NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note1 — Description of Business and Basis of Presentation

Description of business — Murphy USA Inc. (“Murphy USA” or the “Company”) markets refined products through a network of retail gasoline stations and to unbranded wholesale customers. Murphy USA’s owned retail stations are almost all located in close proximity to Walmart stores in 26 states and use the brand name Murphy USA®. Murphy USA also markets gasoline and other products at standalone stations under the Murphy Express brand. At September 30, 2017, Murphy USA had a total of 1,423 Company stations of which 1,154 were Murphy USA and 269 were Murphy Express.

Basis of Presentation — Murphy USA was incorporated in March 2013 and, in connection with its incorporation, Murphy USA issued 100 shares of common stock, par value $0.01 per share, to Murphy Oil Corporation (“Murphy Oil”) for $1.00. On August 30, 2013, Murphy USA was separated from Murphy Oil through the distribution of 100% of the common stock of Murphy USA to holders of Murphy Oil stock. 

In preparing the financial statements of Murphy USA in conformity with accounting principles generally accepted in the United States, management has made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Actual results may differ from these estimates.

In 2017, we revised our historical presentation of gains and losses on asset disposals and retirements, which are shown in our Consolidated Statements of Income as gain (loss) on sale of assets. This line item is currently, and will be prospectively, presented as a component of income from operations. Our accounting policy has been updated to reflect this presentation.

Interim Financial Information — The interim period financial information presented in these consolidated financial statements is unaudited and includes all known accruals and adjustments, in the opinion of management, necessary for a fair presentation of the consolidated financial position of Murphy USA and its results of operations and cash flows for the periods presented. All such adjustments are of a normal and recurring nature.

These interim consolidated financial statements should be read together with our audited financial statements for the years ended December 31, 2016, 2015 and 2014, included in our Annual Report on Form 10-K (File No. 001-35914), as filed with the Securities and Exchange Commission under the Securities Exchange Act of 1934 on February 22, 2017.

Recently Issued Accounting Standards—

In May 2014, the FASB issued ASU No. 2014-09 "Revenue from Contracts with Customers" ("ASU 2014-09"), which supersedes the revenue recognition requirements in the Accounting Standards Codification ("Codification") Topic 605, Revenue Recognition, and industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the new ASU 2014-09 is for companies to recognize revenue from the transfer of goods or services to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services. The Company will adopt ASU 2014-09 beginning January 1, 2018 using the modified retrospective approach applied to those contracts that were not completed at that date. Prior periods will not be retrospectively adjusted. The Company has completed its analysis to identify all revenue streams, and is currently determining the impact the ASU will have on these various revenue streams and the consolidated financial statements. The Company continues to evaluate the impact to our consolidated financial statements and related disclosures. The Company is in the process of updating our existing controls and processes to comply with the guidance.

Murphy USA Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company currently presents excise tax and other similar taxes collected on sales of refined products and remitted to governmental agencies on a gross basis, in both revenues and cost of petroleum products sold in the income statement.  ASU 2014-09 requires the Company to either analyze each tax on a jurisdiction-by-jurisdiction basis to determine if it is the principal in the transaction and continue to present the tax on a gross basis or elect to report all taxes on a net basis.  The Company expects to elect to assess all excise and other similar taxes on a jurisdiction-by-jurisdiction basis resulting in certain taxes to be presented on a net basis upon adoption of ASU 2014-09, thus reducing revenue in the income statement with no impact to net income or cash flows.  The Company does not expect the impact on reported revenue for the year ended December 31, 2018, or the quarters therein, to be material.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" (“ASU 2016-02”). ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets. Lessor accounting will remain similar to lessor accounting under previous GAAP, while aligning with the FASB’s new revenue recognition guidance. ASU 2016-02 is effective for the Company beginning January 1, 2019. Early adoption of ASU 2016-02 is permitted. The standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. While this ASU will have an impact on the Company's internal processes and controls and result in a change to the Company's accounting, the Company is still in the evaluation and information gathering stage of implementing the guidance and can not yet estimate the potential impact.

In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting", which amends the current stock compensation guidance. The amendments simplify the accounting for the taxes related to share-based payments, including adjustments to how excess tax benefits and a company’s payments for tax withholdings should be classified among other changes. The standard was effective for the Company on January 1, 2017.

The primary impact of adoption for the first nine months of 2017 was the recognition of $1.9 million of excess tax benefits in the provision for income taxes rather than paid-in-capital for the current period. Additional amendments to the accounting for income taxes and minimum statutory withholding tax requirements had no impact to retained earnings as of January 1, 2017, where the cumulative effect of these changes is required to be recorded. The Company elected to continue to estimate forfeitures expected to occur to determine the amount of compensation cost to be recognized in each period.

The Company elected to apply the presentation requirements for cash flows related to excess tax benefits prospectively as of January 1, 2017. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to any of the periods presented on the consolidated statement of cash flows, as such cash flows have historically been presented as a financing activity.

Senior Notes

On August 14, 2013, Murphy Oil USA, Inc., our primary operating subsidiary, issued 6.00% Senior Notes due 2023 (the “2023 Senior Notes”) in an aggregate principal amount of $500 million. The 2023 Senior Notes are fully and unconditionally guaranteed by Murphy USA, and are guaranteed by certain 100% owned subsidiaries that guarantee our credit facilities. The indenture governing the 2023 Senior Notes contains restrictive covenants that limit, among other things, the ability of Murphy USA, Murphy Oil USA, Inc. and the restricted subsidiaries to incur additional indebtedness or liens, dispose of assets, make certain restricted payments or investments, enter into transactions with affiliates or merge with or into other entities.

On April 25, 2017, Murphy Oil USA, Inc., issued $300 million of 5.625% Senior Notes due 2027 (the "2027 Senior Notes") under its existing shelf registration statement. The 2027 Senior Notes are fully and unconditionally guaranteed by Murphy USA, and are guaranteed by certain 100% owned subsidiaries that guarantee our credit facilities. The indenture governing the 2027 Senior Notes contains restrictive covenants that are essentially identical to the covenants for the 2023 Senior Notes.

The 2023 and 2027 Senior Notes and the guarantees rank equally with all of our and the guarantors’ existing and future senior unsecured indebtedness and effectively junior to our and the guarantors’ existing and future secured indebtedness (including indebtedness with respect to the credit facilities) to the extent of the value of the assets securing such indebtedness.  The 2023 and 2027 Senior Notes are structurally subordinated to all of the existing and future third-party liabilities, including trade payables, of our existing and future subsidiaries that do not guarantee the notes.

Credit Facilities and Term Loan

In March 2016, we amended and extended our existing credit agreement.  The credit agreement provides for a committed$450 million asset-based loan (ABL) facility (with availability subject to the borrowing base described below) and a$200 million term loan facility.  It also provides for a $150 millionuncommitted incremental facility. On March 10, 2016,Murphy Oil USA, Inc. borrowed$200 million under the term loan facility that has a four-year term. As of September 30, 2017, we have zero outstanding under our ABL facility.

The borrowing base is, at any time of determination, the amount (net of reserves) equal to the sum of:

•      100% of eligible cash at such time, plus

•      90% of eligible credit card receivables at such time, plus

•      90% of eligible investment grade accounts, plus

•      85% of eligible other accounts, plus

•      80% of eligible product supply/wholesale refined products inventory at such time, plus

•      75% of eligible retail refined products inventory at such time, plus

Murphy USA Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

The ABL facility includes a $200 million sublimit for the issuance of letters of credit. Letters of credit issued under the ABL facility reduce availability under the ABL facility.

Interest payable on the credit facilities is based on either:

• the London interbank offered rate, adjusted for statutory reserve requirements (the “Adjusted LIBO Rate”); or

• the Alternate Base Rate, which is defined as the highest of (a) the prime rate, (b) the federal funds effective rate from time to time plus 0.50% per annum and (c) the one-month Adjusted LIBO Rate plus 1.00% per annum,

plus, (A) in the case of Adjusted LIBO Rate borrowings, (i) with respect to the ABL facility, spreads ranging from 1.50% to 2.00% per annum depending on a total debt to EBITDA ratio under the ABL facility or (ii) with respect to the term loan facility, spreads ranging from 2.50% to 2.75% per annum depending on a total debt to EBITDA ratio and (B) in the case of Alternate Base Rate borrowings, (i) with respect to the ABL facility, spreads ranging from 0.50% to 1.00% per annum depending on total debt to EBITDA ratio or (ii) with respect to the term loan facility, spreads ranging from 1.50% to 1.75% per annum depending on a total debt to EBITDA ratio.

The interest rate period with respect to the Adjusted LIBO Rate interest rate option can be set at one, two, three, or six months as selected by us in accordance with the terms of the credit agreement.

We were obligated to make quarterly amortization payments on the outstanding principal amount of the term loan facility beginning on July 1, 2016 equal to 5% of the aggregate principal amount of term loans made on March 10, 2016, with the remaining balance payable on the scheduled maturity date of the term loan facility. Borrowings under the credit facilities are prepayable at our option without premium or penalty. We are also required to prepay the term loan facility with the net cash proceeds of certain asset sales or casualty events, subject to certain exceptions. The credit agreement also includes certain customary mandatory prepayment provisions with respect to the ABL facility.

