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 with more than 3 million barrels per day of crude oil capacity across 16 refineries. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to consumers through our Retail business segment and to independent entrepreneurs who operate approximately 6,900 branded outlets. Our retail operations own and operate approximately 3,880 retail transportation fuel and convenience stores across the United States and 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 October 31, 2019, we announced our intention to separate our retail transportation fuel and convenience store business, which is operated primarily under the Speedway brand, into an independent, publicly traded company through a tax-free distribution to MPC shareholders of publicly traded stock in the new independent retail transportation fuel and convenience store company. This transaction is targeted to be completed in the fourth quarter of 2020, however timing could change given the COVID-19 related impacts to the business environment and access to capital markets. This transaction is subject to market, regulatory and certain other conditions, including final approval by the MPC Board of Directors, receipt of customary assurances regarding the intended tax-free nature of the transaction, and the effectiveness of a registration statement to be filed with the SEC. The Speedway business is currently a reporting unit within our Retail segment. MPC will retain its direct dealer business, which is also included in the Retail segment as currently reported. Subsequent to the completion of the separation, the historical results of the Speedway business will be presented as discontinued operations in our consolidated financial statements.

Basis of Presentation

All significant intercompany transactions and accounts have been eliminated.

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 months ended March 31, 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 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 March 31, 2020, we reported $5,583 million of accounts and notes receivable, net of allowances of $18 million.

Table of Contents

We are also exposed to credit losses from off-balance sheet exposures, such as guarantees of joint venture debt. See Note 22 for more information on these off-balance sheet exposures.

We also adopted the following ASU during the first three 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

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. 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 March 31, 2020 we owned approximately 63 percent of the outstanding MPLX common units.

MPLX’s Acquisition of ANDX

On July 30, 2019, MPLX completed its acquisition of Andeavor Logistics LP (“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, 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.

4. IMPAIRMENTS

The recent 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 significantly reduced global economic activity and resulted in airlines dramatically cutting back on flights and a decrease in motor vehicle use at a time when seasonal driving patterns typically result in an increase of consumer demand for gasoline. In addition, recent global geopolitical events and macroeconomic conditions have exacerbated the decline in crude oil prices and have contributed to an increase in crude oil price volatility. The decrease in the demand for refined petroleum products coupled with the decline in the price of crude oil has resulted in a significant decrease in the price of the refined petroleum products we produce and sell.

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 assessments to identify any potential impairments of the carrying values of our assets. During the first quarter of 2020, we recognized impairment charges related to goodwill, equity method investments and long-lived assets (including intangibles).

The table below provides information related to the impairments recognized during the first quarter of 2020 and the location of these impairments within the consolidated statements of income.



(In millions)	Income Statement Line	Impairment
Goodwill	Impairment expense	$	7,330
Equity method investments	Income (loss) from equity method investments	1,315
Long-lived assets	Impairment expense	492
Total impairments		$	9,137

Goodwill

During the first quarter of 2020, we recorded an impairment of goodwill. 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 guidance related to the slowing of drilling activity, which has reduced production growth forecasts from MPLX’s producer customers.

The fair value of the reporting units for the goodwill impairment analysis was 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			Retail		Midstream			Total
Balance at January 1, 2020	$	5,572		$	4,951	$	9,517		$	20,040
Impairments	(5,516		)	—		(1,814		)	(7,330		)
Transfers	(56		)	—		56			—
Balance at March 31, 2020	$	—		$	4,951	$	7,759		$	12,710

Equity Method Investments

During the first quarter of 2020, we recorded equity method investment impairment charges, 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, company-owned convenience store locations for Retail 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 as a result of significant impacts to the Refining & Marketing segment forecasted 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. All other refinery asset groups undiscounted estimated pretax cash flows exceeded the carrying value by at least 21 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. 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.

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 to impairment expense on the consolidated statements of income. The fair value measurements for the Gallup refinery assets represent Level 3 measurements.

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 impacts to forecasted 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

Table of Contents

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.

5. 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 substantive 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 22 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.

The following table presents balance sheet information for the assets and liabilities of MPLX, which are included in our balance sheets.

Sales to related parties, which are included in sales and other operating revenues, consist primarily of sales of refined products to PFJ Southeast, an equity affiliate which owns and operates travel plazas primarily in the Southeast region of the United States.

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

7. LOSS PER SHARE

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

8. EQUITY

As of March 31, 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 discontinued at any time.

Total share repurchases were as follows for the respective periods:

9. SEGMENT INFORMATION

We have three reportable segments: Refining & Marketing, Retail 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 16 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 our Retail business segment and to independent entrepreneurs who operate primarily Marathon^® branded outlets.


•	Retail – sells transportation fuels and convenience products in the retail market across the United States through company-owned and operated convenience stores, primarily under the Speedway^® brand, and long-term fuel supply contracts with direct dealers who operate locations mainly under the ARCO^® brand.


•	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 and Retail segments. In addition, certain items that affect comparability (as determined by the chief operating decision maker) are not allocated to the reportable segments.

11. INCOME TAXES

We have historically provided for income taxes during interim reporting periods based on an estimate of the annual effective tax rate applied to the income for the 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 in response to the COVID-19 pandemic. The CARES Act contains numerous income tax provisions, some of which materially impact MPC's calculation of income taxes including:


•	Reducing 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.

