Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements of Diebold Nixdorf, Incorporated and its subsidiaries (collectively, the Company) have been prepared in accordance with the instructions to Form 10-Q and therefore do not include all information and footnotes necessary for a fair presentation of financial position, results of operations and cash flows in conformity with accounting principles generally accepted in the United States (U.S. GAAP) ; however, such information reflects all adjustments (consisting solely of normal recurring adjustments) that are, in the opinion of management, necessary for a fair statement of the results for the interim periods. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes contained in the Company’s annual report on Form 10-K for the year ended December 31, 2017 . In addition, some of the Company’s statements in this quarterly report on Form 10-Q may involve risks and uncertainties that could significantly impact expected future results. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of results to be expected for the full year. In connection with recent changes in the Company's leadership, beginning with the second quarter of 2018, the Company's reportable operating segments are be based on the following solutions: Eurasia Banking, Americas Banking and Retail. As a result, the Company reclassified comparative periods for consistency. The Company has reclassified the presentation of certain prior-year information to conform to the current presentation. The Company included finance lease receivables of $12.8 and $14.4 in other assets as of June 30, 2018 and December 31, 2017 , respectively, in the condensed consolidated balance sheets. Recently Adopted Accounting Guidance Standards Adopted Description Effective Date Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers The standard replaced the most recent previously existing revenue recognition guidance in U.S. GAAP and required additional financial statement disclosures. The standard requires revenue to be recognized when the Company expects to be entitled in exchange for the transfer of promised goods or services to customers. The standard was adopted using a modified retrospective approach to open contracts as of the effective date, January 1, 2018. The standard is intended to reduce potential for diversity in practice at initial application and reducing the cost and complexity of applying Topic 606 both at transition and prospectively. As a result of the adoption, the cumulative increase to the Company's retained earnings at January 1, 2018 was $4.6. January 1, 2018 ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost The standard was issued to address the net presentation of the components of net benefit cost. The standard requires that service cost be presented in the same line item as other current employee compensation costs and that the remaining components of net benefit cost be presented in a separate line item outside of any subtotal for income from operations. The adoption of this update did not have a material impact on the financial statements of the Company. January 1, 2018 ASU 2017-12, Derivatives and Hedging: Target Improvements to Accounting for Hedging Activities The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. For existing hedges as of the date of the adoption, the Company eliminated a minimal amount of ineffectiveness by means of a cumulative-effect adjustment to accumulated other comprehensive income (AOCI) with a corresponding adjustment to retained earnings. As a result of the standard, $0.2 and $2.8 was included in net sales for the three and six months ended June 30, 2018, respectively, and $0.1 in cost of sales for the six months ended June 30, 2018. Early adopted January 1, 2018 ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The standard allows for reclassification of stranded tax effects on items resulting from the Tax Cuts and Jobs Act (the Tax Act) from AOCI to retained earnings. Tax effects unrelated to the Tax Act are released from AOCI using either the specific identification approach or the portfolio approach based on the nature of the underlying item. As a result of the adoption, during the first quarter of 2018, the Company recorded an adjustment to retained earnings resulting in a increase of $29.0, with a corresponding decrease to AOCI due to the reduction in the corporate tax rate. Early adopted January 1, 2018 ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment The standard simplifies the measurement of goodwill by eliminating step 2 from the goodwill impairment test. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The adoption of this update did not have an impact on the financial statements of the Company and only simplifies the procedure for the goodwill impairment test. Early adopted January 1, 2018 Recently Issued Accounting Guidance Standards Pending Adoption Description Effective/Adoption Date Anticipated Impact ASU 2016-02, Leases The standard requires that a lessee recognize on its balance sheet right-of-use assets and corresponding liabilities resulting from leasing transactions, as well as additional financial statement disclosures. Currently, U.S. GAAP only requires balance sheet recognition for leases classified as capital leases. The provisions of this update apply to substantially all leased assets. January 1, 2019 The Company is currently evaluating the impact the standard will have on its financial information and related disclosures. The standard requires a modified retrospective transition method with the option to elect a package of practical expedients, which the Company anticipates utilizing and will continue to evaluate. The Company anticipates a material balance sheet gross-up for the right-of-use assets and corresponding liabilities, with no anticipated impact to debt covenants. ASU 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs pursuant to SEC Staff Accounting Bulleting No. 118 This guidance amends SEC paragraphs in Topic 740, Income Taxes , to reflect SAB 118, which provides guidance for companies that are not able to complete their accounting for the income tax effects of the Tax Act in the period of enactment. January 1, 2021 This guidance also includes amendments to the XBRL Taxonomy. For public business entities, the amendments in ASU 2018-05 are effective for fiscal years ending after December 15, 2020 and early adoption is permitted. The Company does not expect adoption of this guidance to have a significant impact on its condensed consolidated financial statements.

Revenue from Contract with Cust

Revenue from Contract with Customer	6 Months Ended
	Jun. 30, 2018
Revenue Recognition [Abstract]
Revenue from Contract with Customer [Text Block]	Note 2: Revenue Revenue is measured based on consideration specified in a contract with a customer and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The Company's payment terms vary depending on the individual contracts and are generally fixed fee. The Company recognizes advance payments and billings in excess of revenue recognized as deferred revenue. In certain contracts where services are provided prior to billing, the Company recognizes a contract asset within trade receivables and other current assets. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. The Company recognizes shipping and handling fees billed when products are shipped or delivered to a customer and includes such amounts in net sales. Although infrequent, shipping and handling associated with outbound freight after control over a product has transferred to a customer is not a separate performance obligation, rather is accounted for as a fulfillment cost. Third-party freight payments are recorded in cost of sales. The Company includes a warranty in connection with certain contracts with customers, which are not considered to be separate performance obligations. The Company provides its customers a manufacturer’s warranty and records, at the time of the sale, a corresponding estimated liability for potential warranty costs. For additional information on product warranty refer to note 9. The Company also has extended warranty and service contracts available for its customers, which are recognized as separate performance obligations. Revenue is recognized on these contracts ratably as the Company has a stand-ready obligation to provide services when or as needed by the customer. This input method is the most accurate assessment of progress toward completion the Company can apply. Nature of goods and services The following is a description of principal solutions offered within the Company's two main industry segments that generate the Company's revenue. For more detailed information about reportable operating segments, see note 20. The Company provides its banking customers product-related services which include proactive monitoring and rapid resolution of incidents through remote service capabilities or an on-site visit. First and second line maintenance, preventive maintenance and on-demand services keep the distributed assets of the Company's customers up and running through a standardized incident management process. Managed services and outsourcing consists of the end-to-end business processes, solution management, upgrades and transaction processing. The Company also provides a full array of cash management services, which optimizes the availability and cost of physical currency across the enterprise through efficient forecasting, inventory and replenishment processes. Banking and retail services may be sold separately or in bundled packages. The typical contract length for service is generally one year and is billed and paid in advance except for installations, among others. The Company's hardware-agnostic software applications facilitate millions of transactions via automated teller machines (ATMs), point of sale (POS) terminals, kiosks, and other self-service devices. The Company provides its banking customers front-end applications for consumer connection points and back-end platforms that manage channel transactions, operations and integration. For retail customers, the Company provides a comprehensive, modular solution capable of enabling the most advanced omnichannel retail use cases. The Company's platform software is installed within bank and retail data centers to facilitate omnichannel transactions, endpoint monitoring, remote asset management, customer marketing, merchandise management and analytics. These offerings include highly configurable, application program interface (API) enabled software that automates legacy banking transactions across channels. The Company’s software solution includes its professional services team, who provides systems integration, customization, consulting and project management. The Company’s advisory services team collaborates with its customers to help define optimal user experience, improve business processes, refine existing staffing models and deploy technology to meet branch and store automation objectives. Software licenses and professional services may be sold separately or in bundled packages. Software licenses when bundled with professional services, where the service is modifying the intellectual property (IP), is non-distinct from the professional service. The consideration (including any discounts) is allocated between distinct obligations in a bundle based on their stand-alone selling prices. For items that are not sold separately, the Company estimates stand-alone selling prices using the cost plus expected margin approach or in the case of the software license the residual approach may be used. The Company’s software licenses are functional in nature (the IP has significant stand-alone functionality); as such, the revenue recognition of distinct software license sales is at the point in time that the customer obtains control of the rights granted by the license. Revenue from professional services are recognized over time, because the customer simultaneously receives and consumes the benefits of the Company’s performance as the services are performed or when the Company’s performance creates an asset with no alternative use to the Company and the Company has an enforceable right to payment for performance completed to date. Generally revenue will be recognized using an input measure, typically costs incurred. Products for banking customers consists of cash recyclers and dispensers, intelligent deposit terminals, teller automation tools and kiosk technologies, as well as physical security solutions. The retail product portfolio includes modular, integrated and mobile POS and self-checkout (SCO) terminals that meet evolving automation and omnichannel requirements of consumers. Supplementing the POS system is a broad range of peripherals, including printers, scales and mobile scanners, as well as the cash management portfolio which offers a wide range of banknote and coin processing systems. Also in the portfolio, the Company provides self-checkout terminals and ordering kiosks which facilitate an efficient and user-friendly purchasing experience. The Company’s hybrid product line can alternate from an attended operator to self-checkout with the press of a button as traffic conditions warrant throughout the business day. For bundled packages, the Company accounts for individual services separately if they are distinct. A distinct service is separately identifiable from other items in the bundled package if a customer can benefit from it on its own or with other resources that are readily available to the customer. The consideration (including any discounts) is allocated between separate services or distinct obligations in a bundle based on their stand-alone selling prices. The stand-alone selling prices are determined based on the prices at which the Company separately sells the products or services. For items that are not sold separately, the Company estimates stand-alone selling prices using the cost plus expected margin approach. Revenue on service contracts is recognized ratably over time, generally using an input measure, as the customer simultaneously receives and consumes the benefits of the Company’s performance as the services are performed. In some circumstances, when global service supply chain services are not included in a term contract and rather billed as they occur, revenue on these billed work services are recognized at a point in time as transfer of control occurs. Product revenue is recognized at the point in time that the customer obtains control of the product, which could be upon delivery or upon completion of installation services, depending on contract terms. Disaggregation of revenue For additional information related to revenue disaggregation by reportable segment, refer to note 20.