The credit agreement contains certain covenants that limit, among other things, the ability of us and our subsidiaries to incur additional indebtedness or liens, to make certain investments, to enter into sale-leaseback transactions, to make certain restricted payments, to enter into consolidations, mergers or sales of material assets and other fundamental changes, to transact with affiliates, to enter into agreements restricting the ability of subsidiaries to incur liens or pay dividends, or to make certain accounting changes. In addition, the credit agreement requires us to maintain a minimum fixed charge coverage ratio of 1.0 to 1.0 when availability for at least three consecutive business days is less than the greater of (a) 17.5% of the lesser of the aggregate ABL facility commitments and the borrowing base and (b) $70,000,000 (including as of the most recent fiscal quarter end on the first date when availability is less than such amount), as well as a maximum secured total debt to EBITDA ratio of 4.5 to 1.0 at any time when term facility commitments or term loans are outstanding.  As of September 30, 2017, our fixed charge coverage ratio was 0.63; however, we had more than $100 million of availability under the ABL facility at that date so the fixed charge coverage ratio currently has no impact on our operations or liquidity. Our secured debt to EBITDA ratio as of September 30, 2017 was 0.23 to 1.0.         

The credit agreement contains restrictions on certain payments, including dividends, when availability under the credit agreement is less than or equal to the greater of $100 millionand 25% of the lesser of the revolving commitments and the borrowing base and our fixed charge coverage ratio is less than 1.0 to 1.0 (unless availability under the credit agreement is greater than $100 million and 40% of the lesser of the revolving commitments and the borrowing base). As of September 30, 2017, our ability to make restricted payments was not limited as our availability under the borrowing base was more than $100 million, while our fixed charge coverage ratio under our credit agreement was less than 1.0 to 1.0. As of December 31, 2016, we had a shortfall of approximately $304.1 million of our net income and retained earnings subject to such restrictions before the fixed charge coverage ratio under our credit agreement would exceed 1.0 to 1.0.

All obligations under the credit agreement are guaranteed by Murphy USA and the subsidiary guarantors party thereto, and all obligations under the credit agreement, including the guarantees of those obligations, are secured by certain assets of Murphy USA, Murphy Oil USA, Inc. and the guarantors party thereto.

Note4— Asset Retirement Obligations (ARO)

The majority of the ARO recognized by the Company at September 30, 2017 and December 31, 2016 related to the estimated costs to dismantle and abandon certain of its retail gasoline stations. The Company has not recorded an ARO for certain of its marketing assets because sufficient information is presently not available to estimate a range of potential settlement dates for the obligation. These assets are consistently being upgraded and are expected to be operational into the foreseeable future. In these cases, the obligation will be initially recognized in the period in which sufficient information exists to estimate the obligation.

A reconciliation of the beginning and ending aggregate carrying amount of the ARO is shown in the following table.

(Thousands of dollars)	September 30, 2017			December 31, 2016
Balance at beginning of period	$	26,200		$	24,345
Accretion expense	1,335			1,650
Liabilities incurred	230			379
Settlement of liabilities	$	(276	)	$	(174	)
Balance at end of period	$	27,489		$	26,200

The estimation of future ARO is based on a number of assumptions requiring professional judgment. The Company cannot predict the type of revisions to these assumptions that may be required in future periods due to the lack of availability of additional information.

Note5— Income Taxes

The effective tax rate is calculated as the amount of income tax expense divided by income before income tax expense (benefit). For the three and nine month periods ended September 30, 2017 and 2016, the Company’s effective tax rates were as follows:

	2017	2016
Three months ended September 30,	37.5%	36.6%
Nine months ended September 30,	36.2%	37.7%

The effective tax rate for the three and nine months ended September 30, 2017 and 2016 was higher than the U.S. Federal tax rate of 35% but is in line with our estimated effective tax rate of 38% for the remainder of the year.

The Company was included in Murphy Oil’s tax returns for the periods prior to the separation. The statute of several jurisdictions remains subject to audit by taxing authorities. As of September 30, 2017, the earliest year remaining open for Federal examination is 2014 and for the states it ranges from 2009-2012.  In addition to the pre-separation returns being open under statute, the federal and state tax returns post separation are also open under statute for examination. Although the Company believes that recorded liabilities for uncertain tax positions are adequate, additional gains or losses could occur in future periods from resolution of outstanding unsettled matters.

We adopted ASU 2016-09 on January 1, 2017, which requires the excess tax benefits or deficiencies to be reflected in the Consolidated Statements of Income as a component of the provision for income taxes whereas they previously were recognized in paid-in-capital. Total excess tax benefits recognized in the three and nine months ended September 30, 2017 was $0.0 million and $1.9 million, respectively.

Note6— Incentive Plans

2013 Long-Term Incentive Plan

Effective August 30, 2013, certain of our employees participate in the Murphy USA 2013 Long-Term Incentive Plan which was subsequently amended and restated effective as of February 8, 2017 (the “MUSA 2013 Plan”). The MUSA 2013 Plan authorizes the Executive Compensation Committee of our Board of Directors (“the Committee”) to grant non-qualified or incentive stock options, stock appreciation rights, stock awards (including restricted stock and restricted stock unit awards), cash awards, and performance awards to our employees. No more than 5.5 million shares of MUSA 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 “performance-based” award to any participant in any calendar year is $5 million.

On February 8, 2017, the Committee granted nonqualified stock options for 114,800 shares at an exercise price of $65.75 per share under the terms of the MUSA 2013 Plan.  The Black-Scholes valuation for these awards is $15.45 per option.  The Committee also awarded time-based restricted stock units and performance-based restricted stock units (performance units) to certain employees on the same date.  There were 29,075 time-based restricted units granted at an average grant date fair value of $65.41 along with 53,800 performance units.  Half of the performance units vest based on a 3-year return on average capital employed (ROACE) calculation and the other half vest based on a 3-year total shareholder return (TSR) calculation that compares MUSA to a group of 16 peer companies.  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.  For the TSR portion of the awards, the fair value was determined to be $94.51 per unit.  For the ROACE portion of the awards, the valuation will be based on the grant date fair value of $65.75 per unit and the number of awards will be periodically assessed to determine the probability of vesting. 

On February 8, 2017, the Committee also granted 50,075 time-based restricted stock units granted to certain employees with a grant date fair value of $65.75 per unit. 

2013 Stock Plan for Non-employee Directors

Effective August 8, 2013, Murphy USA adopted the 2013 Murphy USA Stock Plan for Non-employee Directors (the “Directors Plan”).  The directors for Murphy USA are compensated with a mixture of cash payments and equity-based awards.  Awards under the Directors Plan may be in the form of restricted stock, restricted stock units, stock options, or a combination thereof.  An aggregate of 500,000 shares of common stock shall be available for issuance of grants under the Directors Plan. 

During the first quarter of 2017, the Company issued 15,948 restricted stock units to its non-employee directors at a weighted average grant date fair value of $66.01 per share.  These shares vest in three years from the grant date. 

For the nine months ended September 30, 2017 and 2016, share based compensation was $4.7 million and $6.9 million, respectively.  The income tax benefit realized for the tax deductions from options exercised for the nine months ended September 30, 2017 and 2016 was $0.2 million and $1.7 million, respectively. 

Adoption of ASU 2016-09

On January 1, 2017, the Company adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which amended the current stock compensation guidance. As part of the adoption of this standard, the Company determined to leave its policy related to accounting for forfeitures based on estimates rather than changing to actual forfeitures. See Note 1 "Description of Business and Basis of Presentation" for information regarding the impact of adopting this standard for the Company.

Note 7— Financial Instruments and Risk Management

DERIVATIVE INSTRUMENTS — The Company makes limited use of derivative instruments to manage certain risks related to commodity prices. The use of derivative instruments for risk management is covered by operating policies and is closely monitored by the Company’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 (“NYMEX”). As of September 30, 2017, all current derivative activity is immaterial.

At September 30, 2017 and December 31, 2016, cash deposits of $2.8 million and $1.8 million related to commodity derivative contracts were reported in Prepaid expenses and other current assets in the Consolidated Balance Sheets, respectively. These cash deposits have not been used to increase the reported net assets or reduce the reported net liabilities on the derivative contracts at September 30, 2017 or December 31, 2016, respectively.

Note 8 – Earnings Per Share

Basic earnings per common share is computed by dividing net income available to common stockholders by the weighted average of common shares outstanding during the period.  Diluted earnings per common share adjusts basic earnings per common share for the effects of stock options and restricted stock in the periods where such items are dilutive. 

On January 25, 2016, the Company announced that it would proceed with an independent growth plan in which we will concentrate on acquiring land from third parties rather than acquiring land directly from Walmart. In conjunction with this announcement, the Board of Directors approved a strategic allocation of capital for the Company to pursue new additional growth opportunities and to undertake a share repurchase program of the Company's common stock. The Board authorized up to $500 million in total for this activity through December 31, 2017. For the nine months ended September 30, 2017, the Company acquired 2,252,828 shares of common stock for an average price of $67.47 per share including brokerage fees.  As of September 30, 2017, the Company has remaining authority of $24.7 million under our current program.

The following table provides a reconciliation of basic and diluted earnings per share computations for the three and nine months ended September 30, 2017 and 2016 (in thousands, except per share amounts):

	Three Months Ended September 30,				Nine Months Ended September 30,

For the reported periods, the number of time-based restricted stock units, performance based units and non-qualified stock options that are excluded due to their anti-dilutive nature is immaterial.

Note 10— Assets and Liabilities Measured at Fair Value

The Company carries certain assets and liabilities at fair value in its Consolidated Balance Sheets. 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.

