NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
1. DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION
Description of the Business
We are a leading, integrated, downstream energy company headquartered in Findlay, Ohio. We operate the nation's largest refining system. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to consumers through our Retail business segment and to independent entrepreneurs who operate approximately 7,000 branded outlets. Our retail operations own and operate approximately 3,870 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.
See Note 23 Subsequent Events for information regarding the announced agreement to sell our Speedway business.
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 and six months ended June 30, 2020 are not necessarily indicative of the results to be expected for the full year.
2. ACCOUNTING STANDARDS
Recently Adopted
Effective January 1, 2020, we adopted ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” using the modified retrospective transition method. The amendment requires entities 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 June 30, 2020, we reported $4,361 million of accounts and notes receivable, net of allowances of $18 million.
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 ASUs during the first six months of 2020, which also did not have a material impact to our financial statements or financial statement disclosures:

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 June 30, 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.
Noncontrolling Interest
As a result of equity transactions of MPLX and ANDX, we are required to adjust non-controlling interest and additional paid-in capital. Changes in MPC’s additional paid-in capital resulting from changes in its ownership interests in MPLX and ANDX were as follows:

4. IMPAIRMENTS
The outbreak of COVID-19 and its development into a pandemic in March 2020 have resulted in significant economic disruption globally. Actions taken by various governmental authorities, individuals and companies around the world to prevent the spread of COVID-19 through social distancing have restricted travel, many business operations, public gatherings and the overall level of individual movement and in-person interaction across the globe. This has in turn significantly reduced global economic activity and resulted in a decrease in motor vehicle use at a time when seasonal driving patterns typically result in an increase of consumer demand for gasoline and a dramatic reduction in airline flights. These macroeconomic conditions and certain global geopolitical events in the first quarter of 2020 contributed to a significant decline in crude oil prices as well as an increase in crude oil price volatility. The decrease in demand for refined petroleum products coupled with the decline in the price of crude oil has resulted in a significant decrease in the price and volume of the refined petroleum products we produce and sell as compared to the three and six months ended June 30, 2019.
During the first quarter of 2020, the overall deterioration in the economy and the environment in which we operate, the related changes to our expected future cash flows, as well as a sustained decrease in share price were considered triggering events requiring various impairment assessments of the carrying values of our assets, which resulted in the impairment charges discussed below.
The table below provides information related to the impairments recognized during the three and six months ended June 30, 2020 and the location of these impairments within the consolidated statements of income.

(a) 
Impairment expense in the three months ended June 30, 2020 is related to a Midstream terminal asset with remaining net book value of $10 million.
Goodwill
During the first quarter of 2020, we recorded an impairment of goodwill of $7.33 billion. See the table below for detail by segment. The goodwill impairment within the Refining & Marketing segment was primarily driven by the effects of COVID-19 and the decline in commodity prices. The impairment within the Midstream segment was primarily driven by additional information related to the slowing of drilling activity, which has reduced production growth forecasts from MPLX’s producer customers.
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:

Equity Method Investments
During the first quarter of 2020, we recorded equity method investment impairment charges totaling $1.315 billion, of which $1.25 billion related to MarkWest Utica EMG, L.L.C. and its investment in Ohio Gathering Company, L.L.C. The impairments were largely due to a reduction in forecasted volumes gathered and processed by the systems operated by the joint ventures. The fair value of the investments was determined based upon applying the discounted cash flow method, which is an income approach. The discounted cash flow fair value estimate is based on known or knowable information at the interim measurement date. The significant assumptions that were used to develop the estimate of the fair value under the discounted cash flow method include management’s best estimates of the expected future cash flows, including prices and volumes, the weighted average cost of capital and the long-term growth rate. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the impairment test will prove to be an accurate prediction of the future. The fair value of these equity method investments represents a Level 3 measurement.
Long-lived Assets
Long-lived assets used in operations are assessed for impairment whenever changes in facts and circumstances indicate that the carrying value of the assets may not be recoverable based on the expected undiscounted future cash flow of an asset group. For purposes of impairment evaluation, long-lived assets must be grouped at the lowest level for which independent cash flows can be identified, which generally is the refinery and associated distribution system level for Refining & Marketing segment assets, 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 within the Refining & Marketing segment as a result of decreases to the Refining & Marketing segment expected future cash flows. The cash flows associated with these assets were significantly impacted by the effects of COVID-19 and commodity price declines. We assessed each refinery asset group for impairment by comparing the undiscounted estimated pretax cash flows to the carrying value of each asset group. Of the 16 refinery asset groups, only the Gallup refinery’s carrying value exceeded its undiscounted estimated pretax cash flows. It was determined that the fair value of the Gallup refinery’s property, plant and equipment was less than the carrying value. As a result, we recorded a charge of $142 million in the first quarter of 2020 to impairment expense on the consolidated statements of income. The fair value measurements for the Gallup refinery assets represent Level 3 measurements.
During the second quarter of 2020, we identified long-lived asset impairment triggers relating to all of our refinery asset groups within the Refining & Marketing segment, except the Gallup refinery which had been impaired in the first quarter, as a result of continued macroeconomic developments impacting the Refining & Marketing segment expected future cash flows. All of these refinery asset group’s undiscounted estimated pretax cash flows exceeded their carrying value by at least 17 percent. The determination of undiscounted estimated pretax cash flows utilized significant assumptions including management’s best estimates of the expected future cash flows, allocation of certain Refining & Marketing segment cash flows to the individual refineries, the estimated useful lives of the asset groups, and the salvage values of the refineries. On August 3, 2020, we announced our plans to evaluate possibilities to strategically reposition our Martinez refinery, including the potential conversion of the refinery into a renewable diesel facility. The outcome of our evaluation could result in an impairment triggering event and significantly change the assumptions and results of a future impairment test for the refinery’s long-lived assets.
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 certain of our refinery asset groups exceed the undiscounted estimated pretax cash flows of their refinery asset groups, which would result in future impairment charges.
During the first quarter of 2020, we identified an impairment trigger relating to asset groups within MPLX’s Western G&P reporting unit as a result of significant changes to expected future cash flows for these asset groups resulting from the effects of COVID-19. The cash flows associated with these assets were significantly impacted by volume declines reflecting decreased forecasted producer customer production as a result of lower commodity prices. We assessed each asset group within the Western G&P reporting unit for impairment. It was determined that the fair value of the East Texas G&P asset group’s underlying assets were less than the carrying value. As a result, MPLX recorded impairment charges totaling $350 million related to its property, plant and equipment and intangibles, which are included in impairment expense on our consolidated statements of income. Fair value of property, plant and equipment was determined using a combination of an income and cost

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

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

8. EQUITY
As of June 30, 2020, we had $2.96 billion of remaining share repurchase authorizations from our board of directors. We may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block transactions, tender offers, accelerated share repurchases or open market solicitations for shares, some of which may be effected through Rule 10b5-1 plans. The timing and amount of future repurchases, if any, will depend upon several factors, including market and business conditions, and such repurchases may be 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 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 year to date interim period. For 2020, we continue to utilize this approach.
On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted 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:
Revising the limitations on the deductibility of interest from 30 percent of adjusted taxable income to 50 percent.
Ability to carry back tax net operating losses ("NOL") five years for NOLs arising in taxable years 2018 through 2020. This provision allows the taxpayer to recover taxes previously paid at a 35 percent federal income tax rate during years prior to 2018. The limitation on the percentage of taxable income that may be offset by the NOL, formerly 80 percent of income, was eliminated for years beginning before 2021.
We recorded an overall income tax benefit of $1.6 billion for the six months ended June 30, 2020, of which $309 million was attributable to the tax rate differential in the carryback years resulting from the expected NOL carryback provided under the CARES Act. As of June 30, 2020, the estimated cash tax refund resulting from the NOL carryback provided in the CARES Act is $1.1 billion and arises solely due to taxes paid in prior years. Absent the CARES Act, we would have recorded a deferred tax asset for the expected NOL carryforward under the currently effective federal income tax rate. For the three months ended June 30, 2020, we recorded income tax expense of $360 million, which reflects a change in our estimated annual effective tax rate and CARES Act benefit.
The combined federal, state and foreign income tax rate was 14 percent for the six months ended June 30, 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 the tax rate differential resulting from the expected NOL carryback provided under the CARES Act. Additionally, our effective tax rate is generally benefited by our noncontrolling interest in MPLX, but this benefit was lower for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 due to impairment charges recorded by MPLX.
The combined federal, state and foreign income tax rate was 57 percent for the three months ended June 30, 2020. The effective tax rate for the three months ended June 30, 2020 was higher than the U.S. statutory rate of 21 percent as well as higher than the effective rate for the three months ended June 30, 2019 primarily due the tax rate differential resulting from the expected NOL carryback provided under the CARES Act, permanent differences related to net income attributable to noncontrolling interests and changes in our estimated annual effective rate applied to income for the year to date interim period.
Based on the estimated NOL carryback, as provided by the CARES Act, we recorded an income tax receivable of $1.1 billion in other noncurrent assets to reflect our estimate of the tax refund we expect to realize at the time of our 2020 tax return filing, which is expected during the second half of 2021. 
A reconciliation of the tax provision (benefit) in dollars as determined using the federal statutory income tax rate applied to income (loss) before income taxes to the (benefit) provision for income taxes is shown in the table below.

