We build a mix of 1,200-1,400 square foot stores and new-to-industry ("NTI") 2,800 square foot stores which we believe have low capital expenditure, maintenance and utility requirements relative to our competitors.  We have also developed standardized 208 square feet kiosks with external super coolers when the available land or economics did not support the small store format. Many of our stores require only one or two associates to be present during business hours and 85% of our stores are located on Company-owned property and do not incur any rent expense. The combination of a focused convenience offering and standardized smaller footprint stores allows us to achieve lower overhead costs and on-site costs compared to competitors with a much larger store format. According to the 2019 National Association of Convenience Stores&#8217; State of the Industry Survey, we operate at approximately 29% of the average monthly operating costs for top quartile performing stores in the industry. In addition, we operate among the highest industry safety standards and had a Total Recordable Incident Rate (TRIR) and Days Away from Work (DAW) rate that was substantially lower than the industry averages in 2019 using the most current published data by the Bureau of Labor Statistics.

We compete with other chains of retail fuel stores for fuel supply and in the retail sale of refined products to end consumers, primarily on the basis of price, but also on the basis of convenience and consumer appeal. In addition, we may also face competition from other retail fueling stores that adopt marketing strategies similar to ours by associating with non-traditional retailers, such as quick service restaurants, supermarkets, discount club stores and hypermarkets, particularly in the geographic areas in which we operate. We expect that our industry will continue to trend toward this model, resulting in increased competition to us over time. Moreover, because we do not produce or refine any of the petroleum or other refined products that we market, we compete with retail gasoline companies that have ongoing supply relationships with affiliates or former affiliates that manufacture refined products. We also compete with integrated companies that have their own production and/or refining operations that are at times able to offset losses from marketing operations with profits from producing or refining operations, and may be better positioned to withstand periods of depressed retail margins or supply shortages. In addition, we compete with other retail and wholesale gasoline marketing companies that have more extensive retail outlets and greater brand name recognition. Some of our competitors have been in existence longer than we have and have greater financial, marketing and other resources than we do. As a result, these competitors may have a greater ability to bear the economic risks inherent in all phases of our business and may be able to respond better to changes in the economy and new opportunities within the industry.</span></div><div style="margin-top:9pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The retail gasoline industry in the United States is highly competitive due to ease of entry and constant change in the number and type of retailers offering similar products and services. With respect to merchandise, our retail sites compete with other convenience store chains, independently owned convenience stores, supermarkets, drugstores, discount clubs, gasoline service stations, mass merchants, fast food operations and other similar retail outlets. Non-traditional retailers, including supermarkets, discount club stores and mass merchants, now compete directly with retail gasoline sites. These non-traditional gasoline retailers have obtained a significant share of the gasoline market, and their market share is expected to grow, and these retailers may use promotional pricing or discounts, both at the fuel pump and in the convenience store, to encourage in-store merchandise sales and gasoline sales. In addition, some large retailers and supermarkets are adjusting their store layouts and product prices in an attempt to appeal to convenience store customers. Major competitive factors are: location, ease of access, product and service selection, gasoline brands, pricing, customer service, store appearance, cleanliness and safety.</span></div><div style="margin-top:9pt;text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Market Conditions and Seasonality</span></div><div style="margin-top:5pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Market conditions in the oil and gas industry are cyclical and subject to global economic and political events and new and changing governmental regulations.

In 2019, the EPA and NHTSA jointly finalized part one of the Safer Affordable Fuel-Efficient ("SAFE") Vehicles Rule, which reduced the penalties for violations of CAFE standards and revoked California's authority to set its own fuel economy standards.  In March 2020, EPA and NHTSA finalized part two of the SAFE Vehicles Rule, which amended and made less stringent the 2012 CAFE fuel economy and emissions standards for fleets of 2021-2026 model year cars and light duty trucks.  However, in January 2021, President Biden signed an executive order that, among other things, directed heads of federal agencies to review various rules and regulations promulgated during the previous presidential administration, including parts one and two of the SAFE Vehicles Rule, indicating that a Biden administration may seek to impose stricter fuel economy and emissions standards for cars and light duty trucks and reinstate California's authority to set its own fuel economy standards.  The EPA and NHTSA also regulate GHG emission and fuel efficiency standards for medium and heavy-duty vehicles and in August 2016, jointly finalized "Phase 2" vehicle and engine performance standards covering model years 2021 through 2027, which apply to semi-trucks, large pick-up trucks and vans, and all types and sizes of buses and work trucks.

Oil and domestic wholesale gasoline markets are volatile. General political conditions, acts of war or terrorism, instability in oil producing regions, particularly in the Middle East and South America, and the value of U.S. dollars relative to other foreign currencies, particularly those of oil producing nations, could significantly affect oil supplies and wholesale gasoline costs. In addition, the supply of gasoline and our wholesale purchase costs could be adversely affected in the event of a shortage, which could result from, among other things, lack of capacity at oil refineries, sustained increase in global demand or the fact that our gasoline contracts do not guarantee an uninterrupted, unlimited supply of gasoline. Our wholesale purchase costs could also be adversely affected by increasingly stringent regulations regarding the content and characteristics of fuel products. Significant increases and volatility in wholesale gasoline costs could result in lower gasoline gross margins per gallon. This volatility makes it extremely difficult to predict the effect that future wholesale cost fluctuations will have on our operating results and financial condition in future periods.</span></div><div style="margin-top:5pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Except in limited cases, we typically do not seek to hedge any significant portion of</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">our</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">exposure to the effects of changing prices of commodities. Dramatic increases in oil prices reduce retail gasoline gross margins, because wholesale gasoline costs typically increase faster than retailers are able to pass them along to customers. We purchase refined products, particularly gasoline, needed to supply our retail stores. Therefore, our most significant costs are subject to volatility of prices for these commodities. Our ability to successfully manage operating costs is important because we have little or no influence on the sales prices or regional and worldwide consumer demand for oil and gasoline. Furthermore, oil prices, wholesale motor fuel costs, motor fuel sales volumes, motor fuel gross margins and merchandise sales can be subject to seasonal fluctuations.&#160;For example, consumer demand for motor fuel typically increases during the summer driving season, and typically falls during the winter months.&#160;Travel, recreation and construction are typically higher in these months in the geographic areas in which we operate, increasing the demand for motor fuel and merchandise that we sell. Therefore, our revenues and/or sales volumes are typically higher in the second and third quarters of our fiscal year. A significant change in any of these factors, including a significant decrease in consumer demand (other than typical seasonal variations), could materially affect our motor fuel and merchandise volumes, motor fuel gross profit and overall customer traffic, which in turn could have a material adverse effect on our business, financial condition, results of operations and cash flows.</span></div><div style="margin-top:9pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Further, recessionary economic conditions, higher interest rates, higher gasoline and other energy costs, inflation, increases in commodity prices, higher levels of unemployment, higher consumer debt levels, higher tax rates and other changes in tax laws or other economic factors may affect consumer spending or buying habits, and could adversely affect the demand for products we sell at our retail sites. Unfavorable economic conditions, higher gasoline prices and unemployment levels can affect consumer confidence, spending patterns and vehicle miles driven. These factors can lead to sales declines in both gasoline and general merchandise, and in turn have an adverse impact on our business, financial condition, results of operations and cash flows.</span></div><div style="margin-top:14pt;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Walmart continues to be a key relationship with regard to our Murphy USA network.</span></div><div style="margin-top:5pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">At December&#160;31, 2020, most of our 1,503 Company stores were located in close proximity to</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Walmart</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Supercenter</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">stores.

The RFS program is the regulatory means by which the federal government requires the introduction of an increasing amount of renewable fuel into the fuel supply.  As it is, refiners are obligated to obtain&#8212;either by blending biofuels into petroleum-based fuels or through purchase on the open market--and then retire with the federal government RINs to satisfy their individual obligations.  However, pending litigation and soon-to-begin EPA rulemaking activities concerning the RFS standard could potentially open the door to a change in the point of obligation.  If the point of obligation were to be shifted from refiners to blenders, Murphy USA would potentially have to utilize the RINs that it obtains through its blending activities to satisfy a new obligation and would therefore be unable to sell those RINs to third parties.  This could have an impact on the Company's current business model, unless it were able to pass along these costs to consumers or other parties.</span></div><div style="margin-top:14pt;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">We are exposed to risks associated with the interruption of supply and increased costs as a result of our reliance on third-party supply and transportation of refined products.</span></div><div style="margin-top:5pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We utilize key product supply and wholesale assets, including our pipeline positions and product distribution terminals, to supply our retail fueling stores. Much of our competitive advantage arises out of these proprietary arrangements which, if disrupted, could materially and adversely affect us.

Non-traditional retailers, including supermarkets, discount club stores and mass merchants, now compete directly with retail gasoline sites. These non-traditional gasoline retailers have obtained a significant share of the gasoline market, and their market share is expected to grow, and these retailers may use promotional pricing or discounts, both at the fuel pump and in the convenience store, to encourage in-store merchandise sales and gasoline sales. In addition, some large retailers and supermarkets are adjusting their store layouts and product prices in an attempt to appeal to convenience store customers. Major competitive factors include: location, ease of access, product and service selection, gasoline brands, pricing, customer service, store appearance, cleanliness and safety.

In addition, changes in the types of products and services demanded by consumers may adversely affect our merchandise sales and gross margin. Additionally, negative publicity or perception surrounding gasoline suppliers could adversely affect their reputation and brand image, which may negatively affect our gasoline sales and gross margin.

For more information about our legal matters, see Note 17 &#8220;Contingencies&#8221; to the consolidated historical financial statements for the three years ended December&#160;31, 2020</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">included in this Annual Report on Form 10-K.

These systems are an essential component of our business and growth strategies, and a serious disruption to them could significantly limit our ability to manage and operate our business efficiently. These systems are vulnerable to, among other things, damage and interruption from power loss or natural disasters, computer system and network failures, loss of telecommunications services, physical and electronic loss of data, security breaches and computer viruses, which could result in a loss of sensitive business information, systems interruption or the disruption of our business operations. To protect against unauthorized access or attacks, we have implemented infrastructure protection technologies and disaster recovery plans, but there can be no assurance that a technology systems breach or systems failure, which may occur and go undetected, will not have a material adverse effect on our financial condition or results of operations.  In addition, as of January 2021, Murphy USA completed the required installation of Europay, Mastercard, and Visa ("EMV") chip readers at automated fuel pumps which will protect the Company from being financially responsible for most fraud and counterfeit chargebacks occurring at the point of sale.</span></div><div style="margin-top:14pt;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Our business and our reputation could be adversely affected by the failure to protect sensitive customer, employee or vendor data or to comply with applicable regulations relating to data security and privacy.</span></div><div style="margin-top:5pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In the normal course of our business as a gasoline and merchandise retailer, we obtain large amounts of personal data, including credit and debit card information from our customers. We also engage third-party vendors that provide technology, systems, and services to facilitate our collection, retention, processing and transmission of this information.  While we have invested significant amounts in the protection of our technology systems and maintain what we believe are adequate security controls over individually identifiable customer, employee and vendor data provided to us, a breakdown or a breach in our systems that results in the unauthorized release of individually identifiable customer or other sensitive data could nonetheless occur and have a material adverse effect on our reputation, operating results and financial condition. Such a breakdown or breach could also materially increase the costs we incur to protect against such risks. Also, a material failure on our part, or the part of our vendors, to comply with regulations relating to our obligation to protect such sensitive data or the privacy rights of our customers, employees and others could subject us to fines or other regulatory sanctions and potentially to lawsuits and adversely affect our brand name.</span></div><div style="margin-top:14pt;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">&#160;Compliance with and changes in tax laws could adversely affect our performance.</span></div><div style="margin-top:5pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We are subject to extensive tax liabilities imposed by multiple jurisdictions, including income taxes, indirect taxes (excise/duty, sales/use and gross receipts taxes), payroll taxes, franchise taxes, withholding taxes and ad valorem taxes. Tax laws and regulations are dynamic and subject to change as new laws are passed and new interpretations of existing laws are issued and applied.  This activity could result in increased expenditures for tax liabilities in the future. Many of these liabilities are subject to periodic audits by the respective taxing authority.

