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 second quarter and first six months 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 this 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 revenues from contracts with customers line 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.
We will adopt this new standard in the first quarter of 2019 using a modified retrospective approach and will 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 installed and are in the process of configuring software that we believe will facilitate the adoption of the standard. We are also evaluating our processes and internal control environment concurrent with the adoption of this standard. While we have yet to finalize the estimated impact this standard will have 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 (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 (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 plan to adopt the standard on a prospective basis, and do not expect a material 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 tables summarize the impacts of adopting the new revenue standard on our consolidated income statement for the three and six months period ended June 30, 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 tables summarize the impacts of adopting this standard on our historical consolidated income statement for the three and six months period ended June 30, 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.

MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)

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.

Income (Loss) per Common Share
Basic income (loss) per share is based on the weighted average number of common shares outstanding.  Diluted income per share assumes exercise of stock options in all periods, provided the effect is not antidilutive. The per share calculations below exclude 6 million and 8 million of stock options for the three and six months period ended June 30, 2018 and 12 million stock options for the three and six months period ended June 30, 2017 that were antidilutive.

4. Acquisitions
In the second quarter of 2017, we closed on two acquisitions which included approximately 91,000 net acres in the Permian basin of New Mexico. The first acquisition with BC Operating, Inc. and other entities closed for approximately $1.1 billion in cash and the second acquisition with Black Mountain Oil & Gas and other private sellers closed for approximately $700 million in cash. These acquisitions were paid with cash on hand and accounted for as asset acquisitions, with substantially all of the purchase price allocated to unproved property within property, plant and equipment.
5.
Dispositions
United States E&P Segment
In the second quarter of 2018, we entered into separate agreements to sell non-core, non-operated conventional properties, primarily in the Gulf of Mexico, for combined net proceeds of $16 million, before closing adjustments. These transactions met the criteria for assets held for sale which is reflected in the consolidated balance sheet at June 30, 2018, with total assets of $53 million and total liabilities, relating to asset retirement obligations, of $80 million. These transactions closed during July of 2018.
International E&P Segment
In the second quarter of 2018, we entered into an agreement to sell a non-core property for proceeds of $56 million, before closing adjustments. This property is classified as held for sale in the consolidated balance sheet at June 30, 2018, with total assets of $77 million, total liabilities of $11 million and expected to close during 2018.
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 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 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 June 30, 2018, with total assets of $62 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. At closing we received two notes receivable for a combined $750 million for the remaining proceeds, which was received 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. 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. As the effective date of the transaction was 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 following table contains select amounts reported in our historical consolidated statements of income and consolidated statements of cash flows as discontinued operations:

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

12

MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)

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, 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.
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 crude oil delivered in the U.K. to a customer 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

7.    Segment Information
  We have two reportable operating segments. Both of these segments are organized and managed based upon 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 second quarter and six months ended June 30, 2018 and 2017, our effective income tax rates from continuing operations were as follows:
 
 
Three Months Ended June 30,
 
Six Months Ended June 30,
 
 
2018

2017
Effective income tax expense (benefit) rate from continuing operations
 
31
%
 
37
%
 
32
%
 
59
%

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% for 2018 and 2017:

Income taxes for the second quarter 2018 were impacted by foreign currency revaluation. During the six months ended June 30, 2018 income taxes were impacted by tax expense in Libya of $162 million, and we maintained our valuation allowance on our net federal deferred tax assets in the U.S.
Income taxes for the second quarter 2017 were impacted by tax expense in Libya of $32 million. During the six months ended June 30, 2017, we incurred tax expense in Libya of $77 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 10% and a benefit of 1% for the six months ended June 30, 2018 and 2017. As a result of the sale of our Libya subsidiary in the first quarter of 2018, see Note 5 for further detail, we do not expect to incur further tax expense 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 ("AMT"), 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. We plan to finalize certain tax positions when we file our 2017 federal tax return, and subsequently 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 second quarter of 2018, there are no material impacts 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.

2018 - During the first six months of 2018 we recorded pre-tax non-cash proved property impairments of $42 million, to a fair value of $69 million, primarily as a result of anticipated sales proceeds for certain non-core proved properties in our International and United States E&P segments. The related fair value measurement utilized the market approach, based upon anticipated sales proceeds less costs to sell which resulted in a Level 2 classification. See Note 5 for discussion of the divestitures in further detail.
12. Derivatives
For further information regarding the fair value measurement of derivative instruments, see Note 13. All of our commodity derivatives and historical interest rate derivatives are subject to enforceable master netting arrangements or similar agreements under which we may report net amounts.

