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 SEC and do not include all of the information and disclosures required by U.S. GAAP for complete financial statements.
A reclassificationThese interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2016 Annual Report on Form 10-K.  The results of operations for the first quarter of 2017 are not necessarily indicative of the results to be expected for the full year.
As a result of the announcement to divest of our Canadian business in the first quarter of 2017, we have reflected this business as discontinued operations in all periods presented. The disclosures in this report related to the 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. This divestiture is discussed in further detail in Note 6.
During the current period, we adopted the accounting standards update issued by the FASB in March 2016 pertaining to share-based payment transactions. See Note 2 for additional discussion. As a result of this adoption all cash payments, for withheld shares, made to taxing authorities on the employees' behalf will be presented within the financing activities section instead of the operating activities section of the statement of cash flows. We have elected the retrospective method for adoption of this update and the change in the statement of cash flows is not material for March 31, 2016. Excess tax benefits will be classified as an operating activity within the statement of cash flows on a prospective basis; as such, prior periods were not adjusted. See Note 2 for additional discussion.
We have reclassified certain prior year amounts between operating cash flow categories was made to the prior year's financial information to present it on a basis comparable with the current year's presentation with no impact on net cash provided by operating activities.
These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2015 Annual Report on Form 10-K.  The results of operations for the second quarter and first six months of 2016 are not necessarily indicative of the results to be expected for the full year.
2.   Accounting Standards
Not Yet Adopted
In March 2017, the FASB issued a new accounting standards update that will change how employers that sponsor defined pension and/ or other postretirement benefit plans present the net periodic benefit cost in the income statement. Employers will present the service cost component of net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. Only the service cost component will be eligible for capitalization in assets. This standard is effective for us in the first quarter of 2018 and shall be applied on a retrospective basis. Early adoption is permitted. We are evaluating the provisions of this accounting standards update and assessing the impact it may have on our results of operations, financial position, or cash flows.
In February 2017, the FASB issued a new accounting standards update that clarifies the accounting for the sale or transfer of nonfinancial assets and in substance nonfinancial assets to noncustomers, including partial sales. The standard also clarifies that the derecognition of all businesses (except those related to conveyances of oil and gas mineral rights or contracts with customers) should be accounted for in accordance with the derecognition and deconsolidation guidance in Subtopic 810-10. This standard is effective for us in the first quarter of 2018 and will be applied using the modified retrospective approach. Early adoption is permitted. We plan to adopt this new standard in the first quarter of 2018 concurrently with the new revenue recognition standard. 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 2017, the FASB issued a new accounting standards update that changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities constitutes a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities would not represent a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are described in the new revenue guidance. This standard is effective for us in the first quarter of 2018 and shall be applied on a prospective basis. Early adoption is permitted for certain transactions as described in the guidance. 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.
MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)



In January 2017, the FASB issued a new accounting standards update that eliminates the requirement to calculate the implied fair value of the goodwill (i.e., Step 2 of goodwill impairment test under the current guidance) to measure a goodwill impairment charge. The standard will require entities to record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on Step 1 under the current guidance). This standard is effective for us in the first quarter of 2020 and shall be applied on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. 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 November 2016, the FASB issued a new accounting standards update that requires entities to show the changes in the total of cash, cash equivalents and restricted cash in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash in the statement of cash flows. When cash, cash equivalents, and restricted cash are presented in more than one line item on the balance sheet, the standard requires a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet. This reconciliation can be presented either on the face of the statement of cash flows or in the notes to the financial statements. This standard is effective for us in the first quarter of 2018 and shall be applied on a retrospective basis. Early adoption is permitted. We are evaluating the provisions of this accounting standards update and assessing the impact it may have on our consolidated statements of cash flows and related disclosures.
In August 2016, the FASB issued a new accounting standards update which seeks to reduce the existing diversity in practice in how certain transactions are classified in the statement of cash flows. This standard is effective for us in the first quarter of 2018 and shall be applied on a retrospective basis. Early adoption is permitted. We are evaluating the provisions of this accounting standards update and assessing the impact, if any, it may have on our consolidated statements of cash flows and related disclosures.
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"“expected loss” model as opposed to the current "incurred loss"“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.

