Introduction
The following discussion is intended to provide investors with an understanding of our financial condition and results of our operations and should be read in conjunction with our historical Consolidated Financial Statements and accompanying notes and Management's Discussion and Analysis of Financial Condition and Results of Operations as presented in our 2020 Annual Report on Form 10-K. For more detailed information regarding the basis of presentation for the following financial information, see the Condensed Consolidated Financial Statements and related notes that are contained in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Our discussion and analysis includes the following:
•Executive Summary •Results of Operations •Liquidity and Capital Resources •Off-Balance Sheet Arrangements •Recent Accounting Pronouncements •Critical Accounting Policies and Estimates •Forward-Looking Statements Executive Summary Company Overview We are aDelaware limited partnership formed onJuly 17, 2013 that has elected to be taxed as a corporation forUnited States federal income tax purposes. As ofJune 30, 2021 , our sole cash-generating assets consisted of (i) a 100% managing member interest inPlains All American GP LLC ("GP LLC ") that has also elected to be taxed as a corporation forUnited States federal income tax purposes and (ii) an approximate 79% limited partner interest in AAP through our direct ownership of approximately 193.1 million AAP units and indirect ownership of approximately 1.0 million AAP units throughGP LLC .GP LLC is aDelaware limited liability company that also holds the non-economic general partner interest in AAP. AAP is aDelaware limited partnership that, as ofJune 30, 2021 , directly owned a limited partner interest in PAA through its ownership of approximately 245.0 million PAA common units (approximately 31% of PAA's total outstanding common units and Series A preferred units combined). AAP is the sole member ofPAA GP LLC ("PAA GP"), aDelaware limited liability company that directly holds the non-economic general partner interest in PAA. PAA's business model integrates large-scale supply aggregation capabilities with the ownership and operation of critical midstream infrastructure systems that connect major producing regions to key demand centers and export terminals. As one of the largest midstream service providers inNorth America , we own an extensive network of pipeline transportation, terminalling, storage and gathering assets in key crude oil and NGL producing basins (including thePermian Basin ) and transportation corridors and at major market hubs inthe United States andCanada . PAA's assets and the services it provides are primarily focused on crude oil, NGL and natural gas. PAA's business activities are conducted through three operating segments: Transportation, Facilities and Supply and Logistics. See "-Results of Operations-Analysis of Operating Segments" for further discussion. 38

Table of Contents Overview of Operating Results, Capital Investments and Other Significant Activities
During the first six months of 2021, we recognized net income of$181 million as compared to a net loss of$2.556 billion recognized during the first six months of 2020. The net loss for the 2020 period was primarily driven by goodwill impairment losses and non-cash impairment charges 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 totaling approximately$3.24 billion . In addition, we recognized approximately$232 million of inventory valuation adjustments due to declines in commodity prices during the first quarter of 2020. The comparable six month 2021 period includes a net loss on asset sales and asset impairments of$370 million . Results from our reporting segments during the first six months of 2021 decreased from the comparable 2020 period driven primarily by the impact of less favorable crude oil market conditions combined with lower realized NGL margins in our Supply and Logistics segment. In addition, our Facilities segment was unfavorably impacted by reduced NGL capacity utilization and market rates as well as the impact of asset sales. These unfavorable results were partially offset by favorable Transportation segment results that benefited from the collection of deficiency payments associated with minimum volume commitments and lower operating costs.
