Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Organization and Nature of Operations Weatherford International plc (“Weatherford Ireland”), an Irish public limited company and Swiss tax resident, together with its subsidiaries (“Weatherford,” the “Company,” “we,” “us” and “our”), is a multinational oilfield service company. Weatherford is one of the world’s leading providers of equipment and services used in the drilling, evaluation, completion, production and intervention of oil and natural gas wells. We operate in approximately 90 countries, which are located in nearly all of the oil and natural gas producing regions in the world. Many of our businesses, including those of our predecessor companies, have been operating for more than 50 years. On June 17, 2014, we completed the change in our place of incorporation from Switzerland to Ireland, whereby Weatherford Ireland became the new public holding company and the parent of the Weatherford group of companies (the “Merger”). The Merger was effected through an agreement between Weatherford International Ltd. (“Weatherford Switzerland”) and Weatherford Ireland pursuant to which each registered share of Weatherford Switzerland was exchanged for the allotment of one ordinary share of Weatherford Ireland. The authorized share capital of Weatherford Ireland includes 1.356 billion ordinary shares with a par value of $0.001 per share. Our ordinary shares are listed on the New York Stock Exchange (the “NYSE”) under the symbol “WFT,” the same symbol under which Weatherford Switzerland registered shares were previously listed. In February 2009, we completed a share exchange transaction in which Weatherford International Ltd., a Bermuda exempted company (“Weatherford Bermuda”), and our then parent company, became a wholly owned subsidiary of Weatherford Switzerland, for purposes of changing the Company’s place of incorporation from Bermuda to Switzerland. Prior to 2002, our parent company was Weatherford International, Inc., a Delaware corporation (“Weatherford Delaware”), until we moved our incorporation to Bermuda in 2002. Weatherford Bermuda and Weatherford Delaware continue to be wholly owned subsidiaries of Weatherford Ireland. In 2013, Weatherford Delaware converted its corporate form and now exists as Weatherford International, LLC, a Delaware limited liability company. 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. All material intercompany accounts and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year presentation related to the adoption of new accounting standards. Net income and shareholders’ equity were not affected by these reclassifications. See subsection entitled “New Accounting Pronouncements” for additional details. Investments in affiliates in which we exercise significant influence over operating and financial policies are accounted for using the equity method. We recognize equity in earnings of unconsolidated affiliates in Selling, General and Administration attributable to segments in our Consolidated Statements of Operations (see “ Note 11 – Equity Investments ”). Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts 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 market of inventories, equity investments, derivative financial instruments, intangible assets and goodwill, property, plant and equipment (“PP&E”), income taxes, percentage-of-completion 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. Disputes, Litigation and Contingencies We accrue an estimate of the probable and estimable cost to resolve certain legal and investigation matters. For matters not deemed probable and reasonably estimable, we have not accrued any amounts in accordance with U.S. GAAP. Our contingent loss estimates are based upon an analysis of potential results, assuming a combination of probable litigation and settlement strategies. The accuracy of these estimates is impacted by the complexity of the associated issues. Cash and Cash Equivalents We consider all highly liquid investments with original maturities of three months or less to be cash equivalents. Allowance for Doubtful Accounts We establish an allowance for doubtful accounts based on various factors including historical experience, the current aging status of our customer accounts, the financial condition of our customers and the business and political environment in which our customers operate. Provisions for doubtful accounts are recorded when it becomes probable that customer accounts are uncollectible. Major Customers and Credit Risk Substantially all of our customers are engaged in the energy industry. This concentration of customers may impact our overall exposure to credit risk, either positively or negatively, in that customers may be similarly affected by changes in economic and industry conditions. We perform on-going credit evaluations of our customers and do not generally require collateral in support of our trade receivables. We maintain allowances for potential credit losses, and actual losses have historically been within our expectations. International sales also present various risks, including risks of war, civil disturbances and governmental activities that may limit or disrupt markets, restrict the movement of funds, or result in the deprivation of contract rights or the taking of property without fair consideration. Most of our international sales are to large international or national oil companies and these sales have resulted in a concentration of receivables from certain national oil companies in Latin America. As of December 31, 2016 , Latin America accounted for 38% of our net outstanding accounts receivables. Venezuela, Ecuador and Mexico represent 43% , 16% and 10% , respectively, of the Latin America balance. In 2016, we accepted a note with a face value of $120 million from Petroleos de Venezuela, S.A. (“PDVSA”) in exchange for $120 million in net trade receivables. The note had a three year term at a 6.5% stated interest rate. We carried the note at fair value and recognized a loss in the second quarter of 2016 of $84 million to adjust the note to fair value. In the fourth quarter of 2016, we sold the economic rights in the note receivable for $44 million and recognized a gain of $8 million . During 2016 , 2015 and 2014 , no individual customer accounted for more than 10% of our consolidated revenues. Inventories We value our inventories at lower of cost or market using either the first-in, first-out (“FIFO”) or average cost method. Cost represents third-party invoice or production cost. Production cost includes material, labor and manufacturing overhead. Work in process and finished goods inventories include the cost of materials, labor and manufacturing overhead. To maintain a book value that is the lower of cost or market, we maintain reserves for excess, slow moving and obsolete inventory. We regularly review inventory quantities on hand and record provisions for excess, slow moving and obsolete inventory. Property, Plant and Equipment We carry our property, plant and equipment, both owned and under capital lease, at cost less accumulated depreciation. The carrying values are based on our estimates and judgments relative to capitalized costs, useful lives and salvage value, where applicable. We expense maintenance and repairs as incurred. We capitalize expenditures for improvements as well as renewals and replacements that extend the useful life of the asset. We depreciate our fixed assets on a straight-line basis over their estimated useful lives, allowing for salvage value where applicable. Our depreciation expense was $896 million , $1.1 billion and $1.3 billion for the years ended December 31, 2016 , 2015 and 2014 , respectively. We classify our rig assets as “ Rental and Service Equipment ” on the Consolidated Balance Sheets . The estimated useful lives of our major classes of PP&E are as follows: Major Classes of Property, Plant and Equipment Estimated Useful Lives Buildings and leasehold improvements 10 – 40 years or lease term Rental and service equipment 2 – 20 years Machinery and other 2 – 12 years Goodwill Goodwill represents the excess of consideration paid over the fair value of net tangible and identifiable intangible assets acquired in a business combination. Goodwill is not amortized but is evaluated for impairment. We perform an impairment test for goodwill annually as of October 1 or more frequently if indicators of potential impairment exist that would more-likely-than-not reduce the fair value of the reporting unit below its carrying value. Goodwill impairment is evaluated using a two-step process. The first step of the goodwill impairment test involves a comparison of the fair value of each of our reporting units with their carrying values. We have the option to assess qualitative factors to determine if it is necessary to perform the first step of the impairment test. If it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying value, further testing is not required. If the fair value of a reporting unit is less than the recorded book value of the reporting unit’s net assets (including goodwill), then a hypothetical purchase price allocation is performed on the reporting unit’s assets and liabilities using the fair value of the reporting unit as the purchase price in the calculation. If the implied fair value of goodwill is less than the recorded amount of goodwill, the recorded goodwill is written down to the new amount. Intangible Assets Our intangible assets, excluding goodwill, are acquired technology, licenses, patents, customer relationships and other identifiable intangible assets. Intangible assets are amortized on a straight-line basis over their estimated economic lives generally ranging from two to 20 years, except for intangible assets with indefinite lives, which are not amortized. As many areas of our business rely on patents and proprietary technology, we seek patent protection both inside and outside the U.S. for products and methods that appear to have commercial significance. We capitalize patent defense costs when we determine that a successful defense is probable. Long-Lived Assets We initially record our long-lived assets at cost, and review on a regular basis to determine whether any events or changes in circumstances indicate the carrying amount of the assets may not be recoverable. Factors that might indicate a potential impairment may include, but are not limited to, significant decreases in the market value of the long-lived asset, a significant change in the long-lived asset’s physical condition, the introduction of competing technologies, legal challenges, a reduction in the utilization rate of the assets, a change in industry conditions or a reduction in cash flows associated with the use of the long-lived asset. If these or other factors indicate the carrying amount of the asset may not be recoverable, we determine whether an impairment has occurred through analysis of undiscounted cash flow of the asset at the lowest level that has an identifiable cash flow. If an impairment has occurred, we recognize a loss for the difference between the carrying amount and the fair value of the asset. We estimate the fair value of the asset using market prices when available or, in the absence of market prices, based on an estimate of discounted cash flows or replacement cost. Cash flows are generally discounted using an interest rate commensurate with a weighted average cost of capital for a similar asset. Research and Development Expenditures Research and development expenditures are expensed as incurred. Environmental Expenditures Environmental expenditures that relate to the remediation of an existing condition caused by past operations and that do not contribute to future revenues are expensed. Liabilities for these expenditures are recorded when it is probable that obligations have been incurred and costs can be reasonably estimated. Estimates are based on available facts and technology, enacted laws and regulations and our prior experience in remediation of contaminated sites. Derivative Financial Instruments We record derivative instruments on the balance sheet at their fair value as either assets or liabilities. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income (loss), depending on whether the derivative is designated as part of a hedge relationship, and if so, the type of hedge. Foreign Currency Results of operations for our foreign subsidiaries with functional currencies other than the U.S. dollar are translated using average exchange rates during the period. Assets and liabilities of these foreign subsidiaries are translated using the exchange rates in effect at the balance sheet dates, and the resulting translation adjustments are included in Accumulated Other Comprehensive Loss, a component of shareholders’ equity. For our subsidiaries that have a functional currency that differs from the currency of their balances and transactions, inventories, PP&E and other non-monetary assets and liabilities, together with their related elements of expense or income, are remeasured into the functional currency using historical exchange rates. All monetary assets and liabilities are remeasured into the functional currency at current exchange rates. All revenues and expenses are translated into the functional currency at average exchange rates. Remeasurement gains and losses for these subsidiaries are recognized in our results of operations during the period incurred. We had net foreign currency losses, net of gains and losses on foreign currency derivatives (See “ Note 15 – Derivative Instruments ”), but excluding charges relating to the Venezuelan bolivar fuertes (“bolivar”), the Angolan kwanza, Argentinian peso, Egyptian pound and Kazakhstani tenge as described under the caption “Currency Devaluation and Related Charges,” of $9 million , $53 million and $18 million in 2016 , 2015 and 2014 , respectively, which are included in “ Other Income (Expense), Net ” on the accompanying Consolidated Statements of Operations . Currency Devaluation and Related Charges Currency devaluation charges are included in current earnings in “ Currency Devaluation Charges ” on the accompanying Consolidated Statements of Operations. In 2016, currency devaluation charges include charges related to the Angolan kwanza of $31 million and the Egyptian pound of $10 million . In 2015, currency devaluations charges of $85 million include charges related to the Angolan kwanza of $39 million , the Venezuelan bolivar of $26 million , the Argentina peso of $11 million and Kazakhstani tenge of $9 million . In 2014, currency charges include $245 million related to the Venezuelan bolivar. The charges were related to our adoption of the SICAD II exchange rate provided by Venezuela’s Supplementary Foreign Currency Administration System approximately of 50 Venezuelan bolivars per U.S. dollar. See “ Note 4 – Supplementary Information ” for additional information related to currency devaluation charges. At December 31, 2016 our net monetary asset position denominated in Angolan kwanza was approximately $116 million . The net monetary positions denominated in Venezuelan bolivar, Argentine peso and Kazakhstani tenge were not material. Share-Based Compensation We account for all share-based payment awards, including shares issued under employee stock purchase plans, stock options, restricted shares, restricted share units and performance units by measuring these awards at the date of grant and recognizing the grant date fair value as an expense, net of expected forfeitures, over the service period, which is usually the vesting period. Income Taxes Income taxes have been provided based upon the tax laws and rates in the countries in which our operations are conducted and income is earned. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance for deferred tax assets is recorded when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized. The impact of an uncertain tax position taken or expected to be taken on an income tax return is recognized in the financial statements at the largest amount that is more likely than not to be sustained upon examination by the relevant taxing authority. Revenue Recognition Revenue is recognized when all of the following criteria have been met: (1) evidence of an arrangement exists; (2) delivery to and acceptance by the customer has occurred; (3) the price to the customer is fixed or determinable; and (4) collectability is reasonably assured. Our services and products are generally sold based upon purchase orders, contracts or other persuasive evidence of an arrangement with our customers that include fixed or determinable prices but do not generally include right of return provisions or other significant post-delivery obligations. Our products are produced in a standard manufacturing operation, even if produced to our customer’s specifications. Revenue is recognized for products upon delivery and when the customers assume the risks and rewards of ownership. Revenue is recognized for services when they are rendered. Both contract drilling and pipeline service revenue is contractual by nature and generally governed by day-rate based contracts. We recognize revenue for day-rate contracts as the services are rendered. Up-front payments for preparation and mobilization of equipment and personnel in connection with new drilling contracts are deferred along with any related incremental costs incurred directly related to preparation and mobilization. The deferred revenue and costs are recognized over the primary contract term using the straight-line method. Costs of relocating equipment without contracts are expensed as incurred. Demobilization fees received are recognized, along with any related expenses, upon completion of contracts. We incur rebillable expenses including shipping and handling, third-party inspection and repairs, and customs costs and duties. We recognize the revenue associated with these rebillable expenses when reimbursed by customers as Product Revenues and all related costs as Cost of Products in the accompanying Consolidated Statements of Operations . Percentage-of-Completion Revenue from certain long-term construction type contracts is reported based on the percentage-of-completion method of accounting. This method of accounting requires us to calculate contract profit to be recognized in each reporting period for each contract based upon our projections of future outcomes, which include: • estimates of the available revenue under the contracts; • estimates of the total cost to complete the project; • estimates of project schedule and completion date; • estimates of the extent of progress toward completion; and • change order amounts or claims included in revenue. Measurements of progress are based on costs incurred to date as a percentage of total estimated costs or output related to physical progress. At the outset of each contract, we prepare a detailed analysis of our estimated cost to complete the project. Risks related to service delivery, usage, productivity and other factors are considered in the estimation process. We periodically evaluate the estimated costs, claims, change orders and percentage-of-completion at the contract level. The recording of profits and losses on long-term contracts requires an estimate of the total profit or loss over the life of each contract. This estimate requires consideration of total contract value, change orders and claims, less costs incurred and estimated costs to complete. Anticipated losses on contracts are recorded in full in the period in which they become evident. Profits are recorded based upon the total estimated contract profit multiplied by the current estimated percentage complete for the contract. There are many factors that impact future costs, including but not limited to weather, inflation, customer activity levels and budgeting constraints, labor and community disruptions, timely availability of materials, productivity and other factors. Earnings per Share Basic earnings per share for all periods presented equals net income divided by the weighted average number of our shares outstanding during the period including participating securities. Diluted earnings per share is computed by dividing net income by the weighted average number of our shares outstanding during the period including participating securities, adjusted for the dilutive effect of our stock options, restricted shares and performance units. Unvested share-based payment awards and other instruments issued by the Company that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are participating securities and are included in the computation of earnings per share following the two-class method. Accordingly, we include our restricted share awards (“RSA”) and the outstanding warrant, which contain the right to receive dividends, in the computation of both basic and diluted earnings per share when diluted. New Accounting Pronouncements Accounting Changes In April 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs , which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. We adopted ASU 2015-03 in the first quarter of 2016 retrospectively, which reduced Long-term debt and Other non-current assets by $27 million as of December 31, 2015. In November 2015, the FASB issued ASU 2015-17 , Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which eliminates the current requirement to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. We adopted ASU 2015-17 in the fourth quarter of 2016 and have reclassified net current deferred tax assets of $257 million and net current deferred tax liabilities of $33 million into non-current deferred tax asset and liabilities. We adopted ASC 2015-17 prospectively and no prior periods have been restated to conform to the new presentation. The adoption has no effect on net income or cash flows. Accounting Standards Issued Not Yet Adopted In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory , which eliminates a current exception in U.S. GAAP to the recognition of the income tax effects of temporary differences that result from intra-entity transfers of non-inventory assets. The intra-entity exception is being eliminated under the ASU. The standard is required to be applied on a modified retrospective basis and will be effective beginning with the first quarter of 2018. Early adoption is permitted, and we are evaluating the impact that this new standard will have on our Consolidated Financial Statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . ASU 2016-15 provides guidance on the cash flow reporting of certain issues that were either unclear or not addressed under existing U.S. GAAP. The standard requires the retrospective transition method to each period presented and will be effective beginning with the first quarter of 2018, although early adoption is permitted. We are evaluating the impact that ASC 2016-15 will have on our Consolidated Statements of Cash Flows. In June 2016, the FASB issued ASU 2016-13 , Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. The new standard applies to trade receivables and requires expected credit losses to be based on past events, current conditions and reasonable and supportable forecasts that affect the instrument’s collectability. The new standard will be effective for us beginning with the first quarter of 2020. Early adoption is permitted in 2019. We are evaluating the impact that this new standard will have on our Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which impacts certain aspects of the accounting for share-based payment transactions. This update provides various transition requirements that include both prospective, modified retrospective and retrospective application guidance. The new standard will be effective for us beginning with the first quarter of 2017. Early adoption is permitted, but it must include all amendments in the same period. We are evaluating the impact that this new standard will have on our Consolidated Financial Statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires a lessee to recognize a lease asset and lease liability for most leases, including those classified as operating leases under existing GAAP. The ASU also changes the definition of a lease and requires expanded quantitative and qualitative disclosures for both lessees and lessors. Under ASU 2016-02, we will revise our leasing policies to require most of the leases, where we are the lessee, to be recognized on the balance sheet as a lease asset and lease liability whereas currently we do not recognize operating leases on our balance sheet. Further, we will separate leases from other contracts where we are either the lessor or lessee when the rights conveyed under the contract indicate there is a lease, where we may not be required to do so under existing policies. While we cannot calculate the impact ASU 2016-02 will have on Weatherford’s financial statements, we anticipate that Weatherford’s assets and liabilities will increase by a significant amount. This standard will be effective for us beginning with the first quarter of 2019. We do not anticipate adopting ASU 2016-02 early, which is permitted under the standard. ASU 2016-02 requires lessees and lessors to recognize and measure leases at the beginning of the earlies period presented using a modified retrospective transition method but permits certain practical expedients to be applied, which may exclude certain leases that commenced before the effective date. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory , which requires inventory not measured using either the last in, first out (LIFO) or the retail inventory method to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable cost of completion, disposal, and transportation. The new standard will be effective for us beginning with the first quarter of 2017, and will be applied prospectively. Early adoption is permitted. We do not expect the impact of our adoption to have a material effect on our Consolidated Financial Statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , which will replace most existing revenue recognition guidance in GAAP. ASU 2014-09 will require an entity to recognize revenue 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. ASU 2014-09 requires a five-step approach to recognizing revenue: 1) identify the contract, 2) identify performance obligations, 3) determine the transaction price, 4) allocate the transaction price, and 5) recognize revenue. Subsequent to ASU 2014-09’s issuance, Topic 606 has been affected by other FASB updates that address certain aspects or Topic 606 or revised the effective date of the accounting changes. Under ASU 2014-09, we will revise our revenue recognition policy to require revenue recognition when control passes. This is a change from current policies, which generally require revenue recognition when delivery has occurred and risk and rewards of ownership have passed. Further, we will also begin estimating variable revenues and recognizing them sooner, whereas under current policies such variable revenues were generally not recognized until their collection was determinable. The impact of these and other changes will be to either slow the recognition of revenue in certain situations and to accelerate it in others. The expected impact is not yet determinable. The changes are not expected to have any direct impact to our cash flows. We intend to adopt ASU 2014-09 as of its effective date in the first quarter 2018. ASU 2014-09 permits two transition methods: the retrospective or the modified retrospective. The retrospective method is applied by restating all prior years whereas the modified retrospective method requires the recognition of a cumulative effect as an adjustment to opening retained earnings. Weatherford is currently evaluating the transition method it will select, but will likely utilize the modified retrospective method. We have planned and commenced our implementation of ASU 2014-09. We are in the process of assessing differences from current accounting practices (gap analysis). Remaining implementation matters include completing the gap analysis, implementing appropriate technology enhancements, establishing new policies, procedures, and controls, and quantifying any adoption date adjustments.