Notes to Consolidated Financial Statements (Unaudited)


In May 2014 and August 2015, 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 shouldshall be applied retrospectively to each prior reporting period presented (“full retrospective method”) or with the cumulative effect of initially applying the update recognized at the date of initial application.application (“modified retrospective method”). While early adoption is permitted, we plan to adopt this new standard in the first quarter of 2018.2018 using the modified retrospective method. We continue to evaluate certain provisions ofassess our contracts that will be subject to this accounting standards updatestandard and are assessingassess the impact it will have on our consolidated results of operations, financial position or cash flows.

Recently Adopted
In May 2015,March 2016, the FASB issued ana new accounting standards update that removes thechanges several aspects of accounting for share-based payment transactions, including a requirement to categorize withinrecognize all excess tax benefits and tax deficiencies as income tax expense or benefit in the fair value hierarchy all investments for which fair value is measured usingincome statement, classification of awards as either equity or liabilities, and classification on 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.statement of cash flows. This standard iswas effective for us in the first quarter of 2016 and was applied2017. The new standard requires a company to make a policy election on a retrospective basis. Thishow it accounts for forfeitures; we elected to continue estimating forfeitures using the same methodology practiced prior to adoption of this standard. See Note 1 for the impact this standard only modifies disclosure requirements; as such, there was no impacthas on the presentation of our consolidated results of operations, financial position or cash flows.statements.
In FebruaryJuly 2015, the FASB issued an amendment to the guidance for determining whetherupdate that requires an entity is a variable interest entity ("VIE"). The standard does not addto measure inventory at the lower of cost and net realizable value. This excludes inventory measured using LIFO or remove any of the five characteristics that determine whether an entity is a VIE. However, it does change the manner in which a reporting entity assesses one 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.retail inventory method. This standard iswas effective for us in the first quarter of 2016. The adoption2017, and was applied prospectively. 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 (AOSP), 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 June 30, 2016March 31, 2017 and December 31, 2015.2016.  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 $468$472 million as of June 30, 2016.March 31, 2017.  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. This contract will be transferred to the purchaser of our Canadian business upon closing in mid-2017. See Note 6 regarding dispositions. The accrued contract costs are reported within current liabilities held for sale.

7.    Segment Information
  We have three2 reportable operating segments. EachBoth of these segments isare 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;America and
Int'lInt’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 (loss) represents income (loss) which excludes certain items not allocated to segments, net of income taxes, attributable to the operating segments. A 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. Additionally, 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 commodity derivative instruments, pension settlement losses or other items (as determined by the CODM) are not allocated to operating segments.
As discussed in Note 6, we entered into an agreement to sell our Canadian business in March 2017. The Canadian business is reflected as discontinued operations and is excluded from segment information in all periods presented.

During the first sixthree months of 2016,2017, we recorded the effects of settlements of our U.S. pension plans. As required, we remeasured the plans'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.

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 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 For the three-month periods in 2017 and 2016, our effective income tax rates on continuing operations was as follows:

We expect to be in a cumulative loss position in 2017, for tax purposes, and 18%.as a result have placed a full valuation allowance on our federal deferred tax assets for the quarter totaling $57 million. During 2017 we expect to realize no tax benefit on any federal deferred tax assets generated. See Deferred Tax Assets section below for further detail.
In the first quarter, we also settled our 2011-2013 Alaska income tax audit. The settlement of the audit resulted in the recognition of a tax benefit totaling $13 million.
The impact of foreign operations for the quarter was primarily related to a tax benefit on currency remeasurement impacts totaling $3 million. The foreign tax expense impacts related to our Libya, E.G. and U.K. operations in the first quarter of 2017 are largely offset by deferred tax benefits being generated in the U.K. associated with tax refunds related to future decommissioning costs. In Libya, considerable uncertainty remains around the timing of future production and sales levels. Reliablereliable estimates of 20162017 and 2015 Libyan2016 annual ordinary income from our Libyan operations could not be made, and the range of possible scenarios in the worldwide annual effective tax rate calculation demonstrates significant variability. Thus, the tax benefitimpacts applicable to Libyan ordinary lossincome (loss) was

Excluding Libya, the effective income tax expense (benefit) rates would be 36%(16)% and 15%(40)% for the first sixthree months of 20162017 and 2015. The change was driven by a shift in jurisdictional income and tax legislation enacted by the Alberta government on June 29, 20152016.