We recorded an overall income tax benefit of $1.9 billion for the three months ended March 31, 2020, of which $411 million was attributable to the expected NOL carryback provided for under the CARES Act. The combined federal, state and foreign income tax rate was 16 percent for the three months ended March 31, 2020. Our effective tax benefit rate was lower than the statutory rate primarily due to a significant amount of our pre-tax loss consisting of non-tax deductible goodwill impairment charges, partially offset by a favorable rate effect of the CARES Act legislation. Additionally, our effective tax rate is generally benefited by our noncontrolling interest in MPLX, but this benefit was lower for the three months ended March 31, 2020 compared to the three months ended March 31, 2019 due to impairment charges recorded by MPLX. We recorded an income tax receivable of $1.3 billion in other noncurrent assets to reflect our estimate of the tax benefit we will realize at the time of our 2020 tax return filing which is expected during the second half of 2021. A reconciliation of the federal statutory income tax rate applied to income (loss) before income taxes to the (benefit) provision for income taxes follows:

Goodwill impairment	(10	)	—
Noncontrolling interests	(1	)	(4	)
CARES Act legislation	3		—
Other	1		—
Effective tax rate	16	%	29	%

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 March 31, 2020, we had $27 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 22 for indemnification information.

12. INVENTORIES



(In millions)	March 31, 2020			December 31, 2019
Crude oil	$	3,717		$	3,472
Refined products	5,700			5,548
Materials and supplies	1,000			996

Inventories before LCM inventory valuation reserve	10,665			10,243
LCM inventory valuation reserve	(3,220		)	—
Total	$	7,445		$	10,243

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 if the LIFO cost basis of these inventories may have to be written down to market values. At March 31, 2020, market values for these inventories were lower than their LIFO cost basis and, as a result, we recorded an inventory valuation charge of $3.22 billion to value these inventories at the lower of cost or market. 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.

The cost of inventories of crude oil and refined products and merchandise is determined primarily under the LIFO method. There were no LIFO inventory liquidations recognized for the three months ended March 31, 2020.

13. EQUITY METHOD INVESTMENTS

Significant Equity Method Investments

Summarized financial information, in the aggregate, for our significant equity method investments on a 100 percent basis were as follows:



	Three Months Ended March 31,
(In millions)	2020			2019
Revenues and other income	$	1,072		$	1,628
Income (loss) from operations	(20		)	336
Net income (loss)	(44		)	314

Capline LLC

During the three months ended March 31, 2019, we executed agreements with Capline Pipeline Company LLC (“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. Crude oil service is expected to begin in the first half of 2021.

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.

15. FAIR VALUE MEASUREMENTS

Fair Values—Recurring

The following tables present assets and liabilities accounted for at fair value on a recurring basis as of March 31, 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 March 31, 2020, cash collateral of $67 million was netted with mark-to-market assets and $16 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 March 31, 2020 used significant unobservable inputs including: (1) NGL prices interpolated and extrapolated due to inactive markets ranging from $0.26 to $0.68 per gallon with a weighted average of $0.39 per gallon per the current term of the embedded derivative and (2) the probability of renewal of 95 percent for the first five-year term and 83.5 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. Beyond the embedded derivative discussed above, we had no outstanding commodity contracts as of March 31, 2020.

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 $31.0 billion and $27.7 billion at March 31, 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.

16. DERIVATIVES

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

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

The following table presents the fair value of derivative instruments as of March 31, 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.

22. COMMITMENTS AND CONTINGENCIES

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

Environmental Matters

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

Table of Contents

At March 31, 2020 and December 31, 2019, accrued liabilities for remediation totaled $418 million and $433 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 $29 million and $29 million at March 31, 2020 and December 31, 2019, respectively.

Governmental and other entities in California, Hawaii, Maryland, New York 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. 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 on 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 Lawsuits

In May 2015, the Kentucky attorney general filed a lawsuit against our wholly owned subsidiary, Marathon Petroleum Company LP (“MPC LP”), in the United States District Court for the Western District of Kentucky asserting claims under federal and state antitrust statutes, the Kentucky Consumer Protection Act, and state common law. The complaint, as amended in July 2015, alleges that MPC LP used deed restrictions, supply agreements with customers and exchange agreements with competitors to unreasonably restrain trade in areas within Kentucky and seeks declaratory relief, unspecified damages, civil penalties, restitution and disgorgement of profits. At this stage, the ultimate outcome of this litigation remains uncertain, and neither the likelihood of an unfavorable outcome nor the ultimate liability, if any, can be determined, and we are unable to estimate a reasonably possible loss (or range of loss) for this matter. We intend to vigorously defend ourselves in this matter.

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—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 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 March 31, 2020.

In connection with our 25 percent interest in Gray Oak Pipeline, LLC (“Gray Oak Pipeline”), we have entered into an Equity Contribution Agreement obligating us to make certain equity contributions to Gray Oak Pipeline to support its obligations under a construction loan facility. Gray Oak oil pipeline 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 requires 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. Gray Oak may borrow up to $1.43 billion under the construction loan facility (after giving effect to the exercise of all options to increase its borrowing capacity). As of March 31, 2020, our maximum potential undiscounted payments under the Equity Contribution Agreement for the debt principal totaled $345 million.

In connection with MPLX’s 9.19 percent indirect interest in a joint venture 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, have 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 ordered the U.S. Army Corps of Engineers, which granted permits for the Bakken Pipeline system, to conduct a full environmental impact statement (“EIS”), and further requested briefing on whether an easement permit necessary for the operation of the Bakken Pipeline system should be vacated while the EIS is being prepared. If the permit is vacated pending completion of the EIS and the vacatur is deemed temporary, MPLX would have to contribute its 9.19 percent pro rata share of funds required to pay interest accruing on the notes while the pipeline is shutdown and 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 court vacates the permit and such action 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, if any. As of March 31, 2020, our maximum potential undiscounted payments under the Contingent Equity Contribution Agreement was approximately $230 million.

