These estimates and assumptions affect the amounts reported for assets, liabilities, revenues, and expenses during the reporting period, and the disclosure of contingent assets and liabilities at the date of the financial statements. Management evaluates these estimates on an ongoing basis, utilizing historical experience, consultation with experts and other methods it considers reasonable in the particular circumstances. Nevertheless, actual results may differ significantly from these estimates. These estimates and other factors, including those outside of TIGT's control, such as the impact of sustained lower commodity prices and volatility associated with the COVID-19 pandemic, could have a significant adverse impact on its business, financial position, or results of operations. Any impact of revisions to these estimates is recorded in the period in which the facts that give rise to the revision become known.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Cash Equivalents and Supplemental Cash Flow Information</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">TIGT considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. </span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Non-cash investing activities during the years ended December 31, 2021 and 2020 include accruals of property, plant, and equipment of $0.5 million and $0.6 million, respectively.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Accounts Receivable and Reserves for Credit Losses</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments–Credit Losses (Topic 326).

Current expected credit losses for trade receivables are estimated using a combination of the probability-of-default methodology and review of aging schedules. Trade receivables are measured collectively, with customers grouped on the basis of their credit profile and line of business, and consideration is given to individual receivables that may have different risk profiles. Probability of default rates are assigned to customers based on actual credit ratings or estimated ratings based on available financial metrics. Outstanding receivables are periodically reviewed and for any specific receivables deemed uncollectible, a reserve for current expected credit losses is recorded. TIGT's reserve for current expected credit losses totaled $0.7 million at December 31, 2021 and 2020.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Fuel Recovery Mechanism</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">TIGT obtains natural gas quantities from its shippers as reimbursement for fuel consumed at compressor stations and other locations on its system as well as for natural gas quantities lost and otherwise unaccounted for, in accordance with its tariff and applicable contract terms. TIGT tracks the volume and value of associated over- or under-collections of fuel and lost and unaccounted for quantities through a tracking mechanism referred to as "fuel tracker." Those amounts are recorded as an addition or reduction to a regulatory asset or liability balance representing the amounts to be recovered from or refunded to customers through the fuel tracker mechanisms. Fuel tracker volumes are valued using an average monthly index price.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Accounting for Regulatory Activities</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Regulatory assets and liabilities represent probable future revenues or expenses to TIGT associated with certain charges and credits that will be recovered from or refunded to customers through the ratemaking process. TIGT recorded regulatory assets (Account 182.3, Other Regulatory Assets) of $1.9 million and $0.9 million at December 31, 2021 and 2020, which were primarily attributable to costs associated with TIGT's fuel and power trackers, the remeasurement of TIGT's deferred income tax asset, as discussed further in Note 3 -</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;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%">Income Taxes, and costs associated with TIGT's rate case filing. TIGT recorded regulatory liabilities (Account 254, Other Regulatory Liabilities) of $3.8 million and $0.5 million at December 31, 2021 and 2020. The regulatory liabilities as of December 31, 2021 were primarily attributable to penalties associated with operational flow orders that will be refunded to shippers pursuant to Section 34 of the General Terms and Conditions of the Tariff and the regulatory liabilities as of December 31, 2020 were primarily attributable to fuel and power trackers.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Gas in Underground Storage</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Gas in underground storage represents the cost of base gas and cushion gas, which refers to the volumes necessary to maintain pressure and deliverability requirements in TIGT's storage facilities.

