FROM THE PRESIDENT AND CEO

Fellow Shareholders,

2020 was a pivotal year for Marathon as we began a process to  
transform the company, lowering our cost structure and shaping  
our asset portfolio amid evolving stakeholder expectations and  
opportunities created by the energy evolution. While these efforts 
continue through 2021, we made significant progress during the year.

Despite the demands of COVID-19, our teams remained focused  
on our core values and on their central mission. As a result, we set  
a new industry benchmark for certifications in the EPA’s ENERGY 
STAR® program and achieved significant improvements over 2019 
in our process safety and environmental performance.

Complemented by our ongoing sustainability focus, which inspired 
us to take industry-leading actions, our efforts collectively served to 
enhance the company’s competitiveness and longevity amid shifting 
market dynamics. 

Our humanitarian and operational responses to the COVID-19  
pandemic reflected our broader vision of sustainability, which  
emphasizes delivering essential energy products and services to the 
world in ways that create shared value for all our stakeholders – our 
people, business partners, customers, communities, governments 
and shareholders. We deployed more than 500,000 N95 respirator 
masks to frontline healthcare workers in our local communities and 
increased our employee giving match from 60% to 100%. The Marathon 
Petroleum Foundation also donated $1 million to the American Red 
Cross to supply critical resources. 

Building Resiliency – Our Strategic Initiatives

We quickly began implementing actions to strengthen the competitive 
position of our assets, improve our commercial performance and 
lower our cost structure. We made significant moves in our portfolio 
in 2020, which included:

•   Reaching an agreement with 7-Eleven for the pending sale of our 
Speedway retail business for $21 billion, which will help strengthen 
our balance sheet and return capital to MPC shareholders.

•   Beginning production at our Dickinson, North Dakota, renewable 
diesel facility, which is the second largest facility of its kind in the 
United States, designed to produce approximately 180 million 
gallons per year. This facility is anticipated to reach its full rate of 
production by the end of the first quarter of 2021.

•   Moving forward with engineering and permitting efforts on a  

project to convert our idled Martinez, California, refinery to a facility 
that produces renewable transportation fuels. It is anticipated this  
project would be commissioned in 2022 and eventually reach a  
production capacity of approximately 730 million gallons per year.

FROM THE PRESIDENT AND CEO

•   Advancing several midstream projects that support the goal of 

developing long-haul pipelines, including the Wink to Webster crude 
oil pipeline, the Whistler natural gas pipeline and the reversal of the 
Capline crude pipeline.

•   Invested to expand our natural gas processing and fractionation  

assets in the Marcellus and Permian basins, our long-term strategic 
focus areas.

•   Divested or announced plans to divest less strategic assets such  
as the Javelina processing facility and several asphalt terminals.

To improve our commercial performance:

•   We are leveraging our proximity to key supply sources and demand 
hubs, so we can capture higher margins across the value chain. 

•   We aim to maximize value by enhancing raw material selection in 

our refining segment and improving product placement. 

•   In midstream, we are working to grow our fee-based services 
through long-term contracts to provide through-cycle cash  
flow stability. 

In 2020, our midstream segment, which includes MPLX, earned  
$3.7 billion in income from operations, a $113 million increase from the 
year before.

To lower our overall cost structure, our 2020 initiatives included:

•   Indefinitely idling two higher-cost refineries and advancing plans to 

convert one of them to renewable fuel production.

•   Reducing our capital spending levels by more than $1.4 billion from 

our initial plans for MPC and MPLX.

•   Reducing our refining operating expenses by more than $1 billion 
and our midstream operating expenses by more than $200 million.

•   Applying strict cost management practices to reduce our overall 

corporate costs.

Additionally, our 2021 capital spending outlook, excluding MPLX, is 
approximately $350 million less than 2020’s total.

Sustainability - Focused on the Future  
The goals of our strategic initiatives complement and further enable 
our commitment to sustainability, which spans the environmental,  
social and governance (ESG) dimensions of our operations. In 2020, 
we strengthened our efforts to lower our carbon intensity and  
produce a range of fuels that meet the needs of evolving and  
emerging consumer demands, consistent with our principles for  
Leading in Sustainable Energy. These principles correspond with  
several of our most substantial 2020 achievements:

2  

•   Becoming the first independent U.S. refiner to create a company-

wide goal for reducing greenhouse gas emissions intensity and link 
it to employee and executive compensation.

•   Becoming the first-ever petroleum refiner to have five refineries 

earn ENERGY STAR® certifications in one year.

•   Establishing a program to lower methane emissions at our natural 
gas gathering and processing assets that included an intensity  
reduction target, as well as becoming one of the first companies 
to launch a program to track and reduce freshwater withdrawal 
intensity across all our refineries.

We made a significant shift and have designated $350 million  
in capital spending for renewable projects in 2021, representing  
25% of our capital budget, excluding MPLX, and a substantial portion  
of our incremental growth capital for the year.

In 2020, we also had several accomplishments in the areas of social 
and governance, including a new Human Rights Policy incorporated 
in our sustainability reporting, increased participation in our Diversity 
& Inclusion programs, comprehensive stakeholder engagement plans 
for all major assets and sustainability performance linked to compen-
sation. These efforts contributed to MPC earning high scores from 
ESG rating organizations that are monitored by institutional investment 
firms. Our scores led to several recognitions, such as placement on 
the Dow Jones Sustainability Index and the Forbes JUST 100. Our 
comprehensive sustainability framework helps to differentiate us and 
provides us with the flexibility to accommodate a variety of emerging 
topics and marketplace demands.

As we look ahead in 2021, the availability of COVID-19 vaccines  
provides hope for the return of global transportation fuel demand 
and economic recovery. Even though many uncertainties still exist, 
the world’s need for reliable, affordable and responsibly produced 
energy remains important. We believe we can continue to meet this 
need through our strategies that will allow us to successfully adapt  
to the evolving energy landscape.

Sincerely,

Michael J. Hennigan  
President and Chief Executive Officer

CORE VALUES

Our values guide the way we treat each other and all our stakeholders.  
We believe our behaviors are just as important as what we do. 

Safety and Environmental Stewardship 
Protecting our people and the world we all share is a priority to  
MPC. We are committed to safe and environmentally responsible  
operations to protect the health and safety of our employees,  
contractors and communities. This commitment is reflected in our 
safety systems design, our well-maintained equipment and our  
focus on continuous learning and improvement.

Integrity 
Integrity at MPC is more than the business conduct policies and  
procedures we follow. We set high expectations for ourselves and 
build trust in each other, with business partners, shareholders and  
the communities where we work and live. We say what we’re going  
to do — and then do it.

Respect 
Respect is built upon the principle that every one of us is valuable  
and contributes toward achieving our vision. We treat everyone  
professionally, with courtesy, honesty and trust. We consider how  
other people’s ideas can improve what we do, and we encourage  
everyone to openly share their perspectives, ideas and concerns.

Inclusion 
We value diversity in culture, background, perspective and experiences. 
We strive to provide our employees with a collaborative, supportive 
and inclusive work environment where they can maximize their  
full potential for personal and business success. This happens when  
our employees, contractors and other stakeholders feel valued  
themselves and value others for who they are.

Collaboration 
We are a company of driven, accomplished professionals who are 
more than the sum of their training and experience. We actively  
partner with our communities, governments and business partners  
to find and create shared value, making a positive difference  
together. We foster constructive, solution-oriented dialogues;  
we genuinely listen to one another and seek out perspectives  
different from our own.

SUSTAINABILITY

Social Responsibility

Our approach to sustainability encompasses our commitment to  
creating shared value with our many stakeholders - empowering  
people to achieve more, contributing to progress in our communities 
and protecting the environment we all share. We report annually on 
our sustainability goals, initiatives and performance in alignment  
with the Sustainability Accounting Standards Board (SASB) and 
Taskforce for Climate-related Financial Disclosures (TCFD) through 
our Sustainability Report and Perspectives on Climate-Related  
Scenarios report.

COVID-19 Response 
MPC deployed more than 500,000 N95 respirator masks to 45 health 
care organizations across 20 states. We also increased our employee 
giving match from 60% to 100%. Additionally, the Marathon Petroleum 
Foundation donated $1 million to the American Red Cross to help 
supply critical resources for disaster relief and support. 

Diversity and Inclusion 
We have a dedicated Diversity and Inclusion (D&I) Office to manage 
our companywide D&I strategy, which incorporates three pillars: 
building awareness, increasing representation and ensuring success. 
As an element of our D&I strategy, Employee Networks serve six 
employee populations – Asian, Black, Hispanic, Veterans, Women 
and LGBTQ+ – and each network has an executive sponsor. We  
increased to approximately 60 Employee Network chapters across 
the company, providing opportunities for meaningful connections 
and support. In 2020 and 2021, MPC achieved a Human Rights 
Campaign Foundation’s Corporate Equality Index score of 100,  
the highest possible score. 

Stakeholder Engagement Plans  
Stakeholder engagement plans are in place for 100% of our major 
assets. These plans help MPC leaders and teams engage stakeholders 
in open dialogue to understand needs and concerns, define priorities, 
identify resources and pursue shared goals. Our stakeholder  
engagement is further strengthened by our commitment to partnering 
and investing in communities through grants, as well as giving and  
volunteerism by our team members. In 2020, our community  
investment through the MPC Foundation, corporate charitable  
contributions and employee giving matched by the company  
totaled more than $16 million.

SUSTAINABILITY

Leading in Sustainable Energy 

Our principles for Leading in Sustainable Energy guide our efforts in continuing to meet the world’s 
energy needs while enhancing our environmental stewardship, including real and quantifiable  
reductions in carbon emissions over time.

Lower Carbon Intensity 
•   Lower the carbon intensity of our operations and the products we process 
•   Improve the energy efficiency of our operations 
•   Work with others to improve energy efficiency within the manufacturing, consumer and  

transportation sectors

Expand Renewable Fuels and Advanced Technologies
•  Increase the volume of renewable fuels we produce and market 
•  Seek ways to expand the use of renewable energy in our operations 
•   Innovate and deploy advanced technologies that reduce environmental impact while  

enhancing business performance

Conserve Natural Resources
•  Advance practices and investments that conserve natural resources
•  Reduce waste generated by our operations
•  Reduce freshwater withdrawal intensity in our refining operations 

The following targets, achievements and activities serve as proof points for our commitment to 
executing on our principled sustainability approach. 

Emissions Targets
•   Greenhouse gas (GHG) emissions intensity: reduce Scope 1 and 2 GHG emissions per barrel-of- 
oil-equivalent (BOE) processed to 30% below 2014 levels by 2030, and link annual progress to 
employee and executive compensation programs.

•   Focus on Methane program: lower methane emissions across our natural gas gathering and  

processing assets, decreasing emissions intensity to 50% below 2016 levels by 2025.

SUSTAINABILITY

Leading in Sustainable Energy 

Energy Efficiency
•   In 2020, we became the first petroleum refiner ever to have five refineries receive  

ENERGY STAR® certifications in one year. Additionally, we were the only petroleum refiner  
to earn the ENERGY STAR® Partner of the Year – Sustained Excellence Award.

•    In the past decade, our Focus on Energy program helped us avoid the equivalent of 1.8 billion 
Btu/hr of energy use or roughly the same amount of energy used by about 100,000 homes. 
The program’s cost savings are approximately $500 million. 

Renewable Fuels and Technologies
•   Our Dickinson, North Dakota, renewable diesel facility is the second largest facility of its  

kind in the United States, designed to produce approximately 180 million gallons per year.  
It makes renewable diesel from corn and soybean oils and is expected to reach its full rate of 
production by the end of the first quarter of 2021. 

•   Progress continues on plans to convert our Martinez, California, refinery into a facility that 

produces renewable fuels from lower carbon-intensity renewable feedstocks with an eventual 
capacity of approximately 730 million gallons per year. Pending the completion of engineering 
and permitting activities, commissioning is expected in 2022 with a potential build to full 
capacity in 2023. 

•   Our Cincinnati biodiesel facility produced more than 80 million gallons of biodiesel in 2020. 
We also blended approximately 84 million gallons of biodiesel into the diesel fuel that we 
marketed and sold in 2020.

•   The joint venture between MPC and The Andersons produced more than 435 million gallons 
of ethanol in 2020 across four plants, including one in Greenville, Ohio. We also blended more 
than 1.8 billion gallons of ethanol into the gasoline that we marketed and sold in 2020.  

•     Virent, a wholly-owned subsidiary of MPC in Madison, Wisconsin, is working to commercialize 
its BioForming® process, which converts biobased feedstocks, such as sugars, into renewable 
fuel. Virent operates a demonstration plant that generates data as part of moving its patented 
technology forward.

Safety and Environmental Stewardship 

As core values, safety and environmental stewardship shape how we approach and execute 
every task across our facilities. In 2020, our dedicated teams demonstrated strong safety and 
environmental performance, including a nearly 40% reduction in severe process safety events 
over 2019 and a 40% reduction in designated environmental incidents over 2019. Our personal 
safety performance continues to trend below the U.S. Refining Average.

PART I

ITEM 1. BUSINESS

OVERVIEW

Marathon Petroleum Corporation (“MPC”) has over 130 years of experience in the energy business, and is 
the largest independent petroleum product refining, marketing, retail and midstream business in the United 
States.  We  operate  the  nation's  largest  refining  system  with  approximately  2.9  million  barrels  per  day  of 
crude  oil  refining  capacity  and  believe  we  are  one  of  the  largest  wholesale  suppliers  of  gasoline  and 
distillates  to  resellers  in  the  United  States.  We  also  operate  Speedway,  the  second  largest  chain  of 
company-owned and operated retail gasoline and convenience stores in the United States, which we have 
agreed to sell to 7-Eleven, Inc. (“7-Eleven”) for $21 billion in cash, subject to certain adjustments based on 
the  levels  of  cash,  debt  and  working  capital  at  closing  and  certain  other  items.  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.  In  addition,  our  integrated  midstream  energy  asset 
network  links  producers  of  natural  gas  and  NGLs  from  some  of  the  largest  supply  basins  in  the  United 
States to domestic and international markets. 

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

•

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

• Midstream – transports, stores, distributes and markets crude oil and refined products principally 
for the Refining & Marketing segment via refining logistics assets, pipelines, terminals, towboats 
and  barges;  gathers,  processes  and  transports  natural  gas;  and  gathers,  transports,  fractionates, 
stores  and  markets  NGLs.  The  Midstream  segment  primarily  reflects  the  results  of  MPLX  LP 
(“MPLX”). MPLX is a diversified, large-cap master limited partnership (“MLP”) formed in 2012 
that  owns  and  operates  midstream  energy  infrastructure  and  logistics  assets  and  provides  fuels 
distribution  services.  As  of  December  31,  2020,  we  owned  the  general  partner  of  MPLX  and 
approximately 62 percent of the outstanding MPLX common units.

Corporate History and Structure

MPC was incorporated in Delaware on November 9, 2009 in connection with an internal restructuring of 
Marathon  Oil  Corporation  (“Marathon  Oil”).  On  May  25,  2011,  the  Marathon  Oil  board  of  directors 
approved  the  spinoff  of  its  Refining,  Marketing  &  Transportation  Business  into  an  independent,  publicly 
traded company, MPC, through the distribution of MPC common stock to the stockholders of Marathon Oil 
on June 30, 2011. Our common stock trades on the NYSE under the ticker symbol “MPC.” 

On  October  1,  2018,  we  acquired  Andeavor.  Andeavor  shareholders  received  in  the  aggregate 
approximately 239.8 million shares of MPC common stock valued at $19.8 billion and $3.5 billion in cash. 
Andeavor  was  a  highly  integrated  marketing,  logistics  and  refining  company  operating  primarily  in  the 
Western and Mid-Continent United States. Our acquisition of Andeavor in 2018 substantially increased our 
geographic diversification and the scale of our assets, which provides increased opportunities to optimize 
our system.

Recent Developments

Strategic Actions to Enhance Shareholder Value

Speedway Sale
On  August  2,  2020,  we  entered  into  a  definitive  agreement  to  sell  Speedway,  our  company-owned  and 
operated  retail  transportation  fuel  and  convenience  store  business,  to  7-Eleven  for  $21  billion  in  cash, 

4

subject to certain adjustments based on the levels of cash, debt and working capital at closing and certain 
other items. The taxable transaction is targeted to close by the end of the first quarter of 2021, subject to 
customary closing conditions and the receipt of regulatory approvals. This transaction is expected to result 
in after-tax cash proceeds of approximately $16.5 billion. We expect to use the proceeds from the sale to 
strengthen the balance sheet and return capital to shareholders. 

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

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

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

•

•

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

Beginning  August  2,  2020,  in  accordance  with  ASC  360,  Property,  Plant,  and  Equipment,  we 
ceased  recording  depreciation  and  amortization  for  Speedway’s  property,  plant  and  equipment, 
finite-lived intangible assets and right of use lease assets.

Midstream Review
On March 18, 2020, we announced that MPC’s board of directors unanimously decided to maintain MPC’s 
current midstream structure, with MPC remaining, through a wholly owned subsidiary, the general partner 
of MPLX. This decision concluded a comprehensive evaluation, led by a special committee of the board, 
that included extensive input from multiple external advisors and significant feedback from investors.

OUR OPERATIONS

Our operations consist of two reportable operating segments: Refining & Marketing and Midstream.

REFINING & MARKETING

Refineries

We currently own and operate refineries in the Gulf Coast, Mid-Continent and West Coast regions of the 
United  States  with  an  aggregate  crude  oil  refining  capacity  of  2,874  mbpcd.  During  2020,  our  refineries 
processed  2,418  mbpd  of  crude  oil  and  165  mbpd  of  other  charge  and  blendstocks.  During  2019,  our 
refineries processed 2,902 mbpd of crude oil and 210 mbpd of other charge and blendstocks. 

Our  refineries  include  crude  oil  atmospheric  and  vacuum  distillation,  fluid  catalytic  cracking, 
hydrocracking, catalytic reforming, coking, desulfurization and sulfur recovery units. The refineries process 
a wide variety of condensate and light and heavy crude oils purchased from various domestic and foreign 
suppliers. We produce numerous refined products, ranging from transportation fuels, such as reformulated 
gasolines, blend-grade gasolines intended for blending with ethanol and ULSD fuel, to heavy fuel oil and 
asphalt. Additionally, we manufacture aromatics, propane, propylene and sulfur. See the Refined Product 
Marketing section for further information about the products we produce. 

5

Our  refineries  are  integrated  with  each  other  via  pipelines,  terminals  and  barges  to  maximize  operating 
efficiency. The transportation links that connect our refineries allow the movement of intermediate products 
between  refineries  to  optimize  operations,  produce  higher  margin  products  and  efficiently  utilize  our 
processing  capacity.  Also,  shipping  intermediate  products  between  facilities  during  partial  refinery 
shutdowns allows us to utilize processing capacity that is not directly affected by the shutdown work.

Following is a description of each of our refineries and their capacity by region.

market. Our term contracts generally have market-related pricing provisions. The following table provides 
information on our sources of crude oil for each of the last three years. It includes crude sourced for the 
refineries  acquired  in  the  Andeavor  acquisition  from  October  1,  2018  forward.  The  crude  oil  sourced 
outside of North America was acquired from various foreign national oil companies, production companies 
and trading companies.

Our refineries receive crude oil and other feedstocks and distribute our refined products through a variety of 
channels, including pipelines, trucks, railcars, ships and barges. 

Renewable Fuels 

During 2020, we completed the conversion of our Dickinson, North Dakota refinery into an approximately 
184 million gallons per year renewable diesel facility.

We also progressed activities associated with the conversion of the Martinez refinery to a renewable diesel 
facility,  including  applying  for  permits,  advancing  discussions  with  feedstock  suppliers,  and  beginning 
detailed  engineering  activities.  As  envisioned,  the  Martinez  facility  would  start  producing  approximately 
260 million gallons per year of renewable diesel by the second half of 2022, with a potential to build to full 
capacity of approximately 730 million gallons per year by the end of 2023. On February 24, 2021, MPC’s 
board of directors approved these plans.

We  own  a  biofuel  production  facility  in  Cincinnati,  Ohio  that  produces  biodiesel,  glycerin  and  other  by-
products. The capacity of the plant is approximately 91 million gallons per year. 

Our  wholly  owned  subsidiary,  Virent,  is  an  advanced  biofuels  facility  in  Madison,  Wisconsin  that  is 
working to commercialize a process for converting biobased feedstocks into renewable fuels and chemicals.

We hold an ownership interest in ethanol production facilities in Albion, Michigan; Logansport, Indiana; 
Greenville,  Ohio  and  Denison,  Iowa.  These  plants  have  a  combined  ethanol  production  capacity  of 
approximately 475 million gallons per year and are managed by our joint venture partner, The Andersons.

Refined Product Marketing

Our refined products are sold to independent retailers, wholesale customers, our brand jobbers and direct 
dealers.  In  addition,  we  sell  refined  products  for  export  to  international  customers.  As  of  December  31, 
2020,  there  were  7,090  branded  outlets  in  35  states,  the  District  of  Columbia  and  Mexico  where 
independent  entrepreneurs  primarily  maintain  Marathon-branded  outlets.  We  also  have  long-term  supply 
contracts  for  1,093  direct  dealer  locations  primarily  in  Southern  California,  largely  under  the  ARCO® 
brand. We believe we are one of the largest wholesale suppliers of gasoline and distillates to resellers and 
consumers within our 41-state market area.

Gasoline and Distillates 

We sell gasoline, gasoline blendstocks and distillates (including No. 1 and No. 2 fuel oils, jet fuel, kerosene 
and diesel fuel) to wholesale customers, Marathon-branded jobbers, direct dealers and in the spot market. In 
addition,  we  sell  diesel  fuel  and  gasoline  for  export  to  international  customers.  The  demand  for  gasoline 
and  distillates  is  seasonal  in  many  of  our  markets,  with  demand  typically  at  its  highest  levels  during  the 
summer months.

Feedstocks and Petrochemicals

We are a producer and marketer of feedstocks and petrochemicals. Product availability varies by refinery 
and  includes,  among  others,  propylene,  naphtha,  butane,  xylene,  benzene,  alkylate,  cumene,  raffinate, 
toluene and platformate. We market these products domestically to customers in the chemical, agricultural 
and fuel-blending industries. In addition, we produce fuel-grade coke at our Garyville, Detroit, Galveston 
Bay  and  Los  Angeles  refineries,  which  is  used  for  power  generation  and  in  miscellaneous  industrial 
applications,  and  anode-grade  coke  at  our  Los  Angeles  and  Robinson  refineries,  in  addition  to  calcined 
coke at our Los Angeles refinery, which are both used to make carbon anodes for the aluminum smelting 
industry.

Asphalt

We have refinery-based asphalt production capacity of up to 139 mbpcd, which includes asphalt cements, 
polymer-modified  asphalt,  emulsified  asphalt,  industrial  asphalts  and  roofing  flux.  We  have  a  broad 
customer base, including asphalt-paving contractors, resellers, government entities (states, counties, cities 
and  townships)  and  asphalt  roofing  shingle  manufacturers.  We  sell  asphalt  in  the  domestic  and  export 
wholesale markets via rail, barge and vessel.

Propane

We produce propane at all of our refineries. Propane is primarily used for home heating and cooking, as a 
feedstock  within  the  petrochemical  industry,  for  grain  drying  and  as  a  fuel  for  trucks  and  other  vehicles. 
Our propane sales are split approximately 80 percent and 20 percent between the home heating market and 
petrochemical consumers, respectively.

Heavy Fuel Oil

We  produce  and  market  heavy  residual  fuel  oil  or  related  components,  including  slurry,  at  all  of  our 
refineries.  Heavy  residual  fuel  oil  is  primarily  used  in  the  utility  and  ship  bunkering  (fuel)  industries, 
though there are other more specialized uses of the product.

Terminals and Transportation

We  transport,  store  and  distribute  crude  oil,  feedstocks  and  refined  products  through  pipelines,  terminals 
and marine fleets owned by MPLX and third parties in our market areas. 

We  own  a  fleet  of  transport  trucks  and  trailers  for  the  movement  of  refined  products  and  crude  oil.  In 
addition,  we  maintain  a  fleet  of  leased  and  owned  railcars  for  the  movement  and  storage  of  refined 
products.

The locations and detailed information about our Refining & Marketing assets are included under Item 2. 
Properties and are incorporated herein by reference. 

Competition, Market Conditions and Seasonality

The downstream petroleum business is highly competitive, particularly with regard to accessing crude oil 
and  other  feedstock  supply  and  the  marketing  of  refined  products.  We  compete  with  a  number  of  other 
companies to acquire crude oil for refinery processing and in the distribution and marketing of a full array 
of refined products. Based upon company data as reported in the “The Oil & Gas Journal 2020 Worldwide 
Refinery Survey,” we ranked first among U.S. petroleum companies on the basis of U.S. crude oil refining 
capacity.

We compete in four distinct markets for the sale of refined products—wholesale, including exports, spot, 
branded  and  retail  distribution.  Our  marketing  operations  compete  with  numerous  other  independent 
marketers, integrated oil companies and high-volume retailers. We compete with companies in the sale of 
refined  products  to  wholesale  marketing  customers,  including  private-brand  marketers  and  large 
commercial  and  industrial  consumers;  companies  in  the  sale  of  refined  products  in  the  spot  market;  and 
refiners  or  marketers  in  the  supply  of  refined  products  to  refiner-branded  independent  entrepreneurs.  In 
addition,  we  compete  with  producers  and  marketers  in  other  industries  that  supply  alternative  forms  of 
energy and fuels to satisfy the requirements of our industrial, commercial and retail consumers.

Market  conditions  in  the  oil  and  gas  industry  are  cyclical  and  subject  to  global  economic  and  political 
events and new and changing governmental regulations. Our operating results are affected by price changes 
in crude oil, natural gas and refined products, as well as changes in competitive conditions in the markets 
we serve. Price differentials between sweet and sour crude oils, ANS, WTI and LLS crude oils and other 
market structure impacts also affect our operating results. 

Demand for gasoline, diesel fuel and asphalt is higher during the spring and summer months than during 
the  winter  months  in  most  of  our  markets,  primarily  due  to  seasonal  increases  in  highway  traffic  and 
construction.  As  a  result,  the  operating  results  for  our  Refining  &  Marketing  segment  for  the  first  and 
fourth quarters may be lower than for those in the second and third quarters of each calendar year.

MIDSTREAM 

The  Midstream  segment  primarily  includes  the  operations  of  MPLX,  our  sponsored  MLP,  and  certain 
related operations retained by MPC.

MPLX

MPLX owns and operates a network of crude oil, natural gas and refined product pipelines and has joint 
ownership interests in other crude oil and refined products pipelines. MPLX also owns and operates light 
products terminals, storage assets and maintains a fleet of owned and leased towboats and barges. MPLX’s 
assets  also  include  natural  gas  gathering  systems  and  natural  gas  processing  and  NGL  fractionation 
complexes. 

10

MPC-Retained Midstream Assets and Investments 

We  have  ownership  interests  in  several  crude  oil  and  refined  products  pipeline  systems  and  pipeline 
companies and have indirect ownership interests in two ocean vessel joint ventures through our investment 
in Crowley Coastal Partners. 

The  locations  and  detailed  information  about  our  Midstream  assets  are  included  under  Item  2.  Properties 
and are incorporated herein by reference. 

Competition, Market Conditions and Seasonality

Our  Midstream  operations  face  competition  for  natural  gas  gathering,  crude  oil  transportation  and  in 
obtaining natural gas supplies for our processing and related services; in obtaining unprocessed NGLs for 
gathering,  transportation  and  fractionation;  and  in  marketing  our  products  and  services.  Competition  for 
natural gas supplies is based primarily on the location of gas gathering facilities and gas processing plants, 
operating  efficiency  and  reliability,  residue  gas  and  NGL  market  connectivity,  the  ability  to  obtain  a 
satisfactory  price  for  products  recovered  and  the  fees  charged  for  the  services  supplied  to  the  customer. 
Competition  for  oil  supplies  is  based  primarily  on  the  price  and  scope  of  services,  location  of  gathering/
transportation  and  storage  facilities  and  connectivity  to  the  best  priced  markets.  Competitive  factors 
affecting  our  fractionation  services  include  availability  of  fractionation  capacity,  proximity  to  supply  and 
industry  marketing  centers,  the  fees  charged  for  fractionation  services  and  operating  efficiency  and 
reliability of service. Competition for customers to purchase our natural gas and NGLs is based primarily 
on price, credit and market connectivity. In addition, certain of our Midstream operations are subject to rate 
regulation, which affects the rates that our common carrier pipelines can charge for transportation services 
and the return we obtain from such pipelines.

Our Midstream segment can be affected by seasonal fluctuations in the demand for natural gas and NGLs 
and the related fluctuations in commodity prices caused by various factors such as changes in transportation 
and travel patterns and variations in weather patterns from year to year. 

REGULATORY MATTERS

Our operations are subject to numerous laws and regulations, including those relating to the protection of 
the environment. Such laws and regulations include, among others, the Clean Air Act (“CAA”) with respect 
to  air  emissions,  the  Clean  Water  Act  (“CWA”)  with  respect  to  water  discharges,  the  Resource 
Conservation  and  Recovery  Act  (“RCRA”)  with  respect  to  solid  and  hazardous  waste  treatment,  storage 
and disposal, the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) 
with  respect  to  releases  and  remediation  of  hazardous  substances  and  the  Oil  Pollution  Act  of  1990 
(“OPA-90”)  with  respect  to  oil  pollution  and  response.  In  addition,  many  states  where  we  operate  have 
similar laws. New laws are being enacted and regulations are being adopted on a continuing basis, and the 
costs of compliance with such new laws and regulations are very difficult to estimate until finalized.

For a discussion of environmental capital expenditures and costs of compliance, see Item 7. Management’s 
Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations-Environmental  Matters  and 
Compliance Costs. For additional information regarding regulatory risks, see Item 1A. Risk Factors.

Air

Greenhouse Gas Emissions

We  believe  it  is  likely  that  the  scientific  and  political  attention  to  greenhouse  gas  emissions,  climate 
change, and climate adaptation will continue, with the potential for further regulations that could affect our 
operations.  Currently,  legislative  and  regulatory  measures  to  address  greenhouse  gas  emissions  are  in 
various  phases  of  review,  discussion  or  implementation.  Reductions  in  greenhouse  gas  emissions  could 
result in increased costs to (i) operate and maintain our facilities, (ii) install new emission controls at our 
facilities, (iii) capture the emissions from our facilities and (iv) administer and manage any greenhouse gas 
emissions programs, including acquiring emission credits or allotments.

In  January  2021,  President  Biden  announced  that  the  United  States  was  rejoining  the  2015  Paris  UN 
Climate  Change  Conference  Agreement,  effective  February  19,  2021.  President  Biden  also  issued  an 
Executive Order on climate change in which he announced putting the U.S. on a path to achieve net-zero 
carbon emissions, economy-wide, by 2050. The Executive Order also calls for the federal government to 
pause oil and gas leasing on federal lands, reduce methane emissions from the oil and gas sector as quickly 
as possible, and requires federal permitting decisions to consider the effects of greenhouse gas emissions 

11

and  climate  change.  In  a  second  Executive  Order,  President  Biden  reestablished  a  working  group  to 
develop the social cost of carbon and the social cost of methane. The social cost of carbon and social cost of 
methane can be used to weigh the costs and benefits of proposed regulations. A higher social cost of carbon 
could support more stringent greenhouse gas emission regulation.

States  are  becoming  active  in  regulating  greenhouse  gas  emissions.  These  measures  may  include  state 
actions to develop statewide or regional programs to impose emission reductions. These measures may also 
include low-carbon fuel standards, such as the California program, or a state carbon tax. These measures 
could  result  in  increased  costs  to  operate  and  maintain  our  facilities,  capital  expenditures  to  install  new 
emission controls and costs to administer any carbon trading or tax programs implemented. For example, 
the California state legislature enacted AB 398, which provides direction and parameters on utilizing cap 
and trade after 2020 to meet the 40 percent reduction target from 1990 levels by 2030 specified in SB 32. 
Compliance with the cap and trade program is demonstrated through a market-based credit system. Much 
of  the  compliance  costs  associated  with  these  California  regulations  are  ultimately  passed  on  to  the 
consumer in the form of higher fuel costs. States are increasingly announcing aspirational goals to be net-
zero carbon emissions by a certain date through both legislation and executive orders. To date, these states 
have not provided significant details as to achievement of these goals; however, meeting these aspirations 
will require a reduction in fossil fuel combustion and/or a mechanism to capture greenhouse gases from the 
atmosphere.  As  a  result,  we  cannot  currently  predict  the  impact  of  these  potential  regulations  on  our 
liquidity, financial position, or results of operations.

Other Air Emissions

In  2015,  United  States  Environmental  Protection  Agency  (“EPA”)  finalized  a  revision  to  the  National 
Ambient Air Quality Standards (“NAAQS”) for ozone. The EPA lowered the primary ozone NAAQS from 
75 ppb to 70 ppb. In December 2020, the EPA published a rule maintaining this standard. Designation as a 
nonattainment  area  could  result  in  increased  costs  associated  with,  or  result  in  cancellation  or  delay  of, 
capital projects at our facilities, or could require nitrogen oxide (“NOx”) and/or volatile organic compound 
(“VOC”) reductions that could result in increased costs to our facilities.

In  California,  the  Board  for  the  South  Coast  Air  Quality  Management  District  (“SCAQMD”)  passed 
amendments  to  the  Regional  Clean  Air  Incentives  Market  (“RECLAIM”)  that  became  effective  in  2016, 
requiring  a  staged  reduction  of  nitrogen  oxide  emissions  through  2022.  In  2017,  the  State  of  California 
passed AB 617, which requires implementation of best available retrofit control technology (“BARCT”) on 
specific  facilities,  including  facilities  subject  to  RECLAIM.  In  response  to  AB  617,  the  SCAQMD  is 
currently working to identify BARCT and determine whether to “sunset” the existing RECLAIM program. 
A “sunset” of the RECLAIM program and application of BARCT is expected to result in increased costs to 
operate and maintain our Los Angeles refinery.

Water

We maintain numerous discharge permits as required under the National Pollutant Discharge Elimination 
System program of the CWA and have implemented systems to oversee our compliance with these permits. 
In addition, we are regulated under OPA-90, which, among other things, requires the owner or operator of a 
tank  vessel  or  a  facility  to  maintain  an  emergency  plan  to  respond  to  releases  of  oil  or  hazardous 
substances. OPA-90 also requires the responsible company to pay resulting removal costs and damages and 
provides for civil penalties and criminal sanctions for violations of its provisions. We operate tank vessels 
and  facilities  from  which  spills  of  oil  and  hazardous  substances  could  occur.  We  have  implemented 
emergency  oil  response  plans  for  all  of  our  components  and  facilities  covered  by  OPA-90  and  we  have 
established  Spill  Prevention,  Control  and  Countermeasures  plans  for  all  facilities  subject  to  such 
requirements. Some coastal states in which we operate have passed state laws similar to OPA-90, but with 
expanded liability provisions, that include provisions for cargo owner responsibility as well as ship owner 
and operator responsibility.

On October 22, 2019, the EPA and the United States Army Corps of Engineers (“Army Corps”) published 
a final rule to repeal the 2015 “Clean Water Rule: Definition of Waters of the United States” (“2015 Rule”), 
which  amended  portions  of  the  Code  of  Federal  Regulations  (“CFR”)  to  restore  the  regulatory  text  that 
existed prior to the 2015 Rule, effective December 23, 2019. The rule repealing the 2015 Clean Water Rule 
has  been  challenged  in  multiple  federal  courts.  On  April  21,  2020,  the  EPA  and  the  Army  Corps 
promulgated the Navigable Waters Protection Rule (“2020 Rule”) to define “waters of the United States.” 
The 2020 Rule has been challenged in court. The Biden administration has signaled its intent to revisit the 
definition of “waters of the United States,” and replace it with a definition consistent with the 2015 Rule. A 

12

broader definition could result in increased cost of compliance or increased capital costs for construction of 
new facilities or expansion of existing facilities. 

In  April  2020,  the  U.S.  District  Court  in  Montana  vacated  Nationwide  Permit  12  (“NWP  12”),  which 
authorizes the placement of fill material in “waters of the United States” for utility line activities as long as 
certain  best  management  practices  are  implemented.  The  decision  was  ultimately  appealed  to  the  United 
States Supreme Court, which partially reversed the district court’s decision, temporarily reinstating NWP 
12  for  all  projects  except  the  Keystone  XL  oil  pipeline.  The  United  States  Army  Corps  of  Engineers 
subsequently reissued its nationwide permit authorizations on January 13, 2021, by dividing the NWP that 
authorizes  utility  line  activities  (NWP  12)  into  three  separate  NWPs  that  address  the  differences  in  how 
different  utility  line  projects  are  constructed,  the  substances  they  convey,  and  the  different  standards  and 
best management practices that help ensure those NWPs authorize only those activities that have no more 
than  minimal  adverse  environmental  effects.  The  2021  authorization  may  be  challenged  in  court  or  the 
Biden Administration may repeal or replace the 2021 authorization in a subsequent rulemaking. Repeal or 
replacement of the rule could impact pipeline maintenance activities. 

As  part  of  our  emergency  response  activities,  we  have  used  aqueous  film  forming  foam  (“AFFF”) 
containing  per-  and  polyfluoroalkyl  substances  (“PFAS”)  chemicals  as  a  fire  suppressant.  At  this  time, 
AFFFs  containing  PFAS  are  the  only  proven  foams  that  can  prevent  and  control  most  flammable 
petroleum-based liquid fires. 

In May 2016, the EPA issued lifetime health advisories (“HAs”) and health effects support documents for 
two PFAS substances - Perfluorooctanoic Acid (“PFOA”) and Perfluorooctane Sulfonate (“PFOS”). Then, 
in February 2019, EPA issued a PFAS Action Plan identifying actions the EPA is planning to take to study 
and regulate various PFAS chemicals. The EPA identified that it would evaluate, among other actions, (1) 
proposing  national  drinking  water  standards  for  PFOA  and  PFOS,  (2)  develop  cleanup  recommendations 
for PFOA and PFOS, (3) evaluate listing PFOA and PFOS as hazardous substances under CERCLA, and 
(4)  conduct  toxicity  assessments  for  other  PFAS  chemicals.  To  date  EPA  has  not  issued  any  further 
regulations for PFAS under the Trump administration; however, the Biden Administration has indicated its 
intent to issue proposed rules to regulate PFAS, which could include the designation of variants of PFAS as 
CERCLA hazardous substances and/or establish national drinking water standards. Congress may also take 
further action to regulate PFAS. We cannot currently predict the impact of potential statutes or regulations 
on our operations or remediation costs.

In addition, many states are actively proposing and adopting legislation and regulations relating to the use 
of AFFF. Additionally, some states are adopting and proposing state-specific drinking water and cleanup 
standards for various PFAS. We cannot currently predict the impact of these regulations on our liquidity, 
financial position, or results of operations.

Solid Waste

We  continue  to  seek  methods  to  minimize  the  generation  of  hazardous  wastes  in  our  operations.  RCRA 
establishes standards for the management of solid and hazardous wastes. Besides affecting waste disposal 
practices,  RCRA  also  addresses  the  environmental  effects  of  certain  past  waste  disposal  operations,  the 
recycling of wastes and the regulation of USTs containing regulated substances.

Remediation

We  own  or  operate,  or  have  owned  or  operated,  certain  convenience  stores  and  other  locations  where, 
during the normal course of operations, releases of refined products from USTs have occurred. Federal and 
state laws require that contamination caused by such releases at these sites be assessed and remediated to 
meet  applicable  standards.  Penalties  or  other  sanctions  may  be  imposed  for  noncompliance.  The 
enforcement of the UST regulations under RCRA has been delegated to the states, which administer their 
own UST programs. Our obligation to remediate such contamination varies, depending on the extent of the 
releases  and  the  applicable  state  laws  and  regulations.  A  portion  of  these  remediation  costs  may  be 
recoverable from the appropriate state UST reimbursement funds once the applicable deductibles have been 
satisfied.  We  also  have  ongoing  remediation  projects  at  a  number  of  our  current  and  former  refinery, 
terminal and pipeline locations.

