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.
These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2017 Annual Report on Form 10-K.  The results of operations for the first quarter of 2018 are not necessarily indicative of the results to be expected for the full year.
As a result of the sale of our Canadian business in 2017, we reflected this business as discontinued operations in all historical periods presented. Disclosures in this report related to results of operations and cash flows are presented on the basis of continuing operations unless otherwise stated. See Note 5 for discussion of the divestiture in further detail.
Reclassifications
In the first quarter of 2018 we adopted the new Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers using the modified retrospective method. To conform the historical presentation to our current presentation, we reclassified gains/losses arising from our commodity derivatives out of the revenue from contracts with customers line item and into a separate line, net gain (loss) on commodity derivatives, on the consolidated statements of income. Additionally, in the first quarter of 2018 we adopted the new pension accounting standards update on a retrospective basis, and reclassified the required cost elements from general and administrative expense into production expense, exploration expense, and other net periodic benefit costs. See Note 2 for further discussion of the adoption of these accounting standards.
2.   Accounting Standards
Not Yet Adopted
Lease accounting standard
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 does not apply to leases to explore for or use minerals, oil, natural gas and similar non-regenerative resources, including the intangible right to explore for those natural resources and rights to use the land in which those natural resources are contained. This standard is effective for us in the first quarter of 2019 and shall be applied using a modified retrospective approach at the beginning of the earliest period presented in the financial statements. Early adoption is permitted.
As a result of adoption of this standard, we anticipate to recognize a right of use asset and lease liability on the adoption date. We plan to apply practical expedients provided in the standard that allow, amongst others, not to reassess contracts that commenced prior to the adoption. We also anticipate to elect a policy not to recognize right of use assets and lease liabilities related to short-term leases.
We continue to evaluate our contracts and are gathering the necessary data to determine the financial impact of this standard on our consolidated financial statements and related disclosures. We are also evaluating our systems, processes, internal controls, and technology requirements and solutions needed to comply with the requirements of this standard. While we cannot currently estimate the financial impact this standard has on our consolidated financial statements, the adoption is anticipated to result in an increase in both assets and liabilities related to our leases.
Hedge accounting standard
In August 2017, the FASB issued a new accounting standards update that amends the hedge accounting model to enable entities to hedge certain financial and nonfinancial risk attributes previously not allowed. The amendment also reduces the overall complexity of documenting, assessing and measuring hedge effectiveness. This standard is effective for us in the first quarter of 2019. Early adoption is permitted in any interim or annual period. The amendment mandates modified retrospective adoption when accounting for hedge relationships in effect as of the adoption date. None of our derivative instruments are currently designated as hedges; as a result 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.

MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)

Goodwill standard
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. We anticipate the standard to 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. Since we plan to adopt the standard on a prospective basis, we do not expect an impact on our consolidated results of operations, financial position or cash flows for prior periods.
Financial instruments - credit losses
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.
Recently Adopted
Revenue recognition standard
On January 1, 2018, we adopted the new ASC Topic 606, Revenue from Contracts with Customers and all the related amendments ("new revenue standard") using the modified retrospective method. We evaluated the effect of transition by applying the provisions of the new revenue standard to contracts with remaining obligations as of January 1, 2018. No cumulative adjustment to retained earnings was necessary as a result of adopting this standard.
Results for reporting periods beginning after January 1, 2018 are presented under the new revenue standard, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting policies. The primary change relates to the presentation of marketing revenues and marketing expenses from the historical gross presentation to the current net presentation, included within revenues from contracts with customers, for a portion of our international contracts.
We concluded that the adoption of the new revenue standard did not result in any significant changes to our consolidated balance sheet or statement of cash flow. The following table summarizes the impacts of adopting the new revenue standard on our consolidated income statement for the quarter ended March 31, 2018.

Pension accounting standard
In the first quarter of 2018, we adopted the new accounting standards update that changes how employers that sponsor defined pension and/or other postretirement benefit plans present the net periodic benefit cost in the income statement. As a result, employers are required to 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. We adopted this standard on a retrospective basis, and reclassified the required cost elements from general and administrative expense into production expense, exploration expense, and other net periodic benefit costs. The adoption of this standard did not have a significant impact on our consolidated balance sheet or statement of cash flows. The following table summarizes the impacts of adopting this standard on our historical consolidated income statement for the quarter ended March 31, 2017.

Classification in the statement of cash flows
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 was effective for us in the first quarter of 2018, and was applied retrospectively. Adoption of this standard did not have a significant impact on our consolidated statements of cash flows.
Presentation of restricted cash in the statement of 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, we 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 was effective for us in the first quarter of 2018, and was applied retrospectively. Adoption of this standard did not have a significant impact on our consolidated statements of cash flows.
Accounting for sale or transfer of nonfinancial assets
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 was effective for us in the first quarter of 2018, and was applied using the modified retrospective approach. Adoption of this standard did not have a significant impact on our consolidated results of operations, financial position or cash flows.
Definition of a business
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 us 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 was effective for us in the first quarter of 2018, 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.

