Reorganization and Fresh Start Accounting | Reorganization and Fresh Start Accounting References to "Successor" or "Successor Company" relate to the financial position and results of operations of the reorganized company subsequent to July 31, 2017. References to "Predecessor" or "Predecessor Company" relate to the financial position and results of operations of the company through July 31, 2017. On July 31, 2017, the company and certain of its subsidiaries that had been named as additional debtors in the Chapter 11 proceedings emerged from bankruptcy after successfully completing its reorganization pursuant to the Second Amended Joint Prepackaged Chapter 11 Plan of Reorganization of Tidewater and its Affiliated Debtors (the “Plan”). Upon the company's emergence from Chapter 11 bankruptcy, the company qualified for and adopted fresh-start accounting in accordance with the provisions set forth in ASC 852, which requires the company to present its assets, liabilities, and equity as if it were a new entity upon emergence from bankruptcy. The implementation of the Plan and the application of fresh-start accounting materially changed the carrying amounts and classifications reported in the company’s consolidated financial statements and resulted in the company becoming a new entity for financial reporting purposes. As a result of the application of fresh-start accounting and the effects of the implementation of the Plan, the financial statements after July 31, 2017 are not comparable with the financial statements prior to July 31, 2017. Therefore, "black-line" financial statements are presented to distinguish between the Predecessor and Successor companies.
