Executive Summary

Company Overview

We are a Delaware limited partnership formed on July 17, 2013 that has elected
to be taxed as a corporation for United States federal income tax purposes. As
of September 30, 2020, our sole cash-generating assets consisted of (i) a 100%
managing member interest in Plains All American GP LLC ("GP LLC") that has also
elected to be taxed as a corporation for United States federal income tax
purposes and (ii) an approximate 77% limited partner interest in AAP through our
direct ownership of approximately 186.3 million AAP units and indirect ownership
of approximately 1.0 million AAP units through GP LLC. GP LLC is a Delaware
limited liability company that also holds the non-economic general partner
interest in AAP. AAP is a Delaware limited partnership that, as of September 30,
2020, directly owned a limited partner interest in PAA through its ownership of
approximately 245.8 million PAA common units (approximately 31% of PAA's total
outstanding common units and Series A preferred units combined). AAP is the sole
member of PAA GP LLC ("PAA GP"), a Delaware limited liability company that
directly holds the non-economic general partner interest in PAA.

PAA owns and operates midstream energy infrastructure and provides logistics
services primarily for crude oil, NGL and natural gas. PAA owns an extensive
network of pipeline transportation, terminalling, storage and gathering assets
in key crude oil and NGL producing basins and transportation corridors and at
major market hubs in the United States and Canada. PAA's operations are
conducted directly and indirectly through its operating subsidiaries and are
managed through three operating segments: Transportation, Facilities and Supply
and Logistics. See "-Results of Operations-Analysis of Operating Segments" for
further discussion.

Recent Events & Outlook



During the first quarter of 2020, COVID-19 escalated into a global pandemic,
which led to widespread shelter-in-place or similar requirements throughout
North America and across the world, resulting in significantly reduced energy
demand. As a result, North American producers responded aggressively by shutting
in significant levels of production early in the second quarter, which mitigated
the pace of crude oil inventory builds and the risk of testing storage maximums.
Subsequently, United States refinery utilization increased, the previously steep
contango market structure tempered, and crude oil prices improved to more
constructive levels. This supported the ability for producers to bring a
substantial portion of previously shut-in production back on line and resume
completion activity during the third quarter at a level likely to be sufficient
to offset natural declines.

Additionally, in the third quarter, United States Lower 48 horizontal crude oil
rig counts increased modestly but as of quarter end represented approximately
25% of peak levels reached in 2019. Additionally, although United States
inventories of crude oil and distillate had constructive draws during the third
quarter, they remained elevated relative to their prior five-year range. The
combination of steep shale declines relative to drilling and completion
activity, substantial inventory overhang, and the potential for a prolonged
demand recovery has challenged the ability of North American liquids production
to return to a sustainable growth trajectory in 2020, and which is likely to
persist into 2021. Furthermore, we expect a continuation of elevated near-term
market uncertainty to be driven by various risks, including potential COVID-19
resurgence, regulatory changes and evolving geo-political dynamics. In
aggregate, we expect these market dynamics to have a negative impact on our
business relative to pre-pandemic levels, with the impacts in 2021 potentially
being more pronounced than in 2020.

We believe our business is well positioned to manage through the current
challenging market environment. We expect global demand for hydrocarbons will
recover, which should drive a return of constructive crude oil price levels and
higher production levels in key onshore shale basins, which should support
growing demand for our assets.

In addition, in response to the challenging near-term market conditions, we have
taken steps to further strengthen our balance sheet, liquidity and long-term
financial flexibility. These actions include significantly reducing and
continuing to challenge our capital program, reducing the amount of PAA's common
unit distribution payable, progressing asset sales, and reducing costs, while
remaining focused on operating safely and responsibly.

Specifically, since April, we have reduced our 2020/2021 capital program by $850
million, or 37%, and have decreased PAA's common unit distributions and our
Class A share distributions by 50% versus the distributions paid in February
2020, which reflects a reduction of $525 million on an annualized basis. We have
completed approximately $450 million of asset sales (which amount includes an
approximately $200 million asset sale that closed in October 2020). While each
of these actions should contribute to a stronger balance sheet and enhanced
liquidity and long-term financial flexibility, we can provide no assurance that
we will be able to effect certain future actions (such as additional capital
reductions, asset sales and expense reductions) and additional actions may be
necessary to achieve our balance sheet, liquidity and financial security
objectives. See "Risk Factors-Risks Related to PAA's Business" discussed in Item
1A. of our 2019 Annual Report on Form 10­K and Part II, Item 1A. "Risk Factors"
in our Quarterly Report on Form 10-Q for the period ended March 31, 2020.

While some modifications in our operations have been necessary to deal with
risks associated with the COVID-19 pandemic, we have not experienced any
material constraints in our ability to continue our essential business functions
and have not incurred any significant additional operating costs as a result of
the pandemic, including costs associated with navigating the applicable
shelter-in-place or similar restrictions and implementing our business
continuity plans. We remain focused on the health and safety of our workforce,
and have modified our operations in ways that we believe are prudent and
appropriate in order to protect our employees while continuing to operate our
assets in an effective, safe and responsible manner.

In addition, many governments have enacted or are contemplating measures to
provide aid and economic stimulus in response to the COVID-19 pandemic. These
measures include actions by both the United States federal government and the
government of Canada. There has been no material impact to our financial
position, results of operations or cash flows resulting from these measures.
However, our Canadian subsidiary participated in a wage subsidy program during
the second and third quarters of 2020 for subsidies totaling approximately $20
million. The impact of such subsidies is included in the line items "Field
operating costs" and "Segment general and administrative expenses" of the
applicable segments. See "-Results of Operations-Analysis of Operating Segments"
for further discussion.

Table of Contents Overview of Operating Results, Capital Investments and Other Significant Activities



The macroeconomic and industry specific challenges discussed above have resulted
in a number of impairment charges recognized during 2020 as discussed further
below. See "-Liquidity and Capital Resources" for additional discussion of the
expected and potential impact of COVID-19 and related market conditions on our
business.

During the first nine months of 2020, we recognized a net loss of $2.417 billion
as compared to net income of $1.771 billion recognized during the first nine
months of 2019. The net loss for the period was driven by goodwill impairment
losses of $2.5 billion and was also impacted by non-cash impairment charges of
approximately $815 million related to the write-down of certain pipeline and
other long-lived assets, certain of our investments in unconsolidated entities,
and assets upon classification as held for sale. In addition, we recognized
approximately $233 million of inventory valuation adjustments due to declines in
commodity prices primarily during the first quarter of 2020.

Our results for the comparative period were also impacted by:



•Less favorable results from our Supply and Logistics segment due to less
favorable crude oil differentials, lower NGL margins and the unfavorable impact
of the mark-to-market of certain derivative instruments, resulting from losses
recognized in the 2020 period compared to gains in the 2019 period, partially
offset by the favorable impact of contango market conditions during the second
and third quarters of 2020;

•Less favorable results from our Transportation segment driven by lower volumes
from shut-ins of crude oil production, reduced drilling and completion activity
and compressed regional basis differentials, a portion of which are covered by
minimum volume commitments that will be made up or paid for in future periods,
and lower pipeline loss allowance revenue in 2020 due to lower prices and
volumes, partially offset by lower field operating costs;

•Higher depreciation and amortization expense in the 2020 period primarily due
to additional depreciation expense associated with the completion of various
investment capital projects and by a reduction in the useful lives of certain
assets;

•Unfavorable foreign currency impacts of $20 million recognized in "Other income/(expense), net" in the 2020 period;



•A gain of $21 million recognized in the current period related to the sale of a
portion of our interest in Saddlehorn Pipeline Company, LLC in February 2020,
compared to a non-cash gain of $269 million recognized in the 2019 period
related to a fair value adjustment resulting from the accounting for the
contribution of our undivided joint interest in the Capline pipeline system for
an equity interest in Capline Pipeline Company LLC; partially offset by

•Favorable results from our Facilities segment primarily due to lower field operating costs; and

•The income tax benefit associated with lower earnings at PAA, including goodwill impairment losses, on income attributable to PAGP.

