Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description Of Business And Presentation Of Financial Statements	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 of transactions 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 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 June 30, 2016 , 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 HollyFrontier Asphalt Company LLC (“HFC Asphalt”) which operates various asphalt terminals in Arizona, New Mexico and Oklahoma; and • owned a 39% interest in HEP, a consolidated variable interest entity (“VIE”), which includes our 2% general partner interest. 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 June 30, 2016 , the consolidated results of operations and comprehensive income for the three and six months ended June 30, 2016 and 2015 and consolidated cash flows for the six months ended June 30, 2016 and 2015 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, 2015 that has been filed with the SEC. Our results of operations for the six months ended June 30, 2016 are not necessarily indicative of the results of operations to be realized for the year ending December 31, 2016 . Accounts Receivable: Our accounts receivable consist of amounts due from customers that are primarily companies in the petroleum industry. 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 $2.3 million at both June 30, 2016 and December 31, 2015 . Inventories: Inventories are stated at the lower of cost, using the last-in, first-out (“LIFO”) method for crude oil, unfinished and finished refined products and the average cost method for materials and supplies, or market. In periods of rapidly declining prices, LIFO inventories may have to be written down to market value due to the higher costs assigned to LIFO layers in prior periods. In addition, the use of the LIFO inventory method may result in increases or decreases to cost of sales in years that inventory volumes decline as the result of charging cost of sales with LIFO inventory costs generated in prior periods. An actual valuation of inventory under the LIFO method is 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 and Long-lived Assets: As of December 31, 2015 and March 31, 2016, our goodwill balance was $2.3 billion , with $1.7 billion , $0.3 billion and $0.3 billion allocated to our El Dorado Refinery, Cheyenne Refinery and HEP reporting units, respectively. 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 an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Our goodwill impairment testing first entails a comparison of our reporting unit fair values relative to their respective carrying values. If carrying value exceeds fair value for a reporting unit, we measure goodwill impairment as the excess of the carrying amount of reporting unit goodwill over the implied fair value of that goodwill based on estimates of the fair value of all assets and liabilities in the reporting unit. Prior to the second quarter of 2016, there had been no impairments to goodwill. Our long-lived assets principally consist of our refining assets that are organized as refining asset groups. These refinery asset groups also constitute our individual refinery reporting units that are used for testing and measuring goodwill impairments (El Dorado and Cheyenne). Our long-lived assets are evaluated for impairment by identifying whether indicators of impairment exist and if so, assessing whether the long-lived assets are recoverable from estimated future undiscounted cash flows. The actual amount of impairment loss measured, if any, is equal to the amount by which the asset group’s carrying value exceeds its fair value. Goodwill and long-lived asset impairments During the second quarter of 2016, we performed interim goodwill impairment testing of our El Dorado and Cheyenne Refinery reporting units after identifying a combination of events and circumstances which were indicators of potential goodwill impairment, including lower than typical gross margins during the summer driving season, a current outlook of lower future gross margins, and the recent decline in our common share price which has resulted in a decrease in our market capitalization. In conjunction with our interim goodwill impairment testing performed, we first assessed the carrying values of our refining long-lived asset groups for recoverability. Our interim goodwill impairment and related long-lived asset impairment testing was performed as of April 30, 2016. The estimated fair values of our goodwill reporting units and long-lived asset groups were derived using a combination of both income and market approaches. The income approach reflects expected future cash flows based on estimates of future crack spreads, forecasted production levels, operating costs and capital expenditures. Our market approaches include both the guideline public company and guideline transaction methods. Both methods utilize pricing multiples derived from historical market transactions of other like-kind assets. These fair value measurements involve significant unobservable inputs (Level 3 inputs). See Note 3 for further discussion of Level 3 inputs. As a result of our impairment testing, we determined that the carrying value of the long-lived assets of the Cheyenne Refinery had been impaired and recorded long-lived asset impairment charges of $344.8 million . Additionally, the carrying value of the Cheyenne Refinery’s goodwill was fully impaired and a goodwill impairment charge of $309.3 million was also recorded. Our testing did not identify any other impairment; however, the fair value of our El Dorado reporting unit currently exceeds its carrying value by approximately 15%. A reasonable expectation exists that further deterioration in gross margins could result in an impairment of goodwill and the long-lived assets of the El Dorado reporting unit at some point in the future. Such impairment charges could be material. Income Taxes : Provisions for income taxes include deferred taxes resulting from temporary differences in income for financial and tax purposes, using the liability method of accounting for income taxes. The liability method requires the effect of tax rate changes on deferred income taxes to be reflected in the period in which the rate change was enacted. The liability method also requires that deferred tax assets be reduced by a valuation allowance unless it is more likely than not that the assets will be realized. For the six months ended June 30, 2016 , we recorded an income tax benefit of $15.7 million compared to expense of $336.7 million for the six months ended June 30, 2015 . This decrease was due principally to a pre-tax loss during the six months ended June 30, 2016 compared to pre-tax earnings in the same period of 2015 . Our effective tax rates, before consideration of earnings attributable to the noncontrolling interest, were 4.3% and 35.3% for the six months ended June 30, 2016 and 2015 , respectively. The year-over-year decrease in the effective tax rate is due principally to the effects of the second quarter $309.3 million goodwill impairment charge, a significant driver of our $364.8 million loss before income taxes for the six months ended June 30, 2016 , that is not deductible for income tax purposes. Inventory Repurchase Obligations: We periodically enter into same-party sell / buy transactions, whereby we sell certain refined product inventory and subsequently repurchase the inventory in order to facilitate delivery to certain locations. Such sell / buy transactions are accounted as inventory repurchase obligations under which proceeds received under the initial sell is recognized as an inventory repurchase obligation that is subsequently reversed when the inventory is repurchased. For the six months ended June 30, 2016 and 2015 , we received proceeds of $29.8 million and $50.0 million , respectively, and repaid $30.2 million and $51.0 million , respectively, under these sell / buy transactions. New Accounting Pronouncements Leases In February 2016, Accounting Standard Update (“ASU”) 2016-02, “Leases,” was issued requiring leases to be measured and recognized as a lease liability, with a corresponding right-of-use asset on the balance sheet. This standard has an effective date of January 1, 2019, and we are evaluating the impact of this standard. Consolidation In February 2015, ASU 2015-02, “Consolidation,” was issued to improve consolidation guidance for certain legal entities. It modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, affects the consolidation analysis of reporting entities involved with VIEs, particularly those that have fee arrangements and related party provisions and provides a scope exception from consolidation guidance for certain reporting entities that comply with or operate in accordance with requirements that are similar to those included in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. We adopted this standard effective January 1, 2016, which did not affect our financial position or results of operations. Revenue Recognition In May 2014, ASU 2014-09, “Revenue from Contracts with Customers,” was issued requiring revenue to be recognized when promised goods or services are transferred to customers in an amount that reflects the expected consideration for these goods or services. This standard has an effective date of January 1, 2018, and we are evaluating the impact of this standard.

