Notes to Consolidated Financial StatementsPhillips 66 Partners LP
 
Note 1—Description of the Business
Unless otherwise stated or the context otherwise indicates, all references to “Phillips 66 Partners,” “the Partnership,” “us,” “our,” “we,” or similar expressions refer to Phillips 66 Partners LP, including its consolidated subsidiaries. References to Phillips 66 may refer to Phillips 66 and/or its subsidiaries, depending on the context. References to our “General Partner” or “GP” refer to Phillips 66 Partners GP LLC, and references to “Phillips 66 PDI” refer to Phillips 66 Project Development Inc., the Phillips 66 subsidiary that holds a limited partner interest in us and wholly owns our General Partner.

We are a growth-oriented master limited partnership formed to own, operate, develop and acquire primarily fee-based midstream assets. Our operations consist of crude oil, refined petroleum products and natural gas liquids (NGL) transportation, terminaling, processing and storage assets. We conduct our operations through both wholly owned and joint venture operations. The majority of our wholly owned assets are associated with, and are integral to the operation of, nine of Phillips 66’s owned or joint venture refineries. Our operations consist of one reportable segment.

We primarily generate revenue by providing fee-based transportation, terminaling, processing, storage and fractionation services to Phillips 66 and other customers. Our equity affiliates primarily generate revenue from transporting and terminaling crude oil, refined petroleum products and NGL. Since we do not own any of the crude oil, refined petroleum products and NGL we handle and do not engage in the trading of those commodities, we have limited direct exposure to risks associated with fluctuating commodity prices, although these risks indirectly influence our activities and results of operations over the long term.


Note 2—Interim Financial Information

The unaudited interim financial information presented in the financial statements included in this report is prepared in accordance with generally accepted accounting principles in the United States (GAAP) and includes all known accruals and adjustments necessary, in the opinion of management, for a fair presentation of our financial position, results of operations and cash flows for the periods presented. Unless otherwise specified, all such adjustments are of a normal and recurring nature. Certain notes and other information have been condensed or omitted from the interim financial statements included in this report. Therefore, these interim financial statements should be read in conjunction with the audited consolidated financial statements and notes included in our 2020 Annual Report on Form 10-K. The results of operations for the three months ended March 31, 2021, are not necessarily indicative of the results to be expected for the full year.

The COVID-19 pandemic continues to disrupt economic activities globally. Reduced demand for petroleum products has resulted in decreased volumes through logistics infrastructure. The depth and duration of the economic consequences of the COVID-19 pandemic remain uncertain. We continuously monitor our asset and investment portfolio for impairments in this challenging business environment. We recorded an impairment totaling $198 million in the first quarter of 2021, and additional impairments may be required in the future. See Note 4—Equity Investments for additional information.


Note 3—Operating Revenues

Operating revenues are primarily generated from long-term pipeline transportation, terminaling, storage, processing and fractionation lease and service agreements, mainly with Phillips 66. These agreements typically include escalation clauses to adjust transportation tariffs and terminaling and storage fees to reflect changes in price indices. In addition, most of these agreements contain renewal options, which typically require the mutual consent of both our customers and us.

The majority of our agreements with Phillips 66 are considered operating leases under GAAP. The classification of a lease as either an operating or a financing lease requires judgment in assessing the contract’s lease and service components and in determining the asset’s fair value. We have elected to account for lease and service elements of contracts classified as leases on a combined basis, except for leases of processing-type assets, which contain non-ratable fees related to turnaround activity. For these types of leases, we continue to separate the lease and service elements based on relative standalone prices and apply the lease standard to the lease element and the revenue standard to the service element.

Deferred Revenues
Our deferred revenues represent payments received from our customers, mainly Phillips 66, in advance of the period in which lease and service contract performance obligations have been fulfilled. The majority of our deferred revenues relate to a tolling agreement and a storage agreement that are classified as leases. The remainder of our deferred revenues relate to lease and service agreements that contain minimum volume commitments with recovery provisions. Our deferred revenues are recorded in the “Deferred revenues” and “Other liabilities” line items on our consolidated balance sheet.

Remaining Performance Obligations
We typically have long-term service contracts with our customers, mainly Phillips 66, of which the original durations range from 5 to 15 years. The weighted-average remaining duration of these contracts is 9 years. These contracts include both fixed and variable transaction price components. At March 31, 2021, future service revenues expected to be recognized for the fixed component of the transaction price of our remaining performance obligations from service contracts with our customers that have an original expected duration of greater than one year were:

Dakota Access, LLC (Dakota Access) and Energy Transfer Crude Oil Company, LLC (ETCO)
In March 2019, a wholly owned subsidiary of Dakota Access issued $2.5 billion aggregate principal amount of senior unsecured notes. Dakota Access and ETCO have guaranteed repayment of the notes.  In addition, we and our co-venturers in Dakota Access provided a Contingent Equity Contribution Undertaking (CECU) in conjunction with the notes offering.  Under the CECU, the co-venturers may be severally required to make proportionate equity contributions to Dakota Access if there is an unfavorable final judgment in the ongoing litigation related to an easement granted by the U.S. Army Corps of Engineers (USACE) to allow the pipeline to be constructed under Lake Oahe in North Dakota. Contributions may be required if Dakota Access determines that the issues included in any such final judgment cannot be remediated and Dakota Access has or is projected to have insufficient funds to satisfy repayment of the notes. If Dakota Access undertakes remediation to cure issues raised in a final judgment, contributions may be required if any series of the notes become due, whether by acceleration or at maturity, during such time, to the extent Dakota Access has or is projected to have insufficient funds to pay such amounts. At March 31, 2021, our share of the maximum potential equity contributions under the CECU was approximately $631 million.