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
We paid cash distributions of approximately
PAA repurchased 5,290,592 common units for$53 million during the six months endedJune 30, 2021 , including$3 million associated with repurchases executed inDecember 2020 that settled inJanuary 2021 . See "-Liquidity and Capital Resources-Financing Activities-Common Equity Repurchase Program" for additional information. Recent Events InJuly 2021 , we entered into a definitive agreement with Oryx Midstream pursuant to which we and Oryx Midstream intend to merge our respectivePermian Basin assets, operations and commercial activities into a newly formed strategic joint venture,Plains Oryx Permian Basin . The transaction will include all ofOryx's Permian Basin assets and, with the exception of our long-haul pipeline systems and certain of our intra-basin terminal assets, the vast majority of our assets located within thePermian Basin . We will own 65% ofPlains Oryx Permian Basin , operate the combined assets, and consolidate the financial results of the joint venture into our financial statements. Structured as a debt-free joint venture entity through a cashless transaction, this aligns with our financial and portfolio optimization strategies, is near-term free cash flow accretive, and reinforces our ability to maximize free cash flow for our investors, while enhancing our overall credit profile. Subject to satisfaction of customary and other closing conditions and receipt of regulatory approvals, the transactions contemplated by the merger agreement are expected to close in the fourth quarter of 2021. OnAugust 2, 2021 , we completed the sale of ourPine Prairie and Southern Pines natural gas storage facilities for$850 million , subject to certain adjustments. See Note 12 to our Condensed Consolidated Financial Statements for additional information. 39 -------------------------------------------------------------------------------- Table of Contents Results of Operations
The following table sets forth an overview of our consolidated financial results calculated in accordance with GAAP (in millions, except per share data):

** 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 11 to our Condensed Consolidated Financial Statements for additional discussion of such adjustments.
40 -------------------------------------------------------------------------------- Table of Contents 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, including write-downs related to cancelled projects, 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 and 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/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, divestitures, investment capital projects and numerous other factors as discussed, as applicable, in "-Analysis of Operating Segments."

(4)During the periods presented, there were fluctuations in the value of the Canadian dollar ("CAD") to theU.S. dollar ("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. The associated gains and losses are not integral to our results and were thus classified as a selected item impacting comparability. (5)Includes net gains recognized in connection with the repurchase of our outstanding senior notes on the open market. (6)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 (including write-downs related to cancelled projects) 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 11 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. 43 -------------------------------------------------------------------------------- Table of Contents The following tables set forth our operating results from our Transportation segment: Three Months Ended Six Months Ended Operating Results (1) June 30, Variance June 30, Variance (in millions, except per barrel data) 2021 2020 $ % 2021 2020 $ % Revenues$ 553 $ 457 $ 96 21 %$ 1,039 $ 1,036 $ 3 - % Purchases and related costs (60) (44) (16) (36) % (106) (124) 18 15 % Field operating costs (140) (140) - - % (245) (302) 57 19 % Segment general and administrative expenses (2) (28) (24) (4) (17) % (54) (51) (3) (6) % Equity earnings in unconsolidated entities 31 81 (50) (62) % 117 189 (72) (38) % Adjustments: (3) Depreciation and amortization of unconsolidated entities 67 15 52 347 % 87 32 55 172 % Losses from derivative activities and inventory valuation adjustments (1) (6) 5 ** (1) - (1) ** Deficiencies under minimum volume commitments, net 7 4 3 ** (23) - (23) ** Equity-indexed compensation expense 2 3 (1) ** 5 5 - ** Significant transaction-related expenses 2 - 2 ** 2 3 (1) ** Segment Adjusted EBITDA$ 433 $ 346 $ 87 25 %$ 821 $ 788 $ 33 4 % Maintenance capital$ 20 $ 31 $ (11) (35) %$ 47 $ 64 $ (17) (27) % Segment Adjusted EBITDA per barrel$ 0.76 $ 0.64 $ 0.12 19 %$ 0.76 $ 0.66 $ 0.10 15 % Three Months Ended Six Months Ended Average Daily VolumesJune 30 , VarianceJune 30 , Variance (in thousands of barrels per day) (4) 2021 2020 Volumes % 2021 2020 Volumes % Tariff activities volumes Crude oil pipelines (by region):Permian Basin (5) 4,189 4,161 28 1 % 3,972 4,663 (691) (15) %South Texas / Eagle Ford (5) 314 321 (7) (2) % 317 389 (72) (19) % Central (5) 467 355 112 32 % 420 380 40 11 %Gulf Coast 159 118 41 35 % 152 131 21 16 %Rocky Mountain (5) 327 244 83 34 % 307 258 49 19 % Western 256 215 41 19 % 246 209 37 18 %Canada 294 242 52 21 % 305 285 20 7 % Crude oil pipelines 6,006 5,656 350 6 % 5,719 6,315 (596) (9) % NGL pipelines 181 194 (13) (7) % 182 190 (8) (4) % Tariff activities total volumes 6,187 5,850 337 6 % 5,901 6,505 (604) (9) % Trucking volumes 61 64 (3) (5) % 65 80 (15) (19) % Transportation segment total volumes 6,248 5,914 334 6 % 5,966 6,585 (619) (9) %

The following is a discussion of items impacting Transportation segment operating results for the periods indicated.
