NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION

Description of the Business

We are a leading, integrated, downstream energy company headquartered in Findlay, Ohio. We operate the nation's largest refining system with more than 3 million barrels per day of crude oil capacity across 16 refineries. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to consumers through our Retail business segment and to independent entrepreneurs who operate approximately ~~6,900~~7,000 branded outlets. Our retail operations own and operate approximately ~~3,920~~3,910 retail transportation fuel and convenience stores across the United States and also sell transportation fuel to consumers through approximately 1,060 direct dealer locations under long-term supply contracts. MPC’s midstream operations are primarily conducted through MPLX LP (“MPLX”) and Andeavor Logistics LP (“ANDX”), which own and operate crude oil and light product transportation and logistics infrastructure as well as gathering, processing, and fractionation assets. We own the general partner and majority limited partner ~~interest~~interests in these two midstream companies.

Refer to Note 4 for further information on the Andeavor acquisition, which closed on October 1, 2018, and to Notes 3 and 9 for additional information about our operations.

Basis of Presentation

All significant intercompany transactions and accounts have been eliminated.

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, 2018. The results of operations for the three and six months ended ~~March 31,~~June 30, 2019 are not necessarily indicative of the results to be expected for the full year.

2. ACCOUNTING STANDARDS

Recently Adopted

ASU 2016-02, Leases

We adopted ASU No. 2016-02, Leases ~~(��~~(“ASC 842”), as of January 1, 2019, electing the transition method which permits entities to adopt the provisions of the standard using the modified retrospective approach without adjusting comparative periods. We also elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to grandfather the historical accounting conclusions until a reassessment event is present. We have also elected the practical expedient to not recognize short-term leases on the balance sheet, the practical expedient related to right of way permits and land easements which allows us to carry forward our accounting treatment for those existing agreements, and the practical expedient to combine lease and non-lease components for the majority of our underlying classes of assets except for our third-party contractor service and equipment agreements and boat and barge equipment agreements in which we are the lessee. We did not elect the practical expedient to combine lease and non-lease components for arrangements in which we are the lessor. In instances where the practical expedient was not elected, lease and non-lease consideration is allocated based on relative standalone selling price.

Right of use (“ROU”) assets represent our right to use an underlying asset in which we obtain substantially all of the economic benefits and the right to direct the use of the asset during the lease term. Lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We recognize ROU assets and lease liabilities on the balance sheet for leases with a lease term of greater than one year. Payments that are not fixed at the commencement of the lease are considered variable and are excluded from the ROU asset and lease liability calculations. In the measurement of our ROU assets and lease liabilities, the fixed lease payments in the agreement are discounted using a secured incremental borrowing rate for a term similar to the duration of the lease, as our leases do not provide implicit rates. Operating lease expense is recognized on a straight-line basis over the lease term.

Table of Contents

Adoption of the new standard resulted in the recording of ROU assets and lease liabilities of approximately ~~$2.79~~$2.81 billion and ~~$2.88~~$2.90 billion, respectively, as of January 1, 2019. The standard did not materially impact our consolidated statements of income, cash flows or equity as a result of adoption.

As a lessor under ASC 842, MPLX may be required to re-classify existing operating leases to sales-type leases upon modification and related reassessment of the leases. If such a modification were to occur, it may result in the de-recognition of existing assets, recognition of a receivable in the amount of the present value of fixed payments expected to be received by MPLX under the lease, and recognition of a corresponding gain or loss in the period of change. MPLX will evaluate the impact of a lease reassessment as modifications occur.

We also adopted the following ASUs during the first ~~three~~six months of 2019, none of which had a material impact to our financial statements or financial statement disclosures:



ASU		Effective Date
2018-02	Reporting Comprehensive Income - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income	January 1, 2019
2017-12	Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities	January 1, 2019

Not Yet Adopted

ASU 2017-04, Intangibles - Goodwill and Other - Simplifying the Test for Goodwill Impairment

In January 2017, the FASB issued an ASU which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under the new guidance, the recognition of an impairment charge is calculated based on the amount by which the carrying amount exceeds the reporting unit’s fair value, which could be different from the amount calculated under the current method using the implied fair value of the goodwill; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The guidance should be applied on a prospective basis and is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019.

ASU 2016-13, Credit Losses - Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued an ASU related to the accounting for credit losses on certain financial instruments. The guidance requires that for most financial assets, losses be based on an expected loss approach which includes estimates of losses over the life of exposure that considers historical, current and forecasted information. Expanded disclosures related to the methods used to estimate the losses as well as a specific disaggregation of balances for financial assets are also required. The change is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. We do not expect application of this ASU to have a material impact on our consolidated financial statements.

3. MASTER LIMITED PARTNERSHIPS

~~MPLX~~

We own the general partner and majority limited partner interests in two midstream companies, MPLX ~~is a diversified, large-cap publicly traded limited partnership formed by us to~~and ANDX, which own and operate ~~develop~~gathering, processing, and ~~acquire midstream energy infrastructure assets. MPLX is engaged in the transportation, storage and distribution of~~fractionation assets, as well as crude oil and ~~refined petroleum products; gathering, processing~~light product transportation and ~~transportation of natural gas; and the gathering, transportation, fractionation, storage and marketing of NGLs.~~logistics infrastructure. As of ~~March 31,~~June 30, 2019, we owned 64 percent of the outstanding ~~MPLX~~ common units of both MPLX and weANDX. We control both MPLX and ANDX through our ownership of the general partner interest.

As described in Notes 4 and 5, we have consolidated ANDX since October 1, 2018 in accordance with ASC 810 and previously recorded ANDX’s assets and liabilities to our balance sheet at preliminary fair values as of ~~MPLX.~~the Andeavor acquisition date of October 1, 2018.

On July 30, 2019, MPLX completed its acquisition of ANDX. 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. ANDX common unitholders will not receive any future distributions from ANDX, but instead will receive a second quarter 2019 distribution as and when declared by the Board of Directors of MPLX with respect to the MPLX common units issued in connection with the acquisition. Additionally, the ANDX Series A Preferred unitholders will not receive any future distributions from ANDX, but instead will receive the semi-annual distributions payable August 15, 2019 on MPLX Series B Preferred units issued in connection with the acquisition. As of July 30, 2019, MPC will account for this transaction as a common control transaction, as defined by ASC 805, which will result in adjustments to our noncontrolling interest and additional paid-in capital balances.

Dropdowns to MPLX and GP/IDR Exchange

On February 1, 2018, we contributed refining logistics assets and fuels distribution services to MPLX in exchange for $4.1 billion in cash and approximately 112 million common units and 2 million general partner units from MPLX. MPLX financed the cash portion of the transaction with its $4.1 billion 364-day term loan facility, which was entered into on January 2, 2018. We agreed to waive approximately one-third of the first quarter 2018 distributions on the common units issued in connection with this transaction. The contributions of these assets were accounted for as transactions between entities under common control and we did not record a gain or loss.

Immediately following the February 1, 2018 dropdown to MPLX, our IDRs were cancelled and our economic general partner interest was converted into a non-economic general partner interest, all in exchange for 275 million newly issued MPLX common units (“GP/IDR Exchange”). As a result of this transaction, the general partner units and IDRs were eliminated, are no longer outstanding and no longer participate in distributions of cash from MPLX.

~~Table of Contents~~

Agreements

We have various long-term, fee-based commercial agreements with ~~MPLX.~~MPLX and ANDX. Under these agreements, MPLX ~~provides~~and ANDX provide transportation, storage, distribution and marketing services to us. Under certain agreements, we commit to provide MPLX with minimum throughput and distribution volumes of crude oil and refined products and minimum storage volumes of crude oil, refined products and butane. Under certain other agreements, we commit to pay for substantially all of the available capacity for certain marine transportation and refining logistics assets. 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.

~~ANDX~~

Through the Andeavor acquisition, we acquired control of ANDX, which is a publicly traded limited partnership that was formed to own, operate, develop and acquire logistics assets. Its assets are integral to the success of our refining and marketing operations and are used to gather crude oil, natural gas, and water, process natural gas and distribute, transport and store crude oil and refined products. ANDX provides us with various pipeline transportation, trucking, terminal distribution, storage and petroleum-coke handling services under long-term, fee-based commercial agreements. 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 and ANDX that establish fees for operational and management services provided between us and MPLX and ANDX and for executive management services and certain general and administrative services provided by us to MPLX and ANDX. These transactions are eliminated in consolidation but are reflected as intersegment transactions between our Corporate and Midstream segments.

As of March 31, 2019, we owned 64 percent of the outstanding ANDX common units. We also hold 80,000 ANDX TexNew Mex Units as of March 31, 2019 and control ANDX through our ownership of the general partner of ANDX.

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. ACQUISITIONS

Acquisition of Andeavor

On October 1, 2018, we acquired ~~all the outstanding shares of~~ Andeavor. The total value of consideration transferred was $23.46 billion, consisting of $19.97 billion in equity and $3.49 billion in cash. The cash portion of the purchase price was funded using cash on hand. Our financial results reflect the results of Andeavor from the date of the acquisition.

