Reserve engineering is a process of estimating underground accumulations of natural gas, oil and NGLs that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and our development program. Accordingly, reserve estimates may differ significantly from the quantities of natural gas, oil and NGLs that are ultimately recovered.
All forward-looking statements attributable to us are expressly qualified in their entirety by this cautionary statement.

Table of Contents
Index to Financial Statements
Standardized measure” Discounted future net cash flows estimated by applying year-end prices to the estimated future production of year-end proved reserves. Future cash inflows are reduced by estimated future production and development costs based on period-end costs to determine pre-tax cash inflows. Future income taxes, if applicable, are computed by applying the statutory tax rate to the excess of pre-tax cash inflows over our tax basis in the natural gas and oil properties.

Unconventional play”  A play in which the targeted reservoirs generally fall into one of three categories: tight sands, coal beds, or shales. The reservoirs tend to cover large areas and lack the readily apparent traps, seals and discrete hydrocarbon-water boundaries that typically define conventional reservoirs. These reservoirs generally require fracture stimulation treatments or other special recovery processes in order to produce economic flow rates.
Undeveloped acreage”  Those leased acres on which wells have not been drilled or completed to a point that would permit the production of economic quantities of oil or gas regardless of whether such acreage contains proved reserves. For additional information, see the SEC’s definition in Item 1208(c)(4) of Regulation S-K, a link for which is available at the SEC’s website.
Undeveloped natural gas, oil and NGL reserves”  Undeveloped natural gas, oil and NGL reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.  Also referred to as “undeveloped reserves.”  For additional information, see the SEC’s definition in Rule 4-10(a) (31) of Regulation S-X, a link for which is available at the SEC’s website.
Undeveloped reserves”  See “undeveloped natural gas, oil and NGL reserves.”
Wells to sales”  Wells that have been placed on sales for the first time.
Working interest”  An operating interest that gives the owner the right to drill, produce and conduct operating activities on the property and to receive a share of production.
Workovers”  Operations on a producing well to restore or increase production.
WTI”  West Texas Intermediate, the benchmark oil price in the United States.
SUMMARY RISK FACTORS
Risks Related to Our Business
Natural gas, oil and NGL prices and basis differentials greatly affect our revenues and thus profits, liquidity, growth, ability to repay our debt and the value of our assets.
Significant capital investment is required to develop and replace our reserves and conduct our business.
If we are not able to develop and replace reserves, our production levels and thus our revenues and profits may decline.
Our business depends on access to natural gas, oil and NGL gathering, processing and transportation systems and facilities. Changes to access and cost of these systems and facilities could adversely impact our business and financial condition. Our commitments to assure availability of transportation could lead to substantial payments for capacity we do not use if production falls below projected levels.
Strategic determinations, including the allocation of capital and other resources to strategic opportunities, are challenging in the face of shifting market conditions, and our failure to appropriately allocate capital and resources among our strategic opportunities may adversely affect our financial condition and reduce our future growth rate.
Certain of our undeveloped assets are subject to leases that will expire over the next several years unless production is established on units containing the acreage.
Our proved natural gas, oil and NGL reserves are estimates that include uncertainties. Any material changes to these uncertainties or underlying assumptions could cause the quantities and net present value of our reserves to be overstated or understated.
Natural gas and oil drilling and producing and transportation operations are complex and can be hazardous and may expose us to liabilities. Incidents related to HSE performance and our asset and operating integrity could adversely impact our business and financial condition.
We have made significant investments in oilfield service businesses, including our drilling rigs, water infrastructure and pressure pumping equipment, to lower costs and secure inputs for our operations and transportation for our production. If our development and production activities are curtailed or disrupted, we may not recover our investment in these activities, which

could adversely impact our results of operations. In addition, our continued expansion of these operations may adversely impact our relationships with third-party providers.
Our business depends on the availability of water and the ability to dispose of water. Limitations or restrictions on our ability to obtain or dispose of water may have an adverse effect on our financial condition, results of operations and cash flows.
A large portion of our producing properties remain concentrated in the Appalachian basin, making us vulnerable to risks associated with operating in limited geographic areas.
Many of our business operations depend on activities performed by third parties. Changes to availability, costs and performance of personnel, products and services provided by third parties could adversely impact our business and financial condition.
Changes to the ability of our customers to receive our products or meet their financial, performance and other obligations to us could adversely impact our business and financial condition.
Competition in the oil and natural gas industry is intense, making it more difficult for us to market natural gas, oil and NGLs, to secure trained personnel and appropriate services, to obtain additional properties and to raise capital.
We may be unable to dispose of assets on attractive terms, and may be required to retain liabilities for certain matters.
Changes to applicable U.S. tax laws and regulations could affect our business and future profitability.
Our ability to use our net operating loss carryforwards and certain other tax attributes will be limited.
We may experience adverse or unforeseen tax consequences due to further developments affecting our deferred tax assets which could significantly affect our results of operations.
A cyber incident could result in information theft, data corruption, operational disruption and/or financial loss.
Terrorist activities could materially and adversely affect our business and results of operations.
The physical impacts of adverse weather may have a negative impact on our business and results of operations.
Negative public perception regarding us and/or our industry and increasing attention to ESG matters could have an adverse effect on our business, financial condition and results of operations and damage our reputation.
Judicial decisions can affect our rights and obligations.
Common stockholders will be diluted if additional shares are issued.
Anti-takeover provisions in our organizational documents and under Delaware law may impede or discourage a takeover, which could cause the market price of our common stock to decline.
Loss of our key executive officers or other personnel, or an inability to attract and retain such officers and personnel, could negatively affect our business.
The COVID-19 pandemic has negatively affected, and may in the future negatively affect, our business, operating results and financial condition.
Risks Related to our Indebtedness and Financing Abilities
A downgrade in our credit rating could negatively impact our cost of and ability to access capital and our liquidity.
Our current and future levels of indebtedness may adversely affect our results and limit our growth.
Any significant reduction in the borrowing base under our 2018 credit facility may negatively impact our ability to fund our operations, and we may not have sufficient funds to repay borrowings under our 2018 credit facility if required as a result of a borrowing base redetermination.
Our ability to comply with the covenants and other restrictions in our financing agreements may be affected by events beyond our control, including prevailing economic and financial conditions.
The elimination of LIBOR may adversely affect the cost of our borrowings.
Risks Related to Governmental Regulation
Climate change legislation or regulations governing the emissions of greenhouse gases could result in increased operating costs and reduce demand for the natural gas, oil and NGLs we produce, and concern in financial and investment markets over greenhouse gasses and fossil fuel production could adversely affect our access to capital and the price of our common stock.
We, our service providers and our customers are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities.

PART I
ITEM 1. BUSINESS
Southwestern Energy Company (including its subsidiaries, collectively, “we”, “our”, “us”, “the Company” or “Southwestern”) is an independent energy company engaged in exploration, development and production activities, including the related marketing of natural gas, oil andassociated natural gas liquids (“NGLs”) and oil produced in our operations.  Southwestern is a holding company whose assets consist of direct and indirect ownership interests in, and whose business is conducted substantially through, its subsidiaries.  Currently we operate exclusively in the United States.  Our common stock is listed and traded on the NYSE under the ticker symbol “SWN.”
Southwestern, which is incorporated in Delaware, has its executive offices located at 10000 Energy Drive, Spring, Texas 77389, and can be reached by phone at 832-796-1000.  The Company also maintains offices in Tunkhannock, Pennsylvania and Morgantown, West Virginia. 
Our Business Strategy
We aim to deliver sustainableeconomic returns and industry-leading returnsoptimize our ability to generate free cash flow through excellenceresponsible natural gas development. As we develop our core positions in explorationthe Appalachian and Haynesville natural gas basins in the U.S., we will concentrate on:
Creating Value. We seek to create value for our stakeholders by allocating capital that is focused on earning economic returns; delivering free cash flow; upgrading the quality, depth and capital efficiency of our drilling inventory; and converting resources to proved reserves.
Financial Strength. We intend to protect our financial strength by lowering our leverage ratio and total debt; extending the weighted average years to maturity of our debt; lowering our cost of debt; deploying hedges to protect against downward price movement; covering our costs and meeting other financial commitments; and maintaining a strong liquidity position.
Focus on Execution. We are focused on operating effectively and efficiently with HSE and ESG as core values; building on our data analytics, operating execution, strategic sourcing, vertical integration and large-scale asset development expertise; further enhancing well performance, optimizing well costs and reducing base production declines; growing margins and securing flow assurance through commercial and marketing performance from our extensive resource basearrangements.
Capturing the Tangible Benefits of Scale. We strive to create a competitive advantage through strategic transactions that we believe will enhance enterprise returns and targeted expansiondeliver financial synergies and operational economies. We believe these transactions lower the risk of our activitiesbusiness, expand our opportunity set, increase business optionality and assets along the hydrocarbon value chain.  build upon our demonstrated record of asset integration.
Our Company’s formula embodies our corporate philosophy and guides how we operate our business:
swn-20191231_g2.jpg
Our formula, “The Right People doing the Right Things, wisely investing the cash flow from our underlying Assets will create Value+,” also guides how we conduct our business strategy.  business:
swn-20211231_g2.jpg
We always strive to attract and retain strong talent, to work safely, andto act ethically with unwaveringsteadfast vigilance for the environment and the communities in which we live and operate, and to creatively apply technical skills which weto grow and develop our asset base. We believe these practices will growenhance long-term value for our shareholders.  The arrow in our formula is not a straight line: we acknowledge that factors may adversely affect quarter-by-quarter results, but the path over time points to value creation.
In applying these core principles, we concentrate on:
Financial Strength. We are committed to rigorously managing our balance sheet and financial risks.  We budget to invest from our net cash flow from operations, supplemented during 2019 and 2020 by a portion of the proceeds from the 2018 Fayetteville Shale sale (described below).  Additionally, we protect our projected cash flows through hedging and continue to maintain a strong balance sheet with ample liquidity. 
Increasing Margins. We apply strong technical, operational, commercial and marketing skills to reduce costs, improve the productivity of our wells and pursue commercial arrangements to extract greater value.  We believe our demonstrated ability to improve margins, especially by leveraging the scale of our large assets, gives us a competitive advantage as we move into the future.
Exercising Capital Allocation Discipline. We continually assess market conditions in order to adjust our capital allocation decisions to maximize shareholder returns.  This allocation process includes consideration of multiple alternatives including but not limited to the development of our natural gas and oil assets, strategic acquisitions, reducing debt and returning capital to our shareholders.
Operational Value Creation.  We prepare an economic analysis for our drilling programs and other investments based upon the expected net present value added for each dollar to be invested, which we refer to as Present Value Index, or PVI.  We target projects that generate the highest returns in excess of our cost of capital.  This disciplined investment approach governs our investment decisions at all times, including the current lower-price commodity market.
Dynamic Management of Assets Throughout Life Cycle.  We own large-scale, long-life assets in various phases of development.  In early stages, we ramp up development through technical, operational and commercial skills, and as they grow we look for ways to maximize their value through efficient operating practices along with applying our commercial and marketing expertise.
Deepening Our Inventory.  We continue to expand the inventory of properties that we can develop profitably by converting our extensive resources into proved reserves, targeting additions whose productivity largely has been demonstrated and improving efficiencies in production.

Technological Innovation.  Our people constantly search forExpanding our operations into the next revolutionary technologyHaynesville with the Indigo Merger and other operational advancements to capture greater value in unconventional hydrocarbon resource development.  These developments – whether single, step-changing technologies or a combination of several incremental ones – can reduce findingGEPH Merger. This expansion lowered our enterprise business risk, deepened our economic drilling inventory, expanded our business opportunity set and development costsoptionality and thus increase our margins.
Environmental Solutions and Policy Formation. We are a leader in identifying and implementing innovative solutions to unconventional hydrocarbon development to minimize the environmental and community impacts of our activities.  We work extensively with governmental, non-governmental and industry stakeholders to develop responsible and cost-effective programs.  We demonstrate that a company can operate responsibly and profitably, putting us in a better position to comply with new regulations as they evolve.

(1)Pre-tax PV-10 is a non-GAAP financial measure. We believe that the presentation of pre-tax PV-10 is relevant and useful to our investors as supplemental disclosure to the standardized measure of discounted future cash flows (“standardized measure”), or after-tax PV-10 amount, because it presents the discounted future net cash flows attributable to our proved reserves prior to taking into account future corporate income taxes and our current tax structure. While the standardized measure is dependent on the unique tax situation of each company, pre-tax PV-10 is based on a pricing methodology and discount factors that are consistent for all companies. Because of this, pre-tax PV-10 can be used within the industry and by creditors and securities analysts to evaluate estimated net cash flows from proved reserves on a more comparable basis. The difference between the standardized measure and the pre-tax PV-10 amount is the discounted amount of estimated future income taxes. See “TableSupplemental Oil and Gas Disclosures (Unaudited)” to the consolidated financial statements of Contentsthis Annual Report for more information about the calculation of standardized measure.
Index(2)Our existing tax attributes, including net operating losses and remaining depreciable tax basis related to Financial Statementsour natural gas and oil properties, more than offset our future net operating income, resulting in no tax effect to our PV-10 calculation for the year ended December 31, 2020.
Our year-end 2021 reserve estimates totaled 21.1 Tcfe with an after-tax PV-10 of $18.7 billion. Our reserve estimates and the after-tax PV-10 measure, or standardized measure, of discounted future net cash flows relating to proved natural gas, oil and NGL reserve quantities, are highly dependent upon the respective commodity price used in our reserve and after-tax PV-10 calculations.
Our reserves increased 7%76% in 2019,2021, compared to 2018, primarily through extensions, discoveries and other additions, along with positive performance revisions.
The decrease in our reserves in 2018, compared to 2017, was2020, primarily due to the Fayetteville Shale sale. Excluding the impact of the Fayetteville Shale sale, our reserves increased 7%acquired from Indigo and GEPH as well as an increase in 2018, compared to 2017, primarily through extensions, discoveries and other additions, along with increases in both price and performance revisions in Appalachia. commodity pricing.
Our after-tax PV-10 value decreasedincreased in 20192021 compared to 20182020 primarily due to an increase in the SEC 12-month backward-looking commodity prices as well as higher reserve levels and lower future development and production costs were more than offset by lower commodity prices.resulting from the recent acquisitions.
We are the designated operator of approximately 99%98% of our reserves, based on the pre-tax PV-10 value of our proved developed producing reserves, and our reserve life index was approximately 16.412.6 years at year-end 2019.2021, using an estimate of full year production from our recently acquired Indigo and GEPH properties.

The difference in after-tax PV-10, or standardized measure, and pre-tax PV-10 (a non-GAAP measure which is reconciled in the 20192021 Proved Reserves by Category and Summary Operating Data table below) is the discounted value of future income taxes on the estimated cash flows.
We believe that the pre-tax PV-10 value of the estimated cash flows related to our estimated proved reserves is a useful supplemental disclosure to the after-tax PV-10 value.  Pre-tax PV-10 is based on prices, costs and discount factors that are comparable from company to company, while the after-tax PV-10 is dependent on the unique tax situation of each individual company.  We understand that securities analysts use pre-tax PV-10 as one measure of the value of a company’s current proved reserves and to compare relative values among peer companies without regard to income taxes.  We refer you to “Supplemental Oil and Gas Disclosures” in Item 8 of Part II of this Annual Report for a discussion of our standardized measure of discounted future cash flows related to our proved natural gas, oil and NGL reserves, to the risk factor “Our proved natural gas, oil and NGL reserves are estimates that include uncertainties.  Any material changechanges to these uncertainties or underlying assumptions could cause the quantities and net present value of our reserves to be overstated or understated” in Item 1A of Part I of this Annual Report, and to “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Cautionary Statement about Forward-Looking Statements”Statements in Item 7 of Part II of this Annual Report for a discussion of the risks inherent in utilization of standardized measuresmeasure and estimated reserve data.
Lower natural gas, oil and NGL prices can reduce the value of our assets, both by a direct reduction in what the production could be sold for and by making some properties uneconomic, resulting in decreases to the overall value of our reserves and potential non-cash impairment charges to earnings.  Given the fall in commodity prices in 2019 and early 2020 and assuming that commodity prices remain at January 2020 levels for the rest of the first quarter of 2020, we expect a non-cash impairment to our natural gas and oil properties in the first quarter of 2020 ranging from approximately $400 million to $600 million, net of tax. Further non-cash impairments in future periods could occur if the trailing 12-month commodity prices decrease as compared to the average used in prior periods.

(1)The Fayetteville Shale E&P assets and associated reserves were sold in December 2018.
(2)The 2017 proved undeveloped, or PUD, additions of 6,829 Bcfe were comprised of 3,910 Bcfe attributable to adding new undeveloped locations throughout the year through our successful drilling program and 2,919 Bcfe attributable to adding undeveloped locations associated with increased commodity pricing across our portfolio.
(3)Primarily due to changes associated with the analysis of updated data collected in the year and decreases related to current year production.
(4)Consists of reserves associated with planned wells that were PUD at the beginning of the year but were subsequently reclassified to unproved due to changes in the drilling plan, in accordance with the SEC five-year rule.year.
Performance, production and price revisions consist of revisions to reserves associated with wells having proved reserves in existence as of the beginning of the year.  Extensions, discoveries and other additions include new reserves locations added in the current year. Certain planned wells that were proved undeveloped as of the beginning of the year have been rescheduled beyond five years. Accordingly, the proved undeveloped reserves associated with these planned wells have been removed as they now fall outside of the SEC mandated five-year development window. We expect these previous proved undeveloped reserves to be added back in future years.
As of December 31, 2019,2021, we had 6,3009,813 Bcfe of proved undeveloped reserves, all of which we expect will be developed within five years of the initial disclosure as the starting reference date.  During 2019,2021, we invested $638$388 million in connection with converting 1,2351,153 Bcfe, or 19%30%, of our proved undeveloped reserves as of December 31, 20182020 into proved developed reserves and added 1,0043,511 Bcfe of proved undeveloped reserves. Additionally, we added 3,692 Bcfe of proved undeveloped reserves through the Indigo Merger and GEPH Merger. These additions were partially offset by a 24 Bcfe net decrease due to price, performance and production revisions.
As of December 31, 2020, we had 3,787 Bcfe of proved undeveloped reserves.  During 2020, we invested $674 million in connection with converting 1,487 Bcfe, or 24%, of our proved undeveloped reserves as of December 31, 2019 into proved developed reserves and added 474 Bcfe of proved undeveloped reserves. As a result of the commodity price environment in 2019,2020, we had downward price revisions of 4073,288 Bcfe. In addition, we also had 109 Bcfe that was reclassified to unproven. These reductions were more thanpartially offset by a 683567 Bcfe increase due to performance and production revisions.
As of December 31, 2018, we had 6,364 Bcfe ofOur proved undeveloped reserves.  During 2018, we invested $491 million in connection with converting 1,096 Bcfe, or 16%, of our proved undeveloped reserves as of December 31, 2017 into proved developed reserves and added 832 Bcfe of proved undeveloped reserve additions in Appalachia.  Proved undeveloped reserves also decreased in 2018 primarily due to the sale of the Fayetteville Shale E&P assets.

As of December 31, 2017, we had 6,855 Bcfe of proved undeveloped reserves.  During 2017, we invested $23 million in connection with converting 46 Bcfe, or 60%, of our2021 included no proved undeveloped reserves as of December 31, 2016 into proved developed reserves and added 6,829 Bcfe of proved undeveloped reserve additions in Appalachia.  The significant increase in our proved undeveloped reserve additions in 2017 was the result of adding new undeveloped locations throughout the year through our successful drilling program, improved operational performance and increased commodity pricing across our portfolio. 
Our December 31, 2019 proved reserves included 929 Bcfe of proved undeveloped reserves from 90 locations that havehad a positive present value on an undiscounted basis in compliance with proved reserve requirements but dodid not have a positive present value when discounted at 10%. These properties have a negative present value of $50 million when discounted at 10%. We have made a final investment decision and are committed to developing these reserves within five years from the date of initial booking.
We expect that the development costs for our proved undeveloped reserves of 6,3009,813 Bcfe as of December 31, 20192021 will require us to invest an additional $3.0$5.6 billion for those reserves to be brought to production.  Our ability to make the necessary investments to generate these cash inflows is subject to factors that may be beyond our control.  The current commodity price environment has resulted, and could continue to result, in certain reserves no longer being economic to produce, leading to both lower proved reserves and cash flows.  We refer you to the risk factors “Natural gas, oil and NGL prices greatly affect our revenues and thus profits, liquidity, growth, ability to repay our debt and the value of our assets” and “Significant capital investment is required to replace our reserves and conduct our business” in Item 1A of Part I of this Annual Report and to “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Cautionary Statement about Forward-Looking Statements”Statements in Item 7 of Part II of this Annual Report for a more detailed discussion of these factors and other risks.
Preparation of Reserve Estimates
Our proved reserve estimates as of December 31, 2019, 2020 and 2021 included in this Annual Report were prepared by our internal reservoir engineers under the supervision of our management, in accordance with petroleum engineering and evaluation standards published by the Society of Petroleum Evaluation Engineers and definitions and guidelines established by the SEC. These proved reserve estimates have been audited by our independent engineers, Netherland, Sewell & Associates, Inc. (“NSAI”).

Reserve estimates are prepared for each of our properties annually by the reservoir engineers assigned to the asset management team for that property. The reservoir engineering and financial data included in these estimates are reviewed by senior engineers, who are not part of the asset management teams, and by our Director of Reserves, who is the technical person primarily responsible for overseeing the preparation of our reserves estimates. Our Director of Reserves has more than 27 years of experience in petroleum engineering, including the estimation of natural gas and oil reserves, and holds a Bachelor of Science in Petroleum Engineering. Prior to joining us in 2018, our Director of Reserves served in various reservoir engineering roles for EP Energy Company, El Paso Corporation, Cabot Oil & Gas Corporation, Schlumberger and H.J. Gruy & Associates, and is a member of the Society of Petroleum Engineers. He reports to our Executive Vice President and Chief Operating Officer, who has more than 33 years of experience in petroleum engineering including the estimation of natural gas, oil and NGL reserves in multiple basins in the United States, and holds a Bachelor of Science in Petroleum Engineering. Prior to joining Southwestern in 2017, our Chief Operating Officer served in various engineering and leadership roles for EP Energy Corporation, El Paso Corporation, ARCO Oil and Gas Company, Burlington Resources and Peoples Energy Production, and is a member of the Society of Petroleum Engineers.
We engage NSAI, a worldwide leader of petroleum property analysis for industry and financial organizations and government agencies, to independently audit our proved reserves estimates as discussed in more detail below. NSAI was founded in 1961 and performs consulting petroleum engineering services under Texas Board of Professional Engineers Registration No. F-002699. Within NSAI, the two technical persons primarily responsible for auditing our proved reserves estimates (1) have over 24 years and over 20 years of practical experience in petroleum geosciences and petroleum engineering, respectively; (2) have over 13 years and over 20 years of experience in the estimation and evaluation of reserves, respectively; (3) each has a college degree; (4) each is a Licensed Professional Geoscientist in the State of Texas or a Licensed Professional Engineer in the State of Texas; (5) each meets or exceeds the education, training, and experience requirements set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers; and (6) each is proficient in judiciously applying industry standard practices to engineering and geoscience evaluations as well as applying SEC and other industry reserves definitions and guidelines. The financial data included in the reserve estimates is also separately reviewed by our accounting staff. Our proved reserves estimates, as internally reviewed and audited by NSAI, are submitted for review and approval to our President and Chief Executive Officer. Finally, upon his approval, NSAI reports the results of its reserve audit to the Board of Directors, with whom final authority over the estimates of our proved reserves rests. A copy of NSAI’s report has been filed as Exhibit 99.1 to this Annual Report.

Our Reserve Replacement
The reserve replacement ratio measures the success of an E&P company in adding new reserves to replace the reserves that are being depleted by its current production volumes.  TheWe believe the reserve replacement ratio which we discuss below, is an important analytical measure used by investors and peers in the E&P industry to evaluate performance results and long-term prospects.  There areReserve replacement represents the net change in reserves, net of production, divided by our current year production, as shown in our supplemental reserve table disclosures. The reserve replacement ratio is a statistical indicator that has limitations, as toincluding its predictive and comparative value. As an annual measure, the usefulnessreserve replacement ratio can be limited because it may vary widely based on the extent and timing of this measure, as itnew discoveries and the varying effects of changes in prices and well performance. In addition, because the reserve replacement ratio does not reflectconsider the cost or timing of future production of new reserves or the type of reserves, orsuch measure may not be an adequate measure of value creation.

Our Operations
Northeast Appalachia
Northeast Appalachia represented 59%89% of our total 20192021 net production and 38%73% of our total reserves as of December 31, 2019.2021.  Given that we began operating in the Haynesville in the latter part of 2021 as a result of the Indigo Merger and the GEPH Merger, we expect the percentage of production represented by our operations in Appalachia to decrease in 2022. In 2019,2021, our production increased by 228 Bcfe. Our reserves in Northeast Appalachia increased by 4713,538 Bcf, which includedas net additions of 862 Bcf3,962 Bcfe, net upward price revisions of 415 Bcfe and net upward performance revisions of 127 Bcf,270 Bcfe were only partially offset by net downward price revisions of 57 Bcf, disposition of reserves in place of 2 Bcf and production of 459 Bcf.1,108 Bcfe.  As of December 31, 2019,2021, we had approximately 173,994768,050 net acres in Northeast Appalachia and had spud or acquired 727 operateda total of 1,527 wells 641 of which were on production.production that we operated.  Below is a summary of Northeast Appalachia’s operating results for the latest threetwo years:

Our continued ability to bring our Southwest AppalachiaHaynesville production to market will depend on a number of factors including the construction of and/or the availability of capacity on gathering systems and pipelines that we do not own.  We refer you to “Marketing” within Item 1 of Part I of this Annual Report for a discussion of our gathering and transportation arrangements for Southwest AppalachiaHaynesville production.
Fayetteville Shale
On August 30, 2018, we entered into an agreement to effect the Fayetteville Shale sale for $1,865 million, subject to customary adjustments.  In early December 2018, we completed the Fayetteville Shale sale, resulting in net proceeds of $1,650 million, following adjustments due primarily to the net cash flows from the economic effective date of July 1, 2018, to the closing date.
Production in the Fayetteville Shale totaled 243 Bcf for the year ended December 31, 2018, which represented 26% of our total 2018 net production.  In 2018, we invested $33 million in the Fayetteville Shale.
Other
Excluding 2,518,519 acres in New Brunswick, Canada, which have been subject to a government-imposed drilling moratorium since 2015, we held 27,334650 net undeveloped acres for the potential development of new resources as of December 31, 20192021 in areas outside of Appalachia.Appalachia and Haynesville.  This compares to 153,1599,764 net undeveloped acres held at year-end 20182020 in areas outside of Appalachia and 369,236 net undeveloped acres held at year-end 2017,Haynesville, excluding the New Brunswick acreage.
We limited our activities in areas beyond our assets in Appalachia during 2019, 2018 and 2017 as a result of the commodity price environment as we focused our capital allocation on these more economically competitive plays.  There can be no assurance that any prospects outside of our development plays will result in viable projects or that we will not abandon our initial investments. 
New Brunswick, Canada. We currently hold exclusive licenses to search and conduct an exploration program covering 2,518,519 net acres in New Brunswick.  In 2015, the provincial government in New Brunswick imposed a moratorium on hydraulic fracturing until it is satisfied with a list of conditions.  In response to this moratorium, the Company requested and waswe were granted an extension of itsthe licenses to March 2021.  In May 2016, the provincial government announced that the moratorium would continue indefinitely.  Given this development, we fully impaired our investment in New Brunswick in 2016. In 2021, we were granted a further extension of the licenses through March 2026. Unless and until the moratorium is lifted, we will not be able to develop these assets.  Given this development, we fully impaired our investment in New Brunswick in 2016.
Acquisitions and Divestitures
In November 2020, we closed on our Agreement and Plan of Merger with Montage Resources Corporation (“Montage”), pursuant to which Montage merged with and into Southwestern (the “Montage Merger”). At the effective time of the Montage Merger, we acquired all of the outstanding shares of common stock in Montage in exchange for 1.8656 shares of our common stock per share of Montage common stock. The Montage Merger increased our footprint in West Virginia and Pennsylvania and expanded our operations into Ohio.
On August 30, 2018,September 1, 2021, we enteredclosed on our Agreement and Plan of Merger with Ikon Acquisition Company, LLC (“Ikon”), Indigo Natural Resources LLC (“Indigo”) and Ibis Unitholder Representative LLC, pursuant to which Indigo merged with and into an agreementIkon, a subsidiary of Southwestern, and became a subsidiary of Southwestern (the “Indigo Merger”). The outstanding equity interests in Indigo were cancelled and converted into the right to effect the Fayetteville Shale sale for $1,865 million, subject to customary adjustments.  In early December 2018, we completed the Fayetteville Shale sale, receiving $1,650receive (i) $373 million in net proceeds after adjustmentscash consideration, and (ii) 337,827,171 shares of Southwestern common stock. Additionally, we assumed $700 million in aggregate principal amount of Indigo’s 5.375% Senior Notes due 2029 (the “Indigo Notes”). The shares of Southwestern common stock had an aggregate dollar value equal to $1,588 million, based on the closing price of $4.70 per share of Southwestern common stock on the NYSE on September 1, 2021. The Indigo Merger diversified our operations by expanding our portfolio into the Haynesville and Bossier formations, deepened our inventory of economic wells, reduced our enterprise risk profile and gave us additional exposure to the purchaseLNG and other markets on the U.S. Gulf Coast.
On December 31, 2021, we closed on our Agreement and Plan of Merger with GEP Haynesville, LLC (“GEPH”), pursuant to which we acquired GEPH for aggregate consideration of approximately $1,732 million, consisting of a combination of $1,269 million cash and 99,337,748 shares of our common stock, with GEPH becoming our wholly owned subsidiary (the “GEPH Merger” and, together with the Montage Merger and the Indigo Merger, the “Mergers”). The shares issued as consideration had an aggregate dollar value equal to approximately $463 million based on the closing price of $215 million primarily due$4.66 per share of Southwestern common stock on the NYSE on December 31, 2021. The GEPH Merger furthered the benefits of the Indigo Merger and enhanced our scale and operating and marketing optionality in the Haynesville.
See Note 2 to the net cash flows fromconsolidated financial statements of this Annual Report for more information on the economic effective date of July 1, 2018 to the closing date.
During 2019, we sold non-core acreage for $38 million. There was no production or proved reserves associated with this acreage.Mergers.

We intend to use derivatives to limit the impact of adverse price volatilitymovements on a large portion of expected future production volumes to ensure certain desired levels of cash flow.  We refer you to Item 7A of Part II of this Annual Report, “Quantitative and Qualitative Disclosures about Market Risk,” for further information regarding our derivatives and risk management as of December 31, 2019.2021.
During 2019,2021, the average price we received for our natural gas production, excluding the impact of derivatives and including the cost of transportation, was approximately $0.65$0.53 per Mcf lower than average New York Mercantile Exchange, or NYMEX prices.prices, an improvement of 28% over the prior year differential.  Differences between NYMEX and price realized (basis differentials) are due primarily to locational differences and transportation cost. 
AsThe tables below present the amount of December 31, 2019, we have entered into physical sales arrangements to limitour future natural gas production in which the impact of basis volatility on approximately 165 Bcfhas been limited through derivatives and 50 Bcf of our 2020 and 2021 expected natural gas production, respectively, at a basis differential to NYMEX natural gas price of approximately ($0.04) per MMBtu and ($0.28) per MMBtu for 2020 and 2021, respectively.
We have also entered into financial basis swaps for approximately 198 Bcf, 86 Bcf and 45 Bcf of our 2020, 2021 and 2022 expected natural gas production, respectively, at a basis differential to NYMEX natural gas price of approximately ($0.31) per MMBtu, $0.04 per MMBtu and ($0.50) per MMBtu for 2020, 2021 and 2022, respectively,physical sales arrangements as of December 31, 2019.2021:

Delivery Commitments. As of December 31, 2019,2021, we had natural gas delivery commitments of 3151,224 Bcf in 20202022 and 83730 Bcf in 20212023 under existing agreements. These amounts are well below our expected 20202022 natural gas production from Northeast Appalachia and Southwest AppalachiaHaynesville and expected 20212023 production from our available reserves, which are not subject to any priorities or curtailments that may affect quantities delivered to our customers or any priority allocations or price limitations imposed by federal or state regulatory agencies, or any other factors beyond our control that may affect our ability to meet our delivery commitments other than those discussed in Item 1A “Risk Factors” of Part I of this Annual Report.  We expect to be able to fulfill all of our short-term and long-term delivery commitments to provide natural gas from our own production of available reserves; however, if we are unable to do so, we may have to purchase natural gas at market to fulfill our obligations.

Customers.  Our E&P production is marketed primarily by our Marketing segment.  Our customers include LNG exporters, major energy companies, utilities and industrial purchasers of natural gas.  DuringFor the year ended December 31, 2019, no single third-party2021, one purchaser accounted for 12% of our revenues. If we had completed the Indigo Merger and the GEPH Merger at the beginning of 2021, this same purchaser would have accounted for approximately 16% of our revenues. A default or operational disruption on this account could have a material impact on the Company.  For the year ended December 31, 2020, one purchaser accounted for 10% or more of our consolidated revenues.  For the years ended December 31, 2018 and 2017, two subsidiaries of Royal Dutch Shell Plc in aggregateNo other purchasers accounted for approximately 10.4% and 10.3%, respectively,more than 10% of total natural gas, oil and NGL sales.  We believe that the loss of any one customer would not have an adverse effect on our ability to sell our natural gas, oil and NGL production.consolidated revenues.
Competition
All phases of the natural gas and oilassociated liquids industry are highly competitive.  We compete in the acquisition and disposition of properties, the search for and development of reserves, the production and marketing of natural gas, oil and NGLs, and the securing of labor, services and equipment required to conduct our operations.  Our competitors include major oil and natural gas companies, other independent oil and natural gas companies and individual producers.  Many of these competitors have financial and other resources that substantially exceed those available to us.  Consequently, we will encounter competition that may affect both the price we receive and contract terms we must offer.  We also face competition in accessing pipeline and other services to transport our product to market.  Likewise, there are substitutes for the commodities we produce, such as other fuels for power generation, heating and transportation, and those markets in effect compete with us.
We cannot predict whether and to what extent any regulatory changes initiated by the Federal Energy Regulatory Commission, or the FERC, or any other new energy legislation or regulations will achieve the goal of increasing competition, lessening preferential treatment and enhancing transparency in markets in which our natural gas production is sold.  Similarly, we cannot predict whether legal constraints that have hindered the development of new transportation infrastructure, particularly in the northeastern United States, will continue.  However, we do not believe that we will be disproportionately affected as compared to other natural gas and oil producers and marketers by any action taken by the FERC or any other legislative or regulatory body or the status of the development of transportation facilities.
Regulation
Producing natural gas, oil and NGL resources and transporting and selling production historically have been heavily regulated.  For example, state governments regulate the location of wells and establish the minimum size for spacing units.  Permits typically are required before drilling.  State and local government zoning and land use regulations may also limit the locations for drilling and production.  Similar regulations can also affect the location, construction and operation of gathering

and other pipelines needed to transport production to market.  Regulations additionally govern the handling, transport and disposal of the water involved in our development efforts. In addition, various suppliers of goods and services may require licensing.
Currently in the United States, the price at which natural gas, oil or NGLs may be sold is not regulated.  Congress has imposed price regulation from time to time, and there can be no assurance that the current, less stringent regulatory approach will continue.  In 2015, the federal government repealed a 40-year ban on the export of crude oil.  The export of natural gas continues to require federal permits.  Broader freedom to export could lead to higher prices.  In addition, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and the rules that the U.S. Commodity Futures Trading Commission, (the “CFTC”), the SEC, and certain other regulators have issued thereunder regulate certain swaps, futures and options contracts in the major energy markets, including for natural gas, oil and NGLsNGLs.
Producing and transporting natural gas, oil and NGLs is also subject to extensive environmental regulation.  We refer you to “Other – Environmental Regulation” in Item 1 of Part 1 of this Annual Report and the risk factor “We, our service providers and our customers are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities” in Item 1A of Part I of this Annual Report for a discussion of the impact of environmental regulation on our business.

Constitution pipeline project that are reflected in the $8.5 billion of firm transportation obligations discussed above that were pending regulatory approval and/or construction.
As part of the Fayetteville Shale sale, we retained certain contractual commitments related to firm transportation, with the buyer obligated to pay the transportation provider directly for these charges.  As of December 31, 2019, approximately $108 million of these contractual commitments remain of which we will reimburse the buyer for certain of these potential obligations up to approximately $58 million through 2020 depending on the buyer’s actual use.  We have recorded a $46 million liability, which is the present value of the estimated future payments.  The buyer has also assumed future asset retirement obligations related to the operations sold.commitments.
In the first quarter of 2019, we agreed to purchase firm transportation with pipelines in Appalachia starting in 2021 and running through 2032 totaling $357$327 million in total remaining contractual commitments, of which the seller has agreed to reimburse us for $133$100 million.

Competition
Our marketing activities compete with numerous other companies offering the same services, many of which possess larger financial and other resources than we have.  Some of these competitors are other producers and affiliates of companies with extensive pipeline systems that are used for transportation from producers to end users. Other factors affecting competition are the cost and availability of alternative fuels, the level of consumer demand and the cost of and proximity to pipelines and other transportation facilities.  We believe that our ability to compete effectively within the marketing segment in the future depends upon establishing and maintaining strong relationships with customers.
Customers
Our marketing customers include LNG exporters, major energy companies, utilities and industrial purchasers of natural gas.  DuringFor the year ended December 31, 2019, no single third-party2021, one purchaser accounted for 12% of our revenues. If we had completed the Indigo Merger and the GEPH Merger at the beginning of 2021, this same purchaser would have accounted for approximately 16% of our revenues. A default or operational disruption on this account could have a material impact on the Company.  For the year ended December 31, 2020, one purchaser accounted for 10% or more of our consolidated revenues.  For the years ended December 31, 2018 and 2017, two subsidiaries of Royal Dutch Shell Plc in aggregateNo other purchasers accounted for approximately 10.4% and 10.3%, respectively,more than 10% of total natural gas, oil and NGL sales.  We believe that the loss of any one customer would not have an adverse effect on our ability to sell our natural gas, oil and NGL production.consolidated revenues.
Regulation
The transportation of natural gas, oil and NGLs is heavily regulated.  Interstate pipelines must obtain authorization fromFERC regulates the FERC to operate inrates and the terms and conditions of transportation service provided by interstate commerce,natural gas, crude oil and stateNGL pipelines. State governments typically must authorize the construction of pipelines for intrastate service. Moreover, the rates charged for intrastate transportation by pipeline are subject to regulation by state regulatory commissions.

Currently, all pipelines we own are intrastate and immaterial to our operations.
State and local permitting, zoning and land use regulations can affect the location, construction and operation of gathering and other pipelines needed to transport production to market, and the lack of new pipeline capacity can limit our ability to reach relevant markets for the sale of the commodities we produce.
The transportation of natural gas and oil is also subject to extensive environmental regulation.  We refer you to “Other – Environmental Regulation” in Item 1 of Part I of this Annual Report and the risk factor “We, our service providers and our customers are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or

Environmental Regulation
General.  Our operations are subject to environmental regulationlaws and regulations governing protection of the environment and natural resources in the jurisdictions in which we operate.  These laws and regulations require permits for drilling wells and the maintenance of bonding requirements to drill or operate wells, and also regulate the spacing and location of wells, the method of drilling and casing wells, the surface use and restoration of properties upon which wells are drilled, the plugging and abandoning of wells and the prevention and cleanup of pollutants and other matters.  We maintain insurance for clean-up costs in limited instances arising out of sudden and accidental events, but otherwise we may not be fully insured against all such risks.  Although future environmental obligations are not expected to have a material impact on the results of our operations or financial condition, there can be no assurance that future developments, such as increasingly stringent environmental laws or enforcement thereof, will not cause us to incur material environmental liabilities or costs.
Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal fines and penalties and the imposition of injunctive relief.  Certain laws and legal principles can make us liable for environmental damage to properties we previously owned, and, although we generally require purchasers to assume that liability, there is no assurance that they will have sufficient funds should a liability arise.  Changes in environmental laws and regulations occur frequently, and any changes may result in more stringent and costly waste handling, storage, transport,transportation, disposal or cleanup requirements.  We do not expect continued compliance with existing requirements to have a material adverse impact on us, but there can be no assurance that this will continue in the future.  We refer you to “Other – Environmental Regulation” in Item 1 of Part 1 of this Annual Report and the risk factor “We, our service providers and our customers are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities” in Item 1A of Part I of this Annual Report for a discussion of the impact of environmental regulation on our business.
The following is a summary of the more significant existing environmental and worker health and safety laws and regulations to which we are subject.
Generation and Disposal of Wastes. The Comprehensive Environmental Response, Compensation, and Liability Act, as amended, also known as CERCLA or the “Superfund law,” imposes liability, without regard to fault or the legality of the original conduct, on certain classes of persons that are considered to be responsible for the release of a “hazardous substance” into the environment.  These persons include the current or former owner or operator of a site where the release occurred, as well as persons that transported or disposed, or arranged for the transportation or disposal of, the hazardous substances found at the site.  Persons who are or were responsible for releases of hazardous substances under CERCLA may be subject to strict, joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment and for damages to natural resources, and it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment. 
The Resource Conservation and Recovery Act, as amended, or RCRA, generally does not regulate wastes generated by the exploration and production of natural gas and oil.  RCRA specifically excludes from the definition of hazardous waste “drilling fluids, produced waters and other wastes associated with the exploration, development or production of oil, natural gas or geothermal energy.”  However, legislative and regulatory initiatives have been considered from time to time that would reclassify certain natural gas and oil exploration and production wastes as “hazardous wastes,” which would make the reclassified wastes subject to much more stringent handling, disposal and clean-up requirements.  If such measures were to be enacted, it could have a significant impact on our operating costs.  Moreover, ordinary industrial wastes, such as paint wastes, waste solvents, laboratory wastes and waste oils, may be regulated as hazardous waste.
The Clean Water Act, as amended, or CWA, and analogous state laws, impose restrictions and strict controls regarding the discharge of produced waters and other natural gas and oil waste into regulated waters.  Permits must be obtained to discharge pollutants to regulated waters and to conduct construction activities in waters and wetlands. The CWA and similar state laws provide for civil, criminal and administrative penalties for any unauthorized discharges of pollutants and unauthorized discharges of reportable quantities of oil and other hazardous substances.  The EPA has adopted regulations requiring certain natural gas and oil exploration and production facilities to obtain permits for storm water discharges.  Costs may be associated with the treatment of wastewater or developing and implementing storm water pollution prevention plans.

The Oil Pollution Act, as amended, or OPA, and regulations promulgated thereunder impose a variety of requirements on “responsible parties” related to the prevention of oil spills and liability for damages resulting from such spills into regulated waters.  A “responsible party” includes the owner or operator of an onshore facility, pipeline or vessel, or the lessee or permittee of the area in which an offshore facility is located.  OPA assigns liability to each responsible party for oil cleanup costs and a variety of public and private damages.  Although liability limits apply in some circumstances, a party cannot take advantage of liability limits if the spill was caused by gross negligence or willful misconduct or resulted from violation of a federal safety,
21

construction or operating regulation.  If the party fails to report a spill or to cooperate fully in the cleanup, liability limits likewise do not apply.  Few defenses exist to the liability imposed by OPA.  OPA imposes ongoing requirements on a responsible party, including the preparation of oil spill response plans and proof of financial responsibility to cover environmental cleanup and restoration costs that could be incurred in connection with an oil spill.  Although oilOil accounted for only 4%3% of our total production in 20192021 and 2%4% in 20182020 and 2017, we expect this percentage to increase as we continue to develop our Southwest Appalachia assets.2019.
We own or lease, and have in the past owned or leased, onshore properties that for many years have been used for or associated with the exploration for and production of natural gas and oil.  Although we have utilized operating and disposal practices that were standard in the industry at the time, hydrocarbons or other wastes may have been disposed of or released on or under the properties owned or leased by us and/or on or under other locations where such wastes have been taken for disposal. In addition, some of these properties have been operated by third parties whose treatment and disposal or release of wastes was not under our control.  Under CERCLA, the CWA, RCRA and analogous state laws, we could be required to remove or remediate previously disposed wastes (including waste disposed of or released by prior owners or operators) or property contamination (including groundwater contamination by prior owners or operators), or to perform remedial plugging or closure operations to prevent future contamination.
Air Emissions. The Clean Air Act, as amended, restricts emissions into the atmosphere. Various activities inwe conduct as part of our operations, such as drilling, pumping and the use of vehicles, can release matter subjectresult in emissions to regulation.the environment. We must obtain permits, typically from local authorities, to conduct various regulated activities. Federal and state governmental agencies are looking into the issues associated withtaking steps to regulate methane and other emissions from oil and natural gas activities, and further regulation could increase our costs or restrict our ability to produce. AlthoughFor example, on November 15, 2021, the U.S. Environmental Protection Agency (“EPA”) issued a proposed rule under the Clean Air Act’s New Source Performance Standards (“NSPS”), known as Subpart OOOOa, which is intended to reduce methane emissions from new and existing oil and gas sources. The proposed rule would make the existing regulations in Subpart OOOOa more stringent and create a Subpart OOOOb to expand reduction requirements for new, modified, and reconstructed oil and gas sources, including standards focusing on certain source types that have never been regulated under the CAA (including intermittent vent pneumatic controllers, associated gas, and liquids unloading facilities). In addition, the proposed rule would establish “Emissions Guidelines,” creating a Subpart OOOOc that would require states to develop plans to reduce methane emissions from existing sources that must be at least as effective as presumptive standards set by the EPA. Under the proposed rule, states would have three years to develop their compliance plan for existing sources and the regulations for new sources would take effect immediately upon issuance of a final rule. The EPA is expected to issue both a supplemental proposed rule, that may expand or modify the current proposed rule, and final rule by the end of 2022. In addition, although methane emissions are not currently regulated at the federal level, we are required to report emissions of various greenhouse gases, including methane.
Threatened and Endangered Species. The Endangered Species Act and comparable state laws protect species threatened with possible extinction.  Protection of threatened and endangered species may have the effect of prohibiting or delaying us from obtaining drilling and other permits and may include restrictions on road building and other activities in areas containing the affected species or their habitats.  Based on the species that have been identified and listed to date, we do not believe there are any species protected under the Endangered Species Act that would materially and adversely affect our operations at this time.
Hydraulic Fracturing.  We utilize hydraulic fracturing in drilling wells as a means of maximizing their productivity.  It is an essential and common practice in the oil and gas industry used to stimulate the production of oil, natural gas, and associated liquids from dense and deep rock formations.  Hydraulic fracturing involves using water, sand, and certain chemicals to fracture the hydrocarbon-bearing rock formation to allow the flow of hydrocarbons into the wellbore.
In the past several years, there has been an increased focus on the environmental aspects of hydraulic fracturing, practice, both in the United States and abroad. In the United States, hydraulic fracturing is typically regulated by state oil and natural gas commissions, but federal agencies have started to assert regulatory authority over certain aspects of the process. For example,In addition to the Environmental Protection Agency, or EPA, issued final rules effective as of October 15, 2012 that subject oil and gas operations (production, processing, transmission, storage and distribution) to regulation under the New Source Performance Standards, or NSPS, and National Emission Standards for Hazardous Air Pollutants, or NESHAPS programs.  In May 2016,EPA’s Subpart OOOO regulations discussed above, the EPA finalized additional regulations to control methane and volatile organic compound (“VOC”) emissions from certain oil and gas equipment and operations.  In September 2018, the EPA issued proposed revisions to those regulations, which, if finalized, would reduce certain obligations thereunder.  Later, in August 2019, the EPA proposed two options for rescinding the regulations. Under the EPA’s preferred alternative, the agency would rescind the methane limits for new, reconstructed and modified oil and natural gas production sources while leaving in place the general emission limits for VOCs, and relieve the EPA of its obligation to develop guidelines for methane emissions from existing sources. In addition, the proposal would remove from the oil and natural gas category the natural gas transmission and storage segment. The other proposed alternative would rescind the methane requirements of the NSPS applicable to all oil and natural gas sources, without removing any sources from that source category (and still requiring control of VOCs in general). The EPA also finalized pretreatment standards that would prohibit the indirect discharge of wastewater from onshore unconventional oil and gas extraction facilities to publicly owned treatment works. Based on our current operations and practices, management believes such newly promulgated rules will not have a material adverse impact on our financial position, results of operations or cash flows but these matters are subject to inherent uncertainties and management’s view may change in the future.