Claims under CERCLA and similar state acts have been raised with respect to the clean-up of various waste 
disposal  and  other  sites.  CERCLA  is  intended  to  facilitate  the  clean-up  of  hazardous  substances  without 
regard to fault. Potentially responsible parties for each site include present and former owners and operators 
of, transporters to and generators of the hazardous substances at the site. Liability is strict and can be joint 

13

and several. Because of various factors including the difficulty of identifying the responsible parties for any 
particular  site,  the  complexity  of  determining  the  relative  liability  among  them,  the  uncertainty  as  to  the 
most desirable remediation techniques and the amount of damages and clean-up costs and the time period 
during  which  such  costs  may  be  incurred,  we  are  unable  to  reasonably  estimate  our  ultimate  cost  of 
compliance  with  CERCLA;  however,  we  do  not  believe  such  costs  will  be  material  to  our  business, 
financial condition, results of operations or cash flows.

Renewable Fuels and Other Fuels Requirements

The  U.S.  Congress  passed  the  Energy  Independence  and  Security  Act  of  2007  (“EISA”),  which,  among 
other things, set a target of 35 miles per gallon for the combined fleet of cars and light trucks in the United 
States  by  model  year  2020.  In  March  2020,  the  EPA  and  the  National  Highway  Traffic  Safety 
Administration  (“NHTSA”)  released  the  final  Safer  Affordable  Fuel-Efficient  (“SAFE”)  Vehicles  Rule 
setting corporate average fuel economy (“CAFE”) and carbon dioxide (“CO2”) standards for model years 
2021-2026  passenger  cars  and  light  trucks.  The  final  rule  increases  the  stringency  of  CAFE  and  CO2 
emission  standards  by  1.5  percent  each  year  from  model  years  2021  through  2026.  The  rule  has  been 
challenged  in  court  and  could  be  revised  by  the  Biden  Administration  through  notice  and  comment 
rulemaking. Higher CAFE standards for cars and light trucks have the potential to reduce demand for our 
transportation fuels. 

In addition, the NHTSA and the EPA issued rules providing that the Energy Policy and Conservation Act 
(“EPCA”) preempts state regulations of tailpipe carbon dioxide emissions, withdrew the waiver granted to 
California for its Advanced Clean Car program and determined that the Clean Air Act permits other states 
to  adopt  only  those  California  standards  that  are  designed  to  control  traditional  “criteria  pollutants.” 
California  may  establish  per  its  Clean  Air  Act  waiver  authority  different  standards  that  could  apply  in 
multiple  states.  California’s  governor  issued  an  executive  order  requiring  sales  of  all  new  passenger 
vehicles  in  the  state  be  zero-emission  by  2035.  Other  states  have  issued,  or  may  issue,  zero  emission 
vehicle  mandates.  The  Biden  Administration  could  reinstate  the  California  waiver  and  may  take  federal 
action to incentivize or mandate zero emission vehicle production.

Pursuant  to  the  Energy  Policy  Act  of  2005  and  the  EISA,  the  EPA  has  promulgated  a  Renewable  Fuel 
Standard (“RFS”) program that requires certain volumes of renewable fuel be blended with our products. 
By November 30 of each year, the EPA is required to promulgate the annual renewable fuel standards for 
the following compliance year. In a legal challenge to the 2014-2016 volumes, the D.C. Circuit Court of 
Appeals  vacated  the  total  renewable  volume  for  2016  and  remanded  to  the  EPA  for  reconsideration 
consistent  with  the  court’s  opinion.  A  rule  that  increases  the  total  renewable  volume  for  any  compliance 
year to make up for the 2016 shortfall could increase our cost of compliance with the RFS program, require 
us to use carryover RINs and be detrimental to the RIN market. 

The EPA has finalized the annual renewable fuel standards for the year 2020. For the first time, the EPA 
has proposed to reallocate to non-exempt obligated parties the renewable volume obligations of the refiners 
that were granted a small refinery exemption. Also, the Tenth Circuit Court of Appeals held that a small 
refinery  is  eligible  for  an  exemption  from  the  RFS  only  if  it  is  applying  for  an  extension  of  its  original 
exemption.  According  to  the  EPA’s  data,  seven  refineries  were  granted  the  small  refinery  exemption  in 
2015. The United States Supreme Court has granted certiorari in the 10th Circuit case. If the 10th Circuit 
decision  is  upheld,  EPA’s  reallocation  of  volumes  could  be  greater  than  the  actual  volumes  exempted  in 
2020. The reallocation of volumes under the 2020 rule or the invalidation of past small refinery exemptions 
granted to us or other refiners could result in a decrease in the RIN bank, an increase in the price of RINs or 
an increase in the amount of renewable fuel we are required to blend, any of which could increase MPC’s 
RFS  cost  of  compliance.  Further,  the  EPA  has  failed  to  promulgate  timely  the  annual  renewable  fuel 
standards for 2021.

The  RFS  is  satisfied  primarily  with  ethanol  blended  into  gasoline.  Vehicle,  regulatory  and  infrastructure 
constraints  limit  the  blending  of  significantly  more  than  10  percent  ethanol  into  gasoline  (“E10”).  Since 
2016,  the  volume  requirements  have  resulted  in  the  ethanol  content  of  gasoline  exceeding  the  E10 
blendwall, which will require obligated parties to either sell E15 or ethanol flex fuel at levels that exceed 
historical levels or retire carryover RINs.

There is currently no regulatory method for verifying the validity of the RINs sold on the open market. We 
have developed a RIN integrity program to vet the RINs that we purchase, and we incur costs to audit RIN 
generators.  Nevertheless,  if  any  of  the  RINs  that  we  purchase  and  use  for  compliance  are  found  to  be 
invalid, we could incur costs and penalties for replacing the invalid RINs.

In addition to the federal Renewable Fuel Standards, certain states have, or are considering, promulgation 
of  state  renewable  or  low  carbon  fuel  standards.  For  example,  California  began  implementing  its  Low 
Carbon Fuel Standard (“LCFS”) in January 2011. In September 2015, the CARB approved the re-adoption 
of the LCFS, which became effective on January 1, 2016, to address procedural deficiencies in the way the 
original regulation was adopted. The LCFS was amended again in 2018 with the current version targeting a 
20 percent reduction in fuel carbon intensity from a 2010 baseline by 2030. We incur costs to comply with 
the California LCFS, and these costs may increase if the cost of LCFS credits increases.

In sum, the RFS has required, and may in the future continue to require, additional capital expenditures or 
expenses by us to accommodate increased renewable fuels use. We may experience a decrease in demand 
for refined products due to an increase in combined fleet mileage or due to refined products being replaced 
by  renewable  fuels.  Demand  for  our  refined  products  also  may  decrease  as  a  result  of  low  carbon  fuel 
standard programs or electric vehicle mandates.

Safety Matters

We  are  subject  to  oversight  pursuant  to  the  federal  Occupational  Safety  and  Health  Act,  as  amended 
(“OSHA”),  as  well  as  comparable  state  statutes  that  regulate  the  protection  of  the  health  and  safety  of 
workers.  We  believe  that  we  have  conducted  our  operations  in  substantial  compliance  with  OSHA 
requirements,  including  general  industry  standards,  record-keeping  requirements  and  monitoring  of 
occupational exposure to regulated substances.

We are also subject at regulated facilities to the OSHA’s Process Safety Management (“PSM”) and EPA’s 
Risk Management Program requirements, which are intended to prevent or minimize the consequences of 
catastrophic  releases  of  toxic,  reactive,  flammable  or  explosive  chemicals.  The  application  of  these 
regulations can result in increased compliance expenditures.

In  general,  we  expect  industry  and  regulatory  safety  standards  to  become  stricter  over  time,  resulting  in 
increased compliance expenditures. While these expenditures cannot be accurately estimated at this time, 
we do not expect such expenditures will have a material adverse effect on our results of operations.

The DOT has adopted safety regulations with respect to the design, construction, operation, maintenance, 
inspection  and  management  of  our  pipeline  assets.  These  regulations  contain  requirements  for  the 
development and implementation of pipeline integrity management programs, which include the inspection 
and  testing  of  pipelines  and  the  correction  of  anomalies.  These  regulations  also  require  that  pipeline 
operation  and  maintenance  personnel  meet  certain  qualifications  and  that  pipeline  operators  develop 
comprehensive spill response plans. 

Tribal Lands

Various federal agencies, including the EPA and the Department of the Interior, along with certain Native 
American  tribes,  promulgate  and  enforce  regulations  pertaining  to  oil  and  gas  operations  on  Native 
American tribal lands where we operate. These regulations include such matters as lease provisions, drilling 
and  production  requirements,  and  standards  to  protect  environmental  quality  and  cultural  resources.  In 
addition,  each  Native  American  tribe  is  a  sovereign  nation  having  the  right  to  enforce  certain  laws  and 
regulations and to grant approvals independent from federal, state and local statutes and regulations. These 
laws and regulations may increase our costs of doing business on Native American tribal lands and impact 
the viability of, or prevent or delay our ability to conduct, our operations on such lands.

TRADEMARKS, PATENTS AND LICENSES 

Our Marathon and ARCO trademarks are material to the conduct of our refining and marketing operations, 
and our Speedway trademark is material to the conduct of our retail operations. We currently hold a number 
of  U.S.  and  foreign  patents  and  have  various  pending  patent  applications.  Although  in  the  aggregate  our 
patents and licenses are important to us, we do not regard any single patent or license or group of related 
patents  or  licenses  as  critical  or  essential  to  our  business  as  a  whole.  In  general,  we  depend  on  our 
technological capabilities and the application of know-how rather than patents and licenses in the conduct 
of our operations.

HUMAN CAPITAL

We  believe  our  employees  are  our  greatest  source  of  strength,  and  our  culture  reflects  the  quality  of 
individuals  across  our  workforce.  Our  collaborative  efforts  to  foster  an  inclusive  environment,  provide 

15

broad-based development and mentorship opportunities, recognize and reward accomplishments, and offer 
benefits that support the well-being of our employees and their families contribute to increased engagement 
and fulfilling careers. Empowering our people and prioritizing accountability also are key components for 
developing MPC’s high-performing culture, which is critical to achieving our strategic vision. 

Employee Profile

As  of  December  31,  2020,  we  employed  approximately  57,900  people  in  full-time  and  part-time  roles. 
Excluding  employees  of  Speedway,  which  is  targeted  to  be  sold  in  the  first  quarter  of  2021,  we  employ 
approximately 18,600 people in full-time and part-time roles. Many of these employees provide services to 
MPLX,  for  which  we  are  reimbursed  in  accordance  with  employee  service  agreements.  Approximately 
3,770 of the 18,600 employees are covered by collective bargaining agreements.

Talent Management

Executing  our  strategic  vision  requires  that  we  attract  and  retain  the  best  talent.  Recruiting  and  retention 
success  requires  that  we  effectively  nurture  new  employees,  providing  opportunities  for  long-term 
engagement and career advancement. We also appropriately reward high-performers and offer competitive 
benefits.  Our  Talent  Acquisition  team  consists  of  three  segments:  Executive  Recruiting,  Experienced 
Recruiting  and  University  Recruiting.  The  specialization  within  each  group  allows  us  to  specifically 
address  MPC’s  broad  range  of  current  and  future  talent  needs,  as  well  as  devote  time  and  attention  to 
candidates during the hiring process. We value diverse perspectives in the workforce, and accordingly we 
seek candidates with a variety of backgrounds and experience. Our primary source of full-time, entry-level 
new  hires  is  our  intern/co-op  program.  Through  our  university  recruiters,  we  offer  college  students  who 
have  completed  their  freshman  year  the  opportunity  to  participate  in  our  hands-on  programs  focused  in 
areas of finance and accounting, marketing, engineering and IT.

We provide a broad range of leadership training opportunities to support the development of leaders at all 
levels.  Our  programs,  which  are  offered  across  the  organization  are  a  blended  approach  of  business  and 
leadership  content,  with  many  featuring  external  faculty.  We  utilize  various  learning  modalities,  such  as 
visual,  audio,  print,  tactile,  interactive,  kinesthetic,  experiential  and  leader-teaching-leader  to  address  and 
engage  different  learning  styles.  We  believe  networking  and  access  to  our  executive  team  are  a  key 
leadership success factor, and we incorporate these opportunities into all of our programs.

Compensation and Benefits

To ensure we are offering competitive pay packages in our recruitment and retention efforts, we annually 
benchmark  compensation,  including  base  salaries,  bonus  levels  and  equity  targets.  Our  annual  bonus 
program  is  a  critical  component  of  our  compensation,  as  it  provides  individual  reward  for  MPC’s 
achievement against preset financial and sustainability goals, encouraging a sense of employee ownership. 
Employees in our officer-level pay grades, as well as senior leaders and most mid-level leaders, are eligible 
to receive long-term equity incentive awards as part of their compensation.

We offer comprehensive benefits, including medical, dental and vision insurance for our employees, their 
spouses  or  domestic  partners,  and  their  dependents.  We  also  provide  retirement  programs,  life  insurance, 
education assistance, family assistance, short-term disability and paid vacation and sick time. Following our 
acquisition of Andeavor, we enhanced several of our benefits programs to reflect our larger, coast-to-coast 
organization.  We  increased  the  maximum  accrual  cap  for  vacation  banks  and  doubled  the  number  of 
college and trade school scholarships offered to the high school senior children of our employees through 
the  Marathon  Petroleum  Scholars  Program.  In  addition,  we  increased  our  paid  parental  leave  benefit  to 
eight weeks for birth mothers and four weeks for nonbirth parents, including adoptive and foster parents. 
Both  full-time  and  part-time  employees  are  eligible  for  this  benefit.  Parents  who  both  work  for  the 
company are each eligible for a parental pay benefit.

Inclusion

Our company-wide Diversity and Inclusion (“D&I”) program is managed by a dedicated D&I Office team 
and supported by leadership. Our program is based on our three-pillar D&I strategy, of building awareness, 
increasing  representation  and  ensuring  success.  The  strategy  focuses  on  understanding  the  benefits  of 
diverse perspectives, increasing diversity across the organization and recognizing that cultural inclusion is 
an  ongoing  process.  We  have  employee  networks  focusing  on  six  populations:  Asian,  Black,  Hispanic, 
Veterans,  Women  and  LGBTQ+.  Our  employee  networks  have  approximately  60  chapters  across  the 
company  and  all  networks  encourage  ally  membership.  This  broad  support  extends  also  to  our  leaders 
throughout MPC, with each employee network represented by two active executive sponsors. The sponsors 

16

form several counsels that meet regularly to share updates, gain alignment, build deeper connections across 
networks  and  pursue  collaboration  ideas.  Our  employee  networks  not  only  provide  opportunities  for  our 
employees  to  make  meaningful  and  supportive  connections,  but  they  also  serve  a  significant  role  in  our 
D&I strategy.

Safety 

We  are  committed  to  safe  operations  to  protect  the  health  and  safety  of  our  employees,  contractors  and 
communities.  Our  commitment  to  safe  operations  is  reflected  in  our  safety  systems  design,  our  well-
maintained equipment and by learning from our incidents. Part of our effort to promote safety includes a 
management system based on the principles of RC14001®, the Plan-Do-Check-Act continual improvement 
cycle,  and  our  Operational  Excellence  Management  System.  Together,  these  components  of  our  safety 
management system provide us with a comprehensive approach to managing risks and preventing incidents, 
illnesses  and  fatalities.  Additionally,  our  annual  cash  bonus  program  metrics  includes  several  employee, 
process and environmental safety metrics.

The  COVID-19  pandemic  has  underscored  for  us  the  importance  of  keeping  our  employees  safe  and 
healthy.  In  March  2020,  MPC  activated  its  Corporate  Emergency  Response  Team  to  ensure  a  consistent 
and  aggressive  response  across  all  facets  of  our  company.  The  safety  and  health  of  our  employees, 
including our essential personnel, were our top priorities. As part of our existing pandemic plan, we had a 
central  inventory  of  N95  respirators,  surgical  masks,  and  nitrile  gloves  to  supply  to  our  employees  and 
contractors  when  the  pandemic  began.  We  implemented  a  number  of  protective  measures  to  ensure 
employee  and  contractor  safety  as  they  continued  to  keep  our  critical  operations  running  safely.  We 
continue to monitor the situation and adapt our practices as appropriate.

ITEM 1A. RISK FACTORS 

You  should  carefully  consider  each  of  the  following  risks  and  all  the  other  information  contained  in  this 
Annual Report on Form 10-K in evaluating us and our common stock. Although the risks are organized by 
headings, and each risk is discussed separately, many are interrelated. Our business, financial condition, 
results  of  operations  and  cash  flows  could  be  materially  and  adversely  affected  by  these  risks,  and,  as  a 
result, the trading price of our common stock could decline.

Business and Operational Risks

The  COVID-19  pandemic  resulted  in  a  significant  decrease  in  demand  for  the  petroleum  products 
that we manufacture, sell, transport and store, which has had, and may continue to have, a material 
and adverse effect on our business and on general economic, financial and business conditions.

The  COVID-19  pandemic  continues  to  negatively  impact  worldwide  economic  and  commercial  activity. 
Travel  restrictions,  business  and  school  closures,  increased  remote  work,  stay-at-home  orders  and  other 
actions  taken  by  individuals,  governments  and  the  private  sector  to  stem  the  spread  of  the  virus  have 
significantly  reduced  global  economic  activity,  significantly  reduced  demand  for  the  petroleum  products 
that we manufacture, sell, transport and store, and contributed to increased market and oil price volatility. 
Our  refinery  utilization  and  operating  margins  and  other  aspects  of  our  business  have  been  adversely 
impacted by these developments.

During 2020, there were significant variations in the market prices of products held in our inventories. In 
each quarter of 2020, these variations required us to record either inventory valuation charges or benefits to 
reflect the valuation of our inventories at the lower of cost or market. 

Depending  on  future  movements  of  refined  product  prices,  future  inventory  valuation  adjustments  could 
have a negative or positive effect on our financial performance. In addition, a sustained period of low crude 
oil prices may also result in significant financial constraints on certain producers from which we acquire 
our crude oil, which could result in long term crude oil supply constraints for our business. Such conditions 
could  also  result  in  an  increased  risk  that  our  customers  and  other  counterparties  may  be  unable  to  fully 
fulfill their obligations in a timely manner, or at all. 

Resurgences  in  COVID-19  infections  could  result  in  the  imposition  of  new  stay-at-home  orders  or  other 
restrictions to slow the spread of the virus, which could further weaken demand for the petroleum products 
we manufacture, sell, transport and store, and could contribute to increased market and oil price volatility.

A  prolonged  period  of  economic  slowdown  or  recession,  or  a  protracted  period  of  depressed  prices  for 
crude oil or refined petroleum products, could continue to have significant and adverse consequences for 
our financial condition and the financial condition of our customers, suppliers and other counterparties, and 

20

could  diminish  our  liquidity,  trigger  additional  impairments  and  negatively  affect  our  ability  to  obtain 
adequate crude oil volumes and to market certain of our products at favorable prices, or at all.

The ultimate extent to which COVID-19 will continue to negatively affect us and our customers, suppliers 
and other counterparties will depend largely on the length and severity of the pandemic; actions taken by 
individuals,  governments  and  the  private  sector  to  stem  the  spread  of  the  virus;  general  economic 
conditions;  and  the  availability  and  widespread  distribution  and  use  of  safe  and  effective  vaccines,  all  of 
which cannot be predicted with certainty.

Our  financial  results  are  affected  by  volatile  refining  margins,  which  are  dependent  on  factors 
beyond our control.

Our operating results, cash flows, future rate of growth, the carrying value of our assets and our ability to 
execute  share  repurchases  and  continue  the  payment  of  our  base  dividend  are  highly  dependent  on  the 
margins  we  realize  on  our  refined  products.  Historically,  refining  and  marketing  margins  have  been 
volatile, and we believe they will continue to be volatile. Our margins from the sale of gasoline and other 
refined  products  are  influenced  by  a  number  of  conditions,  including  the  price  of  crude  oil.  The  price  of 
crude  oil  and  the  price  at  which  we  can  sell  our  refined  products  may  fluctuate  independently  due  to  a 
variety of regional and global market factors that are beyond our control, including:

•

•

•

•

•

•

•

•

•

worldwide and domestic supplies of and demand for crude oil and refined products; 

transportation  infrastructure  availability,  local  market  conditions  and  operation  levels  of  other 
refineries in our markets;

natural gas and electricity supply costs incurred by refineries; 

political instability, threatened or actual terrorist incidents, armed conflict or other global political 
conditions; 

local weather conditions; 

seasonality of demand in our marketing areas due to increased highway traffic in the spring and 
summer months; 

natural disasters such as hurricanes and tornadoes; 

domestic and foreign governmental regulations and taxes; and 

local, regional, national and worldwide economic conditions. 

Some of these factors can vary by region and may change quickly, adding to market volatility, while others 
may have longer-term effects. The longer-term effects of these and other factors on refining and marketing 
margins  are  uncertain.  We  purchase  our  crude  oil  and  other  refinery  feedstocks  weeks  before  we  refine 
them  and  sell  the  refined  products.  Price  level  changes  during  the  period  between  purchasing  feedstocks 
and selling the refined products from these feedstocks can have a significant effect on our financial results. 
We  also  purchase  refined  products  manufactured  by  others  for  resale  to  our  customers.  Price  changes 
during the periods between purchasing and reselling those refined products can have a material and adverse 
effect on our business, financial condition, results of operations and cash flows.

Lower refining and marketing margins have in the past, and may in the future, lead us to reduce the amount 
of refined products we produce, which may reduce our revenues, income from operations and cash flows. 
Significant  reductions  in  refining  and  marketing  margins  could  require  us  to  reduce  our  capital 
expenditures, impair the carrying value of our assets (such as property, plant and equipment, inventory or 
goodwill), and require us to re-evaluate practices regarding our repurchase activity and dividends.

Legal,  technological,  political  and  scientific  developments  regarding  emissions  and  fuel  efficiency 
may decrease demand for transportation fuels.

Developments aimed at reducing greenhouse gas emissions or increasing vehicle efficiency may decrease 
the  demand  or  increase  the  cost  for  our  transportation  fuels.  In  March  2020,  the  U.S.  Environmental 
Protection  Agency  (the  “EPA”)  and  the  U.S.  Department  of  Transportation’s  National  Highway  Traffic 
Safety  Administration  (“NHTSA”)  released  the  final  Safer  Affordable  Fuel-Efficient  (“SAFE”)  Vehicles 
Rule setting corporate average fuel economy (“CAFE”) and carbon dioxide (“CO2”) standards for model 
years 2021 through 2026 passenger cars and light trucks. The final rule increases the stringency of CAFE 
and CO2 emission standards by 1.5 percent each year from model years 2021 through 2026. The rule has 
been  challenged  in  court  and  could  be  revised  by  the  Biden  Administration  through  notice  and  comment 
rulemaking.  In  addition,  California’s  governor  issued  an  executive  order  requiring  sales  of  all  new 
passenger  vehicles  in  the  state  be  zero-emission  by  2035.  Other  states  have,  or  may  issue,  zero-emission 

21

vehicle mandates. Future developments involving climate change and environmental laws and regulations 
may require heightened fuel efficiency standards. 

Government efforts to steer the public toward non-petroleum-based fuel dependent modes of transportation 
may  foster  a  negative  perception  toward  transportation  fuels  or  increase  costs  for  our  products.  New 
technologies that increase fuel efficiency or offer alternative vehicle power sources and the proliferation of 
alternative-fuel  vehicles  (i.e.,  vehicles  that  do  not  use  petroleum-based  transportation  fuels  or  that  are 
powered by hybrid engines) may result in decreased demand for petroleum-based transportation fuel. These 
developments  could  have  a  material  and  adverse  effect  on  our  business,  financial  condition,  results  of 
operations and cash flows.

Our operations are subject to business interruptions and casualty losses, which could materially and 
adversely affect our operations, financial condition, results of operations and cash flows.

Our  operations  are  subject  to  business  interruptions,  such  as  scheduled  and  unscheduled  refinery 
turnarounds, unplanned maintenance, explosions, fires, refinery or pipeline releases, power outages, severe 
weather, labor disputes, acts of terrorism, or other natural or man-made disasters. The inability to operate 
one or more of our facilities due to any of these events could significantly impair our ability to manufacture 
our products. 

Explosions,  fires,  refinery  or  pipeline  releases,  product  quality  or  other  incidents  may  result  in  serious 
personal  injury  or  loss  of  human  life,  significant  damage  to  property  and  equipment,  environmental 
pollution,  impairment  of  operations  and  substantial  losses  to  us.  We  have  experienced  certain  of  these 
incidents in the past. For assets located near populated areas, the level of damage resulting from these risks 
could be greater.

In addition, we operate in and adjacent to environmentally sensitive waters where tanker, pipeline, rail car 
and refined product transportation and storage operations are closely regulated by federal, state and local 
agencies  and  monitored  by  environmental  interest  groups.  Certain  of  our  refineries  receive  crude  oil  and 
other feedstocks by tanker or barge. MPLX operates a fleet of boats and barges to transport light products, 
heavy oils, crude oil, renewable fuels, chemicals and feedstocks to and from refineries and terminals owned 
by MPC. Transportation and storage of crude oil, other feedstocks and refined products over and adjacent 
to  water  involves  inherent  risk  and  subjects  us  to  the  provisions  of  the  OPA-90  and  state  laws  in  U.S. 
coastal  and  Great  Lakes  states  and  states  bordering  inland  waterways  on  which  we  operate,  as  well  as 
international  laws  in  the  jurisdictions  in  which  we  operate.  If  we  are  unable  to  promptly  and  adequately 
contain  any  accident  or  discharge  involving  tankers,  pipelines,  rail  cars  or  above  ground  storage  tanks 
transporting  or  storing  crude  oil,  other  feedstocks  or  refined  products,  we  may  be  subject  to  substantial 
liability. In addition, the service providers contracted to aid us in a discharge response may be unavailable 
due to weather conditions, governmental regulations or other local or global events. 

Damages  resulting  from  an  incident  involving  any  of  our  assets  or  operations  may  result  in  our  being 
named  as  a  defendant  in  one  or  more  lawsuits  asserting  potentially  substantial  claims  or  in  our  being 
assessed potentially substantial fines by governmental authorities.

We rely on the performance of our information technology systems, and the interruption or failure of 
any  information  technology  system,  including  an  interruption  or  failure  due  to  a  cybersecurity 
breach,  could  have  an  adverse  effect  on  our  business,  financial  condition,  results  of  operations  and 
cash flows.

We  are  heavily  dependent  on  our  information  technology  systems  (and  those  of  our  third-party  business 
partners, whether cloud-based or hosted on proprietary servers), including our network infrastructure and 
cloud applications, for the safe and effective operation of our business. We rely on such systems to process, 
transmit  and  store  electronic  information,  including  financial  records  and  personally  identifiable 
information such as employee, customer, investor and payroll data, and to manage or support a variety of 
business  processes,  including  our  supply  chain,  pipeline  operations,  gathering  and  processing  operations, 
retail sales, credit card payments and authorizations at our retail outlets, financial transactions, banking and 
numerous  other  processes  and  transactions.  Our  systems  and  infrastructure  are  subject  to  damage  or 
interruption from a number of potential sources including natural disasters, malware, power failures, cyber-
attacks  and  other  events.  We  also  face  various  other  cybersecurity  threats  from  criminal  hackers  and 
employee malfeasance, including threats to gain unauthorized access to our computer network and systems 
or render data or systems unusable. 

22

Our cybersecurity protections, infrastructure protection technologies, disaster recovery plans and employee 
training may not be sufficient to defend us against all unauthorized attempts to access our information. We 
have been and may in the future be subject to attempts to gain unauthorized access to our computer network 
and systems. To date, the impacts of prior events have not had a material adverse effect on us.

Any  cybersecurity  incident  involving  our  information  technology  systems  or  those  of  our  third-party 
business partners could result in theft, destruction, loss, misappropriation or release of confidential financial 
and  other  data,  intellectual  property,  customer  awards  or  loyalty  points;  give  rise  to  remediation  or  other 
expenses;  expose  us  to  liability  under  federal  and  state  laws;  reduce  our  customers’  willingness  to  do 
business with us; disrupt the services we provide to customers; and subject us to litigation and legal liability 
under federal and state laws. Any of such results could have a material and adverse effect on our reputation, 
business, financial condition, results of operations and cash flows.

Competition in our industry is intense, and very aggressive competition could adversely impact our 
business.

We compete with a broad range of refining and marketing companies, including certain multinational oil 
companies. Competitors with integrated operations with exploration and production resources and broader 
access to resources may be better able to withstand volatile market conditions and to bear the risks inherent 
in the refining industry. For example, competitors that engage in exploration and production of crude oil 
may be better positioned to withstand periods of depressed refining margins or feedstock shortages.

We have agreed to sell Speedway to 7-Eleven. Nevertheless, pending closing of the Speedway sale, which 
remains subject to customary closing conditions and the receipt of regulatory approvals, we still face strong 
competition  in  the  market  for  the  retail  sale  of  transportation  fuels  and  merchandise.  Our  competitors 
include outlets owned or operated by fully integrated major oil companies or their dealers or jobbers, and 
other well-recognized national or regional retail outlets, often selling transportation fuels and merchandise 
at  very  competitive  prices.  Non-traditional  transportation  fuel  retailers,  such  as  supermarkets,  club  stores 
and  mass  merchants,  may  be  better  able  to  withstand  volatile  market  conditions  or  levels  of  low  or  no 
profitability in the retail segment of the market. These retailers may use promotional pricing or discounts, 
both at the pump and in the store, to encourage in-store merchandise sales, which could in turn pressure us 
to  offer  similar  discounts.  Additionally,  the  loss  of  market  share  by  our  convenience  stores  to  these  and 
other retailers relating to either transportation fuels or merchandise could have a material adverse effect on 
our business, financial condition, results of operations and cash flows.

We  are  subject  to  interruptions  of  supply  and  increased  costs  as  a  result  of  our  reliance  on  third-
party transportation of crude oil and refined products.

We utilize the services of third parties to transport crude oil and refined products to and from our refineries. 
In addition to our own operational risks, we could experience interruptions of supply or increases in costs to 
deliver refined products to market if the ability of the pipelines, railways or vessels to transport crude oil or 
refined products is disrupted because of weather events, accidents, governmental regulations or third-party 
actions. 

In  particular,  pipelines  or  railroads  provide  a  nearly  exclusive  form  of  transportation  of  crude  oil  to,  or 
refined products from, some of our refineries. A prolonged interruption, material reduction or cessation of 
service of such a pipeline or railway, whether due to private party or governmental action or other reason, 
or  any  other  prolonged  disruption  of  the  ability  of  the  trucks,  pipelines,  railways  or  vessels  to  transport 
crude oil or refined products to or from one or more of our refineries, could have a material adverse effect 
on our business, financial condition, results of operations and cash flows.

A significant decrease in oil and natural gas production in MPLX’s areas of operation may adversely 
affect MPLX’s business, financial condition, results of operations and cash available for distribution 
to its unitholders, including MPC.

A significant portion of MPLX’s operations is dependent on the continued availability of natural gas and 
crude  oil  production.  The  production  from  oil  and  natural  gas  reserves  and  wells  owned  by  its  producer 
customers  will  naturally  decline  over  time,  which  means  that  MPLX’s  cash  flows  associated  with  these 
wells  will  also  decline  over  time.  To  maintain  or  increase  throughput  levels  and  the  utilization  rate  of 
MPLX’s facilities, MPLX must continually obtain new oil, natural gas, NGL and refined product supplies, 
which depend in part on the level of successful drilling activity near its facilities, its ability to compete for 
volumes from successful new wells and its ability to expand its system capacity as needed.

23

We  have  no  control  over  the  level  of  drilling  activity  in  the  areas  of  MPLX’s  operations,  the  amount  of 
reserves associated with the wells or the rate at which production from a well will decline. In addition, we 
have no control over producers or their production decisions, which are affected by demand, prevailing and 
projected energy prices, drilling costs, operational challenges, access to downstream markets, the level of 
reserves,  geological  considerations,  governmental  regulations  and  the  availability  and  cost  of  capital. 
Reductions  in  exploration  or  production  activity  in  MPLX’s  areas  of  operations  could  lead  to  reduced 
throughput on its pipelines and utilization rates of its facilities.

Decreases in energy prices can decrease drilling activity, production rates and investments by third parties 
in the development of new oil and natural gas reserves. The prices for oil, natural gas and NGLs depend 
upon  factors  beyond  our  control,  including  global  and  local  demand,  production  levels,  changes  in 
interstate  pipeline  gas  quality  specifications,  imports  and  exports,  seasonality  and  weather  conditions, 
economic and political conditions domestically and internationally and governmental regulations. Sustained 
periods of low prices could result in producers deciding to limit their oil and gas drilling operations, which 
could substantially delay the production and delivery of volumes of oil, natural gas and NGLs to MPLX’s 
facilities and adversely affect their revenues and cash available for distribution to us. 

This impact may also be exacerbated due to the extent of MPLX’s commodity-based contracts, which are 
more directly impacted by changes in natural gas and NGL prices than its fee-based contracts due to frac 
spread  exposure  and  may  result  in  operating  losses  when  natural  gas  becomes  more  expensive  on  a  Btu 
equivalent basis than NGL products. In addition, the purchase and resale of natural gas and NGLs in the 
ordinary  course  exposes  our  Midstream  operations  to  volatility  in  natural  gas  or  NGL  prices  due  to  the 
potential  difference  in  the  time  of  the  purchases  and  sales  and  the  potential  difference  in  the  price 
associated  with  each  transaction,  and  direct  exposure  may  also  occur  naturally  as  a  result  of  production 
processes.  Also,  the  significant  volatility  in  natural  gas,  NGL  and  oil  prices  could  adversely  impact 
MPLX’s  unit  price,  thereby  increasing  its  distribution  yield  and  cost  of  capital.  Such  impacts  could 
adversely impact MPLX’s ability to execute its long‑term organic growth projects, satisfy obligations to its 
customers  and  make  distributions  to  unitholders  at  intended  levels,  and  may  also  result  in  non-cash 
impairments of long-lived assets or goodwill or other-than-temporary non-cash impairments of our equity 
method investments.

Severe  weather  events  and  other  climate  conditions  may  adversely  affect  our  facilities  and  ongoing 
operations.

Our facilities are subject to potential acute physical risks, such as floods, hurricane-force winds, wildfires 
and snowstorms, and potential chronic physical risks, such as sea-level rise or water shortages. If any such 
events were to occur, they could have an adverse effect on our assets and operations. We have incurred and 
will  continue  to  incur  additional  costs  to  protect  our  assets  and  operations  from  such  physical  risks  and 
employ the evolving technologies and processes available to mitigate such risks. To the extent such severe 
weather  events  or  other  climate  conditions  increase  in  frequency  and  severity,  we  may  be  required  to 
modify  operations  and  incur  costs  that  could  materially  and  adversely  affect  our  business,  financial 
condition, results of operations and cash flows.

We  are  subject  to  risks  arising  from  our  operations  outside  the  United  States  and  generally  to 
worldwide political and economic developments.

We operate and sell some of our products outside the United States, particularly in Mexico, South America 
and  Asia.  Our  business,  financial  condition,  results  of  operations  and  cash  flows  could  be  negatively 
impacted by disruptions in any of these markets, including economic instability, restrictions on the transfer 
of funds, duties and tariffs, transportation delays, difficulty in enforcing contractual provisions, import and 
export controls, changes in governmental policies, labor unrest, security issues involving key personnel and 
changing regulatory and political environments. Global outbreaks of infectious diseases, such as the current 
COVID-19  pandemic,  could  affect  demand  for  refined  products  and  economic  conditions  generally.  In 
addition, if trade relationships deteriorate with these countries, if existing trade agreements are modified or 
terminated,  if  new  economic  sanctions  relevant  to  such  jurisdictions  are  passed  or  if  taxes,  border 
adjustments or tariffs make trading with these countries more costly, it could have a material adverse effect 
on our business, financial condition, results of operations and cash flows.

We are required to comply with U.S. and international laws and regulations, including those involving anti-
bribery,  anti-corruption  and  anti-money  laundering.  For  example,  the  Foreign  Corrupt  Practices  Act  and 
similar laws and regulations prohibit improper payments to foreign officials for the purpose of obtaining or 
retaining  business  or  gaining  any  business  advantage.  Our  compliance  policies  and  programs  mandate 

24

compliance  with  all  applicable  anti-corruption  laws  but  may  not  be  completely  effective  in  ensuring  our 
compliance. Our training and compliance program and our internal control policies and procedures may not 
always protect us from violations committed by our employees or agents. Actual or alleged violations of 
these laws could disrupt our business and cause us to incur significant legal expenses, and could result in a 
material adverse effect on our reputation, business, financial condition, results of operations and cash flows.

More broadly, political and economic factors in global markets could impact crude oil and other feedstock 
supplies and could have a material adverse effect on us in other ways. Hostilities in the Middle East or the 
occurrence or threat of future terrorist attacks could adversely affect the economies of the U.S. and other 
developed countries. A lower level of economic activity could result in a decline in energy consumption, 
which could cause our revenues and margins to decline and limit our future growth prospects. These risks 
could lead to increased volatility in prices for refined products, NGLs and natural gas. Additionally, these 
risks could increase instability in the financial and insurance markets and make it more difficult or costly 
for us to access capital and to obtain the insurance coverage that we consider adequate. Additionally, tax 
policy, legislative or regulatory action and commercial restrictions could reduce our operating profitability. 
For example, the U.S. government could prevent or restrict exports of refined products, NGLs, natural gas 
or the conduct of business in or with certain foreign countries. In addition, foreign countries could restrict 
imports, investments or commercial transactions.

Our  investments  in  joint  ventures  could  be  adversely  affected  by  our  reliance  on  our  joint  venture 
partners  and  their  financial  condition,  and  our  joint  venture  partners  may  have  interests  or  goals 
that are inconsistent with ours.

We conduct some of our operations through joint ventures in which we share control over certain economic 
and  business  interests  with  our  joint  venture  partners.  Our  joint  venture  partners  may  have  economic, 
business  or  legal  interests  or  goals  that  are  inconsistent  with  our  goals  and  interests  or  may  be  unable  to 
meet their obligations. Failure by us, or an entity in which we have an interest, to adequately manage the 
risks associated with any acquisitions or joint ventures could have a material adverse effect on the financial 
condition  or  results  of  operations  of  our  joint  ventures  and  adversely  affect  our  reputation,  business, 
financial condition, results of operations and cash flows.

Terrorist attacks aimed at our facilities or that impact our customers or the markets we serve could 
adversely affect our business.

Refining,  gathering  and  processing,  pipeline  and  terminal  infrastructure,  and  other  energy  assets,  may  be 
future targets of terrorist organizations. Any terrorist attack on our facilities, those of our customers and, in 
some cases, those of other energy assets, could have a material adverse effect on our business. Similarly, 
any future terrorist attacks that severely disrupt the markets we serve could materially and adversely affect 
our results of operations, financial position and cash flows.

Financial Risks

We  have  significant  debt  obligations;  therefore,  our  business,  financial  condition,  results  of 
operations and cash flows could be harmed by a deterioration of our credit profile or downgrade of 
our credit ratings, a decrease in debt capacity or unsecured commercial credit available to us, or by 
factors adversely affecting credit markets generally.

At December 31, 2020, our total debt obligations for borrowed money and finance lease obligations were 
$32.17  billion,  including  $20.54  billion  of  obligations  of  MPLX  and  its  subsidiaries  and  $130  million  of 
obligations of Speedway. We may incur substantial additional debt obligations in the future.

Our  indebtedness  may  impose  various  restrictions  and  covenants  on  us  that  could  have  material  adverse 
consequences, including:

•

•

•
•
•

increasing our vulnerability to changing economic, regulatory and industry conditions; 

limiting our ability to compete and our flexibility in planning for, or reacting to, changes in our 
business and the industry; 
limiting our ability to pay dividends to our stockholders; 
limiting our ability to borrow additional funds; and 
requiring us to dedicate a substantial portion of our cash flow from operations to payments on our 
debt, thereby reducing funds available for working capital, capital expenditures, acquisitions, share 
repurchases, dividends and other purposes. 

