Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Newpark Resources, Inc. is a geographically diversified supplier providing products, as well as rentals and services. The accompanying unaudited condensed consolidated financial statements of Newpark Resources, Inc. and our wholly-owned subsidiaries, which we collectively refer to as “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 (“SEC”), 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, 2020. Our fiscal year end is December 31 and our first quarter represents the three-month period ended March 31. The results of operations for the first quarter of 2021 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 March 31, 2021 and our results of operations and cash flows for the first quarter of 2021 and 2020. All adjustments are of a normal recurring nature. Our balance sheet at December 31, 2020 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, 2020. We operate our business through two reportable segments: Fluids Systems and Industrial Solutions. Our Fluids Systems segment provides customized drilling, completion, and stimulation fluids solutions to oil and natural gas exploration and production (“E&P”) customers primarily in North America and Europe, the Middle East and Africa (“EMEA”), as well as certain countries in Asia Pacific and Latin America. Our Industrial Solutions segment includes our Site and Access Solutions business (historically reported as the Mats and Integrated Services segment), along with our Industrial Blending operations. Site and Access Solutions provides composite matting system rentals utilized for temporary worksite access, along with related site construction and services to customers in various markets including electrical utilities, E&P, pipeline, renewable energy, petrochemical, construction and other industries, primarily in the United States and Europe. We also sell our manufactured composite mats to customers around the world, with electrical utilities being the primary end-market. Our Industrial Blending operations began in 2020, leveraging our chemical blending capacity and technical expertise to enter targeted industrial end-markets. New Accounting Pronouncements Standards Adopted in 2021 Income Taxes: Simplifying the Accounting for Income Taxes. In December 2019, the Financial Accounting Standards Board (“FASB”) issued new guidance intended to simplify various aspects related to accounting for income taxes. We adopted this new guidance as of January 1, 2021. The adoption of this new guidance had no material impact on our financial statements or related disclosures. Standards Not Yet Adopted Debt: Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. In August 2020, the FASB issued new guidance which is intended to simplify the accounting for convertible instruments. This guidance will be effective for us in the first quarter of 2022. As our existing convertible instrument matures in December 2021, we do not expect the adoption of this guidance to have a material impact on our consolidated financial statements or related disclosures.
