PART I. FINANCIAL INFORMATION

DEFINITIONS

Within this report, the following terms have these specific meanings:

“Alkylation” means the reaction of propylene or butylene (olefins) with isobutane to form an iso-paraffinic gasoline (inverse of cracking).

“Aromatic oil” is long chain oil that is highly aromatic in nature that is used to manufacture tires and in the production of asphalt.

“BPD” means the number of barrels per calendar day of crude oil or petroleum products.

“BPSD” means the number of barrels per stream day (barrels of capacity in a 24 hour period) of crude oil or petroleum products.

"Biodiesel" means a clean alternative fuel produced from renewable biological resources.

“Black wax crude oil” is a low sulfur, low gravity crude oil produced in the Uintah Basin in Eastern Utah that has certain characteristics that require specific facilities to transport, store and refine into transportation fuels.

“Catalytic reforming” means a refinery process which uses a precious metal (such as platinum) based catalyst to convert low octane naphtha to high octane gasoline blendstock and hydrogen. The hydrogen produced from the reforming process is used to desulfurize other refinery oils and is a primary source of hydrogen for the refinery.

“Cracking” means the process of breaking down larger, heavier and more complex hydrocarbon molecules into simpler and lighter molecules.

“Crude distillation” means the process of distilling vapor from liquid crudes, usually by heating, and condensing the vapor slightly above atmospheric pressure turning it back to liquid in order to purify, fractionate or form the desired products.

“Delayed coker unit” is a refinery unit that removes carbon from the bottom cuts of crude oil to produce unfinished light transportation fuels and petroleum coke.

“Ethanol” means a high octane gasoline blend stock that is used to make various grades of gasoline.

“FCC,” or fluid catalytic cracking, means a refinery process that breaks down large complex hydrocarbon molecules into smaller more useful ones using a circulating bed of catalyst at relatively high temperatures.

“Hydrocracker” means a refinery unit that breaks down large complex hydrocarbon molecules into smaller more useful ones using a fixed bed of catalyst at high pressure and temperature with hydrogen.

“Hydrodesulfurization” means to remove sulfur and nitrogen compounds from oil or gas in the presence of hydrogen and a catalyst at relatively high temperatures.

“Hydrogen plant” means a refinery unit that converts natural gas and steam to high purity hydrogen, which is then used in the hydrodesulfurization, hydrocracking and isomerization processes.

“HF alkylation,” or hydrofluoric alkylation, means a refinery process which combines isobutane and C3/C4 olefins using HF acid as a catalyst to make high octane gasoline blend stock.

“Isomerization” means a refinery process for rearranging the structure of C5/C6 molecules without changing their size or chemical composition and is used to improve the octane of C5/C6 gasoline blendstocks.

“LPG” means liquid petroleum gases.

Table of Content

“Lubricant” or “lube” means a solvent neutral paraffinic product used in passenger and commercial vehicle engine oils, specialty products for metal working or heat transfer and other industrial applications.

"MSAT2" means Control of Hazardous Air Pollutants from Mobile Sources, a rule issued by the U.S. Environmental Protection Agency to reduce hazardous emissions from motor vehicles and motor vehicle fuels.

“MEK” means a lube process that separates waxy oil from non-waxy oils using methyl ethyl ketone as a solvent.

“MMBTU” means one million British thermal units.

“Natural gasoline” means a low octane gasoline blend stock that is purchased and used to blend with other high octane stocks produced to make various grades of gasoline.

“PPM” means parts-per-million.

“Paraffinic oil” is a high paraffinic, high gravity oil produced by extracting aromatic oils and waxes from gas oil and is used in producing high-grade lubricating oils.

“Refinery gross margin” means the difference between average net sales price and average product costs per produced barrel of refined products sold. This does not include the associated depreciation and amortization costs.

“Reforming” means the process of converting gasoline type molecules into aromatic, higher octane gasoline blend stocks while producing hydrogen in the process.

“Roofing flux” is produced from the bottom cut of crude oil and is the base oil used to make roofing shingles for the housing industry.

“RFS2” or advanced renewable fuel standard is a regulatory mandate required by the Energy Independence and Security Act of 2007 that requires 36 billion gallons of renewable fuel to be blended into transportation fuels by 2022. New mandated blending requirements for this standard became effective July 1, 2010.

“ROSE,” or “Solvent deasphalter / residuum oil supercritical extraction,” means a refinery unit that uses a light hydrocarbon like propane or butane to extract non-asphaltene heavy oils from asphalt or atmospheric reduced crude. These deasphalted oils are then further converted to gasoline and diesel in the FCC process. The remaining asphaltenes are either sold, blended to fuel oil or blended with other asphalt as a hardener.

“Scanfiner” is a refinery unit that removes sulfur from gasoline to produce low sulfur gasoline blendstock.

“Sour crude oil” means crude oil containing quantities of sulfur greater than 0.4 percent by weight, while “sweet crude oil” means crude oil containing quantities of sulfur equal to or less than 0.4 percent by weight.

“Vacuum distillation” means the process of distilling vapor from liquid crudes, usually by heating, and condensing the vapor below atmospheric pressure turning it back to a liquid in order to purify, fractionate or form the desired products.

"WCS" means Western Canada Select crude oil and is made up of Canadian heavy conventional and bitumen crude oils blended with sweet synthetic and condensate diluents.

"WTI" means West Texas Intermediate and is a grade of crude oil used as a common benchmark in oil pricing. WTI is a sweet crude oil and has a relatively low density.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)


NOTE 1:	Description of Business and Presentation of Financial Statements

References herein to HollyFrontier Corporation (“HollyFrontier”) include HollyFrontier and its consolidated subsidiaries. In accordance with the Securities and Exchange Commission’s (“SEC”) “Plain English” guidelines, this Quarterly Report on Form 10-Q has been written in the first person. In these financial statements, the words “we,” “our,” “ours” and “us” refer only to HollyFrontier and its consolidated subsidiaries or to HollyFrontier or an individual subsidiary and not to any other person, with certain exceptions. Generally, the words “we,” “our,” “ours” and “us” include Holly Energy Partners, L.P. (“HEP”) and its subsidiaries as consolidated subsidiaries of HollyFrontier, unless when used in disclosures or obligations between HEP and HollyFrontier or its other subsidiaries. These financial statements contain certain disclosures of agreements that are specific to HEP and its consolidated subsidiaries and do not necessarily represent obligations of HollyFrontier. When used in descriptions of agreements and transactions, “HEP” refers to HEP and its consolidated subsidiaries.

We merged with Frontier Oil Corporation (“Frontier”) effective July 1, 2011. Concurrent with the merger, we changed our name from Holly Corporation (“Holly”) to HollyFrontier and changed the ticker symbol for our common stock traded on the New York Stock Exchange to "HFC" (see Note 2). Accordingly, these financial statements include Frontier, its consolidated subsidiaries and the operations of the merged Frontier businesses effective July 1, 2011, but not prior to this date.

We are principally an independent petroleum refiner that produces high-value light products such as gasoline, diesel fuel, jet fuel, specialty lubricant products, and specialty and modified asphalt. We own and operate petroleum refineries that serve markets throughout the Mid-Continent, Southwest and Rocky Mountain regions of the United States. As of March 31, 2012, we:

•

owned and operated a petroleum refinery in El Dorado, Kansas (the “El Dorado Refinery”), two refinery facilities located in Tulsa, Oklahoma (collectively, the “Tulsa Refineries”), a refinery in Artesia, New Mexico that is operated in conjunction with crude oil distillation and vacuum distillation and other facilities situated 65 miles away in Lovington, New Mexico (collectively, the “Navajo Refinery”), a refinery located in Cheyenne, Wyoming (the “Cheyenne Refinery”) and a refinery in Woods Cross, Utah (the “Woods Cross Refinery”);


•	owned and operated NK Asphalt Partners (“NK Asphalt”) which operates various asphalt terminals in Arizona and New Mexico;


•	owned a 75% interest in a 12-inch refined products pipeline from Salt Lake City, Utah to Las Vegas, Nevada, together with terminal facilities in the Cedar City, Utah and North Las Vegas areas (the “UNEV Pipeline”);


•	owned Ethanol Management Company (“EMC”), a products terminal and blending facility near Denver, Colorado and a 50% interest in Sabine Biofuels II, LLC (“Sabine Biofuels”), a biodiesel production facility located in Port Arthur, Texas; and

•

owned a 42% interest in HEP, a consolidated variable interest entity (“VIE”), which includes our 2% general partner interest. HEP owns and operates logistic assets consisting of petroleum product and crude oil pipelines and terminal, tankage and loading rack facilities that principally support our refining and marketing operations in the Mid-Continent, Southwest and Rocky Mountain regions of the United States and Alon USA, Inc.'s (“Alon”) refinery in Big Spring, Texas. Additionally, HEP owns a 25% interest in SLC Pipeline LLC (the “SLC Pipeline”), a 95-mile intrastate pipeline system that serves refineries in the Salt Lake City area.

We have prepared these consolidated financial statements without audit. In management’s opinion, these consolidated financial statements include all normal recurring adjustments necessary for a fair presentation of our consolidated financial position as of March 31, 2012, the consolidated results of operations and comprehensive income for the three months ended March 31, 2012 and 2011 and consolidated cash flows for the three months ended March 31, 2012 and 2011 in accordance with the rules and regulations of the SEC. Although certain notes and other information required by generally accepted accounting principles in the United States (“GAAP”) have been condensed or omitted, we believe that the disclosures in these consolidated financial statements are adequate to make the information presented not misleading. These consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2011 that has been filed with the SEC.

Our results of operations for the three months ended March 31, 2012 are not necessarily indicative of the results of operations to be realized for the year ending December 31, 2012.

Credit is extended based on our evaluation of the customer’s financial condition, and in certain circumstances collateral, such as letters of credit or guarantees, is required. We reserve for doubtful accounts based on our historical loss experience as well as specific accounts identified as high risk, which historically have been minimal. Credit losses are charged to the allowance for doubtful accounts when an account is deemed uncollectible. Our allowance for doubtful accounts was $3.5 million at March 31, 2012 and December 31, 2011.

Inventories: We use the last-in, first-out (“LIFO”) method of valuing inventory. Under the LIFO method, an actual valuation of inventory can only be made at the end of each year based on the inventory levels at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and are subject to the final year-end LIFO inventory valuation.

