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 SEC and do not include all of the information and disclosures required by U.S. GAAP for complete financial statements.
AsA reclassification between operating cash flow categories was made to the prior year's financial information to present it on a result ofbasis comparable with the sale of our Angola assets and our Norway business in 2014, both are reflected as discontinued operations. The disclosures in this report related to results of operations andcurrent year's presentation with no impact on net cash flows are presented on the basis of continuing operations, unless otherwise noted.provided by operating activities.
These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 20142015 Annual Report on Form 10-K.  The results of operations for the thirdsecond quarter and first ninesix months of 20152016 are not necessarily indicative of the results to be expected for the full year.
2.   Accounting Standards
Not Yet Adopted
In June 2016, the FASB issued a new accounting standards update that changes the impairment model for trade receivables, net investments in leases, debt securities, loans and certain other instruments. The standard requires the use of a forward-looking "expected loss" model as opposed to the current "incurred loss" model. This standard is effective for us in the first quarter of 2020 and will be adopted on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the adoption period. Early adoption is permitted starting January 2019. 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 March 2016, the FASB issued a new accounting standards update that changes several aspects of accounting for share-based payment transactions, including a requirement to recognize all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This standard is effective for us in the first quarter of 2017 and varying transition methods (modified retrospective, retrospective or prospective) should be applied to different provisions of the standard. Early adoption is permitted. We continue to evaluate the provisions of this accounting standards update but do not believe it will have a material effect on our consolidated results of operations, financial position or cash flows.
In February 2016, the FASB issued a new lease accounting standard, which requires lessees to recognize most leases, including operating leases, on the balance sheet as a right of use asset and lease liability. Short-term leases can continue being accounted for off balance sheet based on a policy election. This standard is effective for us in the first quarter of 2019 and should be applied using a modified retrospective approach at the beginning of the earliest period presented in the financial statements. Early adoption is permitted. We are evaluating the provisions of this accounting standards update and assessing the impact it will have on our consolidated results of operations, financial position or cash flows.
In January 2016, the FASB issued an accounting standards update that addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This standard is effective for us in the first quarter of 2018. Early adoption is allowed for certain provisions. 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 July 2015, the FASB issued an update that requires an entity to measure inventory at the lower of cost and net realizable value. This excludes inventory measured using LIFO or the retail inventory method. This standard is effective for us in the first quarter of 2017 and will be applied prospectively. 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 August 2014, the 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 U.S. auditing standards.  This standard is effective for us for the annual period ending after December 15, 2016 and for annual periods and interim periods thereafter. 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 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 2018 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. While early adoption is permitted, we plan to adopt in the first quarter of 2018. We continue to evaluate certain provisions of this accounting standards update and are assessing the impact it will have on our consolidated results of operations, financial position or cash flows.
Recently Adopted
In May 2015, the FASB issued an update that removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The amendment also removes certain disclosure requirements regarding all investments that are eligible to be measured using the net asset value per share practical expedient and only requires certain disclosures on those investments for which an entity elects to use the net asset value per share expedient. This standard is effective for us in the first quarter of 2016 and will bewas applied on a retrospective basis. Early adoption is permitted. This standard only modifies disclosure requirements; as such, there will bewas no impact on our consolidated results of operations, financial position or cash flows.
In April 2015, the FASB issued an update that requires debt issuance costs to be presented in the balance sheet as a direct reduction from the associated debt liability. This standard is effective for us in the first quarter of 2016 and will be applied on a retrospective basis. 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 February 2015, the FASB issued an amendment to the guidance for determining whether an entity is a variable interest entity ("VIE"). The standard does not add or remove any of the five characteristics that determine ifwhether an entity is a VIE. However, it does change the manner byin which a reporting entity assesses whetherone of the characteristics. In particular, when decision-making over the entity’s most significant activities has been outsourced, the standard changes how a reporting entity assesses if the equity holders at risk lack decision making rights if the decision-making over the subject entity’s most significant activities was outsourced.rights. This standard is effective for us in the first quarter of 2016 and early adoption is permitted. We do not expect the2016. The adoption of this standard todid not have a significant impact on our consolidated results of operations, financial position or cash flows.
In August 2014, the 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 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 2018 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 permitted with an effective date no earlier than first quarter of 2017. 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.

Recently Adopted
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. Expanded disclosures about the assets, liabilities, income and expenses of discontinued operations are 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 were effective for us in the first quarter of 2015 and apply to dispositions or classifications as held for sale thereafter. Adoption of this standard did not impact our consolidated results of operations, financial position or cash flows.

The owners of the Athabasca Oil Sands Project, in which we hold a 20% 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, Alberta, Canada.  Costs under this contract are accrued and recorded on a monthly basis, with current liabilities of $2 million recorded at SeptemberJune 30, 20152016 and $3 million at December 31, 2014.2015.  This contract qualifies as a variable interest contractual arrangement, and the Corridor Pipeline qualifies as a VIE.  We hold a variable interest but are not the primary beneficiary because our shipments are only 20% 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 $471$468 million as of SeptemberJune 30, 2015.2016.  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.

