NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1 — Description of Business and Basis of Presentation

Description of business — Murphy USA Inc. and its consolidated subsidiaries (“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, 2019, Murphy USA had a total of 1,479 Company stations of which 1,160 were Murphy USA and 319 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.

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, 2018, 2017 and 2016, 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 19, 2019.

Recently Issued Accounting Standards— 

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 by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under current GAAP. ASU 2016-02 requires that a lessee should recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. We adopted ASU 2016-02 as of January 1, 2019, using the modified retrospective approach. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification. We also elected the practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements. In addition, we elected the hindsight practical expedient to determine the lease term for existing leases. Our election of the hindsight practical expedient resulted in the shortening of lease terms for certain existing leases and the useful lives of corresponding leasehold improvements. In our application of hindsight, we evaluated the performance of the leased stores and the associated markets in relation to our overall real estate strategies, which resulted in the determination that renewal options would not be reasonably certain in determining the expected lease term. Adoption of the new standard resulted in the recording of additional net lease assets and lease liabilities of approximately $110.4 million and $110.7 million, respectively. The standard did not materially impact our consolidated net earnings and had no impact on cash flows. See Note 13 "Lease Accounting" for further details.

In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract". This ASU aligns the accounting treatment for capitalizing implementation costs incurred by customers in cloud computing arrangements in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This guidance is effective for the Company on January 1, 2020. Early adoption is permitted. The amendments in this update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently assessing the effect that this ASU will have on our financial position, results of operations, and disclosures but does not expect this update to have a material impact on the Company's consolidated financial statements.

Note 2 — Revenues

Revenue Recognition

Revenue is recognized when obligations under the terms of a contract with our customers are satisfied; generally, this occurs with the transfer of control of our petroleum products, convenience merchandise, Renewable Identification Numbers ("RINs") and other assets to our third-party customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Excise and sales tax that we collect where we have determined we are the principal in the transaction have been recorded as revenue on a jurisdiction-by-jurisdiction basis.

The Company enters into buy/sell and similar arrangements when petroleum products are held at one location but are needed at a different location. The Company often pays or receives funds related to the buy/sell arrangements based on location or quality differences. The Company continues to account for these transactions as non-monetary exchanges under existing accounting guidance and typically reports these on a net basis in the Consolidated Statements of Income.

The following tables disaggregates our revenue by major source for the three and nine months ended September 30, 2019 and 2018, respectively:

	Three Months Ended September 30, 2019						Three Months Ended September 30, 2018

² Primarily includes collection allowance on excise and sales taxes and other miscellaneous items

Marketing segment

Petroleum product sales (at retail). For our retail store locations, the revenue related to petroleum product sales is recognized as the fuel is pumped to our customers. The transaction price at the pump typically includes some portion of sales or excise taxes as levied in the respective jurisdictions. Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid. Our customers typically use a mixture of cash, checks, credit cards and debit cards to pay for our products as they are received. We have accounts receivable from the various credit/debit card providers at any point in time related to product sales made on credit cards and debit cards. These receivables are typically collected in two to seven days, depending on the terms with the particular credit/debit card providers. Payment fees retained by the credit/debit card providers are recorded as station and other operating expenses.

Petroleum product sales (at wholesale). Our sales of petroleum products at wholesale are generally recorded as revenue when the deliveries have occurred and legal ownership of the product has transferred to the customer. Title transfer for bulk refined product sales typically occurs at pipeline custody points and upon trucks loading at product terminals. For bulk pipeline sales, we record receivables from customers that are generally collected within a week from custody transfer date. For our rack product sales, the majority of our customers' accounts are drafted by us within 10 days from product transfer.

Merchandise sales. For our retail store locations, the revenue related to merchandise sales is recognized as the customer completes their purchase at our locations. The transaction price typically includes some portion of sales tax as levied in the respective jurisdictions. Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid. As noted above, a mixture of payment types are used for these revenues and the same terms for credit/debit card receivables are realized.

The most significant judgment with respect to merchandise sales revenue is determining whether we are the principal or agent for some categories of merchandise such as lottery tickets, lotto tickets, newspapers and other small categories of merchandise. For scratch-off lottery tickets, we have determined we are the principal in the majority of the jurisdictions and therefore we record those sales on a gross basis. We have some categories of merchandise (such as lotto tickets) where we are the agent and the revenues recorded for those transactions are our net commission only.

In June 2018, the Company initiated a loyalty pilot program through a limited number of its retail locations. The customers earn rewards based on their spending or other promotional activities. This program creates a performance obligation which requires us to defer a portion of sales revenue to the loyalty program participants until they redeem their rewards. The rewards may be redeemed for merchandise or cash discounts on fuel purchases. The program was rolled out chain-wide in March 2019. The deferred revenues recorded in the three and nine months ended September 30, 2019 were immaterial.

RINs sales. For the sale of RINs, we recognize revenue when the RIN is transferred to the counter-party and the sale is completed. Receivables from our counter-parties related to the RIN sales are typically collected within five days of the sale.

Other revenues. Items reported as other operating revenues include collection allowances for excise and sales tax and other miscellaneous items and are recognized as revenue when the transaction is completed.

Accounts receivable

Trade accounts receivable on the balance sheet represents both receivables related to contracts with customers and other trade receivables. At September 30, 2019 and December 31, 2018, we had $96.2 million and $79.4 million of receivables, respectively, related to contracts with customers recorded. All of the trade accounts receivable related to contracts with customers outstanding at the end of each period were collected during the succeeding quarter. These receivables were generally related to credit and debit card transactions along with short term bulk and wholesale sales to our customers, which have a very short settlement window.

Note 3 — Inventories

Inventories consisted of the following:

(Millions of dollars)	September 30, 2019			December 31, 2018
Finished products - First-In, First-Out ("FIFO") basis	$	276.6		$	219.4

Senior Notes

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 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 September 13, 2019, Murphy Oil USA, Inc., consummated a partial tender offer on its 6.00% $500 million Senior Notes due 2023 (the “2023 Senior Notes”). Following the completion of the tender offer, Murphy Oil USA, Inc. called the remaining 2023 Senior Notes and satisfied and discharged the indenture governing the 2023 Senior Notes. We paid a total of $514.5 million which included a call premium and all applicable accrued and unpaid interest. The call premium and unamortized debt discount and issuance costs were reported as Loss on early debt extinguishment in the consolidated income statements for the period ended September 30, 2019.

On September 13, 2019, Murphy Oil USA, Inc., issued $500 million of 4.75% Senior Notes due 2029 (the “2029 Senior Notes”). The net proceeds from the issuance of the 2029 Senior Notes were used to fund, in part, the tender offer and redemption of the 2023 Senior Notes. The 2029 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 2029 Senior Notes contains restrictive covenants that are essentially identical to the covenants for the 2027 Senior Notes.