See further discussion of our operating results in the "-Results of Operations-Analysis of Operating Segments" and "-Other Income and Expenses" sections below.



We invested $785 million in midstream infrastructure projects during the nine
months ended September 30, 2020, which primarily related to projects under
development in the Permian Basin. Additionally, during the first quarter of
2020, we acquired approximately $310 million of assets, which primarily included
a crude oil gathering system located in the Delaware Basin. See the
"-Acquisitions and Capital Projects" section below for additional information.

In June 2020, PAA completed the issuance of $750 million, 3.80% senior notes due
September 2030. We used the net proceeds from this offering of $742 million,
after deducting the underwriting discount and offering expenses, to repay the
principal amounts of PAA's 5.00% senior notes due February 2021 (which were
redeemed on November 3, 2020). Prior to such repayment, we used a portion of the
proceeds to repay outstanding borrowings under PAA's commercial paper program
and credit facilities and for general partnership purposes.

We paid approximately $667 million of cash distributions to our Class A shareholders and noncontrolling interests during the nine months ended September 30, 2020.



On November 2, 2020, we announced that the board of directors of our general
partner has approved a $500 million common equity repurchase program (the
"Program") to be utilized as an additional method of returning capital to
investors. The Program authorizes the repurchase from time to time of up to $500
million of PAA common units and/or PAGP Class A shares via open market purchases
or negotiated transactions conducted in accordance with applicable regulatory
requirements. Ultimately, the amount, timing and pace of potential repurchase
activity will be determined by a number of factors, including market conditions,
PAA's financial performance and flexibility, PAA's actual and expected Free Cash
Flow after distributions, the absolute and relative equity prices of PAA common
units and PAGP Class A shares, and the extent to which PAA is positioned to
achieve and maintain its targeted leverage ratio. No time limit has been set for
completion of the Program, and the Program may be suspended or discontinued at
any time. The Program does not obligate PAA or us to acquire a particular number
of PAA common units or PAGP Class A shares. Any PAA common units or PAGP Class A
shares that are repurchased will be canceled.

(1)"Investment capital" was previously termed "Expansion capital". Although what
is included in this category has not changed, we consider the term "Investment
capital" to be more descriptive.
(2)Contributions to unconsolidated entities related to investment capital
projects of such entities are recognized in "Investment capital." We account for
our investments in such entities under the equity method of accounting.
(3)Capital expenditures made to expand the existing operating and/or earnings
capacity of our assets are classified as "Investment capital." Capital
expenditures for the replacement and/or refurbishment of partially or fully
depreciated assets in order to maintain the operating and/or earnings capacity
of our existing assets are classified as "Maintenance capital."

Investment Capital Projects

In April 2020, in response to the current dynamic and uncertain market
conditions, we announced our plan to significantly reduce and continue to
challenge our capital program. Total investment capital for 2020/2021 is now
targeted to be approximately $1.45 billion, or $850 million (37%) lower than the
previously targeted $2.3 billion investment capital program, and $1.45 billion
(50%) lower when eliminating $600 million of assumed joint venture project
financing (net to our share) for the Red Oak project, which was deferred in
March 2020. Subsequently, the partners of Red Oak determined that the project
would not proceed as previously contemplated. The balance of the investment
capital reductions relate to cancellations, cost savings and scope adjustments
to other investment capital projects. The following table summarizes our notable
projects in progress during 2020 and the estimated cost for the year ending
December 31, 2020 (in millions):

** Indicates that variance as a percentage is not meaningful. (1)Segment Adjusted EBITDA is the measure of segment performance that is utilized by our CODM to assess performance and allocate resources among our operating segments. This measure is adjusted for certain items, including those that our CODM believes impact comparability of results across periods. See Note 13 to our Condensed Consolidated Financial Statements for additional discussion of such adjustments.

Non-GAAP Financial Measures

To supplement our financial information presented in accordance with GAAP, management uses additional measures known as "non-GAAP financial measures" in its evaluation of past performance and prospects for the future.



The primary additional measure used by management is earnings before interest,
taxes, depreciation and amortization (including our proportionate share of
depreciation and amortization of unconsolidated entities), gains and losses on
asset sales and asset impairments, goodwill impairment losses and gains on and
impairments of investments in unconsolidated entities, adjusted for certain
selected items impacting comparability ("Adjusted EBITDA").

Our definition and calculation of certain non-GAAP financial measures may not be
comparable to similarly-titled measures of other companies. Adjusted EBITDA is
reconciled to Net Income/(Loss), the most directly comparable measure as
reported in accordance with GAAP, and should be viewed in addition to, and not
in lieu of, our Condensed Consolidated Financial Statements and accompanying
notes.

Management believes that the presentation of Adjusted EBITDA provides useful
information to investors regarding our performance and results of operations
because this measure, when used to supplement related GAAP financial measures,
(i) provides additional information about our core operating performance,
(ii) provides investors with the same financial analytical framework upon which
management bases financial, operational, compensation and planning/budgeting
decisions and (iii) presents measures that investors, rating agencies and debt
holders have indicated are useful in assessing us and our results of operations.
This non-GAAP measure may exclude, for example, (i) charges for obligations that
are expected to be settled with the issuance of equity instruments, (ii) gains
or losses on derivative instruments that are related to underlying activities in
another period (or the reversal of such adjustments from a prior period), gains
and losses on derivatives that are related to investing activities (such as the
purchase of linefill) and inventory valuation adjustments, as applicable,
(iii) long-term inventory costing adjustments, (iv) items that are not
indicative of our core operating results and business outlook and/or (v) other
items that we believe should be excluded in understanding our core operating
performance. This measure may further be adjusted to include amounts related to
deficiencies associated with minimum volume commitments whereby we have billed
the counterparties for their deficiency obligation and such amounts are
recognized as deferred revenue in "Other current liabilities" in our Condensed
Consolidated Financial Statements. Such amounts are presented net of applicable
amounts subsequently recognized into revenue. We have defined all such items as
"selected items impacting comparability." We do not necessarily consider all of
our selected items impacting comparability to be non-recurring, infrequent or
unusual, but we believe that an understanding of these selected items impacting
comparability is material to the evaluation of our operating results and
prospects.

Although we present selected items impacting comparability that management considers in evaluating our performance, you should also be aware that the items presented do not represent all items that affect comparability between the periods presented. Variations in our operating results are also caused by changes in volumes, prices, exchange rates, mechanical interruptions, acquisitions, investment capital projects and numerous other factors as discussed, as applicable, in "Analysis of Operating Segments."

