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. 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. 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 in our consolidated statements of income for all periods presented and its assets and liabilities have been 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 4 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.


•	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.

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. The results of operations for the three and nine months ended September 30, 2020 are not necessarily indicative of the results to be expected for the full year.

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 during the first nine months of 2020, which also did not have a material impact to our financial statements or financial statement disclosures:



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 quarter of 2021, subject to customary closing conditions and 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 presented in our consolidated balance sheets as assets and liabilities held for sale. Additionally, 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. 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 a 15-year fuel supply agreement, 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, 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.

5. 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 we owned approximately 62 percent of the outstanding MPLX common units.

Redemption of business from MPLX

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 held by WRSW. The transaction effects the transfer to MPC of 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 MPLX common units (the “Redeemed Units”) held by WRSW. The number of Redeemed Units was calculated by dividing WRW’s aggregate valuation of $340 million by the simple average of the volume weighted average New York Stock Exchange prices of an MPLX common unit for the ten trading days ending at market close on July 27, 2020. The transaction resulted in a minor decrease in MPC’s ownership interest in MPLX.

Table of Contents

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 right to receive 1.135 MPLX common units. ANDX common units held by MPC were converted into the right to receive 1.0328 MPLX common units. Additionally, as a result 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 arrears on the 15th day of February, May, August and November of each year, 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.

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. 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 overall deterioration in the economy and the environment in which we operate, the related changes to our expected future cash flows, as well as a sustained decrease in share price were considered triggering events requiring various impairment assessments of the carrying values of our assets, which resulted in the majority of the impairment charges for the nine months ended September 30, 2020, as discussed below.

Table of Contents

The table below provides information related to the impairments recognized during the three and nine months ended September 30, 2020 and the location of these impairments within the consolidated statements of income.



		Three Months Ended September 30,		Nine Months End September 30,
(In millions)	Income Statement Line	2020		2020
Goodwill	Impairment expense	$	64	$	7,394
Equity method investments	Income (loss) from equity method investments	—		1,315
Long-lived assets	Impairment expense	369		886
Total impairments		$	433	$	9,595

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 goodwill impairment within the Refining & Marketing segment was primarily driven by the effects of COVID-19 and the decline in commodity prices. The impairment within the Midstream segment was primarily driven by additional information related to the slowing of drilling activity, which has 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 goodwill impairment analysis were determined based on applying both a discounted cash flow 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.

The changes in carrying amount of goodwill were as follows:



(In millions)	Refining & Marketing			Midstream			Total
Balance at January 1, 2020	$	6,133		$	9,517		$	15,650

^(a)	Includes goodwill of $64 million transferred from our Midstream segment to our Refining & Marketing segment in connection with the transfer to MPC of the MPLX wholesale distribution business as described in Note 5.


^(b)	As described in Notes 1 and 11, the Refining & Marketing reportable segment includes the direct dealer business, which was a reporting unit in our former Retail segment and now is a reporting unit within our Refining & Marketing segment with $561 million of goodwill.

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. 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 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 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.

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 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. 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 of property, plant and equipment 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 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 asset group fair values represent Level 3 measurements.

7. 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 24 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.

Sales to related parties, which are included in sales and other operating revenues, consist primarily of refined product sales to certain of our equity affiliates.

Purchases from related parties are included in cost of revenues. We obtain utilities, transportation services and purchase ethanol from certain of our equity affiliates.

9. EARNINGS 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.

10. EQUITY

As of September 30, 2020, we had $2.96 billion of remaining share repurchase authorizations from our board of directors. We may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block transactions, tender offers, accelerated share repurchases or open market solicitations for shares, some of which may be effected through Rule 10b5-1 plans. The timing and amount of future repurchases, if any, will depend upon several factors, including market and business conditions, and such repurchases may be initiated, suspended or discontinued at any time.

Total share repurchases were as follows for the respective periods:

11. 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 two 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 3,900 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.

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) are not allocated to the reportable segments.

13. 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 for the three months ended September 30, 2020 and 2019, respectively, and 16 percent and 20 percent for the nine months ended September 30, 2020 and 2019, respectively. The effective tax benefit rate for the three months ended September 30, 2020 was higher 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 effective tax rate for the nine months ended September 30, 2019 was less than the U.S. statutory rate 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.