Murphy USA Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

At the balance sheet date, the fair value of derivative contracts was determined using NYMEX quoted values but was immaterial.

The following table presents the carrying amounts and estimated fair values of financial instruments held by the Company at September 30, 2017 and December 31, 2016. 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, 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.

Note 11 — Contingencies

The Company’s operations and earnings have been and may be affected by various forms of governmental action. 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’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 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.

ENVIRONMENTAL MATTERS AND LEGAL MATTERS — 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 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.

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’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. The Company believes costs related to these sites will not have a material adverse effect on Murphy USA’s net income, financial condition or liquidity in a future period.

14

Murphy USA Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 September 30, 2017, 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. 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 September 30, 2017. 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 condition or liquidity in a future period.

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’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.

Other than as noted above, 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’s net income, financial condition or liquidity in a future period.

INSURANCE — 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 September 30, 2017, 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 accrued liability of $19.9 million will be sufficient to cover the related liability for all insurance claims and that the ultimate disposition of these claims will have no material effect on the Company’s financial position and results of operations.

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.

TAX MATTERS — 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.

OTHER MATTERS — 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 September 30, 2017, the Company had contingent liabilities of $15.4 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.

Note 12 — Business Segment

The Company's operations have one operating segment which is Marketing.  The operations include the sale of retail motor fuel products and convenience merchandise along with the wholesale and bulk sale capabilities of our Product Supply and Wholesale ("PS&W") group. As the primary purpose of the PS&W group is to support our retail operations and provide fuel for their daily operation, the bulk and wholesale fuel sales are secondary to the support functions performed by these groups. As such, they are all treated as one segment for reporting purposes as they sell the same products. This Marketing segment contains essentially all of the revenue generating functions of the Company. Results not included in the reportable segment include Corporate and Other Assets. The reportable segment was determined based on information reviewed by the Chief Operating Decision Maker (CODM).

Executive Overview

The following MD&A is intended to help the reader understand our results of operations and financial condition. This section is provided to supplement, and should be read in conjunction with, our consolidated financial statements and the accompanying notes to these financial statements contained elsewhere in this Quarterly Report on Form 10-Q, this MD&A section and the consolidated financial statements in our Annual Report on Form 10-K.  Our Form 10-K contains a discussion of matters not included within this document, such as disclosures regarding critical accounting policies and estimates, and contractual obligations. 

Our Business

We market refined products through a network of retail gasoline stations and to unbranded wholesale customers. Our owned retail stations are almost all located in close proximity to Walmart stores and use the brand name Murphy USA®. We also market gasoline and other products at standalone stations under the Murphy Express brand. At September 30, 2017, we had a total of 1,423 Company stations in 26 states, principally in the Southeast, Southwest and Midwest United States.  

Basis of Presentation

Murphy USA was incorporated in March 2013, and until the separation from Murphy Oil was completed on August 30, 2013, it had not commenced operations and had no material assets, liabilities or commitments.  The financial information presented in this Management’s Discussion and Analysis is derived from the consolidated financial statements of Murphy USA Inc. and its subsidiaries for all periods presented.

Trends Affecting Our Business

Our operations are significantly impacted by the gross margins we receive on our fuel sales. These gross margins are commodity-based, change daily and are volatile. While we expect our total fuel sales volumes to grow and the gross margins we realize on those sales to remain strong, 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, severe refinery mechanical failures for an extended period of time, and competition in the local markets in which we operate.

The cost of our main sales products, gasoline and diesel, is greatly impacted by the cost of crude oil in the United States.  Generally, rising prices for crude oil increase the Company’s cost for wholesale fuel products purchased.  When wholesale fuel costs rise, the Company is not always able to immediately pass these cost increases on to its retail customers at the pump, which in turn reduces the Company’s sales margin.  Also, rising prices tend to cause our customers to reduce discretionary fuel consumption, which generally reduces our fuel sales volumes.  Retail fuel margins were stronger in the current year quarter due to more favorable market conditions. PS&W results were stronger due to elements beyond normal seasonality, including the impact of hurricanes Harvey and Irma. The improvement in the current period was largely attributable to timing and inventory benefits due to rising wholesale prices, and to a lesser extent, modest improvement in the spot-to-rack differential.

In addition, our revenues are impacted by our ability to leverage our diverse supply infrastructure in pursuit of obtaining the lowest cost fuel supply available; for example, activities such as blending bulk fuel with ethanol and bio-diesel to capture and subsequently sell Renewable Identification Numbers (“RINs”).  Under the Energy Policy Act of 2005, the Environmental Protection Agency (“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 be sold in a market for RINs at then-prevailing prices. 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 affect the net impact we receive from RINs on a company-wide basis either favorably or unfavorably. Our business model does not depend on our ability to generate revenues from RINs.  Revenue from the sales of RINs is included in “Other operating revenues” in the Consolidated Statements of Income. 

As of September 30, 2017, we have $800 million of Senior Notes and $97 million of term loan outstanding. We believe that we will generate sufficient cash from operations to fund our ongoing operating requirements. 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. At September 30, 2017, we have additional available capacity under the committed $450 million credit facilities (subject to the borrowing base), together with capacity under a $150 million incremental uncommitted facility. 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.

On December 21, 2012, we signed an agreement with Walmart providing for the potential purchase of land to develop new Company stations located adjacent to existing Walmart stores in Walmart’s core market area covering the Southeast, Southwest and Midwest United States. The construction program is expected to be completed in 2017 relative to the 2012 sites. In connection with this agreement, we expect to incur additional station operating and depreciation expenses due to the addition of new stores.  The Company currently anticipates total capital expenditures (including purchases of Walmart properties and other land for future developments) for the full year 2017 to range from approximately $250 million to $300 million depending on how many new sites are developed.  We intend to fund the remainder of our capital program in 2017 primarily using operating cash flow but will supplement funding where necessary using borrowings under available credit facilities.  

We believe that our business will continue to grow in the future as we expect to build additional locations chosen by our real estate development team that have the characteristics we look for in a strong site. The pace of this growth is continually monitored by our management, and these plans can be altered based on operating cash flows generated and the availability of credit facilities.

We currently estimate our ongoing effective tax rate to be approximately 38.0% for the remainder of the year.

27

Seasonality

Our business has inherent seasonality due to the concentration of our retail sites in certain geographic areas, as well as customer activity behaviors during different seasons.  In general, sales volumes and operating incomes are typically highest in the second and third quarters during the summer activity months and lowest during the winter months.  As a result, operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

Business Segment

The Company has one operating segment which is Marketing.  This segment includes our retail marketing sites and product supply and wholesale assets. 

For additional operating segment information, see Note 20 “Business Segments” in the audited combined financial statements for the three year period ended December 31, 2016 included with our Annual Report on Form 10-K and Note 12 “Business Segment” in the accompanying unaudited consolidated financial statements for the three and nine months ended September 30, 2017.

Results of Operations

ConsolidatedResults

For the three month period ended September 30, 2017, the Company reported net income of $67.9 million, or $1.90 per diluted share, on revenue of $3.24 billion.  Net income was $45.5 million for the same period in 2016, or $1.16 per diluted share, on $3.04 billion in revenue.  The increase in quarterly net income was primarily driven by higher total margin contribution from both fuel and merchandise.

For the nine month period ended September 30, 2017, the Company reported net income of $120.4 million, or $3.29 per diluted share, on revenue of $9.45 billion. Net income was $177.7 million for the same period in 2016, or $4.44 per diluted share, on $8.54 billion in revenue. The decrease in year-to-date net income is primarily due to the inclusion of the gain on the disposition of the CAM pipeline in first quarter 2016.

ThreeMonthsEndedSeptember 30, 2017versus Three Months Ended September 30, 2016

Quarterly revenues for 2017 increased $193.6 million, or 6.4%, compared to the same quarter in 2016.  The higher revenues were caused by higher retail prices and increased store count in 2017, partially offset by a decrease in retail fuel volumes.

Total cost of sales increased $148.3 million, or 5.3%, compared to 2016.  In the current year quarter, higher fuel purchase costs in all areas were driven by higher wholesale prices and increased store count.

Station and other operating expenses increased $2.4 million, or 1.9%, from 2016.  Increased store count and higher retail fuel prices generated greater total payment fees during the 2017 quarter, which primarily contributed to the increase in station and operating expenses.

Selling, general and administrative (SG&A) expenses for 2017 increased $0.8 million, or 2.6%, from 2016.  The increase in SG&A costs is primarily due to timing of technology related expenses on a quarter-over-quarter basis.

The effective tax rate was 37.5% for the 2017 quarter and 36.6% for the 2016 quarter.  The effective tax rate for the current quarter is higher than the U.S. Federal tax rate of 35% but is in line with our estimated effective tax rate of 38% for the full year.

NineMonthsEndedSeptember 30, 2017versus Nine Months Ended September 30, 2016

Year-to-date revenues for 2017 increased $908.3 million, or 10.6%, compared to the same nine month period in 2016.  The higher revenues were caused by higher retail fuel prices and merchandise sales combined with increased store count in 2017.

28

Total cost of sales increased $877.1 million, or 11.3%, compared to 2016.  This increase is primarily due to higher fuel purchase costs in all areas in the 2017 period and increased store count in 2017.

Station and other operating expenses increased $14.6 million, or 4.0%, from 2016.  Higher store count in the current period generated greater payment fees and maintenance costs, which were the primary contributors to the increase in station and operating expenses.

