The cost of planning, designing, constructing and operating pipelines must incorporate compliance with these laws, regulations and safety standards. Failure to comply with these laws and regulations may trigger a variety of administrative, civil and potentially criminal enforcement measures, including citizen suits, which can include the assessment of monetary penalties, the imposition of remedial requirements and the issuance of injunctions or restrictions on operation or construction.

On February 28, 2020, we filed with the FERC a Stipulation and Offer of Settlement (the Settlement) which resulted in an overall reduction to Viking’s rates. The FERC approved the Settlement in July 2020. In 2020, our financial statements reflected a $1.0 million accrual for rate refunds in Account 496, Provision for Rate Refunds.

Through a services agreement (Services Agreement), ONEOK provides to us similar services that it provides to other affiliates and operates our assets according to our pipeline’s operating agreement. ONEOK and its affiliates provide a variety of services to us under the Services Agreement, including cash management and financial services, employee benefits provided through ONEOK’s benefit plans, legal and administrative services, insurance and office space leased in ONEOK’s headquarters building and other field locations. Where costs are specifically incurred on behalf of us, the costs are billed directly to us by ONEOK. In other situations, the costs may be allocated to us through a variety of methods, depending upon the nature of the expense and activities. For example, a service that applies equally to all employees is allocated based upon the number of employees; however, an expense benefiting us, but which has no direct basis for allocation, is allocated by the modified Distrigas method, a widely recognized method of allocating cost, which uses a combination of ratios that includes gross plant and investment, operating income and payroll expense. </span></div><div style="margin-top:2pt;padding-right:18pt"><span><br/></span></div><div style="margin-top:2pt;padding-right:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We hold a certificate of public convenience and necessity from the Federal Energy Regulatory Commission (FERC) that authorizes us to construct and operate our pipeline system, which includes performing routine construction/abandonment activities and providing transportation service for our customers.</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:120%">Our system serves approximately 40 firm transportation shippers.

The accounting requirements of the FERC are subject to review by the FERC staff.

The tariff specifies the general terms and conditions of transportation service on our natural gas pipeline system. Revenues are recognized as services are provided to our customers in an amount that reflects the consideration we expect to be entitled to receive in exchange for those services. Our payment terms vary by customer and contract type, including requiring payment before services are delivered to certain customers. However, the term between customer prepayments, completion of our performance obligations, invoicing and receipt of payment due is not significant.</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:120%">Firm service transportation contracts - </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We reserve a stated transportation capacity and transport natural gas for our customers.

Fixed capacity reservation fees are allocated and evenly recognized in revenue. Capacity reservation fees that vary based on a stated or implied economic index and correspond with the costs to provide our services are recognized in revenue based on a daily effective fee rate. If the capacity reservation fees vary solely as a contract feature, contract assets or liabilities are recorded for the difference between the amount recorded in revenue and the amount billed to the customer. Transportation fees are recognized in revenue as those services are provided and are dependent on the volume transported by our customer, which is at our customer’s discretion. We use the output method based on the passage of time to measure satisfaction of the performance obligation associated with our daily stand-ready services. Our firm service agreements extend for various terms with termination dates through October 2029.</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:120%">Interruptible transportation contracts - </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We agree to transport natural gas on our pipelines between the customer’s nominated receipt and delivery points if capacity is available after satisfying firm transportation service obligations. The transaction price is based on the transportation fees times the volumes transported. We use the output method based on delivery of product to the customer to measure satisfaction of the performance obligation. The total consideration for delivered volumes is recorded in revenue at the time of delivery, when the customer obtains control. We have interruptible transportation service agreements and other transportation service agreements with numerous shippers. Revenues from interruptible transportation contracts were $1.6 million and $0.5 million in 2021 and 2020, respectively.</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:120%">Park-and-loan service</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> - A service offered to customers where we agree to receive (park) or deliver (loan) natural gas at a nominated point for delivery to or receipt from the customer at the same point at a specified later date.

We assess creditworthiness of our counterparties on an ongoing basis and require security, including prepayments and other forms of collateral, when appropriate. Outstanding customer receivables are reviewed regularly for possible nonpayment indicators, and allowances for credit losses are recorded based upon management’s estimate of collectability, current conditions and supportable forecasts at each balance sheet date. We have not recorded allowances for credit losses as of 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%">Inventory -</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> Account 154 “Plant materials and operating supplies” are valued at average cost.

These imbalances can be settled through cash outs (purchases or sales at the current month index price) or in-kind (with natural gas at some time in the future), subject to the terms of our tariff agreement. We account for our fuel cost, which represents the difference between gas retained from our customers and the gas consumed in operations, through a tracking mechanism and record it as an imbalance. Our fuel costs are expected to be recovered or refunded in subsequent periods. We value these imbalances due to or from shippers and operators each month at the current market price. </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:120%">Imbalances due from others are reported on the balance sheet as miscellaneous current and accrued assets.

