Significant Accounting Policies - (Notes)	12 Months Ended

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 for drilling, formation evaluation, completion and production, pressure pumping, and reservoir development 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 and actuarial assumptions to determine costs and liabilities related to employee benefit plans; stock-based compensation and 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. Our products are produced in a standard manufacturing operation, even if produced to our customers' specifications. 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 $430 million, $370 million and $337 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Cash, Cash Equivalents and Short-term Investments
	Cash equivalents include only those investments with an original maturity of three months or less. Short-term investments have an original maturity of greater than three months but less than one year. 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 historical experience, current aging status of the customer accounts, the payment history and financial condition of our customers and the economic environment. Provisions for doubtful accounts are recorded 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 $102 million, $75 million and $100 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Concentration of Credit Risk
	We grant credit to our customers, which operate primarily in the oil and natural gas industry. Although this concentration could affect our overall exposure to credit risk, we believe that our risk is minimized due to the large number of customers we have many of which are geographically diverse, thus spreading the credit risk. To manage this risk, we perform periodic credit evaluations of our customers’ financial condition, including monitoring our customers’ payment history and current credit worthiness. 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 2014, 2013 and 2012, 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 first-in, first-out (“FIFO”) method or the average cost method, which approximates FIFO, 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 circumstances indicate 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. 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, then we would 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 2014, we performed a qualitative assessment for our annual goodwill impairment test. In 2013 and 2012, 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.
	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 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 early 2014, the Venezuelan government established two new exchange mechanisms, SICAD 1 and SICAD 2, where participation in the auction process of each mechanism is controlled by the Venezuelan government depending on the economic sector within which a company operates. These mechanisms are in addition to the existing official exchange rate. We have not been eligible to apply for exchange at the official rate nor have we been allowed to participate in the SICAD 1 auctions. We have successfully participated in SICAD 2 auctions. As a result, during the second quarter of 2014, we adopted the SICAD 2 exchange rate of approximately 50 Bolivars Fuertes ("BsF") per USD for purposes of remeasuring BsF denominated assets and liabilities and revenue and expenses. Prior to this change, we were using the official exchange rate of 6.3 BsF per USD. The impact of this devaluation in the currency was a loss of $12 million resulting from an adjustment of our BsF denominated monetary assets and liabilities. This loss was recorded in MG&A expenses in the second quarter of 2014.
	In early 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 in the first quarter of 2013.
	Financial Instruments
	Our financial instruments include cash and cash equivalents, accounts receivable, 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, 2014 and 2013 approximates their carrying value as reflected in our consolidated balance sheets. For further information on the fair value of our debt, see Note 11. "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 as the facts dictate. 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 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.
	We had outstanding foreign currency forward contracts with notional amounts aggregating $580 million and $486 million to hedge exposure to currency fluctuations in various foreign currencies at December 31, 2014 and 2013, respectively. Based on quoted market prices as of December 31, 2014 or 2013 for forward contracts with similar terms and maturity dates, we recorded a loss of $11 million and a gain of $2 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 effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and is to be applied retrospectively, with early application not permitted. We are currently evaluating the impact the pronouncement will have on our consolidated financial statements and related disclosures.
	In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements and Property, Plant, and Equipment - Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which amends the definition of a discontinued operation by raising the threshold for a disposal to qualify as discontinued operations. The ASU will also require entities to provide additional disclosures about discontinued operations as well as disposal transactions that do not meet the discontinued operations criteria. The pronouncement is effective prospectively for all disposals (except disposals classified as held for sale before the adoption date) or components initially classified as held for sale in periods beginning on or after December 15, 2014. Early adoption is permitted. We adopted the ASU in the second quarter of 2014 and it did not impact our consolidated financial statements or the notes to our financial statements.