Business Combinations [Abstract]
Business Combinations and Dispositions	Business Combinations and Divestitures Acquisitions From time to time, we acquire businesses we believe are important to our long-term strategy. Results of operations for acquisitions are included in the accompanying Consolidated Statements of Operations from the date of acquisition. The balances included in the Consolidated Balance Sheets related to current year acquisitions are based on preliminary information and are subject to change when final asset valuations are obtained and the potential for liabilities has been evaluated. The purchase price for the acquisitions is allocated to the net assets acquired based upon their estimated fair values at the date of acquisition. We did not complete any material acquisitions or divestitures during the year ended December 31, 2016 or 2015 . In April 2014, we acquired an additional 30% ownership interest in a joint venture in China. We paid $13 million for the incremental interest, thereby increasing our ownership interest from 45% to 75% and gaining control of the joint venture. As a result of this transaction, we adjusted our previously held equity investment to fair value, recognizing a $16 million gain, and we applied the consolidation method of accounting, recognizing $6 million of goodwill and $30 million of cash. In May 2012, we acquired a company that designs and produces well completion tools. Our purchase consideration included a contingent consideration valued at approximately $17 million that we paid at settlement during the fourth quarter of 2016. This contingent consideration arrangement is dependent on the acquired company’s revenue and is marked to market through current earnings in each reporting period prior to settlement. The liability is valued using Level 3 inputs. Divestitures On December 31, 2014, we completed the sale of our engineered chemistry and Integrity drilling fluids businesses for proceeds totaling $750 million less estimated working capital adjustments of $16 million and transaction fees of $12 million and recognized a gain of $250 million . In addition, we disposed of all of our shares in Proserv Group Inc. (“Proserv”) and recognized a gain of $65 million resulting from this transaction. The income before income taxes related to our engineered chemistry and Integrity drilling fluids businesses of $57 million in 2014 were segregated from our Consolidated Financial Statements. The major classes of assets sold in this transaction included $48 million of accounts receivable, $99 million of inventory and $369 million of other assets primarily comprised of PP&E and other intangible assets. Liabilities of $44 million were also transferred in the sale, of which $32 million were current liabilities. In September 2014, we completed the sale of our pipeline and specialty services business. We received cash consideration of $246 million ( $245 million , net of cash disposed) and recognized a gain of approximately $49 million resulting from this transaction. In July 2014, we completed the sale of our land drilling and workover rig operations in Russia and Venezuela. We received cash consideration upon closing of $499 million ( $486 million , net of cash disposed). As a result of our commitment to sell, we recorded a $143 million long-lived assets impairment loss and a $121 million goodwill impairment loss in the second quarter of 2014. Of the $121 million goodwill impairment loss, $95 million pertained to goodwill attributable to our divested land drilling and workover rig operations in Russia. See “ Note 9 – Goodwill ” for additional information regarding the goodwill impairment. On October 7, 2013, we completed the sale of our 38.5% equity interest in Borets International Limited (“Borets”) for $400 million , net of settlement items. We recorded a gain on sale of $18 million . The consideration consisted of $359 million in cash and a three -year $30 million promissory note. In the fourth quarter of 2016, we received the principal and interest due on the promissory note.

Restructuring and Related Activities [Abstract]
Restructuring Charges	Restructuring Charges In response to continuing fluctuation of crude oil prices and lower levels of exploration and production spending in 2016, we initiated an additional plan to reduce our overall costs and workforce to better align with anticipated activity levels. This cost reduction plan (the “2016 Plan”) included a workforce reduction and other cost reduction measures initiated across our geographic regions. In connection with the 2016 Plan, we recognized restructuring charges of $280 million in 2016, which include severance benefits of $196 million , restructuring related asset charges of $40 million and other restructuring charges of $44 million . Other restructuring charges include contract termination costs, relocation and other associated costs. In the fourth quarter of 2014, we announced a cost reduction plan (the “2015 Plan”), which included a worldwide workforce reduction and other cost reduction measures. In connection with the 2015 Plan, we recognized restructuring charges of $232 million in 2015 and $58 million in 2014. Our restructuring charges during 2015 in connection with the 2015 Plan include severance benefits of $149 million , restructuring related asset charges of $64 million and other restructuring charges of $19 million . Restructuring related asset charges include asset write-offs of $26 million related to Yemen due to the political disruption and $38 million in other regions. Other restructuring charges include exit costs, contract termination costs, relocation costs and other associated costs. Our restructuring charges during 2014 in connection with the 2015 Plan include severance benefits of $58 million . In the first quarter of 2014, we announced a cost reduction plan (the “2014 Plan”), which included a worldwide workforce reduction and other cost reduction measures. In connection with the 2014 Plan, we recognized restructuring charges of $273 million in 2014. The restructuring charges in connection with the 2014 Plan include restructuring related asset charges of $135 million , severance benefits of $114 million and other restructuring charges of $24 million . Other restructuring charges include contract termination costs, relocation and other associated costs. The impairments recognized in connection with the 2014 Plan primarily pertain to operations in our Middle East/North Africa (“MENA”) region, where geopolitical issues and recent disruptions in North Africa, primarily Libya, resulted in the decisions in the third quarter of 2014 to exit product lines in selected markets. The 2014 Plan activities resulted in $106 million of cash payments in 2014. The following tables present the components of the restructuring charges by segment and plan for the years ended December 31, 2016, 2015 and 2014.