Financial instruments updates
In January 2016, the FASB issued an accounting standards update that addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. We adopted this standard in the first quarter of 2018. Adoption of this standard did not have a significant impact on our consolidated results of operations, financial position or cash flows.

4. Acquisitions
In the second quarter of 2017, we closed on our two acquisitions totaling approximately 91,000 net acres in the Permian basin of New Mexico. On May 1, 2017, we closed on our acquisition with BC Operating, Inc. and other entities for $1.1 billion in cash, subject to post-closing adjustments, to acquire approximately 70,000 net surface acres and current production of approximately 5,000 net barrels of oil equivalent per day. On June 1, 2017, we closed on our acquisition with Black Mountain Oil & Gas and other private sellers for approximately $700 million in cash, subject to post-closing adjustments, to acquire approximately 21,000 net surface acres. The purchase price for these acquisitions was paid with cash on hand. We accounted for these transactions as asset acquisitions, with substantially all of the purchase price allocated to unproved property within property, plant and equipment.
5.
Dispositions
International E&P Segment
On March 1, 2018, we closed on the sale of our subsidiary, Marathon Oil Libya Limited, which held our 16.33% non-operated interest in the Waha concessions in Libya, to a subsidiary of Total S.A. (Elf Aquitaine SAS) for proceeds of approximately $450 million, excluding closing adjustments, and recognized a pre-tax gain of $255 million.
In the third quarter of 2017, we entered into separate agreements to sell certain non-core properties in our International E&P segment for combined proceeds of $53 million, before closing adjustments. We closed on one of the asset sales in the fourth quarter of 2017 and recognized no net pre-tax gain or loss on sale. The remaining asset sale is expected to close during 2018 and is classified as held for sale in the consolidated balance sheet as of March 31, 2018, with total assets of $61 million and total liabilities of $4 million.

Canadian Business - Discontinued Operations
On May 31, 2017 we closed on the sale of our Canadian business, which included our 20% non-operated interest in the AOSP to Shell and Canadian Natural Resources Limited for $2.5 billion, excluding closing adjustments. Under the terms of the agreement, $1.8 billion was paid to us upon closing and the remaining proceeds were paid in the first quarter of 2018. At closing we received two notes receivable for the remaining proceeds, each with a face value of $375 million, which we received payment for in the first quarter of 2018. In the first quarter of 2017, we recorded a non-cash impairment charge of $6.6 billion (after-tax of $4.96 billion) primarily related to the property, plant and equipment of our Canadian business. As the effective date of the transaction is January 1, 2017, we recorded a loss on sale of $43 million during the second quarter of 2017 due to second quarter results of operations from our Canadian business that were recorded in our financial statements, but transferred to the buyer upon closing.
Our Canadian business is reflected as discontinued operations in the consolidated statements of income and the consolidated statements of cash flows for all periods presented.

The pricing in our hydrocarbon sales agreements are variable, determined using various published benchmarks which are adjusted for negotiated quality and location differentials. As a result, revenue collected under our agreements with customers is highly dependent on the market conditions and may fluctuate considerably as the hydrocarbon market prices rise or fall. Typically, our customers pay us monthly, within a short period of time after we deliver the hydrocarbon products. As such, we do not have any financing element associated with our contracts. We do not have any issues related to returns or refunds, as product specifications are standardized for the industry and are typically measured when transferred to a common carrier or midstream entity, and other contractual mechanisms (e.g., price adjustments) are used when products do not meet those specifications.
In limited cases, we may also collect advance payments from customers as stipulated in our agreements; payments in excess of recognized revenue are recorded as contract liabilities on our consolidated balance sheet.
Under our hydrocarbon sales agreements, the entire consideration amount is variable either due to pricing and/or volumes. We recognize revenue in the amount of variable consideration allocated to distinct units of hydrocarbons transferred to a customer. Such allocation reflects the amount of total consideration we expect to collect for completed deliveries of hydrocarbons and the terms of variable payment relate specifically to our efforts to satisfy the performance obligations under these contracts. Our performance obligations under our hydrocarbon sales agreements are to deliver either the entire production from the dedicated wells or specified contractual volumes of hydrocarbons.
We often serve as the operator for jointly owned oil and gas properties. As part of this role, we perform activities to explore, develop and produce oil and gas properties in accordance with the joint operating arrangement and collective decisions of the joint parties. Other working interest owners reimburse us for costs incurred based on our agreements. We determined that these activities are not performed as part of customer relationships, in accordance with the new revenue standard, and such reimbursements will continue to not be recorded as revenues within the scope of the new revenue standard.
In addition, we commonly market the share of production belonging to other working interest owners as the operator of jointly owned oil and gas properties. We concluded that those marketing activities are carried out as part of the collaborative arrangement, and we do not purchase or otherwise obtain control of other working interest owners’ share of production. Therefore, we act as a principal only in regards to the sale of our share of production and recognize revenue for the volumes associated with our net production.
Crude oil and condensate
For the crude sales agreements, we satisfy our performance obligations and recognize revenue once customers take control of the crude at the designated delivery points, which include pipelines, trucks or vessels.
Natural gas and NGLs
When selling natural gas and NGLs, we engage midstream entities to process our production stream by separating natural gas from the NGLs. Frequently, these midstream entities also purchase our natural gas and NGLs under the same agreements. In these situations, we determined the performance obligation is complete and satisfied at the tailgate of the processing plant when the natural gas and NGLs become identifiable and measurable products. We determined the plant tailgate is the point in time where control, as defined in the new revenue standard, is transferred to midstream entities and they are entitled to significant risks and rewards of ownership of the natural gas and NGLs.
The amounts due to midstream entities for gathering and processing services are recognized as shipping and handling cost, as part of the other operating expense in our consolidated statement of income, since we make those payments in exchange for distinct services. Under some of our natural gas processing agreements, we have an option to take the processed natural gas and NGLs in-kind and sell to customers other than the processing company. In those circumstances, our performance obligations are complete after delivering the processed hydrocarbons to the customer at the designated delivery points, which may be the tailgate of the processing plant or an alternative delivery point requested by the customer.