These gross margins are commodity-based, change daily and are volatile. While we expect our total fuel sales volumes to grow over time and the gross margins we realize on those sales to remain strong in a normalized environment, these gross margins can change rapidly due to many factors. These factors include, but are not limited to, the price of refined products, interruptions in supply caused by severe weather, travel restrictions and stay-at-home orders imposed during a pandemic such as COVID-19, severe refinery mechanical failures for an extended period of time, and competition in the local markets in which we operate.  The COVID-19 pandemic continues to impact gasoline demand as the work-from-home and virtual school environment is still affecting many areas with no changes expected until mid 2021.  If the recoveries experienced throughout 2020 stall or reverse as a resurgence in COVID-19 infection rates and related government intervention occur, this could cause volume declines. However, incrementally higher fuel margins related to volume decline may help mitigate any adverse financial impact.</span></div><div style="text-indent:90pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:7pt;font-weight:400;line-height:120%">&#160;</span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">29</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div style="text-align:center;text-indent:45pt"><span><br/></span></div></div><div style="text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The cost of our main sales products, gasoline and diesel, is greatly impacted by the cost of crude oil in the United States.&#160;Generally, rising prices for crude oil increase the Company&#8217;s cost for wholesale fuel products purchased.&#160;When wholesale fuel costs rise, the Company is not always able to immediately pass these price increases on to its retail customers at the pump, which in turn squeezes the Company&#8217;s sales margin.&#160;Also, rising prices tend to cause our customers to reduce discretionary fuel consumption, which tends to reduce our fuel sales volumes.&#160;Crude oil prices in 2020 were very volatile during the year ranging from negative territory to a maximum of $63 per barrel due to pandemic related influences and other world events. The lower wholesale prices in 2020 have resulted in a higher fuel contribution on a cents per gallon ("cpg") basis, but this higher contribution was partially offset by declines in the fuel volume sold.  Total fuel contribution (retail fuel margin plus product supply and wholesale ("PS&amp;W") results including Renewable Identification Numbers ("RINs")) was 25.2 cpg in 2020, a 56.3% increase over 2019's total fuel contribution of 16.1 cpg.</span></div><div style="text-indent:90pt"><span style="color:#ff0000;font-family:'Arial',sans-serif;font-size:7pt;font-weight:700;line-height:120%">&#160;</span></div><div style="text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our revenues are impacted by our ability to leverage our diverse supply infrastructure in pursuit of obtaining the lowest cost of fuel supply available; for example, activities such as blending bulk fuel with ethanol and bio-diesel to capture and subsequently sell Renewable Identification Numbers (&#8220;RINs&#8221;).&#160; Under the Energy Policy Act of 2005, the EPA is authorized to set annual quotas establishing the percentage of motor fuels consumed in the United States that must be attributable to renewable fuels. Obligated parties are required to demonstrate that they have met any applicable quotas by submitting a certain amount of RINs to the EPA. RINs in excess of the set quota can then be sold in a market for RINs at then-prevailing prices.&#160; The market price for RINs fluctuates based on a variety of factors, including but not limited to governmental and regulatory action.  There are other market related factors that can impact the net benefit we receive for RINs on a company-wide basis either favorably or unfavorably.&#160; The Renewable Fuel Standard ("RFS") program continues to be unpredictable and ethanol RIN prices ranged from $0.05 to $0.72, with an average sales price of $0.41 per RIN for the year 2020.  Our business model does not depend on our ability to generate revenues from RINs.&#160; Revenue from the sales of RINs is included in &#8220;Other operating revenues&#8221; in the Consolidated Income Statements.</span></div><div style="text-indent:90pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#160;</span></div><div style="text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As of December&#160;31, 2020, we had $800 million of Senior Notes and $212.5 million of term loan outstanding.  We believe that we will generate sufficient cash from operations to fund our ongoing operating requirements.  At December&#160;31, 2020, we had additional available capacity under the committed $325 million credit facilities (subject to the borrowing base), together with capacity under a $150 million incremental uncommitted facility.  We expect to use the credit facilities to provide us with available financing intended to meet any ongoing cash needs in excess of internally generated cash flows. To the extent necessary, we will borrow under these facilities to fund our ongoing operating requirements.There can be no assurances, however, that we will generate sufficient cash from operations or be able to draw on the credit facilities, obtain commitments for our incremental facility and/or obtain and draw upon other credit facilities.

The Company incurred a $14.8 million loss on early debt extinguishment during 2019 related to the 2023 Senior Notes.  Depreciation and amortization expense for 2019 was $3.8 million more than in 2018.</span></div><div style="margin-top:4pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> </span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">36</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div style="text-align:center;text-indent:45pt"><span><br/></span></div></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Non-GAAP Measures</span></div><div style="text-indent:63pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#160;</span></div><div style="text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The following table sets forth the Company&#8217;s EBITDA and Adjusted EBITDA for the three years ended December&#160;31, 2020. &#160;EBITDA means net income (loss) plus net interest expense, plus income tax expense, depreciation and amortization, and Adjusted EBITDA adds back (i)&#160;other non-cash items (e.g., impairment of properties and accretion of asset retirement obligations) and (ii) other items that management does not consider to be meaningful in assessing our operating performance (e.g., (income) from discontinued operations, net settlement proceeds, (gain) loss on sale of assets, loss on early debt extinguishment, transaction costs related to acquisitions, and other non-operating (income) expense).&#160;&#160;EBITDA and Adjusted EBITDA are not measures that are prepared in accordance with U.S. generally accepted accounting principles (GAAP).</span></div><div style="text-indent:90pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#160;</span></div><div style="text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We use Adjusted EBITDA in our operational and financial decision-making, believing that the measure is useful to eliminate certain items in order to focus on what we deem to be an indicator of ongoing operating performance and our ability to generate cash flow from operations. &#160;Adjusted EBITDA is also used by many of our investors, research analysts, investment bankers, and lenders to assess our operating performance.&#160;&#160;We believe that the presentation of Adjusted EBITDA provides useful information to investors because it allows understanding of a key measure that we evaluate internally when making operating and strategic decisions, preparing our annual plan and evaluating our overall performance.

Other sources of operating cash included a $5.9 million benefit in payroll taxes payable which have been deferred under the CARES Act. The changes in accounts receivable and accounts payable were due to timing of invoicing, billing, payments, and receipts.  The variance in prepaid expenses and other current assets and income taxes payable were due to increased pretax income in the current year which moved the Company from a prepaid income tax position to a payable.

Our primary indicator that operating store assets may not be recoverable is consistent negative cash flow over a twenty-four month period for those retail sites that have been open in the same location for a sufficient period to allow for meaningful analysis of ongoing results. We also monitor other factors when evaluating retail sites for impairment, including individual site execution of operating plans and local market conditions.</span></div><div style="margin-top:9pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">When an evaluation is required, the projected future undiscounted cash flows to be generated from each retail site over its remaining economic life are compared to the carrying value of the long-lived assets of that site to determine if a write-down of the carrying value to fair value is required. When determining future cash flows associated with an individual retail site, we make assumptions about key variables such as sales volume, gross margins and expenses. Cash flows vary for each retail site year to year. Changes in market demographics, traffic patterns, competition and other factors impact the overall operations of certain of our individual retail site locations. Similar changes may occur in the future that will require us to record impairment charges. We have not made any material change in the methodology used to estimate future cash flows of retail site locations during the past three years.</span></div><div style="margin-top:9pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our impairment evaluations are based on assumptions we deem to be reasonable. If the actual results of our retail sites are not consistent with the estimates and judgments we have made in estimating future cash flows and determining fair values, our actual impairment losses could vary positively or negatively from our estimated impairment losses.

New tax laws and regulations and changes in existing tax laws and regulations are continuously being enacted or proposed that could result in increased expenditures for tax liabilities that cannot be predicted at this time.

If our actual results of operations differ from such estimates or our estimates of future taxable income change, the valuation allowance may need to be revised. However, an estimate of the sensitivity to earnings that would result from changes in the assumptions and estimates used in determining our tax liabilities is not practicable due to the number of assumptions and tax laws involved, the various potential interpretations of the tax laws, and the wide range of possible outcomes.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company is occasionally challenged by taxing authorities over the amount and/or timing of recognition of revenues and deductions in its various income tax returns.&#160;&#160;Although the Company believes it has adequate accruals for matters not resolved with various taxing authorities, gains or losses could occur in future years from changes in estimates or resolution of outstanding matters.&#160;</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">See Note</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">9</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8220;Income Taxes&#8221; in the accompanying audited</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">consolidated financial statements for the three-year period ended December&#160;31, 2020</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"> </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">for a further discussion of our tax liabilities.</span></div><div style="margin-top:14pt;text-indent:27pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Asset Retirement Obligations</span></div><div style="margin-top:5pt;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We operate above ground and underground storage tanks at our facilities.

We compare our cost estimates with our actual removal cost experience, if any, on an annual basis, and if the actual costs we experience exceed our original estimates, we will recognize an additional liability for estimated future costs to remove the USTs.  Because these estimates are subjective and are currently based on historical costs with adjustments for estimated future changes in the associated costs, the dollar amount of these obligations could change as more information is obtained.

Upon entering into a derivative contract, the Company may designate the derivative as either a fair value hedge or a cash flow hedge, or decide that the contract is not a hedge, and therefore, recognize changes in the fair value of the contract in earnings. The Company documents the relationship between the derivative instrument designated as a hedge and the hedged items as well as its objective for risk management and strategy for use of the hedging instrument to manage the risk.  Derivative instruments designated as fair value or cash flow hedges are linked to specific assets and liabilities or to specific firm commitments or forecasted transactions.  The Company assesses at inception and on an ongoing basis whether a derivative instrument accounted for as a hedge is highly effective in offsetting changes in the fair value or cash flows of the hedged item.  A derivative that is not a highly effective hedge does not qualify for hedge accounting.  The change in the fair value of a qualifying fair value hedge is recorded in earnings along with the gain or loss on the hedged item.  The effective portion of the change in the fair value of a qualifying cash flow hedge is recorded in Accumulated other comprehensive income (AOCI) in the consolidated Balance Sheets until the hedged item is recognized currently in earnings.  If a derivative instrument no longer qualifies as a cash flow hedge and the underlying forecasted transaction is no longer probable of occurring, hedge accounting is discontinued and the gain or loss recorded in Accumulated other comprehensive income is recognized immediately in earnings.</ix:nonNumeric></span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">  </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">See Note 12 "Financial Instruments and Risk Management" and Note 15 "Assets and Liabilities Measured at Fair Value" for further information about the Company&#8217;s derivatives.</span></div><div style="margin-top:9pt"><ix:nonNumeric contextRef="i922892fe8f124b94851f815035e36341_D20200101-20201231" name="us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy" id="id3VybDovL2RvY3MudjEvZG9jOmY0MTM4NTNjN2M1MjQyYjg5ZDYxNmQ5OWFkYjEwY2I2L3NlYzpmNDEzODUzYzdjNTI0MmI4OWQ2MTZkOTlhZGIxMGNiNl8xMjcvZnJhZzpmOTA3MjAzMGU1ZDM0Mzk3YWU3YWEwZjE5NjJjNjY5OC90ZXh0cmVnaW9uOmY5MDcyMDMwZTVkMzQzOTdhZTdhYTBmMTk2MmM2Njk4XzE0MjMw_a59fa940-402c-437a-b6e2-f5394692bf40" continuedAt="ibe8020551de540d39dafffb5b028eed5" escape="true"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">STOCK-BASED COMPENSATION &#8211; The fair value of awarded stock options, restricted stock, restricted stock units and performance stock units is determined based on a combination of management assumptions for awards issued.