Supplemental Cash Flow Information Related Text	Supplementary Information Cash paid for interest and income taxes was as follows: Year Ended December 31, (Dollars in millions) 2016 2015 2014 Interest paid, net of capitalized interest $ 467 $ 477 $ 511 Income taxes paid, net of refunds 161 331 386 In 2016, currency devaluation charges reflect the impact of the devaluation of $41 million related to the Angolan kwanza and Egyptian pound. Currency devaluation charges are included in “ Currency Devaluation Charges ” on the accompanying Consolidated Statements of Operations. In 2015, currency devaluation charges reflect the impacts of the devaluation of the Angolan kwanza and Argentine peso and the recognized remeasurement charges related to the Venezuelan bolivar and the Kazakhstani tenge resulting in a $85 million pre-tax charge of which $43 million negatively impacted cash. The Angolan kwanza charges reflect currency devaluations in 2015 and the Kazakhstan tenge depreciated as a result of the National Bank of Kazakhstan abandoning its peg of the tenge to the U.S. dollar. The devaluation of the Argentine peso was due to the modifying of currency control restrictions on purchasing foreign currencies by the Argentine Central Bank. The Venezuelan bolivar charge reflects remeasurement charges when we began using the latest Venezuelan currency exchange system known as the “Marginal Currency System” or SIMADI. The SIMADI opened for trading February 12, 2015, replacing the Venezuela Supplementary Foreign Currency Administration System auction rate (“SICAD II”) mechanism. The SIMADI is intended to provide limited access to a free market rate of exchange. In December 2014, we remeasured our Venezuelan bolivar denominated monetary assets and liabilities (primarily cash, accounts receivables, trade payables and other current liabilities) to the SICAD II exchange rate of 50 Venezuelan bolivars per U.S. dollar resulting in a $245 million pre-tax charge of which $92 million was related to the remeasurement of cash held in Venezuelan bolivar. During 2016, 2015 and 2014 we received proceeds from the asset disposition totaling $49 million , $37 million and $59 million , respectively. In 2016, we had non-cash investing and financing activities related to capital lease of equipment of $25 million .

Percentage of Completion Contracts	Percentage-of-Completion Contracts During 2016 , we were break-even for our Zubair contract and cumulative estimated loss from the Iraq contracts was $532 million as of December 31, 2016 . On May 26, 2016, we entered into an agreement with our customer containing the terms and conditions of the settlement on the Zubair contract. The settlement to be paid to us is a gross amount of $150 million , of which $62 million and $72 million was received in the second and third quarters of 2016, respectively. The settlement includes variation order requests, claims for extension of time, payments of remaining contract milestones and new project completion timelines that resulted in relief from the liquidated damages provisions. Of the remaining gross settlement, we collected $16 million during January 2017. As of December 31, 2016 , we have no claims revenue, and our percentage-of-completion project estimate includes a cumulative $25 million in approved change orders and $16 million of back charges. Our net billings in excess of costs as of December 31, 2016 were $45 million and are shown in the “Other Current Liabilities” on the Consolidated Balance Sheet. The amounts associated with contract change orders or claims are included in revenue only when they can be reliably estimated and their realization is reasonably assured. During 2015 , we recognized estimated project losses of $153 million related to our long-term early production facility construction contracts in Iraq accounted for under the percentage-of-completion method. Total estimated losses on these loss projects were $532 million at December 31, 2015. As of December 31, 2015 , our percentage-of-completion project estimates include $116 million of claims revenue and $28 million of back charges. During 2015 , an additional $32 million of claims revenue was included in our project estimates. Our costs in excess of billings as of December 31, 2015 were $6 million and are shown in the “Other Current Assets” on our Consolidated Balance Sheets . We also had a variety of unapproved contract change orders or claims that are not included in our revenues as of December 31, 2015 . The amounts associated with these contract change orders or claims are included in revenue only when they can be reliably estimated and their realization is reasonably assured. During 2014 , we recognized estimated project losses of $72 million related to our long-term early production facility construction contracts in Iraq accounted for under the percentage-of-completion method. Total estimated losses on these projects were $379 million at December 31, 2014 . As of December 31, 2014 , our percentage-of-completion project estimates include $90 million of claims revenue and $24 million of back charges. Our costs in excess of billings as of December 31, 2014 were $128 million and are shown in the “Other Current Assets” on the balance sheet. We had a variety of unapproved contract change orders or claims that were not included in our revenues as of December 31, 2014 . During 2014 , an additional $80 million of claims revenue was included in our project estimates and $26 million of our prior claims were approved.

Accounts Receivable Factoring	Accounts Receivable Factoring and Other Receivables From time to time, we participate in factoring arrangements to sell accounts receivable to third-party financial institutions. In 2016 , we sold accounts receivables of $156 million , received cash totaling $154 million and recognized a loss of $0.7 million . In 2015 , we sold accounts receivables of $78 million , received cash totaling $77 million and recognized a loss of $0.2 million . Our factoring transactions were recognized as sales, and the proceeds are included as operating cash flows in our Consolidated Statements of Cash Flows . We did not sell any accounts receivable during 2014. During the second quarter of 2016, we accepted a note with a face value of $120 million from PDVSA in exchange for $120 million in net trade receivables. The note had a three year term at a 6.5% stated interest rate. We carried the note at lower of cost or fair value and recognized a loss in the second quarter of 2016 of $84 million to adjust the note to fair value. In the fourth quarter of 2016, we sold the economic rights in the note receivable for $44 million and recognized a gain of $8 million .

During 2016 , 2015 and 2014 , we recognized inventory charges, including excess and obsolete inventory charges totaling $252 million , $186 million and $113 million , respectively. These charges were largely attributable to downturn in the oil and gas industry, where certain inventory has been deemed commercially unviable or technologically obsolete considering current and future demand.

Property, Plant and Equipment [Abstract]
Long-lived and Other Asset Impairments	Long-Lived Asset Impairments During the third quarter of 2016, we recognized long-lived asset impairment charges of $436 million , of which $388 million was related to product line PP&E impairments and $48 million was related to the impairment of intangible assets. The PP&E impairment charges were related to our MENA/Asia Pacific Pressure Pumping and North America Well Construction, Drilling Services and Secure Drilling Service product lines. These impairment charges were attributed to the following segments: $235 million in North America, $109 million in MENA/Asia Pacific, $12 million in Europe/SSA/Russia, $16 million in Latin America and $16 million in Land Drilling Rigs. The intangible asset charge is related to the Well Construction and Completions businesses with $35 million attributable to the North America segment and $13 million related the Europe/SSA/Russia segment. The impairments were due to the prolonged downturn in the oil and gas industry, whose recovery in the third quarter was not as strong as expected and whose recovery in the fourth quarter of 2016 and in 2017 was and is expected to be slower than had previously been anticipated. The change in the expectations of the market’s recovery, in addition to successive negative operating cash flows in certain asset groups represented an indicator that those assets will no longer be recoverable over their remaining useful lives. See “ Note 14 – Fair Value of Financial Instruments, Assets and Equity Investments ” for additional information regarding the fair value determination used in the impairment calculation. We recognized total long-lived impairment charges of $638 million in 2015 due to the continued weakness in crude oil prices contributing to lower exploration and production spending and a decline in the utilization of our assets. The decline in oil prices and its impact on demand represented a significant adverse change in the business climate and an indication that these long-lived assets may not be recoverable. Based on the presence of impairment indicators, we performed an analysis of these asset groups and recorded long-lived asset impairment charges to adjust the assets to fair value. During 2015, we recognized long-lived asset impairment charges of $124 million for pressure pumping assets in our North America segment, $259 million for equipment in our drilling tools, pressure pumping and wireline assets in our North America segment and $255 million related to assets for our Land Drilling Rigs segment. The fair value of our drilling tools, pressure pumping, and wireline assets were estimated using a combination of the income approach, the cost approach, and the market approach. See “ Note 14 – Fair Value of Financial Instruments, Assets and Equity Investments ” for additional information regarding the fair value determination. In the fourth quarter of 2014, a significant decline in crude oil prices contributed to lower anticipated exploration and production spending and a decline in the anticipated utilization of our drilling rig fleet. Based on the impairment indicators noted we performed an analysis of our drilling rig fleet and recorded long-lived asset impairment charges of $352 million to adjust the assets of our Land Drilling Rig business to fair value. The impairment charges included the impairment of our drilling rigs and certain related intangible assets. To determine the fair value of these assets we utilized an income approach. In July 2014, we completed the sale of our rig operations in Russia and Venezuela. We expected the sale would significantly impact the revenues and results of operations of our Russia reporting unit. As a result of our commitment to sell, we recorded a $143 million long-lived assets impairment charge during the second quarter of 2014.

Goodwill	Goodwill In 2016 and 2015, our annual goodwill impairment test indicated that goodwill was not impaired. In 2014, our annual goodwill impairment test indicated that the goodwill of the Land Drilling Rigs reporting units in Latin America , Europe and Asia Pacific was impaired. The results of our “step-one” analysis were accompanied by other indicators in the form of a decline in the anticipated utilization rates for our drilling rig fleet. Responsive to the impairment indicators noted, we performed a “step two” analysis, comparing the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. The “step two” analysis indicated that the goodwill for these reporting units was fully impaired and we recognized an impairment loss of $40 million related to Land Drilling Rigs segment in Latin America, Europe and Asia Pacific. In addition, during the second quarter of 2014, we engaged in negotiations to sell our land drilling and workover operations in Russia and Venezuela, and we subsequently entered into an agreement to sell the business in July 2014. During this time frame we expected the sale would significantly impact the revenues and results of operations of our Russia reporting unit, and consequently, we considered the associated circumstances to assess whether an event or change had occurred that, more likely than not, reduced the fair value of our reporting units below their carrying amount. We concluded that the planned sale represented an indicator of impairment, and we prepared the analysis necessary to identify the potential impairment and recognize any necessary impairment loss. The analysis indicated that the goodwill for the Russia reporting unit was impaired, and we recognized a goodwill impairment loss of $121 million , $95 million of which pertained to goodwill that had been reclassified during 2014 into current assets held for sale. See “ Note 2 – Business Combinations and Divestitures ” for additional information regarding the non-cash impairment charges to our assets held for sale. The changes in the carrying amount of goodwill by reportable segment for the two years ended December 31, 2016 and 2015 , were as follows: (Dollars in millions) North America MENA/ Asia Pacific Europe/ SSA/ Russia Latin America Total Balance at December 31, 2014 $ 1,896 $ 195 $ 623 $ 297 $ 3,011 Acquisitions 3 — — — 3 Purchase price and other adjustments — 1 — — 1 Foreign currency translation (143 ) (6 ) (50 ) (13 ) (212 ) Balance at December 31, 2015 $ 1,756 $ 190 $ 573 $ 284 $ 2,803 Foreign currency translation 21 (1 ) (30 ) 4 (6 ) Balance at December 31, 2016 $ 1,777 $ 189 $ 543 $ 288 $ 2,797

