NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION

Description of the Business

We are a leading, integrated, downstream energy company headquartered in Findlay, Ohio. We operate the nation's largest refining system. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market and to independent entrepreneurs who operate ~~approximately 7,000~~ branded outlets. We also sell transportation fuel to consumers through ~~approximately 1,070~~ direct dealer locations under long-term supply contracts. MPC’s midstream operations are primarily conducted through MPLX LP (“MPLX”), which owns and operates crude oil and light product transportation and logistics infrastructure as well as gathering, processing and fractionation assets. We own the general partner and a majority limited partner interest in MPLX.

On August 2, 2020, we entered into a definitive agreement to sell Speedway, our company-owned and operated retail transportation fuel and convenience store business, to 7-Eleven, Inc. (“7-Eleven”) for $21 billion in cash, subject to certain adjustments based on the levels of cash, debt ~~(as defined in the agreement)~~ and working capital at closing and certain other items. The taxable transaction is expected to close in the ~~first~~second quarter of 2021, subject to customary closing conditions and the receipt of regulatory approvals. ~~We will retain our direct dealer business.~~

As a result of the agreement to sell ~~the~~ Speedway, ~~business,~~ its results are reported separately as discontinued operations, net of tax, in our consolidated statements of income for all periods presented and its assets and liabilities ~~have been~~are presented in our consolidated balance sheets as assets and liabilities held for sale. In addition, we separately disclosed the operating and investing cash flows of ~~the~~ Speedway ~~business~~ as discontinued operations within our consolidated statements of cash flow. See Note 43 for discontinued operations disclosures.

Prior to presentation of Speedway as discontinued operations, Speedway and our retained direct dealer business were the two reporting units within our Retail segment. Beginning with the third quarter of 2020, the direct dealer business is managed as part of the Refining & Marketing segment. The results of the Refining & Marketing segment have been retrospectively adjusted to include the results of the direct dealer business in all periods presented. See Note 11 ~~for our segment reporting disclosures.~~

Basis of Presentation

All significant intercompany transactions and accounts have been eliminated.

~~As a result of our agreement to sell Speedway, the following changes in our basis of presentation have occurred:~~

In accordance with ASC 205, Discontinued Operations, intersegment sales from our Refining & Marketing segment to the Speedway business are no longer eliminated as intercompany transactions and are now presented within sales and other operating revenue, since we will continue to supply fuel to the Speedway business subsequent to the sale to 7-Eleven. All periods presented have been retrospectively adjusted to reflect this change.

~~Certain prior period financial statement amounts have been reclassified to conform to current period presentation.~~

These interim consolidated financial statements are unaudited; however, in the opinion of our 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 otherwise disclosed. These interim consolidated financial statements, including the notes, have been prepared in accordance with the rules of the SEC applicable to interim period financial statements and do not include all of the information and disclosures required by GAAP for complete financial statements.

These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, ~~2019.~~2020. The results of operations for the three ~~and nine~~ months ended ~~September 30, 2020~~March 31, 2021 are not necessarily indicative of the results to be expected for the full year.

In accordance with ASC 205, Discontinued Operations, intersegment sales from our Refining & Marketing segment to Speedway are no longer eliminated as intercompany transactions and are now presented within sales and other operating revenue, since we will continue to supply fuel to Speedway subsequent to the sale to 7-Eleven. All periods presented have been retrospectively adjusted to reflect this change. Additionally, beginning August 2, 2020, in accordance with ASC 360, Property, Plant, and Equipment, we ceased recording depreciation and amortization for Speedway’s property, plant and equipment, finite-lived intangible assets and right of use lease assets.

2. ACCOUNTING STANDARDS

Recently Adopted

Effective January 1, 2020, we adopted ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” using the modified retrospective transition method. The amendment requires entities

~~Table of Contents~~

to consider a broader range of information to estimate expected credit losses, which may result in earlier recognition of losses. The ASU requires the company to utilize an expected loss methodology in place of the incurred loss methodology for financial instruments, including trade receivables, and off-balance sheet credit exposures. Adoption of the standard did not have a material impact on our financial statements.

We are exposed to credit losses primarily through our sales of refined petroleum products, crude oil and midstream services. We assess each customer’s ability to pay through our credit review process. The credit review process considers various factors such as external credit ratings, a review of financial statements to determine liquidity, leverage, trends and business specific risks, market information, pay history and our business strategy. Customers that do not qualify for payment terms are required to prepay or provide a letter of credit. We monitor our ongoing credit exposure through timely review of customer payment activity. At September 30, 2020, we reported $4,911 million of accounts and notes receivable, net of allowances of $22 million.

~~We are also exposed to credit losses from off-balance sheet exposures, such as guarantees of joint venture debt. See Note 24 for more information on these off-balance sheet exposures.~~

We ~~also~~ adopted the following ~~ASUs~~ASU during the first ~~nine~~three months of ~~2020,~~2021, which ~~also~~ did not have a material impact to our financial statements or financial statement disclosures:


ASU			Effective Date
2019-12		Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes	January 1, 2021

~~ASU~~		~~Effective Date~~
~~2018-13~~	~~Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement~~	~~January 1, 2020~~
~~2020-04~~	~~Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting~~	~~April 1, 2020~~

~~Not Yet Adopted~~

~~ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes~~

In December 2019, the FASB issued new guidance to simplify the accounting for income taxes. Amendments include removal of certain exceptions to the general principles of ASC 740 and simplification in several other areas such as accounting for a franchise tax or similar tax that is partially based on income. The change is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. We do not expect the application of this ASU to have a material impact on our consolidated financial statements.

3. ~~RESTRUCTURING~~

During the third quarter of 2020, we announced strategic actions to lay a foundation for long-term success, including plans to optimize our assets and structurally lower costs in 2021 and beyond, which included indefinitely idling the refineries located in Gallup, New Mexico and Martinez, California and the approval of an involuntary workforce reduction plan. In connection with these strategic actions, we recorded restructuring expenses of $348 million for the three months ended September 30, 2020.

The indefinite idling of the Gallup and Martinez refineries and progression of activities associated with the conversion of the Martinez refinery to a renewable diesel facility resulted in $189 million of restructuring expenses. Of the $189 million of restructuring expenses, we expect $130 million to settle in cash for costs related to decommissioning refinery processing units and storage tanks and fulfilling environmental remediation obligations. Additionally, we recorded a non-cash reserve against our materials and supplies inventory at these facilities of $51 million.

The involuntary workforce reduction plan, together with employee reductions resulting from MPC's indefinite idling of its Martinez and Gallup refineries, affected approximately 2,050 employees. We recorded $159 million of restructuring expenses for separation benefits payable under our employee separation plan and certain collective bargaining agreements that we expect to settle in cash. Certain of the affected MPC employees provide services to MPLX. MPLX has various employee services agreements and secondment agreements with MPC pursuant to which MPLX reimburses MPC for employee costs, along with the provision of operational and management services in support of MPLX’s operations. Pursuant to such agreements, MPC was reimbursed by MPLX for $36 million of the $159 million of restructuring expenses recorded for these actions.

As of September 30, 2020, $291 million of restructuring expenses were accrued as restructuring reserves within payroll and benefits payable, other current liabilities and deferred credits and other liabilities within our consolidated balance sheets. We expect cash payments for the majority of these reserves to occur within the next twelve months.

4. DISCONTINUED OPERATIONS AND ASSETS HELD FOR SALE

On August 2, 2020, we entered into a definitive agreement to sell Speedway to 7-Eleven ~~Inc.~~ for $21 billion, subject to certain adjustments based on the levels of cash, debt ~~(as defined in the agreement)~~ and working capital at closing and certain other items. The taxable transaction is expected to close in the ~~first~~second quarter of 2021, subject to customary closing conditions and the receipt of regulatory approvals.

As a result of the agreement to sell ~~the~~ Speedway, ~~business,~~ its results are reported separately as discontinued operations, net of tax, in our consolidated statements of income for all periods presented and its assets and liabilities ~~have been~~are presented in our consolidated balance sheets as assets and liabilities held for sale. Additionally, beginning August 2, 2020, in accordance with ASC 360,

Table of Contents

Property, Plant, and Equipment, we ceased recording depreciation and amortization for ~~the Speedway business’~~Speedway’s property, plant and equipment, finite-lived intangible assets and right of use lease assets. In addition, we separately disclosed the operating and investing cash flows of ~~the~~ Speedway ~~business~~ as discontinued operations within our consolidated statements of cash flow.

The following tables present Speedway results as reported in income from discontinued operations, net of tax, within our consolidated statements of income and the carrying value of assets and liabilities as presented within assets and liabilities held for sale on our consolidated balance sheets.

Separation Agreements

In connection with the definitive agreement to sell the Speedway business, we have agreed to enter into avarious 15-year fuel supply ~~agreement,~~agreements, at closing, through which we will continue to supply fuel to ~~the~~ Speedway ~~business~~ subsequent to the sale to 7-Eleven. Due to our expected continuing involvement with ~~the~~ Speedway ~~business~~ through a fuel supply ~~agreement,~~agreements, intersegment sales from our Refining & Marketing segment to ~~the~~ Speedway ~~business~~ are no longer eliminated as intercompany transactions and are now presented within sales and other operating revenue.

Purchase of Speedway’s Interest in PFJ Southeast

5. During the fourth quarter of 2020, Pilot Travel Centers LLC exercised an option to purchase our 29 percent interest in PFJ Southeast LLC (“PFJ”), subject to customary closing conditions and the receipt of regulatory approvals. PFJ has been accounted for as an asset held for sale as of September 30, 2020 and is reported as the equity method investment balance in the above table.

4. MASTER LIMITED PARTNERSHIP

We own the general partner and a majority limited partner interest in MPLX, which owns and operates crude oil and light product transportation and logistics infrastructure as well as gathering, processing and fractionation assets. We control MPLX through our ownership of the general partner interest and, as of ~~September 30, 2020~~March 31, 2021, we owned approximately 6263 percent of the outstanding MPLX common units.

Unit Repurchase Program

On November 2, 2020, MPLX announced its board authorized a unit repurchase program for the ~~redemption~~repurchase of ~~MPLX~~up to $1 billion of MPLX’s outstanding common units held by ~~WRSW. The transaction effects~~ the ~~transfer to MPC of~~public.

During the Western wholesale distribution business that MPLX acquired as a result of its acquisition of Andeavor Logistics LP (“ANDX”). Beginning in the third quarter of 2020, the results of these operations are presented in MPC’s Refining & Marketing segment.

~~At the closing, per the terms of Redemption Agreement, MPLX redeemed 18,582,088~~three months ended March 31, 2021, 6,272,981 MPLX common units ~~(the “Redeemed Units”) held by WRSW. The number~~had been repurchased at an average cost per unit of ~~Redeemed Units~~$24.78. Total cash paid for units repurchased during the three months ended March 31, 2021 was ~~calculated by dividing WRW’s aggregate valuation~~$155 million. As of ~~$340 million by the simple average of the volume weighted average New York Stock Exchange prices of an~~March 31, 2021, MPLX ~~common unit for the ten trading days ending at market close on July 27, 2020.

~~MPLX’s Acquisition of ANDX~~

On July 30, 2019, MPLX completed its acquisition of ANDX, and ANDX survived as a wholly owned subsidiary of MPLX. At the effective time of the ANDX acquisition, each common unit held by ANDX’s public unitholders was converted into the righthad agreements to ~~receive 1.135 MPLX common units. ANDX~~acquire 291,400 additional common units ~~held by MPC were converted into the right to receive 1.0328 MPLX common units. Additionally, as a result~~for $7 million, which settled in early April 2021. As of MPLX’s acquisition of ANDX, 600,000 ANDX preferred units were converted into 600,000 preferred units of MPLX (“Series B preferred units”). Series B preferred unitholders are entitled to receive, when and if declared by the board of directors of MPLX’s general partner, a fixed distribution of $68.75 per unit, per annum, payable semi-annually in arrears on February 15 and August 15, or the first business day thereafter, up to and including February 15, 2023. After February 15, 2023, the holders of Series B preferred units are entitled to receive cumulative, quarterly distributions payable in arrearsMarch 31, 2021, $812 million remained outstanding on the ~~15th day~~program for future purchases.

MPLX may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block transactions, tender offers, accelerated unit repurchases or open market solicitations for units, some of ~~February, May, August~~which may be effected through Rule 10b5-1 plans. The timing and ~~November~~amount of ~~each year,~~repurchases will depend upon several factors, including market and business conditions, and repurchases may be initiated, suspended or ~~the first business day thereafter, based on a floating annual rate equal to the three month LIBOR plus 4.652 percent.~~

MPC accounted for this transaction as a common control transaction, as defined by ASC 805, which resulted in an increase to noncontrolling interest and a decrease to additional paid-in capital of approximately $55 million, net of tax. During the third quarter of 2019, we pushed down to MPLX the portion of the goodwill attributable to ANDX as of October 1, 2018, the date of our acquisition of Andeavor. Due to this push down of goodwill, we also recorded an incremental $642 million deferred tax liability associated with the portion of the non-deductible goodwill attributable to the noncontrolling interest in MPLX with an offsetting reduction of our additional paid-in capital balance. We have consolidated ANDX since we acquired Andeavor on October 1, 2018 in accordance with ASC 810.discontinued at any time. The repurchase authorization has no expiration date.

Agreements

We have various long-term, fee-based commercial agreements with MPLX. Under these agreements, MPLX provides transportation, storage, distribution and marketing services to us. With certain exceptions, these agreements generally contain minimum volume commitments. These transactions are eliminated in consolidation but are reflected as intersegment transactions between our Refining & Marketing and Midstream segments. We also have agreements with MPLX that establish fees for operational and management services provided between us and MPLX and for executive management services and certain general and administrative services provided by us to MPLX. These transactions are eliminated in consolidation but are reflected as intersegment transactions between our Corporate and Midstream segments.

Noncontrolling Interest

As a result of equity transactions of MPLX, ~~and ANDX,~~ we are required to adjust non-controlling interest and additional paid-in capital. Changes in MPC’s additional paid-in capital resulting from changes in its ownership interests in MPLX ~~and ANDX~~ were as follows:

6. 5. IMPAIRMENTS

The outbreak of COVID-19 and its development into a pandemic in March 2020 have resulted in significant economic disruption globally. Actions taken by various governmental authorities, individuals and companies around the world to prevent the spread of COVID-19 through social distancing have restricted travel, many business operations, public gatherings and the overall level of individual movement and in-person interaction across the globe. This has in turn significantly reduced global economic activity and resulted in a decrease in motor vehicle use at a time when seasonal driving patterns typically result in an increase of consumer demand for gasoline and a dramatic reduction in airline flights. These macroeconomic conditions and certain global geopolitical events in the first quarter of 2020 contributed to a significant decline in crude oil prices as well as an increase in crude oil price volatility. The decrease in demand for refined petroleum products has resulted in a significant decrease in the price and volume of the refined petroleum products we produce and sell as compared to the three and nine months ended September 30, 2019.

