EMPLOYEE BENEFIT PLANS

NOTE 7. EMPLOYEE BENEFIT PLANS

We have both funded and unfunded noncontributory defined benefit pension plans covering certain employees primarily in the U.S., the U.K., Germany and Canada. We also provide certain postretirement health care benefits (“other postretirement benefits”), through an unfunded plan, to substantially all U.S. employees who retire and have met certain age and service requirements.

The components of net periodic cost are as follows for the three months ended March 31:


	U.S. Pension Plans						Non-U.S. Pension Plans						Other Postretirement Benefits
	2012			2011			2012			2011			2012			2011

Service cost	$	16		$	9		$	2		$	2		$	3		$	2
Interest cost		5			5			8			8			2			2
Expected return on plan assets		(9	)		(8	)		(9	)		(8	)		—			—
Amortization of prior service cost (benefit)		—			—			—			—			(1	)		(1)
Amortization of net loss		4			2			1			1			1			—
Benefit settlement		—			—			6			—			—			—

Net periodic cost	$	16		$	8		$	8		$	3		$	5		$	3

We invest the assets of our U.S. and Non-U.S. pension plans in investments according to the policies developed by our investment committees. The majority of these assets are in investments whose fair values are determined using Level 2 observable inputs. The changes in the fair value of pension plan assets that were determined by using Level 3 unobservable inputs for the three months ended March 31, 2012 were as follows:


	U.S. Property Fund		U.S. Hedge Funds		Non-U.S. Property Fund		Non-U.S. Insurance Contracts		Total

Ending balance at December 31, 2011	$	5	$	110	$	19	$	15	$	149

Summary of Significant Accounting Policies (Policies)	3 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2012
Summary of Significant 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 to the downstream refining and process and pipeline industries.
Basis of Presentation	Basis of Presentation Our unaudited consolidated condensed financial statements included herein have been prepared in accordance with generally accepted accounting principles in the United States of America and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, certain information and disclosures normally included in our annual financial statements have been condensed or omitted. These unaudited consolidated condensed financial statements should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2011 (“2011 Annual Report”). We believe the unaudited consolidated condensed financial statements included herein reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the interim periods. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the full year. In the notes to the unaudited consolidated condensed financial statements, all dollar and share amounts in tabulations are in millions of dollars and shares, respectively, unless otherwise indicated.
New Accounting Standards Updates	New Accounting Standards Updates In June 2011, the Financial Accounting Standards Board (“FASB”) issued an update to Accounting Standards Codification (“ASC”) 220, Comprehensive Income. This Accounting Standards Update (“ASU”) requires entities to present components of comprehensive income in either a continuous statement of comprehensive income or two separate but consecutive statements that would include reclassification adjustments by component for items that are reclassified from other comprehensive income to net income on the face of the financial statements. In December 2011, the FASB issued an update to this ASU indefinitely deferring the implementation of the reclassification adjustments by component requirement of the ASU issued in June 2011. We adopted the new presentation requirement in the first quarter of 2012. We elected the two-statement approach presenting other comprehensive income in a separate statement immediately following the unaudited consolidated condensed statement of income. In September 2011, the FASB issued an update to ASC 350, Intangibles - Goodwill and Other. This ASU amends the guidance in ASC 350-20 on testing for goodwill impairment. The revised guidance allows entities testing for goodwill impairment to have the option of performing a qualitative assessment before calculating the fair value of the reporting unit. The ASU does not change how goodwill is calculated or assigned to reporting units, nor does it revise the requirement to test annually for impairment. The ASU is limited to goodwill and does not amend the annual requirement for testing other indefinite-lived intangible assets for impairment. The ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We will adopt this ASU for our 2012 goodwill impairment testing and are evaluating the options provided in the ASU.

NOTE 5. FINANCIAL INSTRUMENTS

Fair Value of Financial Instruments

Our financial instruments include cash and cash equivalents, accounts receivable, accounts payable, debt and foreign currency forward contracts. Except as described below, the estimated fair value of such financial instruments at March 31, 2012 and December 31, 2011 approximates their carrying value as reflected in our unaudited consolidated condensed balance sheet.