Goodwill: Goodwill represents the excess of the cost of an acquired entity over the fair value of the assets acquired and liabilities assumed. Goodwill is not subject to amortization and is tested annually, or more frequently if events or circumstances indicate the possibility of impairment. As of March 31, 2012 there have been no impairments to goodwill.

New Accounting Pronouncements

Presentation of Comprehensive Income

Effective January 1, 2012, we adopted the accounting standard update that requires the presentation of net income and other comprehensive income in one continuous statement or in two separate, but consecutive, statements and eliminated the option to present the components of other comprehensive income in the statement of stockholders' equity.

Intangibles — Goodwill and Other: Testing Goodwill for Impairment

Effective January 1, 2012, we adopted the accounting standard update that allows entities an option to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under this option, we no longer are required to calculate the fair value of a reporting unit unless we determine, based on that qualitative assessment, that it is more likely than not that the reporting unit's fair value is less than its carrying amount. The adoption of this accounting standard did not have an impact on our financial condition, results of operations or cash flows.


NOTE 2:	Change in Accounting Principle

At March 31, 2012, we changed our policy of reporting certain same-party accounts receivable and payable amounts in the consolidated balance sheets to reflect a net amount due under contractual netting agreements. Prior to this change, we reported such amounts on a gross basis with a same-party receivable and payable balance presented separately in our balance sheet. GAAP permits a reporting entity to elect a policy of offsetting same-party receivables and payables when such amounts are net settled under legally enforceable contractual setoff provisions. We believe that a net presentation is preferable because it more appropriately presents our economic resources (accounts receivable) and claims against us (accounts payable) and the future cash flows associated with such assets and liabilities. Additionally, we believe a net presentation of such amounts will conform to the predominant practices used by others in our industry. We have applied this change in accounting principle on a retrospective basis and have recast our prior period financial statements.

The following table summarizes the line items affected in our consolidated balance sheet at December 31, 2011:



	As Originally Reported		As Adjusted		Effect of Change
	(In thousands)
Accounts receivable: Crude oil resales	$	743,544	$	5,166	$	(738,378	)

At March 31, 2012, our accounts payable balance is presented net of $890.9 million in crude oil receivables subject to contractual setoff provisions. There was no cumulative impact to retained earnings since this change in accounting principle did not affect earnings.


NOTE 3:	Holly-Frontier Merger

On February 21, 2011, we entered into a merger agreement providing for a “merger of equals” business combination between us and Frontier. The legacy Frontier business operations consist of crude oil refining and the wholesale marketing of refined petroleum products produced at the El Dorado and Cheyenne Refineries and serve markets in the Rocky Mountain and Plains States regions of the United States. On July 1, 2011, North Acquisition, Inc., a direct wholly-owned subsidiary of Holly, merged with and into Frontier, with Frontier surviving as a wholly-owned subsidiary of Holly. Subsequent to the merger and following approval by the post-closing board of directors of HollyFrontier, Frontier merged with and into HollyFrontier, with HollyFrontier continuing as the surviving corporation.

In accordance with the merger agreement, we issued approximately 102.8 million shares of HollyFrontier common stock in exchange for outstanding shares of Frontier common stock to former Frontier stockholders. Each outstanding share of Frontier common stock was converted into 0.4811 shares of HollyFrontier common stock with any fractional shares paid in cash. The aggregate consideration paid in connection with the merger was approximately $3.7 billion. This is based on our July 1, 2011 market closing price of $35.93 and includes a portion of the fair value of the outstanding equity-based awards assumed from Frontier that relates to pre-merger services.

The merger has been accounted for using the acquisition method of accounting with Holly being considered the acquirer of Frontier for accounting purposes. Therefore, the purchase price was allocated to the fair value of the acquired assets and assumed liabilities at the acquisition date, with the excess purchase price being recorded as goodwill. The goodwill resulting from the merger is primarily due to the favorable location of the acquired refining facilities and the expected synergies to be gained from our combined business operations. Goodwill related to this merger is not deductible for income tax purposes.

The following table summarizes our fair value estimates of the Frontier assets and liabilities recognized upon our merger on July 1, 2011:

Our consolidated financial and operating results reflect the operations of the merged Frontier businesses beginning July 1, 2011. Assuming the merger had been consummated on January 1, 2011, pro forma revenues, net income and basic and diluted earnings per share are as follows:



	Three Months Ended March 31, 2011
	(In thousands, except per share amounts)

Sales and other revenues	$	4,235,239
Net income attributable to HollyFrontier stockholders	$	234,066

Adjustments made to derive pro forma net income primarily relate to depreciation and amortization expense to reflect our new basis in the legacy Frontier refining facilities.


NOTE 4:	Holly Energy Partners

HEP, a consolidated VIE, is a publicly held master limited partnership that was formed to acquire, own and operate the petroleum product and crude oil pipeline and terminal, tankage and loading rack facilities that support our refining and marketing operations in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. HEP also owns and operates refined product pipelines and terminals, located primarily in Texas, that serve Alon's refinery in Big Spring, Texas.

As of March 31, 2012, we owned a 42% interest in HEP, including the 2% general partner interest. We are the primary beneficiary of HEP's earnings and cash flows and therefore we consolidate HEP. See Note 19 for supplemental guarantor/non-guarantor financial information, including HEP balances included in these consolidated financial statements. All intercompany transactions with HEP are eliminated in our consolidated financial statements.

HEP has two primary customers (including us) and generates revenues by charging tariffs for transporting petroleum products and crude oil though its pipelines, by charging fees for terminalling refined products and other hydrocarbons, and storing and providing other services at its storage tanks and terminals. Under our long-term transportation agreements with HEP (discussed further below), we accounted for 83% of HEP’s total revenues for the three months ended March 31, 2012. We do not provide financial or equity support through any liquidity arrangements and /or guarantees to HEP.

HEP has outstanding debt under a senior secured revolving credit agreement and its senior notes. With the exception of the assets of HEP Logistics Holdings, L.P., one of our wholly-owned subsidiaries and HEP’s general partner, HEP’s creditors have no recourse

Table of Contents

HOLLYFRONTIER CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited) Continued

to our assets. Any recourse to HEP’s general partner would be limited to the extent of HEP Logistics Holdings, L.P.’s assets, which other than its investment in HEP, are not significant. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries. See Note 12 for a description of HEP’s debt obligations.

At March 31, 2012, we have an agreement to pledge up to 6,000,000 of our HEP common units to collateralize certain crude oil purchases. These units represent a 21% ownership interest in HEP.

HEP has risk associated with its operations. If a major shipper of HEP were to terminate its contracts or fail to meet desired shipping or throughput levels for an extended period of time, revenue would be reduced and HEP could suffer substantial losses to the extent that a new customer is not found. In the event that HEP incurs a loss, our operating results will reflect HEP’s loss, net of intercompany eliminations, to the extent of our ownership interest in HEP at that point in time.

Legacy Frontier Tankage and Terminal Asset Transaction

On November 9, 2011, HEP acquired from us certain tankage, loading rack and crude receiving assets located at our El Dorado and Cheyenne Refineries.

Transportation Agreements

HEP serves our refineries under long-term pipeline and terminal, tankage and throughput agreements expiring from 2019 through 2026. Under these agreements, we pay HEP fees to transport, store and throughput volumes of refined product and crude oil on HEP's pipeline and terminal, tankage and loading rack facilities that result in minimum annual payments to HEP. Under these agreements, the agreed upon tariff rates are subject to annual tariff rate adjustments on July 1 at a rate based upon the percentage change in Producer Price Index (“PPI”) or Federal Energy Regulatory Commission (“FERC”) index. As of March 31, 2012, these agreements result in minimum annualized payments to HEP of $191.8 million.

Since HEP is a consolidated VIE, our transactions with HEP including fees paid under our transportation agreements with HEP are eliminated and have no impact on our consolidated financial statements.


NOTE 5:	Financial Instruments

Our financial instruments consist of cash and cash equivalents, investments in marketable securities, accounts receivable, accounts payable, debt and derivative instruments. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term maturity of these instruments. Debt consists of outstanding principal under HEP's revolving credit agreement (which approximates fair value as interest rates are reset frequently at current interest rates) and senior notes.

Fair value measurements are derived using inputs (assumptions that market participants would use in pricing an asset or liability, including assumptions about risk). GAAP categorizes inputs used in fair value measurements into three broad levels as follows:


•	(Level 1) Quoted prices in active markets for identical assets or liabilities.


•	(Level 2) Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, similar assets and liabilities in markets that are not active or can be corroborated by observable market data.


•	(Level 3) Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes valuation techniques that involve significant unobservable inputs.

The carrying amounts and related estimated fair values of our investments in marketable securities, derivative instruments and the senior notes at March 31, 2012 and December 31, 2011 were as follows:

Level 1 Financial Instruments

Our investments in equity securities and our NYMEX futures contracts are exchange traded and are measured and recorded at fair value using quoted market prices, a Level 1 input. For the three months ended March 31, 2012, we recorded settlements and mark-to-market adjustments on our Level 1 financial instruments that resulted in a $6.4 million pre-tax increase to earnings.

Level 2 Financial Instruments

Investments in marketable debt securities and derivative instruments consisting of commodity price swaps and HEP's interest rate swap are measured and recorded at fair value using Level 2 inputs. With respect to the commodity price and interest rate swap contracts, fair value is based on the net present value of expected future cash flows related to both variable and fixed rate legs of the respective swap agreements. The measurements are computed using market-based observable inputs, quoted forward commodity prices with respect to our commodity price swaps and the forward London Interbank Offered Rate (“LIBOR”) yield curve with respect to HEP's interest rate swap. The fair value of the marketable debt securities and senior notes is based on values provided by a third-party bank, which were derived using market quotes for similar type instruments, a Level 2 input. For the three

months ended March 31, 2012, we recorded settlements and mark-to-market adjustments on our Level 2 financial instruments that resulted in a $27.4 million pre-tax increase to earnings.

Level 3 Financial Instruments

We have entered into certain commodity price swap contracts related to forecasted sales of diesel and unleaded gasoline for which quoted forward market prices are not readily available. The forward rate used to value these price swaps was derived using a projected forward rate using quoted market rates for similar products, adjusted for regional pricing differentials, a Level 3 input. At March 31, 2012, we had a pre-tax unrealized loss in accumulated other comprehensive income related to these contracts. For the three months ended March 31, 2012, we recorded settlements, mark-to-market adjustments and hedge ineffectiveness on our Level 3 commodity price swaps that resulted in a $35.5 million pre-tax charge to earnings.

