Financial instruments – credit losses
        In June 2016, the FASB issued a newNo accounting standards updatewere adopted in the second quarter or first six months of 2021 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 throughhad 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 “incurred loss” model used previously. See Note 8 for more informationmaterial impact on credit losses.our consolidated financial statements.
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 4 million and 5 million of stock options for each of the three and six months ended June 30, 2021, respectively, and 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 that were antidilutive.

6.5.    Segment Information
    We have 2 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.”) – 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 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 whichthat 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,and certain unproved properties, goodwill, and equity method investments, unrealized gains or losses on commodity and interest rate derivative instruments, effects of pension settlements and curtailments or other items (as determined by the chief operating decision maker (“CODM”)) are not allocated to operating segments.

7.6.    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 65.
For the three and six months ended June 30, 20202021 and 2019,2020, our effective income tax rates were as follows:
Three Months Ended June 30,Six Months Ended June 30,
2020201920202019
Effective income tax rate(a)
%17 %%(52)%
Three Months Ended June 30,Six Months Ended June 30,
2021202020212020
Effective income tax rate38 %%15 %%
(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 theOur effective income tax rates to berate was different from our U.S. statutory tax rate of 21% for 2020 and 2019:
For the three and six months ended June 30, 2021 and 2020 as a result of the income tax rate was reduced belowmix of our U.S. and E.G. operations, including the statutory rate due to theincome mix within E.G. between equity method investees and subsidiaries. We currently have a full valuation allowance on our net federal deferred tax assets in the U.S., which resultedresults in no federal deferred tax expense or benefit on thecurrent year U.S. loss.
For the three and six months ended June 30, 2019, the mix of pre-tax income in our international operations reduced the annual effective tax rate below the statutory tax rate. Income tax 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%.
In 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.activity.
8.7.    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 termsconditions and other factors, suchdata 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.deemed appropriate.

9.8.    Inventories
    Crude oil and natural gas are recorded at weighted average cost and carried at the lower of cost or net realizable value. Supplies and other items consist principally of tubular goods and equipment which are valued at weighted average cost and reviewed periodically for obsolescence or impairment when market conditions indicate. The continued volatility and future decline in crude oil and natural gas prices could affect the value of our inventories and result in future impairments.

11. Impairments
        During the first quarter of 2020, a global pandemic caused a substantial deterioration in the worldwide demand of hydrocarbons. The decreased 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 impairment. 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 in value occurs that is deemed other than temporary, the carrying value of the equity method investment is written down to fair

2021– During the second quarter of 2021, we recorded an impairment expense of $24 million associated with two central facilities located in Eagle Ford. Decommissioning activities commenced during the quarter, which included the re-routing of existing wells.
We also recognized an incremental $22 million of impairment expense associated with an increase in the estimated future decommissioning costs of certain non-producing wells, pipelines and production facilities for previously divested offshore assets located in the Gulf of Mexico. In a prior reporting period, we recorded a $7 million liability in our consolidated balance sheet associated with these assets, thereby increasing the total recognized asset retirement obligation to $29 million as of June 30, 2021. See Note 11 and Note 23 for further information.
The combined effects of these items were recorded within the Impairments line item within our consolidated statements of income.
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. WeAs a result, 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 impairmentwhich 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 basisThis differential is $126 million and will bebeing accreted into income over the next 6.5 years, which is consistent with the remaining useful life of the investee’s primary assets.

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 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.Texas. The lessor and other participants are providing financing for up to $380$340 million to fund the estimated project costs. As of June 30, 2020,2021, project costs incurred totaled approximately $87$214 million, including land acquisition and construction 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.occupancy, which is expected to occur in the second half of 2021. 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.
14.13.  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

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.

Commodity Derivatives
We have entered into multiple crude oil, and natural gas and NGL derivatives indexed to the respective indices as noted in the table below, related to a portion of our forecasted United StatesU.S. sales through 2021.2022. 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 crude oil and natural gas derivatives were not designated as hedges.

