Merger Transactions

Take Private Proposal

On August 4, 2021, the board of directors of BP Midstream Partners GP LLC, a
Delaware limited liability company and the general partner of our Partnership
(the "General Partner") received a non-binding preliminary proposal letter from
BP Pipelines, through its wholly-owned subsidiary BP Midstream Partners Holdings
LLC, to acquire all of our issued and outstanding common units not already owned
by BP Pipelines or its affiliates at a to-be-determined fixed exchange ratio.

Merger Agreement



On December 19, 2021, BP Midstream Partners LP, BP Midstream Partners GP LLC, BP
p.l.c., BP Midstream Partners Holdings LLC, ("Holdings"), and BP Midstream RTMS
LLC ("Merger Sub"), entered into an Agreement and Plan of Merger (the "Merger
Agreement"), pursuant to which Merger Sub will merge with and into the
Partnership, with the Partnership surviving as an indirect, wholly owned
subsidiary of BP (the "Merger").

Under the terms of the Merger Agreement, at the effective time of the Merger,
(i) each outstanding common unit other than those owned by BP and its
subsidiaries (each, a "Public Common Unit") will be converted into the right to
receive 0.575 BP American Depositary Shares ("ADSs") each representing six
ordinary shares of BP (the "Merger Consideration" and such ratio, the "Exchange
Ratio"). In connection with the Merger, (i) any partnership interests that are
owned by the Partnership or any of the Partnership's subsidiaries will be
cancelled; and (ii) the common units owned by Parent and its subsidiaries, the
General Partner's general partner interest and the incentive distribution rights
in the Partnership will not be cancelled, will not be converted into the right
to receive Merger Consideration and will remain outstanding following the
Merger.

The Partnership has entered into a Support Agreement, dated as of December 19,
2021 (the "Support Agreement"), with Holdings, pursuant to which Holdings has
irrevocably and unconditionally agreed to deliver a written consent covering all
of the Partnership Common Units beneficially owned by it in favor of the Merger,
the approval of the Merger Agreement and the transactions contemplated by the
Merger Agreement and any other matter necessary or desirable for the
consummation of the transactions contemplated by the Merger Agreement (the
"Support Written Consent"), within two business days following the effectiveness
of the registration statement.

Registration Statement

A registration statement on Form F-4 registering 165,164,448 shares of BP Ordinary Shares, which will be issued in the form of American depositary shares, each representing six BP Ordinary Shares ("BP ADSs"), to effectuate such acquisition of Public


                                       57
--------------------------------------------------------------------------------

Common Units was filed by BP on January 31, 2022, as amended (Registration No.
333-262425) (the "Registration Statement") and declared effective by the
Securities and Exchange Commission (the "SEC") on March 4, 2022. Completion of
the transaction is expected in the second quarter, subject to customary closing
conditions. Upon completion, the Partnership Common Units will cease to be
listed on the New York Stock Exchange ("NYSE") and will be subsequently
deregistered under the Securities Exchange Act of 1934, as amended. For more
information, see the risks and uncertainties discussed in Part I, Item 1A. Risk
Factors-Risks Related to the Merger in this Annual Report.

Business Environment, Market Conditions and Outlook



The impacts to the energy industry from the decline and subsequent volatility in
demand for petroleum and petroleum-based products resulting from the response to
the global outbreak of COVID-19 have been unprecedented. Management continues to
monitor the uneven macro environment. For risks associated with COVID-19,
hurricanes and other factors, refer to "  Item 1A. Risk Factors  " in this
Annual Report.

In the year ended December 31, 2021, we experienced a reduction in volumes on
our onshore pipelines compared to 2020. On Diamondback and River Rouge, we
experienced lower throughput due to reduced demand from shippers. With respect
to BP2, there was a slight increase in volumes as a result of lower
apportionment during the fourth quarter on the Enbridge mainline and refinery
feedstock optimization. The impacts of this reduction in volumes are partially
offset by $4.0 million of deficiency revenue recorded under our MVCs.

Weather Impacts and Hurricane Ida



The Atlantic hurricane season this year was the third-most active on record in
terms of the number of storms in a single season. During the third and fourth
quarters of 2021, the operations of our Offshore Pipelines were disrupted by
multiple weather events in the Gulf of Mexico. Such events have been material,
and are reasonably likely in the future to cause a serious business disruption
or serious damage to our pipeline systems which could affect such systems'
ability to transport crude oil and natural gas.

In late August 2021, Hurricane Ida formed and threatened catastrophic damage to
the U.S. Gulf Coast along its path. In response, producers in the Gulf of
Mexico, including BP, suspended production at platforms and evacuated offshore
workers. Additionally, operators performed impact assessments when it was safe
to do so. Caesar, Cleopatra, Proteus and Endymion were able to return to normal
operating service at different points in September 2021.

