(Williams), a publicly traded Delaware corporation. Transco is a single member limited liability company, and as such, single member losses are limited to the amount of its investment.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Nature of Operations</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We are an interstate natural gas transmission company that owns and operates a natural gas pipeline system extending from Texas, Louisiana, Mississippi and the Gulf of Mexico through Alabama, Georgia, South Carolina, North Carolina, Virginia, Maryland, Delaware, Pennsylvania and New Jersey to the New York City metropolitan area. The system serves customers in Texas and the 12 southeast and Atlantic seaboard states mentioned above, including major metropolitan areas in Georgia, Washington D.C., Maryland, North Carolina, New York, New Jersey and Pennsylvania.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Basis of Presentation</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">These financial statements were prepared in accordance with the accounting requirements of the Federal Energy Regulatory Commission (FERC) as set forth in its Uniform System of Accounts and published accounting releases, which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States (GAAP). As a result, the following disclosures may not be consistent with our financial statements and notes thereto for the year ended December 31, 2022, in our Annual Report on Form 10-K. We have evaluated subsequent events through the date our financial statements were available to be issued on April 12, 2023.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The most significant difference between GAAP and the financial statements presented herein are: (1) the deferral of certain costs and revenues, (2) the classification of certain accounts in our financial statements, (3) the inclusion and classification of income taxes in a partnership’s or limited liability company’s financial statements, (4) purchase price allocations related to the acquisition of Transco by Williams in 1995, (5) lease accounting, and (6) impairment of certain projects.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The acquisition of Transco by Williams was accounted for using the purchase method of accounting and an allocation of the purchase price was assigned to our assets and liabilities based on their estimated fair values at the time of acquisition. The purchase price allocation to us primarily consisted of a $1.5 billion allocation to property, plant and equipment and adjustments to deferred taxes based upon the book basis of the net assets recorded as a result of the acquisition. However, our purchase price allocation assigned to property, plant and equipment and the related adjustments to deferred taxes and amortization are not reflected in the FERC financial statements included herein.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Use of Estimates</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The preparation of financial statements in conformity with the FERC regulatory basis of accounting requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Estimates and assumptions which, in the opinion of management, are significant to the underlying amounts included in the financial statements and for which it would be reasonably possible that future events or information could change those estimates include: 1) litigation-related contingencies; 2) environmental remediation obligations; 3) impairment assessments of long-lived assets; 4) depreciation; 5) asset retirement obligations; 6) measurement of regulatory assets and liabilities; and 7) deferred and other income taxes.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Revenue Recognition</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our customers are comprised of public utilities, municipalities, natural gas marketers and producers, intrastate pipelines, direct industrial users, and electric power generators.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Service revenue contracts from our gas pipeline business contain a series of distinct services, with the majority of our contracts having a single performance obligation that is satisfied over time as the customer simultaneously receives and consumes the benefits provided by our performance. Most of our natural gas sales contracts have a single performance obligation with revenue recognized at a point in time when the natural gas has been sold and delivered to the customer.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Certain customers reimburse us for costs we incur associated with construction of property, plant, and equipment utilized in our operations. We follow FERC guidelines with respect to reimbursement of construction costs. FERC tariffs only allow for cost reimbursement and are non-negotiable in nature; thus, in our judgment, the construction activities do not represent an ongoing major and central operation of our gas pipeline business and are not within the scope of Accounting Standards Codification (ASC) Topic 606, "Revenues from Contracts with Customers." Accordingly, cost reimbursements are treated as a reduction to the cost of the constructed asset.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"> Operating Revenues</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We are subject to regulation by certain state and federal authorities, including the FERC, with revenue derived from both firm and interruptible transportation and storage contracts. Firm transportation and storage agreements primarily provide for a fixed reservation charge based on the pipeline or storage capacity reserved, and a commodity charge based on the volume of natural gas delivered/stored, each at rates specified in our FERC tariffs or as negotiated with our customers, with contract terms that are generally long-term in nature. Most of our long-term contracts contain an evergreen provision, which allows the contracts to be extended for periods primarily up to one year in length an indefinite number of times following the specified contract term and until terminated generally by either us or the customer. Interruptible transportation and storage agreements provide for a volumetric charge based on actual commodity transportation or storage utilized in the period in which those services are provided, and the contracts are generally limited to one-month periods or less. Our performance obligations include the following:</span></div><div style="margin-top:10pt;padding-left:45pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Firm transportation or storage under firm transportation and storage contracts - an integrated package of services typically constituting a single performance obligation, which includes standing ready to provide such services and receiving, transporting or storing (as applicable), and redelivering commodities;</span></div><div style="margin-top:10pt;padding-left:45pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Interruptible transportation and storage under interruptible transportation and storage contracts - an integrated package of services typically constituting a single performance obligation once scheduled, which includes receiving, transporting or storing (as applicable), and redelivering commodities.