During the first quarter of 2020, the outbreak of COVID-19 caused overall deterioration in the economy and the environment in which we ~~operate, the~~operate. The related changes to our expected future cash flows, as well as a sustained decrease in share price, were considered triggering events requiring the performance of various ~~impairment assessments~~tests of the carrying values of our assets. Triggering events requiring the performance of various tests of the carrying value of our Midstream assets ~~which resulted~~were also identified by MPLX as a result of the overall deterioration in the ~~majority of~~economy and the ~~impairment charges for~~environment in which MPLX and its customers operate, which led to a reduction in forecasted volumes processed by the ~~nine months ended September 30, 2020,~~systems operated by MarkWest Utica EMG, L.L.C., MPLX’s equity method investee, as ~~discussed below.~~

well as a sustained decrease in the MPLX unit price.

Goodwill

During the first quarter of 2020, we recorded an impairment of goodwill of $7.33 billion. ~~See the table below for detail by segment.~~ The $5.516 billion goodwill impairment within the Refining & Marketing segment was primarily driven by the effects of COVID-19 and the decline in commodity prices. The $1.814 billion impairment within the Midstream segment was primarily driven by additional information related to the slowing of drilling activity, which ~~has~~had reduced production growth forecasts from MPLX’s producer customers.

During the third quarter of 2020, we recorded an impairment of goodwill of $64 million. The $64 million of goodwill was transferred from our Midstream segment to our Refining & Marketing segment during the third quarter of 2020 in connection with the transfer to MPC of the MPLX wholesale distribution business as described in Note 5. The transfer required goodwill impairment tests for the transferor and transferee reporting units. Our Refining & Marketing reporting unit that recorded the $64 million impairment expense has no remaining goodwill.

The fair values of the reporting units for the first quarter of 2020 goodwill impairment analysis were determined based on applying both a discounted cash flow method, or income approach, as well as a market approach. The discounted cash flow fair value estimate is based on known or knowable information at the measurement date. The significant assumptions that were used to develop the estimates of the fair values under the discounted cash flow method included management’s best estimates of the expected future results and discount rates, which range from 9.0 percent to 13.5 percent. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the interim goodwill impairment test will prove to be an accurate prediction of the future. The fair value measurements for the individual reporting units’ overall fair values represent Level 3 measurements.

Equity Method Investments

During the first quarter of 2020, we recorded equity method investment impairment charges totaling $1.315 billion, of which $1.25 billion related to MarkWest Utica EMG, L.L.C. and its investment in Ohio Gathering Company, L.L.C. The impairments were largely due to a reduction in forecasted volumes gathered and processed by the systems operated by the ~~joint ventures.~~equity method investments. The fair value of the investments was determined based upon applying the discounted cash flow method, ~~which is~~ an income approach. The discounted cash flow fair value estimate is based on known or knowable information at the interim measurement date. The significant assumptions that were used to develop the estimate of the fair value under the discounted cash flow method include management’s best estimates of the expected future cash flows, including prices and volumes, the weighted average cost of capital and the long-term growth rate. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the impairment test will prove to be an accurate prediction of the future. The fair value of these equity method investments ~~represents~~represent a Level 3 measurement.

Long-lived Assets

Long-lived assets used in operations are assessed for impairment whenever changes in facts and circumstances indicate that the carrying value of the assets may not be recoverable based on the expected undiscounted future cash flow of an asset group. For purposes of impairment evaluation, long-lived assets must be grouped at the lowest level for which independent cash flows can be identified, which generally is the refinery and associated distribution system level for Refining & Marketing segment assets and the plant level or pipeline system level for Midstream segment assets. If the sum of the undiscounted estimated pretax cash flows is less than the carrying value of an asset group, fair value is calculated, and the carrying value is written down to the calculated fair value.

During the first quarter of 2020, we identified long-lived asset impairment triggers relating to all 16 of our refinery asset groups within the Refining & Marketing segment as a result of decreases to the Refining & Marketing segment expected future cash flows. The cash flows associated with these assets were significantly impacted by the effects of COVID-19 and commodity price declines. We ~~assessed~~performed recoverability tests for each refinery asset group ~~for impairment~~ by comparing the undiscounted estimated pretax cash flows to the carrying value of each asset group. ~~Of the 16 refinery asset groups, only~~Only the Gallup refinery’s carrying value exceeded its undiscounted estimated pretax cash flows. It was determined that the fair value of the Gallup refinery’s property, plant and equipment was less than the carrying value. As a result, we recorded a charge of $142 million in the first quarter of 2020 to impairment expense on the consolidated statements of income. ~~The fair value measurements for the Gallup refinery assets represent Level 3 measurements.~~

During the second quarter of 2020, we identified long-lived asset impairment triggers relating to all of our refinery asset groups within the Refining & Marketing segment, except the Gallup refinery which had been impaired in the first quarter, as a result of continued macroeconomic developments impacting the Refining & Marketing segment expected future cash flows. All of these refinery asset groups’ undiscounted estimated pretax cash flows exceeded their carrying value by at least 17 percent. The determination of undiscounted estimated pretax cash flows utilized significant assumptions including management’s best estimates of the expected future cash flows, allocation of certain Refining & Marketing segment cash flows to the individual refineries, the estimated useful lives of the asset groups, and the salvage values of the refineries.

On August 3, 2020, we announced our plans to evaluate possibilities to strategically reposition our Martinez refinery, including the potential conversion of the refinery into a renewable diesel facility. Subsequent to August 3, 2020, we progressed activities associated with the conversion of the Martinez refinery to a renewable diesel facility, including applying for permits, advancing discussions with feedstock suppliers, and beginning detailed engineering activities. As envisioned, the Martinez facility would be expected to start producing renewable diesel in 2022, with a potential to build to full capacity of 48,000 barrels per day in 2023. As a result of the progression of these activities, we identified assets that would be repurposed and utilized in a renewable diesel facility configuration and assets that would be abandoned since they had no function in a renewable diesel facility configuration. This change in our intended use for the Martinez refinery is a long-lived asset impairment trigger for the assets that would be repurposed and remain as part of the Martinez asset group. We assessed the asset group for impairment by comparing the undiscounted estimated pretax cash flows to the carrying value of the asset group and the undiscounted estimated pretax cash flows exceeded the Martinez asset group carrying value. We recorded impairment expense of $342 million for the abandoned assets as we are no longer using these assets and have no expectation to use these assets in the future. Additionally, as a result of our efforts to progress the conversion of Martinez refinery into a renewable diesel facility, MPLX cancelled in-process capital projects related to its Martinez refinery logistics operations resulting in impairments of $27 million in the third quarter.

The determinations of expected future cash flows and the salvage values of refineries, as described earlier, require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of our impairment analysis will prove to be an accurate prediction of the future.

~~Table of Contents~~

Should our assumptions significantly change in future periods, it is possible we may determine the carrying values of certain of our refinery asset groups exceed the undiscounted estimated pretax cash flows of their refinery asset groups, which would result in future impairment charges.

During the first quarter of 2020, we identified an impairment trigger relating to asset groups within MPLX’s Western Gathering and Processing (“G&P&P”) reporting unit as a result of significant changes to expected future cash flows for these asset groups resulting from the effects of COVID-19. The cash flows associated with these assets were significantly impacted by volume declines reflecting decreased forecasted producer customer production as a result of lower commodity prices. We assessed each asset group within the Western G&P reporting unit for impairment. It was determined that the fair value of the East Texas G&P asset group’s underlying assets were less than the carrying value. As a result, MPLX recorded impairment charges totaling $350 million related to its property, plant and equipment and intangibles, which are included in impairment expense on our consolidated statements of income.

Fair ~~value~~values of property, plant and equipment ~~was~~were determined using a combination of an income and cost ~~approach.~~approaches. The income approach utilized significant assumptions including management’s best estimates of the expected future cash flows and the estimated useful life of the asset ~~group.~~groups. The cost approach utilized assumptions for the current replacement costs of similar assets adjusted for estimated depreciation and deterioration of the existing equipment and economic obsolescence. The fair value of the intangibles was determined based on applying the multi-period excess earnings method, which is an income approach. Key assumptions included management’s best estimates of the expected future cash flows from existing customers, customer attrition rates and the discount rate. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the impairment analysis will prove to be an accurate prediction of the future. The fair value measurements for the Gallup refinery and East Texas G&P asset ~~group fair values~~groups represent Level 3 measurements.

7. 6. VARIABLE INTEREST ENTITIES

Consolidated VIE

We control MPLX through our ownership of its general partner. MPLX is a VIE because the limited partners do not have substantive kick-out or participating rights over the general partner. We are the primary beneficiary of MPLX because in addition to our significant economic interest, we also have the ability, through our ownership of the general partner, to control the decisions that most significantly impact MPLX. We therefore consolidate MPLX and record a noncontrolling interest for the interest owned by the public. We also record a redeemable noncontrolling interest related to MPLX’s Series A preferred units.

The creditors of MPLX do not have recourse to MPC’s general credit through guarantees or other financial arrangements, except as noted. MPC has effectively guaranteed certain indebtedness of LOOP LLC (“LOOP”) and LOCAP LLC (“LOCAP”), in which MPLX holds an interest. See Note 2422 for more information. The assets of MPLX can only be used to settle their own obligations and their creditors have no recourse to our assets, except as noted earlier.

9. ~~EARNINGS~~8. LOSS PER SHARE

We compute basic earnings (loss) per share by dividing net income (loss) attributable to MPC less income allocated to participating securities by the weighted average number of shares of common stock outstanding. Since MPC grants certain incentive compensation awards to employees and non-employee directors that are considered to be participating securities, we have calculated our earnings (loss) per share using the two-class method. Diluted income (loss) per share assumes exercise of certain stock-based compensation awards, provided the effect is not anti-dilutive.

~~11.~~ 9. SEGMENT INFORMATION

On August 2, 2020 we entered into a definitive agreement to sell Speedway to 7-Eleven, Inc. for $21 billion in cash, subject to certain adjustments based on the levels of cash, debt (as defined in the agreement) and working capital at closing and certain other items. In connection with the announced sale, we reassessed our organizational structure and management of segments. As a result of this assessment, we have made the following changes for all periods presented:

~~Speedway’s results are presented separately as discontinued operations. See Note 4 for related disclosures.~~

Refining & Marketing intersegment sales to Speedway that were previously eliminated in consolidation are reported as third party sales as we will continue to supply fuel to the Speedway business following its disposition.

~~The retained direct dealer business results, previously included in the Retail segment, are reported within the Refining & Marketing segment.~~

~~As a result of the above, we no longer present a separate Retail segment, which had included these two businesses.~~

~~Corporate costs are no longer allocated to Speedway under discontinued operations accounting.~~

We have 2 reportable segments: Refining & Marketing and Midstream. Each of these segments is organized and managed based upon the nature of the products and services it offers.

•

•Refining & Marketing – refines crude oil and other feedstocks at our refineries in the Gulf Coast, Mid-Continent and West Coast regions of the United States, purchases refined products and ethanol for resale and distributes refined products through transportation, storage, distribution and marketing services provided largely by our Midstream segment. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to independent entrepreneurs who operate primarily Marathon® branded outlets, through long-term fuel supply contracts with direct dealers who operate locations mainly under the ARCO® brand and to approximately 3,800 Speedway locations.

•^® ~~branded outlets, through long-term fuel supply contracts with direct dealers who operate locations mainly under the ARCO~~^® ~~brand and to approximately 3,900 Speedway locations.~~

Midstream – transports, stores, distributes and markets crude oil and refined products principally for the Refining & Marketing segment via refining logistics assets, pipelines, terminals, towboats and barges; gathers, processes and transports natural gas; and gathers, transports, fractionates, stores and markets NGLs. The Midstream segment primarily reflects the results of MPLX.

Table of Contents

Segment income represents income (loss) from operations attributable to the reportable segments. Corporate administrative expenses, except for those attributable to MPLX, and costs related to certain non-operating assets are not allocated to the Refining & Marketing segment. In addition, certain items that affect comparability (as determined by the chief operating decision ~~maker)~~maker (“CODM”)) are not allocated to the reportable segments. Assets by segment are not a measure used to assess the performance of the company by the CODM and thus are not reported in our disclosures.

11. INCOME TAXES

We have historically provided for income taxes during interim reporting periods based on an estimate of the annual effective tax rate applied to book income for the year to date interim period. For 2020, we continue to utilize this approach.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted by Congress and signed into law by the President in response to the COVID-19 pandemic. The CARES Act contains numerous income tax provisions, some of which have the potential to materially impact MPC's calculation of income taxes including:

~~Revising the limitations on the deductibility of interest from 30 percent of adjusted taxable income to 50 percent.~~

Ability to carry back tax net operating losses ("NOL") five years for NOLs arising in taxable years 2018 through 2020. This provision allows the taxpayer to recover taxes previously paid at a 35 percent federal income tax rate during years prior to 2018. The limitation on the percentage of taxable income that may be offset by the NOL, formerly 80 percent of income, was eliminated for years beginning before 2021.

The income tax benefit from continuing and discontinued operations, as recorded on the balance sheet, was $2.0 billion for the nine months ended September 30, 2020. Approximately $354 million of the recorded benefit was attributable to the income tax rate differential in the NOL carryback years. Absent the CARES Act, we would have recorded a ~~deferred tax asset for the expected NOL carryforward under the currently effective federal income tax rate.~~

Based on the estimated NOL carryback, as provided by the CARES Act, we recorded an income tax receivable of $1.2 billion in other current assets to reflect our estimate of the tax refund we expect to realize from our 2020 federal tax return. The refund is expected to be received during the second half of 2021.