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 sets forth the net impact of the terminated forward starting interest rate swap derivatives de-designated as cash flow hedges on other comprehensive income (loss).

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 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. The following table sets forth outstanding derivative contracts as of June 30, 2018 and the weighted average prices for those contracts:

The mark-to-market impact and settlement of these commodity derivative instruments appears in net gain (loss) on commodity derivatives in our consolidated statements of income for the three and six month periods ended June 30, 2018 and 2017. The mark-to-market impact for the three and six month periods ended June 30, 2018 was a loss of $45 million and a loss of $88 million compared to a gain of $43 million and $120 million for the same respective periods in 2017. Net settlements of commodity derivative instruments for the three and six month periods ended June 30, 2018 was a loss of $107 million and $166 million compared to a gain of $13 million and $17 million for the respective periods in 2017.

(a)  
Derivative instruments are recorded on a net basis in our balance sheet. See Note 12.
Commodity derivatives include three-way collars and basis swaps. These instruments are measured at fair value using either a Black-Scholes or a modified Black-Scholes Model. For 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 - Goodwill
As of June 30, 2018, our consolidated balance sheet included goodwill of $98 million. Goodwill is tested for impairment on an annual basis, or between annual tests when events or changes in circumstances indicate the fair value may have been reduced below its carrying value. Goodwill is tested for impairment at the reporting unit level. Our reporting units are the same as our reporting segments, of which only International E&P includes goodwill. Our policy is to first assess the qualitative factors in order to determine whether the fair value of our International E&P reporting unit is more likely than not less than its carrying amount. Certain qualitative factors used in our evaluation include, among other things, the results of the most recent quantitative assessment of the goodwill impairment test, macroeconomic conditions; industry and market conditions (including commodity prices and cost factors); overall financial performance; and other relevant entity-specific events. If, after considering these events and circumstances we determined that it is more likely than not the fair value of the International E&P reporting unit is less than its carrying amount, a quantitative goodwill test is performed.
During the second quarter of 2018, we performed our annual impairment test of goodwill using the qualitative assessment. Our qualitative assessment considered the significant excess fair value over carrying value in our most recent step one test (second quarter 2017) and noted a general improvement in the qualitative factors described above which could have a positive or negative impact on goodwill. After assessing the totality of the qualitative factors, our assessment did not indicate that it is more likely than not that the fair value is less than its carrying value. As a result, we concluded that no impairment to goodwill was required for our International E&P reporting unit.
Fair Values – Nonrecurring
See Note 5 and Note 11 for detail on our fair values for nonrecurring items, such as impairments.

Fair Values – Financial Instruments
Our current assets and liabilities include financial instruments, the most significant of which are receivables, the current portion of 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.

(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 June 30, 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 June 30, 2018, we were in compliance with this covenant with a debt-to-capitalization ratio of 31%.
Long-term debt
As of June 30, 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.

Notes to Consolidated Financial Statements (Unaudited)

During the first six 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 six months of 2018, we made contributions of $42 million to our funded pension plans and we expect to make additional contributions up to an estimated $23 million over the remainder of 2018.  During the first six months of 2018, we made payments of $12 million and $11 million related to unfunded pension plans and other postretirement benefit plans.

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 fourth quarter of 2017, we received notification from the U.K.’s First-tier Tribunal that the decommissioning cost deductions, which we had claimed, were not allowable. We are progressing our appeal against 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.  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

MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)

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 offset by the prices we receive for 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.

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, and total assets were $21.9 billion at June 30, 2018. During the second 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
In July we closed on the sale of non-core, non-operated conventional assets in the U.S. E&P segment, including two in the Gulf of Mexico, further concentrating and simplifying the portfolio.
We signed an agreement on the sale of our interest in the non-operated Atrush block in Kurdistan for proceeds of $56 million, and expect to close this transaction by the end of 2018 completing a full country exit.
Resource play leasing and exploration capital expenditures totaled $154 million for the quarter and $248 million for the year, which were more than fully funded through the divestiture proceeds received in the first quarter 2018.
Liquidity
At the end of the second quarter 2018, we had approximately $5.1 billion of liquidity, comprised of $1.7 billion in cash and an undrawn $3.4 billion revolving credit facility.
In the first six months of 2018 cash provided by operating activities from continuing operations increased over 50% to $1,416 million as a result of increased price realizations and increased sales volumes in our U.S. resource plays.