In July 2020, the trial court presiding over the litigation vacated Dakota Access’ easement under Lake Oahe and ordered the Dakota Access Pipeline to be shut down and emptied of crude oil pending the preparation of an Environmental Impact Statement (EIS) by the USACE, which had been ordered by the court in March 2020 and is now expected to be completed by March 2022. In August 2020, pending an appeal of the trial court’s decisions, an appellate court denied Dakota Access’ motion to stay the order vacating the easement, but granted its motion to stay the order that the pipeline be shut down while the EIS is prepared. In January 2021, the appellate court affirmed the trial court’s order vacating the easement and directing the USACE to prepare an EIS and reversed the order directing the pipeline to be shut down. Notwithstanding that the easement has been vacated, in April 2021, the USACE indicated that it currently intends to allow the pipeline to continue to operate while it proceeds with the EIS. Currently, there is a motion for a permanent injunction to shut down the pipeline before the trial court that could be decided at any time. Additionally, Dakota Access has requested the appellate court to stay its January 2021 decision pending a filing and disposition of a petition for writ of certiorari to the U.S. Supreme Court.

If the pipeline is required to cease operations, either permanently or pending the preparation of the EIS, and should Dakota Access and ETCO not have sufficient funds to pay ongoing expenses, we also could be required to support our share of the ongoing expenses, including scheduled interest payments on the notes of approximately $25 million annually, in addition to the potential obligations under the CECU.

Gray Oak Pipeline, LLC
Gray Oak Pipeline, LLC was formed to develop and construct the Gray Oak Pipeline, which transports crude oil from the Permian and Eagle Ford to Texas Gulf Coast destinations that include Corpus Christi and the Sweeny area, including the Phillips 66 Sweeny Refinery, as well as access to the Houston market. We have a consolidated holding company that owns 65% of Gray Oak Pipeline, LLC. In December 2018, a third party exercised its option to acquire a 35% interest in the holding company. Because the holding company’s sole asset was its ownership interest in Gray Oak Pipeline, LLC, which was considered a financial asset, and because certain restrictions were placed on the third party’s ability to transfer or sell its interest in the holding company during the construction of the Gray Oak Pipeline, the legal sale of the 35% interest did not qualify as a sale under GAAP at that time. The Gray Oak Pipeline commenced full operations in the second quarter of 2020 and the restrictions placed on the co-venturer were lifted on June 30, 2020, resulting in the recognition of the sale under GAAP. Accordingly, at June 30, 2020, the co-venturer’s 35% interest in the holding company was recharacterized from a long-term obligation to a noncontrolling interest on our consolidated balance sheet. We have an effective ownership interest of 42.25% in Gray Oak Pipeline, LLC, after considering our co-venturer’s 35% interest in the consolidated holding company.

Liberty
At March 31, 2021, we held a 50% interest in Liberty, a joint venture formed to develop and construct the Liberty Pipeline system. Liberty was considered a VIE because it did not have sufficient equity at risk to fully fund the construction of all assets required for principal operations. We determined we were not the primary beneficiary because we and our co-venturer jointly directed the activities of Liberty that most significantly impact economic performance.

In the first quarter of 2021, we decided to exit the Liberty Pipeline project, which had previously been deferred due to the challenging business environment created by the COVID-19 pandemic. As a result, we recorded a $198 million impairment to reduce the book value of our investment in Liberty at March 31, 2021, to our share of the estimated fair value of the joint venture’s pipeline assets and net working capital. The impairment is included in the “Impairments” line item on our consolidated statement of income (loss). This valuation resulted in a Level 3 nonrecurring fair value measurement. At March 31, 2021, the book value of our investment in Liberty, and our maximum exposure to loss, was $46 million.

In April 2021, we transferred our ownership interest in Liberty to our co-venturer for cash and certain pipeline assets with an estimated fair value that approximated our book value at March 31, 2021.

Note 5—Net Income (Loss) Per Limited Partner Unit

We calculate net income (loss) attributable to the Partnership per limited partner unit by dividing the limited partners’ interest in net income (loss) by the weighted-average number of common units outstanding for the period. After considering the period’s cash distributions declared, the remaining undistributed earnings or excess distributions declared over earnings, if any, are allocated to participating securities in accordance with the contractual terms of our partnership agreement and as prescribed under the two-class method for those periods in which we have participating securities. Our preferred units became participating securities effective October 1, 2020. See Note 9—Equity for additional information on our preferred units.

For the diluted net income (loss) per limited partner unit calculation, the preferred units are assumed to be converted at the beginning of the period into common limited partner units on a one-for-one basis, and the distribution formula for available cash in our partnership agreement is recalculated, using the original available cash amount increased only for the preferred distributions declared which would not have been paid after conversion. Any potentially dilutive securities are excluded from the diluted earnings per unit computation if the effect of including such securities would be anti-dilutive.

On April 20, 2021, the Board of Directors of our General Partner declared a quarterly cash distribution of $0.875 per common unit, which will result in a total distribution of $200 million attributable to the first quarter of 2021. This distribution is payable on May 14, 2021, to common unitholders of record as of April 30, 2021.

