MARATHON OIL CORPORATION

Notes to Consolidated Financial Statements (Unaudited)

1.    Basis of Presentation

These consolidated financial statements are unaudited; however, in the opinion of management, these statements reflect all adjustments necessary for a fair statement of the results for the periods reported.  All such adjustments are of a normal recurring nature unless disclosed otherwise.  These consolidated financial statements, including notes, have been prepared in accordance with the applicable rules of the Securities and Exchange Commission ("SEC") and do not include all of the information and disclosures required by accounting principles generally accepted in the United States of America ("U.S. GAAP") for complete financial statements.

As the result of the sale of our Angola assets in the first quarter of 2014 and the sale our Norway business, which closed October 15, 2014 (see Note 6), these businesses are reflected as discontinued operations in all periods presented. The disclosures in this report related to results of operations and cash flows are presented on the basis of continuing operations, unless otherwise noted. Assets and liabilities are presented as held for sale in the consolidated balance sheets as of December 31, 2013 for our Angola business and September 30, 2014 for our Norway business.

These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Marathon Oil Corporation 2013 Annual Report on Form 10-K.  The results of operations for the third quarter and first nine months of2014 are not necessarily indicative of the results to be expected for the full year.

2.   Accounting Standards

Not Yet Adopted

In August 2014, the Financial Accounting Standards Board ("FASB") issued an update that requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in United States ("U.S.") auditing standards.  This standard is effective for us in the first quarter of 2017 and early adoption is permitted. We do not expect the adoption of this standard to have a significant impact on our consolidated results of operations, financial position or cash flows.

In May 2014, the FASB issued an update that supersedes the existing revenue recognition requirements. This standard includes a five-step revenue recognition model to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. Among other things, the standard also eliminates industry-specific revenue guidance, requires enhanced disclosures about revenue, provides guidance for transactions that were not previously addressed comprehensively, and improves guidance for multiple-element arrangements. This standard is effective for us in the first quarter of 2017 and should be applied retrospectively to each prior reporting period presented or with the cumulative effect of initially applying the update recognized at the date of initial application. Early adoption is not permitted. We are evaluating the provisions of this accounting standards update and assessing the impact, if any, it may have on our consolidated results of operations, financial position or cash flows.

In April 2014, the FASB issued an amendment to accounting standards that changes the criteria for reporting discontinued operations while enhancing related disclosures. Under the amendment, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization’s operations and financial results. Examples include disposal of a major geographic area, a major line of business, or a major equity method investment.  Expanded disclosures about the assets, liabilities, income and expenses of discontinued operations will be required.  In addition, disclosure of the pretax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting will be made in order to provide users with information about the ongoing trends in an organization’s results from continuing operations.  The amendments are effective for us in the first quarter of 2015 and early adoption is permitted. We did not elect early adoption of this amendment and do not expect its future adoption to have a significant impact on our consolidated results of operations, financial position or cash flows.

Recently Adopted

In June 2013, the FASB ratified the Emerging Issues Task Force consensus which requires that an unrecognized tax benefit (or a portion thereof) be presented as a reduction to a deferred tax asset for an available net operating loss carryforward, a similar tax loss or tax credit carryforward. This accounting standards update was effective for us beginning in the first quarter of 2014 and is required to be applied prospectively. Adoption of this standard did not have a significant impact on our consolidated results of operations, financial position or cash flows.

MARATHON OIL CORPORATION

Notes to Consolidated Financial Statements (Unaudited)

In February 2013, an accounting standards update was issued to provide guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, except for obligations such as asset retirement and environmental obligations, contingencies, guarantees, income taxes and retirement benefits, which are separately addressed within U.S. GAAP. This accounting standards update was effective for us beginning in the first quarter of 2014 and is required to be applied retrospectively. Adoption of this standard did not have a significant impact on our consolidated results of operations, financial position or cash flows.

3.   Variable Interest Entity

The owners of the Athabasca Oil Sands Project, in which we hold a 20 percent undivided interest, contracted with a wholly owned subsidiary of a publicly traded Canadian limited partnership (“Corridor Pipeline”) to provide materials transportation capabilities among the Muskeg River and Jackpine mines, the Scotford upgrader and markets in Edmonton.  Costs under this contract are accrued and recorded on a monthly basis, with current liabilities of $3 million recorded at September 30, 2014, consistent with December 31, 2013.  This contract qualifies as a variable interest contractual arrangement, and the Corridor Pipeline qualifies as a variable interest entity (“VIE”).  We hold a variable interest but are not the primary beneficiary because our shipments are only 20 percent of the total; therefore, the Corridor Pipeline is not consolidated by us.  Our maximum exposure to loss as a result of our involvement with this VIE is the amount we expect to pay over the contract term, which was $586 million as of September 30, 2014.  The liability on our books related to this contract at any given time will reflect amounts due for the immediately previous month’s activity, which is substantially less than the maximum exposure over the contract term.

4.    Income per Common Share

Basic income per share is based on the weighted average number of common shares outstanding.  Diluted income per share assumes exercise of stock options, provided the effect is not antidilutive. The per share calculations below exclude 2 million and 4 million stock options for the third quarters of 2014 and 2013 and 4 million and 5 million stock options for the first nine months of2014 and 2013 as they were antidilutive.

5. Acquisitions

2014 - North America Exploration and Production ("E&P") Segment

In an asset acquisition that closed August 2014, we added acreage to our Oklahoma resource position at a cost of approximately $80 million before final settlement adjustments.

2013 - North America E&P Segment

In July 2013, we acquired additional acreage in the Eagle Ford in a transaction valued at $97 million, including a carried interest of $23 million which was fully satisfied as of September 30, 2014. The pro forma impact of this transaction is not material to our consolidated statements of income for any periods presented.

The transaction was accounted for as a business combination with the fair values of assets acquired and liabilities assumed measured primarily using an income approach, specifically utilizing a discounted cash flow model. The estimated fair values were based on significant inputs not observable in the market, and therefore represent Level 3 measurements. Significant inputs included estimated reserve volumes, the expected future production profile, estimated commodity prices, assumptions regarding future operating and development costs and a discount rate of approximately 10 percent. The entire up-front cash consideration of $74 million was allocated to property, plant and equipment at the acquisition date.

6. Dispositions

2014 - International E&P Segment

In June 2014, we entered into an agreement to sell our Norway business, including the operated Alvheim floating production, storage and offloading vessel, 10 operated licenses and a number of non-operated licenses on the Norwegian Continental Shelf in the North Sea, with an effective date of January 1, 2014.  The transaction closed on October 15, 2014. After adjustment for debt, net working capital and interest on the net purchase price, we received proceeds of approximately $2.1 billion and expect to record a pretax gain of approximately $1.4 billion in the fourth quarter of 2014.

Our Norway business is reflected as discontinued operations in the consolidated statements of income and the consolidated statements of cash flows for all periods presented. Select amounts reported in discontinued operations were as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
(In millions)	2014		2013		2014			2013
Revenues applicable to discontinued operations	$	528	$	699	$	1,901		$	2,431
Pretax income from discontinued operations	$	487	$	523	$	1,617		$	1,945
After-tax income from discontinued operations	$	127	$	122	$	449	(a)	$	502

^(a)  Includes a tax benefit of $26 million related to a decrease in the valuation allowance on U.S. foreign tax credits from the Norway operations.

Assets and liabilities presented as held for sale in the September 30, 2014 consolidated balance sheet reflect the Norway business.

In the first quarter of 2014, we closed the sales of our non-operated 10 percent working interests in the Production Sharing Contracts and Joint Operating Agreements for Angola Blocks 31 and 32 for aggregate proceeds of approximately $2 billion. Included in the after-tax gain is a deferred tax benefit reflecting our ability to utilize foreign tax credits that otherwise would have needed a valuation allowance.

^(a)  Includes an after-tax gain on disposition of discontinued operations of $576 million.

Assets and liabilities presented as held for sale in the December 31, 2013 consolidated balance sheet reflect the Angola business.

2014 - North America E&P Segment

In June 2014, we closed the sale of non-core acreage located in the far northwest portion of the Williston Basin for proceeds of $90 million. A pretax loss of $91 million was recorded in the second quarter of 2014.

2013 - North America E&P Segment

In June 2013, we closed the sale of our interests in the DJ Basin for proceeds of $19 million. A pretax loss of $114 million was recorded in the second quarter of 2013.

In February 2013, we conveyed our interests in the Marcellus natural gas shale play to the operator. A $43 million pretax loss on this transaction was recorded in the first quarter of 2013.

In February 2013, we closed the sale of our interest in the Neptune gas plant, located onshore Louisiana, for proceeds of $166 million. A $98 million pretax gain on this sale was recorded in the first quarter of 2013.

In January 2013, we closed the sale of our remaining assets in Alaska, for proceeds of $195 million, subject to a six-month escrow of $50 million which was collected in July 2013. After closing adjustments were made in the second quarter of 2013, the pretax gain on this sale was $55 million.

7.    Segment Information

  We have three reportable operating segments.  Each of these segments is organized based upon both geographic location and the nature of the products and services it offers.

• North America E&P ("N.A. E&P") – explores for, produces and markets liquid hydrocarbons and natural gas in North America;

• International E&P ("Int'l E&P") – explores for, produces and markets liquid hydrocarbons and natural gas outside of North America and produces and markets products manufactured from natural gas, such as liquefied natural gas ("LNG")and methanol, in Equatorial Guinea; and

• Oil Sands Mining (“OSM”) – mines, extracts and transports bitumen from oil sands deposits in Alberta, Canada, and upgrades the bitumen to produce and market synthetic crude oil and vacuum gas oil.