We accounted for the Andeavor acquisition using the acquisition method of accounting, which requires Andeavor assets and liabilities to be recorded to our balance sheet at fair value as of the acquisition date. We will complete a final determination of the fair value of certain assets and liabilities within the one year measurement period from the date of the acquisition as required by ~~FASB~~ ASC ~~Topic 805, “Business Combinations”.~~805. Due to the level of effort required to develop fair value measurements, the valuation studies necessary to determine the fair value of assets acquired and liabilities assumed are preliminary, including the underlying cash flows used to determine the fair value of identified intangible assets and economic obsolescence adjustments to property, plant and equipment. The size and the breadth of the Andeavor acquisition necessitates the use of the one year measurement period to fully analyze all the factors used in establishing the asset and liability fair values as of the acquisition date, including, but not limited to, property, plant and equipment, intangible assets, real property, leases,

~~Table of Contents~~

environmental and asset retirement obligations and the related tax impacts of any changes made. Any potential adjustments made could be material in relation to the preliminary values.

Table of Contents

During the ~~three~~six months ended ~~March 31,~~June 30, 2019, we recorded adjustments to the preliminary fair value estimates of assets acquired and liabilities assumed as of the acquisition date as noted in the table below.

^(a)	Includes intangible assets.

The preliminary purchase consideration allocation resulted in the recognition of ~~$16.38~~$16.43 billion in goodwill, of which $893 million is tax deductible due to a carryover basis from Andeavor. Our Refining & Marketing, Midstream and Retail segments recognized ~~$4.78~~$4.82 billion, $7.72 billion and ~~$3.88~~$3.89 billion of preliminary ~~goodwill.~~goodwill, respectively. The recognized goodwill represents the value expected to be created by further optimization of crude supply, a nationwide retail and marketing platform, diversification of our refining and midstream footprints and optimization of information systems and business processes.

Pro Forma Financial Information

The following unaudited pro forma financial information presents consolidated results assuming the Andeavor acquisition occurred on January 1, 2017. The unaudited pro forma information does not give effect to potential synergies that could result from the transaction and is not necessarily indicative of the results of future operations.

Acquisition of Express Mart

During the fourth quarter of 2018, Speedway acquired 78 transportation fuel and convenience store locations from Petr-All Petroleum Consulting Corporation for total consideration of $266 million. These stores are located primarily in the Syracuse, Rochester and Buffalo markets in New York and had been operated under the Express Mart brand.

Based on the final fair value estimates of assets acquired and liabilities assumed at the acquisition date, $97 million of the purchase price was allocated to property, plant and equipment, $9 million to inventory, $2 million to intangibles and $158 million to goodwill. Goodwill is tax deductible and represents the value expected to be created by geographically expanding our retail platform and the assembled workforce. These operations are accounted for within the Retail segment.

Acquisition of Mt. Airy Terminal

On September 26, 2018, MPLX acquired an eastern U.S. Gulf Coast export terminal (“Mt. Airy Terminal”) from Pin Oak Holdings, LLC for total consideration of $451 million. At the time of the acquisition, the terminal included tanks with 4 million barrels of third-party leased storage capacity and a dock with 120 mbpd of capacity. The Mt. Airy Terminal is located on the Mississippi River between New Orleans and Baton Rouge, near several Gulf Coast refineries, including our Garyville Refinery, and numerous rail lines and pipelines. The Mt. Airy Terminal is accounted for within the Midstream segment. In the first quarter of 2019, an adjustment to the initial purchase price was made for approximately $5 million related to the final settlement of the acquisition. This reduced the total purchase price to $446 million and resulted in $336 million of property, plant and equipment, $121 million of goodwill and the remainder being attributable to net liabilities assumed.

Goodwill represents the significant growth potential of the terminal due to the multiple pipelines and rail lines which cross the property, the terminal’s position as an aggregation point for liquids growth in the region for both ocean-going vessels and inland barges, the proximity of the terminal to MPC’s Garyville refinery and other refineries in the region as well as the opportunity to construct an additional dock at the site. All of the goodwill recognized related to this transaction is tax deductible.

Assuming the acquisitions of Express Mart and Mt. Airy Terminal had occurred on January 1, 2017, the consolidated pro forma results would not have been materially different from the reported results.

5. VARIABLE INTEREST ENTITIES

Consolidated VIEs

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

The creditors of MPLX and ANDX 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 2423 for more information. Western Refining Southwest, Inc., a wholly-owned subsidiary of MPC and unitholder of ANDX, has guaranteed certain outstanding borrowings under the ANDX dropdown credit facility that were made in connection with the August 2018 dropdown transaction.

7. ~~INCOME (LOSS)~~EARNINGS PER ~~COMMON~~ SHARE

We compute basic earnings per share by dividing net income 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 per share using the two-class method. Diluted income per share assumes exercise of certain stock-based compensation awards, provided the effect is not anti-dilutive.

8. EQUITY

As of ~~March 31,~~June 30, 2019, we had ~~$4.02~~$3.52 billion of share repurchase authorization remaining under authorizations from our board of directors. We may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block transactions, 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:

9. SEGMENT INFORMATION

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

•

Refining & Marketing – refines crude oil and other feedstocks at our 16 refineries in the ~~West~~Gulf Coast, Mid-Continent and ~~Gulf~~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 primarily 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 and ~~ANDX, our sponsored master limited partnerships.~~ANDX.

Segment income represents income from operations attributable to the reportable segments. Corporate administrative expenses, except for those attributable to MPLX and ANDX, 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

The combined federal, state and foreign income tax rate was 2921 percent and 919 percent for the three months ended ~~March 31,~~June 30, 2019 and 2018, respectively, and 22 percent and 17 percent for the six months ended June 30, 2019 and 2018, respectively. The effective tax rate for the three months ended ~~March 31,~~June 30, 2019 was equal to the U.S. statutory rate of 21 percent primarily due to certain permanent tax differences related to net income attributable to noncontrolling interests offset by equity compensation and state and local tax expense. 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. The effective tax rate for the three and six months ended ~~March 31,~~June 30, 2018 was less than the U.S. statutory rate primarily due to certain permanent tax differences related to net income attributable to noncontrolling interests and equity compensation offset by state and local ~~deferred~~ tax ~~benefits primarily resulting from the February 1 dropdown and GP/IDR Exchange and equity compensation.~~expense.

During the first quarter of 2019, MPC’s deferred tax liabilities increased $68 million with an offsetting increase to goodwill and the provision for income taxes of ~~$32~~$32 million and $36 million, respectively 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~~2006 tax year for state returns and the 2008 tax year for our U.S. federal return. As of ~~March 31,~~June 30, 2019, we had ~~$231~~$202 million of unrecognized tax benefits.

Prior to its spinoff on June 30, 2011, Marathon Petroleum Corporation was included in the Marathon Oil Corporation (“Marathon Oil”) U.S. federal income tax returns for all applicable years. During the third quarter of 2017, Marathon Oil received a notice of Final Partnership Administrative Adjustment (“FPAA”) from the U.S. Internal Revenue Service for taxable year 2010, relating to certain partnership transactions. Marathon Oil filed a U.S. Tax Court petition disputing these adjustments during the fourth quarter of 2017. We received an FPAA for taxable years 2011-2014 for items resulting from this matter and filed a U.S. Tax Court petition for tax years 2011-2014 to dispute these corollary adjustments in the fourth quarter of 2017. We continue to believe that the issue in dispute is more likely than not to be fully sustained and, therefore, no liability has been accrued for this matter.

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 2423 for indemnification information.

There were no LIFO inventory liquidations recognized for the ~~three~~six months ended ~~March 31,~~June 30, 2019.

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 Capline pipeline system in exchange for a 33 percent ownership interest in Capline LLC. Concurrent with our execution of these agreements, Capline LLC initiated a binding open season for southbound service from Patoka, IL to St. James, LA or Liberty, MS, with an additional origination point at Cushing, OK. Service from Cushing, OK is part of a joint tariff with Diamond pipeline. Crude oil service is expected to begin in the third quarter of 2020.

Table of Contents

In accordance with ASC 810, ~~“Consolidation��,~~ 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 ~~determined~~estimated the fair value of our ownership interest ~~was estimated~~ to be $350 million as of January 30, 2019. 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

~~Table of Contents~~

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~~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 ~~March 31,~~June 30, 2019, cash collateral of ~~$33~~$3 million was netted with the mark-to-market derivative liabilities. As of December 31, 2018, cash collateral of $52 million was netted with mark-to-market derivative assets and $13 million was netted with mark-to-market derivative liabilities.


