The consolidated financial results of WES Operating are included in the Partnership’s consolidated financial statements. Throughout these notes to consolidated financial statements, and to the extent material, any differences between the consolidated financial results of the Partnership and WES Operating are discussed separately. The Partnership’s consolidated financial statements differ from those of WES Operating primarily as a result of (i) the presentation of noncontrolling interest ownership (see Noncontrolling interests below and Note 5)below), (ii) the elimination of WES Operating GP’s investment in WES Operating with WES Operating GP’s underlying capital account, (iii) the general and administrative expenses incurred by the Partnership, which are separate from, and in addition to, those incurred by WES Operating, (iv) the inclusion of the impact of Partnership equity balances and Partnership distributions, and (v) transactions between the senior secured revolving credit facility (“WGP RCF”) until its repayment in March 2019. See Note 11.Partnership and WES Operating that eliminate upon consolidation.

The Partnership’s assets include assets owned and ownership interests accounted for by the Partnership under the equity method of accounting, through its 98.0% partnership interest in WES Operating, as of September 30, 20202021 (see Note 7). The Partnership also owns and controls the entire non-economicnon-economic general partner interest in WES Operating GP, and the Partnership’s general partner is owned by Occidental.

Use of estimates. In preparing financial statements in accordance with GAAP, management makes informed judgments and estimates that affect the reported amounts of assets, liabilities, revenues, and expenses. Management evaluates its estimates and related assumptions regularly, using historical experience and other reasonable methods. Changes in facts and circumstances or additional information may result in revised estimates, and actual results may differ from these estimates. Effects on the business, financial condition, and results of operations resulting from revisions to estimates are recognized when the facts that give rise to the revisions become known. The information included herein reflects all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the consolidated financial statements, and certain prior-period amounts have been reclassified to conform to the current-year presentation.statements.

Noncontrolling interests. For periods subsequent to Merger completion, theThe Partnership’s noncontrolling interests in the consolidated financial statements consist of (i) the 25% third-partythird-party interest in Chipeta and (ii) the 2.0% Occidental subsidiary-ownedsubsidiary-owned limited partner interest in WES Operating. For periods prior to Merger completion, the Partnership’s noncontrolling interests in the consolidated financial statements consisted of (i) the 25% third-party interest in Chipeta, (ii) the publicly held limited partner interests in WES Operating, (iii) the common units issued by WES Operating to subsidiaries of Anadarko as part of the consideration paid for prior-period acquisitions from Anadarko, and (iv) the Class C units issued by WES Operating to a subsidiary of Anadarko as part of the funding for the acquisition of DBM. For all periods presented, WES Operating’s noncontrolling interest in the consolidated financial statements consists of the 25% third-partythird-party interest in Chipeta. See Note 5.
When WES Operating issues equity, the carrying amount of the noncontrolling interest reported by the Partnership is adjusted to reflect the noncontrolling ownership interest in WES Operating.

Inventory. The cost of NGLs inventory is determined by the weighted-average cost method on a location-by-location basis. Inventory is stated at the lower of weighted-average cost or net realizable value. NGLs inventory is reported in Other current assets and NGLs line-fill inventory is reported in Other assets on the consolidated balance sheets. Materials and supplies inventory is valued at weighted-average cost and is reviewed periodically for obsolescence.

Shutdown of gathering systems. In May 2018, after assessing a number of factors, and with the safety of the community and the protection of the environment as primary factors, the Partnership permanently ceased operations at the Kitty Draw gathering system in Wyoming (part of the Hilight system) and the Third Creek gathering system in Colorado (part of the DJ Basin complex). An accrual of $10.9 million for anticipated costs associated with system shutdowns was recorded in 2018 as a reduction in related-party Product sales in the consolidated statements of operations. During the nine months ended September 30, 2019, $6.1 million of the accrual related to the Kitty Draw gathering system was reversed due to producer settlements being less than their initial estimates.

Segments. The Partnership’s operations continue to be organized into a single operating segment, the assets of which gather, compress, treat, process, and transport natural gas; gather, stabilize, and transport condensate, NGLs, and crude oil; and gather and dispose of produced water in the United States.

Equity-based compensation. On February 10, 2020, the Board of Directors approved awards of phantom units (the “Awards”) to the Partnership’s executive officers under the Western Gas Equity Partners, LP 2012 Long-Term Incentive Plan (“WES LTIP”). The Awards include (i) an award of time-vested phantom units that vest ratably over a three-year period (“Time-Based Awards”), (ii) a market award that vests after a three-year performance period based on the Partnership’s relative total unitholder return as compared to a group of peer companies (“TUR Awards”), and (iii) a performance award that vests based on the Partnership’s average return on assets over a three-year performance period (“ROA Awards”). At vesting, the value of the TUR Awards and the ROA Awards will be determined in accordance with the terms of the respective Award Agreements that provide for payout percentages ranging from 0% to 200% based on results achieved over the applicable performance period. At vesting, the Awards generally will be settled in Partnership common units. Prior to vesting, the Awards pay in-kind distributions in the form of Partnership common units. During the nine months ended September 30, 2020,2021, the Partnership issued 80,081357,472 common units as in-kind distributions under such Awards.
In addition, phantom units are awarded under the WES LTIP to non-executive employees and independent directors of the Partnership from time to time, which vest ratably over a three-year period and one year from the grant date, respectively. Prior to vesting, the awards to non-executive employees and independent directors pay distribution equivalents in cash.
The equity-based compensation expense attributable to these awards is amortized over the vesting periods applicable to the awards using the straight-line method. Expense is recognized based on the grant-date fair value and recorded, net of any forfeitures, as General and administrative expense in the consolidated statements of operations. The fair value of the Time-based Awards, ROA Awards, and non-executive awards is based on the observable market price of the Partnership’s units on the grant date of the award. The fair value of the TUR Awards is determined using a Monte Carlo simulation at the grant date of the award. For ROA Awards, all performance-related fair-value changes are recognized in compensation expense during the performance period.its long-term incentive plans. Compensation expense was $4.7 million and $12.9 million for the WES LTIP wasthree and nine months ended September 30, 2021, respectively, and $2.1 million and $5.4 million for the three and nine months ended September 30, 2020, respectively, and $0.6 million and $1.0 millionrespectively.
On March 22, 2021, the Board of Directors approved the Western Midstream Partners, LP 2021 Long-Term Incentive Plan (the “2021 LTIP”). Subject to the capitalization adjustment provisions included in the 2021 LTIP, the total aggregate number of common units that may be delivered with respect to awards under the 2021 LTIP is 9,500,000 (the “2021 LTIP Limit”). Common units withheld from an award or surrendered by a participant to satisfy tax withholding obligations or to satisfy the payment of any exercise price with respect to an award will not be considered to be common units delivered under the 2021 LTIP for purposes of the 2021 LTIP Limit. If any award is forfeited, cancelled, exercised, settled in cash, or otherwise terminates or expires without the actual delivery of common units, the common units subject to such award will again be available for awards under the 2021 LTIP.

1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION (CONTINUED)

Recently adopted accounting standards. Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326) significantly changes the accounting and disclosure requirements related to credit losses on financial assets. Under the new standard, entities are now required to estimate lifetime expected credit losses for trade receivables, loans, and other financial instruments as of the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts, resulting in earlier recognition of credit losses. There was no impact to the consolidated financial statements with the Partnership’s adoption of the standard on January 1, 2020. The Partnership has implemented the necessary changes to its processes and controls to support accounting and disclosure requirements under this ASU.