The following table presents the changes in fair value of the Level 3 assets and liabilities (all related to commodity contracts) for the three months ended March 31, 2012:



	(in thousands)
Asset balance at January 1, 2012	$	31,616
Unrealized losses included in other comprehensive income	(146,769		)

A hypothetical change of 10% to the estimated future cash flows attributable to our Level 3 commodity price swaps would result in an estimated fair value change of approximately $16.0 million.


NOTE 6:	Earnings Per Share

Basic earnings per share is calculated as net income attributable to HollyFrontier stockholders divided by the average number of shares of common stock outstanding. Diluted earnings per share assumes, when dilutive, the issuance of the net incremental shares from variable restricted and variable performance shares. The following is a reconciliation of the denominators of the basic and diluted per share computations for net income attributable to HollyFrontier stockholders:



	Three Months Ended March 31,
	2012		2011
	(In thousands, except per share data)

Earnings attributable to HollyFrontier stockholders	$	241,696	$	84,694
Average number of shares of common stock outstanding	208,531		106,614
Effect of dilutive variable restricted shares and performance share units	607		652
Average number of shares of common stock outstanding assuming dilution	209,138		107,266
Basic earnings per share	$	1.16	$	0.79
Diluted earnings per share	$	1.16	$	0.79


NOTE 7:	Stock-Based Compensation

As of March 31, 2012, we have two principal share-based compensation plans including the Frontier plan that was retained upon the July 1, 2011 merger (collectively, the “Long-Term Incentive Compensation Plan”).

The compensation cost charged against income for these plans was $8.5 million and $1.1 million for the three months ended March 31, 2012 and 2011, respectively. The total income tax benefit recognized in the income statement for share-based compensation arrangements was $3.3 million and $0.4 million for the three months ended March 31, 2012 and 2011, respectively. Our accounting policy for the recognition of compensation expense for awards with pro-rata vesting (substantially all of our awards) is to expense the costs ratably over the vesting periods.

Additionally, HEP maintains share-based compensation plans for HEP directors and select Holly Logistic Services, L.L.C. executives and employees. Compensation cost attributable to HEP’s share-based compensation plans was $0.9 million and $0.7 million for the three months ended March 31, 2012 and 2011, respectively.

Restricted Stock

Under our Long-Term Incentive Compensation Plan, we grant certain officers, other key employees and non-employee directors restricted stock awards with most awards vesting over a period of one to three years. Although ownership of the shares does not transfer to the recipients until after the shares vest, recipients generally have dividend rights on these shares from the date of grant. The vesting for certain key executives is contingent upon certain performance targets being realized. The fair value of each share of restricted stock awarded, including the shares issued to the key executives, is measured based on the market price as of the date of grant and is amortized over the respective vesting period.

A summary of restricted stock activity and changes during the three months ended March 31, 2012 is presented below:

Restricted Stock	Grants		Weighted Average Grant Date Fair Value		Aggregate Intrinsic Value ($000)

Outstanding at January 1, 2012 (non-vested)	1,122,350		$	25.48
Granted	404,577		$	33.81
Vesting and transfer of ownership to recipients	(503,327	)	$	24.24
Outstanding at March 31, 2012 (non-vested)	1,023,600		$	29.38	$	32,909

The total fair value of restricted stock vested and transferred to recipients during the three months ended March 31, 2012 and 2011 was $12.2 million and $2.6 million, respectively. As of March 31, 2012, there was $20.7 million of total unrecognized compensation cost related to non-vested restricted stock grants. That cost is expected to be recognized over a weighted-average period of 1.3 years.

Performance Share Units

Under our Long-Term Incentive Compensation Plan, we grant certain officers and other key employees performance share units, which are payable in stock upon meeting certain criteria over the service period, and generally vest over a period of one to three years. Under the terms of our performance share unit grants, awards are subject to either a "financial performance" or "market performance" criteria.

The fair value of performance share unit awards subject to financial performance criteria is computed using the grant date closing stock price of each respective award grant and will apply to the number of units ultimately awarded. The number of shares ultimately issued for each award will be based on our financial performance as compared to peer group companies over the performance period and can range from zero to 200%. As of March 31, 2012, estimated share payouts for outstanding non-vested performance share unit awards ranged from 150% to 175%.

For the performance share units subject to market performance criteria, performance is calculated as the total shareholder return achieved by HollyFrontier stockholders compared with the average shareholder return achieved by an equally-weighted peer group of independent refining companies over a three-year period. These share unit awards are valued using a Monte Carlo valuation model, which simulates future stock price movements using key inputs including grant date stock prices, expected stock price performance, expected rate of return and volatility of our stock price relative to a peer group over a three-year performance period. These units are payable in stock based on share price performance relative to the defined peer group and can range from zero to 200% of the initial target award.

A summary of performance share unit activity and changes during the three months ended March 31, 2012 is presented below:



Performance Share Units	Grants

Outstanding at January 1, 2012 (non-vested)	774,788
Granted	293,559
Vesting and transfer of ownership to recipients	(235,924	)
Outstanding at March 31, 2012 (non-vested)	832,423

For the three months ended March 31, 2012, we issued 455,333 shares of our common stock having a fair value of $2.7 million related to vested performance share units having a 193% payout. Based on the weighted-average grant date fair value of $28.18 per share, there was $20.2 million of total unrecognized compensation cost related to non-vested performance share units. That cost is expected to be recognized over a weighted-average period of 1.9 years.


NOTE 8:	Cash and Cash Equivalents and Investments in Marketable Securities

Our investment portfolio at March 31, 2012 consisted of cash, cash equivalents and investments in debt securities primarily issued by government and municipal entities. At March 31, 2012, we also held 1,000,000 shares of Connacher Oil and Gas Limited

common stock that were received as partial consideration upon the sale of our Montana refinery in 2006.

We invest in highly-rated marketable debt securities, primarily issued by government and municipal entities that have maturities at the date of purchase of greater than three months. We also invest in other marketable debt securities with the maximum maturity or put date of any individual issue generally not greater than two years from the date of purchase. All of these instruments, including investments in equity securities, are classified as available-for-sale. As a result, they are reported at fair value using quoted market prices. Interest income is recorded as earned. Unrealized gains and losses, net of related income taxes, are reported as a component of accumulated other comprehensive income. Upon sale, realized gains and losses on the sale of marketable securities are computed based on the specific identification of the underlying cost of the securities sold and the unrealized gains and losses previously reported in other comprehensive income are reclassified to current earnings.

The following is a summary of our available-for-sale securities:



	Available-for-Sale Securities
	Amortized Cost		Gross Unrealized Gain		Estimated Fair Value (Net Carrying Amount)
	(In thousands)
March 31, 2012

During the three months ended March 31, 2012, we adjusted goodwill upon finalizing certain fair value estimates that primarily relate to income tax receivables and environmental liabilities that were recognized upon our July 1, 2011 merger with Frontier.


NOTE 11:	Environmental

We expensed $14.3 million and $1.1 million for the three months ended March 31, 2012 and 2011, respectively, for environmental remediation obligations. The accrued environmental liability reflected in our consolidated balance sheets was $63.4 million and $42.2 million at March 31, 2012 and December 31, 2011, respectively, of which $51.1 million and $31.7 million respectively, were classified as other long-term liabilities. These accruals include remediation costs expected to be incurred over an extended period of time. It also includes $15.6 million in environmental liabilities that were assumed upon our merger with Frontier.


NOTE 12:	Debt

HollyFrontier Credit Agreement

We have a $1 billion senior secured credit agreement (the “HollyFrontier Credit Agreement”) with Union Bank, N.A. as administrative agent and BNP Paribas as syndication agent, and certain lenders from time to time party thereto. The HollyFrontier Credit Agreement matures in July 2016 and may be used to fund working capital requirements, capital expenditures, acquisitions and general corporate purposes. Obligations under the HollyFrontier Credit Agreement are collateralized by our inventory, accounts receivables and certain deposit accounts and guaranteed by our material, wholly-owned subsidiaries.

We were in compliance with all covenants at March 31, 2012. At March 31, 2012, we had no outstanding borrowings and outstanding letters of credit totaled $28.5 million under the HollyFrontier Credit Agreement. At that level of usage, the unused commitment was $971.5 million at March 31, 2012.

HEP Credit Agreement

HEP has a $375 million senior secured revolving credit facility (the “HEP Credit Agreement”), with an outstanding balance of $155 million at March 31, 2012, that is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. It is also available to fund letters of credit up to a $50 million sub-limit and to fund distributions to unitholders up to a $30 million sub-limit. In February 2012, HEP amended its previous credit agreement, increasing the size of the credit facility from $275 million to $375 million. The HEP Credit Agreement expires in February 2016.

HEP’s obligations under the HEP Credit Agreement are collateralized by substantially all of HEP’s assets (presented parenthetically in our consolidated balance sheets). Indebtedness under the HEP Credit Agreement is recourse to HEP Logistics Holdings, L.P., its general partner, and guaranteed by HEP’s wholly-owned subsidiaries. Any recourse to the general partner would be limited to the extent of HEP Logistics Holdings, L.P.’s assets, which other than its investment in HEP, are not significant. HEP’s creditors have no other recourse to our assets. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries.

HollyFrontier Senior Notes

Our senior notes consist of the following:


•	9.875% Senior Notes ($291.8 million principal amount maturing June 2017)


•	6.875% Senior Notes ($150 million principal amount maturing November 2018)


•	8.5% Senior Notes ($200 million principal amount maturing September 2016)

At any time when the HollyFrontier Senior Notes are rated investment grade by both Moody’s and Standard & Poor’s and no default or event of default exists, we will not be subject to many of the foregoing covenants. Additionally, we have certain redemption rights under the HollyFrontier Senior Notes.