Debt

The estimated fair value of total debt at March 31, 2012 and December 31, 2011 was $5,264 million and $4,910 million, respectively, which differs from the carrying amounts of $4,518 million and $4,069 million, respectively, included in our unaudited consolidated condensed balance sheet. The fair value was determined using Level 2 inputs including quoted period end market prices.

Segment Information [Abstract]

SEGMENT INFORMATION

NOTE 6. SEGMENT INFORMATION

We conduct our business primarily through operating segments that are aligned with our geographic regions, which have been aggregated into five reportable segments. We aggregate our operating segments within each reportable segment because they have similar economic characteristics and because the long-term financial performance of the segments is affected by similar economic conditions. 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 segments.

Prior to 2012, our reservoir development services business (“RDS”), consisting of consulting services provided to third parties and internal support to our oilfield operations, was included within the Industrial Services segment. Beginning in the first quarter of 2012, we changed our reporting structure to include the RDS business within our four oilfield geographic segments. All prior period segment disclosures for revenue and profit before tax have been reclassified to reflect this new presentation. The impact of this change to the Industrial Services segment was to reduce revenue and increase profit before tax of $23 million and $9 million, respectively, for the three months ended March 31, 2011. There were no material changes in segment assets as a result of this change.

Summarized financial information is shown in the following table.


	Three Months Ended March 31, 2012					Three Months Ended March 31, 2011

Commitments and Contingencies [Abstract]

COMMITMENTS AND CONTINGENCIES

NOTE 8. COMMITMENTS AND CONTINGENCIES

LITIGATION

We are involved in litigation or proceedings that have arisen in our ordinary business activities. We insure against these risks 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 and future legal proceedings. Many of these 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 accruals for losses are calculated by estimating losses for claims using historical claim data, specific loss development factors and other information as necessary.

OTHER

In the normal course of business with customers, vendors and others, we have entered into off-balance sheet arrangements, including surety bonds for performance, letters of credit and other bank guarantees, which totaled approximately $1.2 billion at March 31, 2012. 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 unaudited consolidated condensed financial statements.

- Definition

The entire disclosure for commitments and contingencies.

Summary of Significant Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NOTE 1. 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 to the downstream refining and process and pipeline industries.

Basis of Presentation

Our unaudited consolidated condensed financial statements included herein have been prepared in accordance with generally accepted accounting principles in the United States of America and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, certain information and disclosures normally included in our annual financial statements have been condensed or omitted. These unaudited consolidated condensed financial statements should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2011 (“2011 Annual Report”). We believe the unaudited consolidated condensed financial statements included herein reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the interim periods. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the full year. In the notes to the unaudited consolidated condensed financial statements, all dollar and share amounts in tabulations are in millions of dollars and shares, respectively, unless otherwise indicated.

New Accounting Standards Updates

In June 2011, the Financial Accounting Standards Board (“FASB”) issued an update to Accounting Standards Codification (“ASC”) 220, Comprehensive Income. This Accounting Standards Update (“ASU”) requires entities to present components of comprehensive income in either a continuous statement of comprehensive income or two separate but consecutive statements that would include reclassification adjustments by component for items that are reclassified from other comprehensive income to net income on the face of the financial statements. In December 2011, the FASB issued an update to this ASU indefinitely deferring the implementation of the reclassification adjustments by component requirement of the ASU issued in June 2011. We adopted the new presentation requirement in the first quarter of 2012. We elected the two-statement approach presenting other comprehensive income in a separate statement immediately following the unaudited consolidated condensed statement of income.

In September 2011, the FASB issued an update to ASC 350, Intangibles - Goodwill and Other. This ASU amends the guidance in ASC 350-20 on testing for goodwill impairment. The revised guidance allows entities testing for goodwill impairment to have the option of performing a qualitative assessment before calculating the fair value of the reporting unit. The ASU does not change how goodwill is calculated or assigned to reporting units, nor does it revise the requirement to test annually for impairment. The ASU is limited to goodwill and does not amend the annual requirement for testing other indefinite-lived intangible assets for impairment. The ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We will adopt this ASU for our 2012 goodwill impairment testing and are evaluating the options provided in the ASU.