Accounts receivable and contract assets. Accounts receivable represent contractual rights for services performed, with, on average, 30-day payment terms from the date of invoice. Contract assets primarily relate to revenue accrued but not yet billed under cost-of-service contracts and accrued deficiency fees. As of September 30, 2020, there have been no negative indications regarding the collectability of significant receivables as it relates to impacts from the global outbreak of the coronavirus (“COVID-19”) and the oil-market disruption resulting from significantly lower global demand and corresponding oversupply of crude oil. The Partnership will continue to monitor the credit quality of its customer base and assess collectability of these assets as appropriate.respectively.

Certain of the Partnership’s midstream services contracts have minimum-volume commitment demand fees and fees that require periodic rate redeterminations based on the related facility cost-of-service rate provisions. During the year ended December 31, 2020, and the six months ended June 30, 2021, the Partnership constrained revenue on certain cost-of-service agreements based on the status of commercial negotiations relating to a legal dispute with one of the contract counterparties. During the three months ended September 30, 2021, the Partnership determined it was no longer necessary to constrain revenue under these cost-of-service agreements. The Partnership updated its estimate of variable consideration and a cumulative catch-up revenue adjustment of $18.9 million was recorded to Service revenues – fee based. Future revenue reversals could occur to the extent the outcome of the legal proceedings and commercial negotiations differ from our current assumptions.

Where AESC sold natural gas and NGLs on the Partnership’s customers’ behalf, the Partnership recognized associated service revenues and cost of product expense for the marketing services performed by AESC. When product sales were on the Partnership’s behalf, the Partnership recognized product sales revenues based on Occidental’s sales price to the third party and recorded the associated cost of product expense associated with the marketing activities provided by AESC. Effective April 1, 2020, changes to marketing-contractmarketing-contract terms with AESC terminated AESC’s prior status as an agent of the Partnership for third-partythird-party sales and established AESC as a customer of the Partnership.

7. EQUITY INVESTMENTS (CONTINUED)

The investment balance in Ranch Westex at September 30, 2020,2021, was $25.3$37.1 million less than the Partnership’s underlying equity in Ranch Westex’s net assets primarily due toassets. During the nine months ended September 30, 2021, the Partnership recognized an impairment loss recognized by the Partnership in the third quarter of 2020. The impairment loss of $29.4$11.8 million that resulted from a decline in value below the carrying value, which was determined to be other than temporary in nature. This investment was impaired to its estimated fair value of $16.7$2.9 million, using the income approach and Level-3 fair value inputs, due to a reduction in estimated future cash flows resulting from lower forecasted producer throughput.
The investment balance in Saddlehorn at September 30, 2020, was $14.1 million less than the Partnership’s underlying equity in Saddlehorn’s net assets, primarily due to income from an expansion project that was funded by Saddlehorn’s other owners being disproportionately allocated to the Partnership beginning in the second quarter of 2020. This difference will be amortized to Equity income, net – related parties in the consolidated statements of operations over the remaining estimated useful life of the Saddlehorn pipeline.

Long-lived asset and other impairments. During the nine months ended September 30, 2021, the Partnership recognized impairments of $29.2 million, primarily attributable to (i) $14.1 million of impairments at the DJ Basin complex due to cancellation of projects and (ii) an $11.8 million other-than-temporary impairment of the Partnership’s investment in Ranch Westex (see Note 7).
During the nine months ended September 30, 2020, the Partnership recognized impairments of $200.6 million, primarily due to $150.2 million of impairments for assets located in Wyoming and Utah. These assets were impaired to estimated fair values of $112.2 million. The Partnership assesses whether events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The fair value of assets with impairment triggers were measured using the income approach and Level-3Level-3 fair value inputs. The income approach was based on the Partnership’s projected future earnings before interest, taxes, depreciation, and amortization (“EBITDA”) and free cash flows, which requires significant assumptions including, among others, future throughput volumes based on current expectations of producer activity and operating costs. These impairments were primarily triggered by reductions in estimated future cash flows resulting from lower forecasted producer throughput and lower commodity prices. The remaining impairments of $21.0 million were primarily at the DJ Basin complex and DBM water systems due to the cancellation of projects and impairments of rights-of-way.rights

8. PROPERTY, PLANT, AND EQUIPMENT (CONTINUED)

During the year ended December 31, 2019, the Partnership recognized impairments of $6.3 million, primarily at the DJ Basin complex due to impairments of rights-of-way and cancellation of projects.

Potential future long-lived asset impairments. As of September 30, 2020,2021, it is reasonably possible that future commodity-price declines, prolonged lowdepression of commodity prices, further commodity-price declines, changes to producers’ drilling plans in response to lower prices, and potential producer bankruptcies could result in future long-livedlong-lived asset impairments. For example, on April 29, 2020, the Partnership received notice that Sanchez, in its bankruptcy, was seeking to reject a number of midstream and downstream agreements with commercial counterparties, including Sanchez’s Springfield gathering agreements and agreements obligating Sanchez to deliver the gas volumes gathered by the Springfield system to our Brasada processing plant. On May 6, 2021, the Bankruptcy Court issued an opinion determining, among other things, that Sanchez’s Springfield gathering agreements were rejected, but that such agreements contain covenants running with the land that survive rejection, thus preserving the acreage dedication to the Partnership’s Springfield system. Depending on the ultimate outcome of the Partnership’s continuing efforts to defend its contractual rights in the bankruptcy proceeding, as well as the Partnership’s ongoing commercial discussions, the Partnership’s South Texas assets could be impaired.

9. GOODWILL

Goodwill is recorded when the purchase price of a business acquired exceeds the fair market value of the tangible and separately measurable intangible net assets. Goodwill also includes the allocated historic carrying value of midstream goodwill attributed to the Partnership’s assets previously acquired from Anadarko. The Partnership’s goodwill has been allocated to 2 reporting units: (i) gathering and processing and (ii) transportation.
The Partnership evaluates goodwill for impairment annually,at the reporting-unit level on an annual basis, as of October 1, or more often as facts and circumstances warrant. An initial qualitative assessment is performed to determine the likelihood of whether goodwill is impaired and if deemed necessary based on this assessment, a quantitative assessment is then performed. If the quantitative assessment indicates that the carrying amountvalue of the reporting unit, including goodwill, exceeds its fair value, a goodwill impairment is recorded for the amount by which the reporting unit’s carrying value exceeds its fair value.
During the three months ended March 31, 2020, the Partnership performed an interim goodwill impairment test due to a significant decline in the trading price of the Partnership’s common units, triggered by the combined impacts from the global outbreak of COVID-19COVID-19 and the oil-marketoil-market disruption resulting from significantly lower global demand and corresponding oversupply of crude oil. The Partnership primarily used the market approach and Level-3Level-3 inputs to estimate the fair value of its two reporting units. The market approach was based on multiples of EBITDA and the Partnership’s projected future EBITDA. The EBITDA multiples were based on current and historic multiples for comparable midstream companies of similar size and business profit to the Partnership. The EBITDA projections require significant assumptions including, among others, future throughput volumes based on current expectations of producer activity and operating costs. The reasonableness of the market approach was tested against an income approach that was based on a discounted cash-flowcash-flow analysis. Key assumptions in this analysis include the use of an appropriate discount rate, terminal-yearterminal-year multiples, and estimated future cash flows, including estimates of throughput, capital expenditures, operating, and general and administrative costs. The Partnership also reviewed the reasonableness of the total fair value of both reporting units to the market capitalization as of March 31, 2020, and the reasonableness of an implied acquisition premium. Impairment determinations involve significant assumptions and judgments, and differing assumptions regarding any of these inputs could have a significant effect on the valuations. As a result of the interim impairment test, the Partnership recognized a goodwill impairment of $441.0 million during the first quarter of 2020, which reduced the carrying amountvalue of goodwill to 0 for the gathering and processing reporting unit.unit to zero. Goodwill allocated to the transportation reporting unit of $4.8 million as of March 31, 2020, was not impaired. Recurring goodwill impairment assessments have indicated no further impairment.

