The reduction in the corporate tax rate was effective on January&#160;1, 2018, reducing the Company's income tax expense for 2018. The Company continues to review the components of the TCJA and the impact on the Company's consolidated financial statements and related disclosures for 2018 and thereafter. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">While the Company was able to make reasonable estimates of the impact of the reduction in corporate tax rate on the Company's net deferred tax liabilities during the fourth quarter of 2017, such estimates may be affected by other analyses related to the TCJA, including, but not limited to, the state tax effect of adjustments to federal temporary differences and the calculation of deemed repatriation of deferred foreign income. The final transition impacts of the TCJA may differ from amounts disclosed, possibly materially, due to, among other things, interpretations, legislative action to address questions, changes in accounting standards for income taxes or related interpretations, or updates or changes to estimates the Company has utilized to calculate the transition impacts. The SEC has issued rules that would allow for a measurement period of up to one year after the enactment date of the TCJA to finalize the recording of the related tax impacts, of which there were no such material adjustments during the nine months ended September 30, 2018. The Company currently anticipates finalizing and recording any resulting adjustments by December&#160;31, 2018, which will be included in income from continuing operations. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Due to the enactment of the TCJA, the regulated jurisdictions in which the Company's regulated businesses provide service have requested the Company furnish plans for the effect of the reduced corporate tax rate, which may impact the Company's rates to customers.

The Company will continue to make changes to reserve balances as new information becomes available.

Revenue from Contracts with Customers </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In May&#160;2014, the FASB issued guidance on accounting for revenue from contracts with customers. The guidance provides for a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry specific guidance.

With this decision, the guidance was effective for the Company on January&#160;1, 2018. Entities had the option of using either a full retrospective or modified retrospective approach to adopting the guidance. Under the modified retrospective approach, an entity recognizes the cumulative effect of initially applying the guidance with an adjustment to the opening balance of retained earnings in the period of adoption. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company adopted the guidance on January&#160;1, 2018, using the modified retrospective approach. The Company elected the practical expedient to not disclose the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied (or partially unsatisfied) as of the end of the reporting period, along with an explanation of when such revenue would be expected to be recognized. This practical expedient was used since the performance obligations are part of contracts with an original duration of one year or less. The Company also elected the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company otherwise would have recognized is one year or less. Upon completion of the Company's evaluation of contracts and methods of revenue recognition under the previous accounting guidance, the Company did not identify any material cumulative effect adjustments to be made to retained earnings. In addition, the Company has expanded revenue disclosures, both quantitatively and qualitatively, related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, as discussed in Note&#160;</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">8</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. The Company reviewed its revenue streams to evaluate the impact of this guidance and did not identify a significant change in the timing of revenue recognition, results of operations, financial position or cash flows. The Company reviewed its internal controls related to revenue recognition and disclosures and concluded that the guidance impacted certain business processes and controls. As such, the Company developed modifications to its internal controls for certain topics under the guidance as they apply to the Company and such modifications were not deemed to be significant. Results for reporting periods beginning after December&#160;31, 2017, are presented under the new guidance, while prior period amounts are not adjusted and continue to be reported in accordance with historic accounting for revenue recognition.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Under the modified retrospective approach, the guidance was applied only to contracts that were not completed as of January&#160;1, 2018.

The guidance is intended to standardize the presentation and classification of certain transactions, including cash payments for debt prepayment or extinguishment, proceeds from insurance claim settlements and distributions from equity method investments. In addition, the guidance clarifies how to classify transactions that have characteristics of more than one class of cash flows.

The guidance is effective for the Company on January&#160;1, 2019, including interim periods, with early adoption permitted. The guidance can be applied using one of two methods. One method is to record the reclassification of the stranded income taxes at the beginning of the period of adoption. The other method is to apply the guidance retrospectively to each period in which the income tax effects of the TCJA are recognized in accumulated other comprehensive income (loss). The Company early adopted the guidance on January&#160;1, 2018, and elected to reclassify the stranded income taxes at the beginning of the period.

The guidance requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet for operating and financing leases. The guidance remains largely the same for lessors, although some changes were made to better align lessor accounting with the new lessee accounting and to align with the revenue recognition standard. The guidance also requires additional disclosures, both quantitative and qualitative, related to operating and finance leases for the lessee and sales-type, direct financing and operating leases for the lessor. This guidance will be effective for the Company on January&#160;1, 2019, with early adoption permitted. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In July&#160;2018, the FASB issued ASU 2018-11 - </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;">Leases: Targeted Improvements,</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> an accounting standard update to ASU 2016-02. This ASU provides an entity the option to adopt the guidance using one of two modified retrospective approaches. An entity can adopt the guidance using the modified retrospective transition approach beginning in the earliest year presented in the financial statements. This method of adoption would require the restatement of prior periods reported and the presentation of lease disclosures under the new guidance for all periods reported. The additional transition method of adoption introduced by ASU 2018-11, allows entities the option to apply the guidance on the date of adoption by recognizing a cumulative effect adjustment to retained earnings during the period of adoption and does not require prior comparative periods to be restated. The Company is planning to adopt the standard on January&#160;1, 2019, utilizing the practical expedient that allows the Company to not reassess whether an expired or existing contract contains a lease, the classification of leases or initial direct costs, as well as the additional transition method of adoption applied on the date of adoption. The Company also plans to adopt a short-term leasing policy as the lessee where leases with a term of 12 months or less will not be included on the Consolidated Balance Sheet.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company formed a lease implementation team and is currently in the contract review and assessment phase to identify and evaluate contracts containing leases. Additionally, the team is implementing new and revising existing software to meet the reporting and disclosure requirements of the standard. The Company also has started to assess the impact the standard will have on its processes and internal controls and is identifying new and updating current processes. During the assessment phase, the Company is using various analytic methodologies to ensure the completeness of the lease inventory. The Company expects that most of the current operating leases will be subject to the guidance and recognized as operating lease liabilities and right-of-use assets on the Consolidated Balance Sheets upon adoption. During the fourth quarter of 2018, the Company will engage internal auditors to review and assess the completeness of the lease inventory and the effectiveness of the revised and new internal controls. The Company continues to evaluate the impact the new guidance will have on lease contracts where the Company is the lessor and, at this time, does not anticipate a significant impact. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In January&#160;2018, the FASB issued a practical expedient for land easements under the new lease guidance. The practical expedient permits an entity to elect the option to not evaluate land easements under the new guidance if they existed or expired before the adoption of the new lease guidance and were not previously accounted for as leases under the previous lease guidance. Once an entity adopts the new guidance, the entity should apply the new guidance on a prospective basis to all new or modified land easements.

This guidance requires entities to perform a quantitative impairment test, previously Step&#160;1, to identify both the existence of impairment and the amount of impairment loss by comparing the fair value of a reporting unit to its carrying amount. Entities will continue to have the option of performing a qualitative assessment to determine if the quantitative impairment test is necessary. The guidance also requires additional disclosures if an entity has one or more reporting units with zero or negative carrying amounts of net assets. The guidance will be effective for the Company on January&#160;1, 2020, and must be applied on a prospective basis with early adoption permitted.

The guidance modifies, among other things, the disclosures required for Level 3 fair value measurements, including the range and weighted average of significant unobservable inputs. The guidance removes, among other things, the disclosure requirement to disclose transfers between Levels 1 and 2. The guidance will be effective for the Company on January&#160;1, 2020, including interim periods, with early adoption permitted.

The guidance removes disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The guidance adds, among other things, the requirement to include an explanation for significant gains and losses related to changes in benefit obligations for the period. The guidance removes, among other things, the disclosure requirement to disclose the amount of net periodic benefit costs to be amortized over the next fiscal year from accumulated other comprehensive income (loss) and the effects a one percentage point change in assumed health care cost trend rates will have on certain benefit components.

The guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract similar to the costs incurred to develop or obtain internal-use software and such capitalized costs to be expensed over the term of the hosting arrangement. Costs incurred during the preliminary and postimplementation stages should continue to be expensed as activities are performed. The capitalized costs are required to be presented on the balance sheet in the same line the prepayment for the fees associated with the hosting arrangement would be presented. In addition, the expense related to the capitalized implementation costs should be presented in the same line on the income statement as the fees associated with the hosting element of the arrangements.

performance obligation is satisfied by transferring control over a product or service to a customer. Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company is considered an agent for certain taxes collected from customers. As such, the Company presents revenues net of these taxes at the time of sale to be remitted to governmental authorities, including sales and use taxes.</ix:nonNumeric></span></div><ix:continuation id="TextSelection-61BDCB8C00CE6745FED9CF6DFB7F9D82-1" continuedAt="TextSelection-61BDCB8C00CE6745FED9CF6DFB7F9D82-2"><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The electric and natural gas distribution segments generate revenue from the sales of electric and natural gas products and services, which includes retail and transportation services. These segments establish a customer's retail or transportation service account based on the customer's application/contract for service, which indicates approval of a contract for service. The contract identifies an obligation to provide service in exchange for delivering or standing ready to deliver the identified commodity; and the customer is obligated to pay for the service as provided in the applicable tariff. The product sales are based on a fixed rate that includes a base and per-unit rate, which are included in approved tariffs as determined by state or federal regulatory agencies. The quantity of the commodity consumed or transported determines the total per-unit revenue. The service provided, along with the product consumed or transported, are a single performance obligation because both are required in combination to successfully transfer the contracted product or service to the customer. Revenues are recognized over time as customers receive and consume the products and services.

For contracts governed by the Company&#8217;s utility tariffs, amounts are billed monthly with the amount due between 15 and 22 days of receipt of the invoice depending on the applicable state&#8217;s tariff. For other contracts not governed by tariff, payment terms are net thirty days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The pipeline and midstream segment generates revenue from providing natural gas transportation, gathering and underground storage services, as well as other energy-related services to both third parties and internal customers, largely the natural gas distribution segment. The pipeline and midstream segment establishes a contract with a customer based upon the customer&#8217;s request for firm or interruptible natural gas transportation, storage or gathering service(s). The contract identifies an obligation for the segment to provide the requested service(s) in exchange for consideration from the customer over a specified term. Depending on the type of service(s) requested and contracted, the service provided may include transporting, gathering or storing an identified quantity of natural gas and/or standing ready to deliver or store an identified quantity of natural gas. Natural gas transportation, gathering and storage revenues are based on fixed rates, which may include reservation fees and/or per-unit commodity rates. The services provided by the segment are generally treated as single performance obligations satisfied over time simultaneous to when the service is provided and revenue is recognized. Rates for the segment&#8217;s regulated services are based on its FERC approved tariff or customer negotiated rates on special projects, and rates for its non-regulated services are negotiated with its customers and set forth in the contract. For contracts governed by the company&#8217;s tariff, amounts are billed on or before the ninth business day of the following month and the amount is due within twelve days of receipt of the invoice. For gathering contracts not governed by the tariff, amounts are due within twenty days of invoice receipt. For other contracts not governed by the tariff, payment terms are net thirty days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The construction materials and contracting segment generates revenue from contracting services and construction materials sales. This segment focuses on the vertical integration of its contracting services with its construction materials to support the aggregate based product lines. This segment provides contracting services to a customer when a contract has been signed by both the customer and a representative of the segment obligating a service to be provided in exchange for the consideration identified in the contract. The nature of the services this segment provides generally includes integrating a set of services and related construction materials into a single project to create a distinct bundle of goods and services, which the Company evaluates to determine whether a separate performance obligation exists. The transaction price is the original contract price plus any subsequent change orders and variable consideration. Examples of variable consideration that exist in this segment's contracts include liquidated damages; performance bonuses or incentives and penalties; claims; unapproved/unpriced change orders; and index pricing. The variable amounts usually arise upon achievement of certain performance metrics or change in project scope. The Company estimates the amount of revenue to be recognized on variable consideration using estimation methods that best predict the most likely amount of consideration the Company expects to be entitled to or expects to incur. The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Changes in circumstances could impact management's estimates made in determining the value of variable consideration recorded. The Company updates its estimate of the transaction price each reporting period and the effect of variable consideration on the transaction price is recognized as an adjustment to revenue on a cumulative catch-up basis. Revenue is recognized over time using the input method based on the measurement of progress on a project. The input method is the preferred method of measuring revenue because the costs incurred have been determined to represent the best indication of the overall progress toward the transfer of such goods or services promised to a customer. This segment also sells construction materials to third parties and internal customers. The contract for material sales is the use of a sales order or an invoice, which includes the pricing and payment terms. All material contracts contain a single performance obligation for the delivery of a single distinct product or a distinct separately identifiable bundle of products and services. Revenue is recognized at a point in time when the performance obligation has been satisfied with the delivery of the products or services. The warranties associated with the sales are those consistent with a standard warranty that the product meets certain specifications for quality or those required by law. For most contracts, amounts billed to customers are due within thirty days of receipt. There are no material obligations for returns, refunds or other similar obligations.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The construction services segment generates revenue from specialty contracting services which also includes the sale of construction equipment and other supplies. This segment provides specialty contracting services to a customer when a contract has been signed by both the customer and a representative of the segment obligating a service to be provided in exchange for the consideration identified in the contract. The nature of the services this segment provides generally includes multiple promised goods and services in a single project to create a distinct bundle of goods and services, which the Company evaluates to determine whether a separate performance obligation exists.

The timing of invoicing to customers does not necessarily correlate with the timing of revenues being recognized under the cost&#8208;to&#8208;cost method of accounting. Contracts from contracting services are billed as work progresses in accordance with agreed upon contractual terms. Generally, billing to the customer occurs contemporaneous to revenue recognition. A variance in timing of the billings may result in a contract asset or a contract liability. A contract asset occurs when revenues are recognized under the cost-to-cost measure of progress, which exceeds amounts billed on uncompleted contracts. Such amounts will be billed as standard contract terms allow, usually based on various measures of performance or achievement. A contract liability occurs when there are billings in excess of revenues recognized under the cost-to-cost measure of progress on uncompleted contracts. Contract liabilities decrease as revenue is recognized from the satisfaction of the related performance obligation. <ix:nonNumeric contextRef="FD2018Q3YTD"

Fair values for some of the assets were determined based on Level 3 inputs including estimated future cash flows, discount rates, growth rates, sales projections, retention rates and terminal values, all of which require significant management judgment and are susceptible to change. The purchase price allocation is based upon preliminary information and is subject to change if additional information about the facts and circumstances that existed at the acquisition date becomes available. The final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill. However, any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations. The discount rate used in calculating the fair value of the common stock issued was determined by a Black-Scholes-Merton model. The model used Level 2 inputs including risk-free interest rate, volatility range and dividend yield. The results of the acquired businesses have been included in the Company's construction materials and contracting segment and consolidated financial statements beginning on the acquisition dates. Pro forma financial amounts reflecting the effects of the above acquisitions are not presented, as such acquisitions were not material to the Company's financial position or results of operations.</ix:continuation></span></div><div><a id="s14A12534B30D5853AF3C67F0EC62B5B3"></a></div><div style="line-height:120%;padding-top:14px;font-size:11pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;text-decoration:underline;">Note </span><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;text-decoration:underline;">10</span><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;text-decoration:underline;"> - </span><ix:nonNumeric contextRef="FD2018Q3YTD" name="us-gaap:DisposalGroupsIncludingDiscontinuedOperationsDisclosureTextBlock" id="TextSelection-15526034CEB5AF6EF571CF6DFB8005F4-0-wk-Fact-C8245DF28C22CC500406CF6DFAB9314C" continuedAt="TextSelection-15526034CEB5AF6EF571CF6DFB8005F4-1" escape="true"><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;text-decoration:underline;">Discontinued operations</span><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;text-decoration:underline;"> </span></ix:nonNumeric></div><ix:continuation id="TextSelection-15526034CEB5AF6EF571CF6DFB8005F4-1" continuedAt="TextSelection-15526034CEB5AF6EF571CF6DFB8005F4-2"><div style="line-height:120%;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The assets and liabilities of the Company's discontinued operations have been classified as held for sale and the results of operations are shown in income (loss) from discontinued operations, other than certain general and administrative costs and interest expense which do not meet the criteria for income (loss) from discontinued operations.

is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The fair value ASC establishes a hierarchy for grouping assets and liabilities, based on the significance of inputs. The estimated fair values of the Company's assets and liabilities measured on a recurring basis are determined using the market approach. The Company's Level&#160;2 money market funds are valued at the net asset value of shares held at the end of the quarter, based on published market quotations on active markets, or using other known sources including pricing from outside sources. The estimated fair value of the Company's Level&#160;2 mortgage-backed securities and U.S. Treasury securities are based on comparable market transactions, other observable inputs or other sources, including pricing from outside sources. The estimated fair value of the Company's Level&#160;2 insurance contract is based on contractual cash surrender values that are determined primarily by investments in managed separate accounts of the insurer. These amounts approximate fair value. The managed separate accounts are valued based on other observable inputs or corroborated market data.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Though the Company believes the methods used to estimate fair value are consistent with those used by other market participants, the use of other methods or assumptions could result in a different estimate of fair value.

Accruals are based on the best information available, but in certain situations management is unable to estimate an amount or range of a reasonably possible loss including, but not limited to when: (1) the damages are unsubstantiated or indeterminate, (2) the proceedings are in the early stages, (3) numerous parties are involved, or (4) the matter involves novel or unsettled legal theories.</ix:nonNumeric> </span></div></ix:continuation><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:8pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:8pt;">31</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div></div><div><br/></div><ix:continuation id="TextSelection-1F578C64E4A003B06C7CCF6DFB83ED9C-2" continuedAt="TextSelection-1F578C64E4A003B06C7CCF6DFB83ED9C-3"><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company accrued liabilities of </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$<ix:nonFraction id="d4111705e576-wk-Fact-EFBF8CE93F0A7AFDEB93CF6DFB1FAB26" name="us-gaap:LossContingencyAccrualAtCarryingValue" contextRef="FI2018Q3" unitRef="usd" decimals="-5" scale="6" format="ixt:numdotdecimal">30.4</ix:nonFraction>&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$<ix:nonFraction id="d4111705e580-wk-Fact-4CE175910F840865B72FCF6DFB1E12B0" name="us-gaap:LossContingencyAccrualAtCarryingValue" contextRef="FI2017Q3" unitRef="usd" decimals="-5" scale="6" format="ixt:numdotdecimal">34.3</ix:nonFraction>&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> and </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$<ix:nonFraction id="d4111705e584-wk-Fact-A5DD11D235A2FCA69E55CF6DFB224873" name="us-gaap:LossContingencyAccrualAtCarryingValue" contextRef="FI2017Q4" unitRef="usd" decimals="-5" scale="6" format="ixt:numdotdecimal">35.4</ix:nonFraction>&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, which have not been discounted, including liabilities held for sale, for contingencies, including litigation, production taxes, royalty claims and environmental matters at </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">September&#160;30, 2018</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> and </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">2017</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, and </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">December&#160;31, 2017</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, respectively.

The Coyote Station owners are also providing a guarantee of the value of the assets of Coyote Creek as they would be required to buy the assets at book value should they terminate the contract prior to the end of the contract term and are providing a guarantee of the value of the equity of Coyote Creek in that they are required to buy the entity at the end of the contract term at equity value. Although the Company has determined that Coyote Creek is a VIE, the Company has concluded that it is not the primary beneficiary of Coyote Creek because the authority to direct the activities of the entity is shared by the four unrelated owners of the Coyote Station, with no primary beneficiary existing. As a result, Coyote Creek is not required to be consolidated in the Company's financial statements.</span></div></ix:continuation><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><ix:continuation id="TextSelection-1F578C64E4A003B06C7CCF6DFB83ED9C-5" continuedAt="TextSelection-1F578C64E4A003B06C7CCF6DFB83ED9C-6"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">At </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">September&#160;30, 2018</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, the Company's exposure to loss as a result of the Company's involvement with the VIE, based on the Company's ownership percentage, was </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$<ix:nonFraction id="d4111705e872-wk-Fact-6A4A6590E91F9109F8BFCF6DFB1B475C" name="us-gaap:VariableInterestEntityEntityMaximumLossExposureAmount" contextRef="FI2018Q3_us-gaap_VariableInterestEntitiesByClassificationOfEntityAxis_mdu_FuelContractMember" unitRef="usd" decimals="-5" scale="6" format="ixt:numdotdecimal">39.2</ix:nonFraction>&#160;million</span></span></ix:continuation><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><ix:continuation id="TextSelection-1F578C64E4A003B06C7CCF6DFB83ED9C-6">.</ix:continuation></span></div><div><a id="sc52ed5e350b54036882af883a9107dfd"></a></div><div style="line-height:120%;padding-top:14px;font-size:11pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;text-decoration:underline;">Note </span><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;text-decoration:underline;">18</span><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;text-decoration:underline;"> - <ix:nonNumeric contextRef="FD2018Q3YTD" name="us-gaap:SubsequentEventsTextBlock" id="TextSelection-E13E5C36B65ADC63BDEFA7C0110DD370-0-wk-Fact-382E8C46F17EE6075393A7C22086F555" continuedAt="TextSelection-E13E5C36B65ADC63BDEFA7C0110DD370-1" escape="true">Subsequent Events</ix:nonNumeric></span></div><ix:continuation id="TextSelection-E13E5C36B65ADC63BDEFA7C0110DD370-1" continuedAt="TextSelection-E13E5C36B65ADC63BDEFA7C0110DD370-2"><div style="line-height:120%;padding-bottom:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">On October&#160;4, 2018, the Company acquired Sweetman Construction Company, a provider of aggregates, asphalt and ready-mixed concrete in South Dakota, which will be included in the Company's construction materials and contracting segment.

Its regulated energy delivery platform and its construction materials and services platform are each comprised of different operating segments. Some of these segments experience seasonality related to the industries in which they operate. The two-platform approach helps balance this seasonality and the risk associated with each type of industry. Through its regulated energy delivery platform, the Company provides electric and natural gas services to customers, generates, transmits and distributes electricity, and provides natural gas transportation, storage and gathering services. These businesses are regulated by state public service commissions and/or the FERC. The construction materials and services platform provides construction services to a variety of industries, including commercial, industrial and governmental, and provides construction materials through aggregate mining and marketing of related products, such as ready-mixed concrete and asphalt.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company is organized into five reportable business segments. These business segments include: electric, natural gas distribution, pipeline and midstream, construction materials and contracting, and construction services. The Company's business segments are determined based on the Company's method of internal reporting, which generally segregates the strategic business units due to differences in products, services and regulation. The internal reporting of these segments is defined based on the reporting and review process used by the Company's chief executive officer.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company's strategy is to apply its expertise in the regulated energy delivery and construction materials and services businesses to increase market share, increase profitability and enhance shareholder value through organic growth opportunities and strategic acquisitions. The Company is focused on a disciplined approach to the acquisition of well-managed companies and properties. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company has capabilities to fund its growth and operations through various sources, including internally generated funds, commercial paper facilities, revolving credit facilities, term loans and the issuance from time to time of debt and equity securities.