Information regarding assets by segment is not presented because it is not reviewed by the chief operating decision maker (“CODM”).  Segment income represents income from continuing operations excluding certain items not allocated to segments, net of income taxes, attributable to the operating segments. Our corporate and operations support general and administrative costs are not allocated to the operating segments. These costs primarily consist of employment costs (including pension effects), professional services, facilities and other costs associated with corporate and operations support activities. Unrealized gains or losses on crude oil derivative instruments, certain impairments, gains or losses on dispositions or other items that affect comparability (as determined by the CODM) also are not allocated to operating segments.

As discussed in Note 5, we sold our Angola assets in the first quarter of 2014 and our Norway business on October 15, 2014. The Angola and Norway businesses are reflected as discontinued operations and are excluded from the International E&P segment in all periods presented.

^(a)     Settlements are recognized as they occur, once it is probable that lump sum payments from a plan for a given year will exceed the plan's total service and interest cost for that year.

During the first nine months of 2014 and 2013, we recorded the effects of partial settlements of our U.S. pension plans and we remeasured the plans’ assets and liabilities as of the applicable balance sheet dates. As a result, we recognized a pretax increase of $10 million and a pretax decrease of $22 million in actuarial losses in other comprehensive income for the third quarter and first nine months of 2014 and a pretax decrease of $24 million and $163 million in actuarial losses in other comprehensive income for the third quarter and first nine months of 2013.

During the first nine months of 2014, we made contributions of $94 million to our funded pension plans.  We expect to make additional contributions up to an estimated $24 million to our funded pension plans over the remainder of 2014.  Current benefit payments related to unfunded pension plans were $83 million, and payments related to other postretirement benefit plans were $11 million during the first nine months of 2014.

9.   Income Taxes

The effective income tax rate is influenced by a variety of factors including the geographic and functional sources of income and the relative magnitude of these sources of income. The difference between the total provision and the sum of the amounts allocated to segments is reported in the “Not Allocated to Segments” column of the tables in Note 7.

Our effective income tax rates on continuing operations for the first nine months of 2014 and 2013 were 32 percent and 63 percent.  The decrease in the effective tax rate on continuing operations in the first nine months of 2014 is primarily due to a decrease in pretax income from Libya operations, where the tax rate is in excess of 90 percent.

The tax provision (benefit) applicable to Libyan ordinary income (loss) was recorded as a discrete item in the first nine months of 2014 and 2013.  Excluding Libya, the effective tax rates on continuing operations would be 32 percent and 36 percent for the first nine months of 2014 and 2013. In Libya, there remains uncertainty around future production and sales levels. Reliable estimates of 2014 and 2013 Libyan annual ordinary income from our operations could not be made and the range of possible

MARATHON OIL CORPORATION

Notes to Consolidated Financial Statements (Unaudited)

scenarios in the worldwide annual effective tax rate calculation demonstrates significant variability.  Thus, for the first nine months of 2014 and 2013, estimated annual effective tax rates were calculated excluding Libya and applied to consolidated ordinary income.

In the second quarter of 2014, we reviewed our foreign operations, including the disposition of Norway, and concluded that our foreign operations do not have the same level of immediate capital needs as previously expected.  Therefore, we no longer intend for previously unremitted foreign earnings of $746 million associated with our United Kingdom ("U.K.") operations to be permanently reinvested outside the U.S.  Foreign tax credits associated with these earnings would be sufficient to offset any incremental U.S. tax liabilities.  The remaining undistributed income of certain consolidated foreign subsidiaries for which no U.S. deferred income tax provision has been recorded because we intend to permanently reinvest such income in our foreign operations amounted to $994 million at September 30, 2014.  If such income were not permanently reinvested, income tax expense of approximately $348 million would be recorded, not including potential utilization of foreign tax credits.

10.   Inventories

 Inventories are carried at the lower of cost or market value.

	September 30,		December 31,
(In millions)	2014		2013
Liquid hydrocarbons, natural gas and bitumen	$	80	$	55
Supplies and other items	299		309
Inventories, at cost	$	379	$	364

11.  Property, Plant and Equipment

International E&P (a)	2,754		3,590
Oil Sands Mining	9,486		9,447
Corporate	120		135
Net property, plant and equipment	$	28,658	$	28,145

^(a)  International E&P decrease is due to Norway assets reflected as held for sale in the September 30, 2014 consolidated balance sheet.

In the third quarter of 2013, our production in Libya was interrupted by third-party labor strikes at the port facilities, which later resulted in a blockade of the Es Sider terminal from which we export oil.  In July 2014, Libya's National Oil Corporation rescinded force majeure associated with these third-party labor strikes at the Es Sider terminal. Our first 2014 lifting occurred in August, and was sourced from existing inventory at the terminal.  Production from the Waha concessions resumed in August 2014; however, considerable uncertainty remains around future production and sales levels.  As of September 30, 2014, our net property, plant and equipment investment in Libya is approximately $771 million. We and our partners in the Waha concessions continue to assess the situation and the condition of our assets in Libya. Our periodic assessment of the carrying value of our net property, plant and equipment in Libya specifically considers the net investment in the assets, the duration of our concessions and the reserves anticipated to be recoverable in future periods.

Exploratory well costs capitalized greater than one year after completion of drilling were $155 million as of September 30, 2014 (including $29 million related to Norway project costs which are reflected in noncurrent assets held for sale) and $281 million as of December 31, 2013 (including $70 million related to Norway project costs). This $126 million net decrease was the result of a $153 million reduction due to the sale of our interests in Angola Blocks 31 and 32 and a decrease of $39 million due to the commencement of drilling at the Boyla development and sanction of the Viper project offshore Norway, partially offset by an increase of $66 million for Diaba License G4-223 offshore Gabon where the Diaman-1B well reached total depth in the third quarter of 2013. We are analyzing new 3D seismic, integrated with existing technical data, in order to finalize the next steps in the exploration program on the Diaba License.

Fair Values - Nonrecurring

The following table shows the values of assets, by major category, measured at fair value on a nonrecurring basis in periods subsequent to their initial recognition.

	Three Months Ended September 30,
	2014				2013
(In millions)	Fair Value		Impairment		Fair Value		Impairment
Long-lived assets held for use	$	43	$	109	$	5	$	11

	Nine Months Ended September 30,
	2014				2013
(In millions)	Fair Value		Impairment		Fair Value		Impairment
Long-lived assets held for use	$	43	$	130	$	5	$	49

All long-lived assets held for use that were impaired in the first nine months of 2014 and 2013 were held by our North America E&P segment. The fair values of each were measured using an income approach based upon internal estimates of future production levels, prices and discount rate, all of which are Level 3 inputs.  Inputs to the fair value measurement included reserve and production estimates made by our reservoir engineers, estimated commodity prices adjusted for quality and location differentials, and forecasted operating expenses for the remaining estimated life of the reservoir.

The Ozona development in the Gulf of Mexico ceased producing in the first quarter of 2013 and a $21 million impairment was recorded. In the first nine months of 2014, we recorded additional impairments of $30 million at Ozona as a result of estimated abandonment cost revisions.

In the third quarter of 2014, impairments of $53 million were recorded to certain other Gulf of Mexico properties, as a result of estimated abandonment cost and other revisions, to an aggregate fair value of $19 million.

Also in the third quarter of 2014, two additional fields were impaired a total of $47 million to an aggregate fair value of $24 million primarily due to lower forecasted commodity prices.

In the first quarter of 2013, as a result of our decision to wind down operations in the Powder River Basin due to poor economics, an impairment of $15 million was recorded.

Other impairments of long-lived assets held for use by our North America E&P segment in the first nine months of 2013 were a result of reduced drilling expectations, reductions of estimated reserves or declining commodity prices.

Crude oil prices began declining in the third quarter of 2014 and continued to decrease in October 2014. A period of sustained low commodity prices could result in additional non-cash impairment charges related to our assets in future periods.

Fair Values – Financial Instruments

Our current assets and liabilities include financial instruments, the most significant of which are receivables, commercial paper and payables. We believe the carrying values of our receivables, commercial paper and payables approximate fair value. Our fair value assessment incorporates a variety of considerations, including (1) the short-term duration of the instruments, (2) our investment-grade credit rating, and (3) our historical incurrence of and expected future insignificance of bad debt expense, which includes an evaluation of counterparty credit risk.

Notes to Consolidated Financial Statements (Unaudited)

The following table summarizes financial instruments, excluding current receivables, commercial paper, current payables, capital leases and derivative financial instruments, and their reported fair value by individual balance sheet line item at September 30, 2014 and December 31, 2013.

	September 30, 2014				December 31, 2013
	Fair		Carrying		Fair		Carrying

Financial assets
Other noncurrent assets	$	194	$	189	$	154	$	147

Financial liabilities
Other current liabilities	13		13		13		13
Long-term debt, including current portion (a)	7,057		6,394		6,922		6,427
Deferred credits and other liabilities	94		150		149		147
Total financial liabilities	$	7,164	$	6,557	$	7,084	$	6,587

^(a)    Excludes capital leases.

Fair values of our financial assets included in other noncurrent assets and of our financial liabilities included in other current liabilities and deferred credits and other liabilities are measured using an income approach. Most inputs are internally generated, which results in a Level 3 classification. Estimated future cash flows are discounted using a rate deemed appropriate to obtain the fair value.

Most of our long-term debt instruments are publicly-traded. A market approach, based upon quotes from major financial institutions, which are Level 2 inputs, is used to measure the fair value of such debt. The fair value of our debt that is not publicly-traded is measured using an income approach. The future debt service payments are discounted using the rate at which we currently expect to borrow. All inputs to this calculation are Level 3.

14. Derivatives

For further information regarding the fair value measurement of derivative instruments, see Note 13. All of our interest rate derivatives are subject to enforceable master netting arrangements or similar agreements under which we may report net amounts. Netting is assessed by counterparty, and as of September 30, 2014 and December 31, 2013, there were no offsetting amounts. Positions by contract were all either assets or liabilities.

The following tables present the gross fair values of derivative instruments, excluding cash collateral, and the reported net amounts along with where they appear on the consolidated balance sheets as of September 30, 2014 and December 31, 2013.