While no damage was directly incurred by any of the assets held by the Mars
joint venture that we have an interest in, damage to the West Delta-143 facility
was discovered after a comprehensive damage assessment and resulted in the
facility remaining offline for repairs. On November 5, 2021, the West Delta-143
offshore facilities safely re-started operations. With the facilities now
operational, the Mars Oil Pipeline resumed normal operations.

Shippers provided notice that, effective as of August 29, 2021, Hurricane Ida
constituted an event of force majeure under their current contracts, which has
since been cancelled consistent with the resumption of normal operations of the
Mars Oil Pipeline. We estimate that this outage caused a reduction of
approximately $8 million to $10 million to our cash available for distribution
for the year ended December 31, 2021 relative to our financial outlook. For more
information, refer to our risk factor titled "Hurricanes and other severe
weather conditions, natural disasters or other adverse events or conditions
could damage our pipeline systems or disrupt the operations of our customers,
which could adversely affect our operations and financial condition."

COVID-19



Uncertainties related to COVID-19 continue to affect the oil and gas industry,
including the possibility of renewed restrictions on various commercial, social,
and economic activities, thereby impacting the demand for crude oil, natural
gas, and refined products.

To limit the impact of COVID-19, BP Pipelines, as operator of our assets under
the omnibus agreement, and our other customers, as well as third-party operators
of our pipelines, have implemented various protocols for both onshore and
offshore personnel; however, these protocols may not prove to be successful.
There is risk of decreased volumes with respect to our offshore operations if
operators take actions to reduce operations in response to demand volatility or
the inability to control COVID-19 infections on platforms and are required to
shut-in. Additionally, we expect the shippers on our offshore pipelines to
continue to find buyers for their production; however, they may not be
successful.

                                       58
--------------------------------------------------------------------------------

BP Pipelines and the third-party operators of our assets have taken steps and
continue to actively work to ensure appropriate practices are adopted for
continued functioning of our assets as well as mitigation strategies for any
office or worksite where COVID-19 may be detected. However, there is no
certainty that the measures we take will be ultimately sufficient.

Climate Change



In the bp Energy Outlook 2020, which is not incorporated into and does not form
a part of this Annual Report or any other filings we make with the SEC, our
Parent describes the potential implications of climate change and the energy
transition on both primary energy demand and the energy system over the next 30
years, through three long-term scenarios.

These scenarios are complex and subject to substantial uncertainty due to the
many factors and assumptions involved in them, which are not detailed in this
Form 10-K. BP2, River Rouge and Diamondback are operated by BP Pipelines
personnel under the omnibus agreement. Any judgments and assumptions taken by
our Parent could potentially result in adverse impacts on demand for our
services, for which we cannot predict the speed or intensity of any such impacts
at this time. For more information, see our risk factor "Increasing attention to
ESG matters and conservation matters may impact our business."

How We Generate Revenue

Onshore Assets

We generate revenue on our onshore pipeline assets through published tariffs (regulated by FERC) or contracted rates applied to volumes moved.



We have entered into throughput and deficiency agreements with BP Products with
respect to volumes transported on BP2, River Rouge and Diamondback that expire
December 31, 2023. Under these fee-based agreements, we provide transportation
services to BP Products, in exchange for BP Products' commitment to pay us the
applicable tariff rates for the minimum monthly volumes, whether or not such
volumes are physically shipped by BP Products through our pipelines.

We have entered into a throughput and deficiency agreement with our affiliate BP
Products North America, Inc. ("BP Products"), an indirect wholly owned
subsidiary of BP, for transporting diluent on the Diamondback pipeline under a
joint tariff agreement and a dedication agreement with a third-party carrier.
These agreements include a minimum volume requirement, under which BP Products
has committed to pay us an incentive rate for a fixed minimum volume during the
twelve-month running period from July 1, 2017 and each successive twelve-month
period thereafter through June 30, 2022, whether or not such volumes are
physically shipped through Diamondback. The parties have the option to allow the
two agreements to renew
annually for one additional year by not sending written notice of termination
six months prior to the expiration date.

KM Phoenix has terminals located across the United States within key product
trading hubs and highly strategic markets that support BP's refining, trading
and marketing businesses. KM Phoenix generates revenue primarily from truck rack
throughput, tank leasing, butane blending and pipeline transshipments.