Revenues, Purchases and Related Costs, Equity Earnings in Unconsolidated Entities and Volumes. The following table presents variances in revenues, purchases and related costs and equity earnings in unconsolidated entities by region:
Favorable/(Unfavorable) Variance Favorable/(Unfavorable) Variance Three Months Ended June 30, Six Months Ended June 30, 2021-2020 2021-2020 Purchases and Equity Purchases and Equity (in millions) Revenues Related Costs Earnings Revenues Related Costs EarningsPermian Basin region$ 60 $ (16)$ (11) $ 7 $ 7$ (17) South Texas / Eagle Ford region (1) - (2) (8) - (12) Central region 8 - (21) 3 1 (24)Gulf Coast region 2 - (12) 2 - (11)Rocky Mountain region 8 - (2) 12 - (8)Canada region 10 - - 5 - - Other regions, NGL pipelines, trucking and pipeline loss allowance revenue 9 - (2) (18) 10 - Total variance$ 96 $ (16)$ (50) $ 3 $ 18$ (72) •Permian Basin region. Revenues, net of purchases and related costs, ("net revenues") increased by$44 million and$14 million for the three and six months endedJune 30, 2021 , respectively, compared to the same periods in 2020 primarily due to the recognition of revenue associated with minimum volume commitments. The recognition of previously deferred revenue associated with minimum volume commitments is reflected as an "Adjustment" in the table above as discussed further below under "-Adjustments: Deficiencies under minimum volume commitments, net." The three-month comparative period was further favorably impacted by higher long-haul movements toCushing, Oklahoma in the second quarter of 2021, as well as an increase in volumes on our gathering pipelines as a result of new connections and increased production, partially offset by lower volumes on our intra-basin pipelines. The six-month comparative period was further unfavorably impacted by lower volumes of crude oil produced in thePermian Basin in the first quarter of 2021, driven by the COVID-19 pandemic-related reset to production and compounded by shut-ins from the extreme winter weather event that occurred in February of 2021 ("Winter Storm Uri"). Equity earnings decreased for the three and six months endedJune 30, 2021 compared to the same periods in 2020 primarily due to our proportionate share of the write-off of costs associated with a capital project canceled during the second quarter of 2021, which is included in the table above as an "Adjustment" in "Depreciation and amortization of unconsolidated entities." The six-month comparative period was further unfavorably impacted by depreciation expense and transition costs associated with phase one of theWink toWebster pipeline being placed into service during the first quarter of 2021, partially offset by lower power costs related to Winter Storm Uri. 45 -------------------------------------------------------------------------------- Table of Contents •South Texas / Eagle Ford region. Revenues decreased for the six months endedJune 30, 2021 compared to the same periods in 2020 due to lower production, including curtailments from Winter Storm Uri. Equity earnings from our 50% interest inEagle Ford Pipeline LLC decreased for the six months endedJune 30, 2021 compared to the same period in 2020 due to a combination of lower joint tariff volumes from thePermian Basin via our Cactus I pipeline, and to a lesser extent, lower regional receipts, partially offset by the recognition of previously deferred revenue associated with minimum volume commitments. The recognition of such revenue is reflected as an "Adjustment" in the table above as discussed further below under "-Adjustments: Deficiencies under minimum volume commitments, net." •Central region. Revenues increased for the three and six months endedJune 30, 2021 compared to the same periods in 2020 primarily due to higher volumes on certain of our pipelines in the region, including theRed River pipeline, as a result of an increase in committed volumes and an expansion placed into service inOctober 2020 . Equity earnings decreased for the three and six months endedJune 30, 2021 compared to the same periods in 2020 primarily due our proportionate share of Diamond Pipeline's write-off of costs associated with the cancellation of the Byhalia Connection construction project during the second quarter of 2021, which is included in the table above as an "Adjustment" in "Depreciation and amortization of unconsolidated entities." •Gulf Coast region. Equity earnings decreased for the three and six months endedJune 30, 2021 compared to the same periods in 2020 primarily due to our proportionate share of Capline Pipeline's write-off of costs associated with the cancellation of the Byhalia Connection construction project during the second quarter of 2021, which is included in the table above as an "Adjustment" in "Depreciation and amortization of unconsolidated entities."
