| Basis of Presentation and Significant Accounting Policies                           | Basis of Presentation and Significant Accounting PoliciesNewpark Resources, Inc. is a geographically diversified supplier providing environmentally-sensitive products, as well as rentals and services to customers across multiple industries. The accompanying unaudited condensed consolidated financial statements of Newpark Resources, Inc. and our wholly-owned subsidiaries, which we collectively refer to as the “Company,” “we,” “our,” or “us,” have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission, and do not include all information and footnotes required by the accounting principles generally accepted in the United States (“U.S. GAAP”) for complete financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023. Our fiscal year end is December 31, our second quarter represents the three month period ended June 30, and our first half represents the six month period ended June 30. The results of operations for the second quarter and first half of 2024 are not necessarily indicative of the results to be expected for the entire year. Unless otherwise noted, all currency amounts are stated in U.S. dollars.In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary to present fairly our financial position as of June 30, 2024, our results of operations for the second quarter and first half of 2024 and 2023, and our cash flows for the first half of 2024 and 2023. All adjustments are of a normal recurring nature. Our balance sheet at December 31, 2023 is derived from the audited consolidated financial statements at that date.The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. For further information, see Note 1 in our Annual Report on Form 10-K for the year ended December 31, 2023.We currently operate our business through two reportable segments: Fluids Systems and Industrial Solutions. •Our Fluids Systems segment provides drilling and completion fluids products and related technical services to customers for oil, natural gas, and geothermal projects primarily in Europe, the Middle East and Africa (“EMEA”), and North America, as well as certain countries in Asia Pacific.Over the past few years, our primary focus within the Fluids Systems segment has been the transformation into a more agile and simplified business focused on key markets, while monetizing assets in underperforming or sub-scale markets and reducing our invested capital, particularly in the U.S. In 2023, we exited our stimulation chemicals product line, certain operations for offshore Australia, and our operations in Chile. In September 2023, we launched a formal sale process for substantially all the Fluids Systems business. See Note 2 for additional information. •Our Industrial Solutions segment provides temporary worksite access solutions, including the rental of our recyclable composite matting systems, along with related site construction and services to customers in various markets including power transmission, oil and natural gas exploration and production (“E&P”), pipeline, renewable energy, petrochemical, construction and other industries, primarily in the United States and United Kingdom. We also sell our manufactured recyclable composite mats to customers around the world, with power transmission being the primary end-market.New Accounting PronouncementsStandards Not Yet AdoptedSegment Reporting. In November 2023, the Financial Accounting Standards Board (“FASB”) issued new guidance which is intended to improve reportable segment disclosure requirements through enhanced disclosures. The amendments require disclosure of significant segment expenses regularly provided to the chief operating decision maker (“CODM”) as well as other segment items, extend certain annual disclosures to interim periods, clarify the applicability to single reportable segment entities, permit more than one measure of profit or loss to be reported under certain conditions, and require disclosure of the title and position of the CODM. This guidance will be effective for us for the year ending December 31, 2024, and will be applied retrospectively. We are currently evaluating the impact of the new guidance on our consolidated financial statements and related disclosures. These requirements are not expected to have an impact on our financial statements, but will result in expanded reportable segment disclosures.Income Taxes: Improvements to Income Tax Disclosures. In December 2023, the FASB issued new guidance which is intended to enhance the transparency and decision usefulness of income tax disclosures. This guidance will be effective for us in the first quarter of 2025. We are currently evaluating the impact of the new guidance on our consolidated financial statements and related disclosures. These requirements are not expected to have an impact on our financial statements, but will impact our income tax disclosures. |
