MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)

1.    Basis of Presentation
These consolidated financial statements are unaudited; however, in the opinion of management, these statements reflect all adjustments necessary for a fair statement of the results for the periods reported. All such adjustments are of a normal recurring nature unless disclosed otherwise. These consolidated financial statements, including notes, have been prepared in accordance with the applicable rules of the SEC and do not include all of the information and disclosures required by U.S. GAAP for complete financial statements.
These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2020 Annual Report on Form 10-K. The results of operations for the second quarter and first six months of 2021 are not necessarily indicative of the results to be expected for the full year.
2.    Accounting Standards
No accounting standards were adopted in the second quarter or first six months of 2021 that had a material impact on 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 that were antidilutive.

4.    Revenues

As of June 30, 2021 and December 31, 2020, receivables from contracts with customers, included in receivables, less reserves were $841 million and $572 million, respectively.
The following tables present our revenues from contracts with customers disaggregated by product type and geographic areas for the three and six months ended June 30 as follows:

5.    Segment Information
    We have two reportable operating segments. Both of these segments are organized and managed based upon geographic location and the nature of the products and services 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 that 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 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.

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 5.
For the three and six months ended June 30, 2021 and 2020, our effective income tax rates were as follows:
Three Months Ended June 30, Six Months Ended June 30,
2021 2020 2021 2020
Effective income tax rate 38  % % 15  % %
Our effective income tax rate was different from our U.S. statutory tax rate of 21% for the three and six months ended June 30, 2021 and 2020 as a result of the income mix of our U.S. and E.G. operations, including the income mix within E.G. between equity method investees and subsidiaries. We currently have a full valuation allowance on net federal deferred tax assets in the U.S., which results in no federal deferred tax expense or benefit on current year U.S. activity.
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, reasonable and supportable forecasts of future economic conditions and other data as deemed appropriate.
Changes in the allowance for doubtful accounts balance were as follows:

(a)As of December 31, 2020, the current period provision consisted of $10 million in joint interest receivables and $12 million in trade receivables.
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.

As of June 30, 2021 and December 31, 2020, we had $158 million and $98 million, respectively, of exploratory well costs capitalized greater than one year related to suspended wells. Management believes these wells exhibit sufficient quantities of hydrocarbons to justify potential development. The vast majority of the suspended wells require completion activities and installation of infrastructure in order to classify the reserves as proved.

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. As a result, we recorded an impairment of $152 million, which 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. This differential is being accreted into income over the remaining useful life of the investee’s primary assets.

Additionally, impairments for the first six months of 2020 included $95 million of goodwill impairment in the International reporting unit. See Note 13 for further information.
11.    Asset Retirement Obligations
Asset retirement obligations primarily consist of estimated costs to remove, dismantle and restore land or seabed at the end of oil and gas production operations. Changes in asset retirement obligations were as follows:

In the second quarter of 2021, we had a revision of estimate of $29 million related to anticipated costs for decommissioning certain wells, pipelines and production facilities for previously divested offshore non-producing long-lived assets located in the Gulf of Mexico. As of June 30, 2021, $14 million of this revision of estimate was classified as short-term. See Note 23 for further information. During the quarter, we recognized $22 million of impairment expense associated with these non-producing long-lived assets within our consolidated statement of operations. See Note 10 for further information.
12. 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 the majority of our existing leases are classified as either short-term or long-term operating leases.

    Our wholly owned subsidiary, Marathon E.G. Production Limited, is a lessor for residential housing in E.G., which is occupied by EGHoldings, a related party equity method investee see Note 22. The lease was classified as an operating lease and expires in 2024, with a lessee option to extend through 2034. Lease payments are fixed for the entire duration of the agreement at approximately $6 million per year. Our lease income is reported in other income in our consolidated statements of income for all periods presented. The undiscounted cash flows to be received under this lease agreement are summarized below.

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 lessor and other participants are providing financing for up to $340 million to fund the estimated project costs. As of June 30, 2021, project costs incurred totaled approximately $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, 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.
13.  Goodwill
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. The commensurate decline in our market capitalization 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 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. 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. This represented the entirety of our goodwill on our consolidated balance sheet.
14.  Derivatives
For further information regarding the fair value measurement of derivative instruments, see Note 15. All of our commodity derivatives are subject to enforceable master netting arrangements or similar agreements under which we report net amounts.