•Rocky Mountain region. Revenues increased for the three and six months ended
Equity earnings decreased for the three and six months ended
•Canada region. Revenues increased for the three and six months endedJune 30, 2021 compared to the same periods in 2020 primarily due to higher volumes from increased production and favorable foreign exchange impacts. Such favorable impacts were partially offset by a decrease in intersegment fees to reflect lower utilization and market rates, which had an offsetting favorable impact on our Supply and Logistics segment. •Other regions, NGL pipelines, trucking and pipeline loss allowance revenue. The increase in net revenues for the three months endedJune 30, 2021 compared to the same period in 2020 was primarily due to higher pipeline loss allowance revenue in 2021 primarily due to higher prices. The decrease in net revenues for the six months endedJune 30, 2021 compared to the same period in 2020 was primarily due to lower pipeline loss allowance revenue due to lower volumes, partially offset by higher prices. Such unfavorable impacts were offset by lower trucking costs driven by lower volumes. 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 months endedJune 30, 2021 and 2020, amounts billed to counterparties exceeded revenue recognized during the periods that was previously deferred. For the six months endedJune 30, 2021 , the recognition of previously deferred revenue exceeded amounts billed to counterparties associated with deficiencies under minimum volume commitments. 46 -------------------------------------------------------------------------------- Table of Contents Field Operating Costs. The decrease in field operating costs for the six months endedJune 30, 2021 compared to the same period in 2020 was primarily due to (i) lower power costs, including the impact of gains related to hedged power costs resulting from Winter Storm Uri and (ii) streamlining efforts which have resulted in decreases in variable costs and maintenance and chemicals and additives costs. Segment General and Administrative Expenses. The increase in segment general and administrative expenses for the three and six months endedJune 30, 2021 compared to the same periods in 2020 was primarily due to increased information systems costs and reduced wage subsidies received by our Canadian subsidiary in the current periods.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 six months endedJune 30, 2021 compared to the same periods in 2020 was primarily due to timing changes, the completion of multi-year reliability improvement programs and application of updated regulatory guidance, among other factors. 47 -------------------------------------------------------------------------------- Table of Contents 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 is a discussion of items impacting Facilities segment operating results.
