FROM THE PR ES IDENT  A N D   CE O

Fellow Shareholders,

Throughout a highly volatile year in global energy markets, Marathon Petroleum Corporation (MPC) 
demonstrated significant progress on our three strategic pillars, and we delivered on our commitments 
to performance, optimization and value creation. Executing on our operating, commercial and financial 
objectives, combined with a strong macro-economic environment, led to superior total shareholder 
returns in 2022 of 87%. At the same time, we continued to deepen our environmental, social and 
governance (ESG) efforts to drive long-term benefits for our business and stakeholders.

In 2022, we leveraged structural improvements we made in our commercial and operational execution 
to meet robust customer demand and capture strong margin opportunities. Our commitment to safe, 
reliable and environmentally sound operations enabled us to run our refining system at 96% utilization 
for the year, which included operating at full utilization in the second quarter, when demand for the 
transportation fuels we manufacture was highest. 

MPC generated $16.4 billion of cash from operations in 2022. We returned nearly $12 billion to 
shareholders through share repurchases during the year, bringing total repurchases between May 
2021 and the end of 2022 to almost $17 billion. Demonstrating our commitment to a secure, 
competitive and growing dividend, in November, we increased MPC’s quarterly dividend by 30%. 

Challenging ourselves to lead in sustainable energy, we made significant progress on our Martinez 
Renewables facility and further optimized our Dickinson Renewables facility; we added two substantial 
2030 goals to our emissions reduction targets; and we set a new industry record for the number 
of refineries certified for superior energy efficiency performance in one year through the U.S. 
Environmental Protection Agency’s (EPA) ENERGY STAR® program.

DEVELOPING ENDURING 
CAPABILITIES

In early 2020, we introduced our three 
strategic pillars: strengthening the 
competitive position of our assets, 
fostering a low-cost culture, and 
improving our commercial performance. 
Since then, they have become a 
foundational part of MPC’s DNA, aligning 
our efforts to increase profitability and 
drive long-term value creation.

We continue to be committed to these 
three strategic pillars today, because 
they address foundational aspects 
of our business that are within our 
control. While there is more to do, 
I am very proud of our progress in 
these areas, which was reflected in our 
2022 performance. We’ve achieved 
and sustained cost reductions while 
never compromising the safety of our 
employees or assets, made purposeful 
moves to strengthen our portfolio, 
and implemented commercial and 
operational improvements that can 
deliver incremental value into the future.

Importantly, while we’ve positioned 
ourselves for the future over the last 
few years, we’ve remained grounded in 
our Core Values, which guide us to hold 
steadfast in our commitment to safe and 
environmentally responsible operations, 
to find and create shared value, and to 
set and hold ourselves accountable to 
high expectations.

STRENGTHENING THE COMPETITIVE 
POSITION OF OUR ASSETS

In September, we completed the 
formation of our Martinez Renewables 
joint venture with Neste, which 
enhances the value of the project to 
convert our idled Martinez, California, 
refinery into a renewable fuels facility. 
The facility is expected to ramp up 
to produce 730 million gallons per year 
of renewable fuels by the end of 2023, 
with pretreatment capabilities expected 
to come online midyear 2023. At our 
Dickinson, North Dakota, renewable 
diesel facility, we optimized operations 
to accommodate more advantaged 
feedstocks, which lower the carbon 
intensity of the fuels we produce and 
further improve its economic potential.

M PC 2022 ANNUAL REPORT

In midstream, segment adjusted 
EBITDA grew 7% year over year, 
and the strength and stability of our 
logistics capabilities helped us navigate 
market fluctuations. MPLX advanced 
several organic growth projects in the 
Permian Basin and remained a source of 
growing distributions for MPC and other 
unitholders. In November, MPLX raised 
its quarterly distribution by 10%. At this 
current level, MPC is expected to receive 
approximately $2 billion of annual 
distributions from MPLX.

CONTINUED CAPITAL AND COST 
DISCIPLINE

Our success embedding a low-cost 
culture across the company enabled us 
to sustain our previously achieved $1.5 
billion of structural cost reduction. We 
remain focused on achieving operational 
excellence by reducing costs within our 
control, improving efficiency, driving 
operational improvements and being 
disciplined in capital allocation. We also 
worked hard to mitigate higher energy 
input costs throughout the year, and we 
believe our sustained, structural cost 
reductions help us to more readily adapt 
to market fluctuations.

We continue to build upon our Focus on 
Energy (FOE) program, which uses key 
performance indicators to guide energy 
management and promote energy 
efficiency across our refineries. In 2022, 
FOE-related initiatives led to more than 
$50 million in energy cost savings for 
the year, while avoiding 31,700 metric 
tons of carbon dioxide-equivalent 
emissions per month.

IMPROVING COMMERCIAL 
PERFORMANCE

Over the past 18 months, we have 
meaningfully changed our commercial 
approach across the company and 
strengthened our teams. To unlock 
value, we have empowered our people 
to optimize across our integrated 
system, more effectively leverage our 
scale and proximity to key supply 
sources and demand hubs, and improve 
product placement.

A near-term focus has been securing 
advantaged renewable feedstocks as we 
continue to advance our renewable fuels 

production capabilities. This includes 
exploring joint venture opportunities and 
strategic alliances within the renewable 
fuels value chain, as well as looking to 
expand upon the partnerships we’ve 
built with Neste and ADM.

In June, our Green Bison Soy 
Processing joint venture with ADM 
began construction of North Dakota’s 
first dedicated soybean processing 
plant. By the seasonal harvest of 2023, 
it is expected to begin supplying 
approximately 600 million pounds a 
year of locally advantaged, refined 
soybean oil exclusively to MPC, helping 
us further optimize feedstock sourcing 
for renewable diesel production at our 
Dickinson facility.

We continued to progress our Galveston 
Bay STAR project, which we expect to 
complete in the first quarter of 2023. 
The remaining scope of this strategic 
project is targeted to increase crude 
oil processing capacity by 40,000 
barrels per calendar day, improve 
residual upgrading capacity by 17,000 
barrels per calendar day, enhance diesel 
recovery, and enable the facility to 
process more advantaged crude oil.

OUR PATH TO LEADING IN 
SUSTAINABLE ENERGY

Across our integrated system, we are 
meeting the energy needs of today 
while investing in an energy-diverse 
future. Our approach to sustainability, 
which we apply across the components 
of ESG, is key to our success in this 
effort. We continue to focus on 
positioning MPC to lead in an energy-
diverse world by strengthening the 
resiliency of our business through 
reducing our carbon footprint and 
conserving natural resources; innovating 
for the future by investing in renewables 
and emerging technologies; and 
embedding sustainability in 
decision-making and in how we 
engage our stakeholders.

To help drive advancement, we have 
set meaningful targets to reduce 
greenhouse gas (GHG) emissions, 
methane emissions and freshwater 
intensity. We believe our continued 
progress demonstrates a tangible 

world’s need for reliable, affordable 
and responsibly produced energy. We 
anticipate that demand recovery for our 
products will continue and global supply 
constraints will persist in 2023. Our 
strategic pillars and financial priorities 
remain foundational, supporting our 
resiliency through near-term economic 
and geopolitical uncertainties. We will 
continue to focus our attention on how 
we run the business, always striving 
to be well-positioned to create value 
for our stakeholders regardless of the 
market’s tailwinds or turbulence.

Our goal is to position MPC as the 
refiner of choice, generating the most 
cash through cycle, and delivering 
superior returns to our shareholders, 
with our steadfast commitment to 
returning capital. 

Our achievements are a testament to 
the skills, dedication and adaptability 
of our people, who are enthusiastic 
about the opportunities ahead for our 
company. Our workforce demonstrated 
tremendous effort in 2022 – to meet 
demand for our products, to safely 
maintain and operate our assets and to 
support many value-creating programs 
and strategies that are critical for our 
long-term success. 

I am proud to lead MPC, and I am 
thankful and grateful for the work our 
people do each day to deliver value 
for our business and our shareholders. 
Thank you for supporting our company.

Sincerely, 

Michael J. Hennigan 
President and 
Chief Executive Officer

path to achieving these milestones. In 
2022, we established a goal to reduce 
our absolute Scope 3, category 11 
GHG emissions to 15% below 2019 
levels by 2030, becoming the first 
large downstream company to set 
an absolute Scope 3 target. We also 
expanded our existing goal for reducing 
methane emissions intensity across our 
natural gas gathering and processing 
business, creating a new long-range 
target of lowering intensity 75% from 
2016 levels by 2030.

Similarly, to ensure we have the 
diversity of thought necessary to 
shape our future, we continue to 
include a diversity, equity and inclusion 
(DE&I) component in the metrics 
that determine our annual bonus 
compensation. Established in 2021, we 
were the first U.S. independent refiner 
to link a DE&I metric to executive and 
employee compensation.

We also remain focused on being a 
good neighbor in our communities 
through meaningful relationships 
with key stakeholders to understand 
needs and concerns, define priorities 
and pursue shared goals. In 2022, the 
company invested more than $20 
million in the communities where we 
live and work as well as in the broader 
causes that united many of us, and our 
employees contributed more than 
$4 million in additional support.

We continue to allocate significant 
growth capital to low carbon projects, 
particularly around increasing our 
production of renewable fuels and 
natural gas. In fact, MPC is projected 
to become one of the largest global 
producers of renewable diesel in early 
2024, and MPLX assets currently 
process about 10% of the natural gas 
in the United States. MPC and MPLX 
are also actively involved in public-
private alliances to explore and develop 
pathways for emerging opportunities 
around carbon capture, utilization 
and sequestration (CCUS), as well 
as hydrogen energy production 
and utilization.

LOOKING FORWARD in 2023, 
I’m more optimistic than ever about 
MPC’s evolving role in meeting the

We are challenging ourselves to lead in sustainable energy by strengthening the resiliency of our operations, innovating 
for the future, and embedding sustainability in our decision-making and how we engage our people and many 
stakeholders. We apply this approach across environmental, social and governance (ESG) components as we execute 
our strategic priorities and view it as a key to our success.

One indication of our progress is recognition we have received from prominent ESG rating organizations.

STRENGTHENING R ESILIENCY

Over the past decade, and particularly over the past four years, we have diversified our portfolio and advanced a 
business model that supports the energy evolution and reductions in our overall carbon intensity. For example, when 
MPC formed in 2011, over 90% of our production was attributed to petroleum-based fuels. Since that time, we have 
diversified our business to include lower-carbon natural gas, renewable fuels, and petrochemical feedstocks, which 
now make up approximately 45% of our processed volumes.

For the third consecutive year, our energy efficiency performance earned 
MPC the ENERGY STAR® Partner of the Year – Sustained Excellence 
Award from the U.S. Environmental Protection Agency (EPA). MPC also 
set an industry record with six refineries receiving 2022 EPA ENERGY 
STAR certifications – the most refineries to ever earn this honor from the 
EPA in a single year.

INNOVATI NG FOR TH E FUTUR E

MPC is one of the largest marketers of renewable fuels in the U.S., and we continue to sharpen our focus on reducing 
the carbon intensity of our operations and the products we manufacture while enhancing business performance. 
This includes striving to increase our production and delivery of renewable fuels, seeking ways to expand the use of 
renewable energy in our operations, and deploying emerging technologies that reduce environmental impact.

In June 2022, we broke ground on the Green Bison Soy Processing facility, a joint 
venture project with ADM, and the first facility of its kind in North Dakota. When 
complete, the approximately $350 million complex will feature state-of-the-art 
automation technology with an anticipated processing capacity of 150,000 bushels 
of soybeans per day. By harvest 2023, the facility is expected to be producing 
approximately 600 million pounds of refined vegetable oil annually, which will be 
supplied exclusively to MPC as a feedstock for renewable diesel.

Aligned with our commitment to protect the health and safety 
of our people and our communities; responsibly manage our 
social impacts; promote diversity, equity and inclusion (DE&I); 
and maintain accountable and transparent governance, we are 
intentional about how we include and embrace sustainability in 
decision-making and engagement.

Engaged and Energized Workforce

For our people to thrive and to attract the most highly skilled 
and diverse employee base, we seek to advance an inclusive 
culture where everyone feels valued and confident to be 
themselves. Our employee networks are fundamental to 
achieving this goal.

More than 4,000 employees belong to our 69 employee 
network chapters across 16 states. Focused on seven 
populations — Asian, Black, Disability, Hispanic, LGBTQ+, 
Veterans and Women — these networks are led by 
employees with guidance and active involvement from 
executive leadership sponsors, and serve to connect 
colleagues across the company, provide opportunities for 
personal and professional development and help facilitate 
community involvement.

Guided by a dedicated team and supported by leadership 
companywide, MPC’s DE&I program is based on a four-pillar 
strategy of building awareness, increasing representation, 
ensuring success and applying measurement and 
accountability. To execute this strategy, in 2022 we focused 
on near-term action plans.

Stakeholder Engagement

Creating shared value with our range of stakeholders – our people, 
business partners, customers, communities, governments and 
shareholders – starts with working to understand their goals, 
perspectives and concerns and incorporating their feedback into our 
business strategies. We have several dedicated forums that help to 
facilitate internal and external engagement on a variety of topics, 
including Community Advisory Panels, a Tribal Affairs Working Group 
and site-specific Stakeholder Engagement Plans. As our business and 
stakeholder interests evolve, we continue to adapt and expand our 
approach to engagement.

We strategically focus our charitable community investments on 
three core areas: workforce development, sustainability and thriving 
communities. Engaging with stakeholders from different backgrounds 
helps us pursue projects that create a positive, measurable impact 
and build partnerships across diverse organizations. We encourage 
employees to support the causes and community efforts that are 
important to them by matching their donations to eligible organizations 
and funding volunteer incentive awards. In 2022, the company invested 
more than $20 million in the communities where we live and work 
as well as broader causes. Our employees contributed more than $4 
million in additional support. The company also raised more than $3.5 
million for charitable causes through fundraising events, many of which 
engaged our business partners, customers and suppliers.

Designated Environmental Incidents include 
three categories of environmental incidents: 
releases to the environment (air, land or water), 
environmental permit exceedances and agency 
enforcement actions.

Accountable and Transparent Governance

Our corporate impacts, risks and opportunities 
are identified and managed by company 
leadership with oversight from our Board. An 
additional layer of oversight exists with our 
Enterprise Risk Management Program. ESG is 
embedded across multiple Board committees 
to which MPC’s directors bring a range of 
backgrounds, critical skills, perspectives and 
expertise. As of year-end 2022, 10 of MPC’s 
11 directors were independent, as defined by 
New York Stock Exchange guidelines, with 
an independent chairman of the board. Each 
director attended 100% of board and committee 
meetings throughout the year. In January 2023, 
MPC announced a new independent board 
member, Toni Townes-Whitley.

As part of our broader commitment to transparent governance, we maintain regular dialogue with investor stewardship 
teams, and our ESG reporting and disclosures are aligned with TCFD, SASB, CDP and GRI Core.* We provide robust 
information on political engagement and lobbying through regular updates on our website. Additionally, MPC was the 
first independent U.S. downstream energy company to link a DE&I metric to compensation, and 20% of our annual 
cash bonus program is comprised of ESG metrics.

PART I

Item 1. Business

OVERVIEW

Marathon Petroleum Corporation (“MPC”) has 135 years of history in the energy business, and is a leading, integrated, 
downstream energy company. 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 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, including renewable 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, including renewable diesel, 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 and through long-term supply contracts with direct dealers who operate locations 
mainly under the ARCO® brand.

• Midstream – transports, stores, distributes and markets crude oil and refined products principally for the Refining & 
Marketing segment via refining logistics assets, pipelines, terminals, towboats and barges; gathers, processes and 
transports natural gas; and gathers, transports, fractionates, stores and markets NGLs. The Midstream segment 
primarily reflects the results of MPLX 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, 2022, we owned the general partner of MPLX and approximately 65 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.

On May 14, 2021, we completed the sale of Speedway, our company-owned and operated retail transportation fuel and 
convenience store business, to 7-Eleven, Inc. (“7-Eleven”) for cash proceeds of $21.38 billion ($17.22 billion after cash-tax 
payments). This transaction resulted in a pretax gain of $11.68 billion ($8.02 billion after income taxes), after deducting the book 
value of the net assets and certain other adjustments.

OUR OPERATIONS

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 2,898 mbpcd. During 2022, our refineries processed 2,761 mbpd of crude oil and 190 
mbpd of other charge and blendstocks. During 2021, our refineries processed 2,621 mbpd of crude oil and 178 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 

4

and asphalt. Additionally, we manufacture NGLs and petrochemicals and propane. See the Refined Product Marketing section 
for further information about the products we produce. 

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.

Gulf Coast Region (1,189 mbpcd)

Our Kenai refinery is located on the Cook Inlet, southwest of Anchorage. The Kenai refinery processes mainly Alaska domestic 
crude, domestic crude from North Dakota, along with limited international crude and manufactures distillates, gasoline, heavy 
fuel oil, asphalt, propane and NGLs and petrochemicals.

Planned maintenance activities, or turnarounds, requiring temporary shutdown of certain refinery operating units, are periodically 
performed at each refinery.

We obtain the crude oil we refine through negotiated term contracts and purchases or exchanges on the spot 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. The crude oil sourced outside of North America was acquired from various foreign national oil 
companies, production companies and trading companies.

Renewable Fuels 

The Dickinson, North Dakota, renewable fuels facility began operations at the end of 2020 and reached full design operating 
capacity in the second quarter of 2021. The facility has the capacity to produce 184 million gallons per year of renewable diesel 
from corn oil, soybean oil, fats and greases. The produced renewable diesel generates federal RINs and LCFS credits when sold 
in California or similar markets. These instruments are used to help meet our Renewable Fuel Standard and LCFS compliance 
obligations as a petroleum fuel producer.

