		Note 1 — Description of Business and Basis of Presentation
	Description of business — The business of Murphy USA Inc. (“Murphy USA” or the “Company”) and its subsidiaries primarily consists of the U.S. retail marketing business that was separated from its former parent company, Murphy Oil Corporation (“Murphy Oil” or “Parent”), plus an ethanol production facility and other assets, liabilities and operating expenses of Murphy Oil that were associated with supporting the activities of the U.S. retail marketing operations. The separation was approved by the Murphy Oil board of directors on August 7, 2013, and was completed on August 30, 2013 through the distribution of 100% of the outstanding capital stock of Murphy USA to holders of Murphy Oil common stock on the record date of August 21, 2013. Murphy Oil stockholders of record received one share of Murphy USA common stock for every four shares of Murphy Oil common stock. The spin-off was completed in accordance with a separation and distribution agreement entered into between Murphy Oil and Murphy USA. Following the separation, Murphy USA is an independent, publicly traded company, and Murphy Oil retains no ownership interest in Murphy USA.

	Murphy USA markets refined products through a network of retail gasoline stations and unbranded wholesale customers. Murphy USA’s owned retail stations are almost all located in close proximity to Walmart stores in 23 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 March 31, 2014, Murphy USA had a total of 1,214 Company stations. In October 2009, Murphy USA acquired an ethanol production facility located in Hankinson, North Dakota, which was subsequently sold in December 2013 and is reflected as discontinued operations for all periods presented. The Company also acquired a partially constructed ethanol production facility in Hereford, Texas, in late 2010. The Hereford facility is designed to produce 105 million gallons of corn-based ethanol per year, and it began operations near the end of the first quarter of 2011.

In October 2009, Murphy USA acquired an ethanol production facility located in Hankinson, North Dakota. The facility was originally designed to produce 110 million gallons of corn-based ethanol per year. Expansion of the plant occurred during 2012, bringing the overall ethanol production capacity to 135 million gallons per year and the plant was sold in December 2013 with all its financial results now being presented as discontinued operations. The Company acquired a partially constructed ethanol production facility in Hereford, Texas, in late 2010. The Hereford facility is designed to produce 105 million gallons of corn-based ethanol per year, and it began operations near the end of the first quarter of 2011.

		The contributed assets of Murphy Oil included in the Company’s financial statements also include buildings, real estate, an airplane and computer equipment and software that are used to support the operating activities of Murphy USA.
	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 for $1.00. Murphy USA was formed solely in contemplation of the separation and until the separation was completed on August 30, 2013, it had not commenced operations and had no material assets, liabilities, or commitments. Accordingly the accompanying consolidated and combined financial statements reflect the combined historical results of operations, financial position and cash flows of the Murphy Oil subsidiaries and certain assets, liabilities and operating expenses of Murphy Oil that comprise Murphy USA, as described above, as if such companies and accounts had been combined for all periods presented prior to August 30, 2013. All significant intercompany transactions and accounts within the combined financial statements have been eliminated.

All significant intercompany transactions and accounts within the combined financial statements have been eliminated.
	The assets and liabilities in these consolidated and combined financial statements at March 31, 2014 have been reflected on a historical basis. Any periods presented that include dates prior to August 30, 2013 are periods when all of the assets and liabilities shown were 100 percent owned by Murphy Oil and represented operations of Murphy USA prior to the separation. For the period prior to separation, the consolidated and combined statements of income also include expense allocations for certain corporate functions historically performed by Murphy Oil, including allocations of general corporate expenses related to executive oversight, accounting, treasury, tax, legal, procurement and information technology. These allocations are based primarily on specific identification, headcount or computer utilization. Murphy USA’s management believes the assumptions underlying the consolidated and combined financial statements, including the assumptions regarding the allocation of general corporate expenses from Murphy Oil, are reasonable. However, these consolidated and combined financial statements may not include all of the actual expenses that would have been incurred had the Company been a stand-alone company during the period prior to separation and may not reflect the combined results of operations, financial position and cash flows had the Company been a stand-alone company during the entirety of the periods presented.

	Interim Financial Information — The interim period financial information presented in these consolidated and combined financial statements is unaudited and includes all known accruals and adjustments, in the opinion of management, necessary for a fair presentation of the consolidated and combined 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.

Significant Accounting Policies [Abstract]	'
Significant Accounting Policies	'
	Note 2 – Significant Accounting Policies

	PRINCIPLES OF COMBINATION – These consolidated and combined financial statements were prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of Murphy USA Inc. and selected subsidiaries, and certain assets, liabilities, and expenses of Murphy Oil Corporation for all periods prior to August 30, 2013. All significant intercompany accounts and transactions within the consolidated and combined entity have been eliminated.
	REVENUE RECOGNITION – Revenues from sales of refined petroleum products are recorded when deliveries have occurred and legal ownership of the commodity transfers to the customer, which may include related party sales to other subsidiaries of Murphy Oil. Title transfer for bulk refined products generally occur at pipeline custody points or upon truck loading at product terminals. Refined products sold at retail stations are recorded when the customer takes delivery at the pump. Merchandise revenues are recorded at the point of sale. Rebates from vendors are recognized as a reduction of cost of goods sold when the related inventory item is sold. Incentives that are derived from contractual provisions are accrued based on past experience, when estimable, and are recognized in cost of goods sold.
	The Company enters into buy/sell and similar arrangements when petroleum products are held at one location but are needed at a different location. The Company often pays or receives funds related to the buy/sell arrangement based on location or quality differences. The Company accounts for such transactions on a net basis in its Consolidated and Combined Income Statements.
	SHIPPING AND HANDLING COSTS – Costs incurred for the shipping and handling of motor fuel are included in Petroleum product cost of goods sold in the income statement. Costs incurred for the shipping and handling of convenience store merchandise are included in Merchandise cost of goods sold in the income statement.
	TAXES COLLECTED FROM CUSTOMERS AND REMITTED TO GOVERNMENT AUTHORITIES – Excise and other taxes collected on sales of refined products and remitted to governmental agencies are included in revenues and costs and operating expenses in the Combined Income Statements. Excise taxes on petroleum products collected and remitted were $1,884,035,000 in 2013, $1,962,660,000 in 2012, and $1,831,550,000 in 2011.
	CASH EQUIVALENTS – Short-term investments, which include government securities, money market funds and other instruments with government securities as collateral, that have an original maturity of three months or less from the date of purchase are classified as cash equivalents.
	MARKETABLE SECURITIES – The Company classifies investments in marketable securities as available-for-sale or held-to-maturity. The Company does not typically classify any investments as trading. Available-for-sale securities are carried at fair value with the unrealized gain or loss, net of tax, reported in other comprehensive income. Held-to-maturity securities are recorded at amortized cost. Premiums and discounts are amortized or accreted into earnings over the life of the related available-for-sale or held-to-maturity security. Dividend and interest income is recognized when earned. Unrealized losses considered to be other than temporary are recognized currently in earnings. The cost of securities sold is based on the specific identification method. The fair value of investment securities is determined by available market prices.
	ACCOUNTS RECEIVABLE – The Company’s accounts receivable are recorded at the invoiced amount and do not bear interest. The accounts receivable primarily consists of amounts owed to the Company from credit card companies and by customers for sales of refined petroleum products and ethanol. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses on these receivables. The Company reviews this allowance for adequacy at least quarterly and bases its assessment on a combination of current information about its customers and historical write-off experience. Any trade accounts receivable balances written off are charged against the allowance for doubtful accounts. The Company has not experienced any significant credit-related losses in the past three years.
	INVENTORIES – Inventories of most finished products are valued at the lower of cost, generally applied on a last-in, first-out (“LIFO”) basis, or market. Any increments to LIFO inventory volumes are valued based on the first purchase price for these volumes during the year. Merchandise inventories held for resale are carried at average cost. Materials and supplies are valued at the lower of average cost or estimated value. Distillers dried grain with solubles (“DDGS”), wet distillers grain with solubles (“WDGS”) and corn inventories are valued at the lower of cost, applied on a first-in, first-out (“FIFO”) basis, or market.