Short-term Borrowings and Current Portion of Long-term Debt	Our short-term borrowings and current portion of long-term debt consists of the followings: December 31, (Dollars in millions) 2016 2015 Revolving credit facility — 967 Other short-term bank loans 2 214 Total short-term borrowings 2 1,181 Current portion of long-term debt 177 401 Short-term borrowings and current portion of long-term debt $ 179 $ 1,582 Weighted average interest rate on short-term borrowings outstanding at end of year 0.7 % 2.7 % Revolving Credit Facility and Secured Term Loan Agreement We have a revolving credit facility (the “Revolving Credit Agreement”) in the amount of $1.38 billion and a $425 million secured term loan agreement (the “Term Loan Agreement” and collectively with the Revolving Credit Agreement, the “Credit Agreements”). For lenders that extended their commitments (“extending lenders”), the Revolving Credit Agreement matures in July of 2019. For lenders that did not extend their commitments (such lenders, representing $229 million , the “non-extending lenders”), the Revolving Credit Agreement matures in July of 2017. The Term Loan Agreement matures on July of 2020, and beginning September 30, 2016, a principal repayment of $12.5 million is required on the last day of each quarter. At December 31, 2016 , we had $1.3 billion available for borrowing under our Revolving Credit Agreement and there were $63 million in outstanding letters of credit. Loans under the Credit Agreements are subject to varying rates of interest based on whether the loan is a Eurodollar loan or an alternate base rate loan. We also incur a quarterly facility fee on the amount of the Revolving Credit Agreement. See “ Note 13 – Long-term Debt ”, for information related to interest rate applicable for the Term Loan Agreement. Eurodollar Loans. Eurodollar loans bear interest at the Eurodollar rate, which is LIBOR, plus the applicable margin. The applicable margin for Eurodollar loans under the Revolving Credit Agreement depends on whether the lender is an extending lender or a non-extending lender. For non-extending lenders, the applicable margin under the Revolving Credit Agreement ranges from 0.75% to 1.925% depending on our credit rating, and for extending lenders under the Revolving Credit Agreement the applicable margin ranges from 1.925% to 3.7% depending on our leverage ratio. Alternate Base Rate Loans. Alternate base rate loans bear interest at the alternate base rate plus the applicable margin. The applicable margin for alternate base rate loans under the Revolving Credit Agreement depends on whether the lender is an extending lender or a non-extending lender. For non-extending lenders, the applicable margin under the Revolving Credit Agreement ranges from 0% to 0.925% depending on our credit rating, and for extending lenders the applicable margin under the Revolving Credit Agreement ranges from 0.925% to 2.7% depending on our leverage ratio. For the year ended December 31, 2016 , the interest rate for the Revolving Credit Agreement was LIBOR plus a margin rate of 1.925% . See “ Note 13 – Long-term Debt ” for the interest rate details for the Term Loan Agreement. Borrowings under our Revolving Credit Agreement may be repaid from time to time without penalty. Obligations under the Term Loan Agreement are secured by substantially all of our assets. In addition, obligations under the Credit Agreements are guaranteed by a material portion of our subsidiaries. Our Credit Agreements contain covenants including, among others, the following: • a prohibition against incurring debt, subject to permitted exceptions; • a restriction on creating liens on our assets and the assets of our operating subsidiaries, subject to permitted exceptions; • restrictions on mergers or asset dispositions; • restrictions on use of proceeds, investments, transactions with affiliates, or change of principal business; and • maintenance of the following financial covenants: 1) Leverage ratio of no greater than 3.0 to 1 through December 31, 2016 and 2.5 to 1 thereafter until maturity. This ratio measures our indebtedness guaranteed by subsidiaries under the Credit Agreements and other guaranteed facilities to the trailing four quarters consolidated adjusted earnings before interest, taxes, depreciation, amortization and other specified charges (“EBITDA”); 2) Leverage and letters of credit ratio of no greater than 4.0 to 1 on or before December 31, 2016 and 3.5 to 1 thereafter calculated as our indebtedness guaranteed by subsidiaries under the Credit Agreements and other guaranteed facilities and all letters of credit to the trailing four quarters consolidated adjusted EBITDA; and 3) Asset coverage ratio of at least 4.0 to 1, which is calculated as our asset value to indebtedness guaranteed by subsidiaries under the Credit Agreements and other guaranteed facilities. Our Credit Agreements contain customary events of default, including our failure to comply with the financial covenants described above. As of December 31, 2016 , we were in compliance with these financial covenants. On July 19, 2016, we amended these facilities to make minor changes and amendments to certain collateral provisions, negative covenants and related definitions, and to add an accordion feature to permit new and existing lenders to add up to a maximum of $250 million in additional commitments. Other Short-Term Borrowings and Other Debt Activity We have short-term borrowings with various domestic and international institutions pursuant to uncommitted credit facilities. At December 31, 2016 , we had $2 million in short-term borrowings under these arrangements. In 2016, we repaid $180 million , with a LIBOR-based weighted average interest rate of 1.95% , borrowed under a credit agreement that matured in the first half of 2016. In addition, we had $450 million of letters of credit under various uncommitted facilities and $54 million of surety bonds, primarily performance bonds, issued by financial sureties against an indemnification from us at December 31, 2016 . At December 31, 2016 , the current portion of long-term debt was primarily related to our 6.35% Senior Notes due 2017 and the current portion of our secured term loan and capital leases. Our 5.50% senior notes with a principal balance of $350 million were repaid in February 2016. 364-Day Term Loan Facility On April 9, 2015, we repaid the $175 million balance of our $400 million , 364 -day term loan facility with a syndicate of banks. Previously in 2014, proceeds from this 364 -day term loan facility were used to refinance our prior 364 -day term loan facility and had substantially similar terms and conditions to our prior 364 -day term loan facility.

Fair Value of Financial Instruments	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments, Assets and Equity Investments Financial Instruments Measured and Recognized at Fair Value We estimate fair value at a price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market for the asset or liability. Our valuation techniques require inputs that we categorize using a three level hierarchy, from highest to lowest level of observable inputs. Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 inputs are quoted prices or other market data for similar assets and liabilities in active markets, or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based upon our own judgment and assumptions used to measure assets and liabilities at fair value. Classification of a financial asset or liability within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement. Other than the contingent consideration discussed in “ Note 2 – Business Combinations and Divestitures ” and our derivative instruments discussed in “ Note 15 – Derivative Instruments ,” we had no assets or liabilities measured and recognized at fair value on a recurring basis at December 31, 2016 and 2015 . Fair Value of Other Financial Instruments Our other financial instruments include cash and cash equivalents, accounts receivable, accounts payable, short-term borrowings and long-term debt. The carrying value of our cash and cash equivalents, accounts receivable, accounts payable, short-term borrowings approximates their fair value due to their short maturities. These short-term borrowings are classified as Level 2 in the fair value hierarchy. The fair value of our long-term debt fluctuates with changes in applicable interest rates among other factors. Fair value will generally exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued and will generally be less than the carrying value when the market rate is greater than the interest rate at which the debt was originally issued. The fair value of our long-term debt is classified as Level 2 in the fair value hierarchy and is established based on observable inputs in less active markets. The fair value and carrying value of our senior notes were as follows: December 31, (Dollars in millions) 2016 2015 Fair value $ 6,739 $ 5,095 Carrying value 7,028 6,099 Non-recurring Fair Value Measurements - Impairments During the third quarter of 2016, long-lived assets were impaired and written down to their estimated fair values. The Level 3 fair values of the long-lived assets were determined using either an income approach or a market approach. The unobservable inputs to the income approach included the assets’ estimated future cash flows and estimates of discount rates commensurate with the assets’ risks. The market approach considered unobservable estimates of market sales values, which in most cases was a scrap of salvage value estimate. During the second quarter of 2016, we adjusted the note from PDVSA to its estimated fair value. The Level 3 fair value was estimated based on unobservable pricing indications. During 2015, long-lived assets related to pressure pumping, drilling tools, wireline, and land drilling rigs were impaired and written down to their estimated fair values. The level 3 fair values of the long-lived assets were determined using a combination of the income approach, the cost approach and the market approach, which used inputs that included replacement costs (unobservable), physical deterioration estimates (unobservable), projections of estimated future operating cash flows (unobservable), discount rates for the applicable assets and market sales data for comparable assets. Also during 2015, an equity method investment was impaired and written down to its fair value. The equity investment level 3 fair value was determined using an income based approach utilizing estimates of future cash flow, discount rate, long-term growth rate, and marketability discount, all of which were unobservable. During the second quarter of 2014, long-lived assets in the rig operations in Russia and Venezuela and goodwill for the Russia reporting unit were impaired and written down to their estimated fair values. The level 3 fair value of the long-lived assets in the rig operations was determined using the market approach that considered the estimated sales price of those businesses. The goodwill level 3 fair value was determined using a combination of the income and market approaches with observable inputs that consisted of earnings multiples and unobservable inputs that included estimates of future cash flows, discount rate, long-term growth rate, and control premiums. During the fourth quarter of 2015, we impaired to the fair values of certain land drilling rigs and related intangible assets. The level 3 fair values were determined using an income approach that considered the remaining estimated cash flows of the associated assets, which were unobservable.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments From time to time, we may enter into derivative financial instrument transactions to manage or reduce our market risk. We manage our debt portfolio to achieve an overall desired position of fixed and floating rates, and we may employ interest rate swaps as a tool to achieve that goal. We enter into foreign currency forward contracts and cross-currency swap contracts to economically hedge our exposure to fluctuations in various foreign currencies. The major risks from interest rate derivatives include changes in the interest rates affecting the fair value of such instruments, potential increases in interest expense due to market increases in floating interest rates, changes in foreign exchange rates and the creditworthiness of the counterparties in such transactions. We monitor the creditworthiness of our counterparties, which are multinational commercial banks. The fair values of all our outstanding derivative instruments are determined using a model with Level 2 inputs including quoted market prices for contracts with similar terms and maturity dates. Warrant During the fourth quarter of 2016, in conjunction with the issuance of 84.5 million shares of common stock, we also issued a warrant that gives the holder the option to acquire an additional 84.5 million shares. The exercise price on the warrant is $6.43 per share and is exercisable any time prior to May 21, 2019. The warrant is classified as a liability and carried at fair value with changes in its fair value reported through earnings. The warrant participates in dividends and other distributions as if the shares subject to the warrants were outstanding. In addition, the warrant permits early redemption due to change in control. The warrant fair value is considered a Level 3 valuation and is estimated using a combination of the Black Scholes option valuation model and Monte-Carlo simulation. Inputs to these models include Weatherford’s stock price, volatility and the risk free interest rate. The valuation also considers the probabilities of future stock issuances and anticipated issuance discounts, which are considered Level 3 inputs. The fair value of the warrant was $172 million on its issuance date of November 16, 2016 and $156 million on December 31, 2016 , generating an unrealized gain of $16 million . The warrant valuation would be negatively affected due to an increase in the likelihood of a future stock issuance. Fair Value Hedges We may use interest rate swaps to help mitigate exposures related to changes in the fair values of the fixed-rate debt. The interest rate swap is recorded at fair value with changes in fair value recorded in earnings. The carrying value of fixed-rate debt is also adjusted for changes in interest rates, with the changes in value recorded in earnings. After termination of the hedge, any discount or premium on the fixed-rate debt is amortized to interest expense over the remaining term of the debt. As of December 31, 2016 and 2015 , we had net unamortized premiums on fixed-rate debt of $7 million and $23 million , respectively, associated with fair value hedge swap terminations. These premiums are being amortized over the remaining term of the originally hedged debt as a reduction of interest expense which are included in the line captioned “Interest Expense, Net” on the accompanying Consolidated Statements of Operations. Cash Flow Hedges In 2008, we entered into interest rate derivative instruments to hedge projected exposures to interest rates in anticipation of a debt offering. These hedges were terminated at the time of the issuance of the debt, and the associated loss is being amortized from Accumulated Other Comprehensive Loss to interest expense over the remaining term of the debt. As of December 31, 2016 and 2015 , we had net unamortized losses of $9 million and $10 million , respectively, associated with our cash flow hedge terminations. Foreign Currency Derivative Instruments At December 31, 2016 and 2015 , we had outstanding foreign currency forward contracts with total notional amounts aggregating $1.6 billion and $1.7 billion , respectively. The notional amounts of our foreign currency forward contracts do not generally represent amounts exchanged by the parties and thus are not a measure of the cash requirements related to these contracts or of any possible loss exposure. The amounts actually exchanged are calculated by reference to the notional amounts and by other terms of the derivative contracts, such as exchange rates. Our foreign currency forward contracts and cross-currency swaps are not designated as hedges, and the changes in fair value of the contracts are recorded in current earnings each period in the line captioned “ Other Income (Expense), Net ” on the accompanying Consolidated Statements of Operations . The total estimated fair values of these foreign currency forward contracts and amounts receivable or owed associated with closed foreign currency contracts and the total estimated fair value of our cross-currency contracts are as follows: December 31, (Dollars in millions) 2016 2015 Classifications Derivative assets not designated as hedges: Foreign currency forward contracts $ 7 $ 5 Other Current Assets Derivative liabilities not designated as hedges: Foreign currency forward contracts (14 ) (14 ) Other Current Liabilities Warrant on Weatherford Shares (156 ) — Other Non-current Liabilities The amount of derivative instruments’ gain or (loss) on the Consolidated Statements of Operations is in the table below.