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

We are continuously undergoing examination of our income tax returns, which have been completed through the 2005 tax year for state returns and the 2010 tax year for our U.S. federal return. As of June 30, 2020, we had $25 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.

Inventories are carried at the lower of cost or market value. Costs of crude oil and refined products are aggregated on a consolidated basis for purposes of assessing whether the LIFO cost basis of these inventories may have to be written down to market values. At June 30, 2020, market values for these inventories were lower than their LIFO cost basis, resulting in a reserve of $1.74 billion. The reduction from the $3.22 billion LCM inventory valuation reserve at March 31, 2020 resulted in a benefit of $1.48 billion for the three months ended June 30, 2020.
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 six months ended June 30, 2020.
13. EQUITY METHOD INVESTMENTS
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.
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.

(a) 
Represents the impact of netting assets, liabilities and cash collateral when a legal right of offset exists. As of June 30, 2020, cash collateral of $98 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.

Table of Contents
                            

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 June 30, 2020 used significant unobservable inputs including: (1) NGL prices interpolated and extrapolated due to inactive markets ranging from $0.38 to $0.92 per gallon with a weighted average of $0.53 per gallon per the current term of the embedded derivative and (2) the probability of renewal of 100 percent for the first five-year term and 100 percent for the second five-year term of the natural gas purchase agreement and the related keep-whole processing agreement. Increases or decreases in the fractionation spread result in an increase or decrease in the fair value of the embedded derivative liability. An increase in the probability of renewal would result in an increase in the fair value of the related embedded derivative liability.
The following is a reconciliation of the beginning and ending balances recorded for net liabilities classified as Level 3 in the fair value hierarchy.

Fair Values – Reported
We believe the carrying value of our other financial instruments, including cash and cash equivalents, receivables, accounts payable and certain accrued liabilities, approximate fair value. Our fair value assessment incorporates a variety of considerations, including the short-term duration of the instruments and the expected insignificance of bad debt expense, which includes an evaluation of counterparty credit risk. The borrowings under our revolving credit facilities and term loan facility, which include variable interest rates, approximate fair value. The fair value of our fixed and floating rate long-term debt is based on prices from recent trade activity and is categorized in level 3 of the fair value hierarchy. The carrying and fair values of our debt were approximately $31.6 billion and $33.6 billion at June 30, 2020, respectively, and approximately $28.3 billion and $30.1 billion at December 31, 2019, respectively. These carrying and fair values of our debt exclude the unamortized issuance costs which are netted against our total debt.
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 June 30, 2020 and December 31, 2019 and the line items in the balance sheets in which the fair values are reflected. The fair value amounts below are presented on a gross basis and do not reflect the netting of asset and liability positions permitted under the terms of our master netting arrangements including cash collateral on deposit with, or received from, brokers. We offset the recognized fair value amounts for multiple derivative instruments executed with the same counterparty in our financial statements when a legal right of offset exists. As a result, the asset and liability amounts below will not agree with the amounts presented in our consolidated balance sheets.

Borrowed $2.5 billion at an average interest rate of 1.53 percent and repaid $1.675 billion during the six months ended June 30, 2020.
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 billion five-year revolving credit facility and $1 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 certain amounts outstanding under its five-year revolving credit facility.

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.
At June 30, 2020 and December 31, 2019, accrued liabilities for remediation totaled $412 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 $28 million and $29 million at June 30, 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 Legal Proceedings
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. On June 1, 2020, the trial court granted our motion for summary judgment and dismissed all federal law claims with prejudice. State-based claims were dismissed without prejudice.
In early July 2020, MPLX received a Notification of Trespass Determination from the Bureau of Indian Affairs (“BIA”) relating to a portion of the Tesoro High Plains Pipeline that crosses the Fort Berthold Reservation in North Dakota. The notification covers the rights of way for 23 tracts of land and demands the immediate cessation of pipeline operations. The notification also assesses trespass damages of approximately $187 million. MPLX expects to receive a notification for an additional 11 tracts in the near future. MPLX appealed this determination, which triggered an automatic stay of the requested pipeline shutdown and payment. We believe the trespass damage calculation is dependent on a novel interpretation of the applicable law, and MPLX continues to actively negotiate settlement of this matter with holders of the property rights at issue. Management does not believe the ultimate resolution of this matter will have a material adverse effect on our consolidated financial position, results of operations, or cash flows.
We are also a party to a number of other lawsuits and other proceedings arising in the ordinary course of business. While the ultimate outcome and impact to us cannot be predicted with certainty, we believe that the resolution of these other lawsuits and proceedings will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.
Guarantees
We have provided certain guarantees, direct and indirect, of the indebtedness of other companies. Under the terms of most of these guarantee arrangements, we would be required to perform should the guaranteed party fail to fulfill its obligations under the specified arrangements. In addition to these financial guarantees, we also have various performance guarantees related to specific agreements.

27

Table of Contents
                            

Guarantees related to indebtedness of equity method investees
LOOP and LOCAP
MPC and MPLX hold interests in an offshore oil port, LOOP, and MPLX holds an interest in a crude oil pipeline system, LOCAP. Both LOOP and LOCAP have secured various project financings with throughput and deficiency agreements. Under the agreements, MPC, as a shipper, is required to advance funds if the investees are unable to service their debt. Any such advances are considered prepayments of future transportation charges. The duration of the agreements varies but tends to 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 June 30, 2020.
Gray Oak Pipeline, LLC
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 Pipeline 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 June 30, 2020, our maximum potential undiscounted payments under the Equity Contribution Agreement for the debt principal totaled $345 million.
Dakota Access Pipeline
In connection with MPLX’s 9.19 percent indirect interest in a joint venture (“Dakota Access”) that owns and operates the Dakota Access Pipeline and Energy Transfer Crude Oil Pipeline projects, collectively referred to as the Bakken Pipeline system, MPLX has entered into a Contingent Equity Contribution Agreement. MPLX, along with the other joint venture owners in the Bakken Pipeline system, 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 (the “D.D.C.”) ordered the U.S. Army Corps of Engineers (“Army Corps”), 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.
On July 6, 2020, the D.D.C. ordered vacatur of the easement permit during the pendency of an EIS and further ordered a shut down of the pipeline by August 5, 2020. The D.D.C. denied a motion to stay that order. Dakota Access and the Army Corps are appealing the D.D.C.’s orders to the U.S. Court of Appeals for the District of Columbia Circuit. On July 14, 2020, the Circuit Court issued an administrative stay while the court considers Dakota Access and the Army Corps’ emergency motion for stay pending appeal.
If the pipeline is temporarily shut down pending completion of the EIS, MPLX would have to contribute its 9.19 percent pro rata share of funds required to pay interest accruing on the notes and any portion of the principal that matures while the pipeline is shutdown. It is expected that MPLX would contribute its 9.19 percent pro rata share of any costs to remediate any deficiencies to reinstate the permit and/or return the pipeline into operation. If the vacatur of the easement permit results in a permanent shutdown of the pipeline, MPLX would have to contribute its 9.19 percent pro rata share of the cost to redeem the bonds (including the one percent redemption premium required pursuant to the indenture governing the notes) and any accrued and unpaid interest. As of June 30, 2020, our maximum potential undiscounted payments under the Contingent Equity Contribution Agreement was approximately $230 million.
Crowley Ocean Partners LLC and Crowley Blue Water Partners LLC
In connection with our 50 percent indirect interest in Crowley Ocean Partners LLC, we have agreed to conditionally guarantee our portion of the obligations of the joint venture and its subsidiaries under a senior secured term loan agreement. The term loan agreement provides for loans of up to $325 million to finance the acquisition of four product tankers. MPC’s liability under the guarantee for each vessel is conditioned upon the occurrence of certain events, including if we cease to maintain an investment grade credit rating or the charter for the relevant product tanker ceases to be in effect and is not replaced by a