As of September 30, 2014 and December 31, 2013, our foreign currency forwards had an aggregate notional amount of 2,246 million and 2,387 million Norwegian Kroner at weighted average forward rates of 6.149 and 6.060. These forwards hedge the current Norwegian tax liability of the subsidiary that holds our Norway business. Those outstanding at September 30, 2014 have settlement dates through February 2015 and were transfered to the purchaser of our Norway business upon closing of the sale on October 15, 2014.

The pretax effects of derivative instruments designated as hedges of fair value in our consolidated statements of income are summarized in the table below. There is no ineffectiveness related to the fair value hedges.

Stock-based performance unit awards

 During the first nine months of 2014, we granted 221,491 stock-based performance units to certain officers. The grant date fair value per unit was $34.28.

16.    Debt

As of September 30, 2014, we had no borrowings against our revolving credit facility, as described below, or under our U.S. commercial paper program that is backed by the revolving credit facility.

In May 2014, we amended our $2.5 billion unsecured revolving credit facility (the "Credit Facility"), and extended the maturity to May 2019. Terms of this amended Credit Facility include the ability to request two one-year extensions and an option to increase the commitment amount by up to an additional $1.0 billion, subject to the consent of any increasing lenders, and sub-facilities for swing-line loans and letters of credit up to an aggregate amount of $100 million and $500 million.  Fees on the unused commitment of each lender range from 8 basis points to 22.5 basis points depending on our credit ratings. Borrowings under the Credit Facility bear interest, at our option, at either (a) an adjusted LIBOR rate plus a margin ranging from 87.5 basis points to 150 basis points depending on our credit ratings or (b) the Base Rate plus a margin ranging from 0 basis points to 50 basis points depending on our credit ratings.  Base Rate is defined as a per annum rate equal to the greatest of (a) the prime rate, (b) the federal funds rate plus one-half of one percent or (c) LIBOR for a one-month interest period plus 1 percent.

The agreement contains a covenant that requires our ratio of total debt to total capitalization not to exceed 65 percent as of the last day of each fiscal quarter.  If an event of default occurs, the lenders holding more than half of the commitments may terminate the commitments under the Credit Facility and require the immediate repayment of all outstanding borrowings and the cash collateralization of all outstanding letters of credit under the Credit Facility.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

  We are a global energy company based in Houston, Texas, with operations in North America, Europe, Africa and the Middle East.  We have three reportable operating segments. Each of these segments is organized based upon both geographic location and the nature of the products and services it offers.

• North America E&P – explores for, produces and markets liquid hydrocarbons and natural gas in North America;

• International E&P – explores for, produces and markets liquid hydrocarbons and natural gas outside of North America and produces and markets products manufactured from natural gas, such as LNG and methanol, in Equatorial Guinea; and

• Oil Sands Mining – mines, extracts and transports bitumen from oil sands deposits in Alberta, Canada, and upgrades the bitumen to produce and market synthetic crude oil and vacuum gas oil.

 As discussed in Note 6 to the consolidated financial statements, our Angola and Norway businesses are reflected as discontinued operations and are excluded from the International E&P segment in all periods presented. We sold our Angola assets in the first quarter of 2014 and our Norway business on October 15, 2014. Assets and liabilities are presented as held for sale in the consolidated balance sheets as of December 31, 2013 for our Angola business and September 30, 2014 for our Norway business.

Executive Summary

Our net sales volumes from continuing operations for the third quarter and first nine months of2014 averaged 417 thousand barrels of oil equivalent per day ("mboed") and 400 mboed compared to 403 mboed and 412 mboed for the third quarter and first nine months of2013. As we had only one oil lifting from Libya in the third quarter and first nine months of2014, a more representative comparison is net sales volumes from continuing operations excluding Libya. Excluding Libya, our net sales volumes from continuing operations increased 8 percent and 6 percent in the third quarter and first nine months of2014. The continued ramp up of production from our U.S. resource plays was the most significant contributor to the 2014 increases when comparing results excluding Libya, partially offset by decreases from the U.K. and Equatorial Guinea. Net sales volumes related to the Angola and Norway discontinued operations for the third quarter and first nine months of2014 averaged 58 mboed and 68 mboed compared to 77 mboed and 90 mboed for the third quarter and first nine months of2013, ranging from 12 to 18 percent of total company net sales volumes in those periods.

Income from continuing operations per diluted share was $0.45 for the third quarter of 2014, a decrease of 20 percent over the same 2013 period, as a result of lower income from our International E&P segment driven primarily by lower net sales volumes combined with lower liquid hydrocarbon price realizations across all segments. In the first nine months of 2014, income from continuing operations per diluted share increased by 38 percent from the comparable 2013 period to $1.56, reflecting higher income from our North America E&P and Oil Sands Mining segments driven primarily by continued growth in net sales volumes from our U.S. resource plays partially offset by lower commodity prices. This increase in the first nine months of 2014 also reflects the $0.84 per diluted share after-tax gain on the sale of our Angola assets in the first quarter of 2014 and the $0.48 per diluted share after-tax non-cash charge for unproved property impairments on Eagle Ford leases that either expired or that we did not expect to drill or extend in the first quarter of 2013.

Key Operating and Financial Activities

In the third quarter of 2014, notable activities were:

• Increased average net sales volumes from the three U.S. resource plays to 192 mboed, up 43 percent from same quarter of last year

• Continued strong pace in the Eagle Ford with 87 gross operated wells to sales, up 14 percent from the second quarter of 2014

• Eight gross operated Austin Chalk wells brought to sales during the quarter, all within previously delineated acreage; 16 additional wells being drilled, completed or awaiting first production

• Nineteen gross operated Bakken wells brought to sales, of which eight are piloting enhanced completions

• Incremental drilling rig added in the Bakken as of late September to provide additional capacity for high-density spacing and enhanced completion pilots

• Six gross operated wells brought to sales in the Oklahoma Resource Basins, of which four were in the South Central Oklahoma Oil Province ("SCOOP") and two in the Southern Mississippi Trend

• Began drilling the operated Key Largo exploration well in the Gulf of Mexico

• Brought two successful South Brae infill wells online in the U.K. North Sea

• Recorded 96 percent average operational availability for operated assets

Significant fourth quarter activity through November 4, 2014 includes:

• Closed sale of our Norway business on October 15, 2014 for approximately $2.1 billion in proceeds

• Executed agreements in October to add approximately 12,000 net acres to SCOOP position, including prospective acres for the Springer formation

North America E&P segment average net sales volumes in the third quarter and first nine months of2014increased 25 percent and 15 percent when compared to the third quarter and first nine months of2013.  Net liquid hydrocarbon sales volumes increased 47 thousand barrels per day ("mbbld") and 32 mbbld for the third quarter and first nine months of2014, and net natural gas sales volumes increased 20 million cubic feet per day ("mmcfd") and decreased 15 mmcfd for the third quarter and first nine months of2014, primarily reflecting continued growth from the combined U.S. resource plays, partially offset by the shut-in and exit from Powder River Basin operations. The negative impact of extreme winter weather on availability and completion operations in the first quarter of 2014 is reflected in the smaller increase in net liquid hydrocarbon sales volumes for the nine-month period. Reduced net natural gas sales volumes for the nine-month period were primarily related to the Powder River Basin and to the January 2013 sale of our Alaska assets, somewhat offset by increases in associated natural gas production from our U.S. resource plays.

Eagle Ford – Average net sales volumes from Eagle Ford were 117 mboed and 105 mboed in the third quarter and first nine months of2014 compared to 82 mboed and 78 mboed in the same 2013 periods, for increases of 43 percent and 35 percent. Approximately 64 percent of third quarter sales was crude oil and condensate, 18 percent was natural gas liquids ("NGLs") and 18 percent was natural gas.

Enhanced completion design in the Eagle Ford continues to deliver strong results as the growing population of these wells achieving 180-day cumulative production continues to average 25 percent improvement in volumes as compared to the previous completion design. During the third quarter of 2014, we reached total depth on 93 gross operated wells and brought 87 gross

22

operated wells to sales, compared to 70 reaching total depth and 71 brought to sales in the third quarter of 2013. During the first nine months of 2014, we reached total depth on 264 gross operated wells and brought 221 gross operated wells to sales, compared to 228 reaching total depth and 219 brought to sales in the same 2013 period. Our third quarter of 2014 average spud-to-total depth time was 13 days compared to 12 days in the same 2013 period. Our high-density pad drilling continues to average four wells per pad in 2014. This higher pad density and the longer laterals being drilled in 2014 contribute to the slightly higher spud-to-total depth time in 2014.

Included with the Eagle Ford well counts noted above, we brought online eight Austin Chalk wells, all drilled within the previously delineated acreage. Sixteen additional Austin Chalk wells are currently being drilled, completed or awaiting first production and we expect to complete a total of 30 wells in the Austin Chalk for 2014.

Bakken – Average net sales volumes from the Bakken shale were 56 mboed and 50 mboed in the third quarter and first nine months of2014 compared to 38 mboed in the same 2013 periods, for increases of 47 percent and 32 percent. Our Bakken production averages approximately 89 percent crude oil, six percent NGLs and five percent natural gas. During the third quarter of 2014, we reached total depth on 25 gross operated wells and brought 19 gross operated wells to sales, compared to 21 reaching total depth and 21 brought to sales in the third quarter of 2013. During the first nine months of 2014, we reached total depth on 60 gross operated wells and brought 49 gross operated wells to sales compared to 61 reaching total depth and 56 brought to sales in the same 2013 period. Our third quarter average time to drill a well was 16 days spud-to-total depth, compared to 18 days in the same 2013 period. We recompleted 16 wells in the Hector and Ajax areas during the third quarter of 2014, with 13 of these wells brought to sales.