In addition, there are certain governmental reviews either underway or proposed that focus on environmental aspects of hydraulic fracturing practices.  A number of federal agencies are analyzing, or have been requested to review, a variety of environmental issues associated with hydraulic fracturing.  For example, in December 2016, the EPA released its finala report regarding the potential impacts of hydraulic fracturing on drinking water resources, concluding that “water cycle” activities
22

Table of Contents
Index to Financial Statements
associated with hydraulic fracturing may impact drinking water resources under certain circumstances such as water withdrawals for fracturing in times or areas of low water availability, surface spills during the management of fracturing fluids, chemicals or produced water, injection of fracturing fluids into wells with inadequate mechanical integrity, injection of fracturing fluids directly into groundwater resources, discharge of inadequately treated fracturing wastewater to surface waters and disposal or storage of fracturing wastewater in unlined pits.  The results of these studies could lead federal and state governments and agencies to develop and implement additional regulations.
Although the current federal administration has relaxed many regulations adopted in the latter part of the prior administration, someSome states in which we operate have adopted, and other states are considering adopting, regulations that could impose more stringent permitting, public disclosure, waste disposal and well construction requirements on hydraulic fracturing operations or otherwise seek to ban fracturing activities altogether.  In addition to state laws, local land use restrictions, such as city ordinances, may restrict or prohibit the performance of well drilling in general and/or hydraulic fracturing in particular.  In the event state, local, or municipal legal restrictions are adopted in areas where we are currently conducting, or in the future plan to conduct, operations, we may incur additional costs to comply with such requirements that may be significant in nature, experience delays or curtailment in the pursuit of exploration, development, or production activities, and perhaps even be precluded from the drilling and/or completion of wells.
Increased regulation and attention given to the hydraulic fracturing process has led to greater opposition, including litigation, to oil and gas production activities using hydraulic fracturing techniques.  Additional legislation or regulation could also lead to operational delays or increased operating costs in the production of oil, natural gas, and associated liquids including from the development of shale plays, or could make it more difficult to perform hydraulic fracturing.  The adoption of additional federal, state or local laws or the implementation of regulations regarding hydraulic fracturing could potentially cause a decrease in the completion of new oil and gas wells and increased compliance costs and time, which could adversely affect our financial position, results of operations and cash flows.  In addition, various officials and candidates at the federal, state and local levels, including somepast presidential candidates, have proposed banning hydraulic fracturing altogether. We refer you to the risk factor “We, our service providers and our customers are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities” in Item 1A of Part I of this Annual Report.
In addition, concerns have been raised about the potential for seismic activity to occur from the use of underground injection control wells, a predominant method for disposing of waste water from oil and gas activities.  New rules and regulations may be developed to address these concerns, possibly limiting or eliminating the ability to use disposal wells in certain locations and increasing the cost of disposal in others.  We utilize third parties to dispose of waste water associated with our operations.  These third parties may operate injection wells and may be subject to regulatory restrictions relating to seismicity.seismicity, which could result in increased costs for their services to dispose of waste water from our operations. 
Greenhouse Gas Emissions.Emissions and Climate Change.  In response to findings that emissions of carbon dioxide, methane and other greenhouse gases present an endangerment to human health and the environment, the EPA has adopted regulations under existing provisions of the federal Clean Air Act that, among other things, establish Prevention of Significant Deterioration, or PSD, construction and Title V operating permit reviews for certain large stationary sources.  Facilities required to obtain PSD permits for their greenhouse gas emissions also will be required to meet “best available control technology” standards that will be established on a case-by case basis.  One of our subsidiaries operates compressor stations, which are facilities that are required to adhere to the PSD or Title V permit requirements.  EPA rulemakings related to greenhouse gas emissions could adversely affect our operations and restrict or delay our ability to obtain air permits for new or modified sources.
The EPA also has adopted rules requiring the monitoring and reporting of greenhouse gas emissions from specified onshore and offshore oil and gas production sources in the United States on an annual basis, which include certain of our operations.  Although Congress from time to time has considered legislation to reduce emissions of greenhouse gases, there has not been significant activity in the form of adopted legislation to reduce greenhouse gas emissions at the federal level in recent years.  However, the United States House of Representatives passed H.R. 5376, known as the Build Back Better Act on November 3, 2021. The House version of the bill targets methane emissions from oil and gas sources by proposing to implement fees for excess methane leaking from wells, storage sites and pipelines as well as fees for new producing and non-producing oil and gas leases and offshore pipelines. The United States Senate did not pass the House version of the Build Back Better Act, and it is unclear whether any portions of the bill will become law. In the absence of such federal climate legislation, a number of states, including states in which we operate, have enacted or passed measures to track and reduce emissions of greenhouse gases, primarily through the planned development of greenhouse gas emission inventories and regional greenhouse gas cap-and-trade
30

programs.  Most of these cap-and-trade programs require major sources of emissions or major producers of fuels to acquire and surrender emission allowances, with the number of allowances available for purchase reduced each year until the overall greenhouse gas emission reduction goal is achieved.  These reductions may cause the cost of allowances to escalate significantly over time.
The adoption and implementation of regulations that require reporting of greenhouse gases or otherwise limit emissions of greenhouse gases from our equipment and operations could require us to incur increased operating costs, including costs to monitor and report on greenhouse gas emissions, or install new equipment to reduce emissions of greenhouse gases associated with our operations.operations, acquire emissions allowances or comply with new regulatory requirements.  In addition, these regulatory initiatives could drive down demand for our products, by stimulating demand for alternative forms of energy that do not

rely on combustion of fossil fuels that serve as a major source of greenhouse gas emissions, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.  At the same time,While some new laws and regulations are prompting power producers to shift from coal to natural gas, which is increasing demand.has a positive effect on demand, regulatory incentives or requirements to conserve energy, use alternative sources or reduce greenhouse gas emissions in product supply chains could reduce demand for the products we produce.
Further, inIn December 2015, over 190 countries, including the United States, reached an agreement to reduce global greenhouse gas emissions (the “Paris Agreement”). The Paris Agreement entered into effect in November 2016 after more than 70 nations, including the United States, ratified or otherwise indicated their intent to be bound by the agreement. InOn June 1, 2017, President Trumpthe prior administration announced that the United States intends toU.S. would withdraw from the Paris Agreement, andwhich withdrawal became effective on November 4, 2020. However, on January 20, 2021, the current administration issued written notification to seek negotiations either to reenter the Paris Agreement on different terms or a separate agreement.  In August 2017, the U.S. Department of State officially informed the United Nations of the intent of the United StatesStates’ intention to withdraw fromrejoin the Paris Agreement, andwhich became effective on February 19, 2021. In addition, in November 2019September 2021, the current administration publicly announced the Global Methane Pledge, a pact that aims to reduce global methane emissions at least 30% below 2020 levels by 2030. Since its formal launch at the United States initiatedNations Climate Change Conference (“COP26”), over 100 countries have joined the year-long process of formally withdrawing, which would result in an effective exit date of November 2020.  The United States’ adherence to the exit process and/or the terms on which the United States may re-enter the Paris Agreement or a separately negotiated agreement are unclear at this time.pledge. To the extent that the United States and other countries implement this agreement or impose other climate change regulations on the oil and gas industry, it could have an adverse effect on our business.
The Company is committed to responsible energy development, and we recognize stakeholder concerns about climate change. We also understand that regulations and practices aimed at protecting the environment, and specifically reducing greenhouse gas emissions, can affect our business. We consider addressing these issues as part of our risk management process. We have published a climate change scenario analysis as a part of our 2021 Corporate Responsibility Report (which covers the year 2020 and is not incorporated by reference into this filing). This report and our corporate responsibility reporting is informed by recommendations from the Task Force on Climate-Related Financial Disclosures framework.
Employee Health and Safety. Our operations are subject to a number of federal and state laws and regulations, including the federal Occupational Safety and Health Act, or OSHA, and comparable state statutes, whose purpose is to protect the health and safety of workers. In addition, the OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of the federal Superfund AmendmentAmendments and Reauthorization Act and comparable state statutes require that information be maintained concerning hazardous materials used or produced in operations and that this information be provided to employees, state and local government authorities and citizens.
Canada. Our activities in Canada have, to date, been limited to certain geological and geophysical activities and now are subject to a moratorium.  If and when the moratorium ends and should we begin drilling and development activities in New Brunswick, we will be subject to Canadian federal, provincial and local environmental regulations.

ITEM 1A. RISK FACTORS
You should carefully consider the following risk factors in addition to the other information included in this Annual Report.  Each of these risk factors could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our common stock.
Risks Related to Our Business
Natural gas, oil and NGL prices and basis differentials greatly affect our revenues and thus profits, liquidity, growth, ability to repay our debt and the value of our assets.
Our revenues, profitability, liquidity, growth, ability to repay our debt and the value of our assets greatly depend on prices for natural gas, oil and NGLs.  The markets for these commodities are volatile, and we expect that volatility to continue.  The prices of natural gas, oil and NGLs fluctuate in response to changes in supply and demand (global, regional and local), transportation costs, market uncertainty and other factors that are beyond our control.  Short- and long-term prices are subject to a myriad of factors such as:
overall demand, including the relative cost of competing sources of energy or fuel;
overall supply, including costs of production;
the availability, proximity and capacity of pipelines, other transportation facilities and gathering, processing and storage facilities;
regional basis differentials;
national and worldwide economic and political conditions;
weather conditions and seasonal trends;
government regulations, such as regulation of natural gas transportation and price controls;
inventory levels; and
market perceptions of future prices, whether due to the foregoing factors or others.
For example, in 20182021 and 2019,2020, the NYMEX settlement price for natural gas ranged from a low of $2.14$1.50 per MMBtu in August 2019July 2020 to a high of $4.72$6.20 per MMBtu in December 2018,November 2021, and during this periodthese periods our production was 85%82% and 78%79% natural gas, respectively.  NGLs represent a growing part of our business, and in the same period prices for ethane and propane, our two principal NGL products, ranged from $6.12 per Bbl in July 2019 to $22.13 per Bbl in September 2018 and $16.92 per Bbl in August 2019 to $44.47 per Bbl in September 2018, respectively.  Although we hedge a large portion of our production against changing prices, derivatives do not protect all our future volumes, may result in our forgoing profit opportunities if markets rise and, for NGLs, are not always available for substantial periods into the future.  In 2019,2021, we received $180paid $1,492 million, net of amounts we paid,received, in settlement of hedging arrangements. Moreover, when market expectations of future prices fall, as they did in 2019, the prices at which we can hedge are lower, reducing future revenue.arrangements due to increased commodity pricing.
Lower natural gas, oil and NGL prices directly reduce our revenues and thus our operating income and cash flow.  Lower prices also reduce the projected profitability of further drilling and therefore are likely to reduce our drilling activity, which in turn means we will have fewer wells on production in the future.  Lower prices also reduce the value of our assets, both by a direct reduction in what the production would be worth and by making some properties uneconomic, resulting in non-cash impairments to the recorded value of our reserves and non-cash charges to earnings.  For example, in 2016,2020, we reported non-cash impairment charges on our natural gas and oil properties totaling $2.3 billion,$2,825 million, primarily resulting from decreases in trailing 12-month average first-day-of-the-month natural gas prices throughout 2016,2020, as compared to 2015, and the non-cash impairment of certain undeveloped leasehold interests.  Given the fall in2019.  Although general commodity prices increased in 2019 and early 2020 and assuming that commodity prices remain at January 2020 levels for the rest of the first quarter of 2020, we expect a2021, further non-cash impairment to our natural gas and oil properties in the first quarter of 2020 ranging from approximately $400 million to $600 million, net of tax. Further non-cash

impairments in future periods could occur if the trailing 12-month commodity prices decrease as compared to the average used in prior periods.
As of December 31, 2019,2021, we had $2.3$5.4 billion of debt outstanding, consisting principally of senior notes maturing in various increments from 2022 to 2032, $550 million of term loan borrowings maturing in 2027 and $34$460 million of borrowings under our revolving2018 credit facility (defined below), which matures in 2024.  At current commodity price levels, our net cash flow from operations is substantially higher than our interest obligations under this debt, but significant drops in realized prices could affect our ability to pay our current obligations or refinance our debt as it becomes due.
Moreover, general industry conditions may make it difficult or costly to refinance increments of this debt as it matures.  Although our indentures do not contain significant covenants restricting our operations and other activities, our bank credit agreements contain financial covenants with which we must comply.  We refer you to the risk factor “Our current and future levels of indebtedness may adversely affect our results and limit our growth.”  Our inability to pay our current obligations or refinance our debt as it becomes due could have a material and adverse effect on our company.

prices, sincesuch as was generally experienced from 2014 has reducedto 2020, could reduce our revenues, profits and cash flow, causedcause us to record significant non-cash asset impairments and ledlead us to reduce both our level of capital investing and our workforce, which has caused us to incur significant expenses relating to employee terminations.  Further price decreases could have similar consequences.  Similarly, a rise in prices to levels experienced before 2015 could significantly increase our revenues, profits and cash flow, which could be used to expand capital investments.workforce.
Significant capital investment is required to develop and replace our reserves and conduct our business.
Our activities require substantial capital investment, not only to expand revenues but also because production from existing wells and thus revenues declines each year.  We intend to fund our future capital investing through net cash flows from operations, net of changes in working capital, supplemented on occasion by funds earmarked from the net proceeds of significant transactions, such as the Fayetteville Shale sale, which in the meantime were used to reduce outstanding debt.capital.  Our ability to generate operating cash flow is subject to many of the risks and uncertainties that exist in our industry, some of which we may not be able to anticipate at this time.  Future cash flows from operations are subject to a number of risks and variables, such as the level of production from existing wells, prices of natural gas, oil and NGLs, our success in developing and producing new reserves and the other risk factors discussed herein.  If we are unable to fund capital investing, we could experience a further reduction in drilling new wells, acquiring new acreage and a loss of existing leased acreage, resulting in a decline in our cash flow from operations and natural gas, oil and NGL production and reserves. 
If we are not able to develop and replace reserves, our production levels and thus our revenues and profits may decline.
Production levels from existing wells decline over time, and drilling new wells requires an inventory of leases and other rights with reserves that have not yet been drilled.  Our future success depends largely upon our ability to find, develop or acquire additional natural gas, oil and NGL reserves that are economically recoverable.  Unless we replace the reserves we produce through successful development, acquisition or exploration activities, our proved reserves and production will decline over time.  Identifying and exploiting new reserves requires significant capital investment and successful drilling operations.  Thus, our future natural gas, oil and NGL reserves and production, and therefore our revenues and profits, are highly dependent on our level of capital investments, our success in efficiently developing our current reserves and economically finding or acquiring additional recoverable reserves.
Our business depends on access to natural gas, oil and NGL gathering, processing and transportation systems and facilities. Changes to access and cost of these systems and facilities could adversely impact our business and financial condition. Our commitments to assure availability of transportation could lead to substantial payments for capacity we do not use if production falls below projected levels.
The marketability of our natural gas, oil and NGL production depends in large part on the operation, availability, proximity, capacity and expansion of transportation systems and facilities owned by third parties.  For example, we can provide no assurance that sufficient transportation capacity will exist for expected production from Appalachia or Haynesville, or that we will be able to obtain sufficient transportation capacity on economic terms.  During the past few years, several planned pipelines intended to service production in the Northeast United States have experienced delays in their in-service dates due to regulatory delays and litigation.
Producers compete by lowering their sales prices, resulting in the locational differences from NYMEX pricing.  Further, a lack of available capacity on transportation systems and facilities or delays in their planned expansions could result in the shut-in of producing wells or the delay or discontinuance of drilling plans for properties.  A lack of availability of these systems and facilities for an extended period of time could negatively affect our revenues.  In addition, we have entered into contracts for firm transportation and any failure to renew those contracts on the same or better commercial terms could increase our costs and our exposure to the risks described above.

We have entered into gathering agreements in producing areas and multiple long-term firm transportation agreements relating to natural gas volumes from all our producing areas. As of December 31, 2019,2021, our aggregate demand charge commitments under these firm transportation agreements and gathering agreements were approximately $8.5$10.5 billion. If our development programs fail to produce sufficient quantities of natural gas and ethane to fill the contracted capacity within expected timeframes, we would be required to pay demand or other charges for transportation on pipelines and gathering systems for capacity that we would not be fully utilizing. In those situations, which have occurred on a small scale at various times, we endeavor to sell or transfer that capacity to others or fill the excess capacity with production purchased from third parties. There can be no assurance that these measures will recoup the full cost of the unused transportation.
A downgrade in our credit rating could negatively impact our cost of and ability to access capital and our liquidity.
Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, could impact our ability to access debt markets in the future to refinance existing debt or obtain additional funds, affect the market value of our senior notes and increase our borrowing costs.  Such ratings are limited in scope, and do not address all material risks relating to us, but rather reflect only the view of each rating agency of the likelihood we will be able to repay our debt at the time the rating is issued.  An explanation of the significance of each rating may be obtained from the applicable rating agency.  As of February 25, 2020, our long-term issuer ratings were Ba2 by Moody’s, BB by Standard and Poor’s and BB by Fitch Investor Services.  There can be no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant.
Actual downgrades in our credit ratings may also impact our interest costs and liquidity.  The interest rates under certain of our senior notes increases as credit ratings fall. Many of our existing commercial contracts contain, and future commercial contracts may contain, provisions permitting the counterparty to require increased security upon the occurrence of a downgrade in our credit rating.  Providing additional security, such as posting letters of credit, could reduce our available cash or our liquidity under our revolving credit facility for other purposes.  We had $172 million of letters of credit outstanding at December 31, 2019.  The amount of additional financial assurance would depend on the severity of the downgrade from the credit rating agencies, and a downgrade could result in a decrease in our liquidity.
Strategic determinations, including the allocation of capital and other resources to strategic opportunities, are challenging in the face of shifting market conditions, and our failure to appropriately allocate capital and resources among our strategic opportunities may adversely affect our financial condition and reduce our future growth rate.
We necessarily must consider future price and cost environments when deciding how much capital we are likely to have available from net cash flow and how best to allocate it.  Our current philosophy is to generally operate within cash flow from operations, net of changes in working capital, supplemented in 2019 and 2020 with earmarked proceeds from the sale of our Fayetteville Shale assets in December 2018, and to invest capital in a portfolio of projects that are projected to generate the

highest combined PVI.Internal Rate of Return.  Volatility in prices and potential errors in estimating costs, reserves or timing of production of the reserves can result in uneconomic projects or economic projects generating less than anticipated returns.
Certain of our undeveloped assets are subject to leases that will expire over the next several years unless production is established on units containing the acreage.
Approximately 9,39964,030 and 35,9249,101 net acres of our Northeast Appalachia and Southwest AppalachiaHaynesville acreage, respectively, will expire in the next three years if we do not drill successful wells to develop the acreage or otherwise take action to extend the leases.  Our ability to drill wells depends on a number of factors, including certain factors that are beyond our control, such as the ability to obtain permits on a timely basis or to compel landowners or lease holders on adjacent properties to cooperate.  Further, we may not have sufficient capital to drill all the wells necessary to hold the acreage without increasing our debt levels, or given price projections at the time, drilling may not be projected to achieve a sufficient return or be judged to be the best use of our capital.  To the extent we do not drill the wells, our rights to acreage can be lost.
Ourproved natural gas, oil and NGL reserves are estimates that include uncertainties.  Any material changes to these uncertainties or underlying assumptions could cause the quantities and net present value of our reserves to be overstated or understated.
As described in more detail under “Critical Accounting Policies and Estimates – Natural Gas and Oil Properties” in Item 7 of Part II of this Annual Report, our reserve data represents the estimates of our reservoir engineers made under the supervision of our management, and our reserve estimates are audited each year by Netherland, Sewell & Associates, Inc., or NSAI, an independent petroleum engineering firm.  Reserve engineering is a subjective process of estimating underground accumulations of natural gas, oil and NGLs that cannot be measured in an exact manner.  The process of estimating quantities of proved reserves is complex and inherently imprecise, and the reserve data included in this document are only estimates.  The process relies on interpretations of available geologic, geophysical, engineering and production data.  The extent, quality and reliability of this technical data can vary.  The process also requires certain economic assumptions, some of which are mandated by the SEC, such as using historic natural gas, oil and NGL prices rather than future projections.  Additional assumptions include drilling and operating expenses, capital investing, taxes and availability of funds. Furthermore, different reserve engineers may make different estimates of reserves and cash flows based on the same data.
Results of drilling, testing and production subsequent to the date of an estimate may justify revising the original estimate.  Accordingly, initial reserve estimates often vary from the quantities of natural gas, oil and NGLs that are ultimately recovered, and such variances may be material.  Any significant variance could reduce the estimated quantities and present value of our reserves.
You should not assume that the present value of future net cash flows from our proved reserves is the current market value of our estimated natural gas, oil and NGL reserves.  In accordance with SEC requirements, we base the estimated discounted future net cash flows from our proved reserves on the preceding 12-month average natural gas, oil and NGL index prices, calculated as the unweighted arithmetic average for the first day of the month price for each month and costs in effect on the date of the estimate, holding the prices and costs constant throughout the life of the properties.  Actual future prices and costs may differ materially from those used in the net present value estimate, and future net present value estimates using then current prices and costs may be significantly less than the current estimate.  In addition, the 10% discount factor we use when calculating discounted future net cash flows for reporting requirements in compliance with the applicable accounting standards may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with us or the oil and gas industry in general.
Natural gas and oil drilling and producing and transportation operations are complex and can be hazardous and may expose us to liabilities. Incidents related to HSE performance and our asset and operating integrity could adversely impact our business and financial condition.
Drilling and production operations are subject to many risks, including well blowouts, cratering and explosions, pipe failures, fires, formations with abnormal pressures, uncontrollable flows of oil, natural gas, brine or well fluids, severe weather, natural disasters, groundwater contamination and other environmental hazards and risks.  Some of these risks or hazards could materially and adversely affect our revenues and expenses by reducing or shutting in production from wells, loss of equipment or otherwise negatively impacting the projected economic performance of our prospects. If any of these risks occurs, we could sustain substantial losses as a result of:
injury or loss of life;

severe damage to or destruction of property, natural resources or equipment;
pollution or other environmental damage;

clean-up responsibilities;
regulatory investigations and administrative, civil and criminal penalties; and
injunctions resulting in limitation or suspension of operations.
For our properties that we do not operate, we depend on the operator for operational and regulatory compliance.
We rely on third parties to transport our production to markets.  Their operations, and thus our ability to reach markets, are subject to all of the risks and operational hazards inherent in transporting natural gas and ethane and natural gas compression, including:
damages to pipelines, facilities and surrounding properties caused by third parties, severe weather, natural disasters, including hurricanes, and acts of terrorism;
maintenance, repairs, mechanical or structural failures;
damages to, loss of availability of and delays in gaining access to interconnecting third-party pipelines;
disruption or failure of information technology systems and network infrastructure due to various causes, including unauthorized access or attack; and
leaks of natural gas or ethane as a result of the malfunction of equipment or facilities.
A material event such as those described above could expose us to liabilities, monetary penalties or interruptions in our business operations.  Although we may maintain insurance against some, but not all, of the risks described above, our insurance may not be adequate to cover casualty losses or liabilities, and our insurance does not cover penalties or fines that may be assessed by a governmental authority.  Also, in the future we may not be able to obtain insurance at premium levels that justify its purchase.
Ourcurrent and future levels of indebtedness may adversely affect our results and limit our growth.
At December 31, 2019, we had long-term indebtedness of $2.3 billion.  The terms of the indentures governing our outstanding senior notes, our credit facilities, and the lease agreements relating to our drilling rigs, other equipment and headquarters building, which we collectively refer to as our “financing agreements,” impose restrictions on our ability and, in some cases, the ability of our subsidiaries to take a number of actions that we may otherwise desire to take, which may include, without limitation, one or more of the following:
incurring additional debt;
redeeming stock or redeeming certain debt;
making certain investments;
creating liens on our assets; and
selling assets.
The revolving credit facility we entered into in April 2018, as amended (our “revolving credit facility”), contains customary representations, warranties and covenants including, among others, the following covenants:
a prohibition against incurring debt, subject to permitted exceptions;
a restriction on creating liens on assets, subject to permitted exceptions;
restrictions on mergers and asset dispositions;
restrictions on use of proceeds, investments, transactions with affiliates, or change of principal business; and

maintenance of the following financial covenants, commencing with the fiscal quarter ended June 30, 2018:
1.Minimum current ratio of no less than 1.00 to 1.00, whereby current ratio is defined as the Company’s consolidated current assets (including unused commitments under the credit agreement, but excluding non-cash derivative assets) to consolidated current liabilities (excluding non-cash derivative obligations and current maturities of long-term debt).
2.Maximum total net leverage ratio of no greater than (i) with respect to each fiscal quarter ending during the period from June 30, 2018 through March 31, 2019, 4.50 to 1.00, (ii) with respect to each fiscal quarter ending during the period from June 30, 2019 through March 31, 2020, 4.25 to 1.00, and (iii) with respect to each fiscal quarter ending on or after June 30, 2020, 4.00 to 1.00.  Total net leverage ratio is defined as total debt less cash on hand (up to the lesser of 10% of credit limit or $150 million) divided by consolidated EBITDAX for the last four consecutive quarters.  EBITDAX, as defined in our revolving credit facility, excludes the effects of interest expense, depreciation, depletion and amortization, income tax, any non-cash impacts from impairments, certain non-cash hedging activities, stock-based compensation expense, non-cash gains or losses on asset sales, unamortized issuance cost, unamortized debt discount and certain restructuring costs. 
As of December 31, 2019, we were in compliance with all of the covenants of our revolving credit facility in all material respects. Our ability to comply with these financial covenants depends in part on the success of our development program and upon factors beyond our control, such as the market prices for natural gas, oil and NGLs.
Our level of indebtedness and off-balance sheet obligations, and the covenants contained in our financing agreements, could have important consequences for our operations, including:
requiring us to dedicate a substantial portion of our cash flow from operations to required payments, thereby reducing the availability of cash flow for working capital, capital investing and other general business activities;
limiting our ability to obtain additional financing in the future for working capital, capital investing, acquisitions and general corporate and other activities;
limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and
detracting from our ability to successfully withstand a downturn in our business or the economy generally.
Any significant reduction in the borrowing base under our revolving credit facility may negatively impact our ability to fund our operations, and we may not have sufficient funds to repay borrowings under our revolving credit facility if required as a result of a borrowing base redetermination.
The amount we may borrow under our revolving credit facility is capped at the lower of the total of our bank commitments and a “borrowing base” determined from time to time by the lenders based on our reserves, market conditions and other factors.  As of December 31, 2019, the borrowing base was $2.1 billion, which was most recently reaffirmed as of October 8, 2019 and is above the total current commitments of $2.0 billion.  The borrowing base is subject to scheduled semiannual and other elective collateral borrowing base redeterminations based on our natural gas, oil and NGL reserves and other factors.  As of December 31, 2019, we had $34 million of outstanding borrowings under our revolving credit facility, and we expect to borrow under that facility in the future.  As of December 31, 2019, we had $172 million of letters of credit issued under the credit facility and unused borrowing capacity was approximately $1.8 billion.  Any significant reduction in our borrowing base as a result of borrowing base redeterminations or otherwise may negatively impact our liquidity and our ability to fund our operations and, as a result, may have a material adverse effect on our financial position, results of operation and cash flow.  Further, if the outstanding borrowings under our revolving credit facility were to exceed the borrowing base as a result of any such redetermination or other reasons, we would be required to repay the excess within a brief period.  We may not have sufficient funds to make such repayments.  If we do not have sufficient funds and we are otherwise unable to negotiate renewals of our borrowings or arrange new financing, we may have to sell significant assets.  Any such sale could have a material adverse effect on our business and financial results.
Our ability to comply with the covenants and other restrictions in our financing agreements may be affected by events beyond our control, including prevailing economic and financial conditions.
Failure to comply with the covenants and other restrictions could lead to an event of default and the acceleration of our obligations under our senior notes, credit facilities or other financing agreements, and in the case of the lease agreements for drilling rigs, compressors and pressure pumping equipment, loss of use of the equipment.  In particular, the occurrence of risks identified elsewhere in this section, such as declines in commodity prices, increases in basis differentials and inability to access

markets, could reduce our profits and thus the cash we have to fulfill our financial obligations.  If we are unable to satisfy our obligations with cash on hand, we could attempt to refinance such debt, sell assets or repay such debt with the proceeds from an equity offering.  We cannot assure that we will be able to generate sufficient cash flow to pay the interest on our debt, to meet our lease obligations, or that future borrowings, equity financings or proceeds from the sale of assets will be available to pay or refinance such debt or obligations.  The terms of our financing agreements may also prohibit us from taking such actions. Factors that will affect our ability to raise cash through an offering of our capital stock, a refinancing of our debt or a sale of assets include financial market conditions and our market value and operating performance at the time of such offering or other financing.  We cannot assure that any such proposed offering, refinancing or sale of assets can be successfully completed or, if completed, that the terms will be favorable to us.
We have made significant investments in oilfield service businesses, including our drilling rigs, water infrastructure and pressure pumping equipment, to lower costs and secure inputs for our operations and transportation for our production.  If our development and production activities are curtailed or disrupted, we may not recover our investment in these activities, which could adversely impact our results of operations.  In addition, our continued expansion of these operations may adversely impact our relationships with third-party providers.
We also have made investments to meet certain of our field services’ needs, including establishing our own drilling rig operation, water transportation system in Southwest Appalachia and pressure pumping capability. If our level of operations is reduced for a long period, we may not be able to recover these investments.  Further, our presence in these service and supply sectors, including competing with them for qualified personnel and supplies, may have an adverse effect on our relationships with our existing third-party service and resource providers or our ability to secure these services and resources from other providers.
Our business depends on the availability of water and the ability to dispose of water.  Limitations or restrictions on our ability to obtain or dispose of water may have an adverse effect on our financial condition, results of operations and cash flows.
Water is an essential component of drilling and hydraulic fracturing processes.  Limitations or restrictions on our ability to secure sufficient amounts of water, or to dispose of or recycle water after use, could adversely impact our operations.  In some cases, water may need to be obtained from new sources and transported to drilling sites, resulting in increased costs.  Moreover, the introduction of new environmental initiatives and regulations related to water acquisition or waste water disposal, including produced water, drilling fluids and other wastes associated with the exploration, development or production of hydrocarbons, could limit or prohibit our ability to utilize hydraulic fracturing or waste water injection control wells.
In addition, concerns have been raised about the potential for seismic activity to occur from the use of underground injection control wells, a predominant method for disposing of waste water from oil and gas activities.  New rules and regulations may be developed to address these concerns, possibly limiting or eliminating the ability to use disposal wells in certain locations and increasing the cost of disposal in others.  We utilize third parties to dispose of waste water associated with our operations.  These third parties may operate injection wells and may be subject to regulatory restrictions relating to seismicity.
Compliance with environmental regulations and permit requirements governing the withdrawal, storage and use of water necessary for hydraulic fracturing of wells or the disposal of water may increase our operating costs or may cause us to delay, curtail or discontinue our exploration and development plans, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

A large portion of our producing properties areremain concentrated in the Appalachian basin, making us vulnerable to risks associated with operating in limited geographic areas.
OurA large portion of our producing properties currently are geographically concentrated in the Appalachian basin in Pennsylvania, West Virginia and West Virginia.Ohio. At December 31, 2019, nearly 100%2021, approximately 73% of our total estimated proved reserves were attributable to properties located in the Appalachian basin. As a result, of this concentration in one primary region, we may be disproportionately exposed to the impact of regional supply and demand factors, delays or interruptions of production from wells in this area caused by governmental regulation, state and local politics, processing or transportation capacity constraints, market limitations, availability of equipment and personnel, water shortages or interruption of the processing or transportation of natural gas, oil or NGLs.
Many of our business operations depend on activities performed by third parties. Changes to availability, costs and performance of personnel, products and services provided by third parties could adversely impact our business and financial condition.
We rely on third-party service providers to perform necessary drilling and completion and other related operations. The ability of third-party service providers to perform such operations will depend on those service providers' ability to compete for and retain qualified personnel as well as their financial condition, economic performance and ability to access capital, which in turn will depend upon the supply and demand for natural gas, oil and NGLs, prevailing economic conditions, and financial, business and other factors. The failure of a third-party service provider to adequately perform operations could delay drilling or completion or reduce production from the property and adversely affect our financial condition and results of operations.
Changes to the ability of our customers to receive our products or meet their financial, performance and other obligations to us could adversely impact our business and financial condition.
In addition to credit risk related to receivables from commodity derivative contracts, our principal exposures to credit risk are through receivables resulting from the sale of our natural gas, oil and NGL production that we market to energy companies, end users and refineries ($903 million as of December 31, 2021). We are also subject to credit risk due to concentration of receivables with several significant customers. The largest purchaser of our products during the year ended December 31, 2021 accounted for approximately 12% of our product revenues. We do not require all of our customers to post collateral. The inability or failure of our significant customers to meet their obligations to us or their insolvency or liquidation may adversely affect our financial condition.
Competition in the oil and natural gas industry is intense, making it more difficult for us to market natural gas, oil and NGLs, to secure trained personnel and appropriate services, to obtain additional properties and to raise capital.
Our cost of operations is highly dependent on third-party services, and competition for these services can be significant, especially in times when commodity prices are rising.  Similarly, we compete for trained, qualified personnel, and in times of lower prices for the commodities we produce, we and other companies with similar production profiles may not be able to attract and retain this talent.  Our ability to acquire and develop reserves in the future will depend on our ability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment for acquiring properties, marketing

natural gas, oil and NGLs and securing trained personnel.  Also, there is substantial competition for capital available for investment in the oil and gas industry.  Certain of our competitors may possess and employ financial, technical and personnel resources greater than ours.  Those companies may be able to pay more for personnel, property and services and to attract capital at lower rates.  This may become more likely if prices for oil and NGLs increase faster than prices for natural gas, as natural gas comprises a greater percentage of our overall production than it does for most of the companies with whom we compete for talent.
We may be unable to dispose of assets on attractive terms, and may be required to retain liabilities for certain matters.
Various factors could materially affect our ability to dispose of assets if and when we decide to do so, including the availability of purchasers willing to purchase the assets at prices acceptable to us, particularly in times of reduced and volatile commodity prices.  Sellers typically retain liabilities for certain matters.  The magnitude of any such retained liability or indemnification obligation may be difficult to quantify at the time of the transaction and ultimately may be material.  Also, as is typical in divestiture transactions, third parties may be unwilling to release us from guarantees or other credit support provided prior to the sale of the divested assets.  As a result, after a sale, we may remain secondarily liable for the obligations guaranteed or supported to the extent that the buyer of the assets fails to perform these obligations.
Changes to applicable U.S. tax laws and regulations could affect our business and future profitability.
New U.S. laws and policy relating to taxes may have an adverse effect on us and our business and future profitability. Further, existing U.S. tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. The current administration has set forth, and Congress is considering, several tax proposals that would make
38

Table of Contents
Index to Financial Statements
significant changes to U.S. federal income tax laws, if enacted. It is unclear whether Congress will enact these proposals or similar changes and, if enacted, how soon any such changes could take effect. The elimination of certain key U.S. federal income tax deductions currently available to oil and natural gas exploration and production companies may be proposed in the future. These changes may include, among other proposals:
repeal of the percentage depletion allowance for natural gas and oil properties;
elimination of current deductions for intangible drilling and development costs; and
extension of the amortization period for certain geological and geophysical expenditures.
The passage of any such proposals, or any similar legislation, could have an adverse effect on our financial position, results of operations and cash flows.
Our ability to use our net operating loss carryforwards and certain other tax attributes will be limited.
At December 31, 2021, we had substantial amounts of net operating loss carryforwards (“NOLs”) and other attributes for U.S. federal and state income tax purposes. Due to the issuance of common stock associated with the Indigo Merger, we incurred a cumulative ownership change under Sections 382 and 383 of the Internal Revenue Code (“Code”), and as such, our NOLs and other attributes prior to the acquisition are subject to an annual limitation under Section 382 of the Code of approximately $48 million. The ownership change and resulting annual limitation will result in the expiration of NOLs or other tax attributes otherwise available. At December 31, 2021, we had approximately $4 billion of federal NOL carryovers, of which approximately $3 billion have an expiration date between 2035 and 2037 and $1 billion have an indefinite carryforward life. We currently estimate that approximately $2 billion of these federal NOLs will expire before they are able to be used. If a subsequent ownership change were to occur as a result of future transactions in our common stock, our use of remaining U.S. tax attributes may be further limited.
We may experience adverse or unforeseen tax consequences due to further developments affecting our deferred tax assets which could significantly affect our results of operations.
Deferred tax assets, including NOLs, represent future savings of taxes that would otherwise be paid in cash.  As discussed above, at December 31, 2021, we had substantial amounts of NOLs for U.S. federal and state income tax purposes.  Our ability to utilize our deferred tax assets is dependent on the amount of future pre-tax income that we are able to generate through our operations or sale of assets and the applicable U.S. federal income tax and foreign tax laws. If management concludes that it is more likely than not that some or all of the benefit from the deferred tax assets will not be realized, a valuation allowance will be recognized in the period that this conclusion is reached.
A cyber incident could result in information theft, data corruption, operational disruption and/or financial loss.
Our business has become increasingly dependent on digital technologies to conduct day-to-day operations, including certain exploration, development and production activities as well as processing of revenues and payments.  We depend on digital technology, including information systems and related infrastructure as well as cloud applications and services, to process and record financial and operating data, analyze seismic and drilling information, conduct reservoir modeling and reserves estimation, communicate with employees and business associates, perform compliance reporting and in many other activities related to our business.  Our vendors, service providers, purchasers of our production and financial institutions are also dependent on digital technology.
As dependence on digital technologies has increased, cyber incidents, including deliberate attacks or unintentional events, have also increased.  Our technologies, systems, networks, and those of our business associates may become the target of cyber-attacks or information security breaches, which could lead to disruptions in critical systems, unauthorized release of confidential or protected information, corruption of data or other disruptions of our business operations.  In addition, certain cyber incidents, such as surveillance, may remain undetected for an extended period.
A cyber-attack involving our information systems and related infrastructure, or that of companies with which we deal, could disrupt our business and negatively impact our operations in a variety of ways, including:
unauthorized access to seismic data, reserves information, strategic information or other sensitive or proprietary information could have a negative impact on our ability to compete for natural gas and oil resources;
unauthorized access to personal identifying information of property lessors, working interest partners, employees and vendors, which could expose us to allegations that we did not sufficiently protect that information;
data corruption or operational disruption of production infrastructure could result in loss of production, or accidental discharge;
39

Table of Contents
Index to Financial Statements
a cyber-attack on a vendor or service provider could result in supply chain disruptions, which could delay or halt our major development projects; and
a cyber-attack on a third party gathering, pipeline or rail service provider could delay or prevent us from marketing our production, resulting in a loss of revenues.
These events could damage our reputation and lead to financial losses from remedial actions, loss of business or potential liability, which could have a material adverse effect on our financial condition, results of operations or cash flows.
To date we have not experienced any material losses or interruptions relating to cyber-attacks; however, there can be no assurance that we will not suffer such losses in the future.  As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any information security vulnerabilities.
Terrorist activities could materially and adversely affect our business and results of operations.
Terrorist attacks and the threat of terrorist attacks, whether domestic or foreign attacks, as well as military or other actions taken in response to these acts, could cause instability in the global financial and energy markets.  Continued hostilities in the Middle East and the occurrence or threat of terrorist attacks in the United States or other countries could adversely affect the global economy in unpredictable ways, including the disruption of energy supplies and markets, increased volatility in commodity prices or the possibility that the infrastructure on which we rely could be a direct target or an indirect casualty of an act of terrorism, and, in turn, could materially and adversely affect our business and results of operations.
The physical impacts of adverse weather may have a negative impact on our business and results of operations.
The physical effects of adverse weather conditions, such as increased frequency and severity of droughts, storms, floods and other climatic events, could adversely affect or delay demand for our products or cause us to incur significant costs in preparing for, or responding to, the effects of climatic events themselves. Potential adverse effects could include disruption of our production activities, including, for example, damages to our facilities from winds or floods, increases in our costs of operation or reductions in the efficiency of our operations, impacts on our personnel, supply chain or distribution chain, as well as potentially increased costs for insurance coverages in the aftermath of such effects. Our ability to mitigate the physical impacts of adverse weather conditions depends in part upon our disaster preparedness and response along with our business continuity planning.
Negative public perception regarding us and/or our industry and increasing attention to ESG matters could have an adverse effect on our business, financial condition and results of operations and damage our reputation.
Negative public perception regarding us and/or our industry resulting from, among other things, concerns raised by advocacy groups about climate change, emissions, hydraulic fracturing, seismicity, oil spills and explosions of transmission lines, may lead to increased litigation risk and regulatory, legislative and judicial scrutiny, which may, in turn, lead to new state and federal safety and environmental laws, regulations, guidelines and enforcement interpretations.  These actions may cause operational delays or restrictions, increased operating costs, additional regulatory burdens and increased risk of litigation.  Moreover, governmental authorities exercise considerable discretion in the timing and scope of permit issuance and the public may engage in the permitting process, including through intervention in the courts.  Negative public perception could cause the permits we need to conduct our operations to be withheld, delayed, or burdened by requirements that restrict our ability to profitably conduct our business. In addition, various officials and candidates at the federal, state and local levels, including some presidential candidates, have proposed banning hydraulic fracturing altogether.
Further, increasing attention to climate change, societal expectations on companies to address climate change, investor and societal expectations regarding voluntary ESG disclosures, generally, and fuel conservation measures, alternative fuel requirements, and increasing consumer demand for alternative forms of energy or energy efficiency initiatives or products may result in increased costs, reduced demand for our products, reduced profits, and negative impacts on our stock price and access to capital markets. Moreover, while we create and publish voluntary disclosures regarding ESG matters from time to time, some of the statements in those voluntary disclosures may be based on hypothetical expectations and assumptions that may or may not be representative of current or actual risks or events or forecasts of expected risks or events, including the costs associated therewith. Such expectations and assumptions are necessarily uncertain and may be prone to error or subject to misinterpretation given the long timelines involved and the lack of an established single approach to identifying, measuring and reporting on many ESG matters. In addition, organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating companies on their approach to ESG matters. Such ratings are used by some investors to inform their investment and voting decisions. Unfavorable ESG ratings could lead to increased negative investor sentiment toward us and our industry and to the diversion of investment to other industries, which could have a negative impact on our stock price and our access to and costs of capital. In addition, failure or a perception (whether or not valid) of failure to implement our

ESG strategy or achieve ESG goals, including any greenhouse gas emission goals, could damage our reputation, causing our investors or consumers to lose confidence in our Company and brands, and negatively impact our operations.
Judicial decisions can affect our rights and obligations.
Our ability to develop gas, oil and NGLs depends on the leases and other mineral rights we acquire and the rights of owners of nearby properties.  We operate in areas where judicial decisions have not yet definitively interpreted various contractual provisions or addressed relevant aspects of property rights, nuisance and other matters that could be the source of claims against us as a developer or operator of properties.  Although we plan our activities according to our expectations of these unresolved areas, based on decisions on similar issues in these jurisdictions and decisions from courts in other states that have addressed them, courts could resolve issues in ways that increase our liabilities or otherwise restrict or add costs to our operations.
Common stockholders will be diluted if additional shares are issued.
We endeavor to create value for our stockholders on a per share basis. From time to time we have issued stock to raise capital for our business or as consideration for acquisitions, including significant offerings of new shares in 2015, 2016, 2020 and 2021.  We also issue restricted stock, options and performance share units to our employees and directors as part of their compensation.  In addition, we may issue additional shares of common stock, additional notes or other securities or debt convertible into common stock, to extend maturities or fund capital expenditures.  If we issue additional shares of our common stock in the future, it may have a dilutive effect on our current outstanding stockholders.
Anti-takeover provisions in our organizational documents and under Delaware law may impede or discourage a takeover, which could cause the market price of our common stock to decline.
We are a Delaware corporation, and the anti-takeover provisions of Delaware law impose various impediments to the ability of a third party to acquire control of us, even if a change in control would be beneficial to our existing stockholders, which, under certain circumstances, could reduce the market price of our common stock.  In addition, protective provisions in our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws or the implementation by our Board of Directors of a stockholder rights plan that could deter a takeover.
Loss of our key executive officers or other personnel, or an inability to attract and retain such officers and personnel, could negatively affect our business.
Our future success depends on the skills, experience and efforts of our key executive officers. The sudden loss of any of these executives’ services or our failure to appropriately plan for any expected key executive succession could materially and adversely affect our business and prospects, as we may not be able to find suitable individuals to replace them on a timely basis, if at all. Additionally, we also depend on our ability to attract and retain qualified personnel to operate and expand our business. Workers may choose to pursue employment with our competitors or in other fields; this competition has become exacerbated by the increase in employee resignations currently taking place throughout the United States. If we fail to attract or retain talented new employees, our business and results of operations could be negatively affected.
The COVID-19 pandemic has negatively affected, and may in the future negatively affect, our business, operating results and financial condition.
COVID-19 has resulted in volatile economic conditions, business and supply chain disruptions and significant volatility and disruption of markets, particularly at the beginning of the pandemic. As a result of COVID-19, we have experienced, and may experience in the future, among other things, a reduction in demand for natural gas, oil, NGLs and other products derived therefrom, and may experience in the future reduced availability of personnel, equipment and services critical to our ability to operate our properties, which could in the future adversely impact, our business, results of operations and overall financial performance. Although several COVID-19 vaccines are currently being widely administered globally, the severity, magnitude and duration of the economic effects of the virus (including any emerging variants) continue to evolve, remain uncertain and may be impacted by various factors beyond our knowledge or control. As such, we might not be able to predict, or respond to, all impacts on a timely basis to prevent near- or long-term adverse impacts on our business, results of operations, financial condition and cash flows. These impacts may be material. Additionally, the impacts of the COVID-19 pandemic could have the effect of heightening many of the other risks described herein.
Risks Related to our Indebtedness and Financing Abilities
A downgrade in our credit rating could negatively impact our cost of and ability to access capital and our liquidity.
Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, could impact our ability to access debt markets in the future to refinance existing debt or obtain

additional funds, affect the market value of our senior notes and increase our borrowing costs.  Such ratings are limited in scope, and do not address all material risks relating to us, but rather reflect only the view of each rating agency of the likelihood we will be able to repay our debt at the time the rating is issued.  An explanation of the significance of each rating may be obtained from the applicable rating agency.  As of February 25, 2022, our long-term issuer ratings were Ba2 by Moody’s, BB+ by Standard and Poor’s and BB by Fitch Investor Services.  There can be no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant.
Actual downgrades in our credit ratings may also impact our interest costs and liquidity.  The interest rates under certain of our senior notes increases as credit ratings fall. Many of our existing commercial contracts contain, and future commercial contracts may contain, provisions permitting the counterparty to require increased security upon the occurrence of a downgrade in our credit rating.  Providing additional security, such as posting letters of credit, could reduce our available cash or our liquidity under our 2018 credit facility for other purposes.  We had $160 million of letters of credit outstanding at December 31, 2021.  The amount of additional financial assurance would depend on the severity of the downgrade from the credit rating agencies, and a downgrade could result in a decrease in our liquidity.
Ourcurrent and future levels of indebtedness may adversely affect our results and limit our growth.
At December 31, 2021, we had total indebtedness of $5.4 billion.  The terms of the indentures governing our outstanding senior notes, our credit facilities, and the lease agreements relating to our drilling rigs, other equipment and headquarters building, which we collectively refer to as our “financing agreements,” impose restrictions on our ability and, in some cases, the ability of our subsidiaries to take a number of actions that we may otherwise desire to take, which may include, without limitation, one or more of the following:
incurring additional debt;
redeeming stock or redeeming certain debt;
making certain investments;
creating liens on our assets; and
selling assets.
The revolving credit facility we entered into in April 2018, as amended (our “2018 credit facility”), contains customary representations, warranties and covenants including, among others, the following covenants:
a prohibition against incurring debt, subject to permitted exceptions;
a restriction on creating liens on assets, subject to permitted exceptions;
restrictions on mergers and asset dispositions;
restrictions on use of proceeds, investments, transactions with affiliates, or change of principal business; and
maintenance of the following financial covenants, commencing with the fiscal quarter ended June 30, 2018:
1.Minimum current ratio of no less than 1.00 to 1.00, whereby current ratio is defined as the Company’s consolidated current assets (including unused commitments under the credit agreement, but excluding non-cash derivative assets) to consolidated current liabilities (excluding non-cash derivative obligations and current maturities of long-term debt).
2.Maximum total net leverage ratio of no greater than 4.00 to 1.00 subsequent to June 30, 2020.  Total net leverage ratio is defined as total debt less cash on hand (up to the lesser of 10% of credit limit or $150 million) divided by consolidated EBITDAX for the last four consecutive quarters.  For purposes of calculating consolidated EBITDAX, the Company can include the Indigo and GEPH consolidated EBITDAX prior to the respective Mergers for the same rolling twelve-month period. EBITDAX, as defined in our 2018 credit facility, excludes the effects of interest expense, depreciation, depletion and amortization, income tax, any non-cash impacts from impairments, certain non-cash hedging activities, stock-based compensation expense, non-cash gains or losses on asset sales, unamortized issuance cost, unamortized debt discount and certain restructuring costs. 
In conjunction with the October 2020 redetermination process, the Company entered into an amendment to the credit agreement governing the 2018 credit facility to, among other matters:
limit the Company's unrestricted cash and cash equivalents to $200 million when loans under the 2018 credit facility are outstanding, subject to certain exceptions; and
42