28

Table of Contents
                            

charter with an investment grade company on certain defined commercial terms. As of June 30, 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 June 30, 2020, our maximum potential undiscounted payments under this arrangement was $118 million.
Marathon Oil indemnificationsThe 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 $104 million as of June 30, 2020, which primarily consist of a commitment to contribute cash to an equity method investee for certain catastrophic events, in lieu of procuring insurance coverage, a commitment to fund a share of the bonds issued by a government entity for construction of public utilities in the event that other industrial users of the facility default on their utility payments and leases of assets containing general lease indemnities and guaranteed residual values.
General guarantees associated with dispositions—Over the years, we have sold various assets in the normal course of our business. Certain of the related agreements contain performance and general guarantees, including guarantees regarding inaccuracies in representations, warranties, covenants and agreements, and environmental and general indemnifications that require us to perform upon the occurrence of a triggering event or condition. These guarantees and indemnifications are part of the normal course of selling assets. We are typically not able to calculate the maximum potential amount of future payments that could be made under such contractual provisions because of the variability inherent in the guarantees and indemnities. Most often, the nature of the guarantees and indemnities is such that there is no appropriate method for quantifying the exposure because the underlying triggering event has little or no past experience upon which a reasonable prediction of the outcome can be based.
Contractual Commitments and Contingencies
At June 30, 2020, our contractual commitments to acquire property, plant and equipment and advance funds to equity method investees totaled $678 million.
Certain natural gas processing and gathering arrangements require us to construct natural gas processing plants, natural gas gathering pipelines and NGL pipelines and contain certain fees and charges if specified construction milestones are not achieved for reasons other than force majeure. In certain cases, certain producer customers may have the right to cancel the processing arrangements with us if there are significant delays that are not due to force majeure.
23. SUBSEQUENT EVENTS
Agreement to sell our Speedway business
On August 2, 2020, we entered into a definitive agreement to sell Speedway, our company-owned and operated retail transportation fuel and convenience store business, to 7-Eleven, Inc. for $21 billion in cash. The taxable transaction is expected to close in the first quarter of 2021, subject to customary closing conditions and regulatory approvals. The Speedway business is currently a reporting unit within our Retail segment. Our Retail segment also includes the results of our direct dealer business, which we will retain after the closing of this transaction. In connection with the signing of this agreement, we expect to account for the Speedway business as Assets Held for Sale starting in the third quarter of 2020. As a result, the prospective and historical results of the Speedway business will be presented as discontinued operations in our consolidated financial statements.
Redemption of business from MPLX
On July 31, 2020, Western Refining Southwest, Inc. (“WRSW”), a wholly owned subsidiary of MPC, entered into a Redemption Agreement (the “Redemption Agreement”) with MPLX, pursuant to which MPLX agreed to transfer to WRSW, all of the outstanding membership interests in Western Refining Wholesale, LLC, (“WRW”) in exchange for the redemption of MPLX common units held by WRSW. The transactions effects the transfer to MPC of the Western wholesale distribution business that MPLX acquired as a result of its acquisition of ANDX. The results of these operations will be presented in MPC’s Refining & Marketing segment prospectively.

At the Closing, per the terms of Redemption Agreement, MPLX redeemed 18,582,088 Common Units (the “Redeemed Units”) held by WRSW The number of Redeemed Units was calculated by dividing WRW’s aggregate valuation of $340 million by the simple average of the volume weighted average New York Stock Exchange prices of an MPLX Common Unit for the ten trading days ending at market close on July 27, 2020. The transaction will result in a minor decrease in MPC’s beneficial ownership interest in MPLX.

CORPORATE OVERVIEW
We are an independent petroleum refining and marketing, retail and midstream company. We own and operate the nation’s largest refining system. Our refineries supply refined products to resellers and consumers across the United States. We distribute refined products to our customers through transportation, storage, distribution and marketing services provided largely by our Midstream segment. We believe we are one of the largest wholesale suppliers of gasoline and distillates to resellers in the United States.
We have three strong brands: Marathon®, Speedway® and ARCO®. The branded outlets, which primarily operate under the Marathon brand, are established motor fuel brands across the United States available through approximately 7,000 branded outlets operated by independent entrepreneurs in 35 states, the District of Columbia and Mexico. 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 3,870 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 June 30, 2020, we owned, leased or had ownership interests in approximately 17,200 miles of crude oil and

32

Table of Contents
                            

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 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.
Refining & Marketing – refines crude oil and other feedstocks at our refineries in the Gulf Coast, Mid-Continent and West Coast regions of the United States, purchases refined products and ethanol for resale and distributes refined products through transportation, storage, distribution and marketing services provided largely by our Midstream segment. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to 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.
Recent Developments
Business Update
The outbreak of COVID-19 and its development into a pandemic in March 2020 have resulted in significant economic disruption globally. Actions taken by various governmental authorities, individuals and companies around the world to prevent the spread of COVID-19 through social distancing have restricted travel, many business operations, public gatherings and the overall level of individual movement and in-person interaction across the globe.
This has in turn significantly reduced global economic activity and resulted in a decrease in motor vehicle use at a time when seasonal driving patterns typically result in an increase of consumer demand for gasoline and a dramatic reduction in airline flights. As a result, there has also been a decline in the demand for the refined petroleum products that we manufacture and sell.
During the first quarter of 2020, COVID-19 macroeconomic conditions and certain global geopolitical events contributed to a decline in crude oil prices. Since the decline of crude oil prices during the first quarter of 2020, crude oil price volatility has increased.
The price of refined products we sell and the feedstocks we purchase impact our revenues, income from operations, net income and cash flows. 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 and volume of the refined petroleum products we produce and sell and had a negative impact on working capital during the first six months of 2020.
In addition, a decline in the market prices for products held in our inventories below the carrying value of our inventory resulted in an adjustment to the value of our inventories. At June 30, 2020 and March 31, 2020, market values for these inventories were lower than their LIFO cost basis and, as a result, we recorded an LCM inventory valuation reserve of $1.74 billion and $3.22 billion, respectively. The decrease in the LCM reserve resulted in an LCM benefit of $1.48 billion for the three months ended June 30, 2020, which reflects the partial recovery of market prices of refined products during the second quarter. Based on movements of refined product prices, future inventory valuation adjustments could have a negative or positive effect to earnings. Such losses are subject to reversal in subsequent periods if prices recover.
We have been and continue actively responding to the impacts that these matters are having on our business. Beginning in March 2020, we reduced 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. On August 3, in order to strengthen the competitive position of our assets and in response to continued decreased demand for our products, we announced our decision to indefinitely idle our Gallup and Martinez refineries and our plans to evaluate possibilities to strategically reposition our Martinez refinery, including the potential conversion of the refinery into a renewable diesel facility. In addition to these measures to address our operations, we took action to address our liquidity as outlined below.