HollyFrontier Financing Obligation

In October 2009, we sold approximately 400,000 barrels of crude oil tankage at our Tulsa West facility as well as certain crude oil pipeline receiving facilities to an affiliate of Plains All American Pipeline, L.P. (“Plains”) for $40.0 million in cash. In connection with this transaction, we entered into a 15-year lease agreement with Plains, whereby we agreed to pay a fixed monthly fee for the exclusive use of this tankage as well as a fee for volumes received at the receiving facilities purchased by Plains. Additionally, we have a margin sharing agreement with Plains under which we will equally share contango profits with Plains for crude oil purchased by them and delivered to our Tulsa West facility for storage. Due to our continuing involvement in these assets, this sale and lease transaction has been accounted for as a financing obligation. As a result, we retained these assets on our books and recorded a liability representing the $40 million in proceeds received.

HEP Senior Notes

HEP’s senior notes consist of the following:


•	6.25% HEP Senior Notes ($27.3 million principal amount outstanding at March 31, 2012 and redeemed in April 2012)


•	6.5% HEP Senior Notes ($300 million principal amount maturing March 2020)


•	8.25% HEP Senior Notes ($150 million principal amount maturing March 2018)

In March 2012, HEP issued $300 million in aggregate principal amount of 6.5% HEP senior notes maturing March 2020. The $294.8 million in net proceeds were used to fund $157.8 million aggregate principal amount of 6.25% Senior Notes tendered pursuant to a cash tender offer and consent solicitation announced in February 2012, to repay $72.9 million in Promissory Notes due to HollyFrontier, related fees, expenses and accrued interest in connection with these transactions and to repay borrowings under the HEP Credit Agreement. In April 2012, HEP called for redemption $27.3 million aggregate principal amount of 6.25% Senior Notes that remained outstanding following the cash tender offer and consent solicitation.

These HEP senior notes (collectively, the “HEP Senior Notes”) are unsecured and impose certain restrictive covenants, including limitations on HEP’s ability to incur additional indebtedness, make investments, sell assets, incur certain liens, pay distributions, enter into transactions with affiliates, and enter into mergers. At any time when the HEP Senior Notes are rated investment grade by both Moody’s and Standard & Poor’s and no default or event of default exists, HEP will not be subject to many of the foregoing covenants. Additionally, HEP has certain redemption rights under the HEP Senior Notes.

Indebtedness under the HEP Senior Notes is recourse to HEP Logistics Holdings, L.P., its general partner, and guaranteed by HEP’s wholly-owned subsidiaries. However, any recourse to the general partner would be limited to the extent of HEP Logistics Holdings, L.P.’s assets, which other than its investment in HEP, are not significant. HEP’s creditors have no other recourse to our assets. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries.

The carrying amounts of long-term debt are as follows:

NOTE 13: Derivative Instruments and Hedging Activities

Commodity Price Risk Management

Our primary market risk is commodity price risk. We are exposed to market risks related to the volatility in crude oil and refined products, as well as volatility in the price of natural gas used in our refining operations. We periodically enter into derivative contracts in the form of commodity price swaps and futures contracts to mitigate price exposure with respect to:


•	our inventory positions;


•	natural gas purchases;


•	costs of crude oil and related grade differentials;


•	prices of refined products; and


•	our refining margins.

As of March 31, 2012, we have outstanding swap contracts serving as cash flow hedges against price risk on forecasted 2012 and 2013 purchases of 13,008,000 barrels of WTI crude oil and forecasted sales of 6,504,000 barrels of ultra-low sulfur diesel and 6,504,000 barrels of conventional unleaded gasoline. In the aggregate, these cash flow hedges effectively hedge our gross margin on forecasted gasoline and diesel sales, totaling 40,000 BPD through the remaining nine months of 2012, plus an additional 14,000 BPD in the fourth quarter of 2012 and 8,000 BPD in the first quarter of 2013. These contracts have been designated as accounting hedges and are measured quarterly at fair value with offsetting adjustments (gains/losses) recorded directly to other comprehensive income. These fair value adjustments are later reclassified in the statement of income as the hedging instruments mature. Also on a quarterly basis, hedge ineffectiveness is measured by comparing the change in fair value of the swap contracts against the expected future cash inflows/outflows on the respective transaction being hedged.

HOLLYFRONTIER CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited) Continued

For the three months ended March 31, 2012, we recognized settlements on our hedges of forecasted ultra-low sulfur diesel and unleaded gasoline sales of $34.1 million and hedge ineffectiveness of $0.9 million that were recorded as reductions to revenues. Additionally, we recognized settlements on our hedge of forecasted WTI crude oil purchases of $50.5 million that were recorded as reductions to cost products sold.

We have swap contracts that fix our purchase price on forecasted natural gas purchases (8,800,000 MMBTUs through 2012). These contracts are measured quarterly at fair value with offsetting adjustments (gains/losses) recorded directly to operating expense. Also, we have swap contracts that lock in the spread between WCS and WTI crude oil on forecasted purchases (5,970,000 barrels of crude oil through the end of 2013) and NYMEX futures contracts to lock in prices on forecasted sales and purchases of inventory (2,913,000 barrels and 409,000 barrels, respectively, through 2013). These contracts are measured quarterly at fair value with offsetting adjustments (gains/losses) recorded directly to cost of products sold.

For the three months ended March 31, 2012, maturities and fair value adjustments attributable to our economic hedges resulted in increases of $15.0 million and $1.7 million to cost of products sold and operating expenses, respectively. For the three months ended March 31, 2011, maturities and fair value adjustments attributable to our economic hedges resulted in a $3.7 million increase to costs of products sold.

Interest Rate Risk Management

HEP uses interest rate swaps to manage its exposure to interest rate risk.

As of March 31, 2012, HEP has an interest rate swap contract that hedges its exposure to the cash flow risk caused by the effects of LIBOR changes on a $155.0 million credit agreement advance. This interest rate swap effectively converts $155.0 million of LIBOR based debt to fixed rate debt having an interest rate of 0.99% plus an applicable margin, currently 2.25%, which equaled an effective interest rate of 3.24% as of March 31, 2012. This swap matures in February 2016 and has been designated as a cash flow hedge. To date, there has been no ineffectiveness on this cash flow hedge.

At March 31, 2012 , HEP had a pre-tax unrealized loss recorded in accumulated other comprehensive income of $5.5 million that relates to its current and previous cash flow hedging instruments. Of this amount, $4.7 million relates to a cash flow hedge terminated in December 2011 and represents the application of hedge accounting prior to termination. This amount will be amortized as a charge to interest expense through February 2013, the remaining term of the terminated swap contract.

The following table presents balance sheet locations and related fair values of outstanding derivative instruments. These amounts are presented on a gross basis in accordance with GAAP disclosure requirements and do not reflect the netting of asset or liability positions permitted under the terms of master netting arrangements. Therefore, they are not equal to amounts presented in our consolidated balance sheets.

At March 31, 2012, there was a pre-tax net unrealized gain of $15.9 million classified in accumulated other comprehensive income that relates to our commodity cash flow hedges and HEP's cash flow hedge of interest. Assuming commodity prices and interest rates remain unchanged, an unrealized gain of approximately $16.6 million will be effectively transferred from accumulated other comprehensive income into the statement of income as the hedging instruments mature over the next twelve-month period.

In January 2012, our Board of Directors approved a $350 million stock repurchase program to repurchase common stock in the open market or through privately negotiated transactions. The timing and amount of stock repurchases will depend on market conditions, corporate, regulatory and other relevant considerations. The stock repurchase program may be discontinued at any time by the Board of Directors. As of March 31, 2012, we have repurchased 2,146,347 shares at a cost of $64.2 million under this stock repurchase program, of which $10.4 million settled in April 2012.

During the three months ended March 31, 2012, we withheld shares of our common stock from certain employees in the amount of $8.8 million. These witholdings were made under the terms of restricted stock and performance share unit agreements to provide funds for the payment of payroll and income taxes due at the vesting of restricted and performance shares in the case of officers and employees who elected to have shares withheld from vested amounts in order to pay such taxes.

NOTE 16:	Retirement Plan

We sponsor a non-contributory defined benefit retirement plan that covers most legacy Holly non-union employees hired prior to January 1, 2007 and union employees hired prior to July 1, 2010. This retirement plan was closed to new entrants effective either January 1, 2007 (for non-union employees) or July 1, 2010 (for union employees). Effective January 1, 2012, no additional benefits will be accrued under this plan for non-union employee participants and effective May 1, 2012, no additional benefits will be accrued for union employee participants, at which time the plan will be fully frozen. There will be a transition benefit over the next three years for active employees who have been transitioned to a new defined contribution plan. Additionally, there will be changes in the employer contribution feature of our defined contribution plan for all employees.

Our funding policy for this defined benefit retirement plan is to make annual contributions of not less than the minimum funding requirements of the Employee Retirement Income Security Act of 1974. Benefits are based on the employee’s years of service and compensation.

The net periodic pension expense consisted of the following components:



	Three Months Ended March 31,
	2012			2011
	(In thousands)

Service cost – benefit earned during the period	$	170		$	1,267

Estimated effect of curtailment	225			—
Amortization of transition obligation	3,380			—
Net periodic pension expense	$	4,316		$	1,840

The expected long-term annual rate of return on plan assets is 6.50%. This rate was used in measuring 2012 net periodic benefit costs. We expect to contribute between zero and $20 million to the retirement plan in 2012.

As a result of our merger with Frontier, we have a post-retirement healthcare and other benefits plan that is available to certain eligible employees of the El Dorado Refinery who were hired before certain defined dates and satisfy certain age and service requirements. Under this program, employees hired on or before November 16, 1999 qualify for retirement healthcare insurance until eligible for Medicare. Employees hired on or before January 1, 1995 are also eligible for Medicare supplemental insurance.

The net periodic benefit expense consisted of the following components:

NOTE 17:	Contingencies

We are a party to various litigation and proceedings which we believe, based on advice of counsel, will not either individually or in the aggregate have a materially adverse effect on our financial condition, results of operations or cash flows.


NOTE 18:	Segment Information

Our operations are organized into two reportable segments, Refining and HEP. Our operations that are not included in the Refining and HEP segments are included in Corporate and Other. Intersegment transactions are eliminated in our consolidated financial statements and are included in Consolidations and Eliminations.

The Refining segment represents the operations of the El Dorado, Tulsa, Navajo, Cheyenne and Woods Cross Refineries and NK Asphalt. Refining activities involve the purchase and refining of crude oil and wholesale and branded marketing of refined products, such as gasoline, diesel fuel and jet fuel. These petroleum products are primarily marketed in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. Additionally, the Refining segment includes specialty lubricant products produced at our Tulsa Refineries that are marketed throughout North America and are distributed in Central and South America. NK Asphalt operates various asphalt terminals in Arizona and New Mexico.