	VENDOR ALLOWANCES AND REBATES – Murphy USA receives payments for vendor allowances, volume rebates and other related payments from various suppliers of its convenience store merchandise. Vendor allowances for price markdowns are credited to merchandise cost of goods sold during the period the related markdown is recognized. Volume rebates of merchandise are recorded as reductions to merchandise cost of goods sold when the merchandise qualifying for the rebate is sold. Slotting and stocking allowances received from a vendor are recorded as a reduction to cost of sales over the period covered by the agreement.
	PROPERTY, PLANT AND EQUIPMENT – Additions to property, plant and equipment, including renewals and betterments, are capitalized and recorded at cost. Certain marketing facilities are primarily depreciated using the composite straight-line method with depreciable lives ranging from 16 to 25 years. Ethanol plants, gasoline stations and other assets are depreciated over 3 to 45 years by individual unit on the straight-line method. Gains and losses on asset disposals or retirements are included in income as a separate component of other income.
	IMPAIRMENT OF ASSETS – Long-lived assets, which include property and equipment and finite-lived intangible assets, are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. A long-lived asset is not recoverable if its carrying amount exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. If a long-lived asset is not recoverable, an impairment loss is recognized for the amount by which the carrying amount of the long-lived asset exceeds its fair value, with fair value determined based on discounted estimated net cash flows or other appropriate methods.
	TURNAROUNDS – Primary processing units are scheduled for major maintenance activities known as turnarounds at periodic intervals at the Company’s ethanol plant. Turnaround work associated with various other less significant units at the Company’s facilities will vary depending on operating requirements and events. The Company defers turnaround costs incurred and amortizes such costs through Station and other operating expenses over the period until the next scheduled turnaround. All other maintenance and repairs are expensed as incurred.
	ASSET RETIREMENT OBLIGATIONS – The Company records a liability for asset retirement obligations (“ARO”) equal to the fair value of the estimated cost to retire an asset. The ARO liability is initially recorded in the period in which the obligation meets the definition of a liability, which is generally when the asset is placed in service. The ARO liability is estimated using existing regulatory requirements and anticipated future inflation rates. When the liability is initially recorded, the Company increases the carrying amount of the related long-lived asset by an amount equal to the original liability. The liability is increased over time to reflect the change in its present value, and the capitalized cost is depreciated over the useful life of the related long-lived asset. The Company reevaluates the adequacy of its recorded ARO liability at least annually. Actual costs of asset retirements such as dismantling service stations and site restoration are charged against the related liability. Any difference between costs incurred upon settlement of an asset retirement obligation and the recorded liability is recognized as a gain or loss in the Company’s earnings.
	ENVIRONMENTAL LIABILITIES – A liability for environmental matters is established when it is probable that an environmental obligation exists and the cost can be reasonably estimated. If there is a range of reasonably estimated costs, the most likely amount will be recorded, or if no amount is most likely, the minimum of the range is used. Related expenditures are charged against the liability. Environmental remediation liabilities have not been discounted for the time value of future expected payments. Environmental expenditures that have future economic benefit are capitalized.
	INCOME TAXES – The Company accounts for income taxes using the asset and liability method as if Murphy USA was a separate tax payer rather than a member of Murphy Oil’s consolidated income tax return. Under this method, income taxes are provided for amounts currently payable and for amounts deferred as tax assets and liabilities based on differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. Deferred income taxes are measured using the enacted tax rates that are assumed will be in effect when the differences reverse.

	The Company’s results of operations were included in the consolidated federal income tax return of Murphy Oil prior to the separation, while in most cases, these results have been included in the various state tax returns of Murphy USA historically. For these financial statements, federal and state income taxes have been computed and recorded as if the Company filed separate federal and state income tax returns. Federal and state income tax benefits of operating losses generated are recognized to the extent that they could be expected to reduce federal income tax expense for the Company via a carryback to a previous year or carried forward for use in a subsequent year. The calculations of current and deferred income taxes, therefore, require use of certain assumptions, allocations and estimates that management believes are reasonable to reflect the Company’s income taxes as a stand-alone taxpayer. The Company has elected to classify any interest expense and penalties related to the underpayment of income taxes in Income tax expense in the Consolidated and Combined Income Statements.
	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES – The fair value of a derivative instrument is recognized as an asset or liability in the Company’s Consolidated and Combined Balance Sheets. Upon entering into a derivative contract, the Company may designate the derivative as either a fair value hedge or a cash flow hedge, or decide that the contract is not a hedge, and therefore, recognize changes in the fair value of the contract in earnings. The Company documents the relationship between the derivative instrument designated as a hedge and the hedged items as well as its objective for risk management and strategy for use of the hedging instrument to manage the risk. Derivative instruments designated as fair value or cash flow hedges are linked to specific assets and liabilities or to specific firm commitments or forecasted transactions. The Company assesses at inception and on an ongoing basis whether a derivative instrument used as a hedge is highly effective in offsetting changes in the fair value or cash flows of the hedged item. A derivative that is not a highly effective hedge does not qualify for hedge accounting. Changes in the fair value of a qualifying fair value hedge are recorded in earnings along with the gain or loss on the hedged item. Changes in the fair value of a qualifying cash flow hedge are recorded in other comprehensive income until the hedged item is recognized in earnings. When the income effect of the underlying cash flow hedged item is recognized in the Statement of Income, the fair value of the associated cash flow hedge is reclassified from other comprehensive income into earnings. Ineffective portions of a cash flow hedge derivative’s change in fair value are recognized currently in earnings. If a derivative instrument no longer qualifies as a cash flow hedge and the underlying forecasted transaction is no longer probable of occurring, hedge accounting is discontinued and the gain or loss recorded in other comprehensive income is recognized immediately in earnings. See Note 13 and Note 16 for further information about the Company’s derivatives.
	STOCK-BASED COMPENSATION – The fair value of awarded stock options, restricted stock and restricted stock units is determined based on a combination of management assumptions for awards issued subsequent to the separation from Murphy Oil and the previously calculated fair market value of awards that were replaced with Murphy USA awards in connection with the separation. Murphy Oil used the Black-Scholes option pricing model for computing the fair value of stock options. The primary assumptions made by management included the expected life of the stock option award and the expected volatility of Murphy Oil’s common stock prices. Murphy Oil used both historical data and current information to support its assumptions. Stock option expense is recognized on a straight-line basis over the respective vesting period of two or three years. Murphy Oil used a Monte Carlo valuation model to determine the fair value of performance-based restricted stock and restricted stock units and the related expense is recognized over the three-year vesting period. Management estimates the number of stock options and performance-based restricted stock and restricted stock units that will not vest and adjusts its compensation expense accordingly. Differences between estimated and actual vested amounts are accounted for as an adjustment to expense when known. See Note 11 for a discussion of the basis of allocation of such costs.
	NET INVESTMENT BY FORMER PARENT– The Net investment by former parent represents a net balance reflecting Murphy Oil’s initial investment in the Company and subsequent adjustments resulting from the operations of the Company and various transactions between the Company and Murphy Oil. The balance is the result of the Company’s participation in Murphy Oil’s centralized cash management program under which all the Company’s cash receipts are remitted to Murphy Oil and all cash disbursements are funded by Murphy Oil. The net balance includes amounts due from or owed to Murphy Oil. Other transactions affecting the Net investment by Murphy Oil include general and administrative expenses incurred by Murphy Oil and allocated to the Company. There are no terms of settlement or interest charges associated with the Net investment by Murphy Oil balance. Changes in amounts owed to or due from Murphy Oil are included in financing activities in the Statements of Cash Flows.

	USE OF ESTIMATES – In preparing the financial statements of the Company in conformity with U.S. GAAP, management has made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities. Actual results may differ from the estimates. On an ongoing basis, we review our estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.