Some of the more material changes from the TCJA impacting the Company included lower corporate tax rates, repealing the domestic production deduction, disallowance of immediate expensing for regulated utility property and modifying or repealing many other business deductions and credits. The Company continues to review the components of the TCJA and evaluate the impact on the Company for 2018 and thereafter.

At the construction materials and contracting business, higher asphalt product volumes and margins and higher construction revenues and margins contributed to the increased earnings. The Company's earnings were negatively impacted from a net decrease in revenues due to changes in estimates of variable consideration related to certain construction contracts at the construction services business, as well as increased operation and maintenance expense and reserves against revenues in certain jurisdictions for anticipated refunds to customers for lower income taxes as a result of the TCJA at the natural gas distribution business.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">Nine Months Ended</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"> </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">September&#160;30, 2018</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">, Compared to </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">Nine Months Ended</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"> </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">September&#160;30, 2017</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"> </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company recognized consolidated earnings of </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">$193.5 million</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> for the </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">nine</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> months ended </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">September&#160;30, 2018</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, compared to </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">$165.1 million</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> for the same period in 2017.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Positively impacting the Company's earnings were decreased income taxes across all business segments as a result of lower corporate tax rates due to the TCJA and a tax benefit from the reversal of a regulatory liability at the pipeline and midstream business, as previously discussed. The earnings at the construction materials and contracting business increased due to higher construction revenues and margins resulting from favorable job performance and strong demand in certain regions. Higher nonregulated project revenues and transportation revenues at the pipeline and midstream business also contributed to the increase in earnings. The construction services business had increased earnings as a result of higher equipment sales and rentals partially offset by a net decrease in revenues due to changes in estimates of variable consideration related to certain construction contracts.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">A discussion of key financial data from the Company's business segments follows.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:8pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:8pt;">35</span></div></div><hr style="page-break-after:always"></hr><div><a id="sAAF803CDF9AB5E64A295262695C6D007"></a></div><div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div></div><div><br/></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:12pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:12pt;">Business Segment Financial and Operating Data</span><span style="font-family:Trade Gothic,sans-serif;font-size:12pt;"> </span></div><div style="line-height:120%;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Following are key financial and operating data for each of the Company's business segments.

Both segments strive to be a top performing utility company measured by integrity, safety, employee satisfaction, customer service and shareholder return, while continuing to focus on providing safe, reliable and competitively priced energy and related services to customers. The Company continues to monitor opportunities for these segments to retain, grow and expand their customer base through extensions of existing operations, including building and upgrading electric generation and transmission and natural gas systems, and through selected acquisitions of companies and properties at prices that will provide stable cash flows and an opportunity to earn a competitive return on investment. The continued efforts to create operational improvements and efficiencies across both segments promotes the Company's business integration strategy. The primary factors that impact the results of these segments are the ability to earn authorized rates of return, the cost of natural gas, cost of electric fuel and purchased power, weather, competitive factors in the energy industry, population growth and economic conditions in the segments' service areas. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The electric and natural gas distribution segments are subject to extensive regulation in the jurisdictions where they conduct operations with respect to costs, timely recovery of investments and permitted returns on investment, as well as certain operational, system integrity and environmental regulations. To assist in the reduction of regulatory lag with the increase in investments, tracking mechanisms have been implemented in certain jurisdictions. Legislative and regulatory initiatives to increase renewable energy resources and reduce GHG emissions could impact the price and demand for electricity and natural gas and result in the retirement of certain electric generating facilities before they are fully depreciated. Although the current administration has slowed environmental regulations, the segments continue to invest in facility upgrades to be in compliance with the existing and future regulations.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Tariff increases on steel and aluminum materials could negatively affect the segments' construction projects and maintenance work. The Company continues to monitor the impact tariff increases will have on raw material costs. The natural gas distribution segment is also facing increased lead times on delivery of certain raw materials used in pipeline projects. In addition to the effect of tariffs, long lead times are attributable to increased demand for steel products from pipeline companies as they respond to the United States Department of Transportation Pipeline System Safety and Integrity Plan. The Company continues to monitor the material lead times and is working with manufacturers to proactively order such materials to help mitigate the extended lead times.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The ability to grow through acquisitions is subject to significant competition and acquisition premiums. In addition, the ability of the segments to grow their service territory and customer base is affected by the economic environment of the markets served and competition from other energy providers and fuels. The construction of any new electric generating facilities, transmission lines and other service facilities is subject to increasing cost and lead time, extensive permitting procedures, and federal and state legislative and regulatory initiatives, which will necessitate increases in electric energy prices. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Revenues are impacted by both customer growth and usage, the latter of which is primarily impacted by weather. Very cold winters increase demand for natural gas and to a lesser extent, electricity, while warmer than normal summers increase demand for electricity, especially among residential and commercial customers. Average consumption among natural gas customers has tended to decline as more efficient appliances and furnaces are installed, and as the Company has implemented conservation programs. Decoupling mechanisms in certain jurisdictions have been implemented to largely mitigate the effect that would otherwise be caused by variations in volumes sold to these customers due to weather and changing consumption patterns on the Company's distribution margins.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:8pt;"><span

Customer growth is expected to grow by 1&#160;percent to 2&#160;percent per year. This customer growth, along with system upgrades and replacements needed to supply safe and reliable service, will require investments in new electric generation and transmission and natural gas systems. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In November 2017, the NDPSC approved the advance determination of prudence for the purchase of the Thunder Spirit Wind farm expansion in southwest North Dakota. Construction of the Thunder Spirit Wind farm expansion began in May 2018. In February 2018, the Company signed a purchase agreement to obtain ownership of the expansion. In August 2018, the FERC granted approval for the Company to purchase the Thunder Spirit Wind farm expansion and on October 31, 2018, the Company finalized the purchase and placed into service the Thunder Spirit Wind farm expansion. With the addition of the expansion, the total Thunder Spirit Wind farm generation capacity will be approximately 155 MW and will increase the Company's electric generation portfolio to approximately 27&#160;percent renewables based on nameplate ratings. The Company's integrated resource plans filed in North Dakota and Montana in 2017 include additional generation projects in the 2025 timeframe.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In June 2016, the Company, along with a partner, began construction on the BSSE project. The estimated capital investment for this project has been narrowed to a range of $130&#160;million to $140&#160;million. All necessary easements have been secured and construction is well underway. The project is expected to be completed in the first quarter of 2019.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company continues to be focused on the regulatory recovery of its investments. The Company files for rate adjustments to seek recovery of operating costs and capital investments, as well as reasonable returns as allowed by regulators. The Company's most recent cases by jurisdiction are discussed in Note </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">16</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">With the enactment of the TCJA, the state regulators in jurisdictions where the segments operate have requested companies submit plans for the estimated impact of the TCJA. The segments determined the use of the deferral method of accounting for the revaluation of its regulated deferred tax assets and liabilities was appropriate. As such, the Company recorded a regulatory liability for the excess deferred income taxes that related to the effect of the change in tax rates on its regulated deferred tax assets and liabilities in the fourth quarter of 2017. For the nine months ended September 30, 2018, the Company reserved an additional regulatory liability of approximately $16.0&#160;million, which is an offset to the Company's revenues, as previously discussed. The additional reserves were calculated by completing a revenue requirement calculation in each state where the Company thought it was probable that the refund of tax savings would be returned to the Company's customers. The Company continues to work with the state regulators on plans for the impacts of the TCJA, as discussed in Note&#160;</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">16</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. The Company anticipates the TCJA will negatively impact the segments' cash flows due to not being able to immediately expense utility property for tax purposes, as well as lower deferred taxes.</span></div><div style="line-height:120%;padding-left:4px;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company currently does not have any labor contracts in negotiations at the electric and natural gas distribution segments.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:8pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:8pt;">40</span></div></div><hr style="page-break-after:always"></hr><div><a id="sCFACA1EFDF7B5AD982B37118311925AA"></a></div><div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div></div><div><br/></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:11pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;">Pipeline and Midstream</span><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;"> </span></div><div style="line-height:120%;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">Strategy and challenges</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">&#160;The pipeline and midstream segment provides natural gas transportation, gathering and underground storage services, as discussed in Note </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">14</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. The segment focuses on utilizing its extensive expertise in the design, construction and operation of energy infrastructure and related services to increase market share and profitability through optimization of existing operations, organic growth and investments in energy-related assets within or in close proximity to its current operating areas. The segment focuses on the continual safety and reliability of its systems, which entails building and maintaining safe natural gas pipelines and facilities. The segment continues to evaluate growth opportunities including the expansion of existing storage, gathering and transmission facilities; incremental pipeline projects, which expand pipeline capacity; and expansion of energy-related services leveraging on its core competencies.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The segment is exposed to energy price volatility which is impacted by the fluctuations in pricing, production and basis differentials of the energy market's commodities. Legislative and regulatory initiatives to increase pipeline safety regulations and reduce methane emissions could also impact the price and demand for natural gas.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Tariff increases on steel and aluminum materials could negatively affect the segment's construction projects and maintenance work. The Company continues to monitor the impact tariff increases will have on raw material costs. The segment experiences extended lead times on raw materials that are critical to the segment's construction and maintenance work. Long lead times on materials could delay maintenance work and project construction potentially causing lost revenues and/or increased costs. The Company continues to proactively monitor and plan for the material lead times, as well as work with manufacturers and suppliers to help mitigate the extended lead times.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The pipeline and midstream segment is subject to extensive regulation including certain operational, system integrity and environmental regulations, as well as various permit terms and operational compliance conditions. The segment is charged with the ongoing process of reviewing existing permits and easements, as well as securing new permits and easements as necessary to meet current demand and future growth opportunities. Exposure to pipeline opposition groups could also cause negative impacts on the segment with increased costs and potential delays to project completion. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The segment focuses on the recruitment and retention of a skilled workforce to remain competitive and provide services to its customers. The industry in which it operates relies on a skilled workforce to construct energy infrastructure and operate existing infrastructure in a safe manner. A shortage of skilled personnel can create a competitive labor market which could increase costs incurred by the segment. Competition from other pipeline and midstream companies can also have a negative impact on the segment.</span></div><div><br/></div><div style="text-align:center;"><div

The following describes recent growth projects.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Construction on the Company's Valley Expansion project, a 38-mile pipeline that will deliver natural gas supply to eastern North Dakota and far western Minnesota, began in May 2018. The project, which is designed to transport 40 MMcf of natural gas per day, is under the jurisdiction of the FERC. Construction is on schedule with an in-service date in November 2018. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In September 2018, the Company completed construction and placed into service Line Section 27 Expansion project in the Bakken area of northwestern North Dakota. The project includes approximately 13 miles of new pipeline and associated facilities. The project increases capacity by over 200&#160;MMcf per day and brings total capacity of Line Section 27 to over 600&#160;MMcf per day. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Earlier this year, the Company announced two additional natural gas pipeline growth projects, the Demicks Lake project and Line Section 22 Expansion project. The Company has signed long-term commitment contracts supporting both projects. The Demicks Lake project, which includes approximately 14 miles of 20-inch pipe and will increase capacity by 175 MMcf per day, is located in McKenzie County, North Dakota. Construction is expected to begin in 2019, with an in-service date in the fall of 2019. The Line Section 22 Expansion project in the Billings, Montana, area is also scheduled for construction in 2019, with an expected in-service date in late 2019. The project will increase capacity by 22.5&#160;MMcf per day to serve incremental demand in Billings, Montana. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In 2017, the Company completed and placed into service the Charbonneau and Line Section 25 expansion projects, which include a new compression station, as well as other compressor additions and enhancements at existing stations. Partly due to the completion of these two expansion projects and the Line Section 27 project, the Company continues to transport increasing volumes of natural gas through its system. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The impact of the TCJA on the pipeline and midstream segment remains uncertain. As such, the regulated pipeline is using the deferral method of accounting for the revaluation of its regulated deferred tax assets and liabilities associated with non-negotiated rate contracts. No reserves have been established as a result of the TCJA enactment. The Company continues to monitor the FERC activity regarding TCJA, as discussed in Note </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">16</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">.</span></div><div style="line-height:120%;padding-left:4px;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company currently does not have any labor contracts in negotiations at the pipeline and midstream segment. </span></div><div><a id="s1AB1455BA8F5520E869F98BE0B5D6F33"></a></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:11pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;">Construction Materials and Contracting</span></div><div style="line-height:120%;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">Strategy and challenges </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The construction materials and contracting segment provides an integrated set of construction services, as discussed in Note </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">14</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. The segment focuses on high-growth strategic markets located near major transportation corridors and desirable mid-sized metropolitan areas; strengthening the long-term, strategic aggregate reserve position through available purchase and/or lease opportunities; enhancing profitability through cost containment, margin discipline and vertical integration of the segment's operations; development and recruitment of talented employees; and continued growth through organic and acquisition opportunities. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">A key element of the Company's long-term strategy for this business is to further expand its market presence in the higher-margin materials business (rock, sand, gravel, liquid asphalt, asphalt concrete, ready-mixed concrete and related products), complementing and expanding on the segment's expertise. The Company's acquisitions thus far in 2018 support this strategy.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">As one of the country's largest sand and gravel producers, the segment will continue to strategically manage its nearly 1.0 billion tons of aggregate reserves in all its markets, as well as take further advantage of being vertically integrated. The segment's vertical integration allows the segment to manage operations from aggregate mining to final lay-down of concrete and asphalt, with control of and access to permitted aggregate reserves being significant. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The construction materials and contracting segment faces challenges that are not under the direct control of the business. The segment operates in geographically diverse and highly competitive markets. Competition can put negative pressure on the segment's operating margins. The segment is also subject to volatility in the cost of raw materials such as diesel fuel, gasoline, liquid asphalt, cement and steel. In 2018, the segment has experienced higher diesel fuel and asphalt oil costs as compared to 2017. Such volatility can have a negative impact on the segment's margins. Other variables that can impact the segment's margins include adverse weather conditions, the timing of project starts or completion and declines or delays in new and existing projects due to the cyclical nature of the construction industry and federal infrastructure spending.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:8pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:8pt;">43</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div></div><div><br/></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The segment also faces challenges in the recruitment and retention of employees. Trends in the labor market include an aging workforce and availability issues. The segment continues to face increasing pressure to reduce costs and increase the use of temporary employment because of the seasonality of the work performed in certain regions. </span></div><div

The aggregate products are sold internally and externally for use in other products such as ready-mixed concrete, asphaltic concrete and public and private construction markets. The contracting services and construction materials are sold primarily to construction contractors in connection with street, highway and other public infrastructure projects, as well as private commercial and residential development projects. The public infrastructure projects have traditionally been more stable markets as public funding is more secure during periods of economic decline. The public funding is, however, dependent on state and federal funding such as appropriations to the Federal Highway Administration. Spending on private development is highly dependent on both local and national economic cycles, providing additional sales during times of strong economic cycles.</span></div><div style="line-height:120%;padding-left:4px;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company remains optimistic about overall economic growth and infrastructure spending. The IBIS World Industry Report issued in May 2018 for sand and gravel mining in the United States projects a 1.8&#160;percent annual growth rate over the next five years. The report also states the demand for clay and refractory materials is projected to continue deteriorating in several downstream manufacturing industries, but this decline will be offset by stronger demand from the housing market and buoyant demand from the highway and bridge construction market. This stronger demand in the housing markets along with continued demand from the highway and bridge construction markets should provide a stable demand for construction materials and contracting products and services in the near future.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In April 2018, the Company acquired Teevin &amp; Fischer Quarry, LLC, a crushed rock and gravel supplier in northwestern Oregon. In June 2018, the Company acquired Tri-City Paving, Inc., a general contractor and aggregate, asphalt and ready-mixed concrete supplier headquartered in Little Falls, Minnesota. In July 2018, the Company acquired Molalla Redi-Mix and Rock Products, Inc., which produces ready-mixed concrete in Molalla, Oregon. In October, 2018, the Company acquired Sweetman Construction Company, a premier provider of aggregates, asphalt and ready-mixed concrete in Sioux Falls, South Dakota. These acquisitions are expected to be accretive to the segment's earnings for 2018, as well as into 2019. The Company continues to evaluate additional acquisition opportunities. For more information on these acquisitions, see Notes&#160;</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">9</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> and 18.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The construction materials and contracting backlog at September 30, 2018, was $590.0 million, up from $519.7&#160;million at September&#160;30, 2017. The increase in backlog was primarily attributable to increased state agency work. </span></div><div style="line-height:120%;padding-left:4px;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The impact of the TCJA on the economy as a whole continues to be unclear at this time. As such, the impact to the construction materials and contracting industry is also uncertain. Under the TCJA, the domestic production deduction is no longer available. The domestic production deduction was originally introduced to incentivize domestic production activities and was a deduction of up to 9&#160;percent on qualified production activity income for which this segment's activities qualified. The Company expects the lower federal corporate tax rate will more than offset the loss of the domestic production deduction for this segment.</span></div><div style="line-height:120%;padding-left:4px;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company currently does not have any labor contracts in negotiations at the construction materials and contracting segment.</span></div><div><a id="s61B36EC175B35D2EB5BA7743A182B13D"></a></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:11pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;">Construction Services</span><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;"> </span></div><div style="line-height:120%;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">Strategy and challenges</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> The construction services segment provides inside and outside specialty contracting, as discussed in Note&#160;</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">14</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. The construction services segment focuses on providing a superior return on investment by building new and strengthening existing customer relationships; ensuring quality service; safely executing projects; effectively controlling costs; collecting on receivables; retaining, developing and recruiting talented employees; growing through organic and acquisition opportunities; and focusing efforts on projects that will permit higher margins while properly managing risk.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The construction services segment faces challenges in the highly competitive markets in which it operates. Competitive pricing environments, project delays, changes in management's estimates of variable consideration and the effects of restrictive regulatory requirements have negatively impacted revenues and margins in the past and could affect revenues and margins in the future. Additionally, margins may be negatively impacted on a quarterly basis due to adverse weather conditions, as well as timing of project starts or completions, declines or delays in new projects due to the cyclical nature of the construction industry and other </span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:8pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:8pt;">45</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div></div><div><br/></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">factors.

These trends include an aging workforce and labor availability issues, increasing pressure to reduce costs and improve reliability, and increasing duration and complexity of customer capital programs. Due to these and other factors, the Company believes customer demand for labor resources will continue to increase, possibly surpassing the supply of industry resources.</span></div><div

For the remainder of 2018 and into 2019, the Company continues to believe several projects will be available for bid, including bidding activity in small and medium-sized projects. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company continues to expect bidding activity to remain strong in both outside and inside specialty construction companies for the remainder of 2018 and into 2019. Although bidding remains highly competitive in all areas, the Company expects the segment's skilled workforce will continue to provide a benefit in securing and executing profitable projects. The construction services segment had backlog at September&#160;30, 2018, of $896.3&#160;million, up from $675.8&#160;million at September 30, 2017. The increase in backlog was primarily attributable to an increase in inside specialty construction projects based on customer demand. Additionally, the Company continues to evaluate potential acquisition opportunities that would be accretive to the Company and grow the Company's backlog.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The impact of the TCJA on the economy as a whole continues to remain unclear at this time. As such, the impact to the construction services industry is also uncertain. While it is unclear what impact the TCJA may have on the construction services industry, the Company is optimistic about overall economic growth and infrastructure spending and believes that improving industry activity will continue in both market segments and the drivers for investment will remain intact. As the Company continues to experience growth in its operations, the impacts of the lower corporate tax rate offsets the increase in taxes on operating income. The Company believes that regulatory reform, state renewable portfolio standards, the aging of the electric grid, and the general improvement of the economy will positively impact the level of spending by its customers.

The increase in cash provided by financing activities was largely due to increased debt issuance from an increase in commercial paper balances used for acquisitions, ongoing capital expenditures and working capital needs at the construction materials and contracting business; the issuance of an additional $40&#160;million under the private shelf agreement for capital projects at the pipeline and midstream business; and the issuance of a $100&#160;million term loan for capital projects at the electric and natural gas distribution businesses. This increase in issuance of long-term debt was partially offset by the higher debt repayment on a line of credit at the natural gas distribution business; higher debt repayment on debt that matured during third quarter 2018 at the electric and natural gas distribution businesses; and the strong collection of accounts receivable resulting in lower commercial paper balances at the construction services business.</span></div><div><a id="s78426ED81CA456A8A483B8E7F1C919D5"></a></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:11pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;">Defined benefit pension plans</span></div><div style="line-height:120%;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">There were no material changes to the Company's qualified noncontributory defined benefit pension plans from those reported in the </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">2017</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> Annual Report.

Commercial paper borrowings under this agreement are classified as long-term debt as they are intended to be refinanced on a long-term basis through continued commercial paper borrowings. The Company's objective is to maintain acceptable credit ratings in order to access the capital markets through the issuance of commercial paper. Historically, downgrades in the Company's credit ratings have not limited, nor are currently expected to limit, the Company's ability to access the capital markets. If the Company were to experience a downgrade of its credit ratings in the future, it may need to borrow under its credit agreement and may experience an increase in overall interest rates with respect to its cost of borrowings.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">On June 8, 2018, the Company entered into an amended and restated revolving credit agreement which extended the maturity date to June 8, 2023.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">On September 17, 2018, the Company entered into a $100.0 million term loan agreement with a variable interest rate and a maturity date of October 17, 2019.