~~The~~ combined federal, state and foreign income tax ~~rate was 31 percent (tax benefit rate) and 19 percent~~provision of $34 million for the three months ended ~~September 30, 2020~~March 31, 2021, primarily due to certain permanent tax differences related to income attributable to noncontrolling interests, state taxes and ~~2019, respectively,~~unrecognized tax benefits. We recorded a combined federal, state and ~~16 percent and 20 percent~~foreign income tax benefit of $1,951 million for the ~~nine~~three months ended ~~September 30, 2020 and 2019, respectively. The~~March 31, 2020. Our effective tax benefit rate for the three months ended ~~September 30,~~March 31, 2020 was ~~higher~~lower than the U.S. statutory rate due to certain permanent tax benefits related to net income attributable to noncontrolling interests, state taxes, and a change in estimate related to the expected NOL carryback provided by the CARES Act offset by non-tax deductible goodwill impairment. The effective tax rate for the three months ended September 30, 2019 was less than the U.S. statutory rate primarily due to certain permanent tax differences related to net income attributable to noncontrolling interests offset by equity compensation and state and local tax expense. The effective tax rate for the nine months ended September 30, 2020 was lower than the statutory rate due to a significant amount of our pre-tax loss consisting of non-tax deductible goodwill impairment ~~charges, partially offset by the tax rate differential resulting from the expected NOL carryback provided under the CARES Act. The~~charges. Additionally, our effective tax rate is generally benefited by our noncontrolling interest in MPLX, but this benefit was lower for the ~~nine~~three months ended ~~September 30, 2019 was less than the U.S. statutory rate primarily~~March 31, 2020 due to ~~$36 million of state deferred tax expense~~impairment charges recorded ~~as an out of period adjustment, offset~~ by ~~permanent tax differences related to net income attributable to noncontrolling interests.~~

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was ~~not material~~enacted by Congress and signed into law by President Trump in response to ~~any previous period.~~

~~We are continuously undergoing examination~~the COVID-19 pandemic. The CARES Act contained a net operating loss (“NOL”) carryback provision, which allowed MPC to carryback our 2020 taxable loss to 2015 and later years. The five-year NOL carryback is available for all businesses producing taxable losses in 2018 through 2020 when tax was previously paid in the carryback years. As provided by the NOL carryback statute in the CARES Act, as of March 31, 2021, we have recorded an income tax receivable of $2.1 billion in other current assets. This reflects our estimate of the refund of previously paid tax we expect to receive during the second half of 2021 in connection with the filing of our ~~income~~2020 federal tax ~~returns, which have been completed through~~return.

14. RESTRUCTURING

During the third quarter of 2020, ~~market values for~~we indefinitely idled our refinery located in Gallup, New Mexico and initiated actions to strategically reposition our Martinez, California refinery to a renewable diesel facility. We also approved an involuntary workforce reduction plan. In connection with these ~~inventories were lower than their LIFO cost basis, resulting~~strategic actions, we recorded restructuring expenses of $367 million in 2020.

The indefinite idling of the Gallup refinery and actions to strategically reposition the Martinez refinery to a ~~reserve. The change from the LCM inventory valuation reserve at June 30, 2020~~renewable diesel facility resulted in ~~a benefit~~$195 million of ~~$530~~restructuring expenses. Of the $195 million of restructuring expenses, we expect $130 million to settle in cash for ~~the three months ended September 30, 2020.~~

~~The cost of inventories of crude oil~~costs related to decommissioning refinery processing units and ~~refined products is determined primarily under the LIFO method. During the three~~storage tanks and ~~nine month periods ended September 30, 2020,~~fulfilling environmental remediation obligations. Additionally, we recorded a ~~$256~~non-cash reserve against our materials and supplies inventory at these facilities of $51 million.

The involuntary workforce reduction plan, together with employee reductions resulting from our actions affecting the Gallup and Martinez refineries, affected approximately 2,050 employees. We recorded $172 million ~~charge~~of restructuring expenses for separation benefits payable under our employee separation plan and certain collective bargaining agreements that we expect to ~~reflect an expected LIFO liquidation for our crude oil inventories. The costs~~settle in cash. Certain of ~~inventories in~~ the ~~historical LIFO layer which is expected~~affected MPC employees provided services to ~~be liquidated are higher than current costs, which resulted in the charge to cost of revenues.~~

~~15.~~ ~~EQUITY METHOD INVESTMENTS~~

~~During the three months ended March 31, 2019, we executed~~MPLX. MPLX has various employee services agreements and secondment agreements with ~~Capline LLC~~MPC pursuant to ~~contribute~~which MPLX reimburses MPC for employee costs, along with the provision of operational and management services in support of MPLX’s operations. Pursuant to such agreements, MPC was reimbursed by MPLX for $37 million of the $172 million of restructuring expenses recorded for these actions.

Restructuring expenses were accrued as restructuring reserves within accounts payable, payroll and benefits payable, other current liabilities and deferred credits and other liabilities within our ~~33 percent undivided interest in~~consolidated balance sheets. We expect cash payments for the ~~Capline pipeline system in exchange for a 33 percent ownership interest in Capline LLC. In connection with our execution~~remaining exit and disposal costs reserve to occur through 2024.

Service from Cushing, Oklahoma is part of a joint tariff with Diamond pipeline.

2020.

Table of Contents

In accordance with ASC 810, we derecognized our undivided interest amounting to $143 million of net assets and recognized the Capline LLC ownership interest we received at fair value. We used an income approach to determine the fair value of our ownership interest under a Monte Carlo simulation method. We estimated the fair value of our ownership interest to be $350 million. This is a nonrecurring fair value measurement and is categorized in Level 3 of the fair value hierarchy. The Monte Carlo simulation inputs include ranges of tariff rates, operating volumes, operating cost and capital expenditure assumptions. The estimated cash flows were discounted using a Monte Carlo market participant weighted average cost of capital estimate. None of the inputs to the Monte Carlo simulation are individually significant. The excess of the estimated fair value of our ownership interest over the carrying value of the derecognized net assets resulted in a $207 million non-cash net gain recorded as a net gain on disposal of assets in the accompanying consolidated statements of income.

As the Capline system is currently idled, Capline LLC is unable to fund its operations without financial support from its equity owners and is a VIE. MPC is not deemed to be the primary beneficiary, due to our inability to unilaterally control significant decision-making rights. Our maximum exposure to loss as a result of our involvement with Capline LLC includes our equity investment, any additional capital contribution commitments and any operating expenses incurred by Capline LLC in excess of compensation received for performance of the operating services.

Represents the impact of netting assets, liabilities and cash collateral when a legal right of offset exists. As of September 30, 2020, cash collateral of less than $1 million was netted with the mark-to-market derivative liabilities. As of December 31, 2019, cash collateral of $51 million was netted with mark-to-market derivative liabilities.


^(b)	~~We have no derivative contracts that are subject to master netting arrangements reflected gross on the balance sheet.~~

Commodity derivatives in Level 1 are exchange-traded contracts for crude oil and refined products measured at fair value with a market approach using the close-of-day settlement prices for the market. Commodity derivatives are covered under master netting agreements with an unconditional right to offset. Collateral deposits in futures commission merchant accounts covered by master netting agreements related to Level 1 commodity derivatives are classified as Level 1 in the fair value hierarchy.

Level 2 instruments are valued based on quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices, such as liquidity, that are observable for the asset or liability. Commodity derivatives in Level 2 are OTC contracts, which are valued using market quotations from independent price reporting agencies, third-party brokers and commodity exchange price curves that are corroborated with market data.

Level 3 instruments ~~are OTC NGL contracts and~~include embedded derivatives in commodity contracts. The embedded derivative liability relates to a natural gas purchase agreement embedded in a keep‑whole processing agreement. The fair value calculation for these Level 3 instruments at ~~September 30, 2020~~March 31, 2021 used significant unobservable inputs including: (1) NGL prices interpolated and extrapolated due to inactive markets ranging from ~~$0.46~~$0.48 to ~~$0.97~~$1.36 per gallon with a weighted average of ~~$0.58~~$0.62 per gallon and (2) the probability of renewal of 100 percent for the first ~~five-year term~~ and ~~100 percent for the~~ second ~~five-year~~five-year term of the natural gas purchase agreement and the related keep-whole processing agreement. Increases or decreases in the fractionation spread result in an increase or decrease in the fair value of the embedded derivative liability. ~~An increase in the probability~~

Fair Values – Reported

We believe the carrying value of our other financial instruments, including cash and cash equivalents, receivables, accounts payable and certain accrued liabilities, approximate fair value. Our fair value assessment incorporates a variety of considerations, including the short-term duration of the instruments and the expected insignificance of bad debt expense, which includes an evaluation of counterparty credit risk. The borrowings under our revolving credit facilities, ~~and term loan facility,~~ which include variable interest rates, approximate fair value. The fair value of our fixed and floating rate long-term debt is based on prices from recent trade activity and is categorized in level 3 of the fair value hierarchy. The carrying and fair values of our debt were approximately ~~$31.4~~$32.0 billion and ~~$33.3~~$34.7 billion at ~~September 30, 2020,~~March 31, 2021, respectively, and approximately ~~$28.3~~$31.1 billion and ~~$30.1~~$34.9 billion at December 31, ~~2019,~~2020, respectively. These carrying and fair values of our debt exclude the unamortized issuance costs which are netted against our total debt.

~~18.~~ 16. DERIVATIVES

For further information regarding the fair value measurement of derivative instruments, including any effect of master netting agreements or collateral, see Note ~~17.~~15. We do not designate any of our commodity derivative instruments as hedges for accounting purposes.

Derivatives that are not designated as accounting hedges may include commodity derivatives used to hedge price risk on (1) inventories, (2) fixed price sales of refined products, (3) the acquisition of foreign-sourced crude oil, (4) the acquisition of ethanol for blending with refined products, (5) the sale of NGLs, ~~and~~ (6) the purchase of natural ~~gas.~~gas and (7) the purchase of soybean oil.

The following table presents the fair value of derivative instruments as of ~~September 30, 2020~~March 31, 2021 and December 31, ~~2019~~2020 and the line items in the balance sheets in which the fair values are reflected. The fair value amounts below are presented on a gross basis and do not reflect the netting of asset and liability positions permitted under the terms of our master netting arrangements including cash collateral on deposit with, or received from, brokers. We offset the recognized fair value amounts for multiple derivative instruments executed with the same counterparty in our financial statements when a legal right of offset exists. As a result, the asset and liability amounts below will not agree with the amounts presented in our consolidated balance sheets.

~~24.~~ 22. COMMITMENTS AND CONTINGENCIES

We are the subject of, or a party to, a number of pending or threatened legal actions, contingencies and commitments involving a variety of matters, including laws and regulations relating to the environment. Some of these matters are discussed below. For matters for which we have not recorded a liability, we are unable to estimate a range of possible loss because the issues involved have not been fully developed through pleadings, discovery or court proceedings. However, the ultimate resolution of some of these contingencies could, individually or in the aggregate, be material.

Environmental Matters

We are subject to federal, state, local and foreign laws and regulations relating to the environment. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites and certain other locations including presently or formerly owned or operated retail marketing sites. Penalties may be imposed for noncompliance.

Table of Contents

At ~~September 30, 2020~~March 31, 2021 and December 31, ~~2019,~~2020, accrued liabilities for remediation totaled ~~$388~~$393 million and ~~$396~~$397 million, respectively. It is not presently possible to estimate the ultimate amount of all remediation costs that might be incurred or the penalties, if any, that may be imposed. Receivables for recoverable costs from certain states, under programs to assist companies in clean-up efforts related to underground storage tanks at presently or formerly owned or operated retail marketing sites, were $6 million and $7 million ~~and $9 million~~ at ~~September 30, 2020~~March 31, 2021 and December 31, ~~2019,~~2020, respectively.

Governmental and other entities in ~~California, Delaware, Hawaii, Maryland, New York, South Carolina and Rhode Island~~various states have filed lawsuits against ~~coal, gas, oil and petroleum~~energy companies, including MPC. The lawsuits allege damages as a result of climate change and the plaintiffs are seeking unspecified damages and abatement under various tort theories. We are currently subject to such proceedings in federal or state courts in California, Delaware, Maryland, Hawaii, Rhode Island and South Carolina. Similar lawsuits may be filed in other jurisdictions. At this early stage, the ultimate outcome of these matters ~~remains~~remain uncertain, and neither the likelihood of an unfavorable outcome nor the ultimate liability, if any, can be determined.

We are involved in a number of environmental enforcement matters arising in the ordinary course of business. While the outcome and impact toon us cannot be predicted with certainty, management believes the resolution of these environmental matters will not, individually or collectively, have a material adverse effect on our consolidated results of operations, financial position or cash flows.

Other Legal Proceedings

In early July 2020, Tesoro High Plains Pipeline Company, LLC (“THPP”), a subsidiary of MPLX, received a Notification of Trespass Determination from the Bureau of Indian Affairs (“BIA”) relating to a portion of the Tesoro High Plains Pipeline that crosses the Fort Berthold Reservation in North Dakota. The notification covered the rights of way for 23 tracts of land and demanded the immediate cessation of pipeline operations. The notification also assessed trespass damages of approximately $187 million. ~~MPLX~~THPP appealed this determination, which triggered an automatic stay of the requested pipeline shutdown and payment. On October 29, the Assistant Secretary - Indian Affairs issued an order vacating the BIA’s trespass order and requiring the Regional Director for the BIA Great Plains Region to issue a new decision on or before December 15 covering all 34 tracts at issue. On December 15, the Regional Director of the BIA issued a new trespass notice to THPP consistent with the Assistant Secretary - Indian Affairs order vacating the prior trespass order. The new order found that THPP was in trespass and assessed trespass damages of approximately $4 million (including interest), which has been paid. The order also required THPP to immediately cease and desist use of the portion of the pipeline that crosses the property at issue. THPP has complied with the Regional Director’s December 15, 2020 notice. On February 12, 2021, landowners filed suit in the U.S. District Court for the District of North Dakota (the “District of North Dakota”) against THPP, the Department of the Interior, the Assistant Secretary - Indian Affairs, the Interior Board of Indian Appeals and the BIA, requesting, among other things, that decisions by the Assistant Secretary - Indian Affairs and the Interior Board of Indian Appeals be vacated as to the award of damages to plaintiffs. In March 2021, THPP received a copy of an order purporting to vacate all orders related to THPP’s alleged trespass issued by the BIA between July 2, 2020 and January 14, 2021. The order directs the Regional Director of the BIA to reconsider the issue of THPP’s alleged trespass and issue a new order, if necessary, after all interested parties have had an opportunity to be heard. Subsequently, landowners voluntarily dismissed the suit filed in the District of North Dakota. On April 23, 2021, THPP filed a lawsuit in the District of North Dakota against the United States of America, the U.S. Department of the Interior and the BIA challenging the March order purporting to vacate all previous orders related to THPP’s alleged trespass.

MPLX continues to work towards a settlement of this matter with holders of the property rights at issue. Management does not believe the ultimate resolution of this matter will have a material adverse effect on our consolidated financial position, results of operations, or cash flows.

We are also a party to a number of other lawsuits and other proceedings arising in the ordinary course of business. While the ultimate outcome and impact to us cannot be predicted with certainty, we believe that the resolution of these other lawsuits and proceedings will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Guarantees

We have provided certain guarantees, direct and indirect, of the indebtedness of other companies. Under the terms of most of these guarantee arrangements, we would be required to perform should the guaranteed party fail to fulfill its obligations under the specified arrangements. In addition to these financial guarantees, we also have various performance guarantees related to specific agreements.