TIGT receives a fee for its storage services but does not reflect the value of third party gas in the accompanying financial statements. TIGT occasionally acquires volumes of working gas for its own account. These volumes of working gas are recorded at the lower of cost or net realizable value as a component of Account 117.4, Gas Owed to System Gas. </span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Gas Imbalances</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Gas imbalances receivable and payable represent the difference between customer nominations and actual gas receipts from and gas deliveries to interconnecting pipelines under various operational balancing and imbalance agreements. Gas imbalances are either made up in-kind or settled in cash, subject to the terms of the various agreements. Imbalances are valued at applicable average market index prices of $3.31 per MMBtu and $2.33 per MMBtu at December 31, 2021 and 2020, respectively.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Property, Plant and Equipment</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Utility Plant is stated at historical cost, which for constructed plant includes indirect costs such as payroll taxes, other employee benefits, allowance for funds used during construction and other costs directly related to the projects. Expenditures that increase capacities, improve efficiencies or extend useful lives are capitalized and depreciated over the remaining useful life of the asset or major asset component. TIGT also capitalizes certain costs related to the construction of assets, including internal labor costs, interest and engineering costs.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Routine maintenance, repairs and renewal costs are expensed as incurred. The cost of normal retirements of depreciable utility property, plant and equipment, plus the cost of removal less salvage value and any gain or loss recognized, is recorded in accumulated depreciation with no effect on current period earnings. Gains or losses are recognized upon retirement of utility property, plant and equipment constituting an operating unit or system, and land, when sold or abandoned and costs of removal or salvage are expensed when incurred.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">TIGT maintains natural gas in its pipeline, known as "line pack," which serves to maintain the necessary pressure to allow efficient transmission of natural gas.

The annual composite rate of depreciation for the years ended December 31, 2021 and 2020 ranges from 1.22% to 25.0% for the various classes of depreciable assets. These depreciation rates include two components, one based on economic service life (capital recovery) and one based on net costs of removal (negative salvage).</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Impairment of Long-Lived Assets </span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:115%">TIGT reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss results when the estimated undiscounted future net cash flows expected to result from the asset's use and its eventual disposition are less than its carrying amount. Any such impairment losses at TIGT would be recorded as a regulatory asset until regulatory review regarding recoverability through the rate-making process is complete, at which time TIGT will recognize the loss if it is determined to be unrecoverable or retain as a regulatory asset and recover through its rates.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Examples of long-lived asset impairment indicators include:</span></div><div style="margin-bottom:6pt;margin-top:6pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;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:13.8pt">a significant decrease in the market value of a long-lived asset or group;</span></div><div style="margin-bottom:6pt;margin-top:6pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;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:13.8pt">a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition;</span></div><div style="margin-bottom:6pt;margin-top:6pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;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:13.8pt">a significant adverse change in legal factors or in the business climate could affect the value of a long-lived asset or asset group, including an adverse action or assessment by a regulator which would exclude allowable costs from the rate-making process;</span></div><div style="margin-bottom:6pt;margin-top:6pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;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:13.8pt">an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of the long-lived asset or asset group;</span></div><div style="margin-bottom:6pt;margin-top:6pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;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:13.8pt">a current period operating cash flow loss combined with a history of operating cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group; and</span></div><div style="margin-bottom:6pt;margin-top:6pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;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:13.8pt">a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">When an impairment indicator is present, TIGT first assesses the recoverability of the long-lived assets by comparing the sum of the undiscounted future cash flows expected to result from the use and eventual disposition of the asset to the carrying amount of the asset.

Under the five-step model, TIGT identifies the contract, identifies the performance obligations, determines the transaction price, allocates the transaction price, and recognizes revenue. Revenue is recognized when (or as) the performance obligations are satisfied.

When a range of probable loss can be estimated, TIGT accrues the most likely amount, or if no amount is more likely than another, TIGT accrues the minimum of the range of probable loss.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Environmental Costs</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">TIGT expenses or capitalizes, as appropriate, environmental expenditures that relate to current operations. TIGT expenses amounts that relate to an existing condition caused by past operations that do not contribute to current or future revenue generation. TIGT does not discount environmental liabilities to a net present value, and records environmental liabilities when environmental assessments and/or remedial efforts are probable and costs can be reasonably estimated. Recording of these accruals coincides with the completion of a feasibility study or a commitment to a formal plan of action. Estimates of environmental liabilities are based on currently available facts and presently enacted laws and regulations taking into consideration the likely effects of other factors including prior experience in remediating contaminated sites, other companies' clean-up experience and data released by government organizations. TIGT's estimates are subject to revision in future periods based on actual cost or new information.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Income Taxes</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Deferred income tax assets and liabilities are recognized for temporary differences between the basis of assets and liabilities for financial reporting and tax purposes. Changes in tax legislation are included in the relevant computations in the period in which such changes are effective.