Table of Contents

A reconciliation of the continuing operations tax provision (benefit) in dollars as determined using the federal statutory income tax rate applied to income (loss) before income taxes to the (benefit) provision for income taxes is shown in the table below.

During the first quarter of 2019, MPC’s provision for income taxes was increased $36 million for an out of period adjustment to correct the tax effects recorded in 2018 related to the Andeavor acquisition. The impact of the adjustment was not material to any previous period.

We are continuously undergoing examination of our income tax returns, which have been completed through the 2005 tax year for state returns and the 2010 tax year for our U.S. federal return. As of September 30, 2020, we had $20 million of unrecognized tax benefits.

Pursuant to our tax sharing agreement with Marathon Oil, the unrecognized tax benefits related to pre-spinoff operations for which Marathon Oil was the taxpayer remain the responsibility of Marathon Oil and we have indemnified Marathon Oil accordingly. See Note 24 for indemnification information.

14. INVENTORIES

Crude oil	$	2,481		$	3,472
Refined products	5,198			5,359
Materials and supplies	909			973
Inventories before LCM inventory valuation reserve	8,588			9,804
LCM inventory valuation reserve	(1,185		)	—
Total	$	7,403		$	9,804

Inventories are carried at the lower of cost or market value. Costs of crude oil and refined products are aggregated on a consolidated basis for purposes of assessing whether the LIFO cost basis of these inventories may have to be written down to market values. At September 30, 2020, market values for these inventories were lower than their LIFO cost basis, resulting in a reserve. 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.

The cost of inventories of crude oil and refined products is determined primarily under the LIFO method. During the three and nine month periods ended September 30, 2020, we recorded a $256 million charge 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 the charge to cost of revenues.

15. EQUITY METHOD INVESTMENTS

During the three months ended March 31, 2019, we executed agreements 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. In connection with our execution of these agreements, Capline LLC initiated a binding open season for southbound service from Patoka, Illinois to St. James, Louisiana or Liberty, Mississippi with an additional origination point at Cushing, Oklahoma. Service from Cushing, Oklahoma is part of a joint tariff with Diamond pipeline.

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.

17. FAIR VALUE MEASUREMENTS

Fair Values—Recurring

The following tables present assets and liabilities accounted for at fair value on a recurring basis as of September 30, 2020 and December 31, 2019 by fair value hierarchy level. We have elected to offset the fair value amounts recognized for multiple derivative contracts executed with the same counterparty, including any related cash collateral as shown below; however, fair value amounts by hierarchy level are presented on a gross basis in the following tables.

^(a)	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 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 used significant unobservable inputs including: (1) NGL prices interpolated and extrapolated due to inactive markets ranging from $0.46 to $0.97 per gallon with a weighted average of $0.58 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 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 of renewal would result in an increase in the fair value of the related embedded derivative liability.

The following is a reconciliation of the beginning and ending balances recorded for net liabilities classified as Level 3 in the fair value hierarchy.

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 billion and $33.3 billion at September 30, 2020, respectively, and approximately $28.3 billion and $30.1 billion at December 31, 2019, respectively. These carrying and fair values of our debt exclude the unamortized issuance costs which are netted against our total debt.

18. DERIVATIVES

For further information regarding the fair value measurement of derivative instruments, including any effect of master netting agreements or collateral, see Note 17. 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.

The following table presents the fair value of derivative instruments as of September 30, 2020 and December 31, 2019 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.

MPC 364-Day Bank Revolving Credit Facilities

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.

MPC is also party to an April 27, 2020 364-day revolving credit agreement that provides 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 contained in the credit agreement for MPC’s $5.0 billion bank revolving credit facility.

MPC Senior Notes

On April 27, 2020, we closed on the issuance 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 May 2023 and $1.25 billion aggregate principal amount of 4.700 percent unsecured senior notes due May 2025. Interest is payable semi-annually in arrears. MPC used the net proceeds from this offering to repay certain amounts outstanding under its five-year revolving credit facility.

On September 25, 2020, we announced that all of the $650 million outstanding aggregate principal amount of 3.400 percent senior notes due December 2020 will be redeemed on November 15, 2020, at a price equal to par, plus accrued and unpaid interest to, but not including, such date.