Otherwise, the expenses related to services provided to the Company by Murphy Oil were allocated to Murphy USA based on relative percentages of headcount or other appropriate methods depending on the nature of each type of cost to be allocated.
	Charges for functions historically provided to the Company by Murphy Oil were primarily attributable to Murphy Oil’s performance of many shared services that the Company benefitted from, such as treasury, tax, accounting, risk management, legal, internal audit, procurement, human resources, investor relations and information technology. Murphy USA also participated in certain Murphy Oil insurance, benefit and incentive plans. The Consolidated and Combined Statements of Income reflect charges from Murphy Oil and its other subsidiaries for these services of $0 and $20,649,000 for the three months ended March 31, 2014 and 2013. Included in the charges above for the period ended March 31, 2013 are amounts recognized for stock-based compensation expense (Note 8), as well as net periodic benefit expense associated with the Parent’s retirement plans (Note 9).

		Transition Services Agreement
	In conjunction with the separation, we entered into a Transition Services Agreement with Murphy Oil on August 30, 2013. This Transition Services Agreement sets forth the terms on which Murphy Oil provides to us, and we provide to Murphy Oil, on a temporary basis, certain services or functions that the companies have historically shared. Transition services include administrative, payroll, human resources, information technology and network transition services, tax, treasury and other support and corporate services. The Transition Services Agreement provides for the provision of specified transition services generally for a period of up to eighteen months, with a possible extension of six months, on a cost basis. We record the fee Murphy Oil charges us for these services as a component of general and administrative expenses.

	In November 2013, the Company announced that it had entered into negotiations to sell its Hankinson, North Dakota ethanol production facility as part of management’s strategic plan to exit non-core businesses. On December 19, 2013, the Company sold its wholly-owned subsidiary Hankinson Renewable Energy, LLC which owned and operated an ethanol manufacturing facility in Hankinson, North Dakota, and its related assets for $170,000,000 plus working capital adjustments of approximately $3,118,000. During January 2014, the final adjustments to working capital were made and the Company received an additional $1.1 million in sales proceeds which has been included in discontinued operations for the period. The Company has accounted for all operations related to Hankinson Renewable, LLC as discontinued operations for all periods presented. The after-tax gain from disposal of the subsidiary (including associated inventories) was $52,542,000 in 2013 with an additional $781,000 in 2014 related to the final working capital adjustment.
				In July 2010, the Company announced that it planned to exit the U.S. refining business. On September 30, 2011, the Company sold the Superior, Wisconsin refinery and related assets for $214,000,000, plus certain capital expenditures between July 25 and the date of closing and the fair value of all associated hydrocarbon inventories at these locations. On October 1, 2011, the Company sold its Meraux, Louisiana refinery and related assets for $325,000,000, plus the fair value of associated hydrocarbon inventories. The Company has accounted for the results of the Superior, Wisconsin and Meraux, Louisiana refineries and associated marketing assets as discontinued operations for all periods presented. The after-tax gain from disposal of the two refineries netted to $18,724,000, made up of a gain on the Superior refinery (including associated inventories) of $77,585,000 and a loss on the Meraux refinery (including associated inventories) of $58,861,000. The gain on disposal was based on refinery selling prices, plus the sales of all associated inventories at fair value, which was significantly above the last-in, first-out (“LIFO”) carrying value of the inventories sold. The net gain on sale of the refineries included an after-tax benefit of $179,152,000 from liquidation of inventories carried mostly under the LIFO cost method. The Separation and Distribution Agreement provided for cross-indemnities designed to place financial responsibility for any liabilities arising out of the refineries and related facilities with Murphy Oil.

	At March 31, 2014 and December 31, 2013, the replacement cost (market value) of last-in, first-out (LIFO) inventories exceeded the LIFO carrying value by $313,583,000 and $307,706,000, respectively. Corn based products consisted primarily of corn, dried distillers’ grains with solubles (DDGS) and wet distillers’ grains with solubles (WDGS), and were all valued on a first-in, first-out (FIFO) basis.

	For the period ended March 31, 2014, the LIFO reserve exceeds the FIFO inventory due to the temporary decrement that existed at that date that is expected to be restored at year-end. This decrement is valued at current replacement cost and is recorded in the LIFO reserve account since it is temporary. During the period ended March 31, 2014, the Company recognized a benefit of $17,781,000 related to a decrement that existed at that date that is not expected to be restored at year-end.

						At December 31, 2013 and 2012, the replacement cost (market value) of last-in, first-out (LIFO) inventories exceeded the LIFO carrying value by $307,706,000 and $303,344,000, respectively. Corn based products consisted primarily of corn, dried distillers’ grains with solubles (DDGS) and wet distillers’ grains with solubles (WDGS), and were all valued on a first-in, first-out (FIFO) basis.

						In 2013, inventories valued at LIFO incurred a decrement that resulted in a charge to earnings. The total LIFO impact to pretax income from continuing operations was a decrease of $13,472,000 and an increase of $2,526,000 at December 31, 2013 and 2012, respectively.

Senior Notes

*In connection with the sale of Hankinson Renewable Energy, LLC to Guardian Hankinson, LLC on December 19, 2013, the electrical facilities loan payable including current maturities was assumed by the new owners per the sales agreement.

On August 14, 2013, Murphy Oil USA, Inc., our primary operating subsidiary, issued 6.00% Senior Notes due 2023 (the “Senior Notes”) in an aggregate principal amount of $500 million. The 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 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.

Senior Notes

The 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 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.

We used the net proceeds of the Senior Notes, together with borrowings under the credit facilities, to finance a cash dividend of $650 million from Murphy Oil USA, Inc. to Murphy Oil paid in connection with the separation.

In addition, we are party to a registration rights agreement, which requires us to exchange the Senior Notes for notes eligible for public resale within 360 days of the issuance of the Senior Notes, or alternatively under certain circumstances, to file a shelf registration statement for public resale of the Senior Notes. On March 21, 2014, we filed a registration statement on Form S-4 to exchange these Senior Notes for notes eligible for public resale.

Credit Facilities

On August 30, 2013, we entered into a credit agreement in connection with the separation from Murphy Oil. The credit agreement provides for a committed $450 million asset-based loan (ABL) facility (with availability subject to the borrowing base described below) and a $150 million term facility. It also provides for a $200 million uncommitted incremental facility. The ABL facility is scheduled to mature on August 30, 2018, subject to the ability to extend for two additional one-year periods with the consent of the extending lenders. The term facility is scheduled to mature on August 30, 2016. On August 30, 2013, Murphy Oil USA, Inc. borrowed $150 million under the term facility, together with the net proceeds of the offering of the Senior Notes, to finance a $650 million cash dividend from Murphy Oil USA, Inc. to Murphy Oil.

It also provides for a $200 million uncommitted incremental facility. The ABL facility is scheduled to mature on August 30, 2018, subject to the ability to extend for two additional one-year periods with the consent of the extending lenders. The term facility is scheduled to mature on August 30, 2016. On August 30, 2013, Murphy Oil USA, Inc. borrowed $150 million under the term facility, the proceeds of which were used, together with the net proceeds of the offering of the Senior Notes, to finance the $650 million cash dividend to Murphy Oil.

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

• 100% of eligible cash at such time, plus

100% of eligible cash at such time, plus

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

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

90% of eligible investment grade accounts, plus

• 90% of eligible investment grade accounts, plus

• 80% of eligible product supply/wholesale 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.

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

The ABL facility includes a $75 million sublimit on swingline loans and a $200 million sublimit for the issuance of letters of credit. Swingline loans and letters of credit issued under the ABL facility reduce availability under the ABL facility.

Interest payable on the credit facilities is based on either:

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

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

Interest payable on the credit facilities is based on either:

plus, (A) in the case Adjusted LIBO Rate borrowings, (i) with respect to the ABL facility, spreads ranging from 1.50% to 2.00% per annum depending on the average availability under the ABL facility or (ii) with respect to the term facility, spreads ranging from 2.75% to 3.00% per annum depending on a secured 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 the average availability under the ABL facility or (ii) with respect to the term facility, spreads ranging from 1.75% to 2.00% per annum depending on a secured debt to EBITDA ratio.