Weather-related impacts. In February 2021, the U.S. experienced winter storm Uri, bringing extreme cold temperatures, ice, and snow to the central U.S., including Texas, and in March 2021, Colorado experienced a historic blizzard. Winter storm Uri adversely affected our volumes for approximately ten days and the blizzard in Colorado likewise disrupted our assets in that state. We estimate the impact of these weather events to have reduced net income and Adjusted EBITDA (as defined under the caption Key Performance Metrics within this Item 2) for the nine months ended September 30, 2021, by approximately $30 million due to lower volumes, the impact of commodity-prices, and higher operating expenses related to utilities. The estimated impact of the adverse winter weather on our operations and financial results may change and those changes may be material. Any additional inclement weather in the future, or other adverse conditions, including resolution of litigation and other legal disputes and the COVID-19 pandemic and resulting mitigation factors, may have an adverse impact on our operations and financial results.

COVID-19. During 2020, the global outbreak of COVID-19COVID-19 caused a sharp decline in the worldwide demand for oil, natural gas, and NGLs, which contributed significantly to recent commodity-pricecommodity-price declines and oversupplied commodities markets. These market dynamics have had an adverse impact on producers that provide throughput into our systems, and we have experienced decreased throughput at many of our locations, which may adversely affect our results of operations and cash flows.locations.
Additionally, many of our employees have been and may continue to be subject to pandemic-related work-from-homepandemic-related work-from-home requirements, which requiresrequire us to take additional actions to ensure that the number of personnel accessing our network remotely does not lead to excessive cyber-securitycyber-security risk levels during the ongoing work-from-home precautionary phase of the pandemic.levels. Similarly, we are working continually to ensure operational changes that we have made to promote the health and safety of our personnel during this pandemic do not unduly disrupt intracompany communications and key business processes. We consider our risk-mitigationrisk-mitigation efforts adequate; however, the ultimate impact of the ongoing pandemic is unpredictable, with direct and indirect impacts to our business. See Risk Factors under Part II, Item 1A of this Form 10-Q for additional information on these and other risks.
WES continues to monitor the COVID-19COVID-19 situation closely, and as state and federal governments issue additional guidance, we will update our own policy responsespolicies in response to ensure the safety and health of our workforce and communities. The federal government has provided guidance to states on how to safely return personnel to the workplace, which we are following as our workforce returns to WES locations. All WES facilities, including field locations, have been conducting enhanced routine cleaning and disinfecting of common areas and frequently touched surfaces using CDC-CDC- and EPA-approvedEPA-approved products. Our return-to-workreturn-to-work protocols include daily required application-basedapplication-based health self-assessmentsself-assessments that must be completed prior to accessing WES work locations.

OUTLOOK

We expect our business to continue to be affected by the below-describedbelow-described key trends and uncertainties. Our expectations are based on assumptions made by us and information currently available to us. To the extent our underlying assumptions about, or interpretations of, available information prove incorrect, our actual results may vary materially from expected results. Read Risk Factors under Part II, Item 1A of this Form 10-Q for additional information.

Impact of crude-oil, natural-gas, and NGLs prices. Crude-oil, natural-gas,Crude-oil, natural-gas, and NGLs prices can fluctuate significantly, and have done so over time. Commodity-priceCommodity-price fluctuations affect the level of our customers’ activities and our customers’ allocations of capital within their own asset portfolios. During the first quarter of 2020, oil and natural-gasnatural-gas prices decreased significantly, driven by the expectation of increased supply and sharp declines in demand resulting from the worldwide macroeconomic downturn that followed the global outbreak of COVID-19.COVID-19. For example, NYMEX West Texas Intermediate crude-oilcrude-oil daily settlement prices recently ranged from a high of $63.27 per barrel in January 2020 to a low below $20.00 per barrel in April 2020, with2020. Although commodity prices reboundinghave rebounded to $40.22 per barrel at September 30, 2020. Whilepre-pandemic levels, the extent and duration of the recent commodity-price declinescommodity-price volatility cannot be predicted, and potential impacts to our business include the following:

We have exposure to increased credit risk to the extent any of our customers, including Occidental, is in financial distress. See Liquidity and Capital Resources—Credit risk within this Item 2 for additional information.

An extended period of diminished earnings may restrict our ability to fully access our RCF, which contains various customary covenants, certain events of default, and a maximum consolidated leverage ratio based on Adjusted EBITDA (as defined in the covenant) related to the trailing twelve-monthtwelve-month period. Further, any future waivers or amendments to the RCF also may trigger pricing increases for available credit. See Liquidity and Capital Resources—Debt and credit facilities within this Item 2 for additional information.

As of September 30, 2020,2021, it is reasonably possible that future commodity-price declines, prolonged lowdepression of commodity prices, further commodity-price declines, changes to producers’ drilling plans in response to lower prices, and potential producer bankruptcies could result in future long-livedlong-lived asset impairments.

To the extent producers continue with development plans in our areas of operation, we will continue to connect new wells or production facilities to our systems to maintain throughput on our systems and mitigate the impact of production declines. However, our success in connecting additional wells or production facilities is dependent on the activity levels of our customers. Additionally, we will continue to evaluate the crude-oil,crude-oil, NGLs, and natural-gasnatural-gas price environments and adjust our capital spending plans to reflect our customers’ anticipated activity levels, while maintaining appropriate liquidity and financial flexibility. See Risk Factor, “The global outbreak of COVID-19 is likely to have an adverse impact on our operations and financial results.” under Part II, Item 1A of this Form 10-Q for additional information.

Effects of credit-rating downgrade.Our costs of borrowing and ability to access the capital markets are affected by market conditions and the credit ratings assigned to WES Operating’s debt by the major credit rating agencies. In March 2020, Fitch Ratings (“Fitch”) and Standard and Poor’s (“S&P”) downgraded WES Operating’s long-term debt from “BBB-” to “BB+,” with negative watches assigned to each of these revised ratings. In May 2020, Fitch downgraded WES Operating’s long-term debt to “BB” and in June 2020, Moody’s Investors Service (“Moody’s”) downgraded WES Operating’s long-term debt from “Ba1” to “Ba2.” As a result of these downgrades, WES Operating’s credit rating is below investment grade for all three major credit rating agencies, which results in the following:

WES Operating’s annualized borrowing costs will increase by $34.6 million for the Fixed-Rate Senior Notes and Floating-Rate Senior Notes issued in January 2020 that provide for increased interest rates following downgrade events.

Beginning in the second quarter of 2020, the interest rate on outstanding RCF borrowings increased by 0.20% and the RCF facility-fee rate increased by 0.05%, from 0.20% to 0.25%.

We may be obligated to provide financial assurance of our performance under certain contractual arrangements requiring us to post collateral in the form of letters of credit or cash. At September 30, 2020, we had $5.0 million in letters of credit or cash-provided assurance of our performance outstanding under contractual arrangements with credit-risk-related contingent features.

Additional downgrades to WES Operating’s credit ratings will further impact its borrowing costs negatively, and may adversely affect WES Operating’s ability to issue public debt and effectively execute aspects of our business strategy.

Per-unit distribution reduction and revised capital guidance. During 2020, we announced the below-described per-unit distribution and cost reductions. These cash-preservation measures are intended to enhance our liquidity for the duration of the COVID-19 macroeconomic disruption and the weakened commodity-price environment; however, the duration and severity of this pandemic and concomitant economic downturn remains uncertain. There can be no assurance that these announced actions will provide sufficient liquidity for the required duration, and additional actions, including additional per-unit distribution reductions, may be necessary to manage through the current environment.