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.

MPLX Senior Notes

On August 18, 2020, MPLX issued $3.0 billion aggregate principal amount of senior notes in a public offering, consisting of $1.5 billion aggregate principal amount of 1.750 percent senior notes due March 2026 and $1.5 billion aggregate principal amount of 2.650 percent senior notes due August 2030. Interest is payable semi-annually in arrears.

During the third quarter of 2020, a portion of the net proceeds from the senior notes offering was used to repay $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 MPLX’s 6.250 percent senior notes due October 2022.

24. 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.

At September 30, 2020 and December 31, 2019, accrued liabilities for remediation totaled $388 million and $396 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 $7 million and $9 million at September 30, 2020 and December 31, 2019, respectively.

Governmental and other entities in California, Delaware, Hawaii, Maryland, New York, South Carolina and Rhode Island have filed lawsuits against coal, gas, oil and petroleum 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. Similar lawsuits may be filed in other jurisdictions. At this early stage, the ultimate outcome of these matters remains 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 to 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, 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 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.

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.

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 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. In the D.D.C., briefing is ongoing 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. 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, 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, our maximum potential undiscounted payments under this agreement for debt principal totaled $119 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, our maximum potential undiscounted payments under this arrangement was $115 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 million as of September 30, 2020, 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

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, our contractual commitments to acquire property, plant and equipment and advance funds to equity method investees totaled $447 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

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.

•


•	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

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:

•


•	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.

Business Update

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. As a result, there has also been a decline in the demand for the refined petroleum products that we manufacture and sell.

The decrease in the demand for refined petroleum products coupled with a decline in the price of crude oil has resulted in a significant decrease in the price and volume of the refined petroleum products we produce and sell and had a negative impact on working capital during the first nine months of 2020.

In addition, a decline 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 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. 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 in the year we took action to address our liquidity as outlined below:


•	Share repurchases have temporarily been suspended. The timing and amount 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 the commodity price and demand downturn.


•	On April 27, 2020, we closed on the issuance of $2.5 billion of senior notes. Proceeds 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.

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 MPC’s board of directors unanimously decided to maintain MPC’s current midstream structure, with MPC remaining, through a wholly owned subsidiary, the general partner of MPLX. This decision concluded a comprehensive evaluation, led by a special committee of the board, that included extensive input from multiple external advisors and significant feedback from investors.

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) attributable to MPC was $(886) 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) per diluted share, in the first nine months of 2020 compared to $2.19 billion, or $3.28 per diluted share, in the first nine 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. These changes 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 increased income from discontinued operations, which relates to the Speedway business, in the third 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 with a market value of $10.19 billion based on the September 30, 2020 closing price of $15.74 per common unit. On October 27, 2020, MPLX declared a quarterly cash distribution of $0.6875 per common unit payable on November 13, 2020. As a result, MPLX will make distributions totaling $715 million to its common unitholders. MPC’s portion of these distributions is approximately $445 million.

We received limited partner distributions of $1.35 billion from MPLX in the nine months ended September 30, 2020 and $1.39 billion from MPLX and ANDX combined in the nine months ended September 30, 2019. The decrease in distributions from 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 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 of MPLX common units held by WRSW. The transaction effects the transfer 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.

See Note 5 to the unaudited consolidated financial statements for additional information on MPLX.

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 on hand and liquidity provided through MPC’s credit facilities.

On September 25, 2020, we announced that all of the $650 million outstanding aggregate principal amount of 3.400 percent senior notes due December 2020 will be redeemed on November 15, 2020, using available cash on hand and liquidity provided through MPC’s credit facilities, at a price equal to par, plus accrued and unpaid interest to, but not including, such date.

MPLX’s liquidity totaled $4.93 billion at September 30, 2020. As of September 30, 2020, MPLX had cash and cash equivalents of $28 million, $3.41 billion available under its $3.5 billion revolving credit agreement and $1.5 billion available through its intercompany loan agreement with MPC.

OVERVIEW OF SEGMENTS

Refining & Marketing

Refining & Marketing segment income from operations depends largely on our Refining & Marketing margin, refining operating costs, distribution costs, refining planned turnaround 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 crude producing two barrels of USGC CBOB gasoline and one barrel of USGC ULSD;


•	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.