Table of Contents
Index to Financial Statements
increase the applicable rate by 25 basis points on loans outstanding under the 2018 credit facility.
As of December 31, 2021, we were in compliance with all of the covenants of our 2018 credit facility. Our ability to comply with these financial covenants depends in part on the success of our development program and upon factors beyond our control, such as the market prices for natural gas, oil and NGLs.
Our level of indebtedness and off-balance sheet obligations, and the covenants contained in our financing agreements, could have important consequences for our operations, including:
requiring us to dedicate a substantial portion of our cash flow from operations to required payments, thereby reducing the availability of cash flow for working capital, capital investing and other general business activities;
limiting our ability to obtain additional financing in the future for working capital, capital investing, acquisitions and general corporate and other activities;
limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and
detracting from our ability to successfully withstand a downturn in our business or the economy generally.
Any significant reduction in the borrowing base under our 2018 credit facility may negatively impact our ability to fund our operations, and we may not have sufficient funds to repay borrowings under our 2018 credit facility if required as a result of a borrowing base redetermination.
The amount we may borrow under our 2018 credit facility is capped at the lower of the total of our bank commitments and a “borrowing base” determined from time to time by the lenders based on our reserves, market conditions and other factors.  As of December 31, 2021, the elected borrowing base and total aggregate commitments were $2.0 billion, which was most recently reaffirmed as of October 2021.  The borrowing base is subject to scheduled semiannual and other elective collateral borrowing base redeterminations based on our natural gas, oil and NGL reserves and other factors.  As of December 31, 2021, we had $460 million of outstanding borrowings under our 2018 credit facility, and we expect to borrow under that facility in the future.  As of December 31, 2021, we had $160 million of letters of credit issued under the 2018 credit facility and unused borrowing capacity was approximately $1.4 billion which exceeds our currently modeled needs.  Any significant reduction in our borrowing base as a result of borrowing base redeterminations or otherwise may negatively impact our liquidity and our ability to fund our operations and, as a result, may have a material adverse effect on our financial position, results of operation and cash flow.  Further, if the outstanding borrowings under our 2018 credit facility were to exceed the borrowing base as a result of any such redetermination or other reasons, we would be required to repay the excess within a brief period.  We may not have sufficient funds to make such repayments.  If we do not have sufficient funds and we are otherwise unable to negotiate renewals of our borrowings or arrange new financing, we may have to sell significant assets.  Any such sale could have a material adverse effect on our business and financial results.
Our ability to comply with the covenants and other restrictions in our financing agreements may be affected by events beyond our control, including prevailing economic and financial conditions.
Failure to comply with the covenants and other restrictions could lead to an event of default and the acceleration of our obligations under our senior notes, credit facilities or other financing agreements, and in the case of the lease agreements for drilling rigs, compressors and pressure pumping equipment, loss of use of the equipment.  In particular, the occurrence of risks identified elsewhere in this section, such as declines in commodity prices, increases in basis differentials and inability to access markets, could reduce our profits and thus the cash we have to fulfill our financial obligations.  If we are unable to satisfy our obligations with cash on hand, we could attempt to refinance such debt, sell assets or repay such debt with the proceeds from an equity offering.  We cannot assure that we will be able to generate sufficient cash flow to pay the interest on our debt, to meet our lease obligations, or that future borrowings, equity financings or proceeds from the sale of assets will be available to pay or refinance such debt or obligations.  The terms of our financing agreements may also prohibit us from taking such actions. Factors that will affect our ability to raise cash through an offering of our capital stock, a refinancing of our debt or a sale of assets include financial market conditions and our market value and operating performance at the time of such offering or other financing.  We cannot assure that any such proposed offering, refinancing or sale of assets can be successfully completed or, if completed, that the terms will be favorable to us.
The elimination of LIBOR may adversely affect the cost of our borrowings.
Regulatory authorities in the U.K. ceased publication of certain LIBOR tenors after December 31, 2021 and will cease publication of all USD LIBOR tenors after June 30, 2023. In the U.S., the Alternative Reference Rates Committee has formally recommended forward-looking Secured Overnight Financing Rate (“SOFR”) term rates. We anticipate using a variation of the LIBOR rate until our credit agreement is extended. We do not expect the replacement of LIBOR to result in a material impact to
43

our financial statements; however, negotiations with respect to financing agreements could require us to incur incremental expenses and may subject us to disputes over the appropriateness or comparability of the relevant replacement reference index. In addition, there can be no assurance that the application of SOFR or any other alternative reference rate will not increase our interest expense or will not introduce operational risks in our accounting or financial reporting and other aspects of our business.
Risks Related to Governmental Regulation
Climate change legislation or regulations governing the emissions of greenhouse gases could result in increased operating costs and reduce demand for the natural gas, oil and NGLs we produce, and concern in financial and investment markets over greenhouse gasses and fossil fuel production could adversely affect our access to capital and the price of our common stock.
In response to findings that emissions of carbon dioxide, methane and other greenhouse gases present an endangerment to human health and the environment, the EPA has adopted regulations under existing provisions of the federal Clean Air Act that, among other things, establish Prevention of Significant Deterioration, or PSD, construction and Title V operating permit reviews for certain large stationary sources.  Facilities required to obtain PSD permits for their greenhouse gas emissions also will be required to meet “best available control technology” standards that will be established on a case-by-case basis.  EPA rulemakings related to greenhouse gas emissions could adversely affect our operations and restrict or delay our ability to obtain air permits for new or modified sources.
The EPA also has adopted rules requiring the monitoring and reporting of greenhouse gas emissions from specified onshore and offshore natural gas and oil production sources in the United States on an annual basis, which include certain of our operations. In MayJune 2016, the EPA finalized additional regulations to controlestablishing NSPS, known as Subpart OOOOa, for methane and volatile organic compoundcompounds from new and modified oil and natural gas production and natural gas processing and transmission facilities. In September 2020, the EPA finalized two sets of amendments to the 2016 Subpart OOOOa standards. The first, known as the 2020 Technical Rule, reduced the 2016 rule's fugitive emissions frommonitoring requirements and expanded exceptions to pneumatic pump requirements, among other changes. The second, known as the the 2020 Policy Rule, rescinded the methane-specific requirements for certain oil and natural gas equipmentsources in the production and operations.  However, inprocessing segments. On January 20, 2021, the current administration issued an Executive Order directing the EPA to rescind the 2020 Technical Rule by September 20182021 and August 2019,consider revising the 2020 Policy Rule. On June 30, 2021, the current administration signed a Congressional Review Act (“CRA”) resolution passed by Congress that revoked the 2020 Policy Rule. The CRA resolution did not address the 2020 Technical Rule.
Further, on November 15, 2021, the EPA issued a proposed revisionsrule intended to thosereduce methane emissions from new and existing oil and gas sources. The proposed rule would make the existing regulations which, if finalized,in Subpart OOOOa more stringent and create a Subpart OOOOb to expand reduction requirements for new, modified, and reconstructed oil and gas sources, including standards focusing on certain source types that have never been regulated under the CAA (including intermittent vent pneumatic controllers, associated gas, and liquids unloading facilities). In addition, the proposed rule would establish “Emissions Guidelines,” creating a Subpart OOOOc that would require states to develop plans to reduce certain obligations thereunder.methane emissions from existing sources that must be at least as effective as presumptive standards set by the EPA. Under the proposed rule, states would have three years to develop their compliance plan for existing sources and the regulations for new sources would take effect immediately upon issuance of a final rule. The EPA is expected to issue both a supplemental proposed rule, that may expand or modify the current proposed rule, and final rule by the end of 2022. As a result of these regulatory changes, the scope of any final methane regulations or the costs for complying with federal methane regulations are uncertain.
Although Congress from time to time has considered legislation to reduce emissions of greenhouse gases, there has not been significant activity in the form of adopted legislation to reduce greenhouse gas emissions at the federal level in recent years. However, the United States House of Representatives passed H.R. 5376, known as the Build Back Better Act on November 3, 2021. The House version of the bill targets methane emissions from oil and gas sources by proposing to implement fees for excess methane leaking from wells, storage sites and pipelines as well as fees for new producing and non-producing oil and gas leases and off-shore pipelines. The United States Senate did not pass the House version of the Build Back Better Act, and it is unclear whether any portions of the bill will become law. In the absence of such federal climate legislation, a number of states, including states in which we operate, have enacted or passed measures to track and reduce emissions of greenhouse gases, primarily through the planned development of greenhouse gas emission inventories and regional greenhouse gas cap-and-trade programs. Most of these cap-and-trade programs require major sources of emissions or major producers of fuels to acquire and surrender emission allowances, with the number of allowances available for purchase reduced each year until the overall greenhouse gas emission reduction goal is achieved. These reductions may cause the cost of allowances to escalate significantly over time.
The adoption and implementation of regulations that require reporting of greenhouse gases or otherwise limit emissions of greenhouse gases from our equipment and operations could require us to incur increased operating costs, including costs to monitor and report on greenhouse gas emissions, or install new equipment to reduce emissions of greenhouse gases associated with
44

our operations.operations, acquire emissions allowances or comply with new regulatory requirements. In addition, these regulatory initiatives could drive down demand for our products, by stimulating demand for alternative forms of energy that do not rely on combustion of fossil fuels that serve as a major source of greenhouse gas emissions, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. At the same time,While some new laws and regulations are prompting power producers to shift from coal to natural gas, which is increasing demand.has a positive effect on demand, regulatory incentives or requirements to conserve energy, use alternative sources or reduce greenhouse gas emissions in product supply chains could reduce demand for the products we produce.
In December 2015, over 190 countries, including the United States, reached an agreement to reduce global greenhouse gas emissions (the “Paris Agreement”).emissions. The Paris Agreement entered into force in November 2016 after more than 70 nations, including the United States, ratified or otherwise indicated their intent to be bound by the agreement. In June 2017, President Trump announced that the United States intends to withdraw from the Paris Agreement and to seek negotiations either to reenter the Paris Agreement on different terms or a separate agreement.  In August 2017, the U.S. Department of State officially informed the United Nations of the intent of the United States to withdraw from the Paris Agreement.  In November 2019, the United States formally initiated the process for withdrawing from the Paris Agreement, which would resultwithdrawal became effective in an effective exit date of November 2020. TheHowever, on January 20, 2021, the current administration issued written notification to the United Nations of the United States’ adherenceintention to the exit process and/or the terms on which the United States may re-enterrejoin the Paris Agreement, orwhich became effective on February 19, 2021. In addition, in September 2021, the current administration publicly announced the Global Methane Pledge, a separately negotiated agreement are unclearpact that aims to reduce global methane emissions at this time.least 30% below 2020 levels by 2030. Since its formal launch at the United Nations Climate Change Conference (COP26), over 100 countries have joined the pledge. To the extent that the United States and other countries implement this agreement or impose other climate change regulations on the oil and natural gas industry, or that investors insist on compliance regardless of legal requirements, it could have an adverse effect on our business.
We, our service providers and our customersare subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities.
Our development and production operations and the transportation of our products to market are subject to complex and stringent federal, state and local laws and regulations, including those governing protection of the environment and natural resources, the occupational health and safety aspects of our operations, the discharge of materials into the environment, and the protection of certain plant and animal species.  See “Other – Environmental Regulation” in Item 1 of Part I of this Annual Report for a description of the laws and regulations that affect us.  These laws and regulations require us, our service providers and our customers to obtain and maintain numerous permits, approvals and certificates from various federal, state and local governmental authorities.  Environmental regulations may restrict the types, quantities and concentration of materials that may be released into the environment in connection with drilling and production activities, limit or prohibit drilling or transportation activities on certain lands lying within wilderness, wetlands, archeological sites and other protected areas, and impose substantial liabilities for pollution resulting from our operations and those of our service providers and customers.  Moreover, we or they may experience delays in obtaining or be unable to obtain required permits, including as a result of government shutdowns, which may delay or interrupt our or their operations and limit our growth and revenues.
Failure to comply with laws and regulations can trigger a variety of administrative, civil and criminal enforcement measures, including investigatory actions, the assessment of monetary penalties, the imposition of remedial requirements, or the issuance of orders or judgments limiting or enjoining future operations.  Strict liability or joint and several liability may be imposed under certain laws, which could cause us to become liable for the conduct of others or for consequences of our own actions.  Moreover, our costs of compliance with existing laws could be substantial and may increase or unforeseen liabilities could be imposed if existing laws and regulations are revised or reinterpreted, or if new laws and regulations become applicable to our operations.  If we are not able to recover the increased costs through insurance or increased revenues, our business, financial condition, results of operations and cash flows could be adversely affected.
Risks Related to Financial Markets and Uncertainties
The trading price and volume of our common stock may be volatile, and you could lose a significant portion of your investment.
The market price of the common stock could be volatile, and holders of common stock may not be able to resell their common stock at or above the price at which they acquired such securities due to fluctuations in the market price of common stock. The stock markets in general have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of the common stock. Specific factors that may have a significant effect on the market price for our common stock include:
general economic conditions within the U.S. and internationally, including changes in interest rates;
general market conditions, including fluctuations in commodity prices;
domestic and international economic, legal and regulatory factors unrelated to our performance;
45

changes in oil and natural gas prices;
volatility in the financial markets or other global economic factors, including the impact of COVID-19;
actual or anticipated fluctuations in our and our competitors’ quarterly and annual results;
quarterly variations in the rate of growth of our financial indicators;
our business, operations, results and prospects;
our operating and financial performance;
future mergers and strategic alliances;
market conditions in the energy industry;
changes in government regulation, taxes, legal proceedings or other developments;
shortfalls in our operating results from levels forecasted by securities analysts;
investor sentiment toward the stock of oil and gas companies;
changes in revenue or earnings estimates, or changes in recommendations by equity research analysts;
failure to achieve the perceived benefits of the Mergers, including financial results and anticipated synergies, as rapidly as or to the extent anticipated by financial or industry analysts;
speculation in the press or investment community;
the failure of research analysts to cover our stock;
sales of common stock by us, large shareholders or management, or the perception that such sales may occur;
changes in accounting principles, policies, guidance, interpretations or standards;
announcements concerning us or our competitors;
public reaction to our press releases, other public announcements and filings with the SEC;
strategic actions taken by competitors;
actions taken by our shareholders;
additions or departures of key management personnel;
maintenance of acceptable credit ratings or credit quality; and
the general state of the securities markets.
Additionally, we issued a substantial number of shares in connection with the Indigo Merger and the GEPH Merger. Certain restrictions on the resale by the holders such shares expire on March 1, 2022 and June 30, 2022, respectively. If our existing stockholders sell substantial amounts of our common stock in the public market, or if the public perceives that such sales could occur, this could have an adverse impact on the market price of our common stock, even if there is no relationship between such sales and the performance of our business.
These and other factors may impair the market for the common stock and the ability of investors to sell shares at an attractive price. These factors also could cause the market price and demand for the common stock to fluctuate substantially, which may negatively affect the price and liquidity of the common stock. Many of these factors and conditions are beyond our control.
Securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company’s securities. Such litigation, if instituted against us, could result in very substantial costs, divert management’s attention and resources and harm our business, operating results and financial condition.
Market views of our industry generally can affect our stock price.price, liquidity and ability to obtain financing.
Factors described elsewhere, including views regarding future commodity prices, regulation and climate change, can affect the amount investors choose to invest in our industry generally. Recent years have seen a significant reduction in overall investment in exploration and production companies, resulting in a drop in individual companies’ stock prices. Separate from actual and possible governmental action, certain financial institutions have announced policies to cease investing or to divest investments in companies, such as ours, that produce fossil fuels, and some banks have announced they no longer will lend to

companies in this sector.  To date these represent small fractions of overall sources of equity and debt, but that fraction could grow and thus affect our access to capital.  Moreover, some equity investors are expressing concern over these matters and may prompt companies in our industry to adopt more costly practices even absent governmental action.  Although we believe our
46

practices result in low emission rates for methane and other greenhouse gases as compared to others in our industry, complying with investor sentiment may require modifications to our practices, which could increase our capital and operating expenses.
Volatility in the financial markets or in global economic factors could adversely impact our business and financial condition.
Our business may be negatively impacted by adverse economic conditions or future disruptions in global financial markets. Included among these potential negative impacts are reduced energy demand and lower commodity prices, including due to the possible impact of the coronavirus (COVID-19),COVID-19, increased difficulty in collecting amounts owed to us by our customers, reduced access to credit markets and the risks related to the discontinuation of LIBOR and other reference rates, including increased expenses and litigation and the effectiveness of interest rate hedge strategies.  Our ability to access the capital markets may be restricted at a time when we would like, or need, to raise financing.  If financing is not available when needed, or is available only on unfavorable terms, we may be unable to implement our business plans or otherwise take advantage of business opportunities or respond to competitive pressures.
Any changes in U.S. trade policy could trigger retaliatory actions by affected countries, resulting in “trade wars,” in increased costs for materials necessary for our industry along with other goods imported into the United States, which may reduce customer demand for these products if the parties having to pay those tariffs increase their prices, or in trading partners limiting their trade with the United States.  If these consequences are realized, the volume of economic activity in the United States, including growth in sectors that utilize our products, may be materially reduced along with a reduction in the potential export of our products.  Such a reduction may materially and adversely affect commodity prices, our sales and our business.

Ourproved natural gas, oil and NGL reserves are estimates that include uncertainties.  Any material changes to these uncertainties or underlying assumptions could cause the quantities and net present value of our reserves to be overstated or understated.
As described in more detail under “Critical Accounting Policies and Estimates – Natural Gas and Oil Properties” in Item 7 of Part II of this Annual Report, our reserve data represents the estimates of our reservoir engineers made under the supervision of our management, and our reserve estimates are audited each year by Netherland, Sewell & Associates, Inc., or NSAI, an independent petroleum engineering firm.  Reserve engineering is a subjective process of estimating underground accumulations of natural gas, oil and NGLs that cannot be measured in an exact manner.  The process of estimating quantities of proved reserves is complex and inherently imprecise, and the reserve data included in this document are only estimates.  The process relies on
36

Table of Contents
Index to Financial Statements
interpretations of available geologic, geophysical, engineering and production data.  The extent, quality and reliability of this technical data can vary.  The process also requires certain economic assumptions, some of which are mandated by the SEC, such as using historic natural gas, oil and NGL prices rather than future projections.  Additional assumptions include drilling and operating expenses, capital investing, taxes and availability of funds. Furthermore, different reserve engineers may make different estimates of reserves and cash flows based on the same data.
Results of drilling, testing and production subsequent to the date of an estimate may justify revising the original estimate.  Accordingly, initial reserve estimates often vary from the quantities of natural gas, oil and NGLs that are ultimately recovered, and such variances may be material.  Any significant variance could reduce the estimated quantities and present value of our reserves.
You should not assume that the present value of future net cash flows from our proved reserves is the current market value of our estimated natural gas, oil and NGL reserves.  In accordance with SEC requirements, we base the estimated discounted future net cash flows from our proved reserves on the preceding 12-month average natural gas, oil and NGL index prices, calculated as the unweighted arithmetic average for the first day of the month price for each month and costs in effect on the date of the estimate, holding the prices and costs constant throughout the life of the properties.  Actual future prices and costs may differ materially from those used in the net present value estimate, and future net present value estimates using then current prices and costs may be significantly less than the current estimate.  In addition, the 10% discount factor we use when calculating discounted future net cash flows for reporting requirements in compliance with the applicable accounting standards may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with us or the oil and gas industry in general.Risk
Our commodity price risk management and measurement systems and economic hedging activities might not be effective and could increase the volatility of our results.
We currently seek to hedge the price of a significant portion of our estimated production through swaps, collars, floors and other derivative instruments.  The systems we use to quantify commodity price risk associated with our businesses might not always be effective.  Further, such systems do not in themselves manage risk, particularly risks outside of our control, and adverse changes in energy commodity market prices, volatility, adverse correlation of commodity prices, the liquidity of markets, changes in interest rates and other risks discussed in this report might still adversely affect our earnings, cash flows and balance sheet under applicable accounting rules, even if risks have been identified.  Furthermore, no single hedging arrangement can adequately address all risks present in a given contract.  For example, a forward contract that would be effective in hedging commodity price volatility risks would not hedge the contract’s counterparty credit or performance risk.  Therefore, unhedged risks will always continue to exist.
Our use of derivatives, through which we attempt to reduce the economic risk of our participation in commodity markets could result in increased volatility of our reported results.  Changes in the fair values (gains and losses) of derivatives that qualify as hedges under GAAP to the extent that such hedges are not fully effective in offsetting changes to the value of the hedged commodity, as well as changes in the fair value of derivatives that do not qualify or have not been designated as hedges under GAAP, must be recorded in our income.  This creates the risk of volatility in earnings even if no economic impact to us has occurred during the applicable period.  To the extent we cap or lock prices at specific levels, we would also forgo the ability to realize the higher revenues that would be realized should prices increase.
The impact of changes in market prices for natural gas, oil and NGLs on the average prices paid or received by us may be reduced based on the level of our hedging activities.  These hedging arrangements may limit or enhance our margins if the market prices for oil, natural gas or NGLs were to change substantially from the price established by the hedges.  In addition, our hedging arrangements expose us to the risk of financial loss if our production volumes are less than expected.
We may be unable to dispose of assets on attractive terms, and may be required to retain liabilities for certain matters.
Various factors could materially affect our ability to dispose of assets if and when we decide to do so, including the availability of purchasers willing to purchase the assets at prices acceptable to us, particularly in times of reduced and volatile commodity prices.  Sellers typically retain liabilities for certain matters.  The magnitude of any such retained liability or indemnification obligation may be difficult to quantify at the time of the transaction and ultimately may be material.  Also, as is typical in divestiture transactions, third parties may be unwilling to release us from guarantees or other credit support provided prior to the sale of the divested assets.  As a result, after a sale, we may remain secondarily liable for the obligations guaranteed or supported to the extent that the buyer of the assets fails to perform these obligations.

The implementation of derivatives legislation could have an adverse effect on our ability to use derivative instruments to reduce the effect of commodity price, interest rate and other risks associated with our business.
The Dodd-Frank Act established federal oversight and regulation of the over-the-counter derivatives market and entities, including us, which participate in that market.  The Dodd-Frank Act requires the CFTC, the SEC, and other regulatory authorities to promulgate rules and regulations implementing the Dodd-Frank Act.  Although the CFTC has finalized most of its regulations under the Dodd-Frank Act, it continues to review and refine its initial rulemakings through additional interpretations and supplemental rulemakings.  As a result, it is not possible at this time to predict the ultimate effect of the rules and regulations on our business and while most of the regulations have been adopted, any new regulations or modifications to existing regulations may increase the cost of derivative contracts, limit the availability of derivatives to protect against risks that we encounter, reduce our ability to monetize or restructure our existing derivative contracts, and increase our exposure to less creditworthy counterparties.  If we reduce our use of derivatives as a result of the Dodd-Frank Act and the regulations thereunder, our results of
47

operations may become more volatile and our cash flows may be less predictable, which could adversely affect our ability to plan for and fund capital investing.
In January 2020, the CFTC proposed new amended regulations that would place federal limits on positions in certain core futures and equivalent swaps contracts for or linked to certain physical commodities, subject to exceptions for certain bona fide hedging transactions. These rules were finalized in January of 2021 with compliance dates as early as January 1, 2022 for certain positions. In 2016, the CFTC finalized a companion rule on aggregation of positions among entities under common ownership or control.  If finalized,It is too early to determine the position limits ruleprecise effect of these rules on our business, but they may have an impact on our ability to hedge our exposure to certain enumerated commodities.commodities (whether using futures contracts, over-the-counter derivatives contracts or otherwise).
The CFTC has designated certain interest rate swaps and credit default swaps for mandatory clearing and mandatory trading on designated contract markets or swap execution facilities.  The CFTC may designate additional classes of swaps as subject to the mandatory clearing requirement in the future, but has not yet proposed rules designating any other classes of swaps, including physical commodity swaps, for mandatory clearing.  The CFTC and prudential banking regulators also adopted mandatory margin requirements on uncleared swaps between swap dealers and certain other counterparties.  The margin requirements are currently effective with respect to certain market participants and will be phased in over time with respect to other market participants, based on the level of an entity’s swaps activity.  We expect to qualify for and rely upon an end-user exception from the mandatory clearing and trade execution requirements for swaps entered to hedge our commercial risks.  We also should qualify for an exception from the uncleared swaps margin requirements.  However, the application of the mandatory clearing and trade execution requirements and the uncleared swaps margin requirement to other market participants, such as swap dealers, may adversely affect the cost and availability of the swaps that we use for hedging.
Further regulations relatingRisks Related to and interpretations of the Tax Cuts and Jobs Act may have a material impact on our financial condition and results of operations.
Significant tax reform legislation in 2017 (commonly referred to as the “Tax Cuts and Jobs Act,” or the “Tax Reform Act”), brought major changes to corporate taxation, including a permanent reduction of the corporate income tax rate, a partial limitation on the deductibility of business interest expense, limitation of the deduction for certain net operating losses to 80% of current year taxable income for tax years 2018 and beyond, an indefinite net operating loss carryforward, immediate deductions for certain new investments instead of deductions for depreciation expense over timeIndigo Merger and the modification or repeal of many business deductions and credits.  The Treasury Department and the Internal Revenue Service continue to release regulations relating to and interpretive guidance of the legislation contained in the Tax Reform Act.  Any significant variance of our current interpretation of such legislation from any future regulations or interpretive guidance could result in a change to the presentation of our financial condition and results of operations and could negatively affect our business.
Certain U.S. federal income tax deductions currently available with respect to oil and natural gas exploration and production may be eliminated as a result of future legislation.
The elimination of certain key U.S. federal income tax deductions currently available to oil and natural gas exploration and production companies may be proposed in the future.  These changes may include, among other proposals:
repeal of the percentage depletion allowance for natural gas and oil properties;
elimination of current deductions for intangible drilling and development costs;
elimination of the deduction for certain domestic production activities; and
extension of the amortization period for certain geological and geophysical expenditures.

The passage of these or any similar changes in U.S. federal income tax laws to eliminate or postpone certain tax deductions that are currently available with respect to oil and natural gas exploration and development could have an adverse effect on our financial position, results of operations and cash flows.GEPH Merger
We may experience adverse or unforeseen tax consequences due to further developments affecting our deferred tax assets that could significantly affect our results.
Deferred tax assets, including net operating loss carryforwards, represent future savings of taxes that would otherwise be paid in cash.  At December 31, 2019, we had substantial amounts of net operating loss carryforwards for U.S. federal and state income tax purposes.  Our ability to utilizenot achieve the deferred tax assets is dependent on the amount of future pre-tax income that we are able to generate through our operations or sale of assets. If management concludes that it is more likely than not that some or allanticipated benefits of the benefit fromIndigo Merger and the deferred tax asset will not be realized, a valuation allowance will be recognized inGEPH Merger, and the period that this conclusion is reached. In addition, limitationsIndigo Merger and the GEPH Merger may exist upon use of these carryforwards in the event that a change in controldisrupt our current plans or operations.
The success of the Company occurs.
A cyber incident could resultIndigo Merger and the GEPH Merger will depend, in information theft, data corruption, operational disruption and/or financial loss.
Our business has become increasingly dependent on digital technologies to conduct day-to-day operations, including certain exploration, development and production activities as well as processing of revenues and payments.  We depend on digital technology, including information systems and related infrastructure as well as cloud applications and services, to process and record financial and operating data, analyze seismic and drilling information, conduct reservoir modeling and reserves estimation, communicate with employees and business associates, perform compliance reporting and in many other activities related to our business.  Our vendors, service providers, purchasers of our production and financial institutions are also dependent on digital technology.
As dependence on digital technologies has increased, cyber incidents, including deliberate attacks or unintentional events, have also increased.  Our technologies, systems, networks, and those of our business associates may become the target of cyber-attacks or information security breaches, which could lead to disruptions in critical systems, unauthorized release of confidential or protected information, corruption of data or other disruptions of our business operations.  In addition, certain cyber incidents, such as surveillance, may remain undetected for an extended period.
A cyber-attack involving our information systems and related infrastructure, or that of companies with which we deal, could disrupt our business and negatively impact our operations in a variety of ways, including:
unauthorized access to seismic data, reserves information, strategic information or other sensitive or proprietary information could have a negative impactpart, on our ability to compete for natural gasrealize the anticipated benefits and oil resources;
unauthorized access to personal identifying informationcost savings from combining our business and the businesses of property lessors, working interest partners, employeesIndigo and vendors, which could expose us to allegations that we did not sufficiently protect that information;
data corruption or operational disruption of production infrastructure could result in loss of production, or accidental discharge;
a cyber-attack on a vendor or service provider could result in supply chain disruptions, which could delay or halt our major development projects;GEPH, and
a cyber-attack on a third party gathering, pipeline or rail service provider could delay or prevent us from marketing our production, resulting in a loss of revenues.
These events could damage our reputation and lead to financial losses from remedial actions, loss of business or potential liability, which could have a material adverse effect on our financial condition, results of operations or cash flows.
To date we have not experienced any material losses or interruptions relating to cyber-attacks; however, there can be no assurance that we will not sufferbe able to successfully integrate such lossesbusinesses or otherwise realize the anticipated benefits of the Indigo Merger and the GEPH Merger. Difficulties in integrating such businesses may result in the future.  As cyber threats continuecombined company performing differently than expected, in operational challenges, or in the failure to evolve, werealize anticipated expense-related efficiencies. Potential difficulties that may be requiredencountered in the integration process include, among others:
the inability to expend significant additional resources to continue to modify or enhance our protective measures or to investigatesuccessfully integrate such businesses in a manner that permits the achievement of full revenue, expected cash flows and remediate any information security vulnerabilities.
Terrorist activities could materially and adversely affect our business and results of operations.

the disruption of, energy supplies and markets, increased volatility in commodity prices or the possibility that the infrastructure on which we rely could be a direct target or an indirect casualtyloss of an act of terrorism, and, in turn, could materially and adversely affect our business and results of operations.
Negative public perception regarding us and/or our industry could have an adverse effect on our operations.
Negative public perception regarding us and/or our industry resulting from, among other things, concerns raised by advocacy groups about climate change, emissions, hydraulic fracturing, seismicity, oil spills and explosions of transmission lines, may lead to regulatory scrutiny, which may, in turn, lead to new state and federal safety and environmental laws, regulations, guidelines and enforcement interpretations.  These actions may cause operational delays or restrictions, increased operating costs, additional regulatory burdens and increased risk of litigation.  Moreover, governmental authorities exercise considerable discretion in the timing and scope of permit issuance and the public may engage in the permitting process, including through intervention in the courts.  Negative public perception could cause the permits we need to conduct our operations to be withheld, delayed, or burdened by requirements that restrict our ability to profitably conduct our business. In addition, various officials and candidates at the federal, state and local levels, including some presidential candidates, have proposed banning hydraulic fracturing altogether.
Judicial decisions can affect our rights and obligations.
Our ability to develop gas, oil and NGLs depends on the leases and other mineral rights we acquire and the rights of owners of nearby properties.  We operate in areas where judicial decisions have not yet definitively interpreted various contractual provisions or addressed relevant aspects of property rights, nuisance and other matters that could be the source of claims against us as a developer or operator of properties.  Although we plan our activities according to our expectations of these unresolved areas, based on decisions on similar issues in these jurisdictions and decisions from courts in other states that have addressed them, courts could resolve issues in ways that increase our liabilities or otherwise restrict or add costs to our operations.
Common stockholders will be diluted if additional shares are issued.
From time to time we have issued stock to raise capital for our business, including significant offerings of new shares in 2015 and 2016.  We also issue restricted stock, options and performance share units to our employees and directors as part of their compensation.  In addition, we may issue additional shares of common stock, additional notes or other securities or debt convertible into common stock, to extend maturities or fund capital expenditures.  If we issue additional shares of our common stock in the future, it may have a dilutive effect on our current outstanding stockholders.

We are a Delaware corporation, and the anti-takeover provisions of Delaware law impose various impediments to the ability of a third party to acquire control of us, even if a change in control would be beneficial to our existing stockholders, which, under certain circumstances, could reduce the market price of our common stock.  In addition, protective provisions in our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws or the implementation by our Board of Directors of a stockholder rights plan that could deter a takeover.policies.

During 2019,2021, we were required to file Form 23, “Annual Survey of Domestic Oil and Gas Reserves,” with the U.S. Department of Energy.  The basis for reporting reserves on Form 23 is not comparable to the reserve data included in “Supplemental Oil and Gas Disclosures” in Item 8 of Part II of this Annual Report.  The primary differences are that Form 23 reports gross reserves, including the royalty owners’ share, and includes reserves for only those properties of which we are the operator.
Title to Properties
We believe that we have satisfactory title to substantially all of our active properties in accordance with standards generally accepted in the oil and natural gas industry.  Our properties are subject to customary royalty and overriding royalty interests, certain contracts relating to the exploration, development, operation and marketing of production from such properties, consents to assignment and preferential purchase rights, liens for current taxes, applicable laws and other burdens, encumbrances and irregularities in title, which we believe do not materially interfere with the use of or affect the value of such properties.  Prior to acquiring undeveloped properties, we endeavor to perform a title investigation that is thorough but less vigorous than that we endeavor to conduct prior to drilling, which is consistent with standard practice in the oil and natural gas industry.  Generally, before we commence drilling operations on properties that we operate, we conduct a title examination and perform curative work with respect to significant defects that we identify.  We believe that we have performed title review with respect to substantially all of our active properties that we operate.
ITEM 3.  LEGAL PROCEEDINGS 
We are subject to various litigation, claims and proceedings that arise in the ordinary course of business, such as for alleged breaches of contract, miscalculation of royalties, employment matters, traffic incidents, pollution, contamination, encroachment on others’ property or nuisance.  We accrue for such items when a liability is both probable and the amount can be reasonably estimated.  It is not possible at this time to estimate the amount of any additional loss, or range of loss that is reasonably possible, but based on the nature of the claims, management believes that current litigation, claims and proceedings, individually or in aggregate and after taking into account insurance, are not likely to have a material adverse impact on our financial position, results of operations or cash flows, for the period in which the effect of that outcome becomes reasonably estimable.  Many of these matters are in early stages, so the allegations and the damage theories have not been fully developed, and are all subject to inherent uncertainties; therefore, management’s view may change in the future.  If an unfavorable final outcome were to occur, there exists the possibility of a material impact on our financial position, results of operations or cash flows for the period in which the effect becomes reasonably estimable. 
We are also subject to laws and regulations relating to the protection of the environment.  Environmental and cleanup related costs of a non-capital nature are accrued when it is both probable that a liability has been incurred and when the amount can be reasonably estimated.  Management believes any future remediation or other compliance related costs will not have a material effect on our financial position or results of operations.

ITEM 4.  MINE SAFETY DISCLOSURES
Our sand mining facility in Arkansas, which previously supported our Fayetteville Shale operations, is subject to regulation by the Federal Mine Safety and Health Administration under the Federal Mine Safety and Health Act of 1977.  Information concerning mine safety violations or other regulatory matters required by section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95.1 to this Annual Report. On February 10, 2021, we sold our sand mine to a third party and, as a result, no longer own or operate any mines.

OVERVIEW
Background
Southwestern Energy Company (including its subsidiaries, collectively, “we,” “our,” “us,” “the Company” or “Southwestern”) isWe are an independent energy company engaged in natural gas, oil and NGLs exploration, development and production, which we refer to as “E&P.”  We are also focused on creating and capturing additional value through our marketing business, which we call “Marketing” but previously referred to as “Midstream” when it included the operations of gathering systems..  We conduct most of our businesses through subsidiaries, and we currently operate exclusively in the Appalachian and Haynesville natural gas basins in the lower 48 United States. Our historical financial and operating results include the Fayetteville Shale E&P and related midstream gathering businesses which were sold in early December 2018.
E&P.  Our primary business is the exploration for and production of natural gas oilas well as associated NGLs and NGLs,oil, with our ongoing operations focused on the development of unconventional natural gas reservoirs located in Pennsylvania, West Virginia, Ohio and West Virginia.Louisiana.  Our operations in northeast Pennsylvania, West Virginia and Ohio, which we refer to as “Northeast Appalachia,” are primarily focused on the unconventional natural gas reservoir known as the Marcellus Shale.  Our operations in West Virginia and southwest Pennsylvania, which we refer to as “Southwest Appalachia,“Appalachia,” are focused on the Marcellus Shale, the Utica and the Upper Devonian unconventional natural gas and oilliquids reservoirs.  Collectively, our propertiesOur operations in Pennsylvania and West Virginia are herein referredLouisiana, which we refer to as “Appalachia.“Haynesville, are primarily focused on the Haynesville and Bossier natural gas reservoirs. We also have drilling rigs located in PennsylvaniaAppalachia and West Virginia,Haynesville, and we provide certain oilfield products and services, principally serving our E&P operations thoughthrough vertical integration. In just over a year, we have completed three strategic acquisitions which have added scale to our operations and have laid the foundation for our future:
On November 13, 2020, we closed on the Montage Merger, which increased our footprint in West Virginia and Pennsylvania and expanded our operations into Ohio.
On September 1, 2021, we closed on the Indigo Merger, which established our natural gas operations in the Haynesville and Bossier Shales in Louisiana.
On December 31, 2021, we closed on the GEPH Merger, which expanded our operations in the Haynesville.
The Indigo Merger and GEPH Merger are the result of our strategy to diversify our operations by expanding our portfolio beyond Appalachia into the Haynesville and Bossier formations, giving us additional exposure to the LNG corridor and other markets on the U.S. Gulf Coast. This expansion lowered our enterprise business risk, expanded our economic inventory, opportunity set and business optionality and enabled immediate cost structure savings. See Note 2 to the consolidated financial statements of this Annual Report for more information on the Mergers.
Marketing.  Our marketing activities capture opportunities that arise through the marketing and transportation of natural gas, oil, and NGLs primarily produced in our E&P operations. In December 2018, we divested almost all of our midstream gathering assets as part of the Fayetteville Shale sale.
Focus in 2019.2021. In 2019,We took several steps in late 2020 and throughout 2021 towards achieving our strategic objectives of increasing scale in our operations, improving our margins, generating free cash flow and reducing our debt leverage metrics. We began the year having completed our first strategic business merger with the acquisition of Montage, which expanded our natural gas and liquids production footprint in Appalachia. During 2021, we completed two additional strategic mergers with the acquisitions of Indigo and GEPH, which diversified our asset portfolio into the Haynesville and Bossier formations of Louisiana with access to the LNG corridor and other U.S. Gulf Coast markets. Recovering commodity prices during 2021 along with the increase in production volumes primarily associated with the Mergers, combined with our continued capital discipline to invest at levels which are designed to maintain our daily production consistent with the end of the prior year, have accelerated the generation of free cash flow. Through our disciplined capital investing, the Mergers have already had, and are expected to continue to have, a positive impact on our business and financial results by producing free cash flow, which we expect to use to pay down debt, resulting in the strengthening of our balance sheet and improvement in our debt leverage metrics.

During 2021, we were also able to successfully finance the Indigo Merger and the GEPH Merger while also reducing our revolver balance and re-financing and extending our debt maturities on a large portion of our near-term senior notes at more favorable interest rates. These financings lowered our overall cost of debt and extended our weighted-average time to maturity.
Generating free cash flow is an important part of our strategy to reposition the Company through portfolio optimization, balance sheet management and leveraging our technical, commercial and operational expertise to improve margins.   We continued our strategic shift towards prioritizing the development of our high-value, liquids-rich Southwest Appalachia assets over our pure natural gas assets.  We strengthenedstrengthen our balance sheet, through an additional debt reduction of $80 million (net) and by amending our revolving credit facilitylong-term goal is to extend the maturityincorporate a cash return component into 2024, which improvedour overall economic return for shareholders. Our near-term strategic goal is to utilize our free cash flow to reduce our debt, maturity profile while preservingthereby improving our leverage metrics and financial strength. As we approach our target leverage ratio and operational flexibility.  We made further technological advances in drilling longer laterals with increased precision and completion optimization that enhanced well productivity and significantly reducedtotal debt ranges, we intend to expand our well costs on a per lateral foot basis, resulting in improved returns. In addition, we focused on identifying and implementing opportunitiesuses of free cash flow to lower our overall cost structure.  We addedinclude the return of capital to our shareholders. Free cash flow is a non-GAAP financial measure. We define free cash flow as net cash provided by operating activities, adjusted for (i) changes in assets and liabilities and (ii) cash transaction costs associated with mergers and restructuring, less capital investments. Free cash flow is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We believe free cash flow can provide an indicator of excess cash flow available to a company for the repayment of debt or for other general corporate purposes, as it disregards the timing of settlements of operating assets and liabilities.
Natural gas, oil and NGL price fluctuations present challenges to our industry and our Company, as do changes in laws, regulations and investor sentiment and other key factors described under “Risk Factors” in Item 1A of this Annual Report. Although we currently expect to maintain a rolling three-year derivative portfolio, limitingthere can be no assurance that we will be able to add derivative positions to cover our expected production at favorable prices. See “Quantitative and Qualitative Disclosures About Market Risk” in Item 7A and Note 6 - Derivatives and Risk Management, in the impact of price volatility on approximately 604 Bcfe and 307 Bcfe of our forecasted 2020 and 2021 production, respectively, through the use of commodity derivatives. consolidated financial statements included in this Annual Report for further details.

Outlook
We expectOur primary focus in 2022 is to continuemaintain our production profile and improve the safety and efficiency of our operations to exercise capital discipline inoptimize our 2020 capital investment program by investing withinability to generate free cash flow from operations, net of changes in working capital, supplemented by earmarked proceeds of the Fayetteville Shale sale thatand further strengthen our balance sheet.
As we develop our core positions in the meantime have been usedAppalachian and Haynesville natural gas basins in the U.S., we will concentrate on:
Creating Value. We seek to reduce debt. create value for our stakeholders by allocating capital that is focused on earning economic returns; delivering free cash flow; upgrading the quality, depth and capital efficiency of our drilling inventory; and converting resources to proved reserves.
Financial Strength. We intend to protect our financial strength by lowering our leverage ratio and total debt; extending the weighted average years to maturity of our debt; lowering our cost of debt; deploying hedges to protect against downward price movement; covering our costs and meeting other financial commitments; and maintaining a strong liquidity position.
Focus on Execution. We are focused on operating effectively and efficiently with HSE and ESG as core values; building on our data analytics, operating execution, strategic sourcing, vertical integration and large-scale asset development expertise; further enhancing well performance, optimizing well costs and reducing base production declines; growing margins and securing flow assurance through commercial and marketing arrangements.
Capturing the Tangible Benefits of Scale. We strive to create a competitive advantage through strategic transactions that we believe will enhance enterprise returns and deliver financial synergies and operational economies. We believe these transactions lower the risk of our business, expand our opportunity set, increase business optionality and build upon our demonstrated record of asset integration.
We remain committed to achieving these objectives while maintaining our focus on optimizing our portfolio by concentrating our efforts on our highest return investment opportunities, looking for wayscommitment to optimize our cost structure and to maximize margins in each core area of our business and further developing our knowledge of our asset base.being environmentally conscious. We believe that we and our industry will continue to face challenges due to evolving environmental standards by both regulators and investors, the uncertainty of natural gas, oil and NGL prices in the United States, changes in laws, regulations and investor sentiment, and other key factors described above under “RiskRisk Factors. As such, we intend to protect our financial strength by reducing our debt while continuing to extend the weighted average years to maturity of our debt, and by maintaining a derivative program designed to reduce our exposure to commodity price volatility.
COVID-19
During 2021, we did not experience any material impact to our ability to operate or market our production due to the direct or indirect impacts of the COVID-19 pandemic, and we continue to monitor its impact on all aspects of our business. The COVID-19 outbreak resulted in state and local governments implementing measures with various levels of stringency to help control the spread of the virus. The U.S. Department of Homeland Security classifies individuals engaged in and supporting exploration for and production of natural gas, oil and NGLs as “essential critical infrastructure workforce,” and to date, state and local governments have followed this guidance and exempted these activities from business closures. Should this situation change, our access to supplies or workers to drill, complete and operate wells could be materially and adversely affected.
Ensuring the health and welfare of our employees, and all who visit our sites, is our top priority, and we are following all U.S. Centers for Disease Control and Prevention and state and local health department guidelines. Further, we implemented infection control measures at all our sites and put in place travel and in-person meeting restrictions and other physical distancing measures. The degree to which the COVID-19 pandemic or any other public health crisis adversely impacts our operations will depend on future developments, which are uncertain and cannot be predicted, including, but not limited to, the duration and spread of the

outbreak, its severity, the effectiveness of the vaccines and the actions to contain the virus or treat its impact, its impact on the economy and market conditions, and how quickly and to what extent normal economic and operating conditions can resume. We will continually monitor our capital investment program to take into account these changed conditions and proactively adjust our activities and plans. Therefore, while this continued matter could potentially disrupt our operations, the degree of the potentially adverse financial impact cannot be reasonably estimated at this time.
RESULTS OF OPERATIONS
The following discussion of our results of operations for our segments is presented before intersegment eliminations. We report onevaluate our segments as if they were stand-alone operations and accordingly discuss their results prior to any intersegment eliminations.  Restructuring charges, interestInterest expense, gain (loss) on derivatives, gain (loss) on early extinguishment of debt and income taxes are discussed on a consolidated basis.

Commodity Prices
The price we expect to receive for our production is a critical factor in determining the capital investments we make to develop our properties.  Commodity prices fluctuate due to a variety of factors we cannotcan neither control ornor predict, including increased supplies of natural gas, oil or NGLs due to greater exploration and development activities, weather conditions, political and economic events such as the response to the COVID-19 pandemic, and competition from other energy sources.  These factors

impact supply and demand, which in turn determine the sales prices for our production.  In addition to these factors, the prices we realize for our production are affected by our hedgingderivative activities as well as locational differences in market prices, including basis differentials.  We will continue to evaluate the commodity price environments and adjust the pace of our activitiesactivity in order to maintain appropriate liquidity and financial flexibility.

