2022
ANNUAL REPORT
FRO M THE PR ES IDENT A N D CE O
Fellow Unitholders,
Over the course of 2022, MPLX demonstrated the
strength of our system as a platform for growth. We
successfully executed on our strategic priorities of
strict capital discipline, fostering a low-cost culture and
optimizing our asset portfolio. These remain foundational
to our execution. Through our focus on providing safe,
reliable and efficient services, we generated robust cash
flow, enabling the return of capital to unitholders and
investment in selective, high-return projects to grow
the business. Through these integrated efforts, we grew
adjusted EBITDA by 4% to $5.8 billion(a) in 2022, and
MPLX returned over $3.5 billion of capital to unitholders
through our distribution and unit repurchases. In
November, based on our confidence in the strength and
growth of our cash flows, we increased our distribution
by 10% to an annual rate of $3.10 per common unit, while
maintaining a distribution coverage ratio of 1.6x.(a)
Strong operational performance and customer demand
drove record annual pipeline throughputs as well
as increases in quarterly gathering, processing and
fractionation throughputs throughout 2022. We realized
adjusted EBITDA growth from recent capital investments
and maintained our commitment to embedding a
low-cost culture through a focus on achieving operational
excellence by reducing costs in our control, improving
efficiency, and driving continuous improvement. We
also made progress toward our goal of leading in
sustainable energy through our methane emissions
intensity reduction program, our right-of-way biodiversity
initiative, and energy efficiency improvements at several
of our terminals, which were subsequently recognized by
U.S. Environmental Protection Agency’s ENERGY STAR®
Challenge for Industry program.
A DISCIPLINED APPROACH TO GROWTH
MPLX’s strong balance sheet supports our strategy
execution, and throughout the year we advanced several
organic growth projects focused on expanding and de-
bottlenecking our existing assets and increasing our capacity
to meet customer demand. Additionally, in the second
quarter, we renewed several pipeline transportation services
agreements with Marathon Petroleum Corporation (MPC)
for pipeline systems which are fit for purpose and integral to
MPC’s refining and marketing operations. The agreements
were extended through 2032 and have two automatic
renewal provisions which would extend the terms to 2042.

MPLX 2022 ANNUAL REPORT
In our Logistics & Storage (L&S) segment, we are
expanding natural gas long-haul and crude oil gathering
pipelines supporting the Permian and Bakken basins.
Specifically in the Permian, working with our partners,
MPLX is progressing its natural gas strategy through
expansion of the Whistler pipeline from 2.0 to 2.5 billion
cubic feet per day and construction of new laterals into
the Midland Basin and Corpus Christi markets.
In our Gathering & Processing (G&P) segment, we
prioritized our investments largely in the Permian and
Marcellus basins in response to producer demand. In
the Permian Basin, our 200 million cubic feet per day
Torñado ll processing plant was placed into operation at
the end of 2022, and we are progressing construction of
our sixth 200 million cubic feet per day processing plant
in the basin, Preakness ll, which is expected to come
online in the first half of 2024. In the Marcellus Basin, our
Smithburg de-ethanizer began operations in the third
quarter of 2022, increasing our de-ethanization capacity
to over 300 thousand barrels per day in the basin. We
are also advancing construction of Harmon Creek ll, a
200 million cubic feet per day processing plant, which is
expected to come online in the first half of 2024.
These disciplined investments are expected to support
the growth of our cash flows. MPLX’s 2023 capital
expenditure plan includes approximately $800 million of
growth capital for projects intended to further optimize
and expand our system to meet demand while targeting
delivery of peer-leading returns on our investments. As
MPLX provides key midstream services in support of
MPC’s production and delivery of renewable fuels, we will
also continue to evaluate low carbon opportunities where
we can leverage technologies that are complementary
with our asset base and expertise.
POSITIONING FOR THE LONG TERM
Our approach to sustainability spans the environmental,
social and governance dimensions of our business, and over
the past year, MPLX took deliberate steps to strengthen the
resiliency of our operations and position the company to
meet the needs of an evolving energy landscape.
In February 2022, we committed to reduce methane
emissions intensity 75% below 2016 levels by 2030 across
our natural gas gathering and processing operations. This
goal expanded on our previous target to reduce methane
On the cover: MPLX’s Houston, Pennsylvania, natural gas

Marcellus Basin.
emissions intensity 50% below 2016 levels by 2025, which
we achieved at the end of 2022. Our progress is driven by our
Focus on Methane program, which takes a holistic approach to
identifying and implementing solutions throughout our system.
Leveraging proven land management techniques, MPLX’s
subsidiary Marathon Pipe Line LLC (MPL) set a biodiversity
target of applying sustainable landscapes to 50% of compatible
MPL rights-of-way by the end of 2025. Last year, we advanced
partnerships, scaled processes and conducted hundreds of site
evaluations towards this goal of protecting pipeline integrity
while promoting long-term environmental health. MPLX is also
actively participating in public-private alliances to explore and
develop pathways for emerging opportunities around carbon
capture, utilization and sequestration.
LOOKING AHEAD
We are optimistic about the opportunities ahead in 2023
and MPLX’s role in meeting the world’s need for reliable,
affordable and responsibly produced energy. Our optimism
is underpinned by the strength of our financial position
and the passion and dedication of our talented workforce.
Grounded in our Core Values, we remain steadfast in our
commitment to safely operate our assets, protect the health
and safety of our employees, and support the communities
where we operate. We firmly believe our disciplined approach
to growth, low-cost culture and operational excellence will
enable us to continue generating strong cash flow,
which enhances our financial flexibility to invest
in and grow the business while also returning
capital to our unitholders.
I am proud to lead MPLX, and I am grateful
for the work our people do each day to
deliver value for our business and our
unitholders. Thank you for supporting
our company.
Sincerely,
Michael J. Hennigan

SUSTAINABILITY
MPLX is focused on meeting the energy needs of today while investing in an energy-diverse future. 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 many stakeholders.
STRENGTHENING R ESILIENCY
We’re strengthening our current business while building durability for the long term. Through our Focus on Methane
program, MPLX takes a holistic approach to reducing methane emissions along all aspects of our gathering and
processing system. As one of the largest natural gas processors in the U.S., MPLX facilitates over 250 million tonnes
of carbon dioxide equivalent reductions per year from coal to gas switching. By lowering the methane intensity of our
operations and improving our energy efficiency, we continue to reduce our carbon footprint and help ensure natural
gas delivers on its promise of significantly lower carbon intensity compared to coal.
Based on our progress, in 2022 we enhanced our methane emissions intensity reduction target by adding a 2030
goal. Additionally, tracked by our biodiversity target, MPLX subsidiary Marathon Pipe Line (MPL) is harnessing the
power of nature-based solutions and applying sustainable landscapes to our compatible rights-of-way to enhance safe
operations and promote long-term environmental health.

IN NOVATI NG FOR TH E FUTUR E
We’re participating in the energy evolution mainly
through our midstream assets and operations which
play a key role in supporting Marathon Petroleum’s
production and delivery of renewable fuels. We
continue to evaluate low carbon opportunities
where we can leverage technologies that are
complementary with our asset footprint and
expertise, while maintaining strict capital discipline.
MPLX is actively involved in alliances to explore and
develop pathways for emerging opportunities around
carbon capture, utilization and sequestration (CCUS).
Near-term efforts of CCUS alliances are to cultivate
business opportunities, increase the understanding
and importance of these technologies and progress
enabling legislation and regulations.

footprint. Indigenous perspectives on safety and the preservation of cultural and environmental resources inform our
planning and execution of projects and operational activities.
In 2022, we continued to evolve our model public engagement program, Earning Your Trust, sharing critical
awareness and education about pipeline safety and infrastructure with stakeholders. Additionally, we strive to make
a positive, measurable impact in our communities through strategic community investments and by encouraging
and incentivizing employee giving and volunteerism. Linking environmental, social and governance (ESG) metrics to
executive and employee compensation emphasizes sustainability in our decision-making.

NO N-GAAP FINANCIAL ME AS UR E S
Adjusted EBITDA and distribution coverage ratio are non-GAAP financial measures. We define Adjusted EBITDA as
net income adjusted for provision for income taxes, interest and other financial costs, depreciation and amortization,
income from equity method investments, distributions and adjustments related to equity method investments, gain
on sales-type leases, impairment expense, noncontrolling interests, and other adjustments as deemed necessary. We
define the distribution coverage ratio as the ratio of distributable cash flow (DCF) attributable to General Partner (GP)
and Limited Partner (LP) unitholders to total GP and LP distributions declared. We define DCF as adjusted EBITDA
adjusted for deferred revenue impacts, sales-type lease payments, net of income, net interest and other financial costs,
net maintenance capital expenditures, equity method investment maintenance capital expenditures paid out, and other
adjustments as deemed necessary.
For a reconciliation of Adjusted EBITDA and DCF to their most directly comparable measures calculated and presented
in accordance with GAAP, see page 52 of MPLX’s Annual Report on Form 10-K for the year ended December 31, 2022.
These non-GAAP financial measures should not be considered alternatives to GAAP net income or net cash provided by
operating activities as they have important limitations as analytical tools because they exclude some but not all items
that affect net income and net cash provided by operating activities or any other measure of financial performance or
liquidity presented in accordance with GAAP.

Part I
Item 1. Business
OVERVIEW
We are a diversified, large-cap master limited partnership formed by MPC in 2012 (as our sponsor) that owns and operates
midstream energy infrastructure and logistics assets, and provides fuels distribution services. Our assets include a network of
crude oil and refined product pipelines; an inland marine business; light-product, asphalt, heavy oil and marine terminals; storage
caverns; refinery tanks, docks, loading racks, and associated piping; crude oil and natural gas gathering systems and pipelines;
as well as natural gas and NGL processing and fractionation facilities. The business consists of two segments based on the
nature of services it offers: Logistics and Storage (“L&S”) and Gathering and Processing (“G&P”). Our assets are positioned
throughout the United States. The L&S segment primarily engages in the gathering, transportation, storage and distribution of
crude oil, refined products, other hydrocarbon-based products, and renewables. The L&S segment also includes the operation of
our refining logistics, fuels distribution and inland marine businesses, terminals, rail facilities and storage caverns. The G&P
segment provides gathering, processing and transportation of natural gas as well as the transportation, fractionation, storage and
marketing of NGLs. For more information on these segments, see Our Operating Segments discussion below. The map below
and Item 2. Properties provide information about our assets as of December 31, 2022:
We continue to have a strategic relationship with MPC, which is a large source of our revenues. We have executed numerous
long-term, fee-based agreements with minimum volume commitments with MPC which provide us with a stable and predictable
revenue stream and source of cash flows. As of December 31, 2022, MPC owned our general partner and approximately 65
percent of our outstanding common units. In 2022, MPC accounted for 47 percent of our total revenues and other income,
primarily within our L&S segment, and will continue to be an important source of our revenues and cash flows for the foreseeable
future. We also have long-term relationships with a diverse set of producer customers in many crude oil and natural gas resource
plays, including the Marcellus Shale, Permian Basin, Utica Shale, STACK Shale and Bakken Shale, among others.
MPLX remains guided by its strategic priorities of strict capital discipline, fostering a low-cost culture, and optimizing our asset
portfolio. We continuously evaluate our portfolio to identify opportunities to develop, expand, debottleneck and participate in
projects that complement our existing assets, assess strategic acquisitions, and ensure we are optimizing all assets in the
portfolio. This includes positioning the MPLX portfolio and capabilities to be successful through the energy evolution.

INDUSTRY OVERVIEW
As of December 31, 2022, our diversified services in the midstream sector broken down by our segments are as follows:
L&S:
The midstream sector plays a crucial role in the oil and gas industry by providing gathering, transportation, terminalling, storage
and marketing services as depicted below.
Crude oil is the primary raw material for transportation fuels and the basis for many products, including plastics, petrochemicals
and heating oil for homes. Pipelines bring advantaged North American crude oil from the upper Great Plains, Louisiana, Texas,
Canada and West Coast to numerous refineries throughout the United States. Terminals provide for the receipt, storage,
blending, additization, handling and redelivery of refined products via pipeline, rail, marine and over-the-road modes of
transportation. This network of logistics infrastructure also allows for export opportunities by connecting supply to global demand
markets. The hydrocarbon market is often volatile and the ability to take advantage of fast-moving market conditions is enhanced
by the ability to store crude oil, refined products, other hydrocarbon-based products, and renewables at tank farms, caverns, and
tanks at refineries and terminals. The ability to store various products provides flexibility and logistics optionality which allows
participants within the industry to take advantage of changing market conditions.
G&P:
The midstream natural gas industry is the link between the exploration for, and production of, natural gas and the delivery of its
hydrocarbon components to end-use markets, as graphically depicted and further described below:
•
Gathering. The natural gas production process begins with the drilling of wells into gas-bearing rock formations. At the
initial stages of the midstream value chain, our network of pipelines known as gathering systems directly connect to
wellheads in the production area. Our gathering systems then transport raw, or untreated, natural gas to a central
location for treating and processing.
6
•
•
•
Processing. Natural gas has a widely varying composition depending on the field, formation reservoir or facility from
which it is produced. Our natural gas processing complexes remove the heavier and more valuable hydrocarbon
components, which are extracted as a mixed NGL stream that includes ethane, propane, butanes and natural gasoline
(also referred to as “y-grade”). Processing aids in allowing the residue gas remaining after extraction of NGLs to meet
the quality specifications for long-haul pipeline transportation and commercial use.
Fractionation. Fractionation is the further separation of the mixture of extracted NGLs into individual components for
end-use sale. Fractionation systems typically exist either as an integral part of a gas processing plant or as a central
fractionator.
Storage, transportation and marketing. Once the raw natural gas has been treated or processed and the raw NGL mix
has been fractionated into individual NGL components, the natural gas is delivered to downstream transmission
pipelines and NGL components are stored, transported and marketed to end-use markets.
Due to advances in well completion technology and horizontal drilling techniques, unconventional sources, such as shale and
tight sand formations, have become a source of current and expected future natural gas production. The industry as a whole is
characterized by regional competition, based on the proximity of gathering systems and processing/fractionation plants to
producing natural gas wells, or to facilities that produce natural gas as a byproduct of refining crude oil. Due to the shift in the
source of natural gas production, midstream providers with a significant presence in the shale plays will likely have a competitive
advantage. Well-positioned operations allow access to all major NGL markets and provide for the development of export
solutions for producers. This proximity is enhanced by infrastructure build-out and pipeline projects.
OUR OPERATING SEGMENTS
We conduct our operations in two reportable segments, which include L&S and G&P. Each of these segments is organized and
managed based upon the nature of the products and services it offers.
L&S:
The L&S segment includes gathering, transportation, storage and distribution of crude oil, refined products, other hydrocarbon-
based products and renewables. These assets consist of a network of 15,105 miles of wholly and jointly-owned common carrier
pipelines and associated storage assets, refining logistics assets at 13 refineries, 89 terminals including one export terminal,
storage caverns, tank farm assets including rail and truck racks, an inland marine business and a fuels distribution business. For
information related to our L&S assets, please see Item 2. Properties - Logistics and Storage. Our L&S assets are integral to the
success of MPC’s operations. We continue to evaluate projects and opportunities that will further enhance our existing
operations and provide valuable services to MPC and third parties.
We generate revenue in the L&S segment primarily by charging tariffs for gathering and transporting crude oil, refined products,
other hydrocarbon-based products and renewables through our pipelines and at our barge docks delivering to domestic and
international destinations, and fees for storing crude oil, refined products and renewables at our storage facilities. Our marine
business generates revenue under a fee-for-capacity contract with MPC. Our fuels distribution business provides services
related to the scheduling and marketing of products on behalf of MPC, for which it generates revenue based on the volume of
MPC’s products sold each month. We are also the operator of additional crude oil and refined product pipelines owned by MPC
and third parties for which we are paid operating fees. For the year ended December 31, 2022, approximately 88 percent of L&S
segment revenues and other income was generated from MPC.
G&P:
The G&P segment gathers, processes and transports natural gas; and transports, fractionates, stores and markets NGLs. As of
December 31, 2022, gathering and processing assets available to MPLX included approximately 10.4 Bcf/d of gathering
capacity, 12.0 Bcf/d of natural gas processing capacity and 829 mbpd of fractionation and de-ethanization capacity. For a
summary of our gas processing facilities, fractionation facilities, natural gas gathering systems, NGL pipelines and natural gas
pipelines see Item 2. Properties - Gathering and Processing. For the year ended December 31, 2022, revenues earned from two
customers within the Marcellus region were significant to the segment. Neither of these customers was significant to MPLX
consolidated revenues.
For further financial information regarding our segments, see Item 7. Management’s Discussion and Analysis of Financial
Condition and Results of Operations and Item 8. Financial Statements and Supplementary Data included in this Annual Report
on Form 10-K.

OUR RELATIONSHIP WITH MPC
One of our competitive strengths is our strategic relationship with MPC, which is the largest crude oil refiner in the United States
in terms of refining capacity. MPC owns and operates 13 refineries in the Gulf Coast, Mid-Continent and West Coast regions of
the United States and distributes refined products, including renewable diesel, through transportation, storage, distribution and
marketing services provided by its midstream segment, which primarily consists of MPLX. MPLX, through its fuels distribution
services, distributes refined products under the Marathon brand through an extensive network of retail locations owned or
operated by independent entrepreneurs across the United States.
MPC retains a significant interest in us through its non-economic ownership of our general partner and holding approximately 65
percent of the outstanding common units of MPLX as of December 31, 2022. Given MPC’s significant interest in us, we believe
MPC will promote and support the successful execution of our business strategies.
OUR L&S CONTRACTS WITH MPC AND THIRD PARTIES
Transportation Services Agreements, Storage Services Agreements, Terminal Services Agreements and Fuels
Distribution Services Agreement with MPC
Our L&S assets are strategically located within, and integral to, MPC’s operations. We have entered into multiple transportation,
terminal and storage services agreements with MPC. Under these long-term, fee-based agreements, we provide transportation,
terminal and storage services to MPC and, other than under our marine transportation services agreement, most of these
agreements include minimum committed volumes from MPC. MPC has also committed to pay a fixed fee for 100 percent of
available capacity for boats, barges and third-party chartered equipment under the marine transportation services agreement.
We also have a fuels distribution agreement with MPC under which we provide scheduling and other services of MPC’s products.
The following table sets forth additional information regarding our transportation, storage, terminal, and fuels distribution services