Three of four high-density spacing pilots have begun drilling, with each pad comprised of six Middle Bakken and six Three Forks first bench wells. We continue to execute an enhanced completion design pilot program, including elevated proppant volumes, hybrid slickwater fracs, increased stages and cemented liners. Of the 19 Bakken wells brought to sales in the quarter, eight are piloting enhanced completions. In late September an incremental drilling rig was added in the Bakken to provide additional capacity for high-density spacing and enhanced completion pilots.

Oklahoma resource basins – Net sales volumes from the Oklahoma resource basins averaged 19 mboed and 17 mboed in the third quarter and first nine months of2014 compared to 15 mboed and 13 mboed in the comparable 2013 periods, for increases of 27 percent and 31 percent. Approximately 42 percent of third quarter 2014 sales was liquid hydrocarbons and 58 percent natural gas. During the third quarter of 2014, we reached total depth on four gross operated wells and brought six gross operated wells to sales. Of the wells brought to sales, four were in the SCOOP and two in the Southern Mississippi Trend. We plan to add two incremental rigs in the Oklahoma Resource Basins by year end. During the first nine months of 2014, we reached total depth on 15 gross operated wells and brought ten gross operated wells to sales, compared to eight reaching total depth and nine brought to sales in the same 2013 period.

Wyoming – Operated production at the Powder River Basin field ceased in March 2014. Plug and abandonment activities are expected to be substantially complete in the fourth quarter of 2014.

North America E&P--Exploration

Gulf of Mexico –The operated Key Largo exploration prospect, located on Walker Ridge Block 578, spud in September 2014 as the first well of a multi-year Gulf of Mexico exploration program with a new-build deepwater drillship. We are operator and hold a 60 percent working interest in the prospect.

An exploration well was spud on the Perseus prospect, located on Desoto Canyon Block 231 in September 2014. We hold a 30 percent non-operated working interest in the prospect.

The second appraisal well on the non-operated Shenandoah prospect was spud in late May 2014 and is still drilling. The well is located on Walker Ridge Block 52, in which we hold a 10 percent working interest.

North America E&P--Acquisitions

In an asset acquisition that closed August 2014, we added acreage to our Oklahoma resource position at a cost of approximately $80 million before final settlement adjustments.

International E&P segment average net sales volumes in the third quarter and first nine months of2014decreased 27 percent and 27 percent when compared to the third quarter and first nine months of2013.   We had lower oil sales from Libya in 2014 as a result of third party labor strikes at the Es Sider terminal. Excluding Libya, net sales volumes decreased 20 percent in the third quarter of 2014 and decreased 7 percent in the first nine months of 2014 compared to the same 2013 periods. The third quarter of 2014 net sales volume decrease, excluding Libya, is primarily as a result of the timing of liquid hydrocarbon liftings from the U.K., lower reliability at the non-operated methanol facility in Equatorial Guinea and planned maintenance activities at the non-operated Forties Pipeline System that lowered operational availability across the Brae complex in the U.K. The net sales volume decrease for the first nine months of 2014, excluding Libya, is primarily related to reliability issues at the non-operated U.K. Foinaven field as well as natural production decline within the U.K. Brae fields, in addition to the third quarter impacts discussed above.

 Equatorial Guinea – Average net sales volumes were 97 mboed and 104 mboed in the third quarter and first nine months of2014 compared to 109 mboed and 104 mboed in the same 2013 periods. Third quarter of 2014 net sales volumes were lower primarily as a result of temporary production curtailments due to unplanned maintenance on the main condensate line as well as lower reliability at the non-operated methanol facility.

An outbreak of the Ebola virus has existed in certain regions of West Africa (Guinea, Liberia, Sierra Leone) for several months.  Although neither Equatorial Guinea nor any other African country in which we have business activities has been impacted by Ebola to date, our business operations may be adversely affected through travel or other restrictions. We continue to monitor the situation and are working closely with appropriate external parties to maintain business continuity and the health and well-being of our staff.

United Kingdom – Average net sales volumes were 9 mboed and 15 mboed in the third quarter and first nine months of2014 compared to 24 mboed in the same 2013 periods, for decreases of 63 percent and 38 percent, primarily due to the timing of liquid hydrocarbon liftings, planned maintenance activities on the non-operated Forties Pipeline System in the third quarter of 2014, reliability issues at the non-operated Foinaven field and natural decline within the Brae fields. Overall, operating availability was lower for all U.K. assets in 2014 due to planned and unplanned maintenance activities. We brought two South Brae infill wells online in the third quarter of 2014. A third South Brae well and a new West Brae well are planned to come online in the first quarter of 2015.

24

Libya – In July 2014, Libya's National Oil Corporation rescinded force majeure associated with third-party labor strikes at the Es Sider terminal. Our first 2014 lifting occurred in August, and was sourced from existing inventory at the terminal.  Production from the Waha concessions resumed in August 2014; however, considerable uncertainty remains around future production and sales levels. 

International E&P--Exploration

Kurdistan Region of Iraq – We resumed testing of the Jisik-1 exploration well on the operated Harir Block following suspension of certain operations due to security concerns in the region and continue to closely monitor the situation. In the fourth quarter of 2014, we will commence a 2D seismic program and expect to spud the Mirawa-2 appraisal well. We hold a 45 percent operated working interest in the Harir Block.

On the non-operated Sarsang Block, testing continues on the East Swara Tika-1 exploratory well which reached a total depth of approximately 13,000 feet in June 2014. The co-venturers declared the Swara Tika discovery commercial in May 2014 and filed a field development plan in June. Discussions are ongoing with the Ministry of Natural Resources to finalize the Swara Tika field development plan. Testing of the Mangesh well was finalized and the well costs were charged to dry well expense in the second quarter of 2014. Due to a contract amendment in April 2014, we hold a 20 percent non-operated working interest in the Sarsang block.

Construction of the phase one production facility on the non-operated Atrush Block continues with first oil expected in 2015. The Chiya Khere-5 development well (formerly Atrush-5) reached total depth in late June 2014. The well will be tested prior to final completion and tie-in to the phase one production facility. The Atrush-4 development well reached total depth in January 2014, completed testing in April 2014 and has been suspended as a future producer. We hold a 15 percent non-operated working interest in the Atrush Block.

Equatorial Guinea – An exploration well on the Sodalita West prospect is expected to spud by the end of 2014 as the first of two offshore exploration wells targeting oil-prone plays.

Kenya – The Sala-2 appraisal well spud in the third quarter of 2014, did not encounter commercial hydrocarbons, and the well costs were charged to dry well expense in the quarter. The Sala-1 exploration well was spud in February 2014 on the eastern side of Block 9 and made a natural gas discovery in the second quarter of 2014. The well was drilled to a total depth of approximately 10,000 feet and analysis indicated three zones of interest over a 3,280-foot gross interval which were subsequently drill-stem tested. We hold a 50 percent non-operated working interest in Block 9 with the option to operate any commercial development.

Ethiopia – Two wells were drilled on the South Omo Block: the Shimela-1 well, which reached total depth in May 2014, and the Gardim-1 well, which reached total depth in July 2014. Neither well encountered commercial hydrocarbons and the well costs were charged to dry well expense in the second quarter of 2014. We hold a 20 percent non-operated interest in the South Omo Block.

Early in 2014, we increased our acreage in Ethiopia through a farm-in to the Rift Basin Area Block with 10.5 million gross acres. We are in the process of acquiring 2D seismic and plan to drill an appraisal well in 2015. We hold a 50 percent non-operated working interest in the block with the option to operate if a discovery is made.

Gabon – In August 2014, we signed an exploration and production sharing contract for Gabon offshore Block G13, which was subsequently re-named Tchicuate. Located in the deepwater, pre-salt play, the block encompasses 275,000 acres; and, acquisition of 3D seismic is planned to commence in early November 2014. We hold a 100 percent participating interest and operatorship in the block. In the event of development, the Republic of Gabon will assume a 20 percent financed interest in the contract upon commencement of production. The State holds additional rights to participate in the block in the future as a co-investor.

 Poland – During the first quarter of 2014, we relinquished our remaining four operated concessions to the government.

International E&P--Dispositions

In June 2014, we entered into an agreement to sell our Norway business, including the operated Alvheim floating production, storage and offloading vessel, 10 operated licenses and a number of non-operated licenses on the Norwegian Continental Shelf in the North Sea,with an effective date of January 1, 2014. The transaction closed on October 15, 2014 for approximately $2.1 billion in proceeds.

The Norway business is excluded from the International E&P segment results and is reported as discontinued operations. Average net sales volumes from Norway were 58 mboed and 66 mboed in the third quarter and first nine months of2014 compared to 68 mboed and 81 mboed in the same 2013 periods. The decrease for the quarter was primarily related to a 12-day planned turnaround at Alvheim versus a planned 7-day turnaround in same quarter of 2013, as well as natural field decline. Alvheim was also impacted in the first quarter of 2014 by severe winter weather which resulted in eight days of curtailed production.

25

In the first quarter of 2014, we closed the sales of our non-operated 10 percent working interests in the Production Sharing Contracts and Joint Operating Agreements for Angola Blocks 31 and 32 for aggregate proceeds of approximately $2 billion. See Note 6 to the consolidated financial statements for information about these dispositions.

Oil Sands Mining

 Our Oil Sands Mining operations consist of a 20 percent non-operated working interest in the Athabasca Oil Sands Project.  Our net synthetic crude oil sales volumes were 55 mbbld and 49 mbbld in the third quarter and first nine months of2014 compared to 49 mbbld and 47 mbbld in the same periods of 2013. The increase for the third quarter of 2014 was the result of improved operational availability at the upgrader and mines and higher beginning bitumen inventories. Comparison of sales volumes for the nine-month periods reflects lower mine reliability and nine days of planned mine maintenance in the first quarter of 2014 and a planned turnaround in the second quarter of 2013.