The following table provides sensitivities showing an estimated change in annual net income due to potential changes in market conditions.



(In millions, after-tax)
Blended crack spread sensitivity^(a)(per $1.00/barrel change)	$	910
Sour differential sensitivity^(b) (per $1.00/barrel change)	420
Sweet differential sensitivity^(c) (per $1.00/barrel change)	420
Natural gas price sensitivity^(d) (per $1.00/MMBtu)	325


^(a)	Crack spread based on 38 percent LLS, 38 percent WTI and 24 percent ANS with Gulf Coast, Mid-Continent and West Coast product pricing, respectively, and assumes all other differentials and pricing relationships remain unchanged.


^(b)	Sour crude oil basket consists of the following crudes: ANS, Argus Sour Crude Index, Maya and Western Canadian Select. We expect approximately 50 percent of the crude processed at our refineries in 2020 will be sour crude.


^(c)	Sweet crude oil basket consists of the following crudes: Bakken, Brent, LLS, WTI-Cushing and WTI-Midland. We expect approximately 50 percent of the crude processed at our refineries in 2020 will be sweet crude.


^(d)	This is consumption-based exposure for our Refining & Marketing segment and does not include the sales exposure for our Midstream segment.

Table of Contents

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.

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, as discussed below, which are based on committed volumes 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 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 Quarter 2020 Compared to Third Quarter 2019

Net income (loss) attributable to MPC decreased $1.98 billion in the third quarter of 2020 compared to the third quarter of 2019 largely due to a decrease in refined product sales volumes, prices and margin, 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. This was partially offset by a charge of $256 million 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 the LIFO liquidation charge;


•	long-lived asset impairment expenses of $433 million primarily related to the repositioning of the Martinez refinery;


•	decreased selling, general and administrative expenses of $88 million mainly due to decreases in salaries and employee-related expenses, contract services expenses, credit card processing fees for brand customers, and transaction-related costs, partially offset by increases in employee benefit costs and other expenses;


•	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 million largely due to increased MPC borrowings and decreased capitalized interest and interest income.

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. The combined federal, state and foreign income tax rate was 31 percent (tax benefit rate) and 19 percent for the three months ended September 30, 2020 and 2019, respectively. The effective tax benefit rate for the three months ended September 30, 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.

Table of Contents

Costs and expenses decreased $16.34 billion primarily due to:

•

decreased cost of revenues of $26.11 billion primarily due to reduced travel and business operations associated with the COVID-19 pandemic, partially offset by increased cost of revenues of $256 million 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 the LIFO liquidation charge;


•	an LCM charge of $1.19 billion primarily driven by the effects of COVID-19 and the decline in commodity prices;


•	impairment expense of $8.28 billion recorded for goodwill and long-lived assets of $7.39 billion and $886 million, respectively, primarily driven by the effects of COVID-19 and the decline in commodity prices. 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. Additionally, our effective tax rate is generally benefited by our noncontrolling interest in MPLX, but this benefit was lower for the nine months ended September 30, 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.

Net income attributable to noncontrolling interests decreased $1.24 billion primarily due to MPLX’s net loss primarily resulting from impairment expense recognized during the first nine months of 2020.

Third Quarter 2020 Compared to Third Quarter 2019

Income from discontinued operations, net of tax, increased $117 million. Quarterly results reflected higher fuel and merchandise margins, 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 Pilot Travel Centers LLC (“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 $36 million and $94 million, for third quarter of 2020 and 2019, respectively.

The Speedway fuel margin increased to 30.25 cents per gallon in the third quarter of 2020, from 26.04 cents per gallon in the third quarter of 2019.

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.

The Speedway fuel margin increased to 36.40 cents per gallon in the first nine months of 2020 compared with 23.79 cents per gallon in the first nine months of 2019.

Third Quarter 2020 Compared to Third Quarter 2019

Refining & Marketing segment revenues decreased $10.13 billion primarily due to 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.

Net refinery throughputs decreased 620 mbpd during the third quarter of 2020, 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 primarily due to lower blended crack spreads.