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 March 31, 2020, our maximum potential undiscounted payments under this agreement for debt principal totaled $125 million.

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 March 31, 2020, our maximum potential undiscounted payments under this arrangement was $118 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 $103 million as of March 31, 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 March 31, 2020, our contractual commitments to acquire property, plant and equipment and advance funds to equity method investees totaled $626 million.

Table of Contents

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.

23. SUBSEQUENT EVENTS

Subsequent to the end of the quarter, we completed a number of financing activities to enhance our liquidity as described below.

Additional MPC 364-Day Bank Revolving Credit Facility

On April 27, 2020, MPC entered into a credit agreement with a syndicate of lenders providing for an additional $1 billion 364-day revolving credit facility. The credit agreement for the additional 364-day revolving credit facility contains representations and warranties, affirmative and negative covenants and events of default that we consider customary for agreements of their nature and type and substantially similar to those contained in our existing $5.0 billion five-year revolving credit facility and $1.0 billion 364-day revolving credit facility.

MPC Senior Notes Issuance

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 amounts outstanding under its five-year revolving credit facility.

The following table shows our available credit capacity, excluding MPLX, as of May 5, 2020.

CORPORATE OVERVIEW

We are an independent petroleum refining and marketing, retail and midstream company. We own and operate the nation’s largest refining system through 16 refineries, located in the Gulf Coast, Mid-Continent and West Coast regions of the United States, with an aggregate crude oil refining capacity of approximately 3.1 mmbpcd. 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 6,900 branded outlets operated by independent entrepreneurs in 35 states, the District of Columbia and Mexico. We believe our Retail segment operates the second largest chain of company-owned and operated retail gasoline and convenience stores in the United States, with approximately 3,880 convenience stores, primarily under the Speedway brand, and 1,070 direct dealer locations, primarily under the ARCO brand, across the United States.

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 March 31, 2020, we owned, leased or had ownership interests in approximately 17,200 miles of crude oil and refined product pipelines to deliver crude oil to our refineries and other locations and refined products to wholesale and retail market areas. 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

Table of Contents

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 three reportable operating segments: Refining & Marketing, Retail, and Midstream. Each of these segments is organized and managed based upon the nature of the products and services they offer.

•


•	Retail – sells transportation fuels and convenience products in the retail market across the United States through company-owned and operated convenience stores, primarily under the Speedway^® brand, and long-term fuel supply contracts with direct dealers who operate locations mainly under the ARCO^® brand.


•	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

Business Update

This has in turn significantly reduced global economic activity and resulted in airlines dramatically cutting back on flights and a decrease in motor vehicle use at a time when seasonal driving patterns typically result in an increase of consumer demand for gasoline. As a result, there has also been a decline in the demand for the refined petroleum products that we manufacture and sell.

In addition, recent global geopolitical events and macroeconomic conditions have exacerbated the decline in crude oil prices and have contributed to an increase in crude oil price volatility.

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

The price of refined products we sell and the feedstocks we purchase impact our revenues, income from operations, net income and cash flows. 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 March 31, 2020, market values for these inventories were lower than their LIFO cost basis and, as a result, we recorded an inventory valuation charge of $3.22 billion to value these inventories at the lower of cost or market. 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 are actively responding to the impacts that these matters are having on our business. During March and continuing through April 2020, we started reducing the amount of crude oil processed at our refineries in response to the decreased demand for our products, and we temporarily idled portions of refining capacity to further limit production. In addition to these measures to address our operations, we are addressing our liquidity as outlined below.

•

We expect to defer or delay certain capital expenditures of approximately $1.35 billion, or approximately 30 percent, which is expected to reduce planned spending levels down to $3.0 billion for 2020. The reductions are planned across all segments of the business, including: $250 million in Refining & Marketing; $770 million in Midstream, which includes MPLX; $250 million in Retail; and $80 million in Corporate. 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.

Table of Contents


•	We have taken actions to reduce forecasted annual operating expenses by approximately of $950 million, primarily through reductions of fixed costs and deferral of certain expense projects, which includes $200 million of operating expense reductions at MPLX.


•	Throughput levels have been reduced across the organization including the temporary idling of some facilities. The company plans to continue to monitor market conditions and optimize crude oil acquisition, refining run rates, and logistics systems to respond on a regional basis.


•	Share repurchases have temporarily been suspended. The company will evaluate the timing of future repurchases as market conditions evolve.


•	On April 27, 2020, we entered into an additional $1 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 amounts outstanding on the five-year revolving credit facility.


•	The company continues to evaluate further actions to enhance liquidity.

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.

Strategic Actions to Enhance Shareholder Value

On October 31, 2019, we announced our intention to separate our retail transportation fuel and convenience store business, which is operated primarily under the Speedway brand, into an independent, publicly traded company through a tax-free distribution to MPC shareholders of publicly traded stock in the new independent retail transportation fuel and convenience store company. This transaction is targeted to be completed in the fourth quarter of 2020, however timing could change given the COVID-19 related impacts to the business environment and access to capital markets. This transaction is subject to market, regulatory and certain other conditions, including final approval by MPC’s board of directors, receipt of customary assurances regarding the intended tax-free nature of the transaction, and the effectiveness of a registration statement to be filed with the SEC. The Speedway business is currently a reporting unit within our Retail segment. MPC will retain its direct dealer business, which is also included in the Retail segment as currently reported.