7.    Segment Information
  We are a global energy company with operations in North America, Europe and Africa.have three reportable operating segments. Each of our three reportable operatingthese segments is organized and managed based upon both geographic location and the nature of the products and services it offers.
N.A. E&P – explores for, produces and markets crude oil and condensate, NGLs and natural gas in North America;
Int'l E&P – explores for, produces and markets crude oil and condensate, NGLs and natural gas outside of North America and produces and markets products manufactured from natural gas, such as LNG and methanol, in E.G.; 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 excludingwhich excludes certain items not allocated to segments, net of income taxes, attributable to the operating segments. OurA portion of our corporate and operations support general and administrative costs are not allocated to the operating segments. These unallocated costs primarily consist of employment costs (including pension effects), professional services, facilities and other costs associated with corporate and operations support activities. GainsAdditionally, items which affect comparability such as: gains or losses on dispositions, certain impairments, change in tax expense associated with a tax rate change, unrealized gains or losses on crude oilcommodity derivative instruments, pension settlement losses or other items that affect comparability also(as determined by the CODM) are not allocated to operating segments.
As discussed in Note 6, as a result of the sale of our Angola assets and our Norway business in 2014, both are reflected as discontinued operations and excluded from the Int'l E&P segment for 2014.

During the first ninesix months of 2015, we recorded the effects of a workforce reduction, a U.S. pension plan amendment and the discontinuation of accruals for future benefits under the U.K. pension plan. The U.S. pension plan amendment freezes the final average pay used to calculate the benefit under the legacy final average pay formula and was effective July 6, 2015. For the U.K. pension plan, a final decision was reached with the plan trustees to close the plan to future benefit accruals effective December 31, 2015. Additionally, during the first nine months of 2015 and 2014,2016, we recorded the effects of settlements of our U.S. pension plans. As required, we remeasured the plans' assets and liabilities as of the applicable balance sheet dates. The cumulative effects of these events are included in the remeasurement and reflected in both the pension liability and net periodic benefit cost.
During the first ninesix months of 2015,2016, we made contributions of $65$30 million to our funded pension plans.  We expect to make additional contributions up to an estimated $18$34 million to our funded pension plans over the remainder of 2015.2016.  During the first ninesix months of 2015,2016, we made payments of $57$37 million and $13$10 million related to unfunded pension plans and other postretirement benefit plans, respectively.
9.    Income Taxes
Effective Tax Rate
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 (benefit) 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 ninesix months of 2016 and 2015 were 37% and 2014 were 28% and 32%18%.  The tax provision (benefit) applicable to Libyan ordinary income (loss) was recorded as a discrete item in the first nine months of 2015 and 2014.  Excluding Libya, the effective tax rates on continuing operations, would be 27% and 32% for the first nine months of 2015 and 2014.  In Libya, considerable uncertainty remains around the timing of future production and sales levels. Reliable estimates of 20152016 and 20142015 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, forthe tax benefit applicable to Libyan ordinary loss was

MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)


recorded as a discrete item in the first ninesix months of 20152016 and 2014,2015.  For the first six months of 2016 and 2015, estimated annual effective tax rates were calculated excluding Libya and applied to consolidated ordinary income (loss).
Change Excluding Libya, the effective tax rates would be 36% and 15% for the first six months of 2016 and 2015. The change was driven by a shift in Tax Law
Onjurisdictional income and tax legislation enacted by the Alberta government on June 29, 2015 the Alberta government enacted legislation to increase the provincial corporate tax rate from 10% to 12%.  As a result of this legislation, we recorded additional non-cash deferred tax expense of $135 million in the second quarter of 2015.
Indefinite Reinvestment Assertion
In the second quarter of 2015, we reviewed our operations and concluded that we do not have the same level of capital needs outside the U.S. as previously expected. Therefore, we no longer intend for previously unremitted foreign earnings of

12


MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)


approximately $1 billion associated with our Canadian operations to be permanently reinvested outside the U.S. As such, none of Marathon Oil’s foreign earnings remain permanently reinvested abroad. We anticipate foreign tax credits associated with these Canadian earnings would be sufficient to offset any incremental U.S. tax liabilities, and therefore, no additional net deferred taxes were recorded in the second quarter of 2015.
Deferred Tax Assets
In connection with our assessment of the realizability of our deferred tax assets, we consider whether it is more likely than not that some portion or all of our deferred tax assets will not be realized.  In the event it is more likely than not that some portion or all of our deferred taxes will not be realized, such assets are reduced by a valuation allowance. Future increases to our valuation allowance are possible if our estimates and assumptions (particularly as they relate to downward revisions of our long-term commodity price forecast) are revised such that they reduce estimates of future taxable income during the carryforward period.

These instruments are measured at fair value using either the Black-Scholes Model or the Black Model. Inputs to both models include commodity prices, interest rates, and implied volatility. The inputs to these models are categorized as Level 2 because predominantly all assumptions and inputs are observable in active markets throughout the term of the instruments.
Interest rate swaps are measured at fair value with a market approach using actionable broker quotes, which are Level 2 inputs. See Note 1614 for additional discussion of the types of derivative instruments we use.