The HEP segment includes all of the operations of HEP, a consolidated VIE, which owns and operates logistic assets consisting of petroleum product and crude oil pipelines and terminal, tankage and loading rack facilities in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. Revenues are generated by charging tariffs for transporting petroleum products and crude oil through its pipelines, by leasing certain pipeline capacity to Alon USA, Inc., by charging fees for terminalling refined products and other hydrocarbons and storing and providing other services at its storage tanks and terminals. The HEP segment also includes a 25% interest in SLC Pipeline that services refineries in the Salt Lake City, Utah area. Revenues from the HEP segment are earned through transactions with unaffiliated parties for pipeline transportation, rental and terminalling operations as well as revenues relating to pipeline transportation services provided for our refining operations. Our revaluation of HEP’s assets and liabilities at March 1, 2008 (date of reconsolidation) resulted in basis adjustments to our consolidated HEP balances. Therefore, our reported amounts for the HEP segment may not agree to amounts reported in HEP’s periodic public filings.

The accounting policies for our segments are the same as those described in the summary of significant accounting policies in our Annual Report on Form 10-K for the year ended December 31, 2011.

NOTE 19:	Supplemental Guarantor/Non-Guarantor Financial Information

Our obligations under the HollyFrontier Senior Notes have been jointly and severally guaranteed by the substantial majority of our existing and future restricted subsidiaries (“Guarantor Restricted Subsidiaries”). These guarantees are full and unconditional. HEP, in which we have a 42% ownership interest, and its subsidiaries (collectively, “Non-Guarantor Non-Restricted Subsidiaries”), and certain of our other subsidiaries (“Non-Guarantor Restricted Subsidiaries”) have not guaranteed these obligations.

The following financial information presents condensed consolidating balance sheets, statements of income, and statements of cash flows of HollyFrontier Corporation (the “Parent”), the Guarantor Restricted Subsidiaries, the Non-Guarantor Restricted Subsidiaries and the Non-Guarantor Non-Restricted Subsidiaries. The information has been presented as if the Parent accounted for its ownership in the Guarantor Restricted Subsidiaries, and the Guarantor Restricted Subsidiaries accounted for the ownership of the Non-Guarantor Restricted Subsidiaries and Non-Guarantor Non-Restricted Subsidiaries, using the equity method of accounting. The Guarantor Restricted Subsidiaries and the Non-Guarantor Restricted Subsidiaries are collectively the “Restricted Subsidiaries.”

Additionally, the following financial information does not include condensed consolidating statements of comprehensive income. Our consolidated statements of comprehensive income include an other comprehensive loss of $95.7 million (net of tax) attributable to our Guarantor Restricted Subsidiaries for the three months ended March 31, 2012 and zero for the three months ended March 31, 2011. Other comprehensive income attributable to Non-Guarantor Non-Restricted Subsidiaries was $0.4 million for the three months ended March 31, 2012 and 2011.

Our revaluation of HEP’s assets and liabilities at March 1, 2008 (date of reconsolidation) resulted in basis adjustments to our consolidated HEP balances. Therefore, our reported amounts for the HEP segment may not agree to amounts reported in HEP’s periodic public filings.

Item 2.	Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Item 2 contains “forward-looking” statements. See “Forward-Looking Statements” at the beginning of Part I of this Quarterly Report on Form 10-Q. References herein to HollyFrontier Corporation (“HollyFrontier”) include HollyFrontier and its consolidated subsidiaries. In accordance with the Securities and Exchange Commission’s (“SEC”) “Plain English” guidelines, this Quarterly Report on Form 10-Q has been written in the first person. In this document, the words “we,” “our,” “ours” and “us” refer only to HollyFrontier and its consolidated subsidiaries or to HollyFrontier or an individual subsidiary and not to any other person, with certain exceptions. Generally, the words “we,” “our,” “ours” and “us” include Holly Energy Partners, L.P. (“HEP”) and its subsidiaries as consolidated subsidiaries of HollyFrontier, unless when used in disclosures or obligations between HEP and HollyFrontier or its other subsidiaries. This document contains certain disclosures of agreements that are specific to HEP and its consolidated subsidiaries and do not necessarily represent obligations of HollyFrontier. When used in descriptions of agreements and transactions, “HEP” refers to HEP and its consolidated subsidiaries.

We merged with Frontier Oil Corporation (“Frontier”) effective July 1, 2011. Accordingly, this document includes Frontier, its consolidated subsidiaries and the operations of the merged Frontier businesses effective July 1, 2011, but not prior to this date.

OVERVIEW

We are principally an independent petroleum refiner that produces high-value refined products such as gasoline, diesel fuel, jet fuel, specialty lubricant products, and specialty and modified asphalt. We own and operate refineries having a combined crude oil processing capacity of 443,000 barrels per day that serve markets throughout the Mid-Continent, Southwest and Rocky Mountain regions of the United States. Our refineries are located in El Dorado, Kansas (the “El Dorado Refinery”), Tulsa, Oklahoma (the, “Tulsa Refineries”), which comprise two production facilities, the Tulsa West and East facilities, a petroleum refinery in Artesia, New Mexico, which operates in conjunction with crude, vacuum distillation and other facilities situated 65 miles away in Lovington, New Mexico (collectively, the “Navajo Refinery”), Cheyenne, Wyoming (the, “Cheyenne Refinery”) and Woods Cross, Utah (the “Woods Cross Refinery”).

On February 21, 2011, we entered into a merger agreement providing for a “merger of equals” business combination between us and Frontier. On July 1, 2011, North Acquisition, Inc. a direct wholly-owned subsidiary of Holly merged with and into Frontier, with Frontier surviving as a wholly-owned subsidiary of Holly. Concurrent with the merger, we changed our name to HollyFrontier Corporation and changed the ticker symbol for our common stock traded on the New York Stock Exchange to “HFC.” Subsequent to the merger and following approval by the post-closing board of directors of HollyFrontier, Frontier merged with and into HollyFrontier, with HollyFrontier continuing as the surviving corporation. This merger combined the legacy Frontier refinery operations consisting of the El Dorado and Cheyenne Refineries, with Holly’s legacy refinery operations to form HollyFrontier.

In accordance with the merger agreement, we issued approximately 102.8 million shares of HollyFrontier common stock in exchange for outstanding shares of Frontier common stock to former Frontier stockholders. Based on the July 1, 2011 market closing price of $35.93, the aggregate equity consideration paid in connection with the merger was approximately $3.7 billion.

Sales and other revenues and net income attributable to HollyFrontier stockholders were $4,931.7 million and $2,326.6 million, and $241.7 million and $84.7 million for the three months ended March 31, 2012 and 2011, respectively. Our principal expenses are costs of products sold and operating expenses. Our total operating costs and expenses were $4,512.2 million and $2,167.5 million for the three months ended March 31, 2012 and 2011, respectively.

(1)

Earnings before interest, taxes, depreciation and amortization, which we refer to as "EBITDA", is calculated as net income plus (i) interest expense, net of interest income, (ii) income tax provision, and (iii) depreciation and amortization. EBITDA is not a calculation provided for under GAAP; however, the amounts included in the EBITDA calculation are derived from amounts included in our consolidated financial statements. EBITDA should not be considered as an alternative to net income or operating income as an indication of our operating performance or as an alternative to operating cash flow as a measure of liquidity. EBITDA is not necessarily comparable to similarly titled measures of other companies. EBITDA is presented here because it is a widely used financial indicator used by investors and analysts to measure performance. EBITDA is also used by our management for internal analysis and as a basis for financial covenants. EBITDA presented above is reconciled to net income under “Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles” following Item 3 of Part I of this Form 10-Q.

Our operations are organized into two reportable segments, Refining and HEP. Our operations that are not included in the Refining and HEP segment are included in Corporate and Other. Intersegment transactions are eliminated in our consolidated financial statements and are included in Eliminations.

The Refining segment includes the operations of our El Dorado, Tulsa, Navajo, Cheyenne and Woods Cross Refineries and NK Asphalt and involves the purchase and refining of crude oil and wholesale and branded marketing of refined products, such as gasoline, diesel fuel, jet fuel, specialty lubricant products, and specialty and modified asphalt. The petroleum products are primarily marketed in the Mid-Continent, Southwest and Rocky Mountain regions of the United States and northern Mexico. Additionally, specialty lubricant products produced at our Tulsa West facility are marketed throughout North America and are distributed in Central and South America. NK Asphalt manufactures and markets asphalt and asphalt products in Arizona, New Mexico, Oklahoma, Kansas, Missouri, Texas and northern Mexico.

(2)

The HEP segment involves all of the operations of HEP, which owns and operates logistic assets consisting of petroleum product and crude oil pipelines and terminal, tankage and loading rack facilities in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. Revenues are generated by charging tariffs for transporting petroleum products and crude oil through its pipelines and by charging fees for terminalling petroleum products and other hydrocarbons, and storing and providing other services at its storage tanks and terminals. Additionally, HEP owns a 25% interest in the SLC Pipeline that serves refineries in the Salt Lake City, Utah area. Revenues from the HEP segment are earned through transactions with unaffiliated parties for pipeline transportation, rental and terminalling operations as well as revenues relating to pipeline transportation services provided for our refining operations.

Results of Operations – Three Months Ended March 31, 2012 Compared to Three Months Ended March 31, 2011

Summary

Net income attributable to HollyFrontier stockholders for the three months ended March 31, 2012 was $241.7 million ($1.16 per basic and diluted share), a $157.0 million increase compared to $84.7 million ($0.79 per basic and diluted share) for the three months ended March 31, 2011. Net income increased due principally to increased operating scale following our July 1, 2011 merger, strong first quarter refining margins, as well as favorable differentials between inland and coastal-sourced crude oils. Refinery gross margins for the three months ended March 31, 2012 increased to $17.46 per produced barrel compared to $15.72 for the three months ended March 31, 2011.

Sales and Other Revenues

Sales and other revenues increased 112% from $2,326.6 million for the three months ended March 31, 2011 to $4,931.7 million for the three months ended March 31, 2012, due principally to $1,895.8 million in revenues attributable to the El Dorado and Cheyenne Refinery operations and the effects of increased refined product sales prices. The average sales price we received per produced barrel sold increased 6% from $113.28 for the three months ended March 31, 2011 to $119.54 for the three months ended March 31, 2012. Sales and other revenues for the three months ended March 31, 2012 and 2011 include $10.7 million and $10.9 million, respectively, in HEP revenues attributable to pipeline and transportation services provided to unaffiliated parties.