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

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

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

Level 3 instruments are OTC NGL contracts and embedded derivatives in commodity contracts. The embedded derivative liability relates to a natural gas purchase agreement embedded in a keep‑whole processing agreement. The fair value calculation for these Level 3 instruments at ~~March 31,~~June 30, 2019 used significant unobservable inputs including: (1) NGL prices interpolated and extrapolated due to inactive markets ranging from ~~$0.60~~$0.46 to ~~$1.25~~$1.14 per gallon and (2) the probability of renewal of 9192 percent for the first ~~five-year term~~five-term and 82 percent for the second ~~five-year term~~five-term of the natural gas purchase agreement and the related keep-whole processing agreement. For these contracts, increases in forward NGL prices result in a decrease in the fair value of the derivative assets and an increase in the fair value of the derivative liabilities. 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, which include variable interest rates, approximate fair value. The fair value of our fixed 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 ~~$27.6~~$27.9 billion and ~~$28.5~~$29.4 billion at ~~March 31,~~June 30, 2019, respectively, and approximately $27.0 billion and $26.5 billion at

December 31, 2018, respectively. These carrying and fair values of our debt exclude the unamortized issuance costs which are netted against our total debt.

16. DERIVATIVES

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

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

The following table presents the fair value of derivative instruments as of ~~March 31,~~June 30, 2019 and December 31, 2018 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.

^(a)	Western Refining Southwest, Inc., a wholly-owned subsidiary of MPC and unitholder of ANDX, has guaranteed certain outstanding borrowings under the ANDX dropdown credit facility that were made in connection with the August 2018 dropdown transaction.

MPC 364-Day Bank Revolving Credit Facility

On July 26, 2019, we entered into a new $1 billion 364-day revolving credit facility with a syndicate of banks that will, subject to the satisfaction of customary conditions, become effective upon the expiration of our existing $1 billion 364-day revolving credit facility in September 2019. The new 364-day revolving credit facility contains substantially the same terms and conditions as our existing 364-day revolving credit facility and will expire in September 2020.

MPC Trade Receivables Securitization Facility

On July 19, 2019, we amended our $750 million trade receivables securitization facility to extend the maturity date to July 16, 2021.

MPLX Credit Agreement

Upon the completion of the merger of MPLX and ANDX on July 30, 2019, the MPLX bank revolving credit facility was amended and restated to increase the borrowing capacity to $3.5 billion and to extend the maturity date to July 30, 2024. The ANDX revolving and dropdown credit facilities were terminated and all outstanding balances were repaid and funded with the new $3.5 billion bank revolving credit facility.

For further information regarding the adoption of ASC 842, including the method of adoption and practical expedients elected, see Note 2.

Lessee

We lease a wide variety of facilities and equipment including land and building space, office and field equipment, storage facilities and transportation equipment. Our remaining lease terms range from less than one year to 60 years. Most long-term leases include renewal options ranging from less than one year to 49 years and, in certain leases, also include purchase options. The lease term included in the measurement of right of use assets and lease liabilities includes options to extend or terminate our leases that we are reasonably certain to exercise. Options were included in the lease term primarily for retail store sites where we constructed property, plant and equipment on leased land that is expected to exist beyond the initial lease term.

Lessor

MPLX has certain natural gas gathering, transportation and processing agreements in which it is considered to be the lessor under several implicit operating lease arrangements in accordance with GAAP. MPLX’s primary implicit lease operations relate to a natural gas gathering agreement in the Marcellus region for which it earns a fixed-fee for providing gathering services to a single producer using a dedicated gathering system. As the gathering system is expanded, the fixed-fee charged to the producer is adjusted to include the additional gathering assets in the lease. The primary term of the natural gas gathering arrangement expires in 2038 and will continue thereafter on a year-to-year basis until terminated by either party. Other ~~significant~~ implicit leases relate to a natural gas processing agreement in the Marcellus region and a natural gas processing agreement in the Southern Appalachia region for which MPLX earns minimum monthly fees for providing processing services to a single producer using a dedicated processing plant. The primary term of these natural gas processing agreements expire during 2023 and 2033.

MPLX did not elect to use the practical expedient to combine lease and non-lease components for lessor arrangements. The tables below represent the portion of the contract allocated to the lease component based on relative standalone selling price. Lessor agreements are currently deemed operating, as we elected the practical expedient to grandfather in ~~old conclusions. We are still determining the impact of the new standard on these arrangements if and when a modification occurs and they are required to be assessed under~~historical ASC ~~842.~~840 lease classifications. MPLX may be required to re-classify existing operating leases to sales-type leases upon modification and related reassessment of the leases.

Our revenue from implicit lease arrangements, excluding executory costs, totaled approximately ~~$60~~$63 million inand $123 million for the three and six months ended ~~March 31, 2019.~~June 30, 2019, respectively. The implicit lease arrangements related to the processing facilities contain contingent rental provisions whereby we receive additional fees if the producer customer exceeds the monthly minimum processed volumes. During the three and six months ended ~~March 31,~~June 30, 2019, MPLX did not receive any material contingent lease payments. The following is a schedule of minimum future rentals on the non‑cancellable operating leases as of ~~March 31,~~June 30, 2019:

~~24.~~23. 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 ~~March 31,~~June 30, 2019 and December 31, 2018, accrued liabilities for remediation totaled ~~$451~~$449 million and $455 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 ~~$33~~$35 million and $35 million at ~~March 31,~~June 30, 2019 and December 31, 2018, respectively.

Governmental and other entities in California, New York, Maryland and Rhode Island have filed lawsuits against coal, gas, oil and petroleum companies, including the Company. The lawsuits allege damages as a result of climate change and the plaintiffs are seeking unspecified damages and abatement under various tort theories. Similar lawsuits may be filed in other jurisdictions. At this early stage, the ultimate outcome of these matters ~~remain~~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.

Lawsuits

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

In May 2007, the Kentucky attorney general filed a lawsuit against us and Marathon Oil in state court in Franklin County, Kentucky for alleged violations of Kentucky’s emergency pricing and consumer protection laws following Hurricanes Katrina and Rita in 2005. The lawsuit ~~alleges~~alleged that we overcharged customers by $89 million during September and October 2005. The complaint ~~seeks~~sought disgorgement of these sums, as well as penalties, under Kentucky’s emergency pricing and consumer protection laws. We are vigorously defending this litigation. We believe that this is the first lawsuit for damages and injunctive relief under the Kentucky emergency pricing laws to progress this far and it contains many novel issues. In May 2011, the Kentucky attorney general amended his complaint to include a request for immediate injunctive relief as well as unspecified damages and penalties related to our wholesale gasoline pricing in April and May 2011 under statewide price controls that were activated by the Kentucky governor on April 26, 2011 and which have since expired. The court denied the attorney general’s request for immediate injunctive ~~relief,~~relief. In July 2019, MPC and the ~~remainder of the 2011 claims likely~~attorney general reached a settlement to resolve this litigation. This resolution will be resolved along with those dating from 2005. If the lawsuit is resolved unfavorably in its entirety, it could materially impact our consolidated results of operations, financial position or cash flows. However, management does not ~~believe the ultimate resolution of this litigation will~~ have a material adverse effect on our consolidated financial position, results of operations or cash flows.

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

Guarantees

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

Guarantees related to indebtedness of equity method investees—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 vary but tend to follow the terms of the underlying debt, which extend through 2037. Our maximum potential undiscounted payments under these agreements for the debt principal totaled $171 million as of ~~March 31,~~June 30, 2019.

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 Pipeline is constructing the Gray Oak oil pipeline, 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 has 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 Gary 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 abandonment of the Gray Oak pipeline project prior to completion or the failure of Gray Oak Pipeline to repay or refinance the construction loan facility prior to its scheduled maturity date of June 3, 2022. Gray Oak may borrow up to $1.43 billion under the construction loan facility (after giving effect to the exercise of all options to increase its borrowing capacity). As of June 30, 2019, our maximum potential undiscounted payments under the Equity Contribution Agreement for the debt principal totaled $138 million.

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

Table of Contents

As of ~~March 31,~~June 30, 2019, our maximum potential undiscounted payments under the Contingent Equity Contribution Agreement was approximately $230 million.

In connection with our 50 percent indirect interest in Crowley Ocean Partners LLC, we have agreed to conditionally guarantee our portion of the obligations of the joint venture and its subsidiaries under a senior secured term loan agreement. The term loan agreement provides for loans of up to $325 million to finance the acquisition of four product tankers. MPC’s liability under the guarantee for each vessel is conditioned upon the occurrence of certain events, including if we cease to maintain an investment grade credit rating or the charter for the relevant product tanker ceases to be in effect and is not replaced by a charter with an investment grade company on certain defined commercial terms. As of ~~March 31,~~June 30, 2019, our maximum potential undiscounted payments under this agreement for debt principal totaled ~~$135~~$125 million.

~~Table of Contents~~

In connection with our 50 percent indirect interest in Crowley Blue Water Partners LLC, we have agreed to provide a conditional guarantee of up to 50 percent of its outstanding debt balance in the event there is no charter agreement in place with an investment grade customer for the entity’s three vessels as well as other financial support in certain circumstances. As of ~~March 31,~~June 30, 2019, our maximum potential undiscounted payments under this arrangement was $125 ~~million .~~million.