(1) Commitments are adjusted for crude viscosity. Renewal terms include multiple two to five-year terms.
(2) Renewal terms include multiple one to five-year terms.
(3) MPC has committed to utilize 100 percent of our available capacity of boats and barges. Renewal terms include two additional five-year
terms. The contract is currently within the first renewal period.
(4) Volume shown represents total shell capacity available for MPC’s use and includes refining logistics tanks. Renewal terms vary and range
from year-to-year to multiple additional five-year terms.
(5) Renewal terms vary and range from zero to 10 years. Volume shown represents total shell capacity.
(6) Renewal terms vary and range from month-to-month to two additional five-year terms.
(7)
Includes one additional five-year renewal term.
Under transportation services agreements containing minimum volume commitments, if MPC fails to transport its minimum
throughput volumes during any period, then MPC will pay us a deficiency payment equal to the volume of the deficiency
multiplied by the tariff rate then in effect. Under certain transportation services agreements, the amount of any deficiency
payment paid by MPC may be applied as a credit for any volumes transported on the applicable pipeline in excess of MPC’s
minimum volume commitment during a limited number of succeeding periods, after which time any unused credits will expire.
We have a trucking transportation services agreement with MPC. Under this trucking transportation services agreement, we
receive a service fee per barrel for gathering barrels and providing trucking, dispatch, delivery and data services.
Under most of our terminal services agreements, if MPC fails to meet its minimum volume commitment during any period, then
MPC will pay us a deficiency payment equal to the volume of the deficiency multiplied by the contractual fee then in effect. Some
of our terminal services agreements contain minimum commitments for various additional services such as storage and blending.
8
We have a fuels distribution service agreement with MPC in which MPC pays MPLX a tiered monthly fee based on the volume of
MPC’s products marketed by MPLX each month, subject to a maximum annual volume. MPLX has agreed to use commercially
reasonable efforts to sell not less than a minimum quarterly volume of MPC’s products during each calendar quarter. If MPLX
sells less than the minimum quarterly volume of MPC’s products during any calendar quarter despite its commercially reasonable
efforts, MPC will pay MPLX a deficiency payment equal to the volume deficiency multiplied by the applicable tiered fee. The
dollar amount of actual sales volume of MPC’s products that exceeds the minimum quarterly volume (an “Excess Sale”) for a
particular quarter will be applied as a credit, on a first-in-first-out basis, against any future deficiency payment owed by MPC to
MPLX during the four calendar quarters immediately following the calendar quarter in which the Excess Sale occurs.
Our agreements with MPC provide for annual escalations that are either fixed or based on a variety of factors including the
FERC index and various other inflation-based indexes depending on the nature and geography of the services provided.
Pipeline Operating Agreements with MPC
We operate various pipelines owned by MPC under operating services agreements. Under these operating services agreements,
we receive an operating fee for operating the assets, which include certain MPC wholly owned or partially owned crude oil,
natural gas, and refined product pipelines, and for providing various operational services with respect to those assets. We are
generally reimbursed for all direct and indirect costs associated with operating the assets and providing such operational
services. These agreements vary in length and automatically renew with most agreements being indexed for inflation.
Pipeline Operating Agreements with Third Parties
We maintain and operate six pipelines in which either MPC or MPLX has a joint interest. We receive an operating fee for each of
these pipelines, which is subject to adjustment for inflation. In addition, we are reimbursed for specific costs associated with
operating each pipeline. The length and renewal terms for each agreement vary.
Transportation, Terminal and Storage Services Agreements with Third Parties
We have multiple transportation and terminal services agreements with third parties under which we provide use of pipelines and
tank storage, and provide services, facilities and other infrastructure related to the receipt, storage, throughput, blending and
delivery of commodities. Some of these agreements are subject to prepaid throughput volumes under which we agree to handle
a certain amount of product throughput each month in exchange for a predetermined fixed fee, with any excess throughput or
ancillary services subject to additional charges. Under the remaining agreements, we receive an agreed upon fee based on
actual product throughput following the completion of services.
Marine Services Agreements with MPC
MPLX has an agreement with MPC under which it provides management services to assist MPC in the oversight and
management of the marine business. MPLX receives fixed annual fees for providing the required services, which are subject to
predetermined annual escalation rates. This agreement is subject to an initial term of five years and automatically renews for one
additional five-year renewal period unless terminated by either party.
Other Agreements with MPC
We have omnibus agreements with MPC that address our payment of a fixed annual fee to MPC for the provision of executive
management services by certain executive officers of our general partner and our reimbursement to MPC for the provision of
certain services to us, as well as MPC’s indemnification of us for certain matters, including certain environmental, title and tax
matters. In addition, we indemnify MPC for certain matters under these agreements.
We also have various employee services agreements and a secondment agreement under which we reimburse MPC for the
provision of certain operational and management services to us. All of the employees that conduct our business are directly
employed by affiliates of our general partner.
Additionally, we have certain indemnification agreements with MPC under which MPC retains responsibility for remediation of
known environmental liabilities due to the use or operation of the assets prior to our ownership, and indemnifies us for any losses
we incurred arising out of those remediation obligations. The indemnification for unknown pre-closing remediation liabilities is
generally limited to five years.
OUR G&P CONTRACTS WITH MPC AND THIRD PARTIES
The majority of our revenues in the G&P segment are generated from natural gas gathering, transportation and processing; and
NGL transportation, fractionation, exchange, marketing and storage. MPLX enters into a variety of contract types including fee-
based, percent-of-proceeds, keep-whole and purchase arrangements in order to generate revenues. See Item 8. Financial
Statements and Supplementary Data - Note 2 for a further description of these different types of arrangements.
9
In many cases, MPLX provides services under contracts that contain a combination of more than one of the arrangements
described above. The terms of MPLX’s contracts vary based on gas quality conditions, the competitive environment when the
contracts are signed and customer requirements. In addition, minimum volume commitments may create contract liabilities or
deferred credits if current period payments can be used for future services. These are recognized into service revenue in
instances where it is probable the customer will not use the credit in future periods.
MPLX’s contract mix and exposure to natural gas and NGL prices may change as a result of changes in producer preferences,
MPLX expansion in regions where some types of contracts are more common and other market factors, including current market
and financial conditions which have increased the risk of volatility in oil, natural gas and NGL prices. Any change in mix may
influence our long-term financial results.
Keep-whole agreement with MPC
MPLX has a keep-whole commodity agreement related to our Rockies operations with MPC. Under the agreement, MPC pays us
a processing fee for NGLs related to keep-whole agreements and delivers shrink gas to the producers on our behalf. We pay
MPC a marketing fee in exchange for assuming the commodity risk. The pricing structure under this agreement provides for a
base volume subject to a base rate and incremental volumes subject to variable rates, which are calculated with reference to
certain of our costs incurred as processor of the volumes. The pricing for both the base and incremental volumes are subject to
revision each year.
COMPETITION
Within our L&S segment, our competition primarily comes from independent terminal and pipeline companies, integrated
petroleum companies, refining and marketing companies, distribution companies with marketing and trading arms and from other
wholesale petroleum products distributors. Competition in any particular geographic area is affected significantly by the volume
of products produced by refineries in the area, and in areas where no refinery is present, by the availability of products and the
cost of transportation to the area from other locations. Competition for oil supplies is based primarily on the price and scope of
services, location of the facility and connectivity to the best priced markets.
As a result of our contractual relationship with MPC under our transportation and storage services agreements, our terminal
services agreement, our fuels distribution agreement and our physical asset connections to MPC’s refineries and terminals, we
believe that MPC will continue to utilize our assets for transportation, storage, distribution and marketing services. If MPC’s
customers reduced their purchases of refined products from MPC due to increased availability of less expensive refined product
from other suppliers or for other reasons, MPC may only receive or deliver the minimum volumes through our terminals (or pay
the shortfall payment if it does not deliver the minimum volumes), which could decrease our revenues.
In our G&P segment, we face competition for natural gas gathering and in obtaining natural gas supplies for our processing and
related services; in obtaining unprocessed NGLs for 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 services supplied to the customer. 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.
Our G&P competitors include:
•
natural gas midstream providers, of varying financial resources and experience, that gather, transport, process,
fractionate, store and market natural gas and NGLs;
• major integrated oil companies and refineries;
•
•
•
independent exploration and production companies;
interstate and intrastate pipelines; and
other marine and land-based transporters of natural gas and NGLs.
Certain competitors, such as major oil and gas and pipeline companies, may have capital resources and contracted supplies of
natural gas substantially greater than ours. Smaller local distributors may have a marketing advantage in their immediate service
areas.
We believe that our customer focus, demonstrated by our ability to offer an integrated package of services and our flexibility in
considering various types of contractual arrangements, allows us to compete more effectively. This includes having access to
both NGL and natural gas markets to allow for flexibility in our gathering and processing in addition to having critical connections
to a strong sponsor and key market outlets for NGLs and natural gas. Our strategic gathering and processing agreements with
key producers enhances our competitive position to participate in the further development of our resource plays. The strategic
10
location of our assets, including those connected to MPC, and the long-term nature of many of our contracts also provide a
significant competitive advantage.
INSURANCE
Our assets may experience physical damage as a result of an accident or natural disaster. These hazards can also cause
personal injury and loss of life, severe damage to and destruction of property and equipment, pollution or environmental damage
and business interruption. We are insured under MPC and other third-party insurance policies. The MPC policies are subject to
shared deductibles.
SEASONALITY
The volume of crude oil and refined products transported and stored utilizing our assets is affected by the level of supply and
demand for crude oil and refined products in the markets served directly or indirectly by our assets. The majority of effects of
seasonality on the L&S segment’s revenues will be mitigated through the use of our fee-based transportation and storage
services agreements with MPC that include minimum volume commitments.
In our G&P segment, we experience minimal impacts from seasonal fluctuations which impact the demand for natural gas and
NGLs and the related commodity prices caused by various factors including variations in weather patterns from year to year. We
are able to manage the seasonality impacts through the execution of our marketing strategy. Overall, our exposure to the
seasonality fluctuations is limited due to the nature of our fee-based business.
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 Interstate Commerce Act (“ICA”), the Natural Gas Act (“NGA”), the Clean Water
Act (“CWA”) with respect to water discharges, the Clean Air Act (“CAA”) with respect to air emissions, 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.
Pipeline Regulations
Liquids Pipelines
Some of our existing pipelines are considered interstate common carrier pipelines subject to regulation by the Federal Energy
Regulatory Commission (“FERC”) under 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, and certain of our pipelines have subsequently been approved to charge market-based rates.
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.
11
Intrastate services provided by certain of our liquids pipelines are subject to regulation by state regulatory authorities. Much of
the state regulation is complaint-based, both as to rates and priority of access. Not all state regulatory bodies allow for changes
based on an index method similar to that used by FERC. In those instances, rates are generally changed only through a rate
case process. The state regulators could limit our ability to increase our rates or to set rates based on our costs or could order us
to reduce our rates and could, if permitted under state law, require the payment of refunds to shippers.
FERC and state regulatory agencies generally have not investigated rates on their own initiative when those rates are not the
subject of a protest or a complaint by a shipper. FERC or a state commission could investigate our rates on its own initiative or at
the urging of a third party if the third party is either a current shipper or is able to show that it has a substantial economic interest
in our tariff rate level.
Natural Gas Pipelines
Our natural gas pipeline operations are subject to federal, state and local regulatory authorities. Under the NGA, FERC has
authority to regulate natural gas companies that provide natural gas pipeline transportation services in interstate commerce.
FERC’s authority to regulate those services includes the rates charged for the services, terms and conditions of service,
certification and construction of new facilities, the extension or abandonment of services and facilities, the maintenance of
accounts and records, the acquisition and disposition of facilities, the initiation and discontinuation of services and various other
matters. Natural gas companies may not charge rates that have been determined to be unjust and unreasonable, or unduly
discriminatory by FERC. In addition, FERC prohibits FERC-regulated natural gas companies from unduly preferring, or unduly
discriminating against, any person with respect to pipeline rates or terms and conditions of service or other matters. Pursuant to
FERC’s jurisdiction, existing rates and/or other tariff provisions may be challenged (e.g., by complaint) and rate increases
proposed by the pipeline or other tariff changes may be challenged (e.g., by protest). Any successful complaint or protest related
to our services or facilities could have an adverse impact on our revenues.
Some of our intrastate gas pipeline facilities are subject to various state laws and regulations that affect the rates we charge and
terms of service. Although state regulation is typically less onerous than FERC, state regulation typically requires pipelines to
charge just and reasonable rates and to provide service on a non-discriminatory basis. The rates and service of an intrastate
pipeline generally are subject to challenge by complaint. Additionally, FERC has adopted certain regulations and reporting
requirements applicable to intrastate natural gas pipelines (and Hinshaw natural gas pipelines) that provide certain interstate
services subject to FERC’s jurisdiction. We are subject to such regulations and reporting requirements to the extent that any of
our intrastate pipelines provide, or are found to provide, such interstate services.
Natural Gas Gathering
Section 1(b) of the NGA exempts natural gas production and gathering from the jurisdiction of FERC. There is, however, no
bright-line test for determining the jurisdictional status of pipeline facilities. We own a number of facilities that we believe qualify
as production and gathering facilities not subject to FERC jurisdiction. The distinction between FERC-regulated transmission
services and federally unregulated gathering services is the subject of litigation from time to time, so we cannot provide
assurance that FERC will not at some point assert that these facilities are within its jurisdiction or that such an assertion would
not adversely affect our results of operations and revenues. In such a case, we would possibly be required to file a tariff with
FERC, potentially provide a cost justification for the transportation charge and obtain certificate(s) of public convenience and
necessity for the FERC-regulated pipelines, and comply with additional FERC reporting requirements.
In the states in which we operate, regulation of gathering facilities and intrastate pipeline facilities generally includes various
safety, environmental and, in some circumstances, open access, non-discriminatory take requirement and complaint-based rate
regulation. For example, some of our natural gas gathering facilities are subject to state ratable take and common purchaser
statutes and regulations. Ratable take statutes and regulations generally require gatherers to take, without undue discrimination,
natural gas production that may be tendered to the gatherer for handling. Similarly, common purchaser statutes and regulations
generally require gatherers to purchase gas without undue discrimination as to source of supply or producer. These statutes are
designed to prohibit discrimination in favor of one producer over another producer or one source of supply over another source of
supply. Although state regulation is typically less onerous than at FERC, these statutes and regulations have the effect of
restricting our right as an owner of gathering facilities to decide with whom we contract to purchase or gather natural gas.
Our gathering operations could be adversely affected should they be subject in the future to the application of state or federal
regulation of rates and services or regulated as a public utility. Our gathering operations also may be or become subject to safety
and operational regulations and permitting requirements relating to the design, siting, installation, testing, construction, operation,
replacement and management of gathering facilities. Additional rules and legislation pertaining to these matters are considered
or adopted from time to time. We cannot predict what effect, if any, such changes might have on our operations, but the industry
could be required to incur additional capital expenditures and increased costs depending on future legislative and regulatory
changes.
12
Energy Policy Act of 2005
Under the Domenici-Barton Energy Policy Act of 2005 (“EPAct 2005”) and related regulations, it is unlawful for gas pipelines and
storage companies that provide interstate services to: (i) directly or indirectly, use or employ any device, scheme or artifice to
defraud in connection with the purchase or sale of natural gas subject to the jurisdiction of FERC, or the purchase or sale of
transportation services subject to the jurisdiction of FERC; (ii) make any untrue statement of material fact or omit to make any
such statement necessary to make the statements made not misleading; or (iii) engage in any act or practice that operates as a
fraud or deceit upon any person. EPAct 2005 gives the FERC civil penalty authority to impose penalties for certain violations of
up to approximately $1.3 million per day for each violation, subject to FERC’s annual inflation adjustment. FERC also has the
authority to order disgorgement of profits from transactions deemed to violate the NGA and the EPAct 2005.
Standards of Conduct
FERC has adopted affiliate standards of conduct applicable to interstate natural gas pipelines and certain other regulated
entities, defined as “Transmission Providers.” Under these rules, a Transmission Provider becomes subject to the standards of
conduct if it provides service to affiliates that engage in marketing functions (as defined in the standards). If a Transmission
Provider is subject to the standards of conduct, the Transmission Provider’s transmission function employees (including the
transmission function employees of any of its affiliates) must function independently from the Transmission Provider’s marketing
function employees (including the marketing function employees of any of its affiliates). The Transmission Provider must also
comply with certain posting and other requirements.
PHMSA Regulation
We are subject to regulation by the DOT under the Hazardous Liquid Pipeline Safety Act of 1979 (“HLPSA”). The HLPSA
delegated to the DOT the authority to develop, prescribe and enforce minimum federal safety standards for the transportation of
hazardous liquids by pipeline. Congress also enacted the Pipeline Safety Act of 1992, also known as the PSA, which added the
environment to the list of statutory factors that must be considered in establishing safety standards for hazardous liquid pipelines,
required regulations be issued to define the term “gathering line” and establish safety standards for certain “regulated gathering
lines,” and mandated that regulations be issued to establish criteria for operators to use in identifying and inspecting pipelines
located in High Consequence Areas (“HCAs”), defined as those areas that are unusually sensitive to environmental damage, that
cross a navigable waterway, or that have a high population density. In 1996, Congress enacted the Accountable Pipeline Safety
and Partnership Act, which limited the operator identification requirement mandate to pipelines that cross a waterway where a
substantial likelihood of commercial navigation exists, required that certain areas where a pipeline rupture would likely cause
permanent or long-term environmental damage be considered in determining whether an area is unusually sensitive to
environmental damage, and mandated that regulations be issued for the qualification and testing of certain pipeline personnel. In
the Pipeline Inspection, Protection, Enforcement, and Safety Act of 2006, Congress required mandatory inspections for certain
U.S. crude oil and natural gas transmission pipelines in HCAs and mandated that regulations be issued for low-stress hazardous
liquid pipelines and pipeline control room management. We are also subject to the Pipeline Safety, Regulatory Certainty and Job
Creation Act of 2011, which increased penalties for safety violations, established additional safety requirements for newly
constructed pipelines and required studies of certain safety issues that could result in the adoption of new regulatory
requirements for existing pipelines. Additionally, we are subject to the Protecting our Infrastructure of Pipelines and Enhancing
Safety Act of 2016, which required PHMSA to develop underground gas storage standards within two years and provided
PHMSA with significant new authority to issue industry-wide emergency orders if an unsafe condition or practices results in an
imminent hazard.
The DOT has delegated its authority under these statutes to the PHMSA, which administers compliance with these statutes and
has promulgated comprehensive safety standards and regulations for the transportation of natural gas by pipeline (49 C.F.R. Part
192), as well as hazardous liquids by pipeline (49 C.F.R. Part 195), including regulations for the design and construction of new
pipelines or those that have been relocated, replaced or otherwise changed (Subparts C and D of 49 C.F.R., Part 195); pressure
testing of new pipelines (Subpart E of 49 C.F.R. Part 195); operation and maintenance of pipelines, including inspecting and
reburying pipelines in the Gulf of Mexico and its inlets, establishing programs for public awareness and damage prevention,
managing the integrity of pipelines in HCAs and managing the operation of pipeline control rooms (Subpart F of 49 C.F.R. Part
195); protecting steel pipelines from the adverse effects of internal and external corrosion (Subpart H of 49 C.F.R. Part 195); and
integrity management requirements for pipelines in HCAs (49 C.F.R. 195.452). PHMSA has undertaken a number of initiatives to
reevaluate its pipeline safety regulations. We do not anticipate that we would be impacted by these regulatory initiatives to any
greater degree than other similarly situated competitors.
Notwithstanding the foregoing, PHMSA and one or more state regulators have, in isolated circumstances in the past, sought to
expand the scope of their regulatory inspections to include certain in-plant equipment and pipelines found within NGL
fractionation facilities and associated storage facilities in order to assess compliance with hazardous liquids pipeline safety
requirements. If any of these actions were made broadly enforceable as part of a rule-making process or codified into law, they
could result in additional capital costs, possible operational delays and increased costs of operation.
13
Environmental and Other Regulations
General
Our processing and fractionation plants, storage facilities, pipelines and associated facilities are subject to multiple obligations
and potential liabilities under a variety of federal, regional, state and local laws and regulations relating to environmental
protection. Such environmental laws and regulations may affect many aspects of our present and future operations, including for
example, requiring the acquisition of permits or other approvals to conduct regulated activities that may impose burdensome
conditions or potentially cause delays, restricting the manner in which we handle or dispose of our wastes, limiting or prohibiting
construction or other activities in environmentally sensitive areas such as wetlands or areas inhabited by threatened or
endangered species, requiring us to incur capital costs to construct, maintain and/or upgrade processes, equipment and/or
facilities, restricting the locations in which we may construct our compressor stations and other facilities and/or requiring the
relocation of existing stations and facilities, and requiring remedial actions to mitigate any pollution that might be caused by our
operations or attributable to former operations. Spills, releases or other incidents may occur in connection with our active
operations or as a result of events outside of our reasonable control, which incidents may result in non-compliance with such
laws and regulations. Any failure to comply with these legal requirements may expose us to the assessment of sanctions,
including administrative, civil and criminal penalties, the imposition of remedial or corrective actions and the issuance of orders
enjoining or limiting some or all of our operations.
We believe that our operations and facilities are in substantial compliance with applicable environmental laws and regulations
and the cost of continued compliance with such laws and regulations will not have a material adverse effect on our results of
operations or financial condition. Generally speaking, however, the trend in environmental law is to place more restrictions and
limitations on activities that may be perceived to adversely affect the environment, which may cause significant delays in
obtaining permitting approvals for our facilities, result in the denial of our permitting applications, or cause us to become involved
in time consuming and costly litigation. Thus, there can be no assurance as to the amount or timing of future expenditures for
compliance with environmental laws and regulations, permits and permitting requirements or remedial actions pursuant to such
laws and regulations, and actual future expenditures may be different from the amounts we currently anticipate. Revised or
additional environmental requirements may result in increased compliance and mitigation costs or additional operating
restrictions, particularly if those costs are not fully recoverable from our customers, and could have a material adverse effect on
our business, financial condition, results of operations and cash flow. We may not be able to recover some or any of these costs
from insurance. Such revised or additional environmental requirements may also result in substantially increased costs and
material delays in the construction of new facilities or expansion of our existing facilities, which may materially impact our ability
to meet our construction obligations with our producer customers.
Remediation
A comprehensive framework of environmental laws and regulations governs our operations as they relate to the possible release
of hazardous substances or non-hazardous or hazardous wastes into soils, groundwater and surface water and measures taken
to mitigate pollution into the environment. CERCLA, also known as the “Superfund” law, as well as comparable state laws,
impose liability without regard to fault or the legality of the original conduct on certain classes of persons who are considered to
be responsible for the release of a hazardous substance into the environment. These persons include current and prior owners
or operators of a site where a release occurred and companies that transported or disposed or arranged for the transport or
disposal of the hazardous substances released from the site. Under CERCLA, these persons may be subject to strict joint and
several liability for the costs of removing or remediating hazardous substances that have been released into the environment and
for restoration costs and damages to natural resources. RCRA and similar state laws may also impose liability for removing or
remediating releases of hazardous or non-hazardous wastes from impacted properties.
We currently own or lease, and have in the past owned or leased, properties that have been used over the years for natural gas
gathering, processing and transportation, for NGL fractionation, for the storage, gathering and transportation of crude oil, or for
the storage and transportation of refined products. During the normal course of operation, whether by us or prior owners or
operators, releases of petroleum hydrocarbons or other non-hazardous or hazardous wastes have or may have occurred. We
could be required to remove or remediate previously disposed wastes or property contamination, including groundwater
contamination, or to perform remedial operations to prevent future contamination. We do not believe that we have any current
material liability for cleanup costs under such laws or for third-party claims.
On September 6, 2022, EPA issued a notice of proposed rulemaking that would designate Perfluorooctanoic Acid (“PFOA”) and
Perfluorooctane Sulfonate (“PFOS”) as hazardous substances under CERCLA Section 102(a). Additional per- and polyfluoroalkyl
substances (“PFAS”) regulation could include the designation of PFAS as a RCRA hazardous waste. We cannot currently predict
the impact of potential statutes or regulations related to PFAS on our remediation costs.
Hazardous and Solid Wastes
We may incur liability under RCRA, and comparable or more stringent state statutes, which impose requirements relating to the
handling and disposal of non-hazardous and hazardous wastes. In the course of our operations, we generate some amount of
ordinary industrial wastes, such as paint wastes, waste solvents and waste oils that may be regulated as hazardous wastes. It is
14
possible that some wastes generated by us that are currently classified as non-hazardous wastes may in the future be
designated as hazardous wastes, resulting in the wastes being subject to more rigorous and costly transportation, storage,
treatment and disposal requirements.
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.
Construction or maintenance of our plants, compressor stations, pipelines, barge docks and storage facilities may impact
wetlands or other surface water bodies, which are also regulated under the CWA by the EPA, the United States Army Corps of
Engineers and state water quality agencies. Regulatory requirements governing wetlands and other surface water bodies
(including associated mitigation projects) may result in the delay of our projects while we obtain necessary permits and may
increase the cost of new projects and maintenance activities. We believe that we are in substantial compliance with the CWA and
analogous state laws. However, there is no assurance that we will not incur material increases in our operating costs or delays in
the construction or expansion of our facilities because of future developments, the implementation of new laws and regulations,
the reinterpretation of existing laws and regulations, or otherwise, including, for example, increased construction activities,
potential inadvertent releases arising from pursuing borings for pipelines, and earth slips due to heavy rain and/or other causes.
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 U.S. 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. Repeal, vacation, 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 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, the EPA issued
lifetime health advisory levels (“HALs”) and health effects support documents for two PFAS substances - PFOA and 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 the EPA is planning to take to study and regulate various PFAS chemicals.
The EPA identified that it would evaluate, among other actions, (1) proposing national drinking water standards for PFOA and
PFOS, (2) develop cleanup recommendations for PFOA and PFOS, (3) evaluate listing PFOA and PFOS as hazardous
substances under CERCLA, and (4) conduct toxicity assessments for other PFAS chemicals. 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
15
further action to regulate PFAS. We cannot currently predict the impact of potential statutes or regulations on our operations. 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 the EPA HALs for PFOS and PFOA and some states are adopting and proposing
state-specific drinking water and cleanup standards for various PFAS, including PFOS and PFOA. We cannot currently predict
the impact of these regulations on our liquidity, financial position, or results of operations.
Air Emissions
The Clean Air Act (“CAA”) and comparable state laws restrict the emission of air pollutants from many sources, including
processing plants and compressor stations, and also impose various monitoring and reporting requirements. These laws and any
implementing regulations may require us to obtain pre-approval for the construction or modification of certain projects or facilities
expected to produce or significantly increase air emissions, obtain and strictly comply with stringent air permit requirements,
utilize specific equipment or technologies to control emissions, or aggregate two or more of our facilities into one application for
permitting purposes. We believe that our operations are in substantial compliance with applicable air permitting and control
technology requirements. However, we may be required to incur capital expenditures in the future for installation of air pollution
control equipment and encounter construction or operational delays while applying for, or awaiting the review, processing and
issuance of new or amended permits, and we may be required to modify certain of our operations which could increase our
operating costs.
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 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.
In 2007, the California Air Resources Board (“CARB”) adopted the At-Berth Regulation to control airborne emissions from ocean-
going vessels at berth but excluded tanker vessels due to safety and technological challenges for stack emission capture on
vessels with hazardous cargo, which challenges still exist today. CARB amended the regulation in August 2020 to include
maximum emission rates from auxiliary engines and boilers used to unload tanker vessels at berth. The obligation to meet the
emission rates applies to both a vessel and the terminal where it is unloading. The emission rates apply to vessels unloading at
terminals at the Port of Long Beach and the Port of Los Angeles beginning January 1, 2025, and at all other terminals beginning
January 1, 2027. The amended regulation has been challenged in court and could impact the compliance timeline. Compliance
with the regulation is expected to increase our costs at affected facilities.
Climate Change
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.
Congress has from time to time considered legislation to reduce emissions of GHGs, and it is possible that such legislation could
be enacted in the future. In the absence of federal climate legislation in the United States, a number of state and regional efforts
have emerged that are aimed at tracking and/or reducing GHG emissions by means of cap and trade programs that typically
require major sources of GHG emissions, such as electric power plants, to acquire and surrender emission allowances in return
for emitting those GHGs. Although it is not possible at this time to predict how legislation or new regulations that may be adopted
to address GHG emissions would impact our business, any such future laws and regulations could require us to incur increased
operating costs, such as costs to purchase and operate emissions control systems, to acquire emission allowances or comply
with new regulatory or reporting requirements including the imposition of a carbon tax. In November 2021, the EPA proposed
regulations that would expand and strengthen methane emission reductions from new, modified and reconstructed oil and natural
gas sources. Any such legislation or regulatory programs could also increase the cost of consuming, and thereby reduce demand
for, oil and natural gas produced by our exploration and production customers that, in turn, could reduce the demand for our
services and thus adversely affect our cash available for distribution to our unitholders.
Under the National Environmental Policy Act, environmental assessments must be performed for certain projects, including
construction of certain new pipelines. The Council on Environmental Quality has sought comment on the extent to which an
environmental assessment must consider direct and indirect GHG emissions from a new project and is undergoing a two phase
process for updating its regulations for implementing the National Environmental Policy Act. Uncertainty related to the
environmental assessment can result in delay and increased costs in completing new projects.
16
On December 6, 2022, EPA issued a proposed rule to regulate methane emissions from the Oil and Natural Gas Sector. The
proposed rule titled “Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for
Existing Sources: Oil and Gas Sector Climate Review” would require MPLX to control and reduce methane emissions within its
natural gas gathering and boosting operations and gas processing facilities. The proposed rule is consistent with the voluntary
methane reduction programs that MPLX has been implementing through its Focus on Methane Program. As a result, we do not
believe the proposed rule as written, if adopted, will have a material impact to our operations.
Endangered Species Act and Migratory Bird Treaty Act Considerations
The federal Endangered Species Act (“ESA”) and analogous state laws regulate activities that may affect endangered or
threatened species, including their habitats. If protected species are located in areas where we propose to construct new
gathering or transportation pipelines, processing or fractionation facilities, or other infrastructure, such work could be prohibited
or delayed in certain of those locations or during certain times, when our operations could result in a taking of the species or
destroy or adversely modify critical habitat that has been designated for the species. We also may be obligated to develop plans
to avoid potential takings of protected species and provide mitigation to offset the effects of any unavoidable impacts, the
implementation of which could materially increase our operating and capital costs. Existing laws, regulations, policies and
guidance relating to protected species may also be revised or reinterpreted in a manner that further increases our construction
and mitigation costs or restricts our construction activities. Additionally, construction and operational activities could result in
inadvertent impact to a listed species and could result in alleged takings under the ESA, exposing MPLX to civil or criminal
enforcement actions and fines or penalties. The existence of threatened or endangered species in areas where we conduct
operations or plan to construct pipelines or facilities may cause us to incur increased costs arising from species protection
measures or could result in delays in, or prohibit, the construction of our facilities or limit our customer’s exploration and
production activities, which could have an adverse impact on demand for our midstream operations.
The Migratory Bird Treaty Act implements various treaties and conventions between the United States and certain other nations
for the protection of migratory birds. In accordance with this law, the taking, killing or possessing of migratory birds covered under
this act is unlawful without authorization. If there is the potential to adversely affect migratory birds as a result of our operations
or construction activities, we may be required to seek authorization to conduct those operations or construction activities, which
may result in specified operating or construction restrictions on a temporary, seasonal, or permanent basis in affected areas and
thus have an adverse impact on our ability to provide timely gathering, processing or fractionation services to our exploration and
production customers.
Safety Matters
We are subject to oversight pursuant to the federal Occupational Safety and Health Act (“OSH Act”), as amended, 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
and the EPA’s Risk Management Program requirements, which are intended to prevent or minimize the consequences of
catastrophic releases of toxic, reactive, flammable or explosive chemicals. The application of these regulations can result in
increased compliance expenditures.
In general, we expect industry and regulatory safety standards to become 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.
Product Quality Standards
Refined products and other hydrocarbon-based products that we transport are generally sold by us or our customers for
consumption by the public. Various federal, state and local agencies have the authority to prescribe product quality specifications
for products. Changes in product quality specifications or blending requirements could reduce our throughput volumes, require
us to incur additional handling costs or require capital expenditures. For example, different product specifications for different
markets affect the fungibility of the products in our system and could require the construction of additional storage. In addition,
changes in the product quality of the products we receive on our product pipelines could reduce or eliminate our ability to blend
products.
17
Marine Transportation
Our marine transportation business is subject to regulation by the USCG, federal laws, including the Jones Act, state laws and
certain international conventions, as well as numerous environmental regulations. The majority of our vessels are subject to
inspection by the USCG and carry certificates of inspection. The crews employed aboard the vessels are licensed or certified by
the USCG. We are required by various governmental agencies to obtain licenses, certificates and permits for our vessels.
Our marine transportation business competes principally in markets subject to the Jones Act, a federal cabotage law that restricts
domestic marine transportation in the United States to vessels built and registered in the United States, and manned and owned
by United States citizens. We presently meet all of the requirements of the Jones Act for our vessels. The loss of Jones Act
status could have a significant negative effect on our marine transportation business. The requirements that our vessels be
United States built and manned by United States citizens, the crewing requirements and material requirements of the USCG, and
the application of United States labor and tax laws increases the cost of United States flag vessels when compared with
comparable foreign flag vessels. Our marine transportation business could be adversely affected if the Jones Act were to be
modified so as to permit foreign competition that is not subject to the same United States government-imposed burdens.
The Secretary of Homeland Security is vested with the authority and discretion to waive the Jones Act to such extent and upon
such terms as the Secretary may prescribe whenever the Secretary deems that such action is necessary in the interest of
national defense. For example, the Secretary has waived the Jones Act for limited periods of time and in limited areas following
the occurrence of certain natural disasters such as hurricanes. Waivers of the Jones Act can result in increased competition from
foreign tank vessel operators, which could negatively impact our marine transportation business.
Security
Certain of our facilities are subject to the Department of Homeland Security Chemical Facility Anti-Terrorism Standards. In
addition, we have several facilities that are subject to the United States Coast Guard’s Maritime Transportation Security Act, and
a number of other facilities that are subject to the Transportation Security Administration’s Pipeline Security Guidelines and are
designated as “Critical Facilities.” We have an internal inspection program designed to monitor and ensure compliance with all of
these requirements. We believe that we are in material compliance with all applicable laws and regulations regarding the security
of our facilities.
Tribal Lands
Various federal agencies, including the EPA and the Department of the Interior, along with certain Native American tribes,
promulgate and enforce regulations pertaining to oil and gas operations on Native American tribal lands where we operate.
These regulations include such matters as lease provisions, drilling and production requirements, and standards to protect
environmental quality and cultural resources. In addition, each Native American tribe is a sovereign nation having the right to
enforce certain laws and regulations and to grant approvals independent from federal, state and local statutes and regulations.
These laws and regulations may increase our costs of doing business on Native American tribal lands and impact the viability of,
or prevent or delay our ability to conduct, our operations on such lands.
HUMAN CAPITAL
We are managed and operated by the board of directors and executive officers of MPLX GP LLC (“MPLX GP”), our general
partner and a wholly owned subsidiary of MPC. Our general partner has the sole responsibility for providing the employees and
other personnel necessary to conduct our operations. All of the employees that conduct our business are directly employed by
affiliates of our general partner. We believe that our general partner and its affiliates have a satisfactory relationship with those
employees.
MPC believes its employees are its greatest asset of strength, and the culture reflects the quality of individuals across its
workforce. Its 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 its
employees and their families, contribute to increased engagement and fulfilling careers. Empowering people and prioritizing
accountability are also key components for developing a high-performing culture, which is critical to achieving our strategic
vision.
Employee Profile
As of December 31, 2022, our general partner and its affiliates, have approximately 5,811 full-time employees that provide
services to us under our employee services agreements.
Safety
MPC is committed to safe operations to protect the health and safety of its employees, contractors and communities. MPC’s
commitment to safe operations is reflected in its safety systems design, its well-maintained equipment and by learning from its
18
incidents. Part of MPC’s effort to promote safety includes the 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 MPC’s safety management system
provide it with a comprehensive approach to managing risks and preventing incidents, illnesses and fatalities. Additionally, MPC’s
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. MPC continues to monitor the situation and adapt their COVID protocols as appropriate.
Talent Management
Executing MPC’s strategic vision requires that it attracts and retains the best talent. Recruiting and retention success requires
that it effectively nurtures new employees, providing opportunities for long-term engagement and career advancement. MPC also
appropriately rewards high-performers and offers competitive benefits. MPC’s Talent Acquisition team consists of three
segments: Executive Recruiting, Experienced Recruiting and University Recruiting. The specialization within each group allows
MPC to specifically address its broad range of current and future talent needs, as well as devote time and attention to candidates
during the hiring process. MPC values diverse perspectives in the workforce, and accordingly seeks candidates with a variety of
backgrounds and experience. MPC’s primary source of full-time, entry-level new hires is its intern/co-op program. Through its
university recruiters, MPC offers college students who have completed their freshman year the opportunity to participate in its
hands-on programs focused in areas of finance and accounting, marketing, engineering and IT.
MPC provides a broad range of leadership training opportunities to support the development of leaders at all levels. Those
programs, which are offered across the organization, are a blended approach of business and leadership content, with many
featuring external faculty. MPC utilizes various learning modalities, such as visual, audio, print, tactile, interactive, kinesthetic,
experiential and leader-teaching-leader to address and engage different learning styles. MPC believes networking and access to
executives are key leadership success factors, and MPC incorporates these opportunities into all of its programs.
Compensation and Benefits
To ensure MPC is offering competitive pay packages in its recruitment and retention efforts, it annually benchmarks
compensation, including base salaries, bonus levels and long-term incentive targets. MPC’s annual bonus program is a critical
component of its compensation, as it provides individual rewards for achievement against preset financial and ESG goals,
encouraging a sense of employee ownership. Employees in the 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.
MPC offers comprehensive benefits that are also benchmarked annually, including medical, dental and vision insurance for
employees, their spouses or domestic partners, and their dependents. MPC also provides retirement programs, life insurance,
education assistance, family assistance, short-term disability and paid vacation and sick time. In addition, MPC provides
generous paid parental leave benefits for birth mothers and nonbirth parents; and, parents who both work for MPC are each
eligible for the benefit. Further, MPC has a substantial accrual cap for vacation banks and also award a significant number of
college and trade school scholarships to the high school senior children of employees through the Marathon Petroleum Scholars
Program. Both full-time and part-time employees are eligible for these benefits.
Inclusion
MPC's 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. The program is based
on a four-pillar DE&I strategy of building awareness, increasing representation, ensuring success, and measurement and
accountability. To execute MPC’s strategy, the near-term action plans are focused on building a diverse workforce, creating a
more inclusive culture, and contributing to our thriving communities.
MPC has employee networks focusing on seven populations: Asian, Black, Disability, Hispanic, LGBTQ+, Veterans, and Women.
MPC’s employee networks have approximately 60 chapters across the company and all networks encourage ally membership.
This broad support extends also to leaders throughout MPC, with each employee network represented by two active executive
sponsors. The sponsors form several counsels that meet regularly to share updates, gain alignment, build deeper connections
across networks and pursue collaboration ideas. The employee networks not only provide opportunities for employees to make
meaningful and supportive connections, but they also serve a significant role in MPC’s 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 units. 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 units could decline. You should not interpret
the disclosure of any risk factor to imply that the risk has not already materialized.