Financial and operational results
Total net sales volumes for the quarter increased to 419 mboed. This represents an increase in net sales volumes of 17% compared to the same quarter last year and includes an increase of over 40% from the U.S resource plays to 285 mboed.
Wells to sales for the quarter increased over 35% in the U.S. resource plays compared to the same quarter last year.
Our net income per share from continuing operations was $0.11 in the second quarter of 2018 as compared to a net loss per share of $0.18 in the same period last year. Included in net income results for the current quarter:
An increase in revenues of approximately 60% to $1,447 million compared to the same quarter last year as a result of increased price realizations and increased sales volumes in our U.S. resource plays. Notably, the current quarter increased 60% compared to the same quarter last year even with the sale of our Libyan subsidiary in 2018.
Net loss on commodity derivatives was $152 million compared to a net gain of $56 million in the same quarter last year due to the increases in current quarter index pricing as well as higher forecast long-term commodity prices.
Total costs and expenses from operations, excluding impairments, increased 9% primarily as a result of sales mix and sales volumes which increased 17% during the quarter.
Impairments of $34 million were primarily a result of anticipated sales of certain non-core proved properties in our

29


International and United States E&P segments during the quarter.
Net interest and other decreased by $21 million in the current quarter to $65 million primarily due to the reduction of total debt of approximately $1.75 billion in the second half of 2017.

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 in the first quarter of 2018. Three months ended June 30, 2017 includes net sales volumes relating to Libya of 11 mboed. Six months ended June 30, 2018 and 2017 includes net sales volumes relating to Libya of 16 mboed and 12 mboed.

United States E&P

Net sales volumes in the segment were higher in the second quarter 2018 primarily as a result of new wells to sales across all U.S. resource plays.

Eagle Ford – Our net sales volumes were 106 mboed in the second quarter of 2018 which was 6% higher compared to the prior year quarter. We continued to deliver impressive results from core Karnes County, where the six-well Karnes City NE pad delivered strong well results. We continued to generate strong cash flow in the quarter through a combination of well performance and oil realizations above WTI due to strong LLS-based pricing.
Bakken – Our net sales volumes of 82 mboed represent a 67% increase over the prior year quarter of 49 mboed. We brought 21 gross company-operated wells to sales in the second quarter 2018, twelve of which were in core Hector which delivered strong well results. We continued our efforts to uplift performance outside the Myrmidon and Hector core, with enhanced completion techniques being applied for the first time in Elk Creek with the three-well Bear Den pad achieving impressive well performance. We remain in full compliance with state gas capture requirements, and anticipate no impact to forward development plans.
Oklahoma – Our net sales volumes in the second quarter 2018 increased by 63% from the year ago quarter, with net sales volumes of 80 mboed. In the SCOOP, we brought on the four-well Woodford Lightner infill pad on 660-foot spacing across a half section, which exceeded expectations. In the STACK, four Meramec wells in the Siegrist infill pad achieved well results which met our expectations with strong oil rates. We also signed a firm transportation agreement for 100 million cubic feet per day, beginning in fourth quarter 2018, to protect near-term natural gas production and bridge to the start-up of the Midship Pipeline on which we are an anchor shipper.
Northern Delaware – Our net sales volumes were 17 mboed in the second quarter 2018. We brought 13 gross company-operated wells to sales in the Malaga area in Eddy County. Drilling efficiencies enabled us to reduce our rig count from five to four in the second quarter 2018, without changing our full-year estimate of wells to sales. In June 2018, we executed an agreement with San Mateo for water gathering and disposal in Eddy County, which will significantly reduce unit production costs. We continue to benefit from our Midland-Cushing basis swaps, with open positions that include 10,000 bopd hedged for the second half of 2018 and all of 2019, and 15,000 bopd hedged for full-year 2020, all at a discount of less than $1 to WTI . See Note 12 to the consolidated financial statements for further information.

International E&P
Net sales volumes were lower in the second quarter of 2018 compared to the second quarter of 2017 primarily due to the sale of our subsidiary 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.