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

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

We are obligated to make quarterly principal payments on the outstanding principal amount of the term facility beginning on the first anniversary of the effective date of the credit agreement in amounts equal to 10% of the term loans made on such effective date, with the remaining balance payable on the scheduled maturity date of the term facility. Borrowings under the credit facilities are prepayable at our option without premium or penalty. On October 8, 2013, we elected to prepay $15,000,000 on the term facility with our excess available cash from operations. We are also required to prepay the term facility with the net cash proceeds of certain asset sales or casualty events, subject to certain exceptions. In accordance with the before-mentioned provision, we remitted $65,000,000 on December 23, 2013, with a portion of the proceeds received from the completed sale of the Hankinson, North Dakota ethanol plant. The credit agreement also includes certain customary mandatory prepayment provisions with respect to the ABL facility.

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 the average availability under the ABL facility or (ii) with respect to the term facility, spreads ranging from 2.75% to 3.00% per annum depending on a secured 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 the average availability under the ABL facility or (ii) with respect to the term facility, spreads ranging from 1.75% to 2.00% per annum depending on a secured debt to EBITDA ratio.

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 fixed charge coverage ratio of a minimum of 1.0 to 1.0 when availability for at least three consecutive business days is less than the greater of (a) 17.5% of the lesser of the aggregate ABL facility commitments and the borrowing base and (b) $70,000,000 (including as of the most recent fiscal quarter end on the first date when availability is less than such amount), as well as a maximum secured debt to EBITDA ratio of 4.5 to 1.0 at any time when term facility commitments or term loans thereunder are outstanding. As of December 31, 2013, our fixed charge coverage ratio and the secured leverage ratio were 1.18 and 0.20, respectively.

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.

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.

We are obligated to make quarterly principal payments on the outstanding principal amount of the term facility beginning on the first anniversary of the effective date of the credit agreement in amounts equal to 10% of the term loans made on such effective date, with the remaining balance payable on the scheduled maturity date of the term facility.

	At year-end 2012, the Company wrote down its net investment in the ethanol production facility in Hereford, Texas, taking a pre-tax impairment charge of $60,988,000. The write down was required based on expected weak ethanol production margins at the plant in future periods. Fair value was determined using a discounted cash flow model for three years, plus an estimated terminal value based on a multiple of the last year’s cash flow. Certain key assumptions used in the cash flow model included use of available futures prices for corn and ethanol products. Additional key assumptions included estimated future ethanol and distillers’ grain production levels, estimated future operating expenses, and estimated sales prices for distillers’ grain.

	Note 7— Income Taxes
					Note 10 — Income Taxes
	The Company’s effective income tax rate generally exceeds the U.S. Federal statutory tax rate of 35%. The effective tax rate is calculated as the amount of income tax expense divided by income before income tax expense. For the three-month periods ended March 31, 2014 and 2013, the Company’s effective tax rates were as follows:
					The components of income from continuing operations before income taxes for each of the three years ended December 31, 2013 and income tax expense (benefit) attributable thereto were as follows:

		2014	2013
	Three months ended March 31	38.7%	41.1%

	The effective tax rate for the 2014 and 2013 periods ended March 31 exceeded the U.S. Federal tax rate of 35% primarily due to U.S. state tax expense.					Years Ended December 31,
					(Thousands of dollars)	2013		2012		2011
	The Company was included in Murphy Oil’s tax returns for the periods prior to the separation in multiple jurisdictions that remain subject to audit by taxing authorities. These audits often take years to complete and settle. As of March 31, 2014, the earliest year remaining open for audit and/or settlement in the United States is 2010. Although the Company believes that recorded liabilities for unsettled issues are adequate, additional gains or losses could occur in future periods from resolution of outstanding unsettled matters.
					Income (loss) from continuing operations before income taxes	$	257,677		150,119		310,813
	Under U.S. GAAP the financial statement recognition of the benefit for a tax position is dependent upon the benefit being more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the tax benefit is then measured and recognized at the largest amount that is greater than 50 percent likely of being realized upon ultimate settlement. The Company has not recorded any effect for unrecognized income tax benefits for the periods reported.

					In management’s judgment, the net deferred tax assets in the preceding table will more likely than not be realized as reductions of future taxable income or by utilizing available tax planning strategies.

					Murphy Oil’s tax returns in multiple jurisdictions that include the Company are subject to audit by taxing authorities. These audits often take years to complete and settle. As of December 31, 2013, the earliest year remaining open for audit and/or settlement in the United States is 2010.

	Prior to the separation and distribution, our employees participated in the Murphy Oil 2007 Long-Term Incentive Plan (the “2007 Plan”) and the Murphy Oil 2012 Long-Term Incentive Plan (the “2012 Plan”) and received Murphy Oil restricted stock awards and options to purchase shares of Murphy Oil common stock. While participating in these two plans, costs resulting from share-based payment transactions were allocated and recognized as an expense in the financial statements using a fair value-based measurement method over the periods that the awards vested. Certain employees of the Company have received annual grants in the form of Murphy Oil stock options, restricted stock units and other forms of share based payments prior to the separation and distribution. Accordingly, the Company has accounted for expense for these plans in accordance with SAB Topic 1-B for periods prior to the separation and distribution.	Note 11 — Incentive Plans

Accordingly, the Company has accounted for expense for these plans in accordance with SAB Topic 1-B for periods prior to the separation.
	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 12, 2014 (the “MUSA 2013 Plan”). The MUSA 2013 Plan authorizes the Executive Compensation Committee of our Board of Directors (“the Committee”) to grant non-qualified or incentive stock options, stock appreciation rights, stock awards (including restricted stock and restricted stock unit awards), cash awards, and performance awards to our employees. No more than 5.5 million shares of MUSA common stock may be delivered under the MUSA 2013 Plan and no more than 1 million shares of common stock may be awarded to any one employee, subject to adjustment for changes in capitalization. The maximum cash amount payable pursuant to any “performance-based” award to any participant in any calendar year is $5 million.
		2013 Long-Term Incentive Plan
	On February 11, 2014, the Committee granted nonqualified stock options for 127,400 shares at an exercise price of $39.46 per share under the terms of the MUSA 2013 Plan. The Black-Scholes valuation for these awards is $11.44 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 39,250 time-based restricted units granted at a grant date fair value of $39.46 along with 78,500 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 17 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 $43.41 per unit. For the ROACE portion of the awards, the valuation will be based on the grant date fair value of $39.46 per unit and the number of awards will be periodically assessed to determine the probability of vesting.	Effective August 30, 2013, certain of our employees began to participate in the Murphy USA 2013 Long-Term Incentive Plan, which was subsequently amended and restated effective as of February 12, 2014 (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. Prior to the amendment and restatement of the MUSA 2013 Plan on February 12, 2014, 10 million shares of MUSA common stock were authorized to be delivered under the MUSA 2013 Plan over the life of the plan. Pursuant to the amendment and restatement of the plan effective as of February 12, 2014, this was reduced to 5.5 million shares of common stock. No more than 1 million shares of common stock may be awarded to any one employee, subject to adjustment for changes in capitalization. The maximum cash amount payable pursuant to any “performance-based” award to any participant in any calendar year is $5 million.
		In connection with the separation, stock compensation awards granted under the 2007 Plan and the 2012 Plan by Murphy Oil (pre-separation awards) were adjusted or substituted as follows:
	On March 3, 2014, the Committee also granted 53,475 time-based restricted stock units granted to certain employees with a grant date fair value of $40.00 per unit.		·		Vested stock options were equitably adjusted so that the grantee holds more options to purchase Murphy Oil common stock at a lower strike price.
			·		Unvested stock options and stock appreciation rights held by MUSA employees were replaced with substitute awards of options to purchase shares of MUSA common stock.
	2013 Stock Plan for Non-employee Directors		·		Unvested restricted stock units will be replaced with adjusted, substitute awards for restricted stock units of MUSA common stock. The new awards of restricted stock are intended to generally preserve the intrinsic value of the original award determined as of the separation and distribution date.
			·		Vesting periods of awards were unaffected by the adjustment and substitution, except that for vested Murphy Oil stock options the MUSA employees have until the earlier of two years from the date of the separation or the stated expiration date of the option to exercise the award.
	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.

