Accounting Policies [Abstract]
Summary of significant accounting policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations Baker Hughes Incorporated (“Baker Hughes,” “Company,” “we,” “our,” or “us,”) is a leading supplier of oilfield services, products, technology and systems used in the worldwide oil and natural gas industry. We also provide products and services for other businesses including downstream chemicals, and process and pipeline services. Basis of Presentation Our consolidated financial statements are prepared in conformity with United States generally accepted accounting principles ("GAAP"). The consolidated financial statements include the accounts of Baker Hughes and all of our subsidiaries where we exercise control. For investments in subsidiaries that are not wholly-owned, but where we exercise control, the equity held by the minority owners and their portions of net income (loss) are reflected as noncontrolling interests. Investments over which we have the ability to exercise significant influence over operating and financial policies, but do not hold a controlling interest, are accounted for using the equity method of accounting. Intercompany accounts and transactions have been eliminated in consolidation. In the Notes to Consolidated Financial Statements, all dollar and share amounts in tabulations are in millions of dollars and shares, respectively, unless otherwise indicated. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, disclosure of any contingent assets or liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We base our estimates and judgments on historical experience and on various other assumptions and information that are believed to be reasonable under the circumstances. Estimates and assumptions about future events and their effects cannot be perceived with certainty, and accordingly, these estimates may change as new events occur, as more experience is acquired, as additional information is obtained and as our operating environment changes. While we believe that the estimates and assumptions used in the preparation of the consolidated financial statements are appropriate, actual results could differ from those estimates. Estimates are used for, but are not limited to, determining the following: allowance for doubtful accounts and inventory valuation reserves; recoverability of long-lived assets; useful lives used in depreciation and amortization; income taxes and related valuation allowances; accruals for contingencies; actuarial assumptions to determine costs and liabilities related to employee benefit plans; stock-based compensation expense and the fair value of assets acquired and liabilities assumed in acquisitions. Revenue Recognition Our products and services are sold based upon purchase orders, contracts or other agreements with the customer that include fixed or determinable prices and that do not include right of return or other similar provisions or other significant post-delivery obligations. We recognize revenue for products sold upon delivery, when title passes, when collectability is reasonably assured and when there are no further significant obligations for future performance. Provisions for estimated warranty returns or similar arrangements are made at the time the related revenue is recognized. Revenue for services is recognized as the services are rendered and when collectability is reasonably assured. Rates for services are typically priced on a per day, per distance drilled, per man hour or similar basis. In certain situations, revenue is generated from transactions that may include multiple products and services under one contract or agreement and which may be delivered to the customer over an extended period of time. Revenue from these arrangements is recognized in accordance with the above criteria and as each item or service is delivered based on their relative fair value. Research and Engineering Research and engineering expenses are expensed as incurred and include costs associated with the research and development of new products and services and costs associated with sustaining engineering of existing products and services. Costs for research and development of new products and services were $347 million , $430 million and $370 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Cash and Cash Equivalents Cash equivalents include only those investments with an original maturity of three months or less. We maintain cash deposits with financial institutions that may exceed federally insured limits. We monitor the credit ratings and our concentration of risk with these financial institutions on a continuing basis to safeguard our cash deposits. Allowance for Doubtful Accounts We establish an allowance for doubtful accounts based on various factors including the payment history and financial condition of our customers and the economic environment. Provisions for doubtful accounts are recorded based on the aging status of the customer accounts or when it becomes evident that the customer will not make the required payments at either contractual due dates or in the future. Provision for doubtful accounts recorded in cost of sales was $193 million , $102 million and $75 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Concentration of Credit Risk We grant credit to our customers who primarily operate in the oil and natural gas industry. Although this concentration affects our overall exposure to credit risk, our trade receivables are spread over a diverse group of customers across many countries, which mitigates this risk. We perform periodic credit evaluations of our customers’ financial condition, including monitoring our customers’ payment history and current credit worthiness to manage this risk. We do not generally require collateral in support of our trade receivables, but we may require payment in advance or security in the form of a letter of credit or bank guarantee. During 2015, 2014 and 2013, no individual customer accounted for more than 10% of our consolidated revenue. Inventories Inventories are stated at the lower of cost or market. Cost is determined using the average cost method, and includes the cost of materials, labor and manufacturing overhead. As necessary, we record provisions and maintain reserves for excess, slow moving and obsolete inventory. To determine these reserve amounts, we regularly review inventory quantities on hand and compare them to estimates of future product demand, market conditions, production requirements and technological developments. Property, Plant and Equipment and Accumulated Depreciation Property, plant and equipment (“PP&E”) is stated at cost less accumulated depreciation, which is generally provided by using the straight-line method over the estimated useful lives of the individual assets. Significant improvements and betterments are capitalized if they extend the useful life of the asset. We manufacture a substantial portion of our tools and equipment and the cost of these items, which includes direct and indirect manufacturing costs, is capitalized and carried in inventory until it is completed. When complete, the cost is reflected in capital expenditures and is classified as machinery, equipment and other in PP&E. Maintenance and repairs are charged to expense as incurred. Upon sale or other disposition, the applicable amounts of asset cost and accumulated depreciation are removed from the balance sheet and the net amount, less proceeds from disposal, is charged or credited to income. The capitalized costs of computer software developed or purchased for internal use are classified in machinery, equipment and other. Goodwill, Intangible Assets and Amortization Goodwill is the excess of the consideration transferred over the fair value of the tangible and identifiable intangible assets and liabilities recognized in acquisitions. Goodwill and intangible assets with indefinite lives are not amortized. Intangible assets with finite useful lives are amortized on a basis that reflects the pattern in which the economic benefits of the intangible assets are realized, which is generally on a straight-line basis over the asset’s estimated useful life. Impairment of PP&E, Intangibles, Other Long-lived Assets and Goodwill We review PP&E, intangible assets and certain other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable and at least annually for certain intangible assets. The determination of recoverability is made based upon the estimated undiscounted future net cash flows. The amount of impairment loss, if any, is determined by comparing the fair value, as determined by a discounted cash flow analysis, with the carrying value of the related assets. We perform an annual impairment test of goodwill for each of our reporting units as of October 1, or more frequently if an event occurs or circumstances change to indicate that it is more likely than not that an impairment may exist. Our reporting units are based on our organizational and reporting structure and are the same as our five reportable segments. Corporate and other assets and liabilities are allocated to the reporting units to the extent that they relate to the operations of those reporting units in determining their carrying amount. When performing the annual impairment test we have the option of first performing a qualitative assessment to determine the existence of events and circumstances that would lead to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If such a conclusion is reached, we would then be required to perform a quantitative impairment assessment of goodwill. However, if the assessment leads to a determination that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then no further assessments are required. In 2015 and 2014, we performed a qualitative assessment for our annual goodwill impairment test. In 2013, a quantitative assessment for the determination of impairment was made by comparing the carrying amount of each reporting unit with its fair value, which is generally calculated using a combination of market, comparable transaction and discounted cash flow approaches. In performing our annual goodwill impairment analysis for 2015, our qualitative assessment included consideration of current industry and market conditions and circumstances as well as any mitigating factors that would most affect the fair value of the Company and its reporting units. Among those mitigating factors, we considered the value of the consideration to be received at closing of the Merger (as defined below), based on the terms of the Merger Agreement (as defined below), compared to the carrying value of the Company and its reporting units. Based on our assessment and consideration of the totality of the facts and circumstances, including our business environment in the fourth quarter of 2015, we determined that it is not more likely than not that the fair value of the Company or any of its reporting units is less than their respective carrying amounts; however, a decline in our stock price could require an impairment in future periods. As such, no impairments of goodwill were recorded for the year ended December 31, 2015, or any of the prior years included in the accompanying financial statements. Income Taxes We use the liability method in determining our provision and liabilities for our income taxes, under which current and deferred tax liabilities and assets are recorded in accordance with enacted tax laws and rates. Deferred tax liabilities and assets, which are computed on the estimated income tax effect of temporary differences between financial and tax bases in assets and liabilities, are determined using the tax rate expected to be in effect when taxes are actually paid or recovered. A valuation allowance to reduce deferred tax assets is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized. We intend to indefinitely reinvest certain earnings of our foreign subsidiaries in operations outside the U.S., and accordingly, we have not provided for U.S. income taxes on such earnings. We do provide for the U.S. and additional non-U.S. taxes on earnings anticipated to be repatriated from our non-U.S. subsidiaries. Our tax filings for various periods are subject to audit by tax authorities in most jurisdictions where we conduct business. These audits may result in assessments of additional taxes that are resolved with the authorities or through the courts. We have provided for the amounts we believe will ultimately result from these proceedings. In addition to the assessments that have been received from various tax authorities, we also provide for taxes for uncertain tax positions where formal assessments have not been received. We classify interest and penalties related to uncertain tax positions as income taxes in our financial statements. Environmental Matters Estimated remediation costs are accrued using currently available facts, existing environmental permits, technology and enacted laws and regulations. Our cost estimates are developed based on internal evaluations and are not discounted. Accruals are recorded when it is probable that we will be obligated to pay for environmental site evaluation, remediation or related activities, and such costs can be reasonably estimated. As additional information becomes available, accruals are adjusted to reflect current cost estimates. Ongoing environmental compliance costs, such as obtaining environmental permits, installation of pollution control equipment and waste disposal are expensed as incurred. Where we have been identified as a potentially responsible party in a U.S. federal or state Comprehensive Environmental Response, Compensation and Liability Act (“Superfund”) site, we accrue our share of the estimated remediation costs of the site. This share is based on the ratio of the estimated volume of waste we contributed to the site to the total volume of waste disposed at the site. Foreign Currency A number of our significant foreign subsidiaries have designated the local currency as their functional currency and, as such, gains and losses resulting from balance sheet translation of foreign operations are included as a separate component of accumulated other comprehensive loss within stockholders’ equity. Gains and losses from foreign currency transactions, such as those resulting from the settlement of receivables or payables in the non-functional currency, are included in marketing, general and administrative (“MG&A”) expenses in the consolidated statements of income (loss) as incurred. For those foreign subsidiaries that have designated the U.S. Dollar ("USD") as the functional currency, monetary assets and liabilities are remeasured at period-end exchange rates, and nonmonetary items are remeasured at historical exchange rates. Gains and losses resulting from this balance sheet remeasurement are also included in MG&A expenses as incurred. In 2015 and 2014, the Venezuelan government modified its currency exchange systems, which impacted the rate at which we could reasonably expect to exchange the Venezuelan Bolivars Fuertes ("BsF") for the