On June 17, 2014, we completed the change in our place of incorporation from Switzerland to Ireland, whereby Weatherford Ireland became the new public holding company and the parent of the Weatherford group of companies, pursuant to which each registered share of Weatherford Switzerland was exchanged as consideration for the allotment of one ordinary share of Weatherford Ireland (excluding shares held by, or for the benefit of, Weatherford Switzerland or any of its subsidiaries). The Weatherford Switzerland shares were then cancelled. Weatherford Ireland issued ordinary shares with a par value of $0.001 per share. In conjunction with the redomestication, the shares held by our executive deferred compensation plan were sold and the remaining treasury shares were cancelled. Accumulated Other Comprehensive Loss The following table presents the changes in our accumulated other comprehensive loss by component for the year ended December 31, 2016 and 2015 : (Dollars in millions) Currency Translation Adjustment Defined Benefit Pension Deferred Loss on Derivatives Total Balance at December 31, 2014 $ (813 ) $ (57 ) $ (11 ) $ (881 ) Other comprehensive (loss) income before reclassifications (789 ) 28 — (761 ) Reclassifications — — 1 1 Net activity (789 ) 28 1 (760 ) Balance at December 31, 2015 (1,602 ) (29 ) (10 ) (1,641 ) Other comprehensive (loss) income before reclassifications (12 ) 41 — 29 Reclassifications — 1 1 2 Net activity (12 ) 42 1 31 Balance at December 31, 2016 $ (1,614 ) $ 13 $ (9 ) $ (1,610 ) For the year ended December 31, 2016, the defined benefit pension component of other comprehensive income before reclassifications relates primarily to a net actuarial gain resulting from the revaluation of the pension obligation associated with our supplemental executive retirement plan. For the year ended December 31, 2015 , the defined benefit pension component of other comprehensive income before reclassifications relates primarily to a net actuarial gain resulting from the conversion of one of our international pension plans from a defined benefit plan to a defined contribution plan. In addition, other comprehensive income reflects the reclassification of our deferred loss on derivatives related to the early redemption of our senior notes. The reclassification from the currency translation adjustment component of other comprehensive income includes $90 million from the sale of our land drilling and workover rig operations in Russia and Venezuela and pipeline and specialty service businesses. This amount was recognized in the “ Gain on Sale of Businesses and Investments, Net ” line in our Consolidated Statements of Operations for the year ended December 31, 2014 .

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share for all periods presented equals net income divided by the weighted average number of our shares outstanding during the period including participating securities. Diluted earnings per share is computed by dividing net income by the weighted average number of our shares outstanding during the period including participating securities, adjusted for the dilutive effect of our stock options, restricted shares and performance units. The following discloses basic and diluted weighted average shares outstanding: Year Ended December 31, (Shares in millions) 2016 2015 2014 Basic and Diluted weighted average shares outstanding 887 779 777 Our basic and diluted weighted average shares outstanding for the years ended December 31, 2016 , 2015 and 2014 , are equivalent due to the net loss attributable to shareholders. Diluted weighted average shares outstanding for the years ended December 31, 2016 , 2015 and 2014 , exclude potential shares for stock options, restricted shares, performance units, exchangeable notes, warrants outstanding and the Employee Stock Purchase Plan (“ESPP”) as we have net losses for those periods and their inclusion would be anti-dilutive. The following table discloses the number of anti-dilutive shares excluded: Year Ended December 31, (Shares in millions) 2016 2015 2014 Anti-dilutive potential shares 104 3 5

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	Share-Based Compensation Incentive Plans Our incentive plans permit the grant of options, stock appreciation rights, RSAs, restricted share units (“RSUs”), performance share awards, performance unit awards (“PUs”), other share-based awards and cash-based awards to any employee, non-employee directors and other individual service providers or any affiliate. Compensation expense is recognized on a straight-line basis over the requisite service period for the separately vesting portion of each award. The provisions of each award vary based on the type of award granted and are determined by the Compensation Committee of our Board of Directors. Those awards, such as stock options that are based on a specific contractual term, will be granted with a term not to exceed 10 years . Upon grant of an RSA, the recipient has the rights of a shareholder, including but not limited to the right to vote such shares and the right to receive any dividends paid on such shares, but not the right to disposition prior to vesting. Recipients of RSU awards do not have the rights of a shareholder until such date as the shares are issued or transferred to the recipient. As of December 31, 2016 , approximately 25 million shares were available for grant under our incentive plans. Share-Based Compensation Expense We recognized the following share-based compensation expense during each of the years ended December 31, 2016 , 2015 and 2014 : Year Ended December 31, (Dollars in millions) 2016 2015 2014 Share-based compensation $ 87 $ 73 $ 56 Related tax (provision) benefit — 14 12 Options Stock options were granted with an exercise price equal to or greater than the fair market value of our shares as of the date of grant. We used the Black-Scholes option pricing model to determine the fair value of stock options awarded. The estimated fair value of our stock options was expensed over their vesting period, which was generally one to four years. There were no stock options granted during 2016 , 2015 or 2014 . The intrinsic value of stock options exercised during 2015 and 2014 was $15 million and $13 million , respectively. No stock options were exercised during 2016 . All options were fully vested. A summary of option activity for the year ended December 31, 2016 , is presented below: Options Weighted Average Exercise Price Weighted Average Remaining Term Aggregate Intrinsic Value (In thousands) (In thousands) Outstanding at December 31, 2015 2,503 $ 14.67 0.93 years $ 36 Exercised — — Expired (1,905 ) 15.32 Outstanding and Vested at December 31, 2016 598 12.59 0.91 years — Exercisable at December 31, 2016 — — 0.00 years — Restricted Share Awards and Restricted Share Units RSAs and RSUs vest based on continued employment, generally over a two to five -year period. The fair value of RSAs and RSUs is determined based on the closing price of our shares on the date of grant. The total fair value, less assumed forfeitures, is expensed over the vesting period. The weighted-average grant date fair value of RSAs and RSUs granted during the years ended December 31, 2016 , 2015 and 2014 was $6.20 , $11.94 and $18.98 , respectively. The total fair value of RSAs and RSUs vested during the years ended December 31, 2016 , 2015 and 2014 was $38 million , $37 million and $52 million , respectively. As of December 31, 2016 , there was $83 million of unrecognized compensation expense related to unvested RSAs and RSUs, which is expected to be recognized over a weighted average period of two years . A summary of RSA and RSU activity for the year ended December 31, 2016 is presented below: RSA Weighted Average Grant Date Fair Value RSU Weighted Average Grant Date Fair Value (In thousands) (In thousands) Non-Vested at December 31, 2015 871 $ 14.85 11,964 $ 12.94 Granted — — 8,142 6.20 Vested (625 ) 14.26 (5,833 ) 12.02 Forfeited (109 ) 14.95 (1,479 ) 12.26 Non-Vested at December 31, 2016 137 17.42 12,794 9.15 Performance Units The performance units we granted in 2016 and 2015 vest over three years and the performance units we granted prior to 2014 vest at the end of a three -year period assuming continued employment and the Company’s achievement of certain market-based performance goals. Depending on the performance levels achieved in relation to the predefined targets, shares may be issued for up to 200% of the units awarded. If the established performance goals are not met, the performance units will expire unvested and no shares will be issued. The grant date fair value of the performance units we have granted was determined through use of the Monte Carlo simulation method . The assumptions used in the Monte Carlo simulation during the year ended December 31, 2016 , included a risk-free rate of 0.80% , volatility of 68.0% and a zero dividend yield. The weighted-average grant date fair value of the performance units we granted during the years ended December 31, 2016 , 2015 and 2014 was $5.11 , $10.45 and $14.31 , respectively. For the years ended December 31, 2016 and 2015 , we did not issue any shares. The total fair value of shares issued in connection with performance units during the years ended December 31, 2014 was $11 million . For the year ended December 31, 2014, 541 thousand shares of stock were issued for the performance units related to the departure of certain former executive officers. As of December 31, 2016 , there was $7 million of unrecognized compensation expense related to performance units, which is expected to be recognized over a weighted average period of two years . A summary of performance unit activity for the year ended December 31, 2016 , is presented below: Performance Units Weighted Average Grant Date Fair Value (In thousands) Non-vested at December 31, 2015 2,857 $ 11.17 Granted 2,112 5.11 Vested — — Forfeited (3,037 ) 9.56 Non-vested at December 31, 2016 1,932 7.08 Employee Stock Purchase Plan In June 2016, our shareholders adopted our ESPP and approved 12 million shares to be reserved for issuance under the plan. The ESPP permits eligible employees to make payroll deductions to purchase Weatherford stock. Each offering period has a six-month duration beginning on either March 1 or September 1. Shares are purchased at 90% of the lower of the closing price for our common stock on the first or last day of the offering period. As the inaugural offering period is still in progress, no shares have been issued under the ESPP as of December 31, 2016.

Retirement and Employee Benefit

Retirement and Employee Benefit Plans	12 Months Ended

Compensation and Retirement Disclosure [Abstract]
Retirement and Employee Benefit Plans	Retirement and Employee Benefit Plans We have defined contribution plans covering certain employees. Contribution expenses related to these plans totaled $30 million , $66 million and $79 million in 2016 , 2015 and 2014 , respectively. The decrease in employer contributions in 2016 compared to 2015 relates primarily to the suspension of employer matching contributions to our U.S. 401(k) savings plan and other contribution plans sponsored by the Company. We have defined benefit pension and other post-retirement benefit plans covering certain U.S. and international employees. Plan benefits are generally based on factors such as age, compensation levels and years of service. Early in 2015, we converted one of our larger defined benefit plans to a defined contribution plan. As a result, amounts shown for 2015 are significantly lower than previous years. Net periodic benefit cost related to these plans totaled $9 million , $9 million and $18 million in 2016 , 2015 and 2014 , respectively. The projected benefit obligations on a consolidated basis were $205 million and $245 million as of December 31, 2016 and 2015 , respectively. The decrease year over year is due primarily to a net actuarial gain associated with our supplemental executive retirement plan. The fair values of plan assets on a consolidated basis (determined primarily using Level 2 inputs) were $118 million and $121 million as of December 31, 2016 and 2015 , respectively. As of December 31, 2016 , the net underfunded obligation was primarily recorded within Other Non-current Liabilities with approximately $22 million recorded in Accrued Salaries and Benefits. As of December 31, 2015, the net underfunded obligation was substantially all recorded within Other Non-current Liabilities . Additionally, consolidated pre-tax amounts in accumulated other comprehensive income that have not yet been recognized as components of net periodic benefit cost were income of $3 million and loss of $38 million as of December 31, 2016 and 2015 , respectively. The increase in other comprehensive income (loss) year over year is due primarily to the net actuarial gain mentioned above. The weighted average assumption rates used for benefit obligations were as follows: Year Ended December 31, 2016 2015 Discount rate: United States plans 1.00% - 4.00% 1.00% - 4.25% International plans 1.90% - 7.50% 2.30% - 8.00% Rate of compensation increase: United States plans — — International plans 2.00% - 3.50% 2.00% - 3.20% During 2016 and 2015 , we made contributions and paid direct benefits of $6 million and $6 million , respectively, in connection with our defined benefit pension and other post-retirement benefit plans. In 2017 , we expect to fund approximately $3 million with cash and $22 million with shares related to those plans. In addition, we expect to recognize net gains of approximately $40 million in net periodic benefit cost in conjunction with amortization associated primarily with our supplemental executive retirement plan.