Notes 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.  Consolidated Financial Statements (Unaudited)



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 toThe estimated realizability of the benefit of our valuation allowance are possible if our estimatesdeferred tax asset is assessed considering a preponderance of evidence. This assessment requires analysis of all available positive and assumptions (particularly as they relate to our long-term commodity price forecast) are revised such that they reduce estimatesnegative evidence. Positive evidence includes reversals of temporary differences, forecasts of future taxable income, assessment of future business assumptions and applicable tax planning strategies. Negative evidence includes losses in recent years as well as the forecasts of future income (loss) in the realizable period. We expected to be in a cumulative loss position in 2017, which constitutes significant objective negative evidence as to the future realizability of the value of our federal deferred tax assets. Due to this negative evidence, we placed a full valuation allowance on our federal deferred tax assets during the carryforward period.2016 and expect to realize no tax benefit on any federal deferred tax assets generated in 2017.

10.   Short-term Investments
As of June 30, 2015, we held short-term investments comprised of bank time deposits with original maturities of greater than three months and remaining maturities of less than twelve months.

Our Libya operations continuehave been interrupted in recent years due to be impacted by civil unrest. Operations were interruptedOn September 14, 2016, Force Majeure was lifted and production resumed in mid-2013 as a result of the shutdown of the Es-Sider crude oil terminal, and although temporarily re-opened during the second half of 2014, production remains shut-in. Earlier this year, an Internationally-backed Unity Government was established in Tripoli. During the second quarter, the two National Oil Companies agreed to unify and reportedly have begun preliminary discussions on re-opening the Es-Sider and other crude oil terminals which, if successful, will allow resumption of production operationsOctober 2016 at our Waha concessions. However, considerable uncertainty remains aroundconcession. During December 2016, liftings resumed from the timingEs Sider crude oil terminal.

As of June 30, 2016,March 31, 2017, our net property, plant and equipment investment in Libya is $775$767 million, and total proved reserves (unaudited) in Libya as of December 31, 20152016 are 235206 million barrels of oil equivalent ("mmboe"(“mmboe”). 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. The undiscounted cash flows related to our Libya assets continue to exceed the carrying value of $775$767 million by a materialsignificant amount. However, changes in

Commodity derivatives include three-way collars, two-way collars, call options and swaptions.swaps. These instruments are measured at fair value using either thea Black-Scholes Model or the Blacka modified Black-Scholes Model. Inputs to boththe models include commodity prices, interest rates, and implied volatility. The inputs to these modelsvolatility and are categorized as Level 2 because predominantly all assumptions and inputs are observable in active markets throughout the term of the instruments.
InterestBoth our interest rate swaps and forward starting interest rate swaps are measured at fair value with a market approach using actionable broker quotes, which are Level 2 inputs. See Note 14 for additional discussion of the types of derivative instruments we use.
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. We 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

are consistent with those that management uses to make business decisions. These valuations methodologies represent Level 3 fair value measurements. We performed our annual impairment test in April 2016 and concluded no impairment was required. While the fair value of our International E&P reporting unit exceeded the book value, subsequent commodity price and/or common stock declines may cause us to reassess our goodwill for impairment, and could result in non-cash impairment charges in the future.

Fair Values – Financial Instruments
Our current assets and liabilities include financial instruments, the most significant of which are receivables, long-term debt and payables. We believe the carrying values of our receivables 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 credit rating, and (3) our historical incurrence of and expected future insignificant bad debt expense, which includes an evaluation of counterparty credit risk.