The amount of revenue recognized in 2018 from performance obligations satisfied (or partially satisfied) in previous periods, mainly due to the changes in the estimate of variable consideration and contract modifications was de minimis. There have been $2.1 and $5.0 during the three months ended June 30, 2018 and 2017, respectively, and $10.9 and $14.8 during the six months ended June 30, 2018 and 2017, respectively, of impairment losses recognized as bad debt related to receivables or contract assets arising from the Company's contracts with customers. As of January 1, 2018, the Company had $437.5 of unrecognized deferred revenue constituting the remaining performance obligations that are either unsatisfied (or partially unsatisfied). In 2018, the Company recognized revenue of $179.7 related to the Company's deferred revenue balance at January 1, 2018. Contract assets are the rights to consideration in exchange for goods or services that the Company has transferred to a customer when that right is conditional on something other than the passage of time. Contract assets of the Company primarily relate to the Company's rights to consideration for goods shipped and services provided but not contractually billable at the reporting date. The contract assets are reclassified into the receivables balance when the rights to receive payment become unconditional. Contract liabilities are recorded for any services billed to customers and not yet recognizable if the contract period has commenced or for the amount collected from customers in advance of the contract period commencing. In addition, contract liabilities are recorded as advanced payments for products and other deliverables that are billed to and collected from customers prior to revenue being recognizable. Transaction price and variable consideration The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer, excluding amounts collected on behalf of third parties. This consideration can include fixed and variable amounts and is determined at contract inception and updated each reporting period for any changes in circumstances. The transaction price also considers variable consideration, time value of money and the measurement of any non-cash consideration, all of which are estimated at contract inception and updated at each reporting date for any changes in circumstances. The Company also applies the ‘as invoiced’ practical expedient in paragraph 606-10-55-18 related to performance obligations satisfied over time, which permits the Company to recognize revenue in the amount to which it has a right to invoice the customer if that amount corresponds directly with the value to the customer of the Company’s performance completed to date. Transaction price allocated to the remaining performance obligations As of June 30, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $2,600 . The Company expects to recognize revenue on the remaining performance obligations over the next twelve months. The Company enters into service agreements with cancellable terms after a certain period without penalty. Unsatisfied obligations reflect only the obligation during the initial term. The Company applies the practical expedient in paragraph 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one year or less. The Company also applies the ‘as invoiced’ practical expedient in paragraph 606-10-55-18 related to performance obligations satisfied over time which permits the Company to recognize revenue in the amount to which it has a right to invoice the customer if that amount corresponds directly with the value to the customer of the Company’s performance completed to date. Cost to obtain and cost to fulfill a contract The Company has minimal cost to obtain or fulfill contracts for customers for the periods presented. The Company pays commissions to the sales force based on multiple factors including but not limited to order entry, revenue recognition and portfolio growth. These incremental commission fees paid to the sales force meet the criteria to be considered a cost to obtain a contract, as they are directly attributable to a contract, incremental and management expects the fees are recoverable. The Company applies the practical expedient and recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. The costs that are not capitalized are included in cost of sales. The costs related to contracts with greater than a one-year term are immaterial and continue to be recognized in cost of sales. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of sales. The Company has minimal cost for shipping and handling costs for the periods presented. Changes in accounting policies Except for the changes below, the Company has consistently applied the accounting policies to all periods presented in these condensed consolidated financial statements. The Company adopted Topic 606, Revenue from Contracts with Customers , with a date of initial application of January 1, 2018. As a result, the Company has changed its accounting policy for revenue recognition as detailed below. The Company applied Topic 606 using the cumulative effect method - i.e., by recognizing the cumulative effect of initially applying Topic 606 as an adjustment to the opening balance of equity at January 1, 2018. Therefore, the comparative information has not been adjusted and continues to be reported under Topic 605. The Company applied the practical expedient related to assessment of contract modifications, whereby the Company is essentially allowed to use hindsight when assessing the effect of a modification and accounting for the modified contract as if it existed from the beginning of the original contract. The details of the significant changes and quantitative impact of the changes are set out below. Professional service contracts Previously, the Company recognized revenue for professional services contracts either on a milestone method or completed contract basis. Under Topic 606, the Company recognizes revenue when control transfers to a customer. As professional services can be highly customized for each customer, there is no alternative use for the services. When there is an enforceable right to payment for service completed combined with no alternative use of the services, the services meet criteria for over time revenue recognition. Revenue is recognized as the services are provided and as the customer benefits from the service. Revenue is recognized progressively based on the costs incurred method. When the professional services are not highly customized as in basic software installation services, customers do not take control of the services until they are completed. Therefore, the Company continues to recognize revenue for such contracts when the services are completed and customers formally accept them. Impacts on financial statements The following tables summarize the impacts of adopting Topic 606 on the Company’s condensed consolidated financial statements as of and for the period ended June 30, 2018 as if the Company continued to follow its accounting policies under the previous revenue recognition guidance. Impact of changes in accounting policy for the six months ended June 30, 2018 (unaudited) As Reported Adjustments Balances without adoption of Topic 606 Trade receivables, less allowances for doubtful accounts of $60.6 and $71.7, respectively $ 809.3 $ (6.8 ) $ 802.5 Inventories $ 820.9 $ 18.8 $ 839.7 Deferred revenue $ 416.1 $ 23.6 $ 439.7 Deferred income taxes $ 255.4 $ (2.8 ) $ 252.6 Retained earnings $ 215.8 $ (8.8 ) $ 207.0 The impact to net sales and cost of sales would have been decreases of $14.7 and $8.2 , respectively, for the three months ended June 30, 2018 and $13.8 and $8.6 , respectively, for the six months ended June 30, 2018. The impact after tax was $(4.6) and $(3.6) for the three and six months ended June 30, 2018, respectively, and was primarily a result of timing of deferred revenue related to products and software for certain amounts being recognized that would have previously been deferred, and certain amounts being deferred that would have previously been recognized.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	Earnings (Loss) Per Share Basic earnings (loss) per share is based on the weighted-average number of common shares outstanding. Diluted earnings (loss) per share includes the dilutive effect of potential common shares outstanding. Under the two-class method of computing earnings (loss) per share, non-vested share-based payment awards that contain rights to receive non-forfeitable dividends are considered participating securities. The Company’s participating securities include restricted stock units (RSUs) , director deferred shares and shares that were vested but deferred by employees. The Company calculated basic and diluted earnings (loss) per share under both the treasury stock method and the two-class method. For the three and six months ended June 30, 2018 and 2017, there were no differences in the earnings (loss) per share amounts calculated under the two methods. Accordingly, the treasury stock method is disclosed below. The following table represents amounts used in computing earnings (loss) per share and the effect on the weighted-average number of shares of dilutive potential common shares: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Numerator Income (loss) used in basic and diluted earnings (loss) per share Net income (loss) $ (133.4 ) $ (23.6 ) $ (196.7 ) $ (75.8 ) Net income attributable to noncontrolling interests 5.1 7.0 12.7 13.6 Net income (loss) attributable to Diebold Nixdorf, Incorporated $ (138.5 ) $ (30.6 ) $ (209.4 ) $ (89.4 ) Denominator Weighted-average number of common shares used in basic earnings (loss) per share 76.0 75.5 75.9 75.4 Weighted-average number of shares used in diluted earnings (loss) per share (1) 76.0 75.5 75.9 75.4 Net income (loss) attributable to Diebold Nixdorf, Incorporated Basic earnings (loss) per share $ (1.82 ) $ (0.41 ) $ (2.76 ) $ (1.19 ) Diluted earnings (loss) per share $ (1.82 ) $ (0.41 ) $ (2.76 ) $ (1.19 ) Anti-dilutive shares Anti-dilutive shares not used in calculating diluted weighted-average shares 5.0 2.9 4.4 2.6 (1) Incremental shares of 0.7 and 1.0 shares for the three months ended June 30, 2018 and 2017 , respectively, and 0.8 and 0.9 shares for the six months ended June 30, 2018 and 2017 , respectively, would have been included in the weighted-average number of shares used in diluted earnings (loss) per share used in the computation of diluted earnings (loss) per share because their effects are dilutive. In May 2018, the Company announced its decision to reallocate future dividend funds towards debt reduction and other capital resource needs.

