the FASB released guidance on the accounting for tax on GILTI. The guidance indicates that either accounting for deferred taxes on GILTI or treating GILTI as a period cost are both acceptable accounting elections. (Loss) income before income taxes (pre-tax (loss) income) was as follows: Year Ended December 31, (in millions) 2017 2016 2015 Domestic loss $ (91 ) $ (1,329 ) $ (654 ) Foreign income 75 102 80 Loss Before Income Taxes $ (16 ) $ (1,227 ) $ (574 ) (Benefit) provision for income taxes were as follows: Year Ended December 31, (in millions) 2017 2016 2015 Federal Income Taxes Current $ 4 $ (116 ) $ (130 ) Deferred (233 ) (132 ) (99 ) Foreign Income Taxes Current 25 31 24 Deferred (3 ) (3 ) 6 State Income Taxes Current 8 1 (17 ) Deferred 6 (25 ) (22 ) Total Benefit $ (193 ) $ (244 ) $ (238 ) A reconciliation of the U.S. federal statutory income tax rate to the consolidated effective income tax rate is as follows: Year Ended December 31, 2017 2016 2015 U.S. federal statutory income tax rate 35.0 % 35.0 % 35.0 % Nondeductible expenses (1) (155.9 )% (19.0 )% (1.3 )% Effect of tax law changes 1,282.4 % — % 0.9 % Change in valuation allowance for deferred tax assets (39.5 )% 0.1 % (1.0 )% State taxes, net of federal benefit 1.2 % 1.8 % 4.2 % Audit and other tax return adjustments — % 1.4 % 0.1 % Tax-exempt income, credits and incentives 38.9 % 0.7 % 0.7 % Foreign rate differential adjusted for U.S. taxation of foreign profits (2) 47.7 % 0.7 % 2.4 % Other (3.5 )% (0.8 )% 0.5 % Effective Income Tax Rate 1,206.3 % 19.9 % 41.5 % ____________ (1) In 2017, nondeductible expenses primarily related to the nondeductible portion of the goodwill and officers life insurance.

On a consolidated basis, we paid/(received) a total of $29 million , $(123) million and $194 million in income taxes to federal, foreign and state jurisdictions during the three years ended December 31, 2017 , 2016 and 2015 , respectively. Total income tax expense (benefit) was allocated as follows: Year Ended December 31, (in millions) 2017 2016 2015 Pre-tax income $ (193 ) $ (244 ) $ (238 ) Discontinued operations (1) 3 — 81 Common shareholders' equity: Changes in defined benefit plans — 8 2 Stock option and incentive plans, net — — (6 ) Total Income Tax Benefit $ (190 ) $ (236 ) $ (161 ) _____________ (1) Refer to Note 3 – Assets/Liabilities Held for Sale for additional information regarding discontinued operations. Unrecognized Tax Benefits and Audit Resolutions We recognize tax liabilities when, despite our belief that our tax return positions are supportable, we believe that certain positions may not be fully sustained upon review by tax authorities. Each period we assess uncertain tax positions for recognition, measurement and effective settlement. Benefits from uncertain tax positions are measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement. Where we have determined that our tax return filing position does not satisfy the more-likely-than-not recognition threshold, we have recorded no tax benefits. We are also subject to ongoing tax examinations in numerous jurisdictions due to the extensive geographical scope of our operations. Our ongoing assessments of the more-likely-than-not outcomes of the examinations and related tax positions require judgment and can increase or decrease our effective tax rate, as well as impact our operating results. The specific timing of when the resolution of each tax position will be reached is uncertain. As of December 31, 2017 , we do not believe that there are any positions for which it is reasonably possible that the total amount of unrecognized tax benefits will significantly increase or decrease within the next 12 months. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: (in millions) 2017 2016 2015 Balance at January 1 $ 14 $ 24 $ 32 Additions related to current year — 1 3 Additions related to prior years positions — — — Reductions related to prior years positions — (5 ) (10 ) Settlements with taxing authorities (1) — (5 ) — Currency 1 (1 ) (1 ) Balance at December 31 $ 15 $ 14 $ 24 _______________ (1) 2016 settlement results in $5 million cash paid. Included in the balances at December 31, 2017 , 2016 and 2015 are $0 , $0 and $8 million , respectively, of tax positions that are highly certain of realization but for which there is uncertainty about the timing. Because of the impact of deferred tax accounting, other than for the possible incurrence of interest and penalties, the disallowance of these positions would not affect the annual effective tax rate. In addition, for other uncertain tax positions, we maintain offsetting benefits from other jurisdictions of $16 million , $16 million and $14 million , at December 31, 2017 , 2016 and 2015 , respectively. We recognized interest and penalties accrued on unrecognized tax benefits, as well as interest received from favorable settlements within income tax expense. We had $6 million , $4 million and $14 million accrued for the payment of interest and penalties associated with unrecognized tax benefits at December 31, 2017 , 2016 and 2015 , respectively. In the U.S., we are no longer subject to U.S. federal income tax examinations for years before 2005. With respect to our major foreign jurisdictions, the years generally remain open back to 2006. Deferred Income Taxes The Company is in the position of having tax basis in excess of book basis in its U.S. investment in foreign subsidiaries. Nonetheless, the Company is indefinitely reinvesting its foreign subsidiaries' undistributed earnings of $253 million . For years after 2017, the Tax Reform does allow for certain earnings to be repatriated free from US Federal taxes. However, the repatriation of earnings could give rise to additional tax liabilities. The tax effects of temporary differences that give rise to significant portions of the deferred taxes were as follows: December 31, (in millions) 2017 2016 Deferred Tax Assets Net operating losses $ 41 $ 42 Operating reserves, accruals and deferrals 90 155 Deferred compensation 59 101 Pension 15 18 Other 45 44 Subtotal 250 360 Valuation allowance (35 ) (24 ) Total $ 215 $ 336 Deferred Tax Liabilities Unearned income $ 134 $ 217 Intangibles and goodwill 413 680 Depreciation 10 15 Other 25 29 Total $ 582 $ 941 Total Deferred Taxes, Net $ (367 ) $ (605 ) The deferred tax assets for the respective periods were assessed for recoverability and, where applicable, a valuation allowance was recorded to reduce the total deferred tax asset to an amount that will, more-likely-than-not, be realized in the future. The net change in the total valuation allowance for the years ended December 31, 2017 and 2016 was an increase of $11 million and a decrease of $14 million , respectively. The valuation allowance relates primarily to certain net operating loss carryforwards, tax credit carryforwards and deductible temporary differences for which we have concluded it is more-likely-than-not that these items will not be realized in the ordinary course of operations. Although realization is not assured, we have concluded that it is more-likely-than-not that the deferred tax assets, for which a valuation allowance was determined to be unnecessary, will be realized in the ordinary course of operations based on the available positive and negative evidence, including scheduling of deferred tax liabilities and projected income from operating activities. The amount of the net deferred tax assets considered realizable, however, could be reduced in the near term if actual future income or income tax rates are lower than estimated, or if there are differences in the timing or amount of future reversals of existing taxable or deductible temporary differences. At December 31, 2017 , we had tax credit carryforwards of $27 million available to offset future income taxes which will expire between 2018 and 2037 if not utilized. We also had net operating loss carryforwards for income tax purposes of $422 million that will expire between 2018 and 2037, if not utilized; and $43 million available to offset future taxable income indefinitely.