The 2027 and 2029 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 2027 and 2029 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 August 2019, we amended and extended our existing credit agreement. The effective date of the agreement was extended to August, 2024.  The credit agreement provides for a committed $325 million asset-based loan (ABL) facility (with availability subject to the borrowing base described below) and a $200 million term loan facility with an additional $50 million available until December 31, 2019.  It also provides for a $150 million uncommitted incremental facility. On August 27, 2019, Murphy Oil USA, Inc. borrowed $200 million under the term loan facility that has a four-year term with a current outstanding principal of $200 million and prepaid the remaining balance of the prior term loan of $57 million. As of September 30, 2019, 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 midstream 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 $100 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 greater of the federal funds effective rate and the overnight bank funding rate determined by the Federal Reserve Bank of New York 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 a 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.

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 million (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, 2019, our fixed charge coverage ratio was 1.1. Our secured debt to EBITDA ratio as of September 30, 2019 was 0.43 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 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, 2019 and December 31, 2018, our ability to make restricted payments was not limited as our fixed charge coverage ratio was greater than 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. 

Note 5 — Asset Retirement Obligations (ARO)

The majority of the ARO recognized by the Company at September 30, 2019 and December 31, 2018 is 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.

(Millions of dollars)	September 30, 2019			December 31, 2018
Balance at beginning of period	$	30.7		$	28.2
Accretion expense	1.6			2.0
Settlements of liabilities	(0.2		)	(0.3		)
Liabilities incurred	0.2			0.8
Balance at end of period	$	32.3		$	30.7

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.

Note 6 — Income Taxes

The effective tax rate is calculated as the amount of income tax expense (benefit) divided by income before income tax expense (benefit). For the three and nine month periods ended September 30, 2019 and 2018, the Company’s approximate effective tax rates were as follows:

	2019	2018
Three months ended September 30,	24.2%	21.1%
Nine months ended September 30,	23.7%	21.5%

In the nine months ended September 30, 2019, the Company recognized approximately $0.9 million of excess tax benefits related to stock compensation for employees. For the nine months ended September 30, 2018, the Company recognized a tax benefit of approximately $2.8 million of excess tax benefits related to stock compensation and a tax benefit of approximately $2.7 million related to the settlement of prior year state uncertain tax positions.

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, 2019, the earliest year

remaining open for federal examination is 2016 and for certain states it ranges from 2013-2017.  In addition to the pre-separation state returns being open under statute, certain 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.

Note 7 — 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 $5.0 million.

On February 6, 2019, the Committee granted nonqualified stock options for 99,400 shares at an exercise price of $76.15 per share under the terms of the MUSA 2013 Plan.  The Black-Scholes valuation for these awards is $20.48 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 26,550 time-based restricted units granted at a grant date fair value of $76.15 along with 53,100 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 $100.65 per unit.  For the ROACE portion of the awards, the valuation will be based on the grant date fair value of $76.15 per unit and the number of awards will be periodically assessed to determine the probability of vesting. 

On March 26, 2019, the Committee also granted 46,725 time-based restricted stock units granted to certain employees with a grant date fair value of $82.84 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 2019, the Company issued 13,086 restricted stock units to its non-employee directors at a grant date fair value of $76.63 per share.  These shares vest in three years from the grant date. 

For the nine months ended September 30, 2019 and 2018, share-based compensation was $8.0 million and $6.8 million, respectively.  The income tax benefit realized for the tax deductions from options exercised for the nine months ended September 30, 2019 and 2018 was $0.1 million and $2.1 million, respectively.

Note 8— 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 credit worthy major financial institutions or over national exchanges such as the New York Mercantile Exchange (“NYMEX”). As of September 30, 2019, all current derivative activity is immaterial.

At September 30, 2019 and December 31, 2018, cash deposits of $1.0 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, 2019 or December 31, 2018, respectively.

Note 9 – 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 July 24, 2019, the Board of Directors approved an up to $400 million share repurchase program to be executed over the two-year period ending July 2021. Purchases may be effected in the open market, through privately negotiated transactions, through one or more accelerated stock repurchase programs, through a combination of the foregoing or in any other manner in the discretion of management. Purchases will be made subject to available cash, market conditions and compliance with our financing arrangements at any time during the period of authorization. We may use cash from operations as well as draws under our credit facilities to effect purchases.

Prior to the July authorization, the Company had continued to conduct share repurchases under quarterly allocations in line with its past practice, subject to market conditions and cash availability. For the nine months ended September 30, 2019, the Company acquired 1,597,731 shares of common stock for an average price of $87.09 per share including brokerage fees and for the nine months ended September 30, 2018, 1,994,632 shares were repurchased for an average price of $72.39 per share.

The following table provides a reconciliation of basic and diluted earnings per share computations for the three and nine months ended September 30, 2019 and 2018:

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

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.

Note 10 — Other Financial Information

CASH FLOW DISCLOSURES — Cash income taxes paid (collected), net of refunds, were $16.2 million and $12.0 million for the nine month periods ended September 30, 2019 and 2018, respectively. Interest paid, net of amounts capitalized, was $46.0 million and $41.0 million for the nine month periods ended September 30, 2019 and 2018, respectively.

Note 11 — 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, 2019 and December 31, 2018. 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, Restricted cash, and Trade accounts payable and accrued liabilities, all of which had fair values approximating carrying amounts. The fair value of Current and Long-term debt was estimated based on rates offered to the Company at that time for debt of the same maturities. The Company has off-balance sheet exposures relating to certain financial guarantees and letters of credit. The fair value of these, which represents fees associated with obtaining the instruments, was nominal.

Note 12 — 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, 2019, 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, 2019. 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 self-insured retention of $3.0 million per occurrence, and auto liability insurance with a deductible of $0.3 million per occurrence. As of September 30, 2019, 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 $21.3 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, 2019, the Company had contingent liabilities of $17.0 million on outstanding letters of credit. The Company has not accrued a liability in its balance sheet related to these financial guarantees and letters of credit because it is believed that the likelihood of having these drawn is remote.

Note 13 — Lease Accounting

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

As the implicit interest rate is not readily determinable in most of the Company's lease agreements, the Company uses its estimated secured incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.

Lessor — We have various arrangements for certain spaces for food service and vending equipment under which we are the lessor. These leases meet the criteria for operating lease classification. Lease income associated with these leases is immaterial.

Lessee —We lease land for 216 stations, one terminal, a hangar and various equipment. Our lease agreements do not contain any material residual value guarantees and approximately 102 sites leased from Walmart contain restrictive covenants, though the restrictions are deemed to have an immaterial impact.

Leases are reflected in the following balance sheet accounts:

Note 14 — Business Segment

The Company's operations have one reportable 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. Net settlement proceeds from litigation are included in Corporate and other assets operating income. The reportable segment was determined based on information reviewed by the Chief Operating Decision Maker (CODM).