A quarterly cash distribution of $0.31100 per unit for the first quarter of 2020, which represents a 50% reduction to the distribution paid for the previous quarter. On October 20, 2020, we announced that our per-unit distribution for the third quarter of 2020 was unchanged from the first- and second-quarter 2020 $0.31100 per-unit distributions.

On April 20, 2020, we announced capital expenditures for the year ended December 31, 2020, were expected to be $450.0 million to $550.0 million, representing a 45% reduction to prior guidance. This reduction resulted from deferred producer activity in all basins and the elimination of associated capital expenditures, other than those expenditures that are necessary to support proper maintenance and long-term asset integrity. On August 10, 2020, we announced a further downward revision to our estimated full-year 2020 capital expenditures, which were expected to be $400.0 million to $450.0 million, representing a $75.0 million reduction to the April 2020 guidance midpoint of $500.0 million. On November 9, 2020, we announced that we expect our full-year capital expenditures to be meaningfully below the low-end of our previously updated 2020 guidance range of $400.0 million to $450.0 million.

On April 20, 2020, we announced expected other cost reductions of approximately $75.0 million through operating and maintenance and general and administrative expense cost-saving initiatives. On November 9, 2020, we announced that we expect to realize approximately $175.0 million in operating and maintenance and general and administrative expense cost savings.

Red Bluff Express acquisition. In January 2019, we acquired a 30% interest in Red Bluff Express, which owns a third-party-operated natural-gas pipeline connecting processing plants in Reeves and Loving Counties, Texas, to the WAHA hub in Pecos County, Texas. We acquired our 30% interest from a third party via an initial net investment of $92.5 million, which represented a 30% share of costs incurred up to the date of acquisition. The initial investment was funded with cash on hand and the interest in Red Bluff Express is accounted for under the equity method of accounting.DIVESTITURES

Fort Union and Bison facilities. In October 2020, we (i) sold our 14.81% interest in Fort Union, which was accounted for under the equity method of accounting, and (ii) entered into an option agreement to sell the Bison treating facility, during the first quarter of 2021, located in Northeast Wyoming, to a third party.
During the second quarter of 2021, the third party exercised its option to purchase the Bison treating facility and the sale closed. We received combinedtotal proceeds of $27.0$8.0 million, $7.0 million in the fourth quarter of 2020 and $1.0 million when the sale closed in the second quarter of 2021, resulting in a net gain on sale of $21.0$5.4 million related to the Fort Union interest that will bewas recorded as Gain (loss) on divestiture and other, net in the fourth quarterconsolidated statements of 2020. A gain related to the option agreement and potential sale of the Bison treating facility will be recognized in the first quarter of 2021 if the option is exercised or expires.

Presentation of the Partnership’s assets.Our assets include assets owned and ownership interests accounted for by us under the equity method of accounting, through our 98% partnership interest in WES Operating as of September 30, 2020 (seeoperations. See Note 7—Equity Investments3—Acquisitions and Divestitures in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q).

We are not a taxable entity for U.S. federal income tax purposes; therefore, our federal statutory rate is zero percent. However, income apportionable to Texas is subject to Texas margin tax.
For the nine months ended September 30, 2019,all periods presented, the variance from the federal statutory rate primarily was due to federal and state taxes on pre-acquisition income attributable to assets previously acquired from Anadarko, and our share of applicable Texas margin tax. For all other periods presented, the variance from the federal statutory rate was primarily due to our Texas margin tax liability.
Income attributable to the AMA assets prior to and including February 2019 was subject to federal and state income tax. Income earned on the AMA assets for periods subsequent to February 2019 was subject only to Texas margin tax on income apportionable to Texas.

Adjusted gross margin.We define Adjusted gross margin attributable to Western Midstream Partners, LP (“Adjusted gross margin”) as total revenues and other (less reimbursements for electricity-relatedelectricity-related expenses recorded as revenue), less cost of product, plus distributions from equity investments, and excluding the noncontrolling interestsinterest owners’ proportionate share of revenues and cost of product. We believe Adjusted gross margin is an important performance measure of our operations’ profitability and performance as compared to other companies in the midstream industry. Cost of product expenses include (i) costs associated with the purchase of natural gas and NGLs pursuant to our percent-of-proceeds, percent-of-product, and keep-whole contracts, (ii) costs associated with the valuation of gas and NGLs imbalances, and (iii) costs associated with our obligations under certain contracts to redeliver a volume of natural gas to shippers, which is thermally equivalent to condensate retained by us and sold to third parties.
To facilitate investor and industry analyst comparisons between us and our peers, we also disclose per-Mcf Adjusted gross margin for natural-gas assets, per-Bbl Adjusted gross margin for crude-oil and NGLs assets, and per-Bbl Adjusted gross margin for produced-water assets.

Adjusted EBITDA. We define Adjusted EBITDA attributable to Western Midstream Partners, LP (“Adjusted EBITDA”) as net income (loss), plus (i) distributions from equity investments, (ii) non-cash equity-basednon-cash equity-based compensation expense, (iii) interest expense, (iv) income tax expense, (v) depreciation and amortization, (vi) impairments, and (vii) other expense (including lower of cost or market inventory adjustments recorded in cost of product), less (i) gain (loss) on divestiture and other, net, (ii) gain (loss) on early extinguishment of debt, (iii) income from equity investments, (iv) interest income, (v) other income, (vi) income tax benefit, (vi) other income, and (vii) the noncontrolling interestsinterest owners’ proportionate share of revenues and expenses. We believe the presentation of Adjusted EBITDA provides information useful to investors in assessing our financial condition and results of operations and that Adjusted EBITDA is a widely accepted financial indicator of a company’s ability to incur and service debt, fund capital expenditures, and make distributions. Adjusted EBITDA is a supplemental financial measure that management and external users of our consolidated financial statements, such as industry analysts, investors, commercial banks, and rating agencies, use, among other measures, to assess the following:

our operating performance as compared to other publicly traded partnerships in the midstream industry, without regard to financing methods, capital structure, or historical cost basis;

the ability of our assets to generate cash flow to make distributions; and

the viability of acquisitions and capital expenditures and the returns on investment of various investment opportunities.

Adjusted EBITDA increased by $108.1$40.5 million for the three months ended September 30, 2020,2021, primarily due to (i) a $66.0$44.7 million increase in total revenues and other, (ii) a $12.2 million decrease in operation and maintenance expenses, and (iii) a $4.3 million decrease in property taxes. These amounts were offset partially by (i) an $8.2 million decrease in distributions from equity investments, (ii) a $6.1 million increase in general and administrative expenses excluding non-cash equity-based compensation expense, and (iii) a $5.2 million increase in cost of product (net of lower of cost or market inventory adjustments).
Adjusted EBITDA decreased by $80.6 million for the nine months ended September 30, 2021, primarily due to (i) a $96.8 million increase in cost of product (net of lower of cost or market inventory adjustments), (ii) a $44.3 million decrease in operation and maintenance expenses, and (iii) a $13.0 million increase in total revenues and other. These amounts were offset partially by (i) a $9.3$17.2 million increase in general and administrative expenses excluding non-cash equity-basednon-cash equity-based compensation expense, and (ii) a $4.1 million increase in property taxes.
Adjusted EBITDA increased by $274.9 million for the nine months ended September 30, 2020, primarily due to (i) a $181.1 million decrease in cost of product (net of lower of cost or market inventory adjustments), (ii) a $102.1 million increase in total revenues and other, (iii) a $31.2$14.7 million decrease in operation and maintenance expenses, and (iv) a $6.0 million increase in distributions from equity investments. These amounts were offset partially by (i) a $28.6$32.8 million increase in generaltotal revenues and administrative expenses excluding non-cash equity-based compensation expenseother and (ii) an $11.4$11.3 million increasedecrease in property taxes.
The above-described decreasesabove-described variances in cost of product and total revenues and other include the impacts resulting from a change in accounting for the marketing contracts with AESC effective April 1, 2020, which had no net impact on Adjusted EBITDA (see Executive SummarySummary—Commodity purchase and sale agreements within this Item 2).