11

MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)

We have “percentage-of-proceeds” arrangements with some midstream entities where they retain a percentage of the proceeds collected for selling our processed natural gas and NGLs as compensation for their processing and marketing services. We recognize revenue for the gross sales volumes and recognize the proceeds retained by midstream companies as shipping and handling cost.

The contract asset represents the crude oil delivered to one of our customers in the U.K. for which payment will be collected over time as it becomes due under the pricing terms stipulated in the sales agreement. As a practical expedient, when the balance of this U.K. customer is a contract asset, we do not adjust revenue for the effects of a significant financing element as the period between when crude oil is delivered to the customer and when payment is expected to be received is one year or less at contract inception.
Significant changes in the contract asset balance during the period are as follows.

7.    Segment Information
  We have two reportable operating segments. Both of these segments are organized and managed based upon both geographic location and the nature of the products and services it offers.
United States E&P ("U.S. E&P") – explores for, produces and markets crude oil and condensate, NGLs and natural gas in the United States
International E&P ("Int’l E&P") – explores for, produces and markets crude oil and condensate, NGLs and natural gas outside of the United States and produces and markets products manufactured from natural gas, such as LNG and methanol, in Equatorial Guinea (“E.G.”)
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 our operating segments, net of income taxes. A portion of our corporate and operations general and administrative support 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, 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.

8.    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.

For the three months ended March 31, 2018 and 2017, our effective income tax rates from continuing operations were as follows:
 
 
Three Months Ended March 31,
 
 
2018
 
2017
Effective income tax expense (benefit) rate from continuing operations
 
32
%
 
213
%

The following items caused the effective tax rates from continuing operations to be different from our U.S. statutory tax rate of 21% and 35% respectively for 2018 and 2017:

During the three months ended March 31, 2018, we incurred tax expense in Libya of $162 million, and maintained our valuation allowance on our net federal deferred tax assets in the U.S.
During the three months ended March 31, 2017, we incurred tax expense in Libya of $45 million, settled our 2011-2013 Alaska income tax audit resulting in a tax benefit of $13 million, and maintained our valuation allowance on our net federal deferred tax assets in the U.S.
Excluding Libya, the effective income tax expense and benefit rates from continuing operations were an expense of 2% and a benefit of 16% for the first quarter of 2018 and 2017, respectively. As a result of the sale of our Libya subsidiary, see Note 5 for further detail, we do not expect to incur further tax expense in 2018 related to our Libya subsidiary. During 2018 and 2017, income taxes for Libya were recorded as a discrete item due to the uncertainty around the timing of future production and sales volumes.

On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Tax Reform Legislation”). Tax Reform Legislation, which is also commonly referred to as “U.S. tax reform”, significantly changes U.S. corporate income tax laws by, among other things, reducing the U.S. corporate income tax rate to 21% starting in 2018, and repeal of the corporate alternative minimum tax, and a one-time deemed repatriation of accumulated foreign earnings. In the fourth quarter of 2017, we remeasured our deferred taxes at 21%, in accordance with U.S. GAAP standards. Once we finalize certain tax positions when we file our 2017 federal tax return, we will be able to conclude whether any further adjustments are required to our net tax position as of December 31, 2017. Any adjustments to these provisional amounts will be reported as a component of income tax expense (benefit) in the reporting period in which any such adjustments are determined, which will be no later than the fourth quarter of 2018. As of the first quarter of 2018, there is no impact on tax expense with respect to the finalization of tax positions taken due to Tax Reform Legislation.
9.   Inventories
 Crude oil and natural gas are recorded at weighted average cost and carried at the lower of cost or net realizable value. Supplies and other items consist principally of tubular goods and equipment which are valued at weighted average cost and reviewed periodically for obsolescence or impairment when market conditions indicate.