21
Business and Operational Risks
A significant decrease in oil and natural gas production in our areas of operation may adversely affect our business,
financial condition, results of operation and cash available for distribution.
A significant portion of our 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 our producer customers will naturally decline over time, which
means that our cash flows associated with these wells will also decline over time. To maintain or increase throughput levels and
the utilization rate of our facilities, we must continually obtain new oil, natural gas, NGL and refined product supplies, which
depend in part on the level of successful drilling activity near our facilities, our ability to compete for volumes from successful new
wells and our ability to expand our system capacity as needed.
We have no control over the level of drilling activity in the areas of our 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 our areas of operations could lead to reduced throughput on our
pipelines and utilization rates of our facilities.
Decreases in energy prices can decrease drilling activity, production rates and investments by third parties in the development of
new oil and natural gas reserves. The prices for oil, natural gas and NGLs depend upon factors beyond our control, including
global and local demand, production levels, changes in interstate pipeline gas quality specifications, imports and exports,
seasonality and weather conditions, alternative energy sources such as wind, solar and other renewable energy technologies,
economic and political conditions domestically and internationally and governmental regulations. Sustained periods of low prices
could result in producers deciding to limit their oil and gas drilling operations, which could substantially delay the production and
delivery of volumes of oil, natural gas and NGLs to our facilities and adversely affect our revenues and cash available for
distribution.
This impact may also be exacerbated due to the extent of our commodity-based contracts, which are more directly impacted by
changes in natural gas and NGL prices than our 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, our purchase and
resale of gas and NGLs in the ordinary course exposes us to significant risk of 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 our production processes. The significant volatility in
natural gas, NGL and oil prices could adversely impact our unit price, thereby increasing our distribution yield and cost of capital.
Such impacts could adversely impact our ability to execute our long-term organic growth projects, satisfy our obligations to our
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.
We may not always be able to accurately estimate expected production volumes of our producer customers; therefore,
volumes we service in the future could be less than we anticipate.
We may not be able to accurately estimate expected production volumes of our producer customers. Furthermore, we may have
only limited oil, natural gas, NGL or refined product supplies committed to any new facility prior to its construction. We may
construct facilities to capture anticipated future growth in production or satisfy anticipated market demand which does not
materialize, the facilities may not operate as planned or may not be used at all. In order to attract additional oil, natural gas, NGL
or refined product supplies from a customer, we may be required to order equipment and facilities, obtain rights of way or other
land rights or otherwise commence construction activities for facilities that will be required to serve such customer’s additional
supplies prior to executing agreements with the customer. If such agreements are not executed, we may be unable to recover
such costs and expenses. Additionally, new facilities may not be able to attract enough oil, natural gas, NGLs or refined products
to achieve our expected investment return. Alternatively, oil, natural gas, NGL or refined product supplies committed to facilities
under construction may be delivered prior to completion of such facilities, or we may otherwise have unexpected increases in
volumes that could adversely affect our ability to expand our facilities. In such event, we may be required to temporarily utilize
third-party facilities for such oil, natural gas, NGLs or refined products, which may increase our operating costs and reduce our
cash available for distribution.
We depend on third parties for the oil, natural gas and refined products we gather, transport and store, the natural gas
we process, and the NGLs we fractionate and stabilize at our facilities, and a reduction in these quantities could reduce
our revenues and cash flow.
A significant portion of our supply of oil, natural gas, NGLs and refined products comes from a limited number of key producers/
suppliers, who may be under no obligation to deliver a specific volume to our facilities. If any of these significant suppliers, or a
significant number of smaller producers, were to decrease the supply of oil, natural gas, NGLs or refined products to our systems
and facilities for any reason, we could experience difficulty in replacing those lost volumes. In some cases, the producers or
suppliers are responsible for gathering or delivering oil, natural gas, NGLs or refined products to our facilities or we rely on other
22
third parties to deliver volumes to us on behalf of the producers or suppliers. If such producers, suppliers or other third parties
are unable, or otherwise fail to, deliver the volumes to our facilities, or if our agreements with any of these third parties terminate
or expire such that our facilities are no longer connected to their gathering or transportation systems or the third parties modify
the flow of natural gas or NGLs on those systems away from our facilities, the throughput on and utilization of our facilities may
be reduced, or we may be required to incur significant capital expenditures to construct and install gathering pipelines or other
facilities to be able to receive such volumes. Because our operating costs are primarily fixed, a reduction in the volumes
delivered to us would result not only in a reduction of revenues, but also a decline in net income and cash flow.
We may not be able to retain existing customers, or acquire new customers, which would reduce our revenues and limit
our future profitability.
A significant portion of our business comes from a limited number of key customers. The renewal or replacement of existing
contracts with our customers at rates sufficient to maintain current revenues and cash flows depends on a number of factors
beyond our control, including competition from other gatherers, processors, pipelines and fractionators, and the price of, and
demand for, natural gas, NGLs, crude oil and refined products in the markets we serve. Our competitors include large oil, natural
gas, refining and petrochemical companies, some of which have greater financial resources, more numerous or greater capacity
pipelines, processing and other facilities, greater access to natural gas, crude oil and NGL supplies than we do or other
synergies with existing or new customers that we cannot provide. Our competitors may also include our joint venture partners,
who in some cases are permitted to compete with us and may have a competitive advantage due to their familiarity with our
business arising from our joint venture arrangements, as well as third parties on whom we rely to deliver natural gas, NGLs,
crude oil and refined products to our facilities, who may have a competitive advantage due to their ability to modify the flow of
natural gas, NGLs, crude oil and refined products on their systems away from our facilities. Additionally, our customers that
gather gas through facilities that are not otherwise dedicated to us may develop their own processing and fractionation facilities
in lieu of using our services.
As a consequence of the increase in competition in the industry, and the volatility of natural gas prices, end-users and utilities are
reluctant to enter into long-term purchase contracts. Many end-users purchase natural gas from more than one natural gas
company and have the ability to change providers at any time. Some of these end-users also have the ability to switch between
gas and alternative fuels in response to relative price fluctuations in the market. Because there are numerous companies of
greatly varying size and financial capacity that compete with us in the marketing of natural gas, we often compete in the end-user
and utilities markets primarily on the basis of price. The inability of our management to renew or replace our current contracts as
they expire and to respond appropriately to changing market conditions could affect our profitability.
The fees charged to third parties under our gathering, processing, transmission, transportation, fractionation,
stabilization and storage agreements may not escalate sufficiently to cover increases in costs, or the agreements may
not be renewed or may be suspended in some circumstances.
Our costs may increase at a rate greater than the fees we charge to third parties. Furthermore, third parties may not renew their
contracts with us. Additionally, some third parties’ obligations under their agreements with us may be permanently or temporarily
reduced due to certain events, some of which are beyond our control, including force majeure events wherein the supply of
natural gas, NGLs, crude oil or refined products are curtailed or cut-off due to events outside our control, and in some cases,
certain of those agreements may be terminated in their entirety if the duration of such events exceeds a specified period of time.
If the escalation of fees is insufficient to cover increased costs, or if third parties do not renew or extend their contracts with us, or
if third parties suspend or terminate their contracts with us, our financial results would suffer.
The U.S. inland waterway infrastructure is aging and may result in increased costs and disruptions to our operations.
Maintenance of the U.S. inland waterway system is vital to our marine transportation operations. The system is composed of
over 12,000 miles of commercially navigable waterway, supported by approximately 240 locks and dams designed to provide
flood control, maintain pool levels of water in certain areas of the country and facilitate navigation on the inland river system. The
U.S. inland waterway infrastructure is aging, with more than half of the locks over 50 years old. As a result, due to the age of the
locks, planned and unplanned maintenance may create more frequent outages, resulting in delays and additional operating
expenses. Part of the costs for new construction and major rehabilitation of locks and dams is funded by marine transportation
companies through taxes and the other portion is funded by general federal tax revenues. Failure of the federal government to
adequately fund infrastructure maintenance and improvements in the future would have a negative impact on our ability to deliver
products to our customers on a timely basis. Furthermore, any additional user taxes that may be imposed in the future to fund
infrastructure improvements would increase our operating expenses.
Our operations are subject to business interruptions and casualty losses.
Our operations are subject to business interruptions, such as unplanned maintenance, explosions, fires, 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 us. Our customers’ operations, including MPC’s refining operations, are
subject to similar risks.
23
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, environmental pollution, impairment of operations and substantial losses. We and
our customers have experienced certain of these incidents in the past. For assets located near populated areas, the level of
damage resulting from these risks could be greater. Due to the nature of our operations, certain interruptions could impact
operations in other regions.
Our marine transportation business, in particular, is subject to weather conditions. Adverse weather conditions such as high or
low water on the inland waterway systems, fog and ice, tropical storms, hurricanes and tsunamis on both the inland waterway
systems and throughout the U.S. coastal waters can impair the operating efficiencies of the marine fleet. Such adverse weather
conditions can cause a delay, diversion or postponement of shipments of products and are beyond our control.
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. 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. 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.
The construction and operation of certain of our facilities may be impacted by surface or subsurface mining operations by one or
more third parties, which could adversely impact our construction activities or cause subsidence or other damage to our facilities.
In such event, our construction may be prevented or delayed, or the costs and time increased, or our operations at such facilities
may be impaired or interrupted, and we may not be able to recover the costs incurred for delays or to relocate or repair our
facilities from such third parties.
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 transport and store. While demand for the petroleum
products that we 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.
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 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, financial transactions, banking and numerous other processes and transactions.
24
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.
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.
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 terrorist 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.
Many of our assets have been in service for many years and, as a result, our maintenance or repair costs may increase
in the future.
Our pipelines, terminals, fractionator and storage assets are generally long-lived assets, and many of them have been in service
for many years. The age and condition of our assets could result in increased maintenance or repair expenditures in the future.
Any significant increase in these expenditures could adversely affect our results of operations, financial position or cash flows, as
well as our ability to make cash distributions to our unitholders.
Severe weather events, other climate conditions and earth movement and other geological hazards may adversely
affect our and our customers’ assets and ongoing operations.
Our and our customers’ 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, MPC’s Galveston Bay refinery was adversely
affected by Winter Storm Uri and MPC’s 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 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.
25
Financial Risks
We may not have sufficient cash from operations after the establishment of cash reserves and payment of our
expenses, including cost reimbursements to MPC and its affiliates, to enable us to pay the intended quarterly
distribution to our unitholders.
The amount of cash we can distribute to our common unitholders principally depends on the amount of cash we generate from
our operations, which fluctuates from quarter to quarter based on, among other things:
•
•
•
•
•
•
the volumes of natural gas, crude oil, NGLs and refined products we gather, process, store, transport and fractionate;
the fees and tariff rates we charge and the margins we realize for our services and sales;
the prices of, level of production of and demand for oil, natural gas, NGLs and refined products;
the level of our operating costs including repairs and maintenance;
the relative prices of NGLs and crude oil, which impact the effectiveness of our hedging program; and
prevailing economic conditions.
In addition, the actual amount of cash available for distribution also depends on other factors, some of which are beyond our
control, including:
•
•
•
•
•
•
•
•
the amount of our operating expenses and general and administrative expenses, including cost reimbursements to
MPC;
our debt service requirements and other liabilities;
fluctuations in our working capital needs;
our ability to borrow funds and access capital markets;
restrictions in our joint venture agreements or agreements governing our debt;
the level and timing of capital expenditures we make, including capital expenditures incurred in connection with our
enhancement projects;
the cost of acquisitions, if any; and
the amount of cash reserves established by our general partner in its discretion, which may increase in the future and
which may in turn further reduce the amount of cash available for distribution.
Furthermore, the amount of cash we have available for distribution depends primarily on our cash flow and not solely on
profitability, which is affected by non-cash items. As a result, we may make distributions during periods when we record net
losses and may not make distributions during periods when we record net income.
Our substantial debt and other financial obligations could impair our financial condition, results of operations and cash
flow, and our ability to fulfill our debt obligations.
We have significant debt obligations, which totaled $20.1 billion as of December 31, 2022, including amounts, if any, outstanding
under our loan agreement with a wholly owned subsidiary of MPC. We may incur significant debt obligations in the future. Our
indebtedness may impose various restrictions and covenants on us that could have, or the incurrence of such debt could
otherwise result in, material adverse consequences, including:
• We may have difficulties obtaining additional financing for working capital, capital expenditures, acquisitions, or general
business purposes on favorable terms, if at all, or our cost of borrowing may increase.
• We may be at a competitive disadvantage compared to our competitors who have proportionately less debt, or we may
be more vulnerable to, and have limited flexibility to respond to, competitive pressures or a downturn in our business or
the economy generally.
•
•
If our operating results are not sufficient to service our indebtedness, we may be required to reduce our distributions,
reduce or delay our business activities, investments or capital expenditures, sell assets or issue equity, which could
materially and adversely affect our financial condition, results of operations, cash flows and ability to make distributions
to unitholders, as well as the trading price of our common units.
The operating and financial restrictions and covenants in our revolving credit facility and any future financing
agreements could restrict our ability to finance our operations or capital needs or to expand or pursue our business
activities, which may, in turn, limit our ability to make distributions to our unitholders. Our ability to comply with these
covenants may be impaired from time to time if the fluctuations in our working capital needs are not consistent with the
timing for our receipt of funds from our operations.
26
•
If we fail to comply with our debt obligations and an event of default occurs, our lenders could declare the outstanding
principal of that debt, together with accrued interest, to be immediately due and payable, which may trigger defaults
under our other debt instruments or other contracts. Our assets may be insufficient to repay such debt in full, and the
holders of our units could experience a partial or total loss of their investment.
Increases in interest rates could adversely impact our unit price, our ability to issue equity or incur debt for
acquisitions or other purposes and our ability to make distributions at our intended levels.
Our revolving credit facility and our loan agreement with a wholly owned subsidiary of MPC have variable interest rates. 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.
As with other yield-oriented securities, our unit price will be impacted by our cash distributions and the implied distribution yield.
The distribution yield is often used by investors to compare and rank yield-oriented securities for investment decision-making
purposes. Therefore, changes in interest rates, either positive or negative, may affect the yield requirements of investors who
invest in our units, and a rising interest rate environment could have an adverse impact on our unit price and our ability to issue
equity or incur debt for acquisitions or other purposes and to make distributions at our intended levels.
We are exposed to the credit risks of our key customers, and any material non-payment or non-performance by our key
customers could reduce our ability to make distributions to our unitholders.
We are subject to risks of loss resulting from non-payment or non-performance by our customers, which risks may increase
during periods of economic uncertainty. Furthermore, some of our customers may be highly leveraged and subject to their own
operating and regulatory risks, which increases the risk that they may default on their obligations to us. This risk is further
heightened during sustained periods of declines of natural gas, NGL and oil prices. To the extent any of our customers are in
financial distress or commence bankruptcy proceedings, our contracts with them, including provisions relating to dedications of
production, may be subject to renegotiation or rejection under applicable provisions of the United States Bankruptcy Code. If a
contract with a customer is altered or rejected in bankruptcy proceedings, we could lose some or all of the expected revenues
associated with that contract. Any such material non-payment or non-performance could reduce our ability to make distributions
to our unitholders.
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, 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.
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 specific impact of laws and regulations, and their enforcement, on us and our competitors may vary depending on a number
of factors, including the age and location of operating facilities, marketing areas and production processes and subsequent
judicial interpretation of such laws and regulations. We have incurred and will continue to incur substantial capital, operating and
maintenance, and remediation expenditures to modify operations, install pollution control equipment, perform site cleanups or
curtail operations. We may also face liability for personal injury, property damage, natural resource damage or clean-up costs
due to alleged contamination and/or exposure to chemicals such as benzene and MTBE. There is also increased regulatory
interest in PFAS, which we expect will lead to increased monitoring 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. 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.
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.
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 we transport and store.
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 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 MPC,
upon which we depend for a substantial portion of our business. 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 we have a minority interest, has been subject to, and may in the future be subject to, litigation seeking
28
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 MPC’s ability to attract or retain the employees who provide services to us.
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.
Large capital projects may be subject to delays, can take years to complete, and market conditions could deteriorate
significantly between the project approval date and the project startup date, negatively impacting project returns.
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.
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 environmental, social and governance
(“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, we could experience
29
additional costs or financial penalties, delayed or cancelled projects, or adverse unit price impacts, which could have a material
and adverse effect on our business and results of operations.
Our goals, targets and disclosures related to ESG matters expose us to numerous risks, including risks to our
reputation and unit 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, MPLX established a target to reduce methane emissions intensity and
MPC, MPLX’s largest customer, has established a target to reduce GHG emissions. 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 unit 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
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.
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 our 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.
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 our assets are located, 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 obtain and 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 these rights, including
loss or reduction due to legal, governmental or other actions or difficulty renewing leases, right-of-way agreements or permits on
satisfactory terms or at all, could have a material adverse effect on our business, results of operations, financial condition and
ability to make cash distributions to our unitholders.
If foreign investment in us or our general partner exceeds certain levels, we could be prohibited from operating inland
river vessels, which could materially and 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
would be prohibited from operating vessels in the U.S. inland waters. Such a prohibition could materially and adversely affect our
business, financial condition, results of operations and cash flows.
Some of our natural gas, NGL, crude oil and refined product pipelines are subject to FERC’s rate-making policies that
could have an adverse impact on our ability to establish rates that would allow us to recover the full cost of operating
our pipelines including a reasonable return.
30
A number of our pipelines provide interstate service that is subject to regulation by FERC. FERC prescribes rate methodologies
for developing regulated tariff rates for these natural gas, interstate oil and products pipelines. FERC’s regulated tariff may not
allow us to recover all of our costs of providing services. Changes in FERC’s approved rate methodologies, or challenges to our
application of an approved methodology, could also adversely affect our rates. Additionally, shippers may protest (and FERC may
investigate) the lawfulness of tariff rates. FERC can require refunds of amounts collected pursuant to rates that are ultimately
found to be unlawful and prescribe new rates prospectively. Action by FERC could adversely affect our ability to establish
reasonable rates that cover operating costs and allow for a reasonable return. An adverse determination in any future rate
proceeding brought by or against us could have a material adverse effect on our business, financial condition and results of
operations.
Pipelines and operations not subject to regulation by FERC may still be subject to regulation by various state agencies. The
applicable statutes and regulations generally require that our rates and terms and conditions of service provide no more than a
fair return on the aggregate value of the facilities used to render services and that we offer service to our shippers on a not
unduly discriminatory basis. FERC rate cases can involve complex and expensive proceedings. For more information regarding
regulatory matters that could affect our business, please read Item 1. Business – Regulatory Matters as set forth in this Annual
Report on Form 10-K.
We may incur significant costs and liabilities resulting from performance of pipeline integrity programs and related
repairs, and the expansion of pipeline safety laws and regulations could require us to use more comprehensive and
stringent safety controls and subject us to increased capital and operating costs.
The DOT through the PHMSA has adopted regulations requiring pipeline operators to develop integrity management programs
for gas transmission and hazardous liquids pipelines located where a leak or rupture could do the most harm. The regulations
require the following of operators of covered pipelines to:
•
•
•
•
•
perform ongoing assessments of pipeline integrity;
identify and characterize applicable threats to pipeline segments that could impact a high consequence area;
improve data collection, integration and analysis;
repair and remediate the pipeline as necessary; and
implement preventive and mitigating actions.
Some states have adopted regulations similar to existing PHMSA regulations for intrastate gathering and transmission lines. The
adoption of additional laws or regulations that apply more comprehensive or stringent safety standards to gas, NGL, crude oil
and refined product lines or other facilities, or the expansion of regulatory inspections by regulators, could require us to install
new or modified safety controls, pursue added capital projects, make modifications or operational changes, or conduct
maintenance programs on an accelerated basis, all of which could require us to incur increased capital and operational costs or
operational delays that could be significant and have a material adverse effect on our financial position or results of operations
and ability to make distributions to our unitholders.
Transaction Risks
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 in the future.
We accounted for our acquisition of Andeavor Logistics LP (“ANDX” and such acquisition, the “Merger”) as a reorganization of
entities under common control in accordance with accounting principles generally accepted in the United States. Under a
reorganization of entities under common control, the assets and liabilities of ANDX transferred between entities under common
control were recorded by MPLX based on MPC’s historical cost basis resulting from its preliminary purchase price accounting.
We recorded ANDX’s assets and liabilities at MPC’s basis as of October 1, 2018, the date that common control was first
established. Under MPC’s application of the acquisition method of accounting, a portion of the total purchase price was allocated
to ANDX’s tangible assets and liabilities and identifiable intangible assets based on their fair values as of October 1, 2018. The
excess of the allocated purchase price over those fair values was recorded as goodwill.
In 2020, we recorded approximately $2.0 billion in impairment expense related to goodwill and intangible assets. As of December
31, 2022, our balance sheet reflected $7.6 billion and $705 million of goodwill and intangible assets, respectively. To the extent
the value of goodwill or intangible assets becomes further impaired, we may be required to incur additional material non-cash
charges relating to such impairment. Our operating results may be significantly impacted from both the impairment and the
underlying trends in the business that triggered the impairment.
31
If we are unable to make strategic acquisitions on economically acceptable terms from MPC or third parties, our ability
to implement our business strategy may be impaired.
In addition to organic growth, a component of our business strategy can include the expansion of our operations through
strategic acquisitions. If we are unable to make accretive strategic acquisitions from MPC or third parties that increase the cash
generated from operations per unit, whether due to an inability to identify attractive acquisition candidates, to negotiate
acceptable purchase contracts, or to obtain financing for these acquisitions on economically acceptable terms, then our ability to
successfully implement our business strategy may be impaired.
Future acquisitions will involve the integration of new assets or businesses and may present substantial risks that
could adversely affect our business, financial conditions, results of operations and cash flows.
Future transactions involving the addition of new assets or businesses will present potential risks, which may include, among
others:
•
•
•
•
•
•
•
•
inaccurate assumptions about future synergies, revenues, capital expenditures and operating costs;
an inability to successfully integrate, or a delay in the successful integration of, assets or businesses we acquire;
a decrease in our liquidity resulting from using a portion of our available cash or borrowing capacity under our revolving
credit agreement to finance transactions;
a significant increase in our interest expense or financial leverage if we incur additional debt to finance transactions;
the assumption of unknown environmental and other liabilities, losses or costs for which we are not indemnified or for
which our indemnity is inadequate;
the diversion of management’s attention from other business concerns;
the loss of customers or key employees from the acquired businesses; and
the incurrence of other significant charges, such as impairment of goodwill or other intangible assets, asset devaluation
or restructuring charges.
Risks Relating to the Business and Operations of MPC
MPC accounts for a substantial portion of our revenues. If MPC is unable to satisfy its obligations to us or significantly
reduces the volumes transported through our facilities or stored at our storage assets, our revenues would decline and
our financial condition, results of operations, cash flows, and ability to make distributions to our unitholders would be
materially and adversely affected.
We derive a substantial portion of our revenues from MPC. Any event that materially and adversely affects MPC’s financial
condition, results of operations or cash flows may adversely affect our ability to sustain or increase distributions to our
unitholders. Accordingly, we are indirectly subject to the operational and business decisions and risks of MPC, which include the
following:
•
•
•
•
•
the timing and extent of changes in commodity prices and demand for MPC’s products, and the availability and costs of
crude oil and other refinery feedstocks;
a material decrease in the refining margins at MPC’s refineries;
disruptions due to equipment interruption or failure at MPC’s facilities or at third-party facilities on which MPC’s business
is dependent;
any decision by MPC to temporarily or permanently alter, curtail or shut down operations at one or more of its refineries
or other facilities and reduce or terminate its obligations under our transportation and storage or refining logistics and
fuels distribution agreements;
changes to the routing of volumes shipped by MPC on our crude oil and refined product pipelines or the ability of MPC
to utilize third-party pipeline connections to access our pipelines;
• MPC’s ability to remain in compliance with the terms of its outstanding indebtedness;
•
•
•
•
changes in the cost or availability of third-party pipelines, railways, vessels, terminals and other means of delivering and
transporting crude oil, feedstocks, refined products, other hydrocarbon-based products and renewables;
state and federal environmental, economic, health and safety, energy and other policies and regulations, and any
changes in those policies and regulations;
imposition of new economic sanctions against Russia or other countries and the effects of potential responsive
countermeasures;
environmental incidents and violations and related remediation costs, fines and other liabilities;
32
•
•
•
operational hazards and other incidents at MPC’s refineries and other facilities, such as explosions and fires, that result
in temporary or permanent shut downs of those refineries and facilities;
changes in crude oil and refined product inventory levels and carrying costs; and
disruptions due to hurricanes, tornadoes or other forces of nature.
MPC is not obligated to use our services with respect to volumes in excess of the minimum volume commitments under its
agreements with us. If MPC satisfies only its minimum obligations under, or if we are unable to renew or extend, the
transportation, terminal, fuels distribution, marketing and storage services agreements we have with MPC, or if MPC elects to
use credits upon the expiration or termination of an agreement, our cash available for distribution will be materially and adversely
affected.
In addition, significant stockholders of MPC may attempt to effect changes at MPC or acquire control of the company, which
could impact the pursuit of MPC’s business strategies. 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. As a result,
stockholder campaigns at MPC could directly or indirectly adversely affect our results of operations and financial condition and
our ability to sustain or increase distributions to our unitholders.
MPC may suspend, reduce or terminate its obligations under its agreements with us in some circumstances, which
could have a material adverse effect on our financial condition, results of operations, cash flows and ability to make
distributions to our unitholders.
Certain of our transportation, terminal, fuels distribution, marketing and storage services agreements with MPC include
provisions that permit MPC to suspend, reduce or terminate its obligations under the applicable agreement if certain events
occur. These events include a material breach of the applicable agreement by us, MPC being prevented from transporting its full
minimum volume commitment because of capacity constraints on our pipelines, certain force majeure events that would prevent
us from performing some or all of the required services under the applicable agreement and MPC’s determination to suspend
refining operations at one of its refineries. MPC has the discretion to make such decisions notwithstanding the fact that they may
significantly and adversely affect us. These actions could result in a suspension, reduction or termination of MPC’s obligations
under one or more transportation and storage services agreements.
Any such reduction, suspension or termination of MPC’s obligations could have a material adverse effect on our financial
condition, results of operations, cash flows and ability to make distributions to our unitholders.
MPC’s level of indebtedness, the terms of its borrowings and its credit ratings could adversely affect our ability to grow
our business and our ability to make distributions to our unitholders. Our ability to obtain credit in the future may also
be adversely affected by MPC’s credit rating.
MPC must devote a portion of its cash flows from operating activities to service its indebtedness, and therefore, cash flows may
not be available for use in pursuing its growth strategy. Furthermore, a higher level of indebtedness at MPC in the future
increases the risk that it may default on its obligations to us under our transportation and storage services agreements. As of
December 31, 2022, MPC had consolidated long-term indebtedness of approximately $27.1 billion, of which $7.0 billion was a
direct obligation of MPC or its subsidiaries other than MPLX or its consolidated subsidiaries. The covenants contained in the
agreements governing MPC’s outstanding and future indebtedness may limit its ability to borrow additional funds for
development and make certain investments and may directly or indirectly impact our operations in a similar manner.
Furthermore, if MPC were to default under certain of its debt obligations, there is a risk that MPC’s creditors would attempt to
assert claims against our assets during the litigation of their claims against MPC. The defense of any such claims could be costly
and could materially impact our financial condition, even absent any adverse determination. If these claims were successful, our
ability to meet our obligations to our creditors, make distributions and finance our operations could be materially and adversely
affected.
Rating agencies have in the past, and may in the future, change MPLX’s credit ratings or credit outlook following developments
at MPC. If these ratings are lowered in the future, the interest rate and fees MPC pays on its credit facilities may increase. Credit
rating agencies will likely consider MPC’s debt ratings when assigning ours because of MPC’s ownership interest in us, the
significant commercial relationships between MPC and us, and our reliance on MPC for a portion of our revenues. If one or more
credit rating agencies were to downgrade the outstanding indebtedness of us or MPC, we could experience an increase in our
borrowing costs or difficulty accessing the capital markets. Such a development could adversely affect our ability to grow our
business and to make distributions to our unitholders.
Tax Risks
Our tax treatment depends on our status as a partnership for federal income tax purposes as well as our not being
subject to a material amount of entity level taxation by individual states. If the IRS were to treat us as a corporation for
33
federal income tax purposes, or we become subject to a material amount of entity level taxation for state tax purposes,
it would substantially reduce the amount of cash available for distribution to our unitholders.
The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a
partnership for federal income tax purposes. We have not requested, and do not plan to request, a ruling from the IRS on this.
A publicly traded partnership such as us may be treated as a corporation for federal income tax purposes unless it satisfies a
“qualifying income” requirement. Based on our current operations, we believe that we are treated as a partnership rather than as
a corporation for such purposes; however, a change in our business or a change in current law could cause us to be treated as a
corporation for federal income tax purposes. The IRS may adopt positions that differ from the ones we take. A successful IRS
contest of the federal income tax positions we take may adversely impact the market for our common units, and the costs of any
IRS contest will reduce our cash available for distribution to unitholders.
If we were treated as a corporation for federal income tax purposes, we would pay federal income tax on our taxable income at
the corporate tax rate, which is currently a maximum of 21 percent, and likely would pay state and local income tax at varying
rates. Distributions to unitholders generally would be taxed again as corporate dividends, and no income, gains, losses,
deductions, or credits would flow through to our unitholders. Treatment of us as a corporation would result in a material reduction
in the anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our
common units. Changes in current state or local law may subject us to additional entity-level taxation by individual states and
localities. For example, we are currently subject to state and local taxes in Texas and Tennessee and certain localities in
Kentucky, Michigan and Ohio. Imposition of any such additional taxes on us may substantially reduce the cash available for
distribution to unitholders.
Our Partnership Agreement provides that, if a law is enacted or an existing law is modified or interpreted in a manner that
subjects us to taxation as a corporation or otherwise subjects us to entity-level taxation for federal, state or local income tax
purposes, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of
that law on us.
If the IRS contests the federal income tax positions we take, the market for our common units may be adversely
impacted and the cost of any IRS contest will reduce our cash available for distribution.
The IRS has made no determination as to our status as a partnership for federal income tax purposes. The IRS may adopt
positions that differ from the positions we take. It may be necessary to resort to administrative or court proceedings to sustain
some or all the positions we take. A court may not agree with some or all of the positions we take. Any contest with the IRS may
materially and adversely impact the market for our common units and the price at which they trade. In addition, our costs of any
contest with the IRS will be borne indirectly by our unitholders and our general partner because the costs will reduce our cash
available for distribution.
Our unitholders will be required to pay taxes on their share of income even if they do not receive any distributions from
us.
Because our unitholders will be treated as partners to whom we will allocate taxable income that could be different in amount
than the cash we distribute, our unitholders will be required to pay any federal income taxes and, in some cases, state and local
income taxes on their share of our taxable income even if they receive no distributions from us. Our unitholders may not receive
distributions from us equal to their share of our taxable income or even equal to the actual tax liability that result from that
income.
Tax gain or loss on the disposition of our common units could be more or less than expected.
If our unitholders sell their common units, they will recognize gain or loss equal to the difference between the amount realized
and their tax basis in those common units. Because distributions in excess of a unitholder’s allocable share of our net taxable
income decrease the unitholder’s tax basis in their common units, the amount, if any, of such prior excess distributions with
respect to their units will, in effect, increase taxable income to the unitholder. Furthermore, a substantial portion of the amount
realized, whether or not representing gain, may be taxed as ordinary income due to potential recapture items, including
depreciation recapture. In addition, because the amount realized includes a unitholder’s share of our non-recourse liabilities, if a
unitholder sells units, the unitholder may incur taxable income in excess of the amount of cash received from the sale.
Tax-exempt entities face unique tax issues from owning our common units that may result in adverse tax
consequences to them.
Investment in our common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts
(known as IRAs), raises issues unique to them. For example, virtually all of our income allocated to organizations that are
exempt from federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be
taxable to them. Furthermore, a tax-exempt entity’s gain on sale of common units may be treated, at least in part, as unrelated
business taxable income. Tax-exempt entities should consult their tax advisor before investing in our common units.
34
Non-U.S. unitholders will be subject to United States taxes and withholding with respect to their income and gain from
owning our units.
Non-U.S. unitholders are generally taxed and subject to income tax filing requirements by the United States on income effectively
connected with a U.S. trade or business. Income allocated to our unitholders and any gain from the sale of our units will
generally be considered to be “effectively connected” with a U.S. trade or business. As a result, distributions to non-U.S. persons
will be reduced by withholding taxes at the highest applicable effective tax rate, and non-U.S. persons will be required to file U.S.
federal tax returns and pay tax on their share of our taxable income. Non-U.S. persons will also potentially have tax filings and
payment obligations in additional jurisdictions.
We treat each purchaser of common units as having the same tax benefits without regard to the actual units purchased.
The IRS may challenge this treatment, which could adversely affect the value of the common units.
Because we cannot match transferors and transferees of common units and to enable the uniformity of the economic and tax
characteristics of common units, we have adopted depreciation and amortization positions that may not conform to all aspects of
existing Treasury Regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits
available to our unitholders. It also could affect the timing of these tax benefits or the amount of gain from the sale of common
units and could have a negative impact on the value of our common units or result in audit adjustments to our unitholders’ tax
returns.
Our unitholders will likely be subject to state and local taxes and return filing requirements in states where they do not
live as a result of investing in our units.
In addition to federal income taxes, our unitholders will likely be subject to other taxes, including state and local taxes,
unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which
we do business or own property now or in the future, even if our unitholders do not live in any of those jurisdictions. Our
unitholders will likely be required to file state and local income tax returns and pay state and local income taxes in some or all of
these various jurisdictions. Further, our unitholders may be subject to penalties for failure to comply with those requirements. We
currently conduct business in a substantial number of states, most of which currently impose a personal income tax and many of
which impose an income tax on corporations and other entities. As we make acquisitions or expand our business, we may own
assets or conduct business in additional states. It is our unitholders’ responsibility to file all U.S. federal, state and local tax
returns.
We have adopted certain valuation methodologies that may result in a shift of income, gain, loss and deduction
between our general partner and our unitholders. The IRS may challenge this treatment, which could adversely affect
the value of the common units.
When we issue additional units or engage in certain other transactions, we must determine the fair market value of our assets
and allocate any unrealized gain or loss attributable to our assets to the capital accounts of our unitholders and our general
partner. Our methodology may be viewed as understating the value of our assets. In that case, there may be a shift of income,
gain, loss and deduction between certain unitholders and the general partner, which may be unfavorable to such unitholders.
Moreover, under our valuation methods, subsequent purchasers of common units may have a greater portion of their Internal
Revenue Code Section 743(b) adjustment allocated to our tangible assets and a lesser portion allocated to our intangible assets.
The IRS may challenge our valuation methods, our allocation of the Section 743(b) adjustment attributable to our tangible and
intangible assets, or our allocations of income, gain, loss and deduction between our general partner and certain of our
unitholders.
A successful IRS challenge to these methods or allocations could adversely affect the amount of taxable income or loss being
allocated to our unitholders. It also could affect the amount of gain from our unitholders’ sale of common units and could have a
negative impact on the value of the common units or result in audit adjustments to our unitholders’ tax returns without the benefit
of additional deductions.
A unitholder whose common units are the subject of a securities loan (e.g., a loan to a short seller) may be considered
as having disposed of those common units. If so, the unitholder would no longer be treated for tax purposes as a
partner with respect to those common units during the period of the loan and may recognize gain or loss from the
disposition.
A unitholder whose common units are the subject of a securities loan (i) may be considered as having disposed of the loaned
common units, (ii) may no longer be treated for tax purposes as a partner with respect to those common units during the period
of the loan to the short seller and (iii) may recognize gain or loss from such disposition.
Moreover, during the period of the loan, any of our income, gain, loss or deduction with respect to those common units may not
be reportable by the unitholder and any distributions received by the unitholder as to those common units could be fully taxable
as ordinary income. Unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a securities
35
loan are urged to consult a tax adviser to discuss whether it is advisable to modify any applicable brokerage account agreements
to prohibit their brokers from borrowing their common units.
The tax treatment of publicly traded partnerships or an investment in our 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 us, or an investment in our 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 our 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 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.
We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units
each month based upon the ownership of our units on the first day of each month, instead of on the basis of the date a
particular unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of
income, gain, loss and deduction among our unitholders.
We generally prorate our items of income, gain, loss and deduction between existing unitholders and unitholders who purchase
our units based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular
unit is transferred. Similarly, we generally allocate certain deductions for depreciation of capital additions, gain or loss realized on
a sale or other disposition of our assets and, in the discretion of our general partner, any other extraordinary item of income,
gain, loss or deduction based upon ownership on the allocation date. Treasury Regulations allow a similar monthly simplifying
convention, but such regulations do not specifically authorize all aspects of the proration method we have adopted. If the IRS
were to challenge our proration method or new Treasury Regulations were issued, we may be required to change the allocation
of items of income, gain, loss and deduction among our unitholders.
Unitholders may be subject to limitations on their ability to deduct interest expense we incur.
In general, we are entitled to a deduction for interest paid or accrued on indebtedness properly allocable to our trade or business
during our taxable year. However, subject to the exceptions in the Coronavirus Aid, Relief, and Economic Security Act (the
“CARES Act”) discussed below, under the Tax Cuts and Jobs Act, for taxable years beginning after December 31, 2017, our
deduction for “business interest” is limited to the sum of our business interest income and 30% of our “adjusted taxable income.”
For the purposes of this limitation, our adjusted taxable income is computed without regard to any business interest expense or
business interest income, and in the case of taxable years beginning before January 1, 2022.
If our “business interest” is subject to limitation under these rules, our unitholders will be limited in their ability to deduct their
share of any interest expense that has been allocated to them. As a result, unitholders may be subject to limitation on their ability
to deduct interest expense incurred by us.
If the IRS makes audit adjustments to our income tax returns for tax years beginning after 2017, it (and some states)
may collect any resulting taxes (including any applicable penalties and interest) directly from us, in which case our
cash available for distribution to our unitholders might be substantially reduced.
If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it (and some
states) may collect any resulting taxes (including any applicable penalties and interest) directly from us. We will generally have
certain limited rights to shift any such tax liability to our general partner and our unitholders in accordance with their interests in
us during the year under audit, but there can be no assurance that we will be able to do so (or choose to do so) under all
circumstances. As a result, our current unitholders may bear some or all of the tax liability resulting from such audit adjustment,
even if such unitholders did not own units in us during the tax year under audit. If we are required to make payments of taxes,
penalties and interest resulting from audit adjustments, our cash available for distribution to our unitholders might be reduced.
Common Unit Ownership Risks
Our general partner and its affiliates, including MPC, have conflicts of interest with us and limited duties to us and our
unitholders, and they may favor their own interests to our detriment and that of our unitholders. Additionally, we have
no control over MPC’s business decisions and operations, and MPC is under no obligation to adopt a business strategy
that favors us.
MPC owns our general partner and approximately 65 percent of our outstanding common units as of February 16, 2023.
Although our general partner has a duty to manage us in a manner that is not adverse to the best interests of our partnership,
36
conflicts of interest may arise between MPC and its affiliates, including our general partner, on the one hand, and us and our
unitholders, on the other hand. In resolving these conflicts, the general partner may favor its own interests and the interests of its
affiliates, including MPC, over the interests of our common unitholders, which may occur under our Partnership Agreement
without being independently reviewed by the conflicts committee. These conflicts include, among others, the following situations:
•
neither our Partnership Agreement nor any other agreement requires MPC to pursue a business strategy that favors us
or utilizes our assets, which could involve decisions by MPC to increase or decrease refinery production, shut down or
reconfigure a refinery, or pursue and grow particular markets;
• MPC’s directors and officers have a fiduciary duty to make decisions in the best interests of the stockholders of MPC;
•
disputes may arise under agreements pursuant to which MPC and its affiliates are our customers;
• MPC may be constrained by the terms of its debt instruments from taking actions, or refraining from taking actions, that
may be in our best interests;
•
•
•
•
•
•
•
•
•
•
•
except in limited circumstances, our general partner has the power and authority to conduct our business without
unitholder approval;
our general partner will determine the amount and timing of asset purchases and sales, borrowings, issuance of
additional partnership securities and the creation, reduction or increase of cash reserves, each of which can affect the
amount of cash that is distributed to our unitholders;
our general partner will determine the amount and timing of many of our cash expenditures and whether a cash
expenditure is classified as an expansion capital expenditure, which would not reduce operating surplus, or a
maintenance capital expenditure, which would reduce our operating surplus. This determination can affect the amount
of cash that is distributed to our unitholders, including MPC, and the amount of adjusted operating surplus generated in
any given period;
our general partner will determine which costs incurred by it are reimbursable by us and may cause us to pay it or its
affiliates for any services rendered to us;
our general partner may cause us to borrow funds in order to permit the payment of distributions;
our Partnership Agreement permits us to classify up to $60 million as operating surplus, even if it is generated from
asset sales, non-working capital borrowings or other sources that would otherwise constitute capital surplus. This cash
may be used to fund distributions to our unitholders, including MPC;
our Partnership Agreement does not restrict our general partner from entering into additional contractual arrangements
with it or its affiliates on our behalf;
our general partner intends to limit its liability regarding our contractual and other obligations;
our general partner may exercise its right to call and purchase all of the common units not owned by it and its affiliates if
it and its affiliates own more than 85 percent of the common units;
our general partner controls the enforcement of obligations owed to us by our general partner and its affiliates, including
our transportation and storage services agreements with MPC; and
our general partner decides whether to retain separate counsel, accountants or others to perform services for us.
Under the terms of our Partnership Agreement, the doctrine of corporate opportunity, or any analogous doctrine, does not apply
to our general partner or any of its affiliates, including its executive officers, directors and owners.
Any such person or entity that becomes aware of a potential transaction, agreement, arrangement or other matter that may be an
opportunity for us will not have any duty to communicate or offer such opportunity to us. Any such person or entity will not be
liable to us or to any limited partner for breach of any fiduciary duty or other duty by reason of the fact that such person or entity
pursues or acquires such opportunity for itself, directs such opportunity to another person or entity or does not communicate
such opportunity or information to us. This may create actual and potential conflicts of interest between us and affiliates of our
general partner and result in less than favorable treatment of us and our unitholders.
Our Partnership Agreement requires that we distribute all of our available cash, which could limit our ability to grow
and make acquisitions.
Our Partnership Agreement requires that we distribute all of our available cash to our unitholders. As a result, we may require
external financing sources, including commercial bank borrowings and the issuance of debt and equity securities, to fund our
acquisitions and expansion capital expenditures. Therefore, to the extent we are unable to finance our growth externally, our
cash distribution policy will significantly impair our ability to grow. In addition, because we will distribute all of our available cash,
our growth may not be as fast as that of businesses that reinvest their available cash to expand ongoing operations. To the
extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of
distributions on those additional units may increase the risk that we will be unable to maintain or increase our per unit distribution
37
level. The incurrence of additional commercial borrowings or other debt to finance our growth strategy would result in increased
interest expense, which, in turn, may reduce the amount of cash available to distribute to our unitholders.
Our Partnership Agreement replaces our general partner’s fiduciary duties to holders of our common units with
contractual standards governing its duties and restricts the remedies available to unitholders for actions taken by our
general partner.
Our Partnership Agreement contains provisions that eliminate the fiduciary standards to which our general partner would
otherwise be held by state fiduciary duty law and replaces those duties with several different contractual standards. For example,
our Partnership Agreement permits our general partner to make a number of decisions in its individual capacity, as opposed to in
its capacity as our general partner, free of any duties to us and our unitholders other than the implied contractual covenant of
good faith and fair dealing. Our general partner is entitled to consider only the interests and factors that it desires and is relieved
of any duty or obligation to give consideration to any interest of, or factors affecting, us, our affiliates or our limited partners.
Our Partnership Agreement contains provisions that restrict the remedies available to unitholders for actions taken by our general
partner that might otherwise constitute breaches of fiduciary duty under state fiduciary duty law. For example, our Partnership
Agreement:
•
•
•
•
provides that whenever our general partner makes a determination or takes, or declines to take, any other action in its
capacity as our general partner, our general partner is required to make such determination, or take or decline to take
such other action, in good faith and will not be subject to any other or different standard imposed by our Partnership
Agreement, Delaware law, or any other law, rule or regulation, or at equity;
provides that our general partner will not have any liability to us or our unitholders for decisions made in its capacity as
a general partner so long as it acted in good faith;
provides that our general partner and its officers and directors will not be liable for monetary damages to us or our
limited partners resulting from any act or omission unless there has been a final and non-appealable judgment entered
by a court of competent jurisdiction determining that our general partner or its officers and directors, as the case may
be, acted in bad faith or engaged in fraud or willful misconduct or, in the case of a criminal matter, acted with knowledge
that the conduct was criminal; and
provides that our general partner will not be in breach of its obligations under our Partnership Agreement or its fiduciary
duties to us or our limited partners if a transaction with an affiliate or the resolution of a conflict of interest is approved in
accordance with, or otherwise meets the standards set forth in, our Partnership Agreement.
In connection with a transaction with an affiliate or a conflict of interest, our Partnership Agreement provides that any
determination by our general partner must be made in good faith, and that our conflicts committee and the board of directors of
our general partner are entitled to a presumption that they acted in good faith. In any proceeding brought by or on behalf of any
limited partner or the partnership, the person bringing or prosecuting such proceeding will have the burden of overcoming such
presumption. By purchasing a common unit, a unitholder is treated as having consented to the provisions in our Partnership
Agreement, including the provisions discussed above.
Unitholders have very limited voting rights and, even if they are dissatisfied, they have limited ability to remove our
general partner without its consent.
Unlike the holders of common stock in a corporation, unitholders have only limited voting rights on matters affecting our business
and, therefore, limited ability to influence management’s decisions regarding our business. Unitholders did not elect our general
partner or the board of directors of our general partner and will have no right to elect our general partner or the board of directors
of our general partner on an annual or other continuing basis. The board of directors of our general partner is chosen by the
members of our general partner, which are wholly owned subsidiaries of MPC. Furthermore, if the unitholders are dissatisfied
with the performance of our general partner, they will have little ability to remove our general partner. The vote of the holders of
at least 66 2/3 percent of all outstanding common units voting together as a single class is required to remove our general
partner. As of February 16, 2023, our general partner and its affiliates owned approximately 65 percent of the outstanding
common units (excluding common units held by officers and directors of our general partner and MPC). As a result of these
limitations, the price at which our common units will trade could be diminished because of the absence or reduction of a takeover
premium in the trading price.
Furthermore, unitholders’ voting rights are further restricted by the Partnership Agreement provision providing that any units held
by a person that owns 20 percent or more of any class of units then outstanding, other than our general partner, its affiliates, their
transferees, and persons who acquired such units with the prior approval of the board of directors of our general partner, cannot
vote on any matter.
Our Partnership Agreement also contains provisions limiting the ability of unitholders to call meetings or to acquire information
about our operations, as well as other provisions limiting the unitholders’ ability to influence the manner or direction of
management.
38
If unitholders are not both citizenship-eligible holders and rate-eligible holders, their common units may be subject to
redemption.
In order to avoid (1) any material adverse effect on the maximum applicable rates that can be charged to customers by our
subsidiaries on assets that are subject to rate regulation by the FERC or analogous regulatory body and (2) any substantial risk
of cancellation or forfeiture of any property, including any governmental permit, endorsement or other authorization, in which we
have an interest, we have adopted certain requirements regarding those investors who may own our common units. Citizenship
eligible holders are individuals or entities whose nationality, citizenship or other related status does not create a substantial risk
of cancellation or forfeiture of any property, including any governmental permit, endorsement or authorization, in which we have
an interest, and will generally include individuals and entities who are U.S. citizens. Rate-eligible holders are individuals or
entities subject to U.S. federal income taxation on the income generated by us or entities not subject to U.S. federal income
taxation on the income generated by us, so long as all of the entity’s owners are subject to such taxation. If unitholders are not
persons who meet the requirements to be citizenship-eligible holders and rate-eligible holders, they run the risk of having their
units redeemed by us at the market price as of the date three days before the date the notice of redemption is mailed. The
redemption price will be paid in cash or by delivery of a promissory note, as determined by our general partner. In addition, if
unitholders are not persons who meet the requirements to be citizenship eligible holders, they will not be entitled to voting rights.
Cost reimbursements, which will be determined in our general partner’s sole discretion, and fees due our general
partner and its affiliates for services provided will be substantial and will reduce our cash available for distribution.
Under our Partnership Agreement, we are required to reimburse our general partner and its affiliates for all costs and expenses
that they incur on our behalf for managing and controlling our business and operations. Except to the extent specified under our
omnibus agreements or our employee services agreements, our general partner determines the amount of these expenses.
Under the terms of the omnibus agreements, we will be required to reimburse MPC for the provision of certain general and
administrative services to us. Under the terms of our employee services agreements, we have agreed to reimburse MPC or its
affiliates for the provision of certain operational and management services to us in support of our facilities. Our general partner
and its affiliates also may provide us other services for which we will be charged fees as determined by our general partner.
Payments to our general partner and its affiliates are substantial and reduce the amount of cash available for distribution to
unitholders.
The control of our general partner may be transferred to a third party without unitholder consent.
There is no restriction in our Partnership Agreement on the ability of MPC to transfer its membership interest in our general
partner to a third party. The new members of our general partner would then be in a position to replace the board of directors and
officers of our general partner with their own choices and to control the decisions taken by our general partner.
We may issue additional units without unitholder approval, which will dilute limited unitholder interests.
At any time, we may issue an unlimited number of limited partner interests of any type, including limited partner interests that are
convertible into our common units, without the approval of our unitholders and our unitholders will have no preemptive or other
rights (solely as a result of their status as unitholders) to purchase any such limited partner interests. Further, neither our
Partnership Agreement nor our bank revolving credit facility prohibits the issuance of additional preferred units, or other equity
securities that may effectively rank senior to our common units as to distributions or liquidations. The issuance by us of additional
common units, preferred units or other equity securities of equal or senior rank will have the following effects:
•
•
•
•
•
our unitholders’ proportionate ownership interest in us will decrease;
it may be more difficult to maintain or increase our distributions to unitholders, and the amount of cash available for
distribution on each unit may decrease;
the ratio of taxable income to distributions may increase;
the relative voting strength of each previously outstanding unit may be diminished; and
the market price of our common units may decline.
MPC may sell units in the public or private markets, and such sales could have an adverse impact on the trading price
of the common units.
As of February 16, 2023, MPC held 647,415,452 common units. Additionally, we have agreed to provide MPC with certain
registration rights. The sale of these units in the public or private markets could have an adverse impact on the price of the
common units or on any trading market that may develop.
39
Affiliates of our general partner, including MPC, may compete with us, and neither our general partner nor its affiliates
have any obligation to present business opportunities to us.
MPC and other affiliates of our general partner are not prohibited from owning assets or engaging in businesses that compete
directly or indirectly with us. In addition, MPC and other affiliates of our general partner may acquire, construct or dispose of
additional midstream assets in the future without any obligation to offer us the opportunity to purchase any of those assets. As a
result, competition from MPC and other affiliates of our general partner could materially and adversely impact our results of
operations and cash available for distribution to unitholders.
Our general partner has a limited call right that may require unitholders to sell common units at an undesirable time or
price.
If at any time our general partner and its affiliates own more than 85 percent of our common units, our general partner will have
the right, but not the obligation, which it may assign to any of its affiliates or to us, to acquire all, but not less than all, of the
common units held by unaffiliated persons at a price not less than their then current market price. As a result, unitholders may be
required to sell their common units at an undesirable time or price and may not receive any return on their investment.
Unitholders may also incur a tax liability upon a sale of such units.
A unitholder’s liability may not be limited if a court finds that unitholder action constitutes control of our business.
A general partner of a partnership generally has unlimited liability for the obligations of the partnership, except for those
contractual obligations of the partnership that are expressly made non-recourse to the general partner. Our partnership is
organized under Delaware law, and we conduct business in a number of other states. The limitations on the liability of holders of
limited partner interests for the obligations of a limited partnership have not been clearly established in some jurisdictions. A
unitholder could be liable for our obligations as if they were a general partner if a court or government agency were to determine
that:
•
•
we were conducting business in a state but had not complied with that particular state’s partnership statute; or
a unitholder’s right to act with other unitholders to remove or replace the general partner, to approve some amendments
to our Partnership Agreement or to take other actions under our Partnership Agreement constitute “control” of our
business.
Unitholders may have to repay distributions that were wrongfully distributed to them.
Under certain circumstances, unitholders may have to repay amounts wrongfully distributed to them. Under Section 17-607 of
the Delaware Revised Uniform Limited Partnership Act, we may not make a distribution to unitholders if the distribution would
cause our liabilities to exceed the fair value of our assets. Delaware law provides that for a period of three years from the date of
the impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it
violated Delaware law will be liable to the limited partnership for the distribution amount. Transferees of common units are liable
for the obligations of the transferor to make contributions to the partnership that are known to the transferee at the time of the
transfer and for unknown obligations if the liabilities could be determined from our Partnership Agreement. Liabilities to partners
on account of their partnership interest and liabilities that are non-recourse to the partnership are not counted for purposes of
determining whether a distribution is permitted.
The NYSE does not require a publicly traded limited partnership like us to comply with certain of its corporate
governance requirements.
We list our common units on the NYSE. Because we are a publicly traded limited partnership, the NYSE does not require us to
have a majority of independent directors on our general partner’s board of directors or to establish a compensation committee or
a nominating and corporate governance committee. Accordingly, unitholders will not have the same protections afforded to
certain corporations that are subject to all of the NYSE corporate governance requirements.
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 limited partners.
Our limited partnership agreement provides that the Court of Chancery of the State of Delaware will be the sole and exclusive
forum for any claims, actions or proceedings:
•
•
•
arising out of or relating in any way to our limited partnership agreement, or the rights or powers of, or restrictions on,
our limited partners or the limited partnership;
brought in a derivative manner on behalf of the limited partnership;
asserting a claim of breach of a duty owed by any director, officer, or other employee of the limited partnership or the
general partner, or owed by the general partner, to the partnership or the limited partners;
40
•
•
asserting a claim arising pursuant to any provision of the Delaware Revised Uniform Limited Partnership Act; or
asserting a claim governed by the internal affairs doctrine.
The forum selection provision may restrict a limited partner's ability to bring a claim against us or directors, officers or other
employee of ours or our general partner in a forum that it finds favorable, which may discourage limited partners from bringing
such claims at all. Alternatively, if a court were to find the forum selection provision contained in our limited partnership
agreement 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.

