Additionally, the average customer consumption has tended to decline due to increases in energy efficient lighting and appliances being installed. The interconnected system consists of 15&#160;electric generating units at 10 facilities and two small portable diesel generators, which have an aggregate nameplate rating attributable to Montana-Dakota's interest of 750,318&#160;kW and total net ZRCs of 512.3 in 2020. For 2020, Montana-Dakota's total ZRCs, including its firm purchase power contracts, were 553.2. Montana-Dakota's planning reserve margin requirement within MISO was 531.4 ZRCs for 2020. The maximum electric peak demand experienced to date attributable to Montana-Dakota's sales to retail customers on the interconnected system was 611,542&#160;kW in August 2015.

Each of these permits has a five-year life. Near the expiration of these permits, renewal applications are submitted. Permits continue in force beyond the expiration date, provided the application for renewal is submitted by the required date, usually six months prior to expiration. The Title&#160;V Operating Permit renewal application for Coyote Station was submitted timely to the North Dakota Department of Health in September 2017, and the permit was issued on May 27, 2020. Wygen&#160;III is allowed to operate under the facility's construction permit until the Title&#160;V Operating Permit is issued by the Wyoming Department of Environmental Quality. The Title&#160;V Operating Permit application for Wygen&#160;III was submitted timely in January 2011, with the permit issuance date not specified at this time. The Title&#160;V Operating Permit renewal application for Heskett Station was submitted timely in June 2019 to the NDDEQ and the permit was issued on February 4, 2020.

Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> The natural gas distribution operations serve retail natural gas markets, consisting principally of residential and firm commercial space and water heating users, in portions of Idaho, Minnesota, Montana, North Dakota, Oregon, South Dakota, Washington and Wyoming. These markets are highly seasonal and sales volumes depend largely on the weather, the effects of which are mitigated in certain jurisdictions by weather normalization mechanisms discussed later in Regulatory Matters. Additionally, the average customer consumption has tended to decline as more efficient appliances and furnaces are installed and as the Company has implemented conservation programs. In addition to the residential and commercial sales, the utilities transport natural gas for larger commercial and industrial customers who purchase their own supply of natural gas. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Competition resulting from customer demands, technological advances and other factors exists between natural gas and other fuels and forms of energy. The natural gas distribution operations have established various natural gas transportation service rates for their distribution businesses to retain interruptible commercial and industrial loads. These rates have enhanced the natural gas distribution operations' competitive posture with alternative fuels, although certain customers have bypassed the distribution systems by directly accessing transmission pipelines within close proximity. These bypasses do not have a material effect on results of operations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The natural gas distribution operations and various distribution transportation customers obtain natural gas for their system requirements directly from producers, processors and marketers. The Company's purchased natural gas is supplied by a portfolio of contracts specifying market-based pricing and is transported under transportation agreements with WBI Energy Transmission, Northern Border Pipeline Company, Northwest Pipeline LLC, South Dakota Intrastate Pipeline, Northern Natural Gas, Gas Transmission Northwest LLC, Northwestern Energy, Viking Gas Transmission Company, Enbridge Westcoast Pipeline, Inc., Ruby Pipeline LLC, Foothills Pipe Lines Ltd., NOVA Gas Transmission Ltd, TC Energy Corporation and Northwest Natural. The natural gas distribution operations have contracts for storage services to provide gas supply during the winter heating season and to meet peak day demand with various storage providers, including WBI Energy Transmission, Dominion Energy Questar Pipeline, LLC, Northwest Pipeline LLC, Northwest Natural and Northern Natural Gas. In addition, certain of the operations have entered into natural gas supply management agreements with various parties. Demand for natural gas, which is a widely traded commodity, has historically been sensitive to seasonal heating and industrial load requirements, as well as changes in market price. The Company believes supplies are adequate for the natural gas distribution operations to meet its system natural gas requirements for the next decade. This belief is based on current and projected domestic and regional supplies of natural gas and the pipeline transmission network currently available through its suppliers and pipeline service providers.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:8pt;font-weight:700;line-height:140%">Regulatory Matters</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:700;line-height:140%"> </span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The natural gas distribution operations' retail natural gas rate schedules contain clauses permitting adjustments in rates based upon changes in natural gas commodity, transportation and storage costs.

PCB storage areas are registered with the EPA as required. Capital and operational expenditures for natural gas distribution operations could be affected in a variety of ways by potential new GHG legislation or regulation. In particular, such legislation or regulation would likely increase capital expenditures for energy efficiency and conservation programs and operational costs associated with GHG emissions compliance.

The number and size of competitors varies in each of Knife River's principal market areas and product lines.</span></div><div style="height:54pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:700;line-height:120%">16   MDU Resources Group, Inc.</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:400;line-height:120%"> Form 10-K</span></div><div style="margin-top:11pt"><span><br/></span></div></div></div><hr style="page-break-after:always"/><div style="min-height:54pt;width:100%"><div style="text-align:right"><span><br/></span></div><div style="text-align:right"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:12pt;font-weight:700;line-height:120%">Part I</span></div><div><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The demand for construction materials products and contracting services is significantly influenced by the cyclical nature of the construction industry. In addition, activity in certain locations may be seasonal in nature due to the effects of weather. The key economic factors affecting product demand are changes in the level of local, state and federal governmental spending on roads and infrastructure projects, general economic conditions within the market area that influence the commercial and residential sectors, and prevailing interest rates.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Knife River's customers are a diverse group which includes federal, state and municipal government agencies, commercial and residential developers, and private parties. The mix of sales by customer class varies each year depending on available work. Knife River is not dependent on any single customer or group of customers for sales of its products and services, the loss of which would have a material adverse effect on its construction materials businesses. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:8pt;font-weight:700;line-height:140%">Reserve Information</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> Aggregate 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 are also utilized to estimate reserve quantities.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Estimates are based on analyses of the data described above by experienced internal mining engineers, operating personnel and geologists. Property setbacks and other regulatory restrictions and limitations are identified to determine the total area available for mining. Data described previously are used to calculate the thickness of aggregate materials to be recovered. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Topography associated with alluvial sand and gravel deposits is typically flat and volumes of these materials are calculated by applying the thickness of the resource over the areas available for mining. Volumes are then converted to tons by using an appropriate conversion factor. Typically, 1.5&#160;tons per cubic yard in the ground is used for sand and gravel deposits.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Topography associated with hard rock reserves is typically much more diverse. Therefore, using available data, a final topography map is created and computer software is utilized to compute the volumes between the existing and final topographies. Volumes are then converted to tons by using an appropriate conversion factor. Typically, 2&#160;tons per cubic yard in the ground is used for hard rock quarries.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Estimated reserves are probable reserves as defined in Securities Act Industry Guide&#160;7. The reserve estimates include only salable tonnage and thus exclude waste materials that are generated in the crushing and processing phases of the operation. Approximately 1.0 billion tons of Knife River's 1.1&#160;billion tons of aggregate reserves are permitted reserves. Remaining reserves are based on estimates of volumes that can be economically extracted and sold to meet current market and product applications. The remaining reserves are on properties that are expected to be permitted for mining under current regulatory requirements. The data used to calculate the remaining reserves may require revisions in the future to account for changes in customer requirements and unknown geological occurrences. The remaining reserve life (years) was calculated by dividing remaining reserves by the three-year average sales, including estimated sales from acquired reserves prior to acquisition, from 2018 through 2020. Actual useful lives of these reserves will be subject to, among other things, fluctuations in customer demand, customer specifications, geological conditions and changes in mining plans.</span></div><div style="height:54pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div><table

December&#160;31, 2020, are comprised of 581 million&#160;tons on properties that are owned and 524&#160;million&#160;tons that are leased. Approximately 40 percent&#160;of the tons under lease have lease expiration dates of 20&#160;years or more. The weighted average years remaining on all leases containing estimated probable aggregate reserves is approximately 20&#160;years, including options for renewal that are at Knife River's discretion. Based on a three-year average of sales from 2018 through 2020 of leased reserves, the average time necessary to produce remaining aggregate reserves from such leases is approximately 45&#160;years. Some sites have leases that expire prior to the exhaustion of the estimated reserves. The estimated reserve life assumes, based on Knife River's experience, that leases will be renewed to allow sufficient time to fully recover these reserves.</span></div><div

Some mining and construction activities are also subject to these laws. In most of the states where Knife River operates, these regulatory programs are delegated to state and local regulatory authorities. Knife River's facilities are also subject to the RCRA as it applies to the management of hazardous wastes and underground storage tank systems.

For example, certain in-water mining operations are subject to provisions of the Clean Water Act that are administered by the Army Corps. Knife River has several such operations, including gravel bar skimming and dredging operations, and Knife River has the associated required permits. The expiration dates of these permits vary, with five years generally being the longest term.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Knife River's operations are also occasionally subject to the ESA. For example, land use regulations often require environmental studies, including wildlife studies, before a permit may be granted for a new or expanded mining facility or an asphalt or concrete plant. If endangered species or their habitats are identified, ESA requirements for protection, mitigation or avoidance apply. Endangered species protection requirements are usually included as part of land use permit conditions. Typical conditions include avoidance, setbacks, restrictions on operations during certain times of the breeding or rearing season, and construction or purchase of mitigation habitat. Knife River's operations are also subject to state and federal cultural resources protection laws when new areas are disturbed for mining operations or processing plants. Land use permit applications generally require that areas proposed for mining or other surface disturbances be surveyed for cultural resources. If any are identified, they must be protected or managed in accordance with regulatory agency requirements.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The most comprehensive environmental permit requirements are usually associated with new mining operations, although requirements vary widely from state to state and even within states. In some areas, land use regulations and associated permitting requirements are minimal. However, some states and local jurisdictions have very demanding requirements for permitting new mines. Environmental impact reports are sometimes required before a mining permit application can be considered for approval. These reports can take up to several years to complete. The report can include projected impacts of the proposed project on air and water quality, wildlife, noise levels, traffic, scenic vistas and other environmental factors. The reports generally include suggested actions to mitigate the projected adverse impacts.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Provisions for public hearings and public comments are usually included in land use permit application review procedures in the counties where Knife River operates. After considering environmental, mine plan and reclamation information provided by the permittee, as well as comments from the public and other regulatory agencies, the local authority approves or denies the permit application. Denial is rare, but land use permits often include conditions that must be addressed by the permittee. Conditions may include property line setbacks, reclamation requirements, environmental monitoring and reporting, operating hour restrictions, financial guarantees for reclamation, and other requirements intended to protect the environment or address concerns submitted by the public or other regulatory agencies.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Knife River has been successful in obtaining mining and other land use permits so sufficient permitted reserves are available to support its operations. For mining operations, this often requires considerable advanced planning to ensure sufficient time is available to complete the permitting process before the newly permitted aggregate reserve is needed to support Knife River's operations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Knife River's Gascoyne surface coal mine last produced coal in 1995 but continues to be subject to reclamation requirements of the Surface Mining Control and Reclamation Act, as well as the North Dakota Surface Mining Act. Portions of the Gascoyne Mine remain under reclamation bond until the 10-year revegetation liability period has expired. A portion of the original permit has been released from bond and additional areas are currently in the process of having the bond released. Knife River intends to request bond release as soon as it is deemed possible.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Knife River did not incur any material environmental expenditures in 2020 and, except as to what may be ultimately determined with regard to the issues described in the following paragraph, Knife River does not expect to incur any material capital expenditures related to environmental compliance with current laws and regulations through 2023.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In December&#160;2000, Knife River - Northwest was named by the EPA as a PRP in connection with the cleanup of a commercial property site, acquired by Knife River - Northwest in 1999, and part of the Portland, Oregon, Harbor Superfund Site.

Most of MDU Construction Services' work is obtained on the basis of competitive bids or by negotiation of either cost-plus or fixed-price contracts. Its workforce and equipment are highly mobile, providing greater flexibility in the size and location of MDU Construction Services' market area. Competition is based primarily on price and reputation for quality, safety and reliability. The size and location of the services provided, as well as the state of the economy, are factors in the number of competitors that MDU Construction Services will encounter on any particular project. MDU Construction Services believes the diversification of the services it provides, the markets it serves in the United States and the quality and management of its workforce enable it to effectively operate in this competitive environment.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Utilities and independent contractors represent the largest customer base for this segment. Accordingly, utility and subcontract work accounts for a significant portion of the work performed by MDU Construction Services and the amount of construction contracts is dependent on the level and timing of maintenance and construction programs undertaken by customers. MDU Construction Services relies on repeat customers and strives to maintain successful long-term relationships with its customers. The mix of sales by customer class varies each year depending on available work. MDU Construction Services is not dependent on any single customer or group of customers for sales of its products and services, the loss of which would have a material adverse effect on its business. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:8pt;font-weight:700;line-height:140%">Environmental Matters</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> MDU Construction Services' operations are subject to regulation customary for the industry, including federal, state and local environmental compliance.

Operational convenience supports the use of petroleum storage tanks in several locations, which are permitted under state programs authorized by the EPA. MDU Construction Services has no ongoing remediation related to releases from petroleum storage tanks. MDU Construction Services' operations are conditionally exempt small-quantity waste generators, subject to minimal regulation under the RCRA.

The factors and other matters discussed herein are important factors that could cause actual results or outcomes for the Company to differ materially from those discussed in the forward-looking statements included elsewhere in this document. If any of the risks described below actually occur, the Company's business, prospects, financial condition or financial results could be materially harmed. The following are the most material risk factors applicable to the Company and are not necessarily listed in order of importance or probability of occurrence.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:12pt;font-weight:400;line-height:140%">Economic Risks</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">The Company is subject to government regulations that may have a negative impact on its business and its results of operations and cash flows. Statutory and regulatory requirements also may limit another party's ability to acquire the Company or impose conditions on an acquisition of or by the Company.</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company's electric and natural gas transmission and distribution businesses are subject to comprehensive regulation by federal, state and local regulatory agencies with respect to, among other things, allowed rates of return and recovery of investments and costs, financing, rate structures, customer service, health care coverage and costs, taxes, franchises; recovery of purchased power and purchased natural gas costs; and construction and siting of generation and transmission facilities. These governmental regulations significantly influence the Company's operating environment and may affect its ability to recover costs from its customers. The Company is unable to predict the impact on operating results from future regulatory activities of any of these agencies. Changes in regulations or the imposition of additional regulations could have an adverse impact on the Company's results of operations and cash flows. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">There can be no assurance that applicable regulatory commissions will determine that the Company's electric and natural gas transmission and distribution businesses' costs have been prudent, which could result in the disallowance of costs in setting rates for customers. Also, the regulatory process of approving rates for these businesses may not allow for timely and full recovery of the costs of providing services or a return on the Company's invested capital. Changes in regulatory requirements or operating conditions may require early retirement of certain assets. While regulation typically provides rate recovery for these retirements, there is no assurance regulators will allow full recovery of all remaining costs, which could leave stranded asset costs. Rising fuel costs could increase the risk that the utility businesses will not be able to fully recover those fuel costs from customers.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Approval from federal and state regulatory agencies would be needed for acquisition of the Company, as well as for certain acquisitions by the Company.

These hazards and operating risks could result in loss of human life; personal injury; property damage; environmental pollution; impairment of operations; and substantial financial losses. The Company maintains insurance against some, but not all, of these risks and losses.

Aging infrastructure is more prone to failure which increases maintenance costs, unplanned outages and the need to replace facilities. Even if properly maintained, reliability may ultimately deteriorate and negatively affect the Company&#8217;s ability to serve its customers, which could result in increased costs associated with regulatory oversight. The costs associated with maintaining the aging infrastructure and capital expenditures for new or replacement infrastructure could cause rate volatility and/or regulatory lag in some jurisdictions. If, at the end of its life, the investment costs of a facility have not been fully recovered, the Company may be adversely affected if commissions do not allow such costs to be recovered in rates.

For residential customers, heating and cooling represent the largest energy use. To the extent weather conditions are affected by climate change, customers&#8217; energy use could increase or decrease. Increased energy use by its utility customers due to weather may require the Company to invest in additional generating assets, transmission and other infrastructure to serve increased load. Decreased energy use due to weather may result in decreased revenues. Extreme weather conditions, such as uncommonly long periods of high or low ambient temperature, in general require more system backup, adding to costs, and can contribute to increased system stress, including service interruptions. Weather conditions outside of the Company's service territory could also have an impact on revenues. The Company buys and sells electricity that might be generated outside its service territory, depending upon system needs and market opportunities. Extreme temperatures may create high energy demand and raise electricity prices, which could increase the cost of energy provided to customers.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Climate change may impact a region&#8217;s economic health, which could impact revenues at all of the Company's businesses.

