Notes to Consolidated Financial Statements (Unaudited)


1. Basis of Presentation
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 20182019 Annual Report on Form 10-K. The results of operations for the second quarter and first six months of 20192020 are not necessarily indicative of the results to be expected for the full year.
As a result of the announcement to sell our U.K. business in the first quarter of 2019, we have reflected these assets and liabilities as held for sale at June 30, 2019 in the consolidated balance sheet and the consolidated statement of cash flows. The related disclosures in this report exclude these held for sale amounts, unless otherwise noted. This divestiture is discussed in further detail in Note 4.

Reclassifications
We have reclassified certain prior year amounts within operating cash flow to present it on a basis comparable with the current year’s presentation with no impact on net cash provided by operating activities.
2. Accounting Standards
Not YetRecently Adopted
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. On January 1, 2020 we adopted this standard using the modified retrospective transition method through a cumulative-effect adjustment of $12 million to retained earnings as of the beginning of the adoption period. The standard requires the use of a forward-looking “expected loss” model as opposed to the current “incurred loss” model. This standard is effectivemodel used previously. See Note 8 for us in the first quarter of 2020 and will be adoptedmore information 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.credit losses.
Recently Adopted
Lease accounting standard
In February 2016, the FASB issued a new leasing accounting standard, which modified the definition of a lease and established comprehensive accounting and financial reporting requirements for leasing arrangements. It requires lessees to recognize a lease liability and a right-of-use (“ROU”) asset for all leases, including operating leases, with a term of greater than 12 months on the balance sheet. On January 1, 2019, we adopted the new lease accounting standard using the modified retrospective method and applied to all leases that existed as of that date. It 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.
The new lease standard requires certain accounting policy decisions while also providing a number of optional practical expedients for transition accounting. Our accounting policies and the practical expedients utilized are summarized below:
Implemented an accounting policy to not recognize any right-of-use assets and lease liabilities related to short-term leases on the balance sheet.
Implemented an accounting policy to not separate the lease and nonlease components for all asset classes, except for vessels.
Elected the package of practical expedients which allows us to not reassess our prior conclusions regarding the lease identification and lease classification for contracts that commenced or expired prior to the effective date.
MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)

Elected the practical expedient pertaining to land easements which allows us to continue accounting for existing agreements under the previous accounting policies as nonlease transactions. Any modifications of existing contracts or new agreements will be assessed under the new lease accounting guidance and may become leases in the future.
As a result of the adoption, we recorded a cumulative-effect adjustment to stockholders’ equity on the date of adoption of $31 million. We continue presenting all prior comparative periods without any restatements.
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 was effective for us in the first quarter of 2019. Adoption of this standard did not have a significant impact on our consolidated results of operations, financial position or cash flows.
3. Income (loss) and Dividends per Common Share
Basic income (loss) per share is based on the weighted average number of common shares outstanding. Diluted income (loss) per share assumes exercise of stock options in all periods, provided the effect is not antidilutive. The per share calculations below exclude 7 million of stock options for each of the three and six months ended June 30, 2020 and 6 million of stock options for each of the three and six months ended June 30, 2019 and 6 million and 8 million of stock options for the three and six months ended June 30, 2018, respectively, that were antidilutive.

The contract liability primarily relates to the advance consideration received from customers for crude oil sales and processing services in the U.K. A contract asset would represent 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 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.
Changes in the contract asset (liability) balance during the period are as follows.

6. Segment Information
We have two2 reportable operating segments. Both of these segments are organized and managed based upon geographic location and the nature of the products and services offered.
United States (“U.S.United States (“U.S.”) – explores for, produces and markets crude oil and condensate, NGLs and natural gas in the United States
International (“Int’l”) – 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 makerUnited States
International (“CODM”Int’l”). – explores for, produces and markets crude oil and condensate, NGLs and natural gas outside of the United States as well as produces and markets products manufactured from natural gas, such as LNG and methanol, in Equatorial Guinea (“E.G.”)
        Segment income represents income 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, impairments of proved property, impairments,goodwill, and equity method investments, unrealized gains or losses on commodity derivative instruments, effects of pension settlement lossessettlements and curtailments, or other items (as determined by the CODM)chief operating decision maker (“CODM”)) are not allocated to operating segments.

7. 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 6.
For the three and six months ended June 30, 20192020 and 2018,2019, our effective income tax rates were as follows:
  Three Months Ended June 30, Six Months Ended June 30,

(a)
In all periods presented, we maintained our valuation allowance on our net federal deferred tax assets in the U.S.
The following items caused the effective income tax rates to be different from our U.S. statutory tax rate of 21% for 2020 and 2019:
For the three and six months ended June 30, 2020, the income tax rate was reduced below the statutory rate due to the valuation allowance on our net federal deferred tax assets in the U.S., which resulted in no federal tax benefit on the U.S. loss.
For the three and six months ended June 30, 2019, and 2018:
Income taxes for the second quartermix of 2019 were impacted by pre-tax income and foreign currency revaluation. in our international operations reduced the annual effective tax rate below the statutory tax rate. Income taxestax rates for the six months ended June 30, 2019 were also impacted by the settlement of the 2010-2011 U.S. Federal Tax Audit (“IRS Audit”) in the first quarter of 2019, resulting in a tax benefit of $126 million. Additionally, in the first quarter of 2019, we recorded a non-cash deferred tax benefit of $18 million in the U.K. related to an internal restructuring. These two items are discrete to the first six months of 2019. Excluding these discrete adjustments, the effective income tax rate for the first six months of 2019 was an expense of 13%.
Income taxesIn the first quarter of 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security Act, commonly referred to as the CARES Act.  This legislation included certain provisions which accelerate income tax refunds, and as a result, in the first quarter of 2020, long term receivable balances related to alternative minimum tax credits were classified as short term. Subsequent to June 30, 2020, we received an $89 million cash refund related to these alternative minimum tax credits and interest.
8. Credit Losses
The majority of our receivables are from purchasers of commodities or joint interest owners in properties we operate, both of which are recorded at estimated or invoiced amounts and do not bear interest. The majority of these receivables have payment terms of 30 days or less. At the end of each reporting period, we assess the collectability of our receivables and estimate the expected credit losses using historical data, current market conditions and reasonable and supportable forecasts of future economic conditions.
        We are exposed to credit losses through the receivables generated from sales of crude oil, NGLs and natural gas to our customers. When dealing with the commodity purchasers, we conduct a credit review to assess each counterparty’s ability to pay. The credit review considers our expected billing exposure, timing for payment and the counterparty’s established credit rating with the rating agencies or our internal assessment of the counterparty’s creditworthiness based on our analysis of their financial statements. Our evaluation also considers contract terms and other factors, such as country and/or political risk. A credit limit is established for each counterparty based on the outcome of this review. We may require a bank letter of credit or a prepayment to mitigate credit risk. We monitor our ongoing credit exposure through active review of counterparty balances against contract terms and due dates. The expected credit losses related to receivables with the commodity purchasers were determined using the weighted average probability of default method. We also collect revenues from our non-operated joint properties where other oil and gas exploration and production companies operate the properties and market our share of production and remit payments to us. The current expected credit losses related to these receivables were determined using the loss rate method applied to aging pools.
        We are exposed to credit losses from joint interest billings to other joint interest owners for properties we operate. For this group of receivables, the expected credit losses are determined using the loss rate method applied to aging pools. Our counterparties in this group include numerous large, mid-size and small oil and gas exploration and production companies.

MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)
Although we may have the ability to withhold future revenue disbursements to recover any non-payment of joint interest billings or require a prepayment of future costs through cash calls, our credit loss exposure with this group is more significant due to inherent ownership or billing adjustments. Also, some of our counterparties may experience liquidity problems and may not be able to meet their financial obligations to us. We expect that liquidity problems will increase in the future as a result of the recent demand and pricing decline for hydrocarbons. Our current-period provision reflects the anticipated effects caused by the recent market deterioration.

9. Inventories
As a result of the IRS Audit settlement in the first quarter of 2019, the uncertain tax positions previously established are now effectively settled. The release of the accrued uncertain tax positions resulted in a $126 million tax benefit, primarily related to the additional alternative minimum tax (“AMT”) credits, see Note 22 for further detail.

Pursuant to the Tax Sharing Agreement we entered into with Marathon Petroleum Corporation (“MPC”) in connection with the 2011 spin-off transaction, MPC agreed to indemnify us for certain liabilities. In addition to the benefit from the settlement of the IRS Audit in the first quarter of 2019, we recorded a current receivable and other income of $42 million for indemnity payments due from MPC for tax expense and interest we had previously recognized. The indemnity relates to tax and interest allocable to MPC as a result of the IRS Audit. During the second quarter of 2019, we paid the IRS and were subsequently reimbursed by MPC for settlement of their indemnity obligation.

During the first quarter of 2019, we withdrew our appeal related to the Brae area decommissioning costs in the U.K., thus the uncertain tax positions previously established are now considered effectively settled with no tax expense or benefit impact.
8.    Inventories

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.

10.11. Impairments
        During the first quarter of 2020, a global pandemic caused a substantial deterioration in the worldwide demand of hydrocarbons. The following table summarizesdecreased demand, when coupled with an oversupplied market, caused a corresponding deterioration in hydrocarbon prices. We reviewed our long-lived assets for indicators of impairment during the first quarter by conducting a sensitivity analysis of the most impactful inputs to their undiscounted cash flows, including commodity prices, capital spend and reductions in production volumes to correspond with lower capital spending. Our review concluded that the carrying amounts of our long-lived assets are recoverable; however, further deterioration or a more sustained decline of commodity prices may result in impairment charges in future periods. 

        We also reviewed our equity method investments for indicators of proved properties. Additionally, it presentsimpairment. Equity method investments are assessed for impairment whenever changes in the valuesfacts and circumstances indicate a loss in value may have occurred. When a loss in value occurs that is deemed other than temporary, the carrying value of assets, by major category, measured atthe equity method investment is written down to fair value on a nonrecurring basis in periods subsequent to their initial recognition.

2019 – During the six months ended June 30, 2019, we recorded pre-tax non-cash proved property impairments of $24 million, primarily as a result of anticipated sales proceeds for certain non-core proved properties in our United States segment and the sale of our non-operated interest in the Atrush block (Kurdistan) in our International segment. The related fair value was measured using the market approach, based upon anticipated sales proceeds less costs to sell which resulted in a Level 2 classification. See Note 4 for discussion of the divestiture in further detail.
2018– During the six months ended June 30, 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 segments.

value. Our first quarter review concluded that any potential losses in values of our equity method investments were temporary because the underlying declines in both commodity prices and demand did not materially manifest until early March. However, during the second quarter of 2020, we did recognize an impairment related to one of our equity method investees as noted in the table below.

2020– During the second quarter of 2020, the continuation of the depressed commodity prices caused us to perform a review of our equity method investments. Our review concluded that a loss of our investment value in one of our equity method investees was other than temporary. We recorded an impairment of $152 million based on the difference between our carrying value and the fair value of our investment. Our remaining investments in equity method investees did not experience losses in value that caused the fair values to be below their carrying values.
We estimated the fair value of our equity method investment using an income approach, specifically utilizing a discounted cash flow analysis. The estimated fair value was based on significant inputs not observable in the market, such as the amount of gas processed by the plant, future commodity prices, forecasted operating expenses, discount rate, and estimated cash returned to shareholders. Collectively, these inputs represent Level 3 measurements.
The impairment was recognized in income (loss) from equity method investments in our consolidated statements of income. The impairment caused us to incur a basis differential between the net book value of our investment and the amount of our underlying share of equity in the investee’s net assets. The amount of this basis differential is $126 million and will be accreted into income over the next 6.5 years, which is consistent with the remaining useful life of the investee’s primary assets.
Impairments for the six months ended June 30, 2020 also included $95 million of goodwill impairment in the International reporting unit. See Note 14 for further information.
2019– During the six months ended June 30, 2019, we recorded proved property impairments of $24 million, as a result of the anticipated sales proceeds for certain non-core proved properties in our United States segment and the sale of our non-operated interest in the Atrush block (Kurdistan) in our International segment. The related fair value was measured using the market approach, based upon anticipated sales proceeds less costs to sell which resulted in a Level 2 classification. See Note 4 for further information.

In determining our ROU assets and long-term lease liabilities, the new lease standard requires certain accounting policy decisions, while also providing a number of optional practical expedients for transition accounting. Our accounting policies and the practical expedients utilized are summarized below:
Implemented an accounting policy to not recognize any right-of-use assets and lease liabilities related to short-term leases on the balance sheet.
Implemented an accounting policy to not separate the lease and nonlease components for all asset classes, except for vessels.
Elected the package of practical expedients which allows us to not reassess our prior conclusions regarding the lease identification and lease classification for contracts that commenced or expired prior to the effective date.
Elected the practical expedient pertaining to land easements which allows us to continue accounting for existing agreements under the previous accounting policies as nonlease transactions. Any modifications of existing contracts or new agreements will be assessed under the new lease accounting guidance and may become leases in the future.

13. Leases
We enter into various lease agreements to support our operations including drilling rigs, well fracturing equipment, compressors, buildings, aircraft, vessels, vehicles and miscellaneous field equipment. We primarily act as a lessee in these transactions and all of our existing leases are classified as either short-term or long-term operating leases.
The majority of the drilling rig agreements and all of fracturing equipment agreements are classified as short-term leases based on the noncancellable period for which we have the right to use the equipment and assessment of options present in each agreement. We also incur variable lease costs under these agreements primarilySupplemental balance sheet information related to chemicals and sand used in fracturing operations or various additional on-demand equipment and labor. The lease costs associated with the drilling rigs and fracturing equipment are primarily capitalizedleases was as part of the well costs.follows:
Our long-term leases are comprised of compressors, buildings, drilling rigs, aircraft, vessels, vehicles and miscellaneous field equipment. Our lease agreements may require both fixed and variable payments; none of the variable payments are rate or index-based, therefore only fixed payments were considered for recognizing lease liabilities and ROU assets related to long-term leases. Also, based on our election not to separate the lease and nonlease components, fixed payments related to equipment, crew and other nonlease components are included in the initial measurement of lease liabilities and ROU assets for all asset classes, except for vessels. For vessels, the contractual consideration was allocated between lease and nonlease components based on estimates provided by service providers.
Our leased assets may be used in joint oil and gas operations with other working interest owners. We recognize lease liabilities and ROU assets only when we are the signatory to a contract as an operator of joint properties. Such lease liabilities and ROU assets are determined based on gross contractual obligations. As we use the leased assets for joint operations, we have the contractual right to recover the other working interest owners’ share of lease costs. As a result, our lease costs are presented on a net basis, reduced for any costs recoverable from other working interest owners. The table below presents our net lease costs as of June 30, 2019 with the majority of operating lease costs expensed as incurred, while the majority of the short-term and variable term lease costs are capitalized into property, plant and equipment.