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In situations where, in our judgment, we consider the integrated package of services as a single performance obligation, which represents a majority of our contracts with customers, we do not consider there to be multiple performance obligations because the nature of the overall promise in the contract is to stand ready (with regard to firm transportation and storage contracts), receive, transport or store, and redeliver natural gas to the customer; therefore, revenue is recognized over time upon satisfaction of our daily stand ready performance obligation.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We recognize revenues for reservation charges over the performance obligation period, which is the contract term, regardless of the volume of natural gas that is transported or stored. Revenues for commodity charges from both firm and interruptible transportation services and storage services are recognized when natural gas is delivered at the agreed upon delivery point or when natural gas is injected or withdrawn from the storage facility because they specifically relate to our efforts to provide these distinct services. Generally, reservation charges and commodity charges are recognized as revenue in the same period they are invoiced to our customers. As a result of the ratemaking process, certain amounts collected by us may be subject to refunds upon the issuance of final orders by the FERC in pending rate proceedings. We use judgment to record estimates of rate refund liabilities considering our and other third-party regulatory proceedings, advice of counsel, and other risks. At December 31, 2022 and 2021, we had no such rate refund liabilities.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"> Natural Gas Sales</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In the course of providing transportation services to customers, we may receive different quantities of natural gas from customers than the quantities delivered on behalf of those customers. The resulting imbalances are primarily settled through the purchase or sale of natural gas with each customer under terms provided for in our FERC tariffs. Revenue is recognized from the sale of natural gas upon settlement of the transportation and exchange imbalances (see Gas Imbalances below).</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"> </span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Contract Liabilities</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our contract liabilities consist of advance payments from customers, which include prepayments, and other billings for which future services are to be provided under the contract. These amounts are deferred until recognized in revenue when the associated performance obligation has been satisfied, which is primarily straight-line over the remaining contractual service periods, and are classified as current or non-current according to when such amounts are expected to be recognized.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Contracts requiring advance payments and the recognition of contract liabilities are evaluated to determine whether the advance payments provide us with a significant financing benefit. This determination is based on the combined effect of the expected length of time between when we transfer the promised good or service to the customer, when the customer pays for those goods or services and the prevailing interest rates. We have assessed our contracts and determined none of our contracts contain a significant financing component.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Environmental Matters</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We are subject to federal, state, and local environmental laws and regulations. Environmental expenditures are expensed or capitalized depending on their economic benefit and potential for rate recovery. We believe that expenditures required to meet applicable environmental laws and regulations are prudently incurred in the ordinary course of business and such expenditures would be permitted to be recovered through rates with limited exceptions.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Property, Plant and Equipment</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Property, plant and equipment is recorded at cost. The carrying values of these assets are also based on estimates, assumptions and judgments relative to capitalized costs, useful lives and salvage values. These estimates, assumptions and judgments reflect FERC regulations, as well as historical experience and expectations regarding future industry conditions and operations. The FERC identifies installation, construction and replacement costs that are to be capitalized. All other costs are expensed as incurred. Gains or losses from the ordinary sale or retirement of property, plant and equipment are credited or charged to accumulated depreciation; certain other gains or losses are recorded in operating income.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We provide for depreciation under the composite (group) method using the straight-line method at FERC prescribed rates that are applied to the cost of the group for transmission facilities, production and gathering facilities and storage facilities. Under this method, assets with similar lives and characteristics are grouped and depreciated as one asset. Included in our depreciation rates is a negative salvage component (net cost of removal) that we currently collect in rates. Our depreciation rates are subject to change each time we file a general rate case with the FERC.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We record a liability and increase the basis in the underlying asset for the present value of each expected future Asset Retirement Obligation (ARO) at the time the liability is initially incurred, typically when the asset is acquired or constructed. Measurements of AROs include, as a component of future expected costs, an estimate of the price that a third party would demand, and could expect to receive, for bearing the uncertainties inherent in the obligations, sometimes referred to as a market-risk premium. The ARO asset is depreciated in a manner consistent with the expected timing of the future abandonment of the underlying physical assets. We measure changes in the liability due to passage of time by applying an interest method of allocation. The depreciation of the ARO asset and accretion of the ARO liability are recognized as an increase to a regulatory asset, as management expects to recover such amounts in future rates. The regulatory asset is amortized commensurate with our collection of these costs in rates.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Allowance for Funds Used During Construction</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Allowance for funds used during construction (AFUDC) represents the estimated cost of borrowed and equity funds applicable to utility plant in process of construction and are included as a cost of property, plant and equipment because it constitutes an actual cost of construction under established regulatory practices. The FERC has prescribed a formula to be used in computing separate allowances for borrowed and equity AFUDC. The </span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">allowance for borrowed funds used during construction was $5.2 million and $5.0 million, for 2022 and 2021, respectively. The allowance for equity funds was $23.0 million and $17.1 million, for 2022 and 2021, respectively.