The fair value hierarchy is based on the quality of inputs used to measure fair value, with Level 1 being the highest quality and Level 3 being the lowest quality. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1. Level 3 inputs are unobservable inputs which reflect assumptions about pricing by market participants.</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#160;</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">At the balance sheet date, the fair value of commodity derivatives contracts was determined using NYMEX quoted values and the value of the Interest rate swap derivative was derived by using level 3 inputs, but the balances for each were immaterial.  The carrying value of the Company&#8217;s Cash and cash equivalents, Accounts receivable-trade, Trade accounts payable, interest rate swap contracts and accrued liabilities approximates fair value.

The fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties. The table excludes Cash and cash equivalents, Accounts receivable-trade, and Trade accounts payable and accrued liabilities, all of which had fair values approximating carrying amounts. The fair value of Current and Long-term debt was estimated based on rates offered to the Company at that time for debt of the same maturities. The Company has off-balance sheet exposures relating to certain financial guarantees and letters of credit. The fair value of these, which represents fees associated with obtaining the instruments, was nominal.</span></div><div style="text-indent:45pt"><span

In addition, many of these properties have been operated by third parties whose management of hazardous substances was not under the Company&#8217;s control. Under existing laws, the Company could be required to remediate contaminated property (including contaminated groundwater) or to perform remedial actions to prevent future contamination. Certain of these contaminated properties are in various stages of negotiation, investigation, and/or cleanup, and the Company is investigating the extent of any related liability and the availability of applicable defenses. With the sale of the U.S. refineries in 2011, Murphy Oil retained certain liabilities related to environmental matters.

The separation was approved by the Murphy Oil board of directors on August 7, 2013, and was completed on August 30, 2013 through the distribution of 100% of the outstanding capital stock of Murphy USA to holders of Murphy Oil common stock on the record date of August 21, 2013.

Murphy USA also markets gasoline and other products at standalone stores under the Murphy Express brand. At December&#160;31, 2020, Murphy USA had a total of 1,503 Company stores.

Revenue is measured as the amounts of consideration we expect to receive in exchange for transferring goods or providing services.  Excise and sales tax that we collect where we have determined we are the principal in the transaction have been recorded as revenue on a jurisdiction-by-jurisdiction basis.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company enters into buy/sell and similar arrangements when petroleum products are held at one location but are needed at a different location. The Company often pays or receives funds related to the buy/sell arrangement based on location or quality differences. The Company accounts for such transactions on a net basis in its Consolidated Income Statements.  See Note 3 "Revenues" for additional information.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;SHIPPING AND HANDLING COSTS &#x2013; Costs incurred for the shipping and handling of motor fuel are included in Petroleum product cost of goods sold in the Consolidated Income Statements. Costs incurred for the shipping and handling of convenience store merchandise are included in Merchandise cost of goods sold in the Consolidated Income Statements.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;TAXES COLLECTED FROM CUSTOMERS AND REMITTED TO GOVERNMENT AUTHORITIES &#x2013; Excise and other taxes collected on sales of refined products and remitted to governmental agencies are included in operating revenues and operating expenses in the Consolidated Income Statements. Excise taxes on petroleum products collected and remitted were $1.8 billion in 2020, $1.9 billion in 2019, and $1.8 billion in 2018.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;CASH EQUIVALENTS &#x2013; Short-term investments, which include government securities, money market funds and other instruments with government securities as collateral, that have a maturity of three months or less from the date of purchase are classified as cash equivalents.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;ACCOUNTS RECEIVABLE &#x2013; The Company&#x2019;s accounts receivable are recorded at the invoiced amount and do not bear interest. The accounts receivable primarily consists of amounts owed to the Company from credit card companies and by customers for wholesale sales of refined petroleum products. The allowance for doubtful accounts is the Company&#x2019;s best estimate of the amount of probable credit losses on these receivables. The Company reviews this allowance for adequacy at least quarterly and bases its assessment on a combination of current information about its customers and historical write-off experience. Any trade accounts receivable balances &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;written off are charged against the allowance for doubtful accounts. The Company has not experienced any significant credit-related losses in the past three years.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;INVENTORIES &#x2013; Inventories of most finished products are valued at the lower of cost, generally applied on a last-in, first-out (&#x201c;LIFO&#x201d;) basis, or market. Any increments to LIFO inventory volumes are valued based on the first purchase price for these volumes during the year. Merchandise inventories held for resale are carried at average cost. Materials and supplies are valued at the lower of average cost or estimated value. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;VENDOR ALLOWANCES AND REBATES &#x2013; Murphy USA receives payments for vendor allowances, volume rebates and other related payments from various suppliers of its convenience store merchandise. Vendor allowances for price markdowns are credited to merchandise cost of goods sold during the period the related markdown is recognized. Volume rebates of merchandise are recorded as reductions to merchandise cost of goods sold when the merchandise qualifying for the rebate is sold. Slotting and stocking allowances received from a vendor are recorded as a reduction to cost of sales over the period covered by the agreement.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;PROPERTY, PLANT AND EQUIPMENT &#x2013; Additions to property, plant and equipment, including renewals and betterments, are capitalized and recorded at cost. Certain marketing facilities are primarily depreciated using the composite straight-line method with depreciable lives ranging from 16 to 25 years. Gasoline stations, improvements to gasoline stations and other assets are depreciated over 3 to 50 years by individual unit on the straight-line method.  The Company capitalizes interest costs as a component of construction in progress on individually significant projects based on the weighted average interest rates incurred on its long-term borrowings.  Total interest cost capitalized was $1.4 million in 2020 and 2019, respectfully and $2.2 million in 2018.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company has undertaken like-kind exchange ("LKE") transactions under the Federal tax code in an effort to acquire and sell real and personal property in a tax efficient manner. The Company generally enters into forward transactions, in which property is sold and the proceeds are reinvested by acquiring similar property; and reverse transactions, in which property is acquired and similar property is subsequently sold.  A qualified LKE intermediary is used to facilitate these LKE transactions.  Proceeds from forward LKE transactions are held by the intermediary and are classified as restricted cash on the Company's balance sheet because the funds must be reinvested in similar properties.  If the acquisition of suitable LKE properties is not completed within 180 days of the sale of the Company-owned property, the proceeds are distributed to the Company by the intermediary and are reclassified as available cash and applicable income taxes are determined.  An exchange accommodation titleholder, a type of variable interest entity, is used to facilitate reverse like-kind exchanges. The acquired assets are held by the exchange accommodation titleholder until the exchange transactions are complete.  If the Company determines that it is the primary beneficiary of the exchange accommodation titleholder, the replacements assets held by the exchange accommodation titleholder are consolidated and recorded in Property, Plant and Equipment on the Consolidated Balance Sheets.  The unspent proceeds that are held in trust with the intermediary are recorded as noncurrent assets in the Consolidated Balance Sheet as the cash was restricted for the acquisition of property, plant and equipment.   At December&#160;31, 2020 and December&#160;31, 2019, the Company had no open LKE transactions with an intermediary.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;IMPAIRMENT OF ASSETS &#x2013; Long-lived assets, which include property and equipment and finite-lived intangible assets, are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. A long-lived asset is not recoverable if its carrying amount exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. If a long-lived asset is not recoverable, an impairment loss is recognized for the amount by which the carrying amount of the long-lived asset exceeds its fair value, with fair value determined based on discounted estimated net cash flows or other appropriate methods.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;ASSET RETIREMENT OBLIGATIONS &#x2013; The Company records a liability for asset retirement obligations (&#x201c;ARO&#x201d;) equal to the fair value of the estimated cost to retire an asset. The ARO liability is initially recorded in the period in which the obligation meets the definition of a liability, which is generally when the asset is placed in service. The ARO liability is estimated using existing regulatory requirements and anticipated future inflation rates. When the liability is initially recorded, the Company increases the carrying amount of the related long-lived asset by an amount equal to the original liability. The liability is increased over time to reflect the change in its present value, and the capitalized cost is depreciated over the useful life of the related long-lived asset. The Company reevaluates the adequacy of its recorded ARO liability at least annually. Actual costs of asset retirements such as dismantling service stations and site restoration are charged against the related liability. Any difference between costs incurred &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;upon settlement of an asset retirement obligation and the recorded liability is recognized as a gain or loss in the Company&#x2019;s Consolidated Income Statements.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;ENVIRONMENTAL LIABILITIES &#x2013; A liability for environmental matters is established when it is probable that an environmental obligation exists and the cost can be reasonably estimated. If there is a range of reasonably estimated costs, the most likely amount will be recorded, or if no amount is most likely, the minimum of the range is used. Related expenditures are charged against the liability. Environmental remediation liabilities have not been discounted for the time value of future expected payments. Environmental expenditures that have future economic benefit are capitalized.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;INCOME TAXES &#x2013; The Company accounts for income taxes using the asset and liability method. Under this method, income taxes are provided for amounts currently payable and for amounts deferred as tax assets and liabilities based on differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. Deferred income taxes are measured using the enacted tax rates that are assumed will be in effect when the differences reverse. The Company routinely assesses the realizability of deferred tax assets based on available positive and negative evidence including assumptions of future taxable income, tax planning strategies and other pertinent factors.&#160;&#160;A deferred tax asset valuation allowance is recorded when evidence indicates that it is more likely than not that all or a portion of these deferred tax assets will not be realized in a future period.&#160;&#160;The accounting principles for income tax uncertainties permit recognition of income tax benefits only when they are more likely than not to be realized.&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company has elected to classify any interest expense and penalties related to the underpayment of income taxes in Income tax expense in the Consolidated Income Statements.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES &#x2013; The fair value of a derivative instrument is recognized as an asset or liability in the Company&#x2019;s Consolidated Balance Sheets. Upon entering into a derivative contract, the Company may designate the derivative as either a fair value hedge or a cash flow hedge, or decide that the contract is not a hedge, and therefore, recognize changes in the fair value of the contract in earnings. The Company documents the relationship between the derivative instrument designated as a hedge and the hedged items as well as its objective for risk management and strategy for use of the hedging instrument to manage the risk.  Derivative instruments designated as fair value or cash flow hedges are linked to specific assets and liabilities or to specific firm commitments or forecasted transactions.  The Company assesses at inception and on an ongoing basis whether a derivative instrument accounted for as a hedge is highly effective in offsetting changes in the fair value or cash flows of the hedged item.  A derivative that is not a highly effective hedge does not qualify for hedge accounting.  The change in the fair value of a qualifying fair value hedge is recorded in earnings along with the gain or loss on the hedged item.  The effective portion of the change in the fair value of a qualifying cash flow hedge is recorded in Accumulated other comprehensive income (AOCI) in the consolidated Balance Sheets until the hedged item is recognized currently in earnings.  If a derivative instrument no longer qualifies as a cash flow hedge and the underlying forecasted transaction is no longer probable of occurring, hedge accounting is discontinued and the gain or loss recorded in Accumulated other comprehensive income is recognized immediately in earnings.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;  &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;See Note 12 "Financial Instruments and Risk Management" and Note 15 "Assets and Liabilities Measured at Fair Value" for further information about the Company&#x2019;s derivatives.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;STOCK-BASED COMPENSATION &#x2013; The fair value of awarded stock options, restricted stock, restricted stock units and performance stock units is determined based on a combination of management assumptions for awards issued. The Company uses the Black-Scholes option pricing model for computing the fair value of stock options. The primary assumptions made by management included the expected life of the stock option award and the expected volatility of the Company&#x2019;s common stock prices. The Company uses both historical data and current information to support its assumptions. Stock option expense is recognized on a straight-line basis over the requisite service period of&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt; &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;three years. The Company uses a Monte Carlo valuation model to determine the fair value of performance-based stock units that are based on performance compared against a peer group and the related expense is recognized over the&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt; &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;three-year requisite service period. Management estimates the number of all awards that will not vest and adjusts its compensation expense accordingly.  Differences between estimated and actual vested amounts are accounted for as an adjustment to expense when known. See Note 10 "Incentive Plans" or a discussion of the basis of allocation of such costs.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;USE OF ESTIMATES &#x2013; In preparing the financial statements of the Company in conformity with U.S. GAAP, management has made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities. Actual results may differ from the &lt;/span&gt;&lt;/div&gt;estimates. On an ongoing basis, we review our estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.</us-gaap:SignificantAccountingPoliciesTextBlock>