During 2020, we entered into forward starting interest rate swaps with a notional amount of $500 million to hedge the variations in cash flows arising fromrelated to fluctuations in the London Interbank Offered Rate (“LIBOR”) benchmark interest rate related to forecasted interest payments of a future debtdebt issuance in 2022; and2022. Each respective derivative contract can be tied to an additional $300anticipated underlying dollar notional amount. During the third quarter of 2020, we de-designated these forward starting interest rate swaps previously designated as cash flow hedges. In the first quarter of 2021, the net deferred loss of $2 million of notional for our future debt issuance in 2025. We expectaccumulated other comprehensive income related to refinance both of the debt maturities in 2022 and 2025. Thethese de-designated forward starting interest rate swaps will terminate on or prior to the refinancing of the debt and the final value will bewas reclassified from accumulated other comprehensive income into earnings with each futureas an adjustment to net interest, payment. Subsequentas we fully redeemed the remainder of our outstanding 2022 notes in April 2021. Additionally, we recorded a $22 million mark-to-market loss and a $19 million mark-to-market gain within net interest to reflect the change in value of these interest rate swaps during the three and six months ended June 30, 2021, respectively.
During 2020, we entered into additional forward starting interest rate swaps with a notional amount of $50$350 million and a weighted average rate of 0.90% to hedge variations in cash flows arising from fluctuations in the LIBOR benchmark interest rate related to forecasted interest payments of a future debt issuance in 2025. The expected proceeds of the same LIBORfuture debt issuance were intended to refinance the $900 million 3.85% Senior Notes due 2025 (“2025 Notes”). During the second quarter of 2021, we de-designated these forward starting interest rate swaps previously designated as cash flow hedges because we no longer plan to refinance the 2025 Notes. In August 2021, we sent an irrevocable notice of redemption to the trustee to fully redeem the 2025 Notes. See Note 16for further details. We reclassified the $31 million cumulative gain related to these hedges from accumulated other comprehensive income into earnings as an adjustment to net interest.
In addition, during the second quarter of 2021, we de-designated $25 million of the $320 million Houston office cash flow hedges (discussed further in the Derivatives Designated as Cash Flow Hedges section below), as the construction cost budget estimate was reduced. The $1 million loss of these de-designated cash flow hedges as of June 30, 2021 was reclassified from accumulated other comprehensive income into earnings as an adjustment to net interest.

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.

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 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-

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 1514 for detail on the forward starting interest rate swaps.

See Note 1110 for detail on our fair values related to impairments.
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.
The following table summarizes financial instruments, excluding receivables, payables and derivative financial instruments, and their reported fair values by individual balance sheet line item at June 30, 20202021 and December 31, 2019.2020.

(a)Excludes debt issuance costs.
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.
17.16.    Debt
Revolving Credit Facility
On June 21, 2021, we executed the sixth amendment to our unsecured revolving credit facility (“Credit Facility”). The primary changes resulting from this amendment are (i) increasing the size of the Credit Facility from $3.0 billion to $3.1 billion, (ii) extending the maturity of the commitments of certain consenting lenders from May 28, 2023 to June 21, 2024 (with the remaining commitment of a single non-consenting lender to mature on May 28, 2023, at which time the size of the Credit Facility will be reduced to $3.0 billion) and (iii) including certain other provisions and revisions, including provisions to provide for the eventual replacement of LIBOR as a benchmark interest rate. As of June 30, 2020,2021, we had 0 borrowings against our $3.0 billion unsecured revolving credit facility (“Credit Facility”), as described below.Facility.
The Credit Facility includes a covenant requiring our total debt to total capitalization ratio not to exceed 65% as of the last day of each fiscal quarter. In the event of a default, the lenders holding more than half of the commitments may terminate the commitments under the Credit Facility and require the immediate repayment of all outstanding borrowings and the cash collateralization of all outstanding letters of credit under the Credit Facility. As of June 30, 2020,2021, we were in compliance with this covenant with a ratio of 33%24%.
Debt Redemption
On March 30, 2021, we sent an irrevocable notice of redemption to the trustee to fully redeem our outstanding $500 million 2.8% Senior Notes due 2022 (“2022 Notes”). The 2022 Notes were redeemed on April 29, 2021 and as a result of the