	For the three months ended March 31, 2014, the Company issued 22,437 restricted stock units to its non-employee directors at a weighted average grant date fair value of $39.07 per share. These shares vest in three years from the grant date.	Awards granted in connection with the adjustment and substitution of awards originally issued under the 2007 Plan and the 2012 Plan are a part of the MUSA 2013 Plan and reduce the maximum number of shares of common stock available for delivery under the MUSA 2013 Plan. During the period from August 30 to December 31, 2013, the Company granted a total of 977,623 awards from the MUSA 2013 Plan which leaves 4,522,377 remaining shares to be granted in future years (after consideration of the amendments made to the MUSA 2013 Plan in February 2014 by the Board of Directors).

	For the three months ended March 31, 2014 and 2013, share based compensation was $2.5 million and $2.8 million, respectively. For the three months ended March 31, 2014 and 2013, cash received from options exercised under all share-based payment arrangements was $13,000 and $0, respectively. The related income tax benefit for tax benefit realized for the tax deductions from options exercised was $5,000 and $0 for the three months ended March 31, 2014 and 2013, respectively.	2013 Stock Plan for Non-employee Directors

	As of March 31, 2014, unrecognized compensation cost related to stock option awards was $3.8 million, which is expected to be recognized over a weighted average period of 1.9 years. Unrecognized compensation cost related to restricted stock awards was $18.1 million, which is expected to be recognized over a weighted average period of 2.9 years.	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 2013, 28,413 time-based restricted stock units were granted under the terms of the Directors Plan which leaves 471,587 shares available to be granted in the future.
		Amounts recognized in the financial statements by the Company with respect to all share-based plans are shown in the following table. All expense prior to August 30, 2013 was incurred under the 2007 Plan and the 2012 Plan while all amounts after August 30, 2013 were incurred in the MUSA 2013 Plan and the Directors Plan.

		Compensation charged against income before income tax benefit		$	9,391			8,416		10,506
		Related income tax benefit recognized in income			3,287			2,946		3,677
		As of December 31, 2013, there was $15,187,000 in compensation costs to be expensed over approximately the next 2.8 years related to unvested share-based compensation arrangements granted by the Company or its predecessor. Total income tax benefits realized by Murphy Oil from tax deductions related to stock option exercises under share-based payment arrangements previously issued by Murphy Oil Corporation were $625,000, $1,851,000, and $1,173,000 for the years ended December 31, 2013, 2012 and 2011, respectively. There were no stock option exercises under the MUSA 2013 Plan as no awards had vested as of December 31, 2013.
		STOCK OPTIONS – The Committee fixes the option price of each option granted at no less than fair market value (FMV) on the date of the grant and fixes the option term at no more than seven years from such date. Each option granted to date under the MUSA 2013 Plan has been nonqualified and has been issued to replace awards of Murphy Oil that were previously granted to employees of the Company prior to the separation from Murphy Oil. The remaining term of each option granted mirrored the remaining term of the original award that it replaced and the exercise price was adjusted based on the terms of the Employee Matters Agreement entered into between the Company and Murphy Oil in connection with the separation. The only stock options issued post separation were to replace the unvested awards of Murphy Oil that were forfeited in conjunction with the separation. Therefore, the accounting for those awards was a continuation of the Murphy Oil fair value that was previously calculated using the Black-Scholes pricing model and used the following original assumptions to calculate the fair value used for expense purposes. Following are the assumptions used originally by Murphy Oil to value the original awards.





				Years ended December 31,
				2012		2011
		Fair value per option grant		$12.37 - $17.74		$
		Fair value per option grant		$12.37 - $17.74		20.34

		Risk-free interest rate		0.55% - 0.77%		2.10%
		Expected life		4.00 yrs. - 5.20 yrs.		5.10 yrs.

		As a result of the separation from Murphy Oil, the unvested Murphy Oil options were replaced with an appropriate number of Company options bearing an exercise price that was adjusted to preserve the intrinsic value near the date of the separation in connection with the terms of the Employee Matters Agreement. The grant date fair values of the options replaced with MUSA 2013 Plan awards range from $32.53 to $40.25. Because of these adjustments, no further Black-Scholes fair values were required to be calculated for the post separation period. The adjustment and substitution of the stock compensation awards occurred in conjunction with the distribution of MUSA common stock to Murphy Oil stockholders. As a result, no grant, exercise, or cancellation activity occurred on MUSA stock compensation awards during the years ended December 31, 2012 or 2011.

		Changes in options outstanding for Company employees during the period from August 30, 2013 to December 31, 2013 are presented in the following table:

	PENSION AND POSTRETIREMENT PLANS — Murphy Oil has defined benefit pension plans that are principally noncontributory and cover most full-time employees. Upon separation from Murphy Oil, all amounts for these plans related to Murphy USA were frozen and retained by Murphy Oil. Therefore, the assets and liabilities related to Murphy USA employees in these plans are not included in these financial statements as Murphy USA is considered to be participating in multiple employer benefit plans due to co-mingling of various plan assets. However, the periodic benefit expense for each period includes the expense of the U.S. benefit plans. All U.S. tax qualified plans meet the funding requirements of federal laws and regulations. Murphy Oil also sponsors health care and life insurance benefit plans, which are not funded, that cover most retired U.S. employees. The health care benefits are contributory; the life insurance benefits are noncontributory. Murphy USA does not expect to have similar pension or post-retirement plans for its employees.
										PENSION AND POSTRETIREMENT PLANS — After separating from Murphy Oil, the Company no longer sponsors or participates in any defined benefit pension plan or post retirement benefit plan for its employees. Prior to the separation, Murphy Oil had defined benefit pension plans that were principally noncontributory and covered most full-time employees. Upon separation from Murphy Oil, all amounts for these plans that involved Murphy USA employees were frozen and retained by Murphy Oil. Therefore, the assets and liabilities related to Murphy USA employees in these plans are not included in these financial statements as Murphy USA was considered to be participating in multiple employer benefit plans due to co-mingling of various plan assets. However, the periodic benefit expense for each period prior to August 30, 2013 includes the expense of the U.S. benefit plans. All U.S. tax qualified plans meet the funding requirements of federal laws and regulations.

										The table that follows provides the components of net periodic benefit expense associated with Company employees for the three years ended December 31, 2013.

	U.S. Health Care Reform — In March 2010, the United States Congress enacted a health care reform law. Along with other provisions, the law (a) eliminated the tax free status of federal subsidies to companies with qualified retiree prescription drug plans that are actuarially equivalent to Medicare Part D plans beginning in 2013; (b) imposes a 40% excise tax on high-cost health plans as defined in the law beginning in 2018; (c) eliminated lifetime or annual coverage limits and required coverage for preventative health services beginning in September 2010; and (d) imposed a fee of $2 (subsequently adjusted for inflation) for each person covered by a health insurance policy beginning in September 2010. The new law did not significantly affect the Company’s consolidated and combined financial statements as of March 31, 2014 and December 31, 2013 and for the three-month periods ended March 31, 2014 and 2013.									Net periodic benefit expense	$	5,485	$	7,695	$	10,544	$	2,786	$	3,583	$	6,547



										The following table provides the weighted-average assumptions used in the measurement of the net periodic benefit expense for the years ended December 31, 2012 and 2011.






											Net Periodic Benefit Expenses
											Pension Benefits Year				Postretirement Benefits Year
											2012		2011		2012		2011
										Discount rate		4.87%		5.50%		4.87%		5.50%
										Expected return on plan assets		6.50%		6.50%		0%		0%
										Rate of compensation increase		4.20%		4.16%		0%		0%


										The discount rates used for purposes of determining the expense are based on the universe of high-quality corporate bonds that are available. Cash flow analyses are performed in which a spot yield curve is used to discount projected benefit payment streams for the most significant plans. The discounted cash flows are used to determine an equivalent single rate which is the basis for selecting the discount rate. Expected plan asset returns are based on long-term expectations for asset portfolios with similar investment mix characteristics. Expected compensation increases were based on anticipated future averages for Murphy Oil.