Crude oil and condensate – Our crude oil and condensate price realizations may differ from the benchmark due to the quality and location of the product. Crude oil benchmark prices decreased for third quarter and first nine months of2014 compared to the same 2013 periods due to a decline in crude oil prices because of increased supply, weak global demand and other geopolitical factors. This price decline continued after quarter end with WTI averaging $84.34 per bbl in October 2014.  

27

Natural gas liquids – The majority of our NGL volumes are sold at reference to Mont Belvieu prices. Average Mount Belvieu NGL prices for the third quarter of 2014 were modestly lower than for the same 2013 period. This was primarily due to softer ethane prices, due to a higher incidence of downtime in the demand driven petroleum chemical industry, and lower crude oil prices. Our net NGL sales volumes continue to grow due to development of our U.S. resource plays with increases of 29 percent and 27 percent during the third quarter and first nine months of2014 compared to the same 2013 periods.

Natural gas –A significant portion of our natural gas production in the U.S. is sold at bid-week prices, or first-of-month indices relative to our specific producing areas.  Average Henry Hub settlement prices for natural gas were higher in the third quarter of 2014 compared to the same 2013 period primarily because of incremental demand generated from significantly lower storage levels.

International E&P

The following table presents our average price realizations and the related benchmark for crude oil for the third quarter and first nine months of2014 and 2013.

^(a)  Primarily represents fixed prices under long-term contracts with Alba Plant LLC, Atlantic Methanol Production Company LLC and Equatorial Guinea LNG Holdings Limited, which are equity method investees.  We include our share of income from each of these equity method investees in our International E&P segment.

Liquid hydrocarbons – Our U.K. liquid hydrocarbon production is generally sold in relation to the Brent crude benchmark. Our liquid hydrocarbon production from Equatorial Guinea includes condensate and NGLs that receive lower prices than crude oil. During the third quarter of 2014, crude oil prices declined driven by weaker demand and increased supply, along with continued global economy and geopolitical factors. This price decline continued after quarter end with Brent averaging $88.05 per bbl in October 2014.

Natural gas –Our major international natural gas-producing regions are the U.K. and Equatorial Guinea.  Natural gas prices in Europe have been considerably higher than in the U.S. in recent years.  In the case of Equatorial Guinea, our natural gas sales are subject to fixed-price, term contracts, making realized prices in this area less volatile; therefore, our reported average natural gas realized prices for the International E&P segment will not fully track market price movements.

Oil Sands Mining

 The Oil Sands Mining segment produces and sells various qualities of synthetic crude oil. Output mix can be impacted by operational reliability or planned unit outages at the mines or upgrader. Sales prices for roughly two-thirds of the normal output mix have historically tracked movements in WTI and one-third have historically tracked movements in the Canadian heavy crude oil marker, primarily Western Canadian Select ("WCS"). Comparing the corresponding 2014 and 2013 periods, the WCS discount to WTI widened in the third quarter by $2.80 per barrel; however, in the first nine months of 2014, the WCS discount to WTI narrowed by $1.81 per barrel.

The operating cost structure of our Oil Sands Mining operations is predominantly fixed and therefore many of the costs incurred in times of full operation continue during production downtime. Per-unit costs are sensitive to production rates. Key variable costs are natural gas and diesel fuel, which track commodity markets such as the Canadian Alberta Energy Company ("AECO") natural gas sales index and crude oil prices.

International E&P sales and other operating revenues decreased 55 percent and 57 percent in the third quarter and first nine months of2014 from the comparable 2013 periods. The decreases were primarily due to the lower liquid hydrocarbon net sales volumes previously discussed, combined with lower average price realizations for both liquid hydrocarbons and natural gas.

Unrealized gains and losses on crude oil derivative instruments are included in total sales and other operating revenues but are not allocated to the segments. In both the third quarter and first nine months of 2013, the net unrealized loss on crude oil derivative instruments was $61 million. There were no crude oil derivative instruments in the third quarter and first nine months of2014.

Marketing revenuesdecreased$112 million and increased $118 million in the third quarter and first nine months of2014 from the comparable prior-year periods. The decrease in the third quarter of 2014 is related primarily to lower marketing activity levels and crude oil prices in the North America E&P segment. The increase in the first nine months of 2014 is primarily due to higher marketing activity levels in both the North America E&P and OSM segments. Marketing activities include the purchase of commodities from third parties for resale and serve to aggregate volumes in order to satisfy transportation commitments as well as to achieve flexibility within product types and delivery points. Since the volume of marketing activity is based on market dynamics, it can fluctuate from period to period.

Income from equity method investmentsdecreased $25 million and increased $37 million in the third quarter and first nine months of2014 from the comparable 2013 periods. The decrease in the third quarter of 2014 is primarily due to reliability issues in Equatorial Guinea at the non-operated methanol facility and lower average price realizations. The increase in the first nine months of 2014 is primarily due to higher earnings from our LNG operations in Equatorial Guinea as a result of higher average price realizations and a turnaround in the second quarter of 2013.

Net loss on disposal of assets in the first nine months of 2014 includes the loss on the sale of non-core acreage located in the far northwest portion of the Williston Basin. See Note 6 to the consolidated financial statements for further details on dispositions.

Production expensesincreased$53 million in the third quarter of 2014 from the third quarter of 2013. North America E&P segment production expenses increased $28 million primarily related to higher net sales volumes in the U.S. resource plays. OSM segment production expenses increased $25 million primarily as a result of higher net sales volumes.

In the first nine months of 2014, production expenses increased $72 million compared to the same 2013 period. North America E&P segment production expenses increased $77 million primarily related to higher net sales volumes in the U.S. resource plays. International E&P segment production expenses increased $38 million and included $11 million for non-recurring riser repairs in Equatorial Guinea during the first quarter of 2014 and $5 million related to a turnaround at Brae in the U.K. during the second quarter of 2014. Lower sales volumes across the International E&P segment contributed to the higher production expense rate (production expense per barrel of oil equivalent, or "boe"). OSM segment production expenses decreased $43 million in the first nine months of 2014 due to the 2013 turnaround and lower contract services and contract labor costs in 2014.

The following table provides production expense rates for each segment:

	Three Months Ended September 30,				Nine Months Ended September 30,
($ per boe)	2014		2013		2014		2013
Production Expense Rate
North America E&P		$10.16		$11.18		$10.52		$10.72
International E&P		$10.48		$7.64		$9.34		$5.96
Oil Sands Mining (a)		$37.38		$40.47		$44.73		$47.30

^(a)  Production expense per synthetic crude oil barrel (before royalties) includes production costs, shipping and handling, taxes other than income and insurance costs and excludes pre-development costs.

Marketing costsdecreased$109 million and increased $120 million in the third quarter and first nine months of2014 from the comparable 2013 periods, consistent with the marketing revenues changes discussed above.

Exploration expenseswere $351 million lower in the first nine months of 2014 than in the comparable 2013 period. The first quarter of 2013 included $340 million in non-cash unproved property impairments on Eagle Ford leases that either expired or that we did not expect to drill or extend. The following table summarizes the components of exploration expenses:

31

	Three Months Ended September 30,				Nine Months Ended September 30,
(In millions)	2014		2013		2014		2013
Exploration Expenses
Unproved property impairments	$	39	$	35	$	140	$	458
Dry well costs	25		24		80		95
Geological and geophysical	10		8		27		44
Other	22		16		67		68
Total exploration expenses	$	96	$	83	$	314	$	665

Depreciation, depletion and amortization(“DD&A”) increased$80 million and $146 million in the third quarter and first nine months of2014 from the comparable 2013 periods.  Our segments apply the units-of-production method to the majority of their assets, including capitalized asset retirement costs; therefore, volumes have an impact on DD&A expense. The DD&A rate (expense per boe), which is impacted by changes in reserves and capitalized costs, can also cause changes to our DD&A.

Increased DD&A in the third quarter and first nine months of2014 primarily reflects the impact of higher North America E&P net sales volumes from our three U.S. resource plays; partially offset by lower International E&P segment sales volumes, as previously discussed.

The International E&P segment DD&A rate was lower in the third quarter and first nine months of2014 because a majority of our net sales volumes in the 2014 periods were from countries with lower DD&A rates.

	Three Months Ended September 30,				Nine Months Ended September 30,
($ per boe)	2014		2013		2014		2013
DD&A Rate
North America E&P		$26.54		$26.64		$26.65		$26.73
International E&P		$5.30		$8.18		$6.09		$6.28
Oil Sands Mining		$12.75		$12.43		$12.14		$12.27

Impairments are discussed in Note 13 to the consolidated financial statements.

Taxes other than incomeinclude production, severance and ad valorem taxes, primarily in the U.S., which tend to increase or decrease in relation to sales volumes and revenue. With the increase in North America E&P revenues and net sales volumes, taxes other than income increased $26 million and $55 million in the third quarter and first nine months of2014 from the comparable 2013 periods. The following table summarizes the components of taxes other than income:

	Three Months Ended September 30,				Nine Months Ended September 30,
(In millions)	2014		2013		2014		2013
Production and severance	$	69	$	50	$	191	$	151
Ad valorem	20		16		58		52
Other	26		23		70		61
Total	$	115	$	89	$	319	$	264

General and administrative expensesincreased$17 million in the third quarter of 2014 compared to the same 2013 period, primarily due to higher pension settlement expense as well as higher unallocated technical and operations support costs. The increase of $21 million in the first nine months of 2014 compared to the same 2013 period is primarily due to higher pension settlement expense and higher unallocated technical and operations support costs partially offset by lower employee related costs and less contract services.

Net interest and other in the third quarter and first nine months of2014 was a lower net expense by $16 million and $31 million compared to the same 2013 periods, primarily due to decreases in net foreign currency losses. In addition, a dividend was received in the first quarter of 2014 from a mutual insurance company of which we are an owner.