settlement, we incurred $19 million in costs related to a make-whole provision premium and the write off of unamortized discount and issuance costs.
Long-term debt
At June 30, 2020,2021, we had $5.5$4.9 billion of total long-term debt outstanding. On August 4, 2021, we sent an irrevocable notice of redemption to the trustee to fully redeem our outstanding with$900 million 3.85% Senior Notes due 2025 (“2025 Notes”). We intend to settle the 2025 Notes and pay the make-whole premium in early September 2021 using cash on hand. The amount we will pay related to the make-whole premium will be determined on or around August 31, 2021 based on the then current applicable Treasury Rate defined in the 2025 Notes’ Prospectus Supplement. Based on fluctuations in the applicable Treasury Rate in 2021, the amount of the make-whole premium is estimated to be approximately $85 million to $105 million. Subsequent to the redemption of the 2025 Notes, our next significant long-term debt maturity is in the amount of $1.0 billion due November 2022.

Stock-based performance unit awards
During the first six months of 2020,2021, we granted 1,038,676307,473 stock-based performance units to certaineligible officers, to bewhich are settled in shares. The grant date fair value per unit was $10.55,$18.07, as calculated using a Monte Carlo valuation model. AsAt the grant date, each unit represents the value of one share of our common stock. These units are settled in shares, and the number of shares of our common stock to be paid is based on the vesting percentage, which can be from 0 to 200% based on performance achieved during the performance period and as determined by the Compensation Committee of the Board of Directors (“Compensation Committee”). The performance goals are tied to our total shareholder return (“TSR”) as compared to TSR for a group including peer companies, the S&P Energy Index and the S&P 500 Index, which is determined by the Compensation Committee. Also, dividend equivalents accrue during the performance period and would be paid in cash following the end of the performance period based on the amount of dividends credited on shares of our common stock over the performance period multiplied by the number of units that vest.
During the first six months of 2021, we introduced a new type of stock-based performance unit award under the Marathon Oil Corporation 2019 Incentive Compensation Plan and granted 307,473 units to eligible officers, which are settled in cash.At the grant date for these new stock-based performance units, each unit represents the value of one share of our common stock. The benefit amount to be paid is based on the product of (i) the number of units granted, (ii) the vesting percentage, and (iii) the average daily closing price of our common stock during the final 30 calendar days ending on the last trading day of the

performance period, subject to the banking feature described below. The vesting percentage can range from 0 to 200%, which is based on performance achieved over a two-year performance period. The performance metric is a predetermined amount of cumulative free cash flow, as defined by the award agreement, generated by the Company over the performance period. The units have a banking feature whereby the stock price valuation and vesting percentage are fixed at no less than 50%, and then again at 100%, if achieved during the performance period. Once those milestones are reached, the vesting percentage will not fall below those banked percentage amounts even if cumulative free cash flow subsequently declines during the performance period, subject to the Compensation Committee’s discretion as described below. The second quarter fair value per unit was $27.32, as calculated by multiplying the estimated vesting percentage by our common stock’s closing stock price on June 30, 2020 there were 1,658,0882021. Also, dividend equivalents accrue during the performance period and would be paid in cash following the end of the performance period based on the amount of dividends credited on shares of our common stock over the performance period multiplied by the number of units outstanding.that vest. As set forth in the award agreement terms, the Compensation Committee retains discretion to reduce the vesting percentage and any bank values and determine free cash flow achievement for these awards.