Revenue is measured as the amounts of consideration we expect to receive in exchange for transferring goods or providing services.  Excise and sales tax that we collect where we have determined we are the principal in the transaction have been recorded as revenue on a jurisdiction-by-jurisdiction basis.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company enters into buy/sell and similar arrangements when petroleum products are held at one location but are needed at a different location. The Company often pays or receives funds related to the buy/sell arrangement based on location or quality differences. The Company accounts for such transactions on a net basis in its Consolidated Income Statements.  See Note 3 "Revenues" for additional information.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;SHIPPING AND HANDLING COSTS &#x2013; Costs incurred for the shipping and handling of motor fuel are included in Petroleum product cost of goods sold in the Consolidated Income Statements. Costs incurred for the shipping and handling of convenience store merchandise are included in Merchandise cost of goods sold in the Consolidated Income Statements.&lt;/span&gt;&lt;/div&gt;VENDOR ALLOWANCES AND REBATES &#x2013; Murphy USA receives payments for vendor allowances, volume rebates and other related payments from various suppliers of its convenience store merchandise. Vendor allowances for price markdowns are credited to merchandise cost of goods sold during the period the related markdown is recognized. Volume rebates of merchandise are recorded as reductions to merchandise cost of goods sold when the merchandise qualifying for the rebate is sold. Slotting and stocking allowances received from a vendor are recorded as a reduction to cost of sales over the period covered by the agreement.&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Petroleum product sales (at retail).&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;  For our retail store locations, the revenue related to petroleum product sales is recognized as the fuel is pumped to our customers.  The transaction price at the pump typically includes some portion of sales or excise taxes as levied in the respective jurisdictions.  Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid.  Our customers typically use a mixture of cash, checks, credit cards and debit cards to pay for our products as they are received.  We have accounts receivable from the various credit/debit card providers at any point in time related to product sales made on credit cards and debit cards.

For bulk pipeline sales, we record receivables from customers that are generally collected within a week from custody transfer date.  For our rack product sales, the majority of our customers' accounts are drafted by us within 10 days from product transfer.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Merchandise sales.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;  For our retail store locations, the revenue related to merchandise sales is recognized as the customer completes their purchase at our locations.  The transaction price typically includes some portion of sales tax as levied in the respective jurisdictions.  Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid.  As noted above, a mixture of payment types are used for these revenues and the same terms for credit/debit card receivables are realized.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The most significant judgment with respect to merchandise sales revenue is determining whether we are the principal or agent for some categories of merchandise such as lottery tickets, lotto tickets, newspapers and other small categories of merchandise.  For scratch-off lottery tickets, we have determined we are the principal in the majority of the jurisdictions and therefore we record those sales on a gross basis.  We have some categories of merchandise (such as lotto tickets) where we are the agent and the revenues recorded for those transactions are our net commission only.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In June 2018 the Company initiated a loyalty pilot program through a limited number of its retail locations and was rolled out chain-wide in March 2019.  The customers earn rewards based on their spending or other promotional activities.  This program creates a performance obligation which requires us to defer a portion of sales revenue to the loyalty program participants until they redeem their rewards.  The rewards may be redeemed for free or discounted merchandise or cash discounts on fuel purchases.  Earned rewards expire after an account is inactive for a period of 90 days.  We recognize loyalty revenue when a customer redeems an earned reward.  Deferred revenue associated with Murphy Rewards is included in Trade accounts payable and accrued liabilities in our Consolidated Balance Sheet.  The deferred revenues recorded in 2020 and 2019 were immaterial.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;RINs sales.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;  For the sale of RINs, we recognize revenue when the RIN is transferred to the counter-party and the sale is completed.  Receivables from our counter-parties related to the RIN sales are typically collected within five days of the sale.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Other revenues.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;  Items reported as other operating revenues include collection allowances for excise and sales tax and other miscellaneous items and are recognized as revenue when the transaction is completed.&lt;/span&gt;&lt;/div&gt;</us-gaap:RevenueFromContractWithCustomerPolicyTextBlock>

Certain marketing facilities are primarily depreciated using the composite straight-line method with depreciable lives ranging from 16 to 25 years. Gasoline stations, improvements to gasoline stations and other assets are depreciated over 3 to 50 years by individual unit on the straight-line method.  The Company capitalizes interest costs as a component of construction in progress on individually significant projects based on the weighted average interest rates incurred on its long-term borrowings.  Total interest cost capitalized was $1.4 million in 2020 and 2019, respectfully and $2.2 million in 2018.  The Company has undertaken like-kind exchange ("LKE") transactions under the Federal tax code in an effort to acquire and sell real and personal property in a tax efficient manner. The Company generally enters into forward transactions, in which property is sold and the proceeds are reinvested by acquiring similar property; and reverse transactions, in which property is acquired and similar property is subsequently sold.  A qualified LKE intermediary is used to facilitate these LKE transactions.  Proceeds from forward LKE transactions are held by the intermediary and are classified as restricted cash on the Company's balance sheet because the funds must be reinvested in similar properties.  If the acquisition of suitable LKE properties is not completed within 180 days of the sale of the Company-owned property, the proceeds are distributed to the Company by the intermediary and are reclassified as available cash and applicable income taxes are determined.  An exchange accommodation titleholder, a type of variable interest entity, is used to facilitate reverse like-kind exchanges. The acquired assets are held by the exchange accommodation titleholder until the exchange transactions are complete.  If the Company determines that it is the primary beneficiary of the exchange accommodation titleholder, the replacements assets held by the exchange accommodation titleholder are consolidated and recorded in Property, Plant and Equipment on the Consolidated Balance Sheets.  The unspent proceeds that are held in trust with the intermediary are recorded as noncurrent assets in the Consolidated Balance Sheet as the cash was restricted for the acquisition of property, plant and equipment.</us-gaap:PropertyPlantAndEquipmentPolicyTextBlock>

The ARO liability is estimated using existing regulatory requirements and anticipated future inflation rates. When the liability is initially recorded, the Company increases the carrying amount of the related long-lived asset by an amount equal to the original liability. The liability is increased over time to reflect the change in its present value, and the capitalized cost is depreciated over the useful life of the related long-lived asset. The Company reevaluates the adequacy of its recorded ARO liability at least annually.

Upon entering into a derivative contract, the Company may designate the derivative as either a fair value hedge or a cash flow hedge, or decide that the contract is not a hedge, and therefore, recognize changes in the fair value of the contract in earnings. The Company documents the relationship between the derivative instrument designated as a hedge and the hedged items as well as its objective for risk management and strategy for use of the hedging instrument to manage the risk.  Derivative instruments designated as fair value or cash flow hedges are linked to specific assets and liabilities or to specific firm commitments or forecasted transactions.  The Company assesses at inception and on an ongoing basis whether a derivative instrument accounted for as a hedge is highly effective in offsetting changes in the fair value or cash flows of the hedged item.  A derivative that is not a highly effective hedge does not qualify for hedge accounting.  The change in the fair value of a qualifying fair value hedge is recorded in earnings along with the gain or loss on the hedged item.  The effective portion of the change in the fair value of a qualifying cash flow hedge is recorded in Accumulated other comprehensive income (AOCI) in the consolidated Balance Sheets until the hedged item is recognized currently in earnings.  If a derivative instrument no longer qualifies as a cash flow hedge and the underlying forecasted transaction is no longer probable of occurring, hedge accounting is discontinued and the gain or loss recorded in Accumulated other comprehensive income is recognized immediately in earnings.</us-gaap:DerivativesPolicyTextBlock>

style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;  For our retail store locations, the revenue related to petroleum product sales is recognized as the fuel is pumped to our customers.  The transaction price at the pump typically includes some portion of sales or excise taxes as levied in the respective jurisdictions.  Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid.  Our customers typically use a mixture of cash, checks, credit cards and debit cards to pay for our products as they are received.  We have accounts receivable from the various credit/debit card providers at any point in time related to product sales made on credit cards and debit cards.  These receivables are typically collected in &lt;span style="-sec-ix-hidden:id3VybDovL2RvY3MudjEvZG9jOmY0MTM4NTNjN2M1MjQyYjg5ZDYxNmQ5OWFkYjEwY2I2L3NlYzpmNDEzODUzYzdjNTI0MmI4OWQ2MTZkOTlhZGIxMGNiNl8xMzMvZnJhZzowNDY4YmU0NDc4MmE0MzYzODRjYTcyN2VkM2RiNjg0MS90ZXh0cmVnaW9uOjA0NjhiZTQ0NzgyYTQzNjM4NGNhNzI3ZWQzZGI2ODQxXzIwOTU_10f379a0-ba50-420d-825f-c5b55789842d"&gt;two&lt;/span&gt; to seven days, depending on the terms with the particular credit/debit card providers.  Payment fees retained by the credit/debit card providers are recorded as station and other operating expenses.    &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Petroleum product sales (at wholesale).&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;  Our sales of petroleum products at wholesale are generally recorded as revenue when the deliveries have occurred and legal ownership of the product has transferred to the customer.  &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:6.5pt;font-weight:400;line-height:120%;position:relative;top:-3.5pt;vertical-align:baseline"&gt; &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Title transfer for bulk refined product sales typically occurs at pipeline custody points and upon trucks loading at product terminals.  For bulk pipeline sales, we record receivables from customers that are generally collected within a week from custody transfer date.  For our rack product sales, the majority of our customers' accounts are drafted by us within 10 days from product transfer.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Merchandise sales.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;  For our retail store locations, the revenue related to merchandise sales is recognized as the customer completes their purchase at our locations.  The transaction price typically includes some portion of sales tax as levied in the respective jurisdictions.  Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid.  As noted above, a mixture of payment types are used for these revenues and the same terms for credit/debit card receivables are realized.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The most significant judgment with respect to merchandise sales revenue is determining whether we are the principal or agent for some categories of merchandise such as lottery tickets, lotto tickets, newspapers and other small categories of merchandise.  For scratch-off lottery tickets, we have determined we are the principal in the majority of the jurisdictions and therefore we record those sales on a gross basis.  We have some categories of merchandise (such as lotto tickets) where we are the agent and the revenues recorded for those transactions are our net commission only.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In June 2018 the Company initiated a loyalty pilot program through a limited number of its retail locations and was rolled out chain-wide in March 2019.  The customers earn rewards based on their spending or other promotional activities.  This program creates a performance obligation which requires us to defer a portion of sales revenue to the loyalty program participants until they redeem their rewards.  The rewards may be redeemed for free or discounted merchandise or cash discounts on fuel purchases.  Earned rewards expire after an account is inactive for a period of 90 days.  We recognize loyalty revenue when a customer redeems an earned reward.  Deferred revenue associated with Murphy Rewards is included in Trade accounts payable and accrued liabilities in our Consolidated Balance Sheet.  The deferred revenues recorded in 2020 and 2019 were immaterial.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;RINs sales.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;  For the sale of RINs, we recognize revenue when the RIN is transferred to the counter-party and the sale is completed.  Receivables from our counter-parties related to the RIN sales are typically collected within five days of the sale.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Other revenues.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;  Items reported as other operating revenues include collection allowances for excise and sales tax and other miscellaneous items and are recognized as revenue when the transaction is completed.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;Accounts receivable&lt;/span&gt;&lt;/div&gt;Trade accounts receivable on the balance sheet represents both receivables related to contracts with customers and other trade receivables.  At December&#160;31, 2020 and December&#160;31, 2019, we had $88.3 million and $96.0 million of receivables, respectively, related to contracts with customers recorded.  All of the trade accounts receivable related to contracts with customers outstanding at the end of each period were collected during the succeeding quarter.  These receivables were generally related to credit and debit card transactions along with short term bulk and wholesale sales from our customers, which have a very short settlement window.</us-gaap:RevenueFromContractWithCustomerTextBlock>

The effective date of the agreement was extended to August, 2024.&#160; The credit agreement provides for&#160;a committed $325 million&#160;asset-based loan (ABL)&#160;facility (with availability subject to the borrowing base described below)&#160;and a $200 million&#160;term&#160;loan facility with an additional $50 million available until December 31, 2019.&#160; It&#160;also provides&#160;for a $150 million uncommitted incremental facility. On August 27, 2019, Murphy Oil USA, Inc. borrowed $200 million&#160;under the term loan facility that has a four-year term and prepaid the remaining balance of the prior term loan of $57 million. On December 31, 2019, we borrowed the additional $50 million term loan, and at December&#160;31, 2020 had an outstanding balance of $212.5 million.  The term loan is due August 2023 and requires quarterly principal payments of  $12.5 million beginning April 1, 2020.  As of December 31, 2020, we had zero outstanding under our ABL facility.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The borrowing base is expected, at any time of determination, to be an amount (net of reserves) equal to the sum of:&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:45pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;100% of eligible cash at such time, plus&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;90% of eligible credit card receivables at such time, plus&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;90% of eligible investment grade accounts, plus&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;85% of eligible other accounts, plus&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;80% of eligible product supply/wholesale refined products inventory at such time, plus&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;75% of eligible retail refined products inventory at such time, plus&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:45pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;the lesser of (i) 70% of the average cost of eligible retail merchandise inventory at such time and (ii) 85% of the net orderly liquidation value of eligible retail merchandise inventory at such time.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:45pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The ABL facility includes a $100 million sublimit for the issuance of letters of credit.