	The obligation of the parties to consummate the Merger is subject to customary closing conditions, including, among others, (i) the approval by Baker Hughes’ stockholders of the Merger Agreement; (ii) the approval by Halliburton’s stockholders of the issuance of Halliburton common stock to be issued in the Merger (the “Stock Issuance”); (iii) applicable regulatory approvals, including the termination or expiration of the applicable waiting period under the U.S. Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended; (iv) the absence of legal restraints and prohibitions; and (v) 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.
	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 the quarter. Under the Merger Agreement, we have agreed not to increase the quarterly dividend while the Merger is pending.
	The Merger Agreement contains certain termination rights for each of Baker Hughes and Halliburton. If the Merger Agreement is terminated by (i) Halliburton as a result of a change in the recommendation of Baker Hughes’ board of directors that Baker Hughes’ stockholders approve the Merger Agreement or (ii) Baker Hughes in order to enter into a definitive agreement with a third party for certain alternative transactions, then in either case Baker Hughes would be required to pay Halliburton a termination fee of $1 billion. If the Merger Agreement is terminated because Baker Hughes’ stockholders have not approved the Merger Agreement upon a vote taken thereon and prior to the Baker Hughes stockholder meeting a proposal for an alternative transaction was publicly announced and not withdrawn, then Baker Hughes would be required to pay Halliburton the $1 billion termination fee if, but only if, Baker Hughes enters into an agreement with respect to, or consummates, an alternative transaction with a third party within 12 months of such termination. Baker Hughes will also reimburse Halliburton for certain expenses (up to $40 million) if the Merger Agreement is terminated because Baker Hughes’ stockholders have not approved the Merger Agreement upon a vote taken thereon and prior to the Baker Hughes stockholder meeting a proposal for an alternative transaction was publicly announced and not withdrawn. If, within 12 months after such termination, Baker Hughes enters into an agreement providing for, or consummates, an alternative transaction with a third party, thereby triggering the $1 billion termination fee described above, that termination fee will be reduced by the amount of any expenses previously reimbursed.
	If the Merger Agreement is terminated by (i) Baker Hughes as a result of a change in the recommendation of Halliburton’s board of directors that Halliburton’s stockholders approve the Stock Issuance, (ii) Halliburton in order to enter into a definitive agreement with a third party for certain alternative transactions, or (iii) by either party because Halliburton’s stockholders have not approved the Merger Agreement upon a vote taken thereon, then in each case Halliburton would be required to pay Baker Hughes a termination fee of $1.5 billion. 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 if all 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 and Halliburton expect the Merger to be completed during the second half of 2015. However, 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 incurred costs of $11 million related to the merger which was recorded in MG&A expenses during the fourth quarter of 2014.
	ACQUISITIONS AND DECONSOLIDATION
	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.
	During the fourth quarter of 2014, we sold a portion of our ownership interest in a jointly owned legal entity, and as a result, we no longer have a controlling financial interest. Accordingly, we deconsolidated this joint venture which resulted in a net gain of $34 million. The net gain is primarily the result of the carrying amount of the noncontrolling interest in equity exceeding the carrying amount of the net assets, and was included in MG&A expenses in the statement of operations.

Segment Reporting [Abstract]
Segment information	SEGMENT INFORMATION
	We are a supplier of oilfield services, products, technology and systems to the worldwide oil and natural gas business, referred to as oilfield operations, which are managed through operating segments that are aligned with our geographic regions. We also provide services and products to the downstream chemicals, and process and pipeline services, referred to as Industrial Services.
	During 2014, certain North African entities previously reported in our Middle East/Asia Pacific segment were realigned and are now reported within our Europe/Africa/Russia Caspian segment to reflect how we manage the business. Accordingly, all prior segment disclosures have been recast to reflect this realignment.
	The performance of our operating segments is evaluated based on profit before tax, which is defined as income before income taxes and before the following: net interest expense, corporate expenses, and certain gains and losses not allocated to the operating segments.