Crude oil and condensate – Our production from the Alba Field is primarily condensate and generally sold in relation to the Brent crude benchmark. The Alba Plant processes the rich hydrocarbon gas which is supplied by the Alba Field under a fixed price long term contract.  The Alba Plant extracts NGL’s and secondary condensate which is sold by Alba Plant at market prices, with our share of the revenue reflected in the income from equity method investments on the consolidated statements of income.
Natural gas liquids – Wet gas is sold to Alba Plant at a fixed-price term contact resulting in realized prices not fully tracking market price.  Alba Plant extracts NGLs, which are sold at market price, with our share of income from Alba Plant being reflected in the income from equity method investments on the consolidated statements of income.
Natural gas – Dry natural gas is sold to EG Holdings and AMPCO at fixed-price long term contracts resulting in realized prices not fully tracking market price.  We derive additional value from the equity investment in our downstream gas processing units EG LNG and AMPCO that market LNG and Methanol respectively at market prices.

Net gain (loss) on commodity derivatives decreased $208 million in the second quarter of 2018 compared to the same period in 2017. We have 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 and forward curves change each period. See Note 12 to the consolidated financial statements for further information.
Marketing revenues decreased $35 million in the second 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.
Net gain on disposal of assets increased $44 million in the second quarter of 2018 primarily related to a gain on sale associated with an acreage swap in our United States E&P segment.

34



Production expenses increased $27 million in the second quarter of 2018 versus the same period in 2017 primarily due to higher sales volumes across our U.S. E&P segment. United States E&P increased $35 million primarily due to our entry into Northern Delaware late in the second quarter 2017, as well as new wells to sales across all U.S. resource plays. International E&P decreased $8 million primarily due to the timing of our U.K. liftings, which resulted in decreased sales volumes during the second quarter 2018.

Marketing costs decreased $38 million in the second 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.
Shipping, handling and other operating expenses increased $15 million in the second 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 $35 million in the second quarter of 2018. The increase in unproved property impairments is primarily due to leases that we decided not to drill or extend with near term expirations and as a result of increasing the number of leases in our portfolio through acquisition.
The following table summarizes the components of exploration expenses:

Depreciation, depletion and amortization increased $20 million in the second quarter of 2018. United States E&P DD&A expense increased by $61 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 $39 million primarily due to the timing of our U.K. liftings, which resulted in decreased sales volumes during the second quarter 2018. Our segments apply the units-of-production method to the majority of their assets, including capitalized asset retirement costs; therefore, volumes have an impact on DD&A expense.
The DD&A rate (expense per boe), which is impacted by changes in reserves, 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 second 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.

Impairments increased $34 million in the second quarter of 2018. Impairments in the second quarter of 2018 were primarily a result of anticipated sales of certain non-core proved properties in our International and United States E&P segments. See Note 5 for discussion of the divestitures in further detail.
Taxes other than income includes production, severance, and ad valorem taxes, primarily in the U.S., which tend to increase or decrease in relation to revenue and sales volumes. U.S. sales volumes and revenues increased during the second quarter of 2018, which resulted in an increase of $20 million versus the same period in 2017. This was partially offset by a reduction in the reserve for non-income tax examinations relating to open tax years. The following table summarizes the components of taxes other than income:

General and administrative increased $15 million in the second quarter of 2018 versus the same period in 2017. This was primarily the result of improved performance of stock-based performance units tied to our total shareholder return ("TSR") as compared to our peer group.
Net interest and other decreased $21 million in the second 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.
Provision (benefit) for income taxes reflects an effective tax rate from continuing operations of 31% in the second quarter of 2018, as compared to an effective tax rate of 37% in the second 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 $230 million after-tax in the second quarter of 2018 primarily due to higher price realizations and an increase in sales volumes, which resulted in increased revenue. This increase in sales volumes resulted in a corresponding increase to production expenses, DD&A, taxes other than income, and shipping, handling and other operating expenses which partially offset the increase to revenues.
International E&P segment income increased $83 million after-tax in the second quarter of 2018 primarily due to higher price realizations partially offset by a decrease in sales volumes in the U.K. and Libya. This decrease in sales volumes resulted

36



in lower production and DD&A expense. Additionally, our income tax provision decreased as a result of the sale of our Libya subsidiary in the first quarter of 2018, see Note 5 to the consolidated financial statements for further information.