Marathon Oil indemnifications—In conjunction with our spinoff from Marathon Oil, we have entered into arrangements with Marathon Oil providing indemnities and guarantees with recorded values of $1 million as of ~~March 31,~~June 30, 2019, which consist of unrecognized tax benefits related to MPC, its consolidated subsidiaries and the refining, marketing and transportation business operations prior to our spinoff which are not already reflected in the unrecognized tax benefits described in Note 11, and other contingent liabilities Marathon Oil may incur related to taxes. Furthermore, the separation and distribution agreement and other agreements with Marathon Oil to effect our spinoff provide for cross-indemnities between Marathon Oil and us. In general, Marathon Oil is required to indemnify us for any liabilities relating to Marathon Oil’s historical oil and gas exploration and production operations, oil sands mining operations and integrated gas operations, and we are required to indemnify Marathon Oil for any liabilities relating to Marathon Oil’s historical refining, marketing and transportation operations. The terms of these indemnifications are indefinite and the amounts are not capped.

Other guarantees—We have entered into other guarantees with maximum potential undiscounted payments totaling $123 million as of ~~March 31,~~June 30, 2019, 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. See Note 5 for information regarding our guarantee of certain borrowings under the ANDX dropdown credit facility.

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

Contractual Commitments and Contingencies

At ~~March 31,~~June 30, 2019, our contractual commitments to acquire property, plant and equipment and advance funds to equity method investees totaled ~~$1.06~~$1.15 billion.

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.

~~25. SUBSEQUENT EVENT~~

On May 8, 2019, MPC, MPLX and ANDX announced that MPLX and ANDX have entered into a definitive merger agreement whereby MPLX will acquire ANDX in a unit-for-unit transaction. Under the terms of the merger agreement, ANDX public unitholders will receive 1.135 MPLX common units for each ANDX common unit held and MPC will receive 1.0328 MPLX common units for each ANDX common unit held. As described in Notes 4 and 5, we consolidate ANDX in accordance with ASC 810 and previously recorded ANDX’s assets and liabilities to our balance sheet at preliminary fair values as of the Andeavor acquisition date of October 1, 2018. Upon closing of this merger, we will account for the unit-for-unit transaction as a common control transaction, which will result in a change in our noncontrolling interest and additional paid-in capital.

CORPORATE OVERVIEW

We are a leading, integrated, downstream energy company. We own and operate the nation’s largest refining system with more than 3 million barrels per calendar day of crude oil capacity across 16 refineries, located in the ~~West~~Gulf Coast, Mid-Continent and ~~Gulf~~West Coast regions of the United States. Our refineries supply 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 branded outlets. 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^®. Approximately ~~6,900~~7,000 branded outlets, primarily carrying the Marathon brand name, are 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 transportation fuel and convenience stores in the United States, with approximately ~~3,920~~3,910 convenience stores. Our Retail segment also sells transportation fuel to consumers through approximately 1,060 direct dealer locations. Our company-owned and operated locations primarily carry the Speedway^® brand name and the direct dealer locations carry primarily the ARCO^® brand name.

We are one of the largest midstream operators in North America. We primarily conduct our midstream operations through our ownership ~~interests~~interest in MPLX, which owns and ~~ANDX, which own and operate~~operates crude oil and light product transportation and logistics infrastructure as well as gathering, processing, and fractionation assets. On July 30, 2019, MPLX acquired ANDX, as discussed below, to create a leading, large-scale diversified midstream company. As of ~~March 31,~~June 30, 2019, we owned, leased or had ownership interests in approximately 16,600 miles of crude oil and refined product pipelines to deliver crude oil to ourrefineries 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 gathering and processing 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. ~~As of March 31, 2019, our assets include approximately 9.9 bcf/d of gathering capacity, 11.1 bcf/d of natural gas processing capacity and 790 mbpd of fractionation capacity.~~

At ~~March 31,~~June 30, 2019, our operations consisted of 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.

•


•	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 primarily 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 and ANDX.

Recent Developments

On May 8, 2019, MPC, MPLX and ANDX announced that MPLX and ANDX have entered into a definitive merger agreement whereby MPLX will acquire ANDX in a unit-for-unit transaction at a blended exchange ratio of 1.07x. Under the terms of the merger agreement, ANDX public unitholders will receive 1.135 MPLX common units for each ANDX common unit held, representing a premium of 7.3 percent, and MPC will receive 1.0328 MPLX common units for each ANDX common unit held, representing a 2.4 percent discount, based on May 2, 2019 closing prices. As described in Notes 4 and 5 to the unaudited consolidated financial statements, we ~~consolidate~~have consolidated ANDX since October 1, 2018 in accordance with ASC 810 and previously recorded ANDX’s assets and liabilities to our balance sheet at preliminary fair values as of the Andeavor acquisition date of October 1, 2018. ~~Upon closing~~

On July 30, 2019, MPLX completed its acquisition of ~~this merger, we~~ANDX. 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. ANDX common unitholders will not receive any future distributions from ANDX but instead will receive a second quarter 2019 distribution as and when declared by the Board of Directors of MPLX with respect to the MPLX common units issued in connection with the acquisition. Additionally, the ANDX Series A Preferred unitholders will not receive any future distributions from ANDX, but instead will receive the semi-annual distributions payable August 15, 2019 on MPLX Series B Preferred units issued in connection with the acquisition. As of July 30, 2019, MPC will account for ~~the unit-for-unit~~this transaction as a common control transaction, as defined by ASC 805, which will result in ~~a change in~~adjustments to our noncontrolling interest and additional paid-in ~~capital.~~capital balances.

Andeavor Acquisition

On October 1, 2018, we completed the Andeavor acquisition. Andeavor stockholders received in the aggregate approximately 239.8 million shares of MPC common stock valued at $19.8 billion and approximately $3.5 billion in cash in connection with the Andeavor acquisition.

Andeavor was a highly integrated marketing, logistics and refining company operating primarily in the Western and Mid-Continent United States. Andeavor’s operations included procuring crude oil from its source or from other third parties, transporting the crude oil to one of its 10 refineries, and producing, marketing and distributing refined products. Its marketing system included more than 3,300 stations marketed under multiple well-known fuel brands including ARCO^®. Also, we acquired the general partner and 156 million common units of ANDX, which ~~is a publicly traded limited partnership that~~ was formed to own, operate, develop and acquire logistics assets. Its assets are integral to the success of our refining and marketing operations and are used to gather crude oil, natural gas, and water, process natural gas and distribute, transport and store crude oil and refined products.

This transaction combined two strong, complementary companies to create a leading nationwide U.S. downstream energy company. The acquisition substantially ~~increases~~increased our geographic diversification and scale and ~~strengthens~~strengthened each of our operating segments by diversifying our refining portfolio into attractive markets and increasing access to advantaged feedstocks, enhancing our midstream footprint in the Permian Basin, and creating a nationwide retail and marketing portfolio all of which is expected to substantially improve efficiencies and our ability to serve customers. We expect the combination to generate up to approximately $1.4 billion in gross run-rate synergies within the first three years, significantly enhancing our long-term cash flow generation profile.

~~MPLX and ANDX~~

On February 1, 2018, we contributed refining logistics assets and fuels distribution services to MPLX in exchange for $4.1 billion in cash and approximately 114 million newly issued MPLX units. Immediately following the dropdown, our IDRs were cancelled and our economic general partner interest was converted into a non-economic general partner interest, all in exchange for 275 million newly issued MPLX common units. MPLX financed the cash portion of the February 1, 2018 dropdown with its $4.1 billion 364-day term loan facility, which was entered into on January 2, 2018. On February 8, 2018, MPLX issued $5.5 billion in aggregate principal amount of senior notes in a public offering. MPLX used $4.1 billion of the net proceeds of the offering to repay the 364-day term-loan facility. The remaining proceeds were used to repay outstanding borrowings under MPLX’s revolving credit facility and intercompany loan agreement with us and for general partnership purposes.

MPLX and ANDX

We owned approximately 505 million MPLX common units at June 30, 2019 with a market value of $16.25 billion based on the June 28, 2019 closing price of $32.19 per common unit. On July 22, 2019, MPLX declared a quarterly cash distribution of $0.6675 per common unit payable on August 14, 2019. As a result, MPLX will make distributions totaling $692 million to its common unitholders, which includes $94 million to former ANDX common unitholders. MPC’s portion of these distributions is approximately $431 million.

We owned approximately 156 million ANDX common units at June 30, 2019 with a market value of $5.67 billion based on the June 28, 2019 closing price of $36.33 per common unit. Subsequent to MPLX’s acquisition of ANDX, as previously discussed, ANDX common unitholders will not receive any future distributions from ANDX but instead will receive a second quarter 2019 distribution noted above with respect to the MPLX common units issued in connection with the merger. Additionally, the ANDX Series A Preferred unitholders will not receive any future distributions from ANDX, but instead will receive the semi-annual distribution payable August 15, 2019 on MPLX Series B Preferred units issued in connection with the merger.