Offshore Assets



Many of the contracts supporting our offshore assets include fee-based
life-of-lease transportation dedications and require producers to transport all
production from the specified fields connected to the pipeline for the life of
the related oil lease without a minimum volume commitment. This agreement
structure means that the dedicated production cannot be transported by any other
means, such as barges or another pipeline. The Mars system has a combination of
FERC-regulated tariff rates, intrastate rates, and contractual rates that apply
to throughput movements and inventory management fees for excess inventory, and
certain of those rates may be indexed with the FERC rate. Two of the Mars
agreements also include provisions to guarantee a return to the pipeline to
enable the pipeline to recover its investment, despite the uncertainty in
production volumes, by providing for an annual transportation rate adjustment
over a fixed period of time to achieve a fixed rate of return. The calculation
for the fixed rate of return is based on actual project costs and operating
costs. At the end of the fixed period, the rate will be locked in at a rate no
greater than the last calculated rate and adjusted annually thereafter at a rate
no less than zero percent and no greater than the FERC index.

The Proteus and Caesar pipelines have an order from the FERC declaring them to
be contract carriers with negotiated rates and services. On Proteus and Caesar,
the fees for the anchor shippers, which account for a majority of the volumes
dedicated to Proteus and Caesar, respectively, were set for the life of the
lease over the original lease volumes dedicated to Proteus and Caesar, and are
not subject to annual escalation under their oil transportation contracts. The
shippers have firm space that varies annually corresponding to their requested
maximum daily quantity forecasts. The majority of revenues on these pipelines
are
                                       59
--------------------------------------------------------------------------------

generated by anchor shippers based on the specified fee for all transported
volumes covered by oil transportation contracts with each shipper. Contracts
entered into in connection with later connections to Proteus and Caesar may have
different terms than the anchor shippers, including rates that vary with
inflation.

Cleopatra is also a contract carrier. Each shipper on Cleopatra has a contract
with negotiated rates. The rates are fixed for the anchor shippers' dedicated
leases, are not subject to annual escalation and generate the majority of
Cleopatra's revenues. Contracts for field connections for other shippers contain
a variety of rate structures.

Endymion is currently a contract carrier. However, it could be subject to
intrastate or FERC jurisdiction under certain circumstances in the future.
Endymion generates the majority of its revenues from contractual fees applied to
the transportation of oil into storage and from fees applied to per barrel
movements of oil out of storage (including volume incentive discounts for larger
shippers using storage). The rates are fixed for the anchor shippers'
agreements, are not subject to annual escalation and generate the majority of
Endymion's revenues. Agreements for other shippers may have different terms than
the anchor shippers, including rates that may vary with inflation.

Ursa is a crude oil gathering pipeline system that provides gathering and transportation services under a joint tariff extending from the Ursa Tension Leg Platform at Mississippi Canyon Block 809 to a connection with the Mars Oil Pipeline system at West Delta Block 143. From West Delta Block 143 oil is transported to Chevron's Fourchon terminal and LOOP's Clovelly terminal.

Fixed Loss Allowance and Inventory Management Fees



The tariffs applicable to BP2 and Mars include a fixed loss allowance ("FLA").
An FLA factor per barrel, a fixed percentage, is a separate fee under the crude
oil tariffs to cover evaporation, crude viscosity, temperature differences and
other losses in transit. As crude oil is transported, we and Mars earn
additional income based on the applicable FLA factor and the volume transported
by the customer and the applicable prices. Under the tariff applicable to BP2
and Mars, allowance oil related revenue is recognized using the average market
price for the relevant type of crude oil during the month the product is
transported.

In addition, Mars is entitled to inventory management fees for Louisiana offshore oil port storage.

How We Evaluate Our Operations



Partnership management uses a variety of financial and operating metrics to
analyze performance. These metrics are significant factors in assessing
operating results and profitability and include: (i) safety and environmental
metrics, (ii) revenue (including FLA) from throughput and utilization; (iii)
operating expenses and maintenance spend; (iv) Adjusted EBITDA (as defined
below); and (v) cash available for distribution (as defined below).

Preventative and Environmental Safety



We are committed to maintaining and improving the safety, reliability and
efficiency of Partnership operations. As noted above, we have worked with BP
Pipelines and the third-party operators of our assets to ensure that COVID-19
response and business continuity plans have been implemented across all of our
assets and operations. We have implemented reporting programs requiring all
employees and contractors of our Parent who provide services to us to record
environmental and safety related incidents. The Partnership's management team
uses these existing programs and data to evaluate trends and potential
interventions to deliver on performance targets. We integrate health,
occupational safety, process safety and environmental principles throughout
Partnership operations to reduce and eliminate environmental and safety related
incidents.

Throughput

We have historically generated substantially all of our revenue under long-term
agreements or FERC-regulated generally applicable tariffs by charging fees for
the transportation of products through our pipelines. The amount of revenue we
generate under these agreements depends in part on the volumes of crude oil,
natural gas, refined products and diluent on our pipelines.