On March 18, 2020, we announced that MPC’s board of directors unanimously decided to maintain MPC’s current midstream structure, with the company remaining 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.

EXECUTIVE SUMMARY

Table of Contents

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 loss attributable to MPC was $(9.23) billion, or $(14.25) per diluted share, in the first quarter of 2020 compared to $(7) million, or $(0.01) per diluted share, for the first quarter of 2019. The change was primarily due to impairment charges of $7.82 billion to goodwill and long-lived assets, an LCM charge of $3.22 billion and impairments of equity method investments of $1.32 billion during the current period primarily driven by the effects of COVID-19 and the decline in commodity prices. Increased income from operations in our Retail segment due to higher fuel and merchandise margins was partially offset by a higher loss from operations in our Refining & Marketing segment due to decreases in refined product sales volumes and prices during the current quarter.

Inventories are stated at the lower of cost or market. Costs of crude oil, refinery feedstocks and refined products are stated under the LIFO inventory costing method and aggregated on a consolidated basis for purposes of assessing if the cost basis of these inventories may have to be written down to market values. 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. The impairments of goodwill, equity method investments and long-lived assets are based on fair value determinations, which 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 impairments recognized in the first three months of 2020 will prove to be an accurate prediction of the future.

Refer to the Results of Operations section for a discussion of consolidated financial results and segment results for the first quarter of 2020 as compared to the first quarter of 2019.

MPLX

We owned approximately 666 million MPLX common units at March 31, 2020 with a market value of $7.74 billion based on the March 31, 2020 closing price of $11.62 per common unit. On April 28, 2020, MPLX declared a quarterly cash distribution of $0.6875 per common unit payable on May 15, 2020. As a result, MPLX will make distributions totaling $728 million to its common unitholders. MPC’s portion of these distributions is approximately $458 million.

We received limited partner distributions of $446 million from MPLX in the three months ended March 31, 2020 and $473 million from MPLX and ANDX combined in the three months ended March 31, 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.

See Note 3 to the unaudited consolidated financial statements for additional information on MPLX.

Share Repurchases

During the three months ended March 31, 2020, we did not repurchase any of our common stock, which helped preserve our liquidity during the COVID-19 pandemic. 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 as of March 31, 2020. We will evaluate the timing to resume any future repurchases as market conditions evolve. See Note 8 to the unaudited consolidated financial statements.

Liquidity

As of March 31, 2020, we had cash and cash equivalents of approximately $1.63 billion, excluding MPLX cash and cash equivalents of $57 million, $3.0 billion available under a five-year bank revolving credit facility, $1.0 billion available under a 364-day bank revolving credit facility, and $750 million available under our trade receivables securitization facility resulting in cash and available liquidity of $6.38 billion. MPC drew $2.0 billion on the five-year bank revolving credit facility in the first quarter of 2020. This borrowing was undertaken to provide financial flexibility given the recent commodity price downturn and the significant working capital impact associated with the decline in crude prices. The company has made short-term borrowings to manage the impact of commodity prices on working capital in the past and expects to do so from time to time in the future.

MPLX’s liquidity totaled $4.31 billion at March 31, 2020. As of March 31, 2020, MPLX had cash and cash equivalents of $57 million, $2.75 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.

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. 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.

Table of Contents

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.

Retail

Retail segment profitability is impacted by fuel and merchandise margin. Fuel margin for gasoline and distillate is the price paid by consumers or direct dealers less the cost of refined products, including transportation, consumer excise taxes and bankcard processing fees (where applicable). Gasoline and distillate prices are volatile and are impacted by changes in supply and demand in the regions where we operate. Numerous factors impact gasoline and distillate demand throughout the year, including local competition, seasonal demand fluctuations, the available wholesale supply, the level of economic activity in our marketing areas and weather conditions.

The margin on merchandise sold at our convenience stores historically has been less volatile and has contributed substantially to our Retail segment margin. Our Retail convenience stores offer a wide variety of merchandise, including prepared foods, beverages and non-food items.

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.

^(a)	The 2020 period includes $1.32 billion of impairment expense. See Note 4 to the unaudited consolidated financial statements for further information.

First Quarter 2020 Compared to First Quarter 2019

Net loss attributable to MPC increased $9.23 billion in the first quarter of 2020 compared to the first quarter of 2019 primarily due to impairment expenses for goodwill and long-lived assets of $7.82 billion, an inventory market valuation adjustment of $3.22 billion and impairments of equity method investments of $1.32 billion during the period.

Revenues and other income decreased $4.52 billion primarily due to:


•	decreased sales and other operating revenues of $3.04 billion primarily due to decreased Refining & Marketing segment refined product sales volumes, which decreased 81 mbpd, and decreased average refined product sales prices of $0.22 per gallon largely 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 of $210 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.

Costs and expenses increased $7.97 billion primarily due to:


•	decreased cost of revenues of $3.14 billion mainly due to lower refined product sales volumes, which decreased 81 mbpd primarily due to reduced travel and business operations associated with the COVID-19 pandemic;

Table of Contents


•	an inventory market valuation adjustment charge of $3.22 billion primarily driven by the effects of COVID-19 and the decline in commodity prices;


•	impairment expense of $7.82 billion recorded for goodwill and long-lived assets of $7.33 billion and $492 million, respectively, primarily driven by the effects of COVID-19 and the decline in commodity prices; and

•

increased other taxes of $65 million primarily due to increased property and environmental taxes of approximately $34 million and $21 million, respectively. Property taxes increased in the current period mainly due to the absence of property tax refunds received in the first quarter of 2019 and environmental taxes increased largely due to the reinstatement of the Oil Spill Tax in 2020 after not being active in 2019.