On September 21, 2022, MPC closed on the formation of the Martinez Renewable Fuels joint venture (the “Martinez Renewable 
joint venture”), a partnership structured as a 50/50 joint venture with Neste Corporation (“Neste”). Converting the Martinez facility 
from refining petroleum to manufacturing renewable fuels signals our strong commitment to producing a substantial level of lower 
carbon-intensity fuels in California. The facility is expected to ramp up to producing 730 million gallons per year by the end of 
2023, with pretreatment capabilities coming online in 2023. 

Our wholly owned subsidiary, Virent Inc. (“Virent”), operates an advanced biofuels facility in Madison, Wisconsin at which it is 
working to commercialize a process for converting biobased feedstocks into renewable fuels and chemicals. During 2022, Virent 
continued to advance its technology to commercialization with demonstration activities in both the fuels and chemicals industries, 
including a demonstration flight with Gulfstream in a G650 aircraft in which one engine used 100 percent sustainable aviation fuel 
(“SAF”) that included Virent’s synthesized aromatic kerosene as a blending component to provide a 100 percent drop-in SAF that 
was fully compatible with today’s jet fuel specifications. Additional demonstration projects included the introduction of bio-based 
polyester fabrics to applications in the airline, fashion and outdoor clothing industries.

On December 14, 2021, we finalized the formation of a joint venture with Archer-Daniels-Midland Company (“ADM”) for the 
production of soybean oil to supply rapidly growing demand for renewable diesel fuel. The joint venture, which is named Green 
Bison Soy Processing, LLC, will own and operate a soybean processing complex in Spiritwood, North Dakota, with ADM owning 
75 percent of the joint venture and MPC owning 25 percent. When complete in 2023, the Spiritwood facility will source and 
process local soybeans and supply the resulting soybean oil exclusively to MPC. The Spiritwood complex is expected to produce 
approximately 600 million pounds of refined soybean oil annually, enough feedstock for approximately 75 million gallons of 
renewable diesel per year. 

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, Inc. (“The Andersons”).

Refined Product Sales

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, 2022, there were 7,209 brand jobber outlets in 
38 states, the District of Columbia and Mexico where independent entrepreneurs primarily maintain Marathon-branded outlets. 
We also have long-term supply contracts for 1,172 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 market area.

We sell gasoline, gasoline blendstocks and distillates (including No. 1 and No. 2 fuel oils, jet fuel, kerosene, diesel and 
renewable diesel) to wholesale customers, 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.

NGLs and Petrochemicals

We are a producer and marketer of NGLs and petrochemicals. Product availability varies by refinery and includes, among others, 
propylene, xylene, butane, benzene, toluene and cumene. 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, which is used to make carbon anodes for the aluminum smelting industry.

Asphalt

We have refinery-based asphalt production capacity of up to 141 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 industrial/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.

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 MEH 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  
crude oil, refined products and other pipelines. MPLX also owns and operates light products terminals, storage assets and 
maintains a fleet of owned and leased towboats and barges in support of fuels distribution on behalf of MPC. MPLX’s assets also 
include natural gas gathering systems and natural gas processing and NGL fractionation complexes. 

MPC-Retained Midstream Assets and Investments 

We own four Jones Act product tankers, have ownership interests in several crude oil and refined products pipeline systems and 
pipeline companies and have an indirect ownership interest in an ocean vessel joint venture through our investment in Crowley 
Coastal Partners LLC (“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 systems 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.

Rate Regulation

Some of our existing pipelines are considered interstate common carrier pipelines subject to regulation by the Federal Energy 
Regulatory Commission (“FERC”) under the Interstate Commerce Act (the “ICA”), Energy Policy Act of 1992 (“EPAct 1992”) and 
the rules and regulations promulgated under those laws. The ICA and FERC regulations require that tariff rates for oil pipelines, a 
category that includes crude oil and petroleum product pipelines, be just and reasonable and the terms and conditions of service 
must not be unduly discriminatory. The ICA permits interested persons to challenge newly proposed tariff rates or terms and 
conditions of service, or any change to tariff rates or terms and conditions of service, and authorizes FERC to suspend the 
effectiveness of such proposal or change for a period of time to investigate. If, upon completion of an investigation, FERC finds 
that the new or changed service or rate is unlawful, it is authorized to require the carrier to refund the revenues in excess of the 
prior tariff collected during the pendency of the investigation. An interested person may also challenge existing terms and 
conditions of service or rates and FERC may order a carrier to change its terms and conditions of service or rates prospectively. 
Upon an appropriate showing, a shipper may also obtain reparations, from a pipeline, for damages sustained as a result of rates 
or terms which FERC deemed were not just and reasonable. Such reparation damages may accrue from the complaint through 
the final order and during the two years prior to the filing of a complaint.

EPAct 1992 deemed certain interstate petroleum pipeline rates then in effect to be just and reasonable under the ICA. These 
rates are commonly referred to as “grandfathered rates.” Our rates for interstate transportation service in effect for the 365-day 
period ending on the date of the passage of EPAct 1992 were deemed just and reasonable and therefore are grandfathered. 
Subsequent changes to those rates are not grandfathered. New rates have since been established after EPAct 1992 for certain 
pipelines.

FERC permits regulated oil pipelines to change their rates within prescribed ceiling levels that are tied to an inflation index. A 
carrier must, as a general rule, utilize the indexing methodology to change its rates. Cost-of-service ratemaking, market-based 
rates and settlement rates are alternatives to the indexing approach and may be used in certain specified circumstances to 
change rates.

Air

GHG Emissions

We believe the advancement of public policy intended to address GHG 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 GHG emissions are in various phases of review, discussion or implementation. Reductions in GHG 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 GHG emissions programs, including acquiring emission credits 
or allotments.

In February 2021, the Interagency Working Group on the Social Cost of Greenhouse Gases published interim estimates of the 
social cost of carbon, methane and nitrous oxide (collectively, social cost of GHG emissions). In its proposed methane emission 
rules for the oil and natural gas sector, the EPA significantly increased the social cost of GHG emissions in the cost and benefit 
analysis for the proposed rule. A higher social cost could support more stringent GHG emission regulation in various rule 
makings from methane emissions to vehicle tailpipe emissions.

States are becoming active in regulating GHG emissions. These measures may include state actions to develop statewide or 
regional programs to report emissions and 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, California has enacted a cap-and-trade program. Much of the compliance costs associated 
with the California program 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 GHGs 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 2021, the EPA announced it is reconsidering the National Ambient Air Quality Standards (“NAAQS”) for ozone and fine 
particulate matter. In January 2023, EPA published its proposal to lower the primary (health-based) fine particulate matter annual 
standard from its current level of 12.0 µg/m3 to within the range of 9.0 to 10.0 µg/m3. EPA has not yet announced its decision on 
reconsideration of the ozone NAAQS. Lowering of the NAAQS and subsequent designation as a nonattainment area could result 
in increased costs associated with, or result in cancellation or delay of, capital projects at our or our customers’ facilities, or could 
require emission reductions that could result in increased costs to us or our customers. We cannot predict the effects of the 
various state implementation plan requirements at this time.

10

In California, the Governing Board for the South Coast Air Quality Management District (“SCAQMD”) adopted Rule 1109.1 in 
November 2021, which establishes Best Available Retrofit Control Technology (“BARCT”) oxides of nitrogen (“NOx”) and carbon 
monoxide (“CO”) emission limits for combustion equipment at petroleum refineries. These new requirements will replace the 
Regional Clean Air Incentives Market (“RECLAIM”) cap-and-trade program which has required a staged refinery-wide reduction 
of NOx emissions over the last several years and will result in additional emission reductions from our Los Angeles Refinery. 
Compliance with Rule 1109.1 is being phased in through 2032 and will 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, 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 to restore the regulatory text that existed prior to the 2015 Rule, effective December 23, 2019. The rule 
repealing the 2015 Rule has been challenged in multiple federal courts. On April 21, 2020, 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 vacated by 
a federal court. On December 7, 2021, EPA and the Army Corps issued a notice of proposed rulemaking with the stated purpose 
of repealing the 2020 Rule defining “waters of the United States” and adopting a rule largely based upon the definition adopted in 
1986 with some revisions based upon subsequent United States Supreme Court rulings, in particular Rapanos v. United States 
(2006) which produced two different tests for determining “waters of the United States,” the relatively permanent waters and 
significant nexus tests. A 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 Army Corps 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. A challenge of the 2021 authorization is currently pending before 
the U.S. District Court for the District of Columbia (“D.D.C.”), after being transferred from the U.S. District Court for the District of 
Montana in August 2022, and the plaintiffs request the court vacate and remand the 2021 authorization. Also, a petition has been 
filed with the Army Corps asking it to revoke the 2021 authorization. The Biden Administration could repeal or replace the 2021 
authorization in a subsequent rulemaking. The repeal, vacatur, revocation or replacement of the 2021 authorization could impact 
pipeline construction and 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 vapor and fire suppressant. At this time, AFFFs containing PFAS are the only 
proven foams that can prevent and control a flammable petroleum-based liquid fire involving a large storage tank or tank 
containment area.

In May 2016, EPA issued lifetime health advisory levels (“HALs”) and health effects support documents for two PFAS substances 
- Perfluorooctanoic Acid (“PFOA”) and Perfluorooctane Sulfonate (“PFOS”). These HALs were updated in June 2022, when EPA 
also issued HALs for two additional PFAS substances. In February 2019, EPA issued a PFAS Action Plan identifying actions it is 
planning to take to study and regulate various PFAS chemicals. 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. EPA did not issue any further regulations for PFAS under the Trump administration. In October 2021, EPA 
updated the 2019 PFAS Action Plan. On December 5, 2022, EPA issued to states and EPA regional offices a memorandum 
providing guidance for addressing PFAS discharges in wastewater and stormwater. Also, EPA has indicated it intends to issue a 
notice of proposed rulemaking in 2023 that will establish national drinking water standards for PFOS and PFOA. Congress may 
also take further action to regulate PFAS. We cannot currently predict the impact of potential statutes or regulations on our 
operations.

11

In addition, many states are actively proposing and adopting legislation and regulations relating to the use of AFFFs containing 
PFAS. Additionally, many states are using EPA HALs for PFOS and PFOA and some states are adopting and proposing state-
specific drinking water and cleanup standards for various PFAS, including but not limited to PFOS and PFOA. 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 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.

On September 6, 2022, EPA issued a notice of proposed rulemaking that would designate PFOS and PFOA as hazardous 
substances under CERCLA Section 102(a). Additional PFAS regulation could include the designation of PFAS as a RCRA 
hazardous waste. We cannot currently predict the impact of potential statutes or regulations on our remediation costs.

Vehicle and Fuel Requirements

Fuel Economy and GHG Emission Standards for Vehicles

The National Highway Traffic Safety Administration (“NHTSA”) establishes corporate average fuel economy (“CAFE”) standards 
for passenger cars and light trucks. In addition, EPA establishes carbon dioxide (“CO2”) emission standards for passenger cars 
and light trucks. At the direction of President Biden in his executive order setting a goal that 50 percent of all new passenger cars 
and light trucks sold in 2030 be zero emission vehicles, EPA and NHTSA have promulgated separate rules setting more stringent 
requirements for reductions through model year 2026. NHTSA’s amended CAFE standards would increase in stringency from 
model year 2023 levels by eight percent annually for model years 2024-2025 and ten percent annually for model year 2026. 
EPA’s revised model year 2023-2026 CO2 emission standards, which were finalized in December 2021, result in average fuel 
economy of 40 mpg in model year 2026. The NHTSA and EPA regulations have been challenged in court. Higher CAFE and CO2 
emission standards for cars and light trucks reduce demand for our transportation fuels. 

In addition, California may establish per its Clean Air Act waiver authority different standards that could apply in multiple states. 
EPA has issued a rule that reinstates California’s waiver for its Advanced Clean Car I program, which includes requirements for 
zero emission vehicle sales through 2025. California’s governor has also issued an executive order requiring sales of all new 
passenger vehicles in the state be zero-emission by 2035. The California Air Resources Board followed this executive order by 
finalizing its Advanced Clean Car II regulation, which bans the sale of internal combustion engine vehicles in California in 2035. 
Other states have issued, or may issue, zero emission vehicle mandates. 

Renewable Fuels Standards and Low Carbon Fuel Standards

Pursuant to the Energy Policy Act of 2005 and the EISA, Congress established a Renewable Fuel Standard (“RFS”) program that 
requires annual volumes of renewable fuel be blended into domestic transportation fuel. The statutory volumes apply through 
calendar year 2022. When EPA promulgates the annual renewable fuel volume obligations, EPA may reduce the statutory 
amount of renewable fuel that must be blended using its waiver or reset authority. After calendar year 2022, the statute gives 
EPA the authority to set the annual volumes. EPA has proposed annual volumes for 2023-2025 that increase the volume of 
renewable fuel that must be blended year over year. The greatest increase in annual volumes arises from EPA’s proposal to 
approve a process in which electricity generated from renewable biomass used to fuel vehicles can generate a Renewable 
Identification Number (“eRIN”) under the RFS. 

12

There is currently no regulatory method for verifying the validity of most 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 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. CARB is currently holding a series of workshops to 
discuss potential changes to the LCFS, including increasing the stringency of the carbon intensity targets for 2030 and beyond. 
We incur costs to comply with LCFS programs, 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 (“OSH Act”), 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 regulations promulgated pursuant to the OSH Act, including general industry 
standards, record-keeping requirements and monitoring of occupational exposure to regulated substances.

We are also subject at regulated facilities to the Occupational Safety and Health Administration’s Process Safety Management 
(“PSM”) and EPA’s Risk Management Program (“RMP”) requirements, which are intended to prevent or minimize the 
consequences of catastrophic releases of toxic, reactive, flammable or explosive chemicals. EPA has proposed revisions to its 
RMP regulation. The proposed revisions include a requirement that refineries with hydrofluoric acid alkylation units perform a 
safer technologies and alternatives analysis as part of the process hazard analysis and to document the feasibility of inherent 
safety measures. The application of these regulations can result in increased compliance expenditures.

In general, we expect industry and regulatory safety standards to become more stringent 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 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. 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 asset of strength, and our culture reflects the quality of individuals across our 
workforce. Our collaborative efforts, which include fostering an inclusive environment, providing broad-based development and 
mentorship opportunities, recognizing and rewarding accomplishments and offering benefits that support the well-being of our 
employees and their families, contribute to increased engagement and fulfilling careers. Empowering our people and prioritizing 

13

accountability are also key components for developing MPC’s high-performing culture, which is critical to achieving our strategic 
vision. 

Employee Profile

As of December 31, 2022, we employed approximately 17,800 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 3,755 
of our employees are covered by collective bargaining agreements. 

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 our Operational Excellence Management System, which expands on the 
RC14001® scope, incorporates a Plan-Do-Check-Act continual improvement cycle, and aligns with ISO 9001, incorporating 
quality and an increased stakeholder and process focus. 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 include several employee, process and environmental safety metrics.

In 2022, MPC rolled back a majority of its COVID protocols which included the return of all employees to their respective work 
locations. We continue to monitor the situation and adapt our COVID protocols as appropriate.

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 long-term incentive targets. Our annual bonus program is a critical 
component of our compensation, as it provides individual rewards for MPC’s achievement against preset financial and ESG 
goals, encouraging a sense of employee ownership. Employees in our senior leader pay grades, as well as most other leaders, 
receive long-term incentive awards annually to align their compensation to the interests of MPC shareholders and MPLX 
unitholders.

We offer comprehensive benefits that are also benchmarked annually, 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. In addition, we provide generous 
paid parental leave benefits for birth mothers and nonbirth parents; and parents who both work for the Company are each eligible 
for the benefit. Further, we have a substantial accrual cap for vacation banks and also award a significant number of college and 
trade school scholarships to high school senior children of our employees through the Marathon Petroleum Scholars Program. 
Both full-time and part-time employees are eligible for these benefits. 

Inclusion

Our company-wide Diversity, Equity and Inclusion ("DE&I") program is guided by a dedicated DE&I team led by our Vice 
President Talent Acquisition and Diversity, Equity & Inclusion and supported by leadership company-wide. Our program is based 
on our four-pillar DE&I strategy of building awareness, increasing representation, ensuring success, and measurement and 
accountability. To execute our strategy, our near-term action plans are focused on building a diverse workforce, creating a more 
inclusive culture, and contributing to our thriving communities.

We have employee networks focusing on seven populations: Asian, Black, Disability, Hispanic, LGBTQ+, Veterans and Women. 
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 

14

sponsors. The sponsors 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 DE&I strategy.

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. We have in the past 
been adversely affected by certain of, and may in the future be affected by, these risks. You should not interpret the disclosure of 
any risk factor to imply that the risk has not already materialized.

Business and Operational Risks

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 and other feedstocks. The prices of feedstocks and the prices at which we can sell our refined products 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 feedstocks and refined products; 

transportation infrastructure cost and availability;

operation levels of other refineries in our markets;

the development by competitors of new refining or renewable conversion capacity;

natural gas and electricity supply costs; 

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

local weather conditions; and

the occurrence of other risks described herein. 

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 generally 
purchase our 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.

17

Legal, technological, political and scientific developments regarding emissions, fuel efficiency and alternative fuel 
vehicles may decrease demand for petroleum-based transportation fuels. 

Developments aimed at reducing vehicle emissions, increasing vehicle efficiency or reducing the sale of new petroleum-fueled 
vehicles may decrease the demand and may increase the cost for our transportation fuels. At the direction of President Biden in 
his Executive Order setting a goal that 50 percent of all new passenger cars and light trucks sold in 2030 be zero emission 
vehicles, EPA and NHTSA have promulgated separate rules setting more stringent requirements for reductions through model 
year 2026. NHTSA’s amended CAFE standards increase in stringency from model year 2023 levels by eight percent annually for 
model years 2024-2025 and ten percent annually for model year 2026. EPA’s revised model year 2023-2026 CO2 emission 
standards, which were finalized in December 2021, result in average fuel economy of 40 mpg in model year 2026. Other 
jurisdictions have issued or considered issuing similar mandates, and we expect this trend will continue. 