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Income Taxes</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Williams and its wholly-owned subsidiaries, which includes us, file a consolidated federal income tax return. It is Williams' policy to charge or credit its taxable subsidiaries with an amount equivalent to their federal income tax expense or benefit computed as if each subsidiary had filed a separate return.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As a limited liability company, Transco is no longer a taxable entity for income tax purposes; however, amounts equivalent to current and deferred income tax expense based on corporate tax rates are presented in the accompanying financial statements since income taxes are a cost component for Transco’s currently effective rates.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We use the assets and liabilities method of accounting for income taxes, which requires, among other things, provisions for all temporary differences between the financial basis and the tax basis in our assets and liabilities and adjustments to the existing deferred tax balances for changes in tax rates. Future cash distributions to our member will be allocated between income taxes payable by member and equity distribution and will be recorded as a reduction to income taxes payable and equity based on that allocation.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Accounts Receivable</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Accounts receivable are carried on a gross basis, with no discounting, less an allowance for doubtful accounts. We estimate the allowance for doubtful accounts, considering current expected credit losses using a forward-looking "expected loss" model, the financial condition of our customers, and the age of past due accounts. The majority of our trade receivable balances are due within 30 days. We monitor the credit quality of our counterparties through review of collection trends, credit ratings, and other analyses, such as bankruptcy monitoring, if applicable. Financial assets are evaluated as one pool. Changes in counterparty risk factors could lead to reassessment of the composition of our financial assets as one pool. We calculate our allowance for credit losses incorporating an aging method. In estimating our expected credit losses, we utilized historical loss rates over many years. Our expected credit loss estimate considered both internal and external forward-looking commodity price expectations, as well as counterparty credit ratings, and factors impacting their near-term liquidity.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We do not offer extended payment terms and typically receive payment within one month. We consider receivables past due if full payment is not received by the contractual due date. Past due accounts are generally written off against the allowance for doubtful accounts only after all collection attempts have been exhausted. We do not have a material amount of significantly aged receivables at December 31, 2022 and 2021. The balance of our allowance for doubtful accounts at December 31, 2022 and December 31, 2021 was zero and $6.3 million, respectively. The balance at December 31, 2021 was primarily related to non-trade receivables.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Gas Imbalances</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In the course of providing transportation services to customers, we may receive different quantities of gas from shippers than the quantities delivered on behalf of those shippers. Additionally, we transport gas on various pipeline systems which may deliver different quantities of gas on behalf of us than the quantities of gas received from us. These transactions result in gas transportation and exchange imbalance receivables and payables which are recovered or repaid in cash (see Deferred Cash Out below) or through the receipt or delivery of gas in the future and are recorded in the accompanying Balance Sheet. Settlement of imbalances requires agreement between the pipelines and shippers as to allocations of volumes to specific transportation contracts and timing of delivery of gas based on operational conditions. Our tariff includes a method whereby most transportation imbalances are settled on a monthly basis. Each month a portion of the imbalances are not identified to specific parties and remain unsettled. These are generally identified to specific parties and settled in subsequent periods. We believe that amounts that remain unidentified to specific parties and unsettled at year end are valid balances that will be settled with no material adverse effect upon our financial position, results of operations or cash flows. Management has implemented a policy of continuing to carry any unidentified transportation and exchange imbalances on the books for a three-year period. At the end of the three-year period a final assessment will be </span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">made of their continued validity. Absent a valid reason for maintaining the imbalance, any remaining balance will be recognized in income. Certain imbalances are being recovered or repaid in cash or through the receipt or delivery of gas upon agreement of the parties as to the allocation of the gas volumes, and as permitted by pipeline operating conditions. These imbalances have been classified as current assets and current liabilities at December 31, 2022 and 2021. We utilize the average cost method of accounting for gas imbalances.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Deferred Cash Out</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Most transportation imbalances are settled in cash on a monthly basis (cash-out). In accordance with our tariff, revenues received from the cash-out of transportation imbalances in excess of costs incurred are deferred and offset by the deferral of costs incurred in excess of revenues received. At the end of each annual August through July reporting period, if the cumulative revenues received exceed the costs incurred, the over recovered amounts are applied to any prior under recovery balance or refunded. If the cumulative revenues received are less than the costs incurred, the net under recovered amounts are carried forward and offset against any future net over recoveries that may occur in a subsequent annual reporting period.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Materials and Supplies Inventory</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">All materials and supplies inventory is stated at average cost. We perform an annual review of materials and supplies inventories, including a quarterly analysis of parts that may no longer be useful due to planned replacements of compressor engines and other components on our system. Based on this assessment, we record a reserve for the value of the inventory which can no longer be used for maintenance and repairs on our pipeline. There was a minimal reserve at December 31, 2022 and 2021.</span></div><div style="margin-top:10pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Contingent Liabilities</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We record liabilities for estimated loss contingencies, including environmental matters, when we assess that a loss is probable and the amount of the loss can be reasonably estimated.