Selling, general and administrative (SG&A) expenses for 2017 increased $6.6 million, or 7.0%, from 2016.  The increase in SG&A costs is primarily due to higher labor and employee benefit costs related to a previously announced restructuring charge combined with slightly increased headcount, as well as spending for technology projects.

The effective tax rate was 36.2% for the first nine months of 2017 and 37.7% for the 2016 period.  The current year effective tax rate is lower primarily due to the recognition of certain tax benefits.

Three Months EndedSeptember 30, 2017 versus Three Months EndedSeptember 30, 2016

Net income in the Marketing segmentfor 2017 increased $23.1 million compared to the2016 period. The primary driver was the 32.7% increase in total fuel contribution to 20.5 cpg in 2017. Additionally, merchandise gross margin increased 2.0% to $97.7 million.

30

Total revenues for the Marketing segment were approximately $3.2 billion for2017 and $3.0 billion for 2016.  Revenuesincluded excise taxes collected and remitted to government authorities of $489 million in2017 and $506 million in 2016. The primary cause of the uplift in revenues was a $0.25 per gallon increase in retail fuel price in the 2017 quarter.

Total fuel sales volumes per station were down 9.5% to 242,810gallons perstoremonth in the 2017 period from 268,259gallons perstoremonth in2016.  This decline is due to subdued retail demand, the temporary closure of five high-performing stores for raze and rebuild activity and hurricane-related impacts. Retail fuel margin increased 13.1% in the 2017 quarter to 15.5 cpg, compared to 13.7 cpg in the prior yearquarter.  Retail fuel margins increased in third quarter 2017 as falling wholesale product prices late in the period created a more favorable market structure and environment versus the consistently rising wholesale prices in third quarter 2016.

Total PS&W margin dollars, excluding RINs, were $3.6 million in the 2017 period compared to negative $29.0 million in 2016. The improvement in the current period was largely attributable to timing and inventory benefits due to rising wholesale prices, and to a lesser extent, modest improvement in the spot-to-rack differential.

The 2017 period includes the sale of RINs of $48.7 million compared to $48.0 million in 2016.  During the 2017 quarter, 59 million RINs were sold at an average selling price of $0.83 per RIN while the prior year quarter had sales of 54 million RINs at an average price of $0.89 per RIN.

Merchandise total sales increased 1.1%to$605.6 million in2017 from $599.0 million in 2016 and was primarily due to an increase in non-tobacco sales of 7.6% average per store month ("APSM"), offset by a decrease in tobacco products revenue of 6.7% APSM.Quarterly merchandise margins in 2017werehigher than2016. The increase in gross margin dollars of 2.0% in the current period was due primarily to continual turnover to new, high-demand products, in addition to per store improvements, partially offset by margin decreases on a per-store basis. As a result, total unit margins were up by 10 basis points from 16.0% in the prior period to 16.1% in the current quarter.

Station and otheroperating expenses increased $2.4 million in the current period compared to2016levels. Total operating expenses in 2017 were higher, reflecting increased payment fees and new store additions. On an APSM basis, expenses applicable to retail declined 5.4%, primarily because of lower labor costs in the period combined with lower maintenance per store due to timing of work performed.

Depreciation expense increased $3.4 million in the 2017period, an increase of 14.3%over the prior period. This increase was primarily caused by more stores operating in the 2017period compared to the prior yearperiod.

Selling, general and administrative (SG&A)expenses increased $0.8 million, or 2.6%, in2017. Thisincrease was due to timing of technology related expenses quarter-over-quarter.

Nine Months EndedSeptember 30, 2017 versus Nine Months EndedSeptember 30, 2016

Net income in the Marketing segmentfor 2017 decreased $58.5 million compared to the2016 period. The primary reason for this decline was no repeat of the gain from the disposition of the CAM pipeline in the prior year. This decline was partially offset by higher merchandise margins. Chain wide retail fuel sales volumes declined 0.9% to 3.1 billion gallons sold in 2017.

Total revenues for the Marketing segment were approximately $9.4 billion for2017 and $8.5 billion for 2016.  Revenuesincluded excise taxes collected and remitted to government authorities of $1.47 billion in2017 and $1.47 billion in 2016. The primary cause of the significant increase in revenues was a $0.26 per gallon increase in retail fuel price in the 2017 period.

Total fuel sales volumes per station were down 5.1% to 246,398gallons perstoremonth in the 2017 period from 259,681gallons perstoremonth in2016.  This decline is partially due to subdued retail demand combined with the temporary closure of 17 high-performing stores for a significant part of the period for raze and rebuild activity combined with hurricane-related impacts in the current period. Retail fuel margin increased 18.5% in the 2017 period to 14.1 cpg, compared to 11.9 cpg in the prior year.  Retail fuel margins increased in 2017 as volatility was more pronounced in the 2017 period compared to the same period in 2016.

Total PS&W margin dollars, excluding RINs, were negative $45.6 million in the 2017 period compared to negative $20.8 million in 2016. The decrease in the year-to-date period was largely caused by record-high gasoline inventories, subdued retail demand, and discounted pipeline space values.

31

The 2017 period includes the sale of RINs of $114.4 million compared to $130.7 million in 2016.  During the period, 172 million RINs were sold at an average selling price of $0.66 per RIN while the prior year had sales of 165 million RINs at an average price of $0.79 per RIN.

Merchandise total sales increased 1.5%to$1.78 billion in2017 from $1.75 billion in 2016 and was primarily due to an increase in non-tobacco sales of 5.2% APSM, offset by a decrease in tobacco products revenue of 5.5% APSM. Year-to-date merchandise margins in 2017werehigher than2016. The increase in gross margin dollars of 3.6% in the period was due primarily to more favorable pricing and improved promotional effectiveness, partially offset by margin decreases on a per-store basis. As a result, total unit margins were up by 30 basis points from 15.7% in the prior period to 16.0% in the current year.

Station and otheroperating expenses increased $14.6 million in the current period compared to2016levels. Total station and other operating expenses in 2017 were higher, reflecting increased payment fees and new store additions. On an APSM basis, expenses applicable to retail declined 3.5%, primarily because of lower labor costs in the period.

Depreciation expense increased $10.7 million in the 2017period, an increase of 15.7%over the prior period. This increase was primarily caused by more stores operating in the 2017period compared to the prior yearperiod.

Selling, general and administrative (SG&A)expenses increased $6.6 million, or 7.0%, in2017. Thisincrease was due to higher labor and employee benefit costs related to a previously announced restructuring charge combined with slightly increased headcount, as well as certain technology related costs.

Historically, the Company has used the APSM metric to represent certain data on a per site basis.  The APSM metric includes all stores open through the date of the calculation.  Other retailers have used same store sales (SSS) as their metric.  The table above shows the comparison of APSM to SSS for 3 specific items.  In most cases, the SSS metric is more favorable than the APSM metric.  The primary reason for this is that SSS does not include new stores that have been opened a short time and are still developing their customer base.  The difference between the APSM and SSS results highlights the impact of our growing mix of small store formats (e.g. 1200 sq. ft.) which have a higher mix of non-tobacco sales and a ramp up period on tobacco sales. 

32

The same store sales comparison includes aggregated individual store results for all stores open throughout both periods presented.  For all periods presented, the store must have been open for the entire calendar year to be included in the comparison.  Remodeled stores that remained open or were closed for just a very brief time (less than a month) during the period being compared remain in the same store sales calculation.  If a store is replaced, either at the same location (raze and rebuild) or relocated to a new location, it will typically be excluded from the calculation.  Newly constructed sites, including raze-and-rebuilds do not enter the calculation until they are open for each full calendar year for the periods being compared (open by January 1, 2016 for the sites being compared in the 2017 versus 2016 calculations). 

Corporate and other assets

After-tax results for Corporate and other assets decreased in the recently completed quarter, experiencing a loss of $7.9 million compared to a loss of $7.3 million in thethirdquarter of 2016.  Interest expense was higher in the current quarter by $2.5 million due primarily to the addition of the $300 million senior notes in the second quarter partially offset by lower interest cost related to the term loan.

After-tax results for Corporate and other assets improved in the recently completed quarter, experiencing a loss of $19.7 million compared to a loss of $20.9 million in 2016.  This improvement was due to the 2017 period containing certain income tax benefits related to the adoption of ASU 2016-09 and discrete state tax refunds received. Interest expense was higher in the current period by $4.1 million due primarily to the addition of the $300 million senior notes in the second quarter 2017.

Non-GAAP Measures

The following table sets forth the Company’s Adjusted EBITDA for the three and nine months ended September 30, 2017 and 2016.  EBITDA means net income (loss) plus net interest expense, plus income tax expense, depreciation and amortization, and Adjusted EBITDA adds back (i) 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, gain (loss) on sale of assets and other non-operating expense (income).  EBITDA and Adjusted EBITDA are not measures that are prepared in accordance with U.S. generally accepted accounting principles (GAAP).

We use this Adjusted EBITDA in our operational and financial decision-making, believing that such measure is useful to eliminate certain items in order to focus on what we deem to be a more reliable indicator of ongoing operating performance and our ability to generate cash flow from operations. Adjusted EBITDA is also used by many of our investors, research analysts, investment bankers, and lenders to assess our operating performance. 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. However, non-GAAP measures are not a substitute for GAAP disclosures, and Adjusted EBITDA may be prepared differently by us than by other companies using similarly titled non-GAAP measures.