33

Table of Contents
                            

We expect to defer or delay certain capital expenditures of approximately $1.35 billion, resulting in planned 2020 capital spending of $3.0 billion, a reduction of approximately 30 percent from our initial plan for the year. 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.
We have taken and continue to take actions to reduce 2020 forecasted operating expenses by approximately $950 million, primarily through reductions of fixed costs and deferral of certain expense projects, which includes $200 million of operating expense reductions at MPLX.
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 certain amounts outstanding on the five-year revolving credit facility.
During June 2020, we repaid the remaining amounts outstanding on the five-year revolving credit facility. At June 30, 2020, we had $7.7 billion available on our variable credit facilities.
Many uncertainties remain with respect to COVID-19, including its resulting economic effects, and we are unable to predict the ultimate economic impacts from COVID-19 and how quickly national economies can recover once the pandemic ultimately subsides. However, the adverse impact of the economic effects on MPC has been and will likely continue to be significant. We believe we have proactively addressed many of the known impacts of COVID-19 to the extent possible and will strive to continue to do so, but there can be no guarantee the measures will be fully effective.
Strategic Actions to Enhance Shareholder Value
On August 2, 2020, we entered into a definitive agreement to sell Speedway, our company-owned and operated retail transportation fuel and convenience store business, to 7-Eleven, Inc. for $21 billion in cash. The sale is expected to result in after-tax proceeds of approximately $16.5 billion, which are expected to be used to both repay debt to protect our investment grade credit profile and fund return of capital to our shareholders. We had previously announced our intention to separate Speedway into an independent, publicly traded company through a tax-free distribution to our shareholders. This all cash transaction represents a significant unlocking of value and immediately captures the value of the Speedway business for MPC shareholders relative to potential valuation risks of other alternatives. The arrangement includes a 15-year fuel supply agreement for approximately 7.7 billion gallons per year associated with the Speedway business. Further, the company expects incremental opportunities over time to supply 7-Eleven’s remaining business as existing arrangements mature and as 7-Eleven adds new locations in connection with its announced U.S. and Canada growth strategy.
The taxable transaction is expected to close in the first quarter of 2021, subject to customary closing conditions and regulatory approvals. In connection with the signing of this agreement, we expect to account for the Speedway business as Assets Held for Sale starting in the third quarter of 2020. As a result, the prospective and historical results of the Speedway business will be presented as discontinued operations in our consolidated financial statements.
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.
Other
On July 31, 2020, Western Refining Southwest, Inc. (“WRSW”), a wholly owned subsidiary of MPC, entered into a Redemption Agreement (the “Redemption Agreement”) with MPLX, pursuant to which MPLX agreed to transfer to WRSW all of the outstanding membership interests in Western Refining Wholesale, LLC (“WRW”), in exchange for the redemption of MPLX common units valued at $340 million held by WRSW. The transaction will result in a minor decrease in MPC’s beneficial ownership interest in MPLX and the results of these operations will be presented in the Refining & Marketing segment prospectively.

Actions taken by various governmental authorities, individuals and companies to prevent the spread of COVID-19 through social distancing have restricted travel, many business operations, public gatherings and the overall level of individual movement and in-person interaction in the areas where we operate which has impacted demand for our products. Net income (loss) attributable to MPC was $9 million, or $0.01 per diluted share, in the second quarter of 2020 compared to $1.11 billion, or $1.66 per diluted share, for the second quarter of 2019 and $(9.23) billion, or $(14.21) per diluted share, in the first six months of 2020 compared to $1.10 billion, or $1.63 per diluted share, in the first six months of 2019.
For the second quarter of 2020, the change was largely due to a decrease in refined product sales volumes and prices, primarily driven by the effects of COVID-19 and the decline in commodity prices, partially offset by a $1.48 billion LCM benefit recognized in the quarter.
For the first six months of 2020, the change was primarily due to a loss in our Refining & Marketing segment, goodwill and long-lived asset impairment charges of $7.85 billion, an LCM charge of $1.74 billion and impairments of equity method investments of $1.32 billion during the period primarily driven by the effects of COVID-19 and the decline in commodity prices. The loss from operations in our Refining & Marketing segment due to decreases in refined product sales volumes and prices during the current period was partially offset by increased income from operations in our Retail segment mainly due to higher fuel margins.
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 six 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 second quarter of 2020 as compared to the second quarter of 2019 and the first six months of 2020 compared to the first six months of 2019.

MPLX
We owned approximately 666 million MPLX common units at June 30, 2020 with a market value of $11.51 billion based on the June 30, 2020 closing price of $17.28 per common unit. On July 28, 2020, MPLX declared a quarterly cash distribution of $0.6875 per common unit payable on August 14, 2020. As a result, MPLX will make distributions totaling $715 million to its common unitholders. MPC’s portion of these distributions is approximately $445 million.
We received limited partner distributions of $904 million from MPLX in the six months ended June 30, 2020 and $953 million from MPLX and ANDX combined in the six months ended June 30, 2019. The decrease in distributions from the prior year is due to the fact that ANDX had a higher per unit distribution prior to the Merger when compared to the MPLX distribution per unit post-merger.
See Note 3 to the unaudited consolidated financial statements for additional information on MPLX.
Share Repurchases
During the six months ended June 30, 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 June 30, 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
Late in the first quarter and early in the second quarter of 2020, MPC borrowed a total of $3.5 billion under its five-year revolving credit facility to provide financial flexibility given the commodity price downturn and the significant working capital impact associated with the decline in crude oil 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. In late April, the company issued $2.5 billion of senior notes, the proceeds of which were used to repay certain amounts outstanding on the five-year revolving credit facility, and entered into a credit agreement with a syndicate of lenders providing for an additional $1 billion 364-day revolving credit facility. In June, the company repaid the remaining amounts outstanding on the five-year revolving credit facility. As of June 30, 2020, we had cash and cash equivalents of approximately $1.02 billion, excluding MPLX cash and cash equivalents of $67 million, $5.0 billion available under a five-year bank revolving credit facility, $2.0 billion available under two 364-day bank revolving credit facilities and $705 million available under our trade receivables securitization facility resulting in total cash and available capacity on our credit facilities of $8.73 billion.
MPLX’s liquidity totaled $4.24 billion at June 30, 2020. As of June 30, 2020, MPLX had cash and cash equivalents of $67 million, $2.68 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.

Table of Contents
                            

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.

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.
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

37

Table of Contents
                            

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.

The first six months of 2020 includes $1.32 billion of impairment expense. See Note 4 to the unaudited consolidated financial statements for further information.
Second Quarter 2020 Compared to Second Quarter 2019
Net income (loss) attributable to MPC decreased $1.10 billion in the second quarter of 2020 compared to the second quarter of 2019 largely due to a decrease in refined product sales volumes and prices, primarily driven by the effects of COVID-19 and the decline in commodity prices, partially offset by an LCM benefit of $1.48 billion recognized during the quarter.
Revenues and other income decreased $18.47 billion primarily due to:
decreased sales and other operating revenues of $18.51 billion primarily due to decreased Refining & Marketing segment refined product sales volumes, which decreased 936 mbpd, and decreased average refined product sales prices of $0.98 per gallon largely due to reduced travel and business operations associated with the COVID-19 pandemic; and
increased other income of $37 million mainly due to 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. Speedway recognizes its share of the diesel fuel margins as Other Income and no longer reports the revenue or costs and expenses related to sales at its locations since these are now conducted by PTC.

Table of Contents
                            

Costs and expenses decreased $17.41 billion primarily due to:
decreased cost of revenues of $15.91 billion mainly due to lower refined product sales volumes, which decreased 936 mbpd primarily due to reduced travel and business operations associated with the COVID-19 pandemic;
an LCM benefit of $1.48 billion resulting from a lower LCM reserve as of June 30, 2020 as compared to March 31, 2020;
decreased selling, general and administrative expenses of $140 million mainly due to decreases in salaries and employee-related expenses, credit card processing fees and litigation expense; and
increased other taxes of $40 million primarily due to increased property and environmental taxes of approximately $22 million and $18 million, respectively. Property taxes increased in the current period mainly due to the absence of property tax refunds and tax exemptions received in the second quarter of 2019 and environmental taxes increased largely due to the reinstatement of the Oil Spill Tax in 2020, which was not in effect for all of 2019.
Provision for income taxes was $360 million for the three months ended June 30, 2020 compared to $353 million for the three months ended June 30, 2019. The combined federal, state and foreign income tax rate was 57 percent for the three months ended June 30, 2020. The effective tax rate for the three months ended June 30, 2020 was higher than the U.S. statutory rate of 21 percent as well as higher than the effective rate for the three months ended June 30, 2019 primarily due to the tax rate differential resulting from the expected NOL carryback provided under the CARES Act, permanent differences related to net income attributable to noncontrolling interests and changes in our estimated annual effective rate applied to income for the year to date interim period. The combined federal, state and foreign income tax rate was 21 percent for the three months ended June 30, 2019. The effective tax rate for the three months ended June 30, 2019 was equal to the U.S. statutory rate primarily due to certain permanent tax differences related to net income attributable to noncontrolling interests offset by equity compensation and state and local tax expense.
Six Months Ended June 30, 2020 Compared to Six Months Ended June 30, 2019
Net income (loss) attributable to MPC decreased $10.32 billion in the first six months of 2020 compared to the first six months of 2019 primarily due to impairment expenses for goodwill and long-lived assets of $7.85 billion, an LCM charge of $1.74 billion, impairments of equity method investments of $1.32 billion during the period and a decrease in refined product sales volumes and prices.
Revenues and other income decreased $22.99 billion primarily due to:
decreased sales and other operating revenues of $21.54 billion primarily due to decreased Refining & Marketing segment refined product sales volumes, which decreased 509 mbpd, and decreased average refined product sales prices of $0.57 per gallon reduced 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;
decreased net gain on disposal of assets of $212 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; and
increased other income of $73 million mainly due to an agreement between Speedway and PTC, effective October 1, 2019, in which PTC supplies, prices and sells diesel fuel at certain Speedway and PTC locations with both companies sharing in the diesel fuel margins. Speedway recognizes its share of the diesel fuel margins as Other Income and no longer reports the revenue or costs and expenses related to sales at its locations since these are now conducted by PTC.
Costs and expenses decreased $9.45 billion primarily due to:
decreased cost of revenues of $19.04 billion primarily due to reduced travel and business operations associated with the COVID-19 pandemic;
an LCM charge of $1.74 billion primarily driven by the effects of COVID-19 and the decline in commodity prices;
impairment expense of $7.85 billion recorded for goodwill and long-lived assets of $7.33 billion and $517 million, respectively, primarily driven by the effects of COVID-19 and the decline in commodity prices;
decreased selling, general and administrative expenses of $186 million mainly due to decreases in transaction-related expenses, salaries and employee-related expenses and credit card processing fees; and
increased other taxes of $105 million primarily due to increased property and environmental taxes of approximately $56 million and $39 million, respectively. Property taxes increased in the current period mainly due to the absence of property tax refunds received in the first six months of 2019 and environmental taxes increased largely due to the reinstatement of the Oil Spill Tax in 2020, which was not in effect for all of 2019.