Holly Energy Partners [Abstract]
Holly Energy Partners	HEP, a consolidated VIE, is a publicly held master limited partnership that owns and operates logistic assets consisting of petroleum product and crude oil pipelines, terminals, tankage, loading rack facilities and refinery processing units 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 75% interest in UNEV Pipeline, LLC (“UNEV”), the owner of a pipeline running from Woods Cross, Utah to Las Vegas, Nevada (the “UNEV Pipeline”) and associated product terminals; a 50% interest in Frontier Aspen LLC, the owner of a pipeline running from Wyoming to Frontier Station, Utah (the “Frontier Pipeline”); a 50% interest in Osage Pipe Line Company, LLC, the owner of a pipeline running from Cushing, Oklahoma to El Dorado, Kansas (the “Osage Pipeline”); a 50% interest in Cheyenne Pipeline, LLC, the owner of a pipeline running from Fort Laramie, Wyoming to Cheyenne, Wyoming (the “Cheyenne Pipeline”); and a 25% interest in SLC Pipeline LLC, the owner of a pipeline (the “SLC Pipeline”) that serves refineries in the Salt Lake City, Utah area. As of June 30, 2016 , we owned a 39% interest in HEP, including the 2% general partner interest. As the general partner of HEP, we have the sole ability to direct the activities that most significantly impact HEP’s financial performance, and therefore we consolidate HEP. HEP has two primary customers (including us) and generates revenues by charging tariffs for transporting petroleum products and crude oil through 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 82% of HEP’s total revenues for the six months ended June 30, 2016 . We do not provide financial or equity support through any liquidity arrangements and / or debt guarantees to HEP. HEP has outstanding debt under a senior secured revolving credit agreement and its senior notes. HEP’s creditors have no recourse to our assets. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries. See Note 9 for a description of HEP’s debt obligations. HEP has risk associated with its operations. If a major customer 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. Cheyenne Pipeline On June 3, 2016, HEP acquired a 50% interest in Cheyenne Pipeline LLC, owner of the Cheyenne Pipeline, in exchange for a contribution of $42.5 million in cash to Cheyenne Pipeline LLC. Cheyenne Pipeline will continue to be operated by an affiliate of Plains All American Pipeline, L.P. (“Plains”), which owns the remaining 50% interest. The 87-mile crude oil pipeline runs from Fort Laramie, Wyoming to Cheyenne, Wyoming and has an 80,000 BPD capacity. Tulsa Tanks On March 31, 2016, HEP acquired crude oil tanks located at our Tulsa Refineries from Plains for $39.5 million . Previously in 2009, we sold these tanks to Plains and leased them back, and due to our continuing interest in the tanks, we accounted for the transaction as a financing arrangement. Accordingly, the tanks remained on our balance sheet and were depreciated for accounting purposes, and the proceeds received from Plains were recorded as a financing obligation and presented as a component of outstanding debt. In accounting for HEP’s March 2016 purchase from Plains, the amount paid was recorded against our outstanding financing obligation balance of $30.8 million , with the excess $8.7 million payment resulting in a loss on early extinguishment of debt. Magellan Asset Exchange On February 22, 2016, we acquired a 50% membership interest in Osage Pipe Line Company, LLC (“Osage”) in exchange for a 20-year terminalling services agreement, whereby a subsidiary of Magellan Midstream Partners (“Magellan Midstream”) will provide terminalling services for all of our products originating in Artesia, New Mexico that require terminalling in or through El Paso, Texas. Under the agreement, we will be charged tariffs based on the volumes of refined product processed. Osage is the owner of the Osage Pipeline, a 135 -mile pipeline that transports crude oil from Cushing, Oklahoma to our El Dorado Refinery in Kansas and also has a connection to the Jayhawk pipeline that services the CHS refinery in McPherson, Kansas. This exchange was accounted for at fair value, whereby the 50% membership interest in the Osage Pipeline was recorded at appraised fair value and an offsetting residual deferred credit in the amount of $38.9 million was recorded, which will be amortized over the 20-year service period. No gain or loss was recorded for this exchange. Also on February 22, 2016, we contributed the 50% membership interest in Osage to HEP, and in exchange received HEP’s El Paso terminal. Pursuant to this exchange, HEP agreed to build two connections to Magellan Midstream’s El Paso terminal. In addition, HEP agreed to become operator of the Osage Pipeline. This exchange was accounted for at carry-over basis with no resulting gain or loss. HEP’s acquisitions from us are eliminated upon consolidation and have no impact on the consolidated financial statements. HEP Common Unit Continuous Offering Program On May 10, 2016, HEP established a continuous offering program under which HEP may issue and sell common units from time to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million . As of June 30, 2016 , HEP has issued 444,799 units under this program, providing $14.9 million in gross proceeds. In connection with this program and to maintain the 2% general partner interest, we made capital contributions totaling $0.3 million as of June 30, 2016 . HEP intends to use the net proceeds for general partnership purposes, which may include funding working capital, repayment of debt, acquisitions and capital expenditures. Amounts repaid under HEP’s credit facility may be reborrowed from time to time. As a result of this transaction and resulting HEP ownership changes, we adjusted additional capital and equity attributable to HEP's noncontrolling interest holders to reallocate HEP's equity among its unitholders. Transportation Agreements HEP serves our refineries under long-term pipeline, terminal and tankage throughput agreements and refinery processing tolling agreements expiring from 2019 through 2030. Under these agreements, we pay HEP fees to transport, store and process throughput volumes of refined products, crude oil and feedstocks on HEP’s pipeline, terminals, tankage, loading rack facilities and refinery processing units that result in minimum annual payments to HEP including UNEV (a consolidated subsidiary of 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 or Federal Energy Regulatory Commission index. As of July 1, 2016, these agreements result in minimum annualized payments to HEP of $263.6 million .