For purposes of this Management’s Discussion and Analysis, references to “Murphy USA”, the “Company”, “we”, “us” and “our” refer to Murphy USA Inc. and its subsidiaries on a consolidated basis.  

Management’s Discussion and Analysis is organized as follows:

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, 2019, we had a total of 1,479 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 Corporation 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. 

33

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 over time 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 price 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.  Crude oil prices in 2019 have fluctuated widely during the first nine months of 2019 and the price per barrel has ranged from a low in January of approximately $47 to a high in April of approximately $66, and ended September at approximately $54. Total fuel contribution (retail fuel margin plus product supply and wholesale ("PS&W") results including Renewable Identification Numbers ("RINs") for the third quarter of 2019 was 20.1 cents per gallon, a 24.1% increase when compared to the 2018 third quarter total fuel contribution of 16.2 cents per gallon.

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 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 impact the net benefit we receive from RINs on a company-wide basis either favorably or unfavorably. Revenue from the sales of RINs is included in “Other operating revenues” in the Consolidated Statements of Income. The Renewable Fuel Standard ("RFS") program continues to be unpredictable and ethanol RIN prices have ranged from $0.14 to $0.25 during Q3 2019, which compares to $0.11 to $0.27 in Q3 2018. The average RIN price received in Q3 of both 2019 and 2018 was $0.20.

As of September 30, 2019, we have $800 million of Senior Notes and $200 million of a 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, 2019, we have additional available capacity under the committed $325 million credit facilities (subject to the borrowing base), together with capacity under a $150 million incremental uncommitted facility. 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. For additional information see Significant Sources of Capital in the Capital Resources and Liquidity section.

The Company currently anticipates total capital expenditures (including land for future developments) for the full year 2019 to range from approximately $225 million to $275 million depending on how many new sites are completed.  We intend to fund the remainder of our capital program in 2019 primarily using operating cash flow but will supplement funding where necessary using borrowings available under 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 between 21% and 25% for the remainder of the year.

34

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, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

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 19 “Business Segments” in the audited combined financial statements for the year ended December 31, 2018 included with our Annual Report on Form 10-K and Note 14 “Business Segment” in the accompanying unaudited consolidated financial statements for the three and nine months ended September 30, 2019.

Results of Operations

Consolidated Results

For the three month period ended September 30, 2019, the Company reported net income of $69.2 million, or $2.18 per diluted share, on revenue of $3.7 billion. Net income was $45.0 million for the same period in 2018, or $1.38 per diluted share, on $3.8 billion in revenue.  The increase in net income is primarily due to higher all-in fuel margins combined with increased merchandise margins, partially offset by higher station operating expenses, loss on early debt extinguishment, and increased income tax expense.

For the nine month period ended September 30, 2019, the Company reported net income of $107.2 million, or $3.33 per diluted share, on revenue of $10.6 billion. Net income was $136.1 million for the same period in 2018, or $4.11 per diluted share, on $10.9 billion in revenue.  The decrease in net income for the nine month period is primarily due to the receipt in 2018 of approximately $37.8 million (after tax) from the settlement of damages incurred in connection with the 2010 Deepwater Horizon oil spill, combined with higher station operating expenses, increased depreciation expense, and the loss on early debt extinguishment, which was partially offset by improved total fuel contribution and merchandise margins.

Three Months Ended September 30, 2019 versus Three Months Ended September 30, 2018

Quarterly revenues for 2019 decreased $130.4 million, or 3.4%, compared to the same quarter in 2018.  The lower revenues were related to lower average retail and wholesale fuel prices and lower PS&W revenues including RINs, partially offset by increased merchandise sales revenues, higher retail fuel sales volumes, and increased store count in 2019.

Total cost of sales decreased $191.0 million, or 5.4%, compared to 2018.  In the current-year quarter, the lower costs were primarily due to lower fuel purchase costs which were driven by lower wholesale prices, partially offset by higher fuel volumes purchased and higher merchandise costs.

Station and other operating expenses increased $3.7 million, or 2.6%, from 2018.  Increased store count along with higher employee related benefits contributed to the increase in the current quarter.

Selling, general and administrative ("SG&A") expenses for 2019 increased $3.4 million, or 10.4%, from 2018. The increase in SG&A costs is primarily due to higher professional fees and incentive award expense.

Depreciation and amortization expense increased $3.4 million, or 9.9%, due primarily to an increase in store counts from the third quarter of 2018.   

The effective income tax rate was approximately 24.2% for the third quarter of 2019 versus 21.1% for the same period of 2018. The effective income tax rate in the prior year was lower due to the excess tax benefits related to share-based payments in the third quarter of 2018.

35

Nine Months Ended September 30, 2019 versus Nine Months Ended September 30, 2018

Year-to-date revenues for 2019 decreased $286.8 million, or 2.6%, compared to the same period in 2018.  The lower revenues were related to lower average retail and wholesale fuel prices and lower PS&W revenues including RINs, partially offset by increased merchandise sales revenues, higher retail fuel sales volumes, and increased store count in 2019.

Total cost of sales decreased $357.4 million, or 3.5%, compared to 2018.  In the current year, the lower costs were primarily due to lower fuel purchase costs which were driven by lower wholesale prices, partially offset by higher fuel volumes and increased merchandise cost of goods sold.

Station and other operating expenses increased $19.9 million, or 5.0%, from 2018.  Increased store count along with higher employee related benefits, planned and unplanned maintenance activity, and other store-level costs contributed to the increase in the current year.

SG&A expenses for 2019 increased year-over-year by 3.3%, or $3.4 million, from 2018, due primarily to professional fees.

Net settlement proceeds for the first nine months of 2019 were $50.3 million (before tax) lower than in the same period of 2018.

Depreciation and amortization expense increased $14.8 million, or 14.9%, due primarily to an increase in store count from the same period last year.   

The effective income tax rate was approximately 23.7% for 2019 versus 21.5% for the same period of 2018. The lower effective income tax rate in 2018 was primarily due to the higher amount of excess tax benefits related to share-based payments in 2018 and the effects of the settlement of state uncertain tax positions in Q1 2018.

Same store sales (SSS) metric 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 be excluded from the calculation during the period it is out of service. Newly constructed sites do not enter the calculation until they are open for each full calendar year for the periods being compared (open by January 1, 2018 for the sites being compared in the 2019 versus 2018 comparison). When prior period same store sales volumes or sales are presented, they have not been revised for current year activity for raze-and-rebuilds and asset dispositions.