Moreover, consumer acceptance and market penetration of electric, hybrid and alternative fuel vehicles continues to increase. In 
2021, several automobile manufacturers jointly announced their shared goal that 40-50% of their new vehicle sales be battery 
electric, fuel cell or plug-in hybrid vehicles by 2030. Other automobile manufacturers have similar, or more aggressive, goals with 
respect to vehicle electrification. Technological breakthroughs relating to renewable fuels or other fuel alternatives such as 
hydrogen or ammonia, or efficiency improvements for internal combustion engines could reduce demand for petroleum-based 
transportation fuels.

Together, these trends and developments have had and are expected to continue to have an adverse effect on sales of our 
petroleum-based transportation fuels, which in turn 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.

Our operations are subject to business interruptions, such as scheduled and unscheduled refinery turnarounds, unplanned 
maintenance, explosions, fires, refinery or pipeline releases, product quality incidents, power outages, severe weather, labor 
disputes, acts of terrorism, or other natural or man-made disasters. These types of incidents adversely affect our operations and 
may result in serious personal injury or loss of human life, significant damage to property and equipment, impaired ability to 
manufacture our products, environmental pollution, and substantial losses. We have experienced certain of these incidents in the 
past. 

For assets located near populated areas, the level of damage resulting from such an incident 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 are increasingly dependent on the performance of our information technology systems and those of our third-party 
business partners and service providers.

We are increasingly dependent on our information technology systems and those of our third-party business partners and service 
providers 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 and investor data, 
and to manage or support a variety of business processes, including our supply chain, pipeline operations, gathering and 
processing operations, credit card payments and authorizations at certain of our customers’ retail outlets, financial transactions, 
banking and numerous other processes and transactions. 

Our systems (and those of our third-party business partners and service providers) are subject to numerous and evolving 
cybersecurity threats and attacks, including ransomware and other malware, and phishing and social engineering schemes, 
which can compromise our ability to operate, and the confidentiality, availability, and integrity of data in our systems or those of 
our third-party business partners and service providers. These and other cybersecurity threats may originate with criminal 
attackers, state-sponsored actors or employee error or malfeasance. Because the techniques used to obtain unauthorized 
access, or to disable or degrade systems continuously evolve and have become increasingly complex and sophisticated, and 
can remain undetected for a period of time despite efforts to detect and respond in a timely manner, we (and our third-party 
business partners and service providers) are subject to the risk of cyberattacks.

18

Our cybersecurity and infrastructure protection technologies, disaster recovery plans and systems, employee training and vendor 
risk management may not be sufficient to defend us against all unauthorized attempts to access our information or impact our 
systems. We and our third-party vendors and service providers have been and may in the future be subject to cybersecurity 
events of varying degrees. To date, the impacts of prior events have not had a material adverse effect on us.

Cybersecurity events involving our information technology systems or those of our third-party business partners and service 
providers can result in theft, destruction, loss, misappropriation or release of confidential financial data, regulated personally 
identifiable information, intellectual property and other information; give rise to remediation or other expenses; result in litigation, 
claims and increased regulatory review or scrutiny; reduce our customers’ willingness to do business with us; disrupt our 
operations and the services we provide to customers; and subject us to litigation and legal liability under international, U.S. 
federal and state laws. Any of such results could have a material adverse effect on our reputation, business, financial condition, 
results of operations and cash flows.

The availability and cost of renewable identification numbers could have an adverse effect on our financial condition 
and results of operations.

Pursuant to the Energy Policy Act of 2005 and the EISA, Congress established a Renewable Fuel Standard (“RFS”) program that 
requires annual volumes of renewable fuel be blended into domestic transportation fuel. A RIN is assigned to each gallon of 
renewable fuel produced in, or imported into, the United States. As a producer of petroleum-based motor fuels, we are obligated 
to blend renewable fuels into the products we produce at a rate that is at least commensurate to EPA’s quota and, to the extent 
we do not, we must purchase RINs in the open market to satisfy our obligation under the RFS program. We are exposed to the 
volatility in the market price of RINs. We cannot predict the future prices of RINs. RINs prices are dependent upon a variety of 
factors, including EPA regulations, the availability of RINs for purchase, and levels of transportation fuels produced, which can 
vary significantly from quarter to quarter. There is currently no regulatory method for verifying the validity of most 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. See Item 1. Business – Regulatory Matters for additional information on these 
and other regulatory compliance matters. 

Competitors that produce their own supply of feedstocks, own their own retail sites, or have greater financial resources 
may have a competitive advantage.

The refining and marketing industry is highly competitive with respect to both feedstock supply and refined petroleum products. 
We compete with many companies for available supplies of crude oil and other feedstocks, and we do not produce any of our 
crude oil feedstocks. Our competitors include multinational, integrated major oil companies that can obtain a significant portion of 
their feedstocks from company-owned production. Competitors that produce crude oil are at times better positioned to withstand 
periods of depressed refining margins or feedstock shortages. 

We also compete with other companies for customers for our refined petroleum products. The independent entrepreneurs who 
operate primarily Marathon-branded outlets and the direct dealer locations we supply compete with other convenience store 
chains, outlets owned or operated by 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. The loss of market share by those who 
operate our branded outlets and the direct dealer locations we supply could adversely affect our business, financial condition, 
results of operations and cash flows.

The COVID-19 pandemic has had, and may continue to have, a material and adverse effect on our and our customers’ 
business and on general economic, financial and business conditions. 

The COVID-19 pandemic and existing COVID-19 mitigation measures have had adverse effects on global travel and economic 
activity and, consequently, demand for the petroleum products that we manufacture, sell, transport and store. While demand for 
the petroleum products that we manufacture, sell, transport and store witnessed a substantial recovery in 2022, significant 
uncertainty remains as to the extent to which further resurgences in the virus, the emergence of new variants and waning 
vaccine effectiveness may spur future actions by individuals, governments and the private sector to stem the spread of the virus. 

The extent to which the COVID-19 pandemic continues to impact global economic conditions, our business and the business of 
our customers, suppliers and other counterparties, will depend largely on future developments that remain uncertain and cannot 
be predicted, such as the length and severity of the pandemic; the social, economic and epidemiological effects of COVID-19 
mitigation measures; the extent to which individuals acquire and retain immunity; emerging virus variants and how those new 
variants of the disease affect the human body; the stress on access to materials, supplies and contract labor; and general 
economic conditions. 

Additionally, the continuation of the pandemic could precipitate or aggravate the other risks identified in this Form 10-K, which in 
turn could further materially and adversely affect our business, financial condition and results of operations, including in ways not 
currently known or considered by us to present significant risks.

19

We may be negatively impacted by inflation.

Increases in inflation may have an adverse effect on us. Current and future inflationary effects may be driven by, among other 
things, supply chain disruptions and governmental stimulus or fiscal policies. Continuing increases in inflation could impact the 
commodity markets generally, the overall demand for our products and services, our costs for labor, material and services and 
the margins we are able to realize on our products, all of which could have an adverse impact on our business, financial position, 
results of operations and cash flows. Inflation may also result in higher interest rates, which in turn would result in higher interest 
expense related to our variable rate indebtedness and any borrowings we undertake to refinance existing fixed rate 
indebtedness.

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 or limited because of weather 
events, accidents, labor disputes, 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, can adversely affect us. 

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.

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 lead to decreases in 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 can result in producers deciding to limit their oil and gas drilling 
operations, which can 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, other climate conditions and earth movement and other geological hazards may adversely 
affect our assets and ongoing operations.

Our assets are subject to acute physical risks, such as floods, hurricane-force winds, wildfires, winter storms, and earth 
movement in variable, steep and rugged terrain and terrain with varied or changing subsurface conditions, and chronic physical 
risks, such as sea-level rise or water shortages. For example, in 2021, our Galveston Bay refinery was adversely affected by 
Winter Storm Uri and our Garyville refinery was adversely affected by Hurricane Ida. The occurrence of these and similar events 
have had, and may in the future 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 

20

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. 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, supply chain disruptions, duties and tariffs, transportation delays, difficulty in enforcing contractual provisions, 
import and export controls, changes in governmental policies, political and social unrest, security issues involving key personnel 
and changing regulatory and political environments. Future outbreaks of infectious diseases or pandemics could affect demand 
for refined products and economic conditions generally, as the COVID-19 pandemic has done in recent years. In addition, the 
deterioration of trade relationships, modification or termination of existing trade agreements, imposition of new economic 
sanctions against Russia or other countries and the effects of potential responsive countermeasures, or increased taxes, border 
adjustments or tariffs can make international business operations more costly, which can 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. 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, Russia or elsewhere or the occurrence or threat 
of future terrorist attacks could adversely affect the economies of the U.S. and other countries. Lower levels of economic activity 
often result in a decline in energy consumption, which may 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 or revoke or refuse to grant necessary permits.

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 or other targeted operational disruptions may affect our facilities or those of our customers and 
suppliers. 

Refining, gathering and processing, pipeline and terminal infrastructure, and other energy assets, may be the subject of terrorist 
attacks or other targeted operational disruptions. Any attack or targeted disruption of our operations, those of our customers or, in 
some cases, those of other energy industry participants, could have a material and adverse effect on our business. Similarly, any 
similar event that severely disrupts 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, 2022, our total debt obligations for borrowed money and finance lease obligations were $27.08 billion, including 
$20.11 billion of obligations of MPLX and its subsidiaries. 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; 

21

•

•

•

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. 

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. Any changes in our credit capacity or credit profile could materially 
and adversely affect our business, financial condition, results of operations and cash flows.

Significant variations in the market prices of crude oil and refined products can affect our financial performance.

During 2020, there were significant variations in the market prices of products held in our inventories. Those significant 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. 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. 

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

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. 

Increases in interest rates could adversely impact our share price, our ability to issue equity or incur debt for 
acquisitions or other purposes and our ability to make dividends at our intended levels.

Our revolving credit facility has a variable interest rate. As a result, future interest rates on our debt could be higher than current 
levels, causing our financing costs to increase accordingly. In addition, we may in the future refinance outstanding borrowings 
under our revolving credit facility with fixed-rate indebtedness. Interest rates payable on fixed-rate indebtedness typically are 
higher than the short-term variable interest rates that we pay on borrowings under our revolving credit facility. We also have other 
fixed-rate indebtedness that we may need or desire to refinance in the future at or prior to the applicable stated maturity. A rising 
interest rate environment could have an adverse impact on our share price and our ability to issue equity or incur debt for 
acquisitions or other purposes and to make dividends at our intended levels.

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 assets or operations can 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.

22

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, 2022, our balance sheet reflected $8.2 billion and $1.9 billion of goodwill and other intangible assets, 
respectively. We have in the past recorded significant impairments of our goodwill. 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 be subject to delays, 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, whether due to inflation or other factors;

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; 

•

•

•

global supply chain disruptions;

nonperformance by, or disputes with, vendors, suppliers, contractors or subcontractors; and

delays due to citizen, state or local political or activist pressure.

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. 

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 capital project returns and 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 and services.

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,

climate change and GHG emissions,

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.

23

The specific impact of laws and regulations 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 have incurred and may in the future incur liability for personal injury, property damage, natural resource 
damage or clean-up costs due to alleged contamination and/or exposure to chemicals such as benzene and MTBE. There is also 
increased regulatory interest in per- and polyfluoroalkyl substances (“PFAS”), which we expect will lead to increased monitoring 
and remediation obligations and potential liability related thereto. 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. If 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.

The tax treatment of publicly traded partnerships or an investment in MPLX units could be subject to potential 
legislative, judicial or administrative changes and differing interpretations, possibly on a retroactive basis.

The present U.S. federal income tax treatment of publicly traded partnerships, including MPLX, or an investment in MPLX 
common units may be modified by administrative, legislative or judicial interpretation at any time. From time to time, the 
President and members of the U.S. Congress propose and consider substantive changes to the existing U.S. federal income tax 
laws that would affect publicly traded partnerships, including proposals that would eliminate MPLX’s ability to qualify for 
partnership tax treatment. 

We are unable to predict whether any such changes will ultimately be enacted. Any modification to the U.S. federal income tax 
laws and interpretations thereof may or may not be applied retroactively and could make it more difficult or impossible for MPLX 
to meet the exception for certain publicly traded partnerships to be treated as partnerships for U.S. federal income tax purposes 
or increase the amount of taxes payable by unitholders in publicly traded partnerships.

Climate change and GHG 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 GHG (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 GHG 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, California and Washington have enacted cap-and-trade programs. 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.

Certain municipalities have also proposed or enacted restrictions on the installation of natural gas appliances and infrastructure 
in new residential or commercial construction, which could affect demand for the natural gas that MPLX transports and stores.

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 intensity have also resulted in societal concerns and a 
number of international and national measures to limit GHG 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 

24

emissions from the oil and gas sector as quickly as possible, and requires federal permitting decisions to consider the effects of 
GHG 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 GHG 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 GHG regulation is unknown at this time.

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

Governmental and other entities in various U.S. states have filed lawsuits against various energy 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, and may in the future be subject to, litigation seeking 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 of public 
sentiment on GHG emissions, climate change, and climate adaptation. Additionally, societal sentiment regarding carbon-based 
fuels may adversely impact our reputation and ability to attract and retain employees.

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 GHG 
emissions downstream of pipeline operations. 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. 

Increasing attention to environmental, social and governance matters may impact our business and financial results.

In recent years, increasing attention has been given to corporate activities related to ESG matters in public discourse and the 
investment community. A number of advocacy groups, both domestically and internationally, have campaigned for governmental 
and private action to promote ESG-related change at public companies, including, but not limited to, through the investment and 
voting practices of investment advisers, pension funds, universities and other members of the investing community. These 
activities include increasing attention and demands for action related to climate change and energy transition matters, such as 
promoting the use of substitutes to fossil fuel products and encouraging the divestment of fossil fuel equities, as well as 
pressuring lenders and other financial services companies to limit or curtail activities with fossil fuel companies. If this were to 
continue, it could have a material adverse effect on our access to capital. Members of the investment community have begun to 
screen companies such as ours for sustainability performance, including practices related to GHG emission reduction and 
energy transition strategies. If we are unable to find economically viable, as well as publicly acceptable, solutions that reduce our 
GHG emissions, reduce GHG intensity for new and existing projects, increase our non-fossil fuel product portfolio, and/or 
address other ESG-related stakeholder concerns, our business and results of operations could be materially and adversely 
affected.

Our goals, targets and disclosures related to ESG matters expose us to numerous risks, including risks to our 
reputation and stock price. 

Companies across all industries are facing increasing scrutiny from stakeholders related to ESG matters, including practices and 
disclosures regarding climate-related initiatives. In 2022, MPC established a target to reduce GHG emissions and MPLX 
established a target to reduce methane emissions intensity. These targets reflect our current plans and aspirations and are not 
guarantees that we will be able to achieve them. Our efforts to accomplish and accurately report on these goals and objectives, 
which may be, in part, dependent on the actions of suppliers and other third parties, present numerous operational, regulatory, 
reputational, financial, legal, and other risks, any of which could have a material negative impact, including on our reputation and 
stock price.

Efforts to achieve goals and targets, such as the foregoing and future internal climate-related initiatives, may increase costs, 
require purchase of carbon credits, or limit or impact our business plans and financial results, potentially resulting in the reduction 

25

to the economic end-of-life of certain assets and an impairment of the associated net book value, among other material adverse 
impacts. Additionally, as the nature, scope and complexity of ESG reporting, calculation methodologies, voluntary reporting 
standards and disclosure requirements expand, including the SEC’s proposed disclosure requirements regarding, among other 
matters, GHG emissions, we may have to undertake additional costs to control, assess and report on ESG metrics. Our failure or 
perceived failure to pursue or fulfill such goals and targets or to satisfy various reporting standards within the timelines we 
announce, or at all, could have a negative impact on investor sentiment, ratings outcomes for evaluating our approach to ESG 
matters, stock price, and cost of capital and expose us to government enforcement actions and private litigation, among other 
material adverse impacts.

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. 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 3,755 of our employees are covered by collective bargaining agreements. Approximately 2,545 refinery 
employees are covered by collective bargaining agreements with expiration dates ranging from 2023 to 2027. 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. 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.

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, we could be prohibited from operating vessels engaged in 
U.S. coastwise trade, which could adversely affect our business, financial condition, results of operations and cash 
flows.

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, we 

26

would be prohibited from operating vessels in the U.S. inland waters or otherwise in U.S. coastwise trade. 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. For example, a portion of the Tesoro High Plains pipeline in North Dakota remains 
shut down following delays in renewing a right-of-way necessary for the operation of a section of the pipeline. Any loss of or 
reduction in our real property 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 can increase our costs and delay or prevent our efforts to conduct operations.

Various federal agencies within the U.S. Department of the Interior, particularly the Bureau of Indian Affairs, along with each 
Native American tribe, regulate natural gas and oil operations on Native American tribal lands. 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 has in the past and may in the 
future 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. For example, we are subject to ongoing litigation regarding trespass claims relating 
to a portion of the Tesoro High Plains pipeline in North Dakota.

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.

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; 

27

•

•

•

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 

Following the Speedway sale, our diminished diversification of revenue sources may adversely affect our results of 
operations and financial condition. 

On May 14, 2021, we completed the sale of Speedway, our company-owned and operated retail transportation fuel and 
convenience store business, to 7-Eleven. Following the completion of the sale, our diversification of revenue sources diminished, 
and 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 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.

28

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, state and local income taxes in the United States and in foreign 
jurisdictions, and, transactional, payroll, franchise, withholding and property taxes. New tax laws and regulations and changes in, 
interpretations of, and guidance regarding tax laws and regulations, including impacts of the Tax Cuts and Jobs Act of 2017, the 
Coronavirus Aid, Relief, Economic Security Act of 2020, and the Inflation Reduction Act of 2022, 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.