Although the Company has not experienced difficulties in accessing the capital markets or insurance; such efforts, if successfully directed at the Company, could increase the costs of or access to capital and interfere with business operations and ability to make capital expenditures.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:12pt;font-weight:400;line-height:140%">Other Risks</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">The Company's various businesses are seasonal and subject to weather conditions that can adversely affect the Company's operations, revenues and cash flows.</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company's results of operations can be affected by changes in the weather. Weather conditions influence the demand for electricity and natural gas and affect the price of energy commodities. Utility operations have historically generated lower revenues when weather conditions are cooler than normal in the summer and warmer than normal in the winter particularly in jurisdictions that do not have weather normalization mechanisms in place. Where weather normalization mechanisms are in place, there is no assurance the Company will continue to receive such regulatory protection from adverse weather in future rates. </span></div><div style="height:54pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div><div style="text-align:right"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:700;line-height:120%">MDU Resources Group, Inc.</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:400;line-height:120%"> Form 10-K   </span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:700;line-height:120%">25</span></div><div style="margin-top:11pt"><span><br/></span></div></div></div><hr style="page-break-after:always"/><div style="min-height:54pt;width:100%"><div><span><br/></span></div><div><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:12pt;font-weight:700;line-height:120%">Part I</span></div><div><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Adverse weather conditions, such as heavy or sustained rainfall or snowfall, storms, wind and colder weather may affect the demand for products and the ability to perform services at the construction businesses and affect ongoing operation and maintenance and construction activities for the electric and natural gas transmission and distribution businesses. In addition, severe weather can be destructive, causing outages and property damage, which could require additional remediation costs. The Company could also be impacted by drought conditions, which may restrict the availability of water supplies and inhibit the ability of the construction businesses to conduct operations. As a result, unusual or adverse weather conditions could negatively affect the Company's results of operations, financial position and cash flows.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">Competition exists in all of the Company's businesses.</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company's businesses are subject to competition. Construction services' competition is based primarily on price and reputation for quality, safety and reliability. Construction materials products are marketed under highly competitive conditions and are subject to competitive forces such as price, service, delivery time and proximity to the customer. The electric utility and natural gas industries also experience competitive pressures as a result of consumer demands, technological advances and other factors. The pipeline business competes with several pipelines for access to natural gas supplies and for transportation and storage business. New acquisition opportunities are subject to competitive bidding environments which impact prices the Company must pay to successfully acquire new properties to grow its business. The Company's failure to effectively compete could negatively affect the Company's results of operations, financial position and cash flows.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">The Company's operations may be negatively affected if it is unable to obtain, develop and retain key personnel and skilled labor forces.</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company must attract, develop and retain executive officers and other professional, technical and skilled labor forces with the skills and experience necessary to successfully manage, operate and grow the Company's businesses. Competition for these employees is high, and in some cases competition for these employees is on a regional or national basis. At times of low unemployment or economic downturns, it can be difficult for the Company to attract and retain qualified and affordable personnel. A shortage in the supply of skilled personnel creates competitive hiring markets, increased labor expenses, decreased productivity and potentially lost business opportunities to support the Company's operating and growth strategies. Additionally, if the Company is unable to hire employees with the requisite skills, the Company may be forced to incur significant training expenses. As a result, the Company's ability to maintain productivity, relationships with customers, competitive costs, and quality services is limited by the ability to employ, retain and train the necessary skilled personnel and could negatively affect the Company's results of operations, financial position and cash flows.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">The Company's construction materials and contracting and construction services businesses may be exposed to warranty claims.</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company, particularly its construction businesses, may provide warranties guaranteeing the work performed against defects in workmanship and material. If warranty claims occur, they may require the Company to re-perform the services or to repair or replace the warranted item, at a cost to the Company and could also result in other damages if the Company is not able to adequately satisfy warranty obligations. In addition, the Company may be required under contractual arrangements with customers to warrant any defects or failures in materials the Company purchased from third parties. While the Company generally requires suppliers to provide warranties that are consistent with those the Company provides to customers, if any of the suppliers default on their warranty obligations to the Company, the Company may nonetheless incur costs to repair or replace the defective materials. Costs incurred as a result of warranty claims could adversely affect the Company's results of operations, financial condition and cash flows.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">The Company is a holding company and relies on cash from its subsidiaries to pay dividends.</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company is a holding company as a result of the Holding Company Reorganization in 2019. The Company's investments in its subsidiaries comprise the Company's primary assets. The Company depends on earnings, cash flows and dividends from its subsidiaries to pay dividends on its common stock. Regulatory, contractual and legal limitations, as well as their capital requirements, affect the ability of the subsidiaries to pay dividends to the Company and thereby could restrict or influence the Company's ability or decision to pay dividends on its common stock, which could adversely affect the Company's stock price.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">Costs related to obligations under MEPPs could have a material negative effect on the Company's results of operations and cash flows.</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Various operating subsidiaries of the Company participate in approximately 68&#160;MEPPs for employees represented by certain unions.

Plans classified as being in one of these statuses are required to adopt RPs or FIPs to improve their funded status through increased contributions, reduced benefits or a combination of the two.

While the Company has policies, procedures and processes in place designed to strengthen and protect these systems, they may be vulnerable to failures or unauthorized access, due to hacking, human error, theft, sabotage, malicious software, acts of terrorism, acts of war, acts of nature or other causes. If these systems fail or become compromised, and they are not recovered in a timely manner, the Company may be unable to fulfill critical business functions. This may include interruption of electric generation, transmission and distribution facilities, natural gas storage and pipeline facilities and facilities for delivery of construction materials or other products and services, any of which could adversely affect the Company's reputation, business, cash flows and results of operations or subject the Company to legal or regulatory liabilities and increased costs. Additionally, because electric generation and transmission systems and natural gas pipelines are part of interconnected systems with other operators&#8217; facilities, a cyber-related disruption in another operator&#8217;s system could negatively impact the Company's business.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company&#8217;s accounting systems and its ability to collect information and invoice customers for products and services could be disrupted.

NERC issues comprehensive regulations and standards surrounding the security of bulk power systems and continually updates these requirements, as well as establishing new requirements with which the utility industry must comply. As these regulations evolve, the Company may experience increased compliance costs and may be at higher risk for violating these standards.

Most of these segments experience seasonality related to the industries in which they operate. The two-platform approach helps balance this seasonality and the risks associated with each type of industry. The Company is authorized to conduct business in 45 states and during peak times has over 15,600 employees. The Company&#8217;s organic investments are strong drivers of high-quality earnings growth and continue to be an important part of the Company&#8217;s growth story.

Most of the Company's products and services are considered essential to our country and our communities; therefore, operations have generally been permitted to proceed with increased social distancing measures and hygiene practices for its employees. While the Company has experienced some inefficiency impacts, including operation suspensions and interruptions at some locations to carry out preventative measures or in response to instances of positive tests, the impacts have not been material. For more information on specific impacts to each of the Company's business segments, see the following discussions in each business segment's Outlook section. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In March 2020, the President of the United States signed into law the CARES Act in response to the COVID-19 pandemic. The CARES Act provided economic relief and stimulus to support the national economy during the pandemic, including support for individuals and businesses affected by the pandemic and economic downturn. The CARES Act allowed businesses to defer payment of the employer portion of social security taxes incurred through the end of 2020. At December 31, 2020, the Company had deferred approximately $56.7&#160;million in payroll taxes related to this provision. The Company is required to pay 50&#160;percent of the payroll taxes deferred under this provision by the end of 2021 and the remaining balance by the end of 2022.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company evaluated its planned capital projects and delayed certain expenditures in 2020 to provide additional financial flexibility and to ensure projects will provide acceptable returns on investment. In addition, the Company established a task force to monitor developments related to the pandemic and implemented procedures to protect employees.

The Company has also enacted additional physical and cybersecurity measures to safeguard systems for remote work locations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Although there have been logistical and other challenges as a result of COVID-19, there were no material adverse impacts on the Company's results of operations for the year ended December 31, 2020. The Company continues to adjust its business in response to the pandemic while positioning for an economic rebound and potential opportunities to enhance its competitive position. The situation surrounding COVID-19 remains fluid and the potential for a material adverse impact on the Company increases the longer the virus impacts the level of economic activity in the United States.

earnings across all of the Company's businesses in 2020. The construction materials and contracting business experienced an increase in gross margin, primarily resulting from favorable weather conditions and higher realized materials margins on asphalt and asphalt-related products and ready-mixed concrete, as well as most other product lines. The construction services business also experienced an increase in gross margin as a result of higher inside and outside specialty contracting workloads, partially due to the businesses acquired, as well as hospitality projects, high-tech projects and natural disaster recovery work. The pipeline business experienced increased transportation volumes and revenues, largely related to organic growth projects, as well as higher storage-related revenues as a result of stronger demand for storage services. In addition, approved rate recovery positively impacted earnings at the electric and natural gas distribution businesses. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:8pt;font-weight:700;line-height:140%">2019 compared to 2018</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> The Company's consolidated earnings increased $63.2 million or 23&#160;percent in 2019 as compared to 2018.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Positively impacting the Company's earnings was an increase in gross margin at the construction services business, largely resulting from higher inside and outside specialty contracting workloads. Also contributing to the increase in earnings was an increase in gross margin at the construction materials and contracting business as a result of strong economic environments in certain states, as well as contributions from the businesses acquired and an increase in gains recognized on asset sales. The electric business also positively impacted earnings primarily due to approved rate relief in Montana and recovery of the investment in the BSSE project placed into service in the first quarter of 2019. Higher returns on the Company's benefit plan investments also increased earnings across all businesses. At the pipeline business, increased rates and volumes of natural gas being transported through its pipeline were mostly offset by the absence of a $4.2&#160;million income tax benefit recorded in 2018 relating to the reversal of a regulatory liability recorded in 2017 based on a FERC final accounting order and higher depreciation, depletion and amortization expense.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">A discussion of key financial data from the Company's business segments follows.</span></div><div id="i3ef18d2df1554b94abe60037ba667031_67"></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:12pt;font-weight:400;line-height:140%">Business Segment Financial and Operating Data </span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Following are key financial and operating data for each of the Company's business segments.

Both segments strive to be top performing utility companies measured by integrity, employee safety and satisfaction, customer service and shareholder return, while providing safe, environmentally friendly, reliable and competitively priced energy and related services to customers. The Company is focused on cultivating organic growth while managing operating costs and monitoring opportunities for these segments to retain, grow and expand their customer base through extensions of existing operations, including building and upgrading electric generation, transmission and distribution, and natural gas systems, and through selected acquisitions of companies and properties with similar operating and growth objectives 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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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, environmental and system integrity regulations. Legislative and regulatory initiatives to increase renewable energy resources and reduce GHG emissions could impact the price and demand for electricity and natural gas, as well as increase costs to produce electricity and natural gas. The segments continue to invest in facility upgrades to be in compliance with the existing and future regulations. To assist in the reduction of regulatory lag in obtaining revenue increases to align with increased investments, tracking mechanisms have been implemented in certain jurisdictions, as further discussed in Items 1 and 2 - Business Properties and Item 8 - Note 20.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In September 2019, the Pipeline and Hazardous Materials Safety Administration issued a rule for additional regulations to strengthen the safety of natural gas transmission and storage facilities and hazardous liquid pipelines. The natural gas segment has implemented procedure changes for the initial requirements and continues to evaluate procedure changes necessary for the additional requirements effective July 1,&#160;2021.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">State implementation of pollution control plans to improve visibility at Class I areas, such as national parks, under the EPA's Regional Haze Rule could require the owners of Coyote Station to incur significant new costs. If the owners decide to incur such costs, the costs could, dependent on determination by state regulatory commissions on approval to recover such costs from customers, negatively impact the Company's results of operations, financial position and cash flows. The NDDEQ's state implementation plan is due to be submitted to the EPA by July 2021. The Company expects the NDDEQ to draft a state implementation plan and share its controls selection with federal land managers of the National Park Service and the United States Fish and Wildlife Service in early 2021. Additionally, the Company is one of four owners of Coyote Station and cannot make a unilateral decision on the plant's future. The Company could be negatively impacted by the decisions of the other owners.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The electric and natural gas distribution segments are facing increased lead times on delivery of certain raw materials used in electric transmission and natural gas pipeline projects. 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, as well as delays in the manufacturing of electrical equipment as a result of the COVID-19 pandemic, including delays in trucking times and issuance of permits for large and heavy loads. The Company continues to monitor the material lead times and is working with manufacturers to proactively order such materials to help mitigate the risk of delays due to extended lead times.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 regulatory constraints, 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 costs and lead times, extensive permitting procedures, and federal and state legislative and regulatory initiatives, which will likely necessitate increases in electric energy prices.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Revenues are impacted by both customer growth and usage, the latter of which is primarily impacted by weather, as well as impacts associated with commercial and industrial slow-downs, including economic recessions, and energy efficiencies. 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 both electric and natural gas customers has tended to decline as more efficient appliances and furnaces are installed, and as the Company has implemented conservation programs. Natural gas weather normalization and 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, as further discussed in Items 1 and 2 - Business Properties.</span></div><div

In response to the pandemic, the Company instituted certain measures to help protect its employees from exposure to COVID-19 and to curb potential spread of the virus in customer homes and facilities, including suspension of disconnects due to nonpayment of bills. The Company also waived late payment fees effective April&#160;1, 2020, to help customers experiencing financial hardships. As a consequence of the suspended disconnects and waived late fees, the Company's cash flows and collection of receivables have been affected. The Company reinstated disconnects and late payment fees in five of its eight states effective September 1, 2020, and the Company reinstated disconnects and late payment fees to certain customer classes in another two states effective January 1, 2021. The Company has experienced some impacts to its commercial and industrial electric and natural gas loads associated with reduced economic activity due to the COVID-19 pandemic and oil price impacts, as further discussed below. The Company expects this downward trend on demand to continue throughout the pandemic. The Company temporarily implemented cost containment measures in response to the COVID-19 pandemic, including reduced employee travel and temporary delays in training for employees, as well as delays in filling open positions and contract work. The Company has filed requests for the use of deferred accounting for costs related to the COVID-19 pandemic in most of the jurisdictions in which it operates; the Company has deferred an immaterial amount related to the pandemic to date. The Company's outstanding filings by jurisdiction related to the COVID-19 pandemic are discussed in Item 8 - Note 20.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company expects these segments will grow rate base by approximately 5&#160;percent annually over the next five years on a compound basis. Operations are spread across eight states where the Company expects customer growth to be higher than the national average. In 2020 and 2019, these segments experienced retail customer growth of approximately 1.8&#160;percent each year and expects customer growth to continue to average 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 and replacement electric and natural gas systems.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">These segments are exposed to energy price volatility. Rate schedules in the jurisdictions in which the Company's natural gas distribution segment operates contain clauses that permit the Company to file for rate adjustments for changes in the cost of purchased gas. Although changes in the price of natural gas are passed through to customers and have minimal impact on the Company's earnings, the natural gas distribution segment's customers benefit from lower natural gas prices through the Company's utilization of storage and fixed price contracts. Additionally, the Company has implemented risk mitigation measures to minimize the price volatility associated with natural gas costs through derivative contracts at Cascade. For further discussion on the Company's derivative instruments, see Item 8 - Note 2. Demand for the Company's regulated energy delivery services could be impacted by reduced oil and natural gas exploration and production activity. The Company continues to monitor natural gas prices, as well as the oil and natural gas production levels.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In February 2019, the Company announced that it intends to retire three aging coal-fired electric generating units, resulting from the Company's analysis showing that the plants are no longer expected to be cost competitive for customers. The retirements are expected to be in March 2021 for Unit 1 at Lewis &amp; Clark Station in Sidney, Montana, and in early 2022 for Units 1 and 2 at Heskett Station near Mandan, North Dakota. In addition, the Company announced that it intends to construct Heskett Unit 4, an 88-MW simple-cycle natural gas-fired combustion turbine peaking unit at the existing Heskett Station near Mandan, North Dakota. Heskett Unit 4 production costs coupled with the MISO market purchases are expected to be about half the total cost of continuing to run the coal-fired electric generating units at Heskett and Lewis &amp; Clark stations. Heskett Unit 4 was included in the Company's integrated resource plan submitted to the NDPSC in July 2019. On August&#160;28, 2019, the Company filed for an advanced determination of prudence with the NDPSC for Heskett Unit 4. This request was approved by the NDPSC on August 5, 2020. Heskett Unit 4 is expected to be placed into service in 2023. The Company filed, and the commissions approved, requests with the NDPSC, MTPSC and SDPUC for the usage of deferred accounting for the costs related to the retirement of Unit 1 at Lewis &amp; Clark Station and Units 1 and 2 at Heskett Station.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In December 2020, the governor of Washington outlined a climate policy package that included House Bill 1084, which would eliminate all onsite fossil fuel emissions in new buildings by 2030 and eliminate fossil fuels from existing buildings by 2050, among other things.