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Litigation	Contingencies and Litigation As more fully discussed below, we are involved in a variety of claims, lawsuits, investigations and proceedings concerning: securities law; governmental entity contracting, servicing and procurement law; intellectual property law; environmental law; employment law; the Employee Retirement Income Security Act (ERISA); and other laws and regulations. We determine whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed probable and can be reasonably estimated. We assess our potential liability by analyzing our litigation and regulatory matters using available information. We develop our views on estimated losses in consultation with outside counsel handling our defense in these matters, which involves an analysis of potential results, assuming a combination of litigation and settlement strategies. Should developments in any of these matters cause a change in our determination as to an unfavorable outcome and result in the need to recognize a material accrual, or should any of these matters result in a final adverse judgment or be settled for significant amounts, this could have a material adverse effect on our results of operations, cash flows and financial position in the period or periods in which such change in determination, judgment or settlement occurs. We believe that we have recorded adequate provisions for any such matters as of December 31, 2017 . Litigation is inherently unpredictable, and it is not possible to predict the ultimate outcome of these matters and such outcome in any such matter could be in excess of any amounts accrued and could be material to our results of operations, cash flows or financial position in any reporting period. Additionally, guarantees, indemnifications and claims arise during the ordinary course of business from relationships with suppliers, customers and nonconsolidated affiliates when we undertake an obligation to guarantee the performance of others if specified triggering events occur. Nonperformance under a contract could trigger an obligation of the Company. These potential claims include actions based upon alleged exposures to products, real estate, intellectual property such as patents, environmental matters and other indemnifications. The ultimate effect on future financial results is not subject to reasonable estimation because considerable uncertainty exists as to the final outcome of these claims. However, while the ultimate liabilities resulting from such claims may be significant to results of operations in the period recognized, management does not anticipate they will have a material adverse effect on the consolidated financial position or liquidity. As of December 31, 2017 , we have accrued our estimate of liability incurred under our indemnification arrangements and guarantees. Litigation Against the Company State of Texas v. Xerox Corporation, Xerox State Healthcare, LLC, and ACS State Healthcare, LLC: On May 9, 2014, the State of Texas, via the Texas Office of Attorney General (the “State”), filed a lawsuit in the 53rd Judicial District Court of Travis County, Texas. The lawsuit alleges that Xerox Corporation, Xerox State Healthcare, LLC and ACS State Healthcare (collectively, the "Xerox Defendants") violated the Texas Medicaid Fraud Prevention Act in the administration of its contract with the Texas Department of Health and Human Services (“HHSC”). The State alleges that the Xerox Defendants made false representations of material facts regarding the processes, procedures, implementation and results regarding the prior authorization of orthodontic claims. The State seeks recovery of amounts paid for orthodontic treatment under the Texas Medicaid program for the period from approximately 2004 to 2012, three times the amount of the payments made as a result of the alleged unlawful acts, civil penalties, pre- and post-judgment interest and all costs and attorneys’ fees. The Xerox Defendants filed their Answer in June, 2014 denying all allegations. A trial date is scheduled for November, 2018. During the first quarter of 2018, the State notified the Xerox Defendants in the litigation discovery process that its claim is in excess of two billion dollars based primarily on the assertion of treble damages and civil penalties per illegal act for almost two hundred thousand purported illegal acts. The Xerox Defendants will forcefully contest this assertion and continue to vigorously defend themselves in this matter. We are not able to determine or predict the ultimate outcome of this proceeding or to estimate any reasonably possible loss or range of losses, if any, in excess of the thirty-eight million dollars we have already accrued. In the course of litigation, we periodically engage in discussions with the State's counsel for possible resolution of the matter. Should developments cause a change in our determination as to an unfavorable outcome, or result in a final adverse judgment or settlement for a significant amount, there could be a material adverse effect on our results of operations, cash flows and financial position in the period in which such change in determination, judgment or settlement occurs. Dennis Nasrawi v. Buck Consultants et al.: On October 8, 2009, plaintiffs filed a lawsuit in the Superior Court of California, Stanislaus County, and on November 24, 2009, the case was removed to the U.S. Court for the Eastern District of California, Fresno Division. Plaintiffs allege actuarial negligence against Buck Consultants, LLC (“Buck”), a wholly-owned subsidiary of Conduent, for the use of faulty actuarial assumptions in connection with the 2007 actuarial valuation for the Stanislaus County Employees Retirement Association (“StanCERA”). Plaintiffs allege that the employer contribution rate adopted by StanCERA based on Buck’s valuation was insufficient to fund the benefits promised by the County. On July 13, 2012, the Court entered its ruling that the plaintiffs lacked standing to sue in a representative capacity on behalf of all plan participants. The Court also ruled that plaintiffs had adequately pleaded their claim that Buck allegedly aided and abetted StanCERA in breaching its fiduciary duty. Plaintiffs then filed their Fifth Amended Complaint and added StanCERA to the litigation. Buck and StanCERA filed demurrers to the amended complaint. On September 13, 2012, the Court sustained both demurrers with prejudice, completely dismissing the matter and barring plaintiffs from refiling their claims. Plaintiffs appealed, and ultimately the California Court of Appeals (Sixth District) reversed the trial court’s ruling and remanded the case back to the trial court. Buck will continue to aggressively defend these