Beginning with the distribution to preferred unitholders attributable to the fourth quarter of 2020, the preferred unitholders are entitled to receive cumulative quarterly distributions equal to the greater of $0.678375 per unit, or the per-unit distribution amount paid to the common unitholders. Preferred unitholders will receive $12 million of distributions attributable to the first quarter of 2021. This distribution is payable May 14, 2021, to preferred unitholders of record as of April 30, 2021.

Table of Contents
At March 31, 2021, and December 31, 2020, borrowings of $450 million and $415 million were outstanding under our $750 million revolving credit facility, respectively. At both March 31, 2021, and December 31, 2020, $1 million in letters of credit had been issued that were supported by this facility.

Debt Repayment
On April 1, 2021, we repaid the two remaining $25 million tranches of tax-exempt bonds due April 2021, totaling $50 million.

Debt Issuance
On April 6, 2021, we entered into a $450 million term loan agreement and borrowed the full amount. The term loan agreement has a maturity date of April 5, 2022, and the outstanding borrowings can be repaid at any time and from time to time, in whole or in part, without premium or penalty. Borrowings bear interest at a floating rate based on either a Eurodollar rate or a reference rate, plus a margin of 0.875%. Proceeds were primarily used to repay amounts borrowed under our $750 million revolving credit facility.


Note 8—Contingencies

From time to time, lawsuits involving a variety of claims that arise in the ordinary course of business are filed against us. We also may be required to remove or mitigate the effects on the environment of the placement, storage, disposal or release of certain chemical, mineral and petroleum substances at various sites. We regularly assess the need for accounting recognition or disclosure of these contingencies. In the case of all known contingencies (other than those related to income taxes), we accrue a liability when the loss is probable and the amount is reasonably estimable. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not reduce these liabilities for potential insurance or third-party recoveries. If applicable, we accrue receivables for probable insurance or other third-party recoveries. In the case of income-tax-related contingencies, we use a cumulative probability-weighted loss accrual in cases where sustaining a tax position is uncertain.

Based on currently available information, we believe it is remote that future costs related to known contingent liability exposures will exceed current accruals by an amount that would have a material adverse impact on our consolidated financial statements. As we learn new facts concerning contingencies, we reassess our position both with respect to accrued liabilities and other potential exposures. Estimates particularly sensitive to future changes include any contingent liabilities recorded for environmental remediation, tax and legal matters. Estimated future environmental remediation costs are subject to change due to such factors as the uncertain magnitude of cleanup costs, the unknown time and extent of such remedial actions that may be required, and the determination of our liability in proportion to that of other potentially responsible parties. Estimated future costs related to tax and legal matters are subject to change as events evolve and as additional information becomes available during the administrative and litigation processes.

Environmental
We are subject to federal, state and local environmental laws and regulations. We record accruals for contingent environmental liabilities based on management’s best estimates, using all information that is available at the time. We measure estimates and base liabilities on currently available facts, existing technology, and presently enacted laws and regulations, taking into account stakeholder and business considerations. When measuring environmental liabilities, we also consider our prior experience in remediation of contaminated sites, other companies’ cleanup experience, and data released by the U.S. Environmental Protection Agency or other organizations. We consider unasserted claims in our determination of environmental liabilities, and we accrue them in the period they are both probable and reasonably estimable. At March 31, 2021, and December 31, 2020, our total environmental accruals were not material.

In the future, we may be involved in additional environmental assessments, cleanups and proceedings.

Legal Proceedings
Under our amended omnibus agreement, Phillips 66 provides certain services for our benefit, including legal support services, and we pay an operational and administrative support fee for these services. Phillips 66’s legal organization applies its knowledge, experience and professional judgment to the specific characteristics of our cases, employing a litigation management process to manage and monitor the legal proceedings against us. The process facilitates the early evaluation and quantification of potential exposures in individual cases and enables tracking of those cases that have been scheduled for trial and/or mediation. Based on professional judgment and experience in using these litigation management tools and available information about current developments in all our cases, Phillips 66’s legal organization regularly assesses the adequacy of current accruals and determines if adjustment of existing accruals, or establishment of new accruals, is required. As of March 31, 2021, and December 31, 2020, we did not have any material accrued contingent liabilities associated with litigation matters.

Indemnification and Excluded Liabilities
Under our amended omnibus agreement and pursuant to the terms of various agreements under which we acquired assets from Phillips 66, Phillips 66 will indemnify us, or assume responsibility, for certain environmental liabilities, tax liabilities, litigation and any other liabilities attributable to the ownership or operation of the assets contributed to us and that arose prior to the effective date of each acquisition. These indemnifications and exclusions from liability have, in some cases, time limits and deductibles. When Phillips 66 performs under any of these indemnifications or exclusions from liability, we recognize noncash expenses and associated noncash capital contributions from our General Partner, as these are considered liabilities paid for by a principal unitholder.


Note 9—Equity

ATM Programs
We have authorized an aggregate of $750 million under three $250 million continuous offerings of common units, or at-the-market (ATM) programs. The first two programs concluded in June 2018 and December 2019, respectively. We suspended issuances under the ATM program in the first quarter of 2020 due to low common unit prices. We did not issue any common units under the current ATM program during the three months ended March 31, 2021.