Cost of Products Sold

Cost of products sold increased 111% from $1,984.6 million for the three months ended March 31, 2011 to $4,186.9 million for the three months ended March 31, 2012, due principally to sales volumes attributable to the El Dorado and Cheyenne Refineries and higher crude oil costs. The average price we paid per barrel for crude oil and feedstocks and the transportation costs of moving the finished products to the market place increased 5% from $97.56 for the three months ended March 31, 2011 to $102.08 for the three months ended March 31, 2012.

Gross Refinery Margins

Gross refinery margin per produced barrel increased 11% from $15.72 for the three months ended March 31, 2011 to $17.46 for the three months ended March 31, 2012 due to the effects of an increase in the average sales price we received per barrel of produced refined products sold, partially offset by an increase in the average per barrel price we paid for crude oil and feedstocks. This was influenced by favorable differentials between inland and coastal-sourced crude oils. Gross refinery margin does not include the effects of depreciation and amortization. See “Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles” following Item 3 of Part 1 of this Form 10-Q for a reconciliation to the income statement of prices of refined products sold and cost of products purchased.

Operating Expenses

Operating expenses, exclusive of depreciation and amortization, increased 79% from $134.7 million for the three months ended March 31, 2011 to $241.6 million for the three months ended March 31, 2012, due principally to the inclusion of the El Dorado and Cheyenne Refinery operations. Also contributing to a much lesser extent were increases to our long-term environmental remediation cost estimates and increased payroll and maintenance costs attributable to the legacy Holly refining operations.

General and Administrative Expenses

General and administrative expenses increased 64% from $16.8 million for the three months ended March 31, 2011 to $27.5 million for the three months ended March 31, 2012, due principally to higher employee benefit and equity-based compensation costs and increased corporate staffing levels as a result of increased operating scale of our recently merged companies.

Depreciation and Amortization Expenses

Depreciation and amortization increased 79% from $31.3 million for the three months ended March 31, 2011 to $56.1 million for the three months ended March 31, 2012. The increase was due principally to depreciation and amortization attributable to the El Dorado and Cheyenne Refinery assets and capitalized improvement projects.

Interest Expense

Interest expense was $33.3 million for the three months ended March 31, 2012 compared to $16.2 million for the three months ended March 31, 2011. This increase reflects interest on the senior notes assumed upon our merger with Frontier. For the three months ended March 31, 2012 and 2011, interest expense included $19.2 million and $9.1 million, respectively, in interest costs attributable to HEP operations.

Table of Content

Merger Transaction Costs

For the three months ended March 31, 2011, we recognized merger transaction costs of $3.7 million related to our merger with Frontier effective July 1, 2011. These costs relate to legal, advisory and other professional fees that were directly attributable to the merger. There were no such costs incurred for the three months ended March 31, 2012.

Income Taxes

For the three months ended March 31, 2012, we recorded income tax expense of $140.4 million compared to $49.0 million for the three months ended March 31, 2011. This increase was due principally to significantly higher pre-tax earnings during the three months ended March 31, 2012 compared to the same period of 2011. Our effective tax rates, before consideration of earnings attributable to the noncontrolling interest, were 36.2% and 35.0% for the three months ended March 31, 2012 and 2011, respectively.

LIQUIDITY AND CAPITAL RESOURCES

HollyFrontier Credit Agreement

We have a $1 billion senior secured credit agreement (the “HollyFrontier Credit Agreement”) with Union Bank, N.A. as administrative agent and BNP Paribas as syndication agent, and certain lenders from time to time thereto. The HollyFrontier Credit Agreement matures in July 2016 and may be used to fund working capital requirements, capital expenditures, acquisitions and general corporate purposes. Obligations under the HollyFrontier Credit Agreement are collateralized by our inventory, accounts receivables and certain deposit accounts and guaranteed by our material, wholly-owned subsidiaries.

HEP Credit Agreement

HEP has a $375 million senior secured revolving credit facility (the “HEP Credit Agreement”), with an outstanding balance of $155.0 million at March 31, 2012, that is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. In February 2012, HEP amended its previous credit agreement increasing the size of the credit facility from $275 million to $375 million. The HEP Credit Agreement expires in February 2016.

HollyFrontier Senior Notes

Our senior notes consist of the following:


•	9.875% Senior Notes ($291.8 million principal amount maturing June 2017)


•	6.875% Senior Notes ($150 million principal amount maturing November 2018)


•	8.5% Senior Notes ($200 million principal amount maturing September 2016)

These senior notes (collectively the “HollyFrontier Senior Notes”) are unsecured and impose certain restrictive covenants, including limitations on our ability to incur additional debt, incur liens, enter into sale-and-leaseback transactions, pay dividends, enter into mergers, sell assets and enter into certain transactions with affiliates. At any time when the HollyFrontier Senior Notes are rated investment grade by both Moody’s and Standard & Poor’s and no default or event of default exists, we will not be subject to many of the foregoing covenants. Additionally, we have certain redemption rights under the HollyFrontier Senior Notes.

HollyFrontier Financing Obligation

In October 2009, we sold approximately 400,000 barrels of crude oil tankage at our Tulsa West facility as well as certain crude oil pipeline receiving facilities to an affiliate of Plains All American Pipeline, L.P. (“Plains”) for $40 million in cash. In connection with this transaction, we entered into a 15-year lease agreement with Plains, whereby we agreed to pay a fixed monthly fee for the exclusive use of this tankage as well as a fee for volumes received at the receiving facilities purchased by Plains. Additionally, we have a margin sharing agreement with Plains under which we will equally share contango profits with Plains for crude oil purchased by them and delivered to our Tulsa West facility for storage. Due to our continuing involvement in these assets, this sales and lease transaction has been accounted for as a financing obligation. As a result, we retained these assets on our books and recorded a liability representing the $40 million in proceeds received.

HEP Senior Notes

HEP’s senior notes consist of the following:


•	6.25% Senior Notes ($27.3 million principal amount outstanding at March 31, 2012 and redeemed in April 2012)


•	6.5% Senior Notes ($300 million principal amount maturing March 2020)


•	8.25% Senior Notes ($150 million principal amount maturing March 2018)

In March 2012, HEP issued $300 million in aggregate principal amount of 6.5% HEP senior notes maturing March 2020. The $294.8 million in net proceeds were used to fund $157.8 million aggregate principal amount of 6.25% senior notes tendered pursuant to a cash tender offer and consent solicitation announced in February 2012, to repay $72.9 million in promissory notes due to HollyFrontier, related fees, expenses and accrued interest in connection with these transactions and to repay borrowings under the HEP Credit Agreement. In April 2012, HEP called for redemption $27.2 million aggregate principal amount of 6.25% Senior Notes that remained outstanding following the cash tender offer and consent solicitation.

The HEP 6.5% senior notes and 8.25% senior notes (collectively, the “HEP Senior Notes”) are unsecured and impose certain restrictive covenants, including limitations on HEP’s ability to incur additional indebtedness, make investments, sell assets, incur certain liens, pay distributions, enter into transactions with affiliates, and enter into mergers. At any time when the HEP Senior Notes are rated investment grade by both Moody’s and Standard & Poor’s and no default or event of default exists, HEP will not be subject to many of the foregoing covenants. Additionally, HEP has certain redemption rights under the HEP Senior Notes.

See “Risk Management” for a discussion of HEP’s interest rate swap contracts.

Liquidity

We believe our current cash and cash equivalents, along with future internally generated cash flow and funds available under our credit facilities will provide sufficient resources to fund currently planned capital projects and our liquidity needs for the foreseeable future. In addition, components of our growth strategy include construction of new refinery processing units and the expansion of existing units at our facilities and selective acquisition of complementary assets for our refining operations intended to increase earnings and cash flow. Our ability to acquire complementary assets will be dependent upon several factors, including our ability to identify attractive acquisition candidates, consummate acquisitions on favorable terms, successfully integrate acquired assets and obtain financing to fund acquisitions and to support our growth, and many other factors beyond our control.

As of March 31, 2012, our cash, cash equivalents and investments in marketable securities totaled $1.9 billion. We consider all highly-liquid instruments with a maturity of three months or less at the time of purchase to be cash equivalents. Cash equivalents are stated at cost, which approximates market value, and are invested primarily in conservative, highly-rated instruments issued by financial institutions or government entities with strong credit standings.

Cash and cash equivalents increased by $80.6 million for the three months ended March 31, 2012. Net cash provided by operating activities of $253.9 million exceeded cash used for investing and financing activities of $68.7 million and $104.6 million, respectively. Working capital decreased by $20.8 million during the three months ended March 31, 2012.

Cash Flows – Operating Activities

expense and derivative instrument adjustments resulted in an increase to operating cash flows of $75.2 million for the three months ended March 31, 2012 compared to $33.7 million for the same period in 2011. Changes in working capital items decreased cash flows by $67.5 million for the three months ended March 31, 2012 compared to an increase of $18.9 million for the three months ended March 31, 2011. Additionally, for the three months ended March 31, 2012, turnaround expenditures increased to $21.8 million from $16.9 million for the same period of 2011 .

Cash Flows – Investing Activities and Planned Capital Expenditures

Three Months Ended March 31, 2012 Compared to Three Months Ended March 31, 2011

Net cash flows used for investing activities were $68.7 million for the three months ended March 31, 2012 compared to $141.1 million for the three months ended March 31, 2011, a decrease of $72.4 million. Cash expenditures for properties, plants and equipment for the first three months of 2012 decreased to $61.4 million from $74.0 million for the same period in 2011. These include HEP capital expenditures of $6.3 million and $11.5 million for the three months ended March 31, 2012 and 2011, respectively. Also for the three months ended March 31, 2012 and 2011, we invested $106.6 million and $98.9 million, respectively, in marketable securities and received proceeds of $100.5 million and $31.9 million, respectively, from the sale or maturity of marketable securities.