Revenues, Purchases and Related Costs and Volumes. Variances in net revenues and average monthly volumes were primarily driven by the following:
•NGL Operations. Revenues from our NGL operations decreased by$16 million and$57 million for the three and six months endedJune 30, 2021 , respectively, compared to the same periods in 2020 primarily due to lower intersegment facility fee revenues due to rate decreases at certain of our storage, fractionation and processing facilities to reflect lower utilization and market rates (which had an offsetting favorable impact on our Supply and Logistics segment). The six-month comparative period was further unfavorably impacted by (i) a benefit in the 2020 comparative period from the receipt of a deficiency payment of approximately$20 million upon the expiration of a multi-year contract and (ii) the sale of certain NGL terminals in the second quarter of 2020. Such unfavorable impacts were partially offset for the three- and six-month comparative periods by more favorable foreign exchange impacts in 2021 of approximately$13 million and$19 million , respectively, and, for the six-month comparative period, gains at certain of our fractionation facilities in the first quarter of 2021. •Crude Oil Storage. Revenues from our crude oil storage operations decreased by$16 million and$31 million for the three and six months endedJune 30, 2021 , respectively, compared to the same periods in 2020 primarily due to the sale of ourLos Angeles Basin terminals in October of 2020. •Natural Gas Storage. Net revenues increased by$17 million for the six months endedJune 30, 2021 compared to the same period in 2020 primarily due to increased margins from hub activities in the first quarter of 2021 related to Winter Storm Uri. Field Operating Costs. The decrease in field operating costs for the six months endedJune 30, 2021 compared to the same period in 2020 was primarily due to (i) the sale of ourLos Angeles Basin terminals and certain NGL terminals, (ii) decreased power costs related to derivative activity and (iii) reduced activity at our rail terminals. Segment General and Administrative Expenses. The decrease in segment general and administrative expenses for the three and six months endedJune 30, 2021 compared to the same periods in 2020 was primarily due to the impact of 2020 legal costs, partially offset by reduced wage subsidies received by our Canadian subsidiary in the current period.Maintenance Capital . The decrease in maintenance capital spending for the three and six months endedJune 30, 2021 compared to the same periods in 2020 was primarily due to timing changes, the impact of asset sales, the completion of multi-year reliability improvement programs and application of updated regulatory guidance, among other factors.
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, (iii) the relationship between NGL prices and natural gas prices and (iv) 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. 49

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 and inventory valuation and costing adjustments. 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. Net revenues from our crude oil operations were slightly lower in the three-month period as contango margins were better in the 2020 period; however, this was largely offset by lease gathering margins and certain differentials that were more favorable in the 2021 period. For the six months endedJune 30, 2021 compared to the same period in 2020, net revenues from our crude oil operations were lower due to less favorable market conditions. •NGL Operations. Net revenues from our NGL operations were slightly higher for the three months endedJune 30, 2021 compared to the same period in 2020 due to a decrease in intersegment fees. Net revenues from our NGL operations decreased for the six months endedJune 30, 2021 compared to the same period in 2020, primarily due to lower realized margins on our NGL sales activities, partially offset by a decrease in intersegment fees. The intersegment fees were reduced in the 2021 periods to reflect lower utilization and market rates, and had an offsetting unfavorable impact on our Facilities and Transportation segments. •Impact from Certain Derivative Activities and 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), gains and losses on derivatives that are related to investing activities (such as the purchase of linefill) and inventory valuation adjustments, as applicable. See Note 8 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. •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. 51 -------------------------------------------------------------------------------- Table of Contents •Foreign Exchange Impacts. Our net revenues are impacted by 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 within our Canadian operations. 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 six months endedJune 30, 2021 compared to the same period in 2020 was primarily due to lower trucking costs due to more supply connected to pipelines resulting in lower trucking activity in the 2021 period.
Other Income and Expenses
Depreciation and Amortization
The increase in depreciation and amortization expense for the three and six
months ended
Gains/(Losses) on Asset Sales and Asset Impairments, Net
The net loss on asset sales and asset impairments for the three and six months endedJune 30, 2021 , was primarily driven by an approximate$475 million non-cash impairment charge related to the write-down of ourPine Prairie and Southern Pines natural gas storage facilities upon classification as held for sale during the second quarter, which were subsequently sold onAugust 2, 2021 , partially offset by a gain of$106 million related to the Asset Exchange transaction. See Note 12 to our Condensed Consolidated Financial Statements for additional information. The net loss on asset sales and asset impairments for the six months endedJune 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 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 during the quarter, which were subsequently sold. Goodwill Impairment Losses
During the first quarter of 2020, we recognized a goodwill impairment charge of
Gain on/(Impairment of) Investments in Unconsolidated Entities, Net
During the three and six months endedJune 30, 2020 , we recognized losses of$69 million and$112 million , respectively, related to the write-down of certain of our investments in unconsolidated entities. Additionally, during the six months endedJune 30, 2020 , we recognized a gain of$21 million related to our sale of a 10% interest inSaddlehorn Pipeline Company, LLC .