Benefit for income taxes was $1.94 billion at March 31, 2020 compared to provision for income taxes of $104 million at March 31, 2019, primarily due to decreased income before income taxes of $12.52 billion. The combined federal, state and foreign income tax rate was a tax benefit of 16 percent for the three months ended March 31, 2020. The effective tax rate for the three months ended March 31, 2020 was less 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 a favorable rate effect of the CARES Act legislation. Additionally, our effective tax rate is generally benefited by our noncontrolling interest in MPLX, but this benefit was lower for the three months ended March 31, 2020 compared to the three months ended March 31, 2019 due to impairment charges recorded by MPLX. The combined federal, state and foreign income tax rate was 29 percent for the three months ended March 31, 2019. The effective tax rate for the three months ended March 31, 2019 was greater 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 partially offset by permanent tax differences related to net income attributable to noncontrolling interests.

Non-controlling interests decreased $1.25 billion due to MPLX’s net loss primarily resulting from impairment expense recognized during the quarter.

First Quarter 2020 Compared to First Quarter 2019

Refining & Marketing segment revenues decreased $3.19 billion primarily due to lower refined product sales volumes, which decreased 81 mbpd, and decreased average refined product sales prices of $0.22 per gallon. These decreases were primarily the result of reduced travel and business operations associated with the COVID-19 pandemic.

Refinery crude oil capacity utilization was 91 percent and net refinery throughputs decreased 90 mbpd during the first quarter of 2020.

Refining & Marketing segment loss from operations increased $288 million primarily due to lower blended crack spreads and higher planned turnaround expenses.

Refining & Marketing margin was $11.30 per barrel for the first quarter of 2020 compared to $11.17 per barrel for the first 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 $490 million on Refining & Marketing margin for the first quarter of 2020 compared to the first quarter of 2019, primarily due to lower WTI crack spreads and narrower sweet crude oil differentials, partially offset by wider sour crude oil differentials. Our reported Refining & Marketing margin differs from market indicators due to the mix of crudes purchased and their costs, the effect of market structure on our crude oil acquisition prices, the effect of RIN prices on the crack spread, and other items like refinery yields and other feedstock variances. These factors had an estimated net positive effect of approximately $470 million on Refining & Marketing segment income in the first quarter of 2020 compared to the first quarter of 2019.

Refining operating costs, excluding depreciation and amortization, increased $0.42 per barrel primarily due to higher engineered projects, maintenance costs and taxes, partially offset by lower energy costs. While, distribution costs, excluding depreciation and amortization, were flat as compared to first quarter of 2019, the lower throughput resulted in an $0.08

Table of Contents

increase in these costs on a per barrel basis. Distribution costs, excluding depreciation and amortization, include fees paid to MPLX of $858 million and $786 million for the first quarter of 2020 and 2019, respectively. Refining planned turnaround costs increased $0.53 per barrel due to the timing of turnaround activity. Depreciation and amortization per barrel increased by $0.10 per barrel.

First Quarter 2020 Compared to First Quarter 2019

Retail segment revenues decreased $607 million primarily due to decreased fuel sales partially offset by increased merchandise sales. Total fuel sales volumes decreased 280 million gallons and average fuel sales prices decreased $0.17 per gallon. Merchandise sales increased $48 million. These changes were primarily due to the effects of the COVID-19 pandemic which resulted in reduced fuel sales from restricted travel, social distancing and reduced business operations and increased merchandise sales primarily of cigarettes, beer and wine, and other merchandise. 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.

Retail segment income from operations increased $349 million largely driven by higher fuel margins partially offset by an increase in operating expenses. Retail fuel margin increased to 32.91 cents per gallon in the first quarter of 2020, from 17.15 cents per gallon in the first quarter of 2019.

First Quarter 2020 Compared to First Quarter 2019

Corporate and other unallocated items increased $36 million primarily due to an information systems integration project and incremental legal expenses.

During the first quarter of 2020, we recorded impairment charges of approximately $9.14 billion, which includes $7.82 billion related to goodwill and long-lived assets and impairments of equity method investments of $1.32 billion, and an inventory market valuation adjustment charge of $3.22 billion primarily driven by the effects of COVID-19 and the decline in commodity prices.

Other unallocated items include transaction-related costs of $35 million for the first quarter of 2020 associated with the Speedway separation, Midstream strategic review and other related activities and $91 million for the first quarter of 2019 largely related to the recognition of an obligation for vacation benefits provided to former Andeavor employees as part of the Andeavor acquisition. In the first quarter 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.

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 was approximately $1.69 billion at March 31, 2020 compared to $1.53 billion at December 31, 2019. Net cash provided by (used in) operating activities, investing activities and financing activities are presented in the following table.



	Three Months Ended March 31,

Total increase (decrease) in cash	$	165		$	(817	)

Net cash provided by operating activities decreased $2.39 billion in the first three months of 2020 compared to the first three months of 2019, primarily due to an unfavorable change in working capital of $2.52 billion mainly due to a decrease in accounts payable. Changes in working capital exclude changes in short-term debt.

Changes in working capital, excluding changes in short-term debt, were a net $2.03 billion use of cash in the first three months of 2020 compared to a net $489 million source of cash in the first three months of 2019.