lawsuits. We are not able to determine or predict the ultimate outcome of this proceeding or reasonably provide an estimate or range of estimate of the possible outcome or loss, if any. Conduent Business Services, LLC v. Cognizant Business Services, LLC: On April 12, 2017, Conduent Business Services LLC (“Conduent”) filed a lawsuit against Cognizant Business Services Corporation (“Cognizant”) in the Supreme Court of New York County, New York. The lawsuit relates to the Amended and Restated Master Outsourcing Services Agreement effective as of October 24, 2012, and the service delivery contracts and work orders thereunder, between Conduent and Cognizant, as amended and supplemented (the “Contract”). The Contract contains certain minimum purchase obligations by Conduent through the date of expiration. The lawsuit alleges that Cognizant committed multiple breaches of the Contract, including Cognizant’s failure to properly perform its obligations as subcontractor to Conduent under Conduent’s contract with the New York Department of Health to provide a Medicaid Management Information Systems (the “NY MMIS Contract”). In the lawsuit, Conduent seeks damages in excess of one hundred fifty million dollars . During the first quarter of 2018, Conduent provided notice to Cognizant that it was terminating the Contract for cause and will be recording in that period certain charges associated with the termination. Cognizant has asserted counterclaims against Conduent in the lawsuit seeking damages in excess of twenty-two million dollars . Conduent has responded to Cognizant’s counterclaims by denying the allegations. Conduent will continue to vigorously defend itself against the counterclaims but we are not able to determine or predict the ultimate outcome of this proceeding or reasonably provide an estimate or range of estimate of the possible outcome. Other Matters: On January 5, 2016, the Consumer Financial Protection Bureau (the "CFPB") notified Xerox Education Services, Inc. (XES) that, in accordance with the CFPB’s discretionary Notice and Opportunity to Respond and Advise (NORA) process, the CFPB’s Office of Enforcement is considering recommending that the CFPB take legal action against XES, alleging that XES violated the Consumer Financial Protection Act’s prohibition of unfair practices. Should the CFPB commence an action, it may seek restitution, civil monetary penalties, injunctive relief or other corrective action. The purpose of a NORA letter is to provide a party being investigated an opportunity to present its position to the CFPB before an enforcement action is recommended or commenced. This notice stems from an inquiry that commenced in 2014 when XES received and responded to a Civil Investigative Demand containing a broad request for information. During this process, XES self-disclosed to the Department of Education and the CFPB certain adjustments of which it had become aware that had not been timely made relating to its servicing of a small percentage of third-party student loans under outsourcing arrangements for various financial institutions. The CFPB and the Department of Education, as well as certain states' attorney general offices and other regulatory agencies, began similar reviews. XES has cooperated and continues to fully cooperate with all regulatory agencies, and XES has submitted its NORA response. We cannot provide assurance that the CFPB or another party will not ultimately commence a legal action against XES in this matter nor are we able to predict the likely outcome of the investigations into this matter or reasonably provide an estimate or range of estimate of possible outcome or loss, if any. We could in future periods incur judgments or enter into settlements in connection with this matter and there could be a material adverse effect on our results of operations, cash flows and financial position in the period in which such change in judgment or settlement occurs. Guarantees, Indemnifications and Warranty Liabilities Indemnifications Provided as Part of Contracts and Agreements Acquisitions/Divestitures: We have indemnified, subject to certain deductibles and limits, the purchasers of businesses or divested assets for the occurrence of specified events under certain of our divestiture agreements. In addition, we customarily agree to hold the other party harmless against losses arising from a breach of representations and covenants, including such matters as adequate title to assets sold, intellectual property rights, specified environmental matters and certain income taxes arising prior to the date of acquisition. Where appropriate, an obligation for such indemnifications is recorded as a liability at the time of the acquisition or divestiture. Since the obligated amounts of these types of indemnifications are often not explicitly stated or are contingent on the occurrence of future events, the overall maximum amount of the obligation under such indemnifications cannot be reasonably estimated. Other than obligations recorded as liabilities at the time of divestiture, we have not historically made significant payments for these indemnifications. Additionally, under certain of our acquisition agreements, we have provided for additional consideration to be paid to the sellers if established financial targets are achieved post-closing. We have recognized liabilities for these contingent obligations based on an estimate of the fair value of these contingencies at the time of acquisition. Contingent obligations related to indemnifications arising from our divestitures and contingent consideration provided for by our acquisitions are not expected to be material to our financial position, results of operations or cash flows. Other Agreements: We are also party to the following types of agreements pursuant to which we may be obligated to indemnify the other party with respect to certain matters: • Guarantees on behalf of our subsidiaries with respect to real estate leases. These lease guarantees may remain in effect subsequent to the sale of the subsidiary. • Agreements to indemnify various service providers, trustees and bank agents from any third-party claims related to their performance on our behalf, with the exception of claims that result from the third-party's own willful misconduct or gross negligence. • Guarantees of our performance in certain services contracts to our customers and indirectly the performance of third parties with whom we have subcontracted for their services. This includes indemnifications to customers for losses that may be sustained as a result of our performance of services at a customer's location. In each of these circumstances, our payment is conditioned on the other party making a claim pursuant to the procedures specified in