										U.S. Health Care Reform — In March 2010, the United States Congress enacted a health care reform law. Along with other provisions, the law (a) imposes a 40% excise tax on high-cost health plans as defined in the law beginning in 2018; (b) eliminated lifetime or annual coverage limits and required coverage for preventative health services beginning in September 2010; and (c) imposed a fee of $2 (subsequently adjusted for inflation) for each person covered by a health insurance policy beginning in September 2010. The new law did not significantly affect the Company’s consolidated and combined financial statements as of December 31, 2013 and 2012 and for the three years ended December 31, 2013. The Company continues to evaluate the various components of the law as guidance is issued and cannot predict with certainty all the ways it may impact the Company. However, based on the evaluation performed to date, the Company currently believes that the health care reform law will not have a material effect on its financial condition, results of operations, or cash flows in future periods.

										THRIFT PLAN – At the time of the spin-off, Murphy USA set up a new qualified defined contribution plan for full-time employees with an asset transfer from the Murphy Oil defined contribution plan. Most full-time employees of the Company may participate in savings plans by contributing up to a specified percentage of their base pay. The Company matches contributions at 100% of each employee’s contribution with a maximum match of 6%. In addition, the Company makes profit sharing contributions on an annual basis. Eligible employees receive a stated percentage of their base and incentive pay of 5%, 7%, or 9% determined on a formula that is based on a combination of age and years of service. The Company’s expenses related to this plan were $4,678,000 in 2013, $2,460,000 in 2012 and $1,794,000 in 2011.

										PROFIT SHARING PLAN – Eligible part-time employees may participate in the Company’s noncontributory profit sharing plan. Each year, the Company may make a discretionary employer contribution in an amount determined and authorized at the discretion of the Board of Directors. Eligible employees receive an allocation based on their compensation earned for the year the contribution is allocated. The Company’s expenses related to this plan were $1,861,000 in 2013, $1,627,000 in 2012 and $1,788,000 in 2011.

Financial Instruments And Risk Management

Note 10— Financial Instruments and Risk Management

Note 13 — Financial Instruments and Risk Management

DERIVATIVE INSTRUMENTS — The Company makes limited use of derivative instruments to manage certain risks related to commodity prices. The use of derivative instruments for risk management is covered by operating policies and is closely monitored by the Company’s senior management. The Company does not hold any derivatives for speculative purposes and it does not use derivatives with leveraged or complex features. Derivative instruments are traded primarily with creditworthy major financial institutions or over national exchanges such as the New York Mercantile Exchange (“NYMEX”). To qualify for hedge accounting, the changes in the market value of a derivative instrument must historically have been, and would be expected to continue to be, highly effective at offsetting changes in the prices of the hedged item. To the extent that the change in fair value of a derivative instrument has less than perfect correlation with the change in the fair value of the hedged item, a portion of the change in fair value of the derivative instrument is considered ineffective and would normally be recorded in earnings during the affected period.

The Company is subject to commodity price risk related to corn that it will purchase in the future for feedstock and WDGS that it will sell in the future at its remaining ethanol production facility. At March 31, 2014 and 2013, the Company had open physical delivery commitment contracts for purchase of approximately 3.5 million and 18.7 million bushels of corn, respectively, for processing at its ethanol plants. For the periods ended March 31, 2014 and 2013, the Company had open physical delivery commitment contracts for sale of approximately 0.5 million and 0.9 million equivalent bushels, respectively, of DDGS and WDGS. To manage the price risk associated with certain of these physical delivery commitments which have fixed prices, at March 31, 2014, the Company had outstanding derivative contracts with offsetting long and short volumes of 0.5 million bushels, that mature at future prices in effect on the expected date of delivery under the physical delivery commitment contracts. At March 31, 2013, the Company had a net short volume of 6.0 million bushels of these same outstanding derivative contracts. Additionally, at March 31, 2014 and 2013, the Company had outstanding derivative contracts with a net short volume of 1.9 and 2.1 million bushels of corn to buy back when certain corn inventories are expected to be processed. The impact of marking to market these commodity derivative contracts decreased income before taxes by $0.6 million and increased income before taxes by $0.2 million for the three months ended March 31, 2014 and 2013, respectively.

The Company is subject to commodity price risk related to corn that it will purchase in the future for feedstock and DDGS and WDGS that it will sell in the future at its ethanol production facility. At December 31, 2013 and 2012, the Company had open physical delivery commitment contracts for purchase of approximately 3.1 million and 19.2 million bushels of corn, respectively, for processing at its ethanol plant. For the periods ended December 31, 2013 and 2012, the Company had open physical delivery commitment contracts for sale of approximately 0.5 million and 1.1 million equivalent bushels, respectively, of DDGS and WDGS. To manage the price risk associated with certain of these physical delivery commitments which have fixed prices, at December 31, 2013 and 2012, the Company had outstanding derivative contracts with a net short volume of approximately 0.5 million bushels and net short volume of 6.3 million bushels, respectively, that mature at future prices in effect on the expected date of delivery under the physical delivery commitment contracts. Additionally, at December 31, 2013, the Company had outstanding derivative contracts with a net short volume of 2.0 million bushels of corn to buy back when certain corn inventories are expected to be processed. The impact of marking to market these commodity derivative contracts decreased income before taxes by $0.1 million, increased income before taxes by $2.9 million, and decreased income before taxes by $0.3 million for the three years ended December 31, 2013, 2012 and 2011, respectively.

At March 31, 2014 and December 31, 2013, the fair value of derivative instruments not designated as hedging instruments are presented in the following table.

Assets And Liabilities Measure At Fair Value

Note 13 — Assets and Liabilities Measured at Fair Value

Note 16 — 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 commodity derivatives contracts for corn was determined based on market quotes for No. 2 yellow corn. The change in fair value of commodity derivatives is recorded in Fuel and ethanol cost of goods sold. The carrying value of the Company’s Cash and cash equivalents, Accounts receivable-trade and Trade accounts payable approximates fair value.

The following table presents the carrying amounts and estimated fair values of financial instruments held by the Company at December 31, 2013 and 2012. The fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties. The table excludes Cash and cash equivalents, Accounts receivable-trade, and Trade accounts payable and accrued liabilities, all of which had fair values approximating carrying amounts. The fair value of Current and Long-term debt was estimated based on rates offered to the Company at that time for debt of the same maturities. The Company has off-balance sheet exposures relating to certain financial guarantees and letters of credit. The fair value of these, which represents fees associated with obtaining the instruments, was nominal.

	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.

With respect to the previously owned refinery properties, Murphy Oil retained those liabilities in the Separation and Distribution agreement that was entered into related to the separation on August 30, 2013. With respect to any remaining potential liabilities, the Company believes costs related to these sites will not have a material adverse effect on Murphy USA’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 March 31, 2014, however certain jurisdictions provide reimbursement for these expenses which have been considered in recording the net exposure.

Since no assurance can be given that future recoveries from other sources will occur, the Company has not recorded a benefit for likely recoveries at December 31, 2013, 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 two Superfund sites. For one of these two sites, the Company is being indemnified as to any exposure by Murphy Oil. As to the second 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 either of the Superfund sites at December 31, 2013. 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.

Since the beginning of fiscal 2007, numerous class action lawsuits have been filed in federal courts across the country against petroleum companies and significant retailers in the petroleum industry, in which the plaintiffs generally allege that they received less motor fuel than the defendants agreed to deliver because the defendants measured the amount of motor fuel they delivered in non-temperature adjusted gallons which, at higher temperatures, contain less energy. Murphy USA’s subsidiary, Murphy Oil USA, Inc., was a defendant in eight of these cases. However, on February 10, 2014, Murphy Oil USA, Inc. was dismissed from all cases with prejudice.