U.S. Dollar. As a result of the change in the exchange rate, in 2015 and 2014, we recognized a foreign currency loss of approximately $5 million and $12 million , respectively, related to the remeasurement of our BsF denominated assets and liabilities. This loss was recorded in MG&A expenses. We believe any further devaluation of Venezuela's currency would not have a material impact on our financial position, results of operations or cash flows. In 2013, Venezuela's currency was devalued from the prior exchange rate of 4.3 BsF per USD to 6.3 BsF per USD. The impact of this devaluation was a loss of $23 million that was recorded in MG&A expenses. Fair Value Measurement The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at a measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: • Level One: The use of quoted prices in active markets for identical financial instruments. • Level Two: The use of quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active or other inputs that are observable in the market or can be corroborated by observable market data. • Level Three: The use of significantly unobservable inputs that typically require the use of management's estimates of assumptions that market participants would use in pricing. Financial Instruments Our financial instruments include cash and cash equivalents, accounts receivable, investments, accounts payable, short and long-term debt, and derivative financial instruments. Except for long-term debt, the estimated fair value of our financial instruments at December 31, 2015 and 2014 approximates their carrying value as reflected in our consolidated balance sheets. For further information on the fair value of our debt, see Note 12. "Indebtedness." We monitor our exposure to various business risks including commodity prices, foreign currency exchange rates and interest rates and regularly use derivative financial instruments to manage these risks. Our policies do not permit the use of derivative financial instruments for speculative purposes. At the inception of a new derivative, we designate the derivative as a hedge or we determine the derivative to be undesignated as a hedging instrument. We document the relationships between the hedging instruments and the hedged items, as well as our risk management objectives and strategy for undertaking various hedge transactions. We assess whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of the hedged item at both the inception of the hedge and on an ongoing basis. We have a program that utilizes foreign currency forward contracts to reduce the risks associated with the effects of certain foreign currency exposures. Under this program, our strategy is to have gains or losses on the foreign currency forward contracts mitigate the foreign currency transaction and translation gains or losses to the extent practical. These foreign currency exposures typically arise from changes in the value of assets and liabilities which are denominated in currencies other than the functional currency. Our foreign currency forward contracts generally settle in less than 180 days. We record all derivatives as of the end of our reporting period in our consolidated balance sheet at fair value. For those forward contracts designated as fair value hedging instruments or held as undesignated hedging instruments, we record the changes in fair value of the forward contracts in our consolidated statements of income (loss) along with the change in fair value of the hedged item. Changes in the fair value of forward contracts designated as cash flow hedging instruments are recognized in other comprehensive income until the hedged item is recognized in earnings. For derivatives designated as a cash flow hedge, the ineffective portion of that derivative's change in fair value is recognized in earnings. Recognized gains and losses on derivatives entered into to manage foreign currency exchange risk are included in MG&A expenses in the consolidated statements of income (loss). We had outstanding foreign currency forward contracts with notional amounts aggregating $499 million and $580 million to hedge exposure to currency fluctuations in various foreign currencies at December 31, 2015 and 2014 , respectively. Based on quoted market prices as of December 31, 2015 or 2014 for forward contracts with similar terms and maturity dates, we recorded losses of $1 million and $11 million , respectively, to adjust these forward contracts to their fair market value. New Accounting Standards Updates In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers . The ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. The new standard also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity's nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The pronouncement is to be applied retrospectively and is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted as of January 1, 2017. We have not completed an evaluation of the impact the pronouncement will have on our consolidated financial statements and related disclosures. In April 2015, the FASB issued ASU No. 2015-3, Simplifying the Presentation of Debt Issuance Costs . The ASU 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, consistent with debt discounts. The pronouncement is effective for annual reporting periods beginning after December 15, 2015. We currently report debt issuance costs consistent with the guidance of this ASU; therefore there will be no impact on our consolidated financial statements and related disclosures upon adoption. In April 2015, the FASB issued ASU No. 2015-5, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement . The ASU provides guidance to customers about whether a cloud computing arrangement includes a software license and the related accounting treatment. The pronouncement is effective for annual reporting periods beginning after December 15, 2015. Adoption of this pronouncement is not expected to have a material impact on our consolidated financial statements or related disclosures. In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory , which requires inventory measured using the FIFO or average cost methods to be subsequently measured at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Currently, inventory measured using these methods is required to be subsequently measured at the lower of cost or market with market defined as replacement cost, net realizable value or net realizable value less a normal profit margin. This pronouncement is effective for annual reporting periods beginning after December 15, 2016 on a prospective basis. Early adoption is permitted. We have not completed an evaluation of the impact the pronouncement will have on our consolidated financial statements and related disclosures. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes , which amends existing guidance on income taxes to require the classification of all deferred tax assets and liabilities as noncurrent on the balance sheet. The pronouncement is effective for annual reporting periods beginning after December 15, 2016, and may be applied either prospectively or retrospectively. We have not completed an evaluation of the impact the pronouncement will have on our consolidated financial statements and related disclosures.

Business Combinations [Abstract]
Mergers, acquisitions and dispositions disclosures	HALLIBURTON MERGER AGREEMENT On November 16, 2014, Baker Hughes, Halliburton Company (“Halliburton”) and a wholly owned subsidiary of Halliburton (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), under which Halliburton will acquire all of the outstanding shares of Baker Hughes through a merger of Baker Hughes with and into Merger Sub (the "Merger"). Subject to certain specified exceptions, at the effective time of the Merger, each share of Baker Hughes common stock will be converted into the right to receive (i) 1.12 shares of Halliburton common stock and (ii) $19.00 in cash. On March 27, 2015, Halliburton's stockholders approved the proposal to issue shares of Halliburton common stock as contemplated by the Merger Agreement. In addition, Baker Hughes’ stockholders adopted the Merger Agreement and thereby approved the proposed combination of the two companies. The obligation of the parties to consummate the Merger is still subject to additional customary closing conditions, including: (i) applicable regulatory approvals; (ii) the absence of legal restraints and prohibitions; and (iii) other customary closing conditions. Halliburton is required to take all actions necessary to obtain regulatory approvals (including agreeing to divestitures) unless the assets, businesses or product lines subject to such actions would account for more than $7.5 billion of 2013 revenue. Under the U.S. Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act") and the rules promulgated thereunder by the Federal Trade Commission (the “FTC”), the Merger cannot be completed until each of Halliburton and Baker Hughes has filed a notification and report form with the FTC and the Antitrust Division of the Department of Justice (the “DOJ”) under the HSR Act and the applicable waiting period has expired or been terminated. Each of Halliburton and Baker Hughes filed an initial notification and report form on December 8, 2014. Halliburton withdrew its filing on January 7, 2015 and refiled on January 9, 2015 in order to provide the FTC and the DOJ with an additional 30-day period to review the filings. On February 9, 2015, the DOJ issued a request for additional information under the HSR Act (the “Second Request”). On July 10, 2015, Halliburton and Baker Hughes entered into a timing agreement with the DOJ, and on September 28, 2015, Halliburton and Baker Hughes announced an amendment to the timing agreement which extended the period for the DOJ's review of the Merger to the later of December 15, 2015 or 30 days following the date on which both companies have certified final, substantial compliance with the Second Request. On December 16, 2015, Baker Hughes' and Halliburton's timing agreement with the DOJ expired without reaching a settlement or the DOJ initiating litigation to block the pending Merger. The companies intend to continue their discussions with the DOJ and other competition agencies that have expressed an interest in the transaction, and remain focused on completing the Merger as early as possible in 2016. In that regard, Baker Hughes and Halliburton have agreed to extend the period for the parties to obtain required competition approvals to April 30, 2016, as permitted under the Merger Agreement, though the parties would proceed with closing prior to such date if all relevant competition approvals have been obtained. If review by the relevant competition authorities extends beyond April 30, 2016, the Merger Agreement does not terminate automatically; the parties may continue to seek relevant competition approvals or either of the parties may terminate the Merger Agreement. Baker Hughes cannot predict with certainty when, or if, the Merger will be completed because completion of the Merger is subject to conditions beyond the control of Baker Hughes. Baker Hughes and Halliburton each made customary representations, warranties and covenants in the Merger Agreement, including, among others, covenants by each of Baker Hughes and Halliburton to, subject to certain exceptions, conduct its business in the ordinary course. In particular, among other restrictions and subject to certain exceptions, Baker Hughes agreed to generally refrain from acquiring new businesses, incurring new indebtedness, repurchasing shares, issuing new common stock or equity awards (other than equity awards granted to employees, officers and directors materially consistent with historical long-term incentive awards granted), or entering into new material contracts or commitments outside the normal course of business, without the consent of Halliburton, during the period between the execution of the Merger Agreement and the consummation of the Merger. With respect to equity awards granted after the Merger Agreement to officers and employees, such awards will not vest solely as a result of the Merger but will be converted to an equivalent Halliburton equity award. However, they will vest entirely if an officer or employee is terminated within one year following the closing of the Merger with Halliburton. Baker Hughes and Halliburton are each permitted to pay regular quarterly cash dividends during such period. In addition, under the terms of the Merger Agreement, Halliburton and Baker Hughes have agreed to coordinate the declaration and payment of dividends in respect of each party's common stock including record dates and payment dates relating thereto, which we expect to be in the third month of each quarter. Under the Merger Agreement, we have agreed not to increase the quarterly dividend while the Merger is pending. In the event the Merger Agreement is terminated by (i) either party as a result of the failure of the Merger to occur on or before the end date (as it may be extended) due to the failure to achieve certain specified antitrust-related approvals when all other closing conditions (other than receipt of antitrust and other specified regulatory approvals and conditions that by their nature cannot be satisfied until the closing but subject to such conditions being capable of being satisfied if the closing date were the date of termination) have been satisfied, (ii) either party as a result of any antitrust-related final, non-appealable order or injunction prohibiting the closing, or (iii) Baker Hughes as a result of Halliburton’s material breach of its obligations to obtain regulatory approval such that the antitrust-related condition to closing is incapable of being satisfied, then in each case Halliburton would be required to pay Baker Hughes a termination fee of $3.5 billion . Baker Hughes incurred costs related to the Merger of $295 million during 2015, including costs under our retention program and obligations for minimum incentive compensation costs, which, based on meeting eligibility criteria, have been treated as Merger related expenses. ACQUISITIONS In September 2014, we completed the acquisition of the pipeline and specialty services business of Weatherford International Ltd. ("PSS") for total cash consideration of $248 million , subject to the finalization of the post-closing working capital adjustments. PSS provides an expanded range of pre-commissioning, deepwater and in-line inspection services worldwide and is included in our Industrial Services segment. The transaction has been accounted for using the acquisition method of accounting and accordingly, assets acquired and liabilities assumed were recorded at their fair values as of the acquisition date. As a result of the acquisition, we recorded approximately $73 million of goodwill and approximately $37 million of intangible assets. Pro forma results of operations for this acquisition have not been presented because the effect of this acquisition was not material to our consolidated financial statements.