Net interest and other financial costs increased $55 million largely due to increased MPC and MPLX borrowings, foreign currency exchange losses and decreased interest income.
Benefit for income taxes was $1.58 billion for the six months ended June 30, 2020 compared to provision for income taxes of $457 million for the six months ended June 30, 2019, mainly due to decreased income before income taxes of $13.60 billion. The combined federal, state and foreign income tax rate was 14 percent and 22 percent for the six months ended June 30, 2020 and 2019, respectively. The effective tax rate for the six months ended June 30, 2020 was lower than the U.S. statutory rate of 21 percent primarily due to a significant amount of our pre-tax loss consisting of non-tax deductible goodwill impairment charges, partially offset by the tax rate differential resulting from the expected NOL carryback provided under the CARES Act. Additionally, our effective tax rate is generally benefited by our noncontrolling interest in MPLX, but this benefit was lower for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 due to impairment charges recorded by MPLX. The effective tax rate for the six months ended June 30, 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.
Net income attributable to noncontrolling interests decreased $1.24 billion primarily due to MPLX’s net loss primarily resulting from impairment expense recognized during the first six months of 2020.

Second Quarter 2020 Compared to Second Quarter 2019
Refining & Marketing segment revenues decreased $17.85 billion primarily due to lower refined product sales volumes, which decreased 936 mbpd, and decreased average refined product sales prices of $0.98 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 71 percent and net refinery throughputs decreased 859 mbpd during the second quarter of 2020, primarily due to reducing throughputs and temporarily idling certain facilities during the COVID-19 pandemic.
Refining & Marketing segment results from operations decreased $2.53 billion primarily due to lower blended crack spreads.
Refining & Marketing margin was $7.13 per barrel for the second quarter of 2020 compared to $15.24 per barrel for the second quarter of 2019. Refining & Marketing margin is affected by our performance against the market indicators shown earlier, which use spot market values and an estimated mix of crude purchases and product sales. Based on the market indicators and our crude oil throughput, we estimate a net negative impact of approximately $3.5 billion on Refining & Marketing margin for the second quarter of 2020 compared to the second quarter of 2019, primarily due to lower crack spreads. Our reported Refining & Marketing margin differs from market indicators due to the mix of crudes purchased and their costs, the effect of market structure on our crude oil acquisition prices, the effect of RIN prices on the crack spread, and other items like refinery yields and other feedstock variances. These factors had an estimated net positive effect of approximately $600 million on Refining & Marketing segment income in the second quarter of 2020 compared to the second quarter of 2019.

For the three months ended June 30, 2020, refining operating, distribution and turnaround costs, excluding depreciation, were $2.65 billion. This was a decrease of $395 million compared to the three months ended June 30, 2019 as we took actions to reduce costs in response to the economic effects of COVID-19, including operating at lower throughput at our refineries and idling portions of our refining capacity. Net refinery throughput was 859 mbpd lower as compared to the three months ended June 30, 2019. On a per barrel basis, refining operating costs, excluding depreciation and amortization, increased $0.78 and distribution costs, excluding depreciation and amortization, increased $1.38, primarily due to lower throughput partially offset by a decrease in costs. Distribution costs, excluding depreciation and amortization, include fees paid to MPLX of $841 million and $798 million for the second quarter of 2020 and 2019, respectively. Refining planned turnaround costs decreased $0.05 per barrel due to the timing of turnaround activity and lower throughput. Depreciation and amortization per barrel increased by $0.65 per barrel primarily due to lower throughput.
Six Months Ended June 30, 2020 Compared to Six Months Ended June 30, 2019
Refining & Marketing segment revenues decreased $21.04 billion primarily due to lower refined product sales volumes, which decreased 509 mbpd and decreased average refined product sales prices of $0.57 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 81 percent in the first six months of 2020 and total refinery throughputs decreased 474 mbpd, primarily due to reducing throughputs and temporarily idling certain facilities during the COVID-19 pandemic.
Refining & Marketing segment results from operations decreased $2.81 billion primarily driven by lower blended crack spreads.
Refining & Marketing margin was $9.50 per barrel for the first six months of 2020 compared to $13.23 per barrel for the first six months of 2019. Refining & Marketing margin is affected by the market indicators shown earlier, which use spot market values and an estimated mix of crude purchases and product sales. Based on the market indicators and our crude oil throughput, we estimate a net negative impact of approximately $4.0 billion on Refining & Marketing margin for the first six months of 2020 compared to the first six months of 2019, primarily due to lower crack spreads. Our reported Refining & Marketing margin differs from market indicators due to the mix of crudes purchased and their costs, market structure on our crude oil acquisition prices, RIN prices on the crack spread, and other items like refinery yields and other feedstock variances. These factors had an estimated net positive effect of approximately $1.2 billion on Refining & Marketing segment income in the first six months of 2020 compared to the first six months of 2019.

For the six months ended June 30, 2020, refining operating and distribution costs, excluding depreciation, were $5.41 billion. This was a decrease of $236 million compared to the six months ended June 30, 2019 as we took actions to reduce costs in response to the economic effects of COVID-19, including operating at lower throughput at our refineries and idling portions of our refining capacity. Net refinery throughput was 474 mbpd lower as compared to the six months ended June 30, 2019. These decreases were partially offset by increased refining planned turnaround costs of $68 million. On a per barrel basis, refining operating costs, excluding depreciation and amortization, increased $0.59 and distribution costs, excluding

43

depreciation and amortization, increased $0.66 mainly due to lower throughput partially offset by a decrease in costs. Distribution costs, excluding depreciation and amortization, include fees paid to MPLX of $1.70 billion and $1.58 billion for the for the first six months of 2020 and 2019, respectively. Refining planned turnaround costs increased $0.27 per barrel due to the timing of turnaround activity and a decrease in throughput. Depreciation and amortization per barrel increased by $0.34 primarily due to a decrease in throughput.

Second Quarter 2020 Compared to Second Quarter 2019
Retail segment revenues decreased $4.17 billion primarily due to decreased fuel sales and merchandise sales. Total fuel sales volumes decreased 944 million gallons and average fuel sales prices decreased $0.74 per gallon. Merchandise sales decreased $17 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. In addition, fuel sales volumes decreased as a result of an agreement between Speedway and PTC, effective October 1, 2019, in which PTC supplies, prices and sells diesel fuel at certain Speedway and PTC locations with both companies sharing in the diesel fuel margins. Speedway recognizes its share of the diesel fuel margins as Other Income and no longer reports the revenue or costs and expenses related to diesel sales at the Speedway locations that are now conducted by PTC.
Retail segment income from operations increased $1 million largely driven by an increase in retail fuel margins and a decrease in operating expenses offset by decreases in fuel volumes and merchandise margins. The retail fuel margin increased to 39.60 cents per gallon in the second quarter of 2020, from 26.66 cents per gallon in the second quarter of 2019.
Six Months Ended June 30, 2020 Compared to Six Months Ended June 30, 2019
Retail segment revenues decreased $4.77 billion primarily due to decreased fuel sales volumes of 1.22 billion gallons, partially offset by increased merchandise sales. Total fuel sales volumes decreased 1.22 billion gallons and average fuel sales price

decreased $0.42 per gallon. Merchandise sales increased $31 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 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. Speedway recognizes its share of the diesel fuel margins as Other Income and no longer reports the revenue or costs and expenses related to diesel sales at the Speedway locations that are now conducted by PTC.
Retail segment income from operations increased $350 million largely driven by higher fuel margins. The Retail fuel margin increased to 35.77 cents per gallon in the first six months of 2020 compared with 22.00 cents per gallon in the first six months of 2019 while the merchandise margin decreased $12 million.