Guarantees related to indebtedness of equity method investees

LOOP and LOCAP

MPC and MPLX hold interests in an offshore oil port, LOOP, and MPLX holds an interest in a crude oil pipeline system, LOCAP. Both LOOP and LOCAP have secured various project financings with throughput and deficiency agreements. Under

the agreements, MPC, as a shipper, is required to advance funds if the investees are unable to service their debt. Any such advances are considered prepayments of future transportation charges. The duration of the agreements varies but tends to

~~Table of Contents~~

follow the terms of the underlying debt, which extend through 2037. Our maximum potential undiscounted payments under these agreements for the debt principal totaled $171 million as of ~~September 30, 2020.~~

~~Gray Oak Pipeline, LLC~~

In connection with our 25 percent interest in Gray Oak Pipeline, LLC (“Gray Oak Pipeline”), we entered into an Equity Contribution Agreement that obligated us to make certain equity contributions to Gray Oak Pipeline to support its obligations under a construction loan facility. Gray Oak is a crude oil transportation system from West Texas and the Eagle Ford formation to destinations in the Ingleside, Corpus Christi and Sweeney, Texas markets. Gray Oak Pipeline entered into the construction loan facility with a syndicate of banks to finance a portion of the construction costs of the pipeline project.

The Equity Contribution Agreement required us to contribute our pro rata share of any amounts necessary to allow Gray Oak Pipeline to cure any payment defaults under the construction loan facility or to repay all amounts outstanding under the facility, including principal, accrued interest, fees and expenses, in certain circumstances, including the failure of Gray Oak Pipeline to repay or refinance the construction loan facility prior to its scheduled maturity date of June 3, 2022. The construction loan facility was repaid in full with the proceeds of a senior, unsecured notes offering undertaken by Gray Oak Pipeline, and our obligations under the Equity Contribution Agreement automatically terminated during the third quarter of 2020.March 31, 2021.

Dakota Access Pipeline

In connection with MPLX’s 9.19 percent indirect interest in a joint venture (“Dakota Access”) that owns and operates the Dakota Access Pipeline and Energy Transfer Crude Oil Pipeline projects, collectively referred to as the Bakken Pipeline system, MPLX ~~has~~ entered into a Contingent Equity Contribution Agreement. MPLX, along with the other joint venture owners in the Bakken Pipeline system, has agreed to make equity contributions to the joint venture upon certain events occurring to allow the entities that own and operate the Bakken Pipeline system to satisfy their senior note payment obligations. The senior notes were issued to repay amounts owed by the pipeline companies to fund the cost of construction of the Bakken Pipeline system.

In March 2020, the U.S. District Court for the District of Columbia (the “D.D.C.”) ordered the U.S. Army Corps of Engineers (“Army Corps”), which granted permits and an easement for the Bakken Pipeline system, to conduct a full environmental impact statement (“EIS”), and further requested briefing on whether an easement necessary for the operation of the Bakken Pipeline system should be vacated while the EIS is being prepared.

On July 6, 2020, the D.D.C. ordered vacatur of the easement to cross Lake Oahe during the pendency of an EIS and further ordered a shut down of the pipeline by August 5, 2020. The D.D.C. denied a motion to stay that order. Dakota Access and the Army Corps appealed the D.D.C.’s ~~order~~orders to the U.S. Court of Appeals for the District of Columbia Circuit (the “Court of Appeals”). On July 14, 2020, the Court of Appeals issued an administrative stay while the court considered Dakota Access and the Army Corps’ emergency motion for stay pending appeal. On August 5, 2020, the Court of Appeals stayed the D.D.C.’s injunction that required the pipeline be shutdown and emptied of oil by August 5, 2020. The Court of Appeals denied a stay of the D.D.C.’s March order, which required the EIS, and further denied a stay of the D.D.C.’s July order, which vacated the easement. On January 26, 2021, the Court of Appeals upheld the D.D.C.’s order vacating the easement while the Army Corps prepares the EIS. The Court of Appeals reversed the D.D.C.’s order to the extent it directed that the pipeline be shutdown and emptied of oil. In the D.D.C., briefing ~~is ongoing~~has been completed for a renewed request for an ~~injunction, which is expected to be completed by the end of 2020. Oral argument on the merits of the case at the Court of Appeals occurred on November 4, 2020.~~injunction. The pipeline remains operational.

If the pipeline is temporarily shut down pending completion of the EIS, MPLX would have to contribute its 9.19 percent pro rata share of funds required to pay interest accruing on the notes and any portion of the principal that matures while the pipeline is shutdown. It is expected that MPLX would contribute its 9.19 percent pro rata share of any costs to remediate any deficiencies to reinstate the permit and/or return the pipeline into operation. If the vacatur of the easement permit results in a permanent shutdown of the pipeline, MPLX would have to contribute its 9.19 percent pro rata share of the cost to redeem the bonds (including the one percent redemption premium required pursuant to the indenture governing the notes) and any accrued and unpaid interest. As of ~~September 30, 2020,~~March 31, 2021, our maximum potential undiscounted payments under the Contingent Equity Contribution Agreement were approximately $230 million.

Crowley Ocean Partners LLC and Crowley Blue Water Partners LLC

In connection with our 50 percent indirect interest in Crowley Ocean Partners LLC, we have agreed to conditionally guarantee our portion of the obligations of the joint venture and its subsidiaries under a senior secured term loan agreement. The term loan agreement provides for loans of up to $325 million to finance the acquisition of four product tankers. MPC’s liability under the guarantee for each vessel is conditioned upon the occurrence of certain events, including if we cease to maintain an investment grade credit rating or the charter for the relevant product tanker ceases to be in effect and is not replaced by a charter with an investment grade company on certain defined commercial terms. As of ~~September 30, 2020,~~March 31, 2021, our maximum potential undiscounted payments under this agreement for debt principal totaled ~~$119~~$114 million.

~~Table of Contents~~

In connection with our 50 percent indirect interest in Crowley Blue Water Partners LLC, we have agreed to provide a conditional guarantee of up to 50 percent of its outstanding debt balance in the event there is no charter agreement in place with an investment grade customer for the entity’s three vessels as well as other financial support in certain circumstances. As of ~~September 30, 2020,~~March 31, 2021, our maximum potential undiscounted payments under this arrangement was ~~$115~~$111 million.

~~Marathon Oil indemnifications~~

The separation and distribution agreement and other agreements with Marathon Oil to effect our spinoff provide for cross-indemnities between Marathon Oil and us. In general, Marathon Oil is required to indemnify us for any liabilities relating to Marathon Oil’s historical oil and gas exploration and production operations, oil sands mining operations and integrated gas operations, and we are required to indemnify Marathon Oil for any liabilities relating to Marathon Oil’s historical refining, marketing and transportation operations. The terms of these indemnifications are indefinite and the amounts are not capped.

Other guarantees

We have entered into other guarantees with maximum potential undiscounted payments totaling ~~$94~~$99 million as of ~~September 30, 2020,~~March 31, 2021, which primarily consist of a commitment to contribute cash to an equity method investee for certain catastrophic events, in lieu of procuring insurance coverage, a commitment to fund a share of the bonds issued by a government entity for construction of public utilities in the event that other industrial users of the facility default on their utility payments and leases of assets containing general lease indemnities and guaranteed residual values.

~~General guarantees associated with dispositions~~

Table of Contents

Over the years, we have sold various assets in the normal course of our business. Certain of the related agreements contain performance and general guarantees, including guarantees regarding inaccuracies in representations, warranties, covenants and agreements, and environmental and general indemnifications that require us to perform upon the occurrence of a triggering event or condition. These guarantees and indemnifications are part of the normal course of selling assets. We are typically not able to calculate the maximum potential amount of future payments that could be made under such contractual provisions because of the variability inherent in the guarantees and indemnities. Most often, the nature of the guarantees and indemnities is such that there is no appropriate method for quantifying the exposure because the underlying triggering event has little or no past experience upon which a reasonable prediction of the outcome can be based.

Contractual Commitments and Contingencies

At ~~September 30, 2020,~~March 31, 2021, our contractual commitments to acquire property, plant and equipment and advance funds to equity method investees totaled ~~$447~~$396 million.

Certain natural gas processing and gathering arrangements require us to construct natural gas processing plants, natural gas gathering pipelines and NGL pipelines and contain certain fees and charges if specified construction milestones are not achieved for reasons other than force majeure. In certain cases, certain producer customers may have the right to cancel the processing arrangements with us if there are significant delays that are not due to force majeure.

~~CORPORATE OVERVIEW~~

We are a leading, integrated, downstream energy company headquartered in Findlay, Ohio. We own and operate the nation’s largest refining system. Our refineries supply refined products to resellers and consumers across the United States. We distribute refined products to our customers through transportation, storage, distribution and marketing services provided largely by our Midstream segment. We believe we are one of the largest wholesale suppliers of gasoline and distillates to resellers in the United States.

~~We have three strong brands: Marathon~~^®~~, Speedway~~^® ~~and ARCO~~^®. The branded outlets, which primarily operate under the Marathon brand, are established motor fuel brands across the United States available through approximately 7,000 branded outlets operated by independent entrepreneurs in 35 states, the District of Columbia and Mexico. The direct dealer network primarily operates under the ARCO brand, and consists of approximately 1,070 direct dealer locations primarily located in the West Coast region of the United States. As discussed in Recent Developments, we have entered into a sale agreement for our Speedway business.

We primarily conduct our midstream operations through our ownership interest in MPLX, which owns and operates crude oil and refined product transportation and logistics infrastructure and natural gas and NGL gathering, processing, and fractionation

~~Table of Contents~~

assets. As of September 30, 2020, we owned, leased or had ownership interests in approximately 17,200 miles of crude oil and refined product pipelines that deliver crude oil to our refineries and other locations and refined products to wholesale, brand marketing and direct dealer locations. We distribute our refined products through one of the largest terminal operations in the United States and one of the largest private domestic fleets of inland petroleum product barges. Our integrated midstream energy asset network links producers of natural gas and NGLs from some of the largest supply basins in the United States to domestic and international markets. Our midstream gathering and processing operations include: natural gas gathering, processing and transportation; and NGL gathering, transportation, fractionation, storage and marketing.

Our operations consist of two reportable operating segments: Refining & Marketing and Midstream. Each of these segments is organized and managed based upon the nature of the products and services they offer.

•

Refining & Marketing – refines crude oil and other feedstocks at our refineries in the Gulf Coast, Mid-Continent and West Coast regions of the United States, purchases refined products and ethanol for resale and distributes refined products through transportation, storage, distribution and marketing services provided largely by our Midstream segment. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to independent entrepreneurs who operate primarily Marathon^® ~~branded outlets, through long-term fuel supply contracts with direct dealers who operate locations mainly under the ARCO~~^® ~~brand and to approximately 3,900 Speedway locations.~~


•	Midstream – transports, stores, distributes and markets crude oil and refined products principally for the Refining & Marketing segment via refining logistics assets, pipelines, terminals, towboats and barges; gathers, processes and transports natural gas; and gathers, transports, fractionates, stores and markets NGLs. The Midstream segment primarily reflects the results of MPLX.

~~Recent Developments~~

~~Strategic Actions to Enhance Shareholder Value~~

On August 2, 2020, we entered into a definitive agreement to sell Speedway, our company-owned and operated retail transportation fuel and convenience store business, to 7-Eleven, Inc. for $21 billion in cash, subject to certain adjustments based on the levels of cash, debt (as defined in the agreement) and working capital at closing and certain other items. The taxable transaction is expected to close in the first quarter of 2021, subject to customary closing conditions and regulatory approvals. This transaction is expected to result in after-tax cash proceeds of approximately $16.5 billion. The company expects to use the proceeds from the sale to strengthen the balance sheet and return capital to shareholders. We will retain our direct dealer business.

In connection with the agreement to sell Speedway, the Company has agreed to enter into certain ancillary agreements, including a 15-year fuel supply agreement for approximately 7.7 billion gallons per year associated with 7-Eleven, Inc. or its subsidiaries. Further, the Company expects incremental opportunities over time to supply 7-Eleven's remaining business as existing arrangements mature and as new locations are added in connection with its announced U.S. and Canada growth strategy.

As a result of the agreement to sell the Speedway business, its results are reported separately as discontinued operations in our consolidated statements of income for all periods presented and its assets and liabilities have been reclassified in our consolidated balance sheets to assets and liabilities held for sale. Prior to presentation of Speedway as discontinued operations, Speedway and our retained direct dealer business were the two reporting units within our Retail segment. Beginning with the third quarter of 2020, the direct dealer business is managed as part of the Refining & Marketing segment. The results of the Refining & Marketing segment have been retrospectively adjusted to include the results of the direct dealer business in all periods presented.

~~As a result of our agreement to sell Speedway, the following changes in our basis of presentation have occurred:~~

EXECUTIVE SUMMARY

Business Update

The outbreak of COVID-19 and its development into a pandemic in March 2020 ~~have~~ resulted in significant economic disruption globally. Actions taken by various governmental authorities, individuals and companies around the world to prevent the spread of COVID-19 through social distancing ~~have~~ restricted travel, many business operations, public gatherings and the overall level of individual movement and in-person interaction across the ~~globe.~~

~~This has in turn significantly reduced global economic activity and~~globe resulted in ~~a decrease~~dramatic reductions in airline flights and motor vehicle use ~~at a time when seasonal driving patterns typically result~~ in ~~an increase of consumer~~2020 as compared to prior to the pandemic.

As we begin 2021, while demand ~~for gasoline and a dramatic reduction in airline flights. As a result, there has also been a decline~~remains below historical levels, we continue to see gradual recovery in the ~~demand~~environment in which our business operates, albeit in some markets and regions more or less than others. The increased availability of vaccinations and the corresponding reductions in travel and business restrictions appears to be driving increased economic activity, including the opening of many business and schools as well as more in-person interaction broadly.

In response to this business environment, we continue to focus on three near-term priorities for ~~the refined petroleum products~~our businesses:

Strengthen Competitive Position of Assets

We are committed to positioning our assets so that we ~~manufacture~~are a leader in operational, financial, and ~~sell.~~sustainability performance and are evaluating the strength and fit of assets in our portfolio. Our goal is that each individual asset generates free-cash-flow back to the business and contributes to shareholder returns. With our investments we are focused on high returning projects that we believe will enhance the competitiveness of our portfolio, including our investments in sustainable fuels and technologies that lower our carbon intensity as the global energy mix evolves.