Volumes on pipelines are primarily affected by the supply of, and demand for,
crude oil, natural gas, refined products and diluent in the markets served
directly or indirectly by Partnership assets. Results of operations are impacted
by our ability to:

•utilize any remaining unused capacity on, or add additional capacity to, Partnership pipeline systems;


                                       60
--------------------------------------------------------------------------------

•increase throughput volumes on Partnership pipeline systems by making
connections to existing or new third-party pipelines or other facilities,
primarily driven by the anticipated supply of and demand for crude oil, natural
gas, refined products and diluent;
•identify and execute organic expansion projects; and
•increase throughput volumes via acquisitions.

Storage Utilization
Storage utilization is a metric that we use to evaluate the performance of KM
Phoenix's storage and terminalling assets. We define storage utilization as the
percentage of the contracted capacity in barrels compared to the design capacity
of the tank.

Operating Expenses and Total Maintenance Spend

Operating Expenses



Management seeks to maximize profitability by effectively managing operating
expenses. These expenses are comprised primarily of labor expenses (including
contractor services), general materials, supplies, minor maintenance, utility
costs (including electricity and fuel) and insurance premiums. Utility costs
fluctuate based on throughput volumes and the grades of crude oil and types of
refined products we handle. Other operating expenses generally remain relatively
stable across broad ranges of throughput volumes, but can fluctuate from period
to period depending on the mix of activities performed during that period.

Total Maintenance Spend - Wholly Owned Assets



We calculate Total Maintenance Spend as the sum of maintenance expenses and
maintenance capital expenditures, excluding any reimbursable maintenance capital
expenditures. We track these expenses on a combined basis because it is useful
to understanding our total maintenance requirements. Total Maintenance Spend for
the years ended December 31, 2021 and 2020, is shown in the table below:
                                                        Years Ended December 31,
                                                            2021                  2020

$ 4.8

(1)Relates to the portion of maintenance capital for the Griffith Station Incident reimbursable by insurance.



The Partnership seeks to maximize profitability by effectively managing
maintenance expenses, which consist primarily of safety and environmental
integrity programs. We seek to manage maintenance expenses on owned and operated
pipelines by scheduling maintenance over time to avoid significant variability
in maintenance expenses and minimize impact on cash flows, without compromising
our commitment to safety and environmental stewardship.

Maintenance expenses represent the costs we incur that do not significantly
extend the useful life or increase the expected output of property, plant and
equipment. These expenses include pipeline repairs, replacements of immaterial
sections of pipelines, inspections, equipment rentals and costs incurred to
maintain compliance with existing safety and environmental standards,
irrespective of the magnitude of such compliance expenses. Maintenance expenses
may vary significantly from period to period because certain expenses are the
result of scheduled safety and environmental integrity programs, which occur on
a multi-year cycle and require substantial outlays.

Maintenance capital expenditures represent expenditures to sustain operating
capacity or operating income over the long term. Examples of maintenance capital
expenditures include expenditures made to purchase new or replacement assets or
extend the useful life of existing assets. These expenditures includes repairs
and replacements of storage tanks, replacements of significant sections of
pipelines and improvements to an asset's safety and environmental standards.

                                       61
--------------------------------------------------------------------------------

Adjusted EBITDA and Cash Available for Distribution



The Partnership defines Adjusted EBITDA as net income before net interest
expense, income taxes, gain or loss from disposition of property, plant and
equipment, and depreciation and amortization, plus cash distributed to the
Partnership from equity method investments for the applicable period, less
income from equity method investments. The Partnership defines Adjusted EBITDA
attributable to the Partnership as Adjusted EBITDA less Adjusted EBITDA
attributable to non-controlling interests. We present these financial measures
because we believe replacing our proportionate share of our equity method
investments' net income with the cash received from such equity method
investments more accurately reflects the cash flow from our business, which is
meaningful to our investors.

We compute and present cash available for distribution and define it as Adjusted
EBITDA attributable to the Partnership less maintenance capital expenditures
attributable to the Partnership, net interest paid/received, cash reserves,
income taxes paid and net adjustments from volume deficiency payments
attributable to the Partnership. Cash available for distribution does not
reflect changes in working capital balances.

Adjusted EBITDA and cash available for distribution are non-GAAP supplemental
financial measures, which are metrics that management and external users of our
consolidated financial statements, such as industry analysts, investors, lenders
and rating agencies, may use to assess:

•operating performance as compared to other publicly traded partnerships in the
midstream energy industry, without regard to historical cost basis or financing
methods;
•ability to generate sufficient cash to support decisions to make distributions
to our unitholders;
•ability to incur and service debt and fund capital expenditures; and
•viability of acquisitions and other capital expenditure projects and the
returns on investment of various investment opportunities.