If this threshold is met, the tax benefit is then measured and recognized at the largest amount that is greater than 50 percent likely of being realized upon ultimate settlement.

The MUSA 2013 Plan authorizes the Executive Compensation Committee of our Board of Directors (&#x201c;the Committee&#x201d;) to grant non-qualified or incentive stock options, stock appreciation rights, stock awards (including restricted stock and restricted stock unit awards), dividend equivalent units, cash awards, and performance awards to our employees.  No more than 5.5 million shares of common stock may be delivered under the MUSA 2013 Plan and no more than 1 million shares of common stock may be awarded to any one employee, subject to adjustment for changes in capitalization. The maximum cash amount payable pursuant to any &#x201c;performance-based&#x201d; award to any participant in any calendar year is $5.0

February 2014 by the Board of Directors).&#160; At present, the Company expects to issue all shares that vest out of existing treasury shares rather than issuing new common shares.

approximately the next 1.7 years related to unvested share-based compensation arrangements granted by the Company.&#160;&#160;Employees who have stock options are required to net settle their options in shares, after applicable statutory withholding taxes are considered, upon each stock option exercise.  Therefore, no cash is received upon exercise.

restricted stock units (performance units) to certain employees.&#160;&#160;Half of the performance units vest based on a three-year return on average capital employed (ROACE) calculation and the other half vest based on a three-year total shareholder return (TSR) calculation that compares MUSA to a group of 18 peer companies.&#160;&#160;The portion of the awards that vest based on TSR qualify as a market condition and must be valued using a Monte Carlo valuation model.&#160;&#160;For the TSR portion of the awards, the fair value was determined to be $142.07 per unit.&#160;&#160;For the ROACE portion of the awards, the valuation was based on the grant date fair value of $106.72 per unit and the number of awards will be periodically assessed to determine the probability of vesting.&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Changes in performance-based

The use of derivative instruments for risk management is covered by operating policies and is closely monitored by the Company&#x2019;s senior management. The Company does not hold any derivatives for speculative purposes and it does not use derivatives with leveraged or complex features. Derivative instruments are traded primarily with creditworthy major financial institutions or over national exchanges such as the New York Mercantile Exchange (&#x201c;NYMEX&#x201d;).  For accounting purposes, the Company has not designated commodity derivative contracts as hedges, and therefore, it recognizes all gains and losses on these derivative contracts in its Consolidated Statement of Income.  Certain interest rate derivative contracts were accounted for as hedges and &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;gain or loss associated with recording the fair value of these contracts was deferred in AOCI until the anticipated transactions occur.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;  &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;As of December&#160;31, 2020, all current commodity derivative activity is immaterial.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:45pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;At December&#160;31, 2020 and 2019, cash deposits of $0.6 million and $1.0 million, respectively, related to commodity derivative contracts were reported in Prepaid expenses and other current assets in the Consolidated Balance Sheets. These cash deposits have not been used to reduce the reported net liabilities on the derivative contracts at December&#160;31, 2020 and 2019.&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Interest Rate Risks&lt;/span&gt;&lt;/div&gt;Under hedge accounting rules, the Company deferred the net impact associated with the interest rate swap entered into to manage the variability in interest payments for the variable-rate debt in association with $150 million of our outstanding term loan dated August 27, 2019.  The effective date of the hedge was September 27, 2019, and under the swap the Company pays fixed rate interest and receives one month LIBOR to hedge the floating interest rate of the outstanding debt and the balance reduces each quarter by $7.5&#160;million. The balance of term debt remaining applicable to the hedge was $127.5&#160;million at December&#160;31, 2020. During the year December&#160;31, 2020, $0.9 million of realized loss on interest rate swaps was included in interest expense in the Consolidated Statement of Income. The remaining pre-tax loss deferred on these contracts during December&#160;31, 2020, was $3.4 million, which was recorded, net of an income tax benefit of $0.8 million, in other comprehensive income for the year.  During the year ended December 31, 2019, $0.2 million of realized gain on the interest rate swaps was credited to interest expense in the Consolidated Statements of Income. The remaining pre-tax benefit deferred on these contracts at December 31, 2019, was $0.9 million, which is recorded, net of income taxes, of $0.2 million, in AOCI in the Consolidated Balance Sheets.</us-gaap:DerivativeInstrumentsAndHedgingActivitiesDisclosureTextBlock>

The fair value hierarchy is based on the quality of inputs used to measure fair value, with Level 1 being the highest quality and Level 3 being the lowest quality. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1. Level 3 inputs are unobservable inputs which reflect assumptions about pricing by market participants.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;At the balance sheet date, the fair value of commodity derivatives contracts was determined using NYMEX quoted values and the value of the Interest rate swap derivative was derived by using level 3 inputs, but the balances for each were immaterial.  The carrying value of the Company&#x2019;s Cash and cash equivalents, Accounts receivable-trade, Trade accounts payable, interest rate swap contracts and accrued liabilities approximates fair value.  See also Note 12 "Financial Instruments and Risk Management in these consolidated financial statements for the period ended December 31, 2020, for more information.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The following table presents the carrying amounts and estimated fair values of financial instruments held by the Company at December&#160;31, 2020 and 2019.

Examples of such governmental action include, but are by no means limited to: tax increases and retroactive tax claims; import and export controls; price controls; allocation of supplies of crude oil and petroleum products and other goods; laws and regulations intended for the promotion of safety and the protection and/or remediation of the environment; governmental support for other forms of energy; and laws and regulations affecting the Company&#x2019;s relationships with employees, suppliers, customers, stockholders and others. Because governmental actions are often motivated by political considerations, may be taken without full consideration of their consequences, and may &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;be taken in response to actions of other governments, it is not practical to attempt to predict the likelihood of such actions, the form the actions may take or the effect such actions may have on the Company.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;ENVIRONMENTAL MATTERS AND LEGAL MATTERS &#x2014; Murphy USA is subject to numerous federal, state and local laws and regulations dealing with the environment. Violation of such environmental laws, regulations and permits can result in the imposition of significant civil and criminal penalties, injunctions and other sanctions. A discharge of hazardous substances into the environment could, to the extent such event is not insured, subject the &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Company to substantial expense, including both the cost to comply with applicable regulations and claims by neighboring landowners and other third parties for any personal injury, property damage and other losses that might result.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company currently owns or leases, and has in the past owned or leased, properties at which hazardous substances have been or are being handled. Although the Company believes it has used operating and disposal practices that were standard in the industry at the time, hazardous substances may have been disposed of or released on or under the properties owned or leased by the Company or on or under other locations where they have been taken for disposal. In addition, many of these properties have been operated by third parties whose management of hazardous substances was not under the Company&#x2019;s control. Under existing laws, the Company could be required to remediate contaminated property (including contaminated groundwater) or to perform remedial actions to prevent future contamination. Certain of these contaminated properties are in various stages of negotiation, investigation, and/or cleanup, and the Company is investigating the extent of any related liability and the availability of applicable defenses. With the sale of the U.S. refineries in 2011, Murphy Oil retained certain liabilities related to environmental matters. Murphy Oil also obtained insurance covering certain levels of environmental exposures. With respect to the previously owned refinery properties, Murphy Oil retained those liabilities in the Separation and Distribution agreement that was entered into related to the separation on August 30, 2013.&#160;&#160;With respect to any remaining potential liabilities, the Company believes costs related to these sites will not have a material adverse effect on Murphy USA&#x2019;s net income, financial position or liquidity in a future period.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:45pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Certain environmental expenditures are likely to be recovered by the Company from other sources, primarily environmental funds maintained by certain states. Since no assurance can be given that future recoveries from other sources will occur, the Company has not recorded a benefit for likely recoveries at December&#160;31, 2020, however certain jurisdictions provide reimbursement for these expenses which have been considered in recording the net exposure. The U.S. Environmental Protection Agency (EPA) currently considers the Company a Potentially Responsible Party (PRP) at one Superfund site.&#160;&#160;As to the site, the potential total cost to all parties to perform necessary remedial work at this site may be substantial. However, based on current negotiations and available information, the Company believes that it is a de minimis party as to ultimate responsibility at the Superfund site. Accordingly, the Company has not recorded a liability for remedial costs at the Superfund site at December&#160;31, 2020. The Company could be required to bear a pro rata share of costs attributable to nonparticipating PRPs or could be assigned additional responsibility for remediation at this site or other Superfund sites. The Company believes that its share of the ultimate costs to clean-up this site will be immaterial and will not have a material adverse effect on its net income, financial position or liquidity in a future period.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Based on information currently available to the Company, the amount of future remediation costs to be incurred to address known contamination sites is not expected to have a material adverse effect on the Company&#x2019;s future net income, cash flows or liquidity. However, there is the possibility that additional environmental expenditures could be required to address contamination, including as a result of discovering additional contamination or the imposition of new or revised requirements applicable to known contamination.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Murphy USA is engaged in a number of other legal proceedings, all of which the Company considers routine and incidental to its business. Based on information currently available to the Company, the ultimate resolution of those other legal matters is not expected to have a material adverse effect on the Company&#x2019;s net income, financial condition or liquidity in a future period.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;INSURANCE &#x2014; The Company maintains insurance coverage at levels that are customary and consistent with industry standards for companies of similar size. Murphy USA maintains statutory workers compensation insurance with a deductible of $1.0 million per occurrence, general liability insurance with a deductible of $3.0 million per occurrence, and auto liability insurance with a deductible of $0.3 million per occurrence.  As of December&#160;31, 2020, there were a number of outstanding claims that are of a routine nature. The estimated incurred but unpaid liabilities relating to these claims are included in Trade account payables and accrued liabilities on the Consolidated Balance Sheets. While the ultimate outcome of these claims cannot presently be determined, management believes that the &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;accrued liability of $27.8 million will be sufficient to cover the related liability and that the ultimate disposition of these claims will have no material effect on the Company&#x2019;s financial position and results of operations.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company has obtained insurance coverage as appropriate for the business in which it is engaged, but may incur losses that are not covered by insurance or reserves, in whole or in part, and such losses could adversely affect our results of operations and financial position.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;TAX MATTERS &#x2014; Murphy USA is subject to extensive tax liabilities imposed by multiple jurisdictions, including income taxes, indirect taxes (excise/duty, sales/use and gross receipts taxes), payroll taxes, franchise taxes, withholding taxes and ad valorem taxes. New tax laws and regulations and changes in existing tax laws and regulations are continuously being enacted or proposed that could result in increased expenditures for tax liabilities in the future. Many of these liabilities are subject to periodic audits by the respective taxing authority. Subsequent changes to our tax liabilities because of these audits may subject us to interest and penalties.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;OTHER MATTERS &#x2014; In the normal course of its business, the Company is required under certain contracts with various governmental authorities and others to provide financial guarantees or letters of credit that may be drawn upon if the Company fails to perform under those contracts. At December&#160;31, 2020, the Company had contingent liabilities of $13.0 million on outstanding letters of credit. The Company has not accrued a liability in its balance sheet related to these financial guarantees and letters of credit because it is believed that the likelihood of having these drawn is remote.&lt;/span&gt;&lt;/div&gt;</us-gaap:LossContingencyDisclosures>

Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. The Company's leases have remaining lease terms of approximately 1 year to 20 years, which may include the option to extend the lease when it is reasonably certain the Company will exercise the option.  Most leases include one or more options to renew, with renewal terms that can extend the lease term from 5 to 20 years or more.  The exercise of lease renewal options is at the Company's sole discretion.  Due to the uncertainties of future markets, economic factors, technology changes, demographic shifts and behavior, environmental regulatory requirements and other information that impacts decisions as to station location, management has determined that it was not reasonably certain to exercise contract options and they are not included in the lease term.  Additionally, short-term leases and leases with variable lease costs are immaterial.  The Company reviews all options to extend, terminate, or otherwise modify its lease agreements to determine if changes are required to the right of use assets and liabilities.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;As the implicit interest rate is not readily determinable in most of the Company's lease agreements, the Company uses its estimated secured incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:6pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Lessor &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2014; We have various arrangements for certain spaces for food service and vending equipment under which we are the lessor.  These leases meet the criteria for operating lease classification.  Lease income associated with these leases is immaterial.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Lessee &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2014;We lease land for 232 stations, one terminal, and various equipment.  Our lease agreements do not contain any material residual value guarantees and approximately 102 sites leased from Walmart contain restrictive covenants, though the restrictions are deemed to have an immaterial impact.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span

Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. The Company's leases have remaining lease terms of approximately 1 year to 20 years, which may include the option to extend the lease when it is reasonably certain the Company will exercise the option.  Most leases include one or more options to renew, with renewal terms that can extend the lease term from 5 to 20 years or more.  The exercise of lease renewal options is at the Company's sole discretion.  Due to the uncertainties of future markets, economic factors, technology changes, demographic shifts and behavior, environmental regulatory requirements and other information that impacts decisions as to station location, management has determined that it was not reasonably certain to exercise contract options and they are not included in the lease term.  Additionally, short-term leases and leases with variable lease costs are immaterial.  The Company reviews all options to extend, terminate, or otherwise modify its lease agreements to determine if changes are required to the right of use assets and liabilities.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;As the implicit interest rate is not readily determinable in most of the Company's lease agreements, the Company uses its estimated secured incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:6pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Lessor &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2014; We have various arrangements for certain spaces for food service and vending equipment under which we are the lessor.  These leases meet the criteria for operating lease classification.  Lease income associated with these leases is immaterial.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Lessee &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2014;We lease land for 232 stations, one terminal, and various equipment.  Our lease agreements do not contain any material residual value guarantees and approximately 102 sites leased from Walmart contain restrictive covenants, though the restrictions are deemed to have an immaterial impact.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span

Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. The Company's leases have remaining lease terms of approximately 1 year to 20 years, which may include the option to extend the lease when it is reasonably certain the Company will exercise the option.  Most leases include one or more options to renew, with renewal terms that can extend the lease term from 5 to 20 years or more.  The exercise of lease renewal options is at the Company's sole discretion.  Due to the uncertainties of future markets, economic factors, technology changes, demographic shifts and behavior, environmental regulatory requirements and other information that impacts decisions as to station location, management has determined that it was not reasonably certain to exercise contract options and they are not included in the lease term.  Additionally, short-term leases and leases with variable lease costs are immaterial.  The Company reviews all options to extend, terminate, or otherwise modify its lease agreements to determine if changes are required to the right of use assets and liabilities.As the implicit interest rate is not readily determinable in most of the Company's lease agreements, the Company uses its estimated secured incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.</us-gaap:LesseeLeasesPolicyTextBlock>

ASU 2016-13 was subsequently modified by ASU 2018-19,  ASU 2019-04, ASU 2019-05, and ASU 2019-11.  This ASU changed the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life, which will result in timelier recognition of losses.  ASU 2016-13 and the associated modifications was effective for the Company on January 1, 2020 and required a modified retrospective approach with an adjustment at the beginning of year for any adjustment due to its adoption.  In applying ASC 326 at January 1, 2020, the Company calculated an adjustment to its estimated credit loss allowance and lowered the allowance by $1.1 million, which was credited to retained earnings under the modified retrospective approach.  The adjustment reflects the Company's changes in credit practices since its spin-of in 2013 which includes tighter applied credit terms and faster turnover of receivables resulting in a decrease to its estimated credit loss allowance as of January 1, 2020.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract".  This ASU aligns the accounting treatment for capitalizing implementation costs incurred by customers in cloud computing arrangements in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software.  This guidance was effective for the Company on January 1, 2020.  The amendments in this update were applied prospectively to all implementation costs incurred after the date of adoption.  The Company assessed the effect that this ASU had on our financial position, results of operations, and disclosures and determined that this update did not have a material impact on the Company's consolidated financial statements.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In August 2018, the FASB issued ASU 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement".  This ASU eliminated, amended, and  added disclosure requirements for fair value measurements in Topic 820, including disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for level 3 measurements.

ASU 2016-13 was subsequently modified by ASU 2018-19,  ASU 2019-04, ASU 2019-05, and ASU 2019-11.  This ASU changed the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life, which will result in timelier recognition of losses.  ASU 2016-13 and the associated modifications was effective for the Company on January 1, 2020 and required a modified retrospective approach with an adjustment at the beginning of year for any adjustment due to its adoption.  In applying ASC 326 at January 1, 2020, the Company calculated an adjustment to its estimated credit loss allowance and lowered the allowance by $1.1 million, which was credited to retained earnings under the modified retrospective approach.  The adjustment reflects the Company's changes in credit practices since its spin-of in 2013 which includes tighter applied credit terms and faster turnover of receivables resulting in a decrease to its estimated credit loss allowance as of January 1, 2020.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract".  This ASU aligns the accounting treatment for capitalizing implementation costs incurred by customers in cloud computing arrangements in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software.  This guidance was effective for the Company on January 1, 2020.  The amendments in this update were applied prospectively to all implementation costs incurred after the date of adoption.

This ASU eliminated, amended, and  added disclosure requirements for fair value measurements in Topic 820, including disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for level 3 measurements.  This guidance was effective for the Company on January 1, 2020.  The Company assessed the effect that this ASU had on our financial position, results of operations, and disclosures and determined that this update did not have a material impact on the Company's consolidated financial statements.

Due to the close proximity of the completion of the acquisition to the filing of this Form 10-K, the Company is unable to provide a preliminary purchase price allocation of the fair value of assets acquired and liabilities assumed in the transaction.  The Company will disclose a preliminary purchase price allocation in its Form 10-Q for the period ending March 31, 2021.  The financial results for QuickChek will be included in the Company's consolidated financial statements from the date of acquisition.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Also, on January 29, 2021, the Company refinanced its existing credit facility and issued new senior unsecured notes.  The Company entered into a new credit agreement that provides for a secured term loan of $400&#160;million (which was borrowed in full) and revolving credit commitments of $350&#160;million.  The term loan expires seven years from the date of issuance and the revolving credit facility matures in five years.  The secured term loan accrues interest at LIBOR plus 1.75%, subject to a LIBOR floor of 0.50% and the revolving credit facility accrues interest, when drawn, at LIBOR plus a range of 1.75% to 2.25% depending on a total debt to EBITDA ratio covenant.  As part of entering into the new credit agreement, the prior agreement which consisted of an ABL facility and term loan was fully repaid and retired.  &lt;/span&gt;&lt;/div&gt;The senior unsecured notes were issued in an aggregate principal of $500&#160;million and bear interest at a rate of  3.750% per annum.  The notes mature on February 15, 2031, and interest is payable every February 15 and August beginning August 15, 2021.  These senior unsecured notes contain covenants that are essentially identical to the Company's other outstanding senior notes.</us-gaap:SubsequentEventsTextBlock>

Vendor allowances for price markdowns are credited to merchandise cost of goods sold during the period the related markdown is recognized.

Gasoline stations, improvements to gasoline stations and other assets are depreciated over 3 to 50 years by individual unit on the straight-line method.  The Company capitalizes interest costs as a component of construction in progress on individually significant projects based on the weighted average interest rates incurred on its long-term borrowings.  Total interest cost capitalized was $1.4 million in 2020 and 2019, respectfully and $2.2 million in 2018.  </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company has undertaken like-kind exchange ("LKE") transactions under the Federal tax code in an effort to acquire and sell real and personal property in a tax efficient manner. The Company generally enters into forward transactions, in which property is sold and the proceeds are reinvested by acquiring similar property; and reverse transactions, in which property is acquired and similar property is subsequently sold.  A qualified LKE intermediary is used to facilitate these LKE transactions.  Proceeds from forward LKE transactions are held by the intermediary and are classified as restricted cash on the Company's balance sheet because the funds must be reinvested in similar properties.  If the acquisition of suitable LKE properties is not completed within 180 days of the sale of the Company-owned property, the proceeds are distributed to the Company by the intermediary and are reclassified as available cash and applicable income taxes are determined.  An exchange accommodation titleholder, a type of variable interest entity, is used to facilitate reverse like-kind exchanges. The acquired assets are held by the exchange accommodation titleholder until the exchange transactions are complete.  If the Company determines that it is the primary beneficiary of the exchange accommodation titleholder, the replacements assets held by the exchange accommodation titleholder are consolidated and recorded in Property, Plant and Equipment on the Consolidated Balance Sheets.  The unspent proceeds that are held in trust with the intermediary are recorded as noncurrent assets in the Consolidated Balance Sheet as the cash was restricted for the acquisition of property, plant and equipment.   At December&#160;31, 2020 and December&#160;31, 2019, the Company had no open LKE transactions with an intermediary.</span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">IMPAIRMENT OF ASSETS &#8211; Long-lived assets, which include property and equipment and finite-lived intangible assets, are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. A long-lived asset is not recoverable if its carrying amount exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. If a long-lived asset is not recoverable, an impairment loss is recognized for the amount by which the carrying amount of the long-lived asset exceeds its fair value, with fair value determined based on discounted estimated net cash flows or other appropriate methods.</span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">ASSET RETIREMENT OBLIGATIONS &#8211; The Company records a liability for asset retirement obligations (&#8220;ARO&#8221;) equal to the fair value of the estimated cost to retire an asset. The ARO liability is initially recorded in the period in which the obligation meets the definition of a liability, which is generally when the asset is placed in service. The ARO liability is estimated using existing regulatory requirements and anticipated future inflation rates. When the liability is initially recorded, the Company increases the carrying amount of the related long-lived asset by an amount equal to the original liability. The liability is increased over time to reflect the change in its present value, and the capitalized cost is depreciated over the useful life of the related long-lived asset. The Company reevaluates the adequacy of its recorded ARO liability at least annually. Actual costs of asset retirements such as dismantling service stations and site restoration are charged against the related liability.