Fair Value Measurements

Fair Value Measurements	6 Months Ended
	Jun. 30, 2016
Financial Instruments, Owned, at Fair Value [Abstract]
Financial Instruments	Fair Value Measurements 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. HEP’s outstanding credit agreement borrowings and HFC’s term loan also approximate fair value as interest rates are reset frequently at current interest rates on both debt instruments. 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 estimated fair values of marketable securities, derivative instruments and senior notes at June 30, 2016 and December 31, 2015 were as follows: Fair Value by Input Level Carrying Amount Fair Value Level 1 Level 2 Level 3 (In thousands) June 30, 2016 Assets: Marketable securities $ 81,328 $ 81,328 $ — $ 81,328 $ — NYMEX futures contracts 115 115 115 — — Commodity price swaps 23,075 23,075 — 23,075 — Forward contracts 442 442 — 442 — Total assets $ 104,960 $ 104,960 $ 115 $ 104,845 $ — Liabilities: Commodity price swaps $ 47,082 $ 47,082 $ — $ 47,082 $ — Forward contracts 933 933 — 933 — HollyFrontier senior notes 246,174 265,313 — 265,313 — HEP senior notes 297,136 301,500 — 301,500 — HEP interest rate swaps 405 405 — 405 — Total liabilities $ 591,730 $ 615,233 $ — $ 615,233 $ — December 31, 2015 Assets: Marketable securities $ 144,019 $ 144,019 $ — $ 144,019 $ — NYMEX futures contracts 3,469 3,469 3,469 — — Commodity price swaps 37,097 37,097 — 37,097 — HEP interest rate swaps 304 304 — 304 — Total assets $ 184,889 $ 184,889 $ 3,469 $ 181,420 $ — Liabilities: Commodity price swaps $ 98,930 $ 98,930 $ — $ 98,930 $ — HEP senior notes 296,752 295,500 — 295,500 — HEP interest rate swaps 114 114 — 114 — Total liabilities $ 395,796 $ 394,544 $ — $ 394,544 $ — Level 1 Instruments Our NYMEX futures contracts are exchange traded and are measured and recorded at fair value using quoted market prices, a Level 1 input. Level 2 Instruments Investments in marketable securities, derivative instruments consisting of commodity price swaps and forward sales and purchase contracts and HEP’s interest rate swaps are measured and recorded at fair value using Level 2 inputs. The fair values of the commodity price and interest rate swap contracts are 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 swaps. The fair value of the marketable securities and senior notes is based on values provided by a third-party, which were derived using market quotes for similar type instruments, a Level 2 input. Level 3 Instruments We at times have forward commodity sales and purchase contracts for which quoted forward market prices are not readily available. The forward rate used to value these forward sales and purchase contracts are derived using a projected forward rate using quoted market rates for similar products, adjusted for regional pricing and grade differentials, a Level 3 input. The following table presents the changes in fair value of our Level 3 assets and liabilities (all related to derivative instruments) for the three and six months ended June 30, 2015 : Three Months Ended Six Months Ended Level 3 Instruments (In thousands) Liability balance at beginning of period $ (2,552 ) $ — Change in fair value: Recognized in other comprehensive income 6,404 3,852 Settlement date fair value of contractual maturities: Recognized in sales and other revenues (3,852 ) (3,852 ) Liability balance at end of period $ — $ — During the six months ended June 30, 2016 , we recognized goodwill and long-lived asset impairment charges based on fair value measurements (see Note 1). Also, we recognized a non-recurring fair value measurement of $44.4 million that relates to HEP’s equity interest in Osage in February 2016. The fair value measurements were based on a combination of valuation methods including discounted cash flows, and the guideline public company and guideline transaction methods, Level 3 inputs.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share is calculated as net income (loss) 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 restricted shares and performance share units. The following is a reconciliation of the denominators of the basic and diluted per share computations for net income (loss) attributable to HollyFrontier stockholders: Three Months Ended Six Months Ended 2016 2015 2016 2015 (In thousands, except per share data) Net income (loss) attributable to HollyFrontier stockholders $ (409,368 ) $ 360,824 $ (388,115 ) $ 587,700 Participating securities’ share in earnings 216 1,036 432 1,677 Net income (loss) attributable to common shares $ (409,584 ) $ 359,788 $ (388,547 ) $ 586,023 Average number of shares of common stock outstanding 175,865 191,355 176,301 193,202 Effect of dilutive variable restricted shares and performance share units (1) — 99 — 77 Average number of shares of common stock outstanding assuming dilution 175,865 191,454 176,301 193,279 Basic earnings (loss) per share $ (2.33 ) $ 1.88 $ (2.20 ) $ 3.03 Diluted earnings (loss) per share $ (2.33 ) $ 1.88 $ (2.20 ) $ 3.03 (1) Excludes anti-dilutive restricted and performance share units of: — 349 — 379