Corporate costs consist primarily of MPC’s corporate administrative expenses and costs related to certain non-operating assets, except for corporate overhead expenses attributable to MPLX, which are included in the Midstream segment.
Second Quarter 2020 Compared to Second Quarter 2019
Corporate costs increased $9 million primarily due to an information systems integration project.
During the second quarter of 2020, we recognized an LCM benefit of $1.48 billion. The second quarter of 2020 also includes impairment charges of approximately $25 million related to long-lived assets.
Items not allocated to segments include transaction-related costs of $30 million for the second quarter of 2020 associated with the Speedway separation and other related activities and $34 million for the second quarter of 2019 largely related to employee retention, severance and other costs associated with the Andeavor acquisition. The second quarter of 2019 also includes a litigation reserve of $22 million.
Six Months Ended June 30, 2020 Compared to Six Months Ended June 30, 2019
Corporate costs increased $45 million primarily due to an information systems integration project.
During the first six months of 2020, we recorded impairment charges of approximately $9.16 billion, which includes $7.85 billion related to goodwill and long-lived assets and $1.32 billion related to equity method investments, and an LCM charge of $1.74 billion primarily driven by the effects of COVID-19 and the decline in commodity prices.
Items not allocated to segments also include transaction-related costs of $65 million for the first six months of 2020 associated with the Speedway separation, Midstream strategic review and other related activities and $125 million for the first six months of 2019 largely related to the recognition of an obligation for vacation benefits provided to former Andeavor employees as part of the Andeavor acquisition as well as employee retention, severance and other costs. In the first six months of 2019, other unallocated items include a $207 million gain resulting from the agreements executed with Capline LLC to contribute our 33 percent undivided interest in the Capline pipeline system in exchange for a 33 percent ownership interest in Capline LLC and a litigation reserve of $22 million.
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 $1.09 billion at June 30, 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.

(476

Net cash provided by operating activities decreased $4.48 billion in the first six months of 2020 compared to the first six months of 2019, primarily due to a decrease in operating results and an unfavorable change in working capital of $1.98 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 $1.66 billion use of cash in the first six months of 2020 compared to a net $322 million source of cash in the first six months of 2019.
For the first six months of 2020, changes in working capital, excluding the LCM reserve and changes in short-term debt, were a net $1.66 billion use of cash primarily due to the effects of decreasing energy commodity prices and volumes at the end of the period on working capital. Accounts payable decreased primarily due to decreases in crude prices and volumes. Current

receivables decreased primarily due to lower crude and refined product prices and volumes. Excluding the LCM reserve, inventories decreased due to decreases in crude and refined product inventories.
For the first six months of 2019, changes in working capital, excluding changes in short-term debt, were a net $322 million source of cash primarily due to the effects of increasing energy commodity prices at the end of the period on working capital. Current receivables increased primarily due to higher refined product and crude prices and higher crude sales volumes. Accounts payable increased primarily due to increases in crude prices and crude volumes. Inventories decreased due to decreases in refined product and crude inventories, partially offset by an increase in materials and supplies inventory.
Net cash used in investing activities decreased $803 million in the first six months of 2020 compared to the first six months of 2019, primarily due to the following:
a decrease in additions to property, plant and equipment of $509 million primarily due to decreased capital expenditures in the first six months of 2020 in our Midstream and Refining & Marketing segments; and
a decrease in net investments of $272 million largely due to investments in the first six months of 2019 in 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.

Financing activities were a net $1.87 billion source of cash in the first six months of 2020 compared to a net $1.84 billion use of cash in the first six months of 2019.
Long-term debt borrowings and repayments were a net $3.26 billion source of cash in the first six months of 2020 compared to a net $848 million source of cash in the first six months of 2019. During the first six months of 2020, MPC issued $2.5 billion of senior notes, borrowed and repaid $3.5 billion under its revolving credit facility, borrowed and repaid $1.18 billion under its trade receivables facility and MPLX had net borrowings of $825 million under its revolving credit facility. During the first six months of 2019, MPLX had net borrowings of $615 million under its revolving credit facility and ANDX had net borrowings of $255 million under its revolving credit facilities.
Cash used in common stock repurchases decreased $1.39 billion in the first six months of 2020 compared to the first six months of 2019. There were no share repurchases in the first six months of 2020 compared to $1.39 billion in the first six months of 2019. See Note 8 to the unaudited consolidated financial statements for further discussion of share repurchases.
Cash used in dividend payments increased $49 million in the first six months of 2020 compared to the first six months of 2019, primarily due to a $0.10 per share increase in our base dividend, partially offset by a reduction of shares resulting from share repurchases in 2019. Our dividend payments were $1.16 per common share in the first six months of 2020 compared to $1.06 per common share in the first six months of 2019.
Contributions from noncontrolling interests decreased $95 million in the first six months of 2020 compared to the first six 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.

(b) 
Outstanding borrowings include $1 million in letters of credit outstanding under this facility.
(c) 
Availability under our $750 million trade receivables facility is a function of eligible trade receivables, which will be lower in a sustained lower price environment for refined products.
(d) 
Excludes MPLX cash and cash equivalents of $67 million.
Because of the alternatives available to us, including internally generated cash flow and access to capital markets and a commercial paper program, we believe that our short-term and long-term liquidity is adequate to fund not only our current operations, but also our near-term and long-term funding requirements, including capital spending programs, dividend payments, defined benefit plan contributions, repayment of debt maturities, the repurchase of shares of our common stock and other amounts that may ultimately be paid in connection with contingencies.
We have a commercial paper program that allows us to have a maximum of $2.0 billion in commercial paper outstanding. We do not intend to have outstanding commercial paper borrowings in excess of available capacity under our bank revolving credit facility. As of June 30, 2020, we had no commercial paper borrowings outstanding.
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.
On April 27, 2020, MPC closed on the issuance of $2.5 billion in aggregate principal amount of senior notes in a public offering, consisting of $1.25 billion aggregate principal amount of 4.500 percent unsecured senior notes due 2023 and $1.25 billion aggregate principal amount of 4.700 percent unsecured senior notes due 2025. MPC used the net proceeds from this offering to repay certain amounts outstanding under its five-year revolving credit facility.
The MPC credit agreements and our trade receivables facility contain representations and warranties, affirmative and negative covenants and events of default that we consider usual and customary for agreements of these types. The financial covenant included in the MPC credit agreements requires us to maintain, as of the last day of each fiscal quarter, a ratio of Consolidated Net Debt to Total Capitalization (as defined in the MPC credit agreements) of no greater than 0.65 to 1.00. As of June 30, 2020, we were in compliance with the covenants contained in the MPC bank revolving credit facility and our trade receivables facility, including the financial covenant with a ratio of Consolidated Net Debt to Total Capitalization of 0.34 to 1.00.

Our intention is to maintain an investment-grade credit profile. As of June 30, 2020, the credit ratings on our senior unsecured debt are as follows.
 
Company
Rating Agency
Rating
MPC
Moody’s
Baa2 (negative outlook)
 
Standard & Poor’s
BBB (negative outlook)
 
Fitch
BBB (negative outlook)
The ratings reflect the respective views of the rating agencies. Although it is our intention to maintain a credit profile that supports an investment-grade rating, there is no assurance that these ratings will continue for any given period of time. The ratings may be revised or withdrawn entirely by the rating agencies if, in their respective judgments, circumstances so warrant.
None of the MPC credit agreements or our trade receivables facility contains credit rating triggers that would result in the acceleration of interest, principal or other payments in the event that our credit ratings are downgraded. However, any downgrades of our senior unsecured debt could increase the applicable interest rates, yields and other fees payable under such agreements and may limit our flexibility to obtain financing in the future, including to refinance existing indebtedness. In addition, a downgrade of our senior unsecured debt rating to below investment-grade levels could, under certain circumstances, decrease the amount of trade receivables that are eligible to be sold under our trade receivables facility, impact our ability to purchase crude oil on an unsecured basis and could result in us having to post letters of credit under existing transportation services or other agreements.
See Note 17 to the unaudited consolidated financial statements for further discussion of our debt.