In 2018, we signed an agreement with an owner/lessor to construct and lease a new build-to-suit office building in Houston, Texas. The new Houston office location is expected to be completed in 2021. The lessor and other participants are providing financing for up to $380 million, to fund the estimated project costs. As of June 30, 2019,2020, project costs incurred totaled approximately $50$87 million, primarily forincluding land acquisition and initial designconstruction costs. The initial lease term is five years and will commence once construction is substantially complete and the new Houston office is ready for occupancy. At the end of the initial lease term, we can negotiate to extend the lease term for an additional five years, subject to the approval of the participants; purchase the property subject to certain terms and conditions; or remarket the property to an unrelated third party. The lease contains a residual value guarantee of approximately 89% of the total acquisition and construction costs.
In June 2020, we submitted a notice to the lessor, as the construction agent, to reduce the financing capacity to $340 million to align with our revised estimate of the project costs. We expect the reduction to become effective in August 2020.

14.  Goodwill
As of December 31, 2019, our consolidated balance sheet included goodwill of $95 million in the International reporting unit. Goodwill is tested for impairment on an annual basis, or between annual tests when events or changes in circumstances indicate the fair value of a reporting unit with goodwill may have been reduced below its carrying value. During the first quarter of 2020, a global pandemic caused a substantial deterioration in the worldwide demand of hydrocarbons. This demand loss resulted in a significant decline in hydrocarbon prices. The commensurate decline in our market capitalization during the first quarter indicated that it was more likely than not that the fair value of the International reporting unit was less than its carrying value.
We estimated the fair value of our International reporting unit using a combination of market and income approaches. The market approach referenced observable inputs specific to us and our industry, such as the price of our common equity, our
18

Notes to Consolidated Financial Statements (Unaudited)
enterprise value, and valuation multiples of us and peers from the investor analyst community. The income approach utilized discounted cash flows, which were based on forecasted assumptions. Key assumptions to the income approach include future liquid hydrocarbon and natural gas pricing, estimated quantities of liquid hydrocarbons and natural gas proved and probable reserves, estimated timing of production, discount rates, future capital requirements, operating expenses and tax rates. The assumptions used in the income approach are consistent with those that management uses to make business decisions. These valuation methodologies represent Level 3 fair value measurements. Based on the results, we concluded our goodwill was fully impaired, and recorded an impairment of $95 million in the consolidated statements of income for the first quarter of 2020.

Derivatives Not Designated as Hedges
Commodity Derivatives
We have entered into multiple crude oil and natural gas derivatives indexed to the respective indices as noted in the table below, related to a portion of our forecasted United States sales through 2021. These derivatives consist of three-way collars, two-way collars, fixed price swaps, basis swaps and NYMEX roll 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 price plus the difference between the floor and the sold put price. Two-way collars only consist of a sold call (ceiling) and a purchased put (floor). These commoditycrude oil and natural gas derivatives were not designated as hedges.

Derivatives Designated as Cash Flow Hedges
During 2020, we entered into forward starting interest rate swaps with a notional amount of $500 million to hedge variations in cash flows arising from fluctuations in the London Interbank Offered Rate (“LIBOR”) benchmark interest rate related to forecasted interest payments of a future debt issuance in 2022; and an additional $300 million of notional for our future debt issuance in 2025. We expect to refinance both of the debt maturities in 2022 and 2025. The swaps will terminate on or prior to the refinancing of the debt and the final value will be reclassified from accumulated other comprehensive income into earnings with each future interest payment. Subsequent to June 30, 2020, we entered into additional forward starting interest rate swaps with a notional amount of $50 million and a weighted average rate of 0.90% to hedge variations in cash flows related to the same LIBOR interest rate for our debt due in 2025.
During 2019, we entered into forward starting interest rate swaps with a total notional amount of $320 million to hedge variations in cash flows related to the 1-month LIBOR component of future lease payments of our future Houston office. These swaps will settle monthly on the same day the lease payment is made with the first swap settlement occurring in January 2022. We expect the first lease payment to commence sometime in the period from December 2021 to May 2022. The last swap will mature on September 9, 2026. See Note 13for further details regarding the lease of the new Houston office.

Derivative instruments are recorded on a net basis in our consolidated balance sheet. See Note 13.
Commodity derivatives include three-way collars, two-way collars, fixed price swaps, basis swaps and NYMEX roll basis swaps. These instruments are measured at fair value using either a Black-Scholes or a modified Black-Scholes Model. For basis swaps and NYMEX roll 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 and two-

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.
The forward starting interest rate swaps are measured at fair value with a market approach using actionable broker quotes, which are Level 2 inputs. See Note 15 for detail on the forward starting interest rate swaps.
Fair Value Estimates - Goodwill
As of June 30, 2019, our consolidated balance sheet included goodwill of $95 million. Goodwill is testedSee Note 14 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 the International reporting unit includesdetail information relating to goodwill. Our policy is to first assess the qualitative factors in order to determine whether the fair value of our International 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 goodwill (second quarter of 2017); 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 reporting unit is less than its carrying amount, the quantitative goodwill test is performed.
During the second quarter of 2019, 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 and noted there are more positive/neutral indicators than negative. After assessing the totality of these 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 reporting unit.
Fair Values – Nonrecurring

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

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

MEGPL is a signatory to the agreements related to ourOur equity method investee, Alba Plant LLC.LLC, is also a party to some of the agreements. These agreements contain clauses that causerequire MEGPL to indemnify the owners of the Alen Unit against injury to Alba Plant LLC’s personnel and damage to or loss of Alba Plant LLC’s automobiles, as well as third party claims caused by Alba Plant and certain environmental liabilities resulting from the actions or inaction by Alba Plant LLC. Pursuant to these agreements, MEGPL agreed to indemnify third party property or events, including environmental assessments,liabilities, injury to Alba Plant LLC’s personnel, and damage to or loss of Alba Plant LLC’s automobiles. At this time, we cannot reasonably estimate this obligation as we do not have any history of prior indemnification claims, as completion of the plant modifications is not expected to finish until

Inprocess the fourththird-party Alen Unit gas required the execution of third-party guarantees by Marathon Oil Corporation in favor of the Alen Unit’s owners. Two separate guarantees were executed during the second quarter of 2017,2020; one for a maximum of $91 million pertaining to the U.K. tax authorities challengedpayment obligations of Equatorial Guinea LNG Operations, S.A. and another for a maximum of $25 million pertaining to the deductibilitypayment obligations of Alba Plant LLC.  Payment by us would be required if either of those entities fails to honor its payment obligations pursuant to the relevant agreements with the owners of the Alen Unit. Certain owners of the Alen Unit, or their affiliates, are also direct or indirect shareholders in Equatorial Guinea LNG Operations, S.A. and Alba Plant LLC. Each guarantee expires no later than December 31, 2027.  We measured these guarantees at fair value using the net present value of premium payments we expect to receive from our investees. We recorded a liability for these guarantees of $4 million as of June 30, 2020, with a corresponding receivable from our investees. Each of Equatorial Guinea LNG Operations, S.A. and Equatorial Guinea LNG Train 1, S.A. provided us with a pledge of its receivables as recourse against any payments we may make under the guaranty of Equatorial Guinea LNG Operations, S.A.’s performance.
Various groups, including the State of North Dakota and three Indian tribes represented by the Bureau of Indian Affairs, have been involved in a dispute regarding the ownership of certain Brae area decommissioning costs, whichlands underlying the Missouri River and Little Missouri River.  As a result, as of June 30, 2020, we claimedhave a $101 million current liability in suspended royalty and working interest revenue, including interest, and have a long-term receivable of $25 million for U.K. corporation tax purposes. The disputecapital and expenses.
        In December 2019, we received a Notice of Violation from the North Dakota Department of Environmental Quality and a verbal notice of enforcement in January 2020 from the North Dakota Industrial Commission, related to a release of produced water in North Dakota. In January 2020, we received a Notice of Violation from the EPA related to the timingClean Air Act. Each enforcement action will likely result in monetary sanctions in excess of the deduction and did$100,000; however, we do not dispute the general deductibility of decommissioning costs. In accordance with U.K. regulations, we paid the amount of tax and interest in question, approximately $108 million, and filed our appeal. In the first quarter of 2019, we withdrew our appeal on this matter, and the corresponding revisions to current and deferred tax liabilitiesbelieve these enforcement actions would have no cumulativea material adverse earnings impacteffect on our consolidated financial position, results of operations.