Derivatives Designated as Cash Flow Hedges
During the third quarter of 2016, we entered into forward starting interest rate swaps to hedge the variations in cash flows related to fluctuations in long term interest rates from debt that is probable to be refinanced by us in 2018, specifically interest rate risk associated with future changes in the benchmark treasury rate. The occurrence of the forecasted transaction is probable and each respective derivative contract can be tied to an anticipated underlying dollar notional amount. At conclusion of the hedge in the first quarter of 2018, the final value will be reclassified from accumulated other comprehensive income into earnings. At March 31, 2017, the forward starting interest rate swaps continued to qualify as an effective hedge and the ineffective portion was not significant in the quarter.

These commodity derivatives consist of three-way collars, two-way collars,swaps, and call options and swaptions.options. 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 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 WTI/Henry Hub price plus the difference between the floor and the sold put price. These commodity derivatives were not designated as hedges.

20.   Commitments and Contingencies
  We are a defendant in a number of legal 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.

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. Our focus continues on the strengthening of the balance sheet, the simplification and concentration of our portfolio and cost reductions which during the second quarter of 2016 included a reduction to our Capital Program of $100 million to $1.3 billion for the year.

Exploration Update
In September 2015, we announced our intention to scale back our conventional exploration program, with future exploration investment focused on fulfilling our 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 impairment of $141 million incharge during the secondfirst quarter of 2016. Additionally, 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.2017

Eagle Ford – Of the 30 gross operated wells brought to sales during the second quarter of 2016, 19 were Lower Eagle Ford, 3 were Upper Eagle Ford and 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 second quarter 2016, spud-to-total depth, 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 Basins – Of the 512 gross operated wells brought to sales in the secondfirst quarter of 2016, 3 were in the SCOOP Woodford; 22017, 11 were in the STACK Meramec and all were extended laterals. We also participated in 16 outside-operated wells during the second quarter of 2016, 10 of which wereone well was in the SCOOP and 6 were in the STACK.Woodford. The SCOOP Woodford well that was brought to sales was an extended lateral.
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 – Of the 412 gross operated wells brought to sales in the secondfirst quarter of 2016,2017, five were part of our first operated STACK infill spacing test, the Yost pilot, and the others were focused primarily on STACK lease retention and delineation. The Yost pilot, located in the normally pressured black oil window in central Kingfisher County, successfully tested 107-acre well spacing with completions of approximately 2,500 pounds of proppant per lateral foot during the first quarter of 2017. Rig activity increased from five to seven drilling rigs in the STACK/SCOOP during the first quarter of 2017. We expect to average approximately 10 drilling rigs in 2017.
Eagle Ford – During the first quarter of 2017, we brought 47 gross operated wells to sales, of which 33 were Lower Eagle Ford, 12 were Upper Eagle Ford and 2 were Austin Chalk. We held our activity levels flat from year end 2016 with six rigs drilling in Karnes, Atascosa, Live Oak and Gonzales counties.
During the Middle quarter, wells were drilled at an average rate of 2,500 feet per day and one of our wells achieved a new Company-record at more than 4,000 feet per day. We ended the quarter with six drilling rigs and expect to maintain an average of six drilling rigs in 2017.
Bakken formation and 2– Of the four gross operated wells brought to sales in East Myrmidon during the first quarter of 2017, three were in the Three Forks formation all with higher intensity completions. We do not currently have an active drilling rigand one in the Bakken.Middle Bakken formation. In the first quarter we increased our rig activity from one to seven drilling rigs, and expect to average approximately six drilling rigs in 2017.
Other North America – Net sales volumes declined in the secondfirst quarter of 20162017 primarily due to the 2015 salesdisposition of the non-coreWyoming and certain non-operated assets in West Texas and New Mexico in 2016. See Note 6 to the Gulf of Mexico, East Texas, North Louisiana and Wilburton, Oklahoma. On June 30, we closedconsolidated financial statements for information about dispositions. This decrease was partially offset by 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.
The Gunflint field located in Mississippi Canyon block 948 in the Gulf of Mexico achieved firstwhich began production in Julythe second half of 2016. Full production is expected to reach at least 20 mboed gross with oil representing approximately 75% of the volumes produced. We hold an 18% non-operated working interest in the Gunflint field.