	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 $0.5 million per occurrence. As of March 31, 2014, 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 $4.6 million will be sufficient to cover the related liability and that the ultimate disposition of these claims will have no material effect on the Company’s financial position and results of operations.

	The Company was insured under Murphy Oil’s insurance policies for occurrences prior to the completion of the separation. The specifications and insured limits under those policies, however, were at a level consistent with Murphy Oil as a whole. Following the separation, 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 March 31, 2014, the Company had contingent liabilities of $15.3 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.

	In December 2011, the Financial Accounting Standards Board (FASB) issued an accounting standards update that requires enhanced disclosures about financial instruments and derivative instruments that are either offset in the balance sheet or are subject to an enforceable master netting arrangement or similar agreement. The guidance was effective for all interim and annual periods beginning on or after January 1, 2013. These disclosures are presented in Note 13.

	In February 2013, the FASB issued an accounting standards update that requires additional disclosures for reclassification adjustments from accumulated other comprehensive income (AOCI). These additional disclosures include changes in AOCI balances by component and significant items reclassified out of AOCI. These disclosures must be presented either on the face of the affected financial statement or in the notes to the financial statements. The disclosures were effective for the Company beginning in the first quarter of 2013 and are to be provided on a prospective basis. The adoption of this standard did not have any impact on the Company’s consolidated and combined financial statements.

	During the fourth quarter of 2013, the Company sold its Hankinson, North Dakota ethanol plant. This was the largest of the two ethanol plants that were owned by the Company. Because of this sale, the Company was required to reevaluate its operating segments for reporting purposes. After reviewing the quantitative and qualitative aspects of the Company’s segments, it was determined that the remaining ethanol assets did not warrant separate segment presentation. Therefore, the segments for the Company were restated for all prior periods to reflect one remaining operating segment, Marketing. The remaining ethanol assets were recast into the category with the prior Corporate assets and renamed “Corporate and other assets”. In addition, due to the sale of the Hankinson entity, the Company also shows discontinued operations for all periods presented for the prior Hankinson activity. Segment information is as follows:

After reviewing the quantitative and qualitative aspects of the Company’s segments, it was determined that the remaining ethanol assets did not warrant separate segment presentation. Therefore, the segments for the Company were restated for the current period and all prior periods to reflect one remaining operating segment, Marketing. The remaining ethanol assets were recast into the category with the prior Corporate assets and renamed “Corporate and other assets”. In addition, due to the sale of the Hankinson entity, the Company also shows discontinued operations for all periods presented for the prior Hankinson activity. Segment information is as follows:

Description Of Business And Basis Of Presentation [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 for $1.00. Murphy USA was formed solely in contemplation of the separation and until the separation was completed on August 30, 2013, it had not commenced operations and had no material assets, liabilities, or commitments. Accordingly the accompanying consolidated and combined financial statements reflect the combined historical results of operations, financial position and cash flows of the Murphy Oil subsidiaries and certain assets, liabilities and operating expenses of Murphy Oil that comprise Murphy USA, as described above, as if such companies and accounts had been combined for all periods presented prior to August 30, 2013. All significant intercompany transactions and accounts within the combined financial statements have been eliminated.	PRINCIPLES OF COMBINATION – These consolidated and combined financial statements were prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of Murphy USA Inc. and selected subsidiaries, and certain assets, liabilities, and expenses of Murphy Oil Corporation for all periods prior to August 30, 2013. All significant intercompany accounts and transactions within the consolidated and combined entity have been eliminated.

	The assets and liabilities in these consolidated and combined financial statements at March 31, 2014 have been reflected on a historical basis. Any periods presented that include dates prior to August 30, 2013 are periods when all of the assets and liabilities shown were 100 percent owned by Murphy Oil and represented operations of Murphy USA prior to the separation. For the period prior to separation, the consolidated and combined statements of income also include expense allocations for certain corporate functions historically performed by Murphy Oil, including allocations of general corporate expenses related to executive oversight, accounting, treasury, tax, legal, procurement and information technology. These allocations are based primarily on specific identification, headcount or computer utilization. Murphy USA’s management believes the assumptions underlying the consolidated and combined financial statements, including the assumptions regarding the allocation of general corporate expenses from Murphy Oil, are reasonable. However, these consolidated and combined financial statements may not include all of the actual expenses that would have been incurred had the Company been a stand-alone company during the period prior to separation and may not reflect the combined results of operations, financial position and cash flows had the Company been a stand-alone company during the entirety of the periods presented.

	Actual costs that would have been incurred if Murphy USA had been a stand-alone company for the period prior to separation would depend upon multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure.

	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.

Actual results may differ from these estimates.

Revenue Recognition	'	'
		REVENUE RECOGNITION – Revenues from sales of refined petroleum products are recorded when deliveries have occurred and legal ownership of the commodity transfers to the customer, which may include related party sales to other subsidiaries of Murphy Oil. Title transfer for bulk refined products generally occur at pipeline custody points or upon truck loading at product terminals. Refined products sold at retail stations are recorded when the customer takes delivery at the pump. Merchandise revenues are recorded at the point of sale. Rebates from vendors are recognized as a reduction of cost of goods sold when the related inventory item is sold. Incentives that are derived from contractual provisions are accrued based on past experience, when estimable, and are recognized in cost of goods sold.
		The Company enters into buy/sell and similar arrangements when petroleum products are held at one location but are needed at a different location. The Company often pays or receives funds related to the buy/sell arrangement based on location or quality differences. The Company accounts for such transactions on a net basis in its Consolidated and Combined Income Statements.

Shipping And Handling Costs	'	'
		SHIPPING AND HANDLING COSTS – Costs incurred for the shipping and handling of motor fuel are included in Petroleum product cost of goods sold in the income statement. Costs incurred for the shipping and handling of convenience store merchandise are included in Merchandise cost of goods sold in the income statement.

Taxes Collected From Customers And Remitted To Government Authorities	'	'
		TAXES COLLECTED FROM CUSTOMERS AND REMITTED TO GOVERNMENT AUTHORITIES – Excise and other taxes collected on sales of refined products and remitted to governmental agencies are included in revenues and costs and operating expenses in the Combined Income Statements. Excise taxes on petroleum products collected and remitted were $1,884,035,000 in 2013, $1,962,660,000 in 2012, and $1,831,550,000 in 2011.

Cash Equivalents	'	'
		CASH EQUIVALENTS – Short-term investments, which include government securities, money market funds and other instruments with government securities as collateral, that have an original maturity of three months or less from the date of purchase are classified as cash equivalents.

Marketable Securities	'	'
		MARKETABLE SECURITIES – The Company classifies investments in marketable securities as available-for-sale or held-to-maturity. The Company does not typically classify any investments as trading. Available-for-sale securities are carried at fair value with the unrealized gain or loss, net of tax, reported in other comprehensive income. Held-to-maturity securities are recorded at amortized cost. Premiums and discounts are amortized or accreted into earnings over the life of the related available-for-sale or held-to-maturity security. Dividend and interest income is recognized when earned. Unrealized losses considered to be other than temporary are recognized currently in earnings. The cost of securities sold is based on the specific identification method. The fair value of investment securities is determined by available market prices.

Accounts Receivable	'	'
		ACCOUNTS RECEIVABLE – The Company’s accounts receivable are recorded at the invoiced amount and do not bear interest. The accounts receivable primarily consists of amounts owed to the Company from credit card companies and by customers for sales of refined petroleum products and ethanol. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses on these receivables. The Company reviews this allowance for adequacy at least quarterly and bases its assessment on a combination of current information about its customers and historical write-off experience. Any trade accounts receivable balances written off are charged against the allowance for doubtful accounts. The Company has not experienced any significant credit-related losses in the past three years.

Inventories	'	'
		INVENTORIES – Inventories of most finished products are valued at the lower of cost, generally applied on a last-in, first-out (“LIFO”) basis, or market. Any increments to LIFO inventory volumes are valued based on the first purchase price for these volumes during the year. Merchandise inventories held for resale are carried at average cost. Materials and supplies are valued at the lower of average cost or estimated value. Distillers dried grain with solubles (“DDGS”), wet distillers grain with solubles (“WDGS”) and corn inventories are valued at the lower of cost, applied on a first-in, first-out (“FIFO”) basis, or market.