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 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 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. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites. Penalties may be imposed for noncompliance.

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 onTexas. Our strategy is to deliver competitive and improving corporate level returns by focusing our capital investment in the lower cost, higher margin U.S. resource plays: theplays (the Eagle Ford in Texas, Permianthe Bakken in New Mexico,North Dakota, STACK and SCOOP in Oklahoma and Northern Delaware in New Mexico).
        Commodity prices declined substantially in the Bakken in North Dakota.first half of 2020. While commodity prices are likely to remain volatile, we believe we can manage through this lower commodity price macro environment as our portfolio affords us the flexibility to respond to changing market conditions. Our primary focus remains on protecting our balance sheet and maintaining a strong liquidity position. We also have international operations only in Equatorial Guinea after closingbelieve our financial strength, quality portfolio, and ongoing focus on reducing our cost structure better position us to navigate during this unprecedented time.
The risks associated with COVID-19 impacted our workforce and the saleway we meet our business objectives. Due to concerns over health and safety, the vast majority of our U.K. business on July 1, 2019. Total proved reserves were 1.3 billion boe (including 21 million boecorporate workforce works remotely as we plan a process for a phased return of proved reserves foremployees to the office. Working remotely has not significantly impacted our U.K. business) at December 31, 2018,ability to maintain operations, has allowed our field offices to operate without any disruption, and total assets were $21.3 billion at June 30, 2019. Duringhas not caused us to incur significant additional expenses; however, we are unable to predict the second quarterduration or ultimate impact of 2019, we continued the focus on our strategy with simplifying and concentrating our portfolio, a strengthened balance sheet, relentless focus on costs, and profitable growth within cash flows.these measures.

Key highlights include the following:
Simplifying and concentrating our portfolio
In July 2019, we closedMaintained focus on the sale of our U.K. business for proceeds of approximately $95 million, reflecting the assumption by the buyer of: working capital and cash equivalent balances of approximately $345 million and the U.K. asset retirement obligations of $966 million.
In the second quarter of 2019, we closed on the sale our 15% non-operated interest in the Atrush block in Kurdistan for proceeds of $63 million, before closing adjustments.

Strengthened balance sheet and liquidity
Returned additional capital to shareholders by acquiring approximately 15 million common shares at a cost of $236 million, with $550 million of repurchase authorization remaining at June 30, 2019.
On July 31, 2019,At the Board of Directors authorized an extensionend of the share repurchase program, which increased the remaining share repurchase authorization to $1.5 billion.
At the end of the second quarter 2019, we had approximately $4.4 billion of liquidity, comprised of $1.0 billionin cash and an undrawn $3.4 billion revolving credit facility.
Strong financial position withsecond quarter 2020, we had approximately $3.5 billion of liquidity, comprised of an undrawn $3.0 billion revolving credit facility and $0.5 billion in cash, and no significant near-term debt maturities. We remain investment grade at all three primary credit ratingsrating agencies, with recent reviews by all three primary rating agencies.
Continued our capital discipline, with an additional reduction of our Capital Budget to $1.2 billion.
Restructured a portion of our commodity derivative portfolio during the quarter, which minimized the near-term crude downside and protected basis differentials.
Continued to opportunistically execute additional commodity derivatives to minimize the risk of price fluctuations.
In April 2020, we took broad-based cost saving measures, including temporary base salary reductions for CEO and other corporate officers through year-end, a reduction in Board of Directors compensation through year-end, and U.S. employee and contractor workforce reductions.
Temporarily suspended the quarterly dividend and share repurchases to maximize liquidity.
In early July 2020, collected an $89 million cash refund related to alternative minimum tax credits and associated interest.

Financial and operational results
TotalU.S. net sales volumes for the quarter were 437decreased by 7% to 308 mboed, including 330 mboeda 4% reduction in the U.S. resource plays. Our U.S.crude oil net sales volumes increased 13% compared to the same quarter last year.year as a result of overall lower wells to sales activity driven by the lower drilling and completions activity.
Our net incomeloss per share was $0.20$0.95 in the second quarter of 20192020 as compared to a net income per share of $0.11$0.20 in the same period last year. Included in net incomeour financial results for the current quarter:
A decrease in revenues from contracts with customers of approximately 5% to $1.4 billion, compared to the same quarter last year, primarily as a result of lower price realizations partially offset by higher net sales volumes in the current quarter.

Revenues from contracts with customers decreased $891 million compared to the same quarter last year, largely due to lower price realizations and decreased production volumes. Average crude oil price realizations decreased by 64% during the first six months of 2020 as compared to the first six month of 2019.
Despite higher sales volumes, total costs and expenses from operations decreased $34 million during the quarter compared to the same quarter last year primarily as a result of lower production expenses.
Net loss on commodity derivatives of $70 million for the second quarter of 2020, an $86 million decrease from the same period in 2019, which was a net gain of $16 million.
A non-cash impairment of an investment in one of our equity method investees of $152 million.
Net cash provided by operating activities decreased 7% as commodity price realizations decreased while net sales volumes remained flat in the first six months of 2019 versus2020 decreased to $710 million or 46% primarily as a result of lower commodity price realizations, compared to the same period last year.first six months of 2019.
The June 30, 2020 cash balance reflects a decrease of approximately $336 million from year-end, due in part to working capital changes reflecting the slowdown of 2020 capital activity.
Outlook
Capital Budget
        Earlier this year, we announced an approved 2020 Capital Budget of $2.4 billion, including $200 million to fund resource play leasing and exploration (“REx”). In light of the substantial decline in commodity prices and oversupply in the market, our Board of Directors approved a reduction to our Capital Budget earlier in the year to a level of $1.3 billion. Due to strong execution and capital efficiency improvement, in August we further reduced our full year 2020 capital spending budget to $1.2 billion. This revised Capital Budget represents a 50% reduction of our original budget. The revised budget contemplates a full suspension of our Oklahoma activity in 2020, a decrease in Northern Delaware drilling activity, and a continued optimization of our development plans in the Bakken and Eagle Ford. This also completes our REx drilling program for 2020. Additional adjustments to capital spending plans may be necessary in the future to respond to the shifts in the macro environment.

Commensurate with our revised budget of $1.2 billion for 2020, we believe our full year production volumes will be between 370 mboed to 384 mboed.

United States
Net sales volumes in the segment were higherlower in the second quarter of 2020 but higher in the first six months of 2020 as compared to their respective 2019 primarily asperiods. In the second quarter of 2020, we began the process of transitioning to a resultsignificantly lower level of newdrilling and completion activity across our domestic portfolio. This lower pace of activity had the biggest effect in Oklahoma, where we did not bring any wells to sales across all U.S. resource plays.during the quarter and experienced a significant decline in production. Overall sales volumes increased in the first six months of 2020 due to an increase in the absolute number of producing wells since June 30, 2019, primarily in the Bakken and Eagle Ford.