For such long-lived assets, an impairment exists when its carrying value exceeds the sum of estimates of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. When alternative courses of action to recover the carrying amount of a long-lived asset are under consideration, a probability-weighted approach is used in developing estimates of future undiscounted cash flows. If the carrying value of the long-lived asset is not recoverable based on these estimated future undiscounted cash flows, an impairment loss is measured as the excess of the asset’s carrying value over its fair value, such that the asset’s carrying value is adjusted to its estimated fair value. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">We assess the fair value of long-lived assets using commonly accepted techniques and may use more than one source.

federal and state income tax purposes. As a result, Southwest Gas obtained a step-up in the bases of the assets acquired for income tax purposes, without succeeding to the holding period, accounting methods, or historical income tax liabilities associated with MountainWest Pipeline. The acquisition by Southwest Gas resulted tax-deductible goodwill. Because the book basis of goodwill was not pushed down to MountainWest Pipeline, a deferred tax asset was recorded for the temporary difference which will be amortized over 15 years. During 2022, a measurement period adjustment was recorded resulting in $9.1 million of additional deferred taxes that were recorded as a non-cash equity contribution.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">MountainWest Pipeline files U.S. federal and state income tax returns in jurisdictions with varying statutes of limitations.

Prior to its change in parent, MountainWest Pipeline reported an estimate of ARO liabilities associated with the interim replacement of pipeline components on its consolidated balance sheets, based on projected cash flows, including projected usage and maintenance of its assets. In connection with the acquisition of MountainWest Pipeline by Southwest Gas, new management assessed the information available to develop an estimate. Factors assessed included indeterminant interim removal dates based on maintenance of the entity’s assets, management’s expected use of the assets in place, and expectations around renewal of easements and rights of way. On the basis of this evaluation, new management concluded that it did not possess information of sufficient precision to reasonably estimate the ARO liability. New management’s assessment is viewed as a change in estimate.</span></div><div><span><br/></span></div><div><span

One new rulemaking establishing a methane performance program for the natural gas transmission and storage sector has been finalized that could have a material impact on MountainWest Pipeline. In December 2020, MountainWest Pipeline implemented a methane best management practices plan and began collecting emissions inventory information for its facilities in Colorado which is submitted annually. The CDPHE will evaluate greenhouse gas reduction performance from the transmission and storage sector to determine if additional requirements will be necessary to meet the state’s goals. At this time, the CDPHE has not determined whether additional rulemaking related to the best management practices plan is needed. As a result, MountainWest Pipeline is unable to determine if potential impacts on its results of operations, financial condition and/or cash flows related to this matter will be material.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:107%">In another rulemaking finalized in December 2021, the CDPHE amended certain regulations that, among other things, establishes a steering committee to develop recommendations for the reduction of greenhouse gas emissions from combustion sources in the midstream segment of Colorado’s oil and natural gas industry. MountainWest Pipeline has natural gas processing facilities which are part of this midstream segment and could be impacted by this rule. This steering committee is directed to consider all means of reducing greenhouse gas emissions, including the electrification of fuel-burning engines. The steering committee is required to publish its guidelines in 2023, after which the CDPHE is expected to establish requirements for reducing greenhouse gas emissions from these combustion sources MountainWest Pipeline cannot determine whether potential impacts on its results of operations, financial condition and/or cash flows related to this matter will be material.</span></div><div style="margin-top:12pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Surety Bonds</span></div><div style="margin-top:12pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">At December 31, 2022, MountainWest Pipeline had purchased $5.1 million of surety bonds.

At December 31, 2022 and 2021, the provision for credit losses was $0.0 million and $0.3 million, respectively.