SHARE-BASED COMPENSATION	Share-Based Compensation The Company’s share-based compensation payments to employees are recognized based on their grant-date fair values during the period in which the employee is required to provide services in exchange for the award. Share-based compensation is primarily recognized as a component of selling and administrative expense. Total share-based compensation expense was $6.6 and $8.2 for the three months ended June 30, 2018 and 2017 , respectively, and was $20.3 and $15.0 for the six months ended June 30, 2018 and 2017 , respectively. Options outstanding and exercisable as of June 30, 2018 are included under the Company’s 1991 Equity and Performance Incentive Plan (as Amended and Restated as of February 12, 2014) (the 1991 Plan) and the Company's 2017 Equity and Performance Incentive Plan (the 2017 Plan). In conjunction with the appointment of the Chief Executive Officer on February 21, 2018, the board approved the grant of options, performance share units and RSUs outside of the the 2017 Plan. Changes during the six months ended June 30, 2018 were as follows: Number of Weighted- Weighted- Aggregate (1) (per share) (in years) Outstanding at January 1, 2018 2.3 $ 29.68 Granted 0.5 $ 17.54 Outstanding at June 30, 2018 2.8 $ 27.28 7 $ — Options exercisable at June 30, 2018 1.6 $ 30.51 6 $ — Options vested and expected to vest (2) at June 30, 2018 2.7 $ 27.46 7 $ — (1) The aggregate intrinsic value (the difference between the closing price of the Company’s common shares on the last trading day of the second quarter of 2018 and the exercise price, multiplied by the number of “in-the-money” options) that would have been received by the option holders had all option holders exercised their options on June 30, 2018 . The amount of aggregate intrinsic value will change based on the fair market value of the Company’s common shares. (2) The options expected to vest are the result of applying the pre-vesting forfeiture rate assumption to total outstanding non-vested options. The following table summarizes information on non-vested RSUs and performance shares relating to employees and non-employee directors for the six months ended June 30, 2018 : Number of Weighted-Average RSUs: Non-vested at January 1, 2018 1.3 $ 27.76 Forfeited (0.1 ) $ 22.38 Vested (0.7 ) $ 28.49 Granted 1.3 $ 17.82 Non-vested at June 30, 2018 1.8 $ 20.59 Performance Shares: Non-vested at January 1, 2018 2.5 $ 31.37 Forfeited (0.6 ) $ 29.68 Vested (0.2 ) $ 32.38 Granted 1.6 $ 22.64 Non-vested at June 30, 2018 3.3 $ 26.93 Performance shares are granted to employees and vest based on the achievement of certain performance objectives, as determined by the board of directors each year. Each performance share earned entitles the holder to one common share of the Company. The Company's performance shares include performance objectives that are assessed after a three-year period as well as performance objectives that are assessed annually over a three-year period. No shares are vested unless certain performance threshold objectives are met. As of June 30, 2018 , there were 0.1 non-employee director deferred shares vested and outstanding. On April 25, 2018, the Company's shareholders approved amendments to the 2017 Plan, which provide for an additional 1.2 common shares available for award. The 2017 Plan is expected to attract and retain directors, officers and employees of the Company by providing incentives and rewards for performance.