We believe that the presentation of Adjusted EBITDA and cash available for
distribution provides useful information to investors in assessing our financial
condition and results of operations. The GAAP measures most directly comparable
to Adjusted EBITDA and cash available for distribution are net income and net
cash provided by operating activities, respectively. Adjusted EBITDA and cash
available for distribution should not be considered as an alternative to GAAP
net income or net cash provided by operating activities.

Adjusted EBITDA and cash available for distribution 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. You should not consider
Adjusted EBITDA or cash available for distribution in isolation or as a
substitute for analysis of our results as reported under GAAP. Additionally,
because Adjusted EBITDA and cash available for distribution may be defined
differently by other companies in our industry, our definition of Adjusted
EBITDA and cash available for distribution may not be comparable to similarly
titled measures of other companies, thereby diminishing its utility. Please read
"Reconciliation of Non-GAAP Measures" section below for the reconciliation of
net income and cash provided by operating activities to Adjusted EBITDA and cash
available for distribution.

Factors Affecting Our Business



Partnership business can be negatively affected by sustained downturns or slow
growth in the economy in general and is impacted by shifts in supply and demand
dynamics, the mix of services requested by the customers of our pipelines,
competition and changes in regulatory requirements affecting our customers'
operations. The ultimate magnitude and duration of the COVID-19 pandemic,
resulting governmental restrictions on the mobility of consumers and the related
impact on demand and the U.S. and global economy and capital markets is
uncertain. As of the date of this Annual Report, all of our assets remain
operational.

Regulation



Interstate common carrier pipelines are subject to regulation by various
federal, state and local agencies including the FERC, the Environmental
Protection Agency and the Department of Transportation. On December 17, 2020, in
Docket No. RM20-14-000, FERC issued an order establishing a new index level of
PPI-FG plus 0.78% for the five-year period
                                       62
--------------------------------------------------------------------------------

commencing July 1, 2021 ("December 2020 Order"). Requests for rehearing of the
December 2020 Order were filed with FERC. On January 20, 2022, FERC issued an
order on rehearing that reverses its December 2020 Order on the five-year review
of the oil pipeline rate index. FERC lowered the index from PPI-FG plus 0.78% to
PPI-FG minus 0.21%. The rehearing order also directs oil pipelines to recompute
their rate ceiling levels for July 1, 2021 through June 30, 2022, based upon the
index of PPI-FG minus 0.21%, to be effective March 1, 2022. Additionally, FERC
issued a notice that adjusts the annual change in the oil pipeline rate index
for the period July 1, 2021 through June 30, 2022, to implement the PPI-FG minus
0.21% index, explaining that oil pipelines must multiply their July 1, 2020
through June 30, 2021 index ceiling levels by positive 0.984288 to recompute
their July 1, 2021 through June 30, 2022 index ceiling levels.

On May 27, 2021, the Department of Homeland Security's Transportation Security
Administration ("TSA") announced Security Directive Pipeline-2021-01 that
requires us, as a critical pipeline owner, to report confirmed and potential
cybersecurity incidents to the DHS Cybersecurity and Infrastructure Security
Agency ("CISA") and to designate a Cybersecurity Coordinator. It also requires
BP Pipelines and the third-party operators of our assets to review current
practices as well as to identify any gaps and related remediation measures to
address cyber-related risks and report the results to TSA and CISA within 30
days. We designated a Cybersecurity Coordinator, developed a plan to comply with
mandatory reporting timeframes and completed the vulnerability assessment
required under this directive on June 25, 2021. On July 20, 2021, the TSA issued
a second Security Directive. We have evaluated the impacts of this second
directive to our pipeline business and have made significant progress in
compliance.

Financing

We expect to fund future capital expenditures from a mixture of sources, including cash on hand, cash flow from operations and borrowings available under our credit facility.



We intend to make cash distributions to unitholders at a minimum distribution
rate of $0.2625 per unit per quarter ($1.05 per unit on an annualized basis).
However, the Merger Agreement contains a provision that, during the period from
December 19, 2021 until consummation of the Merger, in no event will any regular
quarterly cash distribution declared or paid to unitholders be less than $0.3475
per unit.

Based on the terms of our cash distribution policy, we expect that we will distribute to unitholders and the general partner, as the holder of IDRs, most of the cash generated by operations.

Griffith Station Incident



On June 13, 2019, a building fire occurred at the Griffith Station on BP2.
Management performed an evaluation of the assets and determined that an
impairment was required. We have incurred $0.3 million, $0.4 million, and $1.6
million in response expenses during the years ended December 31, 2021, 2020, and
2019 respectively. Reimbursable costs associated with the incident were offset
with an insurance receivable. We received $2.5 million and $2.9 million of
insurance proceeds during the years ended December 31, 2021 and 2020,
respectively. Future proceeds from insurance claims would be recognized as a
gain.