We expect that our planned pace of drilling and completions activity during the second half of the year will enable us to  meet our 2020 production guidance as noted in the preceding Outlook section.

Eagle Ford– Our net sales volumes were 108 mboed in the second quarter of 2020, including oil sales of 66 mbbld and we brought 20 gross company-operated wells to sales. Given the market conditions in the second quarter, we suspended frac activities. In the third quarter of 2020, we restarted our drilling program and plan to average 2 rigs and 1 frac crew over the second half of 2020.

Bakken– Our net sales volumes were 103 mboed, including 81 mbbld of oil sales and we brought 8 gross company-operated wells to sales. We suspended frac activity in the second quarter. In the third quarter of 2020, we resumed completions activities. We plan to average 2 rigs and 1 frac crew over the second half of 2020.
Oklahoma– Our net sales volumes were 60 mboed, including 16 mbbld of oil sales. During the quarter, we suspended all drilling and completions operations in Oklahoma; we do not plan to drill any additional wells in Oklahoma during 2020.

Eagle Ford– Our net sales volumes were 109 mboed in the second quarter of 2019 which was 3% higher compared to the prior year quarter. During the second quarter of 2019, we continued to deliver strong results from the expanded core of Atascosa County in terms of well performance. Additionally, we continued efforts to uplift performance outside of the Karnes and Atascosa core, by applying enhanced completion techniques in Gonzales County. Overall, despite a majority of wells to sales outside of Karnes County during second quarter, the Eagle Ford asset achieved a quarterly record for average 30 day initial well productivity, while continuing to drive a trend of lower completed well costs per lateral foot.
Bakken– Our net sales volumes of 103 mboed represent a 26% increase over the prior year quarter of 82 mboed with company-operated wells to sales balanced between Myrmidon and Hector. We continued to improve capital efficiency, which was highlighted by a six well pad in Myrmidon, with an average completed well cost of $5.3 million. The average completed well cost for all second quarter wells was just $5.2 million.
Oklahoma– Our net sales volumes in the second quarter of 2019 increased by 3% from the prior year quarter, with net sales volumes of 82 mboed. Wecontinued to deliver strong results from the over-pressured STACK where the eight-well per section Mike Stroud infill achieved average completed well costs more than 30% below the previously drilled parent well. We continued to make significant progress in reducing our cost structure with our two most recent over-pressured STACK infills completed at an average completed well cost of $6.3 million normalized to a 10,000 foot lateral.
Northern Delaware – Our net sales volumes were 27 mboed in the second quarter of 2019 which was 59% higher compared to the prior year quarter. Wecontinued to make progress in reducing our cost structure and improving margins, with second quarter cash costs down over the prior year on a per boe basis, 100% of water on pipe for all second quarter wells to sales, and a rising percentage of total oil production on pipe. Second quarter again featured strong Upper Wolfcamp productivity in Malaga, with the second quarter completed well costs per lateral foot below the 2018 average.


Northern Delaware – Our net sales volumes were 30 mboed, including 16 mbbld of oil sales and we brought 6 gross company-operated wells to sales. We suspended all drilling and completions operations during the quarter and expect to bring only a limited number of wells to sales during the remainder of the year.
International
Net sales volumes were lower in the second quarter of 20192020 compared to the second quarter of 20182019 primarily due to natural field decline in E.G. and timing of E.G liftings in theand disposition of our U.K. business.

Equatorial Guinea – Net sales volumes in the second quarter of 2019 were lower compared to the same period in 2018 as a result of natural field decline.
United Kingdom – Second quarter of 2019 net sales volumes were lower compared to the second quarter of 2018 primarily due to timing of liftings in the non-operated Foinaven complex. In July 2019, we closed on the sale of our U.K. business. See Note 4 to the consolidated financial statements for further information.
Libya – During the first quarter of 2018 we closed on the sale of our subsidiary in Libya. See Note 4 to the consolidated financial statements for further information.





Market Conditions
Crude oil and condensate and NGLs benchmarks decreased in the second quarter and first six months of 2019 as2020 were lower compared to the same period in 2018. As a result,2019 due to timing of liftings. We expect our production in the third quarter of 2020 to decline sequentially due to the impact of expected higher realized prices, which would reduce our net interest under the production sharing contract, higher third quarter facility downtime, and natural field decline.
United Kingdom – In July 2019, we experienced decreased price realizations associated with those benchmarks.closed on the sale of our U.K. business. See Note 4 to the consolidated financial statements for further information.

Market Conditions
Commodity prices are the most significant factor impacting our revenues, profitability, operating cash flows, the amount of capital we invest in our business, payment of dividends and funding of share repurchases. Commodity prices declined substantially in the first half of 2020 resulting from demand contraction related to the global pandemic and increased supply following the OPEC decision to increase production. A revised OPEC deal to reduce production was agreed early in the second quarter of 2020 and oil prices partially recovered in the latter part of the second quarter. However, given the scale of worldwide demand contraction, we expect commodity prices to remain volatile. Refer to Item 1A. Risk Factors in our 2019 Annual Report on Form 10-K for further discussion on how further declines in commodity prices could impact us.

Crude oil and condensate Alba Fieldfield liquids production is primarily condensate and generally sold in relation to the Brent crude benchmark. Alba Plant LLC processes the rich hydrocarbon gas which is supplied by the Alba Fieldfield under a fixed price long term contract. Alba Plant LLC extracts NGL’sNGLs and secondary condensate which is then sold by Alba Plant LLC at market prices, with our share of the revenue reflected in income from equity method investments on the consolidated statements of income. Alba Plant LLC delivers the processed dry natural gas to the Alba Fieldfield for distribution and sale to AMPCO and EG LNG.
Natural gas liquids Wet gas is sold to Alba Plant LLC at a fixed-price term contract resulting in realized prices not tracking market price. Alba Plant LLC extracts and keeps NGLs, which are sold at market price, with our share of income from Alba Plant LLC being reflected in the income from equity method investments on the consolidated statements of income.
Natural gas Dry natural gas, processed by Alba Plant LLC on behalf of the Alba Fieldfield is sold by the Alba Fieldfield to EG LNG and AMPCO at fixed-price long term contracts resulting in realized prices not tracking market price. We derive additional value from the equity investment in our downstream gas processing units EG LNG and AMPCO. EGLNGEG LNG sells LNG on a market-based long-term contract and AMPCO markets methanol at market prices.

Net gain (loss) on commodity derivatives In the second quarter of 20192020, the net gainloss on commodity derivatives was $16$70 million, compared to the same period in 2018,2019, which was a net lossgain of $152$16 million. We have multiple crude oil and natural gas derivative contracts that settle against various indices. We record commodity derivative gains/losses as the index pricing and forward curves change each period. See Note 1315 to the consolidated financial statements for further information.
Income from equity method investments decreased $29$183 million for the second quarter of 20192020 from the comparable 20182019 period primarily due to lower pricesan impairment of $152 million to an investment in an equity method investee, and lower sales volumes of LPG at our Alba plant, methanol at our AMPCO facility and LNG at our EGLNG production facility.