Free cash flow.We define “Free cash flow” as net cash provided by operating activities less total capital expenditures and contributions to equity investments, plus distributions from equity investments in excess of cumulative earnings. Management considers Free cash flow an appropriate metric for assessing capital discipline, cost efficiency, and balance-sheetbalance-sheet strength. Although Free cash flow is the metric used to assess WES’s ability to make distributions to unitholders, this measure should not be viewed as indicative of the actual amount of cash that is available for distributions or planned for distributions for a given period. Instead, Free cash flow should be considered indicative of the amount of cash that is available for distributions, debt repayments, and other general partnership purposes.
Free cash flow increaseddecreased by $268.5 million and $769.9$59.7 million for the three and nine months ended September 30, 2020, respectively,2021, primarily due to (i) decreasesa decrease of $183.6$60.8 million and $575.0 million, respectively, in capital expenditures, (ii) increases of $52.7 million and $105.2 million, respectively, in net cash provided by operating activities, and (iii) decreasespartially offset by a decrease of $27.8$3.2 million and $89.1 million, respectively, in contributions to equity investments.
Free cash flow increased by $151.3 million for the nine months ended September 30, 2021, primarily due to (i) a decrease of $154.5 million in capital expenditures, (ii) a decrease of $15.3 million in contributions to equity investments, and (iii) an $8.3 million increase in distributions from equity investments in excess of cumulative earnings. These amounts were offset partially by a decrease of $26.9 million in net cash provided by operating activities.

Reconciliation of non-GAAP financial measures. Adjusted gross margin, Adjusted EBITDA, and Free cash flow are not defined in GAAP. The GAAP measure used by us that is most directly comparable to Adjusted gross margin is operating income (loss).gross margin. Net income (loss) and net cash provided by operating activities are the GAAP measures used by us that are most directly comparable to Adjusted EBITDA. The GAAP measure used by us that is most directly comparable to Free cash flow is net cash provided by operating activities. Our non-GAAPnon-GAAP financial measures of Adjusted gross margin, Adjusted EBITDA, and Free cash flow should not be considered as alternatives to the GAAP measures of operating income (loss),gross margin, net income (loss), net cash provided by operating activities, or any other measure of financial performance presented in accordance with GAAP. Adjusted gross margin, Adjusted EBITDA, and Free cash flow have important limitations as analytical tools because they exclude some, but not all, items that affect operating income (loss),gross margin, net income (loss), and net cash provided by operating activities. Adjusted gross margin, Adjusted EBITDA, and Free cash flow should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. Our definitions of Adjusted gross margin, Adjusted EBITDA, and Free cash flow may not be comparable to similarly titled measures of other companies in our industry, thereby diminishing their utility as comparative measures.
Management compensates for the limitations of Adjusted gross margin, Adjusted EBITDA, and Free cash flow as analytical tools by reviewing the comparable GAAP measures, understanding the differences between Adjusted gross margin, Adjusted EBITDA, and Free cash flow compared to (as applicable) operating income (loss),gross margin, net income (loss), and net cash provided by operating activities, and incorporating this knowledge into its decision-makingdecision-making processes. We believe that investors benefit from having access to the same financial measures that our management considers in evaluating our operating results.

LIQUIDITY AND CAPITAL RESOURCES

Our primary cash uses include capital expenditures,quarterly distributions, debt service, customary operating expenses, quarterly distributions, and distributions to our noncontrolling interest owners.capital expenditures. Our sources of liquidity as of September 30, 2020,2021, included cash and cash equivalents, cash flows generated from operations, available borrowing capacity under the RCF, and potential issuances of additional equity or debt securities. We believe that cash flows generated from these sources will be sufficient to satisfy our short-termshort-term working capital requirements and long-term capital-expenditurelong-term capital-expenditure and debt service requirements. The amount of future distributions to unitholders will depend on our results of operations, financial condition, capital requirements, and other factors, and will be determined by the Board of Directors on a quarterly basis. We may rely on external financing sources, including equity and debt issuances, to fund capital expenditures and future acquisitions. However, we also may use operating cash flows to fund capital expenditures or acquisitions, which could result in borrowings under the RCF to pay distributions or to fund other short-termshort-term working capital requirements.
OurUnder our partnership agreement, requires that we distribute all of our available cash (as(beyond proper reserves as defined in our partnership agreement) within 55 days following each quarter’s end. Our cash flow and resulting ability to make cash distributions are completely dependent on our ability to generate cash flow from operations. Generally, our available cash is our cash on hand at the end of a quarter after the payment of our expenses and the establishment of cash reserves and cash on hand resulting from working capital borrowings made after the end of the quarter. The general partner establishes cash reserves to provide for the proper conduct of our business, including (i) reserves to fund future capital expenditures, (ii) to comply with applicable laws, debt instruments, or other agreements, or (iii) to provide funds for unitholder distributions for any one or more of the next four quarters. We have made cash distributions to our unitholders each quarter since our IPOinitial public offering in 2012. The Board of Directors declared a cash distribution to unitholders for the third quarter of 20202021 of $0.31100$0.32300 per unit, or $132.3$134.9 million in the aggregate. The cash distribution is payable on November 13, 2020,12, 2021, to our unitholders of record at the close of business on October 30, 2020. See Outlook within this Item 2.November 1, 2021.
In November 2020, we announced a buyback program of up to $250$250.0 million of our common units through December 31, 2021. The common units may be purchased from time to time in the open market at prevailing market prices or in privately negotiated transactions. The timing and amount of purchases under the program will be determined based on ongoing assessments of capital needs, our financial performance, the market price of the common units, and other factors, including organic growth and acquisition opportunities and general market conditions. The program does not obligate us to purchase any specific dollar amount or number of units and may be suspended or discontinued at any time. During the nine months ended September 30, 2021, we repurchased 5,586,419 common units on the open market for an aggregate purchase price of $104.4 million. We canceled the units immediately upon receipt. As of September 30, 2021, we had an authorized amount of $113.1 million remaining under the Purchase Program.
Management continuously monitors our leverage positionposition and coordinates our capital expenditures and quarterly distributions with expected cash inflows and projected debt service requirements. We will continue to evaluate funding alternatives, including additionaladditional borrowings and the issuance of debt or equity securities, to secure funds as needed or to refinance maturing debt balances with longer-termlonger-term debt issuances. Our ability to generate cash flows is subject to a number of factors, some of which are beyond our control. Read Risk Factors under Part II, Item 1A of this Form 10-Q.