Year Ended December 31, 2021 Compared to Year Ended December 31, 2020

Total revenue decreased by $9.0 million, or 7.0%, in the year ended December 31, 2021, compared to the year ended December 31, 2020, primarily due to the following:



•Decrease of $9.2 million from the recognition of deficiency revenue compared to
the prior period, in part reflecting the lower volume threshold in the MVC
agreement.
•Decrease of $6.5 million in tariff revenue driven by a $5.4 million decrease on
River Rouge, and a $3.7 million decrease on Diamondback, partially offset by a
$2.6 million increase on BP2.
•Increase of $6.7 million in FLA revenue from BP2 driven by an increase in
throughput volume and an increase in FLA prices realized.
•Throughput volume decreased by 6.9 millions barrels driven by a 3.3 million
barrels decrease on River Rouge, a 7.2 million barrels decrease on Diamondback,
partially offset by an increase of 3.6 million barrels on BP2.

Operating expenses increased by $0.9 million, or 4.6%, in the year ended December 31, 2021, compared to the year ended December 31, 2020, primarily attributable to an increase in insurance expense, partially offset by decrease in variable expense due to lower volumes.

Maintenance expenses decreased by $0.4 million or 10.5% in the year ended December 31, 2021, compared to the year ended December 31, 2020, due to reduced pipeline inspection and repair activity.



General and administrative expenses increased by $3.3 million or 19.5% in the
year ended December 31, 2021, compared to the year ended December 31, 2020,
primarily driven by a $1.9 million increase in merger-related expenditures and a
$1.4 million increase in the omnibus agreement annual fee.

                                       65
--------------------------------------------------------------------------------

Income from equity method investments decreased by $4.3 million, or 3.9%, in the
year ended December 31, 2021 compared to the year ended December 31, 2020
primarily due to the impacts of Hurricane Ida on Mars, offset by an increase in
earnings from the Mardi Gras Joint Ventures.

Interest expense, net decreased by $3.6 million in the year ended December 31,
2021 compared to the year ended December 31, 2020 due to lower interest rates
tied to LIBOR.

Net income attributable to non-controlling interests increased by $2.4 million
or 12.1% in the year ended December 31, 2021 compared to the year ended December
31, 2020, due to the increase in earnings from Mardi Gras in the period.

Capital Resources and Liquidity



Currently, we expect our primary ongoing sources of liquidity to be cash
generated from operations (including distributions from our equity method
investments), and, as needed, borrowings under our existing credit facility. The
entities in which we own an interest may also incur debt. We believe that cash
generated from these sources will be sufficient to meet our short-term working
capital requirements and long-term capital expenditure requirements and to make
quarterly cash distributions. We currently have no transactions, agreements or
other contractual arrangements that would result in off-balance sheet
liabilities or impact our liquidity.

Based upon current expectations for the fiscal year 2022, we believe that our cash on hand and cash flow from operations will be sufficient to fund our operations for 2022. As of December 31, 2021, our cash on hand was $136.9 million.



The existing credit facility, which as of December 31, 2021 has $132 million
available for borrowing, will terminate on October 30, 2022. Our relationship
with the affiliate of BP is stable and management has the intent and believes
the Partnership will have the ability to amend the credit facility, if
necessary.

Our only debt outstanding is our $468 million borrowed under our term loan with
an affiliate of BP, and there are no principal payments required with respect to
that facility until 2025. Our relationship with the affiliate of BP is stable
and management has the intent and believes the Partnership will have the ability
to consummate a refinance, if necessary. If a refinance is not consummated, the
$468 million principal will need to be paid on or before February 24, 2025.

Cash Distributions



The board of directors of our general partner has adopted a cash distribution
policy pursuant to which we intend to pay a minimum quarterly distribution of
$0.2625 per unit per quarter, which equates to approximately $27.5 million per
quarter, or $110.0 million per year in the aggregate, based on the number of
common and subordinated units outstanding as of December
                                       67
--------------------------------------------------------------------------------

31, 2021. We intend to pay such distributions to the extent we have sufficient cash after the establishment of cash reserves and the payment of expenses, including payments to our general partner and its affiliates.

Revolving Credit Facility



On October 30, 2017, the Partnership entered into a $600.0 million unsecured
revolving credit facility agreement with an affiliate of BP. The credit facility
terminates on October 30, 2022 and provides for certain covenants, including the
requirement to maintain a consolidated leverage ratio, which is calculated as
total indebtedness to consolidated EBITDA (as defined in the credit facility),
not to exceed 5.0 to 1.0, subject to a temporary increase in such ratio to 5.5
to 1.0 in connection with certain material acquisitions. In addition, the
limited liability company agreement of the General Partner requires the approval
of BP Holdco prior to the incurrence of any indebtedness that would cause our
leverage ratio to exceed 4.5 to 1.0.