Impairment and Restructuring Co

Impairment and Restructuring Costs - (Notes)	12 Months Ended

Restructuring and Related Activities [Abstract]
Restructuring and Other Charges	IMPAIRMENT AND RESTRUCTURING CHARGES IMPAIRMENT CHARGES We conduct impairment tests on long-lived assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable based on estimated future cash flows. In the fourth quarter of 2015, negative market sentiment increased and oil prices fell to a seven year low. Additionally, the current market outlook is for a prolonged recovery. We considered these events to be possible impairment indicators and performed testing of long-lived assets for impairment. As a result of our testing, certain machinery and equipment, with a total carrying value of $1.64 billion , was written down to its estimated fair value, resulting in an impairment charge of $1.05 billion . Additionally, certain intangible assets, comprised of customer relationships and trade names, with a total carrying value of $178 million , were written down to their estimated fair values, resulting in an impairment charge of $116 million . Total impairment charges for 2015 were $1.16 billion . The majority of the machinery and equipment and intangible assets impaired related to our pressure pumping business in North America. The estimated fair values for these assets were determined using discounted future cash flows. The significant level 3 unobservable inputs used in the determination of the fair value of these assets were the estimated future cash flows and the weighted average cost of capital of 9.8% . RESTRUCTURING CHARGES Beginning in the second half of 2014 and throughout 2015, the oil and natural gas market experienced a significant over supply of capacity leading to a substantial and rapid decline in oil prices resulting in significantly lower activity and customer spending. Accordingly, to adjust to the lower level of activity, beginning in the first quarter of 2015, we initiated actions to restructure and adjust our operations and cost structure to reflect current and expected near-term activity levels. These restructuring activities included workforce reductions, contract terminations, facility closures and the removal of excess machinery and equipment that resulted in asset impairments. As a result of these restructuring activities, we recorded restructuring charges of $830 million in 2015. Depending on future market conditions and activity levels, further actions may be necessary to adjust our operations which may result in additional charges. Our restructuring charges as summarized below: Restructuring Charges Year Ended December 31, 2015 Workforce reductions $ 436 Contract terminations 121 Impairment of buildings and improvements 82 Impairment of machinery and equipment 191 Total restructuring charges $ 830 Workforce reduction costs : During 2015 , we initiated workforce reductions that will result in the elimination of approximately 18,000 positions worldwide. As of December 31, 2015 , we have eliminated approximately 17,000 positions. As a result of these workforce reductions, we recorded a charge for severance expense of $436 million during 2015 , net of related employee benefit plan gains of $10 million . As of December 31, 2015 , we have made payments totaling $365 million relating to workforce reductions. We expect that substantially all of the accrued severance remaining will be paid by the middle of 2016. Contract termination costs: During 2015 , we incurred costs of $121 million to terminate or restructure various contracts, primarily in North America. This includes the accrual for costs to settle leases on closed facilities and certain equipment, and other estimated exit costs, and is net of expected sublease income. This also includes costs to terminate or restructure certain take-or-pay supply contracts related to the purchase of materials used in our pressure pumping operations in North America, including the write-off of $14 million of prepayments made in 2014. As of December 31, 2015 , we have made payments totaling $81 million relating to contract termination costs. Impairment of buildings and improvements: We are consolidating facilities and shutting down certain operations and as a result are closing and abandoning or selling certain facilities, both owned and leased. During 2015 , we recognized $82 million of impairment charges related to facilities primarily in North America and Latin America. For leased facilities, this charge includes the impairment of the leasehold improvements made to those facilities. Impairment of machinery and equipment: We are exiting or substantially downsizing our presence in select markets primarily in our pressure pumping product line in North America and Latin America. During 2015 , we recognized $191 million of impairment losses to adjust the carrying value of certain machinery and equipment to its fair value, net of costs to dispose. We are currently in the process of disposing of this machinery and equipment through sale or scrap. OTHER CHARGES In addition to the matters described above, during 2015 , we also recorded charges of $194 million , of which $37 million is reported in cost of sales and $157 million is reported in cost of services, to write-down the carrying value of certain inventory. The write-down, primarily in North America, includes lower of cost or market adjustments due to the significant decline in activity and related prices for our products coupled with declines in replacement costs. In addition, the adjustments include provisions for excess inventory levels based on estimates of current and future market demand. The product lines impacted are primarily pressure pumping and drilling and completion fluids.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-based compensation	STOCK-BASED COMPENSATION Stock-based compensation cost is measured at the date of grant based on the calculated fair value of the award and is generally recognized on a straight-line basis over the vesting period of the equity grant. The compensation cost is determined based on awards ultimately expected to vest; therefore, we have reduced the cost for estimated forfeitures based on historical forfeiture rates. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods to reflect actual forfeitures. There were no stock-based compensation costs capitalized as the amounts were not material. Stock-based compensation costs are as follows for the years ended December 31: 2015 2014 2013 Stock-based compensation cost $ 120 $ 122 $ 115 Tax benefit (28 ) (26 ) (24 ) Stock-based compensation cost, net of tax $ 92 $ 96 $ 91 For our stock options and restricted stock awards and units, we currently have 60.7 million shares authorized for issuance and as of December 31, 2015 , approximately 21.3 million shares were available for future grants. Our policy is to issue new shares for exercises of stock options, when restricted stock awards are granted, at vesting of restricted stock units and for issuances under the employee stock purchase plan. Stock Options Our stock option plans provide for the issuance of stock options to directors, officers and other key employees at an exercise price equal to the fair market value of the stock at the date of grant. Although subject to the terms of the stock option agreement, substantially all of the stock options become exercisable in three equal annual installments, beginning a year from the date of grant, and generally expire ten years from the date of grant. The stock option plans provide for the acceleration of vesting upon the employee’s retirement; therefore, the service period is reduced for employees that are or will become retirement eligible during the vesting period, and accordingly, the recognition of compensation expense for these employees is accelerated. No stock options were granted in 2015. The fair value of each stock option granted is estimated using the Black-Scholes option pricing model. The following table presents the weighted average assumptions used in the option pricing model for options granted. The expected life of the options represents the period of time the options are expected to be outstanding. The expected life is based on our historical exercise trends and post-vest termination data incorporated into a forward-looking stock price model. The expected volatility is based on our implied volatility, which is the volatility forecast that is implied by the prices of actively traded options to purchase our stock observed in the market. The risk-free interest rate is based on the observed U.S. Treasury yield curve in effect at the time the options were granted. The dividend yield is based on our history of dividend payouts. 2014 2013 Expected life (years) 4.6 5.2 Risk-free interest rate 1.5 % 1.3 % Volatility 31.9 % 36.0 % Dividend yield 1.0 % 1.3 % Weighted average fair value per share at grant date $ 16.81 $ 13.79 The following table presents the changes in stock options outstanding and related information (in thousands, except per option prices): Number of Options Weighted Average Exercise Price Per Option Outstanding at December 31, 2014 9,737 $ 53.80 Granted — — Exercised (873 ) 44.25 Forfeited (124 ) 53.90 Expired (138 ) 67.85 Outstanding at December 31, 2015 8,602 $ 54.56 Exercisable at December 31, 2015 7,363 $ 54.46 The weighted average remaining contractual term for options outstanding and options exercisable at December 31, 2015 were 4.7 years and 4.2 years, respectively. The total intrinsic value of stock options (defined as the amount by which the market price of our common stock on the date of exercise exceeds the exercise price of the option) exercised in 2015 , 2014 and 2013 was $15 million , $70 million and $11 million , respectively. The income tax benefit realized from stock options exercised was $3.8 million , $19.6 million and $2.0 million in 2015 , 2014 and 2013 , respectively. The total fair value of options vested in 2015 , 2014 and 2013 was $24 million , $29 million and $31 million , respectively. As of December 31, 2015 , there was $5 million of total unrecognized compensation cost related to unvested stock options, which is expected to be recognized over a weighted average period of one year. The total intrinsic value of stock options outstanding at December 31, 2015 was $15.1 million , of which $14.8 million relates to options vested and exercisable. The intrinsic value for stock options outstanding is calculated as the amount by which the quoted price of $46.15 of our common stock as of the end of 2015 exceeds the exercise price of the options. Restricted Stock Awards and Units In addition to stock options, our officers, directors and key employees may be granted restricted stock awards (“RSA”), which is an award of common stock with no exercise price, or restricted stock units (“RSU”), where each unit represents the right to receive, at the end of a stipulated period, one unrestricted share of stock with no exercise price. RSAs and RSUs are subject to cliff or graded vesting, generally ranging over a three year period, or over a one year period for non-employee directors. We determine the fair value of restricted stock awards and restricted stock units based on the market price of our common stock on the date of grant. The following table presents the combined changes of RSAs and RSUs and related information (in thousands, except per award/unit prices): Number of Awards and Units Weighted Average Grant Date Fair Value Per Award/Unit Unvested balance at December 31, 2014 2,732 $ 57.88 Granted 2,314 57.37 Vested (1,299 ) 55.09 Forfeited (391 ) 54.62 Unvested balance at December 31, 2015 3,356 $ 58.99 The weighted average grant date fair value per share for RSAs and RSUs granted in 2015 , 2014 and 2013 was $57.37 , $69.67 and $45.58 , respectively. The total fair value of RSAs and RSUs vested in 2015 , 2014 and 2013 was $72 million , $60 million and $58 million , respectively. As of December 31, 2015 , there was $117 million of total unrecognized compensation cost related to unvested RSAs and RSUs, which is expected to be recognized over a weighted average period of two years. Employee Stock Purchase Plan The Employee Stock Purchase Plan (“ESPP”) provides for eligible employees to purchase shares on an after-tax basis in an amount between 1% and 10% of their annual pay: (i) on June 30 of each year at a 15% discount of the fair market value of our common stock on January 1 or June 30, whichever is lower, and (ii) on December 31 of each year at a 15% discount of the fair market value of our common stock on July 1 or December 31, whichever is lower. An employee may not contribute more than $5,000 in either of the six-month measurement periods described above or $10,000 annually. We currently have 30.5 million shares authorized for issuance, and at December 31, 2015 , there were 4.2 million shares reserved for future issuance. Compensation cost for the years ended December 31, was calculated using the Black-Scholes option pricing model with the following assumptions: 2015 2014 2013 Expected life (years) 0.5 0.5 0.5 Risk-free interest rate 0.1 % 0.03 % 0.1 % Volatility 30.9 % 24.7 % 30.3 % Dividend yield 1.2 % 1.0 % 1.4 % Fair value per share of the 15% cash discount $ 8.79 $ 9.72 $ 6.45 Fair value per share of the look-back provision 4.97 4.39 3.58 Total weighted average fair value per share at grant date $ 13.76 $ 14.11 $ 10.03 We calculated estimated volatility using historical daily prices based on the expected life of the stock purchase plan. The risk-free interest rate is based on the observed U.S. Treasury yield curve in effect at the time the ESPP shares were granted. The dividend yield is based on our history of dividend payouts.