Refining & Marketing margin, excluding LIFO liquidation charge, was $8.28 per barrel for the third quarter of 2020 compared to $15.11 per barrel for the third quarter of 2019. 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 on Refining & Marketing margin for the third quarter of 2020 compared to the third quarter 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, 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 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 $200 million on Refining & Marketing segment income in the third quarter of 2020 compared to the third quarter of 2019.

For the three months ended September 30, 2020, refining operating costs, excluding depreciation and amortization, decreased $314 million compared to the three months ended September 30, 2019 as we took actions to reduce costs in response to the

Table of Contents

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 of 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, excluding LIFO liquidation charge, was $9.46 per barrel for the first nine months of 2020 compared to $14.17 per barrel for the first nine months of 2019. 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 costs of $138 million. Net refinery throughput was 524 mbpd lower as compared to the nine months ended September 30, 2019. On a per barrel basis, refining operating costs and distribution costs, excluding depreciation and amortization, increased $0.40 and $0.86, respectively, mainly due to lower throughput partially offset by a decrease in costs. Distribution costs, excluding depreciation and amortization, include fees paid to MPLX of $2.59 billion and $2.38 billion for the for the first nine months of 2020 and 2019, respectively. Refining planned turnaround costs increased $0.33 per barrel due to the timing of turnaround activity and a decrease in throughput. Depreciation and amortization per barrel increased by $0.39 primarily due to a decrease in throughput and increased costs.

Third Quarter 2020 Compared to Third Quarter 2019

Midstream segment revenue decreased $17 million primarily due to decreased demand for the products that we produce and transport due to the current macro-economic conditions in addition to lower natural gas prices.

Midstream segment income from operations increased $41 million mainly due to contributions from organic growth projects and reduced operating expenses. Midstream segment income from operations also benefited from stable, fee based earnings in the current business environment.

^(a)	Corporate costs consist primarily of MPC’s corporate administrative expenses and costs related to certain non-operating assets, except for corporate overhead expenses attributable to MPLX, which are included in the Midstream segment.

^(b)

2020 includes costs incurred in connection with the Midstream strategic review. Costs incurred in 2020 in connection with the Speedway separation are included in discontinued operations. 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 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

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 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 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 of 2020, we recorded impairment charges of approximately $9.60 billion, which includes $8.28 billion related to goodwill and long-lived assets and $1.32 billion related to equity method investments, and an LCM charge of $1.19 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:

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

Our consolidated cash and cash equivalents balance for continuing operations was approximately $618 million at September 30, 2020 compared to $1.39 billion at December 31, 2019. Cash and cash equivalents for discontinued operations was $98 million at September 30, 2020 compared to $134 million at December 31, 2019. Net cash provided by (used in) operating activities, investing activities and financing activities are presented in the following table.

Total increase (decrease) in cash	$	(811	)	$	(197	)

Net cash provided by operating activities decreased $5.94 billion in the first nine months of 2020 compared to the first nine months of 2019, primarily due to a decrease in operating results and an unfavorable change in working capital of $1.18 billion

Table of Contents

mainly due to a decrease in accounts payable. These changes were partially offset by an increase in cash provided by discontinued operations of $156 million which reflect the results of the Speedway business. Changes in working capital exclude changes in short-term debt.

Changes in working capital, excluding changes in short-term debt, were a net $490 million use of cash in the first nine months of 2020 compared to a net $687 million source of cash in the first nine months of 2019.

For the first nine months of 2020, changes in working capital, excluding the LCM reserve and changes in short-term debt, were a net $490 million use of cash primarily due to the effects of decreasing energy commodity prices and volumes at the end of the period on working capital. Accounts payable decreased primarily due to decreases in crude prices and volumes. Current receivables decreased primarily due to lower crude prices and lower refined product prices and volumes. Excluding the LCM reserve, inventories decreased primarily due to a decrease in crude and refined products inventories.

For the first nine months of 2019, changes in working capital, excluding changes in short-term debt, were a net $687 million source of cash primarily due to the effects of increasing energy commodity prices at the end of the period on working capital. Current receivables increased primarily due to higher refined product and crude prices and higher crude sales volumes. Accounts payable increased primarily due to increases in crude prices and crude volumes. Inventories decreased due to decreases in refined product and crude inventories, partially offset by an increase in materials and supplies inventory.