The credit facility also contains customary events of default, such as (i)
nonpayment of principal when due, (ii) nonpayment of interest, fees or other
amounts, (iii) breach of covenants, (iv) misrepresentation, (v) cross-payment
default and cross-acceleration (in each case, to indebtedness in excess of $75.0
million) and (vi) insolvency. Additionally, the credit facility limits our
ability to, among other things: (i) incur or guarantee additional debt, (ii)
redeem or repurchase units or make distributions under certain circumstances;
and (iii) incur certain liens or permit them to exist. Indebtedness under this
facility bears interest at the 3-month London Interbank Offered Rate ("LIBOR")
plus 0.85%. This facility includes customary fees, including a commitment fee of
0.10% and a utilization fee of 0.20%.

In connection with an acquisition in the fourth quarter of 2018, we borrowed $468.0 million from the credit facility. This amount was outstanding at December 31, 2019, and repaid on March 13, 2020.

Term Loan Facility Agreement



On February 24, 2020, the Partnership entered into a $468.0 million Term Loan
Facility Agreement ("term loan") with an affiliate of BP. On March 13, 2020,
proceeds were used to repay outstanding borrowings under the existing credit
facility. The term loan has a final repayment date of February 24, 2025, and
provides for certain covenants, including the requirement to maintain a
consolidated leverage ratio, which is calculated as total indebtedness to
consolidated EBITDA, not to exceed 5.0 to 1.0, subject to a temporary increase
in such ratio to 5.5 to 1.0 in connection with certain material acquisitions.
Simultaneous with this transaction, we entered into a First Amendment to Short
Term Credit Facility Agreement ("First Amendment") whereby the lender added a
provision that indebtedness under both the term loan and credit facility shall
not exceed $600.0 million. All other terms of the credit facility remain the
same. As of December 31, 2021, the Partnership was in compliance with the
covenants contained in the credit facility and term loan.

Cash Flows from Our Operations



Operating Activities. We generated $188.1 million in cash flow from operating
activities in the year ended December 31, 2021, compared to the $190.4 million
generated in the year ended December 31, 2020. The $2.3 million decrease in cash
flows from operations primarily resulted from a $14.4 million decrease in net
income and distributions of earnings received from equity method investments,
offset by net increases from working capital changes of approximately $12.1
million. Changes in working capital were principally driven by a $6.3 million
decrease in prepaid insurance expenses combined with a $4.0 million increase in
current liabilities.

Investing Activities. Our cash flows used in investing activities were $0.4
million in the year ended December 31, 2021 and cash flows generated by
investing activities were $12.4 million in the year ended December 31, 2020. The
$12.8 million decrease in cash inflows from investing activities is primarily
due to an increase of $13.7 million in funds used for capital expenditures,
primarily related to the River Rouge onshore capacity increase project, a
decrease of $0.7 million from proceeds from insurance claims related to Griffith
Station incident, partially offset by an increase of $1.6 million in
distribution in excess of earnings from equity method investments.

Financing Activities. Our cash flows used in financing activities were $177.7
million in the year ended December 31, 2021 and $174.7 million in the year ended
December 31, 2020. The $3.0 million increase in cash outflows used in financing
activities is due to distributions to non-controlling interests in Mardi Gras.

Capital Expenditures

Our operations can be capital intensive, requiring investment to expand, upgrade or enhance existing operations and to meet environmental and operational regulations. Our capital requirements consist of maintenance capital expenditures and expansion


                                       68
--------------------------------------------------------------------------------

capital expenditures, both as defined in our partnership agreement. We are required to distinguish between maintenance capital expenditures and expansion capital expenditures in accordance with our Partnership agreement.

In the year 2021, we incurred $12.9 million expansion capital expenditures for
the River Rouge onshore capacity increase project and $4.1 million maintenance
capital expenditures primarily associated with the Griffith Station Electrical
and Controls project.

In the year 2020, we incurred $4.1 million expansion capital expenditures for
the River Rouge onshore capacity increase project and $3.6 million maintenance
capital expenditures. The maintenance capital expenditures were primarily
associated with BP2 motor purchase and installation, and Griffith Station
recovery which included a building, lighting, power, relay and PLC panels.

Critical Accounting Policies and Estimates



Critical accounting policies are those that are important to our financial
condition and require management's most difficult, subjective or complex
judgments. Different amounts would be reported under different operating
conditions or under alternative assumptions. We have evaluated the accounting
policies used in the preparation of the consolidated financial statements of the
Partnership and related notes thereto and believe those policies are reasonable
and appropriate.