Provision for income taxesdecreased$210 million and $872 million in the third quarter and first nine months of2014 from the comparable 2013 periods, primarily as a result of reduced pretax income in Libya. See Note 9 to the consolidated financial statements for discussion of the effective tax rate.

Discontinued operations are presented net of tax. See the preceding Operations section and Note 6 to the consolidated financial statements for financial information about discontinued operations.

Segment Income

Segment income represents income from continuing operations excluding certain items not allocated to segments, net of income taxes, attributable to the operating segments. Our corporate and operations support general and administrative costs are not allocated to the operating segments. Unrealized gains or losses on crude oil derivative instruments, certain impairments, gains or losses on dispositions or other items that affect comparability also are not allocated to operating segments.

The following table reconciles segment income to net income:

	Three Months Ended September 30,						Nine Months Ended September 30,
(In millions)	2014			2013			2014			2013
North America E&P	$	292		$	242		$	836		$	404
International E&P	106			192			487			635
Oil Sands Mining	93			106			212			164

Items not allocated to segments, net of income taxes	(187		)	(144		)	(473		)	(408		)
Income from continuing operations	304			396			1,062			795
Discontinued operations (a)	127			173			1,058			583
Net income	$	431		$	569		$	2,120		$	1,378

^(a)  We sold our Angola assets in the first quarter of 2014 and closed the sale of our Norway business on October 15, 2014. The Angola and Norway businesses are reflected as discontinued operations in all periods presented.

 North America E&P segment incomeincreased $50 million and $432 million after-tax in the third quarter and first nine months of2014 compared to the same 2013 periods. The increases in both periods are primarily due to higher net sales volumes from the U.S. resource plays, partially offset by lower crude oil price realizations and expenses associated with the higher net sales volumes, such as production expenses and DD&A. Also impacting the comparison of the nine-month period was the previously discussed non-cash unproved property impairments in the first quarter of 2013.

International E&P segment incomedecreased $86 million and $148 million after-tax in the third quarter and first nine months of2014 compared to the same 2013 periods. The decreases in both periods are primarily a result of lower net sales volumes in the U.K and Equatorial Guinea and lower commodity price realizations, partially offset by reduced taxes and expenses associated with the lower sales volumes. Lower sales volumes from Libya impacted the decrease when comparing the nine-month periods. In addition, the second quarter of 2014 had higher exploration expenses due to dry wells, partially offset by higher earnings from our equity method LNG operations in Equatorial Guinea due to a turnaround in the second quarter of 2013.

Oil Sands Mining segment incomedecreased $13 million and increased $48 million after-tax in the third quarter and first nine months of2014 from the comparable 2013 periods. The third quarter 2014 decrease was primarily a result of lower price realizations partially offset by higher sales volumes. The increase in the first nine months of 2014 was primarily the result of lower production expenses and slightly higher net sales volumes.

Total uses of cash and cash equivalents	$	(6,268	)	$	(4,922	)

The increase in cash flows from discontinued operations during the first nine months of 2014 is mostly due to changes in working capital driven by substantially lower tax payments during the year as well as the timing of cash receipts from liftings. The third quarter 2014 tax payments were favorably impacted by tax synergies available to our Norway business as a result of the pending sale.

 Disposals of assets in the first nine months of 2014 primarily reflect the net proceeds from the sales of our interests in Angola Blocks 31 and 32. In the first nine months of 2013, net proceeds were primarily related to the sales of our Alaska assets and our interests in the Neptune gas plant and the DJ Basin.

Additions to property, plant and equipment are our most significant use of cash and cash equivalents. The following table shows capital expenditures related to continuing operations by segment and reconciles to additions to property, plant and equipment as presented in the consolidated statements of cash flows for the nine months ended September 30,2014 and 2013:

	Nine Months Ended September 30,
(In millions)	2014			2013

Additions to property, plant and equipment	$	3,639		$	3,383

Purchases of common stock are discussed in Note 18 to the consolidated financial statements.

Liquidity and Capital Resources

 Our main sources of liquidity are cash and cash equivalents, internally generated cash flow from operations, the issuance of notes, our committed revolving credit facility and sales of non-strategic assets. Our working capital requirements are supported

34

by these sources and we may issue commercial paper backed by our $2.5 billion revolving credit facility to meet short-term cash requirements.  Because of the alternatives available to us as discussed above, and access to capital markets through the shelf registration discussed below, we believe that our short-term and long-term liquidity is adequate to fund not only our current operations, but also our near-term and long-term funding requirements including our capital spending programs, dividend payments, defined benefit plan contributions, repayment of debt maturities, share repurchase program and other amounts that may ultimately be paid in connection with contingencies.

Capital Resources

Credit Arrangements and Borrowings

In May 2014, we amended our $2.5 billion unsecured revolving credit facility and extended the maturity to May 2019. See Note 16 to the consolidated financial statements for additional terms and rates. At September 30, 2014, we had no borrowings against our revolving credit facility and no amounts outstanding under our U.S. commercial paper program that is backed by the revolving credit facility.

At September 30, 2014, we had $6,423 million in long-term debt outstanding, $68 million of which is due within one year. We do not have any triggers on any of our corporate debt that would cause an event of default in the case of a downgrade of our credit ratings.

Shelf Registration

We have a universal shelf registration statement filed with the SEC under which we, as a "well-known seasoned issuer" for purposes of SEC rules, have the ability to issue and sell an indeterminate amount of various types of equity and debt securities. 

Asset Disposal

On October 15, 2014, we closed the sale of our Norway business for proceeds of approximately $2.1 billion. The first priority for the use of proceeds is organic reinvestment in our deep and growing U.S. unconventional portfolio. See Note 6 to the consolidated financial statements for additional discussion of the Norway disposal.

Cash-Adjusted Debt-To-Capital Ratio

 Our cash-adjusted debt-to-capital ratio (total debt-minus-cash and cash equivalents to total debt-plus-equity-minus-cash and cash equivalents) was 22 percent at September 30, 2014, compared to 25 percent at December 31, 2013.

Capital Requirements

 On October 29, 2014, our Board of Directors approved a dividend of 21 cents per share for the third quarter of 2014 payable December 10, 2014 to stockholders of record at the close of business on November 19, 2014.

As of September 30, 2014, we plan to make contributions of up to $24 million to our funded pension plans during the remainder of 2014.

In 2013, our Board of Directors increased the authorization for repurchases of our common stock by $1.2 billion, bringing the total authorized to $6.2 billion. As of September 30, 2014, we had repurchased a total of 121 million common shares at a cost

of $4.7 billion, including 29 million shares at a cost of $1 billion in the first six months of 2014. The remaining share repurchase authorization as of September 30, 2014 is $1.5 billion. Purchases under the repurchase program may be in either open market transactions, including block purchases, or in privately negotiated transactions. This program may be changed based upon our financial condition or changes in market conditions and is subject to termination prior to completion. The program’s authorization does not include specific price targets or timetables. The timing of purchases under the program will be influenced by cash generated from operations, proceeds from potential asset sales, cash from available borrowings and market conditions.

Contractual Cash Obligations

As of September 30, 2014, our total contractual cash obligations were consistent with December 31, 2013.

Environmental Matters

We have incurred and will continue to incur capital, operating and maintenance, and remediation expenditures as a result of environmental laws and regulations.  If these expenditures, as with all costs, are not ultimately reflected in the prices of our products and services, our operating results will be adversely affected.  We believe that substantially all of our competitors must comply with similar environmental laws and regulations.  However, the specific impact on each competitor may vary depending on a number of factors, including the age and location of its operating facilities, marketing areas and production processes.

There have been no significant changes to our environmental matters subsequent to December 31, 2013.

Other Contingencies

We are a defendant in a number of lawsuits arising in the ordinary course of business, including, but not limited to, royalty claims, contract claims and environmental claims.  While the ultimate outcome and impact to us cannot be predicted with certainty, we believe the resolution of these proceedings will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.  

Forward-Looking Statements

This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). All statements other than statements of historical fact included or incorporated by reference in this report, including without limitation statements regarding our operational, financial and growth strategies, planned capital expenditures and the impact thereof, growth activities and expectations, future drilling plans, timing and expectations, maintenance activities and the timing and impact thereof, well spud timing and expectations, operational outlook, future financial position, liquidity and capital resources, the planned use of proceeds from the sale of our Norway business, and the plans and objectives of our management for our future operations, are forward-looking statements. In addition, many forward-looking statements may be identified by the use of forward-looking terminology such as “anticipates,” “believes,” “estimates,” “expects,” “targets,” “plans,” “projects,” “could,” “may,” “should,” “would” or similar words indicating that future outcomes are uncertain. While we believe that our assumptions concerning future events are reasonable, we can give no assurance that these expectations will prove to be correct. A number of factors could cause results to differ materially from those indicated by such forward-looking statements including, but not limited to:

• conditions in the oil and gas industry, including the level of supply or demand for liquid hydrocarbons and natural gas and the impact on the price of liquid hydrocarbons and natural gas;

• changes in political or economic conditions in key operating markets, including international markets;

• the amount of capital available for exploration and development;

• timing of commencing production from new wells;

• drilling rig availability;

• availability of materials and labor;

• the inability to obtain or delay in obtaining necessary government or third-party approvals and permits;

• non-performance by third parties of their contractual obligations;

• unforeseen hazards such as weather conditions, acts of war or terrorist acts and the governmental or military response thereto;

• changes in safety, health, environmental and other regulations;

• other geological, operating and economic considerations; and

• other factors discussed in Item 1. Business, Item 1A. Risk Factors, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, Item 7A. Quantitative and Qualitative Disclosures About Market Risk, and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2013, and those set forth from time to time in our filings with the SEC.