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 June 30, 2020, MPLX was in compliance with the covenants, including the financial covenant with a ratio of Consolidated Total Debt to Consolidated EBITDA of 3.9 to 1.0.
Our intention is to maintain an investment-grade credit profile for MPLX. As of June 30, 2020, the credit ratings on MPLX’s senior unsecured debt are as follows.

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.

Other Capital Requirements
During the six months ended June 30, 2020, we contributed $3 million to our funded pension plans. We may choose to make additional contributions to our pension plans.
On July 29, 2020, our board of directors approved a dividend of $0.58 per share on common stock. The dividend is payable September 10, 2020, to shareholders of record as of the close of business on August 19, 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 six months ended June 30, 2020, share repurchases were temporarily suspended which helped preserve our liquidity during the COVID-19 pandemic. The company will evaluate the timing of future repurchases as market conditions evolve. 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 June 30, 2020. The table below summarizes our total share repurchases for the six months ended June 30, 2020 and 2019. See Note 8 to the unaudited consolidated financial statements for further discussion of the share repurchase plans.

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 June 30, 2020, our contractual cash obligations included long-term debt, capital and operating lease obligations, purchase obligations and other long-term liabilities. During the first six months of 2020, our long-term debt commitments increased approximately $3.1 billion primarily due to $2.5 billion of MPC senior notes issued and borrowings under the MPLX bank revolving credit facility.
During the first six months of 2020, 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 six months ended June 30, 2020.
CRITICAL ACCOUNTING ESTIMATES
As of June 30, 2020, there have been no significant changes to our critical accounting estimates since our Annual Report on Form 10-K for the year ended December 31, 2019 except as noted below.
Impairment Assessments of Long-Lived Assets, Intangible Assets, Goodwill and Equity Method Investments
Fair value calculated for the purpose of testing our long-lived assets, intangible assets, goodwill and equity method investments for impairment is estimated using the expected present value of future cash flows method and comparative market prices when appropriate. Significant judgment is involved in performing these fair value estimates since the results are based on forecasted financial information prepared using significant assumptions including:
Future operating performance. Our estimates of future operating performance are based on our analysis of various supply and demand factors, which include, among other things, industry-wide capacity, our planned utilization rate, end-user demand, capital expenditures and economic conditions. Such estimates are consistent with those used in our planning and capital investment reviews.
Future volumes. Our estimates of future refinery, 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 of our refinery asset groups within the Refining & Marketing segment as a result of decreases to the Refining & Marketing segment expected future cash flows. The cash flows associated with these assets were significantly impacted by the effects of COVID-19 and commodity price declines. We assessed each refinery asset group for impairment by comparing the undiscounted estimated pretax cash flows to the carrying value of each asset group. Of the 16 refinery asset groups, only the Gallup refinery’s carrying value exceeded its undiscounted estimated pretax cash flows. It was determined that the fair value of the Gallup refinery’s property,

56

Table of Contents
                            

plant and equipment was less than the carrying value. As a result, we recorded a charge of $142 million in the first quarter of 2020 to impairment expense on the consolidated statements of income. The fair value measurements for the Gallup refinery assets represent Level 3 measurements.
During the second quarter of 2020, we identified long-lived asset impairment triggers relating to all of our refinery asset groups within the Refining & Marketing segment, except the Gallup refinery which had been impaired in the first quarter, as a result of continued macroeconomic developments impacting the Refining & Marketing segment expected future cash flows. All of these refinery asset groups undiscounted estimated pretax cash flows exceeded the carrying value by at least 17 percent. On August 3, 2020, we announced our plans to evaluate possibilities to strategically reposition our Martinez refinery, including the potential conversion of the refinery into a renewable diesel facility. The outcome of our evaluation could result in an impairment triggering event and significantly change the assumptions and results of a future impairment test for the refinery’s long-lived assets.
The determination of undiscounted estimated pretax cash flows for our long-lived asset impairment tests utilized significant assumptions including management’s best estimates of the expected future cash flows, allocation of certain Refining & Marketing segment cash flows to the individual refineries, the estimated useful lives of the asset groups, and the salvage values of the refineries. The determinations of expected future cash flows and the salvage values of refineries require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of our impairment analysis will prove to be an accurate prediction of the future. Should our assumptions significantly change in future periods, it is possible we may determine the carrying values of additional refinery asset groups exceed the undiscounted estimated pretax cash flows of their refinery asset groups, which would result in future impairment charges.
During the first quarter of 2020, MPLX identified an impairment trigger relating to asset groups within its Western Gathering & Processing (“G&P”) reporting unit as a result of significant changes to expected future cash flows for these asset groups resulting from the effects of COVID-19. The cash flows associated with these assets were significantly impacted by volume declines reflecting decreased forecasted producer customer production as a result of lower commodity prices. MPLX assessed each asset group within the Western G&P reporting unit for impairment. It was determined that the fair value of the East Texas G&P asset group’s underlying assets was less than the carrying value. As a result, MPLX recorded impairment charges totaling $350 million related to its property, plant and equipment and intangibles, which are included in impairment expense on our consolidated statements of income. Fair value of MPLX’s PP&E was determined using a combination of an income and cost approach. The income approach utilized significant assumptions including management’s best estimates of the expected future cash flows and the estimated useful life of the asset group. The cost approach utilized assumptions for the current replacement costs of similar assets adjusted for estimated depreciation and deterioration of the existing equipment. The fair value of the intangibles was determined based on applying the multi-period excess earnings method, which is an income approach. Key assumptions included management’s best estimates of the expected future cash flows from existing customers, customer attrition rates and the discount rate. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the impairment analysis will prove to be an accurate prediction of the future. The fair value measurements for the asset group fair values represent Level 3 measurements.
Unlike long-lived assets, goodwill is subject to annual, or more frequent if necessary, impairment testing at the reporting unit level. A goodwill impairment loss is measured as the amount by which a reporting unit's carrying value exceeds its fair value, without exceeding the recorded amount of goodwill.
The “Business Update” under Recent Developments in the Corporate Overview section describes the effects that the outbreak of COVID-19, its development into a pandemic and the effect the decline in commodity prices during the first quarter of 2020 have had on our business. Due to these developments, we performed impairment assessments during the first quarter of 2020 as discussed further below.
Prior to performing our goodwill impairment assessment as of March 31, 2020, we had goodwill totaling approximately $20 billion associated with eight of our 10 reporting units. As part of this assessment, we recorded goodwill impairment expenses of $7.33 billion in the first quarter of 2020 related to our Refining & Marketing and MPLX’s Eastern G&P reporting units. The Refining & Marketing and Eastern G&P reporting units recorded goodwill impairment charges of $5.52 billion and $1.81 billion, respectively, which fully impaired both reporting units’ historical goodwill balances. These goodwill impairment expenses are primarily driven by the effects of COVID-19, the decline in commodity prices and the slowing of drilling activity which has reduced production growth forecasts from MPLX’s producer customers. For the remaining six reporting units with goodwill, we determined that no significant adjustments to the carrying value of goodwill were necessary. The impairment assessment performed as of March 31, 2020 resulted in the fair value of the reporting units exceeding their carrying value by percentages ranging from approximately 8.5 percent to 270.0 percent. MPLX’s Crude Gathering reporting unit had goodwill

57

Table of Contents
                            

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 June 30, 2020 we had $5.74 billion of equity method investments recorded on the Consolidated Balance Sheets.
An estimate of the sensitivity to net income resulting from impairment calculations is not practicable, given the numerous assumptions (e.g., pricing, volumes and discount rates) that can materially affect our estimates. That is, unfavorable adjustments to some of the above listed assumptions may be offset by favorable adjustments in other assumptions.

We remain at risk for possible changes in the market value of commodity derivative instruments; however, such risk should be mitigated by price changes in the underlying physical commodity. Effects of these offsets are not reflected in the above sensitivity analysis.
We evaluate our portfolio of commodity derivative instruments on an ongoing basis and add or revise strategies in anticipation of changes in market conditions and in risk profiles. Changes to the portfolio after June 30, 2020 would cause future IFO effects to differ from those presented above.
Sensitivity analysis of the effect of a hypothetical 100-basis-point change in interest rates on long-term debt, including the portion classified as current and excluding finance leases, as of June 30, 2020 is provided in the following table. Fair value of cash and cash equivalents, receivables, accounts payable and accrued interest approximate carrying value and are relatively insensitive to changes in interest rates due to the short-term maturity of the instruments. Accordingly, these instruments are excluded from the table.