Preferred Units
Beginning with the distribution to preferred unitholders attributable to the fourth quarter of 2020, the preferred unitholders are entitled to receive cumulative quarterly distributions equal to the greater of $0.678375 per unit, or the per-unit distribution amount paid to the common unitholders as if such preferred units had converted into common units immediately prior to the record date. The holders of the preferred units may convert their preferred units into common units, on a one-for-one basis, at any time, in full or in part, subject to minimum conversion amounts and conditions.


Note 10—Related Party Transactions

Commercial Agreements
We have entered into long-term, fee-based commercial agreements with Phillips 66 to provide transportation, terminaling, storage, stevedoring, fractionation, processing, and rail terminal services. Under these agreements, Phillips 66 commits to provide us with minimum transportation, throughput or storage volumes, or minimum monthly service fees. If Phillips 66 does not meet its minimum volume commitments under an agreement, Phillips 66 pays us a deficiency payment based on the calculation described in the agreement.

Amended and Restated Operational Services Agreement
Under our amended and restated operational services agreement, we reimburse Phillips 66 for certain operational services provided in support of our pipelines, terminaling, processing, and storage facilities. These services include routine and emergency maintenance and repair services, routine operational activities, routine administrative services, construction and related services and such other services as we and Phillips 66 may mutually agree upon from time to time.

Table of Contents
Amended Omnibus Agreement
The amended omnibus agreement addresses our payment of an operating and administrative support fee and our obligation to reimburse Phillips 66 for all other direct or allocated costs and expenses incurred by Phillips 66 in providing general and administrative services. Additionally, the omnibus agreement addresses Phillips 66’s indemnification to us and our indemnification to Phillips 66 for certain environmental and other liabilities. Further, it addresses the granting of a license from Phillips 66 to us with respect to the use of certain Phillips 66 trademarks.

The operational and administrative support fee is for the provision of certain services, including: logistical services; asset oversight, such as operational management and supervision; corporate engineering services, including asset integrity and regulatory services; business development services; executive services; financial and administrative services (including treasury and accounting); information technology; legal services; corporate health, safety and environmental services; facility services; human resources services; procurement services; investor relations; tax matters; and public company reporting services. We pay Phillips 66 an operational and administrative support fee under the terms of our amended omnibus agreement in the amount of $8 million per month.

We also reimburse Phillips 66 for all other direct or allocated costs incurred on behalf of us, pursuant to the terms of our amended omnibus agreement. The classification of these charges between operating and maintenance expenses and general and administrative expenses is based on the functional nature of the services performed for our operations. Under our amended and restated operational services agreement, we reimburse Phillips 66 for the provision of certain operational services in support of our operating assets. Additionally, we pay Phillips 66 for insurance services provided to us, and recoveries under these policies are recorded as an offset to our expenses. Operating and maintenance expenses also include volumetric gains and losses associated with volumes transported by Phillips 66.

Tax Sharing Agreement
Under our tax sharing agreement, we reimburse Phillips 66 for our share of state and local income and other taxes incurred by Phillips 66 due to our results of operations being included in a combined or consolidated tax return filed by Phillips 66. Any reimbursement is limited to the tax that we (and our subsidiaries) would have paid had we not been included in a combined group with Phillips 66. Phillips 66 may use its tax attributes to cause its combined or consolidated group to owe no tax; however, we would nevertheless reimburse Phillips 66 for the tax we would have owed, even though Phillips 66 had no cash expense for that period.

EXECUTIVE OVERVIEW AND BUSINESS ENVIRONMENT

Partnership Overview
We are a growth-oriented master limited partnership formed to own, operate, develop and acquire primarily fee-based midstream assets. Our operations consist of crude oil, refined petroleum products and natural gas liquids (NGL) transportation, terminaling, processing and storage assets. We conduct our operations through both wholly owned and joint venture operations. The majority of our wholly owned assets are associated with, and are integral to the operation of, nine of Phillips 66’s owned or joint venture refineries.

We primarily generate revenue by providing fee-based transportation, terminaling, processing, storage and fractionation services to Phillips 66 and other customers. Our equity affiliates primarily generate revenue from transporting and terminaling crude oil, refined petroleum products and NGL.

Our common units trade on the New York Stock Exchange under the symbol PSXP.

How We Evaluate Our Operations
Our management uses a variety of financial and operating metrics to analyze our performance, including: (1) volumes handled; (2) operating and maintenance expenses; (3) net income (loss) before net interest expense, income taxes, depreciation and amortization (EBITDA); (4) adjusted EBITDA; and (5) distributable cash flow.

Volumes Handled
The amount of revenue we generate primarily depends on the volumes of crude oil, refined petroleum products and NGL that we handle in our pipeline, terminal, rail rack, processing, storage and fractionator systems. In addition, our equity affiliates generate revenue from transporting and terminaling crude oil, refined petroleum products and NGL. These volumes are primarily affected by the supply of, and demand for, crude oil, refined petroleum products and NGL in the markets served directly or indirectly by our assets, as well as the operational status of the refineries served by our assets. Phillips 66 has committed to minimum throughput volumes under many of our commercial agreements.

19

Table of Contents
Operating and Maintenance Expenses
Our management seeks to maximize the profitability of our operations by effectively managing operating and maintenance expenses. These expenses primarily consist of labor expenses (including contractor services), utility costs, and repair and maintenance expenses. Operating and maintenance expenses generally remain relatively stable across broad ranges of throughput volumes but can fluctuate from period to period depending on the mix of activities, particularly maintenance activities, performed during the period. Our processing assets are periodically subject to major maintenance, or turnaround activities, which can significantly increase operating and maintenance expenses in a given year. Although we seek to manage our maintenance expenditures on our facilities to avoid significant variability in our quarterly cash flows, we balance this approach with our high standards of safety and environmental stewardship, such that critical maintenance is regularly performed.