(2)The activity during the periods presented was primarily related to the impact from the change inthe 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 income tax expense for the six months endedJune 30, 2021 compared to the income tax benefit for the six months endedJune 30, 2020 was primarily due to the impact of higher earnings at PAA on income attributable to PAGP in the first quarter of 2021 compared to the first quarter of 2020, which was partially offset by the impact of lower earnings at PAA on income attributable to PAGP for the second quarter of 2021 compared to the second quarter of 2020.
Liquidity and Capital Resources
General
On a consolidated basis, our primary sources of liquidity are (i) cash flow from operating activities and (ii) borrowings under PAA's credit facilities or the PAA commercial paper program. In addition, we may supplement these primary sources of liquidity with proceeds from our divestiture program and in the past we have utilized funds received from sales of equity and debt securities. 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. In addition, we may use cash for repurchases of common equity. 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 ofJune 30, 2021 , although we had a working capital deficit of$485 million , we had approximately$2.6 billion of liquidity available to meet our ongoing operating, investing and financing needs, subject to continued covenant compliance, as noted below (in millions): As of June 30, 2021 Availability under PAA senior unsecured revolving credit facility (1) (2)$ 1,532 Availability under PAA senior secured hedged inventory facility (1) (2) 1,387 Amounts outstanding under PAA commercial paper program (388) Subtotal 2,531 Cash and cash equivalents 26 Total$ 2,557 (1)Represents availability prior to giving effect to borrowings outstanding under the PAA commercial paper program, which reduce available capacity under the facilities. (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$68 million and$13 million , respectively. Usage of PAA's credit facilities, and, in turn, its commercial paper program, is subject to ongoing compliance with covenants. The credit agreements for PAA's revolving credit facilities (which impact PAA's ability to access its commercial paper program because they provide the financial backstop that supports its short-term credit ratings) and its 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. Additionally, lack of compliance with the provisions in PAA's credit agreements may restrict its ability to make distributions of available cash. PAA was in compliance with the covenants contained in its credit agreements and indentures as ofJune 30, 2021 . 53 -------------------------------------------------------------------------------- Table of Contents 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 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, including extended disruptions in the financial markets and/or energy price volatility resulting from current macroeconomic and geopolitical conditions associated with the COVID-19 pandemic and/or actions byOrganization of Petroleum Exporting Countries ("OPEC"). A prolonged material decrease in our cash flows would likely produce an adverse effect on our borrowing capacity and cost of borrowing. Our borrowing capacity and borrowing costs are also impacted by PAA's credit rating. See Item 1A. "Risk Factors" included in our 2020 Annual Report on Form 10-K for further discussion regarding 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 2020 Annual Report on Form 10-K.
Net cash provided by operating activities for the first six months of 2021 and 2020 was$1.023 billion and$972 million , respectively, and primarily resulted from earnings from our operations. Additionally, during the six months endedJune 30, 2020 , we increased the volume of our crude oil inventory to be stored during the contango market; however, this increase was offset by lower prices for our inventory stored at the end of the current period compared to the end of 2019. Investing Activities Capital Expenditures In addition to our operating needs, we also use cash for our investment capital projects, maintenance capital activities and acquisition activities. We fund these expenditures with cash generated by operating activities, financing activities and/or proceeds from our divestiture program. In the near term, we do not plan to issue common equity to fund such expenditures. The following table summarizes our investment, maintenance and acquisition capital expenditures (in millions): Six Months Ended June 30, 2021 2020 Investment capital (1) (2)$ 142 $ 654 Maintenance capital (1) 73 104 Acquisition capital (3) 32 308$ 247 $ 1,066 (1)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." (2)Includes contributions to unconsolidated entities, accounted for under the equity method of accounting, related to investment capital projects by such entities. (3)Acquisition capital for 2021 represents the cash consideration paid as part of the Asset Exchange transaction. See Note 12 to our Condensed Consolidated Financial Statements for additional information. Acquisition capital for 2020 primarily includesFelix Midstream LLC , a crude oil gathering system located in theDelaware Basin . 54 -------------------------------------------------------------------------------- Table of Contents 2021 Investment andMaintenance Capital . Total projected investment capital for the year endedDecember 31, 2021 is$325 million , a majority of which will be invested in our fee-based Transportation and Facilities segments. Additionally, maintenance capital for the full year of 2021 is projected to be$180 million . We expect to fund our 2021 investment and maintenance capital expenditures with retained cash flow and proceeds from assets sold as part of our divestiture program.