the particular contract and such procedures also typically allow us to challenge the other party's claims. In the case of lease guarantees, we may contest the liabilities asserted under the lease. Further, our obligations under these agreements and guarantees may be limited in terms of time and/or amount, and in some instances, we may have recourse against third parties for certain payments we made. Also in December 2017, a customer released our former parent company from a performance guarantee for a service contract resulting in a release of escrow funds of $15 million to the Company. Intellectual Property Indemnifications We do not own most of the software that we use to run our business. Instead, we license this software from a small number of primary vendors. We indemnify certain software providers against claims that may arise as a result of our use or our subsidiaries', customers' or resellers' use of their software in our services and solutions. These indemnities usually do not include limits on the claims, provided the claim is made pursuant to the procedures required in the services contract. Indemnification of Officers and Directors Our corporate by-laws require that, except to the extent expressly prohibited by law, we must indemnify our officers and directors against judgments, fines, penalties and amounts paid in settlement and reasonable expenses, including attorneys' fees, incurred in connection with civil or criminal action or proceedings or any appeal, as it relates to their services to our Company and our subsidiaries. Although the by-laws provide no limit on the amount of indemnification, we may have recourse against our insurance carriers for certain payments made by us. However, certain indemnification payments (such as those related to "clawback" provisions in certain compensation arrangements) may not be covered under our directors' and officers' insurance coverage. We also indemnify certain fiduciaries of our employee benefit plans for liabilities incurred in their service as fiduciary whether or not they are officers of the Company. Finally, in connection with our acquisition of businesses, we may become contractually obligated to indemnify certain former and current directors, officers and employees of those businesses in accordance with pre-acquisition by-laws or indemnification agreements or applicable state law. Other Contingencies Certain contracts, primarily in our Public Sector segment, require us to provide a surety bond or a letter of credit as a guarantee of performance. As of December 31, 2017 , we had $576 million for outstanding surety and bid bonds used to secure our performance of contractual obligations with our clients, and we had $256 million of outstanding letters of credit issued to secure our performance of contractual obligations to our clients as well as other corporate obligations. In general, we would only be liable for the amount of these guarantees in the event of default in our performance of our obligations under each contract. We believe we have sufficient capacity in the surety markets and liquidity from our cash flow and our various credit arrangements (including our Credit Facility) to allow us to respond to future requests for proposals that require such credit support. We have service arrangements where we service third-party student loans in the Federal Family Education Loan program (FFEL) on behalf of various financial institutions. We service these loans for investors under outsourcing arrangements and do not acquire any servicing rights that are transferable by us to a third-party. At December 31, 2017 , we serviced a FFEL portfolio of loans with an outstanding principal balance of approximately $ 5.2 billion . Some servicing agreements contain provisions that, under certain circumstances, require us to purchase the loans from the investor if the loan guaranty has been permanently terminated as a result of a loan default caused by our servicing error. If defaults caused by us are cured during an initial period, any obligation we may have to purchase these loans expires. Loans that we purchase may be subsequently cured, the guaranty reinstated and the loans repackaged for sale to third parties. We evaluate our exposure under our purchase obligations on defaulted loans and establish a reserve for potential losses. The reserve is evaluated periodically and adjusted based upon management’s analysis of the historical performance of the defaulted loans. As of December 31, 2017 , other current liabilities include reserves of approximately $1 million , which we believe to be adequate. In addition to potential purchase obligations arising from servicing errors, various laws and regulations applicable to student loan borrowers could give rise to fines, penalties and other liabilities associated with loan servicing errors.

Equity [Abstract]
Preferred Stock	Preferred Stock Series A Preferred Stock In connection with the December 31, 2016 spin-off from Xerox Corporation, we issued 120 thousand shares of Series A convertible perpetual preferred stock with an aggregate liquidation preference of $120 million and an initial fair value of $142 million . The convertible preferred stock pays quarterly cash dividends at a rate of 8% per year ( $9.6 million per year). Each share of convertible preferred stock is convertible at any time, at the option of the holder, into 44.9438 shares of common stock for a total of 5,393 thousand shares (reflecting an initial conversion price of approximately $22.250 per share of common stock), subject to customary anti-dilution adjustments. If the closing price of our common stock exceeds 137% of the initial conversion price for 20 out of 30 trading days, we have the right to cause any or all of the convertible preferred stock to be converted into shares of common stock at the then applicable conversion rate. The convertible preferred stock is also convertible, at the option of the holder, upon a change in control, at the applicable conversion rate plus an additional number of shares determined by reference to the price paid for our common stock upon such change in control. In addition, upon the occurrence of certain fundamental change events, including a change in control or the delisting of Conduent's common stock, the holder of convertible preferred stock has the right to require us to redeem any or all of the convertible preferred stock in cash at a redemption price per share equal to the liquidation preference and any accrued and unpaid dividends to, but not including, the redemption date. As a result of the contingent redemption feature, the convertible preferred stock is classified as temporary equity and reflected separately from permanent equity in the Consolidated Balance Sheets.