In addition, we are subject to the examination of our returns by taxing authorities. We regularly assess the likelihood of adverse 
outcomes resulting from such examinations to determine the adequacy of our provision for income taxes. Although we believe 
we have made appropriate provisions for taxes in the jurisdictions in which we operate, changes in the tax laws or challenges 
from tax authorities under existing tax laws could adversely affect our business, financial condition and results of operations and 
could subject us to interest and penalties.

Item 3. Legal Proceedings

We are the subject of, or a party to, a number of pending or threatened legal actions, contingencies and commitments involving a 
variety of matters, including laws and regulations relating to the environment. While it is possible that an adverse result in one or 
more of the lawsuits or proceedings in which we are a defendant could be material to us, based upon current information and our 
experience as a defendant in other matters, we believe that these lawsuits and proceedings, individually or in the aggregate, will 
not have a material adverse effect on our consolidated results of operations, financial position or cash flows.

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 a 
specified threshold. We use a threshold of $1 million for this purpose. 

Climate Change Litigation

Governmental and other entities in various states have filed climate-related lawsuits against a number of 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. Similar lawsuits may be filed in other jurisdictions. The names of the courts in which 
the proceedings are pending and the dates instituted are as follows:

MPLX holds a 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. In 
2020, the D.D.C. ordered the Army Corps, which granted permits and an easement for the Bakken Pipeline system, to prepare 
an environmental impact statement (“EIS”) relating to an easement under Lake Oahe in North Dakota. The D.D.C. later vacated 
the easement. The Army Corps expects to release a draft EIS in 2023. 

In May 2021, the D.D.C. denied a renewed request for an injunction to shut down the pipeline while the EIS is being prepared. In 
June 2021, the D.D.C. issued an order dismissing without prejudice the tribes’ claims against the Dakota Access Pipeline. The 
litigation could be reopened or new litigation challenging the EIS, once completed, could be filed. The pipeline remains 
operational.

36

MPLX has entered into a Contingent Equity Contribution Agreement whereby it, 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. If the 
pipeline were temporarily shut down, 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. MPLX also expects to 
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 1% redemption premium required 
pursuant to the indenture governing the notes) and any accrued and unpaid interest. As of December 31, 2022, our maximum 
potential undiscounted payments under the Contingent Equity Contribution Agreement were approximately $170 million.

Tesoro High Plains Pipeline

In July 2020, Tesoro High Plains Pipeline Company, LLC (“THPP”), a subsidiary of 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 demanded the immediate cessation of pipeline operations and 
assessed trespass damages of approximately $187 million. After subsequent appeal proceedings and in compliance with a new 
order issued by the BIA, in December 2020, THPP paid approximately $4 million in assessed trespass damages and ceased use 
of the portion of the pipeline that crosses the property at issue. In March 2021, the BIA issued an order purporting to vacate the 
BIA's prior orders related to THPP’s alleged trespass and direct the Regional Director of the BIA to reconsider the issue of 
THPP’s alleged trespass and issue a new order. In April 2021, THPP filed a lawsuit in the District of North Dakota against the 
United States of America, the U.S. Department of the Interior and the BIA (together, the “U.S. Government Parties”) challenging 
the March 2021 order purporting to vacate all previous orders related to THPP’s alleged trespass. On February 8, 2022, the U.S. 
Government Parties filed their answer and counterclaims to THPP’s suit claiming THPP is in continued trespass with respect to 
the pipeline and seek disgorgement of pipeline profits from June 1, 2013 to present, removal of the pipeline and remediation. We 
intend to vigorously defend ourselves against these counterclaims.

Martinez Refinery

We have resolved 99 NOVs received from the Bay Area Air Quality Management District (“BAAQMD”) through settlement with 
the BAAQMD that includes payment of a cash penalty of approximately $1.5 million. The NOVs were issued from 2011 to 2018 
and allege violations of air quality regulations and the idled Martinez refinery’s air permit. 

On July 18, 2016, the U.S. Department of Justice (“DOJ”) lodged a complaint on behalf of 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 2018, TRMC informed EPA that it would need additional time to satisfy 
requirements of the Consent Decree. In 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, contingent 
on TRMC completing the conversion of the Martinez refinery to renewable diesel production, 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

MPLX has been negotiating with the EPA with respect to 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 as 
well as the Robinson Lake Gas Plant in North Dakota. MPLX is in the process of finalizing a settlement with the EPA pursuant to 
which MPLX expects to pay a cash penalty of $2 million, incorporate additional remedial measures, mitigate excess emissions 
associated with events and enter into a consent decree covering MPLX gas plants and compressor stations located in Utah, 
North Dakota and Wyoming. We expect the settlement to be finalized later in 2023.

Edwardsville Incident

In March 2022, the State of Illinois brought an action in Madison County Circuit Court in Illinois against Marathon Pipe Line LLC, 
an indirect wholly owned subsidiary of MPLX, asserting various violations and demanding a permanent injunction and civil 
penalties in connection with a March 2022 release of crude oil on the Wood River to Patoka 22" line near Edwardsville, Illinois. 
We are negotiating a settlement of the allegations. We cannot currently estimate the amount of any civil penalty or the timing of 
the resolution of this matter but do not believe any civil penalty will have a material impact on our consolidated results of 
operations, financial position or cash flows.

All statements in this section, other than statements of historical fact, are forward-looking statements that are inherently 
uncertain. See “Disclosures Regarding Forward-Looking Statements” and Item 1A. Risk Factors for a discussion of the factors 
that could cause actual results to differ materially from those projected in these statements. The following information concerning 
our business, results of operations and financial condition should also be read in conjunction with the information included under 
Item 1. Business, Item 1A. Risk Factors and Item 8. Financial Statements and Supplementary Data.

EXECUTIVE SUMMARY

Business Update

For the year ended December 31, 2022, our results were favorably impacted by the continuing recovery in the environment in 
which our business operates. The increase in global demand for refined products and global commodity supply constraints have 
contributed to increases in the market prices of petroleum-based transportation fuels and in Refining & Marketing margins and 
Midstream throughputs. Supply has remained constrained for a variety of reasons, including, but not limited to, effects from 
refinery closures and disruptions in the crude oil and petroleum-based products markets resulting from the Russia-Ukraine 
conflict. We are unable to predict the potential effects that resurgences of COVID-19 or the continuance or escalation of the 
military conflict between Russia and Ukraine, and related sanctions or market disruptions, may have on our financial position and 
results. It remains uncertain how long these conditions may last or how severe they may become.

In 2022, data indicated a sharp rise in inflation in the U.S. and globally. Current and future inflationary effects may be driven by, 
among other things, supply chain disruptions, governmental stimulus or fiscal policies and increasing demand for certain goods 
and services as recovery from the COVID-19 pandemic continues. We have observed higher costs for feedstocks, labor and 
materials used in our business. We cannot predict the effect of rising interest rates, the concerns of a recession and higher 
inflation and fuel prices on demand for our products and services.

In response to this business environment, we continue to focus on the following priorities for our business:

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. A near-
term focus has been securing advantaged renewable feedstocks as we continue to advance our renewable fuels production 
capabilities. This includes exploring joint venture opportunities and strategic alliances within the renewable fuels value chain.

Continued Capital Discipline and Focus on Low-Cost Culture

We are committed to achieving operational excellence by reducing costs, improving efficiency, driving operational improvements 
and being disciplined in capital allocation. This means lowering our costs in all aspects of our business and challenging 
ourselves to be disciplined in every dollar we spend across our organization. We look to optimize our portfolio of investment 
opportunities to ensure efficient deployment of capital focusing on projects with the highest returns.

Commitment to Sustainability

Our approach to sustainability spans the environmental, social and governance dimensions of our business. That means 
strengthening resiliency by lowering the carbon intensity and conserving natural resources; innovating for the future by investing 
in renewables and emerging technologies; and embedding sustainability in decision-making and in how we engage our people 
and many stakeholders. Specifically, in 2022, we were the first among U.S. independent refiners to establish a 2030 target to 
reduce absolute Scope 3 - Category 11 GHG emissions. This goal added to our existing targets for reducing Scope 1 & 2 GHG 
emissions intensity, for lowering methane emissions intensity and for lowering our freshwater withdrawal intensity. Additionally, 
MPLX is progressing towards meeting its 2025 and 2030 methane intensity reduction goals, as well as its biodiversity target, by 
applying sustainable landscapes to its compatible right of ways.

Strategic Updates

Martinez Renewable Fuels Project Joint Venture

On September 21, 2022, MPC closed on the formation of the Martinez Renewable joint venture. The partnership is structured as 
a 50/50 joint venture with Neste expected to contribute a total of $1 billion. These contributions will continue into 2023. At the 
closing date, MPC contributed property, plant and equipment, inventory, and working capital valued at $1.47 billion and Neste 
contributed $728 million in cash. MPC recorded a gain of $549 million resulting from the difference between the carrying value 
and fair value of the contributed property, plant and equipment and inventory. Subsequent to the closing, the joint venture paid a 
special distribution to MPC of $500 million, which is reflected as a return of capital in MPC’s consolidated statements of cash 
flows. At December 31, 2022, MPC’s investment value in the entity is approximately $1.07 billion. 

MPC will continue to manage project execution and operate the facility once construction is complete. The annual feedstock 
supply requirements are split between the joint venture partners, which include specific commitments to supply advantaged 
feedstocks. The annual production output will be shared evenly between the joint venture partners, and each partner will have 
the ability to market its share of the products. The joint venture, being optimally located to strengthen both partners' footprint in 
renewable fuels, will utilize existing processing infrastructure and diverse inbound and outbound logistics.

This strategic partnership is expected to advance the current project objectives of delivering low carbon intensity fuels to support 
California's climate goals. MPC and Neste will leverage their complementary core competencies in the joint venture. MPC brings 
experience in renewable diesel facility conversion, large capital project execution and operating expertise in the California 
market. Neste brings knowledge in sustainable feedstock sourcing and in renewable liquid fuels production. The joint venture 
reflects both partners' commitment to obtain low carbon intensity feedstocks to achieve the project objectives of providing fuels 
that meet the demand driven by the Low Carbon Fuel Standard. 

The facility is expected to ramp up to producing 730 million gallons per year by the end of 2023, with pretreatment capabilities 
coming online in 2023. 

Share Repurchase Authorization

As of December 31, 2022, MPC had $3.33 billion remaining under its share repurchase authorizations. On January 31, 2023, the 
company announced that its Board of Directors had approved an incremental $5.0 billion share repurchase authorization. Future 
repurchases under this incremental authorization will depend on the macro environment, cash available after opportunities for 
capital investment and growth of the business and market conditions. This authorization is in addition to a $5.0 billion share 
repurchase authorization announced on August 2, 2022 and a $5.0 billion share repurchase authorization announced on 
February 2, 2022. The authorizations have no expiration date.

Results

During the first quarter of 2022, our chief operating decision maker (“CODM”) began to evaluate the performance of our 
segments using segment adjusted EBITDA. We have modified our presentation of segment performance to be consistent with 
this change, including prior periods presented for consistent and comparable presentation. Amounts included in net income and 
excluded from segment adjusted EBITDA include: (i) depreciation and amortization; (ii) provision for income taxes; (iii) net 
interest and other financial costs; (iv) noncontrolling interests; (v) turnaround expenses and (vi) other adjustments as deemed 
necessary. These items are either: (i) believed to be non-recurring in nature; (ii) not believed to be allocable or controlled by the 
segment; or (iii) are not tied to the operational performance of the segment.

Select results for continuing operations for 2022 and 2021 are reflected in the following table.

Net income attributable to MPC increased $4.78 billion, or $12.88 per diluted share, in 2022 compared to 2021 primarily due to 
increased average refined product sales prices and volumes and non-cash net gains on the disposal of assets, partially offset by 
increased operating costs and the absence of a gain on the sale of Speedway and a partial period of income from discontinued 
operations due to the sale of the Speedway business on May 14, 2021.

MPLX

We received limited partner distributions of $1.87 billion and $2.16 billion from MPLX during 2022 and 2021, respectively. The 
decrease in 2022 is primarily due to a supplemental distribution amount of $0.5750 per common unit in the third quarter of 2021 
that did not recur in 2022. We owned approximately 647 million MPLX common units at December 31, 2022 with a market value 
of $21.26 billion based on the December 30, 2022 closing unit price of $32.84. On January 25, 2023, MPLX declared a quarterly 
cash distribution of $0.7750 per common unit, which was paid February 14, 2023. As a result, MPLX made distributions totaling 
$776 million to its common unitholders. MPC’s portion of this distribution was approximately $502 million.

During the year ended December 31, 2022, MPLX repurchased 15 million common units at an average cost per unit of $31.96 
and paid $491 million of cash. As of December 31, 2022, $846 million remained available under the authorization for future 
repurchases.

On February 9, 2023, MPLX issued $1.1 billion aggregate principal amount of 5.00% senior notes due 2033 and $500 million 
aggregate principal amount of 5.65% senior notes due 2053 in an underwritten public offering. 

On February 15, 2023, MPLX redeemed all of the 600,000 outstanding Series B preferred units at the redemption price of $1,000 
per unit. The semi-annual distribution due to Series B unitholders on February 15, 2023, was also paid on that date, in the usual 
manner. MPLX also provided notice to redeem all of MPLX’s and MarkWest’s $1.0 billion aggregate principal amount of 4.50% 
senior notes due July 2023.

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

OVERVIEW OF SEGMENTS

Refining & Marketing

Refining & Marketing segment adjusted EBITDA depends largely on our refinery throughputs, Refining & Marketing margin, 
refining operating costs and distribution costs. Our total refining capacity was 2,898 mbpcd, 2,887 mbpcd and 2,874 mbpcd as of 
December 31, 2022, 2021 and 2020, 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 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 MEH 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.

Crack spread based on 40 percent MEH, 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 assume 
approximately 50 percent of the crude processed at our refineries in 2023 will be sour crude.

Sweet crude oil basket consists of the following crudes: Bakken, Brent, MEH, WTI-Cushing and WTI-Midland. We assume approximately 50 
percent of the crude processed at our refineries in 2023 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;

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

the cost of purchasing RINs in the open market to comply with RFS2 requirements.

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, 2022, 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.

Refining & Marketing segment adjusted EBITDA is also affected by changes in refining operating 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. Distribution costs primarily include long-term agreements with MPLX, 
which as discussed below include minimum commitments to MPLX, and will negatively impact segment adjusted EBITDA in 
periods when throughput or sales are lower or refineries are idled.

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

Midstream

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

43

 
 
 
 
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 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.

In accordance with discontinued operations accounting, Speedway sales to retail customers and net results are reflected in Income from 
discontinued operations, net of tax, and Refining & Marketing intercompany sales to Speedway are presented as third-party sales through 
the close of the sale on May 14, 2021.

2022 Compared to 2021 

Net income attributable to MPC increased $4.78 billion in 2022 compared to 2021, primarily due to increased average refined 
product sales prices and volumes and net gains on the disposal of assets, partially offset by increased operating costs and the 
absence of a gain on the sale of Speedway and a partial period of income from discontinued operations due to the sale of the 
Speedway business on May 14, 2021.

Total revenues and other income increased $59.02 billion in 2022 compared to 2021 primarily due to:

•

•

increased sales and other operating revenues of $57.47 billion primarily due to increased average refined product sales 
prices of $0.96 per gallon, or 47 percent, and refined product sales volumes of 83 mbpd, or 2 percent, largely due to 
continuing recovery in demand for our products across all our regions;

increased income from equity method investments of $197 million largely due to increased income from midstream 
equity affiliates;

•

•

increased net gains on disposal of assets of $1.04 billion mainly due to a gain of $549 million on the formation of the 
Martinez Renewable joint venture and a gain of $509 million on a lease reclassification; and

increased other income of $315 million primarily due to higher income on RIN sales.

Total costs and expenses increased $41.85 billion in 2022 compared to 2021 primarily due to:

•

•

•

•

increased cost of revenues of $41.66 billion primarily due to higher crude oil costs and finished product purchases;

decreased depreciation and amortization of $149 million mainly due to 2021 Midstream asset impairments and assets 
that were fully depreciated in 2021;

increased selling, general and administrative expenses of $235 million mainly due to increased salaries, benefits and 
employee related expenses, credit card processing fees, contract services and insurance: and

increased other taxes of $104 million largely due to retroactive operating tax assessments for prior periods. 

Net interest and other financial costs decreased $483 million largely due to increased interest income, decreased debt retirement 
expenses related to the redemption of MPC senior notes in 2021, decreased interest expense due to lower MPC borrowings and 
decreased pension and other postretirement non-service costs, partially offset by increased interest expense due to higher 
MPLX borrowings. We capitalized interest of $104 million in 2022 and $73 million in 2021. See Item 8. Financial Statements and 
Supplementary Data – Note 13 for further details.

We recorded a combined federal, state and foreign income tax expense of $4.49 billion for the year ended December 31, 2022, 
which was higher than the tax computed at the U.S. statutory rate primarily due to state taxes, partially offset by permanent tax 
benefits related to net income attributable to noncontrolling interests. We recorded a combined federal, state and foreign income 
tax expense of $264 million for the year ended December 31, 2021, which was lower than the tax computed at the U.S. statutory 
rate primarily due to certain permanent tax benefits related to net income attributable to noncontrolling interests and a change in 
benefit related to the net operating loss (“NOL”) carryback provided under the Coronavirus Aid, Relief, and Economic Security 
Act (“CARES Act”), partially offset by state taxes. See Item 8. Financial Statements and Supplementary Data – Note 14 for 
further details.

Net income attributable to noncontrolling interests increased $283 million mainly due to an increase in MPLX’s net income.

2021 Compared to 2020 

Net income attributable to MPC increased $19.56 billion in 2021 compared to 2020 primarily due to the gain on the sale of 
Speedway, the absence of impairment expenses and a LIFO liquidation charge and increases in average refined product sales 
prices and volumes, partially offset by a partial period of income from discontinued operations due to the sale of the Speedway 
business on May 14, 2021. See Segment Results for additional information.