Three Months Ended September 30, 2019 versus Three Months Ended September 30, 2018 

Net income in the Marketing segment for 2019 increased $39.4 million compared to the 2018 period. The primary drivers were the 24.1% increase on a cpg basis in total fuel contribution to 20.1 cpg in 2019 and higher total merchandise contribution which increased 6.4% to $111.2 million, which were partially offset by a higher station operating expenses.

Total revenues for the Marketing segment were approximately $3.7 billion in 2019 compared to $3.8 billion in 2018. The primary cause of the lower revenues was a $0.23 per gallon decrease in the average retail fuel price in the 2019 third quarter and lower RIN revenues, which were offset by a 9.2% increase in merchandise sales and higher fuel volumes.  Revenues included excise taxes collected and remitted to government authorities of $498.9 million in 2019 and $464.1 million in 2018.  

Total fuel sales volumes on a same store sales ("SSS") basis increased 2.7% to 249.5 thousand gallons per store in the 2019 period.  Retail fuel margin dollars increased 36.3% in the 2019 quarter on higher volumes and margin rate of 18.4 cpg for the third quarter of 2019 which compared to 14.2 cpg in the same quarter of 2018. 

Total PS&W margin dollars, excluding RINs, were $10.7 million in the 2019 period compared to $9.7 million in 2018. The increase in the current period was due to improvements and optimization activities across our supply and distribution network.

The 2019 quarter includes the sale of RINs of $8.5 million compared to $11.6 million in 2018, which consisted of sales of 42 million RINs at an average selling price of $0.20 per RIN while the prior-year quarter had sales of 57 million RINs at an average price of $0.20 per RIN.

39

Total merchandise sales increased 9.2% to $681.1 million in 2019's third quarter from $623.7 million in 2018 and was primarily due to an increase in tobacco products sales of 8.7% and in non-tobacco sales of 3.3%, on an SSS basis. Quarterly total merchandise contribution in 2019 was 6.4% higher than 2018.  The increase in gross margin dollars in the current period was due primarily to higher sales across the chain and strong new store performance. Increased contribution from lower-margin tobacco categories and enhanced promotional activities lowered the average unit margins to 16.3% in the current-year quarter. Total merchandise contribution dollars per store grew 6.0% to $25.7 thousand on a SSS basis from growth in the tobacco category.

Station and other operating expenses increased $3.7 million in the current period compared to 2018 levels. On an APSM basis, expenses applicable to retail excluding payment fees increased 1.7%, primarily due to higher employee related costs.

Depreciation expense increased $2.7 million in the 2019 period, an increase of 8.6% over the prior period. This increase was primarily caused by more stores operating in the 2019 period compared to the prior-year period.

Nine Months Ended September 30, 2019 versus Nine Months Ended September 30, 2018 

Net income in the Marketing segment for 2019 increased $28.6 million compared to the 2018 period. The primary drivers were the 6.0% increase in total fuel contribution to 15.8 cpg in 2019 from 14.9 cpg in 2018, an increase of 5.3% in merchandise gross margin to $314.2 million, which were partially offset by higher station operating expenses and depreciation expense.

Total revenues for the Marketing segment were approximately $10.6 billion for 2019 compared to $10.9 billion for 2018. The primary cause of the decrease in revenues was a $0.18 per gallon decrease in the average retail fuel price in the 2019 period and lower RIN revenues. This decrease was partially offset by a 7.7% increase in merchandise sales and increased fuel volumes. Revenues included excise taxes collected and remitted to government authorities of $1.5 billion in 2019 and $1.4 billion in 2018.  

Retail fuel margin dollars increased 18.9% in the 2019 period on higher volumes, and the margin rate was 13.5 cpg in 2019, a 13.4% increase from the prior year. Total fuel sales volumes increased 5.1% in the 2019 period.

Total PS&W margin dollars, excluding RINs, were $46.6 million in the 2019 period compared to $24.7 million in 2018. The improvement in the current period was primarily due to our ongoing optimization activities within our supply and distribution network that enabled us to reduce the total laid-in costs at our retail sites.

The 2019 period includes the sale of RINs of $28.6 million compared to $67.3 million in 2018, which consisted of sales of 157 million RINs at an average selling price of $0.18 per RIN in the current year compared to 2018 sales of 177 million RINs at an average price of $0.38 per RIN.

Total merchandise sales increased 7.7% to $1.9 billion in the first nine months of 2019 from $1.8 billion in 2018 and was primarily due to an increase in tobacco products sales of 7.1% and non-tobacco sales of 4.0% on an SSS basis. Total merchandise contribution in 2019 was 5.3% higher than 2018.  The increase in gross margin dollars in the current period was due primarily to higher sales across the chain and strong new store performance. While unit margins were slightly lower than the prior year at 16.1%, total merchandise contribution dollars grew 5.3% on a SSS basis through successful execution of store level initiatives and enhanced promotional activities, which helped to improve both tobacco and non-tobacco categories.

Station and other operating expenses increased $19.9 million in the current period compared to 2018 levels. On an APSM basis, expenses applicable to retail excluding payment fees increased 4.3%, primarily due to higher employee related costs, planned and unplanned maintenance activity and other store-level costs.

Depreciation expense increased $11.6 million in the 2019 period, an increase of 12.6% over the prior period. This increase was primarily caused by more stores operating in the 2019 period compared to the prior-year period.

Corporate and Other Assets

Three Months Ended September 30, 2019 versus Three Months Ended September 30, 2018

After-tax results for Corporate and other assets for the third quarter were a loss of $24.8 million compared to a loss of $9.6 million in the third quarter of 2018. The difference is primarily due to the loss on early debt extinguishment, additional interest expense due to the early extinguishment of the 2023 Notes and higher depreciation expense during the current-year quarter.

Nine Months Ended September 30, 2019 versus Nine Months Ended September 30, 2018

After-tax results for Corporate and other assets for the first nine months were a loss of $47.5 million compared to a profit of $10.0 million in the same period of 2018. The difference is primarily due to the prior-year nine months including proceeds of $37.8 million (after tax) from the settlement of damages incurred in connection with the 2010 Deepwater Horizon oil spill combined with the loss on early debt extinguishment of $14.8 million recorded in the third quarter of 2019.

Non-GAAP Measures

The following table sets forth the Company’s Adjusted EBITDA for the three and nine months ended September 30, 2019 and 2018.  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, net settlement proceeds, (gain) loss on sale of assets, loss on early debt extinguishment and other non-operating (income) expense).  EBITDA and Adjusted EBITDA are not measures that are prepared in accordance with U.S. generally accepted accounting principles (GAAP).

We use Adjusted EBITDA in our operational and financial decision-making, believing that the measure is useful to eliminate certain items in order to focus on what we deem to be 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 EBITDA and Adjusted EBITDA may be prepared differently by us than by other companies using similarly titled non-GAAP measures.