Lower Cost Structure

We are committed to achieving operational excellence by reducing costs, improving efficiency and driving operational improvements. In response to the pandemic, in March of 2020, we committed to immediately reducing our capital spending and operating expenses. In 2021, we are continuing this focus with planned reductions of over $200 million for ~~refined petroleum products coupled with a decline in the price of crude oil has resulted in a significant decrease in the price~~our capital expenditures and ~~volume of the refined petroleum products we produce~~investments as compared to 2020 (excluding capitalized interest, potential acquisitions and ~~sell and had a negative impact on working~~MPLX’s capital ~~during the first nine months of 2020.~~investment plan).

In ~~addition, a decline~~connection with our commitment to lower cost, in the market prices for products held in our inventories below the carrying value of our inventory resulted in an adjustment to the value of our inventories. At September 30, 2020, market values for these inventories were lower than their LIFO cost basis and, as a result, we recorded an LCM inventory valuation reserve of $1.19 billion. Based on movements of refined product prices, future inventory valuation adjustments could have a negative or positive effect to earnings. Such losses are subject to reversal in subsequent periods if prices recover.

~~We have been and continue to actively respond to the impacts that these matters are having on our business. During~~ the third quarter of 2020 we announced strategic actions to lay a foundation for long-term success, including plans to optimize our assets and structurally lower costs in 2021 and ~~beyond, which~~beyond. These actions included indefinitely idling the Gallup ~~and~~refinery, initiating actions to strategically reposition the Martinez ~~refineries~~refinery to a renewable diesel facility and the approval of an involuntary workforce reduction plan. ~~In connection with these strategic actions, we recorded restructuring expenses of~~ ~~$348 million~~ for the three months ended September 30, 2020. We also progressed activities associated with the conversion of the Martinez refinery to a renewable diesel facility, including applying for permits, advancing discussions with feedstock suppliers, and beginning detailed engineering activities. As envisioned, the Martinez facility would be expected to start producing renewable diesel in 2022, with a potential to build to full capacity of 48,000 barrels per day in 2023.

We previously announced a goal to reduce capital spending by $1.35 billion, resulting in planned 2020 capital spending of $3.0 billion, or a reduction of approximately 30 percent from our initial plan for the year. We are currently on track to exceed this targeted reduction. The reductions are planned across all segments of the business. Our ~~remaining capital spend primarily relates to growth projects that are already in progress or spending that supports the safe and reliable operation of our facilities.~~

We are also on track to exceed our targeted $950 million reduction of 2020 forecasted operating expenses, primarily through reductions of fixed costs and deferral of certain expense projects, which includes $200 million of operating expense reductions at MPLX.

~~In addition to these measures to address our operations, earlier~~results in the ~~year we took action to address our liquidity as outlined below:~~

~~Share repurchases have temporarily been suspended. The timing and amount~~first quarter of ~~future repurchases, if any, will depend upon several factors, including market and business conditions.~~

~~On April 27, 2020, we entered into an additional $1.0 billion 364-day revolving credit facility, which expires in~~ 2021 ~~to provide incremental liquidity and financial flexibility during~~reflect the ~~commodity price and demand downturn.~~

~~On April 27, 2020, we closed on the issuance of $2.5 billion of senior notes. Proceeds~~favorable effects from ~~the senior notes were used to pay down certain amounts outstanding on the five-year revolving credit facility.~~

~~During June 2020, we repaid the remaining amounts outstanding on the five-year revolving credit facility.~~

On September 23, 2020, we entered into a 364-day revolving credit agreement, which provides for a $1.0 billion unsecured revolving credit facility that matures in September 2021, and which replaces a similar 364-day revolving credit agreement that expired on September 28, 2020. At September 30, 2020, we had $7.7 billion available on our variable credit facilities.these cost reduction actions.

Many uncertainties remain with respect to COVID-19, including its resulting economic effects, and we are unable to predict the ultimate economic impacts from COVID-19 and how quickly national economies can recover once the pandemic ultimately subsides. However, the adverse impact of the economic effects on MPC has been and will likely continue to be significant. We believe we have proactively addressed many of the known impacts of COVID-19 to the extent possible and will strive to continue to do so, but there can be no guarantee the measures will be fully effective.

Other Strategic Updates

On July 31, 2020, Western Refining Southwest, Inc. (“WRSW”), a wholly owned subsidiary of MPC, entered into a Redemption Agreement (the “Redemption Agreement”) with MPLX, pursuant to which MPLX transferred to WRSW all of the outstanding membership interests in Western Refining Wholesale, LLC (“WRW”), in exchange for the redemption of MPLX common units valued at $340 million held by WRSW. The transaction resulted in a minor decrease in MPC’s ownership interest in MPLX. Beginning in the third quarter of 2020, the results of these operations are presented in the Refining & Marketing segment.

On November 2, 2020, MPLX announced the board authorization of a unit repurchase program for the repurchase of up to $1 billion of MPLX’s outstanding common units held by the public. MPLX may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block transactions, tender offers, accelerated unit repurchases or open market solicitations for units, some of which may be effected through Rule 10b5-1 plans. The timing and amount of repurchases, if any, will depend upon several factors, including market and business conditions, and repurchases may be initiated, suspended or discontinued at any time. The repurchase authorization has no expiration date.

~~On March 18, 2020, we announced that~~February 24, 2021, MPC’s board of directors ~~unanimously decided~~approved our plan to ~~maintain MPC’s current midstream structure,~~strategically reposition the Martinez refinery to a renewable diesel facility. Converting the Martinez facility from refining petroleum to manufacturing renewable fuels signals our strong commitment to producing a substantial level of lower carbon-intensity fuels in California. As envisioned, the Martinez facility would start producing approximately 260 million gallons per year of renewable diesel by the second half of 2022, with ~~MPC remaining, through~~ a ~~wholly owned subsidiary,~~potential to build to full capacity of approximately 730 million gallons per year by the ~~general partner~~end of ~~MPLX. This decision concluded a comprehensive evaluation, led~~2023.

The Dickinson, North Dakota, renewable fuels facility began ramping operations at the end of 2020 and is on track to reach full production by ~~a special committee~~the end of the ~~board, that included extensive input~~second quarter of 2021. At full capacity, the facility is expected to produce 184 million gallons per year of renewable diesel from ~~multiple external advisors~~corn and ~~significant feedback~~soybean oil. MPC is selling the renewable diesel into the California market to comply with the California Low Carbon Fuel Standard.

On August 2, 2020, we entered into a definitive agreement to sell Speedway, our company-owned and operated retail transportation fuel and convenience store business, to 7-Eleven, Inc. for $21 billion in cash, subject to certain adjustments based on the levels of cash, debt and working capital at closing and certain other items. The taxable transaction is expected to close in the second quarter of 2021, subject to customary closing conditions and the receipt of regulatory approvals. 7-Eleven and MPC continue to engage productively with the Federal Trade Commission in its review of the transaction.This transaction is expected to result in after-tax cash proceeds of approximately $16.5 billion. The company expects to use the proceeds from ~~investors.~~the sale to strengthen the balance sheet and return capital to shareholders.

In connection with the agreement to sell Speedway, we have agreed to enter into certain ancillary agreements, including 15-year fuel supply agreements associated with 7-Eleven or its subsidiaries, depending on the fuel demand of Speedway and other factors to be set forth in the fuel supply agreement. Further, we expect incremental opportunities over time to supply 7-Eleven’s remaining business as 7-Eleven’s existing arrangements mature and as new locations are added in connection with its announced U.S. and Canada growth strategy.

Actions taken by various governmental authorities, individuals and companies to prevent the spread of COVID-19 through social distancing have restricted travel, many business operations, public gatherings and the overall level of individual movement and in-person interaction in the areas where we operate which has impacted demand for our products. Net ~~income (loss)~~loss attributable to MPC was ~~$(886)~~$(242) million, or ~~$(1.36) per diluted share, in the third quarter of 2020 compared to $1.10 billion, or $1.66 per diluted share, for the third quarter of 2019 and $(10.11) billion, or $(15.58)~~$(0.37) per diluted share, in the first ~~nine months~~quarter of ~~2020~~2021 compared to ~~$2.19~~$(9.23) billion, or ~~$3.28~~$(14.25) per diluted share, for the first quarter of 2020, largely due to the absence of impairment expenses and an LCM inventory charge in the first ~~nine~~three months of ~~2019.~~

For the third quarter of 2020, the change in net income (loss) attributable to MPC was largely due to a loss in our Refining & Marketing segment, long-lived asset impairment charges of $433 million, in addition to ~~restructuring expenses of~~ ~~$348 million related to the idling of the Martinez and Gallup refineries and costs related to our announced workforce reduction.~~2021. These ~~changes~~effects were partially offset by a $530 million LCM benefit recognized in the quarter. The loss from operations in our Refining & Marketing segment is primarily due to decreases in refined product sales volumes, prices and margins during the current period and includes a charge of $256 million for the three months ended September 30, 2020 to reflect an expected LIFO liquidation for our crude oil inventories. These results were partially offset by increaseddecreased income from discontinued operations, which relates to the Speedway business, in the ~~third~~first quarter of 2020 compared to the third quarter of 2019 mainly due to higher fuel margin and merchandise sales and lower operating and depreciation and amortization expenses, partially offset by lower fuel volumes.

For the first nine months of 2020, the change in net income (loss) attributable to MPC was primarily due to a loss in our Refining & Marketing segment, goodwill and long-lived asset impairment charges of $8.28 billion and impairments of equity method investments of $1.32 billion during the period primarily driven by the effects of COVID-19 and the decline in commodity prices, an LCM charge of $1.19 billion and ~~restructuring expenses of~~ $348 million related to the idling of the Martinez and Gallup refineries and costs related to our announced workforce reduction. The loss from operations in our Refining & Marketing segment is primarily due to decreases in refined product sales volumes, prices and margins during the current period and includes a charge of $256 million for the nine months ended September 30, 2020 to reflect an expected LIFO liquidation for our crude oil inventories. The costs of inventories in the historical LIFO layer which is expected to be liquidated are higher than current costs, which resulted in increased cost of revenues and decreased income from operations. These results were partially offset by increased income from discontinued operations, which relates to the Speedway business,

MPLX

We owned approximately 647 million MPLX common units at ~~September 30, 2020~~March 31, 2021 with a market value of ~~$10.19~~$16.59 billion based on the ~~September 30, 2020~~March 31, 2021 closing price of ~~$15.74~~$25.63 per common unit. On ~~October~~April 27, ~~2020,~~2021, MPLX declared a quarterly cash distribution of $0.6875 per common unit payable on ~~November 13, 2020.~~May 14, 2021. As a result, MPLX will make distributions totaling ~~$715~~$707 million to its common unitholders. MPC’s portion of these distributions is approximately $445 million.

We received limited partner distributions of ~~$1.35 billion~~$445 million from MPLX in the ~~nine~~three months ended ~~September 30, 2020~~March 31, 2021 and ~~$1.39 billion from MPLX and ANDX combined~~$446 million in the ~~nine~~three months ended ~~September 30, 2019. The decrease in distributions from~~March 31, 2020.

During the ~~prior year is due to the fact that ANDX had a higher per unit distribution prior to the Merger when compared to the MPLX distribution per unit post-merger.~~

~~On July~~three months ended March 31, 2020, WRSW, a wholly owned subsidiary of MPC, entered into a Redemption Agreement with MPLX, pursuant to which MPLX agreed to transfer to WRSW, all of the outstanding membership interests in WRW in exchange for the redemption of2021, 6,272,981 MPLX common units ~~held by WRSW. The transaction effects~~had been repurchased at an average cost per unit of $24.78. Total cash paid for units repurchased during the ~~transfer~~three months ended March 31, 2021 was $155 million. As of March 31, 2021, MPLX had agreements to MPC of the Western wholesale distribution business that MPLX acquired as a result of its acquisition of ANDX. Beginning in the third quarter of 2020, the results of these operations are presented in MPC’s Refining & Marketing segment prospectively.

~~At the closing, per the terms of Redemption Agreement, MPLX redeemed 18,582,088 MPLX~~acquire 291,400 additional common units ~~(the “Redeemed Units”) held by WRSW. The number~~for $7 million, which settled in early April 2021.

OVERVIEW OF SEGMENTS

Refining & Marketing

Refining & Marketing segment income from operations depends largely on our Refining & Marketing margin, refining operating costs, refining planned turnarounds, distribution costs, ~~refining planned turnaround~~depreciation expenses and refinery throughputs.

Our Refining & Marketing margin is the difference between the prices of refined products sold and the costs of crude oil and other charge and blendstocks refined, including the costs to transport these inputs to our refineries and the costs of products purchased for resale. The crack spread is a measure of the difference between market prices for refined products and crude oil, commonly used by the industry as a proxy for the refining margin. Crack spreads can fluctuate significantly, particularly when prices of refined products do not move in the same direction as the cost of crude oil. As a performance benchmark and a comparison with other industry participants, we calculate Gulf Coast, Mid-Continent and West Coast crack spreads that we believe most closely track our operations and slate of products. The following are used for these crack-spread calculations:

•The Gulf Coast crack spread uses three barrels of ~~LLS~~MEH crude producing two barrels of USGC CBOB gasoline and one barrel of USGC ~~ULSD;~~ULSD. In the first quarter of 2021, we transitioned to MEH crude from LLS crude;

•The Mid-Continent crack spread uses three barrels of WTI crude producing two barrels of Chicago CBOB gasoline and one barrel of Chicago ULSD; and

•The West Coast crack spread uses three barrels of ANS crude producing two barrels of LA CARBOB and one barrel of LA CARB Diesel.

Our refineries can process significant amounts of sweet and sour crude oil, which typically can be purchased at a discount to crude oil referenced in our Gulf Coast, Mid-Continent and West Coast crack spreads. The amount of these discounts, which we refer to as the sweet differential and sour differential, can vary significantly, causing our Refining & Marketing margin to differ from blended crack spreads. In general, larger sweet and sour differentials will enhance our Refining & Marketing margin.

Future crude oil differentials will be dependent on a variety of market and economic factors, as well as U.S. energy policy.

In addition to the market changes indicated by the crack spreads, the sour differential and the sweet differential, our Refining & Marketing margin is impacted by factors such as:

•the selling prices realized for refined products;

•the types of crude oil and other charge and blendstocks processed;

•our refinery yields;

•the cost of products purchased for resale; ~~and~~

•the impact of commodity derivative instruments used to hedge price ~~risk.~~risk;

•the potential impact of LCM adjustments to inventories in periods of declining prices; and

•the potential impact of LIFO liquidation charges due to draw-downs from historic inventory levels.

Refining & Marketing segment income from operations is also affected by changes in refinery operating costs and refining planned turnaround costs in addition to committed distribution costs. Changes in operating costs are primarily driven by the cost of energy used by our refineries, including purchased natural gas, and the level of maintenance costs. Refining planned

turnarounds, requiring temporary shutdown of certain refinery operating units, are periodically performed at each refinery. Distribution costs primarily include long-term agreements with MPLX, which as discussed below ~~which are based on committed volumes~~include minimum commitments to MPLX, and will negatively impact income from operations in periods when throughput or sales are lower or refineries are idled.