Commodity prices began declining in the second half of 2014 and remain substantially lower through 2015. The prolonged decline in commodity prices, and the resulting change in management's future commodity price assumptions, was a triggering event which required us to reassess long-lived assets related to oil and gas producing properties for impairment as of September 30, 2015. Further changes in management's forecast assumptions may cause us to reassess our long-lived assets for impairment, and could result in non-cash impairment charges in the future. Long-lived assets held for use that were impaired are discussed below. 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, unless otherwise noted.  Inputs to the fair value measurement include reserve and production estimates made by our reservoir engineers, estimated future commodity prices

2015 - North America E&P
In the third quarter of 2015, impairments of $333 million were recorded primarily related to certain producing assets in Colorado and the Gulf of Mexico as a result of lower forecasted commodity prices, to an aggregate fair value of $41 million.
    During the second quarter of 2015, we recorded a non-cash impairment charge of $44 million related to our East Texas, North Louisiana and Wilburton, Oklahoma natural gas assets as a result of the anticipated sale (see Note 6). The fair values were measured using a probability weighted income approach based on both the anticipated sales price and a held-for-use model.
2015 - International E&P
In the third quarter of 2015, a partial impairment of $12 million was recorded to an investment in an equity method investee as a result of lower forecasted commodity prices, to a fair value of $604 million. This impairment was reflected in income from equity method investments in our consolidated statements of income.
2014 - North America E&P
The Ozona development in the Gulf of Mexico ceased producing in 2013, at which time those long-lived assets were fully impaired. In the first nine months of 2014, we recorded additional impairments of $30 million 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. In addition, two additional on-shore fields were impaired a total of $47 million to an aggregate fair value of $24 million primarily due to lower forecasted commodity prices.
Fair Values – Goodwill
Unlike long-lived assets, goodwill must be tested for impairment at least annually, or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Goodwill is tested for impairment at the reporting unit level. After weWe estimate the fair value of our International E&P reporting unit using a combination of market and income approaches. The market approach referenced observable inputs specific to us and our industry, such as the price of our common equity, our enterprise value, and valuation multiples of us and our peers from the investor analyst community. The income approach utilized discounted cash flows, which were based on forecasted assumptions. Key assumptions to the income approach include future liquid hydrocarbon and natural gas pricing, estimated quantities of liquid hydrocarbons and natural gas proved and probable reserves, estimated timing of production, discount rates, future capital requirements and operating expenses and tax rates. The assumptions used in the income approach

MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)


are consistent with those that management uses to make business decisions. These valuations methodologies represent Level 3 fair value measurements. We performed our annual goodwill impairment test in April 2015, a triggering event (downward revision of forecasted commodity price assumptions) required us to reassess our goodwill for impairment as of September 30, 2015. Based on the results of this assessment, we2016 and concluded no impairment was required. TheWhile the fair value of the North America E&P andour International E&P reporting unitsunit exceeded their respectivethe book values by a significant margin. Changes in management's forecastvalue, subsequent commodity price assumptionsand/or common stock declines may cause us to reassess our goodwill for impairment, and could result in non-cash impairment charges in the future.

Inputs to the fair value measurement include reserve and production estimates made by our reservoir engineers, estimated future commodity prices adjusted for quality and location differentials and forecasted operating expenses for the remaining estimated life of the reservoir.
During the second quarter of 2015, we recorded a non-cash impairment charge of $44 million related to East Texas, North Louisiana and Wilburton, Oklahoma natural gas assets as a result of the anticipated sale (See Note 6). The fair values were measured using a probability weighted income approach based on both the anticipated sales price and a held-for-use model.
Fair Values – Financial Instruments
Our current assets and liabilities include financial instruments, the most significant of which are receivables, short-term investments, long-term debt due within one year, and payables. We believe the carrying values of our receivables short-term investments 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 insignificant bad debt expense, which includes an evaluation of counterparty credit risk.

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 and 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.

For further information regarding the fair value measurement of derivative instruments, see Note 15.13. All of our interest rate and commodity derivatives are subject to enforceable master netting arrangements or similar agreements under which we may report net amounts.

The pretax effects of derivative instruments designated as hedges of fair value in our consolidated statements of income are summarized in the table below. The foreign currency forwards were used to hedge the current Norwegian tax liability of our Norway business that was sold in the fourth quarter of 2014. Those instruments outstanding were transferred to the purchaser of the Norway business upon closing of the sale. There is no ineffectiveness related to the fair value hedges.

 Derivatives not Designated as Hedges
During the first nine months of 2015, weWe have entered into multiple crude oil and natural gas derivatives indexed to New York Mercantile Exchange ("NYMEX")NYMEX WTI and Henry Hub related to a portion of our forecasted North America E&P sales through December 2016.2017. These commodity derivatives consist of three-way collars, extendable three-waytwo-way collars, call options and call options. Three way-collarsswaptions. Three-way collars consist of a sold call (ceiling), a purchased put (floor) and a sold put. The ceiling price is the maximum we will receive for the contract crude oil volumes, the floor is the minimum price we will receive, unless the market price falls below the sold put strike price. In this case, we receive the NYMEX WTIWTI/Henry Hub price plus the difference between the floor and the sold put price. These commodity derivatives were not designated as hedgeshedges. The following table sets forth outstanding derivative contracts as of June 30, 2016 and are shown in the table below:weighted average prices for those contracts:

  We are a defendant in a number of lawsuitslegal and administrative proceedings arising in the ordinary course of business, including, but not limited to, royalty claims, contract claims, tax disputes 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.  
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.
21.   Subsequent Event
During the third quarter 2016, we executed an agreement to terminate our Gulf of Mexico deepwater drilling rig contract. As a result, we expect to recognize a termination payment of $113 million in other operating expense in that quarter.