As a disregarded entity, TIGT's annual taxable income or loss is included in the tax return filed by a parent entity. The parent entity is a limited partnership subject to pass-through treatment for federal and state income tax purposes. Although TIGT does not directly pay federal or state income taxes, it has historically been allowed to treat the income tax paid by the ultimate owners of TEP as a cost component in rates allowed by the FERC. These taxes are calculated based on the composite federal and state tax rates of the ultimate owners of TEP and included in the applicable financial statements herein. On March 15, 2018, in Docket No. PL17-1-000, the FERC issued a revised Policy Statement finding that interstate natural gas pipelines held by Master Limited Partnerships are no longer permitted to recover an income tax allowance in their cost of service. The FERC stated that it would address income tax allowances for other pass-through entities that are not Master Limited Partnerships in future proceedings. In July 2018, the FERC issued Order 849, which required interstate natural gas pipelines to make a one-time informational filing of Form No. 501-G to evaluate the impact of the Tax Cuts and Jobs Act ("TCJA") and the Revised Policy Statement on interstate natural gas pipelines' revenue requirement. In August and November 2018, the FERC issued additional guidance in Docket Nos. AC18-115 and PL19-2 regarding the treatment of accumulated deferred income taxes for both accounting and ratemaking purposes in light of the TCJA.

performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC Topic 606. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of TIGT's contracts have a single performance obligation and are billed and collected monthly. These performance obligations typically include an obligation to stand ready to provide natural gas transportation, storage, or an integrated transportation and storage service over the life of the contract, which is a series. These performance obligations are satisfied over time using each day of service to measure progress toward satisfaction of the performance obligation.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">TIGT also engages in commodity sales, in which the performance obligations include an obligation to deliver the specified volume of a commodity to the designated receipt point.

Recourse rates are calculated based on the cost of service being provided and include an allowable rate of return for the pipeline. Recourse rates are established through a FERC rate proceeding and remain effective until a subsequent rate proceeding is filed and approved by the FERC. Discount rates are offered at a discount to the then-effective maximum recourse rate, subject to a minimum rate floor set forth in the pipeline's tariff. Discount rates are typically effective for an established term and can vary based on adjustments to the underlying recourse rate. Negotiated rates can be higher or lower than the then-effective maximum recourse rate, subject to agreement between the pipeline and shipper and approval by the FERC. Negotiated rates are also entered into for a defined term but do not change based on adjustments in the applicable recourse rate for that type of service.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Currently, there are no regulatory proceedings challenging the transportation rates of TIGT.</span></div><div style="margin-bottom:6pt;margin-top:6pt;padding-left:18pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">9.

The financial statements presented herein have been prepared in accordance with the accounting requirements of the FERC, as set forth in the applicable Uniform System of Accounts (USOA) and published accounting releases, which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America (U.S. GAAP). Our accounting policies generally conform to the FERC USOA. The most significant differences between U.S. GAAP and the financial statements presented herein are: (1) classification of certain accounts on the Comparative Balance Sheet, Statement of Income and the Statement of Cash Flows and (2) accounting for income taxes on a regulatory basis using the stand-alone method of income tax allocation.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Use of Estimates</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">.