The completion of organic growth projects has contributed to the increased volumes of natural gas the Company transports through its system. Reduced global oil demand due to the COVID-19 pandemic and disagreements in oil supply levels between the Organization of the Petroleum Exporting Countries and other countries led to record low oil prices during the first quarter of 2020; </span></div><div style="height:54pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:700;line-height:120%">40   MDU Resources Group, Inc.</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:400;line-height:120%"> Form 10-K</span></div><div style="margin-top:11pt"><span><br/></span></div></div></div><hr style="page-break-after:always"/><div style="min-height:54pt;width:100%"><div style="text-align:right"><span><br/></span></div><div style="text-align:right"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:12pt;font-weight:700;line-height:120%">Part II</span></div><div style="padding-right:9pt"><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">however, oil prices started to recover after the first quarter of 2020 as states and other countries started to reopen. Although low oil prices have slowed drilling activities and led to the shut-in of certain wells, producers continue to bring wells back online and the Company continues to focus on growth and improving existing operations through organic projects in all areas in which it operates. The national record levels of natural gas supply over the last few years have moderated the need for storage services and put downward pressure on natural gas prices and minimized price volatility. While the Company believes there will continue to be varying pressures on natural gas production levels and prices due to these circumstances, low natural gas prices provide growth opportunity for industrial supply related projects and seasonal pricing differentials provide opportunities for storage services. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In January 2019, the Company announced the North Bakken Expansion project, which includes construction of a new pipeline, compression and ancillary facilities to transport natural gas from core Bakken production areas near Tioga, North Dakota, to a new connection with Northern Border Pipeline in McKenzie County, North Dakota. Construction is expected to begin in the second quarter of 2021 with an estimated in-service date late in 2021, which is dependent on regulatory and environmental permitting. On February 14, 2020, the Company filed with the FERC its application for this project. On July&#160;28, 2020, the Company filed an amendment to its application with the FERC reflecting a decrease to the design capacity from 350 MMcf per day to 250 MMcf per day by reducing compression due to delays in forecasted growth levels of natural gas production in the Bakken region. Further, as a result of the forecasted Bakken oil and associated natural gas production delays driven by COVID-19 pandemic-related demand decreases and commodity price impacts, the Company negotiated adjustments to certain long-term customer commitments. A portion of the first-year committed volumes have been delayed one year and, through a combination of rate, volume and term adjustments, the overall project return profile remains unchanged and is expected to be accretive to earnings of the Company. These long-term take or pay customer contracts support the project at a design capacity of 250 MMcf per day, which can be readily expanded when forecasted growth levels rebound. On December&#160;17, 2020, the FERC issued its environment assessment for the project. FERC approval of the project is anticipated in early 2021.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In December 2019, the Company entered into a purchase and sale agreement to divest of the Company's regulated natural gas gathering assets located in Montana and North Dakota, which included approximately 400 miles of natural gas gathering pipelines and associated compression and ancillary facilities.

The sale closed in April 2020 with an effective date of January 1, 2020.

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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 continued acquisition activity supports this strategy.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">As one of the country's largest sand and gravel producers, the segment continues to strategically manage its approximately 1.1 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. The Company's aggregate reserves are naturally declining and as a result, the Company seeks acquisition opportunities to replace the reserves. In the fourth quarter of 2020, the Company acquired the assets of McMurry Ready-Mix Co., an aggregates and concrete supplier located in Casper, Wyoming. The acquisition included nearly 100 million tons of aggregate reserves. In the first quarter of 2019, the Company purchased additional aggregate deposits in Texas that were estimated to contain a 40-year supply of high-quality aggregates for projected local market needs. Also during 2019, the Company increased aggregate reserves by approximately 40&#160;million tons largely due to strategic asset purchases. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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. Such volatility can have an impact on the segment's margins, including fixed-price construction contracts that are particularly vulnerable to the volatility of energy and material prices. 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 governmental infrastructure spending. Accordingly, operating results in any particular period may not be indicative of the results that can be expected for any other period.</span></div><div style="height:54pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div><div style="text-align:right"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:700;line-height:120%">MDU Resources Group, Inc.</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:400;line-height:120%"> Form 10-K   </span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:700;line-height:120%">41</span></div><div style="margin-top:11pt"><span><br/></span></div></div></div><hr style="page-break-after:always"/><div style="min-height:54pt;width:100%"><div><span><br/></span></div><div><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:12pt;font-weight:700;line-height:120%">Part II</span></div><div><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The segment also faces challenges in the recruitment and retention of employees.

Asphalt and asphalt-related product margins increased $21.3 million overall. Strong pricing for ready-mixed concrete in most markets resulted in 1.9&#160;percent higher margins. Contracting bid margins positively impacted gross margin by $6.5 million partially resulting from lower direct costs associated with having a longer construction season due to favorable weather conditions. The Company also benefited across all product lines from lower fuel costs. Partially offsetting these increases was lower gains on asset sales in certain regions of approximately $6.8&#160;million. </span></div><div style="margin-top:8pt;padding-left:9pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:400;line-height:120%">Selling, general and administrative expense: </span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:120%">Increase of $5.6 million, primarily related to higher payroll-related costs of $2.2 million and increased amortization of intangible assets associated with the businesses acquired.</span></div><div style="margin-top:8pt;padding-left:9pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:400;line-height:120%">Other income: </span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:120%">Decrease of $800,000, largely the result of an out-of-period adjustment to benefit expense in the fourth quarter of 2020, as discussed in Item 8 -

The Company has implemented safety and social distancing measures for its employees that are not able to work from home and has experienced some inefficiencies and additional costs in relation to these measures but, for the most part, has been able to continue business processes with minimal interruptions. The Company also continues to monitor job progress and service work and at this time has not experienced significant delays, cancellations or disruptions due to the pandemic. The Company will continue to monitor the demand for construction materials and contracting services as such services may be reduced by recessionary impacts of the pandemic as the traditional customers for these services reduce capital expenditures. State and local mandates were issued in response to the COVID-19 pandemic requiring individuals to stay in place, leading to a reduction in fuel consumption in the United States, which directly reduces fuel tax collections. In addition, states, cities and counties across the country are experiencing low sales tax and other revenues as a result of the COVID-19 pandemic. The reduction in tax collections may impact funds available for public infrastructure projects, which in turn could have a material adverse impact on the Company's results of operations, financial position and cash flows. Meanwhile, a comprehensive infrastructure funding program, if adopted, by the United States Congress could positively impact the segment.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The segment's vertically integrated aggregate-based business model provides the Company with the ability to capture margin throughout the sales delivery process. 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 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 projects are, however, dependent on federal and state 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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">During 2020 and 2019, the Company made strategic asset purchases and completed several acquisitions that support the Company's long-term strategy to expand its market presence. In the first quarter of 2020, the Company acquired the assets of Oldcastle Infrastructure Spokane, a prestressed-concrete business located in Spokane, Washington. In the fourth quarter of 2020, the Company acquired the assets of McMurry Ready-Mix Co., an aggregates and concrete supplier located in Casper, Wyoming. The Company continues to evaluate additional acquisition opportunities.

A significant portion of the Company's backlog relates to street and highway construction. The Company expects to complete a significant amount of backlog at December&#160;31, 2020, during the next 12 months.</span></div><div id="i3ef18d2df1554b94abe60037ba667031_79"></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Construction Services</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:9pt;font-style:italic;font-weight:700;line-height:140%">Strategy and challenges</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> The construction services segment provides inside and outside specialty contracting, as discussed in Items 1 and 2 - Business Properties. The construction services segment focuses on safely executing projects; providing a superior return on investment by building new and strengthening existing customer relationships; ensuring quality service; effectively controlling costs; 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. The growth experienced by the segment in recent years is due in part to its ability to support national customers in most of the regions in which it operates.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 from 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; disruptions to the supply chain due to transportation delays, travel restrictions, raw material cost increases and shortages and closures of businesses or facilities; declines or delays in new projects due to the cyclical nature of the construction industry; and other factors. These challenges may also impact the risk of loss on certain projects. Accordingly, operating results in any particular period may not be indicative of the results that can be expected for any other period.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The need to ensure available specialized labor resources for projects also drives strategic relationships with customers and project margins.

new project opportunities that the Company continues to be awarded across its diverse operations, particularly inside specialty electrical and mechanical contracting in the hospitality, high-tech and public industries. The Company's outside power, communications and natural gas specialty contracting also have a high volume of available work. The Company expects to complete a significant amount of the backlog at December&#160;31, 2020, during the next 12 months. Additionally, the Company continues to further evaluate potential acquisition opportunities that would be accretive to earnings of the Company and continue to grow the Company's backlog.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In support of the Company's strategic plan to grow through acquisitions, the Company acquired PerLectric, Inc., an electrical construction company in Fairfax, Virginia, in the first quarter of 2020.

and available borrowing capacity of $736.3&#160;million under the outstanding credit facilities of the Company's subsidiaries. During the first quarter of 2020, short-term capital markets were disrupted as a result of the COVID-19 pandemic. Consequently, the Company temporarily borrowed under its revolving credit agreements in addition to accessing the commercial paper markets and maintained higher than normal cash balances to ensure liquidity during this volatile period. At December&#160;31, 2020, all borrowings under the revolving credit agreements for Montana-Dakota and Centennial had been repaid. The Company expects to meet its obligations for debt maturing within 12 months and its other operating and capital requirements from various sources, including internally generated funds; credit facilities and commercial paper of the Company's subsidiaries, as described later in Capital resources; and the issuance of debt and equity securities if necessary.</span></div><div id="i3ef18d2df1554b94abe60037ba667031_94"></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Cash flows</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">Operating activities</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> The changes in cash flows from operating activities generally follow the results of operations as discussed in Business Segment Financial and Operating Data and are also affected by changes in working capital.

The increase in cash flows provided by operating activities is reflective of the increased earnings across all businesses. The increase in cash flows provided by operating activities was largely driven by stronger collection of accounts receivable at the construction services business and decreased receivables at the construction materials and contracting business as compared to the prior period as a result of lower contracting revenues. Also contributing to the increase in cash flows provided by operating activities was the decrease in natural gas purchases in 2020 as a result of milder temperatures and lower gas costs and recovery of purchased gas cost adjustment balances at the natural gas distribution business. The Company also benefited from the deferral of payroll taxes related to the CARES Act and the absence of pension contributions at all of its businesses. Partially offsetting these increases was higher cash needs due to decreased bonus depreciation for tax purposes taken on qualified property in 2020 as compared to 2019 and a decrease in deferred taxes as a result of the purchased gas cost adjustment recorded in 2019.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Cash flows provided by operating activities in 2019 were $542.3 million compared to $499.9 million in 2018. The increase in cash flows provided by operating activities was largely driven by increased earnings from higher workloads at the construction businesses, which were partially offset by an increase in accounts receivable as a result of the higher workloads. Lower inventory balances due to higher workloads at the construction materials and contracting business in 2019 as compared to the increase in inventory balances in 2018 due to the activity of acquired businesses also contributed to the increase. Partially offsetting these increases were higher natural gas purchases including the effects of colder weather, higher gas costs and timing of collection of such balances from customers at the natural gas distribution business, as well as higher pension contributions at all of the businesses.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">Investing activities</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> Cash flows used in investing activities in 2020 were $630.2&#160;million compared to $603.9&#160;million in 2019. The increase in cash used was primarily related to additional cash needs for acquisition activity in 2020 compared to 2019 at the construction businesses, increased capital expenditures in 2020 at the electric business and lower proceeds on asset sales in 2020 at the construction materials and contracting business. Partially offsetting these increases were decreased capital expenditures in 2020 at the construction materials and contracting business, proceeds on the natural gas gathering asset sales at the pipeline business and higher proceeds on asset sales in 2020 at the construction services businesses.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Cash flows used in investing activities in 2019 was $603.9&#160;million compared to $710.9 million in 2018.

Plan assets consist of investments in equity and fixed-income securities. Various actuarial assumptions are used in calculating the benefit expense (income) and liability (asset) related to the pension plans. Actuarial assumptions include assumptions about the discount rate and expected return on plan assets. At December&#160;31, 2020, the pension plans' accumulated benefit obligations exceeded these plans' assets by approximately $53.5 million. Pretax pension income reflected in the Consolidated Statements of Income for the year ended December&#160;31, 2020, was $684,000. Pretax pension expense reflected in the Consolidated Statements of Income for the years ended December 31, 2019 and 2018, was $2.5 million and $843,000, respectively. The Company's pension income is currently projected to be approximately $1.7&#160;million in 2021. Funding for the pension plans is actuarially determined. The Company has no minimum funding requirements for its defined benefit pension plans for 2021 due to an additional contribution of $20.0&#160;million in 2019. There were no minimum required contributions for the year ended December&#160;31, 2020, and the minimum required contributions for the years ended December 31, 2019 and 2018, were approximately $4.9&#160;million and $6.1 million, respectively.

The fair value of each reporting unit is determined using a weighted combination of income and market approaches. The Company uses a discounted cash flow methodology for its income approach. Under the income approach, the discounted cash flow model determines fair value based on the present value of projected cash flows over a specified period and a residual value related to future cash flows beyond the projection period. Both values are discounted using a rate which reflects the best estimate of the risk adjusted capital cost at each reporting unit. Risk adjusted capital cost, which varies by reporting unit and was in the range of 4&#160;percent to 8&#160;percent, was utilized in the goodwill impairment test performed in the fourth quarter of 2020. The goodwill impairment test also utilized a long-term growth rate projection, which varies by reporting unit and was in the range of approximately 1&#160;percent to 3&#160;percent, in the goodwill impairment test performed in the fourth quarter of 2020. Under the market approach, the Company estimates fair value using various multiples derived from enterprise value to EBITDA for comparative peer companies for each respective reporting unit. These multiples are applied to operating data for each reporting unit to arrive at an indication of fair value. In addition, the Company adds a reasonable control premium when calculating the fair value utilizing the peer multiples, which is estimated as the premium that would be received in a sale in an orderly transaction between market participants. The Company believes that the estimates and assumptions used in its impairment assessments are reasonable and based on available market information. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Business combinations</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company accounts for acquisitions on the Consolidated Financial Statements starting from the date of the acquisition, which is the date that control is obtained. The acquisition method of accounting requires acquired assets and liabilities assumed be recorded at their respective fair values as of the date of the acquisition. The excess of the purchase price over the fair value of the assets acquired and liabilities assumed is recorded as goodwill. The estimation of fair values of acquired assets and liabilities assumed by the Company requires significant judgment and requires various assumptions. Although independent appraisals may be used to assist in the determination of the fair value of certain assets and liabilities, the appraised values may be based on significant estimates provided by management. The amounts and useful lives assigned to depreciable and amortizable assets compared to amounts assigned to goodwill, which is not amortized, can affect the results of operations in the period of and periods subsequent to a business combination. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In determining fair values of acquired assets and liabilities assumed, the Company uses various observable inputs for similar assets or liabilities in active markets and various unobservable inputs, which includes the use of valuation models. Fair values are based on various factors including, but not limited to, age and condition of property, maintenance records, auction values for equipment with similar characteristics, recent sales and listings of comparable properties, data collected from drill holes and other subsurface investigations and geologic data. The Company primarily uses the market and cost approaches in determining the fair value of land and property, plant and equipment. A combination of the market and income approaches are used for aggregate reserves and intangibles, primarily a discounted cash flow model.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">There is a measurement period after the acquisition date during which the Company may adjust the amounts recognized for a business combination. Any such adjustments are recorded in the period the adjustment is determined with the corresponding offset to goodwill. These adjustments are typically based on obtaining additional information that existed at the acquisition date regarding the assets acquired and the liabilities assumed. The measurement period ends once the Company has obtained all necessary information that existed as of the acquisition date, but does not extend beyond one year from the date of the acquisition. Once the measurement period has ended, any adjustments to assets acquired or liabilities assumed are recorded in income from continuing operations. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Regulatory accounting</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company is subject to rate regulation by state public service commissions and/or the FERC. The Company's regulated businesses account for certain income and expense items under the provisions of regulatory accounting, which require these businesses to defer as regulatory assets or liabilities certain items that would have otherwise been reflected as expense or income, respectively, based on the expected regulatory treatment in future rates. Regulatory assets generally represent incurred or accrued costs that have been deferred and are expected to be recovered in rates charged to customers. Regulatory liabilities generally represent amounts that are expected to be refunded to customers in future rates or amounts collected in current rates for future costs. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Management continually assesses the likelihood of recovery in future rates of incurred costs and refunds to customers associated with regulatory assets and liabilities. Decisions made by the various regulatory agencies can directly impact the amount and timing of these items. Therefore, expected recovery or flowback of these deferred items generally is based on specific ratemaking decisions or precedent for each item. If future recovery of costs is no longer probable, the Company would be required to include those costs in the statement of income or accumulated other comprehensive income (loss) in the period in which it is no longer deemed probable. The Company believes that the accounting subject to rate regulation remains appropriate and its regulatory assets are probable of recovery in current rates or in future rate proceedings. At December&#160;31, 2020 and 2019, the Company's regulatory assets were $447.9&#160;million and $417.4&#160;million, respectively, and regulatory liabilities were $459.5&#160;million and $490.3&#160;million, respectively.</span></div><div style="height:54pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div><div style="text-align:right"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:700;line-height:120%">MDU Resources Group, Inc.</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:400;line-height:120%"> Form 10-K   </span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:700;line-height:120%">51</span></div><div style="margin-top:11pt"><span><br/></span></div></div></div><hr style="page-break-after:always"/><div style="min-height:54pt;width:100%"><div><span><br/></span></div><div><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:12pt;font-weight:700;line-height:120%">Part II</span></div><div><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Revenue recognition</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. 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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company recognizes construction contract revenue over time using an input method based on 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. For the years ended December&#160;31, 2020 and 2019, the Company's total construction contract revenue was $3.1&#160;billion and $2.8&#160;billion, respectively.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Pension and other postretirement benefits</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company has noncontributory defined benefit pension plans and other postretirement benefit plans for certain eligible employees.