Capital Resources and Liquidity

Significant Sources of Capital

We have a committed $325 million asset based loan facility (the “ABL facility”), which is subject to the remaining borrowing capacity of $258 million at September 30, 2019 (which can be utilized for working capital and other general corporate purposes, including supporting our operating model as described herein) and a $250 million term loan facility, as well as a $150 million incremental uncommitted facility. As of September 30, 2019, we had $200 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.

Our term loan matures in August 2023 and our $325 million asset-backed lending facility, which has not been drawn against to-date, matures in August 2024. The remainder of the term facility, $50 million, may be incurred to fund working capital and other general corporate purposes and may be drawn in no more than two borrowings occurring on or prior to December 31, 2019.

Operating Activities

Net cash provided by operating activities was $251.6 million for the nine months ended September 30, 2019 and was $241.4 million for the comparable period in 2018. Net income decreased $28.9 million in 2019 compared to the corresponding period in 2018 and was offset in part by the adjustment for loss on early debt extinguishment of $14.8 million, additional depreciation and amortization expense of $14.8 million, and changes in working capital $12.1 million.

Investing Activities

For the nine months ended September 30, 2019, cash required by investing activities was $152.0 million compared to $167.7 million in 2018. The lower investing cash use in the current period was primarily due to timing of capital expenditures in the current year. Other investing activities provided $1.7 million in cash during 2019 compared to cash required of $4.7 million in 2018.

42

Financing Activities

Financing activities in the nine months ended September 30, 2019 required cash of $36.4 million compared to $168.3 million of cash required in the nine months ended September 30, 2018. The current period included $139.1 million for the repurchase of common shares, which was a decrease of $5.3 million from the prior-year period. Amounts related to share-based compensation required $3.6 million less in cash during 2019 than in 2018. Net borrowings of debt provided $120.6 million compared to 2018 which had net repayments of debt requiring $15.9 million. In 2019, early debt extinguishment costs required the use of $10.4 million and debt issuance costs were $3.1 million compared to no such costs in 2018.

Share Repurchase Program

On July 24, 2019, the Board of Directors approved an up to $400 million share repurchase program to be executed over the two-year period ending July 2021. Purchases may be effected in the open market, through privately negotiated transactions, through one or more accelerated stock repurchase programs, through a combination of the foregoing or in any other manner in the discretion of management. Purchases will be made subject to available cash, market conditions and compliance with our financing arrangements at any time during the period of authorization. We may use cash from operations as well as draws under our credit facilities to effect purchases.

Prior to the July authorization, the Company had continued to conduct share repurchases under quarterly allocations in line with our past practice. During the first nine months of 2019, a total of 1,597,731 shares were repurchased for $139.1 million, of which 1,093,334 shares for $98.4 million were made under the new plan.

On September 13, 2019, Murphy Oil USA, Inc., consummated a partial tender offer on its 6.00% $500 million Senior Notes due 2023 (the “2023 Senior Notes”). Following the completion of the tender offer, Murphy Oil USA, Inc. called the remaining 2023 Senior Notes and satisfied and discharged the indenture governing the 2023 Senior Notes. We paid a total of $514.5 million which included a call premium and all applicable accrued and unpaid interest. The call premium and unamortized debt discount and issuance costs were reported as Loss on early debt extinguishment in the consolidated income statements for the period ended September 30, 2019.

On September 13, 2019, Murphy Oil USA, Inc., issued $500 million of 4.75% Senior Notes due 2029 (the “2029 Senior Notes”). The net proceeds from the issuance of the 2029 Senior Notes were used to fund, in part, the tender offer and redemption of the 2023 Senior Notes. The 2029 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 2029 Senior Notes contains restrictive covenants that are essentially identical to the covenants for the 2027 Senior Notes.

The 2027 and 2029 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 2027 and 2029 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 August 2019, we amended and extended our existing credit agreement. The effective date of the agreement was extended to August, 2024.  The credit agreement provides for a committed $325 million asset-based loan (ABL) facility (with availability subject to the borrowing base described below) and a $200 million term loan facility with an additional $50 million available until December 31, 2019.  It also provides for a $150 million uncommitted incremental facility. On August 27, 2019, Murphy Oil USA, Inc. borrowed $200 million under the term loan facility that has a four-year term with a current outstanding principal of $200 million in connection we prepaid the previous term loan balance of $57 million. As of September 30, 2019, 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 midstream 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 $100 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 greater of the federal funds effective rate and the overnight bank funding rate determined by the Federal Reserve Bank of New York 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

44

0.50% to 1.00% per annum depending on a 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.

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 million (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, 2019, our fixed charge coverage ratio was 1.1. Our secured debt to EBITDA ratio as of September 30, 2019 was 0.43 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 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, 2019 and December 31, 2018, our ability to make restricted payments was not limited as our fixed charge coverage ratio was greater than 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 nine month periods ended September 30, 2019 and 2018:

	Three Months Ended September 30,				Nine Months Ended September 30,
(Millions of dollars)	2019		2018		2019		2018
Marketing:
Company stores	$	44.8	$	49.7	$	104.4	$	110.4
Terminals	2.2		0.3		2.7		0.4
Sustaining capital	5.4		9.4		12.2		26.4
Corporate and other assets	16.4		2.5		39.2		15.3
Total	$	68.8	$	61.9	$	158.5	$	152.5

We currently expect capital expenditures for the full year 2019 to range from approximately $225 million to $275 million, including $140 million for retail growth, approximately $30 million for maintenance capital, with the remaining funds earmarked for other corporate investments, including EMV compliance and other strategic initiatives. See Note 16 “Commitments” in the audited consolidated financial statements for the year ended December 31, 2018 included in our Annual Report on Form 10-K for more information.

Critical Accounting Policies

There has been no material update to our critical accounting policies since our Annual Report on Form 10-K for the year ended December 31, 2018.  For more information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Critical Accounting Policies” in the Form 10-K.

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains certain statements or may suggest “forward-looking” information (as defined in the Private Securities Litigation Reform Act of 1995) that involve risk and uncertainties, including, but not limited to anticipated store openings, fuel margins, merchandise margins, sales of RINs and trends in our operations. Such statements are based upon the current beliefs and expectations of the Company’s management and are subject to significant risks and uncertainties. Actual future results may differ materially from historical results or current expectations depending upon factors including, but not limited to: our ability to continue to maintain a good business relationship with Walmart; successful execution of our growth strategy, including our ability to realize the anticipated benefits from such growth initiatives, and the timely completion of construction associated with our newly planned stores which may be impacted by the financial health of third parties; our ability to effectively manage our inventory, disruptions in our supply chain and our ability to control costs; the impact of severe weather events, such as hurricanes, floods and earthquakes; the impact of any systems failures, cybersecurity and/or security breaches, including any security breach that results in theft, transfer or unauthorized disclosure of customer, employee or company information or our compliance with information security and privacy laws and regulations in the event of such an incident; successful execution of our information technology strategy; future tobacco or e-cigarette legislation and any other efforts that make purchasing tobacco products more costly or difficult could hurt our revenues and impact gross margins; efficient and proper allocation of our capital resources; compliance with debt covenants; availability and cost of credit; and changes in interest rates. Our public filings, including our Annual Report on our Form 10-K for the year ended December 31, 2018 contains other information on these and other factors that could affect our financial results and cause actual results to differ materially from any forward-looking information we may provide. The Company undertakes no obligation to update or revise any forward-looking statements to reflect subsequent events, new information or future circumstances.

