Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies The accompanying unaudited condensed consolidated financial statements of Newpark Resources, Inc. and our wholly-owned subsidiaries, which we 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, 2015. Our fiscal year end is December 31 and 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 three and six months ended June 30, 2016 are not necessarily indicative of the results to be expected for the entire year. Unless otherwise stated, 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, 2016 and our results of operations for the three and six months ended June 30, 2016 and 2015 and our cash flows for the six months ended June 30, 2016 and 2015. All adjustments are of a normal recurring nature. Our balance sheet at December 31, 2015 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, 2015. Change in Accounting Estimates In 2016, we revised our estimates of the useful lives and residual values of certain of our composite mats included in rental fleet fixed assets within the Mats and Integrated Services segment. We now estimate that certain composite mats which were originally estimated to have a useful life of 7 years with zero residual value will have estimated useful lives ranging from 10 to 12 years with an estimated residual value of 20%. These changes in estimates were recognized prospectively beginning January 1, 2016 resulting in a reduction in depreciation expense for the Mats and Integrated Services segment of approximately $1.5 million and $3.1 million for the three and six months ended June 30, 2016, respectively. We expect these changes to have a similar effect on quarterly results going forward. New Accounting Pronouncements Standard adopted in 2016 In September 2015, the Financial Accounting Standards Board (“FASB”) issued updated guidance that eliminates the requirement to restate prior periods to reflect adjustments made to provisional amounts recognized in a business combination. The new guidance requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The new guidance was effective for us prospectively in the first quarter of 2016; however, the adoption did not have any effect on our consolidated financial statements. Standards not yet adopted In May 2014, the FASB amended the existing accounting standards for revenue recognition. The amendments are based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB deferred the effective date of the new guidance by one year and provided entities the option to early adopt the new guidance. The new guidance is effective for us in the first quarter of 2018 with early adoption permitted in the first quarter of 2017. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. We are currently evaluating the impact of these amendments on our consolidated financial statements, including the adoption and transition alternatives. In July 2015, the FASB issued updated guidance that simplifies the subsequent measurement of inventory. It replaces the current lower of cost or market test with the lower of cost or net realizable value test. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new guidance is effective prospectively for us in the first quarter of 2017 with early adoption permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements. In February 2016, the FASB issued updated guidance regarding accounting for leases. The new accounting standard provides principles for the recognition, measurement, presentation and disclosure of leases and requires lessees to recognize both assets and liabilities arising from financing and operating leases. The classification as either a financing or operating lease will determine whether lease expense is recognized based on an effective interest method basis or on a straight-line basis over the term of the lease, respectively. The new guidance is effective for us in the first quarter of 2019 with early adoption permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements. In March 2016, the FASB issued updated guidance that simplifies several aspects of the accounting for share-based payment transactions, including income tax consequences, forfeitures, classification of awards as either equity or liabilities, and classification of excess tax benefits on the statement of cash flows. The new guidance is effective for us in the first quarter of 2017 with early adoption permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements.