Taxes, Other than Income TaxesMerger-Related Expenses
Taxes other than income taxes per Mcfe may vary from period to period due to changesBeginning with the Montage Merger in ad valoremNovember 2020, we have focused on building scale and severance taxes that result from the mix of our production volumes and fluctuations in commodity prices.  Taxes, other than income taxes, per Mcfe decreased $0.01 per Mcfe for the year ended December 31, 2019, compared to the same period in 2018, primarily due to a $7 million severance tax refund/credit received in the fourth quarter of 2019 related to additional favorable assessments on deductible expenses in Southwest Appalachia and lower realized commodity pricing in 2019. In 2018, we received an $8 million severance tax refund related to a favorable assessment on deductible expenses in Southwest Appalachia which reduced our average severance tax rate applied in 2019.
Full Cost Pool Amortization
Our full cost pool amortization rate increased $0.05 per Mcfe for the year ended December 31, 2019, as compared to 2018.  The increase in the average amortization rate resulted primarily asgeographic diversification throughout 2021. As a result of the impact of capital investmentsthis strategy, we merged with Indigo in September 2021 and the further evaluation of our unproved properties during the year and the impact of the Fayetteville Shale sale, which reduced our total natural gas reserves along with the carrying value of our full cost pool assets.
The amortization rate is impacted by the timing and amount of reserve additions and the future development costs associated with those additions, revisions of previous reserve estimates due to both price and well performance, write-downs that result from non-cash full cost ceiling impairments, proceeds from the sale of properties that reduce the full cost pool, and the levels of costs subject to amortization.  We cannot predict our future full cost pool amortization rate with accuracy due to the variability of each of the factors discussed above, as well as other factors, including but not limited to the uncertainty of the amount of future reserve changes.
Unevaluated costs excluded from amortization were $1.5 billion atGEPH on December 31, 2019 compared to $1.8 billion at December 31, 2018.2021. The unevaluated costs excluded from amortization decreased, as compared to 2018, as the evaluation of previously unevaluated properties totaling $507 million in 2019 was only partially offset by the impact of $258 million of unevaluated capital invested during the same period.
See “Supplemental Oil and Gas Disclosures” in Item 8 of Part II of this Annual Report for additional information regarding our unevaluated costs excluded from amortization.
Impairments
During the year ended December 31, 2019, we recognized non-cash impairments of $13 million associated with non-core E&P assets.
In accordance with accounting guidance for Property, Plant and Equipment, assets held for sale are measured at the lower of carrying value or fair value less costs to sell.  Because the assets outside the full cost pool associated with the Fayetteville Shale sale met the criteria for held for sale accounting in the third quarter of 2018, we determined the carrying value of certain non-full cost pool E&P assets exceeded the fair value less costs to sell.  As a result, a non-cash impairment charge of $15 million was recorded during the year ended December 31, 2018.

In February 2021, employees were notified of a workforce reduction plan as part of an ongoing strategic effort to reposition our portfolio, optimize operational performance and improve margins. Affected employees were offered a severance package, which included a one-time payment depending on length of service and, if applicable, the current value of unvested long-term incentive awards that were forfeited. These costs were recognized as restructuring charges for the year ended December 31, 2021, and were substantially complete by the end of the first quarter of 2021.

See Note 3 of the consolidated financial statements included in this Annual Report for additional details about our restructuring charges.
Taxes, Other than Income Taxes
Taxes other than income taxes per Mcfe may vary from period to period due to changes in ad valorem and severance taxes that result from the mix of our production volumes and fluctuations in commodity prices.  Taxes, other than income taxes, per Mcfe increased $0.05 per Mcfe for the year ended December 31, 2018.
In December 2018, we closed2021, compared to the salesame period in 2020, primarily due to the impact of higher commodity pricing on our severance taxes in West Virginia, which are calculated as a fixed percentage of revenue net of allowable production expenses, and the equity in certainimpact of incremental severance and ad valorem taxes associated with our subsidiaries that owned and operated our Fayetteville Shale E&P and related midstream gatheringacquired assets in Arkansas.  As part of this transaction, most employees associated with those assets became employees of the buyer, although the employment of some was terminated.  All affected employees were offered a severance package, which included a one-time cash payment depending on length of service and, if applicable, the current value of a portion of equity awards that were forfeited.  We incurred $12 million in severance costs related to the Fayetteville Shale saleLouisiana.
Full Cost Pool Amortization
Our full cost pool amortization rate increased $0.04 per Mcfe for the year ended December 31, 2018 and have recognized these costs2021, as restructuring charges.
Ascompared to 2020.  The average amortization rate increased primarily as a result of the Fayetteville Shaleimpact of our acquisitions of natural gas and oil properties in Appalachia and the Haynesville.
The amortization rate is impacted by the timing and amount of reserve additions and the future development costs associated with those additions, revisions of previous reserve estimates due to both price and well performance, write-downs that result from non-cash full cost ceiling impairments, proceeds from the sale during 2018, we incurred $4of properties that reduce the full cost pool, and the levels of costs subject to amortization.  We cannot predict our future full cost pool amortization rate with accuracy due to the variability of each of the factors discussed above, as well as other factors, including but not limited to the uncertainty of the amount of future reserve changes.
Unevaluated costs excluded from amortization were $2,231 million at December 31, 2021 compared to $1,472 million at December 31, 2020.  The unevaluated costs excluded from amortization increased by $759 million, as compared to 2020, as the evaluation of previously unevaluated properties totaling $532 million in charges primarily2021 was more than offset by the impact of $1,291 million of unevaluated capital invested. Of the total increase, $743 million related to office consolidationthe Haynesville properties acquired during 2021.
No impairment expense was recorded in 2020 or 2021 in relation to our natural gas and recognizedoil properties acquired from Montage. These properties were recorded at fair value as of November 13, 2020, in accordance with ASC Topic 820 – Fair Value Measurement. In the fourth quarter of 2020, pursuant to SEC guidance, we determined that the fair value of the properties acquired at the closing of the Montage Merger clearly exceeded the related full-cost ceiling limitation beyond a reasonable doubt and received a waiver from the SEC to exclude the properties acquired in the Montage Merger from the ceiling test calculation. This waiver was granted for all reporting periods through and including the quarter ending September 30, 2021, as long as we could continue to demonstrate that the fair value of properties acquired clearly exceeded the full cost ceiling limitation beyond a reasonable doubt in each reporting period. As part of the waiver received from the SEC, we were required to disclose what the full cost ceiling test impairment amounts for all periods presented in each applicable quarterly and annual filing would have been if the waiver had not been granted. The fair value of the properties acquired in the Montage Merger was based on future commodity market pricing for natural gas and oil pricing existing at the date of the Montage Merger, and we affirmed that there has not been a material decline to the fair value of these costs as restructuring chargesacquired assets since the Montage Merger. The properties acquired in the Montage Merger had an unamortized cost at December 31, 2020 of $1,087 million. Had we not received the waiver from the SEC, the impairment charge recorded would have been an additional $539 million for the year ended December 31, 2018. 2020. Due to the improvement in commodity prices during 2021, no impairment charge would have been recorded in 2021 had the Montage natural gas and oil properties been included in the full cost ceiling test.
See “Supplemental Oil and Gas Disclosures” in Item 8 of Part II of this Annual Report for additional information regarding our unevaluated costs excluded from amortization.

Operating costs and expenses remained flat over the periods presented.
The margin generated from marketing activities increased $56 million for the year ended December 31, 2021, as compared to the prior year, primarily due to a 36% increase in volumes marketed and a corresponding reduction in third-party purchases and sales, which were used in 2020 to optimize our transportation folio, due to increased affiliated volumes available for marketing.
Marketing margins are driven primarily by volumes marketed and may fluctuate depending on the prices paid for commodities, related cost of transportation and the ultimate disposition of those commodities.  Increases and decreases in revenues due to changes in commodity prices and volumes marketed are largely offset by corresponding changes in purchase expenses.  Efforts to optimize the cost of our transportation can result in greater expenses and therefore lower marketing margins.

AsIn 2020, due to significant pricing declines and the material write-down of the first quartercarrying value of 2019, we had sustained a three-year cumulative level of profitability. Based on this factorour natural gas and oil properties in addition to other positivenegative evidence, including forecasted income, wemanagement concluded that it was more likely than not that thea portion of our deferred tax assets would not be realized and determined that $522 millionrecorded a valuation allowance. As of theDecember 31, 2021, we still maintain a full valuation allowance will be released. As a result, a net tax benefit was recorded during 2019 of $411 million, which was primarily comprised of a deferred tax benefit of $522 million related to the valuation allowance release offset by the recognition of deferred tax expense of $112 million related to taxes on pre-tax income.allowance. We expect to retainalso retained a valuation allowance of $87$59 million related to net operating losses in jurisdictions in which we no longer operate.
Our low effective Management will continue to assess available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit the use of deferred tax rate in 2018 was the resultassets. The amount of our recognition of a valuation allowance that reduced the deferred tax asset primarily related to our current net operating loss carryforward, as well asconsidered realizable, however, could be adjusted based on changes in subjective estimates of future taxable income or if objective negative evidence is no longer present.
Due to the deferred tax rate enacted underissuance of common stock associated with the Tax Reform Act.  A valuation allowance for deferred tax assets, includingIndigo Merger, as discussed in Note 2 to the consolidated financial statements to this Annual Report, we incurred a cumulative ownership change and as such, our net operating losses is recognized when it is more likely than not(“NOLs”) prior to the acquisition are subject to an annual limitation under Internal Revenue Code Section 382 of approximately $48 million. The ownership changes and resulting annual limitation will result in the expiration of NOLs or other tax attributes otherwise available, with a corresponding decrease in our valuation allowance. At December 31, 2021, we had approximately $4 billion of federal NOL carryovers, of which approximately $3 billion have an expiration date between 2035 and 2037 and $1 billion have an indefinite carryforward life. We currently estimate that some or allapproximately $2 billion of the benefit from the deferredthese federal NOLs will expire before they are able to be used.

LIQUIDITY AND CAPITAL RESOURCES
We depend primarily on funds generated from our operations, our secured revolving2018 credit facility, our cash and cash equivalents balance and capital markets as our primary sources of liquidity.  In October 2021, the banks participating in our 2018 credit facility reaffirmed our elected borrowing base and aggregate commitments to be $2.0 billion. At December 31, 2021, we had approximately $1.4 billion of total available liquidity, which exceeds our currently modeled needs as we remain committed to our strategy of capital discipline.
In November 2021 in conjunction with the GEPH Merger, we amended our 2018 credit facility agreement to permit access to additional secured debt capacity in the form of a term loan for incremental capital up to $900 million, ranking equally with our 2018 credit facility. In December 2021, we raised $550 million in term loan financing to partially fund the GEPH Merger, with no impact to our liquidity at year end. The remaining $350 million of incremental term loan capacity remains accessible through November 2022 and provides access to another secured debt capital source for liquidity purposes.
Our flexibility to access incremental secured debt capital is derived from our excess asset collateral value above the elected $2.0 billion borrowing base and aggregate commitments of our 2018 credit facility. Our ability to issue secured debt is governed by the limitations of our 2018 credit facility as well as our secured debt capacity (as defined by our senior note indentures) which was $3.7 billion as of December 31, 2021, based on 25% of adjusted consolidated net tangible assets.
Looking forward in 2022, we expect to continue to generate free cash flow from operations, net of changes in working capital, in excess of our expected capital investments, and we intend to utilize this free cash flow to pay down our debt. We refer you to Note 9 to the consolidated financial statements included in this Annual Report and the section below under “Credit Arrangements and Financing Activities” for additional discussion of our revolving credit facility. Looking forward to 2020, although we have financial flexibility with our ability to draw on the $1.8 billion in available liquidity under our revolving2018 credit facility as of December 31, 2019, we remain committed to our capital discipline strategy of investing within our cash flow from operations net of changes in working capital, supplemented by a portion of the remaining net proceeds from the Fayetteville Shale sale realized in December 2018 that in the meantime was used to reduce outstanding debt. See Note 3 to the consolidated financial statements included in this Annual Report for additional discussion of the Fayetteville Shale sale.

In December 2018, we closed on the Fayetteville Shale sale and received net proceeds of approximately $1,650 million after customary purchase price adjustments. From the net proceeds received, $914 million was immediately used to repurchase $900 million of our outstanding senior notes along with related accrued interest and retirement premiums paid, $201 million was used in late 2018 and early 2019 to repurchase over 44 million shares of our outstanding common stock and the remainder was earmarked to supplement our 2019 and 2020 capital investing programs. Rather than hold these proceeds as cash and cash equivalents during this time, we chose to repurchase or pay down outstanding debt until such time that the sale proceeds would be used to supplement our capital investing program. Accordingly, as our 2020 capital investing program is expected to exceed our cash flow from operations, net of changes in working capital, supplemented by Fayetteville Shale sale proceeds, we plan on drawing no more than $300 million of the remaining earmarked sale proceeds from our revolving credit facility.covenant requirements.
Our cash flow from operating activities is highly dependent upon our ability to sell and the sales prices that we receive for our natural gas and liquids production.  Natural gas, oil and NGL prices are subject to wide fluctuations and are driven by market supply and demand, which is impacted by many factors.  See "Market Conditions and Commodity Prices" in the Overview section of Item 7 in Part II for additional discussion about current and potential future market conditions. The sales price we realizereceive for our production is also influenced by our commodity hedging activities.derivative program.  Our derivative contracts allow us to ensure a certain level of cash flow to fund our operations.  In 2019, gains on derivatives have offset a large portion of the impact of the recent decline in prices, andAlthough we currently haveare continually adding additional derivative positions in place for portions of our expected 2020, 20212022, 2023 and 20222024 production, at prices above current market levels. Therethere can be no assurance that we will be able to add derivative positions to cover the

remainder of our expected production at favorable prices. See “Risk Factors” in Item 1A, “Quantitative and Qualitative Disclosures about Market Risk” in Item 7A and Note 6 toin the consolidated financial statements included in this Annual Report for further details.
Our commodity hedging activities are subject to the credit risk of our counterparties being financially unable to settle the transaction.  We actively monitor the credit status of our counterparties, performing both quantitative and qualitative assessments based on their credit ratings and credit default swap rates where applicable, and to date have not had any credit defaults associated with our transactions.  However, any future failures by one or more counterparties could negatively impact our cash flow from operating activities.
Our short-term cash flows are also dependent on the timely collection of receivables from our customers and joint interest owners.  We actively manage this risk through credit management activities and, through the date of this filing, have not experienced any significant write-offs for non-collectable amounts.  However, any sustained inaccessibility of credit by our customers and joint interest partnersowners could adversely impact our cash flows.
Due to the abovethese factors, we are unable to forecast with certainty our future level of cash flow from operations.  Accordingly, we expect to adjust our discretionary uses of cash depending upon available cash flow.  Further, we may from time to time seek to retire, rearrange or amend some or all of our outstanding debt or debt agreements through cash purchases, and/or exchanges, open market purchases, privately negotiated transactions, tender offers or otherwise.  Such transactions, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors.  The amounts involved may be material.

In December 2021, we entered into our secured Term Loan facility and, as of December 31, 2021, had borrowings of $550 million outstanding. The net proceeds from the initial loans of $542 million were used to fund a portion of the GEPH Merger on December 31, 2021.
In December 2021, we repaid the outstanding balance of $81 million related to GEPH’s revolving credit facility.
In September 2021, we repaid the outstanding balance of $95 million related to Indigo’s revolving credit facility.
In August 2021, we completed a public offering of $1,200 million aggregate principal amount of our 2030 Notes, with net proceeds from the offering totaling $1,183 million after underwriting discounts and offering expenses. The net proceeds were used to repurchase the $791 million principal amount of certain of our outstanding senior notes. The remaining proceeds were used to pay borrowings under our 2018 credit facility and for general corporate purposes, including consideration for the Indigo Merger.
In November 2020, we paid $522 million to retire the Montage senior notes, and repaid the outstanding balance of $200 million related to Montage’s revolving credit facility.
In August 2020, we completed an underwritten public offering of 63,250,000 shares of our common stock forwith an offering price to the public of $2.50 per share. Net proceeds after deducting underwriting discounts and offering expenses were approximately $21$152 million.

Working Capital
We had negative working capital of $169$1,639 million at December 31, 2019,2021, a $279$1,298 million decrease from December 31, 2018,2020, as a decrease of $236$792 million increase in accounts receivable as compared to December 31, 2018, primarily related to the sale of the Fayetteville Shale production in December 2018 and lower commodity prices, a decrease of $196 million in cash and cash equivalents and a current liability of $34 million recorded in 2019 related to the implementation of the new lease accounting standard (Topic 842), were only partially offset by a $102$15 million increase in cash were more than offset by $1,092 million reduction in the net current mark-to-market value of our derivativederivatives position related to improved forward pricing across all commodities, along with a $745 million increase in various payables and an $84the reclassification of long-term debt to short-term debt of $206 million. Additionally, other current liabilities at December 31, 2021 increased $55 million, decrease in accounts payable, as compared to December 31, 2018.2020, primarily due to the assumption of $47 million in liabilities related to the Indigo Merger and $8 million in prepayments/collateral received from certain customers. We believe that our existing cash and cash equivalents, our anticipated cash flow from operations and our available credit facility will be sufficient to meet our working capital and operational spending requirements.
Off-Balance Sheet Arrangements
We may enter into off-balance sheet arrangements and transactions that can give rise to material off-balance sheet obligations.  As of December 31, 2019,2021, our material off-balance sheet arrangements and transactions include operating service arrangements $172and $160 million in letters of credit outstanding against our 2018 revolving credit facility and $55 million in outstanding surety bonds.facility.  There are no other transactions, arrangements or other relationships with unconsolidated entities or other persons that are reasonably likely to materially affect our liquidity or availability of our capital resources.  For more information regarding off-balance sheet arrangements, we refer you to “Contractual Obligations and Contingent Liabilities and Commitments” below for more information on our operating leases.

(1)As of December 31, 2019,2021, we had commitments for demand and similar charges under firm transportation and gathering agreements to guarantee access capacity on natural gas and liquids pipelines and gathering systems.  Of the total $8.5$10.5 billion, $1.1 billion$872 million related to access capacity on future pipeline and gathering infrastructure projects that still require the granting of regulatory approvals andand/or additional construction efforts.  For further information, we refer you to “Operational Commitments and Contingencies” in Note 10 to the consolidated financial statements included in this Annual Report.  This amount also included guarantee obligations of up to $293$869 million.
IncludedPrior to the Indigo Merger, in the transportation charges above is $108 million (due in less than one year)May 2021, Indigo closed on an agreement to divest its Cotton Valley natural gas and oil properties. Indigo retained certain contractual commitments related to certain agreements that remain involume commitments associated with natural gas gathering, for which Southwestern will assume the name of our marketing affiliate but are expectedobligation to be paid in full by Flywheel Energy Operating, LLC,pay the purchasergathering provider for any unused portion of the Fayetteville Shale assets.  Of these amounts, we may be obligated to reimburse Flywheel Energy Operating, LLC, for a portion of volumetric shortfalls during 2020 (up to $58 million)volume commitment under these transportation agreements and have currently recorded a $46 million liability asthe agreement through 2027, depending on the buyer’s actual use. As of December 31, 2019, down2021, up to approximately $36 million of these contractual commitments remain (included in the table above), and the Company has recorded a $17 million liability for its portion of the estimated future payments.
Includes firm transportation commitments acquired with the Montage Merger totaling approximately $976 million. These commitments approximate $96 million within the next year, $192 million from $881 to 3 years, $189 million recorded at December 31, 2018.from 3 to 5 years, $270 million from 5 to 8 years and $229 million beyond 8 years.
In the first quarter of 2019, we agreed to purchase firm transportation with pipelines in the Appalachian basin starting in 2021 and running through 2032, totaling $357with $327 million in total contractual commitments remaining of which the seller has agreed to reimburse $133$100 million of these commitments.
In February 2020, we were notified that the proposed Constitution pipeline project was cancelled and that we were released from a firm transportation agreement with its sponsor. As of December 31, 2019, we had contractual commitments totaling $512 million over the next seventeen years related to the Constitution pipeline project that are reflected in the table above as transportation obligations that were pending regulatory approval and/or construction. These amounts are $6 million within one to three years, $68 million within three to five years, $102 million within five to eight years and $336 million more than eight years forward.
(2)Interest payments on our senior notes were calculated utilizing the fixed rates associated with our fixed rate notes outstanding at December 31, 2019.2021.  Senior note interest rates were based on our credit ratings as of December 31, 2019.2021.
(3)Operating leases include costs for compressors, drilling rigs, pressure pumping equipment, office space and other equipment under non-cancelable operating leases expiring through 2029.2036.
During the second quarter of 2019, we executed an agreement to convey our purchase option in our headquarters office building to a third-party, which closed on the purchase of the building in July 2019. Concurrent with the closing of the building sale, we terminated our existing lease agreement and entered into a new 10-year lease agreement for a smaller portion of the headquarters building in July 2019, resulting in an estimated annual savings of $7 million to $8 million.
(4)As of December 31, 2019,2021, our E&P segment had commitments of approximately $37$38 million for compression services associated primarily with our Southwest Appalachia division.
(5)Our other significant contractual obligations include approximately $12$10 million for various information technology support and data subscription agreements.
Future contributions to the pension and postretirement benefit plans are excluded from the table above.  For further information regarding our pension and other postretirement benefit plans, we refer you to Note 1313 to the consolidated financial statements included in this Annual Report and “Critical Accounting Policies and Estimates” below for additional information.
We refer you to Note 9 to the consolidated financial statements included in this Annual Report for a discussion of the terms of our debt.  
We are subject to various litigation, claims and proceedings that arise in the ordinary course of business, such as for alleged breaches of contract, miscalculation of royalties, employment matters, traffic incidents, pollution, contamination, encroachment on others’ property or nuisance.  We accrue for such items when a liability is both probable and the amount can be reasonably estimated. Management believes that current litigation, claims and proceedings, individually or in aggregate and after taking into account insurance, are not likely to have a material adverse impact on our financial position, results of operations or cash flows, although it is possible that adverse outcomes could have a material adverse effect on our results of operations or cash flows for the period in which the effect of that outcome becomes reasonably estimable.  Many of these matters are in early stages, so the

Supplemental Guarantor Financial Information
As discussed in Note 9, in April 2018 the Company entered into the 2018 credit facility. Pursuant to requirements under the indentures governing our senior notes, each 100% owned subsidiary that became a guarantor of the 2018 credit facility also became a guarantor of each of our senior notes (the “Guarantor Subsidiaries”). The Guarantor Subsidiaries also granted liens and security interests to support their guarantees under the 2018 credit facility but not of the senior notes. These guarantees are full and unconditional and joint and several among the Guarantor Subsidiaries. Certain of our operating units which are accounted for on a consolidated basis do not guarantee the 2018 credit facility and senior notes.
Upon the closing of the Mergers, discussed further in Note 2 to the consolidated financials included in this Annual Report, certain acquired entities owning oil and gas properties became guarantors to the 2018 credit facility.
The Company and the Guarantor Subsidiaries jointly and severally, and fully and unconditionally, guarantee the payment of the principal and premium, if any, and interest on the senior notes when due, whether at stated maturity of the senior notes, by acceleration, by call for redemption or otherwise, together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Company to the holders of the senior notes.

SEC Regulation S-X Rule 13-01 requires the presentation of “Summarized Financial Information” to replace the “Condensed Consolidating Financial Information” required under Rule 3-10. Rule 13-01 allows the omission of Summarized Financial Information if assets, liabilities and results of operations of the Guarantors are not materially different than the corresponding amounts presented in the consolidated financial statements of the Company. The Parent and Guarantor Subsidiaries comprise the material operations of the Company. Therefore, the Company concluded that the presentation of the Summarized Financial Information is not required as the Summarized Financial Information of the Company’s Guarantors is not materially different from our consolidated financial statements.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
The discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States.  The preparation of these financial statements requires management to make estimates and judgments that affect the amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities.  We evaluate our estimates on an on-going basis, based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances.  Actual results may differ from these estimates under different assumptions or conditions.  We believe the following describes significant judgments and estimates used in the preparation of our consolidated financial statements.
Natural Gas and Oil Properties
We utilize the full cost method of accounting for costs related to the exploration, development and acquisition of natural gas and oil properties.  Under this method, all such costs (productive and nonproductive), including salaries, benefits and other internal costs directly attributable to these activities, are capitalized on a country-by-country basis and amortized over the estimated lives of the properties using the units-of-production method.  These capitalized costs are subject to a quarterly ceiling test that limits such pooled costs, net of applicable deferred taxes, to the aggregate of the present value of future net revenues attributable to proved natural gas, oil and NGL reserves discounted at 10% (standardized measure) plus the lower of cost or market value of unproved properties.  Any costs in excess of the ceiling are written off as a non-cash expense.  The expense may not be reversed in future periods, even though higher natural gas, oil and NGL prices may subsequently increase the ceiling.  Companies using the full cost method are required to use the average quoted price from the first day of each month from the previous 12 months, including the impact of derivatives qualifying as cash flow hedges,designated for hedge accounting, to calculate the ceiling value of their reserves. Prices used to calculate the ceiling value of reserves were as follows:
December 31, 2021December 31, 2020
Natural gas (per MMBtu)
$3.60 $1.98 
Oil (per Bbl)
$66.56 $39.57 
NGLs (per Bbl)
$28.65 $10.27

Table of Contents
Index to Financial Statements
Using the average quoted prices above, adjusted for market differentials, our net book value of our United States natural gas and oil properties did not exceed the ceiling amount at December 31, 2021. We had no derivative positions that were designated for hedge accounting as of December 31, 2021.  Future decreases in market prices, as well as changes in production rates, levels of reserves, evaluation costs excluded from amortization, future development costs and production costs may result in future non-cash impairments to our natural gas and oil properties.
The net book value of our natural gas and oil properties exceeded the ceiling amount in each quarter of 2020 resulting in a total non-cash full cost ceiling test impairment of $2,825 million.  We had no derivative positions that were designated for hedge accounting as of December 31, 2020.
No impairment expense was recorded in 2020 or 2021 in relation to our natural gas and oil properties acquired from Montage. These properties were recorded at fair value as of November 13, 2020, in accordance with ASC Topic 820 – Fair Value Measurement. In the fourth quarter of 2020, pursuant to SEC guidance, we determined that the fair value of the properties acquired at the closing of the Montage Merger clearly exceeded the related full-cost ceiling limitation beyond a reasonable doubt and received a waiver from the SEC to exclude the properties acquired in the Montage Merger from the ceiling test calculation. This waiver was granted for all reporting periods through and including the quarter ending September 30, 2021, as long as we could continue to demonstrate that the fair value of properties acquired clearly exceeded the full cost ceiling limitation beyond a reasonable doubt in each reporting period. As part of the waiver received from the SEC, we were required to disclose what the full cost ceiling test impairment amounts for all periods presented in each applicable quarterly and annual filing would have been if the waiver had not been granted. The fair value of the properties acquired in the Montage Merger was based on future commodity market pricing for natural gas and oil pricing existing at the date of the Montage Merger, and we affirmed that there has not been a material decline to the fair value of these acquired assets since the Montage Merger. The properties acquired in the Montage Merger had an unamortized cost at December 31, 2020 of $1,087 million. Had we not received the waiver from the SEC, the impairment charge recorded would have been an additional $539 million for the year ended December 31, 2020. Due to the improvement in commodity prices during 2021, no impairment charge would have been recorded in 2021 had the Montage natural gas and oil properties been included in the full cost ceiling test.
Changes in natural gas, oil and NGL prices used to calculate the discounted future net revenues of our reserves affects both the present value of cash flows and the quantity of reserves.  Our reserve base as of December 31, 2021 was approximately 82% natural gas, 2% NGLs and 16% oil, and our standardized measure and reserve quantities as of December 31, 2021, were $18.73 billion and 21.1 Tcfe, respectively.
Costs associated with unevaluated properties are excluded from our amortization base until we have evaluated the properties or impairment is indicated.  The costs associated with unevaluated leasehold acreage and related seismic data, wells currently drilling and related capitalized interest are initially excluded from our amortization base.  Leasehold costs are either transferred to our amortization base with the costs of drilling a well on the lease or are assessed at least annually for possible impairment or reduction in value.  Our decision to withhold costs from amortization and the timing of the transfer of those costs into the amortization base involves judgment and may be subject to changes over time based on several factors, including our drilling plans, availability of capital, project economics and drilling results from adjacent acreage.  At December 31, 2019,2021, we had approximately $1,506$2,231 million of costs excluded from our amortization base, all of which related to our properties in the United States.  Inclusion of some or all of these costs in our properties in the United States in the future, without adding any associated reserves, could result in non-cash ceiling test impairments.
At December 31, 2019, the ceiling value of our reserves was calculated based upon the average quoted price from the first day of each month from the previous 12 months for Henry Hub natural gas of $2.58 per MMBtu, for West Texas Intermediate oil of $55.69 per barrel and NGLs of $11.58 per barrel, adjusted for market differentials.  The net book value of our natural gas and oil properties did not exceed the ceiling amount and did not result in a ceiling test impairment at December 31, 2019.  We had no derivative positions that were designated for hedge accounting as of December 31, 2019.  Although no ceiling test impairment was recorded in 2019, given the fall in commodity prices in 2019 and early 2020 and assuming that commodity prices remain at January 2020 levels for the rest of the first quarter of 2020, we expect a non-cash impairment to our natural gas and oil properties in the first quarter of 2020 ranging from approximately $400 million to $600 million, net of tax. Future decreases in commodity prices, increases in costs and/or changes in the balance of costs excluded from amortization and other factors may result in further non-cash impairments to our natural gas and oil properties.
Using the average quoted price from the first day of each month from the previous 12 months for Henry Hub natural gas of $3.10 per MMBtu, West Texas Intermediate oil of $65.56 per barrel and NGLs of $17.64 per barrel, adjusted for market differentials, the net book value of our United States natural gas and oil properties did not exceed the ceiling amount and did not

result in a ceiling test impairment at December 31, 2018.  We had no derivative positions that were designated for hedge accounting as of December 31, 2018.
A decline inProved natural gas, oil and NGL prices used to calculatereserves are a major component of the discounted future net revenues of our reserves affects both the present value of cash flows and the quantity of reserves.  In the past, nearly all of our reserve base was natural gas; therefore changes in oil and NGL prices did not have as significant an impact as natural gas prices on cash flows and reserve quantities.  However, with the sale of our Fayetteville Shale assets in 2018 and our strategic shift towards developing our liquids-rich assets in recent years, our reserve base as of December 31, 2019 was approximately 68% natural gas, 29% NGLs and 3% oil.  Therefore, NGL and oil pricing will have a more significant impact on the cash flows and quantity of reserves going forward.  Our standardized measure and reserve quantities as of December 31, 2019, were $3.7 billion and 12.7 Tcfe, respectively.
full cost ceiling test. Natural gas, oil and NGL reserves cannot be measured exactly.  Our estimate of natural gas, oil and NGL reserves requires extensive judgments of reservoir engineering data and projections of costs that will be incurred in developing and producing reserves and is generally less precise than other estimates made in connection with financial disclosures.  Our reservoir engineers prepare our reserve estimates under the supervision of our management.  Reserve estimates are prepared for each of our properties annually by the reservoir engineers assigned to the asset management team for that property.  The reservoir engineering and financial data included in these estimates are reviewed by senior engineers, who are not part of the asset management teams, and by our Director of Reserves, who is the technical person primarily responsible for overseeing the preparation of our reserves estimates. Our Director of Reserves has more than 2527 years of experience in petroleum engineering, including the estimation of natural gas and oil reserves, and holds a Bachelor of Science in Petroleum Engineering.  Prior to joining us in 2018, our Director of Reserves served in various reservoir engineering roles for EP Energy Company, El Paso Corporation, Cabot Oil & Gas Corporation, Schlumberger and H.J. Gruy & Associates, and is a member of the Society of Petroleum Engineers.  He reports to our Executive Vice President and Chief Operating Officer, who has more than 3133 years of experience in petroleum engineering including the estimation of natural gas, oil and NGL reserves in multiple basins in the United States, and holds a Bachelor of Science in Petroleum Engineering.  Prior to joining Southwestern in 2017, our Chief Operating Officer served in various engineering and leadership roles for EP Energy

We engage NSAI, a worldwide leader of petroleum property analysis for industry and financial organizations and government agencies, to independently audit our proved reserves estimates as discussed in more detail below.  NSAI was founded in 1961 and performs consulting petroleum engineering services under Texas Board of Professional Engineers Registration No. F-002699. Within NSAI, the two technical persons primarily responsible for auditing our proved reserves estimates (1) have over 3824 years and over 1720 years of practical experience in petroleum geosciences and petroleum engineering, respectively; (2) have over 2813 years and over 1720 years of experience in the estimation and evaluation of reserves, respectively; (3) each has a college degree; (4) each is a Licensed Professional Geoscientist in the State of Texas or a Licensed Professional Engineer in the State of Texas; (5) each meets or exceeds the education, training, and experience requirements set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers; and (6) each is proficient in judiciously applying industry standard practices to engineering and geoscience evaluations as well as applying SEC and other industry reserves definitions and guidelines. The financial data included in the reserve estimates is also separately reviewed by our accounting staff. Our proved reserves estimates, as internally reviewed and audited by NSAI, are submitted for review and approval to our President and Chief Executive Officer.  Finally, upon his approval, NSAI reports the results of its reserve audit to the Board of Directors, with whom final authority over the estimates of our proved reserves rests.  A copy of NSAI’s report has been filed as Exhibit 99.1 to this Annual Report. 
Proved developed reserves generally have a higher degree of accuracy in this estimation process, when compared to proved undeveloped and proved non-producing reserves, as production history and pressure data over time is available for the majority of our proved developed properties.  Proved developed reserves accounted for 50%54% of our total reserve base as of December 31, 2019.2021.  Assigning monetary values to such estimates does not reduce the subjectivity and changing nature of such reserve estimates.  The uncertainties inherent in the reserve estimates are compounded by applying additional estimates of the rates and timing of future production volumes and the costs that will be incurred in developing and producing the reserves.  We cannot assure you that our internal controls sufficiently address the numerous uncertainties and risks that are inherent in estimating quantities of natural gas, oil and NGL reserves and projecting future rates of production and timing of development expenditures as many factors are beyond our control.  We refer you to “Our proved natural gas, oil and NGL reserves are estimates that include uncertainties.  Any material changes to these uncertainties or underlying assumptions could cause the quantities and net present value of our reserves to be overstated or understated” in Item 1A, “Risk Factors,” of Part I of this Annual Report for a more detailed discussion of these uncertainties, risks and other factors.

In conducting its audit, the engineers and geologists of NSAI study our major properties in detail and independently develop reserve estimates.  NSAI’sNSAI's audit consists primarily of substantive testing, which includes a detailed review of majorall operated proved developed properties thatplus all proved undeveloped locations. The proved developed properties included in the NSAI audit account for approximately 99% of the present worthproved developed reserve volume and 99% of the company’s total proved reserves.  NSAI’s audit process consists of sorting all fields by descending present value order and selecting the fields from highest value to descending value until the selected fields account for more than 80% of thedeveloped present worth of our reserves.  The fields included in approximately the top 99% present value as of December 31, 2019, accounted2021. The proved undeveloped properties included in the NSAI audit account for approximately 99% of our total proved reserves and approximately 100% of ourthe proved undeveloped reserves.reserve volume and 100% of the proved undeveloped present worth as of December 31, 2021.  In the conduct of its audit, NSAI did not independently verify the data we provided to them with respect to ownership interests, natural gas, oil and NGL production, well test data, historical costs of operation and development, product prices, or any agreements relating to current and future operations of the properties and sales of production.  NSAI has advised us that if, in the course of its audit, something came to its attention that brought into question the validity or sufficiency of any such information or data, NSAI did not rely on such information or data until it had satisfactorily resolved any questions relating thereto or had independently verified such information or data.  On February 7, 2020,January 28, 2022, NSAI issued its audit opinion as to the reasonableness of our reserve estimates for the year-ended December 31, 20192021 stating that our estimated proved natural gas, oil and NGL reserves are, in the aggregate, reasonable and have been prepared in accordance with Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers.
AssetsBusiness Combinations
We account for business combinations under the acquisition method of accounting. Accordingly, we recognize amounts for identifiable assets acquired and liabilities held for sale are subjectassumed equal to an assessmenttheir estimated acquisition date fair values. We make various assumptions in estimating the fair values of assets acquired and liabilities assumed. As fair value which includes many keyis a market-based measurement, it is determined based on the assumptions that market participants would use. The most significant assumptions relate to the estimated fair values of proved and unproved oil and natural gas properties. Fair value of proved natural gas and oil properties as of the acquisition date was based on estimated proved natural gas, oil and NGL reserves and related discounted net cash flows. Significant inputs to the valuation include estimates inputs and assumptions including but not limited to:of future production forecasts, pricing, basis differentials,volumes, future operating and general and administrative expense forecasts, future development costs, discountfuture commodity prices and a weighted average cost of capital rate. The market-based weighted average cost of capital rate determinationis subjected to additional project-specific risking factors. In addition, when appropriate, we review comparable purchases and sales of natural

gas and oil properties within the same regions, and use that data as a proxy for fair market value as this is an indication of the amount that a willing buyer and seller would enter into in exchange for such properties. Any excess of the acquisition price over the estimated fair value of net assets acquired is recorded as goodwill. Any excess of the estimated fair value of net assets acquired over the acquisition price is recorded in current earnings as a gain on bargain purchase. Deferred taxes are recorded for any differences between the assigned values and the tax inputs. In the third quarterbasis of 2018, we recognized certain assets and liabilities.

The Mergers qualified as business combinations, and as such, we estimated the fair values of the assets acquired and liabilities assumed as held for sale related to the Fayetteville Shale sale requiring a comparison of their respective carrying cost and fair value less costs to sell. Our full cost pool assets were excluded from held for sale accounting treatment as they are governed by SEC Regulation S-X Rule 4-10.acquisition dates. The fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Fair value measurements also utilize assumptions of our gathering assets to be sold was estimated using an estimatedmarket participants. We used discounted cash flow model along withmodels and we made market assumptions.  The assumptions used in the calculation of estimated discounted cash flows includedas to future commodity prices, projections of estimated quantities of natural gas and oil reserves, expectations for timing and amount of future development and operating costs, projections of future rates of production, inflation factorsexpected recovery rates and risk-adjustedrisk adjusted discount rates.

Under full cost accounting rules, salesWe recorded the net assets acquired and liabilities assumed in the Montage Merger at their estimated fair value on November 13, 2020 of oilapproximately $213 million.
We recorded the net assets acquired and gas properties, whether or not being amortized currently, shallliabilities assumed in the Indigo Merger at their estimated fair value on September 1, 2021 of approximately $1,961 million.
We recorded the net assets acquired and liabilities assumed in the GEPH Merger at their estimated fair value on December 31, 2021 of approximately $1,732 million.
We consider the estimated fair values above to be accounted for as a reductionrepresentative of the full cost pool, withprices paid by typical market participants. These measurements resulted in no gaingoodwill or loss recognized, unless such adjustments would significantly alter the relationship between capitalized costs and proved reserves of oil and gas attributable to a cost center.  For instance, a significant alteration would not ordinarily be expected to occur for sales involving less than 25 percent of the reserve quantities of a given cost center.   Judgments are required around the determination of whether a divestment is deemed significant.  Such judgments include an assessment of the of the reserve quantities sold as compared to total reserve quantities and other qualitative and quantitative assessments of the relationship between capitalized costs and proved reserves.  We did not recognize a gain or loss on the sale of our oil and gas properties as the divestment was deemed not significant.  Please refer to Note 3 to the consolidated financial statements included in this Annual Report for further detail.bargain purchases being recognized.
Derivatives and Risk Management
We use fixed price swap agreements and options to reduce the volatility of earnings and cash flow due to fluctuations in the prices of certain commodities and interest rates.  Our policies prohibit speculation with derivatives and limit agreements to counterparties with appropriate credit standings to minimize the risk of uncollectability.  We actively monitor the credit status of our counterparties based on their credit ratings and credit default swap rates where applicable, and to date have not had any credit defaults associated with our transactions.  In both 20192021 and 2018,2020, we financially protected 69%83% of our total production with derivatives.  The primary risks related to our derivative contracts are the volatility in market prices and basis differentials for our production.  However, the market price risk is generally offset by the gain or loss recognized upon the related transaction that is financially protected.
All derivatives are recognized in the balance sheet as either an asset or a liability as measured at fair value other than transactions for which the normal purchase/normal sale exception is applied.  Certain criteria must be satisfied for derivative financial instruments to be designated for hedge accounting. Accounting guidance for qualifying hedges allows an unsettled derivative’s unrealized gains and losses to be recorded in either earnings or as a component of other comprehensive income until settled.  In the period of settlement, we recognize the gains and losses from these qualifying hedges in gas sales revenues.  The ineffective portion of those fixed price swaps wasare recognized in earnings.  Gains and losses on derivatives that are not designated for hedge accounting treatment, or that do not meet hedge accounting requirements, are recorded as a component of gain (loss) on derivatives on the consolidated statements of operations. Accordingly, the gain (loss) on derivatives component of the statement of operations reflects the gains and losses on both settled and unsettled derivatives.  We calculate gains and losses on settled derivatives as the summation of gains and losses on positions which have settled within the reporting period.

As of December 31, 2019,2021, none of our derivative contracts were designated for hedge accounting treatment.  Changes in the fair value of unsettled derivatives that were not designated for hedge accounting treatment are recorded in gain (loss) on derivatives.  See Note 6 to the consolidated financial statements included in this Annual Report for more information on our derivative position at December 31, 2019.2021.
Future market price volatility could create significant changes to the derivative positions recorded in our consolidated financial statements.  We refer you to “Quantitative and Qualitative Disclosures about Market Risk” in Item 7A of Part II of this Annual Report for additional information regarding our hedging activities.
Pension and Other Postretirement Benefits
As part of ongoing effort to reduce costs, we have elected to freeze our pension plan effective January 1, 2021. Employees that were participants in the pension plan prior to January 1, 2021 will continue to receive the interest component of the plan but

Index to Financial Statements
will no longer receive the service component. We have commenced the pension plan termination process, but the specific date for the completion of the process is unknown at this time and will depend on certain legal and regulatory requirements or approvals. As part of the termination process, we expect to distribute lump sum payments to or purchase annuities for the benefit of plan participants, which is dependent on the participants’ elections. In addition, we expect to make a payment equal to the difference between the total benefits due under the plan and the total value of the assets available, which, as of December 31, 2021, was approximately $12 million. Our current funding policy is to continue to contribute amounts which are actuarially determined to provide the plan with sufficient assets to meet future benefit payment requirements and which are tax deductible. We are in the process of evaluating the impact of the termination and future settlement accounting on our consolidated financial statements and related disclosures.
We record our prepaid or accrued benefit cost, as well as our periodic benefit cost, for our pension and other postretirement benefit plans using measurement assumptions that we consider reasonable at the time of calculation (see Note 1313 to the consolidated financial statements included in this Annual Report for further discussion and disclosures regarding these benefit plans).  Two of the assumptions that affect the amounts recorded are the discount rate, which estimates the rate at which benefits could be effectively settled, and the expected return on plan assets, which reflects the average rate of earnings expected on the funds invested.  For the December 31, 20192021 benefit obligation and periodic benefit cost to be recorded in 2020, the initial discount rate assumed is 3.70%3.20%.  This compares to an initial discount rate of 4.35%3.10% for the benefit obligation and periodic benefit cost recorded in 2019.2021.  For the 20202022 periodic benefit cost, the expected return assumed decreasedwas reduced from 5.10% to 6.50%0.10%, as the investment allocations have shifted from 7.00%a balanced portfolio to short-term fixed-income assets in 2019.
alignment with the plan termination process. Using the assumed rates discussed above, we recorded total benefit cost of $15$4 million in 20192021 related to our pension and other postretirement benefit plans.  Due to the significance of the discount rate and expected long-term rate of return, the following sensitivity analysis demonstrates the effect thatplans, which included a 0.5% change in those assumptions would have had on our 2019 pension expense:

As of December 31, 2019,2021, we recognized a liability of $43$25 million, compared to $47$46 million at December 31, 2018,2020, related to our pension and other postretirement benefit plans.  During 2019,2021, we also made cash contributions totaling $14$12 million to fund our pension and other postretirement benefit plans.
Stock-BasedLong-term Incentive Compensation
Our long-term incentive compensation plans consist of a combination of stock-based awards that derive their value directly or indirectly from our common stock price, and cash-based awards that are fixed in amount, but subject to meeting annual performance thresholds. In March 2020, we issued our first long-term fixed cash-based awards.
We account for stock-basedlong-term incentive compensation transactions using a fair value method and recognize an amount equal to the fair value of the stock optionsstock-based awards and stock-based paymentcash-based awards cost in either the consolidated statement of operations or capitalize the cost into natural gas and oil properties included in property and equipment.  Costs are capitalized when they are directly related to the acquisition, exploration and development activities of our natural gas and oil properties.  We use models to determine fair value of stock-based compensation, which requires significant judgment with respect to forfeitures, volatility and other factors. The performance cash awards granted in 2021 and 2020 include a performance condition determined annually by the Company. If we, in our sole discretion, determine that the threshold was not met, the amount for that vesting period will not vest and will be cancelled.
Our stock-based compensation is classified as either an equity award or a liability award in accordance with generally accepted accounting principles.  The fair value of an equity-classified award is determined at the grant date and is amortized on a straight-line basis over the vesting life of the award.  The fair-value of a liability-classified award is determined on a quarterly basis through the final vesting date and is amortized based on the current fair value of the award and the percentage of vesting period incurred to date. See Note 14 to the consolidated financial statements included in this Annual Report for further discussion and disclosures regarding our long-term incentive compensation.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market risks relating to our operations result primarily from the volatility in commodity prices, basis differentials and interest rates, as well as service costs and credit risk concentrations.  We use fixed price swap agreements, options, swaptions, basis swaps and interest rate swaps to reduce the volatility of earnings and cash flow due to fluctuations in the prices of natural gas, oil and certain NGLs along with interest rates.  Our Board of Directors has approved risk management policies and procedures to utilize financial products for the reduction of defined commodity price risk.  Utilization of financial products for the reduction of interest

Credit Risk
Our exposure to concentrations of credit risk consists primarily of trade receivables and derivative contracts associated with commodities trading.  Concentrations of credit risk with respect to receivables are limited due to the large number of our purchasers and their dispersion across geographic areas.  No single purchaser accounted for greater than 10% of revenues during the year ended December 31, 2019. For the year ended December 31, 2018, two subsidiaries2021, one purchaser accounted for 12% of Royal Dutch Shell Plc in aggregateour revenues.

Interest Rate Risk
As of December 31, 2019,2021, we had approximately $2.2$4.4 billion of outstanding senior notes with a weighted average interest rate of 6.71%5.68%, and $34$550 million of borrowings under our revolvingTerm Loan facility and $460 million of borrowings under our 2018 credit facility.  We currently have an interest rate swap in effect to mitigate a portion of our exposure to volatility in interest rates.  At December 31, 2019,2021, we had a long-term debt issuer credit ratingratings of Ba2 by Moody’s, a long-term debt rating of BB by S&P and a long-term debt issuer default rating of BB by Fitch Ratings.  On September 1, 2021, S&P upgraded our bond rating to BB, and on January 6, 2022, S&P further upgraded our bond rating to BB+, which will have the effect of decreasing the interest rate on the 2025 notes to 5.95%, beginning with coupon payments paid after January 2022. Any further upgrades or downgrades in our public debt ratings by Moody’s or S&P could decrease or increase our cost of funds, respectively.

Commodities Risk
We use over-the-counter fixed price swap agreements and options to protect sales of our production against the inherent risks of adverse price fluctuations or locational pricing differences between a published index and the NYMEX futures market.  These swaps and options include transactions in which one party will pay a fixed price (or variable price) for a notional quantity in exchange for receiving a variable price (or fixed price) based on a published index (referred to as price swaps) and transactions in which parties agree to pay a price based on two different indices (referred to as basis swaps).
The primary market risks relating to our derivative contracts are the volatility in market prices and basis differentials for our production.  However, the market price risk is offset by the gain or loss recognized upon the related sale or purchase of the production that is financially protected. Credit risk relates to the risk of loss as a result of non-performance by our counterparties. The counterparties are primarily major banks and integrated energy companies that management believes present minimal credit risks. The credit quality of each counterparty and the level of financial exposure we have to each counterparty are closely monitored to limit our credit risk exposure. Additionally, we perform both quantitative and qualitative assessments of these counterparties based on their credit ratings and credit default swap rates where applicable. We have not incurred any counterparty losses related to non-performance and do not anticipate any losses given the information we have currently. However, we cannot be certain that we will not experience such losses in the future.  The fair value of our derivative assets and liabilities includes a non-performance risk factor.