We apply those accounting policies that we believe best reflect the underlying
business and economic events, consistent with GAAP. Our more critical accounting
policies include those related to equity method investments and revenue
recognition. Inherent in such policies are certain key assumptions and
estimates. We periodically update the estimates used in the preparation of the
financial statements based on our latest assessment of the current and projected
business and general economic environment. Our significant accounting policies
are summarized in   Note 2 -     Summary of Significant Accounting Policies 

in

the Notes to Consolidated Financial Statements. We believe the following to be our most critical accounting policies applied in the preparation of our financial statements.

Accounting for Equity Method Investments



The Partnership maintains investments in several joint ventures that are
accounted for under the equity method of accounting. Under the equity method of
accounting, investments are recorded at historical cost as an asset and adjusted
for capital contributions, dividends received, and the Partnership's share of
the investees' earnings or losses, which is recorded as a component of income
from equity method investments. As of December 31, 2021, the Partnership's
equity method investments balance was $504.7 million, and for the year ended
December 31, 2021, the Partnership's income from equity method investments was
$106.5 million.

The Partnership does not have a controlling interest in our investments in joint
ventures; however, because of the significance of the investments to our
financial statements our management exercises critical judgments when assessing
the results of the joint ventures' operations and the accounting judgments made
by the operators. This requires management to rely on their experience in the
industry and their knowledge of the joint ventures involved in making final
assessments on the recognition of operating results as reported to the
Partnership by the operators.

The Partnership assesses its equity method investments for impairment whenever
changes in the facts and circumstances indicate a loss in value has occurred.
When the loss is deemed to be other-than-temporary, the carrying value of the
equity method investment is written down to fair value. For the years December
31, 2021 and 2020, there were no indicators of an other-than-temporary
impairment identified.

Revenue Recognition



Our revenues are primarily generated from crude oil, refined products and
diluent transportation services. We recognize revenue over time or at a point in
time, depending on the nature of the performance obligations contained in the
respective contract with customers. A performance obligation is our unit of
account and it represents a promise in a contract to transfer goods or services
to the customer. The contract transaction price, which is the amount of
consideration to which an entity expects to be entitled in exchange for
transferring promised goods or services to a customer, is allocated to each
performance obligation and recognized as revenue when or as the performance
obligation is satisfied.

We entered into multiple long-term fee-based transportation agreements with BP
Products, an indirect wholly owned subsidiary of BP. Under these agreements, BP
Products has committed to pay us the minimum volumes at the applicable rates for
each of the twelve-month measurement periods specified by the applicable
agreements whether or not such volumes are physically transported through our
pipelines. BP Products is allowed to make up for shortfall volumes during each
of the measurement periods.

Contracts with BP Products, including the allowance oil arrangements discussed
below, are accounted for as separate arrangements because they do not meet the
criteria for combination. We record revenue for crude oil, refined products and
diluent transportation over the period in which they are earned (i.e., either
physical delivery of product has taken place, or the services designated in the
contract have been performed). Revenue from transportation services is
recognized upon delivery or receipt based on contractual rates related to
throughput volumes. We accrue revenue based on services rendered but not billed
for that accounting month.

Billings to BP Products for deficiency volumes under its minimum volume
commitments, if any, are recorded in deferred revenues and credits on our
consolidated balance sheets, as BP Products has the right to make up the
deficiency volumes within the measurement period specified by the agreements. We
consider this deferred revenue as breakage revenue and evaluate applicable
accounting guidance to determine when or if to recognize the amounts into
revenue. We recognize the breakage amount as revenue when the likelihood of the
customer exercising its remaining rights becomes remote. The timing of
recognition of breakage revenue requires management to make judgements that
primarily impact our interim financial statements since our most significant MVC
contracts have a 12-month measurement period that coincides with the calendar
year.

The unfulfilled obligations in our revenue contracts are our obligations to
transport certain volumes of crude or diluent molecules (throughput) for our
customers throughout the term of each contract. The terms of the contract
require the customer to deliver a specified quantity of molecules or minimum
volume each day with a right to make up any short fall within the 12 month
measurement period of each contract. At the end of each quarterly reporting
period we analyze the customer's actual shipments compared to their minimum
volume commitments to measure the level of fulfillment toward the contracted
minimum volume commitments. This analysis also includes the review of the
capacity of each pipeline available for the customer to deliver the required
volume to make up for any shortfall, current forecast of the customers' future
shipments, an assessment of whether management thinks the customers can make up
for the shortfall and any impact market conditions have on the probability of
customers making up the shortfall. If our assessment concludes that it is remote
that the customer will make up for volume shortfalls and require performance of
the unfulfilled obligations, the appropriate level of breakage is recognized
into revenue.