Total revenues and other income increased $51.90 billion in 2021 compared to 2020 primarily due to:

•

•

•

increased sales and other operating revenues of $50.20 billion primarily due to increased average refined product sales 
prices of $0.80 per gallon, or 65 percent, and refined product sales volumes of 203 mbpd, or 6 percent, largely due to 
continuing economic recovery from the impact of the COVID-19 pandemic in 2020;

increased income from equity method investments of $1.39 billion largely due to impairments of equity method 
investments of $1.32 billion in 2020 primarily driven by the effects of the COVID-19 pandemic and the decline in 
commodity prices; and 

increased other income of $350 million primarily due to higher income on RIN sales.

Total costs and expenses decreased $35.35 billion in 2021 compared to 2020 primarily due to:

•

•

•

•

increased cost of revenues of $44.28 billion primarily due to higher refined product sales volumes in addition to higher 
crude oil and refined product raw material costs, partially offset by the absence of a LIFO liquidation charge in 2020 of 
$561 million;

decreased impairment expense of $8.43 billion due to impairments recorded for goodwill and long-lived assets in 2020 
primarily driven by the effects of COVID-19 and the decline in commodity prices; 

decreased selling, general and administrative expenses of $173 million mainly due to cost reductions realized from our 
2020 workforce reduction and other cost control efforts; and

decreased restructuring expenses of $367 million related to the idling of the Martinez and Gallup refineries and costs 
related to our announced workforce reduction in 2020. See Item 8. Financial Statements and Supplementary Data – 
Note 19 for additional information.

Net interest and other financial costs increased $118 million largely due to debt retirement expenses related to the redemption of 
MPC senior notes and pension settlement losses of $75 million, partially offset by decreased interest expense due to lower 
MPLX and MPC borrowings. We capitalized interest of $73 million in 2021 and $129 million in 2020. See Item 8. Financial 
Statements and Supplementary Data – Note 13 for further details.

46

We recorded a combined federal, state and foreign income tax expense of $264 million for the year ended December 31, 2021, 
which was lower than the tax computed at the U.S. statutory rate primarily due to certain permanent tax benefits related to net 
income attributable to noncontrolling interests and a change in benefit related to the NOL carryback provided under the CARES 
Act, partially offset by state taxes. We recorded a combined federal, state and foreign income tax benefit of $2.43 billion for the 
year ended December 31, 2020, which is lower than the tax computed at the U.S. statutory rate primarily due to a significant 
amount of our pre-tax loss consisting of non-tax deductible goodwill impairment charges, partially offset by the tax rate differential 
resulting from the NOL carryback provided under the CARES Act. Additionally, our effective tax rate is generally benefited by our 
noncontrolling interest in MPLX, but this benefit was lower for the year ended December 31, 2020 due to goodwill and other 
impairment charges recorded by MPLX. See Item 8. Financial Statements and Supplementary Data – Note 14 for further details.

Net income attributable to noncontrolling interests increased $1.40 billion mainly due to an increase in MPLX’s net income largely 
due to impairment expense recognized during 2020.

Segment Results

We classify our business in the following reportable segments: Refining & Marketing and Midstream. Segment adjusted EBITDA 
represents adjusted EBITDA attributable to the reportable segments. Amounts included in net income and excluded from 
segment adjusted EBITDA include: (i) depreciation and amortization; (ii) provision for income taxes; (iii) net interest and other 
financial costs; (iv) noncontrolling interests; (v) turnaround expenses and (vi) other adjustments as deemed necessary. These 
items are either: (i) believed to be non-recurring in nature; (ii) not believed to be allocable or controlled by the segment; or (iii) are 
not tied to the operational performance of the segment.

Our segment adjusted EBITDA for reportable segments was approximately $25.03 billion, $8.93 billion and $3.12 billion for the 
years ended December 31, 2022, 2021 and 2020, respectively.

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 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. These blends are based on MPC’s refining capacity by region in each period. Beginning in the first quarter of 2021, the 
prompt price for USGC was transitioned from LLS to MEH.

2022 Compared to 2021 

Refining & Marketing segment revenues increased $56.71 billion primarily due to increased average refined product sales prices 
of $0.96 per gallon and higher refined product sales volumes, which increased 83 mbpd.

Refinery crude oil capacity utilization was 96 percent during 2022 and net refinery throughputs increased 152 mbpd primarily due 
to continuing recovery in demand for our products across all our regions.

Refining & Marketing segment adjusted EBITDA increased $15.74 billion primarily driven by higher per barrel margins, partially 
offset by increased refining operating costs and distribution costs, both excluding depreciation and amortization, and turnaround 
costs.

Refining & Marketing margin, excluding LIFO inventory credit of $148 million, was $28.10 per barrel for 2022 compared to $13.36 
per barrel for 2021. 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 approximately $18 billion on Refining & Marketing margin, primarily due to higher 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 2022, a LIFO inventory credit of $148 million. 
These factors had an estimated net negative impact on Refining & Marketing segment adjusted EBITDA of approximately $1.5 
billion in 2022 compared to 2021.

For the year ended December 31, 2022, refining operating costs, excluding depreciation and amortization and storm impacts, 
were $5.83 billion. This was an increase of $708 million, or $0.39 per barrel, compared to the year ended December 31, 2021 
primarily due to an increase in energy costs largely as a result of higher natural gas and electricity prices.

Distribution costs, excluding depreciation and amortization, were $5.27 billion and $5.15 billion for 2022 and 2021, respectively, 
and include fees paid to MPLX of $3.65 billion and $3.47 billion for 2022 and 2021, respectively. On a per barrel basis, 
distribution costs, excluding depreciation and amortization, decreased $0.15 due to higher throughput.

Refining planned turnaround costs increased $540 million, or $0.47 per barrel, due to the scope and timing of turnaround activity. 

Depreciation and amortization per barrel decreased by $0.11, primarily due to a decrease in costs and an increase in throughput.

We purchase RINs to satisfy a portion of our RFS2 compliance. Our expenses associated with purchased RINs were $2.40 
billion in 2022 and $1.49 billion in 2021 and are included in Refining & Marketing margin. The increase in 2022 was primarily due 
to higher weighted average RIN costs and an increase in RIN obligations due to higher production.

2021 Compared to 2020 

Refining & Marketing segment revenues increased $49.25 billion primarily due to increased average refined product sales prices 
of $0.80 per gallon and higher refined product sales volumes, which increased 203 mbpd.

Refinery crude oil capacity utilization was 91 percent during 2021 and net refinery throughputs increased 216 mbpd primarily due 
to continuing economic recovery from the impact of the COVID-19 pandemic in 2020.

Refining & Marketing segment adjusted EBITDA increased $5.46 billion primarily driven by higher blended crack spreads.

Refining & Marketing margin, excluding LIFO inventory charge, was $13.36 per barrel for 2021 compared to $8.96 per barrel for 
2020. 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 $5.0 billion on Refining & Marketing margin, primarily due to higher 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. These factors had an 
estimated net positive impact on Refining & Marketing segment adjusted EBITDA of approximately $700 million, including the 
LIFO inventory charge, in 2021 compared to 2020.

For the year ended December 31, 2021, refining operating costs, excluding depreciation and amortization and storm impacts, 
were $5.13 billion. This was a decrease of $241 million, or $0.66 per barrel, compared to the year ended December 31, 2020 as 
we took actions to reduce costs in response to the economic effects of the COVID-19 pandemic, including idling portions of our 
refining capacity, partially offset by an increase in energy costs largely as a result of higher natural gas prices. 

Distribution costs, excluding depreciation and amortization, were $5.15 billion and $5.08 billion for 2021 and 2020, respectively, 
and include fees paid to MPLX of $3.47 billion and $3.46 billion for 2021 and 2020, respectively. On a per barrel basis, 
distribution costs, excluding depreciation and amortization, decreased $0.33 due to increased throughput.

Refining planned turnaround costs decreased $250 million, or $0.31 per barrel, due to the timing of turnaround activity and an 
increase in throughput. 

Depreciation and amortization per barrel decreased by $0.13, primarily due to an increase in throughput partially offset by an 
increase in costs.

We purchase RINs to satisfy a portion of our RFS2 compliance. Our expenses associated with purchased RINs were $1.49 
billion in 2021 and $606 million in 2020 and are included in Refining & Marketing margin. The increase in 2021 was primarily due 
to higher weighted average RIN costs.

2022 Compared to 2021 

Midstream segment revenue and segment adjusted EBITDA increased $971 million and $362 million, respectively. Results 
largely benefited from higher product pricing, mainly due to increased average C2 + NGL prices of $0.16 per gallon. These price 
increases resulted in higher revenues of approximately $380 million, as well as higher cost of sales of $315 million. The 
Midstream segment also benefited from higher gathering system throughputs, resulting in increased revenue of $356 million, in 
addition to higher pipeline and terminal throughputs. Segment adjusted EBITDA increased primarily due to income from equity 
method investments of approximately $211 million. 

2021 Compared to 2020 

Midstream segment revenue and segment adjusted EBITDA increased $1.18 billion and $349 million, respectively. Results 
benefited from higher revenue, primarily due to higher natural gas prices, higher pipeline and terminal throughputs and lower 
operating expenses, partially offset by a decrease in marine transportation fees.

Corporate costs consist primarily of MPC’s corporate administrative expenses and costs related to certain non-operating assets, except for 
corporate overhead expenses attributable to MPLX, which are included in the Midstream segment. Corporate costs include depreciation and 
amortization of $55 million, $165 million and $165 million for the years ended December 31, 2022, 2021 and 2020, respectively.

2022 Compared to 2021 

Corporate expenses increased $57 million in 2022 compared to 2021 primarily driven by stock-based and special award 
compensation expense and retroactive operating tax assessments for prior periods. The company will continue to pursue 
recovery of these tax assessments. These increases were partially offset by decreased depreciation and amortization of $110 
million mainly due to 2021 asset impairments of $56 million and assets that were fully depreciated in 2021.

2021 Compared to 2020 

Corporate expenses decreased $104 million in 2021 compared to 2020 largely due to cost reductions realized from our 2020 
workforce reduction and other cost control efforts.

Non-GAAP Financial Measure

Management uses a financial measure to evaluate our operating performance that is calculated and presented on the basis of 
methodologies other than in accordance with GAAP. We believe this non-GAAP financial measure is useful to investors and 
analysts to assess our ongoing financial performance because, when reconciled to its most comparable GAAP financial 
measure, it provides 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. This measure 
should not be considered a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP, 
and our calculation thereof may not be comparable to similarly titled measures reported by other companies. The non-GAAP 
financial measure we use is 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.

Operating Activities

Continuing Operations

Net cash provided by operating activities from continuing operations increased $7.94 billion in 2022 compared to 2021, primarily 
due to an increase in operating results partially offset by an unfavorable change in working capital of $2.29 billion. Net cash 
provided by operating activities from continuing operations increased $7.58 billion in 2021 compared to 2020, primarily due to an 
increase in operating results and a favorable change in working capital of $633 million. The above changes in working capital 
exclude changes in short-term debt. 

For 2022, changes in working capital were a net $1.34 billion use of cash, primarily due to the effect of increases in energy 
commodity prices and volumes at the end of the year on working capital. Current receivables increased primarily due to higher 
crude and refined product volumes and prices. Inventories increased primarily due to increases in crude, refined product and 
materials and supplies inventories. Accounts payable increased primarily due to increases in crude prices.

For 2021, changes in working capital were a net $947 million source of cash, primarily due to the effect of increases in energy 
commodity prices and volumes at the end of the year on working capital. Accounts payable increased primarily due to increases 
in crude prices and volumes. Current receivables increased primarily due to higher crude and refined product prices and 
volumes.

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, 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 and supplies 
inventories.

Discontinued Operations

Net cash provided by operating activities from discontinued operations was $42 million in 2022 largely due to the settlement of 
working capital related to the Speedway sale, partially offset by the payment of state income tax liabilities. Net cash used in 
operating activities from discontinued operations was $4.02 billion in 2021 primarily due to tax payments related to the sale of 
Speedway, partially offset by a partial year of business income due to the sale of Speedway on May 14, 2021. Net cash provided 
by operating activities from discontinued operations in 2020 includes Speedway business income.

Investing Activities

Continuing Operations

Net cash provided by investing activities from continuing operations was $623 million in 2022, compared to net cash used of 
$6.52 billion and $2.92 billion in 2021 and 2020, respectively.

•

•

•

•

•

•

In 2022, the change in net cash provided by continuing operations was primarily due to maturities and sales of short-
term investments of $7.16 billion and $1.30 billion, respectively, partially offset by purchases of short-term investments 
of $6.02 billion. The cash provided by maturities and sales of short-term investments was primarily used to fund our 
return of capital initiatives announced as part of the Speedway sale.

In 2021, proceeds from the sale of Speedway were used to purchase $12.50 billion of short-term investments and cash 
of $5.41 billion and $1.54 billion was provided by the maturities and sales, respectively, of short-term investments. The 
cash provided by maturities and sales of short-term investments was primarily used to fund our return of capital 
initiatives announced as part of the Speedway sale.

Cash used for additions to property, plant and equipment was $2.42 billion in 2022, compared to $1.46 billion in 2021 
and $2.79 billion in 2020, primarily due to spending in our Refining & Marketing and Midstream segments in 2022. See 
discussion of capital expenditures and investments under the “Capital Spending” section.

Cash used for acquisitions was $413 million in 2022 primarily due to the purchase of Crowley Coastal Partner’s interest 
in Crowley Ocean Partners LLC and its four subsidiaries for approximately $485 million, which included $196 million to 
pay off the debt associated with the four tankers.

Cash provided by net investments was $110 million in 2022 compared to a net use of cash of $171 million in 2021 and 
$348 million in 2020. Investments in 2022 include a $500 million cash distribution received from the Martinez 
Renewable joint venture at its formation, partially offset by increased contributions to equity method investments, which 
included the $60 million contribution to MPLX’s Bakken Pipeline joint venture to fund its share of a debt repayment by 
the joint venture. Investments in 2021 primarily include midstream projects and our joint venture with ADM. The 
decrease from 2020 is due to the completion of the South Texas Gateway Terminal, the Gray Oak Pipeline and the 
Whistler Pipeline projects which were included in 2020 net investments. 

Cash provided by disposal of assets totaled $90 million, $153 million and $150 million in 2022, 2021 and 2020, 
respectively. In 2022 and 2021, we primarily sold Midstream assets and in 2020, we sold three asphalt terminals and 
other Refining & Marketing assets.

Net cash provided by investing activities from discontinued operations in 2021 primarily includes the $21.38 billion proceeds from 
the sale of Speedway, partially offset primarily by cash used for Speedway capital expenditures of $177 million. Net cash used in 
investing activities for discontinued operations for 2020 primarily includes Speedway capital expenditures.

Financing Activities

Financing activities were a use of cash of $13.65 billion in 2022, $14.42 billion in 2021 and $135 million in 2020.

During 2022, MPLX issued $2.5 billion of senior notes, redeemed $1.0 billion of senior notes and had net payments of 
$300 million under its revolving credit facility. 

During 2021, we reduced debt through the following actions:

•

•

•

•

On December 2, 2021, all of the $1.25 billion outstanding aggregate principal amount of MPC's 4.5% senior 
notes due May 2023 and the $850 million outstanding aggregate principal amount of MPC’s 4.75% senior 
notes due December 2023, including the portion of such notes for which Andeavor LLC was the obligor, were 
redeemed at a price equal to par, plus a make-whole premium calculated in accordance with the terms of the 
senior notes and accrued and unpaid interest to, but not including, the redemption date. MPC funded the 
redemption amount with cash on hand.

In June 2021, we redeemed all of the $300 million outstanding aggregate principal amount of MPC’s 5.125% 
senior notes due April 2024 at a price equal to 100.854% of the principal amount, plus accrued and unpaid 
interest to, but not including, the redemption date.

In May 2021, we repaid all outstanding commercial paper borrowings, which, along with cash had been used 
to finance the fourth quarter 2020 repayments of two series of MPC’s senior notes in the aggregate total 
principal amount of $1.13 billion.

On March 1, 2021, we repaid the $1 billion outstanding aggregate principal amount of MPC’s 5.125% senior 
notes due March 2021.

In 2021, MPLX redeemed $1.75 billion of senior notes and had net borrowings of $300 million under its revolving credit 
facility. 

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 and borrowed and repaid $3.55 billion under its trade receivables facility. 
MPLX issued $3.0 billion of senior notes, which were used to repay $1.0 billion of outstanding borrowings under its term 
loan, $1.0 billion of floating rate senior notes and to redeem $750 million of fixed rate senior notes and had net 
borrowings of $175 million under its revolving credit facility. 

Cash used in common stock repurchases totaled $11.92 billion in 2022 and $4.65 billion in 2021. See the “Capital 
Requirements” section for further discussion of our stock repurchases.

Cash used in dividend payments totaled $1.28 billion in 2022, $1.48 billion in 2021 and $1.51 billion in 2020. Dividends 
per share were $2.49 in 2022, $2.32 in 2021 and $2.32 in 2020. The decreases in 2022 and 2021 are primarily due to 
share repurchases, partially offset by an increase in per share dividends in 2022.

Cash used in distributions to noncontrolling interests totaled $1.21 billion in 2022, $1.45 billion in 2021 and $1.24 billion 
in 2020. MPLX’s distributions in 2021 included a supplemental distribution amount of $0.5750 per common unit. 

Cash used in repurchases of noncontrolling interests totaled $491 million in 2022, $630 million in 2021 and $33 million 
in 2020 due to MPLX’s repurchases of its common units. See the “Capital Requirements” section for further discussion 
of MPLX’s unit repurchases.