Maintained focus on cost discipline and efficiencies
Reduced third quarter cash capital expenditures to $628 million, a 28% decrease compared to the previous quarter, reflecting continued capital discipline and benefits from operating efficiencies

Major Project updates
Alba B3 compression project in E.G., designed to maintain the production plateau two additional years and extend field life up to eight years, was completed within budget and on schedule with first gas in July
Outside-operated Gunflint development project in the Gulf of Mexico achieved first oil in July
Financial results
Cash provided by operating activities of $252 million for the first six months of 2016, despite average crude oil and condensate price realizations of $35.27 per bbl.
Net loss per share of $0.20 in the second quarter of 2016 as compared to net loss per share of $0.57 in the same period last year. Included in the second quarter 2016 net loss are:
Closed on the sale ofUnrealized losses from our East Texas, North Louisiana and Wilburton, Oklahoma natural gas assets in August 2015 for proceeds of approximately $100commodity derivative instruments totaling $91 million,

Financial results
Loss from continuing operations per diluted share of $1.11 in the third quarter of 2015 as compared to income from continuing operations of $0.45 per diluted share in the same period last yearnon-core assets totaling $294 million, pre-tax
Included in the loss for the third quarter are $611Non-cash impairments totaling $141 million, ($949 million pre-tax)pre-tax, as a result of non-cash charges comprised largelyour decision not to drill any of losses and asset impairments resulting from lower forecasted commodity prices and changes in our conventional exploration strategy (refer to Exploration Update below)
Operating cash flow provided by continuing operations for the first nine monthsremaining Gulf of 2015 was $1.2 billion, compared to $3.5 billion in the same period last year, reflecting the lower commodity price environmentMexico leases

Subsequent to the end of the third quarter, we reduced our quarterly dividend from $0.21 to $0.05 per share to address the uncertainty of a lower for longer commodity price environment, to align with our priority of maintaining a strong balance sheet through the cycle and to provide us with additional capital flexibility to support growth from the U.S. resource plays when commodity prices improve.

Outlook
Commodity prices are the most significant factor impacting our revenues, profitability, operating cash flows and the amount of capital available to reinvest into our business. Commodity prices began declining inOur focus continues on the strengthening of the balance sheet, the simplification and concentration of our portfolio and cost reductions which during the second halfquarter of 2014 and remain substantially lower through 2015. We believe we can manage in this lower commodity price cycle through2016 included a continued focus on development inreduction to our three U.S. resource plays, operational execution, efficiency improvements, cost reductions, capital discipline and portfolio optimization, all while maintaining financial flexibility.Capital Program of $100 million to $1.3 billion for the year.
We expect our full-year 2015 capital, investment and exploration budget to be $3.1 billion. We estimate our full-year North America E&P and International E&P production volumes (excluding Libya) to be 380 - 390 net mboed and OSM's synthetic crude oil production to be 40 - 45 net mboed. In addition, based on our current outlook and preliminary plan discussions, we would anticipate a 2016 capital, investment and exploration program of up to $2.2 billion which would give us the flexibility to deliver 2016 annual average production in the U.S. resource plays flat to the 2015 exit rate.
Exploration Update
In September 2015, we announced our intention to scale back our conventional exploration program, with an anticipated 2016 program of approximately $100 million, a reduction of 60% as compared to the 2015 budget, subject to approval byfuture exploration investment focused on fulfilling our Board of Directors.  Our conventional exploration focus will be redirected to existing commitments in the Gulf of Mexico and Gabon.  In second quarter of 2016, we made the decision to not drill our remaining Gulf of Mexico undeveloped leases. As a result, we recorded a non-cash impairments related to unproved propertiesimpairment of $141 million in the second quarter of 2016. Additionally, during the third quarter 2016, we executed an agreement to terminate our Gulf of Mexico and the Harir blockdeepwater drilling rig contract. As a result, we expect to recognize a termination payment of $113 million in the Kurdistan Region of Iraqother operating expense in the thirdthat quarter.