This included a $360 million tax benefit resulting from the reversal of a deferred tax liability related to our decision to indefinitely reinvest the earnings of certain foreign subsidiaries which was made in conjunction with the reorganization that occurred during the fourth quarter of 2013. Due to the fact that these undistributed foreign earnings are no longer a source of future income against which the foreign tax credits will be utilized, we also recognized a tax charge of $342 million to record a valuation allowance against certain foreign tax credit carryforwards. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, as well as operating loss and tax credit carryforwards. The tax effects of our temporary differences and carryforwards are as follows at December 31: 2015 2014 Deferred tax assets: Receivables $ 84 $ 65 Inventory 253 376 Employee benefits 143 106 Other accrued expenses 141 173 Operating loss carryforwards 1,153 493 Tax credit carryforwards 458 481 Other 112 104 Subtotal 2,344 1,798 Valuation allowances (1,210 ) (1,051 ) Total 1,134 747 Deferred tax liabilities: Goodwill and other intangibles 272 334 Property 47 459 Undistributed earnings of foreign subsidiaries 21 26 Other 35 16 Total 375 835 Net deferred tax asset (liability) $ 759 $ (88 ) We record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character in the future and in the appropriate taxing jurisdictions. At December 31, 2015 , valuation allowances totaled $1,210 million consisting of $672 million for operating loss carryforwards, $425 million for foreign tax credit carryforwards, and $113 million for other deferred tax assets in various jurisdictions. There are $481 million of deferred tax assets related to operating loss carryforwards without a valuation allowance as we expect that the deferred tax assets will be realized within the carryforward period. The majority of these deferred tax assets will expire in varying amounts over the next twenty years. We have provided relevant U.S. and foreign taxes for the anticipated repatriation of certain earnings of our foreign subsidiaries. We consider the undistributed earnings of our foreign subsidiaries above the amount for which taxes have already been provided to be indefinitely reinvested, as we have no current intention to repatriate these earnings. As of December 31, 2015 , the cumulative amount of earnings upon which the U.S. income taxes have not been provided is approximately $5.6 billion . These additional foreign earnings could become subject to additional tax, if remitted, or deemed remitted, as a dividend. Computation of the potential deferred tax liability associated with these undistributed earnings and any other basis differences, is not practicable. At December 31, 2015 , we had approximately $126 million of foreign tax credits which may be carried forward indefinitely under applicable foreign law, and $310 million of foreign tax credits and $22 million of other credits which expire in 2016 through 2035 under U.S. tax law. At December 31, 2015 , we had $312 million of tax liabilities for total gross unrecognized tax benefits related to uncertain tax positions, which includes liabilities for interest and penalties of $30 million and $21 million , respectively. If we were to prevail on all uncertain tax positions, the net effect would be an increase to our income tax benefit of approximately $289 million . The remaining approximately $23 million is offset by deferred tax assets that represent tax benefits that would be received in different taxing jurisdictions in the event that we did not prevail on all uncertain tax positions. The following table presents the changes in our gross unrecognized tax benefits and associated interest and penalties included in the consolidated balance sheets. Gross Unrecognized Tax Benefits, Excluding Interest and Penalties Interest and Penalties Total Gross Unrecognized Tax Benefits Balance at December 31, 2012 $ 196 $ 71 $ 267 Increase (decrease) in prior year tax positions 20 (2 ) 18 Increase in current year tax positions 44 1 45 Decrease related to settlements with taxing authorities (15 ) (4 ) (19 ) Decrease related to lapse of statute of limitations (17 ) (10 ) (27 ) Decrease due to effects of foreign currency translation — (2 ) (2 ) Balance at December 31, 2013 228 54 282 (Decrease) increase in prior year tax positions (7 ) 1 (6 ) Increase in current year tax positions 39 2 41 Decrease related to settlements with taxing authorities (5 ) (1 ) (6 ) Decrease related to lapse of statute of limitations (6 ) (3 ) (9 ) Decrease due to effects of foreign currency translation (7 ) (4 ) (11 ) Balance at December 31, 2014 242 49 291 Increase in prior year tax positions 19 15 34 Increase in current year tax positions 26 1 27 Decrease related to settlements with taxing authorities (8 ) (2 ) (10 ) Decrease related to lapse of statute of limitations (11 ) (7 ) (18 ) Decrease due to effects of foreign currency translation (8 ) (4 ) (12 ) Balance at December 31, 2015 $ 260 $ 52 $ 312 It is expected that the amount of unrecognized tax benefits will change in the next twelve months due to expiring statutes, audit activity, tax payments, competent authority proceedings related to transfer pricing or final decisions in matters that are the subject of litigation in various taxing jurisdictions in which we operate. At December 31, 2015 , we had approximately $80 million of tax liabilities, net of $13 million of tax assets, related to uncertain tax positions, each of which are individually insignificant, and each of which are reasonably possible of being settled within the next twelve months. At December 31, 2015 , approximately $219 million of tax liabilities for total gross unrecognized tax benefits were included in the noncurrent portion of our income tax liabilities, for which the settlement period cannot be determined; however, it is not expected to be within the next twelve months. We operate in more than 80 countries and are subject to income taxes in most taxing jurisdictions in which we operate. The following table summarizes the earliest tax years that remain subject to examination by the major taxing jurisdictions in which we operate. In addition to the U.S., we include foreign jurisdictions that we project to have the highest tax liability for 2016.

The fair value was determined using quoted period end market prices. At December 31, 2015 , we have a committed revolving credit facility (“credit facility”) with commercial banks and a related commercial paper program under which the maximum combined borrowing at any time under both the credit facility and the commercial paper program is $2.5 billion . The credit facility matures in September 2016 . As of December 31, 2015 , we were in compliance with all of the credit facility's covenants, and there were no direct borrowings under the credit facility during 2015 . Under the commercial paper program, we may issue from time to time up to $2.5 billion in commercial paper with maturities of no more than 270 days. The amount available to borrow under the credit facility is reduced by the amount of any commercial paper outstanding. At December 31, 2015 , we had no borrowings outstanding under the commercial paper program. Maturities of debt at December 31, 2015 are as follows: 2016 - $151 million ; 2017 - $24 million ; 2018 - $1,024 million ; 2019 - $22 million ; 2020 - $12 million ; and $2,808 million thereafter.

Compensation and Retirement Disclosure [Abstract]
Employee benefit plans	EMPLOYEE BENEFIT PLANS DEFINED BENEFIT PLANS We have both funded and unfunded noncontributory defined benefit pension plans (“Pension Benefits”) covering certain employees primarily in the U.S., the U.K., Germany and Canada. Under the provisions of the U.S. qualified pension plan (the “U.S. Pension Plan”), a hypothetical cash balance account is established for each participant. Such accounts receive quarterly credits based on a percentage according to the employee’s age on the last day of the quarter applied to quarterly eligible compensation and interest credits based on the balance in the account on the last day of the quarter. The U.K. and Canada plans are frozen for the majority of the participants; therefore, we do not accrue benefits for those participants. The Germany pension plan is an unfunded plan where benefits are based on creditable years of service, creditable pay and accrual rates. We also provide certain postretirement health care benefits (“Other Postretirement Benefits”), through an unfunded plan, to a closed group of U.S. employees who retire and have met certain age and service requirements. During 2015, as a result of the workforce reductions stemming from our restructuring activities, we remeasured certain pension and other postretirement benefit obligations, which resulted in reductions in our projected benefit obligations of $28 million , and curtailment gains of $18 million . Funded Status Below is the reconciliation of the beginning and ending balances of benefit obligations, fair value of plan assets and the funded status of our plans.