(2)We use derivative instruments for risk management purposes, and our related
processes include specific identification of hedging instruments to an
underlying hedged transaction. Although we identify an underlying transaction
for each derivative instrument we enter into, there may not be an accounting
hedge relationship between the instrument and the underlying transaction. In the
course of evaluating our results of operations, we identify the earnings that
were recognized during the period related to derivative instruments for which
the identified underlying transaction does not occur in the current period and
exclude the related gains and losses in determining Adjusted EBITDA. In
addition, we exclude gains and losses on derivatives that are related to
investing activities, such as the purchase of linefill. We also exclude the
impact of corresponding inventory valuation adjustments, as applicable. See
Note 10 to our Condensed Consolidated Financial Statements for a comprehensive
discussion regarding our derivatives and risk management activities.
(3)We carry crude oil and NGL inventory that is comprised of minimum working
inventory requirements in third-party assets and other working inventory that is
needed for our commercial operations. We consider this inventory necessary to
conduct our operations and we intend to carry this inventory for the foreseeable
future. Therefore, we classify this inventory as long-term on our balance sheet
and do not hedge the inventory with derivative instruments (similar to linefill
in our own assets). We treat the impact of changes in the average cost of the
long-term inventory (that result from fluctuations in market prices) and
write-downs of such inventory that result from price declines as a selected item
impacting comparability. See Note 5 to our Consolidated Financial Statements
included in Part IV of our 2019 Annual Report on Form 10-K for additional
inventory disclosures.
(4)We have certain agreements that require counterparties to deliver, transport
or throughput a minimum volume over an agreed upon period. Substantially all of
such agreements were entered into with counterparties to economically support
the return on our capital expenditure necessary to construct the related asset.
Some of these agreements include make-up rights if the minimum volume is not
met. We record a receivable from the counterparty in the period that services
are provided or when the transaction occurs, including amounts for deficiency
obligations from counterparties associated with minimum volume commitments. If a
counterparty has a make-up right associated with a deficiency, we defer the
revenue attributable to the counterparty's make-up right and subsequently
recognize the revenue at the earlier of when the deficiency volume is delivered
or shipped, when the make-up right expires or when it is determined that the
counterparty's ability to utilize the make-up right is remote. We include the
impact of amounts billed to counterparties for their deficiency obligation, net
of applicable amounts subsequently recognized into revenue, as a selected item
impacting comparability. We believe the inclusion of the contractually committed
revenues associated with that period is meaningful to investors as the related
asset has been constructed, is standing ready to provide the committed service
and the fixed operating costs are included in the current period results.
(5)Our total equity-indexed compensation expense includes expense associated
with awards that will or may be settled in PAA common units and awards that will
or may be settled in cash. The awards that will or may be settled in PAA common
units are included in PAA's diluted net income per unit calculation when the
applicable performance criteria have been met. We consider the compensation
expense associated with these awards as a selected item impacting comparability
as the dilutive impact of the outstanding awards is included in PAA's diluted
net income per unit calculation, as applicable, and the majority of the awards
are expected to be settled in units. The portion of compensation expense
associated with awards that are certain to be settled in cash is not considered
a selected item impacting comparability. See Note 18 to our Consolidated
Financial Statements included in Part IV of our 2019 Annual Report on Form 10-K
for a comprehensive discussion regarding our equity-indexed compensation plans.
(6)During the periods presented, there were fluctuations in the value of CAD to
USD, resulting in the realization of foreign exchange gains and losses on the
settlement of foreign currency transactions as well as the revaluation of
monetary assets and liabilities denominated in a foreign currency. These gains
and losses are not integral to our core operating performance and were thus
classified as a selected item impacting comparability. See Note 10 to our
Condensed Consolidated Financial Statements for discussion regarding our
currency exchange rate risk hedging activities.
(7)Includes costs recognized during the period related to the Line 901 incident
that occurred in May 2015, net of amounts we believe are probable of recovery
from insurance. See Note 12 to our Condensed Consolidated Financial Statements
for additional information regarding the Line 901 incident.
(8)Includes acquisition-related expenses associated with the Felix Midstream
acquisition in February 2020. See Note 14 for additional information.
(9)Includes net gains recognized in connection with the PAA's repurchase of its
outstanding senior notes on the open market. See Note 8 to our Condensed
Consolidated Financial Statements for additional information.

(10)Other income/(expense), net per our Condensed Consolidated Statements of
Operations, adjusted for selected items impacting comparability ("Adjusted Other
income/(expense), net") is included in Adjusted EBITDA and excluded from Segment
Adjusted EBITDA.

Analysis of Operating Segments

We manage our operations through three operating segments: Transportation, Facilities and Supply and Logistics. Our CODM (our Chief Executive Officer) evaluates segment performance based on a variety of measures including Segment Adjusted EBITDA, segment volumes, Segment Adjusted EBITDA per barrel and maintenance capital investment.



We define Segment Adjusted EBITDA as revenues and equity earnings in
unconsolidated entities less (a) purchases and related costs, (b) field
operating costs and (c) segment general and administrative expenses, plus our
proportionate share of the depreciation and amortization expense of
unconsolidated entities, and further adjusted for certain selected items
including (i) the mark-to-market of derivative instruments that are related to
underlying activities in another period (or the reversal of such adjustments
from a prior period), gains and losses on derivatives that are related to
investing activities (such as the purchase of linefill) and inventory valuation
adjustments, as applicable, (ii) long-term inventory costing adjustments, (iii)
charges for obligations that are expected to be settled with the issuance of
equity instruments, (iv) amounts related to deficiencies associated with minimum
volume commitments, net of applicable amounts subsequently recognized into
revenue and (v) other items that our CODM believes are integral to understanding
our core segment operating performance. See Note 13 to our Condensed
Consolidated Financial Statements for a reconciliation of Segment Adjusted
EBITDA to Net income/(loss) attributable to PAGP.

Revenues and expenses from our Canadian based subsidiaries, which use CAD as
their functional currency, are translated at the prevailing average exchange
rates for the month.

Transportation Segment

Our Transportation segment operations generally consist of fee-based activities
associated with transporting crude oil and NGL on pipelines, gathering systems
and trucks. The Transportation segment generates revenue through a combination
of tariffs, pipeline capacity agreements and other transportation fees. Tariffs
and other fees on our pipeline systems vary by receipt point and delivery point.
The segment results generated by our tariff and other fee-related activities
depend on the volumes transported on the pipeline and the level of the tariff
and other fees charged, as well as the fixed and variable field costs of
operating the pipeline.

•Permian Basin region. The decrease in revenues, net of purchases and related
costs, of $64 million and $90 million for the three and nine months ended
September 30, 2020, respectively, compared to the same periods in 2019, was
primarily due to lower long-haul pipeline movements to Cushing and Corpus
Christi due to compressed regional basis differentials. Some shippers on the
pipelines to Cushing and Corpus Christi have under-delivered relative to their
minimum volume commitments; however, the earnings related to these volume
shortfalls will not be recognized until future periods when either the shortfall
is made up or when the shipper's make-up rights expire. Such deficiencies are
reflected as an "Adjustment" in the table above as discussed further below under
"-Adjustments: Deficiencies under minimum volume commitments, net." For the
nine-month comparative period, increased volumes from our gathering pipelines,
including the gathering system we acquired from Felix Midstream in February
2020, were more than offset by declines on our long-haul pipelines.

The increase in equity earnings over the comparative periods was primarily from
our 65% interest in the Cactus II pipeline, which was placed in service in
August 2019, partially offset by lower equity earnings from our 30% interest in
BridgeTex Pipeline Company, LLC primarily due to lower volumes.

•South Texas / Eagle Ford region. Equity earnings from our 50% interest in Eagle
Ford Pipeline LLC decreased for the three and nine months ended September 30,
2020 compared to the three and nine months ended September 30, 2019 due to a
combination of lower joint tariff volumes from the Permian Basin via our Cactus
I pipeline, and to a lesser extent, lower regional receipts.

•Central region. The decrease in revenues, net of purchases and related costs,
for the three and nine months ended September 30, 2020 compared to the same
periods in 2019 was primarily due to lower volumes as a result of (i) voluntary
curtailments and shut-ins by oil producers and (ii) a significant decrease in
drilling and completion

activity in the Mid-Continent, both factors are due to the low crude oil prices
during the current year. In addition, the production declines in this area, like
other areas in which we operate, has resulted in an increase in competition for
the remaining production in this region.

The decrease in equity earnings for the three and nine months ended September
30, 2020 compared to the same periods in 2019 was primarily due to the impact of
refinery downtime on certain of the demand pull pipelines out of Cushing,
Oklahoma, in which we own a 50% interest, as well as voluntary curtailments and
shut-ins by oil producers due to the low crude oil prices during the current
year.

•Rocky Mountain region. Equity earnings decreased for the three and nine months
ended September 30, 2020 compared to the same periods in 2019 primarily due to
(i) the sale of a 10% interest in Saddlehorn in February 2020 and (ii) lower
volumes of higher tariff crude oil movements, partially offset by new movements
of lower tariff NGL volumes on the pipelines owned by White Cliffs, in which we
own a 36% interest.

•Canada region. Revenues decreased for the three and nine months ended September
30, 2020 compared to the three and nine months ended September 30, 2019
primarily due to voluntary curtailments and shut-ins by oil producers due to the
low crude oil prices during the current year.