Net cash used in investing activities decreased $1.75 billion in the first nine months of 2020 compared to the first nine months of 2019, primarily due to the following:


•	a decrease in additions to property, plant and equipment of $1.13 billion primarily due to decreased capital expenditures in the first nine months of 2020 in our Midstream and Refining & Marketing segments;


•	a decrease in net investments of $403 million largely due to investments in the first nine months of 2019 in connection with the construction of the Gray Oak Pipeline, which began initial start-up in the fourth quarter of 2019; and


•	a decrease in cash used in investing activities related to discontinued operations of $76 million primarily due to decreased capital expenditures in the first nine months of 2020 for Speedway.

The consolidated statements of cash flows exclude changes to the consolidated balance sheets that did not affect cash. A reconciliation of additions to property, plant and equipment per the consolidated statements of cash flows to reported total capital expenditures and investments follows.

•

Long-term debt borrowings and repayments were a net $3.02 billion source of cash in the first nine months of 2020 compared to a net $1.20 billion source of cash in the first nine months of 2019. During the first nine months of 2020, MPC issued $2.5 billion of senior notes, borrowed and repaid $3.5 billion under its revolving credit facility and borrowed and repaid $1.23 billion under its trade receivables facility. MPLX issued $3.0 billion of senior notes, which were used to repay $1.0 billion of outstanding borrowings under its term loan, $1.0 billion of floating rate senior notes and to redeem $450 million of senior notes, and had net borrowings of $95 million under its revolving credit facility. During the first nine months of 2019, MPLX issued $2.0 billion of floating rate senior notes, the proceeds of which were used to repay various outstanding MPLX borrowings, and had net borrowings of $500 million under its term loan.


•	Cash used in common stock repurchases decreased $1.89 billion in the first nine months of 2020 compared to the first nine months of 2019. There were no share repurchases in the first nine months of 2020 compared to $1.89 billion in the first nine months of 2019. See Note 10 to the unaudited consolidated financial statements for further discussion of share repurchases.

Table of Contents

•

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.

Derivative Instruments

See Item 3. Quantitative and Qualitative Disclosures about Market Risk for a discussion of derivative instruments and associated market risk.

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 billion at September 30, 2020 consisting of:



	September 30, 2020
(In millions)	Total Capacity		Outstanding Borrowings		Available Capacity
Bank revolving credit facility^(a)(b)	$	5,000	$	1	$	4,999

Total liquidity					$	8,437


^(a)	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 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, we had no commercial paper borrowings outstanding.

On September 25, 2020, we announced that all of the $650 million outstanding aggregate principal amount of 3.400 percent senior notes due December 2020 will be redeemed on November 15, 2020, using available cash on hand and liquidity provided through MPC’s credit facilities, at a price equal to par, plus accrued and unpaid interest to, but not including, such date.

Table of Contents

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.

On April 27, 2020, MPC closed on the issuance 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.

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, 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 to 1.00.

Our intention is to maintain an investment-grade credit profile. As of September 30, 2020, 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 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 19 to the unaudited consolidated financial statements for further discussion of our debt.

MPLX

MPLX’s liquidity totaled $4.93 billion at September 30, 2020 consisting of:



	September 30, 2020
(In millions)	Total Capacity		Outstanding Borrowings		Available Capacity
MPLX LP - bank revolving credit facility	$	3,500	$	95	$	3,405

Total liquidity					$	4,933

Table of Contents

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, MPLX was in compliance with the covenants, including the financial covenant with a ratio of Consolidated Total Debt to Consolidated EBITDA of 3.9 to 1.0.

Our intention is to maintain an investment-grade credit profile for MPLX. As of September 30, 2020, 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 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 19 for further discussion of MPLX’s debt.

Capital Requirements

Capital Investment Plan

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

In response to the COVID-19 environment, the company announced a consolidated 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. We continuously evaluate our capital investment plan and make changes as conditions warrant.

Capital expenditures and investments in affiliates during the nine months ended September 30, 2020 were primarily for Midstream and Refining & Marketing segment projects.

Other Capital Requirements

During the nine months ended September 30, 2020, we contributed $3 million to our funded pension plans. We may choose to make additional contributions to our pension plans.