Stock-Based Compensation

Stock-Based Compensation	6 Months Ended

Share-based Compensation [Abstract]
Stock-Based Compensation	Stock-Based Compensation As of June 30, 2016 , we have two principal share-based compensation plans (collectively, the “Long-Term Incentive Compensation Plan”). The compensation cost charged against income for these plans was $6.0 million and $6.1 million for the three months ended June 30, 2016 and 2015 , respectively, and $8.6 million and $12.5 million for the six months ended June 30, 2016 and 2015 , respectively. Our accounting policy for the recognition of compensation expense for awards with pro-rata vesting is to expense the costs ratably over the vesting periods. Additionally, HEP maintains a share-based compensation plan for Holly Logistic Services, L.L.C.’s non-employee directors and certain executives and employees. Compensation cost attributable to HEP’s share-based compensation plan was $0.5 million and $0.9 million for the three months ended June 30, 2016 and 2015 , respectively, and $1.2 million and $1.8 million for the six months ended June 30, 2016 and 2015 , respectively. Restricted Stock and Restricted Stock Units Under our Long-Term Incentive Compensation Plan, we grant certain officers and other key employees restricted stock and restricted stock unit awards with awards generally vesting over a period of one to three years. Restricted stock award recipients are generally entitled to all the rights of absolute ownership of the restricted shares from the date of grant including the right to vote the shares and to receive dividends. Upon vesting, restrictions on the restricted shares lapse at which time they convert to common shares. In addition, we grant non-employee directors restricted stock unit awards, which typically vest over a period of one year and are payable in stock. The fair value of each restricted stock and restricted stock unit award is measured based on the grant date market price of our common shares and is amortized over the respective vesting period. A summary of restricted stock and restricted stock unit activity and changes during the six months ended June 30, 2016 is presented below: Restricted Stock and Restricted Stock Units Grants Weighted Average Grant Date Fair Value Aggregate Intrinsic Value ($000) Outstanding at January 1, 2016 (non-vested) 722,525 $ 47.50 Granted 9,618 33.81 Vesting (transfer/conversion to common stock) (377 ) 43.77 Forfeited (12,551 ) 47.81 Outstanding at June 30, 2016 (non-vested) 719,215 $ 47.32 $ 17,096 For the six months ended June 30, 2016 , restricted stock and restricted stock units vested having a grant date fair value of $16 thousand . As of June 30, 2016 , there was $16.6 million of total unrecognized compensation cost related to non-vested restricted stock and restricted stock unit grants. That cost is expected to be recognized over a weighted-average period of 1.2 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 three years. Under the terms of our performance share unit grants, awards are subject to “financial performance” and “market performance” criteria. Financial performance is based on our financial performance compared to a peer group of independent refining companies, while market performance is based on the relative standing of total shareholder return achieved by HollyFrontier compared to peer group companies. The number of shares ultimately issued under these awards can range from zero to 200% of target award amounts. As of June 30, 2016 , estimated share payouts for outstanding non-vested performance share unit awards averaged approximately 80% of target amounts. A summary of performance share unit activity and changes during the six months ended June 30, 2016 is presented below: Performance Share Units Grants Outstanding at January 1, 2016 (non-vested) 637,938 Granted 5,520 Forfeited (146,186 ) Outstanding at June 30, 2016 (non-vested) 497,272 As of June 30, 2016 , there was $10.2 million of total unrecognized compensation cost related to non-vested performance share units having a grant date fair value of $46.08 per unit. That cost is expected to be recognized over a weighted-average period of 1.4 years.