25

A decrease in our debt or commercial credit capacity, including unsecured credit extended by third-party 
suppliers, or a deterioration in our credit profile could increase our costs of borrowing money and limit our 
access to the capital markets and commercial credit. Our credit rating is determined by independent credit 
rating  agencies.  We  cannot  provide  assurance  that  any  of  our  credit  ratings  will  remain  in  effect  for  any 
given period of time or that a rating will not be lowered or withdrawn entirely by a rating agency if, in its 
judgment, circumstances so warrant. The planned Speedway sale could be a factor causing or contributing 
to a future determination by one or more of the rating agencies to lower our credit rating. Any changes in 
our credit capacity or credit profile could materially and adversely affect our business, financial condition, 
results of operations and cash flows.

We have a trade receivables securitization facility that provides liquidity of up to $750 million depending 
on the amount of eligible domestic trade accounts receivables outstanding. In periods of lower prices, we 
may not have sufficient eligible accounts receivables to support full availability of this facility.

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

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

The  expected  phase  out  of  LIBOR  could  impact  the  interest  rates  paid  on  our  variable  rate 
indebtedness and could cause our interest expense to increase. 

A portion of our borrowing capacity and outstanding indebtedness bears interest at a variable rate based on 
LIBOR. The ICE Benchmark Administration Limited (“ICE”) announced that it will cease calculating and 
publishing  all  USD  LIBOR  tenors  on  June  30,  2023  and  cease  calculating  and  publishing  certain  USD 
LIBOR tenors on December 31, 2021. Further, U.K. and U.S. regulatory authorities have recently issued 
statements encouraging banks to cease entering into new USD LIBOR based loans as soon as possible and 
by no later than December 31, 2021 and to continue to transition away from USD LIBOR based loans in 
preparation  of  ICE  ceasing  to  calculate  and  public  LIBOR  based  rates  on  June  30,  2023.  These 
developments may cause fluctuations in LIBOR rates and pricing of USD LIBOR based loans that are not 
transitioned to a new benchmark rate. 

The  agreements  that  govern  our  variable  rate  indebtedness  contain  customary  transition  and  fallback 
provisions  in  contemplation  of  the  cessation  of  LIBOR.  Nevertheless,  at  this  time,  it  is  not  possible  to 
predict the effect that these developments, any discontinuance, modification or other reforms to LIBOR or 
any  other  reference  rate,  or  the  establishment  of  alternative  reference  rates  may  have  on  LIBOR,  other 
benchmarks  or  floating  rate  indebtedness.  Uncertainty  as  to  the  nature  of  such  potential  discontinuance, 
modification, alternative reference rates or other reforms may materially adversely affect the trading market 
for  securities  linked  to  such  benchmarks.  Furthermore,  the  use  of  alternative  reference  rates  or  other 
reforms could cause the market value of, the applicable interest rate on and the amount of interest paid on 
our  floating  rate  indebtedness  to  be  materially  different  than  expected  and  could  materially  adversely 
impact  our  ability  to  refinance  such  floating  rate  indebtedness  or  raise  future  indebtedness  on  a  cost 
effective basis.

We may incur losses and additional costs as a result of our forward-contract activities and derivative 
transactions.

We currently use commodity derivative instruments, and we expect to continue their use in the future. If the 
instruments we use to hedge our exposure to various types of risk are not effective, we may incur losses. 
Derivative transactions involve the risk that counterparties may be unable to satisfy their obligations to us. 
The  risk  of  counterparty  default  is  heightened  in  a  poor  economic  environment.  In  addition,  we  may  be 
required to incur additional costs in connection with future regulation of derivative instruments to the extent 
it is applicable to us.

We do not insure against all potential losses, and, therefore, our business, financial condition, results 
of operations and cash flows could be adversely affected by unexpected liabilities and increased costs.

We maintain insurance coverage in amounts we believe to be prudent against many, but not all, potential 
liabilities  arising  from  operating  hazards.  Uninsured  liabilities  arising  from  operating  hazards  such  as 
explosions,  fires,  refinery  or  pipeline  releases,  cybersecurity  breaches  or  other  incidents  involving  our 

26

assets or operations, could reduce the funds available to us for capital and investment spending and could 
have  a  material  adverse  effect  on  our  business,  financial  condition,  results  of  operations  and  cash  flows. 
Historically,  we  also  have  maintained  insurance  coverage  for  physical  damage  and  resulting  business 
interruption to our major facilities, with significant self-insured retentions. In the future, we may not be able 
to maintain insurance of the types and amounts we desire at reasonable rates.

We  have  recorded  goodwill  and  other  intangible  assets  that  could  become  further  impaired  and 
result in material non-cash charges to our results of operations.

We accounted for the Andeavor and other acquisitions using the acquisition method of accounting, which 
requires  that  the  assets  and  liabilities  of  the  acquired  business  be  recorded  to  our  balance  sheet  at  their 
respective  fair  values  as  of  the  acquisition  date.  Any  excess  of  the  purchase  consideration  over  the  fair 
value of the acquired net assets is recognized as goodwill.

As of December 31, 2020, our balance sheet reflected $8.3 billion and $2.4 billion of goodwill and other 
intangible  assets,  respectively.  In  2020,  we  recorded  approximately  $7.4  billion  and  $177  million  in 
goodwill and other intangible asset impairment expense, respectively. To the extent the value of goodwill 
or  intangible  assets  becomes  further  impaired,  we  may  be  required  to  incur  additional  material  non-cash 
charges  relating  to  such  impairment.  Our  operating  results  may  be  significantly  impacted  from  both  the 
impairment and the underlying trends in the business that triggered the impairment.

Large  capital  projects  can  take  years  to  complete,  and  market  conditions  could  deteriorate 
significantly  between  the  project  approval  date  and  the  project  startup  date,  negatively  impacting 
project returns. 

We have several large capital projects underway, including the activities associated with the conversion of 
the  Martinez  refinery  to  a  renewable  diesel  facility.  Delays  in  completing  capital  projects  or  making 
required  changes  or  upgrades  to  our  facilities  could  subject  us  to  fines  or  penalties  as  well  as  affect  our 
ability  to  supply  certain  products  we  produce.  Such  delays  or  cost  increases  may  arise  as  a  result  of 
unpredictable factors, many of which are beyond our control, including:

•
•
•
•

•

denials of, delays in receiving, or revocations of requisite regulatory approvals or permits;
unplanned increases in the cost of construction materials or labor;
disruptions in transportation of components or construction materials;
adverse  weather  conditions,  natural  disasters  or  other  events  (such  as  equipment  malfunctions, 
explosions, fires or spills) affecting our facilities, or those of vendors or suppliers;
shortages of sufficiently skilled labor, or labor disagreements resulting in unplanned work 
stoppages;

• market-related increases in a project’s debt or equity financing costs; 
•
•

nonperformance by, or disputes with, vendors, suppliers, contractors or subcontractors; and
delays due to citizen, state or local political or activist pressure.

Any  one  or  more  of  these  factors  could  have  a  significant  impact  on  our  ongoing  capital  projects.  If  we 
were unable to make up the delays associated with such factors or to recover the related costs, or if market 
conditions  change,  it  could  materially  and  adversely  affect  our  business,  financial  condition,  results  of 
operations and cash flows.

Legal and Regulatory Risks

We  expect  to  continue  to  incur  substantial  capital  expenditures  and  operating  costs  to  meet  the 
requirements of evolving environmental or other laws or regulations. Future environmental laws and 
regulations may impact our current business plans and reduce demand for our products.

Our  business  is  subject  to  numerous  environmental  laws  and  regulations.  These  laws  and  regulations 
continue to increase in both number and complexity and affect our business. Laws and regulations expected 
to become more stringent relate to the following:

•
•
•
•
•
•

the emission or discharge of materials into the environment,
solid and hazardous waste management,
the regulatory classification of materials currently or formerly used in our business,
pollution prevention,
greenhouse gas emissions,
climate change,

27

•

•

•

•

•

characteristics and composition of transportation fuels, including the quantity of renewable fuels 
that must be blended into transportation fuels,

public and employee safety and health, 

permitting,

inherently safer technology, and

facility security.

The  specific  impact  of  laws  and  regulations,  and  their  enforcement,  on  us  and  our  competitors  may  vary 
depending on a number of factors, including the age and location of operating facilities, marketing areas, 
crude oil and feedstock sources, production processes and subsequent judicial interpretation of such laws 
and regulations. We have incurred and will continue to incur substantial capital, operating and maintenance, 
and  remediation  expenditures  to  modify  operations,  install  pollution  control  equipment,  perform  site 
cleanups  or  curtail  operations.  We  may  also  face  liability  for  personal  injury,  property  damage,  natural 
resource  damage  or  clean-up  costs  due  to  alleged  contamination  and/or  exposure  to  chemicals  or  other 
regulated  materials,  such  as  various  perfluorinated  compounds, 
including  perfluorooctanoate, 
perfluorooctane sulfonate, perfluorohexane sulfonate, or other per-and polyfluoroalkyl substances, benzene, 
MTBE  and  petroleum  hydrocarbons,  at  or  from  our  facilities.  Such  expenditures  could  materially  and 
adversely affect our business, financial condition, results of operations and cash flows.

Increased regulation of hydraulic fracturing and other oil and gas production activities could result 
in reductions or delays in U.S. production of crude oil and natural gas, which could adversely affect 
our results of operations and financial condition.

While  we  do  not  conduct  hydraulic  fracturing  operations,  we  do  provide  gathering,  processing  and 
fractionation  services  with  respect  to  natural  gas  and  natural  gas  liquids  produced  by  our  customers  as  a 
result  of  such  operations.  Our  refineries  are  also  supplied  in  part  with  crude  oil  produced  from 
unconventional  oil  shale  reservoirs.  A  range  of  federal,  state  and  local  laws  and  regulations  currently 
govern or, in some cases, prohibit, hydraulic fracturing in some jurisdictions. Stricter laws, regulations and 
permitting processes may be enacted in the future. For example, President Biden has suspended new oil and 
gas permitting on public lands and properties, and has proposed modifying royalties to account for climate 
costs.  If  these  or  other  federal,  state  and  local  legislation  and  regulatory  initiatives  relating  to  hydraulic 
fracturing or other oil and gas production activities are enacted or expanded, such efforts could impede oil 
and gas production, increase producers’ cost of compliance, and result in reduced volumes available for our 
midstream assets to gather, process and fractionate.

Climate  change  and  greenhouse  gas  emission  regulation  could  affect  our  operations,  energy 
consumption patterns and regulatory obligations, any of which could affect our results of operations 
and financial condition.

Currently,  multiple  legislative  and  regulatory  measures  to  address  greenhouse  gas  (including  carbon 
dioxide,  methane  and  nitrous  oxides)  and  other  emissions  are  in  various  phases  of  consideration, 
promulgation  or  implementation.  These  include  actions  to  develop  international,  federal,  regional  or 
statewide programs, which could require reductions in our greenhouse gas or other emissions, establish a 
carbon  tax  and  decrease  the  demand  for  refined  products.  Requiring  reductions  in  these  emissions  could 
result in increased costs to (i) operate and maintain our facilities, (ii) install new emission controls at our 
facilities and (iii) administer and manage any emissions programs, including acquiring emission credits or 
allotments.

For  example,  in  2017,  the  California  state  legislature  adopted  AB  398,  which  provides  direction  and 
parameters on utilizing cap and trade after 2020 to meet the 40 percent reduction target from 1990 levels by 
2030 specified in SB 32. Compliance with the cap and trade program is demonstrated through a market-
based credit system. Additionally, the CARB is now exploring the potential for additional greenhouse gas 
reductions  by  2045  via  a  yet  undefined  carbon  neutrality  standard.  Other  states  are  proposing,  or  have 
already  promulgated,  low  carbon  fuel  standards  or  similar  initiatives  to  reduce  emissions  from  the 
transportation sector. If we are unable to pass the costs of compliance on to our customers, sufficient credits 
are unavailable for purchase, we have to pay a significantly higher price for credits, or if we are otherwise 
unable  to  meet  our  compliance  obligation,  our  financial  condition  and  results  of  operations  could  be 
adversely affected.

Regional and state climate change and air emissions goals and regulatory programs are complex, subject to 
change  and  considerable  uncertainty  due  to  a  number  of  factors  including  technological  feasibility,  legal 
challenges  and  potential  changes  in  federal  policy.  Increasing  concerns  about  climate  change  and  carbon 

28

intensity  have  also  resulted  in  societal  concerns  and  a  number  of  international  and  national  measures  to 
limit greenhouse gas emissions. Additional stricter measures and investor pressure can be expected in the 
future and any of these changes may have a material adverse impact on our business or financial condition.

International  climate  change-related  efforts,  such  as  the  2015  United  Nations  Conference  on  Climate 
Change, which led to the creation of the Paris Agreement, may impact the regulatory framework of states 
whose  policies  directly  influence  our  present  and  future  operations.  Though  the  United  States  had 
withdrawn from the Paris Agreement, President Biden issued an executive order recommitting the United 
States  to  the  Paris  Agreement  on  January  20,  2021.  President  Biden  also  issued  an  Executive  Order  on 
climate  change  in  which  he  announced  putting  the  U.S.  on  a  path  to  achieve  net-zero  carbon  emissions, 
economy-wide,  by  2050.  The  Executive  Order  also  calls  for  the  federal  government  to  pause  oil  and  gas 
leasing on federal lands, reduce methane emissions from the oil and gas sector as quickly as possible, and 
requires  federal  permitting  decisions  to  consider  the  effects  of  greenhouse  gas  emissions  and  climate 
change. In a second Executive Order, President Biden reestablished a working group to develop the social 
cost of carbon and the social cost of methane. The social cost of carbon and social cost of methane can be 
used to weigh the costs and benefits of proposed regulations. A higher social cost of carbon could support 
more stringent greenhouse gas emission regulation.

The  scope  and  magnitude  of  the  changes  to  U.S.  climate  change  strategy  under  the  Biden  administration 
and  future  administrations,  however,  remain  subject  to  the  passage  of  legislation  and  interpretation  and 
action  of  federal  and  state  regulatory  bodies;  therefore,  the  impact  to  our  industry  and  operations  due  to 
greenhouse gas regulation is unknown at this time.

Energy assets and companies are subject to increasing environmental and climate-related litigation. 

Governmental  and  other  entities  in  various  U.S.  states  have  filed  lawsuits  against  coal,  gas,  oil  and 
petroleum  companies,  including  us.  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.  Additionally,  private  plaintiffs  and  government  parties  have  undertaken 
efforts  to  shut  down  energy  assets  by  challenging  operating  permits,  the  validity  of  easements  or  the 
compliance  with  easement  conditions.  For  example,  the  Dakota  Access  Pipeline,  in  which  MPLX  has  a 
minority  interest,  has  been  subject  to  litigation  in  which  plaintiffs  have  challenged  the  validity  of  an 
easement necessary for the operation of the pipeline and demanded a permanent shutdown of the pipeline. 
There remains a high degree of uncertainty regarding the ultimate outcome of these types of proceedings, as 
well as their potential effect on our business, financial condition, results of operation and cash flows.

We are subject to risks associated with societal and political pressures and other forms of opposition 
to the development, transportation and use of carbon-based fuels. Such risks could adversely impact 
our business and ability to realize certain growth strategies.

We  operate  and  develop  our  business  with  the  expectation  that  regulations  and  societal  sentiment  will 
continue  to  enable  the  development,  transportation  and  use  of  carbon-based  fuels.  However,  policy 
decisions relating to the production, refining, transportation, storage and marketing of carbon-based fuels 
are subject to political pressures and the influence and protests of environmental and other special interest 
groups. 

The approval process for storage and transportation projects has become increasingly challenging, due in 
part  to  state  and  local  concerns  related  to  pipelines,  negative  public  perception  regarding  the  oil  and  gas 
industry, and concerns regarding greenhouse gas emissions downstream of pipeline operations. In addition, 
government  disruptions  may  delay  or  halt  the  granting  and  renewal  of  permits,  licenses  and  other  items 
required by us and our customers to conduct our business. Our expansion or construction projects may not 
be completed on schedule (or at all), or at the budgeted cost. We also may be required to incur additional 
costs and expenses in connection with the design and installation of our facilities due to their location and 
the  surrounding  terrain.  We  may  be  required  to  install  additional  facilities,  incur  additional  capital  and 
operating  expenditures,  or  experience  interruptions  in  or  impairments  of  our  operations  to  the  extent  that 
the facilities are not designed or installed correctly. 

Moreover,  our  revenues  may  not  increase  immediately  upon  the  expenditure  of  funds  on  a  particular 
project.  For  instance,  if  we  build  a  new  pipeline,  the  construction  will  occur  over  an  extended  period  of 
time and we may not receive any material increases in revenues until after completion of the project, if at 
all. Delays or cost increases related to capital spending programs involving engineering, procurement and 
construction  of  facilities  (including  improvements  and  repairs  to  our  existing  facilities)  could  adversely 

29

affect  our  ability  to  achieve  forecasted  internal  rates  of  return  and  operating  results,  thereby  limiting  our 
ability to grow and generate cash flows.

Regulatory  and  other  requirements  concerning  the  transportation  of  crude  oil  and  other 
commodities by rail may cause increases in transportation costs or limit the amount of crude oil that 
we can transport by rail.

We  rely  on  a  variety  of  systems  to  transport  crude  oil,  including  rail.  Rail  transportation  is  regulated  by 
federal,  state  and  local  authorities.  New  regulations  or  changes  in  existing  regulations  could  result  in 
increased  compliance  expenditures.  For  example,  in  2015,  the  U.S.  Department  of  Transportation  issued 
new standards and regulations applicable to crude-by-rail transportation (Enhanced Tank Car Standards and 
Operational  Controls  for  High-Hazard  Flammable  Trains).  These  or  other  regulations  that  require  the 
reduction of volatile or flammable constituents in crude oil that is transported by rail, change the design or 
standards for rail cars used to transport the crude oil we purchase, change the routing or scheduling of trains 
carrying crude oil, or require any other changes that detrimentally affect the economics of delivering North 
American crude oil by rail could increase the time required to move crude oil from production areas to our 
refineries, increase the cost of rail transportation and decrease the efficiency of shipments of crude oil by 
rail within our operations. Any of these outcomes could have a material adverse effect on our business and 
results of operations.

Historic or current operations could subject us to significant legal liability or restrict our ability to 
operate.

We  currently  are  defending  litigation  and  anticipate  we  will  be  required  to  defend  new  litigation  in  the 
future.  Our  operations,  including  those  of  MPLX,  and  those  of  our  predecessors  could  expose  us  to 
litigation  and  civil  claims  by  private  plaintiffs  for  alleged  damages  related  to  contamination  of  the 
environment or personal injuries caused by releases of hazardous substances from our facilities, products 
liability, consumer credit or privacy laws, product pricing or antitrust laws or any other laws or regulations 
that apply to our operations. While an adverse outcome in most litigation matters would not be expected to 
be  material  to  us,  in  class-action  litigation,  large  classes  of  plaintiffs  may  allege  damages  relating  to 
extended  periods  of  time  or  other  alleged  facts  and  circumstances  that  could  increase  the  amount  of 
potential damages. Attorneys general and other government officials have in the past and may in the future 
pursue  litigation  in  which  they  seek  to  recover  civil  damages  from  companies  on  behalf  of  a  state  or  its 
citizens  for  a  variety  of  claims,  including  violation  of  consumer  protection  and  product  pricing  laws  or 
natural resources damages. We are defending litigation of that type and anticipate that we will be required 
to defend new litigation of that type in the future. If we are not able to successfully defend such litigation, it 
may  result  in  liability  to  our  company  that  could  materially  and  adversely  affect  our  business,  financial 
condition,  results  of  operations  and  cash  flows.  In  addition  to  substantial  liability,  plaintiffs  in  litigation 
may  also  seek  injunctive  relief  which,  if  imposed,  could  have  a  material  adverse  effect  on  our  future 
business, financial condition, results of operations and cash flows.

A portion of our workforce is unionized, and we may face labor disruptions that could materially and 
adversely affect our business, financial condition, results of operations and cash flows.

Approximately  3,771  of  our  employees  are  covered  by  collective  bargaining  agreements.  Of  these 
employees,  approximately  192  employees  at  our  St.  Paul  Park  refinery  are  covered  by  a  collective 
bargaining agreement which expired on December 31, 2020. Approximately 231 employees at our El Paso 
refinery  are  covered  by  a  collective  bargaining  agreement  scheduled  to  expire  in  April  2021. 
Approximately  2,390  employees  at  our  Anacortes,  Canton,  Catlettsburg,  Galveston  Bay,  Los  Angeles, 
Mandan, Martinez and Salt Lake City refineries are covered by collective bargaining agreements that are 
due  to  expire  on  February  1,  2022.  The  remaining  958  hourly  represented  employees  are  covered  by 
collective bargaining agreements with expiration dates ranging from 2021 to 2024. These agreements may 
be renewed at an increased cost to us. In addition, we have experienced in the past, and may experience in 
the future, work stoppages as a result of labor disagreements. For example, approximately 192 workers at 
our  St.  Paul  Park  refinery  have  been  on  strike  since  January  21,  2021.  Any  prolonged  work  stoppages 
disrupting  operations  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  results  of 
operations and cash flows.

In  addition,  California  requires  refinery  owners  to  pay  prevailing  wages  to  contract  craft  workers  and 
restricts refiners’ ability to hire qualified employees to a limited pool of applicants. Legislation or changes 
in regulations could result in labor shortages, higher labor costs, and an increased risk that contract workers 
become  joint  employees,  which  could  trigger  bargaining  issues,  and  wage  and  benefit  consequences, 
especially during critical maintenance and construction periods.

30

One  of  our  subsidiaries  acts  as  the  general  partner  of  a  master  limited  partnership,  which  may 
expose us to certain legal liabilities.

One of our subsidiaries acts as the general partner of MPLX, a master limited partnership. Our control of 
the general partner of MPLX may increase the possibility of claims of breach of fiduciary duties, including 
claims of conflicts of interest. Any liability resulting from such claims could have a material adverse effect 
on our future business, financial condition, results of operations and cash flows.

If  foreign  investment  in  us  or  MPLX  exceeds  certain  levels,  MPLX  could  be  prohibited  from 
operating  inland  river  vessels,  which  could  adversely  affect  MPLX’s  business,  financial  condition, 
results of operations and cash available for distribution to its unitholders, including MPC.

The Shipping Act of 1916 and Merchant Marine Act of 1920 (collectively, the “Maritime Laws”), generally 
require that vessels engaged in U.S. coastwise trade be owned by U.S. citizens. Among other requirements 
to establish citizenship, entities that own such vessels must be owned at least 75 percent by U.S. citizens. If 
we fail to maintain compliance with the Maritime Laws, MPLX would be prohibited from operating vessels 
in the U.S. inland waters. Such a prohibition could materially and adversely affect our business, financial 
condition, results of operations and cash flows.

Our  operations  could  be  disrupted  if  we  are  unable  to  maintain  or  obtain  real  property  rights 
required for our business.

We do not own all of the land on which certain of our assets are located, particularly our midstream assets, 
but  rather  obtain  the  rights  to  construct  and  operate  such  assets  on  land  owned  by  third  parties  and 
governmental  agencies  for  a  specific  period  of  time.  Therefore,  we  are  subject  to  the  possibility  of  more 
burdensome  terms  and  increased  costs  to  retain  necessary  land  use  if  our  leases,  rights-of-way  or  other 
property rights lapse, terminate or are reduced or it is determined that we do not have valid leases, rights-
of-way or other property rights. Any loss of or reduction in these rights, including loss or reduction due to 
legal, governmental or other actions or difficulty renewing leases, right-of-way agreements or permits on 
satisfactory terms or at all, could have a material adverse effect on our business, financial condition, results 
of operations and cash flows.

Certain  of  our  facilities  are  located  on  Native  American  tribal  lands  and  are  subject  to  various 
federal and tribal approvals and regulations, which may increase our costs and delay or prevent our 
efforts to conduct planned operations.

Various  federal  agencies  within  the  U.S.  Department  of  the  Interior,  particularly  the  Bureau  of  Indian 
Affairs,  Bureau  of  Land  Management,  and  the  Office  of  Natural  Resources  Revenue,  along  with  each 
Native American tribe, regulate natural gas and oil operations on Native American tribal lands, including 
drilling and production requirements and environmental standards. In addition, each Native American tribe 
is a sovereign nation having the right to enforce laws and regulations and to grant approvals independent 
from  federal,  state  and  local  statutes  and  regulations.  These  tribal  laws  and  regulations  include  various 
taxes,  fees,  requirements  to  employ  Native  American  tribal  members  and  other  conditions  that  apply  to 
operators  and  contractors  conducting  operations  on  Native  American  tribal  lands.  Persons  conducting 
operations on tribal lands are generally subject to the Native American tribal court system. In addition, if 
our  relationships  with  any  of  the  relevant  Native  American  tribes  were  to  deteriorate,  we  could  face 
significant risks to our ability to continue operations on Native American tribal lands. One or more of these 
factors may increase our cost of doing business on Native American tribal lands and impact the viability of, 
or prevent or delay our ability to conduct operations on such lands.

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

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

•

•

•

•

any derivative action or proceeding brought on behalf of MPC;

any action asserting a claim of breach of a fiduciary duty owed by any director or officer of MPC 
to MPC or its stockholders
any  action  asserting  a  claim  against  MPC  arising  pursuant  to  any  provision  of  the  General 
Corporation  Law  of  the  State  of  Delaware,  MPC’s  Restated  Certificate  of  Incorporation,  any 
Preferred Stock Designation or the Bylaws of MPC; or
any other action asserting a claim against MPC or any Director or officer of MPC that is governed 
by or subject to the internal affairs doctrine for choice of law purposes.

31

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

Provisions  in  our  corporate  governance  documents  could  operate  to  delay  or  prevent  a  change  in 
control of our company, dilute the voting power or reduce the value of our capital stock or affect its 
liquidity.

The existence of some provisions within our restated certificate of incorporation and amended and restated 
bylaws  could  discourage,  delay  or  prevent  a  change  in  control  of  us  that  a  stockholder  may  consider 
favorable. These include provisions:

•

•

•

•

•

•

•

•

•

•

providing that our board of directors fixes the number of members of the board; 

providing for the division of our board of directors into three classes with staggered terms; 

providing that only our board of directors may fill board vacancies; 

limiting who may call special meetings of stockholders; 

prohibiting stockholder action by written consent, thereby requiring stockholder action to be taken 
at a meeting of the stockholders; 

establishing advance notice requirements for nominations of candidates for election to our board 
of directors or for proposing matters that can be acted on by stockholders at stockholder meetings; 

establishing supermajority vote requirements for certain amendments to our restated certificate of 
incorporation; 

providing that our directors may only be removed for cause; 

authorizing a large number of shares of common stock that are not yet issued, which would allow 
our  board  of  directors  to  issue  shares  to  persons  friendly  to  current  management,  thereby 
protecting the continuity of our management, or which could be used to dilute the stock ownership 
of persons seeking to obtain control of us; and 

authorizing the issuance of “blank check” preferred stock, which could be issued by our board of 
directors to increase the number of outstanding shares and thwart a takeover attempt. 

Our  restated  certificate  of  incorporation  also  authorizes  us  to  issue,  without  the  approval  of  our 
stockholders, one or more classes or series of preferred stock having such designation, powers, preferences 
and relative, participating, optional and other special rights, including preferences over our common stock 
respecting dividends and distributions, as our board of directors generally may determine. The terms of one 
or  more  classes  or  series  of  preferred  stock  could  dilute  the  voting  power  or  reduce  the  value  of  our 
common stock. For example, we could grant holders of preferred stock the right to elect some number of 
our  board  of  directors  in  all  events  or  on  the  happening  of  specified  events  or  the  right  to  veto  specified 
transactions.  Similarly,  the  repurchase  or  redemption  rights  or  liquidation  preferences  we  could  assign  to 
holders of preferred stock could affect the residual value of our common stock.

Finally, to facilitate compliance with the Maritime Laws, our restated certificate of incorporation limits the 
aggregate percentage ownership by non-U.S. citizens of our common stock or any other class of our capital 
stock to 23 percent of the outstanding shares. We may prohibit transfers that would cause ownership of our 
common  stock  or  any  other  class  of  our  capital  stock  by  non-U.S.  citizens  to  exceed  23  percent.  Our 
restated certificate of incorporation also authorizes us to effect any and all measures necessary or desirable 
to monitor and limit foreign ownership of our common stock or any other class of our capital stock. These 
limitations could have an adverse impact on the liquidity of the market for our common stock if holders are 
unable to transfer shares to non-U.S. citizens due to the limitations on ownership by non-U.S. citizens. Any 
such  limitation  on  the  liquidity  of  the  market  for  our  common  stock  could  adversely  impact  the  market 
price of our common stock.

Strategic Transaction Risks 

Our pending sale of Speedway to 7-Eleven is subject to conditions, including certain conditions that 
may not be satisfied or completed on a timely basis, if at all. Failure to complete the Speedway sale 
could have a material and adverse effect on us. Even if completed, the Speedway sale may not achieve 
the intended benefits.

We  have  announced  our  agreement  to  sell  Speedway,  our  company-owned  and  operated  retail 
transportation fuel and convenience store business, to 7-Eleven. The sale, which is targeted for completion 
in the first quarter of 2021, is subject to customary conditions. We and 7-Eleven may be unable to satisfy 
such conditions to the closing of the sale in a timely manner or at all and, accordingly, the Speedway sale 
may be delayed or may not be completed. Failure to complete the Speedway sale could have a material and 
adverse effect on us, including by delaying our strategic and other objectives relating to the separation of 
Speedway  and  adversely  affecting  our  plans  to  use  the  proceeds  from  the  sale  to  strengthen  our  balance 
sheet and return capital to our shareholders. Even if the sale is completed, we may not realize some or all 
the expected benefits. For example, we may be unable to utilize the proceeds from the sale as anticipated or 
capture  the  value  we  expect  from  our  plans  to  strengthen  our  balance  sheet  and  return  capital  to  our 
shareholders.  Executing  the  Speedway  sale  will  require  significant  time  and  attention  from  management, 
which  could  divert  attention  from  the  management  of  our  operations  and  the  pursuit  of  our  business 
strategies.  If  the  proposed  Speedway  sale  is  completed,  our  diversification  of  revenue  sources  will 
diminish, and it is possible that our business, financial condition, results of operations and cash flows may 
be subject to increased volatility as a result.

General Risk Factors

Significant stockholders may attempt to effect changes at our company or acquire control over our 
company,  which  could  impact  the  pursuit  of  business  strategies  and  adversely  affect  our  results  of 
operations and financial condition.

Our  stockholders  may  from  time  to  time  engage  in  proxy  solicitations,  advance  stockholder  proposals  or 
otherwise  attempt  to  effect  changes  or  acquire  control  over  our  company.  Campaigns  by  stockholders  to 
effect changes at publicly traded companies are sometimes led by investors seeking to increase short-term 
stockholder value through actions such as financial restructuring, increased debt, special dividends, stock 
repurchases  or  sales  of  assets  or  the  entire  company.  Responding  to  proxy  contests  and  other  actions  by 
activist  stockholders  can  be  costly  and  time-consuming  and  could  divert  the  attention  of  our  board  of 
directors and senior management from the management of our operations and the pursuit of our business 
strategies. As a result, stockholder campaigns could adversely affect our results of operations and financial 
condition.

Future  acquisitions  will  involve  the  integration  of  new  assets  or  businesses  and  may  present 
substantial risks that could adversely affect our business, financial conditions, results of operations 
and cash flows.

Future  transactions  involving  the  addition  of  new  assets  or  businesses  will  present  potential  risks,  which 
may include, among others:

•

•

•

•

•

•
•
•

inaccurate assumptions about future synergies, revenues, capital expenditures and operating costs;

an  inability  to  successfully  integrate,  or  a  delay  in  the  successful  integration  of,  assets  or 
businesses we acquire;

a  decrease  in  our  liquidity  resulting  from  using  a  portion  of  our  available  cash  or  borrowing 
capacity under our revolving credit agreement to finance transactions;

a  significant  increase  in  our  interest  expense  or  financial  leverage  if  we  incur  additional  debt  to 
finance transactions;

the assumption of unknown environmental and other liabilities, losses or costs for which we are 
not indemnified or for which our indemnity is inadequate;
the diversion of management’s attention from other business concerns; 
the loss of customers or key employees from the acquired business; and
the  incurrence  of  other  significant  charges,  such  as  impairment  of  goodwill  or  other  intangible 
assets, asset devaluation or restructuring charges.

33

Compliance  with  and  changes  in  tax  laws  could  materially  and  adversely  impact  our  financial 
condition, results of operations and cash flows.

We are subject to extensive tax liabilities, including federal and state income taxes and transactional taxes 
such  as  excise,  sales  and  use,  payroll,  franchise,  withholding  and  property  taxes.  New  tax  laws  and 
regulations and changes in existing tax laws and regulations could result in increased expenditures by us for 
tax  liabilities  in  the  future  and  could  materially  and  adversely  impact  our  financial  condition,  results  of 
operations and cash flows.

Additionally, many tax liabilities are subject to periodic audits by taxing authorities, and such audits could 
subject us to interest and penalties.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES 

We  believe  that  our  properties  and  facilities  are  adequate  for  our  operations  and  that  our  facilities  are 
adequately maintained. See the following sections for details of our assets by segment.

REFINING & MARKETING

The  table  below  sets  forth  the  location  and  crude  oil  refining  capacity  for  each  of  our  refineries  as  of 
December 31, 2020. Refining throughput can exceed crude oil refining capacity due to the processing of 
other  charge  and  blendstocks  in  addition  to  crude  oil  and  the  timing  of  planned  turnaround  and  major 
maintenance activity.

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

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

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

If the pipeline is temporarily shut down pending completion of the EIS, MPLX would have to contribute its 
9.19 percent pro rata share of funds required to pay interest accruing on the notes and any portion of the 
principal that matures while the pipeline is shutdown. It is also expected that MPLX would contribute its 
9.19 percent pro rata share of any costs to remediate any deficiencies to reinstate the permit and/or return 
the  pipeline  into  operation.  If  the  vacatur  of  the  easement  permit  results  in  a  permanent  shutdown  of  the 
pipeline, MPLX would have to contribute its 9.19 percent pro rata share of the cost to redeem the bonds 
(including the one percent redemption premium required pursuant to the indenture governing the notes) and 
any accrued and unpaid interest. As of December 31, 2020, our maximum potential undiscounted payments 
under  the  Contingent  Equity  Contribution  Agreement  were  approximately  $230  million  and  we  had  an 
investment  of  $465  million  in  MarEn  Bakken  Company  LLC,  which  includes  our  9.19  percent  direct 
interest in Dakota Access.

Tesoro High Plains Pipeline
In  early  July  2020,  MPLX  received  a  Notification  of  Trespass  Determination  from  the  Bureau  of  Indian 
Affairs  (“BIA”)  relating  to  a  portion  of  the  Tesoro  High  Plains  Pipeline  that  crosses  the  Fort  Berthold 
Reservation in North Dakota. The notification covered the rights of way for 23 tracts of land and demanded 
the  immediate  cessation  of  pipeline  operations.  The  notification  also  assessed  trespass  damages  of 
approximately $187 million. MPLX appealed this determination, which triggered an automatic stay of the 
requested pipeline shutdown and payment. On October 29, the Assistant Secretary - Indian Affairs issued 
an  order  vacating  the  BIA’s  trespass  order  and  requiring  the  Regional  Director  for  the  BIA  Great  Plains 
Region to issue a new decision on or before December 15 covering all 34 tracts at issue. On December 15, 
the  Regional  Director  of  the  BIA  issued  a  new  trespass  notice  to  THPP  consistent  with  the  Assistant 
Secretary of Indian Affairs order vacating the prior trespass order. The new order found that THPP was in 
trespass  and  assessed  trespass  damages  of  approximately  $4MM  (including  interest).  The  order  also 
required THPP to immediately cease and desist use of the portion of the pipeline that crosses the property at 
issue. The new order was appealed, and was upheld by the Assistant Secretary - Indian Affairs. THPP has 
complied with the Regional Director’s December 15, 2020 notice. On February 12, 2021, landowners filed 
suit  in  the  U.S.  District  Court  for  the  District  of  North  Dakota,  requesting,  among  other  things,  that 
decisions by the Assistant Secretary - Indian Affairs and the Interior Board of Indian Appeals be vacated as 
to the award of damages to plaintiffs.

MPLX continues to work towards a settlement of this matter with holders of the property rights at issue. 

Environmental Proceedings

Item 103 of Regulation S-K promulgated by the SEC requires disclosure of certain environmental matters 
when  a  governmental  authority  is  a  party  to  the  proceedings  and  such  proceedings  involve  potential 
monetary sanctions, unless we reasonably believe that the matter will result in no monetary sanctions, or in 
monetary  sanctions,  exclusive  of  interest  and  costs,  of  less  than  $300,000.  The  following  matters  are 
disclosed  in  accordance  with  that  requirement.  We  do  not  currently  believe  that  the  eventual  outcome  of 
any  such  matters,  individually  or  in  the  aggregate,  could  have  a  material  adverse  effect  on  our  business, 
financial condition, results of operations or cash flows.

Martinez Refinery
We  are  currently  negotiating  the  settlement  of  141  NOVs  received  from  the  Bay  Area  Air  Quality 
Management District (“BAAQMD”). The NOVs were issued from 2011 to 2019 and allege violations of air 
quality regulations and the idled Martinez refinery’s air permit. While we are negotiating a settlement of the 
allegations with the BAAQMD through two separate enforcement actions, we cannot currently estimate the 
timing of the resolution of these matters.

On July 18, 2016, the U.S. Department of Justice (“DOJ”) lodged a complaint on behalf of the EPA and a 
Consent  Decree  in  the  U.S.  Court  for  the  Western  District  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 fourth quarter of 2019, TRMC and the United States entered into an agreement to 
amend  the  Consent  Decree  to  resolve  these  issues.  In  light  of  the  actions  to  strategically  reposition  the 
Martinez  refinery  to  a  renewable  diesel  facility,  we  are  renegotiating  the  Consent  Decree  modification. 
Subject to final approval by the court, we expect that the renegotiated Consent Decree modification will no 
longer require the installation of a Selective Catalytic Reduction system to control NOx emissions from the 
now-idled fluid catalytic cracking unit, but will result in an increased civil penalty. 

Gathering and Processing
In November 2020, we received an offer from the EPA to settle multiple alleged violations of the National 
Emission  Standards  for  Hazardous  Air  Pollutants  by  the  Chapita,  Coyote  Wash,  Island,  River  Bend  and 
Wonsits  Valley  Compressor  Stations  in  Utah.  The  proposed  settlement  consists  of  an  injunctive  relief 
package,  mitigation  project  and  proposed  penalty  in  excess  of  $300,000.  We  continue  to  negotiate  a 
settlement of the allegations and cannot currently estimate the timing of the resolution of this matter.

On October 1, 2018, we acquired Andeavor. The financial results for these operations are included in our consolidated results 
from the date of acquisition, excluding the results reclassified to discontinued operations due to the planned Speedway sale.

Earnings  for  2017  include  a  tax  benefit  of  approximately  $1.5  billion,  or  $2.93  per  diluted  share,  as  a  result  of  re-measuring 
certain net deferred tax liabilities using the lower corporate tax rate enacted in the fourth quarter of 2017.

As  a  result  of  the  agreement  to  sell  Speedway,  its  results  are  reported  separately  as  discontinued  operations  for  all  periods 
presented. Refining & Marketing intersegment sales to Speedway that were previously eliminated in consolidation are reported 
as third party sales as we will continue to supply fuel to Speedway following its disposition. 

The 2020, 2019 and 2018 periods reflect an election to present certain taxes on a net basis concurrent with our adoption of ASU 
2014-09, Revenue - Revenue from Contracts with Customers (“ASC 606”). 

Includes amounts due within one year. Excludes debt obligations of Speedway, which have been reclassified as liabilities held 
for sale.