Income Tax Disclosure [Abstract]
INCOME TAXES	Income Taxes The effective tax rate on loss from continuing operations was 18.2 percent for the three months ended June 30, 2018 and 4.9 percent for the six months ended June 30, 2018. The benefit on the losses for these periods was decreased primarily due to nondeductible permanent discrete adjustment associated with the $90.0 of goodwill impairment charge and the impacts of the Tax Act, more specifically, impacts related to the global intangible low-taxed income (GILTI) on the estimated annual tax rate. The effective tax rate could vary in future periods based on the Company’s earnings before taxes and clarifications around the Tax Act. The effective tax rate on loss from continuing operations was 60.6 percent for the three months ended June 30, 2017 and 43.7 percent for the six months ended June 30, 2017. The tax rate on the loss for the three and six months ended June 30, 2017 was increased due to the jurisdictional income (loss) mix and varying statutory rates in the Company’s global footprint. These increases to the overall tax rate for these periods was offset in part by additional discrete expense items recognized in the quarter related to uncertain tax positions.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER ASSETS	Goodwill and Other Assets As of June 30, 2018, the Company’s three reportable operating segments are Eurasia Banking, Americas Banking and Retail. The Company has allocated goodwill to its Eurasia Banking, Americas Banking and Retail reportable operating segments. The changes in carrying amounts of goodwill within the Company's segments are summarized as follows: Eurasia Banking Americas Banking Retail Total Goodwill $ 513.0 $ 425.4 $ 350.6 $ 1,289.0 Accumulated impairment losses (168.7 ) (122.0 ) — (290.7 ) Balance at January 1, 2017 $ 344.3 $ 303.4 $ 350.6 $ 998.3 Goodwill acquired 1.6 — 4.0 5.6 Goodwill adjustment (1.1 ) (1.0 ) (0.8 ) (2.9 ) Currency translation adjustment 71.8 2.2 42.1 116.1 Goodwill $ 585.3 $ 426.6 $ 395.9 $ 1,407.8 Accumulated impairment losses (168.7 ) (122.0 ) — (290.7 ) Balance at December 31, 2017 $ 416.6 $ 304.6 $ 395.9 $ 1,117.1 Currency translation adjustment (14.9 ) (4.5 ) (9.1 ) (28.5 ) Goodwill $ 570.4 $ 422.1 $ 386.8 $ 1,379.3 Impairment (53.5 ) — (36.5 ) (90.0 ) Accumulated impairment losses (222.2 ) (122.0 ) (36.5 ) (380.7 ) Balance at June 30, 2018 $ 348.2 $ 300.1 $ 350.3 $ 998.6 In 2018, the Company acquired the remaining portion of the noncontrolling interest in its China operations for $5.8 for which no goodwill was recorded. In 2017, the $5.6 acquired goodwill from Moxx Group B.V. (Moxx) and Visio Objekt GmbH (Visio) primarily relates to anticipated synergies achieved through increased scale and higher utilization of the service organization. The Company has identified four reporting units, which are Eurasia Banking, Americas Banking, Europe, Middle East and Africa (EMEA) Retail and Rest of World Retail. Management determined that the Eurasia Banking, Rest of World Retail and EMEA Retail reporting units had excess fair value of $64.2 or 5.2 percent , $20.5 or 18.8 percent and $134.6 or 21.4 percent , respectively, when compared to their carrying amounts. The Americas Banking reporting unit had excess fair value of greater than 80 percent cushion when compared to its carrying amount. Changes in certain assumptions or the Company's failure to execute on the current plan could have a significant impact to the estimated fair value of the reporting units. During the second quarter of 2018, the Company performed an impairment test of goodwill for all of its line of businesses (LoB) reporting units due to the change in its reportable operating segments. The Company estimated the fair value of its nine LoB reporting unit using a combination of the income valuation and market approach in valuation methodology. The determination of the fair value of the reporting unit requires significant estimates and assumptions, including significant unobservable inputs. The determination of the fair value of the reporting unit requires significant estimates and assumptions, including significant unobservable inputs. The key inputs included, but were not limited to, discount rates, terminal growth rates, market multiple data from selected guideline public companies, management’s internal forecasts which include numerous assumptions such as projected net sales, gross profit, sales mix, operating and capital expenditures and earnings before interest and taxes margins, among others. Based on the results of the LoB testing, the fair values of each of the Company's reporting units exceed their carrying values except for the Services-Asia Pacific (AP) and Software-EMEA reporting units. Therefore, the Company recognized a non-cash goodwill impairment loss of $90.0 during the second quarter of 2018. In 2017, the Company recorded impairments totaling $3.1 related to information technology (IT) transformation and integration activities.

DN2020 Plan During 2016, the Company launched a multi-year integration and transformation program, known as DN2020. The DN2020 plan focused on the utilization of cost efficiencies and synergy opportunities that result from the transformational acquisition of Wincor Nixdorf AG (Diebold Nixdorf AG), which aligned employee activities with the Company's goal of delivering cost reductions of approximately $240 by the year 2020. The Company incurred restructuring charges of $2.2 and $14.4 for the three months ended June 30, 2018 and 2017, respectively, and $6.0 and $27.3 for the six months ended June 30, 2018 and 2017, respectively, related to DN2020.

The Company has $400.0 aggregate principal amount of senior notes due 2024 (the 2024 Senior Notes), which are and will be guaranteed by certain of the Company’s existing and future domestic subsidiaries and mature in April 2024. On May 9, 2017, the Company entered into an incremental amendment to its Credit Agreement (the Incremental Agreement) which reduced the initial term loan B facility (the Term Loan B Facility) of a $1,000.0 U.S. dollar-denominated tranche to $475.0 . The reduction was funded using the $250.0 proceeds drawn from the Delayed Draw Term Loan A Facility, a replacement of $70.0 with Term Loan B Facility - Euro and previous principal payments. The interest rate with respect to the Term Loan B Facility - USD is based on, at the Company’s option, adjusted LIBOR plus 2.75 percent (with a floor of 0.00 percent) or Alternate Base Rate (ABR) plus 1.75 percent (with an ABR floor of 1.00 percent) and the interest rate with respect to the Term Loan B Facility - Euro is based on adjusted Euro Interbank Offered Rate (EURIBOR) plus 3.00 percent (with a floor of 0.00 percent). The Incremental Agreement also renewed the repricing premium of 1.00 percent in relation to the Term Loan B Facility, removed the requirement to prepay the Repriced Dollar Term Loan and the repriced Euro Term Loan upon any asset sale or casualty event if the Company is below a Total Net Leverage Ratio of 2.5 :1.0 on a pro forma basis for such asset sale or casualty event and provides additional restricted payments and investment carveouts in regards to certain assets acquired. All other material provisions under the Credit Agreement were unchanged. On April 17, 2018, the Company entered into an amendment to its Credit Agreement which modified its calculation of total net debt and its maximum allowable total net debt to the trailing twelve month's adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) leverage ratio (Leverage Ratio). The Credit Agreement financial covenant ratios at June 30, 2018 are as follows: • a maximum leverage ratio of 4.75 to 1.00 as of June 30, 2018 (reducing to 4.50 on December 31, 2018, and then further reduced to 4.25 on December 31, 2019); and • a minimum adjusted EBITDA to net interest expense coverage ratio (Coverage Ratio) of not less than 3.00 to 1.00 Below is a summary of financing and replacement facilities information: Financing and Replacement Facilities Interest Rate Index and Margin Maturity/Termination Dates Initial Term (Years) Credit Agreement facilities Revolving Facility LIBOR + 2.00% December 2020 5 Term Loan A Facility LIBOR + 2.00% December 2020 5 Delayed Draw Term Loan A Facility LIBOR + 2.00% December 2020 5 Term Loan B Facility - USD LIBOR (i) + 2.75% November 2023 7.5 Term Loan B Facility - Euro EURIBOR (ii) + 3.00% November 2023 7.5 2024 Senior Notes 8.5% April 2024 8 (i) LIBOR with a floor of 0.0% .

The debt facilities under the Credit Agreement are secured by substantially all assets of the Company and its domestic subsidiaries that are borrowers or guarantors under the Credit Agreement, subject to certain exceptions and permitted liens. The Company's financing agreements contain various financial covenants, including net debt to capitalization, net debt to EBITDA and net interest coverage ratio. As of June 30, 2018 , the Company was in compliance with the financial and other covenants in its debt agreements. However, the Company’s current operating performance has been below expectations that existed at the time that the financial covenant levels were established, and if financial performance does not improve, we anticipate noncompliance with the net debt to EBITDA financial covenant at the end of the third quarter of 2018. The Company is in process of seeking an amendment to that covenant or obtaining a waiver thereof from our lenders. There can be no assurance that the Company will be successful in obtaining an amendment or waiver on commercially reasonable terms or at all.