Eagle Ford – Of the 5730 gross operated wells brought to sales during thisthe second quarter 11of 2016, 19 were in the Austin Chalk, 6Lower Eagle Ford, 3 were in the Upper Eagle Ford and 40 in the Lower Eagle Ford.8 were Austin Chalk. Production decreases were due to lower completion activity with fewer gross operated wells brought to sales and reduced contribution from 2015 high-density pads drilled at tighter well spacing. Our average time to drill an Eagle Ford well in the thirdsecond quarter 2015,2016, spud-to-total depth, decreased to 10 days.was 8 days, a decrease from 11 days in the same quarter last year as efficiency gains in drilling continued. Wells were drilled at an average rate of 2,400 feet per day.
Oklahoma Resource BasinsDuringOf the third quarter, we spud our first Springer well and brought online 85 gross operated wells (6 in SCOOP and 2 in STACK), with one of the SCOOP wells being an extended-reach lateral. In addition to the 8 wells mentioned above, we completed an additional Smith infill pilot well in the SCOOP which was brought to sales on October 1. These wells are all in the very early stages of production. We continue to leverage the benefit of participation in outside-operated wells and plan to participate in approximately 55-70 gross outside-operated wells in 2015 in the SCOOP Woodford, SCOOP Springer and STACK areas, with 17 outside-operated wells brought to sales in the second quarter of 2016, 3 were in the SCOOP Woodford; 2 were in the STACK Meramec and all were extended laterals. We also participated in 16 outside-operated wells during the quarter.second quarter of 2016, 10 of which were in the SCOOP and 6 were in the STACK.
We closed on the Payrock acquisition in the STACK play in Oklahoma on August 1, 2016 and continue to operate one drilling rig on the acreage with plans to add another rig late in the third quarter. This will bring the total rig count in Oklahoma to 4.
Bakken – The 5Of the 4 gross operated wells brought to sales thisin the second quarter of 2016, 2 were in the East Myrmidon area. DespiteMiddle Bakken formation and 2 in the lower number of wells to sales this quarter, sales volumes were driven by continued strong performance fromThree Forks formation, all with higher intensity completions. We do not currently have an active drilling rig in the Doll pad wells (West Myrmidon) which came online in late June as well as sustained improvement in production uptime. We expect reduced completions activity during the fourth quarter.Bakken.
Other North America – Net sales volumes declined in the second quarter of 2016 primarily due to the 2015 sales of the non-core assets in the Gulf of Mexico, East Texas, North Louisiana and Wilburton, Oklahoma. On June 30, we closed the sale of certain of our Wyoming upstream and midstream assets. Net sales volumes for all of our Wyoming assets were approximately 16 mboed for the second quarter and first half of 2016. – Development work continues in the

Three months ended June 30, 2016 includes a net sales volume reduction of 17 mboed related to dispositions in the Gulf of Mexico and other conventional onshore U.S. production.
Marketing revenues decreased $470$94 million in the thirdsecond quarter of 20152016 from the comparable prior-year period. 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. The decreases are related primarily to lower marketed volumes in North America E&P and OSM, which were further compounded by a lower commodity price environment.
Income from equity method investments decreased $53increased $11 million in the thirdsecond quarter of 20152016 from the comparable 20142015 period. The decreaseincrease is primarily due to an increase in net sales volumes as 2015 volumes were lower price realizations for LPGbecause of planned turnaround and maintenance activities at ourthe Alba plant,field and E.G. LNG at our LNG facility, and lower methanol prices at our AMPCO methanol facility, allfacilities.

See Note 6 to the consolidated financial statements for information about dispositions.
Production expenses decreased $187$100 million. North America E&P declined $54$50 million primarily due to lower operational, maintenance and labor costs.costs, coupled with the disposition of our producing assets in the Gulf of Mexico and East Texas, North Louisiana and Wilburton, Oklahoma gas assets.

Also contributingfield; these declines were lower productionpartially offset by increased costs in Libya during 2015 as the third quarter of 2014 had one lifting.resulting from higher net sales volumes. OSM


decreased $86$42 million primarily due to lower turnaround costs andcontinued cost management, especiallyspecifically staffing and contract labor. Also contributing to the OSM decrease was a more favorable exchange rate on expenses denominated in the Canadian Dollar and lower feedstock purchases given increased reliability.

Marketing costs decreased $470$94 million in the thirdsecond quarter of 20152016 from the comparable 20142015 period, consistent with the marketing revenues changes discussed above.
 Exploration expenses increased $489 million. We made a strategic decision to reduce the overall level of our conventional exploration program;$78 million primarily as a result we impaired certain of our leases in thedecision to not drill any of our remaining Gulf of Mexico and the Harir block in the Kurdistan Region of Iraq. Further contributing to the increase was an impairment of unproved property in Colorado, which we deemed uneconomic given our forecasted natural gas prices.undeveloped leases.

Depreciation, depletion and amortization (“DD&A”) decreased $20$190 million primarily as a result of production volume decreases, a higher proved reserve base in Eagle Ford the effects of which more than offset additional DD&A resulting from production volume increases in the International E&Psecond half of 2015 and OSM segments.as a result of the non-core asset dispositions in 2015. Our segments apply the units-of-production method to the majority of their assets, including capitalized asset retirement costs; therefore, proved reserve and production volumes have an impact on DD&A expense.
The DD&A rate (expense per boe), which is impacted by field-level changes in sales volumes, proved reserves, and capitalized costs, and sales volume mix by field, can also cause changes to our DD&A. The following table provides DD&A rates for each segment. The DD&A rate for North America E&P decreased primarily as a result of a higher proved reserve base in Eagle Ford.Ford in the second half of 2015. The DD&A rate for International E&P rate increased primarilydeclined due to lower asset retirement costs, with cost estimates refined in the fourth quarter of 2015.