Planned Capital Expenditures

HollyFrontier Corporation

Each year our Board of Directors approves our annual capital budget which includes specific projects that our management is authorized to undertake. Additionally, when conditions warrant or as new opportunities arise, additional projects may be approved. The funds appropriated for a particular capital project may be expended over a period of several years, depending on the time required to complete the project. Therefore, our planned capital expenditures for a given year consist of expenditures appropriated in that year’s capital budget plus expenditures for projects appropriated in prior years which have not yet been completed. Our appropriated capital budget for 2012 is $257.0 million including both sustaining capital and major capital projects. We expect to spend approximately $350.0 million in cash for capital projects in 2012, including projects approved in prior years, and is comprised of $101.0 million at the Tulsa Refineries, $85.0 million at the Woods Cross Refinery, $55.0 million at the El Dorado Refinery, $46.0 million at the Cheyenne Refinery, $38.0 million at the Navajo Refinery, $16.0 million for our portion of the UNEV Pipeline and $9.0 million for miscellaneous projects. In addition, we expect to spend $120.0 million on refinery turnarounds and tank maintenance.

A significant portion of our current capital spending is associated with compliance-oriented capital improvements. This spending is required due to existing consent decrees (for projects including FCC unit flue gas scrubbers and tail gas treatment units), federal fuels regulations (particularly, MSAT2 which mandates a reduction in the benzene content of blended gasoline), refinery waste water treatment improvements and other similar initiatives. Our refinery operations and related emissions are highly regulated at both federal and state levels, and we invest in our facilities as needed to remain in compliance with these standards. Additionally, when faced with new emissions or fuels standards, we seek to execute projects that facilitate compliance and also improve the operating costs and/or yields of associated refining processes.

El Dorado Refinery

Newly appropriated capital projects at the El Dorado Refinery include naphtha splitting and aromatics recovery unit revamps to reduce benzene in gasoline (MSAT2 compliance) and installation of a new tail gas treatment unit with our sulfur recovery facilities as required under an existing EPA consent decree. Also included in the 2012 capital budget are yield improvement projects that address both the FCC unit and the Coker. A previously appropriated project which we expect to complete during 2012 is the replacement of an existing Coker furnace with more current furnace technology. This project is expected to improve Coker on-stream factor and reduce fuel consumption. We expect to complete this project in late 2012.

Tulsa Refineries

The most significant newly appropriated capital project for our Tulsa Refineries is conversion of a propane de-asphalt unit to ROSE technology. This project is expected to cost $25.0 million and will increase processing of vacuum tower bottoms, increase the production of bright stock lube, reduce energy consumption, and allow the shutdown of a low-pressure steam boiler. Projects still underway from prior appropriations include a $58.0 million project to recover sulfur from the refinery fuel gas system and to shut down another low-pressure steam boiler by electrification of turbine drivers. The sulfur recovery project is required to comply with our EPA consent decree but is being enhanced so as to increase our capacity to run lower priced sour / heavy crude in Tulsa. We are also executing an an approved LPG recovery project in Tulsa at an estimated total cost of $28.0 million. This project will improve overall liquid yields and enable us to substitute lower-priced natural gas for LPG's currently being consumed as refinery fuel. Other projects underway in Tulsa involve replacement of an existing vacuum tower and improvements to our wastewater treatment plants and storm water retention systems.

Table of Content

Navajo Refinery

We have approved a new project for the Navajo Refinery to remove sulfur and other contaminants from the crude unit off-gas stream that will improve liquid yields and reduce refinery fuel costs. Current spending on previously appropriated projects includes an MSAT2 project (naphtha splitting benzene saturation) to reduce reliance on benzene credits purchases, as well as expenditures to improve the Artesia waste water handling and processing facilities.

Cheyenne Refinery

We have approved four new compliance projects for the Cheyenne Refinery including wastewater treatment plant improvements, a wet gas scrubber for the FCC unit to reduce particulate and other emissions, MSAT2 related investments to reduced benzene in gasoline, and spending for additional tail gas unit associated with our sulfur recovery facilities. We also plan to improve metallurgy on portions of the Cheyenne Refinery’s delayed coking unit. These new major capital appropriations total approximately $60 million, and we expect to spend approximately 30% of this amount on these projects during 2012. Expenditures for MSAT2 compliance projects were accelerated by approximately one year at each of the Cheyenne and El Dorado Refineries due to the Holly-Frontier merger, which resulted in our loss of a small refiner exemption that previously provided for delayed compliance with this standard.

Woods Cross Refinery

We plan to significantly expand our Woods Cross Refinery in response to increased availability of locally-produced black wax crude oil. We have announced a 10-year crude supply agreement with Newfield Exploration Company under which we will purchase 20,000 BPD of waxy crudes (black and yellow wax). Our expansion project will increase crude processing capacity of Woods Cross from 31,000 BPD to 45,000 BPD. Most of the incremental crude supply is expected to be waxy crude, and the expansion is being configured to create high liquid yields and relatively large proportions of additional gasoline and diesel fuel in comparison to the increased crude charge. We expect this $225.0 million project to have a pre-tax payback period of approximately two years, and we expect to complete the expansion in approximately the fourth quarter of 2014. Our execution of this project is subject to certain contingencies, including our receipt of required emissions and other permits. Also at Woods Cross, we have two significant compliance projects authorized in prior year appropriations. The first of these involves installation of a wet gas scrubber on the FCC unit to reduce particulate and other emissions and the second relates to MSAT2 compliance which will require naphtha fractionation and benzene saturation.

UNEV

The UNEV Pipeline and associated product terminals in Cedar City, Utah and Las Vegas, Nevada were operational during the first quarter of 2012. Our estimate of total installed cost is $308.0 million for our 75% equity interest in this pipeline.

Regulatory compliance items or other presently existing or future environmental regulations / consent decrees could cause us to make additional capital investments beyond those described above and incur additional operating costs to meet applicable requirements.

HEP

Each year the Holly Logistic Services, L.L.C. board of directors approves HEP’s annual capital budget, which specifies capital projects that HEP management is authorized to undertake. Additionally, at times when conditions warrant or as new opportunities arise, special projects may be approved. The funds allocated for a particular capital project may be expended over a period of several years, depending on the time required to complete the project. Therefore, HEP’s planned capital expenditures for a given year consist of expenditures approved for capital projects included in its current year capital budget as well as, in certain cases, expenditures approved for capital projects in capital budgets for prior years. The 2012 HEP capital budget is comprised of $8.9 million for maintenance capital expenditures and $25.8 million for expansion capital expenditures.

HEP has recently made certain modifications to its crude oil gathering and trunk line system that have effectively increased HEP’s ability to gather and transport an additional 10,000 bpd of Delaware Basin crude oil in response to increased drilling activity in southeast New Mexico. Furthermore, HEP has developed a project to replace a 5-mile section of this pipeline system that will allow for an additional 15,000 bpd of capacity that will be executed as needed if Delaware Basin crude volumes continue to increase. This project is estimated to cost approximately $2.0 million. HEP has a second project which consists of the reactivation and conversion to crude oil service of a 70-mile, 8-inch petroleum products pipeline owned by HEP. Once in service, this pipeline will initially be capable of transporting up to 35,000 bpd of crude oil from southeast New Mexico to third-party common carrier pipelines in west Texas for further transport to major crude oil markets. The scope of this project is being finalized. Subject to receipt of acceptable shipper support and board approval, this project could be operational in early 2013.

Cash Flows – Financing Activities

Three Months Ended March 31, 2012 Compared to Three Months Ended March 31, 2011

Net cash flows used for financing activities were $104.6 million for the three months ended March 31, 2012 compared to net cash flows provided by financing activities of $5.5 million for the three months ended March 31, 2011, a decrease of $110.1 million. During the three months ended March 31, 2012, we purchased $62.5 million in common stock, paid $126.0 million in dividends, received a $5.5 million contribution from our UNEV Pipeline joint venture partner and recognized $3.8 million excess tax benefits on our equity-based compensation. Also during this period, HEP received $294.8 million in net proceeds upon the issuance of the HEP 6.5% senior notes, paid $157.8 million in principal on the HEP 6.25% senior notes, received $36.0 million and repaid $81.0 million under the HEP Credit Agreement, paid distributions of $14.4 million to noncontrolling interests, incurred $1.1 million in deferred financing costs and purchased $1.3 million in HEP common units in the open market for recipients of its incentive grants. During the three months ended March 31, 2011, we purchased $2.1 million in common stock, paid $8.0 million in dividends, received an $8.5 million contribution from our UNEV Pipeline joint venture partner and recognized $0.3 million excess tax benefits on our equity-based compensation. Also during this period, HEP received $30.0 million and repaid $7.0 million under the HEP Credit Agreement, paid distributions of $12.5 million to noncontrolling interests, incurred $3.0 million in deferred financing costs and purchased $0.4 million in HEP common units in the open market for recipients of its incentive grants.

Contractual Obligations and Commitments

HollyFrontier Corporation

There were no significant changes to our contractual obligations during the three months ended March 31, 2012.

HEP

In February 2012, HEP amended its previous credit agreement increasing the size of the credit facility from $275 million to $375 million. The HEP Credit Agreement expires in February 2016. During the three months ended March 31, 2012, HEP repaid net advances of $45.0 million resulting in $155.0 million of outstanding borrowings under the HEP Credit Agreement at March 31, 2012.

In March 2012, HEP issued $300 million in aggregate principal amount of 6.5% senior notes maturing March 2020.

There were no other significant changes to HEP’s long-term contractual obligations during this period.

CRITICAL ACCOUNTING POLICIES

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities as of the date of the financial statements. Actual results may differ from these estimates under different assumptions or conditions.

Our significant accounting policies are described in “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies” in our Annual Report on Form 10-K for the year ended December 31, 2011. Certain critical accounting policies that materially affect the amounts recorded in our consolidated financial statements include the assessment and consolidation of variable interest entities, the use of the LIFO method of valuing certain inventories, the amortization of deferred costs for regular major maintenance and repairs at our refineries, assessing the possible impairment of certain long-lived assets and goodwill, accounting for derivative instruments and assessing contingent liabilities for probable losses.