EXECUTIVE SUMMARY

Business Update

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

This  has  in  turn  significantly  reduced  global  economic  activity,  including  a  dramatic  reduction  in  airline 
flights  and  a  decrease  in  motor  vehicle  use.  As  a  result,  there  has  been  a  decline  in  the  demand  for  the 
refined petroleum products that we manufacture and sell, which coupled with a decline in the price of crude 
oil for most of 2020 resulted in a significant decrease in the price and volume of our production and sales of 
refined petroleum products.

During 2020, there were significant variations in the market prices of products held in our inventories. In 
each quarter of 2020, these variations required us to record either inventory valuation charges or benefits to 
reflect the valuation of our inventories at the lower of cost or market.

We have been and continue to actively respond to the impacts that these matters are having on our business. 
Our response has focused on establishing three strategic short-term priorities:

Strengthen Competitive Position of Assets

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

Improve Commercial Performance

We are focused on leveraging advantaged raw material selection, new approaches in the commercial space 
to  be  more  dynamic  amidst  changing  market  conditions,  and  achieving  technology  improvements  to 
advance our commercial performance. 

Lower Cost Structure

We are committed to achieving operational excellence by reducing costs, improving efficiency, and driving 
operational improvements. In response to the pandemic, in March of 2020, we committed to immediately 
reducing our capital spending and operating expenses. We accomplished our goal of significantly reducing 
our  capital  spending  levels  by  over  $1.4  billion  from  our  initial  2020  plans.  We  also  reduced  our  2020 
forecasted operating expenses by more than our target of $950 million.

In  connection  with  these  three  strategic  short-term  priorities,  in  the  third  quarter  of  2020  we  announced 
strategic  actions  to  lay  a  foundation  for  long-term  success,  including  plans  to  optimize  our  assets  and 
structurally lower costs in 2021 and beyond. These actions included indefinitely idling the Gallup refinery, 
initiating  actions  to  strategically  reposition  the  Martinez  refinery  to  a  renewable  diesel  facility  and  the 
approval  of  an  involuntary  workforce  reduction  plan.  In  connection  with  these  strategic  actions,  we 
recorded restructuring expenses of $367 million for the year ended December 31, 2020.

49

In addition to these measures to address our operations, throughout the year we took action to address our 
liquidity as outlined below:

•

•

•

•

•

•

Share repurchases were temporarily suspended. The timing and amount of future repurchases will 
depend upon several factors, including market and business conditions.

On  April  27,  2020,  we  entered  into  an  additional  $1.0  billion  364-day  revolving  credit  facility, 
which  expires  in  2021,  to  provide  incremental  liquidity  and  financial  flexibility  during  the 
commodity  price  and  demand  downturn.  In  February  2021,  we  elected  to  terminate  this  credit 
agreement as we no longer believe the facility is necessary as an additional source for liquidity, 
and we do not intend to replace it.

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

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

On September 23, 2020, we entered into a 364-day revolving credit agreement, which provides for 
a  $1.0  billion  unsecured  revolving  credit  facility  that  matures  in  September  2021,  and  which 
replaced a similar 364-day revolving credit agreement that expired on September 28, 2020. 

At  December  31,  2020,  we  had  $6.73  billion  available  on  our  variable  credit  facilities,  net  of 
commercial paper borrowings of $1.02 billion.

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

Other Strategic Updates

The Dickinson, North Dakota, renewable fuels facility began ramping operations at the end of 2020 and is 
on-track  to  reach  full  production  by  the  end  of  the  first  quarter  of  2021.  At  full  capacity,  the  facility  is 
expected  to  produce  184  million  gallons  per  year  of  renewable  diesel  from  corn  and  soybean  oil.  MPC 
intends to sell the renewable diesel into the California market to comply with the California Low Carbon 
Fuel Standard. 

During  the  fourth  quarter  of  2020,  we  also  progressed  activities  associated  with  the  conversion  of  the 
Martinez refinery to a renewable diesel facility, including applying for permits, advancing discussions with 
feedstock  suppliers,  and  beginning  detailed  engineering  activities.  As  envisioned,  the  Martinez  facility 
would start producing approximately 260 million gallons per year of renewable diesel by the second half of 
2022, with a potential to build to full capacity of approximately 730 million gallons per year by the end of 
2023.  On February 24, 2021, MPC’s board of directors approved these plans.

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

During  the  year  ended  December  31,  2020,  1,473,843  MPLX  common  units  were  repurchased  at  an 
average cost per unit of $22.29. Total cash paid for units repurchased during the year was $33 million and 
$967 million of repurchase authorization remained outstanding on the program as of December 31, 2020.

During 2020, actions taken by various governmental authorities, individuals and companies to prevent the 
spread  of  COVID-19  through  social  distancing  restricted  travel,  many  business  operations,  public 
gatherings  and  the  overall  level  of  individual  movement  and  in-person  interaction  in  the  areas  where  we 
operate  which  impacted  demand  for  our  products.  Net  income  attributable  to  MPC  decreased  $12.46 
billion, or $19.10 per diluted share, in 2020 compared to 2019 primarily due to a loss in our Refining & 
Marketing segment, goodwill and long-lived asset impairment charges of $8.43 billion and impairments of 
equity method investments of $1.32 billion during the period primarily driven by the effects of COVID-19 
and the decline in commodity prices, and restructuring expenses of $367 million related to the idling of the 
Martinez and Gallup refineries and costs related to our announced workforce reduction. 

The  loss  from  operations  in  our  Refining  &  Marketing  segment  is  primarily  due  to  decreases  in  refined 
product sales volumes, prices and margins during 2020 and includes a charge of $561 million for the twelve 
months  ended  December  31,  2020  to  reflect  a  LIFO  liquidation  for  our  crude  oil  and  refined  product 
inventories. The costs of inventories in the historical LIFO layers which were liquidated were higher than 
current  costs,  which  resulted  in  increased  cost  of  revenues  and  decreased  income  from  operations.  These 
results were partially offset by increased income from discontinued operations, which relates to Speedway, 
in  2020  compared  to  2019  largely  due  to  higher  fuel  margins  partially  offset  by  lower  fuel  volumes.  In 
addition,  as  of  August  2,  2020,  MPC  ceased  recording  depreciation  and  amortization  for  Speedway.  See 
Item 8. Financial Statements and Supplementary Data – Note 5 for additional information on discontinued 
operations.

Refer  to  the  Results  of  Operations  section  for  a  discussion  of  financial  results  by  segment  for  the  three 
years ended December 31, 2020.

MPLX

We  received  limited  partner  distributions  of  $1.79  billion  and  $1.82  billion  from  MPLX  and  Andeavor 
Logistics LP (“ANDX”) during 2020 and 2019, respectively. 

We owned approximately 647 million MPLX common units at December 31, 2020 with a market value of 
$14.02 billion based on the December 31, 2020 closing unit price of $21.65. On January 28, 2021, MPLX 
declared a quarterly cash distribution of $0.6875 per common unit, which was paid February 12, 2021. As a 
result, MPLX made distributions totaling $714 million to its common unitholders. MPC’s portion of this 
distribution was approximately $445 million.

On  July  31,  2020,  Western  Refining  Southwest,  Inc.  (now  known  as  Western  Refining  Southwest  LLC) 
(“WRSW”), a wholly owned subsidiary of MPC, entered into a Redemption Agreement (the “Redemption 
Agreement”)  with  MPLX,  pursuant  to  which  MPLX  transferred  to  WRSW  all  of  the  outstanding 
membership interests in Western Refining Wholesale, LLC, (“WRW”) in exchange for the redemption of 
MPLX  common  units  held  by  WRSW.  The  transaction  effected  the  transfer  to  MPC  of  the  Western 
wholesale distribution business that MPLX acquired as a result of its acquisition of ANDX. Beginning in 
the  third  quarter  of  2020,  the  results  of  these  operations  are  presented  in  MPC’s  Refining  &  Marketing 
segment.

At  the  closing,  per  the  terms  of  Redemption  Agreement,  MPLX  redeemed  18,582,088  MPLX  common 
units  held  by  WRSW.  The  number  of  redeemed  units  was  calculated  by  dividing  WRW’s  aggregate 
valuation  of  $340  million  by  the  simple  average  of  the  volume  weighted  average  New  York  Stock 
Exchange  prices  of  an  MPLX  common  unit  for  the  ten  trading  days  ending  at  market  close  on  July  27, 
2020. The transaction resulted in a minor decrease in MPC’s ownership interest in MPLX.

See Item 8. Financial Statements and Supplementary Data – Note 6 for additional information on MPLX.

OVERVIEW OF SEGMENTS

Refining & Marketing

Refining  &  Marketing  segment  income  from  operations  depends  largely  on  our  Refining  &  Marketing 
margin,  refining  operating  costs,  refining  planned  turnarounds,  distribution  costs,  depreciation  expenses 
and refinery throughputs. Our total refining capacity was 2,874 mbpcd, 3,067 mbpcd and 3,021 mbpcd as 
of December 31, 2020, 2019 and 2018, respectively. 

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 

53

 
 
 
 
 
 
 
 
 
 
 
 
 
with other industry participants, we calculate Gulf Coast, Mid-Continent and West Coast crack spreads that 
we  believe  most  closely  track  our  operations  and  slate  of  products.  The  following  will  be  used  for  these 
crack-spread calculations:

•

•

•

The  Gulf  Coast  crack  spread  uses  three  barrels  of  LLS  crude  producing  two  barrels  of  USGC 
CBOB gasoline and one barrel of USGC ULSD; 

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

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

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

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

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

Crack spread based on 40 percent LLS, 40 percent WTI and 20 percent ANS with Gulf Coast, Mid-Continent and West Coast 
product pricing, respectively, and assumes all other differentials and pricing relationships remain unchanged.

Sour crude oil basket consists of the following crudes: ANS, Argus Sour Crude Index, Maya and Western Canadian Select. We 
expect approximately 51 percent of the crude processed at our refineries in 2021 will be sour crude.

Sweet  crude  oil  basket  consists  of  the  following  crudes:  Bakken,  Brent,  LLS,  WTI-Cushing  and  WTI-Midland.  We  expect 
approximately 49 percent of the crude processed at our refineries in 2021 will be sweet crude.

This  is  consumption  based  exposure  for  our  Refining  &  Marketing  segment  and  does  not  include  the  sales  exposure  for  our 
Midstream segment. 

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

•

•

•

•

•

•

•

the selling prices realized for refined products;

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

our refinery yields;

the cost of products purchased for resale; 

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

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

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

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. 
At December 31, 2020, market values for refined products exceed their cost basis and, therefore, there is no 
LCM  inventory  valuation  reserve  at  the  end  of  the  year.  Based  on  movements  of  refined  product  prices, 
future inventory valuation adjustments could have a negative effect to earnings. Such losses are subject to 
reversal in subsequent periods if prices recover.

54

 
 
 
 
Refining  &  Marketing  segment  income  from  operations  is  also  affected  by  changes  in  refining  operating 
costs  and  refining  planned  turnaround  costs  in  addition  to  committed  distribution  costs.  Changes  in 
operating  costs  are  primarily  driven  by  the  cost  of  energy  used  by  our  refineries,  including  purchased 
natural  gas,  and  the  level  of  maintenance  costs.  Refining  planned  turnarounds,  requiring  temporary 
shutdown of certain refinery operating units, are periodically performed at each refinery. Distribution costs 
primarily  include  long-term  agreements  with  MPLX,  as  discussed  below,  which  are  based  on  committed 
volumes and will negatively impact income from operations in periods when throughput or sales are lower 
or refineries are idled.

The  following  table  lists  the  refineries  that  had  significant  planned  turnaround  and  major  maintenance 
activities  for  each  of  the  last  three  years  and  only  reflects  the  activity  for  the  acquired  refineries  after 
October 1, 2018.

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

Midstream 

Our  Midstream  segment  transports,  stores,  distributes  and  markets  crude  oil  and  refined  products, 
principally  for  our  Refining  &  Marketing  segment.  The  profitability  of  our  pipeline  transportation 
operations  primarily  depends  on  tariff  rates  and  the  volumes  shipped  through  the  pipelines.  The 
profitability of our marine operations primarily depends on the quantity and availability of our vessels and 
barges.  The  profitability  of  our  light  product  terminal  operations  primarily  depends  on  the  throughput 
volumes  at  these  terminals.  The  profitability  of  our  fuels  distribution  services  primarily  depends  on  the 
sales volumes of certain refined products. The profitability of our refining logistics operations depends on 
the quantity and availability of our refining logistics assets. A majority of the crude oil and refined product 
shipments on our pipelines and marine vessels and the refined product throughput at our terminals serve our 
Refining  &  Marketing  segment  and  our  refining  logistics  assets  and  fuels  distribution  services  are  used 
solely by our Refining & Marketing segment.

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

Our Midstream segment also gathers and processes natural gas and NGLs. NGL and natural gas prices are 
volatile  and  are  impacted  by  changes  in  fundamental  supply  and  demand,  as  well  as  market  uncertainty, 
availability  of  NGL  transportation  and  fractionation  capacity  and  a  variety  of  additional  factors  that  are 
beyond  our  control.  Our  Midstream  segment  profitability  is  affected  by  prevailing  commodity  prices 
primarily as a result of processing or conditioning at our own or third‑party processing plants, purchasing 

55

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 for the years 
ended  December  31,  2020,  2019  and  2018.  These  amounts  include  the  results  of  Andeavor  from  the 
October  1,  2018  acquisition  date  forward.  This  discussion  should  be  read  in  conjunction  with  Item  8. 
Financial Statements and Supplementary Data 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

2020 Compared to 2019 

Net income (loss) attributable to MPC decreased $12.46 billion in 2020 compared to 2019 primarily due to 
impairment  expenses  for  goodwill  and  long-lived  assets  of  $8.43  billion,  impairments  of  equity  method 
investments of $1.32 billion, decreased refined product sales volumes, prices and margin, a charge of $561 
million  to  reflect  a  LIFO  liquidation  in  our  crude  oil  and  refined  product  inventories  and  restructuring 
expenses  of  $367  million.  These  changes  were  partially  offset  by  reduced  operating  costs  and  increased 
income  from  discontinued  operations,  which  represents  Speedway.  See  Segment  Results  for  additional 
information.

Total revenues and other income decreased $42.83 billion in 2020 compared to 2019 primarily due to:

•

•

•

decreased sales and other operating revenues of $41.37 billion primarily due to decreased Refining 
& Marketing segment refined product sales volumes, which decreased 513 mbpd, or 14 percent, 
and lower average refined product sales prices, which decreased $0.55 per gallon, or 31 percent, 
largely due to reduced travel and business operations associated with the COVID-19 pandemic; 

decreased income from equity method investments of $1.25 billion largely due to impairments of 
equity method investments of $1.32 billion primarily driven by the effects of COVID-19 and the 
decline in commodity prices; and 

decreased net gain on disposal of assets of $208 million mainly due to the absence of $259 million 
of  non-cash  gains  related  to  obtaining  equity  investments  in  Capline  Pipeline  Company  LLC 
(“Capline  LLC”)  and  The  Andersons  in  exchange  for  contributing  assets  in  2019.  This  decrease 
was  offset  by  net  gains  on  disposal  of  assets  in  2020  largely  due  to  the  sale  of  three  asphalt 
terminals and other Refining & Marketing assets.

Total costs and expenses decreased $26.12 billion in 2020 compared to 2019 primarily due to:

•

•

•

•

•

decreased  cost  of  revenues  of  $33.50  billion  primarily  due  to  reduced  travel  and  business 
operations associated with the COVID-19 pandemic, partially offset by increased cost of revenues 
of $561 million to reflect LIFO liquidations for our crude oil and refined product inventories. The 
costs of inventories in the historical LIFO layers liquidated were higher than current costs, which 
resulted in the LIFO liquidation charge;

impairment expense of $8.43 billion recorded in 2020 for goodwill and long-lived assets of $7.39 
billion  and  $1.03  billion,  respectively,  primarily  driven  by  the  effects  of  COVID-19  and  the 
decline in commodity prices. It also includes impairment of long-lived assets primarily related to 
the  repositioning  of  the  Martinez  refinery  compared  to  impairment  expense  of  $1.20  billion 
recorded  in  2019  primarily  related  to  MPLX  goodwill  associated  with  the  ANDX  gathering  and 
processing businesses acquired as part of the Andeavor acquisition; 

decreased selling, general and administrative expenses of $482 million mainly due to decreases in 
salaries  and  employee-related  expenses,  transaction-related  expenses,  credit  card  processing  fees 
for brand customers and contract services expenses; 

restructuring  expense  of  $367  million  related  to  the  idling  of  the  Martinez  and  Gallup  refineries 
and costs related to our announced workforce reduction. See See Item 8. Financial Statements and 
Supplementary Data – Note 4 for additional information; and

increased other taxes of $107 million primarily due to increased property and environmental taxes 
of approximately $78 million and $69 million, respectively. Property taxes increased in the current 
period mainly due to the absence of property tax refunds and tax exemptions received in 2019 and 
environmental taxes increased largely due to the reinstatement of the Oil Spill Tax in 2020, which 
was  not  in  effect  for  all  of  2019.  These  increases  were  offset  by  a  state  tax  refund  and  reduced 
payroll tax expenses.

Net interest and other financial costs increased $136 million largely due to increased MPC borrowings and 
foreign currency exchange losses and decreased interest income. We capitalized interest of $129 million in 
2020 and $158 million in 2019. See Item 8. Financial Statements and Supplementary Data – Note 22 for 
further details.

Provision  for  income  taxes  decreased  $3.21  billion  primarily  due  to  decreased  income  before  taxes  of 
$16.85  billion.  The  effective  tax  rate  of  18  percent  in  2020  is  lower  than  the  U.S.  statutory  rate  of  21 
percent, primarily due to a significant amount of our pre-tax loss consisting of non-tax deductible goodwill 
impairment  charges,  partially  offset  by  the  tax  rate  differential  resulting  from  the  expected  net  operating 

57

loss carryback provided under the Coronavirus Aid, Relief, and Economic Security Act. Additionally, our 
effective tax rate is generally benefited by our noncontrolling interest in MPLX, but this benefit was lower 
for the year ended December 31, 2020 due to goodwill and other impairment charges recorded by MPLX. 
The effective tax rate of 24 percent in 2019 is higher than the U.S. statutory rate of 21 percent, primarily 
due to permanent tax differences related to goodwill impairment and state and local tax expense, partially 
offset  by  permanent  tax  differences  related  to  net  income  attributable  to  noncontrolling  interests.  See 
Item 8. Financial Statements and Supplementary Data – Note 15 for further details.

Noncontrolling interests decreased $769 million mainly due to MPLX’s net loss primarily resulting from 
impairment expense recognized during 2020.

2019 Compared to 2018 

Net  income  attributable  to  MPC  decreased  $143  million  primarily  due  to  impairment  expense  of  $1.20 
billion and an increase in net interest and other financial costs, partially offset by a decrease in net income 
attributable  to  noncontrolling  interests  and  increased  income  from  discontinued  operations  in  2019.  See 
Segment Results for additional information.

Total revenues and other income increased $25.28 billion in 2019 compared to 2018 primarily due to:

•

•

increased  sales  and  other  operating  revenues  of  $25.06  billion  mainly  due  to  an  increase  in  our 
Refining  &  Marketing  segment  refined  product  sales  volumes,  which  increased  1,032  mbpd 
largely  due  to  the  Andeavor  acquisition  on  October  1,  2018,  partially  offset  by  lower  average 
refined product sales prices, which decreased $0.09 per gallon; and

increased net gain on disposal of assets of $272 million mainly due to $259 million of non-cash 
gains related to obtaining equity investments in Capline LLC and The Andersons in exchange for 
contributing assets in 2019. 

Total costs and expenses increased $25.50 billion in 2019 compared to 2018 primarily due to:

•

•

•

•

•

increased cost of revenues of $22.18 billion primarily due to the inclusion of costs related to the 
Andeavor operations following the acquisition;

increased  impairment  expense  of  $1.20  billion  primarily  related  to  MPLX  goodwill  associated 
with the ANDX gathering and processing businesses acquired as part of the Andeavor acquisition;

increased depreciation and amortization of $1.06 billion, primarily due to the depreciation of the 
fair value of the assets acquired in connection with the Andeavor acquisition;

increased selling, general and administrative expenses of $916 million mainly due to the inclusion 
of  costs  related  to  Andeavor  operations  following  the  acquisition  and  reflecting  MPC’s 
classification of those costs and expenses; and

increased other taxes of $155 million primarily due to the inclusion of other taxes related to the 
acquired Andeavor operations.

Net interest and other financial costs increased $236 million mainly due to debt assumed in the acquisition 
of Andeavor and increased MPLX borrowings, partially offset by a decrease in pension settlement losses of 
$44 million. We capitalized interest of $158 million in 2019 and $80 million in 2018. See Item 8. Financial 
Statements and Supplementary Data – Note 22 for further details.

Provision for income taxes on continuing operations increased $20 million primarily due to non-deductible 
goodwill impairments partially offset by decreased income from continuing operations $464 million. The 
effective tax rate of 24 percent in 2019 is higher than the U.S. statutory rate of 21 percent, primarily due to 
permanent tax differences related to goodwill impairment and state and local tax expense, partially offset 
by permanent tax differences related to net income attributable to noncontrolling interests. The effective tax 
rate  of  21  percent  in  2018  is  consistent  with  the  U.S.  statutory  rate  of  21  percent,  as  permanent  benefit 
differences  related  to  income  attributable  to  noncontrolling  interest  were  offset  by  state  and  local  tax 
expense. See Item 8. Financial Statements and Supplementary Data – Note 15 for further details.

Noncontrolling interests decreased $214 million mainly due lower MPLX net income primarily as a result 
of the $1.2 billion goodwill impairment charge recorded in 2019.

2020 Compared to 2019

Income  from  discontinued  operations,  net  of  tax,  increased  $399  million  primarily  due  to  higher  fuel 
margins  partially  offset  by  lower  fuel  volumes.  Changes  in  fuel  sales  volumes  were  primarily  due  to  the 
effects  of  the  COVID-19  pandemic  which  resulted  in  restricted  travel,  social  distancing  and  reduced 
business  operations.  In  addition,  fuel  sales  volumes  decreased  as  a  result  of  an  agreement  between 
Speedway and Pilot Travel Centers (“PTC”), effective October 1, 2019, in which PTC supplies, prices and 
sells  diesel  fuel  at  certain  Speedway  and  PTC  locations  with  both  companies  sharing  in  the  diesel  fuel 
margins. 

Beginning  August  2,  2020,  in  accordance  with  ASC  360,  Property,  Plant,  and  Equipment,  we  ceased 
recording  depreciation  and  amortization  for  Speedway’s  property,  plant  and  equipment,  finite-lived 
intangible  assets  and  right  of  use  lease  assets.  As  a  result,  Speedway  depreciation  and  amortization  was 
$244 million and $413 million for the twelve months ended December 31, 2020 and 2019, respectively.

The  Speedway  fuel  margin  increased  to  34.52  cents  per  gallon  in  2020  compared  with  24.34  cents  per 
gallon in 2019.

2019 Compared to 2018

Income from discontinued operations, net of tax, increased $133 million primarily due to higher fuel and 
merchandise margins largely related to the addition of the Andeavor retail operations. These increases were 
partially  offset  by  increases  in  operating  expenses  and  depreciation  primarily  related  to  the  locations 
acquired from Andeavor.

The  Speedway  fuel  margin  increased  to  24.34  cents  per  gallon  in  2019  compared  with  21.22  cents  per 
gallon in 2018.

The blended crack spread for the fourth quarter of 2020 is weighted 40 percent of the USGC crack spread, 40 percent of the Mid-
Continent crack spread and 20 percent of the West Coast crack spread. The blended crack spreads for the first three quarters of 
2020,  all  of  2019  and  the  fourth  quarter  of  2018  are  weighted  38  percent  of  the  USGC  crack  spread,  38  percent  of  the  Mid-
Continent crack spread and 24 percent of the West Coast crack spread. The blended crack spread for the first three quarters of 
2018 reflects the average weighting of 60 percent of the USGC crack spread and 40 percent of the Mid-Continent crack spread. 
These blends are based on MPC’s refining capacity by region in each period.

2020 Compared to 2019 
Refining & Marketing segment revenues decreased $41.16 billion primarily due to lower refined product 
sales volumes, which decreased 513 mbpd, and decreased average refined product sales prices of $0.55 per 
gallon. 

Refinery crude oil capacity utilization was 82 percent during 2020 and net refinery throughputs decreased 
529 mbpd primarily due to reducing throughputs during the COVID-19 pandemic.

Refining & Marketing segment income from operations decreased $8.05 billion primarily driven by lower 
blended crack spreads.

Refining & Marketing margin, excluding LIFO liquidation charge, was $8.96 per barrel for 2020 compared 
to  $14.77  per  barrel  for  2019.  Refining  &  Marketing  margin  is  affected  by  the  market  indicators  shown 
earlier, which use spot market values and an estimated mix of crude purchases and product sales. Based on 
the market indicators and our crude oil throughput, we estimate a net negative impact of $9.75 billion on 
Refining & Marketing margin, primarily due to lower crack spreads. Our reported Refining & Marketing 
margin  differs  from  market  indicators  due  to  the  mix  of  crudes  purchased  and  their  costs,  the  effects  of 
market  structure  on  our  crude  oil  acquisition  prices,  RIN  prices  on  the  crack  spread  and  other  items  like 
refinery yields and other feedstock variances, direct dealer fuel margin, and for 2020, a LIFO liquidation 
charge of $561 million. For 2019, the Refining & Marketing segment income from operations also reflects 
a benefit of $93 million for the biodiesel tax credit attributable to volumes blended in 2018. These factors 
had  an  estimated  net  positive  impact  on  Refining  &  Marketing  segment  income  from  operations  of

approximately $800 million, including the LIFO liquidation charge, in 2020 compared to 2019 resulting in 
a capture rate of 102 percent in 2020 and 96 percent in 2019.

For the year ended December 31, 2020, refining operating costs, excluding depreciation and amortization, 
were $5.37 billion. This was a decrease of $1.06 billion, and a per barrel increase of $0.02 due to lower 
refinery throughput, compared to the year ended December 31, 2019 as we took actions to reduce costs in 
response to the economic effects of COVID-19, including operating at lower throughput at our refineries 
and idling portions of our refining capacity. Net refinery throughput was 529 mbpd lower in 2020

Distribution costs, excluding depreciation and amortization, were $5.08 billion and $5.13 billion for 2020 
and  2019,  respectively,  and  include  fees  paid  to  MPLX  of  $3.46  billion  and  $3.22  billion  for  2020  and 
2019,  respectively.  On  a  per  barrel  basis,  distribution  costs,  excluding  depreciation  and  amortization, 
increased $0.85 primarily due to lower throughput partially offset by a decrease in costs. 

Refining  planned  turnaround  costs  increased  $92  million,  or  $0.23  per  barrel,  due  to  the  timing  of 
turnaround activity and a decrease in throughput. 

Depreciation and amortization per barrel increased by $0.38, primarily due to a decrease in throughput and 
increased costs.

We purchase RINs to satisfy a portion of our RFS2 compliance. Our expenses associated with purchased 
RINs  were  $606  million  in  2020  and  $356  million  in  2019  and  are  included  in  Refining  &  Marketing 
margin. The increase in 2020 was primarily due to higher weighted average RIN costs, partially offset by a 
decrease in our RIN obligations.

2019 Compared to 2018 
Refining & Marketing segment revenues increased $24.6 billion in 2019 compared to 2018 primarily due to 
higher  refined  product  sales  volumes,  which  increased  1,032  mbpd,  largely  due  to  the  acquisition  of 
Andeavor on October 1, 2018, partially offset by decreased average refined product sales prices of $.09 per 
gallon. 

Refinery crude oil capacity utilization was 96 percent during 2019 and net refinery throughputs increased 
838 mbpd primarily due to the refineries acquired from Andeavor.

Refining & Marketing segment income from operations increased $202 million primarily due to a full year 
of direct dealer sales and an increase in Refining & Marketing margin on a per barrel basis partially offset 
by  higher  operating,  distribution  and  depreciation  and  amortization  costs.  The  increases  in  costs  and 
expenses  were  primarily  due  to  increased  sales  and  production  volumes  following  the  Andeavor 
acquisition. 

Refining  &  Marketing  margin  was  $14.77  per  barrel  for  2019  compared  to  $14.50  per  barrel  for  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 net positive impact of $4.46 billion on Refining & Marketing margin, 
primarily due to an approximate $5.35 billion benefit from increased throughput volume, mainly attributed 
to  the  Andeavor  acquisition,  partially  offset  by  narrower  sour  and  sweet  crude  oil  differentials.  Our 
reported Refining & Marketing margin differs from market indicators due to the mix of crudes purchased 
and their costs, the effects of market structure on our crude oil acquisition prices, RIN prices on the crack 
spread and other items like refinery yields and other feedstock variances and direct dealer fuel margin. For 
2019, the Refining & Marketing segment income from operations also reflects a benefit of $93 million for 
the biodiesel tax credit attributable to volumes blended in 2018. These factors had an estimated net positive 
impact on Refining & Marketing segment income from operations of approximately $370 million in 2019 
compared to 2018 resulting in a capture rate of 96 percent in 2019 compared to 92 percent in 2018.

For the year ended December 31, 2019, refining operating costs, excluding depreciation and amortization, 
were $6.42 billion. This was an increase of $2.28 billion, and a per barrel increase of $0.67. Distribution 
costs, excluding depreciation and amortization, were $5.13 billion and $3.52 billion, and include fees paid 
to MPLX of $3.22 billion and $2.28 billion, for 2019 and 2018, respectively. This was an increase of $1.61 
billion,  or  $0.28  per  barrel.  Excluding  depreciation  and  amortization,  refining  operating  costs  and 
distribution costs increased primarily due to the inclusion of costs for the refining operations acquired from 
Andeavor.  The  per  barrel  increases,  among  other  items,  reflect  the  addition  of  Andeavor’s  West  Coast 

63

refineries,  which  generally  have  higher  operating  costs  than  other  regions  in  which  we  operate  due  to 
specific geographical location and regulatory factors.

Refining  planned  turnaround  costs  decreased  $76  million,  or  $0.15  per  barrel,  due  to  the  timing  of 
turnaround activity. 

Depreciation  and  amortization  per  barrel  increased  by  $0.13,  primarily  due  to  the  fair  value  of  assets 
acquired from Andeavor as of October 1, 2018. During 2019, we recorded a $0.01 per barrel adjustment to 
reduce depreciation and amortization, which reflects the cumulative effects related to a measurement period 
adjustment arising from the finalization of purchase accounting.

We purchase RINs to satisfy a portion of our RFS2 compliance. Our expenses associated with purchased 
RINs were $356 million in 2019 and $316 million in 2018. The increase in 2019 was primarily due to an 
increase  in  our  RIN  obligations  resulting  from  the  acquisition  of  Andeavor,  partially  offset  by  lower 
weighted average RIN costs.

propane, six percent Iso-Butane, 12 percent normal butane and 12 percent natural gasoline.

2020 Compared to 2019 
Midstream  segment  revenue  decreased  $322  million  primarily  due  to  decreased  demand  for  the  products 
that  we  produce  and  transport  due  to  the  current  macro-economic  conditions  in  addition  to  lower  natural 
gas prices.

In 2020, Midstream segment income from operations increased $114 million mainly due stable, fee-based 
earnings  in  the  current  business  environment,  contributions  from  organic  growth  projects  and  reduced 
operating expenses. 

2019 Compared to 2018 
Midstream  segment  revenue  increased  $2.10  billion  primarily  due  to  the  inclusion  of  ANDX  revenues 
subsequent to the Andeavor acquisition on October 1, 2018. On July 30, 2019, MPLX acquired ANDX. In 
addition, 2019 reflects twelve months of fees charged for fuels distribution and refining logistics services 
provided  to  our  Refining  &  Marketing  segment  following  the  February  1,  2018  dropdown  to  MPLX. 
MPLX revenues from refining logistics and fuels distribution services provided to MPC were $1.48 billion 
and $1.36 billion for the years ended December 31, 2019 and 2018, respectively. 

In 2019, Midstream segment income from operations increased $842 million largely due to contributions 
from ANDX in addition to growth across MPLX’s businesses.

segment. Corporate overhead expenses are not allocated to the Refining & Marketing segment.

2020 Compared to 2019 
Corporate expenses decreased $33 million in 2020 compared to 2019 largely due to decreased salaries and 
contract services expenses, partially offset by increased expenses due to an information systems integration 
project. 2020 and 2019 corporate expenses include expenses of $26 million and $28 million, respectively, 
which are no longer allocable to Speedway due to discontinued operations accounting. 

2019 Compared to 2018 
Corporate expenses increased $305 million in 2019 compared to 2018 largely due to the inclusion of costs 
and expenses related to Andeavor operations. 2019 and 2018 corporate expenses include expenses of $28 
million  and  $26  million,  respectively,  which  are  no  longer  allocable  to  Speedway  due  to  discontinued 
operations accounting.

2020 and 2019 includes costs incurred in connection with the Midstream strategic review and other related efforts. Both 2019 
and  2018  include  employee  severance,  retention  and  other  costs  related  to  the  acquisition  of  Andeavor.  Effective  October  1, 
2019, we have discontinued reporting Andeavor transaction-related costs as one year has passed since the acquisition and these 
costs are immaterial. Costs incurred in connection with the Speedway separation are included in discontinued operations.

2020 Compared to 2019 
Unallocated  items  include  impairment  charges  of  $9.74  billion  which  includes  $8.43  billion  related  to 
goodwill  and  long-lived  assets  and  $1.32  billion  related  to  equity  method  investments.  See  Item  8. 
Financial Statements and Supplementary Data – Note 7 for additional information.

During  2020,  we  indefinitely  idled  our  Gallup  refinery,  initiated  actions  to  strategically  reposition  our 
Martinez refinery to a renewable diesel facility and approved an involuntary workforce reduction plan. In 
connection  with  these  strategic  actions,  we  recorded  restructuring  expenses  of  $367  million  for  the  year 
ended  December  31,  2020.  See  Item  8.  Financial  Statements  and  Supplementary  Data  –  Note  4  for 
additional information.

Other unallocated items in 2020 include a favorable litigation settlement of $84 million and gain on sale of 
assets of $66 million related to the sale of three asphalt terminals and certain other Refining & Marketing 
assets. 

2019 Compared to 2018 
Unallocated items in 2019 include $259 million of non-cash gains related to obtaining equity investments 
in Capline LLC and The Andersons in exchange for contributing assets. See Item 8. Financial Statements 
and Supplementary Data – Note 17 for additional information.

In  2019,  other  unallocated  items  also  include  transaction-related  costs  of  $153  million  and  a  litigation 
reserve  adjustment  of  $22  million.  The  transaction-related  costs  recognized  during  the  year  include  the 
recognition  of  an  obligation  for  vacation  benefits  provided  to  former  Andeavor  employees  in  the  first 
quarter  as  well  as  employee  retention,  severance  and  other  costs  and  the  Midstream  strategic  review  and 
other related efforts.

Impairment charges of $1.24 billion in 2019 primarily relate to MPLX goodwill associated with the ANDX 
gathering  and  processing  businesses  acquired  as  part  of  the  Andeavor  acquisition.  See  Item  8.  Financial 
Statements and Supplementary Data – Note 19 for additional information.

Non-GAAP Financial Measures 

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

Refining & Marketing Margin
Refining  margin  is  defined  as  sales  revenue  less  the  cost  of  refinery  inputs  and  purchased  products  and 
excludes other items reflected in the table below.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

Our cash and cash equivalents balance was $415 million at December 31, 2020 compared to $1.39 billion 
at December 31, 2019, excluding $140 million and $134 million, respectively, of cash and cash equivalents 
related  to  the  discontinued  operations  of  Speedway  which  are  included  in  assets  held  for  sale.  Net  cash 
provided  by  (used  in)  operating  activities,  investing  activities  and  financing  activities  for  the  past  three 
years is presented in the following table.

Net cash provided by operating activities decreased $7.02 billion in 2020 compared to 2019, primarily due 
to a decrease in operating results and an unfavorable change in working capital of $43 million. Net cash 
provided  by  operating  activities  increased  $3.28  billion  in  2019  compared  to  2018,  primarily  due  to  an 
increase in operating results, excluding impairment expenses, and a favorable change in working capital of 
$978 million. The above changes in working capital exclude changes in short-term debt. 

For 2020, changes in working capital were a net $314 million source of cash, primarily due to the effect of 
decreases  in  energy  commodity  prices  and  inventory  and  refined  product  volumes  on  working  capital. 
Accounts  payable  decreased  primarily  due  to  lower  crude  payable  prices.  Current  receivables  decreased 
primarily due to lower crude and refined product receivable prices and refined product volumes. Inventories 
decreased mainly due to decreases in refined product, crude and materials & supplies inventories.

For 2019, changes in working capital were a net $357 million source of cash, primarily due to the effect of 
increases  in  energy  commodity  prices  and  volumes  on  working  capital.  Accounts  payable  increased 
primarily due to higher crude oil payable price and volumes. Current receivables increased primarily due to

increases in crude and refined product receivable volumes and prices. Inventories increased primarily due 
to increases in refined product and materials & supplies inventories partially offset by a decrease in crude 
inventory.

For 2018, changes in working capital were a net $621 million use of cash, primarily due to the effect of 
decreases  in  energy  commodity  prices  on  working  capital.  Accounts  payable  decreased  primarily  due  to 
lower  crude  oil  payable  prices.  Inventories  decreased  primarily  due  to  a  decrease  in  crude  and  refined 
product inventories. Current receivables decreased primarily due to lower crude oil receivable prices. All of 
these effects exclude the working capital acquired in connection with the acquisition of Andeavor.

Cash  flows  used  in  investing  activities  decreased  $3.00  billion  in  2020  compared  to  2019  and  decreased 
$1.41 billion in 2019 compared to 2018.

Cash  used  for  additions  to  property,  plant  and  equipment  was  primarily  due  to  spending  in  our 
Midstream  and  Refining  &  Marketing  segments  in  2020.  See  discussion  of  capital  expenditures 
and investments under the “Capital Spending” section.

Cash  used  for  acquisitions  of  $3.82  billion  in  2018  primarily  includes  cash  paid  to  Andeavor 
stockholders of $3.5 billion in connection with the acquisition of Andeavor on October 1, 2018.

Net investments were a use of cash of $348 million in 2020 compared to $966 million in 2019 and 
$393  million  in  2018.  Investments  in  2020  are  largely  due  to  investments  in  the  South  Texas 
Gateway  Terminal,  the  Gray  Oak  Pipeline  and  the  Whistler  Pipeline.  Investments  in  2019  are 
largely due to investments in connection with the Gray Oak Pipeline, which began initial start-up 
in  the  fourth  quarter,  the  Wink  to  Webster  Pipeline,  the  Whistler  Pipeline  and  other  Midstream 
projects. 

Cash  provided  by  disposal  of  assets  totaled  $150  million,  $47  million  and  $22  million  in  2020, 
2019  and  2018,  respectively.  The  increase  in  2020  is  mainly  due  to  the  sale  of  three  asphalt 
terminals  and  other  Refining  &  Marketing  assets.  The  increase  in  2019  is  primarily  due  to 
proceeds from the sale of assets in our Retail segment.

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

Long-term  debt  borrowings  and  repayments,  including  debt  issuance  costs,  were  a  net  $1.65 
billion  source  of  cash  in  2020  compared  to  a  $1.18  billion  source  of  cash  in  2019  and  a  $5.36 
billion source of cash in 2018. During 2020, MPC issued $2.5 billion of senior notes, redeemed 
$1.13 billion of senior notes, borrowed and repaid $4.23 billion under its revolving credit facility, 
borrowed  and  repaid  $3.55  billion  under  its  trade  receivables  facility  and  had  net  borrowings  of 
$1.02  billion  under  its  commercial  paper  program.  MPLX  issued  $3.0  billion  of  senior  notes, 
which were used to repay $1.0 billion of outstanding borrowings under its term loan, $1.0 billion 
of  floating  rate  senior  notes  and  to  redeem  $750  million  of  fixed  rate  senior  notes,  and  had  net 
borrowings  of  $175  million  under  its  revolving  credit  facility.  During  2019,  MPLX  issued  $2 
billion of floating rate notes, the proceeds of which were used to repay various outstanding MPLX 
borrowings and for general business purposes, and had net borrowings of $1 billion under its term 
loan  agreement.  In  addition,  MPLX  repaid  $500  million  of  senior  notes.  During  2018,  MPLX 
issued $7.75 billion of senior notes, redeemed $750 million of senior notes, borrowed and repaid 
$4.1 billion under a term loan agreement, and borrowed and repaid $1.41 billion and $1.92 billion,

respectively,  under  the  MPLX  Credit  Agreement.  In  addition,  MPC  redeemed  $600  million  of 
senior notes. See Item 8. Financial Statements and Supplementary Data – Note 22 for additional 
information on our long-term debt.