24.23.    Commitments and Contingencies
In the second quarter of 2019, Marathon E.G. Production Limited (“MEGPL”), a consolidated and wholly-ownedwholly owned subsidiary, signed a series of agreements to process third-party Alen Unit gas through existing infrastructure located in Punta Europa, E.G. Our equity method investee, Alba Plant LLC, is also a party to some of the agreements. These agreements contain clauses that require (subject to certain limitations) 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 LLC and certain environmental liabilities resultingarising from certain hydrocarbons in the actions or inaction bycustody of Alba Plant LLC. Pursuant to these agreements, MEGPL agreed to indemnify third party property or events, including environmental 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

2021, and as such, we do not have any history ofor environmental discharge or contamination. Therefore, we have not recorded a liability with respect to these indemnities since the amount of potential future payments under these indemnification clauses is not determinable.
The agreements to process the third-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 2020; one for a maximum of approximately $91 million pertaining to the payment obligations of Equatorial Guinea LNG Operations, S.A. and another for a maximum of $25 million pertaining to the payment obligations of Alba Plant LLC. Payment by us would be required if eitherany 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 aOur liability for these guarantees ofwas approximately $4 million as of June 30, 2020,2021, 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 lands underlying the Missouri River and Little Missouri River. As a result, as of June 30, 2020,2021, we have a $101$121 million current liability in suspended royalty and working interest revenue, including interest, of which $111 million was included within accounts payable and $10 million related to accrued interest and was included within other current liabilities on our consolidated balance sheet. Additionally, we have a long-term receivable of $25$24 million for capital 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 Clean Air Act. EachThe enforcement action will likely result in monetary sanctions in excess of $100,000; however,and corrective actions yet-to-be specified and, while the ultimate outcome and impact to us cannot be predicted with certainty, we do not believe these enforcement actions wouldwill not have a material adverse effect on our consolidated financial position, results of operations or cash flow. flows.
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. In addition, we may also be

subject to retained liabilities with respect to certain divested assets by operation of law. For example, declines in commodity prices have created an environment where there is an increased risk that owners and/or operators of assets purchased from us may no longer be able to satisfy plugging or abandonment obligations that attach to those assets. In that event, due to operation of law, we may be required to assume plugging or abandonment obligations for those assets. Although we have established reserves for such liabilities, we could be required to accrue additional amounts in the future and these amounts could be material. For instance, as the result of the declaration of bankruptcy by a third party to which we previously divested certain offshore assets, in the second quarter of 2021 we increased our existing reserve to $29 million related to the anticipated cost to decommission certain wells, pipelines and production facilities divested to such third party. We no longer own these assets nor are they related to our current operations.
Marathon Oil has been named in various lawsuits alleging royalty underpayments in our domestic operations, and plaintiffs in some of these lawsuits are seeking class certification. We intend to vigorously defend ourselves against such claims. Although we have accrued for potential liabilities associated with these lawsuits, those accruals are based on currently available information and involve elements of judgment and significant uncertainties. Accordingly, actual losses may exceed our accruals or we could be required to accrue additional amounts in the future and these amounts could be material.
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.
At June 30, 2021, accrued liabilities for remediation relating to environmental laws and regulations were not material. It is not presently possible to estimate the ultimate amount of all remediation cost that might be incurred or the penalties that may be imposed.

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. Our strategy is to deliver competitive and improving corporate level returns by focusing our capital investment in theour lower cost, higher margin U.S. resource plays (the Eagle(Eagle Ford in Texas, the Bakken in North Dakota, STACK and SCOOP in Oklahoma and Northern Delaware in New Mexico).
        Commodity prices declined substantially in the first half Our reinvestment rate and capital allocation framework prioritizes free cash flow generation across a wide range of 2020. While commodity prices are likely to remain volatile, we believe we can manage through this lower commodity price macro environment asmake available significant cash flow for investor-friendly purposes, including return of capital to shareholders and balance sheet enhancement. Keeping our portfolio affords us the flexibility to respond to changing market conditions. Our primary focus remains onworkforce safe, minimizing our environmental impact, strong corporate governance and protecting our balance sheet and maintaining a strong liquidity position. We believe our financial strength, quality portfolio, and ongoing focus on reducing our cost structure better position usare foundational to navigate during this unprecedented time.
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 majorityexecution of our corporatestrategy.
Throughout the COVID-19 pandemic, we leveraged our emergency response protocols and business continuity plans to help manage our operations and workforce. Our workforce worksworked remotely as we planfor a significant period of time since the pandemic began. We implemented a process for a phased return of employees to the office last year and, during April 2021, the majority of our corporate workforce returned to the office. Working remotely hasdid not significantly impactedimpact our ability to maintain operations, has allowed our field offices to operate without any disruption and hasdid not causedcause us to incur significant additional expenses; however, we are unable to predict the duration or ultimate impact of these measures.expenses.