Stockholders' Equity Note [Abstract]
Shareholders' Equity	Shareholders’ Equity Preferred Stock As of December 31, 2017 , we had one class of preferred stock outstanding. See Note 14 – Preferred Stock for further information. We are authorized to issue approximately 100 million shares of cumulative preferred stock at $0.01 par value per share. Common Stock We have 1 billion authorized shares of common stock at $0.01 par value per share. At December 31, 2017 , 15 million shares were reserved for issuance under our incentive compensation plans and 5.4 million shares were reserved for conversion of the Series A convertible preferred stock. Stock Compensation Plans Certain of our employees participate in a long-term incentive plan. Our long-term incentive plan authorizes the issuance of restricted stock units / shares (RSU), performance stock units / share (PSU) and non-qualified stock options to employees. All awards for these plans prior to 2017, were made in Xerox stock and therefore converted into Conduent stock effective upon the Separation. Using a formula designed to preserve the value of the award immediately prior to the Separation, all of these awards will be settled and are reflected in Conduent's Consolidated Statements of Stockholders' Equity. Stock-based compensation expense includes expense based on the awards and terms previously granted to the employees. Stock-based compensation expense was as follows: Year Ended December 31, (in millions) 2017 2016 2015 Stock-based compensation expense, pre-tax $ 42 $ 23 $ 19 Income tax benefit recognized in earnings 17 9 7 Restricted Stock Units / Shares Compensation expense is based upon the grant date market price. The compensation expense is recorded over the vesting period, which is normally three years from the date of grant, based on management's estimate of the number of shares expected to vest. Performance Stock Units / Shares: The Company granted PSUs that vest contingent upon its achievement of certain specified financial performance criteria over a three -year period. If the three -year actual results exceed the stated targets, then the plan participants have the potential to earn additional shares of common stock, which cannot exceed 100% of the original grant. The fair value of PSUs is based upon the market price of Conduent's common stock on the date of the grant and then converted to Conduent's common stock upon the Separation. Compensation expense is recognized over the vesting period, which is normally three years from the date of grant, based on management's estimate of the number of shares expected to vest. If the stated targets are not met, any recognized compensation cost would be reversed. Employee Stock Options: Stock options were issued by a former parent company and were converted to Conduent's common stock upon the Separation. These options generally expire within the next two years. Other than these options, Conduent has not issued any new stock options.

Related Party and Former Parent Investment [Abstract]
Related Party Transactions Disclosure [Text Block]	Related Party Transactions and Former Parent Company Investment Allocation of Corporate Expenses The Consolidated Statements of Income (Loss), Consolidated Statements of Comprehensive Income (Loss) and Consolidated Statements of Cash Flows for the years ended December 31, 2016 and 2015 include an allocation of general corporate expenses from Xerox, the Company's former parent. The financial information in these Consolidated Financial Statements does not necessarily include all the expenses that would have been incurred or held had we been a separate, standalone company and it is not practicable to estimate actual costs that would have been incurred had we been a separate, standalone company during the periods presented. Management considers these allocations to be a reasonable reflection of the utilization of services by, or the benefits provided. Allocations for management costs and corporate support services provided totaled $165 million and $170 million for the years ended December 31, 2016 and 2015, respectively. These amounts include costs for corporate functions including, but not limited to, senior management, legal, human resources, finance and accounting, treasury, information technology and other shared services. Where possible, these costs were allocated based on direct usage, with the remainder allocated on a basis of costs, headcount and/or other measures we have determined as reasonable.

The purpose of these notes was to provide funds for certain working capital or other capital and operating requirements of the business. Net interest expense on these notes with related party companies was recorded net in Related Party Interest in the Consolidated Statements of Income (Loss) and was $26 million and $61 million for the years ended December 31, 2016 and 2015, respectively. These notes had fixed interest rates that ranged from 1% to 8% . The balances were settled as part of the Separation transaction. Related Party Revenue and Purchases We provide various services to Xerox Corporation, including those related to human resources, accounting and finance and customer care, which are reported as Related party revenue in the Consolidated Statements of Income (Loss). The costs related to these services are reported as Related party cost of services in the Consolidated Statements of Income (Loss). We also leased equipment and received related services, supplies and parts, from Xerox and Xerox subsidiaries in the amount of $21 million and $24 million , for the years ended December 31, 2016 and 2015, respectively. The costs related to these services, supplies and parts are reported in Cost of services and Selling, administrative and general expenses in the Consolidated Statements of Income (Loss).

Basis of Presentation and Sum26

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Consolidation	Basis of Presentation Our Consolidated Financial Statements included the historical basis of assets, liabilities, revenues and expenses of the individual businesses of the Company, including joint ventures and partnerships over which the Company has a controlling financial interest. We have prepared the Consolidated Financial Statements pursuant to the rules and regulations of the SEC. Certain reclassifications have been made to prior years to conform to the current year presentation. All intercompany transactions and balances have been eliminated. We have also considered the impact of subsequent events on these consolidated financial statements. Separation from Xerox Corporation On December 31, 2016, Conduent spun-off from Xerox Corporation (Xerox), pursuant to the Separation and Distribution Agreement (Separation). The Separation was completed by way of a pro rata distribution of Conduent shares held by Xerox to Xerox’s shareholders. As a result, we operate as an independent, publicly traded company on the New York Stock Exchange, under the ticker "CNDT". Prior to December 31, 2016, the Financial Statements of the Company were derived from the financial statements and accounting records of Xerox as if the Conduent operated on a standalone basis. Historically, the Company consisted of the Business Process Outsourcing Operating segment within Xerox’s reportable Services segment and did not operate as a separate, standalone company. Accordingly, Xerox performed certain corporate overhead functions for the Company. Therefore, certain corporate costs, including compensation costs for corporate employees supporting the Company, were allocated from Xerox. It is not practicable to estimate actual costs that would have been incurred had the Company been a separate standalone company during the periods presented. Allocations for management costs and corporate support services provided to the Company totaled $165 million and $170 million for years ended December 31, 2016 and December 31, 2015, respectively. Management of the Company believes the assumptions regarding the allocated expenses reasonably reflect the utilization of services provided to or the benefit received by the Company during the periods prior to the Separation. The Consolidated Financial Statements for the periods prior to the Separation do not necessarily include all the expenses that would have been incurred or held by the Company had it been a separate, standalone company.