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, except as noted. MPC has effectively guaranteed certain 
indebtedness of LOOP and LOCAP, in which MPLX holds an interest. 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 $16.53 billion at December 31, 2022 consisting of:

The committed borrowing and letter of credit issuance capacity of the trade receivables securitization facility is $100 million. In addition, the 
facility allows for the issuance of letters of credit in excess of the committed capacity at the discretion of the issuing banks. As of 
December 31, 2022, letters of credit in the total amount of $1.05 billion were issued and outstanding under the facility to secure contracts 
awarded by the Department of Energy to purchase crude oil from the Strategic Petroleum Reserve.

Excludes $238 million of MPLX cash and cash equivalents. 

Because of the alternatives available to us, including internally generated cash flow and access to capital markets and a 
commercial paper program, we believe that our short-term and long-term liquidity is adequate to fund not only our current 
operations, but also our near-term (less than twelve months) and long-term funding requirements, including capital spending 
programs, the repurchase of shares of our common stock, dividend payments, defined benefit plan contributions, repayment of 
debt maturities and other amounts that may ultimately be paid in connection with contingencies. 

We have a commercial paper program that allows us to have a maximum of $2.0 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, 2022, we had no borrowings outstanding 
under the commercial paper program.

On July 7, 2022, MPC entered into a new five-year revolving credit agreement (the “MPC Credit Agreement”) to replace its 
previous $5.0 billion credit facility that was scheduled to expire in October 2023. The MPC Credit Agreement, among other 
things, provides for a $5.0 billion unsecured revolving credit facility that matures in July 2027 and letter of credit issuing capacity 
under the facility of up to $2.2 billion. Letters of credit issuing capacity is included in, not in addition to, the $5.0 billion borrowing 
capacity. The financial covenants of the MPC Credit Agreement are substantially the same as those contained in the previous 
credit agreement. 

The MPC Credit Agreement and trade receivables facility contain representations and warranties, affirmative and negative 
covenants and events of default that we consider usual and customary for agreements of these types. The financial covenant 
included in the MPC Credit Agreement 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 Agreement) 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, 2022, we were in compliance with the covenants contained in the MPC Credit Agreement and our 
trade receivables facility, including the financial covenant with a ratio of Consolidated Net Debt to Total Capitalization of 
approximately 0 to 1.00.

Our intention is to maintain an investment-grade credit profile. As of February 1, 2023, the credit ratings on our senior unsecured 
debt are as follows.

Company

MPC

Rating Agency

Rating

Moody’s

Baa2 (stable outlook)

Standard & Poor’s

BBB (stable outlook)

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

57

 
 
 
 
 
 
 
The MPC Credit Agreement does not contain 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, 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.

On March 14, 2022, MPLX issued $1.5 billion aggregate principal amount of 4.950% senior notes due March 2052 in an 
underwritten public offering. The net proceeds were used to repay amounts outstanding under the MPC intercompany loan 
agreement and under the previous MPLX credit agreement.

On July 7, 2022, MPLX entered into a new five-year revolving credit agreement (the “MPLX Credit Agreement”) to replace its 
previous $3.5 billion credit facility that was scheduled to expire in July 2024. The MPLX Credit Agreement, among other things, 
provides for a $2.0 billion unsecured revolving credit facility that matures in July 2027 and letter of credit issuing capacity under 
the facility of up to $150 million. Letters of credit issuing capacity is included in, not in addition to, the $2.0 billion borrowing 
capacity. The financial covenants of the MPLX Credit Agreement are substantially the same as those contained in the previous 
credit agreement. 

On August 11, 2022, MPLX issued $1.0 billion aggregate principal amount of 4.950% senior notes due September 2032 in an 
underwritten public offering. The net proceeds were used to redeem all of the $500 million aggregate principal amount of 3.500% 
senior notes due December 2022, $14 million of which was issued by Andeavor Logistics LP, and to redeem all of the 
$500 million aggregate principal amount of 3.375% senior notes due March 2023. 

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, 2022, MPLX was in compliance 
with the covenants, including the financial covenant with a ratio of Consolidated Total Debt to Consolidated EBITDA of 3.5 to 1.0.

Our intention is to maintain an investment-grade credit profile for MPLX. As of February 1, 2023, the credit ratings on MPLX’s 
senior unsecured debt are as follows.

Capital Requirements

Capital Spending

MPC’s capital investment plan for 2023 totals approximately $1.3 billion for capital projects and investments, excluding 
capitalized interest, potential acquisitions and MPLX’s capital investment plan. MPC’s 2023 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 for 
Midstream. 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 2023 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 $103 million, $68 million and $106 million for 2022, 2021 and 2020, respectively. The 2023 capital 
investment plan excludes capitalized interest.

The 2023 capital investment plan excludes reimbursable capital.

Refining & Marketing

The Refining & Marketing segment’s forecasted 2023 capital spending and investments is approximately $1.25 billion. This 
amount includes approximately $350 million of growth capital for low carbon projects, primarily the Martinez facility conversion 
and an emissions reduction project at our Los Angeles refinery. There is also $550 million of growth capital focused on traditional 
projects such as the STAR project and projects that we expect will help us reduce future operating costs and improve the 
competitive position of our assets. Maintenance capital is expected to be approximately $350 million which is essential to 
maintain the safety, integrity and reliability of our assets.

Major capital projects completed over the last three years have focused on refinery optimization, production of higher value 
products, increased capacity to upgrade residual fuel oil and expanded export capacity. We also focused on projects such as the 
Martinez facility conversion, the STAR project at our Galveston Bay refinery, which is scheduled to complete in the first half of 
2023, and projects expected to reduce future operating costs.

Midstream 

MPLX’s capital investment plan of $950 million, net of reimbursements, includes approximately $800 million of organic growth 
capital and $150 million of maintenance capital. MPLX’s growth capital plans are anchored in the Marcellus, Permian, and 
Bakken basins. In addition to new gas processing plants in the Marcellus and Permian, the remainder of MPLX’s capital plan is 
mostly focused on other investments targeted at the expansion or debottlenecking of existing assets to meet customer demand.

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.

Corporate and Other

The 2023 capital forecast includes approximately $50 million to support corporate and other activities. Major projects over the 
last three years included upgrades to information technology systems.

Share Repurchases

From January 1, 2012 through December 31, 2022, our board of directors has approved $35.05 billion in total share repurchase 
authorizations and we have repurchased a total of $31.72 billion of our common stock. As of December 31, 2022, MPC had 
$3.33 billion remaining under its share repurchase authorizations, which reflects the repurchase of 830,000 common shares for 
$96 million that settled in the first quarter of 2023. On January 31, 2023, we announced our board of directors approved an 
incremental $5.0 billion share repurchase authorization. The authorization has no expiration date. The table below summarizes 
our total share repurchases. See Item 8. Financial Statements and Supplementary Data – Note 11 for further discussion of the 
share repurchase plans.

Material Cash Commitments 

Contractual Obligations

We have purchase commitments primarily consisting of obligations to purchase and transport crude oil and feedstocks used in 
our refining operations. As of December 31, 2022, we had purchase obligations for crude oil, NGLs and renewable feedstocks of 
$23.11 billion, with $16.96 billion payable within 12 months, and crude oil transportation obligations of $6.19 billion, with $655 
million payable within 12 months. These contracts include variable price arrangements. For purposes of this disclosure, we have 
estimated prices to be paid primarily based on futures curves for the commodities to the extent available. Our contractual 
obligations do not include our contractual obligations to MPLX under various fee-based commercial agreements as these 
transactions are eliminated in the consolidated financial statements.

At December 31, 2022, we have non-cancelable obligations to acquire property, plant and equipment of $289 million, with $261 
million payable within 12 months. 

At December 31, 2022, we have aggregate principal amount of outstanding debt of $26.55 billion, with $1.0 billion payable within 
12 months, and interest on the debt of $16.70 billion, with $1.20 billion payable within 12 months. See Item 8. Financial 
Statements and Supplementary Data – Note 22 for additional information on our debt.

Our other contractual obligations primarily consist of finance and operating leases and pension and post-retirement obligations, 
for which additional information is included in Item 8. Financial Statements and Supplementary Data – Notes 28 and 26, 
respectively.

Other Cash Commitments

On January 27, 2023, we announced our board of directors approved a $0.75 per share dividend, payable March 10, 2023 to 
shareholders of record at the close of business on February 16, 2023.

We may, from time to time, repurchase our senior notes and preferred units 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.

TRANSACTIONS WITH RELATED PARTIES

See Item 8. Financial Statements and Supplementary Data – Note 9 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 GHG 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. Environmental remediation costs increased in 2022 compared to 2021 primarily due to a release of crude oil on 
an MPLX pipeline near Edwardsville, Illinois in March of 2022.

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 7 percent, 8 percent and 6 percent of capital expenditures, for 2022, 2021 
and 2020, respectively, excluding acquisitions. Our environmental capital expenditures are expected to be approximately $179 
million, or 8 percent, of total planned capital expenditures in 2023. 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.

62

•

•

•

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 the COVID-19 pandemic 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 macroeconomic environment are inherently subjective and 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. 

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.

At December 31, 2022, MPC had four reporting units with goodwill totaling approximately $8.24 billion. The majority of this 
balance is comprised of the Midstream reporting units, including $1.1 billion for the MPLX Crude Gathering reporting unit and 
$6.6 billion for the MPLX Transportation & Storage reporting unit. For the annual impairment assessment as of November 30, 
2022, management performed only a qualitative assessment for three reporting units as we determined it was more likely than 
not that the fair value of the reporting units exceeded the carrying value. Significant assumptions used to estimate the reporting 
units’ fair value under a qualitative approach included estimates of future cash flows and market information for comparable 
assets. A quantitative assessment was performed for the MPLX Crude Gathering reporting unit, which resulted in the fair value of 
the reporting unit exceeding its carrying value by greater than 10 percent. The fair value of the reporting unit was determined 
based on applying both a discounted cash flow method (i.e., income approach) as well as a market approach. An increase of one 
percentage point to the discount rate used to estimate the fair value of the reporting units would not have resulted in a goodwill 
impairment charge as of November 30, 2022. Significant assumptions that were used to estimate the Crude Gathering reporting 
unit’s 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. If estimates for future cash flows were to decline, the overall reporting units’ fair values would 
decrease, resulting in potential goodwill impairment charges. Fair value determinations require considerable judgment and are 
sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and 
assumptions made for purposes of the impairment tests will prove to be an accurate prediction of the future.

Equity Method 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. At 
December 31, 2022, we had $6.47 billion of investments in equity method investments recorded on our consolidated balance 
sheet. 

See Item 8. Financial Statements and Supplementary Data – Note 16 for additional information on our equity method 
investments. See Item 8. Financial Statements and Supplementary Data – Note 18 for additional information on our goodwill and 
intangibles, including a table summarizing our recorded goodwill by segment.

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 8.

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 indexes 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 from 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 $300 million par value outstanding.

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 5.10 percent 
for our pension plans and 5.00 percent for our other postretirement benefit plans by 0.25 percent would increase pension 
obligations and other postretirement benefit plan obligations by $64 million and $16 million, respectively, and would increase 
defined benefit pension expense and other postretirement benefit plan expense by $4 million and less than $1 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 

64

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 5.75 percent long-term rate of return to determine our 2022 defined benefit pension expense. After 
evaluating activity in the capital markets, along with the current and projected plan investments, we increased the asset rate of 
return for our primary plan to 7.00 percent effective for 2023. Decreasing the 6.00 percent asset rate of return assumption by 
0.25 percentage points would increase our defined benefit pension expense by $6 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 2021 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.

recently issued financial accounting pronouncements.

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, 2022, 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, swaps 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 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.

65

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 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, 2022 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.

Sensitivity analysis of the effect of a hypothetical 100-basis-point change in interest rates on long-term debt, including the portion 
classified as current and excluding finance leases, as of December 31, 2022 is provided in the following table. The fair value of 
cash and cash equivalents, receivables, accounts payable and accrued interest approximate carrying value and, in addition to 
short-term investments which are recorded at fair value, are relatively insensitive to changes in interest rates due to the short-
term maturity of the instruments. Accordingly, these instruments are excluded from the table.

See Item 8. Financial Statements and Supplementary Data – Note 20 for additional information on the fair value of 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 and some of our sales of finished products denominated in Mexican pesos. We did not use derivatives to hedge our 
market risk exposure to these foreign exchange rate fluctuations in 2022. 

Counterparty Risk 

MPLX is subject to risk of loss resulting from nonpayment by its customers to whom it provides services, leases assets, or sells 
natural gas or NGLs. MPLX believes that certain contracts where it sells NGLs and acts as its producer customers’ agent would 
allow it to pass those losses through to its customers, thus reducing its risk, when it is selling NGLs and acting as its producer 
customers’ agent. Its credit exposure related to these customers is represented by the value of its trade receivables or lease 
receivables. Where exposed to credit risk, MPLX analyzes the customer’s financial condition prior to entering into a transaction 
or agreement, establishes credit terms and monitors the appropriateness of these terms on an ongoing basis. In the event of a 
customer default, MPLX may sustain a loss and its 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, 
2022.

The effectiveness of MPC’s internal control over financial reporting as of December 31, 2022 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, 2022 and 2021, 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, 
2022, 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, 2022, 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, 2022 and 2021, and the results of its operations and its cash flows for each of the three 
years in the period ended December 31, 2022 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, 2022, 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 matter communicated below is a matter arising from the current period audit of the consolidated financial 
statements that was communicated or required to be communicated to the audit committee and that (i) relates 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 matter below, providing a separate 
opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Goodwill Impairment Test - Crude Gathering Reporting Unit

As described in Note 18 to the consolidated financial statements and as disclosed by management, the Company’s consolidated 
goodwill balance was $8.2 billion as of December 31, 2022, which includes, within the Midstream segment, the goodwill 
associated with MPLX’s Crude Gathering reporting unit of $1.1 billion. 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 fair value of the MPLX Crude Gathering reporting unit was 
determined based on applying both a discounted cash flow method (i.e. income approach) as well as a market approach. 
Significant assumptions that were used to estimate the reporting unit’s fair value 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 test of the 
Crude Gathering reporting unit of the Midstream segment is a critical audit matter are (i) the significant judgment by management 
when determining the fair value of the reporting unit; and (ii) the high degree of auditor judgment, subjectivity, and effort in 
performing procedures and evaluating audit evidence relating to 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 test, including controls over the determination of the fair value of the Crude Gathering 
reporting unit. These procedures also included, among others (i) testing management’s process for determining the fair value of 
the reporting unit; (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. Evaluating the assumption related to future volumes involved (i) considering 
whether the assumption used was reasonable considering past performance of the 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.

Notes to Consolidated Financial Statements

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 branded outlets. We also sell transportation fuel to consumers 
through 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 May 14, 2021, we completed the sale of Speedway, our company-owned and operated retail transportation fuel and 
convenience store business, to 7-Eleven, Inc. (“7-Eleven”). Speedway’s results are reported separately as discontinued 
operations, net of tax, in our consolidated statements of income for all periods presented. 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. 

Refer to Notes 6 and 12 for additional information about our operations.

Basis of Presentation 

All significant intercompany transactions and accounts have been eliminated.

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 revenues, since 
we continue to supply fuel to Speedway subsequent to the sale to 7-Eleven. All periods presented have been retrospectively 
adjusted through the sale date of May 14, 2021 to reflect this change. Additionally, from August 2, 2020 through May 14, 2021, in 
accordance with ASC 360, Property, Plant, and Equipment, we ceased recording depreciation and amortization for Speedway’s 
PP&E, finite-lived intangible assets and right of use lease assets.

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, 2022, we owned the general partner and approximately 65 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. Actual results could differ from those estimates.

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. 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. 

78

   
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 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 12 for a description of our 
reportable segment operations.

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.

Short-Term Investments

Investments with a maturity date greater than three months that we intend to convert to cash or cash equivalents within a year or 
less are classified as short-term investments in our consolidated balance sheets. Additionally, in accordance with ASC 320, 
Investments - Debt Securities, we have classified all short-term investments as available-for-sale securities and changes in fair 
market value are reported in other comprehensive income.

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 150 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.

As a lessor under ASU No. 2016-02, Leases (“ASC 842”), MPLX may be required to re-classify existing operating leases to 
sales-type leases upon modification and related reassessment of the leases. See Note 28 for further information regarding our 
ongoing evaluation of the impacts of lease reassessments as modifications occur. The net investment in sales-type leases is 
recorded within receivables, net and other noncurrent assets on the consolidated balance sheets. These amounts are comprised 
of the present value of the sum of the future minimum lease payments representing the value of the lease receivable and the 
unguaranteed residual value of the lease assets. Management assesses the net investment in sales-type leases for 
recoverability quarterly.

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.

Fair Value

We account for certain assets and liabilities at fair value. The hierarchy below lists three levels of fair value based on the extent 
to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in 
one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These 
levels are:

•

•

•

Level 1 – inputs are based upon unadjusted quoted prices for identical instruments in active markets. Our Level 1 
derivative assets and liabilities include 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.

Level 2 – inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or 
similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs 
are observable in the market or can be corroborated by observable market data for substantially the full term of the 
assets or liabilities. Where applicable, these models project future cash flows and discount the future amounts to a 
present value using market-based observable inputs including interest rate curves, credit spreads, and forward and spot 
prices for currencies. Our Level 2 investments include commercial paper, certificates of deposit, time deposits and 
corporate notes and bonds. Our Level 2 derivative assets and liabilities primarily include certain OTC contracts.

Level 3 – inputs are generally unobservable and typically reflect management’s estimates of assumptions that market 
participants would use in pricing the asset or liability. The fair values are therefore determined using model-based 
techniques, including option pricing models and discounted cash flow models. Our Level 3 assets and liabilities include 
goodwill, long-lived assets and intangible assets, when they are recorded at fair value due to an impairment charge and 
an embedded derivative liability relates to a natural gas purchase agreement embedded in a keep-whole processing 
agreement. Unobservable inputs used in the models are significant to the fair values of the assets and liabilities.

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.

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 their financial strength and on credit ratings, if 
available. Additionally, we limit the level of exposure with any single counterparty.