Net gain on disposal of assets decreased $58 millionin the second quarter of 2019 primarily related to gain on saleprice realizations associated with an acreage swap in our Unites States segment ininvestees. See Note 11 to the second quarter of 2018.consolidated financial statements for further information on the equity method investee impairment.
Production expenses decreased $12$64 million in the second quarter of 20192020 versus the same period in 2018. Production expenses across our United States segment decreased $6 million primarily due to reduced water hauling costs in the Northern Delaware, with all new wells on pipe in the second quarter; partially offset by increase in other resource plays due to volume. International decreased $6 million2019, primarily as a result of lower well workover and maintenance activities, lower U.S. contract labor, and the sale of our U.K. liftings,business which resulted in lower sales volumesclosed during the secondthird quarter of 2019.
The second quarter of 20192020 production expense rate (expense per boe) for United States was lower primarily due to higher sales volumes and reduced costsfor International as a result of the sale of our U.K. business which closed during the third quarter of 2019. Our U.S. production expense rate was lower as a result of the same reasons identified in the preceding paragraph in the second quarter of 2019.2020. While the production expense rates for each of our U.S. and International segments were significantly lower than the prior period, we still expect our full year production expense rates to be consistent with previously provided guidance of $4.25 - $5.25 per boe and $2.15 - $2.65 per boe, respectively.

Depreciation, depletion and amortization decreased $7$8 million in the second quarter of 2019. In our International segment, we had a decrease of $12 million2020 primarily due to lowerthe sale of our U.K. liftingsbusiness which closed during the secondthird quarter of 2019 partially offset by higher production in the U.S.2019. 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 reserves, capitalized costs and sales volumes, can also impact our DD&A expense. Our International DD&A rate decreased primarily due to timingthe sale of liftings in theour U.K. Our United States DD&A rate decreased primarily due to non-core asset dispositions in the Gulf of Mexico inbusiness which closed during the third quarter 2018 and first quarterof 2019.

Impairments decreased $16$18 million primarily as a result of impairments to certain non-core proved properties in our United States segment in the second quarter of 20192019. See Note 11 to the consolidated financial statements for more 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. Taxes other than income decreased $49 million primarily due to timing of non-core proved property dispositionslower price realizations and lower sales volumes in our International and United States segments. See Note 10 for discussion of the impairments in further detail.


General and administrative decreased$18 millionU.S. segment in the second quarter of 2019 primarily as a result of change in value of stock-based performance units tied to our total shareholder return (“TSR”) as compared to our peer group.2020.

See Note 7 to the consolidated financial statements for a more detaildetailed discussion concerning the rate changes.
Segment Income
Segment income represents income from continuing operations excludingwhich 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. GainsThese 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 of proved property, goodwill and equity method investments, unrealized gains or losses on commodity derivative instruments, effects of pension settlement losses,settlements and curtailments, or other items (as determined by the CODM) are not allocated to operating segments.

Net lossgain (loss) on commodity derivatives In the first six months of 2019,2020, the net lossgain on commodity derivatives was $75$132 million, compared to the same period in 20182019 which was a net loss of $254$75 million. We have multiple crude oil and natural gas derivative contracts that settle against various indices. We record commodity derivative gains/losses as the index pricing and forward curves change each period. SeeNote 1315 to the consolidated financial statements for further information.
Income from equity method investments decreased $55$206 million for the first six months of 2019 from the comparable 2018 period2020 primarily due to lower pricesan impairment of $152 million to an investment in an equity method investee in the second quarter of 2020 as well as lower price realizations and lower net sales volumes driven by our planned turnaroundfrom equity method investments in E.G. duringdue to the planned triennial turnaround in the first quarter 2019.of 2020.
Net gain on disposal of assets decreased $273$27 million for the first six months of 20192020 primarily as a result of the sale of our Libya subsidiary for a pre-tax gainworking interest in the Droshky field (Gulf of $255 million inMexico), which closed during the first quarter of 2018.

The indemnity relates to tax and interest allocable to MPC as a result of the closure of the IRS Audit in accordance with the Tax Sharing Agreement. See Note 7 for further detail.first quarter of 2019.
Production expenses for the first six months of 20192020 decreased by $42$91 million compared to the same period in 2018.2019. Production expense in our International segment decreased $23$64 million primarily as a result of the sale of our U.K. business, which closed during the third quarter of 2019. Production expense in our United States segment decreased $29 million primarily due to the timing of our U.K. liftings, which resulted in lower sales volumes, as well as the sale of our Libya subsidiary in the first quarter of 2018. United States decreased $18 million primarily due to non-core asset dispositions in the Gulf of Mexico during the third quarter 2018workover and due to reduced water hauling costs in the Northern Delaware, with all new wells on pipe in the second quarter.maintenance activities, and lower contract labor.
The first six months of 20192020 production expense rate (expense per boe) was lower for our United States segment due to the aforementioned reasons. Expense per boe for our International segment decreased due to change in sales volume mix, which was impacted by the timing of liftings and the sale of our Libya subsidiary in 2018.the U.K. business, which closed during the third quarter of 2019.

Exploration expenses include unproved property impairments, dry well costs, geological and geophysical, and other, which decreased $32$31 million in the first six months of 2020. Decreases in unproved property impairments were primarily driven by our decision not to drill certain leases related to resource exploration in the first quarter of 2019.

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 reserves, capitalized costs and sales volumes, can also impact our DD&A expense. The DD&A rate for International decreased primarily as a result of dispositions.

Segment Income
Segment income represents income excludingwhich excludes certain items not allocated to our operating segments, net of income taxes. AportionA portion of our corporate and operations general and administrative support costs are not allocated to the operating segments. GainsThese 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 of proved property, goodwill and equity method investments, unrealized gains or losses on commodity derivative instruments, effects of pension settlement losses,settlements and curtailments, or other items (as determined by the CODM) are not allocated to operating segments.

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, 20182019, except as discussed below.
Impairment of Equity Method Investments
In the second quarter of 2020, we recorded an impairment of $152 million to an investment in an equity method investee, which was reflected in income (loss) from equity method investments in our consolidated statements of income. Equity method investments are assessed for impairment whenever changes in the facts and circumstances indicate a loss in value may have occurred. When a loss is deemed to have occurred that is other than temporary, the carrying value of the equity method investment is written down to fair value.
Fair Value Estimates - Goodwillvalue calculated for the purpose of testing our equity method investees for impairment is estimated using the present value of expected future cash flows method. Significant judgment is involved in performing these fair value estimates since the results are based on forecasted assumptions and the performance of entities that we do not control. Significant assumptions include:
Future condensate, NGL, LNG, natural gas & methanol prices. Our estimates of future prices are based on our analysis of market supply and demand and consideration of market price indicators. Although these commodity prices may experience extreme volatility in any given year, we believe long-term industry prices are driven by global market supply and demand. To estimate supply, we consider numerous factors, including the worldwide resource base, depletion rates and OPEC production policies. We believe demand is largely driven by global economic factors, such as population and income growth, and governmental policies. The prices we use in our fair value estimates are consistent with those used in our planning and capital investment reviews. There has been significant volatility in
38


commodity prices and estimates of such future prices are inherently imprecise. See Item 1A. Risk Factors in our Form 10-K for the year ended December 31, 2019 for further discussion on commodity prices.
Estimated quantities of feedstock condensate, NGLs and natural gas processed by our investees. There are two primary sets of inputs used to estimate feedstock volumes processed by our investees. The first input involves hydrocarbons produced from our Alba Field. Our equity method investees currently process hydrocarbons from our Alba Field, which consists of condensate, NGLs and natural gas reserves. Estimated quantities of hydrocarbons processed from our Alba Field are based on a combination of proved reserves and risk-weighted probable reserves and resources such that the combined volumes represent the most likely expectation of recovery. See Item 1A. Risk Factors in our Form 10-K for the year ended December 31, 2019 for further discussion on reserves.

The second input involves our estimate of future third-party gas to be processed by our investees. Our investees have capacity to process hydrocarbons from sources other than our Alba field. During 2019, we executed agreements for processing natural gas produced from the third party-owned Alen field through the existing Alba Plant LLC LPG processing plant and the EGHoldings LNG production facility beginning in 2021. Estimated natural gas volumes processed from the Alen field were based on forecasts received from the operator of the Alen field.