Commodity Derivatives
We have entered into multiple crude oil, natural gas and NGL derivatives indexed to the respective indices as noted in the table below, related to a portion of our forecasted U.S. sales through 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).

During the second quarter and first six months of 2020, net cash received for settled derivative positions was $78 million and $91 million, respectively.
Interest Rate Swaps
During 2020, we entered into forward starting interest rate swaps to hedge the variations in cash flows related to fluctuations in the London Interbank Offered Rate (“LIBOR”) benchmark interest rate related to forecasted interest payments of a future debt issuance in 2022. Each respective derivative contract can be tied to an anticipated 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 in accumulated other comprehensive income related to these de-designated forward starting interest rate swaps was reclassified from accumulated other comprehensive income into earnings as an adjustment to net interest, as 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 forward starting interest rate swaps with a notional amount of $350 million 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 future 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 16 for 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.

Derivatives Designated as Cash Flow Hedges
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. During the second quarter of 2021, we de-designated $25 million of these hedges as the construction cost budget estimate associated with the project was reduced. The last swap will mature in September 2026. As of June 30, 2021, amounts expected to be reclassified from accumulated other comprehensive income over the next twelve months were not material. See Note 12 for further details regarding the lease of the new Houston office.

(a)Commodity derivative instruments are recorded on a net basis in our consolidated balance sheet. See Note 14.
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-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 14 for detail on the forward starting interest rate swaps.

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, 2021 and December 31, 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.
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, 2021, we had no borrowings against our Credit 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, 2021, we were in compliance with this covenant with a ratio of 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
21

MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)
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, 2021, we had $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 $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 2027. Refer to our 2020 Annual Report on Form 10-K for a listing of our long-term debt maturities.
17.    Stockholders’ Equity
No share repurchases were made under our share repurchases program during the six months ended June 30, 2021; however, we repurchased $9 million of shares during the first quarter related to our tax withholding obligation associated with the vesting of employee restricted stock awards. The total remaining share repurchase authorization was $1.3 billion at June 30, 2021. Purchases under the program are made at our discretion and may be in either open market transactions, including block purchases, or in privately negotiated transactions using cash on hand, cash generated from operations, or proceeds from potential asset sales. This program may be changed based upon our financial condition or changes in market conditions and is subject to termination prior to completion.

Stock-based performance unit awards
During the first six months of 2021, we granted 307,473 stock-based performance units to eligible officers, which are settled in shares. The grant date fair value per unit was $18.07, as calculated using a Monte Carlo valuation model. At 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 zero 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 zero 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, 2021. 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. 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.

23.    Commitments and Contingencies
In the second quarter of 2019, Marathon E.G. Production Limited (“MEGPL”), a consolidated and wholly 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 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 arising from certain hydrocarbons in the custody of Alba Plant LLC. At this time, we cannot reasonably estimate this obligation as we do not have any history of prior indemnification claims or 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 any 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. Our liability for these guarantees was approximately $4 million as of June 30, 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, 2021, we have a $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 $24 million for capital and expenses.
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.
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
25

MARATHON OIL CORPORATION
Notes to Consolidated Financial Statements (Unaudited)
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.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations 
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 our lower cost, higher margin U.S. resource plays (Eagle Ford in Texas, Bakken in North Dakota, STACK and SCOOP in Oklahoma and Northern Delaware in New Mexico). Our reinvestment rate and capital allocation framework prioritizes free cash flow generation across a wide range of commodity prices to make available significant cash flow for investor-friendly purposes, including return of capital to shareholders and balance sheet enhancement. Keeping our workforce safe, minimizing our environmental impact, strong corporate governance and protecting our balance sheet are foundational to the execution of our strategy.
Throughout the COVID-19 pandemic, we leveraged our emergency response protocols and business continuity plans to help manage our operations and workforce. Our workforce worked remotely for 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 did not significantly impact our ability to maintain operations, allowed our field offices to operate without any disruption and did not cause us to incur significant additional expenses.