Another key variable in determining benefit expense or income is the discount rate. In selecting the discount rate, the Company matches forecasted future cash flows of the pension and postretirement plans to a yield curve which consists of a hypothetical portfolio of high-quality corporate bonds with varying maturity dates, as well as other factors, as a basis. The Company's pension and other postretirement benefit plan assets are primarily made up of equity and fixed-income investments. Fluctuations in actual equity and bond market returns, as well as changes in general interest rates, may result in increased or decreased pension and other postretirement benefit costs in the future. Management estimates the rate of compensation increase based on long-term assumed wage increases and the health care cost trend rates are determined by historical and future trends. The Company estimates that a 50-basis point decrease in the discount rate or in the expected return on plan assets would each increase expense by approximately $2.0 million (after-tax) for the year ended December&#160;31, 2020.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company believes the estimates made for its pension and other postretirement benefits are reasonable based on the information that is known when the estimates are made.

Judgments related to income taxes require the recognition in the Company's financial statements that a tax position is more-likely-than-not to be sustained on audit.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Judgment and estimation is required in developing the provision for income taxes and the reporting of tax-related assets and liabilities and, if necessary, any valuation allowances. The interpretation of tax laws can involve uncertainty, since tax authorities may interpret such laws differently. Actual income tax could vary from estimated amounts and may result in favorable or unfavorable impacts to net income, cash flows and tax-related assets and liabilities. In addition, the effective tax rate may be affected by other changes including the allocation of property, payroll and revenues between states.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company assesses the deferred tax assets for recoverability taking into consideration historical and anticipated earnings levels; the reversal of other existing temporary differences; available net operating losses and tax carryforwards; and available tax planning strategies that could be implemented to realize the deferred tax assets. Based on this assessment, management must evaluate the need for, and amount of, a valuation allowance against the deferred tax assets. As facts and circumstances change, adjustment to the valuation allowance may be required.</span></div><div id="i3ef18d2df1554b94abe60037ba667031_121"></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:12pt;font-weight:400;line-height:140%">Non-GAAP Financial Measures</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Business Segment Financial and Operating Data 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 net income (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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Adjusted gross margin includes operating revenues less the 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 as they are calculated as a percentage of revenues. For these reasons, period over period, the segments' operating income (loss) is generally not impacted. 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 to investors in assessing the Company's utility performance as management has the ability to influence control over the remaining operating expenses.</span></div><div style="height:54pt;position:relative;width:100%"><div

Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Management assessed the effectiveness of the Company's internal control over financial reporting as of December&#160;31, 2020.

Ordinarily the Company&#8217;s contracts represent a single distinct performance obligation due to the highly interdependent and interrelated nature of the underlying goods or services.

Company&#8217;s regulated utility businesses, it provides electric and natural gas services to customers, and generates, transmits, and distributes electricity. The Company is subject to rate regulation by federal and state utility regulatory agencies (collectively, the &#8220;Commissions&#8221;), which have jurisdiction with respect to the rates of electric and natural gas distribution companies in states where the Company operates. The Company&#8217;s regulated utility businesses account for certain income and expense items under the provisions of regulatory accounting, which requires these businesses to defer as regulatory assets or liabilities certain items that would have otherwise been reflected as expense or income, respectively, based on the expected regulatory treatment in future rates. The expected recovery or flowback of these deferred items generally is based on specific ratemaking decisions or precedent for each item.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Rates are determined and approved in regulatory proceedings based on an analysis of the Company&#8217;s costs to provide utility service and a return on the Company&#8217;s investment in the regulated utility businesses.&#160;Regulatory decisions can have an impact on the recovery of costs, the rate of return earned on investment, and the timing and amount of assets to be recovered by rates.&#160;The regulation of rates is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital.&#160;Decisions to be made by the Commissions in the future will impact the accounting for regulated operations.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Accounting for the economics of rate regulation impacts multiple financial statement line items and disclosures, such as property, plant, and equipment; regulatory assets and liabilities; operating revenues; operation and maintenance expense; and depreciation expense. We identified the impact of rate regulation as a critical audit matter due to the significant judgments made by management to support its assertions about impacted account balances and disclosures and the degree of subjectivity involved in assessing the impact of future regulatory orders on the financial statements. Management judgments include assessing the likelihood of (1)&#160;recovery in future rates of incurred costs and (2)&#160;refunds to customers. Given management&#8217;s accounting judgments are based on assumptions about the outcome of future decisions by the Commissions, auditing these judgments requires specialized knowledge of accounting for rate regulation due to its inherent complexities.</span></div><div style="margin-top:3pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:400;line-height:140%">How the Critical Audit Matter Was Addressed in the Audit</span></div><div style="margin-top:3pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Our audit procedures related to the uncertainty of future decisions by the Commissions included the following, among others:</span></div><div style="margin-top:3pt;padding-left:22.5pt;text-indent:-9pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">&#8226;</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%;padding-left:5pt">We tested the design and operating effectiveness of management&#8217;s controls over the evaluation of the likelihood of (1)&#160;the recovery in future rates of costs incurred as property, plant, and equipment and deferred as regulatory assets; and (2)&#160;a refund or a future reduction in rates that should be reported as regulatory liabilities.

The guidance added, 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 removed, 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 applies to certain contract modifications, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. LIBOR is expected to be retired with a full phase-out by the end of 2021 and replaced by new reference rates, which includes SOFR.

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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 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 30 days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The pipeline 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 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, 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 12 days of receipt of the invoice. For gathering contracts not governed by the tariff, amounts are due within 20 days of invoice receipt. For other contracts not governed by the tariff, payment terms are net 30 days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 an input method based on the cost-to-cost measure of progress on a project. This 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 30 days of receipt. There are no material obligations for returns, refunds or other similar obligations.</span></div></ix:nonNumeric></ix:continuation><div style="height:54pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div><div style="text-align:right"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:700;line-height:120%">MDU Resources Group, Inc.</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:400;line-height:120%"> Form 10-K   </span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:700;line-height:120%">67</span></div><div style="margin-top:11pt"><span><br/></span></div></div></div><hr style="page-break-after:always"/><div style="min-height:54pt;width:100%"><div><span><br/></span></div><div><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:12pt;font-weight:700;line-height:120%">Part II</span></div><div><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:98.900%"></td><td style="width:0.1%"></td></tr><tr style="height:3pt"><td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"></td></tr></table></div></div><ix:continuation id="i29d754eefaea460aac78208145d29c24" continuedAt="i3ecf5ea3bd7d46459a1529a7a110ee32"><ix:continuation id="i32bd5f218a1b4427900bafd1a7121664" continuedAt="i3df6f61d129f448492c855b89a84524e"><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The construction services segment generates revenue from specialty contracting services which also includes the sale of construction equipment and other supplies.

The Company expects to record adjustments as it accumulates the information needed to estimate the fair value of assets acquired and liabilities assumed, including working capital balances, estimated fair value of identifiable intangible assets, property, plant and equipment, total consideration and goodwill. The excess of the purchase price over the aggregate fair values is recorded as goodwill. The Company calculated the fair value of the assets acquired in 2020 and 2019 using a market or cost approach (or a combination of both). 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 final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill, and will be made as soon as practical, but no later than 12 months from the respective acquisition dates. Any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations.</ix:nonNumeric></span></div></ix:continuation><div id="i3ef18d2df1554b94abe60037ba667031_2565"></div><ix:continuation id="i5daf87c79d9a423f840e0e8932a11bd9" continuedAt="id337ba92bc204c8aadb19f33d82fb85f"><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Receivables and allowance for expected credit losses</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"><ix:nonNumeric contextRef="i296bdc34c93446c7917e04b8bdca6581_D20200101-20201231" name="us-gaap:ReceivablesTradeAndOtherAccountsReceivableAllowanceForDoubtfulAccountsPolicy" id="id3VybDovL2RvY3MudjEvZG9jOjNlZjE4ZDJkZjE1NTRiOTRhYmU2MDAzN2JhNjY3MDMxL3NlYzozZWYxOGQyZGYxNTU0Yjk0YWJlNjAwMzdiYTY2NzAzMV8yNTY1L2ZyYWc6NzUwZDAzNTk1MzM3NDZmYmIyMmUwYmQ5NDY1MmNiZDcvdGV4dHJlZ2lvbjo3NTBkMDM1OTUzMzc0NmZiYjIyZTBiZDk0NjUyY2JkN183Njk2NTgxNDAxODM3_150899ba-3eba-4c00-8b94-94b633564167" continuedAt="ia8f2f7238e6a47e683c9eafd04648b07" escape="true">Receivable consists primarily of trade receivables from the sale of goods and services, which are recorded at the invoiced amount, and contract assets, net of expected credit losses.

The Company determines the lease term based on the non-cancelable and cancelable periods in each contract. The non-cancelable period consists of the term of the contract that is legally enforceable and cannot be canceled by either party without incurring a significant penalty. The cancelable period is determined by various factors that are based on who has the right to cancel a contract. If only the lessor has the right to cancel the contract, the Company will assume the contract will continue. If the lessee is the only party that has the right to cancel the contract, the Company looks to asset, entity and market-based factors.

Upon settlement of the liability, the Company either settles the obligation for the recorded amount or incurs a gain or loss at its non-regulated operations or incurs a regulatory asset or liability at its regulated operations.</ix:nonNumeric></span></div></ix:continuation><div id="i3ef18d2df1554b94abe60037ba667031_2780"></div><ix:continuation id="i86145b47428647ac9cf17dbae86b505d" continuedAt="ic4547426adea4d79a2aa06328c17b337"><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Stock-based compensation</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"><ix:nonNumeric contextRef="i296bdc34c93446c7917e04b8bdca6581_D20200101-20201231" name="us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy" id="id3VybDovL2RvY3MudjEvZG9jOjNlZjE4ZDJkZjE1NTRiOTRhYmU2MDAzN2JhNjY3MDMxL3NlYzozZWYxOGQyZGYxNTU0Yjk0YWJlNjAwMzdiYTY2NzAzMV8yNzgwL2ZyYWc6OGI5MWZjYzc4MjJlNGJiZjljOGQ5NWVjMWVmZjJjOTIvdGV4dHJlZ2lvbjo4YjkxZmNjNzgyMmU0YmJmOWM4ZDk1ZWMxZWZmMmM5Ml82MDQ3MzEzOTU0Mjk4_e5595dce-ed2f-47be-b00a-38cac512cb0b" continuedAt="ie47b5d0e826345ccbf1d684e2fefa5a6" escape="true">The Company determines compensation expense for stock-based awards based on the estimated fair values at the grant date and recognizes the related compensation expense over the vesting period.

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.</span></div><ix:nonNumeric

Excluded from remaining performance obligations are potential orders under master service agreements.

The Company files for rate adjustments to seek recovery of operating costs and capital investments, as well as reasonable returns as allowed by regulators.

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 confirmed that contaminants have affected soil and groundwater at the site, as well as sediments in the adjacent Port Washington Narrows. 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.

The information is unconsolidated and is presented for the parent company only, MDU Resources Group, Inc. (the Company) as of and for the years ended December&#160;31, 2020 and 2019. Prior to the Holding Company Reorganization, the Company included Montana-Dakota and Great Plains, public utility divisions of the Company as of December&#160;31, 2018. On January 2, 2019, the Company announced the completion of the Holding Company Reorganization, which resulted in Montana-Dakota and Great Plains becoming a subsidiary of the Company. Immediately after consummation, the Company had, on a consolidated basis, the same assets, businesses and operations as it had immediately prior to the reorganization. For more information on the reorganization, see Item 8 - Note 1. The prior periods have not been restated and reflect the condensed financial information of Montana-Dakota and Great Plains as of and for the year ended December&#160;31, 2018. Due to the completion of the Holding Company Reorganization, the presentation of the year ended December&#160;31, 2018, will vary from that of and for the years ended December&#160;31, 2020 and 2019. In Schedule I, investments in subsidiaries are presented under the equity method of accounting where the assets and liabilities of the subsidiaries are not consolidated. The investments in net assets of the subsidiaries are recorded on the Condensed Balance Sheets. The income from subsidiaries is reported as equity in earnings of subsidiaries on the Condensed Statements of Income. The material cash inflows on the Condensed Statements of Cash Flows are primarily from the dividends and other payments received from its subsidiaries and the proceeds raised from the issuance of equity securities. The consolidated financial statements of MDU Resources Group, Inc. reflect certain businesses as discontinued operations. These statements should be read in conjunction with the consolidated financial statements and notes thereto of MDU Resources Group, Inc.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:400;line-height:140%">Earnings per common share</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> Please refer to the Consolidated Statements of Income of the registrant for earnings per common share.

Governmental restrictions and guidelines implemented to control the spread of COVID-19 reduced commercial and interpersonal activity throughout the Company's areas of operation. Most of the Company's products and services are considered essential and accordingly operations have been generally allowed to continue. The Company has experienced some inefficiency impacts, including operation suspensions and interruptions at some locations to carry out preventive measures or in response to instances of positive tests or quarantines. The Company has assessed the impacts of the COVID-19 pandemic on its results of operations for the twelve months ended December&#160;31, 2020, and determined there were no material adverse impacts.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;In the first quarter of 2020, the Company recorded an out-of-period adjustment to correct the recognition of revenue on a construction contract, which was the result of an overstatement of operating revenue and receivables of $7.7&#160;million and an understatement of operating expense and accounts payable of $1.2&#160;million in the year ended December&#160;31, 2019. This adjustment resulted in an after-tax reduction to net income of $6.7&#160;million in the first quarter of 2020. The Company evaluated the impact of the out-of-period adjustment and concluded it was not material to any previously issued interim and annual consolidated financial statements and the adjustment was not material to the three months ended March&#160;31, 2020, or the twelve months ended December&#160;31, 2020.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;In the fourth quarter of 2020, the Company recorded an out-of-period adjustment to correct the recognition of net periodic benefit cost and other comprehensive income associated with the Company's benefit plans, which was the result of the previous overstatement of benefit plan expenses of $6.5&#160;million, understatement of accumulated other comprehensive loss of $2.7&#160;million and overstatement of regulatory liabilities of $3.8&#160;million from 2006 through 2020. This adjustment resulted in an after-tax increase to net income of $4.4&#160;million in the fourth quarter of 2020. The Company evaluated the impact of the out-of-period adjustment, individually and in the aggregate with the previously mentioned out-of-period adjustment, and concluded it was not material to any previously issued interim and annual consolidated financial statements and the adjustment was not material to the three and twelve months ended December&#160;31, 2020.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Effective January 1, 2020, the Company adopted the requirements of the ASU on the measurement of credit losses on certain financial instruments following a modified retrospective approach, as further discussed in Note 2. As such, results for reporting periods beginning on January&#160;1, 2020, are presented under the new guidance, while prior period amounts are not adjusted and continue to be reported in accordance with historic accounting.

Estimates are used for items such as long-lived assets and goodwill; fair values of acquired assets and liabilities under the acquisition method of accounting; aggregate reserves; property depreciable lives; tax provisions; revenue recognized using the cost-to-cost measure of progress for contracts; expected credit losses; environmental and other loss contingencies; regulatory assets expected to be recovered in rates charged to customers; costs on construction contracts; unbilled revenues; actuarially determined benefit costs; asset retirement obligations; lease classification; present value of right-of-use assets and lease liabilities; and the valuation of stock-based compensation. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised. Consequently, operating results can be affected by revisions to prior accounting estimates.&lt;/span&gt;&lt;/div&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

The Company evaluated the impact of the out-of-period adjustment, individually and in the aggregate with the previously mentioned out-of-period adjustment, and concluded it was not material to any previously issued interim and annual consolidated financial statements and the adjustment was not material to the three and twelve months ended December&#160;31, 2020.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Effective January 1, 2020, the Company adopted the requirements of the ASU on the measurement of credit losses on certain financial instruments following a modified retrospective approach, as further discussed in Note 2.