•Other regions, trucking and pipeline loss allowance revenue. The decrease in
other revenues, net of purchases and related costs, for the three and nine
months ended September 30, 2020 compared to the three and nine months ended
September 30, 2019 was primarily due to lower pipeline loss allowance revenue in
2020 due to lower prices and volumes. Additionally, volumes in our Gulf Coast
region were impacted by a decrease in throughput due to reduced refinery demand
on a lower tariff pipeline, which did not result in a significant impact on
revenue.

Adjustments: Deficiencies under minimum volume commitments, net. Many industry
infrastructure projects developed and completed over the last several years were
underpinned by long-term minimum volume commitment contracts whereby the shipper
agreed to either: (i) ship and pay for certain stated volumes or (ii) pay the
agreed upon price for a minimum contract quantity. Some of these agreements
include make-up rights if the minimum volume is not met. If a counterparty has a
make-up right associated with a deficiency, we bill the counterparty and defer
the revenue attributable to the counterparty's make-up right but record an
adjustment to reflect such amount associated with the current period activity in
Segment Adjusted EBITDA. We subsequently recognize the revenue, and record a
corresponding reversal of the adjustment, at the earlier of when the deficiency
volume is delivered or shipped, when the make-up right expires or when it is
determined that the counterparty's ability to utilize the make-up right is
remote.

For the three and nine months ended September 30, 2020, amounts billed to counterparties exceeded revenue recognized during the period that was previously deferred. For the three and nine months ended September 30, 2019, the recognition of previously deferred revenue exceeded amounts billed to counterparties associated with deficiencies under minimum volume commitments.



Field Operating Costs. The decrease in field operating costs for the three and
nine months ended September 30, 2020 compared to the same periods in 2019 was
primarily due to (i) a decrease in variable costs including reductions in
generator and power costs, the use of drag reducing agents and corrosion
inhibiting chemicals due to lower volumes, (ii) reductions in compensation
costs, including the benefit of wage subsidies received by our Canadian
subsidiary, and (iii) a decrease of maintenance and integrity management
activities, primarily due to interval changes facilitated through risk-based
data application, partially offset by (iv) higher property taxes due to assets
placed in service in 2020. In addition, the nine-month comparative period was
favorably impacted by (i) lower equity-based compensation costs on
liability-classified awards (which are not included as an "Adjustment" in the
table above) due to a decrease in PAA's common unit price and (ii) additional
estimated costs recognized in the second quarter of 2019 associated with the
Line 901 incident (which impact field operating costs but are excluded from
Segment Adjusted EBITDA and thus are reflected as an "Adjustment" in the table
above).

Segment General and Administrative Expenses. The decrease in segment general and
administrative expenses for the three and nine months ended September 30, 2020
compared to the same periods in 2019 was primarily due to lower equity-based
compensation costs on liability-classified awards (which are not included as an
"Adjustment" in the table above), due to a decrease in PAA's common unit price,
and lower compensation costs including the benefit of wage subsidies received by
our Canadian subsidiary.

Maintenance Capital. Maintenance capital consists of capital expenditures for
the replacement and/or refurbishment of partially or fully depreciated assets in
order to maintain the operating and/or earnings capacity of our existing assets.
The decrease in maintenance capital spending for the three and nine months ended
September 30, 2020 compared to the same periods in 2019 was primarily due to
interval changes facilitated through risk-based data application to integrity
management activities.

Facilities Segment

Our Facilities segment operations generally consist of fee-based activities
associated with providing storage, terminalling and throughput services
primarily for crude oil, NGL and natural gas, as well as NGL fractionation and
isomerization services and natural gas and condensate processing services. The
Facilities segment generates revenue through a combination of month-to-month and
multi-year agreements.

The following tables set forth our operating results from our Facilities

The following is a discussion of items impacting Facilities segment operating results.

Revenues, Purchases and Related Costs and Volumes. Variances in revenues and average monthly volumes were primarily driven by the following:



•Crude Oil Storage. Revenues from our crude oil storage operations increased by
$13 million and $28 million for the three and nine months ended September 30,
2020 compared to three and nine months ended September 30, 2019, respectively,
primarily due to (i) the addition of an aggregate of 3.1 million barrels of
storage capacity at our Cushing, St. James and Midland terminals, (ii) increased
activity at our Cushing and Midland terminals and (iii) increased spot activity
at certain of our West Coast terminals.

The increase in equity earnings over the comparative periods was from our 50%
interest in Eagle Ford Terminals, which owns a crude oil storage facility in
Corpus Christi that was placed in service in September of 2019.

•Rail Terminals. Revenues from our rail terminals decreased by $13 million and
$29 million for the three and nine months ended September 30, 2020 compared to
three and nine months ended September 30, 2019, respectively, primarily due to
decreased activity at certain of our rail terminals as a result of lower volumes
due to voluntary shut-ins and curtailments, as well as less favorable market
conditions.

•NGL Operations. Revenues from our NGL operations decreased by $18 million and
$12 million for the three and nine months ended September 30, 2020 compared to
the same periods in 2019, respectively, primarily due to the sale of certain NGL
terminals in the fourth quarter of 2019 and the second quarter of 2020 and net
unfavorable foreign exchange impacts of approximately $1 million and $7 million,
respectively. The three and nine month comparative periods were further
unfavorably impacted by lower revenues from our NGL processing facilities. The
decrease in revenues for the nine months ended September 30, 2020 compared to
the nine months ended September 30, 2019 was partially offset by the favorable
impact of the receipt of a deficiency payment of approximately $20 million upon
the expiration of a multi-year contract.

•Natural Gas and Condensate Processing. Revenues, net of purchases and related
costs, from our natural gas and condensate processing operations decreased by $9
million for nine months ended September 30, 2020 compared to the same period in
2019 primarily due to the unfavorable impact of a $5 million payment to resolve
a contractual dispute as well as a decrease in condensate processing volumes and
rates.

Field Operating Costs. The decrease in field operating costs for the three and
nine months ended September 30, 2020 compared to the same periods in 2019 was
primarily due to (i) lower integrity management and maintenance activities due
to interval changes facilitated through risk-based data application, (ii)
reduced activity at our rail terminals and (iii) reductions in compensation
costs including the benefit of wage subsidies received by our Canadian
subsidiary. In addition, the three-month comparative period was favorably
impacted by mark-to-market gains in the current period on fuel hedges (which
impacts field operating costs but are excluded from Segment Adjusted EBITDA and
thus are reflected as an "Adjustment" in the table above), and the nine-month
comparative period was favorably impacted by lower insurance claims costs.

Segment General and Administrative Expenses. The decrease in segment general and
administrative expenses for the three months ended September 30, 2020 compared
to the same period in 2019 was primarily driven by lower compensation costs
including the benefit of wage subsidies received by our Canadian subsidiary.

Maintenance Capital. The decrease in maintenance capital spending for the three
and nine months ended September 30, 2020 compared to the same periods in 2019
was primarily due to interval changes facilitated through risk-based data
application to integrity management activities.

Supply and Logistics Segment



Revenues from our Supply and Logistics segment activities reflect the sale of
gathered and bulk-purchased crude oil, as well as sales of NGL volumes.
Generally, our segment results are impacted by (i) increases or decreases in our
Supply and Logistics segment volumes (which consist of lease gathering crude oil
purchases volumes and NGL sales volumes), (ii) the overall strength, weakness
and volatility of market conditions, including regional differentials, and
(iii) the effects of competition on our lease gathering and NGL margins. In
addition, the execution of our risk management strategies in conjunction with
our assets can provide upside in certain markets.

The following tables set forth our operating results from our Supply and
Logistics segment:

Our crude oil and NGL supply, logistics and distribution operations are not
directly affected by the absolute level of prices. Because the commodities that
we buy and sell are generally indexed to the same pricing indices for both sales
and purchases, revenues and costs related to purchases will fluctuate with
market prices. However, the margins related to those sales and purchases will
not necessarily have a corresponding increase or decrease. Additionally, net
revenues are impacted by net gains and losses from certain derivative activities
during the periods.