Although these estimates are based on our best available knowledge at the time, actual results could differ.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%"> </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Fair Value Measurements. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">Nautilus measures the fair value of financial assets and liabilities by maximizing the use of observable inputs and minimizing the use of unobservable inputs. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value of cash and cash equivalents, accounts receivable and accounts payable are not materially different from their carrying amounts because of the short-term nature of these instruments or because stated rates approximate market rates.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Cost-Based Regulation. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%"> Nautilus accounts for its regulated operations under the provisions of the USOA. The economic effects of regulation can result in a regulated company recording assets for costs that have been or are expected to be approved for recovery from customers or recording liabilities for amounts that are expected to be returned to customers in the rate-setting process in a period different from the period in which the amounts would be recorded by an unregulated enterprise. Accordingly, assets and liabilities recorded as a result of the regulated ratemaking process may not be recorded under U.S. GAAP for non-regulated entities. Nautilus continually assesses whether regulatory assets are probable of future recovery by considering factors such as applicable regulatory changes and recent rate orders to other regulated entities. Based on this assessment, Nautilus believes existing regulatory assets are probable of recovery. These regulatory assets and liabilities are classified in the Comparative Balance Sheet as “Deferred Debits” and “Deferred Credits.” </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Revenue Recognition. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">Revenues from the transportation of natural gas are recognized when the service has been performed, the amount of revenue can be reliably measured and collectability is reasonably assured. 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. Nautilus does not own the natural gas that it transports and, therefore, it does not assume significant direct commodity price risk. See Note 3 for further discussion.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%"> </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Accumulated Provision for Uncollectible Accounts - Credit.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%"> Accounts receivable are measured at cost. Accumulated Provision for Uncollectible Accounts - Credit (account 144) is determined based on current expected credit losses. When we have determined that further collection efforts are unlikely to be successful, amounts are charged to this account and are applied against the impaired Customer Accounts Receivable (account 142).</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Allowance for Funds Used During Construction (AFUDC). </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">AFUDC, which represents the estimated debt and equity costs of capital funds necessary to finance the construction of certain new regulated facilities, consists of two components, an equity component and an interest expense component. The equity component is a non-cash item. After construction is completed, we are permitted to recover these costs through inclusion in the rate base and in the depreciation provision.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Income Taxes. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">Nautilus, as a limited liability company, is not subject to federal taxation. Instead, the tax obligation incurred through operations of Nautilus is reported on the tax returns of the member companies. However, in accordance with FERC accounting and rate requirements, the accompanying financial statements include entries to reflect income taxes as if Nautilus was a corporation. Deferred taxes are recognized for temporary differences between the relevant basis of the assets and liabilities for financial reporting and tax purposes.

The carrying value of cash and cash equivalents approximates fair value because of the short-term maturity of these investments. Cash is held in major banks in the U.S., which from time to time may exceed federally insured limits in the U.S. Management periodically assesses the financial condition of the financial institution and believes that any possible credit loss is minimal.</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%">Nautilus has entered in a cash management agreement with Neptune, whereas all cash is held in bank accounts of Neptune.