For the first three months of 2020, changes in working capital, excluding the LCM reserve and changes in short-term debt, were a net $2.03 billion use of cash primarily due to the effects of decreasing energy commodity prices at the end of the period on working capital. Accounts payable decreased primarily due to a decrease in crude prices. Current receivables decreased primarily due to lower crude and refined product prices partially offset by an increase in crude volumes. Excluding the LCM reserve,inventories increased due to increases in crude and refined product inventories.

For the first three months of 2019, changes in working capital, excluding changes in short-term debt, were a net $489 million source of cash primarily due to the effects of increases in energy commodity prices at the end of the period on working capital. Accounts payable increased primarily due to an increase in crude prices. Current receivables increased primarily due to higher refined product and crude prices and higher crude sales volumes. Inventories decreased due to decreases in refined product and merchandise inventories, partially offset by increases in crude and materials and supplies inventories.

Net cash used in investing activities decreased $432 million in the first three months of 2020 compared to the first three months of 2019, primarily due to the following:


•	a decrease in additions to property, plant and equipment of $179 million primarily due to decreased capital expenditures in the first three months of 2020 in our Midstream and Refining & Marketing segments; and


•	a decrease in net investments of $231 million largely due to investments in the first quarter of 2019 connection with the construction of the Gray Oak Pipeline, which began initial start-up in the fourth quarter of 2019.

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 $2.73 billion source of cash in the first three months of 2020 compared to a net $573 million source of cash in the first three months of 2019. During the first three months of 2020, MPC had borrowings of $2.0 billion under its revolving credit facility, borrowed and repaid $925 million under its trade receivables facility and MPLX had net borrowings of $750 million under its revolving credit facility. During the first three months of 2019, MPLX had net borrowings of $425 million under its revolving credit facility and ANDX had net borrowings of $159 million under its revolving credit facility. MPLX completed its acquisition of ANDX on July 30, 2019.


•	Cash used in common stock repurchases decreased $885 million in the first three months of 2020 compared to the first three months of 2019. There were no share repurchases in the first three months of 2020 compared to $885 million in the first three months of 2019. See Note 8 to the unaudited consolidated financial statements for further discussion of share repurchases.

•

Cash used in dividend payments increased $23 million in the first three months of 2020 compared to the first three months of 2019, primarily due to a $0.05 per share increase in our base dividend, partially offset by a reduction of shares resulting from share repurchases in 2019. Our dividend payments were $0.58 per common share in the first three months of 2020 compared to $0.53 per common share in the first three months of 2019.


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

Capital Resources

MPC, Excluding MPLX

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

Our liquidity, excluding MPLX, totaled $6.38 billion at March 31, 2020 consisting of:



	March 31, 2020
(In millions)	Total Capacity		Outstanding Borrowings		Available Capacity
Bank revolving credit facility^(a)(b)	$	5,000	$	2,001	$	2,999

Trade receivables facility^(c)	750		—		750
Total	$	6,750	$	2,001	$	4,749
Cash and cash equivalents^(d)					1,633
Total liquidity					$	6,382


^(a)	Excludes MPLX’s $3.50 billion bank revolving credit facility, which had approximately $2.75 billion available as of March 31, 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. As of April 30, 2020 eligible trade receivables supported borrowings of approximately $517 million.


^(d)	Excludes MPLX cash and cash equivalents of $57 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, the repurchase of shares of our common stock, dividend payments, defined benefit plan contributions, repayment of debt maturities and other amounts that may ultimately be paid in connection with contingencies.

Table of Contents

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 March 31, 2020, we had no commercial paper borrowings outstanding.

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 amounts outstanding under its five-year revolving credit facility.

The following table shows our available credit capacity, excluding MPLX, as of May 5, 2020.



(Dollars in millions)	Total Capacity		Outstanding Borrowings		Outstanding Letters of Credit		Available Capacity		Expiration
MPC 364-day bank revolving credit facility	$	1,000	$	—	$	—	$	1,000	September 2020

MPC trade receivables securitization facility^(b)	517		—		—		517		July 2021
Available capacity, excluding MPLX, as of May 5, 2020							6,766


^(a)	Borrowed $2 billion on March 30, 2020 and $1.5 billion in April. Repaid $2.75 billion in May.


^(b)	Availability under our $750 million trade receivables facility is a function of eligible trade receivables, which will be lower in a sustained lower price environment for refined products. As of April 30, 2020 eligible trade receivables supported borrowings of approximately $517 million.

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 March 31, 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 0.31 to 1.00.

Our intention is to maintain an investment-grade credit profile. As of May 5, 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 17 to the unaudited consolidated financial statements for further discussion of our debt.

MPLX

MPLX’s liquidity totaled $4.31 billion at March 31, 2020 consisting of:



	March 31, 2020
(In millions)	Total Capacity		Outstanding Borrowings		Available Capacity
MPLX LP - bank revolving credit facility	$	3,500	$	750	$	2,750
MPC Intercompany Loan Agreement	1,500		—		1,500
Total	$	5,000	$	750	$	4,250
Cash and cash equivalents					57
Total liquidity					$	4,307

The MPLX credit agreement and term loan agreement contain 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 March 31, 2020, MPLX was in compliance with the covenants, including the financial covenant with a ratio of Consolidated Total Debt to Consolidated EBITDA of 3.80 to 1.0.

Our intention is to maintain an investment-grade credit profile for MPLX. As of May 5, 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 17 for further discussion of MPLX’s debt.