The reconciliation of net income (loss) to EBITDA and Adjusted EBITDA follows:

Capital Resources and Liquidity

Significant Sources of Capital

We continue to have acommitted$450 million asset based loan facility (the “ABL facility”), which is subject to the remaining borrowing capacity of $295 million at September 30, 2017 (which can be utilized for working capital and other general corporate purposes, including supporting our operating model as described herein) and a $200 million term loan facility, as well as a $150 million incremental uncommitted facility. As of September 30, 2017, we had $97 million outstanding under our term loan and no amounts outstanding under our ABL.  See “Debt – Credit Facilities” below for the calculation of our borrowing base. 

We believe our short-term and long-term liquidity is adequate to fund not only our operations, but also our anticipated near-term and long-term funding requirements, including capital spending programs, execution of announced share repurchase programs, potential dividend payments, repayment of debt maturities and other amounts that may ultimately be paid in connection with contingencies.

Operating Activities

Net cash provided by operating activities was $166 million for theninemonths endedSeptember 30, 2017and$210 million for the comparable period in2016. The decrease was due primarily to an increase in inventories combined with a decrease in accounts payable. Net income decreased $57.3 million in 2017compared to the corresponding period in2016 due to no repeat of the gain on disposition of the CAM pipeline in 2016.

Investing Activities

For the ninemonths endedSeptember 30, 2017, cash required by investing activities was $205 million compared to $74 million in 2016. Thehigher investing cash use in the current period was primarily due tohigher capital expenditurespending in the current period to raze and rebuild retail locations while the prior year period also contained sales proceeds and changes in restricted cash.

Financing Activities

Financing activities in theninemonthsendedSeptember 30, 2017 provided cash of $54 million compared to cash required of $31 million in theninemonthsendedSeptember 30, 2016. Current period activity included issuing $300 million of our 2027 Senior Notes compared to the 2016 period when cash was generated from the borrowing of a $200 million term loan. The current period also included the repurchase of common shares of $152 million, as well as the repayment of $126 million of debt.

34

Share Repurchase Program

On January 25, 2016, the Company announced that its Board of Directors authorized up to $500 million for a share repurchase program of the Company’s common stock along with funding for new additional growth opportunities. Through the third quarter of 2017, the Company had purchased approximately $475 million of its common shares under this current repurchase authorization with $152 million of this amount being acquired during the first nine months of 2017. The timing and number of shares repurchased under the program was determined by management at its discretion, and depended on a number of factors, including compliance with the terms of our outstanding indebtedness, results of our internal shareholder valuation model, general market and business conditions and applicable legal requirements.  All purchases under this share repurchase program were funded through existing cash balances, operating cash flows, and other borrowings.  We do not expect this repurchase program to negatively impact our ability to fund future development projects such as building new stores.

As of September 30, 2017, there was $25 million remaining under the previously authorized program. Upon completing the existing repurchase program, the Company may elect to repurchase additional shares utilizing existing available cash balances if prices are favorable in management's opinion.

Debt

Our long-term debt at September 30, 2017 and December 31, 2016 are as set forth below:

(Thousands of dollars)	September 30, 2017			December 31, 2016

Senior Notes

On August 14, 2013, Murphy Oil USA, Inc., our primary operating subsidiary, issued 6.00% Senior Notes due 2023 (the “2023 Senior Notes”) in an aggregate principal amount of $500 million. The 2023 Senior Notes are fully and unconditionally guaranteed by Murphy USA, and are guaranteed by certain 100% owned subsidiaries that guarantee our credit facilities. The indenture governing the 2023 Senior Notes contains restrictive covenants that limit, among other things, the ability of Murphy USA, Murphy Oil USA, Inc. and the restricted subsidiaries to incur additional indebtedness or liens, dispose of assets, make certain restricted payments or investments, enter into transactions with affiliates or merge with or into other entities.

On April 25, 2017, Murphy Oil USA, Inc., our primary operating subsidiary, issued $300 million of 5.625% Senior Notes due 2027 (the "2027 Senior Notes") under its existing shelf registration statement. The 2027 Senior Notes are fully and unconditionally guaranteed by Murphy USA, and are guaranteed by certain 100% owned subsidiaries that guarantee our credit facilities. The indenture governing the 2027 Senior Notes contains restrictive covenants that are essentially identical to the covenants for the 2023 Senior Notes.

35

The 2023 and 2027 Senior Notes and the guarantees rank equally with all of our and the guarantors’ existing and future senior unsecured indebtedness and effectively junior to our and the guarantors’ existing and future secured indebtedness (including indebtedness with respect to the credit facilities) to the extent of the value of the assets securing such indebtedness.  The 2023 and 2027 Senior Notes are structurally subordinated to all of the existing and future third-party liabilities, including trade payables, of our existing and future subsidiaries that do not guarantee the notes.

Credit Facilities and Term Loan

In March 2016, we amended and extended our existing credit agreement.  The credit agreement provides for a committed$450 million ABL facility (with availability subject to the borrowing base described below) and a$200 million term loan facility.  It also provides for a $150 millionuncommitted  incremental  facility. On March 10, 2016,Murphy Oil USA, Inc. borrowed$200 million under the term loan facility that has a four-year term. As of September 30, 2017, we have zero outstanding under our ABL facility.

The borrowing base is, at any time of determination, the amount (net of reserves) equal to the sum of:

•      100% of eligible cash at such time, plus

•      90% of eligible credit card receivables at such time, plus

•      90% of eligible investment grade accounts, plus

•      85% of eligible other accounts, plus

•      80% of eligible product supply/wholesale refined products inventory at such time, plus

•      75% of eligible retail refined products inventory at such time, plus

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.

The ABL facility includes a $200 million sublimit for the issuance of letters of credit. Letters of credit issued under the ABL facility reduce availability under the ABL facility.

Interest payable on the credit facilities is based on either:

• the London interbank offered rate, adjusted for statutory reserve requirements (the “Adjusted LIBO Rate”); or

• the Alternate Base Rate, which is defined as the highest of (a) the prime rate, (b) the federal funds effective rate from time to time plus 0.50% per annum and (c) the one-month Adjusted LIBO Rate plus 1.00% per annum,

plus, (A) in the case of Adjusted LIBO Rate borrowings, (i) with respect to the ABL facility, spreads ranging from 1.50% to 2.00% per annum depending on a total debt to EBITDA ratio under the ABL facility or (ii) with respect to the term loan facility, spreads ranging from 2.50% to 2.75% per annum depending on a total debt to EBITDA ratio and (B) in the case of Alternate Base Rate borrowings, (i) with respect to the ABL facility, spreads ranging from 0.50% to 1.00% per annum depending on total debt to EBITDA ratio or (ii) with respect to the term loan facility, spreads ranging from 1.50% to 1.75% per annum depending on a total debt to EBITDA ratio.

The interest rate period with respect to the Adjusted LIBO Rate interest rate option can be set at one, two, three, or six months as selected by us in accordance with the terms of the credit agreement.

We are obligated to make quarterly amortization payments on the outstanding principal amount of the term loan facility equal to 5% of the aggregate principal amount of term loans made on March 10, 2016, with the remaining balance payable on the scheduled maturity date of the term loan facility. Borrowings under the credit facilities are prepayable at our option without premium or penalty. We are also required to prepay the term loan facility with the net cash proceeds of certain asset sales or casualty events, subject to certain exceptions. The credit agreement also includes certain customary mandatory prepayment provisions with respect to the ABL facility.

36

The credit agreement contains certain covenants that limit, among other things, the ability of us and our subsidiaries to incur additional indebtedness or liens, to make certain investments, to enter into sale-leaseback transactions, to make certain restricted payments, to enter into consolidations, mergers or sales of material assets and other fundamental changes, to transact with affiliates, to enter into agreements restricting the ability of subsidiaries to incur liens or pay dividends, or to make certain accounting changes. In addition, the credit agreement requires us to maintain a minimum fixed charge coverage ratio of a minimum of 1.0 to 1.0 when availability for at least three consecutive business days is less than the greater of (a) 17.5% of the lesser of the aggregate ABL facility commitments and the borrowing base and (b) $70,000,000 (including as of the most recent fiscal quarter end on the first date when availability is less than such amount), as well as a maximum secured total debt to EBITDA ratio of 4.5 to 1.0 at any time when the term loans are outstanding.  As of September 30, 2017, our fixed charge coverage ratio was 0.63; however, we had more than $100 million of availability under the ABL facility at that date so the fixed charge coverage ratio currently has no impact on our operations or liquidity. Our secured debt to EBITDA ratio as of September 30, 2017 was 0.23 to 1.0.

The credit agreement contains restrictions on certain payments, including dividends, when availability under the credit agreement is less than or equal to the greater of $100 millionand 25% of the lesser of the revolving commitments and the borrowing base and our fixed charge coverage ratio is less than 1.0 to 1.0 (unless availability under the credit agreement is greater than $100 million and 40% of the lesser of the revolving commitments and the borrowing base). As of September 30, 2017, our ability to make restricted payments was not limited as our availability under the borrowing base was more than $100 million, while our fixed charge coverage ratio under our credit agreement was less than 1.0 to 1.0. As of December 31, 2016, we had a shortfall of approximately $304.1 million of our net income and retained earnings subject to such restrictions before the fixed charge coverage ratio under our credit agreement would exceed 1.0 to 1.0.

All obligations under the credit agreement are guaranteed by Murphy USA and the subsidiary guarantors party thereto, and all obligations under the credit agreement, including the guarantees of those obligations, are secured by certain assets of Murphy USA, Murphy Oil USA, Inc. and the guarantors party thereto.