Our operating and maintenance expenses are also affected by volumetric gains/losses resulting from variances in meter readings and other measurement methods, as well as volume fluctuations due to pressure and temperature changes. Under certain commercial agreements with Phillips 66, the value of any crude oil, refined petroleum product and NGL volumetric gains and losses are determined by reference to the monthly average reference price for the applicable commodity. Any gains/losses under these provisions decrease or increase, respectively, our operating and maintenance expenses in the period in which they are realized. These contractual volumetric gain/loss provisions could increase variability in our operating and maintenance expenses.

EBITDA, Adjusted EBITDA and Distributable Cash Flow
We define EBITDA as net income (loss) plus net interest expense, income taxes, depreciation and amortization.

Adjusted EBITDA is EBITDA attributable to the Partnership after deducting the adjusted EBITDA attributable to noncontrolling interest, further adjusted for:

The proportional share of equity affiliates’ net interest expense, income taxes, depreciation and amortization, and impairments.

Transaction costs associated with acquisitions.

Certain other noncash items, including gains and losses on asset sales and asset impairments.

Distributable cash flow is defined as adjusted EBITDA less (i) equity affiliate distributions less than proportional adjusted EBITDA, (ii) maintenance capital expenditures, (iii) net interest expense, (iv) income taxes paid and (v) preferred unit distributions, plus adjustments for deferred revenue impacts.

EBITDA, adjusted EBITDA, and distributable cash flow are not presentations made in accordance with generally accepted accounting principles in the United States (GAAP). EBITDA, adjusted EBITDA and distributable cash flow are non-GAAP supplemental financial measures that management believes external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may find useful to assess:

Our operating performance as compared to other publicly traded partnerships in the midstream energy industry, without regard to historical cost basis or, in the case of EBITDA and adjusted EBITDA, financing methods.

The ability of our business to generate sufficient cash to support our decision to make distributions to our unitholders.

Our ability to incur and service debt and fund capital expenditures.

The viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

20

Table of Contents
The GAAP performance measure most directly comparable to EBITDA and adjusted EBITDA is net income (loss). The GAAP liquidity measure most directly comparable to EBITDA and distributable cash flow is net cash provided by operating activities. These non-GAAP financial measures should not be considered alternatives to GAAP net income (loss) or net cash provided by operating activities. They have important limitations as analytical tools because they exclude some items that affect net income (loss) and net cash provided by operating activities. Additionally, because EBITDA, adjusted EBITDA, and distributable cash flow may be defined differently by other companies in our industry, our definition of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.


Business Environment
We do not own any of the crude oil, refined petroleum products and NGL we handle and do not engage in the trading of those commodities, and therefore have limited direct exposure to risks associated with fluctuating commodity prices, although these risks indirectly influence our activities and results of operations over the long term.

Our throughput volumes primarily depend on the volume of crude oil processed and refined petroleum products produced at Phillips 66’s owned or operated refineries with which our assets are integrated. These volumes are primarily dependent on Phillips 66’s refining margins and maintenance schedules. Refining margins depend on the price of crude oil or other feedstocks and the price of refined petroleum products. These prices are affected by numerous factors beyond our or Phillips 66’s control, including the domestic and global supply of and demand for crude oil and refined petroleum products. Throughput volumes of our equity affiliates primarily depend on upstream drilling activities, refinery performance and product supply and demand.

The Coronavirus Disease 2019 (COVID-19) pandemic continues to disrupt economic activities globally. Actions taken by governments to prevent the spread of the disease, including travel and business restrictions, have resulted in substantial decreases in the demand for many refined petroleum products, particularly gasoline and jet fuel. Demand for refined petroleum products started to recover following the distribution of COVID-19 vaccines at the beginning of 2021, and consequently, refining margins have improved. Ongoing market discipline of OPEC producers has reduced excess supplies of crude oil and the current balance has supported higher crude oil and NGL prices. During the first quarter of 2021, however, winter storms significantly impacted the Central and Gulf Coast regions, which resulted in reduced throughput volumes on both our and our joint ventures’ assets, as well as higher costs.

Our customers, including Phillips 66, may continue to experience adverse economic effects in the near term as the depth and duration of the economic consequences of the COVID-19 pandemic remain uncertain. We continuously monitor our asset and investment portfolio for impairments in this challenging business environment. We recorded an impairment totaling $198 million in the first quarter of 2021, and additional impairments may be required in the future.

While we believe we and the majority of our joint ventures have substantially mitigated our indirect exposure to commodity price fluctuations through the minimum volume commitments included in our commercial agreements, our ability to execute our strategy will depend, in part, on the availability of attractively priced crude oil in the areas served by our crude oil pipelines and rail racks, demand for refined petroleum products in the markets served by our refined petroleum product pipelines and terminals, and the general demand for midstream services, including NGL transportation and fractionation.

Statement of Income (Loss) Analysis

Operating revenues decreased $15 million, or 6%, in the first quarter of 2021. The decrease was primarily attributable to reduced volumes resulting from market demand and the effects of winter storms impacting the Central and Gulf Coast regions, partially offset by additional assets placed in operation, including additional storage capacity at the Clemens Caverns in mid-2020.