These transactions result in imbalances, which are settled in cash on a monthly basis. In addition, certain imbalances may occur with interconnecting facilities when Nautilus delivers more or less than what is nominated (scheduled). The settlement of these imbalances is governed by Operational Balancing Agreements (OBAs). Certain OBAs stipulate that settlement will occur through delivery of physical quantities in subsequent months. Nautilus records the net of all imbalances as Gas Operating Revenues and carries the net position for each counterparty as a payable or receivable, as appropriate, and settled.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Utility Plant. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">Utility Plant is stated at the original cost of construction or, upon acquisition, at the fair value of the assets acquired. Expenditures for system expansion and major renewals and betterments are capitalized; maintenance and repair costs are expensed as incurred. Nautilus follows the practice of capitalizing, at rates authorized by the FERC or stipulated in ratemaking agreements, an allowance for funds used during construction (AFUDC) for the cost of debt and an equity return component. Depreciation of utility plant is calculated using the straight-line method over the estimated service lives of the assets of twenty years. Depreciation is recorded using the group method of depreciation which is commonly used by pipelines, utilities and similar entities. When utility plant is retired or otherwise disposed of, the cost, less net proceeds, is normally charged to “Accumulated Provision for Depreciation, Amortization and Depletion” and no gain or loss on disposal is recognized in “Gain/Loss on Disposition of Utility Plant.”</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%">Included in utility plant are specified amounts of natural gas that must be maintained by Nautilus to operate its natural gas pipelines. The natural gas that must be maintained in order for the pipeline to properly operate is commonly referred to as Linepack. As is customary with most natural gas transportation entities, Nautilus owns the natural gas maintained as Linepack in its pipelines. The cost of natural gas that is owned by Nautilus and used for Linepack has been capitalized and is not depreciated.</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%">Regulatory guidance issued by the FERC requires Nautilus to expense certain costs associated with implementing the pipeline integrity management requirements of the United States Department of Transportation’s Office of Pipeline Safety. Under this guidance, costs to (1) prepare a plan to implement the program; (2) identify high consequence areas; (3) develop and maintain a record keeping system; and (4) inspect, test and report on the condition of affected pipeline segments to determine the need for repairs or replacements, are required to be expensed. Costs of modifying pipelines to permit in-line inspections, certain costs associated with developing or enhancing computer software and costs associated with remedial mitigation actions to correct an identified condition continue to be capitalized. Nautilus capitalizes certain costs such as sleeving or recoating existing pipelines, unless the expenditures are incurred as a single event and not part of a major program, in which case Nautilus expenses these costs as incurred.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Preliminary Project Costs</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">. Project development costs, including expenditures for preliminary surveys, plans, investigations, environmental studies, regulatory applications and other costs incurred for the purpose of determining the feasibility of capital expansion projects, are capitalized for rate-regulated enterprises when it is determined that recovery of such costs through regulated revenues of the completed project is probable. </span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Long-Lived Asset Impairment. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">Nautilus evaluates whether long-lived assets have been impaired when circumstances indicate the carrying value of those assets may not be recoverable. 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. Sources to determine fair value include, but are not limited to, recent third-party comparable sales, internally developed discounted cash flow analyses and analyses from outside advisors. Significant changes in market conditions resulting from events such as changes in natural gas available to our system, the condition of an asset, a change in our intent to utilize the asset or a significant change in contracted revenues or regulatory recoveries would generally require us to reassess the cash flows related to the long-lived assets. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Asset Retirement Obligations (AROs). </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">FERC requires the recording of liabilities equal to the fair value of AROs and corresponding additional asset costs. The obligations included are those for which there is a legal obligation as a result of existing or enacted law, statute or contract. Over time, the liability would be accreted to its present value, and the capitalized cost would be depreciated over the useful life of the related asset. Upon settlement of the liability, an entity would either settle the obligation for its recorded amount or recognize a gain or loss.</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%">Nautilus' assets are under the jurisdiction of the Department of Transportation and the Bureau of Ocean Energy Management (BOEM), and the Bureau of Safety and Environment Enforcement (BSEE). The BSEE requires the ultimate abandonment of offshore facilities when they are no longer in use or when suspension for future utilization cannot be justified. No AROs have been recorded based on insufficient information to reasonably determine the timing and /or method of settlement for estimating the fair value of the ARO.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Commitments and Contingencies. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">Liabilities for commitments and contingencies are recognized when, after fully analyzing available information, Nautilus determines it is either probable that an asset has been impaired, or that a liability has been incurred, and the amount of impairment or loss can be reasonably estimated. When a range of probable loss can be estimated, Nautilus recognizes the most likely amount, or if no amount is more likely than another, the minimum of the range of probable loss is accrued. Nautilus expenses legal costs associated with loss contingencies as such costs are incurred.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Environmental Expenditures. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">Nautilus expenses environmental expenditures related to conditions caused by past operations that do not generate current or future revenues. Environmental expenditures related to operations that generate current or future revenues are expensed or capitalized, as appropriate. Undiscounted liabilities are recorded when the necessity for environmental remediation becomes probable and the costs can be reasonably estimated, or when other potential environmental liabilities are reasonably estimable and probable.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Adoption of New Accounting Standards.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%"> The following new Accounting Standards Updates (ASUs) were adopted during 2021 and the effects of such adoptions, if any, are presented in the accompanying Financial Statements:</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:118%">Accounting for Contract Assets and Liabilities from Contracts with Customers in a Business Combination</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:118%">Effective November 1, 2021, we adopted Accounting Standards Update (ASU) 2021-08 on a retrospective basis beginning January 1, 2021.