Management’s Report on Internal Control Over Financial Reporting
It is the responsibility of the management of Southwestern Energy Company to establish and maintain adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934). Management has assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2019,2021, utilizing the Committee of Sponsoring Organizations of the Treadway Commission’s Internal Control – Integrated Framework (2013).
Based on this evaluation, management has concluded the Company’s internal control over financial reporting was effective as of December 31, 2019. 2021.
The effectiveness of our internal control over financial reporting as of December 31, 20192021 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report which appears herein.
Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders of Southwestern Energy Company
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Southwestern Energy Company and its subsidiaries (the “Company”) as of December 31, 20192021 and 2018,2020, and the related consolidated statements of operations, of comprehensive income (loss), of changes in equity and of cash flows for each of the three years in the period ended December 31, 2019,2021, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2019,2021, based on criteria established in Internal Control - Integrated Framework(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 20192021 and 2018,2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 20192021 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company’sCompany's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’sCompany's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that
7279

Table of Contents
Index to Financial Statements
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters

The Impact of Proved Natural Gas, Oil and NGL Reserves on Proved Natural Gas and Oil Properties Net
The Company’s consolidated property and equipment, net balance was $5,267 million as of December 31, 2019, and depreciation, depletion, and amortization (DD&A) expense for the year ended December 31, 2019 was $471 million, both of which substantially relate to proved natural gas and oil properties. As described in Note 1 to the consolidated financial statements, the Company’s consolidated natural gas and oil properties balance was $33,631 million as of December 31, 2021, and depreciation, depletion and amortization expense for the year ended December 31, 2021 was $546 million. The Company utilizes the full cost method of accounting for its natural gas and oil producing properties. Under this method, all capitalized costs are amortized over the estimated lives of the properties using the unit-of-production method based on proved natural gas, oil and NGLnatural gas liquids (NGL) reserves. These capitalized costs are subject to a ceiling test that limits such pooled costs, net of applicable deferred taxes, to the aggregate of the present value of future net revenues attributable to proved natural gas, oil and NGL reserves discounted at 10%. In 2019, the Company did not have any ceiling test impairments on its proved natural gas and oil properties. As disclosed by management, estimates ofproved natural gas, oil and NGL reserves are a major component of the full cost ceiling test. Estimates of reserves require extensive judgments of reservoir engineering data and projections of costs that will be incurred in developing and producing reserves. The uncertainties inherent in the reserve estimates are compounded by applying additional estimates of the rates and timing of future production volumes and the costs that will be incurred in developing and producing the reserves. The estimates of natural gas, oil and NGL reserves have been developed by specialists, specifically reservoir engineers.engineers, and audited by independent petroleum engineers (together referred to as “specialists”).
The principal considerations for our determination that performing procedures relating to the impact of proved natural gas, oil and NGL reserves on proved natural gas and oil properties net is a critical audit matter are there was(i) the significant judgment by management, including the use of management’s specialists, when developing the estimates of proved natural gas, oil and NGL reserves. Thisreserves, which in turn led to (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating audit evidence related to the significantdata, methods, and assumptions used by management and its specialists in developing thosethe estimates includingof proved natural gas, oil and NGL reserves and the assumption applied to the full cost ceiling test related to future production volumes.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s estimates of proved natural gas, oil and NGL reserves the calculation ofand the full cost ceiling impairment test and the calculation of DD&A expense. These procedures also included, among others, evaluating the significant assumptions used by management in developing these estimates, including future production volumes, testing the full cost ceiling impairment test calculation, and testing the unit-of-production rate used to calculate DD&A expense.calculation. The work of management’s specialists was used in performing the procedures to evaluate the reasonableness of the estimates of proved natural gas, oil and NGL reserves.reserves and the reasonableness of future production volumes applied in the full cost ceiling test. As a basis for using this work, specialists’ qualifications were understood and the Company’s relationship with the specialists was assessed. The procedures performed also included evaluation of the methods and assumptions used by specialists, tests of the completeness and accuracy of the data used by the specialists, and an evaluation of specialists’ findings.
Acquisitions of Indigo Natural Resources LLC and GEP Haynesville, LLC – Valuation of Proved Natural Gas and Oil Properties
As described in Note 2 to the consolidated financial statements, the Company completed the acquisitions of Indigo Natural Resources LLC and GEP Haynesville, LLC for net consideration of $1,961 million and $1,732 million, respectively, which resulted in $4,507 million of proved natural gas and oil properties being recorded from these acquisitions. As disclosed by management, the Company accounts for business combinations under the acquisition method of accounting. Accordingly, the Company recognizes amounts for identifiable assets acquired and liabilities assumed equal to their estimated acquisition date fair

values. The most significant assumptions relate to the estimated fair values of proved natural gas and oil properties. Fair value of proved natural gas and oil properties as of the acquisition date was based on estimated proved natural gas, oil, and NGL reserves and related discounted net cash flows. Significant inputs to the valuation include estimates of future production volumes, future operating and development costs, future commodity prices and a weighted average cost of capital rate. The estimates of natural gas, oil and NGL reserves have been developed by specialists, specifically reservoir engineers, and audited by independent petroleum engineers (together referred to as “specialists”).
The principal considerations for our determination that performing procedures relating to the valuation of proved natural gas and oil properties from the acquisitions of Indigo Natural Resources LLC and GEP Haynesville, LLC is a critical audit matter are (i) the significant judgment by management, including the use of management’s specialists, when developing the fair value of acquired proved natural gas and oil properties, which in turn led to (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to future production volumes, future commodity prices, and the weighted average cost of capital rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the valuation of the acquired proved natural gas and oil properties. These procedures also included, among others (i) reading the purchase agreement; (ii) testing management’s process for developing the fair value of acquired proved natural gas and oil properties; (iii) evaluating the appropriateness of the discounted cash flow models; (iv) testing the completeness and accuracy of underlying data used in the discounted cash flow models; and (v) evaluating the reasonableness of significant assumptions used by management related to future production volumes, future commodity prices, and the weighted average cost of capital rate. Evaluating the reasonableness of management’s significant assumption related to future commodity prices involved comparing the future commodity prices against observable market data and evaluating commodity price differentials through inspection of the underlying contracts. Professionals with specialized skill and knowledge were used to assist in evaluating the appropriateness of the discounted cash flow models and the reasonableness of the weighted average cost of capital rate significant assumption. The work of management’s specialists was used in performing the procedures to evaluate the reasonableness of the proved natural gas and oil reserves as stated in the Critical Audit Matter titled “Impact of Proved Natural Gas, Oil and NGL Reserves on Natural Gas and Oil Properties” and the reasonableness of the future production volumes. As a basis for using this work, the specialists’ qualifications and objectivity were understood as well asand the Company’s relationship with the specialists was assessed. The procedures performed also included evaluation of the methods and assumptions used by the specialists. The procedures performed also includedspecialists, tests of the completeness and accuracy of the data used by the specialists, and an evaluation of the specialists’ findings.

Southwestern Energy Company (including its subsidiaries, collectively “Southwestern” orIn 2020, due to significant pricing declines and the “Company”) is an independent energy company engaged inmaterial write-down of the carrying value of our natural gas and oil properties in addition to other negative evidence, management concluded that it was more likely than not that a portion of our deferred tax assets would not be realized and NGLs exploration, developmentrecorded a valuation allowance. As of December 31, 2021, we still maintain a full valuation allowance. We also retained a valuation allowance of $59 million related to net operating losses in jurisdictions in which we no longer operate. Management will continue to assess available positive and production (“E&P”).negative evidence to estimate whether sufficient future taxable income will be generated to permit the use of deferred tax assets. The Companyamount of the deferred tax asset considered realizable, however, could be adjusted based on changes in subjective estimates of future taxable income or if objective negative evidence is also focused on creating and capturing additional value through its marketing business (“Marketing”), which was previously referredno longer present.
Due to the issuance of common stock associated with the Indigo Merger, as “Midstream” when it included the operations of gathering systems. Southwestern conducts most of its business through subsidiaries and operates principally in 2 segments: E&P and Marketing.  The Company’s historical financial and operating results include its Fayetteville Shale E&P and related midstream gathering businesses, which were sold in early December 2018 (“the Fayetteville Shale sale”). The sale is discussed in further detail in Note 32. to the consolidated financial statements to this Annual Report, we incurred a cumulative ownership change and as such, our net operating losses (“NOLs”) prior to the acquisition are subject to an annual limitation under Internal Revenue Code Section 382 of approximately $48 million. The ownership changes and resulting annual limitation will result in the expiration of NOLs or other tax attributes otherwise available, with a corresponding decrease in our valuation allowance. At December 31, 2021, we had approximately $4 billion of federal NOL carryovers, of which approximately $3 billion have an expiration date between 2035 and 2037 and $1 billion have an indefinite carryforward life. We currently estimate that approximately $2 billion of these federal NOLs will expire before they are able to be used. The non-expiring NOLs remain subject to a full valuation allowance. If a subsequent ownership change were to occur as a result of future transactions in our common stock, our use of remaining U.S. tax attributes may be further limited.
E&P.We refer you to Note 11 Southwestern’s primary business isto the exploration for and production of natural gas, oil and NGLs, with ongoing operations focused on the development of unconventional natural gas and oil reservoirs located in Pennsylvania and West Virginia. The Company’s operations in northeast Pennsylvania, herein referred to as “Northeast Appalachia,” are primarily focused on the unconventional natural gas reservoir known as the Marcellus Shale. Operations in West Virginia and southwest Pennsylvania, herein referred to as “Southwest Appalachia,” are focused on the Marcellus Shale, the Utica and the Upper Devonian unconventional natural gas and oil reservoirs. Collectively, Southwestern refers to its properties located in Pennsylvania and West Virginia as “Appalachia.” The Company also operates drilling rigs located in Pennsylvania and West Virginia, and provides oilfield products and services, principally serving the Company's E&P operations through vertical integration.
Marketing. Southwestern’s marketing activities capture opportunities that arise through the marketing and transportation of natural gas, oil and NGLs primarily produced in its E&P operations.
Basis of Presentation
The consolidated financial statements included in this Annual Report presentfor additional discussion about our income taxes.
LIQUIDITY AND CAPITAL RESOURCES
We depend primarily on funds generated from our operations, our 2018 credit facility, our cash and cash equivalents balance and capital markets as our primary sources of liquidity.  In October 2021, the Company’sbanks participating in our 2018 credit facility reaffirmed our elected borrowing base and aggregate commitments to be $2.0 billion. At December 31, 2021, we had approximately $1.4 billion of total available liquidity, which exceeds our currently modeled needs as we remain committed to our strategy of capital discipline.
In November 2021 in conjunction with the GEPH Merger, we amended our 2018 credit facility agreement to permit access to additional secured debt capacity in the form of a term loan for incremental capital up to $900 million, ranking equally with our 2018 credit facility. In December 2021, we raised $550 million in term loan financing to partially fund the GEPH Merger, with no impact to our liquidity at year end. The remaining $350 million of incremental term loan capacity remains accessible through November 2022 and provides access to another secured debt capital source for liquidity purposes.
Our flexibility to access incremental secured debt capital is derived from our excess asset collateral value above the elected $2.0 billion borrowing base and aggregate commitments of our 2018 credit facility. Our ability to issue secured debt is governed by the limitations of our 2018 credit facility as well as our secured debt capacity (as defined by our senior note indentures) which was $3.7 billion as of December 31, 2021, based on 25% of adjusted consolidated net tangible assets.
Looking forward in 2022, we expect to continue to generate free cash flow from operations, net of changes in working capital, in excess of our expected capital investments, and we intend to utilize this free cash flow to pay down our debt. We refer you to Note 9 to the consolidated financial statements included in this Annual Report and the section below under “Credit Arrangements and Financing Activities” for additional discussion of our 2018 credit facility and related covenant requirements.
Our cash flow from operating activities is highly dependent upon our ability to sell and the sales prices that we receive for our natural gas and liquids production.  Natural gas, oil and NGL prices are subject to wide fluctuations and are driven by market supply and demand, which is impacted by many factors.  See "Market Conditions and Commodity Prices" in the Overview section of Item 7 in Part II for additional discussion about current and potential future market conditions. The sales price we receive for our production is also influenced by our commodity derivative program.  Our derivative contracts allow us to ensure a certain level of cash flow to fund our operations.  Although we are continually adding additional derivative positions for portions of our expected 2022, 2023 and 2024 production, there can be no assurance that we will be able to add derivative positions to cover the

remainder of our expected production at favorable prices. See “Risk Factors” in Item 1A, “Quantitative and Qualitative Disclosures about Market Risk” in Item 7A and Note 6 in the consolidated financial statements included in this Annual Report for further details.
Our commodity hedging activities are subject to the credit risk of our counterparties being financially unable to settle the transaction.  We actively monitor the credit status of our counterparties, performing both quantitative and qualitative assessments based on their credit ratings and credit default swap rates where applicable, and to date have not had any credit defaults associated with our transactions.  However, any future failures by one or more counterparties could negatively impact our cash flow from operating activities.
Our short-term cash flows are also dependent on the timely collection of receivables from our customers and joint interest owners.  We actively manage this risk through credit management activities and, through the date of this filing, have not experienced any significant write-offs for non-collectable amounts.  However, any sustained inaccessibility of credit by our customers and joint interest owners could adversely impact our cash flows.
Due to these factors, we are unable to forecast with certainty our future level of cash flow from operations.  Accordingly, we expect to adjust our discretionary uses of cash depending upon available cash flow.  Further, we may from time to time seek to retire, rearrange or amend some or all of our outstanding debt or debt agreements through cash purchases, and/or exchanges, open market purchases, privately negotiated transactions, tender offers or otherwise.  Such transactions, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors.  The amounts involved may be material.
Credit Arrangements and Financing Activities
In April 2018, we entered into a revolving credit facility (the "2018 credit facility") with a group of banks that, as amended, has a maturity date of April 2024.  The 2018 credit facility has an aggregate maximum revolving credit amount of $3.5 billion and, in October 2021, the banks participating in our 2018 credit facility reaffirmed the elected borrowing base to be $2.0 billion, which also reflected our aggregate commitments. The borrowing base is subject to redetermination at least twice a year, which typically occurs in April and October, and is subject to change based primarily on drilling results, commodity prices, our future derivative position, the level of capital investment and operating costs. The 2018 credit facility is secured by substantially all of our assets, including most of our subsidiaries. The permitted lien provisions in certain senior note indentures currently limit liens securing indebtedness to the greater of $2.0 billion or 25% of adjusted consolidated net tangible assets. We may utilize the 2018 credit facility in the form of loans and letters of credit. As of December 31, 2021, we had $460 million of borrowings on our 2018 credit facility and $160 million in outstanding letters of credit. We currently do not anticipate being required to supply a materially greater amount of letters of credit under our existing contracts. We refer you to Note 9 to the consolidated financial statements included in this Annual Report for additional discussion of our 2018 credit facility.
As of December 31, 2021, we were in compliance with all of the applicable covenants contained in the credit agreement governing our 2018 credit facility.  Our ability to comply with financial covenants in future periods depends, among other things, on the success of our development program and upon other factors beyond our control, such as the market demand and prices for natural gas and liquids.  We refer you to Note 9 of the consolidated financial statements included in this Annual Report for additional discussion of the covenant requirements of our 2018 credit facility.
The credit status of the financial institutions participating in our 2018 credit facility could adversely impact our ability to borrow funds under the 2018 credit facility.  Although we believe all of the lenders under the facility have the ability to provide funds, we cannot predict whether each will be able to meet their obligation to us.  We refer you to Note 9 to the consolidated financial statements included in this Annual Report for additional discussion of our 2018 credit facility.
Our exposure to the anticipated transition from LIBOR is limited to the 2018 credit facility. The USD-LIBOR settings are expected to be published through June 2023, and we anticipate using a variation of this rate until the underlying agreements are extended beyond the LIBOR publication date.
Key financing activities for the years ended December 31, 2021 and 2020 are as follows:
Debt and Common Stock Issuance
On December 22, 2021, we completed a public offering of $1,150 million aggregate principal amount of our 4.75% Senior Notes due 2032 (the “2032 Notes”), with net proceeds from the offering totaling $1,133 million after underwriting discounts and offering expenses. The net proceeds were used to fund a portion of the GEPH Merger, which closed on December 31, 2021, and to fund tender offers for $300 million of our 2025 Notes. The remaining proceeds were used for general corporate purposes.

In contemplation of the GEPH Merger, on December 22, 2021, we entered into a term loan credit agreement with a group of lenders that provided for a $550 million secured term loan facility which matures on June 22, 2027 (the “Term Loan”). As of December 31, 2021, we had borrowings under the Term Loan of $550 million. The net proceeds from the initial loans of $542 million were used to fund a portion of the GEPH Merger on December 31, 2021.
On December 31, 2021, we issued 99,337,748 shares of our common stock in conjunction with the GEPH Merger. These shares of our common stock had an aggregate dollar value equal to approximately $463 million, based on the closing price of $4.66 per share of our common stock on the NYSE on December 31, 2021. See Note 2 for additional details on the GEPH Merger.
In November 2021, in contemplation of the GEPH Merger, we amended our 2018 credit facility agreement to permit access to additional secured debt capacity in the form of the previously-described Term Loan for incremental capital up to $900 million, ranking equally with our 2018 credit facility. As of December 31, 2021, we had borrowings under the Term Loan of $550 million, which were used to partially fund the GEPH Merger, and $350 million of incremental term loan capacity, which remains accessible through November 2022.
In August 2021, we completed a public offering of $1,200 million aggregate principal amount of our 5.375% Senior Notes due 2030 (the “2030 Notes”), with net proceeds from the offering totaling $1,183 million after underwriting discounts and offering expenses. The proceeds were used to repurchase the $791 million principal amount of certain of our outstanding senior notes. The remaining proceeds were used to pay borrowings under our 2018 credit facility and for general corporate purposes, including consideration for the Indigo Merger.
In September 2021, we issued 337,827,171 shares of our common stock in conjunction with the Indigo Merger. These shares of our common stock had an aggregate dollar value equal to approximately $1,588 million, based on the closing price of $4.70 per share of our common stock on the NYSE on September 1, 2021. See Note 2 for additional details on the Indigo Merger.
In conjunction with the Indigo Merger and pursuant to the terms of the merger agreement, in September 2021, we assumed $700 million in aggregate principal amount of Indigo’s 5.375% Senior Notes due 2029 (the “Indigo Notes”). Subsequent to the Indigo Merger, we exchanged the Indigo Notes for approximately $700 million of newly issued 5.375% Senior Notes due 2029.
In November 2020, we issued 69,740,848 shares of our common stock in conjunction with the Montage Merger. These shares of our common stock had an aggregate dollar value equal to approximately $213 million, based on the closing price of $3.05 per share of our common stock on the NYSE on November 13, 2020. See Note 2 for additional details on the Montage Merger.
In August 2020, we completed a public offering of $350 million aggregate principal amount of our 2028 Notes, with net proceeds from the offering totaling approximately $345 million after underwriting discounts and offering expenses. The net proceeds were used to fund a portion of the Montage Merger in November 2020.
In August 2020, we completed a public offering of 63,250,000 shares of our common stock with an offering price to the public of $2.50 per share. Net proceeds, after deducting underwriting discounts and offering expenses, were approximately $152 million. The proceeds from the common stock offering, in conjunction with the issuance of the 2028 Notes and additional borrowings on our 2018 credit facility were used to fund a redemption of $510 million aggregate principal amount of Montage’s senior notes in connection with the closing of the Montage Merger.
Debt Repurchases
In 2021, we repurchased $6 million of our 4.10 % Senior Notes due 2022, $467 million of our 4.95% Senior Notes due 2025 and $618 million of our 7.50% Senior Notes due 2026 for $1,177 million in cash, including premiums and fees, and we recognized an additional $7 million in unamortized debt expenses, resulting in a loss on early extinguishment of debt of $93 million.
In 2020, we repurchased $6 million of our 4.10% Senior Notes due 2022, $36 million of our 4.95% Senior Notes due 2025, $21 million of our 7.50% Senior Notes due 2026 and $44 million of our 7.75% Senior Notes due 2027 for $72 million, and recognized a $35 million gain on the extinguishment of debt. We refer you to Note 9 to the consolidated financial statements included in this Annual Report for additional discussion of our senior notes.

In January 2022, we repurchased the remaining outstanding principal balance of $201 million on our 2022 Senior Notes using our 2018 credit facility. As a result of the focused work on refinancing and repayment of our debt in recent years, our outstanding revolver balance and $16 million of our Term Loan principal are the only debt balances scheduled to become due prior to 2025.
At February 25, 2022, we had long-term debt issuer ratings of Ba2 by Moody’s (rating and stable outlook affirmed on November 29, 2021), BB+ by S&P (rating upgraded to BB+ with stable outlook on January 6, 2022) and BB by Fitch Ratings (rating and stable outlook affirmed on November 29, 2021). Effective in July 2018, the interest rate for our 2025 Notes was 6.20%, reflecting a net downgrade in our bond ratings since their issuance. In April 2020, S&P downgraded our bond rating to BB-, which had the effect of increasing the interest rate on the 2025 Notes to 6.45% in July 2020, with the first coupon payment at the higher interest rate in January 2021. On September 1, 2021, S&P upgraded our bond rating to BB, and on January 6, 2022, S&P further upgraded our bond rating to BB+, which will have the effect of decreasing the interest rate on the 2025 Notes to 5.95%, beginning with coupon payments after January 2022. Any further upgrades or downgrades in our public debt ratings by Moody’s or S&P could decrease or increase our cost of funds, respectively.

Net cash provided by operating activities increased 158% or $835 million for the year ended December 31, 2021, compared to the same period in 2020, primarily due to a $2,768 million increase resulting from higher commodity prices, a $524 million increase related to increased production and a $56 million increase in our marketing margin. The increases were partially offset by a $1,854 million decrease in settled derivatives, a $477 million increase in operating costs and expenses, a $132 million decreased impact of working capital and a $42 million increase in interest expense.
Net cash generated from operating activities, net of changes in working capital, exceeded our capital investments by $464 million for the year ended December 31, 2021, compared to providing 67% of our cash requirements for capital investments for the same period in 2020.
Cash Flow from Investing Activities
Total E&P capital investing increased $208 million for the year ended December 31, 2021, compared to the same period in 2020, due to a $191 million increase in direct E&P capital investing, an $8 million increase in capitalized internal costs and a $9 million increase in capitalized interest.  
Capitalized interest increased for the year ended December 31, 2021, as compared to the same period in 2020, as the acquisition of Haynesville unevaluated natural gas and oil properties on September 1, 2021 outpaced the evaluation of our existing unevaluated natural gas and oil properties over the past twelve months. The impact of the addition of additional Haynesville properties from the GEPH Merger on December 31, 2021 is expected to increase the amount of capitalized interest until such time as it is evaluated.
Cash paid in mergers includes cash consideration of $373 million and $1,269 million paid for the Indigo Merger and GEPH Merger, respectively.

In December 2021, we entered into our secured Term Loan facility and, as of December 31, 2021, had borrowings of $550 million outstanding. The net proceeds from the initial loans of $542 million were used to fund a portion of the GEPH Merger on December 31, 2021.
In December 2021, we repaid the outstanding balance of $81 million related to GEPH’s revolving credit facility.
In September 2021, we repaid the outstanding balance of $95 million related to Indigo’s revolving credit facility.
In August 2021, we completed a public offering of $1,200 million aggregate principal amount of our 2030 Notes, with net proceeds from the offering totaling $1,183 million after underwriting discounts and offering expenses. The net proceeds were used to repurchase the $791 million principal amount of certain of our outstanding senior notes. The remaining proceeds were used to pay borrowings under our 2018 credit facility and for general corporate purposes, including consideration for the Indigo Merger.
In November 2020, we paid $522 million to retire the Montage senior notes, and repaid the outstanding balance of $200 million related to Montage’s revolving credit facility.
In August 2020, we completed an underwritten public offering of 63,250,000 shares of our common stock with an offering price to the public of $2.50 per share. Net proceeds after deducting underwriting discounts and offering expenses were approximately $152 million.
In 2020, we repurchased $107 million in aggregate principal amount of our outstanding senior notes at a discount for $72 million and recognized a $35 million gain on the extinguishment of debt.
We refer you to Note 9 to the consolidated financial statements included in this Annual Report for additional discussion of our outstanding debt and credit facility and to Note 1 for additional discussion of our equity offering.
Working Capital
We had negative working capital of $1,639 million at December 31, 2021, a $1,298 million decrease from December 31, 2020, as a $792 million increase in accounts receivable and a $15 million increase in cash were more than offset by $1,092 million reduction in the current mark-to-market value of our derivatives position related to improved forward pricing across all commodities, along with a $745 million increase in various payables and the reclassification of long-term debt to short-term debt of $206 million. Additionally, other current liabilities at December 31, 2021 increased $55 million, compared to December 31, 2020, primarily due to the assumption of $47 million in liabilities related to the Indigo Merger and $8 million in prepayments/collateral received from certain customers. We believe that our existing cash and cash equivalents, our anticipated cash flow from operations and our available credit facility will be sufficient to meet our working capital and operational spending requirements.
Off-Balance Sheet Arrangements
We may enter into off-balance sheet arrangements and transactions that can give rise to material off-balance sheet obligations.  As of December 31, 2021, our material off-balance sheet arrangements and transactions include operating service arrangements and $160 million in letters of credit outstanding against our 2018 credit facility.  There are no other transactions, arrangements or other relationships with unconsolidated entities or other persons that are reasonably likely to materially affect our liquidity or availability of our capital resources.  For more information regarding off-balance sheet arrangements, we refer you to “Contractual Obligations and Contingent Liabilities and Commitments” below for more information on our operating leases.

(1)As of December 31, 2021, we had commitments for demand and similar charges under firm transportation and gathering agreements to guarantee access capacity on natural gas and liquids pipelines and gathering systems.  Of the total $10.5 billion, $872 million related to access capacity on future pipeline and gathering infrastructure projects that still require the granting of regulatory approvals and/or additional construction efforts.  For further information, we refer you to “Operational Commitments and Contingencies” in Note 10 to the consolidated financial statements included in this Annual Report.  This amount also included guarantee obligations of up to $869 million.
Prior to the Indigo Merger, in May 2021, Indigo closed on an agreement to divest its Cotton Valley natural gas and oil properties. Indigo retained certain contractual commitments related to volume commitments associated with natural gas gathering, for which Southwestern will assume the obligation to pay the gathering provider for any unused portion of the volume commitment under the agreement through 2027, depending on the buyer’s actual use. As of December 31, 2021, up to approximately $36 million of these contractual commitments remain (included in the table above), and the Company has recorded a $17 million liability for its portion of the estimated future payments.
Includes firm transportation commitments acquired with the Montage Merger totaling approximately $976 million. These commitments approximate $96 million within the next year, $192 million from 1 to 3 years, $189 million from 3 to 5 years, $270 million from 5 to 8 years and $229 million beyond 8 years.
In the first quarter of 2019, we agreed to purchase firm transportation with pipelines in the Appalachian basin starting in 2021 and running through 2032, with $327 million in total contractual commitments remaining of which the seller has agreed to reimburse $100 million of these commitments.
(2)Interest payments on our senior notes were calculated utilizing the fixed rates associated with our fixed rate notes outstanding at December 31, 2021.  Senior note interest rates were based on our credit ratings as of December 31, 2021.
(3)Operating leases include costs forcompressors, drilling rigs, pressure pumping equipment, office space and other equipment under non-cancelable operating leases expiring through 2036.
(4)As of December 31, 2021, our E&P segment had commitments of approximately $38 million for compression services associated primarily with our Appalachia division.
(5)Our other significant contractual obligations include approximately $10 million for various information technology support and data subscription agreements.
Future contributions to the pension and postretirement benefit plans are excluded from the table above.  For further information regarding our pension and other postretirement benefit plans, we refer you to Note 13 to the consolidated financial statements included in this Annual Report and “Critical Accounting Policies and Estimates” below for additional information.
We refer you to Note 9 to the consolidated financial statements included in this Annual Report for a discussion of the terms of our debt.  
We are subject to various litigation, claims and proceedings that arise in the ordinary course of business, such as for alleged breaches of contract, miscalculation of royalties, employment matters, traffic incidents, pollution, contamination, encroachment on others’ property or nuisance.  We accrue for such items when a liability is both probable and the amount can be reasonably estimated. Management believes that current litigation, claims and proceedings, individually or in aggregate and after taking into account insurance, are not likely to have a material adverse impact on our financial position, results of operations andor cash flows, although it is possible that adverse outcomes could have a material adverse effect on our results of operations or cash flows for the periodsperiod in which the effect of that outcome becomes reasonably estimable.  Many of these matters are in early stages, so the allegations and the damage theories have not been fully developed, and are all subject to inherent uncertainties; therefore, management’s view may change in the future.
We are also subject to laws and regulations relating to the protection of the environment.  Environmental and cleanup related costs of a non-capital nature are accrued when it is both probable that a liability has been incurred and when the amount can be

Supplemental Guarantor Financial Information
As discussed in Note 9, in April 2018 the Company entered into the 2018 credit facility. Pursuant to requirements under the indentures governing our senior notes, each 100% owned subsidiary that became a guarantor of the 2018 credit facility also became a guarantor of each of our senior notes (the “Guarantor Subsidiaries”). The Guarantor Subsidiaries also granted liens and security interests to support their guarantees under the 2018 credit facility but not of the senior notes. These guarantees are full and unconditional and joint and several among the Guarantor Subsidiaries. Certain of our operating units which are accounted for on a consolidated basis do not guarantee the 2018 credit facility and senior notes.
Upon the closing of the Mergers, discussed further in Note 2 to the consolidated financials included in this Annual Report, certain acquired entities owning oil and gas properties became guarantors to the 2018 credit facility.
The Company and the Guarantor Subsidiaries jointly and severally, and fully and unconditionally, guarantee the payment of the principal and premium, if any, and interest on the senior notes when due, whether at stated maturity of the senior notes, by acceleration, by call for redemption or otherwise, together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Company to the holders of the senior notes.

SEC Regulation S-X Rule 13-01 requires the presentation of “Summarized Financial Information” to replace the “Condensed Consolidating Financial Information” required under Rule 3-10. Rule 13-01 allows the omission of Summarized Financial Information if assets, liabilities and results of operations of the Guarantors are not materially different than the corresponding amounts presented in the consolidated financial statements of the Company. The Parent and Guarantor Subsidiaries comprise the material operations of the Company. Therefore, the Company concluded that the presentation of the Summarized Financial Information is not required as the Summarized Financial Information of the Company’s Guarantors is not materially different from our consolidated financial statements.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
The discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”).States.  The preparation of these financial statements in accordance with GAAP requires management to make estimates and assumptionsjudgments that affect the amounts of assets, liabilities, revenues and liabilitiesexpenses and related disclosure of contingent assets and liabilities, if any, atliabilities.  We evaluate our estimates on an on-going basis, based on historical experience and on various other assumptions that are believed to be reasonable under the date of the financial statements, and the amounts of revenues and expenses during the reporting period.circumstances.  Actual results couldmay differ from those estimates.  The Company evaluates subsequent events throughthese estimates under different assumptions or conditions.  We believe the datefollowing describes significant judgments and estimates used in the financial statements are issued.
Principlespreparation of Consolidation
Theour consolidated financial statements include the accounts of Southwestern and its wholly-owned subsidiaries.  All significant intercompany accounts and transactions have been eliminated.statements.
In 2015, the Company purchased an 86% ownership in a limited partnership that owns and operates a gathering system in Northeast Appalachia.  Because the Company owns a controlling interest in the partnership, the operating and financial results are consolidated with the Company’s E&P segment results.  The minority partner’s share of the partnership activity is reported in retained earnings in the consolidated financial statements.  Net income attributable to noncontrolling interest for the years ended December 31, 2019, 2018 and 2017 was insignificant.
Major Customers
The Company sells the vast majority of its E&P natural gas, oil and NGL production to third-party customers through its marketing subsidiary.  In 2019, 0 single customer accounted for 10% or greater of total sales.  For the years ended December 31, 2018 and 2017, 2 subsidiaries of Royal Dutch Shell Plc in aggregate accounted for approximately 10.4% and 10.3%, respectively, of total natural gas, oil and NGL sales.  The Company believes that the loss of a major customer would not have a material adverse effect on its ability to sell its natural gas, oil and NGL production because alternative purchasers are available.
Cash and Cash Equivalents
Cash and cash equivalents are defined by the Company as short-term, highly liquid investments that have an original maturity of three months or less and deposits in money market mutual funds that are readily convertible into cash.  Management considers cash and cash equivalents to have minimal credit and market risk as the Company monitors the credit status of the financial

Property, Depreciation, Depletion and Amortization
Natural Gas and Oil Properties.  The Company utilizes
We utilize the full cost method of accounting for costs related to the exploration, development and acquisition of natural gas and oil properties.  Under this method, all such costs (productive and nonproductive), including salaries, benefits and other internal costs directly attributable to these activities, are capitalized on a country-by-country basis and amortized over the estimated lives of the properties using the units-of-production method.  These capitalized costs are subject to a quarterly ceiling test that limits such pooled costs, net of applicable deferred taxes, to the aggregate of the present value of future net revenues attributable to proved natural gas, oil and NGL reserves discounted at 10% (standardized measure). plus the lower of cost or market value of unproved properties.  Any costs in excess of the ceiling are written off as a non-cash expense.  The expense may not be reversed in future periods, even though higher natural gas, oil and NGL prices may subsequently increase the ceiling.  Companies using the full cost method are required to use the average quoted price from the first day of each month from the previous 12 months, including the impact of derivatives designated for hedge accounting, to calculate the ceiling value of their reserves. DecreasesPrices used to calculate the ceiling value of reserves were as follows:

Using the average quoted prices above, adjusted for market differentials, our net book value of our United States natural gas and oil properties did not exceed the ceiling amount at December 31, 2021. We had no derivative positions that were designated for hedge accounting as of December 31, 2021.  Future decreases in market prices, as well as changes in production rates, levels of reserves, evaluation of costs excluded from amortization, future development costs and production costs couldmay result in future non-cash impairments to our natural gas and oil properties.
The net book value of our natural gas and oil properties exceeded the ceiling amount in each quarter of 2020 resulting in a total non-cash full cost ceiling test impairments.impairment of $2,825 million.  We had no derivative positions that were designated for hedge accounting as of December 31, 2020.
No impairment expense was recorded in 2020 or 2021 in relation to our natural gas and oil properties acquired from Montage. These properties were recorded at fair value as of November 13, 2020, in accordance with ASC Topic 820 – Fair Value Measurement. In the fourth quarter of 2020, pursuant to SEC guidance, we determined that the fair value of the properties acquired at the closing of the Montage Merger clearly exceeded the related full-cost ceiling limitation beyond a reasonable doubt and received a waiver from the SEC to exclude the properties acquired in the Montage Merger from the ceiling test calculation. This waiver was granted for all reporting periods through and including the quarter ending September 30, 2021, as long as we could continue to demonstrate that the fair value of properties acquired clearly exceeded the full cost ceiling limitation beyond a reasonable doubt in each reporting period. As part of the waiver received from the SEC, we were required to disclose what the full cost ceiling test impairment amounts for all periods presented in each applicable quarterly and annual filing would have been if the waiver had not been granted. The fair value of the properties acquired in the Montage Merger was based on future commodity market pricing for natural gas and oil pricing existing at the date of the Montage Merger, and we affirmed that there has not been a material decline to the fair value of these acquired assets since the Montage Merger. The properties acquired in the Montage Merger had an unamortized cost at December 31, 2020 of $1,087 million. Had we not received the waiver from the SEC, the impairment charge recorded would have been an additional $539 million for the year ended December 31, 2020. Due to the improvement in commodity prices during 2021, no impairment charge would have been recorded in 2021 had the Montage natural gas and oil properties been included in the full cost ceiling test.
Changes in natural gas, oil and NGL prices used to calculate the discounted future net revenues of our reserves affects both the present value of cash flows and the quantity of reserves.  Our reserve base as of December 31, 2021 was approximately 82% natural gas, 2% NGLs and 16% oil, and our standardized measure and reserve quantities as of December 31, 2021, were $18.73 billion and 21.1 Tcfe, respectively.
Costs associated with unevaluated properties are excluded from theour amortization base until we have evaluated the properties are evaluated or impairment is indicated.  The costs associated with unevaluated leasehold acreage and related seismic data, wells currently drilling and related capitalized interest are initially excluded from theour amortization base.  Leasehold costs are either transferred to theour amortization base with the costs of drilling a well on the lease or are assessed at least annually for possible impairment or reduction in value.  The Company’sOur decision to withhold costs from amortization and the timing of the transfer of those costs into the amortization base involves judgment and may be subject to changes over time based on several factors, including our drilling plans, availability of capital, project economics and drilling results from adjacent acreage.  At December 31, 2019, the Company2021, we had a total of $1,506approximately $2,231 million of costs excluded from theour amortization base, all of which related to itsour properties in the United States.  Inclusion of some or all of these costs in our properties in the Company’s United States properties in the future, without adding any associated reserves, could result in additional non-cash ceiling test impairments.
AtProved natural gas, oil and NGL reserves are a major component of the full cost ceiling test. Natural gas, oil and NGL reserves cannot be measured exactly.  Our estimate of natural gas, oil and NGL reserves requires extensive judgments of reservoir engineering data and projections of costs that will be incurred in developing and producing reserves and is generally less precise than other estimates made in connection with financial disclosures.  Our reservoir engineers prepare our reserve estimates under the supervision of our management.  Reserve estimates are prepared for each of our properties annually by the reservoir engineers assigned to the asset management team for that property.  The reservoir engineering and financial data included in these estimates are reviewed by senior engineers, who are not part of the asset management teams, and by our Director of Reserves, who is the technical person primarily responsible for overseeing the preparation of our reserves estimates. Our Director of Reserves has more than 27 years of experience in petroleum engineering, including the estimation of natural gas and oil reserves, and holds a Bachelor of Science in Petroleum Engineering.  Prior to joining us in 2018, our Director of Reserves served in various reservoir engineering roles for EP Energy Company, El Paso Corporation, Cabot Oil & Gas Corporation, Schlumberger and H.J. Gruy & Associates, and is a member of the Society of Petroleum Engineers.  He reports to our Executive Vice President and Chief Operating Officer, who has more than 33 years of experience in petroleum engineering including the estimation of natural gas, oil and NGL reserves in multiple basins in the United States, and holds a Bachelor of Science in Petroleum Engineering.  Prior to joining Southwestern in 2017, our Chief Operating Officer served in various engineering and leadership roles for EP Energy

We engage NSAI, a worldwide leader of petroleum property analysis for industry and financial organizations and government agencies, to independently audit our proved reserves estimates as discussed in more detail below.  NSAI was founded in 1961 and performs consulting petroleum engineering services under Texas Board of Professional Engineers Registration No. F-002699. Within NSAI, the two technical persons primarily responsible for auditing our proved reserves estimates (1) have over 24 years and over 20 years of practical experience in petroleum geosciences and petroleum engineering, respectively; (2) have over 13 years and over 20 years of experience in the estimation and evaluation of reserves, respectively; (3) each has a college degree; (4) each is a Licensed Professional Geoscientist in the State of Texas or a Licensed Professional Engineer in the State of Texas; (5) each meets or exceeds the education, training, and experience requirements set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers; and (6) each is proficient in judiciously applying industry standard practices to engineering and geoscience evaluations as well as applying SEC and other industry reserves definitions and guidelines. The financial data included in the reserve estimates is also separately reviewed by our accounting staff. Our proved reserves estimates, as internally reviewed and audited by NSAI, are submitted for review and approval to our President and Chief Executive Officer.  Finally, upon his approval, NSAI reports the results of its reserve audit to the Board of Directors, with whom final authority over the estimates of our proved reserves rests.  A copy of NSAI’s report has been filed as Exhibit 99.1 to this Annual Report. 
Proved developed reserves generally have a higher degree of accuracy in this estimation process, when compared to proved undeveloped and proved non-producing reserves, as production history and pressure data over time is available for the majority of our proved developed properties.  Proved developed reserves accounted for 54% of our total reserve base as of December 31, 2019, using2021.  Assigning monetary values to such estimates does not reduce the average quoted price fromsubjectivity and changing nature of such reserve estimates.  The uncertainties inherent in the first dayreserve estimates are compounded by applying additional estimates of each month from the previous 12 months for Henry Hubrates and timing of future production volumes and the costs that will be incurred in developing and producing the reserves.  We cannot assure you that our internal controls sufficiently address the numerous uncertainties and risks that are inherent in estimating quantities of natural gas, oil and NGL reserves and projecting future rates of $2.58 per MMBtu, West Texas Intermediateproduction and timing of development expenditures as many factors are beyond our control.  We refer you to “Our proved natural gas, oil of $55.69 per barrel and NGLs of $11.58 per barrel, adjusted for market differentials,NGL reserves are estimates that include uncertainties.  Any material changes to these uncertainties or underlying assumptions could cause the Company’squantities and net bookpresent value of our reserves to be overstated or understated” in Item 1A, “Risk Factors,” of Part I of this Annual Report for a more detailed discussion of these uncertainties, risks and other factors.
In conducting its United Statesaudit, the engineers and geologists of NSAI study our major properties in detail and independently develop reserve estimates.  NSAI's audit consists primarily of substantive testing, which includes a detailed review of all operated proved developed properties plus all proved undeveloped locations. The proved developed properties included in the NSAI audit account for approximately 99% of the proved developed reserve volume and 99% of the proved developed present worth as of December 31, 2021. The proved undeveloped properties included in the NSAI audit account for 100% of the proved undeveloped reserve volume and 100% of the proved undeveloped present worth as of December 31, 2021.  In the conduct of its audit, NSAI did not independently verify the data we provided to them with respect to ownership interests, natural gas, oil and NGL production, well test data, historical costs of operation and development, product prices, or any agreements relating to current and future operations of the properties and sales of production.  NSAI has advised us that if, in the course of its audit, something came to its attention that brought into question the validity or sufficiency of any such information or data, NSAI did not rely on such information or data until it had satisfactorily resolved any questions relating thereto or had independently verified such information or data.  On January 28, 2022, NSAI issued its audit opinion as to the reasonableness of our reserve estimates for the year-ended December 31, 2021 stating that our estimated proved natural gas, oil and NGL reserves are, in the aggregate, reasonable and have been prepared in accordance with Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers.
Business Combinations
We account for business combinations under the acquisition method of accounting. Accordingly, we recognize amounts for identifiable assets acquired and liabilities assumed equal to their estimated acquisition date fair values. We make various assumptions in estimating the fair values of assets acquired and liabilities assumed. As fair value is a market-based measurement, it is determined based on the assumptions that market participants would use. The most significant assumptions relate to the estimated fair values of proved and unproved oil and natural gas properties. Fair value of proved natural gas and oil properties as of the acquisition date was $218 million belowbased on estimated proved natural gas, oil and NGL reserves and related discounted net cash flows. Significant inputs to the ceilingvaluation include estimates of future production volumes, future operating and development costs, future commodity prices and a weighted average cost of capital rate. The market-based weighted average cost of capital rate is subjected to additional project-specific risking factors. In addition, when appropriate, we review comparable purchases and sales of natural
74

gas and oil properties within the same regions, and use that data as a proxy for fair market value as this is an indication of the amount that a willing buyer and therefore did not resultseller would enter into in exchange for such properties. Any excess of the acquisition price over the estimated fair value of net assets acquired is recorded as goodwill. Any excess of the estimated fair value of net assets acquired over the acquisition price is recorded in current earnings as a ceiling test impairmentgain on bargain purchase. Deferred taxes are recorded for any differences between the assigned values and the tax basis of assets and liabilities.

The Mergers qualified as business combinations, and as such, we estimated the fair values of the assets acquired and liabilities assumed as of respective acquisition dates. The fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Fair value measurements also utilize assumptions of market participants. We used discounted cash flow models and we made market assumptions as to future commodity prices, projections of estimated quantities of natural gas and oil reserves, expectations for timing and amount of future development and operating costs, projections of future rates of production, expected recovery rates and risk adjusted discount rates. These assumptions represent Level 3 inputs, as defined in Note 8 – Fair Value Measurements.
We recorded the net assets acquired and liabilities assumed in the Montage Merger at their estimated fair value on November 13, 2020 of approximately $213 million.
We recorded the net assets acquired and liabilities assumed in the Indigo Merger at their estimated fair value on September 1, 2021 of approximately $1,961 million.
We recorded the net assets acquired and liabilities assumed in the GEPH Merger at their estimated fair value on December 31, 2019. Given2021 of approximately $1,732 million.
We consider the fallestimated fair values above to be representative of the prices paid by typical market participants. These measurements resulted in commodityno goodwill or bargain purchases being recognized.
Derivatives and Risk Management
We use fixed price swap agreements and options to reduce the volatility of earnings and cash flow due to fluctuations in the prices of certain commodities and interest rates.  Our policies prohibit speculation with derivatives and limit agreements to counterparties with appropriate credit standings to minimize the risk of uncollectability.  We actively monitor the credit status of our counterparties based on their credit ratings and credit default swap rates where applicable, and to date have not had any credit defaults associated with our transactions.  In both 2021 and 2020, we financially protected 83% of our total production with derivatives.  The primary risks related to our derivative contracts are the volatility in 2019market prices and early 2020,basis differentials for our production.  However, the Company expects some non-cash impairmentmarket price risk is generally offset by the gain or loss recognized upon the related transaction that is financially protected.
All derivatives are recognized in the balance sheet as either an asset or a liability as measured at fair value other than transactions for which the normal purchase/normal sale exception is applied.  Certain criteria must be satisfied for derivative financial instruments to be designated for hedge accounting. Accounting guidance for qualifying hedges allows an unsettled derivative’s unrealized gains and losses to be recorded in either earnings or as a component of its assets will likely occurother comprehensive income until settled.  In the period of settlement, we recognize the gains and losses from these qualifying hedges in gas sales revenues.  The ineffective portion of those fixed price swaps are recognized in earnings.  Gains and losses on derivatives that are not designated for hedge accounting treatment, or that do not meet hedge accounting requirements, are recorded as earlya component of gain (loss) on derivatives on the consolidated statements of operations. Accordingly, the gain (loss) on derivatives component of the statement of operations reflects the gains and losses on both settled and unsettled derivatives.  We calculate gains and losses on settled derivatives as the first quartersummation of 2020. The Company had 0gains and losses on positions which have settled within the reporting period.
As of December 31, 2021, none of our derivative positions thatcontracts were designated for hedge accounting treatment.  Changes in the fair value of unsettled derivatives that were not designated for hedge accounting treatment are recorded in gain (loss) on derivatives.  See Note 6 to the consolidated financial statements included in this Annual Report for more information on our derivative position at December 31, 2021.
Future market price volatility could create significant changes to the derivative positions recorded in our consolidated financial statements.  We refer you to “Quantitative and Qualitative Disclosures about Market Risk” in Item 7A of Part II of this Annual Report for additional information regarding our hedging activities.
Pension and Other Postretirement Benefits
As part of ongoing effort to reduce costs, we have elected to freeze our pension plan effective January 1, 2021. Employees that were participants in the pension plan prior to January 1, 2021 will continue to receive the interest component of the plan but
75

Table of Contents
Index to Financial Statements
will no longer receive the service component. We have commenced the pension plan termination process, but the specific date for the completion of the process is unknown at this time and will depend on certain legal and regulatory requirements or approvals. As part of the termination process, we expect to distribute lump sum payments to or purchase annuities for the benefit of plan participants, which is dependent on the participants’ elections. In addition, we expect to make a payment equal to the difference between the total benefits due under the plan and the total value of the assets available, which, as of December 31, 2019.2021, was approximately $12 million. Our current funding policy is to continue to contribute amounts which are actuarially determined to provide the plan with sufficient assets to meet future benefit payment requirements and which are tax deductible. We are in the process of evaluating the impact of the termination and future settlement accounting on our consolidated financial statements and related disclosures.
We record our prepaid or accrued benefit cost, as well as our periodic benefit cost, for our pension and other postretirement benefit plans using measurement assumptions that we consider reasonable at the time of calculation (see Note 13 to the consolidated financial statements included in this Annual Report for further discussion and disclosures regarding these benefit plans).  Two of the assumptions that affect the amounts recorded are the discount rate, which estimates the rate at which benefits could be effectively settled, and the expected return on plan assets, which reflects the average rate of earnings expected on the funds invested.  For the December 31, 2021 benefit obligation the initial discount rate assumed is 3.20%.  This compares to an initial discount rate of 3.10% for the benefit obligation and periodic benefit cost recorded in 2021.  For the 2022 periodic benefit cost, the expected return assumed was reduced from 5.10% to 0.10%, as the investment allocations have shifted from a balanced portfolio to short-term fixed-income assets in alignment with the plan termination process. Using the average quotedassumed rates discussed above, we recorded total benefit cost of $4 million in 2021 related to our pension and other postretirement benefit plans, which included a $2 million settlement adjustment.
As of December 31, 2021, we recognized a liability of $25 million, compared to $46 million at December 31, 2020, related to our pension and other postretirement benefit plans.  During 2021, we made cash contributions totaling $12 million to fund our pension and other postretirement benefit plans.
Long-term Incentive Compensation
Our long-term incentive compensation plans consist of a combination of stock-based awards that derive their value directly or indirectly from our common stock price, fromand cash-based awards that are fixed in amount, but subject to meeting annual performance thresholds. In March 2020, we issued our first long-term fixed cash-based awards.
We account for long-term incentive compensation transactions using a fair value method and recognize an amount equal to the first day of each month from the previous 12 months for Henry Hub natural gas of $3.10 per MMBtu, West Texas Intermediate oil of $65.56 per barrel and NGLs of $17.64 per barrel, adjusted for market differentials, the Company’s net bookfair value of its United Statesthe stock-based awards and cash-based awards cost in either the consolidated statement of operations or capitalize the cost into natural gas and oil properties didincluded in property and equipment.  Costs are capitalized when they are directly related to the acquisition, exploration and development activities of our natural gas and oil properties.  We use models to determine fair value of stock-based compensation, which requires significant judgment with respect to forfeitures, volatility and other factors. The performance cash awards granted in 2021 and 2020 include a performance condition determined annually by the Company. If we, in our sole discretion, determine that the threshold was not exceedmet, the ceiling amount for that vesting period will not vest and did notwill be cancelled.
Our stock-based compensation is classified as either an equity award or a liability award in accordance with generally accepted accounting principles.  The fair value of an equity-classified award is determined at the grant date and is amortized on a straight-line basis over the vesting life of the award.  The fair-value of a liability-classified award is determined on a quarterly basis through the final vesting date and is amortized based on the current fair value of the award and the percentage of vesting period incurred to date. See Note 14 to the consolidated financial statements included in this Annual Report for further discussion and disclosures regarding our long-term incentive compensation.
New Accounting Standards
Refer to Note 1 to the consolidated financial statements included in this Annual Report for further discussion of our significant accounting policies and for discussion of accounting standards that have been implemented in this report, along with a discussion of relevant accounting standards that are pending adoption.
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market risks relating to our operations result primarily from the volatility in a ceiling test impairment atcommodity prices, basis differentials and interest rates, as well as service costs and credit risk concentrations.  We use fixed price swap agreements, options, swaptions, basis swaps and interest rate swaps to reduce the volatility of earnings and cash flow due to fluctuations in the prices of natural gas, oil and certain NGLs along with interest rates.  Our Board of Directors has approved risk management policies and procedures to utilize financial products for the reduction of defined commodity price risk.  Utilization of financial products for the reduction of interest

rate risks is also overseen by our Board of Directors.  These policies prohibit speculation with derivatives and limit swap agreements to counterparties with appropriate credit standings.
Credit Risk
Our exposure to concentrations of credit risk consists primarily of trade receivables and derivative contracts associated with commodities trading.  Concentrations of credit risk with respect to receivables are limited due to the large number of our purchasers and their dispersion across geographic areas.  For the year ended December 31, 2018.  2021, one purchaser accounted for 12% of our revenues. If we had completed the Indigo Merger and the GEPH Merger at the beginning of 2021, this same purchaser would have accounted for approximately 16% of our revenues. A default on this account could have a material impact on the Company.  For the year ended December 31, 2020, one purchaser accounted for 10% of our revenues.  See “Commodities Risk” below for discussion of credit risk associated with commodities trading.
Interest Rate Risk
As of December 31, 2021, we had approximately $4.4 billion of outstanding senior notes with a weighted average interest rate of 5.68%, $550 million of borrowings under our Term Loan facility and $460 million of borrowings under our 2018 credit facility.  We currently have an interest rate swap in effect to mitigate a portion of our exposure to volatility in interest rates.  At December 31, 2021, we had long-term debt issuer ratings of Ba2 by Moody’s, BB by S&P and BB by Fitch Ratings.  On September 1, 2021, S&P upgraded our bond rating to BB, and on January 6, 2022, S&P further upgraded our bond rating to BB+, which will have the effect of decreasing the interest rate on the 2025 notes to 5.95%, beginning with coupon payments paid after January 2022. Any further upgrades or downgrades in our public debt ratings by Moody’s or S&P could decrease or increase our cost of funds, respectively.