Equity in earnings of affiliates decreased $12 million, or 9% in the first quarter of 2021. The decrease was primarily due to reduced volumes, partially offset by an increase in equity earnings from Gray Oak Pipeline, LLC, which commenced full operations during the second quarter of 2020, and South Texas Gateway Terminal, which commenced partial operations in the third quarter of 2020. See Note 4—Equity Investments, in the Notes to Consolidated Financial Statements, for additional information.

Operating and maintenance expenses increased $7 million, or 8%, in the first quarter of 2021. The increase was primarily due to higher utility costs as a result of winter storms impacting the Central and Gulf Coast regions.

CAPITAL RESOURCES AND LIQUIDITY
Significant Sources of Capital
Our sources of liquidity include cash generated from operations, distributions from our equity affiliates, borrowings from related parties and under our revolving credit facility, issuances of additional debt and equity securities, and funding from joint venture partners. We believe that cash generated from these sources will be sufficient to meet our short-term working capital requirements, long-term capital expenditure requirements and our quarterly cash distributions.

Operating Activities
We generated $227 million in cash from operations during the first three months of 2021, a decrease of $47 million compared with the corresponding period of 2020. The decrease was primarily driven by lower operating revenue, higher operating and maintenance expenses, and lower operating distributions from equity affiliates.

Equity Affiliate Distributions
Our operating and investing cash flows are impacted by distribution decisions made by our equity affiliates. During the first three months of 2021, we received aggregate distributions from our equity affiliates of $158 million, compared with $178 million during the same period of 2020. We cannot control the amount or timing of future distributions from equity affiliates; therefore, future distributions are not assured.

Revolving Credit Facility
At March 31, 2021, and December 31, 2020, borrowings of $450 million and $415 million were outstanding under our $750 million revolving credit facility, respectively. At both March 31, 2021, and December 31, 2020, $1 million in letters of credit had been issued that were supported by this facility.

Debt Issuance
On April 6, 2021, we entered into a $450 million term loan agreement and borrowed the full amount. The term loan agreement has a maturity date of April 5, 2022, and the outstanding borrowings can be repaid at any time and from time to time, in whole or in part, without premium or penalty. Borrowings bear interest at a floating rate based on either a Eurodollar rate or a reference rate, plus a margin of 0.875%. Proceeds were primarily used to repay amounts borrowed under our $750 million revolving credit facility.

ATM Program
We have authorized an aggregate of $750 million under three $250 million continuous offerings of common units, or at-the-market (ATM) programs. The first two programs concluded in June 2018 and December 2019, respectively. We suspended issuances under the ATM program in the first quarter of 2020 due to low common unit prices. We did not issue any common units under the current ATM program during the three months ended March 31, 2021.

Off-Balance Sheet Arrangements

Dakota Access, LLC (Dakota Access) and Energy Transfer Crude Oil Company, LLC (ETCO)
In March 2019, a wholly owned subsidiary of Dakota Access issued $2.5 billion aggregate principal amount of senior unsecured notes. Dakota Access and ETCO have guaranteed repayment of the notes.  In addition, we and our co-venturers in Dakota Access provided a Contingent Equity Contribution Undertaking (CECU) in conjunction with the notes offering.  Under the CECU, the co-venturers may be severally required to make proportionate equity contributions to Dakota Access if there is an unfavorable final judgment in the ongoing litigation related to an easement granted by the U.S. Army Corps of Engineers (USACE) to allow the pipeline to be constructed under Lake Oahe in North Dakota. Contributions may be required if Dakota Access determines that the issues included in any such final judgment cannot be remediated and Dakota Access has or is projected to have insufficient funds to satisfy repayment of the notes. If Dakota Access undertakes remediation to cure issues raised in a final judgment, contributions may be required if any series of the notes become due, whether by acceleration or at maturity, during such time, to the extent Dakota Access has or is projected to have insufficient funds to pay such amounts. At March 31, 2021, our share of the maximum potential equity contributions under the CECU was approximately $631 million.

In July 2020, the trial court presiding over the litigation vacated Dakota Access’ easement under Lake Oahe and ordered the Dakota Access Pipeline to be shut down and emptied of crude oil pending the preparation of an Environmental Impact Statement (EIS) by the USACE, which had been ordered by the court in March 2020 and is now expected to be completed by March 2022. In August 2020, pending an appeal of the trial court’s decisions, an appellate court denied Dakota Access’ motion to stay the order vacating the easement, but granted its motion to stay the order that the pipeline be shut down while the EIS is prepared. In January 2021, the appellate court affirmed the trial court’s order vacating the easement and directing the USACE to prepare an EIS and reversed the order directing the pipeline to be shut down. Notwithstanding that the easement has been vacated, in April 2021, the USACE indicated that it currently intends to allow the pipeline to continue to operate while it proceeds with the EIS. Currently, there is a motion for a permanent injunction to shut down the pipeline before the trial court that could be decided at any time. Additionally, Dakota Access has requested the appellate court to stay its January 2021 decision pending a filing and disposition of a petition for writ of certiorari to the U.S. Supreme Court.

If the pipeline is required to cease operations, either permanently or pending the preparation of the EIS, and should Dakota Access and ETCO not have sufficient funds to pay ongoing expenses, we also could be required to support our share of the ongoing expenses, including scheduled interest payments on the notes of approximately $25 million annually, in addition to the potential obligations under the CECU. If we are required to perform under the CECU, we would expect to fund such performance with cash, capacity available under our revolving credit facility, third-party debt financing, and/or sponsor loans from Phillips 66.