The guidance introduced a new impairment model known as the current expected credit loss model that replaced the incurred loss impairment methodology previously included under GAAP. This guidance required entities to present certain investments in debt securities, trade accounts receivable and other financial assets at their net carrying value of the amount expected to be collected on the financial statements. The Company adopted the guidance on January&#160;1, 2020, using a modified retrospective approach.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company formed an implementation team to review and assess existing financial assets to identify and evaluate the financial assets subject to the new current expected credit loss model. The Company assessed the impact of the guidance on its processes and internal controls and has identified and updated existing internal controls and processes to ensure compliance with the new guidance; such modifications were deemed insignificant. During the assessment phase, the Company identified the complete portfolio of assets subject to the current expected credit loss model. The Company determined the guidance did not have a material impact on its results of operations, financial position, cash flows or disclosures and did not record a material cumulative effect adjustment upon adoption. See Receivables and allowance for expected credit losses within this note for additional information on the Company's expected credit losses. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%"&gt;ASU 2018-13 - Changes to the Disclosure Requirements for Fair Value Measurement&lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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 modified, among other things, the disclosures required for Level 3 fair value measurements, including the range and weighted average of significant unobservable inputs. The guidance removed, among other things, the disclosure requirement to disclose transfers between Levels 1 and 2. The Company adopted the guidance on January&#160;1, 2020, and determined it did not have a material impact on its disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:9.5pt;font-weight:700;line-height:140%"&gt;Recently issued accounting standards not yet adopted&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%"&gt;ASU 2018-14 - Changes to the Disclosure Requirements for Defined Benefit Plans&lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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 removed disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and added disclosure requirements identified as relevant. The guidance added, 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 removed, 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 was effective for the Company on January&#160;1, 2021, and must be applied on a retrospective basis. The Company determined the new guidance will not materially impact its consolidated financial statement disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%"&gt;ASU 2019-12 - Simplifying the Accounting for Income Taxes&lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt; In December&#160;2019, the FASB issued guidance on simplifying the accounting for income taxes by removing certain exceptions in ASC 740 and providing simplification amendments. The guidance removed exceptions on intraperiod tax allocations and reporting and provided simplification on accounting for franchise taxes, tax basis goodwill and tax law changes. The Company adopted the guidance on January&#160;1, 2021, and determined it did not have a material impact on its results of operations, financial position, cash flows and disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%"&gt;ASU 2020-04 - Reference Rate Reform&lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt; In March 2020, the FASB issued optional guidance to ease the facilitation of the effects of reference rate reform on financial reporting. The guidance applies to certain contract modifications, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. LIBOR is expected to be retired with a full phase-out by the end of 2021 and replaced by new reference rates, which includes SOFR. The guidance can be applied beginning in the interim period that includes March 12, 2020, and cannot be applied to contract modifications or hedging relationships entered into or evaluated after December 31, 2022. The Company has updated its credit agreements to include language regarding the successor or alternate rate to LIBOR, and a review of other contracts and agreements is on-going. The Company does not expect the guidance to have a material impact on its results of operations, financial position, cash flows or disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Cash and cash equivalents&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Revenue recognition&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;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.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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 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 30 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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The pipeline 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 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, 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 12 days of receipt of the invoice. For gathering contracts not governed by the tariff, amounts are due within 20 days of invoice receipt. For other contracts not governed by the tariff, payment terms are net 30 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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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 an input method based on the cost-to-cost measure of progress on a project. This 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 30 days of receipt. There are no material obligations for returns, refunds or other similar obligations.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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 expects to record adjustments as it accumulates the information needed to estimate the fair value of assets acquired and liabilities assumed, including working capital balances, estimated fair value of identifiable intangible assets, property, plant and equipment, total consideration and goodwill. The excess of the purchase price over the aggregate fair values is recorded as goodwill. The Company calculated the fair value of the assets acquired in 2020 and 2019 using a market or cost approach (or a combination of both). 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 final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill, and will be made as soon as practical, but no later than 12 months from the respective acquisition dates. Any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Receivables and allowance for expected credit losses&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Receivable consists primarily of trade receivables from the sale of goods and services, which are recorded at the invoiced amount, and contract assets, net of expected credit losses. For more information on contract assets, see Note&#160;3. The Company's trade receivables are all due in 12 months or less. The total balance of receivables past due 90 days or more was $43.9 million and $46.7 million at December&#160;31, 2020 and 2019, respectively. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company's expected credit losses are determined through a review using historical credit loss experience, changes in asset specific characteristics, current conditions and reasonable and supportable future forecasts, among other specific account data, and is performed at least quarterly. The Company develops and documents its methodology to determine its allowance for expected credit losses at each of its reportable business segments. Risk characteristics used by the business segments may include customer mix, knowledge of customers and general economic conditions of the various local economies, among others. Specific account balances are written off when management determines the amounts to be uncollectible. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company conducted additional analysis of its receivables and allowance for expected credit losses due to the impacts of COVID-19. As more customer balances enter arrears, further analysis supported increasing the uncollectible factors used in determining the expected credit losses of certain segments during 2020. Management has reviewed the balance reserved through the allowance for expected credit losses and believes it is reasonable. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span

When regulated assets are retired, or otherwise disposed of in the ordinary course of business, the original cost of the asset is charged to accumulated depreciation.

The Company collects removal costs for plant assets in regulated utility rates. These amounts are recorded as regulatory liabilities on the Consolidated Balance Sheets. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:8pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Impairment of long-lived assets&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company reviews the carrying values of its long-lived assets, excluding goodwill, whenever events or changes in circumstances indicate that such carrying values may not be recoverable. The determination of whether an impairment has occurred is based on an estimate of undiscounted future cash flows attributable to the assets, compared to the carrying value of the assets. If impairment has occurred, the amount of the impairment recognized is determined by estimating the fair value of the assets and recording a loss if the carrying value is greater than the fair value. The impairments are recorded in operation and maintenance expense on the Consolidated Statements of Income.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;No significant impairment losses were recorded in 2020, 2019 or 2018. Unforeseen events and changes in circumstances could require the recognition of impairment losses at some future date.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Regulatory assets and liabilities&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company's regulated businesses are subject to various state and federal agency regulations. The accounting policies followed by these businesses are generally subject to the Uniform System of Accounts of the FERC as well as the provisions of ASC 980 - &lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:400;line-height:140%"&gt;Regulated Operations&lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;. These accounting policies differ in some respects from those used by the Company's non-regulated businesses.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company's regulated businesses account for certain income and expense items under the provisions of regulatory accounting, which requires these businesses to defer as regulatory assets or liabilities certain items that would have otherwise been reflected as expense or income, respectively. The Company records regulatory assets or liabilities at the time the Company determines the amounts to be recoverable in current or future rates. Regulatory assets and liabilities are being amortized consistently with the regulatory treatment established by the FERC and the applicable state public service commission. See Note&#160;6 for more information regarding the nature and amounts of these regulatory deferrals.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Natural gas costs recoverable or refundable through rate adjustments&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Under the terms of certain orders of the applicable state public service commissions, the Company is deferring natural gas commodity, transportation and storage costs that are greater or less than amounts presently being recovered through its existing rate schedules. Such orders generally provide that these amounts are recoverable or refundable through rate adjustments. Natural gas costs refundable through rate adjustments were $18.6&#160;million and $23.8&#160;million at December&#160;31, 2020 and 2019, respectively, which was included in regulatory liabilities due within one year on the Consolidated Balance Sheets. Natural gas costs recoverable through rate adjustments were $64.0&#160;million and $89.2&#160;million at December&#160;31, 2020 and 2019, respectively, which was included in current regulatory assets and noncurrent assets - regulatory assets on the Consolidated Balance Sheets.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Goodwill&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Goodwill represents the excess of the purchase price over the fair value of identifiable net tangible and intangible assets acquired in a business combination. Goodwill is required to be tested for impairment annually, which the Company completes in the fourth quarter, or more frequently if events or changes in circumstances indicate that goodwill may be impaired.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company has determined that the reporting units for its goodwill impairment test are its operating segments, or components of an operating segment, that constitute a business for which discrete financial information is available and for which segment management regularly reviews the operating results. For more information on the Company's operating segments, see Note&#160;17. Goodwill impairment, if any, is measured by comparing the fair value of each reporting unit to its carrying value. If the fair value of a reporting unit exceeds its carrying value, the goodwill of the reporting unit is not impaired. If the carrying value of a reporting unit exceeds its fair value, the Company must record an impairment loss for the amount that the carrying value of the reporting unit, including goodwill, exceeds the fair value of the reporting unit. For the years ended December&#160;31, 2020, 2019 and 2018, there were no impairment losses recorded. The Company performed its annual goodwill impairment test in the fourth quarter of 2020 and determined the fair value substantially exceeded the carrying value at all reporting units at October&#160;31, 2020.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Investments&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company's investments include the cash surrender value of life insurance policies, an insurance contract, mortgage-backed securities and U.S. Treasury securities. The Company measures its investment in the insurance contract at fair value with any unrealized gains and losses recorded on the Consolidated Statements of Income. The Company has not elected the fair value option for its mortgage-backed securities and U.S. Treasury securities and, as a result, the unrealized gains and losses on these investments are recorded in accumulated other comprehensive income (loss). For more information, see Notes&#160;8 and 18.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Derivative instruments&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company enters into commodity price derivative contracts in order to minimize the price volatility associated with natural gas costs at its natural gas distribution segment. These derivatives are not designated as hedging instruments and are recorded in the Consolidated Balance Sheets at fair value, as discussed in Note 8. Changes in the fair value of these derivatives along with any contract settlements are recorded each period in regulatory assets or liabilities in accordance with regulatory accounting. The Company does not enter into any derivatives for trading or other speculative purposes.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;In 2017, the WUTC issued a requirement for gas providers to implement robust, risk-responsive hedging programs in order to minimize volatility in natural gas prices for natural gas utility customers and in 2019, the Company implemented policies and procedures that met these requirements. During 2020 and 2019, the Company entered into commodity price derivative contracts securing the purchase of 1.4 million MMBtu and 535,000 MMBtu of natural gas, respectively.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Leases&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. The Company recognizes leases with an original lease term of 12 months or less in income on a straight-line basis over the term of the lease and does not recognize a corresponding right-of-use asset or lease liability. The Company determines the lease term based on the non-cancelable and cancelable periods in each contract. The non-cancelable period consists of the term of the contract that is legally enforceable and cannot be canceled by either party without incurring a significant penalty. The cancelable period is determined by various factors that are based on who has the right to cancel a contract. If only the lessor has the right to cancel the contract, the Company will assume the contract will continue. If the lessee is the only party that has the right to cancel the contract, the Company looks to asset, entity and market-based factors. If both the lessor and the lessee have the right to cancel the contract, the Company assumes the contract will not continue. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The discount rate used to calculate the present value of the lease liabilities is based upon the implied rate within each contract. If the rate is unknown or cannot be determined, the Company uses an incremental borrowing rate, which is determined by the length of the contract, asset class and the Company's borrowing rates, as of the commencement date of the contract.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Asset retirement obligations&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company records the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When the liability is initially recorded, the Company capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, the Company either settles the obligation for the recorded amount or incurs a gain or loss at its non-regulated operations or incurs a regulatory asset or liability at its regulated operations.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Stock-based compensation&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company determines compensation expense for stock-based awards based on the estimated fair values at the grant date and recognizes the related compensation expense over the vesting period. The Company uses the straight-line amortization method to recognize compensation expense related to restricted stock, which only has a service condition. This method recognizes stock compensation expense on a straight-line basis over the requisite service period for the entire award. The Company recognizes compensation expense related to performance awards that vest based on performance metrics and service conditions on a straight-line basis over the service period. Inception-to-date expense is adjusted based upon the determination of the potential achievement of the performance target at each reporting date. The Company recognizes compensation expense related to performance awards with market-based performance metrics on a straight-line basis over the requisite service period.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company records the compensation expense for performance share awards using an estimated forfeiture rate. The estimated forfeiture rate is calculated based on an average of actual historical forfeitures. The Company also performs an analysis of any known factors at the time of the calculation to identify any necessary adjustments to the average historical forfeiture rate. At the time actual forfeitures become more than estimated forfeitures, the Company records compensation expense using actual forfeitures.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Earnings per share&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Basic earnings per share were computed by dividing net income by the weighted average number of shares of common stock outstanding during the year. Diluted earnings per share were computed by dividing net income by the total of the weighted average number of shares of common stock outstanding during the year, plus the effect of nonvested performance share awards and restricted stock units. Common stock outstanding includes issued shares less shares held in treasury. Net income was the same for both the basic and diluted earnings per share calculations. A reconciliation of the weighted average common shares outstanding used in the basic and diluted earnings per share calculation was as follows:&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:5pt;margin-top:5pt"&gt;&lt;table style="border-collapse:collapse;display:inline-table;vertical-align:top;width:381.00pt"&gt;&lt;tr&gt;&lt;td style="width:1.0pt"/&gt;&lt;td style="width:228.25pt"/&gt;&lt;td style="width:1.0pt"/&gt;&lt;td style="width:1.0pt"/&gt;&lt;td style="width:48.25pt"/&gt;&lt;td style="width:1.0pt"/&gt;&lt;td style="width:1.0pt"/&gt;&lt;td style="width:48.25pt"/&gt;&lt;td style="width:1.0pt"/&gt;&lt;td style="width:1.0pt"/&gt;&lt;td style="width:48.25pt"/&gt;&lt;td style="width:1.0pt"/&gt;&lt;/tr&gt;&lt;tr style="height:12pt"&gt;&lt;td colspan="3" style="padding:0 1pt"/&gt;&lt;td colspan="2" style="padding:2px 0 2px 1pt;text-align:right;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:7pt;font-weight:700;line-height:100%"&gt;2020&lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:7pt;font-weight:400;line-height:100%"&gt;&#160;&lt;/span&gt;&lt;/td&gt;&lt;td style="padding:2px 1pt 2px 0;text-align:right;vertical-align:bottom"/&gt;&lt;td colspan="2" style="border-bottom:1pt solid #000000;padding:2px 0 2px 1pt;text-align:right;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:400;line-height:100%"&gt;2019&#160;&lt;/span&gt;&lt;/td&gt;&lt;td style="border-bottom:1pt solid #000000;padding:2px 1pt 2px 0;text-align:right;vertical-align:bottom"/&gt;&lt;td colspan="2" style="border-bottom:1pt solid #000000;padding:2px 0 2px 1pt;text-align:right;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:400;line-height:100%"&gt;2018&#160;&lt;/span&gt;&lt;/td&gt;&lt;td style="border-bottom:1pt solid #000000;padding:2px 1pt 2px 0;text-align:right;vertical-align:bottom"/&gt;&lt;/tr&gt;&lt;tr style="height:12pt"&gt;&lt;td colspan="3" style="border-top:1pt solid #000000;padding:0 1pt"/&gt;&lt;td colspan="9" style="border-top:1pt solid #000000;padding:2px 1pt;text-align:center;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:400;line-height:100%"&gt;(In thousands)&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr style="height:12pt"&gt;&lt;td colspan="3" style="background-color:#cceeff;padding:2px 1pt;text-align:left;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:7pt;font-weight:400;line-height:100%"&gt;Weighted average common shares outstanding -

A variable interest holder that consolidates the VIE is called the primary beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE's assets, liabilities and noncontrolling interests at fair value and subsequently account for the VIE as if it were consolidated.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:11pt;margin-top:11pt;text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company's evaluation of whether it qualifies as the primary beneficiary of a VIE involves significant judgments, estimates and assumptions and includes a qualitative analysis of the activities that most significantly impact the VIE's economic performance and whether the Company has the power to direct those activities, the design of the entity, the rights of the parties and the purpose of the arrangement.&lt;/span&gt;&lt;/div&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

The guidance introduced a new impairment model known as the current expected credit loss model that replaced the incurred loss impairment methodology previously included under GAAP. This guidance required entities to present certain investments in debt securities, trade accounts receivable and other financial assets at their net carrying value of the amount expected to be collected on the financial statements. The Company adopted the guidance on January&#160;1, 2020, using a modified retrospective approach.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company formed an implementation team to review and assess existing financial assets to identify and evaluate the financial assets subject to the new current expected credit loss model. The Company assessed the impact of the guidance on its processes and internal controls and has identified and updated existing internal controls and processes to ensure compliance with the new guidance; such modifications were deemed insignificant. During the assessment phase, the Company identified the complete portfolio of assets subject to the current expected credit loss model. The Company determined the guidance did not have a material impact on its results of operations, financial position, cash flows or disclosures and did not record a material cumulative effect adjustment upon adoption. See Receivables and allowance for expected credit losses within this note for additional information on the Company's expected credit losses. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%"&gt;ASU 2018-13 - Changes to the Disclosure Requirements for Fair Value Measurement&lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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 modified, among other things, the disclosures required for Level 3 fair value measurements, including the range and weighted average of significant unobservable inputs. The guidance removed, among other things, the disclosure requirement to disclose transfers between Levels 1 and 2. The Company adopted the guidance on January&#160;1, 2020, and determined it did not have a material impact on its disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:9.5pt;font-weight:700;line-height:140%"&gt;Recently issued accounting standards not yet adopted&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%"&gt;ASU 2018-14 - Changes to the Disclosure Requirements for Defined Benefit Plans&lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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 removed disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and added disclosure requirements identified as relevant. The guidance added, 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 removed, 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 was effective for the Company on January&#160;1, 2021, and must be applied on a retrospective basis. The Company determined the new guidance will not materially impact its consolidated financial statement disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%"&gt;ASU 2019-12 - Simplifying the Accounting for Income Taxes&lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt; In December&#160;2019, the FASB issued guidance on simplifying the accounting for income taxes by removing certain exceptions in ASC 740 and providing simplification amendments. The guidance removed exceptions on intraperiod tax allocations and reporting and provided simplification on accounting for franchise taxes, tax basis goodwill and tax law changes. The Company adopted the guidance on January&#160;1, 2021, and determined it did not have a material impact on its results of operations, financial position, cash flows and disclosures.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%"&gt;ASU 2020-04 - Reference Rate Reform&lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt; In March 2020, the FASB issued optional guidance to ease the facilitation of the effects of reference rate reform on financial reporting. The guidance applies to certain contract modifications, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. LIBOR is expected to be retired with a full phase-out by the end of 2021 and replaced by new reference rates, which includes SOFR. The guidance can be applied beginning in the interim period that includes March 12, 2020, and cannot be applied to contract modifications or hedging relationships entered into or evaluated after December 31, 2022. The Company has updated its credit agreements to include language regarding the successor or alternate rate to LIBOR, and a review of other contracts and agreements is on-going. The Company does not expect the guidance to have a material impact on its results of operations, financial position, cash flows or disclosures.&lt;/span&gt;&lt;/div&gt;</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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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 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 30 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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The pipeline 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 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, 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 12 days of receipt of the invoice. For gathering contracts not governed by the tariff, amounts are due within 20 days of invoice receipt. For other contracts not governed by the tariff, payment terms are net 30 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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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 an input method based on the cost-to-cost measure of progress on a project. This 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 30 days of receipt. There are no material obligations for returns, refunds or other similar obligations.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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 Company expects to record adjustments as it accumulates the information needed to estimate the fair value of assets acquired and liabilities assumed, including working capital balances, estimated fair value of identifiable intangible assets, property, plant and equipment, total consideration and goodwill. The excess of the purchase price over the aggregate fair values is recorded as goodwill. The Company calculated the fair value of the assets acquired in 2020 and 2019 using a market or cost approach (or a combination of both). 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 final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill, and will be made as soon as practical, but no later than 12 months from the respective acquisition dates. Any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations.</us-gaap:BusinessCombinationsPolicy>