Capital Spending

Capital spending and investments in our Marketing segment relate primarily to the acquisition of land and the construction of new Company stations.  Our Marketing capital is also deployed to improve our existing sites, which we refer to as sustaining capital.  We also use sustaining capital in this business as needed to ensure reliability and continued performance of our sites.  We also invest in our Corporate and other assets segment. The following table outlines our capital spending and investments by segment for the three and ninemonth periods endedSeptember 30, 2017 and 2016:

	Three Months Ended September 30,				Nine Months Ended September 30,
(Thousands of dollars)	2017		2016		2017		2016

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Commodity Price Risk

We are exposed to market risks related to the volatility in the price of crude oil and refined products (primarily gasoline and diesel) used in our operations.  These fluctuations can affect our revenues and purchases, as well as the cost of operating, investing and financing activities.  We make limited use of derivative instruments to manage certain risks related to commodity prices.  The use of derivative instruments for risk management is covered by operating policies and is closely monitored by our middle-office function and the Company’s senior management.

As described in Note7“Financial Instruments and Risk Management” in the accompanying unauditedconsolidatedfinancial statements, there were short-term commodity derivative contracts in place atSeptember 30, 2017to hedge the purchase price of refined products. A 10% increase or decrease in the respective benchmark price of the commodities underlying these derivative contracts would havebeen immaterial to the Company. Changes in the fair value of these derivative contracts generally offset the changes in the value for an equivalent volume of these products.

For additional information about our use of derivative instruments, see Note13 “Financial Instruments and Risk Management” inouraudited combined financial statements for the threeyear period endedDecember 31, 2016 included in the Form 10-K and Note7 “Financial Instruments and Risk Management” in the accompanying unauditedconsolidatedfinancial statements for theninemonths endedSeptember 30, 2017.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures.

Our management has evaluated, with the participation ofour principal executiveand financial officers, the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15 under the Securities Exchange Act of 1934) as of the end of the period covered by this report, and has concluded that our disclosure controls and procedures were effective as ofSeptember 30, 2017.

Internal Control over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting during the quarter ended September 30, 2017 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting. 

PART II –OTHER INFORMATION

ITEM 1.LEGAL PROCEEDINGS

As of September 30, 2017, the Company was engaged in a number of legal proceedings, all of which the Company considers routine and incidental to its business.  See Note 11 ”Contingencies” in the accompanying consolidated financial statements.  Based on information currently available to the Company, the ultimate resolution of environmental and legal matters referred to in this Item is not expected to have a material adverse effect on the Company’s net income, financial condition or liquidity in a future period.

The Company was contacted by the State of Mississippi to settle alleged violations of the state's Petroleum Underground Storage Tank system requirements at several of the Company's facilities. Based on discussions to date, the civil penalty is anticipated to be approximately $130,000. We are negotiating this matter with the state's Department of Environmental Quality in order to establish a consent agreement and resolve any allegations of non-compliance. We do not anticipate that the resolution of this matter will have a material impact on our results of operations or financial condition.

39

ITEM 1A.RISK FACTORS

Our business, results of operations, cash flows and financial condition involve various risks and uncertainties. These risk factors are discussed under the caption “Risk Factors” in our Annual Report on Form 10-K.  We have not identified any additional risk factors not previously disclosed in the Form 10-K.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Description of Business and Basis of Presentation

Description of Business and Basis of Presentation

Description of business — Murphy USA Inc. (“Murphy USA” or the “Company”) markets refined products through a network of retail gasoline stations and to unbranded wholesale customers. Murphy USA’s owned retail stations are almost all located in close proximity to Walmart stores in 26 states and use the brand name Murphy USA®. Murphy USA also markets gasoline and other products at standalone stations under the Murphy Express brand. At September 30, 2017, Murphy USA had a total of 1,423 Company stations of which 1,154 were Murphy USA and 269 were Murphy Express.

Basis of Presentation — Murphy USA was incorporated in March 2013 and, in connection with its incorporation, Murphy USA issued 100 shares of common stock, par value $0.01 per share, to Murphy Oil Corporation (“Murphy Oil”) for $1.00. On August 30, 2013, Murphy USA was separated from Murphy Oil through the distribution of 100% of the common stock of Murphy USA to holders of Murphy Oil stock. 

In preparing the financial statements of Murphy USA in conformity with accounting principles generally accepted in the United States, management has made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Actual results may differ from these estimates.

In 2017, we revised our historical presentation of gains and losses on asset disposals and retirements, which are shown in our Consolidated Statements of Income as gain (loss) on sale of assets. This line item is currently, and will be prospectively, presented as a component of income from operations. Our accounting policy has been updated to reflect this presentation.

Interim Financial Information — The interim period financial information presented in these consolidated financial statements is unaudited and includes all known accruals and adjustments, in the opinion of management, necessary for a fair presentation of the consolidated financial position of Murphy USA and its results of operations and cash flows for the periods presented. All such adjustments are of a normal and recurring nature.

These interim consolidated financial statements should be read together with our audited financial statements for the years ended December 31, 2016, 2015 and 2014, included in our Annual Report on Form 10-K (File No. 001-35914), as filed with the Securities and Exchange Commission under the Securities Exchange Act of 1934 on February 22, 2017.

Recently Issued Accounting Standards—

In May 2014, the FASB issued ASU No. 2014-09 "Revenue from Contracts with Customers" ("ASU 2014-09"), which supersedes the revenue recognition requirements in the Accounting Standards Codification ("Codification") Topic 605, Revenue Recognition, and industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the new ASU 2014-09 is for companies to recognize revenue from the transfer of goods or services to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services. The Company will adopt ASU 2014-09 beginning January 1, 2018 using the modified retrospective approach applied to those contracts that were not completed at that date. Prior periods will not be retrospectively adjusted. The Company has completed its analysis to identify all revenue streams, and is currently determining the impact the ASU will have on these various revenue streams and the consolidated financial statements. The Company continues to evaluate the impact to our consolidated financial statements and related disclosures. The Company is in the process of updating our existing controls and processes to comply with the guidance.

The Company currently presents excise tax and other similar taxes collected on sales of refined products and remitted to governmental agencies on a gross basis, in both revenues and cost of petroleum products sold in the income statement.  ASU 2014-09 requires the Company to either analyze each tax on a jurisdiction-by-jurisdiction basis to determine if it is the principal in the transaction and continue to present the tax on a gross basis or elect to report all taxes on a net basis.  The Company expects to elect to assess all excise and other similar taxes on a jurisdiction-by-jurisdiction basis resulting in certain taxes to be presented on a net basis upon adoption of ASU 2014-09, thus reducing revenue in the income statement with no impact to net income or cash flows.  The Company does not expect the impact on reported revenue for the year ended December 31, 2018, or the quarters therein, to be material.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" (“ASU 2016-02”). ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets. Lessor accounting will remain similar to lessor accounting under previous GAAP, while aligning with the FASB’s new revenue recognition guidance. ASU 2016-02 is effective for the Company beginning January 1, 2019. Early adoption of ASU 2016-02 is permitted. The standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. While this ASU will have an impact on the Company's internal processes and controls and result in a change to the Company's accounting, the Company is still in the evaluation and information gathering stage of implementing the guidance and can not yet estimate the potential impact.

In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting", which amends the current stock compensation guidance. The amendments simplify the accounting for the taxes related to share-based payments, including adjustments to how excess tax benefits and a company’s payments for tax withholdings should be classified among other changes. The standard was effective for the Company on January 1, 2017.

The primary impact of adoption for the first nine months of 2017 was the recognition of $1.9 million of excess tax benefits in the provision for income taxes rather than paid-in-capital for the current period. Additional amendments to the accounting for income taxes and minimum statutory withholding tax requirements had no impact to retained earnings as of January 1, 2017, where the cumulative effect of these changes is required to be recorded. The Company elected to continue to estimate forfeitures expected to occur to determine the amount of compensation cost to be recognized in each period.

The Company elected to apply the presentation requirements for cash flows related to excess tax benefits prospectively as of January 1, 2017. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to any of the periods presented on the consolidated statement of cash flows, as such cash flows have historically been presented as a financing activity.

Senior Notes

On August 14, 2013, Murphy Oil USA, Inc., our primary operating subsidiary, issued 6.00% Senior Notes due 2023 (the “2023 Senior Notes”) in an aggregate principal amount of $500 million. The 2023 Senior Notes are fully and unconditionally guaranteed by Murphy USA, and are guaranteed by certain 100% owned subsidiaries that guarantee our credit facilities. The indenture governing the 2023 Senior Notes contains restrictive covenants that limit, among other things, the ability of Murphy USA, Murphy Oil USA, Inc. and the restricted subsidiaries to incur additional indebtedness or liens, dispose of assets, make certain restricted payments or investments, enter into transactions with affiliates or merge with or into other entities.

On April 25, 2017, Murphy Oil USA, Inc., issued $300 million of 5.625% Senior Notes due 2027 (the "2027 Senior Notes") under its existing shelf registration statement. The 2027 Senior Notes are fully and unconditionally guaranteed by Murphy USA, and are guaranteed by certain 100% owned subsidiaries that guarantee our credit facilities. The indenture governing the 2027 Senior Notes contains restrictive covenants that are essentially identical to the covenants for the 2023 Senior Notes.