International E&P
Net sales volumes in the segment were higher in the secondfirst quarter of 2017 compared to the first quarter of 2016 due primarily as a resultto the completion and start-up of our E.G. Alba field compression project in mid-2016 and planned turnaround and maintenance activities atwhich occurred during the Alba field and E.G. LNG facilities in the secondfirst quarter of 2015.2016.

United Kingdom – Net sales volumes in the first sixthree months of 2017 were marginally lower compared to the first quarter of 2016 were lower due to repair activitiesas a result of reliability issues at the Brae Alpha facility following a process pipe failure in late 2015.  Production was restored at the facility in late April.  Higher overall production efficiency at the remaining Brae facilities and improved reliability from the outside-operated Foinaven field partially offset the Brae Alpha shut-in.Field.

During the second quarter, the two National Oil Companies agreedMarch 2017 due to unify and reportedly have begun preliminary discussions on re-opening the Es-Sider and other crude oil terminals which, if successful, will allow resumption of production operations at our Waha concessions. However, considerable uncertainty remains around the timing of future production and sales levels.civil unrest.
Discontinued Operations - Oil Sands Mining
In March 2017, we entered into an agreement to sell our Canadian business, including our OSM segment, to Shell and Canadian Natural Resources Limited for $2.5 billion in cash, excluding closing adjustments. We expect to close the sale in mid-2017 with an effective date of January 1, 2017.
The oil sands mining business is excluded from the segment results and is reported as discontinued operations for all periods presented. Our net synthetic crude oil sales volumes were 49 mbbld and 5460 mbbld in the secondfirst quarter and first six months of 20162017 compared to 29 mbbld and 4459 mbbld in the same periods of 2015. Sales volumes increased in comparison to second quarter and first six months of 2015 which were adversely affected due to planned turnarounds at the base upgrader and Muskeg River Mine and unplanned downtime at the expansion upgrader. These sales volume increases were partially offset by a brief suspension of operations at both the Muskeg River and Jackpine mines in May 2016 in order to support emergency response efforts related to the Fort McMurray area wildfires in addition to the completion of planned maintenance activities at the Jackpine Mine and expansion upgrader that began in the first quarter 2016. Neither of the mines sustained any damage as a result of the wildfires. We hold a 20% non-operated working interest in the Athabasca Oil Sands Project.

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 changes in reserves, capitalized costs, and sales volume mix by field, can also cause changes to our DD&A. Our North America E&P DD&A rate increased in the first quarter of 2017 primarily due to the increased rate in the Gulf of Mexico as a result of the Gunflint field achieving first production in mid-2016. The DD&A rate for International E&P increased primarily due to sales volume mix changes between countries in the current quarter and increased U.K. asset retirement costs due to changes in timing and costs of abandonment activities that occurred at year-end 2016. 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 in the second half of 2015. The DD&A rate for International E&P declined due to lower asset retirement costs, with cost estimates refined in the fourth quarter of 2015.

(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 by $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. Because the volume of marketing activity is based on market dynamics, it can fluctuate from period to period. The decrease is related primarily to lower marketed volumes in North America, which were further compounded by a lower commodity price environment.
Income from equity method investmentsdecreased $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, whichmaintenance activities. This was partially offset by planned turnaround and maintenance activities at the Alba field and E.G. LNG facilitiesan increase in 2015. Also impacting the first six months of 2016 were lower price realizations for LPG at our Alba plant.