Divestitures
We continue to evaluate potential sales of non-core assets and/or sales of partial interests in assets to strategic joint venture partners. The following table summarizes the proceeds received during the first six months of 2021 and 2020 from sales of assets, which were previously reported in our Transportation and Facilities segments (in millions): Six Months Ended June 30, 2021 2020 Proceeds from divestitures$ 22 $ 245
Proceeds from divestitures were used to reduce debt levels and fund our investment capital projects.
OnAugust 2, 2021 , we closed the sale of ourPine Prairie and Southern Pines natural gas storage facilities for$850 million , subject to certain adjustments. See Note 12 to our Condensed Consolidated Financial Statements for additional information.
Ongoing Activities Related to Strategic Transactions
We are continuously engaged in the evaluation of potential transactions that support our current business strategy. While in the past such transactions have included acquisitions and large capital projects, consistent with our current strategic focus on capital discipline, leverage reduction, portfolio optimization and free cash flow generation, we are currently primarily focused on evaluating whether we should (i) sell assets that we regard as non-core or that we believe might be a better fit with the business and/or assets of a third-party buyer or (ii) sell partial interests in assets to strategic joint venture partners, in each case to optimize our asset portfolio and strengthen our balance sheet and leverage metrics. With respect to a potential divestiture, we may also conduct an auction process or may negotiate a transaction with one or a limited number of potential buyers. Such transactions could involve assets that, if sold or put into a joint venture or joint ownership arrangement, could have a material effect on our financial condition and results of operations. 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 efforts with respect to any such transactions will be successful, and we can provide no assurance that our financial expectations with respect to such transactions will ultimately be realized. See Item 1A. "Risk Factors-Risks Related to PAA's Business-Divestitures, joint ventures, joint ownership arrangements and acquisitions involve risks that may adversely affect our business" included in our 2020 Annual Report on Form 10-K.
Financing Activities
Our financing activities primarily relate to funding investment capital projects, acquisitions and refinancing of our 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.
55 -------------------------------------------------------------------------------- Table of Contents Borrowings and Repayments Under Credit Arrangements During the six months endedJune 30, 2021 , we had net repayments on the PAA credit facilities and commercial paper program of$326 million . The net repayments resulted primarily from cash flow from operating activities and proceeds from asset sales, which offset borrowings during the period related to funding needs for capital investments, inventory purchases and other general partnership purposes. During the six months endedJune 30, 2020 , we had net repayments on the PAA credit facilities and commercial paper program of$418 million . The net repayments resulted primarily from cash flow from operating activities, proceeds from asset sales and the issuance of$750 million , 3.80% senior notes inJune 2020 , which offset borrowings during the period related to funding needs for capital investments, inventory purchases and other general partnership purposes. In connection with the sale of ourPine Prairie and Southern Pines natural gas storage facilities onAugust 2, 2021 , we repaid PAA's twoGO Zone term loans totaling$200 million . See Note 12 for additional information regarding the sale of our natural gas storage facilities.
