Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	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 presented. 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, 2022. Except as disclosed herein, and with the exception of information in this Quarterly Report on Form 10-Q related to our emergence from the Restructuring Proceedings (defined in Note 2) and Fresh Start Accounting (defined below), there has been no material change in the information disclosed in the notes to the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2022. 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 for interim periods are not necessarily indicative of results for the entire year. The Company has reclassified the presentation of certain Predecessor information to conform to the Successor presentation. Bankruptcy Accounting and Fresh Start Accounting The consolidated financial statements included herein have been prepared using the going concern basis of accounting and in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic No. 852 – Reorganizations (ASC 852). See Note 2 and Note 3 for further detail. In accordance with ASC 852, we qualified for and adopted fresh start accounting (Fresh Start Accounting) upon emergence from the Restructuring Proceedings, at which point we became a new entity for financial reporting because (i) the holders of the then existing common shares of the Predecessor received less than 50% of the new shares of common stock of the Successor outstanding upon emergence and (ii) the reorganization value of the Company’s assets immediately prior to confirmation of the Plans (defined in Note 2) was less than the total of all post-petition liabilities and allowed claims. Upon adoption of Fresh Start Accounting as reflected in Note 3 – Fresh Start Accounting, the reorganization value derived from the enterprise value associated with the Plans was allocated to the Company’s identifiable tangible and intangible assets and liabilities based on their fair values (except for deferred income taxes), with the remaining excess value allocated to goodwill in accordance with ASC 805 – Business Combinations. Deferred income tax amounts were determined in accordance with ASC 740 – Income Taxes. References to “Predecessor” relate to the Condensed Consolidated Balance Sheets as of December 31, 2022, and Condensed Consolidated Statements of Operations for the quarter and nine months ended September 30, 2022 and for the periods from January 1, 2023 and July 1, 2023 through and including the adjustments from the application of Fresh Start Accounting on August 11, 2023 (Predecessor Period). References to “Successor” relate to the Condensed Consolidated Balance Sheet of the reorganized Company as of September 30, 2023 and Condensed Consolidated Statements of Operations for the period from August 12, 2023 through September 30, 2023 (Successor Period) and are not comparable to the Condensed Consolidated Financial Statements of the Predecessor as indicated by the “black line” division in the financial statements and footnote tables, which emphasizes the lack of comparability between amounts presented. In addition, Note 3 – Fresh Start Accounting provides a summary of the Condensed Consolidated Balance Sheets as of August 11, 2023 in the first column, and then presents adjustments to reflect the Plans and fresh start impacts to derive the opening Successor Condensed Consolidated Balance Sheets as of August 12, 2023. The Company’s financial results for future periods following the application of Fresh Start Accounting will be different from historical trends and the differences may be material. Principles of Consolidation We consolidate all wholly owned subsidiaries and controlled joint ventures. All material intercompany accounts and transactions have been eliminated in consolidation. Recently Issued Accounting Guidance The Company considers the applicability and impact of all Accounting Standards Updates (ASUs) issued by the FASB. In March 2020, the FASB issued guidance that provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by the transition away from reference rates expected to be discontinued to alternative reference rates. The guidance was effective upon issuance and may be applied prospectively to contract modifications made and hedging relationships entered into on or before December 31, 2024. The standard does not materially impact the Company's consolidated financial statements. Although there are other new accounting pronouncements issued by the FASB, the Company does not believe these pronouncements will have a material impact on its consolidated financial statements.