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 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 Note 8 “Financial Instruments and Risk Management” in the accompanying unaudited consolidated financial statements, there were short-term commodity derivative contracts in place at September 30, 2019 to 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 have been 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 Note 12 “Financial Instruments and Risk Management” in our audited combined financial statements for the year ended December 31, 2018 included in the Form 10-K and Note 8 “Financial Instruments and Risk Management” in the accompanying unaudited consolidated financial statements for the nine months ended September 30, 2019.

ITEM 1A. RISK FACTORS

Our business, results of operations, cash flows and financial condition involve various risks and uncertainties.

Fair Value Disclosures [Abstract]

Schedule of Carrying Amounts and Estimated Fair Value of Financial Instruments

The following table presents the carrying amounts and estimated fair values of financial instruments held by the Company at September 30, 2019 and December 31, 2018. 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, Restricted cash, and Trade accounts payable and accrued liabilities, all of which had fair values approximating carrying amounts. The fair value of Current and Long-term debt was estimated based on rates offered to the Company at that time for debt of the same maturities. The Company has off-balance sheet exposures relating to certain financial guarantees and letters of credit. The fair value of these, which represents fees associated with obtaining the instruments, was nominal.

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 $5.0 million.

On February 6, 2019, the Committee granted nonqualified stock options for 99,400 shares at an exercise price of $76.15 per share under the terms of the MUSA 2013 Plan.  The Black-Scholes valuation for these awards is $20.48 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 26,550 time-based restricted units granted at a grant date fair value of $76.15 along with 53,100 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 $100.65 per unit.  For the ROACE portion of the awards, the valuation will be based on the grant date fair value of $76.15 per unit and the number of awards will be periodically assessed to determine the probability of vesting. 

On March 26, 2019, the Committee also granted 46,725 time-based restricted stock units granted to certain employees with a grant date fair value of $82.84 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 2019, the Company issued 13,086 restricted stock units to its non-employee directors at a grant date fair value of $76.63 per share.  These shares vest in three years from the grant date. 

For the nine months ended September 30, 2019 and 2018, share-based compensation was $8.0 million and $6.8 million, respectively.  The income tax benefit realized for the tax deductions from options exercised for the nine months ended September 30, 2019 and 2018 was $0.1 million and $2.1 million, respectively.

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, 2019 and December 31, 2018. 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, Restricted cash, and Trade accounts payable and accrued liabilities, all of which had fair values approximating carrying amounts. The fair value of Current and Long-term debt was estimated based on rates offered to the Company at that time for debt of the same maturities. The Company has off-balance sheet exposures relating to certain financial guarantees and letters of credit.

Revenue from Contract with Customer [Abstract]

Revenues

Revenue Recognition

Revenue is recognized when obligations under the terms of a contract with our customers are satisfied; generally, this occurs with the transfer of control of our petroleum products, convenience merchandise, Renewable Identification Numbers ("RINs") and other assets to our third-party customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Excise and sales tax that we collect where we have determined we are the principal in the transaction have been recorded as revenue on a jurisdiction-by-jurisdiction basis.

The Company enters into buy/sell and similar arrangements when petroleum products are held at one location but are needed at a different location. The Company often pays or receives funds related to the buy/sell arrangements based on location or quality differences. The Company continues to account for these transactions as non-monetary exchanges under existing accounting guidance and typically reports these on a net basis in the Consolidated Statements of Income.

The following tables disaggregates our revenue by major source for the three and nine months ended September 30, 2019 and 2018, respectively:

	Three Months Ended September 30, 2019						Three Months Ended September 30, 2018

² Primarily includes collection allowance on excise and sales taxes and other miscellaneous items

Marketing segment

Petroleum product sales (at retail). For our retail store locations, the revenue related to petroleum product sales is recognized as the fuel is pumped to our customers. The transaction price at the pump typically includes some portion of sales or excise taxes as levied in the respective jurisdictions. Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid. Our customers typically use a mixture of cash, checks, credit cards and debit cards to pay for our products as they are received. We have accounts receivable from the various credit/debit card providers at any point in time related to product sales made on credit cards and debit cards. These receivables are typically collected in two to seven days, depending on the terms with the particular credit/debit card providers. Payment fees retained by the credit/debit card providers are recorded as station and other operating expenses.

Petroleum product sales (at wholesale). Our sales of petroleum products at wholesale are generally recorded as revenue when the deliveries have occurred and legal ownership of the product has transferred to the customer. Title transfer for bulk refined product sales typically occurs at pipeline custody points and upon trucks loading at product terminals. For bulk pipeline sales, we record receivables from customers that are generally collected within a week from custody transfer date. For our rack product sales, the majority of our customers' accounts are drafted by us within 10 days from product transfer.

Merchandise sales. For our retail store locations, the revenue related to merchandise sales is recognized as the customer completes their purchase at our locations. The transaction price typically includes some portion of sales tax as levied in the respective jurisdictions. Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid. As noted above, a mixture of payment types are used for these revenues and the same terms for credit/debit card receivables are realized.

The most significant judgment with respect to merchandise sales revenue is determining whether we are the principal or agent for some categories of merchandise such as lottery tickets, lotto tickets, newspapers and other small categories of merchandise. For scratch-off lottery tickets, we have determined we are the principal in the majority of the jurisdictions and therefore we record those sales on a gross basis. We have some categories of merchandise (such as lotto tickets) where we are the agent and the revenues recorded for those transactions are our net commission only.

In June 2018, the Company initiated a loyalty pilot program through a limited number of its retail locations. The customers earn rewards based on their spending or other promotional activities. This program creates a performance obligation which requires us to defer a portion of sales revenue to the loyalty program participants until they redeem their rewards. The rewards may be redeemed for merchandise or cash discounts on fuel purchases. The program was rolled out chain-wide in March 2019. The deferred revenues recorded in the three and nine months ended September 30, 2019 were immaterial.

RINs sales. For the sale of RINs, we recognize revenue when the RIN is transferred to the counter-party and the sale is completed. Receivables from our counter-parties related to the RIN sales are typically collected within five days of the sale.

Other revenues. Items reported as other operating revenues include collection allowances for excise and sales tax and other miscellaneous items and are recognized as revenue when the transaction is completed.