Our crude oil pipeline and related assets are strategically positioned to support diverse and flexible crude oil supply options for
MPC’s refineries, which receive imported and domestic crude oil through a variety of sources. Imported and domestic crude oil is
transported to supply hubs from a variety of regions, including: Cushing, Oklahoma; Western Canada; Wyoming; North Dakota;
the Gulf Coast and Patoka, Illinois. Crude oil pipelines from the Delaware and Midland Basins, as well as from the Bakken region
41
transport crude oil into major regional takeaway pipelines and refining centers. Our major crude oil pipelines are connected to
these supply hubs and transport crude oil to refineries owned by MPC and third parties.
Our pipelines are strategically positioned to supply feedstocks to MPC refineries and transport products from certain MPC
refineries to MPC and MPLX operations, as well as those of third parties. Our refined product pipelines are integrated with MPC’s
and MPLX’s expansive network of refined product terminals, which support MPC’s integrated business.

Title to Properties
We believe that our properties and facilities are adequate for our operations and that our facilities are adequately maintained.
Substantially all of our pipelines are constructed on rights-of-way granted by the apparent record owners of the property. In many
instances, lands over which pipeline rights-of-way have been obtained may be subject to prior liens that have not been
subordinated to the right-of-way grants, as well as potential conflicts with other mineral or surface use owners. We have
obtained, where determined necessary, permits, leases, license agreements and franchise ordinances from public authorities to
cross over or under, or to lay facilities in or along water courses, county roads, municipal streets and state highways, as
applicable. We also have obtained easements and license agreements from railroad companies to cross over or under railroad
properties or rights-of-way. Some of the property rights we have obtained are revocable at the election of the grantor. In addition,
our L&S segment leases vehicles, building spaces, and pipeline equipment under long-term operating leases, most of which
include renewal options. Many of our compression, processing, fractionation and other facilities, including certain fractionation
plants and certain of our pipelines and other facilities, are on land that we either own in fee or that is held under long-term leases.
For any such facilities that are on land that we lease, we could be required to remove our facilities upon the termination or
expiration of the leases.
Some of the leases, easements, rights-of-way, permits, licenses and franchise ordinances that were transferred to us required
the consent of the then-current landowner to transfer these rights, which in some instances was a governmental entity. We
45
believe that we have obtained sufficient third-party consents, permits and authorizations for the transfer of the assets necessary
for us to operate our business. We also believe we have satisfactory title or other right to our material land assets. Title to these
properties is subject to encumbrances in some cases, such as coal, that may require payment to other holders of title in the
property at issue; however, we believe that none of these burdens will materially detract from the value of these properties or
from our interest in these properties, or will materially interfere with their use in the operation of our business. See Item 8.
Financial Statements and Supplementary Data – Note 20, for additional information regarding our leases.
MPC indemnifies us for certain title defects and for failures to obtain certain consents and permits necessary to conduct our
business with respect to the assets contributed to us by MPC. Although title to these properties is subject to encumbrances in
some cases, such as customary interests generally retained in connection with acquisition of real property, liens that can be
imposed in some jurisdictions for government-initiated action to clean up environmental contamination, liens for current taxes
and other burdens, and easements, restrictions and other encumbrances to which the underlying properties were subject at the
time of acquisition. We believe that none of these burdens should materially detract from the value of these properties or from
our interest in these properties or should materially interfere with their use in the operation of our business.
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.
Dakota Access Pipeline
We hold 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.
We have entered into a Contingent Equity Contribution Agreement whereby MPLX LP, along with the other joint venture owners
in the Bakken Pipeline system, has agreed to make equity contributions to the joint venture upon certain events occurring to
allow the entities that own and operate the Bakken Pipeline system to satisfy their senior note payment obligations. The senior
notes were issued to repay amounts owed by the pipeline companies to fund the cost of construction of the Bakken Pipeline
system.
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 one percent 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
46
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.
Gathering and Processing
We have 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. We are in the process of finalizing a settlement with the EPA pursuant to
which we expect 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 to finalize the settlement 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 LP, 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 adverse effect on our consolidated results of
operations, financial position or cash flows.
Item 4. Mine Safety Disclosure

MPLX OVERVIEW
We are a diversified, large-cap MLP formed by MPC in 2012 that owns and operates midstream energy infrastructure and
logistics assets, and provides fuels distribution services. Our assets include a network of crude oil and refined product pipelines;
an inland marine business; light-product, asphalt, heavy oil and marine terminals; storage caverns; refinery tanks, docks, loading
racks, and associated piping; crude oil and natural gas gathering systems and pipelines; as well as natural gas and NGL
processing and fractionation facilities. The business consists of two segments based on the nature of services it offers: Logistics
and Storage (“L&S”) and Gathering and Processing (“G&P”). Our assets are positioned throughout the United States. The L&S
segment primarily engages in the gathering, transportation, storage and distribution of crude oil, refined products, other
hydrocarbon-based products, and renewables. The L&S segment also includes the operation of our refining logistics, fuels
distribution and inland marine businesses, terminals, rail facilities and storage caverns. The G&P segment provides gathering,
processing and transportation of natural gas as well as the transportation, fractionation, storage and marketing of NGLs.

Generated $5.0 billion of net cash provided by operating activities, $5.0 billion of distributable cash flow attributable to
MPLX, and $4.1 billion of adjusted free cash flow.
Paid over $3.0 billion in distributions during the year ended December 31, 2022, which includes a 10 percent increase in our
quarterly distribution effective for the third quarter of 2022, in line with our commitment to return capital to unitholders.
During the year ended December 31, 2022, we returned $491 million to unitholders through the repurchase of over 15
million public common units under our unit repurchase programs. As of December 31, 2022, $846 million remained available
under the unit repurchase authorization.
Renewed pipeline transportation service contracts with MPC, which were set to expire in 2022, extending the term by 10
years.
At December 31, 2022 we had approximately $20.1 billion of total debt (excluding debt issuance costs) and a leverage ratio
of 3.5 to 1.0.
Current Economic Environment
Throughout 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
improved throughputs and higher natural gas and NGL prices. 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. We have observed higher costs for labor and materials
used in our business. We cannot predict the effect of rising interest rates, the concern of a recession, and higher inflation and
fuel prices on demand for our products and services. In response to this business environment, MPLX remains focused on
executing its strategic priorities of strict capital discipline, fostering a low-cost culture, and portfolio optimization. To the extent
permitted by competition, regulation and our existing agreements, many of which provide for inflation-based adjustments, we
have and expect to continue to pass along a portion of increased costs to our customers in the form of higher fees.
NON-GAAP FINANCIAL INFORMATION
Our management uses a variety of financial and operating metrics to analyze our performance. These metrics are significant
factors in assessing our operating results and profitability and include the non-GAAP financial measures of Adjusted EBITDA,
DCF, adjusted free cash flow (“Adjusted FCF”), Adjusted FCF after distributions, and consolidated total debt to last twelve
months Adjusted EBITDA, which we refer to as our leverage ratio. The amount of Adjusted EBITDA and DCF generated is
considered by the board of directors of our general partner in approving MPLX’s cash distributions.
We define Adjusted EBITDA as net income adjusted for: (i) provision for income taxes; (ii) interest and other financial costs; (iii)
depreciation and amortization; (iv) income/(loss) from equity method investments; (v) distributions and adjustments related to
equity method investments; (vi) gain on sales-type leases; (vii) impairment expense; (viii) restructuring expenses (ix)
noncontrolling interests; and (x) other adjustments as deemed necessary. We also use DCF, which we define as Adjusted
EBITDA adjusted for: (i) deferred revenue impacts; (ii) sales-type lease payments, net of income; (iii) net interest and other
financial costs; (iv) net maintenance capital expenditures; (v) equity method investment capital expenditures paid out; (vi)
restructuring expenses; and (vii) other adjustments as deemed necessary.
We define Adjusted FCF as net cash provided by operating activities adjusted for: (i) net cash used in investing activities; (ii)
cash contributions from MPC; and (iii) cash distributions to noncontrolling interests. We define Adjusted FCF after distributions as
Adjusted FCF less base distributions to common and preferred unitholders.
Leverage ratio is a liquidity measure used by management, industry analysts, investors, lenders and rating agencies to analyze
our ability to incur and service debt and fund capital expenditures. Leverage ratio is calculated using consolidated total debt
which excludes unamortized debt issuance costs and unamortized discount/premium. Consolidated total debt includes long-term
debt due within one year and outstanding borrowings under the loan agreement with MPC.
We believe that the presentation of Adjusted EBITDA, DCF, Adjusted FCF and Adjusted FCF after distributions provides useful
information to investors in assessing our financial condition and results of operations. The GAAP measures most directly
comparable to Adjusted EBITDA and DCF are net income and net cash provided by operating activities while the GAAP measure
49
most directly comparable to Adjusted FCF and Adjusted FCF after distributions is net cash provided by operating activities.
These non-GAAP financial measures should not be considered alternatives to GAAP net income or net cash provided by
operating activities as they have important limitations as analytical tools because they exclude some but not all items that affect
net income and net cash provided by operating activities or any other measure of financial performance or liquidity presented in
accordance with GAAP. These non-GAAP financial measures should not be considered in isolation or as substitutes for analysis
of our results as reported under GAAP. Additionally, because non-GAAP financial measures may be defined differently by other
companies in our industry, our definitions may not be comparable to similarly titled measures of other companies, thereby
diminishing their utility. For a reconciliation of Adjusted EBITDA and DCF to their most directly comparable measures calculated
and presented in accordance with GAAP, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results
of Operations - Results of Operations. For a reconciliation of Adjusted FCF and Adjusted FCF after distributions to their most
directly comparable measure calculated and presented in accordance with GAAP, see Item 7. Management’s Discussion and
Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources.
COMPARABILITY OF OUR FINANCIAL RESULTS
During the normal course of business, we amend or modify our contractual agreements with customers. These amendments or
modifications require the agreements to be reassessed under ASU No. 2016-02, Leases (“ASC 842”), which can impact the
classification of revenues or costs associated with the agreement. These reassessments may impact the comparability of our
financial results.

2022 Compared to 2021
Total revenues and other income increased $1,586 million in 2022 compared to 2021. This was primarily due to higher NGL
prices of $380 million and product volumes of $356 million within the G&P segment. The increase also includes a non-cash gain
on sales-type lease of $509 million as a result of a contract modification in the third quarter of 2022, as well as a $155 million
increase in income from equity method investments in 2022. Higher service revenue within our L&S segment of $139 million,
driven primarily by higher pipeline throughput and terminal blending services, also contributed to the increase in 2022.
Cost of revenues increased $185 million in 2022 compared to 2021. This was primarily due to higher expenses related to repairs
and maintenance, project spend, and energy costs. Higher environmental response and remediation costs associated with a
release of crude oil on our pipeline near Edwardsville, Illinois in early 2022 also contributed to the increase.
Purchased product costs increased $478 million in 2022 compared to 2021. This was primarily due to higher volumes of $255
million and higher prices of $315 million, primarily in the G&P segment, partially offset by a decrease of $92 million due to
changes in the fair value of an embedded derivative in a natural gas purchase commitment.
Rental cost of sales and rental cost of sales-related parties decreased $68 million in 2022 compared to 2021. This was primarily
due to modifications to lease contracts which resulted in costs now being recorded to purchases - related parties, as noted
below, as opposed to rental cost of sales - related parties. The decreases were partially offset by higher operating costs and
repairs and maintenance costs.
Purchases-related parties increased $194 million in 2022 compared to 2021. This was primarily due to modifications to lease
contracts which resulted in costs now being recorded to purchases - related parties as opposed to rental cost of sales - related
parties, as noted above. There were also increased transportation costs in 2022.
Depreciation and amortization expense decreased $57 million in 2022 compared to 2021. This was primarily due to accelerated
depreciation on idled assets recorded during 2021, and lower depreciation as a result of the derecognition of fixed assets
resulting from the modification of certain lease contracts resulting in sales-type lease accounting treatment.
Interest expense, net of amounts capitalized increased $58 million in 2022 compared to 2021. This was primarily due to
refinancing debt with fixed rate debt at higher interest rates in 2022. These increases were partially offset by lower variable rate
interest incurred in 2022. Refer to the Liquidity and Capital Resources section for further information.

SEGMENT REPORTING
We classify our business in the following reportable segments: L&S and G&P. We evaluate the performance of our segments
using Segment Adjusted EBITDA. Segment Adjusted EBITDA represents Adjusted EBITDA attributable to the reportable
segments. Amounts included in income from operations and excluded from Segment Adjusted EBITDA include: (i) depreciation
and amortization; (ii) income/(loss) from equity method investments; (iii) distributions and adjustments related to equity method
investments; (iv) gain on sales-type leases; (v) impairment expense; (vi) restructuring expenses (vii) noncontrolling interests; and
(viii) 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.
The tables below present information about Segment Adjusted EBITDA for the reported segments for the years ended
December 31, 2022, 2021 and 2020.

2022 Compared to 2021
Service revenue increased $139 million in 2022 compared to 2021. The increase was primarily due to an increase of $84 million,
from increased crude oil and refined product pipeline throughput outweighing lower average tariff rates. The lower average tariff
rate was a result of changes in the mix of throughputs on various pipeline systems, which more than offset tariff rate increases
effective in 2022. There were also increased revenue from terminal blending services and marine rate escalations of $54 million,
which was partially offset by terminals sold during the year. An increase of $4 million resulted from changes in the presentation of
revenue between service revenue, rental income and sales-type lease revenue driven by modifications to agreements with MPC.
Rental income increased $31 million in 2022 compared to 2021. This was primarily due to increased storage fees and fee
escalations. The increase was partially offset by $32 million from changes in the presentation of lease income between service
revenue, rental income and sales-type lease revenue as a result of modifications to lease contracts.
Sales-type lease revenue increased $30 million in 2022 compared to 2021. This was primarily due to an increase of $28 million
from changes in the presentation of lease income between service revenue, rental income and sales-type lease revenue driven
by modifications to agreements with MPC.
Income from equity method investments increased $114 million in 2022 compared to 2021. This was primarily due to increased
throughput on equity method investment pipeline systems, including the Whistler pipeline which was placed into service in the
third quarter of 2021.
Cost of revenues increased $15 million and Purchases - related parties increased $129 million in 2022 compared to 2021.
Modifications to lease contracts with MPC resulted in a greater portion of costs being recorded to purchases - related parties as
opposed to rental cost of sales - related parties, which is included in cost of revenues, causing a $79 million increase in
Purchases - related parties and a corresponding decrease to cost of revenues. The overall increase in the accounts was driven
by higher maintenance-related project expenses and higher energy and remediation costs as compared to 2021.
Depreciation and amortization decreased $31 million in 2022 compared to 2021. This was primarily due to the derecognition of
fixed assets due to the modification of certain lease contracts and accelerated depreciation on refining logistics assets at MPC’s
idled Gallup refinery.

2022 Compared to 2021
Service revenue increased $33 million in 2022 compared to 2021. This was primarily due to higher fees from higher volumes in
the Southwest and Marcellus of $42 million and an increase in revenue from cost reimbursements in the Marcellus of $13 million.
The increases were partially offset by a $30 million decrease in revenue related to lower cost reimbursements and volumes in
the Rockies.
Rental income decreased $60 million offset by an increase of $62 million in Sales-type lease revenue in 2022 compared to 2021.
These offsetting variances reflect the modification of a gathering and compression agreement in the third quarter of 2022 that
resulted in a change in the presentation of revenue between rental income and sales-type lease revenue.
Product related revenue increased $726 million in 2022 compared to 2021. This was primarily due to higher NGL prices in the
Southwest, Marcellus, Southern Appalachia, Rockies and Bakken of approximately $380 million and fees from higher volumes in
the Southwest, Rockies and Bakken of $356 million.
Income from equity method investments increased $41 million in 2022 compared to 2021 primarily due to higher volumes and
rates associated with joint ventures in the Utica, Marcellus and Southwest regions, partially offset by increased facility expenses
from a joint venture in the Southwest.
Other income increased $469 million in 2022 compared to 2021 primarily due to a non-cash gain on lease reclassification of
$509 million as a result of a contract modification in the third quarter of 2022. The gain was partially offset by a loss on disposal
of assets during 2022.
Cost of revenues increased $102 million in 2022 compared to 2021. This increase is attributable to higher operating costs, which
were primarily driven by higher energy costs, and repairs and maintenance costs in the Marcellus, Rockies, Southern Appalachia
and Southwest.
Purchased product costs increased $478 million in 2022 compared to 2021. This was primarily due to higher prices of $315
million in the Southwest and Southern Appalachia, and higher volumes in the Southwest and Rockies of $255 million, partially
offset by a decrease of $92 million due to changes in the fair value of an embedded derivative in a natural gas purchase
commitment.
Purchases - related parties increased $65 million in 2022 compared to 2021. This increase is attributable to higher volumes in
the Rockies, which drove higher related-party purchased-product costs and transportation costs.
Depreciation and amortization decreased $26 million in 2022 compared to 2021. This was primarily due to lower depreciation as
a result of the derecognition of fixed assets as a result of a lease reclassification in the third quarter of 2022.
Impairment expense decreased $42 million in 2022 compared to 2021 due to impairments recorded in the 2021 period related to
our continued emphasis on portfolio optimization with the closure of certain non-core assets.

Cash Flows Provided by Operating Activities - Net cash provided by operating activities increased $108 million, or two
percent, in 2022 compared to 2021, primarily due to increased throughput and distributions from our equity method investments.
Cash Flows Used in Investing Activities - Net cash used in investing activities increased $438 million in 2022 compared to
2021 due to higher capital spending, primarily within our G&P segment, in response to an increase in producer demand. Cash
used in investing activities also reflects an increase in contributions to equity method investments, which included the $60 million
contribution to our Bakken Pipeline joint venture to fund our share of a debt repayment by the joint venture, and $28 million for
the acquisition of assets in 2022.
Cash Flows Used in and Provided by Financing Activities - Financing activities were a $3,838 million use of cash in 2022
compared to a $4,395 million use of cash in 2021. The decrease in the use of cash was primarily due to the Supplemental
Distribution Amount of $603 million that was distributed to unitholders during the fourth quarter of 2021. In addition, unit
repurchases were $139 million lower in 2022 compared to 2021. These decreases were partially offset with higher net debt
repayments of $273 million in 2022 compared to net debt repayments of $196 million in 2021 and higher base distributions of
$77 million in 2022 as a result of a 10 percent increase to the quarterly distribution effective for the third quarter of 2022.
Adjusted Free Cash Flow - For the year ended December 31, 2022, we generated adjusted free cash flow of $4.1 billion after
net cash used in investing activities of $1.0 billion. This provided us the flexibility to return capital to our unitholders through the
repurchase $491 million of public common units during 2022 and increase our distribution by 10% effective for the third quarter of
2022. The table below provides a reconciliation of Adjusted FCF and Adjusted FCF after distributions from net cash provided by
operating activities for the years ended December 31, 2022, 2021 and 2020.

Debt and Liquidity Overview
Senior Notes
On March 14, 2022, MPLX issued $1.5 billion aggregate principal amount of 4.950 percent senior notes in a public offering due
March 2052 (the “2052 Senior Notes”). The 2052 Senior Notes were offered at a price to the public of 98.982 percent of par with
interest payable semi-annually in arrears, commencing on September 14, 2022. The net proceeds were used to repay amounts
outstanding under the MPC Loan Agreement and the MPLX Credit Agreement as well as for general partnership purposes.
59
On August 11, 2022, MPLX issued $1.0 billion aggregate principal amount of 4.950 percent senior notes due September 2032
(the “2032 Senior Notes”) in an underwritten public offering. The 2032 Senior Notes were offered at a price to the public of
99.433 percent of par with interest payable semi-annually in arrears, commencing on March 1, 2023. The net proceeds were
used to redeem all of the 3.50 percent senior notes due December 2022 and all of the 3.375 percent senior notes due March
2023, as discussed below.
On August 25, 2022, MPLX redeemed all of the $500 million 3.50 percent senior notes due December 2022, $14 million of which
was issued by Andeavor Logistics LP, at 100.101 percent of the aggregate principal amount, plus accrued and unpaid interest to,
but not including the redemption date. On September 15, 2022, MPLX redeemed all of the $500 million 3.375 percent senior
notes due March 2023 at 100 percent of the aggregate principal amount. The impact of these debt extinguishments was not
material to the Consolidated Statements of Income.
As of December 31, 2022, we had $20.1 billion in aggregate principal amount of senior notes outstanding. The increase
compared to year-end 2021 resulted from the issuance of the 2052 Senior Notes as discussed above.
On February 9, 2023, MPLX issued $1.6 billion aggregate principal amount of notes, consisting of $1.1 billion principal amount of
5.00 percent senior notes due 2033 (the “2033 Senior Notes”) and $500 million principal amount of 5.65 percent senior notes
due 2053 (the “2053 Senior Notes”). The 2033 Senior Notes were offered at a price to the public of 99.170 percent of par with
interest payable semi-annually in arrears, commencing on September 1, 2023. The 2053 Senior Notes were offered at a price to
the public of 99.536 percent of par with interest payable semi-annually in arrears, commencing on September 1, 2023. MPLX
used $600 million of the net proceeds to redeem all of the outstanding Series B preferred units. We also provided notice to
redeem all of MPLX’s and MarkWest’s $1.0 billion aggregate principal amount of 4.50 percent senior notes due July 2023.
Credit Agreement
On July 7, 2022, MPLX entered into a new five-year credit agreement (the “MPLX Credit Agreement”) to replace the previous
$3.5 billion credit facility that was scheduled to expire in July 2024. The new MPLX Credit Agreement matures in July 2027 and,
among other things, provides for a $2 billion unsecured revolving credit facility and letter of credit issuing capacity under the
facility of up to $150 million. Letter of credit issuing capacity is included in, not in addition to, the $2 billion borrowing capacity.
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.
The borrowing capacity under the MPLX Credit Agreement may be increased by up to an additional $1 billion, subject to certain
conditions, including the consent of 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. We are charged various fees and expenses in connection with the agreement, including administrative agent fees,
commitment fees on the unused portion of the bank revolving credit facility and fees with respect to issued and outstanding
letters of credit. The applicable margins to the benchmark interest rates and certain fees fluctuate based on the credit ratings in
effect from time to time on MPLX’s long-term debt.
The MPLX Credit Agreement contains certain representations and warranties, affirmative and negative covenants and events of
default that we consider usual and customary for an agreement of that type that could, among other things, limit our ability to pay
distributions to our unitholders. The financial covenant requires us 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, including for certain acquisitions completed and capital projects undertaken during the relevant period.
Other covenants restrict us and/or certain of our subsidiaries from incurring debt, creating liens on our assets and entering into
transactions with affiliates. As of December 31, 2022, we were in compliance with this financial covenant with a ratio of
Consolidated Total Debt to Consolidated EBITDA of 3.5 to 1.0, as well as all other covenants contained in the MPLX Credit
Agreement.
60
MPC Loan Agreement
MPLX is party to a loan agreement with MPC (the “MPC Loan Agreement”). Under the terms of the MPC Loan Agreement, MPC
extends loans to MPLX on a revolving basis as requested by MPLX and as agreed to by MPC. The borrowing capacity of the
MPC Loan Agreement is $1.5 billion aggregate principal amount of all loans outstanding at any one time. The MPC Loan
Agreement is scheduled to expire, and borrowings under the MPC Loan Agreement are scheduled to mature and become due
and payable on July 31, 2024, provided that MPC may demand payment of all or any portion of the outstanding principal amount
of the loan, together with all accrued and unpaid interest and other amounts (if any), at any time prior to the maturity date. During
2022, borrowings under the MPC Loan Agreement bore interest at the one-month LIBOR plus 1.25 percent or such lower rate as
would be applicable to such loans under the MPLX Credit Agreement. The MPC Loan Agreement was amended effective
January 1, 2023 to update the interest rate to one-month term SOFR adjusted upward by 0.10 percent plus 1.25 percent or such
lower rate as would be applicable to such loans under the MPLX Credit Agreement as discussed in Item 8. Financial Statements
and Supplementary Data - Note 17. All other terms of the MPC Loan Agreement remain unchanged.