The Company recognizes leases with an original lease term of 12 months or less in income on a straight-line basis over the term of the lease and does not recognize a corresponding right-of-use asset or lease liability. The Company determines the lease term based on the non-cancelable and cancelable periods in each contract. The non-cancelable period consists of the term of the contract that is legally enforceable and cannot be canceled by either party without incurring a significant penalty. The cancelable period is determined by various factors that are based on who has the right to cancel a contract. If only the lessor has the right to cancel the contract, the Company will assume the contract will continue. If the lessee is the only party that has the right to cancel the contract, the Company looks to asset, entity and market-based factors. If both the lessor and the lessee have the right to cancel the contract, the Company assumes the contract will not continue. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The discount rate used to calculate the present value of the lease liabilities is based upon the implied rate within each contract. If the rate is unknown or cannot be determined, the Company uses an incremental borrowing rate, which is determined by the length of the contract, asset class and the Company's borrowing rates, as of the commencement date of the contract.&lt;/span&gt;&lt;/div&gt;</us-gaap:LesseeLeasesPolicyTextBlock>

When the liability is initially recorded, the Company capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, the Company either settles the obligation for the recorded amount or incurs a gain or loss at its non-regulated operations or incurs a regulatory asset or liability at its regulated operations.</us-gaap:AssetRetirementObligationsPolicy>

The Company uses the straight-line amortization method to recognize compensation expense related to restricted stock, which only has a service condition. This method recognizes stock compensation expense on a straight-line basis over the requisite service period for the entire award. The Company recognizes compensation expense related to performance awards that vest based on performance metrics and service conditions on a straight-line basis over the service period. Inception-to-date expense is adjusted based upon the determination of the potential achievement of the performance target at each reporting date. The Company recognizes compensation expense related to performance awards with market-based performance metrics on a straight-line basis over the requisite service period.The Company records the compensation expense for performance share awards using an estimated forfeiture rate. The estimated forfeiture rate is calculated based on an average of actual historical forfeitures. The Company also performs an analysis of any known factors at the time of the calculation to identify any necessary adjustments to the average historical forfeiture rate. At the time actual forfeitures become more than estimated forfeitures, the Company records compensation expense using actual forfeitures</us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy>

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.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span

style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company recognized a net increase in revenues of $58.8&#160;million and $44.1&#160;million for the years ended December&#160;31, 2020 and 2019, respectively, from performance obligations satisfied in prior periods.&lt;/span&gt;&lt;/div&gt;&lt;div

obligations, also referred to as backlog, at the construction materials and contracting and construction services segments include unrecognized revenues that the Company reasonably expects to be realized. These unrecognized revenues can include: projects that have a written award, a letter of intent, a notice to proceed, an agreed upon work order to perform work on mutually accepted terms and conditions and change orders or claims to the extent management believes additional contract revenues will be earned and are deemed probable of collection. Excluded from remaining performance obligations are potential orders under master service agreements. The majority of the Company's construction contracts have an original duration of less than two years. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The remaining performance obligations at the pipeline segment include firm transportation and storage contracts with fixed pricing and fixed volumes. The Company has applied the practical expedient that does not require additional disclosures for contracts with an original duration of less than 12 months to certain firm transportation and non-regulated contracts. The Company's firm transportation and firm storage contracts included in the remaining performance obligations have weighted average remaining durations of approximately five and one years, respectively. &lt;/span&gt;&lt;/div&gt;At December&#160;31, 2020, the Company's remaining performance obligations were $2.1&#160;billion. The Company expects to recognize the following revenue amounts in future periods related to these remaining performance obligations: $1.6&#160;billion within the next 12&#160;months or less; $298.8&#160;million within the next 13 to 24 months; and $234.3&#160;million in 25 months or more.</us-gaap:RevenueFromContractWithCustomerTextBlock>

These assets are largely comprised of the unfunded portion of pension and postretirement benefits, asset retirement obligations, accelerated depreciation on plant to be retired and the estimated future cost of manufactured gas plant site remediation.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:8pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;In 2019, the Company experienced increased natural gas costs in Washington from the rupture of the Enbridge pipeline in Canada in late 2018.

The Company has accelerated the depreciation related to these facilities in property, plant and equipment and has recorded the difference between the accelerated depreciation, in accordance with GAAP, and the depreciation approved for rate-making purposes as regulatory assets. The Company expects to recover the regulatory assets related to the plants to be retired in future rates. &lt;/span&gt;&lt;/div&gt;If, for any reason, the Company's regulated businesses cease to meet the criteria for application of regulatory accounting for all or part of their operations, the regulatory assets and liabilities relating to those portions ceasing to meet such criteria would be removed from the balance sheet and included in the statement of income or accumulated other comprehensive income (loss) in the period in which the discontinuance of regulatory accounting occurs.</us-gaap:ScheduleOfRegulatoryAssetsAndLiabilitiesTextBlock>

The Company anticipates using these investments, which consist of an insurance contract, to satisfy its obligations under its unfunded, nonqualified defined benefit plans for executive officers and certain key management employees, and invests in these fixed-income and equity securities for the purpose of earning investment returns and capital appreciation. These investments, which totaled $100.1&#160;million and $87.0&#160;million at December&#160;31, 2020 and 2019, respectively, are classified as investments on the Consolidated Balance Sheets. The net unrealized gains on these investments for the years ended December&#160;31, 2020 and 2019, were $13.1&#160;million and $13.2&#160;million, respectively. The net unrealized loss on these investments for the year ended December 31, 2018, was $3.6&#160;million. The change in fair value, which is considered part of the cost of the plan, is classified in other income on the Consolidated Statements of Income. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company did not elect the fair value option, which records gains and losses in income, for its available-for-sale securities, which include mortgage-backed securities and U.S. Treasury securities.

The estimated fair value of the Company's 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 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 Company has paid quarterly dividends for 83 consecutive years with an increase in the dividend amount for the last 30 consecutive years. For the years ended December&#160;31, 2020, 2019 and 2018, dividends declared on common stock were $.8350, $.8150 and $.7950 per common share, respectively. Dividends on common stock are paid quarterly to the stockholders of record less than 30 days prior to the distribution date. For the years ended December&#160;31, 2020, 2019 and 2018, the dividends declared to common stockholders were $167.4&#160;million, $162.1&#160;million and $155.7&#160;million, respectively.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The declaration and payment of dividends of the Company is at the sole discretion of the board of directors. In addition, the Company's subsidiaries are generally restricted to paying dividends out of capital accounts or net assets. The following discusses the most restrictive limitations.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Pursuant to a covenant under a credit agreement, Centennial may only declare or pay distributions if, as of the last day of any fiscal quarter, the ratio of Centennial's average consolidated indebtedness as of the last day of such fiscal quarter and each of the preceding three fiscal quarters to Centennial's Consolidated EBITDA does not exceed 3.5 to 1. In addition, certain credit agreements and regulatory limitations of the Company's subsidiaries also contain restrictions on dividend payments. The most restrictive limitation requires the Company's subsidiaries not to permit the ratio of funded debt to capitalization to be greater than 65&#160;percent. Based on this limitation, approximately $1.4&#160;billion of the net assets of the Company's subsidiaries, which represents common stockholders' equity including retained earnings, would be restricted from use for dividend payments at December&#160;31, 2020. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company currently has a shelf registration statement on file with the SEC, under which the Company may issue and sell any combination of common stock and debt securities. The Company may sell such securities if warranted by market conditions and the Company's capital requirements. Any public offer and sale of such securities will be made only by means of a prospectus meeting the requirements of the Securities Act and the rules and regulations thereunder.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;In August 2020, the Company amended the Distribution Agreement dated February 22, 2019, with J.P. Morgan Securities LLC and MUFG Securities Americas Inc., as sales agents. The Distribution Agreement allows the offering, issuance and sale of up to 6.4 million shares of the Company's common stock in connection with an &#x201c;at-the-market&#x201d; offering. The common stock may be offered for sale, from time to time, in accordance with the terms and conditions of the agreement. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company did not issue shares of common stock for the year ended December&#160;31, 2020, pursuant to the &#x201c;at-the-market&#x201d; offering. The Company issued 3.6&#160;million shares of common stock for the year ended December&#160;31, 2019, pursuant to the "at-the-market" offering. For the year ended December&#160;31, 2019, the Company received net proceeds of $94.0 million and paid commissions to the sales agents of approximately $950,000 in connection with the sales of common stock under the "at-the-market" offering. The net proceeds were used for capital expenditures and acquisitions. As of December&#160;31, 2020, the Company had capacity to issue up to 6.4 million additional shares of common stock under the "at-the-market" offering program.&lt;/span&gt;&lt;/div&gt;The K-Plan provides participants the option to invest in the Company's common stock. For the years ended December&#160;31, 2020, 2019 and 2018, the K-Plan purchased shares of common stock on the open market or issued original issue common stock of the Company. At December&#160;31, 2020, there were 7.2&#160;million shares of common stock reserved for original issuance under the K-Plan. The Company currently has 2.0&#160;million shares of preferred stock authorized to be issued with a $100 par value. At December&#160;31, 2020 and 2019, there were no shares outstanding.</us-gaap:StockholdersEquityNoteDisclosureTextBlock>

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 Company's operations are located within the United States.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The pipeline segment provides natural gas transportation and underground storage services through a regulated pipeline system primarily in the Rocky Mountain and northern Great Plains regions of the United States. This segment also provides non-regulated cathodic protection and other energy-related services. In 2020, the pipeline segment divested its regulated and non-regulated natural gas gathering assets. With the completion of these sales, the segment has exited the natural gas gathering business.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The construction materials and contracting segment mines, processes and sells construction aggregates (crushed stone, sand and gravel); produces and sells asphalt mix; and supplies 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, including Alaska and Hawaii.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The construction services segment provides inside and outside specialty contracting services in 44 states plus Washington D.C. Its inside services include design, construction and maintenance of electrical and communication wiring and infrastructure, fire suppression systems, and mechanical piping and 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. This segment also constructs and maintains renewable energy projects. These specialty contracting services are provided to utilities and large manufacturing, commercial, industrial, institutional and governmental customers. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Other category includes the activities of Centennial Capital, which, through its subsidiary InterSource Insurance Company, 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. In addition, the Other category includes certain assets, liabilities and tax adjustments of the holding company primarily associated with corporate functions and 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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Discontinued operations include the results and supporting activities of Dakota Prairie Refining and Fidelity other than certain general and administrative costs and interest expense as described above.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The information below follows the same accounting policies as described in Note 2.

The Company uses a measurement date of December&#160;31 for all of its pension and postretirement benefit plans.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Prior to 2013, defined benefit pension plan benefits and accruals for all nonunion and certain union plans were frozen and on June&#160;30, 2015, the remaining union plan was frozen. These employees were eligible to receive additional defined contribution plan benefits. In October 2018, the Company transferred the liability of certain participants in the defined benefit pension plan, who are currently receiving benefits, to an annuity company. The transfer of the benefit payments for these participants reduced the Company's liability and future premiums. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Effective January&#160;1, 2010, eligibility to receive retiree medical benefits was modified at certain of the Company's businesses. Employees who had attained age 55 with 10 years of continuous service by December&#160;31, 2010, were provided the option to choose between a pre-65 comprehensive medical plan coupled with a Medicare supplement or a specified company funded Retiree Reimbursement Account, regardless of when they retire. All other eligible employees must meet the new eligibility criteria of age 60 and 10 years of continuous service at the time they retire to be eligible for a specified company funded Retiree Reimbursement Account. Employees hired after December&#160;31, 2009, will not be eligible for retiree medical benefits at certain of the Company's businesses.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;In 2012, the Company modified health care coverage for certain retirees. Effective January&#160;1, 2013, post-65 coverage was replaced by a fixed-dollar subsidy for retirees and spouses to be used to purchase individual insurance through an

The Company's investment policy with respect to pension and other postretirement assets is to make investments solely in the interest of the participants and beneficiaries of the plans and for the exclusive purpose of providing benefits accrued and defraying the reasonable expenses of administration. The Company strives to maintain investment diversification to assist in minimizing the risk of large losses. The Company's policy guidelines allow for investment of funds in cash equivalents, fixed-income securities and equity securities. The guidelines prohibit investment in commodities and futures contracts, equity private placement, employer securities, leveraged or derivative securities, options, direct real estate investments, precious metals, venture capital and limited partnerships. The guidelines also prohibit short selling and margin transactions.

The estimated fair value of the pension plans' Level&#160;2 corporate and municipal bonds is determined using other observable inputs, including benchmark yields, reported trades, broker/dealer quotes, bids, offers, future cash flows and other reference data. The estimated fair value of the pension plans' Level&#160;1 U.S. Government securities are valued based on quoted prices on an active market. The estimated fair value of the pension plans' Level&#160;2 U.S. Government securities are valued mainly using other observable inputs, including benchmark yields, reported trades, broker/dealer quotes, bids, offers, to be announced prices, future cash flows and other reference data. Some of these securities are valued using pricing from outside sources.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;All investments measured at net asset value in the tables that follow are invested in comingled funds, separate accounts or common collective trusts which do not have publicly quoted prices. The fair value of the comingled funds, separate accounts and common collective trusts are determined based on the net asset value of the underlying investments. The fair value of the underlying investments held by the comingled funds, separate accounts and common collective trusts is generally based on quoted prices in active

The Company files for rate adjustments to seek recovery of operating costs and capital investments, as well as reasonable returns as allowed by regulators. Certain regulatory proceedings and cases may also contain recurring mechanisms that can have an annual true-up. Examples of these recurring mechanisms include: infrastructure riders, transmission trackers, renewable resource cost adjustment riders, as well as weather normalization and decoupling mechanisms. The following paragraphs summarize the Company's significant regulatory proceedings and cases by jurisdiction, including the status of each open request. The Company is unable to predict the ultimate outcome of these matters, the timing of final decisions of the various regulators and courts, or the effect on the Company's results of operations, financial position or cash flows.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:400;line-height:140%"&gt;MNPUC&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;On September&#160;27, 2019, Great Plains filed an application with the MNPUC for a natural gas rate increase of approximately $2.9&#160;million annually or approximately 12.0&#160;percent above current rates. The requested increase was primarily to recover investments in facilities to enhance safety and reliability and the depreciation and taxes associated with the increase in investment. On November&#160;22, 2019, Great Plains received approval to implement an interim rate increase of approximately $2.6&#160;million or approximately 11.0&#160;percent, subject to refund, effective January&#160;1, 2020. On October&#160;26, 2020, the MNPUC issued an order authorizing an annual increase in revenues of approximately $2.6&#160;million or approximately 11.5&#160;percent. This matter is pending before the MNPUC.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:400;line-height:140%"&gt;MTPSC&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;On May&#160;8, 2020, Montana-Dakota filed a request with the MTPSC to use deferred accounting for costs related to the COVID-19 pandemic.

The requested increase was primarily to recover investments in facilities that were made to enhance system safety and reliability, as well as the depreciation, taxes and operation and maintenance costs associated with this increase in investment.