Derivatives Not Designated as Hedges
Terminated Interest Rate Swaps
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 were probable to be refinanced by us in 2018, specifically interest rate risk associated with future changes in the benchmark treasury rate. During the second quarter of 2017, we de-designated the forward starting interest rate swaps previously designated as cash flow hedges. In the third quarter of 2017, the forecasted transaction consummated and we issued $1 billion in senior unsecured notes. As a result, we terminated our forward starting interest rate swaps during the third quarter of 2017.

The following table presents, by maturity date, information about our forward starting interest rate swap agreements, including the rate, which were terminated in the third quarter of 2017.

Commodity Derivatives
We have entered into multiple crude oil and natural gas derivatives indexed to NYMEX WTI and Henry Hub related to a portion of our forecasted United States E&P sales through 2020. These commodity derivatives consist of three-way collars, swaps and basis swaps. 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.

(a)  
Derivative instruments are recorded on a net basis in our balance sheet. See Note 12.
Commodity derivatives include three-way collars, swaps, and basis swaps. These instruments are measured at fair value using either a Black-Scholes or a modified Black-Scholes Model. For swaps and basis swaps, inputs to the models include only commodity prices and interest rates and are categorized as Level 1 because all assumptions and inputs are observable in active markets throughout the term of the instruments. For three-way collars, inputs to the models include commodity prices, and implied volatility and are categorized as Level 2 because predominantly all assumptions and inputs are observable in active markets throughout the term of the instruments.
Historically, both our interest rate swaps and forward starting interest rate swaps were measured at fair value with a market approach using actionable broker quotes, which are Level 2 inputs. See Note 12 for additional discussion of the types of derivative instruments we used.
Fair Values- Nonrecurring
The following table shows the values of assets, by major category, measured at fair value on a nonrecurring basis in periods subsequent to their initial recognition.

International E&P
We recorded proved property impairments of $8 million, to a fair value of $50 million, on a non-core property in our International E&P segment primarily as a result of anticipated sales proceeds. The fair value was measured using the market approach, based upon anticipated sales proceeds less costs to sell. This resulted in a Level 2 classification. See Note 5 for relevant detail regarding dispositions.

Canadian business discontinued operations
As a result of our announced disposition of our Canadian business in the first quarter of 2017, we recorded a pre-tax non-cash impairment charge of $6.6 billion primarily related to property, plant and equipment. This impairment was recorded for excess net book value over anticipated sales proceeds less costs to sell. Fair values of assets held for sale were determined based upon the anticipated sales proceeds less costs to sell, which resulted in a Level 2 classification. See Note 5 for relevant detail regarding dispositions.
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.
The following table summarizes financial instruments, excluding receivables, payables and derivative financial instruments, and their reported fair values by individual balance sheet line item at March 31, 2018 and December 31, 2017.

(b) Excludes capital leases, debt issuance costs and interest rate swap adjustments.
Fair values of our notes receivable and 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.
All 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 our debt.
14.  Debt
Revolving Credit Facility
As of March 31, 2018, we had no borrowings against our $3.4 billion revolving credit facility (the “Credit Facility”), as described below.
The Credit Facility includes a covenant requiring that our ratio of total debt to total capitalization not exceed 65% as of the last day of each fiscal quarter. If an event of default occurs, the lenders holding more than half of the commitments may terminate the commitments under the Credit Facility and require the immediate repayment of all outstanding borrowings and the cash collateralization of all outstanding letters of credit under the Credit Facility. As of March 31, 2018, we were in compliance with this covenant with a debt-to-capitalization ratio of 31%.
Long-term debt
As of March 31, 2018 we had $5.5 billion in long-term debt outstanding, with our next debt maturity in the amount of $600 million due in 2020.

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

During the first three months of 2018, 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 three months of 2018, we made contributions of $29 million to our funded pension plans and we expect to make additional contributions up to an estimated $36 million over the remainder of 2018.  During the first three months of 2018, we made payments of $8 million and $6 million related to unfunded pension plans and other postretirement benefit plans, respectively.