80

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, generally 10 to 40 years for refining and midstream assets, 25 years for office buildings and 4 to 7 years for other 
miscellaneous fixed assets. 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 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.

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.

81

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.

Share-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.

Our share-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 share-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 deficiency 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 state programs, 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 assets or other noncurrent assets on the consolidated 
balance sheets, 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 liabilities or deferred credits and other liabilities 
on the consolidated balance sheets, 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 consolidated statements of income. Any gains 
or losses on the sale or expiration of allowances or credits are classified as other income on the consolidated statements of 
income. Proceeds from the sale of allowances or credits are reported in investing activities - all other, net on the consolidated 
statements of cash flow.

short term and highly liquid securities.

Unrealized losses on debt investments held from May 14, 2021, which coincides with the sale of Speedway, to December 31, 
2022 were not material. Realized gains/losses were not material. All of our available-for-sale debt securities held as of 
December 31, 2022 mature within one year or less or are readily available for use.

5.   Discontinued Operations 

On May 14, 2021, we completed the sale of Speedway, our company-owned and operated retail transportation fuel and 
convenience store business, to 7-Eleven for cash proceeds of approximately $21.38 billion. After-tax proceeds were 
approximately $17.22 billion. This transaction resulted in a pretax gain of $11.68 billion ($8.02 billion after income taxes) after 
deducting the book value of the net assets and certain other adjustments.

The transaction provided for adjustments for working capital and other miscellaneous items, which were finalized with 7-Eleven 
in the fourth quarter of 2022, resulting in an additional pretax gain of $60 million.

Fuel Supply Agreements

During the second quarter of 2021, we entered into various 15-year fuel supply agreements through which we continue to supply 
fuel to Speedway. 

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, 2022, we owned approximately 65 percent of the 
outstanding MPLX common units. 

Unit Repurchase Program

On November 2, 2020, MPLX announced the board authorization of a unit repurchase program for the repurchase of up to 
$1.0 billion of MPLX’s outstanding common units held by the public, which was exhausted during the fourth quarter of 2022. On 
August 2, 2022, MPLX announced its board of directors approved an incremental $1.0 billion unit repurchase authorization. The 
unit repurchase authorizations have no expiration date. MPLX may utilize various methods to effect the repurchases, which could 
include open market repurchases, negotiated block transactions, accelerated unit repurchases, tender offers or open market 
solicitations for units, some of which may be effected through Rule 10b5-1 plans. The timing and amount of future repurchases, if 
any, will depend upon several factors, including market and business conditions, and such repurchases may be discontinued at 
any time.

Total unit repurchases were as follows for the respective periods:

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 effected 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.

Series B Preferred Units

As of December 31, 2022, MPLX had 600,000 preferred units (“Series B preferred units) representing limited partner interests of 
MPLX and having a liquidation value of $1,000 per unit. On February 15, 2023, MPLX exercised its right to redeem all of the 
Series B preferred units at the redemption price of $1,000 per unit.

The Series B preferred units are included in noncontrolling interests on our consolidated balance sheets.

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, 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 were as follows:

Impairments 

During 2021, we recognized $69 million of impairment expense within our Midstream segment related to the divestiture, 
abandonment or closure of certain assets as detailed in the table below.

During the first quarter of 2020, the outbreak of COVID-19 caused 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 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, along with the location of these impairments within 
the consolidated statements of income.

Goodwill

During the first quarter of 2020, we recorded an impairment of goodwill of $7.33 billion. The goodwill impairment within the 
Refining & Marketing segment was primarily driven by the effects of the COVID-19 pandemic 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 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.

Equity Method Investments

During the first quarter of 2020, we recorded equity method investment impairment charges totaling $1.32 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.

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 the COVID-19 pandemic 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.

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. 

86

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. The facility is expected to ramp up to producing 730 million 
gallons per year by the end of 2023, with pretreatment capabilities coming online in 2023. As a result of the progression of these 
activities, we identified assets that would be repurposed and utilized in a renewable diesel facility configuration and assets that 
would be abandoned since they had no function in a renewable diesel facility configuration. This change in our intended use for 
the Martinez refinery is a long-lived asset impairment trigger for the assets that would be repurposed and remain as part of the 
Martinez asset group. We assessed the asset group for impairment by comparing the undiscounted estimated pretax cash flows 
to the carrying value of the asset group and the undiscounted estimated pretax cash flows exceeded the Martinez asset group 
carrying value. We recorded impairment expense of $342 million for the abandoned assets as we are no longer using these 
assets and have no expectation to use these assets in the future. Additionally, as a result of our efforts to progress the 
conversion of Martinez refinery into a renewable diesel facility, MPLX cancelled in-process capital projects related to its Martinez 
refinery logistics operations resulting in impairments of $27 million in the third quarter 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, MPLX 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 the COVID-19 pandemic. The cash flows associated with these assets were significantly impacted by 
volume declines reflecting decreased forecasted producer customer production as a result of lower commodity prices. MPLX 
assessed each asset group within the Western G&P reporting unit for impairment. It was determined that the fair value of the 
East Texas G&P asset group’s underlying assets were less than the carrying value. As a result, MPLX recorded impairment 
charges totaling $350 million related to its property, plant and equipment and intangibles, which are included in impairment 
expense on our consolidated statements of income. Fair value of property, plant and equipment was determined using a 
combination of an income and cost approach. The income approach utilized significant assumptions including management’s 
best estimates of the expected future cash flows and the estimated useful life of the asset group. The cost approach utilized 
assumptions for the current replacement costs of similar assets adjusted for estimated depreciation and deterioration of the 
existing equipment and economic obsolescence. The fair value of the intangibles was determined based on applying the multi-
period excess earnings method, which is an income approach. Key assumptions included management’s best estimates of the 
expected future cash flows from existing customers, customer attrition rates and the discount rate. Fair value determinations 
require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no 
assurance that the estimates and assumptions made for purposes of the impairment analysis will prove to be an accurate 
prediction of the future. The fair value measurements for the asset group fair values represent Level 3 measurements.

8.  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.

On September 21, 2022, MPC closed on the formation of the Martinez Renewable Fuels joint venture (the “Martinez Renewable 
joint venture”) with Neste Corporation (“Neste”). We determined that, as of the closing date, Martinez Renewables LLC is a VIE 
because the entity does not have sufficient equity to complete the modification of the plant to produce renewable fuels without 
additional financial support from its owners. 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. 

Capline LLC

Capline LLC is unable to fund its operations without financial support from its equity owners and is a VIE. Our maximum 
exposure to loss as a result of our involvement with Capline LLC includes our equity method 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. 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.

Crowley Coastal Partners

We have determined that Crowley Coastal Partners LLC (“Crowley Coastal Partners”) is a VIE based on the terms of the existing 
financing arrangement for Crowley Blue Water Partners LLC (“Crowley Blue Water Partners”) and the associated debt guarantee 
by MPC and Crowley Maritime Corporation. Our maximum exposure to loss includes our equity method investment in Crowley 
Coastal Partners and the debt guarantees provided to each of the lenders to Crowley Blue Water 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 LLC (“Sherwood Midstream”) has been deemed the primary beneficiary of Sherwood Midstream Holdings 
LLC (“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 16 for ownership 
percentages and investment balances and Note 29 for our exposure to guarantees 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. 

10.  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 share-based compensation awards, provided the effect is not anti-dilutive.

11.  Equity 

We announced our board of directors approved a $5.0 billion share repurchase authorization on February 2, 2022, which was 
exhausted during the fourth quarter of 2022, and an additional $5.0 billion share repurchase authorization on August 2, 2022. 
These authorization have no expiration date. 

We may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block 
transactions, tender offers, accelerated share repurchases or open market solicitations for shares, some of which may be 
effected through Rule 10b5-1 plans. The timing and amount of future repurchases, if any, will depend upon several factors, 
including market and business conditions, and such repurchases may be suspended or discontinued at any time.

Total share repurchases were as follows for the respective periods:

As of December 31, 2022, MPC had $3.33 billion remaining under its share repurchase authorizations, which reflects the 
repurchase of 830,000 common shares for $96 million that settled in the first quarter of 2023. 

12.  Segment Information 

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, including renewable 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, including renewable diesel, 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 and through long-term fuel supply contracts with direct dealers who operate locations mainly 
under the ARCO® brand. 

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

90

 
 
 
 
 
 
 
 
 
 
 
 
During the first quarter of 2022, our chief operating decision maker (“CODM”) began to evaluate the performance of our 
segments using segment adjusted EBITDA. We have modified our presentation of segment performance to be consistent with 
this change, including prior periods presented for consistent and comparable presentation. Amounts included in income (loss) 
from continuing operations before income taxes and excluded from adjusted EBITDA include: (i) depreciation and amortization; 
(ii) net interest and other financial costs; (iii) turnaround expenses and (iv) other adjustments as deemed necessary. These items 
are either: (i) believed to be non-recurring in nature; (ii) not believed to be allocable or controlled by the segment; or (iii) not tied 
to the operational performance of the segment. 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.

Since we will continue to supply fuel to Speedway subsequent to the sale to 7-Eleven, we have reported intersegment sales to 
Speedway, that were previously eliminated in consolidation, as third-party sales. All periods presented have been retrospectively 
adjusted through the sale date of May 14, 2021 to reflect this change. Sales to Speedway/7-Eleven from the Refining & 
Marketing segment represented 10 percent, 11 percent and 11 percent of our total annual revenues for the years ended 
December 31, 2022, 2021 and 2020, respectively. See Note 23 for the disaggregation of our revenue by segment and product 
line.

Our effective tax rate for the year ended December 31, 2022 was higher than the tax computed at the U.S. statutory rate 
primarily due to state taxes, partially offset by permanent tax benefits related to net income attributable to noncontrolling 
interests.

Our effective tax rate for the year ended December 31, 2021 was lower than the tax computed at the U.S. statutory rate primarily 
due to permanent tax benefits related to net income attributable to noncontrolling interests and an increase in benefit related to 
the net operating loss (“NOL”) carryback provided under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), 
partially offset by state taxes and local income taxes.

Our effective income tax benefit rate for the year ended December 31, 2020 was lower than the tax benefit computed at the U.S. 
statutory rate due to a significant amount of our pre-tax loss consisting of non-deductible goodwill impairment charges, partially 
offset by the tax rate differential resulting from the NOL carryback provided under the CARES Act. Additionally, our non-
controlling interest in MPLX generally provides an effective tax rate benefit since the tax associated with these ownership 
interests is paid by those interests, but this benefit was lower for the year ended December 31, 2020 due to impairment charges 
recorded by MPLX.

On March 27, 2020, the 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 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 realized a cumulative income tax benefit of 
$2.30 billion. We received $1.55 billion of the income tax benefit in cash during the fourth quarter of 2021, an additional 
$690 million was realized as an offset to 2021 income tax liability payment obligations and we expect to receive the remaining 
$59 million refund during 2023.

At both December 31, 2022 and 2021, federal operating loss carryforwards were $4 million, which includes a mix of indefinite 
carryforward ability and expiration periods ranging from 2032 through 2037. As of December 31, 2022 and 2021, state and local 
operating loss and tax credit carryforwards were $40 million and $128 million, respectively, which includes a mix of indefinite 
carryforward ability and expiration periods ranging from 2023 through 2040. As of December 31, 2022 and 2021, foreign 
operating loss carryforwards were $20 million and $9 million, respectively, which includes expiration periods ranging from 2029 
through 2043.

As of December 31, 2022 and 2021, $49 million and $38 million of valuation allowances have been recorded related to income 
taxes, primarily related to realizability foreign tax operating losses and related deferred tax assets. 

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. During the fourth quarter of 2021, an IRS audit was initiated for MPLX and its subsidiaries for the tax 
year 2019 and continued during 2022. We do not believe the eventual outcome of such audit will have a material impact on our 
financial statements as of December 31, 2022.

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, 2022, we have various state and local income tax returns subject to 
examination for years 2006 through 2021, depending on jurisdiction.

If the unrecognized tax benefits as of December 31, 2022 were recognized, $49 million would affect our effective income tax rate. 
There were $29 million of uncertain tax positions as of December 31, 2022 for which it is reasonably possible that the amount of 
unrecognized tax benefits would significantly decrease during the next twelve months.

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 $1 million, $(2) million and $(19) million in 2022, 2021 and 2020, respectively. As of 
December 31, 2022 and 2021, $4 million and $6 million of interest and penalties receivables (payables) were accrued related to 
income taxes, respectively.

The LIFO method accounted for 88 percent of total inventory value at both December 31, 2022 and 2021. Current acquisition 
costs were estimated to exceed the LIFO inventory value by $3.72 billion as of December 31, 2022. There was $2.84 billion 
excess of replacement or current cost over our stated LIFO cost at December 31, 2021.

The cost of inventories of crude oil and refined products is determined primarily under the LIFO method.

16.  Equity Method Investments 

Crowley Ocean Partners

Crowley Coastal Partners was formed in May 2016 to own both Crowley Ocean Partners LLC (“Crowley Ocean Partners”) and 
Crowley Blue Waters Partners. MPC accounts for our 50 percent ownership in Crowley Coastal Partners as an equity method 
investment.

On December 1, 2022, MPC purchased all of Crowley Coastal Partner’s interest in Crowley Ocean Partners and its four 
subsidiaries for approximately $485 million, which included $196 million to pay off the debt associated with the four tankers. As a 
result of the transaction, Crowley Ocean Partners is now included in our consolidated results. MPC will continue to account for its 
50 percent interest in Crowley Coastal Partners as an equity method investment. 

The excess of the $144 million fair value over the $125 million book value of our 50 percent indirect interest in Crowley Ocean 
Partners resulted in a $19 million gain, which is included in the income (loss) from equity method investments line of the 
accompanying consolidated statements of income.

Martinez Renewables LLC

On September 21, 2022, MPC closed on the formation of the Martinez Renewable joint venture. MPC contributed property, plant 
and equipment, inventory, and working capital with an estimated fair value of $1.47 billion and Neste contributed $728 million in 
cash. MPC recorded a non-cash gain of $549 million resulting from the difference between the carrying value and fair value of 
the contributed property, plant and equipment and inventory. Subsequent to the closing, the joint venture paid a special 
distribution to MPC of $500 million, which is reflected as a return of capital in MPC’s consolidated statements of cash flows. After 
the special distribution, MPC’s investment value in the entity was approximately $971 million. We apply the equity method of 
accounting with respect to our investment in the entity.

Watson Cogeneration Company

On June 1, 2022, MPC purchased the remaining 49 percent interest in Watson Cogeneration Company from NRG Energy, Inc. 
for approximately $59 million. This entity is now consolidated and included in our consolidated results. It was previously 
accounted for as an equity method investment.

The excess of the $62 million fair value over the $25 million book value of our 51 percent ownership interest in Watson 
Cogeneration Company resulted in a $37 million non-cash gain, which is included in the net gain on disposal of assets line of the 
accompanying consolidated statements of income.

As of December 31, 2022, the carrying value of our equity method investments was $304 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 $208 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 $772 million, $652 million and $577 million in 2022, 2021 and 2020, respectively.

18.  Goodwill and Intangibles 

Goodwill

MPC 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. There were 
no impairments of goodwill required based on our annual test of goodwill in 2022 and 2021.

At December 31, 2022, MPC had four reporting units with goodwill totaling approximately $8.24 billion. For the annual 
impairment assessment as of November 30, 2022, management performed only a qualitative assessment for three reporting 
units as we determined it was more likely than not that the fair value of the reporting units exceeded the carrying value. A 
quantitative assessment was performed for the remaining reporting unit, which resulted in the fair value of the reporting unit 
exceeding its carrying value by greater than 10 percent.

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

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 remaining exit and disposal costs reserve to occur through 2024.

Represents the impact of netting assets, liabilities and cash collateral when a legal right of offset exists. As of December 31, 2022, cash 
collateral of $58 million was netted with mark-to-market liabilities. As of December 31, 2021, cash collateral of $14 million was netted with 
mark-to-market derivative liabilities.

Level 3 instruments relate to an embedded derivative liability for a natural gas purchase commitment embedded in a keep-whole 
processing agreement. The fair value calculation for these Level 3 instruments at December 31, 2022 used significant 
unobservable inputs including: (1) NGL prices interpolated and extrapolated due to inactive markets ranging from $0.68 to $1.62 
per gallon with a weighted average of $0.84 per gallon and (2) the probability of renewal of 100 percent for the 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. 

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

Non-recurring fair value measurements and disclosures relate primarily to sales-type leases discussed in Note 28 and the 
Martinez Renewables LLC equity method investment discussed in Note 16. The net investment in sales-type leases was 
recorded at the estimated fair value of the underlying leased assets at contract modification date. The leased assets were valued 
using a cost method valuation approach which utilizes Level 3 inputs. The fair value of the Martinez Renewables LLC equity 
method investment was primarily based on the cash consideration received from Neste for their 50 percent ownership.

Fair Values – Reported

We believe the carrying value of our other financial instruments, including cash and cash equivalents, receivables, accounts 
payable and certain accrued liabilities, approximate fair value. Our fair value assessment incorporates a variety of 
considerations, including the short-term duration of the instruments and the expected insignificance of bad debt expense, which 
includes an evaluation of counterparty credit risk. The borrowings under our revolving credit facilities, which include variable 
interest rates, approximate fair value. The fair value of our 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 $26.3 billion and 
$24.0 billion at December 31, 2022, respectively, and approximately $25.1 billion and $28.1 billion at December 31, 2021, 
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, 2022 and 2021 and the line items in the 
consolidated 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 March 1, 2021, we repaid the $1.0 billion outstanding aggregate principal amount of 5.125% senior notes due March 2021.

In June 2021, all of the $300 million outstanding aggregate principal amount of 5.125% senior notes due April 2024, including the 
portion of such notes for which Andeavor was the obligor, were redeemed at a price equal to 100.854% of the principal amount, 
plus accrued and unpaid interest to, but not including, the redemption date.