The following table summarizes the MPLX distributions we received in the ~~three~~six months ended ~~March 31,~~June 30, 2019 and 2018 and ANDX distributions we received in the ~~three~~six months ended ~~March 31,~~June 30, 2019.

Liquidity

As of ~~March 31,~~June 30, 2019, we had cash and cash equivalents of approximately ~~$755 million,~~$1.22 billion, excluding MPLX and ANDX cash and cash equivalents of ~~$93~~$7 million and ~~$29~~$25 million, respectively, no borrowings and $32 million in letters of credit outstanding under our $6.0 billion bank revolving credit facilities and no borrowings outstanding under our $750 million trade receivables facility, resulting in cash and available liquidity of ~~almost $7.5~~$7.93 billion. As of ~~March 31,~~June 30, 2019, MPLX had approximately ~~$1.82~~$1.63 billion available through its bank revolving credit agreement and ~~$1 billion~~$956 million available through its intercompany credit facility with MPC. As of ~~March 31,~~June 30, 2019, ANDX had approximately ~~$696~~$600 million available through its bank revolving credit agreements and $500 million available through its intercompany credit facility with MPC.

On July 31, 2019, in connection with the closing of the ANDX merger, we amended and restated the existing intercompany loan agreement with MPLX to, among other things, increase MPLX’s borrowing capacity thereunder from $1.0 billion to $1.5 billion in loans at any one time outstanding and to extend the term of the intercompany loan agreement to July 31, 2024.

On July 26, 2019, we entered into a new $1 billion 364-day revolving credit facility with a syndicate of banks that will, subject to the satisfaction of customary conditions, become effective upon the expiration of our existing $1 billion 364-day revolving facility in September 2019. The new 364-day revolving credit facility contains substantially the same terms and conditions as our existing 364-day revolving credit facility and will expire in September 2020.

On July 19, 2019, we amended our $750 million trade receivables securitization facility to extend the maturity date to July 16, 2021.

OVERVIEW OF SEGMENTS

Refining & Marketing

Refining & Marketing segment income from operations depends largely on our Refining & Marketing margin 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 relationship as the cost of crude oil. As a performance benchmark and a comparison with other industry participants, we calculate ~~West~~Gulf Coast, Mid-Continent and ~~Gulf~~West Coast 3-2-1 crack spreads that we believe most closely track our operations and slate of products. The following are used for these crack-spread calculations:

The ~~West~~Gulf Coast crack spread uses three barrels of ~~ANS~~LLS crude producing two barrels of ~~LA CARBOB~~USGC CBOB gasoline and one barrel of ~~LA CARB Diesel;~~

~~Table of Contents~~

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 ~~Gulf~~West Coast crack spread uses three barrels of ~~LLS~~ANS crude producing two barrels of ~~USGC CBOB gasoline~~LA CARBOB and one barrel of ~~USGC ULSD.~~LA CARB Diesel.

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

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

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



(In millions, after-tax)
Blended crack spread sensitivity^(a)(per $1.00/barrel change)	$	900
Sour differential sensitivity^(b) (per $1.00/barrel change)	450
Sweet differential sensitivity^(c) (per $1.00/barrel change)	370
Natural gas price sensitivity^(d) (per $1.00/MMBtu)	300


^(a)	Crack spread based on 38 percent ~~WTI,~~LLS, 38 percent ~~LLS~~WTI and 24 percent ANS with ~~Mid-Continent,~~ 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


^(c)	Sweet crude oil basket consists of the following crudes: Bakken, Brent, LLS, WTI-Cushing and WTI-Midland


^(d)	This is consumption based exposure for our Refining & Marketing segment and does not include ~~the~~ the effects to 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 and the mix of refined products as compared to the assumptions used to calculate the market crack spreads;

the types of crude oil and other charge and blendstocks processed as compared to the assumptions used to calculate the market crack spreads;

our refinery yields;

the cost of products purchased for resale;

the impact of commodity derivative instruments used to hedge price risk; and

the potential impact of LCM adjustments to inventories in periods of declining prices.

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.

Table of Contents

Refining & Marketing segment income from operations is also affected by changes in refinery direct operating costs, which include turnaround and major maintenance, depreciation and amortization and other manufacturing expenses. Changes in manufacturing costs are primarily driven by the cost of energy used by our refineries, including purchased natural gas, and the level of maintenance costs. Planned major maintenance activities, or turnarounds, requiring temporary shutdown of certain refinery operating units, are periodically performed at each refinery. Costs for planned turnaround, major maintenance and engineering projects are expensed in the period incurred.

We have various long-term, fee-based commercial agreements with MPLX and ANDX. Under these agreements, MPLX and ANDX, which are reported in our Midstream segment, provide 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

~~Table of Contents~~

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.

Inventories are carried at the lower of cost or market value. Costs of refined products and merchandise 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.

Midstream

Our Midstream segment transports, stores, distributes and markets crude oil and refined products, principally for our Refining & Marketing segment. The profitability of our pipeline transportation operations primarily depends on tariff rates and the volumes shipped through the pipelines. The profitability of our marine operations primarily depends on the quantity and availability of our vessels and barges. The profitability of our light product terminal operations primarily depends on the throughput volumes at these terminals. The profitability of our fuels distribution services primarily depends on the sales volumes of certain refined products. The profitability of our refining logistics operations depends on the quantity and availability of our refining logistics assets. A majority of the crude oil and refined product shipments on our pipelines and marine vessels and the refined product throughput at our terminals serve our Refining & Marketing segment and our refining logistics assets and fuels distribution services are used solely by our Refining & Marketing segment. As discussed above in the Refining & Marketing section, MPLX and ANDX, which are reported in our Midstream segment, have various long-term, fee-based commercial agreements related to services provided to our Refining & Marketing segment. Under these agreements, MPLX and ANDX have 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.

Table of Contents

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.

RESULTS OF OPERATIONS

The following discussion includes comments and analysis relating to our results of operations. Our results include the results of Andeavor from the October 1, 2018 acquisition date forward. This discussion should be read in conjunction with Item 1. Financial Statements and is intended to provide investors with a reasonable basis for assessing our historical operations, but should not serve as the only criteria for predicting our future performance.

Second Quarter 2019 Compared to Second Quarter 2018

Net income ~~(loss)~~ attributable to MPC ~~decreased $44~~increased $51 million in the ~~first~~second quarter of 2019 compared to the ~~first~~second quarter of 2018 primarily due to an increase in income from operations, ~~more~~partially offset by increases in net interest and other financial costs, net income attributable to noncontrolling interests and provision for income taxes.

Revenues and other income increased $11.24 billion. Sales and other operating revenues increased $11.23 billion primarily due to increased Refining & Marketing segment refined product sales volumes, which increased 1,422 mbpd, largely due to the Andeavor acquisition on October 1, 2018.

Costs and expenses increased $10.91 billion primarily due to:

increased cost of revenues of $10.03 billion mainly due to the inclusion of costs related to the Andeavor operations following the acquisition;

Table of Contents

increased depreciation and amortization of $353 million primarily due to the depreciation of the fair value of assets acquired in connection with the Andeavor acquisition;

increased selling, general and administrative expenses of $480 million largely due to the inclusion of costs related to Andeavor operations and reflecting MPC’s classification of costs and expenses; and

increased other taxes of $52 million primarily due to the inclusion of other taxes related to the acquired Andeavor operations.

Net interest and other financial costs increased $127 million mainly due to debt assumed in the acquisition of Andeavor and increased MPLX borrowings.

Provision for income taxes increased $72 million primarily due to increased income before income taxes of $204 million. The combined federal, state and foreign income tax rate was 21 percent and 19 percent for the three months ended June 30, 2019 and 2018, respectively. The effective tax rate for the three months ended June 30, 2019 was equal to the U.S. statutory rate of 21 percent primarily due to certain permanent tax differences related to net income attributable to noncontrolling interests offset by equity compensation and state and local tax expense. The effective tax rate for the three months ended June 30, 2018 was less than the U.S. statutory rate of 21 percent primarily due to certain permanent tax differences related to net income attributable to noncontrolling interests and equity compensation offset by state and local tax expense.

Net income attributable to noncontrolling interests increased $80 million primarily due to net income attributable to noncontrolling interest in ANDX.

Six Months Ended June 30, 2019 Compared to Six Months Ended June 30, 2018

Net income attributable to MPC increased $7 million in the first six months of 2019 compared to the first six months of 2018 primarily due to an increase in income from operations, partially offset by increases in net interest and other financial costs, provision for income taxes and net income attributable to noncontrolling interests.