Stock-based Compensation - (Notes)	12 Months Ended
	Dec. 31, 2014
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:
		2014				2013				2012
	Stock-based compensation cost	$	122			$	115			$	115
	Tax benefit	(26		)		(24		)		(20		)
	Stock-based compensation cost, net of tax	$	96			$	91			$	95
	For our stock options and restricted stock awards and units, we currently have 60.7 million authorized for issuance and as of December 31, 2014, approximately 25.7 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.
	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				2012
	Expected life (years)	4.6				5.2				5.4
	Risk-free interest rate	1.5		%		1.3		%		0.9		%
	Volatility	31.9		%		36		%		41.4		%
	Dividend yield	1		%		1.3		%		1.4		%
	Weighted average fair value per share at grant date	$	16.81			$	13.79			$	14.51
	The following table presents the changes in stock options outstanding and related information (in thousands, except per option prices):
		Number of					Weighted Average
		Options					Exercise Price
							Per Option
	Outstanding at December 31, 2013		12,206					$	50.57
	Granted		1,089					63.67
	Exercised		(3,158	)				44.06
	Forfeited		(231	)				51.71
	Expired		(169	)				69.1
	Outstanding at December 31, 2014		9,737					$	53.8
	Exercisable at December 31, 2014		6,719					$	54.8
	The weighted average remaining contractual term for options outstanding and options exercisable at December 31, 2014 were 5.7 years and 4.5 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 2014, 2013 and 2012 was $70 million, $11 million and $3 million, respectively. The income tax benefit realized from stock options exercised was $19.6 million, $2.0 million and $0.8 million in 2014, 2013 and 2012, respectively.
	The total fair value of options vested in 2014, 2013 and 2012 was $29 million, $31 million and $28 million, respectively. As of December 31, 2014, there was $15 million of total unrecognized compensation cost related to unvested stock options, which is expected to be recognized over a weighted average period of two years.
	The total intrinsic value of stock options outstanding at December 31, 2014 was $74 million, of which $53 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 $56.07 of our common stock as of the end of 2014 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			Weighted Average
		Awards and Units			Grant Date Fair
					Value Per Award/Unit
	Unvested balance at December 31, 2013	2,652			$	47.44
	Granted	1,498			69.67
	Vested	(1,206	)		49.79
	Forfeited	(212	)		56.63
	Unvested balance at December 31, 2014	2,732			$	57.88
	The weighted average grant date fair value per share for RSAs and RSUs granted in 2014, 2013 and 2012 was $69.67, $45.58 and $47.10, respectively. The total fair value of RSAs and RSUs vested in 2014, 2013 and 2012 was $60 million, $58 million and $55 million, respectively. As of December 31, 2014, there was $90 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, 2014, there were 6 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:
		2014				2013				2012
	Expected life (years)	0.5				0.5				0.5
	Risk-free interest rate	0.03		%		0.1		%		0.1		%
	Volatility	24.7		%		30.3		%		44.1		%
	Dividend yield	1		%		1.4		%		1.3		%

	Income before income taxes	$	2,627			$	1,715			$	1,982
	The provision for income taxes differs from the amount computed by applying the U.S. statutory income tax rate to income before income taxes for the reasons set forth below for the years ended December 31:
		2014			2013			2012
	U.S. statutory income tax rate	35	%		35	%		35	%

	Other - net	(1.7	)		(0.2	)		0.8
	Total effective tax rate	34.1	%		35.7	%		33.6	%
	During the fourth quarter of 2013, we recognized a net tax benefit of $18 million as a result of the reorganization of certain of our foreign subsidiaries. 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:
		2014				2013
	Deferred tax assets:
	Receivables	$	65			$	68
	Inventory	376				347
	Employee benefits	106				98
	Other accrued expenses	173				185
	Operating loss carryforwards	493				403
	Tax credit carryforwards	481				462
	Other	104				70
	Subtotal	1,798				1,633
	Valuation allowances	(1,051		)		(949		)
	Total	747				684
	Deferred tax liabilities:
	Goodwill and other intangibles	334				356
	Property	459				459
	Undistributed earnings of foreign subsidiaries	26				14
	Other	16				24
	Total	835				853
	Net deferred tax liability	$	(88	)		$	(169	)
	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, 2014, valuation allowances totaled $1,051 million consisting of $465 million for operating loss carryforwards, $471 million for foreign tax credit carryforwards, and $115 million for other deferred tax assets in various jurisdictions. There are $28 million of operating loss carryforwards without a valuation allowance, the majority of which 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, 2014, the cumulative amount of earnings upon which the U.S. income taxes have not been provided is approximately $6.1 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, 2014, we had approximately $134 million of foreign tax credits which may be carried forward indefinitely under applicable foreign law, and $347 million of foreign tax credits which expire in 2015 through 2024 under U.S. tax law.
	At December 31, 2014, we had $291 million of tax liabilities for total gross unrecognized tax benefits related to uncertain tax positions, which includes liabilities for interest and penalties of $36 million and $13 million, respectively. If we were to prevail on all uncertain tax positions, the net effect would be a decrease to our income tax provision of approximately $273 million. The remaining approximately $18 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.

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, 2014, we had approximately $110 million of tax liabilities, net of $7 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, 2014, approximately $174 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. These jurisdictions are those we project to have the highest tax liability for 2015.

The fair value was determined using quoted period end market prices.
	At December 31, 2014, 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, 2014, we were in compliance with all of the credit facility's covenants, and there were no direct borrowings under the credit facility during 2014. 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, 2014, we had no borrowings outstanding under the commercial paper program. Maturities of debt at December 31, 2014 are as follows: 2015 - $220 million; 2016 - $27 million; 2017 - $20 million; 2018 - $1,026 million; 2019 - $22 million; and $2,818 million thereafter.
	The weighted average interest rate on short-term borrowings outstanding at December 31, 2014 and 2013 were 10.0% and 4.3%, respectively.