Key highlights include the following:
Maintained focus on balance sheet and liquidity
At the end of the second quarter 2020,2021, we had approximately $3.5$4.1 billion of liquidity, comprised of an undrawn $3.0$3.1 billion revolving credit facility and $0.5 billion$970 million in cash, and no significant near-term debt maturities.cash. We remainremain investment grade at all three primary rating agencies, with recent reviews by all three primaryMoody’s and Fitch recently upgrading their rating agencies.outlooks to stable and positive, respectively.
ContinuedIn the first six months of 2021, we generated $1.3 billion of cash provided by operating activities, which was more than sufficient to fund our full redemption of our $500 million 2022 Notes, additions to property, plant and equipment of $483 million and dividends of $55 million.
The June 30, 2021 cash balance reflects an increase of approximately $228 million from year-end, primarily due to higher commodity price realizations and continued capital discipline. Our U.S. segment average realized prices for crude oil and condensate, NGLs and natural gas for the six months ended June 30, 2021 were $60.08 per bbl, $24.06 per bbl and $4.43 per mcf, respectively.
We continued our capital discipline with an additional reduction ofthrough the second quarter and are within our Capital Budget to $1.2of $1.0 billion.
Restructured a portionConsistent with our strategy to enhance the balance sheet, in August 2021, we sent an irrevocable notice of redemption to the trustee to fully redeem our commodity derivative portfolio duringoutstanding $900 million 3.85% Senior Notes due 2025. See Note 16to the quarter, which minimized the near-term crude downsideconsolidated financial statements and protected basis differentials.
Continued to opportunistically execute additional commodity derivatives to minimize the risk of price fluctuations.
Liquidity and Capital ResourcesIn 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.

Outlook
Capital Budget
        Earlier this year,In February 2021, we announced an approved 2020a 2021 Capital Budget of $2.4$1.0 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 approvedwhich is effectively a reduction to ourmaintenance Capital Budget. We expect this maintenance-level Capital Budget earlierwill allow us to keep total company oil production in the year to a level of $1.3 billion. Due to strong execution and capital efficiency improvement, in August we further reduced2021 consistent with our full yearfourth quarter 2020 capital spending budget to $1.2 billion. This revisedexit rate. Our 2021 Capital Budget represents a 50% reduction ofis consistent with our original budget. capital allocation framework that prioritizes corporate returns and free cash flow generation over production growth.
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 in2021 Capital Budget is weighted towards 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 respondfour U.S. resource plays with approximately 90% allocated 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.Eagle Ford and Bakken.

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.

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.

Equatorial Guinea – Net sales volumes in the second quarter and the first six months of 20202021 were lower compared to the same period in 20192020 primarily 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,fewer liftings and natural field decline.
United Kingdom – In July 2019, we 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, redemption of our debt, 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 early second quarter of 2020 and oil prices partially recovered inthrough the latter partend of the second quarter. However, givenyear. Beginning in December 2020 and continuing through the scalefirst six months of 2021, commodity prices continued to increase due to rising oil demand as COVID-19 vaccination rates and global economic activity increased. This was also supported by ongoing petroleum supply limitations by OPEC. Extreme winter weather in February 2021 also put upward pressure on natural gas prices during the first quarter of 2021. We continue to expect commodity price volatility as a result of the continuing impact of COVID-19 on worldwide demand, contraction, we expect commodity pricesthe uneven pace of global economic recovery and OPEC supply policy. Refer to remain volatile. Refer to ItemItem 1A. Risk Factors in our 20192020 Annual Report on Form 10-K for further discussion on how further declines in commodity prices could impact us.

Crude oil and condensate Alba field 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 field under a fixed price long term contract. Alba Plant LLC extracts NGLs 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 field 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 field is sold by the Alba field 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. EG LNG sells LNG on a market-based long-term contract and AMPCO markets methanol at market prices.