Net gain on disposal of assets for the first six months of 2016 was primarily related to the sale of our Wyoming upstream and midstream assets and West Texas acreage. See Note 6 to the consolidated financial statements for information about dispositions.
Production expenses for the first six months of 2016 decreased by $216 million compared to the same period of 2015. North America E&P declined $118 million due to lower operational, maintenance and labor 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 $22 million largely due to lower operational costs in the U.K. OSM decreased $76 million primarily due to continued cost management, specifically staffing and contract labor, lower turnaround costs, and a favorable exchange rate on expenses denominated in the Canadian Dollar.
The first six months of 2016 production expense rate (expense per boe) for North America E&P declined primarily due to cost reductions that occurred at a rate faster than our production decline. The International E&P expense rate decreased in the first six months of 2016 primarily due to reduced maintenance and project costs in the U.K. The OSM expense rate decreased in the first six months of 2016 primarily due to higher production coupled with lower operational costs.

Production expense per synthetic crude oil barrel includes production costs, shipping and handling, taxes other than income and insurance costs and excludes pre-development costs.
Marketing costs decreased $241 million in the first six months of 2016 from the comparable 2015 period, consistent with the marketing revenues changes discussed above.
Exploration expenseswere $12 million higher in the first six months of 2016 than in the comparable 2015 period primarily due to higher unproved property impairments, which were partially offset by lower dry well costs. Unproved property impairments were higher in 2016 primarily as a result of Gulf of Mexico leases that we decided not to drill. Dry well costs for the first six months of 2015 primarily consist of costs associated with the Sodalita West #1 well in E.G., the Key Largo well in the Gulf of Mexico, and suspended well costs related to Birchwood in-situ.

Depreciation, depletion and amortization(“DD&A”) decreased $402 million in the first six months of 2016 from the comparable 2015 period primarily as a result of production volume decreases and a higher proved reserve base in Eagle Ford in the second half of 2015. 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 field-level changes in sales volumes, reserves and capitalized costs, 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 in the second half of 2015.

Impairments decreased $43 million in the first six months of 2016 as a result of the second quarter of 2015 non-cash impairment charge related to East Texas, North Louisiana and Wilburton, Oklahoma natural gas assets in anticipation of the sale in 2015. See Note 13 to the consolidated financial statements for discussion of the impairment.
Taxes other than incomeinclude production, severance and ad valorem taxes, primarily in the U.S., which tend to increase or decrease in relation to revenue and sales volumes, decreased $58 million in the first six months of 2016 from the comparable 2015 period.

General and administrative expensesdecreased $56 million in the first six months of 2016 compared to the same period in 2015. This decrease was primarily due to cost savings realized from the 2015 workforce reductions and corresponding severance expenses.
Provision (benefit) for income taxes reflect effective tax rates of 37% in the first six months of 2016, as compared to 18% from the comparable 2015 period. See Note 9 to the consolidated financial statements for discussion of the effective tax rate.
Segment Income(Loss)
Segment income (loss) represents income (loss) 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. Gains or losses on dispositions, certain impairments, change in tax expense associated with a tax rate change, unrealized gains or losses on crude oil derivative instruments, or other items that affect comparability also are not allocated to operating segments.

 North America E&P segment loss increased $59 million after-tax in the first six months of 2016 from the comparable 2015 period primarily due to lower price realizations and sales volumes, which was partially offset by the impact of lower net sales volumes to DD&A, production costs and taxes other than income; and lower exploration expenses.
International E&P segment incomedecreased $5 million after-tax in the first six months of 2016 from the comparable 2015 period primarily due to lower liquid hydrocarbon price realizations. These declines were partially offset by lower exploration, production and DD&A expenses.
Oil Sands Mining segment lossdecreased $10 million after-tax in the first six months of 2016 from the comparable 2015 period primarily due to higher sales volumes and lower production expenses, partially offset by lower price realizations and higher DD&A expense.


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, 2015, except as discussed below.2016.
Fair Value Estimates - Goodwill
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. We performed our annual impairment test in April 2016 and concluded no impairment was required. While the fair value of our International E&P reporting unit exceeded book value, subsequent commodity price and/or common stock declines may cause us to reassess our goodwill for impairment, and could result in non-cash impairment charges in the future.
Estimated Quantities of Net Reserves
Our December 31, 2015 proved reserves were calculated using the unweighted average of closing benchmark prices nearest to the first 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 proved reserves. To the extent that commodity prices decrease during the remainder of 2016, a portion of our proved 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 likely be 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 the OSM proved reserves are reclassified to non-proved reserves or resource, their classification will have no impact on future plans for production.