The financial statements presented herein have been prepared in accordance with the accounting requirements of the FERC, as set forth in the applicable Uniform System of Accounts (USOA) and published accounting releases which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America (U.S. GAAP). Our accounting policies generally conform to FERC USOA. The most significant differences between U.S. GAAP and the financial statements presented herein are: (1) classification of certain accounts on the Comparative Balance Sheet, Statement of Income and the Statement of Cash Flows and (2) accounting for income taxes on a regulatory basis using the stand-alone method of income tax allocation.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Use of Estimates.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> The preparation of financial statements requires us to make estimates and assumptions that affect the amounts reported in the Financial Statements and Notes to Financial Statements. Although these estimates are based on our best available knowledge at the time, actual results could differ.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:118%">Fair Value Measurements. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:118%">We measure the fair value of financial assets and liabilities by maximizing the use of observable inputs and minimizing the use of unobservable inputs. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value of cash and cash equivalents, accounts receivable and accounts payable are not materially different from their carrying amounts because of the short-term nature of these instruments or because stated rates approximate market rates.</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:121%">Cost-Based Regulation. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:121%">We account for our regulated operations under the provisions of FERC USOA</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:121%">. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:121%">The economic effects of regulation can result in a regulated company recording assets for costs that have been or are expected to be approved for recovery from customers or recording liabilities for amounts that are expected to be returned to customers in the rate-setting process in a period different from the period in which the amounts would be recorded by an unregulated enterprise. Accordingly, we record assets and liabilities that result from the regulated ratemaking process that may not be recorded under U.S. GAAP for non-regulated entities. We continually assess whether regulatory assets are probable of future recovery by considering factors such as applicable regulatory changes and recent rate orders applicable to other regulated entities. Based on this assessment, we believe our existing regulatory assets are probable of recovery. These regulatory assets and liabilities are classified on the Comparative Balance Sheet as Deferred Debits and Deferred Credits.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Revenue Recognition.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> Revenues from the transportation of natural gas are recognized when the service is provided. 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. Differences between actual and estimated revenues are immaterial. We also have certain customer contracts with billed amounts that decline annually over the terms of the contract. Differences between the amounts billed and recognized are deferred on the Comparative Balance Sheet. See Note 2 for further discussion.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Accumulated Provision for Uncollectible Accounts - Credit.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;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%">Accounts receivable are measured at cost. Accumulated Provision for Uncollectible Accounts - Credit (account 144) is determined based on current expected credit losses. When we have determined that further collection efforts are unlikely to be successful, amounts are charged to this account and are applied against the impaired Customer Accounts Receivable (account 142).</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Allowance for Funds Used During Construction (AFUDC). </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">AFUDC, which represents the estimated debt and equity costs of capital funds necessary to finance the construction of certain new regulated facilities, consists of two components, an equity component and an interest expense component. The equity component is a non-cash item. After construction is completed, we are permitted to recover these costs through inclusion in the rate base and in the depreciation provision. </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%">AFUDC is capitalized as a component of Total Utility Plant cost, with offsetting credits to the Statements of Income through Other Income and Deductions for the equity component and Interest Charges for the interest expense component.

Income taxes have been historically recorded in accordance with the FERC Policy Statement on Income Tax Allowances issued in 1995 in Docket No. PL05-5, which permitted the accrual of income taxes on a pass-through entity. Income taxes are continuing to be recorded in this manner in light of the purchase by Spectra Energy Corp, a corporate subsidiary of Enbridge Inc., in December 2018, of all of the outstanding publicly-traded units of Spectra Energy Partners, LP (“SEP”), our immediate partner. M&amp;N LLC is now wholly owned by two U.S. corporations that are subject to U.S. income tax. Deferred income taxes are recognized for differences between the financial reporting and tax bases 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></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:115%">On March 15, 2018, in Docket No. PL17-1-000, the FERC changed its long-standing policy on the treatment of income tax included in the rates of pipelines and other entities subject to cost of service rate regulation within a Master Limited Partnership (MLP). In its order, the FERC revised its policy in Docket No. PL05-5, and stated that its policy was to no longer permit entities organized as an MLP to recover an income tax allowance in their cost of service rates on the basis that investor-level income tax costs are reflect in an MLP pipeline’s cost of service through the return on equity rate base.</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:115%">On July 18, 2018, the FERC issued an Order in Docket No. PL17-1-001, that: (1) dismissed all requests for rehearing of its March 15, 2018 revised policy statement on the treatment of income tax costs and explained that </span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:115%">its revised policy statement does not establish a binding rule, but is instead an expression of general policy that the Commission intends to follow in the future; and (2) provides guidance that because an MLP pipeline’s cost of service no longer includes income tax costs in the form of an income tax allowance pursuant to FERC’s Revised Policy Statement, then the MLP pipeline may remove Accumulated Deferred Income Tax (ADIT) balances from its Part 201 (18 C.F.R.

Since settlement of certain imbalances is in-kind, changes in their balances do not have an effect on our Statement of Cash Flows. Miscellaneous Current and Accrued Assets include $20.1 million and $5.2 million as of December 31, 2021 and 2020, respectively, and Miscellaneous Current and Accrued Liabilities include $18.7 million and $4.2 million as of December 31, 2021 and 2020, respectively, related to all gas imbalances.