~~First Quarter 2019 Compared to First Quarter 2018~~

Revenues and other income increased ~~$9.63~~$20.87 billion primarily due to:

increased sales and other operating revenues of ~~$9.39~~$20.63 billion primarily due to increased Refining & Marketing segment refined product sales volumes, which increased ~~1,408~~1,415 mbpd, largely due to the Andeavor acquisition on October 1, 2018; and

increased net gain on disposal of assets of ~~$212~~$213 million ~~primarily~~ mainly due to a $207 million gain recognized in connection with MPC’s exchange of its undivided interest in the Capline pipeline system for an equity ownership in Capline LLC.

Costs and expenses increased ~~$9.40~~$20.31 billion primarily due to:

increased cost of revenues of ~~$8.39~~$18.48 billion primarily due to the inclusion of costs related to the Andeavor operations following the acquisition;

increased depreciation and amortization of ~~$391~~$744 million ~~primarily~~largely due to the depreciation of the fair value of assets acquired in connection with the Andeavor acquisition;

The following table presents certain benchmark prices in our marketing areas and market indicators that we believe are helpful in understanding the results of our Refining & Marketing segment. Following the acquisition of Andeavor in October 2018, we expanded the benchmark prices included in these tables to include market information for the West Coast region of the United States, including LA CARBOB and LA CARB diesel spot prices, ANS crude prices and a West Coast ANS 3-2-1 crack spread. However, since the results of the Andeavor businesses are only included in our results from October 1, 2018 forward, these market indicators did not affect our results for the second quarter and first ~~quarter~~six months of 2018. The benchmark crack spreads below do not reflect the market cost of RINs necessary to meet EPA renewable volume obligations for attributable products under the Renewable Fuel Standard.

~~First~~Second Quarter 2019 Compared to ~~First~~Second Quarter 2018

Refining & Marketing segment revenues increased ~~$8.40~~$9.98 billion primarily due to higher refined product sales volumes, which increased ~~1,408~~1,422 mbpd mainly due to the Andeavor acquisition on October 1, 2018, partially offset by decreased average refined product sales prices of ~~$0.08~~$0.07 per gallon.

Refinery crude oil capacity utilization was 97 percent during the second quarter of 2019 and total refinery throughputs increased 1,097 mbpd primarily due to the refineries acquired from Andeavor.

Refining & Marketing segment ~~loss~~income from operations ~~increased $201~~decreased $119 million primarily driven by ~~narrower crude discounts across our medium~~higher Refining & Marketing margin, which was more than offset by higher operating, distribution and ~~heavy crude slate. Additionally, high industry gasoline inventories~~planned turnaround costs as well as higher depreciation and amortization. The increases in Refining & Marketing margin and costs and expenses were primarily due to increased sales and production volumes following the ~~fourth quarter’s strong production environment resulted in weaker gasoline margins particularly in January~~Andeavor acquisition.

Refining & Marketing margin was $15.24 per barrel for the second quarter of ~~2019.~~

~~Based on~~2019 compared to $15.40 per barrel for the ~~changes in~~second quarter of 2018. Refining & Marketing margin is affected by the market indicators shown ~~above,~~earlier, which use spot market values and an estimated mix of crude purchases and product ~~sales,~~sales. Based on the market indicators and our crude oil throughput, we estimate a net positive impact of ~~$1.41~~approximately $2.1 billion on Refining & Marketing margin for the second quarter of 2019 compared to the second quarter of 2018, primarily due to an approximate $2.0 billion benefit from increased throughput volume, mainly attributed to the Andeavor acquisition, partially offset by narrower crude oil differentials. Our reported Refining & Marketing margin differs from market indicators due to the mix of crudes purchased and their costs, the

effect of market structure on our crude oil acquisition prices, the effect of RIN prices on the crack spread, and other items like refinery yields and other feedstock variances. These factors had an estimated negative effect of $600 million on Refining & Marketing segment income in the second quarter of 2019 compared to the second quarter of 2018.

Refining operating costs, excluding depreciation and amortization, increased $1.16 per barrel, refining planned turnaround costs increased $0.50 per barrel and distribution costs, excluding depreciation and amortization, increased $0.31 per barrel. All of these increases were primarily due to the inclusion of costs for the refining operations acquired from Andeavor and the timing of turnaround activity. The per barrel cost increases, among other items, reflect the addition of Andeavor’s West Coast refineries, which generally have higher operating costs than the other regions in which we operate due to specific geographical location and regulatory factors. Distribution costs, excluding depreciation and amortization, include fees paid to MPLX and ANDX of $798 million and $596 million for the second quarter of 2019 and 2018, respectively. Depreciation and amortization per barrel increased by $0.08, primarily due to the $0.07 increase for intangible asset amortization related to the fair value of assets acquired from Andeavor as of October 1, 2018.

Six Months Ended June 30, 2019 Compared to Six Months Ended June 30, 2018

Refining & Marketing segment revenues increased $18.38 billion primarily due to higher refined product sales volumes, which increased 1,415 mbpd mainly due to the Andeavor acquisition on October 1, 2018, partially offset by decreased average refined product sales prices of $0.07 per gallon.

Refinery crude oil capacity utilization was 96 percent in the first six months of 2019 and total refinery throughputs increased 1,137 mbpd primarily due to the refineries acquired from Andeavor.

Refining & Marketing segment income from operations ~~largely~~decreased $320 million primarily driven by higher Refining & Marketing margin, more than offset by higher operating, distribution, planned turnaround and depreciation costs. The increases in Refining & Marketing margin and operating, distribution, planned turnaround and depreciation costs are primarily due to increased sales and production volumes following the Andeavor acquisition.

Refining & Marketing margin was $13.23 per barrel for the first six months 2019 compared to $13.08 per barrel for the first six months of 2018. 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 ~~$1.54~~net positive impact of approximately $3.5 billion on Refining & Marketing margin for the first six months of 2019 compared to the first six months of 2018, primarily due to an approximate $3.2 billion benefit from ~~increases in sales volume. Differences in our results compared~~increased throughput volume, mainly attributed to ~~these~~the Andeavor acquisition, and wider sweet crude oil differentials, partially offset by narrowing sour crude oil differentials.Our reported Refining & Marketing margin differs from market indicators ~~including the effects of product price realizations,~~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,~~variances.

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 ~~its~~their most comparable GAAP financial ~~measure,~~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:

Net cash used in investing activities increased ~~$742 million~~$1.36 billion in the first ~~three~~six months of 2019 compared to the first ~~three~~six months of 2018, primarily due to the following:

An increase in additions to property, plant and equipment of ~~$486~~$953 million primarily due to increased capital expenditures in the first ~~three~~six months of 2019 in our Midstream and Refining & Marketing segments; and

an increase in net investments of ~~$282~~$434 million largely due to investments in connection with the construction of the Gray Oak Pipeline, which is scheduled to commence operations in the fourth quarter of 2019.

Cash used in dividend payments increased ~~$135~~$276 million in the first ~~three~~six months of 2019 compared to the first ~~three~~six months of 2018, primarily due to a net increase in the number of shares of our common stock outstanding related to the Andeavor acquisition and a ~~$0.07~~$0.14 per share increase in our base dividend, partially offset by a reduction of shares resulting from share repurchases. Our dividend payments were ~~$0.53~~$1.06 per common share in the first ~~three~~six months of 2019 compared to ~~$0.46~~$0.92 per common share in the first ~~three~~six months of 2018.

On July 26, 2019, we entered into a new $1 billion 364-day revolving credit facility with a syndicate of banks that will, subject to the satisfaction of customary conditions, become effective upon the expiration of our existing $1 billion 364-day revolving facility in September 2019. The new 364-day revolving credit facility contains substantially the same terms and conditions as our existing 364-day revolving credit facility and will expire in September 2020.

On July 19, 2019, we amended our $750 million trade receivables securitization facility to extend the maturity date to July 16, 2021.

We have a commercial paper program that allows us to have a maximum of $2.0 billion in commercial paper outstanding. We do not intend to have outstanding commercial paper borrowings in excess of available capacity under our bank revolving credit facility. As of ~~March 31,~~June 30, 2019, we had no commercial paper borrowings outstanding.

See Note 17 to the unaudited consolidated financial statements for further discussion of our debt.

The MPC credit agreements contain representations and warranties, affirmative and negative covenants and events of default that we consider usual and customary for agreements of these types. The financial covenant included in the MPC credit agreements requires us to maintain, as of the last day of each fiscal quarter, a ratio of Consolidated Net Debt to Total Capitalization (as defined in the MPC credit agreements) of no greater than 0.65 to 1.00. As of ~~March 31,~~June 30, 2019, we were in compliance with this financial covenant, with a ratio of Consolidated Net Debt to Total Capitalization of ~~0.22~~0.21 to 1.00, as well as the other covenants contained in the MPC bank revolving credit facility.