The projected benefit obligation (“PBO”) for pension benefits represents the actuarial present value of benefits attributed to employee services and compensation and includes an assumption about future compensation levels. The accumulated benefit obligation (“ABO”) is the actuarial present value of pension benefits attributed to employee service to date and present compensation levels. The ABO differs from the PBO in that the ABO does not include any assumptions about future compensation levels. Information for the plans with ABOs in excess of plan assets is as follows at December 31: U.S. Pension Benefits Non-U.S. Pension Benefits Other Postretirement Benefits 2015 2014 2015 2014 2015 2014 Projected benefit obligation $ 735 $ 19 $ 149 $ 164 n/a n/a Accumulated benefit obligation $ 681 $ 18 $ 114 $ 125 $ 107 $ 122 Fair value of plan assets $ 595 $ — $ 12 $ 17 n/a n/a Weighted average assumptions used to determine benefit obligations for these plans are as follows for the years ended December 31: U.S. Pension Benefits Non-U.S. Pension Benefits Other Postretirement Benefits 2015 2014 2015 2014 2015 2014 Discount rate 4.2 % 3.8 % 3.7 % 3.5 % 3.7 % 3.4 % Rate of compensation increase 5.9 % 5.8 % 4.1 % 4.1 % n/a n/a Social security increase 2.8 % 2.8 % 2.2 % 2.1 % n/a n/a The development of the discount rate for our U.S. plans and substantially all non-U.S. plans was based on a bond matching model, whereby a hypothetical bond portfolio of high-quality, fixed-income securities is selected that will match the cash flows underlying the projected benefit obligation. Accumulated Other Comprehensive Loss The amount recorded before-tax in accumulated other comprehensive loss related to employee benefit plans consists of the following at December 31: U.S. Pension Benefits Non-U.S. Pension Benefits Other Postretirement Benefits 2015 2014 2015 2014 2015 2014 Net actuarial loss $ 191 $ 174 $ 229 $ 231 $ 10 $ 25 Net prior service cost (credit) — 1 — — (54 ) (83 ) Total $ 191 $ 175 $ 229 $ 231 $ (44 ) $ (58 ) The estimated net actuarial loss and prior service cost for the defined benefit pension plans that will be amortized from accumulated other comprehensive loss and included in net periodic benefit cost in 2016 are $17 million and $0.3 million , respectively. The estimated prior service credit for the other postretirement benefits that will be amortized from accumulated other comprehensive loss and included in net periodic benefit cost in 2016 is $9 million . No amortization of the net actuarial loss for the other postretirement benefits from accumulated other comprehensive loss is expected in 2016 .

This includes considering the trusts’ asset allocation and the expected returns likely to be earned over the life of the plans. Health Care Cost Trend Rates Assumed health care cost trend rates can have a significant effect on the amounts reported for other postretirement benefits. As of December 31, 2015 , the health care cost trend rate was 7.3% for employees under age 65, declining gradually each successive year until it reaches 4.5% . A one percentage point change in assumed health care cost trend rates would have had the following effects on 2015 : One Percentage Point Increase One Percentage Point Decrease Effect on total of service and interest cost components $ 0.1 $ (0.1 ) Effect on postretirement welfare benefit obligation $ 0.9 $ (1.2 ) Plan Assets We have investment committees that meet regularly to review the portfolio returns and to determine asset-mix targets based on asset/liability studies. Third-party investment consultants assist such committees in developing asset allocation strategies to determine our expected rates of return and expected risk for various investment portfolios. The investment committees considered these strategies in the formal establishment of the current asset-mix targets based on the projected risk and return levels for all major asset classes. The majority of investments are held in the form of units of funds. The funds hold underlying securities and are redeemable as of the measurement date. Investments in equities and fixed-income funds are generally measured at fair value based on daily closing prices provided by active exchanges or on the basis of observable, market-based inputs. Investments in hedge funds are generally measured at fair value on the basis of their net asset values, which are provided by the investment sponsor or third party administrator. The fair values of private equity investments and real estate funds are based on appraised values developed using comparable market transactions or discounted cash flows. U.S. Pension Plan The investment policy of the U.S. Pension Plan was developed after examining the historical relationships of risk and return among asset classes and the relationship between the expected behavior of the U.S. Plan’s assets and liabilities. The investment policy of the U.S. Plan is designed to provide the greatest probability of meeting or exceeding the U.S. Plan’s objectives at the lowest possible risk. In evaluating risk, the investment committee for the U.S. Pension Plan (“U.S. Committee”) reviews the long-term characteristics of various asset classes, focusing on balancing risk with expected return. Accordingly, the U.S. Committee selected the following six asset classes as allowable investments for the assets of the U.S. Pension Plan: U.S. equities, non-U.S. equities, global fixed-income securities, real estate, hedge funds and private equity. The table below presents the fair value of the assets in the U.S. Pension Plan by asset category and by valuation technique at December 31: 2015 2014 Asset Category Total Asset Value Level One Level Two Level Three Total Asset Value Level One Level Two Level Three Cash and Cash Equivalents $ 16 $ 12 $ 4 $ — $ 3 $ — $ 3 $ — Fixed Income (1) 109 — 109 — 125 — 125 — Non-U.S. Equity (2) 129 31 98 — 148 30 118 — U.S. Equity (3) 129 — 129 — 169 — 169 — Hedge Funds (4) 152 — — 152 164 — — 164 Real Estate Funds (5) 10 — — 10 10 — — 10 Real Estate Investment Trust Equity 9 — 9 — 8 — 8 — Private Equity Fund (6) 41 — — 41 21 — — 21 Total $ 595 $ 43 $ 349 $ 203 $ 648 $ 30 $ 423 $ 195 (1) A multi-manager strategy investing in fixed income securities and funds.

Non-U.S. Pension Plans The investment policies of our pension plans with plan assets, which are primarily in Canada and the U.K., (the “Non-U.S. Plans”), cover the asset allocations that the governing boards believe are the most appropriate for these Non-U.S. Plans in the long-term, taking into account the nature of the liabilities they expect to incur. The suitability of asset allocations and investment policies are reviewed periodically to ensure alignment with plan liabilities.

In 2016 , we expect to contribute between $65 million and $75 million to our funded and unfunded pension plans. In 2016 , we also expect to make benefit payments related to other postretirement benefits of between $15 million and $20 million . The following table presents the expected benefit payments over the next ten years. The U.S. and non-U.S. pension benefit payments are made by the respective pension trust funds. Year U.S. Pension Benefits Non-U.S. Pension Benefits Other Postretirement Benefits 2016 $ 47 $ 24 $ 17 2017 $ 41 $ 25 $ 13 2018 $ 43 $ 28 $ 11 2019 $ 46 $ 33 $ 10 2020 $ 48 $ 32 $ 10 2021-2025 $ 280 $ 204 $ 43 DEFINED CONTRIBUTION PLANS During the periods reported, generally all of our U.S. employees were eligible to participate in our sponsored 401(k) plan (“Thrift Plan”). The Thrift Plan allows eligible employees to elect to contribute portions of their salaries to an investment trust. Employee contributions are matched by the Company in cash at the rate of $1.00 per $1.00 employee contribution for the first 5% of the employee’s salary, and such contributions vest immediately. In addition, we make cash contributions for all eligible employees between 2% and 5% of their salary depending on the employee’s age. Such contributions are fully vested to the employee after three years of employment. The Thrift Plan provides several investment options, for which the employee has sole investment discretion. The Thrift Plan does not offer the Company's common stock as an investment option. Our contributions to the Thrift Plan and several other non-U.S. defined contribution plans amounted to $202 million , $263 million and $240 million in 2015 , 2014 and 2013 , respectively. For certain non-U.S. employees who are not eligible to participate in the Thrift Plan, we provide a non-qualified defined contribution international retirement plan that provides basically the same benefits as those provided in the Thrift Plan. In addition, we provide a non-qualified supplemental retirement plan (“SRP”) for certain officers and employees whose benefits under the Thrift Plans and/or the U.S. qualified pension plan are limited by federal tax law. The SRP also allows eligible employees to defer a portion of their eligible compensation and provides for employer matching and base contributions pursuant to limitations. Both non-qualified plans are invested through trusts, and the assets and corresponding liabilities are included in our consolidated balance sheets. Our contributions to these non-qualified plans amounted to $15 million , $17 million and $15 million in 2015 , 2014 and 2013 , respectively. In 2016 , we estimate we will contribute between $165 million and $180 million to all of our defined contribution plans. POSTEMPLOYMENT BENEFITS We provide certain postemployment disability income, medical and other benefits to substantially all qualifying former or inactive U.S. employees. Income benefits for long-term disability are provided through a fully-insured plan. The continuation of medical and other benefits while on disability (“Continuation Benefits”) are provided through a qualified self-insured plan. The accrued postemployment liability for Continuation Benefits at December 31, 2015 and 2014 was $34 million and $30 million , respectively, and is included in other liabilities in our consolidated balance sheets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES LEASES At December 31, 2015 , we had long-term non-cancelable operating leases covering certain facilities and equipment. The minimum annual rental commitments, net of amounts due under subleases, for each of the five years in the period ending December 31, 2020 are $183 million , $119 million , $65 million , $51 million and $21 million , respectively, and $151 million in the aggregate thereafter. Rent expense was $514 million , $747 million and $702 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. We did not enter into any significant capital leases during the three years ended December 31, 2015 . LITIGATION We are subject to a number of lawsuits and claims arising out of the conduct of our business. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. We record a liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated, including accruals for self-insured losses which are calculated based on historical claim data, specific loss development factors and other information. A range of total possible losses for all litigation matters cannot be reasonably estimated. Based on a consideration of all relevant facts and circumstances, we do not expect the ultimate outcome of any currently pending lawsuits or claims against us will have a material adverse effect on our financial position, results of operations or cash flows; however, there can be no assurance as to the ultimate outcome of these matters. We insure against risks arising from our business to the extent deemed prudent by our management and to the extent insurance is available, but no assurance can be given that the nature and amount of that insurance will be sufficient to fully indemnify us against liabilities arising out of pending or future legal proceedings or other claims. Most of our insurance policies contain deductibles or self-insured retentions in amounts we deem prudent and for which we are responsible for payment. In determining the amount of self-insurance, it is our policy to self-insure those losses that are predictable, measurable and recurring in nature, such as claims for automobile liability, general liability and workers compensation. The following lawsuits have been filed in Delaware in connection with our pending Merger with Halliburton: • On November 24, 2014, Gary Molenda, a purported shareholder of the Company, filed a class action lawsuit in the Court of Chancery of the State of Delaware ("Delaware Chancery Court") against Baker Hughes, the Company’s Board of Directors, Halliburton, and Red Tiger LLC, a wholly owned subsidiary of Halliburton (“Red Tiger” and together with all defendants, “Defendants”) styled Gary R. Molenda v. Baker Hughes, Inc., et al., Case No. 10390-CB. • On November 26, 2014, a second purported shareholder of the Company, Booth Family Trust, filed a substantially similar class action lawsuit in Delaware Chancery Court. • On December 1, 2014, New Jersey Building Laborers Annuity Fund and James Rice, two additional purported shareholders of the Company, filed substantially similar class action lawsuits in Delaware Chancery Court. • On December 10, 2014, a fifth purported shareholder of the Company, Iron Workers Mid-South Pension Fund, filed another substantially similar class action lawsuit in the Delaware Chancery Court. • On December 24, 2014, a sixth purported shareholder of the Company, Annette Shipp, filed another substantially similar class action lawsuit in the Delaware Chancery Court. All of the lawsuits make substantially similar claims. The plaintiffs generally allege that the members of the Company’s Board of Directors breached their fiduciary duties to our shareholders in connection with the Merger negotiations by entering into the Merger Agreement and by approving the Merger, and that the Company, Halliburton, and Red Tiger aided and abetted the purported breaches of fiduciary duties. More specifically, the lawsuits allege that the Merger Agreement provides inadequate consideration to our shareholders, that the process resulting in the Merger Agreement was flawed, that the Company’s directors engaged in self-dealing, and that certain provisions of the Merger Agreement improperly favor Halliburton and Red Tiger, precluding or impeding third parties from submitting potentially superior proposals, among other things. The lawsuit filed by Annettee Shipp also alleges that our Board of Directors failed to disclose material information concerning the proposed Merger in the preliminary registration statement on Form S-4. On January 7, 2015, James Rice amended his complaint, adding similar allegations regarding the disclosures in the preliminary registration statement on Form S-4. The lawsuits seek unspecified damages, injunctive relief enjoining the Merger, and rescission of the Merger Agreement, among other relief. On January 23, 2015, the Delaware lawsuits were consolidated under the caption In re Baker Hughes Inc. Stockholders Litigation, Consolidated C.A. No. 10390-CB (the "Consolidated Case"). Pursuant to the Court’s consolidation order, plaintiffs filed a consolidated complaint on February 4, 2015, which alleges substantially similar claims and seeks substantially similar relief to that raised in the six individual complaints, except that while Baker Hughes is named as a defendant, no claims are asserted against the Company. On March 18, 2015, the parties reached an agreement in principle to settle the Consolidated Case in exchange for the Company making certain additional disclosures. Those disclosures were contained in a Form 8-K filed with the SEC on March 18, 2015. The settlement remains subject to certain conditions, including consummation of the Merger, final documentation, and court approval. On November 26, 2014, a seventh class action challenging the Merger was filed by a purported shareholder of the Company in the United States District Court for the Southern District of Texas (Houston Division). The lawsuit, styled Marc Rovner v. Baker Hughes Inc., et al., Cause No. 4:14-cv-03416 (the "Rovner lawsuit"), asserts claims against the Company, most of our current Board of Directors, Halliburton, and Red Tiger. The lawsuit asserts substantially similar claims and seeks substantially similar relief as that sought in the Delaware lawsuits. On March 20, 2015, counsel for Mr. Rovner filed a notice of voluntary dismissal, and on March 23, 2015, the Court entered an order dismissing the Rovner lawsuit without prejudice. On October 9, 2014, our subsidiary filed a Request for Arbitration against a customer before the London Court of International Arbitration, pursuing claims for the non-payment of invoices for goods and services provided in an amount provisionally quantified to exceed $67.9 million . In our Request for Arbitration, we also noted that invoices in an amount exceeding $57 million had been issued to the customer, and would be added to the claim in the event that they became overdue. The due date for payment of all of these invoices has passed. On November 6, 2014, the customer filed its Response and Counterclaim, denying liability and counterclaiming damages for breach of contract of approximately $182 million . We deny any liability to the customer and intend to pursue our claims against the customer and defend the claims made under the counterclaim. The Parties have applied to the arbitration tribunal to extend the suspension of the arbitral proceedings to March 31, 2016, pending ongoing settlement discussions. No timetable for the conduct of the arbitration has yet been established. During 2014, we received customer notifications related to a possible equipment failure in a natural gas storage system in Northern Germany, which includes certain of our products. We are currently investigating the cause of the possible failure and, if necessary, possible repair and replacement options for our products. Similar products were utilized in other natural gas storage systems for this and other customers. The customer initiated arbitral proceedings against us on June 19, 2015, under the rules of the German Institute of Arbitration e.V. (DIS). The customer alleges damages of approximately $170 million plus interest at an annual rate of prime + 5% . A procedural schedule for the arbitration has not yet been set. In addition, on September 21, 2015, TRIUVA Kapitalverwaltungsgesellschaft mbH filed a lawsuit in the United States District Court for the Southern District of Texas, (Houston Division) against the Company and Baker Hughes Oilfield Operations, Inc. alleging that the plaintiff is the owner of gas storage caverns in Etzel, Germany in which the Company provided certain equipment in connection with the development of the gas storage caverns. The plaintiff further alleges that the Company supplied equipment that was either defectively designed or failed to warn of risks that the equipment posed, and that these alleged defects caused damage to the plaintiff’s property. The plaintiff seeks recovery of alleged compensatory and punitive damages of an unspecified amount, in addition to reasonable attorneys’ fees, court costs and pre-judgment and post-judgment interest. The allegations in this lawsuit are related to the claims made in the June 19, 2015 German arbitration referenced above. On December 15, 2015, the District Court entered an order staying the lawsuit in favor of the pending German Arbitration. At this time, we are not able to predict the outcome of these claims or whether either will have a material impact on our financial position, results of operations or cash flows. On August 31, 2015, a customer of one of the Company’s subsidiaries issued a Letter of Claim pursuant to a Construction and Engineering Contract. The customer has claimed $369 million plus loss of production resulting from a breach of contract related to five electric submersible pumps installed by the subsidiary in Europe. Investigation is ongoing as to the merits of the claim. At this time, we are not able to predict the outcome of this claim or whether it will have a material impact on our financial position, results of operations or cash flows. On October 30, 2015, Chieftain Sand and Proppant Barron, LLC initiated arbitration against our subsidiary, Baker Hughes Oilfield Operations, Inc., in the American Arbitration Association. The Claimant alleges that the Company failed to purchase the required sand tonnage for the contract year 2014-2015 and further alleges that the Company repudiated its yearly purchase obligations over the remaining contract term. The Claimant alleges damages of approximately $110 million plus interest, attorneys’ fees and costs. A procedural schedule for the arbitrations has not yet been set. The Company intends to vigorously defend the claim. At this time, we are not able to predict the outcome of this claim or whether it will have a material impact on our financial position, results of operations or cash flows. During the second quarter of 2014, we recorded a charge of $62 million related to previously disclosed litigation settlements for wage and hour lawsuits. A portion of this settlement was to be paid on a claims made basis and during the second quarter of 2015, the date passed by which the class members could file a claim under this provision of the settlement agreement. The amount of claims made was less than estimated and, accordingly, we reduced the accrual by approximately $13 million , which was recorded as an adjustment for litigation settlements during the second quarter of 2015. On April 30, 2015, a class and collective action lawsuit alleging that we failed to pay a nationwide class of workers overtime in compliance with the Fair Labor Standards Act and North Dakota law was filed titled Williams et al. v. Baker Hughes Oilfield Operations, Inc. in the U.S. District Court for the District of North Dakota. We are evaluating the background facts and at this time are not able to predict the outcome of this lawsuit or whether it will have a material impact on our financial position, results of operations or cash flows. On July 31, 2015, Rapid Completions LLC filed a lawsuit in federal court in the Eastern District of Texas against Baker Hughes Incorporated, Baker Hughes Oilfield Operations, Inc., and others claiming infringement of U.S. Patent Nos. 6,907,936; 7,134,505; 7,543,634; 7,861,774; and 8,657,009. On August 6, 2015, Rapid Completions amended its complaint to allege infringement of U.S. Patent No. 9,074,451. On September 17, 2015, Rapid Completions LLC and Packers Plus Energy Services Inc., sued Baker Hughes Canada Company in the Canada Federal Court on related Canadian patent 2,412,072. These patents relate primarily to certain specific downhole completions equipment. The case is set for a jury trial on September 25, 2017, in Tyler, Texas. Plaintiff has requested a permanent injunction against further alleged infringement, damages in an unspecified amount, supplemental and enhanced damages, and additional relief such as attorney’s fees and costs. At this time, we are not able to predict the outcome of these claims or whether either will have a material impact on our financial position, results of operations or cash flows. On May 30, 2013, we received a Civil Investigative Demand ("CID") from the U.S. Department of Justice ("DOJ") pursuant to the Antitrust Civil Process Act. The CID seeks documents and information from us for the period from May 29, 2011 through the date of the CID in connection with a DOJ investigation related to pressure pumping services in the U.S. We are working with the DOJ to provide the requested documents and information. We are not able to predict what action, if any, might be taken in the future by the DOJ or other governmental authorities as a result of the investigation. ENVIRONMENTAL MATTERS Our past and present operations include activities that are subject to extensive domestic (including U.S. federal, state and local) and international environmental regulations with regard to air, land and water quality and other environmental matters. Our environmental procedures, policies and practices are designed to ensure compliance with existing laws and regulations and to