Working capital. As of September 30, 2020, we had a $193.5 million working capital deficit, which we define as the amount by which current liabilities exceed current assets. Working capital is an indication of liquidity and potential needs for short-termshort-term funding. Working capital requirements are driven by changes in accounts receivable and accounts payable and other factors such as credit extended to, and the timing of collections from, our customers, and the level and timing of our spending for acquisitions, maintenance, and other capital activities. As of September 30, 2021, we had a $550.6 million working capital deficit, which we define as the amount by which current liabilities exceed current assets. Our working capital deficit was primarily due to (i) the 5.375%4.000% Senior Notes due 20212022 of $502.1 million and (ii) $220.0 million of outstanding borrowings under the RCF being classified as short-term debt on the consolidated balance sheet as of September 30, 2020.2021. As of September 30, 2020,2021, there was $2.0$1.8 billion available for borrowing under the RCF. See Note 10—Selected Components of Working Capital and Note 11—Debt and Interest Expense in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

Capital expenditures. Our business is capital intensive, requiring significant investment to maintain and improve existing facilities or to develop new midstream infrastructure. Capital expenditures includes maintenance capital expenditures, which include those expenditures required to maintain existing operating capacity and service capability of our assets, such as to replace system components and equipment that have been subject to significant use over time, become obsolete, or reached the end of their useful lives, to remain in compliance with regulatory or legal requirements, or to complete additional well connections to maintain existing system throughput and related cash flows; and expansion capital expenditures, which include expenditures to construct new midstream infrastructure and expenditures incurred to extend the useful lives of our assets, reduce costs, increase revenues, or increase system throughput or capacity from current levels, including well connections that increase existing system throughput.
Capital expenditures in the consolidated statements of cash flows reflect capital expenditures on a cash basis, when payments are made. Capital incurred is presented on an accrual basis. Acquisitions and capitalCapital expenditures as presented in the consolidated statements of cash flows and capital incurred were as follows:

Certain equipment leases were amended during the third quarter of 2021 requiring reassessment of lease classification. As a result, these leases are now classified as operating leases resulting in a reduction of $19.6 million in Net property, plant, and equipment and $20.3 million in Short-term and Long-term debt. The operating leases resulted in additions of $4.8 million in Other assets, $3.1 million in Accrued liabilities, and $2.4 million in Other liabilities, on the consolidated balance sheet.

Credit risk. We bear credit risk through exposure to non-paymentnon-payment or non-performancenon-performance by our counterparties, including Occidental, financial institutions, customers, and other parties. Generally, non-paymentnon-payment or non-performancenon-performance results from a customer’s inability to satisfy payables to us for services rendered, minimum-volume-commitmentminimum-volume-commitment deficiency payments owed, or volumes owed pursuant to gas-imbalancegas-imbalance agreements. We examine and monitor the creditworthiness of customers and may establish credit limits for customers. A substantial portion of our throughput is sourced from producers, including Occidental, that recently received credit-ratingcredit-rating downgrades. We are subject to the risk of non-paymentnon-payment or late payment by producers for gathering, processing, transportation, and disposal fees. We also depend on Occidental to remit payments to us for the value of volumes of residue gas, NGLs, crude oil, and condensate that it markets on our behalf under our Marketing Transition Services Agreement. Additionally, we continue to evaluate counterparty credit risk and, in certain circumstances, are exercising our rights to request adequate assurance.
We expect our exposure to the concentrated risk of non-paymentnon-payment or non-performancenon-performance to continue for as long as our commercial relationships with Occidental generate a significant portion of our revenues. While Occidental is our contracting counterparty, gathering and processing arrangements with affiliates of Occidental on most of our systems include not just Occidental-produced volumes, but also, in some instances, the volumes of other working-interest owners of Occidental who rely on our facilities and infrastructure to bring their volumes to market. We also are party to agreements with Occidental under which Occidental is required to indemnify us for certain environmental claims, losses arising from rights-of-wayrights-of-way claims, failures to obtain required consents or governmental permits, and income taxes with respect to the assets previously acquired from Anadarko. See Note 6—Related-Party Transactions in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.
Our ability to make cash distributions to our unitholders may be adversely impacted if Occidental becomes unable to perform under the terms of gathering, processing, transportation, and disposal agreements; commodity purchase and sale agreements; the contribution agreements; or the December 2019 Agreements (see Executive Summary—December 2019 Agreements within this Item 2).Services Agreement.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

Commodity-price risk. Certain of our processing services are provided under percent-of-proceedspercent-of-proceeds and keep-whole agreements for which Occidental is typically responsible for the marketing of the natural gas, condensate, and NGLs.keep-whole agreements. Under percent-of-proceedspercent-of-proceeds agreements, we receive a specified percentage of the net proceeds from the sale of residue and/or NGLs. Under keep-wholekeep-whole agreements, we keep 100% of the NGLs produced, and the processed natural gas, or value of the natural gas, is returned to the producer, and because some of the gas is used and removed during processing, we compensate the producer for the amount of gas used and removed in processing by supplying additional gas or by paying an agreed-uponagreed-upon value for the gas used.
For the nine months ended September 30, 2020, 93%2021, 92% of our wellhead natural-gasnatural-gas volume (excluding equity investments) and 100% of our crude-oilcrude-oil and produced-waterproduced-water throughput (excluding equity investments) were serviced under fee-basedfee-based contracts. A 10% increase or decrease in commodity prices would not have a material impact on our operating income (loss), financial condition, or cash flows for the next twelve months, excluding the effect of the below-describedbelow-described imbalances.

Item 4.  Controls and Procedures

Evaluation of Disclosure Controls and Procedures. The Chief Executive Officer and Chief Financial Officer of WES’s general partner and WES Operating GP (for purposes of this Item 4, “Management”) performed an evaluation of WES’s and WES Operating’s disclosure controls and procedures as defined in Rules 13a-15(e)13a-15(e) and 15d-15(e)15d-15(e) of the Exchange Act. WES’s and WES Operating’s disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that are filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC, and to ensure that the information required to be disclosed in the reports that are filed or submitted under the Exchange Act is accumulated and communicated to management, including the principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, Management concluded that WES’s and WES Operating’s disclosure controls and procedures were effective as of September 30, 2020.2021.

Changes in Internal Control Over Financial Reporting. Except as described below, thereThere were no changes in WES’s or WES Operating’s internal control over financial reporting during the quarter ended September 30, 2020,2021, that have materially affected, or are reasonably likely to materially affect, WES’s or WES Operating’s internal control over financial reporting.
In October 2020, WES and WES Operating transitioned from Occidental’s Enterprise Resource Planning (“ERP”) system to a stand-alone ERP system. As a result of this implementation, certain processes and internal controls over financial reporting that were provided by Occidental under the Services Agreement have transitioned to WES. Information technology general controls and associated business process controls have been implemented by WES to address the new environment associated with the implementation of this system. There are inherent risks in implementing any new system and Management will continue to evaluate these control changes as part of its assessment of internal control over financial reporting.

PART II.  OTHER INFORMATION

Item 1.  Legal Proceedings

On July 1, 2020, the U.S. Department of Justice, on behalf of the U.S. Environmental Protection Agency (the “EPA”), and the State of Colorado commenced an enforcement action in the United States District Court for the District of Colorado against Kerr-McGeeKerr-McGee Gathering LLC (“KMG”), a wholly owned subsidiary of WES, for alleged non-compliancenon-compliance with the leak detection and repair requirements of the federal Clean Air Act (“LDAR requirements”) at its Fort Lupton facility in the DJ Basin complex. KMG previously had been in negotiations with the EPA and the State of Colorado to resolve the alleged non-compliancenon-compliance at the Fort Lupton facility. Per the complaint, plaintiffs pray for injunctive relief, remedial action, and civil penalties. Management cannot reasonably estimate the outcome of this action at this time.
WGR Operating, LP (“WGR”), another wholly owned subsidiary of WES, finalized negotiations and agreed to a consent decree with the State of Wyoming with respect to alleged non-compliance with LDAR requirements at its Granger, Wyoming facility. The consent decree has been filed with the Wyoming court, and WGR has timely paid a $100,000 fine to the State of Wyoming.
On August 12, 2019, Sanchez Energy Corporation and certain of its affiliated companies (collectively, “Sanchez”) filed a voluntary petition for relief under Chapter 11 of the U.S. Bankruptcy Code in the United States Bankruptcy Court for the Southern District of Texas. While Sanchez holds a working interest in the acreage dedicated to our Springfield system, Sanchez also was the upstream operator for substantially all of the natural gas, crude oil, and NGLs that the Springfield system gathers and that WES processes in the Eagle Ford Shale Play. On April 29, 2020, we received notice that Sanchez filed a motion to reject a number of midstream and downstream agreements with commercial counterparties, including Sanchez’s Springfield gathering agreements and agreements obligating Sanchez to deliver the gas volumes gathered by the Springfield system to our Brasada processing plant. We do not believe the Springfield gatheringobjected to Sanchez’s rejection and related agreements are eligible for rejection as a matter of law, and we have therefore filed both an objection to the proposed rejection, andinstituted an adversary proceeding for a declaratory judgmentregarding such rejection. On May 6, 2021, the Bankruptcy Court issued an opinion determining, among other things, that Sanchez’s Springfield gathering agreements were rejected, but that such agreements may not be rejected.