Accounts receivable

Trade accounts receivable on the balance sheet represents both receivables related to contracts with customers and other trade receivables. At September 30, 2019 and December 31, 2018, we had $96.2 million and $79.4 million of receivables, respectively, related to contracts with customers recorded. All of the trade accounts receivable related to contracts with customers outstanding at the end of each period were collected during the succeeding quarter. These receivables were generally related to credit and debit card transactions along with short term bulk and wholesale sales to our customers, which have a very short settlement window.

Income Taxes

Income Taxes

The effective tax rate is calculated as the amount of income tax expense (benefit) divided by income before income tax expense (benefit). For the three and nine month periods ended September 30, 2019 and 2018, the Company’s approximate effective tax rates were as follows:

	2019	2018
Three months ended September 30,	24.2%	21.1%
Nine months ended September 30,	23.7%	21.5%

In the nine months ended September 30, 2019, the Company recognized approximately $0.9 million of excess tax benefits related to stock compensation for employees. For the nine months ended September 30, 2018, the Company recognized a tax benefit of approximately $2.8 million of excess tax benefits related to stock compensation and a tax benefit of approximately $2.7 million related to the settlement of prior year state uncertain tax positions.

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, 2019, the earliest year

remaining open for federal examination is 2016 and for certain states it ranges from 2013-2017.  In addition to the pre-separation state returns being open under statute, certain 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.

Segment Reporting [Abstract]

Business Segment

Business Segment

The Company's operations have one reportable 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. Net settlement proceeds from litigation are included in Corporate and other assets operating income. The reportable segment was determined based on information reviewed by the Chief Operating Decision Maker (CODM).

Senior Notes

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 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 September 13, 2019, Murphy Oil USA, Inc., consummated a partial tender offer on its 6.00% $500 million Senior Notes due 2023 (the “2023 Senior Notes”). Following the completion of the tender offer, Murphy Oil USA, Inc. called the remaining 2023 Senior Notes and satisfied and discharged the indenture governing the 2023 Senior Notes. We paid a total of $514.5 million which included a call premium and all applicable accrued and unpaid interest. The call premium and unamortized debt discount and issuance costs were reported as Loss on early debt extinguishment in the consolidated income statements for the period ended September 30, 2019.

On September 13, 2019, Murphy Oil USA, Inc., issued $500 million of 4.75% Senior Notes due 2029 (the “2029 Senior Notes”). The net proceeds from the issuance of the 2029 Senior Notes were used to fund, in part, the tender offer and redemption of the 2023 Senior Notes. The 2029 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 2029 Senior Notes contains restrictive covenants that are essentially identical to the covenants for the 2027 Senior Notes.

The 2027 and 2029 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 2027 and 2029 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 August 2019, we amended and extended our existing credit agreement. The effective date of the agreement was extended to August, 2024.  The credit agreement provides for a committed $325 million asset-based loan (ABL) facility (with availability subject to the borrowing base described below) and a $200 million term loan facility with an additional $50 million available until December 31, 2019.  It also provides for a $150 million uncommitted incremental facility. On August 27, 2019, Murphy Oil USA, Inc. borrowed $200 million under the term loan facility that has a four-year term with a current outstanding principal of $200 million and prepaid the remaining balance of the prior term loan of $57 million. As of September 30, 2019, 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 midstream 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 $100 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 greater of the federal funds effective rate and the overnight bank funding rate determined by the Federal Reserve Bank of New York 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 a 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.

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 million (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, 2019, our fixed charge coverage ratio was 1.1. Our secured debt to EBITDA ratio as of September 30, 2019 was 0.43 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 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, 2019 and December 31, 2018, our ability to make restricted payments was not limited as our fixed charge coverage ratio was greater than 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.

Financial Instruments and Risk Management

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 credit worthy major financial institutions or over national exchanges such as the New York Mercantile Exchange (“NYMEX”). As of September 30, 2019, all current derivative activity is immaterial.

At September 30, 2019 and December 31, 2018, cash deposits of $1.0 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, 2019 or December 31, 2018, respectively.

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, 2019, 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, 2019. 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 self-insured retention of $3.0 million per occurrence, and auto liability insurance with a deductible of $0.3 million per occurrence. As of September 30, 2019, 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 $21.3 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, 2019, the Company had contingent liabilities of $17.0 million on outstanding letters of credit. The Company has not accrued a liability in its balance sheet related to these financial guarantees and letters of credit because it is believed that the likelihood of having these drawn is remote.

Description of Business and Basis of Presentation (Policies)

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 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 by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under current GAAP. ASU 2016-02 requires that a lessee should recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. We adopted ASU 2016-02 as of January 1, 2019, using the modified retrospective approach. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification. We also elected the practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements. In addition, we elected the hindsight practical expedient to determine the lease term for existing leases. Our election of the hindsight practical expedient resulted in the shortening of lease terms for certain existing leases and the useful lives of corresponding leasehold improvements. In our application of hindsight, we evaluated the performance of the leased stores and the associated markets in relation to our overall real estate strategies, which resulted in the determination that renewal options would not be reasonably certain in determining the expected lease term. Adoption of the new standard resulted in the recording of additional net lease assets and lease liabilities of approximately $110.4 million and $110.7 million, respectively. The standard did not materially impact our consolidated net earnings and had no impact on cash flows. See Note 13 "Lease Accounting" for further details.

In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract". This ASU aligns the accounting treatment for capitalizing implementation costs incurred by customers in cloud computing arrangements in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This guidance is effective for the Company on January 1, 2020. Early adoption is permitted. The amendments in this update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently assessing the effect that this ASU will have on our financial position, results of operations, and disclosures but does not expect this update to have a material impact on the Company's consolidated financial statements.

Revenue Recognition

Marketing segment

Petroleum product sales (at retail). For our retail store locations, the revenue related to petroleum product sales is recognized as the fuel is pumped to our customers. The transaction price at the pump typically includes some portion of sales or excise taxes as levied in the respective jurisdictions. Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid. Our customers typically use a mixture of cash, checks, credit cards and debit cards to pay for our products as they are received. We have accounts receivable from the various credit/debit card providers at any point in time related to product sales made on credit cards and debit cards. These receivables are typically collected in two to seven days, depending on the terms with the particular credit/debit card providers. Payment fees retained by the credit/debit card providers are recorded as station and other operating expenses.

Petroleum product sales (at wholesale). Our sales of petroleum products at wholesale are generally recorded as revenue when the deliveries have occurred and legal ownership of the product has transferred to the customer. Title transfer for bulk refined product sales typically occurs at pipeline custody points and upon trucks loading at product terminals. For bulk pipeline sales, we record receivables from customers that are generally collected within a week from custody transfer date. For our rack product sales, the majority of our customers' accounts are drafted by us within 10 days from product transfer.