Segment Income
Segment income represents income whichthat 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,and certain unproved properties, goodwill and equity method investments, unrealized gains or losses on commodity and interest rate derivative instruments, effects of pension settlements and curtailments or other items (as determined by the CODM) are not allocated to operating segments.

We recognized an impairment of $152 million related 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 from equity method investments in E.G. due to the planned triennial turnaround in the first quarter of 2020.
Net gain on disposal of assetsdecreased $27 million for the first six months of 2020 primarily as a result of the sale of our working interest in the Droshky field (Gulf of Mexico), which closed during the first quarter of 2019.
Other incomedecreased $35 million2020. Additionally, we experienced higher price realizations in the first six months of 2020 primarily due to income recognized in 2019 arising from indemnification payments received from Marathon Petroleum Corporation (“MPC”). Pursuant to the Tax Sharing Agreement we entered into with MPC, in connection with the 2011 spin-off transaction, MPC agreed to indemnify us for certain liabilities. The indemnity relates to tax and interest allocable to MPC as a result of the closure of the IRS Audit in the first quarter of 2019.2021.
Production expenses for the first six months of 20202021 decreased by $91$42 million compared to the same period in 2019.

Segment Income
Segment income represents income whichthat 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,and certain unproved properties, goodwill and equity method investments, unrealized gains or losses on commodity and interest rate derivative instruments, effects of pension settlements and curtailments or other items (as determined by the CODM) are not allocated to operating segments.
The following table reconciles segment income (loss) to net income (loss):

This increase was primarily as a result of lower crudedue to higher price realizations and higherlower DD&A due to higher net sales volumes, which wasexpenses. These favorable changes were partially offset by lower production taxes,sales volumes, realized losses on commodity derivatives (as compared to realized gains in the prior period), and higher shipping and handling expense, and production expense.

Critical Accounting Estimates 
There have been no material changes or developments in the evaluation of the accounting estimates and the underlying assumptions or methodologies pertaining to our Critical Accounting Estimates disclosed in our Form 10-K for the year ended December 31, 2019, 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 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 11 to the consolidated financial statements for further information regarding the impairment 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

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, principal debt repayments, payment of dividends and funding of share repurchases. While we generated cash flows from operationsAs commodity prices increased during the first six months of 2020, the lower price environment reduced our2021, we generated positive cash flow generation comparedfrom operations. We continue to the prior year.

Cash flows generated from operating activities in the first six months of 20202021 were 46% lower80% higher compared to the same period in 2020, primarily as a result of higher realized commodity prices. These were partially offset by net realized losses on commodity derivatives (compared to realized gains in the prior period), lower commodity price realizations.production volumes, and increased working capital usage.

The decline in our capital expenditures for the U.S. segment in the first six months of 2021 compared to the same period in 2020, was caused by lower drilling and completions activities across all four of our shale basins.

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, 2020,2021, we had approximately $3.5$4.1 billion of liquidity consisting of $0.5 billion$970 million in cash and cash equivalents and $3.0$3.1 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 our cash and cash equivalents and our Credit Facility. 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, defined benefit plan contributions, repayment of debt maturities, dividends 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.
During the first half of 2020, commodity prices significantly declined due to the combined impacts of global crude oil oversupply and lower demand for hydrocarbons due to the global pandemic. As a result, credit rating agencies reviewed many companies in the industry, including us. We continue to be rated investment grade at all three primary credit rating agencies. 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, 2019 for a discussion of how a 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.

Credit Arrangements and Borrowings
At June 30, 2020, we had no borrowings against our Credit Facility. At June 30, 2020, we had $5.5 billion of total debt outstanding, with our next significant debt maturity of $1.0 billion due 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. See Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2020 for a discussion of how a downgrade in our credit ratings could affect us.
On July 28, 2021, our Board of Directors approved a dividend of $0.05 per share payable September 10, 2021 to stockholders of record at the close of business on August 18, 2021.