20.   Commitments and Contingencies
The U.K. tax authorities have challenged the timing of deductibility for certain Brae area decommissioning costs, which we claimed for U.K. corporation tax purposes.  The dispute relates to the timing of the deduction and does not dispute the general deductibility of decommissioning costs. In the third quarter of 2017, a hearing took place at the U.K.’s First-tier Tribunal with respect to this tax deduction.  In the fourth quarter of 2017, we received notification from the U.K.’s First-tier Tribunal that the judge sided with the U.K. tax authorities with respect to the timing of the decommissioning cost deductions. We intend to appeal this decision and estimate that any revisions to current and deferred tax liabilities, if we do not prevail in the appeals process, would have no cumulative adverse earnings impact on our consolidated results of operations. In accordance with U.K. regulations, in the fourth quarter of 2017, we paid the amount of tax and interest in question, approximately $108 million, prior to our appeal. As a result of the negative ruling we no longer consider this position to be more-likely-than-not to be sustained and in the fourth quarter 2017 created an uncertain tax position related to the Brae area decommissioning costs. The payment of the tax and interest to the U.K. tax authorities is not to settle the position, but a regulatory requirement to appeal in the U.K. If we ultimately prevail in appeals, the U.K. tax authorities will refund the tax and interest, however, if we ultimately lose in appeals no material future payments related to this issue will be required. 
We are continuously undergoing examination of our U.S. federal income tax returns by the IRS. These audits have been completed through the 2014 tax year, except for tax years 2010 and 2011. During the third quarter of 2017, we received a partnership adjustment notification related to the 2010 and 2011 tax years, for which we have filed a Tax Court Petition in the fourth quarter of 2017.  We believe that it is more likely than not that we will prevail.
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.

Executive Overview
Operations
Market Conditions

Critical Accounting Estimates
Accounting Standards Not Yet Adopted
Cash Flows
Liquidity and Capital Resources
Environmental Matters and Other Contingencies
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the preceding consolidated financial statements and notes in Item 1.
Executive Overview
We are an independent exploration and production company based in Houston, Texas focused on U.S. unconventional resource plays with operations in the United States, Europe and Africa. Total proved reserves were 1.4 billion boe at December 31, 2017, including 199 mmboe in Libya, and total assets were $21.6 billion at March 31, 2018. During the first quarter 2018, we continued our portfolio transformation, maintained a strong balance sheet and delivered solid operational performance across our portfolio.
Key highlights include the following:
Simplifying and concentrating our portfolio
On March 1, 2018 we closed on the sale of our Libya subsidiary for proceeds of approximately $450 million resulting in a gain of $255 million.
Captured more than 250,000 net acres in multiple new plays in the last year, including a largely contiguous position in the emerging Louisiana Austin Chalk play at a cost of less than $900 per acre.
Liquidity
At the end of the first quarter 2018, we had approximately $5.0 billion of liquidity, comprised of $1.6 billion in cash and an undrawn $3.4 billion revolving credit facility.
In March of 2018, we received the expected cash proceeds of $750 million from the sale of our Canadian business.
Financial and operational results
Total net sales volumes from continuing operations, including Libya are 431 mboed. This represents an increase in net sales volumes of 29% compared to the same quarter last year and includes a 40% increase from the U.S resource plays to 268 mboed.
Wells to sales in the first three months of 2018 increased over 10% in the U.S. resource plays.
Cash provided by operating activities from continuing operations is $649 million for the first three months of 2018 as a result of increased price realizations and sales volumes.
Our net income per share from continuing operations was $0.42 in the first quarter of 2018 as compared to a net loss per share of $0.06 in the same period last year. Included in the first quarter 2018 net income results are:
An increase in revenues of approximately 75% to $1,537 million compared to the same quarter last year as a result of increased price realizations and sales volumes across our portfolio.
Net loss on commodity derivatives was $102 million compared to a net gain of $81 million in the same quarter last year due to the increases in long-term commodity prices during the first quarter 2018.
Net gain on disposal of assets from the sale of our Libya subsidiary for $255 million.
Production expense, DD&A and other operating expenses increased 17% primarily as a result of sales volumes increasing by 29% during the quarter.
Net interest and other decreased by $33 million to $45 million primarily due to the reduction of total debt of approximately $1.75 billion in the second half of 2017.
Our provision for income taxes increased $134 million compared to the same quarter last year primarily due to an increase in Libya tax expense as a result of higher sales volumes.

Eagle Ford – Our net sales volumes were 104 mboed in the first quarter of 2018 which was 5% higher compared to the prior year quarter. Enhanced completion designs continued to deliver solid results outside of core Karnes County, where the four-well Carpenter Kellner pad and the four-well Guajillo West pad achieved strong well performance. We continued our focus on cash flow in the quarter through a combination of well performance and oil realizations that averaged $1.50 above WTI due to strong LLS-based pricing.
Bakken – Our net sales volumes were 74 mboed compared to 48 mboed in the prior year quarter. We brought 11 gross company-operated wells to sales in the first quarter 2018, six of which were in core Hector which achieved strong well results. During the first quarter 2018 our Arkin well in Hector set a new Williston Basin Three Forks record for 30-day IP oil rate. We continue to optimize completion designs to improve well productivity, increase capital efficiency and reduce costs.
Oklahoma – Our net sales volumes in the first quarter 2018 increased by more than 65% from the year ago quarter, with net sales volumes of 74 mboed. We brought 17 gross operated wells to sales primarily focused on Meramec leasehold activity in the STACK. This largely completes the STACK leasehold program for the year, and allows for the transition to pad drilling for the remainder of 2018. In the normally pressured STACK, improved drilling efficiencies and optimized completion designs resulted in completed well costs for first quarter standard-lateral Meramec wells averaging $4 million.
Northern Delaware – Our net sales volumes were 16 mboed in the first quarter 2018. We brought nine gross company-operated wells to sales across the Malaga, Red Hills and Ranger areas in Eddy and Lea Counties. Two wells from the Cypress infill pilot came to sales ahead of schedule in the last week of the quarter. We are currently benefiting from our Midland-Cushing basis swaps, with open positions that include 10,000 bopd hedged at a discount of less than $1 to WTI for the second half of 2018 and all of 2019. See Note 12 to the consolidated financial statements for further information.