Commodities Risk
We use fixed price swap agreements and options to protect sales of our production against the inherent risks of adverse price fluctuations or locational pricing differences between a published index and the NYMEX futures market.  These swaps and options include transactions in which one party will pay a fixed price (or variable price) for a notional quantity in exchange for receiving a variable price (or fixed price) based on a published index (referred to as price swaps) and transactions in which parties agree to pay a price based on two different indices (referred to as basis swaps).
The primary market risks relating to our derivative contracts are the volatility in market prices and basis differentials for our production.  However, the market price risk is offset by the gain or loss recognized upon the related sale or purchase of the production that is financially protected. Credit risk relates to the risk of loss as a result of non-performance by our counterparties. The counterparties are primarily major banks and integrated energy companies that management believes present minimal credit risks. The credit quality of each counterparty and the level of financial exposure we have to each counterparty are closely monitored to limit our credit risk exposure. Additionally, we perform both quantitative and qualitative assessments of these counterparties based on their credit ratings and credit default swap rates where applicable. We have not incurred any counterparty losses related to non-performance and do not anticipate any losses given the information we have currently. However, we cannot be certain that we will not experience such losses in the future.  The fair value of our derivative assets and liabilities includes a non-performance risk factor. We refer you to Note 6 and Note 8 of the consolidated financial statements included in this Annual Report for additional details about our derivative instruments and their fair value.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders of Southwestern Energy Company
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Southwestern Energy Company and its subsidiaries (the “Company”) as of December 31, 2021 and 2020, and the related consolidated statements of operations, of comprehensive income (loss), of changes in equity and of cash flows for each of the three years in the period ended December 31, 2021, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that

Table of Contents
Index to Financial Statements
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the first daycurrent period audit of each month from the previous 12 months for Henry Hub natural gasconsolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of $2.98 per MMBtu, West Texas Intermediate oilcritical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
The Impact of $47.79 per barrelProved Natural Gas, Oil and NGLs of $14.41 per barrel, adjusted for market differentials,NGL Reserves on Natural Gas and Oil Properties
As described in Note 1 to the consolidated financial statements, the Company’s net book value of its United Statesconsolidated natural gas and oil properties did not exceed the ceiling amount and did not results in a ceiling test impairment at December 31, 2017.  The Company had 0 derivative positions that were designated for hedge accountingbalance was $33,631 million as of December 31, 2017.2021, and depreciation, depletion and amortization expense for the year ended December 31, 2021 was $546 million. The Company utilizes the full cost method of accounting for its natural gas and oil properties. Under this method, all capitalized costs are amortized over the estimated lives of the properties using the unit-of-production method based on proved natural gas, oil and natural gas liquids (NGL) reserves. These capitalized costs are subject to a ceiling test that limits such pooled costs, net of applicable deferred taxes, to the aggregate of the present value of future net revenues attributable to proved natural gas, oil and NGL reserves discounted at 10%. As disclosed by management, proved natural gas, oil and NGL reserves are a major component of the full cost ceiling test. Estimates of reserves require extensive judgments of reservoir engineering data and projections of costs that will be incurred in developing and producing reserves. The uncertainties inherent in the reserve estimates are compounded by applying additional estimates of the rates and timing of future production volumes and the costs that will be incurred in developing and producing the reserves. The estimates of natural gas, oil and NGL reserves have been developed by specialists, specifically reservoir engineers, and audited by independent petroleum engineers (together referred to as “specialists”).
The principal considerations for our determination that performing procedures relating to the impact of proved natural gas, oil and NGL reserves on natural gas and oil properties is a critical audit matter are (i) the significant judgment by management, including the use of management’s specialists, when developing the estimates of proved natural gas, oil and NGL reserves, which in turn led to (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating audit evidence related to the data, methods, and assumptions used by management and its specialists in developing the estimates of proved natural gas, oil and NGL reserves and the assumption applied to the full cost ceiling test related to future production volumes.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s estimates of proved natural gas, oil and NGL reserves and the full cost ceiling test calculation. The work of management’s specialists was used in performing the procedures to evaluate the reasonableness of the estimates of proved natural gas, oil and NGL reserves and the reasonableness of future production volumes applied in the full cost ceiling test. As a basis for using this work, specialists’ qualifications were understood and the Company’s relationship with the specialists was assessed. The procedures performed also included evaluation of the methods and assumptions used by specialists, tests of the completeness and accuracy of the data used by the specialists, and an evaluation of specialists’ findings.
Acquisitions of Indigo Natural Resources LLC and GEP Haynesville, LLC – Valuation of Proved Natural Gas and Oil Properties
As described in Note 2 to the consolidated financial statements, the Company completed the acquisitions of Indigo Natural Resources LLC and GEP Haynesville, LLC for net consideration of $1,961 million and $1,732 million, respectively, which resulted in $4,507 million of proved natural gas and oil properties being recorded from these acquisitions. As disclosed by management, the Company accounts for business combinations under the acquisition method of accounting. Accordingly, the Company recognizes amounts for identifiable assets acquired and liabilities assumed equal to their estimated acquisition date fair

Gathering Systems.values. The Company’s investment in gathering systems was primarily in a system serving its Fayetteville Shale operations in Arkansas.  These assets were included inmost significant assumptions relate to the Fayetteville Shale sale that closed in December 2018.
Capitalized Interest.  Interest is capitalized on the costestimated fair values of unevaluatedproved natural gas and oil properties. Fair value of proved natural gas and oil properties as of the acquisition date was based on estimated proved natural gas, oil, and NGL reserves and related discounted net cash flows. Significant inputs to the valuation include estimates of future production volumes, future operating and development costs, future commodity prices and a weighted average cost of capital rate. The estimates of natural gas, oil and NGL reserves have been developed by specialists, specifically reservoir engineers, and audited by independent petroleum engineers (together referred to as “specialists”).
The principal considerations for our determination that are excluded from amortization.
Asset Retirement Obligations.  Naturalperforming procedures relating to the valuation of proved natural gas and oil properties require expenditures to plugfrom the acquisitions of Indigo Natural Resources LLC and abandonGEP Haynesville, LLC is a critical audit matter are (i) the wells and reclaim the associated pads and other supporting infrastructure when the wells are no longer producing.  An asset retirement obligation associated with the retirement of a tangible long-lived asset such as oil and gas properties is recognized as a liability in the period incurred or when it becomes determinable, with an associated increase in the carrying amount of the related long-lived asset.  The cost of the tangible asset,significant judgment by management, including the asset retirement cost, is depreciated over the useful lifeuse of the asset.  The asset retirement obligation is recorded at its estimated fair value, and accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value.
Impairment of Long-Lived Assets.  The Company’s non-full cost pool assets include water facilities, gathering systems, technology infrastructure, land, buildings and other equipment with useful lives that range from 3 to 30 years. The carrying value of non-full cost pool long-lived assets is evaluated for recoverability whenever events or changes in circumstances indicate that it may not be recoverable.  Should an impairment exist, the impairment loss would be measured as the amount that the asset’s carrying value exceeds its fair value. For the year ended December 31, 2019, the Company recognized non-cash impairments of $16 million for non-core assets.
In accordance with accounting guidance for Property, Plant and Equipment, assets held for sale are measured at the lower of carrying value or fair value less costs to sell.  This accounting guidance does not apply to the Company’s full cost pool assets, which are governed under SEC Regulation S-X 4-10, and thus were not classified as held for sale.  Because the assets excluding the full cost pool met the criteria for held for sale accounting in the third quarter of 2018 due to their inclusion in the Fayetteville Shale sale, the Company determined the carrying value of certain non-full cost pool assets exceededmanagement’s specialists, when developing the fair value less costsof acquired proved natural gas and oil properties, which in turn led to sell.  As(ii) a result, a non-cash impairment chargehigh degree of $160 million was recorded for the year ended December 31, 2018, of which $145 millionauditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to midstream gathering assets held for salefuture production volumes, future commodity prices, and $15 million related to E&P assets held for sale.  Separately, the Company recorded an $11 million non-cash impairmentweighted average cost of other non-core assets that were not includedcapital rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.
Addressing the matter involved performing procedures and evaluating audit evidence in the Fayetteville Shale sale, for the year ended December 31, 2018.
Intangible Assets.  The carrying value of intangible assets are evaluated for recoverability whenever events or changes in circumstances indicate that it may not be recoverable. Intangible assets are amortized over their useful life. At December 31, 2019 and 2018, the Company had $56 million and $65 million, respectively, in marketing-related intangible assets that were included in Other long-term assetsconnection with forming our overall opinion on the consolidated balance sheets.financial statements. These procedures included testing the effectiveness of controls relating to the valuation of the acquired proved natural gas and oil properties. These procedures also included, among others (i) reading the purchase agreement; (ii) testing management’s process for developing the fair value of acquired proved natural gas and oil properties; (iii) evaluating the appropriateness of the discounted cash flow models; (iv) testing the completeness and accuracy of underlying data used in the discounted cash flow models; and (v) evaluating the reasonableness of significant assumptions used by management related to future production volumes, future commodity prices, and the weighted average cost of capital rate. Evaluating the reasonableness of management’s significant assumption related to future commodity prices involved comparing the future commodity prices against observable market data and evaluating commodity price differentials through inspection of the underlying contracts. Professionals with specialized skill and knowledge were used to assist in evaluating the appropriateness of the discounted cash flow models and the reasonableness of the weighted average cost of capital rate significant assumption. The Company amortized $9work of management’s specialists was used in performing the procedures to evaluate the reasonableness of the proved natural gas and oil reserves as stated in the Critical Audit Matter titled “Impact of Proved Natural Gas, Oil and NGL Reserves on Natural Gas and Oil Properties” and the reasonableness of the future production volumes. As a basis for using this work, the specialists’ qualifications were understood and the Company’s relationship with the specialists was assessed. The procedures performed also included evaluation of the methods and assumptions used by the specialists, tests of the completeness and accuracy of the data used by the specialists, and an evaluation of the specialists’ findings.

Income tax expense (benefit)$— $407 
Effective tax rate%(15)%
In 2020, due to significant pricing declines and the material write-down of the carrying value of our natural gas and oil properties in addition to other negative evidence, management concluded that it was more likely than not that a portion of our deferred tax assets would not be realized and recorded a valuation allowance. As of December 31, 2021, we still maintain a full valuation allowance. We also retained a valuation allowance of $59 million related to net operating losses in jurisdictions in which we no longer operate. Management will continue to assess available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit the use of deferred tax assets. The amount of the deferred tax asset considered realizable, however, could be adjusted based on changes in subjective estimates of future taxable income or if objective negative evidence is no longer present.
Due to the issuance of common stock associated with the Indigo Merger, as discussed in Note 2 to the consolidated financial statements to this Annual Report, we incurred a cumulative ownership change and as such, our net operating losses (“NOLs”) prior to the acquisition are subject to an annual limitation under Internal Revenue Code Section 382 of approximately $48 million. The ownership changes and resulting annual limitation will result in the expiration of NOLs or other tax attributes otherwise available, with a corresponding decrease in our valuation allowance. At December 31, 2021, we had approximately $4 billion of federal NOL carryovers, of which approximately $3 billion have an expiration date between 2035 and 2037 and $1 billion have an indefinite carryforward life. We currently estimate that approximately $2 billion of these federal NOLs will expire before they are able to be used. The non-expiring NOLs remain subject to a full valuation allowance. If a subsequent ownership change were to occur as a result of future transactions in our common stock, our use of remaining U.S. tax attributes may be further limited.
We refer you to Note 11 to the consolidated financial statements included in this Annual Report for additional discussion about our income taxes.
LIQUIDITY AND CAPITAL RESOURCES
We depend primarily on funds generated from our operations, our 2018 credit facility, our cash and cash equivalents balance and capital markets as our primary sources of liquidity.  In October 2021, the banks participating in our 2018 credit facility reaffirmed our elected borrowing base and aggregate commitments to be $2.0 billion. At December 31, 2021, we had approximately $1.4 billion of total available liquidity, which exceeds our currently modeled needs as we remain committed to our strategy of capital discipline.
In November 2021 in conjunction with the GEPH Merger, we amended our 2018 credit facility agreement to permit access to additional secured debt capacity in the form of a term loan for incremental capital up to $900 million, ranking equally with our 2018 credit facility. In December 2021, we raised $550 million in term loan financing to partially fund the GEPH Merger, with no impact to our liquidity at year end. The remaining $350 million of incremental term loan capacity remains accessible through November 2022 and provides access to another secured debt capital source for liquidity purposes.
Our flexibility to access incremental secured debt capital is derived from our excess asset collateral value above the elected $2.0 billion borrowing base and aggregate commitments of our 2018 credit facility. Our ability to issue secured debt is governed by the limitations of our 2018 credit facility as well as our secured debt capacity (as defined by our senior note indentures) which was $3.7 billion as of December 31, 2021, based on 25% of adjusted consolidated net tangible assets.
Looking forward in 2022, we expect to continue to generate free cash flow from operations, net of changes in working capital, in excess of our expected capital investments, and we intend to utilize this free cash flow to pay down our debt. We refer you to Note 9 to the consolidated financial statements included in this Annual Report and the section below under “Credit Arrangements and Financing Activities” for additional discussion of our 2018 credit facility and related covenant requirements.
Our cash flow from operating activities is highly dependent upon our ability to sell and the sales prices that we receive for our natural gas and liquids production.  Natural gas, oil and NGL prices are subject to wide fluctuations and are driven by market supply and demand, which is impacted by many factors.  See "Market Conditions and Commodity Prices" in the Overview section of Item 7 in Part II for additional discussion about current and potential future market conditions. The sales price we receive for our production is also influenced by our commodity derivative program.  Our derivative contracts allow us to ensure a certain level of cash flow to fund our operations.  Although we are continually adding additional derivative positions for portions of our expected 2022, 2023 and 2024 production, there can be no assurance that we will be able to add derivative positions to cover the

remainder of our expected production at favorable prices. See “Risk Factors” in Item 1A, “Quantitative and Qualitative Disclosures about Market Risk” in Item 7A and Note 6 in the consolidated financial statements included in this Annual Report for further details.
Our commodity hedging activities are subject to the credit risk of our counterparties being financially unable to settle the transaction.  We actively monitor the credit status of our counterparties, performing both quantitative and qualitative assessments based on their credit ratings and credit default swap rates where applicable, and to date have not had any credit defaults associated with our transactions.  However, any future failures by one or more counterparties could negatively impact our cash flow from operating activities.
Our short-term cash flows are also dependent on the timely collection of receivables from our customers and joint interest owners.  We actively manage this risk through credit management activities and, through the date of this filing, have not experienced any significant write-offs for non-collectable amounts.  However, any sustained inaccessibility of credit by our customers and joint interest owners could adversely impact our cash flows.
Due to these factors, we are unable to forecast with certainty our future level of cash flow from operations.  Accordingly, we expect to adjust our discretionary uses of cash depending upon available cash flow.  Further, we may from time to time seek to retire, rearrange or amend some or all of our outstanding debt or debt agreements through cash purchases, and/or exchanges, open market purchases, privately negotiated transactions, tender offers or otherwise.  Such transactions, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors.  The amounts involved may be material.
Credit Arrangements and Financing Activities
In April 2018, we entered into a revolving credit facility (the "2018 credit facility") with a group of banks that, as amended, has a maturity date of April 2024.  The 2018 credit facility has an aggregate maximum revolving credit amount of $3.5 billion and, in October 2021, the banks participating in our 2018 credit facility reaffirmed the elected borrowing base to be $2.0 billion, which also reflected our aggregate commitments. The borrowing base is subject to redetermination at least twice a year, which typically occurs in April and October, and is subject to change based primarily on drilling results, commodity prices, our future derivative position, the level of capital investment and operating costs. The 2018 credit facility is secured by substantially all of our assets, including most of our subsidiaries. The permitted lien provisions in certain senior note indentures currently limit liens securing indebtedness to the greater of $2.0 billion or 25% of adjusted consolidated net tangible assets. We may utilize the 2018 credit facility in the form of loans and letters of credit. As of December 31, 2021, we had $460 million of borrowings on our 2018 credit facility and $160 million in outstanding letters of credit. We currently do not anticipate being required to supply a materially greater amount of letters of credit under our existing contracts. We refer you to Note 9 to the consolidated financial statements included in this Annual Report for additional discussion of our 2018 credit facility.
As of December 31, 2021, we were in compliance with all of the applicable covenants contained in the credit agreement governing our 2018 credit facility.  Our ability to comply with financial covenants in future periods depends, among other things, on the success of our development program and upon other factors beyond our control, such as the market demand and prices for natural gas and liquids.  We refer you to Note 9 of the consolidated financial statements included in this Annual Report for additional discussion of the covenant requirements of our 2018 credit facility.
The credit status of the financial institutions participating in our 2018 credit facility could adversely impact our ability to borrow funds under the 2018 credit facility.  Although we believe all of the lenders under the facility have the ability to provide funds, we cannot predict whether each will be able to meet their obligation to us.  We refer you to Note 9 to the consolidated financial statements included in this Annual Report for additional discussion of our 2018 credit facility.
Our exposure to the anticipated transition from LIBOR is limited to the 2018 credit facility. The USD-LIBOR settings are expected to be published through June 2023, and we anticipate using a variation of this rate until the underlying agreements are extended beyond the LIBOR publication date.
Key financing activities for the years ended December 31, 2021 and 2020 are as follows:
Debt and Common Stock Issuance
On December 22, 2021, we completed a public offering of $1,150 million aggregate principal amount of our 4.75% Senior Notes due 2032 (the “2032 Notes”), with net proceeds from the offering totaling $1,133 million after underwriting discounts and offering expenses. The net proceeds were used to fund a portion of the GEPH Merger, which closed on December 31, 2021, and to fund tender offers for $300 million of our 2025 Notes. The remaining proceeds were used for general corporate purposes.

In contemplation of the GEPH Merger, on December 22, 2021, we entered into a term loan credit agreement with a group of lenders that provided for a $550 million secured term loan facility which matures on June 22, 2027 (the “Term Loan”). As of December 31, 2021, we had borrowings under the Term Loan of $550 million. The net proceeds from the initial loans of $542 million were used to fund a portion of the GEPH Merger on December 31, 2021.
On December 31, 2021, we issued 99,337,748 shares of our common stock in conjunction with the GEPH Merger. These shares of our common stock had an aggregate dollar value equal to approximately $463 million, based on the closing price of $4.66 per share of our common stock on the NYSE on December 31, 2021. See Note 2 for additional details on the GEPH Merger.
In November 2021, in contemplation of the GEPH Merger, we amended our 2018 credit facility agreement to permit access to additional secured debt capacity in the form of the previously-described Term Loan for incremental capital up to $900 million, ranking equally with our 2018 credit facility. As of December 31, 2021, we had borrowings under the Term Loan of $550 million, which were used to partially fund the GEPH Merger, and $350 million of incremental term loan capacity, which remains accessible through November 2022.
In August 2021, we completed a public offering of $1,200 million aggregate principal amount of our 5.375% Senior Notes due 2030 (the “2030 Notes”), with net proceeds from the offering totaling $1,183 million after underwriting discounts and offering expenses. The proceeds were used to repurchase the $791 million principal amount of certain of our outstanding senior notes. The remaining proceeds were used to pay borrowings under our 2018 credit facility and for general corporate purposes, including consideration for the Indigo Merger.
In September 2021, we issued 337,827,171 shares of our common stock in conjunction with the Indigo Merger. These shares of our common stock had an aggregate dollar value equal to approximately $1,588 million, based on the closing price of $4.70 per share of our common stock on the NYSE on September 1, 2021. See Note 2 for additional details on the Indigo Merger.
In conjunction with the Indigo Merger and pursuant to the terms of the merger agreement, in September 2021, we assumed $700 million in aggregate principal amount of Indigo’s 5.375% Senior Notes due 2029 (the “Indigo Notes”). Subsequent to the Indigo Merger, we exchanged the Indigo Notes for approximately $700 million of newly issued 5.375% Senior Notes due 2029.
In November 2020, we issued 69,740,848 shares of our common stock in conjunction with the Montage Merger. These shares of our common stock had an aggregate dollar value equal to approximately $213 million, based on the closing price of $3.05 per share of our common stock on the NYSE on November 13, 2020. See Note 2 for additional details on the Montage Merger.
In August 2020, we completed a public offering of $350 million aggregate principal amount of our 2028 Notes, with net proceeds from the offering totaling approximately $345 million after underwriting discounts and offering expenses. The net proceeds were used to fund a portion of the Montage Merger in November 2020.
In August 2020, we completed a public offering of 63,250,000 shares of our common stock with an offering price to the public of $2.50 per share. Net proceeds, after deducting underwriting discounts and offering expenses, were approximately $152 million. The proceeds from the common stock offering, in conjunction with the issuance of the 2028 Notes and additional borrowings on our 2018 credit facility were used to fund a redemption of $510 million aggregate principal amount of Montage’s senior notes in connection with the closing of the Montage Merger.
Debt Repurchases
In 2021, we repurchased $6 million of our 4.10 % Senior Notes due 2022, $467 million of our 4.95% Senior Notes due 2025 and $618 million of our 7.50% Senior Notes due 2026 for $1,177 million in cash, including premiums and fees, and we recognized an additional $7 million in unamortized debt expenses, resulting in a loss on early extinguishment of debt of $93 million.
In 2020, we repurchased $6 million of our 4.10% Senior Notes due 2022, $36 million of our 4.95% Senior Notes due 2025, $21 million of our 7.50% Senior Notes due 2026 and $44 million of our 7.75% Senior Notes due 2027 for $72 million, and recognized a $35 million gain on the extinguishment of debt. We refer you to Note 9 to the consolidated financial statements included in this Annual Report for additional discussion of our senior notes.

In January 2022, we repurchased the remaining outstanding principal balance of $201 million on our 2022 Senior Notes using our 2018 credit facility. As a result of the focused work on refinancing and repayment of our debt in recent years, our outstanding revolver balance and $16 million of our Term Loan principal are the only debt balances scheduled to become due prior to 2025.
At February 25, 2022, we had long-term debt issuer ratings of Ba2 by Moody’s (rating and stable outlook affirmed on November 29, 2021), BB+ by S&P (rating upgraded to BB+ with stable outlook on January 6, 2022) and BB by Fitch Ratings (rating and stable outlook affirmed on November 29, 2021). Effective in July 2018, the interest rate for our 2025 Notes was 6.20%, reflecting a net downgrade in our bond ratings since their issuance. In April 2020, S&P downgraded our bond rating to BB-, which had the effect of increasing the interest rate on the 2025 Notes to 6.45% in July 2020, with the first coupon payment at the higher interest rate in January 2021. On September 1, 2021, S&P upgraded our bond rating to BB, and on January 6, 2022, S&P further upgraded our bond rating to BB+, which will have the effect of decreasing the interest rate on the 2025 Notes to 5.95%, beginning with coupon payments after January 2022. Any further upgrades or downgrades in our public debt ratings by Moody’s or S&P could decrease or increase our cost of funds, respectively.

Net cash provided by operating activities increased 158% or $835 million for the year ended December 31, 2021, compared to the same period in 2020, primarily due to a $2,768 million increase resulting from higher commodity prices, a $524 million increase related to increased production and a $56 million increase in our marketing margin. The increases were partially offset by a $1,854 million decrease in settled derivatives, a $477 million increase in operating costs and expenses, a $132 million decreased impact of working capital and a $42 million increase in interest expense.
Net cash generated from operating activities, net of changes in working capital, exceeded our capital investments by $464 million for the year ended December 31, 2021, compared to providing 67% of our cash requirements for capital investments for the same period in 2020.
Cash Flow from Investing Activities
Total E&P capital investing increased $208 million for the year ended December 31, 2021, compared to the same period in 2020, due to a $191 million increase in direct E&P capital investing, an $8 million increase in capitalized internal costs and a $9 million increase in capitalized interest.  
Capitalized interest increased for the year ended December 31, 2021, as compared to the same period in 2020, as the acquisition of Haynesville unevaluated natural gas and oil properties on September 1, 2021 outpaced the evaluation of our existing unevaluated natural gas and oil properties over the past twelve months. The impact of the addition of additional Haynesville properties from the GEPH Merger on December 31, 2021 is expected to increase the amount of capitalized interest until such time as it is evaluated.
Cash paid in mergers includes cash consideration of $373 million and $1,269 million paid for the Indigo Merger and GEPH Merger, respectively.

In December 2021, we entered into our secured Term Loan facility and, as of December 31, 2021, had borrowings of $550 million outstanding. The net proceeds from the initial loans of $542 million were used to fund a portion of the GEPH Merger on December 31, 2021.
In December 2021, we repaid the outstanding balance of $81 million related to GEPH’s revolving credit facility.
In September 2021, we repaid the outstanding balance of $95 million related to Indigo’s revolving credit facility.
In August 2021, we completed a public offering of $1,200 million aggregate principal amount of our 2030 Notes, with net proceeds from the offering totaling $1,183 million after underwriting discounts and offering expenses. The net proceeds were used to repurchase the $791 million principal amount of certain of our outstanding senior notes. The remaining proceeds were used to pay borrowings under our 2018 credit facility and for general corporate purposes, including consideration for the Indigo Merger.
In November 2020, we paid $522 million to retire the Montage senior notes, and repaid the outstanding balance of $200 million related to Montage’s revolving credit facility.
In August 2020, we completed an underwritten public offering of 63,250,000 shares of our common stock with an offering price to the public of $2.50 per share. Net proceeds after deducting underwriting discounts and offering expenses were approximately $152 million.
In 2020, we repurchased $107 million in aggregate principal amount of our outstanding senior notes at a discount for $72 million and recognized a $35 million gain on the extinguishment of debt.
We refer you to Note 9 to the consolidated financial statements included in this Annual Report for additional discussion of our outstanding debt and credit facility and to Note 1 for additional discussion of our equity offering.
Working Capital
We had negative working capital of $1,639 million at December 31, 2021, a $1,298 million decrease from December 31, 2020, as a $792 million increase in accounts receivable and a $15 million increase in cash were more than offset by $1,092 million reduction in the current mark-to-market value of our derivatives position related to improved forward pricing across all commodities, along with a $745 million increase in various payables and the reclassification of long-term debt to short-term debt of $206 million. Additionally, other current liabilities at December 31, 2021 increased $55 million, compared to December 31, 2020, primarily due to the assumption of $47 million in liabilities related to the Indigo Merger and $8 million in prepayments/collateral received from certain customers. We believe that our existing cash and cash equivalents, our anticipated cash flow from operations and our available credit facility will be sufficient to meet our working capital and operational spending requirements.
Off-Balance Sheet Arrangements
We may enter into off-balance sheet arrangements and transactions that can give rise to material off-balance sheet obligations.  As of December 31, 2021, our material off-balance sheet arrangements and transactions include operating service arrangements and $160 million in letters of credit outstanding against our 2018 credit facility.  There are no other transactions, arrangements or other relationships with unconsolidated entities or other persons that are reasonably likely to materially affect our liquidity or availability of our capital resources.  For more information regarding off-balance sheet arrangements, we refer you to “Contractual Obligations and Contingent Liabilities and Commitments” below for more information on our operating leases.

(1)As of December 31, 2021, we had commitments for demand and similar charges under firm transportation and gathering agreements to guarantee access capacity on natural gas and liquids pipelines and gathering systems.  Of the total $10.5 billion, $872 million related to access capacity on future pipeline and gathering infrastructure projects that still require the granting of regulatory approvals and/or additional construction efforts.  For further information, we refer you to “Operational Commitments and Contingencies” in Note 10 to the consolidated financial statements included in this Annual Report.  This amount also included guarantee obligations of up to $869 million.
Prior to the Indigo Merger, in May 2021, Indigo closed on an agreement to divest its Cotton Valley natural gas and oil properties. Indigo retained certain contractual commitments related to volume commitments associated with natural gas gathering, for which Southwestern will assume the obligation to pay the gathering provider for any unused portion of the volume commitment under the agreement through 2027, depending on the buyer’s actual use. As of December 31, 2021, up to approximately $36 million of these contractual commitments remain (included in the table above), and the Company has recorded a $17 million liability for its portion of the estimated future payments.
Includes firm transportation commitments acquired with the Montage Merger totaling approximately $976 million. These commitments approximate $96 million within the next year, $192 million from 1 to 3 years, $189 million from 3 to 5 years, $270 million from 5 to 8 years and $229 million beyond 8 years.
In the first quarter of 2019, we agreed to purchase firm transportation with pipelines in the Appalachian basin starting in 2021 and running through 2032, with $327 million in total contractual commitments remaining of which the seller has agreed to reimburse $100 million of these commitments.
(2)Interest payments on our senior notes were calculated utilizing the fixed rates associated with our fixed rate notes outstanding at December 31, 2021.  Senior note interest rates were based on our credit ratings as of December 31, 2021.
(3)Operating leases include costs forcompressors, drilling rigs, pressure pumping equipment, office space and other equipment under non-cancelable operating leases expiring through 2036.
(4)As of December 31, 2021, our E&P segment had commitments of approximately $38 million for compression services associated primarily with our Appalachia division.
(5)Our other significant contractual obligations include approximately $10 million for various information technology support and data subscription agreements.
Future contributions to the pension and postretirement benefit plans are excluded from the table above.  For further information regarding our pension and other postretirement benefit plans, we refer you to Note 13 to the consolidated financial statements included in this Annual Report and “Critical Accounting Policies and Estimates” below for additional information.
We refer you to Note 9 to the consolidated financial statements included in this Annual Report for a discussion of the terms of our debt.  
We are subject to various litigation, claims and proceedings that arise in the ordinary course of business, such as for alleged breaches of contract, miscalculation of royalties, employment matters, traffic incidents, pollution, contamination, encroachment on others’ property or nuisance.  We accrue for such items when a liability is both probable and the amount can be reasonably estimated. Management believes that current litigation, claims and proceedings, individually or in aggregate and after taking into account insurance, are not likely to have a material adverse impact on our financial position, results of operations or cash flows, although it is possible that adverse outcomes could have a material adverse effect on our results of operations or cash flows for the period in which the effect of that outcome becomes reasonably estimable.  Many of these matters are in early stages, so the allegations and the damage theories have not been fully developed, and are all subject to inherent uncertainties; therefore, management’s view may change in the future.
We are also subject to laws and regulations relating to the protection of the environment.  Environmental and cleanup related costs of a non-capital nature are accrued when it is both probable that a liability has been incurred and when the amount can be

reasonably estimated.  Management believes any future remediation or other compliance related costs will not have a material effect on our financial position, results of operations or cash flows.
For further information, we refer you to “Litigation” and “Environmental Risk” in Note 10 to the consolidated financial statements included in this Annual Report.
Supplemental Guarantor Financial Information
As discussed in Note 9, in April 2018 the Company entered into the 2018 credit facility. Pursuant to requirements under the indentures governing our senior notes, each 100% owned subsidiary that became a guarantor of the 2018 credit facility also became a guarantor of each of our senior notes (the “Guarantor Subsidiaries”). The Guarantor Subsidiaries also granted liens and security interests to support their guarantees under the 2018 credit facility but not of the senior notes. These guarantees are full and unconditional and joint and several among the Guarantor Subsidiaries. Certain of our operating units which are accounted for on a consolidated basis do not guarantee the 2018 credit facility and senior notes.
Upon the closing of the Mergers, discussed further in Note 2 to the consolidated financials included in this Annual Report, certain acquired entities owning oil and gas properties became guarantors to the 2018 credit facility.
The Company and the Guarantor Subsidiaries jointly and severally, and fully and unconditionally, guarantee the payment of the principal and premium, if any, and interest on the senior notes when due, whether at stated maturity of the senior notes, by acceleration, by call for redemption or otherwise, together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Company to the holders of the senior notes.

SEC Regulation S-X Rule 13-01 requires the presentation of “Summarized Financial Information” to replace the “Condensed Consolidating Financial Information” required under Rule 3-10. Rule 13-01 allows the omission of Summarized Financial Information if assets, liabilities and results of operations of the Guarantors are not materially different than the corresponding amounts presented in the consolidated financial statements of the Company. The Parent and Guarantor Subsidiaries comprise the material operations of the Company. Therefore, the Company concluded that the presentation of the Summarized Financial Information is not required as the Summarized Financial Information of the Company’s Guarantors is not materially different from our consolidated financial statements.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
The discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States.  The preparation of these financial statements requires management to make estimates and judgments that affect the amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities.  We evaluate our estimates on an on-going basis, based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances.  Actual results may differ from these estimates under different assumptions or conditions.  We believe the following describes significant judgments and estimates used in the preparation of our consolidated financial statements.
Natural Gas and Oil Properties
We utilize the full cost method of accounting for costs related to the exploration, development and acquisition of natural gas and oil properties.  Under this method, all such costs (productive and nonproductive), including salaries, benefits and other internal costs directly attributable to these activities, are capitalized on a country-by-country basis and amortized over the estimated lives of the properties using the units-of-production method.  These capitalized costs are subject to a quarterly ceiling test that limits such pooled costs, net of applicable deferred taxes, to the aggregate of the present value of future net revenues attributable to proved natural gas, oil and NGL reserves discounted at 10% (standardized measure) plus the lower of cost or market value of unproved properties.  Any costs in excess of the ceiling are written off as a non-cash expense.  The expense may not be reversed in future periods, even though higher natural gas, oil and NGL prices may subsequently increase the ceiling.  Companies using the full cost method are required to use the average quoted price from the first day of each month from the previous 12 months, including the impact of derivatives designated for hedge accounting, to calculate the ceiling value of their reserves. Prices used to calculate the ceiling value of reserves were as follows:
December 31, 2021December 31, 2020
Natural gas (per MMBtu)
$3.60 $1.98 
Oil (per Bbl)
$66.56 $39.57 
NGLs (per Bbl)
$28.65 $10.27

Using the average quoted prices above, adjusted for market differentials, our net book value of our United States natural gas and oil properties did not exceed the ceiling amount at December 31, 2021. We had no derivative positions that were designated for hedge accounting as of December 31, 2021.  Future decreases in market prices, as well as changes in production rates, levels of reserves, evaluation costs excluded from amortization, future development costs and production costs may result in future non-cash impairments to our natural gas and oil properties.
The net book value of our natural gas and oil properties exceeded the ceiling amount in each quarter of 2020 resulting in a total non-cash full cost ceiling test impairment of $2,825 million.  We had no derivative positions that were designated for hedge accounting as of December 31, 2020.
No impairment expense was recorded in 2020 or 2021 in relation to our natural gas and oil properties acquired from Montage. These properties were recorded at fair value as of November 13, 2020, in accordance with ASC Topic 820 – Fair Value Measurement. In the fourth quarter of 2020, pursuant to SEC guidance, we determined that the fair value of the properties acquired at the closing of the Montage Merger clearly exceeded the related full-cost ceiling limitation beyond a reasonable doubt and received a waiver from the SEC to exclude the properties acquired in the Montage Merger from the ceiling test calculation. This waiver was granted for all reporting periods through and including the quarter ending September 30, 2021, as long as we could continue to demonstrate that the fair value of properties acquired clearly exceeded the full cost ceiling limitation beyond a reasonable doubt in each reporting period. As part of the waiver received from the SEC, we were required to disclose what the full cost ceiling test impairment amounts for all periods presented in each applicable quarterly and annual filing would have been if the waiver had not been granted. The fair value of the properties acquired in the Montage Merger was based on future commodity market pricing for natural gas and oil pricing existing at the date of the Montage Merger, and we affirmed that there has not been a material decline to the fair value of these acquired assets since the Montage Merger. The properties acquired in the Montage Merger had an unamortized cost at December 31, 2020 of $1,087 million. Had we not received the waiver from the SEC, the impairment charge recorded would have been an additional $539 million for the year ended December 31, 2020. Due to the improvement in commodity prices during 2021, no impairment charge would have been recorded in 2021 had the Montage natural gas and oil properties been included in the full cost ceiling test.
Changes in natural gas, oil and NGL prices used to calculate the discounted future net revenues of our reserves affects both the present value of cash flows and the quantity of reserves.  Our reserve base as of December 31, 2021 was approximately 82% natural gas, 2% NGLs and 16% oil, and our standardized measure and reserve quantities as of December 31, 2021, were $18.73 billion and 21.1 Tcfe, respectively.
Costs associated with unevaluated properties are excluded from our amortization base until we have evaluated the properties or impairment is indicated.  The costs associated with unevaluated leasehold acreage and related seismic data, wells currently drilling and related capitalized interest are initially excluded from our amortization base.  Leasehold costs are either transferred to our amortization base with the costs of drilling a well on the lease or are assessed at least annually for possible impairment or reduction in value.  Our decision to withhold costs from amortization and the timing of the transfer of those costs into the amortization base involves judgment and may be subject to changes over time based on several factors, including our drilling plans, availability of capital, project economics and drilling results from adjacent acreage.  At December 31, 2021, we had approximately $2,231 million of costs excluded from our amortization base, all of which related to our properties in the United States.  Inclusion of some or all of these costs in our properties in the United States in the future, without adding any associated reserves, could result in non-cash ceiling test impairments.
Proved natural gas, oil and NGL reserves are a major component of the full cost ceiling test. Natural gas, oil and NGL reserves cannot be measured exactly.  Our estimate of natural gas, oil and NGL reserves requires extensive judgments of reservoir engineering data and projections of costs that will be incurred in developing and producing reserves and is generally less precise than other estimates made in connection with financial disclosures.  Our reservoir engineers prepare our reserve estimates under the supervision of our management.  Reserve estimates are prepared for each of our properties annually by the reservoir engineers assigned to the asset management team for that property.  The reservoir engineering and financial data included in these estimates are reviewed by senior engineers, who are not part of the asset management teams, and by our Director of Reserves, who is the technical person primarily responsible for overseeing the preparation of our reserves estimates. Our Director of Reserves has more than 27 years of experience in petroleum engineering, including the estimation of natural gas and oil reserves, and holds a Bachelor of Science in Petroleum Engineering.  Prior to joining us in 2018, our Director of Reserves served in various reservoir engineering roles for EP Energy Company, El Paso Corporation, Cabot Oil & Gas Corporation, Schlumberger and H.J. Gruy & Associates, and is a member of the Society of Petroleum Engineers.  He reports to our Executive Vice President and Chief Operating Officer, who has more than 33 years of experience in petroleum engineering including the estimation of natural gas, oil and NGL reserves in multiple basins in the United States, and holds a Bachelor of Science in Petroleum Engineering.  Prior to joining Southwestern in 2017, our Chief Operating Officer served in various engineering and leadership roles for EP Energy

Corporation, El Paso Corporation, ARCO Oil and Gas Company, Burlington Resources and Peoples Energy Production, and is a member of the Society of Petroleum Engineers.
We engage NSAI, a worldwide leader of petroleum property analysis for industry and financial organizations and government agencies, to independently audit our proved reserves estimates as discussed in more detail below.  NSAI was founded in 1961 and performs consulting petroleum engineering services under Texas Board of Professional Engineers Registration No. F-002699. Within NSAI, the two technical persons primarily responsible for auditing our proved reserves estimates (1) have over 24 years and over 20 years of practical experience in petroleum geosciences and petroleum engineering, respectively; (2) have over 13 years and over 20 years of experience in the estimation and evaluation of reserves, respectively; (3) each has a college degree; (4) each is a Licensed Professional Geoscientist in the State of Texas or a Licensed Professional Engineer in the State of Texas; (5) each meets or exceeds the education, training, and experience requirements set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers; and (6) each is proficient in judiciously applying industry standard practices to engineering and geoscience evaluations as well as applying SEC and other industry reserves definitions and guidelines. The financial data included in the reserve estimates is also separately reviewed by our accounting staff. Our proved reserves estimates, as internally reviewed and audited by NSAI, are submitted for review and approval to our President and Chief Executive Officer.  Finally, upon his approval, NSAI reports the results of its reserve audit to the Board of Directors, with whom final authority over the estimates of our proved reserves rests.  A copy of NSAI’s report has been filed as Exhibit 99.1 to this Annual Report. 
Proved developed reserves generally have a higher degree of accuracy in this estimation process, when compared to proved undeveloped and proved non-producing reserves, as production history and pressure data over time is available for the majority of our proved developed properties.  Proved developed reserves accounted for 54% of our total reserve base as of December 31, 2021.  Assigning monetary values to such estimates does not reduce the subjectivity and changing nature of such reserve estimates.  The uncertainties inherent in the reserve estimates are compounded by applying additional estimates of the rates and timing of future production volumes and the costs that will be incurred in developing and producing the reserves.  We cannot assure you that our internal controls sufficiently address the numerous uncertainties and risks that are inherent in estimating quantities of natural gas, oil and NGL reserves and projecting future rates of production and timing of development expenditures as many factors are beyond our control.  We refer you to “Our proved natural gas, oil and NGL reserves are estimates that include uncertainties.  Any material changes to these uncertainties or underlying assumptions could cause the quantities and net present value of our reserves to be overstated or understated” in Item 1A, “Risk Factors,” of Part I of this Annual Report for a more detailed discussion of these uncertainties, risks and other factors.
In conducting its audit, the engineers and geologists of NSAI study our major properties in detail and independently develop reserve estimates.  NSAI's audit consists primarily of substantive testing, which includes a detailed review of all operated proved developed properties plus all proved undeveloped locations. The proved developed properties included in the NSAI audit account for approximately 99% of the proved developed reserve volume and 99% of the proved developed present worth as of December 31, 2021. The proved undeveloped properties included in the NSAI audit account for 100% of the proved undeveloped reserve volume and 100% of the proved undeveloped present worth as of December 31, 2021.  In the conduct of its audit, NSAI did not independently verify the data we provided to them with respect to ownership interests, natural gas, oil and NGL production, well test data, historical costs of operation and development, product prices, or any agreements relating to current and future operations of the properties and sales of production.  NSAI has advised us that if, in the course of its audit, something came to its attention that brought into question the validity or sufficiency of any such information or data, NSAI did not rely on such information or data until it had satisfactorily resolved any questions relating thereto or had independently verified such information or data.  On January 28, 2022, NSAI issued its audit opinion as to the reasonableness of our reserve estimates for the year-ended December 31, 2021 stating that our estimated proved natural gas, oil and NGL reserves are, in the aggregate, reasonable and have been prepared in accordance with Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers.
Business Combinations
We account for business combinations under the acquisition method of accounting. Accordingly, we recognize amounts for identifiable assets acquired and liabilities assumed equal to their estimated acquisition date fair values. We make various assumptions in estimating the fair values of assets acquired and liabilities assumed. As fair value is a market-based measurement, it is determined based on the assumptions that market participants would use. The most significant assumptions relate to the estimated fair values of proved and unproved oil and natural gas properties. Fair value of proved natural gas and oil properties as of the acquisition date was based on estimated proved natural gas, oil and NGL reserves and related discounted net cash flows. Significant inputs to the valuation include estimates of future production volumes, future operating and development costs, future commodity prices and a weighted average cost of capital rate. The market-based weighted average cost of capital rate is subjected to additional project-specific risking factors. In addition, when appropriate, we review comparable purchases and sales of natural
74

gas and oil properties within the same regions, and use that data as a proxy for fair market value as this is an indication of the amount that a willing buyer and seller would enter into in exchange for such properties. Any excess of the acquisition price over the estimated fair value of net assets acquired is recorded as goodwill. Any excess of the estimated fair value of net assets acquired over the acquisition price is recorded in current earnings as a gain on bargain purchase. Deferred taxes are recorded for any differences between the assigned values and the tax basis of assets and liabilities.