contain covenants running with the land that survive rejection, thus preserving the acreage dedication to our Springfield system. We intend to continue defending our contractual rights in the bankruptcy proceeding and any other appropriate venue.
On May 15, 2020, Gavilan Resources LLC (“Gavilan”), an entity that owns a 25% working interest in the acreage where the Springfield gathering system and Brasada processing plant are located, also filed for Chapter 11 bankruptcy protection. As a part of this bankruptcy, Mesquite Energy, Inc. (the successor to Sanchez) (“Mesquite”) purchased Gavilan’s assets at auction. Gavilan did not assume and assign its agreements with Springfield as part of its asset sale. Instead, the assets sold to Mesquite remain subject to any covenants, servitudes, or similar agreements that could be equitable servitudes or covenants running with the land, pending a further order of the bankruptcy court. As with
The parties to the Sanchez agreements,and Gavilan proceedings discussed above are currently working toward a comprehensive legal and commercial settlement of the matters in dispute. Nevertheless, we do not believe Gavilan’s agreements may be rejected or left behind and believe they should remain attached to the Gavilan assets.
We cannot make any assurances regarding the ultimate outcome of these negotiations or the Sanchez and Gavilan proceedings themselves, and theirany resulting impact on WES due to the uncertainties associated with the bankruptcyongoing process.

On October 29, 2020, WGR Operating, LP (“WGR”), on behalf of itself and derivatively on behalf of Mont Belvieu JV, filed suit against Enterprise Products Operating, LLC (“Enterprise”) and Mont Belvieu JV (as a nominal defendant) in the District Court of Harris County, Texas. Our lawsuit seeks a declaratory judgment regarding proper revenue allocation as set forth in the Operating Agreement between Mont Belvieu JV (of which WGR is a 25% owner) and Enterprise (the “Operating Agreement”) related to fractionation trains at the Mont Belvieu complex in Chambers County, Texas. Specifically, the Operating Agreement sets forth a revenue allocation structure, whereby revenue would be allocated to the various fracs at the Mont Belvieu complex in sequential order, with Fracs VII and VIII (which are owned by Mont Belvieu JV) following Fracs I through VI, but preceding any “Later Frac Facilities.” Subsequent to the construction of Fracs VII and VIII, Enterprise built Fracs IX, X, and XI, which it wholly owns, and has signaled its intention to treat such subsequent fracs as outside the Mont Belvieu revenue allocation. We do not believe Enterprise’s attempt to bypass the agreed-toagreed-to revenue allocation is proper under the parties’ agreements and now seek judicial determination. We currently sue only for declaratory judgment to avoid potential future damages. We cannot make any assurances regarding the ultimate outcome of this proceeding and its resulting impact on WGR or WES.

Except as discussed above, we are not a party to any legal, regulatory, or administrative proceedings other than proceedings arising in the ordinary course of business. Management believes that there are no such proceedings for which a final disposition could have a material adverse effect on results of operations, cash flows, or financial condition, or for which disclosure is otherwise required by Item 103 of Regulation S-K.S-K.

Item 1A.  Risk Factors

Security holders and potential investors in our securities should carefully consider the risk factors included below and those set forth under Part I, Item 1A in our Form 10-K10-K for the year ended December 31, 2019,2020, together with all of the other information included in this document, and in our other public filings, press releases, and public discussions with management. In addition to the risk factors described below, to the extent the COVID-19 pandemic adversely affects our business and financial results, it also may exacerbate many of the risks described in the “Risk Factors” section of our Annual Report on Form 10-K for the year ended December 31, 2019, such as those relating to our need to generate sufficient cash flows to service our indebtedness.
Additionally, for a full discussion of the risks associated with Occidental’s business, see Item 1A under Part I in Occidental’s Form 10-K10-K for the year ended December 31, 2019,2020, Occidental’s quarterly reports on Form 10-Q10-Q and Occidental’s other public filings, press releases, and public discussions with Occidental management. We have identified the below risk factors as important factors that could cause our actual results to differ materially from those contained in any written or oral forward-lookingforward-looking statements made by us or on our behalf.

Because we are dependent on Occidental as our largest customer and the owner of our general partner, any development that materially and adversely affects Occidental’s operations, financial condition, or market reputation could have a material and adverse impact on us. Material adverse changes at Occidental could restrict our access to capital, make it more expensive to access the capital markets, or increase the costs of our borrowings.
We are dependent on Occidental as our largest customer and the owner of our general partner, and we expect to derive significant revenue from Occidental for the foreseeable future. As a result, any event, whether in our area of operations or otherwise, that adversely affects Occidental’s production, financial condition, leverage, market reputation, liquidity, results of operations, or cash flows may adversely affect our revenues and cash available for distribution. Accordingly, we are indirectly subject to the business risks of Occidental, including, but not limited to, the volatility of oil and natural-gas prices, the availability of capital on favorable terms to fund Occidental’s exploration and development activities, the political and economic uncertainties associated with Occidental’s foreign operations, transportation-capacity constraints, and shareholder activism.
Further, we are subject to the risk of non-payment or non-performance by Occidental, including with respect to our gathering and transportation agreements. For example, we are currently involved in a dispute with Occidental regarding the calculation of the cost-of-service rate under a gathering contract related to our DJ Basin oil system. If such dispute is resolved in a manner adverse to us, such resolution could have a negative impact on our financial condition and results of operations, including a reduction in rates and a non-cash charge to earnings. In addition, we cannot predict the extent to which Occidental’s business would be impacted if conditions in the energy industry were to deteriorate further, nor can we estimate the impact such conditions would have on Occidental’s ability to perform under our gathering and transportation agreements with Occidental. Accordingly, any material non-payment or non-performance by Occidental could reduce our ability to make distributions to our unitholders.
Any material limitations to our ability to access capital as a result of adverse changes at Occidental could limit our ability to obtain future financing on favorable terms, or at all, or could result in increased financing costs in the future. Similarly, material adverse changes at Occidental could adversely impact our unit price, thereby limiting our ability to raise capital through equity issuances or debt financing, or adversely affect our ability to engage in or expand or pursue our business activities, and also prevent us from engaging in certain transactions that might otherwise be considered beneficial to us.
See Occidental’s reports filed under the Securities and Exchange Act of 1934, as amended, with the SEC (which are not, and shall not be deemed to be, incorporated by reference herein), for a full discussion of the risks associated with Occidental’s business.

Furthermore, the implementation of procedures and controls to monitor and mitigate heightened security threats to our facilities, infrastructure, and information during this time may result in increased costs, and there can be no assurance that such additional controls and procedures will be effective to prevent security breaches. For these reasons, limited working arrangements and other related restrictions may impact our operations and management effectiveness and may introduce,treated as partnerships for U.S. federal income tax purposes or increase the likelihoodamount of material riskstaxes payable by unitholders in publicly traded partnerships. You are urged to consult with your own tax advisor with respect to the status of regulatory or administrative developments and proposals and their potential effect on your investment in our business, operations, productivity, and results of operations.
The COVID-19 pandemic and resulting mitigation measures also are having an adverse impact on global economic conditions, and as discussed below, are contributing to a significant decline in demand for oil, NGLs, and natural gas, resulting in lower commodity prices that will negatively impact our and our customers’ financial outlooks and activity levels.common units.