Noncontrolling Interest Disclosure [Text Block]	Redeemable Noncontrolling Interests Changes in the Company's redeemable noncontrolling interests balance are illustrated in the following table: 2018 2017 Balance at January 1 $ 492.1 $ 44.1 Other comprehensive income (12.1 ) (18.6 ) Redemption value adjustment (8.1 ) 39.4 Redemption of shares (3.3 ) (2.6 ) Reclassification of noncontrolling interest — 386.7 Balance at June 30 $ 468.6 $ 449.0 The Domination and Profit and Loss Transfer Agreement between Diebold Holding Germany Inc. & Co. KGaA (Diebold KGaA), a wholly-owned subsidiary of the Company, and Diebold Nixdorf AG (the DPLTA) became effective by entry in the commercial register at the local court of Paderborn (Germany) on February 14, 2017, at which time, the carrying value of the noncontrolling interest related to the Diebold Nixdorf AG ordinary shares the Company did not acquire of $386.7 and was reclassified to redeemable noncontrolling interest during the first quarter of 2017. For the period of time that the DPLTA is effective, the noncontrolling interest related to the Diebold Nixdorf AG ordinary shares the Company did not acquire will remain in redeemable noncontrolling interest and presented outside of equity in the condensed consolidated balance sheets of the Company. As of June 30, 2018 and December 31, 2017 , the balance related to the redeemable noncontrolling interest related to the Diebold Nixdorf AG ordinary shares the Company did not acquire was $439.2 and $454.6 , respectively. The change in the balance is related to the euro weakening. The DPLTA offers the Diebold Nixdorf AG minority shareholders, at their election, (i) the ability to put their Diebold Nixdorf AG ordinary shares to Diebold KGaA in exchange for cash compensation of €55.02 per Diebold Nixdorf AG ordinary share or (ii) to remain Diebold Nixdorf AG minority shareholders and receive a recurring compensation in cash of €2.82 per Diebold Nixdorf AG ordinary share for each full fiscal year of Diebold Nixdorf AG. The redemption value adjustment includes the updated cash compensation pursuant to the DPLTA. In early August 2018, Diebold Nixdorf AG shareholders have requested redemption of approximately 2.4 shares with a value of $160 . The Company expects to utilize cash on hand and borrowings under its Revolving Facility to fund the obligations. The ultimate timing and amount of any future cash payments related to the DPLTA are uncertain. The remaining balance relates to certain noncontrolling interests with redemption features, that include put rights that are not within the control of the issuer, which are considered redeemable noncontrolling interests. The redeemable noncontrolling interests were recorded at fair value as by applying the income approach using unobservable inputs for projected cash flows, including but not limited, to net sales and operating profit, and a discount rate, which are considered Level 3 inputs. The results of operations for these redeemable noncontrolling interests were not significant. The ultimate amount and timing of any future cash payments related to the put rights are uncertain.

Retirement Benefits [Abstract]
BENEFIT PLANS	Benefit Plans The Company has qualified retirement plans covering certain U.S. employees that have been closed to new participants since 2003 and frozen since December 2013. Plans that cover salaried employees provide retirement benefits based on an employee’s compensation during the ten years before the date of the plan freeze or the date of the employee's actual separation from service, if earlier. The Company’s funding policy for salaried plans is to contribute annually based on actuarial projections and applicable regulations. Plans covering hourly employees generally provide benefits of stated amounts for each year of service. The Company’s funding policy for hourly plans is to make at least the minimum annual contributions required by applicable regulations. The Company has non-qualified pension plans to provide supplemental retirement benefits to certain officers, which were also frozen since December 2013. Benefits are payable at retirement based upon a percentage of the participant’s compensation, as defined. In addition to providing retirement benefits, the Company provides post-retirement healthcare and life insurance benefits (referred to as other benefits) for certain retired employees. Retired eligible employees in the U.S. may be entitled to these benefits based upon years of service with the Company, age at retirement and collective bargaining agreements. There are no plan assets and the Company funds the benefits as the claims are paid. The post-retirement benefit obligation was determined by application of the terms of medical and life insurance plans together with relevant actuarial assumptions and healthcare cost trend rates. The Company also has defined benefit plans in Germany and Switzerland, among others. In Germany, post-employment benefit plans are set up as employer funded pension plans and deferred compensation plans. The employer funded pension commitments in Germany are based upon direct performance-related commitments in terms of defined contribution plans. Each beneficiary receives, depending on individual pay-scale grouping, contractual classification or income level, different yearly contributions. The contribution is multiplied by an age factor appropriate to the respective pension plan and credited to the individual retirement account of the employee. The retirement accounts may be used up at retirement by either a one-time lump-sum payout or payments of up to ten years. Insured events include disability, death and reaching of retirement age. In Switzerland, the post-employment benefit plan is required due to statutory provisions. The employees receive their pension payments as a function of contributions paid, a fixed interest rate and annuity factors. Insured events are disability, death and reaching of retirement age. The following table sets forth the net periodic benefit cost for the Company’s defined benefit pension plans and other benefits for the three months ended June 30 : Pension Benefits U.S.Plans Non-U.S. Plans Other Benefits 2018 2017 2018 2017 2018 2017 Components of net periodic benefit cost Service cost $ 0.9 $ 1.0 $ 2.8 $ 2.6 $ — $ — Interest cost 5.1 5.7 1.6 2.2 0.1 0.1 Expected return on plan assets (6.1 ) (6.5 ) (2.7 ) (2.1 ) — — Recognized net actuarial loss 1.7 1.5 (0.1 ) (0.1 ) — — Net periodic pension benefit cost $ 1.6 $ 1.7 $ 1.6 $ 2.6 $ 0.1 $ 0.1 The following table sets forth the net periodic benefit cost for the Company’s defined benefit pension plans and other benefits for the six months ended June 30 : Pension Benefits U.S.Plans Non-U.S. Plans Other Benefits 2018 2017 2018 2017 2018 2017 Components of net periodic benefit cost Service cost $ 1.9 $ 2.0 $ 5.6 $ 5.2 $ — $ — Interest cost 10.3 11.4 3.2 4.4 0.2 0.2 Expected return on plan assets (12.3 ) (13.0 ) (5.4 ) (4.2 ) — — Recognized net actuarial loss 3.3 3.0 (0.3 ) (0.2 ) — — Net periodic pension benefit cost $ 3.2 $ 3.4 $ 3.1 $ 5.2 $ 0.2 $ 0.2 Contributions There have been no significant changes to the expected 2018 plan year contribution amounts previously disclosed.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	Derivative Instruments and Hedging Activities The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate and foreign exchange rate risk, through the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business or financing activities. The Company’s derivative foreign currency instruments are used to manage differences in the amount of the Company’s known or expected cash receipts and cash payments principally related to the Company’s non functional currency assets and liabilities. The Company's interest rate derivatives are used to manage the differences in amount due to variable rate interest rate borrowings. The Company uses derivatives to mitigate the economic consequences associated with fluctuations in currencies and interest rates. The following table summarizes the gain (loss) recognized on derivative instruments: Derivative instrument Classification on condensed consolidated statements of operations Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Non-designated hedges and interest rate swaps Interest expense $ (0.8 ) $ (0.9 ) $ (1.1 ) $ (2.1 ) Foreign exchange forward contracts and cash flow hedges Net sales 0.2 — 2.8 — Foreign exchange forward contracts and cash flow hedges Cost of sales — — (0.1 ) — Foreign exchange forward contracts and cash flow hedges Foreign exchange gain (loss), net 0.3 4.2 0.5 4.0 Total $ (0.3 ) $ 3.3 $ 2.1 $ 1.9 As a result of the adoption of ASU 2017-12, $0.2 and $2.8 was included in net sales for the three and six months ended June 30, 2018, respectively and $0.1 in cost of sales for the six months ended June 30, 2018, which would have been included in foreign exchange gain (loss), net in the prior period. Foreign Exchange Net Investment Hedges The Company has international subsidiaries with net balance sheet positions that generate cumulative translation adjustments within AOCI. The Company uses derivatives to manage potential changes in value of its net investments. The Company uses the forward-to-forward method for its quarterly measurement of ineffectiveness assessments of hedge effectiveness. No ineffectiveness results if the notional amount of the derivative matches the portion of the net investment designated as being hedged because the Company uses derivative instruments with underlying exchange rates consistent with its functional currency and the functional currency of the hedged net investment. Changes in value that are deemed effective are accumulated in AOCI where they will remain until they are reclassified to income together with the gain or loss on the entire investment upon substantial liquidation of the subsidiary. The fair value of the Company’s net investment hedge contracts was $11.8 and $2.0 as of June 30, 2018 and December 31, 2017 , respectively. The net loss recognized in AOCI on net investment hedge derivative instruments was $11.8 and $1.5 in the three months ended June 30, 2018 and 2017 , respectively. The net loss recognized in AOCI on net investment hedge derivative instruments was $10.9 and $1.4 in the six months ended June 30, 2018 and 2017 , respectively. On August 15, 2016, the Company designated its €350.0 euro-denominated Term Loan B Facility as a net investment hedge of its investments in certain subsidiaries that use the euro as their functional currency in order to reduce volatility in stockholders' equity caused by the changes in foreign currency exchange rates of the euro with respect to the U.S. dollar. Effectiveness is assessed at least quarterly by confirming that the respective designated net investments' net equity balances at the beginning of any period collectively continues to equal or exceed the balance outstanding on the Company's euro-denominated term loan. Changes in value that are deemed effective are accumulated in AOCI. When the respective net investments are sold or substantially liquidated, the balance of the cumulative translation adjustment in AOCI will be reclassified into earnings. The net gain (loss) recognized in AOCI on net investment hedge foreign currency borrowings was $11.2 and $(19.6) for the three months ended June 30, 2018 and 2017 , respectively. The net gain (loss) recognized in AOCI on net investment hedge foreign currency borrowings was $5.4 and $(25.8) for the six months June 30, 2018 and 2017 , respectively. On March 30, 2017, the Company de-designated €130.6 of its euro-denominated Term Loan B Facility and on May 9, 2017, the Company designated an additional €66.8 of its euro-denominated Term Loan B Facility as a result of its repricing described under note 11 . On September 21, 2017, the Company de-designated €100.0 of its euro-denominated Term Loan B Facility. On June 21, 2018, the Company re-designated €30.2 of its euro-denominated Term Loan B Facility. Non-Designated Hedges A substantial portion of the Company’s operations and revenues are international. As a result, changes in foreign exchange rates can create substantial foreign exchange gains and losses from the revaluation of non-functional currency monetary assets and liabilities. The Company’s policy allows the use of foreign exchange forward contracts with maturities of up to 24 months to mitigate the impact of currency fluctuations on those foreign currency asset and liability balances. The Company elected not to apply hedge accounting to its foreign exchange forward contracts. Thus, spot-based gains/losses offset revaluation gains/losses within foreign exchange loss, net and forward-based gains/losses represent interest expense or income. The fair value of the Company’s non-designated foreign exchange forward contracts was $(2.4) and $(4.9) as of June 30, 2018 and December 31, 2017 , respectively. Cash Flow Hedges The Company is exposed to fluctuations in various foreign currencies against its functional currency. At the Company, both sales and purchases are transacted in foreign currencies. The Company has certain subsidiaries with the euro (EUR) as its functional currency that are primarily exposed to the U.S. dollar (USD) and Great Britain pound sterling (GBP). This risk is considerably reduced by natural hedging (i.e., management of sales and purchases by choice location and suppliers). For the remainder of the risk that is not naturally hedged, foreign currency forwards are used to manage the exposure between EUR-GBP and EUR-USD. Derivative transactions are recorded on the balance sheet at fair value. For transactions designated as cash flow hedges, the effective portion of changes in the fair value are recorded in AOCI and are subsequently reclassified into earnings in the period that the hedged forecasted transactions impact earnings within the same income statement line item as the earnings effect of the hedged transaction. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. As of June 30, 2018 , the Company had the following outstanding foreign currency derivatives that were used to hedge its foreign exchange risks: Foreign Currency Derivative Number of Instruments Notional Sold Notional Purchased Currency forward agreements (EUR-USD) 5 13.0 USD 11.1 EUR Currency forward agreements (EUR-GBP) 11 29.0 GBP 32.4 EUR Currency forward agreements (EUR-CZK) 3 182.6 CZK 7.1 EUR Interest Rate Cash Flow Hedges The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company has multiple pay-fixed receive-variable interest rate swaps outstanding with an aggregate notional amount of $400.0 . The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in AOCI and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. The fair value of the Company's interest rate contracts was $14.2 and $9.8 as of June 30, 2018 and December 31, 2017, respectively. Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. The Company estimates that a minimal amount will be reclassified as a decrease to interest expense over the next year. The Company has an interest rate swap for a nominal sum of €50.0 , which was entered into in May 2010 with a ten-year term from October 1, 2010 until September 30, 2020. This interest rate swap mitigated the interest rate risk associated with the European Investment Bank debt, which was paid in full during 2017. For this interest rate swap, the three-month EURIBOR is received and a fixed interest of 2.97 percent is paid. The fair value, which is measured at market prices, as of June 30, 2018 and December 31, 2017 was $(5.4) and $(5.5) , respectively. The interest rate contract is not designated and changes in the fair value of non-designated interest rate swap agreements are recognized in miscellaneous, net in the condensed consolidated statements of operations. The Company recognized $0.4 and $0.9 in interest expense relating to the interest rate swap for the three and six months ended June 30, 2018 , respectively. Additionally, the Company does not use derivatives for trading or speculative purposes and currently does not have any additional derivatives that are not designated as hedges.