Our NGL operations are sensitive to weather-related demand, particularly during
the approximate five-month peak heating season of November through March, and
temperature differences from period-to-period may have a significant effect on
NGL demand and thus our financial performance.

Segment Adjusted EBITDA and Volumes. The following summarizes the significant items impacting our Supply and Logistics Segment Adjusted EBITDA:



•Crude Oil Operations. Revenues, net of purchases and related costs, ("net
revenues") from our crude oil operations decreased for the three and nine months
ended September 30, 2020 compared to the three and nine months ended September
30, 2019, primarily due to a combination of (i) less favorable market
conditions, (ii) the impact of lower volumes in higher margin areas, partially
offset by volume increases in lower margin areas, and (iii) the impact of
weighted average inventory costing resulting in lower margins during the period
(which will result in higher margins in subsequent periods), partially offset by
the favorable impact of contango market conditions during the second and third
quarters of 2020.

•NGL Operations. Net revenues from our NGL operations decreased for the three
and nine months ended September 30, 2020 compared to the three and nine months
ended September 30, 2019, primarily due to weaker fractionation spreads, lower
border flows through our straddle plants and the decision to decrease shoulder
month sales volumes and increase winter month sales volumes, as well as the
absence of the favorable impact from certain non-recurring items recorded in the
second quarter of 2019.

•Impact from Certain Derivative Activities Net of Inventory Valuation
Adjustments. The impact from certain derivative activities on our net revenues
includes mark-to-market and other gains and losses resulting from certain
derivative instruments that are related to underlying activities in another
period (or the reversal of mark-to-market gains and losses from a prior period),
losses on derivatives that are related to investing activities (such as the
purchase of linefill) and inventory valuation adjustments, as applicable. See
Note 10 to our Condensed Consolidated Financial Statements for a comprehensive
discussion regarding our derivatives and risk management activities. These gains
and losses impact our net revenues but are excluded from Segment Adjusted EBITDA
and thus are reflected as an "Adjustment" in the table above.
                                       57

--------------------------------------------------------------------------------

Table of Contents



•Long-Term Inventory Costing Adjustments. Our net revenues are impacted by
changes in the weighted average cost of our crude oil and NGL inventory pools
that result from price movements during the periods. These costing adjustments
related to long-term inventory necessary to meet our minimum inventory
requirements in third-party assets and other working inventory that was needed
for our commercial operations. We consider this inventory necessary to conduct
our operations and we intend to carry this inventory for the foreseeable future.
These costing adjustments impact our net revenues but are excluded from Segment
Adjusted EBITDA and thus are reflected as an "Adjustment" in the table above.

•Foreign Exchange Impacts. Our net revenues are impacted by fluctuations in the
value of CAD to USD, which result in the realization of foreign exchange gains
and losses on the settlement of foreign currency transactions as well as the
revaluation of monetary assets and liabilities denominated in a foreign
currency. These gains and losses impact our net revenues but are excluded from
Segment Adjusted EBITDA and thus are reflected as an "Adjustment" in the table
above.

•Field Operating Costs. The decrease in field operating costs for the three and
nine months ended September 30, 2020 compared to the same periods in 2019 was
primarily driven by a decrease in long-haul third-party trucking costs and a
decrease in company personnel and truck costs as additional pipeline capacity
came into service after the first half of 2019.

•Segment General and Administrative Expenses. The decrease in segment general
and administrative expenses for the three and nine months ended September 30,
2020 compared to the same periods in 2019 was primarily driven by lower
compensation costs including the benefit of wage subsidies received by our
Canadian subsidiary and decreased travel and entertainment costs. The nine-month
comparative period was further favorably impacted by a decrease in equity-based
compensation costs on liability-classified awards (which are not included as an
"Adjustment" in the table above) due to a decrease in PAA's common unit price.

Maintenance Capital. The decrease in maintenance capital spending for the three
months ended September 30, 2020 compared to the same period in 2019 was due to
lower tractor trailer lease buyouts.

Other Income and Expenses

Depreciation and Amortization



Depreciation and amortization expense increased for the three and nine months
ended September 30, 2020 compared to the three and nine months ended September
30, 2019 largely driven by additional depreciation expense associated with
acquired assets and the completion of various investment capital projects. In
addition, the increase for the nine-month comparative period was also impacted
by a reduction in the useful lives of certain assets.

Gains/Losses on Asset Sales and Asset Impairments, Net



The net loss on asset sales and asset impairments for the nine months ended
September 30, 2020 was largely driven by (i) non-cash impairment losses of
approximately $446 million related to the write-down of certain pipeline and
other long-lived assets due to the current macroeconomic and geopolitical
conditions including the collapse of oil prices driven by both the decrease in
demand caused by the COVID-19 pandemic and excess supply, as well as changing
market conditions and expected lower crude oil production in certain regions,
and (ii) approximately $167 million of impairment losses recognized on assets
upon classification as held for sale. See Note 14 for additional information
regarding these asset impairments.

Goodwill Impairment Losses

During the first quarter of 2020, we recognized a goodwill impairment charge of
$2.5 billion, representing the entire balance of goodwill. See Note 6 to our
Condensed Consolidated Financial Statements for additional information.

Gain on/(Impairment of) Investments in Unconsolidated Entities, Net



During the three and nine months ended September 30, 2020, we recognized losses
of $91 million and $202 million, respectively, related to the write-down of
certain of our investments in unconsolidated entities. Additionally, during the
nine months ended September 30, 2020, we recognized a gain of $21 million
related to our sale of a 10% interest in Saddlehorn Pipeline Company, LLC. See
Note 7 to our Condensed Consolidated Financial Statements for additional
information. During the nine months ended September 30, 2019, we recognized a
non-cash gain of $269 million related to a fair value adjustment resulting from
the accounting for the contribution of our undivided joint interest in the
Capline pipeline system for an equity interest in Capline Pipeline Company LLC.

Interest Expense



The increase in interest expense for the three and nine months ended September
30, 2020 compared to the three and nine months ended September 30, 2019 was
primarily due to a higher weighted average debt balance during the 2020 period,
partially offset by lower weighted average rates. In addition, the nine-month
comparative period was further unfavorably impacted by lower capitalized
interest for the nine months ended September 30, 2020 driven by fewer capital
projects under construction.

(2)The activity in 2020 was primarily related to the impact from the change in
the United States dollar to Canadian dollar exchange rate on the portion of our
intercompany net investment that is not long-term in nature.

Income Tax (Expense)/Benefit



The decrease in income tax expense for the three months ended September 30, 2020
compared to the three months ended September 30, 2019 and the increase in the
income tax benefit for the nine months ended September 30, 2020 compared to the
nine months ended September 30, 2019 was primarily due to the impact of lower
earnings at PAA, including goodwill impairment losses for the nine months ended
September 30, 2020, on income attributable to PAGP.

Liquidity and Capital Resources

General



On a consolidated basis, our primary sources of liquidity are (i) cash flow from
operating activities, (ii) borrowings under PAA's credit facilities or the PAA
commercial paper program and (iii) funds received from sales of equity and debt
securities. In addition, we may supplement these sources of liquidity with
proceeds from our divestiture program, as further discussed below in the section
entitled "-Acquisitions and Capital Expenditures." Our primary cash requirements
include, but are not limited to, (i) ordinary course of business uses, such as
the payment of amounts related to the purchase of crude oil, NGL and other
products, other expenses and interest payments on outstanding debt,
(ii) investment and maintenance capital activities, (iii) acquisitions of assets
or businesses, (iv) repayment of principal on long-term debt and
(v) distributions to our Class A shareholders and noncontrolling interests. We
generally expect to fund our short-term cash requirements through cash flow
generated from operating activities and/or borrowings under the PAA commercial
paper program or PAA's credit facilities. In addition, we generally expect to
fund our long-term needs, such as those resulting from investment capital
activities or acquisitions and refinancing long-term debt, through a variety of
sources (either separately or in combination), which may include the sources
mentioned above as funding for short-term needs and/or the issuance of
additional equity or debt securities and the sale of assets.