Use of Estimates	Use of Estimates We prepared the Consolidated Financial Statements using financial information available at the time of preparation, which requires us to make estimates and assumptions that affect the amounts reported. Our most significant estimates pertain to the recognition of revenue for contracts based on the percentage of completion method of accounting, intangible and long-lived assets, valuation of goodwill, contingencies and litigation, income taxes and corporate allocations (for years ended December 31, 2016 and 2015). Our estimates are based on management's best knowledge of current events, historical experience, and on various other assumptions that are believed to be reasonable under the circumstances. As a result, actual results may be different from these estimates.
Revenue Recognition, Customer Acquisitions	Revenue Recognition: In May 2014, the Financial Accounting Standards Board (FASB) updated the accounting guidance related to revenue recognition to clarify the principles for recognizing revenue and replaced all existing revenue recognition guidance in U.S. GAAP with one accounting model. The core principle of the guidance is that an entity should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated guidance also requires additional qualitative and quantitative disclosures relating to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers largely on a disaggregated basis. We have evaluated the adoption impact of the updated accounting guidance on our consolidated financial statements and continue to evaluate the impact on disclosures and internal controls. The new guidance will impact: (1) revenue associated with postage, which will be recognized on a net basis versus the current gross treatment; (2) the timing of revenue recognition associated with fixed fees for certain contracts with more than one performance obligation; and (3) the timing of recognition of certain pricing discounts. We adopted this updated accounting guidance beginning January 1, 2018 using the modified retrospective method under which we will recognize a cumulative-effect adjustment of approximately $20 million at the date of adoption (the expected impact to 2018 revenues is approximately $15 million ), which excludes changes to our revenue associated with the reimbursement of postage. In addition, we recognized approximately $150 million of postage revenue in 2017 that will be recognized on a net basis (for all future periods) in Cost of services.
New Accounting Pronouncements, Policy	New Accounting Standards Revenue Recognition: In May 2014, the Financial Accounting Standards Board (FASB) updated the accounting guidance related to revenue recognition to clarify the principles for recognizing revenue and replaced all existing revenue recognition guidance in U.S. GAAP with one accounting model. The core principle of the guidance is that an entity should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated guidance also requires additional qualitative and quantitative disclosures relating to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers largely on a disaggregated basis. We have evaluated the adoption impact of the updated accounting guidance on our consolidated financial statements and continue to evaluate the impact on disclosures and internal controls. The new guidance will impact: (1) revenue associated with postage, which will be recognized on a net basis versus the current gross treatment; (2) the timing of revenue recognition associated with fixed fees for certain contracts with more than one performance obligation; and (3) the timing of recognition of certain pricing discounts. We adopted this updated accounting guidance beginning January 1, 2018 using the modified retrospective method under which we will recognize a cumulative-effect adjustment of approximately $20 million at the date of adoption (the expected impact to 2018 revenues is approximately $15 million ), which excludes changes to our revenue associated with the reimbursement of postage. In addition, we recognized approximately $150 million of postage revenue in 2017 that will be recognized on a net basis (for all future periods) in Cost of services. Leases: In February 2016, the FASB updated the accounting guidance related to leases requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases except short term leases (lease term of 12 months or less). The accounting for lessors is largely unchanged. This updated guidance is effective for us beginning January 1, 2019. This guidance must be adopted using a modified retrospective approach through a cumulative-effect adjustment for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. While we are currently evaluating the impact of the updated accounting guidance on our consolidated financial statements; we do expect a material impact to the Company's Consolidated Balance Sheets. Cash Flows: In November 2016 the FASB issued updated accounting guidance regarding the presentation of restricted cash in the statement of cash flows. Specifically, this update requires that restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. At December 31, 2017 and 2016 , we had $9 million and $22 million of restricted cash, respectively, reported in other current assets. This update is effective for us beginning January 1, 2018. Business Combinations: In January 2017, the FASB issued clarifying accounting guidance related to the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This update is effective for us beginning January 1, 2018, with early adoption permitted. The amendment in this update will be applied prospectively. There will be no material impact from the adoption of this clarifying accounting guidance on our consolidated financial statements. Recently Adopted Accounting Standards Goodwill: In January 2017, the FASB issued updated accounting guidance for simplifying the goodwill impairment test. Under the new guidance, an entity does not have to calculate the implied fair value of goodwill at the impairment testing date of its assets and liabilities as if those assets and liabilities had been acquired in a business combination. Instead the goodwill impairment test will compare the fair value of a reporting unit with its carrying amount and recognize as an impairment charge any amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit. We have elected to early adopt this new guidance for our goodwill impairment tests performed after January 1, 2017. Adoption did not have any effect on our financial condition, results of operations or cash flows.
Revenue Recognition	Revenue Recognition We primarily generate revenue through services. Revenue is recognized when it is realized or realizable and earned. We consider revenue realized or realizable and earned when we have persuasive evidence of an arrangement, delivery has occurred, the transaction price is fixed or determinable and collectibility is reasonably assured. Delivery does not occur until services have been provided to the customer, risk of loss has transferred to the customer, and either customer acceptance has been obtained, customer acceptance provisions have lapsed or the company has objective evidence that the criteria specified in the customer acceptance provisions have been satisfied. The transaction price is not considered to be fixed or determinable until all contingencies related to the sale have been resolved.