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)&#160;the matter involves novel or unsettled legal theories.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;At December&#160;31, 2020 and 2019, the Company accrued liabilities which have not been discounted, including liabilities held for sale, of $41.5&#160;million and $29.1&#160;million, respectively. At December&#160;31, 2020 and 2019, the Company also recorded corresponding insurance receivables of $17.5&#160;million and $16.2&#160;million, respectively, and regulatory assets of $21.3&#160;million and $10.5&#160;million, respectively, related to the accrued liabilities. The accruals are for contingencies, including litigation, production taxes, royalty claims and environmental matters. 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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Environmental matters&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%"&gt;Portland Harbor Site &lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;In December 2000, Knife River&#160;- Northwest was named by the EPA as a PRP in connection with the cleanup of the riverbed site adjacent to a commercial property site acquired by Knife River&#160;- Northwest from Georgia-Pacific West, Inc. along the Willamette River. The riverbed site is part of the Portland, Oregon, Harbor Superfund Site where the EPA wants responsible parties to share in the costs of cleanup. 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. Investigative costs are indicated to be in excess of $100&#160;million. The EPA issued an ROD in January 2017 adopting a selected remedy which is expected to take 13 years to complete with a then estimated present value of approximately $1 billion. Corrective action will not be taken until remedial design/remedial action plans are approved by the EPA. Knife River&#160;- Northwest was also notified 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. 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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;At this time, Knife River&#160;- Northwest does not believe it is a responsible party and 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. LWG has 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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%"&gt;Manufactured Gas Plant Sites &lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Claims have been made against Cascade for cleanup of environmental contamination at manufactured gas plant sites operated by Cascade's predecessors and a similar claim has been made against Montana-Dakota for a site operated by Montana-Dakota and its predecessors. Any accruals related to these claims are reflected in regulatory assets. For more information, see Note&#160;6.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Demand has been made of Montana-Dakota to participate in investigation and remediation of environmental contamination at a site in Missoula, Montana. The site operated as a former manufactured gas plant from approximately 1907 to 1938 when it was converted to a butane-air plant that operated until 1956. Montana-Dakota or its predecessors owned or controlled the site for a period of the time it operated as a manufactured&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:9pt;font-weight:400;line-height:140%"&gt; &lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;gas plant and Montana-Dakota operated the butane-air plant from 1940 to 1951, at which time it sold the plant. There are no documented wastes or by-products resulting from the mixing or distribution of butane-air gas. Preliminary assessment of a portion of the site provided a recommended remedial alternative for that portion of approximately $560,000. However, the recommended remediation would not address any potential contamination to adjacent parcels that may be impacted by contamination from the manufactured gas plant. An environmental assessment was started in 2020, which is estimated to cost approximately $800,000. Montana-Dakota and another party agreed to voluntarily investigate and remediate the site and that Montana-Dakota will pay two-thirds of the costs for further investigation and remediation of the site. Montana-Dakota has accrued costs of $800,000 for the remediation and investigation costs, and has incurred costs of $130,000 as of December&#160;31, 2020. Montana-Dakota received notice from a prior insurance carrier that it will participate in payment of defense costs incurred in relation to the claim. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;A claim was made against Cascade 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 confirmed that contaminants have affected soil and groundwater at the site, as well as sediments in the adjacent Port Washington Narrows. 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 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 $7.6&#160;million of which $5.0&#160;million has been incurred as of December&#160;31, 2020. Based on the site investigation, preliminary remediation alternative costs were provided by consultants in August 2020; therefore, the accrual for these costs was increased in the third quarter of 2020 by $11.1&#160;million. The preliminary information received through the completion of the data report allowed for the projection of possible costs for a variety of site configurations, remedial measures and potential natural resource damage claims of between $13.6&#160;million and $71.0&#160;million. At December&#160;31, 2020, Cascade has accrued $2.6&#160;million for the remedial investigation and feasibility study, as well as $17.5&#160;million for remediation of this site. The accrual for remediation cost will be reviewed and adjusted, if necessary, after the completion of the feasibility study. In April 2010, Cascade filed a petition with the WUTC for authority to defer the 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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;A claim was made against Cascade 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 $8.0&#160;million to $20.4&#160;million with a selected preferred alternative having an estimated total cost of $9.3&#160;million. The other PRPs will develop a cleanup action plan and, after public review of the cleanup action plan, develop design documents. 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, the plant converted 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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company has received notices from and entered into agreement with certain of its insurance carriers that they will participate in defense for certain 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, the Company intends to seek recovery of remediation costs through its natural gas rates charged to customers.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%"&gt;Purchase commitments &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;The Company has entered into various commitments largely consisting of contracts for natural gas and coal supply; purchased power; natural gas transportation and storage; royalties; information technology; and construction materials.

These guarantees are related to construction contracts, insurance deductibles and loss limits, and certain other guarantees. At December&#160;31, 2020, the fixed maximum amounts guaranteed under these agreements aggregated $212.4&#160;million. Certain of the guarantees also have no fixed maximum amounts specified. The amounts of scheduled expiration of the maximum amounts guaranteed under these agreements aggregate to $178.6&#160;million in 2021; $16.1&#160;million in 2022; $7.0&#160;million in 2023; $500,000 in 2024; $500,000 in 2025; $700,000 thereafter; and $9.0&#160;million, which has no scheduled maturity date. There were no amounts outstanding under the previously mentioned guarantees at December&#160;31, 2020. In the event of default under these guarantee obligations, the subsidiary issuing the guarantee for that particular obligation would be required to make payments under its guarantee. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;Certain subsidiaries have outstanding letters of credit to third parties related to insurance policies and other agreements, some of which are guaranteed by other subsidiaries of the Company.

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.

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.

Coal purchased under the coal supply agreement is reflected in inventories on the 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="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&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;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt;At December&#160;31, 2020, 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 $33.7&#160;million.&lt;/span&gt;&lt;/div&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)&#160;the matter involves novel or unsettled legal theories.</us-gaap:CommitmentsAndContingenciesPolicyTextBlock>

The information is unconsolidated and is presented for the parent company only, MDU Resources Group, Inc. (the Company) as of and for the years ended December&#160;31, 2020 and 2019. Prior to the Holding Company Reorganization, the Company included Montana-Dakota and Great Plains, public utility divisions of the Company as of December&#160;31, 2018. On January 2, 2019, the Company announced the completion of the Holding Company Reorganization, which resulted in Montana-Dakota and Great Plains becoming a subsidiary of the Company. Immediately after consummation, the Company had, on a consolidated basis, the same assets, businesses and operations as it had immediately prior to the reorganization. For more information on the reorganization, see Item 8 - Note 1. The prior periods have not been restated and reflect the condensed financial information of Montana-Dakota and Great Plains as of and for the year ended December&#160;31, 2018. Due to the completion of the Holding Company Reorganization, the presentation of the year ended December&#160;31, 2018, will vary from that of and for the years ended December&#160;31, 2020 and 2019. In Schedule I, investments in subsidiaries are presented under the equity method of accounting where the assets and liabilities of the subsidiaries are not consolidated. The investments in net assets of the subsidiaries are recorded on the Condensed Balance Sheets. The income from subsidiaries is reported as equity in earnings of subsidiaries on the Condensed Statements of Income. The material cash inflows on the Condensed Statements of Cash Flows are primarily from the dividends and other payments received from its subsidiaries and the proceeds raised from the issuance of equity securities. The consolidated financial statements of MDU Resources Group, Inc. reflect certain businesses as discontinued operations. These statements should be read in conjunction with the consolidated financial statements and notes thereto of MDU Resources Group, Inc.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt"&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:400;line-height:140%"&gt;Earnings per common share&lt;/span&gt;&lt;span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"&gt; Please refer to the Consolidated Statements of Income of the registrant for earnings per common share.

Such costs are capitalized if they meet both of the following criteria: a. It is probable that future revenue in an amount at least equal to the capitalized cost will result from inclusion of that cost in allowable costs for rate-making purposes. b. Based on available evidence, the future revenue will be provided to permit recovery of the previously incurred cost rather than to provide for expected levels of similar future costs. If the revenue will be provided through an automatic rate-adjustment clause, this criterion requires that the regulator's intent clearly be to permit recovery of the previously incurred cost.</p></div>

The consolidated financial statements of the Company include the accounts of the following businesses: electric, natural gas distribution, pipeline, construction materials and contracting, construction services and other. The electric and natural gas distribution businesses, as well as a portion of the pipeline business, are regulated. Construction materials and contracting, construction services and the other businesses, as well as a portion of the pipeline business, are non-regulated.

The purpose of the reorganization was to make the public utility division into a subsidiary of the holding company, just as the other operating companies are wholly owned subsidiaries.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In March 2020, the World Health Organization declared the outbreak of COVID-19 a pandemic, and the President of the United States declared the COVID-19 outbreak as a national emergency. Governmental restrictions and guidelines implemented to control the spread of COVID-19 reduced commercial and interpersonal activity throughout the Company's areas of operation. Most of the Company's products and services are considered essential and accordingly operations have been generally allowed to continue. The Company has experienced some inefficiency impacts, including operation suspensions and interruptions at some locations to carry out preventive measures or in response to instances of positive tests or quarantines. The Company has assessed the impacts of the COVID-19 pandemic on its results of operations for the twelve months ended December&#160;31, 2020, and determined there were no material adverse impacts.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In the first quarter of 2020, the Company recorded an out-of-period adjustment to correct the recognition of revenue on a construction contract, which was the result of an overstatement of operating revenue and receivables of $7.7&#160;million and an understatement of operating expense and accounts payable of $1.2&#160;million in the year ended December&#160;31, 2019. This adjustment resulted in an after-tax reduction to net income of $6.7&#160;million in the first quarter of 2020. The Company evaluated the impact of the out-of-period adjustment and concluded it was not material to any previously issued interim and annual consolidated financial statements and the adjustment was not material to the three months ended March&#160;31, 2020, or the twelve months ended December&#160;31, 2020.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In the fourth quarter of 2020, the Company recorded an out-of-period adjustment to correct the recognition of net periodic benefit cost and other comprehensive income associated with the Company's benefit plans, which was the result of the previous overstatement of benefit plan expenses of $6.5&#160;million, understatement of accumulated other comprehensive loss of $2.7&#160;million and overstatement of regulatory liabilities of $3.8&#160;million from 2006 through 2020. This adjustment resulted in an after-tax increase to net income of $4.4&#160;million in the fourth quarter of 2020. The Company evaluated the impact of the out-of-period adjustment, individually and in the aggregate with the previously mentioned out-of-period adjustment, and concluded it was not material to any previously issued interim and annual consolidated financial statements and the adjustment was not material to the three and twelve months ended December&#160;31, 2020.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Effective January 1, 2020, the Company adopted the requirements of the ASU on the measurement of credit losses on certain financial instruments following a modified retrospective approach, as further discussed in Note 2. As such, results for reporting periods beginning on January&#160;1, 2020, are presented under the new guidance, while prior period amounts are not adjusted and continue to be reported in accordance with historic accounting. The Company's adoption of this guidance did not have a material impact on its financial reporting.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The assets and liabilities of the Company's discontinued operations have been classified as held for sale and are included in prepayments and other current assets, noncurrent assets - other and other accrued liabilities on the Consolidated Balance Sheets and are not material to the financial statements for any period presented.

Estimates are used for items such as long-lived assets and goodwill; fair values of acquired assets and liabilities under the acquisition method of accounting; aggregate reserves; property depreciable lives; tax provisions; revenue recognized using the cost-to-cost measure of progress for contracts; expected credit losses; environmental and other loss contingencies; regulatory assets expected to be recovered in rates charged to customers; costs on construction contracts; unbilled revenues; actuarially determined benefit costs; asset retirement obligations; lease classification; present value of right-of-use assets and lease liabilities; and the valuation of stock-based compensation. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised. Consequently, operating results can be affected by revisions to prior accounting estimates.</span></div><span></span>

The guidance introduced a new impairment model known as the current expected credit loss model that replaced the incurred loss impairment methodology previously included under GAAP. This guidance required entities to present certain investments in debt securities, trade accounts receivable and other financial assets at their net carrying value of the amount expected to be collected on the financial statements. The Company adopted the guidance on January&#160;1, 2020, using a modified retrospective approach.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company formed an implementation team to review and assess existing financial assets to identify and evaluate the financial assets subject to the new current expected credit loss model. The Company assessed the impact of the guidance on its processes and internal controls and has identified and updated existing internal controls and processes to ensure compliance with the new guidance; such modifications were deemed insignificant. During the assessment phase, the Company identified the complete portfolio of assets subject to the current expected credit loss model. The Company determined the guidance did not have a material impact on its results of operations, financial position, cash flows or disclosures and did not record a material cumulative effect adjustment upon adoption. See Receivables and allowance for expected credit losses within this note for additional information on the Company's expected credit losses. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">ASU 2018-13 - Changes to the Disclosure Requirements for Fair Value Measurement</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> 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 modified, among other things, the disclosures required for Level 3 fair value measurements, including the range and weighted average of significant unobservable inputs. The guidance removed, among other things, the disclosure requirement to disclose transfers between Levels 1 and 2. The Company adopted the guidance on January&#160;1, 2020, and determined it did not have a material impact on its disclosures.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:9.5pt;font-weight:700;line-height:140%">Recently issued accounting standards not yet adopted</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">ASU 2018-14 - Changes to the Disclosure Requirements for Defined Benefit Plans</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> 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 removed disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and added disclosure requirements identified as relevant. The guidance added, 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 removed, 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 was effective for the Company on January&#160;1, 2021, and must be applied on a retrospective basis. The Company determined the new guidance will not materially impact its consolidated financial statement disclosures.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">ASU 2019-12 - Simplifying the Accounting for Income Taxes</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> In December&#160;2019, the FASB issued guidance on simplifying the accounting for income taxes by removing certain exceptions in ASC 740 and providing simplification amendments. The guidance removed exceptions on intraperiod tax allocations and reporting and provided simplification on accounting for franchise taxes, tax basis goodwill and tax law changes. The Company adopted the guidance on January&#160;1, 2021, and determined it did not have a material impact on its results of operations, financial position, cash flows and disclosures.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">ASU 2020-04 - Reference Rate Reform</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> In March 2020, the FASB issued optional guidance to ease the facilitation of the effects of reference rate reform on financial reporting. The guidance applies to certain contract modifications, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. LIBOR is expected to be retired with a full phase-out by the end of 2021 and replaced by new reference rates, which includes SOFR. The guidance can be applied beginning in the interim period that includes March 12, 2020, and cannot be applied to contract modifications or hedging relationships entered into or evaluated after December 31, 2022. The Company has updated its credit agreements to include language regarding the successor or alternate rate to LIBOR, and a review of other contracts and agreements is on-going. The Company does not expect the guidance to have a material impact on its results of operations, financial position, cash flows or disclosures.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Cash and cash equivalents</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Revenue recognition</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 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 30 days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The pipeline 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 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, 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 12 days of receipt of the invoice. For gathering contracts not governed by the tariff, amounts are due within 20 days of invoice receipt. For other contracts not governed by the tariff, payment terms are net 30 days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 an input method based on the cost-to-cost measure of progress on a project. This 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 30 days of receipt. There are no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 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 30 days of receipt. There are no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company recognizes all other revenues when services are rendered or goods are delivered.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Legal costs</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company expenses external legal fees as they are incurred.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Business combinations</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">For all business combinations, the Company preliminarily allocates the purchase price of the acquisitions to the assets acquired and liabilities assumed based on their estimated fair values as of the acquisition dates and are considered provisional until final fair values are determined or the measurement period has passed. The Company expects to record adjustments as it accumulates the information needed to estimate the fair value of assets acquired and liabilities assumed, including working capital balances, estimated fair value of identifiable intangible assets, property, plant and equipment, total consideration and goodwill. The excess of the purchase price over the aggregate fair values is recorded as goodwill. The Company calculated the fair value of the assets acquired in 2020 and 2019 using a market or cost approach (or a combination of both). 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 final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill, and will be made as soon as practical, but no later than 12 months from the respective acquisition dates. Any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Receivables and allowance for expected credit losses</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Receivable consists primarily of trade receivables from the sale of goods and services, which are recorded at the invoiced amount, and contract assets, net of expected credit losses. For more information on contract assets, see Note&#160;3. The Company's trade receivables are all due in 12 months or less.

The Company develops and documents its methodology to determine its allowance for expected credit losses at each of its reportable business segments. Risk characteristics used by the business segments may include customer mix, knowledge of customers and general economic conditions of the various local economies, among others. Specific account balances are written off when management determines the amounts to be uncollectible. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company conducted additional analysis of its receivables and allowance for expected credit losses due to the impacts of COVID-19.

For more information on the Company's operating segments, see Note&#160;17. Goodwill impairment, if any, is measured by comparing the fair value of each reporting unit to its carrying value. If the fair value of a reporting unit exceeds its carrying value, the goodwill of the reporting unit is not impaired. If the carrying value of a reporting unit exceeds its fair value, the Company must record an impairment loss for the amount that the carrying value of the reporting unit, including goodwill, exceeds the fair value of the reporting unit. For the years ended December&#160;31, 2020, 2019 and 2018, there were no impairment losses recorded.

The Company recognizes leases with an original lease term of 12 months or less in income on a straight-line basis over the term of the lease and does not recognize a corresponding right-of-use asset or lease liability. The Company determines the lease term based on the non-cancelable and cancelable periods in each contract. The non-cancelable period consists of the term of the contract that is legally enforceable and cannot be canceled by either party without incurring a significant penalty. The cancelable period is determined by various factors that are based on who has the right to cancel a contract. If only the lessor has the right to cancel the contract, the Company will assume the contract will continue. If the lessee is the only party that has the right to cancel the contract, the Company looks to asset, entity and market-based factors. If both the lessor and the lessee have the right to cancel the contract, the Company assumes the contract will not continue. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The discount rate used to calculate the present value of the lease liabilities is based upon the implied rate within each contract.

When the liability is initially recorded, the Company capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, the Company either settles the obligation for the recorded amount or incurs a gain or loss at its non-regulated operations or incurs a regulatory asset or liability at its regulated operations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Stock-based compensation</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company determines compensation expense for stock-based awards based on the estimated fair values at the grant date and recognizes the related compensation expense over the vesting period.

