Effective January 1, 2018, guidance under ASC 606 requires entities to include the fair value of the noncash consideration in the transaction price.

For FERC, costs related to debt reacquisition with refunding can be recognized immediately, amortized over the remaining life of the original debt, or amortized over the life of the new debt. Respondent has elected to amortize these costs over the remaining life of the original debt.

federal and state income tax purposes. As a result, Southwest Gas obtained a step-up in the bases of the assets acquired for income tax purposes, without succeeding to the holding period, accounting methods, or historical income tax liabilities associated with Respondent. Accordingly, all historical deferred income taxes were removed, and were redetermined on the date of acquisition, December 31, 2021, resulting in a net adjustment to equity of $244.6 million. The deferred income tax assets and liabilities are based on a preliminary purchase price. MountainWest Pipeline intends to adjust its accumulated deferred income balances to reflect the transaction once the purchase price is finalized.</span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:112%">MountainWest Pipeline files U.S. federal and state income tax returns in jurisdictions with varying statutes of limitations.

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

These legal proceedings and governmental examinations may involve demands for unspecified amounts of damages. The circumstances of any such legal proceedings and governmental examinations may change from time to time. Currently, management does not anticipate that any potential liability arising from such proceedings would have a material effect on the financial position, liquidity or results of operations of MountainWest Pipeline. As of December 31, 2021 and 2020, Respondent had no material legal proceedings or governmental examinations requiring the recognition of a liability. In March 2022, a complaint in U.S. district court was served on MountainWest Pipeline and a number of other defendants, alleging royalty payments due. While management disputes the allegations, the ultimate outcome is currently indeterminable and inestimable, but management does not believe that it would be material to Respondent’s financial position, liquidity, or results of operations overall. </span></div><div><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:107%">In April 2019, legislation was signed in Colorado that significantly amended the Oil and Gas Conservation Act, set a new mission of the Oil and Gas Conservation Commission and called for 12 future rulemakings.

MountainWest Pipeline is still evaluating whether potential impacts on results of operations, financial condition and/or cash flows related to this matter will be material.

Firm transportation and storage agreements primarily provide for a fixed reservation charge based on the pipeline or storage capacity reserved, and a commodity charge based on the volume of natural gas delivered/stored, each at rates specified in our FERC tariffs or as negotiated with our customers, with contract terms that are generally long-term in nature. Most of our long-term contracts contain an evergreen provision, which allows the contracts to be extended for periods primarily up to one year in length an indefinite number of times following the specified contract term and until terminated generally by either us or the customer. Interruptible transportation and storage agreements provide for a volumetric charge based on actual commodity transportation or storage utilized in the period in which those services are provided, and the contracts are generally limited to one-month periods or less. Our performance obligations include the following:</span></div><div style="margin-top:10pt;padding-left:45pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Firm transportation or storage under firm transportation and storage contracts - an integrated package of services typically constituting a single performance obligation, which includes standing ready to provide such services and receiving, transporting or storing (as applicable), and redelivering commodities;</span></div><div style="margin-top:10pt;padding-left:45pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Interruptible transportation and storage under interruptible transportation and storage contracts - an integrated package of services typically constituting a single performance obligation once scheduled, which includes receiving, transporting or storing (as applicable), and redelivering commodities.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In situations where, in our judgment, we consider the integrated package of services as a single performance obligation, which represents a majority of our contracts with customers, we do not consider there to be multiple performance obligations because the nature of the overall promise in the contract is to stand ready (with regard to firm transportation and storage contracts), receive, transport or store, and redeliver natural gas to the customer; therefore, revenue is recognized over time upon satisfaction of our daily stand ready performance obligation.</span></div><div style="margin-top:10pt;text-align:justify;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We recognize revenues for reservation charges over the performance obligation period, which is the contract term, regardless of the volume of natural gas that is transported or stored. Revenues for commodity charges from both firm and interruptible transportation services and storage services are recognized when natural gas is delivered at the agreed upon delivery point or when natural gas is injected or withdrawn from the storage facility because they specifically relate to our efforts to provide these distinct services. Generally, reservation charges and commodity charges are recognized as revenue in the same period they are invoiced to our customers. As a result of the ratemaking process, certain amounts collected by us may be subject to refunds upon the issuance of final orders by the FERC in pending rate proceedings.

Additionally, we transport gas on various pipeline systems which may deliver different quantities of gas on behalf of us than the quantities of gas received from us. These transactions result in gas transportation and exchange imbalance receivables and payables which are recovered or repaid in cash (see Deferred Cash Out below) or through the receipt or delivery of gas in the future and are recorded in the accompanying Balance Sheet. Settlement of imbalances requires agreement between the pipelines and shippers as to allocations of volumes to specific transportation contracts and timing of delivery of gas based on operational conditions. Our tariff includes a method whereby most transportation imbalances are settled on a monthly basis. Each month a portion of the imbalances are not identified to specific parties and remain unsettled. These are generally identified to specific parties and settled in subsequent periods. We believe that amounts that remain unidentified to specific parties and unsettled at year end are valid balances that will be settled with no material adverse effect upon our financial position, results of operations or cash flows. Management has implemented a policy of continuing to carry any unidentified transportation and exchange imbalances on the books for a three-year period. At the end of the three-year period a final assessment will be made of their continued validity. Absent a valid reason for maintaining the imbalance, any remaining balance will be recognized in income. Certain imbalances are being recovered or repaid in cash or through the receipt or delivery of gas upon agreement of the parties as to the allocation of the gas volumes, and as permitted by pipeline operating conditions.