Cash flows generated from operating activities in the first sixthree months of 20162017 were lowerhigher as commodity prices improved compared to the downturnfirst quarter of 2016. This drove an increase in price realizations in the commodity cycle continued. This continued downward pressure onfirst three months of 2017. Consolidated average liquid hydrocarbon price realizations coupled with the lower net sales volumes, continues to negatively impact our cash flows from operating activities. Inincreased by more than 65% during the first six monthsquarter of 2016, consolidated average oil and NGL price realizations were down by approximately 27% and consolidated net sales volumes declined by 9%2017 as compared to the prior year.period. This increase in price realization coupled with our continued focus on cost reduction, including production expense and general & administrative expense, resulted in our increased cash flows generated from operating activities.
Proceeds from disposals of assets are primarily from the sale of our Wyoming upstream and midstream assets; see Note 6 to the consolidated financial statements for further information concerning dispositions. Common stock issuance reflects net proceeds received in March 2016 from our public sale of common stock. See Liquidity and Capital Resources belowNote 18 to the consolidated financial statements for additional information.

The Board of Directors approved a $0.05 per share dividend for the first quarter of 2016, which was paid in the second quarter of 2016. See Capital Requirements below for additional information about the second quarter dividend.


Liquidity and Capital Resources
In March 2016, we issued 166,750,000 shares of our common stock, par value $1 per share, at a price of $7.65 per share, excluding underwriting discounts and commissions, for net proceeds of $1,236 million. The proceeds were used to strengthen our balance sheet and for general corporate purposes, including funding a portion of our Capital Program.
Also in March 2016, we increased our $3 billion unsecured Credit Facility by $300 million to a total of $3.3 billion. Fees on the unused commitment of each lender, as well as the borrowing options under the Credit Facility, remain unaffected by the increase.
Our main sources of liquidity are cash and cash equivalents, sales of non-core assets, internally generated cash flow from operations, sales of non-core assets, capital market transactions, and our $3.3 billion Credit Facility.revolving credit facility. At March 31, 2017, we had approximately $5.8 billion of liquidity consisting of $2.5 billion in cash and cash equivalents and $3.3 billion available under our revolving credit facility. Our working capital requirements are supported by these sources and we may draw on our $3.3 billion Credit Facilityrevolving credit facility to meet short-term cash requirements, or issue debt or equity securities through the shelf registration statement discussed below as part of our longer-term liquidity and capital management. Because of the alternatives available to us as discussed above, we believe that our short-term and long-term liquidity isare 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, and other amounts that may ultimately be paid in connection with contingencies.
DueGeneral economic conditions, commodity prices, and financial, business and other factors could affect our operations and our ability to decreases in crude oil and U.S. natural gas prices, credit rating agencies reviewed companies inaccess the industry earlier this year, including us. During the first quarter of 2016, ourcapital markets. Our corporate credit rating was downgraded by:ratings as of March 31, 2017 are: 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 downgradesA downgrade in our credit ratings 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, 20152016 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 June 30, 2016,March 31, 2017, we had no borrowings against our revolving credit facility.
At June 30, 2016,March 31, 2017, we had $7.3 billion in long-term debt outstanding, with ouroutstanding. Our next debt maturity in the amount of $682 million is due in the fourth quarter of 2017.2017 and $854 million is due in the first quarter of 2018.
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 equitydebt and debtequity securities. 
Pending Asset DisposalsDisposal
DuringIn March 2017, we entered into an agreement to sell our Canadian business for $2.5 billion. Under the quarter, we announcedterms of the sale of our Wyoming upstream and midstream assets for proceeds of $870 million, beforeagreement, $1.75 billion, subject to closing adjustments, of which approximately $690 million was receivedwill be paid to us upon closing and the remaining proceeds will be paid in the second quarter.first quarter of 2018.