Income Taxes

Income Taxes	12 Months Ended

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes We are exempt from Swiss cantonal and communal tax on income derived outside Switzerland, and we are also granted participation relief from Swiss federal tax for qualifying dividend income and capital gains related to the sale of qualifying investments in subsidiaries. We expect that the participation relief will result in a full exemption of participation income from Swiss federal income tax. We provide for income taxes based on the laws and rates in effect in the countries in which operations are conducted, or in which we or our subsidiaries are considered resident for income tax purposes. The relationship between our pre-tax income or loss and our income tax provision or benefit varies from period to period as a result of various factors which include changes in total pre-tax income or loss, the jurisdictions in which our income is earned, the tax laws in those jurisdictions and in our operating structure. Our income tax (provision) benefit from continuing operations consisted of the following: Year Ended December 31, (Dollars in millions) 2016 2015 2014 Total Current Provision $ (115 ) $ (303 ) $ (350 ) Total Deferred (Provision) Benefit (381 ) 448 66 (Provision) Benefit for Income Taxes $ (496 ) $ 145 $ (284 ) Weatherford records deferred tax assets for net operating losses and temporary differences between the book and tax basis of assets and liabilities that are expected to produce tax deductions in future periods. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which those deferred tax assets would be deductible. The Company assesses the realizability of its deferred tax assets each period by considering whether it is more likely than not that all or a portion of the deferred tax assets will not be realized. The Company considers all available evidence (both positive and negative) when determining whether a valuation allowance is required. The Company evaluated possible sources of taxable income that may be available to realize the benefit of deferred tax assets, including projected future taxable income, the reversal of existing temporary differences, taxable income in carryback years and available tax planning strategies in making this assessment. The realizability of the deferred tax assets is dependent upon judgments and assumptions inherent in the determination of future taxable income, including factors such as future operation conditions (particularly as related to prevailing oil prices and market demand for our products and services). Operations in the United States and other jurisdictions continue to experience losses due to the prolonged downturn in the demand for oil field services. Our expectations regarding the recovery were and are more measured due to the difficulties in obtaining pricing increases from our customers and a slower recovery in the U.S. land market. Also, the Company recorded significant long-lived asset impairments and established allowances for inventory and other assets in the third quarter of 2016. As a result of the historical and projected future losses, and limited objective positive evidence to overcome negative evidence, the Company concluded that it needed to record a valuation allowance of $526 million in the third quarter of 2016 against certain previously benefited deferred tax assets since it cannot support that it is more likely than not that the deferred tax assets will be realized. The valuation allowance primarily relates to operations in the United States. The Company will continue to evaluate whether valuation allowances are needed in future reporting periods. Valuation allowances will remain until the Company can determine that net deferred tax assets are more likely than not to be realized. In the event that the Company were to determine that it would be able to realize the deferred income tax assets in the future as a result of significant improvement in earnings as a result of market conditions, the Company would adjust the valuation allowance, reducing the provision for income taxes in the period of such adjustment. The difference between the income tax (provision) benefit at the Swiss federal income tax rate and the income tax (provision) benefit attributable to “ Loss Before Income Taxes ” for each of the three years ended December 31, 2016 , 2015 and 2014 is analyzed below: Year Ended December 31, (Dollars in millions) 2016 2015 2014 Swiss federal income tax rate at 7.83% $ 225 $ 164 $ 20 Tax on operating earnings subject to rates different than the Swiss federal income tax rate 319 411 (70 ) Tax on divestitures gains subject to different tax rate — — (109 ) Non-cash tax expense on distribution of subsidiary earnings (137 ) (265 ) — Change in valuation allowance (872 ) (159 ) (222 ) Change in uncertain tax positions (31 ) (6 ) 97 (Provision) Benefit for Income Taxes $ (496 ) $ 145 $ (284 ) Our income tax provision in 2016 was $496 million on a loss before income taxes of $2.9 billion . The primary component of the tax expense relates to the Company’s conclusion that certain deferred tax assets that had previously been benefited are not more likely than not to be realized. Our results for 2016 also include charges with no significant tax benefit principally related to $436 million of long-lived asset impairments, $219 million of excess and obsolete inventory charges, $140 million of settlement agreement charges, $41 million of currency devaluation related to the Angolan kwanza, $78 million of bond tender premium, and $76 million of PDVSA note receivable net adjustment, $62 million in accounts receivable reserves and write-offs, and $114 million in pressure pumping related charges. In addition, we recorded $137 million for a non-cash tax expense related to an internal restructuring of subsidiaries. In 2015, we had a tax benefit of $145 million on a loss before income taxes of $2.1 billion . The tax benefit was favorably impacted by a U.S. loss, which included restructuring, impairment charges and a worthless stock deduction. Our results for 2015 include $255 million of Land Drilling Rig impairment charges, $232 million of restructuring charges, $116 million of litigation settlements, $153 million of legacy project losses, $85 million of currency devaluation and related losses and $25 million of equity investment impairment, all with no significant tax benefit. In addition, we recorded a tax charge of $265 million for a non-cash tax expense on distribution of subsidiary earnings. In 2014, we had a tax provision of $284 million on a loss before income taxes of $255 million . Our results for 2014 include a $161 million goodwill impairment charge, a $245 million loss due to the devaluation of Venezuela bolivar and $72 million of project losses related to our early production facility contracts in Iraq, all of which provided no tax benefit. In addition, we incurred a $495 million long-lived assets impairments charge, with limited tax benefit. During 2014, we also sold our land drilling and workover rig operations in Russia and Venezuela, pipeline and specialty services business, engineered chemistry, Integrity drilling fluids business and our equity investment in Proserv for a total gain of approximately $349 million . Deferred tax assets and liabilities are recognized for the estimated future tax effects of temporary differences between the tax basis of an asset or liability and its reported amount in the Consolidated Financial Statements . The measurement of deferred tax assets and liabilities is based on enacted tax laws and rates currently in effect in each of the jurisdictions in which we have operations. For 2015, deferred tax assets and liabilities are classified as current or non-current according to the classification of the related asset or liability for financial reporting. For 2016, we adopted ASU 2015-17 and classify net deferred tax assets and liabilities as non-current. The components of the net deferred tax asset (liability) attributable to continuing operations were as follows: December 31, (Dollars in millions) 2016 2015 Net operating losses carryforwards $ 1,258 $ 972 Accrued liabilities and reserves 200 190 Tax credit carryforwards 102 102 Employee benefits 34 52 Inventory 75 64 Other differences between financial and tax basis 252 267 Valuation allowance (1,738 ) (868 ) Total deferred tax assets 183 779 Deferred tax liabilities: Property, plant and equipment (13 ) (53 ) Intangible assets (212 ) (209 ) Deferred Income (9 ) (21 ) Undistributed Subsidiary Earnings — (179 ) Other differences between financial and tax basis (25 ) (12 ) Total deferred tax liabilities (259 ) (474 ) Net deferred tax asset (liability) $ (76 ) $ 305 The overall increase in the valuation allowance in 2016 is primarily attributable to the establishment of a valuation allowance against current year net operating losses (“NOLs”) and beginning-of-year deferred tax assets in the United States, Brazil, and Colombia. The valuation allowance increase for 2015 is primarily attributable to the establishment of a valuation allowance against current year NOLs and tax credits in Mexico, Venezuela, and Iraq. Deferred income taxes generally have not been recognized on the cumulative undistributed earnings of our non-Swiss subsidiaries because they are considered to be indefinitely reinvested or they can be distributed on a tax free basis. Distribution of these earnings in the form of dividends or otherwise may result in a combination of income and withholding taxes payable in various countries. In 2015 the company reversed its indefinitely reinvested assertion on a portion of those earnings and recorded a non-cash tax charge of $265 million . In addition, during the third quarter of 2016 we recorded a tax charge of $137 million for a non-cash tax expense related to an internal restructuring of subsidiaries. These charges covered the tax expense on distributions of earnings made during the fourth quarter of 2016 from subsidiaries to the U.S. As of December 31, 2016, the pool of positive undistributed earnings of our non-Swiss subsidiaries that are considered indefinitely reinvested and may be subject to tax if distributed amounts to approximately $3.6 billion . Due to complexities in the tax laws and the manner of repatriation, it is not practicable to estimate the unrecognized amount of deferred income taxes and the related dividend withholding taxes associated with these undistributed earnings. At December 31, 2016 , we had approximately $4.5 billion of NOLs in various jurisdictions, $1.7 billion of which were generated by certain U.S. subsidiaries. Loss carryforwards, if not utilized, will mostly expire for U.S. subsidiaries from 2033 through 2036 and at various dates from 2017 through 2036 for non-U.S. subsidiaries. At December 31, 2016 , we had $102 million of tax credit carryovers, of which $82 million is for U.S. subsidiaries. The U.S. credits primarily consists of $30 million of research and development tax credit carryforwards which expire from 2018 through 2036 , and $52 million of foreign tax credit carryforwards which expire from 2017 through 2023 . A tabular reconciliation of the total amounts of uncertain tax positions at the beginning and end of the period is as follows: Year Ended December 31, (Dollars in millions) 2016 2015 2014 Balance at beginning of year $ 195 $ 235 $ 289 Additions as a result of tax positions taken during a prior period 30 28 23 Reductions as a result of tax positions taken during a prior period (1 ) (9 ) (35 ) Additions as a result of tax positions taken during the current period 20 5 2 Reductions relating to settlements with taxing authorities (19 ) (46 ) (24 ) Reductions as a result of a lapse of the applicable statute of limitations (12 ) (7 ) (9 ) Foreign exchange effects (5 ) (11 ) (11 ) Balance at end of year $ 208 $ 195 $ 235 Substantially all of the uncertain tax positions, if recognized in future periods, would impact our effective tax rate. To the extent penalties and interest would be assessed on any underpayment of income tax, such amounts have been accrued and classified as a component of income tax expense and other non-current liabilities in the Consolidated Financial Statements in accordance with our accounting policy. We recorded an expense of $2 million , and a benefit of $4 million and $53 million of interest and penalty for the years ended December 31, 2016 , 2015 and 2014 , respectively. The amounts in the table above exclude cumulative accrued interest and penalties of $51 million , $50 million , and $58 million at December 31, 2016 , 2015 and 2014 , respectively, which are included in other liabilities. We are subject to income tax in many of the approximately 90 countries where we operate. As of December 31, 2016 , the following table summarizes the tax years that remain subject to examination for the major jurisdictions in which we operate: Canada 2008 - 2016 Mexico 2007 - 2016 Russia 2013 - 2016 Switzerland 2010 - 2016 United States 2010 - 2016 Venezuela 2010 - 2016 We are continuously under tax examination in various jurisdictions. We cannot predict the timing or outcome regarding resolution of these tax examinations or if they will have a material impact on our financial statements. We anticipate that it is reasonably possible that the amount of uncertain tax positions may decrease by up to $40 million in the next twelve months due to expiration of statutes of limitations, settlements and/or conclusions of tax examinations.