We capitalize all construction-related direct labor and material costs, as well as indirect construction costs. Indirect costs include general engineering, taxes, and the cost of funds used during construction. The costs of renewals and betterments that extend the useful life or increase the expected output of property, plant and equipment are also capitalized. The costs of repairs, replacements and major maintenance projects, that do not extend the useful life or increase the expected output of property, plant and equipment, are expensed as incurred. Depreciation is generally computed over the asset’s estimated useful life using the straight-line method. The composite weighted-average depreciation rates were 2.15% and 2.21% for the years ended December 31, 2021 and December 31, 2020, respectively.

When we sell entire regulated operating units, or retire or sell non-regulated properties, the cost is removed from the property account and the related accumulated depreciation and amortization accounts are reduced. Any gain or loss is recorded in earnings, unless otherwise required by the FERC.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Preliminary Project Costs.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%"> Project development costs, including expenditures for preliminary surveys, plans, investigations, environmental studies, regulatory applications and other costs incurred for the purpose of determining the feasibility of capital expansion projects, are capitalized for rate-regulated enterprises when it is determined that recovery of such costs through regulated revenues of the completed project is probable. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Long-Lived Asset Impairment.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%"> We evaluate whether long-lived assets have been impaired when circumstances indicate the carrying value of those assets may not be recoverable. 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 for 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 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. Sources to determine fair value include, but are not limited to, recent third-party comparable sales, internally developed discounted cash flow analyses and analyses from outside advisors. Significant changes in market conditions resulting from events such as changes in natural gas available to our systems, the condition of an asset, a change in our intent to utilize the asset or a significant change in contracted revenues or regulatory recoveries would generally require us to re-assess the cash flows related to the long-lived assets. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:112%">Asset Retirement Obligations.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%"> We recognize asset retirement obligations (AROs) for legal commitments associated with the retirement of long-lived assets that result from the acquisition, method of settlement are conditional on a future event that may or may not be within our control. The fair value of a liability for an ARO is recognized in the period in which it is incurred if a reasonable estimate of fair value can be made and is added to the carrying amount of the associated asset. This additional carrying amount is depreciated over the estimated useful life of the asset. Substantially all our assets have an indeterminate life, and as such, the fair value of the retirement obligation is not reasonably estimable. There were no amounts recorded for AROs at December 31, 2021 and 2020.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Unamortized Debt Premium, Discount and Expense. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Premiums, discounts and expenses incurred with the issuance of outstanding long-term debt are amortized over the terms of the debt issues.

Overthrust may collect revenues subject to possible refunds and establish reserves pending final orders from regulatory agencies. Customer receivables at December 31, 2021 and 2020 included $5.7 million and $5.5 million, respectively, of accrued unbilled revenue based on estimated amounts of natural gas delivered but not yet billed to its customers.

Substantially all of Overthrust’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.

The 2017 Tax Reform Act included provisions that stipulate how plant-related, or “protected”, excess deferred taxes may be amortized. The FERC has also provided guidance on the amortization of non-plant-related, or “unprotected” excess of deferred taxes. Overthrust is using the average rate assumption method (“ARAM”) to calculate the amortization of its excess accumulated deferred income taxes associated with plant-related temporary differences. Under the ARAM, the excess accumulated deferred income taxes will reverse at the weighted average rate at which the deferred taxes were built over the remaining book life of the property to which those deferred taxes relate. These reversal periods range from one to 28 years. For non-plant-related excess or deficient accumulated deferred income taxes, the balances will reverse when the underlying book or tax item to which those deferred taxes relate has been realized or settled. All unprotected differences reversed in prior years.</span></div><div><span><br/></span></div><div style="text-align:justify"><span

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 Overthrust. Accordingly, the deferred income taxes were redetermined on the date of acquisition, December 31, 2021, resulting in an adjustment to equity of $67.4 million. The deferred income tax assets and liabilities are based on a preliminary purchase price. Overthrust intends adjust its accumulated deferred income balances to reflect the transaction once the purchase price is finalized.</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%">Overthrust files U.S. federal and state income tax returns in jurisdictions with varying statutes of limitations.

Prior to its change in parent, Overthrust 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 Overthrust 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