The recognition of revenue requires the Company to make estimates and assumptions that affect the reported amounts of revenue. The accuracy of revenues reported on the Consolidated Financial Statements depends on, among other things, management's estimates of total costs to complete projects because the Company uses the cost-to-cost measure of progress on construction contracts for revenue recognition.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">To determine the proper revenue recognition method for contracts, the Company evaluates whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. This evaluation requires significant judgment and the decision to combine a group of contracts or separate the combined or single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. For most contracts, the customer contracts with the Company to provide a significant service of integrating a complex set of tasks and components into a single project. Hence, the Company's contracts are generally accounted for as one performance obligation.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company recognizes construction contract revenue over time using the cost-to-cost measure of progress for contracts because it best depicts the transfer of assets to the customer which occurs as the Company incurs costs on the contract. Under the cost-to-cost measure of progress, the costs incurred are compared with total estimated costs of a performance obligation. Revenues are recorded proportionately to the costs incurred. This method depends largely on the ability to make reasonably dependable estimates related to the extent of progress toward completion of the contract, contract revenues and contract costs. Inasmuch as contract prices are generally set before the work is performed, the estimates pertaining to every project could contain significant unknown risks such as volatile labor, material and fuel costs, weather delays, adverse project site conditions, unforeseen actions by regulatory agencies, performance by subcontractors, job management and relations with project owners. Changes in estimates could have a material effect on the Company's results of operations, financial position and cash flows.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Several factors are evaluated in determining the bid price for contract work. These include, but are not limited to, the complexities of the job, past history performing similar types of work, seasonal weather patterns, competition and market conditions, job site conditions, work force safety, reputation of the project owner, availability of labor, materials and fuel, project location and project completion dates. As a project commences, estimates are continually monitored and revised as information becomes available and actual costs and conditions surrounding the job become known. If a loss is anticipated on a contract, the loss is immediately recognized.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Contracts are often modified to account for changes in contract specifications and requirements. The Company considers contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Generally, contract modifications are for goods or services that are not distinct from the existing contract due to the significant </span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:8pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:8pt;">51</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div></div><div><br/></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">integration of services provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and the measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue on a cumulative catch-up basis.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company's construction contracts generally contain variable consideration including liquidated damages, performance bonuses or incentives, claims, unapproved/unpriced change orders and penalties or index pricing. The variable amounts usually arise upon achievement of certain performance metrics or change in project scope. The Company estimates the amount of revenue to be recognized on variable consideration using estimation methods that best predict the most likely amount of consideration the Company expects to be entitled to or expects to incur. The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Changes in circumstances could impact management's estimates made in determining the value of variable consideration recorded. The Company updates its estimate of the transaction price each reporting period and the effect of variable consideration on the transaction price is recognized as an adjustment to revenue on a cumulative catch-up basis.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company believes its estimates surrounding the cost-to-cost method are reasonable based on the information that is known when the estimates are made. The Company has contract administration, accounting and management control systems in place that allow its estimates to be updated and monitored on a regular basis. Because of the many factors that are evaluated in determining bid prices, it is inherent that the Company's estimates have changed in the past and will continually change in the future as new information becomes available for each job. There have been no material changes in contract estimates in 2018.</span></div><div style="line-height:120%;padding-top:14px;font-size:11pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:11pt;font-weight:bold;">Purchase accounting</span></div><div style="line-height:120%;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company accounts for acquisitions under the purchase method of accounting and, accordingly, the acquired assets and liabilities assumed are recorded at their respective fair values. The excess of the purchase price over the fair value of the assets acquired and liabilities assumed is recorded as goodwill. Acquired assets and liabilities assumed by the Company are subject to various estimates. The recorded values of assets and liabilities are based on third-party estimates and valuations when available. The remaining values are based on management's judgments and estimates, and accordingly, the Company's financial position or result of operations may be affected by changes in estimates and judgments.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The fair value of owned recoverable aggregate reserve deposits is determined using qualified internal personnel, as a well as external experts including geologists. Reserve estimates are calculated based on the best available data. This data is collected from drill holes and other subsurface investigations, as well as investigations of surface features such as mine high walls and other exposures of the aggregate reserves. Mine plans, production history and geologic data also are utilized to estimate reserve quantities. Value is assigned to the aggregate reserves based on a review of market royalty rates, comparable depletion rates, expected cash flows and the number of years of recoverable aggregate reserves at owned aggregate sites.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The fair value of property, plant and equipment is based on a valuation performed either by qualified internal personnel and/or external appraisers. Fair values assigned to plant and equipment are based on several factors including the age and conditions of the equipment, maintenance records of the equipment and auction values for equipment with similar characteristics at the time of purchase. The Intangible assets are valued using a discounted cash flows methodology. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">While the allocation of the purchase price of an acquisition is subject to a considerable degree of judgment and uncertainty, the Company does not expect the estimates to vary significantly once an acquisition has been completed. </span></div><div><a id="s4af94a0ad2214c45ba0d5a5ad1da92ae"></a></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:12pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:12pt;">Non-GAAP Financial Measures</span></div><div style="line-height:120%;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The following discussion includes financial information prepared in accordance with GAAP, as well as another financial measure, adjusted gross margin, that is considered a non-GAAP financial measure as it relates to the Company's electric and natural gas distribution segments. The presentation of adjusted gross margin is intended to be a useful supplemental financial measure for investors&#8217; understanding of the segments' operating performance. This non-GAAP financial measure should not be considered as an alternative to, or more meaningful than, GAAP financial measures such as operating income (loss) or earnings (loss). The Company's non-GAAP financial measure, adjusted gross margin, is not standardized; therefore, it may not be possible to compare this financial measure with other companies&#8217; gross margin measures having the same or similar names.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In addition to operating revenues and operating expenses, management also uses the non-GAAP financial measure of adjusted gross margin when evaluating the results of operations for the electric and natural gas distribution segments. Adjusted gross margin for the electric and natural gas distribution segments is calculated by adding back adjustments to operating income (loss). These add back adjustments include: operation and maintenance expense; depreciation, depletion and amortization expense; and certain taxes, other than income.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Adjusted gross margin includes operating revenues less cost of electric fuel and purchased power, purchased natural gas sold and certain taxes, other than income. These taxes, other than income included as a reduction to adjusted gross margin relate to revenue taxes. These segments pass on to their customers the increases and decreases in the wholesale cost of power purchases, natural gas and other fuel supply costs in accordance with regulatory requirements. As such, the segments' revenues are directly impacted by the fluctuations in such commodities. Revenue taxes, which are passed back to customers, fluctuate with revenues </span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:8pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:8pt;">52</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div></div><div><br/></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">as they are calculated as a percentage of revenues. Period over period, the segments' operating income (loss) is generally not impacted by the increase or decrease in revenues since the change is directly related to the increase or decrease in wholesale cost of power purchases, natural gas or other fuel supply costs, nor is it impacted by revenue taxes since it is a direct result of revenues. The Company's management believes the adjusted gross margin is a useful supplemental financial measure as these items are included in both operating revenues and operating expenses. The Company's management also believes that adjusted gross margin and the remaining operating expenses that calculate operating income (loss) are useful in assessing the Company's utility performance as management has the ability to influence control over the remaining operating expenses.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span

Interim financial statements do not include all disclosures provided in annual financial statements and, accordingly, these financial statements should be read in conjunction with those appearing in the &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;2017&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; Annual Report. The information is unaudited but includes all adjustments that are, in the opinion of management, necessary for a fair presentation of the accompanying consolidated interim financial statements and are of a normal recurring nature. Depreciation, depletion and amortization expense is reported separately on the Consolidated Statements of Income and therefore is excluded from the other line items within operating expenses. Management has also evaluated the impact of events occurring after &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;September&#160;30, 2018&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, up to the date of issuance of these consolidated interim financial statements.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On December 22, 2017, President Trump signed into law the TCJA which includes lower corporate tax rates, repealing the domestic production deduction, disallowance of immediate expensing for regulated utility property and modifying or repealing many other business deductions and credits. The reduction in the corporate tax rate was effective on January&#160;1, 2018, reducing the Company's income tax expense for 2018. The Company continues to review the components of the TCJA and the impact on the Company's consolidated financial statements and related disclosures for 2018 and thereafter. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;While the Company was able to make reasonable estimates of the impact of the reduction in corporate tax rate on the Company's net deferred tax liabilities during the fourth quarter of 2017, such estimates may be affected by other analyses related to the TCJA, including, but not limited to, the state tax effect of adjustments to federal temporary differences and the calculation of deemed repatriation of deferred foreign income. The final transition impacts of the TCJA may differ from amounts disclosed, possibly materially, due to, among other things, interpretations, legislative action to address questions, changes in accounting standards for income taxes or related interpretations, or updates or changes to estimates the Company has utilized to calculate the transition impacts. The SEC has issued rules that would allow for a measurement period of up to one year after the enactment date of the TCJA to finalize the recording of the related tax impacts, of which there were no such material adjustments during the nine months ended September 30, 2018. The Company currently anticipates finalizing and recording any resulting adjustments by December&#160;31, 2018, which will be included in income from continuing operations. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;Due to the enactment of the TCJA, the regulated jurisdictions in which the Company's regulated businesses provide service have requested the Company furnish plans for the effect of the reduced corporate tax rate, which may impact the Company's rates to customers. Therefore, the Company has reserved for such impacts as an offset to revenue in certain jurisdictions. The Company will continue to make changes to reserve balances as new information becomes available. For more information on the details and statuses of the open requests, see Note&#160;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;16&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;Effective January&#160;1, 2018, the Company adopted the requirements of the revenue from contracts with customers guidance following the modified retrospective method, as discussed in Notes &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;6&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;8&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;. As such, results for reporting periods beginning January&#160;1, 2018, are presented under the new guidance, while prior period amounts are not adjusted and continue to be reported in accordance with the historic accounting for revenue recognition. Based on the Company's analysis, the Company did not identify a significant change in the timing of revenue recognition under the new guidance as compared to the historic accounting for revenue recognition.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;Certain prior year amounts have been reclassified to conform to the current year presentation in the consolidated financial statements related to the retrospective adoption of the FASB guidance to improve the presentation of net periodic pension and net periodic postretirement benefit costs, which was effective on January 1, 2018. The components of net periodic pension and postretirement costs, other than service costs, were reclassified from operating expenses to other income on the Consolidated Statements of Income, as discussed in Note&#160;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;6&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;.&lt;/span&gt;&lt;/div&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The assets and liabilities for the Company's discontinued operations have been classified as held for sale and the results of operations are shown in income (loss) from discontinued operations, other than certain general and administrative costs and interest expense which do not meet the criteria for income (loss) from discontinued operations. At the time the assets were classified as held for sale, depreciation, depletion and amortization expense was no longer recorded. Unless otherwise indicated, the amounts presented in the accompanying notes to the consolidated financial statements relate to the Company's continuing operations.

A reconciliation of the weighted average common shares outstanding used in the basic and diluted earnings per share calculations was as follows:&lt;/span&gt;&lt;/div&gt;&lt;div

The guidance provides for a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry specific guidance. In August&#160;2015, the FASB issued guidance deferring the effective date of the revenue guidance and allowing entities to &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;early adopt. With this decision, the guidance was effective for the Company on January&#160;1, 2018. Entities had the option of using either a full retrospective or modified retrospective approach to adopting the guidance. Under the modified retrospective approach, an entity recognizes the cumulative effect of initially applying the guidance with an adjustment to the opening balance of retained earnings in the period of adoption. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The Company adopted the guidance on January&#160;1, 2018, using the modified retrospective approach. The Company elected the practical expedient to not disclose the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied (or partially unsatisfied) as of the end of the reporting period, along with an explanation of when such revenue would be expected to be recognized. This practical expedient was used since the performance obligations are part of contracts with an original duration of one year or less. The Company also elected the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company otherwise would have recognized is one year or less. Upon completion of the Company's evaluation of contracts and methods of revenue recognition under the previous accounting guidance, the Company did not identify any material cumulative effect adjustments to be made to retained earnings. In addition, the Company has expanded revenue disclosures, both quantitatively and qualitatively, related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, as discussed in Note&#160;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;8&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;. The Company reviewed its revenue streams to evaluate the impact of this guidance and did not identify a significant change in the timing of revenue recognition, results of operations, financial position or cash flows. The Company reviewed its internal controls related to revenue recognition and disclosures and concluded that the guidance impacted certain business processes and controls. As such, the Company developed modifications to its internal controls for certain topics under the guidance as they apply to the Company and such modifications were not deemed to be significant. Results for reporting periods beginning after December&#160;31, 2017, are presented under the new guidance, while prior period amounts are not adjusted and continue to be reported in accordance with historic accounting for revenue recognition.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;Under the modified retrospective approach, the guidance was applied only to contracts that were not completed as of January&#160;1, 2018. Therefore, the Company recognized the cumulative effect of initially applying the guidance with an adjustment to the opening balance of retained earnings at January&#160;1, 2018. For the nine months ended September&#160;30, &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;2018&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, there were &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;no&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; material impacts to the financial statements as a result of applying the guidance. The cumulative effect of the changes made to the Consolidated Balance Sheet were as follows:&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:10pt;"&gt;&lt;div

The guidance is intended to standardize the presentation and classification of certain transactions, including cash payments for debt prepayment or extinguishment, proceeds from insurance claim settlements and distributions from equity method investments. In addition, the guidance clarifies how to classify transactions that have characteristics of more than one class of cash flows. The Company adopted the guidance on January&#160;1, 2018, on a prospective basis. The guidance did not have a material effect on the Company's statement of cash flows.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2017-01 - Clarifying the Definition of a Business &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In January&#160;2017, the FASB issued guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The guidance provides a screen to determine when an integrated set of assets and activities is not a business. The guidance also affects other aspects of accounting, such as determining reporting units for goodwill testing and whether an entity has acquired or sold a business. The Company adopted the guidance on January&#160;1, 2018, on a prospective basis. The guidance did not have a material effect on the Company's results of operations, financial position, cash flows or disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2017-07 - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In March&#160;2017, the FASB issued guidance to improve the presentation of net periodic pension and net periodic postretirement benefit costs. The guidance required the service cost component to be presented in the income statement in the same line item or items as other compensation costs arising from services performed during the period. Other components of net periodic benefit cost shall be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. The guidance also only allows the service cost component to be capitalized.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The Company adopted the guidance on January&#160;1, 2018, on a retrospective basis. The guidance required the reclassification of all components of net periodic benefit costs, except for the service cost component, from operating expenses to other income on the Consolidated Statements of Income with no impact to earnings. As a result of the retrospective application of this change in accounting guidance, the Company reclassified &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$1.5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$4.5&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; from operation and maintenance expense to other income on the Consolidated Statements of Income for the &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;three and nine&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; months ended September&#160;30, 2017, respectively. The Company also reclassified unrealized gains on investments used to satisfy obligations under the defined benefit plans of &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$2.6&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$7.9&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; for the &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;three and nine&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; months ended September&#160;30, 2017, respectively, which were included in operation and maintenance expense, to other income on the Consolidated Statements of Income. The guidance did not have a material effect on the Company's results of operations, cash flows or disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2018-02 - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In February&#160;2018, the FASB issued guidance that allows an entity to reclassify the stranded tax effects resulting from the newly enacted federal corporate income tax rate from accumulated other comprehensive income (loss) to retained earnings. The guidance is effective for the Company on January&#160;1, 2019, including interim periods, with early adoption permitted. The guidance can be applied using one of two methods. One method is to record the reclassification of the stranded income taxes at the beginning of the period of adoption. The other method is to apply the guidance retrospectively to each period in which the income tax effects of the TCJA are recognized in accumulated other comprehensive income (loss). The Company early adopted the guidance on January&#160;1, 2018, and elected to reclassify the stranded income taxes at the beginning of the period. During the first quarter of 2018, the Company reclassified &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$7.9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; of stranded tax expense from accumulated other comprehensive loss to retained earnings. The guidance did not have a material effect on the Company's results of operations, cash flows or disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:10pt;font-weight:bold;"&gt;Recently issued accounting standards not yet adopted&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2016-02 - Leases &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In February&#160;2016, the FASB issued guidance regarding leases. The guidance requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet for operating and financing leases. The guidance remains largely the same for lessors, although some changes were made to better align lessor accounting with the new lessee accounting and to align with the revenue recognition standard. The guidance also requires additional disclosures, both quantitative and qualitative, related to operating and finance leases for the lessee and sales-type, direct financing and operating leases for the lessor. This guidance will be effective for the Company on January&#160;1, 2019, with early adoption permitted. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In July&#160;2018, the FASB issued ASU 2018-11 - &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;"&gt;Leases: Targeted Improvements,&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; an accounting standard update to ASU 2016-02. This ASU provides an entity the option to adopt the guidance using one of two modified retrospective approaches. An entity can adopt the guidance using the modified retrospective transition approach beginning in the earliest year presented in the financial statements. This method of adoption would require the restatement of prior periods reported and the presentation of lease disclosures under the new guidance for all periods reported. The additional transition method of adoption introduced by ASU 2018-11, allows entities the option to apply the guidance on the date of adoption by recognizing a cumulative effect adjustment to retained earnings during the period of adoption and does not require prior comparative periods to be restated. The Company is planning to adopt the standard on January&#160;1, 2019, utilizing the practical expedient that allows the Company to not reassess whether an expired or existing contract contains a lease, the classification of leases or initial direct costs, as well as the additional transition method of adoption applied on the date of adoption. The Company also plans to adopt a short-term leasing policy as the lessee where leases with a term of 12 months or less will not be included on the Consolidated Balance Sheet.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The Company formed a lease implementation team and is currently in the contract review and assessment phase to identify and evaluate contracts containing leases. Additionally, the team is implementing new and revising existing software to meet the reporting and disclosure requirements of the standard. The Company also has started to assess the impact the standard will have on its processes and internal controls and is identifying new and updating current processes. During the assessment phase, the Company is using various analytic methodologies to ensure the completeness of the lease inventory. The Company expects that most of the current operating leases will be subject to the guidance and recognized as operating lease liabilities and right-of-use assets on the Consolidated Balance Sheets upon adoption. During the fourth quarter of 2018, the Company will engage internal auditors to review and assess the completeness of the lease inventory and the effectiveness of the revised and new internal controls. The Company continues to evaluate the impact the new guidance will have on lease contracts where the Company is the lessor and, at this time, does not anticipate a significant impact. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In January&#160;2018, the FASB issued a practical expedient for land easements under the new lease guidance. The practical expedient permits an entity to elect the option to not evaluate land easements under the new guidance if they existed or expired before the adoption of the new lease guidance and were not previously accounted for as leases under the previous lease guidance. Once an entity adopts the new guidance, the entity should apply the new guidance on a prospective basis to all new or modified land easements. The Company is currently planning to adopt this practical expedient. The Company continues to monitor other &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;industry-specific issues as it relates to the regulated businesses but does not expect these issues to have a material impact on the Company's results of operations, financial position or disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2017-04 - Simplifying the Test for Goodwill Impairment &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In January&#160;2017, the FASB issued guidance on simplifying the test for goodwill impairment by eliminating Step&#160;2, which required an entity to measure the amount of impairment loss by comparing the implied fair value of reporting unit goodwill with the carrying amount of such goodwill. This guidance requires entities to perform a quantitative impairment test, previously Step&#160;1, to identify both the existence of impairment and the amount of impairment loss by comparing the fair value of a reporting unit to its carrying amount. Entities will continue to have the option of performing a qualitative assessment to determine if the quantitative impairment test is necessary. The guidance also requires additional disclosures if an entity has one or more reporting units with zero or negative carrying amounts of net assets. The guidance will be effective for the Company on January&#160;1, 2020, and must be applied on a prospective basis with early adoption permitted. The Company is evaluating the effects the adoption of the new guidance will have on its results of operations, financial position, cash flows and disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2018-07 - Improvements to Nonemployee Share-Based Payment Accounting &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In June&#160;2018, the FASB issued guidance on simplifying the accounting for nonemployee share-based payment transactions by expanding the scope of ASC 718, &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;"&gt;Compensation - Stock Compensation&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, to include share-based payment transactions for acquiring goods and services from nonemployees. The guidance will require nonemployee share-based payment awards be measured at the grant-date fair value of the equity instruments at the grant date. The guidance will be effective for the Company on January&#160;1, 2019, including interim periods, and must be applied using a modified retrospective approach with early adoption permitted. The modified retrospective approach requires an entity to record a cumulative-effect adjustment to retained earnings at the beginning of the year of adoption. The Company is evaluating the effects the adoption of the new guidance will have on its results of operations, financial position, cash flows and disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2018-13 - Changes to the Disclosure Requirements for Fair Value Measurement &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In August&#160;2018, the FASB issued guidance on modifying the disclosure requirements on fair value measurements as part of the disclosure framework project. The guidance modifies, among other things, the disclosures required for Level 3 fair value measurements, including the range and weighted average of significant unobservable inputs. The guidance removes, among other things, the disclosure requirement to disclose transfers between Levels 1 and 2. The guidance will be effective for the Company on January&#160;1, 2020, including interim periods, with early adoption permitted. Level 3 fair value measurement disclosures should be applied prospectively while all other amendments should be applied retrospectively. The Company is evaluating the effects the adoption of the new guidance will have on its disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2018-14 - Changes to the Disclosure Requirements for Defined Benefit Plans &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In August&#160;2018, the FASB issued guidance on modifying the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans as part of the disclosure framework project. The guidance removes disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The guidance adds, among other things, the requirement to include an explanation for significant gains and losses related to changes in benefit obligations for the period. The guidance removes, among other things, the disclosure requirement to disclose the amount of net periodic benefit costs to be amortized over the next fiscal year from accumulated other comprehensive income (loss) and the effects a one percentage point change in assumed health care cost trend rates will have on certain benefit components. The guidance will be effective for the Company on January&#160;1, 2021, and must be applied on a retrospective basis with early adoption permitted. The Company is evaluating the effects the adoption of the new guidance will have on the its disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2018-15 - Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In August&#160;2018, the FASB issued guidance on the accounting for implementation costs of a hosting arrangement that is a service contract. The guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract similar to the costs incurred to develop or obtain internal-use software and such capitalized costs to be expensed over the term of the hosting arrangement. Costs incurred during the preliminary and postimplementation stages should continue to be expensed as activities are performed. The capitalized costs are required to be presented on the balance sheet in the same line the prepayment for the fees associated with the hosting arrangement would be presented. In addition, the expense related to the capitalized implementation costs should be presented in the same line on the income statement as the fees associated with the hosting element of the arrangements. The guidance will be effective for the Company on January&#160;1, 2020, including interim periods, and may be applied on a retrospective or a prospective basis with early adoption permitted. The Company is evaluating the effects the adoption of the new guidance will have on the its results of operations, financial position, cash flows and disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;SEC File Number S7-15-16 - Disclosure Update and Simplification &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In October&#160;2018, the SEC published guidance in the Federal Register on disclosure updates and simplifications. The guidance removes disclosures that are no longer considered cost beneficial, duplicative of GAAP required disclosures, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The amendments are intended to facilitate disclosure of information to investors and simplify the compliance without significantly altering the total mix of information provided to investors. The guidance will be effective for the Company on November 5, 2018, including interim periods, and must be applied on a prospective basis. The Company is &lt;/span&gt;&lt;/div&gt;evaluating the effects the adoption of the new guidance will have on its disclosures, various sections of the Annual Report on Form 10-K for the year ended December 31, 2018, and future reports on Form 10-Q.</us-gaap:NewAccountingPronouncementsAndChangesInAccountingPrinciplesTextBlock>

The guidance provides for a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry specific guidance. In August&#160;2015, the FASB issued guidance deferring the effective date of the revenue guidance and allowing entities to &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;early adopt. With this decision, the guidance was effective for the Company on January&#160;1, 2018. Entities had the option of using either a full retrospective or modified retrospective approach to adopting the guidance. Under the modified retrospective approach, an entity recognizes the cumulative effect of initially applying the guidance with an adjustment to the opening balance of retained earnings in the period of adoption. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The Company adopted the guidance on January&#160;1, 2018, using the modified retrospective approach. The Company elected the practical expedient to not disclose the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied (or partially unsatisfied) as of the end of the reporting period, along with an explanation of when such revenue would be expected to be recognized. This practical expedient was used since the performance obligations are part of contracts with an original duration of one year or less. The Company also elected the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company otherwise would have recognized is one year or less. Upon completion of the Company's evaluation of contracts and methods of revenue recognition under the previous accounting guidance, the Company did not identify any material cumulative effect adjustments to be made to retained earnings. In addition, the Company has expanded revenue disclosures, both quantitatively and qualitatively, related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, as discussed in Note&#160;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;8&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;. The Company reviewed its revenue streams to evaluate the impact of this guidance and did not identify a significant change in the timing of revenue recognition, results of operations, financial position or cash flows. The Company reviewed its internal controls related to revenue recognition and disclosures and concluded that the guidance impacted certain business processes and controls. As such, the Company developed modifications to its internal controls for certain topics under the guidance as they apply to the Company and such modifications were not deemed to be significant.