International E&P
Net sales volumes were higher in the first quarter of 2018 compared to the first quarter of 2017 primarily due to the resumption of sales volumes and production in Libya and timing of our liftings in the U.K. The following table provides details regarding net sales volumes for our significant operations within this segment.

United KingdomFirst quarter 2018 net sales volumes were higher compared to the first quarter of 2017 primarily due to the timing of liftings, which resulted in an increase in net sales volumes during the first quarter of 2018.
Libya – During the first quarter of 2018 we closed on the sale of our operations in Libya, see Note 5 to the consolidated financial statements for further information.

Market Conditions
Crude oil and condensate and NGLs benchmarks increased in the first quarter of 2018 as compared to the same period in 2017; as a result, we experienced increased price realizations associated with those benchmarks.

Our U.K. liquid hydrocarbon production is generally sold in relation to the Brent crude benchmark. Our production from the Alba field in E.G. is condensate and gas. Condensate is sold at market prices and the gas is shipped to the onshore Alba Plant. The Alba Plant extracts NGLs and secondary condensate, which have been supplied under a long-term contract at a fixed price, leaving dry natural gas. The extracted NGLs and secondary condensate are sold by Alba Plant at market prices, with our share of its income/loss reflected in income from equity method investments, and the dry natural gas from Alba Plant is supplied to AMPCO and EGHoldings under long-term contracts at fixed prices. Therefore, our reported average realized prices for condensate, NGLs and natural gas will not fully track market price movements. Because of the location and limited local demand for natural gas in E.G., we consider the prices under the contracts with Alba Plant LLC, EGHoldings and AMPCO to be comparable to the price that could be realized from transactions with unrelated parties in this market under the same or similar circumstances. EGHoldings and AMPCO process the gas into LNG and methanol, which are sold at market prices, with our share of their income/loss reflected in the income from equity method investments line item on the consolidated statements of income. Although uncommon, any dry gas not sold is returned offshore and re-injected into the Alba field for later production.

Net gain (loss) on commodity derivatives decreased $183 million in the first quarter of 2018 compared to the same period in 2017. We have entered into multiple crude oil and natural gas derivative contracts indexed to NYMEX WTI and Henry Hub. We record commodity derivative gains/losses as the index pricing changes from period to period. See Note 12 to the consolidated financial statements for further information.
Marketing revenues decreased $34 million in the first quarter of 2018 from the comparable 2017 period. This decrease is the result of adopting the new revenue standard, ASC Topic 606, Revenue from Contracts with Customers during the first quarter of 2018. As a result of this standard, we have changed our presentation of marketing revenues and marketing expenses from the historical gross presentation to a net presentation.
Income from equity method investments decreased $32 million in the first quarter of 2018 from the comparable 2017 period. This decrease is the result of lower volumes at our LNG production facility primarily driven by planned maintenance activities during the first quarter 2018.

29



Net gain on disposal of assets increased $256 million in the first quarter of 2018 primarily related to the gain on sale of our subsidiary Marathon Oil Libya Limited, which holds our 16.33% non-operated interest in the Waha concessions in Libya, during the first quarter of 2018. See Note 5 to the consolidated financial statements for further information.
Production expenses increased $64 million in the first quarter of 2018 versus the same period in 2017 primarily due to higher sales volumes across our U.S. and International E&P segments. United States E&P increased $42 million primarily due to our entry into Northern Delaware in 2017, as wells as new wells to sales across all U.S. resource plays. International E&P increased $23 million primarily due to the timing of our U.K. liftings, which resulted in increased sales volumes during the first quarter 2018.
The first quarter 2018 production expense rate (expense per boe) for International E&P increased due to sales volume mix within our segment.
The following table provides production expense rates for each segment:

Marketing costs decreased $34 million in the first quarter of 2018 from the comparable 2017 period, consistent with the marketing revenues change discussed above.
Other operating expenses increased $41 million in the first quarter of 2018 primarily due to an increase in our shipping and handling expenses as a result of increased sales volumes in our United States E&P segment.
Exploration expenses include unproved property impairments, dry well costs, geological and geophysical, and other, which increased $24 million in the first quarter of 2018. The increase in unproved property impairments is primarily a result of the acquisition of Northern Delaware in 2017.