Disputes, Litigation and Contin

Disputes, Litigation and Contingencies	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Disputes, Litigation and Contingencies	Disputes, Litigation and Contingencies Shareholder Litigation In 2010, three shareholder derivative actions were filed, purportedly on behalf of the Company, asserting breach of duty and other claims against certain current and former officers and directors of the Company related to the United Nations oil-for-food program governing sales of goods into Iraq, the FCPA and trade sanctions related to the U.S. government investigations disclosed in our U.S. Securities and Exchange Commission (the “SEC”) filings since 2007. Those shareholder derivative cases were filed in Harris County, Texas state court and consolidated under the caption Neff v. Brady, et al. , No. 2010040764 (collectively referred to as the “ Neff Case”). Other shareholder demand letters covering the same subject matter were received by the Company in early 2014, and a fourth shareholder derivative action was filed, purportedly on behalf of the Company, also asserting breach of duty and other claims against certain current and former officers and directors of the Company related to the same subject matter as the Neff Case. That case, captioned Erste-Sparinvest KAG v. Duroc-Danner, et al., No. 201420933 (Harris County, Texas) was consolidated into the Neff Case in September 2014. A motion to dismiss was granted May 15, 2015 and an appeal, which remains pending, was filed on June 15, 2015. We cannot reliably predict the outcome of the appeal including the amount of any possible loss. If one or more negative outcomes were to occur relative to the Neff Case, the aggregate impact to our financial condition could be material. Securities Class Action Settlement On June 30, 2015, we signed a stipulation to settle a shareholder securities class action captioned Freedman v. Weatherford International Ltd., et al. , No. 1:12-cv-02121-LAK (S.D.N.Y.) for $120 million subject to notice to the class and court approval. The Freedman lawsuit had been filed in the U.S. District Court for the Southern District of New York in March 2012, and alleged that we and certain current and former officers of Weatherford violated the federal securities laws in connection with the restatements of the Company’s historical financial statements announced on February 21, 2012 and July 24, 2012. On November 4, 2015, the U.S. District Court for the Southern District of New York entered a final judgment and an order approving the settlement. Pursuant to the settlement, we were required to pay $120 million , which was partially funded by insurance proceeds. There was no admission of liability or fault by a party in connection with the settlement. We are pursuing reimbursement from our insurance carriers and recovered $19 million of the settlement amount, of which $4 million was recovered in 2016. On January 30, 2015, the U.S. District Court for the Southern District of New York approved the settlement of a purported shareholder securities class action captioned Dobina v. Weatherford International Ltd. , et al. , No. 1:11-cv-01646-LAK (S.D.N.Y.) for $53 million . The action named Weatherford and certain current and former officers as defendants. It alleged violation of the federal securities laws in connection with the material weakness in our internal controls over financial reporting for income taxes, and restatement of our historical financial statements announced in March 2011. The settlement was entirely funded by our insurers. There was no admission of liability or fault by any party in connection with the settlement. Shareholder Derivative Actions Settlement We signed an amended stipulation of settlement in November 2014 to resolve two shareholder derivative actions related to the Company’s restatement of its financial statements and material weakness in internal controls over financial reporting for income taxes. On June 24, 2015, the U.S. District Court for the Southern District of New York approved the settlement and entered final judgment in one of the two cases, Wandel v. Duroc-Danner, et al. , No. 1:12-cv-01305-LAK. By agreement with the plaintiffs, a substantially identical shareholder derivative case, Iron Workers Mid-South Pension Fund v. Duroc-Danner, et al. , No. 201119822, pending in Harris County, Texas, state court was voluntarily dismissed with prejudice. The two cases, purportedly brought on behalf of the Company against certain current and former officers and directors, alleged breaches of duty related to our material weakness and restatements. The settlement included an agreed upon set of revised corporate procedures, no monetary payment by the defendants and an award of attorney’s fees and reimbursement of expenses for a total amount of $0.6 million for the plaintiff’s counsel, which we paid in July 2015. There was no admission of liability or fault by any party in connection with the settlement. U.S. Government and Internal Investigations The SEC and the U.S. Department of Justice (“DOJ”) were investigating certain accounting issues associated with the material weakness in our internal control over financial reporting for income taxes that was disclosed in a notification of late filing on Form 12b-25 filed on March 1, 2011 and in current reports on Form 8-K filed on February 21, 2012 and on July 24, 2012 and the subsequent restatements of our historical financial statements. During the first quarter 2016, we recorded a loss contingency in the amount of $65 million , and increased it to $140 million in the second quarter to reflect our best estimate of the potential settlement. As disclosed on the Form 8-K filed on September 27, 2016, the Company settled with the SEC without admitting or denying the findings of the SEC, by consenting to the entry of an administrative order that requires the Company to cease and desist from committing or causing any violations and any future violations of the anti-fraud provisions of the Securities Act of 1933, and the anti-fraud, reporting, books and records, and internal controls provisions of the Securities Exchange Act of 1934, and the rules promulgated thereunder. As part of the terms of the SEC settlement, the Company agreed to pay a total civil monetary penalty of $140 million , with 50 million due within 21 days from the settlement agreement and three installments of $30 million due within 120 , 240 and 360 days. In addition, certain reports and certifications must be delivered to the SEC in the following two years regarding our tax internal controls. The first installment of $50 million was paid during the fourth quarter of 2016. The second installment of $30 million was paid in January of 2017. Other Disputes and Litigation In August 2016, after a bench trial in Harris County, Texas, the court entered a judgment in favor of Spitzer Industries, Inc. (“Spitzer”) in connection with Spitzer’s fabrication work on a two mobile capture vessels used in the cleanup of marine oil spills. The Company has taken a reserve in the full amount of the judgment and has initiated an appeal of the judgment to the First Court of Appeals in Houston, Texas. Additionally, we are aware of various disputes and potential claims and are a party in various litigation involving claims against us, including as a defendant in various employment claims alleging our failure to pay certain classes of workers overtime in compliance with the Fair Labor Standards Act for which an agreement was reached and settled during 2016. Some of these disputes and claims are covered by insurance. For claims, disputes and pending litigation in which we believe a negative outcome is probable and a loss can be reasonably estimated, we have recorded a liability for the expected loss. These liabilities are immaterial to our financial condition and results of operations. In addition we have certain claims, disputes and pending litigation for which we do not believe a negative outcome is probable or for which we can only estimate a range of liability. It is possible, however, that an unexpected judgment could be rendered against us, or we could decide to resolve a case or cases, that would result in liability that could be uninsured and beyond the amounts we currently have reserved and in some cases those losses could be material. If one or more negative outcomes were to occur relative to these matters, the aggregate impact to our financial condition could be material. Accrued litigation and settlements recorded in “Other Current Liabilities” on the accompanying Consolidated Balance Sheets as of December 31, 2016 and 2015 were $181 million and $53 million , respectively. The accrued litigation balance as of December 31, 2016 included the remaining SEC settlement obligation of $90 million .

Segment Reporting [Abstract]
Segment Information	Segment Information Reporting Segments We have a total of five reportable segments which are North America, MENA/Asia Pacific, Europe/SSA/Russia, Latin America and Land Drilling Rigs . The operational performance of our segments is reviewed and managed primarily on a geographic basis, and we report the regional segments as separate, distinct reporting segments. In addition, our Land Drilling Rigs business, which we intend to divest, is reviewed and managed apart from our regional segments. Our corporate and other expenses that do not individually meet the criteria for segment reporting continue to be reported separately as Corporate and Research and Development. Each business reflects a reportable segment led by separate business segment management that reports directly or indirectly to our chief operating decision maker (“CODM”). Our CODM assesses performance and allocates resources on the basis of the five reportable segments. Financial information by segment is summarized below. Revenues are attributable to countries based on the ultimate destination of the sale of products or performance of services. The accounting policies of the segments are the same as those described in “ Note 1 – Summary of Significant Accounting Policies ”.