The combined effectsOur profitability may be negatively impacted by inflation in the cost ofoutput decisions by the Organization of the Petroleum Exporting Countries (“OPEC”) labor, materials, and efforts to fight the global outbreak of COVID-19 have caused significant declines in oil prices, which will negatively impact our operations, earnings, cash flows, and ability to make cash distributions to our unitholders.services.

In March 2020, OPEC announced its intentionAlthough inflation in the United States has been relatively low in recent years, the U.S. economy could experience a significant inflationary effect from, among other things, supply chain disruptions caused by, or governmental stimulus or fiscal policies adopted in response to, increase the supplyCOVID-19 crisis. While we cannot predict any future trends in the rate of oil that its member countries make available for sale on the international market. The resulting expectation of increased supply caused commodity prices to fall significantly. At the same time, efforts to fightinflation, the global outbreak of COVID-19 have caused a pronounced reductionpandemic has brought unprecedented uncertainty to the domesticnear-term economic outlook. A significant increase in inflation would raise our costs for labor, materials and international demand for oil as business closures, manufacturing restrictions,services, and prolonged limitations on other commercial activity and travel persist. Even after this global pandemic abates and government-imposed restrictions on activities are relaxed, public-health concerns may give rise to significant long-term shifts in consumer behavior that may impede hydrocarbon-demand recovery. The combination of expected additional supply and significantly reduced demand has caused NYMEX West Texas Intermediate crude-oil daily settlement prices to fall to below $20.00 per barrel in April 2020. We are uncertain as to the extent and duration of the currently strained macroeconomic market conditions, and the oversupply and low demand for oil may continue for an extended period of time, potentially impacting our and our customers’ businesses as follows:

The impact of downstream-storage constraints and potential production curtailments reducing revenues generated from our midstream gathering and processing contracts. With significant excess supply, domestic oil-storage capacity could reach operational limits. As available storage nears capacity, our customers may shut-in field production due to limited downstream-takeaway alternatives or resulting wellhead economics. If production is shut-in for these or for other reasons, affected producers may become insolvent or seek to avoid their contractual obligations with us, in which case, our earnings, cash flows from operations, and ability to make cash distributions to our unitholders could be materially and adversely impacted. Additionally, a significant decline in produced volumes on our systems may trigger liability under certain downstream transportation commitments we have through December 31, 2020.

Exposure to the credit risk of our customers, including Occidental, and any material non-payment or non-performance by these parties.To the extent any of our customers, including Occidental, is in financial distress, we are exposed to risk of non-payment for our services or for other amounts owed to us. Also, if any of our customers enter bankruptcy proceedings, then those customers may seek to renegotiate contracts with us at lower rates or altogether reject contracts. For example, on April 29, 2020, we received notice that Sanchez has elected to reject a number of midstream and downstream agreements with commercial counterparties, including Sanchez’s Springfield gathering agreements and agreements obligating Sanchez to deliver the gas volumes gathered by the Springfield system to our Brasada processing plant. As a result of such contract breaches or bankruptcy events our Eagleford assets could be impaired and our earnings, cash flows from operations, and ability to make cash distributions to our unitholders could be materially and adversely impacted.

Credit-rating downgrades negatively impact our cost of and ability to access capital.Our costs of borrowing and ability to access the capital markets are affected by, among other factors, market conditions and the credit ratings assigned to WES Operating’s debt by the major credit rating agencies. In March, May, and June 2020, WES Operating’s credit ratings were downgraded below investment grade by Fitch, S&P, and Moody’s. As a result of these downgrades, financing costs under WES Operating’s RCF increased. Additionally, WES Operating currently has $3.5 billion of outstanding senior notes that provide for increased interest rates following downgrade events. For example, the March, May, and June downgrades to WES Operating’s credit ratings resulted in a $34.6 million increase to WES Operating’s annualized borrowing costs attributable to the aforementioned senior notes. Additional downgrades to WES Operating’s credit ratings will further increase its borrowing costs, and could adversely affect WES Operating’s ability to issue public debt and effectively execute aspects of our business strategy.
Credit-rating downgrades also could trigger obligations to provide financial assurance of our performance under certain contractual arrangements. At September 30, 2020, there were $5.0 million in letters of credit or cash-provided assurance of our performance outstanding under contractual arrangements with credit-risk-related contingent features.

Restrictions in the RCF may limit our ability to access capital.The financial restrictions in our RCF could restrict our ability to access capital. The RCF contains various customary covenants, certain events of default, and a maximum consolidated leverage ratio as of the end of each fiscal quarter (which is defined as the ratio of consolidated indebtedness as of the last day of a fiscal quarter to Consolidated EBITDA, as defined in the RCF, for the most-recent four-consecutive fiscal quarters ending on such day) of 5.0 to 1.0. If we experience an extended period of diminished earnings, we may be unable to draw on our RCF, be required to repay existing RCF borrowings, or be required to seek waivers or amendments to our RCF to comply with our leverage-ratio requirements. Any future waivers or amendments also may trigger additional pricing increases for available credit. If we are unable to access credit to fundrecover higher costs through our business requirements, or the cost of available credit increases,commercial agreements, would negatively impact our earnings,profitability and cash flows from operations, and abilityavailable for distribution to make cash distributions to our unitholders could be materially and adversely impacted.unitholders.

For example, during the nine months ended September 30, 2020, we recognized long-lived asset and other impairments of $200.6 million (seecommon units through December 31, 2021. See Note 8—Property, Plant,5—Equity and EquipmentPartners’ Capital in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q). Further, during the first quarter of 2020, we performed an interim goodwill impairment test that resulted in us recognizing a $441.0 million goodwill impairment for our gathering and processing reporting unit. Prolonged low commodity prices, further commodity-price declines, and changes to producers’ drilling plans in response to lower prices could result in additional long-lived asset impairments in the future. Future non-cash asset impairments could negatively affect our results of operations.

The reduction to our quarterly per-unit distribution and expenditure plans may not prove adequate to offset the potential impacts of COVID-19 and the recent decline in commodity prices to our operations, performance and liquidity, and may impede our long-term growth objectives.

On April 20, 2020, we announced a cash distribution of $0.31100 per unit for the first quarter of 2020, which represents a 50% reduction to the prior-quarter distribution, and reductions to estimated 2020 capital and operating expenditures. Our second-quarter and announced third-quarter distributions have remained at $0.31100 per unit. On August 10, 2020, we also announced a further downward revision to our estimated full-year 2020 capital expenditures. These cash-preservation measures are intended to enhance our financial strength for the duration of the COVID-19 macroeconomic disruption and the weakened commodity-price environment; however, the duration and severity of this pandemic and concomitant economic downturn remains uncertain. There can be no assurance that these announced actions will be adequate to preserve our financial health for the required duration and additional actions, including additional per-unit distribution reductions, may be necessary to manage through the current environment. Furthermore, any cash we preserve from delaying or abandoning capital projects will necessarily delay or eliminate future returns we hoped to generate from previously planned projects, which may meaningfully impact our ability to generate long-term revenue and cash-flow growth. Also, our decision to preserve cash by reducing our quarterly distribution to common unitholders may diminish the long-term value of our units and limit our ability, or increase the cost of, accessing future equity capital necessary to fund our business or to preserve our balance sheet.