On October 28, 2020, our board of directors approved a dividend of $0.58 per share on common stock. The dividend is payable December 10, 2020, to shareholders of record as of the close of business on November 18, 2020.

We have $1.0 billion of 5.125 percent senior notes due in March 2021.

We may, from time to time, repurchase our senior notes in the open market, in tender offers, in privately-negotiated transactions or otherwise in such volumes, at such prices and upon such other terms as we deem appropriate.

Share Repurchases

During the nine months ended September 30, 2020, share repurchases were temporarily suspended, which has helped preserve our liquidity during the COVID-19 pandemic. The timing and amount of future repurchases, if any, will depend upon several factors, including market and business conditions, and such repurchases may be initiated, suspended or discontinued at any time. Since January 1, 2012, our board of directors has approved $18.0 billion in total share repurchase authorizations and we have repurchased a total of $15.05 billion of our common stock, leaving $2.96 billion available for repurchases at September 30, 2020. The table below summarizes our total share repurchases for the nine months ended September 30, 2020 and 2019. See Note 10 to the unaudited consolidated financial statements for further discussion of the share repurchase plans.

Contractual Cash Obligations

As of September 30, 2020, our contractual cash obligations included long-term debt, capital and operating lease obligations, purchase obligations and other long-term liabilities. During the first nine months of 2020, our long-term debt commitments increased approximately $2.9 billion primarily due to $2.5 billion of MPC senior notes issued and $3.0 billion 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 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.

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 24 to the unaudited consolidated financial statements.

ENVIRONMENTAL MATTERS AND COMPLIANCE COSTS

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 months ended September 30, 2020.

CRITICAL ACCOUNTING ESTIMATES

As of September 30, 2020, 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.

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.

ACCOUNTING STANDARDS NOT YET ADOPTED

As discussed in Note 2 to the unaudited consolidated financial statements, certain new financial accounting pronouncements will be effective for our financial statements in the future.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

For a detailed discussion of our risk management strategies and our derivative instruments, see Item 7A. Quantitative and Qualitative Disclosures about Market Risk in our Annual Report on Form 10-K for the year ended December 31, 2019.

See Notes 17 and 18 to the unaudited consolidated financial statements for more information about the fair value measurement of our derivatives, as well as the amounts recorded in our consolidated balance sheets and statements of income. We do not designate any of our commodity derivative instruments as hedges for accounting purposes.

The following table includes the composition of net gains and losses on our commodity derivative positions as of September 30, 2020 and 2019, respectively.



	Nine Months Ended September 30,
(In millions)	2020		2019
Realized gain on settled derivative positions	$	33	$	54
Unrealized gain (loss) on open net derivative positions	47		(87		)
Net gain (loss)	$	80	$	(33	)

See Note 18 to the unaudited consolidated financial statements for additional information on our open derivative positions at September 30, 2020.

Sensitivity analysis of the effects on income from operations (“IFO”) of hypothetical 10 percent and 25 percent increases and decreases in commodity prices for open commodity derivative instruments as of September 30, 2020 is provided in the following table.



	Change in IFO from a Hypothetical Price Increase of						Change in IFO from a Hypothetical Price Decrease of
(In millions)	10%			25%			10%			25%
As of September 30, 2020
Crude	$	3		$	8		$	(3	)	$	(8	)
Refined products	35			87			(35		)	(87		)
Blending products	(13		)	(32		)	13			32
Embedded derivatives	(6		)	(15		)	6			15

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 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 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.

Table of Contents



(In millions)	Fair Value as of September 30, 2020^(a)		Change in Fair Value^(b)		Change in Net Income for the Nine Months Ended September 30, 2020^(c)
Long-term debt
Fixed-rate	$	32,535	$	2,633	n/a
Variable-rate	1,095		n/a		27


^(a)	Fair value was based on market prices, where available, or current borrowing rates for financings with similar terms and maturities.


^(b)	Assumes a 100-basis-point decrease in the weighted average yield-to-maturity at September 30, 2020.


^(c)	Assumes a 100-basis-point change in interest rates. The change to net income was based on the weighted average balance of debt outstanding for the nine months ended September 30, 2020.