We capitalize interest costs during the construction or upgrade of qualifying assets. Capitalized interest is recorded as a reduction to interest expense. The equity portion of AFUDC represents the capitalization of the estimated average cost of equity used during the construction of major projects and is recorded in the cost of our properties and as a credit to the allowance for equity funds used during construction.</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:120%">Our properties are depreciated using the straight-line method over their estimated useful lives. Generally, we apply composite depreciation rates to functional groups of property having similar economic lives. We periodically conduct depreciation studies to assess the economic lives of our assets. These depreciation studies are completed as a part of our rate proceedings or tariff filings, and the changes in economic lives, if applicable, are implemented prospectively when the new rates are approved. Changes in the estimated economic lives of our property, plant and equipment could have a material effect on our financial position or results of operations.</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:120%">The composite depreciation rate, including negative salvage, for transmission plant ranged from 1.6% to 6.9% for the years ended December 31, 2021 and 2020.

An impairment is indicated if the carrying amount of a long-lived asset exceeds the sum of the undiscounted future cash flows expected to result from the use and eventual disposition of the asset. If an impairment is indicated, we record an impairment loss equal to the difference between the carrying value and the fair value of the long-lived asset. </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:120%">In 2021, there were no events or changes in circumstances to indicate that our assets’ carrying amounts may not be recoverable. Our natural gas transportation capacity contracted has not been significantly impacted in 2021 and 2020 by market conditions and the Coronavirus disease 2019 pandemic, as our end users rely on natural gas to support their business regardless of commodity price fluctuations. We continue to experience stable earnings with all of our transportation capacity fully contracted with firm commitments, and have not experienced any indicators that this will change in the future.

Certain examples of types of regulatory guidance include costs for fuel and losses, acquisition costs, contributions in aid of construction, charges for depreciation, and gains or losses on </span></div><div style="margin-bottom:6pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">disposition of assets. This allows us to stabilize rates over time rather than passing such costs on to the customer for immediate recovery.

We are not able to estimate reasonably the fair value of the asset retirement obligations for portions of our assets, primarily certain pipeline assets, because the settlement dates are indeterminable given our expected continued use of the assets with proper maintenance. We expect our pipeline assets, for which we are unable to estimate reasonably the fair value of the asset retirement obligation, will continue in operation as long as supply and demand for natural gas exists.

We accrue these contingencies when our assessments indicate that it is probable that a liability has been incurred or an asset will not be recovered and an amount can be estimated reasonably. We expense legal fees as incurred and base our legal liability estimates on currently available facts and our estimates of the ultimate outcome or resolution. Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of a remediation feasibility study. Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable.

(Enbridge)) and 50% by DTM NEXUS, LLC (a direct subsidiary of DT Midstream, Inc (DTM)). We were formed on September 9, 2015. We are engaged in natural gas transmission of natural gas received from Appalachian shale gas supplies to markets in the United States (US) Midwest, including Ohio, Michigan and Illinois, as well as Ontario, Canada. We are subject to the rules and regulations of the Federal Energy Regulatory Commission (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:118%">Basis of Presentation.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:118%"> 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, (2) accounting for income taxes on a regulatory basis using the stand-alone method of income tax allocation and (3) subsidiaries are reflected under the equity method accounting whereas GAAP requires that all controlled subsidiaries be consolidated.</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%">Use of Estimates.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:118%"> 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><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:118%">Cost-Based Regulation.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:118%"> We account for our regulated operations under the provisions of FERC 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, 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 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:118%">Revenue Recognition.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:118%"> Revenues from the transportation of natural gas are recognized when the service is provided.

These </span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:118%">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. 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:118%">Accumulated Provision for Uncollectible Accounts - Credit.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:118%"> 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:118%">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:118%"> 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:118%">AFUDC is capitalized as a component of Total Utility Plant cost, with offsetting credits to the Statement of Income through Other Income and Deductions for the equity component and Interest Charges for the interest expense component. The total amount of AFUDC included in the Statements of Income was insignificant in 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:112%">Income Taxes.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%"> 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 (SEP), our immediate partner. NEXUS 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 style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%"> </span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">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 reflected 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:118%">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 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.

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 Utility Plant is also capitalized. The costs of repairs, replacements and major maintenance projects that do not extend the useful life or increase the expected output of Utility Plant, 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 1.72% for and 1.68% for the years ended December 31, 2021 and December 31, 2020, respectively.

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:118%">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 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:118%">Asset Retirement Obligations. </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:118%">We recognize asset retirement obligations (AROs) for legal commitments associated with the retirement of long-lived assets that result from the acquisition, construction, development and/or normal use of the asset and conditional AROs in which the timing or 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. We have determined that substantially all of our assets have indeterminate lives, and as such, the fair values of those associated retirement obligations are not reasonably estimable.

The cost of property additions, replacements and improvements capitalized includes labor, material and overhead. Maintenance projects that do not increase the overall life of the related assets are expensed as incurred. In the ordinary course of business, the cost of property retired, plus removal costs less salvage, is charged to accumulated depreciation.

