Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	Commitments and Contingencies 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, 2020, 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 condensed 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 party to the proceedings described below: The Company has challenged multiple customs rulings in Thailand seeking to retroactively collect customs duties on previous imports of automated teller machines (ATMs). In August 2017, March 2019, August 2019, and May 2020 the Supreme Court of Thailand ruled in the Company's favor; finding each time that Customs' attempt to collect duties for importation of ATMs was improper. The surviving matters are immaterial and accordingly, the Company believes a loss is not probable and accordingly, 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, 2020 to be up to $57.5 for its material indirect tax matters. The aggregate risk related to indirect taxes is adjusted as the applicable statutes of limitations expire. Legal Contingencies At June 30, 2020, the Company was a party to several lawsuits that were incurred in the normal course of business, which neither individually nor in the aggregate were considered material by management in relation to the Company’s financial position or results of operations. In management’s opinion, the Company's condensed 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 is a party to the proceedings described below: Diebold Nixdorf Holding Germany GmbH, formerly Diebold Nixdorf Holding Germany Inc. & Co. KGaA (Diebold KGaA) is a party to two separate appraisal proceedings (Spruchverfahren) in connection with the purchase of all shares in its former listed subsidiary, Diebold Nixdorf AG. Both proceedings are pending at the same Chamber for Commercial Matters (Kammer für Handelssachen) at the District Court (Landgericht) of Dortmund (Germany). The first appraisal proceeding relates to the Domination and Profit and Loss Transfer Agreement, dated September 26, 2016 (the DPLTA) entered into by Diebold KGaA and former Diebold Nixdorf AG, which became effective on February 17, 2017. The DPLTA appraisal proceeding was 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 (of which 6.9 shares were then outstanding) and the annual recurring compensation of €2.82 per Diebold Nixdorf AG share offered in connection with the DPLTA. The second appraisal proceeding relates to the cash merger squeeze-out of minority shareholders of Diebold Nixdorf AG in 2019. The squeeze-out appraisal proceeding was filed by minority shareholders of Diebold Nixdorf AG challenging the adequacy of the cash exit compensation of €54.80 per Diebold Nixdorf AG share (of which 1.4 shares were then outstanding) in connection with the merger squeeze-out. In both appraisal proceedings, a court ruling would apply to all Diebold Nixdorf AG shares outstanding at the time when the DPLTA or the merger squeeze-out, respectively, became effective. Any cash compensation received by former Diebold Nixdorf AG shareholders in connection with the merger squeeze-out would be netted with any higher cash compensation such shareholder may still claim in connection with the DPLTA appraisal proceeding. While the Company believes that the compensation offered in connection with the DPLTA and the merger squeeze-out was in both cases fair, it notes that German courts often adjudicate increases of the cash compensation to plaintiffs in varying amounts in connection with German appraisal proceedings. Therefore, the Company cannot rule out that the first instance court or an appellate court may increase the cash compensation also in these appraisal proceedings. The Company, however, is convinced that its defense in both appraisal proceedings, which are still at preliminary stages, is supported by strong sets of facts and the Company will continue to vigorously defend itself in these matters. In July and August 2019, shareholders filed putative class action lawsuits alleging violations of federal securities laws in the United States District Court for the Southern District of New York and the Northern District of Ohio. The lawsuits collectively assert that the Company and three former officers made material misstatements regarding the Company’s business and operations, causing the Company’s common shares to be overvalued from February 14, 2017 to August 1, 2018. The lawsuits have been consolidated before a single judge in the United States District Court for the Southern District of New York and lead plaintiffs appointed. While management remains confident that it has valid defenses to these claims, as with any pending litigation, the Company is unable to predict the final outcome of this matter. In January 2020, the Company's Board of Directors received a demand letter from alleged shareholders to investigate and pursue claims for breach of fiduciary duty against certain current and former directors and officers based on the Company's statements regarding its business and operations, which are substantially similar to those challenged in the federal securities litigation. The Board has determined to defer consideration of the demand while the federal securities litigation remains pending.
Subsequent Events	Subsequent Event Issuance of Notes On July 20, 2020, Diebold Nixdorf, Incorporated issued $700.0 aggregate principal amount of 9.375% Senior Secured Notes due 2025 (the U.S. Notes) and its wholly-owned subsidiary, Diebold Nixdorf Dutch Holding B.V. (the Euro Notes Issuer), issued €350.0 aggregate principal amount of 9.000% Senior Secured Notes due 2025 (the Euro Notes and, together with the U.S. Notes, the New Notes) in private offerings exempt from registration under the Securities Act. The U.S. Notes were issued at a price of 99.031% of their principal amount, and the Euro Notes were issued at a price of 99.511% of their principal amount. The New Notes are or will be, as applicable, guaranteed on a senior secured basis by (i) all of Diebold Nixdorf, Incorporated’s existing and future direct and indirect U.S. subsidiaries that guarantee the obligations under the Credit Agreement and (ii) all of Diebold Nixdorf, Incorporated’s existing and future direct and indirect U.S. subsidiaries (other than securitization subsidiaries, immaterial subsidiaries and certain other subsidiaries) that guarantee any of the Euro Notes Issuer’s or Diebold Nixdorf, Incorporated’s or its subsidiary guarantors’ indebtedness for borrowed money (collectively, the U.S. Subsidiary Guarantors). Additionally, the U.S. Notes and the Euro Notes are guaranteed on a senior secured basis by the Euro Notes Issuer and Diebold Nixdorf, Incorporated, respectively. The New Notes are secured by first-priority liens on substantially all of the tangible and intangible assets of Diebold Nixdorf, Incorporated, the Euro Notes Issuer and the U.S. Subsidiary Guarantors, in each case subject to permitted liens and certain exceptions. The first-priority liens on the collateral securing the U.S. Notes and the related guarantees and the Euro Notes and the related guarantees are shared ratably among the Notes and the obligations under the Credit Agreement. The net proceeds from the offerings of the New Notes, along with cash on hand, were used to repay a portion of the amounts outstanding under the Credit Agreement, including all amounts outstanding under the Term Loan A Facility and Term Loan A-1 Facility and $193.8 of revolving credit loans, including all of the revolving credit loans due in December 2020, and for the payment of all related fees and expenses. Credit Agreement Amendment On July 20, 2020, the Company entered into the ninth amendment to the Credit Agreement (the Ninth Amendment) with the subsidiary borrowers named therein, the guarantors party thereto from time to time, JPMorgan Chase Bank, N.A., as administrative agent, and the other institutions named on the signature pages thereto. The Ninth Amendment amended the Credit Agreement to, among other things, extend the maturity of $330.0 of revolving credit commitments from April 30, 2022 to July 20, 2023 and amend the financial covenants in the Credit Agreement in connection with the extension of such maturities (and, effective as of the date of the Ninth Amendment, the Company terminated its other revolving credit commitments under the Revolving Facility other than approximately $39.0 of revolving credit commitments that still mature April 30, 2022).