As of September 30, 2020, although we had a working capital deficit of $398
million, we had approximately $2.8 billion of liquidity available to meet our
ongoing operating, investing and financing needs, subject to continued covenant
compliance, as noted below (in millions):

(2)Available capacity under the PAA senior unsecured revolving credit facility
and the PAA senior secured hedged inventory facility was reduced by outstanding
letters of credit of $96 million and $44 million, respectively.

On November 3, 2020, PAA repaid its $600 million, 5.00% senior notes due
February 2021 at par and used borrowings under the PAA commercial paper program
and cash on hand for the repayment. See further discussion in "Equity and Debt
Financing Activities" below.

Current macroeconomic and geopolitical conditions including the collapse of oil
prices driven by both the decrease in demand caused by the COVID-19 pandemic and
excess supply has caused liquidity issues impacting many energy companies;
however, we believe that we have, and will continue to have, the ability to
access the PAA commercial paper program and credit facilities, which we use to
meet our short-term cash needs. We believe that our financial position remains
strong and we have sufficient liquidity; however, extended disruptions in the
financial markets and/or energy price volatility that adversely affect our
business may have a materially adverse effect on our financial condition,
results of operations or cash flows. In addition, usage of the PAA credit
facilities, which provide the financial backstop for the PAA commercial paper
program, is subject to ongoing compliance with covenants. As of September 30,
2020, PAA was in compliance with all such covenants. Also, see Item 1A. "Risk
Factors" included in our 2019 Annual Report on Form 10-K and Item 1A. "Risk
Factors" in Part II of our Quarterly Report on Form 10-Q for the quarter ended
March 31, 2020 for further discussion regarding such risks that may impact our
liquidity and capital resources.

Cash Flow from Operating Activities

For a comprehensive discussion of the primary drivers of cash flow from operating activities, including the impact of varying market conditions and the timing of settlement of our derivatives, see Item 7. "Liquidity and Capital Resources-Cash Flow from Operating Activities" included in our 2019 Annual Report on Form 10-K.



Net cash provided by operating activities for the first nine months of 2020 and
2019 was $1.253 billion and $1.774 billion, respectively, and primarily resulted
from earnings from our operations. Additionally, as discussed further below,
changes during these periods in our inventory levels and associated margin
balances required as part of our hedging activities impacted our cash flow from
operating activities.

During the nine months ended September 30, 2020, we increased the volume of both
our crude oil inventory to be stored during the contango market and our NGL
inventory in anticipation of the 2020-2021 heating season as well as the margin
balances required as part of our hedging activities, all of which was funded by
short-term debt. The cash outflows associated with these activities were
partially offset by lower prices for inventory purchased and stored at the end
of the current period compared to the end of 2019.

During the nine months ended September 30, 2019, our cash provided by operating
activities was positively impacted by the proceeds from the sale of inventory
that we held, primarily due to the sale of NGL inventory. The favorable effects
from the liquidation of such inventory were partially offset by the timing of
revenue recognized during the period for which cash was received in prior
periods.

Acquisitions and Capital Expenditures



In addition to our operating needs discussed above, on a consolidated basis, we
also use cash for our acquisition activities and investment capital projects and
maintenance capital activities. Historically, we have financed these
expenditures primarily with cash generated by operating activities and the
financing activities discussed in "-Equity and Debt Financing Activities" below.
In recent years, we have also used proceeds from our divestiture program. We
have made and will continue to make capital expenditures for acquisitions,
investment capital projects and maintenance activities. However, in the near
term we do not plan to issue common equity to fund such activities.

Acquisitions. In February 2020, we acquired a crude oil gathering system and
related assets in the Delaware Basin for approximately $300 million. See Note 14
to our Condensed Consolidated Financial Statements for additional information.

Capital Projects. We invested $785 million in midstream infrastructure during
the nine months ended September 30, 2020, and we expect to invest approximately
$950 million during the full year ending December 31, 2020. Our expected capital
investment for 2020 reflects a reduction from our expected capital investment at
year-end 2019 due to the current dynamic and uncertain market conditions. See
"-Acquisitions and Capital Projects" for additional information. We expect to
fund our 2020 capital program with retained cash flow, proceeds from assets sold
as part of our divestiture program or debt.

Divestitures. In January 2020, we signed a definitive agreement to sell certain
of our LA Basin crude oil terminals. This transaction closed in the fourth
quarter of 2020 for proceeds of approximately $200 million, subject to certain
adjustments. This transaction closed in the fourth quarter of 2020. In April
2020, we sold certain NGL terminals for $163 million, subject to certain
adjustments. See Note 14 to our Condensed Consolidated Financial Statements for
additional information. Additionally, we sold a 10% ownership interest in
Saddlehorn Pipeline Company, LLC for proceeds of approximately $78 million. See
Note 7 to our Condensed Consolidated Financial Statements for additional
information.

Ongoing Acquisition, Divestiture and Investment Activities. We intend to
continue to focus on activities to enhance investment returns and reinforce
capital discipline through asset optimization, joint ventures, potential
divestitures and similar arrangements. We typically do not announce a
transaction until after we have executed a definitive agreement. However, in
certain cases in order to protect our business interests or for other reasons,
we may defer public announcement of a transaction until closing or a later date.
Past experience has demonstrated that discussions and negotiations regarding a
potential transaction can advance or terminate in a short period of time.
Moreover, the closing of any transaction for which we have entered into a
definitive agreement may be subject to customary and other closing conditions,
which may not ultimately be satisfied or waived. Accordingly, we can give no
assurance that our current or future acquisition or investment efforts will be
successful, or that our strategic asset divestitures will be completed. Although
we expect the acquisitions and investments we make to be accretive in the long
term, we can provide no assurance that our expectations will ultimately be
realized. Also, see Item 1A. "Risk Factors-Risks Related to PAA's Business" of
our 2019 Annual Report on Form 10-K for further discussion regarding risks
related to our acquisitions and divestitures.

Equity and Debt Financing Activities



On a consolidated basis, our financing activities primarily relate to funding
investment capital projects, acquisitions and refinancing of debt maturities, as
well as short-term working capital (including borrowings for NYMEX and ICE
margin deposits) and hedged inventory borrowings related to our NGL business and
contango market activities. Our financing activities have primarily consisted of
equity offerings, PAA senior notes offerings and borrowings and repayments under
the credit facilities or the PAA commercial paper program and other debt
agreements, as well as payment of distributions to our Class A shareholders and
noncontrolling interests.

PAGP Registration Statements. We have filed with the SEC a shelf registration
statement that, subject to effectiveness at the time of use, allows us to issue
up to an aggregate of $1.0 billion of equity securities (the "PAGP Traditional
Shelf"). At September 30, 2020, we had approximately $939 million of unsold
securities available under the PAGP Traditional Shelf. We also have access to a
shelf registration statement (the "PAGP WKSI Shelf"), which provides us with the
ability to offer and sell an unlimited amount of equity securities, subject to
market conditions and capital needs. We did not conduct any offerings under the
PAGP Traditional Shelf or the PAGP WKSI Shelf during the nine months ended
September 30, 2020.

PAA Registration Statements. PAA periodically accesses the capital markets for
both equity and debt financing. PAA has filed with the SEC a universal shelf
registration statement that, subject to effectiveness at the time of use, allows
PAA to issue up to an aggregate of $1.1 billion of debt or equity securities
(the "PAA Traditional Shelf"). At September 30, 2020, PAA had approximately $1.1
billion of unsold securities available under the PAA Traditional Shelf. PAA did
not conduct any offerings under the PAA Traditional Shelf during the nine months
ended September 30, 2020. PAA also has access to a universal shelf registration
statement (the "PAA WKSI Shelf"), which provides it with the ability to offer
and sell an unlimited amount of debt and equity securities, subject to market
conditions and capital needs. The offering of PAA's $750 million, 3.80% senior
notes in June 2020 was conducted under the PAA WKSI Shelf.