During each of the six months ended June 30, 2018 and 2017, there were no transfers between levels. The carrying amount of the Company's debt instruments approximates fair value except for the 2024 Senior Notes. The fair value and carrying value of the 2024 Senior Notes are summarized as follows: June 30, 2018 December 31, 2017 Fair Value Carrying Fair Value Carrying 2024 Senior Notes 383.1 400.0 425.0 400.0 Refer to note 11 for further details surrounding the Company's long-term debt as of June 30, 2018 compared to December 31, 2017 . Additionally, the Company remeasures certain assets to fair value, using Level 3 measurements, as a result of the occurrence of triggering events. In the second quarter of 2018, in connection with the change in the Company's reportable operating segments which is considered a triggering event, the Company performed an impairment test of goodwill for all of its LoBs, see note 8 further details. Besides goodwill from certain reporting units noted above, there were no significant assets or liabilities that were remeasured at fair value on a non-recurring basis during the period presented.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	Commitments and Contingencies Contractual Obligation At June 30, 2018 , the Company had purchase commitments due within one year totaling $3.4 for materials and services through contract manufacturing agreements at negotiated prices. The Company guarantees a fixed cost of certain products used in production to its China strategic partners. Indirect Tax Contingencies The Company accrues non-income-tax liabilities for indirect tax matters when management believes that a loss is probable and the amounts can be reasonably estimated, while contingent gains are recognized only when realized. In the event any losses are sustained in excess of accruals, they are charged against income. In evaluating indirect tax matters, management takes into consideration factors such as historical experience with matters of similar nature, specific facts and circumstances, and the likelihood of prevailing. Management evaluates and updates accruals as matters progress over time. It is reasonably possible that some of the matters for which accruals have not been established could be decided unfavorably to the Company and could require recognizing future expenditures. Also, statutes of limitations could expire without the Company paying the taxes for matters for which accruals have been established, which could result in the recognition of future gains upon reversal of these accruals at that time. At June 30, 2018 , the Company was a party to several routine indirect tax claims from various taxing authorities globally that were incurred in the normal course of business, which neither individually nor in the aggregate are considered material by management in relation to the Company’s financial position or results of operations. In management’s opinion, the consolidated financial statements would not be materially affected by the outcome of these indirect tax claims and/or proceedings or asserted claims. In addition to these routine indirect tax matters, the Company was a party to the proceedings described below: In August 2012, one of the Company's Brazil subsidiaries was notified of a tax assessment of approximately R$270.0 , including penalties and interest, regarding certain Brazil federal indirect taxes (Industrialized Products Tax, Import Tax, Programa de Integração Social and Contribution to Social Security Financing) for 2008 and 2009. The assessment alleges improper importation of certain components into Brazil's free trade zone that would nullify certain indirect tax incentives. On September 10, 2012, the Company filed its administrative defenses with the tax authorities. In March 2017, the administrative proceedings concluded and the assessment was reduced approximately 95 percent to a total of R$17.3 including penalties and interest as of March 2017. The Company is pursuing its remedies in the judicial sphere and management continues to believe that it has valid legal positions. In addition, this matter could negatively impact Brazil federal indirect taxes in other years that remain open under statute. It is reasonably possible that the Company could be required to pay taxes, penalties and interest related to this matter, which could be material to the Company's consolidated financial statements. At June 30, 2018 and December 31, 2017 , the Company had accrual related to the Brazil indirect tax matter of $4.2 and $4.9 , respectively. The Company has challenged the customs rulings in Thailand seeking to retroactively collect customs duties on previous imports of ATMs. Management believes that the customs authority’s attempt to retroactively assess customs duties is in contravention of World Trade Organization agreements and, accordingly, challenged the rulings. In the third quarter of 2015, the Company received a prospective ruling from the U.S. Customs Border Protection which is consistent with the Company's interpretation of the treaty in question. In August 2017, the Supreme Court of Thailand ruled in the Company's favor, finding that Customs' attempt to collect duties for importation of ATMs is improper. In addition, in August 2016 and February 2017, the tax court of appeals rendered decisions in favor of the Company related to more than half of the assessments at issue. The surviving matters remain at various stages of the appeals process and the Company will use the Supreme Court's decision in support of its position in those matters. Management remains confident that the Company has a valid legal position in these appeals. Accordingly, the Company does not have any amount accrued for this contingency. A loss contingency is reasonably possible if it has a more than remote but less than probable chance of occurring. Although management believes the Company has valid defenses with respect to its indirect tax positions, it is reasonably possible that a loss could occur in excess of the estimated accrual. The Company estimated the aggregate risk at June 30, 2018 to be up to $128.1 for its material indirect tax matters, of which $22.0 and $27.0 , respectively, primarily relates to the Brazil indirect tax matter and Thailand customs matter disclosed above. The aggregate risk related to indirect taxes is adjusted as the applicable statutes of limitations expire. Legal Contingencies At June 30, 2018 , the Company was a party to several lawsuits that were incurred in the normal course of business, which neither individually nor in the aggregate are considered material by management in relation to the Company’s financial position or results of operations. In management’s opinion, the Company's consolidated financial statements would not be materially affected by the outcome of these legal proceedings, commitments or asserted claims. In addition to these normal course of business litigation matters, the Company was a party to the proceedings described below: Diebold KGaA is a party to appraisal proceedings (Spruchverfahren) relating to the DPLTA entered into by Diebold KGaA and Diebold Nixdorf AG on September 26, 2016 pending at the District Court (Landgericht) of Dortmund (Germany). The appraisal proceedings were filed by minority shareholders of Diebold Nixdorf AG challenging the adequacy of both, the cash exit compensation of €55.02 per Diebold Nixdorf AG share and the annual recurring compensation of €2.82 per Diebold Nixdorf AG share offered in connection with the DPLTA. A ruling by the court would apply to all Diebold Nixdorf AG shares outstanding at the time the DPLTA became effective. While the Company believes that the compensation offered in connection with the DPLTA was fair and the claims lack merit, this matter is still at a preliminary stage and the outcome is uncertain. As a result, the Company is unable to reasonably estimate the possible loss or range of losses, if any, arising from this litigation.