At September 30, 2020, our portfolio of long-term debt was comprised of fixed-rate instruments and variable-rate borrowings. The fair value of our fixed-rate debt is relatively sensitive to interest rate fluctuations. Our sensitivity to interest rate declines and corresponding increases in the fair value of our debt portfolio unfavorably affects our results of operations and cash flows only when we elect to repurchase or otherwise retire fixed-rate debt at prices above carrying value. Interest rate fluctuations generally do not impact the fair value of borrowings under our variable-rate debt, but may affect our results of operations and cash flows.

See Note 17 to the unaudited consolidated financial statements for additional information on the fair value of our debt.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) under the Securities Exchange Act of 1934, as amended) was carried out under the supervision and with the participation of our management, including our chief executive officer and chief financial officer. Based upon that evaluation, the chief executive officer and chief financial officer concluded that the design and operation of these disclosure controls and procedures were effective as of September 30, 2020, the end of the period covered by this report.

Changes in Internal Control over Financial Reporting

During the quarter ended September 30, 2020, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

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. Except as described below, there have been no material changes to the legal proceedings previously disclosed in our Annual Report on Form 10-K, as updated in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2020 and June 30, 2020.

SEC Matter

As previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 10-K”), we have been cooperating with the staff of the SEC in connection with a formal investigation regarding Andeavor’s historical share repurchase activity and an informal investigation regarding MPC’s share repurchase activity. On October 15, 2020, the SEC announced an agreement with Andeavor LLC, successor-by-merger to Andeavor and a wholly owned subsidiary of MPC, to settle the investigation regarding Andeavor’s historical share repurchase activity. As part of the settlement with the SEC, Andeavor LLC agreed to pay a $20 million penalty and consent to the entry of an Administrative Order containing findings that Andeavor violated Section 13(b)(2)(B) of the Securities Exchange Act of 1934, as amended, and ordering Andeavor LLC to cease and desist from committing or causing any violations and any future violations of that provision. Andeavor LLC neither admitted nor denied the SEC’s findings. Following the announcement of the settlement with Andeavor LLC, the SEC staff informed us that it has concluded its formal and informal investigations and does not intend to recommend an enforcement action. This settlement did not have a material adverse effect on our results of operations, financial position or cash flows.

Litigation

As described in our 2019 10-K and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, governmental and other entities in California, Hawaii, New York, Maryland and Rhode Island have filed lawsuits against coal, gas, oil and petroleum companies, including the Company. The lawsuits allege damages as a result of climate change and the plaintiffs are seeking unspecified damages and abatement under various tort theories.

On September 9, the City of Charleston, South Carolina filed suit in South Carolina’s Court of Common Pleas, Ninth Judicial Circuit, against 24 oil and gas industry defendants, including MPC, MPC LP and Speedway. On September 10, the State of Delaware filed suit in the Superior Court of the State of Delaware against 31 oil and gas industry defendants, including MPC, MPC LP and Speedway. On October 12, 2020, the County of Maui, Hawaii, filed suit in the Circuit Court of the Second Circuit for the State of Hawaii against 20 oil and gas industry defendants, including MPC. The claims made in these lawsuits are substantially similar to those made in MPC’s previously disclosed climate change litigation.

At this early stage, the ultimate outcome of these matters remains uncertain, and neither the likelihood of an unfavorable outcome nor the ultimate liability, if any, can be determined.

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 or DAPL, MPLX has entered into a Contingent Equity Contribution Agreement whereby MPLX LP, 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.

As previously disclosed in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, 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.

Table of Contents

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. In the D.D.C., briefing is ongoing 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. 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 also 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.

Tesoro High Plains Pipeline

In early July, MPLX received a Notification of Trespass Determination from the Bureau of Indian Affairs (“BIA”) relating to a portion of the 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 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.

Environmental Proceedings

As previously disclosed in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2020, MPLX had previously reached a settlement in principle to resolve allegations relating to its compliance at its Sarsen facility. In August 2020, MPLX finalized a settlement with the EPA, which resolved this matter with a cash penalty of $150,025.

ITEM 1A. RISK FACTORS

There have been no material changes from the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019, as updated in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2020 and June 30, 2020.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The following table sets forth a summary of our purchases during the quarter ended September 30, 2020, of equity securities that are registered by MPC pursuant to Section 12 of the Securities Exchange Act of 1934, as amended.