The 2023 and 2027 Senior Notes and the guarantees rank equally with all of our and the guarantors’ existing and future senior unsecured indebtedness and effectively junior to our and the guarantors’ existing and future secured indebtedness (including indebtedness with respect to the credit facilities) to the extent of the value of the assets securing such indebtedness.  The 2023 and 2027 Senior Notes are structurally subordinated to all of the existing and future third-party liabilities, including trade payables, of our existing and future subsidiaries that do not guarantee the notes.

Credit Facilities and Term Loan

In March 2016, we amended and extended our existing credit agreement.  The credit agreement provides for a committed$450 million asset-based loan (ABL) facility (with availability subject to the borrowing base described below) and a$200 million term loan facility.  It also provides for a $150 millionuncommitted incremental facility. On March 10, 2016,Murphy Oil USA, Inc. borrowed$200 million under the term loan facility that has a four-year term. As of September 30, 2017, we have zero outstanding under our ABL facility.

The borrowing base is, at any time of determination, the amount (net of reserves) equal to the sum of:

•      100% of eligible cash at such time, plus

•      90% of eligible credit card receivables at such time, plus

•      90% of eligible investment grade accounts, plus

•      85% of eligible other accounts, plus

•      80% of eligible product supply/wholesale refined products inventory at such time, plus

•      75% of eligible retail refined products inventory at such time, plus

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.

The ABL facility includes a $200 million sublimit for the issuance of letters of credit. Letters of credit issued under the ABL facility reduce availability under the ABL facility.

Interest payable on the credit facilities is based on either:

• the London interbank offered rate, adjusted for statutory reserve requirements (the “Adjusted LIBO Rate”); or

• the Alternate Base Rate, which is defined as the highest of (a) the prime rate, (b) the federal funds effective rate from time to time plus 0.50% per annum and (c) the one-month Adjusted LIBO Rate plus 1.00% per annum,

plus, (A) in the case of Adjusted LIBO Rate borrowings, (i) with respect to the ABL facility, spreads ranging from 1.50% to 2.00% per annum depending on a total debt to EBITDA ratio under the ABL facility or (ii) with respect to the term loan facility, spreads ranging from 2.50% to 2.75% per annum depending on a total debt to EBITDA ratio and (B) in the case of Alternate Base Rate borrowings, (i) with respect to the ABL facility, spreads ranging from 0.50% to 1.00% per annum depending on total debt to EBITDA ratio or (ii) with respect to the term loan facility, spreads ranging from 1.50% to 1.75% per annum depending on a total debt to EBITDA ratio.

The interest rate period with respect to the Adjusted LIBO Rate interest rate option can be set at one, two, three, or six months as selected by us in accordance with the terms of the credit agreement.

We were obligated to make quarterly amortization payments on the outstanding principal amount of the term loan facility beginning on July 1, 2016 equal to 5% of the aggregate principal amount of term loans made on March 10, 2016, with the remaining balance payable on the scheduled maturity date of the term loan facility. Borrowings under the credit facilities are prepayable at our option without premium or penalty. We are also required to prepay the term loan facility with the net cash proceeds of certain asset sales or casualty events, subject to certain exceptions. The credit agreement also includes certain customary mandatory prepayment provisions with respect to the ABL facility.

The credit agreement contains certain covenants that limit, among other things, the ability of us and our subsidiaries to incur additional indebtedness or liens, to make certain investments, to enter into sale-leaseback transactions, to make certain restricted payments, to enter into consolidations, mergers or sales of material assets and other fundamental changes, to transact with affiliates, to enter into agreements restricting the ability of subsidiaries to incur liens or pay dividends, or to make certain accounting changes. In addition, the credit agreement requires us to maintain a minimum fixed charge coverage ratio of 1.0 to 1.0 when availability for at least three consecutive business days is less than the greater of (a) 17.5% of the lesser of the aggregate ABL facility commitments and the borrowing base and (b) $70,000,000 (including as of the most recent fiscal quarter end on the first date when availability is less than such amount), as well as a maximum secured total debt to EBITDA ratio of 4.5 to 1.0 at any time when term facility commitments or term loans are outstanding.  As of September 30, 2017, our fixed charge coverage ratio was 0.63; however, we had more than $100 million of availability under the ABL facility at that date so the fixed charge coverage ratio currently has no impact on our operations or liquidity. Our secured debt to EBITDA ratio as of September 30, 2017 was 0.23 to 1.0.         

The credit agreement contains restrictions on certain payments, including dividends, when availability under the credit agreement is less than or equal to the greater of $100 millionand 25% of the lesser of the revolving commitments and the borrowing base and our fixed charge coverage ratio is less than 1.0 to 1.0 (unless availability under the credit agreement is greater than $100 million and 40% of the lesser of the revolving commitments and the borrowing base). As of September 30, 2017, our ability to make restricted payments was not limited as our availability under the borrowing base was more than $100 million, while our fixed charge coverage ratio under our credit agreement was less than 1.0 to 1.0. As of December 31, 2016, we had a shortfall of approximately $304.1 million of our net income and retained earnings subject to such restrictions before the fixed charge coverage ratio under our credit agreement would exceed 1.0 to 1.0.

All obligations under the credit agreement are guaranteed by Murphy USA and the subsidiary guarantors party thereto, and all obligations under the credit agreement, including the guarantees of those obligations, are secured by certain assets of Murphy USA, Murphy Oil USA, Inc. and the guarantors party thereto.

Asset Retirement Obligations (ARO)

Asset Retirement Obligations (ARO)

The majority of the ARO recognized by the Company at September 30, 2017 and December 31, 2016 related to the estimated costs to dismantle and abandon certain of its retail gasoline stations. The Company has not recorded an ARO for certain of its marketing assets because sufficient information is presently not available to estimate a range of potential settlement dates for the obligation. These assets are consistently being upgraded and are expected to be operational into the foreseeable future. In these cases, the obligation will be initially recognized in the period in which sufficient information exists to estimate the obligation.

A reconciliation of the beginning and ending aggregate carrying amount of the ARO is shown in the following table.

(Thousands of dollars)	September 30, 2017			December 31, 2016
Balance at beginning of period	$	26,200		$	24,345
Accretion expense	1,335			1,650
Liabilities incurred	230			379
Settlement of liabilities	$	(276	)	$	(174	)
Balance at end of period	$	27,489		$	26,200

The estimation of future ARO is based on a number of assumptions requiring professional judgment. The Company cannot predict the type of revisions to these assumptions that may be required in future periods due to the lack of availability of additional information.

Income Taxes

Income Taxes

The effective tax rate is calculated as the amount of income tax expense divided by income before income tax expense (benefit). For the three and nine month periods ended September 30, 2017 and 2016, the Company’s effective tax rates were as follows:

	2017	2016
Three months ended September 30,	37.5%	36.6%
Nine months ended September 30,	36.2%	37.7%

The effective tax rate for the three and nine months ended September 30, 2017 and 2016 was higher than the U.S. Federal tax rate of 35% but is in line with our estimated effective tax rate of 38% for the remainder of the year.

The Company was included in Murphy Oil’s tax returns for the periods prior to the separation. The statute of several jurisdictions remains subject to audit by taxing authorities. As of September 30, 2017, the earliest year remaining open for Federal examination is 2014 and for the states it ranges from 2009-2012.  In addition to the pre-separation returns being open under statute, the federal and state tax returns post separation are also open under statute for examination. Although the Company believes that recorded liabilities for uncertain tax positions are adequate, additional gains or losses could occur in future periods from resolution of outstanding unsettled matters.

We adopted ASU 2016-09 on January 1, 2017, which requires the excess tax benefits or deficiencies to be reflected in the Consolidated Statements of Income as a component of the provision for income taxes whereas they previously were recognized in paid-in-capital. Total excess tax benefits recognized in the three and nine months ended September 30, 2017 was $0.0 million and $1.9 million, respectively.

Incentive Plans

2013 Long-Term Incentive Plan

Effective August 30, 2013, certain of our employees participate in the Murphy USA 2013 Long-Term Incentive Plan which was subsequently amended and restated effective as of February 8, 2017 (the “MUSA 2013 Plan”). The MUSA 2013 Plan authorizes the Executive Compensation Committee of our Board of Directors (“the Committee”) to grant non-qualified or incentive stock options, stock appreciation rights, stock awards (including restricted stock and restricted stock unit awards), cash awards, and performance awards to our employees. No more than 5.5 million shares of MUSA 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 “performance-based” award to any participant in any calendar year is $5 million.

On February 8, 2017, the Committee granted nonqualified stock options for 114,800 shares at an exercise price of $65.75 per share under the terms of the MUSA 2013 Plan.  The Black-Scholes valuation for these awards is $15.45 per option.  The Committee also awarded time-based restricted stock units and performance-based restricted stock units (performance units) to certain employees on the same date.  There were 29,075 time-based restricted units granted at an average grant date fair value of $65.41 along with 53,800 performance units.  Half of the performance units vest based on a 3-year return on average capital employed (ROACE) calculation and the other half vest based on a 3-year total shareholder return (TSR) calculation that compares MUSA to a group of 16 peer companies.  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.  For the TSR portion of the awards, the fair value was determined to be $94.51 per unit.  For the ROACE portion of the awards, the valuation will be based on the grant date fair value of $65.75 per unit and the number of awards will be periodically assessed to determine the probability of vesting. 

On February 8, 2017, the Committee also granted 50,075 time-based restricted stock units granted to certain employees with a grant date fair value of $65.75 per unit. 