Cash used in common stock repurchases totaled $1.95 billion in 2019 and $3.29 billion in 2018. 
See the “Capital Requirements” section for further discussion of our stock repurchases.

Cash  used  in  dividend  payments  totaled  $1.51  billion  in  2020,  $1.40  billion  in  2019  and  $954 
million in 2018. The increase in 2020 is primarily due to an increase in our base dividend, partially 
offset by a reduction of shares resulting from share repurchases in 2019. The increase in 2019 was 
primarily  due  a  net  increase  in  the  number  of  shares  outstanding  due  to  the  approximate  239.8 
million shares issued in connection with the Andeavor acquisition and a $0.28 per share increase 
in  our  base  dividend,  partially  offset  by  a  reduction  of  shares  resulting  from  share  repurchases. 
Dividends per share were $2.32 in 2020, $2.12 in 2019 and $1.84 in 2018.

Distributions  to  noncontrolling  interests  increased  $342  million  in  2019  compared  to  2018, 
primarily due to increases in MPLX units outstanding and MPLX’s distribution per common unit. 
Distributions  to  noncontrolling  interests  included  ANDX’s  distribution  per  common  unit  paid  in 
the  first  and  second  quarter  of  2019,  prior  to  the  merger  of  ANDX  and  MPLX,  and  the  fourth 
quarter of 2018 subsequent to the acquisition of Andeavor on October 1, 2018.

Capital Resources

MPC, Excluding MPLX

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

Our liquidity, excluding MPLX, totaled $7.3 billion at December 31, 2020 consisting of:

Outstanding  borrowings  include  $1  million  in  letters  of  credit  outstanding  under  this  facility.  Excludes  MPLX’s  $3.5  billion 
bank  revolving  credit  facility,  which  had $175  million  borrowings  and  no  of  letters  of  credit  outstanding  as  of December  31, 
2020.

In February 2021, we elected to cancel one of the $1.0 B 364-day revolving credit agreements prior to its maturity in April 2021.

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

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

facilities.

(e)

Includes  cash  and  cash  equivalents  classified  as  assets  held  for  sale  of  $140  million  (see  Item  8.  Financial  Statements  and 
Supplementary Data – Note 5) and excludes $15 million of MPLX cash and cash equivalents. 

Because of the alternatives available to us, including internally generated cash flow and access to capital 
markets, including a commercial paper program, we believe that our short-term and long-term liquidity is 
adequate  to  fund  not  only  our  current  operations,  but  also  our  near-term  and  long-term  funding 
requirements, including capital spending programs, dividend payments, defined benefit plan contributions,

repayment  of  debt  maturities  and  other  amounts  that  may  ultimately  be  paid  in  connection  with 
contingencies. During the year ended December 31, 2020, share repurchases were temporarily suspended, 
which has helped preserve our liquidity during the COVID-19 pandemic. The timing and amount of future 
repurchases  will  depend  upon  several  factors,  including  market  and  business  conditions,  and  such 
repurchases may be initiated, suspended or discontinued at any time.

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

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

We established a commercial paper program that allows us to have a maximum of $2 billion in commercial 
paper  outstanding,  with  maturities  up  to  397  days  from  the  date  of  issuance.  We  do  not  intend  to  have 
outstanding commercial paper borrowings in excess of available capacity under our bank revolving credit 
facilities. At December 31, 2020, we had $1.02 billion outstanding under the commercial paper program, 
which matures on various dates in the first quarter of 2021.

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

On April 27, 2020, MPC entered into a 364-day revolving credit agreement that provided for a $1.0 billion 
unsecured  revolving  credit  facility  that  was  scheduled  to  mature  in  April  2021.  In  February  2021,  we 
elected  to  terminate  this  credit  agreement.  This  facility  provided  MPC  additional  liquidity  and  financial 
flexibility  during  the  then  ongoing  commodity  price  and  demand  downturn.  We  no  longer  believe  the 
facility  is  necessary  as  an  additional  source  for  liquidity,  and  we  do  not  intend  to  replace  it.  No  early 
termination fees were incurred by MPC in connection with the termination of this credit agreement.	

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

The  MPC  credit  agreements  and  our  trade  receivables  facility  contain  representations  and  warranties, 
affirmative  and  negative  covenants  and  events  of  default  that  we  consider  usual  and  customary  for 
agreements of these types. The financial covenant 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. Other covenants restrict us and/or certain of our subsidiaries from incurring 
debt, creating liens on assets and entering into transactions with affiliates. As of December 31, 2020, we 
were in compliance with the covenants contained in the MPC credit agreements and our trade receivables 
facility, including the financial covenant with a ratio of Consolidated Net Debt to Total Capitalization of 
0.37 to 1.00.

Our intention is to maintain an investment-grade credit profile. As of February 1, 2021, the credit ratings on 
our senior unsecured debt are as follows.

Company

MPC

Rating Agency

Rating

Moody’s

Baa2 (negative outlook)

Standard & Poor’s

BBB (negative outlook)

Fitch

BBB (negative outlook)

The  ratings  reflect  the  respective  views  of  the  rating  agencies.  Although  it  is  our  intention  to  maintain  a 
credit profile that supports an investment-grade rating, there is no assurance that these ratings will continue 

72

 
for any given period of time. The ratings may be revised or withdrawn entirely by the rating agencies if, in 
their respective judgments, circumstances so warrant.

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

See Item 8. Financial Statements and Supplementary Data – Note 22 for further discussion of our debt.

On  August  18,  2020,  MPLX  issued  $3.0  billion  aggregate  principal  amount  of  senior  notes  in  a  public 
offering, consisting of $1.5 billion aggregate principal amount of 1.750% senior notes due March 2026 and 
$1.5 billion aggregate principal amount of 2.650% senior notes due August 2030. The net proceeds were 
used to repay $1.0 billion of outstanding borrowings under the MPLX term loan agreement, to repay the 
$1.0  billion  floating  rate  senior  notes  due  September  2021,  to  redeem  all  of  the  $300  million  aggregate 
principal  amount  of  MPLX’s  6.250%  senior  notes  due  October  2022  and  to  redeem  the  $450  million 
aggregate  principal  amount  of  6.375%  senior  notes  due  May  2024,  including  the  portion  of  such  notes 
issued by ANDX. The remaining proceeds were used for general business purposes. 

The  MPLX  credit  agreement  contains  certain  representations  and  warranties,  affirmative  and  restrictive 
covenants and events of default that we consider to be usual and customary for an agreement of this type. 
The financial covenant requires MPLX to maintain a ratio of Consolidated Total Debt as of the end of each 
fiscal quarter to Consolidated EBITDA (both as defined in the MPLX credit agreement) for the prior four 
fiscal  quarters  of  no  greater  than  5.0  to  1.0  (or  5.5  to  1.0  for  up  to  two  fiscal  quarters  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 
December 31, 2020, MPLX was in compliance with the covenants, including the financial covenant with a 
ratio of Consolidated Total Debt to Consolidated EBITDA of 3.8 to 1.0.

Our  intention  is  to  maintain  an  investment-grade  credit  profile  for  MPLX.  As  of  February  1,  2021,  the 
credit ratings on MPLX’s senior unsecured debt are as follows.

will continue for any given period of time. The ratings may be revised or withdrawn entirely by the rating

Neither the MPLX credit agreement or term loan agreement contains credit rating triggers that would result

Capital Requirements

Capital Spending

MPC’s  capital  investment  plan  for  2021  totals  approximately  $1.4  billion  for  capital  projects  and 
investments,  excluding  capitalized  interest,  potential  acquisitions  and  MPLX’s  capital  investment  plan. 
MPC’s 2021 capital investment plan includes all of the planned capital spending for Refining & Marketing, 
and Corporate as well as a portion of the planned capital investments in Midstream and Speedway’s capital 
spending for the first quarter which is now reported separately as discontinued operations. The remainder of 
the  planned  capital  spending  for  Midstream  reflects  the  capital  investment  plan  for  MPLX.  We 
continuously  evaluate  our  capital  plan  and  make  changes  as  conditions  warrant.  The  2021  capital 
investment  plan  for  MPC  and  MPLX  and  capital  expenditures  and  investments  for  each  of  the  last  three 
years are summarized by segment below.

Excludes  capitalized  interest  of $106  million,  $137  million  and  $80  million  for  2020,  2019  and  2018,  respectively.  The  2021 
capital investment plan excludes capitalized interest.

The MPLX capital investment plan excludes project reimbursements paid by MPC to MPLX and return of capital from MPLX’s 
joint venture partners.

Refining & Marketing 
The Refining & Marketing segment’s forecasted 2021 capital spending and investments is approximately 
$1.05  billion.  This  amount  includes  approximately  $800  million  of  growth  capital  focused  on  on-going 
projects, such as the first phase of the Martinez facility conversion, the STAR project, and projects that we 
expect will help us reduce future operating costs. Maintenance capital is expected to be $250 million.

Major  capital  projects  completed  over  the  last  three  years  have  prepared  us  to  increase  our  diesel 
production,  process  light  crude  oil,  increase  our  export  capabilities  and  meet  the  transportation  fuel 
regulatory mandate (Tier 3 fuel standards). In addition, the STAR investment project at our Galveston Bay 
refinery is progressing according to plan and is scheduled to complete in 2022.

Midstream 
MPLX’s capital investment plan includes $800 million of organic growth capital and approximately $200 
million  of  maintenance  capital.  This  growth  plan  is  focused  on  investments  in  projects  that  deliver  the 
highest  returns  as  we  continue  to  optimize  our  assets.  These  investments  are  focused  on  crude  oil  and 
natural gas logistics systems to transport products from the Permian to the U.S. Gulf Coast and increase our 

74

 
 
 
 
 
 
 
 
export capabilities. This provides for additional flexibility and competitive advantages in how we operate 
our  assets  as  these  projects  further  enhance  our  full  value  chain  capture.  Other  investments  include  the 
addition  of  approximately  400  MMcf/d  of  processing  capacity  at  two  gas  processing  plants,  one  in  the 
Marcellus  region  which  is  expected  to  be  completed  in  2021,  and  one  in  the  Southwest  region,  which  is 
expected to be completed in 2022. 

Major capital projects over the last three years included investments for the development of natural gas and 
natural gas liquids infrastructure to support MPLX’s producer customers, primarily in the Marcellus, Utica 
and  Permian  regions  and  development  of  various  crude  oil  and  refined  petroleum  products  infrastructure 
projects.

The  remaining  Midstream  segment’s  forecasted  2021  capital  spend,  excluding  MPLX,  is  approximately 
$50 million which primarily relates to investments in equity affiliates.

Corporate and Other
The  2021  capital  forecast  includes  approximately  $150  million  to  support  corporate  activities.  Major 
projects over the last three years included upgrades to information technology systems. 

Speedway
Speedway’s  2021  capital  forecast  for  the  first  quarter  of  approximately  $150  million  is  focused  on  new 
store growth in existing and new markets, commercial fueling/diesel expansion, food service through store 
remodels and equipment replacement/store maintenance.

Major  capital  projects  over  the  last  three  years  included  converting  recently  acquired  locations  to  the 
Speedway brand and systems, building new store locations, remodeling and rebuilding existing locations in 
core  markets  and  building  out  our  network  of  commercial  fueling  lane  locations  to  capitalize  on  diesel 
demand growth. 

Dividends

On January 29, 2021, we announced our board of directors approved a $0.58 per share dividend, payable 
March 10, 2021 to shareholders of record at the close of business on February 17, 2021.

Share Repurchases

During  the  year  ended  December  31,  2020,  share  repurchases  were  temporarily  suspended,  which  has 
helped  preserve  our  liquidity  during  the  COVID-19  pandemic.  The  timing  and  amount  of  future 
repurchases  will  depend  upon  several  factors,  including  market  and  business  conditions,  and  such 
repurchases may be initiated, suspended or discontinued at any time. Since January 1, 2012, our board of 
directors  has  approved  $18.0  billion  in  total  share  repurchase  authorizations  and  we  have  repurchased  a 
total of $15.0 billion of our common stock, leaving approximately $3.0 billion available for repurchases as 
of December 31, 2020. Under these authorizations, we have acquired 327 million shares at an average cost 
per  share  of  $46.05.  The  table  below  summarizes  our  total  share  repurchases.  See  Item  8.  Financial 
Statements and Supplementary Data – Note 12 for further discussion of the share repurchase plans.

We may utilize various methods to effect the repurchases, which could include open market repurchases, 
negotiated block transactions, tender offers, accelerated share repurchases or open market solicitations for 
shares, some of which may be effected through Rule 10b5-1 plans. 

MPLX Unit Repurchases

On  November  2,  2020,  MPLX  announced  the  board  authorization  of  a  unit  repurchase  program  for  the 
repurchase of up to $1 billion of MPLX’s outstanding common units held by the public. MPLX may utilize 
various methods to effect the repurchases, which could include open market repurchases, negotiated block 
transactions,  tender  offers,  accelerated  unit  repurchases  or  open  market  solicitations  for  units,  some  of 
which may be effected through Rule 10b5-1 plans. The timing and amount of repurchases will depend upon 

75

 
 
 
several factors, including market and business conditions, and repurchases may be initiated, suspended or 
discontinued at any time. The repurchase authorization has no expiration date.

During  the  year  ended  December  31,  2020,  1,473,843  MPLX  common  units  had  been  repurchased  at  an 
average cost per unit of $22.29. Total cash paid for units repurchased during the year was $33 million and 
$967 million remained outstanding on the program for future repurchases as of December 31, 2020. As of 
December  31,  2020,  MPLX  had  agreements  to  acquire  99,406  additional  common  units  for  $2  million, 
which settled in early January 2021.

Other Capital Requirements

In  2020,  we  made  contributions  totaling  $3  million  to  our  funded  pension  plans.  For  2021,  we  have  $65 
million of required funding and we may make voluntary contributions to our funded pension plans at our 
discretion.

We have $1.0 billion of 5.125 percent senior notes due in March 2021 that will be paid utilizing existing 
resources.

As of December 31, 2020, $141 million of restructuring expenses were accrued as restructuring reserves in 
our  consolidated  balance  sheet  and  we  expect  cash  payments  for  the  majority  of  these  reserves  to  occur 
within the next nine months.

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

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 accounting principles generally accepted in the United States. 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 Item 8. Financial Statements and Supplementary Data – Note 29.

TRANSACTIONS WITH RELATED PARTIES

We  believe  that  transactions  with  related  parties  were  conducted  on  terms  comparable  to  those  with 
unaffiliated parties. See Item 8. Financial Statements and Supplementary Data – Note 10 for discussion of 
activity with related parties.

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.

Legislation and regulations pertaining to fuel specifications, climate change and greenhouse gas emissions 
have the potential to materially adversely impact our business, financial condition, results of operations and 
cash flows, including costs of compliance and permitting delays. The extent and magnitude of these adverse 
impacts cannot be reliably or accurately estimated at this time because specific regulatory and legislative 
requirements have not been finalized and uncertainty exists with respect to the measures being considered, 
the costs and the time frames for compliance, and our ability to pass compliance costs on to our customers.

Our  environmental  expenditures,  including  non-regulatory  expenditures,  for  each  of  the  last  three  years 
were:

Based on the American Petroleum Institute’s definition of environmental expenditures.

These  amounts  include  spending  charged  against  remediation  reserves,  where  permissible,  but  exclude  non-cash  provisions 
recorded for environmental remediation.

We accrue for environmental remediation activities when the responsibility to remediate is probable and the 
amount  of  associated  costs  can  be  reasonably  estimated.  As  environmental  remediation  matters  proceed 
toward  ultimate  resolution  or  as  additional  remediation  obligations  arise,  charges  in  excess  of  those 
previously accrued may be required.

New or expanded environmental requirements, which could increase our environmental costs, may arise in 
the future. It is not possible to predict all of the ultimate costs of compliance, including remediation costs 
that may be incurred and penalties that may be imposed.

Our  environmental  capital  expenditures  accounted  for  6  percent,  12  percent  and  11  percent  of  capital 
expenditures,  for  2020,  2019  and  2018,  respectively,  excluding  acquisitions.  Our  environmental  capital 
expenditures are expected to approximate $39 million, or 2 percent, of total planned capital expenditures in 
2021.  Actual  expenditures  may  vary  as  the  number  and  scope  of  environmental  projects  are  revised  as  a 
result  of  improved  technology  or  changes  in  regulatory  requirements  and  could  increase  if  additional 
projects are identified or additional requirements are imposed. 

For more information on environmental regulations that impact us, or could impact us, see Item 1. Business 
– Regulatory Matters and Item 1A. Risk Factors.

CRITICAL ACCOUNTING ESTIMATES

The  preparation  of  financial  statements  in  accordance  with  GAAP  requires  us  to  make  estimates  and 
assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets 
and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues 
and expenses during the respective reporting periods. Accounting estimates are considered to be critical if 
(1) the nature of the estimates and assumptions is material due to the levels of subjectivity and judgment 
necessary to account for highly uncertain matters or the susceptibility of such matters to change; and (2) the 
impact of the estimates and assumptions on financial condition or operating performance is material. Actual 
results could differ from the estimates and assumptions used.

Fair Value Estimates

Fair  value  is  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly 
transaction between market participants at the measurement date. There are three approaches for measuring 
the  fair  value  of  assets  and  liabilities:  the  market  approach,  the  income  approach  and  the  cost  approach, 
each of which includes multiple valuation techniques. The market approach uses prices and other relevant 
information  generated  by  market  transactions  involving  identical  or  comparable  assets  or  liabilities.  The 
income  approach  uses  valuation  techniques  to  measure  fair  value  by  converting  future  amounts,  such  as 
cash flows or earnings, into a single present value amount using current market expectations about those 
future amounts. The cost approach is based on the amount that would currently be required to replace the 
service  capacity  of  an  asset.  This  is  often  referred  to  as  current  replacement  cost.  The  cost  approach 
assumes that the fair value would not exceed what it would cost a market participant to acquire or construct 
a substitute asset of comparable utility, adjusted for obsolescence.

The  fair  value  accounting  standards  do  not  prescribe  which  valuation  technique  should  be  used  when 
measuring fair value and does not prioritize among the techniques. These standards establish a fair value 
hierarchy that prioritizes the inputs used in applying the various valuation techniques. Inputs broadly refer 
to the assumptions that market participants use to make pricing decisions, including assumptions about risk. 
Level 1 inputs are given the highest priority in the fair value hierarchy while Level 3 inputs are given the 
lowest priority. The three levels of the fair value hierarchy are as follows:

•

•

•

Level 1 – Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities 
in active markets as of the measurement date. Active markets are those in which transactions for 
the asset or liability occur in sufficient frequency and volume to provide pricing information on an 
ongoing basis.

Level 2 – Observable market-based inputs or unobservable inputs that are corroborated by market 
data. These are inputs other than quoted prices in active markets included in Level 1, which are 
either directly or indirectly observable as of the measurement date.

Level  3  –  Unobservable  inputs  that  are  not  corroborated  by  market  data  and  may  be  used  with 
internally developed methodologies that result in management’s best estimate of fair value.

Valuation  techniques  that  maximize  the  use  of  observable  inputs  are  favored.  Assets  and  liabilities  are 
classified  in  their  entirety  based  on  the  lowest  priority  level  of  input  that  is  significant  to  the  fair  value 
measurement.  The  assessment  of  the  significance  of  a  particular  input  to  the  fair  value  measurement 
requires judgment and may affect the placement of assets and liabilities within the levels of the fair value 
hierarchy. We use an income or market approach for recurring fair value measurements and endeavor to use 
the  best  information  available.  See  Item  8.  Financial  Statements  and  Supplementary  Data  –  Note  20  for 
disclosures regarding our fair value measurements.

Significant uses of fair value measurements include:

•

•

•
•
•
•

assessment of impairment of long-lived assets;

assessment of impairment of intangible assets:

assessment of impairment of goodwill;
assessment of impairment of equity method investments;
recorded values for assets acquired and liabilities assumed in connection with acquisitions; and
recorded values of derivative instruments.

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

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

•

•

•

•

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

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

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

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

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

The  need  to  test  for  impairment  can  be  based  on  several  indicators,  including  a  significant  reduction  in 
prices of or demand for products produced, a weakened outlook for profitability, a significant reduction in 
pipeline  throughput  volumes,  a  significant  reduction  in  natural  gas  or  natural  gas  liquids  processed,  a 
significant  reduction  in  refining  margins,  other  changes  to  contracts  or  changes  in  the  regulatory 
environment.  The  following  sections  detail  our  critical  accounting  estimates  related  to  impairment 
assessments for long-lived assets, goodwill and equity method investments.

Long-lived Asset Impairment Assessments

Long-lived  assets  used  in  operations  are  assessed  for  impairment  whenever  changes  in  facts  and 
circumstances indicate that the carrying value of the assets may not be recoverable based on the expected 
undiscounted future cash flow of an asset group. For purposes of impairment evaluation, long-lived assets 
must be grouped at the lowest level for which independent cash flows can be identified, which generally is 
the refinery and associated distribution system level for Refining & Marketing segment assets, and the plant 
level  or  pipeline  system  level  for  Midstream  segment  assets.  If  the  sum  of  the  undiscounted  estimated 
pretax cash flows is less than the carrying value of an asset group, fair value is calculated, and the carrying 
value  is  written  down  to  the  calculated  fair  value.  The  Company’s  consolidated  long-lived  asset  balance 
was $43 billion as of December 31, 2020.

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

80

During the second quarter of 2020, we identified long-lived asset impairment triggers relating to all of our 
refinery asset groups within the Refining & Marketing segment, except the Gallup refinery which had been 
impaired in the first quarter, as a result of continued macroeconomic developments impacting the Refining 
& Marketing segment expected future cash flows. All of these refinery asset groups undiscounted estimated 
pretax cash flows exceeded the carrying value by at least 17 percent.

On  August  3,  2020,  we  announced  our  plans  to  evaluate  possibilities  to  strategically  reposition  our 
Martinez  refinery,  including  the  potential  conversion  of  the  refinery  into  a  renewable  diesel  facility. 
Subsequent  to  August  3,  2020,  we  progressed  activities  associated  with  the  conversion  of  the  Martinez 
refinery to a renewable diesel facility, including applying for permits, advancing discussions with feedstock 
suppliers,  and  beginning  detailed  engineering  activities.  As  envisioned,  the  Martinez  facility  would  start 
producing approximately 260 million gallons per year of renewable diesel by the second half of 2022, with 
a potential to build to full capacity of approximately 730 million gallons per year by the end of 2023. As a 
result of the progression of these activities, we identified assets that would be repurposed and utilized in a 
renewable diesel facility configuration and assets that would be abandoned since they had no function in a 
renewable diesel facility configuration. This change in our intended use for the Martinez refinery is a long-
lived asset impairment trigger for the assets that would be repurposed and remain as part of the Martinez 
asset group. We assessed the asset group for impairment by comparing the undiscounted estimated pretax 
cash  flows  to  the  carrying  value  of  the  asset  group  and  the  undiscounted  estimated  pretax  cash  flows 
exceeded the Martinez asset group carrying value. We recorded impairment expense of $342 million for the 
abandoned assets as we are no longer using these assets and have no expectation to use these assets in the 
future.  Additionally,  as  a  result  of  our  efforts  to  progress  the  conversion  of  Martinez  refinery  into  a 
renewable  diesel  facility,  MPLX  cancelled  in-process  capital  projects  related  to  its  Martinez  refinery 
logistics operations resulting in impairments of $27 million in the third quarter.

In the fourth quarter of 2020, we concluded the evaluation of our intended use of MPLX terminal assets 
near the Gallup refinery and determined that the assets were abandoned, resulting in an impairment charge 
of  $67  million.  Following  this  conclusion,  we  revised  the  estimate  of  the  salvage  value  for  the  Gallup 
refinery asset group resulting in an additional $44 million impairment charge. These charges are included in 
impairment expense on our consolidated statements of income.

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

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

81

impairment analysis will prove to be an accurate prediction of the future. The fair value measurements for 
the asset group fair values represent Level 3 measurements.

Goodwill Impairment Assessments

Unlike long-lived assets, goodwill is subject to annual, or more frequent if necessary, impairment testing at 
the reporting unit level. A goodwill impairment loss is measured as the amount by which a reporting unit's 
carrying  value  exceeds  its  fair  value,  without  exceeding  the  recorded  amount  of  goodwill.  As  of 
December 31, 2020, we had a total of $8.26 billion of goodwill recorded on our consolidated balance sheet, 
which  was  associated  with  four  of  our  eight  reporting  units.  An  additional  reporting  unit,  Speedway,  has 
goodwill of $4.4 billion and is reported within assets held for sale on our consolidated balance sheets.

The outbreak of COVID-19, its development into a pandemic and the decline in commodity prices during 
the first quarter of 2020 had significant effects on our business. See “Business Update” in Item 1. Business 
above. Due to these developments, we performed impairment assessments during the first quarter of 2020 
as discussed further below.

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

Prior  to  performing  our  annual  impairment  assessment  as  of  November  30,  2020,  MPC  had  goodwill 
totaling  approximately  $8.26  billion  associated  with  four  reporting  units.  Additionally,  a  fifth  reporting 
unit, Speedway, is reported in assets held for sale in our consolidated balance sheets and has $4.4 billion of 
goodwill. Management performed a qualitative assessment for three reporting units as we determined it was 
more likely than not that the fair values of the reporting units exceeded the carrying values. A quantitative 
assessment was last performed on these reporting units either on November 30, 2019 or March 31, 2020 
and these reporting units’ fair values exceeded carrying values by a range of approximately 90 percent to 
270 percent. A quantitative assessment was performed for the remaining two reporting units which resulted 
in  the  fair  value  of  the  reporting  units  exceeding  their  carrying  value  by  percentages  ranging  from 
approximately 9 percent to 42 percent. The reporting unit whose fair value exceeded its carrying amount by 
9 percent, our Crude Gathering Reporting unit, had goodwill totaling $1.1 billion at December 31, 2020. 
The  excess  fair  value  over  carrying  value  for  this  reporting  unit  is  consistent  with  prior  assessments.  An 
increase of one percentage point to the discount rate used to estimate the fair value of this reporting unit 
would not have resulted in goodwill impairment as of November 30, 2020.

Significant  assumptions  used  to  estimate  the  reporting  units’  fair  value  included  estimates  of  future  cash 
flows and market information for comparable assets. If estimates for future cash flows, which are impacted 
by future margins on products produced or sold, future volumes, and capital requirements, were to decline, 
the overall reporting units’ fair values would decrease, resulting in potential goodwill impairment charges. 
Fair  value  determinations  require  considerable  judgment  and  are  sensitive  to  changes  in  underlying 

82

assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for 
purposes of the impairment tests will prove to be an accurate prediction of the future.

Equity Method Investment Impairment Assessment

Equity method investments are assessed for impairment whenever factors indicate an other than temporary 
loss in value. Factors providing evidence of such a loss include the fair value of an investment that is less 
than  its  carrying  value,  absence  of  an  ability  to  recover  the  carrying  value  or  the  investee’s  inability  to 
generate income sufficient to justify our carrying value. During the first quarter of 2020, we recorded $1.32 
billion of equity method investment impairment charges to income from equity method investments in the 
consolidated statements of income. The impairment charges primarily related to MPLX recording an other 
than temporary impairment totaling $1.26 billion, of which $1.25 billion related to MarkWest Utica EMG, 
L.L.C  and  its  investment  in  Ohio  Gathering  Company,  L.L.C.  The  fair  value  of  the  investments  was 
determined  based  upon  applying  the  discounted  cash  flow  method,  which  is  an  income  approach.  The 
discounted  cash  flow  fair  value  estimate  is  based  on  known  or  knowable  information  at  the  interim 
measurement  date.  The  significant  assumptions  that  were  used  to  develop  the  estimate  of  the  fair  value 
under  the  discounted  cash  flow  method  include  management’s  best  estimates  of  the  expected  future  cash 
flows, including prices and volumes, the weighted average cost of capital and the long-term growth rate. 
Fair  value  determinations  require  considerable  judgment  and  are  sensitive  to  changes  in  underlying 
assumptions and factors. As such, the fair value of these equity method investments represents a Level 3 
measurement. As a result, there can be no assurance that the estimates and assumptions made for purposes 
of the impairment test will prove to be an accurate prediction of the future. The impairment was recorded 
through  “Income  from  equity  method  investments.”  The  impairments  were  largely  due  to  a  reduction  in 
forecasted volumes gathered and processed by the systems operated by the joint ventures. At December 31, 
2020,  we  had  $5.42  billion  of  investments  in  equity  method  investments  recorded  on  our  consolidated 
balance sheet. 

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

See  Item  8.  Financial  Statements  and  Supplementary  Data  –  Note  17  for  additional  information  on  our 
equity  method  investments.  See  Item  8.  Financial  Statements  and  Supplementary  Data  –  Note  19  for 
additional  information  on  our  goodwill  and  intangibles,  including  a  table  summarizing  our  recorded 
goodwill by segment. 

Acquisitions

In accounting for business combinations, acquired assets, assumed liabilities and contingent consideration 
are  recorded  based  on  estimated  fair  values  as  of  the  date  of  acquisition.  The  excess  or  shortfall  of  the 
purchase  price  when  compared  to  the  fair  value  of  the  net  tangible  and  identifiable  intangible  assets 
acquired, if any, is recorded as goodwill or a bargain purchase gain, respectively. A significant amount of 
judgment is involved in estimating the individual fair values of property, plant and equipment, intangible 
assets, contingent consideration and other assets and liabilities. We use all available information to make 
these  fair  value  determinations  and,  for  certain  acquisitions,  engage  third-party  consultants  for  valuation 
assistance.

The  fair  value  of  assets  and  liabilities,  including  contingent  consideration,  as  of  the  acquisition  date  are 
often  estimated  using  a  combination  of  approaches,  including  the  income  approach,  which  requires  us  to 
project  future  cash  flows  and  apply  an  appropriate  discount  rate;  the  cost  approach,  which  requires 
estimates  of  replacement  costs  and  depreciation  and  obsolescence  estimates;  and  the  market  approach 
which uses market data and adjusts for entity-specific differences. The estimates used in determining fair 
values are based on assumptions believed to be reasonable but which are inherently uncertain. Accordingly, 
actual results may differ materially from the projected results used to determine fair value. 

See  Item  8.  Financial  Statements  and  Supplementary  Data  –  Note  8  for  additional  information  on  our 
acquisitions.  See  Item  8.  Financial  Statements  and  Supplementary  Data  –  Note  20  for  additional 
information on fair value measurements.

83

Derivatives

We  record  all  derivative  instruments  at  fair  value.  Substantially  all  of  our  commodity  derivatives  are 
cleared  through  exchanges  which  provide  active  trading  information  for  identical  derivatives  and  do  not 
require any assumptions in arriving at fair value. Fair value estimation for all our derivative instruments is 
discussed in Item 8. Financial Statements and Supplementary Data – Note 20. Additional information about 
derivatives  and  their  valuation  may  be  found  in  Item  7A.  Quantitative  and  Qualitative  Disclosures  about 
Market Risk.

Variable Interest Entities

We evaluate all legal entities in which we hold an ownership or other pecuniary interest to determine if the 
entity  is  a  VIE.  Our  interests  in  a  VIE  are  referred  to  as  variable  interests.  Variable  interests  can  be 
contractual, ownership or other pecuniary interests in an entity that change with changes in the fair value of 
the  VIE’s  assets.  When  we  conclude  that  we  hold  an  interest  in  a  VIE  we  must  determine  if  we  are  the 
entity’s primary beneficiary. A primary beneficiary is deemed to have a controlling financial interest in a 
VIE. This controlling financial interest is evidenced by both (a) the power to direct the activities of the VIE 
that most significantly impact the VIE’s economic performance and (b) the obligation to absorb losses that 
could  potentially  be  significant  to  the  VIE  or  the  right  to  receive  benefits  that  could  potentially  be 
significant to the VIE. We consolidate any VIE when we determine that we are the primary beneficiary. We 
must disclose the nature of any interests in a VIE that is not consolidated. 

Significant judgment is exercised in determining that a legal entity is a VIE and in evaluating our interest in 
a VIE. We use primarily a qualitative analysis to determine if an entity is a VIE. We evaluate the entity’s 
need for continuing financial support; the equity holder’s lack of a controlling financial interest; and/or if 
an equity holder’s voting interests are disproportionate to its obligation to absorb expected losses or receive 
residual returns. We evaluate our interests in a VIE to determine whether we are the primary beneficiary. 
We  use  a  primarily  qualitative  analysis  to  determine  if  we  are  deemed  to  have  a  controlling  financial 
interest in the VIE, either on a standalone basis or as part of a related party group. We continually monitor 
our interests in legal entities for changes in the design or activities of an entity and changes in our interests, 
including our status as the primary beneficiary to determine if the changes require us to revise our previous 
conclusions. 

Changes in the design or nature of the activities of a VIE, or our involvement with a VIE, may require us to 
reconsider our conclusions on the entity’s status as a VIE and/or our status as the primary beneficiary. Such 
reconsideration  requires  significant  judgment  and  understanding  of  the  organization.  This  could  result  in 
the deconsolidation or consolidation of the affected subsidiary, which would have a significant impact on 
our financial statements. 

Variable Interest Entities are discussed in Item 8. Financial Statements and Supplementary Data – Note 9.

Pension and Other Postretirement Benefit Obligations

Accounting  for  pension  and  other  postretirement  benefit  obligations  involves  numerous  assumptions,  the 
most significant of which relate to the following:

•

•

•

•

•

the discount rate for measuring the present value of future plan obligations;

the expected long-term return on plan assets;

the rate of future increases in compensation levels; 

health care cost projections; and

the mortality table used in determining future plan obligations.

We  utilize  the  work  of  third-party  actuaries  to  assist  in  the  measurement  of  these  obligations.  We  have 
selected different discount rates for each of our pension plans and retiree health and welfare based on the 
projected  benefit  payment  patterns  of  each  individual  plan.  The  selected  rates  are  compared  to  various 
similar bond indices for reasonableness. In determining the assumed discount rates, we use our third-party 
actuaries’ discount rate models. These models calculate an equivalent single discount rate for the projected 
benefit  plan  cash  flows  using  yield  curves  derived  from  Aa  or  higher  corporate  bond  yields.  The  yield 
curves represent a series of annualized individual spot discount rates from 0.5 to 99 years. The bonds used 
have an average rating of Aa or higher by a recognized rating agency and generally only non-callable bonds 
are included. Outlier bonds that have a yield to maturity that deviate significantly from the average yield 
within  each  maturity  grouping  are  not  included.  Each  issue  is  required  to  have  at  least  $250  million  par 
value outstanding.

84

Of the assumptions used to measure the year-end obligations and estimated annual net periodic benefit cost, 
the  discount  rate  has  the  most  significant  effect  on  the  periodic  benefit  cost  reported  for  the  plans. 
Decreasing  the  discount  rates  of  2.55  percent  for  our  pension  plans  and  2.60  percent  for  our  other 
postretirement  benefit  plans  by  0.25  percent  would  increase  pension  obligations  and  other  postretirement 
benefit plan obligations by $110 million and $42 million, respectively, and would increase defined benefit 
pension expense and other postretirement benefit plan expense by $15 million and $3 million, respectively.

The  long-term  asset  rate  of  return  assumption  considers  the  asset  mix  of  the  plans  (currently  targeted  at 
approximately 50 percent equity securities and 50 percent fixed income securities for the primary funded 
pension plan), past performance and other factors. Certain components of the asset mix are modeled with 
various  assumptions  regarding  inflation  and  returns.  In  addition,  our  long-term  asset  rate  of  return 
assumption is compared to those of other companies and to historical returns for reasonableness. We used 
the  6.00  percent  long-term  rate  of  return  to  determine  our  2020  defined  benefit  pension  expense.  After 
evaluating  activity  in  the  capital  markets,  along  with  the  current  and  projected  plan  investments,  we 
decreased the asset rate of return for our primary plan to 5.75 percent effective for 2021. Decreasing the 
5.75 percent asset rate of return assumption by 0.25 percentage points would increase our defined benefit 
pension expense by $5 million.

Compensation  change  assumptions  are  based  on  historical  experience,  anticipated  future  management 
actions and demographics of the benefit plans.

Health care cost trend assumptions are developed based on historical cost data, the near-term outlook and 
an assessment of likely long-term trends.

We utilized the 2020 mortality tables from the U.S. Society of Actuaries.

Item  8.  Financial  Statements  and  Supplementary  Data  –  Note  26  includes  detailed  information  about  the 
assumptions  used  to  calculate  the  components  of  our  annual  defined  benefit  pension  and  other 
postretirement plan expense, as well as the obligations and accumulated other comprehensive loss reported 
on the year-end balance sheets.

ACCOUNTING STANDARDS NOT YET ADOPTED

As discussed in Item 8. Financial Statements and Supplementary Data – Note 3 to our audited consolidated 
financial  statements,  certain  new  financial  accounting  pronouncements  will  be  effective  for  our  financial 
statements in the future.

ITEM  7A.  QUANTITATIVE  AND  QUALITATIVE  DISCLOSURES  ABOUT  MARKET 
RISK

General

We are exposed to market risks related to the volatility of crude oil and refined product prices. We employ 
various strategies, including the use of commodity derivative instruments, to hedge the risks related to these 
price  fluctuations.  We  are  also  exposed  to  market  risks  related  to  changes  in  interest  rates  and  foreign 
currency exchange rates. As of December 31, 2020, we did not have any financial derivative instruments to 
hedge  the  risks  related  to  interest  rate  fluctuations;  however,  we  have  used  them  in  the  past,  and  we 
continually monitor the market and our exposure and may enter into these agreements again in the future. 
We are at risk for changes in fair value of all of our derivative instruments; however, such risk should be 
mitigated by price or rate changes related to the underlying commodity or financial transaction.

We believe that our use of derivative instruments, along with our risk assessment procedures and internal 
controls,  does  not  expose  us  to  material  adverse  consequences.  While  the  use  of  derivative  instruments 
could materially affect our results of operations in particular quarterly or annual periods, we believe that the 
use of these instruments will not have a material adverse effect on our financial position or liquidity.

See Item 8. Financial Statements and Supplementary Data – Notes 20 and 21 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.

Commodity Price Risk

Refining & Marketing

Our strategy is to obtain competitive prices for our products and allow operating results to reflect market 
price movements dictated by supply and demand. We use a variety of commodity derivative instruments, 
including futures and options, as part of an overall program to hedge commodity price risk. We also do a 
limited amount of trading not directly related to our physical transactions. 

We use commodity derivative instruments on crude oil and refined product inventories to hedge price risk 
associated  with  inventories  above  or  below  LIFO  inventory  targets.  We  also  use  derivative  instruments 
related to the acquisition of foreign-sourced crude oil and ethanol blended with refined petroleum products 
to hedge price risk associated with market volatility between the time we purchase the product and when 
we use it in the refinery production process or it is blended. In addition, we may use commodity derivative 
instruments on fixed price contracts for the sale of refined products to hedge risk by converting the refined 
product sales to market-based prices. The majority of these derivatives are exchange-traded contracts but 
we also enter into over-the-counter swaps, options and over-the-counter options. We closely monitor and 
hedge our exposure to market risk on a daily basis in accordance with policies approved by our board of 
directors. Our positions are monitored daily by a risk control group to ensure compliance with our stated 
risk management policy.