On December 2, 2021, all of the $1.25 billion outstanding aggregate principal amount 4.5% senior notes due May 2023 and the 
$850 million outstanding aggregate principal amount of 4.75% senior notes due December 2023, including the portion of such 
notes for which Andeavor was the obligor, were redeemed at a price equal to par, plus a make-whole premium and accrued and 
unpaid interest to, but not including, the redemption date. The payment of $132 million related to the note premium, offset by the 
immediate expense recognition of $6 million of unamortized debt premium and issuance costs, resulted in a loss on 
extinguishment of debt of $126 million.

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 and MPLX. 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.

On March 14, 2022, MPLX issued $1.5 billion aggregate principal amount of 4.950% senior notes due March 2052 in an 
underwritten public offering. The net proceeds were used to repay amounts outstanding under the MPC intercompany loan 
agreement and under the previous MPLX credit agreement.

On August 11, 2022, MPLX issued $1.0 billion aggregate principal amount of 4.950% senior notes due September 2032 in an 
underwritten public offering. The net proceeds were used to redeem all of the $500 million aggregate principal amount of 3.500% 
senior notes due December 2022, $14 million of which was issued by Andeavor Logistics LP, and to redeem all of the 
$500 million aggregate principal amount of 3.375% senior notes due March 2023. 

2021 Activity

On January 15, 2021, MPLX redeemed 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, at a price equal to 102.625% of the principal amount, plus 
accrued and unpaid interest to, but not including, the redemption date.

On September 3, 2021, MPLX redeemed, at par value, all of the $1.0 billion aggregate principal amount of floating rate senior 
notes due September 2022, plus accrued and unpaid interest to, but not including, the redemption date. MPLX primarily funded 
the redemption with borrowings under the MPC intercompany loan agreement.

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.

The committed borrowing and letter of credit issuance capacity of the trade receivables securitization facility is $100 million. In addition, the 
facility allows for the issuance of letters of credit in excess of the committed capacity at the discretion of the issuing banks. As of 
December 31, 2022, letters of credit in the total amount of $1.05 billion were issued and outstanding under the facility to secure contracts 
awarded by the Department of Energy to purchase crude oil from the Strategic Petroleum Reserve.

MPC Bank Revolving Credit Facility

On July 7, 2022, MPC entered into a new five-year revolving credit agreement (the “MPC Credit Agreement”) to replace its 
previous $5.0 billion credit facility that was scheduled to expire in October 2023. The MPC Credit Agreement, among other 
things, provides for a $5.0 billion unsecured revolving credit facility that matures in July 2027 and letter of credit issuing capacity 
under the facility of up to $2.2 billion. Letters of credit issuing capacity is included in, not in addition to, the $5.0 billion borrowing 
capacity. The financial covenants of the MPC Credit Agreement are substantially the same as those contained in the previous 
credit agreement.

MPC has an option under the MPC 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, the maturity 
date may be extended, for up to two additional one year periods, subject to, among other conditions, the approval of lenders 
holding the majority of the commitments then outstanding, provided that the commitments of any non-consenting lenders will 
terminate on the then-effective maturity date. The MPC 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 Agreement bear interest, at our election, at either the Adjusted Term SOFR or the Alternate 
Base Rate, both as defined in the MPC Credit Agreement, plus an applicable margin. We are 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 MPC Credit Agreement fluctuate based on changes, if any, to our credit 
ratings.

The MPC Credit Agreement contains 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 Agreement, 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, 2022, we were in compliance with the covenants contained in the MPC Credit Agreement. 

Trade Receivables Securitization Facility 

On September 30, 2021, we entered into a Loan and Security Agreement and related documentation with a group of lenders 
providing for a new trade receivables securitization facility having $100 million of committed borrowing and letter of credit 
issuance capacity and up to an additional $400 million of uncommitted borrowing and letter of credit issuance capacity that can 
be extended at the discretion of the lenders, provided that at no time may outstanding borrowings and letters of credit issued 
under the facility exceed the balance of eligible trade receivables (as calculated in accordance with the Loan and Security 
Agreement) that are pledged as collateral under the facility. In July 2022, the trade receivables securitization facility was 
amended to, among other things, extend its term until September 29, 2023.

The trade receivables facility consists of certain of our wholly owned subsidiaries (“Originators”) selling or contributing on an on-
going basis all of the trade receivables generated by them (the “Pool 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 I LLC (“TRC”), in exchange for a combination of cash, equity and/or borrowings under a 
subordinated note issued by TRC. TRC may request borrowings and extensions of credit under the Loan and Security 
Agreement for up to the lesser of the maximum capacity under the facility or the eligible trade receivables balance of the Pool 
Receivables. TRC and each of the Originators have granted a security interest in all of their rights, title and interests in and to the 

105

 
 
 
 
 
 
 
Pool Receivables, together with all related security and interests in the proceeds thereof, to the lenders to secure the 
performance of TRC’s and the Originators’ payment and other obligations under the facility. In addition, MPC has issued a 
performance guaranty in favor of the lenders guaranteeing the performance by TRC and the Originators of their obligations under 
the facility.

To the extent that TRC retains an ownership interest in the Pool Receivables, 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 lenders to secure its obligations 
under the Loan and Security Agreement.

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 Loan and Security Agreement and other documents comprising the facility 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 be eligible receivables that count towards the borrowing base under the trade receivables 
facility. In addition, the lender’s commitments to extend loans and credits under the facility are subject to termination, and TRC 
may be subject to default fees, upon the occurrence of certain events of default that are included in the Loan and Security 
Agreement and other facility documentation, all of which we consider to be usual and customary for arrangements of this type. 
As of December 31, 2022, we were in compliance with the covenants contained in the Loan and Security Agreement and other 
facility documentation.

MPLX Bank Revolving Credit Facility 

On July 7, 2022, MPLX entered into a new five-year revolving credit agreement (the “MPLX Credit Agreement”) to replace its 
previous $3.5 billion credit facility that was scheduled to expire in July 2024. The MPLX Credit Agreement, among other things, 
provides for a $2.0 billion unsecured revolving credit facility that matures in July 2027 and letter of credit issuing capacity under 
the facility of up to $150 million. Letters of credit issuing capacity is included in, not in addition to, the $2.0 billion borrowing 
capacity. 

The borrowing capacity under the MPLX Credit Agreement 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. In addition, the maturity date may be 
extended, for up to two additional one year periods, subject to, among other conditions, the approval of lenders holding the 
majority of the commitments then outstanding, provided that the commitments of any non-consenting lenders will terminate on 
the then-effective maturity date.

Borrowings under the MPLX Credit Agreement bear interest, at MPLX’s election, at either the Adjusted Term SOFR 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, 2022, 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 $2,272 million and $2,995 million as of 
December 31, 2022 and 2021.

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 2022, 2021 and 2020 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 2022, 2021 and 2020.

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 

111

 
 
 
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, 2022, 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, 2022 and 2021.

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”) 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, while Level 2 include derivative transactions.

Cash Flows

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 2022, we made contributions totaling $15 million to our funded 
pension plans. For 2023, we do not project any required funding, but we may make voluntary contributions to our funded pension 
plans at our discretion. Cash contributions to be paid from our general assets for the unfunded pension and postretirement plans 
are estimated to be approximately $7 million and $50 million, respectively, in 2023.

We also contribute to a defined contribution plan for eligible employees. Contributions to this plan totaled $167 million, $165 
million and $180 million in 2022, 2021 and 2020, 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 2022, 2021 and 2020 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 2022 and 2021 is for the 
plan’s year ended December 31, 2021 and December 31, 2020, 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 2022, 2021 and 2020 contributions. Our portion 
of the contributions does not make up more than five percent of total contributions to the plan.

(a)

This agreement has a minimum contribution requirement of $338 per week per employee for 2023. A total of 258 employees participated in 
the plan as of December 31, 2022.

Multiemployer Health and Welfare Plan

We contribute to one multiemployer health and welfare plan that covers both active employees and retirees. Through the health 
and welfare plan, employees receive medical, dental, vision, prescription and disability coverage. Our contributions to this plan 
totaled $7 million, $7 million and $7 million for 2022, 2021 and 2020, respectively.

27.  Share-Based Compensation 

Description of the Incentive Plans

Our employees and non-employee directors are eligible to receive share, share-based and other types of awards under the 
Marathon Petroleum Corporation 2021 Incentive Compensation Plan (“MPC 2021 Plan”). The MPC 2021 Plan authorizes the 
Compensation and Organization Development Committee of our board of directors (“Committee”) to grant nonqualified or 
incentive stock options, stock appreciation rights, share and share-based awards (including restricted stock and restricted stock 

114

 
 
 
 
 
 
 
 
 
 
 
 
unit awards), cash awards and performance awards to our employees and non-employee directors. The maximum number of 
shares of our common stock available for awards under the MPC 2021 Plan is 20.5 million shares. The MPC 2021 Plan became 
effective upon shareholder approval on April 28, 2021. Prior to that date, our employees and non-employee directors were 
eligible to receive share, share-based and other types of awards under the Amended and Restated Marathon Petroleum 
Corporation 2012 Incentive Compensation Plan (“MPC 2012 Plan”), effective April 26, 2012, and prior to that date, the Marathon 
Petroleum Corporation 2011 Second Amended and Restated Incentive Compensation Plan (“MPC 2011 Plan”). Shares issued as 
a result of awards granted under these plans are funded through the issuance of new MPC common shares.

Share-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 

Prior to 2021, we granted stock options to certain officer and non-officer employees under the MPC 2011 Plan and the MPC 
2012 Plan. Stock options represent the right to purchase shares of our common stock at an exercise price equal to the closing 
price of our common stock on the date of grant. Stock options generally vest over a  service period of three years and expire ten 
years after the grant date. We used 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 units to certain employees and to our non-employee directors. Prior to 2021, we granted restricted 
stock to certain employees and to our 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 awards and restricted stock unit awards granted 
to officers prior to 2022 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. 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. The fair values of restricted stock and restricted stock units are equal to the market price of our common stock on 
the grant date.

Performance Units and Performance Share Units 

We grant performance share unit awards to certain officer employees. At grant, a performance share unit has a target value 
equal to the MPC common stock average 30-day closing price prior to the grant date. The actual payout value of a performance 
share unit is based on company performance (which can range from 0% to 200%) during the three calendar year period 
beginning in the year of grant, multiplied by MPC’s closing share price on the date the Committee certifies performance. 
Performance share units have a vesting service period beginning on the grant date and ending on the last day of the three-year 
performance period. Company performance for purposes of payout will be determined by the relative ranking of the total 
shareholder return (“TSR”) of MPC common stock over the three-year performance period compared to the TSR of a select 
group of peer companies and the Standard & Poor’s 500 Index and the Alerian MLP Index over the performance period, as well 
as the median of MPC’s compensation reference group. These awards settle 100 percent in cash and are accounted for as 
liability awards and recorded at fair value with a mark-to-market adjustment made each quarter.

We also grant performance share unit awards to certain non-officer employees. These performance share unit awards operate 
as explained above for awards made to certain officer employees, but the awards vest in one-third increments on December 31 
of the first, second and third calendar years of the three calendar year performance period.

No performance share unit awards were granted prior to 2021. Prior to 2021, we granted performance unit awards to certain 
officer employees under the MPC 2012 Plan. 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 unit awards have a 36-month 
requisite service period. The payout value of these awards is determined by the relative ranking of the 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 are settled 25 percent in MPC common stock and 75 percent in cash. 
The number of shares actually distributed is determined as 25 percent of the final payout divided 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 
share awards and do not receive dividend equivalents.

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.

MPLX Awards

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 96 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 is considered to be the lessor under several operating lease agreements in accordance with GAAP related to certain fee-
based natural gas transportation and processing agreements in the Marcellus and Southern Appalachia region. The primary term 
of these agreements expire between 2026 and 2036, however, these contracts either have renewal options or 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. 
MPLX elected the practical expedient to carry forward historical classification conclusions until a modification of an existing 
agreement occurs. Once a modification occurs, the amended agreement is required to be assessed under ASC 842 to determine 
whether a reclassification of the lease is required.

During the third quarter of 2022, the approved expansion of a gathering and compression system triggered the first assessment 
of a third party agreement under ASC 842. As a result of the assessment during the period, the lease was reclassified from an 
operating lease to a sales-type lease. Accordingly, the underlying property, plant and equipment of $745 million and associated 
deferred revenue of $277 million were derecognized. The present value of the future lease payments of $914 million and the 
unguaranteed residual value of $63 million were recorded as the net investment in the lease within receivables and other 
noncurrent assets. This resulted in a gain of approximately $509 million, which was recorded as a net gain on disposal of assets 
in the consolidated statements of income. This transaction was a non-cash transaction.

Lease revenues are included in sales and other operating revenues on the consolidated statements of income. Lease revenues 
were as follows:

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, 2022 and 2021, accrued liabilities for remediation totaled $387 million and $401 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 $5 million and $6 
million at December 31, 2022 and 2021, respectively.

Governmental and other entities in various states have filed climate-related lawsuits against numerous 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 $27 million and $14 million at December 31, 2022 and 2021, respectively, and 
are included in other current liabilities in our consolidated balance sheets. Our long-term asset retirement obligations were $186 
million and $187 million at December 31, 2022 and 2021, respectively, which are included in deferred credits and other liabilities 
in our consolidated balance sheets. 

Other Legal Proceedings

In July 2020, Tesoro High Plains Pipeline Company, LLC (“THPP”), a subsidiary of 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 demanded the immediate cessation of pipeline operations and 
assessed trespass damages of approximately $187 million. After subsequent appeal proceedings and in compliance with a new 
order issued by the BIA, in December 2020, THPP paid approximately $4 million in assessed trespass damages and ceased use 
of the portion of the pipeline that crosses the property at issue. In March 2021, the BIA issued an order purporting to vacate the 
BIA's prior orders related to THPP’s alleged trespass and direct the Regional Director of the BIA to reconsider the issue of 
THPP’s alleged trespass and issue a new order. In April 2021, THPP filed a lawsuit in the District of North Dakota against the 
United States of America, the U.S. Department of the Interior and the BIA (together, the “U.S. Government Parties”) challenging 

120

 
 
 
 
 
 
 
 
 
 
the March 2021 order purporting to vacate all previous orders related to THPP’s alleged trespass. On February 8, 2022, the U.S. 
Government Parties filed their answer and counterclaims to THPP’s suit claiming THPP is in continued trespass with respect to 
the pipeline and seek disgorgement of pipeline profits from June 1, 2013 to present, removal of the pipeline and remediation. We 
intend to vigorously defend ourselves against these counterclaims.

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, individually or collectively, 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, 2022.

Dakota Access Pipeline

MPLX holds a 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. In 
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 prepare an environmental impact statement (“EIS”) 
relating to an easement under Lake Oahe in North Dakota. The D.D.C. later vacated the easement. The Army Corps expects to 
release a draft EIS in 2023. 

In May 2021, the D.D.C. denied a renewed request for an injunction to shut down the pipeline while the EIS is being prepared. In 
June 2021, the D.D.C. issued an order dismissing without prejudice the tribes’ claims against the Dakota Access Pipeline. The 
litigation could be reopened or new litigation challenging the EIS, once completed, could be filed. The pipeline remains 
operational.

MPLX has entered into a Contingent Equity Contribution Agreement whereby it, 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. If the 
pipeline were temporarily shut down, 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. MPLX also expects to 
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 1% redemption premium required 
pursuant to the indenture governing the notes) and any accrued and unpaid interest. As of December 31, 2022, our maximum 
potential undiscounted payments under the Contingent Equity Contribution Agreement were approximately $170 million.

Crowley Blue Water Partners

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, 2022, our maximum potential undiscounted payments under this arrangement was $101 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.

121

Other guarantees 

We have entered into other guarantees with maximum potential undiscounted payments totaling $160 million as of December 31, 
2022, 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, a commitment to pay a 
termination fee on a supply agreement if terminated during the initial term, and leases of assets containing general lease 
indemnities and guaranteed residual values.

General guarantees associated with dispositions 

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

Contractual Commitments and Contingencies

At December 31, 2022, our contractual commitments to acquire property, plant and equipment totaled $289 million. Our 
contractual commitments to acquire property, plant and equipment totaled $565 million at December 31, 2021, primarily 
consisting of refining projects which includes the conversion of the Martinez refinery to a renewable diesel facility. 

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.

30.  Subsequent Events

Incremental $5 Billion Share Repurchase Authorization

On January 31, 2023, we announced that our board of directors approved an incremental $5.0 billion share repurchase 
authorization. The authorization has no expiration date. We may utilize various methods to effect the repurchases, which could 
include open market repurchases, negotiated block transactions, accelerated share repurchases, tender offers or open market 
solicitations for shares, some of which may be effected through Rule 10b5-1 plans. The timing of repurchases will depend upon 
several factors, including market and business conditions, and repurchases may be discontinued at any time.

MPLX Senior Notes

On February 9, 2023, MPLX issued $1.6 billion aggregate principal amount of senior notes in a public offering, consisting of 
$1.1 billion aggregate principal amount of 5.00% senior notes due March 2033 and $500 million principal amount of 5.65% senior 
notes due March 2053.

On February 15, 2023, MPLX used $600 million of the net proceeds to redeem all of the outstanding Series B preferred units. 
MPLX also provided notice to redeem all of MPLX’s and MarkWest’s $1.0 billion 4.50% senior notes due July 2023.

CO RPOR ATE INFORMATION

Dividends on common stock, as may be declared by the Board of 
Directors, are typically paid mid-month in March, June, September and 
December. 

Dividend Checks Not Received / Electronic Deposit If you do not receive 
your dividend check on the appropriate payment date, we suggest that 
you wait at least 10 days after the payment date to allow for any delay 
in mail delivery. After that time, advise Computershare by phone or in 
writing to issue a replacement check. You may contact Computershare to 
authorize electronic deposit of your dividends into your bank account.

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.

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,” “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 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, 2022, 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.