Key highlights include the following:
Maintained focus on balance sheet and liquidity
At the end of the second quarter 2021, we had approximately $4.1 billion of liquidity, comprised of an undrawn $3.1 billion revolving credit facility and $970 million in cash. We remain investment grade at all three primary rating agencies, with Moody’s and Fitch recently upgrading their rating outlooks to stable and positive, respectively.
In 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 through the second quarter and are within our Capital Budget of $1.0 billion.
Consistent 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 outstanding $900 million 3.85% Senior Notes due 2025. See Note 16 to the consolidated financial statements and Liquidity and Capital Resources for further information.
Financial and operational results
In the second quarter of 2021, U.S. net sales volumes decreased by 8% to 283 mboed, including a 13% reduction in
27


U.S. crude oil net sales volumes compared to the same quarter last year as a result of overall lower drilling and completion activities and natural decline.
Our net income per share was $0.02 in the second quarter of 2021 as compared to a net loss per share of $0.95 in the same period last year. Included in our financial results for the current quarter:
Revenues from contracts with customers increased $764 million compared to the same quarter last year. We experienced significant increases in realized prices for both crude oil and condensate, NGLs and natural gas.
Net loss on commodity derivatives of $166 million, as compared to a net loss of $70 million in 2020. The increase in derivative losses were a direct result of higher commodity prices.
Income from equity method investments of $49 million, an increase of $201 million from the same period in 2020. The current quarter included higher price realizations whereas the same period in 2020 included impairments of $152 million.
Lower depreciation, depletion and amortization expenses of $65 million, primarily a result of lower production.
Compensation and ESG Highlights and Initiatives
CEO and Board of Director total compensation reduced by approximately 25% with Board compensation mix shifted more toward equity and CEO mix further aligned with broader industry norms (exclusive of temporary reductions announced in 2020).
Short-term incentive scorecard for compensation updated to focus on safety, environmental performance, capital efficiency, capital discipline/free cash flow generation and financial/balance sheet strength.
Added a 2021 GHG emissions intensity target to short-term incentive scorecard.
Adopted a medium-term goal for GHG emissions intensity reduction by 2025.
Continued Board of Director refreshment with two Directors added during the first quarter of 2021, reflecting commitment to refreshment, independence, and diversity.
Outlook
Capital Budget
In February 2021, we announced a 2021 Capital Budget of $1.0 billion, which is effectively a maintenance Capital Budget. We expect this maintenance-level Capital Budget will allow us to keep total company oil production in 2021 consistent with our fourth quarter 2020 exit rate. Our 2021 Capital Budget is consistent with our capital allocation framework that prioritizes corporate returns and free cash flow generation over production growth.
The 2021 Capital Budget is weighted towards the four U.S. resource plays with approximately 90% allocated to the Eagle Ford and Bakken.
Operations
    The following table presents a summary of our sales volumes for each of our segments. Refer to the Results of Operations section for a price-volume analysis for each of the segments.

United States
Net sales volumes in the segment were lower in the second quarter of 2021 and the first six months of 2021 as compared to their respective 2020 periods with lower capital investment resulting in fewer wells to sales year to date, coupled with natural decline. The decrease in capital investment is a direct result of the demand contraction, beginning in 2020, related to the global pandemic.
We continue to expect that our planned pace of drilling and completions activity during the remainder of the year will enable us to meet our 2021 production guidance as noted in the preceding Outlook section.

International
Net sales volumes were lower in the second quarter of 2021 and the first six months of 2021 as compared to their respective 2020 periods primarily due to fewer E.G. liftings due to natural decline.

Equatorial Guinea – Net sales volumes in the second quarter and the first six months of 2021 were lower compared to the same period in 2020 primarily due to fewer liftings and natural decline.

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 in the early second quarter of 2020 and prices partially recovered through the end of the year. Beginning in December 2020 and continuing through the first 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, the uneven pace of global economic recovery and OPEC supply policy. Refer to Item 1A. Risk Factors in our 2020 Annual Report on Form 10-K for further discussion on how declines in commodity prices could impact us.

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.