Credit Agreements, Commercial Paper Program and Indentures. The credit
agreements for the PAA revolving credit facilities (which impact PAA's ability
to access the PAA commercial paper program because they provide the financial
backstop that supports PAA's short-term credit ratings) and its GO Zone term
loans and the indentures governing its senior notes contain cross-default
provisions. A default under PAA's credit agreements or indentures would permit
the lenders to accelerate the maturity of the outstanding debt. As long as PAA
is in compliance with the provisions in its credit agreements, its ability to
make distributions of available cash is not restricted. As of September 30,
2020, PAA was in compliance with the covenants contained in its credit
agreements and indentures.

During the nine months ended September 30, 2020, we had net repayments on PAA's
credit facilities and commercial paper program of $306 million. The net
repayments resulted primarily from cash flow from operating activities, proceeds
from asset sales and the issuance of PAA's $750 million, 3.80% senior notes in
June 2020, which offset borrowings during the period related to funding needs
for capital investments, inventory purchases and other general partnership
purposes.

As of September 30, 2019 and December 31, 2018, we had no outstanding borrowings
under the PAA credit agreements or commercial paper program. However, during the
nine months ended September 30, 2019, we borrowed and repaid $10.5 billion under
the PAA credit facilities and commercial paper program. These repayments
resulted primarily from cash flow from operating activities and proceeds from
PAA senior notes issuances.

  Table of Contents
In June 2020, PAA completed the offering of $750 million, 3.80% senior notes due
September 2030 at a public offering price of 99.794%. Interest payments are due
on March 15 and September 15 of each year, commencing on September 15, 2020. We
used the net proceeds from this offering of $742 million, after deducting the
underwriting discount and offering expenses, primarily to repay the principal
amounts of PAA's 5.00% senior notes due February 2021 (which were redeemed on
November 3, 2020). Prior to such repayment, we used a portion of the proceeds to
repay outstanding borrowings under PAA's commercial paper program and credit
facilities and for general partnership purposes.

On November 3, 2020, PAA redeemed its $600 million, 5.00% senior notes due February 2021.

Distributions to Our Class A Shareholders



Distributions to our Class A shareholders. We distribute all of our available
cash within 55 days following the end of each quarter to Class A shareholders of
record. Available cash is generally defined as all of our cash and cash
equivalents on hand at the end of each quarter less reserves established in the
discretion of our general partner for future requirements. Our levels of
financial reserves are established by our general partner and include reserves
for the proper conduct of our business (including future capital expenditures
and anticipated credit needs), compliance with law or contractual obligations
and funding of future distributions to our shareholders. On November 13, 2020,
we will pay a quarterly distribution of $0.18 per Class A share ($0.72 per Class
A share on an annualized basis), which is unchanged from our prior quarterly
distribution, but equates to a reduction of 50% compared to the quarterly
distribution of $0.36 per Class A share ($1.44 per Class A share on an
annualized basis) paid in February 2020. This reduction was made in response to
the current dynamic and uncertain market conditions to further reinforce our
commitment to maintaining a solid capital structure and strong liquidity. See
"-Executive Summary -Recent Events & Outlook" for further discussion. See Note 9
to our Condensed Consolidated Financial Statements for details of distributions
paid during or pertaining to the first nine months of 2020. Also, see Item 5.
"Market for Registrant's Shares, Related Shareholder Matters and Issuer
Purchases of Equity Securities-Cash Distribution Policy" included in our 2019
Annual Report on Form 10-K for additional discussion regarding distributions.

Distributions to Noncontrolling Interests



Distributions to noncontrolling interests represent amounts paid on interests in
consolidated entities that are not owned by us. As of September 30, 2020,
noncontrolling interests in our subsidiaries consisted of (i) limited partner
interests in PAA including a 69% interest in PAA's common units and PAA's Series
A preferred units combined and 100% of PAA's Series B preferred units, (ii) an
approximate 23% limited partner interest in AAP and (iii) a 33% interest in Red
River LLC. See Note 9 to our Condensed Consolidated Financial Statements for
additional information.

Distributions to PAA's Series A preferred unitholders. On November 13, 2020, PAA
will pay a cash distribution of $37 million ($0.525 per unit) on its Series A
preferred units outstanding as of October 30, 2020, the record date for such
distribution for the period from July 1, 2020 through September 30, 2020. See
Note 9 to our Condensed Consolidated Financial Statements for details of
distributions made during or pertaining to the first nine months of 2020.

Distributions to PAA's Series B preferred unitholders. Distributions on PAA's
Series B preferred units are payable in cash semi-annually in arrears on the
15th day of May and November. On November 16, 2020, PAA will pay the semi-annual
cash distribution of $24.5 million on its Series B preferred units to holders of
record at the close of business on November 2, 2020 for the period from May 15,
2020 to November 14, 2020. See Note 9 to our Condensed Consolidated Financial
Statements for additional information.

Distributions to PAA's common unitholders. On November 13, 2020, PAA will pay a
quarterly distribution of $0.18 per common unit ($0.72 per common unit on an
annualized basis). See Note 9 to our Condensed Consolidated Financial Statements
for details of distributions paid during or pertaining to the first nine months
of 2020.

We believe that we have sufficient liquid assets, cash flow from operating
activities and borrowing capacity under the credit agreements to meet our
financial commitments, debt service obligations, contingencies and anticipated
capital expenditures. We are, however, subject to business and operational risks
that could adversely affect our cash flow. A prolonged material decrease in our
cash flows would likely produce an adverse effect on our borrowing capacity and
cost of borrowing.

Contingencies

For a discussion of contingencies that may impact us, see Note 12 to our Condensed Consolidated Financial Statements.

Commitments



Contractual Obligations. In the ordinary course of doing business, we purchase
crude oil and NGL from third parties under contracts, the majority of which
range in term from thirty-day evergreen to five years, with a limited number of
contracts with remaining terms extending up to 13 years. We establish a margin
for these purchases by entering into various types of physical and financial
sale and exchange transactions through which we seek to maintain a position that
is substantially balanced between purchases on the one hand and sales and future
delivery obligations on the other. The table below includes purchase obligations
related to these activities. Where applicable, the amounts presented represent
the net obligations associated with our counterparties (including giving effect
to netting buy/sell contracts and those subject to a net settlement
arrangement). We do not expect to use a significant amount of internal capital
to meet these obligations, as the obligations will be funded by corresponding
sales to entities that we deem creditworthy or who have provided credit support
we consider adequate.

The following table includes our best estimate of the amount and timing of these payments as well as other amounts due under the specified contractual obligations as of September 30, 2020 (in millions):



                                     Remainder of                                                                               2025 and

(1)Includes debt service payments, interest payments due on PAA's senior notes
and the commitment fee on assumed available capacity under the PAA credit
facilities, as well as long-term borrowings under the PAA credit agreements and
the PAA commercial paper program, if any. Although there may be short-term
borrowings under the PAA credit agreements and the PAA commercial paper program,
we historically repay and borrow at varying amounts. As such, we have included
only the maximum commitment fee (as if no short-term borrowings were outstanding
on the PAA credit agreements or the PAA commercial paper program) in the amounts
above. For additional information regarding PAA's debt obligations, see Note 8
to our Condensed Consolidated Financial Statements.
(2)Includes both operating and finance leases as defined by FASB guidance.
Leases are primarily for (i) railcars, (ii) office space, (iii), land, (iv)
vehicles, (v) storage tanks and (vi) tractor trailers. See Note 14 to our
Consolidated Financial Statements included in Part IV of our 2019 Annual Report
on Form 10-K for additional information.
(3)Includes (i) other long-term liabilities, (ii) storage, processing and
transportation agreements (including certain agreements for which the amount and
timing of expected payments is subject to the completion of underlying
construction projects), (iii) certain rights-of-way easements and
(iv) noncancelable commitments related to our investment capital projects,
including projected contributions for our share of the capital spending of our
equity method investments. The storage, processing and transportation agreements
include approximately $2.0 billion associated with agreements to store and
transport crude oil at posted tariff rates on pipelines or at facilities that
are owned by equity method investees. A portion of our commitment to transport
is supported by crude oil buy/sell or other agreements with third parties with
commensurate quantities.
(4)Amounts are primarily based on estimated volumes and market prices based on
average activity during September 2020. The actual physical volume purchased and
actual settlement prices will vary from the assumptions used in the table.
Uncertainties involved in these estimates include levels of production at the
wellhead, weather conditions, changes in market prices and other conditions
beyond our control.