Cash, Cash Equivalents, and Short-term Investments [Abstract]
Cash And Cash Equivalents And Investments In Marketable Securities	Cash and Cash Equivalents and Investments in Marketable Securities Our investment portfolio at June 30, 2016 consisted of cash, cash equivalents and investments in marketable securities. We currently invest in marketable debt securities with the maximum maturity or put date of any individual issue generally not greater than one year from the date of purchase, which are usually held until maturity. All of these instruments are classified as available-for-sale and are reported at fair value. 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 or maturity, realized gains on our marketable debt securities are recognized as interest income. These gains are computed based on the specific identification of the underlying cost of the securities, net of unrealized gains and losses previously reported in other comprehensive income. Unrealized gains and losses on our available-for-sale securities are due to changes in market prices and are considered temporary. The following is a summary of our marketable securities as of June 30, 2016 and December 31, 2015 : Amortized Cost Gross Unrealized Gain Gross Unrealized Loss Fair Value (Net Carrying Amount) (In thousands) June 30, 2016 Certificates of deposit $ 1,700 $ — $ — $ 1,700 Commercial paper 17,424 6 — 17,430 Corporate debt securities 16,038 — (5 ) 16,033 State and political subdivisions debt securities 46,158 9 (2 ) 46,165 Total marketable securities $ 81,320 $ 15 $ (7 ) $ 81,328 December 31, 2015 Commercial paper $ 22,876 $ 1 $ (2 ) $ 22,875 Corporate debt securities 32,311 — (41 ) 32,270 State and political subdivisions debt securities 88,935 6 (67 ) 88,874 Total marketable securities $ 144,122 $ 7 $ (110 ) $ 144,019 Interest income recognized on our marketable securities was $0.1 million and $0.5 million for the three months ended June 30, 2016 and 2015 , respectively, and $0.1 million and $0.9 million for the six months ended June 30, 2016 and 2015 , respectively.

(2) Finished products include gasolines, jet fuels, diesels, lubricants, asphalts, LPG’s and residual fuels. (3) Process chemicals include additives and other chemicals. Inventories, which are valued at the lower of LIFO cost or market, reflect a valuation reserve of $429.9 million and $624.5 million at June 30, 2016 and December 31, 2015 , respectively. The December 31, 2015 market reserve of $624.5 million was reversed due to the sale of inventory quantities that gave rise to the 2015 reserve. A new market reserve of $429.9 million was established as of June 30, 2016 based on market conditions and prices at that time. The effect of the change in lower of cost or market reserve was a decrease to cost of goods sold totaling $138.5 million and $135.5 million for the three months ended June 30, 2016 and 2015 , respectively, and $194.6 million and $142.0 million for the six months ended June 30, 2016 and 2015 , respectively.

Environmental Expense and Liabilities [Abstract]
Environmental	Environmental Environmental costs are charged to operating expenses if they relate to an existing condition caused by past operations and do not contribute to current or future revenue generation. We have ongoing investigations of environmental matters at various locations as part of our assessment process to determine the amount of environmental obligation we may have, if any, with respect to these matters for which we have recorded the estimated cost of the studies. Liabilities are recorded when site restoration and environmental remediation, cleanup and other obligations are either known or considered probable and can be reasonably estimated. Such estimates are undiscounted and require judgment with respect to costs, time frame and extent of required remedial and cleanup activities and are subject to periodic adjustments based on currently available information. Recoveries of environmental costs through insurance, indemnification arrangements or other sources are included in other assets to the extent such recoveries are considered probable. We expensed $0.5 million and $0.1 million for the three months ended June 30, 2016 and 2015 , respectively, and $1.3 million and $4.6 million for the six months ended June 30, 2016 and 2015 , respectively, for environmental remediation obligations. The accrued environmental liability reflected in our consolidated balance sheets was $95.8 million and $98.1 million at June 30, 2016 and December 31, 2015 , respectively, of which $81.7 million and $83.5 million , respectively, were classified as other long-term liabilities. These accruals include remediation and monitoring costs expected to be incurred over an extended period of time (up to 30 years for certain projects). The amount of our accrued liability could increase in the future when the results of ongoing investigations become known, are considered probable and can be reasonably estimated.