Expected timing of production. Production forecasts are the outcome of engineering studies which estimate reserves, as well as expected capital programs. The actual timing of the production could be different than the projection. Cash flows realized later in the projection period are less valuable than those realized earlier due to the time value of money. The expected timing of production from the Alba Field that we use in our fair value estimates is consistent with that used in our planning and capital investment reviews. The expected timing of production from the Alen Field is consistent with forecasts received from the operator of that field.
Discount rate commensurate with the risks involved. We apply a discount rate to our expected cash flows based on a variety of factors, including market and economic conditions, operational risk, regulatory risk and political risk. A higher discount rate decreases the net present value of cash flows
We base our fair value estimates on projected financial information which we believe to be reasonably likely to occur. This includes the estimated dividends and/or return of capital we expect to be paid by our equity method investees, which are directly affected by the significant assumptions described in the preceding paragraphs. An estimate of the sensitivity to changes in assumptions in our cash flow calculations is not practicable, given the numerous other assumptions (e.g. reserves, commodity prices, operating costs, inflation and discount rates) that can materially affect our estimates. Unfavorable adjustments to some of the above listed assumptions would likely be offset by favorable adjustments in other assumptions.
SeeNote 1411 to the consolidated financial statements for further information regarding our annual goodwillthe impairment test.recognized during the second quarter of 2020.
Fair Value Estimates – Goodwill
        In the first quarter of 2020, a triggering event (significant decline in market capitalization caused by worldwide declines in hydrocarbon demand and corresponding prices) required us to assess our goodwill in the International reporting unit for impairment as of March 31, 2020. We estimated the fair value of our International reporting unit using a combination of market and income approaches and concluded that a full impairment of $95 million was required. See Note 14 to the consolidated financial statements for further information.
Estimated Quantity of Net Reserves 
Continued lower commodity prices could have a material effect on the quantity and present value of our proved reserves. To the extent that commodity prices decline further throughout 2020, a portion of our proved reserves could be deemed uneconomic and no longer classified as proved. This could impact both proved developed producing reserves as well as proved undeveloped reserves. Future reserve revisions could also result from changes to our Capital Budget and drilling plans among other things. However, any impact of lower SEC pricing will likely be partially offset by continued cost reduction efforts. Also, any volumes reclassified to unproved reserves could return to proved reserves as commodity prices improve. Any reduction in proved reserves, especially as a result of continued lower commodity prices, could result in an acceleration of future DD&A expense and impairments to long-lived assets.
Accounting Standards Not Yet Adopted
See Note 2 to the consolidated financial statements.

Cash Flows
        Commodity prices are the most significant factor impacting our revenues, profitability, operating cash flows, the amount of capital we invest in our business, payment of dividends, and funding of share repurchases. While we generated cash flows from operations during the first six months of 2020, the lower price environment reduced our cash flow generation compared to the prior year. Should lower prices continue, our ability to generate cash from operations could be negatively affected. The following table presents sources and uses of cash and cash equivalents:

Cash flows generated from operating activities in the first six months of 20192020 were 7%46% lower primarily as a result of lower commodity price realizations decreased while net sales volumes remained flat compared to 2018. Consolidated average crude oil and condensate price realizations, inclusive of the impacts of realized gains and losses on commodity derivatives, decreased by approximately 5% during the first six months of 2019 as compared to the prior period.realizations.
Proceeds from the disposals of assets for the first six months of 2019 were primarily related to the final proceeds received from the sale of non-operated interest in the Atrush block in Kurdistan. Proceeds from the disposals of assets for the first six months of 2018 were primarily related to the final proceeds received from the sale of our Canadian business and sale of our non-operated interest in Libya. See Note 4 to the consolidated financial statements for further information concerning dispositions.
Additions to property, plant and equipment in the first six months of 2019 were consistent with expectations relative to our $2.6 billion Capital Budget, which includes approximately $2.4 billion of development capital and $200 million to fund resource play leasing and exploration (“REx”).

In the first six months of 2019,2020, we acquired approximately 169 million common shares at a cost of $250$85 million, which were held as treasury stock. See Note 1618 to the consolidated financial statements for further information.


Liquidity and Capital Resources
Available Liquidity
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, 2019,2020, we had approximately $4.4$3.5 billion of liquidity consisting of $1.0$0.5 billion in cash and cash equivalents and $3.4$3.0 billion available under our revolving Credit Facility. Additionally, in early July, we collected an $89 million cash refund related to alternative minimum tax credits and associated interest. We expect cash flow from operations to improve during each of the third and fourth quarters of 2020, relative to the second quarter 2020, commensurate with an expected increase in commodity prices relative to the second quarter. See Item 1A. Risk Factors for a more detailed discussion of recent developments affecting the energy industry.

Our working capital requirements are supported by these sourcesour cash and we may issue either commercial paper backed bycash equivalents and our Credit Facility orFacility. 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, including the global pandemic, could affect our operations and our ability to access the capital markets. In

In addition, we also have the ability to borrow on our U.S. commercial paper program, which is backed by the revolving credit facility. A downgrade in our credit ratings could increase our future cost of financing or limit our ability to access capital, and could result in additional credit support requirements. See Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 20182019 for a discussion of how a further downgrade in our credit ratings could affect us.
On May 6, 2020, our Board of Directors temporarily suspended our quarterly dividend payment as we prioritize our liquidity and balance sheet.
Capital Resources
Credit Arrangements and Borrowings
At June 30, 2019,2020, we had no borrowings against our Credit Facility or under our U.S. commercial paper program that is backed by the Credit Facility.
At June 30, 2019,2020, we had $5.5 billion of total debt outstanding, with our next significant debt maturity of which $600 million is$1.0 billion due June 2020.November 2022. 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.
We continue to own $400 million of St. John the Baptist, State of Louisiana revenue refunding bonds that were originally issued in December 2017. In July, we announced that we had delivered to the trustee and remarketing agent a conditional notice of conversion of up to $400 million of the bonds to remarket them in August. Information about these bonds are available on the website of the Municipal Securities Rulemaking Board via its Electronic Municipal Market Access system at www.msrb.org. Information on that website is not incorporated by reference into this filing.
In 2018, we signed an agreement with an owner/lessor to construct and lease a new build-to-suit office building in Houston, Texas. The new Houston office location is expected to be completed in 2021. The lessor and other participants are providing financing for up to $380 million, to fund the estimated project costs. As of June 30, 2020, project costs incurred totaled approximately $87 million, including land acquisition and construction costs. In June 2020, we submitted a notice to the lessor, as the construction agent, to reduce the financing capacity to $340 million to align with our revised estimate of the project costs. We expect the reduction to become effective in August 2020.
Shelf Registration

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. 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. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites. Penalties may be imposed for noncompliance.
There have been no significant changes to the environmental, health and safety matters under Item 1. Business or Item 3. Legal Proceedings in our 20182019 Annual Report on Form 10-K. See Note 2224 to the consolidated financial statements for a description of other contingencies.

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 1315 and Note 1416 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, 2019,2020, we had various open commodity derivatives related to crude oil with a net asset position of $25 million.derivatives. Based on the June 30, 20192020 published indexNYMEX WTI and natural gas futures prices, a hypothetical 10% change (per bbl for crude oil) increases (decreases)oil, per MMbtu for gas) would change the fair values of our $79 million net commodity derivative open positions as follows:asset position to the following:
(In millions)Hypothetical Price Increase of 10%Hypothetical Price Decrease of 10%
Derivative asset - Crude Oil$57  $93  
Derivative asset (liability) - Natural Gas(4)  
Total$53  $98  
(In millions)Hypothetical Price Increase of 10% Hypothetical Price Decrease of 10%
Crude oil derivatives$(35) $37

Interest Rate Risk
At June 30, 20192020 our portfolio of current and 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.