The MPLX credit agreement contains representations and warranties, affirmative and negative covenants and events of default that we consider usual and customary for agreements of these types. The MPLX credit agreement includes a financial covenant that requires MPLX to maintain a ratio of Consolidated Total Debt (as defined in the MPLX credit agreement) as of the end of each fiscal quarter to Consolidated EBITDA (as defined in the MPLX credit agreement) for the prior four fiscal quarters of not greater than 5.0 to 1.0 (or 5.5 to 1.0 during the six-month period following certain acquisitions). Consolidated EBITDA is subject to adjustments for certain acquisitions completed and capital projects undertaken during the relevant period. Other covenants restrict MPLX and/or certain of its subsidiaries from incurring debt, creating liens on assets and entering into transactions with affiliates. As of ~~March 31,~~June 30, 2019, MPLX was in compliance with this debt covenant, with a ratio of Consolidated Total Debt to Consolidated EBITDA of ~~3.85~~3.70 to 1.0, as well as the other covenants contained in the MPLX credit agreement.

The ANDX credit agreements 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, including a financial covenant that requires ANDX to maintain a Consolidated Leverage Ratio (as defined in the ANDX credit agreements) for the prior four fiscal quarters of no greater than 5.0 to 1.0 (or 5.5 to 1.0 for up to two fiscal quarters following certain acquisitions). Consolidated EBITDA used to calculate the Consolidated Leverage Ratio is subject to adjustments for certain acquisitions completed and capital projects undertaken during the relevant period. The covenants also restrict, among other things, ANDX’s ability and/or the ability of certain of its subsidiaries to incur debt, create liens on assets and enter into transactions with affiliates. As of March 31, 2019, ANDX was in compliance with this debt covenant, with a Consolidated Leverage Ratio of 3.86 to 1.0, as well as the other covenants contained in the ANDX credit agreements.

Our intention is to maintain an investment-grade credit profile. As of ~~March 31,~~July 30, 2019, the credit ratings on our senior unsecured debt were as follows.



Company	Rating Agency	Rating
MPC	Moody’s	Baa2 (stable outlook)
	Standard & Poor’s	BBB (stable outlook)
	Fitch	BBB (stable outlook)
MPLX	Moody’s	~~Baa3~~Baa2 (stable outlook)
	Standard & Poor’s	BBB (stable outlook)

~~ANDX~~	~~Moody’s~~	~~Ba1 (review for upgrade)~~
	~~Standard & Poor’s~~	~~BBB- (positive watch)~~
	~~Fitch~~	~~BBB-~~BBB (stable outlook)

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

None of the MPC credit agreements, the MPLX credit agreement, ~~the ANDX 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. 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.~~agreements and make it more difficult to raise capital in the future.

This 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 2019, excluding capitalized interest and acquisitions, includes $2.2 billion of organic growth capital and approximately $200 million of maintenance capital. ANDX’s capital investment plan for 2019, excluding capitalized interest and acquisitions, includes $600 million of organic growth capital and approximately $100 million of maintenance capital. We continuously evaluate our capital investment plan and make changes as conditions warrant.

Capital expenditures and investments are summarized by segment below. These amounts include capital spending and investments related to businesses acquired in connection with the Andeavor acquisition from October 1, 2018 forward.

The Midstream segment capital investment plan includes projects for MPLX and ANDX. MPLX’s capital investment plan includes the addition of approximately 825 MMcf/d of processing capacity at five gas processing plants, two in the Marcellus and three in the Southwest, which expands MPLX’s processing capacity in the Permian Basin and the STACK shale play of Oklahoma. The MPLX capital investment plan also includes the addition of approximately 100 mbpd of fractionation capacity in the Marcellus and Utica basins and the continued expansion of MPLX’s marine fleet, long-haul crude

oil, natural gas and NGL pipelines as well as projects to increase its export capability. The ANDX capital investment plan includes the construction of additional crude storage capacity for unloading of marine vessels, the construction of crude gathering systems to provide connectivity to multiple long-haul pipelines and a pipeline interconnect project to provide direct connectivity between certain MPC refineries. The remaining Midstreamsegment’s capital ~~expenditure projects~~expenditures and investments relate to investments in equity affiliate pipelines, including our expected investments in the Gray Oak Pipeline, a new pipeline spanning from the West Texas Permian Basin to the Gulf Coast which is expected to be in service by the end of 2019.

The Refining & Marketing segment capital investment plan includes projects focused on high-return investments in refinery optimization, production of higher value products, increased capacity to upgrade residual fuel oil and expanded export capacity. We also plan to continue investing in domestic light products supply placement flexibility.

Other Capital Requirements

During the ~~three~~six months ended ~~March 31,~~June 30, 2019, we ~~made no contributions~~contributed $16 million to our funded pension plans ~~however, we~~and have additional required funding for the 2019 plan year of approximately ~~$64 million and we~~$48 million. We may choose to make additional contributions to our pension plans.

On ~~April 24,~~July 31, 2019, our board of directors approved a dividend of $0.53 per share on common stock. The dividend is payable ~~June~~September 10, 2019, to shareholders of record as of the close of business on ~~May 16,~~August 21, 2019.

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

Share Repurchases

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 ~~$13.98~~$14.48 billion of our common stock, leaving ~~$4.02~~$3.52 billion available for repurchases at ~~March 31,~~June 30, 2019. The table below summarizes our total share repurchases for the ~~three~~six months ended ~~March 31,~~June 30, 2019 and 2018. 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, accelerated share repurchases or open market solicitations for shares, some of which may be effected through Rule 10b5-1 plans. The timing and amount of future repurchases, if any, will depend upon several factors, including market and business conditions, and such repurchases may be discontinued at any time.

Contractual Cash Obligations

As of ~~March 31,~~June 30, 2019, our contractual cash obligations included long-term debt, capital and operating lease obligations, purchase obligations and other long-term liabilities. During the first ~~three~~six months of 2019, our long-term debt commitments decreased approximately ~~$230~~$550 million due to interest payments made during the ~~quarter~~period, partially offset by increased borrowings on the MPLX bank revolving credit ~~facility and ANDX bank revolving credit facilities.~~facility.

There were no other material changes to our contractual cash obligations outside the ordinary course of business since December 31, 2018.

~~Table of Contents~~

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 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 2423 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.

On March 3, 2014, the EPA signed the final Tier 3 fuel standards. The final Tier 3 fuel standards require, among other things, a lower annual average sulfur level in gasoline to no more than 10 ppm beginning in calendar year 2017. In addition, gasoline refiners and importers may not exceed a maximum per-gallon sulfur standard of 80 ppm while retailers may not exceed a maximum per-gallon sulfur standard of 95 ppm. From 2014 through 2018, we made approximately $490 million in capital expenditures to comply with these standards and expect to make approximately ~~$260~~$245 million in capital expenditures for these standards in 2019.

There have been no significant changes to our environmental matters and compliance costs during the ~~three~~six months ended ~~March 31,~~June 30, 2019.

CRITICAL ACCOUNTING ESTIMATES

As of ~~March 31,~~June 30, 2019, 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, 2018.

ACCOUNTING STANDARDS NOT YET ADOPTED

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

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

For a detailed discussion of our risk management strategies and our derivative instruments, see Item 7A. Quantitative and Qualitative Disclosures about Market Risk in our Annual Report on Form 10-K for the year ended December 31, 2018.

See Notes 15 and 16 to the unaudited consolidated financial statements for more information about the fair value measurement of our derivatives, as well as the amounts recorded in our consolidated balance sheets and statements of income. We do not designate any of our commodity derivative instruments as hedges for accounting purposes.

The following table includes the composition of net losses on our commodity derivative positions as of ~~March 31,~~June 30, 2019 and 2018, respectively.


		Three Months Ended March 31,							Six Months Ended June 30,

See Note 16 to the unaudited consolidated financial statements for additional information on our open derivative positions at ~~March 31,~~June 30, 2019.

Sensitivity analysis of the effects on income from operations (“IFO”) of hypothetical 10 percent and 25 percent increases and decreases in commodity prices for open commodity derivative instruments as of ~~March 31,~~June 30, 2019 is provided in the following table.


		Change in IFO from a Hypothetical Price Increase of						Change in IFO from a Hypothetical Price Decrease of							Change in IFO from a Hypothetical Price Increase of						Change in IFO from a Hypothetical Price Decrease of

Embedded derivatives	Embedded derivatives	(7		)	(16		)	7			16			Embedded derivatives	(7		)	(16		)	7			16

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

We evaluate our portfolio of commodity derivative instruments on an ongoing basis and add or revise strategies in anticipation of changes in market conditions and in risk profiles. Changes to the portfolio after ~~March 31,~~June 30, 2019 would cause future IFO effects to differ from those presented above.

Sensitivity analysis of the effect of a hypothetical 100-basis-point change in interest rates on long-term debt, including the portion classified as current and excluding finance leases, as of ~~March 31,~~June 30, 2019 is provided in the following table. Fair value of cash and cash equivalents, receivables, accounts payable and accrued interest approximate carrying value and are relatively insensitive to changes in interest rates due to the short-term maturity of the instruments. Accordingly, these instruments are excluded from the table.