We paid $180 million in aggregate deposits into escrow related to these acquisitions during the first quarter of 2017. We closed on certain of the asset sales during the six months ended June 30, 2016. The remaining asset sales are expectedacquisition from BC Operating, Inc. and other entities with cash on hand on May 1, 2017 and expect to close by year-end.our remaining acquisition from Black Mountain Oil & Gas and other private sellers in the second quarter of 2017 with cash on hand.

Environmental Matters and Other Contingencies
In July 2015, we received a request for information from the EPA under Section 114 of the Clean Air Act regarding several tank batteries used in our Bakken operations.  BeginningWe executed a settlement agreement with the North Dakota Department of Health relating to this matter in the secondfourth quarter of 2016 we have been in settlement discussions withthat includes a base penalty of $294,000 that will be reduced under 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 undertaketerms by mitigating corrective actions which may increase our development and/or operating costs.actions.  We do not believe that any penalties or corrective action expenditures that may result from this matter will have a material adverse effect on our financial position, results of operation or cash flows. 
In March 2016 we proactively notified the U.K. environmental regulator Business, Energy and Industrial Strategy (“BEIS”) that we had recognized an error in our carbon dioxide (“CO2”) emissions reporting.  In December 2016 we received a


‘Notice of Intent to Impose a Civil Penalty’ from BEIS for the self-disclosed underreporting of CO2 emissions.  The letter advised that the penalty for this event had initially been set at €946,360, however BEIS had reduced the amount to €630,906 in recognition of our self-reporting and proactive cooperation with the investigation. In February 2017 we received the final letter from BEIS, the ‘Civil Penalty Notice’ that confirmed the penalty. The fixed penalty is set by European Union legislation and is calculated in Euros.  The payment is made to the U.K. regulator in GBP using conversion tables also defined by the European Union.  The actual sum paid in April 2017 was £537,295.

Item 4. Controls and Procedures
An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer.  As of the end of the period covered by this Report based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the design and operation of these disclosure controls and procedures were effective as of June 30, 2016.March 31, 2017.  
During the secondfirst quarter of 2016,2017, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.


Part II – OTHER INFORMATION
Item 1. Legal and Administrative Proceedings
We are a defendant in a number of legal 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.  
The following is a summary of certain proceedings involving us that were pending or contemplated as of March 31, 2017 under federal, state and international environmental laws:
In July 2015, we received a request for information from the EPA under Section 114 of the Clean Air Act regarding several tank batteries used in our Bakken operations.  BeginningWe executed a settlement agreement with the North Dakota Department of Health relating to this matter in the secondfourth quarter of 2016 we have been in settlement discussions withthat includes a base penalty of $294,000 that will be reduced under 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 undertaketerms by mitigating corrective actions which may increase our development and/or operating costs.actions.  We do not believe that any penalties or corrective action expenditures that may result from this matter will have a material adverse effect on our financial position, results of operation or cash flows.

In March 2016 we proactively notified the U.K. environmental regulator Business, Energy and Industrial Strategy (“BEIS”) that we had recognized an error in our carbon dioxide (“CO2”) emissions reporting.  In December 2016 we received a ‘Notice of Intent to Impose a Civil Penalty’ from BEIS for the self-disclosed underreporting of CO2 emissions.  The letter advised that the penalty for this event had initially been set at €946,360, however BEIS had reduced the amount to €630,906 in recognition of our self-reporting and proactive cooperation with the investigation. In February 2017 we received the final letter from BEIS, the ‘Civil Penalty Notice’ that confirmed the penalty. The fixed penalty is set by European Union legislation and is calculated in Euros.  The payment is made to the U.K. regulator in GBP using conversion tables also defined by the European Union.  The actual sum paid in April 2017 was £537,295.
Item 1A. Risk Factors
We are subject to various risks and uncertainties in the course of our business.  There have been no material changes to the risk factors under Item 1A. Risk Factors in our 20152016 Annual Report on Form 10-K.