Capital Requirements

Capital Investment Plan

MPC's capital investment plan 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, Retail and Corporate as well as a portion of the planned capital investments in Midstream. 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 as detailed in the table below. 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.

^(a)	Includes capitalized interest of $29 million and $31 million for the three months ended March 31, 2020 and 2019, respectively.

Capital expenditures and investments in affiliates during the three months ended March 31, 2020 were primarily for Midstream and Refining & Marketing segment projects and investments in affiliates.

Other Capital Requirements

During the three months ended March 31, 2020, we contributed $3 million to our funded pension plans. We may choose to make additional contributions to our pension plans.

On April 29, 2020, our board of directors approved a dividend of $0.58 per share on common stock. The dividend is payable June 10, 2020, to shareholders of record as of the close of business on May 20, 2020.

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 three months ended March 31, 2020, we did not repurchase any of our common stock, which helped preserve our liquidity during the COVID-19 pandemic. 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 March 31, 2020. We will evaluate the timing to resume any future repurchases as market conditions evolve. The table below summarizes our total share repurchases for the three months ended March 31, 2020 and 2019. See Note 8 to the unaudited consolidated financial statements for further discussion of the share repurchase plans.

Table of Contents



	Three Months Ended March 31,

Number of shares repurchased	—		14
Cash paid for shares repurchased	$	—	$	885
Average cost per share	$	—	$	62.98

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 discontinued at any time.

Contractual Cash Obligations

As of March 31, 2020, our contractual cash obligations included long-term debt, capital and operating lease obligations, purchase obligations and other long-term liabilities. During the first three months of 2020, our long-term debt commitments increased approximately $2.55 billion primarily due to borrowings under the MPC and MPLX bank revolving credit facilities.

During the quarter our contractual cash obligations for crude oil decreased primarily as a result of the decrease in crude prices during the period. 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 22 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 three months ended March 31, 2020.

CRITICAL ACCOUNTING ESTIMATES

As of March 31, 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.

Table of Contents

•

Future volumes. Our estimates of future refinery, retail, pipeline throughput and natural gas and natural gas liquid processing volumes are based on internal forecasts prepared by our Refining & Marketing, Retail 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.


•	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 or retail fuel 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, company-owned convenience store locations for Retail 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 as a result of significant impacts to the Refining & Marketing segment forecasted 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. All other refinery asset groups undiscounted estimated pretax cash flows exceeded the carrying value by at least 21 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. 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 these additional refinery asset groups exceed the undiscounted estimated pretax cash flows of these refinery asset groups, which would result in future impairment charges.

It was determined that the fair value of the Gallup refinery’s property, plant and equipment (“PP&E”) was less than the carrying value. As a result, we recorded a charge of $142 million to impairment expense on the consolidated statements of income. The fair value measurements for the Gallup refinery assets represent Level 3 measurements.

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 impacts to forecasted 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 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 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

Table of Contents

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 recent outbreak of COVID-19 and its development into a pandemic and the recent decline in commodity prices have had on our business. Due to these developments, we performed impairment assessments 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 which make up this reporting unit were acquired through the merger with ANDX. We accounted for the October 1, 2018 acquisition of Andeavor (including acquiring 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 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 March 31, 2020 we had $5.66 billion of equity method investments recorded on the Consolidated Balance Sheets.

Table of Contents

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 15 and 16 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 March 31, 2020 and 2019, respectively.



	Three Months Ended March 31,
(In millions)	2020		2019
Realized gain on settled derivative positions	$	2	$	39
Unrealized gain (loss) on open net derivative positions	213		(139		)
Net gain (loss)	$	215	$	(100	)

See Note 16 to the unaudited consolidated financial statements for additional information on our open derivative positions at March 31, 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 March 31, 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 March 31, 2020
Crude	$	(56	)	$	(140	)	$	58		$	144
Refined products	12			29			(12		)	(29		)
Blending products	(2		)	(5		)	2			5
Embedded derivatives	(5		)	(11		)	5			11

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 March 31, 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 March 31, 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 March 31, 2020^(a)		Change in Fair Value^(b)		Change in Net Income for the Three Months Ended March 31, 2020^(c)
Long-term debt
Fixed-rate	$	22,289	$	1,772	n/a
Variable-rate	3,751		n/a		8


^(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 March 31, 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 three months ended March 31, 2020.

At March 31, 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 15 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 March 31, 2020, the end of the period covered by this report.

Changes in Internal Control over Financial Reporting

During the quarter ended March 31, 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.

In connection with MPLX’s 9.19 percent indirect interest in a joint venture 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 whereby MPLX LP, along with the other joint venture owners in the Bakken Pipeline system, have 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 Bakken Pipeline system.

Environmental Proceedings

As described in our Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 10-K”), governmental and other entities in California, 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. In March 2020, the City and County of Honolulu, Hawaii filed suit against 20 oil and gas defendants, including MPC, making similar allegations. Similar lawsuits may be filed in other jurisdictions. At this early stage, the ultimate outcome of these matters remain uncertain, and neither the likelihood of an unfavorable outcome nor the ultimate liability, if any, can be determined.

Logistics and Storage

On April 10, 2020, we received a Notice of Probable Violation and Proposed Civil Penalty from the Pipeline and Hazardous Materials Safety Administration’s Office of Pipeline Safety (OPS) for alleged violations arising from the release at the Hospah Station pump station in New Mexico on September 7, 2018. The NOPV alleged a failure to follow written procedures for responding to, investigating, and correcting the cause of an increase in pressure of flow rate outside its normal operating limits, and a failure to follow appropriate procedures regarding related personnel performance. This matter was resolved for a cash penalty of approximately $236,000.