Summary of Significant Accoun35

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Principles of Consolidation	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. All material intercompany accounts and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year presentation related to the adoption of new accounting standards. Net income and shareholders’ equity were not affected by these reclassifications. See subsection entitled “New Accounting Pronouncements” for additional details. Investments in affiliates in which we exercise significant influence over operating and financial policies are accounted for using the equity method. We recognize equity in earnings of unconsolidated affiliates in Selling, General and Administration attributable to segments in our Consolidated Statements of Operations (see “ Note 11 – Equity Investments ”).
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts 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 market of inventories, equity investments, derivative financial instruments, intangible assets and goodwill, property, plant and equipment (“PP&E”), income taxes, percentage-of-completion 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.
Disputes, Litigation and Contingencies	Disputes, Litigation and Contingencies We accrue an estimate of the probable and estimable cost to resolve certain legal and investigation matters. For matters not deemed probable and reasonably estimable, we have not accrued any amounts in accordance with U.S. GAAP. Our contingent loss estimates are based upon an analysis of potential results, assuming a combination of probable litigation and settlement strategies. The accuracy of these estimates is impacted by the complexity of the associated issues.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments with original maturities of three months or less to be cash equivalents.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts We establish an allowance for doubtful accounts based on various factors including historical experience, the current aging status of our customer accounts, the financial condition of our customers and the business and political environment in which our customers operate. Provisions for doubtful accounts are recorded when it becomes probable that customer accounts are uncollectible.
Major Customers and Credit Risk	Major Customers and Credit Risk Substantially all of our customers are engaged in the energy industry. This concentration of customers may impact our overall exposure to credit risk, either positively or negatively, in that customers may be similarly affected by changes in economic and industry conditions. We perform on-going credit evaluations of our customers and do not generally require collateral in support of our trade receivables. We maintain allowances for potential credit losses, and actual losses have historically been within our expectations. International sales also present various risks, including risks of war, civil disturbances and governmental activities that may limit or disrupt markets, restrict the movement of funds, or result in the deprivation of contract rights or the taking of property without fair consideration. Most of our international sales are to large international or national oil companies and these sales have resulted in a concentration of receivables from certain national oil companies in Latin America. As of December 31, 2016 , Latin America accounted for 38% of our net outstanding accounts receivables. Venezuela, Ecuador and Mexico represent 43% , 16% and 10% , respectively, of the Latin America balance. In 2016, we accepted a note with a face value of $120 million from Petroleos de Venezuela, S.A. (“PDVSA”) in exchange for $120 million in net trade receivables. The note had a three year term at a 6.5% stated interest rate. We carried the note at fair value and recognized a loss in the second quarter of 2016 of $84 million to adjust the note to fair value. In the fourth quarter of 2016, we sold the economic rights in the note receivable for $44 million and recognized a gain of $8 million . During 2016 , 2015 and 2014 , no individual customer accounted for more than 10% of our consolidated revenues.
Inventories	Inventories We value our inventories at lower of cost or market using either the first-in, first-out (“FIFO”) or average cost method. Cost represents third-party invoice or production cost. Production cost includes material, labor and manufacturing overhead. Work in process and finished goods inventories include the cost of materials, labor and manufacturing overhead. To maintain a book value that is the lower of cost or market, we maintain reserves for excess, slow moving and obsolete inventory. We regularly review inventory quantities on hand and record provisions for excess, slow moving and obsolete inventory.
Property, Plant and Equipment	Property, Plant and Equipment We carry our property, plant and equipment, both owned and under capital lease, at cost less accumulated depreciation. The carrying values are based on our estimates and judgments relative to capitalized costs, useful lives and salvage value, where applicable. We expense maintenance and repairs as incurred. We capitalize expenditures for improvements as well as renewals and replacements that extend the useful life of the asset. We depreciate our fixed assets on a straight-line basis over their estimated useful lives, allowing for salvage value where applicable. Our depreciation expense was $896 million , $1.1 billion and $1.3 billion for the years ended December 31, 2016 , 2015 and 2014 , respectively. We classify our rig assets as “ Rental and Service Equipment ” on the Consolidated Balance Sheets . The estimated useful lives of our major classes of PP&E are as follows: Major Classes of Property, Plant and Equipment Estimated Useful Lives Buildings and leasehold improvements 10 – 40 years or lease term Rental and service equipment 2 – 20 years Machinery and other 2 – 12 years
Goodwill and Indefinite Lived Intangibles Assets	Goodwill Goodwill represents the excess of consideration paid over the fair value of net tangible and identifiable intangible assets acquired in a business combination. Goodwill is not amortized but is evaluated for impairment. We perform an impairment test for goodwill annually as of October 1 or more frequently if indicators of potential impairment exist that would more-likely-than-not reduce the fair value of the reporting unit below its carrying value. Goodwill impairment is evaluated using a two-step process. The first step of the goodwill impairment test involves a comparison of the fair value of each of our reporting units with their carrying values. We have the option to assess qualitative factors to determine if it is necessary to perform the first step of the impairment test. If it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying value, further testing is not required. If the fair value of a reporting unit is less than the recorded book value of the reporting unit’s net assets (including goodwill), then a hypothetical purchase price allocation is performed on the reporting unit’s assets and liabilities using the fair value of the reporting unit as the purchase price in the calculation. If the implied fair value of goodwill is less than the recorded amount of goodwill, the recorded goodwill is written down to the new amount.
Intangible Assets	Intangible Assets Our intangible assets, excluding goodwill, are acquired technology, licenses, patents, customer relationships and other identifiable intangible assets. Intangible assets are amortized on a straight-line basis over their estimated economic lives generally ranging from two to 20 years, except for intangible assets with indefinite lives, which are not amortized. As many areas of our business rely on patents and proprietary technology, we seek patent protection both inside and outside the U.S. for products and methods that appear to have commercial significance. We capitalize patent defense costs when we determine that a successful defense is probable.
Long-Lived Assets	Long-Lived Assets We initially record our long-lived assets at cost, and review on a regular basis to determine whether any events or changes in circumstances indicate the carrying amount of the assets may not be recoverable. Factors that might indicate a potential impairment may include, but are not limited to, significant decreases in the market value of the long-lived asset, a significant change in the long-lived asset’s physical condition, the introduction of competing technologies, legal challenges, a reduction in the utilization rate of the assets, a change in industry conditions or a reduction in cash flows associated with the use of the long-lived asset. If these or other factors indicate the carrying amount of the asset may not be recoverable, we determine whether an impairment has occurred through analysis of undiscounted cash flow of the asset at the lowest level that has an identifiable cash flow. If an impairment has occurred, we recognize a loss for the difference between the carrying amount and the fair value of the asset. We estimate the fair value of the asset using market prices when available or, in the absence of market prices, based on an estimate of discounted cash flows or replacement cost. Cash flows are generally discounted using an interest rate commensurate with a weighted average cost of capital for a similar asset.
Research and Development Expenditures	Research and Development Expenditures Research and development expenditures are expensed as incurred.
Environmental Expenditures	Environmental Expenditures Environmental expenditures that relate to the remediation of an existing condition caused by past operations and that do not contribute to future revenues are expensed. Liabilities for these expenditures are recorded when it is probable that obligations have been incurred and costs can be reasonably estimated. Estimates are based on available facts and technology, enacted laws and regulations and our prior experience in remediation of contaminated sites.
Derivatives Financial Instruments	Derivative Financial Instruments We record derivative instruments on the balance sheet at their fair value as either assets or liabilities. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income (loss), depending on whether the derivative is designated as part of a hedge relationship, and if so, the type of hedge.
Foreign Currency	Foreign Currency Results of operations for our foreign subsidiaries with functional currencies other than the U.S. dollar are translated using average exchange rates during the period. Assets and liabilities of these foreign subsidiaries are translated using the exchange rates in effect at the balance sheet dates, and the resulting translation adjustments are included in Accumulated Other Comprehensive Loss, a component of shareholders’ equity. For our subsidiaries that have a functional currency that differs from the currency of their balances and transactions, inventories, PP&E and other non-monetary assets and liabilities, together with their related elements of expense or income, are remeasured into the functional currency using historical exchange rates. All monetary assets and liabilities are remeasured into the functional currency at current exchange rates. All revenues and expenses are translated into the functional currency at average exchange rates. Remeasurement gains and losses for these subsidiaries are recognized in our results of operations during the period incurred. We had net foreign currency losses, net of gains and losses on foreign currency derivatives (See “ Note 15 – Derivative Instruments ”), but excluding charges relating to the Venezuelan bolivar fuertes (“bolivar”), the Angolan kwanza, Argentinian peso, Egyptian pound and Kazakhstani tenge as described under the caption “Currency Devaluation and Related Charges,” of $9 million , $53 million and $18 million in 2016 , 2015 and 2014 , respectively, which are included in “ Other Income (Expense), Net ” on the accompanying Consolidated Statements of Operations . Currency Devaluation and Related Charges Currency devaluation charges are included in current earnings in “ Currency Devaluation Charges ” on the accompanying Consolidated Statements of Operations. In 2016, currency devaluation charges include charges related to the Angolan kwanza of $31 million and the Egyptian pound of $10 million . In 2015, currency devaluations charges of $85 million include charges related to the Angolan kwanza of $39 million , the Venezuelan bolivar of $26 million , the Argentina peso of $11 million and Kazakhstani tenge of $9 million . In 2014, currency charges include $245 million related to the Venezuelan bolivar. The charges were related to our adoption of the SICAD II exchange rate provided by Venezuela’s Supplementary Foreign Currency Administration System approximately of 50 Venezuelan bolivars per U.S. dollar.
Share-Based Compensation	Share-Based Compensation We account for all share-based payment awards, including shares issued under employee stock purchase plans, stock options, restricted shares, restricted share units and performance units by measuring these awards at the date of grant and recognizing the grant date fair value as an expense, net of expected forfeitures, over the service period, which is usually the vesting period.
Income Taxes	Income Taxes Income taxes have been provided based upon the tax laws and rates in the countries in which our operations are conducted and income is earned. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance for deferred tax assets is recorded when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized. The impact of an uncertain tax position taken or expected to be taken on an income tax return is recognized in the financial statements at the largest amount that is more likely than not to be sustained upon examination by the relevant taxing authority.
Revenue Recognition	Revenue Recognition Revenue is recognized when all of the following criteria have been met: (1) evidence of an arrangement exists; (2) delivery to and acceptance by the customer has occurred; (3) the price to the customer is fixed or determinable; and (4) collectability is reasonably assured. Our services and products are generally sold based upon purchase orders, contracts or other persuasive evidence of an arrangement with our customers that include fixed or determinable prices but do not generally include right of return provisions or other significant post-delivery obligations. Our products are produced in a standard manufacturing operation, even if produced to our customer’s specifications. Revenue is recognized for products upon delivery and when the customers assume the risks and rewards of ownership. Revenue is recognized for services when they are rendered. Both contract drilling and pipeline service revenue is contractual by nature and generally governed by day-rate based contracts. We recognize revenue for day-rate contracts as the services are rendered. Up-front payments for preparation and mobilization of equipment and personnel in connection with new drilling contracts are deferred along with any related incremental costs incurred directly related to preparation and mobilization. The deferred revenue and costs are recognized over the primary contract term using the straight-line method. Costs of relocating equipment without contracts are expensed as incurred. Demobilization fees received are recognized, along with any related expenses, upon completion of contracts. We incur rebillable expenses including shipping and handling, third-party inspection and repairs, and customs costs and duties. We recognize the revenue associated with these rebillable expenses when reimbursed by customers as Product Revenues and all related costs as Cost of Products in the accompanying Consolidated Statements of Operations .
Percentage- of- Completion	Percentage-of-Completion Revenue from certain long-term construction type contracts is reported based on the percentage-of-completion method of accounting. This method of accounting requires us to calculate contract profit to be recognized in each reporting period for each contract based upon our projections of future outcomes, which include: • estimates of the available revenue under the contracts; • estimates of the total cost to complete the project; • estimates of project schedule and completion date; • estimates of the extent of progress toward completion; and • change order amounts or claims included in revenue. Measurements of progress are based on costs incurred to date as a percentage of total estimated costs or output related to physical progress. At the outset of each contract, we prepare a detailed analysis of our estimated cost to complete the project. Risks related to service delivery, usage, productivity and other factors are considered in the estimation process. We periodically evaluate the estimated costs, claims, change orders and percentage-of-completion at the contract level. The recording of profits and losses on long-term contracts requires an estimate of the total profit or loss over the life of each contract. This estimate requires consideration of total contract value, change orders and claims, less costs incurred and estimated costs to complete. Anticipated losses on contracts are recorded in full in the period in which they become evident. Profits are recorded based upon the total estimated contract profit multiplied by the current estimated percentage complete for the contract. There are many factors that impact future costs, including but not limited to weather, inflation, customer activity levels and budgeting constraints, labor and community disruptions, timely availability of materials, productivity and other factors.
Earnings per Share	Earnings per Share Basic earnings per share for all periods presented equals net income divided by the weighted average number of our shares outstanding during the period including participating securities. Diluted earnings per share is computed by dividing net income by the weighted average number of our shares outstanding during the period including participating securities, adjusted for the dilutive effect of our stock options, restricted shares and performance units. Unvested share-based payment awards and other instruments issued by the Company that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are participating securities and are included in the computation of earnings per share following the two-class method. Accordingly, we include our restricted share awards (“RSA”) and the outstanding warrant, which contain the right to receive dividends, in the computation of both basic and diluted earnings per share when diluted.
New Accounting Pronouncements	New Accounting Pronouncements Accounting Changes In April 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs , which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. We adopted ASU 2015-03 in the first quarter of 2016 retrospectively, which reduced Long-term debt and Other non-current assets by $27 million as of December 31, 2015. In November 2015, the FASB issued ASU 2015-17 , Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which eliminates the current requirement to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. We adopted ASU 2015-17 in the fourth quarter of 2016 and have reclassified net current deferred tax assets of $257 million and net current deferred tax liabilities of $33 million into non-current deferred tax asset and liabilities. We adopted ASC 2015-17 prospectively and no prior periods have been restated to conform to the new presentation. The adoption has no effect on net income or cash flows. Accounting Standards Issued Not Yet Adopted In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory , which eliminates a current exception in U.S. GAAP to the recognition of the income tax effects of temporary differences that result from intra-entity transfers of non-inventory assets. The intra-entity exception is being eliminated under the ASU. The standard is required to be applied on a modified retrospective basis and will be effective beginning with the first quarter of 2018. Early adoption is permitted, and we are evaluating the impact that this new standard will have on our Consolidated Financial Statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . ASU 2016-15 provides guidance on the cash flow reporting of certain issues that were either unclear or not addressed under existing U.S. GAAP. The standard requires the retrospective transition method to each period presented and will be effective beginning with the first quarter of 2018, although early adoption is permitted. We are evaluating the impact that ASC 2016-15 will have on our Consolidated Statements of Cash Flows. In June 2016, the FASB issued ASU 2016-13 , Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. The new standard applies to trade receivables and requires expected credit losses to be based on past events, current conditions and reasonable and supportable forecasts that affect the instrument’s collectability. The new standard will be effective for us beginning with the first quarter of 2020. Early adoption is permitted in 2019. We are evaluating the impact that this new standard will have on our Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which impacts certain aspects of the accounting for share-based payment transactions. This update provides various transition requirements that include both prospective, modified retrospective and retrospective application guidance. The new standard will be effective for us beginning with the first quarter of 2017. Early adoption is permitted, but it must include all amendments in the same period. We are evaluating the impact that this new standard will have on our Consolidated Financial Statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires a lessee to recognize a lease asset and lease liability for most leases, including those classified as operating leases under existing GAAP. The ASU also changes the definition of a lease and requires expanded quantitative and qualitative disclosures for both lessees and lessors. Under ASU 2016-02, we will revise our leasing policies to require most of the leases, where we are the lessee, to be recognized on the balance sheet as a lease asset and lease liability whereas currently we do not recognize operating leases on our balance sheet. Further, we will separate leases from other contracts where we are either the lessor or lessee when the rights conveyed under the contract indicate there is a lease, where we may not be required to do so under existing policies. While we cannot calculate the impact ASU 2016-02 will have on Weatherford’s financial statements, we anticipate that Weatherford’s assets and liabilities will increase by a significant amount. This standard will be effective for us beginning with the first quarter of 2019. We do not anticipate adopting ASU 2016-02 early, which is permitted under the standard. ASU 2016-02 requires lessees and lessors to recognize and measure leases at the beginning of the earlies period presented using a modified retrospective transition method but permits certain practical expedients to be applied, which may exclude certain leases that commenced before the effective date. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory , which requires inventory not measured using either the last in, first out (LIFO) or the retail inventory method to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable cost of completion, disposal, and transportation. The new standard will be effective for us beginning with the first quarter of 2017, and will be applied prospectively. Early adoption is permitted. We do not expect the impact of our adoption to have a material effect on our Consolidated Financial Statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , which will replace most existing revenue recognition guidance in GAAP. ASU 2014-09 will require an entity to recognize revenue 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. ASU 2014-09 requires a five-step approach to recognizing revenue: 1) identify the contract, 2) identify performance obligations, 3) determine the transaction price, 4) allocate the transaction price, and 5) recognize revenue. Subsequent to ASU 2014-09’s issuance, Topic 606 has been affected by other FASB updates that address certain aspects or Topic 606 or revised the effective date of the accounting changes. Under ASU 2014-09, we will revise our revenue recognition policy to require revenue recognition when control passes. This is a change from current policies, which generally require revenue recognition when delivery has occurred and risk and rewards of ownership have passed. Further, we will also begin estimating variable revenues and recognizing them sooner, whereas under current policies such variable revenues were generally not recognized until their collection was determinable. The impact of these and other changes will be to either slow the recognition of revenue in certain situations and to accelerate it in others. The expected impact is not yet determinable. The changes are not expected to have any direct impact to our cash flows. We intend to adopt ASU 2014-09 as of its effective date in the first quarter 2018. ASU 2014-09 permits two transition methods: the retrospective or the modified retrospective. The retrospective method is applied by restating all prior years whereas the modified retrospective method requires the recognition of a cumulative effect as an adjustment to opening retained earnings. Weatherford is currently evaluating the transition method it will select, but will likely utilize the modified retrospective method. We have planned and commenced our implementation of ASU 2014-09. We are in the process of assessing differences from current accounting practices (gap analysis). Remaining implementation matters include completing the gap analysis, implementing appropriate technology enhancements, establishing new policies, procedures, and controls, and quantifying any adoption date adjustments.