As such, these contracts were still open and met the criteria for a cumulative effect adjustment.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2016-15 - Classification of Certain Cash Receipts and Cash Payments &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In August&#160;2016, the FASB issued guidance to clarify the classification of certain cash receipts and payments in the statement of cash flows. The guidance is intended to standardize the presentation and classification of certain transactions, including cash payments for debt prepayment or extinguishment, proceeds from insurance claim settlements and distributions from equity method investments. In addition, the guidance clarifies how to classify transactions that have characteristics of more than one class of cash flows. The Company adopted the guidance on January&#160;1, 2018, on a prospective basis. The guidance did not have a material effect on the Company's statement of cash flows.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2017-01 - Clarifying the Definition of a Business &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In January&#160;2017, the FASB issued guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The guidance provides a screen to determine when an integrated set of assets and activities is not a business. The guidance also affects other aspects of accounting, such as determining reporting units for goodwill testing and whether an entity has acquired or sold a business. The Company adopted the guidance on January&#160;1, 2018, on a prospective basis. The guidance did not have a material effect on the Company's results of operations, financial position, cash flows or disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2017-07 - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In March&#160;2017, the FASB issued guidance to improve the presentation of net periodic pension and net periodic postretirement benefit costs. The guidance required the service cost component to be presented in the income statement in the same line item or items as other compensation costs arising from services performed during the period. Other components of net periodic benefit cost shall be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. The guidance also only allows the service cost component to be capitalized.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The Company adopted the guidance on January&#160;1, 2018, on a retrospective basis. The guidance required the reclassification of all components of net periodic benefit costs, except for the service cost component, from operating expenses to other income on the Consolidated Statements of Income with no impact to earnings. As a result of the retrospective application of this change in accounting guidance, the Company reclassified &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$1.5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$4.5&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; from operation and maintenance expense to other income on the Consolidated Statements of Income for the &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;three and nine&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; months ended September&#160;30, 2017, respectively. The Company also reclassified unrealized gains on investments used to satisfy obligations under the defined benefit plans of &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$2.6&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$7.9&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; for the &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;three and nine&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; months ended September&#160;30, 2017, respectively, which were included in operation and maintenance expense, to other income on the Consolidated Statements of Income. The guidance did not have a material effect on the Company's results of operations, cash flows or disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2018-02 - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In February&#160;2018, the FASB issued guidance that allows an entity to reclassify the stranded tax effects resulting from the newly enacted federal corporate income tax rate from accumulated other comprehensive income (loss) to retained earnings. The guidance is effective for the Company on January&#160;1, 2019, including interim periods, with early adoption permitted. The guidance can be applied using one of two methods. One method is to record the reclassification of the stranded income taxes at the beginning of the period of adoption. The other method is to apply the guidance retrospectively to each period in which the income tax effects of the TCJA are recognized in accumulated other comprehensive income (loss). The Company early adopted the guidance on January&#160;1, 2018, and elected to reclassify the stranded income taxes at the beginning of the period. During the first quarter of 2018, the Company reclassified &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$7.9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; of stranded tax expense from accumulated other comprehensive loss to retained earnings. The guidance did not have a material effect on the Company's results of operations, cash flows or disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:10pt;font-weight:bold;"&gt;Recently issued accounting standards not yet adopted&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2016-02 - Leases &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In February&#160;2016, the FASB issued guidance regarding leases. The guidance requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet for operating and financing leases. The guidance remains largely the same for lessors, although some changes were made to better align lessor accounting with the new lessee accounting and to align with the revenue recognition standard. The guidance also requires additional disclosures, both quantitative and qualitative, related to operating and finance leases for the lessee and sales-type, direct financing and operating leases for the lessor. This guidance will be effective for the Company on January&#160;1, 2019, with early adoption permitted. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In July&#160;2018, the FASB issued ASU 2018-11 - &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;"&gt;Leases: Targeted Improvements,&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; an accounting standard update to ASU 2016-02. This ASU provides an entity the option to adopt the guidance using one of two modified retrospective approaches. An entity can adopt the guidance using the modified retrospective transition approach beginning in the earliest year presented in the financial statements. This method of adoption would require the restatement of prior periods reported and the presentation of lease disclosures under the new guidance for all periods reported. The additional transition method of adoption introduced by ASU 2018-11, allows entities the option to apply the guidance on the date of adoption by recognizing a cumulative effect adjustment to retained earnings during the period of adoption and does not require prior comparative periods to be restated. The Company is planning to adopt the standard on January&#160;1, 2019, utilizing the practical expedient that allows the Company to not reassess whether an expired or existing contract contains a lease, the classification of leases or initial direct costs, as well as the additional transition method of adoption applied on the date of adoption. The Company also plans to adopt a short-term leasing policy as the lessee where leases with a term of 12 months or less will not be included on the Consolidated Balance Sheet.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The Company formed a lease implementation team and is currently in the contract review and assessment phase to identify and evaluate contracts containing leases. Additionally, the team is implementing new and revising existing software to meet the reporting and disclosure requirements of the standard. The Company also has started to assess the impact the standard will have on its processes and internal controls and is identifying new and updating current processes. During the assessment phase, the Company is using various analytic methodologies to ensure the completeness of the lease inventory. The Company expects that most of the current operating leases will be subject to the guidance and recognized as operating lease liabilities and right-of-use assets on the Consolidated Balance Sheets upon adoption. During the fourth quarter of 2018, the Company will engage internal auditors to review and assess the completeness of the lease inventory and the effectiveness of the revised and new internal controls. The Company continues to evaluate the impact the new guidance will have on lease contracts where the Company is the lessor and, at this time, does not anticipate a significant impact. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In January&#160;2018, the FASB issued a practical expedient for land easements under the new lease guidance. The practical expedient permits an entity to elect the option to not evaluate land easements under the new guidance if they existed or expired before the adoption of the new lease guidance and were not previously accounted for as leases under the previous lease guidance. Once an entity adopts the new guidance, the entity should apply the new guidance on a prospective basis to all new or modified land easements. The Company is currently planning to adopt this practical expedient. The Company continues to monitor other &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;industry-specific issues as it relates to the regulated businesses but does not expect these issues to have a material impact on the Company's results of operations, financial position or disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2017-04 - Simplifying the Test for Goodwill Impairment &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In January&#160;2017, the FASB issued guidance on simplifying the test for goodwill impairment by eliminating Step&#160;2, which required an entity to measure the amount of impairment loss by comparing the implied fair value of reporting unit goodwill with the carrying amount of such goodwill. This guidance requires entities to perform a quantitative impairment test, previously Step&#160;1, to identify both the existence of impairment and the amount of impairment loss by comparing the fair value of a reporting unit to its carrying amount. Entities will continue to have the option of performing a qualitative assessment to determine if the quantitative impairment test is necessary. The guidance also requires additional disclosures if an entity has one or more reporting units with zero or negative carrying amounts of net assets. The guidance will be effective for the Company on January&#160;1, 2020, and must be applied on a prospective basis with early adoption permitted. The Company is evaluating the effects the adoption of the new guidance will have on its results of operations, financial position, cash flows and disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2018-07 - Improvements to Nonemployee Share-Based Payment Accounting &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In June&#160;2018, the FASB issued guidance on simplifying the accounting for nonemployee share-based payment transactions by expanding the scope of ASC 718, &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;"&gt;Compensation - Stock Compensation&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, to include share-based payment transactions for acquiring goods and services from nonemployees. The guidance will require nonemployee share-based payment awards be measured at the grant-date fair value of the equity instruments at the grant date. The guidance will be effective for the Company on January&#160;1, 2019, including interim periods, and must be applied using a modified retrospective approach with early adoption permitted. The modified retrospective approach requires an entity to record a cumulative-effect adjustment to retained earnings at the beginning of the year of adoption. The Company is evaluating the effects the adoption of the new guidance will have on its results of operations, financial position, cash flows and disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2018-13 - Changes to the Disclosure Requirements for Fair Value Measurement &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In August&#160;2018, the FASB issued guidance on modifying the disclosure requirements on fair value measurements as part of the disclosure framework project. The guidance modifies, among other things, the disclosures required for Level 3 fair value measurements, including the range and weighted average of significant unobservable inputs. The guidance removes, among other things, the disclosure requirement to disclose transfers between Levels 1 and 2. The guidance will be effective for the Company on January&#160;1, 2020, including interim periods, with early adoption permitted. Level 3 fair value measurement disclosures should be applied prospectively while all other amendments should be applied retrospectively. The Company is evaluating the effects the adoption of the new guidance will have on its disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2018-14 - Changes to the Disclosure Requirements for Defined Benefit Plans &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In August&#160;2018, the FASB issued guidance on modifying the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans as part of the disclosure framework project. The guidance removes disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The guidance adds, among other things, the requirement to include an explanation for significant gains and losses related to changes in benefit obligations for the period. The guidance removes, among other things, the disclosure requirement to disclose the amount of net periodic benefit costs to be amortized over the next fiscal year from accumulated other comprehensive income (loss) and the effects a one percentage point change in assumed health care cost trend rates will have on certain benefit components. The guidance will be effective for the Company on January&#160;1, 2021, and must be applied on a retrospective basis with early adoption permitted. The Company is evaluating the effects the adoption of the new guidance will have on the its disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;ASU 2018-15 - Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In August&#160;2018, the FASB issued guidance on the accounting for implementation costs of a hosting arrangement that is a service contract. The guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract similar to the costs incurred to develop or obtain internal-use software and such capitalized costs to be expensed over the term of the hosting arrangement. Costs incurred during the preliminary and postimplementation stages should continue to be expensed as activities are performed. The capitalized costs are required to be presented on the balance sheet in the same line the prepayment for the fees associated with the hosting arrangement would be presented. In addition, the expense related to the capitalized implementation costs should be presented in the same line on the income statement as the fees associated with the hosting element of the arrangements. The guidance will be effective for the Company on January&#160;1, 2020, including interim periods, and may be applied on a retrospective or a prospective basis with early adoption permitted. The Company is evaluating the effects the adoption of the new guidance will have on the its results of operations, financial position, cash flows and disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;SEC File Number S7-15-16 - Disclosure Update and Simplification &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In October&#160;2018, the SEC published guidance in the Federal Register on disclosure updates and simplifications. The guidance removes disclosures that are no longer considered cost beneficial, duplicative of GAAP required disclosures, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The amendments are intended to facilitate disclosure of information to investors and simplify the compliance without significantly altering the total mix of information provided to investors. The guidance will be effective for the Company on November 5, 2018, including interim periods, and must be applied on a prospective basis. The Company is &lt;/span&gt;&lt;/div&gt;evaluating the effects the adoption of the new guidance will have on its disclosures, various sections of the Annual Report on Form 10-K for the year ended December 31, 2018, and future reports on Form 10-Q.</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company is considered an agent for certain taxes collected from customers. As such, the Company presents revenues net of these taxes at the time of sale to be remitted to governmental authorities, including sales and use taxes.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The electric and natural gas distribution segments generate revenue from the sales of electric and natural gas products and services, which includes retail and transportation services. These segments establish a customer's retail or transportation service account based on the customer's application/contract for service, which indicates approval of a contract for service. The contract identifies an obligation to provide service in exchange for delivering or standing ready to deliver the identified commodity; and the customer is obligated to pay for the service as provided in the applicable tariff. The product sales are based on a fixed rate that includes a base and per-unit rate, which are included in approved tariffs as determined by state or federal regulatory agencies. The quantity of the commodity consumed or transported determines the total per-unit revenue. The service provided, along with the product consumed or transported, are a single performance obligation because both are required in combination to successfully transfer the contracted product or service to the customer. Revenues are recognized over time as customers receive and consume the products and services. The method of measuring progress toward the completion of the single performance &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;obligation is on a per-unit output method basis, with revenue recognized based on the direct measurement of the value to the customer of the goods or services transferred to date. For contracts governed by the Company&#x2019;s utility tariffs, amounts are billed monthly with the amount due between 15 and 22 days of receipt of the invoice depending on the applicable state&#x2019;s tariff. For other contracts not governed by tariff, payment terms are net thirty days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The pipeline and midstream segment generates revenue from providing natural gas transportation, gathering and underground storage services, as well as other energy-related services to both third parties and internal customers, largely the natural gas distribution segment. The pipeline and midstream segment establishes a contract with a customer based upon the customer&#x2019;s request for firm or interruptible natural gas transportation, storage or gathering service(s). The contract identifies an obligation for the segment to provide the requested service(s) in exchange for consideration from the customer over a specified term. Depending on the type of service(s) requested and contracted, the service provided may include transporting, gathering or storing an identified quantity of natural gas and/or standing ready to deliver or store an identified quantity of natural gas. Natural gas transportation, gathering and storage revenues are based on fixed rates, which may include reservation fees and/or per-unit commodity rates. The services provided by the segment are generally treated as single performance obligations satisfied over time simultaneous to when the service is provided and revenue is recognized. Rates for the segment&#x2019;s regulated services are based on its FERC approved tariff or customer negotiated rates on special projects, and rates for its non-regulated services are negotiated with its customers and set forth in the contract. For contracts governed by the company&#x2019;s tariff, amounts are billed on or before the ninth business day of the following month and the amount is due within twelve days of receipt of the invoice. For gathering contracts not governed by the tariff, amounts are due within twenty days of invoice receipt. For other contracts not governed by the tariff, payment terms are net thirty days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The construction materials and contracting segment generates revenue from contracting services and construction materials sales. This segment focuses on the vertical integration of its contracting services with its construction materials to support the aggregate based product lines. This segment provides contracting services to a customer when a contract has been signed by both the customer and a representative of the segment obligating a service to be provided in exchange for the consideration identified in the contract. The nature of the services this segment provides generally includes integrating a set of services and related construction materials into a single project to create a distinct bundle of goods and services, which the Company evaluates to determine whether a separate performance obligation exists. The transaction price is the original contract price plus any subsequent change orders and variable consideration. Examples of variable consideration that exist in this segment's contracts include liquidated damages; performance bonuses or incentives and penalties; claims; unapproved/unpriced change orders; and index pricing. The variable amounts usually arise upon achievement of certain performance metrics or change in project scope. The Company estimates the amount of revenue to be recognized on variable consideration using estimation methods that best predict the most likely amount of consideration the Company expects to be entitled to or expects to incur. The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Changes in circumstances could impact management's estimates made in determining the value of variable consideration recorded. The Company updates its estimate of the transaction price each reporting period and the effect of variable consideration on the transaction price is recognized as an adjustment to revenue on a cumulative catch-up basis. Revenue is recognized over time using the input method based on the measurement of progress on a project. The input method is the preferred method of measuring revenue because the costs incurred have been determined to represent the best indication of the overall progress toward the transfer of such goods or services promised to a customer. This segment also sells construction materials to third parties and internal customers. The contract for material sales is the use of a sales order or an invoice, which includes the pricing and payment terms. All material contracts contain a single performance obligation for the delivery of a single distinct product or a distinct separately identifiable bundle of products and services. Revenue is recognized at a point in time when the performance obligation has been satisfied with the delivery of the products or services. The warranties associated with the sales are those consistent with a standard warranty that the product meets certain specifications for quality or those required by law. For most contracts, amounts billed to customers are due within thirty days of receipt. There are no material obligations for returns, refunds or other similar obligations.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The construction services segment generates revenue from specialty contracting services which also includes the sale of construction equipment and other supplies. This segment provides specialty contracting services to a customer when a contract has been signed by both the customer and a representative of the segment obligating a service to be provided in exchange for the consideration identified in the contract. The nature of the services this segment provides generally includes multiple promised goods and services in a single project to create a distinct bundle of goods and services, which the Company evaluates to determine whether a separate performance obligation exists. The transaction price is the original contract price plus any subsequent change orders and variable consideration.

The Company believes this level of disaggregation best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. The table also includes a reconciliation of the disaggregated revenue by reportable segments.

The timing of invoicing to customers does not necessarily correlate with the timing of revenues being recognized under the cost&#x2010;to&#x2010;cost method of accounting. Contracts from contracting services are billed as work progresses in accordance with agreed upon contractual terms. Generally, billing to the customer occurs contemporaneous to revenue recognition. A variance in timing of the billings may result in a contract asset or a contract liability. A contract asset occurs when revenues are recognized under the cost-to-cost measure of progress, which exceeds amounts billed on uncompleted contracts. Such amounts will be billed as standard contract terms allow, usually based on various measures of performance or achievement. A contract liability occurs when there are billings in excess of revenues recognized under the cost-to-cost measure of progress on uncompleted contracts. Contract liabilities decrease as revenue is recognized from the satisfaction of the related performance obligation. The changes in contract assets and liabilities were as follows:&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:10pt;"&gt;&lt;div

Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company is considered an agent for certain taxes collected from customers. As such, the Company presents revenues net of these taxes at the time of sale to be remitted to governmental authorities, including sales and use taxes.&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The electric and natural gas distribution segments generate revenue from the sales of electric and natural gas products and services, which includes retail and transportation services. These segments establish a customer's retail or transportation service account based on the customer's application/contract for service, which indicates approval of a contract for service. The contract identifies an obligation to provide service in exchange for delivering or standing ready to deliver the identified commodity; and the customer is obligated to pay for the service as provided in the applicable tariff. The product sales are based on a fixed rate that includes a base and per-unit rate, which are included in approved tariffs as determined by state or federal regulatory agencies. The quantity of the commodity consumed or transported determines the total per-unit revenue. The service provided, along with the product consumed or transported, are a single performance obligation because both are required in combination to successfully transfer the contracted product or service to the customer. Revenues are recognized over time as customers receive and consume the products and services. The method of measuring progress toward the completion of the single performance &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;obligation is on a per-unit output method basis, with revenue recognized based on the direct measurement of the value to the customer of the goods or services transferred to date. For contracts governed by the Company&#x2019;s utility tariffs, amounts are billed monthly with the amount due between 15 and 22 days of receipt of the invoice depending on the applicable state&#x2019;s tariff. For other contracts not governed by tariff, payment terms are net thirty days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The pipeline and midstream segment generates revenue from providing natural gas transportation, gathering and underground storage services, as well as other energy-related services to both third parties and internal customers, largely the natural gas distribution segment. The pipeline and midstream segment establishes a contract with a customer based upon the customer&#x2019;s request for firm or interruptible natural gas transportation, storage or gathering service(s). The contract identifies an obligation for the segment to provide the requested service(s) in exchange for consideration from the customer over a specified term. Depending on the type of service(s) requested and contracted, the service provided may include transporting, gathering or storing an identified quantity of natural gas and/or standing ready to deliver or store an identified quantity of natural gas. Natural gas transportation, gathering and storage revenues are based on fixed rates, which may include reservation fees and/or per-unit commodity rates. The services provided by the segment are generally treated as single performance obligations satisfied over time simultaneous to when the service is provided and revenue is recognized. Rates for the segment&#x2019;s regulated services are based on its FERC approved tariff or customer negotiated rates on special projects, and rates for its non-regulated services are negotiated with its customers and set forth in the contract. For contracts governed by the company&#x2019;s tariff, amounts are billed on or before the ninth business day of the following month and the amount is due within twelve days of receipt of the invoice. For gathering contracts not governed by the tariff, amounts are due within twenty days of invoice receipt. For other contracts not governed by the tariff, payment terms are net thirty days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The construction materials and contracting segment generates revenue from contracting services and construction materials sales. This segment focuses on the vertical integration of its contracting services with its construction materials to support the aggregate based product lines. This segment provides contracting services to a customer when a contract has been signed by both the customer and a representative of the segment obligating a service to be provided in exchange for the consideration identified in the contract. The nature of the services this segment provides generally includes integrating a set of services and related construction materials into a single project to create a distinct bundle of goods and services, which the Company evaluates to determine whether a separate performance obligation exists. The transaction price is the original contract price plus any subsequent change orders and variable consideration. Examples of variable consideration that exist in this segment's contracts include liquidated damages; performance bonuses or incentives and penalties; claims; unapproved/unpriced change orders; and index pricing. The variable amounts usually arise upon achievement of certain performance metrics or change in project scope. The Company estimates the amount of revenue to be recognized on variable consideration using estimation methods that best predict the most likely amount of consideration the Company expects to be entitled to or expects to incur. The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Changes in circumstances could impact management's estimates made in determining the value of variable consideration recorded. The Company updates its estimate of the transaction price each reporting period and the effect of variable consideration on the transaction price is recognized as an adjustment to revenue on a cumulative catch-up basis. Revenue is recognized over time using the input method based on the measurement of progress on a project. The input method is the preferred method of measuring revenue because the costs incurred have been determined to represent the best indication of the overall progress toward the transfer of such goods or services promised to a customer. This segment also sells construction materials to third parties and internal customers. The contract for material sales is the use of a sales order or an invoice, which includes the pricing and payment terms. All material contracts contain a single performance obligation for the delivery of a single distinct product or a distinct separately identifiable bundle of products and services. Revenue is recognized at a point in time when the performance obligation has been satisfied with the delivery of the products or services. The warranties associated with the sales are those consistent with a standard warranty that the product meets certain specifications for quality or those required by law. For most contracts, amounts billed to customers are due within thirty days of receipt. There are no material obligations for returns, refunds or other similar obligations.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The construction services segment generates revenue from specialty contracting services which also includes the sale of construction equipment and other supplies. This segment provides specialty contracting services to a customer when a contract has been signed by both the customer and a representative of the segment obligating a service to be provided in exchange for the consideration identified in the contract. The nature of the services this segment provides generally includes multiple promised goods and services in a single project to create a distinct bundle of goods and services, which the Company evaluates to determine whether a separate performance obligation exists. The transaction price is the original contract price plus any subsequent change orders and variable consideration. Examples of variable consideration that exist in this segment's contracts include claims, unapproved/unpriced change orders, bonuses, incentives, penalties and liquidated damages. The variable amounts usually arise upon achievement of certain performance metrics or change in project scope. The Company estimates the amount of revenue to be recognized on variable consideration using estimation methods that best predict the most likely amount of consideration the Company expects to be entitled to or expects to incur. The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Changes in circumstances could impact management's estimates made in determining the value of variable consideration recorded. The Company updates its estimate of &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;the transaction price each reporting period and the effect of variable consideration on the transaction price is recognized as an adjustment to revenue on a cumulative catch-up basis. Revenue is recognized over time using the input method based on the measurement of progress on a project. The input method is the preferred method of measuring revenue because the costs incurred have been determined to represent the best indication of the overall progress toward the transfer of such goods or services promised to a customer. This segment also sells construction equipment and other supplies to third parties and internal customers. The contract for these sales is the use of a sales order or invoice, which includes the pricing and payment terms. All such contracts include a single performance obligation for the delivery of a single distinct product or a distinct separately identifiable bundle of products and services. Revenue is recognized at a point in time when the performance obligation has been satisfied with the delivery of the products or services. The warranties associated with the sales are those consistent with a standard warranty that the product meets certain specifications for quality or those required by law. For most contracts, amounts billed to customers are due within thirty days of receipt. There are no material obligations for returns, refunds or other similar obligations.&lt;/span&gt;&lt;/div&gt;The Company recognizes all other revenues when services are rendered or goods are delivered.</us-gaap:RevenueRecognitionPolicyTextBlock>