If there is a range of reasonably estimated costs, the most likely amount will be recorded, or if no amount is most likely, the minimum of the range is used. Related expenditures are charged against the liability. Environmental remediation liabilities have not been discounted for the time value of future expected payments. Environmental expenditures that have future economic benefit are capitalized.</span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">INCOME TAXES &#8211; The Company accounts for income taxes using the asset and liability method. Under this method, income taxes are provided for amounts currently payable and for amounts deferred as tax assets and liabilities based on differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. Deferred income taxes are measured using the enacted tax rates that are assumed will be in effect when the differences reverse. The Company routinely assesses the realizability of deferred tax assets based on available positive and negative evidence including assumptions of future taxable income, tax planning strategies and other pertinent factors.&#160;&#160;A deferred tax asset valuation allowance is recorded when evidence indicates that it is more likely than not that all or a portion of these deferred tax assets will not be realized in a future period.&#160;&#160;The accounting principles for income tax uncertainties permit recognition of income tax benefits only when they are more likely than not to be realized.&#160;&#160;</span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company has elected to classify any interest expense and penalties related to the underpayment of income taxes in Income tax expense in the Consolidated Income Statements.</span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES &#8211; The fair value of a derivative instrument is recognized as an asset or liability in the Company&#8217;s Consolidated Balance Sheets. Upon entering into a derivative contract, the Company may designate the derivative as either a fair value hedge or a cash flow hedge, or decide that the contract is not a hedge, and therefore, recognize changes in the fair value of the contract in earnings. The Company documents the relationship between the derivative instrument designated as a hedge and the hedged items as well as its objective for risk management and strategy for use of the hedging instrument to manage the risk.  Derivative instruments designated as fair value or cash flow hedges are linked to specific assets and liabilities or to specific firm commitments or forecasted transactions.  The Company assesses at inception and on an ongoing basis whether a derivative instrument accounted for as a hedge is highly effective in offsetting changes in the fair value or cash flows of the hedged item.  A derivative that is not a highly effective hedge does not qualify for hedge accounting.  The change in the fair value of a qualifying fair value hedge is recorded in earnings along with the gain or loss on the hedged item.  The effective portion of the change in the fair value of a qualifying cash flow hedge is recorded in Accumulated other comprehensive income (AOCI) in the consolidated Balance Sheets until the hedged item is recognized currently in earnings.  If a derivative instrument no longer qualifies as a cash flow hedge and the underlying forecasted transaction is no longer probable of occurring, hedge accounting is discontinued and the gain or loss recorded in Accumulated other comprehensive income is recognized immediately in earnings.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">  </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">See Note 12 "Financial Instruments and Risk Management" and Note 15 "Assets and Liabilities Measured at Fair Value" for further information about the Company&#8217;s derivatives.</span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">STOCK-BASED COMPENSATION &#8211; The fair value of awarded stock options, restricted stock, restricted stock units and performance stock units is determined based on a combination of management assumptions for awards issued.

The primary assumptions made by management included the expected life of the stock option award and the expected volatility of the Company&#8217;s common stock prices.

The customers earn rewards based on their spending or other promotional activities.  This program creates a performance obligation which requires us to defer a portion of sales revenue to the loyalty program participants until they redeem their rewards.  The rewards may be redeemed for free or discounted merchandise or cash discounts on fuel purchases.  Earned rewards expire after an account is inactive for a period of 90 days.  We recognize loyalty revenue when a customer redeems an earned reward.  Deferred revenue associated with Murphy Rewards is included in Trade accounts payable and accrued liabilities in our Consolidated Balance Sheet.  The deferred revenues recorded in 2020 and 2019 were immaterial.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">RINs sales.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">  For the sale of RINs, we recognize revenue when the RIN is transferred to the counter-party and the sale is completed.

All of the trade accounts receivable related to contracts with customers outstanding at the end of each period were collected during the succeeding quarter.  These receivables were generally related to credit and debit card transactions along with short term bulk and wholesale sales from our customers, which have a very short settlement window.<span></span>

The fair value hierarchy is based on the quality of inputs used to measure fair value, with Level 1 being the highest quality and Level 3 being the lowest quality. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1. Level 3 inputs are unobservable inputs which reflect assumptions about pricing by market participants.</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#160;</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">At the balance sheet date, the fair value of commodity derivatives contracts was determined using NYMEX quoted values and the value of the Interest rate swap derivative was derived by using level 3 inputs, but the balances for each were immaterial.  The carrying value of the Company&#8217;s Cash and cash equivalents, Accounts receivable-trade, Trade accounts payable, interest rate swap contracts and accrued liabilities approximates fair value.

The fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties. The table excludes Cash and cash equivalents, Accounts receivable-trade, and Trade accounts payable and accrued liabilities, all of which had fair values approximating carrying amounts. The fair value of Current and Long-term debt was estimated based on rates offered to the Company at that time for debt of the same maturities. The Company has off-balance sheet exposures relating to certain financial guarantees and letters of credit. The fair value of these, which represents fees associated with obtaining the instruments, was nominal.</span></div><div style="text-indent:45pt"><span

Although the Company believes it has used operating and disposal practices that were standard in the industry at the time, hazardous substances may have been disposed of or released on or under the properties owned or leased by the Company or on or under other locations where they have been taken for disposal. In addition, many of these properties have been operated by third parties whose management of hazardous substances was not under the Company&#8217;s control. Under existing laws, the Company could be required to remediate contaminated property (including contaminated groundwater) or to perform remedial actions to prevent future contamination. Certain of these contaminated properties are in various stages of negotiation, investigation, and/or cleanup, and the Company is investigating the extent of any related liability and the availability of applicable defenses. With the sale of the U.S. refineries in 2011, Murphy Oil retained certain liabilities related to environmental matters. Murphy Oil also obtained insurance covering certain levels of environmental exposures. With respect to the previously owned refinery properties, Murphy Oil retained those liabilities in the Separation and Distribution agreement that was entered into related to the separation on August 30, 2013.&#160;&#160;With respect to any remaining potential liabilities, the Company believes costs related to these sites will not have a material adverse effect on Murphy USA&#8217;s net income, financial position or liquidity in a future period.</span></div><div style="text-indent:45pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">&#160;</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Certain environmental expenditures are likely to be recovered by the Company from other sources, primarily environmental funds maintained by certain states. Since no assurance can be given that future recoveries from other sources will occur, the Company has not recorded a benefit for likely recoveries at December&#160;31, 2020, however certain jurisdictions provide reimbursement for these expenses which have been considered in recording the net exposure. The U.S. Environmental Protection Agency (EPA) currently considers the Company a Potentially Responsible Party (PRP) at one Superfund site.&#160;&#160;As to the site, the potential total cost to all parties to perform necessary remedial work at this site may be substantial. However, based on current negotiations and available information, the Company believes that it is a de minimis party as to ultimate responsibility at the Superfund site. Accordingly, the Company has not recorded a liability for remedial costs at the Superfund site at December&#160;31, 2020. The Company could be required to bear a pro rata share of costs attributable to nonparticipating PRPs or could be assigned additional responsibility for remediation at this site or other Superfund sites. The Company believes that its share of the ultimate costs to clean-up this site will be immaterial and will not have a material adverse effect on its net income, financial position or liquidity in a future period.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Based on information currently available to the Company, the amount of future remediation costs to be incurred to address known contamination sites is not expected to have a material adverse effect on the Company&#8217;s future net income, cash flows or liquidity. However, there is the possibility that additional environmental expenditures could be required to address contamination, including as a result of discovering additional contamination or the imposition of new or revised requirements applicable to known contamination.</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">&#160;&#160;</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Murphy USA is engaged in a number of other legal proceedings, all of which the Company considers routine and incidental to its business.

Murphy USA maintains statutory workers compensation insurance with a deductible of $1.0 million per occurrence, general liability insurance with a deductible of $3.0 million per occurrence, and auto liability insurance with a deductible of $0.3 million per occurrence.  As of December&#160;31, 2020, there were a number of outstanding claims that are of a routine nature. The estimated incurred but unpaid liabilities relating to these claims are included in Trade account payables and accrued liabilities on the Consolidated Balance Sheets. While the ultimate outcome of these claims cannot presently be determined, management believes that the </span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">accrued liability of $27.8 million will be sufficient to cover the related liability and that the ultimate disposition of these claims will have no material effect on the Company&#8217;s financial position and results of operations.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company has obtained insurance coverage as appropriate for the business in which it is engaged, but may incur losses that are not covered by insurance or reserves, in whole or in part, and such losses could adversely affect our results of operations and financial position.</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">&#160;</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">TAX MATTERS &#8212; Murphy USA is subject to extensive tax liabilities imposed by multiple jurisdictions, including income taxes, indirect taxes (excise/duty, sales/use and gross receipts taxes), payroll taxes, franchise taxes, withholding taxes and ad valorem taxes. New tax laws and regulations and changes in existing tax laws and regulations are continuously being enacted or proposed that could result in increased expenditures for tax liabilities in the future. Many of these liabilities are subject to periodic audits by the respective taxing authority.

At December&#160;31, 2020, the Company had contingent liabilities of $13.0 million on outstanding letters of credit. The Company has not accrued a liability in its balance sheet related to these financial guarantees and letters of credit because it is believed that the likelihood of having these drawn is remote.</span></div><span></span>

Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. The Company's leases have remaining lease terms of approximately 1 year to 20 years, which may include the option to extend the lease when it is reasonably certain the Company will exercise the option.  Most leases include one or more options to renew, with renewal terms that can extend the lease term from 5 to 20 years or more.  The exercise of lease renewal options is at the Company's sole discretion.  Due to the uncertainties of future markets, economic factors, technology changes, demographic shifts and behavior, environmental regulatory requirements and other information that impacts decisions as to station location, management has determined that it was not reasonably certain to exercise contract options and they are not included in the lease term.  Additionally, short-term leases and leases with variable lease costs are immaterial.  The Company reviews all options to extend, terminate, or otherwise modify its lease agreements to determine if changes are required to the right of use assets and liabilities.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As the implicit interest rate is not readily determinable in most of the Company's lease agreements, the Company uses its estimated secured incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.  </span></div><div><span><br/></span></div><div style="margin-bottom:6pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Lessor </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8212; We have various arrangements for certain spaces for food service and vending equipment under which we are the lessor.

Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. The Company's leases have remaining lease terms of approximately 1 year to 20 years, which may include the option to extend the lease when it is reasonably certain the Company will exercise the option.  Most leases include one or more options to renew, with renewal terms that can extend the lease term from 5 to 20 years or more.  The exercise of lease renewal options is at the Company's sole discretion.  Due to the uncertainties of future markets, economic factors, technology changes, demographic shifts and behavior, environmental regulatory requirements and other information that impacts decisions as to station location, management has determined that it was not reasonably certain to exercise contract options and they are not included in the lease term.  Additionally, short-term leases and leases with variable lease costs are immaterial.  The Company reviews all options to extend, terminate, or otherwise modify its lease agreements to determine if changes are required to the right of use assets and liabilities.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As the implicit interest rate is not readily determinable in most of the Company's lease agreements, the Company uses its estimated secured incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.  </span></div><div><span><br/></span></div><div style="margin-bottom:6pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Lessor </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8212; We have various arrangements for certain spaces for food service and vending equipment under which we are the lessor.

ASU 2016-13 was subsequently modified by ASU 2018-19,  ASU 2019-04, ASU 2019-05, and ASU 2019-11.  This ASU changed the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life, which will result in timelier recognition of losses.  ASU 2016-13 and the associated modifications was effective for the Company on January 1, 2020 and required a modified retrospective approach with an adjustment at the beginning of year for any adjustment due to its adoption.  In applying ASC 326 at January 1, 2020, the Company calculated an adjustment to its estimated credit loss allowance and lowered the allowance by $1.1 million, which was credited to retained earnings under the modified retrospective approach.  The adjustment reflects the Company's changes in credit practices since its spin-of in 2013 which includes tighter applied credit terms and faster turnover of receivables resulting in a decrease to its estimated credit loss allowance as of January 1, 2020.  </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract".  This ASU aligns the accounting treatment for capitalizing implementation costs incurred by customers in cloud computing arrangements in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software.  This guidance was effective for the Company on January 1, 2020.  The amendments in this update were applied prospectively to all implementation costs incurred after the date of adoption.

This ASU eliminated, amended, and  added disclosure requirements for fair value measurements in Topic 820, including disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for level 3 measurements.  This guidance was effective for the Company on January 1, 2020.  The Company assessed the effect that this ASU had on our financial position, results of operations, and disclosures and determined that this update did not have a material impact on the Company's consolidated financial statements.