The Mergers qualified as business combinations, and as such, we estimated the fair values of the assets acquired and liabilities assumed as of respective acquisition dates. The fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Fair value measurements also utilize assumptions of market participants. We used discounted cash flow models and we made market assumptions as to future commodity prices, projections of estimated quantities of natural gas and oil reserves, expectations for timing and amount of future development and operating costs, projections of future rates of production, expected recovery rates and risk adjusted discount rates. These assumptions represent Level 3 inputs, as defined in Note 8 – Fair Value Measurements.
We recorded the net assets acquired and liabilities assumed in the Montage Merger at their estimated fair value on November 13, 2020 of approximately $213 million.
We recorded the net assets acquired and liabilities assumed in the Indigo Merger at their estimated fair value on September 1, 2021 of approximately $1,961 million.
We recorded the net assets acquired and liabilities assumed in the GEPH Merger at their estimated fair value on December 31, 2021 of approximately $1,732 million.
We consider the estimated fair values above to be representative of the prices paid by typical market participants. These measurements resulted in no goodwill or bargain purchases being recognized.
Derivatives and Risk Management
We use fixed price swap agreements and options to reduce the volatility of earnings and cash flow due to fluctuations in the prices of certain commodities and interest rates.  Our policies prohibit speculation with derivatives and limit agreements to counterparties with appropriate credit standings to minimize the risk of uncollectability.  We actively monitor the credit status of our counterparties based on their credit ratings and credit default swap rates where applicable, and to date have not had any credit defaults associated with our transactions.  In both 2021 and 2020, we financially protected 83% of our total production with derivatives.  The primary risks related to our derivative contracts are the volatility in market prices and basis differentials for our production.  However, the market price risk is generally offset by the gain or loss recognized upon the related transaction that is financially protected.
All derivatives are recognized in the balance sheet as either an asset or a liability as measured at fair value other than transactions for which the normal purchase/normal sale exception is applied.  Certain criteria must be satisfied for derivative financial instruments to be designated for hedge accounting. Accounting guidance for qualifying hedges allows an unsettled derivative’s unrealized gains and losses to be recorded in either earnings or as a component of other comprehensive income until settled.  In the period of settlement, we recognize the gains and losses from these qualifying hedges in gas sales revenues.  The ineffective portion of those fixed price swaps are recognized in earnings.  Gains and losses on derivatives that are not designated for hedge accounting treatment, or that do not meet hedge accounting requirements, are recorded as a component of gain (loss) on derivatives on the consolidated statements of operations. Accordingly, the gain (loss) on derivatives component of the statement of operations reflects the gains and losses on both settled and unsettled derivatives.  We calculate gains and losses on settled derivatives as the summation of gains and losses on positions which have settled within the reporting period.
As of December 31, 2021, none of our derivative contracts were designated for hedge accounting treatment.  Changes in the fair value of unsettled derivatives that were not designated for hedge accounting treatment are recorded in gain (loss) on derivatives.  See Note 6 to the consolidated financial statements included in this Annual Report for more information on our derivative position at December 31, 2021.
Future market price volatility could create significant changes to the derivative positions recorded in our consolidated financial statements.  We refer you to “Quantitative and Qualitative Disclosures about Market Risk” in Item 7A of Part II of this Annual Report for additional information regarding our hedging activities.
Pension and Other Postretirement Benefits
As part of ongoing effort to reduce costs, we have elected to freeze our pension plan effective January 1, 2021. Employees that were participants in the pension plan prior to January 1, 2021 will continue to receive the interest component of the plan but
75

Table of Contents
Index to Financial Statements
will no longer receive the service component. We have commenced the pension plan termination process, but the specific date for the completion of the process is unknown at this time and will depend on certain legal and regulatory requirements or approvals. As part of the termination process, we expect to distribute lump sum payments to or purchase annuities for the benefit of plan participants, which is dependent on the participants’ elections. In addition, we expect to make a payment equal to the difference between the total benefits due under the plan and the total value of the assets available, which, as of December 31, 2021, was approximately $12 million. Our current funding policy is to continue to contribute amounts which are actuarially determined to provide the plan with sufficient assets to meet future benefit payment requirements and which are tax deductible. We are in the process of evaluating the impact of the termination and future settlement accounting on our consolidated financial statements and related disclosures.
We record our prepaid or accrued benefit cost, as well as our periodic benefit cost, for our pension and other postretirement benefit plans using measurement assumptions that we consider reasonable at the time of calculation (see Note 13 to the consolidated financial statements included in this Annual Report for further discussion and disclosures regarding these benefit plans).  Two of the assumptions that affect the amounts recorded are the discount rate, which estimates the rate at which benefits could be effectively settled, and the expected return on plan assets, which reflects the average rate of earnings expected on the funds invested.  For the December 31, 2021 benefit obligation the initial discount rate assumed is 3.20%.  This compares to an initial discount rate of 3.10% for the benefit obligation and periodic benefit cost recorded in 2021.  For the 2022 periodic benefit cost, the expected return assumed was reduced from 5.10% to 0.10%, as the investment allocations have shifted from a balanced portfolio to short-term fixed-income assets in alignment with the plan termination process. Using the assumed rates discussed above, we recorded total benefit cost of $4 million in 2021 related to our pension and other postretirement benefit plans, which included a $2 million settlement adjustment.
As of December 31, 2021, we recognized a liability of $25 million, compared to $46 million at December 31, 2020, related to our pension and other postretirement benefit plans.  During 2021, we made cash contributions totaling $12 million to fund our pension and other postretirement benefit plans.
Long-term Incentive Compensation
Our long-term incentive compensation plans consist of a combination of stock-based awards that derive their value directly or indirectly from our common stock price, and cash-based awards that are fixed in amount, but subject to meeting annual performance thresholds. In March 2020, we issued our first long-term fixed cash-based awards.
We account for long-term incentive compensation transactions using a fair value method and recognize an amount equal to the fair value of the stock-based awards and cash-based awards cost in either the consolidated statement of operations or capitalize the cost into natural gas and oil properties included in property and equipment.  Costs are capitalized when they are directly related to the acquisition, exploration and development activities of our natural gas and oil properties.  We use models to determine fair value of stock-based compensation, which requires significant judgment with respect to forfeitures, volatility and other factors. The performance cash awards granted in 2021 and 2020 include a performance condition determined annually by the Company. If we, in our sole discretion, determine that the threshold was not met, the amount for that vesting period will not vest and will be cancelled.
Our stock-based compensation is classified as either an equity award or a liability award in accordance with generally accepted accounting principles.  The fair value of an equity-classified award is determined at the grant date and is amortized on a straight-line basis over the vesting life of the award.  The fair-value of a liability-classified award is determined on a quarterly basis through the final vesting date and is amortized based on the current fair value of the award and the percentage of vesting period incurred to date. See Note 14 to the consolidated financial statements included in this Annual Report for further discussion and disclosures regarding our long-term incentive compensation.
New Accounting Standards
Refer to Note 1 to the consolidated financial statements included in this Annual Report for further discussion of our significant accounting policies and for discussion of accounting standards that have been implemented in this report, along with a discussion of relevant accounting standards that are pending adoption.
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market risks relating to our operations result primarily from the volatility in commodity prices, basis differentials and interest rates, as well as service costs and credit risk concentrations.  We use fixed price swap agreements, options, swaptions, basis swaps and interest rate swaps to reduce the volatility of earnings and cash flow due to fluctuations in the prices of natural gas, oil and certain NGLs along with interest rates.  Our Board of Directors has approved risk management policies and procedures to utilize financial products for the reduction of defined commodity price risk.  Utilization of financial products for the reduction of interest

rate risks is also overseen by our Board of Directors.  These policies prohibit speculation with derivatives and limit swap agreements to counterparties with appropriate credit standings.
Credit Risk
Our exposure to concentrations of credit risk consists primarily of trade receivables and derivative contracts associated with commodities trading.  Concentrations of credit risk with respect to receivables are limited due to the large number of our purchasers and their dispersion across geographic areas.  For the year ended December 31, 2021, one purchaser accounted for 12% of our revenues. If we had completed the Indigo Merger and the GEPH Merger at the beginning of 2021, this same purchaser would have accounted for approximately 16% of our revenues. A default on this account could have a material impact on the Company.  For the year ended December 31, 2020, one purchaser accounted for 10% of our revenues.  See “Commodities Risk” below for discussion of credit risk associated with commodities trading.
Interest Rate Risk
As of December 31, 2021, we had approximately $4.4 billion of outstanding senior notes with a weighted average interest rate of 5.68%, $550 million of borrowings under our Term Loan facility and $460 million of borrowings under our 2018 credit facility.  We currently have an interest rate swap in effect to mitigate a portion of our exposure to volatility in interest rates.  At December 31, 2021, we had long-term debt issuer ratings of Ba2 by Moody’s, BB by S&P and BB by Fitch Ratings.  On September 1, 2021, S&P upgraded our bond rating to BB, and on January 6, 2022, S&P further upgraded our bond rating to BB+, which will have the effect of decreasing the interest rate on the 2025 notes to 5.95%, beginning with coupon payments paid after January 2022. Any further upgrades or downgrades in our public debt ratings by Moody’s or S&P could decrease or increase our cost of funds, respectively.

Commodities Risk
We use fixed price swap agreements and options to protect sales of our production against the inherent risks of adverse price fluctuations or locational pricing differences between a published index and the NYMEX futures market.  These swaps and options include transactions in which one party will pay a fixed price (or variable price) for a notional quantity in exchange for receiving a variable price (or fixed price) based on a published index (referred to as price swaps) and transactions in which parties agree to pay a price based on two different indices (referred to as basis swaps).
The primary market risks relating to our derivative contracts are the volatility in market prices and basis differentials for our production.  However, the market price risk is offset by the gain or loss recognized upon the related sale or purchase of the production that is financially protected. Credit risk relates to the risk of loss as a result of non-performance by our counterparties. The counterparties are primarily major banks and integrated energy companies that management believes present minimal credit risks. The credit quality of each counterparty and the level of financial exposure we have to each counterparty are closely monitored to limit our credit risk exposure. Additionally, we perform both quantitative and qualitative assessments of these counterparties based on their credit ratings and credit default swap rates where applicable. We have not incurred any counterparty losses related to non-performance and do not anticipate any losses given the information we have currently. However, we cannot be certain that we will not experience such losses in the future.  The fair value of our derivative assets and liabilities includes a non-performance risk factor. We refer you to Note 6 and Note 8 of the consolidated financial statements included in this Annual Report for additional details about our derivative instruments and their fair value.

Management’s Report on Internal Control Over Financial Reporting
It is the responsibility of the management of Southwestern Energy Company to establish and maintain adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934). Management has assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021, utilizing the Committee of Sponsoring Organizations of the Treadway Commission’s Internal Control – Integrated Framework (2013).
Based on this evaluation, management has concluded the Company’s internal control over financial reporting was effective as of December 31, 2021.
The effectiveness of our internal control over financial reporting as of December 31, 2021 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report which appears herein.
Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders of Southwestern Energy Company
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Southwestern Energy Company and its subsidiaries (the “Company”) as of December 31, 2021 and 2020, and the related consolidated statements of operations, of comprehensive income (loss), of changes in equity and of cash flows for each of the three years in the period ended December 31, 2021, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that
79

Table of Contents
Index to Financial Statements
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
The Impact of Proved Natural Gas, Oil and NGL Reserves on Natural Gas and Oil Properties
As described in Note 1 to the consolidated financial statements, the Company’s consolidated natural gas and oil properties balance was $33,631 million as of December 31, 2021, and depreciation, depletion and amortization expense for the year ended December 31, 2021 was $546 million. The Company utilizes the full cost method of accounting for its natural gas and oil properties. Under this method, all capitalized costs are amortized over the estimated lives of the properties using the unit-of-production method based on proved natural gas, oil and natural gas liquids (NGL) reserves. These capitalized costs are subject to a ceiling test that limits such pooled costs, net of applicable deferred taxes, to the aggregate of the present value of future net revenues attributable to proved natural gas, oil and NGL reserves discounted at 10%. As disclosed by management, proved natural gas, oil and NGL reserves are a major component of the full cost ceiling test. Estimates of reserves require extensive judgments of reservoir engineering data and projections of costs that will be incurred in developing and producing reserves. The uncertainties inherent in the reserve estimates are compounded by applying additional estimates of the rates and timing of future production volumes and the costs that will be incurred in developing and producing the reserves. The estimates of natural gas, oil and NGL reserves have been developed by specialists, specifically reservoir engineers, and audited by independent petroleum engineers (together referred to as “specialists”).
The principal considerations for our determination that performing procedures relating to the impact of proved natural gas, oil and NGL reserves on natural gas and oil properties is a critical audit matter are (i) the significant judgment by management, including the use of management’s specialists, when developing the estimates of proved natural gas, oil and NGL reserves, which in turn led to (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating audit evidence related to the data, methods, and assumptions used by management and its specialists in developing the estimates of proved natural gas, oil and NGL reserves and the assumption applied to the full cost ceiling test related to future production volumes.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s estimates of proved natural gas, oil and NGL reserves and the full cost ceiling test calculation. The work of management’s specialists was used in performing the procedures to evaluate the reasonableness of the estimates of proved natural gas, oil and NGL reserves and the reasonableness of future production volumes applied in the full cost ceiling test. As a basis for using this work, specialists’ qualifications were understood and the Company’s relationship with the specialists was assessed. The procedures performed also included evaluation of the methods and assumptions used by specialists, tests of the completeness and accuracy of the data used by the specialists, and an evaluation of specialists’ findings.
Acquisitions of Indigo Natural Resources LLC and GEP Haynesville, LLC – Valuation of Proved Natural Gas and Oil Properties
As described in Note 2 to the consolidated financial statements, the Company completed the acquisitions of Indigo Natural Resources LLC and GEP Haynesville, LLC for net consideration of $1,961 million and $1,732 million, respectively, which resulted in $4,507 million of proved natural gas and oil properties being recorded from these acquisitions. As disclosed by management, the Company accounts for business combinations under the acquisition method of accounting. Accordingly, the Company recognizes amounts for identifiable assets acquired and liabilities assumed equal to their estimated acquisition date fair

values. The most significant assumptions relate to the estimated fair values of proved natural gas and oil properties. Fair value of proved natural gas and oil properties as of the acquisition date was based on estimated proved natural gas, oil, and NGL reserves and related discounted net cash flows. Significant inputs to the valuation include estimates of future production volumes, future operating and development costs, future commodity prices and a weighted average cost of capital rate. The estimates of natural gas, oil and NGL reserves have been developed by specialists, specifically reservoir engineers, and audited by independent petroleum engineers (together referred to as “specialists”).
The principal considerations for our determination that performing procedures relating to the valuation of proved natural gas and oil properties from the acquisitions of Indigo Natural Resources LLC and GEP Haynesville, LLC is a critical audit matter are (i) the significant judgment by management, including the use of management’s specialists, when developing the fair value of acquired proved natural gas and oil properties, which in turn led to (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to future production volumes, future commodity prices, and the weighted average cost of capital rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the valuation of the acquired proved natural gas and oil properties. These procedures also included, among others (i) reading the purchase agreement; (ii) testing management’s process for developing the fair value of acquired proved natural gas and oil properties; (iii) evaluating the appropriateness of the discounted cash flow models; (iv) testing the completeness and accuracy of underlying data used in the discounted cash flow models; and (v) evaluating the reasonableness of significant assumptions used by management related to future production volumes, future commodity prices, and the weighted average cost of capital rate. Evaluating the reasonableness of management’s significant assumption related to future commodity prices involved comparing the future commodity prices against observable market data and evaluating commodity price differentials through inspection of the underlying contracts. Professionals with specialized skill and knowledge were used to assist in evaluating the appropriateness of the discounted cash flow models and the reasonableness of the weighted average cost of capital rate significant assumption. The work of management’s specialists was used in performing the procedures to evaluate the reasonableness of the proved natural gas and oil reserves as stated in the Critical Audit Matter titled “Impact of Proved Natural Gas, Oil and NGL Reserves on Natural Gas and Oil Properties” and the reasonableness of the future production volumes. As a basis for using this work, the specialists’ qualifications were understood and the Company’s relationship with the specialists was assessed. The procedures performed also included evaluation of the methods and assumptions used by the specialists, tests of the completeness and accuracy of the data used by the specialists, and an evaluation of the specialists’ findings.

SOUTHWESTERN ENERGY COMPANY AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Operations
Southwestern Energy Company (including its subsidiaries, collectively “Southwestern” or the “Company”) is an independent energy company engaged in natural gas, oil and NGLs exploration, development and production (“E&P”).  The Company is also focused on creating and capturing additional value through its marketing business (“Marketing”). Southwestern conducts most of its business through subsidiaries and operates principally in 2 segments: E&P and Marketing.  
E&P. Southwestern’s primary business is the exploration for and production of natural gas as well as associated NGLs and oil, with ongoing operations focused on the development of unconventional natural gas and oil reservoirs located in Pennsylvania, West Virginia, Ohio and Louisiana. The Company’s operations in Pennsylvania, West Virginia and Ohio, herein referred to as “Appalachia,” are primarily focused on the Marcellus Shale, the Utica and the Upper Devonian unconventional natural gas and liquids reservoirs. The Company’s operations in Louisiana, herein referred to as “Haynesville,” are primarily focused on the Haynesville and Bossier natural gas reservoirs. The Company also operates drilling rigs and provides certain oilfield products and services, principally serving the Company's E&P operations through vertical integration.
Marketing. Southwestern’s marketing activities capture opportunities that arise through the marketing and transportation of natural gas, oil and NGLs primarily produced in its E&P operations.
Basis of Presentation
The consolidated financial statements included in this Annual Report present the Company’s financial position, results of operations and cash flows for the periods presented in accordance with accounting principles generally accepted in the United States (“GAAP”).  The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities and disclosure of contingent assets and liabilities, if any, at the date of the financial statements, and the amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  The Company evaluates subsequent events through the date the financial statements are issued.
The comparability of certain 2021 amounts to prior periods could be impacted as a result of the Montage Merger (as defined below) in November 2020, the Indigo Merger (as defined below) on September 1, 2021, and the GEPH Merger (as defined below) on December 31, 2021. The Company believes the disclosures made are adequate to make the information presented not misleading.
Principles of Consolidation
The consolidated financial statements include the accounts of Southwestern and its wholly-owned subsidiaries.  All significant intercompany accounts and transactions have been eliminated.
In 2015, the Company purchased an 86% ownership in a limited partnership that owns and operates a gathering system in Appalachia.  Because the Company owns a controlling interest in the partnership, the operating and financial results are consolidated with the Company’s E&P segment results.  The minority partner’s share of the partnership activity is reported in retained earnings in the consolidated financial statements.  Net income attributable to noncontrolling interest for the years ended December 31, 2021, 2020 and 2019 was insignificant.
Major Customers
The Company sells the vast majority of its E&P natural gas, oil and NGL production to third-party customers through its marketing subsidiary.  Customers include major energy companies, utilities and industrial purchasers of natural gas. For the year ended December 31, 2021 1 purchaser accounted for 12% of annual revenues. A default on this account could have a material impact on the Company, but the Company does not believe that there is a material risk of a default.  For the year ended December 31, 2020, 1 purchaser accounted for 10% of annual revenues. No other purchasers accounted for more than 10% of consolidated revenues. The Company believes that the loss of any one customer would not have an adverse effect on its ability to sell its natural gas, oil and NGL production.
Cash and Cash Equivalents
Cash and cash equivalents are defined by the Company as short-term, highly liquid investments that have an original maturity of three months or less and deposits in money market mutual funds that are readily convertible into cash.  Management considers
87

Table of Contents
Index to Financial Statements
cash and cash equivalents to have minimal credit and market risk as the Company monitors the credit status of the financial institutions holding its cash and marketable securities.  The Company had $28 million and $13 million in cash and cash equivalents as of December 31, 2021 and 2020, respectively.
Certain of the Company’s cash accounts are zero-balance controlled disbursement accounts.  The Company presents the outstanding checks written against these zero-balance accounts as a component of accounts payable in the accompanying consolidated balance sheets.  Outstanding checks included as a component of accounts payable totaled $21 million and $16 million as of December 31, 2021 and 2020, respectively.
Property, Depreciation, Depletion and Amortization
Natural Gas and Oil Properties.  The Company utilizes the full cost method of accounting for costs related to the exploration, development and acquisition of natural gas and oil properties.  Under this method, all such costs (productive and nonproductive), including salaries, benefits and other internal costs directly attributable to these activities, are capitalized on a country-by-country basis and amortized over the estimated lives of the properties using the units-of-production method.  These capitalized costs are subject to a ceiling test that limits such pooled costs, net of applicable deferred taxes, to the aggregate of the present value of future net revenues attributable to proved natural gas, oil and NGL reserves discounted at 10% (standardized measure).  Any costs in excess of the ceiling are written off as a non-cash expense.  The expense may not be reversed in future periods, even though higher natural gas, oil and NGL prices may subsequently increase the ceiling.  Companies using the full cost method are required to use the average quoted price from the first day of each month from the previous 12 months, including the impact of derivatives designated for hedge accounting, to calculate the ceiling value of their reserves. Prices used to calculate the ceiling value of reserves were as follows:
For the years ended December 31,
202120202019
Natural gas (per MMBtu)
$3.60 $1.98 $2.58 
Oil (per Bbl)
$66.56 $39.57 $55.69 
NGLs (per Bbl)
$28.65 $10.27 $11.58 
Using the average quoted prices above, adjusted for market differentials, the net book value of the Company’s United States natural gas and oil properties did not exceed the ceiling amount at December 31, 2021 or 2019. The net book value of its natural gas and oil properties exceeded the ceiling amount in each quarter of 2020 resulting in a total non-cash full cost ceiling test impairment of $2,825 million. The Company had no derivative positions that were designated for hedge accounting as of December 31, 2021, 2020 and 2019.  Future decreases in market prices, as well as changes in production rates, levels of reserves, evaluation costs excluded from amortization, future development costs and production costs may result in future non-cash impairments to the Company’s natural gas and oil properties.
No impairment expense was recorded in 2020 or 2021 in relation to the Company’s natural gas and oil properties acquired from Montage. These properties were recorded at fair value as of November 13, 2020, in accordance with Accounting Standards Codification (“ASC”) Topic 820 – Fair Value Measurement. In the fourth quarter of 2020, pursuant to SEC guidance, the Company determined that the fair value of the properties acquired at the closing of the Montage Merger clearly exceeded the related full-cost ceiling limitation beyond a reasonable doubt and received a waiver from the SEC to exclude the properties acquired in the Montage Merger from the ceiling test calculation. This waiver was granted for all reporting periods through and including the quarter ending September 30, 2021, as long as the Company could continue to demonstrate that the fair value of properties acquired clearly exceeded the full cost ceiling limitation beyond a reasonable doubt in each reporting period. As part of the waiver received from the SEC, the Company was required to disclose what the full cost ceiling test impairment amounts for all periods presented in each applicable quarterly and annual filing would have been if the waiver had not been granted. The fair value of the properties acquired in the Montage Merger was based on future commodity market pricing for natural gas and oil pricing existing at the date of the Montage Merger, and management affirmed that there has not been a material decline to the fair value of these acquired assets since the Montage Merger. The properties acquired in the Montage Merger had an unamortized cost at December 31, 2020 of $1,087 million. Had management not received the waiver from the SEC, the impairment charge recorded would have been an additional $539 million for the year ended December 31, 2020. Due to the improvement in commodity prices during 2021, no impairment charge would have been recorded in 2021 had the Montage natural gas and oil properties been included in the full cost ceiling test.
Costs associated with unevaluated properties are excluded from the amortization base until the properties are evaluated or impairment is indicated.  The costs associated with unevaluated leasehold acreage and related seismic data, wells currently drilling and related capitalized interest are initially excluded from the amortization base.  Leasehold costs are either transferred to the amortization base with the costs of drilling a well on the lease or are assessed at least annually for possible impairment or reduction in value.  The Company’s decision to withhold costs from amortization and the timing of the transfer of those costs into
88

Index to Financial Statements
the amortization base involves judgment and may be subject to changes over time based on several factors, including drilling plans, availability of capital, project economics and drilling results from adjacent acreage.  At December 31, 2021, the Company had a total of $2,231 million of costs excluded from the amortization base, all of which related to its properties in the United States.
Capitalized Interest.  Interest is capitalized on the cost of unevaluated natural gas and oil properties that are excluded from amortization.
Asset Retirement Obligations.  Natural gas and oil properties require expenditures to plug and abandon the wells and reclaim the associated pads and other supporting infrastructure when the wells are no longer producing.  An asset retirement obligation associated with the retirement of a tangible long-lived asset such as oil and gas properties is recognized as a liability in the period incurred or when it becomes determinable, with an associated increase in the carrying amount of the related long-lived asset.  The cost of the tangible asset, including the asset retirement cost, is depreciated over the useful life of the asset.  The asset retirement obligation is recorded at its estimated fair value, and accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value.
Other Property and Equipment. The Company’s non-full cost pool assets include water facilities, gathering systems, technology infrastructure, land, buildings and other equipment with useful lives that range from 3 to 30 years.
The estimated useful lives of those assets depreciated under the straight-line method are as follows:
Water facilities5 – 10 years
Gathering systems15 – 25 years
Technology infrastructure3 – 7 years
Drilling rigs and equipment3 years
Buildings and leasehold improvements10 – 30 years

Impairment of Long-Lived Assets.  The carrying value of non-full cost pool long-lived assets is evaluated for recoverability whenever events or changes in circumstances indicate that it may not be recoverable.  Should an impairment exist, the impairment loss would be measured as the amount that the asset’s carrying value exceeds its fair value. For the years ended December 31, 2021 and 2020 the Company recognized non-cash impairments of $6 million and $5 million, respectively, for non-core assets.
Intangible Assets.  The carrying value of intangible assets are evaluated for recoverability whenever events or changes in circumstances indicate that it may not be recoverable. Intangible assets are amortized over their useful life. At December 31, 2021 and 2020, the Company had $48 million and $57 million, respectively, in marketing-related intangible assets, of which $43 million and $48 million were included in Other long-term assets on the respective consolidated balance sheets.  The Company amortized $8 million of its marketing-related intangible asset in December 31, 2021 and $9 million in each of the years ended December 31, 2020 and 2019, and expects to amortize $5 million in 2022 and for the four years thereafter.
Leases
The Company determines if a contract contains a lease at inception or as a result of an acquisition. A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment (an identified asset) for a period of time in exchange for consideration. A right-of-use asset and corresponding lease liability are recognized on the balance sheet at commencement at an amount based on the present value of the remaining lease payments over the lease term. As the implicit rate of the lease is not always readily determinable, the Company uses the incremental borrowing rate to calculate the present value of the lease payments based on information available at commencement date, such as the initial lease term. Operating right-of-use assets and operating lease liabilities are presented separately on the consolidated balance sheet. The

Company does not have any finance leases as of December 31, 2021. By policy election, leases with an initial term of twelve months or less are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis, and variable lease payments are recognized in the period as incurred.
Certain leases contain both lease and non-lease components. The Company has chosen to account for most of these leases as a single lease component instead of bifurcating lease and non-lease components. However, for compression service leases and fleet vehicle leases, the lease and non-lease components are accounted for separately.
The Company leases drilling rigs, pressure pumping equipment, vehicles, office space, certain water transportation lines and other equipment under non-cancelable operating leases expiring through 2039. Certain lease agreements include options to renew the lease, early terminate the lease or purchase the underlying asset(s). The Company determines the lease term at the lease commencement date as the non-cancelable period of the lease, including options to extend or terminate the lease when such an option is reasonably certain to be exercised. The Company’s water transportation lines are the only leases with renewal options that are reasonably certain to be exercised. These renewal options are reflected in the right-of-use asset and lease liability balances.
Income Taxes
The Company follows the asset and liability method of accounting for income taxes.  Under this method, deferred tax assets and liabilities are recorded for the estimated future tax consequences attributable to the differences between the financial carrying amounts of existing assets and liabilities and their respective tax basis.  Deferred tax assets and liabilities are measured using the tax rate expected to be in effect for the year in which those temporary differences are expected to reverse.  The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the year of the enacted rate change.  Deferred income taxes are provided to recognize the income tax effect of reporting certain transactions in different years for income tax and financial reporting purposes.  A valuation allowance is established to reducefor deferred tax assets, ifincluding net operating losses, is recognized when it is more likely than not that some or all of the relatedbenefit from the deferred tax benefitsassets will not be realized.
The Company accounts for uncertainty in income taxes using a recognition and measurement threshold for tax positions taken or expected to be taken in a tax return.  The tax benefit from an uncertain tax position is recognized when it is more likely than not that the position will be sustained upon examination by taxing authorities based on technical merits of the position.  The amount of the tax benefit recognized is the largest amount of the benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.  The effective tax rate and the tax basis of assets and liabilities reflect management’s estimates of the ultimate outcome of various tax uncertainties.  The Company recognizes penalties and interest related to uncertain tax positions within the provision (benefit) for income taxes line in the accompanying consolidated statements of operations.  Additional information regarding uncertain tax positions along with the impact of the Tax ReformCuts and Jobs Act can be found in Note 1111.

Derivative Financial Instruments
The Company uses derivative financial instruments to manage defined commodity price risks and does not use them for speculative trading purposes.  The Company uses derivative instruments to financially protect sales of natural gas, oil and NGLs.  In addition, the Company uses interest rate swaps to manage exposure to unfavorable interest rate changes.  Since the Company does not designate its derivatives for hedge accounting treatment, gains and losses resulting from the settlement of derivative contracts have been recognized in gain (loss) on derivatives in the consolidated statements of operations when the contracts expire and the related physical transactions of the underlying commodity are settled.  Additionally, changes in the fair value of the unsettled portion of derivative contracts are also recognized in gain (loss) on derivatives in the consolidated statement of operations.  See Note 6 and Note 8 for a discussion of the Company’s hedging activities.
Earnings Per Share
Basic earnings per common share is computed by dividing net income (loss) attributable to common stock by the weighted average number of common shares outstanding during the reportable period.  The diluted earnings per share calculation adds to the weighted average number of common shares outstanding: the incremental shares that would have been outstanding assuming the exercise of dilutive stock options, the vesting of unvested restricted shares of common stock, performancerestricted stock units and the assumed conversion of mandatory convertible preferred stock.performance units.  An antidilutive impact is an increase in earnings per share or a reduction in net loss per share resulting from the conversion, exercise, or contingent issuance of certain securities.
In January 2015,On December 31, 2021, the Company issued 34,500,000 depositary99,337,748 shares that entitled the holder to a proportional fractional interest in the rights and preferences of the mandatory convertible preferred stock, including conversion, dividend, liquidation and voting rights.  The mandatory convertible preferred stock had the non-forfeitable right to participate on an as-converted basis at the conversion rate then in effect in anyits common stock dividends declared and, therefore, was considered a participating security.  Accordingly, it has been included in conjunction with the computation of basic and diluted earnings per share, pursuant to the two-class method.  In the calculation of basic earnings per share attributable to common shareholders, earnings are allocated to participating securities based on actual dividend distributions received plus a proportionate share of undistributed net income attributable to common shareholders, if any, after recognizing distributed earnings.  The Company’s participating securities do not participate in undistributed net losses because they are not contractually obligated to do so.  In January 2018, all outstanding shares of mandatory convertible preferred stock were converted to 74,998,614GEPH Merger. These shares of the Company’s common stock.

Stock-Based Compensation
The Company accounts for stock-based compensation transactions using a fair value method and recognizes an amount equal to the fair value of the stock options and stock-based payment cost in either the consolidated statement of operations orand capitalizes the cost into natural gas and oil properties included in property and equipment.  Costs are capitalized when they are directly related to the acquisition, exploration and development activities of the Company’s natural gas and oil properties.  See Note 1414 for a discussion of the Company’s stock-based compensation.
Liability-Classified Awards
The Company classifies certain awards that can or will be settled in cash as liability awards. The fair value of a liability-classified award is determined on a quarterly basis beginning at the grant date until final vesting.  Changes in the fair value of liability-classified awards are recorded to general and administrative expense, oroperating expense and capitalized expense over the vesting period of the award.  The Company’s liability-classified performance unit awards that were granted in 2018 include a performance condition based on cash flow per debt-adjusted share and two market conditions, one based on absolute total shareholder return (“TSR”) and the other on relative total shareholder returnTSR as compared to a group of the Company’s peers.  The Company’s liability-classified performance unit awards that were granted in 2019 include a performance condition based on the return of average capital employed and the same two market conditions as in the 2018 awards. The liability-based performance unit awards granted in 2020 include a performance condition based on return on average capital employed and a market condition based on relative TSR. In 2021, two types of performance unit awards were granted. One type of award includes a performance condition based on return on capital employed and a performance condition based on a reinvestment rate, and the second type of award includes one market condition based on relative TSR. The fair values of the two market conditions discussed above are calculated by Monte Carlo models on a quarterly basis. See Note 14 for a discussion of the Company’s stock-based compensation.
Cash-Based Compensation
The Company classifies certain awards that will be settled in cash as cash-based compensation. The Company recognizes the cost of these awards as general and administrative expense, operating expense and capitalized expense over the vesting period of the awards. The performance cash awards include a performance condition determined annually by the Company. If the Company, in its sole discretion, determines that the threshold was not met, the amount for that vesting period will not vest and will be canceled.

(2) ACQUISITIONS AND DIVESTITURES
GEP Haynesville, LLC Merger
On November 3, 2021, Southwestern entered into an Agreement and Plan of Merger with Mustang Acquisition Company, LLC (“Mustang”), GEP Haynesville, LLC (“GEPH”) and GEPH Unitholder Rep, LLC (the “GEPH Merger Agreement”). Pursuant to the terms of the GEPH Merger Agreement, GEPH merged with and into Mustang, a subsidiary of Southwestern, and became a wholly-owned subsidiary of Southwestern (the “GEPH Merger”).

The GEPH Merger constituted a business combination, and was accounted for using the acquisition method of accounting. For tax purposes, the GEPH Merger was treated as a sale of partnership interests and an acquisition of assets. The following table presents the fair value of consideration transferred to GEPH equity holders as a result of the GEPH Merger:

The following table sets forth the preliminary fair value of the assets acquired and liabilities assumed as of the acquisition date. Certain data and studies necessary to complete the purchase price allocation are still under evaluation, including, but not limited to, the final actualization of accrued liabilities and receivable balances and the valuation of natural gas and oil properties. The Company will finalize the purchase price allocation during the twelve-month period following the acquisition date, during which time the value of the assets and liabilities may be revised as appropriate.

The assets acquired and liabilities assumed were recorded at their preliminary estimated fair values at the date of the GEPH Merger. Acquired working capital amounts are expected to approximate fair value due to their short-term nature. The valuation of certain assets, including property, are based on preliminary appraisals. The fair value of acquired equipment is based on both available market data and a cost approach.
With the completion of the GEPH Merger, Southwestern acquired proved and unproved properties of approximately $1,783 million and $59 million, respectively, primarily associated with the Haynesville and Bossier formations. The remaining $2 million in Other property, plant and equipment consists of land, facilities and various equipment.
The income approach was utilized for unevaluated and evaluated oil and gas properties based on underlying reserve projections at the GEPH Merger date. Income approaches are considered Level 3 fair value estimates and include significant assumptions of future production, commodity prices, and operating and capital cost estimates, discounted using weighted average cost of capital for industry peers, and risk adjustment factors based on reserve category. Price assumptions were based on observable market pricing adjusted for historical differentials. Cost estimates were based on current observable costs inflated based on historical and expected future inflation. Taxes were based on current statutory rates.

The Company considered the borrowings under the revolving credit facility to approximate fair value as the balance on the GEPH revolving credit facility was immediately paid off after the GEPH Merger close. The value of derivative instruments was based on observable inputs, primarily forward commodity-price curves, and is considered Level 2.
Since the date of the GEPH Merger occurred on December 31, 2021, there were no revenues or operating income associated with the operations acquired recorded in the Company’s consolidated statements of operations for the year ended December 31, 2021.
Indigo Natural Resources Merger

The following table sets forth the preliminary fair value of the assets acquired and liabilities assumed as of the acquisition date. Certain data and studies necessary to complete the purchase price allocation are still under evaluation, including, but not limited to, the valuation of natural gas and oil properties and the resolution of certain matters that the Company is indemnified for under the Indigo Merger Agreement for which not enough information is available to assess the final fair value of at this time. The Company will finalize the purchase price allocation during the twelve-month period following the acquisition date, during which time the value of the assets and liabilities may be revised as appropriate.

The assets acquired and liabilities assumed were recorded at their preliminary estimated fair values at the date of the Indigo Merger. Acquired working capital amounts are expected to approximate fair value due to their short-term nature. The valuation of certain assets, including property, are based on preliminary appraisals. The fair value of acquired equipment is based on both available market data and a cost approach.
With the completion of the Indigo Merger, Southwestern acquired proved and unproved properties of approximately $2,724 million and $684 million, respectively, primarily associated with the Haynesville and Bossier formations. The remaining $4 million in Other property, plant and equipment consists of land, water facilities and various equipment.
The income approach was utilized for unevaluated and evaluated oil and gas properties based on underlying reserve projections at the Indigo Merger date. Income approaches are considered Level 3 fair value estimates and include significant assumptions of future production, commodity prices, and operating and capital cost estimates, discounted using weighted average cost of capital for industry peers, and risk adjustment factors based on reserve category. Price assumptions were based on observable market pricing adjusted for historical differentials. Cost estimates were based on current observable costs inflated based on historical and expected future inflation. Taxes were based on current statutory rates.
The measurement of senior unsecured notes was based on unadjusted quoted prices in an active market and are Level 1. The Company considered the borrowings under the 2018 credit facility to approximate fair value as the outstanding Indigo revolving credit facility was immediately paid off after the Indigo Merger close. The value of derivative instruments was based on observable inputs, primarily forward commodity-price and interest-rate curves and is considered Level 2.
From the date of the Indigo Merger through December 31, 2021, revenues and operating income associated with the operations acquired through the Indigo Merger totaled $682 million and $472 million, respectively.
Prior to the Indigo Merger, in May 2021, Indigo closed on an agreement to divest its Cotton Valley natural gas and oil properties. Indigo retained certain contractual commitments related control environment upon adoptionto volume commitments associated with natural gas

gathering, for which Southwestern will assume the obligation to pay the gathering provider for any unused portion of the volume commitment under the agreement through 2027, depending on the buyer’s actual use. As of December 31, 2021, up to approximately $36 million of these contractual commitments remain, and the Company has recorded a $17 million liability for the estimated future payments.
Excluding the Cotton Valley gathering agreement (discussed above), the Company has recorded additional liabilities totaling $74 million as of December 31, 2021, primarily related to purchase or volume commitments associated with gathering, fresh water and sand. These amounts will be recognized as payments are made over a period ranging from two to seven years.
Montage Resources Merger
In August 2020, Southwestern entered into an Agreement and Plan of Merger with Montage Resources Corporation (“Montage”) whereby Montage would merge with and into Southwestern, with Southwestern continuing as the surviving company (the “Montage Merger”). On November 12, 2020, Montage’s stockholders voted to approve the Montage Merger and it was made effective on November 13, 2020. The Montage Merger added to Southwestern’s oil and gas portfolio in Appalachia.
In exchange for each share of Montage common stock, Montage stockholders received 1.8656 shares of Southwestern common stock, plus cash in lieu of any fractional share of Southwestern common stock that otherwise would have been issued, based on the average price of $3.05 per share of Southwestern common stock on the NYSE on November 13, 2020.
In anticipation of the Montage Merger, in August 2020 Southwestern issued $350 million of new senior unsecured notes and 63,250,000 shares of common stock for $152 million after deducting underwriting discounts and offering expenses. The Company used the net proceeds from the debt and common stock offerings and borrowings under its 2018 credit facility to fund a redemption of $510 million aggregate principal amount of Montage's outstanding 8.875% senior notes due 2023 (the "Montage Notes") and related accrued interest in connection with the closing of the Montage Merger. See Note 1 and Note 9 for additional information.
The Montage Merger constitutes a business combination and was accounted for using the acquisition method of accounting. The following table presents the fair value of consideration transferred to Montage stockholders as a result of the Montage Merger:

(1)Reflects a $10 million purchase price adjustment due to completion of valuation assessments during the measurement period.

The assets acquired and liabilities assumed were recorded at their fair values at the date of the Montage Merger. The valuation of certain assets, including property, are based on appraisals. The fair value of acquired equipment is based on both available market data and a cost approach.
With the completion of the Montage Merger, Southwestern acquired proved and unproved properties of approximately $1,012 million and $100 million, respectively, primarily associated with the Appalachian basin. The remaining $28 million in Other property, plant and equipment consists of a gathering system, buildings and various equipment.
Unevaluated oil and gas properties were valued primarily using a market approach based on comparable transactions for similar properties. The income approach was utilized for proved oil and gas properties based on underlying reserve projections at the Montage Merger date. Income approaches are considered Level 3 fair value estimates and include significant assumptions of future production, commodity prices, and operating and capital cost estimates, discounted using weighted average cost of capital for industry peers, and risk adjustment factors based on reserve category. Price assumptions were based on observable market pricing adjusted for historical differentials. Cost estimates were based on current observable costs inflated based on historical and expected future inflation. Taxes were based on current statutory rates.
Deferred income taxes represent the tax effects of differences in the tax basis and merger-date fair values of assets acquired and liabilities assumed. A full valuation was placed on all deferred tax assets assumed from Montage consistent with the Company’s treatment of its deferred tax asset balance as of December 31, 2020. The measurement of senior unsecured notes was based on unadjusted quoted prices in an active market and are primarily Level 1. The Company considered the borrowings under the 2018 credit facility to approximate fair value as the outstanding Montage revolving credit facility was immediately paid off after the Montage Merger closed. The value of derivative instruments was based on observable inputs, primarily forward commodity-price and interest-rate curves and is considered Level 2.
From the date of the Montage Merger through December 31, 2020, revenues and the net income attributable to common stockholders associated with the operations acquired through the Montage Merger totaled $63 million and $28 million, respectively.

The unaudited pro forma information is not necessarily indicative of the operating results that would have occurred had the Montage Merger been completed at January 1, 2019, and the Indigo Merger and the GEPH Merger each been completed at January 1, 2020, nor is it necessarily indicative of future operating results of the combined entities. The unaudited pro forma information gives effect to the Mergers and any related equity and debt issuances, along with the use of proceeds therefrom, as if they had occurred on the respective dates discussed above and is a result of combining the statements of operations of Southwestern with the pre-merger results of Montage, Indigo and GEPH, including adjustments for revenues and direct expenses. The pro forma results exclude any cost savings anticipated as a result of the Mergers, and include adjustments to DD&A (depreciation, depletion and amortization) based on the purchase price allocated to property, plant, and equipment and the estimated useful lives as well as adjustments to interest expense. Interest expense was adjusted to reflect any retirement of assumed senior notes, credit facilities, all related accrued interest and the associated decrease in amortization of issuance costs related to notes retired and revolving lines of credit. These decreases were partially offset by increases in interest on debt associated with the issuance of $350 million in 8.375% Senior Notes due 2028 related to the Southwestern debt offering and borrowings under Southwestern’s credit facility used to pay off the Montage notes, Montage credit facility and related accrued interest. Interest expense was also adjusted to include the impact of the assumption and exchange of Indigo’s $700 million of 5.375% Senior Notes due 2029 for equivalent Southwestern senior notes and to reflect the retirement of the Montage, Indigo and GEPH credit facilities, all related accrued interest and the associated decreases in amortization of issuance costs related to the respective revolving lines of credit. Management believes the estimates and assumptions are reasonable, and the relative effects of the three Mergers are properly reflected.

In August 2018, the Company entered into an agreement with Flywheel Energy Operating, LLC to sell 100% of the equity in the Company’s subsidiaries that owned and operated its Fayetteville Shale E&P and related midstream gathering assets for $1,865 million in cash, subject to customary closing adjustments, with an economic effective date of July 1, 2018.
In December 2018, the Company closed the Fayetteville Shale sale and received approximately $1,650 million, which included purchase price adjustments of approximately $215 million primarily related to the net cash flows from the economic

effective date to the closing date.  The Company allocated the sale proceeds to gain on sale for the non-full cost pool assets and to capitalized costs for the full cost pool assets based on the proportion of the estimated fair values of the underlying assets. The fair values of these assets was estimated primarily using an income approach. Consequently, the Company recognized a gain on the sale of non-full cost pool assets of $17 million and a reduction of $887 million to its full cost pool assets. As the sale did not involve a significant change in proved reserves or significantly alter the relationship between capitalized costs and proved reserves, the Company recognized no gain or loss related to the full cost pool assets sold.

As part of the Fayetteville Shale sale agreement, the Company entered into certain natural gas derivative positions that were subsequently novated to the buyer in conjunction with finalization of the sale. The unrealized fair value of these derivatives at the closing of the sale in December 2018 was a net liability of $151 million, which was transferred to the buyer. The unrealized loss associated with the novated positions was offset by the gain that the Company recognized when the liability was transferred to the buyer. These offsetting amounts were recognized on the consolidated statements of operations in (gain) loss on sale of operating assets, net. In addition, the Company paid $22 million in premiums for these novated derivatives which was recorded as a loss in (gain) loss on sale of operating assets, net in 2018.
The Company retained certain contractual commitments related to firm transportation, with the buyer obligated to pay the transportation provider directly for these charges.  As of December 31, 2019, approximately $108 million of these contractual commitments remain, of which the Company will reimburse the buyer for certain of these potential obligations up to approximately $58 million through 2020 depending on the buyer’s actual use. At December 31, 2019, the Company has recorded a $46 million liability for the estimated future payments. 
In accordance with accounting guidance for Property, Plant and Equipment, assets held for sale are measured at the lower of the carrying value or fair value less costs to sell. Because the assets outside the full cost pool included in the Fayetteville Shale sale met the criteria for held for sale accounting as of September 30, 2018, the Company determined the carrying value of certain non-full cost pool assets exceeded the fair value less costs to sell. As a result, a non-cash impairment charge of $161 million was recorded in the third quarter of 2018, of which $145 million related to midstream gathering assets held for sale and $15 million related to E&P assets held for sale. Additionally, the Company recorded a $1 million non-cash impairment related to other non-core assets that were not included in the sale.
From the proceeds received, $914 million was used to repurchase $900 million of the Company’s outstanding senior notes, including premiums and $9 million in accrued interest paid in December 2018. In addition, $201 million, including approximately $1 million in commissions, was used to repurchase approximately 44 million shares of the Company's outstanding common stock, including $21 million in the first quarter of 2019. The Company earmarked the remaining net proceeds from the sale to supplement 2019 and 2020 Appalachia development and for general corporate purposes. Pending these other uses, a portion of these remaining net proceeds has been used to repay revolving credit facility borrowings until investments are made.
During 2019, the Company sold non-core acreage for $38 million. There was no production or proved reserves associated with this acreage. In addition, during July 2019, the Company sold the land associated with its headquarters office building for $16 million and recognized a $2 million gain on the sale. The Company also from time to time sells leases and other properties whose value, individually, is not material but is reflected in the Company’s financial statements.

(4) LEASES
In February 2016,As part of the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (“Update 2016-02”), which seeks to increase transparency and comparability among organizations by, among other things, recognizing leaseIndigo Merger, the Company acquired $4 million of operating right of use assets and corresponding lease liabilities which were recognized as part of the Company’s acquisition accounting in the third quarter of 2021. The Company also acquired $2 million of operating right of use assets and corresponding lease liabilities related to the GEPH Merger of which $1 million had already commenced and was reflected on the balance sheet for leases classified as operating leases under previous GAAP and disclosing key information about leasing arrangements. The codification was amended through additional ASUs. For public entities, Update 2016-02 became effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company adopted ASC 842 with an effective date of January 1, 2019 using the modified retrospective approach for all leases that existed at the date of initial adoption. The Company elected to apply the transition as of the beginning of the period of adoption. For leases that existed at the period of adoption on January 1, 2019, the incremental borrowing rate as of the adoption date was used to calculate the present value of remaining lease payments.
The standard provides optional practical expedients to ease the burden of transition. The Company has adopted the following practical expedients through implementation:
an election not to apply the recognition requirements in the leases standard to short-term leases and recognize lease payments in the consolidated statement of operations (a lease that at commencement date has an initial term of 12 months or less and does not contain a purchase option that the Company is reasonably certain to exercise);
86

Table of Contents
Index to Financial Statements
a package of practical expedients to not reassess: whether a contract is or contains a lease, lease classification and initial direct costs;
a practical expedient that permits combining lease and non-lease components in a contract and accounting for the combination as a lease (elected by asset class);
a practical expedient to not reassess certain land easements in existence prior to January 1, 2019; and
an election to adopt the modified retrospective approach for all leases existing at or entered into after the initial date of adoption which does not require a restatement of prior period. No cumulative-effect adjustment to retained earnings was required as a result of the modified retrospective approach.
Upon adoption of ASC 842, the Company recognized a discounted right-of-use asset and corresponding lease liability with opening balances of approximately $105 million as of January 1, 2019. The adoption of the standard did not materially change the Company’s consolidated statement of operations or its consolidated statement of cash flows.
The Company determines if a contract contains a lease at inception. A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment (an identified asset) for a period of time in exchange for consideration. A right-of-use asset and corresponding lease liability are recognized on the balance sheet at commencement at an amount based on the present value of the remaining lease payments over the lease term. As the implicit rate of the lease is not always readily determinable, the Company uses the incremental borrowing rate to calculate the present value of the lease payments based on information available at commencement date, such as the initial lease term. Operating right-of-use assets and operating lease liabilities are presented separately on the consolidated balance sheet. The Company does not have any finance leases as of December 31, 2019. By policy election, leases with an initial term2021. The GEPH Merger closed during the fourth quarter of twelve months or less are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis, and variable lease payments are recognized in the period as incurred.2021.
Certain leases contain both lease and non-lease components. The Company has chosen to account for most of these leases as a single lease component instead of bifurcating lease and non-lease components. However, for compression service leases and fleet vehicle leases, the lease and non-lease components are accounted for separately.
The Company leases drilling rigs, pressure pumping equipment, vehicles, office space, certain water transportation lines, an aircraft and other equipment under non-cancelable operating leases expiring through 2032. Certain lease agreements include options to renew the lease, early terminate the lease or purchase the underlying asset(s). The Company determines the lease term at the lease commencement date as the non-cancelable period of the lease, including options to extend or terminate the lease when such an option is reasonably certain to be exercised. The Company’s water transportation lines are the only leases with renewal options that are reasonably certain to be exercised. These renewal options are reflected in the right-of-use asset and lease liability balances.
In July 2019, the Company terminated its existing lease agreement and entered into a new ten-year lease agreement for a smaller portion of the headquarters office building, which resulted in the Company making a $6 million residual value guarantee short-fall payment to the building’s previous lessor. The Company’s variable lease costs are primarily comprised of variable operating charges incurred in connection with the new buildingits headquarters lease. The variable lease whichcosts are expected to continue throughout the lease term. There are currently no material residual value guarantees in the Company’s existing leases.