Depreciation, depletion and amortization increased $34 million in the first quarter of 2018. United States E&P DD&A expense increased by $56 million primarily due to higher sales volumes across all U.S. resource plays, as well as our acquisition and development of Northern Delaware in 2017. In our International E&P segment, we had a decrease of $21 million primarily the result of lower estimated U.K. asset retirement costs during the second half of 2017. 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.

30



The DD&A rate (expense per boe), which is impacted by changes in reserves, capitalized costs, and sales volume mix by field, can also impact our DD&A. Our United States E&P DD&A rate decreased in the first quarter of 2018 primarily due to increased proved developed reserves in our U.S. resource plays in 2017; as well as reduced capitalized costs relating to the Gulf of Mexico non-cash impairment charge in 2017. The DD&A rate for our International E&P decreased as a result of the reduction of our estimated U.K. asset retirement costs in the second half of 2017.

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. Taxes other than income increased $25 million in the first quarter of 2018 versus the same period in 2017. The increase is primarily due to an increase in sales volumes during the first quarter 2018. Additionally, during the first quarter of 2018 the State of Oklahoma approved an increase to the gross production tax from 2% to 5% on all existing and new wells for the first thirty-six months, effective July 1, 2018.

Net interest and other decreased $33 million in the first quarter of 2018 versus the same period in 2017. This decrease was primarily due to the reduction of approximately $1.75 billion in net debt during 2017.
Other net periodic benefit costs decreased $7 million during the first quarter of 2018 primarily due to reduced pension settlement charges. See Note 16 to the consolidated financial statements for further information.
Provision (benefit) for income taxes reflects an effective tax rate from continuing operations of 32% in the first quarter of 2018, as compared to an effective tax rate of 213% in the first quarter of 2017. See Note 8 to the consolidated financial statements for more detail discussion concerning the rate changes.
Discontinued operations are presented net of tax. See Note 5 to the consolidated financial statements for financial information concerning our discontinued operations.

Segment Income (Loss)
Segment income (loss) represents income (loss) from continuing operations excluding certain items not allocated to operating segments, net of income taxes. A portion of our corporate and operations general and administrative support costs are not allocated to the operating segments. Gains or losses on dispositions, certain impairments, 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.

(a) We entered into an agreement in the first quarter of 2017 to sell our Canadian business which is reflected as discontinued operations in all periods presented.
 United States E&P segment income increased $204 million after-tax in the first quarter of 2018 primarily due to higher price realizations and an increase in sales volumes. This increase in sales volumes resulted in an increase to production expenses, other operating expenses, DD&A and taxes other than income which partially offset the increase to revenues.
International E&P segment income increased $39 million after-tax in the first quarter of 2018 primarily due to higher price realizations and an increase in sales volumes in the U.K. and Libya. This increase in sales volumes resulted in an increase in production expense and income tax provision which partially offset the increase to revenues.

Cash flows generated from operating activities in the first three months of 2018 were higher as commodity prices and price realizations improved compared to the first three months of 2017. Consolidated average crude oil and condensate price realizations increased by approximately 29% during the first three months of 2018 as compared to the prior period. This increase in price realization and net sales volumes resulted in increased cash flows generated from operating activities.
Proceeds from the disposals of assets for the first three months of 2018 are primarily from the disposal of our non-operated interest in Libya and the remaining proceeds of $750 million from the sale of our Canadian business; see Note 5 to the consolidated financial statements for further information concerning dispositions.
Additions to property, plant and equipment in the first three months of 2018 were consistent with our $2.3 billion Development Capital Program. The following table shows capital expenditures related to continuing operations by segment and reconciles to additions to property, plant and equipment as presented in the consolidated statements of cash flows:

In the first quarter of 2017, we paid $180 million of aggregate deposits into escrow related to our acquisition of the Northern Delaware assets. See Note 4 to the consolidated financial statements for additional information.
Included within other uses of cash and cash equivalents is $72 million relating to our resource play leasing and exploration capital expenditures. During the first quarter 2018 our resource play leasing and exploration capital expenditures totaled $94 million, inclusive of costs included within property, plant and equipment and exploration expense.
The Board of Directors approved a $0.05 per share dividend for the fourth quarter of 2017, which was paid in the first quarter of 2018. See Capital Requirements below for additional information about the first quarter dividend.