Debt	Debt HollyFrontier Credit Agreement We have a $1 billion senior unsecured revolving credit facility maturing in July 2019 (the “HollyFrontier Credit Agreement”), which may be used for revolving credit loans and letters of credit from time to time and is available to fund general corporate purposes. Indebtedness under the HollyFrontier Credit Agreement is recourse to HollyFrontier. During the six months ended June 30, 2016 , we received advances totaling $315.0 million and repaid $315.0 million under the HollyFrontier Credit Agreement. At June 30, 2016 , we were in compliance with all covenants, had no outstanding borrowings and had outstanding letters of credit totaling $3.3 million under the HollyFrontier Credit Agreement. HEP Credit Agreement In March 2016, HEP amended its senior secured revolving credit facility maturing in November 2018 (the “HEP Credit Agreement”), increasing the size of the facility from $850 million to $1.2 billion . The HEP Credit Agreement 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. During the six months ended June 30, 2016 , HEP received advances totaling $239.0 million and repaid $165.0 million under the HEP Credit Agreement. At June 30, 2016 , HEP was in compliance with all of its covenants, had outstanding borrowings of $786.0 million and no outstanding letters of credit under the HEP Credit Agreement. HEP’s obligations under the HEP Credit Agreement are collateralized by substantially all of HEP’s assets. Indebtedness under the HEP Credit Agreement involves recourse to HEP Logistics Holdings, L.P., its general partner, and is 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 recourse to our other assets. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries. HollyFrontier Senior Notes In March 2016, we issued $250 million in aggregate principal amount of 5.875% senior notes (the “HollyFrontier Senior Notes”) maturing April 2026 . The HollyFrontier Senior Notes are unsecured and unsubordinated obligations of ours and rank equally with all our other existing and future unsecured and unsubordinated indebtedness. In June 2015, we redeemed our $150.0 million aggregate principal amount of 6.875% senior notes maturing November 2018 at a redemption cost of $155.2 million at which time we recognized a $1.4 million early extinguishment loss consisting of a $5.2 million debt redemption premium, net of an unamortized premium of $3.8 million . HollyFrontier Financing Obligation In March 2016, we extinguished a financing obligation at a cost of $39.5 million and recognized an $8.7 million loss on the early termination. The financing obligation related to a sale and lease-back of certain crude oil tankage that we sold to an affiliate of Plains in October 2009 for $40.0 million . HollyFrontier Term Loan In April 2016, we entered into a $350 million senior unsecured term loan (the “HollyFrontier Term Loan”) maturing in April 2019. The HollyFrontier Term Loan is fully drawn and may be used for general corporate purposes. Indebtedness under the HollyFrontier Term Loan is recourse to HollyFrontier. HEP Senior Notes HEP has $300 million aggregate principal amount of 6.5% senior notes maturing March 2020 . In July 2016, HEP issued $400 million in aggregate principal amount of 6.0% HEP senior notes maturing in 2024 in a private placement. HEP used the net proceeds to repay indebtedness under the HEP Credit Agreement. The 6.5% and 6.0% 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 guaranteed by HEP’s wholly-owned subsidiaries. HEP’s creditors have no 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: June 30, December 31, (In thousands) HollyFrontier 5.875% Senior Notes Principal $ 250,000 $ — Unamortized discount and debt issuance costs (3,826 ) — 246,174 — Term loan Principal 350,000 — Debt issuance costs (1,187 ) — 348,813 — Financing Obligation — 31,288 Total HollyFrontier long-term debt 594,987 31,288 HEP Credit Agreement 786,000 712,000 HEP 6.5% Senior Notes Principal 300,000 300,000 Unamortized discount and debt issuance costs (2,864 ) (3,248 ) 297,136 296,752 Total HEP long-term debt 1,083,136 1,008,752 Total long-term debt $ 1,678,123 $ 1,040,040 We capitalized interest attributable to construction projects of $3.5 million and $2.5 million for the three months ended June 30, 2016 and 2015 , respectively, and $4.2 million and $5.4 million for the six months ended June 30, 2016 and 2015 , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments And Hedging Activities	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, forward purchase and sales 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. Accounting Hedges We have swap contracts serving as cash flow hedges against price risk on forecasted purchases of natural gas. We also periodically have forward sales contracts that lock in the prices of future sales of crude oil and refined product and swap contracts serving as cash flow hedges against price risk on forecasted purchases of WTI crude oil and forecasted sales of refined product. These contracts have been designated as accounting hedges and are measured at fair value with offsetting adjustments (gains/losses) recorded directly to other comprehensive income. These fair value adjustments are later reclassified to earnings as the hedging instruments mature. 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. Any hedge ineffectiveness is also recognized in earnings. The following table presents the pre-tax effect on other comprehensive income (“OCI”) and earnings due to fair value adjustments and maturities of commodity price swaps and forward sales under hedge accounting: Unrealized Gain (Loss) Recognized in OCI Gain (Loss) Recognized in Earnings Due to Settlements Gain (Loss) Attributable to Hedge Ineffectiveness Recognized in Earnings Location Amount Location Amount (In thousands) Three Months Ended June 30, 2016 Change in fair value $ (5,138 ) Loss reclassified to earnings due to settlements 21,910 Sales and other revenunes $ (15,897 ) Amortization of discontinued hedges reclassified to earnings 270 Operating expenses (6,283 ) Operating expenses $ — Total $ 17,042 $ (22,180 ) $ — Three Months Ended June 30, 2015 Change in fair value $ 8,501 Sales and other revenues $ 49,752 Gain reclassified to earnings due to settlements (14,802 ) Cost of products sold (30,964 ) Sales and other revenues $ (140 ) Amortization of discontinued hedges reclassified to earnings 270 Operating expenses (4,256 ) Cost of products sold 2,494 Total $ (6,031 ) $ 14,532 $ 2,354 Six Months Ended June 30, 2016 Change in fair value $ (17,059 ) Loss reclassified to earnings due to settlements 32,966 Sales and other revenues $ (20,653 ) Amortization of discontinued hedge reclassified to earnings 540 Operating expenses (12,853 ) Operating expenses $ — Total $ 16,447 $ (33,506 ) $ — Six Months Ended June 30, 2015 Change in fair value $ (5,647 ) Sales and other revenues $ 98,932 Sales and other revenues $ (274 ) Gain reclassified to earnings due to settlements (19,494 ) Cost of products sold (71,733 ) Cost of products sold 3,738 Amortization of discontinued hedge reclassified to earnings 540 Operating expenses (8,245 ) Operating expenses 547 Total $ (24,601 ) $ 18,954 $ 4,011 As of June 30, 2016 , we have the following notional contract volumes related to outstanding derivative instruments serving as cash flow hedges against price risk on forecasted transactions: Notional Contract Volumes by Year of Maturity Derivative Instruments Total Outstanding Notional 2016 2017 Unit of Measure Natural gas price swaps - long 14,400,000 4,800,000 9,600,000 MMBTU Forward diesel contracts - short 75,000 75,000 — Barrels Physical crude contracts - short 275,000 275,000 — Barrels In 2013 , we dedesignated certain commodity price swaps (long positions) that previously received hedge accounting treatment. These contracts now serve as economic hedges against price risk on forecasted natural gas purchases totaling 14,400,000 MMBTU’s to be purchased ratably through 2017. As of June 30, 2016 , we have an unrealized loss of $ 1.6 million classified in accumulated other comprehensive income that relates to the application of hedge accounting prior to dedesignation that is amortized as a charge to operating expenses as the contracts mature. Economic Hedges We also have swap contracts that serve as economic hedges (derivatives used for risk management, but not designated as accounting hedges) to fix our purchase price on forecasted purchases of WTI crude oil, and to lock in basis spread differentials on forecasted purchases of crude oil and natural gas. Also, we have NYMEX futures contracts to lock in prices on forecasted purchases of inventory. These contracts are measured at fair value with offsetting adjustments (gains/losses) recorded directly to income.