Letters of Credit. In connection with supply and logistics activities, we
provide certain suppliers with irrevocable standby letters of credit to secure
our obligation for the purchase and transportation of crude oil, NGL and natural
gas. Additionally, we issue letters of credit to support insurance programs,
derivative transactions, including hedging-related margin obligations, and
construction activities. At September 30, 2020 and December 31, 2019, we had
outstanding letters of credit of approximately $140 million and $157 million,
respectively.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements as defined by Item 303 of Regulation S-K.

                           FORWARD-LOOKING STATEMENTS

All statements included in this report, other than statements of historical
fact, are forward-looking statements, including but not limited to statements
incorporating the words "anticipate," "believe," "estimate," "expect," "plan,"
"intend" and "forecast," as well as similar expressions and statements regarding
our business strategy, plans and objectives for future operations. The absence
of such words, expressions or statements, however, does not mean that the
statements are not forward-looking. Any such forward-looking statements reflect
our current views with respect to future events, based on what we believe to be
reasonable assumptions. Certain factors could cause actual results or outcomes
to differ materially from the results or outcomes anticipated in the
forward-looking statements. The most important of these factors include, but are
not limited to:

Factors Related Primarily to the COVID-19 Pandemic and Excess Supply Situation:



•further declines in global crude oil demand and crude oil prices that
correspondingly lead to a significant reduction of domestic crude oil, NGL and
natural gas production (whether due to reduced producer cash flow to fund
drilling activities or the inability of producers to access capital, or both,
the unavailability of pipeline and/or storage capacity, the shutting-in of
production by producers, government-mandated pro-ration orders, or other
factors), which in turn could result in significant declines in the actual or
expected volume of crude oil and NGL shipped, processed, purchased, stored,
fractionated and/or gathered at or through the use of our assets and/or the
reduction of commercial opportunities that might otherwise be available to us;

•uncertainty regarding the length of time it will take for the United States,
Canada, and the rest of the world to contain the spread of the COVID-19 virus to
the point where restrictions on various commercial and economic activities are
(or remain) lifted and the extent to which consumer demand and demand for crude
oil rebound in the future;

•uncertainty regarding the future actions of foreign oil producers such as Saudi Arabia and Russia and the risk that they take actions that will prolong or exacerbate the current over-supply of crude oil;



•uncertainty regarding the timing, pace and extent of an economic recovery in
the United States and elsewhere, which in turn will likely affect demand for
crude oil and therefore the demand for the midstream services we provide and the
commercial opportunities available to us;

•the effect of an overhang of significant amounts of crude oil inventory stored
in the United States and elsewhere and the impact that such inventory overhang
ultimately has on the timing of a return to market conditions that are more
conducive to an increase in drilling and production activities in the United
States and a resulting increase in demand for the midstream services we provide;

•the refusal or inability of our customers or counterparties to perform their
obligations under their contracts with us (including commercial contracts, asset
sale agreements and other agreements), whether justified or not and
                                       65
--------------------------------------------------------------------------------
  Table of Contents
whether due to financial constraints (reduced creditworthiness, liquidity issues
or insolvency), market constraints, legal constraints (including governmental
orders or guidance), the exercise of contractual or common law rights that
allegedly excuse their performance (such as force majeure or similar claims) or
other factors;

•our inability to perform our obligations under our contracts, whether due to
non-performance by third parties, including our customers or counterparties,
market constraints, third-party constraints, legal constraints (including
governmental orders or guidance), or other factors;

•operational difficulties due to physical distancing restrictions and the additional demands such restrictions may place on our employees;

•disruptions to futures markets for crude oil, NGL and other petroleum products, which may impair our ability to execute our commercial and hedging strategies;

•our inability to reduce capital expenditures to the extent forecasted, whether due to the incurrence of unexpected or unplanned expenditures, third-party claims or other factors;

•the inability to complete forecasted asset sale transactions due to governmental action, litigation, counterparty non-performance or other factors;

General Factors:

•our ability to pay distributions to our Class A shareholders;

•our expected receipt of, and amounts of, distributions from Plains AAP, L.P.;

•the effects of competition, including the effects of capacity overbuild in areas where we operate;



•negative societal sentiment regarding the hydrocarbon energy industry and the
continued development and consumption of hydrocarbons, which could influence
consumer preferences and governmental or regulatory actions in ways that
adversely impact our business;

•unanticipated changes in crude oil and NGL market structure, grade differentials and volatility (or lack thereof);

•environmental liabilities or events that are not covered by an indemnity, insurance or existing reserves;



•fluctuations in refinery capacity in areas supplied by our mainlines and other
factors affecting demand for various grades of crude oil, NGL and natural gas
and resulting changes in pricing conditions or transportation throughput
requirements;

•maintenance of PAA's credit rating and ability to receive open credit from suppliers and trade counterparties;



•the occurrence of a natural disaster, catastrophe, terrorist attack (including
eco-terrorist attacks) or other event, including cyber or other attacks on our
electronic and computer systems;

•the successful integration and future performance of acquired assets or businesses and the successful operation of joint ventures and joint operating arrangements we enter into from time to time, whether relating to assets operated by us or by third parties;



•failure to implement or capitalize, or delays in implementing or capitalizing,
on investment capital projects, whether due to permitting delays, permitting
withdrawals or other factors;

•shortages or cost increases of supplies, materials or labor;

•the impact of current and future laws, rulings, governmental regulations, accounting standards and statements, and related interpretations, including legislation or regulatory initiatives that prohibit, restrict or regulate hydraulic fracturing;


                                       66

  Table of Contents
•tightened capital markets or other factors that increase our cost of capital or
limit our ability to obtain debt or equity financing on satisfactory terms to
fund additional acquisitions, investment capital projects, working capital
requirements and the repayment or refinancing of indebtedness;

•general economic, market or business conditions (both within the United States
and globally and including the potential for a recession or significant slowdown
in economic activity levels) and the amplification of other risks caused by
volatile financial markets, capital constraints and liquidity concerns;

•the availability of, and our ability to consummate, divestitures, joint ventures, acquisitions or other strategic opportunities;

•the currency exchange rate of the Canadian dollar;

•continued creditworthiness of, and performance by, our counterparties, including financial institutions and trading companies with which we do business;



•inability to recognize current revenue attributable to deficiency payments
received from customers who fail to ship or move more than minimum contracted
volumes until the related credits expire or are used;

•non-utilization of our assets and facilities;

•increased costs, or lack of availability, of insurance;

•weather interference with business operations or project construction, including the impact of extreme weather events or conditions;

•the effectiveness of our risk management activities;

•fluctuations in the debt and equity markets, including the price of PAA's units at the time of vesting under its long-term incentive plans;

•risks related to the development and operation of our assets, including our ability to satisfy our contractual obligations to our customers; and



•other factors and uncertainties inherent in the transportation, storage,
terminalling and marketing of crude oil, as well as in the storage of natural
gas and the processing, transportation, fractionation, storage and marketing of
natural gas liquids.

Other factors described herein, as well as factors that are unknown or
unpredictable, could also have a material adverse effect on future results.
Please read "Risk Factors" discussed in Item 1A of our 2019 Annual Report on
Form 10-K and in Part II of our Quarterly Report on Form 10-Q for the quarter
ended March 31, 2020. Except as required by applicable securities laws, we do
not intend to update these forward-looking statements and information.