36

All forward-looking statements included in this report are based on information available to us on the date of this report. Except as required by law, we assume no duty to revise or update any forward-looking statements whether as a result of new information, future events or otherwise. All subsequent written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements contained throughout this report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

For a detailed discussion of our risk management strategies and our derivative instruments, see Item 7A. Quantitative and Qualitative Disclosures About Market Risk in our 2013 Annual Report on Form 10-K. Additional disclosures regarding our open derivative positions, including underlying notional quantities, how they are reported in our consolidated financial statements and how their fair values are measured, may be found in Notes 13 and 14 to the consolidated financial statements.

The following table provides sensitivity analysis of the projected incremental effect of a hypothetical 10 percent change in interest rates on financial assets and liabilities as of September 30, 2014.

					Incremental
					Change in
(In millions)	Fair Value				Fair Value
Financial assets (liabilities): (a)
Interest rate swap agreements	$	5		(b)	$	5
Long-term debt, including amounts due within one year	$	(7,057	)	(b)(c)	$	(214	)

^(a)  Fair values of cash and cash equivalents, receivables, commercial paper, accounts payable and accrued interest approximate carrying value and are relatively insensitive to changes in interest rates due to the short-term maturity of the instruments.  Accordingly, these instruments are excluded from the table.

^(b)  Fair value was based on market prices where available, or current borrowing rates for financings with similar terms and maturities.

^(c)  Excludes capital leases.

The incremental change in fair value of our foreign currency derivative contracts of a hypothetical 10 percent change in exchange rates at September 30, 2014 would be $35 million.

Item 4. Controls and Procedures

An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer.  Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our company's design and operation of disclosure controls and procedures were effective as of September 30, 2014.  

During the third quarter of 2014, there were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Variable Interest Entity, Not Primary Beneficiary, Disclosures [Abstract]

Variable Interest Entity [Text Block]

Variable Interest Entity

The owners of the Athabasca Oil Sands Project, in which we hold a 20 percent undivided interest, contracted with a wholly owned subsidiary of a publicly traded Canadian limited partnership (“Corridor Pipeline”) to provide materials transportation capabilities among the Muskeg River and Jackpine mines, the Scotford upgrader and markets in Edmonton.  Costs under this contract are accrued and recorded on a monthly basis, with current liabilities of $3 million recorded at September 30, 2014, consistent with December 31, 2013.  This contract qualifies as a variable interest contractual arrangement, and the Corridor Pipeline qualifies as a variable interest entity (“VIE”).  We hold a variable interest but are not the primary beneficiary because our shipments are only 20 percent of the total; therefore, the Corridor Pipeline is not consolidated by us.  Our maximum exposure to loss as a result of our involvement with this VIE is the amount we expect to pay over the contract term, which was $586 million as of September 30, 2014.  The liability on our books related to this contract at any given time will reflect amounts due for the immediately previous month’s activity, which is substantially less than the maximum exposure over the contract term.

Accounting Standards Disclosure [Abstract]

Accounting Standards [Text Block]

Accounting Standards

Not Yet Adopted

In August 2014, the Financial Accounting Standards Board ("FASB") issued an update that requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in United States ("U.S.") auditing standards.  This standard is effective for us in the first quarter of 2017 and early adoption is permitted. We do not expect the adoption of this standard to have a significant impact on our consolidated results of operations, financial position or cash flows.

In May 2014, the FASB issued an update that supersedes the existing revenue recognition requirements. This standard includes a five-step revenue recognition model to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. Among other things, the standard also eliminates industry-specific revenue guidance, requires enhanced disclosures about revenue, provides guidance for transactions that were not previously addressed comprehensively, and improves guidance for multiple-element arrangements. This standard is effective for us in the first quarter of 2017 and should be applied retrospectively to each prior reporting period presented or with the cumulative effect of initially applying the update recognized at the date of initial application. Early adoption is not permitted. We are evaluating the provisions of this accounting standards update and assessing the impact, if any, it may have on our consolidated results of operations, financial position or cash flows.

In April 2014, the FASB issued an amendment to accounting standards that changes the criteria for reporting discontinued operations while enhancing related disclosures. Under the amendment, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization’s operations and financial results. Examples include disposal of a major geographic area, a major line of business, or a major equity method investment.  Expanded disclosures about the assets, liabilities, income and expenses of discontinued operations will be required.  In addition, disclosure of the pretax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting will be made in order to provide users with information about the ongoing trends in an organization’s results from continuing operations.  The amendments are effective for us in the first quarter of 2015 and early adoption is permitted. We did not elect early adoption of this amendment and do not expect its future adoption to have a significant impact on our consolidated results of operations, financial position or cash flows.

Recently Adopted

In June 2013, the FASB ratified the Emerging Issues Task Force consensus which requires that an unrecognized tax benefit (or a portion thereof) be presented as a reduction to a deferred tax asset for an available net operating loss carryforward, a similar tax loss or tax credit carryforward. This accounting standards update was effective for us beginning in the first quarter of 2014 and is required to be applied prospectively. Adoption of this standard did not have a significant impact on our consolidated results of operations, financial position or cash flows.

In February 2013, an accounting standards update was issued to provide guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, except for obligations such as asset retirement and environmental obligations, contingencies, guarantees, income taxes and retirement benefits, which are separately addressed within U.S. GAAP. This accounting standards update was effective for us beginning in the first quarter of 2014 and is required to be applied retrospectively. Adoption of this standard did not have a significant impact on our consolidated results of operations, financial position or cash flows.

Debt Disclosure [Text Block]

 Debt

As of September 30, 2014, we had no borrowings against our revolving credit facility, as described below, or under our U.S. commercial paper program that is backed by the revolving credit facility.

In May 2014, we amended our $2.5 billion unsecured revolving credit facility (the "Credit Facility"), and extended the maturity to May 2019. Terms of this amended Credit Facility include the ability to request two one-year extensions and an option to increase the commitment amount by up to an additional $1.0 billion, subject to the consent of any increasing lenders, and sub-facilities for swing-line loans and letters of credit up to an aggregate amount of $100 million and $500 million.  Fees on the unused commitment of each lender range from 8 basis points to 22.5 basis points depending on our credit ratings. Borrowings under the Credit Facility bear interest, at our option, at either (a) an adjusted LIBOR rate plus a margin ranging from 87.5 basis points to 150 basis points depending on our credit ratings or (b) the Base Rate plus a margin ranging from 0 basis points to 50 basis points depending on our credit ratings.  Base Rate is defined as a per annum rate equal to the greatest of (a) the prime rate, (b) the federal funds rate plus one-half of one percent or (c) LIBOR for a one-month interest period plus 1 percent.

The agreement contains a covenant that requires our ratio of total debt to total capitalization not to exceed 65 percent as of the last day of each fiscal quarter.  If an event of default occurs, the lenders holding more than half of the commitments may terminate the commitments under the Credit Facility and require the immediate repayment of all outstanding borrowings and the cash collateralization of all outstanding letters of credit under the Credit Facility.

In the third quarter of 2013, our production in Libya was interrupted by third-party labor strikes at the port facilities, which later resulted in a blockade of the Es Sider terminal from which we export oil.  In July 2014, Libya's National Oil Corporation rescinded force majeure associated with these third-party labor strikes at the Es Sider terminal. Our first 2014 lifting occurred in August, and was sourced from existing inventory at the terminal.  Production from the Waha concessions resumed in August 2014; however, considerable uncertainty remains around future production and sales levels.  As of September 30, 2014, our net property, plant and equipment investment in Libya is approximately $771 million. We and our partners in the Waha concessions continue to assess the situation and the condition of our assets in Libya. Our periodic assessment of the carrying value of our net property, plant and equipment in Libya specifically considers the net investment in the assets, the duration of our concessions and the reserves anticipated to be recoverable in future periods.

Exploratory well costs capitalized greater than one year after completion of drilling were $155 million as of September 30, 2014 (including $29 million related to Norway project costs which are reflected in noncurrent assets held for sale) and $281 million as of December 31, 2013 (including $70 million related to Norway project costs). This $126 million net decrease was the result of a $153 million reduction due to the sale of our interests in Angola Blocks 31 and 32 and a decrease of $39 million due to the commencement of drilling at the Boyla development and sanction of the Viper project offshore Norway, partially offset by an increase of $66 million for Diaba License G4-223 offshore Gabon where the Diaman-1B well reached total depth in the third quarter of 2013. We are analyzing new 3D seismic, integrated with existing technical data, in order to finalize the next steps in the exploration program on the Diaba License.

2014 - International E&P Segment

In June 2014, we entered into an agreement to sell our Norway business, including the operated Alvheim floating production, storage and offloading vessel, 10 operated licenses and a number of non-operated licenses on the Norwegian Continental Shelf in the North Sea, with an effective date of January 1, 2014.  The transaction closed on October 15, 2014. After adjustment for debt, net working capital and interest on the net purchase price, we received proceeds of approximately $2.1 billion and expect to record a pretax gain of approximately $1.4 billion in the fourth quarter of 2014.

Our Norway business is reflected as discontinued operations in the consolidated statements of income and the consolidated statements of cash flows for all periods presented. Select amounts reported in discontinued operations were as follows:

In the first quarter of 2014, we closed the sales of our non-operated 10 percent working interests in the Production Sharing Contracts and Joint Operating Agreements for Angola Blocks 31 and 32 for aggregate proceeds of approximately $2 billion. Included in the after-tax gain is a deferred tax benefit reflecting our ability to utilize foreign tax credits that otherwise would have needed a valuation allowance.

Acquisitions

2014 - North America Exploration and Production ("E&P") Segment

In an asset acquisition that closed August 2014, we added acreage to our Oklahoma resource position at a cost of approximately $80 million before final settlement adjustments.

2013 - North America E&P Segment

In July 2013, we acquired additional acreage in the Eagle Ford in a transaction valued at $97 million, including a carried interest of $23 million which was fully satisfied as of September 30, 2014. The pro forma impact of this transaction is not material to our consolidated statements of income for any periods presented.