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.</span></div><div style="margin-top:11pt"><span

The Company expects to recognize the following revenue amounts in future periods related to these remaining performance obligations: $1.6&#160;billion within the next 12&#160;months or less; $298.8&#160;million within the next 13 to 24 months; and $234.3&#160;million in 25 months or more.<span></span>

The Company expects to recover the regulatory assets related to the plants to be retired in future rates. </span></div>If, for any reason, the Company's regulated businesses cease to meet the criteria for application of regulatory accounting for all or part of their operations, the regulatory assets and liabilities relating to those portions ceasing to meet such criteria would be removed from the balance sheet and included in the statement of income or accumulated other comprehensive income (loss) in the period in which the discontinuance of regulatory accounting occurs.<span></span>

These investments, which totaled $100.1&#160;million and $87.0&#160;million at December&#160;31, 2020 and 2019, respectively, are classified as investments on the Consolidated Balance Sheets.

The net unrealized loss on these investments for the year ended December 31, 2018, was $3.6&#160;million.

For the years ended December&#160;31, 2020, 2019 and 2018, dividends declared on common stock were $.8350, $.8150 and $.7950 per common share, respectively. Dividends on common stock are paid quarterly to the stockholders of record less than 30 days prior to the distribution date. For the years ended December&#160;31, 2020, 2019 and 2018, the dividends declared to common stockholders were $167.4&#160;million, $162.1&#160;million and $155.7&#160;million, respectively.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The declaration and payment of dividends of the Company is at the sole discretion of the board of directors.

In addition, certain credit agreements and regulatory limitations of the Company's subsidiaries also contain restrictions on dividend payments. The most restrictive limitation requires the Company's subsidiaries not to permit the ratio of funded debt to capitalization to be greater than 65&#160;percent.

The Company's operations are located within the United States.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The electric segment generates, transmits and distributes electricity in Montana, North Dakota, South Dakota and Wyoming.

These employees were eligible to receive additional defined contribution plan benefits. In October 2018, the Company transferred the liability of certain participants in the defined benefit pension plan, who are currently receiving benefits, to an annuity company. The transfer of the benefit payments for these participants reduced the Company's liability and future premiums. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Effective January&#160;1, 2010, eligibility to receive retiree medical benefits was modified at certain of the Company's businesses.

All other eligible employees must meet the new eligibility criteria of age 60 and 10 years of continuous service at the time they retire to be eligible for a specified company funded Retiree Reimbursement Account. Employees hired after December&#160;31, 2009, will not be eligible for retiree medical benefits at certain of the Company's businesses.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In 2012, the Company modified health care coverage for certain retirees.

<td class="text">Regulatory Matters <div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company regularly reviews the need for electric and natural gas rate changes in each of the jurisdictions in which service is provided. The Company files for rate adjustments to seek recovery of operating costs and capital investments, as well as reasonable returns as allowed by regulators. Certain regulatory proceedings and cases may also contain recurring mechanisms that can have an annual true-up. Examples of these recurring mechanisms include: infrastructure riders, transmission trackers, renewable resource cost adjustment riders, as well as weather normalization and decoupling mechanisms. The following paragraphs summarize the Company's significant regulatory proceedings and cases by jurisdiction, including the status of each open request. The Company is unable to predict the ultimate outcome of these matters, the timing of final decisions of the various regulators and courts, or the effect on the Company's results of operations, financial position or cash flows.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:400;line-height:140%">MNPUC</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">On September&#160;27, 2019, Great Plains filed an application with the MNPUC for a natural gas rate increase of approximately $2.9&#160;million annually or approximately 12.0&#160;percent above current rates. The requested increase was primarily to recover investments in facilities to enhance safety and reliability and the depreciation and taxes associated with the increase in investment.

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)&#160;the matter involves novel or unsettled legal theories.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">At December&#160;31, 2020 and 2019, the Company accrued liabilities which have not been discounted, including liabilities held for sale, of $41.5&#160;million and $29.1&#160;million, respectively. At December&#160;31, 2020 and 2019, the Company also recorded corresponding insurance receivables of $17.5&#160;million and $16.2&#160;million, respectively, and regulatory assets of $21.3&#160;million and $10.5&#160;million, respectively, related to the accrued liabilities. The accruals are for contingencies, including litigation, production taxes, royalty claims and environmental matters. 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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:10.5pt;font-weight:700;line-height:140%">Environmental matters</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">Portland Harbor Site </span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In December 2000, Knife River&#160;- Northwest was named by the EPA as a PRP in connection with the cleanup of the riverbed site adjacent to a commercial property site acquired by Knife River&#160;- Northwest from Georgia-Pacific West, Inc. along the Willamette River. The riverbed site is part of the Portland, Oregon, Harbor Superfund Site where the EPA wants responsible parties to share in the costs of cleanup. 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. Investigative costs are indicated to be in excess of $100&#160;million. The EPA issued an ROD in January 2017 adopting a selected remedy which is expected to take 13 years to complete with a then estimated present value of approximately $1 billion. Corrective action will not be taken until remedial design/remedial action plans are approved by the EPA. Knife River&#160;- Northwest was also notified 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. 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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">At this time, Knife River&#160;- Northwest does not believe it is a responsible party and 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.

The site operated as a former manufactured gas plant from approximately 1907 to 1938 when it was converted to a butane-air plant that operated until 1956. Montana-Dakota or its predecessors owned or controlled the site for a period of the time it operated as a manufactured</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:9pt;font-weight:400;line-height:140%"> </span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">gas plant and Montana-Dakota operated the butane-air plant from 1940 to 1951, at which time it sold the plant. There are no documented wastes or by-products resulting from the mixing or distribution of butane-air gas. Preliminary assessment of a portion of the site provided a recommended remedial alternative for that portion of approximately $560,000. However, the recommended remediation would not address any potential contamination to adjacent parcels that may be impacted by contamination from the manufactured gas plant. An environmental assessment was started in 2020, which is estimated to cost approximately $800,000. Montana-Dakota and another party agreed to voluntarily investigate and remediate the site and that Montana-Dakota will pay two-thirds of the costs for further investigation and remediation of the site. Montana-Dakota has accrued costs of $800,000 for the remediation and investigation costs, and has incurred costs of $130,000 as of December&#160;31, 2020. Montana-Dakota received notice from a prior insurance carrier that it will participate in payment of defense costs incurred in relation to the claim. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">A claim was made against Cascade 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 confirmed that contaminants have affected soil and groundwater at the site, as well as sediments in the adjacent Port Washington Narrows. 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 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 $7.6&#160;million of which $5.0&#160;million has been incurred as of December&#160;31, 2020. Based on the site investigation, preliminary remediation alternative costs were provided by consultants in August 2020; therefore, the accrual for these costs was increased in the third quarter of 2020 by $11.1&#160;million. The preliminary information received through the completion of the data report allowed for the projection of possible costs for a variety of site configurations, remedial measures and potential natural resource damage claims of between $13.6&#160;million and $71.0&#160;million. At December&#160;31, 2020, Cascade has accrued $2.6&#160;million for the remedial investigation and feasibility study, as well as $17.5&#160;million for remediation of this site. The accrual for remediation cost will be reviewed and adjusted, if necessary, after the completion of the feasibility study. In April 2010, Cascade filed a petition with the WUTC for authority to defer the 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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">A claim was made against Cascade 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 $8.0&#160;million to $20.4&#160;million with a selected preferred alternative having an estimated total cost of $9.3&#160;million. The other PRPs will develop a cleanup action plan and, after public review of the cleanup action plan, develop design documents. 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, the plant converted 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.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company has received notices from and entered into agreement with certain of its insurance carriers that they will participate in defense for certain contamination claims subject to full and complete reservations of rights and defenses to insurance coverage.

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><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">At December&#160;31, 2020, 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 $33.7&#160;million.</span></div><span></span>

Prior to the Holding Company Reorganization, the Company included Montana-Dakota and Great Plains, public utility divisions of the Company as of December&#160;31, 2018. On January 2, 2019, the Company announced the completion of the Holding Company Reorganization, which resulted in Montana-Dakota and Great Plains becoming a subsidiary of the Company. Immediately after consummation, the Company had, on a consolidated basis, the same assets, businesses and operations as it had immediately prior to the reorganization. For more information on the reorganization, see Item 8 - Note 1. The prior periods have not been restated and reflect the condensed financial information of Montana-Dakota and Great Plains as of and for the year ended December&#160;31, 2018. Due to the completion of the Holding Company Reorganization, the presentation of the year ended December&#160;31, 2018, will vary from that of and for the years ended December&#160;31, 2020 and 2019. In Schedule I, investments in subsidiaries are presented under the equity method of accounting where the assets and liabilities of the subsidiaries are not consolidated. The investments in net assets of the subsidiaries are recorded on the Condensed Balance Sheets. The income from subsidiaries is reported as equity in earnings of subsidiaries on the Condensed Statements of Income. The material cash inflows on the Condensed Statements of Cash Flows are primarily from the dividends and other payments received from its subsidiaries and the proceeds raised from the issuance of equity securities. The consolidated financial statements of MDU Resources Group, Inc. reflect certain businesses as discontinued operations. These statements should be read in conjunction with the consolidated financial statements and notes thereto of MDU Resources Group, Inc.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:400;line-height:140%">Earnings per common share</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> Please refer to the Consolidated Statements of Income of the registrant for earnings per common share.

Governmental restrictions and guidelines implemented to control the spread of COVID-19 reduced commercial and interpersonal activity throughout the Company's areas of operation. Most of the Company's products and services are considered essential and accordingly operations have been generally allowed to continue. The Company has experienced some inefficiency impacts, including operation suspensions and interruptions at some locations to carry out preventive measures or in response to instances of positive tests or quarantines. The Company has assessed the impacts of the COVID-19 pandemic on its results of operations for the twelve months ended December&#160;31, 2020, and determined there were no material adverse impacts.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In the first quarter of 2020, the Company recorded an out-of-period adjustment to correct the recognition of revenue on a construction contract, which was the result of an overstatement of operating revenue and receivables of $7.7&#160;million and an understatement of operating expense and accounts payable of $1.2&#160;million in the year ended December&#160;31, 2019. This adjustment resulted in an after-tax reduction to net income of $6.7&#160;million in the first quarter of 2020. The Company evaluated the impact of the out-of-period adjustment and concluded it was not material to any previously issued interim and annual consolidated financial statements and the adjustment was not material to the three months ended March&#160;31, 2020, or the twelve months ended December&#160;31, 2020.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">In the fourth quarter of 2020, the Company recorded an out-of-period adjustment to correct the recognition of net periodic benefit cost and other comprehensive income associated with the Company's benefit plans, which was the result of the previous overstatement of benefit plan expenses of $6.5&#160;million, understatement of accumulated other comprehensive loss of $2.7&#160;million and overstatement of regulatory liabilities of $3.8&#160;million from 2006 through 2020. This adjustment resulted in an after-tax increase to net income of $4.4&#160;million in the fourth quarter of 2020. The Company evaluated the impact of the out-of-period adjustment, individually and in the aggregate with the previously mentioned out-of-period adjustment, and concluded it was not material to any previously issued interim and annual consolidated financial statements and the adjustment was not material to the three and twelve months ended December&#160;31, 2020.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Effective January 1, 2020, the Company adopted the requirements of the ASU on the measurement of credit losses on certain financial instruments following a modified retrospective approach, as further discussed in Note 2.

Estimates are used for items such as long-lived assets and goodwill; fair values of acquired assets and liabilities under the acquisition method of accounting; aggregate reserves; property depreciable lives; tax provisions; revenue recognized using the cost-to-cost measure of progress for contracts; expected credit losses; environmental and other loss contingencies; regulatory assets expected to be recovered in rates charged to customers; costs on construction contracts; unbilled revenues; actuarially determined benefit costs; asset retirement obligations; lease classification; present value of right-of-use assets and lease liabilities; and the valuation of stock-based compensation. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised. Consequently, operating results can be affected by revisions to prior accounting estimates.</span></div><span></span>

The guidance introduced a new impairment model known as the current expected credit loss model that replaced the incurred loss impairment methodology previously included under GAAP. This guidance required entities to present certain investments in debt securities, trade accounts receivable and other financial assets at their net carrying value of the amount expected to be collected on the financial statements. The Company adopted the guidance on January&#160;1, 2020, using a modified retrospective approach.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company formed an implementation team to review and assess existing financial assets to identify and evaluate the financial assets subject to the new current expected credit loss model. The Company assessed the impact of the guidance on its processes and internal controls and has identified and updated existing internal controls and processes to ensure compliance with the new guidance; such modifications were deemed insignificant. During the assessment phase, the Company identified the complete portfolio of assets subject to the current expected credit loss model. The Company determined the guidance did not have a material impact on its results of operations, financial position, cash flows or disclosures and did not record a material cumulative effect adjustment upon adoption. See Receivables and allowance for expected credit losses within this note for additional information on the Company's expected credit losses. </span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">ASU 2018-13 - Changes to the Disclosure Requirements for Fair Value Measurement</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> 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 modified, among other things, the disclosures required for Level 3 fair value measurements, including the range and weighted average of significant unobservable inputs. The guidance removed, among other things, the disclosure requirement to disclose transfers between Levels 1 and 2. The Company adopted the guidance on January&#160;1, 2020, and determined it did not have a material impact on its disclosures.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic Bold 2',sans-serif;font-size:9.5pt;font-weight:700;line-height:140%">Recently issued accounting standards not yet adopted</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">ASU 2018-14 - Changes to the Disclosure Requirements for Defined Benefit Plans</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> 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 removed disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and added disclosure requirements identified as relevant. The guidance added, 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 removed, 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 was effective for the Company on January&#160;1, 2021, and must be applied on a retrospective basis. The Company determined the new guidance will not materially impact its consolidated financial statement disclosures.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">ASU 2019-12 - Simplifying the Accounting for Income Taxes</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> In December&#160;2019, the FASB issued guidance on simplifying the accounting for income taxes by removing certain exceptions in ASC 740 and providing simplification amendments. The guidance removed exceptions on intraperiod tax allocations and reporting and provided simplification on accounting for franchise taxes, tax basis goodwill and tax law changes. The Company adopted the guidance on January&#160;1, 2021, and determined it did not have a material impact on its results of operations, financial position, cash flows and disclosures.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-style:italic;font-weight:700;line-height:140%">ASU 2020-04 - Reference Rate Reform</span><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%"> In March 2020, the FASB issued optional guidance to ease the facilitation of the effects of reference rate reform on financial reporting. The guidance applies to certain contract modifications, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. LIBOR is expected to be retired with a full phase-out by the end of 2021 and replaced by new reference rates, which includes SOFR. The guidance can be applied beginning in the interim period that includes March 12, 2020, and cannot be applied to contract modifications or hedging relationships entered into or evaluated after December 31, 2022. The Company has updated its credit agreements to include language regarding the successor or alternate rate to LIBOR, and a review of other contracts and agreements is on-going. The Company does not expect the guidance to have a material impact on its results of operations, financial position, cash flows or disclosures.</span></div><span></span>

<td class="text"><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 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 30 days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The pipeline 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 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, 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 12 days of receipt of the invoice. For gathering contracts not governed by the tariff, amounts are due within 20 days of invoice receipt. For other contracts not governed by the tariff, payment terms are net 30 days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 an input method based on the cost-to-cost measure of progress on a project. This 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 30 days of receipt. There are no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 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 30 days of receipt. There are no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The Company recognizes all other revenues when services are rendered or goods are delivered.</span></div><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">Revenue is recognized when a performance obligation is satisfied by transferring control over a product or service to a customer.

<td class="text">For all business combinations, the Company preliminarily allocates the purchase price of the acquisitions to the assets acquired and liabilities assumed based on their estimated fair values as of the acquisition dates and are considered provisional until final fair values are determined or the measurement period has passed. The Company expects to record adjustments as it accumulates the information needed to estimate the fair value of assets acquired and liabilities assumed, including working capital balances, estimated fair value of identifiable intangible assets, property, plant and equipment, total consideration and goodwill. The excess of the purchase price over the aggregate fair values is recorded as goodwill. The Company calculated the fair value of the assets acquired in 2020 and 2019 using a market or cost approach (or a combination of both). 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 final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill, and will be made as soon as practical, but no later than 12 months from the respective acquisition dates. Any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations.<span></span>

<td class="text"><div><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 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 30 days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">The pipeline 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 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, 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 12 days of receipt of the invoice. For gathering contracts not governed by the tariff, amounts are due within 20 days of invoice receipt. For other contracts not governed by the tariff, payment terms are net 30 days. At this time, the segment has no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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 an input method based on the cost-to-cost measure of progress on a project. This 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 30 days of receipt. There are no material obligations for returns, refunds or other similar obligations.</span></div><div style="margin-top:11pt"><span style="color:#000000;font-family:'Trade Gothic',sans-serif;font-size:8pt;font-weight:400;line-height:140%">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.

<td class="text">The Company is party to claims and lawsuits arising out of its business and that of its consolidated subsidiaries, which may include, but are not limited to, matters involving property damage, personal injury, and environmental, contractual, statutory and regulatory obligations. 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)&#160;the matter involves novel or unsettled legal theories.<span></span>

Such costs are capitalized if they meet both of the following criteria: a.

Based on available evidence, the future revenue will be provided to permit recovery of the previously incurred cost rather than to provide for expected levels of similar future costs. If the revenue will be provided through an automatic rate-adjustment clause, this criterion requires that the regulator's intent clearly be to permit recovery of the previously incurred cost.</p></div>