We have various long-term, fee-based commercial agreements with MPLX. Under these agreements, MPLX, which is reported in our Midstream segment, provides transportation, storage, distribution and marketing services to our Refining & Marketing segment. Certain of these agreements include commitments for minimum quarterly throughput and distribution volumes of crude oil and refined products and minimum storage volumes of crude oil, refined products and other products. Certain other agreements include commitments to pay for 100 percent of available capacity for certain marine transportation and refining logistics assets.

Midstream

Our Midstream segment transports, stores, distributes and markets crude oil and refined products, principally for our Refining & Marketing segment. The profitability of our pipeline transportation operations primarily depends on tariff rates and the volumes shipped through the pipelines. The profitability of our marine operations primarily depends on the quantity and availability of our vessels and barges. The profitability of our light product terminal operations primarily depends on the throughput volumes at these terminals. The profitability of our fuels distribution services primarily depends on the sales volumes of certain refined products. The profitability of our refining logistics operations depends on the quantity and availability of our refining logistics assets. A majority of the crude oil and refined product shipments on our pipelines and marine vessels and the refined product throughput at our terminals serve our Refining & Marketing segment and our refining logistics assets and fuels distribution services are used solely by our Refining & Marketing segment. As discussed above in the Refining & Marketing section, MPLX, which is reported in our Midstream segment, has various long-term, fee-based commercial agreements related to services provided to our Refining & Marketing segment. Under these agreements, MPLX has received various commitments of minimum throughput, storage and distribution volumes as well as commitments to pay for all available capacity of certain assets. The volume of crude oil that we transport is directly affected by the supply of, and refiner demand for, crude oil in the markets served directly by our crude oil pipelines, terminals and marine operations. Key factors in this supply and demand balance are the production levels of crude oil by producers in various regions or fields, the availability and cost of alternative modes of transportation, the volumes of crude oil processed at refineries and refinery and transportation system maintenance levels. The volume of refined products that we transport, store, distribute and market is directly affected by the production levels of, and user demand for, refined products in the markets served by our refined product pipelines and marine operations. In most of our markets, demand for gasoline and distillate peaks during the summer driving season, which extends from May through September of each year, and declines during the fall and winter months. As with crude oil, other transportation alternatives and system maintenance levels influence refined product movements.

Our Midstream segment also gathers and processes natural gas and NGLs. NGL and natural gas prices are volatile and are impacted by changes in fundamental supply and demand, as well as market uncertainty, availability of NGL transportation and fractionation capacity and a variety of additional factors that are beyond our control. Our Midstream segment profitability is affected by prevailing commodity prices primarily as a result of processing or conditioning at our own or third‑party processing plants, purchasing and selling or gathering and transporting volumes of natural gas at index‑related prices and the cost of third‑party transportation and fractionation services. To the extent that commodity prices influence the level of natural gas drilling by our producer customers, such prices also affect profitability.

~~Third~~First Quarter 2021 Compared to First Quarter 2020 ~~Compared to Third Quarter 2019~~

Net ~~income (loss)~~loss attributable to MPC decreased ~~$1.98~~$8.99 billion in the ~~third~~first quarter of 2021 compared to the first quarter of 2020 ~~compared to the third quarter of 2019~~ largely due to ~~a decrease~~the absence of impairment expenses and an LCM inventory charge in the first three months of 2021.

Revenues and other income increased $1.89 billion primarily due to:

•increased sales and other operating revenues of $507 million primarily due to increased Refining & Marketing segment average refined product sales prices of $0.24 per gallon, partially offset by decreased refined product sales volumes ~~prices~~of 521 mbpd;

•increased income from equity method investments mainly due to impairment expense of $1.32 billion recorded in the first quarter of 2020 primarily driven by the effects of COVID-19 and ~~margin,~~the decline in commodity price in the prior year; and

•increased other income of $54 million primarily due to higher income on RIN sales.

•increased cost of revenues of $742 million mainly due to higher crude oil costs;

•the absence of an LCM inventory valuation charge in the first quarter of 2021 compared to a charge of $3.19 billion in the first quarter of 2020 primarily driven by the effects of COVID-19 and the decline in commodity price in the prior year;

•decreased impairment expense of $7.82 billion due to impairments recorded for goodwill and long-lived assets in the first quarter of 2020 primarily driven by the effects of COVID-19 and the decline in commodity prices $433 million of long-lived assets impairment primarily related to the repositioning of our Martinez refinery, $348 million of restructuring expenses and a $256 million charge to reflect an expected LIFO liquidation for our crude oil inventories. These charges were partially offset by an LCM benefit of $530 million and increased income from discontinued operations, which represents our Speedway business.

~~Table of Contents~~

Revenues and other income decreased $10.14 billion primarily due to decreased Refining & Marketing segment refined product sales volumes, which decreased 505 mbpd, and decreased average refined product sales prices of $0.55 per gallon largely due to reduced travel and business operations associated with the COVID-19 pandemic.

~~Costs and expenses decreased $7.40 billion primarily due to:~~

decreased cost of revenues of $7.67 billion mainly due to lower refined product sales volumes, which decreased 505 mbpd primarily due to reduced travel and business operations associated with the COVID-19 pandemic and an LCM benefit of $530 million.

restructuring expenses of $348 million related to the idling of the Martinez and Gallup refineries and costs related to our announced workforce reduction. See Note 3 to the unaudited consolidated financial statements for additional information; and

increased other taxes of $37 million primarily due to increased property and environmental taxes of approximately $21 million and $17 million, respectively. Property taxes increased in the current period mainly due to the absence of tax exemptions and property tax refunds received in the third quarter of 2019 and environmental taxes increased largely due to the reinstatement of the Oil Spill Tax in 2020, which was not in effect for all of 2019.

~~Net interest and other financial costs increased $47~~$167 million largely due to ~~increased MPC borrowings~~cost reductions realized from our 2020 workforce reduction and ~~decreased capitalized interest and interest income.~~other cost control efforts.

Benefit for income taxes on continuing operations was $436 million for the three months ended September 30, 2020 compared to provision for income taxes on continuing operations of $255 million for the three months ended September 30, 2019.

Our effective tax benefit rate for the three months ended ~~September 30,~~March 31, 2020 was higher than the U.S. statutory rate of 21 percent due to certain permanent tax benefits related to net income attributable to noncontrolling interests, state taxes, and a change in estimate related to the expected NOL carryback provided by the CARES Act offset by non-tax deductible goodwill impairment. The combined federal, state and foreign continuing operations income tax rate for the three months ended September 30, 2019 and was less than the U.S. statutory rate of 21 percent primarily due to certain permanent tax differences related to net income attributable to noncontrolling interests offset by equity compensation and state and local tax expense.

~~Nine Months Ended September 30, 2020 Compared to Nine Months Ended September 30, 2019~~

Net income (loss) attributable to MPC decreased $12.31 billion in the first nine months of 2020 compared to the first nine months of 2019 primarily due to impairment expenses for goodwill and long-lived assets of $8.28 billion, impairments of equity method investments of $1.32 billion, an LCM charge of $1.19 billion, decreased refined product sales volumes, prices and margin, restructuring expenses of $348 million, and a charge of $256 million to reflect an expected LIFO liquidation in our crude oil inventories. These changes were partially offset by increased income from discontinued operations, which represents our Speedway business.

~~Revenues and other income decreased $32.88 billion primarily due to:~~

decreased sales and other operating revenues of $31.33 billion primarily due to decreased Refining & Marketing segment refined product sales volumes, which decreased 508 mbpd, and decreased average refined product sales prices of $0.56 per gallon primarily due to reduced travel and business operations associated with the COVID-19 pandemic;

decreased income from equity method investments of $1.31 billion largely due to impairments of equity method investments of $1.32 billion primarily driven by the effects of COVID-19 and the decline in commodity prices; and

decreased net gain on disposal of assets of $214 million mainly due to the absence of a $207 million gain recognized in 2019 in connection with MPC’s exchange of its undivided interest in the Capline pipeline system for an equity ownership in Capline LLC.

It also includes impairment of long-lived assets primarily related to the repositioning of the Martinez refinery;

decreased selling, general and administrative expenses of $333 million mainly due to decreases in salaries and employee-related expenses, transaction-related expenses, credit card processing fees for brand customers and litigation expense, partially offset by increases in employee benefit costs and other expenses;

restructuring expense of $348 million related to the idling of the Martinez and Gallup refineries and costs related to our announced workforce reduction. See Note 3 to the unaudited consolidated financial statements for additional information; and

increased other taxes of $139 million primarily due to increased property and environmental taxes of approximately $77 million and $56 million, respectively. Property taxes increased in the current period mainly due to the absence of property tax refunds and tax exemptions received in the first nine months of 2019 and environmental taxes increased largely due to the reinstatement of the Oil Spill Tax in 2020, which was not in effect for all of 2019.

~~Net interest and other financial costs increased $100 million largely due to increased MPC borrowings and foreign currency exchange losses and decreased interest income.~~

Benefit for income taxes on continuing operations was $2.24 billion for the nine months ended September 30, 2020 compared to provision for income taxes on continuing operations of $600 million for the nine months ended September 30, 2019, mainly due to decreased income before income taxes of $16.64 billion. The combined federal, state and foreign income tax rate was 16 percent (tax rate benefit) and 20 percent for the nine months ended September 30, 2020 and 2019, respectively. The effective tax rate for the nine months ended September 30, 2020 was lower than the U.S. statutory rate ~~of 21 percent~~ primarily due to a significant amount of our pre-tax loss consisting of non-tax deductible goodwill impairment ~~charges, partially offset by the tax rate differential resulting from the expected NOL carryback provided under the CARES Act.~~charges. Additionally, our effective tax rate is generally benefited by our noncontrolling interest in MPLX, but this benefit was lower for the ~~nine~~three months ended ~~September 30,~~March 31, 2020 ~~compared to the nine months ended September 30, 2019~~ due to ~~goodwill and other~~ impairment charges recorded by MPLX. The effective tax rate for the nine months ended September 30, 2019 was less than the U.S. statutory rate of 21 percent primarily due to $36 million of state deferred tax expense recorded as an out of period adjustment, offset by permanent tax differences related to net income attributable to noncontrolling interests.

~~Nine Months Ended September 30, 2020 Compared to Nine Months Ended September 30, 2019~~

Income from discontinued operations, net of tax, increased $260 million primarily due to higher fuel margin partially offset by lower fuel volumes. Changes in fuel sales volumes were primarily due to the effects of the COVID-19 pandemic which resulted in restricted travel, social distancing and reduced business operations. In addition, fuel sales volumes decreased as a result of an agreement between Speedway and PTC, effective October 1, 2019, in which PTC supplies, prices and sells diesel fuel at certain Speedway and PTC locations with both companies sharing in the diesel fuel margins.

Beginning August 2, 2020, in accordance with ASC 360, Property, Plant, and Equipment, we ceased recording depreciation and amortization for the Speedway business’ property, plant and equipment, finite-lived intangible assets and right of use lease assets. As a result, Speedway depreciation and amortization was $237 million and $285 million for the nine months ended September 30, 2020 and 2019, respectively.

~~Third~~First Quarter 2021 Compared to First Quarter 2020 ~~Compared to Third Quarter 2019~~

Refining & Marketing segment revenues ~~decreased $10.13 billion~~increased $380 million primarily due to increased average refined product sales prices of $0.24 per gallon, partially offset by lower refined product sales volumes, which decreased 505 mbpd, and decreased average refined product sales prices of $0.55 per gallon. These decreases were primarily the result of reduced travel and business operations associated with the COVID-19 pandemic.521 mbpd.

Net refinery throughputs decreased ~~620~~429 mbpd during the ~~third~~first quarter of ~~2020,~~2021, primarily due to reducing throughputs and indefinitely idling certain facilities during the COVID-19 pandemic.

Refining & Marketing segment income from operations decreased ~~$2.56 billion~~$101 million primarily due to lower blended crack ~~spreads.~~spreads, partially offset by reduced refining operating, distribution, and refining planned turnaround costs.

Refining & Marketing margin ~~excluding LIFO liquidation charge,~~ was ~~$8.28~~$10.16 per barrel for the ~~third~~first quarter of ~~2020~~2021 compared to ~~$15.11~~$11.86 per barrel for the ~~third~~first quarter of ~~2019.~~2020. Refining & Marketing margin is affected by our performance against the market indicators shown earlier, which use spot market values and an estimated mix of crude purchases and product sales. Based on the market indicators and our crude oil throughput, we estimate a net negative impact of approximately ~~$3 billion~~$700 million on Refining & Marketing margin for the ~~third~~first quarter of ~~2020~~2021 compared to the ~~third~~first quarter of ~~2019,~~2020, primarily due to lower volumes and crack ~~spreads.~~spreads and narrower sour crude oil differentials. Our reported Refining & Marketing margin differs from market indicators due to the mix of crudes purchased and their costs, the effect of market structure on our crude oil acquisition prices, the effect of RIN prices on the crack spread, and other items like refinery yields, other feedstock variances ~~direct dealer~~and fuel margin ~~and, for the third quarter of 2020, a LIFO liquidation charge of $256 million.~~from sales to direct dealers.

economic effects of COVID-19, including operating at lower throughput at our refineries and idling portions of our refining capacity. This decrease was partially offset by increased turnaround and distribution costs, excluding depreciation and amortization, of $70 million and $53 million, respectively. Net refinery throughput was 620 mbpd lower as compared to the three months ended September 30, 2019. On a per barrel basis, refining operating costs, excluding depreciation and amortization, decreased $0.03 primarily due to lower throughput partially offset by decreased costs. Distribution costs, excluding depreciation and amortization, increased $1.29 per barrel, primarily due to lower throughput. Distribution costs, excluding depreciation and amortization, include fees paid to MPLX of $889 million and $794 million for the third quarter ofMarch 31, 2020 and 2019, respectively. Refining planned turnaround costs increased $0.45 per barrel due to the timing of turnaround activity and lower throughput. Depreciation and amortization per barrel increased by $0.41 per barrel primarily due to lower throughput and increased costs.

~~Nine Months Ended September 30, 2020 Compared to Nine Months Ended September 30, 2019~~

Refining & Marketing segment revenues decreased $31.17 billion primarily due to lower refined product sales volumes, which decreased 508 mbpd, and decreased average refined product sales prices of $0.56 per gallon. These decreases were primarily the result of reduced travel and business operations associated with the COVID-19 pandemic.