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.
	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 funded status position represents the difference between the benefit obligation and the plan assets. 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:

	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

	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 2015 are $15 million and $0.4 million, respectively. The estimated net actuarial loss and 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 2015 are $2 million and $12 million, respectively.

In selecting the expected rate of return on plan assets, we consider the average rate of earnings expected on the funds invested or to be invested to provide for the benefits of these plans. This includes considering the trusts’ asset allocation and the expected returns likely to be earned over the life of the plans.

Assumed health care cost trend rates have a significant effect on the amounts reported for other postretirement benefits. As of December 31, 2014, 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 2014:
	One Percentage				One Percentage
	Point Increase				Point Decrease
Effect on total of service and interest cost components	$	0.2			$	(0.2	)
Effect on postretirement welfare benefit obligation	$	1.1			$	(1.5	)
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 fair value of the assets in our U.S. Pension Plan at December 31, 2014 and 2013, by asset category, are presented below and were determined based on valuation techniques categorized as follows:
•	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.

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.
The table below presents the fair value of the assets in our Non-U.S. Plans by asset category and by valuation technique at December 31:

Expected Cash Flows
For all pension plans, we make annual contributions to the plans in amounts equal to or greater than amounts necessary to meet minimum governmental funding requirements. In 2015, we expect to contribute between $75 million and $85 million to our funded and unfunded pension plans. In 2015, we also expect to make benefit payments related to other postretirement benefits of between $10 million and $15 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.

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 $263 million, $240 million and $232 million in 2014, 2013 and 2012, 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 $17 million, $15 million and $17 million in 2014, 2013 and 2012, respectively. In 2015, we estimate we will contribute between $265 million and $290 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, 2014 and 2013 was $30 million and $23 million, respectively, and is included in other liabilities in our consolidated balance sheets.

	LEASES
	At December 31, 2014, 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, 2019 are $284 million, $187 million, $118 million, $64 million and $39 million, respectively, and $114 million in the aggregate thereafter. Rent expense was $747 million, $702 million and $559 million for the years ended December 31, 2014, 2013 and 2012, respectively. We have not entered into any significant capital leases during the three years ended December 31, 2014.
	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, and
	•	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. 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 November 26, 2014, a seventh class action challenging the merger was filed by a purported Company shareholder 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, 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.  The Defendants are currently scheduled to respond to the complaint on February 13, 2015.
	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 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 now 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. No timetable for the conduct of the arbitration has yet been established.
	During 2014, we investigated customer notifications related to a possible equipment failure in a natural gas storage system in the Europe/Africa/Russia Caspian region, 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. At this time, we are not able to predict whether our products will need to be repaired or replaced and are not able to reasonably estimate the impact, if any, such repairs or replacements or other damages would have on our financial position, results of operations or cash flows.
	We are a defendant in various labor claims including the following matters. On April 28, 2014, a collective action lawsuit alleging that we failed to pay class of workers overtime in compliance with the Fair Labor Standards Act ("FLSA") was filed titled Michael Ciamillo, individually, etc., et al. vs. Baker Hughes Incorporated in the U.S. District Court for the District of Alaska (“Ciamillo”). During the fourth quarter of 2014, the parties agreed to settle the Ciamillo lawsuit, including certain state law claims, for $5 million, subject to final court approval. On December 10, 2013, a class and collective action lawsuit alleging that we failed to pay a nationwide class of workers overtime in compliance with the FLSA and certain state laws was filed titled Lea et al. v. Baker Hughes, Inc. in the U.S. District Court for the Southern District of Texas, Galveston Division ("Lea"). During the second quarter of 2014, the parties agreed to settle the Lea lawsuit, subject to final court approval, and we recorded a charge of $62 million, which includes the Lea settlement amount and associated costs and an amount for settlement of another wage and hour lawsuit. On October 21, 2013, a collective action lawsuit alleging that we failed to pay a class of workers overtime in compliance with the FLSA was filed titled Zamora et al. v. Baker Hughes Incorporated in the U.S. District Court for the Southern District of Texas, Corpus Christi Division (“Zamora”). In October of 2014, the parties agreed to settle the Zamora lawsuit for an amount that was not material to 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.
	We were among several unrelated companies who received a subpoena from the Office of the New York Attorney General, dated June 17, 2011. The subpoena we received sought information and documents relating to, among other things, natural gas development and hydraulic fracturing, and we have responded.
	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 some of our present and former manufacturing locations or other facilities, the majority of which relate to properties no longer actively used in operations. 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 $34 million, which includes accruals of $3 million and $4 million for the various Superfund sites, at December 31, 2014 and 2013, 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 $1.3 billion at December 31, 2014. 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, 2019 of $532 million, $312 million, $256 million, $156 million and $72 million, respectively, and $99 million in the aggregate thereafter.