Segment Information

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	Segment Information The Company's accounting policies derive segment results that are the same as those the Chief Operating Decision Maker (CODM) regularly reviews and uses to make decisions, allocate resources and assess performance. The Company continually considers its operating structure and the information subject to regular review by its Chief Executive Officer, who is the CODM, to identify reportable operating segments. The Company’s operating structure is based on a number of factors that management uses to evaluate, view and run its business operations, which currently includes, but is not limited to, product, service and solution. The Company's previous reportable operating segments included the lines of business (LoB): Services, Systems, and Software. The Company began to reorganize its management team reporting to the CODM and assess its new operating model during the first half of 2018. The results of re-evaluating the LoB operating model highlighted the need to transform the Company’s operating model to Banking and Retail. The renewed focus on the customer experience has led the Company to reorganize its operating model. The LoBs will continue to develop solutions, but will operate as cost centers focused on designing and delivering innovative and customer-driven products. The realignment to Banking and Retail enables quicker decision making, reduces complexity, makes better use of talent and promotes the best possible experience for the Company’s customers. Beginning with the second quarter of 2018, the Company's reportable operating segments are based on the following solutions: Eurasia Banking, Americas Banking and Retail. As a result, the Company reclassified comparative periods for consistency. Segment revenue represents revenues from sales to external customers. Segment operating profit is defined as revenues less expenses identifiable to those segments. The Company does not allocate to its segments certain operating expenses, managed at the corporate level; that are not routinely used in the management of the segments; or information that is impractical to allocate. These unallocated costs include certain corporate costs, amortization of acquired intangible assets and deferred revenue, restructuring charges, impairment charges, legal, indemnification, and professional fees related to acquisition and divestiture expenses, along with other income (expenses). Segment operating profit reconciles to consolidated income (loss) before income taxes by deducting corporate costs and other income or expense items that are not attributed to the segments. Corporate charges not allocated to segments include headquarter-based costs associated with procurement, human resources, compensation and benefits, finance and accounting, global development/engineering, global strategy/mergers and acquisitions, global IT, tax, treasury and legal. Assets are not allocated to segments, and thus are not included in the assessment of segment performance, and consequently, we do not disclose total assets and depreciation and amortization expense by reportable operating segment. For additional information related to the Company's revenue sources, refer to note 2. In addition to the considerations mentioned above regarding the CODM, the Company has assessed several factors in disaggregating revenue which include the information disclosed in this report and other disaggregated revenue information provided in investor presentations and board of director presentations. The following tables represent information regarding the Company’s segment information and provides a reconciliation between segment operating profit and the consolidated income (loss) before income taxes: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Net sales summary by segment Eurasia Banking $ 437.5 $ 473.5 $ 872.6 $ 911.5 Americas Banking 370.6 370.4 704.3 752.0 Retail 297.5 290.0 592.9 573.2 Total revenue $ 1,105.6 $ 1,133.9 $ 2,169.8 $ 2,236.7 Intersegment revenue Eurasia Banking $ 31.7 $ 20.3 $ 53.0 $ 57.0 Americas Banking 3.5 8.8 9.0 17.3 Total intersegment revenue $ 35.2 $ 29.1 $ 62.0 $ 74.3 Segment operating profit Eurasia Banking $ 17.7 $ 29.9 $ 36.6 $ 51.0 Americas Banking (0.1 ) 10.1 7.6 35.5 Retail 6.2 26.3 17.3 44.0 Total segment operating profit 23.8 66.3 61.5 130.5 Corporate charges not allocated to segments (1) (17.9 ) (25.9 ) (37.4 ) (48.4 ) Restructuring charges (2.2 ) (14.4 ) (6.1 ) (27.3 ) Net non-routine expense (135.2 ) (56.1 ) (170.5 ) (133.5 ) (155.3 ) (96.4 ) (214.0 ) (209.2 ) Operating profit (loss) (131.5 ) (30.1 ) (152.5 ) (78.7 ) Other income (expense) (31.5 ) (29.8 ) (54.4 ) (56.0 ) Income (loss) before taxes $ (163.0 ) $ (59.9 ) $ (206.9 ) $ (134.7 ) (1) Corporate charges not allocated to segments include headquarter-based costs associated with procurement, human resources, compensation and benefits, finance and accounting, global development/engineering, global strategy/mergers and acquisitions, global IT, tax, treasury and legal. Net non-routine expense consists of items that the Company has determined are non-routine in nature and not allocated to the reportable operating segments. Net non-routine expense of $135.2 for the three months ended June 30, 2018 was due to the goodwill impairment charge of $90.0 and acquisition integration expenses of $14.5 primarily within selling and administrative expense and purchase accounting pre-tax charges for amortization of acquired intangibles of $29.3 . Net non-routine expense of $170.5 for the six months ended June 30, 2018 was due to the goodwill impairment charge of $90.0 and acquisition integration expenses of $29.6 , primarily within selling and administrative expense, and purchase accounting pre-tax charges for amortization of acquired intangibles of $60.5 . Net non-routine expense of $56.1 for the three months ended June 30, 2017 was primarily due to acquisition and divestiture related costs inclusive of integration expenses of $22.1 primarily within selling and administrative expense and purchase accounting pretax charges, which included deferred revenue of $10.3 and $32.8 in amortization of acquired intangibles. Net non-routine expense of $133.5 for the six months ended June 30, 2017 was primarily due to legal, acquisition and divestiture related costs of $17.4 inclusive of the mark-to-market impact on Diebold Nixdorf AG stock options and integration expenses of $34.9 primarily within selling and administrative expense and purchase accounting pretax charges, which included deferred revenue of $20.7 and $64.6 in amortization of acquired intangibles.