At June 30, 2020, our portfolio of long-term debt was comprised of fixed-rate instruments and variable-rate borrowings. The fair value of our fixed-rate debt is relatively sensitive to interest rate fluctuations. Our sensitivity to interest rate declines and corresponding increases in the fair value of our debt portfolio unfavorably affects our results of operations and cash flows only when we elect to repurchase or otherwise retire fixed-rate debt at prices above carrying value. Interest rate fluctuations generally do not impact the fair value of borrowings under our variable-rate debt, but may affect our results of operations and cash flows.
See Note 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 June 30, 2020, the end of the period covered by this report.
Changes in Internal Control over Financial Reporting
During the quarter ended June 30, 2020, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
We are the subject of, or a party to, a number of pending or threatened legal actions, contingencies and commitments involving a variety of matters, including laws and regulations relating to the environment. Except as described below, there have no material changes to the legal proceedings previously disclosed in our Annual Report on Form 10-K, as updated in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020.
Litigation
Kentucky Litigation
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. On June 1, 2020, the trial court granted our motion for summary judgment and dismissed all federal law claims with prejudice. State-based claims were dismissed without prejudice.
Dakota Access Pipeline
In connection with MPLX’s 9.19 percent indirect interest in a joint venture (“Dakota Access”) that owns and operates the Dakota Access Pipeline and Energy Transfer Crude Oil Pipeline projects, collectively referred to as the Bakken Pipeline system or DAPL, MPLX has entered into a Contingent Equity Contribution Agreement whereby MPLX LP, along with the other joint venture owners in the Bakken Pipeline system, 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.
As previously disclosed in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, in March 2020, the U.S. District Court for the District of Columbia (the “D.D.C.”) ordered the U.S. Army Corps of Engineers (“Army Corps”), which granted permits 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.
On July 6, 2020, the D.D.C. ordered vacatur of the easement permit during the pendency of an EIS and further ordered a shut down of the pipeline by August 5, 2020. The D.D.C. denied a motion to stay that order. Dakota Access and the Army Corps are appealing the D.D.C.’s orders to the U.S. Court of Appeals for the District of Columbia Circuit. On July 14, 2020, the Circuit Court issued an administrative stay while the court considers Dakota Access and the Army Corps’ emergency motion for stay pending appeal.
If the pipeline is temporarily shut down pending completion of the EIS, MPLX would have to contribute its 9.19 percent pro rata share of funds required to pay interest accruing on the notes and any portion of the principal that matures while the pipeline is shutdown. It is also expected that MPLX would contribute its 9.19 percent pro rata share of any costs to remediate any deficiencies to reinstate the permit and/or return the pipeline into operation. If the vacatur of the easement permit results in a permanent shutdown of the pipeline, MPLX would have to contribute its 9.19 percent pro rata share of the cost to redeem the bonds (including the one percent redemption premium required pursuant to the indenture governing the notes) and any accrued and unpaid interest.
Tesoro High Plains Pipeline
In early July, MPLX received a Notification of Trespass Determination from the Bureau of Indian Affairs (“BIA”) relating to a portion of the pipeline that crosses the Fort Berthold Reservation in North Dakota. The notification covers the rights of way for 23 tracts of land and demands the immediate cessation of pipeline operations. The notification also assesses trespass damages of approximately $187 million. MPLX expects to receive a notification for an additional 11 tracts in the near future. MPLX appealed this determination, which triggered an automatic stay of the requested pipeline shutdown and payment. We believe the trespass damage calculation is dependent on a novel interpretation of the applicable law, and MPLX continues to actively negotiate settlement of this matter with holders of the property rights at issue. Management does not believe the ultimate resolution of this matter will have a material adverse effect on our consolidated financial position, results of operations, or cash flows.

Environmental Proceedings
Gathering and Processing
On May 7, 2020, MPLX received a show cause letter from the U.S. EPA relating to alleged violations relating to MPLX’s compliance under its Sarsen facility LDAR consent decree. MPLX has reached a settlement in principle to resolve this matter with a cash penalty of $150,000. We expect the settlement will be finalized and the penalty will be paid in the third quarter of 2020.
On May 13, 2020, MPLX received an offer from the Texas Commission on Environmental Quality to settle alleged violations relating to the installation of high bleed pneumatic controllers at its Hancock Compressor Station and Carthage East Gas Plant. MPLX has reached an agreement to settle this matter for a cash penalty of $165,600.
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, as updated in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020.
Our pending sale of Speedway to 7-Eleven, Inc. is subject to conditions, including certain conditions that may not be satisfied or completed on a timely basis, if at all. Failure to complete the Speedway sale could have a material and adverse effect on us. Even if completed, the Speedway sale may not achieve the intended benefits.
We have announced our agreement to sell Speedway, our company-owned and operated retail transportation fuel and convenience store business, to 7-Eleven, Inc. The sale, which is targeted for completion in the first quarter of 2021, is subject to customary conditions, including obtaining necessary regulatory approvals. We and 7-Eleven, Inc. may be unable to satisfy such conditions to the closing of the sale in a timely manner or at all and, accordingly, the Speedway sale may be delayed or may not be completed. Failure to complete the Speedway sale could have a material and adverse effect on us, including by delaying our strategic and other objectives relating to the separation of Speedway and adversely affecting our plans to use the proceeds from the sale to reduce our leverage and return capital to our shareholders. Even if the sale is completed, we may not realize some or all the expected benefits. For example, we may be unable to utilize the proceeds from the sale as anticipated or capture the value we expect from our plans to reduce our leverage and return capital to our shareholders. Executing the Speedway sale will require significant time and attention from management, which could divert attention from the management of our operations and the pursuit of our business strategies. If the proposed Speedway sale is completed, our diversification of revenue sources will diminish, and it is possible that our business, financial condition, results of operations and cash flows may be subject to increased volatility as a result.

ITEM 5. OTHER INFORMATION
On July 31, 2020, Western Refining Southwest, Inc., an Arizona corporation (“WRSW”) and wholly owned subsidiary of MPC, entered into a Redemption Agreement (the “Redemption Agreement”) with MPLX, pursuant to which MPLX agreed to transfer, following a series of intercompany transactions, all of the outstanding membership interests in Western Refining Wholesale, LLC, a Delaware limited liability company (“WRW”) to WRSW in exchange for the redemption of MPLX common units held by WRSW.  The transaction effects the transfer to MPC of the Western wholesale distribution business that MPLX acquired as a result of its acquisition of ANDX. The Redemption Agreement was approved by the conflicts committee and the board of directors of MPLX’s general partner. The conflicts committee, which is composed of independent members of the board of directors of MPLX’s general partner, retained independent legal and financial advisors to assist it in evaluating and negotiating the transaction.
Consistent with the terms of the Redemption Agreement, effective as of 11:59 p.m. on July 31, 2020 (the “Closing”), all of the outstanding membership interests in WRW were transferred to WRSW, and WRW became an indirect, wholly owned subsidiary of MPC. At the Closing, per the terms of Redemption Agreement, MPLX redeemed 18,582,088 Common Units (the “Redeemed Units”) held by WRSW. The number of Redeemed Units was calculated by dividing WRW’s aggregate valuation of $340 million by the simple average of the volume weighted average New York Stock Exchange prices of an MPLX common unit for the ten trading days ending at market close on July 27, 2020. Following the redemption of the Redeemed Units, and consistent with the terms of the Redemption Agreement, MPLX cancelled the Redeemed Units.
After giving effect to transactions contemplated under the Redemption Agreement (including the cancellation of the Redeemed Units as described above), MPC holds, indirectly through its subsidiaries, 647,415,452 common units constituting approximately 62% of the MPLX common units issued and outstanding as of August 3, 2020.
Each of MPLX and WRSW has agreed to customary representations, warranties and covenants, as well as customary indemnification obligations between the parties, in the Redemption Agreement.
The foregoing description of the Redemption Agreement is not complete and is qualified in its entirety by reference to the full text of the Redemption Agreement, which is filed as Exhibit 99.1 to this Quarterly Report on Form 10-Q and incorporated by reference herein.