Services-Related Revenue	Outsourcing Services: Revenues associated with outsourcing services are generally recognized as services are rendered, which is generally on the basis of the number of accounts or transactions processed. In service arrangements where final acceptance of a system or solution by the customer is required, revenue is deferred until all acceptance criteria have been met. Revenues on cost reimbursable contracts are recognized by applying an estimated factor to costs as incurred, determined by the contract provisions and prior experience. Revenues on unit-price contracts are recognized at the contractual selling prices as work is completed and accepted by the customer. Revenues on time and material contracts are recognized at the contractual rates as the labor hours and direct expenses are incurred. Revenues on certain fixed price contracts where we provide system development and implementation services are recognized over the contract term based on the percentage of development and implementation services that are provided during the period compared with the total estimated development and implementation services to be provided over the entire contract using the percentage-of-completion accounting methodology. These services require that we perform significant, extensive and complex design, development, modification or implementation of our customers' systems. Performance will often extend over long periods, and our right to receive future payment depends on our future performance in accordance with the agreement. The percentage-of-completion methodology involves recognizing probable and reasonably estimable revenue using the percentage of services completed, on a current cumulative cost to an estimated total cost basis, using a reasonably consistent profit margin over the period. Revenues earned in excess of related billings are accrued, whereas billings in excess of revenues earned are deferred until the related services are provided. We recognize revenues for non-refundable, upfront implementation fees on a straight-line basis over the period between the initiation of the services through the end of the contract term. In connection with our services arrangements, we incur and capitalize costs to originate these long-term contracts and to perform the migration, transition and setup activities necessary to enable us to perform under the terms of the arrangement. Certain initial direct costs of an arrangement are capitalized and amortized over the contractual service period of the arrangement to cost of services. From time to time, we also provide inducements to customers in various forms, including contractual credits, which are capitalized and amortized as a reduction of revenue over the term of the contract. Spending associated with customer-related deferred set-up/transition and inducement costs were as follows: Year Ended December 31, (in millions) 2017 2016 2015 Set-up/transition and inducement expenditures $ 55 $ 63 $ 65 The capitalized amount of customer contract costs were as follows: Year Ended December 31, (in millions) 2017 2016 Capitalized customer contract costs (1) 126 137 __________ (1) The balance at December 31, 2017 and 2016 are expected to be amortized over a weighted average period of approximately nine and eight years, respectively. Amortization expense for the next five years and thereafter is expected to be as follows (in millions): 2018 2019 2020 2021 2022 Thereafter $ 54 $ 22 $ 13 $ 9 $ 6 $ 22 Long-lived assets used in the fulfillment of the arrangements are capitalized and depreciated over the shorter of their useful life or the term of the contract if an asset is contract specific.
Multiple Element Arrangements	Multiple Element Arrangements: As described above, we enter into the following revenue arrangements that may consist of multiple deliverables including contracts for multiple types of outsourcing services, as well as professional and value-added services. For instance, we may contract for an implementation or development project and also provide services to operate the system which we implement or develop over a period of time; or we may contract to scan, manage and store customer documents. In substantially all of our multiple element arrangements, we are able to separate the deliverables since we normally will meet both of the following criteria: • The delivered item(s) has value to the customer on a stand-alone basis; and • If the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in our control. Consideration in a multiple-element arrangement is allocated at the inception of the arrangement to all deliverables on the basis of the relative selling price. When applying the relative selling price method, the selling price for each deliverable is primarily determined based on vendor-specific objective evidence (VSOE), third-party evidence (TPE), or our best estimate of the selling price. The above noted revenue policies are then applied to each separated deliverable, as applicable. Revenue Reporting: Revenue from sales of third-party vendor products or services is recorded net of costs when the Company is acting as an agent between the customer and the vendor or supplier, or gross when the Company is a principal to the transaction. Postage is generally recognized on a gross basis. Several factors are considered to determine whether the company is an agent or principal, most notably whether the Company is the primary obligor to the customer, or has inventory risk. Consideration is also given to whether the Company adds meaningful value to the vendor’s product or service, was involved in the selection of the vendor’s product or service, has latitude in establishing the sales price or has credit risk.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand, including money market funds and investments with original maturities of three months or less.
Receivable Sales	Receivable Sales We had transferred certain portions of our receivable portfolios in 2016 and 2015 and accounted for those transfers as sales based on meeting the criteria for derecognition. Losses on the sale of receivables depend, in part, on both (a) the cash proceeds and (b) the net non-cash proceeds received or paid. When we have sold receivables, we normally received beneficial interests in the transferred receivables from the purchasers as part of the proceeds. Refer to Note 4 – Accounts Receivable, Net for more details on our receivable sales .
Transfers and Servicing of Financial Assets, Transfers of Financial Assets, Sales, Policy	Receivable Sales We had transferred certain portions of our receivable portfolios in 2016 and 2015 and accounted for those transfers as sales based on meeting the criteria for derecognition. Losses on the sale of receivables depend, in part, on both (a) the cash proceeds and (b) the net non-cash proceeds received or paid. When we have sold receivables, we normally received beneficial interests in the transferred receivables from the purchasers as part of the proceeds. Refer to Note 4 – Accounts Receivable, Net for more details on our receivable sales .
Land, Buildings and Equipment and Equipment on Operating Leases	Land, Buildings and Equipment Land, buildings and equipment are recorded at cost. Buildings and equipment are depreciated over their estimated useful lives. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life. Significant improvements are capitalized and maintenance and repairs are expensed when incurred. Refer to Note 5 – Land, Buildings, Equipment and Software, Net for further discussion.
Software - Internal Use and Product	Software - Internal Use and Product Internal Use: We capitalize direct costs associated with developing, purchasing or otherwise acquiring software for internal use and amortize these costs on a straight-line basis over the expected useful life of the software, beginning when the software is implemented (Internal Use Software). Costs incurred for upgrades and enhancements that will not result in additional functionality are expensed as incurred. Amounts expended for Internal Use Software are included in Cash Flows from Investing. Product: We also capitalize certain costs related to the development of software solutions to be sold to our customers upon reaching technological feasibility (Product Software). These costs are amortized on a straight-line basis over the estimated economic life of the software. Amounts expended for Product Software are included in Cash Flows from Operations. We perform periodic reviews to ensure that unamortized Product Software costs remain recoverable from estimated future operating profits (net realizable value or NRV). Costs to support or service licensed software are charged to Costs of outsourcing as incurred.