Midstream

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  MPLX’s  control.  MPLX  may  at  times  use  a  variety  of  commodity 
derivative instruments, including futures and options, as part of an overall program to economically hedge 
commodity  price  risk.  A  portion  of  MPLX’s  profitability  is  directly  affected  by  prevailing  commodity 
prices primarily as a result of purchasing and selling NGLs and natural gas at index-related prices. To the 
extent that commodity prices influence the level of drilling by MPLX producer customers, such prices also 
indirectly affect profitability. MPLX may enter into derivative contracts, which are primarily swaps traded 
on  the  OTC  market  as  well  as  fixed  price  forward  contracts.  MPLX’s  risk  management  policy  does  not 
allow  it  to  enter  into  speculative  positions  with  its  derivative  contracts.  Execution  of  MPLX’s  hedge 
strategy and the continuous monitoring of commodity markets and its open derivative positions are carried 
out by its hedge committee, comprised of members of senior management.

To mitigate MPLX’s cash flow exposure to fluctuations in the price of NGLs, it may use NGL derivative 
swap contracts. A small portion of its NGL price exposure may be managed by using crude oil contracts. 
To mitigate MPLX’s cash flow exposure to fluctuations in the price of natural gas, it may use natural gas 

86

derivative swap contracts, taking into account the partial offset of its long and short natural gas positions 
resulting from normal operating activities.

MPLX  would  be  exposed  to  additional  commodity  risk  in  certain  situations  such  as  if  producers 
under‑deliver or over‑deliver products or if processing facilities are operated in different recovery modes. 
In  the  event  that  MPLX  has  derivative  positions  in  excess  of  the  product  delivered  or  expected  to  be 
delivered, the excess derivative positions may be terminated. 

MPLX management conducts a standard credit review on counterparties to derivative contracts, and it has 
provided the counterparties with a guaranty as credit support for its obligations. MPLX uses standardized 
agreements that allow for offset of certain positive and negative exposures in the event of default or other 
terminating events, including bankruptcy.

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 
December 31, 2020 would cause future IFO effects to differ from those presented above.

Interest Rate Risk

Our use of fixed or variable-rate debt directly exposes us to interest rate risk. Fixed rate debt, such as our 
senior  notes,  exposes  us  to  changes  in  the  fair  value  of  our  debt  due  to  changes  in  market  interest  rates. 
Fixed rate debt also exposes us to the risk that we may need to refinance maturing debt with new debt at 
higher rates or that our current fixed rate debt may be higher than the current market. Variable-rate debt, 
such as borrowings under our revolving credit facilities, exposes us to short-term changes in market rates 
that impact our interest expense. See Item 8. Financial Statements and Supplementary Data – Note 22 for 
additional information on our debt.

Foreign Currency Exchange Rate Risk 

We  are  impacted  by  foreign  exchange  rate  fluctuations  related  to  some  of  our  purchases  of  crude  oil 
denominated in Canadian dollars. We did not utilize derivatives to hedge our market risk exposure to these 
foreign exchange rate fluctuations in 2020. 

Counterparty Risk 

We are subject to risk of loss resulting from nonpayment by our customers to whom we provide services, 
lease  assets,  or  sell  natural  gas  or  NGLs.  We  believe  that  certain  contracts  would  allow  us  to  pass  those 
losses  through  to  our  customers,  thus  reducing  our  risk,  when  we  are  selling  NGLs  and  acting  as  our 
producer  customers’  agent.  Our  credit  exposure  related  to  these  customers  is  represented  by  the  value  of 
our trade receivables or lease receivables. Where exposed to credit risk, we analyze the customer’s financial 
condition  prior  to  entering  into  a  transaction  or  agreement,  establish  credit  terms  and  monitor  the 
appropriateness of these terms on an ongoing basis. In the event of a customer default, we may sustain a 
loss and our cash receipts could be negatively impacted.

We  are  subject  to  risk  of  loss  resulting  from  nonpayment  or  nonperformance  by  counterparties  to  our 
derivative contracts. Our credit exposure related to commodity derivative instruments is represented by the 
fair value of contracts with a net positive fair value at the reporting date. Outstanding instruments expose us 
to  credit  loss  in  the  event  of  nonperformance  by  the  counterparties  to  the  agreements.  Should  the 
creditworthiness of one or more of our counterparties decline, our ability to mitigate nonperformance risk is 
limited  to  a  counterparty  agreeing  to  either  a  voluntary  termination  and  subsequent  cash  settlement  or  a 
novation of the derivative contract to a third party. In the event of a counterparty default, we may sustain a 
loss and our cash receipts could be negatively impacted.

MANAGEMENT’S RESPONSIBILITIES FOR FINANCIAL STATEMENTS

The  accompanying  consolidated  financial  statements  of  Marathon  Petroleum  Corporation  and  its 
subsidiaries  (“MPC”)  are  the  responsibility  of  management  and  have  been  prepared  in  conformity  with 
accounting principles generally accepted in the United States of America. They necessarily include some 
amounts  that  are  based  on  best  judgments  and  estimates.  The  financial  information  displayed  in  other 
sections of this Annual Report on Form 10-K is consistent with these consolidated financial statements.

MPC  seeks  to  assure  the  objectivity  and  integrity  of  its  financial  records  by  careful  selection  of  its 
managers,  by  organizational  arrangements  that  provide  an  appropriate  division  of  responsibility  and  by 
communications  programs  aimed  at  assuring  that  its  policies  and  methods  are  understood  throughout  the 
organization.

The board of directors pursues its oversight role in the area of financial reporting and internal control over 
financial  reporting  through  its  Audit  Committee.  This  committee,  composed  solely  of  independent 
directors, regularly meets (jointly and separately) with the independent registered public accounting firm, 
management and internal auditors to monitor the proper discharge by each of their responsibilities relative 
to internal accounting controls and the consolidated financial statements.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

MPC’s management is responsible for establishing and maintaining adequate internal control over financial 
reporting  (as  defined  in  Rule  13a-15(f)  under  the  Securities  Exchange  Act  of  1934,  as  amended).  An 
evaluation  of  the  design  and  effectiveness  of  our  internal  control  over  financial  reporting,  based  on  the 
framework  in  Internal  Control  –  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring 
Organizations  of  the  Treadway  Commission,  was  conducted  under  the  supervision  and  with  the 
participation of management, including our chief executive officer and chief financial officer. Based on the 
results  of  this  evaluation,  MPC’s  management  concluded  that  its  internal  control  over  financial  reporting 
was effective as of December 31, 2020.

The  effectiveness  of  MPC’s  internal  control  over  financial  reporting  as  of  December  31,  2020  has  been 
audited  by  PricewaterhouseCoopers  LLP,  an  independent  registered  public  accounting  firm,  as  stated  in 
their report which is included herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Marathon Petroleum Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Marathon Petroleum Corporation and its 
subsidiaries (the “Company”) as of December 31, 2020 and 2019, and the related consolidated statements 
of income, of comprehensive income, of equity and redeemable noncontrolling interest and of cash flows 
for each of the three years in the period ended December 31, 2020, including the related notes (collectively 
referred to as the “consolidated financial statements”). We also have audited the Company's internal control 
over  financial  reporting  as  of  December  31,  2020,  based  on  criteria  established  in  Internal  Control  - 
Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission (COSO).

In  our  opinion,  the  consolidated  financial  statements  referred  to  above  present  fairly,  in  all  material 
respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its 
operations  and  its  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2020  in 
conformity  with  accounting  principles  generally  accepted  in  the  United  States  of  America.  Also  in  our 
opinion, the Company maintained, in all material respects, effective internal control over financial reporting 
as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) 
issued by the COSO.

Basis for Opinions

The  Company's  management  is  responsible  for  these  consolidated  financial  statements,  for  maintaining 
effective  internal  control  over  financial  reporting,  and  for  its  assessment  of  the  effectiveness  of  internal 
control over financial reporting, included in the accompanying Management’s Report on Internal Control 
Over  Financial  Reporting.  Our  responsibility  is  to  express  opinions  on  the  Company’s  consolidated 
financial statements and on the Company's internal control over financial reporting based on our audits. We 
are  a  public  accounting  firm  registered  with  the  Public  Company  Accounting  Oversight  Board  (United 
States) (PCAOB) and are required to be independent with respect to the Company in accordance with the 
U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the  Securities  and  Exchange 
Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we 
plan  and  perform  the  audits  to  obtain  reasonable  assurance  about  whether  the  consolidated  financial 
statements are free of material misstatement, whether due to error or fraud, and whether effective internal 
control over financial reporting was maintained in all material respects.

Our  audits  of  the  consolidated  financial  statements  included  performing  procedures  to  assess  the  risks  of 
material  misstatement  of  the  consolidated  financial  statements,  whether  due  to  error  or  fraud,  and 
performing  procedures  that  respond  to  those  risks.  Such  procedures  included  examining,  on  a  test  basis, 
evidence  regarding  the  amounts  and  disclosures  in  the  consolidated  financial  statements.  Our  audits  also 
included evaluating the accounting principles used and significant estimates made by management, as well 
as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control 
over  financial  reporting  included  obtaining  an  understanding  of  internal  control  over  financial  reporting, 
assessing  the  risk  that  a  material  weakness  exists,  and  testing  and  evaluating  the  design  and  operating 
effectiveness of internal control based on the assessed risk. Our audits also included performing such other 
procedures  as  we  considered  necessary  in  the  circumstances.  We  believe  that  our  audits  provide  a 
reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance 
regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external 
purposes in accordance with generally accepted accounting principles. A company’s internal control over 
financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, 
in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the 
company;  (ii)  provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit 
preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that 
receipts  and  expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of 
management and directors of the company; and (iii) provide reasonable assurance regarding prevention or 
timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a 
material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect 
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk 
that  controls  may  become  inadequate  because  of  changes  in  conditions,  or  that  the  degree  of  compliance 
with the policies or procedures may deteriorate.

Critical Audit Matters

The  critical  audit  matters  communicated  below  are  matters  arising  from  the  current  period  audit  of  the 
consolidated  financial  statements  that  were  communicated  or  required  to  be  communicated  to  the  audit 
committee  and  that  (i)  relate  to  accounts  or  disclosures  that  are  material  to  the  consolidated  financial 
statements  and  (ii)  involved  our  especially  challenging,  subjective,  or  complex  judgments.  The 
communication of critical audit matters does not alter in any way our opinion on the consolidated financial 
statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing 
separate opinions on the critical audit matters or on the accounts or disclosures to which they relate. 

Long-Lived Asset Recoverability Tests – Refinery Asset Groups

As described in Notes 2 and 7 to the consolidated financial statements and as disclosed by management, the 
Company’s consolidated long-lived asset balance was $43 billion as of December 31, 2020, which includes 
the refinery asset groups within the Refining & Marketing segment. Management reviews long-lived assets 
for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset 
group may not be recoverable. If the sum of the undiscounted estimated pretax cash flows is less than the 
carrying  value  of  an  asset  group,  fair  value  is  determined,  and  the  carrying  value  is  written  down  to  the 
determined fair value. During the first and second quarters of 2020, management identified long-lived asset 
triggers relating to all of their refinery asset groups, except the Gallup refinery in the second quarter as it 
had been impaired to its estimated salvage value in the first quarter, as a result of decreases to the Refining 
&  Marketing  segment  expected  future  cash  flows.  The  cash  flows  associated  with  these  assets  were 
significantly impacted by the effects of COVID-19 and commodity price declines in the first quarter and 
continued  unfavorable  macroeconomic  conditions  in  the  second  quarter.  Management  performed 
recoverability  tests  for  each  refinery  asset  group  by  comparing  the  undiscounted  estimated  pretax  cash 
flows to the carrying value of each asset group. The determination of undiscounted estimated pretax cash 
flows  for  the  first  and  second  quarter  refinery  asset  group  recoverability  tests  utilized  significant 
assumptions  including  management’s  best  estimates  of  the  expected  future  cash  flows,  allocation  of 
Refining & Marketing segment cash flows to the individual refinery asset groups, the estimated useful life 
of certain refinery asset groups, and the estimated salvage value of certain refinery asset groups. 

The  principal  considerations  for  our  determination  that  performing  procedures  relating  to  the  long-lived 
asset  recoverability  tests  of  the  refinery  asset  groups  performed  by  management  in  the  first  and  second 
quarters of 2020 is a critical audit matter are (i) the significant judgment by management when developing 
the  undiscounted  estimated  pretax  cash  flows  of  the  refinery  asset  groups;  and  (ii)  the  high  degree  of 
auditor  judgment,  subjectivity,  and  effort  in  performing  procedures  and  evaluating  management’s 
recoverability tests and the significant assumption related to allocation of Refining & Marketing segment 
cash flows to individual refinery asset groups.

Addressing  the  matter  involved  performing  procedures  and  evaluating  audit  evidence  in  connection  with 
forming our overall opinion on the consolidated financial statements. These procedures included testing the 
effectiveness of controls relating to management’s long-lived asset recoverability tests, including controls 
over the allocation of the undiscounted estimates of pretax cash flows to individual refinery asset groups. 

92

These  procedures  also  included,  among  others  (i)  testing  management’s  process  for  developing  the 
undiscounted  estimated  pretax  cash  flows  utilized  for  the  recoverability  tests;  (ii)  evaluating  the 
appropriateness of the undiscounted estimated pretax cash flow model used; (iii) testing the completeness 
and accuracy of underlying data used by management in the model; and (iv) evaluating the reasonableness 
of  the  significant  assumption  related  to  the  allocation  of  Refining  &  Marketing  segment  cash  flows  to 
individual  refineries.  Evaluating  the  reasonableness  of  this  significant  assumption  involved  (i)  evaluating 
the appropriateness of management’s allocation of Refining & Marketing segment cash flows to individual 
refinery  asset  groups;  (ii)  evaluating  the  appropriateness,  completeness,  and  accuracy  of  underlying  data 
used  to  allocate  Refining  &  Marketing  segment  cash  flows  to  individual  refinery  asset  groups;  and  (iii) 
considering whether the data used in the allocation was consistent with evidence obtained in other areas of 
the  audit.  Professionals  with  specialized  skill  and  knowledge  were  utilized  to  assist  in  evaluating  the 
appropriateness of the Company’s undiscounted estimated pretax cash flow model.

Goodwill Impairment Tests – Certain Midstream Reporting Units

As described in Notes 7 and 19 to the consolidated financial statements and as disclosed by management, 
the  Company’s  consolidated  goodwill  balance  was  $8,256  million  as  of  December  31,  2020,  which 
includes, within the Midstream segment, the goodwill associated with MPLX’s Crude Gathering reporting 
unit of $1.1 billion. As described by management, within the Midstream segment, the Company recorded 
an impairment charge of $1.81 billion in the first quarter of 2020 related to MPLX’s Eastern Gathering & 
Processing  reporting  unit,  which  fully  impaired  the  reporting  unit’s  historical  goodwill  balance. 
Management annually evaluates goodwill for impairment as of November 30, as well as whenever events 
or changes in circumstances indicate it is more likely than not that the fair value of a reporting unit with 
goodwill is less than its carrying amount. The overall deterioration in the economy and the environment in 
which  MPLX  and  its  customers  operate,  as  well  as  a  sustained  decrease  in  the  MPLX  unit  price,  were 
considered triggering events requiring an impairment test during the first quarter of 2020. The fair values of 
the  reporting  units  were  determined  based  on  applying  both  a  discounted  cash  flow  method,  or  income 
approach,  as  well  as  a  market  approach.  Significant  assumptions  that  were  used  to  estimate  the  MPLX 
Eastern  Gathering  and  Processing  and  MPLX  Crude  Gathering  reporting  units’  fair  values  under  the 
discounted  cash  flow  method  included  management’s  best  estimates  of  the  discount  rate,  as  well  as 
estimates of future cash flows, which are impacted primarily by producer customers’ development plans, 
which impact future volumes and capital requirements.

The  principal  considerations  for  our  determination  that  performing  procedures  relating  to  the  goodwill 
impairment tests of the Company’s Crude Gathering and Eastern Gathering and Processing reporting units 
of the Midstream segment is a critical audit matter are (i) the significant judgment by management when 
estimating the fair value of the reporting units; and (ii) the high degree of auditor judgment, subjectivity, 
and effort in performing procedures and evaluating management’s significant assumption related to future 
volumes.

Addressing  the  matter  involved  performing  procedures  and  evaluating  audit  evidence  in  connection  with 
forming our overall opinion on the consolidated financial statements. These procedures included testing the 
effectiveness of controls relating to management’s goodwill impairment tests, including controls over the 
estimation of the fair value of the Crude Gathering and Eastern Gathering and Processing reporting units. 
These  procedures  also  included,  among  others  (i)  testing  management’s  process  for  developing  the  fair 
value estimates; (ii) evaluating the appropriateness of the income and market approaches used; (iii) testing 
the  completeness  and  accuracy  of  underlying  data  used  by  management  in  the  approaches;  and  (iv) 
evaluating  the  reasonableness  of  the  significant  assumption  related  to  future  volumes.  Professionals  with 
specialized skill and knowledge were utilized to assist in evaluating the appropriateness of the Company’s 
income  and  market  approaches.  Evaluating  the  assumption  related  to  future  volumes  involved  (i) 
considering  whether  the  assumption  used  was  reasonable  considering  past  performance  of  each  reporting 
unit, producer customers’ historical and future production volumes, and industry outlook reports; and (ii) 
considering whether the assumption was consistent with evidence obtained in other areas of the audit. 

Equity Method Investment Impairment Test - MarkWest Utica EMG, L.L.C.

As described in Notes 7 and 17 to the consolidated financial statements, the Company’s consolidated equity 
method investment balance was $5,422 million as of December 31, 2020, which included a balance of $698 
million related to MarkWest Utica EMG, L.L.C. During the first quarter of 2020, the Company recorded an 
impairment charge of $1.25 billion related to MarkWest Utica EMG, L.L.C. As disclosed by management, 
equity method investments are assessed for impairment whenever factors indicate an other than temporary 

93

loss in value. As a result of the overall deterioration in the economy and the environment in which MPLX 
and its customers operate, there was a reduction in forecasted volumes processed by the systems operated 
by  MarkWest  Utica  EMG,  L.L.C.  These  were  considered  events  requiring  an  impairment  test  during  the 
first quarter of 2020. The fair value of the investment was determined based on applying a discounted cash 
flow method, an income approach. Significant assumptions that were used to develop the estimate of the 
fair  value  under  the  discounted  cash  flow  method  include  management’s  best  estimates  of  the  expected 
future  cash  flows,  including  prices  and  volumes,  the  weighted  average  cost  of  capital  and  the  long-term 
growth rate.

The  principal  considerations  for  our  determination  that  performing  procedures  relating  to  the  impairment 
test of the Company’s equity method investment in MarkWest Utica EMG, L.L.C. is a critical audit matter 
are (i) the significant judgment by management when estimating the fair value of the investment; and (ii) 
the  high  degree  of  auditor  judgment,  subjectivity,  and  effort  in  performing  procedures  and  evaluating 
management’s significant assumption related to future volumes.

Addressing  the  matter  involved  performing  procedures  and  evaluating  audit  evidence  in  connection  with 
forming our overall opinion on the consolidated financial statements. These procedures included testing the 
effectiveness  of  controls  relating  to  management’s  equity  method  investment  impairment  test,  including 
controls  over  the  estimation  of  the  fair  value  of  the  investment  in  MarkWest  Utica  EMG,  L.L.C.  These 
procedures  also  included,  among  others  (i)  testing  management’s  process  for  developing  the  fair  value 
estimate;  (ii)  evaluating  the  appropriateness  of  the  discounted  cash  flow  method  used;  (iii)  testing  the 
completeness and accuracy of underlying data used by management in the method; and (iv) evaluating the 
reasonableness of the significant assumption related to future volumes. Evaluating the assumption related to 
future  volumes  involved  (i)  considering  whether  the  assumption  used  was  reasonable  considering  past 
performance  of  MarkWest  Utica  EMG,  L.L.C.,  producer  customers’  historical  and  future  production 
volumes,  and  industry  outlook  reports;  and  (ii)  considering  whether  the  assumption  was  consistent  with 
evidence obtained in other areas of the audit.

1.  DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION 

Description of the Business 

We are a leading, integrated, downstream energy company headquartered in Findlay, Ohio. We operate the 
nation's  largest  refining  system.  We  sell  refined  products  to  wholesale  marketing  customers  domestically 
and  internationally,  to  buyers  on  the  spot  market  and  to  independent  entrepreneurs  who  operate 
approximately 7,100 branded outlets. We also sell transportation fuel to consumers through approximately 
1,090 direct dealer locations under long-term supply contracts. MPC’s midstream operations are primarily 
conducted  through  MPLX  LP  (“MPLX”),  which  owns  and  operates  crude  oil  and  light  product 
transportation and logistics infrastructure as well as gathering, processing, and fractionation assets. We own 
the general partner and a majority limited partner interest in MPLX.

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

As a result of the agreement to sell Speedway, its results are reported separately as discontinued operations 
in our consolidated statements of income for all periods presented and its assets and liabilities have been 
presented in our consolidated balance sheets as assets and liabilities held for sale. In addition, we separately 
disclosed  the  operating  and  investing  cash  flows  of  Speedway  as  discontinued  operations  within  our 
consolidated statements of cash flow. See Note 5 for discontinued operations disclosures. 

Prior  to  presentation  of  Speedway  as  discontinued  operations,  Speedway  and  our  retained  direct  dealer 
business were the two reporting units within our Retail segment. Beginning with the third quarter of 2020, 
the  direct  dealer  business  is  managed  as  part  of  the  Refining  &  Marketing  segment.  The  results  of  the 
Refining & Marketing segment have been retrospectively adjusted to include the results of the direct dealer 
business in all periods presented. See Note 13 for our segment reporting disclosures.

Refer to Note 8 for further information on the Andeavor acquisition, which closed on October 1, 2018, and 
to Notes 6 and 13 for additional information about our operations.

Basis of Presentation 

All significant intercompany transactions and accounts have been eliminated.

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

•

•

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

Beginning  August  2,  2020,  in  accordance  with  ASC  360,  Property,  Plant,  and  Equipment,  we 
ceased  recording  depreciation  and  amortization  for  Speedway’s  property,  plant  and  equipment, 
finite-lived intangible assets and right of use lease assets.

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

2.   SUMMARY OF PRINCIPAL ACCOUNTING POLICIES 

Principles Applied in Consolidation

These consolidated financial statements include the accounts of our majority-owned, controlled subsidiaries 
and  MPLX.  As  of  December  31,  2020,  we  owned  the  general  partner  and  62  percent  of  the  outstanding 
MPLX common units. Due to our ownership of the general partner interest, we have determined that we 
control  MPLX  and  therefore  we  consolidate  MPLX  and  record  a  noncontrolling  interest  for  the  interest 
owned  by  the  public.  Changes  in  ownership  interest  in  consolidated  subsidiaries  that  do  not  result  in  a 
change in control are recorded as equity transactions. 

Investments in entities over which we have significant influence, but not control, are accounted for using 
the  equity  method  of  accounting.  This  includes  entities  in  which  we  hold  majority  ownership  but  the 
minority  shareholders  have  substantive  participating  rights.  Income  from  equity  method  investments 
represents our proportionate share of net income generated by the equity method investees.

Differences  in  the  basis  of  the  investments  and  the  separate  net  asset  values  of  the  investees,  if  any,  are 
amortized into net income over the remaining useful lives of the underlying assets and liabilities, except for 
any excess related to goodwill. Equity method investments are evaluated for impairment whenever changes 
in the facts and circumstances indicate an other than temporary loss in value has occurred. When the loss is 
deemed to be other than temporary, the carrying value of the equity method investment is written down to 
fair value.

Use of Estimates 

The  preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles 
requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets  and 
liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial 
statements and the reported amounts of revenues and expenses during the respective reporting periods.

Revenue Recognition

We recognize revenue based on consideration specified in contracts or agreements with customers when we 
satisfy  our  performance  obligations  by  transferring  control  over  products  or  services  to  a  customer. 
Concurrent with our adoption of ASU 2014-09, Revenue from Contracts with Customers (“ASC 606”), as 
of  January  1,  2018,  we  made  an  accounting  policy  election  that  all  taxes  assessed  by  a  governmental 
authority that are both imposed on and concurrent with a revenue-producing transaction and collected from 
our customers will be recognized on a net basis within sales and other operating revenues. 

Our revenue recognition patterns are described below by reportable segment:

•

Refining & Marketing - The vast majority of our Refining & Marketing contracts contain pricing 
that is based on the market price for the product at the time of delivery. Our obligations to deliver 
product  volumes  are  typically  satisfied  and  revenue  is  recognized  when  control  of  the  product 
transfers to our customers. Concurrent with the transfer of control, we typically receive the right to 
payment  for  the  delivered  product,  the  customer  accepts  the  product  and  the  customer  has 
significant risks and rewards of ownership of the product. Payment terms require customers to pay 
shortly after delivery and do not contain significant financing components. 

• Midstream  -  Midstream  revenue  transactions  typically  are  defined  by  contracts  under  which  we 
sell a product or provide a service. Revenues from sales of product are recognized when control of 
the  product  transfers  to  the  customer.  Revenues  from  sales  of  services  are  recognized  over  time 
when the performance obligation is satisfied as services are provided in a series. We have elected 
to use the output measure of progress to recognize revenue based on the units delivered, processed 
or  transported.  The  transaction  prices  in  our  Midstream  contracts  often  have  both  fixed 
components,  related  to  minimum  volume  commitments,  and  variable  components,  which  are 
primarily dependent on volumes. Variable consideration will generally not be estimated at contract 
inception as the transaction price is specifically allocable to the services provided at each period 
end. 

Refer to Note 23 for disclosure of our revenue disaggregated by segment and product line and to Note 13 
for a description of our reportable segment operations.

102

    
Crude Oil and Refined Product Exchanges and Matching Buy/Sell Transactions 

We  enter  into  exchange  contracts  and  matching  buy/sell  arrangements  whereby  we  agree  to  deliver  a 
particular quantity and quality of crude oil or refined products at a specified location and date to a particular 
counterparty and to receive from the same counterparty the same commodity at a specified location on the 
same or another specified date. The exchange receipts and deliveries are nonmonetary transactions, with the 
exception  of  associated  grade  or  location  differentials  that  are  settled  in  cash.  The  matching  buy/sell 
purchase  and  sale  transactions  are  settled  in  cash.  No  revenues  are  recorded  for  exchange  and  matching 
buy/sell  transactions  as  they  are  accounted  for  as  exchanges  of  inventory.  The  exchange  transactions  are 
recognized at the carrying amount of the inventory transferred.

Cash and Cash Equivalents 

Cash  and  cash  equivalents  include  cash  on  hand  and  on  deposit  and  investments  in  highly  liquid  debt 
instruments with maturities of three months or less.

Restricted Cash 

Restricted cash consists of cash and investments that must be maintained as collateral for letters of credit 
issued  to  certain  third-party  producer  customers.  The  balances  will  be  outstanding  until  certain  capital 
projects are completed and the third party releases the restriction. 

Accounts Receivable and Allowance for Doubtful Accounts 

Our receivables primarily consist of customer accounts receivable. Customer receivables are recorded at the 
invoiced  amounts  and  generally  do  not  bear  interest.  Allowances  for  doubtful  accounts  are  generally 
recorded when it becomes probable the receivable will not be collected and are booked to bad debt expense. 
The allowance for doubtful accounts is the best estimate of the amount of probable credit losses in customer 
accounts receivable. We review the allowance quarterly and past-due balances over 180 days are reviewed 
individually for collectability. 

We mitigate credit risk with master netting agreements with companies engaged in the crude oil or refinery 
feedstock  trading  and  supply  business  or  the  petroleum  refining  industry.  A  master  netting  agreement 
generally  provides  for  a  once  per  month  net  cash  settlement  of  the  accounts  receivable  from  and  the 
accounts payable to a particular counterparty.

Leases 

Contracts with a term greater than one year that convey the right to direct the use of and obtain substantially 
all of the economic benefit of an asset are accounted for as right of use assets.

Right of use asset and lease liability balances are recorded at the commencement date at present value of 
the  fixed  lease  payments  using  a  secured  incremental  borrowing  rate  with  a  maturity  similar  to  the  lease 
term because our leases do not provide implicit rates. We have elected to include both lease and non-lease 
components in the present value of the lease payments for all lessee asset classes with the exception of our 
marine  and  third-party  contractor  service  equipment  leases.  The  lease  component  of  the  payment  for  the 
marine and equipment asset classes is determined using a relative standalone selling price. See Note 28 for 
additional disclosures about our lease contracts.

Inventories

Inventories  are  carried  at  the  lower  of  cost  or  market  value.  Cost  of  inventories  is  determined  primarily 
under  the  LIFO  method.  Costs  for  crude  oil  and  refined  product  inventories  are  aggregated  on  a 
consolidated  basis  for  purposes  of  assessing  if  the  LIFO  cost  basis  of  these  inventories  may  have  to  be 
written down to market value.

Derivative Instruments 

We  use  derivatives  to  economically  hedge  a  portion  of  our  exposure  to  commodity  price  risk  and, 
historically,  to  interest  rate  risk.  Our  use  of  selective  derivative  instruments  that  assume  market  risk  is 
limited.  All  derivative  instruments  (including  derivative  instruments  embedded  in  other  contracts)  are 
recorded at fair value. Certain commodity derivatives are reflected on the consolidated balance sheets on a 
net  basis  by  counterparty  as  they  are  governed  by  master  netting  agreements.  Cash  flows  related  to 
derivatives used to hedge commodity price risk and interest rate risk are classified in operating activities 
with the underlying transactions.

103

Derivatives not designated as accounting hedges 

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,  (6)  the 
purchase  of  natural  gas  and  (7)  the  purchase  of  soybean  oil.  Changes  in  the  fair  value  of  derivatives  not 
designated as accounting hedges are recognized immediately in net income.

Concentrations of credit risk 

All of our financial instruments, including derivatives, involve elements of credit and market risk. The most 
significant portion of our credit risk relates to nonperformance by counterparties. The counterparties to our 
financial  instruments  consist  primarily  of  major  financial  institutions  and  companies  within  the  energy 
industry.  To  manage  counterparty  risk  associated  with  financial  instruments,  we  select  and  monitor 
counterparties  based  on  an  assessment  of 
if 
available. Additionally, we limit the level of exposure with any single counterparty.

their  financial  strength  and  on  credit  ratings, 

Property, Plant and Equipment 

Property,  plant  and  equipment  are  recorded  at  cost  and  depreciated  on  a  straight-line  basis  over  the 
estimated useful lives of the assets, which range from one year to 61 years. Such assets are reviewed for 
impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  an  asset 
group may not be recoverable. If the sum of the expected undiscounted future cash flows from the use of 
the  asset  group  and  its  eventual  disposition  is  less  than  the  carrying  amount  of  the  asset  group,  an 
impairment assessment is performed and the excess of the book value over the fair value of the asset group 
is recorded as an impairment loss.

When  items  of  property,  plant  and  equipment  are  sold  or  otherwise  disposed  of,  any  gains  or  losses  are 
reported in net income. Gains on the disposal of property, plant and equipment are recognized when earned, 
which is generally at the time of closing. If a loss on disposal is expected, such losses are recognized when 
the assets are classified as held for sale.

Interest  expense  is  capitalized  for  qualifying  assets  under  construction.  Capitalized  interest  costs  are 
included in property, plant and equipment and are depreciated over the useful life of the related asset.

Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired 
in  the  acquisition  of  a  business.  Goodwill  is  not  amortized,  but  rather  is  tested  for  impairment  at  the 
reporting unit level annually and when events or changes in circumstances indicate that the fair value of a 
reporting unit with goodwill has been reduced below carrying value. If we determine, based on a qualitative 
assessment,  that  it  is  not  more  likely  than  not  that  a  reporting  unit’s  fair  value  is  less  than  its  carrying 
amount, no further impairment testing is required. If we do not perform a qualitative assessment or if that 
assessment  indicates  that  further  impairment  testing  is  required,  the  fair  value  of  each  reporting  unit  is 
determined  using  an  income  and/or  market  approach  which  is  compared  to  the  carrying  value  of  the 
reporting unit. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss would 
be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that 
reporting unit. The fair value under the income approach is calculated using the expected present value of 
future  cash  flows  method.  Significant  assumptions  used  in  the  cash  flow  forecasts  include  future  net 
operating margins, future volumes, discount rates, and future capital requirements.

Amortization  of  intangibles  with  definite  lives  is  calculated  using  the  straight-line  method,  which  is 
reflective of the benefit pattern in which the estimated economic benefit is expected to be received over the 
estimated useful life of the intangible asset. Intangibles subject to amortization are reviewed for impairment 
whenever events or changes in circumstances indicate that the carrying amount of the intangible may not be 
recoverable. If the sum of the expected undiscounted future cash flows related to the asset is less than the 
carrying  amount  of  the  asset,  an  impairment  loss  is  recognized  based  on  the  fair  value  of  the  asset. 
Intangibles not subject to amortization are tested for impairment annually and when circumstances indicate 
that the fair value is less than the carrying amount of the intangible. If the fair value is less than the carrying 
value, an impairment is recorded for the difference.

104

Major Maintenance Activities 

Costs  for  planned  turnaround  and  other  major  maintenance  activities  are  expensed  in  the  period 
incurred. These types of costs include contractor repair services, materials and supplies, equipment rentals 
and our labor costs.

Environmental Costs 

Environmental  expenditures  for  additional  equipment  that  mitigates  or  prevents  future  contamination  or 
improves  environmental  safety  or  efficiency  of  the  existing  assets  are  capitalized.  We  recognize 
remediation  costs  and  penalties  when  the  responsibility  to  remediate  is  probable  and  the  amount  of 
associated costs can be reasonably estimated. The timing of remediation accruals coincides with completion 
of  a  feasibility  study  or  the  commitment  to  a  formal  plan  of  action.  Remediation  liabilities  are  accrued 
based on estimates of known environmental exposure and are discounted when the estimated amounts are 
reasonably  fixed  and  determinable.  If  recoveries  of  remediation  costs  from  third  parties  are  probable,  a 
receivable is recorded and is discounted when the estimated amount is reasonably fixed and determinable.

Asset Retirement Obligations 

The  fair  value  of  asset  retirement  obligations  is  recognized  in  the  period  in  which  the  obligations  are 
incurred if a reasonable estimate of fair value can be made. The majority of our recognized asset retirement 
liability  relates  to  conditional  asset  retirement  obligations  for  removal  and  disposal  of  fire-retardant 
material from certain refining facilities. The remaining recognized asset retirement liability relates to other 
refining assets, certain pipelines and processing facilities and other related pipeline assets. The fair values 
recorded for such obligations are based on the most probable current cost projections.

Asset  retirement  obligations  have  not  been  recognized  for  some  assets  because  the  fair  value  cannot  be 
reasonably estimated since the settlement dates of the obligations are indeterminate. Such obligations will 
be recognized in the period when sufficient information becomes available to estimate a range of potential 
settlement  dates.  The  asset  retirement  obligations  principally  include  the  hazardous  material  disposal  and 
removal  or  dismantlement  requirements  associated  with  the  closure  of  certain  refining,  terminal,  pipeline 
and processing assets.

Our practice is to keep our assets in good operating condition through routine repair and maintenance of 
component  parts  in  the  ordinary  course  of  business  and  by  continuing  to  make  improvements  based  on 
technological advances. As a result, we believe that generally these assets have no expected settlement date 
for  purposes  of  estimating  asset  retirement  obligations  since  the  dates  or  ranges  of  dates  upon  which  we 
would retire these assets cannot be reasonably estimated at this time.

Income Taxes 

Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to 
differences  between  the  financial  statement  carrying  amounts  of  assets  and  liabilities  and  their  tax 
bases.  Deferred  tax  assets  are  recorded  when  it  is  more  likely  than  not  that  they  will  be  realized.  The 
realization of deferred tax assets is assessed periodically based on several factors, primarily our expectation 
to generate sufficient future taxable income.

Stock-Based Compensation Arrangements 

The fair value of stock options granted to our employees is estimated on the date of grant using the Black-
Scholes option pricing model. The model employs various assumptions based on management’s estimates 
at the time of grant, which impact the calculation of fair value and ultimately, the amount of expense that is 
recognized over the vesting period of the stock option award. Of the required assumptions, the expected life 
of the stock option award and the expected volatility of our stock price have the most significant impact on 
the  fair  value  calculation.  The  average  expected  life  is  based  on  our  historical  employee  exercise 
behavior. The assumption for expected volatility of our stock price reflects a weighting of 50 percent of our 
common stock implied volatility and 50 percent of our common stock historical volatility.

The fair value of restricted stock awards granted to our employees is determined based on the fair market 
value of our common stock on the date of grant. The fair value of performance unit awards granted to our 
employees is estimated on the date of grant using a Monte Carlo valuation model.

105

Our stock-based compensation expense is recognized based on management’s estimate of the awards that 
are expected to vest, using the straight-line attribution method for all service-based awards with a graded 
vesting  feature.  If  actual  forfeiture  results  are  different  than  expected,  adjustments  to  recognized 
compensation expense may be required in future periods. Unearned stock-based compensation is charged to 
equity  when  restricted  stock  awards  are  granted.  Compensation  expense  is  recognized  over  the  vesting 
period and is adjusted if conditions of the restricted stock award are not met. 

Business Combinations 

We recognize and measure the assets acquired and liabilities assumed in a business combination based on 
their estimated fair values at the acquisition date. Any excess or surplus of the purchase consideration when 
compared to the fair value of the net tangible assets acquired, if any, is recorded as goodwill or gain from a 
bargain  purchase.  For  material  acquisitions,  management  engages  an  independent  valuation  specialist  to 
assist with the determination of fair value of the assets acquired, liabilities assumed, noncontrolling interest, 
if  any,  and  goodwill,  based  on  recognized  business  valuation  methodologies.  An  income,  market  or  cost 
valuation method may be utilized to estimate the fair value of the assets acquired, liabilities assumed, and 
noncontrolling  interest,  if  any,  in  a  business  combination.  The  income  valuation  method  represents  the 
present value of future cash flows over the life of the asset using: (i) discrete financial forecasts, which rely 
on  management’s  estimates  of  revenue  and  operating  expenses;  (ii)  long-term  growth  rates;  and 
(iii) appropriate discount rates. The market valuation method uses prices paid for a reasonably similar asset 
by other purchasers in the market, with adjustments relating to any differences between the assets. The cost 
valuation  method  is  based  on  the  replacement  cost  of  a  comparable  asset  at  prices  at  the  time  of  the 
acquisition  reduced  for  depreciation  of  the  asset.  If  the  initial  accounting  for  the  business  combination  is 
incomplete  by  the  end  of  the  reporting  period  in  which  the  acquisition  occurs,  an  estimate  will  be 
recorded. Subsequent to the acquisition date, and not later than one year from the acquisition date, we will 
record any material adjustments to the initial estimate based on new information obtained that would have 
existed as of the date of the acquisition. Any adjustment that arises from information obtained that did not 
exist as of the date of the acquisition will be recorded in the period of the adjustment. Acquisition-related 
costs are expensed as incurred in connection with each business combination. 

Environmental Credits and Obligations 

In order to comply with certain regulations, specifically the RFS2 requirements implemented by the EPA 
and the cap-and-trade emission reduction program and low carbon fuel standard implemented by the state 
of California, we are required to reduce our emissions, blend certain levels of biofuels or obtain allowances 
or credits to offset the obligations created by our operations. In regard to each program, we record an asset, 
included in other current or other noncurrent assets on the balance sheet, for allowances or credits owned in 
excess of our anticipated current period compliance requirements. The asset value is based on the product 
of the excess allowances or credits as of the balance sheet date, if any, and the weighted average cost of 
those allowances or credits. We record a liability, included in other current or other noncurrent liabilities on 
the balance sheet, when we are deficient allowances or credits based on the product of the deficient amount 
as of the balance sheet date, if any, and the market price of the allowances or credits at the balance sheet 
date. The cost of allowances or credits used for compliance is reflected in cost of revenues on the income 
statement.  Any  gains  or  losses  on  the  sale  or  expiration  of  allowances  or  credits  are  classified  as  other 
income on the income statement. Proceeds from the sale of allowances or credits are reported in investing 
activities - all other, net on the cash flow statement.