At March 31, 2012, we changed our policy of reporting certain same-party accounts receivable and payable amounts in the consolidated balance sheets to reflect a net amount due under contractual netting agreements. Prior to this change, we reported such amounts on a gross basis with a same-party receivable and payable balance presented separately in our balance sheet. GAAP permits a reporting entity to elect a policy of offsetting same party receivables and payables when such amounts are net settled under legally enforceable contractual setoff provisions. We believe that a net presentation is preferable because it more appropriately presents our economic resources (accounts receivable) and claims against us (accounts payable) and the future cash flows associated with such assets and liabilities. Additionally, we believe a net presentation of such amounts will conform to the predominant practices used by others in our industry. We have applied this change in accounting principle on a retrospective basis and have recast our prior period financial statements. See Note 2 to our Consolidated Financial Statements under Item 8 for a summary of line items affected in our prior period financial statements.

Table of Content

We use the LIFO method of valuing inventory. Under the LIFO method, an actual valuation of inventory can only be made at the end of each year based on the inventory levels. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and are subject to the final year-end LIFO inventory valuation.

Goodwill represents the excess of the cost of an acquired entity over the fair value of the assets acquired and liabilities assumed. Goodwill is not subject to amortization and is tested annually or more frequently if events or circumstances indicate the possibility of impairment. As of March 31, 2012, there have been no impairments to goodwill.

New Accounting Pronouncements

Presentation of Comprehensive Income

Intangibles — Goodwill and Other: Testing Goodwill for Impairment

Effective January 1, 2012, we adopted the accounting standard update that allows entities an option to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under this option, we no longer are required to calculate the fair value of a reporting unit unless we determine, based on that qualitative assessment, that it is more likely than not that the reporting unit’s fair value is less than its carrying amount. The adoption of this accounting standard did not have an impact on our financial condition, results of operations and cash flows.

RISK MANAGEMENT

We use certain strategies to reduce some commodity price and operational risks. We do not attempt to eliminate all market risk exposures when we believe that the exposure relating to such risk would not be significant to our future earnings, financial position, capital resources or liquidity or that the cost of eliminating the exposure would outweigh the benefit.

Commodity Price Risk Management

We periodically enter into derivative contracts in the form of commodity price swaps to mitigate price exposure with respect to:


•	our inventory positions;


•	natural gas purchases;


•	costs of crude oil;


•	prices of refined products; and


•	our refining margins.

We have swap contracts that fix our purchase price on forecasted natural gas purchases (8,800,000 MMBTUs through 2012). Also, we have swap contracts that lock in the spread between WCS and WTI crude oil on forecasted purchases (5,970,000 barrels of crude oil through the end of 2013) and NYMEX futures contracts to lock in prices on forecasted sales and purchases of inventory (2,913,000 barrels and 409,000 barrels, respectively, through 2013).

Interest Rate Risk Management

HEP uses interest rate swaps to manage its exposure to interest rate risk.

Table of Content

Publicly available information is reviewed on the counterparties in order to review and monitor their financial stability and assess their ongoing ability to honor their commitments under the swap contracts. These counterparties are large financial institutions. We have not experienced, nor do we expect to experience, any difficulty in the counterparties honoring their commitments.

The market risk inherent in our fixed-rate debt and positions is the potential change arising from increases or decreases in interest rates as discussed below.

For the fixed rate HollyFrontier Senior Notes and HEP Senior Notes, changes in interest rates will generally affect fair value of the debt, but not our earnings or cash flows. The outstanding principal, estimated fair value and estimated change in fair value (assuming a hypothetical 10% change in the yield-to-maturity rates) for these debt instruments as of March 31, 2012 is presented below:



	Outstanding Principal		Estimated Fair Value		Estimated Change in Fair Value
	(In thousands)
HollyFrontier Senior Notes	$	641,797	$	699,834	$	19,725
HEP Senior Notes	$	477,254	$	494,062	$	16,762

For the variable rate HEP Credit Agreement, changes in interest rates would affect cash flows, but not the fair value. At March 31, 2012, outstanding borrowings under the HEP Credit Agreement were $155.0 million. By means of its cash flow hedge, HEP has effectively converted the variable rate on $155.0 million of outstanding principal to a fixed rate of 3.24%.

At March 31, 2012, cash and cash equivalents included investments in investment grade, highly liquid investments with maturities of three months or less at the time of purchase and hence the interest rate market risk implicit in these cash investments is low. Due to the short-term nature of our cash and cash equivalents, a hypothetical 10% increase in interest rates would not have a material effect on the fair market value of our portfolio. Since we have the ability to liquidate this portfolio, we do not expect our operating results or cash flows to be materially affected by the effect of a sudden change in market interest rates on our investment portfolio.

Our operations are subject to normal hazards of operations, including fire, explosion and weather-related perils. We maintain various insurance coverages, including business interruption insurance, subject to certain deductibles. We are not fully insured against certain risks because such risks are not fully insurable, coverage is unavailable, or premium costs, in our judgment, do not justify such expenditures.

We have a risk management oversight committee that is made up of members from our senior management. This committee oversees our risk enterprise program, monitors our risk environment and provides direction for activities to mitigate identified risks that may adversely affect the achievement of our goals.

Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles

Reconciliations of earnings before interest, taxes, depreciation and amortization (“EBITDA”) to amounts reported under generally accepted accounting principles in financial statements.

Earnings before interest, taxes, depreciation and amortization, which we refer to as EBITDA, is calculated as net income attributable to HollyFrontier stockholders plus (i) interest expense, net of interest income, (ii) income tax provision, and (iii) depreciation and amortization. EBITDA is not a calculation provided for under GAAP; however, the amounts included in the EBITDA calculation are derived from amounts included in our consolidated financial statements. EBITDA should not be considered as an alternative to net income or operating income as an indication of our operating performance or as an alternative to operating cash flow as a measure of liquidity. EBITDA is not necessarily comparable to similarly titled measures of other companies. EBITDA is presented here because it is a widely used financial indicator used by investors and analysts to measure performance. EBITDA is also used by our management for internal analysis and as a basis for financial covenants.

Reconciliations of refinery operating information (non-GAAP performance measures) to amounts reported under generally accepted accounting principles in financial statements.

Refinery gross margin and net operating margin are non-GAAP performance measures that are used by our management and others to compare our refining performance to that of other companies in our industry. We believe these margin measures are helpful to investors in evaluating our refining performance on a relative and absolute basis.

Refinery gross margin per barrel is the difference between average net sales price and average cost of products per barrel of produced refined products. Net operating margin per barrel is the difference between refinery gross margin and refinery operating expenses per barrel of produced refined products. These two margins do not include the effect of depreciation and amortization. Each of these component performance measures can be reconciled directly to our consolidated statements of income.

Other companies in our industry may not calculate these performance measures in the same manner.

Refinery Gross and Net Operating Margins

Below are reconciliations to our consolidated statements of income for (i) net sales, cost of products and operating expenses, in each case averaged per produced barrel sold, and (ii) net operating margin and refinery gross margin. Due to rounding of reported numbers, some amounts may not calculate exactly.

PART II. OTHER INFORMATION


Item 1.	Legal Proceedings

Commitment and Contingency Reserves

We periodically establish reserves for certain legal proceedings. The establishment of a reserve involves an estimation process that includes the advice of legal counsel and subjective judgment of management. While management believes these reserves to be adequate, future changes in the facts and circumstances could result in the actual liability exceeding the estimated ranges of loss and amounts accrued.

While the outcome and impact on us cannot be predicted with certainty, management believes that the resolution of these proceedings through settlement or adverse judgment will not have a material adverse effect on our consolidated financial position or cash flow. Operating results, however, could be significantly impacted in the reporting periods in which such matters are resolved.

New Mexico OHSB Complaint – Navajo Tank Fire

On March 3, 2010, the New Mexico Occupational Health and Safety Bureau (“OHSB”), the New Mexico regulatory agency responsible for enforcing certain state occupational health and safety regulations, which are identical to Federal Occupational Safety and Health Administration (“OSHA”) regulations, commenced an inspection in relation to the tank fire that took place on March 2, 2010 at the Navajo facility in Artesia, New Mexico. On August 31, 2010, OHSB issued two citations to Navajo, alleging 10 willful violations and one serious violation of various construction safety standards. OHSB proposed penalties in the amount of $0.7 million. Navajo filed a notice of contest, challenging the citations. The parties commenced settlement negotiations but were unable to reach an agreement, thus OHSB filled an administrative complaint with New Mexico Occupational Health and Safety Review Commission (“OHSRC”) on December 20, 2010. Discovery is under way at this time. The parties are scheduled to meet to continue settlement discussions on May 9-10, 2012. Should the parties be unable to reach agreement, the hearing in this matter will be scheduled to commence no sooner than January 2013.

Propane Pit - Woods Cross

In December 2011, representatives of EPA Region 8 conducted an inspection of the Woods Cross refinery in Utah (“Woods Cross”). The purpose of the inspection was to determine compliance with the Chemical Accident Prevention and Risk Management Plan (“RMP”) requirements set forth in section 112(r)(7) of the Federal Clean Air Act and Part 68 of Title 40 of the Code of Federal Regulations. On January 31, 2012, EPA sent a letter to Woods Cross indicating it identified some potential violations of the RMP requirements. On February 28, 2012, representatives of Woods Cross and EPA had an initial meeting and preliminary discussion about the RMP issues EPA had identified. Prior to this meeting, in 2009 and 2010, Woods Cross voluntarily reported to EPA and the Utah Department of Environmental Quality possible regulatory issues associated with the Frozen Earth Storage propane pit (“FES”) at Woods Cross and was working to resolve them. In addition, prior to the meeting, Woods Cross had made a decision to decommission the FES. Woods Cross representatives communicated this decision to EPA at the February meeting. On April 17, 2012, EPA sent to Woods Cross a draft Administrative Order on Consent and a draft Consent Agreement under which Woods Cross would decommission the FES and pay a civil penalty of $159,200 for alleged RMP program violations-a number of which are unrelated to the FES. Woods Cross does not agree with EPA’s proposed penalty and the allegations of violations. Woods Cross intends to respond to the allegations and work cooperatively with EPA to address its concerns and contentions relating to the amount of the penalty and the legitimacy of a number of the alleged violations. At this early stage of the proceedings, it is impossible to accurately predict the outcome of this matter.

Other

We are a party to various other litigation and proceedings that we believe, based on advice of counsel, will not either individually or in the aggregate have a materially adverse impact on our financial condition, results of operations or cash flows.

These withholdings were made under the terms of our share-based compensation unit agreements to provide funds for the payment of payroll and income taxes due at vesting in the case of officers and employees who did not elect to satisfy such taxes by other means.