Capital Requirements

Capital Expenditures and Investments
Our operations are capital intensive and require investments to expand, upgrade, maintain or enhance existing operations and to meet environmental and operational requirements of our wholly owned and joint venture entities. Our capital requirements consist of maintenance and expansion capital expenditures, as well as contributions to our joint ventures. Maintenance capital expenditures are those made to replace partially or fully depreciated assets, to maintain the existing operating capacity of our assets and to extend their useful lives, or to maintain existing system volumes and related cash flows. In contrast, expansion capital expenditures are those made to expand and upgrade our systems and facilities and to construct or acquire new systems or facilities to grow our business, including contributions to joint ventures that are using the contributed funds for such purposes.

Our capital expenditures and investments represent the total spending for our capital requirements. Our adjusted capital spending is a non-GAAP financial measure that demonstrates our net share of capital spending, and reflects an adjustment for the portion of consolidated capital spending funded by certain joint venture partners. Additionally, the disaggregation of adjusted capital spending between expansion and maintenance is not a distinction recognized under GAAP. We disaggregate adjusted capital spending because our partnership agreement requires that we treat expansion and maintenance capital differently for operating and capital surplus determinations. Further, we generally fund expansion capital spending with both operating and financing cash flows and fund maintenance capital spending with operating cash flows.

Spending associated with other return, reliability and maintenance projects.


Cash Distributions
On April 20, 2021, the Board of Directors of our General Partner declared a quarterly cash distribution of $0.875 per common unit, which will result in a total distribution of $200 million attributable to the first quarter of 2021. This distribution is payable on May 14, 2021, to common unitholders of record as of April 30, 2021.

Beginning with the distribution to preferred unitholders attributable to the fourth quarter of 2020, the preferred unitholders are entitled to receive cumulative quarterly distributions equal to the greater of $0.678375 per unit, or the per-unit distribution amount paid to the common unitholders. Preferred unitholders will receive $12 million of distributions attributable to the first quarter of 2021. This distribution is payable May 14, 2021, to preferred unitholders of record as of April 30, 2021.

Debt Repayment
On April 1, 2021, we repaid the two remaining $25 million tranches of tax-exempt bonds due April 2021, totaling $50 million.

From time to time, lawsuits involving a variety of claims that arise in the ordinary course of business are filed against us. We also may be required to remove or mitigate the effects on the environment of the placement, storage, disposal or release of certain chemical, mineral and petroleum substances at various sites. We regularly assess the need for accounting recognition or disclosure of these contingencies. In the case of all known contingencies (other than those related to income taxes), we accrue a liability when the loss is probable and the amount is reasonably estimable. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not reduce these liabilities for potential insurance or third-party recoveries. If applicable, we accrue receivables for probable insurance or other third-party recoveries. In the case of income-tax-related contingencies, we use a cumulative probability-weighted loss accrual in cases where sustaining a tax position is uncertain.

Based on currently available information, we believe it is remote that future costs related to known contingent liability exposures will exceed current accruals by an amount that would have a material adverse impact on our consolidated financial statements. As we learn new facts concerning contingencies, we reassess our position both with respect to accrued liabilities and other potential exposures. Estimates particularly sensitive to future changes include any contingent liabilities recorded for environmental remediation, tax and legal matters. Estimated future environmental remediation costs are subject to change due to such factors as the uncertain magnitude of cleanup costs, the unknown time and extent of such remedial actions that may be required, and the determination of our liability in proportion to that of other potentially responsible parties. Estimated future costs related to tax and legal matters are subject to change as events evolve and as additional information becomes available during the administrative and litigation processes.

Regulatory Matters
Our interstate common carrier crude oil and refined petroleum products pipeline operations are subject to rate regulation by the Federal Energy Regulatory Commission under the Interstate Commerce Act and Energy Policy Act of 1992, and certain of our pipeline systems providing intrastate service are subject to rate regulation by applicable state authorities under their respective laws and regulations. Our pipeline, rail rack and terminal operations are also subject to safety regulations adopted by the Department of Transportation, as well as to state regulations.

Legal and Tax Matters
Under our amended omnibus agreement, Phillips 66 provides certain services for our benefit, including legal and tax support services, and we pay an operational and administrative support fee for these services. Phillips 66’s legal and tax organizations apply their knowledge, experience and professional judgment to the specific characteristics of our cases and uncertain tax positions. Phillips 66’s legal organization employs a litigation management process to manage and monitor the legal proceedings against us. The process facilitates the early evaluation and quantification of potential exposures in individual cases and enables tracking of those cases that have been scheduled for trial and/or mediation. Based on professional judgment and experience in using these litigation management tools and available information about current developments in all our cases, Phillips 66’s legal organization regularly assesses the adequacy of current accruals and recommends if adjustment of existing accruals, or establishment of new accruals, is required. As of March 31, 2021, and December 31, 2020, we did not have any material accrued contingent liabilities associated with litigation matters.