(1) There was less than $1 million in letters of credit outstanding on the MPLX Credit Agreement.
For further discussion, see Item 8. Financial Statements and Supplementary Data – Note 6 and Note 17.
Our intention is to maintain an investment grade credit profile. As of February 1, 2023, the credit ratings on our senior unsecured
debt were at or above investment grade level as follows:
Rating Agency
Rating
Moody’s
Fitch
Standard & Poor’s
Baa2 (stable outlook)
BBB (stable outlook)
BBB (stable outlook)
The ratings shown above 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.
The agreements governing our debt obligations do 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 in the credit
ratings of our senior unsecured debt ratings could, among other things, increase the applicable interest rates and other fees
payable under the MPLX Credit Agreement, which may limit our flexibility to obtain future financing.
Our liquidity totaled $3.7 billion at December 31, 2022, consisting of:

We expect our ongoing sources of liquidity to include cash generated from operations, borrowings under our revolving credit
facilities and access to capital markets. We believe that cash generated from these sources will be sufficient to meet our short-
term and long-term funding requirements, including working capital requirements, capital expenditure requirements, contractual
obligations and quarterly cash distributions. Our material future obligations include interest on debt, payments of debt principal,
purchase obligations including contracts to acquire PP&E and our operating leases and service agreements. We may also, from
61
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 and execute unit
repurchases under our unit repurchase program.
MPC manages our cash and cash equivalents on our behalf directly with third-party institutions as part of the treasury services
that it provides to us. From time to time, we may also utilize other sources of liquidity, including the formation of joint ventures or
sales of non-strategic assets.
Equity and Preferred Units Overview
Preferred Units
Series A Preferred Units - On May 13, 2016, MPLX completed the private placement of approximately 30.8 million Series A
preferred units for a cash purchase price of $32.50 per unit. The aggregate net proceeds of approximately $984 million from the
sale of the preferred units were used for capital expenditures, repayment of debt and general business purposes.
The Series A preferred units rank senior to all common units with respect to distributions and rights upon liquidation. The holders
of the Series A preferred units received cumulative quarterly distributions equal to $0.528125 per unit for each quarter prior to the
second quarter of 2018. Beginning with the second quarter of 2018, the holders of the Series A preferred units are entitled to
receive a quarterly distribution equal to the greater of $0.528125 per unit or the amount of distributions they would have received
on an as converted basis. Distributions paid to Series A preferred unitholders during the years ended December 31, 2022, 2021
and 2020 were $85 million, $100 million and $81 million, respectively. The distribution for the year ended December 31, 2021
includes a Supplemental Distribution Amount of $18 million, or $0.5750 per unit.
In December 2021, certain holders exercised their right to convert a total of 0.1 million Series A preferred units into common
units. Approximately 29.5 million Series A preferred units remain outstanding as of December 31, 2022.
Series B Preferred Units - As of December 31, 2022, MPLX had 600,000 units of 6.875 percent Fixed-to-Floating Rate
Cumulative Redeemable Perpetual Preferred Units representing limited partner interests of ANDX at a price to the public of
$1,000 per unit. The Series B preferred units are pari passu with the Series A preferred units with respect to distribution rights
and rights upon liquidation.
Distributions on the Series B preferred units are payable semi-annually through February 15, 2023. Distributions paid to Series B
preferred unitholders during each of the years ended December 31, 2022, 2021 and 2020 were $41 million.
On February 15, 2023, MPLX exercised its right to redeem all of the Series B preferred units outstanding. MPLX paid unitholders
the Series B preferred unit redemption price of $1,000 per unit.
Unit Repurchase Program
On November 2, 2020, MPLX announced the board authorization of a unit repurchase program for the repurchase of up to $1
billion of MPLX’s outstanding common units held by the public, which was exhausted during the fourth quarter of 2022. On
August 2, 2022, we announced the board authorization for the repurchase of up to an additional $1 billion of MPLX common
units held by the public. This repurchase authorization has no expiration date. MPLX may utilize various methods to effect the
repurchases, which could include open market repurchases, negotiated block transactions, tender offers, accelerated unit
repurchases or open market solicitations for units, some of which may be effected through Rule 10b5-1 plans. The timing and
amount of repurchases depends upon several factors, including market and business conditions, and repurchases may be
suspended, discontinued, or restarted at any time. The following table summarizes activity executed on the unit repurchase
program during the years ended December 31, 2022, 2021 and 2020:

(1) Cash paid for common units repurchased and average cost per unit includes commissions paid to brokers during the period.
As of December 31 2022, we had $846 million available under our remaining unit repurchase authorization.
Distributions
We intend to pay a minimum quarterly distribution of $0.2625 per unit, which equates to $263 million per quarter, or $1,051
million per year, based on the number of common units outstanding. On January 25, 2023, we announced that the board of
directors of our general partner had declared a distribution of $0.7750 per common unit, which was paid on February 14, 2023 to
common unitholders of record on February 6, 2023. This represents a 10 percent increase over the fourth quarter 2021
62
distribution. Although our Partnership Agreement requires that we distribute all of our available cash each quarter, we do not
otherwise have a legal obligation to distribute any particular amount per common unit.
The allocation of total quarterly cash distributions to limited and preferred partners is as follows for the years ended
December 31, 2022, 2021 and 2020. Our distributions are declared subsequent to quarter end; therefore, the following table

Capital Expenditures
Our operations are capital intensive, requiring investments to expand, upgrade, enhance or maintain existing operations and to
meet environmental and operational regulations. Our capital requirements consist of growth capital expenditures and
maintenance capital expenditures. Growth capital expenditures are those incurred for acquisitions or capital improvements that
we expect will increase our operating capacity for volumes gathered, processed, transported or fractionated, decrease operating
expenses within our facilities or increase operating income over the long term. Examples of growth capital expenditures include
costs to develop or acquire additional pipeline, terminal, processing or storage capacity. In general, growth capital includes costs
that are expected to generate additional or new cash flow for MPLX. In contrast, maintenance capital expenditures are those
made to replace partially or fully depreciated assets, to maintain the existing operating capacity of our assets and to extend their
useful lives, or other capital expenditures that are incurred in maintaining existing system volumes and related cash flows.
Our capital expenditures for the past three years are shown in the table below:

(2) Total growth capital expenditures exclude $28 million of acquisitions in 2022.
(3) Investments in unconsolidated affiliates, return of capital, acquisitions, and additions to property, plant and equipment are shown as

(4) Growth capital reimbursements are included in changes in deferred revenue within the operating activities section of the Consolidated
Statements of Cash Flows. Maintenance capital reimbursements are included in the Contributions from MPC line within financing activities
section of the Consolidated Statements of Cash Flows.
For 2023, we announced a capital outlook of $950 million, net of reimbursements, which includes growth capital of $800 million
and maintenance capital of $150 million. Our 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 our capital plan is mostly focused on other
investments targeted at the expansion or debottlenecking of existing assets to meet customer demand. We continuously
evaluate our capital plan and make changes as conditions warrant.
64
Cash Commitments
Our material cash requirements include the following contractual obligations and other cash commitments as of December 31,
2022.
Our contractual obligations primarily consist of outstanding borrowings on debt, commitment and administrative fees and interest.
Additional information for third-party debt is included in Item 8. Financial Statements and Supplementary Data – Note 17. See
Item 8. Financial Statements and Supplementary Data – Note 6 for additional information for the related party loan. Our cash
commitment at December 31, 2022 was $32,464 million.
Our contractual commitment for co-location services agreements was $4,004 million at December 31, 2022. These agreements
obligate us to pay MPC for operational and other services provided to the subsidiaries of MPLX Refining Logistics LLC.
Finance and operating leases relate primarily to facilities and equipment under lease, including ground leases, building space,
office and field equipment, storage facilities and transportation equipment. See Item 8. Financial Statements and Supplementary
Data – Note 20 for further discussion about our lease obligations. Our cash commitment at December 31, 2022 was $977 million.
Transportation and terminalling agreements that obligate us to minimum volume, throughput or payment commitments over the
remaining terms of the agreements, have terms that range from less than one year to nine years. We expect to pass any
minimum payment commitments through to producer customers. Minimum fees due under transportation agreements do not
include potential fee increases as required by FERC. See Item 8. Financial Statements and Supplementary Data – Note 21 for
further discussion. Our cash commitment at December 31, 2022 was $878 million.
We have commitments under contracts to acquire property, plant and equipment, for which additional information is included in
Item 8. Financial Statements and Supplementary Data – Note 21. Our cash commitment at December 31, 2022 was $165
million. These commitments were primarily related to G&P plant expansions.
Natural gas purchase obligations consist primarily of a purchase agreement with a producer in our Southern Appalachia
Operations. The contract provides for the purchase of keep-whole volumes at a specific price and is a component of a broader
regional arrangement. The contract price is designed to share a portion of the frac spread with the producer and as a result, the
amounts reflected for the obligation exceed the cost of purchasing the keep-whole volumes at a market price. The contract is
considered an embedded derivative (see Item 8. Financial Statements and Supplementary Data – Note 16 for the fair value of
the frac spread sharing component). We use the estimated future frac spreads as of December 31, 2022 for calculating this
obligation. The counterparty to the contract has the option to renew the gas purchase agreement and the related keep-whole
processing agreement after 2027. Our cash commitment, not including this renewal option, at December 31, 2022 was $40
million.
Our other cash commitments consist of expense projects, right of way and easement obligations and ARO commitments. These
other cash commitments at December 31, 2022 totaled $224 million.
In addition, we have omnibus agreements and employee agreements with MPC. One of the omnibus agreements with MPC
addresses our payment of a fixed annual fee to MPC for the provision of executive management services by certain executive
officers of our general partner and our reimbursement to MPC for the provision of certain general and administrative services to
us.
We also pay MPC additional amounts based on the costs actually incurred by MPC in providing other services, except for the
portion of the amount attributable to engineering services, which is based on the amounts actually incurred by MPC and its
affiliates plus an incremental surcharge. In addition, we are obligated to reimburse MPC for most out-of-pocket costs and
expenses incurred by MPC on our behalf.
MPLX has various employee agreements with MPC under which MPLX reimburses MPC for employee benefit expenses, along
with the provision of operational and management services in support of both our L&S and G&P segments’ operations.
We incurred $1,723 million of costs under various agreements with MPC, including the omnibus, co-location and employee
agreements for 2022.
Effects of Inflation
Inflation did not have a material impact on our results of operations for the years ended December 31, 2022, 2021 or 2020. We
have observed higher costs for labor and materials used in our business during the year ended December 31, 2022. To the
extent permitted by competition, regulation and our existing agreements, we have and expect to continue to pass along a portion
of increased costs to our customers in the form of higher fees.
65
TRANSACTIONS WITH RELATED PARTIES
As of December 31, 2022, MPC owned our general partner and an approximate 65 percent limited partner interest in us. We
perform a variety of services for MPC related to the transportation of crude and refined products, including renewable diesel, via
pipeline, truck or marine as well as terminal services, storage services and fuels distribution and marketing services, among
others. The services that we provide may be based on regulated tariff rates or on contracted rates. In addition, MPC performs
certain services for us related to information technology, engineering, legal, accounting, treasury, human resources and other
administrative services. For further discussion of agreements and activity with MPC and related parties see Item 1. Business and
Item 8. Financial Statements and Supplementary Data – Note 6.
Excluding significant non-cash items, including losses for impairment of equity method investments and gains on lease
reclassifications, MPC accounted for 47 percent, 50 percent and 55 percent of our total revenues and other income for the years
ended December 31, 2022, 2021 and 2020, respectively. Of our total costs and expenses, excluding impairment expense, MPC
accounted for 25 percent, 26 percent and 30 percent for the years ended December 31, 2022, 2021 and 2020, respectively.
ENVIRONMENTAL MATTERS AND COMPLIANCE COSTS
We are subject to extensive federal, state and local environmental laws and regulations. These laws, which change frequently,
regulate the discharge of materials into the environment or otherwise relate to protection of the environment. Compliance with
these laws and regulations may require us to remediate environmental damage from any discharge of hazardous, petroleum or
chemical substances from our facilities or require us to install additional pollution control equipment on our equipment and
facilities. Our failure to comply with these or any other environmental or safety-related regulations could result in the assessment
of administrative, civil or criminal penalties, the imposition of investigatory and remedial liabilities, and the issuance of injunctions
that may subject us to additional operational constraints.
Future expenditures may be required to comply with the CAA and other federal, state and local requirements for our various
facilities. The impact of these legislative and regulatory developments, if enacted or adopted, could result in increased
compliance costs and additional operating restrictions on our business, each of which could have an adverse impact on our
financial position, results of operations and liquidity. MPC will indemnify us for certain of these costs.
Legislation and regulations pertaining to 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.
We have incurred and may continue to incur substantial capital, operating and maintenance, and remediation expenditures as a
result of these environmental laws and regulations. If these expenditures, as with all costs, are not ultimately reflected in the fees
and tariff rates we receive for our 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, but not limited to, the age and location of its operating facilities. Our
environmental expenditures for each of the past three years were:

(1) Based on the American Petroleum Institute’s definition of environmental expenditures.
(2) These amounts include spending charged against remediation reserves and exclude non-cash accruals for environmental remediation.
Environmental remediation costs increased in 2022 compared to 2021 due to a release of crude oil on our 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. We
believe we comply with all legal requirements regarding the environment, but since not all of them are fixed or presently
determinable (even under existing legislation) and may be affected by future legislation or regulations, 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.
66
Our environmental capital expenditures are expected to approximate $18 million 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, 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 (i) 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
(ii) 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.
The policies and estimates discussed below are considered by management to be critical to an understanding of our financial
statements because their application requires the most significant judgments from management in estimating matters for
financial reporting that are inherently uncertain. See Item 8. Financial Statements and Supplementary Data – Note 2 for
additional information on these policies and estimates, as well as a discussion of additional accounting policies and estimates.
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
do 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. We use a cost method approach for non-recurring fair value measurements related to the
valuation of our leased assets. See Item 8. Financial Statements and Supplementary Data - Note 15 for disclosures regarding
our fair value measurements.
Significant uses of fair value measurements include:
•
•
•
assessment of impairment of long-lived assets, intangible assets, goodwill and equity method investments;
assessment of values for assets in implicit leases, including sales-type leases;
assessment of values for underlying assets to record net investment in sales-type leases;
67
•
•
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
assumptions. Significant assumptions include:
•
•
•
•
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 as well as commodity prices. Such estimates are
consistent with those used in our planning and capital investment reviews.
Future volumes. Our estimates of future throughput of crude oil, natural gas, NGL and refined product volumes are
based on internal forecasts and depend, in part, on assumptions about our customers’ drilling activity which is inherently
subjective and contingent upon a number of variable factors (including future or expected pricing considerations), many
of which are difficult to forecast. Management considers these volume forecasts and other factors when developing our
forecasted cash flows.
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
commodities, a poor outlook for profitability, a significant reduction in pipeline throughput volumes, a significant reduction in
natural gas or NGL volumes processed, other changes to contracts or changes in the regulatory environment in which the asset
or equity method investment is located.
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 is at least at the segment level and in some cases for similar assets in the same geographic region
where cash flows can be separately identified. If the sum of the undiscounted cash flows is less than the carrying value of an
asset group, fair value is calculated, and the carrying value is written down if greater than the calculated fair value.
Goodwill Impairment Assessments
Unlike long-lived assets, goodwill must be tested for impairment at least annually, and between annual tests if an event occurs or
circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount.
Goodwill is tested for impairment at the reporting unit level. We have five reporting units, three of which have goodwill allocated
to them. 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, MPLX had three reporting units with goodwill totaling approximately $7.6 billion, which includes goodwill
associated with our Crude Gathering reporting unit of $1.1 billion. For the annual impairment assessment as of November 30,
2022, management performed only a qualitative assessment for two reporting units as we determined it was more likely than not
that the fair values of the reporting units exceeded their carrying values. The fair value of the Crude Gathering reporting unit for
which a quantitative assessment was performed was determined based on applying both a discounted cash flow, or income
approach, as well as a market approach which resulted in the fair value of the reporting unit exceeding its carrying value by
greater than 10 percent. The significant assumptions that were used to develop the estimate of the 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. A 100-basis point increase to the discount rate used to estimate the fair value of the reporting unit would not have
resulted in a goodwill impairment charge as of November 30, 2022.
68
Significant assumptions used to estimate the reporting unit fair value included estimates of future cash flows and market
information for comparable businesses. 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. See Item 8. Financial Statements and
Supplementary Data - Note 14 for additional information relating to our reporting units and goodwill.
Equity Method Investment Impairment Assessments
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 $4.1 billion of equity method investments recorded on the Consolidated Balance Sheets.
An estimate of the sensitivity to net income resulting from impairment calculations is not practicable, given the numerous
assumptions (e.g., pricing, volumes and discount rates) that can materially affect our estimates. That is, unfavorable adjustments
to some of the above listed adjustments may be offset by favorable adjustments in other assumptions.
See Item 8. Financial Statements and Supplementary Data - Note 5 for additional information on our equity method investments
and Note 14 for additional information on our goodwill and intangibles.
Leases
In accounting for leases, we analyze new or modified leases for lease classification. One of the key inputs into the lease
classification analysis is the fair value of the leased assets. For newly classified sales-type leases, the net investment in the
lease is recorded at the estimated fair value of the underlying leased assets. Significant assumptions used to estimate the leased
assets’ fair value include market information for comparable assets and cost estimates to replace the service capacity of an
asset.
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 (i) the power to direct the activities of the VIE
that most significantly impact the VIE’s economic performance and (ii) 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.
VIEs are discussed in Item 8. Financial Statements and Supplementary Data - Note 5.
Contingent Liabilities
We accrue contingent liabilities for legal actions, claims, litigation, environmental remediation, tax deficiencies related to
operating taxes and third-party indemnities for specified tax matters when such contingencies are both probable and estimable.
We regularly assess these estimates in consultation with legal counsel to consider resolved and new matters, material
developments in court proceedings or settlement discussions, new information obtained as a result of ongoing discovery and
past experience in defending and settling similar matters. Actual costs can differ from estimates for many reasons. For instance,
settlement costs for claims and litigation can vary from estimates based on differing interpretations of laws, opinions on degree of
responsibility and assessments of the amount of damages. Similarly, liabilities for environmental remediation may vary from
69
estimates because of changes in laws, regulations and their interpretation, additional information on the extent and nature of site
contamination and improvements in technology.
We generally record losses related to these types of contingencies as cost of revenues or selling, general and administrative
expenses on the Consolidated Statements of Income, except for tax deficiencies unrelated to income taxes, which are recorded
as other taxes.
An estimate of the sensitivity to net income if other assumptions had been used in recording these liabilities is not practical
because of the number of contingencies that must be assessed, the number of underlying assumptions and the wide range of
reasonably possible outcomes, in terms of both the probability of loss and the estimates of such loss.
For additional information on contingent liabilities, see Item 7. Management’s Discussion and Analysis of Financial Condition and
Results of Operations - Environmental Matters and Compliance Costs and Item 8. Financial Statements and Supplementary
Data - Note 21.
Item 7A. Quantitative and Qualitative Disclosures about Market Risk
We are exposed to market risks related to the volatility of commodity prices. We employ various strategies, including the potential
use of commodity derivative instruments, to economically hedge the risks related to these price fluctuations. We are also
exposed to market risks related to changes in interest rates. As of December 31, 2022, we did not have any open financial or
commodity derivative instruments to hedge the economic risks related to interest rate fluctuations or the volatility of commodity
prices, respectively; however, we continually monitor the market and our exposure and may enter into these arrangements in the
future.
Commodity Price Risk
We 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 our 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 our producer customers, such prices also indirectly affect profitability. We may enter into
derivative contracts, which are primarily swaps traded on the Over-the-Counter market as well as fixed price forward contracts.
Our risk management policy does not allow us to enter into speculative positions with our derivative contracts. Execution of our
hedge strategy and the continuous monitoring of commodity markets and our open derivative positions are carried out by our
hedge committee, comprised of members of senior management.
To mitigate our cash flow exposure to fluctuations in the price of NGLs, we may use NGL derivative swap contracts. A small
portion of our NGL price exposure may be managed by using crude oil contracts. To mitigate our cash flow exposure to
fluctuations in the price of natural gas, we may use natural gas derivative swap contracts, taking into account the partial offset of
our long and short natural gas positions resulting from normal operating activities.
We 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 we have derivative positions in
excess of the product delivered or expected to be delivered, the excess derivative positions may be terminated.
Management conducts a standard credit review on counterparties to derivative contracts, and we have provided the
counterparties with a guaranty as credit support for our obligations. We use standardized agreements that allow for offset of
certain positive and negative exposures in the event of default or other terminating events, including bankruptcy.
Outstanding Derivative Contracts
We have a natural gas purchase commitment embedded in a keep-whole processing agreement with a producer customer in the
Southern Appalachian region expiring in December 2027. The customer has the unilateral option to extend the agreement for
one five-year term through December 2032. For accounting purposes, the natural gas purchase commitment and the term
extending option has been aggregated into a single compound embedded derivative. The probability of the customer exercising
its option is determined based on assumptions about the customer’s potential business strategy decision points that may exist at
the time they would elect whether to renew the contract. The changes in fair value of this compound embedded derivative are
based on the difference between the contractual and index pricing, and the probability of the producer customer exercising its
option to extend. The changes in fair value are recorded in earnings through Purchased product costs on the Consolidated
Statements of Income. As of December 31, 2022 and 2021, the estimated fair value of this contract was a liability of $61 million
and $108 million, respectively.
70
Open Derivative Positions and Sensitivity Analysis
The estimated fair value of our Level 2 and 3 financial instruments are sensitive to the assumptions used in our pricing models.
Sensitivity analysis of a ten percent difference in our estimated fair value of Level 2 and 3 commodity derivatives (excluding
embedded derivatives) as of December 31, 2022 would not have affected income before income taxes for the year ended
December 31, 2022, given we had no open commodity derivative contracts during the year. 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.
Interest Rate Risk
Sensitivity analysis of the effect of a hypothetical 100-basis-point change in interest rates on third-party outstanding debt,
excluding finance leases, is provided in the following table. Fair value of cash and cash equivalents, receivables, accounts
payable and accrued interest approximate carrying value and are relatively insensitive to changes in interest rates due to the
short-term maturity of the instruments. Accordingly, these instruments are excluded from the table.

(1) Fair value was based on market prices, where available, or current borrowing rates for financings with similar terms and maturities.
(2) Assumes a 100-basis-point decrease in the weighted average yield-to-maturity at December 31, 2022.

balance of all outstanding variable-rate debt for the year ended December 31, 2022.
(4) MPLX had no outstanding borrowings on the MPLX Credit Agreement as of December 31, 2022.
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.
Credit Risk
We are subject to risk of loss resulting from non-payment by our customers to whom we provide services, lease assets, or sell
natural gas or NGLs. We believe that certain contracts where we sell NGLs and act as our producer customers’ agent would
allow us to pass those losses through to our customers, thus reducing our risk. Our credit exposure related to these customers is
represented by the value of our trade receivables or lease receivables. Where exposed to credit risk, we analyze the customer’s
financial condition prior to entering into a transaction or agreement, establish credit terms and monitor the appropriateness of
these terms on an ongoing basis. In the event of a customer default, we may sustain a loss and our cash receipts could be
negatively impacted.

Management’s Responsibilities for Financial Statements
The accompanying consolidated financial statements of MPLX LP and its subsidiaries (the “Partnership”) are the responsibility of
management of the Partnership’s general partner, MPLX GP LLC, 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.
MPLX GP LLC seeks to assure the objectivity and integrity of the Partnership’s 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 MPLX GP LLC 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
MPLX LP’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, MPLX LP’s management concluded that its internal control over financial reporting was effective as
of December 31, 2022.
The effectiveness of MPLX LP’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 Partners of MPLX LP and the Board of Directors of MPLX GP LLC
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of MPLX LP 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
Series A preferred units 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
74
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 14 to the consolidated financial statements, the Company’s consolidated goodwill balance was $7,645
million as of December 31, 2022. Additionally, as disclosed by management, the goodwill balance at December 31, 2022
includes goodwill associated with the 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 each reporting unit is determined
based on applying both a discounted cash flow method, or income approach, as well as a market approach. 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 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 is a critical audit matter are the significant judgment by management when determining the fair
value of the reporting unit, which led to a 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, testing management’s process for determining the fair value of the
reporting unit; evaluating the appropriateness of the income and market approaches used; testing the completeness and
accuracy of underlying data used by management in the approaches; and 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
MPLX LP is a diversified, large-cap master limited partnership formed by Marathon Petroleum Corporation that owns and
operates midstream energy infrastructure and logistics assets, and provides fuels distribution services. References in this report
to “MPLX LP,” “MPLX,” “the Partnership,” “we,” “ours,” “us,” or like terms refer to MPLX LP and its subsidiaries. References to our
sponsor and customer, “MPC,” refer collectively to Marathon Petroleum Corporation and its subsidiaries, other than the
Partnership. We are engaged in the gathering, transportation, storage and distribution of crude oil, refined products, other
hydrocarbon-based products and renewables; the gathering, processing and transportation of natural gas; and the
transportation, fractionation, storage and marketing of NGLs. MPLX’s principal executive office is located in Findlay, Ohio. MPLX
was formed on March 27, 2012 as a Delaware limited partnership and completed its initial public offering on October 31, 2012.
MPLX’s business consists of two segments based on the nature of services it offers: Logistics and Storage (“L&S”), which relates
primarily to crude oil, refined products, other hydrocarbon-based products and renewables; and Gathering and Processing
(“G&P”), which relates primarily to natural gas and NGLs. See Note 10 for additional information regarding the operations and
results of these segments.
On July 31, 2020, MPLX completed the exchange of Western Refining Wholesale, LLC (WRW”) to Western Refining Southwest,
Inc. (now known as Western Refining Southwest LLC) (“WRSW”), a wholly owned subsidiary of MPC, in exchange for the
redemption of 18,582,088 MPLX common units held by WRSW (the “Wholesale Exchange”). See Note 4 for additional
information regarding the Wholesale Exchange. These financial statements include the results of WRSW through July 31, 2020.
Basis of Presentation
The accompanying consolidated financial statements of MPLX have been prepared in accordance with GAAP. The consolidated
financial statements include all majority-owned and controlled subsidiaries. For non-wholly-owned consolidated subsidiaries, the
interests owned by third parties have been recorded as Noncontrolling interests on the accompanying Consolidated Balance
Sheets. Intercompany accounts and transactions have been eliminated. MPLX’s investments in which MPLX exercises
significant influence but does not control and does not have a controlling financial interest are accounted for using the equity
method. MPLX’s investments in VIEs, in which MPLX exercises significant influence but does not control and is not the primary
beneficiary, are also accounted for using the equity method.
Certain prior period financial statement amounts have been reclassified to conform to current period presentation.
2. Summary of Principal Accounting Policies
Use of Estimates
The preparation of financial statements in accordance with GAAP 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 materially from those estimates. Estimates are subject to uncertainties due to the levels of
subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change and
affect items such as valuing identified intangible assets; determining the fair value of derivative instruments; evaluating
impairments of long-lived assets, goodwill and equity investments; establishing estimated useful lives for long-lived assets;
acquisition accounting; estimating revenues, expense accruals and capital expenditures; valuing AROs; recognizing share-based
compensation expense; and determining liabilities, if any, for environmental and legal contingencies.
Revenue Recognition
Revenue is measured based on consideration specified in a contract with a customer. MPLX recognizes revenue when it
satisfies a performance obligation by transferring control over a product or providing services to a customer.
MPLX enters into a variety of contract types in order to generate Product sales and Service revenue. MPLX provides services
under the following types of arrangements:
•
Fee-based arrangements – Under fee-based arrangements, MPLX receives fees for the following services: gathering,
processing and transportation of natural gas; transportation, fractionation, exchange and storage of NGLs; and
transportation, terminalling, storage and distribution of crude oil, refined products, other hydrocarbon-based products,
and renewables. The revenue MPLX earns from these arrangements is generally directly related to the volume of
natural gas, NGLs, refined products or crude oil that is handled by or flows through MPLX’s systems and facilities and is
not normally directly dependent on commodity prices. In certain cases, MPLX’s arrangements provide for minimum
81
•
•
•
volume commitments. Fee-based arrangements are reported as Service revenue on the Consolidated Statements of
Income. Revenue is recognized over time as services are performed. In certain instances when specifically stated in the
contract terms, MPLX purchases product after fee-based services have been provided. Revenue from the sale of
products purchased after services are provided is reported as Product sales on the Consolidated Statements of Income
and recognized on a gross basis, as MPLX takes control of the product and is the principal in the transaction.
Percent-of-proceeds arrangements – Under percent-of-proceeds arrangements, MPLX gathers and processes natural
gas on behalf of producers; sells the resulting residue gas, condensate and NGLs at market prices; and remits to
producers an agreed-upon percentage of the proceeds. In other cases, instead of remitting cash payments to the
producer, MPLX delivers an agreed-upon percentage of the residue gas and NGLs to the producer (take-in-kind
arrangements) and sells the volumes MPLX retains to third parties or related parties. Revenue is recognized on a net
basis when MPLX acts as an agent and does not have control of the gross amount of gas and/or NGLs prior to it being
sold. Percent-of-proceeds revenue is reported as Service revenue - product related on the Consolidated Statements of
Income.
Keep-whole arrangements – Under keep-whole arrangements, MPLX gathers natural gas from the producer, processes
the natural gas and sells the resulting condensate and NGLs to third parties at market prices. Because the extraction of
the condensate and NGLs from the natural gas during processing reduces the Btu content of the natural gas, MPLX
must either purchase natural gas at market prices for return to producers or make cash payment to the producers equal
to the value of the energy content of this natural gas. Certain keep-whole arrangements also have provisions that
require MPLX to share a percentage of the keep-whole profits with the producers based on the oil to gas ratio or the
NGL to gas ratio. Service revenue - product related is recorded based on the value of the NGLs received on the date
the services are performed. Natural gas purchased to return to the producer and shared NGL profits are recorded as a
reduction of Service revenue - product related on the Consolidated Statements of Income on the date the services are
performed. Sales of NGLs under these arrangements are reported as Product sales on the Consolidated Statements of
Income and are reported on a gross basis as MPLX is the principal in the arrangement and controls the product prior to
sale. The sale of the NGLs may occur shortly after services are performed at the tailgate of the plant, or after a period of
time as determined by MPLX.
Purchase arrangements – Under purchase arrangements, MPLX purchases natural gas at either the wellhead or the
tailgate of a plant. MPLX then gathers and delivers the natural gas to pipelines where MPLX may resell the natural gas.
Wellhead purchase arrangements represent an arrangement with a supplier and are recorded in Purchased product
costs. Often, MPLX earns fees for services performed prior to taking control of the product in these arrangements and
Service revenue is recorded for these fees. Revenue generated from the sale of product obtained in tailgate purchase
arrangements is reported as Product sales on the Consolidated Statements of Income and is recognized on a gross
basis as MPLX purchases and takes control of the product prior to sale and is the principal in the transaction.
In many cases, MPLX provides services under contracts that contain a combination of more than one of the arrangements
described above. When fees are charged (in addition to product received) under percent-of-proceeds arrangements, keep-whole
arrangements or purchase arrangements, MPLX records such fees as Service revenue on the Consolidated Statements of
Income. The terms of MPLX’s contracts vary based on gas quality conditions, the competitive environment when the contracts
are signed, and customer requirements. Performance obligations are determined based on the specific terms of the
arrangements, economics of the geographical regions, and the services offered and whether they are deemed distinct. MPLX
allocates the consideration earned between the performance obligations based on the stand-alone selling price when multiple
performance obligations are identified.
Revenue from MPLX’s service arrangements will generally be recognized over time as the performance obligation is satisfied as
services are provided. MPLX has elected to use the output measure of progress to recognize revenue based on the units
delivered, processed or transported. The transaction price may have 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 each period. In instances in which
tiered pricing structures do not reflect our efforts to perform, MPLX will estimate variable consideration at contract inception.
Product sales will be recognized at a point in time when control of the product transfers to the customer.
Minimum volume commitments may create contract liabilities if current period payments can be used for future services.
Breakage is estimated and recognized into service revenue in instances where it is probable the customer will not use the credit
in future periods.
Amounts billed to customers for shipping and handling, electricity, and other costs to perform services are included in the
transaction price as a component of Revenues and other income on the Consolidated Statements of Income. Shipping and
handling costs associated with product sales are included in Purchased product costs on the Consolidated Statements of
Income.
Customers usually pay monthly based on the products purchased or services performed that month. Taxes collected from
customers and remitted to the appropriate taxing authority are excluded from revenue.
82
Based on the terms of certain contracts, MPLX is considered to be the lessor under several implicit operating and sales-type
lease arrangements in accordance with GAAP. Revenue and costs related to the portion of the revenue earned under these
contracts considered to be implicit operating leases are recorded as Rental income and Rental cost of sales, respectively, on the
Consolidated Statements of Income. Revenue related to the portion of the revenue earned under these contracts considered to
be implicit sales-type lease arrangements is recorded as Sales-type lease revenue on the Consolidated Statements of Income,
while related costs are recorded to Cost of revenues or Purchases - related parties.
Revenue and Expense Accruals
MPLX routinely makes accruals based on estimates for both revenues and expenses due to the timing of compiling billing
information, receiving certain third-party information and reconciling MPLX’s records with those of third parties. The delayed
information from third parties includes, among other things, actual volumes purchased, transported or sold, adjustments to
inventory and invoices for purchases, actual natural gas and NGL deliveries, and other operating expenses. MPLX makes
accruals to reflect estimates for these items based on its internal records and information from third parties. Estimated accruals
are adjusted when actual information is received from third parties and MPLX’s internal records have been reconciled.
Other Taxes
Other taxes primarily include real estate taxes.
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.
Receivables
Receivables primarily consist of customer accounts receivable, which are recorded at the invoiced amount and generally do not
bear interest. Allowances for doubtful accounts are generally recorded when it becomes probable that the receivable will not be
collected and are recorded to bad debt expense. We review the allowance quarterly with past-due balances over 150 days and
other higher-risk amounts being reviewed individually for collectability. Balances that remain outstanding after reasonable
collection efforts have been unsuccessful are written off through a charge to the valuation allowance and a credit to accounts
receivable.
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 (“ROU”) assets and lease liabilities.
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 and equipment leases. The lease
component of the payment for the marine and equipment asset classes is determined using a relative standalone selling price.
Operating lease expense is recognized on a straight-line basis over the lease term. See Note 20 for additional disclosures about
our lease contracts.
As a lessor under ASC 842, MPLX may be required to re-classify existing operating leases to sales-type leases upon
modification and related reassessment of the leases. See Note 20 for further information regarding our ongoing evaluation of the
impacts of lease reassessments as modifications occur. The net investment in sales-type leases with third parties is recorded
within Receivables, net and Other noncurrent assets on the Consolidated Balance Sheets. The net investment in sales-type
leases with related parties is recorded within Current assets - related parties and Noncurrent assets - related parties 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 leased assets. Management
assesses the net investment in sales-type leases for recoverability quarterly.
Inventories
Inventories consist of materials and supplies to be used in operations, line fill and other NGLs. Cost for materials and supplies
are determined primarily using the weighted-average cost method. Inventories are valued at the lower of cost or net realizable
value.
83
Imbalances
Within our pipelines and storage assets, we experience volume gains and losses due to pressure and temperature changes,
evaporation and variances in meter readings and other measurement methods. Until settled, positive imbalances are recorded
as other current assets and negative imbalances are recorded as accounts payable. Positive and negative imbalances are
settled in cash, settled by physical delivery of volumes from a different source, or tracked and settled in the future.
Investment in Unconsolidated Affiliates
Equity investments in which MPLX exercises significant influence but does not control and is not the primary beneficiary, are
accounted for using the equity method and are reported in Equity method investments on the accompanying Consolidated
Balance Sheets. This includes entities in which we hold majority ownership, but the minority shareholders have substantive
participating rights. 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 the excess related to
goodwill.
Regular evaluation of these investments is appropriate to evaluate any potential need for impairment. MPLX uses evidence of a
loss in value to identify if an investment has an other than a temporary decline. Impairments are recorded through Income from
equity method investments.
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. Expenditures that extend the useful lives of assets are capitalized.
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 flows 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 is at least at the segment level and in some cases for similar assets in the same geographic region
where cash flows can be separately identified. If the sum of the undiscounted future cash flows from the use of the asset group
and its eventual disposition is less than the carrying value of an asset group, an impairment assessment is performed and the
excess of the book value over the fair value 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 on the
Consolidated Statements of Income. Gains on the disposal of property, plant and equipment are recognized when they occur,
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 costs for the construction or development of long-lived assets are capitalized and amortized over the related asset’s
estimated useful life.
Goodwill and Intangibles
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
market approach which is compared to the carrying value of the reporting unit. If the carrying amount of the reporting unit
exceeds its fair value, an impairment loss would be recognized in an amount equal to that excess, limited to the total amount of
goodwill allocated to that reporting unit. The fair value under the income approach is calculated using the expected present value
of future cash flows method. Significant assumptions used in the cash flow forecasts include future net operating margins, future
volumes, discount rates, and future capital requirements. See Note 14 for further details.
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.
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
84
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
An ARO is a legal obligation associated with the retirement of tangible long-lived assets that generally result from the acquisition,
construction, development or normal operation of the asset. The fair value of AROs is recognized in the period in which the
obligations are incurred, if a reasonable estimate of fair value can be made, and added to the carrying amount of the associated
asset. This additional carrying amount is then depreciated over the life of the asset. The liability is determined using a credit
adjusted risk free interest rate and increases due to the passage of time based on the time value of money until the obligation is
settled. AROs have not been recognized for certain 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. As of December 31, 2022 and 2021, MPLX’s
asset retirement obligation was $34 million and $31 million, respectively, and is included on the balance sheet within Other long-
term liabilities.
Derivative Instruments
MPLX may use commodity derivatives to economically hedge a portion of its exposure to commodity price risk. All derivative
instruments (including derivatives embedded in other contracts) are recorded at fair value. MPLX discloses the fair value of all
derivative instruments under the captions Other current assets, Other noncurrent assets, Other current liabilities and Other long-
term liabilities on the Consolidated Balance Sheets. We make a distinction between realized or unrealized gains and losses on
derivatives. During the period when a derivative contract is outstanding, changes in the fair value of the derivative are recorded
as an unrealized gain or loss. When a derivative contract matures or is settled, the previously recorded unrealized gain or loss is
reversed, and the realized gain or loss of the contract is recorded. Changes in the fair value of derivative instruments are
reported on the Consolidated Statements of Income in accounts related to the item whose value or cash flows are being
managed. Derivative instruments are marked to market through Purchased product costs on the Consolidated Statements of
Income.
Certain commodity derivative positions are governed by master netting arrangements and are reflected on the consolidated
balance sheets on a net basis by counterparty. MPLX did not utilize any commodity derivatives during the years ended
December 31, 2022, 2021 and 2020, and therefore did not elect hedge accounting. MPLX has historically elected the normal
purchases and normal sales designation for certain contracts related to the physical purchase of electric power and the sale of
some commodities.
Fair Value Measurement
Financial assets and liabilities recorded at fair value in the Consolidated Balance Sheets are categorized based upon the fair
value hierarchy established by GAAP, which classifies the inputs used to measure fair value into Level 1, Level 2 or Level 3. A
financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the
fair value measurement. The methods and assumptions utilized may produce a fair value that may not be realized in future
periods upon settlement. Furthermore, while MPLX believes its valuation methods are appropriate and consistent with other
market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments
could result in a different estimate of fair value at the reporting date. For further discussion, see Note 15.
Equity-Based Compensation Arrangements
MPLX issues phantom units under the MPLX LP 2018 Incentive Compensation Plan. A phantom unit entitles the grantee a right
to receive a common unit upon the issuance of the phantom unit. The fair value of phantom unit awards granted to employees
and non-employee directors is based on the fair market value of MPLX LP common units on the date of grant. The fair value of
the units awarded is amortized into earnings using a straight-line amortization schedule over the period of service corresponding
with the vesting period. For phantom units that vest immediately and are not forfeitable, equity-based compensation expense is
recognized at the time of grant.
MPLX previously issued performance units under the MPLX LP 2018 Incentive Compensation Plan. 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 paying out in units are accounted for as equity awards. Equity-classified performance units with a market
condition use a Monte Carlo valuation model to calculate a grant date fair value of market conditions. Equity-classified
performance units with a performance condition are valued based on the grant date fair value of the payout deemed most
probable to occur and is adjusted as the expectation for payout changes. All the outstanding performance unit awards have been
settled as of February 1, 2023.
85
To satisfy common unit awards, MPLX may issue new common units, acquire common units in the open market or use common
units already owned by the general partner.
Income Taxes
MPLX is not a taxable entity for United States federal income tax purposes or for the majority of the states that impose an
income tax. Taxes on MPLX’s net income generally are borne by its partners through the allocation of taxable income. MPLX’s
taxable income or loss, which may vary substantially from the net income or loss reported on the Consolidated Statements of
Income, is includable in the federal income tax returns of each partner. MPLX and certain legal entities are, however, taxable
entities under certain state jurisdictions.
MPLX accounts for income taxes under the asset and liability method. Deferred income taxes are recognized for the future tax
consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and
their respective tax basis, capital loss carryforwards and net operating loss and credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates applied to taxable income in the years in which those temporary differences are
expected to be recovered or settled. The effect of any tax rate change on deferred taxes is recognized as tax expense/(benefit)
from continuing operations in the period that includes the enactment date of the tax rate change. Realizability of deferred tax
assets is assessed and, if not more likely than not, a valuation allowance is recorded to reflect the deferred tax assets at net
realizable value as determined by management. All deferred tax balances are classified as long-term in the accompanying
Consolidated Balance Sheets. All changes in the tax bases of assets and liabilities are allocated among operations and items
charged or credited directly to equity.
Distributions
In preparing the Consolidated Statements of Equity, net income attributable to MPLX LP is allocated to Series A and Series B
preferred unitholders based on a fixed distribution schedule, as discussed in Notes 7 and 9, and subsequently allocated to the
limited partner unitholders. Distributions, although earned, are not accrued as a liability until declared. The allocation of net
income attributable to MPLX LP for purposes of calculating net income per limited partner unit is described below.
Net Income Per Limited Partner Unit
MPLX uses the two-class method when calculating the net income per unit applicable to limited partners, because there is more
than one class of participating security. The classes of participating securities include common units, Series A and Series B
preferred units and certain equity-based compensation awards.
Net income attributable to MPLX LP is allocated to the unitholders differently for preparation of the Consolidated Statements of
Equity and the calculation of net income per limited partner unit. In preparing the Consolidated Statements of Equity, net income
attributable to MPLX LP is allocated to Series A and Series B preferred unitholders based on a fixed distribution schedule and
subsequently allocated to remaining unitholders in accordance with their respective ownership percentages. The allocation of net
income attributable to MPLX LP for purposes of calculating net income per limited partner unit is described in Note 8.
In preparing net income per limited partner units, during periods in which a net loss attributable to MPLX is reported or periods in
which the total distributions exceed the reported net income attributable to MPLX’s unitholders, the amount allocable to certain
equity-based compensation awards is based on actual distributions to the equity-based compensation awards. Diluted earnings
per unit is calculated by dividing net income attributable to MPLX’s common unitholders, after deducting amounts allocable to
other participating securities, by the weighted average number of common units and potential common units outstanding during
the period. Potential common units are excluded from the calculation of diluted earnings per unit during periods in which net
income attributable to MPLX’s unitholders, after deducting amounts that are allocable to the outstanding equity-based
compensation awards and preferred units, is a loss, as the impact would be anti-dilutive.
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 deficit 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. Depending on the nature of the
transaction, management may engage an independent valuation specialist to assist with the determination of fair value of the
assets acquired, liabilities assumed, noncontrolling interests, 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 interests, 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 volumes, certain commodity prices, 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
86
estimate will be recorded. Subsequent to the acquisition, and not later than one year from the acquisition date, MPLX will record
any material adjustments to the initial estimate based on new information obtained that would have existed as of the acquisition
date. An 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.
Acquisitions in which the company or business being acquired by MPLX had an existing relationship with MPC may result in the
transaction being considered a transfer between entities under common control. In these situations, MPLX records the assets
acquired and liabilities assumed on its consolidated balance sheets at MPC’s historical carrying value. For the acquiring entity,
transfers of businesses between entities under common control require prior periods to be retrospectively adjusted for those
dates that the entity was under common control.
3. Accounting Standards
Recently Adopted
ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance
In November 2021, the FASB issued guidance requiring disclosures for certain types of government assistance that have been
accounted for by analogy to grant or contribution models. Disclosures include information about the type of transactions,
accounting and the impact on financial statements. MPLX prospectively adopted this standard in the first quarter of 2022. The
adoption of this standard did not have a material impact on our financial statements or disclosures.
4. Acquisitions and Dispositions
Sale of Javelina
On February 12, 2021, MarkWest Energy Operating Company, L.L.C., (“MarkWest Energy”) a wholly owned subsidiary of MPLX,
completed the sale of all of MarkWest Energy’s equity interests in MarkWest Javelina Company L.L.C., MarkWest Javelina
Pipeline Company L.L.C., and MarkWest Gas Services L.L.C. (collectively, “Javelina”) pursuant to the terms of an Equity
Purchase Agreement entered into with a third party on December 23, 2020. The agreement included adjustments for working
capital as well as an earnout provision based on the performance of the assets. No gain or loss was recorded on the sale. The
estimated value of the earnout provision was recorded as a contingent asset shown within Other noncurrent assets on the
Consolidated Balance Sheets as of December 31, 2022 and 2021. Prior to the sale, Javelina was reported within the G&P
segment.
Wholesale Exchange
On July 31, 2020, MPLX entered into a Redemption Agreement (the “Redemption Agreement”) with WRSW, a wholly owned
subsidiary of MPC, pursuant to which MPLX agreed to transfer to WRSW all of the outstanding membership interests in WRW in
exchange for the redemption of MPLX common units held by WRSW. The transaction effects the transfer to MPC of the Western
wholesale distribution business that MPLX acquired as a result of its acquisition of ANDX. Per the terms of the Redemption
Agreement, MPLX redeemed 18,582,088 common units (the “Redeemed Units”) held by WRSW on July 31, 2020. 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.
MPLX canceled the Redeemed Units immediately following the Wholesale Exchange. The carrying value of the net assets of
WRW transferred to MPC was approximately $90 million as of July 31, 2020, resulting in $250 million being recorded to Common
Unit-holder MPC within the Consolidated Statements of Equity, netted against the fair value of the redeemed units. Included
within the $90 million carrying value of the WRW net assets was approximately $65 million of goodwill.