Taxes other than income include production, severance, and ad valorem taxes, primarily in the U.S., which tend to increase or decrease in relation to revenue and sales volumes. With the decrease in North America E&P revenues due to lower price realizations, taxes other than incomevolumes, decreased $69$39 million in the thirdsecond quarter of 2015. This decrease was partially offset by an increase in sales volumes in North America E&P.2016. The following table summarizes the components of taxes other than income:

(a)     Six months ended June 30, 2016 includes a net sales volume reduction of 17 mboed related to dispositions in the Gulf of Mexico and other conventional onshore U.S. production.
Marketing revenues for the first six months of 2016 decreased $1,242by $240 million. 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. SinceBecause the volume of marketing activity is based on market dynamics, it can fluctuate from period to period. The decreases aredecrease is related primarily to lower marketed volumes in North America, which were further compounded by a lower commodity price environment.
Income from equity method investments decreased $248 million$11 million. The decrease is primarily due to lower net sales volumes as a result of planned downtime at E.G. as a result of the Alba field compression project which impacted our equity method plants, which was partially offset by planned turnaround and maintenance activities at the Alba field and E.G. LNG facilities in 2015. Also impacting the first six months of 2016 were lower price realizations for LPG at our Alba Plant, LNG at our LNG facility and lower methanol prices at our AMPCO methanol facility, allplant.


Net gain on disposal of which are located in E.G. Also contributingassets for the first six months of 2016 was primarily related to the decrease in 2015 were lower sales volumes duesale of our Wyoming upstream and midstream assets and West Texas acreage.

Production expenses for the first ninesix months of 20152016 decreased by $397 million.$216 million compared to the same period of 2015. North America E&P declined $101$118 million due to lower operational, maintenance and labor costs.costs, coupled with the disposition of our producing assets in the Gulf of Mexico and East Texas, North Louisiana and Wilburton, Oklahoma gas assets. International E&P declined $115$22 million largely due to lower project work, repair, maintenance and turnaroundoperational costs as well as slightly lower production volumes.in the U.K. OSM declined $181decreased $76 million primarily due to continued cost management, especiallyspecifically staffing and contract labor. Also contributing to the OSM decrease arelabor, lower feedstock purchases given increased reliabilityturnaround costs, and a more favorable exchange rate on expenses denominated in the Canadian Dollar.

Critical Accounting Estimates 
There have been no material changes or developments in the evaluation of the accounting estimates and the underlying assumptions or methodologies pertaining to our Critical Accounting Estimates disclosed in our Form 10-K for the year ended December 31, 2014,2015, except as discussed below.
Fair Value Estimates - Impairment Assessments of Long-Lived Assets and Goodwill
The continued decline of commodity prices resulted in a downward revision of our long-term commodity price assumptions and was a triggering event which required us to reassess long-lived assets related to oil and gas producing properties for impairment as of September 30, 2015. We estimated the fair values using an income approach and concluded that impairments of $337 million were required (See Notes 14 & 15 ). Changes in management's forecast assumptions may cause us to reassess our long-lived assets for impairment, and could result in non-cash impairment charges in the future.
Unlike long-lived assets, goodwillGoodwill must be tested for impairment at least annually, or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Goodwill is tested for impairment at the reporting unit level. After weWe performed our annual goodwill impairment test in April 2015, a triggering event (downward revision to forecasted commodity price assumptions) required us to reassess our goodwill for impairment as of September 30, 2015. Based on the results of this assessment, we2016 and concluded no impairment was required. TheWhile the fair value of the North America E&P andour International E&P reporting unitsunit exceeded their respective book values by a significant margin. Changes in management's forecastvalue, subsequent commodity price assumptionsand/or common stock declines may cause us to reassess our goodwill for impairment, and could result in non-cash impairment charges in the future.
Income Tax Estimates - Deferred Tax AssetsEstimated Quantities of Net Reserves
In connection with our assessmentOur December 31, 2015 proved reserves were calculated using the unweighted average of closing benchmark prices nearest to the realizabilityfirst day of each month within the 12-month period ("SEC pricing"). The table below provides the 2015 SEC pricing for certain benchmark prices as well as the unweighted average for the first eight months of 2016:
 Unweighted 8-month 2016 AverageUnweighted 12-month 2015 Average
WTI Crude oil$40.48$50.28
Henry Hub natural gas2.242.59
Brent crude oil41.0854.25
Natural gas liquids14.9217.32
Any significant future price change could have a material effect on the quantity and present value of our deferred tax assets, we consider whether it is more likely than notproved reserves. To the extent that somecommodity prices decrease during the remainder of 2016, a portion or all of our deferred tax assetsproved reserves could be deemed uneconomic and no longer classified as proved. This could impact both proved developed producing reserves as well as proved undeveloped reserves. Assuming lower commodity pricing in the remaining 4-months of 2016, a material volume of our proved reserves could become uneconomic and would have to be reclassified to non-proved reserve or resource category. In this scenario, our OSM proved reserves represent the largest risk to be reclassified to non-proved reserve or resource category. However, any impact of lower SEC pricing will notlikely be realized.partially offset by continued cost reduction efforts. Also, any volumes reclassified to non-proved reserves could return to proved reserves as commodity prices improve. In the event it is more likely than not that some portionthe OSM proved reserves are reclassified to non-proved reserves or all of our deferred taxesresource, their classification will not be realized, such assets are reduced by a valuation allowance. Future increases to our valuation allowance are possible if our estimates and assumptions (particularly as they relate to downward revisions of our long-term commodity price forecast) are revised such that they reduce estimates ofhave no impact on future taxable income during the carryforward period.plans for production.