The overall rate of depreciation for the years ended December 31, 2021 and 2020 was approximately 2.74% and 2.75%, respectively. The Company estimates the pipelines have useful lives ranging from 20 years to 65 years and the compression structures and equipment have useful lives ranging from 30 to 50 years.

The Company uses the liability 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 the Company’s assets and liabilities and adjustments to the existing deferred tax balances for changes in tax rates. Where deferred tax liabilities or assets will be passed through to customers in regulated rates, the Company establishes a corresponding regulatory asset or liability for the increase or decrease in future revenues that will result when the temporary differences reverse.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:400;line-height:120%">Natural Gas Imbalances</span></div><div><span><br/></span></div><div><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 from a pipeline system or storage facility differs from the amount of natural gas scheduled.

Rate regulation provided by the FERC is designed to enable the Company to recover the costs of providing the regulated services plus an allowed return on invested capital. The application of regulatory accounting allows the Company to defer expenses and income on its balance sheets as regulatory assets and liabilities when it is probable that those expenses and income will be allowed in the rate setting process in a period different from the period in which they would have been reflected in the statements of operations for a non-regulated company. The deferred regulatory assets and liabilities are then recognized in the statements of operations in the period in which the same amounts are reflected in rates. The amounts deferred are to be recovered over the regulated period. The amounts deferred in the balance sheets relate primarily to the accounting for income taxes, AFUDC, transmission retainage tracker on the mainline system, transmission and storage retainage trackers on the AVC system and post-retirement benefit costs. The Company believes that it will continue to be subject to rate regulation that will provide for the recovery of deferred costs.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:400;line-height:120%">Revenue Recognition</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">Revenue is measured based on considerations specific in a contract with a customer.

Firm service is provided under firm contracts, which are contracts for transmission or storage services that generally obligate the customer to pay a fixed, monthly charge to reserve an agreed upon amount of pipeline or storage capacity regardless of the capacity used by the customer during each month. Volumetric-based fees can also be charged under firm contracts for each firm volume transported or stored, as well as for volumes transported or stored in excess of the firm contracted volume, if storage capacity exists. Interruptible service contracts include volumetric-based fees, which are charges for the volume of gas transported, stored or gathered and generally do not guarantee access to the pipeline or storage facility. Firm and interruptible contracts can be short- or long-term in duration. Firm and interruptible transmission and storage service contracts are billed at the end of each calendar month, with payment typically due within 10 days. Interruptible gathering contracts are billed on a one-month lag, with payment typically due within 21 days. Revenue related to gathering services provided but not yet billed is estimated each month. These estimates are generally based on contract data, preliminary throughput and allocation measurements.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:115%">Under a firm contract, the Company has a stand-ready obligation to provide the service over the life of the contract. The performance obligation for firm reservation fee revenue is satisfied over time as the pipeline capacity is made available to the customer. As such, the Company recognizes firm reservation fee revenue evenly over the contract period using a time-elapsed output method to measure progress. The performance obligation for volumetric-based fee revenue is generally satisfied upon the Company's monthly billing to the customer for volumes transported, stored or gathered during the month. The amount billed generally corresponds </span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:115%">directly to the value of the Company's performance to date as the customer obtains value as each volume is transported, stored or gathered.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">For all contracts, the Company allocates the transaction price to each performance obligation based on the judgment determined relative standalone selling price.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-style:italic;font-weight:400;line-height:120%">Contingencies</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:12pt;font-weight:400;line-height:120%">The Company is involved in various regulatory and legal proceedings that arise in the ordinary course of business.

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 pipelines business and are not within the scope of ASC Topic 606, “Revenues from Contracts with Customers” (ASC 606).

Most of our firm transportation and storage agreements 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 scheduled, 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 beyond the specified contract term and until terminated generally by either us or the customer, but in certain cases unilaterally by the customer, with advance notice of termination ranging from one to five years. 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.

Revenues for commodity charges from both firm and interruptible transportation services and storage services are recognized based on volumes of natural gas scheduled for delivery at the agreed upon delivery point or based on volumes of natural gas scheduled for injection 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.

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:18pt"><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 identified polychlorinated biphenyl (PCB) contamination in air compressor systems, soils, and related properties at certain compressor station sites. Similarly, we identified hydrocarbon impacts at these facilities due to the former use of earthen pits, lubricating oil leaks or spills, and excess pipe coating released to the environment. In addition, heavy metals have been identified at these sites due to the former use of mercury containing meters and paint and welding rods containing lead, cadmium, and arsenic. The PCBs were remediated pursuant to a Consent Decree with the U.S. Environmental Protection Agency (EPA) in the late 1980s, and we conducted a voluntary clean-up of the hydrocarbon and mercury impacts in the early 1990s. In 2005, the Washington Department of Ecology required us to re-evaluate our previous clean-ups in Washington. During 2006 to 2015, 129 meter stations were evaluated, of which 82 required remediation. As of December 31, 2021, 2 meter stations are still being remediated.
