The Partnership maintains an allowance for doubtful accounts for estimated losses on accounts receivable, if it is determined the Partnership will not collect all or part of the outstanding receivable balance. The Partnership regularly reviews its allowance for doubtful accounts and establishes or adjusts the allowance as necessary using the specific‑identification method. Account balances are charged to the allowance after all means of collection have been exhausted and the potential for recovery is no longer considered probable. There were no accounts charged to the allowance as of December 31, 2022 and 2021.</span></div><div style="margin-bottom:6pt;padding-left:36pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:700;line-height:120%">e.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:700;line-height:120%;padding-left:8pt">Natural Gas Imbalances</span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">Natural gas imbalances occur when the actual amount of natural gas delivered to or received from a pipeline system differs from the amount of natural gas scheduled to be delivered or received.

Under this method, assets with similar lives and characteristics are grouped and depreciated as one asset. The depreciation rate is applied to the total cost of the group until its net book value equals its salvage value. All asset groups are depreciated using depreciation rates approved in the Partnership’s last rate proceeding. Currently, the Partnership’s depreciation rates vary from 2 percent to 20 percent per year. Using these rates, the remaining depreciable life of these assets ranges from less than 1 year to 49 years. Depreciation rates are reevaluated each time the Partnership files with the FERC for a change in its transportation service rates.</span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">When property, plant and equipment are retired, the Partnership charges accumulated depreciation and amortization for the original cost of the assets in addition to the cost to remove, sell, or dispose of the assets, less their salvage value. The Partnership does not recognize a gain or loss unless an entire operating unit is sold or retired. The Partnership includes gains or losses on dispositions of operating units in income.</span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">The Partnership capitalizes a carrying cost on funds invested in the construction of long-lived assets.

Capitalized AFUDC equity amounts are included as other income in the statements of income. Debt amounts capitalized during the years ended December 31, 2022 and 2021 were $0.2 million and $0.7 million, respectively. Equity amounts capitalized during the years ended December 31, 2022 and 2021 were $0.6 million and $5.1 million, respectively.