(1) The investment in MarEn Bakken Company LLC includes our 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.
(2) Some investments included within Other have also been deemed to be 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. Therefore, MPLX also reports its portion of
Sherwood Midstream Holdings’ net assets as a component of its investment in Sherwood Midstream. As of December 31, 2022,
MPLX had a 24.55 percent indirect ownership interest in Sherwood Midstream Holdings through Sherwood Midstream.
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. MPLX did not provide any financial support to equity
method investments that it was not contractually obligated to provide during the years ended December 31, 2022, 2021 and
2020. See Note 21 for information on our Guarantees related to indebtedness of equity method investees.
During the first quarter of 2020, we recorded an other-than-temporary impairment for three joint ventures in which we have an
interest. Impairment of these investments was $1,264 million, of which $1,251 million was related to MarkWest Utica EMG,
L.L.C. and its investment in Ohio Gathering Company, L.L.C. The fair value of the investments was determined based upon
applying the discounted cash flow method, which is an income approach. The discounted cash flow fair value estimate is based
on known or knowable information at the interim measurement date. The significant assumptions that were used to develop the
estimate of the fair value under the discounted cash flow method include management’s best estimates of the expected future
88
cash flows, including prices and volumes, the weighted average cost of capital and the long-term growth rate. Fair value
determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As such, the
fair value of these equity method investments represents a Level 3 measurement. As a result, there can be no assurance that the
estimates and assumptions made for purposes of the impairment test will prove to be an accurate prediction of the future. The
impairment was recorded through Income from equity method investments. The impairments were largely due to a reduction in
forecasted volumes gathered and processed by the systems operated by the joint ventures. There were no additional
impairments recorded during the remainder of 2020.

6. Related Party Agreements and Transactions
MPLX engages in transactions with both MPC and certain of its equity method investments as part of its normal business;
however, transactions with MPC make up the majority of MPLX’s related party transactions. Transactions with related parties are
further described below.
MPLX has various long-term, fee-based commercial agreements with MPC. Under these agreements, MPLX provides
transportation, gathering, terminal, fuels distribution, marketing, storage, management, operational and other services to MPC.
MPC has committed to provide MPLX with minimum quarterly throughput volumes on crude oil and refined products and other
fees for storage capacity; operating and management fees; as well as reimbursements for certain direct and indirect costs. MPC
has also committed to provide a fixed fee for 100 percent of available capacity for boats, barges and third-party chartered
equipment under the marine transportation service agreement. In addition, MPLX has obligations to MPC for services provided to
MPLX by MPC under omnibus and employee services type agreements as well as various other agreements as discussed
below.
The commercial agreements with MPC include:
• MPLX has a fuels distribution agreement with MPC under which MPC pays MPLX a tiered monthly volume-based fee
for marketing and selling MPC’s products. This agreement is subject to a minimum quarterly volume and has an initial
term of 10 years, subject to a five-year renewal period under terms to be renegotiated at that time.
• MPLX has various pipeline transportation agreements under which MPC pays MPLX fees for transporting crude and
refined products on MPLX’s pipeline systems. These agreements are subject to minimum throughput volumes under
which MPC will pay MPLX deficiency payments for any period in which they do not ship the minimum committed
volume. Under certain agreements, deficiency payments can be applied as credits to future periods in which MPC ships
volumes in excess of the minimum volume, subject to a limited period of time. These agreements are subject to various
terms and renewal periods.
• MPLX has a marine transportation agreement with an initial term of six years under which MPC pays MPLX fees for
providing marine transportation of crude oil, feedstock and refined petroleum products, and related services. This
agreement is subject to two automatic renewal periods of five years each. This agreement is currently in the first
renewal term.
• MPLX has a month-to-month trucking transportation services agreement under which MPC pays MPLX fees for
gathering barrels and providing trucking, dispatch, delivery and data services.
• MPLX has numerous storage services agreements governing storage services at various types of facilities including
terminals, pipeline tank farms, caverns and refineries, under which MPC pays MPLX per-barrel fees for providing
storage services. Some of these agreements provide MPC with exclusive access to storage at certain locations, such
as storage located at MPC’s refineries or storage in certain caverns. Under these agreements, MPC pays MPLX a per-
barrel fee for such storage capacity, regardless of whether MPC fully utilizes the available capacity. These agreements
are subject to various terms and renewal periods.
• MPLX has multiple terminal services agreements governing certain terminals under which MPC pays MPLX fees for
terminal services. Under these agreements MPC pays MPLX agreed upon fees relating to MPC product receipts,
deliveries and storage as well as any blending, additization, handling, transfers or other related charges. Many of these
agreements are subject to minimum volume throughput commitments, or to various minimum commitments related to
some or all terminal activities, under which MPC pays a deficiency payment for any period in which they do not meet the
minimum commitment. Some of these agreements allow for deficiency payments to be applied as credits to a limited
number of future periods with excess throughput volumes. These agreements are subject to various terms and renewal
periods.
• MPLX has a keep-whole commodity agreement with MPC under which MPC pays us a processing fee for NGLs related
to keep-whole agreements and delivers shrink gas to the producers on our behalf. We pay MPC a marketing fee in
exchange for assuming the commodity risk. The pricing structure under this agreement provides for a base volume
subject to a base rate and incremental volumes subject to variable rates, which are calculated with reference to certain
of our costs incurred as processor of the volumes. The pricing for both the base and incremental volumes are subject to
revision each year. This agreement is subject to automatic three-month renewal periods.
In many cases, agreements are location-based hybrid agreements, containing provisions relating to multiple of the types of
agreements and services described above.
90
Operating Agreements
MPLX operates various pipelines owned by MPC under operating services agreements. Under these operating services
agreements, MPLX receives an operating fee for operating the assets and is reimbursed for all direct and indirect costs
associated with operating the assets. Most of these agreements are indexed for inflation. These agreements range from one to
five years in length and automatically renew unless terminated by either party.
Co-location Services Agreements
MPLX is party to co-location services agreements with MPC’s refineries, under which MPC provides management, operational
and other services to MPLX. MPLX pays MPC monthly fixed fees and direct reimbursements for such services calculated as set
forth in the agreements. These agreements have initial terms of 50 years.
Ground Lease Agreements
MPLX is party to ground lease agreements with certain of MPC’s refineries under which MPLX is the lessee of certain sections of
property which contain facilities owned by MPLX and are within the premises of MPC’s refineries. MPLX pays MPC monthly fixed
fees under these ground leases. These agreements are subject to various terms.
Marine Services Agreements with MPC
MPLX has a management services agreement with MPC under which it provides management services to assist MPC in the
oversight and management of the marine business. MPLX receives fixed annual fees for providing the required services, which
are subject to predetermined annual escalation rates. This agreement is subject to an initial term of five years and automatically
renews for one additional five-year renewal period unless terminated by either party.
Omnibus Agreements
MPLX has omnibus agreements with MPC that address MPLX’s payment of fixed annual fees to MPC for the provision of
executive management services by certain executive officers of the general partner and MPLX’s reimbursement of MPC for the
provision of certain general and administrative services to it. They also provide for MPC’s indemnification to MPLX for certain
matters, including environmental, title and tax matters; as well as our indemnification of MPC for certain matters under these
agreements.
Employee Services Agreements
MPLX has various employee services agreements and secondment agreements with MPC under which MPLX reimburses MPC
for employee benefit expenses, along with the provision of operational and management services in support of both our L&S and
G&P segments’ operations.
Related Party Loan
MPLX is party to a loan agreement (the “MPC Loan Agreement”) with MPC. Under the terms of the MPC Loan Agreement, MPC
extends loans to MPLX on a revolving basis as requested by MPLX and as agreed to by MPC. The borrowing capacity of the
MPC Loan Agreement is $1.5 billion aggregate principal amount of all loans outstanding at any one time. The MPC Loan
Agreement is scheduled to expire, and borrowings under the MPC Loan Agreement are scheduled to mature and become due
and payable on July 31, 2024, provided that MPC may demand payment of all or any portion of the outstanding principal amount
of the loan, together with all accrued and unpaid interest and other amounts (if any), at any time prior to maturity. Borrowings
under the MPC Loan Agreement bore interest at LIBOR plus 1.25 percent or such lower rate as would be applicable to such
loans under the MPLX Credit Agreement as discussed in Note 17. The MPC Loan Agreement was amended effective January 1,
2023 to update the interest rate to one-month term SOFR adjusted upward by 0.10 percent plus 1.25 percent or such lower rate
as would be applicable to such loans under the MPLX Credit Agreement as discussed in Note 17. All other terms of the MPC
Loan Agreement remain unchanged.

Related party sales to MPC primarily consist of crude oil and refined products pipeline and trucking transportation services based
on tariff or contracted rates; storage, terminal and fuels distribution services based on contracted rates; and marine
transportation services. Related party sales to MPC also consist of revenue related to volume deficiency credits.
MPLX also has operating agreements with MPC under which it receives a fee for operating MPC’s retained pipeline assets and a
fixed annual fee for providing oversight and management services required to run the marine business. MPLX also receives
management fee revenue for engineering, construction and administrative services for operating certain of its equity method
investments. Amounts earned under these agreements are classified as Other income-related parties in the Consolidated
Statements of Income.
Certain product sales to MPC net to zero within the consolidated financial statements as the transactions are recorded net due to
the terms of the agreements under which such product was sold. For the years ended December 31, 2022, 2021 and 2020,
these sales totaled $1,002 million, $811 million and $462 million, respectively.
Related Party Expenses
MPC charges MPLX for executive management services and certain general and administrative services provided to MPLX
under the terms of our omnibus agreements (“Omnibus charges”) and for certain employee services provided to MPLX under
employee services agreements (“ESA charges”). Omnibus charges and ESA charges are classified as Rental cost of sales -
related parties, Purchases - related parties, or General and administrative expenses depending on the nature of the asset or
activity with which the costs are associated.
In addition to these agreements, MPLX purchases products from MPC, makes payments to MPC in its capacity as general
contractor to MPLX, and has certain rent and lease agreements with MPC.
Starting in 2020, MPC advanced certain strategic priorities to lay a foundation for long-term success, including plans to optimize
its assets and structurally lower costs in 2021 and beyond, which included an involuntary workforce reduction plan. The
workforce reduction plan, together with employee reductions resulting from MPC's indefinite idling of its Martinez, California and
Gallup, New Mexico refineries, affected approximately 2,050 employees. All of the employees that conduct MPLX’s business are
directly employed by affiliates of MPC, and certain of those employees were affected by MPC’s workforce reductions. During
2020, MPLX reimbursed MPC for $37 million related to severance and employee benefits related expenses that MPC recorded
in connection with its workforce reductions. These costs are shown on the Consolidated Statements of Income as Restructuring
expenses. There were no similar costs in 2021 or 2022.
For the years ended December 31, 2022, 2021 and 2020, General and administrative expenses incurred from MPC totaled $235
million, $250 million and $254 million, respectively.
Some charges incurred under the omnibus and employee service agreements are related to engineering services and are
associated with assets under construction. These charges are added to Property, plant and equipment, net on the Consolidated
Balance Sheets. For 2022, 2021 and 2020, these charges totaled $70 million, $55 million and $97 million, respectively.
92
Related Party Assets and Liabilities
Assets and liabilities with related parties appearing in the Consolidated Balance Sheets are detailed in the table below. This table
identifies the various components of related party assets and liabilities, including those associated with leases (see Note 20 for
additional information) and deferred revenue on minimum volume commitments. If MPC fails to meet its minimum committed
volumes, MPC will pay MPLX a deficiency payment based on the terms of the agreement. The deficiency amounts received
under these agreements (excluding payments received under agreements classified as sales-type leases) are recorded as
Current liabilities - related parties. In many cases, MPC may then apply the amount of any such deficiency payments as a credit
for volumes in excess of its minimum volume commitment in future periods under the terms of the applicable agreements. MPLX
recognizes related party revenues for the deficiency payments when credits are used for volumes in excess of minimum
quarterly volume commitments, where it is probable the customer will not use the credit in future periods or upon the expiration of
the credits. The use or expiration of the credits is a decrease in Current liabilities - related parties. Deficiency payments under
agreements that have been classified as sales-type leases are recorded as a reduction against the corresponding lease
receivable. In addition, capital projects MPLX undertakes at the request of MPC are reimbursed in cash and recognized as
revenue over the remaining term of the applicable agreements or in some cases, as a contribution from MPC.

Unit Repurchase Program
On November 2, 2020, MPLX announced the board authorization of a unit repurchase program for the repurchase of up to
$1 billion of MPLX’s outstanding common units held by the public, which was exhausted during the fourth quarter of 2022. On
August 2, 2022, we announced the board authorization for the repurchase of up to an additional $1 billion of MPLX common
units held by the public. This unit repurchase authorization has no expiration date. We 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. The table below summarizes the repurchases made under the unit repurchase program for the
years ended December 31, 2022, 2021 and 2020:

Issuance of Additional Securities
The Sixth Amended and Restated Agreement of Limited Partnership of MPLX LP, dated as of February 1, 2021 (“Partnership
Agreement”), authorizes MPLX to issue an unlimited number of additional securities for the consideration and on the terms and
conditions determined by the general partner without the approval of the unitholders.
Cash Distributions
Total distributions for the twelve months ended December 31, 2022, 2021 and 2020 are summarized in the table below. The
2021 period includes a supplemental distribution amount of $0.575 per common unit (the “Supplemental Distribution Amount”)

9. Series A Preferred Units
Private Placement of Preferred Units
On May 13, 2016, MPLX completed the private placement of approximately 30.8 million 6.5 percent Series A Convertible
preferred units for a cash purchase price of $32.50 per unit. The aggregate net proceeds of approximately $984 million from the
sale of the Series A preferred units were used for capital expenditures, repayment of debt and general business purposes.
Preferred Unit Distribution Rights
The Series A preferred units rank senior to all common units and pari passu with all Series B preferred units with respect to
distributions and rights upon liquidation. The holders of the Series A preferred units are entitled to receive, when and if declared
by the board, a quarterly distribution equal to the greater of $0.528125 per unit or the amount of distributions they would have
received on an as converted basis, including any supplemental distributions made to common unitholders. On January 25, 2023,
MPLX declared a quarterly cash distribution of $0.7750 per common unit for the fourth quarter of 2022. Holders of the Series A
preferred units received the common unit rate in lieu of the lower $0.528125 base amount.
The holders may convert their Series A preferred units into common units at any time, in full or in part, subject to minimum
conversion amounts and conditions. After the fourth anniversary of the issuance date, MPLX may convert the Series A preferred
units into common units at any time, in whole or in part, subject to certain minimum conversion amounts and conditions, if the
closing price of MPLX common units is greater than $48.75 for the 20-day trading period immediately preceding the conversion
notice date. The conversion rate for the Series A preferred units shall be the quotient of (a) the sum of (i) $32.50, plus (ii) any
unpaid cash distributions on the applicable preferred unit, divided by (b) $32.50, subject to adjustment for unit distributions, unit
splits and similar transactions. The holders of the Series A preferred units are entitled to vote on an as-converted basis with the
common unitholders and have certain other class voting rights with respect to any amendment to the MPLX partnership
agreement that would adversely affect any rights, preferences or privileges of the preferred units. In addition, upon certain events
involving a change of control, the holders of preferred units may elect, among other potential elections, to convert their Series A
preferred units to common units at the then applicable change of control conversion rate.
Preferred Units Outstanding
During the year ended December 31, 2021, certain Series A preferred unitholders exercised their rights to convert their Series A
preferred units into 93,108 common units. As a result of these transactions, approximately 29.5 million Series A preferred units
remain outstanding as of December 31, 2022.
97
Financial Statement Presentation
The Series A preferred units are considered redeemable securities under GAAP due to the existence of redemption provisions
upon a deemed liquidation event, which is outside MPLX’s control. Therefore, they are presented as temporary equity in the
mezzanine section of the Consolidated Balance Sheets. The Series A preferred units have been recorded at their issuance date
fair value, net of issuance costs. Income allocations increase the carrying value and declared distributions decrease the carrying
value of the Series A preferred units. As the Series A preferred units are not currently redeemable and not probable of becoming
redeemable, adjustment to the initial carrying amount is not necessary and would only be required if it becomes probable that the
Series A preferred units would become redeemable.
For a summary of changes in the redeemable preferred balance for the years ended December 31, 2022, 2021 and 2020, see
the Consolidated Statements of Equity.

MPLX has a concentration of trade receivables due from customers in the same industry: MPC, integrated oil companies, natural
gas exploration and production companies, independent refining companies and other pipeline companies. These concentrations
of customers may impact MPLX’s overall exposure to credit risk as they may be similarly affected by changes in economic,
regulatory and other factors. MPLX manages its exposure to credit risk through credit analysis, credit limit approvals and
monitoring procedures; and for certain transactions, it may request letters of credit, prepayments or guarantees.

Includes property, plant and equipment impairment charges recorded during the respective period, as discussed below.
We capitalize interest as part of the cost of major projects during the construction period. Capitalized interest totaled $9 million,
$14 million and $39 million as of the years ended December 31, 2022, 2021 and 2020, respectively.
In the second quarter of 2021, we recognized impairment expense of $42 million within our G&P segment related to our
continued emphasis on portfolio optimization with the divestiture of several non-core assets and the closure of other non-core
assets.
During the first quarter of 2020, we identified an impairment trigger relating to asset groups within our Western G&P reporting
unit as a result of significant impacts to forecasted cash flows for these asset groups resulting from the deterioration in the
economy and the environment in which MPLX and its customers operate, as well as a sustained decrease in unit price. 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. After assessing each asset group within the Western G&P reporting
unit for impairment, only the East Texas G&P asset group resulted in the fair value of the underlying assets being less than the
carrying value. As a result, an impairment of $174 million was recorded to Impairment expense on the Consolidated Statements
of Income. Fair value of the assets 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, the estimated useful
life of the asset group and discount rate. 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. 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 our 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.
14. Goodwill and Intangibles
Goodwill
MPLX 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.
Our reporting units are one level below our operating segments and are determined based on the way in which segment
management operates and reviews each operating segment. We have five reporting units, three of which have goodwill allocated
to them. For the annual impairment assessment as of November 30, 2022, management performed only a qualitative
assessment for two reporting units as we determined it was more likely than not that the fair values of the reporting units
101
exceeded their carrying values. The fair value of the crude gathering reporting unit for which a quantitative assessment was
performed was determined based on applying both a discounted cash flow, or income approach, as well as a market approach
which resulted in the fair value of the reporting unit exceeding its carrying value by greater than 10 percent. The significant
assumptions used to develop the estimate of the fair value under the discounted cash flow method included management’s best
estimates of the discount rate of 10.1 percent as well as estimates of future cash flows, which are impacted primarily by producer
customers’ 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 annual goodwill impairment test will prove to be an
accurate prediction of the future. The fair value measurements for the individual reporting units represent Level 3 measurements.
Total goodwill at December 31, 2022 was $7,645 million and no impairment was recorded as a result of our November 30, 2022
annual goodwill impairment analysis.
During the first quarter of 2020, we determined that an interim impairment analysis of the goodwill recorded was necessary
based on consideration of a number of first quarter events and circumstances. Our producer customers in our Eastern G&P
region reduced production forecasts and drilling activity in response to the global economic downturn. Additionally, a decline in
NGL prices impacted our future revenue forecast. After performing our evaluations related to the interim impairment of goodwill
during the first quarter of 2020, we recorded an impairment of $1,814 million within the Eastern G&P reporting unit, which was
recorded to “Impairment expense” on the Consolidated Statements of Income. The impairment was primarily driven by additional
guidance related to the slowing of drilling activity, which reduced production growth forecasts from our producer customers. The
interim impairment assessment of the remaining reporting units with goodwill resulted in the fair value of the reporting units
exceeding their carrying value. The fair value of our reporting units was determined using the same methodology and significant
assumptions described above and included management’s best estimates of the discount rate, which ranged from 9.5 percent to
11.5 percent.

expense attributable to the G&P segment for the years ended December 31, 2022 and 2021 was $90 million and $92 million, respectively.
During the first quarter of 2020, we also determined that an impairment analysis of intangibles within our Western G&P reporting
unit was necessary. See Note 13 for additional information regarding our assessment around the Western G&P reporting unit,
and more specifically our East Texas G&P asset group. The fair value of the intangibles in our East Texas G&P asset group were
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
102
the discount rate. After performing our evaluations related to the impairment of intangible assets associated with our East Texas
G&P asset group during the first quarter of 2020, we recorded an impairment of $177 million to Impairment expense on the
Consolidated Statements of Income related to our customer relationships.

Fair value measurements and disclosures relate primarily to MPLX’s derivative positions as discussed in Note 16.
Level 3 instruments relate to a derivative liability for a natural gas purchase commitment embedded in a keep-whole processing
agreement. The fair value calculation for these Level 3 instruments uses 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 renewal term of the gas purchase commitment
and 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, respectively. Beyond the embedded derivative discussed above,
we had no outstanding commodity derivative contracts as of December 31, 2022 or December 31, 2021.

Fair Values – Non-recurring
Non-recurring fair value measurements and disclosures relate primarily to MPLX’s sales-type leases as discussed in Note 20.
The net investment in sales-type leases is 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.
Fair Values – Reported
We believe the carrying value of our other financial instruments, including cash and cash equivalents, receivables, receivables
from related parties, lease receivables, lease receivables from related parties, accounts payable, and payables to related parties,
approximate fair value. MPLX’s fair value assessment incorporates a variety of considerations, including the duration of the
instruments, MPC’s investment-grade credit rating and the historical incurrence of and expected future insignificance of bad debt
expense, which includes an evaluation of counterparty credit risk. The recorded value of the amounts outstanding under the bank
revolving credit facility, if any, approximates fair value due to the variable interest rate that approximates current market rates.
Derivative instruments are recorded at fair value, based on available market information.

The fair value of MPLX’s debt is estimated based on recent market non-binding indicative quotes. The debt fair values are
considered Level 3 measurements. The following table summarizes the fair value and carrying value of our third-party debt,

16. Derivative Financial Instruments
For the years 2022, 2021 and 2020, MPLX had no commodity contracts beyond the embedded derivative discussed below.
Embedded Derivative - MPLX has a natural gas purchase commitment embedded in a keep-whole processing agreement with a
producer customer in the Southern Appalachian region expiring in December 2027. The customer has the unilateral option to
extend the agreement for one five-year term through December 2032. For accounting purposes, the natural gas purchase
commitment and the term extending option has been aggregated into a single compound embedded derivative. The probability of
the customer exercising its option is determined based on assumptions about the customer’s potential business strategy decision
points that may exist at the time they would elect whether to renew the contract. The changes in fair value of this compound
embedded derivative are based on the difference between the contractual and index pricing, the probability of the producer
customer exercising its option to extend and the estimated favorability of these contracts compared to current market conditions.
The changes in fair value are recorded in earnings through Purchased product costs on the Consolidated Statements of Income.
For further information regarding the fair value measurement of derivative instruments, see Note 15. See Note 2 for a discussion
of derivatives MPLX may use and the reasons for them. As of December 31, 2022 and 2021, the estimated fair value of this
contract was a liability of $61 million and $108 million, respectively.
As of December 31, 2022 and 2021, there were no derivative assets or liabilities that were offset on the Consolidated Balance
Sheets. The impact of MPLX’s derivative instruments on its Consolidated Balance Sheets is summarized below:

Credit Agreements
MPLX Credit Agreement
On July 7, 2022, MPLX entered into a new five-year credit agreement (the “MPLX Credit Agreement”) to replace the previous
$3.5 billion credit facility that was scheduled to expire July 2024. The new MPLX Credit Agreement matures July 7, 2027 and,
among other things, provides for a $2 billion unsecured revolving credit facility and letter of credit issuing capacity under the
facility of up to $150 million. Letter of credit issuing capacity is included in, not in addition to, the $2 billion borrowing capacity.
The financial covenants of the MPLX Credit Agreement are substantially the same as those contained in the previous credit
agreement. Borrowings under the new 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.
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 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. MPLX is charged various fees and expenses in connection with the agreement, including administrative agent
fees, commitment fees on the unused portion of the facility and fees with respect to issued and outstanding letters of credit. The
applicable margins to the benchmark interest rates and certain fees fluctuate based on the credit ratings in effect from time to
time on MPLX’s long-term debt.
The MPLX Credit Agreement contains certain representations and warranties, affirmative and restrictive covenants and events of
default that MPLX considers 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

On February 9, 2023, MPLX issued $1.6 billion aggregate principal amount of notes, consisting of $1.1 billion principal amount of
5.00 percent senior notes due 2033 (the “2033 Senior Notes”) and $500 million principal amount of 5.65 percent senior notes
due 2053 (the “2053 Senior Notes”). The 2033 Senior Notes were offered at a price to the public of 99.170 percent of par with
interest payable semi-annually in arrears, commencing on September 1, 2023. The 2053 Senior Notes were offered at a price to
the public of 99.536 percent of par with interest payable semi-annually in arrears, commencing on September 1, 2023. MPLX
used $600 million of the net proceeds to redeem all of the outstanding Series B preferred units. We also provided notice to
redeem all of MPLX’s and MarkWest’s $1.0 billion aggregate principal amount of 4.50 percent senior notes due July 2023.
On March 14, 2022, MPLX issued $1.5 billion aggregate principal amount of 4.950 percent senior notes in a public offering due
March 2052 (the “2052 Senior Notes”). The 2052 Senior Notes were offered at a price to the public of 98.982 percent of par with
interest payable semi-annually in arrears, commencing on September 14, 2022. The net proceeds were used to repay amounts
outstanding under the MPC Intercompany Loan Agreement and the MPLX Credit Agreement as well as for general partnership
purposes.
On August 11, 2022, MPLX issued $1.0 billion aggregate principal amount of 4.950 percent senior notes due September 2032
(the “2032 Senior Notes”) in an underwritten public offering. The 2032 Senior Notes were offered at a price to the public of
99.433 percent of par with interest payable semi-annually in arrears, commencing on March 1, 2023. The net proceeds were
used to redeem all of the 3.500 percent senior notes due December 2022 and all of the 3.375 percent senior notes due March
2023, as discussed below.
On August 25, 2022, MPLX redeemed all of the $500 million 3.500 percent senior notes due December 2022, $14 million of
which was issued by Andeavor Logistics LP, at 100.101 percent of the aggregate principal amount, plus accrued and unpaid
interest to, but not including the redemption date. On September 15, 2022, MPLX redeemed all of the $500 million 3.375 percent
senior notes due March 2023 at 100 percent of the aggregate principal amount. The impact of these debt extinguishments was
not material to the Consolidated Statements of Income.
On January 15, 2021, MPLX redeemed all of the $750 million outstanding aggregate principal amount of 5.250 percent senior
notes, due January 15, 2025, including approximately $42 million aggregate principal amount of senior notes issued by ANDX, at
a price equal to 102.625 percent of the principal amount. The payment of $20 million related to the note premium, offset by the
immediate expense recognition of $12 million of unamortized debt premium and issuance costs, resulted in a loss on
extinguishment of debt of $8 million that is included on the Consolidated Statements of Income as Other financial costs.
107
Subordination of Senior Notes
The MPLX senior notes are direct, unsecured unsubordinated obligations of MPLX LP. As such, they rank equally in right of
payment with all of MPLX LP’s other unsubordinated debt and are not guaranteed by any of MPLX LP’s subsidiaries. The MPLX
notes are effectively junior to MPLX LP’s secured indebtedness, if any, to the extent of the value of the relevant collateral. The
MPLX notes are not obligations of any of MPLX’s subsidiaries and are effectively subordinated to all indebtedness and other
obligations of such subsidiaries. The MPLX notes may be redeemed, in whole or part, at any time at the option of MPLX at a
redemption price specified in the indenture governing the applicable notes, plus accrued and unpaid interest to the redemption
date. The indenture governing the MPLX senior notes does not limit the amount of debt that MPLX may issue under the
indenture, nor the amount of other debt that MPLX or any of its subsidiaries may issue or guaranty.
The ANDX senior notes are non-recourse to MPLX and its subsidiaries other than ANDX, the general partner of ANDX and other
subsidiaries, if any, of ANDX that are a co-issuer or guarantor of the ANDX senior notes. The MarkWest senior notes are non-
recourse to MPLX and its subsidiaries other than MarkWest, the general partner of MarkWest and other subsidiaries, if any, of
MarkWest that are a co-issuer or guarantor of the MarkWest senior notes.

Contract Balances
Contract assets typically relate to deficiency payments related to minimum volume commitments and aid in construction
agreements where the revenue recognized and MPLX’s rights to consideration for work completed exceeds the amount billed to
the customer. Contract assets are included in Other current assets and Other noncurrent assets on the Consolidated Balance
Sheets.
Contract liabilities, which we present as Deferred revenue and Long-term deferred revenue, typically relate to advance payments
for aid in construction agreements and deferred customer credits associated with makeup rights and minimum volume
commitments. Related to minimum volume commitments, breakage is estimated and recognized into service revenue in
instances where it is probable the customer will not use the credit in future periods. We classify contract liabilities as current or
long-term based on the timing of when we expect to recognize revenue.
Receivables, net primarily relate to our commodity sales. Portions of the Receivables, net balance are attributed to the sale of
commodity product controlled by MPLX prior to sale while a significant portion of the balance relates to the sale of commodity
product on behalf of our producer customers. The sales and related Receivables, net are commingled and excluded from the
table below. MPLX remits the net sales price back to our producer customers upon completion of the sale. Each period end,
certain amounts within accounts payable relate to our payments to producer customers. Such amounts are not deemed material
at period end as a result of when we settle with each producer.