As of June 30, 2016 , HEP had two interest rate swap contracts with identical terms that hedge its exposure to the cash flow risk caused by the effects of LIBOR changes on $150.0 million in credit agreement advances. The swaps effectively convert $150.0 million of LIBOR based debt to fixed rate debt having an interest rate of 0.74% plus an applicable margin of 2.25% as of June 30, 2016 , which equaled an effective interest rate of 2.99% . Both of these swap contracts mature in July 2017 and have been designated as cash flow hedges. To date, there has been no ineffectiveness on these cash flow hedges.

Assuming commodity prices and interest rates remain unchanged, an unrealized loss of $16.2 million will be effectively transferred from accumulated other comprehensive income into the statement of income as the hedging instruments contractually mature over the next twelve-month period.

In May 2015, our Board of Directors approved a $1 billion share repurchase program, which replaced all existing share repurchase programs, authorizing us 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 and corporate, regulatory and other relevant considerations. This program may be discontinued at any time by the Board of Directors. As of June 30, 2016 , we had remaining authorization to repurchase up to $178.8 million under this stock repurchase program. In addition, we are authorized by our Board of Directors to repurchase shares in an amount sufficient to offset shares issued under our compensation programs. During the second quarter of 2015, we entered into an accelerated share repurchase agreement with a large financial institution to repurchase $300.0 million of our outstanding common stock. In May 2015, we repurchased 5.5 million shares, representing 80% of the amount paid based on then-market prices. For the remaining shares to be repurchased, we recorded a forward contract indexed to our own common stock in the amount of $60.0 million at June 30, 2015 . The agreement was completed in September 2015, at which time we acquired an additional 1.2 million shares upon settlement of the forward contract.