Common Equity Repurchase Program
PAA repurchased 5,290,592 common units under the Program through open market purchases that settled during the six months endedJune 30, 2021 . The total purchase price of these repurchases was$53 million , including commissions and fees. AtJune 30, 2021 , the remaining available capacity under the Program was$397 million . Registration Statements PAGP Registration Statements. We have filed with theSEC a shelf registration statement that, subject to effectiveness at the time of use, allows us to issue, in the aggregate, up to a specified amount of equity securities (the "PAGP Traditional Shelf"), under which we had approximately$939 million of unsold securities available atJune 30, 2021 . 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 six months endedJune 30, 2021 . PAA Registration Statements. PAA periodically accesses the capital markets for both equity and debt financing. PAA has filed with theSEC a universal shelf registration statement that, subject to effectiveness at the time of use, allows PAA to issue, in the aggregate, up to a specified amount of debt or equity securities (the "PAA Traditional Shelf"), under which PAA had approximately$1.1 billion of unsold securities available atJune 30, 2021 . 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. PAA did not conduct any offerings under the PAA Traditional Shelf or the PAA WKSI Shelf during the six months endedJune 30, 2021 .
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 legal or contractual obligations and funding of future distributions to our shareholders. See Item 5. "Market for Registrant's Shares, Related Shareholder Matters and Issuer Purchases of Equity Securities-Cash Distribution Policy" included in our 2020 Annual Report on Form 10-K for additional discussion regarding distributions.
See Note 7 to our Condensed Consolidated Financial Statements for details of distributions paid during or pertaining to the first six months of 2021.
56 -------------------------------------------------------------------------------- Table of Contents Distributions to Noncontrolling Interests Distributions to noncontrolling interests represent amounts paid on interests in consolidated entities that are not owned by us. As ofJune 30, 2021 , 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 21% limited partner interest in AAP and (iii) a 33% interest inRed River LLC . See Note 7 to our Condensed Consolidated Financial Statements for details of distributions to noncontrolling interests paid during or pertaining to the first six months of 2021.
Contingencies
For a discussion of contingencies that may impact us, see Note 10 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
Remainder of 2026 and 2021 2022 2023 2024 2025 Thereafter Total Long-term debt and related interest payments (1)$ 402 $ 1,137 $ 1,461 $ 1,083 $ 1,300 $ 8,337 $ 13,720 Leases (2) 54 102 78 64 49 299 646 Other obligations (3) 197 408 329 282 269 935 2,420 Subtotal 653 1,647 1,868 1,429 1,618 9,571 16,786 Crude oil, NGL and other purchases (4) 11,039 19,545 18,494 17,483 14,182 54,615 135,358 Total$ 11,692 $ 21,192 $ 20,362 $ 18,912 $ 15,800 $ 64,186 $ 152,144 (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 6 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) land, (iii) office space, (iv) storage tanks, (v) tractor trailers and (vi) vehicles. See Note 14 to our Consolidated Financial Statements included in Part IV of our 2020 Annual Report on Form 10-K for additional information. 57 -------------------------------------------------------------------------------- Table of Contents (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$1.9 billion associated with agreements to store crude oil at facilities and transport crude oil or utilize capacity on pipelines owned by equity method investees at posted tariff rates or prices that we believe approximate market. 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 duringJune 2021 . 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. AtJune 30, 2021 andDecember 31, 2020 , we had outstanding letters of credit of approximately$81 million and$129 million , respectively.
Off-Balance Sheet Arrangements
We have no off-balance sheet arrangements as defined by Item 303 of Regulation S-K.

Critical Accounting Policies and Estimates
For a discussion regarding our critical accounting policies and estimates, see "Critical Accounting Policies and Estimates" under Item 7 of our 2020 Annual Report on Form 10-K.
Change in Accounting Estimate
In early 2021, we conducted a review to assess the useful lives of our property and equipment. Based on this review, we modified the useful lives of certain of our Pipelines and related facilities and Storage, terminal and rail facilities to useful lives of 10 to 50 years from useful lives of 10 to 70 years to reflect current expectations given our future operating and commercial outlook. This change in accounting estimate was effectiveJanuary 1, 2021 . Based on the net carrying amount of this property and equipment as ofJanuary 1, 2021 , we currently estimate that these useful life reductions will prospectively increase annual depreciation expense by approximately$72 million .