Merchandise sales. For our retail store locations, the revenue related to merchandise sales is recognized as the customer completes their purchase at our locations. The transaction price typically includes some portion of sales tax as levied in the respective jurisdictions. Those taxes that are collected for remittance to governmental entities on a pass through basis are not recognized as revenue and they are recorded to a liability account until they are paid. As noted above, a mixture of payment types are used for these revenues and the same terms for credit/debit card receivables are realized.

The most significant judgment with respect to merchandise sales revenue is determining whether we are the principal or agent for some categories of merchandise such as lottery tickets, lotto tickets, newspapers and other small categories of merchandise. For scratch-off lottery tickets, we have determined we are the principal in the majority of the jurisdictions and therefore we record those sales on a gross basis. We have some categories of merchandise (such as lotto tickets) where we are the agent and the revenues recorded for those transactions are our net commission only.

In June 2018, the Company initiated a loyalty pilot program through a limited number of its retail locations. The customers earn rewards based on their spending or other promotional activities. This program creates a performance obligation which requires us to defer a portion of sales revenue to the loyalty program participants until they redeem their rewards. The rewards may be redeemed for merchandise or cash discounts on fuel purchases. The program was rolled out chain-wide in March 2019. The deferred revenues recorded in the three and nine months ended September 30, 2019 were immaterial.

RINs sales. For the sale of RINs, we recognize revenue when the RIN is transferred to the counter-party and the sale is completed. Receivables from our counter-parties related to the RIN sales are typically collected within five days of the sale.

Other revenues. Items reported as other operating revenues include collection allowances for excise and sales tax and other miscellaneous items and are recognized as revenue when the transaction is completed.

Revenue Recognition

Revenue is recognized when obligations under the terms of a contract with our customers are satisfied; generally, this occurs with the transfer of control of our petroleum products, convenience merchandise, Renewable Identification Numbers ("RINs") and other assets to our third-party customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Excise and sales tax that we collect where we have determined we are the principal in the transaction have been recorded as revenue on a jurisdiction-by-jurisdiction basis.

The Company enters into buy/sell and similar arrangements when petroleum products are held at one location but are needed at a different location. The Company often pays or receives funds related to the buy/sell arrangements based on location or quality differences. The Company continues to account for these transactions as non-monetary exchanges under existing accounting guidance and typically reports these on a net basis in the Consolidated Statements of Income.

Lease Accounting

Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term.

Leases [Abstract]

Lease Accounting

Lease Accounting

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

As the implicit interest rate is not readily determinable in most of the Company's lease agreements, the Company uses its estimated secured incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.

Lessor — We have various arrangements for certain spaces for food service and vending equipment under which we are the lessor. These leases meet the criteria for operating lease classification. Lease income associated with these leases is immaterial.

Lessee —We lease land for 216 stations, one terminal, a hangar and various equipment. Our lease agreements do not contain any material residual value guarantees and approximately 102 sites leased from Walmart contain restrictive covenants, though the restrictions are deemed to have an immaterial impact.

Asset Retirement Obligations (ARO)

Asset Retirement Obligation Disclosure [Abstract]

Asset Retirement Obligations (ARO)

Asset Retirement Obligations (ARO)

The majority of the ARO recognized by the Company at September 30, 2019 and December 31, 2018 is 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.

(Millions of dollars)	September 30, 2019			December 31, 2018
Balance at beginning of period	$	30.7		$	28.2
Accretion expense	1.6			2.0
Settlements of liabilities	(0.2		)	(0.3		)
Liabilities incurred	0.2			0.8
Balance at end of period	$	32.3		$	30.7

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.

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 July 24, 2019, the Board of Directors approved an up to $400 million share repurchase program to be executed over the two-year period ending July 2021. Purchases may be effected in the open market, through privately negotiated transactions, through one or more accelerated stock repurchase programs, through a combination of the foregoing or in any other manner in the discretion of management. Purchases will be made subject to available cash, market conditions and compliance with our financing arrangements at any time during the period of authorization. We may use cash from operations as well as draws under our credit facilities to effect purchases.

Prior to the July authorization, the Company had continued to conduct share repurchases under quarterly allocations in line with its past practice, subject to market conditions and cash availability. For the nine months ended September 30, 2019, the Company acquired 1,597,731 shares of common stock for an average price of $87.09 per share including brokerage fees and for the nine months ended September 30, 2018, 1,994,632 shares were repurchased for an average price of $72.39 per share.

The following table provides a reconciliation of basic and diluted earnings per share computations for the three and nine months ended September 30, 2019 and 2018:

	Three Months Ended September 30,				Nine Months Ended September 30,
(Millions of dollars, except share and per share amounts)	2019		2018		2019		2018
Earnings per common share:

Earnings per common share	$	2.20	$	1.40	$	3.35	$	4.15

	Three Months Ended September 30,				Nine Months Ended September 30,
(Millions of dollars, except share and per share amounts)	2019		2018		2019		2018
Earnings per common share - assuming dilution:
Net income per share - diluted
Net income attributable to common stockholders	$	69.2	$	45.0	$	107.2	$	136.1
Weighted average common shares outstanding (in thousands)	31,447		32,213		31,961		32,815

Dilutive share-based awards	257		323		228		327
Weighted average common shares outstanding - assuming dilution (in thousands)	31,704		32,536		32,189		33,142
Earnings per common share assuming dilution	$	2.18	$	1.38	$	3.33	$	4.11

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.

Actual results may differ from these estimates.

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.

Recently Issued Accounting Standards— 

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 by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under current GAAP. ASU 2016-02 requires that a lessee should recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. We adopted ASU 2016-02 as of January 1, 2019, using the modified retrospective approach. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification. We also elected the practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements. In addition, we elected the hindsight practical expedient to determine the lease term for existing leases. Our election of the hindsight practical expedient resulted in the shortening of lease terms for certain existing leases and the useful lives of corresponding leasehold improvements. In our application of hindsight, we evaluated the performance of the leased stores and the associated markets in relation to our overall real estate strategies, which resulted in the determination that renewal options would not be reasonably certain in determining the expected lease term. Adoption of the new standard resulted in the recording of additional net lease assets and lease liabilities of approximately $110.4 million and $110.7 million, respectively. The standard did not materially impact our consolidated net earnings and had no impact on cash flows. See Note 13 "Lease Accounting" for further details.

In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract". This ASU aligns the accounting treatment for capitalizing implementation costs incurred by customers in cloud computing arrangements in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This guidance is effective for the Company on January 1, 2020. Early adoption is permitted. The amendments in this update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently assessing the effect that this ASU will have on our financial position, results of operations, and disclosures but does not expect this update to have a material impact on the Company's consolidated financial statements.