Credit Arrangements and Borrowings
We continueIn June 2021, we executed the sixth amendment to own $400 millionour unsecured Credit Facility. The primary changes resulting from this amendment are (i) increasing the size of St. John the Baptist, StateCredit Facility from $3.0 billion to $3.1 billion, (ii) extending the maturity of Louisiana revenue refunding bonds that were originally issued in December 2017. In July, we announced thatthe commitments of certain consenting lenders from May 2023 to June 2024 (with the remaining commitment of a single non-consenting lender to mature on May 28, 2023, at which time the size of the Credit Facility will be reduced to $3.0 billion) and (iii) including certain other provisions and revisions, including provisions to provide for the eventual replacement of LIBOR as a benchmark interest rate. See Note 16 to the consolidated financial statements for further information.
At June 30, 2021, we had deliveredno borrowings against our Credit Facility and $4.9 billion of total long-term debt outstanding. In April 2021, we fully redeemed our outstanding $500 million 2.8% Senior Notes due 2022 and the redemption reduced annual cash interest expense by $14 million. As a result of the redemption, we incurred $19 million in costs related to a make-whole provision premium and the write off of unamortized discount and issuance costs in the second quarter of 2021. In August 2021, we sent an irrevocable notice of redemption to the trustee to fully redeem our outstanding $900 million 3.85% 2025 Notes. We intend to settle the 2025 Notes and remarketing agent a conditional notice of conversion of uppay the make-whole premium in September 2021 using cash on hand. The redemption will reduce annual cash interest expense by approximately $35 million. See Note 16 for further details related to $400 millionthis redemption. Subsequent to the redemption of the bonds2025 Notes, our next significant long-term debt maturity is in the amount of $1.0 billion due 2027. Refer to remarket them in August.

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$340 million to fund the estimated project costs. As of June 30, 2020,2021, project costs incurred totaled approximately $87$214 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
We have a universal shelf registration statement filed with the SEC under which we, as a “well-known seasoned issuer” for purposes of SEC rules, have the ability to issue and sell an indeterminate amount of various types of debt and equity securities. 
Debt-To-Capital Ratio
The Credit Facility includes a covenant requiring that our total debt to total capitalization ratio not exceed 65% as of the last day of the fiscal quarter. Our ratio was 33%24% and 31%26% at June 30, 20202021 and at December 31, 2019, respectively.2020.

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.

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 1514 and Note 1615 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, 2020,2021, we had various open commodity derivatives. Based on the June 30, 20202021 published NYMEX WTI, natural gas and natural gas liquids futures prices, a hypothetical 10% change (per bbl for crude oil, per MMbtu for gas)gas and per bbl for NGL) would change the fair values of our $79 million net asset positioncommodity derivative positions to the following:

Interest Rate Risk
At June 30, 20202021, our portfolio of current and long-term debt is comprised of fixed-rate instruments with an outstanding balance of $5.5$4.9 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, 2020,2021, we had forward starting interest rate swap agreements with a total notional amount of $1.1 billion$295 million designated as cash flow hedges and $875 million not designated as 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.office.

Part II – OTHER INFORMATION
Item 1. Legal Proceedings
In January 2020, we received a Notice of Violation from the EPA related to the Clean Air Act. The enforcement action will likely result in monetary sanctions and corrective actions yet-to-be specified and while the ultimate outcome and impact to us cannot be predicted with certainty, we believe these enforcement actions will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.
ThereMarathon Oil has been named in various lawsuits alleging royalty underpayments in our domestic operations, and plaintiffs in some of these lawsuits are seeking class certification. We intend to vigorously defend ourselves against such claims. Although we have accrued for potential liabilities associated with these lawsuits, those accruals are based on currently available information and involve elements of judgment and significant uncertainties. Accordingly, actual losses may exceed our accruals or we could be required to accrue additional amounts in the future and these amounts could be material.
Other than the items set forth above, there have been no significant changes to Item 3. Legal Proceedings in our 20192020 Annual Report on Form 10-K.

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 20192020 Annual Report on Form 10-K. There have been no material changes to the risk factors from those listed in Item 1A. Risk Factors in our 20192020 Annual Report on Form 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

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.10-K.