Segment Reporting [Abstract]
Segment Information	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 HFC Asphalt (aggregated as a reportable segment). 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. HFC Asphalt operates various asphalt terminals in Arizona, New Mexico and Oklahoma. The HEP segment includes all of the operations of HEP, which owns and operates logistics and refinery assets consisting of petroleum product and crude oil pipelines, terminals, tankage, loading rack facilities and processing units in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. The HEP segment also includes a 75% ownership interest in UNEV (a consolidated subsidiary of HEP); a 50% ownership interest in each of the Frontier Pipeline, Osage Pipeline and the Cheyenne Pipeline and a 25% ownership interest in the SLC Pipeline. 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. Due to certain basis differences, 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, 2015 .

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Accounts Receivable	Accounts Receivable: Our accounts receivable consist of amounts due from customers that are primarily companies in the petroleum industry. 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 $2.3 million at both June 30, 2016 and December 31, 2015 .
Inventories	Inventories: Inventories are stated at the lower of cost, using the last-in, first-out (“LIFO”) method for crude oil, unfinished and finished refined products and the average cost method for materials and supplies, or market. In periods of rapidly declining prices, LIFO inventories may have to be written down to market value due to the higher costs assigned to LIFO layers in prior periods. In addition, the use of the LIFO inventory method may result in increases or decreases to cost of sales in years that inventory volumes decline as the result of charging cost of sales with LIFO inventory costs generated in prior periods. An actual valuation of inventory under the LIFO method is 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	Inventory Repurchase Obligations: We periodically enter into same-party sell / buy transactions, whereby we sell certain refined product inventory and subsequently repurchase the inventory in order to facilitate delivery to certain locations. Such sell / buy transactions are accounted as inventory repurchase obligations under which proceeds received under the initial sell is recognized as an inventory repurchase obligation that is subsequently reversed when the inventory is repurchased. For the six months ended June 30, 2016 and 2015 , we received proceeds of $29.8 million and $50.0 million , respectively, and repaid $30.2 million and $51.0 million , respectively, under these sell / buy transactions.
Income Tax, Policy [Policy Text Block]	Income Taxes : Provisions for income taxes include deferred taxes resulting from temporary differences in income for financial and tax purposes, using the liability method of accounting for income taxes. The liability method requires the effect of tax rate changes on deferred income taxes to be reflected in the period in which the rate change was enacted. The liability method also requires that deferred tax assets be reduced by a valuation allowance unless it is more likely than not that the assets will be realized. For the six months ended June 30, 2016 , we recorded an income tax benefit of $15.7 million compared to expense of $336.7 million for the six months ended June 30, 2015 . This decrease was due principally to a pre-tax loss during the six months ended June 30, 2016 compared to pre-tax earnings in the same period of 2015 . Our effective tax rates, before consideration of earnings attributable to the noncontrolling interest, were 4.3% and 35.3% for the six months ended June 30, 2016 and 2015 , respectively. The year-over-year decrease in the effective tax rate is due principally to the effects of the second quarter $309.3 million goodwill impairment charge, a significant driver of our $364.8 million loss before income taxes for the six months ended June 30, 2016 , that is not deductible for income tax purposes.
Inventory Repurchase Agreements	Inventory Repurchase Obligations: We periodically enter into same-party sell / buy transactions, whereby we sell certain refined product inventory and subsequently repurchase the inventory in order to facilitate delivery to certain locations. Such sell / buy transactions are accounted as inventory repurchase obligations under which proceeds received under the initial sell is recognized as an inventory repurchase obligation that is subsequently reversed when the inventory is repurchased. For the six months ended June 30, 2016 and 2015 , we received proceeds of $29.8 million and $50.0 million , respectively, and repaid $30.2 million and $51.0 million , respectively, under these sell / buy transactions.
New Accounting Pronouncements	New Accounting Pronouncements Leases In February 2016, Accounting Standard Update (“ASU”) 2016-02, “Leases,” was issued requiring leases to be measured and recognized as a lease liability, with a corresponding right-of-use asset on the balance sheet. This standard has an effective date of January 1, 2019, and we are evaluating the impact of this standard. Consolidation In February 2015, ASU 2015-02, “Consolidation,” was issued to improve consolidation guidance for certain legal entities. It modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, affects the consolidation analysis of reporting entities involved with VIEs, particularly those that have fee arrangements and related party provisions and provides a scope exception from consolidation guidance for certain reporting entities that comply with or operate in accordance with requirements that are similar to those included in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. We adopted this standard effective January 1, 2016, which did not affect our financial position or results of operations. Revenue Recognition In May 2014, ASU 2014-09, “Revenue from Contracts with Customers,” was issued requiring revenue to be recognized when promised goods or services are transferred to customers in an amount that reflects the expected consideration for these goods or services. This standard has an effective date of January 1, 2018, and we are evaluating the impact of this standard.