Supplemental Guarantor Information [Abstract]
Condensed Financial Statements [Text Block]	Supplemental Guarantor Information The Company issued the 2024 Senior Notes in an offering exempt from the registration requirements of the Securities Act. The 2024 Senior Notes are and will be guaranteed by certain of the Company's existing and future domestic subsidiaries. The following presents the condensed consolidating financial information separately for: (i) Diebold Nixdorf, Incorporated (the Parent Company), the issuer of the guaranteed obligations; (ii) Guarantor subsidiaries, on a combined basis, as specified in the indenture governing the Company's obligations under the 2024 Senior Notes; (iii) Consolidating entries and eliminations representing adjustments to (a) eliminate intercompany transactions between the Parent Company, the guarantor subsidiaries and the non-guarantor subsidiaries, (b) eliminate the investments in its subsidiaries, and (c) record consolidating entries; and (iv) Diebold Nixdorf, Incorporated and Subsidiaries on a consolidated basis. Each guarantor subsidiary is 100 percent owned by the Parent Company at the date of each balance sheet presented. The notes are fully and unconditionally guaranteed on a joint and several basis by each guarantor subsidiary. The guarantees of the guarantor subsidiaries are subject to release in limited circumstances only upon the occurrence of certain conditions. Each entity in the consolidating financial information follows the same accounting policies as described in the condensed consolidated financial statements, except for the use by the Parent Company and the guarantor subsidiaries of the equity method of accounting to reflect ownership interests in subsidiaries which are eliminated upon consolidation. Changes in intercompany receivables and payables related to operations, such as intercompany sales or service charges, are included in cash flows from operating activities. Intercompany transactions reported as investing or financing activities include the sale of capital stock of various subsidiaries, loans and other capital transactions between members of the consolidated group. Certain non-guarantor subsidiaries of the Parent Company are limited in their ability to remit funds to it by means of dividends, advances or loans due to required foreign government and/or currency exchange board approvals or limitations in credit agreements or other debt instruments of those subsidiaries.

Revenue from Contract with Cu29

Revenue from Contract with Customer (Policies)	6 Months Ended

Revenue Recognition [Abstract]
Revenue Recognition, Policy [Policy Text Block]	Revenue is measured based on consideration specified in a contract with a customer and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The Company's payment terms vary depending on the individual contracts and are generally fixed fee. The Company recognizes advance payments and billings in excess of revenue recognized as deferred revenue. In certain contracts where services are provided prior to billing, the Company recognizes a contract asset within trade receivables and other current assets. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. The Company recognizes shipping and handling fees billed when products are shipped or delivered to a customer and includes such amounts in net sales. Although infrequent, shipping and handling associated with outbound freight after control over a product has transferred to a customer is not a separate performance obligation, rather is accounted for as a fulfillment cost. Third-party freight payments are recorded in cost of sales. The Company includes a warranty in connection with certain contracts with customers, which are not considered to be separate performance obligations. The Company provides its customers a manufacturer’s warranty and records, at the time of the sale, a corresponding estimated liability for potential warranty costs. For additional information on product warranty refer to note 9. The Company also has extended warranty and service contracts available for its customers, which are recognized as separate performance obligations. Revenue is recognized on these contracts ratably as the Company has a stand-ready obligation to provide services when or as needed by the customer. This input method is the most accurate assessment of progress toward completion the Company can apply. Nature of goods and services The following is a description of principal solutions offered within the Company's two main industry segments that generate the Company's revenue. For more detailed information about reportable operating segments, see note 20. Contract assets are the rights to consideration in exchange for goods or services that the Company has transferred to a customer when that right is conditional on something other than the passage of time. Contract assets of the Company primarily relate to the Company's rights to consideration for goods shipped and services provided but not contractually billable at the reporting date. The contract assets are reclassified into the receivables balance when the rights to receive payment become unconditional. Contract liabilities are recorded for any services billed to customers and not yet recognizable if the contract period has commenced or for the amount collected from customers in advance of the contract period commencing. In addition, contract liabilities are recorded as advanced payments for products and other deliverables that are billed to and collected from customers prior to revenue being recognizable. Transaction price and variable consideration The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer, excluding amounts collected on behalf of third parties. This consideration can include fixed and variable amounts and is determined at contract inception and updated each reporting period for any changes in circumstances. The transaction price also considers variable consideration, time value of money and the measurement of any non-cash consideration, all of which are estimated at contract inception and updated at each reporting date for any changes in circumstances. The Company also applies the ‘as invoiced’ practical expedient in paragraph 606-10-55-18 related to performance obligations satisfied over time, which permits the Company to recognize revenue in the amount to which it has a right to invoice the customer if that amount corresponds directly with the value to the customer of the Company’s performance completed to date. Transaction price allocated to the remaining performance obligations As of June 30, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $2,600 . The Company expects to recognize revenue on the remaining performance obligations over the next twelve months. The Company enters into service agreements with cancellable terms after a certain period without penalty. Unsatisfied obligations reflect only the obligation during the initial term. The Company applies the practical expedient in paragraph 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one year or less. The Company also applies the ‘as invoiced’ practical expedient in paragraph 606-10-55-18 related to performance obligations satisfied over time which permits the Company to recognize revenue in the amount to which it has a right to invoice the customer if that amount corresponds directly with the value to the customer of the Company’s performance completed to date. Cost to obtain and cost to fulfill a contract The Company has minimal cost to obtain or fulfill contracts for customers for the periods presented. The Company pays commissions to the sales force based on multiple factors including but not limited to order entry, revenue recognition and portfolio growth. These incremental commission fees paid to the sales force meet the criteria to be considered a cost to obtain a contract, as they are directly attributable to a contract, incremental and management expects the fees are recoverable. The Company applies the practical expedient and recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. The costs that are not capitalized are included in cost of sales. The costs related to contracts with greater than a one-year term are immaterial and continue to be recognized in cost of sales. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of sales. The Company has minimal cost for shipping and handling costs for the periods presented. Changes in accounting policies Except for the changes below, the Company has consistently applied the accounting policies to all periods presented in these condensed consolidated financial statements. The Company adopted Topic 606, Revenue from Contracts with Customers , with a date of initial application of January 1, 2018. As a result, the Company has changed its accounting policy for revenue recognition as detailed below. The Company applied Topic 606 using the cumulative effect method - i.e., by recognizing the cumulative effect of initially applying Topic 606 as an adjustment to the opening balance of equity at January 1, 2018. Therefore, the comparative information has not been adjusted and continues to be reported under Topic 605. The Company applied the practical expedient related to assessment of contract modifications, whereby the Company is essentially allowed to use hindsight when assessing the effect of a modification and accounting for the modified contract as if it existed from the beginning of the original contract. The details of the significant changes and quantitative impact of the changes are set out below. Professional service contracts Previously, the Company recognized revenue for professional services contracts either on a milestone method or completed contract basis. Under Topic 606, the Company recognizes revenue when control transfers to a customer. As professional services can be highly customized for each customer, there is no alternative use for the services. When there is an enforceable right to payment for service completed combined with no alternative use of the services, the services meet criteria for over time revenue recognition. Revenue is recognized as the services are provided and as the customer benefits from the service. Revenue is recognized progressively based on the costs incurred method. When the professional services are not highly customized as in basic software installation services, customers do not take control of the services until they are completed. Therefore, the Company continues to recognize revenue for such contracts when the services are completed and customers formally accept them.