At June 30, 2020, we had forward starting interest rate swap agreements with a total notional of $1.1 billion designated as cash flow hedges. We utilize cash flow hedges to manage our exposure to interest rate movements by utilizing interest rate swap agreements to hedge variations in cash flows related to (1) the 1-month LIBOR component of future lease payments on our future Houston office and (2) the benchmark LIBOR index for our debt due in 2022 and 2025. A hypothetical 10% change in interest rates would change the fair values of our $24 million net liability position to the following as of June 30, 2020:
(In millions)Hypothetical Interest Rate Increase of 10%Hypothetical Interest Rate Decrease of 10%
Interest rate cash flow hedges$16  $32  
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, 2019.2020.  
During the first six months of 2019,2020, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II – OTHER INFORMATION
Item 1. Legal Proceedings
There have been no significant changes to Item 3. Legal Proceedings in our 20182019 Annual Report on Form 10-K. See Note 2224 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. In addition to the other information set forth in this Quarterly Report on Form 10-Q, the reader should carefully consider the factors discussed in Item 1A. Risk Factors in our 2019 Annual Report on Form 10-K. There have been no material changes to the risk factors underfrom those listed in Item 1A. Risk Factors in our 20182019 Annual Report on Form 10-K.10-K, except as noted below.

Our business, financial conditions and results of operations have been adversely affected and may continue to be adversely affected by the recent COVID-19 global pandemic and the recent energy industry developments.
Any widespread outbreaks of contagious diseases have the potential to impact our business and operations. The recent novel coronavirus global pandemic, known as COVID-19, has had an adverse impact on our business, financial condition and results of operations and such impacts could be material. The current effects of COVID-19 include a substantial decline in demand for crude oil, condensate, NGLs, natural gas and other petroleum hydrocarbons, along with a corresponding deterioration in prices. In addition, COVID-19, combined with the resulting economic downturn could have a negative impact on our operations; impact the ability of our counterparties to perform their obligations; result in voluntary and involuntary curtailments, delays or cancellations of certain drilling activities; impair the quantity or value of our reserves; result in transportation and storage capacity restraints; cause shortages of key personnel, including employees, contractors and subcontractors; interrupt global supply chains; increase impairments and associated charges to our earnings; impact our cash on hand, uses of cash and cause a decrease to our financial flexibility and liquidity. In addition, the risks associated with COVID-19 impacted our workforce and the way we meet our business objectives. Due to concerns over health and safety, the vast majority of our corporate workforce works remotely as we plan a process to phase employees to return to the office. Working remotely has not significantly impacted our ability to maintain operations, or caused us to incur significant additional expenses; however, we are unable to predict the duration or ultimate impact of these measures.

The impacts of COVID-19 could be further exacerbated by the Organization of the Petroleum Exporting Countries (OPEC) and Russia regarding crude oil production cuts. Negotiations in April 2020 with OPEC and Russia resulted in an agreement to reduce production volumes; however, a failure to abide by these agreed upon crude oil production cuts may further destabilize the global oil market. The extent to which COVID-19 or the recent energy industry developments will impact our business and our financial results will depend on future developments, which are highly uncertain and cannot be predicted. As a result, at the time of this filing, it is not possible to predict the overall impact of COVID-19 or the recent energy industry developments on our business, liquidity, capital resources and financial results.

We may incur substantial capital expenditures and operating costs as a result of compliance with and changes in law, regulations or requirements or initiatives, including those addressing environmental, health, safety, or security or the impact of global climate change, air emissions or water management, and, as a result, our business, financial condition, results of operations and cash flows could be materially and adversely affected.

Our businesses are currently subject to numerous laws, regulations and other requirements relating to the protection of the environment, including those relating to the discharge of materials into the environment such as the flaring of natural gas, waste management, pollution prevention, greenhouse gas emissions, including carbon dioxide and methane, and the protection of endangered species as well as laws, regulations, and other requirements relating to public and employee safety and health and to facility security. Additionally, states in which we operate may: impose additional regulations legislation, or requirements, such as the proposed methane emission rules in New Mexico; begin initiatives addressing the impact of global climate change, air emissions or water management; or we may become subject to additional regulations based on questions of sovereignty between the states and Native American tribes. We have incurred and may continue to incur capital, operating and maintenance, and remediation expenditures as a result of these laws, regulations, and other requirements or initiatives that are being considered or otherwise implemented. To the extent these expenditures, as with all costs, are not ultimately reflected in the prices of our products, our operating results could be adversely affected. The specific impact of these laws, regulations, and other requirements may vary depending on a number of factors, including the age and location of operating facilities and production processes. We may also be required to make material expenditures to modify operations, install pollution control equipment, perform site clean-ups or curtail operations that could materially and adversely affect our business, financial condition, results of operations and cash flows. We may become subject to liabilities that we currently do not anticipate in
46


connection with new, amended or more stringent requirements, stricter interpretations of existing requirements or the future discovery of contamination. In addition, any failure by us to comply with existing or future laws, regulations, and other requirements could result in civil penalties or criminal fines and other enforcement actions against us.

We believe it is likely that the scientific and political attention to issues concerning the extent, causes of and responsibility for climate change will continue, with the potential for further regulations that could affect our operations. Our operations result in greenhouse gas emissions. Currently, various legislative or regulatory measures to address greenhouse gas emissions (including carbon dioxide, methane and nitrous oxides) are in various phases of review, discussion or implementation in the U.S. Internationally, the United Nations Framework Convention on Climate Change finalized an agreement among 195 nations at the 21st Conference of the Parties in Paris with an overarching goal of preventing global temperatures from rising more than 2 degrees Celsius. The agreement includes provisions that every country take some action to lower emissions, but there is no legal requirement for how or by what amount emissions should be lowered. Finalization of new legislation, regulations or international agreements in the future could result in increased costs to operate and maintain our facilities, capital expenditures to install new emission controls at our facilities, and costs to administer and manage any potential greenhouse gas emissions or carbon trading or tax programs. These costs and capital expenditures could be material. Although uncertain, these developments could increase our costs, reduce the demand for crude oil and condensate, NGLs and natural gas, and create delays in our obtaining air pollution permits for new or modified facilities.

Our operations may be adversely affected by pipeline, rail and other transportation capacity constraints.

The marketability of our production depends in part on the availability, proximity, and capacity of gathering and transportation pipeline facilities, rail cars, trucks and vessels. If any pipelines, rail cars, trucks or vessels become unavailable, we would, to the extent possible, be required to find a suitable alternative to transport our crude oil and condensate, NGLs and natural gas, which could increase the costs and/or reduce the revenues we might obtain from the sale of our production. For example, in early July, a U.S. district court ordered the Dakota Access Pipeline to halt oil flow and empty the pipeline within 30 days because the United States Army Corps of Engineers did not conduct a full Environmental Impact Statement.  Though a federal appellate court has administratively stayed the shutdown, if a shutdown occurs, we will need to use alternative means to transport approximately 10,000 bpd (on a net basis) of our Bakken oil. A shutdown could also have an impact on safety (because it would require the use of additional trucks, rail cars and personnel) and our Bakken price differentials, all of which could adversely affect the results of our operations. In addition, both the cost and availability of pipelines, rail cars, trucks, or vessels to transport our production could be adversely impacted by new and expected state or federal regulations relating to transportation of crude oil.