Revenues earned from firm contracted capacity arrangements are recognized ratably over the term of the contract regardless of the amount of natural gas that is transported. Transportation revenues for interruptible or volumetric-based services are recognized when the service is performed. The Partnership utilizes the practical expedient of recognizing revenue as invoiced. Revenues are invoiced and paid on a monthly basis. The Partnership’s pipeline system does not take ownership of the natural gas that is transported for customers. Revenues from contracts with customers are recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities.</span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">The Partnership's pipeline system is subject to FERC regulations and, as a result, a portion of revenues collected may be subject to refund if invoiced during an interim period when a rate proceeding is ongoing. Allowances for these potential refunds are recognized using management's best estimate based on the facts and circumstances of the proceeding. Any allowances that are recognized during the proceeding process are refunded or retained, as applicable, at the time a regulatory decision becomes final. As of December 31, 2022 and 2021 there are no refund provisions reflected in these financial statements. </span></div><div style="margin-bottom:6pt;padding-left:36pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:700;line-height:120%">h.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:700;line-height:120%;padding-left:7.34pt">Accounting for Asset Retirement Obligations</span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">The Partnership accounts for asset retirement obligations pursuant to the provisions of Accounting Standards Codification (ASC) 410-20, </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:400;line-height:120%">Asset Retirement Obligations</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">. ASC 410-20 requires the Partnership to record the fair value of an asset retirement obligation as a liability in the period in which it incurs a legal obligation associated with the retirement of tangible long lived assets that result from the acquisition, construction, development, and/or normal use of the assets. ASC 410-20 also requires the Partnership to record a corresponding asset that is depreciated over the life of the asset. Subsequent to the initial measurement of the asset retirement obligation, the obligation is to be adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows underlying the obligation.</span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">The fair value of a liability for an asset retirement obligation is recorded during the period in which the liability is incurred, if a reasonable estimate of fair value can be made. The Partnership has determined that asset retirement obligations exist for certain of its transmission assets; however, the fair value of the obligations cannot be determined </span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">because the end of the transmission system’s life is not determinable with the degree of accuracy necessary to currently establish a liability for the obligations.</span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">The Partnership has determined it has legal obligations associated with its natural gas pipeline and related transmission facilities. The obligations relate primarily to purging and sealing the pipeline if it is abandoned. The Partnership is also required to operate and maintain its natural gas pipeline system and intends to do so as long as supply and demand for natural gas exists, which the Partnership expects for the foreseeable future. Therefore, the Partnership believes its natural gas pipeline system assets have indeterminate lives and, accordingly, has recorded no asset retirement obligation as of December 31, 2022 and 2021. The Partnership continues to evaluate its asset retirement obligations and future developments that could impact amounts it records.</span></div><div style="margin-bottom:6pt;padding-left:36pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:700;line-height:120%">i.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:700;line-height:120%;padding-left:11.34pt">Income Taxes</span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">Income taxes are not normally reflected in the financial statements of limited partnerships. The FERC’s 2005 Income Tax Policy Statement allowed pass through entities, such as the Partnership, to recover an income tax allowance, therefore, the Partnership recognized pro-forma income taxes on its records. On January 1, 2018, the Partnership adopted FERC’s Revised Policy Statement on Treatment of Income Taxes (Revised Policy Statement) issued on March 15, 2018 along with subsequent guidance issued on July 18, 2018. As a result, effective January 1, 2018, the Partnership prospectively eliminated its income tax allowance, along with its Accumulated Deferred Income Taxes (ADIT) used for rate-making purposes and tax related regulatory assets and liabilities. </span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">On March 3, 2021, the Partnership’s parent, TCP, merged into TC Energy through a share for unit exchange taxable transaction whereby TC Energy issued and exchanged 0.70 TC Energy shares for every TCP common unit not beneficially owned by TC Energy. TCP was previously a publicly traded partnership and now the Partnership is indirectly wholly owned by corporate entities. As a result, the post-merger associated tax impacts applied on March 3, 2021 were recognized by the Partnership to reflect the difference between the book basis of the Partnership’s assets and their tax basis which included a step up as a result of the taxable transaction. This one-time adjustment resulted in an increase in the Partnership’s ADIT balance (190) amounting to $16,083,467, an increase in ADIT - Other Property (282) amounting to $21,497,785 and a corresponding offset to Other Paid-In Capital (211) amounting to $5,414,318.</span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">Additionally, beginning March 3, 2021 the Partnership will record income taxes in accordance with the Revised Policy Statement on Income Tax Allowances permitting the accrual of income taxes on pass-through entities and associated taxes accrued are treated as deemed contributions/distributions recorded in Other Paid in Capital. Deferred income taxes are recognized for differences between the financial reporting and tax basis of assets and liabilities at enacted statutory tax rates in effect for the years in which the differences are expected to reverse. Actual income taxes could vary from these estimates due to future changes in income tax law or results from the final review of tax returns by federal or state tax authorities.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:700;line-height:120%"> </span></div><div style="margin-bottom:6pt;padding-left:36pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:700;line-height:120%">j.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:700;line-height:120%;padding-left:11.34pt">Fair Value Measurement</span></div><div style="margin-bottom:6pt;padding-left:18pt;text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">For cash and cash equivalents, receivables, accounts payable and certain accrued expenses, the carrying amount approximates fair value due to the short maturities of these instruments.

For regulated businesses subject to federal cost-of-service rate regulation, regulatory practices that assign costs to accounting periods may differ from accounting methods generally applied by non-regulated companies. When it is probable that FERC will permit the recovery of current costs through future rates charged to customers, these costs that otherwise would be expensed by non-regulated companies are deferred as regulatory assets. Likewise, regulatory liabilities are recognized when it is probable that FERC will require customer refunds through future rates or when revenue is collected from customers for expenditures that have yet to be incurred. </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:112%">MountainWest Pipeline evaluates whether or not recovery of its regulatory assets through future rates is probable as well as whether a regulatory liability due to customers is probable and makes various assumptions in its analyses.

Quarterly, MountainWest Pipeline assesses their AROs to determine if circumstances indicate that estimates of the amounts or timing of future cash flows associated with retirement activities have changed. AROs are adjusted when significant changes in the amounts or timing of future cash flows are identified.

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.

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.

Revenues related to these services provided but not yet billed are estimated each month. These estimates are generally based on contract data, regulatory information, and preliminary throughput and allocation measurements. Final bills for the current month are billed and collected in the following month.

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.

White River Hub may collect revenues subject to possible refunds and establish reserves pending final orders from FERC.

Substantially all of White River Hub’s revenues are derived from performance obligations satisfied over time, rather than recognized at a single point in time. The contract with the customer states the final terms of the sale, including the description, quantity and price of each product or service purchased.

One new rulemaking establishing a methane performance program for the natural gas transmission and storage compressor sector has been finalized that could have a material impact on White River Hub. In December 2020, Respondent implemented a methane best management plan and began collecting emissions inventory information for facilities in Colorado which will be 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.