Net gain (loss) on commodity derivatives in the second quarter of 2021, was a loss of $166 million, compared to a net loss of $70 million for the same period in 2020. We have multiple crude oil, natural gas and NGL 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 14 to the consolidated financial statements for further information.
Income from equity method investments increased $201 million in second quarter of 2021 primarily due to impairments of $152 million to an investment in an equity method investee in second quarter of 2020 coupled with higher price realizations.
Production expenses decreased $3 million in the second quarter of 2021 versus the same period in 2020. Our U.S. segment production expense rate increased due to fewer wells to sales and natural decline. International segment production expense rate increased due to fewer liftings and natural decline.
The following table provides production expense and production expense rates (expense per boe) for each segment:

International $ 13  $ 15  (13) % $ 2.17  $ 1.88  15  %
Shipping, handling and other operating increased $62 million in the second quarter of 2021 versus the same period in 2020. As disclosed in our Form 10-K, certain of our processing arrangements with midstream entities are percentage-of-proceeds contracts. We classify the proceeds retained by the midstream companies as shipping and handling cost. The increase in shipping and handling costs of these percentage-of-proceeds contracts coincides with the increase in realized natural gas liquids prices.
Exploration expenses include unproved property impairments, dry well costs, geological and geophysical, and other costs. The increase in unproved property impairments were primarily driven by our decision not to drill certain leases related to resource exploration in the second quarter of 2021.
The following table summarizes the components of exploration expenses:

Depreciation, depletion and amortization decreased $65 million in the second quarter of 2021 as a result of lower sales volumes in our U.S. and International segments. Our segments apply the units-of-production method to the majority of their assets, including capitalized asset retirement costs; therefore volumes have an impact on DD&A expense.
The DD&A rate (expense per boe) is impacted by field-level changes in reserves, capitalized costs and sales volume mix between fields. The following table provides DD&A expense and DD&A expense rates for each segment:
Three Months Ended June 30,
($ in millions; rate in $ per boe) 2021 2020 Increase (Decrease) 2021 2020 Increase (Decrease)

International $ 18  $ 22  (18) % $ 3.08  $ 2.86  %
Impairments increased $46 million in the second quarter of 2021 due to a $24 million impairment as we decommissioned certain Eagle Ford central facilities and a $22 million impairment related to 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. See Note 10, Note 11, and Note 23 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 increased $44 million primarily due to higher price realizations in the U.S. segment in the second quarter of 2021.
General and administrative expenses decreased $20 million in the second quarter of 2021 as a result of cost savings realized from workforce reductions in the first quarters of 2021 and 2020.
Loss on early extinguishment of debt increased $19 million due to make-whole call provisions paid upon redemption of $500 million in senior unsecured notes in the second quarter of 2021. See Note 16 to the consolidated financial statements for further detail.

Provision (benefit) for income taxes reflects an effective income tax rate of 38% in the second quarter of 2021, as compared to an effective income tax rate of 2% in the same period in 2020. See Note 6 to the consolidated financial statements for a more detailed discussion concerning the rate changes.
Segment Income
Segment income represents income that 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 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):
  Three Months Ended June 30,
(In millions) 2021 2020
United States $ 207  $ (365)
International 68  (6)
Segment income (loss) 275  (371)
Items not allocated to segments, net of income taxes (259) (379)
Net income (loss) $ 16  $ (750)
United States segment income (loss) in the second quarter of 2021 was $207 million of income versus a $365 million loss for the same period in 2020. The increase in income was primarily due to higher price realizations and lower DD&A expenses. These favorable changes were partially offset by higher realized losses on commodity derivatives and higher shipping and handling in the second quarter of 2021.
International segment income (loss) in the second quarter of 2021 was $68 million of income versus a $6 million loss for the same period in 2020, primarily due to higher price realizations that yielded positive effects on both consolidated operations and our equity method investees.