Net gain (loss) on commodity derivatives decreased $391 million in the first six months of 2018 compared to the same period in 2017. We have 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 for the first six months of 2018 decreased by $69 million 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 $23 million for the first six months 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.
Net gain on disposal of assets increased $300 million for the first six months of 2018 primarily related to the gain on sale of our subsidiary Marathon Oil Libya Limited, which holds a 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 information about dispositions.
Production expenses for the first six months of 2018 increased by $91 million compared to the same period in 2017 primarily due to higher sales volumes across all U.S. resource plays. United States E&P increased $77 million primarily due to new wells to sales across all U.S. resource plays including the Northern Delaware, where we began operating late in the second quarter of 2017. International E&P increased $15 million primarily due to the timing of our U.K. liftings.

37



The first six months of 2018 production expense rate (expense per boe) was higher for International E&P due to sales volume mix within our segment and higher planned maintenance costs in E.G. due to planned maintenance activities during the first quarter 2018.

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.
Shipping, handling and other operating expenses increased $56 million in the first six months of 2018 from the comparable 2017 period, 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 $59 million in the first six months of 2018 versus the comparable 2017 period. The increase in unproved property impairments is primarily due to leases that we decided not to drill or extend with near term expirations and as a result of increasing the number of leases in our portfolio through acquisition.

Depreciation, depletion and amortization increased $54 million in the first six months of 2018 from the comparable 2017 period primarily as a result of an increase of $117 million in the United States E&P segment primarily due to higher sales volumes across all U.S. resource plays, as well as our acquisition and development of Northern Delaware in 2017. Offsetting this higher expense was a decrease of $60 million in our International E&P segment as a result of the reduction of our asset retirement obligation by over $100 million in 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.
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 DD&A rate for the United States E&P segment decreased 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 International E&P decreased with the reduction of our estimated U.K. asset retirement costs and sales volume mix changes. The following table provides DD&A rates for each segment.

Impairments in the second quarter of 2018 were primarily a result of anticipated sales of certain non-core proved properties in our International and United States E&P segments. See Note 5 for discussion of the divestitures in further detail.
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. U.S. sales volumes and revenues increased in the first six months of 2018 which resulted in an increase of $45 million versus the comparable 2017 period.

General and administrative expenses increased $18 million in the first six months of 2018 compared to the same period in 2017. This was primarily the result of improved performance of stock-based performance units tied to our total shareholder return ("TSR") as compared to our peer group.
Net interest and other decreased $54 million in the first six months 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.
Provision (benefit) for income taxes reflects an effective tax rate from continuing operations of 32% in the first six months of 2018, as compared to an effective tax rate of 59% from the comparable 2017 period. See Note 8 to the consolidated financial statements for more detail discussion concerning the rate changes.

(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 $434 million after-tax in the first six months of 2018 from the comparable 2017 period primarily due to higher price realizations and an increase in sales volumes. Partially offsetting this increase was the loss related to commodity derivative positions in the first six months of 2018, as well as increased expenses such as DD&A, production expenses and shipping, handling and other operating expenses, which increase along with sales volumes.
International E&P segment income increased $122 million after-tax in the first six months of 2018 from the comparable 2017 period primarily due to higher price realizations. This increase in revenues resulted in an increase in our income tax

provision which partially offset the increase to revenues. Additionally, DD&A expenses decreased in the first six months of 2018 as a result of lower estimated U.K. asset retirement costs as discussed above.
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, 2017, except as discussed below.
Fair Value Estimates - Goodwill
As of June 30, 2018, our consolidated balance sheet included goodwill of $98 million. Goodwill is tested for impairment on an annual basis, or between annual tests when events or changes in circumstances indicate the fair value may have been reduced below its carrying value. Goodwill is tested for impairment at the reporting unit level. Our reporting units are the same as our reporting segments, of which only International E&P includes goodwill. Our policy is to first assess the qualitative factors in order to determine whether the fair value of our International E&P reporting unit is more likely than not less than its carrying amount. Certain qualitative factors used in our evaluation include, among other things, the results of the most recent quantitative assessment of the goodwill impairment test, macroeconomic conditions; industry and market conditions (including commodity prices and cost factors); overall financial performance; and other relevant entity-specific events. If, after considering these events and circumstances we determine that it is more likely than not the fair value of the International E&P reporting unit is less than its carrying amount, the quantitative goodwill test is performed.
During the second quarter of 2018, we performed our annual impairment test of goodwill using the qualitative assessment. Our qualitative assessment considered the significant excess fair value over carrying value in our most recent step one test (second quarter 2017) and noted a general improvement in the qualitative factors described above that could have a positive or negative impact on goodwill. After assessing the totality of the qualitative factors, our assessment did not indicate that it is more likely than not that the fair value is less than its carrying value. As a result, we concluded that no impairment to goodwill was required for our International E&P reporting unit.
See Note 13 to the consolidated financial statements for further information regarding our annual goodwill impairment test.
Fair Value Estimates - Impairment Assessments of Long-Lived Assets
Due to the anticipated sales of certain non-core proved properties in our International and United States E&P segments we assessed certain non-core long-lived assets for impairment. The fair values were measured using the market approach based upon anticipated sales proceeds less costs to sell, resulting in impairments of $42 million during the first six months of 2018. See Note 11 to the consolidated financial statements for further impairment information.
Accounting Standards Not Yet Adopted
See Note 2 to the consolidated financial statements.