The transaction was accounted for as a business combination with the fair values of assets acquired and liabilities assumed measured primarily using an income approach, specifically utilizing a discounted cash flow model. The estimated fair values were based on significant inputs not observable in the market, and therefore represent Level 3 measurements. Significant inputs included estimated reserve volumes, the expected future production profile, estimated commodity prices, assumptions regarding future operating and development costs and a discount rate of approximately 10 percent. The entire up-front cash consideration of $74 million was allocated to property, plant and equipment at the acquisition date.

Interest rate swaps are measured at fair value with a market approach using actionable broker quotes which are Level 2 inputs.  Foreign currency forwards are measured at fair value with a market approach using third-party pricing services, such as Bloomberg L.P., which have been corroborated with data from active markets for similar assets or liabilities, and are Level 2 inputs.

Fair Values - Nonrecurring

The following table shows the values of assets, by major category, measured at fair value on a nonrecurring basis in periods subsequent to their initial recognition.

	Three Months Ended September 30,

	2014				2013
(In millions)	Fair Value		Impairment		Fair Value		Impairment
Long-lived assets held for use	$	43	$	130	$	5	$	49

All long-lived assets held for use that were impaired in the first nine months of 2014 and 2013 were held by our North America E&P segment. The fair values of each were measured using an income approach based upon internal estimates of future production levels, prices and discount rate, all of which are Level 3 inputs.  Inputs to the fair value measurement included reserve and production estimates made by our reservoir engineers, estimated commodity prices adjusted for quality and location differentials, and forecasted operating expenses for the remaining estimated life of the reservoir.

The Ozona development in the Gulf of Mexico ceased producing in the first quarter of 2013 and a $21 million impairment was recorded. In the first nine months of 2014, we recorded additional impairments of $30 million at Ozona as a result of estimated abandonment cost revisions.

In the third quarter of 2014, impairments of $53 million were recorded to certain other Gulf of Mexico properties, as a result of estimated abandonment cost and other revisions, to an aggregate fair value of $19 million.

Also in the third quarter of 2014, two additional fields were impaired a total of $47 million to an aggregate fair value of $24 million primarily due to lower forecasted commodity prices.

In the first quarter of 2013, as a result of our decision to wind down operations in the Powder River Basin due to poor economics, an impairment of $15 million was recorded.

Other impairments of long-lived assets held for use by our North America E&P segment in the first nine months of 2013 were a result of reduced drilling expectations, reductions of estimated reserves or declining commodity prices.

Crude oil prices began declining in the third quarter of 2014 and continued to decrease in October 2014. A period of sustained low commodity prices could result in additional non-cash impairment charges related to our assets in future periods.

Fair Values – Financial Instruments

Our current assets and liabilities include financial instruments, the most significant of which are receivables, commercial paper and payables. We believe the carrying values of our receivables, commercial paper and payables approximate fair value. Our fair value assessment incorporates a variety of considerations, including (1) the short-term duration of the instruments, (2) our investment-grade credit rating, and (3) our historical incurrence of and expected future insignificance of bad debt expense, which includes an evaluation of counterparty credit risk.

The following table summarizes financial instruments, excluding current receivables, commercial paper, current payables, capital leases and derivative financial instruments, and their reported fair value by individual balance sheet line item at September 30, 2014 and December 31, 2013.

	September 30, 2014				December 31, 2013
	Fair		Carrying		Fair		Carrying
(In millions)	Value		Amount		Value		Amount
Financial assets
Other noncurrent assets	$	194	$	189	$	154	$	147

Total financial liabilities	$	7,164	$	6,557	$	7,084	$	6,587

^(a)    Excludes capital leases.

Fair values of our financial assets included in other noncurrent assets and of our financial liabilities included in other current liabilities and deferred credits and other liabilities are measured using an income approach. Most inputs are internally generated, which results in a Level 3 classification. Estimated future cash flows are discounted using a rate deemed appropriate to obtain the fair value.

Most of our long-term debt instruments are publicly-traded. A market approach, based upon quotes from major financial institutions, which are Level 2 inputs, is used to measure the fair value of such debt. The fair value of our debt that is not publicly-traded is measured using an income approach. The future debt service payments are discounted using the rate at which we currently expect to borrow. All inputs to this calculation are Level 3.

Income Taxes

Income Tax Disclosure [Abstract]

Income Tax Disclosure [Text Block]

Income Taxes

The effective income tax rate is influenced by a variety of factors including the geographic and functional sources of income and the relative magnitude of these sources of income. The difference between the total provision and the sum of the amounts allocated to segments is reported in the “Not Allocated to Segments” column of the tables in Note 7.

Our effective income tax rates on continuing operations for the first nine months of 2014 and 2013 were 32 percent and 63 percent.  The decrease in the effective tax rate on continuing operations in the first nine months of 2014 is primarily due to a decrease in pretax income from Libya operations, where the tax rate is in excess of 90 percent.

The tax provision (benefit) applicable to Libyan ordinary income (loss) was recorded as a discrete item in the first nine months of 2014 and 2013.  Excluding Libya, the effective tax rates on continuing operations would be 32 percent and 36 percent for the first nine months of 2014 and 2013. In Libya, there remains uncertainty around future production and sales levels. Reliable estimates of 2014 and 2013 Libyan annual ordinary income from our operations could not be made and the range of possible scenarios in the worldwide annual effective tax rate calculation demonstrates significant variability.  Thus, for the first nine months of 2014 and 2013, estimated annual effective tax rates were calculated excluding Libya and applied to consolidated ordinary income.

In the second quarter of 2014, we reviewed our foreign operations, including the disposition of Norway, and concluded that our foreign operations do not have the same level of immediate capital needs as previously expected.  Therefore, we no longer intend for previously unremitted foreign earnings of $746 million associated with our United Kingdom ("U.K.") operations to be permanently reinvested outside the U.S.  Foreign tax credits associated with these earnings would be sufficient to offset any incremental U.S. tax liabilities.  The remaining undistributed income of certain consolidated foreign subsidiaries for which no U.S. deferred income tax provision has been recorded because we intend to permanently reinvest such income in our foreign operations amounted to $994 million at September 30, 2014.  If such income were not permanently reinvested, income tax expense of approximately $348 million would be recorded, not including potential utilization of foreign tax credits.

Segment Reporting [Abstract]

Segment Information [Text Block]

Segment Information

  We have three reportable operating segments.  Each of these segments is organized based upon both geographic location and the nature of the products and services it offers.

• North America E&P ("N.A. E&P") – explores for, produces and markets liquid hydrocarbons and natural gas in North America;

• International E&P ("Int'l E&P") – explores for, produces and markets liquid hydrocarbons and natural gas outside of North America and produces and markets products manufactured from natural gas, such as liquefied natural gas ("LNG")and methanol, in Equatorial Guinea; and

• Oil Sands Mining (“OSM”) – mines, extracts and transports bitumen from oil sands deposits in Alberta, Canada, and upgrades the bitumen to produce and market synthetic crude oil and vacuum gas oil.

Information regarding assets by segment is not presented because it is not reviewed by the chief operating decision maker (“CODM”).  Segment income represents income from continuing operations excluding certain items not allocated to segments, net of income taxes, attributable to the operating segments. Our corporate and operations support general and administrative costs are not allocated to the operating segments. These costs primarily consist of employment costs (including pension effects), professional services, facilities and other costs associated with corporate and operations support activities. Unrealized gains or losses on crude oil derivative instruments, certain impairments, gains or losses on dispositions or other items that affect comparability (as determined by the CODM) also are not allocated to operating segments.

As discussed in Note 5, we sold our Angola assets in the first quarter of 2014 and our Norway business on October 15, 2014. The Angola and Norway businesses are reflected as discontinued operations and are excluded from the International E&P segment in all periods presented.

^(a)     Settlements are recognized as they occur, once it is probable that lump sum payments from a plan for a given year will exceed the plan's total service and interest cost for that year.

During the first nine months of 2014 and 2013, we recorded the effects of partial settlements of our U.S. pension plans and we remeasured the plans’ assets and liabilities as of the applicable balance sheet dates. As a result, we recognized a pretax increase of $10 million and a pretax decrease of $22 million in actuarial losses in other comprehensive income for the third quarter and first nine months of 2014 and a pretax decrease of $24 million and $163 million in actuarial losses in other comprehensive income for the third quarter and first nine months of 2013.

During the first nine months of 2014, we made contributions of $94 million to our funded pension plans.  We expect to make additional contributions up to an estimated $24 million to our funded pension plans over the remainder of 2014.  Current benefit payments related to unfunded pension plans were $83 million, and payments related to other postretirement benefit plans were $11 million during the first nine months of 2014.

Derivatives

For further information regarding the fair value measurement of derivative instruments, see Note 13. All of our interest rate derivatives are subject to enforceable master netting arrangements or similar agreements under which we may report net amounts. Netting is assessed by counterparty, and as of September 30, 2014 and December 31, 2013, there were no offsetting amounts. Positions by contract were all either assets or liabilities.

The following tables present the gross fair values of derivative instruments, excluding cash collateral, and the reported net amounts along with where they appear on the consolidated balance sheets as of September 30, 2014 and December 31, 2013.

Derivatives Designated as Fair Value Hedges

The following table presents, by maturity date, information about our interest rate swap agreements as of September 30, 2014 and December 31, 2013, including the weighted average, London Interbank Offer Rate (“LIBOR”)-based, floating rate.

As of September 30, 2014 and December 31, 2013, our foreign currency forwards had an aggregate notional amount of 2,246 million and 2,387 million Norwegian Kroner at weighted average forward rates of 6.149 and 6.060. These forwards hedge the current Norwegian tax liability of the subsidiary that holds our Norway business. Those outstanding at September 30, 2014 have settlement dates through February 2015 and were transfered to the purchaser of our Norway business upon closing of the sale on October 15, 2014.

The pretax effects of derivative instruments designated as hedges of fair value in our consolidated statements of income are summarized in the table below. There is no ineffectiveness related to the fair value hedges.