3.   ACCOUNTING STANDARDS 

Recently Adopted

Effective  January  1,  2020,  we  adopted  ASU  2016-13,  “Financial  Instruments-Credit  Losses  (Topic  326): 
Measurement  of  Credit  Losses  on  Financial  Instruments,”  using  the  modified  retrospective  transition 
method. The amendment requires entities to consider a broader range of information to estimate expected 
credit losses, which may result in earlier recognition of losses. The ASU requires the company to utilize an 
expected loss methodology in place of the incurred loss methodology for financial instruments, including 
trade receivables, and off-balance sheet credit exposures. Adoption of the standard did not have a material 
impact on our financial statements. 

106

                                                                                                
We  are  exposed  to  credit  losses  primarily  through  our  sales  of  refined  petroleum  products,  crude  oil  and 
midstream services. We assess each customer’s ability to pay through our credit review process. The credit 
review process considers various factors such as external credit ratings, a review of financial statements to 
determine  liquidity,  leverage,  trends  and  business  specific  risks,  market  information,  pay  history  and  our 
business strategy. Customers that do not qualify for payment terms are required to prepay or provide a letter 
of credit. We monitor our ongoing credit exposure through timely review of customer payment activity. At 
December 31, 2020, we reported $5,760 million of accounts and notes receivable, net of allowances of $18 
million.

We are also exposed to credit losses from off-balance sheet exposures, such as guarantees of joint venture 
debt. See Note 29 for more information on these off-balance sheet exposures.

We  also  adopted  the  following  ASUs  during  2020,  none  of  which  had  a  material  impact  to  our  financial 
statements or financial statement disclosures:

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

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

4.   RESTRUCTURING 

During  the  third  quarter  of  2020,  we  indefinitely  idled  our  refinery  located  in  Gallup,  New  Mexico  and 
initiated actions to strategically reposition our Martinez, California refinery to a renewable diesel facility. 
We also approved an involuntary workforce reduction plan. In connection with these strategic actions, we 
recorded restructuring expenses of $367 million in 2020. 

The indefinite idling of the Gallup refinery and actions to strategically reposition the Martinez refinery to a 
renewable  diesel  facility  resulted  in  $195  million  of  restructuring  expenses.  Of  the  $195  million  of 
restructuring  expenses,  we  expect  $130  million  to  settle  in  cash  for  costs  related  to  decommissioning 
refinery  processing  units  and  storage  tanks  and  fulfilling  environmental  remediation  obligations. 
Additionally, we recorded a non-cash reserve against our materials and supplies inventory at these facilities 
of $51 million. 

The  involuntary  workforce  reduction  plan,  together  with  employee  reductions  resulting  from  our  actions 
affecting the Gallup and Martinez refineries, affected approximately 2,050 employees. We recorded $172 
million of restructuring expenses for separation benefits payable under our employee separation plan and 
certain  collective  bargaining  agreements  that  we  expect  to  settle  in  cash.  Certain  of  the  affected  MPC 
employees provided services to MPLX. MPLX has various employee services agreements and secondment 
agreements  with  MPC  pursuant  to  which  MPLX  reimburses  MPC  for  employee  costs,  along  with  the 
provision  of  operational  and  management  services  in  support  of  MPLX’s  operations.  Pursuant  to  such 
agreements, MPC was reimbursed by MPLX for $37 million of the $172 million of restructuring expenses 
recorded for these actions.

Restructuring expenses were accrued as restructuring reserves within accounts payable, payroll and benefits 
payable,  other  current  liabilities  and  deferred  credits  and  other  liabilities  within  our  consolidated  balance 
sheets. We expect cash payments for the majority of these reserves to occur within the next nine months.

5.   DISCONTINUED OPERATIONS AND ASSETS HELD FOR SALE 

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

As a result of the agreement to sell Speedway, its results are reported separately as discontinued operations, 
net of tax, in our consolidated statements of income for all periods presented and its assets and liabilities 
have been presented in our consolidated balance sheets as assets and liabilities held for sale. Additionally, 
beginning  August  2,  2020,  in  accordance  with  ASC  360,  Property,  Plant,  and  Equipment,  we  ceased 
recording  depreciation  and  amortization  for  Speedway’s  property,  plant  and  equipment,  finite-lived 
intangible  assets  and  right  of  use  lease  assets.  In  addition,  we  separately  disclosed  the  operating  and 
investing  cash  flows  of  Speedway  as  discontinued  operations  within  our  consolidated  statements  of  cash 
flow.

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

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

Purchase of Speedway’s Interest in PFJ Southeast

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

6.  MASTER LIMITED PARTNERSHIP

We  own  the  general  partner  and  a  majority  limited  partner  interest  in  MPLX,  which  owns  and  operates 
crude oil and light product transportation and logistics infrastructure as well as gathering, processing, and 
fractionation  assets.  We  control  MPLX  through  our  ownership  of  the  general  partner  interest  and,  as  of 
December 31, 2020, we owned approximately 62 percent of the outstanding MPLX common units. 

Javelina Assets Held-for-Sale

On December 23, 2020, MPLX entered into an agreement with a third party to sell all of its equity interests 
in MarkWest Javelina Company, L.L.C., MarkWest Javelina Pipeline Company, L.L.C. and MarkWest Gas 
Services, L.L.C. (collectively, “Javelina”). Javelina’s assets and liabilities have been presented within our 
consolidated balance sheets as assets and liabilities held for sale as of December 31, 2020. On February 12, 
2021, MPLX completed the sale of Javelina.

Unit Repurchase Program

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

During the year ended December 31, 2020, 1,473,843 common units had been repurchased at an average 
cost  per  unit  of  $22.29.  Total  cash  paid  for  units  repurchased  during  the  year  was  $33  million  and  $967 
million  remained  outstanding  on  the  program  for  future  repurchases  as  of  December  31,  2020.  As  of 
December  31,  2020,  MPLX  had  agreements  to  acquire  99,406  additional  common  units  for  $2  million, 
which settled in early January 2021.

Redemption of Business from MPLX

On  July  31,  2020,  Western  Refining  Southwest,  Inc.  (now  known  as  Western  Refining  Southwest  LLC) 
(“WRSW”), a wholly owned subsidiary of MPC, entered into a Redemption Agreement (the “Redemption 
Agreement”)  with  MPLX,  pursuant  to  which  MPLX  transferred  to  WRSW  all  of  the  outstanding 
membership interests in Western Refining Wholesale, LLC, (“WRW”) in exchange for the redemption of 
MPLX  common  units  held  by  WRSW.  The  transaction  effects  the  transfer  to  MPC  of  the  Western 
wholesale distribution business that MPLX acquired as a result of its acquisition of Andeavor Logistics LP 
(“ANDX”). Beginning in the third quarter of 2020, the results of these operations are presented in MPC’s 
Refining & Marketing segment.

At  the  closing,  per  the  terms  of  Redemption  Agreement,  MPLX  redeemed  18,582,088  MPLX  common 
units (the “Redeemed Units”) held by WRSW. The number of Redeemed Units was calculated by dividing 
WRW’s aggregate valuation of $340 million by the simple average of the volume weighted average NYSE 
prices  of  an  MPLX  common  unit  for  the  ten  trading  days  ending  at  market  close  on  July  27,  2020.  The 
transaction resulted in a minor decrease in MPC’s ownership interest in MPLX.

MPLX’s Acquisition of ANDX

On  July  30,  2019,  MPLX  completed  its  acquisition  of  ANDX,  and  ANDX  survived  as  a  wholly  owned 
subsidiary of MPLX. At the effective time of the ANDX acquisition, each common unit held by ANDX’s 
public  unitholders  was  converted  into  the  right  to  receive  1.135  MPLX  common  units.  ANDX  common 
units held by MPC were converted into the right to receive 1.0328 MPLX common units. Additionally, as a 
result  of  MPLX’s  acquisition  of  MPLX,  600,000  ANDX  preferred  units  were  converted  into  600,000 
preferred units of MPLX (“Series B preferred units”). Series B preferred unitholders are entitled to receive, 
when and if declared by the board of directors of MPLX’s general partner, a fixed distribution of $68.75 
per unit, per annum, payable semi-annually in arrears on February 15 and August 15, or the first business 
day  thereafter,  up  to  and  including  February  15,  2023.  After  February  15,  2023,  the  holders  of  Series  B 
preferred units are entitled to receive cumulative, quarterly distributions payable in arrears on the 15th day 
of  February,  May,  August  and  November  of  each  year,  or  the  first  business  day  thereafter,  based  on  a 
floating annual rate equal to the three month LIBOR plus 4.652 percent. 

MPC  accounted  for  this  transaction  as  a  common  control  transaction,  as  defined  by  ASC  805,  which 
resulted  in  an  increase  to  noncontrolling  interest  and  a  decrease  to  additional  paid-in  capital  of 
approximately  $55  million,  net  of  tax.  During  the  third  quarter  of  2019,  we  pushed  down  to  MPLX  the 
portion  of  the  goodwill  attributable  to  ANDX  as  of  October  1,  2018,  the  date  of  our  acquisition  of 
Andeavor. Due to this push down of goodwill, we also recorded an incremental $642 million deferred tax 
liability  associated  with  the  portion  of  the  non-deductible  goodwill  attributable  to  the  noncontrolling 
interest  in  MPLX  with  an  offsetting  reduction  of  our  additional  paid-in  capital  balance.  We  have 
consolidated ANDX since we acquired Andeavor on October 1, 2018 in accordance with ASC 810.

Dropdowns to MPLX and GP/IDR Exchange

On February 1, 2018, we contributed our 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 a $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.

Agreements

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

Noncontrolling Interest

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

Increase due to the issuance of MPLX common units and general 
partner units to MPC

IMPAIRMENTS 

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

During the first quarter of 2020, the overall deterioration in the economy and the environment in which we 
operate, the related changes to our expected future cash flows, as well as a sustained decrease in share price 
were considered triggering events requiring the performance of various tests of the carrying values of our 
assets. Triggering events requiring the performance of various tests of the carrying value of our Midstream 

111

 
 
 
 
 
 
 
 
 
assets  were  also  identified  by  MPLX  as  a  result  of  the  overall  deterioration  in  the  economy  and  the 
environment  in  which  MPLX  and  its  customers  operate,  which  led  to  a  reduction  in  forecasted  volumes 
processed by the systems operated by MarkWest Utica EMG, L.L.C., MPLX’s equity method investee, as 
well as a sustained decrease in the MPLX unit price. These tests resulted in the majority of the impairment 
charges in 2020, as discussed below. 

The table below provides information related to the impairments recognized during 2020 and 2019, along 
with the location of these impairments within the consolidated statements of income.

The remaining difference not described in the narrative below is related to certain immaterial Midstream assets. 

Goodwill

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

During the third quarter of 2020, we recorded an impairment of goodwill of $64 million. The $64 million of 
goodwill  was  transferred  from  our  Midstream  segment  to  our  Refining  &  Marketing  segment  during  the 
third quarter of 2020 in connection with the transfer to MPC of the MPLX wholesale distribution business 
as  described  in  Note  6.  The  transfer  required  goodwill  impairment  tests  for  the  transferor  and  transferee 
reporting units. Our Refining & Marketing reporting unit that recorded the $64 million impairment expense 
has no remaining goodwill.

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

During the fourth quarter of 2019, we recorded an impairment of goodwill in our Midstream segment. As a 
result  of  the  merger  of  MPLX  and  ANDX  in  2019  and  subsequent  changes  to  MPLX’s  internal 
organization structure, the number of reporting units within our Midstream segment was reduced from 16 to 
7 in conjunction with the annual impairment test, however, this change in structure did not have any impact 
on  MPC’s  operating  segments.  Reporting  units  are  determined  based  on  the  way  in  which  segment 
management  operates  and  reviews  each  operating  segment.  MPLX  performed  a  goodwill  impairment 
assessment  prior  to  the  change  in  reporting  units  in  addition  to  performing  an  impairment  assessment 
immediately  following  the  change  in  their  reporting  units.  Significant  assumptions  used  to  estimate  the 
reporting  units’  fair  value  include  the  discount  rate  as  well  as  estimates  of  future  cash  flows,  which  are 
impacted  primarily  by  producer  customers’  development  plans,  which  impact  future  volumes  and  capital 
requirements. After MPLX performed its evaluations related to the impairment of goodwill, we recorded an 
impairment  of  $1,156  million  prior  to  the  change  in  reporting  units  and  additional  impairment  of  $41 
million subsequent to the change in reporting units. The remainder of the reporting units fair values were in 

112

 
 
 
 
excess of their carrying values. The impairment was primarily driven by the updated guidance related to the 
slowing  of  drilling  activity  which  has  reduced  production  growth  forecasts  from  MPLX’s  producer 
customers.

The  fair  value  of  the  reporting  units  for  the  fourth  quarter  of  2019  goodwill  impairment  analysis  was 
determined  based  on  applying  both  a  discounted  cash  flow  or  income  approach  as  well  as  a  market 
approach. The discounted cash flow fair value estimate is based on known or knowable information at the 
measurement date. The significant assumptions that were used to develop the estimates of the fair values 
under the discounted cash flow method included management’s best estimates of the expected future results 
and  discount  rates,  which  range  from  9.0  percent  to  10.0  percent.  Fair  value  determinations  require 
considerable  judgment  and  are  sensitive  to  changes  in  underlying  assumptions  and  factors.  As  a  result, 
there  can  be  no  assurance  that  the  estimates  and  assumptions  made  for  purposes  of  the  annual  goodwill 
impairment test will prove to be an accurate prediction of the future. The fair value measurements for the 
individual reporting units’ overall fair values, and the fair values of the goodwill assigned thereto, represent 
Level 3 measurements.

Equity Method Investments

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

During the fourth quarter of 2019, two joint ventures in which MPLX has an interest recorded impairments, 
which impacted the amount of income from equity method investments during the period by approximately 
$28 million. For one of the joint ventures, MPLX also had a basis difference which was being amortized 
over the life of the underlying assets. As a result of the impairment recorded by the joint venture, MPLX 
also assessed this basis difference for impairment and recorded approximately $14 million of impairment 
expense during the fourth quarter related to this investment.

Long-lived Assets

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

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

113

During the second quarter of 2020, we identified long-lived asset impairment triggers relating to all of our 
refinery asset groups within the Refining & Marketing segment, except the Gallup refinery as it had been 
impaired  to  its  estimated  salvage  value  in  the  first  quarter,  as  a  result  of  continued  unfavorable 
macroeconomic conditions impacting the Refining & Marketing segment expected future cash flows. We 
performed  recoverability  tests  for  each  refinery  asset  group  by  comparing  the  undiscounted  estimated 
pretax cash flows to the carrying value of each asset group. All of these refinery asset groups’ undiscounted 
estimated pretax cash flows exceeded their carrying value by at least 17 percent. 

The  determination  of  undiscounted  estimated  pretax  cash  flows  for  the  first  and  second  quarter  refinery 
asset group recoverability tests utilized significant assumptions including management’s best estimates of 
the  expected  future  cash  flows,  allocation  of  certain  Refining  &  Marketing  segment  cash  flows  to  the 
individual refinery asset groups, the estimated useful life of certain refinery asset groups, and the estimated 
salvage value of certain refinery asset groups. 

On  August  3,  2020,  we  announced  our  plans  to  evaluate  possibilities  to  strategically  reposition  our 
Martinez  refinery,  including  the  potential  conversion  of  the  refinery  into  a  renewable  diesel  facility. 
Subsequent  to  August  3,  2020,  we  progressed  activities  associated  with  the  conversion  of  the  Martinez 
refinery to a renewable diesel facility, including applying for permits, advancing discussions with feedstock 
suppliers,  and  beginning  detailed  engineering  activities.  As  envisioned,  the  Martinez  facility  would  start 
producing approximately 260 million gallons per year of renewable diesel by the second half of 2022, with 
a potential to build to full capacity of approximately 730 million gallons per year by the end of 2023. As a 
result of the progression of these activities, we identified assets that would be repurposed and utilized in a 
renewable diesel facility configuration and assets that would be abandoned since they had no function in a 
renewable diesel facility configuration. This change in our intended use for the Martinez refinery is a long-
lived asset impairment trigger for the assets that would be repurposed and remain as part of the Martinez 
asset group. We assessed the asset group for impairment by comparing the undiscounted estimated pretax 
cash  flows  to  the  carrying  value  of  the  asset  group  and  the  undiscounted  estimated  pretax  cash  flows 
exceeded the Martinez asset group carrying value. We recorded impairment expense of $342 million for the 
abandoned assets as we are no longer using these assets and have no expectation to use these assets in the 
future.  Additionally,  as  a  result  of  our  efforts  to  progress  the  conversion  of  Martinez  refinery  into  a 
renewable  diesel  facility,  MPLX  cancelled  in-process  capital  projects  related  to  its  Martinez  refinery 
logistics operations resulting in impairments of $27 million in the third quarter of 2020. 

In the fourth quarter of 2020, we concluded the evaluation of our intended use of MPLX terminal assets 
near the Gallup refinery and determined that the assets were abandoned, resulting in an impairment charge 
of  $67  million.  Following  this  conclusion,  we  revised  the  estimate  of  the  salvage  value  for  the  Gallup 
refinery asset group resulting in an additional $44 million impairment charge. These charges are included in 
impairment expense on our consolidated statements of income.

The determinations of expected future cash flows and the salvage values of refineries, as described earlier, 
require  considerable  judgment  and  are  sensitive  to  changes  in  underlying  assumptions  and  factors.  As  a 
result, there can be no assurance that the estimates and assumptions made for purposes of our impairment 
analysis will prove to be an accurate prediction of the future. Should our assumptions significantly change 
in future periods, it is possible we may determine the carrying values of certain of our refinery asset groups 
exceed the undiscounted estimated pretax cash flows of their refinery asset groups, which would result in 
future impairment charges.

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

114

on  applying  the  multi-period  excess  earnings  method,  which  is  an  income  approach.  Key  assumptions 
included management’s best estimates of the expected future cash flows from existing customers, customer 
attrition  rates  and  the  discount  rate.  Fair  value  determinations  require  considerable  judgment  and  are 
sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the 
estimates  and  assumptions  made  for  purposes  of  the  impairment  analysis  will  prove  to  be  an  accurate 
prediction  of  the  future.  The  fair  value  measurements  for  the  asset  group  fair  values  represent  Level  3 
measurements.

8. ACQUISITIONS 

Acquisition of Andeavor

On  October  1,  2018,  we  acquired  Andeavor.  Under  the  terms  of  the  merger  agreement,  Andeavor 
stockholders had the option to choose 1.87 shares of MPC common stock or $152.27 in cash per share of 
Andeavor  common  stock.  The  merger  agreement  included  election  proration  provisions  that  resulted  in 
approximately 22.9 million shares of Andeavor common stock being converted into cash consideration and 
the remaining 128.2 million shares of Andeavor common stock being converted into stock consideration. 
Andeavor  stockholders  received  in  the  aggregate  approximately  239.8  million  shares  of  MPC  common 
stock and approximately $3.5 billion in cash in connection with the Andeavor acquisition. The fair value of 
the MPC shares issued was determined on the basis of the closing market price of MPC’s common shares 
on the acquisition date. The cash portion of the purchase price was funded using cash on hand.

At  the  time  of  the  acquisition,  all  Andeavor  equity  awards,  with  the  exception  of  non-employee  director 
units, were converted to MPC equity awards. The converted equity awards continue to be governed by the 
same  terms  and  conditions  as  were  applicable  to  such  Andeavor  equity  awards  immediately  prior  to  the 
acquisition. We recognized $203 million of purchase consideration to reflect the portion of the fair value of 
the  time-based  converted  equity  awards  attributable  to  pre-combination  service  completed  by  the  award 
holders.  The  non-employee  director  units  were  accelerated  in  full  and  cancelled  and  the  holders  of  such 
units received an amount of cash equal to the number of shares of Andeavor common stock subject to such 
non-employee director units multiplied by the cash consideration per share.

Our financial results reflect the results of Andeavor from October 1, 2018, the date of the acquisition.

The components of the fair value of consideration transferred are as follows:

The purchase consideration allocation resulted in the recognition of $17.3 billion in goodwill, of which $1.0 
billion  is  tax  deductible  due  to  a  carryover  basis  from  Andeavor.  Our  Refining  &  Marketing,  Midstream 
and former Retail segment recognized $5.2 billion, $8.1 billion and $3.9 billion of 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.  See  Note  7  for  information  regarding 
impairments recorded in 2020 and 2019.

We  recognized  $47  million  in  acquisition  costs.  Additionally,  we  recognized  various  other  transaction-
related costs, including employee-related costs associated with the Andeavor acquisition. All of these costs 
are reflected in selling, general and administrative expenses. The employee-related costs are primarily due 
to  pre-existing  Andeavor  change  in  control  and  equity  award  agreements  that  create  obligations  and 
accelerated equity vesting upon MPC notifying employees of significant changes to or elimination of their 
responsibilities.

Andeavor’s results have been included in MPC’s financial statements for the period subsequent to the date 
of  the  acquisition  on  October  1,  2018.  Andeavor  contributed  revenues  of  approximately  $11.3  billion 
including  Speedway  for  the  period  from  October  1  through  December  31,  2018.  We  do  not  believe  it  is 

115

 
 
 
practical  to  disclose  Andeavor’s  contribution  to  earnings  for  the  period  from  October  1,  2018  through 
December  31,  2018  as  our  integration  efforts  have  resulted  in  the  elimination  of  Andeavor  stand-alone 
discrete financial information due mainly to our inclusion of Andeavor inventory in our consolidated LIFO 
inventory  pools,  which  does  not  allow  us  to  objectively  distinguish  the  cost  of  sales  between  the  two 
historical reporting entities.

Acquisition of Terminal and Retail Locations in New York

During the third quarter of 2019, we acquired a 900,000-barrel capacity light product and asphalt terminal 
and  33  NOCO  Express  retail  stores  in  Buffalo,  Syracuse  and  Rochester,  New  York,  from  NOCO 
Incorporated for total consideration of $135 million. 

Based on the final fair value estimates of assets acquired and liabilities assumed at the acquisition date, $38 
million of the purchase price was allocated to property, plant and equipment, $3 million to inventory and 
$94  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. The terminal is accounted for 
within the Refining & Marketing segment and the retail stores were accounted for within our former Retail 
segment.

The  amount  of  revenue  and  income  from  operations  associated  with  the  acquisition  from  the  acquisition 
date  to  December  31,  2019  did  not  have  a  material  impact  on  the  consolidated  financial  statements.  In 
addition,  assuming  the  acquisition  had  occurred  on  January  1,  2018,  the  consolidated  pro  forma  results 
would not have been materially different from the reported results.

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 operate 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. 

The  amount  of  revenue  and  income  from  operations  associated  with  the  acquisition  from  the  acquisition 
date  to  December  31,  2018  did  not  have  a  material  impact  on  the  consolidated  financial  statements.  In 
addition,  assuming  the  acquisition  had  occurred  on  January  1,  2017,  the  consolidated  pro  forma  results 
would not have been materially different from the reported results.

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  our  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. 

The  amount  of  revenue  and  income  from  operations  associated  with  the  acquisition  from  the  terminal 
acquisition  date  to  December  31,  2018  did  not  have  a  material  impact  on  the  consolidated  financial 
statements.  In  addition,  assuming  the  terminal  acquisition  had  occurred  on  January  1,  2017,  the 
consolidated pro forma results would not have been materially different from the reported results.

9.  VARIABLE INTEREST ENTITIES 

Consolidated VIE

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

The creditors of MPLX do not have recourse to MPC’s general credit through guarantees or other financial 
arrangements,  except  as  noted.  MPC  has  effectively  guaranteed  certain  indebtedness  of  LOOP  LLC 
(“LOOP”)  and  LOCAP  LLC  (“LOCAP”),  in  which  MPLX  holds  an  interest.  See  Note  29  for  more 
information. The assets of MPLX can only be used to settle its own obligations and its creditors have no 
recourse to our assets, except as noted earlier.

In May 2016, Crowley Coastal Partners LLC (“Crowley Coastal Partners”) was formed to own an interest 
in both Crowley Ocean Partners LLC (“Crowley Ocean Partners”) and Crowley Blue Water Partners LLC 
(“Crowley Blue Water Partners”). We have determined that Crowley Coastal Partners is a VIE based on the 
terms of the existing financing arrangements for Crowley Blue Water Partners and Crowley Ocean Partners 
and the associated debt guarantees by MPC and Crowley. Our maximum exposure to loss at December 31, 
2020 was $424 million, which includes our equity method investment in Crowley Coastal Partners and the 
debt  guarantees  provided  to  each  of  the  lenders  to  Crowley  Blue  Water  Partners  and  Crowley  Ocean 
Partners. We are not the primary beneficiary of this VIE because we do not have the ability to control the 
activities that significantly influence the economic outcomes of the entity and, therefore, do not consolidate 
the entity.

MPLX VIEs

For those entities that have been deemed to be VIEs, neither MPLX nor any of its subsidiaries have been 
deemed to be the primary beneficiary due to voting rights on significant matters. While we have the ability 
to  exercise  influence  through  participation  in  the  management  committees  which  make  all  significant 
decisions,  we  have  equal  influence  over  each  committee  as  a  joint  interest  partner  and  all  significant 
decisions require the consent of the other investors without regard to economic interest and as such we have 
determined that these entities should not be consolidated and apply the equity method of accounting with 
respect to our investments in each entity.

Sherwood Midstream has been deemed the primary beneficiary of Sherwood Midstream Holdings due to its 
controlling  financial  interest  through  its  authority  to  manage  the  joint  venture.  As  a  result,  Sherwood 
Midstream consolidates Sherwood Midstream Holdings.

MPLX’s maximum exposure to loss as a result of its involvement with equity method investments includes 
its equity investment, any additional capital contribution commitments and any operating expenses incurred 
by  the  subsidiary  operator  in  excess  of  its  compensation  received  for  the  performance  of  the  operating 
services. 

We account for our ownership interest in each of these investments as an equity method investment. See 
Note 17 for ownership percentages and investment balances related to our non-consolidated VIEs.

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

11.  EARNINGS PER SHARE 

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

As  of  December  31,  2020,  we  had  $2.96  billion  of  remaining  share  repurchase  authorizations  from  our 
board  of  directors.  We  may  utilize  various  methods  to  effect  the  repurchases,  which  could  include  open 
market  repurchases,  negotiated  block  transactions,  tender  offers,  accelerated  share  repurchases  or  open 
market solicitations for shares, some of which may be effected through Rule 10b5-1 plans. The timing and 
amount of future repurchases will depend upon several factors, including market and business conditions, 
and such repurchases may be initiated, suspended or discontinued at any time.

13.  SEGMENT INFORMATION 

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

•

•

•

•

•

Speedway’s  results  are  presented  separately  as  discontinued  operations.  See  Note  5  for  related 
disclosures.

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

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

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

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

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

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

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

On October 1, 2018, we acquired Andeavor and its results are included in each of our segments from the 
date of the acquisition. Also, on February 1, 2018, we contributed certain refining logistics assets and fuels 
distribution services to MPLX. The results of these new businesses are reported in the Midstream segment 
prospectively from February 1, 2018, resulting in a net reduction to Refining & Marketing segment results 
and a net increase to Midstream segment results of the same amount. No effect was given to prior periods 
as these entities were not considered businesses prior to February 1, 2018.

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

Corporate  consists  primarily  of  MPC’s  corporate  administrative  expenses  and  costs  related  to  certain  non-operating  assets, 
except for corporate overhead expenses attributable to MPLX, which are included in the Midstream segment. Corporate includes 
corporate costs of $26 million, $28 million and $26 million for 2020, 2019 and 2018, respectively, that are no longer allocable to 
Speedway under discontinued operations accounting.

2020 reflects impairments of goodwill, equity method investments and long lived assets. 2019 reflects impairments of goodwill 
and  equity  method  investments.  See  Note  7.  2018  includes  MPC’s  share  of  gains  from  the  sale  of  assets  remaining  from  the 
Sandpiper pipeline project, which was cancelled and impaired in 2016.

See Note 4.

2020 and 2019 includes costs incurred in connection with the Midstream strategic review and other related efforts. Both 2019 
and  2018  include  employee  severance,  retention  and  other  costs  related  to  the  acquisition  of  Andeavor.  Effective  October  1, 
2019, we have discontinued reporting Andeavor transaction-related costs as one year has passed since the acquisition and these 
costs  are  immaterial.  Costs  incurred  in  connection  with  the  Speedway  separation  are  included  in  discontinued  operations.  See 
Note 5. 

Includes gains related to The Andersons Marathon Holdings LLC and Capline Pipeline Company LLC. See Note 17.

Since we will continue to supply fuel to Speedway following its disposition, we have reported intersegment 
sales  to  Speedway,  that  were  previously  eliminated  in  consolidation,  as  third  party  sales  in  all  periods 
presented. Sales to Speedway from the Refining & Marketing segment represented 11 percent, 12 percent 
and  13  percent  of  our  total  annual  revenues  for  the  years  ended  December  31,  2020,  2019  and  2018, 
respectively. See Note 23 for the disaggregation of our revenue by segment and product line.

We  do  not  have  significant  operations  in  foreign  countries.  Therefore,  revenues  in  foreign  countries  and 
long-lived assets located in foreign countries, including property, plant and equipment and investments, are 
not material to our operations.

15.  INCOME TAXES 

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted 
by Congress and signed into law by President Trump in response to the COVID-19 pandemic. The CARES 
Act  contained  a  net  operating  loss  (“NOL”)  carryback  provision,  which  allowed  MPC  to  carryback  our 
2020  taxable  loss  to  2015  and  later  years.  The  five-year  NOL  carryback  is  available  for  all  businesses 
producing taxable losses in 2018 through 2020. Based on the NOL carryback, as provided by the CARES 
Act, we recorded an income tax receivable of $2.1 billion in other current assets to reflect our estimate of 
the tax refund we expect to receive from our 2020 federal tax return. The refund is expected to be received 
during the second half of 2021.

In the absence of the CARES Act NOL legislation, businesses would account for taxable losses as deferred 
tax assets and could realize the deferred tax asset by offsetting the losses against taxable income earned in 
future periods. Due to the corporate tax rate change from 35 percent to the current 21 percent under the Tax 
Cut and Jobs Act of 2017, taxpayers may recover taxes paid in tax years before 2018 at a 35 percent federal 
income  tax  rate.  The  limitation  on  the  percentage  of  taxable  income  that  may  be  offset  by  the  NOL, 
formerly 80 percent of income, was eliminated for years beginning before 2021.

The provision (benefit) for income taxes from continuing operations consisted of:

The deferred income tax assets and liabilities associated with discontinued operations remain in our balance sheet rather than 
being included in the carrying amount of assets and liabilities that are held for sale, as the sale is structured as a sale of assets.  
These discontinued operations deferred income tax assets and liabilities will be realized upon the sale of Speedway. 

At  December  31,  2020  and  2019,  federal  operating  loss  carryforwards  were  $4  million  and  $7  million, 
respectively, which includes a mix of indefinite carryforward ability and expiration periods ranging from 
2022 through 2037. As of December 31, 2020 and 2019, state and local operating loss carryforwards were 
$228  million  and  $11  million,  respectively,  which  includes  a  mix  of  indefinite  carryforward  ability  and 
expiration periods ranging from 2021 through 2042.

As  of  December  31,  2020  and  2019,  $11  million  of  valuation  allowances  have  been  recorded  related  to 
income  taxes.  A  federal  valuation  allowance  was  established  for  December  31,  2020  and  2019,  of 
$2  million,  primarily  due  to  the  expected  realizability  of  foreign  tax  credits.  A  state  and  local  valuation 
allowance  was  established  as  of  December  31,  2020  and  2019,  of  $9  million,  based  on  expected 
realizability of state and local tax operating losses. 

MPC  is  continuously  undergoing  examination  of  its  U.S.  federal  income  tax  returns  by  the  Internal 
Revenue  Service  (“IRS”).  Since  2012,  we  have  continued  to  participate  in  the  Compliance  Assurance 
Process  (“CAP”).  CAP  is  a  real-time  audit  of  the  U.S.  Federal  income  tax  return  that  allows  the  IRS, 
working in conjunction with MPC, to determine tax return compliance with the U.S. Federal tax law prior 
to filing the return. This program provides us with greater certainty about our tax liability for years under 
examination by the IRS. While Andeavor also underwent continual IRS examination, it did not participate 
in the CAP for tax periods prior to October 1, 2018.

Andeavor  and  its  subsidiaries’  IRS  audits  have  been  completed  through  the  2015  tax  year.  We  believe 
adequate provisions have been established for potential tax in periods not closed to examination. Further, 
we are routinely involved in U.S. state income tax audits. We believe all other audits will be resolved with 
the amounts provided for these liabilities. As of December 31, 2020, our federal income tax returns remain 
subject to examination for years 2016 through 2019. As of December 31, 2020, we have various state and 
local income tax returns subject to examination for years 2006 through 2019, depending on jurisdiction. 

The following table summarizes the activity in unrecognized tax benefits:

If the unrecognized tax benefits as of December 31, 2020 were recognized, $14 million would affect our 
effective  income  tax  rate.  There  were  $9  million  of  uncertain  tax  positions  as  of  December  31,  2020  for 
which it is reasonably possible that the amount of unrecognized tax benefits would significantly decrease 
during the next twelve months. For tax years 2009 and 2010, Andeavor had asserted a federal income tax 
claim for $159 million from the income tax effect of the receipt of the ethanol blender’s excise tax credit, 
for  which  the  tax  benefit  was  not  recorded.  The  statute  of  limitations  for  the  IRS  appeal  process  expired 
during the fourth quarter 2019 since the ability to obtain a refund was remote.

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 29 for indemnification information.

Interest and penalties related to income taxes are recorded as part of the provision for income taxes. Such 
interest  and  penalties  were  net  expenses  (benefits)  of  $(19)  million,  $(2)  million  and  $1  million  in  2020, 
2019 and 2018, respectively. As of December 31, 2020 and 2019, $(5) million and $7 million of interest 
and penalties were accrued related to income taxes.

The LIFO method accounted for 88 percent and 90 percent of total inventory value at December 31, 2020 
and 2019, respectively. There was no excess of replacement or current cost over our stated LIFO cost as of 
December 31, 2020. Current acquisition costs were estimated to exceed the LIFO inventory value by $787 
million at December 31, 2019

The cost of inventories of crude oil and refined products is determined primarily under the LIFO method. 
During 2020, we recorded a $561 million charge to reflect LIFO liquidations for our crude oil and refined 
product  inventories.  The  costs  of  inventories  in  the  historical  LIFO  layers  which  were  liquidated  were 
higher than current costs, which resulted in the charge to cost of revenues. There were no liquidations of 
LIFO inventories in 2019 and 2018. .

17.  EQUITY METHOD INVESTMENTS 

The Andersons Marathon Holdings LLC

Effective  October  1,  2019,  The  Andersons,  Inc.  and  MPC  contributed  jointly  owned  equity  interests  in 
three  ethanol  entities  into  a  new  legal  entity,  The  Andersons  Marathon  Holdings  LLC  (“TAMH”). 
Concurrently,  The  Andersons,  Inc.  contributed  a  wholly-owned  ethanol  facility  to  TAMH.  In  accordance 
with ASC 845, we derecognized the historical cost of our equity method investments in the legacy entities 
amounting to $123 million and recognized the new equity method investment in TAMH at fair value. We 
used  a  combination  of  market,  income  and  cost  approaches  to  determine  the  fair  value  of  our  ownership 
interest in TAMH with more reliance on the market and income approaches. The estimated cash flows used 
in the income approach were discounted using a weighted average cost of capital estimate and the market 
approach  utilized  EBITDA  and  capacity  multiples  for  similar  companies  and  transactions.  This  is  a 
nonrecurring fair value measurement and is recognized in Level 3 of the fair value hierarchy. We estimated 
the fair value of our ownership interest to be $175 million. The excess of the estimated fair value of our 
ownership interest over the carrying value of the derecognized net assets resulted in a $52 million non-cash 
net  gain  recorded  as  a  net  gain  on  disposal  of  assets  in  the  accompanying  consolidated  statements  of 
income. 

Capline LLC

During the three months ended March 31, 2019, we executed agreements with Capline Pipeline Company 
LLC  (“Capline  LLC”)  to  contribute  our  33  percent  undivided  interest  in  the  Capline  pipeline  system  in 
exchange  for  a  33  percent  ownership  interest  in  Capline  LLC.  In  connection  with  our  execution  of  these 
agreements, Capline LLC initiated a binding open season for southbound service from Patoka, Illinois to St. 
James,  Louisiana  or  Liberty,  Mississippi  with  an  additional  origination  point  at  Cushing,  Oklahoma. 
Service from Cushing, Oklahoma is part of a joint tariff with Diamond pipeline. 

127

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

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

As of December 31, 2020, the carrying value of our equity method investments was $361 million higher 
than the underlying net assets of investees. This basis difference is being amortized into net income over 
the remaining estimated useful lives of the underlying net assets, except for $199 million of excess related 
to goodwill and other non-depreciable assets. 

Dividends and partnership distributions received from equity method investees (excluding distributions that 
represented a return of capital previously contributed) were $577 million, $569 million and $458 million in 
2020, 2019 and 2018.

Property, plant and equipment includes gross assets acquired under finance leases of $819 million and $740 
million at December 31, 2020 and 2019, respectively, with related amounts in accumulated depreciation of 
$272  million  and  $215  million  at  December  31,  2020  and  2019.  Property,  plant  and  equipment  includes 
construction in progress of $1.83 billion and $3.12 billion at December 31, 2020 and 2019, respectively, 
which primarily relates to capital projects at our refineries and midstream facilities.

19.  GOODWILL AND INTANGIBLES 

Goodwill

Management annually evaluates goodwill for impairment as of November 30, as well as whenever events 
or changes in circumstances indicate it is more likely than not that the fair value of a reporting unit with 
goodwill  is  less  than  its  carrying  amount.  In  2020  and  2019,  we  recorded  impairments  of  goodwill  as

Fair Values – Recurring

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

(a)

Represents  the  impact  of  netting  assets,  liabilities  and  cash  collateral  when  a  legal  right  of  offset  exists.  As  of December  31, 
2020, cash collateral of $11 million was netted with mark-to-market liabilities. As of December 31, 2019, cash collateral of $51 
million was netted with mark-to-market derivative liabilities.

(b) We have no derivative contracts which 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  include  embedded  derivatives  in  commodity  contracts.  The  embedded  derivative 
liability relates to a natural gas purchase agreement embedded in a keep‑whole processing agreement. The 
fair  value  calculation  for  these  Level  3  instruments  at  December  31,  2020  used  significant  unobservable 
inputs including: (1) NGL prices interpolated and extrapolated due to inactive markets ranging from $0.47 
to $1.09 per gallon with a weighted average of $0.59 per gallon and (2) the probability of renewal of 100 
percent for the first and second five-year term of the natural gas purchase agreement and the related keep-
whole  processing  agreement.  Increases  or  decreases  in  the  fractionation  spread  result  in  an  increase  or 
decrease in the fair value of the embedded derivative liability.

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

21. DERIVATIVES 

For  further  information  regarding  the  fair  value  measurement  of  derivative  instruments,  including  any 
effect of master netting agreements or collateral, see Note 20. See Note 2 for a discussion of the types of 
derivatives  we  use  and  the  reasons  for  them.  We  do  not  designate  any  of  our  commodity  derivative 
instruments as hedges for accounting purposes.

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

On April 27, 2020, we issued $2.5 billion aggregate principal amount of senior notes in a public offering, 
consisting of $1.25 billion aggregate principal amount of 4.500% unsecured senior notes due May 2023 and 
$1.25 billion aggregate principal amount of 4.700% unsecured senior notes due May 2025. MPC used the 
net proceeds from this offering to repay amounts outstanding under its five-year revolving credit facility.

On October 1, 2020, all of the $475 million outstanding aggregate principal amount of 5.375% senior notes 
due October 2022, including the portion of such notes for which Andeavor was the obligor, were redeemed 
at a price equal to par.