Cash flows generated from operating activities in the first six months of 2018 were higher as commodity prices and price realizations improved compared to the first six months of 2017. Consolidated average crude oil and condensate price realizations increased by approximately 36% during the first six months of 2018 as compared to the prior period. This increase in price realizations and net sales volumes resulted in increased cash flows generated from operating activities.
Proceeds from the disposals of assets for the first six months of 2018 are primarily from the disposal of our non-operated interest in Libya and the remaining proceeds of $750 million from the 2017 sale of our Canadian business. Proceeds from the disposal of assets for the first six months of 2017 are from the disposal 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 six months of 2018 were consistent with expectations relative to 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 second quarter of 2017 we closed the acquisition of our Northern Delaware assets for a purchase price of $1.8 billion. See Note 4 to the consolidated financial statements for further information concerning dispositions.
The Board of Directors approved a $0.05 per share dividend for the first quarter of 2018, which was paid in the second quarter of 2018. See Capital Requirements below for additional information about the second quarter dividend.

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 June 30, 2018, we had approximately $5.1 billion of liquidity consisting of $1.7 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 as of June 30, 2018 are: Standard & Poor's Ratings Services BBB- (positive); Fitch Ratings BBB (stable); and Moody's Investor Services, Inc. Ba1 (positive). 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 June 30, 2018, we had no borrowings against our revolving credit facility.
At June 30, 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.
In the second quarter of 2018, we entered into an agreement to sell a non-core property in our International E&P segment for proceeds of $56 million, before closing adjustments. We expect to close this transaction during 2018.
In the second quarter of 2018, we entered into separate agreements to sell non-core, non-operated conventional properties, primarily in the Gulf of Mexico, for combined net proceeds of $16 million, before closing adjustments. These transactions closed during July of 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 June 30, 2018, compared to 32% at December 31, 2017.

As of June 30, 2018, we plan to make contributions of up to $23 million to our funded pension plans during the remainder of 2018.
Contractual Cash Obligations
As of June 30, 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 offset by the prices we receive for our products and services, our operating results will be adversely affected.
There have been no significant changes to the environmental, health and safety matters under Item 1. Business or Item 3. Legal Proceedings in our 2017 Annual Report on Form 10-K. 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. Words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” “guidance,” “intend," “may,” “plan,” “project,” “seek,” “should,” “target,” “will,” “would” or similar words may be used to identify forward-looking statements; however, the absence of these words does not mean that the statements are not forward-looking. 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;

Item 3. Quantitative and Qualitative Disclosures About Market Risk
We are exposed to market risks in the normal course of business including commodity price risk and interest rate risk. We employ various strategies, including the use of financial derivatives to manage the risks related to commodity price fluctuations. See Note 12 and Note 13 to the consolidated financial statements for detail relating to our open commodity derivative positions, including underlying notional quantities, how they are reported in our consolidated financial statements and how their fair values are measured.
Commodity Price Risk As of June 30, 2018, we had various open commodity derivatives related to crude oil and natural gas with a net liability position of $228 million. Based on the June 30, 2018 published NYMEX WTI and Henry Hub futures prices, a hypothetical 10% change (per bbl for crude oil and per MMBtu for natural gas) impacts the fair values of our net commodity derivative liability as follows:

Interest Rate Risk At June 30, 2018 our portfolio of long-term debt is comprised of fixed-rate instruments with an outstanding balance of $5.5 billion. 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.
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, 2018.  
During the first six 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.