The ASU also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group.  This ASU is effective for the Company for the year beginning January 1, 2021, and early adoption is permitted.  The Company has assessed the effect that this ASU will have on our financial position, results of operations, and disclosures and has concluded that this update will not have a material impact on the Company's consolidated financial statements.</span></div>In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting".  This standard included option guidance for a limited period of time to help ease the burden in accounting for the effects of reference rate reform.  The new standard applies for all entities through December 31, 2022.  The Company has determined this standard has not had a material impact on the Company's consolidated financial statements.<span></span>

Due to the close proximity of the completion of the acquisition to the filing of this Form 10-K, the Company is unable to provide a preliminary purchase price allocation of the fair value of assets acquired and liabilities assumed in the transaction.  The Company will disclose a preliminary purchase price allocation in its Form 10-Q for the period ending March 31, 2021.  The financial results for QuickChek will be included in the Company's consolidated financial statements from the date of acquisition.  </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Also, on January 29, 2021, the Company refinanced its existing credit facility and issued new senior unsecured notes.  The Company entered into a new credit agreement that provides for a secured term loan of $400&#160;million (which was borrowed in full) and revolving credit commitments of $350&#160;million.  The term loan expires seven years from the date of issuance and the revolving credit facility matures in five years.  The secured term loan accrues interest at LIBOR plus 1.75%, subject to a LIBOR floor of 0.50% and the revolving credit facility accrues interest, when drawn, at LIBOR plus a range of 1.75% to 2.25% depending on a total debt to EBITDA ratio covenant.  As part of entering into the new credit agreement, the prior agreement which consisted of an ABL facility and term loan was fully repaid and retired.  </span></div>The senior unsecured notes were issued in an aggregate principal of $500&#160;million and bear interest at a rate of  3.750% per annum.  The notes mature on February 15, 2031, and interest is payable every February 15 and August beginning August 15, 2021.  These senior unsecured notes contain covenants that are essentially identical to the Company's other outstanding senior notes.<span></span>

Revenue is measured as the amounts of consideration we expect to receive in exchange for transferring goods or providing services.  Excise and sales tax that we collect where we have determined we are the principal in the transaction have been recorded as revenue on a jurisdiction-by-jurisdiction basis.  </span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#160;</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company enters into buy/sell and similar arrangements when petroleum products are held at one location but are needed at a different location.

Vendor allowances for price markdowns are credited to merchandise cost of goods sold during the period the related markdown is recognized. Volume rebates of merchandise are recorded as reductions to merchandise cost of goods sold when the merchandise qualifying for the rebate is sold. Slotting and stocking allowances received from a vendor are recorded as a reduction to cost of sales over the period covered by the agreement.<div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Petroleum product sales (at retail).</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">  For our retail store locations, the revenue related to petroleum product sales is recognized as the fuel is pumped to our customers.  The transaction price at the pump typically includes some portion of sales or excise taxes as levied in the respective jurisdictions.  Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid.  Our customers typically use a mixture of cash, checks, credit cards and debit cards to pay for our products as they are received.  We have accounts receivable from the various credit/debit card providers at any point in time related to product sales made on credit cards and debit cards.

Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid.

For scratch-off lottery tickets, we have determined we are the principal in the majority of the jurisdictions and therefore we record those sales on a gross basis.  We have some categories of merchandise (such as lotto tickets) where we are the agent and the revenues recorded for those transactions are our net commission only.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In June 2018 the Company initiated a loyalty pilot program through a limited number of its retail locations and was rolled out chain-wide in March 2019.  The customers earn rewards based on their spending or other promotional activities.  This program creates a performance obligation which requires us to defer a portion of sales revenue to the loyalty program participants until they redeem their rewards.  The rewards may be redeemed for free or discounted merchandise or cash discounts on fuel purchases.  Earned rewards expire after an account is inactive for a period of 90 days.  We recognize loyalty revenue when a customer redeems an earned reward.  Deferred revenue associated with Murphy Rewards is included in Trade accounts payable and accrued liabilities in our Consolidated Balance Sheet.  The deferred revenues recorded in 2020 and 2019 were immaterial.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">RINs sales.</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">  For the sale of RINs, we recognize revenue when the RIN is transferred to the counter-party and the sale is completed.

The accounts receivable primarily consists of amounts owed to the Company from credit card companies and by customers for wholesale sales of refined petroleum products. The allowance for doubtful accounts is the Company&#8217;s best estimate of the amount of probable credit losses on these receivables. The Company reviews this allowance for adequacy at least quarterly and bases its assessment on a combination of current information about its customers and historical write-off experience. Any trade accounts receivable balances written off are charged against the allowance for doubtful accounts.

<td class="text">PROPERTY, PLANT AND EQUIPMENT &#8211; Additions to property, plant and equipment, including renewals and betterments, are capitalized and recorded at cost. Certain marketing facilities are primarily depreciated using the composite straight-line method with depreciable lives ranging from 16 to 25 years. Gasoline stations, improvements to gasoline stations and other assets are depreciated over 3 to 50 years by individual unit on the straight-line method.  The Company capitalizes interest costs as a component of construction in progress on individually significant projects based on the weighted average interest rates incurred on its long-term borrowings.  Total interest cost capitalized was $1.4 million in 2020 and 2019, respectfully and $2.2 million in 2018.  The Company has undertaken like-kind exchange ("LKE") transactions under the Federal tax code in an effort to acquire and sell real and personal property in a tax efficient manner. The Company generally enters into forward transactions, in which property is sold and the proceeds are reinvested by acquiring similar property; and reverse transactions, in which property is acquired and similar property is subsequently sold.  A qualified LKE intermediary is used to facilitate these LKE transactions.  Proceeds from forward LKE transactions are held by the intermediary and are classified as restricted cash on the Company's balance sheet because the funds must be reinvested in similar properties.  If the acquisition of suitable LKE properties is not completed within 180 days of the sale of the Company-owned property, the proceeds are distributed to the Company by the intermediary and are reclassified as available cash and applicable income taxes are determined.  An exchange accommodation titleholder, a type of variable interest entity, is used to facilitate reverse like-kind exchanges. The acquired assets are held by the exchange accommodation titleholder until the exchange transactions are complete.  If the Company determines that it is the primary beneficiary of the exchange accommodation titleholder, the replacements assets held by the exchange accommodation titleholder are consolidated and recorded in Property, Plant and Equipment on the Consolidated Balance Sheets.  The unspent proceeds that are held in trust with the intermediary are recorded as noncurrent assets in the Consolidated Balance Sheet as the cash was restricted for the acquisition of property, plant and equipment.<span></span>

<td class="text">IMPAIRMENT OF ASSETS &#8211; Long-lived assets, which include property and equipment and finite-lived intangible assets, are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. A long-lived asset is not recoverable if its carrying amount exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. If a long-lived asset is not recoverable, an impairment loss is recognized for the amount by which the carrying amount of the long-lived asset exceeds its fair value, with fair value determined based on discounted estimated net cash flows or other appropriate methods.<span></span>

<td class="text">ASSET RETIREMENT OBLIGATIONS &#8211; The Company records a liability for asset retirement obligations (&#8220;ARO&#8221;) equal to the fair value of the estimated cost to retire an asset. The ARO liability is initially recorded in the period in which the obligation meets the definition of a liability, which is generally when the asset is placed in service. The ARO liability is estimated using existing regulatory requirements and anticipated future inflation rates. When the liability is initially recorded, the Company increases the carrying amount of the related long-lived asset by an amount equal to the original liability. The liability is increased over time to reflect the change in its present value, and the capitalized cost is depreciated over the useful life of the related long-lived asset. The Company reevaluates the adequacy of its recorded ARO liability at least annually. Actual costs of asset retirements such as dismantling service stations and site restoration are charged against the related liability. Any difference between costs incurred upon settlement of an asset retirement obligation and the recorded liability is recognized as a gain or loss in the Company&#8217;s Consolidated Income Statements.<span></span>

Under this method, income taxes are provided for amounts currently payable and for amounts deferred as tax assets and liabilities based on differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. Deferred income taxes are measured using the enacted tax rates that are assumed will be in effect when the differences reverse.

<td class="text">DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES &#8211; The fair value of a derivative instrument is recognized as an asset or liability in the Company&#8217;s Consolidated Balance Sheets. Upon entering into a derivative contract, the Company may designate the derivative as either a fair value hedge or a cash flow hedge, or decide that the contract is not a hedge, and therefore, recognize changes in the fair value of the contract in earnings. The Company documents the relationship between the derivative instrument designated as a hedge and the hedged items as well as its objective for risk management and strategy for use of the hedging instrument to manage the risk.  Derivative instruments designated as fair value or cash flow hedges are linked to specific assets and liabilities or to specific firm commitments or forecasted transactions.  The Company assesses at inception and on an ongoing basis whether a derivative instrument accounted for as a hedge is highly effective in offsetting changes in the fair value or cash flows of the hedged item.  A derivative that is not a highly effective hedge does not qualify for hedge accounting.  The change in the fair value of a qualifying fair value hedge is recorded in earnings along with the gain or loss on the hedged item.  The effective portion of the change in the fair value of a qualifying cash flow hedge is recorded in Accumulated other comprehensive income (AOCI) in the consolidated Balance Sheets until the hedged item is recognized currently in earnings.  If a derivative instrument no longer qualifies as a cash flow hedge and the underlying forecasted transaction is no longer probable of occurring, hedge accounting is discontinued and the gain or loss recorded in Accumulated other comprehensive income is recognized immediately in earnings.<span></span>

ASU 2016-13 was subsequently modified by ASU 2018-19,  ASU 2019-04, ASU 2019-05, and ASU 2019-11.  This ASU changed the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life, which will result in timelier recognition of losses.  ASU 2016-13 and the associated modifications was effective for the Company on January 1, 2020 and required a modified retrospective approach with an adjustment at the beginning of year for any adjustment due to its adoption.  In applying ASC 326 at January 1, 2020, the Company calculated an adjustment to its estimated credit loss allowance and lowered the allowance by $1.1 million, which was credited to retained earnings under the modified retrospective approach.

The Company assessed the effect that this ASU had on our financial position, results of operations, and disclosures and determined that this update did not have a material impact on the Company's consolidated financial statements.  See Note 12 "Financial Instruments and Risk Management" for additional information.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740):  Simplifying the Accounting for Income Taxes," which removes certain exceptions for: recognizing deferred taxes on investments, performing intraperiod allocation and calculating income taxes for interim periods. The ASU also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group.  This ASU is effective for the Company for the year beginning January 1, 2021, and early adoption is permitted.  The Company has assessed the effect that this ASU will have on our financial position, results of operations, and disclosures and has concluded that this update will not have a material impact on the Company's consolidated financial statements.</span></div>In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting".  This standard included option guidance for a limited period of time to help ease the burden in accounting for the effects of reference rate reform.  The new standard applies for all entities through December 31, 2022.  The Company has determined this standard has not had a material impact on the Company's consolidated financial statements.<span></span>

<td class="text">The Company determines if an arrangement is a lease or contains a lease at inception.  Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. The Company's leases have remaining lease terms of approximately 1 year to 20 years, which may include the option to extend the lease when it is reasonably certain the Company will exercise the option.  Most leases include one or more options to renew, with renewal terms that can extend the lease term from 5 to 20 years or more.  The exercise of lease renewal options is at the Company's sole discretion.  Due to the uncertainties of future markets, economic factors, technology changes, demographic shifts and behavior, environmental regulatory requirements and other information that impacts decisions as to station location, management has determined that it was not reasonably certain to exercise contract options and they are not included in the lease term.  Additionally, short-term leases and leases with variable lease costs are immaterial.  The Company reviews all options to extend, terminate, or otherwise modify its lease agreements to determine if changes are required to the right of use assets and liabilities.As the implicit interest rate is not readily determinable in most of the Company's lease agreements, the Company uses its estimated secured incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.<span></span>

The fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties. The table excludes Cash and cash equivalents, Accounts receivable-trade, and Trade accounts payable and accrued liabilities, all of which had fair values approximating carrying amounts. The fair value of Current and Long-term debt was estimated based on rates offered to the Company at that time for debt of the same maturities.