Commodity prices began decliningCash flows generated from operating activities in the second halffirst six months of 2014 and remain substantially2016 were lower through 2015.as the downturn in the commodity cycle continued. This lowercontinued downward pressure on price trend adversely impacted our cash flows in 2015. Partially offsettingrealizations, coupled with the decline in prices were increasedlower net sales volumes, in the North America E&P and OSM segments. While we are unable to predict future commodity price movements, if this lower price environment continues it would continue to negatively impact our cash flows from operating activitiesactivities. In the first six months of 2016, consolidated average oil and NGL price realizations were down by approximately 27% and consolidated net sales volumes declined by 9% as compared to the previousprior year.

See Liquidity and Capital Resources below for additional information.
Cash flows from discontinued operations are primarily related to our Norway business, which we disposed of in the fourth quarter of 2014. Disposal of assets in 2015 pertain to the August 2015 sale of our East Texas, North Louisiana and Wilburton, Oklahoma natural gas assets. Disposals of assets in 2014 primarily reflect the net proceeds from the sales of our Angola assets. Disposition transactions are discussed in further detail in Note 6 to the consolidated financial statements.
In October, 2015, we announced an adjustment to our quarterly dividend. See Capital Requirements below for additional information.
Certain of our short-term investments matured in September 2015. Purchases of short-term investments in 2015 were made from proceeds received from the senior notes issuance in June 2015. The investments consisted of time deposits with maturity dates ranging from September - October 2015.

The proceeds were used to repaystrengthen our $1 billion 0.90% senior notes on November 2, 2015,balance sheet and the remainder for general corporate purposes.purposes, including funding a portion of our Capital Program.
In May 2015,Also in March 2016, we amendedincreased our $2.5$3 billion unsecured Credit Facility to increase the facility size by $500$300 million to a total of $3 billion and extend the maturity date by an additional year such that the Credit Facility now matures in May 2020.  The amendment additionally provides us the ability to request two one-year extensions to the maturity date and an option to increase the commitment amount by up to an additional $500 million, subject to the consent of any increasing lenders.  The sub-facilities for swing-line loans and letters of credit remain unchanged allowing up to an aggregate amount of $100 million and $500 million, respectively.$3.3 billion. Fees on the unused commitment of each lender, as well as the borrowing options under the Credit Facility, remain unchanged.unaffected by the increase.
Our main sources of liquidity are cash and cash equivalents, short-term investments,sales of non-core assets, internally generated cash flow from operations, the issuance of notes,capital market transactions, and our $3$3.3 billion Credit Facility and sales of non-core assets.Facility. Our working capital requirements are supported by these sources and we may alsodraw on our $3.3 billion Credit Facility to meet short-term cash requirements, or issue commercial paper, which is backed bydebt or equity securities through the shelf registration statement discussed below as part of our revolving credit facility. Furthermore, we actively manage ourlonger-term liquidity and capital spending program, including the level and timing of activities associated with our drilling programs.management. 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 for the foreseeable future, including our capital spending programs, dividend payments, defined benefit plan contributions, repayment of debt maturities, and other amounts that may ultimately be paid in connection with contingencies.

Due to decreases in crude oil and U.S. natural gas prices, credit rating agencies reviewed companies in the industry earlier this year, including us. During the first quarter of 2016, our corporate credit rating was downgraded by: Standard & Poor's Ratings Services to BBB- (stable) from BBB (stable); by Fitch Ratings to BBB (negative) from BBB+ (stable); and by Moody's Investor Services, Inc. to Ba1 (negative) from Baa1 (stable). Any further rating downgrades could increase our future cost of financing or limit our ability to access capital, and result in additional collateral requirements. See Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2015 for a discussion of how a further downgrade in our credit ratings could affect us.

The June 23, 2016 referendum by British voters to exit the European Union (“Brexit”) provided uncertainty and potential volatility around European currencies, and resulted in a decline in the value of the British pound, as compared to the U.S. dollar and other currencies. Volatility in exchange rates may continue in the short term as the U.K. negotiates its exit from the European Union. A weaker British pound compared to the U.S. dollar during a reporting period causes local currency results of our U.K. operations to be translated into fewer U.S. dollars. For our U.K. operations a majority of our revenues are tied to global crude oil prices which are denominated in U.S. dollars while a significant portion of our operating and capital costs are denominated in British pounds. In addition, our U.K. operations have an asset retirement obligation, which represents a future cash commitment. In the longer term, any impact from Brexit on our U.K. operations will depend, in part, on the outcome of tariff, trade, regulatory, and other negotiations.