Detroit Refinery

As previously disclosed in our 2019 10-K, in June 2019, we received an offer from the Michigan Department of Environment, Great Lakes, and Energy to settle violations alleged in five NOVs issued to the refinery between September 2017 and February 2019. In December 2019, the settlement discussions were expanded to include two additional NOVs issued to the refinery during October and December 2019. The NOVs allege violations of emissions limitations and other requirements of the refinery’s air permit and Michigan air pollution control laws. We have agreed to settle this matter for a cash penalty under $100,000 and a supplemental environmental project with an expected approximate value of $282,000.

Galveston Bay Refinery

As previously disclosed on our 2019 10-K, in August 2019, we received an offer from the Texas Commission on Environmental Quality to settle violations alleged in enforcement notices issued to the refinery in March 2019. The notices allege violations of emissions limitations and other requirements of the refinery’s air permit. We have agreed to settle this matter for a cash penalty and a supplemental environmental project with a total combined value of under $100,000.

ITEM 1A. RISK FACTORS

Except as described below, 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.

Our working capital, cash flows and liquidity can be significantly affected by decreases in commodity prices.

Payment terms for our crude oil purchases are generally longer than the terms we extend to our customers for refined product sales. As a result, the payables for our crude oil purchases are proportionally larger than the receivables for our refined product sales. Due to this net payables position, a decrease in commodity prices generally results in a use of working capital, and given the significant volume of crude oil that we purchase the impact can materially affect our working capital, cash flows and liquidity.

The recent outbreak of COVID-19 and certain developments in the global oil markets have had, and may continue to have, material adverse consequences for general economic, financial and business conditions, and could materially and adversely affect our business, financial condition, results of operations and cash flows and those of our customers, suppliers and other counterparties.

The recent outbreak of COVID-19 and the responses of governmental authorities and companies and the self-imposed restrictions by many individuals across the world to stem the spread of the virus have significantly reduced global economic activity, as there has been a dramatic decrease in the number of businesses open for operation and substantially fewer people across the world traveling to work or leaving their home to purchase goods and services. This has also resulted, for example, in a dramatic reduction in airline flights and has reduced the number of cars on the road. As a result, there has been a decline in the demand for the refined petroleum products that we manufacture and sell.

Concerns over the negative effects of COVID-19 on economic and business prospects across the world have contributed to increased market and oil price volatility and have diminished expectations for the global economy. These factors, coupled with the emergence of decreasing business and consumer confidence and increasing unemployment resulting from the COVID-19 outbreak and the recent abrupt oil price decline, may precipitate a prolonged economic slowdown and recession. Our refinery utilization and operating margins and other aspects of our business have been adversely impacted by these developments. Any such prolonged period of economic slowdown or recession, or a protracted period of depressed prices for our products or crude oil or reduced margins for the refined petroleum products we manufacture and sell could have significant adverse consequences for our financial condition and the financial condition of our customers, suppliers and other counterparties, and could diminish our liquidity and negatively affect our ability to obtain adequate crude oil volumes and to market certain of our products at favorable prices, or at all.

Due to declines in the market prices of products held in our inventories, we recorded a material inventory valuation charge to cost of revenues to value certain of our inventories at the lower of cost or market. Depending on future movements of refined product prices, future inventory valuation adjustments could have a negative or positive effect on our financial performance. In addition, a sustained period of low crude oil prices may also result in significant financial constraints on certain producers from which we acquire our crude oil, which could result in long term crude oil supply constraints for our business. Such conditions could also result in an increased risk that our customers and other counterparties may be unable to fully fulfill their obligations in a timely manner, or at all. Any of the foregoing events or conditions, or other unforeseen consequences of COVID-19, could significantly adversely affect our business and financial condition and the business and financial condition of our customers and other counterparties.

The ultimate extent of the impact of COVID-19 on our business, financial condition, results of operations and cash flows will depend largely on future developments, including the duration and spread of the outbreak, particularly within the geographic areas where we operate, the related impact on overall economic activity and the timing of the lifting of restrictions and return of customer confidence, all of which are uncertain and cannot be predicted with certainty at this time.

The Court of Chancery of the State of Delaware will be, to the extent permitted by law, the sole and exclusive forum for substantially all disputes between us and our shareholders.

Our Restated Certificate of Incorporation provides that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for:


•	any derivative action or proceeding brought on behalf of MPC;


•	any action asserting a claim of breach of a fiduciary duty owed by any director or officer of MPC to MPC or its stockholders

Table of Contents


•	any action asserting a claim against MPC arising pursuant to any provision of the General Corporation Law of the State of Delaware, MPC’s Restated Certificate of Incorporation, any Preferred Stock Designation or the Bylaws of MPC; or


•	any other action asserting a claim against MPC or any Director or officer of MPC that is governed by or subject to the internal affairs doctrine for choice of law purposes.

The forum selection provision may restrict a stockholder’s ability to bring a claim against us or directors or officers of MPC in a forum that it finds favorable, which may discourage stockholders from bringing such claims at all. Alternatively, if a court were to find the forum selection provision contained in our Restated Certificate of Incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in another forum, which could materially adversely affect our business, financial condition and results of operations. However, the forum selection provision does not apply to any claims, actions or proceedings arising under the Securities Act or the Exchange Act.

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 March 31, 2020, of equity securities that are registered by MPC pursuant to Section 12 of the Securities Exchange Act of 1934, as amended.