Net gain (loss) on commodity derivatives in the first six months of 2021 was a loss of $319 million, of which $162 million related to realized net losses and $157 million related to unrealized net losses, compared to a net gain of $132 million for the same period in 2020. We have multiple crude oil, natural gas and NGL 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 14 to the consolidated financial statements for further information.
Income (loss) from equity method investments increased $257 million for the first six months of 2021. We recognized an impairment of $152 million related to an investment in an equity method investee in the first six months of 2020. Additionally, we experienced higher price realizations in the first six months of 2021.
Production expenses for the first six months of 2021 decreased by $42 million compared to the same period in 2020, primarily as a result of the U.S. segment’s lower operational costs and continued cost management, specifically staffing and contract labor. International segment production expense amounts and rate decreased due to lower contract services and timing of project activity.
The following table provides production expense and production expense rates for each segment:

Shipping, handling and other operating expenses increased $70 million in the first six months of 2021 from the comparable 2020 period. As disclosed in our Form 10-K, certain of our processing arrangements with midstream entities are percentage-of-proceeds contracts. We classify the proceeds retained by the midstream companies as shipping and handling cost. The increase in shipping and handling costs of these percentage-of-proceeds contracts coincides with the increase in realized natural gas liquids prices.
Exploration expenses include unproved property impairments, dry well costs, geological and geophysical, and other costs.

Impairments decreased $50 million in the first six months of 2021. Impairments in 2021 consisted of a $24 million impairment as we decommissioned certain Eagle Ford central facilities and a $22 million impairment related to 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 2020, we impaired goodwill for $95 million related to our International reporting unit in the first quarter of 2020. See Note 10, Note 11, and Note 23 for discussion of the impairments in further detail.
Taxes other than income include production, severance and ad valorem taxes, primarily in the U.S., which tend to increase or decrease in relation to revenue and sales volumes. Taxes other than income increased $52 million primarily due to higher price realizations in the U.S. segment in the first six months of 2021.
Net interest and other decreased $61 million in the first six months of 2021 versus the same period in 2020, primarily as a result of $49 million mark-to-market gains on forward starting interest rate swaps in the first six months of 2021. See Note 14 for further detail discussion of the interest rate swaps in the consolidated financial statements.
Loss on early extinguishment of debt increased $19 million due to make-whole call provisions paid upon redemption of $500 million in senior unsecured notes in the second quarter of 2021. See Note 16 to the consolidated financial statements for further detail.
Provision (benefit) for income taxes reflects an effective income tax rate of 15% in the first six months of 2021, as compared to an effective income tax rate of 2% in the same period in 2020. See Note 6 to the consolidated financial statements for a more detailed discussion concerning the rate changes.

Segment Income
Segment income represents income that 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 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):
  Six Months Ended June 30,

Segment income (loss) 537  (392)
Items not allocated to segments, net of income taxes (424) (404)
Net income (loss) $ 113  $ (796)
United States segment income (loss) for the first six months of 2021 was $419 million of income versus a $385 million loss loss for the same period in 2020. This increase was primarily due to higher price realizations and lower DD&A expenses. These favorable changes were partially offset by lower sales volumes, realized losses on commodity derivatives (as compared to realized gains in the prior period), and higher shipping and handling costs in the first six months of 2021.
International segment income (loss) for the first six months of 2021 was $118 million of income versus a $7 million loss for the same period in 2020, primarily due to higher price realizations in E.G. in the second quarter of 2021.

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. As commodity prices increased during the first six months of 2021, we generated positive cash flow from operations. We continue to expect volatility in commodity prices and that could impact how much cash flow from operations we generate. The following table presents sources and uses of cash and cash equivalents:
Six Months Ended June 30,
(In millions) 2021 2020
Sources of cash and cash equivalents    
Operating activities $ 1,277  $ 710

Purchases of common stock (9) (92)
Dividends paid (55) (40)
Other (23) — 
Total uses of cash and cash equivalents $ (1,070) $ (1,066)
Cash flows generated from operating activities in the first six months of 2021 were 80% 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 production volumes, and increased working capital usage.
The following table shows capital expenditures by segment and reconciles to additions to property, plant and equipment as presented in the consolidated statements of cash flows:
Six Months Ended June 30,

Corporate
Total capital expenditures 473  707 
Change in capital expenditure accrual 10  239 
Total use of cash and cash equivalents for property, plant and equipment $ 483  $ 946 
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 resource plays.
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, 2021, we had approximately $4.1 billion of liquidity consisting of $970 million in cash and cash equivalents and $3.1 billion available under our revolving Credit Facility.
38