2013 Stock Plan for Non-employee Directors

Effective August 8, 2013, Murphy USA adopted the 2013 Murphy USA Stock Plan for Non-employee Directors (the “Directors Plan”).  The directors for Murphy USA are compensated with a mixture of cash payments and equity-based awards.  Awards under the Directors Plan may be in the form of restricted stock, restricted stock units, stock options, or a combination thereof.  An aggregate of 500,000 shares of common stock shall be available for issuance of grants under the Directors Plan. 

During the first quarter of 2017, the Company issued 15,948 restricted stock units to its non-employee directors at a weighted average grant date fair value of $66.01 per share.  These shares vest in three years from the grant date. 

For the nine months ended September 30, 2017 and 2016, share based compensation was $4.7 million and $6.9 million, respectively.  The income tax benefit realized for the tax deductions from options exercised for the nine months ended September 30, 2017 and 2016 was $0.2 million and $1.7 million, respectively. 

Adoption of ASU 2016-09

On January 1, 2017, the Company adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which amended the current stock compensation guidance. As part of the adoption of this standard, the Company determined to leave its policy related to accounting for forfeitures based on estimates rather than changing to actual forfeitures. See Note 1 "Description of Business and Basis of Presentation" for information regarding the impact of adopting this standard for the Company.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per common share is computed by dividing net income available to common stockholders by the weighted average of common shares outstanding during the period.  Diluted earnings per common share adjusts basic earnings per common share for the effects of stock options and restricted stock in the periods where such items are dilutive. 

On January 25, 2016, the Company announced that it would proceed with an independent growth plan in which we will concentrate on acquiring land from third parties rather than acquiring land directly from Walmart. In conjunction with this announcement, the Board of Directors approved a strategic allocation of capital for the Company to pursue new additional growth opportunities and to undertake a share repurchase program of the Company's common stock. The Board authorized up to $500 million in total for this activity through December 31, 2017. For the nine months ended September 30, 2017, the Company acquired 2,252,828 shares of common stock for an average price of $67.47 per share including brokerage fees.  As of September 30, 2017, the Company has remaining authority of $24.7 million under our current program.

The following table provides a reconciliation of basic and diluted earnings per share computations for the three and nine months ended September 30, 2017 and 2016 (in thousands, except per share amounts):

	Three Months Ended September 30,				Nine Months Ended September 30,

Earnings per common share	$	1.92	$	1.17	$	3.32	$	4.47

Earnings per common share - assuming dilution:
Net income (loss) per share - diluted
Net income (loss) attributable to common stockholders	$	67,887	$	45,491	$	120,424	$	177,675

Earnings per common share assuming dilution	$	1.90	$	1.16	$	3.29	$	4.44

We have excluded from the earnings-per-share calculation certain stock options and shares that are considered to be anti-dilutive under the treasury stock method. For the reported periods, the number of time-based restricted stock units, performance based units and non-qualified stock options that are excluded due to their anti-dilutive nature is immaterial.

Fair Value Disclosures [Abstract]

Assets and Liabilities Measure at Fair Value

Assets and Liabilities Measured at Fair Value

The Company carries certain assets and liabilities at fair value in its Consolidated Balance Sheets. 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.

At the balance sheet date, the fair value of derivative contracts was determined using NYMEX quoted values but was immaterial.

The following table presents the carrying amounts and estimated fair values of financial instruments held by the Company at September 30, 2017 and December 31, 2016. 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, 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.

Contingencies

Sep. 30, 2017

Commitments and Contingencies Disclosure [Abstract]

Contingencies

Contingencies

The Company’s operations and earnings have been and may be affected by various forms of governmental action. 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’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 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.

ENVIRONMENTAL MATTERS AND LEGAL MATTERS — 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 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.

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’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. The Company believes costs related to these sites will not have a material adverse effect on Murphy USA’s net income, financial condition or liquidity in a future period.

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 September 30, 2017, 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. 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 September 30, 2017. 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 condition or liquidity in a future period.

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’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.

Other than as noted above, 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’s net income, financial condition or liquidity in a future period.

INSURANCE — 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 September 30, 2017, 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 accrued liability of $19.9 million will be sufficient to cover the related liability for all insurance claims and that the ultimate disposition of these claims will have no material effect on the Company’s financial position and results of operations.

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.

TAX MATTERS — 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.

OTHER MATTERS — 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 September 30, 2017, the Company had contingent liabilities of $15.4 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.

Business Segment

The Company's operations have one operating segment which is Marketing.  The operations include the sale of retail motor fuel products and convenience merchandise along with the wholesale and bulk sale capabilities of our Product Supply and Wholesale ("PS&W") group. As the primary purpose of the PS&W group is to support our retail operations and provide fuel for their daily operation, the bulk and wholesale fuel sales are secondary to the support functions performed by these groups. As such, they are all treated as one segment for reporting purposes as they sell the same products. This Marketing segment contains essentially all of the revenue generating functions of the Company. Results not included in the reportable segment include Corporate and Other Assets. The reportable segment was determined based on information reviewed by the Chief Operating Decision Maker (CODM).

Description of Business and Basis of Presentation (Policies)

9 Months Ended

Sep. 30, 2017

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation — Murphy USA was incorporated in March 2013 and, in connection with its incorporation, Murphy USA issued 100 shares of common stock, par value $0.01 per share, to Murphy Oil Corporation (“Murphy Oil”) for $1.00. On August 30, 2013, Murphy USA was separated from Murphy Oil through the distribution of 100% of the common stock of Murphy USA to holders of Murphy Oil stock. 

In preparing the financial statements of Murphy USA in conformity with accounting principles generally accepted in the United States, management has made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Actual results may differ from these estimates.

Recently Issued Accounting Standards

Recently Issued Accounting Standards—

In May 2014, the FASB issued ASU No. 2014-09 "Revenue from Contracts with Customers" ("ASU 2014-09"), which supersedes the revenue recognition requirements in the Accounting Standards Codification ("Codification") Topic 605, Revenue Recognition, and industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the new ASU 2014-09 is for companies to recognize revenue from the transfer of goods or services to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services. The Company will adopt ASU 2014-09 beginning January 1, 2018 using the modified retrospective approach applied to those contracts that were not completed at that date. Prior periods will not be retrospectively adjusted. The Company has completed its analysis to identify all revenue streams, and is currently determining the impact the ASU will have on these various revenue streams and the consolidated financial statements. The Company continues to evaluate the impact to our consolidated financial statements and related disclosures. The Company is in the process of updating our existing controls and processes to comply with the guidance.

The Company currently presents excise tax and other similar taxes collected on sales of refined products and remitted to governmental agencies on a gross basis, in both revenues and cost of petroleum products sold in the income statement.  ASU 2014-09 requires the Company to either analyze each tax on a jurisdiction-by-jurisdiction basis to determine if it is the principal in the transaction and continue to present the tax on a gross basis or elect to report all taxes on a net basis.  The Company expects to elect to assess all excise and other similar taxes on a jurisdiction-by-jurisdiction basis resulting in certain taxes to be presented on a net basis upon adoption of ASU 2014-09, thus reducing revenue in the income statement with no impact to net income or cash flows.  The Company does not expect the impact on reported revenue for the year ended December 31, 2018, or the quarters therein, to be material.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" (“ASU 2016-02”). ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets. Lessor accounting will remain similar to lessor accounting under previous GAAP, while aligning with the FASB’s new revenue recognition guidance. ASU 2016-02 is effective for the Company beginning January 1, 2019. Early adoption of ASU 2016-02 is permitted. The standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. While this ASU will have an impact on the Company's internal processes and controls and result in a change to the Company's accounting, the Company is still in the evaluation and information gathering stage of implementing the guidance and can not yet estimate the potential impact.

In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting", which amends the current stock compensation guidance. The amendments simplify the accounting for the taxes related to share-based payments, including adjustments to how excess tax benefits and a company’s payments for tax withholdings should be classified among other changes. The standard was effective for the Company on January 1, 2017.

The primary impact of adoption for the first nine months of 2017 was the recognition of $1.9 million of excess tax benefits in the provision for income taxes rather than paid-in-capital for the current period. Additional amendments to the accounting for income taxes and minimum statutory withholding tax requirements had no impact to retained earnings as of January 1, 2017, where the cumulative effect of these changes is required to be recorded. The Company elected to continue to estimate forfeitures expected to occur to determine the amount of compensation cost to be recognized in each period.

The Company elected to apply the presentation requirements for cash flows related to excess tax benefits prospectively as of January 1, 2017. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to any of the periods presented on the consolidated statement of cash flows, as such cash flows have historically been presented as a financing activity.

Dividend restrictions		The Senior Credit Agreement contains restrictions on certain payments, including dividends, when availability under the credit agreement is less than or equal to the greater of $100 million and 25% of the lesser of the revolving commitments and the borrowing base and our fixed charge coverage ratio is less than 1.0 to 1.0 (unless availability under the credit agreement is greater than $100 million and 40% of the lesser of the revolving commitments and the borrowing base). As of September 30, 2017, our ability to make restricted payments was not limited as our availability under the borrowing base was more than $100 million, while our fixed charge coverage ratio under our Senior Credit Agreement was less than 1.0 to 1.0. As of December 31, 2016, we had a shortfall of approximately $304.1 million of our net income and retained earnings subject to such restrictions before the fixed charge coverage ratio under our Senior Credit Agreement would exceed 1.0 to 1.0.