~~Net refinery throughputs decreased 524 mbpd in the first nine months of 2020, primarily due to reducing throughputs and indefinitely idling certain facilities during the COVID-19 pandemic.~~

~~Refining & Marketing segment income from operations decreased $5.36 billion primarily driven by lower blended crack spreads.~~

Refining & Marketing margin is affected by the market indicators shown earlier, which use spot market values and an estimated mix of crude purchases and product sales. Based on the market indicators and our crude oil throughput, we estimate a net negative impact of approximately $7 billion on Refining & Marketing margin for the first nine months of 2020 compared to the first nine months of 2019, primarily due to lower crack spreads.Our reported Refining & Marketing margin differs from market indicators due to the mix of crudes purchased and their costs, market structure on our crude oil acquisition prices, RIN prices on the crack spread, and other items like refinery yields, other feedstock variances, direct dealer fuel margin and, for the third quarter of 2020, a LIFO liquidation charge of $256 million. These factors had an estimated net positive effect of approximately $1.4 billion on Refining & Marketing segment income in the first nine months of 2020 compared to the first nine months of 2019.

For the nine months ended September 30, 2020, refining operating and distribution costs, excluding depreciation and amortization, were $7.99 billion. This was a decrease of $499 million compared to the nine months ended September 30, 2019 as we took actions to reduce costs in response to the economic effects of COVID-19, including operating at lower throughput at our refineries and idling portions of our refining capacity. ~~This decrease was partially offset by increased refining planned turnaround~~

See Note 4 to the unaudited consolidated financial statements for additional information on discontinued operations. 2019 costs include employee severance, retention and other costs related to the acquisition of Andeavor.

~~Third Quarter 2020 Compared to Third Quarter 2019~~

~~Corporate costs decreased $9 million.~~ ~~Third~~ ~~quarter~~ ~~2020~~ ~~and~~ ~~2019~~ ~~corporate expenses include expenses of $7 million and $8 million, respectively, which are no longer allocable to Speedway due to discontinued operations accounting.~~

~~During the third quarter of~~Midstream strategic review. Costs incurred in 2020 ~~we announced strategic actions to lay a foundation for long-term success, including plans to optimize our assets and structurally lower costs~~ in ~~2021 and beyond, which included indefinitely idling the Gallup and Martinez refineries and the approval of an involuntary workforce reduction plan. In~~ connection with ~~these strategic actions, we recorded restructuring expenses of $348 million~~the Speedway separation are included in discontinued operations. See Note 3 to the unaudited consolidated financial statements for ~~the three months ended September 30, 2020~~additional information on discontinued operations.

The involuntary workforce reduction plan, including employee reductions resulting from MPC's indefinite idling of its Martinez and Gallup refineries, affected approximately 2,050 employees. We recorded $159 million of restructuring expenses for separation benefits payable under our employee separation plan and certain collective bargaining agreements that we expect to settle in cash. Certain of the affected MPC employees provide services to MPLX. MPLX has various employee services agreements and secondment agreements with MPC pursuant to which MPLX reimburses MPC for employee costs, along with

~~Table of Contents~~

the provision of operational and management services in support of MPLX’s operations. Pursuant to such agreements, MPC was reimbursed by MPLX for $36 million of the $159 million of restructuring expenses recorded for these actions.

As of September 30, 2020, $291 million of restructuring expenses were accrued as restructuring reserves in our consolidated balance sheet and we expect cash payments for the majority of these reserves to occur within the next twelve months.

~~The change from the LCM inventory valuation reserve at June 30, 2020 resulted in a benefit of $530 million for the three months ended September 30, 2020.~~

~~Transaction-related costs of $22 million for the third quarter of 2019 largely related to employee retention, severance and other costs associated with the Andeavor acquisition.~~

~~Nine Months Ended September 30, 2020~~First Quarter 2021 Compared to ~~Nine Months Ended September 30, 2019~~

~~Corporate costs increased $36 million primarily due to an information systems integration project. The first nine months of~~ First Quarter 2020 ~~and~~ ~~2019~~ ~~corporate expenses include expenses of $20 million and $21 million, respectively, which are no longer allocable to Speedway due to discontinued operations accounting.~~

During the first ~~nine months~~quarter of 2020, we recorded impairment charges of approximately ~~$9.60~~$9.14 billion, which includes ~~$8.28~~$7.82 billion related to goodwill and long-lived assets and ~~$1.32 billion related to~~impairments of equity method investments of $1.32 billion, and an ~~LCM~~inventory market valuation adjustment charge of ~~$1.19~~$3.19 billion primarily driven by the effects of COVID-19 and the decline in commodity prices.

Items not allocated to segments also include transaction-related costs of $8 million for the first nine months of 2020 associated with the Midstream strategic review and other related activities and $147 million for the first nine months of 2019 largely related to the recognition of an obligation for vacation benefits provided to former Andeavor employees as part of the Andeavor acquisition as well as employee retention, severance and other costs. Transaction costs for the first nine months of 2020 related to the Speedway separation are included in discontinued operations. In the first nine months of 2019, other unallocated items include a $207 million gain resulting from the agreements executed with Capline LLC to contribute our 33 percent undivided interest in the Capline pipeline system in exchange for a 33 percent ownership interest in Capline LLC and a litigation reserve of $22 million.

During the third quarter of 2020, we announced strategic actions to lay a foundation for long-term success, including plans to optimize our assets and structurally lower costs in 2021 and beyond, which included indefinitely idling the Gallup and Martinez refineries and the approval of an involuntary workforce reduction plan. In connection with these strategic actions, we recorded restructuring expenses of $348 million for the three months ended September 30, 2020.

Non-GAAP Financial Measures

Management uses certain financial measures to evaluate our operating performance that are calculated and presented on the basis of methodologies other than in accordance with GAAP. We believe these non-GAAP financial measures are useful to investors and analysts to assess our ongoing financial performance because, when reconciled to their most comparable GAAP financial measures, they provide improved comparability between periods through the exclusion of certain items that we believe are not indicative of our core operating performance and that may obscure our underlying business results and trends. These measures should not be considered a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP, and our calculations thereof may not be comparable to similarly titled measures reported by other companies. The non-GAAP financial measures we use are as follows:

Refining & Marketing Margin

Cash used in dividend payments increased $79 million in the first nine months of 2020 compared to the first nine months of 2019, primarily due to a $0.15 per share increase in our base dividend, partially offset by a reduction of shares resulting from share repurchases in 2019. Our dividend payments were $1.74 per common share in the first nine months of 2020 compared to $1.59 per common share in the first nine months of 2019.

Contributions from noncontrolling interests decreased $95 million in the first nine months of 2020 compared to the first nine months of 2019 primarily due to cash received in 2019 for an increased noncontrolling interest in an MPLX subsidiary.

Capital Resources

MPC, Excluding MPLX

We control MPLX through our ownership of the general partner, however, the creditors of MPLX do not have recourse to MPC’s general credit through guarantees or other financial arrangements. The assets of MPLX can only be used to settle its own obligations and its creditors have no recourse to our assets. Therefore, in the following table, we present the liquidity of MPC, excluding MPLX. MPLX liquidity is discussed in the following section.

Our liquidity, excluding MPLX, totaled ~~$8.44~~$4.47 billion at ~~September 30, 2020~~March 31, 2021 consisting of:


	March 31, 2021
(In millions)	Total Capacity		Outstanding Borrowings		Available Capacity

(b)Availability under our $750 million trade receivables facility is a function of eligible trade receivables, which will be lower in a sustained lower price environment for refined products.

(c)We do not intend to have outstanding commercial paper borrowings in excess of available capacity under bank revolving credit facilities.

(d)Includes cash and cash equivalents classified as assets held for sale of $134 million (see Note 3 to the unaudited consolidated financial statements) and excludes cash and cash equivalents of MPLX of $24 million.

~~Excludes MPLX’s $3.50 billion bank revolving credit facility, which had approximately $3.41 billion available as of September 30, 2020.~~


^(b)	~~Outstanding borrowings include $1 million in letters of credit outstanding under this facility.~~


^(c)	~~Availability under our $750 million trade receivables facility is a function of eligible trade receivables, which will be lower in a sustained lower price environment for refined products.~~


^(d)	Includes cash and cash equivalents classified as assets held for sale of $98 million (see Note 4 to the unaudited consolidated financial statements) and excludes cash and cash equivalents of MPLX of $28 million.

Because of the alternatives available to us, including internally generated cash flow and access to capital markets and a commercial paper program, we believe that our short-term and long-term liquidity is adequate to fund not only our current operations, but also our near-term and long-term funding requirements, including capital spending programs, dividend payments, defined benefit plan contributions, repayment of debt maturities ~~the repurchase of shares of our common stock~~ and other amounts that may ultimately be paid in connection with contingencies. We did not repurchase shares during the three months ended March 31, 2021. The timing and amount of future repurchases will depend upon several factors, including market and business conditions, and such repurchases may be initiated, suspended or discontinued at any time.

Additionally, we have recorded an income tax receivable within other current assets in our balance sheet of approximately $2.1 billion which is expected to be received during the second half of 2021.

We have a commercial paper program that allows us to have a maximum of $2.0 billion in commercial paper outstanding. We do not intend to have outstanding commercial paper borrowings in excess of available capacity under our bank revolving credit facility. ~~As of September 30, 2020,~~At March 31, 2021, we had no$1.72 billion outstanding under the commercial paper ~~borrowings outstanding.~~

~~On October 1, 2020, all of the $475 million outstanding aggregate principal amount of 5.375 percent senior notes due October 2022 were redeemed at a price equal to par using available cash~~program, which matures on ~~hand and liquidity provided through MPC’s credit facilities.~~

~~Table of Contents~~

On September 23, 2020, MPC entered into a 364-day revolving credit agreement with a syndicate of lenders. This revolving credit agreement provides for a $1.0 billion unsecured revolving credit facility that matures in September 2021, and replaces a similar 364-day revolving credit agreement that expired on September 28, 2020.

~~On April 27, 2020, MPC entered into a 364-day revolving credit agreement with a syndicate of lenders providing for a $1.0 billion unsecured revolving credit facility that matures in April 2021.~~

These two credit agreements contain representations and warranties, affirmative and negative covenants and events of default that MPC considers customary for agreements of similar nature and type and that are substantially similar to each other and those containedvarious dates in the ~~credit agreement for MPC’s $5.0 billion bank revolving credit facility.~~

~~On April 27, 2020, MPC closed on the issuance~~second quarter of $2.5 billion in aggregate principal amount of senior notes in a public offering, consisting of $1.25 billion aggregate principal amount of 4.500 percent unsecured senior notes due 2023 and $1.25 billion aggregate principal amount of 4.700 percent unsecured senior notes due 2025. MPC used the net proceeds from this offering to repay certain amounts outstanding under its five-year revolving credit facility.2021.

The MPC credit agreements and our trade receivables facility contain representations and warranties, affirmative and negative covenants and events of default that we consider usual and customary for agreements of these types. The financial covenant included in the MPC credit agreements requires us to maintain, as of the last day of each fiscal quarter, a ratio of Consolidated Net Debt to Total Capitalization (as defined in the MPC credit agreements) of no greater than 0.65 to 1.00. As of ~~September 30, 2020,~~March 31, 2021, we were in compliance with the covenants contained in the MPC bank revolving credit facility and our trade receivables facility, including the financial covenant with a ratio of Consolidated Net Debt to Total Capitalization of ~~0.36~~0.40 to 1.00.

Our intention is to maintain an investment-grade credit profile. As of ~~September 30, 2020,~~April 20, 2021, the credit ratings on our senior unsecured debt are as follows.



Company	Rating Agency	Rating
MPC	Moody’s	Baa2 (negative outlook)
	Standard & Poor’s	BBB (negative outlook)
	Fitch	BBB ~~(negative~~(stable outlook)

The ratings reflect the respective views of the rating agencies. Although it is our intention to maintain a credit profile that supports an investment-grade rating, there is no assurance that these ratings will continue for any given period of time. The ratings may be revised or withdrawn entirely by the rating agencies if, in their respective judgments, circumstances so warrant.

None of the MPC credit agreements or our trade receivables facility contains credit rating triggers that would result in the acceleration of interest, principal or other payments in the event that our credit ratings are downgraded. However, any downgrades of our senior unsecured debt could increase the applicable interest rates, yields and other fees payable under such agreements and may limit our flexibility to obtain financing in the future, including to refinance existing indebtedness. In addition, a downgrade of our senior unsecured debt rating to below investment-grade levels could, under certain circumstances, decrease the amount of trade receivables that are eligible to be sold under our trade receivables facility, impact our ability to purchase crude oil on an unsecured basis and could result in us having to post letters of credit under existing transportation services or other agreements.

See Note 1917 to the unaudited consolidated financial statements for further discussion of our debt.

During the third quarter of 2020, a portion of the net proceeds from the senior notes offering was used to repay the $1.0 billion of outstanding borrowings under the MPLX term loan agreement, to repay the $1.0 billion floating rate senior notes due September 2021 and to redeem all of the $450 million aggregate principal amount of 6.375 percent senior notes due May 2024. On October 15, 2020, a portion of the remaining net proceeds from the senior notes offering was used to redeem all of the $300 million aggregate principal amount of 6.250 percent senior notes due October 2022.

The MPLX credit agreement contains certain representations and warranties, affirmative and restrictive covenants and events of default that we consider to be usual and customary for an agreement of this type. The financial covenant requires MPLX to maintain a ratio of Consolidated Total Debt as of the end of each fiscal quarter to Consolidated EBITDA (both as defined in the MPLX credit agreement) for the prior four fiscal quarters of no greater than 5.0 to 1.0 (or 5.5 to 1.0 during the six-month period following certain acquisitions). Consolidated EBITDA is subject to adjustments for certain acquisitions completed and capital projects undertaken during the relevant period. Other covenants restrict MPLX and/or certain of its subsidiaries from incurring debt, creating liens on assets and entering into transactions with affiliates. As of ~~September 30, 2020,~~March 31, 2021, MPLX was in compliance with the covenants, including the financial covenant with a ratio of Consolidated Total Debt to Consolidated EBITDA of ~~3.9~~3.8 to 1.0.

Our intention is to maintain an investment-grade credit profile for MPLX. As of ~~September 30, 2020,~~April 20, 2021, the credit ratings on MPLX’s senior unsecured debt are as follows.



Company	Rating Agency	Rating
MPLX	Moody’s	Baa2 (negative outlook)
	Standard & Poor’s	BBB (negative outlook)
	Fitch	BBB ~~(negative~~(stable outlook)

The ratings reflect the respective views of the rating agencies. Although it is our intention to maintain a credit profile that supports an investment-grade rating for MPLX, there is no assurance that these ratings will continue for any given period of time. The ratings may be revised or withdrawn entirely by the rating agencies if, in their respective judgments, circumstances so warrant.