minimize the possibility of significant environmental damage. We are involved in voluntary remediation projects at certain of our facilities. On rare occasions, remediation activities are conducted as specified by a government agency-issued consent decree or agreed order. Remediation costs are accrued based on estimates of probable exposure using currently available facts, existing environmental permits, technology and presently enacted laws and regulations. Remediation cost estimates include direct costs related to the environmental investigation, external consulting activities, governmental oversight fees, treatment equipment and costs associated with long-term operation, maintenance and monitoring of a remediation project. We have also been identified as a potentially responsible party (“PRP”) in remedial activities related to various Superfund sites. In these instances, we participate in the process set out in the Joint Participation and Defense Agreement to negotiate with government agencies, identify other PRPs, and determine each PRP’s allocation and estimate remediation costs. We have accrued what we believe to be our pro-rata share of the total estimated cost of remediation and associated management of these Superfund sites. This share is based upon the ratio that the estimated volume of waste we contributed to the site to the total estimated volume of waste disposed at the site. Applicable U.S. federal law imposes joint and several liability on each PRP for the cleanup of these sites leaving us with the uncertainty that we may be responsible for the remediation cost attributable to other PRPs who are unable to pay their share. No accrual has been made under the joint and several liability concept for those Superfund sites where our participation is de minimis since we believe that the probability that we will have to pay material costs above our volumetric share is remote. We believe there are other PRPs who have greater involvement on a volumetric calculation basis, who have substantial assets and who may be reasonably expected to pay their share of the cost of remediation. For those Superfund sites where we are a significant PRP, remediation costs are estimated to include recalcitrant parties. In some cases, we have insurance coverage or contractual indemnities from third parties to cover a portion of the ultimate liability. Our total accrual for environmental remediation is $35 million and $35 million , which includes accruals of $2 million and $3 million for the various Superfund sites, at December 31, 2015 and 2014 , respectively. The determination of the required accruals for remediation costs is subject to uncertainty, including the evolving nature of environmental regulations and the difficulty in estimating the extent and type of remediation activity that is necessary. OTHER In the normal course of business with customers, vendors and others, we have entered into off-balance sheet arrangements, such as surety bonds for performance, letters of credit and other bank issued guarantees, which totaled approximately $1.2 billion at December 31, 2015 . It is not practicable to estimate the fair value of these financial instruments. None of the off-balance sheet arrangements either has, or is likely to have, a material effect on our consolidated financial statements. We also had commitments outstanding for purchase obligations related to capital expenditures, inventory and services under contracts, for each of the five years in the period ending December 31, 2020 of $202 million , $187 million , $162 million , $124 million and $106 million , respectively, and $67 million in the aggregate thereafter.

Significant Accounting Policies - (Policies)	12 Months Ended

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Baker Hughes Incorporated (“Baker Hughes,” “Company,” “we,” “our,” or “us,”) is a leading supplier of oilfield services, products, technology and systems used in the worldwide oil and natural gas industry. We also provide products and services for other businesses including downstream chemicals, and process and pipeline services.
Basis of Presentation	Basis of Presentation Our consolidated financial statements are prepared in conformity with United States generally accepted accounting principles ("GAAP"). The consolidated financial statements include the accounts of Baker Hughes and all of our subsidiaries where we exercise control. For investments in subsidiaries that are not wholly-owned, but where we exercise control, the equity held by the minority owners and their portions of net income (loss) are reflected as noncontrolling interests. Investments over which we have the ability to exercise significant influence over operating and financial policies, but do not hold a controlling interest, are accounted for using the equity method of accounting. Intercompany accounts and transactions have been eliminated in consolidation. In the Notes to Consolidated Financial Statements, all dollar and share amounts in tabulations are in millions of dollars and shares, respectively, unless otherwise indicated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, disclosure of any contingent assets or liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We base our estimates and judgments on historical experience and on various other assumptions and information that are believed to be reasonable under the circumstances. Estimates and assumptions about future events and their effects cannot be perceived with certainty, and accordingly, these estimates may change as new events occur, as more experience is acquired, as additional information is obtained and as our operating environment changes. While we believe that the estimates and assumptions used in the preparation of the consolidated financial statements are appropriate, actual results could differ from those estimates. Estimates are used for, but are not limited to, determining the following: allowance for doubtful accounts and inventory valuation reserves; recoverability of long-lived assets; useful lives used in depreciation and amortization; income taxes and related valuation allowances; accruals for contingencies; actuarial assumptions to determine costs and liabilities related to employee benefit plans; stock-based compensation expense and the fair value of assets acquired and liabilities assumed in acquisitions.
Revenue Recognition	Revenue Recognition Our products and services are sold based upon purchase orders, contracts or other agreements with the customer that include fixed or determinable prices and that do not include right of return or other similar provisions or other significant post-delivery obligations. We recognize revenue for products sold upon delivery, when title passes, when collectability is reasonably assured and when there are no further significant obligations for future performance. Provisions for estimated warranty returns or similar arrangements are made at the time the related revenue is recognized. Revenue for services is recognized as the services are rendered and when collectability is reasonably assured. Rates for services are typically priced on a per day, per distance drilled, per man hour or similar basis. In certain situations, revenue is generated from transactions that may include multiple products and services under one contract or agreement and which may be delivered to the customer over an extended period of time. Revenue from these arrangements is recognized in accordance with the above criteria and as each item or service is delivered based on their relative fair value.
Research and Engineering	Research and Engineering Research and engineering expenses are expensed as incurred and include costs associated with the research and development of new products and services and costs associated with sustaining engineering of existing products and services. Costs for research and development of new products and services were $347 million , $430 million and $370 million for the years ended December 31, 2015 , 2014 and 2013 , respectively.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash equivalents include only those investments with an original maturity of three months or less. We maintain cash deposits with financial institutions that may exceed federally insured limits. We monitor the credit ratings and our concentration of risk with these financial institutions on a continuing basis to safeguard our cash deposits.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts We establish an allowance for doubtful accounts based on various factors including the payment history and financial condition of our customers and the economic environment. Provisions for doubtful accounts are recorded based on the aging status of the customer accounts or when it becomes evident that the customer will not make the required payments at either contractual due dates or in the future. Provision for doubtful accounts recorded in cost of sales was $193 million , $102 million and $75 million for the years ended December 31, 2015 , 2014 and 2013 , respectively.
Concentration Risk, Credit Risk	Concentration of Credit Risk We grant credit to our customers who primarily operate in the oil and natural gas industry. Although this concentration affects our overall exposure to credit risk, our trade receivables are spread over a diverse group of customers across many countries, which mitigates this risk. We perform periodic credit evaluations of our customers’ financial condition, including monitoring our customers’ payment history and current credit worthiness to manage this risk. We do not generally require collateral in support of our trade receivables, but we may require payment in advance or security in the form of a letter of credit or bank guarantee. During 2015, 2014 and 2013, no individual customer accounted for more than 10% of our consolidated revenue.
Inventories	Inventories Inventories are stated at the lower of cost or market. Cost is determined using the average cost method, and includes the cost of materials, labor and manufacturing overhead. As necessary, we record provisions and maintain reserves for excess, slow moving and obsolete inventory. To determine these reserve amounts, we regularly review inventory quantities on hand and compare them to estimates of future product demand, market conditions, production requirements and technological developments.
Property, Plant and Equipment and Accumulated Depreciation	Property, Plant and Equipment and Accumulated Depreciation Property, plant and equipment (“PP&E”) is stated at cost less accumulated depreciation, which is generally provided by using the straight-line method over the estimated useful lives of the individual assets. Significant improvements and betterments are capitalized if they extend the useful life of the asset. We manufacture a substantial portion of our tools and equipment and the cost of these items, which includes direct and indirect manufacturing costs, is capitalized and carried in inventory until it is completed. When complete, the cost is reflected in capital expenditures and is classified as machinery, equipment and other in PP&E. Maintenance and repairs are charged to expense as incurred. Upon sale or other disposition, the applicable amounts of asset cost and accumulated depreciation are removed from the balance sheet and the net amount, less proceeds from disposal, is charged or credited to income. The capitalized costs of computer software developed or purchased for internal use are classified in machinery, equipment and other.
Goodwill, Intangible Assets and Amortization	Goodwill, Intangible Assets and Amortization Goodwill is the excess of the consideration transferred over the fair value of the tangible and identifiable intangible assets and liabilities recognized in acquisitions. Goodwill and intangible assets with indefinite lives are not amortized. Intangible assets with finite useful lives are amortized on a basis that reflects the pattern in which the economic benefits of the intangible assets are realized, which is generally on a straight-line basis over the asset’s estimated useful life.