In June&#160;2018, the Company acquired Tri-City Paving, Inc., a general contractor and aggregate, asphalt and ready-mixed concrete supplier in Minnesota. In July&#160;2018, the Company acquired Molalla Redi-Mix and Rock Products, Inc., a producer of ready-mixed concrete in Oregon. As of September 30, 2018, the gross aggregate &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;consideration for these acquisitions was &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$27.9&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; in cash, subject to certain adjustments, and &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;713,948&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; shares of common stock with a market value of &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$20.1 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; as of the respective acquisition date. Due to the holding period restriction on the common stock, the share consideration has been discounted to a fair value of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$18.0&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, as reflected in the Company's financial statements. The acquisitions are subject to customary adjustments based on, among other things, the amount of cash, debt and working capital in the businesses as of the closing dates. The amounts included in the Consolidated Balance Sheets for these adjustments are considered provisional until final settlement has occurred.&lt;/span&gt;&lt;/div&gt;The above acquisitions are considered business combinations and the Company has preliminarily allocated the purchase price of the acquisitions to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition dates. The excess of the purchase price over the aggregate fair values was recorded as goodwill. The Company calculated the fair value of the assets acquired using the income, market or cost approach (or a combination thereof). Fair values for some of the assets were determined based on Level 3 inputs including estimated future cash flows, discount rates, growth rates, sales projections, retention rates and terminal values, all of which require significant management judgment and are susceptible to change. The purchase price allocation is based upon preliminary information and is subject to change if additional information about the facts and circumstances that existed at the acquisition date becomes available. The final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill. However, any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations. The discount rate used in calculating the fair value of the common stock issued was determined by a Black-Scholes-Merton model. The model used Level 2 inputs including risk-free interest rate, volatility range and dividend yield. The results of the acquired businesses have been included in the Company's construction materials and contracting segment and consolidated financial statements beginning on the acquisition dates. Pro forma financial amounts reflecting the effects of the above acquisitions are not presented, as such acquisitions were not material to the Company's financial position or results of operations.</us-gaap:BusinessCombinationDisclosureTextBlock>

WBI Energy and Calumet each previously owned &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;50&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent of the Dakota Prairie Refining membership interests and were equal members in building and operating Dakota Prairie Refinery.

The sale of the membership interests to Tesoro closed on June&#160;27, 2016. The sale of Dakota Prairie Refining reduced the Company&#x2019;s risk by decreasing exposure to commodity prices.

Gothic,sans-serif;font-size:9pt;"&gt;Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The fair value ASC establishes a hierarchy for grouping assets and liabilities, based on the significance of inputs. The estimated fair values of the Company's assets and liabilities measured on a recurring basis are determined using the market approach. The Company's Level&#160;2 money market funds are valued at the net asset value of shares held at the end of the quarter, based on published market quotations on active markets, or using other known sources including pricing from outside sources. The estimated fair value of the Company's Level&#160;2 mortgage-backed securities and U.S. Treasury securities are based on comparable market transactions, other observable inputs or other sources, including pricing from outside sources. The estimated fair value of the Company's Level&#160;2 insurance contract is based on contractual cash surrender values that are determined primarily by investments in managed separate accounts of the insurer. These amounts approximate fair value. The managed separate accounts are valued based on other observable inputs or corroborated market data.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;Though the Company believes the methods used to estimate fair value are consistent with those used by other market participants, the use of other methods or assumptions could result in a different estimate of fair value.

The internal reporting of these operating segments is defined based on the reporting and review process used by the Company's chief executive officer. The vast majority of the Company's operations are located within the United States.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The electric segment generates, transmits and distributes electricity in Montana, North Dakota, South Dakota and Wyoming. The natural gas distribution segment distributes natural gas in those states, as well as in Idaho, Minnesota, Oregon and Washington. These operations also supply related value-added services.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The pipeline and midstream segment provides natural gas transportation, underground storage and gathering services through regulated and nonregulated pipeline systems primarily in the Rocky Mountain and northern Great Plains regions of the United States. This segment also provides cathodic protection and other energy-related services.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The construction materials and contracting segment operations mine, process and sell construction aggregates (crushed stone, sand and gravel); produce and sell asphalt mix; and supply ready-mixed concrete. This segment focuses on vertical integration of its contracting services with its construction materials to support the aggregate based product lines including aggregate placement, asphalt and concrete paving, and site development and grading. Although not common to all locations, other products include the sale of cement, liquid asphalt for various commercial and roadway applications, various finished concrete products and other building materials and related contracting services. This segment operates in the central, southern and western United States and Alaska and Hawaii.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The construction services segment provides inside and outside specialty contracting services. Its outside services include design, construction and maintenance of overhead and underground electrical distribution and transmission lines, substations, external lighting, traffic signalization, and gas pipelines, as well as utility excavation and the manufacture and distribution of transmission line construction equipment. Its inside services include design, construction and maintenance of electrical and communication wiring and infrastructure, fire suppression systems, and mechanical piping and services. This segment also constructs and maintains renewable energy projects. These specialty contracting services are provided to utilities and large manufacturing, commercial, industrial, institutional and government customers. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The Other category includes the activities of Centennial Capital, which insures various types of risks as a captive insurer for certain of the Company's subsidiaries. The function of the captive insurer is to fund the self-insured layers of the insured Company's general liability, automobile liability, pollution liability and other coverages. Centennial Capital also owns certain real and personal property. The Other category also includes certain general and administrative costs (reflected in operation and maintenance expense) and interest expense which were previously allocated to the refining business and Fidelity and do not meet the criteria for income (loss) from discontinued operations. The Other category also includes Centennial Resources' former investment in Brazil.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;Discontinued operations includes the results and supporting activities of Dakota Prairie Refining and Fidelity other than certain general and administrative costs and interest expense as described above.

The Company files for rate adjustments to seek recovery of operating costs and capital investments, as well as reasonable returns as allowed by regulators. The Company's most recent cases by jurisdiction are discussed in the following paragraphs. The jurisdictions in which the Company provides service have requested the Company furnish plans for the effect of the reduced corporate tax rate due to the enactment of the TCJA which may impact the Company's rates. The following paragraphs include additional details and statuses of each open request.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;"&gt;MNPUC&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On December&#160;29, 2017, the MNPUC issued a notice of investigation related to tax changes with the enactment of the TCJA. On January&#160;19, 2018, the MNPUC issued a notice of request for information, commission planning meeting and subsequent comment period. Pursuant to the notice, Great Plains provided preliminary impacts of the TCJA on January&#160;30, 2018. On &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;March&#160;2, 2018, Great Plains submitted its initial filing addressing the impacts of the TCJA advocating existing rates are reasonable and a reduction in rates is not warranted. On August 9, 2018, the MNPUC ruled that Great Plains reduce rates to reflect TCJA impacts and to also provide a one-time refund that captures the TCJA impacts from January 1, 2018 through the implementation date of new rates. To date, an order by the MNPUC has not been issued. This matter is pending before the MNPUC.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;"&gt;MTPSC&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On December&#160;27, 2017, the MTPSC requested Montana-Dakota identify a plan for the impacts of the TCJA and to file a proposal for the impacts on the electric segment by March&#160;31, 2018. On April&#160;2, 2018, Montana-Dakota submitted its plan requesting the MTPSC recognize the identified need for additional rate relief and to consider the effects of the TCJA in a general electric rate case to be submitted by September&#160;30, 2018. Montana-Dakota submitted the general electric rate case on September 28, 2018, as discussed below. A hearing is scheduled for December 4, 2018. This matter is pending before the MTPSC.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On September 28, 2018, Montana-Dakota filed an application with the MTPSC for an electric rate increase of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$11.9&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; annually or approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;18.9&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; percent above current rates. The requested increase is primarily to recover investments in facilities to enhance safety and reliability and the depreciation and taxes associated with the increase in investment. The increase was offset by tax savings related to the TCJA. Montana-Dakota requested an interim increase of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$4.6&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; or approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;7.3&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; percent, subject to refund. This matter is pending before the MTPSC.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;"&gt;NDPSC&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On July&#160;21, 2017, Montana-Dakota filed an application with the NDPSC for a natural gas rate increase of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$5.9&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; annually or approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;5.4&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent above current rates. The requested increase is primarily to recover the increased investment in distribution facilities to enhance system safety and reliability and the depreciation and taxes associated with the increase in investment. Montana-Dakota also introduced a SSIP and the proposed adjustment mechanism required to fund the SSIP. Montana-Dakota requested an interim increase of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$4.6&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; or approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;4.2&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent, subject to refund. On September&#160;6, 2017, the NDPSC approved the request for interim rates effective with service rendered on or after September&#160;19, 2017. On February&#160;14, 2018, Montana-Dakota filed a revised interim increase request of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$2.7&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, subject to refund, incorporating the estimated impacts of the TCJA reduction in the federal corporate income tax rate. On March&#160;1, 2018, the updated interim rates were implemented. The impact of the TCJA was submitted as part of a rebuttal testimony identifying a reduction of the adjusted revenue requirement to approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$3.6&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;. A hearing was held May&#160;30, 2018 through June&#160;1, 2018. On July&#160;19, 2018, a settlement was filed reflecting a revised annual revenue increase of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$2.5&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; or approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;2.3&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent. The proposed adjustment mechanism to fund the SSIP was not included in the settlement and will be decided on separately by the NDPSC. On September&#160;26, 2018, the NDPSC issued an order approving the settlement as filed but did not approve the SSIP recovery mechanism. On October 5, 2018, Montana-Dakota submitted a compliance filing, which included a refund plan for the interim amount to be refunded to customers. This matter is pending before the NDPSC.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On January&#160;10, 2018, the NDPSC issued a general order initiating the investigation into the effects of the TCJA. The order required regulatory deferral accounting on the impacts of the TCJA and for companies to file comments and the expected impacts. On February&#160;15, 2018, Montana-Dakota filed a summary of the primary impacts of the TCJA on the electric and natural gas utilities. On March&#160;9, 2018, Montana-Dakota submitted a request to decrease its electric rates by &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$7.2&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; or &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;3.9&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent annually. On August 10, 2018, a settlement agreement was filed requesting a decrease in rates of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$8.4&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;. On September&#160;26, 2018, the NDPSC issued an order approving the settlement along with requiring an additional adjustment to the rates to return 100&#160;percent of the tax-effective 2018 excess deferred income taxes. On October 10, 2018, Montana-Dakota submitted a compliance filing, which included a refund plan for the interim amount to be refunded to customers. This matter is pending before the NDPSC.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;"&gt;OPUC&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On December&#160;29, 2017, Cascade filed a request with the OPUC to use deferral accounting for the 2018 net benefits associated with the implementation of the TCJA. This matter is pending before the OPUC.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On May&#160;31, 2018, Cascade filed a general rate case with the OPUC requesting an overall increase of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$2.3&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; or approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;3.5&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent on an annual basis, which incorporates the impact of the TCJA. This matter is pending before the OPUC. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;"&gt;SDPUC&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On December&#160;29, 2017, the SDPUC issued an order initiating the investigation into the effects of the TCJA. The order required Montana-Dakota to provide comments by February&#160;1, 2018, regarding the general effects of the TCJA on the cost of service in South Dakota and possible mechanisms for adjusting rates. The order also stated that all rates impacted by the federal income tax shall be adjusted effective January&#160;1, 2018, subject to refund. On May&#160;4, 2018 and June&#160;2, 2018, Montana-Dakota submitted detailed plans to address the TCJA impacts on the natural gas and electric utilities, respectively, to the SDPUC staff. On September 28, 2018, a settlement agreement was submitted to the SDPUC reflecting a proposal to refund approximately&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$600,000&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; to electric customers and approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$1.3&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; to natural gas customers. These refunds reflect the impact of the &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;TCJA on 2018. On October 23, 2018, an order was issued by the SDPUC approving the settlement agreement. Proposed rate changes to reflect 2018 pro forma results and the TCJA impacts will be submitted by December 1, 2018. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;"&gt;WUTC&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On August&#160;31, 2017, Cascade filed an application with the WUTC for a natural gas rate increase of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$5.9&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; annually or approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;2.7&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent above current rates. The requested increase includes costs associated with increased infrastructure investment and the associated operating expenses. Also included in the request is recovery of operation and maintenance costs associated with a maximum allowable operating pressure validation plan. On January&#160;3, 2018, the WUTC filed a bench request requiring Cascade to provide information related to the impacts of the TCJA on Cascade's revenue requirement and a proposed ratemaking treatment of those impacts. On March&#160;23, 2018, Cascade filed its rebuttal testimony revising the revenue requirement to a decrease of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$1.7&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; annually, which includes the impacts of the TCJA. On May&#160;17, 2018, Cascade, the WUTC staff and interveners in the case reached a settlement on all matters in the rate case except the treatment of interim tax benefits for the period January&#160;1, 2018 through July&#160;31, 2018. The settlement included an overall annual rate reduction of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$2.9&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; or approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;1.4&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent plus specific tariffs passing excess deferred income taxes back to customers totaling approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$2.5&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;. On July&#160;20, 2018, the WUTC approved the settlement reflecting a decrease in annual revenues, as well as refunding an additional &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$1.6&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; for the interim tax benefits for the period of January&#160;1, 2018 through July&#160;31, 2018. The refund of excess deferred income taxes and interim tax benefits is over a fifteen month period. These changes were effective August&#160;1, 2018.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On June 1, 2018, Cascade filed its annual pipeline cost recovery mechanism requesting an increase in annual revenue of &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$2.3&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; or approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;1.1&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent. On October 11&#160;2018, Cascade filed a revised increase in annual revenue of &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$2.1&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; or approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;1.0&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent. The increase will go into effect on November&#160;1, 2018. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;"&gt;WYPSC&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;On December&#160;29, 2017, the WYPSC issued a general order requiring regulatory deferral accounting on the impacts of the TCJA. A technical conference was held on February&#160;6, 2018, to discuss the implications of the TCJA. On March&#160;23, 2018, the WYPSC issued an order requiring all public utilities to submit an initial assessment of the overall effects on the TCJA on their rates by March&#160;30, 2018. On March&#160;30, 2018, Montana-Dakota submitted its initial assessment indicating a rate reduction for its electric rates in the amount of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$1.1&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; annually or approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;4.2&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent. Revised electric rates reflecting this reduction were submitted to the WYPSC on June&#160;13, 2018. Montana-Dakota reported its natural gas earnings do not support a decrease in rates and requested the WYPSC allow the impacts of the TCJA be addressed in a natural gas rate case to be submitted by June&#160;1, 2019. Both matters are pending before the WYPSC.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;"&gt;FERC&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;Montana-Dakota and certain MISO Transmission Owners with projected rates submitted a filing to the FERC on February&#160;1, 2018, requesting the FERC to waive certain provisions of the MISO tariff in order for Montana-Dakota and certain MISO Transmission Owners with projected rates to revise their rates to reflect the reduction in the corporate tax rate. Under the MISO tariff, rates are to be changed only on an annual basis with any changes reflected in subsequent true-ups. On March&#160;15, 2018, the FERC approved the waiver request and new rates reflecting the effects of the TCJA were implemented by MISO on March&#160;1, 2018. MISO also retroactively re-billed the January and February 2018 services to reflect the new rates. On September 4, 2018, Montana-Dakota filed an update to its transmission formula rate under the MISO tariff for the multivalue project for &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$12.5&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, which is effective January 1, 2019.&lt;/span&gt;&lt;/div&gt;On July&#160;18, 2018, the FERC issued a final rule on Rate Changes Relating to Federal Income Tax Rate reductions resulting from the TCJA which requires natural gas pipeline companies to make a one-time informational filing to evaluate the impact of the lower corporate income tax rate and also select one of four options presented by the FERC to address the impact. In accordance with WBI Energy Transmission&#x2019;s offer of settlement and stipulation and agreement with the FERC dated June&#160;4, 2014, the Company is to make a filing with new proposed rates to be effective no later than May&#160;1, 2019. On October 31, 2018, the Company filed a rate case with the FERC with rates effective May 1, 2019. Due to the timing of the rate case filing, the Company will be exempt from the one-time informational filing required by the FERC&#x2019;s final rule.</us-gaap:PublicUtilitiesDisclosureTextBlock>