Vendor Allowances And Rebates	'	'
		VENDOR ALLOWANCES AND REBATES – Murphy USA receives payments for vendor allowances, volume rebates and other related payments from various suppliers of its convenience store merchandise. Vendor allowances for price markdowns are credited to merchandise cost of goods sold during the period the related markdown is recognized. Volume rebates of merchandise are recorded as reductions to merchandise cost of goods sold when the merchandise qualifying for the rebate is sold. Slotting and stocking allowances received from a vendor are recorded as a reduction to cost of sales over the period covered by the agreement.

Property, Plant and Equipment	'	'
		PROPERTY, PLANT AND EQUIPMENT – Additions to property, plant and equipment, including renewals and betterments, are capitalized and recorded at cost. Certain marketing facilities are primarily depreciated using the composite straight-line method with depreciable lives ranging from 16 to 25 years. Ethanol plants, gasoline stations and other assets are depreciated over 3 to 45 years by individual unit on the straight-line method. Gains and losses on asset disposals or retirements are included in income as a separate component of other income.

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

Turnarounds	'	'
		TURNAROUNDS – Primary processing units are scheduled for major maintenance activities known as turnarounds at periodic intervals at the Company’s ethanol plant. Turnaround work associated with various other less significant units at the Company’s facilities will vary depending on operating requirements and events. The Company defers turnaround costs incurred and amortizes such costs through Station and other operating expenses over the period until the next scheduled turnaround. All other maintenance and repairs are expensed as incurred.

Asset Retirement Obligations	'	'
		ASSET RETIREMENT OBLIGATIONS – The Company records a liability for asset retirement obligations (“ARO”) equal to the fair value of the estimated cost to retire an asset. The ARO liability is initially recorded in the period in which the obligation meets the definition of a liability, which is generally when the asset is placed in service. The ARO liability is estimated using existing regulatory requirements and anticipated future inflation rates. When the liability is initially recorded, the Company increases the carrying amount of the related long-lived asset by an amount equal to the original liability. The liability is increased over time to reflect the change in its present value, and the capitalized cost is depreciated over the useful life of the related long-lived asset. The Company reevaluates the adequacy of its recorded ARO liability at least annually. Actual costs of asset retirements such as dismantling service stations and site restoration are charged against the related liability. Any difference between costs incurred upon settlement of an asset retirement obligation and the recorded liability is recognized as a gain or loss in the Company’s earnings.

Environmental Liabilities	'	'
		ENVIRONMENTAL LIABILITIES – A liability for environmental matters is established when it is probable that an environmental obligation exists and the cost can be reasonably estimated. If there is a range of reasonably estimated costs, the most likely amount will be recorded, or if no amount is most likely, the minimum of the range is used. Related expenditures are charged against the liability. Environmental remediation liabilities have not been discounted for the time value of future expected payments. Environmental expenditures that have future economic benefit are capitalized.

Income Taxes	'	'
		INCOME TAXES – The Company accounts for income taxes using the asset and liability method as if Murphy USA was a separate tax payer rather than a member of Murphy Oil’s consolidated income tax return. Under this method, income taxes are provided for amounts currently payable and for amounts deferred as tax assets and liabilities based on differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. Deferred income taxes are measured using the enacted tax rates that are assumed will be in effect when the differences reverse.

		The Company’s results of operations were included in the consolidated federal income tax return of Murphy Oil prior to the separation, while in most cases, these results have been included in the various state tax returns of Murphy USA historically. For these financial statements, federal and state income taxes have been computed and recorded as if the Company filed separate federal and state income tax returns. Federal and state income tax benefits of operating losses generated are recognized to the extent that they could be expected to reduce federal income tax expense for the Company via a carryback to a previous year or carried forward for use in a subsequent year. The calculations of current and deferred income taxes, therefore, require use of certain assumptions, allocations and estimates that management believes are reasonable to reflect the Company’s income taxes as a stand-alone taxpayer. The Company has elected to classify any interest expense and penalties related to the underpayment of income taxes in Income tax expense in the Consolidated and Combined Income Statements.

Derivative Instruments And Hedging Activities	'	'
		DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES – The fair value of a derivative instrument is recognized as an asset or liability in the Company’s Consolidated and Combined Balance Sheets. Upon entering into a derivative contract, the Company may designate the derivative as either a fair value hedge or a cash flow hedge, or decide that the contract is not a hedge, and therefore, recognize changes in the fair value of the contract in earnings. The Company documents the relationship between the derivative instrument designated as a hedge and the hedged items as well as its objective for risk management and strategy for use of the hedging instrument to manage the risk. Derivative instruments designated as fair value or cash flow hedges are linked to specific assets and liabilities or to specific firm commitments or forecasted transactions. The Company assesses at inception and on an ongoing basis whether a derivative instrument used as a hedge is highly effective in offsetting changes in the fair value or cash flows of the hedged item. A derivative that is not a highly effective hedge does not qualify for hedge accounting. Changes in the fair value of a qualifying fair value hedge are recorded in earnings along with the gain or loss on the hedged item. Changes in the fair value of a qualifying cash flow hedge are recorded in other comprehensive income until the hedged item is recognized in earnings. When the income effect of the underlying cash flow hedged item is recognized in the Statement of Income, the fair value of the associated cash flow hedge is reclassified from other comprehensive income into earnings. Ineffective portions of a cash flow hedge derivative’s change in fair value are recognized currently in earnings. If a derivative instrument no longer qualifies as a cash flow hedge and the underlying forecasted transaction is no longer probable of occurring, hedge accounting is discontinued and the gain or loss recorded in other comprehensive income is recognized immediately in earnings. See Note 13 and Note 16 for further information about the Company’s derivatives.

Stock-Based Compensation	'	'
		STOCK-BASED COMPENSATION – The fair value of awarded stock options, restricted stock and restricted stock units is determined based on a combination of management assumptions for awards issued subsequent to the separation from Murphy Oil and the previously calculated fair market value of awards that were replaced with Murphy USA awards in connection with the separation. Murphy Oil used the Black-Scholes option pricing model for computing the fair value of stock options. The primary assumptions made by management included the expected life of the stock option award and the expected volatility of Murphy Oil’s common stock prices. Murphy Oil used both historical data and current information to support its assumptions. Stock option expense is recognized on a straight-line basis over the respective vesting period of two or three years. Murphy Oil used a Monte Carlo valuation model to determine the fair value of performance-based restricted stock and restricted stock units and the related expense is recognized over the three-year vesting period. Management estimates the number of stock options and performance-based restricted stock and restricted stock units that will not vest and adjusts its compensation expense accordingly. Differences between estimated and actual vested amounts are accounted for as an adjustment to expense when known. See Note 11 for a discussion of the basis of allocation of such costs.

Net Investment By Former Parent	'	'
		NET INVESTMENT BY FORMER PARENT– The Net investment by former parent represents a net balance reflecting Murphy Oil’s initial investment in the Company and subsequent adjustments resulting from the operations of the Company and various transactions between the Company and Murphy Oil. The balance is the result of the Company’s participation in Murphy Oil’s centralized cash management program under which all the Company’s cash receipts are remitted to Murphy Oil and all cash disbursements are funded by Murphy Oil. The net balance includes amounts due from or owed to Murphy Oil. Other transactions affecting the Net investment by Murphy Oil include general and administrative expenses incurred by Murphy Oil and allocated to the Company. There are no terms of settlement or interest charges associated with the Net investment by Murphy Oil balance. Changes in amounts owed to or due from Murphy Oil are included in financing activities in the Statements of Cash Flows.

Use Of Estimates	'	'
		USE OF ESTIMATES – In preparing the financial statements of the Company in conformity with U.S. GAAP, management has made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities. Actual results may differ from the estimates. On an ongoing basis, we review our estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.