Impairment of PP&E, Goodwill, Intangibles and Other Long Lived Assets	Impairment of PP&E, Intangibles, Other Long-lived Assets and Goodwill We review PP&E, intangible assets and certain other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable and at least annually for certain intangible assets. The determination of recoverability is made based upon the estimated undiscounted future net cash flows. The amount of impairment loss, if any, is determined by comparing the fair value, as determined by a discounted cash flow analysis, with the carrying value of the related assets. We perform an annual impairment test of goodwill for each of our reporting units as of October 1, or more frequently if an event occurs or circumstances change to indicate that it is more likely than not that an impairment may exist. Our reporting units are based on our organizational and reporting structure and are the same as our five reportable segments. Corporate and other assets and liabilities are allocated to the reporting units to the extent that they relate to the operations of those reporting units in determining their carrying amount. When performing the annual impairment test we have the option of first performing a qualitative assessment to determine the existence of events and circumstances that would lead to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If such a conclusion is reached, we would then be required to perform a quantitative impairment assessment of goodwill. However, if the assessment leads to a determination that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then no further assessments are required. In 2015 and 2014, we performed a qualitative assessment for our annual goodwill impairment test. In 2013, a quantitative assessment for the determination of impairment was made by comparing the carrying amount of each reporting unit with its fair value, which is generally calculated using a combination of market, comparable transaction and discounted cash flow approaches. In performing our annual goodwill impairment analysis for 2015, our qualitative assessment included consideration of current industry and market conditions and circumstances as well as any mitigating factors that would most affect the fair value of the Company and its reporting units. Among those mitigating factors, we considered the value of the consideration to be received at closing of the Merger (as defined below), based on the terms of the Merger Agreement (as defined below), compared to the carrying value of the Company and its reporting units. Based on our assessment and consideration of the totality of the facts and circumstances, including our business environment in the fourth quarter of 2015, we determined that it is not more likely than not that the fair value of the Company or any of its reporting units is less than their respective carrying amounts; however, a decline in our stock price could require an impairment in future periods. As such, no impairments of goodwill were recorded for the year ended December 31, 2015, or any of the prior years included in the accompanying financial statements.
Income Taxes	Income Taxes We use the liability method in determining our provision and liabilities for our income taxes, under which current and deferred tax liabilities and assets are recorded in accordance with enacted tax laws and rates. Deferred tax liabilities and assets, which are computed on the estimated income tax effect of temporary differences between financial and tax bases in assets and liabilities, are determined using the tax rate expected to be in effect when taxes are actually paid or recovered. A valuation allowance to reduce deferred tax assets is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized. We intend to indefinitely reinvest certain earnings of our foreign subsidiaries in operations outside the U.S., and accordingly, we have not provided for U.S. income taxes on such earnings. We do provide for the U.S. and additional non-U.S. taxes on earnings anticipated to be repatriated from our non-U.S. subsidiaries. Our tax filings for various periods are subject to audit by tax authorities in most jurisdictions where we conduct business. These audits may result in assessments of additional taxes that are resolved with the authorities or through the courts. We have provided for the amounts we believe will ultimately result from these proceedings. In addition to the assessments that have been received from various tax authorities, we also provide for taxes for uncertain tax positions where formal assessments have not been received. We classify interest and penalties related to uncertain tax positions as income taxes in our financial statements.
Environmental Matters	Environmental Matters Estimated remediation costs are accrued using currently available facts, existing environmental permits, technology and enacted laws and regulations. Our cost estimates are developed based on internal evaluations and are not discounted. Accruals are recorded when it is probable that we will be obligated to pay for environmental site evaluation, remediation or related activities, and such costs can be reasonably estimated. As additional information becomes available, accruals are adjusted to reflect current cost estimates. Ongoing environmental compliance costs, such as obtaining environmental permits, installation of pollution control equipment and waste disposal are expensed as incurred. Where we have been identified as a potentially responsible party in a U.S. federal or state Comprehensive Environmental Response, Compensation and Liability Act (“Superfund”) site, we accrue our share of the estimated remediation costs of the site. This share is based on the ratio of the estimated volume of waste we contributed to the site to the total volume of waste disposed at the site.
Foreign Currency	Foreign Currency A number of our significant foreign subsidiaries have designated the local currency as their functional currency and, as such, gains and losses resulting from balance sheet translation of foreign operations are included as a separate component of accumulated other comprehensive loss within stockholders’ equity. Gains and losses from foreign currency transactions, such as those resulting from the settlement of receivables or payables in the non-functional currency, are included in marketing, general and administrative (“MG&A”) expenses in the consolidated statements of income (loss) as incurred. For those foreign subsidiaries that have designated the U.S. Dollar ("USD") as the functional currency, monetary assets and liabilities are remeasured at period-end exchange rates, and nonmonetary items are remeasured at historical exchange rates. Gains and losses resulting from this balance sheet remeasurement are also included in MG&A expenses as incurred. In 2015 and 2014, the Venezuelan government modified its currency exchange systems, which impacted the rate at which we could reasonably expect to exchange the Venezuelan Bolivars Fuertes ("BsF") for the U.S. Dollar. As a result of the change in the exchange rate, in 2015 and 2014, we recognized a foreign currency loss of approximately $5 million and $12 million , respectively, related to the remeasurement of our BsF denominated assets and liabilities. This loss was recorded in MG&A expenses. We believe any further devaluation of Venezuela's currency would not have a material impact on our financial position, results of operations or cash flows. In 2013, Venezuela's currency was devalued from the prior exchange rate of 4.3 BsF per USD to 6.3 BsF per USD. The impact of this devaluation was a loss of $23 million that was recorded in MG&A expenses.
Fair Value Measurement	Fair Value Measurement The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at a measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: • Level One: The use of quoted prices in active markets for identical financial instruments. • Level Two: The use of quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active or other inputs that are observable in the market or can be corroborated by observable market data. • Level Three: The use of significantly unobservable inputs that typically require the use of management's estimates of assumptions that market participants would use in pricing.
Financial Instruments	Financial Instruments Our financial instruments include cash and cash equivalents, accounts receivable, investments, accounts payable, short and long-term debt, and derivative financial instruments. Except for long-term debt, the estimated fair value of our financial instruments at December 31, 2015 and 2014 approximates their carrying value as reflected in our consolidated balance sheets. For further information on the fair value of our debt, see Note 12. "Indebtedness." We monitor our exposure to various business risks including commodity prices, foreign currency exchange rates and interest rates and regularly use derivative financial instruments to manage these risks. Our policies do not permit the use of derivative financial instruments for speculative purposes. At the inception of a new derivative, we designate the derivative as a hedge or we determine the derivative to be undesignated as a hedging instrument. We document the relationships between the hedging instruments and the hedged items, as well as our risk management objectives and strategy for undertaking various hedge transactions. We assess whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of the hedged item at both the inception of the hedge and on an ongoing basis. We have a program that utilizes foreign currency forward contracts to reduce the risks associated with the effects of certain foreign currency exposures. Under this program, our strategy is to have gains or losses on the foreign currency forward contracts mitigate the foreign currency transaction and translation gains or losses to the extent practical. These foreign currency exposures typically arise from changes in the value of assets and liabilities which are denominated in currencies other than the functional currency. Our foreign currency forward contracts generally settle in less than 180 days. We record all derivatives as of the end of our reporting period in our consolidated balance sheet at fair value. For those forward contracts designated as fair value hedging instruments or held as undesignated hedging instruments, we record the changes in fair value of the forward contracts in our consolidated statements of income (loss) along with the change in fair value of the hedged item. Changes in the fair value of forward contracts designated as cash flow hedging instruments are recognized in other comprehensive income until the hedged item is recognized in earnings. For derivatives designated as a cash flow hedge, the ineffective portion of that derivative's change in fair value is recognized in earnings. Recognized gains and losses on derivatives entered into to manage foreign currency exchange risk are included in MG&A expenses in the consolidated statements of income (loss). We had outstanding foreign currency forward contracts with notional amounts aggregating $499 million and $580 million to hedge exposure to currency fluctuations in various foreign currencies at December 31, 2015 and 2014 , respectively. Based on quoted market prices as of December 31, 2015 or 2014 for forward contracts with similar terms and maturity dates, we recorded losses of $1 million and $11 million , respectively, to adjust these forward contracts to their fair market value.
New Accounting Accounting Standards Update	New Accounting Standards Updates In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers . The ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. The new standard also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity's nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The pronouncement is to be applied retrospectively and is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted as of January 1, 2017. We have not completed an evaluation of the impact the pronouncement will have on our consolidated financial statements and related disclosures. In April 2015, the FASB issued ASU No. 2015-3, Simplifying the Presentation of Debt Issuance Costs . The ASU 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, consistent with debt discounts. The pronouncement is effective for annual reporting periods beginning after December 15, 2015. We currently report debt issuance costs consistent with the guidance of this ASU; therefore there will be no impact on our consolidated financial statements and related disclosures upon adoption. In April 2015, the FASB issued ASU No. 2015-5, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement . The ASU provides guidance to customers about whether a cloud computing arrangement includes a software license and the related accounting treatment. The pronouncement is effective for annual reporting periods beginning after December 15, 2015. Adoption of this pronouncement is not expected to have a material impact on our consolidated financial statements or related disclosures. In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory , which requires inventory measured using the FIFO or average cost methods to be subsequently measured at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Currently, inventory measured using these methods is required to be subsequently measured at the lower of cost or market with market defined as replacement cost, net realizable value or net realizable value less a normal profit margin. This pronouncement is effective for annual reporting periods beginning after December 15, 2016 on a prospective basis. Early adoption is permitted. We have not completed an evaluation of the impact the pronouncement will have on our consolidated financial statements and related disclosures. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes , which amends existing guidance on income taxes to require the classification of all deferred tax assets and liabilities as noncurrent on the balance sheet. The pronouncement is effective for annual reporting periods beginning after December 15, 2016, and may be applied either prospectively or retrospectively. We have not completed an evaluation of the impact the pronouncement will have on our consolidated financial statements and related disclosures.

Weighted average assumptions used in the option pricing model for options granted	The fair value of each stock option granted is estimated using the Black-Scholes option pricing model. The following table presents the weighted average assumptions used in the option pricing model for options granted. The expected life of the options represents the period of time the options are expected to be outstanding. The expected life is based on our historical exercise trends and post-vest termination data incorporated into a forward-looking stock price model. The expected volatility is based on our implied volatility, which is the volatility forecast that is implied by the prices of actively traded options to purchase our stock observed in the market. The risk-free interest rate is based on the observed U.S. Treasury yield curve in effect at the time the options were granted. The dividend yield is based on our history of dividend payouts. 2014 2013 Expected life (years) 4.6 5.2 Risk-free interest rate 1.5 % 1.3 % Volatility 31.9 % 36.0 % Dividend yield 1.0 % 1.3 % Weighted average fair value per share at grant date $ 16.81 $ 13.79