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 for drilling, formation evaluation, completion and production, pressure pumping, and reservoir development 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 and actuarial assumptions to determine costs and liabilities related to employee benefit plans; stock-based compensation and 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. Our products are produced in a standard manufacturing operation, even if produced to our customers' specifications. 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 $430 million, $370 million and $337 million for the years ended December 31, 2014, 2013 and 2012, respectively.
Cash, Cash Equivalents and Short-term Investments	Cash, Cash Equivalents and Short-term Investments
	Cash equivalents include only those investments with an original maturity of three months or less. Short-term investments have an original maturity of greater than three months but less than one year. 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 historical experience, current aging status of the customer accounts, the payment history and financial condition of our customers and the economic environment. Provisions for doubtful accounts are recorded 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 $102 million, $75 million and $100 million for the years ended December 31, 2014, 2013 and 2012, respectively.
Concentration Risk, Credit Risk	Concentration of Credit Risk
	We grant credit to our customers, which operate primarily in the oil and natural gas industry. Although this concentration could affect our overall exposure to credit risk, we believe that our risk is minimized due to the large number of customers we have many of which are geographically diverse, thus spreading the credit risk. To manage this risk, we perform periodic credit evaluations of our customers’ financial condition, including monitoring our customers’ payment history and current credit worthiness. 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 2014, 2013 and 2012, 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 first-in, first-out (“FIFO”) method or the average cost method, which approximates FIFO, 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 circumstances indicate 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. 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, then we would 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 2014, we performed a qualitative assessment for our annual goodwill impairment test. In 2013 and 2012, 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.
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 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 early 2014, the Venezuelan government established two new exchange mechanisms, SICAD 1 and SICAD 2, where participation in the auction process of each mechanism is controlled by the Venezuelan government depending on the economic sector within which a company operates. These mechanisms are in addition to the existing official exchange rate. We have not been eligible to apply for exchange at the official rate nor have we been allowed to participate in the SICAD 1 auctions. We have successfully participated in SICAD 2 auctions. As a result, during the second quarter of 2014, we adopted the SICAD 2 exchange rate of approximately 50 Bolivars Fuertes ("BsF") per USD for purposes of remeasuring BsF denominated assets and liabilities and revenue and expenses. Prior to this change, we were using the official exchange rate of 6.3 BsF per USD. The impact of this devaluation in the currency was a loss of $12 million resulting from an adjustment of our BsF denominated monetary assets and liabilities. This loss was recorded in MG&A expenses in the second quarter of 2014.
	In early 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 in the first quarter of 2013.
Financial Instruments	Financial Instruments
	Our financial instruments include cash and cash equivalents, accounts receivable, 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, 2014 and 2013 approximates their carrying value as reflected in our consolidated balance sheets. For further information on the fair value of our debt, see Note 11. "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 as the facts dictate. 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 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.
	We had outstanding foreign currency forward contracts with notional amounts aggregating $580 million and $486 million to hedge exposure to currency fluctuations in various foreign currencies at December 31, 2014 and 2013, respectively. Based on quoted market prices as of December 31, 2014 or 2013 for forward contracts with similar terms and maturity dates, we recorded a loss of $11 million and a gain of $2 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 effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and is to be applied retrospectively, with early application not permitted. We are currently evaluating the impact the pronouncement will have on our consolidated financial statements and related disclosures.
	In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements and Property, Plant, and Equipment - Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which amends the definition of a discontinued operation by raising the threshold for a disposal to qualify as discontinued operations. The ASU will also require entities to provide additional disclosures about discontinued operations as well as disposal transactions that do not meet the discontinued operations criteria. The pronouncement is effective prospectively for all disposals (except disposals classified as held for sale before the adoption date) or components initially classified as held for sale in periods beginning on or after December 15, 2014. Early adoption is permitted. We adopted the ASU in the second quarter of 2014 and it did not impact our consolidated financial statements or the notes to our financial statements.

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.