Capital Resources
Credit Arrangements and Borrowings
At SeptemberJune 30, 2015,2016, 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 SeptemberJune 30, 2015,2016, we had $8.4$7.3 billion in long-term debt outstanding, with our next debt maturity in the amount of which approximately $1.0 billion matured and was repaid$682 million due in November 2015. We utilized cash on hand and proceeds from the maturitiesfourth quarter of our short-term investments to fund the debt payment. 2017.
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 Disposals
We are targeting to generate at least $500 million from select non-core asset sales. During the third quarter, of 2015, we closed the sale of our East Texas, North Louisiana and Wilburton, Oklahoma natural gas assets for proceeds of approximately $100 million and announced the sale of our KenyaWyoming upstream and Ethiopia exploration acreage. See Note 6midstream assets for proceeds of $870 million, before closing adjustments, of which approximately $690 million was received in the second quarter.  The remaining asset sales are subject to the consolidated financial statementsreceipt of certain tribal consents and are expected to close before year end. The proceeds for additional discussionthe remaining asset sales were deposited into an escrow account by the buyer.
In March and April 2016, we entered into separate agreements to sell our 10% working interest in the outside-operated Shenandoah discovery in the Gulf of these dispositions.        Mexico, operated natural gas assets in the Piceance basin in Colorado and certain undeveloped acreage in West Texas for a combined total of approximately $80 million in proceeds, before closing adjustments. We closed on certain of the asset sales during the six months ended June 30, 2016. The remaining asset sales are expected to close by year-end.

Capital Requirements
We closed on our purchase agreement of PayRock for $888 million, as discussed in Note 5 to the consolidated financial statements. We expect our revised total capital, investment and exploration spending budgetCapital Program for full-year 20152016 to be $3.1$1.3 billion, or $100 million lower than the original budget, which is $200 million less than our previous budget.includes the increased activity from the PayRock acquisition.
On October 28, 2015,July 27, 2016, our Board of Directors approved a dividend of $0.05 per share for the thirdsecond quarter of 20152016 payable December 10, 2015September 12, 2016 to stockholders of record at the close of business on November 18, 2015. This dividend represents a reduction from the previous quarterly dividend of $0.21 per share as we continue to address the uncertainty of a lower for longer commodity price environment, align with our priority of maintaining a strong balance sheet through the cycle, and provide additional capital flexibility to support growth from the U.S. resource plays when commodity prices improve.August 17, 2016.
As of SeptemberJune 30, 2015,2016, we plan to make contributions of up to $18$34 million to our funded pension plans during the remainder of 2015.2016.

Contractual Cash Obligations
As of SeptemberJune 30, 2015,2016, there are no material changes to our consolidated cash obligations to make future payments under existing contracts, as disclosed in our 20142015 Annual Report on Form 10-K, except for the agreement we entered into to acquire PayRock as described above, which was paid with cash on hand.
During the third quarter we executed an agreement to terminate our issuanceGulf of $2 billion aggregate principal amountMexico deepwater drilling rig contract, as a result we expect to make a termination payment of unsecured senior notes, as more fully described in Note 18.$113 million during the third quarter of 2016.
          
Environmental Matters and Other Contingencies
We have incurred and will continue to incur capital, operating and maintenance, and remediation expenditures asIn July 2015, we received a resultrequest for information from the EPA under Section 114 of environmental laws and regulations.  If these expenditures, as with all costs, are not ultimately reflectedthe Clean Air Act regarding several tank batteries used in our Bakken operations.  Beginning in the pricessecond quarter of 2016, we have been in settlement discussions with the State of North Dakota’s Department of Health regarding potential noncompliance with the Clean Air Act, North Dakota Century Code Air Pollution Control provisions, and implementing regulations. To date, no federal or state enforcement action has been commenced in connection with this matter.  We anticipate that resolution of this matter will result in civil or administrative penalties of an undetermined amount and require us to undertake corrective actions which may increase our products and services, ourdevelopment and/or operating results will be adversely affected.costs.  We do not believe that substantially all of our competitors must comply with similar environmental laws and regulations.  However, the specific impact on each competitorany penalties or corrective action expenditures that 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, 2014.
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 proceedingsresult from this matter will not have a material adverse effect on our consolidated financial position, results of operationsoperation or cash flows.

Item 5. Other Information
As we previously disclosed in a Form 8-K filed with the SEC on August 28, 2015, our Board of Directors amended and restated our By-laws, effective September 1, 2015, to modify the existing proxy access provisions of the By-laws to coincide with the stockholder proposal that was approved at our 2015 annual meeting of stockholders.
Pursuant to these amendments, the required ownership percentage needed to use the proxy access provisions was decreased to 3% of Marathon Oil’s outstanding common stock, owned continuously for at least three years. Additionally, the maximum number of stockholder nominees that may be included in the proxy statement pursuant to these provisions was increased to 25% of the number of directors in office as of the last day on which notice requesting proxy access may be delivered by an eligible stockholder.