33



Liquidity and Capital Resources
Our main sources of liquidity are cash and cash equivalents, internally generated cash flow from operations, sales of non-core assets, capital market transactions, and our revolving Credit Facility. At March 31, 2018, we had approximately $5.0 billion of liquidity consisting of $1.6 billion in cash and cash equivalents and $3.4 billion available under our revolving Credit Facility. Our working capital requirements are supported by these sources and we may draw on our revolving 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 program. Because of the alternatives available to us as discussed above, we believe that our short-term and long-term liquidity are 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.
General economic conditions, commodity prices, and financial, business and other factors could affect our operations and our ability to access the capital markets. Our corporate credit ratings remained unchanged as of March 31, 2018: Standard & Poor's Ratings Services BBB- (stable); Fitch Ratings BBB (stable); and Moody's Investor Services, Inc. Ba1 (stable). A 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, 2017 for a discussion of how a further downgrade in our credit ratings could affect us.
Capital Resources
Credit Arrangements and Borrowings
At March 31, 2018, we had no borrowings against our revolving credit facility.
At March 31, 2018, we had $5.5 billion in long-term debt outstanding, with our next debt maturity in the amount of $600 million due in 2020. 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 debt and equity securities. 
Asset Disposal
In the third quarter of 2017, we entered into agreements to sell certain non-core properties in our International E&P segment for combined proceeds of $53 million, before closing adjustments. We have closed on one of the asset sales in 2017, and we expect the remaining asset sale to close during 2018.
Debt-To-Capital Ratio
The Credit Facility includes a covenant requiring that our ratio of total debt to total capitalization not exceed 65% as of the last day of the fiscal quarter. Our debt-to-capital ratio was 31% at March 31, 2018, compared to 32% at December 31, 2017.

Other Expected Cash Outflows
On April 26, 2018, our Board of Directors approved a dividend of $0.05 per share for the first quarter of 2018 payable June 11, 2018 to stockholders of record at the close of business on May 16, 2018.
As of March 31, 2018, we plan to make contributions of up to $36 million to our funded pension plans during the remainder of 2018.
Contractual Cash Obligations
As of March 31, 2018, there are no material changes to our consolidated cash obligations to make future payments under existing contracts, as disclosed in our 2017 Annual Report on Form 10-K.
Environmental Matters and Other Contingencies
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 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.  
There have been no significant changes to our environmental matters and other contingencies subsequent to December 31, 2017. See Note 20 to the consolidated financial statements for a description of other contingencies.
Forward-Looking Statements
This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”). All statements other than statements of historical fact, including without limitation statements regarding our future performance, business strategy, reserve estimates, asset quality, production guidance, drilling plans, capital plans, cost and expense estimates, asset acquisitions and dispositions, future financial position and other plans and objectives for future operations, are forward-looking statements.

While we believe our assumptions concerning future events are reasonable, a number of factors could cause results to differ materially from those projected, including, but not limited to:
conditions in the oil and gas industry, including supply and demand levels for crude oil and condensate, NGLs and natural gas and the resulting impact on price;
changes in expected reserve or production levels;
changes in political and economic conditions in the jurisdictions in which we operate, including changes in foreign currency exchange rates, interest rates, inflation rates, and global and domestic market conditions;
risks related to our hedging activities;
capital available for exploration and development;
the inability of any party to satisfy closing conditions with respect to our asset acquisitions and dispositions;
drilling and operating risks;
well production timing;
availability of drilling rigs, materials and labor, including the costs associated therewith;
difficulty in obtaining necessary approvals and permits;
non-performance by third parties of contractual obligations;
unforeseen hazards such as weather conditions, acts of war or terrorist acts and the governmental or military response thereto;
cyber-attacks;
changes in safety, health, environmental, tax and other regulations;
other geological, operating and economic considerations; and
the risk factors, forward-looking statements and challenges and uncertainties described in our 2017 Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and other filings with the SEC.

35



All forward-looking statements included in this report are based on information available to us on the date of this report. Except as required by law, we undertake no obligation to revise or update any forward-looking statements as a result of new information, future events or otherwise.

Interest Rate Risk Our portfolio of long-term debt is substantially comprised of fixed rate instruments. Our sensitivity to interest rate movements and corresponding changes in the fair value of our fixed-rate debt portfolio affects our results of operations and cash flows only when we elect to repurchase or otherwise retire fixed-rate debt at prices different than carrying value. Sensitivity analysis of the incremental effect of a hypothetical 10% change in interest rates on our financial assets and liabilities as of March 31, 2018, is provided in the following table.

Fair value was based on market prices where available, or current borrowing rates for financings with similar terms and maturities.
(c) 
Excludes capital leases.
    
Counterparty Risk We are also exposed to financial risk in the event of nonperformance by counterparties. If commodity prices fall below current levels, some of our counterparties may experience liquidity problems and may not be able to meet their financial obligations to us. We review the creditworthiness of counterparties and use master netting agreements when appropriate.
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 March 31, 2018.  
During the first three months of 2018, 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.

Item 1. Legal 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.  
See Note 20 to the consolidated financial statements included in Part I, Item I for a description of such legal and administrative proceedings.
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 2017 Annual Report on Form 10-K.