Environmental
We are subject to extensive federal, state and local environmental laws and regulations. These requirements, which frequently change, regulate the discharge of materials into the environment or otherwise relate to protection of the environment. Compliance with these laws and regulations may require us to remediate environmental damage from any discharge of petroleum or chemical substances from our facilities or require us to install additional pollution control equipment at or on our facilities. Our failure to comply with these or any other environmental or safety-related regulations could result in the assessment of administrative, civil, or criminal penalties, the imposition of investigatory and remedial liabilities, and the issuance of governmental orders that may subject us to additional operational constraints. Future expenditures may be required to comply with the Federal Clean Air Act and other federal, state and local requirements in respect of our various sites, including our pipelines and storage assets. The impact of legislative and regulatory developments, if enacted or adopted, could result in increased compliance costs and additional operating restrictions on our business, each of which could have an adverse impact on our financial position, results of operations and liquidity.

As with all costs, if these expenditures are not ultimately recovered in the tariffs and other fees we receive for our services, our operating results will be adversely affected. We believe that substantially all similarly situated parties and holders of comparable assets must comply with similar environmental laws and regulations. However, the specific impact on each may vary depending on a number of factors, including, but not limited to, the age and location of its operating facilities.

Table of Contents
We accrue for environmental remediation activities when the responsibility to remediate is probable and the amount of associated costs can be reasonably estimated. As environmental remediation matters proceed toward ultimate resolution or as additional remediation obligations arise, charges in excess of those previously accrued may be required. New or expanded environmental requirements, which could increase our environmental costs, may arise in the future. We believe we are in substantial compliance with all legal obligations regarding the environment and have established the environmental accruals that are currently required; however, it is not possible to predict all of the ultimate costs of compliance, including remediation costs that may be incurred and penalties that may be imposed, because not all of the costs are fixed or presently determinable (even under existing legislation) and the costs may be affected by future legislation or regulations.

Indemnification and Excluded Liabilities
Under our amended omnibus agreement and pursuant to the terms of various agreements under which we acquired assets from Phillips 66, Phillips 66 will indemnify us, or assume responsibility, for certain environmental liabilities, tax liabilities, litigation and any other liabilities attributable to the ownership or operation of the assets contributed to us and that arose prior to the effective date of each acquisition. These indemnifications and exclusions from liability have, in some cases, time limits and deductibles. When Phillips 66 performs under any of these indemnifications or exclusions from liability, we recognize non-cash expenses and associated non-cash capital contributions from our General Partner, as these are considered liabilities paid for by a principal unitholder.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This report includes forward-looking statements. You can normally identify our forward-looking statements by the words “anticipate,” “estimate,” “believe,” “budget,” “continue,” “could,” “intend,” “may,” “plan,” “potential,” “predict,” “seek,” “should,” “will,” “would,” “expect,” “objective,” “projection,” “forecast,” “goal,” “guidance,” “outlook,” “effort,” “target” and similar expressions, although the absence of these words does not mean that statement is not forward-looking.

We based the forward-looking statements on our current expectations, estimates and projections about us, our operations, the operations of our joint ventures and the entities in which we own equity interests, as well as the industries in which we and they operate in general. We caution you these statements are not guarantees of future performance as they involve assumptions that, while made in good faith, may prove to be incorrect, and involve risks and uncertainties we cannot predict. In addition, we based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. Accordingly, our actual outcomes and results may differ materially from what we have expressed or forecast in the forward-looking statements. Any differences could result from a variety of factors, including the following:

The continuing effects of the COVID-19 pandemic and its negative impact on the demand for crude oil and refined petroleum products, as well as the extent and duration of recovery of economies and the demand for crude oil and refined petroleum products after the pandemic subsides.
Reductions in the volume of crude oil, refined petroleum products and NGL we or our equity affiliates transport, fractionate, process, terminal and store.
The continued ability of Phillips 66 to satisfy its obligations under our commercial and other agreements.
Fluctuations in the prices and demand for crude oil, refined petroleum products and NGL, including as a result of actions taken by OPEC and other countries impacting supply and demand and, correspondingly, commodity prices.
Changes in governmental policies relating to crude oil, refined petroleum products or NGL pricing, regulation, taxation, or exports.
Potential liabilities associated with the risks and operational hazards inherent in transporting, fractionating, processing, terminaling and storing crude oil, refined petroleum products and NGL.
Curtailment of operations due to severe weather (including as a result of climate change) disruption or natural disasters; riots, strikes, lockouts or other industrial disturbances.
Accidents or other unscheduled shutdowns affecting our pipelines, processing, fractionating, terminaling, and storage facilities or equipment, or those of our equity affiliates, suppliers or customers.
Our, and our equity affiliates’, inability to obtain or maintain permits, in a timely manner, or at all, and the possibility of the revocation or modification of such permits.
The operation, financing and distribution decisions of our joint ventures, which we may not control.
The inability to comply with government regulations or make capital expenditures required to maintain compliance.
The failure to complete construction of announced and future capital projects in a timely manner, cost overruns associated with such projects, and the ability to obtain or maintain permits necessary for such projects.
Our ability to successfully execute our growth strategies, whether through organic growth or acquisitions.
Costs or liabilities associated with federal, state, and local laws and regulations relating to environmental protection and safety, including spills, releases and pipeline integrity.
Failure of information technology systems due to various causes, including unauthorized access or attack.
Changes to the tariff rates with respect to volumes transported through regulated assets, which rates are subject to review and possible adjustment by federal and state regulators.
Changes in revenue we realize under the loss allowance provisions of our regulated tariffs resulting from changes in underlying commodity prices.
Costs associated with compliance with evolving environmental laws and regulations on climate change.