Remaining Performance Obligations
The table below includes estimated revenue expected to be recognized in the future related to performance obligations that are
unsatisfied (or partially unsatisfied) at the end of the reporting period.
As of December 31, 2022, unsatisfied performance obligations included in the Consolidated Balance Sheets are $360 million and
will be recognized as revenue as the obligations are satisfied, which is expected to occur over the next 21 years. A portion of this
amount is not disclosed in the table below as it is deemed variable consideration due to volume variability. Additionally, we do not
disclose information on the future performance obligations for any contract with an original expected duration of one year or less.

field equipment, storage facilities and transportation equipment, while our related party leases primarily relate to ground leases
associated with our refining logistics assets. Our remaining lease terms range from less than one to 96 years. Some long-term
leases include renewal options ranging from one to 50 years and, in certain leases, also include purchase options. Renewal
options and termination options were not included in the measurement of ROU assets and lease liabilities since it was
determined they were not reasonably certain to be exercised.

Based on the terms of fee-based transportation and storage services agreements with MPC and third parties, MPLX is
considered to be the lessor under several operating lease arrangements in accordance with GAAP. These agreements have
remaining terms ranging from less than one year to 10 years with renewal options ranging from one year to five years, and some
agreements having multiple renewal options. We are also considered to be the lessor under several operating lease agreements
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.
Lease revenues included on the Consolidated Statements of Income during 2022, 2021 and 2020 were as follows:

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.
We 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 the related third-party agreement under ASC 842. Additionally, during the twelve months ended December 31, 2022, 2021 and
2020, we executed amendments to certain related party storage, transportation and terminal service agreements between MPLX
and MPC to provide for reimbursements for projects, changes to minimum volume commitments or to extend the term of the
agreement. The changes required the embedded leases within these agreements to be reassessed under ASC 842. As a result
of these lease assessments, certain leases were reclassified from an operating lease to a sales-type lease. Accordingly, the
underlying property, plant and equipment, net, and associated deferred revenue, if any, were derecognized and the present value
of the future lease payments and the unguaranteed residual value of the assets were recorded as a net investment in sales-type
lease during the respective periods.

21. Commitments and Contingencies
MPLX is 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 MPLX has not recorded a liability, MPLX is 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
MPLX is subject to federal, state and local 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. Penalties may be imposed for non-compliance.
At December 31, 2022 and 2021, accrued liabilities for remediation totaled $17 million and $23 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.
MPLX is involved in environmental enforcement matters arising in the ordinary course of business. While the outcome and
impact to MPLX cannot be predicted with certainty, management believes the resolution of these environmental matters will not,
individually or collectively, have a material adverse effect on its consolidated results of operations, financial position or cash
flows.
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
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.
MPLX is 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 MPLX cannot be predicted with certainty, management believes the resolution of these other
115
lawsuits and proceedings will not, individually or collectively, have a material adverse effect on its consolidated financial position,
results of operations or cash flows.
Guarantees
Over the years, MPLX has sold various assets in the normal course of its 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 MPLX to perform upon the occurrence of a triggering
event or condition. These guarantees and indemnifications are part of the normal course of selling assets. MPLX is 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.
We hold a 9.19 percent indirect interest in 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 EIS has been delayed and the Army Corps
currently 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.
We have entered into a Contingent Equity Contribution Agreement whereby MPLX LP, along with the other joint venture owners
in the Bakken Pipeline system, has agreed to make equity contributions to the joint venture upon certain events occurring to
allow the entities that own and operate the Bakken Pipeline system to satisfy their senior note payment obligations. The senior
notes were issued to repay amounts owed by the pipeline companies to fund the cost of construction of the Bakken Pipeline
system.
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 one percent 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.
Contractual Commitments and Contingencies
At December 31, 2022, MPLX’s contractual commitments to acquire property, plant and equipment totaled $165 million. These
commitments were primarily related to G&P plant expansions. In addition, from time to time and in the ordinary course of
business, MPLX and its affiliates provide guarantees of MPLX’s subsidiaries payment and performance obligations in the G&P
segment. Certain natural gas processing and gathering arrangements require MPLX to construct new 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 producers may have the right to
cancel the processing arrangements if there are significant delays that are not due to force majeure. As of December 31, 2022,
management does not believe there are any indications that MPLX will not be able to meet the construction milestones, that
force majeure does not apply or that such fees and charges will otherwise be triggered.
116
Other Contractual Obligations
MPLX executed various third-party transportation and terminalling agreements that obligate us to minimum volume, throughput
or payment commitments over the remaining terms of the agreements, which range from less than one year to nine years. After
the minimum volume commitments are met in the transportation and terminalling agreements, MPLX pays additional amounts
based on throughput. There are escalation clauses in the transportation and terminalling agreements, which are based on
Consumer Price Index adjustments. The minimum future payments under these agreements as of December 31, 2022 are as
follows:

On February 9, 2023, MPLX issued $1.6 billion aggregate principal amount of notes, consisting of $1.1 billion principal amount of
5.00 percent senior notes due 2033 and $500 million principal amount of 5.650 percent senior notes due 2053. The 2033 Senior
Notes and 2053 Senior Notes will mature on March 1, 2033 and March 1, 2053, respectively. The 2033 Senior Notes were
offered at a price to the public of 99.170 percent with interest payable semi-annually in arrears, commencing on September 1,
2023. The 2053 Senior Notes were offered at a price to the public of 99.536 percent with interest payable semi-annually in
arrears, commencing on September 1, 2023.
On February 15, 2023, MPLX used $600 million of the net proceeds from the 2033 Senior Notes and the 2053 Senior Notes to
redeem all of the outstanding Series B preferred units. We also provided notice to redeem all of MPLX’s and MarkWest’s
$1.0 billion aggregate principal amount of 4.50 percent senior notes due July 2023.

GOVERNANCE FRAMEWORK
Our Governance Principles provide the functional framework of our Board. They address, among other things, the primary roles,
responsibilities and oversight functions of the Board and its committees, director independence, committee composition, the
process for director selection, director qualifications, outside commitments, director compensation and director retirement and
resignation. Our Governance Principles provide that directors generally must retire from service once they reach age 75, unless
otherwise approved by the general partner’s sole member.
Our Code of Business Conduct, which applies to all of our directors, officers and employees, defines our expectations for ethical
decision-making, accountability and responsibility. Our Code of Ethics for Senior Financial Officers, which is specifically
applicable to our President and Chief Executive Officer, Executive Vice President and Chief Financial Officer, Vice President and
Controller, Vice President and Treasurer and other leaders performing similar functions, affirms the principle that the honesty,
integrity and sound judgment of our senior executives with responsibility for preparation and certification of our financial
statements are essential to the proper functioning and success of our company. These codes are available on our website as
noted below, and printed copies are available upon request to our Corporate Secretary. We would post on our website any
amendments to, or waivers from, either of these codes requiring disclosure under applicable rules within four business days
following any such amendment or waiver.
Our Whistleblowing as to Accounting Matters Policy establishes procedures for the receipt, retention and treatment of complaints
we receive regarding accounting, internal accounting controls or auditing matters, and provides for the confidential, anonymous
submission of concerns by employees or others regarding questionable accounting or auditing matters.
Copies of the Governance Principles, the Code of Business Conduct, the Code of Ethics for Senior Financial Officers, and the
Whistleblowing as to Accounting Matters Policy are available on the “Corporate Governance” page of our website at
www.mplx.com/Investors/Corporate_Governance/.
DIRECTOR INDEPENDENCE AND QUALIFICATIONS
The Board currently consists of ten directors. The NYSE does not require a publicly traded limited partnership like us to have a
majority of independent directors on our Board. We are, however, required to have an Audit Committee comprised of at least
three independent directors. The Board considered all relevant facts and circumstances including, without limitation, transactions
between the director directly or organizations with which the director is affiliated and us, any service by the director on the board
of a company with which we conduct business, and the frequency and dollar amounts associated with these transactions, and
has determined that each of Ms. Breves and Messrs. Helms, Peiffer, Sandman, Semple, Stice and Surma meets the
independence standards in our Governance Principles, has no material relationship with us other than as a director, and satisfies
the independence requirements of the NYSE and applicable SEC rules.
123
As stated above, our Governance Principles address qualifications for serving as a director. Directors must actively be engaged
in their profession or otherwise regularly involved in business, professional or academic communities, and must normally be
available for meetings of the Board and its committees. Directors are encouraged to serve on the boards of directors of other
companies; however, each director’s outside directorships must be limited to a number that does not interfere with his or her
ability to meet the responsibilities and expectations of service on our Board. Messrs. Semple, Stice and Surma currently serve on
MPC’s board of directors. As MPLX GP LLC is a wholly owned subsidiary of MPC, we view such service as an extension of
service on our Board for purposes of assessing the level of outside public board commitments.
BOARD LEADERSHIP STRUCTURE
Our Governance Principles provide the Board with the flexibility to determine from time to time the optimal leadership for the
Board depending upon our particular needs and circumstances. The Board has determined that Mr. Hennigan is in the best
position at this time to serve as Chairman due to his extensive knowledge of all aspects of our business, as well as our continued
relationship with MPC.
When the CEO or another management director is elected Chairman, the Board has appointed an independent director as “Lead
Director” to provide independent director oversight and preside over executive sessions of the Board or other Board meetings
when the Chairman is absent.
Mr. Sandman, an independent director, currently serves as Lead Director of the Board. The Board believes that this leadership
structure is in the best interests of our unitholders and us at this time because it strikes an effective balance between
management and independent director participation in the Board process.
COMMITTEES OF THE BOARD
Our Board has a standing Audit Committee and Conflicts Committee, and may have such other committees as the Board shall
determine from time to time. Each committee operates under a written charter, which is available on the “Corporate Governance”
page of our website at www.mplx.com/Investors/Corporate_Governance/Board_Committees_and_Charters/. Each charter
requires the applicable committee to annually assess and report to the Board on the adequacy of the charter.
We have additionally established an executive committee of the board, comprised of Messrs. Hennigan and Sandman, to
address matters that may arise between meetings of the Board. This executive committee may exercise the powers and
authority of the Board subject to specific limitations consistent with applicable law.
Because we are a limited partnership, we are not required to have a compensation committee or a nominating/corporate
governance committee.
Audit Committee
Our Audit Committee assists the Board in its oversight of the integrity of our financial statements, and our compliance with legal
and regulatory requirements and our disclosure controls and procedures. Our Audit Committee has the sole authority to retain
and terminate our independent registered public accounting firm, approve all auditing services and related fees and the terms
thereof and pre-approve any non-audit services to be rendered by our independent registered public accounting firm. Our Audit
Committee also is responsible for confirming the independence and objectivity of our independent registered public accounting
firm. Our independent registered public accounting firm has unrestricted access to our Audit Committee.
Our Audit Committee is comprised of Messrs. Peiffer (Chair), Helms and Sandman and Ms. Breves. The Board has determined
that each member of the Audit Committee meets the independence requirements of the NYSE and the SEC, as applicable, and
that each is financially literate. The Board also has determined that each of Messrs. Peiffer and Sandman and Ms. Breves
qualifies as an “audit committee financial expert,” as defined by SEC rules, based on the attributes, education and experience
further described in each director’s biography under “Directors and Executive Officers of MPLX GP LLC,” above.
124
Audit Committee Report
The Audit Committee has reviewed and discussed MPLX’s audited financial statements and its report on internal control over
financial reporting for 2022 with the management of MPLX GP LLC, MPLX’s general partner. The Audit Committee discussed
with the independent auditors, PricewaterhouseCoopers LLP (“PwC”), the matters required to be discussed by the applicable
requirements of the Public Company Accounting Oversight Board and the SEC. The Audit Committee has received the written
disclosures and the letter from PwC required by the applicable requirements of the Public Company Accounting Oversight Board
regarding PwC’s communications with the Audit Committee concerning independence, and has discussed with PwC its
independence. Based on the review and discussions referred to above, the Audit Committee recommended to the Board that the
audited financial statements and the report on internal control over financial reporting for MPLX LP be included in MPLX’s Annual
Report on Form 10-K for the year ended December 31, 2022, for filing with the SEC.
Garry L. Peiffer, Chair
Christine S. Breves
Christopher A. Helms
Dan D. Sandman
Conflicts Committee
Our Conflicts Committee reviews specific matters that may involve conflicts of interest in accordance with the terms of our
Partnership Agreement. Any matters approved by our Conflicts Committee in good faith will be deemed to be approved by all of
our partners and not a breach by our general partner of any duties it may owe our unitholders or us. The members of our
Conflicts Committee may not be officers or employees of our general partner or directors, officers or employees of its affiliates,
and must meet the independence and experience standards established by the NYSE and the SEC to serve on an audit
committee. In addition, the members of our Conflicts Committee may not own any interest in our general partner or any interest
in us, our subsidiaries or our affiliates other than common units or awards under our incentive compensation plan.
Our Conflicts Committee is comprised of Messrs. Helms (Chair) and Sandman and Ms. Breves. The Board has determined that
each member of the Conflicts Committee meets the independence requirements of the NYSE and the SEC, as applicable.
BOARD ORIENTATION AND EDUCATION
We maintain an orientation program for new directors that includes meetings with and presentations by senior management. This
offers a new director the opportunity to receive one-on-one time with management to discuss various aspects of our business. In
addition, we encourage directors to attend, at our expense, director continuing education programs. In 2022, various of our
directors attended symposiums sponsored by outside organizations that are designed as continuing director education on many
topics relevant to public company board service. We also provide ongoing director education through presentations at Board and
committee meetings.
COMMUNICATING WITH THE BOARD
All interested parties, including unitholders, may communicate directly with the Board, the Chairs of the Board’s standing
committees and the independent directors as follows:
Mail: Communications may be sent by regular mail to our principal executive offices, to the attention of the Corporate
Secretary, MPLX GP LLC, 200 East Hardin Street, Findlay, OH 45840.

Item 11. Executive Compensation
COMPENSATION DISCUSSION AND ANALYSIS
This Compensation Discussion and Analysis (“CD&A”) provides an overview of our executive compensation program and
explains how and why 2022 compensation decisions were made for our named executive officers listed below (our “NEOs”). We
recommend this section be read together with the tables and related disclosures in the “Executive Compensation Tables” section
of this Item 11.
NAMED EXECUTIVE OFFICERS
This CD&A focuses on the compensation for our NEOs, which for 2022 included our Chairman, President and Chief Executive
Officer (“CEO”), our Executive Vice President and Chief Financial Officer (“CFO”), our three other most highly compensated
executive officers, and one former executive officer who now serves as an executive officer of MPC:
Name

Michael J. Hennigan
Chairman, President and CEO
John J. Quaid

Gregory S. Floerke
Thomas Kaczynski
Timothy J. Aydt
Executive Vice President and CFO
General Counsel
Executive Vice President and Chief Operating Officer
Senior Vice President, Finance and Treasurer
Executive Vice President, Refining, of MPC (effective September 1, 2022; previously, MPLX
Executive Vice President and Chief Commercial Officer)
COMPENSATION DECISIONS AND ALLOCATION
Compensation Allocation
We do not directly employ any of the personnel responsible for managing and operating our business, including our NEOs.
Instead, we contract with MPC to provide the necessary personnel, all of whom are directly employed by MPC or one of its
affiliates. Under the terms of an omnibus agreement, described in Item 8. Financial Statements and Supplementary Data, Note 6
of this report, we pay MPC a fixed amount in return for services provided by our NEOs, which totaled approximately $12.2 million
for 2022. Although we report in this CD&A 100% of the compensation our NEOs receive for their service to MPC and its affiliates
(including us), the only direct compensation we provide to our NEOs is in the form of long-term equity incentive awards, which
are described in detail in the “2022 Grants of Plan-Based Awards” table and accompanying narrative below.
Compensation Decisions
We maintain the MPLX LP 2018 Incentive Compensation Plan (the “MPLX 2018 Plan”) for the benefit of eligible officers,
employees and directors of our general partner and its affiliates, including MPC, who provide services to our business. The
Compensation and Organization Development Committee of MPC’s board of directors (“MPC’s Compensation Committee”),
currently comprised of four independent directors, recommends awards under the MPLX 2018 Plan for our NEOs, subject to
approval by our Board, which typically considers such awards on an annual basis. Our Board makes all final determinations with
respect to awards under the MPLX 2018 Plan. All other compensation decisions for our NEOs are made by MPC's
Compensation Committee and are not subject to approval by our Board or us.
Compensation Consultant
Our Board does not have a standing compensation committee and has not hired its own compensation consultant. MPC’s
Compensation Committee engages an independent compensation consultant to provide compensation consulting services and
comparative compensation information.
126
EXECUTIVE COMPENSATION PROGRAM FOR 2022
2022 Base Salary
MPC pays our NEOs a base salary for their services to MPC and its affiliates, including us. In setting base salary for 2022,
MPC’s Compensation Committee evaluated compensation reference group data, each individual’s performance and
contributions over the prior year, where applicable, demonstrated performance and skills acquired over the course of each NEO’s
career and MPC’s succession-planning needs. Taking these matters into consideration, MPC’s Compensation Committee
approved the following 2022 base salaries for our NEOs:

As noted above in Compensation Allocation, under our omnibus agreement, we pay MPC a fixed amount in return for services
provided by our NEOs. The amounts shown in this table were paid to our NEOs by MPC.
All NEOs received base salary increases for 2022 in recognition of their continued strong performance and as part of MPC’s
annual merit program increases to maintain market competitiveness. The higher base salary increase for Mr. Hennigan reflects
the MPC Compensation Committee’s determination to position the CEO’s total direct compensation closer to that of the CEOs of
MPC’s direct peer companies. The higher base salary increases for Messrs. Floerke and Aydt reflect the MPC Compensation
Committee’s determination to bring each NEO closer to the market median for his position. Mr. Aydt’s base salary was further
increased to $800,000 effective September 1, 2022, in recognition of the additional responsibilities he assumed upon his
appointment as MPC’s Executive Vice President, Refining, on that date.
2022 Annual Cash Bonus Program
Our NEOs participated in MPC’s 2022 Annual Cash Bonus (“ACB”) program, which MPC’s Compensation Committee approved
in November 2021, with a performance period of January 1, 2022, through December 31, 2022, as part of their compensation for
the services they provide to MPC and its affiliates, including us. The primary purpose of the 2022 ACB program was to
incentivize and reward eligible employees for executing on MPC’s strategy. MPC determined awards to our NEOs under the ACB
program without input from our Board. Awards under the ACB program for our NEOs were calculated as follows:
Eligible Earnings
×
Bonus Target
×
Performance
=
Final Award
Eligible Earnings generally refers to the NEO’s year-end base salary rate. In an NEO’s year of hire or separation, eligible
earnings is calculated as the sum of base wages paid during the year plus compensation deferred during the year, which has
the effect of prorating the award.
Bonus Target is expressed as a percentage of each NEO’s eligible earnings. MPC’s Compensation Committee approves
bonus target opportunities for our NEOs based on analysis of market-competitive data for MPC’s compensation reference
group, while also taking into consideration each executive’s experience, relative scope of responsibility and potential, other
market data and any other information MPC’s Compensation Committee deems relevant in its discretion.
Performance metrics and levels are established by MPC’s Compensation Committee at the beginning of the performance
period. Once the performance period has ended, MPC’s Compensation Committee reviews and assesses company
performance against the performance metrics and levels, as well as any other factors MPC’s Compensation Committee deems
relevant in its discretion, including each NEO’s organizational and individual performance.
•
•
•
•
There is no guaranteed minimum ACB payout.
Payout results may be above or below target based on actual company and individual performance.
Payouts are capped at 200% of each NEO’s target award.
No upward individual performance adjustments may be made for the CEO; such adjustments for other NEOs are
capped at 15%.

Relative Adjusted EBITDA per Barrel of crude oil throughput is derived from MPC’s Adjusted EBITDA (see below), a non-
GAAP measure, compared to a group of other integrated and downstream companies: Chevron Corporation; Exxon Mobil
Corporation; HF Sinclair Corporation; PBF Energy Inc.; Phillips 66; and Valero Energy Corporation.
Adjusted EBITDA is a non-GAAP performance metric derived from MPC’s consolidated financial statements. It is calculated as
MPC’s earnings before interest and financing costs, interest income, income taxes, depreciation and amortization expense,
adjusted to exclude the effects of impairments, inventory market valuation adjustments, acquisitions and divestitures and
certain other non-cash charges and credits.
Distributable Cash Flow (“DCF”) at MPLX per Unit is a non-GAAP measure reflecting cash flow available to be paid to our
common unitholders, as disclosed in our consolidated financial statements. See Item 7. Management’s Discussion and Analysis
of Financial Condition and Results of Operations – Non-GAAP Financial Information for more information about this measure
and how it is calculated. DCF per unit is determined by dividing DCF by the average unit count during the performance period.
Refining and Corporate Costs are MPC’s externally reported refining operating and corporate costs, excluding costs
associated with MPC’s ACB and other similar employee bonus programs.
Greenhouse Gas (“GHG”) Intensity measures how efficiently MPC operates its facilities and implements a business plan that
promotes a less carbon-intensive future. GHG intensity is based on Scope 1 and Scope 2 GHG emissions divided by the
manufacturing inputs processed at MPC’s refineries and natural gas processing and fractionation plants.
Process Safety Events Score, a new metric for 2022, measures MPC’s ability to identify, understand and control certain
process hazards, taking into account Tier 1 and Tier 2 events, with Tier 1 events multiplied by three to recognize their severity.
Designated Environmental Incidents measures MPC’s environmental performance through tracking Tier 3 and 4 incidents.
Diversity, Equity & Inclusion measures MPC’s effectiveness toward reaching its five-year representation goals with respect to
women and Black, Indigenous and People of Color (“BIPOC”). External hires exclude interns and conditional employees.
Metrics are aspirational in nature and achieving them will at all times be consistent with MPC’s Equal Employment Opportunity
Policy.
128
The performance levels for each metric were established in January 2022 by evaluating factors such as performance achieved in
the prior year(s), anticipated challenges for 2022, and MPC's business plan and overall strategy. MPC’s Compensation
Committee also reviews disclosed peer methodologies of similar metrics when evaluating the rigor of performance goals. The
performance levels were set with threshold levels viewed as likely achievable, target levels viewed as challenging but
achievable, and maximum levels viewed as extremely difficult to achieve.
MPC’s Compensation Committee has sole discretion under the 2022 ACB program to adjust performance metric levels and/or
the final payout percentage to recognize instances where, due to unforeseen circumstances, the performance metrics results are
not entirely indicative of overall company results. MPC’s Compensation Committee made no such adjustments to the 2022
performance metric levels or final payout percentages.
MPC’s Compensation Committee also has discretion under the 2022 ACB program to increase (by no more than 15%) or
decrease payouts to certain of our officers, including our NEOs, based upon its assessment of each individual’s performance and
contributions; provided, that our CEO’s payout cannot be increased pursuant to this discretion. While MPC’s Compensation
Committee determined that our NEOs’ contributions to the successful execution in 2022 of MPC’s business objectives and
enhancement of MPC shareholder value were significant, it concluded that the high achievement of performance metrics under
the 2022 ACB program adequately reflected these contributions and determined to make no individual adjustments.
ACB Payouts for 2022
In February 2023, MPC's Compensation Committee certified the results under the performance metrics for the 2022 ACB
program and, taking into consideration MPC's performance relative to the pre-established metrics and the Committee’s
evaluation of each NEO’s contributions to the key achievements discussed above, awarded the following amounts under the
ACB program to our participating NEOs for 2022:

As noted above in “Compensation Allocation,” under our omnibus agreement, we pay MPC a fixed amount in return for services
provided by our NEOs. The amounts shown in this table will be paid to our NEOs by MPC.
Target percentages for our NEOs remained unchanged from 2021 ACB target percentages. Mr. Aydt’s 2022 ACB target
percentage was increased from 70% to 90% of eligible earnings upon his appointment as MPC’s Executive Vice President,
Refining.
2022 Long-Term Incentive Compensation Program
MPC’s long-term incentive (“LTI”) compensation program is designed to promote achievement of MPC’s and our long-term
business objectives by linking our NEOs’ compensation directly to long-term company and equity performance, further aligning
the interests of our NEOs, MPC’s shareholders and our unitholders.
Under MPC’s 2022 LTI program, MPC’s Compensation Committee awarded our NEOs MPC performance share units (“PSUs”)
and MPC restricted stock units (“RSUs”). Our NEOs also were awarded MPLX phantom units by a committee of our Board
comprised of the independent directors (the “MPLX Committee”) following a recommendation by MPC's Compensation
Committee. For 2022, MPC’s Compensation Committee approved the following LTI mix and annual award amounts for our
NEOs:

MPC PSUs align our NEOs’ long-term compensation interests with MPC’s shareholders’ long-term investment interests by
conditioning payout on the performance of MPC’s PSU Total Shareholder Return (“TSR”) relative to that of MPC’s peers over a
three-year period. Awards vest in full at the end of the performance period.
MPC RSUs promote our NEOs’ ownership of MPC’s common stock, aid in retention and help our NEOs comply with MPC’s
stock ownership guidelines. Awards generally vest ratably over three years.
MPLX Phantom Units promote our NEOs’ ownership of our common units, strengthening alignment between our NEOs’
compensation interests and our unitholders’ investment interests, and help our NEOs comply with our unit ownership
guidelines. Awards generally vest ratably over three years.
To mitigate the effects of share price volatility, the number of awards granted is determined on the basis of the average 30-
calendar day closing price prior to the grant date. Based on a review of competitive market data for each respective role, MPC’s
Compensation Committee made the following increases to each NEO’s 2022 LTI target award compared to 2021: Mr. Hennigan,
9%; Mr. Quaid, 75%; Ms. Gagle, 7%; Mr. Floerke, 18%; Mr. Kaczynski, 0%; Mr. Aydt, 27%. The increase in Mr. Quaid’s 2022 LTI
target award was also a result of his promotion in September 2021 to serve as our Executive Vice President and CFO (from his
previous role as MPC’s Senior Vice President and Controller).
MPC Performance Units/PSUs (2020, 2021 and 2022)
MPC performance units/PSUs pay out based on MPC’s three-year PSU TSR performance relative to the peer group shown in
the following table. MPC’s Compensation Committee chose relative PSU TSR as the metric that most closely aligns the interests
of executives and MPC’s shareholders. Each performance unit granted in 2020 has a target value of $1.00, and the actual
payout can vary from $0.00 to $2.00 (0% to 200% of target) per performance unit. Each PSU granted in 2021 and 2022 has a
target value equal to the MPC common stock average 30-day closing price prior to the grant date, and the actual payout value is
based on company performance (which can range from 0% to 200%) multiplied by MPC’s closing share price on the date MPC’s
Compensation Committee certifies performance. MPC’s relative PSU TSR performance percentile is determined for the specified
measurement periods, with linear interpolation used for results between target levels, as shown below. To provide greater
alignment with MPC’s shareholders, payout under all MPC performance units and PSUs is capped at 100% in measurement
periods when MPC PSU TSR is negative.

and “Outstanding Equity Awards at 2022 Fiscal Year-End” tables below for additional information about these awards.
MPLX Performance Units (discontinued)
MPLX performance units were awarded to our NEOs in 2020 as part of MPC’s LTI compensation program; however, MPLX
performance units are no longer awarded as part of the LTI mix. MPLX performance units awarded in 2020 pay out based 50%
on our total unitholder return (“TUR”) performance relative to a peer group of midstream companies and 50% on distributable
cash flow (“DCF”) attributable to MPLX, measured over a three-year performance cycle. Each MPLX performance unit has a
target value of $1.00, and the actual payout can vary from $0.00 to $2.00 (0% to 200% of target) per performance unit.
Total Unitholder Return (50% of MPLX Performance Unit Payout)

DCF attributable to MPLX is measured for each year of a three-year performance cycle, with each year’s target based on our
annual business plan as approved by our Board. Our DCF metric threshold, target and maximum levels are calculated as 90%,
100% and 105%, respectively, of the annual business plan DCF target. Linear interpolation is used for results between target
levels. In January 2023, the MPLX Committee certified the final relative DCF results for the 2020 MPLX performance units as

OTHER BENEFITS
We do not sponsor any benefit plans, programs or policies such as healthcare, life insurance, income protection or retirement
benefits for our NEOs, and we do not provide perquisites. However, those types of benefits are generally provided to our NEOs
by MPC. MPC makes all determinations with respect to such benefits without input from our Board. MPC bears the full cost of
these programs, and no portion is charged back to us. We have summarized the material elements of these programs below.
Health and Welfare Benefits
Our NEOs are generally eligible to participate in MPC’s market-competitive health and life insurance plans, and long-term and
short-term disability programs.
Retirement Benefits
Retirement benefits provided to our NEOs are designed by MPC to be consistent in value and aligned with benefits offered by
the other companies with which MPC competes for talent. Benefits under MPC’s qualified and nonqualified plans are described
in more detail in “Post-Employment Benefits for 2022” and “2022 Nonqualified Deferred Compensation.”
Severance Benefits
We and MPC maintain change in control plans designed to (i) preserve executives’ economic motivation to consider a business
combination that might result in job loss and (ii) compete effectively in attracting and retaining executives in an industry that
features frequent mergers, acquisitions and divestitures. Our change in control benefits are described further in “Potential
Payments upon Termination or Change in Control.”
Limited Perquisites
Our NEOs receive limited perquisites, which are consistent with those offered by MPC’s peer group companies.
Tax and Financial Planning Services
To offset the expense of obtaining professional tax, estate and financial planning services, MPC generally provides our NEOs
with a $15,000 annual stipend.
Health and Well-being
Under MPC’s enhanced annual physical health program, our senior management, including our NEOs, are eligible for a
comprehensive physical (generally in the form of a one-day appointment), with procedures similar to those available to all other
employees under MPC’s health program.
Use of Corporate Aircraft
The primary use of MPC’s corporate aircraft is for business purposes. MPC’s Board also has authorized Mr. Hennigan’s
personal use of MPC’s corporate aircraft in the interest of his safety and security as its CEO. Certain other executives may be
allowed limited personal use of MPC’s corporate aircraft, and occasionally, spouses or other guests may accompany executive
officers on corporate aircraft when space is available on business-related flights. All such personal use must be authorized by
MPC’s CEO. The cost of any such travel that does not meet the Internal Revenue Service standard for business use is imputed
as income to the executive officer.
Additionally, MPC entered into an aircraft time sharing agreement with Mr. Hennigan, effective January 1, 2021, pursuant to
which he may elect to use MPC’s corporate aircraft for transportation and personal use from time to time on a time sharing
basis and pay MPC for such use pursuant to the terms of the agreement. The agreement was approved by MPC’s Corporate
Governance and Nominating Committee and is reviewed on an annual basis consistent with MPC’s Related Person
Transactions Policy. A copy of the aircraft time sharing agreement was filed as an exhibit to MPC’s Annual Report on Form 10-K
for the year ended December 31, 2020.
Safety and Security
Given the significant public profile of Mr. Hennigan as MPC’s CEO and the publicity given to those in MPC’s industry, MPC’s
Board has authorized certain limited security benefits to Mr. Hennigan, including the maintenance, operation and monitoring of
enhanced security systems. These benefits are monitored by MPC’s Compensation Committee and are taxable income to Mr.
Hennigan.
Reportable values for these benefits and perquisites, based on the incremental costs to MPC, are included in the “All Other
Compensation” column of the “2022 Summary Compensation Table.”
133
COMPENSATION GOVERNANCE
Unit Ownership Guidelines
Our unit ownership guidelines align our executive officers’ long-term interests with those of our unitholders. These guidelines
require the executive officers in the positions shown below to retain MPLX common units with a value at least equal to a target
multiple of their annualized base salary. The targeted multiples vary depending upon the executive’s position and responsibilities:
Position
CEO
MPC Executive Vice President (CEO Direct Report)
MPLX Executive Vice President (CEO Direct Report)
MPC Senior Vice President (CEO Direct Report)
All Other Executives (not reporting to the CEO)
Multiple of Base Salary
2x
1x
0.75x
0.50x
Executives have five years following the establishment of, or an increase in, their applicable unit ownership guideline to achieve
the applicable target multiple. Any executive who does not achieve the unit ownership guideline within this five-year window must
hold all equity we grant until the applicable ownership guideline has been achieved. Our NEOs meet these guidelines.
Prohibition on Hedging and Pledging Our Common Units
Under our policy on trading of securities, none of our directors, officers (including our NEOs) or certain MPC employees
designated under the policy may purchase or sell any financial instrument, including but not limited to put or call options, the
price of which is affected in whole or in part by changes in the price of our securities, unless such financial instrument was issued
by us to such director, officer or covered employee. Further, no director, officer or covered employee may participate in any
hedging transaction related to our securities. This policy ensures that our directors, officers and covered employees bear the full
risk of MPLX common unit ownership.
Recoupment/Clawback Policy
MPC’s ACB and LTI programs provide for recoupment in the case of certain forfeiture events. In addition, our incentive
compensation plans provide that all awards granted thereunder will be subject to clawback or recoupment in the case of certain
forfeiture events. If the SEC or our Audit Committee requires us to prepare a material accounting restatement due to
noncompliance with any financial reporting requirement under applicable securities laws as a result of misconduct, the Audit
Committee may determine that a forfeiture event has occurred based on an assessment of whether an executive officer:
(i) knowingly engaged in misconduct; (ii) was grossly negligent with respect to misconduct; (iii) knowingly failed or was grossly
negligent in failing to prevent misconduct; or (iv) engaged in fraud, embezzlement or other similar misconduct materially harmful
to us.
If it determines that a forfeiture event has occurred, MPC’s Compensation Committee may require reimbursement of any portion
of an executive officer’s bonus from the ACB program that would not have been earned had the forfeiture event not occurred.
Payments made in settlement of performance units may be recouped if the forfeiture event occurred while the executive officer
was employed, or within three years after termination of employment. In addition, the executive’s unexercised and unvested
equity awards would be subject to immediate forfeiture.
These recoupment provisions are in addition to any clawback provisions under Section 304 of the Sarbanes-Oxley Act of 2002,
the Dodd-Frank Wall Street Reform and Consumer Protection Act, NYSE listing standards and other applicable law. In October
2022, the SEC adopted rules requiring the securities exchanges, including the NYSE, to implement listing standards regarding
recovery of incentive compensation, which listing standards may require the Board to update our recoupment provisions. The
Board intends to make any necessary updates to our recoupment provisions following the effectiveness of the new listing
standards.
134
Compensation Risk Assessment
The independent members of our Board regularly review our policies and practices in compensating our service providers
(including both executive officers and non-executives, if any) as they relate to our risk management profile. At the most recent
review of our compensation program, our independent directors concluded that any risks arising from our compensation policies
and practices were not reasonably likely to have a material adverse effect on our financial statements.
Compensation Committee Interlocks and Insider Participation
Because we are a limited partnership, we are not required to have a compensation committee. Compensation matters are
determined by a committee of our Board comprised of the independent directors (the “MPLX Committee”). Compensation
matters for 2022 were determined by Messrs. Helms, Peiffer, Sandman, Semple, Stice and Surma. Ms. Breves did not
participate in compensation decisions for 2022 given the timing of her election to the Board effective November 16, 2022. No
member of the MPLX Committee was at any time during 2022 an officer or employee of MPLX or had any relationship with us
requiring disclosure under Item 404 of Regulation S-K of the Exchange Act. Mr. Semple previously served as our Vice Chairman
from December 2015 until his retirement in October 2016. Mr. Peiffer previously served as our President from 2012 until his
retirement in 2014. See Item 10. Directors, Executive Officers and Corporate Governance - Director Independence for more
information about our independent directors. Our Chairman, President and CEO, Mr. Hennigan, who is also an executive officer
and director of MPC, provides input to the MPLX Committee on compensation matters. During 2022, none of our other executive
officers served on the board of directors or compensation committee of any other entity that has an executive officer serving as a
member of the MPLX Committee or the Board.
COMPENSATION COMMITTEE REPORT
Our independent directors have reviewed and discussed the Compensation Discussion and Analysis for 2022 with management
and, based on such review and discussions, recommended to the Board that the Compensation Discussion and Analysis be
included in this Annual Report on Form 10-K for the year ended December 31, 2022.