The Company accrues a liability for those contingencies when the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Company does not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is probable or reasonably possible and which are material, the Company discloses the nature of the contingency and, in some circumstances, an estimate of the possible loss. Accruals are based on the best information available, but in certain situations management is unable to estimate an amount or range of a reasonably possible loss including, but not limited to when: (1) the damages are unsubstantiated or indeterminate, (2) the proceedings are in the early stages, (3) numerous parties are involved, or (4) the matter involves novel or unsettled legal theories. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The Company accrued liabilities of &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$30.4&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$34.3&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$35.4&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, which have not been discounted, including liabilities held for sale, for contingencies, including litigation, production taxes, royalty claims and environmental matters at &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;September&#160;30, 2018&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;2017&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, and &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;December&#160;31, 2017&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, respectively. This includes amounts that have been accrued for matters discussed in Environmental matters within this note. The Company will continue to monitor each matter and adjust accruals as might be warranted based on new information and further developments. Management believes that the outcomes with respect to probable and reasonably possible losses in excess of the amounts accrued, net of insurance recoveries, while uncertain, either cannot be estimated or will not have a material effect upon the Company's financial position, results of operations or cash flows. Unless otherwise required by GAAP, legal costs are expensed as they are incurred.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:10pt;font-weight:bold;"&gt;Environmental matters&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;Portland Harbor Site &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In December 2000, Knife River&#160;- Northwest was named by the EPA as a PRP in connection with the cleanup of a riverbed site adjacent to a commercial property site acquired by Knife River&#160;- Northwest from Georgia-Pacific West, Inc. in 1999. The riverbed site is part of the Portland, Oregon, Harbor Superfund Site. The EPA wants responsible parties to share in the cleanup of sediment contamination in the Willamette River. To date, costs of the overall remedial investigation and feasibility study of the harbor site are being recorded, and initially paid, through an administrative consent order by the LWG, a group of several entities, which does not include Knife River&#160;- Northwest or Georgia-Pacific West, Inc. Investigative costs are indicated to be in excess of &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$100&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;. On January&#160;6, 2017, Region&#160;10 of the EPA issued an ROD with its selected remedy for cleanup of the in-river portion of the site. Implementation of the remedy is expected to take up to 13&#160;years with a present value cost estimate of approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$1&#160;billion&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;. Corrective action will not be taken until remedial design/remedial action plans are approved by the EPA. Knife River&#160;- Northwest also received notice in January 2008 that the Portland Harbor Natural Resource Trustee Council intends to perform an injury assessment to natural resources resulting from the release of hazardous substances at the Harbor Superfund Site. The Portland Harbor Natural Resource Trustee Council indicates the injury determination is appropriate to facilitate early settlement of damages and restoration for natural resource injuries. It is not possible to estimate the costs of natural resource damages until an assessment is completed and allocations are undertaken.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;Based upon a review of the Portland Harbor sediment contamination evaluation by the Oregon DEQ and other information available, Knife River&#160;- Northwest does not believe it is a responsible party. In addition, Knife River&#160;- Northwest has notified Georgia-Pacific West, Inc., that it intends to seek indemnity for liabilities incurred in relation to the above matters pursuant to the terms of their sale agreement. Knife River&#160;- Northwest has entered into an agreement tolling the statute of limitations in connection with the LWG's potential claim for contribution to the costs of the remedial investigation and feasibility study. By letter in March 2009, LWG stated its intent to file suit against Knife River&#160;- Northwest and others to recover LWG's investigation costs to the extent Knife River&#160;- Northwest cannot demonstrate its non-liability for the contamination or is unwilling to participate in an alternative dispute resolution process that has been established to address the matter. At this time, Knife River&#160;- Northwest has agreed to participate in the alternative dispute resolution process.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The Company believes it is not probable that it will incur any material environmental remediation costs or damages in relation to the above referenced matter.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;Manufactured Gas Plant Sites &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;There are three claims against Cascade for cleanup of environmental contamination at manufactured gas plant sites operated by Cascade's predecessors. The accruals related to these claims are reflected in regulatory assets.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The first claim is for contamination at a site in Eugene, Oregon which was received in 1995. The Oregon DEQ released an ROD in January 2015 that selected a remediation alternative for the site as recommended in an earlier staff report. The total estimated cost for the selected remediation, including long-term maintenance, is approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$3.5&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; of which &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$400,000&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; has been incurred. Cascade and other PRPs will share in the cleanup costs with Cascade expecting to pay approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;50&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&#160;percent of the remediation and maintenance costs. Cascade has an accrual balance of &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$1.6&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; for remediation of this site. In January 2013, the OPUC approved Cascade's application to defer environmental remediation costs at the Eugene site for a period of 12&#160;months starting November&#160;30, 2012. Cascade received orders reauthorizing the deferred accounting for the 12-month periods starting November&#160;30, 2013, December&#160;1, 2014, December&#160;1, 2015, December&#160;1, 2016 and December&#160;1, 2017.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The second claim is for contamination at the Bremerton Gasworks Superfund Site in Bremerton, Washington which was received in 1997. A preliminary investigation has found soil and groundwater at the site contain contaminants requiring further investigation and cleanup. The EPA conducted a Targeted Brownfields Assessment of the site and released a report summarizing the results of that assessment in August 2009. The assessment confirms that contaminants have affected soil and groundwater at the site, as well as sediments in the adjacent Port Washington Narrows. Alternative remediation options have been identified with preliminary cost estimates ranging from &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$340,000&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; to &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$6.4&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;. Data developed through the assessment and previous investigations indicates the contamination likely derived from multiple, different sources and multiple current and former owners of properties and businesses in the vicinity of the site may be responsible for the contamination. In April 2010, the Washington DOE issued notice it considered Cascade a PRP for hazardous substances at the site. In May 2012, the EPA added the site to the National Priorities List of Superfund sites. Cascade has entered into an administrative settlement agreement and consent order with the EPA regarding the scope and schedule for a remedial investigation and feasibility study for the site. Current estimates for the cost to complete the remedial investigation and feasibility study are approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$7.6&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; of which &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$2.7&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; has been incurred. Cascade has accrued &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$4.9&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; for the remedial investigation and feasibility study, as well as &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$6.4&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; for remediation of this site; however, the accrual for remediation costs will be reviewed and adjusted, if necessary, after completion of the remedial investigation and feasibility study. In April 2010, Cascade filed a petition with the WUTC for authority to defer the &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;costs incurred in relation to the environmental remediation of this site. The WUTC approved the petition in September 2010, subject to conditions set forth in the order.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The third claim is for contamination at a site in Bellingham, Washington. Cascade received notice from a party in May 2008 that Cascade may be a PRP, along with other parties, for contamination from a manufactured gas plant owned by Cascade and its predecessor from about 1946 to 1962. Other PRPs reached an agreed order and work plan with the Washington DOE for completion of a remedial investigation and feasibility study for the site. A feasibility study prepared for one of the PRPs in March 2018 identifies five cleanup action alternatives for the site with estimated costs ranging from &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$8.0&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; to &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$20.4&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; with a selected preferred alternative having an estimated total cost of &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$9.3&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;. Cascade believes its proportional share of any liability will be relatively small in comparison to other PRPs. The plant manufactured gas from coal between approximately 1890 and 1946. In 1946, shortly after Cascade's predecessor acquired the plant, it converted the plant to a propane-air gas facility. There are no documented wastes or by-products resulting from the mixing or distribution of propane-air gas. Cascade has recorded an accrual for this site for an amount that is not material.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;Cascade has received notices from and entered into agreement with certain of its insurance carriers that they will participate in defense of Cascade for certain of the contamination claims subject to full and complete reservations of rights and defenses to insurance coverage. To the extent these claims are not covered by insurance, Cascade intends to seek recovery through the OPUC and WUTC of remediation costs in its natural gas rates charged to customers.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:10pt;font-weight:bold;"&gt;Guarantees&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In June 2016, WBI Energy sold all of the outstanding membership interests in Dakota Prairie Refining. In connection with the sale, Centennial agreed to continue to guarantee certain debt obligations of Dakota Prairie Refining which totaled $&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;49.9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; at &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;September&#160;30, 2018&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, and were expected to mature in 2023. Tesoro agreed to indemnify Centennial for any losses and litigation expenses arising from the guarantee. The estimated fair value of the indemnity asset is reflected in deferred charges and other assets - other and the guarantee liability is reflected in other accrued liabilities and deferred credits and other liabilities - other, on the Consolidated Balance Sheets. Continuation of the guarantee was required as a condition to the sale of Dakota Prairie Refining. On October 17, 2018, Centennial was released from this guarantee of certain debt obligations of Dakota Prairie Refining.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In 2009, multiple sale agreements were signed to sell the Company's ownership interests in the Brazilian Transmission Lines. In connection with the sale, Centennial agreed to guarantee payment of any indemnity obligations of certain of the Company's indirect wholly owned subsidiaries who were the sellers in three purchase and sale agreements for periods ranging up to 10&#160;years from the date of sale. The guarantees were required by the buyers as a condition to the sale of the Brazilian Transmission Lines.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;Certain subsidiaries of the Company have outstanding guarantees to third parties that guarantee the performance of other subsidiaries of the Company. These guarantees are related to construction contracts, insurance deductibles and loss limits, and certain other guarantees. At &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;September&#160;30, 2018&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, the fixed maximum amounts guaranteed under these agreements aggregated &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$197.2&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;. The amounts of scheduled expiration of the maximum amounts guaranteed under these agreements aggregate to &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$1.1 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; in &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;2018&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;; &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$114.9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; in &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;2019&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;; &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$74.2 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; in &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;2020&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;; &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$500,000&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; in &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;2021&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;; &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$500,000&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; in &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;2022&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;; &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$2.0 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; thereafter; and &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$4.0&#160;million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, which has no scheduled maturity date.

In the event of default under these letter of credit obligations, the subsidiary guaranteeing the letter of credit would be obligated for reimbursement of payments made under the letter of credit.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In addition, Centennial, Knife River and MDU Construction Services have issued guarantees to third parties related to the routine purchase of maintenance items, materials and lease obligations for which no fixed maximum amounts have been specified. These guarantees have no scheduled maturity date. In the event a subsidiary of the Company defaults under these obligations, Centennial, Knife River or MDU Construction Services would be required to make payments under these guarantees. Any amounts outstanding by subsidiaries of the Company were reflected on the Consolidated Balance Sheet at &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;September&#160;30, 2018&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;In the normal course of business, Centennial has surety bonds related to construction contracts and reclamation obligations of its subsidiaries. In the event a subsidiary of Centennial does not fulfill a bonded obligation, Centennial would be responsible to the surety bond company for completion of the bonded contract or obligation. A large portion of the surety bonds is expected to expire within the next 12&#160;months; however, Centennial will likely continue to enter into surety bonds for its subsidiaries in the future. At &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;September&#160;30, 2018&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, approximately &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$619.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; of surety bonds were outstanding, which were not reflected on the Consolidated Balance Sheet.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:10pt;font-weight:bold;"&gt;Variable interest entities&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The Company evaluates its arrangements and contracts with other entities to determine if they are VIEs and if so, if the Company is the primary beneficiary.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;"&gt;Fuel Contract&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt; Coyote Station entered into a coal supply agreement with Coyote Creek that provides for the purchase of coal necessary to supply the coal requirements of the Coyote Station for the period May 2016 through December 2040. Coal purchased under the coal supply agreement is reflected in inventories on the Company's Consolidated Balance Sheets and is recovered from customers as a component of electric fuel and purchased power.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;The coal supply agreement creates a variable interest in Coyote Creek due to the transfer of all operating and economic risk to the Coyote Station owners, as the agreement is structured so that the price of the coal will cover all costs of operations, as well as future reclamation costs. The Coyote Station owners are also providing a guarantee of the value of the assets of Coyote Creek as they would be required to buy the assets at book value should they terminate the contract prior to the end of the contract term and are providing a guarantee of the value of the equity of Coyote Creek in that they are required to buy the entity at the end of the contract term at equity value. Although the Company has determined that Coyote Creek is a VIE, the Company has concluded that it is not the primary beneficiary of Coyote Creek because the authority to direct the activities of the entity is shared by the four unrelated owners of the Coyote Station, with no primary beneficiary existing. As a result, Coyote Creek is not required to be consolidated in the Company's financial statements.&lt;/span&gt;&lt;/div&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;At &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;September&#160;30, 2018&lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;, the Company's exposure to loss as a result of the Company's involvement with the VIE, based on the Company's ownership percentage, was &lt;/span&gt;&lt;span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"&gt;&lt;span&gt;$39.2&#160;million&lt;/span&gt;&lt;/span&gt;.</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

The Company accrues a liability for those contingencies when the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Company does not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is probable or reasonably possible and which are material, the Company discloses the nature of the contingency and, in some circumstances, an estimate of the possible loss. Accruals are based on the best information available, but in certain situations management is unable to estimate an amount or range of a reasonably possible loss including, but not limited to when: (1) the damages are unsubstantiated or indeterminate, (2) the proceedings are in the early stages, (3) numerous parties are involved, or (4) the matter involves novel or unsettled legal theories.</us-gaap:CommitmentsAndContingenciesPolicyTextBlock>

Interim financial statements do not include all disclosures provided in annual financial statements and, accordingly, these financial statements should be read in conjunction with those appearing in the </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">2017</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> Annual Report. The information is unaudited but includes all adjustments that are, in the opinion of management, necessary for a fair presentation of the accompanying consolidated interim financial statements and are of a normal recurring nature. Depreciation, depletion and amortization expense is reported separately on the Consolidated Statements of Income and therefore is excluded from the other line items within operating expenses. Management has also evaluated the impact of events occurring after </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">September&#160;30, 2018</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, up to the date of issuance of these consolidated interim financial statements.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">On December 22, 2017, President Trump signed into law the TCJA which includes lower corporate tax rates, repealing the domestic production deduction, disallowance of immediate expensing for regulated utility property and modifying or repealing many other business deductions and credits. The reduction in the corporate tax rate was effective on January&#160;1, 2018, reducing the Company's income tax expense for 2018. The Company continues to review the components of the TCJA and the impact on the Company's consolidated financial statements and related disclosures for 2018 and thereafter. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">While the Company was able to make reasonable estimates of the impact of the reduction in corporate tax rate on the Company's net deferred tax liabilities during the fourth quarter of 2017, such estimates may be affected by other analyses related to the TCJA, including, but not limited to, the state tax effect of adjustments to federal temporary differences and the calculation of deemed repatriation of deferred foreign income. The final transition impacts of the TCJA may differ from amounts disclosed, possibly materially, due to, among other things, interpretations, legislative action to address questions, changes in accounting standards for income taxes or related interpretations, or updates or changes to estimates the Company has utilized to calculate the transition impacts. The SEC has issued rules that would allow for a measurement period of up to one year after the enactment date of the TCJA to finalize the recording of the related tax impacts, of which there were no such material adjustments during the nine months ended September 30, 2018. The Company currently anticipates finalizing and recording any resulting adjustments by December&#160;31, 2018, which will be included in income from continuing operations. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Due to the enactment of the TCJA, the regulated jurisdictions in which the Company's regulated businesses provide service have requested the Company furnish plans for the effect of the reduced corporate tax rate, which may impact the Company's rates to customers. Therefore, the Company has reserved for such impacts as an offset to revenue in certain jurisdictions. The Company will continue to make changes to reserve balances as new information becomes available. For more information on the details and statuses of the open requests, see Note&#160;</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">16</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Effective January&#160;1, 2018, the Company adopted the requirements of the revenue from contracts with customers guidance following the modified retrospective method, as discussed in Notes </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">6</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> and </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">8</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. As such, results for reporting periods beginning January&#160;1, 2018, are presented under the new guidance, while prior period amounts are not adjusted and continue to be reported in accordance with the historic accounting for revenue recognition. Based on the Company's analysis, the Company did not identify a significant change in the timing of revenue recognition under the new guidance as compared to the historic accounting for revenue recognition.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Certain prior year amounts have been reclassified to conform to the current year presentation in the consolidated financial statements related to the retrospective adoption of the FASB guidance to improve the presentation of net periodic pension and net periodic postretirement benefit costs, which was effective on January 1, 2018. The components of net periodic pension and postretirement costs, other than service costs, were reclassified from operating expenses to other income on the Consolidated Statements of Income, as discussed in Note&#160;</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">6</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">.</span></div><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The assets and liabilities for the Company's discontinued operations have been classified as held for sale and the results of operations are shown in income (loss) from discontinued operations, other than certain general and administrative costs and interest expense which do not meet the criteria for income (loss) from discontinued operations. At the time the assets were classified as held for sale, depreciation, depletion and amortization expense was no longer recorded. Unless otherwise indicated, the amounts presented in the accompanying notes to the consolidated financial statements relate to the Company's continuing operations. For more information on the Company's discontinued operations, see Note&#160;</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">10</span>.<span></span>

The guidance provides for a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry specific guidance. In August&#160;2015, the FASB issued guidance deferring the effective date of the revenue guidance and allowing entities to </span></div><div style="line-height:120%;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">early adopt. With this decision, the guidance was effective for the Company on January&#160;1, 2018. Entities had the option of using either a full retrospective or modified retrospective approach to adopting the guidance. Under the modified retrospective approach, an entity recognizes the cumulative effect of initially applying the guidance with an adjustment to the opening balance of retained earnings in the period of adoption. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company adopted the guidance on January&#160;1, 2018, using the modified retrospective approach. The Company elected the practical expedient to not disclose the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied (or partially unsatisfied) as of the end of the reporting period, along with an explanation of when such revenue would be expected to be recognized. This practical expedient was used since the performance obligations are part of contracts with an original duration of one year or less. The Company also elected the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company otherwise would have recognized is one year or less. Upon completion of the Company's evaluation of contracts and methods of revenue recognition under the previous accounting guidance, the Company did not identify any material cumulative effect adjustments to be made to retained earnings. In addition, the Company has expanded revenue disclosures, both quantitatively and qualitatively, related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, as discussed in Note&#160;</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">8</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. The Company reviewed its revenue streams to evaluate the impact of this guidance and did not identify a significant change in the timing of revenue recognition, results of operations, financial position or cash flows. The Company reviewed its internal controls related to revenue recognition and disclosures and concluded that the guidance impacted certain business processes and controls. As such, the Company developed modifications to its internal controls for certain topics under the guidance as they apply to the Company and such modifications were not deemed to be significant. Results for reporting periods beginning after December&#160;31, 2017, are presented under the new guidance, while prior period amounts are not adjusted and continue to be reported in accordance with historic accounting for revenue recognition.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Under the modified retrospective approach, the guidance was applied only to contracts that were not completed as of January&#160;1, 2018. Therefore, the Company recognized the cumulative effect of initially applying the guidance with an adjustment to the opening balance of retained earnings at January&#160;1, 2018. For the nine months ended September&#160;30, </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">2018</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, there were </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>no</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> material impacts to the financial statements as a result of applying the guidance.

Other components of net periodic benefit cost shall be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. The guidance also only allows the service cost component to be capitalized.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company adopted the guidance on January&#160;1, 2018, on a retrospective basis. The guidance required the reclassification of all components of net periodic benefit costs, except for the service cost component, from operating expenses to other income on the Consolidated Statements of Income with no impact to earnings. As a result of the retrospective application of this change in accounting guidance, the Company reclassified </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$1.5 million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> and </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$4.5&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> from operation and maintenance expense to other income on the Consolidated Statements of Income for the </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">three and nine</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> months ended September&#160;30, 2017, respectively. The Company also reclassified unrealized gains on investments used to satisfy obligations under the defined benefit plans of </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$2.6&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> and </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$7.9&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> for the </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">three and nine</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> months ended September&#160;30, 2017, respectively, which were included in operation and maintenance expense, to other income on the Consolidated Statements of Income. The guidance did not have a material effect on the Company's results of operations, cash flows or disclosures.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">ASU 2018-02 - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In February&#160;2018, the FASB issued guidance that allows an entity to reclassify the stranded tax effects resulting from the newly enacted federal corporate income tax rate from accumulated other comprehensive income (loss) to retained earnings. The guidance is effective for the Company on January&#160;1, 2019, including interim periods, with early adoption permitted. The guidance can be applied using one of two methods. One method is to record the reclassification of the stranded income taxes at the beginning of the period of adoption. The other method is to apply the guidance retrospectively to each period in which the income tax effects of the TCJA are recognized in accumulated other comprehensive income (loss). The Company early adopted the guidance on January&#160;1, 2018, and elected to reclassify the stranded income taxes at the beginning of the period. During the first quarter of 2018, the Company reclassified </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$7.9 million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> of stranded tax expense from accumulated other comprehensive loss to retained earnings. The guidance did not have a material effect on the Company's results of operations, cash flows or disclosures.</span></div><div style="line-height:120%;padding-top:14px;font-size:10pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:10pt;font-weight:bold;">Recently issued accounting standards not yet adopted</span></div><div style="line-height:120%;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">ASU 2016-02 - Leases </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In February&#160;2016, the FASB issued guidance regarding leases. The guidance requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet for operating and financing leases. The guidance remains largely the same for lessors, although some changes were made to better align lessor accounting with the new lessee accounting and to align with the revenue recognition standard. The guidance also requires additional disclosures, both quantitative and qualitative, related to operating and finance leases for the lessee and sales-type, direct financing and operating leases for the lessor. This guidance will be effective for the Company on January&#160;1, 2019, with early adoption permitted. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In July&#160;2018, the FASB issued ASU 2018-11 - </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;">Leases: Targeted Improvements,</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> an accounting standard update to ASU 2016-02. This ASU provides an entity the option to adopt the guidance using one of two modified retrospective approaches. An entity can adopt the guidance using the modified retrospective transition approach beginning in the earliest year presented in the financial statements. This method of adoption would require the restatement of prior periods reported and the presentation of lease disclosures under the new guidance for all periods reported. The additional transition method of adoption introduced by ASU 2018-11, allows entities the option to apply the guidance on the date of adoption by recognizing a cumulative effect adjustment to retained earnings during the period of adoption and does not require prior comparative periods to be restated. The Company is planning to adopt the standard on January&#160;1, 2019, utilizing the practical expedient that allows the Company to not reassess whether an expired or existing contract contains a lease, the classification of leases or initial direct costs, as well as the additional transition method of adoption applied on the date of adoption. The Company also plans to adopt a short-term leasing policy as the lessee where leases with a term of 12 months or less will not be included on the Consolidated Balance Sheet.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company formed a lease implementation team and is currently in the contract review and assessment phase to identify and evaluate contracts containing leases. Additionally, the team is implementing new and revising existing software to meet the reporting and disclosure requirements of the standard. The Company also has started to assess the impact the standard will have on its processes and internal controls and is identifying new and updating current processes. During the assessment phase, the Company is using various analytic methodologies to ensure the completeness of the lease inventory. The Company expects that most of the current operating leases will be subject to the guidance and recognized as operating lease liabilities and right-of-use assets on the Consolidated Balance Sheets upon adoption. During the fourth quarter of 2018, the Company will engage internal auditors to review and assess the completeness of the lease inventory and the effectiveness of the revised and new internal controls. The Company continues to evaluate the impact the new guidance will have on lease contracts where the Company is the lessor and, at this time, does not anticipate a significant impact. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In January&#160;2018, the FASB issued a practical expedient for land easements under the new lease guidance. The practical expedient permits an entity to elect the option to not evaluate land easements under the new guidance if they existed or expired before the adoption of the new lease guidance and were not previously accounted for as leases under the previous lease guidance. Once an entity adopts the new guidance, the entity should apply the new guidance on a prospective basis to all new or modified land easements. The Company is currently planning to adopt this practical expedient. The Company continues to monitor other </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">industry-specific issues as it relates to the regulated businesses but does not expect these issues to have a material impact on the Company's results of operations, financial position or disclosures.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">ASU 2017-04 - Simplifying the Test for Goodwill Impairment </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In January&#160;2017, the FASB issued guidance on simplifying the test for goodwill impairment by eliminating Step&#160;2, which required an entity to measure the amount of impairment loss by comparing the implied fair value of reporting unit goodwill with the carrying amount of such goodwill. This guidance requires entities to perform a quantitative impairment test, previously Step&#160;1, to identify both the existence of impairment and the amount of impairment loss by comparing the fair value of a reporting unit to its carrying amount. Entities will continue to have the option of performing a qualitative assessment to determine if the quantitative impairment test is necessary. The guidance also requires additional disclosures if an entity has one or more reporting units with zero or negative carrying amounts of net assets. The guidance will be effective for the Company on January&#160;1, 2020, and must be applied on a prospective basis with early adoption permitted. The Company is evaluating the effects the adoption of the new guidance will have on its results of operations, financial position, cash flows and disclosures.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">ASU 2018-07 - Improvements to Nonemployee Share-Based Payment Accounting </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In June&#160;2018, the FASB issued guidance on simplifying the accounting for nonemployee share-based payment transactions by expanding the scope of ASC 718, </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;">Compensation - Stock Compensation</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, to include share-based payment transactions for acquiring goods and services from nonemployees. The guidance will require nonemployee share-based payment awards be measured at the grant-date fair value of the equity instruments at the grant date. The guidance will be effective for the Company on January&#160;1, 2019, including interim periods, and must be applied using a modified retrospective approach with early adoption permitted. The modified retrospective approach requires an entity to record a cumulative-effect adjustment to retained earnings at the beginning of the year of adoption. The Company is evaluating the effects the adoption of the new guidance will have on its results of operations, financial position, cash flows and disclosures.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">ASU 2018-13 - Changes to the Disclosure Requirements for Fair Value Measurement </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In August&#160;2018, the FASB issued guidance on modifying the disclosure requirements on fair value measurements as part of the disclosure framework project. The guidance modifies, among other things, the disclosures required for Level 3 fair value measurements, including the range and weighted average of significant unobservable inputs. The guidance removes, among other things, the disclosure requirement to disclose transfers between Levels 1 and 2. The guidance will be effective for the Company on January&#160;1, 2020, including interim periods, with early adoption permitted. Level 3 fair value measurement disclosures should be applied prospectively while all other amendments should be applied retrospectively. The Company is evaluating the effects the adoption of the new guidance will have on its disclosures.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">ASU 2018-14 - Changes to the Disclosure Requirements for Defined Benefit Plans </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In August&#160;2018, the FASB issued guidance on modifying the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans as part of the disclosure framework project. The guidance removes disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The guidance adds, among other things, the requirement to include an explanation for significant gains and losses related to changes in benefit obligations for the period. The guidance removes, among other things, the disclosure requirement to disclose the amount of net periodic benefit costs to be amortized over the next fiscal year from accumulated other comprehensive income (loss) and the effects a one percentage point change in assumed health care cost trend rates will have on certain benefit components. The guidance will be effective for the Company on January&#160;1, 2021, and must be applied on a retrospective basis with early adoption permitted.

The guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract similar to the costs incurred to develop or obtain internal-use software and such capitalized costs to be expensed over the term of the hosting arrangement. Costs incurred during the preliminary and postimplementation stages should continue to be expensed as activities are performed. The capitalized costs are required to be presented on the balance sheet in the same line the prepayment for the fees associated with the hosting arrangement would be presented. In addition, the expense related to the capitalized implementation costs should be presented in the same line on the income statement as the fees associated with the hosting element of the arrangements. The guidance will be effective for the Company on January&#160;1, 2020, including interim periods, and may be applied on a retrospective or a prospective basis with early adoption permitted. The Company is evaluating the effects the adoption of the new guidance will have on the its results of operations, financial position, cash flows and disclosures.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">SEC File Number S7-15-16 - Disclosure Update and Simplification </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In October&#160;2018, the SEC published guidance in the Federal Register on disclosure updates and simplifications. The guidance removes disclosures that are no longer considered cost beneficial, duplicative of GAAP required disclosures, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The amendments are intended to facilitate disclosure of information to investors and simplify the compliance without significantly altering the total mix of information provided to investors.

<td class="text"><div style="line-height:120%;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Revenue is recognized when a performance obligation is satisfied by transferring control over a product or service to a customer. Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company is considered an agent for certain taxes collected from customers. As such, the Company presents revenues net of these taxes at the time of sale to be remitted to governmental authorities, including sales and use taxes.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The electric and natural gas distribution segments generate revenue from the sales of electric and natural gas products and services, which includes retail and transportation services. These segments establish a customer's retail or transportation service account based on the customer's application/contract for service, which indicates approval of a contract for service. The contract identifies an obligation to provide service in exchange for delivering or standing ready to deliver the identified commodity; and the customer is obligated to pay for the service as provided in the applicable tariff. The product sales are based on a fixed rate that includes a base and per-unit rate, which are included in approved tariffs as determined by state or federal regulatory agencies. The quantity of the commodity consumed or transported determines the total per-unit revenue. The service provided, along with the product consumed or transported, are a single performance obligation because both are required in combination to successfully transfer the contracted product or service to the customer. Revenues are recognized over time as customers receive and consume the products and services. The method of measuring progress toward the completion of the single performance </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">obligation is on a per-unit output method basis, with revenue recognized based on the direct measurement of the value to the customer of the goods or services transferred to date. For contracts governed by the Company&#8217;s utility tariffs, amounts are billed monthly with the amount due between 15 and 22 days of receipt of the invoice depending on the applicable state&#8217;s tariff. For other contracts not governed by tariff, payment terms are net thirty days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The pipeline and midstream segment generates revenue from providing natural gas transportation, gathering and underground storage services, as well as other energy-related services to both third parties and internal customers, largely the natural gas distribution segment. The pipeline and midstream segment establishes a contract with a customer based upon the customer&#8217;s request for firm or interruptible natural gas transportation, storage or gathering service(s). The contract identifies an obligation for the segment to provide the requested service(s) in exchange for consideration from the customer over a specified term. Depending on the type of service(s) requested and contracted, the service provided may include transporting, gathering or storing an identified quantity of natural gas and/or standing ready to deliver or store an identified quantity of natural gas. Natural gas transportation, gathering and storage revenues are based on fixed rates, which may include reservation fees and/or per-unit commodity rates. The services provided by the segment are generally treated as single performance obligations satisfied over time simultaneous to when the service is provided and revenue is recognized. Rates for the segment&#8217;s regulated services are based on its FERC approved tariff or customer negotiated rates on special projects, and rates for its non-regulated services are negotiated with its customers and set forth in the contract. For contracts governed by the company&#8217;s tariff, amounts are billed on or before the ninth business day of the following month and the amount is due within twelve days of receipt of the invoice. For gathering contracts not governed by the tariff, amounts are due within twenty days of invoice receipt. For other contracts not governed by the tariff, payment terms are net thirty days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The construction materials and contracting segment generates revenue from contracting services and construction materials sales. This segment focuses on the vertical integration of its contracting services with its construction materials to support the aggregate based product lines. This segment provides contracting services to a customer when a contract has been signed by both the customer and a representative of the segment obligating a service to be provided in exchange for the consideration identified in the contract. The nature of the services this segment provides generally includes integrating a set of services and related construction materials into a single project to create a distinct bundle of goods and services, which the Company evaluates to determine whether a separate performance obligation exists. The transaction price is the original contract price plus any subsequent change orders and variable consideration. Examples of variable consideration that exist in this segment's contracts include liquidated damages; performance bonuses or incentives and penalties; claims; unapproved/unpriced change orders; and index pricing. The variable amounts usually arise upon achievement of certain performance metrics or change in project scope. The Company estimates the amount of revenue to be recognized on variable consideration using estimation methods that best predict the most likely amount of consideration the Company expects to be entitled to or expects to incur. The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Changes in circumstances could impact management's estimates made in determining the value of variable consideration recorded. The Company updates its estimate of the transaction price each reporting period and the effect of variable consideration on the transaction price is recognized as an adjustment to revenue on a cumulative catch-up basis. Revenue is recognized over time using the input method based on the measurement of progress on a project. The input method is the preferred method of measuring revenue because the costs incurred have been determined to represent the best indication of the overall progress toward the transfer of such goods or services promised to a customer. This segment also sells construction materials to third parties and internal customers. The contract for material sales is the use of a sales order or an invoice, which includes the pricing and payment terms. All material contracts contain a single performance obligation for the delivery of a single distinct product or a distinct separately identifiable bundle of products and services. Revenue is recognized at a point in time when the performance obligation has been satisfied with the delivery of the products or services. The warranties associated with the sales are those consistent with a standard warranty that the product meets certain specifications for quality or those required by law. For most contracts, amounts billed to customers are due within thirty days of receipt. There are no material obligations for returns, refunds or other similar obligations.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The construction services segment generates revenue from specialty contracting services which also includes the sale of construction equipment and other supplies. This segment provides specialty contracting services to a customer when a contract has been signed by both the customer and a representative of the segment obligating a service to be provided in exchange for the consideration identified in the contract. The nature of the services this segment provides generally includes multiple promised goods and services in a single project to create a distinct bundle of goods and services, which the Company evaluates to determine whether a separate performance obligation exists. The transaction price is the original contract price plus any subsequent change orders and variable consideration. Examples of variable consideration that exist in this segment's contracts include claims, unapproved/unpriced change orders, bonuses, incentives, penalties and liquidated damages.

The Company believes this level of disaggregation best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. The table also includes a reconciliation of the disaggregated revenue by reportable segments.

The timing of invoicing to customers does not necessarily correlate with the timing of revenues being recognized under the cost&#8208;to&#8208;cost method of accounting. Contracts from contracting services are billed as work progresses in accordance with agreed upon contractual terms. Generally, billing to the customer occurs contemporaneous to revenue recognition. A variance in timing of the billings may result in a contract asset or a contract liability. A contract asset occurs when revenues are recognized under the cost-to-cost measure of progress, which exceeds amounts billed on uncompleted contracts. Such amounts will be billed as standard contract terms allow, usually based on various measures of performance or achievement. A contract liability occurs when there are billings in excess of revenues recognized under the cost-to-cost measure of progress on uncompleted contracts. Contract liabilities decrease as revenue is recognized from the satisfaction of the related performance obligation. The changes in contract assets and liabilities were as follows:</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><div

In June&#160;2018, the Company acquired Tri-City Paving, Inc., a general contractor and aggregate, asphalt and ready-mixed concrete supplier in Minnesota. In July&#160;2018, the Company acquired Molalla Redi-Mix and Rock Products, Inc., a producer of ready-mixed concrete in Oregon. As of September 30, 2018, the gross aggregate </span></div><div style="line-height:120%;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">consideration for these acquisitions was </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$27.9&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> in cash, subject to certain adjustments, and </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>713,948</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> shares of common stock with a market value of </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$20.1 million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> as of the respective acquisition date. Due to the holding period restriction on the common stock, the share consideration has been discounted to a fair value of approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$18.0&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, as reflected in the Company's financial statements. The acquisitions are subject to customary adjustments based on, among other things, the amount of cash, debt and working capital in the businesses as of the closing dates. The amounts included in the Consolidated Balance Sheets for these adjustments are considered provisional until final settlement has occurred.</span></div>The above acquisitions are considered business combinations and the Company has preliminarily allocated the purchase price of the acquisitions to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition dates. The excess of the purchase price over the aggregate fair values was recorded as goodwill. The Company calculated the fair value of the assets acquired using the income, market or cost approach (or a combination thereof). Fair values for some of the assets were determined based on Level 3 inputs including estimated future cash flows, discount rates, growth rates, sales projections, retention rates and terminal values, all of which require significant management judgment and are susceptible to change. The purchase price allocation is based upon preliminary information and is subject to change if additional information about the facts and circumstances that existed at the acquisition date becomes available. The final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill. However, any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations. The discount rate used in calculating the fair value of the common stock issued was determined by a Black-Scholes-Merton model. The model used Level 2 inputs including risk-free interest rate, volatility range and dividend yield. The results of the acquired businesses have been included in the Company's construction materials and contracting segment and consolidated financial statements beginning on the acquisition dates. Pro forma financial amounts reflecting the effects of the above acquisitions are not presented, as such acquisitions were not material to the Company's financial position or results of operations.<span></span>

paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The fair value ASC establishes a hierarchy for grouping assets and liabilities, based on the significance of inputs. The estimated fair values of the Company's assets and liabilities measured on a recurring basis are determined using the market approach. The Company's Level&#160;2 money market funds are valued at the net asset value of shares held at the end of the quarter, based on published market quotations on active markets, or using other known sources including pricing from outside sources. The estimated fair value of the Company's Level&#160;2 mortgage-backed securities and U.S. Treasury securities are based on comparable market transactions, other observable inputs or other sources, including pricing from outside sources. The estimated fair value of the Company's Level&#160;2 insurance contract is based on contractual cash surrender values that are determined primarily by investments in managed separate accounts of the insurer. These amounts approximate fair value. The managed separate accounts are valued based on other observable inputs or corroborated market data.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Though the Company believes the methods used to estimate fair value are consistent with those used by other market participants, the use of other methods or assumptions could result in a different estimate of fair value.

The internal reporting of these operating segments is defined based on the reporting and review process used by the Company's chief executive officer. The vast majority of the Company's operations are located within the United States.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The electric segment generates, transmits and distributes electricity in Montana, North Dakota, South Dakota and Wyoming. The natural gas distribution segment distributes natural gas in those states, as well as in Idaho, Minnesota, Oregon and Washington. These operations also supply related value-added services.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The pipeline and midstream segment provides natural gas transportation, underground storage and gathering services through regulated and nonregulated pipeline systems primarily in the Rocky Mountain and northern Great Plains regions of the United States.

This segment focuses on vertical integration of its contracting services with its construction materials to support the aggregate based product lines including aggregate placement, asphalt and concrete paving, and site development and grading. Although not common to all locations, other products include the sale of cement, liquid asphalt for various commercial and roadway applications, various finished concrete products and other building materials and related contracting services. This segment operates in the central, southern and western United States and Alaska and Hawaii.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The construction services segment provides inside and outside specialty contracting services.

Its inside services include design, construction and maintenance of electrical and communication wiring and infrastructure, fire suppression systems, and mechanical piping and services. This segment also constructs and maintains renewable energy projects. These specialty contracting services are provided to utilities and large manufacturing, commercial, industrial, institutional and government customers. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Other category includes the activities of Centennial Capital, which insures various types of risks as a captive insurer for certain of the Company's subsidiaries.

The Company files for rate adjustments to seek recovery of operating costs and capital investments, as well as reasonable returns as allowed by regulators. The Company's most recent cases by jurisdiction are discussed in the following paragraphs. The jurisdictions in which the Company provides service have requested the Company furnish plans for the effect of the reduced corporate tax rate due to the enactment of the TCJA which may impact the Company's rates. The following paragraphs include additional details and statuses of each open request.</span></div><div style="line-height:120%;padding-top:14px;font-size:10pt;"><span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;">MNPUC</span></div><div style="line-height:120%;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">On December&#160;29, 2017, the MNPUC issued a notice of investigation related to tax changes with the enactment of the TCJA. On January&#160;19, 2018, the MNPUC issued a notice of request for information, commission planning meeting and subsequent comment period. Pursuant to the notice, Great Plains provided preliminary impacts of the TCJA on January&#160;30, 2018.

On August 9, 2018, the MNPUC ruled that Great Plains reduce rates to reflect TCJA impacts and to also provide a one-time refund that captures the TCJA impacts from January 1, 2018 through the implementation date of new rates. To date, an order by the MNPUC has not been issued.

On April&#160;2, 2018, Montana-Dakota submitted its plan requesting the MTPSC recognize the identified need for additional rate relief and to consider the effects of the TCJA in a general electric rate case to be submitted by September&#160;30, 2018. Montana-Dakota submitted the general electric rate case on September 28, 2018, as discussed below. A hearing is scheduled for December 4, 2018.

The requested increase is primarily to recover investments in facilities to enhance safety and reliability and the depreciation and taxes associated with the increase in investment. The increase was offset by tax savings related to the TCJA. Montana-Dakota requested an interim increase of approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$4.6&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> or approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>7.3</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> percent, subject to refund.

The requested increase is primarily to recover the increased investment in distribution facilities to enhance system safety and reliability and the depreciation and taxes associated with the increase in investment. Montana-Dakota also introduced a SSIP and the proposed adjustment mechanism required to fund the SSIP. Montana-Dakota requested an interim increase of approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$4.6&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> or approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>4.2</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">&#160;percent, subject to refund. On September&#160;6, 2017, the NDPSC approved the request for interim rates effective with service rendered on or after September&#160;19, 2017. On February&#160;14, 2018, Montana-Dakota filed a revised interim increase request of approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$2.7&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, subject to refund, incorporating the estimated impacts of the TCJA reduction in the federal corporate income tax rate. On March&#160;1, 2018, the updated interim rates were implemented. The impact of the TCJA was submitted as part of a rebuttal testimony identifying a reduction of the adjusted revenue requirement to approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$3.6&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. A hearing was held May&#160;30, 2018 through June&#160;1, 2018. On July&#160;19, 2018, a settlement was filed reflecting a revised annual revenue increase of approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$2.5&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> or approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>2.3</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">&#160;percent. The proposed adjustment mechanism to fund the SSIP was not included in the settlement and will be decided on separately by the NDPSC. On September&#160;26, 2018, the NDPSC issued an order approving the settlement as filed but did not approve the SSIP recovery mechanism. On October 5, 2018, Montana-Dakota submitted a compliance filing, which included a refund plan for the interim amount to be refunded to customers. This matter is pending before the NDPSC.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">On January&#160;10, 2018, the NDPSC issued a general order initiating the investigation into the effects of the TCJA. The order required regulatory deferral accounting on the impacts of the TCJA and for companies to file comments and the expected impacts. On February&#160;15, 2018, Montana-Dakota filed a summary of the primary impacts of the TCJA on the electric and natural gas utilities. On March&#160;9, 2018, Montana-Dakota submitted a request to decrease its electric rates by </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$7.2&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> or </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>3.9</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">&#160;percent annually.

On September&#160;26, 2018, the NDPSC issued an order approving the settlement along with requiring an additional adjustment to the rates to return 100&#160;percent of the tax-effective 2018 excess deferred income taxes.

The order required Montana-Dakota to provide comments by February&#160;1, 2018, regarding the general effects of the TCJA on the cost of service in South Dakota and possible mechanisms for adjusting rates. The order also stated that all rates impacted by the federal income tax shall be adjusted effective January&#160;1, 2018, subject to refund. On May&#160;4, 2018 and June&#160;2, 2018, Montana-Dakota submitted detailed plans to address the TCJA impacts on the natural gas and electric utilities, respectively, to the SDPUC staff. On September 28, 2018, a settlement agreement was submitted to the SDPUC reflecting a proposal to refund approximately</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$600,000</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> to electric customers and approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$1.3&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> to natural gas customers.

Proposed rate changes to reflect 2018 pro forma results and the TCJA impacts will be submitted by December 1, 2018. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"><span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;">WUTC</span></div><div style="line-height:120%;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">On August&#160;31, 2017, Cascade filed an application with the WUTC for a natural gas rate increase of approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$5.9&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> annually or approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>2.7</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">&#160;percent above current rates. The requested increase includes costs associated with increased infrastructure investment and the associated operating expenses. Also included in the request is recovery of operation and maintenance costs associated with a maximum allowable operating pressure validation plan. On January&#160;3, 2018, the WUTC filed a bench request requiring Cascade to provide information related to the impacts of the TCJA on Cascade's revenue requirement and a proposed ratemaking treatment of those impacts. On March&#160;23, 2018, Cascade filed its rebuttal testimony revising the revenue requirement to a decrease of approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$1.7&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> annually, which includes the impacts of the TCJA. On May&#160;17, 2018, Cascade, the WUTC staff and interveners in the case reached a settlement on all matters in the rate case except the treatment of interim tax benefits for the period January&#160;1, 2018 through July&#160;31, 2018. The settlement included an overall annual rate reduction of approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$2.9&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> or approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>1.4</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">&#160;percent plus specific tariffs passing excess deferred income taxes back to customers totaling approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$2.5&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. On July&#160;20, 2018, the WUTC approved the settlement reflecting a decrease in annual revenues, as well as refunding an additional </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$1.6&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> for the interim tax benefits for the period of January&#160;1, 2018 through July&#160;31, 2018. The refund of excess deferred income taxes and interim tax benefits is over a fifteen month period. These changes were effective August&#160;1, 2018.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">On June 1, 2018, Cascade filed its annual pipeline cost recovery mechanism requesting an increase in annual revenue of </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$2.3&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> or approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>1.1</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">&#160;percent. On October 11&#160;2018, Cascade filed a revised increase in annual revenue of </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$2.1&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> or approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>1.0</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">&#160;percent. The increase will go into effect on November&#160;1, 2018. </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"><span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;">WYPSC</span></div><div style="line-height:120%;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">On December&#160;29, 2017, the WYPSC issued a general order requiring regulatory deferral accounting on the impacts of the TCJA. A technical conference was held on February&#160;6, 2018, to discuss the implications of the TCJA. On March&#160;23, 2018, the WYPSC issued an order requiring all public utilities to submit an initial assessment of the overall effects on the TCJA on their rates by March&#160;30, 2018. On March&#160;30, 2018, Montana-Dakota submitted its initial assessment indicating a rate reduction for its electric rates in the amount of approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$1.1&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> annually or approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>4.2</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">&#160;percent. Revised electric rates reflecting this reduction were submitted to the WYPSC on June&#160;13, 2018. Montana-Dakota reported its natural gas earnings do not support a decrease in rates and requested the WYPSC allow the impacts of the TCJA be addressed in a natural gas rate case to be submitted by June&#160;1, 2019. Both matters are pending before the WYPSC.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"><span style="font-family:Trade Gothic Bold 2,sans-serif;font-size:10pt;">FERC</span></div><div style="line-height:120%;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Montana-Dakota and certain MISO Transmission Owners with projected rates submitted a filing to the FERC on February&#160;1, 2018, requesting the FERC to waive certain provisions of the MISO tariff in order for Montana-Dakota and certain MISO Transmission Owners with projected rates to revise their rates to reflect the reduction in the corporate tax rate. Under the MISO tariff, rates are to be changed only on an annual basis with any changes reflected in subsequent true-ups. On March&#160;15, 2018, the FERC approved the waiver request and new rates reflecting the effects of the TCJA were implemented by MISO on March&#160;1, 2018. MISO also retroactively re-billed the January and February 2018 services to reflect the new rates. On September 4, 2018, Montana-Dakota filed an update to its transmission formula rate under the MISO tariff for the multivalue project for </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$12.5&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, which is effective January 1, 2019.</span></div>On July&#160;18, 2018, the FERC issued a final rule on Rate Changes Relating to Federal Income Tax Rate reductions resulting from the TCJA which requires natural gas pipeline companies to make a one-time informational filing to evaluate the impact of the lower corporate income tax rate and also select one of four options presented by the FERC to address the impact. In accordance with WBI Energy Transmission&#8217;s offer of settlement and stipulation and agreement with the FERC dated June&#160;4, 2014, the Company is to make a filing with new proposed rates to be effective no later than May&#160;1, 2019. On October 31, 2018, the Company filed a rate case with the FERC with rates effective May 1, 2019. Due to the timing of the rate case filing, the Company will be exempt from the one-time informational filing required by the FERC&#8217;s final rule.<span></span>