Company performed an analysis of the impact of adopting ASC 606 across all revenue streams and did not identify any changes to its revenue recognition policies that resulted in a material impact to its consolidated financial statements.
Revenues from Contracts with Customers
Natural gas and liquids.  Natural gas, oil and NGL sales are recognized when control of the product is transferred to the customer at a designated delivery point.  The pricing provisions of the Company’s contracts are primarily tied to a market index with certain adjustments based on factors such as delivery, quality of the product and prevailing supply and demand conditions in

Index to Financial Statements
the geographic areas in which the Company operates.  Under the Company’s sales contracts, the delivery of each unit of natural gas, oil and NGLs represents a separate performance obligation, and revenue is recognized at the point in time when the performance obligations are fulfilled.  There is no significant financing component to the Company’s revenues as payment terms are typically within 30 to 60 days of control transfer.  Furthermore, consideration from a customer corresponds directly with the value to the customer of the Company’s performance completed to date.  As a result, the Company recognizes revenue in the amount to which the Company has a right to invoice and has not disclosed information regarding its remaining performance obligations.
The Company records revenue from its natural gas and liquids production in the amount of its net revenue interest in sales from its properties.  Accordingly, natural gas and liquid sales are not recognized for deliveries in excess of the Company’s net revenue interest, while natural gas and liquid sales are recognized for any under-delivered volumes.  Production imbalances are generally recorded as receivables and payables and not contract assets or contract liabilities as the imbalances are between the Company and other working interest owners, not the end customer.
Marketing.  The Company, through its marketing affiliate, generally markets natural gas, oil and NGLs for its affiliated E&P companies as well as other joint owners who choose to market with the Company.  In addition, the Company markets some products purchased from third parties.  Marketing revenues for natural gas, oil and NGL sales are recognized when control of the product is transferred to the customer at a designated delivery point.  The pricing provisions of the Company’s contracts are primarily tied to a market indexindices with certain adjustments based on factors such as delivery, quality of the product and prevailing supply and demand conditions.  Under the Company’s marketing contracts, the delivery of each unit of natural gas, oil and NGLs represents a separate performance obligation, and revenue is recognized at the point in time when the performance obligations are fulfilled.  Customers are invoiced and revenues are recorded each month as natural gas, oil and NGLs are delivered, and payment terms are typically within 30 to 60 days of control transfer.  Furthermore, consideration from a customer corresponds directly with the value to the customer of the Company’s performance completed to date.  As a result, the Company recognizes revenue in the amount to which the Company has a right to invoice and has not disclosed information regarding its remaining performance obligations.
Gas gathering.  Prior to the Fayetteville Shale sale in December 2018, the Company, through its midstream gathering affiliate, gathered natural gas pursuant to a variety of contracts with customers, including an affiliated E&P company.  The performance obligations for gas gathering services included delivery of each unit of natural gas to the designated delivery point, which may include treating of certain natural gas units to meet interstate pipeline specifications.  Revenue was recognized at the point in time when performance obligations were fulfilled.  Under the Company’s gathering contracts, customers were invoiced and revenue was recognized each month based on the volume of natural gas transported and treated at a contractually agreed upon price per unit.  Payment terms were typically within 30 to 60 days of completion of the performance obligations.  Furthermore, consideration from a customer corresponded directly with the value to the customer of the Company’s performance completed to date.  As a result, the Company recognized revenue in the amount to which the Company had a right to invoice and had not disclosed information regarding its remaining performance obligations.  Any imbalances were settled on a monthly basis by cashing-out with the respective shipper.  Accordingly, there were 0 contract assets or contract liabilities related to the Company’s gas gathering revenues.

(6) DERIVATIVES AND RISK MANAGEMENT
The Company is exposed to volatility in market prices and basis differentials for natural gas, oil and NGLs, which impacts the predictability of its cash flows related to the sale of those commodities. These risks are managed by the Company’s use of certain derivative financial instruments.  As of December 31, 2019,2021, the Company’s derivative financial instruments consisted of fixed price swaps, two-way costless collars, three-way costless collars, basis swaps, call options and interest rate swaps.  A description of the Company’s derivative financial instruments is provided below:
Fixed price swapsIf the Company sells a fixed price swap, the Company receives a fixed price for the contract, and pays a floating market price to the counterparty.  If the Company purchases a fixed price swap, the Company receives a floating market price for the contract, and pays a fixed price to the counterparty.
Two-way costless collarsArrangements that contain a fixed floor price (purchased(“purchased put option)option”) and a fixed ceiling price (sold(“sold call option)option”) based on an index price which, in aggregate, have no net cost.  At the contract settlement date, (1) if the index price is higher than the ceiling price, the Company pays the counterparty the difference between the index price and ceiling price, (2) if the index price is between the floor and ceiling prices, no payments are due from either party, and (3) if the index price is below the floor price, the Company will receive the difference between the floor price and the index price.
Three-way costless collarsArrangements that contain a purchased put option, a sold call option and a sold put option based on an index price which,that, in aggregate, have no net cost.  At the contract settlement date, (1) if the index price is higher than the sold call strike price, the Company pays the counterparty the difference between the index price and sold call strike price, (2) if the index price is between the purchased put strike price and the sold call strike price, no payments are due from either party, (3) if the index price is between the sold put strike price and the purchased put strike price, the Company will receive the difference between the purchased put strike price and the index price, and (4) if the index price is below the sold put strike price, the Company will receive the difference between the purchased put strike price and the sold put strike price.

Basis swapsArrangements that guarantee a price differential for natural gas from a specified delivery point.  If the Company sells a basis swap, the Company receives a payment from the counterparty if the price differential is greater than the stated terms of the contract, and pays the counterparty if the price differential is less than the stated terms of the contract.  If the Company purchases a basis swap, the Company pays the counterparty if the price differential is greater than the statestated terms of the contract, and receives a payment from the counterparty if the price differential is less than the stated terms of the contract.
Call optionsOptions (Calls and Puts)The Company purchases and sells call options in exchange for a premium.premiums.  If the Company purchases a call option, the Company receives from the counterparty the excess (if any) of the market price over the strike price of the call option at the time of settlement, but if the market price is below the call’s strike price, no payment is due from either party.  If the Company sells a call option, the Company pays the counterparty the excess (if any) of the market price over the strike price of the call option at the time of settlement, but if the market price is below the call’s strike price, no payment is due from either party. If the Company purchases a put option, the Company receives from the counterparty the excess (if any) of the strike price over the market price of the put option at the time of settlement, but if the market price is above the put’s strike price, no payment is due from either party. If the Company sells a put option, the Company pays the counterparty the excess (if any) of the strike price over the market price of the put option at the time of settlement, but if the market price is above the put’s strike price, no payment is due from either party.
SwaptionsInstruments that refer to an option to enter into a fixed price swap. In exchange for an option premium, the purchaser gains the right but not the obligation to enter a specified swap agreement with the issuer for specified future dates. If the Company sells a swaption, the counterparty has the right to enter into a fixed price swap wherein the Company receives a fixed price for the contract and pays a floating market price to the counterparty. If the Company purchases a swaption, the Company has the right to enter into a fixed price swap wherein the Company receives a floating market price for the contract and pays a fixed price to the counterparty.
Interest rate swapsInterest rate swaps are used to fix or float interest rates on existing or anticipated indebtedness.  The purpose of these instruments is to manage the Company’s existing or anticipated exposure to unfavorable interest rate changes.
The Company chooses counterparties for its derivative instruments that it believes are creditworthy at the time the transactions are entered into, and the Company actively monitors the credit ratings and credit default swap rates of these counterparties where applicable. However, there can be no assurance that a counterparty will be able to meet its obligations to the Company.  The Company presents its derivative positions on a gross basis and does not net the asset and liability positions.
As part of the Fayetteville Shale sale agreement, the Company entered into certain natural gas derivative positions that were subsequently novated to the buyer in conjunction with finalization of the sale. The derivatives that were novated to the buyer are not included in the tables below.

(3)Includes $9 million in premiums paid related to certain natural gas fixed price swaps recognized as a component of derivative assets within current assets on the consolidated balance sheet. 
The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value.  As presented in the tables below, this hierarchy consists of three broad levels:
Level 1 valuations –Consist of unadjusted quoted prices in active markets for identical assets and liabilities and have the highest priority.
Level 2 valuations –Consist of quoted market information for the calculation of fair market value.
Level 3 valuations –Consist of internal estimates and have the lowest priority.

The carrying values of cash and cash equivalents, including marketable securities, accounts receivable, other current assets, accounts payable and other current liabilities on the consolidated balance sheets approximate fair value because of their short-term nature.  For debt and derivative instruments, the following methods and assumptions were used to estimate fair value:

Table of Contents
Index to Financial Statements
Debt: The fair values of the Company’s senior notes were based on the market value of the Company’s publicly traded debt as determined based on the market prices of the Company’s senior notes.  These instruments were previously classified as a Level 2 measurement but certain senior notes were updatedDue to a Level 1 inlimited trading activity, the second quarter of 2018 as the market activity for a portionfair value of the Company’s debt resulted in timely quoted prices.  In 2019, theCompany's 4.10% Senior Notes due March 2022 were reclassified asis considered to be a Level 2 measurement dueon the fair value hierarchy. The fair values of the Company's more actively traded remaining senior notes are considered to relative market inactivity. The 4.05% Senior Notes due January 2020, which were classified asbe a Level 2 measurement at December 31, 2018, were retired in December 2019.
1 measurement. The carrying valuevalues of the borrowings under both the Company’s revolvingCompany's 2018 credit facility (to the extent utilized) and Term Loan approximates fair value because the interest rate isrates are variable and reflective of market rates. The Company considers the fair valuevalues of its revolving2018 credit facility and Term Loan to be a Level 1 measurement on the fair value hierarchy.
Derivative Instruments: The Company measures the fair value of allits derivative instruments isbased upon a pricing model that utilizes market-based inputs, including, but not limited to, the amount at whichcontractual price of the instrument could be exchanged currently between willing parties.  The amountsunderlying position, current market prices, natural gas and liquids forward curves, discount rates such as the LIBOR curve for a similar duration of each outstanding position, volatility factors and non-performance risk. Non-performance risk considers the effect of the Company’s credit standing on the fair value of derivative liabilities and the effect of counterparty credit standing on the fair value of derivative assets. Both inputs to the model are based on quoted market prices, best estimates obtained from counterpartiespublished credit default swap rates and an option pricing model, when necessary, for price option contracts.the duration of each outstanding derivative position. As of December 31, 2021, the impact of non-performance risk on the fair value of the Company’s net derivative liability position was a reduction of the liability of $3 million.
The Company has classified its derivativesderivative instruments into the fair value hierarchy levels depending upon the data utilized to determine their fair values.  The Company’s fixed price swaps (Level 2) are estimated using third-party discounted cash flow calculations using the New York Mercantile Exchange (“NYMEX”) futures index for natural gas and oil derivatives and Oil Price Information Service (“OPIS”) for ethane and propane derivatives.  The Company utilizes discounted cash flow models for valuing its interest rate derivatives (Level 2).  The net derivative values attributable to the Company’s interest rate derivative contracts as of December 31, 20192021 are based on (i) the contracted notional amounts, (ii) active market-quoted London Interbank Offered Rate (“LIBOR”) yield curves and (iii) the applicable credit-adjusted risk-free rate yield curve. The Company’s interest rate derivative contracts expire in June 2020.
The Company’s call and put options, two-way costless collars, and three-way costless collars (Level 2) are valued using the Black-Scholes model, an industry standard option valuation model that takes into account inputs such as contract terms, including maturity, and market parameters, including assumptions of the NYMEX and OPIS futures index, interest rates, volatility and credit worthiness.  The Company’s basis swaps (Level 2) are estimated using third-party calculations based upon forward commodity price curves.  These instruments were previously classified as a Level 3 measurement in the fair value hierarchy but were updated to a Level 2 measurement in the second quarter of 2018 as a result of the Company’s ability to derive volatility inputs and forward commodity price curves from directly observable sources.
Inputs to the Black-Scholes model, including the volatility input are obtained from a third-party pricing source, with independent verification of the most significant inputs on a monthly basis.  An increase (decrease) in volatility would result in an increase (decrease) in fair value measurement, respectively. Swaptions are valued using a variant of the Black-Scholes model referred to as the Black Swaption model, which uses its own separate volatility inputs.
The Company’s basis swaps (Level 2) are estimated using third-party calculations based upon forward commodity price curves.

Concurrent with the closing of the 2018 credit facility agreement in April 2018, the Company repaid the $1,191 million secured term loan balance and recognized a loss on early debt extinguishment of $8 million on the consolidated income statement related to the unamortized issuance expense.  In addition, approximately $4 million of unamortized issuance expense associated with the closed $743 million revolving credit facility was carried forward into the unamortized issuance expenses of the 2018 credit facility.  
2018 Credit Facility
In April 2018, the Company replaced its credit facility entered into in 2016 with a new revolving credit facility (the “2018 credit facility”). with a group of banks that, as amended, has a maturity date of April 2024.  The 2018 credit facility has an aggregate maximum revolving credit amount of $3.5 billion, with a current aggregate commitment of $2.0 billion and in October 2021, the banks participating in the 2018 credit facility reaffirmed the elected borrowing base (limit on availability) thatand aggregate commitments to be $2.0 billion. The borrowing base is redeterminedsubject to redetermination at least eachtwice a year, which typically occurs in April and October.  The 2018 credit facilityOctober, and is secured by substantially all of the assets owned by the Company and its subsidiaries. The permitted lien provisions in the senior notes indentures currently limit liens securing indebtedness to the greater of $2.0 billion and 25% of adjusted consolidated net tangible assets. On October 8, 2019, the

letters of credit. Loans under the 2018 credit facility are subject to varying rates of interest based on whether the loan is a Eurodollar loan or an alternate base rate loan.  Eurodollar loans bear interest at the Eurodollar rate, which is adjusted LIBOR for such interest period plus the applicable margin (as those terms are defined in the 2018 credit facility documentation).  The applicable margin for Eurodollar loans under the 2018 credit facility, as amended, ranges from 1.50%1.75% to 2.50%2.75% based on the Company’s utilization of the borrowing base under the 2018 credit facility.  Alternate base rate loans bear interest at the alternate base rate plus the applicable margin.  The applicable margin for alternate base rate loans under the 2018 credit facility, as amended, ranges from 0.50%0.75% to 1.50%1.75% based on the Company’s utilization of the borrowing base under the 2018 credit facility.
The 2018 credit facility contains customary representations and warranties and covenants including, among others, the following: 
a prohibition against incurring debt, subject to permitted exceptions;
a restriction on creating liens on assets, subject to permitted exceptions;  
restrictions on mergers and asset dispositions; 
restrictions on use of proceeds, investments, transactions with affiliates, or change of principal business; and
maintenance of the following financial covenants, commencing with the fiscal quarter ended June 30, 2018:
(1)Minimum current ratio of no less than 1.00 to 1.00, whereby current ratio is defined as the Company’s consolidated current assets (including unused commitments under the credit agreement, but excluding non-cash derivative assets) to consolidated current liabilities (excluding non-cash derivative obligations and current maturities of long-term debt).
(2)Maximum total net leverage ratio of no greater than, (i) with respect to each fiscal quarter ending during the period from June 30, 2018 through March 31, 2019, 4.50 to 1.00, (ii) with respect to each fiscal quarter ending during the period from June 30, 2019 through March 31, 2020, 4.25 to 1.00, and (iii) with respect to each fiscal quarter ending on or after June 30, 2020, 4.00 to 1.00.  Total net leverage ratio is defined as total debt less cash on hand (up to the lesser of 10% of credit limit or $150 million) divided by consolidated EBITDAX for the last four consecutive quarters.  For purposes of calculating consolidated EBITDAX, the Company can include the Indigo and GEPH consolidated EBITDAX prior to the respective Mergers for the same twelve-month rolling period. EBITDAX, as defined in the Company’s 2018 credit agreement, excludes the effects of interest expense, depreciation, depletion and amortization, income tax, any non-cash impacts from impairments, certain non-cash hedging activities, stock-based compensation expense, non-cash gains or losses on asset sales, unamortized issuance cost, unamortized debt discount and certain restructuring costs.

The 2018 credit facility contains customary events of default that include, among other things, the failure to comply with the financial covenants described above, non-payment of principal, interest or fees, violation of covenants, inaccuracy of representations and warranties, bankruptcy and insolvency events, material judgments and cross-defaults to material indebtedness.  If an event of default occurs and is continuing, all amounts outstanding under the 2018 credit facility may become immediately due and payable.  As of December 31, 2019,2021, the Company was in compliance with all of the covenants of the credit agreement in all material respects.
Each United States domestic subsidiary of the Company for which the Company owns 100% of its equity guarantees the 2018 credit facility.  Pursuant to requirements under the indentures governing its senior notes, each subsidiary that became a guarantor of the 2018 credit facility also became a guarantor of each of the Company’s senior notes.  See Note 16 for the Company’s Condensed Consolidated Financial Information, presented in accordance with Rule 3-10 of Regulation S-X.
As of December 31, 2019,2021, the Company had $172$160 million in letters of credit and $34$460 million in borrowings outstanding under the 2018 credit facility. The Company currently does not anticipate being required to supply a materially greater amount of letters of credit under its existing contracts.
The Company's exposure to the anticipated transition from LIBOR is limited to the 2018 credit facility. The USD-LIBOR settings are expected to be published through June 2023, and Southwestern anticipates using a variation of this rate until the underlying agreements are extended beyond the LIBOR publication date.
Term Loan Credit Agreement
On December 22, 2021, the Company entered into a term loan credit agreement with a group of lenders that provided for a $550 million secured term loan facility which matures in June 2027 (the “Term Loan”). As of December 31, 2021, the Company had borrowings under this Term Loan of $550 million. The net proceeds from the initial loans of $542 million were used to fund a portion of the GEPH Merger on December 31, 2021. Beginning on March 31, 2022, the Term Loan will require minimum quarterly payments of $1.375 million, subject to adjustment for voluntary prepayments. The Term Loan is subject to varying rates of interest based on whether the term loan is a term benchmark loan or an alternate base rate loan. Term benchmark loans bear interest at the adjusted term secured overnight financing rate (which includes a credit spread adjustment and is subject to a floor that is 0.50%) plus an applicable margin equal to 2.50%. Alternate base rate loans bear interest at the alternate base rate plus an applicable margin equal to 1.50%. The current borrowings are considered benchmark loans and are carried an interest rate of 3.00% as of December 31, 2021 (0.50% floor plus 2.50% margin).
The term loan is subject to a quarterly collateral coverage ratio test in which the Company’s PDP PV-10 value, net of derivative mark-to-market value, must be greater than 2.0x its secured debt commitments or all secured debt becomes callable. If necessary, outstanding secured debt principal can be paid down within 45 days of the end of such fiscal quarter to come into compliance with this ratio, either by (i) prepaying the loans, (ii) prepaying the loans under the 2018 credit facility, (iii) prepaying any other secured indebtedness that is secured by a lien, or some combination thereof.

The Company’s obligations under the Term Loan are guaranteed by each of the Company’s subsidiaries that guarantee the obligations under the 2018 credit facility and are secured by liens on substantially all the assets of the Company and the Company’s subsidiaries on an equal basis with the liens securing the obligations under the 2018 credit facility.

In February and June 2016, Moody’s andEffective in July 2018, the interest rate for the 2015 Notes was 6.20%, reflecting a net downgrade in the Company's bond ratings since their issuance. On April 7, 2020, S&P downgraded the Notes,Company's bond rating to BB-, which had the effect of increasing the interest rates by 175 basis points effective July 2016.  As a result of these downgrades, interest rates increased to 5.80% for the 2020 Notes and 6.70% forrate on the 2025 Notes.  InNotes to 6.45% following the event of future downgrades, the coupons for this series of notes were capped at 6.05% and 6.95%, respectively.July 23, 2020 interest payment due date. The first coupon payment to the bondholders at the higher interest ratesrate was paid in January 2017.2021. On September 1, 2021, S&P and Moody’s subsequently upgraded the Notes in AprilCompany’s bond rating to BB, and May 2018, respectively.  As a resulton January 6, 2022, S&P further upgraded the Company’s bond rating to BB+, which will have the effect of these upgrades,decreasing the interest rates decreased to 5.30% for the 2020 Notes and 6.20% forrate on the 2025 Notes effective July 2018.  The firstto 5.95% beginning with coupon payment to bondholders at the lower interest rates waspayments paid inafter January 2019.

Environmental Risk
The Company is subject to laws and regulations relating to the protection of the environment.  Environmental and cleanup related costs of a non-capital nature are accrued when it is both probable that a liability has been incurred and when the amount can be reasonably estimated.  Management believes any future remediation or other compliance related costs will not have a material effect on the financial position, results of operations or cash flows of the Company.
Litigation
The Company is subject to various litigation, claims and proceedings, most of which have arisen in the ordinary course of business such as for alleged breaches of contract, miscalculation of royalties, employment matters, traffic accidents, pollution, contamination, encroachment on others’ property or nuisance.  The Company accrues for litigation, claims and proceedings when a liability is both probable and the amount can be reasonably estimated.  As of December 31, 2019,2021, the Company does not currently have any material amounts accrued related to litigation matters.matters, including the cases discussed below. For any matters not accrued for, it is not possible at this time to estimate the amount of any additional loss, or range of loss, that is reasonably possible, but, based on the nature of the claims, management believes that current litigation, claims and proceedings, individually or in aggregate and after taking into account insurance, are not likely to have a material adverse impact on the Company’s financial position, results of operations or cash flows, for the period in which the effect of that outcome becomes reasonably estimable.  Many of these matters are in early stages, so the allegations and the damage theories have not been fully developed, and are all subject to inherent uncertainties; therefore, management’s view may change in the future.
Arkansas Royalty Litigation
The Company was a defendant in 3 certified class actions alleging that the Company underpaid lessors of lands in Arkansas by deducting from royalty payments costs for gathering, transportation and compression of natural gas in excess of what is permitted by the relevant leases. NaN of these class actions were filed in Arkansas state courts and the third in the United States District court for the Eastern District of Arkansas. The Company denied liability in all 3 cases.
In 2017, the jury returned a verdict in favor of the Company on all counts in Smith v. SEECO, Inc. et al., the class action in the federal court, whose plaintiff class comprised the vast majority of the lessors in these cases. The plaintiff had asserted claims for, among other things, breach of contract, fraud, civil conspiracy, unjust enrichment and violation of certain Arkansas statutes.

Following the verdict, the court entered judgment in favor of the Company on all claims. The trial court denied the plaintiff’s motion for a new trial, and the plaintiff appealed to the United States Court of Appeals for the Eighth Circuit. Independent of the plaintiff’s appeal, several different parties sought to intervene in the Smith case prior to or shortly after trial, and have appealed the trial court’s order denying their request to intervene. Oral argument occurred in January 2019. On April 23, 2019, the Court of Appeals affirmed the trial court’s order denying all requests to intervene in the case, and, in a separate order, affirmed the trial court’s judgment in favor of the Company on all claims. The Court of Appeals subsequently denied all requests for rehearing.
In 2018, the company entered into an agreement to settle another of the class actions, which was pending in the Circuit Court of Conway County, Arkansas under the caption Snow, et al v. SEECO, Inc., et al. The settlement received final approval by the court and the deadline to appeal the order approving the settlement passed without any appeals filed. The amount of the settlement was reflected in the Company’s consolidated statement of operations for 2018 and has been paid. The third class action was also dismissed in 2018.
As of December 31, 2019, some actions filed on behalf of mineral interest owners who opted out of the class actions mentioned above remain pending. The Company does not expect those cases to have a material adverse effect on the results of operations, financial position or cash flows of the Company. Additionally, it is not possible at this time to estimate the amount of any additional loss, or range of loss, that is reasonably possible.
St. Lucie County Fire District Firefighters’ Pension Trust
On October 17, 2016, the St. Lucie County Fire District Firefighters’ Pension Trust filed a putative class action in the 61st District Court in Harris County, Texas, against the Company, certain of its former officers and current and former directors and the underwriters on behalf of itself and others that purchased certain depositary shares from the Company’s January 2015 equity offering, alleging material misstatements and omissions in the registration statement for that offering. The Company removed the case to federal court, but after a decision by the United States Supreme Court in an unrelated case that these types of cases are not subject to removal, the federal court remanded the case to the Texas state court. The Texas trial court denied the Company’s motion to dismiss, and in February 2020, the court of appeals declined to exercise discretion to reverse the trial court’s decision. The Company filed a petition to review the trial court’s decision with the Texas Supreme Court, and the Court requested a response from the plaintiff. The Court subsequently requested full briefing on the merits of the case. The Company carries insurance for the claims asserted against it and the officer and director defendants, and the carrier has accepted coverage. On June 15, 2021, the parties agreed to a settlement of the case without any admission of liability. The Company’s insurance carrier is fully funding the settlement amount. On October 21, 2021, the court orally approved the settlement agreement. It signed a final judgment dismissing the litigation on October 22, 2021.

Bryant Litigation
As further discussed in Note 2, on September 1, 2021, the Company denies allcompleted the Indigo Merger, resulting in the assumption of Indigo’s existing litigation.
On June 12, 2018, a collection of 51 individuals and entities filed a lawsuit against 15 oil and gas company defendants, including Indigo, in Louisiana state court claiming damages arising out of current and historical exploration and production activity on certain acreage located in DeSoto Parish, Louisiana. The plaintiffs, who claim to own the properties at issue, assert that Indigo’s actions and the actions of other current operators conducting exploration and production activity, combined with the improper plugging and abandoning of legacy wells by former operators, have caused environmental contamination to their properties. Among other things, the plaintiffs contend that the defendants’ conduct resulted in the migration of natural gas, along with oilfield contaminants, into the Carrizo-Wilcox aquifer system underlying certain portions of DeSoto Parish. The plaintiffs assert claims based in tort, breach of contract and for violations of the Louisiana Civil and Mineral Codes, and they seek injunctive relief and monetary damages in an unspecified amount, including punitive damages.
On September 13, 2018, Indigo filed a variety of exceptions in response to the plaintiffs’ petition in this matter. Since the initial filing, supplemental petitions have been filed joining additional individuals and entities as plaintiffs in the matter. On September 29, 2020, plaintiffs filed their fourth supplemental and amending petition in response to the court’s order ruling that plaintiffs’ claims were improperly vague and failed to identify with reasonable specificity the defendants’ allegedly wrongful conduct. Indigo and the majority of the other defendants filed several exceptions to plaintiffs’ fourth amended petition challenging the sufficiency of plaintiffs’ allegations and intendseeking dismissal of certain claims. On February 18, 2021, plaintiffs filed a fifth supplemental and amending petition, which seeks to continueaugment the claims of select plaintiffs. On October 11, 2021, a sixth supplemental petition was filed which seeks to defend this case vigorously. add the Company as a party to the litigation.
The presence of natural gas in a localized area of the Carrizo-Wilcox aquifer system in DeSoto Parish is currently the subject of a regulatory investigation by the Louisiana Office of Conservation (“Conservation”), and the Company is cooperating and coordinating with Conservation in that investigation. The Conservation matter number is EMER18-003.

Additionally, it is not possible at this time to estimate the amount of any additional loss, or range of loss, that is reasonably possible.liquidity.
Indemnifications
The Company has provided certain indemnifications to various third parties, including in relation to asset and entity dispositions, securities offerings and other financings, such as the St. Lucie County Fire District Firefighters’ Pension Trust case described above.financings. In the case of asset dispositions, these indemnifications typically relate to disputes, litigation or tax matters existing at the date of disposition.  The Company likewise obtains indemnification for future matters when it sells assets, although there is no assurance the buyer will be capable of performing those obligations. In the case of equity offerings, these indemnifications typically relate to claims asserted against underwriters in connection with an offering. NaNNo material liabilities have been recognized in connection with these indemnifications.

The Tax Reform Act made significant changes to the U.S. federal income tax law affecting the Company.  Major changes in this legislation applicable to the Company relate to the reduction in the corporate tax rate to 21%, repeal of the alternative minimum tax, interest deductibility and net operating loss carryforward limitations, changes to certain executive compensation and full expensing provisions related to business assets.  The adjustments required to deferred taxes as a result of the Tax Reform Act have been reflected in the Company’s tax provision. 
As the Tax ReformCuts and Jobs Act repealed the corporate alternative minimum tax for tax years beginning on or after January 1, 2018 and provided for existing alternative minimum tax credit carryovers to be refunded beginning in 2018, the Company has approximately $30 million in refundable credits remaining that are expected to be fully refunded by 2021.credits.  Accordingly, in 2017 the valuation allowance in place prior to the Tax ReformCuts and Jobs Act related to these credits was released, and any credits remaining were reclassed to a receivable.
Additionally, in January 2020 the IRS announced that any previously sequestered amounts relating to these alternative minimum tax refunds would also be refunded. The Company had approximately $2 million in sequestered amounts relating to alternative minimum tax refunds. All of those refunds have been received as of December 2020 after the CARES Act (enacted in March 2020) accelerated alternative minimum tax refunds. In 2019,2020, the Company received refunds related to statefederal income tax of $1.0$32 million.  In 2018, theThe Company paid $6.3received a refund of $1 million in state income tax.tax in 2019.
Due to the issuance of common stock associated with the Indigo Merger, as discussed in Note 2 to the consolidated financial statements to this Annual Report, the Company incurred a cumulative ownership change and as such, the Company’s net operating losses (“NOLs”) prior to the acquisition are subject to an annual limitation under Internal Revenue Code Section 382 of approximately $48 million. The ownership changes and resulting annual limitation will result in the expiration of NOLs or other tax attributes otherwise available, with a corresponding decrease in the Company’s valuation allowance. At December 31, 2021, the Company had approximately $4 billion of federal NOL carryovers, of which approximately $3 billion have an expiration date between 2035 and 2037 and $1 billion have an indefinite carryforward life. The Company currently estimates that approximately $2 billion of these federal NOLs will expire before they are able to be used. The non-expiring NOLs remain subject to a full valuation allowance. If a subsequent ownership change were to occur as a result of future transactions in the Company’s common stock, the Company’s use of remaining U.S. tax attributes may be further limited. Included in the Company’s net operating loss carryforward asare the net operating loss carryforwards acquired in the Montage acquisition of December 31, 2019 was $3.0 billion$858 million.

2021.
A valuation allowance for deferred tax assets, including net operating losses, is recognized when it is more likely than not that some or all of the benefit from the deferred tax assets will not be realized.  To assess that likelihood, the Company uses estimates and judgment regarding future taxable income, and considers the tax consequences in the jurisdiction where such taxable income is generated, to determine whether a valuation allowance is required.  Such evidence can include current financial position, results of operations, both actual and forecasted, the reversal of deferred tax liabilities, and tax planning strategies as well as current and forecasted business economics of the oil and gas industry.
For the years ended December 31, 2018 and 2017, the Company maintained a full valuation allowance against its deferred tax assets based on its conclusion, considering all available evidence (both positive and negative), that it was more likely than not that the deferred tax assets would not be realized. A significant item of objective negative evidence considered was the cumulative pre-tax loss incurred over the three-year period ended December 31, 2018, primarily due to non-cash impairments of proved natural gas and oil properties recognized in 2015 and 2016. As of the first quarter of 2019, the Company had sustained a three-year cumulative level of profitability. Based on this factor and other positive evidence including forecasted taxable income, the Company concluded that it was more likely than not that the deferred tax assets would be realized and determined that $522 million of the valuation allowance would be released during 2019. Accordingly, a tax benefit of $522 million was recorded.
In 2020, due to significant pricing declines and the material write-down of the carrying value of the Company’s natural gas and oil properties in addition to other negative evidence, the Company concluded that it was more likely than not that its deferred tax assets would not be realized and recorded a valuation allowance. As of December 31, 2019,2021, the Company expects to retainstill maintains a full valuation allowance. The Company also retained a valuation allowance of $87$59 million related to net operating losses in jurisdictions in which it no longer operates. Management will continue to assess available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit the use of deferred tax assets. The Company is continually evaluatingamount of the deferred tax asset realizability, andconsidered realizable, however, could be adjusted based on changes in subjective estimates of future taxable income or if pricing changes occur that would significantly affect the forecast, the Company will reconsider the need for a valuation allowance at such time.objective negative evidence is no longer present.

The Company has a 401(k) defined contribution plan covering eligible employees. The Company expensed $2 million $3 million and $3 million of contribution expense in 2019, 2018each of 2021, 2020 and 2017,2019, respectively.

Defined Benefit Pension and Other Postretirement Plans
Prior to January 1, 1998,2021, substantially all of the Company maintained a traditionalCompany’s employees were covered by the defined benefit plan with benefits payable based upon average final compensation and years of service.  Effective January 1, 1998, the Company amended its pension, plan to become a “cash balance” plan on a prospective basis for its non-bargaining employees. A cash balance plan providesthat provided benefits based upon a fixed percentage of an employee’s annual compensation. As part of an ongoing effort to reduce costs, the Company elected to freeze its pension plan effective January 1, 2021. Employees that were participants in the pension plan prior to January 1, 2021 continued to receive the interest component of the plan but no longer received the service component. On September 13, 2021, the Compensation Committee of the Board of Directors approved terminating the Company’s pension plan, effective December 31, 2021, subject to approval by the Internal Revenue Service. This decision, among other benefits, will provide plan participants quicker access to, and greater flexibility in, the management of participants’ respective benefits due under the plan.
The Company’s funding policyCompany has commenced the pension plan termination process, but the specific date for the completion of the process is unknown at this time and will depend on certain legal and regulatory requirements or approvals. As part of the termination process, the Company expects to contribute amountsdistribute lump sum payments to or purchase annuities for the benefit of plan participants, which are actuarially determinedis dependent on the participants’ elections. In addition, the Company expects to providemake a payment equal to the plans with sufficientdifference between the total benefits due under the plan and the total value of the assets to meet future benefit payment requirements andavailable, which, are tax deductible.as of December 31, 2021, was $11 million.
The postretirement benefit plan provides contributory health care and life insurance benefits. Employees become eligible for these benefits if they meet age and service requirements. Generally, the benefits paid are a stated percentage of medical expenses reduced by deductibles and other coverages.
Substantially all of the Company’s employees arecontinue to be covered by the defined benefit pension and postretirement benefit plans.  The Company accounts for its defined benefit pension and other postretirement plans by recognizing the funded status of each defined pension benefit plan and other postretirement benefit plan on the Company’s balance sheet. In the event a plan is overfunded, the Company recognizes an asset. Conversely, if a plan is underfunded, the Company recognizes a liability.

The Southwestern Energy Company 2013 Incentive Plan was adopted in February 2013, approved by stockholders in May 2013 and amended and restated per stockholders’ approval in May 2016 and further amended in May 2017 and May 2019 (the “2013 Plan”).  The 2013 Plan provides for the compensation of officers, key employees and eligible non-employee directors of the Company and its subsidiaries.
The 2013 Plan provides for grants of options, stock appreciation rights, and shares of restricted stock and restricted stock units to employees, officers and directors that, in the aggregate, do not exceed 88,700,000 shares.  The types of incentives that may be awarded are comprehensive and are intended to enable the Company’s Board of Directors to structure the most appropriate incentives and to address changes in income tax laws which may be enacted over the term of the 2013 Plan.
The Company’s current long-term incentive compensation plans consist of a combination of stock-based awards that derive their value directly or indirectly from the Company’s common stock price, and cash-based awards that are fixed in amount but are subject to meeting annual performance thresholds.
The Company recorded the following costs related to long-term incentive compensation for the years ended December 31, 2021, 2020 and 2019:

Stock-Based Compensation
The Company’s stock-based compensation is classified as either equity or liability awards in accordance with GAAP.  The fair value of an equity-classified award is determined at the grant date and is amortized to general and administrative expense and capitalized expense on a straight-line basis over the vesting period of the award.  The fair value of a liability-classified award is determined on a quarterly basis beginning at the grant date until final vesting.  Changes in the fair value of liability-classified awards are recorded to general and administrative expense over the vesting period of the award.  A portion of this general and administrative expense is capitalized into natural gas and oil properties, included in property and equipment.  Generally, stock options granted to employees and directors vest ratably over three years from the grant date and expire seven years from the date of grant.  The Company issues shares of restricted stock or restricted stock units to employees and directors which generally vest over four years.  Restricted stock, restricted stock units and stock options granted to participants under the 2013 Plan, as amended and restated, immediately vest upon death, disability or retirement (subject to a minimum of three years of service). The Company issues performance units which have historically vested over three years to employees. The performance units granted in 20182019, 2020 and 20192021 cliff-vest at the end of three years.
In June 2018, the Company announced a workforce reduction.  Unvested stock-based awards of the affected employees were subsequently cancelled and the approximate fair value of a portion of those cancelled awards was includedAs further discussed in a cash severance payment that was paidNote 3, in the third quarter of 2018.  Stock-based compensation costs recognized prior to the cancellation as either general and administrative expense or capitalized expense were reversed and the severance payments were subsequently recognized as restructuring charges for the year ended December 31, 2018 on the consolidated statements of operations.
In December 2018, the Company closed the Fayetteville Shale sale.  As part of this transaction, most employees associated with those assets became employees of the buyer although the employment of some was terminated.  AllIn February of 2021 and 2020, the Company notified employees of workforce reduction plans as a result of strategic realignments of the Company’s organizational structure. Employees affected employeesby these events were offered a severance package, which included a one-time cash payment depending on length of service and, if applicable, the current value of a portion of equityunvested long-term incentive awards that were forfeited. Stock-based compensation costs recognized prior to the cancellation as either general and administrative expense or capitalized expense were reversed and the severance payments were subsequently recognized as restructuring charges for the years ended December 31, 20192021, 2020 and 20182019 on the consolidated statements of operations.

The fair value of stock options is estimated on the date of the grant using a Black-Scholes valuation model that uses the weighted average assumptions noted in the following table.  Expected volatility is based on historical volatility of the Company’s common stock and other factors.  The Company uses historical data on the exercise of stock options, post-vesting forfeitures and other factors to estimate the expected term of the stock-based payments granted.  The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant.

(16)CONDENSED CONSOLIDATING FINANCIAL INFORMATION
In April 2018, the Company entered into the 2018 credit facility.  Pursuant to requirements under the indentures governing the Company’s senior notes, each 100% owned subsidiary that became a guarantor of the 2018 credit facility also became a guarantor of each of the Company’s senior notes (the “Guarantor Subsidiaries”).  The Guarantor Subsidiaries also granted liens and security interests to support their guarantees under the 2018 credit facility but not of the senior notes.  These guarantees are full and unconditional and joint and several among the Guarantor Subsidiaries.  Certain of the Company’s operating units which are accounted for on a consolidated basis do not guarantee the 2018 credit facility and senior notes (“Non-Guarantor Subsidiaries”).  See Note 9 for additional information on the Company’s 2018 revolving credit facility and senior notes.  At the closing of the Fayetteville Shale sale in December 2018, its subsidiaries being sold were released from these guarantees.  See Note 3 for additional information on the divestiture of the Company’s Fayetteville Shale-related subsidiaries.
The following financial information reflects consolidating financial information of Southwestern Energy Company (the parent and issuer company), its Guarantor Subsidiaries on a combined basis and the Non-Guarantor Subsidiaries on a combined basis, prepared on the equity basis of accounting.  The information is presented in accordance with the requirements of Rule 3-10 under the SEC’s Regulation S-X.  The financial information may not necessarily be indicative of results of operations, cash flows or financial position had the Guarantor Subsidiaries operated as independent entities.

Natural gas and oil properties not subject to amortization represent investments in unproved properties and major development projects in which the Company owns an interest. These unproved property costs include unevaluated costs associated with leasehold or drilling interests and unevaluated costs associated with wells in progress.  The table below sets forth the composition of net unevaluated costs excluded from amortization as of December 31, 2019:2021:

Of the total net unevaluated costs excluded from amortization as of December 31, 2019,2021, approximately $1.2$1.1 billion is related to undeveloped properties in Southwest Appalachia (acquiredwhich were acquired in 2014 and 2015)2015, $117 million is related to Montage properties acquired in November 2020 and approximately $10$759 million is related to the acquisition of undeveloped properties in Northeast Appalachia.Haynesville which were acquired in September 2021 and December 2021.  Additionally, the Company has approximately $179$220 million of unevaluated capitalized interest and $95$51 million of unevaluated costs related to wells in progress.  The remaining costs excluded from amortization are related to properties which are not individually significant and on which the evaluation process has not been completed.  The timing and amount of property acquisition and seismic costs included in the amortization computation will depend on the location and timing of drilling wells, results of drilling and other assessments. The Company is, therefore, unable to estimate when these costs will be included in the amortization computation.

The results of operations shown above exclude general and administrative expenses and interest expense and are not necessarily indicative of the contribution made by the Company’s natural gas and oil operations to its consolidated operating results. Income tax expense is calculated by applying the statutory tax rates to the revenues less costs, including depreciation, depletion and amortization, and after giving effect to permanent differences and tax credits.
Natural Gas and Oil Reserve Quantities
The Company engaged the services of Netherland, Sewell & Associates, Inc., or NSAI, an independent petroleum engineering firm, to audit the reserves estimated by the Company’s reservoir engineers.  In conducting its audit, the engineers and geologists of NSAI studied the Company’s major properties in detail and independently developed reserve estimates.  NSAI’s audit consists primarily of substantive testing, which includes a detailed review of the Company’s major properties, and accounted for approximately 99% of the present worth of the Company’s total proved reserves as of December 31, 2021. For 2020 and 2019, NSAI’s audit accounted for 97% and 99%, respectively, of 2019, 2018 and 2017.the then-present worth of the Company’s total proved properties.  A reserve audit is not the same as a financial audit, and a reserve audit is less rigorous in nature than a reserve report prepared by an independent petroleum engineering firm containing its own estimate of reserves.  Reserve estimates are inherently imprecise, and the Company’s reserve estimates are generally based upon extrapolation of historical production trends, historical prices of natural gas and crude oil and analogy to similar properties and volumetric calculations.  Accordingly, the Company’s estimates are expected to change, and such changes could be material and occur in the near term as future information becomes available.  For more information over reserves, refer to the table titled “Changes in Proved Undeveloped Reserves (Bcfe)” in “Business – Exploration and Production” in Item 1 of this Annual Report.

Future cash inflows were reduced by estimated future production and development costs based on year-end costs to determine pre-tax cash inflows. Future income taxes were computed by applying the year-end statutory rate to the excess of pre-tax cash inflows over the Company’s tax basis in the associated proved gas and oil properties after giving effect to permanent differences and tax credits.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
None.
ITEM 9A. CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
We have performed an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act.Act as of the end of the period covered by this Annual Report. Our disclosure controls and procedures are the controls and other procedures that we have designed to ensure that we record, process, accumulate and communicate information to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures and submission within the time periods specified in the SEC’s rules and forms. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those determined to be effective can provide only a level of reasonable assurance with respect to financial statement preparation and presentation. Based on the evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of December 31, 20192021 at a reasonable assurance level.
There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended December 31, 2019,2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Management’s Report on Internal Control Over Financial Reporting is included on page 7279 of this Annual Report.
PricewaterhouseCoopers LLP’s report on Southwestern Energy’s internal control over financial reporting is included in its Report of Independent Registered Public Accounting Firm on page 7279 of this Annual Report.
ITEM 9B. OTHER INFORMATION
On February 24, 2020, the Compensation Committee of the Board of Directors of Southwestern Energy Company granted, subject to the approval of the Board, long-term incentives under the Company’s 2013 Incentive Plan, as amended (the “Plan”), to its principal executive officer, principal financial officer and other named executive officers. On February 25, 2020, the Company’s Board approved these grants.None.

The grants were comprised of two types of awards, the principal features of which are:ITEM 9C. DISCLOSURE REGARDING FOREIGN JURISDICTIONS THAT PREVENT INSPECTIONS

Restricted Stock Units. Each restricted stock unit that vests will entitle the holder to receive, payable in common stock or cash at the Compensation Committee’s option, a value based on an adjusted stock price, calculated as the sum of (1) the closing stock price on the date of grant and (2) 50% of the difference between (a) the closing stock price on the date of vesting and (b) the closing stock price on the date of grant. If paid in stock, in no event will the number of shares of common stock delivered to the Participant exceed the number of restricted stock units granted to the participant. 25% of the restricted stock units vest on each of the first through the fourth anniversaries of the date of grant, provided the grantee is still an employee of the Company on the vesting date; however, all restricted stock units vest in the case of the grantee’s Retirement, death or Disability or on a Change in Control, all as defined in the Plan.

Performance Units. Each performance unit that vests will entitle the holder to receive a value, payable in cash, based on the Company’s performance regarding specified metrics and on an adjusted stock price, as calculated above. The vesting date is the third anniversary of the date of grant, provided the grantee is still an employee of the Company on the vesting date; however, a pro rata portion of performance units vest in the case of the grantee’s Retirement, death or Disability, as defined in the Plan. Upon a Change in Control, as defined in the Plan, the performance period is deemed to end upon the change of control, and each unit granted vests at the greater of the adjusted stock price and the payment value based on the results of the performance measures. The determination of the value of each unit, 0-200%, is based on the achievement of threshold, target or maximum goals on the following metrics over a three-year performance period, being the calendar years 2020-2022:

50% Relative Total Shareholder Return – the difference between (a) the average of the closing prices for the Company’s common stock on the last 20 trading days of 2022 plus all dividends paid on account of one share of the Company’s common

stock and (b) the average of the closing prices for the last 20 trading days of 2019, as compared to the same calculation for a specified group of the Company’s peers.

50% Return on Average Capital Employed – calculated by dividing (i) the average of net cash provided by operating activities from the Consolidated Statement of Cash Flows less “changes in assets and liabilities” included in the Operating Activities section of the Consolidated Statement of Cash Flows for the performance period by the sum of (ii) the product of the twenty-day average stock price immediately prior to the first day of the performance period and the diluted weighted average number of shares of common stock of the Company outstanding for the fourth quarter of the year prior to the beginning of the performance period, (iii) gross debt of the Company (net of cash and cash equivalents) outstanding on December 31 of the year prior to the beginning of the performance period, and (iv) the sum of (a) the product of the number of shares of common stock the Company issued during the performance period and the price of said shares and (b) the amount of additional net debt incurred during the performance period, which sum shall then be reduced by (c) the amount by which any net debt is reduced during the performance period and (d) the product of the number of shares of common stock of the company purchased by the company during the performance period and the price of said shares, with each occurrence of the above in (a) – (d) multiplied by a fraction in which the denominator equals the total number of quarters in the Performance Period (12) and the numerator equals the remaining number of quarters following each occurrence of the above in (a) – (d) plus one.

Performance at target level for both metrics will result in a payout of 100%, and performance at maximum for both metrics entitles the holder to 200%. The Relative Total Shareholder Return portion will be deemed not to exceed the target level if absolute total shareholder return is negative.

William J. Way, President and Chief Executive Officer, was granted 1,863,500 of each type of award; Clay Carrell, Executive Vice President and Chief Operating Officer, was granted 883,440 of each type of award; Julian M. Bott, Executive Vice President and Chief Financial Officer, was granted 690,190 of each type of award; J. David Cecil, Executive Vice President, Corporate Development was granted 759,210 of each type of award; John C. Ale, Senior Vice President, General Counsel and Secretary, was granted 488,660 of each type of unit award.