Salary shows the actual amount earned during the year. See the CD&A - Base Salary Overview for additional information on
base salaries for 2022.
Bonus reflects a one-time cash amount awarded by MPC’s Compensation Committee to Mr. Aydt in early 2021 in recognition of
the significant responsibilities he assumed beginning in mid-2020 as part of MPC’s organizational restructuring process.
Stock Awards and Option Awards reflect the aggregate grant date fair value of LTIs awarded in the applicable year calculated
in accordance with Financial Accounting Standards Board Accounting Standards Codification 718, Compensation—Stock
Compensation (“FASB ASC Topic 718”). MPC’s Compensation Committee awards LTI to our NEOs based on intended target
values, which reflect established compensation valuation methodologies that differ in some respects from the FASB ASC Topic
718 methodologies reflected in this table. See the CD&A - 2022 Long-Term Incentive Compensation Program for additional
information about the intended target values for the 2022 LTI awards to our NEOs. For assumptions used to determine the
values of these awards as shown in this table, see the “Grant Date Fair Value” note accompanying the “2022 Grants of Plan-
Based Awards” table below, MPC’s Annual Reports on Form 10-K for the years ended December 31, 2022 and 2020 - Item 8.

“Personal Use of Company Aircraft” reflects MPC’s aggregate incremental cost of personal use of corporate aircraft by our
NEOs, their spouses or other guests for 2022. MPC determines the incremental cost for personal use of its aircraft based on the
variable costs to operate the aircraft, but excluding fixed costs that do not change based on usage, such as pilot compensation,
the purchase and lease of aircraft and maintenance not related to travel. MPC believes this method provides a reasonable
estimate of its incremental cost. No income tax assistance or gross-ups are provided for personal use of corporate aircraft. See
the CD&A - Other Benefits beginning on page 133 for additional information regarding personal use of MPC aircraft by our
executives.
The “Tax and Financial Planning” amount shown for Messrs. Quaid and Aydt includes both the $15,000 benefit for 2022 and
$15,000 in respect of expenses each incurred under the tax and financial planning benefit for 2021, reimbursed in 2022.
“Company Contributions to Defined Contribution Plans” reflect MPC’s contributions under its tax-qualified retirement plans and
related nonqualified deferred compensation plans. See “Post-Employment Benefits for 2022” and “2022 Nonqualified Deferred
Compensation” below for more information.
“Other” reflects MPC’s aggregate incremental cost for company-sponsored activities at an off-site Board meeting and the
provision of certain digital services.

Approval Dates. The MPC awards granted on March 1, 2022, were approved by MPC’s Compensation Committee on
January 27, 2022. The MPLX awards granted on March 1, 2022, were approved by the MPLX Committee on February 2, 2022.
MPC RSUs generally vest in equal installments on the first, second and third anniversaries of the grant date. Unvested RSUs
accrue dividend equivalents, which are paid on the scheduled vesting dates. Holders of unvested RSUs do not have voting
rights.
MPC PSUs generally vest following a 36-month performance period and are settled 100% in cash. Unvested PSUs do not
accrue dividends or dividend equivalents and do not have voting rights. The target PSUs shown reflect the target dollar value of
each award divided by the MPC common stock average 30-day closing price prior to the grant date. The threshold, which is the
minimum possible payout, is achieved when the relative PSU TSR percentile achieved is 30th, resulting in a payout percentage
of 50%. Performance below this threshold would result in a payout of 0%. The maximum payout is 200% of target. MPC PSUs
are described in further detail above under “2022 Long-Term Incentive Compensation Program” beginning on page 129.
MPLX Phantom Units generally vest in equal installments on the first, second and third anniversaries of the grant date and are
settled in MPLX common units. Distribution equivalents accrue on the phantom unit awards and are paid on the scheduled
vesting dates. Holders of unvested phantom units have no voting rights.
Grant Date Fair Value reflects the total grant date fair value of each equity award calculated in accordance with FASB ASC
Topic 718. The MPC RSU value is based on the MPC common stock closing price ($75.01) on the grant date, or the prior
business day if the grant date did not fall on a business day. The MPC PSU value is $95.8019 per unit, using a Monte Carlo
valuation model. The MPLX phantom unit value is based on the MPLX common unit closing price ($32.87) on the grant date, or
the prior business day if the grant date did not fall on a business day.

Option Awards reflect MPC stock options, which generally vest in equal installments on the first, second and third anniversaries
of the grant date and expire 10 years after the grant date. The exercise price is generally equal to the closing price of MPC’s
common stock on the grant date, or the prior business day if the grant date did not fall on a business day. Option holders do not
have voting rights or receive dividends on the underlying stock. No stock options have been granted to any NEO since 2020.
Number of Shares or Units of Stock That Have Not Vested reflect the number of unvested MPC RSUs and MPLX phantom
units held on December 31, 2022. MPC RSUs and MPLX phantom units generally vest in equal installments on the first, second

Market Value of Equity Incentive Plan Awards That Have Not Vested reflects the aggregate value of all unvested MPC PSUs
held on December 31, 2022, calculated using the MPC closing common stock price ($116.39) on December 30, 2022, the last
trading day of the year, and an assumed payout of 200% per unit, which is the next higher performance achievement that
exceeds the performance for these awards measured as of December 31, 2022.
Nonforfeitability of Certain Awards. Each NEO (other than Mr. Quaid) is eligible for an Approved Separation, under which their
outstanding 2021 and 2022 MPC RSUs, MPC PSUs and MPLX phantom units would become nonforfeitable should they resign
under certain conditions, as further discussed below under “Potential Payments Upon Termination or Change in Control—
Approved Separation.” Outstanding stock options held by Ms. Gagle and Mr. Aydt are nonforfeitable because each executive is
retirement-eligible, having reached age 50 with at least 10 years of service with MPC. Pursuant to the terms of his promotion to
the CEO role in March 2020, Mr. Hennigan’s outstanding 2020 awards of MPC RSUs and MPLX phantom units became
nonforfeitable on July 1, 2022.
140
When an award becomes nonforfeitable, certain taxes are immediately due. So that the participants do not have an out-of-pocket
expense for these awards that have not yet distributed, the award is instead reduced to cover the tax obligation. These awards
continue to be reflected in the tables above as they remain subject to distribution on their original vesting dates; however, the
portions used to pay any associated taxes have been excluded from these tables and are instead included in the “Option
Exercises and Stock Vested in 2022” table below.

Option Awards: Value Realized on Exercise reflects the actual pre-tax gain realized by our NEOs upon exercise of stock
options, which is the fair market value of the shares at exercise less the per share grant price.
Stock/Unit Awards: Number of Shares/Units Acquired on Vesting includes the following numbers of shares/units used to pay
the taxes associated with the vesting of certain awards held by the NEOs as discussed further under “Outstanding Equity Awards
at 2022 Fiscal Year-End”: Mr. Hennigan, 6,558 MPC RSUs/restricted stock, 5,813 MPLX phantom units; Ms. Gagle, 256 MPC
RSUs/restricted stock, 606 MPLX phantom units; Mr. Floerke, 135 MPC RSUs/restricted stock, 320 MPLX phantom units; Mr.

POST-EMPLOYMENT BENEFITS FOR 2022
2022 Pension Benefits
MPC provides tax-qualified retirement benefits to its employees, including our NEOs, under the MPC Retirement Plan. MPC also
sponsors the MPC Excess Benefit Plan, an unfunded nonqualified deferred compensation plan made available to a select group
of management or highly compensated employees, including our NEOs. The following table reflects the actuarial present value
of accumulated benefits payable to each of our NEOs under the MPC Retirement Plan and the defined benefit portion of the
MPC Excess Benefit Plan as of December 31, 2022. These values have been determined using actuarial assumptions consistent
with those used in MPC’s financial statements.

Number of Years Credited Service shows the number of years the NEO has participated in each plan. Plan participation
service used to calculate each participant’s benefit under the MPC Retirement Plan legacy benefit formula (applicable to Ms.
Gagle and Mr. Aydt only) was frozen as of December 31, 2009.
Present Value of Accumulated Benefit Present Value of Accumulated Benefit for the legacy benefit under the MPC Retirement
Plan was calculated assuming a 85% lump sum election rate with a lump sum interest rate between 0.25% and 1.25% (based on
anticipated year of retirement) and the RP-2000 mortality table, and a 15% annuity election rate with a discount rate of 5.10%
and the Pri-2012 mortality table with generational mortality improvements in accordance with Scale MP-2021, both calculated
assuming retirement at age 62 (or current age, if later). See "MPC Retirement Plan" below for more detail on the legacy benefit
formula.
The present value of accumulated benefits for the cash balance benefits under the MPC Retirement Plan was calculated
assuming retirement at age 62 (or current age, if later), a discount rate of 5.10%, a cash balance interest credit rating of 3.0% in
2022, 3.57% in 2023 and 3.97% in 2024 and beyond, and the Pri-2012 mortality table with generational mortality improvements
in accordance with Scale MP-2021. See "MPC Retirement Plan" below for more detail on the cash balance benefit formula under
each plan.
MPC Retirement Plan
MPC’s employees, including our NEOs, participate in the MPC Retirement Plan, which is a tax-qualified defined benefit
retirement plan primarily designed to provide participants with income after retirement. Participants in the plan become fully
vested upon completing three years of vesting service. Normal retirement age under the plan is 65. The plan has both a “legacy”
retirement benefit and a “cash balance” retirement benefit.
Legacy Benefit
Prior to 2010, the monthly benefit was determined under the following legacy benefit formula:
1.6% ×

This formula was amended effective January 1, 2010, to cease future accruals of additional participation years, and as applied to
eligible NEOs, cease further compensation updates. No more than 37.5 participation years may be recognized under the
formula. Eligible earnings include, but are not limited to, pay for hours worked, pay for allowed hours, military leave allowance,
commissions, bonuses and elective deferrals to the MPC Thrift Plan. Age continues to be updated under the formula.
Under the legacy retirement benefit, a vested participant who is at least age 62 may retire prior to age 65 and receive an
unreduced benefit. Ms. Gagle and Mr. Aydt each have vested legacy retirement benefits under the plan that remain subject to
reduction as neither executive has reached age 62. Available benefits include various annuity options and a lump sum
distribution option. Participants are eligible for early retirement upon reaching age 50 and completing 10 years of vesting service.
If an employee retires between the ages of 50 and 62 with sufficient vesting service, the amount of benefit under the legacy
benefit formula is reduced as follows:

The plan was amended effective August 31, 2022, to allow an active participant who has attained age 59.5 to elect to take an in-
service distribution of their legacy retirement benefit on or after December 1, 2022. As of December 31, 2022, Mr. Aydt was the
only NEO eligible to elect an in-service distribution. Mr. Aydt made such an election in 2022 with regard to his legacy retirement
benefit; however, the distribution was made after December 31, 2022.
Cash Balance Benefit
Starting in 2010, benefit accruals are determined under the following cash balance formula:
MPC Cash Balance Formula
Annual
Pay Credit
Percentage
Compensation ×
+ Account Balance ×
Interest Credit Rate
Cash Balance Annual Benefit
ð Participants receive pay credit percentages based on the sum of
their age and cash balance service:
Participant
Points
Pay Credit
Percentage
Fewer than 50
Points
7%
50-69 Points
9%
70 Points or
More
11%
Annual compensation is limited to $305,000 for 2022 and generally includes wages and salary for time worked, with certain
exclusions. Under the cash balance retirement benefit, a vested participant may retire at any age prior to 65 and receive an
unreduced benefit. Each NEO has a vested cash balance retirement benefit under the plan that is not subject to reduction upon
retirement. Under the cash balance formula, plan participants receive pay credits based on age and cash balance service. For
2022, Ms. Gagle and Mr. Aydt received pay credits equal to 11% of compensation, and Messrs. Hennigan, Quaid, Floerke and
Kaczynski received pay credits equal to 9% of compensation. There are no early retirement subsidies under the cash balance
formula.
MPC Excess Benefit Plan (Defined Benefit Portion)
The MPC Excess Benefit Plan is an unfunded nonqualified deferred compensation plan maintained for the benefit of a select
group of management or highly compensated employees. This plan generally provides benefits that participants, including our
NEOs, would have otherwise received under the tax-qualified MPC Retirement Plan were it not for Internal Revenue Code
limitations. For our NEOs, eligible earnings under the plan include the compensation items shown above for the MPC Retirement
Plan, but without regard to any Internal Revenue Code limit, as well as any salary and bonus amounts deferred by the NEO
under the MPC Executive Deferred Compensation Plan.
With respect to Ms. Gagle and Mr. Aydt, who have frozen legacy-type benefits under the plan, eligible earnings for the legacy-
type portion were determined using each NEO’s highest consecutive 36-month compensation (exclusive of bonuses) and three
highest bonuses earned over the 10-year period up to December 31, 2012. None of our other NEOs have a legacy-type benefit
under the plan.
Due to the structure of the frozen MPC legacy benefit formula under the MPC Retirement Plan, the age-related benefit
conversion factors used to calculate lump sum benefits under the frozen legacy benefit formula result in a year-to-year decrease
in the lump sum benefit for participants generally beginning on or after the age of 59. As a result, if participants choose to
continue their employment with MPC after they reach age 59, their lump sum benefit may decline year to year.
The MPC Excess Benefit Plan permits MPC’s Compensation Committee, on a discretionary basis, to extend a lump sum
retirement benefit supplement (“Service Benefit”) to individual officers of MPC who have a frozen legacy-type benefit under the
plan to offset the age-related erosion (if any) of the frozen legacy-type benefit from age 62 until such officer’s actual retirement
date or date of death. An officer must be vested under the MPC Retirement Plan to qualify for the Service Benefit. Each of Ms.
143
Gagle and Mr. Aydt have a frozen legacy-type benefit under the plan; however, MPC’s Compensation Committee has not
extended eligibility for this benefit to either of them at this time.
Tax-Qualified Defined Contribution Retirement Plan
The MPC Thrift Plan is a tax-qualified, defined contribution retirement plan. In general, all of MPC’s employees, including our
NEOs, are immediately eligible to participate in the plan. The purpose of the plan is to assist employees in maintaining a steady
program of savings to supplement their retirement income and to meet other financial needs.
The MPC Thrift Plan allows eligible employees, such as our NEOs, to make elective deferral contributions to their plan accounts
on a pre-tax or after-tax “Roth” basis from 1% to a maximum of 75% of their plan-considered gross pay, with such gross pay
limited to the applicable Internal Revenue Code annual compensation limit ($305,000 for 2022). Eligible employees who are
“highly compensated employees” as determined under the Internal Revenue Code, such as our NEOs, may additionally make
after-tax contributions to their plan accounts from 1% to 6% of their plan-considered gross pay limited to the applicable Internal
Revenue Code annual compensation limit ($305,000 for 2022). Employer matching contributions are made on such elective
deferrals and after-tax contributions at a rate of 117% up to a maximum of 6% of an employee’s plan-considered gross pay. All
employee elective deferrals and after-tax contributions, and all employer matching contributions made, are fully vested.

MPC Excess Benefit Plan (Defined Contribution Portion)
The MPC Excess Benefit Plan is an unfunded nonqualified deferred compensation plan maintained for the benefit of a select
group of management or highly compensated employees. Participants receive employer matching contributions equal to the
amount they would have otherwise received under the tax-qualified MPC Thrift Plan were it not for Internal Revenue Code
limitations.
Defined contribution accruals in the MPC Excess Benefit Plan are credited with interest equal to that paid in a specified
investment option of the MPC Thrift Plan, which was 1.36% for the year ended December 31, 2022. All plan distributions are paid
in a lump sum following the participant’s separation from service. In general, our NEOs no longer actively participate in the
defined contribution portion of the MPC Excess Benefit Plan, and all subsequent year nonqualified employer matching
contributions for NEOs now accrue under the MPC Executive Deferred Compensation Plan.
MPC Deferred Compensation Plan
The MPC Deferred Compensation Plan is an unfunded nonqualified deferred compensation plan maintained for the benefit of a
select group of management or highly compensated employees, including our NEOs. Effective January 1, 2021, the plan was
generally frozen with respect to any further MPC participant salary and bonus deferrals and additional company contribution
credited amounts. Prior to the plan’s freeze, participants could defer up to 20% of their salary and bonus each year in a tax-
advantaged manner, with irrevocable deferral elections made in December of each year for amounts to be earned in the
following year. The plan credited matching contributions on a participant’s deferrals equal to the match under the MPC Thrift Plan
(117% as in effect prior to the plan’s freeze) plus an amount equal to the matching contributions the participant would have
received, but for Internal Revenue Code limitations and compensation limits, under the MPC Thrift Plan. Participants are fully
vested in all amounts credited on their behalf under the plan. Participants may make notional investments of their notional plan
accounts from among certain investment options offered under the MPC Thrift Plan, and participants’ notional plan accounts are
credited with notional earnings and losses based on the result of those investment elections. Participants generally receive
payment of their plan benefits in a lump sum following separation from service.
MPC Executive Deferred Compensation Plan
The MPC Executive Deferred Compensation Plan is an unfunded nonqualified deferred compensation plan maintained for the
benefit of a select group of management or highly compensated employees, including our NEOs. Participants may defer 5% to
20% (in whole percentage increments) of their base salary and annual bonus each year in a tax-advantaged manner. Deferral
elections are made each December for amounts to be earned in the following year and are irrevocable. The plan credits
matching contributions on a participant’s deferrals equal to the match under the MPC Thrift Plan plus an amount equal to the
matching contributions the participant would have received, but for Internal Revenue Code limitations and compensation limits,
under the MPC Thrift Plan. Participants are fully vested in their deferrals and matching contributions. Participants may make
notional investments of their notional plan accounts from among certain investment options offered under the MPC Thrift Plan,
and participants’ notional plan accounts are credited with notional earnings and losses based on the result of those investment
elections. Participants may elect to receive payment of their plan benefits in a lump sum or in annual installments over two to five
years on or beginning on a specified date while in service or following separation from service.
Section 409A Compliance
All of MPC’s nonqualified deferred compensation plans in which our NEOs participate are intended to comply with, or be exempt
from, Section 409A of the Internal Revenue Code. As a result, distribution of amounts subject to Section 409A may be delayed
for six months following retirement or other separation from service where the participant is considered a “specified employee”
for purposes of Section 409A. All of our NEOs are “specified employees” for purposes of Section 409A.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL
The following table provides information regarding the amount of compensation payable to our NEOs as a direct result of each
specified hypothetical termination scenario, assuming that the applicable termination event occurred on December 31, 2022,
based on the plans and agreements in place on that date. The actual payments to which an NEO would be entitled may only be
determined based upon the actual occurrence and circumstances surrounding the termination.

Severance. Under the MPLX LP Executive Change in Control Severance Benefits Plan, as further described below, cash
severance will only be paid upon a change in control if the NEO experiences a Qualified Termination (as defined below). If the
Qualified Termination occurs within three years prior to the date the NEO reaches age 65, the NEO’s benefit will be limited to a
pro rata portion of the benefit. Mr. Hennigan’s benefit has been reduced as he is within three years of reaching age 65.
Pension Benefits for our NEOs are reflected in the “2022 Pension Benefits” table above. Amounts in this potential payments
table represent additional pension benefits attributable solely to the legacy benefit formula in the MPC Retirement Plan, further
described beginning on page 142. The incremental retirement benefits included in these amounts were calculated using the
following assumptions: individual life expectancies using the RP2000 Combined Healthy Table weighted 75% male and 25%
female; a discount rate of 0.00% for NEOs who are retirement eligible (taking into account the additional three years of age and
service credit) and 0.00% for NEOs who are not retirement eligible; the current lump-sum interest rate for the relevant plans; and
147
a lump-sum form of benefit. Only Ms. Gagle and Mr. Aydt are eligible for this enhanced benefit under the legacy benefit formula
as it is applicable only to individuals who participated in the MPC Retirement Plan prior to 2010.
Vested Equity (MPC Stock Options, MPC RSUs, MPC PSUs and MPLX Phantom Units)
The amounts in this table reflect the value of equity that would vest on an accelerated basis as a direct result of each applicable
scenario. Each of our NEOs (other than Mr. Quaid) holds certain awards that have become nonforfeitable by their terms. Awards
no longer subject to forfeiture irrespective of the termination scenario are not included in this table. See the tables and
accompanying narrative under “Outstanding Equity Awards at 2022 Fiscal Year-End” for more information about these
nonforfeitable awards and their respective vesting dates.
Vesting of MPC stock options is accelerated upon retirement or a change in control with a Qualified Termination. Amounts shown
reflect the value realized if accelerated stock options were exercised on December 30, 2022, taking into account the spread (if
any) between the options’ exercise prices and the closing price of MPC common stock ($116.39) on December 30, 2022, the last
trading day of the year.
Vesting of MPC RSUs and MPLX phantom units is accelerated upon a death or change in control with a Qualified Termination.
Amounts shown reflect the value realized if MPC RSUs and MPLX phantom unit awards vested on December 30, 2022, based
on the closing price of MPC common stock ($116.39) and MPLX common units ($32.84) on December 30, 2022, the last trading
day of the year. In the event of Mr. Floerke’s termination of employment for any reason other than for cause, the MPLX phantom
units he received as part of his retention award in 2015 will become payable.
In the event of death or a change in control and a Qualified Termination, unvested MPC PSUs will vest and be paid out based on
actual performance for the period from the grant date to the change in control date, and target performance for the period from
the change in control date to the end of the performance cycle. Amounts shown reflect the amounts payable in each scenario,
calculated using the target value ($116.39, the closing price of MPC common stock on December 30, 2022, the last trading day
of the year) for each MPC PSU.
Other Benefits includes 36 months of continued health, dental and life insurance coverage. In the event of death, life insurance
would be paid out to the estates of our NEOs in the following amounts: Mr. Hennigan, $3.0 million; Mr. Quaid, $1.2 million; Ms.
Gagle, $1.4 million; Mr. Floerke, $1.1 million; Mr. Kaczynski, $0.9 million; Mr. Aydt, $1.0 million.
Voluntary Termination
Resignation
Upon an NEO’s voluntary resignation, LTI awards still subject to forfeiture, including vested but unexercised stock options,
generally are forfeited unless provided otherwise in the applicable award agreement. As discussed above under “Outstanding
Equity Awards at 2022 Fiscal Year-End,” certain awards held by our NEOs have become nonforfeitable by their terms and thus
would not be forfeited in the event of resignation.
Retirement
Our employees generally are eligible for retirement once they reach age 50 and have at least 10 years of vesting service with
MPC or its subsidiaries. As of December 31, 2022, Ms. Gagle and Mr. Aydt were retirement eligible. Retirement-eligible NEOs
who serve less than a full year in their year of retirement are eligible for a target bonus under the ACB program, prorated based
on their eligible earnings for the performance period. Upon retirement, our NEOs are entitled to receive their vested benefits that
have accrued under our employee and qualified retirement and nonqualified deferred compensation plans. For more information
about our retirement and deferred compensation programs, see “2022 Pension Benefits” and “2022 Nonqualified Deferred
Compensation.”
In addition, upon retirement, our NEOs’ unvested stock options become exercisable according to the grant terms and expire
upon the earlier of five years following retirement and the existing expiration date applicable to each such option. MPC RSUs and
MPLX phantom units still subject to forfeiture generally are forfeited upon retirement (except in the case of mandatory retirement
at age 65, when they vest in full, or an Approved Separation as discussed below). MPC PSUs vest in the case of mandatory
retirement, death, Qualified Termination or Approved Separation. Payout will occur following the full performance cycle based on
its certified results, except in the instance of death, which would be paid immediately at target.
Approved Separation
Under the terms of MPC’s and our 2021 and 2022 LTI award agreements, our NEOs generally are eligible for an Approved
Separation once they reach age 55 and have at least five years of employment with MPC or its subsidiaries. As of December 31,
2022, each of our NEOs (other than Mr. Quaid) was eligible for an Approved Separation. Under an Approved Separation
scenario, 2021 and 2022 MPC RSUs, MPC PSUs and MPLX phantom units would become nonforfeitable upon an eligible NEO’s
resignation provided they had held such awards at least six months and provided notice at least 180 days prior to such
resignation. MPC’s Compensation Committee may, in its sole discretion, waive this notice requirement.
148
Involuntary Termination Without Cause or With Good Reason
Neither MPC nor we generally enter into employment or severance agreements with our NEOs. An NEO whose employment is
terminated by us without cause, or who terminates employment with good reason, is eligible for the same termination allowance
plan available to all other MPC employees, which would pay (i) an amount between eight and 62 weeks of salary based either on
service or salary level, and (ii) an additional amount equal to the NEO’s target bonus under MPC’s ACB program prorated for
service up to the termination date. Upon involuntary termination of an NEO without cause, or termination with good reason,
vested stock options generally are exercisable for 90 days following termination.
Involuntary Termination for Cause
Upon an NEO’s involuntary termination for cause, unvested LTI awards, including vested but unexercised stock options,
generally are forfeited unless provided otherwise in the applicable award agreement.
Death
In the event of death, our NEOs (or their beneficiaries) are entitled to the vested benefits they have accrued under MPC’s
employee benefit programs. In the event of the death of an NEO during the ACB performance period, unless otherwise
determined by MPC’s Compensation Committee, a target bonus will be paid. LTI awards immediately vest in full upon death, with
MPC PSUs vesting at the target level.
Change in Control
Our NEOs participate in two change in control severance plans: the MPC Amended and Restated Executive Change in Control
Severance Benefits Plan (“MPC CIC Plan”) and the MPLX Executive Change in Control Severance Benefits Plan (“MPLX CIC
Plan”). These change in control plans were designed to (i) preserve executives’ economic motivation to consider a business
combination that might result in job loss and (ii) compete effectively in attracting and retaining executives in an industry that
features frequent mergers, acquisitions and divestitures.
Benefits under each plan are payable only upon a change in control and a Qualified Termination. The table below shows the
benefits for which our NEOs would be eligible upon a change in control of MPC or MPLX and a Qualified Termination with the
applicable entity. In the event of a change in control and Qualified Termination under both plans, our NEOs would receive
benefits under only one plan – whichever provides the greater benefits at that time.
A “Qualified Termination” generally occurs when an NEO’s employment with our affiliates and us ends in connection with, or
within two years after, a change in control. Exceptions include:
● Separation due to death or disability
● Termination for cause
● Termination after age 65
● Voluntary termination without good reason (“good reason” includes a
material reduction in roles, responsibilities, pay or benefits, or being
required to relocate more than 50 miles from one’s current location)
CHANGE IN CONTROL OF MPC
CHANGE IN CONTROL OF MPLX
A lump sum cash payment of up to three times the sum of the NEO’s current annualized base salary plus three times the
highest bonus paid in the three years before the termination or change in control.
Life and health insurance benefits for up to 36 months after
termination at the lesser of the current cost or the active
employee cost.
Life and health insurance benefits for up to 36 months after
termination at the active employee cost.
An additional three years of service credit and age credit for purposes of retiree health and life insurance benefits.
A lump sum cash payment equal to the actuarial equivalent of the difference between amounts receivable by the NEO under
the final average pay formula in our pension plans and those payable if: (i) the NEO had an additional three years of
participation service credit; (ii) the NEO’s final average pay were the higher of the NEO’s salary at the time of the change in
control event or Qualified Termination plus the NEO’s highest annual bonus from the preceding three years (for purposes of
determining early retirement commencement factors, the NEO is credited with three additional years of vesting service and
three additional years of age); and (iii) the NEO’s pension had been fully vested.
A lump sum cash payment equal to the difference between amounts receivable under our tax-qualified and nonqualified defined
contribution type retirement and deferred compensation plans and amounts that would have been received if the NEO’s defined
contribution plan account had been fully vested.
Accelerated vesting of all outstanding MPC LTI awards.
Accelerated vesting of all outstanding MPLX LTI awards.
149
The MPLX CIC Plan also provides that NEOs who do not incur a Qualified Termination but separate from service with MPLX as a
result of an MPLX change in control (in other words, where the NEO remains employed with MPC but no longer provides
services to MPLX) will become fully vested in all outstanding MPLX LTI awards. NEOs who receive an offer for comparable
employment from an acquirer or successor entity in an MPLX change in control will not be eligible to receive benefits under the
MPLX CIC Plan.
CEO PAY RATIO
We do not determine the total compensation of our CEO or of any of the other personnel responsible for managing and operating
our business, all of whom are employed by MPC and not by our general partner or us. Because we do not directly employ any
employees and do not determine or pay total compensation to the employees of MPC who manage and operate our business,
we do not have a median employee whose total compensation can be compared to the total compensation of our CEO.
DIRECTOR COMPENSATION
Officers or employees of our general partner or MPC who also serve as our directors do not receive additional compensation for
their service as our director. Directors who are not officers or employees of our general partner or MPC receive compensation as
“non-employee directors.”

to certain tax-exempt educational institutions each year.

Fees Earned or Paid in Cash reflect cash retainers earned for Board service in 2022.
Unit Awards reflect the aggregate grant date fair value of phantom units, calculated in accordance with financial accounting
standards. Non-employee directors generally received grants each quarter of phantom units valued at $27,500 based on the
closing price of our common units on each grant date. The aggregate number of phantom units in respect of Board service
outstanding for each non-employee director as of December 31, 2022 is: Ms. Breves, 405; Mr. Helms, 44,778; Mr. Peiffer,
40,427; Mr. Sandman, 44,778; Mr. Semple, 32,148; Mr. Stice, 25,884; Mr. Surma, 44,778.
All Other Compensation reflects contributions made to educational institutions under MPC’s matching gifts program, as
described above. This program is subject to an annual limit of $10,000; however, the actual amount paid out on behalf of a
director may exceed $10,000 in a given year due to end-of-year processing delays.

Item 13. Certain Relationships and Related Transactions, and Director Independence
Policy and Procedures with Respect to Related Person Transactions
The Board has adopted a formal written related person transactions policy establishing procedures for the notification, review,
approval, ratification and disclosure of related person transactions. Under the policy, a “related person” includes any director,
nominee for director, executive officer, or a known beneficial holder of more than five percent of any class of our voting securities
(other than MPC or its affiliates) or any immediate family member of a director, nominee for director, executive officer or more
than five percent owner. This procedure applies to any transaction, arrangement or relationship and any series of similar
transactions, arrangements or relationships in which (i) we are a participant, (ii) the amount involved exceeds $120,000, and (iii)
a related person has a direct or indirect material interest.
The Board has provided its standing pre-approval for the following transactions, arrangements and relationships:
•
•
•
•
Payment of compensation to an executive officer or director of our general partner if the compensation is otherwise required
to be disclosed in our filings with the SEC;
Any transaction where the related person’s interest arises solely from the ownership of securities;
Any ongoing employment relationship provided that such employment relationship will be subject to initial review and
approval; and
Any transaction between any of our subsidiaries and us, on the one hand, and our general partner or any of its affiliates, on
the other hand; provided, however, that such transaction is approved consistent with our Partnership Agreement.
Any related person transaction identified prior to its consummation must be approved in advance by the Board. If the related
person transaction is identified after it commences, it will be promptly submitted to the Board or the Chairman for ratification,
amendment or rescission. If the transaction has been completed, the Board or the Chairman will evaluate the transaction to
determine if rescission is appropriate. Transactions entered into prior to the closing of our initial public offering, when this policy
was adopted, were approved by the Board apart from the policy.
In determining whether to approve or ratify a related person transaction, the Board or the Chairman will consider all relevant facts
and circumstances, including but not limited to:
•
•
•
•
The benefits to us, including the business justification;
If the related person is a director or an immediate family member of a director, the impact on the director’s independence;
The availability of other sources for comparable products or services;
The terms of the transaction and the terms available to unrelated third parties or to employees generally; and
• Whether the transaction is consistent with our Code of Business Conduct.
This policy is available on the “Corporate Governance” page of our website at www.mplx.com/Investors/Corporate_Governance/
Policies_and_Guidelines/.

Our Relationship with MPC
As of December 31, 2022, MPC owned through its affiliates 647,415,452 of our common units, representing approximately 65%
of our common units outstanding, and 100% of MPLX GP, our general partner. MPLX GP manages our operations and activities
through its officers and directors. In addition, various of our officers and directors also serve as officers and/or directors of MPC.
Accordingly, we view transactions between MPC and us as related party transactions and have provided the following
disclosures with respect to such transactions during 2022. Unless the context otherwise requires, references in the following
discussion to “we” or “us” refer to our affiliates and us.
Distributions and Reimbursements to MPC
Pursuant to our Partnership Agreement, we make cash distributions to our unitholders, including MPC. During 2022, we
distributed to MPC approximately $1,871 million with respect to the common units it holds.
Under our Partnership Agreement, we reimburse MPLX GP and its affiliates, including MPC, for all costs and expenses incurred
on our behalf. The amount we reimbursed in 2022 was $2 million.
Transactions and Commercial and Other Agreements with MPC
We have multiple long-term, fee-based transportation and storage services agreements, as well as a variety of operating
services agreements, management services agreements, licensing agreements, employee services agreements, omnibus
agreements, a keep whole commodity agreement and a loan agreement with MPC and its consolidated subsidiaries. See Item 1.
Business – Our L&S Contracts with MPC and Third Parties, Item 1. Business – Our G&P Contracts with MPC and Third Parties,
and Item 8. Financial Statements and Supplementary Data – Note 6, for information regarding related party activities with MPC.

Pre-Approval of Audit Services
Among other things, our Pre-Approval of Audit, Audit-Related, Tax and Permissible Non-Audit Services Policy sets forth the
procedure for the Audit Committee to pre-approve all audit, audit-related, tax and permissible non-audit services, other than as
provided under a de minimis exception. Under the policy, the Audit Committee may pre-approve any services to be performed by
our independent auditor up to twelve months in advance and may approve in advance services by specific categories pursuant to
a forecasted budget. Annually, the executive vice president and chief financial officer of our general partner will present a
forecast of audit, audit-related, tax and permissible non-audit services for the ensuing fiscal year to the Audit Committee for
approval in advance. The executive vice president and chief financial officer of our general partner, in coordination with the
independent auditor, will provide an updated budget to the Audit Committee, as needed, throughout the ensuing fiscal year.
For unbudgeted items, the Audit Committee has delegated pre-approval authority of up to $250,000 to the Chair of the Audit
Committee; such items are reported to the full Audit Committee at its next scheduled meeting.
In 2022 and 2021, the Audit Committee pre-approved all audit, audit-related, tax and permissible non-audit services pursuant to
this policy and did not use the de minimis exception.

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.