Table of Contents

At ~~March 31,~~June 30, 2019, 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 ~~13(a)-15(e)~~13a-15(e) under the Securities Exchange Act of 1934, as amended) was carried out under the supervision and with the participation of our management, including our chief executive officer and chief financial officer. Based upon that evaluation, the chief executive officer and chief financial officer concluded that the design and operation of these disclosure controls and procedures were effective as of ~~March 31,~~June 30, 2019, the end of the period covered by this report.

Internal Control over Financial Reporting and Changes in Internal Control over Financial Reporting

During the quarter ended ~~March 31,~~June 30, 2019, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are the subject of, or a party to, a number of pending or threatened legal actions, contingencies and commitments involving

a variety of matters, including laws and regulations relating to the environment. Except as described below, there have been no material changes to the legal proceedings previously disclosed in our Annual Report on Form 10-K, as updated in the Quarterly Report on Form 10-Q for the quarter ended March 31, 2019.

Litigation

As previously disclosed, in May 2007, the Kentucky attorney general filed a lawsuit against us and Marathon Oil in state court in Franklin County, Kentucky for alleged violations of Kentucky’s emergency pricing and consumer protection laws following Hurricanes Katrina and Rita in 2005. The lawsuit alleged that we overcharged customers by $89 million during September and October 2005. The complaint sought disgorgement of these sums, as well as penalties, under Kentucky’s emergency pricing and consumer protection laws. In May 2011, the Kentucky attorney general amended his complaint to include a request for immediate injunctive relief as well as unspecified damages and penalties related to our wholesale gasoline pricing in April and May 2011 under statewide price controls that were activated by the Kentucky governor on April 26, 2011 and which have since expired. The court denied the attorney general’s request for immediate injunctive relief. In July 2019, MPC and the attorney general reached a settlement to resolve this litigation. This resolution will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Environmental Proceedings

Detroit Refinery

In June 2019, we received an offer from the ~~first quarter~~Michigan Department of ~~2019, MPLX entered into an agreement~~Environment, Great Lakes, and Energy (“EGLE”) to settle ~~notices~~violations alleged in five NOVs issued to the refinery between September 2017 and February 2019. The NOVs allege violations of ~~violation~~emissions limitations and other requirements of the refinery’s air permit. We are negotiating a settlement of the allegations with EGLE and cannot currently estimate the timing of the resolution of this matter.

El Paso Refinery

We are presently negotiating with the EPA regarding several emission events at our El Paso refinery that could subject the refinery to stipulated penalties under the existing Consent Decree in U.S. v. Western Refining Co. LP, W.D. Texas No. 3:11-CV-00276-FM (entered August 31, 2011). We cannot currently estimate the timing of the resolution of this matter.

Gallup Refinery

As previously disclosed in MPC’s Annual Report on Form 10-K for the year ended December 31, 2018 (the “2018 10-K”), on October 19, 2018, Western Refining Southwest, Inc. (“Refining Southwest”) received an offer from the ~~West Virginia Department~~EPA to settle alleged violations of ~~Environmental Protection relating to earth disturbance activities in connection with construction of an NGL line. The $124,030 penalty payment is expected to be made in~~the Resource Conservation and Recovery Act (“RCRA”) regulations. In the second quarter of 2019, Refining Southwest and the EPA executed a Consent Agreement and Final Order (CAFO) (Effective Date April 3, 2019) to resolve these allegations, which arose from the Gallup refinery’s self-disclosure of incorrectly profiling and shipping hazardous waste between August 26, 2013 and February 18, 2014 to a disposal site that did not have a RCRA permit and could not accept RCRA hazardous waste. The CAFO requires payment of a penalty of $148,303, and the development of a standard operating procedure, training, a system of management review of waste determination, and a narrative of changes since the alleged violations occurred.

As previously disclosed in our 2018 10-K, in March 2016, the EPA conducted a Risk Management Program inspection at our Gallup refinery and issued an Inspection Report on April 7, 2016 identifying Areas of Concern. In the second quarter of 2019, Refining Southwest and the EPA executed a Consent Agreement and Final Order (CAFO) and Administrative Compliance Order (ACO) (Effective Date April 16, 2019) to resolve alleged violations of the Clean Air Act regulations at the Gallup refinery arising from a Risk Management Program (RMP) inspection that EPA conducted at Gallup refinery in March 2016. Pursuant to the CAFO & ACO Gallup paid a civil penalty of $98,874 and will complete a Supplemental Environmental Project (SEP) valued at approximately $91,351.

Galveston Bay Refinery

In the second quarter of 2019, we reached an agreement with the Texas Commission on Environmental Quality to pay a penalty of $62,782 and undertake a supplemental environmental project at a cost of $62,781 to settle allegations arising from an investigation of deviations self-reported in the 2016 Title V deviation reports.

Table of Contents

Los Angeles Refinery

As previously disclosed in our 2018 10-K, Tesoro Refining and Marketing LLC (“TRMC”) previously reached an agreement in principle to pay a penalty of $425,000 and undertake a supplemental environmental project at a cost of $425,000 to settle allegations by the CARB relating to the state’s Greenhouse Gas Reporting Standards. The CARB allegations relate to the self-disclosure and correction of reported greenhouse gas emissions emitted by the Los Angeles refinery’s calciner unit from May 9, 2014 to June 12, 2017. A formal agreement consistent with the foregoing was signed in May 2019, and we expect to make the related payments in the third quarter of 2019.

As previously disclosed in our 2018 10-K, TRMC reached an agreement to pay a penalty of $75,000 and undertake certain supplemental environmental projects with an estimated cost of $75,000 to settle five NOVs from the South Coast Air Quality Management District. The NOVs were issued to the Los Angeles refinery between June and October 2017, alleging violations of various federal and district air emission regulations. A formal agreement consistent with the foregoing was signed in April 2019 and the penalty has been paid.

Martinez Refinery

As previously disclosed in our 2018 10-K, on July 18, 2016, the U.S. Department of Justice (“DOJ”) lodged a complaint on behalf of the EPA and a Consent Decree with the Western District Court of Texas. Among other things, the Consent Decree required that the Martinez refinery meet certain annual emission limits for NOx by July 1, 2018. In February 2018, TRMC informed the EPA that it would need additional time to satisfy requirements of the Consent Decree. In the second quarter of 2019, MPC, the EPA and the DOJ reached a settlement in principle, which includes a civil penalty of approximately $6.5 million and a schedule for installation of a Selective Catalytic Reduction system to control NOx emissions from the FCCU.

ITEM 1A. RISK FACTORS

There have been no material changes from the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2018, ~~other than the risks described below related to the pending MLP Merger.~~

The pending merger between MPLX and ANDX (the “MLP Merger”) 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 MLP merger could have a material and adverse effect on us and, even if completed, the MLP merger may not achieve some or all of the anticipated benefits.

~~On May 8, 2019, we, together with MPLX and ANDX, announced the MLP Merger. Completion of the MLP Merger is subject to a number of customary conditions set forth~~as updated in ~~the MLP Merger Agreement, including approval by a majority of ANDX’s unitholders, MPLX’s registration statement~~our Quarterly Report on Form ~~S-4 having become effective under~~10-Q for the Securities Act of 1933, the approval to list MPLX units issuable in connection with the MLP Merger on the New York Stock Exchange, the absence of any governmental order or law prohibiting the consummation of the MLP Merger, the accuracy of each party’s representations and warranties under the MLP Merger Agreement (subject to the materiality standards set forth in the MLP Merger Agreement), MPLX’s and ANDX’s performance of their respective obligations under the MLP Merger Agreement in all material respects, and the receipt by both parties from their respective counsels of a written opinion regarding the U.S. federal income tax treatment of the transaction. These and other conditions to the closing of the MLP Merger may not be fulfilled in a timely manner or at all, and, accordingly, the MLP Merger may be delayed or may not be completed.

If the MLP Merger is not completed, our ongoing businesses may be adversely affected and, without realizing any of the benefits of having completed the MLP Merger, we will be subject to a number of risks, including the following:

~~we will be required to pay our costs relating to the MLP Merger, such as legal, accounting and financial advisory expenses, whether or not MLP Merger is completed;~~

~~time and resources committed by our management to matters relating to MLP Merger could otherwise have been devoted to pursuing other beneficial opportunities; and~~

~~the market price of our common stock could decline to the extent that the current market price reflects a market assumption that the MLP Merger will be completed.~~

~~In addition, even if completed there can be no assurance that the MLP Merger will deliver the strategic, financial and operational benefits anticipated by us.~~quarter ended March 31, 2019.

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

The following table sets forth a summary of our purchases during the quarter ended ~~March 31,~~June 30, 2019, of equity securities that are registered by MPC pursuant to Section 12 of the Securities Exchange Act of 1934, as amended.