On November 15, 2020, all of the $650 million outstanding aggregate principal amount of 3.400% senior 
notes due December 2020 were redeemed at a price equal to par.

Interest  on  each  series  of  senior  notes  is  payable  semi-annually  in  arrears.  The  MPC  senior  notes  are 
unsecured and unsubordinated obligations of MPC and rank equally with all of MPC’s other existing and 
future unsecured and unsubordinated indebtedness. The MPC senior notes are non-recourse and structurally 
subordinated to the indebtedness of our subsidiaries, including the outstanding indebtedness of Andeavor, 
MPLX and ANDX. The Andeavor senior notes are unsecured, unsubordinated obligations of Andeavor and 
are non-recourse to MPC and any of MPC’s subsidiaries other than Andeavor.

MPLX Term Loan Facility

The $1.0 billion of outstanding borrowings under the MPLX term loan facility was repaid during 2020 with 
net proceeds from the issuance of MPLX senior notes discussed below.

On  August  18,  2020,  MPLX  issued  $3.0  billion  aggregate  principal  amount  of  senior  notes  in  a  public 
offering, consisting of $1.5 billion aggregate principal amount of 1.750% senior notes due March 2026 and 
$1.5 billion aggregate principal amount of 2.650% senior notes due August 2030. The net proceeds were 
used to repay $1.0 billion of outstanding borrowings under the MPLX term loan agreement, to repay the 
$1.0 billion aggregate principal amount of floating rate senior notes due September 2021, to redeem all of 
the  $300  million  aggregate  principal  amount  of  MPLX’s  6.250%  senior  notes  due  October  2022  and  to 
redeem the $450 million aggregate principal amount of 6.375% senior notes due May 2024, including the 
portion  of  such  notes  issued  by  ANDX.  The  remaining  net  proceeds  were  used  for  general  business 
purposes. 

On  December  29,  2020,  MPLX  announced  the  redemption  of  all  the  $750  million  outstanding  aggregate 
principal amount of 5.250% senior notes due January 2025, including the portion of such notes issued by 
ANDX.  The  notes  were  redeemed  on  January  15,  2021  at  a  price  equal  to  102.625%  of  the  principal 
amount. These notes are included in long-term debt due within one year in our consolidated balance sheet 
as of December 31, 2020.

2019 Activity

On September 9, 2019, MPLX issued $2.0 billion aggregate principal amount of floating rate senior notes 
in a public offering, consisting of $1.0 billion aggregate principal amount of notes due September 2021 and 
$1.0 billion aggregate principal amount of notes due September 2022. Net proceeds from the issuance of

the floating rate senior notes were used to repay MPLX’s existing indebtedness and/or for general business 
purposes. The interest rate applicable to the floating rate senior notes due September 2021 is LIBOR plus 
0.9% per annum while the interest rate applicable to the floating rate senior notes due September 2022 is 
LIBOR plus 1.1% per annum. Interest is payable in March, June, September and December, commencing 
on December 9, 2019. Both series of floating rate notes are callable, in whole or in part, at par plus accrued 
and unpaid interest at any time on or after September 10, 2020.

In connection with MPLX’s acquisition of ANDX on July 30, 2019, MPLX assumed ANDX’s outstanding 
senior  notes,  which  had  an  aggregate  principal  amount  of  $3.75  billion,  with  interest  rates  ranging  from 
3.500% to 6.375% and maturity dates ranging from 2019 to 2047. On September 23, 2019, approximately 
$3.06  billion  aggregate  principal  amount  of  ANDX’s  outstanding  senior  notes  were  exchanged  for  new 
unsecured senior notes issued by MPLX having the same maturity and interest rates as the ANDX senior 
notes  in  an  exchange  offer  and  consent  solicitation  undertaken  by  MPLX,  leaving  approximately  $690 
million aggregate principal of outstanding senior notes issued by ANDX. Of this, $500 million was related 
to the 5.500% unsecured senior notes due 2019. The principal amount of $500 million and accrued interest 
of $14 million was paid on October 15, 2019, which included interest through the payoff date.

Interest  on  each  series  of  MPLX  fixed  rate  senior  notes  is  payable  semi-annually  in  arrears.  The  MPLX 
senior  notes  are  unsecured,  unsubordinated  obligations  of  MPLX  and  are  non-recourse  to  MPC  and  its 
subsidiaries other than MPLX and MPLX GP LLC, as the general partner of MPLX except as otherwise 
noted.

MPC Revolving Credit Agreements

On  August  28,  2018,  in  connection  with  the  Andeavor  acquisition,  MPC  entered  into  a  credit  agreement 
with  a  syndicate  of  lenders  providing  for  a  $5.0  billion  five-year  revolving  credit  facility  that  expires  in 
2023. The five-year credit agreement became effective on October 1, 2018. 

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

On April 27, 2020, MPC entered into an additional 364-day revolving credit agreement that provides for a 
$1.0 billion unsecured revolving credit facility that matures in April 2021. In February 2021, we elected to 
terminate this credit agreement. This facility provided us with additional liquidity and financial flexibility 
during  the  then  ongoing  commodity  price  and  demand  downturn.  There  were  no  borrowings  under  this 
credit  facility,  and  we  determined  that  the  incremental  borrowing  capacity  of  the  facility  was  no  longer 
necessary. We do not intend to replace this facility. We incurred no early termination fees as a result of the 
early termination of this credit agreement. 

MPC has an option under its $5.0 billion five-year credit agreement to increase the aggregate commitments 
by  up  to  an  additional  $1.0  billion,  subject  to,  among  other  conditions,  the  consent  of  the  lenders  whose 
commitments  would  be  increased.  In  addition,  MPC  may  request  up  to  two  one-year  extensions  of  the 
maturity date of the five-year credit agreement subject to, among other conditions, the consent of lenders 
holding a majority of the commitments, provided that the commitments of any non-consenting lenders will 
terminate  on  the  then-effective  maturity  date.  The  five-year  credit  agreement  includes  sub-facilities  for 
swing-line loans of up to $250 million and letters of credit of up to $2.2 billion (which may be increased to 
up to $3.0 billion upon receipt of additional letter of credit issuing commitments).

Borrowings  under  the  MPC  credit  agreements  bear  interest,  at  our  election,  at  either  the  Adjusted  LIBO 
Rate or the Alternate Base Rate (both as defined in the MPC credit agreements), plus an applicable margin. 
We are charged various fees and expenses under the MPC credit agreements, including administrative agent 
fees, commitment fees on the unused portion of the commitments and fees related to issued and outstanding 
letters of credit. The applicable margins to the benchmark interest rates and the commitment fees payable 
under the MPC credit agreements fluctuate based on changes, if any, to our credit ratings.

The  MPC  credit  agreements  contain  certain  representations  and  warranties,  affirmative  and  restrictive 
covenants and events of default that we consider to be usual and customary for arrangements of this type, 
including  a  financial  covenant  that  requires  us  to  maintain  a  ratio  of  Consolidated  Net  Debt  to  Total 
Capitalization (each as defined in the MPC credit agreements) of no greater than 0.65 to 1.00 as of the last 
day of each fiscal quarter. The covenants also restrict, among other things, our ability and/or the ability of 
certain of our subsidiaries to incur debt, create liens on assets or enter into transactions with affiliates. As of 
December 31, 2020, we were in compliance with the covenants contained in the MPC credit agreements. 

Trade Receivables Securitization Facility 
The trade receivables facility consists of our wholly-owned subsidiaries selling or contributing on an on-
going  basis  all  of  their  trade  receivables,  together  with  all  related  security  and  interests  in  the  proceeds 
thereof,  without  recourse,  to  another  wholly-owned,  bankruptcy-remote  special  purpose  subsidiary,  MPC 
Trade  Receivables  Company  LLC  (“TRC”),  in  exchange  for  a  combination  of  cash,  equity  and/or 
borrowings  under  a  subordinated  note  issued  by  TRC.  TRC,  in  turn,  has  the  ability  to  sell  undivided 
ownership  interests  in  qualifying  trade  receivables,  together  with  all  related  security  and  interests  in  the 
proceeds  thereof,  without  recourse,  to  the  purchasing  group  in  exchange  for  cash  proceeds.  The  trade 
receivables facility also provides for the issuance of letters of credit up to $750 million, provided that the 
aggregate credit exposure of the purchasing group, including outstanding letters of credit, may not exceed 
the lesser of $750 million or the balance of qualifying trade receivables at any one time.

To the extent that TRC retains an ownership interest in the receivables it has purchased or received under 
the facility, such interest will be included in our consolidated financial statements solely as a result of the 
consolidation of the financial statements of TRC with those of MPC. The receivables sold or contributed to 
TRC  are  available  first  and  foremost  to  satisfy  claims  of  the  creditors  of  TRC  and  are  not  available  to 
satisfy  the  claims  of  creditors  of  MPC.  TRC  has  granted  a  security  interest  in  all  of  its  assets  to  the 
purchasing group to secure its obligations under the Receivables Purchase Agreement.

139

Proceeds  from  the  sale  of  undivided  percentage  ownership  interests  in  qualifying  receivables  under  the 
trade receivables facility are reflected as debt on our consolidated balance sheet. We remain responsible for 
servicing the receivables sold to the purchasing group. TRC pays floating-rate interest charges and usage 
fees  on  amounts  outstanding  under  the  trade  receivables  facility,  if  any,  unused  fees  on  the  portion  of 
unused commitments and certain other fees related to the administration of the facility and letters of credit 
that are issued and outstanding under the trade receivables facility. 

The receivables purchase agreement and receivables sale agreement contain representations and covenants 
that  we  consider  usual  and  customary  for  arrangements  of  this  type.  Trade  receivables  are  subject  to 
customary criteria, limits and reserves before being deemed to qualify for sale by TRC pursuant to the trade 
receivables facility. In addition, further purchases of qualified trade receivables under the trade receivables 
facility are subject to termination, and TRC may be subject to default fees, upon the occurrence of certain 
amortization events that are included in the receivables purchase agreement, all of which we consider to be 
usual and customary for arrangements of this type. As of December 31, 2020, we were in compliance with 
the covenants contained in the receivables purchase agreement and receivables sale agreement.

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 borrowings under the amended and restated MPLX $3.5 
billion bank revolving credit facility.

The MPLX credit agreement includes letter of credit issuing capacity of up to approximately $300 million 
and swingline loan capacity of up to $150 million. The revolving borrowing capacity may be increased by 
up to an additional $1.0 billion, subject to certain conditions, including the consent of the lenders whose 
commitments would increase. 

Borrowings  under  the  MPLX  credit  agreement  bear  interest,  at  MPLX’s  election,  at  the  Adjusted  LIBO 
Rate or the Alternate Base Rate (both as defined in the MPLX credit agreement) plus an applicable margin. 
MPLX  is  charged  various  fees  and  expenses  in  connection  with  the  agreement,  including  administrative 
agent fees, commitment fees on the unused portion of the commitments and fees with respect to issued and 
outstanding letters of credit. The applicable margins to the benchmark interest rates and the commitment 
fees  payable  under  the  MPLX  credit  agreement  fluctuate  based  on  changes,  if  any,  to  MPLX’s  credit 
ratings. 

The  MPLX  credit  agreement  contains  certain  representations  and  warranties,  affirmative  and  restrictive 
covenants and events of default that we consider to be usual and customary for an agreement of this type, 
including a financial covenant that requires MPLX to maintain a ratio of Consolidated Total Debt as of the 
end of each fiscal quarter to Consolidated EBITDA (both as defined in the MPLX credit agreement) for the 
prior four fiscal quarters of no greater than 5.0 to 1.0 (or 5.5 to 1.0 for up to two fiscal quarters following 
certain  acquisitions).  Consolidated  EBITDA  is  subject  to  adjustments  for  certain  acquisitions  completed 
and capital projects undertaken during the relevant period. The covenants also restrict, among other things, 
MPLX’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 December 31, 2020, MPLX was in compliance with the covenants 
contained in the MPLX credit agreement.

26.  PENSION AND OTHER POSTRETIREMENT BENEFITS 

We  have  noncontributory  defined  benefit  pension  plans  covering  substantially  all  employees.  Benefits 
under  these  plans  have  been  based  primarily  on  age,  years  of  service  and  final  average  pensionable 
earnings. The years of service component of these formulae was frozen as of December 31, 2009. Certain 
of  the  pensionable  earnings  components  were  frozen  as  of  December  31,  2012.  Benefits  for  service 
beginning January 1, 2010 and beginning on January 1, 2016 are based on a cash balance formula with an 
annual percentage of eligible pay credited based upon age and years of service or at a flat rate of eligible 
pay, depending on covered employee group. Substantially all of our employees also accrue benefits under a 
defined contribution plan.

We  also  have  other  postretirement  benefits  covering  most  employees.  Retiree  health  care  benefits  are 
provided  through  comprehensive  hospital,  surgical,  major  medical  benefit,  prescription  drug  and  related 
health  benefit  provisions  subject  to  various  cost  sharing  features.  Retiree  life  insurance  benefits  are 
provided to a closed group of retirees. Other postretirement benefits are not funded in advance. 

In  connection  with  the  Andeavor  acquisition,  we  assumed  a  number  of  additional  qualified  and 
nonqualified  noncontributory  benefit  pension  plans,  covering  substantially  all  former  Andeavor 
employees.  Benefits  under  these  plans  are  determined  based  on  final  average  compensation  and  years  of 
service  through  December  31,  2010  and  a  cash  balance  formula  for  service  beginning  January  1, 
2011. These plans were frozen as of December 31, 2018. Further, as of December 31, 2019, the qualified 
plans were merged with our existing qualified plans in which the actuarial assumptions were materially the 
same between the plans. We also assumed a number of additional postretirement benefits covering eligible 
employees. These benefits were merged with our existing benefits beginning January 1, 2019. 

Obligations and Funded Status 

The  accumulated  benefit  obligation  for  all  defined  benefit  pension  plans  was  $3,369  million  and  $3,013 
million as of December 31, 2020 and 2019.

The primary driver of the actuarial loss for the pension plans in 2020 and 2019 was the decrease in interest rates. The plans also 
saw moderate losses related to demographic experience in each year.

Amounts exclude those related to LOOP and Explorer, equity method investees with defined benefit pension and postretirement 
plans for which net losses of $16 million and less than $1 million were recorded in accumulated other comprehensive loss in 
2020, reflecting our ownership share.

Net periodic benefit cost reflects a calculated market-related value of plan assets which recognizes changes in fair value over 
three years.

For  certain  of  our  pension  plans,  lump  sum  payments  to  employees  retiring  in  2020,  2019  and  2018 
exceeded the plan’s total service and interest costs expected for those years. Settlement losses are required 
to  be  recorded  when  lump  sum  payments  exceed  total  service  and  interest  costs.  As  a  result,  pension 
settlement expenses were recorded in 2020, 2019 and 2018.

Expected Long-term Return on Plan Assets

The overall expected long-term return on plan assets assumption is determined based on an asset rate-of-
return modeling tool developed by a third-party investment group. The tool utilizes underlying assumptions 
based on actual returns by asset category and inflation and takes into account our asset allocation to derive 
an  expected  long-term  rate  of  return  on  those  assets.  Capital  market  assumptions  reflect  the  long-term 
capital  market  outlook.  The  assumptions  for  equity  and  fixed  income  investments  are  developed  using  a 
building-block approach, reflecting observable inflation information and interest rate information available 
in  the  fixed  income  markets.  Long-term  assumptions  for  other  asset  categories  are  based  on  historical 
results, current market characteristics and the professional judgment of our internal and external investment 
teams.

Plan Investment Policies and Strategies

The investment policies for our pension plan assets reflect the funded status of the plans and expectations 
regarding our future ability to make further contributions. Long-term investment goals are to: (1) manage 
the assets in accordance with the legal requirements of all applicable laws; (2) diversify plan investments 
across asset classes to achieve an optimal balance between risk and return and between income and growth 
of  assets  through  capital  appreciation;  and  (3)  source  benefit  payments  primarily  through  existing  plan 
assets and anticipated future returns.

The  investment  goals  are  implemented  to  manage  the  plans’  funded  status  volatility  and  minimize  future 
cash contributions. The asset allocation strategy will change over time in response to changes primarily in 
funded  status,  which  is  dictated  by  current  and  anticipated  market  conditions,  the  independent  actions  of 
our investment committee, required cash flows to and from the plans and other factors deemed appropriate. 
Such changes in asset allocation are intended to allocate additional assets to the fixed income asset class 
should the funded status improve. The fixed income asset class shall be invested in such a manner that its 
interest rate sensitivity correlates highly with that of the plans’ liabilities. Other asset classes are intended to 
provide  additional  return  with  associated  higher  levels  of  risk.  Investment  performance  and  risk  is 
measured and monitored on an ongoing basis through quarterly investment meetings and periodic asset and 
liability studies. At December 31, 2020, the primary plan’s targeted asset allocation was 50 percent equity, 
private equity, real estate, and timber securities and 50 percent fixed income securities.

Fair Value Measurements 

Plan  assets  are  measured  at  fair  value.  The  following  provides  a  description  of  the  valuation  techniques 
employed for each major plan asset category at December 31, 2020 and 2019.

Cash and cash equivalents 

Cash and cash equivalents include a collective fund serving as the investment vehicle for the cash reserves 
and cash held by third-party investment managers. The collective fund is valued at net asset value (“NAV”) 

147

 
 
on a scheduled basis using a cost approach, and is considered a Level 2 asset. Cash and cash equivalents 
held by third-party investment managers are valued using a cost approach and are considered Level 2.

Equity

Equity  investments  includes  common  stock,  mutual  and  pooled  funds.  Common  stock  investments  are 
valued  using  a  market  approach,  which  are  priced  daily  in  active  markets  and  are  considered  Level  1. 
Mutual and pooled equity funds are well diversified portfolios, representing a mix of strategies in domestic, 
international  and  emerging  market  strategies.  Mutual  funds  are  publicly  registered,  valued  at  NAV  on  a 
daily  basis  using  a  market  approach  and  are  considered  Level  1  assets.  Pooled  funds  are  valued  at  NAV 
using a market approach and are considered Level 2.

Fixed Income 

Fixed income investments include corporate bonds, U.S. dollar treasury bonds and municipal bonds. These 
securities  are  priced  on  observable  inputs  using  a  combination  of  market,  income  and  cost  approaches. 
These securities are considered Level 2 assets. Fixed income also includes a well diversified bond portfolio 
structured as a pooled fund. This fund is valued at NAV on a daily basis using a market approach and is 
considered  Level  2.  Other  investments  classified  as  Level  1  include  mutual  funds  that  are  publicly 
registered, valued at NAV on a daily basis using a market approach.

Private Equity 

Private  equity  investments  include  interests  in  limited  partnerships  which  are  valued  using  information 
provided  by  external  managers  for  each  individual  investment  held  in  the  fund.  These  holdings  are 
considered Level 3.

Real Estate 

Real estate investments consist of interests in limited partnerships. These holdings are either appraised or 
valued using the investment manager’s assessment of assets held. These holdings are considered Level 3.

Other 

Other investments include two limited liability companies (“LLCs”) with no public market. The LLCs were 
formed to acquire timberland in the northwest U.S. These holdings are either appraised or valued using the 
investment manager’s assessment of assets held. These holdings are considered Level 3. Other investments 
classified as Level 1 include publicly traded depository receipts.

Contributions to defined benefit plans 
Our funding policy with respect to the funded pension plans is to contribute amounts necessary to satisfy 
minimum  pension  funding  requirements,  including  requirements  of  the  Pension  Protection  Act  of  2006, 
plus such additional, discretionary, amounts from time to time as determined appropriate by management. 
In  2020,  we  made  contributions  totaling  $3  million  to  our  funded  pension  plans.  For  2021,  we  have 
$65 million of required funding, but we may also make voluntary contributions to our funded pension plans

Contributions to defined contribution plan 

We also contribute to a defined contribution plan for eligible employees. Contributions to this plan totaled 
$180 million, $181 million and $118 million in 2020, 2019 and 2018, respectively.

Multiemployer Pension Plan

We contribute to one multiemployer defined benefit pension plan under the terms of a collective-bargaining 
agreement  that  covers  some  of  our  union-represented  employees.  The  risks  of  participating  in  this 
multiemployer plan are different from single-employer plans in the following aspects:

•

•

•

Assets contributed to the multiemployer plan by one employer may be used to provide benefits 
to employees of other participating employers.

If a participating employer stops contributing to the plan, the unfunded obligations of the plan 
may be borne by the remaining participating employers.

If  we  choose  to  stop  participating  in  the  multiemployer  plan,  we  may  be  required  to  pay  that 
plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

Our participation in this plan for 2020, 2019 and 2018 is outlined in the table below. The “EIN” column 
provides  the  Employee  Identification  Number  for  the  plan.  The  most  recent  Pension  Protection  Act  zone 
status available in 2020 and 2019 is for the plan’s year ended December 31, 2019 and December 31, 2018, 
respectively. The zone status is based on information that we received from the plan and is certified by the 
plan’s actuary. Among other factors, plans in the red zone are generally less than 65 percent funded. The 
“FIP/RP  Status  Pending/Implemented”  column  indicates  a  financial  improvement  plan  or  a  rehabilitation 
plan has been implemented. The last column lists the expiration date of the collective-bargaining agreement 
to which the plan is subject. There have been no significant changes that affect the comparability of 2020, 
2019 and 2018 contributions. Our portion of the contributions does not make up more than five percent of 
total contributions to the plan.

27.  STOCK-BASED COMPENSATION 

Description of the Plans

Effective  April  26,  2012,  our  employees  and  non-employee  directors  became  eligible  to  receive  equity 
awards under the Amended and Restated Marathon Petroleum Corporation 2012 Incentive Compensation 
Plan  (“MPC  2012  Plan”).  The  MPC  2012  Plan  authorizes  the  Compensation  and  Organization 
Development Committee of our board of directors (“Committee”) to grant non-qualified or incentive stock 
options, stock appreciation rights, stock awards (including restricted stock and restricted stock unit awards), 
cash awards and performance awards to our employees and non-employee directors. Under the MPC 2012 
Plan, no more than 50 million shares of our common stock may be delivered and no more than 20 million 
shares of our common stock may be the subject of awards that are not stock options or stock appreciation 
rights. In the sole discretion of the Committee, 20 million shares of our common stock may be granted as 
incentive stock options. Shares issued as a result of awards granted under these plans are funded through 
the issuance of new MPC common shares.

Prior to April 26, 2012, our employees and non-employee directors were eligible to receive equity awards 
under the Marathon Petroleum Corporation 2011 Second Amended and Restated Incentive Compensation 
Plan (“MPC 2011 Plan”). 

In connection with the Andeavor acquisition in October of 2018, we converted the outstanding option and 
equity  incentive  awards  (other  than  awards  held  by  non-employee  directors  of  Andeavor,  which  awards 
were  paid  out  in  connection  with  the  acquisition)  under  the  Andeavor  plans  to  awards  that  provide  for 
rights to acquire (in the case of options) or be settled in or otherwise determined in reference to shares of 
MPC  common  stock  in  place  of  shares  of  Andeavor  common  stock  (in  the  case  of  equity  incentive 
awards). As part of that conversion, we used an exchange ratio for the respective share prices of Andeavor 
common stock and MPC common stock to ensure that the award holders’ economic opportunity remained 
constant,  and  for  converted  awards,  which  included  a  performance  component,  performance  was 
determined  at  the  time  of  the  conversion  and  the  awards  became  subject  to  a  time-based  vesting  only 
design. The converted awards otherwise continue to be subject to the terms and conditions of their award 
agreements and the applicable Andeavor plan under which such awards were granted. 

Stock-Based Awards under the Plans

We expense all share-based payments to employees and non-employee directors based on the grant date fair 
value of the awards over the requisite service period, adjusted for estimated forfeitures.

Stock Options 
We  grant  stock  options  to  certain  officer  and  non-officer  employees.  All  of  the  stock  options  granted  in 
2020  were  granted  under  the  MPC  2012  Plan.  Stock  options  awarded  under  the  MPC  2011  Plan  and  the 
MPC 2012 Plan represent the right to purchase shares of our common stock at its fair market value, which 
is the closing price of MPC’s common stock on the date of grant. Stock options have a maximum term of 
ten years from the date they are granted, and vest over a requisite service period of three years. We use the 
Black Scholes option-pricing model to estimate the fair value of stock options granted, which requires the 
input of subjective assumptions.

Restricted Stock and Restricted Stock Units 

We grant restricted stock and restricted stock units to employees and non-employee directors. In general, 
restricted stock and restricted stock units granted to employees vest over a requisite service period of three 
years. Restricted stock and restricted stock unit awards granted to officers are subject to an additional one 
year  holding  period  after  the  three-year  vesting  period.  Restricted  stock  recipients  have  the  right  to  vote 
such  stock;  however,  dividends  are  accrued  and  when  vested  are  payable  at  the  dates  specified  in  the 
awards.  The  non-vested  shares  are  not  transferable  and  are  held  by  our  transfer  agent.  The  fair  values  of 
restricted stock are equal to the market price of our common stock on the grant date. Restricted stock units 
granted  to  non-employee  directors  are  considered  to  vest  immediately  at  the  time  of  the  grant  for 
accounting purposes, as they are non-forfeitable, but are not issued until the director’s departure from the 
board  of  directors.  Restricted  stock  unit  recipients  do  not  have  the  right  to  vote  any  shares  of  stock  and 
accrue dividend equivalents which when vested are payable at the dates specified in the awards. 

151

Performance Units 

We grant performance unit awards to certain officer employees. Performance units are dollar denominated. 
The  target  value  of  all  performance  units  is  $1.00,  with  actual  payout  up  to  $2.00  per  unit  (up  to  200 
percent of target). Performance units issued under the MPC 2012 Plan have a 36-month requisite service 
period. The payout value of these awards will be determined by the relative ranking of the total shareholder 
return (“TSR”) of MPC common stock compared to the TSR of a select group of peer companies, as well as 
the Standard & Poor’s 500 Energy Index fund over an average of four measurement periods. These awards 
will  be  settled  25  percent  in  MPC  common  stock  and  75  percent  in  cash.  The  number  of  shares  actually 
distributed  will  be  determined  by  dividing  25  percent  of  the  final  payout  by  the  closing  price  of  MPC 
common  stock  on  the  day  the  Committee  certifies  the  final  TSR  rankings,  or  the  next  trading  day  if  the 
certification  is  made  outside  of  normal  trading  hours.  The  performance  units  paying  out  in  cash  are 
accounted for as liability awards and recorded at fair value with a mark-to-market adjustment made each 
quarter. The performance units that settle in shares are accounted for as equity awards and do not receive 
dividend equivalents.

The expected life of stock options granted is based on historical data and represents the period of time that 
options granted are expected to be held prior to exercise. The 2020 assumption for expected volatility of 
our stock price reflects a weighting of 50 percent of our common stock implied volatility and 50 percent of 
our common stock historical volatility. The risk-free interest rate for periods within the expected life of the 
option is based on the U.S. Treasury yield curve in effect at the time of the grant.

awards was $2 million, which is expected to be recognized over a weighted average period of 1.94 years.

Performance units to be settled in MPC shares have a grant date fair value calculated using a Monte Carlo 
valuation  model,  which  requires  the  input  of  subjective  assumptions.  The  following  table  provides  a 
summary of these assumptions:

The risk-free interest rate for the remaining performance period as of the grant date is based on the U.S. 
Treasury  yield  curve  in  effect  at  the  time  of  the  grant.  The  look-back  period  reflects  the  remaining 
performance period at the grant date. The assumption for the expected volatility of our stock price reflects 
the average MPC common stock historical volatility.

28.  LEASES  

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 58 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.

Under  ASC  842,  the  components  of  lease  cost  are  shown  below.  Lease  costs  for  operating  leases  are 
recognized on a straight line basis and are reflected in the income statement based on the leased asset’s use. 
Lease costs for finance leases are reflected in depreciation and amortization and in net interest and other 
financial costs.

MPLX has certain natural gas gathering, transportation and processing agreements in which it is considered 
to  be  the  lessor  under  several  operating  lease  arrangements  in  accordance  with  GAAP.  MPLX’s  primary 
natural gas lease operations relate to a natural gas gathering agreement in the Marcellus Shale 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 natural gas implicit leases relate to a natural gas processing agreement in the Marcellus Shale 
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  expires  during  2027  and  2023, 
respectively, and will continue thereafter on a year-to-year basis until terminated by either party.

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 MPLX elected 
the practical expedient to carry forward historical classification conclusions. If and when a modification of 
an existing agreement occurs and the agreement is required to assessed under ASC 842, MPLX assesses the 
amended agreement and makes a determination as to whether a reclassification of the lease is required.

Our  revenue  from  implicit  lease  arrangements,  excluding  executory  costs,  totaled  approximately  $273 
million and $254 million in 2020 and 2019, respectively. Under ASC 840, our revenue from implicit lease 
arrangements, excluding executory costs, totaled approximately $221 million in 2018. The following is a 
schedule of minimum future rentals on the non‑cancellable operating leases as of December 31, 2020:

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

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

We  are  involved  in  a  number  of  environmental  enforcement  matters  arising  in  the  ordinary  course  of 
business. While the outcome and impact 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.

Asset Retirement Obligations 
Our  short-term  asset  retirement  obligations  were  $14  million  and  $20  million  at  December  31,  2020  and 
2019,  respectively,  which  are  included  in  other  current  liabilities  in  our  consolidated  balance  sheets.  Our 
long-term asset retirement obligations were $183 million and $184 million at December 31, 2020 and 2019, 
respectively, which are included in deferred credits and other liabilities in our consolidated balance sheets. 

157

 
 
 
 
 
 
 
 
 
 
Other Legal Proceedings

In  early  July  2020,  MPLX  received  a  Notification  of  Trespass  Determination  from  the  Bureau  of  Indian 
Affairs (“BIA”) relating to a portion of the Tesoro High Plains Pipeline (“THPP”), which crosses the Fort 
Berthold Reservation in North Dakota. The notification covered the rights of way for 23 tracts of land and 
demanded the immediate cessation of pipeline operations. The notification also assessed trespass damages 
of approximately $187 million. MPLX appealed this determination, which triggered an automatic stay of 
the  requested  pipeline  shutdown  and  payment.  On  October  29,  the  Assistant  Secretary  -  Indian  Affairs 
issued  an  order  vacating  the  BIA’s  trespass  order  and  requiring  the  Regional  Director  for  the  BIA  Great 
Plains  Region  to  issue  a  new  decision  on  or  before  December  15  covering  all  34  tracts  at  issue.  On 
December 15, the Regional Director of the BIA issued a new trespass notice to THPP consistent with the 
Assistant  Secretary  of  Indian  Affairs  order  vacating  the  prior  trespass  order.  The  new  order  found  that 
THPP  was  in  trespass  and  assessed  trespass  damages  of  approximately  $4  million  (including  interest), 
which has been paid. The order also required THPP to immediately cease and desist use of the portion of 
the pipeline that crosses the property at issue. THPP has complied with the Regional Director’s December 
15, 2020 notice. On February 12, 2021, landowners filed suit in the U.S. District Court for the District of 
North Dakota, requesting, among other things, that decisions by the Assistant Secretary - Indian Affairs and 
the Interior Board of Indian Appeals be vacated as to the award of damages to plaintiffs. 

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

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

Guarantees 

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

Guarantees related to indebtedness of equity method investees 

LOOP and LOCAP
MPC and MPLX hold interests in an offshore oil port, LOOP, and MPLX holds an interest in a crude oil 
pipeline  system,  LOCAP.  Both  LOOP  and  LOCAP  have  secured  various  project  financings  with 
throughput  and  deficiency  agreements.  Under  the  agreements,  MPC,  as  a  shipper,  is  required  to  advance 
funds if the investees are unable to service their debt. Any such advances are considered prepayments of 
future  transportation  charges.  The  duration  of  the  agreements  varies  but  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 December 31, 2020.

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

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

158

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

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

Crowley Ocean Partners and Crowley Blue Water Partners
In connection with our 50 percent ownership in Crowley Ocean Partners, 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 December 31, 2020, our maximum 
potential undiscounted payments under this agreement for debt principal totaled $119 million.

In  connection  with  our  50  percent  indirect  interest  in  Crowley  Blue  Water  Partners,  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 December 31, 2020, our maximum potential undiscounted 
payments under this arrangement was $115 million.

Marathon Oil indemnifications 

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

Other guarantees 

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

General guarantees associated with dispositions 
Over  the  years,  we  have  sold  various  assets  in  the  normal  course  of  our  business.  Certain  of  the  related 
agreements  contain  performance  and  general  guarantees,  including  guarantees  regarding  inaccuracies  in 
representations,  warranties,  covenants  and  agreements,  and  environmental  and  general  indemnifications 
that  require  us  to  perform  upon  the  occurrence  of  a  triggering  event  or  condition.  These  guarantees  and 

159

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  December  31,  2020  and  2019,  our  contractual  commitments  to  acquire  property,  plant  and  equipment 
and advance funds to equity method investees totaled $1.7 billion and $1.6 billion, respectively. 

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 if there are significant delays 
that are not due to force majeure.

SELECTED QUARTERLY FINANCIAL DATA (UNAUDITED)

As a result of the agreement to sell Speedway, Speedway’s results are reported separately as discontinued 
operations in our consolidated statements of income for all periods presented. 

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

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

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON 
ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. 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 Rule 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 
December 31, 2020, the end of the period covered by this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

During the quarter ended December 31, 2020, there were no changes in our internal control over financial 
reporting  that  have  materially  affected,  or  are  reasonably  likely  to  materially  affect,  our  internal  control 
over financial reporting.

ITEM 9B. OTHER INFORMATION 

On February 24, 2021, we provided notice to terminate our $1.0 billion 364-day revolving credit agreement 
(the “April 2020 MPC 364-Day Credit Agreement”), dated as of April 27, 2020, by and among MPC, as 
borrower,  the  banks  party  thereto  and  JPMorgan  Chase  Bank,  N.A.  as  administrative  agent,  which  was 
scheduled to expire on April 26, 2021. The material terms and conditions of the April 2020 MPC 364-Day 
Credit Agreement were described in our Current Report on Form 8-K filed on April 27, 2020 (the “Credit 
Agreement  Form  8-K”)  which  description  is  incorporated  by  reference  herein.  That  description  is  also 
qualified by reference to the full text of the April 2020 MPC 364-Day Credit Agreement, which is filed as 
Exhibit  10.1  to  the  Credit  Agreement  Form  8-K.  There  were  no  borrowings  under  the  credit  facility 
established under the April 2020 MPC 364-Day Credit Agreement, and we determined that the incremental 
borrowing capacity provided by the New MPC 364-Day Credit Agreement was no longer necessary. 

Certain  parties  to  the  New  MPC  364-Day  Revolving  Credit  Agreement  have  in  the  past  performed,  and 
may in the future from time to time perform, investment banking, financial advisory, lending or commercial 
banking  services  for  us  and  our  affiliates,  for  which  they  have  received,  and  may  in  the  future  receive, 
customary compensation and reimbursement of expenses.

2,892,592 restricted stock units granted pursuant to the MPC 2012 Plan and the MPC 2011 Plan for shares unissued and 
not  forfeited,  cancelled  or  expired  as  of  December  31,  2020.  The  amounts  in  column  (a)  do  not  include  (i)  709,416 
restricted stock units granted under the Andeavor Plans and not forfeited, cancelled or expired as of December 31, 2020, or 
(ii) 598,767 shares of restricted stock outstanding as of  December 31, 2020.

641,322  shares  as  the  maximum  potential  number  of  shares  that  could  be  issued  in  settlement  of  performance  units 
outstanding as of December 31, 2020 pursuant to the MPC 2012 Plan, based on the closing price of our common stock on 
December 31, 2020 of $41.36 per share. The number of shares reported for this award vehicle may overstate dilution. See 
Note 27 for more information on performance unit awards granted under the MPC 2012 Plan.

(b)

(c)

Restricted stock, restricted stock units and performance units are not taken into account in the weighted-average exercise price as 
such awards have no exercise price. 

Reflects the shares available for issuance pursuant to the MPC 2012 Plan. All granting authority under the MPC 2011 Plan was 
revoked  following  the  approval  of  the  MPC  2012  Plan  by  shareholders  on  April  25,  2012,  and  all  granting  power  under  the 
Andeavor Plans was revoked at the time of the Andeavor Merger. No more than 12,112,418 of the shares reported in this column 
may be issued for awards other than stock options or stock appreciation rights. The number of shares reported in this column 
assumes 641,322 as the maximum potential number of shares that could be issued pursuant to the MPC 2012 Plan in settlement 
of performance units outstanding as of December 31, 2020, based on the closing price of our common stock on December 31, 
2020, of $41.36 per share. The number of shares assumed for this award vehicle may understate the number of shares available 
for issuance pursuant to the MPC 2012 Plan. See Note 27 for more information on performance unit awards granted pursuant to 
the  MPC  2012  Plan.  Shares  related  to  grants  made  pursuant  to  the  MPC  2012  Plan  that  are  forfeited,  cancelled  or  expire 
unexercised become immediately available for issuance under the MPC 2012 Plan.

Book-entry Form of Stock Ownership  Marathon Petroleum Corporation exclusively  
maintains book-entry form of stockholder ownership. Account statements issued by  
stock transfer agent, Computershare, shall serve as stockholders’ record of ownership.  
Questions regarding stock ownership should be directed to Computershare.

Taxpayer Identification Number  Federal law requires that each stockholder provide  
a certified taxpayer identification number (TIN) for his/her stockholder account. For 
individual stockholders, your TIN is your Social Security number. If you do not provide  
a certified TIN, Computershare may be required to withhold 24% for federal income 
taxes from your dividends.

Address Change  It is important that you notify Computershare immediately, by phone, 
in writing or by fax, when you change your address. Seasonal addresses can be entered 
for your account.

Stock Return Performance Graph  The following performance graph compares the 
cumulative total return, assuming the reinvestment of dividends, of a $100 investment 
in our common stock from Dec. 31, 2015, to Dec. 31, 2020, compared to the cumulative 
total return of a $100 investment in the S&P 500 Index and an index of peer companies 
(selected by us) for the same period. Our peer group consists of the following companies 
that engage in domestic refining operations: BP plc, Chevron Corporation, Exxon Mobil 
Corporation, HollyFrontier Corporation, PBF Energy Inc., Phillips 66 and Valero Energy 
Corporation. 

The following performance graph is not “soliciting material” and will not be deemed  
to be filed with the Securities and Exchange Commission (SEC) or incorporated by  
reference into any of MPC’s filings with the SEC, except to the extent that we specifically 
incorporate it by reference into any such filings.

MARATHON PETROLEUM CORPORATION
539 SOUTH MAIN STREET
FINDLAY, OHIO 45840

Disclosures Regarding Forward-Looking Statements
This summary annual report wrap includes forward-looking statements. You can identify our forward-looking statements by words such as “anticipate,” 
“believe,” “commitment,” “could,” “design,” “estimate,” “expect,” “forecast,” “goal,” “guidance,” “imply,” “intend,” “may,” “objective,” “opportunity,” “outlook,” 
“plan,” “policy,” “position,” “potential,” “predict,” “principle,” “priority,” “project,” “proposition,” “prospective,” “pursue,” “seek,” “should,” “strategy,” “target,” 
“will,” “would,” or other similar expressions that convey the uncertainty of future events or outcomes. We have based our forward-looking statements on our  
current expectations, estimates and projections about our business and industry. We caution that these statements are not guarantees of future performance 
and you should not rely unduly on them, as they involve risks, uncertainties and assumptions that we cannot predict. In addition, we have based many of 
these forward-looking statements, including statements regarding the completion of our planned sale of Speedway and the expected benefits thereof, on 
assumptions about future events that may prove to be inaccurate. While our management considers these assumptions to be reasonable, they are inherently 
subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and 
many of which are beyond our control. Accordingly, our actual results may differ materially from the future performance that we have expressed or forecast 
in our forward-looking statements. In accordance with “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, we have included in 
our attached Form 10-K for the year ended Dec. 31, 2020, cautionary language identifying important factors, though not necessarily all such factors, that 
could cause actual results to differ materially from those set forth in the forward-looking statements.