Costs to support or service licensed software are charged to Costs of outsourcing as incurred.
Goodwill and Other Intangible Assets	Goodwill For acquired businesses, the Company records the acquired assets and assumed liabilities based on their relative fair values at the date of acquisitions (commonly referred to as the purchase price allocation). Goodwill represents the excess of the purchase price paid in excess of the fair value of net tangible and intangible assets acquired. For the Company’s business acquisitions, the purchase price is allocated to identifiable intangible assets separate from goodwill if they are from contractual or other legal rights, or if they could be separated from the acquired business and sold, transferred, licensed, rented or exchanged. We test goodwill for impairment annually or more frequent if an event or change in circumstances indicate the asset may be impaired. Impairment testing for goodwill is done at the reporting unit level. We determined the fair value of our reporting units utilizing a combination of both an Income Approach and a Market Approach. The Income Approach utilizes a discounted cash flow analysis based upon the forecasted future business results of our reporting units. The Market Approach utilizes the guideline public company method. If the fair value of a reporting unit is less than its carrying amount, an impairment charge would be recognized for amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit. Refer to Note 6 – Goodwill and Intangible Assets, Net for further information. Other Intangible Assets Other intangible assets primarily consist of assets acquired through business combinations, including installed customer base and distribution network relationships, patents and trademarks. Other intangible assets are amortized on a straight-line basis over their estimated economic lives unless impairment is identified. Refer to Note 6 – Goodwill and Intangible Assets, Net for further information. Impairment of Long-Lived Assets We review the recoverability of our long-lived assets, including buildings, equipment, internal use software, product software and other intangible assets, when events or changes in circumstances occur that indicate that the carrying value of the asset may not be recoverable. The assessment of possible impairment is based on our ability to recover the carrying value of the asset from the expected future pre-tax cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset, an impairment loss is recognized for the difference between estimated fair value and carrying value. Our primary measure of fair value is based on forecasted cash flows.
Pension and Post-Retirement Benefit Obligations	Pension Obligations We sponsor various forms of defined benefit pension plans in several countries covering employees who meet eligibility requirements. Several statistical and other factors that attempt to anticipate future events are used in calculating the expense, liability and asset values related to our pension plans. These factors include assumptions we make about the discount rate, expected return on plan assets, the rate of future compensation increases and mortality rates. The discount rate is used to present value our future anticipated benefit obligations. The discount rate reflects the current rate at which benefit liabilities could be effectively settled considering the timing of expected payments for plan participants. In estimating our discount rate, we consider rates of return on high-quality fixed-income investments adjusted to eliminate the effects of call provisions, as well as the expected timing of pension and other benefit payments. The expected rate of return on plan assets is the long-term rate of return we expect to earn on plan assets. When estimating the expected rate of return, in addition to assessing recent performance, we consider the historical returns earned on plan assets, the rates of return expected in the future, and our investment strategy and asset mix with respect to the plans’ funds. The expected rate of return on plan assets is reviewed annually and revised, as necessary, to reflect changes in financial markets and our investment strategy. Each year, the difference between the actual return on plan assets and the expected return on plan assets, as well as increases or decreases in the benefit obligation as a result of changes in the discount rate and other actuarial assumptions, are added to or subtracted from any cumulative actuarial gain or loss from prior years. This amount is the net actuarial gain or loss recognized in Accumulated other comprehensive loss. We amortize net actuarial gains and losses as a component of net pension cost for a year if, as of the beginning of the year, that net gain or loss (excluding asset gains or losses that have not been recognized in market-related value) exceeds 10% of the greater of the projected benefit obligation or the market-related value of plan assets (the "corridor" method). This determination is made on a plan-by-plan basis. If amortization is required for a particular plan, we amortize the applicable net gain or loss in excess of the 10% threshold on a straight-line basis in net periodic pension cost over the remaining service period of the employees participating in that pension plan. In plans where substantially all participants are inactive, the amortization period for the excess is the average remaining life expectancy of the plan participants.
Income Tax, Policy	Income Taxes We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are based on differences between U.S. GAAP reporting and tax bases of assets or liabilities and based on current tax laws, regulations and rates. The recognition of deferred tax assets requires an assessment to determine the realization of such assets. Management establishes valuation allowances on deferred tax assets when it is determined “more-likely-than-not” that some portion or all of the deferred tax assets may not be realized. Management considers positive and negative evidence in evaluating the ability of the Company to realize its deferred tax assets, including its historical results and forecasts of future ability to realize its deferred tax assets, including projected future taxable income, the expected timing of the reversals of existing temporary differences and tax planning strategies. We are subject to ongoing tax examinations and assessments in various jurisdictions. We have unrecognized tax benefits for uncertain tax positions. We follow U.S. GAAP which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Our ongoing assessments of the more-likely-than-not outcomes of the examinations and related tax positions require judgment and can materially increase or decrease our effective tax rate, as well as impact our operating results.
Foreign Currency Transactions and Re-measurement	Foreign Currency Translation and Re-measurement The functional currency for most foreign operations is the local currency. Net assets are translated at current rates of exchange and income, expense and cash flow items are translated at average exchange rates for the applicable period. The translation adjustments are recorded in Accumulated other comprehensive loss. The U.S. Dollar is used as the functional currency for certain foreign subsidiaries that conduct their business in U.S. Dollars. A combination of current and historical exchange rates is used in re-measuring the local currency transactions of these subsidiaries and the resulting exchange adjustments are recorded in Currency (gains) and losses within other expenses, net together with other foreign currency re-measurements.