The Company accrues a liability for those contingencies when the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Company does not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is probable or reasonably possible and which are material, the Company discloses the nature of the contingency and, in some circumstances, an estimate of the possible loss. Accruals are based on the best information available, but in certain situations management is unable to estimate an amount or range of a reasonably possible loss including, but not limited to when: (1) the damages are unsubstantiated or indeterminate, (2) the proceedings are in the early stages, (3) numerous parties are involved, or (4) the matter involves novel or unsettled legal theories. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company accrued liabilities of </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$30.4&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$34.3&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> and </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$35.4&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, which have not been discounted, including liabilities held for sale, for contingencies, including litigation, production taxes, royalty claims and environmental matters at </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">September&#160;30, 2018</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> and </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">2017</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, and </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">December&#160;31, 2017</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, respectively. This includes amounts that have been accrued for matters discussed in Environmental matters within this note. The Company will continue to monitor each matter and adjust accruals as might be warranted based on new information and further developments. Management believes that the outcomes with respect to probable and reasonably possible losses in excess of the amounts accrued, net of insurance recoveries, while uncertain, either cannot be estimated or will not have a material effect upon the Company's financial position, results of operations or cash flows. Unless otherwise required by GAAP, legal costs are expensed as they are incurred.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:10pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:10pt;font-weight:bold;">Environmental matters</span></div><div style="line-height:120%;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">Portland Harbor Site </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In December 2000, Knife River&#160;- Northwest was named by the EPA as a PRP in connection with the cleanup of a riverbed site adjacent to a commercial property site acquired by Knife River&#160;- Northwest from Georgia-Pacific West, Inc. in 1999. The riverbed site is part of the Portland, Oregon, Harbor Superfund Site. The EPA wants responsible parties to share in the cleanup of sediment contamination in the Willamette River. To date, costs of the overall remedial investigation and feasibility study of the harbor site are being recorded, and initially paid, through an administrative consent order by the LWG, a group of several entities, which does not include Knife River&#160;- Northwest or Georgia-Pacific West, Inc. Investigative costs are indicated to be in excess of </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$100&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. On January&#160;6, 2017, Region&#160;10 of the EPA issued an ROD with its selected remedy for cleanup of the in-river portion of the site. Implementation of the remedy is expected to take up to 13&#160;years with a present value cost estimate of approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$1&#160;billion</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. Corrective action will not be taken until remedial design/remedial action plans are approved by the EPA. Knife River&#160;- Northwest also received notice in January 2008 that the Portland Harbor Natural Resource Trustee Council intends to perform an injury assessment to natural resources resulting from the release of hazardous substances at the Harbor Superfund Site. The Portland Harbor Natural Resource Trustee Council indicates the injury determination is appropriate to facilitate early settlement of damages and restoration for natural resource injuries. It is not possible to estimate the costs of natural resource damages until an assessment is completed and allocations are undertaken.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Based upon a review of the Portland Harbor sediment contamination evaluation by the Oregon DEQ and other information available, Knife River&#160;- Northwest does not believe it is a responsible party. In addition, Knife River&#160;- Northwest has notified Georgia-Pacific West, Inc., that it intends to seek indemnity for liabilities incurred in relation to the above matters pursuant to the terms of their sale agreement. Knife River&#160;- Northwest has entered into an agreement tolling the statute of limitations in connection with the LWG's potential claim for contribution to the costs of the remedial investigation and feasibility study. By letter in March 2009, LWG stated its intent to file suit against Knife River&#160;- Northwest and others to recover LWG's investigation costs to the extent Knife River&#160;- Northwest cannot demonstrate its non-liability for the contamination or is unwilling to participate in an alternative dispute resolution process that has been established to address the matter. At this time, Knife River&#160;- Northwest has agreed to participate in the alternative dispute resolution process.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company believes it is not probable that it will incur any material environmental remediation costs or damages in relation to the above referenced matter.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">Manufactured Gas Plant Sites </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">There are three claims against Cascade for cleanup of environmental contamination at manufactured gas plant sites operated by Cascade's predecessors. The accruals related to these claims are reflected in regulatory assets.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The first claim is for contamination at a site in Eugene, Oregon which was received in 1995. The Oregon DEQ released an ROD in January 2015 that selected a remediation alternative for the site as recommended in an earlier staff report. The total estimated cost for the selected remediation, including long-term maintenance, is approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$3.5&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> of which </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$400,000</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> has been incurred. Cascade and other PRPs will share in the cleanup costs with Cascade expecting to pay approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>50</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">&#160;percent of the remediation and maintenance costs. Cascade has an accrual balance of </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$1.6&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> for remediation of this site. In January 2013, the OPUC approved Cascade's application to defer environmental remediation costs at the Eugene site for a period of 12&#160;months starting November&#160;30, 2012. Cascade received orders reauthorizing the deferred accounting for the 12-month periods starting November&#160;30, 2013, December&#160;1, 2014, December&#160;1, 2015, December&#160;1, 2016 and December&#160;1, 2017.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The second claim is for contamination at the Bremerton Gasworks Superfund Site in Bremerton, Washington which was received in 1997. A preliminary investigation has found soil and groundwater at the site contain contaminants requiring further investigation and cleanup. The EPA conducted a Targeted Brownfields Assessment of the site and released a report summarizing the results of that assessment in August 2009. The assessment confirms that contaminants have affected soil and groundwater at the site, as well as sediments in the adjacent Port Washington Narrows. Alternative remediation options have been identified with preliminary cost estimates ranging from </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$340,000</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> to </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$6.4&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. Data developed through the assessment and previous investigations indicates the contamination likely derived from multiple, different sources and multiple current and former owners of properties and businesses in the vicinity of the site may be responsible for the contamination. In April 2010, the Washington DOE issued notice it considered Cascade a PRP for hazardous substances at the site. In May 2012, the EPA added the site to the National Priorities List of Superfund sites. Cascade has entered into an administrative settlement agreement and consent order with the EPA regarding the scope and schedule for a remedial investigation and feasibility study for the site. Current estimates for the cost to complete the remedial investigation and feasibility study are approximately </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$7.6&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> of which </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$2.7&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> has been incurred. Cascade has accrued </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$4.9&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> for the remedial investigation and feasibility study, as well as </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$6.4&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> for remediation of this site; however, the accrual for remediation costs will be reviewed and adjusted, if necessary, after completion of the remedial investigation and feasibility study. In April 2010, Cascade filed a petition with the WUTC for authority to defer the </span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">costs incurred in relation to the environmental remediation of this site. The WUTC approved the petition in September 2010, subject to conditions set forth in the order.</span></div><div style="line-height:120%;padding-top:14px;text-align:left;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The third claim is for contamination at a site in Bellingham, Washington. Cascade received notice from a party in May 2008 that Cascade may be a PRP, along with other parties, for contamination from a manufactured gas plant owned by Cascade and its predecessor from about 1946 to 1962. Other PRPs reached an agreed order and work plan with the Washington DOE for completion of a remedial investigation and feasibility study for the site. A feasibility study prepared for one of the PRPs in March 2018 identifies five cleanup action alternatives for the site with estimated costs ranging from </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$8.0&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> to </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$20.4&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> with a selected preferred alternative having an estimated total cost of </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$9.3&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. Cascade believes its proportional share of any liability will be relatively small in comparison to other PRPs. The plant manufactured gas from coal between approximately 1890 and 1946. In 1946, shortly after Cascade's predecessor acquired the plant, it converted the plant to a propane-air gas facility.

Tesoro agreed to indemnify Centennial for any losses and litigation expenses arising from the guarantee. The estimated fair value of the indemnity asset is reflected in deferred charges and other assets - other and the guarantee liability is reflected in other accrued liabilities and deferred credits and other liabilities - other, on the Consolidated Balance Sheets. Continuation of the guarantee was required as a condition to the sale of Dakota Prairie Refining.

The Coyote Station owners are also providing a guarantee of the value of the assets of Coyote Creek as they would be required to buy the assets at book value should they terminate the contract prior to the end of the contract term and are providing a guarantee of the value of the equity of Coyote Creek in that they are required to buy the entity at the end of the contract term at equity value. Although the Company has determined that Coyote Creek is a VIE, the Company has concluded that it is not the primary beneficiary of Coyote Creek because the authority to direct the activities of the entity is shared by the four unrelated owners of the Coyote Station, with no primary beneficiary existing. As a result, Coyote Creek is not required to be consolidated in the Company's financial statements.</span></div><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">At </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">September&#160;30, 2018</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, the Company's exposure to loss as a result of the Company's involvement with the VIE, based on the Company's ownership percentage, was </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$39.2&#160;million</span></span>.<span></span>

The guidance provides for a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry specific guidance. In August&#160;2015, the FASB issued guidance deferring the effective date of the revenue guidance and allowing entities to </span></div><div style="line-height:120%;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">early adopt. With this decision, the guidance was effective for the Company on January&#160;1, 2018. Entities had the option of using either a full retrospective or modified retrospective approach to adopting the guidance. Under the modified retrospective approach, an entity recognizes the cumulative effect of initially applying the guidance with an adjustment to the opening balance of retained earnings in the period of adoption. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company adopted the guidance on January&#160;1, 2018, using the modified retrospective approach. The Company elected the practical expedient to not disclose the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied (or partially unsatisfied) as of the end of the reporting period, along with an explanation of when such revenue would be expected to be recognized. This practical expedient was used since the performance obligations are part of contracts with an original duration of one year or less. The Company also elected the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company otherwise would have recognized is one year or less. Upon completion of the Company's evaluation of contracts and methods of revenue recognition under the previous accounting guidance, the Company did not identify any material cumulative effect adjustments to be made to retained earnings. In addition, the Company has expanded revenue disclosures, both quantitatively and qualitatively, related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, as discussed in Note&#160;</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">8</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">. The Company reviewed its revenue streams to evaluate the impact of this guidance and did not identify a significant change in the timing of revenue recognition, results of operations, financial position or cash flows. The Company reviewed its internal controls related to revenue recognition and disclosures and concluded that the guidance impacted certain business processes and controls. As such, the Company developed modifications to its internal controls for certain topics under the guidance as they apply to the Company and such modifications were not deemed to be significant. Results for reporting periods beginning after December&#160;31, 2017, are presented under the new guidance, while prior period amounts are not adjusted and continue to be reported in accordance with historic accounting for revenue recognition.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">Under the modified retrospective approach, the guidance was applied only to contracts that were not completed as of January&#160;1, 2018. Therefore, the Company recognized the cumulative effect of initially applying the guidance with an adjustment to the opening balance of retained earnings at January&#160;1, 2018. For the nine months ended September&#160;30, </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">2018</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, there were </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>no</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> material impacts to the financial statements as a result of applying the guidance.

The guidance is intended to standardize the presentation and classification of certain transactions, including cash payments for debt prepayment or extinguishment, proceeds from insurance claim settlements and distributions from equity method investments. In addition, the guidance clarifies how to classify transactions that have characteristics of more than one class of cash flows.

The guidance provides a screen to determine when an integrated set of assets and activities is not a business. The guidance also affects other aspects of accounting, such as determining reporting units for goodwill testing and whether an entity has acquired or sold a business. The Company adopted the guidance on January&#160;1, 2018, on a prospective basis. The guidance did not have a material effect on the Company's results of operations, financial position, cash flows or disclosures.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">ASU 2017-07 - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In March&#160;2017, the FASB issued guidance to improve the presentation of net periodic pension and net periodic postretirement benefit costs. The guidance required the service cost component to be presented in the income statement in the same line item or items as other compensation costs arising from services performed during the period. Other components of net periodic benefit cost shall be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. The guidance also only allows the service cost component to be capitalized.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company adopted the guidance on January&#160;1, 2018, on a retrospective basis. The guidance required the reclassification of all components of net periodic benefit costs, except for the service cost component, from operating expenses to other income on the Consolidated Statements of Income with no impact to earnings. As a result of the retrospective application of this change in accounting guidance, the Company reclassified </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$1.5 million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> and </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$4.5&#160;million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> from operation and maintenance expense to other income on the Consolidated Statements of Income for the </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">three and nine</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> months ended September&#160;30, 2017, respectively.

The guidance is effective for the Company on January&#160;1, 2019, including interim periods, with early adoption permitted. The guidance can be applied using one of two methods. One method is to record the reclassification of the stranded income taxes at the beginning of the period of adoption. The other method is to apply the guidance retrospectively to each period in which the income tax effects of the TCJA are recognized in accumulated other comprehensive income (loss). The Company early adopted the guidance on January&#160;1, 2018, and elected to reclassify the stranded income taxes at the beginning of the period. During the first quarter of 2018, the Company reclassified </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"><span>$7.9 million</span></span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> of stranded tax expense from accumulated other comprehensive loss to retained earnings.

The guidance requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet for operating and financing leases. The guidance remains largely the same for lessors, although some changes were made to better align lessor accounting with the new lessee accounting and to align with the revenue recognition standard. The guidance also requires additional disclosures, both quantitative and qualitative, related to operating and finance leases for the lessee and sales-type, direct financing and operating leases for the lessor. This guidance will be effective for the Company on January&#160;1, 2019, with early adoption permitted. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In July&#160;2018, the FASB issued ASU 2018-11 - </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;">Leases: Targeted Improvements,</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;"> an accounting standard update to ASU 2016-02. This ASU provides an entity the option to adopt the guidance using one of two modified retrospective approaches. An entity can adopt the guidance using the modified retrospective transition approach beginning in the earliest year presented in the financial statements. This method of adoption would require the restatement of prior periods reported and the presentation of lease disclosures under the new guidance for all periods reported. The additional transition method of adoption introduced by ASU 2018-11, allows entities the option to apply the guidance on the date of adoption by recognizing a cumulative effect adjustment to retained earnings during the period of adoption and does not require prior comparative periods to be restated. The Company is planning to adopt the standard on January&#160;1, 2019, utilizing the practical expedient that allows the Company to not reassess whether an expired or existing contract contains a lease, the classification of leases or initial direct costs, as well as the additional transition method of adoption applied on the date of adoption. The Company also plans to adopt a short-term leasing policy as the lessee where leases with a term of 12 months or less will not be included on the Consolidated Balance Sheet.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The Company formed a lease implementation team and is currently in the contract review and assessment phase to identify and evaluate contracts containing leases. Additionally, the team is implementing new and revising existing software to meet the reporting and disclosure requirements of the standard. The Company also has started to assess the impact the standard will have on its processes and internal controls and is identifying new and updating current processes. During the assessment phase, the Company is using various analytic methodologies to ensure the completeness of the lease inventory. The Company expects that most of the current operating leases will be subject to the guidance and recognized as operating lease liabilities and right-of-use assets on the Consolidated Balance Sheets upon adoption. During the fourth quarter of 2018, the Company will engage internal auditors to review and assess the completeness of the lease inventory and the effectiveness of the revised and new internal controls. The Company continues to evaluate the impact the new guidance will have on lease contracts where the Company is the lessor and, at this time, does not anticipate a significant impact. </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In January&#160;2018, the FASB issued a practical expedient for land easements under the new lease guidance. The practical expedient permits an entity to elect the option to not evaluate land easements under the new guidance if they existed or expired before the adoption of the new lease guidance and were not previously accounted for as leases under the previous lease guidance. Once an entity adopts the new guidance, the entity should apply the new guidance on a prospective basis to all new or modified land easements.

This guidance requires entities to perform a quantitative impairment test, previously Step&#160;1, to identify both the existence of impairment and the amount of impairment loss by comparing the fair value of a reporting unit to its carrying amount. Entities will continue to have the option of performing a qualitative assessment to determine if the quantitative impairment test is necessary. The guidance also requires additional disclosures if an entity has one or more reporting units with zero or negative carrying amounts of net assets. The guidance will be effective for the Company on January&#160;1, 2020, and must be applied on a prospective basis with early adoption permitted. The Company is evaluating the effects the adoption of the new guidance will have on its results of operations, financial position, cash flows and disclosures.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;font-weight:bold;">ASU 2018-07 - Improvements to Nonemployee Share-Based Payment Accounting </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">In June&#160;2018, the FASB issued guidance on simplifying the accounting for nonemployee share-based payment transactions by expanding the scope of ASC 718, </span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;font-style:italic;">Compensation - Stock Compensation</span><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">, to include share-based payment transactions for acquiring goods and services from nonemployees. The guidance will require nonemployee share-based payment awards be measured at the grant-date fair value of the equity instruments at the grant date. The guidance will be effective for the Company on January&#160;1, 2019, including interim periods, and must be applied using a modified retrospective approach with early adoption permitted. The modified retrospective approach requires an entity to record a cumulative-effect adjustment to retained earnings at the beginning of the year of adoption.

The guidance modifies, among other things, the disclosures required for Level 3 fair value measurements, including the range and weighted average of significant unobservable inputs. The guidance removes, among other things, the disclosure requirement to disclose transfers between Levels 1 and 2. The guidance will be effective for the Company on January&#160;1, 2020, including interim periods, with early adoption permitted. Level 3 fair value measurement disclosures should be applied prospectively while all other amendments should be applied retrospectively.

The guidance removes disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The guidance adds, among other things, the requirement to include an explanation for significant gains and losses related to changes in benefit obligations for the period. The guidance removes, among other things, the disclosure requirement to disclose the amount of net periodic benefit costs to be amortized over the next fiscal year from accumulated other comprehensive income (loss) and the effects a one percentage point change in assumed health care cost trend rates will have on certain benefit components. The guidance will be effective for the Company on January&#160;1, 2021, and must be applied on a retrospective basis with early adoption permitted.

The guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract similar to the costs incurred to develop or obtain internal-use software and such capitalized costs to be expensed over the term of the hosting arrangement. Costs incurred during the preliminary and postimplementation stages should continue to be expensed as activities are performed. The capitalized costs are required to be presented on the balance sheet in the same line the prepayment for the fees associated with the hosting arrangement would be presented. In addition, the expense related to the capitalized implementation costs should be presented in the same line on the income statement as the fees associated with the hosting element of the arrangements. The guidance will be effective for the Company on January&#160;1, 2020, including interim periods, and may be applied on a retrospective or a prospective basis with early adoption permitted.

The guidance removes disclosures that are no longer considered cost beneficial, duplicative of GAAP required disclosures, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The amendments are intended to facilitate disclosure of information to investors and simplify the compliance without significantly altering the total mix of information provided to investors.

<td class="text">Revenue is recognized when a performance obligation is satisfied by transferring control over a product or service to a customer. Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company is considered an agent for certain taxes collected from customers. As such, the Company presents revenues net of these taxes at the time of sale to be remitted to governmental authorities, including sales and use taxes.<div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The electric and natural gas distribution segments generate revenue from the sales of electric and natural gas products and services, which includes retail and transportation services. These segments establish a customer's retail or transportation service account based on the customer's application/contract for service, which indicates approval of a contract for service. The contract identifies an obligation to provide service in exchange for delivering or standing ready to deliver the identified commodity; and the customer is obligated to pay for the service as provided in the applicable tariff. The product sales are based on a fixed rate that includes a base and per-unit rate, which are included in approved tariffs as determined by state or federal regulatory agencies. The quantity of the commodity consumed or transported determines the total per-unit revenue. The service provided, along with the product consumed or transported, are a single performance obligation because both are required in combination to successfully transfer the contracted product or service to the customer. Revenues are recognized over time as customers receive and consume the products and services. The method of measuring progress toward the completion of the single performance </span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">obligation is on a per-unit output method basis, with revenue recognized based on the direct measurement of the value to the customer of the goods or services transferred to date. For contracts governed by the Company&#8217;s utility tariffs, amounts are billed monthly with the amount due between 15 and 22 days of receipt of the invoice depending on the applicable state&#8217;s tariff. For other contracts not governed by tariff, payment terms are net thirty days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The pipeline and midstream segment generates revenue from providing natural gas transportation, gathering and underground storage services, as well as other energy-related services to both third parties and internal customers, largely the natural gas distribution segment. The pipeline and midstream segment establishes a contract with a customer based upon the customer&#8217;s request for firm or interruptible natural gas transportation, storage or gathering service(s). The contract identifies an obligation for the segment to provide the requested service(s) in exchange for consideration from the customer over a specified term. Depending on the type of service(s) requested and contracted, the service provided may include transporting, gathering or storing an identified quantity of natural gas and/or standing ready to deliver or store an identified quantity of natural gas. Natural gas transportation, gathering and storage revenues are based on fixed rates, which may include reservation fees and/or per-unit commodity rates. The services provided by the segment are generally treated as single performance obligations satisfied over time simultaneous to when the service is provided and revenue is recognized. Rates for the segment&#8217;s regulated services are based on its FERC approved tariff or customer negotiated rates on special projects, and rates for its non-regulated services are negotiated with its customers and set forth in the contract. For contracts governed by the company&#8217;s tariff, amounts are billed on or before the ninth business day of the following month and the amount is due within twelve days of receipt of the invoice. For gathering contracts not governed by the tariff, amounts are due within twenty days of invoice receipt. For other contracts not governed by the tariff, payment terms are net thirty days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The construction materials and contracting segment generates revenue from contracting services and construction materials sales. This segment focuses on the vertical integration of its contracting services with its construction materials to support the aggregate based product lines. This segment provides contracting services to a customer when a contract has been signed by both the customer and a representative of the segment obligating a service to be provided in exchange for the consideration identified in the contract. The nature of the services this segment provides generally includes integrating a set of services and related construction materials into a single project to create a distinct bundle of goods and services, which the Company evaluates to determine whether a separate performance obligation exists. The transaction price is the original contract price plus any subsequent change orders and variable consideration. Examples of variable consideration that exist in this segment's contracts include liquidated damages; performance bonuses or incentives and penalties; claims; unapproved/unpriced change orders; and index pricing. The variable amounts usually arise upon achievement of certain performance metrics or change in project scope. The Company estimates the amount of revenue to be recognized on variable consideration using estimation methods that best predict the most likely amount of consideration the Company expects to be entitled to or expects to incur. The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Changes in circumstances could impact management's estimates made in determining the value of variable consideration recorded. The Company updates its estimate of the transaction price each reporting period and the effect of variable consideration on the transaction price is recognized as an adjustment to revenue on a cumulative catch-up basis. Revenue is recognized over time using the input method based on the measurement of progress on a project. The input method is the preferred method of measuring revenue because the costs incurred have been determined to represent the best indication of the overall progress toward the transfer of such goods or services promised to a customer. This segment also sells construction materials to third parties and internal customers. The contract for material sales is the use of a sales order or an invoice, which includes the pricing and payment terms. All material contracts contain a single performance obligation for the delivery of a single distinct product or a distinct separately identifiable bundle of products and services. Revenue is recognized at a point in time when the performance obligation has been satisfied with the delivery of the products or services. The warranties associated with the sales are those consistent with a standard warranty that the product meets certain specifications for quality or those required by law. For most contracts, amounts billed to customers are due within thirty days of receipt. There are no material obligations for returns, refunds or other similar obligations.</span></div><div style="line-height:120%;padding-top:14px;font-size:9pt;"><span style="font-family:Trade Gothic,sans-serif;font-size:9pt;">The construction services segment generates revenue from specialty contracting services which also includes the sale of construction equipment and other supplies. This segment provides specialty contracting services to a customer when a contract has been signed by both the customer and a representative of the segment obligating a service to be provided in exchange for the consideration identified in the contract. The nature of the services this segment provides generally includes multiple promised goods and services in a single project to create a distinct bundle of goods and services, which the Company evaluates to determine whether a separate performance obligation exists. The transaction price is the original contract price plus any subsequent change orders and variable consideration. Examples of variable consideration that exist in this segment's contracts include claims, unapproved/unpriced change orders, bonuses, incentives, penalties and liquidated damages.

The Company accrues a liability for those contingencies when the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Company does not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is probable or reasonably possible and which are material, the Company discloses the nature of the contingency and, in some circumstances, an estimate of the possible loss. Accruals are based on the best information available, but in certain situations management is unable to estimate an amount or range of a reasonably possible loss including, but not limited to when: (1) the damages are unsubstantiated or indeterminate, (2) the proceedings are in the early stages, (3) numerous parties are involved, or (4) the matter involves novel or unsettled legal theories.<span></span>