The agreements governing MPLX’s debt obligations do not contain credit rating triggers that would result in the acceleration of interest, principal or other payments in the event that MPLX credit ratings are downgraded. However, any downgrades of MPLX senior unsecured debt to below investment grade ratings could increase the applicable interest rates, yields and other fees payable under such agreements. In addition, a downgrade of MPLX senior unsecured debt ratings to below investment-grade levels may limit MPLX’s ability to obtain future financing, including to refinance existing indebtedness.

See Item 8. Financial Statements and Supplementary Data – Note 1917 for further discussion of MPLX’s debt.

Capital Requirements

MPC's capital investment plan for ~~continuing and discontinued operations for 2020 originally totaled~~2021 totals approximately ~~$2.6~~$1.4 billion for capital projects and investments, excluding ~~MPLX,~~ capitalized interest, potential acquisitions and ~~acquisitions.~~MPLX’s capital investment plan. MPC’s capital investment plan includes all of the planned capital spending for Refining & Marketing and Corporate, as well as a portion of the planned capital investments in Midstream and Speedway’s capital spending for the first quarter of 2021, which is now reported separately as discontinued operations. ~~MPLX’s~~The remainder of the planned capital spending for Midstream reflects the capital investment plan for ~~2020 originally totaled approximately $1.75 billion.~~

~~In response~~MPLX, which totals $1.0 billion excluding project reimbursements paid by MPC to ~~the COVID-19 environment, the company announced a consolidated~~MPLX and return of capital spending reduction of $1.35 billion to $3.0 billion for 2020. Remaining capital spend primarily relates to growth projects that are already in progress or spending that supports the safe and reliable operation of our facilities.from MPLX’s joint venture partners. We continuously evaluate our capital investment plan and make changes as conditions warrant.

As of ~~September 30, 2020,~~March 31, 2021, our contractual cash obligations included long-term debt, capital and operating lease obligations, purchase obligations and other long-term liabilities. During the first ~~nine~~three months of ~~2020,~~2021, our long-term debt commitments increased approximately ~~$2.9 billion~~$620 million primarily due to ~~$2.5~~ borrowings under the MPC revolving credit facility and commercial paper program and the MPLX revolving credit facility, partially offset by the repayment of $1.0 billion of MPC senior notes ~~issued~~ and ~~$3.0 billion~~the redemption of ~~MPLX senior notes issued, the proceeds of which were used to repay $1.0 billion of the MPLX term loan and $1.0 billion of MPLX floating rate notes and redeem $450~~$750 million of MPLX senior notes.

There were no other material changes to our contractual cash obligations outside the ordinary course of business since December 31, ~~2019.~~2020.

Off-Balance Sheet Arrangements

Off-balance sheet arrangements comprise those arrangements that may potentially impact our liquidity, capital resources and results of operations, even though such arrangements are not recorded as liabilities under U.S. GAAP. Our off-balance sheet arrangements are limited to indemnities and guarantees that are described below. Although these arrangements serve a variety of our business purposes, we are not dependent on them to maintain our liquidity and capital resources, and we are not aware of any circumstances that are reasonably likely to cause the off-balance sheet arrangements to have a material adverse effect on our liquidity and capital resources.

We have provided various guarantees related to equity method investees. ~~In conjunction with our spinoff from Marathon Oil, we entered into various indemnities and guarantees to Marathon Oil.~~ These arrangements are described in Note 2422 to the unaudited consolidated financial statements.

ENVIRONMENTAL MATTERS AND COMPLIANCE ~~COST~~SCOSTS

We have incurred and may continue to incur substantial capital, operating and maintenance, and remediation expenditures as a result of environmental laws and regulations. If these expenditures, as with all costs, are not ultimately reflected in the prices of our products and services, our operating results will be adversely affected. We believe that substantially all of our competitors must comply with similar environmental laws and regulations. However, the specific impact on each competitor may vary depending on a number of factors, including the age and location of its operating facilities, marketing areas, production processes and whether it is also engaged in the petrochemical business or the marine transportation of crude oil and refined products.

There have been no significant changes to our environmental matters and compliance costs during the ~~nine~~three months ended ~~September 30, 2020.~~March 31, 2021.

CRITICAL ACCOUNTING ESTIMATES

As of ~~September 30, 2020,~~March 31, 2021, there have been no significant changes to our critical accounting estimates since our Annual Report on Form 10-K for the year ended December 31, ~~2019 except as noted below.~~2020.

~~Impairment Assessments of Long-Lived Assets, Intangible Assets, Goodwill and Equity Method Investments~~

Fair value calculated for the purpose of testing our long-lived assets, intangible assets, goodwill and equity method investments for impairment is estimated using the expected present value of future cash flows method and comparative market prices when appropriate. Significant judgment is involved in performing these fair value estimates since the results are based on forecasted financial information prepared using significant assumptions including:


•	~~Future operating performance~~. Our estimates of future operating performance are based on our analysis of various supply and demand factors, which include, among other things, industry-wide capacity, our planned utilization rate, end-user demand, capital expenditures and economic conditions. Such estimates are consistent with those used in our planning and capital investment reviews.

•

~~Future volumes~~. Our estimates of future refinery, pipeline throughput and natural gas and natural gas liquid processing volumes are based on internal forecasts prepared by our Refining & Marketing and Midstream segments operations personnel. Assumptions about the effects of COVID-19 on our future volumes are inherently subjective and contingent upon the duration of the pandemic, which is difficult to forecast.


•	~~Discount rate commensurate with the risks involved.~~ We apply a discount rate to our cash flows based on a variety of factors, including market and economic conditions, operational risk, regulatory risk and political risk. This discount rate is also compared to recent observable market transactions, if possible. A higher discount rate decreases the net present value of cash flows.

~~Table of Contents~~


•	~~Future capital requirements.~~ ~~These are based on authorized spending and internal forecasts.~~

Assumptions about the effects of COVID-19 and the macroeconomic environment are inherently subjective and contingent upon the duration of the pandemic and its impact on the macroeconomic environment, which is difficult to forecast. We base our fair value estimates on projected financial information which we believe to be reasonable. However, actual results may differ from these projections.

The need to test for impairment can be based on several indicators, including a significant reduction in prices of or demand for products produced, a weakened outlook for profitability, a significant reduction in pipeline throughput volumes, a significant reduction in natural gas or natural gas liquids processed, a significant reduction in refining margins, other changes to contracts or changes in the regulatory environment.

Long-lived assets used in operations are assessed for impairment whenever changes in facts and circumstances indicate that the carrying value of the assets may not be recoverable based on the expected undiscounted future cash flow of an asset group. For purposes of impairment evaluation, long-lived assets must be grouped at the lowest level for which independent cash flows can be identified, ~~which generally is the refinery and associated distribution system level for Refining & Marketing segment assets, and the plant level or pipeline system level for Midstream segment assets~~. If the sum of the undiscounted estimated pretax cash flows is less than the carrying value of an asset group, fair value is calculated, and the carrying value is written down to the calculated fair value.

During the first quarter of 2020, we identified long-lived asset impairment triggers relating to all of our refinery asset groups within the Refining & Marketing segment as a result of decreases to the Refining & Marketing segment expected future cash flows. The cash flows associated with these assets were significantly impacted by the effects of COVID-19 and commodity price declines. We assessed each refinery asset group for impairment by comparing the undiscounted estimated pretax cash flows to the carrying value of each asset group. Of the 16 refinery asset groups, only the Gallup refinery’s carrying value exceeded its undiscounted estimated pretax cash flows. It was determined that the fair value of the Gallup refinery’s property, plant and equipment was less than the carrying value. As a result, we recorded a charge of $142 million in the first quarter of 2020 to impairment expense on the consolidated statements of income. The fair value measurements for the Gallup refinery assets represent Level 3 measurements.

The determination of undiscounted estimated pretax cash flows for our long-lived asset impairment tests utilized significant assumptions including management’s best estimates of the expected future cash flows, allocation of certain Refining & Marketing segment cash flows to the individual refineries, the estimated useful lives of the asset groups, and the salvage values of the refineries. The determinations of expected future cash flows and the salvage values of refineries require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of our impairment analysis will prove to be an accurate prediction of the future. Should our assumptions significantly change in future periods, it is possible we may determine the carrying values of additional refinery asset groups exceed the undiscounted estimated pretax cash flows of their refinery asset groups, which would result in future impairment charges.

During the first quarter of 2020, MPLX identified an impairment trigger relating to asset groups within its Western Gathering & Processing (“G&P”) reporting unit as a result of significant changes to expected future cash flows for these asset groups resulting from the effects of COVID-19. The cash flows associated with these assets were significantly impacted by volume declines reflecting decreased forecasted producer customer production as a result of lower commodity prices. MPLX assessed each asset group within the Western G&P reporting unit for impairment. It was determined that the fair value of the East Texas G&P asset group’s underlying assets was less than the carrying value. As a result, MPLX recorded impairment charges totaling $350 million related to its property, plant and equipment and intangibles, which are included in impairment expense on our consolidated statements of income. Fair value of MPLX’s PP&E was determined using a combination of an income and cost approach. The income approach utilized significant assumptions including management’s best estimates of the expected future cash flows and the estimated useful life of the asset group. The cost approach utilized assumptions for the current replacement costs of similar assets adjusted for estimated depreciation and deterioration of the existing equipment. The fair value of the intangibles was determined based on applying the multi-period excess earnings method, which is an income approach. Key assumptions included management’s best estimates of the expected future cash flows from existing customers, customer attrition rates and the discount rate. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the impairment analysis will prove to be an accurate prediction of the future. The fair value measurements for the asset group fair values represent Level 3 measurements.

Unlike long-lived assets, goodwill is subject to annual, or more frequent if necessary, impairment testing at the reporting unit level. A goodwill impairment loss is measured as the amount by which a reporting unit's carrying value exceeds its fair value, without exceeding the recorded amount of goodwill.

The “Business Update” under Recent Developments in the Corporate Overview section describes the effects that the outbreak of COVID-19, its development into a pandemic and the effect the decline in commodity prices during the first quarter of 2020 have had on our business. Due to these developments, we performed impairment assessments during the first quarter of 2020 as discussed further below.

Prior to performing our goodwill impairment assessment as of March 31, 2020, we had goodwill totaling approximately $20 billion associated with eight of our 10 reporting units. As part of this assessment, we recorded goodwill impairment expenses of $7.33 billion in the first quarter of 2020 related to our Refining & Marketing and MPLX’s Eastern G&P reporting units. The Refining & Marketing and Eastern G&P reporting units recorded goodwill impairment charges of $5.52 billion and $1.81 billion, respectively, which fully impaired both reporting units’ historical goodwill balances. These goodwill impairment expenses are primarily driven by the effects of COVID-19, the decline in commodity prices and the slowing of drilling activity which has reduced production growth forecasts from MPLX’s producer customers. For the remaining six reporting units with goodwill, we determined that no significant adjustments to the carrying value of goodwill were necessary. The impairment assessment performed as of March 31, 2020 resulted in the fair value of the reporting units exceeding their carrying value by percentages ranging from approximately 8.5 percent to 270.0 percent. MPLX’s Crude Gathering reporting unit had goodwill totaling $1.1 billion at March 31, 2020 and MPLX’s fair value estimate for this reporting unit exceeded the reporting unit carrying value by 8.5 percent. The operations that make up this reporting unit were acquired by MPLX when it acquired ANDX. We accounted for the October 1, 2018 acquisition of Andeavor (through which we acquired control of ANDX), using the acquisition method of accounting, which required Andeavor assets and liabilities to be recorded at the acquisition date fair value. As such, given the short amount of time from when fair value was established to the date of the impairment test, the amount by which the fair value exceeded the carrying value within this reporting unit is not unexpected. An increase of one percentage point to the discount rate used to estimate the fair value of this reporting unit would not have resulted in goodwill impairment as of March 31, 2020. No other reporting units had fair values exceeding carrying values of less than 20 percent.

Significant assumptions used to estimate the reporting units’ fair value included estimates of future cash flows and market information for comparable assets. If estimates for future cash flows, which are impacted by future margins on products produced or sold, future volumes, and capital requirements, were to decline, the overall reporting units’ fair values would decrease, resulting in potential goodwill impairment charges. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the impairment tests will prove to be an accurate prediction of the future.

Equity method investments are assessed for impairment whenever factors indicate an other than temporary loss in value. Factors providing evidence of such a loss include the fair value of an investment that is less than its carrying value, absence of an ability to recover the carrying value or the investee’s inability to generate income sufficient to justify our carrying value. During the first quarter of 2020, we recorded $1.32 billion of equity method investment impairment charges to income from equity method investments in the consolidated statements of income. The impairment charges primarily related to MPLX recording an other than temporary impairment totaling $1.26 billion, of which $1.25 billion related to MarkWest Utica EMG, L.L.C and its investment in Ohio Gathering Company, L.L.C. The fair value of the investments was determined based upon

~~Table of Contents~~

applying the discounted cash flow method, which is an income approach. The discounted cash flow fair value estimate is based on known or knowable information at the interim measurement date. The significant assumptions that were used to develop the estimate of the fair value under the discounted cash flow method include management’s best estimates of the expected future cash flows, including prices and volumes, the weighted average cost of capital and the long-term growth rate. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As such, the fair value of these equity method investments represents a Level 3 measurement. As a result, there can be no assurance that the estimates and assumptions made for purposes of the impairment test will prove to be an accurate prediction of the future. The impairment was recorded through “Income from equity method investments.” The impairments were largely due to a reduction in forecasted volumes gathered and processed by the systems operated by the joint ventures. At September 30, 2020 we had $5.46 billion of equity method investments recorded on the Consolidated Balance Sheets.

An estimate of the sensitivity to net income resulting from impairment calculations is not practicable, given the numerous assumptions (e.g., pricing, volumes and discount rates) that can materially affect our estimates. That is, unfavorable adjustments to some of the above listed assumptions may be offset by favorable adjustments in other assumptions.

We remain at risk for possible changes in the market value of commodity derivative instruments; however, such risk should be mitigated by price changes in the underlying physical commodity. Effects of these offsets are not reflected in the above sensitivity analysis.

We evaluate our portfolio of commodity derivative instruments on an ongoing basis and add or revise strategies in anticipation of changes in market conditions and in risk profiles. Changes to the portfolio after ~~September 30, 2020~~March 31, 2021 would cause future IFO effects to differ from those presented above.

Sensitivity analysis of the effect of a hypothetical 100-basis-point change in interest rates on long-term debt, including the portion classified as current and excluding finance leases, as of ~~September 30, 2020~~March 31, 2021 is provided in the following table. Fair value of cash and cash equivalents, receivables, accounts payable and accrued interest approximate carrying value and are relatively insensitive to changes in interest rates due to the short-term maturity of the instruments. Accordingly, these instruments are excluded from the table.
