When referring to “Weatherford” and using phrases such as “we,” “us,” and “our,” the intent is to refer to Weatherford International plc, a public limited company organized under the law of Ireland, and its subsidiaries as a whole or on a regional basis, depending on the context in which the statements are made.

These financial statements should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2017 included in our Annual Report on Form 10-K. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results expected for the year ending December 31, 2018. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, the reported amounts of revenues and expenses during the reporting period, and disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates and assumptions, including those related to uncollectible accounts receivable, lower of cost or net realizable value of inventories, equity investments, derivative financial instruments, intangible assets and goodwill, property, plant and equipment (“PP&E”), income taxes, accounting for long-term contracts, self-insurance, foreign currency exchange rates, pension and post-retirement benefit plans, disputes, litigation, contingencies and share-based compensation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates. Principles of Consolidation We consolidate all wholly-owned subsidiaries, controlled joint ventures and variable interest entities where the Company has determined it is the primary beneficiary. Investments in affiliates in which we exercise significant influence over operating and financial policies are accounted for using the equity method. All material intercompany accounts and transactions have been eliminated in consolidation. Reclassifications Certain prior year income statement amounts have been reclassified to conform to the current year presentation related to the adoption of new accounting standards. Net income for 2017 and shareholders’ equity as of December 31, 2017 were not affected by these reclassifications. See “Note 2 – New Accounting Pronouncements” for additional details. Currency Devaluation Charges Currency devaluation charges are included in current earnings in “Currency Devaluation Charges” on the accompanying Condensed Consolidated Statements of Operations. In the first quarter of 2018, currency devaluation charges of $26 million reflected the impact of the devaluation of the Angolan kwanza of $24 million and the Venezuelan bolivar of $2 million. In the first quarter of 2017, we had no currency devaluation charges. The devaluation of the Angolan kwanza was due to a change in the central bank policy in January 2018.