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.
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. 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.
Capital Resources
Credit Arrangements and Borrowings
In June 2021, we executed the sixth amendment to our unsecured 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 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 no 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 pay 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 this redemption. Subsequent to the redemption of the 2025 Notes, our next significant long-term debt maturity is in the amount of $1.0 billion due 2027. Refer to our 2020 Annual Report on Form 10-K for a listing of our long-term debt maturities.
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 lessor and other participants are providing financing for up to $340 million to fund the estimated project costs. As of June 30, 2021, project costs incurred totaled approximately $214 million, including land acquisition and construction costs.
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 24% and 26% at June 30, 2021 and December 31, 2020.
Capital Requirements
Share Repurchase Program
No share repurchases were made under our share repurchases program during the six months ended June 30, 2021; however, we repurchased $9 million of shares during the first quarter related to our tax withholding obligation associated with the vesting of employee restricted stock awards. Our share repurchase program has $1.3 billion of remaining authorization.

39



Contractual Cash Obligations
As of June 30, 2021, there are no material changes to our consolidated cash obligations to make future payments under existing contracts, as disclosed in our 2020 Annual Report on Form 10-K.
Environmental Matters and Other Contingencies
We have incurred and will continue to incur capital, operating and maintenance and remediation expenditures as a result of environmental laws and regulations. If these expenditures, as with all costs, are not ultimately offset by the prices we receive for our products and services, our operating results will be adversely affected. 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.
Other than the items set forth in Part II - Item 1. Legal Proceedings, there have been no significant changes to the environmental, health and safety matters under Item 1. Business or Item 3. Legal Proceedings in our 2020 Annual Report on Form 10-K. See Note 23 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 14 and Note 15 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, 2021, we had various open commodity derivatives. Based on the June 30, 2021 published NYMEX WTI, natural gas and natural gas liquids futures prices, a hypothetical 10% change (per bbl for crude oil, per MMbtu for gas and per bbl for NGL) would change the fair values of our commodity derivative positions to the following:
(In millions) Fair Value Hypothetical Price Increase of 10% Hypothetical Price Decrease of 10%
Derivative asset (liability) - Crude Oil $ (133) $ (157) $ (37)
Derivative asset (liability) - Natural Gas (26) (39) (14)
Derivative asset (liability) - NGL (22) (28) (17)
Total $ (181) $ (224) $ (68)

Interest Rate Risk
At June 30, 2021, our portfolio of current and long-term debt is comprised of fixed-rate instruments with an outstanding balance of $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, 2021, we had forward starting interest rate swap agreements with a total notional amount of $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 the 1-month LIBOR component of future lease payments on our future Houston office. A hypothetical 10% change in interest rates would change the fair values of our cash flow hedge and de-designated cash flow hedge positions to the following as of June 30, 2021:
(In millions) Fair Value Hypothetical Interest Rate Increase of 10% Hypothetical Interest Rate Decrease of 10%
Interest rate asset (liability) - designated as cash flow hedges $ (8) $ (7) $ (9)
Interest rate asset (liability) - not designated as cash flow hedges 62  79  50 
Total $ 54  $ 72  $ 41 
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, 2021.  
During the first six months of 2021, 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
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.
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.
Other than the items set forth above, there have been no significant changes to Item 3. Legal Proceedings in our 2020 Annual Report on Form 10-K. See Note 23 to the consolidated financial statements included in Part I, Item I for a description of such legal and administrative proceedings and Item 3. Legal Proceedings in our 2020 Annual Report on Form 10-K.
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 2020 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 2020 Annual Report on Form 10-K.

As of June 30, 2021, we have repurchased 191 million common shares at a cost of approximately $5.8 billion, excluding transaction fees and commissions. Purchases under the program are made at our discretion and may be in either open market transactions, including block purchases, or in privately negotiated transactions using cash on hand, cash generated from operations, or proceeds from potential asset sales. This program may be changed based upon our financial condition or changes in market conditions and is subject to termination prior to completion. In connection with the economic downturn, during the second quarter of 2020, the Company temporarily suspended the share repurchase program. Shares repurchased as of June 30, 2021 were held as treasury stock.
